Fixes related to handling of C++ methods (handle destructors
[deliverable/binutils-gdb.git] / gdb / ChangeLog
1 Tue Nov 12 13:43:26 1991 Per Bothner (bothner at cygnus.com)
2
3 * symtab.c (decode_line_1): Remove spurious call to operator_chars.
4
5 Allow setting breakpoints on C++ destructors.
6 * valops.c (destructor_name_p): Don't check TYPE_HAS_DESTRUCTOR,
7 since it lies. Rely on callers to catch missing destructors.
8 * symtab.c (decode_line_1): For example (see above), here.
9 * buildsym.c, symtab.h: Remove TYPE_FLAGS_HAS{CON,DE}STRUCTOR
10 flags since they are no longer used.
11
12 Fixes to support C++ methods with functional parameters.
13 * c-exp.y (func_mod rule): Allow (and ignore) list of parameter
14 types in a function type.
15 * eval.c (parse_and_eval_type), value.h: New function,
16 parse_and_eval_type, is based on old code from check_stub_method.
17 But don't actually evaluate the cast, since that calls
18 value_cast(), whcih may fail. Just extract the type
19 from the parsed expression.
20 * values.c (check_stub_method): While looping through the
21 arguments, adjust depth *after* parameter has been handled.
22 Replace call and setup of parse_and_eval with new function
23 parse_and_eval_type.
24
25 Tue Nov 12 09:40:07 1991 Fred Fish (fnf at cygnus.com)
26
27 * utils.c, rem-multi.shar: Remove fixed arg count version of
28 concat().
29
30 * altos-xdep.c, arm-xdep.c, coffread.c, command.c, convex-xdep.c,
31 core.c, dwarfread.c, gould-xdep.c, infcmd.c, language.c,
32 m88k-xdep.c, main.c, printcmd.c, pyr-xdep.c, source.c,
33 sun386-xdep.c, symm-xdep.c, umax-xdep.c, values.c, xcoffread.c:
34 Change all instances of use of fixed args concat() to variable
35 args concat() now located in libiberty.
36

44 xm-rs6000.h: New files.
45 * xcoffexec.c: New file for handling AIX shared libraries.
46
47 Mon Nov 11 19:14:31 1991 Fred Fish (fnf at cygnus.com)
48
49 * core.c: Minor rewording of message to user containing name of
50 (and possibly arguments to) the program that generated a core
51 file.
52
53 * elfread.c: Remove the register_addr() stub now that it is no
54 longer needed.
55
56 * procfs.c: Move misplaced #endif for ATTACH_DETACH. Add new
57 fetch_core_registers() function for core file support.
58
59 Sat Nov 9 13:37:57 1991 Fred Fish (fnf at cygnus.com)
60
61 * dwarfread.c (dwarf_psymtab_to_symtab): Remove leftover call
62 to do_cleanups() which resulted from a previous change.
63
64 * elfread.c: Re-enable compilation of register_addr() stub
65 whenever it is not supplied by coredep.c
66
67 Sat Nov 9 00:40:32 1991 John Gilmore (gnu at cygnus.com)
68
69 Add tracking of object files (that contain symbols) to gdb.
70 This includes a "struct objfile" that owns symtabs and psymtabs
71 that were read in from that binary file.
72
73 * symfile.h: Add struct objfile. Add pointer to the objfile
74 into the struct sym_fns.
75 Replace global `symfile' and `symfile_mtime' with

86 (allocate_symtab): Takes objfile as new parameter, chains them.
87 Handle INIT_EXTRA_SYMTAB_INFO.
88 (free_all_psymtabs, free_all_symtabs): Move here from symmisc.c.
89
90 * dbxread.c: Make more errors into complaints.
91 (push_subfile, pop_subfile): Move to buildsym.c.
92 (dbx_symfile_read, dbx_symfile_init, fill_symbuf, read_dbx_symtab,
93 start_psymtab, psymtab_to_symtab_1, read_ofile_symtab,
94 dbx_psymtab_to_symtab, ): Use bfd ops, don't use file descriptor.
95 Pass objfile. Change callers.
96 (fill_symbuf, SWAP_SYMBOL): Take bfd as arg.
97 (read_dbx_symtab): Just wipe out new symbols, not all, on error.
98 (end_psymtab): Blow away psymtab if empty.
99 (process_symbol_pair): Swallow into read_ofile_symtab.
100 (process_one_symbol): Use push_context and pop_context.

102
103 * buildsym.c (end_symtab): Pass objfile.
104 (dbx_lookup_type): Handle null typevector.
105 (dbx_alloc_type): Check file number, not sym number, for -1.

107 (start_symtab): Default typevector is empty. Keep reusing same
108 context_stack.
109 (end_symtab): Take objfile argument and pass it to
110 allocate_symtab. Don't make a symtab if no blocks or symbols.
111 Handle empty typevector.
112 (push_context): New function for context stack nesting.
113 (read_type): Mark FIXME where we need to reintroduce type smashing.
114
115 * buildsym.h (pop_context): Macro, paired with push_context.
116 (subfile_stack): Move here from dbxread.c.
117
118 * coffread.c (end_symtab, read_coff_symtab): Take and use objfile arg.
119 (read_coff_symtab): Cleanup by freeing objfile, not all symtabs.
120
121 * mipsread.c (read_mips_symtab, parse_partial_symbols, parse_fdr,
122 new_psymtab, new_symtab): Take and use objfile arg.
123
124 * dwarfread.c (scan_compilation_units, start_psymtab,
125 process_dies, end_symtab, dwarf_build_psymtabs,

131
132 * elfread.c, target.c: Minor changes to accommodate objfiles.
133 * symtab.h: partial_symbol_table has no symfile_name member now.
134 (fn_fieldlists voffset): avoid non-int bitfield.
135 (struct symtab): Add objfile * and objfile_chain * of symtabs.
136 (struct partial_symtab): Add objfile * and objfile_chain * of
137 psymtabs. Remove symfile_name.
138
139 * symmisc.c: Lose free_all_symtabs, free_all_psymtabs.
140 (printsyms_command): Rename from print_symtabs. Add selective
141 listing if 2nd argument given. Print objfile info.
142 (printpsyms_command): Rename from print_partial_symtabs. Ditto all.
143 (printobjfiles_command): New; prints objfiles lists, and checks
144 for consistency of symtab, psymtab, and objfile lists.
145
146 * symfile.h, symfile.c, symtab.h: Lint
147
148 Fri Nov 8 23:38:48 1991 John Gilmore (gnu at cygnus.com)
149
150 * command.c: Include param.h.
151 * defs.h (warning_setup, warning): Declare.
152 * expprint.c (print_subexp, UNOP_MEMVAL case): Lint.
153 * inflow.c (new_tty): Use USE_O_NOCTTY #define.
154 * language.c, printcmd.c (print_scalar_formatted), signame.c,
155 stack.c: lint.
156
157 Thu Nov 7 18:26:15 1991 Steve Chamberlain (sac at rtl.cygnus.com)
158
159 * Makefile.in: link with libiberty after libreadline, since
160 readline might want something in libiberty.
161 * m88k-xdep.c: Fixed the register offsets in the ptrace_user
162 struct for BCS 88k machines.
163 * xm-m88k.h: don't define USIZE if already defined.
164 * configure.in: Added delta88 target.
165
166 Thu Nov 7 04:51:19 1991 John Gilmore (gnu at cygnus.com)
167
168 * am29k-pinsn.c, am29k-opcode.h: Fix decoding of mtacc, dmac, fmac.
169
170 * tm-*.h: Remove READ_DBX_FORMAT, COFF_FORMAT, and
171 READ_MIPS_FORMAT, which have been unused since BFD. Still
172 remaining is COFF_NO_LONG_FILE_NAMES.
173 * tm-sun3.h, tm-altos.h: Remove detritus accidentally left from
174 function calling code moved to m68k-tdep.c.
175
176 Wed Nov 6 17:21:59 1991 John Gilmore (gnu at cygnus.com)
177
178 * coffread.c: Eliminate c_nsyms in favor of c_naux.
179 Complain if no auxents on .bf and .ef FCN symbols, and assume
180 lots of line numbers.
181 (init_linenos, enter_linenos): Use a sentinel at the end of the
182 read-in linenos, to make for a fast, safe loop-end test.
183
184 Wed Nov 6 02:54:08 1991 Steve Chamberlain (sac at cygnus.com)
185
186 * coffread.c (read_coff_symtab): coffread used to rely on the
187 x_sym.x_misc.x_lnsz.x_lnno field giving the # of linnos in a
188 function. Two of the formats I'm using (29k and 88k) don't seem to
189 set it. Ths patch to fcn_last_line and (enter_linenos) is an
190 attempt to use the actual size of the linno table in the file to set
191 the number of linenos to process.
192
193 Tue Nov 5 22:47:46 1991 Steve Chamberlain (sac at cygnus.com)
194
195 * Makefile.in: put a - infront of the mv y.tab.c c-exp.tab.c and
196 mv y.tab.c m2-exp.tab.c, so that if bison is used, and the files
197 are created in place, so the mv fails, then the make continues.
198
199 Tue Nov 5 16:47:47 1991 Per Bothner (bothner at cygnus.com)
200
201 Add C++ as a separate language.
202 * defs.h (enum language): Add language_cplus.
203 * dwarfread.c (end_symtab): Support language_cplus.
204 * c-exp.y: Add new struct language_defn cplus_language_defn.
205 Don't set c to be the default language (see main.c).
206 * c-exp.y (yylex): Only look for field of this if
207 language is C++. (First difference from C!)
208 * language.c: Add case branches for C++ (currently, all
209 the same as C). Also, add c++ to "usage" note for "set lang".
210 * valprint.c (typedef_print). Add case branches for C++.
211 * main.c (main): New way to set initial language: Look at
212 file extension of psymtab containing main(). (Same as we
213 do for symtabs, but avoid loading the symtab yet.)
214 * symtab.c: New routine find_main_psymtab(), used by main()
215 to set initial language.
216 * symfile.c (allocate_symtab): Move code for mapping file
217 extensions-> languages to new deduce_language_from_filename().
218
219 Fix a C++ problem when looking for methods in super-classes.
220 There was confusion between base and derived types.
221 * valops.c (value_fn_field): Change function interface.
222 * values.c: Use new value_fn_field interface.
223
224 Mon Nov 4 10:49:33 1991 Per Bothner (bothner at cygnus.com)
225
226 * infrun.c: Fixed typo in comment.
227 * utils.c: All the v*fprintf emulation is now in libiberty,
228 so we can get rid of some junk.
229 * xm-sun3os4.h, xm-sun4os4.h, xconfig/decstation, xconfig/i386sco,
230 xconfig/sun3os4, xconfig/sun4os4: Don`t need HAVE_STRSTR any more.
231 * m68k-pinsn.c (print_insn_arg): Support BB/BW/BL
232 type operands, as used by branch instructions.
233 * gmalloc.c: Fix prototype of memcpy.
234 * elfread.c: Comment out register_addr, since it conflicts
235 with the one in coredep.c.
236 * buildsym.h: Remove extern declarations of two functions
237 that are really static in buildsym.c.
238 * tm-mips.h: Add symbolic names for more registers.
239 * mips-xdep.c (store_inferior_registers): Use new register names.
240 * xm-mips.h: Simplify REGISTER_U_ADDR, since it is now
241 only used for core files, not ptrace. Therefore,
242 the KERNEL_U_ADDR hack is no longer needed.
243 The mapping to ptrace number is now in in mips-xdep.c.
244 * mips-xdep.c: Define REGISTER_PTRACE_ADDR (using the
245 mapping from the old REGISTER_U_ADDR), and use it
246 in {fetch,store}_inferior_registers.
247 * mipsread.c: Rename #include ecoff.h to new name coff-mips.h.
248 * mips-tdep.c (mips_push_dummy_frame, mips_pop_frame):
249 Save/restore FP regs correctly (?).
250 * dbxread.c: Remove duplicate define_symbol and type_synonym_name
251 (these had been previously moved to buildsym.c).
252 Hence, define_symbol becomes extern instead of static.
253 * buildsym.c (read_struct_type): Comment out bogus handling
254 of C++ operator methods. Minor hacking of reading of class
255 contexts. Make define_symbol non-static, so dbxread.c can call it.
256
257 Fri Nov 1 11:05:47 1991 John Gilmore (gnu at cygnus.com)
258
259 * mipsread.c (read_mips_symtab, read_the_mips_symtab): Use real
260 filename with error messages.
261 * stack.c (frame_select_command): Rename to select_frame_command
262 to avoid "fr" and "fra" having nonunique completions.
263 * symfile.c (sort_symtab_syms): Ignore sort of zero symtab *.
264 (symfile_init): Print file format name when unable to handle it.
265 (free_named_symtabs): Use BLOCKVECTOR rather than obsolete BLOCKLIST.
266 * symmisc.c (free_symtab): Only free linetable if nonzero.
267 * symtab.h: Remove obsolete BLOCKLIST macros.
268
269 Thu Oct 31 18:12:43 1991 Stu Grossman (grossman at cygnus.com)
270
271 * infrun.c (wait_for_inferior): another stepi/nexti fix. Ensure
272 that stop_step is 1 at bottom of main loop. I don't know why this
273 needs to be done, but it helps me sleep better at night.
274
275 Sun Oct 27 18:18:39 1991 Stu Grossman (grossman at cygnus.com)
276
277 * main.c (initialize_history): Read history after reading all
278 init files.
279
280 Sun Oct 27 14:09:25 1991 John Gilmore (gnu at cygnus.com)
281
282 * buildsym.c: Break out initial malloc sizes.
283 (record_line): Record directly in a subfile. Alloc on demand.
284 (compare_line_numbers): Add from xcoffread.c.
285 (end_symtab): New params say whether to sort pendings and
286 linetable. Patch block stabs if defined. Shrink linetable before
287 allocating the symtab.
288 * buildsym.h: Delete line_vector* and prev_line_number. Add
289 global_stabs and file_stabs for xcoffread.
290 * dbxread.c (start_subfile): Move to buildsym. Change above calls.
291 * symtab.h: LINETABLE(symtab) can now be null. Zap LINELIST.
292 * symmisc.c, symtab.c: Cope with null LINETABLEs.
293
294 * blockframe.c: Pass fromleaf to INIT_EXTRA_FRAME_INFO.
295 * tm-29k.h, tm-88k.h, tm-i960.h, tm-irix3.h, tm-mips.h, tm-pyr.h,
296 tm-sparc.h: Accept fromleaf parameter.
297 * c-exp.y (yyerror): Pass error message if given.
298 * configure.in: Add rs6000 host and target.
299 * inflow.c (new_tty): O_NOCTTY kludge for RS/6000.
300 * symfile.h (entry_point): Add.
301
302 Sat Oct 26 00:16:32 1991 John Gilmore (gnu at cygus.com)
303
304 * buildsym.c: New file. Breaks out symbol-table-building routines
305 from dbxread.c, so they can be shared with xcoffread.c.
306 * buildsym.h: New file. Declarations for buildsym.c users.
307 * dbxread.c: Remove large chunks into buildsym.c.
308 * Makefile.in: Add buildsym.c and buildsym.h.
309
310 * symfile.c (syms_from_bfd): New routine.
311 (add_symbol_file): Call it to do the real work.
312 (syms_from_bfd): Initialize entry_point before calling symfile_init.
313 * symtab.h, symfile.c, coffread.c, mipsread.c, dwarfread.c:
314 Avoid declaring or setting entry_point (symfile.h & symfile.c cope).
315
316 Fri Oct 25 18:59:32 1991 Per Bothner (bothner at cygnus.com)
317
318 Various fixes to improve g++ debugging.
319 * symtab.h: Add is_const and is_volatile flags for each method.
320 These are bit fields - take their space from voffset,
321 which shrinks to 30 bits. Since voffset is now a bitfield,
322 make it unsigned for portability. This changes its interpretation
323 slightly: Static methods now have voffset 1 instead of -1,
324 and virtual offsets start at 2, not 1.
325 * symtab.c: Renamed gdb_mangle_typename to gdb_mangle_name,
326 since it now returns an entire magled method name, not just
327 the type part. This avoids some duplication.
328 It also allows us to correctly mangle const and volatile
329 methods (using the new is_const and is_volatile bit fields
330 mentioned above).
331 * valprint.c (type_print_base), values.c (check_stub_method):
332 Simplify by using new gdb_mangle_name.
333 * values.c (value_headof): Fix to correctly handle single
334 inheritance (actually two fixes, either of which suffices).
335 * dbxread.c (read_struct_type): Handle const and volatile
336 method specifiers.
337 * dbxread.c (read_struct_type): Yet one more place where
338 we must handle '\\' continuations.
339 * valprint.c (vtbl_ptr_name): Add final '\0'.
340
341 Fri Oct 25 16:06:38 1991 Stu Grossman (grossman at cygnus.com)
342
343 * tm-sparc.h, tm-68k.h (EXTRACT_RETURN_VALUE): fix output of
344 short return values for sparc and 68k. Patch from Paul Eggert.
345
346 * coffread.c, coredep.c, i386-xdep.c: install patches for
347 SysV/386 3.2 from Mauro DePalma.
348
349 Fri Oct 25 02:02:13 1991 John Gilmore (gnu at cygnus.com)
350
351 * core.c (core_file_info), exec.c (exec_file_info): Print file
352 type. Use printf_filtered.
353
354 * valops.c (value_fetch_lazy): Avoid 0-length fetches.
355
356 Thu Oct 24 23:06:40 1991 Fred Fish (fnf at cygnus.com)
357
358 * dwarfread.c: Add casts to remove compiler warnings.
359
360 * tm-3b1.h, tm-68k.h, tm-altos.h, tm-amix.h, tm-hp300bsd.h,
361 tm-hp300hpux.h, tm-isi.h, tm-news.h, tm-pn.h, tm-sun2.h,
362 tm-sun3.h: Remove locally duplicated code for calling functions
363 in the inferior. The only differences were in the specific trap
364 vectors used and whether or not an fpu was present. These are
365 now handled by appropriate definitions of BPT_VECTOR and
366 HAVE_68881 respectively. Other minor obvious cleanups.
367
368 * valops.c: Correct a minor misspelling.
369
370 * utils.c: Remove local BSD/USG hacks that are now in libiberty.
371
372 * dwarfread.c: Remove prototype for dwarfwarn. Does not work
373 with <varargs.h>.
374
375 Thu Oct 24 09:33:44 1991 John Gilmore (gnu at cygnus.com)
376
377 * stack.c (frame_command): Always print. Use new
378 frame_select_command to select a frame without printing.
379
380 * dwarfread.c: Use <varargs.h>, since <stdarg.h> is not portable.
381
382 Thu Oct 24 01:32:51 1991 Fred Fish (fnf at cygnus.com)
383
384 * dwarfread.c: New file for DWARF debugging format support.
385
386 * elfread.c: New file for ELF object file format support.
387
388 * procfs.c: New file for SVR4 /proc (process file system) support.
389
390 * tm-amix.h, xm-amix.h, tconfig/amix, xconfig/amix: New files for
391 Amiga UNIX support.
392
393 * xm-svr4.h, tm-svr4.h: New files for SVR4 support.
394
395 * xm-m68k.h: New file for host machines with m68k cpu.
396
397 * Makefile.in: Add elfread.c and dwarfread.c to SFILES_MAINDIR.
398 Add elfread.o and dwarfread.o to OBS.
399
400 * symfile.h: Add "elf" to list of supported formats in comment.
401
402 * c-exp.y, defs.h, symtab.h, valprint.c: Add three new builtin
403 types to gdb, builtin_type_long_double, builtin_type_complex, and
404 builtin_type_double_complex. Add and use new TARGET_SHORT_BIT,
405 TARGET_INT_BIT, TARGET_LONG_BIT, TARGET_FLOAT_BIT,
406 TARGET_DOUBLE_BIT, TARGET_LONG_DOUBLE_BIT, TARGET_COMPLEX_BIT, and
407 TARGET_DOUBLE_COMPLEX_BIT, as the sizes in bits of the indicated
408 types on the target machine (ala the existing TARGET_LONG_LONG_BIT).
409
410 * infrun.c: When using SVR4 /proc interface instead of ptrace(),
411 call proc_set_exec_trap() to setup child to stop at first instruction.
412
413 * inftarg.c: When using SVR4 /proc interface, call proc_wait()
414 rather than wait().
415
416 * m68k-tdep.c: Add new routines supply_gregset(), fill_gregset(),
417 supply_fpregset(), and fill_fpregset(), which are machine
418 dependent support routines for SVR4 /proc interface.
419
420 * utils.c: Add warning_setup() and warning(). Warning() behaves
421 the same as error() except that it returns normally rather than
422 jumping back to command level. Modules that don't want to call
423 warning() for some reason, but want to produce their own warnings,
424 can call warning_setup() to ensure compatibility with the way
425 warning() and error() deal with the terminal.
426
427 * symtab.c: Make internal errors produce more useful messages.
428
429 * tm-68k.h: Move code that is duplicated in almost every single
430 m68k based machine's configuration files to this common file.
431 Duplications in the configuration files still need to be removed
432 (FIXME).
433
434 * infrun.c (child_create_inferior): System V versions must call
435 setpgrp() with no arguments, to comply with prototyping typically
436 in <unistd.h>.
437
438 * munch: Add support for SVR4 style nm output.
439
440 * dbxread.c, mipsread.c symmisc.c, symtab.c: Remove the object
441 file specific fields from the partial symbol table structure and
442 replace them with a pointer to private data for each different
443 flavor of object file reader to initialize appropriately.
444
445 Wed Oct 23 09:38:20 1991 John Gilmore (gnu at cygnus.com)
446
447 * xconfig/sun[34]os4: Add note about strstr botch on sunos4.0.3c
448 and previous.
449
450 * mipsread.c (fixup_undef_type): New function. If a struct /
451 union / enum is defined in a header file but nowhere else used,
452 (by typedefing, pointer referencing or declaration) the mipsread code
453 builds the complete tree for the structure but leaves its code as
454 TYPE_CODE_UNDEF as it doesn't know what kind of aggregate it is.
455 Guess its type based on the details of the members.
456
457 Tue Oct 22 18:04:32 1991 Stu Grossman (grossman at cygnus.com)
458
459 * infrun.c (wait_for_inferior): Check return value from
460 find_pc_line.
461
462 Mon Oct 21 17:47:03 1991 Stu Grossman (grossman at cygnus.com)
463
464 * infrun.c (wait_for_inferior): fix stepi/nexti that was broken
465 by my last edit to this routine.
466
467 Mon Oct 21 14:27:43 1991 John Gilmore (gnu at cygnus.com)
468
469 * tm-sun3.h (FIX_CALL_DUMMY): problem with cross debugging.
470 FIX_CALL_DUMMY does unaligned accesses and/or forgets to byte swap
471 the values before putting them into the dummy code. (From Peter
472 Schauer)
473
474 Mon Oct 21 10:04:39 1991 Steve Chamberlain (steve at rtl.cygnus.com)
475
476 * configure.in: added ebmon target.

534 dec3100 to decstation.
535
536 Mon Oct 14 13:37:50 1991 Roland H. Pesch (pesch at cygnus.com)
537
538 * doc/gdb.texinfo: Catch up to changes recorded here in ChangeLog
539 (nodes Continuing and Stepping; Memory; Targets) clarifications
540 due to Larry Breed
541
542 Fri Oct 11 23:27:06 1991 John Gilmore (gnu at cygnus.com)
543
544 * tm-{irix3,mips,nindy960,pn,symmetry,vx960}.h: Move
545 REGISTER_U_ADDR to corresponding xm- file. Sugg. by Peter Schauer.
546

548
549 * m68k-tdep.c (m68k_push_dummy_frame, m68k_pop_frame): Add
550 generic routines for calling inferior functions.
551
552 * blockframe.c (inside_main_scope, inside_entry_scope): New.
553
554 * copying.awk: Filter formfeeds out of copying & warrantee.
555 Make them available as `show copying' and `show warrantee' also.
556 * main.c (print_gnu_advertisement): Advt `show' commands.
557
558 Thu Oct 10 17:25:47 1991 John Gilmore (gnu at cygnus.com)
559
560 * mach386-xdep.c: Even when cross-compiling, leave in the
561 core-file reading code.
562 * core.c (get_core_registers): Avoid coredump if no .reg section.
563
564 Wed Oct 9 17:03:34 1991 John Gilmore (gnu at cygnus.com)
565
566 * mipsread.c, coffread.c: initialise TYPE_VPTR_FIELDNO to -1.
567 This avoids coredumps under `set print object on' in value_headof
568 (called erroneously by value_from_vtable_info) for `p &struct'
569 or `p *struct'. From Peter Schauer.
570
571 Mon Oct 7 00:06:52 1991 John Gilmore (gnu at cygnus.com)
572
573 * Makefile.in: Roll version to 4.1.2.
574 * dbxread.c: Use aout64.h, not a.out.gnu.h. Get external symbol entry
575 size from BFD (but, FIXME, we don't yet read external nlists's and
576 convert them to internal nlists's before handling them -- we still
577 assume they have the same size and alignment.) Use SET_NAMESTRING
578 everywhere useful.
579 * exec.c (exec_file_command): Move dead coff-encapsulation code
580 to BFD.
581 * m88k-tdep.c, m88k-xdep.c: Remove encap test and #inc <a.out.h>.
582
583 Fri Oct 4 22:30:06 1991 John Gilmore (gnu at cygnus.com)
584
585 * configure.in, tm-i386v.h, xm-i386v.h: Intel 386 Mach host port.
586 * xm-i386mach.h, mach386-xdep.c, xconfig/i386mach: New files.
587
588 Fri Oct 4 17:04:31 1991 Per Bothner (bothner at cygnus.com)
589
590 More patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
591 * mips-xdep.c (store_inferior_registers): Don't try to
592 write the (pseudo) FP.

