1 Mon Nov 4 10:49:33 1991 Per Bothner (bothner at cygnus.com)
3 * infrun.c: Fixed typo in comment.
4 * utils.c: All the v*fprintf emulation is now in libiberty,
5 so we can get rid of some junk.
6 * xm-sun3os4.h, xm-sun4os4.h, xconfig/decstation, xconfig/i386sco,
7 xconfig/sun3os4, xconfig/sun4os4: Don`t need HAVE_STRSTR any more.
8 * m68k-pinsn.c (print_insn_arg): Support BB/BW/BL
9 type operands, as used by branch instructions.
10 * gmalloc.c: Fix prototype of memcpy.
11 * elfread.c: Comment out register_addr, since it conflicts
12 with the one in coredep.c.
13 * buildsym.h: Remove extern declarations of two functions
14 that are really static in buildsym.c.
15 * tm-mips.h: Add symbolic names for more registers.
16 * mips-xdep.c (store_inferior_registers): Use new register names.
17 * xm-mips.h: Simplify REGISTER_U_ADDR, since it is now
18 only used for core files, not ptrace. Therefore,
19 the KERNEL_U_ADDR hack is no longer needed.
20 The mapping to ptrace number is now in in mips-xdep.c.
21 * mips-xdep.c: Define REGISTER_PTRACE_ADDR (using the
22 mapping from the old REGISTER_U_ADDR), and use it
23 in {fetch,store}_inferior_registers.
24 * mipsread.c: Rename #include ecoff.h to new name coff-mips.h.
25 * mips-tdep.c (mips_push_dummy_frame, mips_pop_frame):
26 Save/restore FP regs correctly (?).
27 * dbxread.c: Remove duplicate define_symbol and type_synonym_name
28 (these had been previously moved to buildsym.c).
29 Hence, define_symbol becomes extern instead of static.
30 * buildsym.c (read_struct_type): Comment out bogus handling
31 of C++ operator methods. Minor hacking of reading of class
32 contexts. Make define_symbol non-static, so dbxread.c can call it.
34 Fri Nov 1 11:05:47 1991 John Gilmore (gnu at cygnus.com)
36 * mipsread.c (read_mips_symtab, read_the_mips_symtab): Use real
37 filename with error messages.
38 * stack.c (frame_select_command): Rename to select_frame_command
39 to avoid "fr" and "fra" having nonunique completions.
40 * symfile.c (sort_symtab_syms): Ignore sort of zero symtab *.
41 (symfile_init): Print file format name when unable to handle it.
42 (free_named_symtabs): Use BLOCKVECTOR rather than obsolete BLOCKLIST.
43 * symmisc.c (free_symtab): Only free linetable if nonzero.
44 * symtab.h: Remove obsolete BLOCKLIST macros.
46 Thu Oct 31 18:12:43 1991 Stu Grossman (grossman at cygnus.com)
48 * infrun.c (wait_for_inferior): another stepi/nexti fix. Ensure
49 that stop_step is 1 at bottom of main loop. I don't know why this
50 needs to be done, but it helps me sleep better at night.
52 Sun Oct 27 18:18:39 1991 Stu Grossman (grossman at cygnus.com)
54 * main.c (initialize_history): Read history after reading all
57 Sun Oct 27 14:09:25 1991 John Gilmore (gnu at cygnus.com)
59 * buildsym.c: Break out initial malloc sizes.
60 (record_line): Record directly in a subfile. Alloc on demand.
61 (compare_line_numbers): Add from xcoffread.c.
62 (end_symtab): New params say whether to sort pendings and
63 linetable. Patch block stabs if defined. Shrink linetable before
64 allocating the symtab.
65 * buildsym.h: Delete line_vector* and prev_line_number. Add
66 global_stabs and file_stabs for xcoffread.
67 * dbxread.c (start_subfile): Move to buildsym. Change above calls.
68 * symtab.h: LINETABLE(symtab) can now be null. Zap LINELIST.
69 * symmisc.c, symtab.c: Cope with null LINETABLEs.
71 * blockframe.c: Pass fromleaf to INIT_EXTRA_FRAME_INFO.
72 * tm-29k.h, tm-88k.h, tm-i960.h, tm-irix3.h, tm-mips.h, tm-pyr.h,
73 tm-sparc.h: Accept fromleaf parameter.
74 * c-exp.y (yyerror): Pass error message if given.
75 * configure.in: Add rs6000 host and target.
76 * inflow.c (new_tty): O_NOCTTY kludge for RS/6000.
77 * symfile.h (entry_point): Add.
79 Sat Oct 26 00:16:32 1991 John Gilmore (gnu at cygus.com)
81 * buildsym.c: New file. Breaks out symbol-table-building routines
82 from dbxread.c, so they can be shared with xcoffread.c.
83 * buildsym.h: New file. Declarations for buildsym.c users.
84 * dbxread.c: Remove large chunks into buildsym.c.
85 * Makefile.in: Add buildsym.c and buildsym.h.
87 * symfile.c (syms_from_bfd): New routine.
88 (add_symbol_file): Call it to do the real work.
89 (syms_from_bfd): Initialize entry_point before calling symfile_init.
90 * symtab.h, symfile.c, coffread.c, mipsread.c, dwarfread.c:
91 Avoid declaring or setting entry_point (symfile.h & symfile.c cope).
93 Fri Oct 25 18:59:32 1991 Per Bothner (bothner at cygnus.com)
95 Various fixes to improve g++ debugging.
96 * symtab.h: Add is_const and is_volatile flags for each method.
97 These are bit fields - take their space from voffset,
98 which shrinks to 30 bits. Since voffset is now a bitfield,
99 make it unsigned for portability. This changes its interpretation
100 slightly: Static methods now have voffset 1 instead of -1,
101 and virtual offsets start at 2, not 1.
102 * symtab.c: Renamed gdb_mangle_typename to gdb_mangle_name,
103 since it now returns an entire magled method name, not just
104 the type part. This avoids some duplication.
105 It also allows us to correctly mangle const and volatile
106 methods (using the new is_const and is_volatile bit fields
108 * valprint.c (type_print_base), values.c (check_stub_method):
109 Simplify by using new gdb_mangle_name.
110 * values.c (value_headof): Fix to correctly handle single
111 inheritance (actually two fixes, either of which suffices).
112 * dbxread.c (read_struct_type): Handle const and volatile
114 * dbxread.c (read_struct_type): Yet one more place where
115 we must handle '\\' continuations.
116 * valprint.c (vtbl_ptr_name): Add final '\0'.
118 Fri Oct 25 16:06:38 1991 Stu Grossman (grossman at cygnus.com)
120 * tm-sparc.h, tm-68k.h (EXTRACT_RETURN_VALUE): fix output of
121 short return values for sparc and 68k. Patch from Paul Eggert.
123 * coffread.c, coredep.c, i386-xdep.c: install patches for
124 SysV/386 3.2 from Mauro DePalma.
126 Fri Oct 25 02:02:13 1991 John Gilmore (gnu at cygnus.com)
128 * core.c (core_file_info), exec.c (exec_file_info): Print file
129 type. Use printf_filtered.
131 * valops.c (value_fetch_lazy): Avoid 0-length fetches.
133 Thu Oct 24 23:06:40 1991 Fred Fish (fnf at cygnus.com)
135 * dwarfread.c: Add casts to remove compiler warnings.
137 * tm-3b1.h, tm-68k.h, tm-altos.h, tm-amix.h, tm-hp300bsd.h,
138 tm-hp300hpux.h, tm-isi.h, tm-news.h, tm-pn.h, tm-sun2.h,
139 tm-sun3.h: Remove locally duplicated code for calling functions
140 in the inferior. The only differences were in the specific trap
141 vectors used and whether or not an fpu was present. These are
142 now handled by appropriate definitions of BPT_VECTOR and
143 HAVE_68881 respectively. Other minor obvious cleanups.
145 * valops.c: Correct a minor misspelling.
147 * utils.c: Remove local BSD/USG hacks that are now in libiberty.
149 * dwarfread.c: Remove prototype for dwarfwarn. Does not work
152 Thu Oct 24 09:33:44 1991 John Gilmore (gnu at cygnus.com)
154 * stack.c (frame_command): Always print. Use new
155 frame_select_command to select a frame without printing.
157 * dwarfread.c: Use <varargs.h>, since <stdarg.h> is not portable.
159 Thu Oct 24 01:32:51 1991 Fred Fish (fnf at cygnus.com)
161 * dwarfread.c: New file for DWARF debugging format support.
163 * elfread.c: New file for ELF object file format support.
165 * procfs.c: New file for SVR4 /proc (process file system) support.
167 * tm-amix.h, xm-amix.h, tconfig/amix, xconfig/amix: New files for
170 * xm-svr4.h, tm-svr4.h: New files for SVR4 support.
172 * xm-m68k.h: New file for host machines with m68k cpu.
174 * Makefile.in: Add elfread.c and dwarfread.c to SFILES_MAINDIR.
175 Add elfread.o and dwarfread.o to OBS.
177 * symfile.h: Add "elf" to list of supported formats in comment.
179 * c-exp.y, defs.h, symtab.h, valprint.c: Add three new builtin
180 types to gdb, builtin_type_long_double, builtin_type_complex, and
181 builtin_type_double_complex. Add and use new TARGET_SHORT_BIT,
182 TARGET_INT_BIT, TARGET_LONG_BIT, TARGET_FLOAT_BIT,
183 TARGET_DOUBLE_BIT, TARGET_LONG_DOUBLE_BIT, TARGET_COMPLEX_BIT, and
184 TARGET_DOUBLE_COMPLEX_BIT, as the sizes in bits of the indicated
185 types on the target machine (ala the existing TARGET_LONG_LONG_BIT).
187 * infrun.c: When using SVR4 /proc interface instead of ptrace(),
188 call proc_set_exec_trap() to setup child to stop at first instruction.
190 * inftarg.c: When using SVR4 /proc interface, call proc_wait()
193 * m68k-tdep.c: Add new routines supply_gregset(), fill_gregset(),
194 supply_fpregset(), and fill_fpregset(), which are machine
195 dependent support routines for SVR4 /proc interface.
197 * utils.c: Add warning_setup() and warning(). Warning() behaves
198 the same as error() except that it returns normally rather than
199 jumping back to command level. Modules that don't want to call
200 warning() for some reason, but want to produce their own warnings,
201 can call warning_setup() to ensure compatibility with the way
202 warning() and error() deal with the terminal.
204 * symtab.c: Make internal errors produce more useful messages.
206 * tm-68k.h: Move code that is duplicated in almost every single
207 m68k based machine's configuration files to this common file.
208 Duplications in the configuration files still need to be removed
211 * infrun.c (child_create_inferior): System V versions must call
212 setpgrp() with no arguments, to comply with prototyping typically
215 * munch: Add support for SVR4 style nm output.
217 * dbxread.c, mipsread.c symmisc.c, symtab.c: Remove the object
218 file specific fields from the partial symbol table structure and
219 replace them with a pointer to private data for each different
220 flavor of object file reader to initialize appropriately.
222 Wed Oct 23 09:38:20 1991 John Gilmore (gnu at cygnus.com)
224 * xconfig/sun[34]os4: Add note about strstr botch on sunos4.0.3c
227 * mipsread.c (fixup_undef_type): New function. If a struct /
228 union / enum is defined in a header file but nowhere else used,
229 (by typedefing, pointer referencing or declaration) the mipsread code
230 builds the complete tree for the structure but leaves its code as
231 TYPE_CODE_UNDEF as it doesn't know what kind of aggregate it is.
232 Guess its type based on the details of the members.
234 Tue Oct 22 18:04:32 1991 Stu Grossman (grossman at cygnus.com)
236 * infrun.c (wait_for_inferior): Check return value from
239 Mon Oct 21 17:47:03 1991 Stu Grossman (grossman at cygnus.com)
241 * infrun.c (wait_for_inferior): fix stepi/nexti that was broken
242 by my last edit to this routine.
244 Mon Oct 21 14:27:43 1991 John Gilmore (gnu at cygnus.com)
246 * tm-sun3.h (FIX_CALL_DUMMY): problem with cross debugging.
247 FIX_CALL_DUMMY does unaligned accesses and/or forgets to byte swap
248 the values before putting them into the dummy code. (From Peter
251 Mon Oct 21 10:04:39 1991 Steve Chamberlain (steve at rtl.cygnus.com)
253 * configure.in: added ebmon target.
255 Wed Oct 16 22:49:58 1991 John Gilmore (gnu at cygnus.com)
259 * Makefile.in: Roll VERSION to 4.2.
260 * README, TODO, WHATS.NEW: Update.
262 * core.c (core_open): Improve error message for bad file.
263 Pass .reg virtual memory address to fetch_core_registers to help
264 it find the registers in the core-file header.
265 * coredep.c (fetch_core_registers): Take new argument, use it,
266 and pass it to register_addr to locate the block of registers.
267 * xm-mips.h: Update KERNEL_U_ADDR for new scheme. Cleanup a bit.
269 * dbxread.c (read_dbx_symtab, process_one_symbol): Handle
270 Sequent N_FN_SEQ like everybody else's N_FN.
272 * main.c: Circumvent SCO cc bug with #if !!defined(USG).
273 * tm-i386v.h: #endif guck.
274 * xconfig/i386*: Remove -Dgetpagesize()=4096 kludge.
275 * xconfig/i386sco: Add HAVE_STRSTR to avoid ANSI bdeath.
276 * xconfig/tahoe: Add REGEX, which seems to be missing.
278 * coredep.c: Add <sys/types.h> for SCOnix.
279 * dbxread.c (read_dbx_symntab): Avoid coredump on malformed file.
280 * printcmd.c (print_formatted): Flush output before disassembly.
282 Tue Oct 15 20:12:32 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
284 * doc/refcard.tex (sec "Working Files"): consistent metavars and
285 other improvements, due to comments by François Pinard
286 (pinard@iro.umontreal.ca)
288 * doc/gdb.texinfo (appendix "Installing GDB"): changes in
289 configure, and improvenets related to Pinard's refcard comments
291 Tue Oct 15 08:45:12 1991 John Gilmore (gnu at cygnus.com)
293 Changes from Fred Fish:
294 * tm-68k.h (FPI_REGNUM): Add.
295 * infrun.c (child_create_inferior): flush stdout and stderr
297 * configure.in: Handle amigados, amix hosts and targets.
298 * inflow.c: Handle TIOCGLTC_BROKEN for Amiga.
301 * values.c (show_convenience): Use printf_filtered.
302 * main.c (define_command): Check result of lookup_command for
304 (echo_command): Use printf_filtered, and force output out.
306 * dbxread.c (read_enum_type): Avoid Modula-2 kludge that breaks C
308 * i387-tdep.c (double_to_i387): Fix typo for double_to_ieee_extended.
309 * utils.c (_initialize_utils): If !ISATTY, don't paginate.
310 * configure.in, tconfig/decstation, xconfig/decstation: Rename
311 dec3100 to decstation.
313 Mon Oct 14 13:37:50 1991 Roland H. Pesch (pesch at cygnus.com)
315 * doc/gdb.texinfo: Catch up to changes recorded here in ChangeLog
316 (nodes Continuing and Stepping; Memory; Targets) clarifications
319 Fri Oct 11 23:27:06 1991 John Gilmore (gnu at cygnus.com)
321 * tm-{irix3,mips,nindy960,pn,symmetry,vx960}.h: Move
322 REGISTER_U_ADDR to corresponding xm- file. Sugg. by Peter Schauer.
324 * symmisc.c (print_partial_symtabs): Add printpsyms debug cmd.
326 * m68k-tdep.c (m68k_push_dummy_frame, m68k_pop_frame): Add
327 generic routines for calling inferior functions.
329 * blockframe.c (inside_main_scope, inside_entry_scope): New.
331 * copying.awk: Filter formfeeds out of copying & warrantee.
332 Make them available as `show copying' and `show warrantee' also.
333 * main.c (print_gnu_advertisement): Advt `show' commands.
335 Thu Oct 10 17:25:47 1991 John Gilmore (gnu at cygnus.com)
337 * mach386-xdep.c: Even when cross-compiling, leave in the
338 core-file reading code.
339 * core.c (get_core_registers): Avoid coredump if no .reg section.
341 Wed Oct 9 17:03:34 1991 John Gilmore (gnu at cygnus.com)
343 * mipsread.c, coffread.c: initialise TYPE_VPTR_FIELDNO to -1.
344 This avoids coredumps under `set print object on' in value_headof
345 (called erroneously by value_from_vtable_info) for `p &struct'
346 or `p *struct'. From Peter Schauer.
348 Mon Oct 7 00:06:52 1991 John Gilmore (gnu at cygnus.com)
350 * Makefile.in: Roll version to 4.1.2.
351 * dbxread.c: Use aout64.h, not a.out.gnu.h. Get external symbol entry
352 size from BFD (but, FIXME, we don't yet read external nlists's and
353 convert them to internal nlists's before handling them -- we still
354 assume they have the same size and alignment.) Use SET_NAMESTRING
356 * exec.c (exec_file_command): Move dead coff-encapsulation code
358 * m88k-tdep.c, m88k-xdep.c: Remove encap test and #inc <a.out.h>.
360 Fri Oct 4 22:30:06 1991 John Gilmore (gnu at cygnus.com)
362 * configure.in, tm-i386v.h, xm-i386v.h: Intel 386 Mach host port.
363 * xm-i386mach.h, mach386-xdep.c, xconfig/i386mach: New files.
365 Fri Oct 4 17:04:31 1991 Per Bothner (bothner at cygnus.com)
367 More patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
368 * mips-xdep.c (store_inferior_registers): Don't try to
369 write the (pseudo) FP.
370 * mipsread.c (parse_partial_symbols): Improved algorithm for
371 setting pst->texthigh.
373 Fri Oct 4 16:47:32 1991 Roland H. Pesch (pesch at cygnus.com)
375 * doc/Makefile: make TEXINPUTS include . everywhere
377 Fri Oct 4 00:35:56 1991 John Gilmore (gnu at cygnus.com)
379 * coffread.c, dbxread.c, symfile.c, symmisc.c, symtab.h: Remove
380 vestiges of typevectors, which were for symsegs and are no longer
381 used. (From a question by Eliot Dresselhaus
382 <dresselh@RFT30.nas.nasa.gov>).
384 Thu Oct 3 09:33:26 1991 John Gilmore (gnu at cygnus.com)
386 * dbxread.c, coffread.c: static-ize functions that were
387 gratuitiously external. (From Fred Fish.)
389 * c-exp.y: sym->class to SYMBOL_CLASS (sym).
391 * dbxread.c (dbx_lookup_type): Keep doubling size of typevector
392 until it is large enough.
394 * dbxread.c (read_type): Handle error case slightly better.
395 Make complaint message not C++-specific.
397 Wed Oct 2 17:21:07 1991 Stu Grossman (grossman at cygnus.com)
399 * infrun.c (wait_for_inferior): Fix step/next so that you only
400 stop at the beginning of a new line. This fixes various problems
401 with for loops, nested if-else's and switch statements.
403 Tue Oct 1 06:33:55 1991 John Gilmore (gnu at cygnus.com)
405 * symtab.c (lookup_symtab_1, lookup_symbol): "fatal" errors
406 between symtabs and psymtabs become ordinary error()s.
408 * dbxread.c (read_dbx_symtab): Relocate end_of_text_addr
409 properly, making "end pc" correct in shared lib psymtabs.
410 (From Guy Harris <guy@auspex.com>.)
412 Mon Sep 30 13:15:31 1991 John Gilmore (gnu at cygnus.com)
414 * dbxread.c: Enable, but soften, const_vol_complaint.
415 (read_dbx_symtab): N_STSYM and N_LCSYM define static vars.
416 Ditto Gould N_NBSTS and N_NBLCS. Also, all types in the psymtab
417 should be file-scope, not global.
418 (read_struct_type): Remove ancient multiple-inheritance warning.
419 (read_range_type): Check base type, complain & patch if undefined.
420 * stack.c (frame_info): Demangle the function name in `info stack'.
423 Sat Sep 28 10:02:33 1991 John Gilmore (gnu at cygnus.com)
425 * eval.c (evaluate_subexp_for_address): Don't use
426 TYPE_POINTER_TYPE directly (it might be zero if this type has
427 never had a pointer created before); use lookup_pointer_type.
428 * symtab.c (lookup_method_type): Arguments were swapped in all
429 callers, so fix it here. I'm amazed this worked at all!
431 Fri Sep 27 18:09:31 1991 John Gilmore (gnu at cygnus.com)
433 * c-exp.y, m2-exp.y: Define more yysymbols that happen to be
434 "bss" rather than "data" symbols, but which still conflict.
437 * coffread.c (coff_symfile_read): Use xmalloc, not malloc.
438 * core.c (core_files_info): Shorten output.
439 * exec.c (exec_files_info): Ditto.
440 (build_section_table): Ignore zero-length sections.
441 * language.c, printcmd.c: Lint.
442 * language.h (get_frame_language): Declare.
443 * saber.suppress: update.
444 * stack.c (find_relative_frame): Remove complex code that was
445 #if 0'd, stick with simple code. Lint.
446 * saber.suppress: Update a bit.
447 * symfile.c (add_symbol_file_command): Add "?" to question.
448 * utils.c (parse_escape): Avoid \a due to bdead compilers.
449 * value.h: Declare typedef_print.
451 * valprint.c (val_print, type_print_base): TYPE_CODE_RANGE less
454 * nindy-tdep.c (nindy_frame_chain_valid): Use lookup_misc_func.
455 (Reported by Mark Peek <mark@imagen.com>.)
457 * solib.c (solib_map_sections): Relocate all sections, even
458 though only the text section's size is tracked. Mark ld_text
459 for eventual elimination as we generalize to N sections.
461 * infrun.c (wait_for_inferior): Don't check if the PC is in a
462 call_dummy if we were stopped by a random signal that is being
463 passed to the program. This produced wierd results when calling
464 functions in the inferior and signals (e.g. SIGALRM) were in use.
466 Tue Sep 24 18:05:30 1991 John Gilmore (gnu at cygnus.com)
468 * infrun.c (IN_SIGTRAMP): Not parenthesized properly.
469 Bugfix from Paul Eggert <eggert@twinsun.com>.
470 * tm-ultra3.h (IN_SIGTRAMP): Ditto.
471 * valprint.c (print_floating): Print 9 digits for IEEE floats.
474 Mon Sep 23 15:50:07 1991 John Gilmore (gnu at cygnus.com)
476 * Makefile.in: Roll VERSION to 4.1.1.
477 * source.c (line_info): Peter Schauer fixes a bug I introduced in
480 Fri Sep 20 16:10:52 1991 John Gilmore (gnu at cygnus.com)
484 * Makefile.in (VERSION): Set to 4.1.
485 * language.c (set_language_command): Print useful help message,
486 and restore the language string after giving help.
487 * valprint.c (typedef_print): Print typedef in C or M2.
488 * symtab.c (list_symbols): Use it.
489 * main.c (main): Avoid any output before (gdb) prompt when -q.
490 * language.c (set_language_command): Handle errors by restoring
491 the language string to its current state (fix from A. Beers).
492 * doc/gdbint.texinfo: Roll in information from README. Rearrange
493 "how to install" and "how to print the doc" stuff so it drops
495 * configure.in: Rename rtpc CPU to romp to match config.sub.
496 * README, WHATS.NEW, TODO: Update for gdb-4.1.
498 Fri Sep 20 17:39:14 1991 Roland H. Pesch (pesch at cygnus.com)
500 * doc/gdb.texinfo: Updates from ChangeLog. set/show write,
501 autoloading shared libs, copyright etc on GDB startup, clean up $_
502 and $__ index refs, set/show listsize and related updates to list
503 cmd. New host/target configs.
505 Fri Sep 20 15:46:00 1991 Roland H. Pesch (pesch at cygnus.com)
507 * doc/Makefile: generate aux version-no file doc/gdbVN.m4
508 from main Makefile.in version definition
509 doc/gdb.texinfo: use version recorded in doc/gdbVN.m4 for current
511 Makefile.in (setup-to-dist): generate doc/gdbVN.m4
513 * doc/gdb.texinfo: merge new language-switching and lang-specific
516 Fri Sep 20 15:00:57 1991 Per Bothner (bothner at cygnus.com)
518 * mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
519 compilers (which may lack stddef.h).
521 Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com)
523 * dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and
524 N_WARNING are the same except for the N_EXT bit, so just use their
525 values alone, rather than OR-ing them with N_EXT.
527 Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com)
529 * mipsread.c (parse_lines): Deal with negative extended line
532 * c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid
533 global symbol conflicts.
535 Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
537 * .gdbinit: Move 'set complaints' to top, so it runs even in
538 case we aren't debugging GDB.
539 * language.c (_initialize_language): Fix type check and range
540 check documentation strings.
541 * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
542 language.c can use it. (Though language.c should really not be
543 handling warnings/errors the way it does, FIXME.)
544 * symtab.c (lookup_primitive_type): const lint.
546 Bugfix from Peter Schauer:
547 * source.c (lines_to_list): Make signed, to avoid comparison
548 going unsigned and complaining that -3 is too high for 21 lines.
549 * stack.c (lines_to_list): Ditto.
551 Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
553 * Makefile.in (HFILES): Add minimon.h.
554 (VERSION): Roll version number to 4.0.95.
555 (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
556 New rules for building distributions. Normal distribution
557 is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
558 one level up from here; it calls make-proto-gdb.dir to build a
559 directory `proto-gdb' which is an image of the release. The old
560 `gdb.tar.Z' rule still works too.
561 * config.sub, configure: Roll in latest from ..
563 Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
565 * doc/gdbint.texinfo: Reorder contents; reorganize new-host,
566 new-target, and new-config chapters; fix minor typos; come closer
567 to usual GNU markup conventions for @file @samp @code @var.
569 Thu Sep 19 17:04:12 1991 Per Bothner (bothner at cygnus.com)
571 Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
572 * mipsread.c (parse_partial_symbols): Enter the name of all
573 structs/unions... into the psymtab so we can access them if the
574 symtab is not read in.
575 * mips-tdep.c: Remove some unneeded #includes.
576 * xconfig/dec3100: Add HAVE_STRSTR.
578 Thu Sep 19 15:14:23 1991 John Gilmore (gnu at cygnus.com)
580 * Makefile.in: Circumvent Sun Make bug on *-exp.tab.o.
581 * c-exp.y, m2-exp.y: Lint.
582 * m2-exp.y: Avoid using yytname[] which is a Bison-ism.
583 * valprint.c (val_print_fields): Check for stub type.
584 * mipsread.c (_initialize_mipsread): Avoid using
585 builtin_type_void at initialize time.
586 (mipscoff_symfile_read): use it now.
588 Wed Sep 18 15:55:51 1991 John Gilmore (gnu at cygnus.com)
590 Merge multiple-language support, and partial Modula-2 support,
591 from Andrew Beers <beers@cs.buffalo.edu>.
593 * i387-tdep.c: New file, consolidates most 80387 support,

612 * coffread.c (end_symtab): Use allocate_symtab.
613 (process_coff_symbol): #if 0'd for functions and params as above.
614 (read_enum_type): Recognize Modula-2 BOOLEAN.
615 * symtab.c (add_param_to_type): #if 0'd function to add a

687 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
689 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
690 entries are enclosed herein. Not all of these changes
691 have been merged into the master GDB sources -- check the
692 ChangeLog above here for the merge log.
694 Mon Jun 3 17:05:45 EDT 1991
696 m2-exp.y Created. Tested outside of GDB for a few days. Proper
697 operators were added, C specific operators and tokens
698 removed. yylex() revamped to some extent. Still things
699 missing from the grammar, such as sets.
700 Tested for two weeks in GDB v3.5.
702 Tue Jun 11 17:23:48 EDT 1991
704 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
705 so they are built-in. Sort of a hack.
707 Fri Jun 14 12:53:51 EDT 1991
709 m2-exp.y Added range checking for numeric constants. Any numeric
710 constant is assumed to be of builtin type INTEGER unless:
711 (1) it is octal or hexadecimal, in which case it is a
712 CARDINAL; (2) it is too big to fit into an INTEGER, in
713 which case it is a CARDINAL.
714 eval.c Added simple range checking for +, -, and * on integers.
715 Doesn't work very well for *, since 6 * 1,000,000,000 =
716 1,705,032,704, which fails the simple test of result >=
717 first_operand, no matter in what order the operands are.
719 Tue Jun 18 14:11:30 EDT 1991
721 Broke the parser into parts, one containing the C grammar and the other
722 containing code to be shared by all of the grammars.
724 The following files no longer exist:
729 The following files were added:
731 c-exp.y (The C grammar)
732 m2-exp.y (The Modula-2 grammar)
733 parser-code.c (Code that is shared by the above grammar)
737 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
738 now necessary to use the Bison compiler compiler, since it
739 will generate function/variable prefixes other than yy.
741 Tue Jun 18 16:47:49 EDT 1991
743 symtab.[ch] Added the external variable working_lang, than holds the
744 value of the current working language.
745 Added the ennumerated type language_mode, with the values
746 language_auto and language_manual, the former meaning that
747 GDB sets working_lang as needed, and the latter meaning
748 that the value of working_lang is totally under user
750 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
751 REAL, BOOLEAN and CHAR. Also added the type codes
752 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
753 utils.c Added set_language_command and show_language_command to
754 implement the GDB support commands "set language" and
756 expression.h A number of identifiers were added to the type exp_opcode
757 to facilitate Modula-2 builtin functions, integer
758 division, and array indexing.
760 Wed Jun 19 13:25:58 EDT 1991
762 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
763 if the language specified by working_lang requires the use
764 of strict typing of expressions. Eventually, even this
765 will be able to be changed by the user.
766 Added the macro RANGE_CHECK, which evaluates to non-zero
767 if the language specified by working_lang requires the
768 checking of a value against the domain of its type.
769 Eventually, even this will be able to be changed by the
771 language.[ch] Predicates involving types (simple_type, ordered_type,
772 same_type, integral_type, numeric_type, character_type,
773 boolean_type, float_type) are added. These predicates are
774 based on the current value of working_lang, and are handy
777 Wed Jun 19 15:39:34 EDT 1991
779 eval.c Added the function type_array_rank which computes the rank
781 valarith.c Added the funtion value_bool, which when given a integer
782 value.h value (ie. struct value *) as an argument, it returns a
783 boolean value (ie. struct value *) true if that integer
784 is non-zero, and a boolean value false otherwise.
785 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
786 will print out properly.
788 Wed Jun 19 16:36:34 EDT 1991
790 valops.c Added the function value_capitalize, which returns it
791 value.h argument capitalized if its argument is a lowercase
792 letter, or the argument unchanged if its argument is not a
794 valarith.c Added the function range_check_p, which returns non-zero
795 value.h if its value argument is between the integral bounds upper
797 Added the function range_check_enum_p, which makes sure
798 that its value argument is a valid member of the domain of
800 Added the function range_check_range_p, which makes sure
801 its value argument lies between the upper and lower bounds
802 of its type argument, which must be a ranged type.
803 Added the function check_array_index, which range and type
804 checks an index of an array.
805 Added the function value_multi_subscript, which computes
806 array[idx1,idx2...idxN], given a value array and an array
807 of values representing indicies.
808 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
809 unpack_long to work with TYPE_CODE_BOOL and
812 Wed Jun 19 18:04:08 EDT 1991
814 symtab.c Stored pervasive types in a structure and make
815 lookup_pervasive_type() a lookup function that was based
816 on working_lang. If lookup_pervasive_type() returned
817 non-zero, then that value was returned (a fix, since
818 before it simply wouldn't return the pervasive type.)
819 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
820 non-zero if the language specified by working_lang means
821 "conversion" when it says "cast".
822 valops.c Added the function value_real_cast(), which performs a
823 value.h *cast*, not a *conversion*, which is what value_cast()
824 does when it can. In particular,
825 value_cast(<float_type>,4) = 4.0, while
826 value_real_cast(<float_type>,4) = some mess.
827 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
828 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
829 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
830 and MIN on integral types. *NOTE*: These are currently
831 hardcoded to work only if there are 8 bits per storage
833 eval.c Made logical functions call value_bool to return a
834 properly typed boolean value, based on working_lang.
836 Thu Jun 20 11:55:27 EDT 1991
838 valprint.c Types now print out in a Modula-2 fashion. This works for
839 the cases when the type is printed out step-by-step, that
840 is, it doesn't work when the name of a structured type
841 (which includes the keyword "struct", etc.) is simply
843 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
844 since type specifications in C and Modula-2 are very
845 different. The C printing of a type is very recursive,
846 whereas in Modula-2 it is generally very simple. C has
847 type prefixes and suffixes, which have no real analogue in
848 Modula-2. Maybe type_print() should call a language
849 specific type printer. This is also advantageous if we
850 compile GDB to exclude some of the languages. We'll just
851 leave those functions out.
853 Thu Jun 20 16:57:10 EDT 1991
855 dbxread.c When reading the complete symbol table in (via
856 psymtab_to_symtab()), the number and types of function
857 arguments are added to a function type. define_symbol()
858 calls add_param_to_type() to accomplish this.
859 Assumption: when we come across a function definition
860 (N_FUN symbol with an 'f' or 'F' in the name), its
861 arguments will appear before another function definition.
862 When a function is found, a pointer to its type is placed
863 in the global in_function_type. Changes that
864 add_param_to_type() makes are to this global.
865 valprint.c The type of a function now includes (for Modula-2) the
866 types of its parameters.
867 eval.c Type checking and a check for the proper number of
868 arguments is now done for function calls. Not sure of the
869 impact this has on C++ member function yet.
871 Thu Jun 20 19:58:48 EDT 1991
873 valprint.c Rewrote the type printer. Broke it into two language
874 specific parts, adding the functions type_print_m2() and
876 An unfortunate consequence is this: if you debugging a C
877 program in Modula-2 mode (why?), info types does not work
878 well with regular expressions, since the types are printed
879 out in Modula-2 terminology, but stored in C terminology.
880 language.[ch] Added the functions new_type_last(), type_keyword(), and
881 type_sep() to aid in the printing of typedefs.
882 symtab.c Made the printing of typedefs as language independent as
883 possible through calls to new_type_last(), type_keyword(),
886 Fri Jun 21 11:50:26 EDT 1991
888 dbxread.c Check all incoming ennumerated types. If it looks like
889 Modula-2's BOOLEAN type, then change the type_code of the
890 type to TYPE_CODE_BOOL so we can process it as a boolean
892 valprint.c Replaced some of the 0x%x with calls to sprintf and
893 hexformat() in val_print().
894 language.[ch] Added the function hex_to_string(), which converts its
895 integral argument to a hexadecimal number (format is
896 language based) and returns the result as a string.
898 Mon Jun 24 12:25:07 EDT 1991
900 valprint.c Some functions call type_print_1() directly, instead of
901 value.h using type_print(), so they can specify where (column) to
902 print things. Since type_print() takes care of language
903 dependence, that needs to be called first. Added a
904 parameter depth to type_print() (so it is now like
905 type_print_1). Changed type_print to type_print_at, and
906 made type_print a macro that passes a depth argument of
908 symmisc.c Changed all calls to type_print_1 to calls to
910 Makefile.dist Made it possible to build GDB for a specific set of
911 depend languages. Do this by passing a definition for the macro
912 LANGS to make. LANGS should be a string containing a
913 space-separated list of language names (ie. LANGS="c m2").
914 The default is to build all languages. Note that grammar
915 files must follow the naming convention of <lang>-exp.y.
916 gdb.lang This holds the current value of the LANGS macro. It is
917 examined every time make is called, and is updated if
919 eval.c Added #ifdef _LANG_<lang> to these files.
920 expread.c Still need to add them to dbxread.c and coffread.c.
928 Mon Jun 24 16:33:11 EDT 1991
930 language.[ch] Added the functions hexformat_pre() and
931 hex_to_string_pre(), which take a prefix argument to
932 include in the format string. Thus, hexformat_pre("08") will
933 return "0x08x" (if the working language is language_c).
934 Made hexformat() and hex_to_string() calls to the above
935 with "" as the prefix argument.
937 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
938 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
939 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
940 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
941 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
942 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
943 valprint.c, vax-pinsn.c
945 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
946 calls to hexformat() and hex_to_string(). Format strings without
947 the leading "0x" were ignored.
949 depend Updated to take the above into account.
952 Tue Jun 25 15:27:18 EDT 1991
954 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
955 and type_check_t to keep track of the current state of
956 range and type checking.
957 main.c Added the variables range_mode, range_check, type_mode,
958 and type_check to record the current state of range and
959 type checking. Added initialization code to main().
960 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
964 Tue Jun 25 17:57:08 EDT 1991
966 dbxread.c process_one_symbol() updates the variable (enum language)
967 source_lang based on the extension of the filename
968 contained in the N_SO sybmol that started this symtab.
969 When end_symtab() is called, the value of source_lang is
970 put into the language field.
971 stack.c select_frame() sets working_lang (and possibly type_check
972 and range_check) to the language field of the symtab
973 associated with the frame that is selected if working_mode
974 is language_auto. If working_mode is language_manual, a
975 warning is printed and working_lang is not set.
976 language.c Added the function set_type_range(), which sets the value of
977 type_check and range_check (if their modes call for
978 automatic setting) based on the current value of
979 working_lang. A non-zero argument will cause the current
980 settings to be output.
983 Wed Jun 26 14:51:40 EDT 1991
985 eval.c Added range checks on assignment.
986 m2-exp.y Added the grammar for sets to the language. Currently,
987 these do not do anything except print an error message.
989 Wed Jun 26 17:01:04 EDT 1991
991 m2-exp.y Added the ability for parse_number() to parse negative
992 numbers. A global flag is set upon encountering a unary
993 minus. This was done to make, for example, 1 parse as a
994 CARDINAL, and not as an integer, per Wirth's examples in
995 Programming in Modula-2 ed.4.
996 valprint.c Added support for "set radix 2" by then setting
997 output_format to 't'.
998 eval.c Implemented range checking on subrange types. Added calls
999 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
1000 Implemented MIN and MAX for ennumerated types. The
1001 minimum value of an ennumerated type is defined by Wirth
1002 as the first identifier, and the maximum as the last.
1003 m2-exp.y Made octal numbers ending with "B" be characters and those
1004 ending with "C" be numbers, per Wirth's book. (p. 34)
1006 Thu Jun 27 14:11:52 EDT 1991
1008 stack.c select_frame() now only sets working_lang, it does not
1009 notify the user. If working_mode is language_manual, then
1010 a warning is issued once.
1011 main.c At the end of each call to execute_command(), working_lang
1012 is checked against the local static (enum language)
1013 current. If they differ and working_mode is
1014 language_auto, the new settings of language, type and
1015 range checking are printed out.
1016 stack.c Modified frame_info() to include the language of the
1017 current frame in the output of "info frame".
1018 language.[ch] Added the function language_str() which returns the name
1019 of the current language.
1021 Fri Jun 28 15:33:14 EDT 1991
1023 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
1024 the language. INCL and DECL currently cause an error,
1025 since sets are not implemented yet. INC and DEC are
1026 implemented as PREINCREMENT/PREDECREMENT with one
1027 argument, and as ASSIGN_MODIFY with two arguments.