594 setting pst->texthigh.
595
596 Fri Oct 4 16:47:32 1991 Roland H. Pesch (pesch at cygnus.com)
597
598 * doc/Makefile: make TEXINPUTS include . everywhere
599
600 Fri Oct 4 00:35:56 1991 John Gilmore (gnu at cygnus.com)
601
602 * coffread.c, dbxread.c, symfile.c, symmisc.c, symtab.h: Remove
603 vestiges of typevectors, which were for symsegs and are no longer
604 used. (From a question by Eliot Dresselhaus
605 <dresselh@RFT30.nas.nasa.gov>).
606
607 Thu Oct 3 09:33:26 1991 John Gilmore (gnu at cygnus.com)
608
609 * dbxread.c, coffread.c: static-ize functions that were
610 gratuitiously external. (From Fred Fish.)
611
612 * c-exp.y: sym->class to SYMBOL_CLASS (sym).
613
614 * dbxread.c (dbx_lookup_type): Keep doubling size of typevector
615 until it is large enough.
616
617 * dbxread.c (read_type): Handle error case slightly better.
618 Make complaint message not C++-specific.
619
620 Wed Oct 2 17:21:07 1991 Stu Grossman (grossman at cygnus.com)
621
622 * infrun.c (wait_for_inferior): Fix step/next so that you only
623 stop at the beginning of a new line. This fixes various problems
624 with for loops, nested if-else's and switch statements.
625
626 Tue Oct 1 06:33:55 1991 John Gilmore (gnu at cygnus.com)
627
628 * symtab.c (lookup_symtab_1, lookup_symbol): "fatal" errors
629 between symtabs and psymtabs become ordinary error()s.
630
631 * dbxread.c (read_dbx_symtab): Relocate end_of_text_addr
632 properly, making "end pc" correct in shared lib psymtabs.
633 (From Guy Harris <guy@auspex.com>.)
634
635 Mon Sep 30 13:15:31 1991 John Gilmore (gnu at cygnus.com)
636
637 * dbxread.c: Enable, but soften, const_vol_complaint.
638 (read_dbx_symtab): N_STSYM and N_LCSYM define static vars.
639 Ditto Gould N_NBSTS and N_NBLCS. Also, all types in the psymtab
640 should be file-scope, not global.
641 (read_struct_type): Remove ancient multiple-inheritance warning.
642 (read_range_type): Check base type, complain & patch if undefined.
643 * stack.c (frame_info): Demangle the function name in `info stack'.
644 (From Peter Schauer)
645
646 Sat Sep 28 10:02:33 1991 John Gilmore (gnu at cygnus.com)
647
648 * eval.c (evaluate_subexp_for_address): Don't use
649 TYPE_POINTER_TYPE directly (it might be zero if this type has
650 never had a pointer created before); use lookup_pointer_type.
651 * symtab.c (lookup_method_type): Arguments were swapped in all
652 callers, so fix it here. I'm amazed this worked at all!
653
654 Fri Sep 27 18:09:31 1991 John Gilmore (gnu at cygnus.com)
655
656 * c-exp.y, m2-exp.y: Define more yysymbols that happen to be
657 "bss" rather than "data" symbols, but which still conflict.
658 * m2-exp.y: Lint.
659
660 * coffread.c (coff_symfile_read): Use xmalloc, not malloc.
661 * core.c (core_files_info): Shorten output.
662 * exec.c (exec_files_info): Ditto.
663 (build_section_table): Ignore zero-length sections.
664 * language.c, printcmd.c: Lint.
665 * language.h (get_frame_language): Declare.
666 * saber.suppress: update.
667 * stack.c (find_relative_frame): Remove complex code that was
668 #if 0'd, stick with simple code. Lint.
669 * saber.suppress: Update a bit.
670 * symfile.c (add_symbol_file_command): Add "?" to question.
671 * utils.c (parse_escape): Avoid \a due to bdead compilers.
672 * value.h: Declare typedef_print.
673
674 * valprint.c (val_print, type_print_base): TYPE_CODE_RANGE less
675 kludgey.
676
677 * nindy-tdep.c (nindy_frame_chain_valid): Use lookup_misc_func.
678 (Reported by Mark Peek <mark@imagen.com>.)
679
680 * solib.c (solib_map_sections): Relocate all sections, even
681 though only the text section's size is tracked. Mark ld_text
682 for eventual elimination as we generalize to N sections.
683
684 * infrun.c (wait_for_inferior): Don't check if the PC is in a
685 call_dummy if we were stopped by a random signal that is being
686 passed to the program. This produced wierd results when calling
687 functions in the inferior and signals (e.g. SIGALRM) were in use.
688
689 Tue Sep 24 18:05:30 1991 John Gilmore (gnu at cygnus.com)
690
691 * infrun.c (IN_SIGTRAMP): Not parenthesized properly.
692 Bugfix from Paul Eggert <eggert@twinsun.com>.
693 * tm-ultra3.h (IN_SIGTRAMP): Ditto.
694 * valprint.c (print_floating): Print 9 digits for IEEE floats.
695 From Paul Eggert.
696
697 Mon Sep 23 15:50:07 1991 John Gilmore (gnu at cygnus.com)
698
699 * Makefile.in: Roll VERSION to 4.1.1.
700 * source.c (line_info): Peter Schauer fixes a bug I introduced in
701 hex conversion.
702
703 Fri Sep 20 16:10:52 1991 John Gilmore (gnu at cygnus.com)
704
705 GDB-4.1 release!
706
707 * Makefile.in (VERSION): Set to 4.1.
708 * language.c (set_language_command): Print useful help message,
709 and restore the language string after giving help.
710 * valprint.c (typedef_print): Print typedef in C or M2.
711 * symtab.c (list_symbols): Use it.
712 * main.c (main): Avoid any output before (gdb) prompt when -q.
713 * language.c (set_language_command): Handle errors by restoring
714 the language string to its current state (fix from A. Beers).
715 * doc/gdbint.texinfo: Roll in information from README. Rearrange
716 "how to install" and "how to print the doc" stuff so it drops
717 easier into README.
718 * configure.in: Rename rtpc CPU to romp to match config.sub.
719 * README, WHATS.NEW, TODO: Update for gdb-4.1.
720

722
723 * doc/gdb.texinfo: Updates from ChangeLog. set/show write,
724 autoloading shared libs, copyright etc on GDB startup, clean up $_
725 and $__ index refs, set/show listsize and related updates to list
726 cmd. New host/target configs.
727
728 Fri Sep 20 15:46:00 1991 Roland H. Pesch (pesch at cygnus.com)
729
730 * doc/Makefile: generate aux version-no file doc/gdbVN.m4
731 from main Makefile.in version definition
732 doc/gdb.texinfo: use version recorded in doc/gdbVN.m4 for current
733 GDB version no refs
734 Makefile.in (setup-to-dist): generate doc/gdbVN.m4
735
736 * doc/gdb.texinfo: merge new language-switching and lang-specific
737 doc by Andrew Beers
738
739 Fri Sep 20 15:00:57 1991 Per Bothner (bothner at cygnus.com)
740
741 * mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
742 compilers (which may lack stddef.h).
743
744 Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com)
745
746 * dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and
747 N_WARNING are the same except for the N_EXT bit, so just use their
748 values alone, rather than OR-ing them with N_EXT.
749
750 Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com)
751
752 * mipsread.c (parse_lines): Deal with negative extended line
753 offsets correctly.
754
755 * c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid
756 global symbol conflicts.
757
758 Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
759
760 * .gdbinit: Move 'set complaints' to top, so it runs even in
761 case we aren't debugging GDB.
762 * language.c (_initialize_language): Fix type check and range
763 check documentation strings.
764 * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
765 language.c can use it. (Though language.c should really not be
766 handling warnings/errors the way it does, FIXME.)
767 * symtab.c (lookup_primitive_type): const lint.
768
769 Bugfix from Peter Schauer:
770 * source.c (lines_to_list): Make signed, to avoid comparison
771 going unsigned and complaining that -3 is too high for 21 lines.
772 * stack.c (lines_to_list): Ditto.
773
774 Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
775
776 * Makefile.in (HFILES): Add minimon.h.
777 (VERSION): Roll version number to 4.0.95.
778 (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
779 New rules for building distributions. Normal distribution
780 is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
781 one level up from here; it calls make-proto-gdb.dir to build a
782 directory `proto-gdb' which is an image of the release. The old
783 `gdb.tar.Z' rule still works too.
784 * config.sub, configure: Roll in latest from ..
785
786 Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
787
788 * doc/gdbint.texinfo: Reorder contents; reorganize new-host,
789 new-target, and new-config chapters; fix minor typos; come closer
790 to usual GNU markup conventions for @file @samp @code @var.
791
792 Thu Sep 19 17:04:12 1991 Per Bothner (bothner at cygnus.com)
793
794 Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
795 * mipsread.c (parse_partial_symbols): Enter the name of all
796 structs/unions... into the psymtab so we can access them if the
797 symtab is not read in.
798 * mips-tdep.c: Remove some unneeded #includes.
799 * xconfig/dec3100: Add HAVE_STRSTR.
800
801 Thu Sep 19 15:14:23 1991 John Gilmore (gnu at cygnus.com)
802
803 * Makefile.in: Circumvent Sun Make bug on *-exp.tab.o.
804 * c-exp.y, m2-exp.y: Lint.
805 * m2-exp.y: Avoid using yytname[] which is a Bison-ism.
806 * valprint.c (val_print_fields): Check for stub type.
807 * mipsread.c (_initialize_mipsread): Avoid using
808 builtin_type_void at initialize time.
809 (mipscoff_symfile_read): use it now.
810
811 Wed Sep 18 15:55:51 1991 John Gilmore (gnu at cygnus.com)
812
813 Merge multiple-language support, and partial Modula-2 support,
814 from Andrew Beers <beers@cs.buffalo.edu>.

819 * xconfig/i386{sco,v,v-g,v32,v32-g}: Now need i387-tdep.o.
820
821 * symfile.c (allocate_symtab): New fn, consolidates the work
822 of allocating and initializing a new struct symtab. Set the
823 language of the symtab based on its filename extension.
824 * symfile.h: Declare it.
825 * mipsread.c (new_symtab): Use it. Minor formatting changes.
826 * dbxread.c (end_symtab): Use it.
827
828 * mipsread.c (parse_symbol, case stParam and stProc): Add #if 0'd
829 code for saving types of parameters with each function definition.
830 * dbxread.c (define_symbol, function and parameter cases): Ditto.
831 (read_dbx_symtab, case N_DEFD): Ignore.

844 i387-tdep.c, infcmd.c, mips-tdep.c, stack.c, printcmd.c: Output
845 hex with local_hex_string for Modula-2 support.
846
847 * breakpoint.c (breakpoint_cond_eval): Use new value_true to test
848 breakpoint condition language-independently.
849
850 * parse.c: New file with the common code remains of expread.y.
851 * parser-defs.h: New file with common declarations from expread.y.

857 parse_expression and parse_exp_1 rather than parse_c_expression
858 and parse_c_1.
859
860 * symtab.h (enum languages): Move to defs.h.
861 (enum type_code): Add TYPE_CODE_CHAR and TYPE_CODE_BOOL.
862 Declare Modula-2 builtin types.
863 Add MAX_OF_TYPE and MIN_OF_TYPE macros.
864
865 * symtab.c (_initialize_symtab): Remove builtin type
866 definition and initialization to *-exp.y.
867 (lookup_primitive_typename): Use language-dependent vector.
868 (lookup_typename): Fix bug, make it work if primitive typename.
869 (lookup_unsigned_typename): Call above.
870 (create_array_type): Set up range type for array index.
871 (list_symbols): Call typedef_print to print typedefs.
872
873 * values.c (unpack_long, value_from_longest): Handle
874 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
875
876 * expression.h (enum exp_opcode): Add Modula-2 specific opcodes.
877 * expprint.c: Look up expression opcodes in language-specific
878 table, based on expression's language. Handle some Modula-2
879 specific opcodes.
880
881 * stack.c (frame_info): Print language of stack frame.
882 (select_frame): Also select language, if in auto-mode.
883 (get_frame_language): New subroutine.
884 * main.c (execute_command): Warn as language changes automatically.
885
886 * printcmd.c (ptype_command): Parse types using the language
887 parser, both for language-independence, and so that scopes can
888 be specified.
889
890 * language.h, language.c: New files for language-specific macros,
891 declarations, and definitions.
892
893 Misc fixes:
894
895 * main.c (main): If error() is called during early
896 initialization, print its message and then exit(1) from GDB.
897
898 * valprint.c (type_print_base): Avoid printing garbage for ints
899 of unusual sizes.
900 (_initialize_valprint): Warn about host/target size assumption;
901 improve long long support slightly.
902
903 * convex-tdep.c (comm_registers_info): Avoid parsing decimal and

905
906 * doc/gdbint.texinfo (Languages): Doc how to add a language.
907
908 * Makefile.in: Cope with new files and removed files.
909
910 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
911
912 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
913 entries are enclosed herein. Not all of these changes
914 have been merged into the master GDB sources -- check the
915 ChangeLog above here for the merge log.
916
917 Mon Jun 3 17:05:45 EDT 1991
918
919 m2-exp.y Created. Tested outside of GDB for a few days. Proper
920 operators were added, C specific operators and tokens
921 removed. yylex() revamped to some extent. Still things
922 missing from the grammar, such as sets.
923 Tested for two weeks in GDB v3.5.
924
925 Tue Jun 11 17:23:48 EDT 1991
926
927 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
928 so they are built-in. Sort of a hack.
929
930 Fri Jun 14 12:53:51 EDT 1991
931
932 m2-exp.y Added range checking for numeric constants. Any numeric
933 constant is assumed to be of builtin type INTEGER unless:
934 (1) it is octal or hexadecimal, in which case it is a
935 CARDINAL; (2) it is too big to fit into an INTEGER, in
936 which case it is a CARDINAL.
937 eval.c Added simple range checking for +, -, and * on integers.
938 Doesn't work very well for *, since 6 * 1,000,000,000 =
939 1,705,032,704, which fails the simple test of result >=
940 first_operand, no matter in what order the operands are.
941
942 Tue Jun 18 14:11:30 EDT 1991
943
944 Broke the parser into parts, one containing the C grammar and the other
945 containing code to be shared by all of the grammars.
946
947 The following files no longer exist:
948
949 expread.y
950 expread.tab.c
951
952 The following files were added:
953
954 c-exp.y (The C grammar)
955 m2-exp.y (The Modula-2 grammar)
956 parser-code.c (Code that is shared by the above grammar)
957 parser-code.h
958 parser-defs.h
959
960 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
961 now necessary to use the Bison compiler compiler, since it
962 will generate function/variable prefixes other than yy.
963
964 Tue Jun 18 16:47:49 EDT 1991
965
966 symtab.[ch] Added the external variable working_lang, than holds the
967 value of the current working language.
968 Added the ennumerated type language_mode, with the values
969 language_auto and language_manual, the former meaning that
970 GDB sets working_lang as needed, and the latter meaning
971 that the value of working_lang is totally under user
972 control.
973 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
974 REAL, BOOLEAN and CHAR. Also added the type codes
975 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
976 utils.c Added set_language_command and show_language_command to
977 implement the GDB support commands "set language" and
978 "show language".
979 expression.h A number of identifiers were added to the type exp_opcode
980 to facilitate Modula-2 builtin functions, integer
981 division, and array indexing.
982
983 Wed Jun 19 13:25:58 EDT 1991
984
985 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
986 if the language specified by working_lang requires the use
987 of strict typing of expressions. Eventually, even this
988 will be able to be changed by the user.
989 Added the macro RANGE_CHECK, which evaluates to non-zero
990 if the language specified by working_lang requires the
991 checking of a value against the domain of its type.
992 Eventually, even this will be able to be changed by the
993 user.
994 language.[ch] Predicates involving types (simple_type, ordered_type,
995 same_type, integral_type, numeric_type, character_type,
996 boolean_type, float_type) are added. These predicates are
997 based on the current value of working_lang, and are handy
998 in type-checking.
999
1000 Wed Jun 19 15:39:34 EDT 1991
1001
1002 eval.c Added the function type_array_rank which computes the rank
1003 of an array type.
1004 valarith.c Added the funtion value_bool, which when given a integer
1005 value.h value (ie. struct value *) as an argument, it returns a
1006 boolean value (ie. struct value *) true if that integer
1007 is non-zero, and a boolean value false otherwise.
1008 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
1009 will print out properly.
1010
1011 Wed Jun 19 16:36:34 EDT 1991
1012
1013 valops.c Added the function value_capitalize, which returns it
1014 value.h argument capitalized if its argument is a lowercase
1015 letter, or the argument unchanged if its argument is not a
1016 letter.
1017 valarith.c Added the function range_check_p, which returns non-zero
1018 value.h if its value argument is between the integral bounds upper
1019 and lower.
1020 Added the function range_check_enum_p, which makes sure
1021 that its value argument is a valid member of the domain of
1022 its type argument.
1023 Added the function range_check_range_p, which makes sure
1024 its value argument lies between the upper and lower bounds
1025 of its type argument, which must be a ranged type.
1026 Added the function check_array_index, which range and type
1027 checks an index of an array.
1028 Added the function value_multi_subscript, which computes
1029 array[idx1,idx2...idxN], given a value array and an array
1030 of values representing indicies.
1031 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
1032 unpack_long to work with TYPE_CODE_BOOL and
1033 TYPE_CODE_CHAR.
1034
1035 Wed Jun 19 18:04:08 EDT 1991
1036
1037 symtab.c Stored pervasive types in a structure and make
1038 lookup_pervasive_type() a lookup function that was based
1039 on working_lang. If lookup_pervasive_type() returned
1040 non-zero, then that value was returned (a fix, since
1041 before it simply wouldn't return the pervasive type.)
1042 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
1043 non-zero if the language specified by working_lang means
1044 "conversion" when it says "cast".
1045 valops.c Added the function value_real_cast(), which performs a
1046 value.h *cast*, not a *conversion*, which is what value_cast()
1047 does when it can. In particular,
1048 value_cast(<float_type>,4) = 4.0, while
1049 value_real_cast(<float_type>,4) = some mess.
1050 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
1051 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
1052 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
1053 and MIN on integral types. *NOTE*: These are currently
1054 hardcoded to work only if there are 8 bits per storage
1055 unit. FIXME.
1056 eval.c Made logical functions call value_bool to return a
1057 properly typed boolean value, based on working_lang.
1058
1059 Thu Jun 20 11:55:27 EDT 1991
1060
1061 valprint.c Types now print out in a Modula-2 fashion. This works for
1062 the cases when the type is printed out step-by-step, that
1063 is, it doesn't work when the name of a structured type
1064 (which includes the keyword "struct", etc.) is simply
1065 displayed.
1066 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
1067 since type specifications in C and Modula-2 are very
1068 different. The C printing of a type is very recursive,
1069 whereas in Modula-2 it is generally very simple. C has
1070 type prefixes and suffixes, which have no real analogue in
1071 Modula-2. Maybe type_print() should call a language
1072 specific type printer. This is also advantageous if we
1073 compile GDB to exclude some of the languages. We'll just
1074 leave those functions out.
1075
1076 Thu Jun 20 16:57:10 EDT 1991
1077
1078 dbxread.c When reading the complete symbol table in (via
1079 psymtab_to_symtab()), the number and types of function
1080 arguments are added to a function type. define_symbol()
1081 calls add_param_to_type() to accomplish this.
1082 Assumption: when we come across a function definition
1083 (N_FUN symbol with an 'f' or 'F' in the name), its
1084 arguments will appear before another function definition.
1085 When a function is found, a pointer to its type is placed
1086 in the global in_function_type. Changes that
1087 add_param_to_type() makes are to this global.
1088 valprint.c The type of a function now includes (for Modula-2) the
1089 types of its parameters.
1090 eval.c Type checking and a check for the proper number of
1091 arguments is now done for function calls. Not sure of the
1092 impact this has on C++ member function yet.
1093
1094 Thu Jun 20 19:58:48 EDT 1991
1095
1096 valprint.c Rewrote the type printer. Broke it into two language
1097 specific parts, adding the functions type_print_m2() and
1098 type_print_m2_1().
1099 An unfortunate consequence is this: if you debugging a C
1100 program in Modula-2 mode (why?), info types does not work
1101 well with regular expressions, since the types are printed
1102 out in Modula-2 terminology, but stored in C terminology.
1103 language.[ch] Added the functions new_type_last(), type_keyword(), and
1104 type_sep() to aid in the printing of typedefs.
1105 symtab.c Made the printing of typedefs as language independent as
1106 possible through calls to new_type_last(), type_keyword(),
1107 and type_sep().
1108
1109 Fri Jun 21 11:50:26 EDT 1991
1110
1111 dbxread.c Check all incoming ennumerated types. If it looks like
1112 Modula-2's BOOLEAN type, then change the type_code of the
1113 type to TYPE_CODE_BOOL so we can process it as a boolean
1114 variable.
1115 valprint.c Replaced some of the 0x%x with calls to sprintf and
1116 hexformat() in val_print().
1117 language.[ch] Added the function hex_to_string(), which converts its
1118 integral argument to a hexadecimal number (format is
1119 language based) and returns the result as a string.
1120
1121 Mon Jun 24 12:25:07 EDT 1991
1122
1123 valprint.c Some functions call type_print_1() directly, instead of
1124 value.h using type_print(), so they can specify where (column) to
1125 print things. Since type_print() takes care of language
1126 dependence, that needs to be called first. Added a
1127 parameter depth to type_print() (so it is now like
1128 type_print_1). Changed type_print to type_print_at, and
1129 made type_print a macro that passes a depth argument of
1130 zero.
1131 symmisc.c Changed all calls to type_print_1 to calls to
1132 type_print_at.
1133 Makefile.dist Made it possible to build GDB for a specific set of
1134 depend languages. Do this by passing a definition for the macro
1135 LANGS to make. LANGS should be a string containing a
1136 space-separated list of language names (ie. LANGS="c m2").
1137 The default is to build all languages. Note that grammar
1138 files must follow the naming convention of <lang>-exp.y.
1139 gdb.lang This holds the current value of the LANGS macro. It is
1140 examined every time make is called, and is updated if
1141 necessary.
1142 eval.c Added #ifdef _LANG_<lang> to these files.
1143 expread.c Still need to add them to dbxread.c and coffread.c.
1144 main.c
1145 source.c
1146 symtab.c
1147 utils.c
1148 valarith.c
1149 valprint.c
1150
1151 Mon Jun 24 16:33:11 EDT 1991
1152
1153 language.[ch] Added the functions hexformat_pre() and
1154 hex_to_string_pre(), which take a prefix argument to
1155 include in the format string. Thus, hexformat_pre("08") will
1156 return "0x08x" (if the working language is language_c).
1157 Made hexformat() and hex_to_string() calls to the above
1158 with "" as the prefix argument.
1159
1160 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
1161 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
1162 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
1163 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
1164 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
1165 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
1166 valprint.c, vax-pinsn.c
1167
1168 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
1169 calls to hexformat() and hex_to_string(). Format strings without
1170 the leading "0x" were ignored.
1171
1172 depend Updated to take the above into account.
1173
1174
1175 Tue Jun 25 15:27:18 EDT 1991
1176
1177 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
1178 and type_check_t to keep track of the current state of
1179 range and type checking.
1180 main.c Added the variables range_mode, range_check, type_mode,
1181 and type_check to record the current state of range and
1182 type checking. Added initialization code to main().
1183 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
1184 the above variables.
1185
1186
1187 Tue Jun 25 17:57:08 EDT 1991
1188
1189 dbxread.c process_one_symbol() updates the variable (enum language)
1190 source_lang based on the extension of the filename
1191 contained in the N_SO sybmol that started this symtab.
1192 When end_symtab() is called, the value of source_lang is
1193 put into the language field.
1194 stack.c select_frame() sets working_lang (and possibly type_check
1195 and range_check) to the language field of the symtab
1196 associated with the frame that is selected if working_mode
1197 is language_auto. If working_mode is language_manual, a
1198 warning is printed and working_lang is not set.
1199 language.c Added the function set_type_range(), which sets the value of
1200 type_check and range_check (if their modes call for
1201 automatic setting) based on the current value of
1202 working_lang. A non-zero argument will cause the current
1203 settings to be output.
1204
1205
1206 Wed Jun 26 14:51:40 EDT 1991
1207
1208 eval.c Added range checks on assignment.
1209 m2-exp.y Added the grammar for sets to the language. Currently,
1210 these do not do anything except print an error message.
1211
1212 Wed Jun 26 17:01:04 EDT 1991
1213
1214 m2-exp.y Added the ability for parse_number() to parse negative
1215 numbers. A global flag is set upon encountering a unary
1216 minus. This was done to make, for example, 1 parse as a
1217 CARDINAL, and not as an integer, per Wirth's examples in
1218 Programming in Modula-2 ed.4.
1219 valprint.c Added support for "set radix 2" by then setting
1220 output_format to 't'.
1221 eval.c Implemented range checking on subrange types. Added calls
1222 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
1223 Implemented MIN and MAX for ennumerated types. The
1224 minimum value of an ennumerated type is defined by Wirth
1225 as the first identifier, and the maximum as the last.
1226 m2-exp.y Made octal numbers ending with "B" be characters and those
1227 ending with "C" be numbers, per Wirth's book. (p. 34)
1228
1229 Thu Jun 27 14:11:52 EDT 1991
1230
1231 stack.c select_frame() now only sets working_lang, it does not
1232 notify the user. If working_mode is language_manual, then
1233 a warning is issued once.
1234 main.c At the end of each call to execute_command(), working_lang
1235 is checked against the local static (enum language)
1236 current. If they differ and working_mode is
1237 language_auto, the new settings of language, type and
1238 range checking are printed out.
1239 stack.c Modified frame_info() to include the language of the
1240 current frame in the output of "info frame".
1241 language.[ch] Added the function language_str() which returns the name
1242 of the current language.
1243
1244 Fri Jun 28 15:33:14 EDT 1991
1245
1246 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
1247 the language. INCL and DECL currently cause an error,
1248 since sets are not implemented yet. INC and DEC are
1249 implemented as PREINCREMENT/PREDECREMENT with one
1250 argument, and as ASSIGN_MODIFY with two arguments.
1251 eval.c Added type checking to the above cases.
1252 value.h Added not_lval_constant to the lval_type ennumerated type.
1253 not_lval_constant means that the value is a constant
1254 value; that is 3 or 'a' or TRUE, not as in a constant
1255 identifier. This is used to help coerce numbers such as 3
1256 to either signed or unsigned numbers.
1257 valops.c Added the function value_coerce_constants() which coerces
1258 constant integers as following: if one is a constant and
1259 the other is not, the constant's type is set to the type
1260 of the other argument. If both are constants and one is
1261 signed, the other is converted to a signed constant.
1262
1263 Sat Jun 29 17:26:29 EDT 1991
1264
1265 valarith.c Added a better range checker. It now checks range
1266 (successfully) on integral operations [+-] (signed and
1267 unsigned) for any C sized type. Still does not work well
1268 for multiplication.)
1269 int_in_size() returns an integer that is coerced to fit into
1270 specified number of bytes.
1271
1272 Mon Jul 1 13:04:14 EDT 1991
1273
1274 language.[ch] Added the function binop_result_type(), which returns the
1275 builtin (struct type *) type that would be the result of a
1276 binop on the two values V1 and V2.
1277
1278 Wed Jul 3 19:22:53 EDT 1991
1279
1280 source.c Extended source_info() to include the source language in
1281 the output from "info source".
1282
1283 Fri Jul 5 13:48:52 EDT 1991
1284
1285 utils.c Moved the support functions for the GDB set/show commands
1286 dealing with language into language.c.
1287 language.c Added the function language_info(), which displays info
1288 about the current working language, type and range check
1289 settings. Called via the GDB command "info language".
1290 Added an initialization routine _initialize_language(),
1291 that sets defaults for the language, type and range
1292 variables and sets up the new GDB commands.
1293 main.c Language setup moved to language.c.
1294 depend Rebuilt.
1295
1296 Mon Jul 8 10:10:22 EDT 1991
1297
1298 valarith.c Debugged the range checker for arithmetic. Still does not
1299 work for multiplication very well.
1300
1301 Mon Jul 8 12:40:37 EDT 1991
1302
1303 language.[ch] Added the function value_true() which returns non-zero if
1304 its argument represents a boolean true value.
1305 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
1306 check the truth of an expression.
1307
1308 Thu Jul 11 12:51:34 EDT 1991
1309
1310 language.[ch] Added the predicate structured_type(), which returns
1311 non-zero if the argument is a structured type.
1312 Added the predicate pointer_type(), which returns non-zero
1313 if the argument is a pointer type.
1314 eval.c Added the ability to do addition and substraction on
1315 pointers and integers. This case simply bypasses the
1316 type checker.
1317
1318 Thu Jul 11 14:41:42 EDT 1991
1319
1320 include/stab.def
1321 Added the symbol N_DEFD (0x4a) which is a definition
1322 module dependency that is used by the GNU Modula-2
1323 compiler and the linker. It is not important to GDB,
1324 except that [dbx|coff|mips]read.c should ignore these
1325 symbols.
1326
1327 Fri Jul 12 16:07:00 EDT 1991
1328
1329 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
1330 0 in val_print(). Also added statements to the else part
1331 to coerce type (argument to val_print) to a pointer type
1332 if it is an "array of unspecified length".
1333 valops.c Added the function value_m2_string(), which returns a
1334 (value) value which is a constant string, whose type is
1335 (ARRAY [0..n] OF CHAR). The length field of the type
1336 structure is set to zero, so it will be interpreted as an
1337 "array of unspecified length".
1338 stack.c Moved the language/frame mismatch check to
1339 main.c:execute_command().
1340 main.c The working language is recorded each time
1341 execute_command() is executed. If working lang has
1342 changed during its execution, then the new
1343 language/type/range info is printed out for the user. If
1344 the working language does not match the language of the
1345 frame, a warning is issued.
1346
1347 Sat Jul 13 16:16:39 EDT 1991
1348
1349 eval.c Moved all the type-checking stuff for operators to
1350 language.[ch] language.c. This is so we can keep language-specific
1351 stuff (like for what type operators are defined) in
1352 language.c.
1353 language.[ch] Added the function binop_type_check(), which checks to see
1354 if its two (value) arguments are type-compatible with its
1355 opcode argument. The opcode should represent an operation
1356 involving an operator. Also added the macro function
1357 unop_type_check, which calls binop_type_check with a
1358 NULL second argument.
1359 expprint.c Added Modula-2 operators to the op_print_tab, so info
1360 expression.h break works correctly. Also added "op_string", which
1361 returns the string corresponding to the (enum exp_opcode)
1362 opcode that is its argument.
1363
1364
1365 Sat Jul 13 18:26:18 EDT 1991
1366
1367 coffread.c Added code to record the type of function arguments with
1368 each paricular function. Code is very similar to that
1369 added to dbxread.c.
1370 dbxread.c Moved add_param_to_type() to symtab.c
1371 symtab.[ch] Added function add_param_to_type() from dbxread.c
1372
1373 *** NOTE: The above additions have not been tested.
1374
1375 Mon Jul 15 12:50:47 EDT 1991
1376
1377 langauge.[ch] Added the functions type_error and range_error, which work
1378 like error() except if the type/range mode is set to
1379 *_mode_warn, then they do not do a return_to_top_level(),
1380 but merely print a warning.
1381 Also changed [set|show]_[type|range]_command() to support
1382 the new "warn" feature.
1383
1384 Thu Jul 18 17:50:54 EDT 1991
1385
1386 mipsread.c Added code to record the type of function arguments with
1387 each particular function. Code is very similar to that
1388 added to dbxread.c.
1389
1390 *** NOTE: The above additions have not been tested.
1391
1392 Fri Jul 19 11:19:10 EDT 1991
1393
1394 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
1395 UMIN_OF_SIZE, which when given a size of a numeric type,
1396 return the maximum and minimum value it can hold. UMAX...
1397 and UMIN... return the result for unsigned types.
1398 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
1399 struct types. They call above macros.
1400 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
1401 avoid a name conlict with the above.
1402 c-exp.y Added range checking on numeric constants in
1403 parse_number() for completeness.
1404 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
1405 return 0 if working_lang is not language_c.
1406
1407 Thu Aug 8 14:17:22 EDT 1991
1408
1409 main.c
1410 printcmd.c
1411 breakpoint.c Documentation strings of some commands changed to
1412 eliminate the references to the C language where
1413 appropriate.
1414
1415 Tue Aug 13 15:48:03 EDT 1991
1416
1417 m2-exp.y Added qualified identifiers to the grammar. The semantics
1418 are slightly different from those of the GDB operator ::
1419 c-exp.y
1420 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
1421 type_exp, where type_exp is any valid type expression.
1422 expression.h
1423 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
1424 printcmd.c Modified ptype_command() so it actually parses the input
1425 (necessary for type expressions with scope qualifiers).
1426 Added the function ptype_eval() which expects an
1427 expression composed of one OP_TYPE element.
1428 *.[ch] Replaced all occurences of parse_c_expression with
1429 parse_expression
1430 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
1431
1432 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]