1028 eval.c Added type checking to the above cases.
1029 value.h Added not_lval_constant to the lval_type ennumerated type.
1030 not_lval_constant means that the value is a constant
1031 value; that is 3 or 'a' or TRUE, not as in a constant
1032 identifier. This is used to help coerce numbers such as 3
1033 to either signed or unsigned numbers.
1034 valops.c Added the function value_coerce_constants() which coerces
1035 constant integers as following: if one is a constant and
1036 the other is not, the constant's type is set to the type
1037 of the other argument. If both are constants and one is
1038 signed, the other is converted to a signed constant.
1040 Sat Jun 29 17:26:29 EDT 1991
1042 valarith.c Added a better range checker. It now checks range
1043 (successfully) on integral operations [+-] (signed and
1044 unsigned) for any C sized type. Still does not work well
1045 for multiplication.)
1046 int_in_size() returns an integer that is coerced to fit into
1047 specified number of bytes.
1049 Mon Jul 1 13:04:14 EDT 1991
1051 language.[ch] Added the function binop_result_type(), which returns the
1052 builtin (struct type *) type that would be the result of a
1053 binop on the two values V1 and V2.
1055 Wed Jul 3 19:22:53 EDT 1991
1057 source.c Extended source_info() to include the source language in
1058 the output from "info source".
1060 Fri Jul 5 13:48:52 EDT 1991
1062 utils.c Moved the support functions for the GDB set/show commands
1063 dealing with language into language.c.
1064 language.c Added the function language_info(), which displays info
1065 about the current working language, type and range check
1066 settings. Called via the GDB command "info language".
1067 Added an initialization routine _initialize_language(),
1068 that sets defaults for the language, type and range
1069 variables and sets up the new GDB commands.
1070 main.c Language setup moved to language.c.
1073 Mon Jul 8 10:10:22 EDT 1991
1075 valarith.c Debugged the range checker for arithmetic. Still does not
1076 work for multiplication very well.
1078 Mon Jul 8 12:40:37 EDT 1991
1080 language.[ch] Added the function value_true() which returns non-zero if
1081 its argument represents a boolean true value.
1082 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
1083 check the truth of an expression.
1085 Thu Jul 11 12:51:34 EDT 1991
1087 language.[ch] Added the predicate structured_type(), which returns
1088 non-zero if the argument is a structured type.
1089 Added the predicate pointer_type(), which returns non-zero
1090 if the argument is a pointer type.
1091 eval.c Added the ability to do addition and substraction on
1092 pointers and integers. This case simply bypasses the
1095 Thu Jul 11 14:41:42 EDT 1991
1098 Added the symbol N_DEFD (0x4a) which is a definition
1099 module dependency that is used by the GNU Modula-2
1100 compiler and the linker. It is not important to GDB,
1101 except that [dbx|coff|mips]read.c should ignore these
1104 Fri Jul 12 16:07:00 EDT 1991
1106 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
1107 0 in val_print(). Also added statements to the else part
1108 to coerce type (argument to val_print) to a pointer type
1109 if it is an "array of unspecified length".
1110 valops.c Added the function value_m2_string(), which returns a
1111 (value) value which is a constant string, whose type is
1112 (ARRAY [0..n] OF CHAR). The length field of the type
1113 structure is set to zero, so it will be interpreted as an
1114 "array of unspecified length".
1115 stack.c Moved the language/frame mismatch check to
1116 main.c:execute_command().
1117 main.c The working language is recorded each time
1118 execute_command() is executed. If working lang has
1119 changed during its execution, then the new
1120 language/type/range info is printed out for the user. If
1121 the working language does not match the language of the
1122 frame, a warning is issued.
1124 Sat Jul 13 16:16:39 EDT 1991
1126 eval.c Moved all the type-checking stuff for operators to
1127 language.[ch] language.c. This is so we can keep language-specific
1128 stuff (like for what type operators are defined) in
1130 language.[ch] Added the function binop_type_check(), which checks to see
1131 if its two (value) arguments are type-compatible with its
1132 opcode argument. The opcode should represent an operation
1133 involving an operator. Also added the macro function
1134 unop_type_check, which calls binop_type_check with a
1135 NULL second argument.
1136 expprint.c Added Modula-2 operators to the op_print_tab, so info
1137 expression.h break works correctly. Also added "op_string", which
1138 returns the string corresponding to the (enum exp_opcode)
1139 opcode that is its argument.
1142 Sat Jul 13 18:26:18 EDT 1991
1144 coffread.c Added code to record the type of function arguments with
1145 each paricular function. Code is very similar to that
1147 dbxread.c Moved add_param_to_type() to symtab.c
1148 symtab.[ch] Added function add_param_to_type() from dbxread.c
1150 *** NOTE: The above additions have not been tested.
1152 Mon Jul 15 12:50:47 EDT 1991
1154 langauge.[ch] Added the functions type_error and range_error, which work
1155 like error() except if the type/range mode is set to
1156 *_mode_warn, then they do not do a return_to_top_level(),
1157 but merely print a warning.
1158 Also changed [set|show]_[type|range]_command() to support
1159 the new "warn" feature.
1161 Thu Jul 18 17:50:54 EDT 1991
1163 mipsread.c Added code to record the type of function arguments with
1164 each particular function. Code is very similar to that
1167 *** NOTE: The above additions have not been tested.
1169 Fri Jul 19 11:19:10 EDT 1991
1171 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
1172 UMIN_OF_SIZE, which when given a size of a numeric type,
1173 return the maximum and minimum value it can hold. UMAX...
1174 and UMIN... return the result for unsigned types.
1175 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
1176 struct types. They call above macros.
1177 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
1178 avoid a name conlict with the above.
1179 c-exp.y Added range checking on numeric constants in
1180 parse_number() for completeness.
1181 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
1182 return 0 if working_lang is not language_c.
1184 Thu Aug 8 14:17:22 EDT 1991
1188 breakpoint.c Documentation strings of some commands changed to
1189 eliminate the references to the C language where
1192 Tue Aug 13 15:48:03 EDT 1991
1194 m2-exp.y Added qualified identifiers to the grammar. The semantics
1195 are slightly different from those of the GDB operator ::
1197 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
1198 type_exp, where type_exp is any valid type expression.
1200 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
1201 printcmd.c Modified ptype_command() so it actually parses the input
1202 (necessary for type expressions with scope qualifiers).
1203 Added the function ptype_eval() which expects an
1204 expression composed of one OP_TYPE element.
1205 *.[ch] Replaced all occurences of parse_c_expression with
1207 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
1209 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
1211 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
1213 Small fixes from Peter Schauer:
1215 * infrun.c (child_attach): Lint.
1216 * solib.c (find_solib): Handle shared libs version 2.
1218 Small fixes from David Wood:
1220 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
1224 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
1225 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
1227 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
1228 chars_per_line is at maximum (user typed `set width 0'). Fix
1229 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
1231 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
1233 * coredep.c: include ptrace.h where necessary.
1234 * mipsread.c(parse_lines): fix unsigned char problem that was
1235 messing up line numbers on SGI's and possibly other MIPS based
1237 * infrun.c (child_create_inferior): use better test to check
1238 return val from setpgrp().
1239 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
1240 for sgi/irix support.
1242 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
1244 * mipsread.c (parse_symbol): Put non-static procedures
1245 in the global block.
1247 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
1249 Patch together `text_start' and `text_end' for 29K port.
1251 * exec.c (exec_command): If NEED_TEXT_START_END, define the
1252 variables and set them based on the exec file.
1253 * am29k-tdep.c: declare text_start.
1254 * valops.c (call_function_by_hand): declare text_end.
1256 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
1257 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
1258 because machines that do this will also have to know to
1259 set NEED_TEXT_START_END. Besides, it was a redundant way to
1261 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
1262 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
1263 NEED_TEXT_START_END.
1265 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
1267 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
1269 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
1270 Pass MUNCH_DEFINE to munch whenever we run it.
1271 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
1272 format string; use 0x%x instead.
1273 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
1274 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
1275 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
1276 * inflow.c: Handle `short' process group IDs.
1277 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
1278 and check for ptrace errors.
1279 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
1280 (coff_symfile_init): Initialize text_bfd_scnum.
1281 (read_coff_symtab): Use it to find the text [and absolute?] sections.
1282 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
1283 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
1284 Merge target arm case with other "easy" cases. Add target
1285 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
1286 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
1288 * minimon.h, remote-adapt.c, remote-mm.c: Add.
1289 * munch: Cope with RT/PC putting fns in data segment.
1290 Restore ability to override `nm' by specifying MUNCH_NM.
1291 * xconfig/rtbsd, xconfig/ultra3: New host systems.
1292 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
1293 and remote-adapt. Remove encapsulated coff #define's (the
1294 support should go in BFD, and gdb shouldn't know or care).
1295 * tconfig/a29k-kern: Same, but for remote kernel debugging.
1296 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
1297 * tm-29k.h: Update BADMAG (though it should go away).
1298 Allow the register definitions to be overridden in another
1299 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
1300 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
1301 DUMMY_SAVE_GR96, for handling kernel calling conventions
1302 that use GR64+ rather than GR96+.
1303 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
1304 remote debugging of Ultra3 kernel. Includes tm-29k.h and
1305 overrides various things.
1307 * remote-mm.c (mm_attach, mm_wait): Handle attach like
1308 child_attach does, making a clean stop in the newly attached
1310 * remote-eb.c: Lint.
1312 * coffread.c: Make coffread independent of any particular
1313 variant of COFF. Avoid #include-ing any particular one except
1314 internalcoff.h. BFD now passes key values for symbol reading
1315 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
1316 and the symbol masks and shifts); use them.
1317 Remove obsolete end_of_text_addr.
1319 * exec.c: Remove unused include files.
1321 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1323 * Makefile.in (documentation targets): Pass $(M4).
1324 Bugfix from eggert@twinsun.com (Paul Eggert).
1326 * stack.c (down_silently_command): Check for stack existence.
1328 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1330 * Makefile.in (VERSION): Update to 4.0.3.
1332 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1334 * core.c (core_file_command): Print frame at coredump with
1335 its level number, by calling print_stack_frame.
1336 * frame.h: Add selected_frame_level, print_stack_frame.
1337 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
1338 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
1339 Change print_sel_frame and print_selected_frame callers to
1342 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
1343 * symfile.c (free_named_symtabs): Ditto.
1344 * main.c (main): wrap_here needs an arg.
1345 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
1346 (solib_add): Avoid noise.
1347 (solib_create_inferior_hook): Lint.
1348 (sharedlibrary_command): Move dont_repeat to here.
1349 * utils.c (error): Call wrap_here to force buffered output.
1351 Small patches from Peter Schauer:
1353 * coffread.c (start_symtab): Free any existing line_vector before
1355 (read_coff_symtab): Ditto for type_vector.
1357 * source.c (lines_to_list): New variable, replacing function.
1358 (all uses): Use as variable.
1359 (_initialize_source): Add 'set listsize' and 'show listsize'.
1360 * utils.c (lines_to_list): Remove function.
1361 * stack.c (print_frame_info): Use as variable.
1362 * defs.h (lines_to_list): Remove declaration.
1364 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1366 * breakpoint.c (insert_breakpoints): Restore warning about
1367 the program might be running in another process, but only for
1368 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
1369 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
1371 * utils.c (error): if error_pre_print is set, print the string
1373 * main.c (main, print_gnu_advertisement, print_gdb_version):
1374 Reformat legalese so it always prints, but acts as an "I'm here"
1375 message while symbols are being read. If any errors occur,
1376 print a few newlines to set off the message and start it at the
1377 left margin. Remove mention of "help" command, and don't yak
1378 about symbol reading.
1379 (catch_errors): Error string is now printed first in case of
1381 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
1382 suggest the "help" command.
1384 * Makefile.in (VERSION): Set to 4.0.2.
1386 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
1388 * .gdbinit: Remove useless "rr" command. Set complaints
1389 to 1 for people debugging gdb.
1391 * breakpoint.c, remote-vx.c: Reword strings printed by
1392 catch_errors callers.
1394 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
1396 * WHATS.NEW: "history write -> history save". Doc "write on/off".
1397 (Fix from kenc@viewlogic.com.)
1399 Fix some infrastructure to be able to cope with host and target
1400 machines with different sized basic types (ints, ptrs, etc).
1401 (Idea from pierre@la.tce.com (Pierre Willard).)
1403 * values.c (value_from_longest): Rename from value_from_long.
1404 Handle pointer types as well as integers, so that targets with
1405 different pointer sizes from the host can be accomodated.
1406 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
1407 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
1408 uses of value_from_long to value_from_longest.
1409 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
1410 the correct pointer type to value_from_long{est}.
1412 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
1414 * remote-vx.c: Remove obsolete code for calling functions via
1415 vxworks kludge interface (it referenced value_from_long).
1417 * valops.c (value_string): Find malloc with lookup_misc_func, not
1420 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1422 Make writing to files work properly. (Fixes to BFD are also needed.)
1424 * core.c (core_open): Open file ourselves, read or r/w, depending on
1425 write_files. Use bfd_fdopenr.
1426 * gdbcore.h (write_files): New variable.
1427 * exec.c (write_files): Define variable, add set&show for it.
1428 (exec_file_command): Use write_files to open for read or r/write.
1430 Make shared library reading happen automatically. These changes
1431 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
1433 * inferior.h (stop_soon_quietly): Add to exported variables.
1434 * infrun.c (child_create_inferior): call solib hook, if defined.
1435 (child_attach): call solib hook, if defined.
1436 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
1437 (find_solib): Use lookup_misc_func rather than hand-rolled.
1438 (symbol_add_stub): New stub for catch_errors.
1439 (solib_add): Avoid output if !from_tty. Catch errors rather
1440 than just calling symbol_file_add and bombing.
1441 (solib_create_inferior_hook): Interface with the target process
1442 to let it read and alloc shared libs, then figure out what it did.
1444 * core.c (validate_files): Fix typo, soften warning.
1445 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
1447 * utils.c (fputs_demangled): Avoid duplicate printing if
1448 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
1450 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
1451 (Fix from pierre@la.tce.com (Pierre Willard).)
1453 * main.c (catch_errors): Change argument to a char * from an int,
1454 since a char * can point to a struct full of glop, but an int
1455 is not guaranteed to be able to hold a pointer.
1456 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
1457 breakpoint_re_set_one, breakpoint_re_set): Adapt.
1458 * core.c (core_open, solib_add_stub): Adapt.
1459 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
1461 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1463 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
1464 by adding .NOEXPORT target.
1466 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1470 * Makefile.in (VERSION): Roll to 4.0.
1471 (gdb.tar.Z): Make refcard.ps as well, for shipment.
1473 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1475 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
1478 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
1481 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
1483 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
1484 reflect above name change
1486 * WHATS.NEW: correct pointer to refcard.
1488 * doc/gdb.texinfo: update New Features, Installing
1490 * doc/gdbint.texinfo: add short description of configure +template
1492 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1494 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
1496 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
1498 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
1499 tar file, add dependencies for referenced doc files.
1501 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
1503 * coffread.c, symfile.c, stack.c: saberized.
1505 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1507 * doc/refcard.tex: permuted Essential Commands sec
1509 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
1511 set/show symbol-reloading
1512 default set complaints 0
1514 RET-repeat disabled after prompted long displays
1515 processID (attach) interpretation of 2nd GDB cmdline arg
1517 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
1519 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
1520 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
1521 breakpoint.c, main.c: lint.
1523 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1525 Install new configuration scheme for GDB and friends.
1527 * config.sub: Translate ordinary names to three-part names.
1528 * configure: Use three-part names internally.
1529 * configure.in: Translate three-part names to filenames.
1531 * README, WHATS.NEW: Update for gdb-4.0.
1532 * Makefile.in: Roll VERSION to 3.99.
1534 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
1536 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
1537 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
1538 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
1539 to single structures rather than arrays; when passing
1540 their address, use &. This avoids trouble with bdead compilers.
1541 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
1542 instead. This avoids portability headaches.
1543 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
1545 * source.c (open_source_file): Avoid ANSI const bdeath by
1546 skipping declaration and then casting result value.
1547 * tm-hp300bsd.h: Clarify comment.
1548 * utils.c (strstr): Result is const char *; ANSI bdeath.
1549 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
1550 since system include file defines it differently from "defs.h",
1551 though the two are equivalent for our purposes.
1552 * tconfig/hp300bsd: Add m68k-tdep.o.
1554 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1556 * tconfig/sun*4: Remove warnings about system assembler.
1558 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1560 * mcheck.c: Avoid warning about undeclared abort fn.
1561 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
1562 it causes recursive calls to error() when used in cleanups.
1563 To do so requires that we make it a function, so we do.
1564 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
1565 * utils.c (do_cleanups): Remove the current cleanup from the
1566 chain *before* calling it, in case error() is called from it.
1567 The result won't be pretty, but won't be an infinite loop either.
1569 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
1571 * dbxread.c (read_struct_type): Grok anon structs for C++.
1572 (vb_name, vptr_name): Null terminate these strings.
1574 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1576 Minor bug fixes from BSD Net2 gdb:
1578 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
1579 returns 0, there is no previous frame.
1580 * breakpoint.c (commands_command): If !from_tty, don't call
1581 input_from_terminal_p().
1582 * dbxread.c (record_misc_function): Speed up slightly.
1583 (compare_psymbols): Ditto.
1584 * infcmd.c (do_registers_info): Take a second argument to
1585 determine whether to print float registers. "info registers"
1586 does not do so anymore. "info all-registers" does, now.
1587 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
1589 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
1590 * inflow.c (initialize_inflow): Set tflags_ours correctly.
1594 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
1595 executing_breakpoint_commands if we are interrupted by error.
1596 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
1597 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
1598 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
1599 catch_errors() so we can setup the frame regardless of whether
1600 the shared libs work.
1601 * ieee-float.c (double_to_ieee_extended): Get exponent from
1602 right place in little-endian systems. From John Carey.
1604 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1606 * main.c: Remove unused terminating_signals and catch_termination().
1607 (long_options): Terminate with a zero element.
1608 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
1609 (gdb_readline): Make call-compatible with readline.
1610 (init_signals): Improve comments re vfork vs. signal.
1612 * utils.c (prompt_for_continue): Use new gdb_readline().
1613 If we prompt for continuation, we don't let CR repeat the previous
1614 command, once we get back to a prompt. It's too easy to keep
1615 hitting CR, expecting "--more--" prompts, and have some long
1616 command start repeating on you.
1618 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1620 * blockframe.c (frameless_look_for_prologue): Speed up by
1621 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
1622 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
1623 Define two variants, one faster.
1624 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
1625 and return zero, rather than giving an error.
1626 (setup_arbitrary_frame): Initialize the PC in the new frame.
1627 (skip_prologue): Add a second arg saying whether we're just
1628 checking for a frameless function or not.
1630 * core.c (core_open, core_close, core_xfer_memory): Move
1631 section table pointers and bfd* into the target_ops.
1632 (core_open): Allow errors in shared lib reading, etc.
1633 (core_files_info): Describe shared library sections.
1635 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
1636 exec_files_info, set_section_command): Move section table
1637 pointers and bfd* into the target_ops.
1638 (add_to_section_table): Add BFD to section table.
1640 * target.c (target_xfer_memory, target_info): Pass target to
1641 xfer_memory and target_info functions.
1644 * gdbcore.h: Move struct section_table.
1645 * target.h: New home of struct section_table.
1647 * solib.c (solib_add): New argument is the target_ops whose
1648 section list is to be added to, if any. Reallocate the
1649 sections in that target to add any that come from shared libs.
1650 (throughout) so_sections renamed to sections.
1651 (solib_xfer_memory): Deleted.