1434 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
1435
1436 Small fixes from Peter Schauer:
1437
1438 * infrun.c (child_attach): Lint.
1439 * solib.c (find_solib): Handle shared libs version 2.
1440
1441 Small fixes from David Wood:
1442
1443 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
1444
1445 Small fixes:
1446
1447 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
1448 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
1449
1450 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
1451 chars_per_line is at maximum (user typed `set width 0'). Fix
1452 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
1453
1454 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
1455
1456 * coredep.c: include ptrace.h where necessary.
1457 * mipsread.c(parse_lines): fix unsigned char problem that was
1458 messing up line numbers on SGI's and possibly other MIPS based
1459 platforms.
1460 * infrun.c (child_create_inferior): use better test to check
1461 return val from setpgrp().
1462 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
1463 for sgi/irix support.
1464
1465 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
1466
1467 * mipsread.c (parse_symbol): Put non-static procedures
1468 in the global block.
1469
1470 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
1471
1472 Patch together `text_start' and `text_end' for 29K port.
1473
1474 * exec.c (exec_command): If NEED_TEXT_START_END, define the
1475 variables and set them based on the exec file.
1476 * am29k-tdep.c: declare text_start.
1477 * valops.c (call_function_by_hand): declare text_end.
1478
1479 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
1480 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
1481 because machines that do this will also have to know to
1482 set NEED_TEXT_START_END. Besides, it was a redundant way to
1483 say the same thing.
1484 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
1485 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
1486 NEED_TEXT_START_END.
1487
1488 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
1489
1490 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
1491
1492 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
1493 Pass MUNCH_DEFINE to munch whenever we run it.
1494 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
1495 format string; use 0x%x instead.
1496 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
1497 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
1498 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
1499 * inflow.c: Handle `short' process group IDs.
1500 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
1501 and check for ptrace errors.
1502 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
1503 (coff_symfile_init): Initialize text_bfd_scnum.
1504 (read_coff_symtab): Use it to find the text [and absolute?] sections.
1505 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
1506 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
1507 Merge target arm case with other "easy" cases. Add target
1508 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
1509 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
1510 process).
1511 * minimon.h, remote-adapt.c, remote-mm.c: Add.
1512 * munch: Cope with RT/PC putting fns in data segment.
1513 Restore ability to override `nm' by specifying MUNCH_NM.
1514 * xconfig/rtbsd, xconfig/ultra3: New host systems.
1515 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
1516 and remote-adapt. Remove encapsulated coff #define's (the
1517 support should go in BFD, and gdb shouldn't know or care).
1518 * tconfig/a29k-kern: Same, but for remote kernel debugging.
1519 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
1520 * tm-29k.h: Update BADMAG (though it should go away).
1521 Allow the register definitions to be overridden in another
1522 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
1523 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
1524 DUMMY_SAVE_GR96, for handling kernel calling conventions
1525 that use GR64+ rather than GR96+.
1526 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
1527 remote debugging of Ultra3 kernel. Includes tm-29k.h and
1528 overrides various things.
1529
1530 * remote-mm.c (mm_attach, mm_wait): Handle attach like
1531 child_attach does, making a clean stop in the newly attached
1532 program.
1533 * remote-eb.c: Lint.
1534
1535 * coffread.c: Make coffread independent of any particular
1536 variant of COFF. Avoid #include-ing any particular one except
1537 internalcoff.h. BFD now passes key values for symbol reading
1538 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
1539 and the symbol masks and shifts); use them.
1540 Remove obsolete end_of_text_addr.
1541
1542 * exec.c: Remove unused include files.
1543
1544 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1545
1546 * Makefile.in (documentation targets): Pass $(M4).
1547 Bugfix from eggert@twinsun.com (Paul Eggert).
1548
1549 * stack.c (down_silently_command): Check for stack existence.
1550
1551 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1552
1553 * Makefile.in (VERSION): Update to 4.0.3.
1554
1555 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1556
1557 * core.c (core_file_command): Print frame at coredump with
1558 its level number, by calling print_stack_frame.
1559 * frame.h: Add selected_frame_level, print_stack_frame.
1560 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
1561 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
1562 Change print_sel_frame and print_selected_frame callers to
1563 print_stack_frame.
1564
1565 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
1566 * symfile.c (free_named_symtabs): Ditto.
1567 * main.c (main): wrap_here needs an arg.
1568 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
1569 (solib_add): Avoid noise.
1570 (solib_create_inferior_hook): Lint.
1571 (sharedlibrary_command): Move dont_repeat to here.
1572 * utils.c (error): Call wrap_here to force buffered output.
1573
1574 Small patches from Peter Schauer:
1575
1576 * coffread.c (start_symtab): Free any existing line_vector before
1577 malloc-ing new one.
1578 (read_coff_symtab): Ditto for type_vector.
1579
1580 * source.c (lines_to_list): New variable, replacing function.
1581 (all uses): Use as variable.
1582 (_initialize_source): Add 'set listsize' and 'show listsize'.
1583 * utils.c (lines_to_list): Remove function.
1584 * stack.c (print_frame_info): Use as variable.
1585 * defs.h (lines_to_list): Remove declaration.
1586
1587 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1588
1589 * breakpoint.c (insert_breakpoints): Restore warning about
1590 the program might be running in another process, but only for
1591 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
1592 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
1593
1594 * utils.c (error): if error_pre_print is set, print the string
1595 first.
1596 * main.c (main, print_gnu_advertisement, print_gdb_version):
1597 Reformat legalese so it always prints, but acts as an "I'm here"
1598 message while symbols are being read. If any errors occur,
1599 print a few newlines to set off the message and start it at the
1600 left margin. Remove mention of "help" command, and don't yak
1601 about symbol reading.
1602 (catch_errors): Error string is now printed first in case of
1603 error, not last.
1604 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
1605 suggest the "help" command.
1606
1607 * Makefile.in (VERSION): Set to 4.0.2.
1608
1609 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
1610
1611 * .gdbinit: Remove useless "rr" command. Set complaints
1612 to 1 for people debugging gdb.
1613
1614 * breakpoint.c, remote-vx.c: Reword strings printed by
1615 catch_errors callers.
1616
1617 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
1618
1619 * WHATS.NEW: "history write -> history save". Doc "write on/off".
1620 (Fix from kenc@viewlogic.com.)
1621
1622 Fix some infrastructure to be able to cope with host and target
1623 machines with different sized basic types (ints, ptrs, etc).
1624 (Idea from pierre@la.tce.com (Pierre Willard).)
1625
1626 * values.c (value_from_longest): Rename from value_from_long.
1627 Handle pointer types as well as integers, so that targets with
1628 different pointer sizes from the host can be accomodated.
1629 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
1630 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
1631 uses of value_from_long to value_from_longest.
1632 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
1633 the correct pointer type to value_from_long{est}.
1634
1635 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
1636
1637 * remote-vx.c: Remove obsolete code for calling functions via
1638 vxworks kludge interface (it referenced value_from_long).
1639
1640 * valops.c (value_string): Find malloc with lookup_misc_func, not
1641 raw search.
1642
1643 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1644
1645 Make writing to files work properly. (Fixes to BFD are also needed.)
1646
1647 * core.c (core_open): Open file ourselves, read or r/w, depending on
1648 write_files. Use bfd_fdopenr.
1649 * gdbcore.h (write_files): New variable.
1650 * exec.c (write_files): Define variable, add set&show for it.
1651 (exec_file_command): Use write_files to open for read or r/write.
1652
1653 Make shared library reading happen automatically. These changes
1654 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
1655
1656 * inferior.h (stop_soon_quietly): Add to exported variables.
1657 * infrun.c (child_create_inferior): call solib hook, if defined.
1658 (child_attach): call solib hook, if defined.
1659 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
1660 (find_solib): Use lookup_misc_func rather than hand-rolled.
1661 (symbol_add_stub): New stub for catch_errors.
1662 (solib_add): Avoid output if !from_tty. Catch errors rather
1663 than just calling symbol_file_add and bombing.
1664 (solib_create_inferior_hook): Interface with the target process
1665 to let it read and alloc shared libs, then figure out what it did.
1666
1667 * core.c (validate_files): Fix typo, soften warning.
1668 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
1669
1670 * utils.c (fputs_demangled): Avoid duplicate printing if
1671 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
1672
1673 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
1674 (Fix from pierre@la.tce.com (Pierre Willard).)
1675
1676 * main.c (catch_errors): Change argument to a char * from an int,
1677 since a char * can point to a struct full of glop, but an int
1678 is not guaranteed to be able to hold a pointer.
1679 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
1680 breakpoint_re_set_one, breakpoint_re_set): Adapt.
1681 * core.c (core_open, solib_add_stub): Adapt.
1682 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
1683
1684 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1685
1686 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
1687 by adding .NOEXPORT target.
1688
1689 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1690
1691 * GDB-4.0 release!
1692 * Update README.
1693 * Makefile.in (VERSION): Roll to 4.0.
1694 (gdb.tar.Z): Make refcard.ps as well, for shipment.
1695
1696 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1697
1698 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
1699 more on printsyms.
1700
1701 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
1702 "gdb-all.texinfo"
1703
1704 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
1705
1706 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
1707 reflect above name change
1708
1709 * WHATS.NEW: correct pointer to refcard.
1710
1711 * doc/gdb.texinfo: update New Features, Installing
1712
1713 * doc/gdbint.texinfo: add short description of configure +template
1714
1715 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1716
1717 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
1718
1719 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
1720
1721 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
1722 tar file, add dependencies for referenced doc files.
1723
1724 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
1725
1726 * coffread.c, symfile.c, stack.c: saberized.
1727
1728 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1729
1730 * doc/refcard.tex: permuted Essential Commands sec
1731
1732 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
1733 new doc for
1734 set/show symbol-reloading
1735 default set complaints 0

1740 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
1741
1742 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
1743 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
1744 breakpoint.c, main.c: lint.
1745
1746 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1747
1748 Install new configuration scheme for GDB and friends.
1749
1750 * config.sub: Translate ordinary names to three-part names.
1751 * configure: Use three-part names internally.
1752 * configure.in: Translate three-part names to filenames.
1753
1754 * README, WHATS.NEW: Update for gdb-4.0.
1755 * Makefile.in: Roll VERSION to 3.99.
1756
1757 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
1758
1759 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
1760 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
1761 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
1762 to single structures rather than arrays; when passing
1763 their address, use &. This avoids trouble with bdead compilers.
1764 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
1765 instead. This avoids portability headaches.
1766 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
1767 asked to.
1768 * source.c (open_source_file): Avoid ANSI const bdeath by
1769 skipping declaration and then casting result value.
1770 * tm-hp300bsd.h: Clarify comment.
1771 * utils.c (strstr): Result is const char *; ANSI bdeath.
1772 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
1773 since system include file defines it differently from "defs.h",
1774 though the two are equivalent for our purposes.
1775 * tconfig/hp300bsd: Add m68k-tdep.o.
1776
1777 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1778
1779 * tconfig/sun*4: Remove warnings about system assembler.
1780
1781 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1782
1783 * mcheck.c: Avoid warning about undeclared abort fn.
1784 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
1785 it causes recursive calls to error() when used in cleanups.
1786 To do so requires that we make it a function, so we do.
1787 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
1788 * utils.c (do_cleanups): Remove the current cleanup from the
1789 chain *before* calling it, in case error() is called from it.
1790 The result won't be pretty, but won't be an infinite loop either.
1791
1792 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
1793
1794 * dbxread.c (read_struct_type): Grok anon structs for C++.
1795 (vb_name, vptr_name): Null terminate these strings.
1796
1797 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1798
1799 Minor bug fixes from BSD Net2 gdb:
1800
1801 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
1802 returns 0, there is no previous frame.
1803 * breakpoint.c (commands_command): If !from_tty, don't call
1804 input_from_terminal_p().
1805 * dbxread.c (record_misc_function): Speed up slightly.
1806 (compare_psymbols): Ditto.
1807 * infcmd.c (do_registers_info): Take a second argument to
1808 determine whether to print float registers. "info registers"
1809 does not do so anymore. "info all-registers" does, now.
1810 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
1811 arg and ignore it.
1812 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
1813 * inflow.c (initialize_inflow): Set tflags_ours correctly.
1814
1815 Other fixes:
1816
1817 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
1818 executing_breakpoint_commands if we are interrupted by error.
1819 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
1820 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
1821 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
1822 catch_errors() so we can setup the frame regardless of whether
1823 the shared libs work.
1824 * ieee-float.c (double_to_ieee_extended): Get exponent from
1825 right place in little-endian systems. From John Carey.
1826
1827 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1828
1829 * main.c: Remove unused terminating_signals and catch_termination().
1830 (long_options): Terminate with a zero element.
1831 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
1832 (gdb_readline): Make call-compatible with readline.
1833 (init_signals): Improve comments re vfork vs. signal.
1834
1835 * utils.c (prompt_for_continue): Use new gdb_readline().
1836 If we prompt for continuation, we don't let CR repeat the previous
1837 command, once we get back to a prompt. It's too easy to keep
1838 hitting CR, expecting "--more--" prompts, and have some long
1839 command start repeating on you.
1840
1841 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1842
1843 * blockframe.c (frameless_look_for_prologue): Speed up by
1844 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
1845 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
1846 Define two variants, one faster.
1847 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
1848 and return zero, rather than giving an error.
1849 (setup_arbitrary_frame): Initialize the PC in the new frame.
1850 (skip_prologue): Add a second arg saying whether we're just
1851 checking for a frameless function or not.
1852
1853 * core.c (core_open, core_close, core_xfer_memory): Move
1854 section table pointers and bfd* into the target_ops.
1855 (core_open): Allow errors in shared lib reading, etc.
1856 (core_files_info): Describe shared library sections.
1857
1858 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
1859 exec_files_info, set_section_command): Move section table
1860 pointers and bfd* into the target_ops.
1861 (add_to_section_table): Add BFD to section table.
1862
1863 * target.c (target_xfer_memory, target_info): Pass target to
1864 xfer_memory and target_info functions.
1865 * target.h: ''
1866
1867 * gdbcore.h: Move struct section_table.
1868 * target.h: New home of struct section_table.
1869
1870 * solib.c (solib_add): New argument is the target_ops whose
1871 section list is to be added to, if any. Reallocate the
1872 sections in that target to add any that come from shared libs.
1873 (throughout) so_sections renamed to sections.
1874 (solib_xfer_memory): Deleted.
1875 * tm-sunos.h (SOLIB_ADD): Add target argument.
1876 (SOLIB_XFER_MEMORY): Delete.
1877
1878 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1879 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
1880 from target_ops. It's the same on all targets. Add two section
1881 pointers to target_ops.
1882
1883 * stack.c (find_relative_frame): Dump ancient algorithm for
1884 "down", just use handy "next" pointers.
1885 (frame_command): Don't error if there is no stack; let user
1886 set one.
1887
1888 * inflow.c (new_tty_prefork, new_tty): New prefork routine
1889 modifies static state in the parent process; new_tty itself
1890 runs in the child and modifies the child's file descriptors
1891 to match the saved static state.
1892 * infrun.c (child_create_inferior): Call new_tty_prefork,
1893 fork, then new_tty.
1894
1895 * infptrace.c (child_xfer_memory): Add ignored target arg.
1896 * remote-eb.c (eb_xfer_inferior_memory): ''
1897 * remote-nindy.c (nindy_xfer_inferior_memory): ''
1898 * remote-vx.c (vx_xfer_memory): ''
1899 * remote.c (remote_xfer_memory): ''. Rename from
1900 remote_xfer_inferior_memory.
1901
1902 * main.c (main): Only try to attach "corefile" argument if
1903 it starts with a digit.
1904
1905 * symfile.c (symbol_reloading): New "set/show" variable.
1906 (symbol_file_add): Shorten message about symbol reading.
1907 (add_symbol_file_command): Merge with add_syms_addr_command,
1908 since this should work on all targets now.
1909 (stop_whining): Default to zero, to shut up complaints
1910 about bad symbol tables on many systems.
1911 (free_named_symtabs): Just exit unless symbol_reloading.
1912
1913 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
1914 and add comment explaining shared library screw.
1915
1916 * source.c: #if defined => #ifdef.
1917
1918 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1919
1920 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
1921
1922 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1923
1924 * doc/rdl-apps.texinfo: provide default readline-appendix finder
1925 (doc/Makefile knows how to make one for local config)
1926
1927 * Makefile.in: use doc/Makefile for doc targets
1928
1929 * doc/Makefile: GDB documentation now has its own Makefile
1930 doc/refcard.tex: renamed from "gdbrc.tex"
1931 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
1932 doc/gdbint.texinfo: add markup in "Cleanups" chapter
1933
1934
1935 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1936
1937 * values.c (baseclass_addr): When reading target memory, use the
1938 length of the basetype, not the upper type. We've only malloc'd
1939 enough space for the basetype, leading to errors in free().
1940
1941 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
1942 ends up as a function specially, since we know the actual type of
1943 the pointed-to address. This (somewhat) fixes display of
1944 expressions that include misc_function_vector names. Try `cond 1
1945 !strcmp("a","b")' then `i b'.
1946
1947 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
1948 The child can be proceeded from inside wait_for_inferior in
1949 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
1950 getting skipped in that case.
1951
1952 * expprint.c (print_subexp): Use filtered output, since the
1953 subroutines we call use it, otherwise the output is horribly
1954 mangled, since output of wrappable stuff comes out late.
1955
1956 * Makefile.in: Bump VERSION to 3.98.1
1957
1958 * infrun.c (child_create_process): Use execlp to find the
1959 shell to exec our target program. This requires some fiddling
1960 with `environ' since there is no execlpe().
1961
1962 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1963
1964 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
1965 Minor rearrangement of refcard permits two new make targets--
1966 gdbrc.dvi DVI output for refcard, using CM fonts
1967 gdbrc.ps PostScript refcard, using PS fonts
1968
1969 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1970
1971 * GDB-3.98 release.
1972
1973 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
1974 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
1975
1976 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1977
1978 * doc/gdb.texinfo: last changes for release.
1979 Minor typo and formatting fixes; incorporated most fixes remaining from
1980 filed mail commenting on earlier drafts.
1981
1982 Added warnings: pipes don't work in run command;
1983 conditions are converse of assertions;
1984 step over fn without debug info goes to next fn;
1985 vars may have "wrong" values near fn entrance, exit
1986
1987 Added example from Kingston on printing repeated nonadjacent values
1988
1989 Added explicit mention that in Emacs gdb mode C-c and C-z are like
1990 shell mode for signals
1991
1992 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
1993 doesn't sound so much like its parent "Stopping and Continuing"; also
1994 moved entries on continue to top of section, so they don't get lost.
1995
1996 Improved installation directions in appendix, added manual formatting
1997 instructions
1998
1999 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2000
2001 * configure.in: Remove xm.h and tm.h even if we aren't linking
2002 new ones, so "./configure sun4; ./configure none" does the right
2003 thing. Assume that alldeps.mak and depend are already built in
2004 srcdir, and avoid running "make" (particularly "make depend",
2005 which involves "gcc") from inside configure. Build Makefile
2006 directly rather than building Makefile.conf first.
2007 * configure: Regenerate with above changes.
2008 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
2009 to 3.98. Revise gdb.tar.Z procedure to produce a file
2010 called gdb-$(VERSION).tar.Z but which unpacks into a
2011 directory called "gdb". Move non-source files out of
2012 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
2013 (depend): Don't try to do "gcc expread.y".
2014 (expread.o): Update dependencies by hand.
2015
2016 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2017
2018 * doc/gdb.texinfo:
2019 Fixed a variety of small typos that prevented info from formatting
2020 cleanly; altered too-long heading for GPL Appendix, as discussed
2021 w/RMS; Changed date on cover to July 91.
2022
2023 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2024
2025 * doc/gdb.texinfo:
2026 (1) Applied some fixes due to comments from Larry Breed (easier ones
2027 through chapsec 5.2)
2028 (2) Eliminated use of @footnote---had my doubts about it anyways, and
2029 it's broken in latest texinfo
2030 (3) Introduced *some* use of [] for optional arguments, where
2031 explanation is not simpler by listing cmd w arg and cmd w/out arg
2032 separately. Still not using @deffn.
2033 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
2034 couple of headings are too long. Need patches to texinfo or revision
2035 to GPL-2.
2036
2037 * Partial update to README (which still needs work for this
2038 release!): (1) use of configure corrected for new script,
2039 (2) "make gdb.dvi" and "make gdb.info" mentioned.
2040
2041 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
2042
2043 * symtab.c (lookup_symbol): Don't complain right off about
2044 no debug symbols; use the misc function vector first.
2045 (list_symbols): Use misc function vector to find symbols
2046 that don't have debug info, and print them.
2047 (find_pc_symtab): Temporarily avoid fatal() when psymtab
2048 PC range doesn't match symtab PC range, as it does on the
2049 MIPS because our symtab reading isn't perfect.
2050
2051 * dbxread.c (dbx_symfile_read): Make warning about
2052 "no debug symbols" slightly nicer.
2053
2054 * source.c (select_source_symtab): If "main" symbol exists,
2055 but decode_line_spec can't find line info, don't just return
2056 a zero; try other source symtabs or give an error.
2057
2058 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
2059 their low addresses first, then rip through fixing high addrs.
2060
2061 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
2062 <runene@ifi.uio.no>.
2063 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
2064
2065 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2066
2067 * Minor, mostly mechanical, cleanup of doc subdir for clean
2068 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
2069 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
2070
2071 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
2072
2073 Mostly MIPS and general symbol-reading fixups.
2074
2075 * doc/gdbint.texinfo: Add documentation on symbol-reading
2076 interface.
2077
2078 * mipsread.c: Remove kludges around #include "ecoff.h".
2079 Remove redefinitions of a_magic, etc, no longer used.
2080 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
2081 Fix global overview comments to match symfile.c protocol.
2082 (mipscoff_new_init): Eliminate cur_hdr if we have one.
2083 (mipscoff_symfile_read): Eliminate unused code. Avoid
2084 sorting all the symtabs, when all we have read here is psymtabs.
2085 The symtabs are sorted as they are created anyway. Tell
2086 condense_misc_bunches whether we're mainline.
2087 (psymtab_to_symtab_1): Pass filename when recursing, to make
2088 stack trace more informative.
2089 (parse_partial_symbols): Assume cur_hdr as argument.
2090 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
2091 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
2092 the TYPE_NAME of char *, since that's done in symfile.c.
2093 (free_numargs, parse_symbol, add_symbol, add_block,
2094 shrink_linetable): Declare these fns void.
2095 (upgrade_type): Convert tree of if's to switch. Clean up
2096 bogus "off == 0" handling with a complaint. Avoid setting
2097 field bitpos and bitsize of array with lower and upper bounds.
2098 Check specified bitsize of elements against their actual type's
2099 bitsize, and complain if different. Complain about unknown
2100 type qualifiers.
2101 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
2102 (psymtab_to_symtab_1): Print names of subsidiary files that
2103 are being read in. FIXME, we read far too many files. This code
2104 is not the problem, the problem is in parse_fdr where the psymtabs
2105 are set up.
2106 (cross_ref): Result should indicate that we used one aux entry
2107 normally, or two if we encountered a "next" entry. This used
2108 to leave the caller pointing at the wrong aux entry.
2109 (add_symbol): If overflowed cur_block, reallocate it larger,
2110 chase all pointers to it, and complain(), rather than clobber memory.
2111 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
2112 (new_field): Only allocate one field initially, not two.
2113 Pull ++ out of macro argument. Simplify.
2114 (_initialize_mipsread): Avoid initialization of importd
2115 global_psymbols and static_psymbols.
2116
2117 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
2118 to properly set pst->symtab; avoid searching for it.
2119 (symfile_fns): Improve comments, add a FIXME.
2120 * dbxread.c: Update comments to reflect symfile protocol.
2121 (read_ofile_symtab, end_symtab): Return the symtab.
2122 (psymtab_to_symtab_1): Set pst->symtab.
2123
2124 * coffread.c (coff_symfile_read): tell condense_misc_bunches
2125 whether we're mainline.
2126
2127 * symfile.h (sym_fns): Remove unused sym_discard member.
2128 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
2129
2130 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
2131 the environment variable is not.
2132 * infcmd.c (finish_command): Use filtered printfs.
2133 * cplus-dem.c: Add struct tags to a few unnamed structs.
2134 * valops.c (value_coerce_array): Improve comments.
2135 * valprint.c (type_print_varspec_suffix): Print array size only
2136 if greater than zero.
2137 * m88k-tdep.c: Shift some lines left by one space, that had
2138 apparently been trashed at some point.
2139 * TODO: More things to do, a few got done.
2140
2141 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2142
2143 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
2144 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
2145 comments.
2146 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
2147 * expread.y, findvar.c, symmisc.c: Ditto.
2148 * printcmd.c (address_info): Update printed forms of LOC_
2149 symbols. Elim LOC_EXTERNAL.
2150 (print_frame_args): Keep track of param stack offsets before
2151 re-looking up to find the local register param is kept in.
2152
2153 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
2154 Further integration of mipsread into gdb. Eliminate unused
2155 routines, duplicate declarations. Handle static symbols in
2156 psymtabs as well as external symbols. When reading symtabs,
2157 insert symbols into the correct block (global, static, or a local
2158 block).
2159 (read_mips_symtab, parse_partial_symbols): Don't pass useless
2160 "incremental" arg.
2161 (mipscoff_symfile_read): Don't call select_source_symtab.
2162 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
2163 rather than SYMBOL_VALUE.
2164 (parse_external): Comment clobbering of top_stack.
2165 (parse_partial_symbols): Update comments. Allocate and parse
2166 static symbols as well as external symbols. FIXME, enum values
2167 are not handled in this pass, but should be. Inline new_psymbol.
2168 Use SYMBOL_VALUE_ADDRESS.
2169 (psymtab_to_symtab_1): Read symbols into global static block
2170 by default (until enter some function's local block context).
2171 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
2172 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
2173
2174 * source.c (select_source_symtab): Select a source symtab
2175 from either the symtabs or, failing that, the psymtabs.
2176 (list_command): Update error message.
2177 (forward_search_command, reverse_search_command): Use getc, not
2178 fgetc, for speed. FIXME, add comment about buffers that die if
2179 overrun by long line.
2180
2181 * values.c (unpack_field_as_long, modify_field): Avoid shifting
2182 by an entire word, which is not portable, if we have a 32-bit
2183 field. (Code in dbxread.c already turns such bitfields, if
2184 aligned, into ordinary ints, but fixing this will help for other
2185 symbol formats and for future changes.)
2186 * core.c (core_open): Handle ANSI const brain death.
2187 * utils.c (vprintf): Fix varargs typo.
2188
2189 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
2190
2191 * findvar.c (find_var_value): Handle &function better.
2192 * TODO: Document work needed on &fn and &array.
2193 * printcmd.c (print_address_symbolic): New arg is the prefix
2194 to print if a name is printed.
2195 (print_address_demangle): Honor "set print address" now.
2196 Use new arg above to improve spacing of output.
2197 * valprint.c (val_print): When printing function pointers,
2198 print symbolic form too.
2199 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
2200
2201 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2202
2203 * core.c (memory_error): Reword error msg to mislead less.
2204
2205 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
2206
2207 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
2208 parse_partial_symbols): Use newer BFD internals (external_filehdr
2209 and external_aouthdr), byte-swap the fields that we care about
2210 before using them, and make the file header data local to
2211 read_the_mips_symtab rather than global.
2212
2213 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
2214
2215 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
2216 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
2217
2218 * main.c (command_line_input): Flush stdout and stderr
2219 before every call to readline. This reportedly fixes a bug
2220 that comes up in Sys V running emacs-gdb and/or xxgdb,
2221 when stdin/out are pipes or sockets.
2222
2223 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2224
2225 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
2226 Avoid declaring Makefile dependencies, because GNU Make stupidly
2227 tries to update it if we do.
2228
2229 * coffread.c: Revise for minor changes to bfd internal coff
2230 indexes.
2231
2232 * configure: If -template= is given a relative path, make it
2233 absolute before recurring in subdirectories.
2234
2235 * configure, configure.in, Makefile.in: Install "configure" script
2236 as replacement for config.gdb.
2237 * config.gdb, Makefile.dist, Makefile.sdir: Remove
2238 * README: Update for configure, mostly. FIXME.
2239
2240 * Add dec3100 as equivalent to littlemips. Indicate in all host &
2241 target config files that they are for the host. When the lines
2242 get copied into the Makefile, this makes it more obvious what's
2243 up.
2244
2245 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2246
2247 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
2248 tabs, which end up in the disassembler output inadvertently.
2249
2250 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
2251
2252 Make it compile cleanly in an ANSI GCC2 environment.
2253
2254 * blockframe.c: <stdio.h>
2255 * cplus-dem.c: free takes a void *, ifdef __STDC__
2256 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
2257 LONG_MAX/radix.
2258 * defs.h (alloca): Avoid doing anything if alloca already def'd.
2259 * stddef.h, stdlib.h: Remove these files.
2260 * symtab.c: Avoid declaring qsort, close.
2261 * symfile.c: Avoid declaring close.
2262 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
2263 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
2264
2265 Assorted other changes.
2266 * dbxread.c: include "libaout.h", not "liba.out.h".
2267 * printcmd.c (print_frame_args): Set recurse properly for
2268 indentation of struct and array parameters.
2269 * valops.c (value_cast): Allow cast to void.
2270 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
2271 single_step() in a target-independent fashion.
2272 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
2273 set up to be ready to continue. This makes us target independent.
2274 * infptrace.c (child_resume): Remove call to single_step; now
2275 can single step a SPARC target of any kind.
2276
2277 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2278
2279 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
2280 docn into separate sections---basically chapters, plus two loose
2281 pieces that can be configured to go in different places. This
2282 allows GNU m4 to preprocess the manual without coredumping.
2283
2284 * Makefile.dist: tell TeX where to find texinfo.
2285
2286 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2287
2288 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
2289 the new target "rdl-apps.texinfo" which captures the Makefile
2290 variable that records where to find the Readline libraries.
2291
2292 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
2293
2294 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
2295 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
2296 * defs.h (const, volatile): Only define if not already defined.
2297 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
2298
2299 * README: Update for release 3.95.
2300 * config.gdb: Don't create readline dir in subdir builds.
2301 * main.c: Include with "..." form for non-system include files,
2302 so "gcc -MM" for "make depend" works.
2303 Include readline files with "...h" rather than <readline/...h>.
2304 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
2305
2306 * coffread.c: Undo minor damage done by Rich Pixley. Use
2307 different internal and external representations of COFF
2308 data structures. Use new BFD routines for swapping them in and
2309 out.
2310 * symfile.c (free_named_symtabs): Avoid freeing file names that
2311 are null or empty. Old i960 tools seem to produce files that
2312 claim to have empty names, causing each successive file read
2313 to blow away the previous one.
2314 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
2315 Move deferred_stores to top of file, but don't separate its
2316 #define's from its variable. Add commentary.
2317 * Makefile.dist: Fix Rich damage; undo "configure" changes in
2318 favor of keeping the (working) config.gdb. Move readline
2319 library up a notch.
2320
2321 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
2322
2323 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
2324 debug info.
2325 * infptrace.c (fetch_registers): no result, since now void.
2326 * tconfig/news: target depends on m68k-tdep too.
2327
2328 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2329
2330 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
2331 gdb.dvi target
2332
2333 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
2334 applied various small fixes due to or inspired by RMS comments
2335
2336 * doc/gdb.texinfo: finished using all RMS comments, save those for
2337 appendices on readline and cmd history (which are in other source
2338 files)
2339
2340 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2341
2342 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
2343 chapter 9; (2) documented 'break' command's menu mode for
2344 overloaded names, in response to hgs problem report C++ p-31
2345
2346 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2347
2348 * doc/gdb.texinfo: (1) better introductory example; (2) more
2349 consistent use of @code, @samp, @file, @kbd throughout; small
2350 cleanups to first three nodes; (3) new "Contributors" node;
2351 (4) Appendix, Renamed Commands; (5) divert specialized startup
2352 instructions to "Targets" chapter for generic manuals, while
2353 leaving them up front for manuals specific to specialized
2354 environments; (6) apply fixes from RMS comments through chapter 4.
2355
2356 * pretex.m4: modify explanatory text slightly (and redefine
2357 "regexp") to keep GNU m4 from complaining. (It still crashes
2358 later, but one step at a time...)
2359
2360 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
2361
2362 * readline/readline.c (update_line): Avoid dereferencing a pointer
2363 before comparing it to its bounds. Saber caught this.
2364 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
2365 and only set PC if tgetstr returned non-null. Saber caught this.
2366
2367 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2368
2369 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
2370 stuff for config manual) here where it counts; updated
2371 to use new subdir structure (gdb/doc/).
2372
2373 * Makefile: generated from above via
2374 config.gdb none
2375 before checkin
2376
2377 * gdbint.texinfo: added instructions on generating gdb.info* files
2378 locally for release. These are ordinary info
2379 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
2380 Makefile)---but due to use of texinfo 2, can't count on makeinfo
2381 to generate these, so we distribute them already formatted.
2382
2383 * gdb.texinfo: included full Info node and menu crud (as generated
2384 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
2385
2386 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
2387 put in comments-for-future gdb.info target (one day makeinfo will
2388 work again).
2389
2390 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2391
2392 * gdb.texinfo: Updated to include new or old undocumented
2393 commands, at least the following (perhaps some others I forgot to
2394 record): info f, info float, info path, info program, info s, info
2395 set, info source, info terminal, info types, info user, set/show
2396 print object.
2397 Also covered all recent GDB command renames for v4.
2398
2399 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2400
2401 * mipsread.c: Rather than keeping count of how many symtabs
2402 and psymtabs we have, for sorting purposes, count them when
2403 we need to sort. This fixes bug in rereading of symbol tables.
2404
2405 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2406
2407 * infcmd.c: renamed "info path" to "show paths"
2408 * gdbrc.tex: documented above.
2409

2417 * Makefile.dist: Roll VERSION to 3.95.
2418 Fix up "saber_gdb" to work again.
2419 * saber.suppress: Update.
2420
2421 * coffread.c, exec.c, infptrace.c, inftarg.c, remote.c, solib.c,
2422 symtab.h, target.c, target.h: Lint.
2423 * core.c: setup and select frame after reading shared libs,
2424 else reading shared libs will clobber them. Lint.
2425 * utils.c (error): Force out any buffered wrap text.
2426
2427 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2428
2429 * remote.c: Remove decls of memory_insert_breakpoint
2430 and memory_remove_breakpoint, no longer used. (Suggestion of
2431 Jan Norden).
2432
2433 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
2434 to make it easier to interface to "configure"'d libraries.
2435
2436 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
2437
2438 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
2439 aliases for set/show print.
2440
2441 Thu May 2 11:22:02 1991 Jim Kingdon (kingdon at cygint.cygnus.com)

2463
2464 * m88k-xdep.c: #if 0 out core_file_command.
2465
2466 * values.c ({unpack_,value_as_}pointer): Just call
2467 {unpack_,value_as_}long (for now anyway).
2468
2469 * m88k-tdep.c (get_saved_register): Make get_reg a dc_word_t (*)().
2470 (psr_register): Change return type to dc_word_t.
2471
2472 * m88k-tdep.c (tdesc_read_function): Comment out call to ptrace.
2473
2474 * m88k-tdep.c (get_saved_register): Add lvalp parameter.
2475

2479 m88k-xdep.c: Don't mention stack_error.
2480
2481 * {x,t}config/m88k ({X,T}DEPFILES): Add missing files.
2482
2483 * mtrace.c: Don't typedef things like size_t, just #define them.
2484
2485 * coffread.c [TDESC]: #if 0 out references to coffsyn.
2486
2487 * symtab.h (struct symtab): Include EXTRA_SYMTAB_INFO.

2494
2495 * coffread.c [TDESC]: Move setting of debug_info from
2496 coff_symfile_read to find_linenos and make it work with BFD.
2497
2498 * cplus-dem.c [__STDC__]: Make x{m,re}alloc return void*.
2499
2500 * signame.c: Cast const char* to char* when assigning to sys_siglist.
2501
2502 * utils.c (strsave): Make arg const char* not char*.
2503
2504 * infrun.c (wait_for_inferior) [SHIFT_INSN_REGS]: Use
2505 bpstat_explains_signal (stop_bpstat) not stop_breakpoint.
2506
2507 * tm-88k.h (START_INFERIOR_HOOK): Make tdesc_handle a dc_handle_t.
2508
2509 * tm-88k.h (EXTRACT_RETURN_VALUE): Use char * not void *.
2510
2511 * findvar.c (read_var_value, case LOC_CONST_BYTES): Put the address
2512 in a char *, not a CORE_ADDR. Use SYMBOL_VALUE_BYTES.
2513
2514 * tm-88k.h (INIT_EXTRA_FRAME_INFO): Use fci not prev (fci is
2515 prev except from create_new_frame). Make next_frame a
2516 local variable.
2517 Declare get_prev_context.
2518 {x,t}m-88k.h: Enclose USG and BCS defines in #if !defined.
2519 m88k-{opcode.h,pinsn.c,xdep.c,tdep.c}: New files (same contents as

2521 time).
2522
2523 Thu May 2 17:53:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2524
2525 Mips bringup and general cleanup

2528 * infptrace.c (PT_WRITE_D, PT_READ_D): Use correct values.
2529 (This still doesn't seem to make MIPS bkpts work.)
2530 * mipsread.c: Remove dup "Reading symbol data..." msg.
2531 (symbol_file_command, add_file_command): Remove, obsol.
2532 * printcmd.c (ptype_command): Say "an enum" rather than "a enum".
2533 Wrap output appropriately.
2534 * stack.c (locals_info, catch_info, args_info): Check
2535 selected_frame rather than target_has_stack or coredumping.
2536 * valprint.c (type_print_varspec_suffix): Wrap "ptype" output of
2537 enums appropriately.
2538
2539 Wed May 1 14:10:22 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
2540
2541 * signame.c: Include defs.h and param.h.
2542
2543 * cplus-dem.c: Include defs.h and param.h.
2544 Makefile.dist: Don't hack in the "param.h".
2545 param.h: Don't include defs.h.
2546

2548 can have both ints and enum type_pieces in it.
2549 ({push,pop}_type_int): New functions.
2550
2551 Tue Apr 30 13:18:58 1991 Jim Kingdon (kingdon at cygint.cygnus.com)

2554 values.c (check_stub_method): Call error if NULL return from
2555 cplus_mangle_opname.
2556
2557 * blockframe.c, breakpoint.c, core.c, command.c, findvar.c,
2558 eval.c, expprint.c, infcmd.c, infrun.c, main.c, printcmd.c,
2559 remote.c, source.c, stack.c, dbxread.c, coffread.c, symfile.h,

2563 symtab.c, cplus-dem.c, value.h, expread.y, valprint.c,
2564 copying.awk, solib.c, inflow.c, symmisc.c
2565 : Lint. Use read_memory not read_memory_integer on CORE_ADDR's.
2566 Use {value_as,unpack}_pointer (added to values.c)
2567 not {value_as,unpack}_long on CORE_ADDR's.
2568 Use longest_to_int (added to defs.h) instead of cast to int.
2569 Remove from_tty arg to mod_path.
2570 Put symfile_bfd in {coff,dbx}read.c not symfile.h.
2571 Use OP_NULL instead of 0 where dummy enum exp_opcode needed.
2572
2573 * tm-sparc.h: Remove GET_RWINDOW_REG.
2574 (FRAME_CHAIN): Call sparc_frame_chain.
2575 sparc-tdep.c (sparc_frame_chain): New function.

2580
2581 Tue Apr 30 13:13:33 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
2582
2583 * valprint.c (type_print_base): If the type being printed is a
2584 struct containing undefined types, print "<undefine type>"
2585 as the type instead of crashing.
2586 * values.c (value_headof): Get the vtable pointer taking
2587 TYPE_VPTR_BASETYPE into account.
2588 * symtab.c, symtab.h, dbxread.c: Fix various whitespace splotches.
2589