1652 * tm-sunos.h (SOLIB_ADD): Add target argument.
1653 (SOLIB_XFER_MEMORY): Delete.
1655 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1656 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
1657 from target_ops. It's the same on all targets. Add two section
1658 pointers to target_ops.
1660 * stack.c (find_relative_frame): Dump ancient algorithm for
1661 "down", just use handy "next" pointers.
1662 (frame_command): Don't error if there is no stack; let user
1665 * inflow.c (new_tty_prefork, new_tty): New prefork routine
1666 modifies static state in the parent process; new_tty itself
1667 runs in the child and modifies the child's file descriptors
1668 to match the saved static state.
1669 * infrun.c (child_create_inferior): Call new_tty_prefork,
1672 * infptrace.c (child_xfer_memory): Add ignored target arg.
1673 * remote-eb.c (eb_xfer_inferior_memory): ''
1674 * remote-nindy.c (nindy_xfer_inferior_memory): ''
1675 * remote-vx.c (vx_xfer_memory): ''
1676 * remote.c (remote_xfer_memory): ''. Rename from
1677 remote_xfer_inferior_memory.
1679 * main.c (main): Only try to attach "corefile" argument if
1680 it starts with a digit.
1682 * symfile.c (symbol_reloading): New "set/show" variable.
1683 (symbol_file_add): Shorten message about symbol reading.
1684 (add_symbol_file_command): Merge with add_syms_addr_command,
1685 since this should work on all targets now.
1686 (stop_whining): Default to zero, to shut up complaints
1687 about bad symbol tables on many systems.
1688 (free_named_symtabs): Just exit unless symbol_reloading.
1690 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
1691 and add comment explaining shared library screw.
1693 * source.c: #if defined => #ifdef.
1695 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1697 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
1699 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1701 * doc/rdl-apps.texinfo: provide default readline-appendix finder
1702 (doc/Makefile knows how to make one for local config)
1704 * Makefile.in: use doc/Makefile for doc targets
1706 * doc/Makefile: GDB documentation now has its own Makefile
1707 doc/refcard.tex: renamed from "gdbrc.tex"
1708 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
1709 doc/gdbint.texinfo: add markup in "Cleanups" chapter
1712 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1714 * values.c (baseclass_addr): When reading target memory, use the
1715 length of the basetype, not the upper type. We've only malloc'd
1716 enough space for the basetype, leading to errors in free().
1718 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
1719 ends up as a function specially, since we know the actual type of
1720 the pointed-to address. This (somewhat) fixes display of
1721 expressions that include misc_function_vector names. Try `cond 1
1722 !strcmp("a","b")' then `i b'.
1724 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
1725 The child can be proceeded from inside wait_for_inferior in
1726 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
1727 getting skipped in that case.
1729 * expprint.c (print_subexp): Use filtered output, since the
1730 subroutines we call use it, otherwise the output is horribly
1731 mangled, since output of wrappable stuff comes out late.
1733 * Makefile.in: Bump VERSION to 3.98.1
1735 * infrun.c (child_create_process): Use execlp to find the
1736 shell to exec our target program. This requires some fiddling
1737 with `environ' since there is no execlpe().
1739 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1741 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
1742 Minor rearrangement of refcard permits two new make targets--
1743 gdbrc.dvi DVI output for refcard, using CM fonts
1744 gdbrc.ps PostScript refcard, using PS fonts
1746 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1750 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
1751 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
1753 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1755 * doc/gdb.texinfo: last changes for release.
1756 Minor typo and formatting fixes; incorporated most fixes remaining from
1757 filed mail commenting on earlier drafts.
1759 Added warnings: pipes don't work in run command;
1760 conditions are converse of assertions;
1761 step over fn without debug info goes to next fn;
1762 vars may have "wrong" values near fn entrance, exit
1764 Added example from Kingston on printing repeated nonadjacent values
1766 Added explicit mention that in Emacs gdb mode C-c and C-z are like
1767 shell mode for signals
1769 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
1770 doesn't sound so much like its parent "Stopping and Continuing"; also
1771 moved entries on continue to top of section, so they don't get lost.
1773 Improved installation directions in appendix, added manual formatting
1776 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1778 * configure.in: Remove xm.h and tm.h even if we aren't linking
1779 new ones, so "./configure sun4; ./configure none" does the right
1780 thing. Assume that alldeps.mak and depend are already built in
1781 srcdir, and avoid running "make" (particularly "make depend",
1782 which involves "gcc") from inside configure. Build Makefile
1783 directly rather than building Makefile.conf first.
1784 * configure: Regenerate with above changes.
1785 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
1786 to 3.98. Revise gdb.tar.Z procedure to produce a file
1787 called gdb-$(VERSION).tar.Z but which unpacks into a
1788 directory called "gdb". Move non-source files out of
1789 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
1790 (depend): Don't try to do "gcc expread.y".
1791 (expread.o): Update dependencies by hand.
1793 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1796 Fixed a variety of small typos that prevented info from formatting
1797 cleanly; altered too-long heading for GPL Appendix, as discussed
1798 w/RMS; Changed date on cover to July 91.
1800 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1803 (1) Applied some fixes due to comments from Larry Breed (easier ones
1804 through chapsec 5.2)
1805 (2) Eliminated use of @footnote---had my doubts about it anyways, and
1806 it's broken in latest texinfo
1807 (3) Introduced *some* use of [] for optional arguments, where
1808 explanation is not simpler by listing cmd w arg and cmd w/out arg
1809 separately. Still not using @deffn.
1810 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
1811 couple of headings are too long. Need patches to texinfo or revision
1814 * Partial update to README (which still needs work for this
1815 release!): (1) use of configure corrected for new script,
1816 (2) "make gdb.dvi" and "make gdb.info" mentioned.
1818 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
1820 * symtab.c (lookup_symbol): Don't complain right off about
1821 no debug symbols; use the misc function vector first.
1822 (list_symbols): Use misc function vector to find symbols
1823 that don't have debug info, and print them.
1824 (find_pc_symtab): Temporarily avoid fatal() when psymtab
1825 PC range doesn't match symtab PC range, as it does on the
1826 MIPS because our symtab reading isn't perfect.
1828 * dbxread.c (dbx_symfile_read): Make warning about
1829 "no debug symbols" slightly nicer.
1831 * source.c (select_source_symtab): If "main" symbol exists,
1832 but decode_line_spec can't find line info, don't just return
1833 a zero; try other source symtabs or give an error.
1835 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
1836 their low addresses first, then rip through fixing high addrs.
1838 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
1839 <runene@ifi.uio.no>.
1840 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
1842 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1844 * Minor, mostly mechanical, cleanup of doc subdir for clean
1845 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
1846 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
1848 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
1850 Mostly MIPS and general symbol-reading fixups.
1852 * doc/gdbint.texinfo: Add documentation on symbol-reading
1855 * mipsread.c: Remove kludges around #include "ecoff.h".
1856 Remove redefinitions of a_magic, etc, no longer used.
1857 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
1858 Fix global overview comments to match symfile.c protocol.
1859 (mipscoff_new_init): Eliminate cur_hdr if we have one.
1860 (mipscoff_symfile_read): Eliminate unused code. Avoid
1861 sorting all the symtabs, when all we have read here is psymtabs.
1862 The symtabs are sorted as they are created anyway. Tell
1863 condense_misc_bunches whether we're mainline.
1864 (psymtab_to_symtab_1): Pass filename when recursing, to make
1865 stack trace more informative.
1866 (parse_partial_symbols): Assume cur_hdr as argument.
1867 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
1868 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
1869 the TYPE_NAME of char *, since that's done in symfile.c.
1870 (free_numargs, parse_symbol, add_symbol, add_block,
1871 shrink_linetable): Declare these fns void.
1872 (upgrade_type): Convert tree of if's to switch. Clean up
1873 bogus "off == 0" handling with a complaint. Avoid setting
1874 field bitpos and bitsize of array with lower and upper bounds.
1875 Check specified bitsize of elements against their actual type's
1876 bitsize, and complain if different. Complain about unknown
1878 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
1879 (psymtab_to_symtab_1): Print names of subsidiary files that
1880 are being read in. FIXME, we read far too many files. This code
1881 is not the problem, the problem is in parse_fdr where the psymtabs
1883 (cross_ref): Result should indicate that we used one aux entry
1884 normally, or two if we encountered a "next" entry. This used
1885 to leave the caller pointing at the wrong aux entry.
1886 (add_symbol): If overflowed cur_block, reallocate it larger,
1887 chase all pointers to it, and complain(), rather than clobber memory.
1888 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
1889 (new_field): Only allocate one field initially, not two.
1890 Pull ++ out of macro argument. Simplify.
1891 (_initialize_mipsread): Avoid initialization of importd
1892 global_psymbols and static_psymbols.
1894 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
1895 to properly set pst->symtab; avoid searching for it.
1896 (symfile_fns): Improve comments, add a FIXME.
1897 * dbxread.c: Update comments to reflect symfile protocol.
1898 (read_ofile_symtab, end_symtab): Return the symtab.
1899 (psymtab_to_symtab_1): Set pst->symtab.
1901 * coffread.c (coff_symfile_read): tell condense_misc_bunches
1902 whether we're mainline.
1904 * symfile.h (sym_fns): Remove unused sym_discard member.
1905 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
1907 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
1908 the environment variable is not.
1909 * infcmd.c (finish_command): Use filtered printfs.
1910 * cplus-dem.c: Add struct tags to a few unnamed structs.
1911 * valops.c (value_coerce_array): Improve comments.
1912 * valprint.c (type_print_varspec_suffix): Print array size only
1913 if greater than zero.
1914 * m88k-tdep.c: Shift some lines left by one space, that had
1915 apparently been trashed at some point.
1916 * TODO: More things to do, a few got done.
1918 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1920 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
1921 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
1923 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
1924 * expread.y, findvar.c, symmisc.c: Ditto.
1925 * printcmd.c (address_info): Update printed forms of LOC_
1926 symbols. Elim LOC_EXTERNAL.
1927 (print_frame_args): Keep track of param stack offsets before
1928 re-looking up to find the local register param is kept in.
1930 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
1931 Further integration of mipsread into gdb. Eliminate unused
1932 routines, duplicate declarations. Handle static symbols in
1933 psymtabs as well as external symbols. When reading symtabs,
1934 insert symbols into the correct block (global, static, or a local
1936 (read_mips_symtab, parse_partial_symbols): Don't pass useless
1938 (mipscoff_symfile_read): Don't call select_source_symtab.
1939 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
1940 rather than SYMBOL_VALUE.
1941 (parse_external): Comment clobbering of top_stack.
1942 (parse_partial_symbols): Update comments. Allocate and parse
1943 static symbols as well as external symbols. FIXME, enum values
1944 are not handled in this pass, but should be. Inline new_psymbol.
1945 Use SYMBOL_VALUE_ADDRESS.
1946 (psymtab_to_symtab_1): Read symbols into global static block
1947 by default (until enter some function's local block context).
1948 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
1949 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
1951 * source.c (select_source_symtab): Select a source symtab
1952 from either the symtabs or, failing that, the psymtabs.
1953 (list_command): Update error message.
1954 (forward_search_command, reverse_search_command): Use getc, not
1955 fgetc, for speed. FIXME, add comment about buffers that die if
1956 overrun by long line.
1958 * values.c (unpack_field_as_long, modify_field): Avoid shifting
1959 by an entire word, which is not portable, if we have a 32-bit
1960 field. (Code in dbxread.c already turns such bitfields, if
1961 aligned, into ordinary ints, but fixing this will help for other
1962 symbol formats and for future changes.)
1963 * core.c (core_open): Handle ANSI const brain death.
1964 * utils.c (vprintf): Fix varargs typo.
1966 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1968 * findvar.c (find_var_value): Handle &function better.
1969 * TODO: Document work needed on &fn and &array.
1970 * printcmd.c (print_address_symbolic): New arg is the prefix
1971 to print if a name is printed.
1972 (print_address_demangle): Honor "set print address" now.
1973 Use new arg above to improve spacing of output.
1974 * valprint.c (val_print): When printing function pointers,
1975 print symbolic form too.
1976 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
1978 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1980 * core.c (memory_error): Reword error msg to mislead less.
1982 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
1984 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
1985 parse_partial_symbols): Use newer BFD internals (external_filehdr
1986 and external_aouthdr), byte-swap the fields that we care about
1987 before using them, and make the file header data local to
1988 read_the_mips_symtab rather than global.
1990 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
1992 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
1993 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
1995 * main.c (command_line_input): Flush stdout and stderr
1996 before every call to readline. This reportedly fixes a bug
1997 that comes up in Sys V running emacs-gdb and/or xxgdb,
1998 when stdin/out are pipes or sockets.
2000 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2002 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
2003 Avoid declaring Makefile dependencies, because GNU Make stupidly
2004 tries to update it if we do.
2006 * coffread.c: Revise for minor changes to bfd internal coff
2009 * configure: If -template= is given a relative path, make it
2010 absolute before recurring in subdirectories.
2012 * configure, configure.in, Makefile.in: Install "configure" script
2013 as replacement for config.gdb.
2014 * config.gdb, Makefile.dist, Makefile.sdir: Remove
2015 * README: Update for configure, mostly. FIXME.
2017 * Add dec3100 as equivalent to littlemips. Indicate in all host &
2018 target config files that they are for the host. When the lines
2019 get copied into the Makefile, this makes it more obvious what's
2022 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2024 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
2025 tabs, which end up in the disassembler output inadvertently.
2027 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
2029 Make it compile cleanly in an ANSI GCC2 environment.
2031 * blockframe.c: <stdio.h>
2032 * cplus-dem.c: free takes a void *, ifdef __STDC__
2033 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
2035 * defs.h (alloca): Avoid doing anything if alloca already def'd.
2036 * stddef.h, stdlib.h: Remove these files.
2037 * symtab.c: Avoid declaring qsort, close.
2038 * symfile.c: Avoid declaring close.
2039 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
2040 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
2042 Assorted other changes.
2043 * dbxread.c: include "libaout.h", not "liba.out.h".
2044 * printcmd.c (print_frame_args): Set recurse properly for
2045 indentation of struct and array parameters.
2046 * valops.c (value_cast): Allow cast to void.
2047 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
2048 single_step() in a target-independent fashion.
2049 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
2050 set up to be ready to continue. This makes us target independent.
2051 * infptrace.c (child_resume): Remove call to single_step; now
2052 can single step a SPARC target of any kind.
2054 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2056 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
2057 docn into separate sections---basically chapters, plus two loose
2058 pieces that can be configured to go in different places. This
2059 allows GNU m4 to preprocess the manual without coredumping.
2061 * Makefile.dist: tell TeX where to find texinfo.
2063 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2065 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
2066 the new target "rdl-apps.texinfo" which captures the Makefile
2067 variable that records where to find the Readline libraries.
2069 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
2071 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
2072 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
2073 * defs.h (const, volatile): Only define if not already defined.
2074 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
2076 * README: Update for release 3.95.
2077 * config.gdb: Don't create readline dir in subdir builds.
2078 * main.c: Include with "..." form for non-system include files,
2079 so "gcc -MM" for "make depend" works.
2080 Include readline files with "...h" rather than <readline/...h>.
2081 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
2083 * coffread.c: Undo minor damage done by Rich Pixley. Use
2084 different internal and external representations of COFF
2085 data structures. Use new BFD routines for swapping them in and
2087 * symfile.c (free_named_symtabs): Avoid freeing file names that
2088 are null or empty. Old i960 tools seem to produce files that
2089 claim to have empty names, causing each successive file read
2090 to blow away the previous one.
2091 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
2092 Move deferred_stores to top of file, but don't separate its
2093 #define's from its variable. Add commentary.
2094 * Makefile.dist: Fix Rich damage; undo "configure" changes in
2095 favor of keeping the (working) config.gdb. Move readline
2098 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
2100 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
2102 * infptrace.c (fetch_registers): no result, since now void.
2103 * tconfig/news: target depends on m68k-tdep too.
2105 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2107 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
2110 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
2111 applied various small fixes due to or inspired by RMS comments
2113 * doc/gdb.texinfo: finished using all RMS comments, save those for
2114 appendices on readline and cmd history (which are in other source
2117 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2119 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
2120 chapter 9; (2) documented 'break' command's menu mode for
2121 overloaded names, in response to hgs problem report C++ p-31
2123 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2125 * doc/gdb.texinfo: (1) better introductory example; (2) more
2126 consistent use of @code, @samp, @file, @kbd throughout; small
2127 cleanups to first three nodes; (3) new "Contributors" node;
2128 (4) Appendix, Renamed Commands; (5) divert specialized startup
2129 instructions to "Targets" chapter for generic manuals, while
2130 leaving them up front for manuals specific to specialized
2131 environments; (6) apply fixes from RMS comments through chapter 4.
2133 * pretex.m4: modify explanatory text slightly (and redefine
2134 "regexp") to keep GNU m4 from complaining. (It still crashes
2135 later, but one step at a time...)
2137 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
2139 * readline/readline.c (update_line): Avoid dereferencing a pointer
2140 before comparing it to its bounds. Saber caught this.
2141 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
2142 and only set PC if tgetstr returned non-null. Saber caught this.
2144 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2146 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
2147 stuff for config manual) here where it counts; updated
2148 to use new subdir structure (gdb/doc/).
2150 * Makefile: generated from above via
2154 * gdbint.texinfo: added instructions on generating gdb.info* files
2155 locally for release. These are ordinary info
2156 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
2157 Makefile)---but due to use of texinfo 2, can't count on makeinfo
2158 to generate these, so we distribute them already formatted.
2160 * gdb.texinfo: included full Info node and menu crud (as generated
2161 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
2163 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
2164 put in comments-for-future gdb.info target (one day makeinfo will
2167 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2169 * gdb.texinfo: Updated to include new or old undocumented
2170 commands, at least the following (perhaps some others I forgot to
2171 record): info f, info float, info path, info program, info s, info
2172 set, info source, info terminal, info types, info user, set/show
2174 Also covered all recent GDB command renames for v4.
2176 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2178 * mipsread.c: Rather than keeping count of how many symtabs
2179 and psymtabs we have, for sorting purposes, count them when
2180 we need to sort. This fixes bug in rereading of symbol tables.
2182 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2184 * infcmd.c: renamed "info path" to "show paths"

2199 symtab.h, target.c, target.h: Lint.
2200 * core.c: setup and select frame after reading shared libs,
2201 else reading shared libs will clobber them. Lint.
2202 * utils.c (error): Force out any buffered wrap text.
2204 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2206 * remote.c: Remove decls of memory_insert_breakpoint
2207 and memory_remove_breakpoint, no longer used. (Suggestion of
2210 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
2211 to make it easier to interface to "configure"'d libraries.
2213 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
2215 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
2216 aliases for set/show print.

2346 Remove from_tty arg to mod_path.
2347 Put symfile_bfd in {coff,dbx}read.c not symfile.h.

2423 rather than smash_to_method_type.
2424 symtab.c, symtab.h (allocate_stub_method): New function.
2425 dbxread.c (read_type): If we get "##", don't lookup_function_type
2426 and start clobbering it; allocate_stub_method instead.

2820 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
2821 (set_section_command): New command ("section xxx yyy" -- should
2822 be renamed to "set section xxx yyy" FIXME) which sets the
2823 base address of a section of the exec file, overriding the
2824 virtual address that BFD reports.
2826 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2828 * exec.c: Add add_syms_addr_command to exec_ops, so you can

2833 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
2834 for printing the float info is host-dependent, not
2835 target-dependent. FIXME.
2836 * i386-pinsn.c: Move #includes to top, remove useless ones.
2837 * i386-tdep.c: Don't bother including <.../reg.h> since we

2849 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
2850 * expprint.c (print_subexp): Avoid switch fallthru on

2852 * frame.h: Fix typo.