3006 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
3007 defines for the blocks of a blockvector that contain global and
3008 file-static symbols and the first of the smaller scope contours.
3009 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
3010 decode_line_1, make_symbol_completion_list): Use the above.
3011 * coffread.c (end_symtab, patch_opaque_types): Ditto.
3012 * dbxread.c (end_symtab): Ditto.
3013 * expread.y (block): Ditto.
3014 * mipsread.c (throughout): Ditto.
3015 * symmisc.c (free_named_symtabs): Ditto.
3016
3017 * symtab.c (list_symbols): Process the first symbol of the
3018 static psymbols list.
3019 (types_info): Restore this function from its untimely #if 0.
3020 It's not perfect, but it is better than nothing.
3021 (_initialize_symtab): Restore "info types".
3022
3023 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
3024
3025 * m68k-stub.c: Remote stub for 680x0's, created from
3026 rem-m68k.shar (which is removed).
3027 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
3028 Remove RCS log stuff now that we use CVS and it blows our diffs.
3029
3030 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
3031
3032 * symmisc.c (free_named_symtab): Make it work, in its current
3033 kludgy fashion. Change result to indicate if we blew away bkpts.
3034 * dbxread.c (end_symtab): Accumulate result from
3035 free_named_symtab and print warning if we blew user's state.
3036 * symfile.h: free_named_symtab now returns an int.
3037
3038 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
3039
3040 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
3041 is the first symbol read, even if not mainline.
3042 (dbx_psymtab_to_symtab): symfile might be zero, cope.
3043 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
3044 (set_section_command): New command ("section xxx yyy" -- should
3045 be renamed to "set section xxx yyy" FIXME) which sets the
3046 base address of a section of the exec file, overriding the
3047 virtual address that BFD reports.
3048
3049 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
3050
3051 * exec.c: Add add_syms_addr_command to exec_ops, so you can
3052 load symbols at any address while examining an exec file.
3053
3054 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3055
3056 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
3057 for printing the float info is host-dependent, not
3058 target-dependent. FIXME.
3059 * i386-pinsn.c: Move #includes to top, remove useless ones.
3060 * i386-tdep.c: Don't bother including <.../reg.h> since we
3061 don't use it (and it doesn't exist on host systems).
3062
3063 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
3064 Convert negative numbers properly.
3065 (ieee_test): Make numbers really random; fix format arg.
3066
3067 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
3068 * core.c (core_detach): Unpush core_ops, which might not be on
3069 top. We used to just pop the top, which broke things. Don't
3070 need dont_repeat() any more.
3071 (core_file_command): Psst! Don't repeat it.
3072 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
3073 * expprint.c (print_subexp): Avoid switch fallthru on
3074 BINOP_ASSIGN_MODIFY, so we can print += and such.
3075 * frame.h: Fix typo.
3076 * inflow.c (kill_command): After killing inferior, print our
3077 current frame in the core file, if we have one.
3078 (generic_mourn_inferior): When inferior dies, either select
3079 the current frame (in the new target, e.g. core file), or
3080 set both the current and selected frames to NULL.
3081
3082 Changes from Peter Schauer.
3083
3084 * infptrace.c: Avoid <sys/ptrace.h> on USG.
3085
3086 * Make all file names fit in 14 characters (sigh and damn!):
3087 mv hp300hpux-xdep.c hp300ux-xdep.c
3088 mv symmetry-xdep.c symm-xdep.c
3089 mv symmetry-tdep.c symm-tdep.c
3090 mv convex-opcode.h convx-opcode.h
3091 mv tm-vxworks960.h tm-vx960.h
3092 mv tm-vxworks68.h tm-vx68.h
3093 mv Makefile.srcdir Makefile.sdir
3094 mv gdb-int.texinfo gdbint.texinfo
3095 mv remote-sa.m68k.shar rem-m68k.shar
3096 mv remote-multi.shar rem-multi.shar
3097 * Makefile.dist, README, config.gdb, convex-pinsn.c,
3098 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
3099 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
3100 names.
3101
3102 * command.c (user_info_1, user_info): New command for listing
3103 the user-defined commands.
3104
3105 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
3106
3107 * dbxread.c (really_free_pendings): Clear file_symbols
3108 and global_symbols after freeing them; otherwise, running
3109 this function twice (if it appears twice on the cleanup
3110 chain), we try to free things twice.
3111
3112 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
3113 based on text_addr (the address of text in core), not on addr (the
3114 offset between text in the .o file and in core). This change
3115 is from Peter Schauer.
3116
3117 * main.c: Define ALL_CLEANUPS as a cast of zero.
3118 (return_to_top_level): Use it.
3119 (main): Do all cleanups after each command run as part
3120 of the gdb startup sequence. Also do all cleanups before
3121 entering the command loop, and every time we exit the command
3122 loop and reenter. Before, the cleanups from the startup sequence
3123 were being left undone until the first error!
3124 (command_loop): Rename do_nothing cleanup to command_loop_marker
3125 so we can see it easily when examining the cleanup chain.
3126 (init_signals): Add another do_nothing for signal handling.
3127 (quit_command): Only try to kill target if it has execution.
3128 Problems in the target stack got us into a state where
3129 inferior_pid was nonzero but none of the targets had execution.
3130 In this state you couldn't exit gdb.
3131
3132 * dbxread.c: Two changes from Peter Schauer.
3133 (echo_command): Fflush output after an echo command.
3134 (show_history): Pass all args to cmd_show_list.
3135
3136 * utils.c (init_malloc): Call mtrace to turn on tracing
3137 if the environment variable MALLOC_TRACE is set to a file name.
3138 * mtrace.c: Add source file which provides a log of every malloc,
3139 free, and realloc to a trace file.
3140 * mtrace.awk: Add source file which analyzes the trace file.
3141 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
3142 (VERSION): Roll to 3.94.3.
3143
3144 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
3145 (check_duplicates): Don't bother with watchpoints.
3146 (set_raw_breakpoint): Comment about danger of this routine.
3147 (watch_command): Parse and eval all args before calling
3148 set_raw_breakpoint.
3149
3150 * solib.c (find_solib): Avoid error in referencing memory to
3151 see if any more shared libraries have been added. This is
3152 particularly useful if the target has terminated. Bug reported
3153 by Peter Schauer.
3154
3155 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
3156 in bringing up 3.94.2 on the Sun-3.
3157
3158 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
3159 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
3160 expression (in scope) before reenabling watchpoint.
3161 * signame.c (init_sigs): Add missing declaration of i, fix
3162 sys_siglist declaration.
3163 * source.c (list_command): Fixed range computation to use
3164 lines_to_list ().
3165 * stack.c (backtrace_command): Do not allow command if target has
3166 no stack, print informative error message.
3167 * target.c (target_command): Do not write into command line
3168 because this fails if the target command is used in a user defined
3169 command. [This change was enhanced by gnu to support any-
3170 unique-prefix matching on target names.]
3171 * valops.c (value_struct_elt): Avoid infinite loop on an
3172 erroneous attempt to print the member of function (try p main.p).
3173
3174 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3175
3176 * expread.y (name_no_typename): Avoid reduce/reduce errors
3177 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
3178 Since the GDB parser really doesn't use name_no_typename in a
3179 name-only context, the parser can't tell the diff between
3180 names and numbers here. Avoid allowing a name_no_typename
3181 to be a NAME_OR_*INT to resolve the conflict.
3182
3183 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3184
3185 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
3186
3187 * valprint.c (val_print_fields): bitfield printing didn't handle
3188 byte order. Indirect through a few more fns to cope.
3189
3190 * values.c (modify_field): also cope with byte order.
3191
3192 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
3193
3194 Cleanup for release 3.94.2:
3195
3196 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
3197 include files. Roll version to 3.94.2.
3198
3199 * coffread.c (init_stringtab): Read length into unsigned char
3200 array before swapping; don't assume 32-bit longs.
3201
3202 * target.c (target_info): Don't bother with get_sym_file, just use
3203 the symfile global variable.
3204 * symtab.h, symfile.c (get_sym_file): Delete it.
3205
3206 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
3207 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
3208 (read_type): Replace one more error() with complain().
3209
3210 * mipsread.c (parse_partial_symbols): Replace printf with complain.
3211
3212 * i960-tdep.c: Fix copyright attribution.
3213
3214 * config.gdb: Quote all backquotes in doublequotes. You can
3215 quote me on that. BSD 4.4 shell found this one.
3216
3217 * infptrace.c (throughout): The third argument to ptrace is an
3218 int *, not an int.
3219
3220 * infrun.c (wait_for_inferior): When program has terminated, we
3221 have to call target_terminal_ours before we pop that target off
3222 the stack (e.g. before a call to target_kill or
3223 target_mourn_inferior). This fixes problem where a program
3224 terminates, then GDB stops for (tty output) and you have to type
3225 "fg" to the shell to resume it. FIXME: This code for what to
3226 do after termination really should be in normal_stop instead.
3227
3228 * gdbcore.h (read_memory_check): Change declaration; it changed
3229 names months ago.
3230
3231 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
3232 4.4 prereleases, this avoids a bug in their sgtty compatability
3233 support.
3234 * remote.c: Use terminal.h rather than hand-rolling the same.
3235
3236 * signame.c, signame.h (psignal): Arg is unsigned, not int.
3237 * utils.c (strsave, strstr): Fix arg types.
3238 * valprint.c (val_print): lint
3239
3240 MIPS symbol table support from Per Bothner:
3241
3242 * symfile.c (symtab_fns): Remove initializer table that needs to
3243 be hacked for each new symbol file format supported.
3244 (add_symtab_fns): New function, chains symbol table
3245 handlers into the global list.
3246 (symfile_init): Search this list.
3247 * symfile.h: Add next pointer, declare add_symtab_fns.
3248 * coffread.c (_initialize_coffread): Call add_symtab_fns.
3249 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
3250
3251 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
3252 symbol *). Thus, we no longer need the hack to trash
3253 pst->filename. Good, since that hack confused code in symfile.c!
3254
3255 (reorder_symtabs, destroy_all_symtabs): Removed static
3256 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
3257 Instead, the latter now uses a temporary array (stack-allocated
3258 from an obstack, and then freed).
3259
3260 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
3261 haven't been set in the outermost stBlock of a procedure. This was
3262 a problem with f77 binaries on Ultrix 4.?.
3263
3264 (new_symtab, new_symbol, new_type): Continue changing code to use
3265 obstacks more and otherwise conform to dbxread internal style.
3266 Made the free_code of symtabs be free_linetable (as in dbxread)
3267 instead of free_contents. This implies memory leaks when reading
3268 a new symbol table, until the conversion is finished. Did change
3269 (struct symbol) and (struct type) to be allocated on the
3270 symbol_obstack. Blocks and blockvectors are among the things
3271 still "leaking."
3272
3273 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
3274 tested much, but it solved one problem (reported by Meissner), and
3275 cleans up some other things. The problem happened when an
3276 included file contains actual code (functions) and not just
3277 definitions. The mips coff is a little inconvenient there, since
3278 it may cause a procedure to be mapped to the wrong psymtab.
3279
3280 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
3281 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
3282 this will need work for the new core paradigm.
3283
3284 Opcode patches from the net:
3285
3286 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
3287 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
3288 missing altogether - they are added here. From Bruce Bauman.
3289 * mips-opcode.h: The low mask for C0 instructions was too small.
3290 From Garrett Lau. I modified the fix to check the entire 32-bit
3291 opcode.
3292
3293 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
3294 Bauman.
3295
3296 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3297
3298 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
3299
3300 * dbxread.c (read_type): Pointer subtraction (value_sub in
3301 valarith.c) sometimes failed because the types of the
3302 pointers being subtracted were not identical.
3303 These differed because dbxread.c was allocating pointer types
3304 using dbx_alloc_type+smash_to_pointer_type instead of
3305 lookup_pointer_type. I failed to find a justification for the
3306 former, so I changed it to use the latter. Similarly, I
3307 replaced smash_to_function_type by lookup_function_type,
3308 and smash_to_reference_type by lookup_reference_type.
3309
3310 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
3311 _initialize_mipsread): corresponding changes.
3312
3313 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
3314
3315 * source.c (mod_path): Do tilde_expand on each component of the path,
3316 rather than on the (list of) paths as a whole.
3317 (print_source_lines): Set first_line_listed in addition to
3318 current_source_symtab and current_source_line. If the source was
3319 not findable, after a "dir" command to fix the problem,
3320 a "list" would get the wrong lines.
3321
3322 While I was there... (gnu):
3323
3324 * dbxread.c (read_type): Change error to complaint.
3325
3326 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3327
3328 First attempt at detailed understanding of symbol table memory alloc.
3329
3330 * dbxread.c (dbx_symfile_read): Free our string table if we
3331 aren't the mainline. Free the "info" struct since we're done with
3332 it.
3333 (init_psymbol_list): Free any previously allocated psymbol lists.
3334 (): FIXME: Should realloc-down the psymbol lists when done reading
3335 the main symbol file?
3336
3337 * symmisc.c (free_symtab): Free fullname field too.
3338
3339 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
3340 (REGISTER_ADDR): Make result type unsigned int.
3341
3342 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
3343 define REGEX must also define REGEX1 (its dependency).
3344
3345 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
3346
3347 * tconfig/i960: No longer works, points you at vxworks960 or
3348 nindy960.
3349
3350 * xgdb.c, XGDB-README: Remove file. Users can get the much
3351 better xxgdb.
3352 * Makefile.dist: Remove all trace of xgdb.
3353
3354 * breakpoint.c (breakpoint_1): Pass demangle arg to
3355 print_address_symbolic.
3356 (clear_breakpoints): Remove unused function.
3357 (breakpoint_re_set_one): Guts of breakpoint_re_set.
3358 (breakpoint_re_set): Use catch_errors to do them all anyway.
3359
3360 * gdb-int.texinfo (Host versus Target): Add section on what is
3361 a "host" feature versus what is a "target" feature.
3362
3363 * infcmd.c (path_command, path_info): Handle the PATH variable
3364 (object search path) as conveniently as the source search path.
3365 * environ.c (set_in_environ): Set some vars in GDB's environment,
3366 in addition to the child's. PATH, G960BASE, G960BIN for starters.
3367 * source.c (mod_path): New function, from guts of
3368 directory_command, modifies a path. Used by path_command.
3369 (directory_command): Call it.
3370 * defs.h (strsave): Declare.
3371
3372 * utils.c (sevenbit_strings): Add new printing option.
3373 (printchar): Use it.
3374 (strsave): Provide this handy helper routine.
3375 (set_width_command): Rename set_screen_width_command.
3376 (_initialize_utils): "set screen-width" => "set width";
3377 "set screen-height" => "set height"; add sevenbit-strings.
3378
3379 * infcmd.c (do_registers_info): Print floating point registers
3380 in raw hex as well as float format, regardless of whether it is
3381 a "virtual" convertible register.
3382 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
3383 regs as a double, just in case it's being used that way.
3384 * values.c (unpack_long): Comment on array/function coercion.
3385 (unpack_double): Argument is in target byte order now. For
3386 integer arguments, just call unpack_long and float the result.
3387 * m68k-tdep.c: include defs.h for "const" handling.
3388 * remote-nindy.c: Use ieee-float stuff.
3389 (nindy_fetch_registers): Unpack double regs to host double, then
3390 to extended.
3391 (nindy_store_registers): Pack extendeds to host double, flip
3392 around by misusing unpack_double, send as target double.
3393
3394 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
3395 zero, as when stopped at the first instruction of a process.
3396
3397 * blockframe.c: Fix filename in comment (param.h => tm.h).
3398 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
3399 * tm-68k.h: Fix typos.
3400
3401 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
3402
3403 Changes from a bringup on the DEC Vax under Ultrix 4.0.
3404
3405 * coredep.c (fetch_core_registers): Pass end-address of register
3406 section to register_addr as expected. Don't call supply_register
3407 if we'd just pass it garbage.
3408
3409 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
3410
3411 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
3412
3413 * target.c (push_target, target_info): Cast enums to int for < or
3414 > comparison.
3415
3416 * stack.c (print_frame_info): Identify source file & line
3417 even if we can't print it.
3418
3419 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
3420
3421 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
3422
3423 Clean up IEEE floating point support.
3424
3425 * ieee-float.h: New file.
3426 * ieee-float.c: Write real routines to convert between host
3427 doubles and various target IEEE extendeds.
3428 * m68k-xdep.c: Eliminate assembler code for extended floats.
3429 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
3430 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
3431 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
3432 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
3433 double_to_ieee_extended.
3434 * i960-tdep.c: Define ext_format_i960.
3435 * m68k-tdep.c: Define ext_format_68881.
3436 * sparc-tdep.c: Define ext_format_sparc, though unused.
3437 * Makefile.dist (HFILES): Add ieee-float.h.
3438 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
3439 macros.
3440
3441 Obsolete the "coffstrip" program in favor of using BFD's strip.
3442
3443 * nindy-share/coffstrip.c: Remove file.
3444 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
3445 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
3446 * tconfig/nindy960: Remove reference to coffstrip.o.
3447
3448 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
3449
3450 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3451
3452 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
3453 * dbxread.c: Remove static symfile_bfd.
3454 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
3455 it is not used yet.
3456 * inftarg.c (child_detach): Pop the child_ops vector if the
3457 detach is successful.
3458 * remote-nindy.c (nindy_create_inferior): Don't push a new
3459 nindy_ops since nindy uses the same one for execution and memory
3460 examination anyway.
3461 * core.c (core_ops): Use child_attach and child_create_inferior
3462 rather than default attach and create_inferior functions.
3463
3464 Handle floating point registers in core files.
3465
3466 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
3467 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
3468 This version untested since BFD doesn't yet support sun3 core
3469 files.
3470 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
3471 conventions. Fix comments and style. This version has not
3472 been compiled yet, since we have no HP inhouse.
3473 * core.c (get_core_registers): Look for two sections, ".reg"
3474 and ".reg2", and pass both to fetch_core_registers sequentially.
3475
3476 Revise directory path yet again.
3477
3478 * source.c (forget_cached_source_info): Not static any more.
3479 (init_source_path): New default source path is "$cdir:$cwd".
3480 (dir_command): Handle variable arguments ($cdir, $cwd).
3481 (source_info): Print "Compilation directory" rather than
3482 "Originally compiled in" to remind people of $cdir.
3483 (openp): If the path contains $cwd, use current directory.
3484 (open_source_file): If compilation directory is known, replace
3485 first $cdir in path with the compilation directory.
3486 (print_source_lines): Even if we can't print the lines, set the
3487 current symtab and line for future commands like "info source" or
3488 "breakpoint". Also, error message now contains the file name,
3489 line number, and file access error message.
3490 (_initialize_source): Fix help text to describe changes.
3491 * main.c (cd_command): Forget cached source info when we chdir.
3492 * utils.c (strstr): Add simple implementation.
3493
3494 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
3495
3496 * coffread.c (read_one_sym, init_linetable, init_stringtab):
3497 Byte-swap COFF symbol tables if necessary when reading them in.
3498 Use complain() to replace error message in one spot. Needs
3499 corresponding change in bfd/coff-code.h to make some symbol
3500 swapping routines non-static.
3501
3502 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3503
3504 Merge changes from Eirik Fuller, for UTek.
3505
3506 * defs.h (errno): Add declaration.
3507 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
3508 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
3509 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
3510 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
3511 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
3512 declarations of errno.
3513
3514 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
3515
3516 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
3517 <rpc/rpc.h> and <rpc/types.h>.
3518
3519 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
3520
3521 * i960-tdep.c (examine_prologue): Add new argument limit,
3522 which stops the scan at the end of the prologue, or at the PC.
3523 This fixes a problem where it walks down into the code for the
3524 user's statements if that code looks like function prologues.
3525 Mark Fox and I have been bouncing this code back and forth, making
3526 small changes to it. Callers changed to match.
3527
3528 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
3529
3530 Cleanup for gdb-3.94 release final:
3531
3532 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
3533 the .c files from vx-share and nindy-share, from the various
3534 macros, since they are not found via ALLDEPFILES.
3535 (SFILES): Add tm-i960.h.
3536 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
3537 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
3538 in the SUBDIR list.
3539 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
3540 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
3541
3542 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
3543
3544 * am29k-tdep.c: Add contribution line.
3545 (examine_prologue): Cache information about function prologues in
3546 the misc-function-vector to avoid lots of references over the
3547 serial line while examining instructions.
3548
3549 * core.c (core_close): New function made from cleanup_core.
3550
3551 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
3552 remote-vx.c, remote.c, target.c, target.h,
3553 Update target_ops vector to add attach, close, and load entries.
3554 Use add_syms_addr_command, not add_file_addr_command, for
3555 add_file. Break out close routine from existing code.
3556
3557 * dbxread.c (really_free_pendings): Don't free pending_blocks;
3558 they are in an obstack.
3559 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
3560 Lint.
3561 (define_symbol): Add symbol type parameter; change callers;
3562 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
3563 it to influence the symbol class on the i960.
3564 (define_symbol): Swap LOC_CONST's into target byte order.
3565
3566 * exec.c (exec_close): New function.
3567 (exec_file_command): Call it.
3568
3569 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
3570 Fix byte order of frame pointer.
3571 (read_var_value): Result of 0 if var's value can't be found,
3572 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
3573 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
3574 (locate_var_value): Use read_var_value and use its lazy address
3575 as the location of the var's value. Lint.
3576
3577 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
3578 instructions.
3579
3580 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
3581 obsolete Intel versions in favor of vxgdb versions.
3582 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
3583 code dealing with byte order of values, which Intel did in host byte
3584 order rather than gdb-4's target byte order.
3585 (i960_frame_chain_valid): Move to nindy-tdep.c.
3586 (examine_prologue, skip_prologue, frame_find_saved_regs,
3587 frame_args_address, leafproc_return, saved_pc_after_call,
3588 pop_frame): Add vxgdb versions from Mark Fox.
3589 (examine_prologue, frame_struct_result_address): Add code
3590 to deal with the saved value of G13 (struct return address
3591 pointer).
3592 (frame_args_address): Modify Mark's version to prefer the
3593 saved value over the current value in the topmost frame.
3594 Cache result in the frame info to avoid performance hair in
3595 callers.
3596 (print_fault): Add gdb960 code for printing faults.
3597 (_initialize_i960): Actually call check_host.
3598
3599 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
3600 add stub routines. FIXME, these currently just return zero!
3601
3602 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
3603 (attach_command): Call target_attach, not target_open, now.
3604
3605 * infrun.c (normal_stop): Make global, not static, for vx_attach.
3606 (child_attach): Rename from child_open.
3607 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
3608 don't confuse it with a zero step_resume_break_address.
3609
3610 * inftarg.c (child_detach): Eliminate inferior_pid test.
3611 (child_files_info): Clean up message a bit.
3612 (child_ops): Use child_attach, not child_open, to attach.
3613
3614 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
3615 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
3616 findvar.c to here, since it depends on the contents of the
3617 shadow_contents of breakpoints, but keep if #if 0 since it is
3618 never called.
3619
3620 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
3621 from i960-tdep.c.
3622
3623 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
3624 (ptype_command, display_command): Eliminate have_inferior_p and
3625 have_core_file_p in favor of target_has_stack or
3626 target_has_execution.
3627 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
3628 code for actually finding the values of arguments, though we still
3629 keep track of the maximum stack offset for use in printing unnamed
3630 arguments. Handle missing FRAME_ARGS_ADDRESS.
3631
3632 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
3633 (struct nindy_regs): Define registers passed to/from nindy.
3634 (nindy_fetch_registers, nindy_store-registers): Translate between
3635 nindy and GDB formats for the registers.
3636 (dcache_init): Statically allocate the cache, since it was being
3637 allocated by a malloc that was never freed anyway.
3638 (nindy_create_inferior): Error, not core dump, if no exec file.
3639 (nindy_before_main_loop): Use target_load, not target_add_file.
3640
3641 * remote-vx.c (net_load): Specify large timeout for load
3642 requests. Allow user to break out with INTERRUPT.
3643 (net_break): Remove useless code, clean up. Change callers.
3644 (parse-args, skip_white_space, find_white_space): Clean up arg
3645 parsing to cope with quoted strings.
3646 (net_wait, net_quit): Never call error, just return status.
3647 (vx_read_register, vx_write_register): Cleanup status checking.
3648 #ifdef the code based on which CPU we are using (960 or 68k),
3649 FIXME, this should be completely general but it isn't yet.
3650 (vx_xfer_memory, vx_resume): Cleanup status checking.
3651 (vx_run_files_info): Improve message.
3652 (vx_load_command): Renamed from vx_add_file_command. Allow load
3653 to be interrupted.
3654 (net_ptrace): Remove unused routine.
3655 (vx_wait): Adopt code from vxgdb960 to cope with broken
3656 connections to target machine and prompt to disconnect. Remove
3657 debug printouts. Map some EVENT_'s to SIGnals.
3658 (add_symbol_stub, vx_open): Print names of object files we found,
3659 and "ok" if we read their symbols OK. Clarify output in general.
3660 (vx_attach, vx_detach, vx_kill): Add these commands.
3661 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
3662 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
3663 "info files" output, and create_inferior, since we already have
3664 an inferior.
3665
3666 * stack.c (frame_info): Replace Frame_unknown with 0.
3667 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
3668 (return_command): Pop until the PC matches as well as the FP,
3669 so it works even if the FP is shared with another function,
3670 as in "frameless" or "leaf" procedures.
3671
3672 * symfile.c (load_command): renamed from add_file_target_command.
3673 (add_syms_addr_command): renamed from add_file_addr_command.
3674 (add_syms_command): Stub to call target_add_syms.
3675 (_initialize_symfile): Change command names and descriptions,
3676 add-file => add-syms, and load from alias to its own command.
3677
3678 * target.c (kill_or_be_killed, maybe_kill_then_attach,
3679 maybe_kill_then_create_inferior): Default for attempts to start
3680 a process, if one is already running, is to ask about killing
3681 it and retry if yes.
3682 (upstack_create_inferior): #if-0 it, strata obsolete it.
3683 (push_target, unpush_target, pop_target): to_close() a target
3684 before unstacking it.
3685 (target_info): Renamed from target_files_info.
3686 (_initialize_targets): Rename "i files" as "i target", accessible
3687 under both names.
3688
3689 * target.h: Improve comments about the target_ vectored routines.
3690
3691 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
3692 Convert commenting style to standard GNU style.
3693 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
3694 (SKIP_PROLOGUE): No longer a no-op.
3695 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
3696 (*_REGNUM): Sort register numbers.
3697 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
3698 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
3699 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
3700 are now 10 byte extendeds, not 8 byte doubles.
3701 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
3702 for nindy versus vxworks targets. FIXME, this should possibly go
3703 in the target vector.
3704 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
3705 frame_saved_regs and arg pointer with each frame.
3706 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
3707 (FRAME_ARGS_ADDRESS): Use cached result.
3708 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
3709 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
3710 (PRINT_RAMDON_SIGNAL): Call print_fault.
3711 (POP_FRAME): Now works.
3712
3713 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
3714 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
3715 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
3716 (ADDITIONAL_OPTION_HANDLER): use target_load, not
3717 target_add_file.
3718
3719 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
3720 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
3721
3722 * valarith.c (value_subscripted_rvalue): Avoid handling
3723 floats and doubles specially; it gave alignment errors. Lint.
3724
3725 * valops.c (value_of_variable, value_of_this): Error if unknown
3726 value.
3727
3728 * valprint.c (print_floating): Bcopy rather than pointer-deref,
3729 to avoid alignment problems.
3730 (value_print): Handle unknown value address.
3731 (cplus_val_print): Two args are ignored; remove them. Change caller.
3732 (val_print): Use unpack_long rather than pointer-deref.
3733
3734 * values.c: Lint.
3735 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
3736 to avoid alignment problems.
3737 (value_being_returned): Error if return value unknown.
3738 (set_return_value): Add bogosity warning, FIXME. *
3739
3740 * TODO: A woman's work is never done.
3741
3742 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
3743 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
3744 Add ieee-float.o to OBS.
3745 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
3746 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
3747 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
3748
3749 Changes to generalize the VxWorks RPC protocol slightly, to handle
3750 i960 as well as 68000.
3751
3752 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
3753 * vx-share/reg.h: Produce i960 regs #ifdef I80960
3754 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
3755 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
3756 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
3757 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
3758 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
3759 so they will move in target byte order rather than network
3760 byte order (happens to be the same).
3761
3762 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
3763
3764 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
3765
3766 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
3767
3768 * am29k-pinsn.c,
3769 Add contribution lines to various files, showing where they
3770 came from.
3771
3772 * breakpoint.c (break_insn, check_break_insn_size,
3773 read_memory_nobpt): Remove to mem-break.c.
3774
3775 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
3776 HOST_BYTE_ORDER.
3777
3778 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
3779 entry has bad register number. This change is not
3780 tested in this release, FIXME.
3781
3782 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
3783 tm-vax.h: Ditto.
3784
3785 * value.h: Force value's contents field to be aligned to hold
3786 at least a double or a long long (if supported). This avoids
3787 doing bcopy's in and out of the contents field.
3788
3789 (step_1): Avoid coredump under obscure circumstances when we
3790 have no frame.
3791
3792 * symtab.h (misc_info): Add field to misc function vector for
3793 any kind of cached information the target code desires. AMD
3794 29000 uses this to avoid repeating examine_function_prologue's.
3795
3796 * coffread.c: Lint. Remove static symfile, read_section_header.
3797 core.c (have_core_file_p): Lint: remove.
3798 expprint.c (print_subexp): Lint.
3799 infptrace.c, valops.c, valprint.c: lint.
3800
3801 Roll in changes from vxgdb-5.0.1:
3802
3803 * symtab.h: Comment byte order of each address class. Add
3804 LOC_LOCAL_ARG for frame-relative args (960).
3805 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
3806 symtab.c, symmisc.c: ditto.
3807
3808 * infrun.c (init_wait_for_inferior): Clear stop_signal.
3809
3810 * remote.c (remote_resume): Error if resume with a signal.
3811
3812 * symfile.c (prim_record_misc_function): Clear misc_info.
3813 (fill_in_vptr_fieldno): Check stub type of arg.
3814
3815 * valops.c (value_cast): Avoid looking up names of types whose
3816 name we don't know, to prevent coredump. Sun CC produces typedef
3817 rtx and the name of *rtx is zero...
3818
3819 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3820
3821 Roll in changes from final AMD 29000 port (Tiemann).
3822
3823 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
3824 for ../include/a.out.encap.h. This might not work now that BFD
3825 is separately compiled. Instead, BFD support for encap will have
3826 to translate machine type 29k into the right COFF_MAGIC.
3827
3828 * infcmd.c: Remove references to inferior_pid that aren't used
3829 in actual ptrace calls; use target_has_execution, etc.
3830 (have_inferior_p): Remove function.
3831 (program_info): Print target info rather than "process number";
3832 avoid gratuitous messages unless from_tty.
3833 (run_stack_dummy, finish_command): Set proceed_to_finish.
3834 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
3835 main.c: Lint. Lose have_inferior_p().
3836 inferior.h (have_inferior_p): Remove, lint.
3837 (proceed_to_finish): Add flag to ask that all regs be saved
3838 by normal_stop, for the few commands that need it, speeding up
3839 serial I/O. Add comments to stop_registers.
3840
3841 * remote-eb.c: Remove newline from breakpoint message we grep
3842 for. Never time out when running the user program.
3843
3844
3845
3846 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3847
3848 Roll in changes from vxgdb-5.0.1:
3849
3850 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
3851 symbol in its raw form, we are processing an unlinked ".o" file.
3852 See if the target environment has assigned it an address, using
3853 target_lookup_symbol (VxWorks does), and enter it into the symtab
3854 that way.
3855
3856 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
3857 68k versions for a simpler version that assumes zero FP at bottom.
3858 Fixes bug of truncated stack reports.
3859
3860 * target.h (target_lookup_symbol): Define this routine's args
3861 and result, finally.
3862
3863 * target.c (nosymbol): Default routine for target_lookup_symbol.
3864 (target_default): Default lookup_symbol and call_function too.
3865 (files_info): Only print has_all_memory warning if a non-dummy
3866 target follows.
3867
3868 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
3869 vx_convert_from_virtual): If target does not have floating point,
3870 zero register "values", and avoid doing cross-net conversions.
3871 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
3872 (vx_open): Rearrange code that attaches to target and reads
3873 symbols for all loaded modules, to work if some of the modules
3874 are not accessible. Add symbol_stub() and add_symbol_stub()
3875 as callbacks from catch_errors(). Allow connect attempt to be
3876 interrupted painlessly with ^C (FIXME, there are still some bugs
3877 if the interrupt happens during symbol reading.). Print
3878 final message with puts_filtered, since symbol messages are
3879 now filtered too.
3880
3881 Misc cleanup:
3882
3883 * main.c (catch_errors): Only print errstring if non-null.
3884 (command_loop): Avoid an ioctl per command to test ISATTY.
3885
3886 * remote-vx.c (net_load): make static; avoid sophomoric msg.
3887 (vx_xfer_memory): Return correct result!
3888 (vx_files_info): Indicate whether target has float or not.
3889 (vx_lookup_symbol): Complain, not error, if target gone.
3890 (vx_open): Print "Connected" msg before disabling immediate-quit.
3891 [FIXME: lookup_symbol and vx_open changes need testing.]
3892
3893 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
3894 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
3895 contributor lines and update copyrights to 1991.
3896
3897 Changes from an attempted H-PUX host port:
3898
3899 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
3900 defines PT_ATTACH and PT_DETACH but not PT_KILL.
3901 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
3902 * remote-vx.c: include <sys/time.h> for HPUX.
3903 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
3904 "core_file_command" routine to BFD regime. May not work yet.
3905
3906 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
3907
3908 * xgdb.c: Replace X10 version with some VJ version.
3909 (FIXME: Its copyright assignment is not on record.)
3910 * xgdb.c: Update include files to X11R4 (Xaw crud).
3911 (xgdb_display_source, create_text_widget): fix call to
3912 get_filename_and_charpos. Rewack source window stuff for X11R4
3913 (gleaned from include files, and "nm's" of binary libraries, since
3914 I had no doc available).
3915 (append_selection, append_selection_word): Disable with FIXME
3916 since R4 changed interface here.
3917 (create_buttons): Add back the old set of buttons.
3918 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
3919
3920 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
3921 Roll VERSION to 3.94 (not yet final though).
3922
3923 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3924
3925 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
3926 obstack_int_grow, obstack_int_grow_fast): Eliminate
3927 cast on left of assignment, which gives MIPS cc fits and is
3928 not Standard C.
3929
3930 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
3931 F_ALIAS. Use printf, not fprintf, when not passing a file
3932 pointer...
3933 (compare_opcodes): Check that identical instructions have
3934 identical opcodes, complain otherwise.
3935
3936 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
3937 was reported by Roland McGrath.
3938 (unimp): Only match if exactly zero instruction. (Roland)
3939 (branches and traps): Generate all variations of these
3940 instructions with macros, based on a single call that defines
3941 each condition name and its binary representation.
3942 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
3943
3944 * valprint.c (val_print_fields): Take, and use, format parameter.
3945 This means that "p/x struct" again prints the elements in the
3946 desired format. Changed callers.
3947
3948 * stack.c (frame_info): Use filtered output, and indicate wrap
3949 points. Remove kludgy formatting designed to avoid line wrap.
3950
3951 * utils.c (wrap_here): If the line is already full (because
3952 we had printed a long indent or long wrapped string), do an
3953 immediate newline-and-indent.
3954
3955 * m68k-pinsn.c (print_insn_arg): Bugfix from
3956 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
3957 instruction is incorrectly disassembled as bkpt #8.
3958
3959 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
3960 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
3961 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
3962 and then will dump core (sometimes). I traced it back to an
3963 uninitialized symfile_name in psymtab_to_symtab.
3964 (const_vol_complaint): Add quotes to message.
3965 (define_symbol): Only believe line number if gcc_compiled.
3966 Avoid allocating symbol if we will not return it.
3967
3968 Add target strata support so that newly established targets go
3969 into their right place in the target stack (e.g. a new exec file
3970 doesn't wipe out the ability to access the running process).
3971
3972 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
3973 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
3974 and initialize it properly in all the targets.
3975
3976 * target.h: Document strata. Change return type of push_target.
3977
3978 * target.c (nomemory): new function for dummy memory access.
3979 (tcomplain): Rename complain, now also used in symfile.c.
3980 (push_target): Push targets within strata. New return value shows
3981 whether new target is on top of stack or not. Always keep dummy
3982 target on stack.
3983 (target_files_info): Ignore dummy target.
3984
3985 * core.c (core_open): Warn user, and skip accessing file, if the
3986 core target is not the topmost target in the stack.
3987 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
3988 already handled.
3989
3990 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
3991 target_ops, it doesn't belong there since we have no regs there.
3992 Change name of target from machine => memory to clarify.
3993
3994 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
3995
3996 * Freeze version 3.93 for release.
3997
3998 * Makefile.dist: Handle vx-share and nindy-share subdirs
3999 properly when building gdb.tar.Z.
4000
4001 * symtab.c: lint; add no_symtab_msg to consolidate the messages
4002 printed in various places, so I could change just one copy.
4003
4004 * dbxread.c, coffread.c: Change references to bfd->iostream
4005 to cast to FILE *, now that BFD avoids needing types defined
4006 in other header files.
4007
4008 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
4009
4010 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
4011 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
4012 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
4013 (actually gcc -Wall).
4014
4015 * dbxread.c: Remove first_global_sym, last_global_sym, since
4016 they are never referenced.
4017
4018 * defs.h (baud_rate): Declare.
4019 main.c: Define it, and add the -b option to set it.
4020
4021 * gdb-int.texinfo: Add text on how to define a new host or target
4022 architecture, prompted by Per Bothner's questions about MIPS
4023 support.
4024
4025 * gdb.texinfo: Document "complaints". Change doc of -q since
4026 gdb no longer prints the copyright and blurb if you specify a file
4027 name to be debugged (just like Emacs). Add doc for Nindy-specific
4028 command line flags for specifying target serial port and such.
4029 Update copyright to 1991.
4030
4031 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
4032 has taken over for us the job of ripping up executable files. The
4033 crud caused Per Bothner's port to not compile.
4034
4035 * infrun.c (normal_stop): Avoid printing "Program exited
4036 normally" if we are in batch mode. This allows a GDB which
4037 executes a program on a target system, to behave like a Unix
4038 command (input from stdin, output to stdout, no extraneous
4039 output).
4040
4041 * main.c (main): Allow additional machine-dependent command line
4042 options to be specified with the ADDITIONAL_OPTIONS,
4043 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
4044 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
4045 processing to occur just before the main loop with
4046 BEFORE_MAIN_LOOP_HOOK.
4047 (main): If a "core file" argument is specified, and it is not a
4048 core file, try it as a process ID to attach.
4049 (symbol_completion_function): Attempt to cope with
4050 "show screen-" TAB, not very successfully. This needs more work,
4051 FIXME.
4052 (batch_file): New function, returns whether we are reading
4053 commands from an interactive tty on stdin, or from somewhere else.
4054 Called by normal_stop since it doesn't get from_tty passed down
4055 to it like many commands do.
4056
4057 * remote-nindy.c: Handle command line options for nindy
4058 connection.
4059 (nindy_before_main_loop): Prompt user for tty name if they
4060 don't specify it before getting to the interactive command loop.
4061
4062 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
4063 and -r command line options. Also add hook before main loop
4064 to make it easy to specify a tty.
4065
4066 * TODO: More things to do, one done.
4067
4068 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
4069
4070 * dbxread.c: Make complaint() calls pass pointer, not struct.
4071 Add complaints about badly formatted C++ type information
4072 (const/volatile indicator, and parse errors resulting in
4073 error_type). Fix C++ virtual member fn comment.
4074 (read_struct_type): Avoid bumping pointer if we got a parse
4075 error; this prevents our walking beyond the end of a string.
4076 Terminate loop on null char as well as semicolon.
4077 (process_one_symbol): Fix the LBRAC fix so that it uses the
4078 last previous SLINE, FUN, or SO record's PC address. C++ debug
4079 symbols did not have SLINE records in a useful order compared
4080 to the LBRAC records.
4081 (define_symbol): Handle "catch" records.
4082
4083 * symtab.c (check_stub_type): Added new complain
4084 `stub_noname_complain' and added a consistency check to
4085 keep the debugger from crashing when finishing from an
4086 exception frame. A real fix will be needed later.
4087
4088 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
4089
4090 * infcmd.c (attach_command): Make global.
4091
4092 * Makefile.dist (REMOTE_OBS): Make these compile by default,
4093 but make them easy to comment out. Perhaps later they should
4094 be enabled by what CPU you configure for? FIXME.
4095 (VERSION): Roll to 3.93.
4096 (pinsn.o): Remove rule for obsolete file.
4097 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
4098
4099 Run down a problem that manifested by printing the wrong function
4100 name in stack traces of read_ofile_symtab. Turned out that the
4101 problem was the SunOS 4.1.1 (and previous) C compiler outputs
4102 the LBRAC symbol with an address in the *data* segment, which
4103 blew our binary search through the blocks.
4104
4105 * dbxread.c: Use the complain() facility consistently to bitch
4106 about problems in the symbol file we are reading.
4107 (finish_block): Add code to check the nesting of the blocks;
4108 complain and Procrust them to fit if wrong.
4109 (make_blockvector): Check the order of the blocks, complain
4110 [but don't cope] if wrong.
4111 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
4112 symbols to be sure their PC value is greater than the last SLINE
4113 (line number) symbol we've seen, complaining and adopting the
4114 SLINE PC value if wrong.
4115
4116 * symfile.h (struct complaint, complaint_root, complain,
4117 clear_complaints): Add.
4118 * symfile.c (complain, complaint_root, clear_complaints): Add
4119 facility to deal with non-fatal complaints and to regularize their
4120 suppression.
4121 (symbol_file_add): Clear complaint counters to allow new complaints.
4122 (initialize_symfile): Add 'set complaints' and 'show complaints'.
4123
4124 * dbxread.c (dbx_symfile_read): Remember the address and size
4125 of the string table for the main symbol file, so we won't read it
4126 more than once.
4127 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
4128 to avoid reading the string table yet again. Lint.
4129 (throughout): Improve filtered output, including word wrap.
4130 (read_range_type): Improve Bothner's fix to handle other types too.
4131
4132 * utils.c: Improve line wrap implementation. Handle unlimited
4133 width by making chars_per_line unsigned.
4134 (puts_filtered): New, easy, function.
4135
4136 * defs.h (puts_filtered): add.
4137
4138 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
4139 call the identical sort_symtab_syms() in symfile.c instead.
4140
4141 * expread.y: Suggest the `file' command rather than `symbol-file'.
4142
4143 * command.h (enum var_types): Add zinteger for seroable
4144 unsigned integer.
4145 * command.c (do_setshow_command): Handle var_zinteger. Restructure
4146 nested if's into a switch.
4147
4148 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
4149 we did not stop because of a breakpoint (it must have been for
4150 some other reason, like a "stepi"), so don't print anything.
4151
4152 * symtab.c: Include <sys/types.h> all the time. Now that BFD
4153 doesn't include <sys/types.h>, old SunOS's require it for
4154 <sys/stat.h>.
4155
4156 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
4157
4158 A test port of gdb-3.92.6 to the Sony NEWS.
4159
4160 * Makefile.dist
4161 Don't normally link in remote- or vx stuff.
4162 Some of it doesn't compile, and it wastes space for 99% of the users.
4163 Remove reference to no-longer-used HAVE_VPRINTF.
4164 Fixed BFD_DEP typo to BFD_DIR.
4165 * dbxread.c
4166 Fix cast in arg to bfd_h_getlong.
4167 Make char *prefix be const.
4168 Fix how certain range types are mapped into builtin unsigned int types.
4169 * infrun.c
4170 Remove 2 #includes. They cause errors (on Sony, at least),
4171 and aren't needed (they wern't in earlier versions).
4172 * printcmd.c
4173 print_address_symbolic should never demangle labels
4174 (since it prints *assembler-level* labels).
4175
4176 [This was superseded by the change to printcmd below.]
4177
4178 * utils.c
4179 Add some "volatile" return types to avoid warnings.
4180 If MISSING_VPRINTF add vprintf function and not just macro
4181 (since vprintf is used in printcmd.c).
4182 * valprint.c
4183 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
4184 (The latter isn't grokked by some PCC-based compilers.)
4185
4186 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
4187
4188 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
4189 * nindy-share/coffstrip.c
4190 Added some forward declarations (otherwise, gcc complains
4191 about implicit extern redefined as static).
4192
4193 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
4194
4195 Changes inspired by Per Bothner:
4196 * printcmd.c (print_address_symbolic): Take additional parameter
4197 specifying whether to demangle.
4198 (print_address): Pass in asm_demangle to control demangling.
4199 (print_address_demangle): New fn, takes explicit arg to control
4200 demangling.
4201 * utils.c: Add new vars demangle and asm_demangle, and let them
4202 be set and shown.
4203 (fputs_demangled): If !demangle, just print the argument.
4204 (fprint_symbol): If !demangle, just print raw symbol.
4205 * valprint.c (val_print): Call print_address_demangle rather than
4206 print_address, to cause demangling to depend on the global
4207 rather than assembler-level demangling setting.
4208 * WHATS.NEW, gdb.texinfo: Document.
4209
4210 * main.c (show_command): Show all settings if no arg.
4211 (initialize_main): Make "info set" the same as naked "show".
4212 * command.c (cmd_show_list): Handle prefix commands in the
4213 list, and print the name of the setting as well as its English
4214 description and value.
4215
4216 Allow gdb functions to specify where a line should wrap if it
4217 exceeds the size of a terminal line. Use it to make the output
4218 prettier.
4219 * utils.c (set_screen_width_command): New fn, mallocs a buffer
4220 of the right size when screen width changes.
4221 (set_screensize_command, screensize_info): Remove #if 0'd fns.
4222 (wrap_here): New fn, indicates a point in the output where we
4223 should wrap the line rather than just letting it overflow at a
4224 random place.
4225 (fputs_filtered): Implement wrapping.
4226 (n_spaces): New fn, returns a pointer to N spaces.
4227 (print_spaces_filtered): Use n_spaces.
4228 * defs.h (n_spaces): Declare.
4229 * stack.c (print_frame_info): Wrap with 4-space indent after
4230 fn name and before filename and line number.
4231 * printcmd.c (print_frame_args): Wrap with 4-space indent
4232 before each argument name is printed.
4233 * valprint.c (value_print): Wrap with no indentation before
4234 each repetition.
4235 (val_print_fields): Wrap with indentation relative to nesting
4236 level before each field name.
4237 (val_print): Wrap with nesting indentation before array elements.
4238 * command.c (do_setshow_command): Avoid extra newlines,
4239 wrap with 4-space indent around values printed, end with period.
4240 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
4241
4242 * breakpoint.c (breakpoint_1): Implement addressprint for
4243 "info breakpoints" display. Change file name and line number
4244 format to " at file:nnn" rather than " (file line nnn)".
4245 * gdb.texinfo: Document.
4246
4247
4248 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4249
4250 Frozen for gdb-3.92.6 release.
4251
4252 README, WHATS.NEW: Update for 3.92.6 release.
4253
4254 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
4255 coffread.o from configs since it is now built by default.
4256 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
4257 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
4258 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
4259 from configs since it is now built by default.
4260
4261 Makefile.dist: Update for release 3.92.6. Handle files that
4262 have been moved to ../include, ../getopt, or ../bfd. Add
4263 saber.suppress and tests directory. Add config.status to
4264 the release (it will say "none").
4265
4266 coredep.c: Minor formatting fixes.
4267
4268 These changes were made in early December but only checked in now:
4269 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
4270 nindy-share/nindy.c: lint
4271 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
4272 register values coming back from the target; we store values
4273 in target byte order everywhere.
4274
4275 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
4276
4277 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
4278
4279 * valprint.c (cplus_val_print, val_print_fields): New functions,
4280 which print C++ objects. They conspire to avoid printing a
4281 virtual base class more than once, following all the twists and
4282 turns of C++ virtual base rules.
4283 (val_print): Call the above rather than do it by hand.
4284
4285 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
4286 symbol file, not for added files like shared libs. This really
4287 needs to be generalized to a timestamp per file.
4288
4289 * core.c (cleanup_core): Avoid coredump if no core file.
4290
4291 * config.gdb: Accept -host or -target in place of +host or
4292 +target.
4293
4294 * coffread.c (find_linenos): Avoid desupported BFD interface
4295 to line numbers. We still read them manually rather than using
4296 BFD's "generic" features.
4297
4298 * gdbrc.tex, threecol.tex: Add GDB reference card and its
4299 formatting code.
4300 Makefile.dist: Add refcard to OTHERS list for creating tar files.
4301
4302 * Makefile.dist: Eliminate use of $< in explicit targets.
4303
4304 * readline/Makefile: Use $< rather than $*.c, which does not
4305 include the VPATH in GNU Make.
4306
4307 * tconfig/i960-bout, tconfig/i960-coff: These are identical
4308 copies of tconfig/i960, added for global configuration
4309 compatability. All i960 versions can read both coff and b.out.
4310
4311 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
4312 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
4313 automaticaly.
4314
4315 * TODO: Think of more things to do.
4316
4317 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
4318
4319 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
4320 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
4321 64-bit float conversion.
4322
4323 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
4324 equivalent to sun?os4 so global config works.
4325
4326 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
4327
4328 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
4329
4330 * main.c: Only declare linesize once; declare pagesize not at
4331 all, since it is never used.
4332 (main): Clear newly allocated line before it is used.
4333
4334 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
4335
4336 Further stabilization for the Intel 960.
4337
4338 * Makefile.dist: Parameterize the location of the "include"
4339 and "bfd" directories, as well as "getopt". Add symfile.c.
4340 Link in both dbxread and coffread. Fix up "make depend" to
4341 rewack the locations of include, bfd, and getopt in its output.
4342
4343 * README: Document moving include files, improve some of
4344 the other doc.
4345
4346 * coffread.c: Move common code out to symfile.c. Change
4347 symbol_file_command style interface to use new *_symfile_init
4348 and *_symfile_read interface under BFD. Use BFD internal
4349 info to locate line table, symbols, etc.
4350
4351 * core.c (core_fetch_registers): Rename to get_core_registers
4352 to avoid confusion with fetch_core_registers.
4353 (register_addr): Move to coredep.c, which is already machine
4354 dependent. This leaves core.c pretty clean of dependencies.
4355
4356 * coredep.c (register_addr): Accept this routine from core.c.
4357
4358 * dbxread.c: Move common code (with coffread.c, etc) into new
4359 symfile.c. Each psymtab now contains a pointer to the
4360 format-dependent function that knows how to read it in. Make
4361 some things static.
4362 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
4363 (process_one_symbol): Add code to complain about a "compiler bug
4364 we muzzle here", if we actually see it.
4365
4366 * eval.c (evaluate_subexp): Insert missing "break" statements
4367 in code that determines whether a variable is an lvalue in
4368 memory, register, or whatever. I detected this via a compiler
4369 bug in which it *almost* mashed out the whole switch statement.
4370
4371 * gdb-int.texinfo: Add minor sections on configuring gdb for
4372 release, and about the README file.
4373
4374 * infcmd.c (registers_info): Fix formatting somewhat. Still
4375 not as pretty as before, but it handles byte swapping.
4376
4377 * remote-nindy.c: If data cache routines are interrupted while
4378 waiting for the remote end, be sure that any uninitialized cache
4379 blocks are on the free list, not on the valid list!
4380
4381 * symfile.h: Flesh out this header file with all the various
4382 routines and variables that have been merged in from dbxread.c
4383 coffread.c, and symtab.c to symfile.c.
4384
4385 * symfile.c: New file, containing code common to dbxread.c,
4386 coffread.c, and some code from symtab.c. All generic code for
4387 reading symbol files should be in here now.
4388 (unrecord_misc_function): Remove unused function.
4389
4390 * symtab.h: Remove file-reading things to symfile.h.
4391
4392 * symtab.c: Remove file-reading things to symfile.c.
4393
4394 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
4395 to decode i960 fault types.
4396
4397 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
4398 target.c: Change type of the "resume" function from int to void,
4399 since its result was never used.
4400
4401 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
4402
4403 * main.c: Replace "stupid" with "caution"; you now "set caution
4404 on or off".
4405
4406 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
4407
4408 * infcmd.c (do_registers_info): Call val_print to deal with the
4409 byte order of the registers being printed. FIXME, this makes
4410 the formatting of the output uglier.
4411
4412 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
4413 defined, call it for signals the debugger doesn't itself use.
4414 The i960 uses this for more detailed fault information.
4415
4416 * remote.c (remote_open): If arg is null, print help rather than
4417 dumping core.
4418
4419 * sparc-xdep.c (register_valid): Avoid declaring size, since
4420 various modules will think of various sizes depending on the
4421 architecture of their tm-file. FIXME, we need protection against
4422 actually entering one of those modules, which would clobber
4423 storage if not for the target architecture compiled into gdb.
4424
4425 * stack.c (up_command, down_command): Always print the frame
4426 you arrive at.
4427 (up_silently_command, down_silently_command): New commands
4428 for use in scripts.
4429
4430 * i960-pinsn.c (reg), i960-tdep.c: Lint.
4431
4432 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
4433 more parameters than it used to.
4434
4435 * findvar.c (registers): Increase slop to 256 bytes, which should
4436 protect us against even most RISC machines with large register
4437 sets.
4438 (locate_var_value): Move declaration inside related ifdef.
4439
4440 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
4441 throughout, to avoid throwing away buffered input from the board.
4442 (nindy_wait): Supply_register takes addr_of_value, not value.
4443 (i960_print_fault): Renamed from i80960_fault.
4444 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
4445 (nindy_store_registers): Avoid regs_changed stuff, just stuff
4446 them.
4447 (nindy_create_inferior): Don't bother to write PC_REGNUM since
4448 we can set the PC in the call to proceed(). Unpush nindy_ops
4449 before pushing it on top, to avoid message to user. Eliminate
4450 commentary from Unix machines that just misleads here.
4451 (reset_command): Fix error message to suggest target command.
4452
4453 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
4454
4455 Release 3.92.5 as frozen.
4456
4457 Stabilize the merged release...with help from lint, Saber C,
4458 gcc -W, etc.
4459
4460 Everywhere: Add include files needed to declare return types
4461 of functions called.
4462
4463 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
4464
4465 * breakpoint.h: Add undeclared breakpoint functions, and some
4466 functions for display handling since I couldn't think of a better
4467 .h to put them in.
4468
4469 * breakpoint.c (insert_breakpoints): Make code for disabling
4470 shared library bkpts more likely to work. It's used when we
4471 rerun a program and stop before the shared library has been
4472 mapped in.
4473 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
4474 cast from pointer, so it squeezes through catch_errors.
4475 (bpstat_stop_status): Fix logic broken some time ago. We now
4476 always create a bpstat if the stop address matches a breakpoint,
4477 even if we don't stop there -- just like the old code used to do
4478 before I got my fingers into it (sigh).
4479 (breakpoint_1): Print "ignore count" after "stop only if"
4480 condition, since that's how it actually works.
4481 (mention): Handle watchpoints as well as breakpoints.
4482 (watch_command): use set_raw_breakpoint and mention to do most
4483 of the work (and initialize all the fields!). Only pass one
4484 arg to parse_c_expression, since that's all it takes.
4485
4486 * command.c (not_just_help_class_command): Rename arg to args
4487 since we ignore "unused argument" warnings on vars named "args".
4488 inflow.c (child_terminal_info): ditto.
4489 infptrace.c (kill_inferior): ditto
4490 main.c (catch_errors, version_info, quit_command, pwd_command,
4491 source_command, dump_me_command, editing_info,
4492 set_history_size_command, set_history, show_history,
4493 set_verbose): ditto
4494 stack.c (locals_info): ditto
4495 target.c (target_files_info): ditto
4496 valprint.c (set_input_radix, set_output_radix): ditto
4497
4498 * core.c: Remove old variables for handling core and exec file
4499 sections (data_start, data_end, stack_start, stack_end,
4500 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
4501 text_end, exec_data_start, exec_data_end, text_offset,
4502 exec_data_offset, data_offset, stack_offset). They're
4503 superseded the more general build_section_table and
4504 xfer_memory.
4505 (get_exec_file): Mention the `file' command.
4506 (read_memory_check): Rename to memory_error, and only call it
4507 in the case of an actual error.
4508 (read_memory, write_memory): call memory_error.
4509 (core_fetch_registers): Register section name is ".reg".
4510
4511 coredep.c: Remove a bunch of crud now that all this file does
4512 is pull the registers out of a core file.
4513 (fetch_core_registers): Rewrite to actually work, I hope.
4514
4515 dbxread.c: Use a.out.gnu.h, not system a.out, now.
4516 Replace index() with strchr(). Remove all the pre-BFD macro
4517 definitions for accessing the symbol file.
4518 (struct dbx_symfile_info): Encapsulate the information that
4519 dbx_symfile_init needs to pass to dbx_symfile_read in this
4520 struct.
4521
4522 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
4523 dbx_symfile_discard): Rearrange symbol file reading to divide
4524 the format-specific part from the format-independent part,
4525 leaving the format-independent part such as file name expansion
4526 and opening in symtab.c. This replaces
4527 partial_symbol_file_open and partial_symbol_file_read.
4528 Symbol_file_read, add_file, add_file_target_command,
4529 add_file_addr_command move to symtab.c. Pass an explicit
4530 "mainline" flag for when reading the main symbol table, rather
4531 than relying on the offset address to be zero or nonzero.
4532
4533 (dbx_symfile_read): Don't allow void *'s to be printed as
4534 typedefs.
4535 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
4536 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
4537 macro" debug version really work.
4538 (read_dbx_symtab): Remove unref'd parameter inclink.
4539 Avoid swapping N_SLINE symbols, for speed.
4540 Merge N_TEXT!N_EXT case with the other external symbol
4541 definitions' case. Add comments.
4542 (start_psymtab): Allocate the symfile name in the psymtab on
4543 the psymbol_obstack, rather than using the caller's storage.
4544 (end_psymtab): Only allocate a dependencies list if there are
4545 more than zero.
4546 (psymtab_to_symtab_2): Use BFD when reopening file to read
4547 its symbols for real.
4548 (read_struct_type): Add FIXME comments where it needs work
4549 for C++ bogosity.
4550 (read_huge_number): Add FIXME about overflows.
4551 (read_range_type): Add FIXME about comparing a long to 1<<32.
4552
4553 * coffread.c: Minor changes to move things closer to the new
4554 regime with symtab.c and dbxread.c Major work is still needed
4555 here.
4556
4557 * exec.c (exec_file_command): Remove old variables (see core.c
4558 above).
4559 (xfer_memory): If memory transfer is right at the end of a
4560 section, don't lose.
4561
4562 * findvar.c (get_saved_register): If value is in a real
4563 register, LVAL is lval_register, not lval_memory.
4564
4565 frame.h: Declare print_sel_frame and record_selected_frame.
4566
4567 gdb-int.texinfo: New file, for GDB internals documentation.
4568 Very simple, unformatted doc of cleanups is there for now.
4569
4570 gdbcore.h: Remove obsolete variables that described a.out
4571 section addresses and offsets. (See core.c above.)
4572 Declare fetch_core_registers and registers_fetched.
4573
4574 getopt.c: Declare char *alloca(); even on SPARC.
4575
4576 infcmd.c (run_command): Call target_kill rather than
4577 kill_inferior.
4578 (step_command, next_command, stepi_command, nexti_command):
4579 Declare from_tty parameter even though we don't use it.
4580 (run_stack_dummy): argument BUFFER is a char array, not
4581 a pointer to REGISTER_TYPE.
4582 (finish_command): using_struct_return needed a value *,
4583 not a struct symbol *.
4584
4585 * infptrace.c (child_xfer_memory): To avoid dependency on
4586 where sections are in memory, try PT_WRITE_D and if that fails,
4587 try PT_WRITE_I. Most Unixes don't care which you use.
4588
4589 * infrun.c (step_resume_break_shadow): Change to array to
4590 match other breakpoint shadow storage.
4591 (clear_proceed_status): Pass address of bpstat to
4592 bpstat_clear, not the bpstat itself.
4593 (child_create_inferior): FIXME comment about if the child
4594 exits.
4595 (start_inferior): Remove old function.
4596 (child_open): Use target_kill rather than kill_inferior.
4597 (wait_for_inferior): Ditto.
4598 (insert_step_breakpoint, remote_step_breakpoint): Use
4599 new step_resume_break_shadow.
4600
4601 * inftarg.c (child_wait): If all child processes die,
4602 pretend that the one being waited for exited with signal 42.
4603
4604 * main.c (command_line_input): When scanning for comments,
4605 don't coredump on unclosed quotes.
4606 (quit_command): Use target_kill rther than kill_inferior.
4607 (_initialize_main): Rename class_user from "user" to
4608 "user-defined".
4609
4610 * printcmd.c (print_command_1): Initialize "fmt" if no format
4611 is specified by the user.
4612 (print_frame_args): Only add to args_printed if we are
4613 actually fetching args from the stack (avoiding undefined
4614 arg_size).
4615 (_initialize_printcmd): Remove bogus \{ from string.
4616
4617 * remote-eb.c (eb_open): Avoid coredump on no argument.
4618
4619 * remote-nindy.c: Bring out of Intel environment into new
4620 target environment. Remove all conditional compilation on
4621 I80960. Massive hacking throughout.
4622 (nindy_xfer_inferior_memory): New routine stolen from
4623 infptrace.c.
4624 (nindy_create_inferior): New routine pieced together, probably
4625 not quite working yet.
4626 (nindy_ops): New target_ops struct for nindy.
4627
4628 * remote-vx.c: Use write_memory rather than target_write_memory
4629 to get error checking.
4630 (vx_add_file_command, vx_open): Use symbol_file_add rather than
4631 add_file.
4632 (vx_create_inferior): Use target_terminal_ours...
4633
4634 * signame.c (_initialize_signame): Always initialize, since
4635 we need the table for things other than psignal.
4636
4637 * solib.c (solib_add): Use symbol_file_add, not add_file.
4638 (solib_address): Return boolean result rather than struct
4639 pointer which nobody else knows the type of.
4640
4641 * sparc-tdep.c, valops.c: Use write_memory rather than
4642 target_write_memory, to get error checking.
4643
4644 * stack.c (locals_info, catch_info, args_info,
4645 get_selected_block, frame_command, up_command): Use
4646 target_has_stack, rather than have_inferior_p or
4647 have_core_file_p.
4648
4649 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
4650
4651 * symfile.h: New file, defining the interface between the
4652 generic and object-file-specific symbol reading code.
4653
4654 * symtab.c: Move generic symbol-reading interface to symtab.c,
4655 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
4656 table to map BFD targets to symbol-reading modules in GDB.
4657 Change index to strchr.
4658 (lookup_struct_elt_type): Use error() rather than hand-made
4659 simulations thereof.
4660 (lookup_partial_symbol): Speedup slightly when length == 0.
4661 (symbol_file_add): New function.
4662 (symbol_file_command): Call it.
4663 (symfile_open, symfile_init): New function.
4664 (add_file_target_command, add_file_addr_command): moved from
4665 dbxread.c.
4666
4667 * target.c (target_command): use target_kill.
4668
4669 * target.h (target_files_info): Don't declare, never called
4670 from outside.
4671
4672 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
4673 files to determine stack end address.
4674
4675 * valarith.c (value_x_binop, value_x_unop): Change error message
4676 to be more useful. Pass proper argument to value_struct_elt.
4677
4678 * valops.c (value_assign): FIXME comment that long long
4679 bitfields will break here.
4680
4681 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
4682 Update `make saber_gdb' to work better.
4683
4684 * TODO: A woman's work is never done.
4685
4686 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
4687 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
4688 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
4689 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
4690 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
4691 valops.c, valprint.c, exec.c: Lint.
4692
4693
4694 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
4695
4696 Continuing Intel 960 port merge of GDB.
4697
4698 * Makefile.dist: Merge i960 "nindy-share" files. Rename
4699 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
4700 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
4701 Wack over "make depend" so it handles files in subdirectories
4702 vx-share, nindy-share, bfd, and in the current directory.
4703
4704 * blockframe.c (get_prev_frame_info): Remove fatal error
4705 if stack not defined.
4706
4707 * core.c (core_open, core_detach): New functions that handle
4708 the old "core-file" command as "target core" and "detach" instead.
4709 (core_file_command): Call them.
4710 (core_xfer_memory): Use common routine xfer_memory.
4711
4712 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
4713 dbxread now uses bfd for everything but symbol reading itself.
4714 BFD internals are used to drag out the relevant file offsets.
4715 (partial_symbol_file_open): Change args all around for BFD.
4716
4717 * symtab.c: Rename "value" to "val" everywhere, so we can
4718 #include "value.h".
4719 (symbol_file_command): New command, moved from dbxread.c
4720 and coffread.c. It uses BFD to read the file, then vectors
4721 based on its type, to dbx or coff symbol readers.
4722 * symtab.h: Extern a few vars for symbol_file_command.
4723
4724 * target.h: Breakpoint takes a char * save area, not a char **.
4725
4726 * valprint.c (val_print): When unpacking bitfields, offset
4727 the address in gdb of the value, if it is declared with a shorter
4728 type. Remove the last "runtime kludge test" of host byte order.
4729
4730 * utils.c: Remove old my_bfd_read routine.
4731
4732 * stack.c (frame_info): Use target_has_stack. Print program counter
4733 register's actual name rather than "pc", since it's called the
4734 "ip" (instruction pointer) on the i960 (sigh).
4735
4736 * target.c (target_command): Add command for selecting a target
4737 type and calling its open routine. This is used for initiating
4738 communication with a particular target, in a generic way.
4739
4740 * tm-i960.h: Update for modern gdb. Remove semicolons from
4741 various macros. Handle reading struct return convention, and
4742 error-out attempts to return structs with the "return" command.
4743 Be sure gdb doesn't think we know how to call functions in the
4744 inferior.
4745
4746 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
4747 to i960_xxx in lower case.
4748 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
4749 not being defined yet.
4750
4751 * remote.c (remote_open): Call start_remote to initialize
4752 wait_for_inferior during open.
4753 (remote_xfer_inferior_memory): Return length written rather
4754 than errno value.
4755
4756 * remote-vx.c (target_command -> vx_open): Use new generic
4757 target command.
4758 * remote-eb.c, inftarg.c, exec.c: ditto.
4759
4760 * infrun.c: Fix comments.
4761 (attach_program -> child_open): Use new generic target command.
4762 (wait_for_inferior): Clear saved register values before target_wait,
4763 so target_wait can set some of them if convenient.
4764
4765 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
4766 Return success indicator, not void.
4767 (child_xfer_memory): Avoid fetching initial word if we'll
4768 overwrite it anyway.
4769
4770 * infcmd.c (attach_command): Use new generic target open routine.
4771 (_initialize_infcmd): Update doc on attach and detach commands.
4772 (do_registers_info): Merge in a byte-order problem as a FIXME
4773 comment.
4774
4775 * findvar.c (find_saved_register): Avoid problem in current frame.
4776 (read_relative_register): Ditto.
4777 (write_register): Convert byte order on the way out.
4778
4779 * exec.c (file_command): Add.
4780 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
4781 (xfer_memory): Common function between core_xfer_memory and
4782 exec_xfer_memory.
4783 (exec_xfer_memory): Use it.
4784
4785 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
4786
4787 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
4788 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
4789 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
4790
4791 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
4792
4793 Merge Intel 960 port of gdb, continuing...
4794
4795 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
4796 symbol_file_command): Pass from_tty arg to hush 'em up.
4797
4798 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
4799 Add magic numbers for 960 COFF format.
4800