2853 * inflow.c (kill_command): After killing inferior, print our
2854 current frame in the core file, if we have one.

2884 * dbxread.c (really_free_pendings): Clear file_symbols
2885 and global_symbols after freeing them; otherwise, running
2886 this function twice (if it appears twice on the cleanup
2887 chain), we try to free things twice.
2889 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
2890 based on text_addr (the address of text in core), not on addr (the
2891 offset between text in the .o file and in core). This change
2892 is from Peter Schauer.
2894 * main.c: Define ALL_CLEANUPS as a cast of zero.
2895 (return_to_top_level): Use it.
2896 (main): Do all cleanups after each command run as part
2897 of the gdb startup sequence. Also do all cleanups before
2898 entering the command loop, and every time we exit the command
2899 loop and reenter. Before, the cleanups from the startup sequence
2900 were being left undone until the first error!
2901 (command_loop): Rename do_nothing cleanup to command_loop_marker
2902 so we can see it easily when examining the cleanup chain.
2903 (init_signals): Add another do_nothing for signal handling.
2904 (quit_command): Only try to kill target if it has execution.
2905 Problems in the target stack got us into a state where
2906 inferior_pid was nonzero but none of the targets had execution.
2907 In this state you couldn't exit gdb.
2909 * dbxread.c: Two changes from Peter Schauer.
2910 (echo_command): Fflush output after an echo command.
2911 (show_history): Pass all args to cmd_show_list.
2913 * utils.c (init_malloc): Call mtrace to turn on tracing
2914 if the environment variable MALLOC_TRACE is set to a file name.
2915 * mtrace.c: Add source file which provides a log of every malloc,
2916 free, and realloc to a trace file.
2917 * mtrace.awk: Add source file which analyzes the trace file.
2918 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
2919 (VERSION): Roll to 3.94.3.
2921 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
2922 (check_duplicates): Don't bother with watchpoints.
2923 (set_raw_breakpoint): Comment about danger of this routine.
2924 (watch_command): Parse and eval all args before calling
2927 * solib.c (find_solib): Avoid error in referencing memory to
2928 see if any more shared libraries have been added. This is
2929 particularly useful if the target has terminated. Bug reported
2932 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
2933 in bringing up 3.94.2 on the Sun-3.
2935 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
2936 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
2937 expression (in scope) before reenabling watchpoint.
2938 * signame.c (init_sigs): Add missing declaration of i, fix
2939 sys_siglist declaration.
2940 * source.c (list_command): Fixed range computation to use
2942 * stack.c (backtrace_command): Do not allow command if target has
2943 no stack, print informative error message.
2944 * target.c (target_command): Do not write into command line
2945 because this fails if the target command is used in a user defined
2946 command. [This change was enhanced by gnu to support any-
2947 unique-prefix matching on target names.]
2948 * valops.c (value_struct_elt): Avoid infinite loop on an
2949 erroneous attempt to print the member of function (try p main.p).
2951 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
2953 * expread.y (name_no_typename): Avoid reduce/reduce errors
2954 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
2955 Since the GDB parser really doesn't use name_no_typename in a
2956 name-only context, the parser can't tell the diff between
2957 names and numbers here. Avoid allowing a name_no_typename
2958 to be a NAME_OR_*INT to resolve the conflict.
2960 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2962 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
2964 * valprint.c (val_print_fields): bitfield printing didn't handle
2965 byte order. Indirect through a few more fns to cope.
2967 * values.c (modify_field): also cope with byte order.
2969 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2971 Cleanup for release 3.94.2:
2973 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
2974 include files. Roll version to 3.94.2.
2976 * coffread.c (init_stringtab): Read length into unsigned char
2977 array before swapping; don't assume 32-bit longs.
2979 * target.c (target_info): Don't bother with get_sym_file, just use
2980 the symfile global variable.
2981 * symtab.h, symfile.c (get_sym_file): Delete it.
2983 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
2984 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
2985 (read_type): Replace one more error() with complain().
2987 * mipsread.c (parse_partial_symbols): Replace printf with complain.
2989 * i960-tdep.c: Fix copyright attribution.
2991 * config.gdb: Quote all backquotes in doublequotes. You can
2992 quote me on that. BSD 4.4 shell found this one.
2994 * infptrace.c (throughout): The third argument to ptrace is an
2997 * infrun.c (wait_for_inferior): When program has terminated, we
2998 have to call target_terminal_ours before we pop that target off
2999 the stack (e.g. before a call to target_kill or
3000 target_mourn_inferior). This fixes problem where a program
3001 terminates, then GDB stops for (tty output) and you have to type
3002 "fg" to the shell to resume it. FIXME: This code for what to
3003 do after termination really should be in normal_stop instead.
3005 * gdbcore.h (read_memory_check): Change declaration; it changed
3008 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
3009 4.4 prereleases, this avoids a bug in their sgtty compatability
3011 * remote.c: Use terminal.h rather than hand-rolling the same.
3013 * signame.c, signame.h (psignal): Arg is unsigned, not int.
3014 * utils.c (strsave, strstr): Fix arg types.
3015 * valprint.c (val_print): lint
3017 MIPS symbol table support from Per Bothner:
3019 * symfile.c (symtab_fns): Remove initializer table that needs to
3020 be hacked for each new symbol file format supported.
3021 (add_symtab_fns): New function, chains symbol table
3022 handlers into the global list.
3023 (symfile_init): Search this list.
3024 * symfile.h: Add next pointer, declare add_symtab_fns.
3025 * coffread.c (_initialize_coffread): Call add_symtab_fns.
3026 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
3028 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
3029 symbol *). Thus, we no longer need the hack to trash
3030 pst->filename. Good, since that hack confused code in symfile.c!
3032 (reorder_symtabs, destroy_all_symtabs): Removed static
3033 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
3034 Instead, the latter now uses a temporary array (stack-allocated
3035 from an obstack, and then freed).
3037 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
3038 haven't been set in the outermost stBlock of a procedure. This was
3039 a problem with f77 binaries on Ultrix 4.?.
3041 (new_symtab, new_symbol, new_type): Continue changing code to use
3042 obstacks more and otherwise conform to dbxread internal style.
3043 Made the free_code of symtabs be free_linetable (as in dbxread)
3044 instead of free_contents. This implies memory leaks when reading
3045 a new symbol table, until the conversion is finished. Did change
3046 (struct symbol) and (struct type) to be allocated on the
3047 symbol_obstack. Blocks and blockvectors are among the things
3050 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
3051 tested much, but it solved one problem (reported by Meissner), and
3052 cleans up some other things. The problem happened when an
3053 included file contains actual code (functions) and not just
3054 definitions. The mips coff is a little inconvenient there, since
3055 it may cause a procedure to be mapped to the wrong psymtab.
3057 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
3058 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
3059 this will need work for the new core paradigm.
3061 Opcode patches from the net:
3063 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
3064 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
3065 missing altogether - they are added here. From Bruce Bauman.
3066 * mips-opcode.h: The low mask for C0 instructions was too small.
3067 From Garrett Lau. I modified the fix to check the entire 32-bit
3070 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
3073 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3075 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
3077 * dbxread.c (read_type): Pointer subtraction (value_sub in
3078 valarith.c) sometimes failed because the types of the
3079 pointers being subtracted were not identical.
3080 These differed because dbxread.c was allocating pointer types
3081 using dbx_alloc_type+smash_to_pointer_type instead of
3082 lookup_pointer_type. I failed to find a justification for the
3083 former, so I changed it to use the latter. Similarly, I
3084 replaced smash_to_function_type by lookup_function_type,
3085 and smash_to_reference_type by lookup_reference_type.
3087 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
3088 _initialize_mipsread): corresponding changes.
3090 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
3092 * source.c (mod_path): Do tilde_expand on each component of the path,
3093 rather than on the (list of) paths as a whole.
3094 (print_source_lines): Set first_line_listed in addition to
3095 current_source_symtab and current_source_line. If the source was
3096 not findable, after a "dir" command to fix the problem,
3097 a "list" would get the wrong lines.
3099 While I was there... (gnu):
3101 * dbxread.c (read_type): Change error to complaint.
3103 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3105 First attempt at detailed understanding of symbol table memory alloc.
3107 * dbxread.c (dbx_symfile_read): Free our string table if we
3108 aren't the mainline. Free the "info" struct since we're done with
3110 (init_psymbol_list): Free any previously allocated psymbol lists.
3111 (): FIXME: Should realloc-down the psymbol lists when done reading
3112 the main symbol file?
3114 * symmisc.c (free_symtab): Free fullname field too.
3116 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
3117 (REGISTER_ADDR): Make result type unsigned int.
3119 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
3120 define REGEX must also define REGEX1 (its dependency).
3122 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
3124 * tconfig/i960: No longer works, points you at vxworks960 or
3127 * xgdb.c, XGDB-README: Remove file. Users can get the much
3129 * Makefile.dist: Remove all trace of xgdb.
3131 * breakpoint.c (breakpoint_1): Pass demangle arg to
3132 print_address_symbolic.
3133 (clear_breakpoints): Remove unused function.
3134 (breakpoint_re_set_one): Guts of breakpoint_re_set.
3135 (breakpoint_re_set): Use catch_errors to do them all anyway.
3137 * gdb-int.texinfo (Host versus Target): Add section on what is
3138 a "host" feature versus what is a "target" feature.
3140 * infcmd.c (path_command, path_info): Handle the PATH variable
3141 (object search path) as conveniently as the source search path.
3142 * environ.c (set_in_environ): Set some vars in GDB's environment,
3143 in addition to the child's. PATH, G960BASE, G960BIN for starters.
3144 * source.c (mod_path): New function, from guts of
3145 directory_command, modifies a path. Used by path_command.
3146 (directory_command): Call it.
3147 * defs.h (strsave): Declare.
3149 * utils.c (sevenbit_strings): Add new printing option.
3150 (printchar): Use it.
3151 (strsave): Provide this handy helper routine.
3152 (set_width_command): Rename set_screen_width_command.
3153 (_initialize_utils): "set screen-width" => "set width";
3154 "set screen-height" => "set height"; add sevenbit-strings.
3156 * infcmd.c (do_registers_info): Print floating point registers
3157 in raw hex as well as float format, regardless of whether it is
3158 a "virtual" convertible register.
3159 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
3160 regs as a double, just in case it's being used that way.
3161 * values.c (unpack_long): Comment on array/function coercion.
3162 (unpack_double): Argument is in target byte order now. For
3163 integer arguments, just call unpack_long and float the result.
3164 * m68k-tdep.c: include defs.h for "const" handling.
3165 * remote-nindy.c: Use ieee-float stuff.
3166 (nindy_fetch_registers): Unpack double regs to host double, then
3168 (nindy_store_registers): Pack extendeds to host double, flip
3169 around by misusing unpack_double, send as target double.
3171 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
3172 zero, as when stopped at the first instruction of a process.
3174 * blockframe.c: Fix filename in comment (param.h => tm.h).
3175 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
3176 * tm-68k.h: Fix typos.
3178 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
3180 Changes from a bringup on the DEC Vax under Ultrix 4.0.
3182 * coredep.c (fetch_core_registers): Pass end-address of register
3183 section to register_addr as expected. Don't call supply_register
3184 if we'd just pass it garbage.
3186 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
3188 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
3190 * target.c (push_target, target_info): Cast enums to int for < or
3193 * stack.c (print_frame_info): Identify source file & line
3194 even if we can't print it.
3196 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
3198 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
3200 Clean up IEEE floating point support.
3202 * ieee-float.h: New file.
3203 * ieee-float.c: Write real routines to convert between host
3204 doubles and various target IEEE extendeds.
3205 * m68k-xdep.c: Eliminate assembler code for extended floats.
3206 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
3207 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
3208 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
3209 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
3210 double_to_ieee_extended.
3211 * i960-tdep.c: Define ext_format_i960.
3212 * m68k-tdep.c: Define ext_format_68881.
3213 * sparc-tdep.c: Define ext_format_sparc, though unused.
3214 * Makefile.dist (HFILES): Add ieee-float.h.
3215 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
3218 Obsolete the "coffstrip" program in favor of using BFD's strip.
3220 * nindy-share/coffstrip.c: Remove file.
3221 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
3222 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
3223 * tconfig/nindy960: Remove reference to coffstrip.o.
3225 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
3227 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3229 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
3230 * dbxread.c: Remove static symfile_bfd.
3231 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
3233 * inftarg.c (child_detach): Pop the child_ops vector if the
3234 detach is successful.
3235 * remote-nindy.c (nindy_create_inferior): Don't push a new
3236 nindy_ops since nindy uses the same one for execution and memory
3238 * core.c (core_ops): Use child_attach and child_create_inferior
3239 rather than default attach and create_inferior functions.
3241 Handle floating point registers in core files.
3243 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
3244 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
3245 This version untested since BFD doesn't yet support sun3 core
3247 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
3248 conventions. Fix comments and style. This version has not
3249 been compiled yet, since we have no HP inhouse.
3250 * core.c (get_core_registers): Look for two sections, ".reg"
3251 and ".reg2", and pass both to fetch_core_registers sequentially.
3253 Revise directory path yet again.
3255 * source.c (forget_cached_source_info): Not static any more.
3256 (init_source_path): New default source path is "$cdir:$cwd".
3257 (dir_command): Handle variable arguments ($cdir, $cwd).
3258 (source_info): Print "Compilation directory" rather than
3259 "Originally compiled in" to remind people of $cdir.
3260 (openp): If the path contains $cwd, use current directory.
3261 (open_source_file): If compilation directory is known, replace
3262 first $cdir in path with the compilation directory.
3263 (print_source_lines): Even if we can't print the lines, set the
3264 current symtab and line for future commands like "info source" or
3265 "breakpoint". Also, error message now contains the file name,
3266 line number, and file access error message.
3267 (_initialize_source): Fix help text to describe changes.
3268 * main.c (cd_command): Forget cached source info when we chdir.
3269 * utils.c (strstr): Add simple implementation.
3271 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
3273 * coffread.c (read_one_sym, init_linetable, init_stringtab):
3274 Byte-swap COFF symbol tables if necessary when reading them in.
3275 Use complain() to replace error message in one spot. Needs
3276 corresponding change in bfd/coff-code.h to make some symbol
3277 swapping routines non-static.
3279 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3281 Merge changes from Eirik Fuller, for UTek.
3283 * defs.h (errno): Add declaration.
3284 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
3285 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
3286 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
3287 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
3288 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
3289 declarations of errno.
3291 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
3293 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
3294 <rpc/rpc.h> and <rpc/types.h>.
3296 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
3298 * i960-tdep.c (examine_prologue): Add new argument limit,
3299 which stops the scan at the end of the prologue, or at the PC.
3300 This fixes a problem where it walks down into the code for the
3301 user's statements if that code looks like function prologues.
3302 Mark Fox and I have been bouncing this code back and forth, making
3303 small changes to it. Callers changed to match.
3305 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
3307 Cleanup for gdb-3.94 release final:
3309 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
3310 the .c files from vx-share and nindy-share, from the various
3311 macros, since they are not found via ALLDEPFILES.
3312 (SFILES): Add tm-i960.h.
3313 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
3314 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
3316 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
3317 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
3319 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
3321 * am29k-tdep.c: Add contribution line.
3322 (examine_prologue): Cache information about function prologues in
3323 the misc-function-vector to avoid lots of references over the
3324 serial line while examining instructions.
3326 * core.c (core_close): New function made from cleanup_core.
3328 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
3329 remote-vx.c, remote.c, target.c, target.h,
3330 Update target_ops vector to add attach, close, and load entries.
3331 Use add_syms_addr_command, not add_file_addr_command, for
3332 add_file. Break out close routine from existing code.
3334 * dbxread.c (really_free_pendings): Don't free pending_blocks;
3335 they are in an obstack.
3336 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
3338 (define_symbol): Add symbol type parameter; change callers;
3339 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
3340 it to influence the symbol class on the i960.
3341 (define_symbol): Swap LOC_CONST's into target byte order.
3343 * exec.c (exec_close): New function.
3344 (exec_file_command): Call it.
3346 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
3347 Fix byte order of frame pointer.
3348 (read_var_value): Result of 0 if var's value can't be found,
3349 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
3350 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
3351 (locate_var_value): Use read_var_value and use its lazy address
3352 as the location of the var's value. Lint.
3354 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
3357 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
3358 obsolete Intel versions in favor of vxgdb versions.
3359 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
3360 code dealing with byte order of values, which Intel did in host byte
3361 order rather than gdb-4's target byte order.
3362 (i960_frame_chain_valid): Move to nindy-tdep.c.
3363 (examine_prologue, skip_prologue, frame_find_saved_regs,
3364 frame_args_address, leafproc_return, saved_pc_after_call,
3365 pop_frame): Add vxgdb versions from Mark Fox.
3366 (examine_prologue, frame_struct_result_address): Add code
3367 to deal with the saved value of G13 (struct return address
3369 (frame_args_address): Modify Mark's version to prefer the
3370 saved value over the current value in the topmost frame.
3371 Cache result in the frame info to avoid performance hair in
3373 (print_fault): Add gdb960 code for printing faults.
3374 (_initialize_i960): Actually call check_host.
3376 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
3377 add stub routines. FIXME, these currently just return zero!
3379 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
3380 (attach_command): Call target_attach, not target_open, now.
3382 * infrun.c (normal_stop): Make global, not static, for vx_attach.
3383 (child_attach): Rename from child_open.
3384 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
3385 don't confuse it with a zero step_resume_break_address.
3387 * inftarg.c (child_detach): Eliminate inferior_pid test.
3388 (child_files_info): Clean up message a bit.
3389 (child_ops): Use child_attach, not child_open, to attach.
3391 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
3392 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
3393 findvar.c to here, since it depends on the contents of the
3394 shadow_contents of breakpoints, but keep if #if 0 since it is
3397 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
3400 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
3401 (ptype_command, display_command): Eliminate have_inferior_p and
3402 have_core_file_p in favor of target_has_stack or
3403 target_has_execution.
3404 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
3405 code for actually finding the values of arguments, though we still
3406 keep track of the maximum stack offset for use in printing unnamed
3407 arguments. Handle missing FRAME_ARGS_ADDRESS.
3409 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
3410 (struct nindy_regs): Define registers passed to/from nindy.
3411 (nindy_fetch_registers, nindy_store-registers): Translate between
3412 nindy and GDB formats for the registers.
3413 (dcache_init): Statically allocate the cache, since it was being
3414 allocated by a malloc that was never freed anyway.
3415 (nindy_create_inferior): Error, not core dump, if no exec file.
3416 (nindy_before_main_loop): Use target_load, not target_add_file.
3418 * remote-vx.c (net_load): Specify large timeout for load
3419 requests. Allow user to break out with INTERRUPT.
3420 (net_break): Remove useless code, clean up. Change callers.
3421 (parse-args, skip_white_space, find_white_space): Clean up arg
3422 parsing to cope with quoted strings.
3423 (net_wait, net_quit): Never call error, just return status.
3424 (vx_read_register, vx_write_register): Cleanup status checking.
3425 #ifdef the code based on which CPU we are using (960 or 68k),
3426 FIXME, this should be completely general but it isn't yet.
3427 (vx_xfer_memory, vx_resume): Cleanup status checking.
3428 (vx_run_files_info): Improve message.
3429 (vx_load_command): Renamed from vx_add_file_command. Allow load
3431 (net_ptrace): Remove unused routine.
3432 (vx_wait): Adopt code from vxgdb960 to cope with broken
3433 connections to target machine and prompt to disconnect. Remove
3434 debug printouts. Map some EVENT_'s to SIGnals.
3435 (add_symbol_stub, vx_open): Print names of object files we found,
3436 and "ok" if we read their symbols OK. Clarify output in general.
3437 (vx_attach, vx_detach, vx_kill): Add these commands.
3438 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
3439 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
3440 "info files" output, and create_inferior, since we already have
3443 * stack.c (frame_info): Replace Frame_unknown with 0.
3444 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
3445 (return_command): Pop until the PC matches as well as the FP,
3446 so it works even if the FP is shared with another function,
3447 as in "frameless" or "leaf" procedures.
3449 * symfile.c (load_command): renamed from add_file_target_command.
3450 (add_syms_addr_command): renamed from add_file_addr_command.
3451 (add_syms_command): Stub to call target_add_syms.
3452 (_initialize_symfile): Change command names and descriptions,
3453 add-file => add-syms, and load from alias to its own command.
3455 * target.c (kill_or_be_killed, maybe_kill_then_attach,
3456 maybe_kill_then_create_inferior): Default for attempts to start
3457 a process, if one is already running, is to ask about killing
3458 it and retry if yes.
3459 (upstack_create_inferior): #if-0 it, strata obsolete it.
3460 (push_target, unpush_target, pop_target): to_close() a target
3461 before unstacking it.
3462 (target_info): Renamed from target_files_info.
3463 (_initialize_targets): Rename "i files" as "i target", accessible
3466 * target.h: Improve comments about the target_ vectored routines.
3468 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
3469 Convert commenting style to standard GNU style.
3470 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
3471 (SKIP_PROLOGUE): No longer a no-op.
3472 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
3473 (*_REGNUM): Sort register numbers.
3474 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
3475 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
3476 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
3477 are now 10 byte extendeds, not 8 byte doubles.
3478 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
3479 for nindy versus vxworks targets. FIXME, this should possibly go
3480 in the target vector.
3481 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
3482 frame_saved_regs and arg pointer with each frame.
3483 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
3484 (FRAME_ARGS_ADDRESS): Use cached result.
3485 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
3486 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
3487 (PRINT_RAMDON_SIGNAL): Call print_fault.
3488 (POP_FRAME): Now works.
3490 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
3491 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
3492 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
3493 (ADDITIONAL_OPTION_HANDLER): use target_load, not
3496 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
3497 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
3499 * valarith.c (value_subscripted_rvalue): Avoid handling
3500 floats and doubles specially; it gave alignment errors. Lint.
3502 * valops.c (value_of_variable, value_of_this): Error if unknown
3505 * valprint.c (print_floating): Bcopy rather than pointer-deref,
3506 to avoid alignment problems.
3507 (value_print): Handle unknown value address.
3508 (cplus_val_print): Two args are ignored; remove them. Change caller.
3509 (val_print): Use unpack_long rather than pointer-deref.
3512 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
3513 to avoid alignment problems.
3514 (value_being_returned): Error if return value unknown.
3515 (set_return_value): Add bogosity warning, FIXME. *
3517 * TODO: A woman's work is never done.
3519 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
3520 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
3521 Add ieee-float.o to OBS.
3522 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
3523 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
3524 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
3526 Changes to generalize the VxWorks RPC protocol slightly, to handle
3527 i960 as well as 68000.
3529 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
3530 * vx-share/reg.h: Produce i960 regs #ifdef I80960
3531 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
3532 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
3533 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
3534 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
3535 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
3536 so they will move in target byte order rather than network
3537 byte order (happens to be the same).
3539 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
3541 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
3543 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
3546 Add contribution lines to various files, showing where they
3549 * breakpoint.c (break_insn, check_break_insn_size,
3550 read_memory_nobpt): Remove to mem-break.c.
3552 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
3555 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
3556 entry has bad register number. This change is not
3557 tested in this release, FIXME.
3559 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
3562 * value.h: Force value's contents field to be aligned to hold
3563 at least a double or a long long (if supported). This avoids
3564 doing bcopy's in and out of the contents field.
3566 (step_1): Avoid coredump under obscure circumstances when we
3569 * symtab.h (misc_info): Add field to misc function vector for
3570 any kind of cached information the target code desires. AMD
3571 29000 uses this to avoid repeating examine_function_prologue's.
3573 * coffread.c: Lint. Remove static symfile, read_section_header.
3574 core.c (have_core_file_p): Lint: remove.
3575 expprint.c (print_subexp): Lint.
3576 infptrace.c, valops.c, valprint.c: lint.
3578 Roll in changes from vxgdb-5.0.1:
3580 * symtab.h: Comment byte order of each address class. Add
3581 LOC_LOCAL_ARG for frame-relative args (960).
3582 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
3583 symtab.c, symmisc.c: ditto.
3585 * infrun.c (init_wait_for_inferior): Clear stop_signal.
3587 * remote.c (remote_resume): Error if resume with a signal.
3589 * symfile.c (prim_record_misc_function): Clear misc_info.
3590 (fill_in_vptr_fieldno): Check stub type of arg.
3592 * valops.c (value_cast): Avoid looking up names of types whose
3593 name we don't know, to prevent coredump. Sun CC produces typedef
3594 rtx and the name of *rtx is zero...
3596 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3598 Roll in changes from final AMD 29000 port (Tiemann).
3600 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
3601 for ../include/a.out.encap.h. This might not work now that BFD
3602 is separately compiled. Instead, BFD support for encap will have
3603 to translate machine type 29k into the right COFF_MAGIC.
3605 * infcmd.c: Remove references to inferior_pid that aren't used
3606 in actual ptrace calls; use target_has_execution, etc.
3607 (have_inferior_p): Remove function.
3608 (program_info): Print target info rather than "process number";
3609 avoid gratuitous messages unless from_tty.
3610 (run_stack_dummy, finish_command): Set proceed_to_finish.
3611 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
3612 main.c: Lint. Lose have_inferior_p().
3613 inferior.h (have_inferior_p): Remove, lint.
3614 (proceed_to_finish): Add flag to ask that all regs be saved
3615 by normal_stop, for the few commands that need it, speeding up
3616 serial I/O. Add comments to stop_registers.
3618 * remote-eb.c: Remove newline from breakpoint message we grep
3619 for. Never time out when running the user program.
3623 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3625 Roll in changes from vxgdb-5.0.1:
3627 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
3628 symbol in its raw form, we are processing an unlinked ".o" file.
3629 See if the target environment has assigned it an address, using
3630 target_lookup_symbol (VxWorks does), and enter it into the symtab
3633 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
3634 68k versions for a simpler version that assumes zero FP at bottom.
3635 Fixes bug of truncated stack reports.
3637 * target.h (target_lookup_symbol): Define this routine's args
3638 and result, finally.
3640 * target.c (nosymbol): Default routine for target_lookup_symbol.
3641 (target_default): Default lookup_symbol and call_function too.
3642 (files_info): Only print has_all_memory warning if a non-dummy
3645 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
3646 vx_convert_from_virtual): If target does not have floating point,
3647 zero register "values", and avoid doing cross-net conversions.
3648 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
3649 (vx_open): Rearrange code that attaches to target and reads
3650 symbols for all loaded modules, to work if some of the modules
3651 are not accessible. Add symbol_stub() and add_symbol_stub()
3652 as callbacks from catch_errors(). Allow connect attempt to be
3653 interrupted painlessly with ^C (FIXME, there are still some bugs
3654 if the interrupt happens during symbol reading.). Print
3655 final message with puts_filtered, since symbol messages are
3660 * main.c (catch_errors): Only print errstring if non-null.
3661 (command_loop): Avoid an ioctl per command to test ISATTY.
3663 * remote-vx.c (net_load): make static; avoid sophomoric msg.
3664 (vx_xfer_memory): Return correct result!
3665 (vx_files_info): Indicate whether target has float or not.
3666 (vx_lookup_symbol): Complain, not error, if target gone.
3667 (vx_open): Print "Connected" msg before disabling immediate-quit.
3668 [FIXME: lookup_symbol and vx_open changes need testing.]
3670 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
3671 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
3672 contributor lines and update copyrights to 1991.
3674 Changes from an attempted H-PUX host port:
3676 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
3677 defines PT_ATTACH and PT_DETACH but not PT_KILL.
3678 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
3679 * remote-vx.c: include <sys/time.h> for HPUX.
3680 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
3681 "core_file_command" routine to BFD regime. May not work yet.
3683 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
3685 * xgdb.c: Replace X10 version with some VJ version.
3686 (FIXME: Its copyright assignment is not on record.)
3687 * xgdb.c: Update include files to X11R4 (Xaw crud).
3688 (xgdb_display_source, create_text_widget): fix call to
3689 get_filename_and_charpos. Rewack source window stuff for X11R4
3690 (gleaned from include files, and "nm's" of binary libraries, since
3691 I had no doc available).
3692 (append_selection, append_selection_word): Disable with FIXME
3693 since R4 changed interface here.
3694 (create_buttons): Add back the old set of buttons.
3695 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
3697 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
3698 Roll VERSION to 3.94 (not yet final though).
3700 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3702 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
3703 obstack_int_grow, obstack_int_grow_fast): Eliminate
3704 cast on left of assignment, which gives MIPS cc fits and is
3707 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
3708 F_ALIAS. Use printf, not fprintf, when not passing a file
3710 (compare_opcodes): Check that identical instructions have
3711 identical opcodes, complain otherwise.
3713 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
3714 was reported by Roland McGrath.
3715 (unimp): Only match if exactly zero instruction. (Roland)
3716 (branches and traps): Generate all variations of these
3717 instructions with macros, based on a single call that defines
3718 each condition name and its binary representation.
3719 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
3721 * valprint.c (val_print_fields): Take, and use, format parameter.
3722 This means that "p/x struct" again prints the elements in the
3723 desired format. Changed callers.
3725 * stack.c (frame_info): Use filtered output, and indicate wrap
3726 points. Remove kludgy formatting designed to avoid line wrap.
3728 * utils.c (wrap_here): If the line is already full (because
3729 we had printed a long indent or long wrapped string), do an
3730 immediate newline-and-indent.
3732 * m68k-pinsn.c (print_insn_arg): Bugfix from
3733 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
3734 instruction is incorrectly disassembled as bkpt #8.
3736 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
3737 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
3738 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
3739 and then will dump core (sometimes). I traced it back to an
3740 uninitialized symfile_name in psymtab_to_symtab.
3741 (const_vol_complaint): Add quotes to message.
3742 (define_symbol): Only believe line number if gcc_compiled.
3743 Avoid allocating symbol if we will not return it.
3745 Add target strata support so that newly established targets go
3746 into their right place in the target stack (e.g. a new exec file
3747 doesn't wipe out the ability to access the running process).
3749 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
3750 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
3751 and initialize it properly in all the targets.
3753 * target.h: Document strata. Change return type of push_target.
3755 * target.c (nomemory): new function for dummy memory access.
3756 (tcomplain): Rename complain, now also used in symfile.c.
3757 (push_target): Push targets within strata. New return value shows
3758 whether new target is on top of stack or not. Always keep dummy
3760 (target_files_info): Ignore dummy target.
3762 * core.c (core_open): Warn user, and skip accessing file, if the
3763 core target is not the topmost target in the stack.
3764 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
3767 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
3768 target_ops, it doesn't belong there since we have no regs there.
3769 Change name of target from machine => memory to clarify.
3771 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
3773 * Freeze version 3.93 for release.
3775 * Makefile.dist: Handle vx-share and nindy-share subdirs
3776 properly when building gdb.tar.Z.
3778 * symtab.c: lint; add no_symtab_msg to consolidate the messages
3779 printed in various places, so I could change just one copy.
3781 * dbxread.c, coffread.c: Change references to bfd->iostream
3782 to cast to FILE *, now that BFD avoids needing types defined
3783 in other header files.
3785 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3787 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
3788 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
3789 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
3790 (actually gcc -Wall).
3792 * dbxread.c: Remove first_global_sym, last_global_sym, since
3793 they are never referenced.
3795 * defs.h (baud_rate): Declare.
3796 main.c: Define it, and add the -b option to set it.
3798 * gdb-int.texinfo: Add text on how to define a new host or target
3799 architecture, prompted by Per Bothner's questions about MIPS
3802 * gdb.texinfo: Document "complaints". Change doc of -q since
3803 gdb no longer prints the copyright and blurb if you specify a file
3804 name to be debugged (just like Emacs). Add doc for Nindy-specific
3805 command line flags for specifying target serial port and such.
3806 Update copyright to 1991.
3808 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
3809 has taken over for us the job of ripping up executable files. The
3810 crud caused Per Bothner's port to not compile.
3812 * infrun.c (normal_stop): Avoid printing "Program exited
3813 normally" if we are in batch mode. This allows a GDB which
3814 executes a program on a target system, to behave like a Unix
3815 command (input from stdin, output to stdout, no extraneous
3818 * main.c (main): Allow additional machine-dependent command line
3819 options to be specified with the ADDITIONAL_OPTIONS,
3820 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
3821 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
3822 processing to occur just before the main loop with
3823 BEFORE_MAIN_LOOP_HOOK.
3824 (main): If a "core file" argument is specified, and it is not a
3825 core file, try it as a process ID to attach.
3826 (symbol_completion_function): Attempt to cope with
3827 "show screen-" TAB, not very successfully. This needs more work,
3829 (batch_file): New function, returns whether we are reading
3830 commands from an interactive tty on stdin, or from somewhere else.
3831 Called by normal_stop since it doesn't get from_tty passed down
3832 to it like many commands do.
3834 * remote-nindy.c: Handle command line options for nindy
3836 (nindy_before_main_loop): Prompt user for tty name if they
3837 don't specify it before getting to the interactive command loop.
3839 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
3840 and -r command line options. Also add hook before main loop
3841 to make it easy to specify a tty.
3843 * TODO: More things to do, one done.
3845 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
3847 * dbxread.c: Make complaint() calls pass pointer, not struct.
3848 Add complaints about badly formatted C++ type information
3849 (const/volatile indicator, and parse errors resulting in
3850 error_type). Fix C++ virtual member fn comment.
3851 (read_struct_type): Avoid bumping pointer if we got a parse
3852 error; this prevents our walking beyond the end of a string.
3853 Terminate loop on null char as well as semicolon.
3854 (process_one_symbol): Fix the LBRAC fix so that it uses the
3855 last previous SLINE, FUN, or SO record's PC address. C++ debug
3856 symbols did not have SLINE records in a useful order compared
3857 to the LBRAC records.
3858 (define_symbol): Handle "catch" records.
3860 * symtab.c (check_stub_type): Added new complain
3861 `stub_noname_complain' and added a consistency check to
3862 keep the debugger from crashing when finishing from an
3863 exception frame. A real fix will be needed later.
3865 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
3867 * infcmd.c (attach_command): Make global.
3869 * Makefile.dist (REMOTE_OBS): Make these compile by default,
3870 but make them easy to comment out. Perhaps later they should
3871 be enabled by what CPU you configure for? FIXME.
3872 (VERSION): Roll to 3.93.
3873 (pinsn.o): Remove rule for obsolete file.
3874 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
3876 Run down a problem that manifested by printing the wrong function
3877 name in stack traces of read_ofile_symtab. Turned out that the
3878 problem was the SunOS 4.1.1 (and previous) C compiler outputs
3879 the LBRAC symbol with an address in the *data* segment, which
3880 blew our binary search through the blocks.
3882 * dbxread.c: Use the complain() facility consistently to bitch
3883 about problems in the symbol file we are reading.
3884 (finish_block): Add code to check the nesting of the blocks;
3885 complain and Procrust them to fit if wrong.
3886 (make_blockvector): Check the order of the blocks, complain
3887 [but don't cope] if wrong.
3888 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
3889 symbols to be sure their PC value is greater than the last SLINE
3890 (line number) symbol we've seen, complaining and adopting the
3891 SLINE PC value if wrong.
3893 * symfile.h (struct complaint, complaint_root, complain,
3894 clear_complaints): Add.
3895 * symfile.c (complain, complaint_root, clear_complaints): Add
3896 facility to deal with non-fatal complaints and to regularize their
3898 (symbol_file_add): Clear complaint counters to allow new complaints.
3899 (initialize_symfile): Add 'set complaints' and 'show complaints'.
3901 * dbxread.c (dbx_symfile_read): Remember the address and size
3902 of the string table for the main symbol file, so we won't read it
3904 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
3905 to avoid reading the string table yet again. Lint.
3906 (throughout): Improve filtered output, including word wrap.
3907 (read_range_type): Improve Bothner's fix to handle other types too.
3909 * utils.c: Improve line wrap implementation. Handle unlimited
3910 width by making chars_per_line unsigned.
3911 (puts_filtered): New, easy, function.
3913 * defs.h (puts_filtered): add.
3915 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
3916 call the identical sort_symtab_syms() in symfile.c instead.
3918 * expread.y: Suggest the `file' command rather than `symbol-file'.
3920 * command.h (enum var_types): Add zinteger for seroable
3922 * command.c (do_setshow_command): Handle var_zinteger. Restructure
3923 nested if's into a switch.
3925 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
3926 we did not stop because of a breakpoint (it must have been for
3927 some other reason, like a "stepi"), so don't print anything.
3929 * symtab.c: Include <sys/types.h> all the time. Now that BFD
3930 doesn't include <sys/types.h>, old SunOS's require it for
3933 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
3935 A test port of gdb-3.92.6 to the Sony NEWS.
3938 Don't normally link in remote- or vx stuff.
3939 Some of it doesn't compile, and it wastes space for 99% of the users.
3940 Remove reference to no-longer-used HAVE_VPRINTF.
3941 Fixed BFD_DEP typo to BFD_DIR.
3943 Fix cast in arg to bfd_h_getlong.
3944 Make char *prefix be const.
3945 Fix how certain range types are mapped into builtin unsigned int types.
3947 Remove 2 #includes. They cause errors (on Sony, at least),
3948 and aren't needed (they wern't in earlier versions).
3950 print_address_symbolic should never demangle labels
3951 (since it prints *assembler-level* labels).
3953 [This was superseded by the change to printcmd below.]
3956 Add some "volatile" return types to avoid warnings.
3957 If MISSING_VPRINTF add vprintf function and not just macro
3958 (since vprintf is used in printcmd.c).
3960 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
3961 (The latter isn't grokked by some PCC-based compilers.)
3963 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
3965 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
3966 * nindy-share/coffstrip.c
3967 Added some forward declarations (otherwise, gcc complains
3968 about implicit extern redefined as static).
3970 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
3972 Changes inspired by Per Bothner:
3973 * printcmd.c (print_address_symbolic): Take additional parameter
3974 specifying whether to demangle.
3975 (print_address): Pass in asm_demangle to control demangling.
3976 (print_address_demangle): New fn, takes explicit arg to control
3978 * utils.c: Add new vars demangle and asm_demangle, and let them
3980 (fputs_demangled): If !demangle, just print the argument.
3981 (fprint_symbol): If !demangle, just print raw symbol.
3982 * valprint.c (val_print): Call print_address_demangle rather than
3983 print_address, to cause demangling to depend on the global
3984 rather than assembler-level demangling setting.
3985 * WHATS.NEW, gdb.texinfo: Document.
3987 * main.c (show_command): Show all settings if no arg.
3988 (initialize_main): Make "info set" the same as naked "show".
3989 * command.c (cmd_show_list): Handle prefix commands in the
3990 list, and print the name of the setting as well as its English
3991 description and value.
3993 Allow gdb functions to specify where a line should wrap if it
3994 exceeds the size of a terminal line. Use it to make the output
3996 * utils.c (set_screen_width_command): New fn, mallocs a buffer
3997 of the right size when screen width changes.
3998 (set_screensize_command, screensize_info): Remove #if 0'd fns.