4809 Remove temp file if download is interrupted.
4810
4811 Wed Aug 1 09:08:33 PDT 1990
4812 Now uses binary protocol to talk to NINDY.
4813 Old hex protocol (NINDY 2.13 and older) supported with -O switch.

4818 Source code reorganization.
4819
4820 Thu Apr 26 11:09:55 PDT 1990
4821 More cleanup of batch mode; specifically, execute "-s", "-e", and
4822 "-se" switches as soon as they are encountered on the invocation line.
4823
4824 Fri Apr 20 13:47:15 PDT 1990
4825 Add -brk switch.
4826
4827 Thu Apr 19 09:54:28 PDT 1990
4828 Add 'reset' command.
4829
4830 Wed Apr 18 09:48:07 PDT 1990
4831 After opening remote tty, wait for 1 second to go by without input
4832 from it before trying to talk to NINDY (fixes problems with the
4833 Heurikon HK80/V960E).
4834
4835 Mon Apr 4 16:33:05 PDT 1990
4836 Some output was not being suppressed in 'batch' mode.
4837
4838 Thu Mar 22 15:31:11 PST 1990
4839 Ask user if old symbol table should be deleted when new file is
4840 downloaded.
4841
4842 Allow user to run a program downloaded before gdb960 was brought up.
4843
4844 Correct "exec-file" help message for i80960 context.
4845
4846 Correct bug in calculating user space address: could occasionally
4847 corrupt user program.
4848
4849 Make sure to zero low-order bits in rip's because of bug in 960CA
4850 A-step part: could cause operation faults when "next"ing across
4851 a function call.

4862
4863 Mon Oct 23 12:03:04 PDT 1989
4864 Use G960BASE and G960BIN environment variables to find 'sx' utility.
4865
4866 Mon Oct 16 14:15:09 PDT 1989
4867 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
4868
4869 Mon Oct 2 15:56:31 PDT 1989
4870
4871 Added 960CA disassembly support.
4872
4873 To simplify maintenance:
4874 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
4875 directly instead.
4876 - eliminated opcode.h: incorporates tables into i960-pinsn.c
4877 - moved 960-specific routines from i960-pinsn.c to i960-md.c
4878 - made disassembly interface identical to that in gdmp960.
4879
4880
4881
4882 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
4883
4884 * target.h: Allow targets to stack. Add target_has_memory,
4885 _registers, etc. Restructure memory access and "info files"
4886 to walk the target stack.
4887 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
4888 target.c: Change tables to match target.h.
4889 * inflow.c (child_mourn_inferior): pop child_ops.
4890 (generic_mourn_inferior): Use new has_stack flag.
4891 * infptrace.c (child_xfer_memory): New memory regime.
4892 * inftarg.c (child_files_info): New "info files" regime.
4893 * remote-eb.c: New memory regime, new info files.
4894 * remote-vx.c: New memory regime, new info files. Now use
4895 separate targets for VxWorks attachment to machine, and
4896 actually running a process under VxWorks, since one has
4897 stack & execution & regs and the other doesn't.
4898 * remote.c: New memory regime, new info files.
4899 * sparc-xdep.c (fetch_core-registers): New memory regime.
4900 * target.c: New routines and support for stacked targets,
4901 new memory regime, new info files regime.
4902
4903
4904 Generalize section handling for an arbitrary number of sections,
4905 including use of the new BFD (binary file) library.
4906 * gdbcore.h: Add struct section_table.
4907 * exec.c (build_section_table): Iterate all sections and
4908 record what gdb needs to know about them.
4909 (exec_command): Use it.
4910 (exec_xfer_memory): Use the table.
4911 (exec_files_info): Print the table.
4912 * core.c (core_file_command, core_xfer_memory, core_files_info):
4913 Likewise.
4914 * source.c (find_source_lines): Use bfd_get_mtime.
4915 * dbxread.c: Quick changes to make it compile with new BFD.
4916 * utils.c (error): Avoid using bfd_error in generic routines.
4917
4918 * core.c (core_fetch_registers): Get from the ".regs" section of
4919 the BFD core file.
4920 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
4921
4922 * inferior.h (attach_flag): Export.
4923 * infcmd.c (run_command): use new target_create_inferior.
4924 * infrun.c (child_create_inferior): Don't return result.
4925 * Makefile.dist (VERSION): 3.91.4.
4926
4927 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
4928
4929 * breakpoint.c (bpstat_num): Handle breakpoints which have
4930 since been deleted, such as temporary breakpoints.
4931 infcmd.c (program_info): ditto.
4932
4933 * core.c (core_file_command): Display the frame where the core
4934 dump occurred.
4935
4936 * main.c: lint.
4937
4938 * remote-vx.c (target_command): Merge in target command from
4939 targ-vx.c. A few other cleanups.
4940
4941 * TODO, Projects: Lots more stuff to do...
4942
4943 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
4944
4945 Massive changes to wall off the remote-debugging interface
4946 behind a function vector. The port to handle VxWorks targets
4947 is also part of this.
4948
4949 All files: Replace references to renamed functions,
4950 remove references to remote_debugging, remove references to
4951 have_include_file, have_core_file in favor of target_has_stack,
4952 target_has_memory, etc.
4953
4954 * Modularize the breakpoint interface.
4955 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
4956 a breakpoint instruction.
4957 breakpoint.c: struct breakpoint's shadow_contents now sized as
4958 BREAKPOINT_MAX.
4959 (insert_breakpoints): Vector to target to install breakpoints.
4960 (remove_breakpoints): Vector to target here too.
4961 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
4962 sparc-tdep.c (single_step): Use new breakpoint interface for
4963 the single-step breakpoints.
4964 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
4965 New file, contains routines to insert and remove breakpoints by
4966 reading out the old contents and later replacing them. This is
4967 how ptrace breakpoints work, and many remote systems as well.
4968
4969 * tm-vxworks68.h: New config file, overrides a few things for
4970 Wind River's preferences.
4971
4972 * target.h: New file, for transfer vector used to talk to the
4973 inferior (child, attached, core, exec, remote, etc). All accesses
4974 to the thing being debugged should come through these vectors.
4975 target.c: New file, routines to handle transfer vector.
4976 (various files): Add transfer vectors XXX_ops for the various
4977 targets and pseudo-targets (core files, etc) we support.
4978
4979 * breakpoint.c (bpstat_stop_status): Further explorations of
4980 watchpoints and why things don't work all the time.
4981 (bpstat_alloc): New fn to allocate a bpstat and chain it.
4982
4983 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
4984 the local gdbinit if it doesn't already have it.
4985
4986 * core.c (core_ops): add and install.
4987 Allow core debugging without exec file.
4988
4989 * dbxread.c (free_and_init_header_files): Merge two fns.
4990 (end_symtab): Free named symbol table when a new version comes in.
4991 (read_dbx_symtab): Relocate all kinds of symbols with base
4992 address. First step toward handling different text, data, bss
4993 reloc.
4994 (add_file_addr_command): Renamed add_file_command.
4995 (add_file_command): Vector to remote handler.
4996 Add "load" as an alias for "add-file" command.
4997
4998 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
4999 non-returning functions.
5000
5001 * exec.c: Add exec_ops, and push it as a target when an exec
5002 file is specified.
5003
5004 * infcmd.c (run_command): Pass executable file name and arg list
5005 separately when starting an inferior. Permit "run" when no exec
5006 file is specified, for VxWorks.
5007 (detach_command): Move to child_detach in inftarg.c.
5008
5009 * inftarg.c: New file. Unix-child-specific routines, and the
5010 child_ops structure.
5011
5012 * inferior.h (registers): Export "registers" as the way for
5013 target dependent register handlers to find gdb's local copy of
5014 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
5015 since it is now used by places that want wait_for_inferior to
5016 handle the grunge but want to see every trap from the inferior.
5017
5018 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
5019 Eliminate remote_debugging hooks in terminal handling.
5020
5021 * infrun.c: Replace start_inferior with child_create_inferior.
5022 Move all the hair of Unix shells and ptrace idiosyncracies into
5023 child_create_inferior, so remote handlers don't have to deal.
5024 Remove running_in_shell. Rename stop_after_attach to
5025 stop_soon_quietly, and use it in a few other places where we want
5026 to just call wait_for_inferior and get control back on the first
5027 trap. trap_expected now never takes a value > 1.
5028 (init_wait_for_inferior): Initialize static vars when a new
5029 process is created.
5030
5031 main.c (gdbinit): Add new hook for .gdbinit file name, let
5032 it be overridden by config files as GDBINIT_FILENAME.
5033 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
5034 Both of these are used for VxWorks gdb.
5035
5036 mcheck.c: rename include file "gmalloc.c" to avoid problems
5037 with system include file "malloc.c".
5038
5039 param-no-tm.h: New include file, same as param.h but does not
5040 include the default "tm.h" file. This is used in files where
5041 the target is known, e.g. remote-eb.c or sparc-xdep.c.
5042
5043 param.h: Now just a shell that includes tm.h and param-no-tm.h.
5044
5045 remote-vx.c: New file, VxWorks remote debugging support. Uses
5046 RPC routines that are shared with the target system, in directory
5047 ${srcdir}/vx-share.
5048
5049 remote.c: Vectorize remote interface.
5050
5051 source.c: Globalize source_path, and make an alias "l" for "list"
5052 since we now have the "load" command.
5053
5054 sparc-xdep.c: Use new param-no-tm.h.
5055
5056 symmisc.c (free_named_symtab): Add new function from Wind River.
5057 However, ifdef it out for now while we think about what it should
5058 really be doing.
5059
5060 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
5061 PREPARE_TO_STORE to
5062 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
5063 non-Unix-children handle this with their own code in the target
5064 transfer vector.
5065
5066 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
5067 source and target lists. Add vx-share to default list of include
5068 directories. Add new files to src and target lists: mem-break,
5069 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
5070 ${srcdir} versions of munch and createtags are used.
5071
5072 * valops.c (find_function_addr): Split out of call_function.
5073 (call_function_by_hand): Rename call_function; this function
5074 calls functions in the target by laboriously patching the target
5075 word-by-word with the right stack, args, regs, etc.
5076
5077
5078 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
5079
5080 Handle AMD 29000 a bit better.
5081
5082 * remote-eb.c (readchar): Mask received char log to make it readable.
5083 (remote_start): Pass arguments down to executing program.
5084 Make startaddr unsigned.
5085 infrun.c (start_inferior): Accept args, pass them to
5086 remote_start.
5087 infcmd.c (run_command): Pass args down to start_inferior.
5088
5089 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
5090 the target object file format.
5091 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
5092
5093 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
5094 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
5095
5096 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
5097
5098 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
5099 * TODO: We did a few things, we have more to do though.
5100
5101 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
5102 * inflow.c (inferior_died): Clear deferred stores.
5103
5104 * Debug problems with dummy frames and calls to the inferior.
5105 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
5106 * sparc-tdep.c (do_restore_insn): Simplify.
5107 (sparc_frame_find_saved_regs): Simplify and fix what we find.
5108 (sparc_push_dummy_frame): Simplify and fix what we push.
5109 (sparc_pop_frame): Slightly more hair here, deciding whether
5110 we are restoring a saved PC or returning to a return address in %i7.
5111 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
5112
5113 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
5114 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
5115 * obstack.h (chunkfun): ditto.
5116 * defs.h (xmalloc, xrealloc): ditto
5117
5118 * utils.c (quit): Grab the terminal from the child if necessary.
5119
5120 * inflow.c (term_status_command): Rename to term_info, change
5121 to "info terminal".
5122
5123 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
5124 (is_delayed_branch): Speed up.
5125 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
5126 Still missing some float ops, and needs testing.
5127
5128 * Support for input and output radixes other than base 10
5129 * defs.h (input_radix, output_radix): Declare.
5130 * expread.y (yyparse, parse_number): Handle changes of input
5131 radix, and ambiguous names-or-numbers in radixes >10.
5132 * printcmd.c (print_scalar_formatted): Print formatted hex
5133 numbers in varying column widths.
5134 * valprint.c (val_print): Use output_format to print scalar ints.
5135 (set_input_radix, set_output_radix, set_radix): Create.
5136 (set_output_radix): Set output_format from output_radix.
5137 (_initialize_valprint): add `set radix' but leave the others off.
5138
5139 * main.c (execute_command): Let stupid questions be turned off.
5140 (_initialize_main): Handle "set stupidity", etc.
5141
5142 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
5143 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
5144
5145 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
5146
5147 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
5148 bfd stuff is still screwed up, but with some manual work, it
5149 compiles.
5150
5151 * breakpoint.c (bpstat_do_actions): Start over if a command
5152 proceeds the inferior, since the inferior will have stopped and
5153 will need to have its new stop-actions taken care of.
5154
5155 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
5156 compiler fits, simplify it.
5157
5158 * gdb.texinfo (directory command): Doc new dir command.
5159 source.c (directory_command): "dir" now puts things on the front
5160 of the path, moves dups up front, and handles multiple names
5161 on the command line, inserting each one in order. It also
5162 blows away cached line and full_filename info.
5163
5164 * stack.c (backtrace_command): Skip "more stack frames follow"
5165 unless interactive.
5166
5167 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
5168 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
5169 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
5170 The only odd one was Gould NP1, which had defined vprintf to
5171 "printf"!!!
5172
5173 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
5174 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
5175 variable, inspect_it.
5176 valprint.c (print_string, val_print): Use the global inspect_it
5177 to indicate whether to print in Epoch style or normal style.