3999 (wrap_here): New fn, indicates a point in the output where we
4000 should wrap the line rather than just letting it overflow at a
4002 (fputs_filtered): Implement wrapping.
4003 (n_spaces): New fn, returns a pointer to N spaces.
4004 (print_spaces_filtered): Use n_spaces.
4005 * defs.h (n_spaces): Declare.
4006 * stack.c (print_frame_info): Wrap with 4-space indent after
4007 fn name and before filename and line number.
4008 * printcmd.c (print_frame_args): Wrap with 4-space indent
4009 before each argument name is printed.
4010 * valprint.c (value_print): Wrap with no indentation before
4012 (val_print_fields): Wrap with indentation relative to nesting
4013 level before each field name.
4014 (val_print): Wrap with nesting indentation before array elements.
4015 * command.c (do_setshow_command): Avoid extra newlines,
4016 wrap with 4-space indent around values printed, end with period.
4017 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
4019 * breakpoint.c (breakpoint_1): Implement addressprint for
4020 "info breakpoints" display. Change file name and line number
4021 format to " at file:nnn" rather than " (file line nnn)".
4022 * gdb.texinfo: Document.
4025 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4027 Frozen for gdb-3.92.6 release.
4029 README, WHATS.NEW: Update for 3.92.6 release.
4031 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
4032 coffread.o from configs since it is now built by default.
4033 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
4034 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
4035 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
4036 from configs since it is now built by default.
4038 Makefile.dist: Update for release 3.92.6. Handle files that
4039 have been moved to ../include, ../getopt, or ../bfd. Add
4040 saber.suppress and tests directory. Add config.status to
4041 the release (it will say "none").
4043 coredep.c: Minor formatting fixes.
4045 These changes were made in early December but only checked in now:
4046 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
4047 nindy-share/nindy.c: lint
4048 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
4049 register values coming back from the target; we store values
4050 in target byte order everywhere.
4052 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
4054 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
4056 * valprint.c (cplus_val_print, val_print_fields): New functions,
4057 which print C++ objects. They conspire to avoid printing a
4058 virtual base class more than once, following all the twists and
4059 turns of C++ virtual base rules.
4060 (val_print): Call the above rather than do it by hand.
4062 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
4063 symbol file, not for added files like shared libs. This really
4064 needs to be generalized to a timestamp per file.
4066 * core.c (cleanup_core): Avoid coredump if no core file.
4068 * config.gdb: Accept -host or -target in place of +host or
4071 * coffread.c (find_linenos): Avoid desupported BFD interface
4072 to line numbers. We still read them manually rather than using
4073 BFD's "generic" features.
4075 * gdbrc.tex, threecol.tex: Add GDB reference card and its
4077 Makefile.dist: Add refcard to OTHERS list for creating tar files.
4079 * Makefile.dist: Eliminate use of $< in explicit targets.
4081 * readline/Makefile: Use $< rather than $*.c, which does not
4082 include the VPATH in GNU Make.
4084 * tconfig/i960-bout, tconfig/i960-coff: These are identical
4085 copies of tconfig/i960, added for global configuration
4086 compatability. All i960 versions can read both coff and b.out.
4088 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
4089 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
4092 * TODO: Think of more things to do.
4094 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
4096 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
4097 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
4098 64-bit float conversion.
4100 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
4101 equivalent to sun?os4 so global config works.
4103 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
4105 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
4107 * main.c: Only declare linesize once; declare pagesize not at
4108 all, since it is never used.
4109 (main): Clear newly allocated line before it is used.
4111 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
4113 Further stabilization for the Intel 960.
4115 * Makefile.dist: Parameterize the location of the "include"
4116 and "bfd" directories, as well as "getopt". Add symfile.c.
4117 Link in both dbxread and coffread. Fix up "make depend" to
4118 rewack the locations of include, bfd, and getopt in its output.
4120 * README: Document moving include files, improve some of
4123 * coffread.c: Move common code out to symfile.c. Change
4124 symbol_file_command style interface to use new *_symfile_init
4125 and *_symfile_read interface under BFD. Use BFD internal
4126 info to locate line table, symbols, etc.
4128 * core.c (core_fetch_registers): Rename to get_core_registers
4129 to avoid confusion with fetch_core_registers.
4130 (register_addr): Move to coredep.c, which is already machine
4131 dependent. This leaves core.c pretty clean of dependencies.
4133 * coredep.c (register_addr): Accept this routine from core.c.
4135 * dbxread.c: Move common code (with coffread.c, etc) into new
4136 symfile.c. Each psymtab now contains a pointer to the
4137 format-dependent function that knows how to read it in. Make
4139 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
4140 (process_one_symbol): Add code to complain about a "compiler bug
4141 we muzzle here", if we actually see it.
4143 * eval.c (evaluate_subexp): Insert missing "break" statements
4144 in code that determines whether a variable is an lvalue in
4145 memory, register, or whatever. I detected this via a compiler
4146 bug in which it *almost* mashed out the whole switch statement.
4148 * gdb-int.texinfo: Add minor sections on configuring gdb for
4149 release, and about the README file.
4151 * infcmd.c (registers_info): Fix formatting somewhat. Still
4152 not as pretty as before, but it handles byte swapping.
4154 * remote-nindy.c: If data cache routines are interrupted while
4155 waiting for the remote end, be sure that any uninitialized cache
4156 blocks are on the free list, not on the valid list!
4158 * symfile.h: Flesh out this header file with all the various
4159 routines and variables that have been merged in from dbxread.c
4160 coffread.c, and symtab.c to symfile.c.
4162 * symfile.c: New file, containing code common to dbxread.c,
4163 coffread.c, and some code from symtab.c. All generic code for
4164 reading symbol files should be in here now.
4165 (unrecord_misc_function): Remove unused function.
4167 * symtab.h: Remove file-reading things to symfile.h.
4169 * symtab.c: Remove file-reading things to symfile.c.
4171 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
4172 to decode i960 fault types.
4174 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
4175 target.c: Change type of the "resume" function from int to void,
4176 since its result was never used.
4178 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
4180 * main.c: Replace "stupid" with "caution"; you now "set caution
4183 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
4185 * infcmd.c (do_registers_info): Call val_print to deal with the
4186 byte order of the registers being printed. FIXME, this makes
4187 the formatting of the output uglier.
4189 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
4190 defined, call it for signals the debugger doesn't itself use.
4191 The i960 uses this for more detailed fault information.
4193 * remote.c (remote_open): If arg is null, print help rather than
4196 * sparc-xdep.c (register_valid): Avoid declaring size, since
4197 various modules will think of various sizes depending on the
4198 architecture of their tm-file. FIXME, we need protection against
4199 actually entering one of those modules, which would clobber
4200 storage if not for the target architecture compiled into gdb.
4202 * stack.c (up_command, down_command): Always print the frame
4204 (up_silently_command, down_silently_command): New commands
4207 * i960-pinsn.c (reg), i960-tdep.c: Lint.
4209 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
4210 more parameters than it used to.
4212 * findvar.c (registers): Increase slop to 256 bytes, which should
4213 protect us against even most RISC machines with large register
4215 (locate_var_value): Move declaration inside related ifdef.
4217 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
4218 throughout, to avoid throwing away buffered input from the board.
4219 (nindy_wait): Supply_register takes addr_of_value, not value.
4220 (i960_print_fault): Renamed from i80960_fault.
4221 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
4222 (nindy_store_registers): Avoid regs_changed stuff, just stuff
4224 (nindy_create_inferior): Don't bother to write PC_REGNUM since
4225 we can set the PC in the call to proceed(). Unpush nindy_ops
4226 before pushing it on top, to avoid message to user. Eliminate
4227 commentary from Unix machines that just misleads here.
4228 (reset_command): Fix error message to suggest target command.
4230 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
4232 Release 3.92.5 as frozen.
4234 Stabilize the merged release...with help from lint, Saber C,
4237 Everywhere: Add include files needed to declare return types
4238 of functions called.
4240 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
4242 * breakpoint.h: Add undeclared breakpoint functions, and some
4243 functions for display handling since I couldn't think of a better
4246 * breakpoint.c (insert_breakpoints): Make code for disabling
4247 shared library bkpts more likely to work. It's used when we
4248 rerun a program and stop before the shared library has been
4250 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
4251 cast from pointer, so it squeezes through catch_errors.
4252 (bpstat_stop_status): Fix logic broken some time ago. We now
4253 always create a bpstat if the stop address matches a breakpoint,
4254 even if we don't stop there -- just like the old code used to do
4255 before I got my fingers into it (sigh).
4256 (breakpoint_1): Print "ignore count" after "stop only if"
4257 condition, since that's how it actually works.
4258 (mention): Handle watchpoints as well as breakpoints.
4259 (watch_command): use set_raw_breakpoint and mention to do most
4260 of the work (and initialize all the fields!). Only pass one
4261 arg to parse_c_expression, since that's all it takes.
4263 * command.c (not_just_help_class_command): Rename arg to args
4264 since we ignore "unused argument" warnings on vars named "args".
4265 inflow.c (child_terminal_info): ditto.
4266 infptrace.c (kill_inferior): ditto
4267 main.c (catch_errors, version_info, quit_command, pwd_command,
4268 source_command, dump_me_command, editing_info,
4269 set_history_size_command, set_history, show_history,
4271 stack.c (locals_info): ditto
4272 target.c (target_files_info): ditto
4273 valprint.c (set_input_radix, set_output_radix): ditto
4275 * core.c: Remove old variables for handling core and exec file
4276 sections (data_start, data_end, stack_start, stack_end,
4277 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
4278 text_end, exec_data_start, exec_data_end, text_offset,
4279 exec_data_offset, data_offset, stack_offset). They're
4280 superseded the more general build_section_table and
4282 (get_exec_file): Mention the `file' command.
4283 (read_memory_check): Rename to memory_error, and only call it
4284 in the case of an actual error.
4285 (read_memory, write_memory): call memory_error.
4286 (core_fetch_registers): Register section name is ".reg".
4288 coredep.c: Remove a bunch of crud now that all this file does
4289 is pull the registers out of a core file.
4290 (fetch_core_registers): Rewrite to actually work, I hope.
4292 dbxread.c: Use a.out.gnu.h, not system a.out, now.
4293 Replace index() with strchr(). Remove all the pre-BFD macro
4294 definitions for accessing the symbol file.
4295 (struct dbx_symfile_info): Encapsulate the information that
4296 dbx_symfile_init needs to pass to dbx_symfile_read in this
4299 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
4300 dbx_symfile_discard): Rearrange symbol file reading to divide
4301 the format-specific part from the format-independent part,
4302 leaving the format-independent part such as file name expansion
4303 and opening in symtab.c. This replaces
4304 partial_symbol_file_open and partial_symbol_file_read.
4305 Symbol_file_read, add_file, add_file_target_command,
4306 add_file_addr_command move to symtab.c. Pass an explicit
4307 "mainline" flag for when reading the main symbol table, rather
4308 than relying on the offset address to be zero or nonzero.
4310 (dbx_symfile_read): Don't allow void *'s to be printed as
4312 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
4313 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
4314 macro" debug version really work.
4315 (read_dbx_symtab): Remove unref'd parameter inclink.
4316 Avoid swapping N_SLINE symbols, for speed.
4317 Merge N_TEXT!N_EXT case with the other external symbol
4318 definitions' case. Add comments.
4319 (start_psymtab): Allocate the symfile name in the psymtab on
4320 the psymbol_obstack, rather than using the caller's storage.
4321 (end_psymtab): Only allocate a dependencies list if there are
4323 (psymtab_to_symtab_2): Use BFD when reopening file to read
4324 its symbols for real.
4325 (read_struct_type): Add FIXME comments where it needs work
4327 (read_huge_number): Add FIXME about overflows.
4328 (read_range_type): Add FIXME about comparing a long to 1<<32.
4330 * coffread.c: Minor changes to move things closer to the new
4331 regime with symtab.c and dbxread.c Major work is still needed
4334 * exec.c (exec_file_command): Remove old variables (see core.c
4336 (xfer_memory): If memory transfer is right at the end of a
4337 section, don't lose.
4339 * findvar.c (get_saved_register): If value is in a real
4340 register, LVAL is lval_register, not lval_memory.
4342 frame.h: Declare print_sel_frame and record_selected_frame.
4344 gdb-int.texinfo: New file, for GDB internals documentation.
4345 Very simple, unformatted doc of cleanups is there for now.
4347 gdbcore.h: Remove obsolete variables that described a.out
4348 section addresses and offsets. (See core.c above.)
4349 Declare fetch_core_registers and registers_fetched.
4351 getopt.c: Declare char *alloca(); even on SPARC.
4353 infcmd.c (run_command): Call target_kill rather than
4355 (step_command, next_command, stepi_command, nexti_command):
4356 Declare from_tty parameter even though we don't use it.
4357 (run_stack_dummy): argument BUFFER is a char array, not
4358 a pointer to REGISTER_TYPE.
4359 (finish_command): using_struct_return needed a value *,
4360 not a struct symbol *.
4362 * infptrace.c (child_xfer_memory): To avoid dependency on
4363 where sections are in memory, try PT_WRITE_D and if that fails,
4364 try PT_WRITE_I. Most Unixes don't care which you use.
4366 * infrun.c (step_resume_break_shadow): Change to array to
4367 match other breakpoint shadow storage.
4368 (clear_proceed_status): Pass address of bpstat to
4369 bpstat_clear, not the bpstat itself.
4370 (child_create_inferior): FIXME comment about if the child
4372 (start_inferior): Remove old function.
4373 (child_open): Use target_kill rather than kill_inferior.
4374 (wait_for_inferior): Ditto.
4375 (insert_step_breakpoint, remote_step_breakpoint): Use
4376 new step_resume_break_shadow.
4378 * inftarg.c (child_wait): If all child processes die,
4379 pretend that the one being waited for exited with signal 42.
4381 * main.c (command_line_input): When scanning for comments,
4382 don't coredump on unclosed quotes.
4383 (quit_command): Use target_kill rther than kill_inferior.
4384 (_initialize_main): Rename class_user from "user" to
4387 * printcmd.c (print_command_1): Initialize "fmt" if no format
4388 is specified by the user.
4389 (print_frame_args): Only add to args_printed if we are
4390 actually fetching args from the stack (avoiding undefined
4392 (_initialize_printcmd): Remove bogus \{ from string.
4394 * remote-eb.c (eb_open): Avoid coredump on no argument.
4396 * remote-nindy.c: Bring out of Intel environment into new
4397 target environment. Remove all conditional compilation on
4398 I80960. Massive hacking throughout.
4399 (nindy_xfer_inferior_memory): New routine stolen from
4401 (nindy_create_inferior): New routine pieced together, probably
4402 not quite working yet.
4403 (nindy_ops): New target_ops struct for nindy.
4405 * remote-vx.c: Use write_memory rather than target_write_memory
4406 to get error checking.
4407 (vx_add_file_command, vx_open): Use symbol_file_add rather than
4409 (vx_create_inferior): Use target_terminal_ours...
4411 * signame.c (_initialize_signame): Always initialize, since
4412 we need the table for things other than psignal.
4414 * solib.c (solib_add): Use symbol_file_add, not add_file.
4415 (solib_address): Return boolean result rather than struct
4416 pointer which nobody else knows the type of.
4418 * sparc-tdep.c, valops.c: Use write_memory rather than
4419 target_write_memory, to get error checking.
4421 * stack.c (locals_info, catch_info, args_info,
4422 get_selected_block, frame_command, up_command): Use
4423 target_has_stack, rather than have_inferior_p or
4426 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
4428 * symfile.h: New file, defining the interface between the
4429 generic and object-file-specific symbol reading code.
4431 * symtab.c: Move generic symbol-reading interface to symtab.c,
4432 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
4433 table to map BFD targets to symbol-reading modules in GDB.
4434 Change index to strchr.
4435 (lookup_struct_elt_type): Use error() rather than hand-made
4436 simulations thereof.
4437 (lookup_partial_symbol): Speedup slightly when length == 0.
4438 (symbol_file_add): New function.
4439 (symbol_file_command): Call it.
4440 (symfile_open, symfile_init): New function.
4441 (add_file_target_command, add_file_addr_command): moved from
4444 * target.c (target_command): use target_kill.
4446 * target.h (target_files_info): Don't declare, never called
4449 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
4450 files to determine stack end address.
4452 * valarith.c (value_x_binop, value_x_unop): Change error message
4453 to be more useful. Pass proper argument to value_struct_elt.
4455 * valops.c (value_assign): FIXME comment that long long
4456 bitfields will break here.
4458 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
4459 Update `make saber_gdb' to work better.
4461 * TODO: A woman's work is never done.
4463 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
4464 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
4465 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
4466 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
4467 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
4468 valops.c, valprint.c, exec.c: Lint.
4471 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
4473 Continuing Intel 960 port merge of GDB.
4475 * Makefile.dist: Merge i960 "nindy-share" files. Rename
4476 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
4477 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
4478 Wack over "make depend" so it handles files in subdirectories
4479 vx-share, nindy-share, bfd, and in the current directory.
4481 * blockframe.c (get_prev_frame_info): Remove fatal error
4482 if stack not defined.
4484 * core.c (core_open, core_detach): New functions that handle
4485 the old "core-file" command as "target core" and "detach" instead.
4486 (core_file_command): Call them.
4487 (core_xfer_memory): Use common routine xfer_memory.
4489 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
4490 dbxread now uses bfd for everything but symbol reading itself.
4491 BFD internals are used to drag out the relevant file offsets.
4492 (partial_symbol_file_open): Change args all around for BFD.
4494 * symtab.c: Rename "value" to "val" everywhere, so we can
4496 (symbol_file_command): New command, moved from dbxread.c
4497 and coffread.c. It uses BFD to read the file, then vectors
4498 based on its type, to dbx or coff symbol readers.
4499 * symtab.h: Extern a few vars for symbol_file_command.
4501 * target.h: Breakpoint takes a char * save area, not a char **.
4503 * valprint.c (val_print): When unpacking bitfields, offset
4504 the address in gdb of the value, if it is declared with a shorter
4505 type. Remove the last "runtime kludge test" of host byte order.
4507 * utils.c: Remove old my_bfd_read routine.
4509 * stack.c (frame_info): Use target_has_stack. Print program counter
4510 register's actual name rather than "pc", since it's called the
4511 "ip" (instruction pointer) on the i960 (sigh).
4513 * target.c (target_command): Add command for selecting a target
4514 type and calling its open routine. This is used for initiating
4515 communication with a particular target, in a generic way.
4517 * tm-i960.h: Update for modern gdb. Remove semicolons from
4518 various macros. Handle reading struct return convention, and
4519 error-out attempts to return structs with the "return" command.
4520 Be sure gdb doesn't think we know how to call functions in the
4523 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
4524 to i960_xxx in lower case.
4525 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
4526 not being defined yet.
4528 * remote.c (remote_open): Call start_remote to initialize
4529 wait_for_inferior during open.
4530 (remote_xfer_inferior_memory): Return length written rather
4533 * remote-vx.c (target_command -> vx_open): Use new generic
4535 * remote-eb.c, inftarg.c, exec.c: ditto.
4537 * infrun.c: Fix comments.
4538 (attach_program -> child_open): Use new generic target command.
4539 (wait_for_inferior): Clear saved register values before target_wait,
4540 so target_wait can set some of them if convenient.
4542 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
4543 Return success indicator, not void.
4544 (child_xfer_memory): Avoid fetching initial word if we'll
4545 overwrite it anyway.
4547 * infcmd.c (attach_command): Use new generic target open routine.
4548 (_initialize_infcmd): Update doc on attach and detach commands.
4549 (do_registers_info): Merge in a byte-order problem as a FIXME
4552 * findvar.c (find_saved_register): Avoid problem in current frame.
4553 (read_relative_register): Ditto.