5179 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
5180
5181 * printcmd.c (call_command): add an alias for the "print" command
5182 which runs expressions and doesn't print the result if void.
5183 (print_command_1): implement it.
5184
5185 * command.c: Remove #if 0'd code. Initialize all the fields
5186 in add_cmd (). Rename do_nothing_command to
5187 not_just_help_class_command, and make it externally visible.
5188 command.h: add user_commands to struct.
5189 * main.c (define_command): Don't overload c->function with a char
5190 string as well as a function pointer.
5191
5192 * eval.c (evaluate_subexp): Reinstall tiemann changes to
5193 calling convention of value_struct_elt () that got dropped in
5194 merge.
5195
5196 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
5197 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
5198
5199 * tm-sparc.h (POP_FRAME): replace some constants with defines.
5200
5201 * sparc-xdep.c (store_inferior_registers): defer stores to regs
5202 until a good time (e.g. when we are about to run the child),
5203 saving ptrace calls.
5204 * infrun.c (proceed): handle DO_DEFERRED_STORES.
5205 * tm-sparc.h: define DO_DEFERRED_STORES.
5206
5207 * sparc-xdep.c (store_inferior_registers): when storing float
5208 registers, don't store stack regs too. When storing the SP,
5209 however, DO store the stack regs too. This fixes a bug in which
5210 the dummy frame is not recognized when a call_function finishes,
5211 because its frame pointer (in the stack regs) was never
5212 initialized.
5213 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
5214 even though we don't know how to read them from an inferior.
5215 valops.c (call_function): Comment about storing SP.
5216
5217 * infrun.c (save_inferior_status): Save away the original bpstat
5218 chain so it can be restored later. Install the copied version for
5219 use by whoever saved the status. It will be blow away by
5220 restore_inferior_status, and the original chain restored. This is
5221 important for people who have pointers into the original.
5222
5223 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
5224 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
5225 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
5226
5227
5228 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
5229
5230 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
5231 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
5232 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
5233
5234 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
5235
5236 * Merge Mike Tiemann's multiple inheritance changes from Sun.
5237 Store the baseclasses in a type struct starting from array element
5238 0 rather than from the unusual array element 1.
5239
5240 dbxread.c: the above.
5241 (virtual_context): Add
5242 Read new debug information about which virtual function table
5243 a virtual function is from, and store it in fn_field.fcontext.
5244
5245 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
5246 TYPE_FN_FIELD_STATIC_P.
5247
5248 symtab.c: the above.
5249 valops.c: the above. Handle pointer casts of object *'s.
5250 (search_struct_method): Add.
5251 (value_struct_elt): First arg is now a pointer to a value, and is
5252 modified on return.
5253
5254 valprint.c: the above.
5255 values.c (value_virtual_fn_field): Add type arg. Handle
5256 offsetting to the proper object when calling virtual fns.
5257 The above.
5258 (baseclass_addr): Add valuep arg.
5259
5260 * README: Document the current state of BFD config (missing).
5261 * TODO, ChangeLog, Makefile.dist: Roll version.
5262 * WHATS.NEW: Add summary of changes since 3.5.
5263
5264 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
5265
5266 * dbxread.c (read_struct_type): Clear bit vectors whenever
5267 we allocate one.
5268 symtab.c (B_CLRALL): define.
5269
5270 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
5271 using == rather than =. Huh... This fixes the dreaded problem
5272 wherein builtin_type_int becomes TYPE_CODE_FLT.
5273
5274 * core.c (info_files): Show the inferior pid.
5275
5276 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
5277 already knows how to look in the source directory.
5278
5279 * Remove psymtab hair from many places. Remove duplicated code
5280 for searching symbol tables. Hide psymtabs from most places.
5281 Make it fast to get from a psymtab to its symtab.
5282
5283 blockframe.c (blockvector_for_pc): Remove psymtab hair.
5284 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5285 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5286 dbxread.c: export psymtab_to_symtab, make it work if called N times.
5287 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
5288 new symtab completely. New psymtabs get symtab pointer
5289 initialized to zero. Remove MI warning printf.
5290 symtab.h: Comments. Add psymtab to symtab pointer.
5291 (PSYMTAB_TO_SYMTAB): New macro.
5292 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
5293 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
5294 compilation fields.
5295 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
5296 verbose is not set.
5297 (print_frame_info): Avoid special-casing symbols that have not yet
5298 been read in.
5299
5300 * source.c (open_source_file): Quick path if we have already
5301 located the source file by its full name.
5302
5303 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
5304 find_pc_psymtab. When a name is found in the misc function
5305 vector, search the symbol table for its mangled name, not the
5306 name that the user typed.
5307
5308 * bfd.h: Fix missing comment terminators, make #endifs match.
5309
5310 * valarith.c (value_less): Handle unsigned int comparisons.
5311 Add FIXME about pointer compares, which assume host and target
5312 pointers are the same.
5313
5314 * command.c (do_nothing_command): lint
5315 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
5316 fix comments on debug symbol format for visibility. Actually set
5317 visibility of symbols.
5318 main.c (echo_command): lint; use <readline/history.h>.
5319 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
5320 obstack.h (_obstack_blank): Rearrange pointer math to avoid
5321 pointing past end of allocated memory; saber complains.
5322 obstack.h: Declare the external functions that we use.
5323 valarith.h: use <string.h>
5324 solib.c (solib_add): lint.
5325
5326 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
5327
5328 * main.c (initialize_main): Default info_verbose to off, now that
5329 symbol reading is fast.
5330 (quit_command): Avoid clobbering exec_bfd while quitting.
5331
5332 * Initial BFD (binary file diddling library) merger:
5333 coffread.c: Change AOUTHDR to struct exe_hdr.
5334 dbxread.c: ditto.
5335 core.c: initialize initialized data at compile time.
5336 (core_file_command): Move from coredep.c, convert to bfd.
5337 (xfer_core_file): Convert to bfd.
5338 exec.c (exec_file_command): use bfd routines.
5339 gdbcore.h: BFD.
5340 mips-tdep.c: Remove exec_file_command and friends.
5341 source.c: bfd.
5342
5343 * coredep.c: (fetch_core_registers) Convert core_file_command to
5344 fetch_core_registers.
5345 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
5346
5347 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
5348 (my_bfd_read): More bogosity, which I don't think we call.
5349 (program_name): Remove this atrocity asap!
5350
5351 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
5352
5353 * From Per Bothner:
5354 values.c: allocate_repeat_value was not clearing the
5355 optimized_out field.
5356 (value_static_field): minor stylistic fix (wrong macro was used).
5357 valops.c (value_struct_elt_for_address): didn't work for C++
5358 static fields.
5359
5360 * signame.c (_initialize_signame): Initialize signal names once.
5361
5362 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
5363 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
5364 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
5365
5366 * remote-eb.c: Support user-settable baud rates on the serial port.
5367
5368 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
5369
5370 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
5371
5372 * tconfig/sun3os4: Remove warning about native assembler,
5373 since it also occurs in the xconfig file.
5374
5375 * findvar.c (registers): Allocate some slop after `registers'
5376 to prevent stray accesses from trashing the next variable.
5377
5378 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
5379 on the sun-3, by changing the #ifdef from `sun3' (which is not
5380 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
5381 vars, which happened to follow `registers' in the executable.
5382
5383 * readline/history.c (history_search): Heed gcc-2's advice
5384 and parenthesize && inside ||).
5385
5386 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
5387 tm-29k.c: Insert FSF copyright headers.
5388
5389 * remote-eb.c: Better comments.
5390
5391 * Makefile.dist: Update to 3.91.6.
5392 * TODO: note PREPARE_TO_STORE problem.
5393
5394 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
5395
5396 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
5397
5398 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
5399
5400 * infrun.c (wait_for_inferior, at end): Don't set up
5401 prev_* if the inferior no longer exists.
5402
5403 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
5404 CANNOT_EXECUTE_STACK.
5405 valops.c (call_function): Use it.
5406
5407 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
5408
5409 * inferior.h (PC_IN_CALL_DUMMY): New macro.
5410 infrun.c (wait_for_inferior, 2 places): Use it.
5411
5412 * values.c (value_being_returned): Only use
5413 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
5414
5415 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
5416 right thing for remote-eb.c.
5417
5418 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
5419 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
5420
5421 * blockframe.c: Put get_frame_saved_regs inside #if !defined
5422 (FRAME_FIND_SAVED_REGS).
5423
5424 * findvar.c ({fetch,store}_registers): Check for
5425 REMOTE_{FETCH_STORE}_REGISTER macro.
5426
5427 * findvar.c (get_saved_register): Add argument lval and
5428 change meaning of argument addr.
5429 findvar.c: Change calls to get_saved_register to reflect
5430 new calling convention.
5431 valops.c (value_assign): Use get_saved_register instead of
5432 find_saved_register.
5433
5434 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5435
5436 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
5437 an (uninitialized) pointer to one. Use "&" when passing it
5438 to fread.
5439
5440 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5441
5442 * coffread.c (getfilename): Use DGUX x_offset and x_name if
5443 defined.
5444
5445 * coffread.c (symbol_file_command): Put semicolon after
5446 "int from_tty".
5447 Put safe_to_init_tdesc_context in #if defined (TDESC).
5448 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
5449 coffread.c: #include <sys/stat.h>.
5450 (read_coff_symtab): Typo: in_source_files -> in_source_file.
5451 Add missing ')' in check for "lc%" and friends. Remove
5452 extraneous '}'.
5453 Declare read_one_sym() at top of file.
5454 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
5455 MC68WRMAGIC can have the same value without causing a duplicate
5456 case.
5457
5458 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
5459
5460 * Allow a Makefile to be built without building the
5461 tm and xm file links that screw up builds in subdirectories.
5462 This is done with `config.gdb none', then you can do things
5463 like `make gdb.tar.Z'.
5464 * tconfig/none: Config file for no target system
5465 * xconfig/none: Config file for no host system
5466 * config.gdb: If no TM or XM files are called out by the
5467 host or target file, don't make links for them.
5468
5469 * cplus-dem.c: Add documentation.
5470
5471 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
5472 simple error, so the user's gdb doesn't crash due to some object
5473 file problem (e.g. somebody is rebuilding the file out from under
5474 gdb).
5475
5476 * printcmd.c (print_address_symbolic): demangle the symbol.
5477
5478 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
5479 Motorola copyrights in it. Make "make gdb.tar.Z" work.
5480 (alldeps.mak): sort and uniq all results from this; duplicates
5481 hose gdb.tar.Z link building. Remove RCS files from
5482 tconfig and xconfig. Add config files for sun386. Add
5483 a few odd files to OTHERS and HFILES.
5484
5485 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
5486
5487 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
5488 Roll version number to 3.91.5. Make lint work in bindir.
5489
5490 * README: Document cross-debugging and new file structure.
5491
5492 * blockframe.c: Lint. Include "value.h" to declare read_register.
5493 (find_pc_partial_function): remove duplicate line.
5494
5495 * command.h: Lint. Declare error_no_arg and dont_repeat.
5496
5497 * tm-news.h: Remove inadvertently duplicated stuff.
5498
5499 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
5500 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
5501
5502 * config.gdb: Allow `config.gdb host target' form. Clean
5503 up previous change that printed bogus messages when you just said
5504 `config.gdb'.
5505
5506 * core.c: #include "command.h" for lint.
5507 * dbxread.c: lint
5508 * eval.c: lint
5509 * main.c: Remove some casts of enums. Lint.
5510 * source.c: lint
5511 * symtab.c: lint
5512 * symtab.h: lint
5513 * expread.y: lint
5514 * valarith.c: lint
5515
5516 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
5517
5518 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
5519 read it from memory. This will allow us to save ptrace calls
5520 eventually. Changed caller single_step too.
5521
5522 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
5523 that we aren't going to use, saving many ptrace calls, especially
5524 when watchpointing or single stepping. Use some #define's for
5525 constants.
5526 (store_inferior_registers): Ditto.
5527 (core_file_command): Use some #define's for constants.
5528
5529 * tm-sparc.h: Add #define's for some register numbers, so we
5530 can eliminate the use of random constants in sparc-xdep.c.
5531
5532 * stack.c (frame_command, print_frame_info, up_command,
5533 down_command) Remove frame_changed, since it
5534 causes a bug and doesn't seem to do anything useful. In some
5535 places it was used as a flag, in others as a stack level (?).
5536
5537 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
5538 default is to use the portable (vprintf) version rather than the
5539 kludge version.
5540 * xm-news.h (MISSING_VPRINTF): Add.
5541
5542 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
5543
5544 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
5545
5546 * Remove stuff that forces -Bstatic linking of gdb, and warnings
5547 about linking debugged programs -Bstatic in the sun?os4 config
5548 files in tconfig and xconfig subdirectories.
5549
5550 * main.c (main): Remove unreached exit(0) now that we exit
5551 via quit_command().
5552
5553 * Create TODO file for online bug list. There are too many
5554 "little" bugs to keep track of on paper.
5555
5556 * Change Projects file to refer to bug-gdb@cygnus.com
5557 rather than kingdon@ai.
5558
5559 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
5560
5561 * Makefile.dist (VERSION): 3.91.4 now.
5562
5563 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
5564 (condense_misc_bunches): Add sanity check that misc_count is
5565 the same as the number of symbols in the bunch.
5566
5567 * coffread.c: rename init_misc_bunches. Pass an argument
5568 to condense_misc_bunches (a zero).
5569
5570 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
5571 every time we are called; don't rely on our caller to do it.
5572 (add_file): Remove call to init_misc_bunches.
5573
5574 * mipsread.c: Only warn, don't error, if unknown symbol types.
5575 This keeps an old gdb from falling on its face if it sees newly
5576 extended symbol info. Rename init_misc_bunches.
5577
5578 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
5579
5580 * Merge in changes from Per Bothner for DECstations and other
5581 MIPS stuff. The rest is Bothner speaking:
5582
5583 The next message is a merger of Alessando Forin's mips port with
5584 mine. I've tried to use my good if biased judgment to get
5585 the best of both. It *does* need testing.
5586
5587 Some of the changes are general, *not* mips-specific.
5588
5589 param.h:
5590 Didn't believe in little-endian bit order.
5591 There are still inconsistencies about whether flags
5592 like BITS_BIG_ENDIAN are integer (#if ...) or
5593 boolean (#ifdef ...). I tried to paper over them.
5594
5595 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
5596 Moved some misc_function code that was common to
5597 {dbx,coff,mips}read.c to symtab.c.
5598 In the process, I think I cleaned things up a bit.
5599 At the same time, moved obsavestring and obconcat to symtab.c.
5600
5601 dbxread.c:
5602 Removed obsolete condense_addl_misc_bunches (use
5603 condense_misc_bunches(1) instead).
5604
5605 exec.c:
5606 Needed to include <sys/dir>, at least on DECstations.
5607
5608 valops.c, mips-tdep.c, tm-mips.h:
5609 Added PUSH_ARGUMENTS macro to support funny argument-pushing
5610 conventions (when STACK_ALIGN is insufficient).
5611 Needed on mips, where doubles need 8-byte alignment,
5612 but ints only need 4.
5613
5614 mips-opcode.h:
5615 Removed cruft that was not being used.
5616 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
5617
5618 mips-pinsn.c:
5619 Print $ before register-names (I think that makes things a little
5620 more consistent).
5621 Never print two instructions, even if one delays.
5622 Removed hex-disassemble set_cmd. (This is not mips-specific,
5623 so I think the argument is whether it is generally worthwhile or not.
5624 I'm inclined to think not, given how easy it is to
5625 convert between radixes in gdb.)
5626
5627 mipsread.c:
5628 This is basically Alessando's code.
5629 It doesn't use obstacks; I changed it to use obstacks
5630 in a few minor places where using malloc causes a
5631 memory leak. (Probably, more places could/should be changed.)
5632 I added record_misc_function where it was missing.
5633 In symbol_file_command and add_file_command, I tried
5634 to make the code consistent with more recent versions.
5635 Minor sylistic changes in parse_procedure.
5636 Make a .gdbinfo. psuedo-symbol point back to the real
5637 procedure symbol (using the isym field).
5638
5639 mips-tdep.c:
5640 This is basically from my port, but with a lot of details
5641 and a number of routines merged in from Alessando's version.
5642 I basically used my code "raw" backtrace (use heuristics
5643 from the actual code, rather than symbol table info) - though
5644 the idea is Alessandro's. I feel my code is a little cleaner
5645 here, particularly in being a little more flexible, such as being
5646 able to handle gcc-produced code (which it now can).
5647 It also doesn't do frame caching (which is not useful
5648 more recent gdb versions).
5649 I also used my code for push_/pop_dummy, more or less.
5650 I tried to incorporate AF's code for testing sigtramp
5651 while backtracing; I probably got it wrong.
5652 Added mips_print_register, which tries to scrunch as much
5653 information as possible on a screen...
5654 Removed the skip-prologue set_cmd. As with hex-disassemble (see
5655 under mips-pinsn.c), I don't see anything mips-specific here,
5656 and I don't see it being all that useful anyway.
5657
5658 tm-mips.h:
5659 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
5660 Use more register names (rather than hard-cases numbers).
5661
5662 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
5663
5664 * Hack up 3.90.11 changes:
5665
5666 * Makefile.dist (depend): parameterize $(GCC).
5667 Add solib.c and solib.o.
5668 (readline): Fix vpath for both absolute or relative SRCDIR.
5669
5670 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
5671 Also, let the part I didn't understand at least compile so
5672 I can test the rest. FIXME.
5673
5674 * dbxread.c: Fix thinko using strcmp.
5675 (init_psymbol_list): declare static.
5676 (partial_symbol_file_open): Comment cleanups better, avoid
5677 cleaning up the string table since the caller will do that.
5678 Move the stat for mod time into symbol_file_command, temporarily.
5679 (There should be a mod time for each symbol file, eventually,
5680 to control its rereading. FIXME.)
5681
5682 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
5683 SunOS, which gives error for shared libs otherwise. (From
5684 Schaefer, probably FIXME needs work for portability.)
5685
5686 * solib.c: Move #include "param.h" to work.
5687 Lowercase all the Uppercase Letters In the Messages.
5688 (find_solib): Clean up inferior_so_name for debug printouts.
5689 Allow no argument, to mean all shared libraries.
5690
5691 * symmisc.c: include param.h to get CLEAR_SOLIB.
5692
5693 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
5694
5695 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
5696 to 3.90.11. ChangeLog entries below are from this.
5697
5698 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)

5703
5704 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5705
5706 * Version 3.90.10.
5707
5708 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
5709
5710 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
5711
5712 * sparc-opcode.h Added single-operand version of rett.
5713
5714 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5715
5716 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
5717 Put parens around gcc_p in expansion.
5718
5719 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5720
5721 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
5722
5723 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5724
5725 * Changes for Sun shared libraries:
5726 blockframe.c (find_pc_partial_function): If a non-text symbol
5727 is found, set *address = pc - FUNCTION_START_OFFSET.
5728 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
5729 Disable breakpoints instead of giving an error.
5730 source.c (select_source_symtab): Initialize cs_pst.
5731 symmisc.c: Call CLEAR_SOLIB if defined.
5732 symtab.h: Make text{low,high} CORE_ADDR not int.
5733 (psymtab): New field addr.
5734 solib.c: New file.
5735 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
5736 (record_misc_function): Give correct type for N_DATA symbols.
5737 (condense_misc_bunches): do "misc_function_count = j" regardless
5738 of inclink.
5739 Take code which is shared between symbol_file_command and
5740 add_file_command and put it into partial_symbol_file_{open,read}.
5741 Split add_file_command into add_file_command and add_file.
5742 Make psymtab_to_symtab read in the string table if the file
5743 is not symfile.
5744 Two new parameters to read_dbx_symtab and start_psymtab.
5745 tm-sunos.h: New file.
5746
5747 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5748
5749 * infcmd.c: Change cont_command to continue_command and "cont"
5750 to "continue".
5751
5752 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5753
5754 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
5755
5756 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
5757
5758 * values.c (USE_STRUCT_CONVENTION): Check for structures of
5759 size 1,2,4,8 rather than size < 8.
5760
5761 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
5762 as necessary, not just once.
5763
5764 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
5765
5766 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5767
5768 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
5769
5770 * tm-news.h: Add CALL_DUMMY_*.
5771
5772 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
5773
5774 * config.gdb: In list_host, list_target, use ${i}, not $i.
5775
5776 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5777
5778 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
5779
5780 * sparc-opcode.h: Change all store floating-point state register
5781 instructions to have the right match & lose fields.
5782
5783 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5784
5785 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
5786 VPATH to readline.
5787 config.gdb: If srcdir != ., create readline directory and
5788 copy a makefile into it.
5789
5790 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
5791 consistency with POSIX.
5792
5793 * breakpoint.c (bpstat_stop_status): Disable watchpoint
5794 when we exit its exp_valid_block.
5795
5796 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
5797
5798 * Makefile.dist: Bump version to 3.91.3.
5799
5800 * Clean up handling of breakpoint commands (somewhat).
5801 Prompted by Tiemann bug report "cont 10" doesn't work any more.
5802
5803 inferior.h: Add breakpoint_proceeded to inferior status struct
5804 and globals; save it and restore it.
5805 (clear_breakpoint_commands): Cleanup, remove old #define.
5806
5807 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
5808 (save_inferior_status, restore_inferior_status): handle it also.
5809 (proceed): Remove earlier code that set breakpoint_proceeded.
5810 It is now set only in clear_proceed_status.
5811 (clear_proceed_status): Cleanup, use bpstat_clear rather
5812 than clear_breakpoint_commands. No callers need the stop_bpstat
5813 between clear_proceed_status and proceed.
5814
5815 infcmd.c: Add breakpoint_proceeded definition and comment.
5816 (cont_command, jump_command, signal_command): Move call to
5817 clear_proceed_status right next to call to proceed.
5818
5819 breakpoint.c (bpstat_do_actions): Avoid clobbering our
5820 caller's argument while running down the chain of breakpoints.
5821 Use new variable "breakpoint_proceeded" to determine when
5822 a command that it executes moves the inferior past the
5823 breakpoint.
5824 (bpstat_clear): Handle NULL argument.
5825 (bpstat_clear_actions): Avoid useless call to
5826 breakpoint_auto_delete.
5827 (delete_breakpoint): Clean up bpstat's that are pointing to
5828 the deleted breakpoint from the stop_bpstat chain.
5829 (breakpoint_auto_delete): Simplify.
5830
5831 * Clean up handling of EOF, error on stdin, etc. This was
5832 prompted by a network problem that caused gdb to go into an
5833 infinite loop filling up its malloc'd memory.
5834
5835 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
5836 not clear_breakpoints_commands, which is now gone.
5837 (main): If command_loop returns (e.g. from EOF on stdin), do
5838 a quit_command (looping back to command_loop if quit_command
5839 doesn't really quit).
5840 (command_loop): check result from command_line_input and
5841 exit if it returns NULL, rather than passing the NULL to
5842 execute_command.
5843 (gdb_readline): Free malloc'd result space before returning
5844 NULL for EOF.
5845
5846 * utils.c (query): Handle C-d to mean "yes", just as if the
5847 input was not a terminal. Also avoid infinite loop if EOF
5848 occurs in mid-input-line before newline. This allows
5849 query to be used at EOF on stdin with reasonable results.
5850
5851 * infrun.c (proceed): Set breakpoint_proceeded.
5852
5853 * values.c (value_as_long): Avoid infinite recursion for enums.
5854 (_initialize_values): Fix typo in help msg (kingdon).
5855
5856 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
5857 RL_LIB for linking. This allows -lreadline for linking
5858 and nothing for dependencies, once readline is a real library.
5859
5860 * config.gdb: Jim Kingdon: give useful error message if the
5861 host or target type is not recognized.
5862
5863 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
5864 it just defines it. Dumb, but deal with it.
5865
5866 * Jim Kingdon suggests:
5867 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
5868
5869 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
5870
5871 * Makefile.dist (VERSION): Bump version # to 3.91.2.
5872
5873 * Clean up Bothner's changes.
5874
5875 * blockframe.c (clear_pc_function_cache): New function.
5876 * blockframe.c: remake cache_pc_function_* static.
5877 * dbxread.c (symbol_file_command): remove references to
5878 cache_pc_function_* variables.
5879 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
5880 * printcmd.c: Avoid kludging a global variable (addressprint)
5881 to avoid printing the address of a string twice. Instead,
5882 pass the format letter 's' down low enough that it can be seen
5883 to avoid this problem.
5884 (print_formatted): Pass format arg to value_print.
5885 (restore_addressprint): Remove function.
5886 (do_examine): Avoid hacking addressprint, cleanups and such.
5887 (print_frame_args): Add a comment to a Bothner change.
5888 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
5889 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
5890 to wipe out the values cached in blockframe.c.
5891 * symtab.c (find_method): Add comment saying how big you must
5892 allocate to be "big enough". Per being terse again.
5893 * valprint.c (val_print): Handle format letter "s" to print
5894 strings without addresses. Add comment to vtbl printing code
5895 which casts with wild abandon. Rearrange reference-printing
5896 code so it prints:
5897 @0xaddr: value (print w/addressprint)
5898 value (print w/~addressprint)
5899 @0xaddr (parameter lists w/addressprint)
5900 or nothing (parameter lists w/o addressprint)
5901
5902 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
5903
5904 * Merge more changes from Per Bothner:
5905
5906 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
5907 annoying) that I tried to improve it. Here are my suggestions.
5908
5909 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
5910
5911 findvar.c:
5912 Do automatic de-reference when taking the address of a reference.
5913 printcmd.c:
5914 Don't deref_ref when printing parameter lists.
5915 valops.c:
5916 More attempts at treating refernences properly.
5917 valprint.c:
5918 In val_print, if deref_ref==0, don't print dangling " = ".
5919 value.h:
5920 Add COERCE_REF macro, which de-references an REF.
5921
5922 * Merge changes from Per Bothner:
5923
5924 * Fixed (Sony news)-specific configuration problems.
5925 * Fixed other problems with using vanilla pcc and libc (enum problems;
5926 assumption that vsprintf exists).
5927 * Some major speed-ups (finc_pc_partial_function now caches a match;
5928 parsing avoids duplicate symbol_lookup calls).
5929 * Changed handling of baseclasses (no longer use baseclasses field
5930 of struct type, use the first n_baseclasses fields instead).
5931 * Various minor changes/fixes, most C++-related.
5932
5933 blockframe.c:
5934 Cache the most previous match from find_pc_partial_function.
5935 (Save both low and high ends of matching function's pc range.)
5936 This speeds up the loop of infrun.c:wait_for_inferior quite
5937 a bit, and makes step/next commands much zippier.
5938 command.c:
5939 Added an enum->int cast (otherwise, some compilers barf).
5940 dbxread.c:
5941 No longer set baseclass offset to 0, since multiple
5942 inheritance now mostly works.
5943 Added a number of casts, to shut up compiler warnings
5944 (after stabs where made enums, not ints).
5945 When discarding a symbol table (in symbol_file_command),
5946 must clear the cache introduced in blockframe.c.
5947 Don't convert $vtbl_ptr_type to vtbl any more.
5948 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
5949 Mask off sign bit emitted by g++ for virtual table offset.
5950 Set voffset to -1 (not 1) for static member functions.
5951 expread.y:
5952 Changed parsing/lexing of names to avoid doing symbol lookup twice
5953 (once when lexing to determine symbol class, once for real).
5954 Now only call symbol_lookup once. Fields of 'this' win especially big.
5955 printcmd.c:
5956 Subpress printing addr twice in the case of 'x/s addr'.
5957 symtab.c:
5958 lookup_basetype_type is no longer used.
5959 Add find_methods as recursive helper function to decode_line_1.
5960 This allows multiple inheritance to work.
5961 Also, once one or more matches has been found, do not look in
5962 base-classes. (Baseclass methods would be overridden, anyway.)
5963 symtab.h:
5964 Removed baseclasses array in struct type.
5965 Instead of using baseclasses[i], use fields[i-1].
5966 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
5967 Changed sign convention of voffset (previous was inconsistent).
5968 tm-news.h:
5969 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
5970 utils.c:
5971 Used to assume existence of vsprintf. Re-written to not need it
5972 if HAVE_VPRINTF is undefined.
5973 valops.c:
5974 typecmp was too pessimistic. Made it less so.
5975 valprint.c:
5976 Don't print space after address.
5977 If vtable points to a misc symbol (with 0 offset), print it,
5978 since that indicates the actual class of the object.
5979 Changed ype_print_derivation_info to use new inheritance
5980 scheme (without baseclasses vector).
5981 values.c:
5982 In value_primitive_field, fixed some bugs left over from previous set of fixes.
5983 Also, changes needed because TYPE_BASECLASSES were removed.
5984 xm-news.h:
5985 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
5986
5987 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
5988
5989 * source.c:
5990 If there is no path set, and the symbols don't indicate what directory
5991 a file was compiled in, look in the current directory. But either
5992 a path or a known compilation directory will prevent this.
5993
5994 * dbxread.c:
5995 Three independent bug fixes:
5996 * Remove the #if 0 block that breaks some stuff.
5997 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
5998 adapt gdb to either SunOS 4.0.* or 4.1.
5999 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
6000
6001 * symtab.c:
6002 Instantiate the class T when looking for methods in it. (Tiemann@sun)
6003
6004 * valprint.c:
6005 (type_print) Demangle the name being printed.
6006 (type_print_base) Handle botched demangling without coredump (tiemann).
6007
6008 * values.c:
6009 (check_stub_method): Document routine.
6010 (tiemann) fix bug for no-arg functions
6011 Avoid clobbering beyond end of malloc'd storage.
6012 Terminate the argument list properly.
6013
6014 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
6015
6016 * Changes merged by John Gilmore:
6017
6018 breakpoint.c:
6019 In breakpoint_1, use new print_address_symbolic instead
6020 of find_pc_partial_function. (This forces use of assembler-level
6021 addresses, and avoids misleading non-mangled source-level names.)
6022 cplus-dem.c:
6023 Generalize ansi argument such that -1 means skip arglist totally.
6024 Removed global variable print_ansi_qualifiers (which made
6025 code non-reentrant), in favor of extra explicit arguments
6026 to internal routines.
6027 printcmd.c:
6028 Add new helper function print_address_symbolic.
6029 Use find_pc_misc_function instead of find_pc_partial_function
6030 (since we want assembler-level symbols here).
6031 stack.c:
6032 Print unknown function as just "f (...)", not "f (...) (...)".
6033 Use new fputs_demangled explicitly.
6034 symtab.c:
6035 Fixed a typing violation (problem: value.h cannot be imported
6036 without renaming many variable in this file).
6037 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
6038 decode_line_1: Moved forward some never-reached code.
6039 Made decode_line_2 skip function prologues correctly.
6040 utils.c:
6041 fputs_filtered should not demangle by default.
6042 Add new fputs_demangled to demangle on demand..
6043 valops.c:
6044 Change value_struct_elt to use value_primitive_field (using recursive
6045 utility function search_struct_field). This allows foo.bar to work
6046 for multiple inheritance (so far only for data fields).
6047 Change check_field in the same way (recursive helper function
6048 to support multiple inheritance).
6049 (Note: there are more of these problems that I haven't fixed.
6050 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
6051 value_of_this: 'this' symbol name is now just "this", note "$this".
6052 valprint.c:
6053 Don't print static members.
6054 Avoid printing "members of <type>" if there are none.
6055 Simplified type_print_derivation_info by merging duplicate code.
6056 Remove useless blank lines in type_print_base (ptype command).
6057 value.h:
6058 Added declaration of new routine value_primitive_field.
6059 values.c:
6060 Added value_primitive_field which is generalized version of
6061 value_field that can handle multiple inheritance (non-zero offsets etc).
6062 Re-implemented value_field to call value_primitive_field.
6063
6064 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
6065
6066 * infcmd.c -- insert else to avoid 'delete env' coredump when you
6067 delete the whole environment. Karl Berry reported the bug.
6068 * source.c - fix openp to avoid //'s in filenames, which
6069 trigger an Emacs bug causing it to not be able to find files
6070 when running gdb in a window.
6071 * dbxread.c - zap the #if 0 that botches the add-file code.
6072 It seems to work a lot better without all the code commented out.
6073
6074 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
6075
6076 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
6077 into gdb-3.90.9.
6078
6079 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
6080
6081 * Makefile - added a ${CFLAGS} to a couple of entries,
6082 added remote-sa.sparc.c
6083 * added remote.sa-sparc.c, a modification of remote.c