4554 (write_register): Convert byte order on the way out.
4556 * exec.c (file_command): Add.
4557 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
4558 (xfer_memory): Common function between core_xfer_memory and
4560 (exec_xfer_memory): Use it.
4562 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
4564 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
4565 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
4566 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
4568 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
4570 Merge Intel 960 port of gdb, continuing...
4572 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
4573 symbol_file_command): Pass from_tty arg to hush 'em up.
4575 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
4576 Add magic numbers for 960 COFF format.
4578 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
4580 Merge Intel 960 port of gdb, from Intel "1.2" release.
4582 CHANGE_LOG entries from their port, which was based on
4585 Thu Sep 6 11:02:22 PDT 1990
4586 Remove temp file if download is interrupted.
4588 Wed Aug 1 09:08:33 PDT 1990
4589 Now uses binary protocol to talk to NINDY.
4590 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
4591 Times out after 5 seconds when trying to talk to NINDY.
4593 Tue May 29 12:54:49 PDT 1990
4594 Added variable baud rate (-b switch).
4595 Source code reorganization.
4597 Thu Apr 26 11:09:55 PDT 1990
4598 More cleanup of batch mode; specifically, execute "-s", "-e", and
4599 "-se" switches as soon as they are encountered on the invocation line.
4601 Fri Apr 20 13:47:15 PDT 1990
4604 Thu Apr 19 09:54:28 PDT 1990
4605 Add 'reset' command.
4607 Wed Apr 18 09:48:07 PDT 1990
4608 After opening remote tty, wait for 1 second to go by without input
4609 from it before trying to talk to NINDY (fixes problems with the
4610 Heurikon HK80/V960E).
4612 Mon Apr 4 16:33:05 PDT 1990
4613 Some output was not being suppressed in 'batch' mode.
4615 Thu Mar 22 15:31:11 PST 1990
4616 Ask user if old symbol table should be deleted when new file is
4619 Allow user to run a program downloaded before gdb960 was brought up.
4621 Correct "exec-file" help message for i80960 context.
4623 Correct bug in calculating user space address: could occasionally
4624 corrupt user program.
4626 Make sure to zero low-order bits in rip's because of bug in 960CA
4627 A-step part: could cause operation faults when "next"ing across
4630 Correct bug that made it impossible to get source line numbers for
4631 code loaded at addresses higher than 0x7fffffff.
4633 Wed Jan 10 12:43:22 PST 1990
4634 Open remote tty for exclusive use.
4636 Fri Jan 5 12:14:42 PST 1990
4637 Correct disassembly (CA manual was right after all):
4638 opcode for sysctl is 0x659
4640 Mon Oct 23 12:03:04 PDT 1989
4641 Use G960BASE and G960BIN environment variables to find 'sx' utility.
4643 Mon Oct 16 14:15:09 PDT 1989
4644 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
4646 Mon Oct 2 15:56:31 PDT 1989
4648 Added 960CA disassembly support.
4650 To simplify maintenance:
4651 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
4653 - eliminated opcode.h: incorporates tables into i960-pinsn.c
4654 - moved 960-specific routines from i960-pinsn.c to i960-md.c
4655 - made disassembly interface identical to that in gdmp960.
4659 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
4661 * target.h: Allow targets to stack. Add target_has_memory,
4662 _registers, etc. Restructure memory access and "info files"
4663 to walk the target stack.
4664 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
4665 target.c: Change tables to match target.h.
4666 * inflow.c (child_mourn_inferior): pop child_ops.
4667 (generic_mourn_inferior): Use new has_stack flag.
4668 * infptrace.c (child_xfer_memory): New memory regime.
4669 * inftarg.c (child_files_info): New "info files" regime.
4670 * remote-eb.c: New memory regime, new info files.
4671 * remote-vx.c: New memory regime, new info files. Now use
4672 separate targets for VxWorks attachment to machine, and
4673 actually running a process under VxWorks, since one has
4674 stack & execution & regs and the other doesn't.
4675 * remote.c: New memory regime, new info files.
4676 * sparc-xdep.c (fetch_core-registers): New memory regime.
4677 * target.c: New routines and support for stacked targets,
4678 new memory regime, new info files regime.
4681 Generalize section handling for an arbitrary number of sections,
4682 including use of the new BFD (binary file) library.
4683 * gdbcore.h: Add struct section_table.
4684 * exec.c (build_section_table): Iterate all sections and
4685 record what gdb needs to know about them.
4686 (exec_command): Use it.
4687 (exec_xfer_memory): Use the table.
4688 (exec_files_info): Print the table.
4689 * core.c (core_file_command, core_xfer_memory, core_files_info):
4691 * source.c (find_source_lines): Use bfd_get_mtime.
4692 * dbxread.c: Quick changes to make it compile with new BFD.
4693 * utils.c (error): Avoid using bfd_error in generic routines.
4695 * core.c (core_fetch_registers): Get from the ".regs" section of
4697 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
4699 * inferior.h (attach_flag): Export.
4700 * infcmd.c (run_command): use new target_create_inferior.
4701 * infrun.c (child_create_inferior): Don't return result.
4702 * Makefile.dist (VERSION): 3.91.4.
4704 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
4706 * breakpoint.c (bpstat_num): Handle breakpoints which have
4707 since been deleted, such as temporary breakpoints.
4708 infcmd.c (program_info): ditto.
4710 * core.c (core_file_command): Display the frame where the core
4715 * remote-vx.c (target_command): Merge in target command from
4716 targ-vx.c. A few other cleanups.
4718 * TODO, Projects: Lots more stuff to do...
4720 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
4722 Massive changes to wall off the remote-debugging interface
4723 behind a function vector. The port to handle VxWorks targets
4724 is also part of this.
4726 All files: Replace references to renamed functions,
4727 remove references to remote_debugging, remove references to
4728 have_include_file, have_core_file in favor of target_has_stack,
4729 target_has_memory, etc.
4731 * Modularize the breakpoint interface.
4732 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
4733 a breakpoint instruction.
4734 breakpoint.c: struct breakpoint's shadow_contents now sized as
4736 (insert_breakpoints): Vector to target to install breakpoints.
4737 (remove_breakpoints): Vector to target here too.
4738 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
4739 sparc-tdep.c (single_step): Use new breakpoint interface for
4740 the single-step breakpoints.
4741 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
4742 New file, contains routines to insert and remove breakpoints by
4743 reading out the old contents and later replacing them. This is
4744 how ptrace breakpoints work, and many remote systems as well.
4746 * tm-vxworks68.h: New config file, overrides a few things for
4747 Wind River's preferences.
4749 * target.h: New file, for transfer vector used to talk to the
4750 inferior (child, attached, core, exec, remote, etc). All accesses
4751 to the thing being debugged should come through these vectors.
4752 target.c: New file, routines to handle transfer vector.
4753 (various files): Add transfer vectors XXX_ops for the various
4754 targets and pseudo-targets (core files, etc) we support.
4756 * breakpoint.c (bpstat_stop_status): Further explorations of
4757 watchpoints and why things don't work all the time.
4758 (bpstat_alloc): New fn to allocate a bpstat and chain it.
4760 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
4761 the local gdbinit if it doesn't already have it.
4763 * core.c (core_ops): add and install.
4764 Allow core debugging without exec file.
4766 * dbxread.c (free_and_init_header_files): Merge two fns.
4767 (end_symtab): Free named symbol table when a new version comes in.
4768 (read_dbx_symtab): Relocate all kinds of symbols with base
4769 address. First step toward handling different text, data, bss
4771 (add_file_addr_command): Renamed add_file_command.
4772 (add_file_command): Vector to remote handler.
4773 Add "load" as an alias for "add-file" command.
4775 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
4776 non-returning functions.
4778 * exec.c: Add exec_ops, and push it as a target when an exec
4781 * infcmd.c (run_command): Pass executable file name and arg list
4782 separately when starting an inferior. Permit "run" when no exec
4783 file is specified, for VxWorks.
4784 (detach_command): Move to child_detach in inftarg.c.
4786 * inftarg.c: New file. Unix-child-specific routines, and the
4787 child_ops structure.
4789 * inferior.h (registers): Export "registers" as the way for
4790 target dependent register handlers to find gdb's local copy of
4791 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
4792 since it is now used by places that want wait_for_inferior to
4793 handle the grunge but want to see every trap from the inferior.
4795 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
4796 Eliminate remote_debugging hooks in terminal handling.
4798 * infrun.c: Replace start_inferior with child_create_inferior.
4799 Move all the hair of Unix shells and ptrace idiosyncracies into
4800 child_create_inferior, so remote handlers don't have to deal.
4801 Remove running_in_shell. Rename stop_after_attach to
4802 stop_soon_quietly, and use it in a few other places where we want
4803 to just call wait_for_inferior and get control back on the first
4804 trap. trap_expected now never takes a value > 1.
4805 (init_wait_for_inferior): Initialize static vars when a new
4808 main.c (gdbinit): Add new hook for .gdbinit file name, let
4809 it be overridden by config files as GDBINIT_FILENAME.
4810 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
4811 Both of these are used for VxWorks gdb.
4813 mcheck.c: rename include file "gmalloc.c" to avoid problems
4814 with system include file "malloc.c".
4816 param-no-tm.h: New include file, same as param.h but does not
4817 include the default "tm.h" file. This is used in files where
4818 the target is known, e.g. remote-eb.c or sparc-xdep.c.
4820 param.h: Now just a shell that includes tm.h and param-no-tm.h.
4822 remote-vx.c: New file, VxWorks remote debugging support. Uses
4823 RPC routines that are shared with the target system, in directory
4826 remote.c: Vectorize remote interface.
4828 source.c: Globalize source_path, and make an alias "l" for "list"
4829 since we now have the "load" command.
4831 sparc-xdep.c: Use new param-no-tm.h.
4833 symmisc.c (free_named_symtab): Add new function from Wind River.
4834 However, ifdef it out for now while we think about what it should
4837 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
4839 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
4840 non-Unix-children handle this with their own code in the target
4843 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
4844 source and target lists. Add vx-share to default list of include
4845 directories. Add new files to src and target lists: mem-break,
4846 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
4847 ${srcdir} versions of munch and createtags are used.
4849 * valops.c (find_function_addr): Split out of call_function.
4850 (call_function_by_hand): Rename call_function; this function
4851 calls functions in the target by laboriously patching the target
4852 word-by-word with the right stack, args, regs, etc.
4855 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
4857 Handle AMD 29000 a bit better.
4859 * remote-eb.c (readchar): Mask received char log to make it readable.
4860 (remote_start): Pass arguments down to executing program.
4861 Make startaddr unsigned.
4862 infrun.c (start_inferior): Accept args, pass them to
4864 infcmd.c (run_command): Pass args down to start_inferior.
4866 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
4867 the target object file format.
4868 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
4870 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
4871 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
4873 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
4875 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
4876 * TODO: We did a few things, we have more to do though.
4878 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
4879 * inflow.c (inferior_died): Clear deferred stores.
4881 * Debug problems with dummy frames and calls to the inferior.
4882 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
4883 * sparc-tdep.c (do_restore_insn): Simplify.
4884 (sparc_frame_find_saved_regs): Simplify and fix what we find.
4885 (sparc_push_dummy_frame): Simplify and fix what we push.
4886 (sparc_pop_frame): Slightly more hair here, deciding whether
4887 we are restoring a saved PC or returning to a return address in %i7.
4888 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
4890 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
4891 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
4892 * obstack.h (chunkfun): ditto.
4893 * defs.h (xmalloc, xrealloc): ditto
4895 * utils.c (quit): Grab the terminal from the child if necessary.
4897 * inflow.c (term_status_command): Rename to term_info, change
4900 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
4901 (is_delayed_branch): Speed up.
4902 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
4903 Still missing some float ops, and needs testing.
4905 * Support for input and output radixes other than base 10
4906 * defs.h (input_radix, output_radix): Declare.
4907 * expread.y (yyparse, parse_number): Handle changes of input
4908 radix, and ambiguous names-or-numbers in radixes >10.
4909 * printcmd.c (print_scalar_formatted): Print formatted hex
4910 numbers in varying column widths.
4911 * valprint.c (val_print): Use output_format to print scalar ints.
4912 (set_input_radix, set_output_radix, set_radix): Create.
4913 (set_output_radix): Set output_format from output_radix.
4914 (_initialize_valprint): add `set radix' but leave the others off.
4916 * main.c (execute_command): Let stupid questions be turned off.
4917 (_initialize_main): Handle "set stupidity", etc.
4919 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
4920 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
4922 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
4924 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
4925 bfd stuff is still screwed up, but with some manual work, it
4928 * breakpoint.c (bpstat_do_actions): Start over if a command
4929 proceeds the inferior, since the inferior will have stopped and
4930 will need to have its new stop-actions taken care of.
4932 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
4933 compiler fits, simplify it.
4935 * gdb.texinfo (directory command): Doc new dir command.
4936 source.c (directory_command): "dir" now puts things on the front
4937 of the path, moves dups up front, and handles multiple names
4938 on the command line, inserting each one in order. It also
4939 blows away cached line and full_filename info.
4941 * stack.c (backtrace_command): Skip "more stack frames follow"
4944 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
4945 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
4946 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
4947 The only odd one was Gould NP1, which had defined vprintf to
4950 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
4951 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
4952 variable, inspect_it.
4953 valprint.c (print_string, val_print): Use the global inspect_it
4954 to indicate whether to print in Epoch style or normal style.
4956 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
4958 * printcmd.c (call_command): add an alias for the "print" command
4959 which runs expressions and doesn't print the result if void.
4960 (print_command_1): implement it.
4962 * command.c: Remove #if 0'd code. Initialize all the fields
4963 in add_cmd (). Rename do_nothing_command to
4964 not_just_help_class_command, and make it externally visible.
4965 command.h: add user_commands to struct.
4966 * main.c (define_command): Don't overload c->function with a char
4967 string as well as a function pointer.
4969 * eval.c (evaluate_subexp): Reinstall tiemann changes to
4970 calling convention of value_struct_elt () that got dropped in
4973 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
4974 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
4976 * tm-sparc.h (POP_FRAME): replace some constants with defines.
4978 * sparc-xdep.c (store_inferior_registers): defer stores to regs
4979 until a good time (e.g. when we are about to run the child),
4980 saving ptrace calls.
4981 * infrun.c (proceed): handle DO_DEFERRED_STORES.
4982 * tm-sparc.h: define DO_DEFERRED_STORES.
4984 * sparc-xdep.c (store_inferior_registers): when storing float
4985 registers, don't store stack regs too. When storing the SP,
4986 however, DO store the stack regs too. This fixes a bug in which
4987 the dummy frame is not recognized when a call_function finishes,
4988 because its frame pointer (in the stack regs) was never
4990 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
4991 even though we don't know how to read them from an inferior.
4992 valops.c (call_function): Comment about storing SP.
4994 * infrun.c (save_inferior_status): Save away the original bpstat
4995 chain so it can be restored later. Install the copied version for
4996 use by whoever saved the status. It will be blow away by
4997 restore_inferior_status, and the original chain restored. This is
4998 important for people who have pointers into the original.
5000 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
5001 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
5002 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
5005 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
5007 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
5008 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
5009 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
5011 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
5013 * Merge Mike Tiemann's multiple inheritance changes from Sun.
5014 Store the baseclasses in a type struct starting from array element
5015 0 rather than from the unusual array element 1.
5017 dbxread.c: the above.
5018 (virtual_context): Add
5019 Read new debug information about which virtual function table
5020 a virtual function is from, and store it in fn_field.fcontext.
5022 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
5023 TYPE_FN_FIELD_STATIC_P.
5025 symtab.c: the above.
5026 valops.c: the above. Handle pointer casts of object *'s.
5027 (search_struct_method): Add.
5028 (value_struct_elt): First arg is now a pointer to a value, and is
5031 valprint.c: the above.
5032 values.c (value_virtual_fn_field): Add type arg. Handle
5033 offsetting to the proper object when calling virtual fns.
5035 (baseclass_addr): Add valuep arg.
5037 * README: Document the current state of BFD config (missing).
5038 * TODO, ChangeLog, Makefile.dist: Roll version.
5039 * WHATS.NEW: Add summary of changes since 3.5.
5041 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
5043 * dbxread.c (read_struct_type): Clear bit vectors whenever
5045 symtab.c (B_CLRALL): define.
5047 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
5048 using == rather than =. Huh... This fixes the dreaded problem
5049 wherein builtin_type_int becomes TYPE_CODE_FLT.
5051 * core.c (info_files): Show the inferior pid.
5053 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
5054 already knows how to look in the source directory.
5056 * Remove psymtab hair from many places. Remove duplicated code
5057 for searching symbol tables. Hide psymtabs from most places.
5058 Make it fast to get from a psymtab to its symtab.
5060 blockframe.c (blockvector_for_pc): Remove psymtab hair.
5061 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5062 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5063 dbxread.c: export psymtab_to_symtab, make it work if called N times.
5064 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
5065 new symtab completely. New psymtabs get symtab pointer
5066 initialized to zero. Remove MI warning printf.
5067 symtab.h: Comments. Add psymtab to symtab pointer.
5068 (PSYMTAB_TO_SYMTAB): New macro.
5069 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
5070 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
5072 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
5074 (print_frame_info): Avoid special-casing symbols that have not yet
5077 * source.c (open_source_file): Quick path if we have already
5078 located the source file by its full name.
5080 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
5081 find_pc_psymtab. When a name is found in the misc function
5082 vector, search the symbol table for its mangled name, not the
5083 name that the user typed.
5085 * bfd.h: Fix missing comment terminators, make #endifs match.
5087 * valarith.c (value_less): Handle unsigned int comparisons.
5088 Add FIXME about pointer compares, which assume host and target
5089 pointers are the same.
5091 * command.c (do_nothing_command): lint
5092 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
5093 fix comments on debug symbol format for visibility. Actually set
5094 visibility of symbols.
5095 main.c (echo_command): lint; use <readline/history.h>.
5096 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
5097 obstack.h (_obstack_blank): Rearrange pointer math to avoid
5098 pointing past end of allocated memory; saber complains.
5099 obstack.h: Declare the external functions that we use.
5100 valarith.h: use <string.h>
5101 solib.c (solib_add): lint.
5103 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
5105 * main.c (initialize_main): Default info_verbose to off, now that
5106 symbol reading is fast.
5107 (quit_command): Avoid clobbering exec_bfd while quitting.
5109 * Initial BFD (binary file diddling library) merger:
5110 coffread.c: Change AOUTHDR to struct exe_hdr.
5112 core.c: initialize initialized data at compile time.
5113 (core_file_command): Move from coredep.c, convert to bfd.
5114 (xfer_core_file): Convert to bfd.
5115 exec.c (exec_file_command): use bfd routines.
5117 mips-tdep.c: Remove exec_file_command and friends.
5120 * coredep.c: (fetch_core_registers) Convert core_file_command to
5121 fetch_core_registers.
5122 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
5124 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
5125 (my_bfd_read): More bogosity, which I don't think we call.
5126 (program_name): Remove this atrocity asap!
5128 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
5131 values.c: allocate_repeat_value was not clearing the
5132 optimized_out field.
5133 (value_static_field): minor stylistic fix (wrong macro was used).
5134 valops.c (value_struct_elt_for_address): didn't work for C++
5137 * signame.c (_initialize_signame): Initialize signal names once.
5139 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
5140 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
5141 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
5143 * remote-eb.c: Support user-settable baud rates on the serial port.
5145 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
5147 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
5149 * tconfig/sun3os4: Remove warning about native assembler,
5150 since it also occurs in the xconfig file.
5152 * findvar.c (registers): Allocate some slop after `registers'
5153 to prevent stray accesses from trashing the next variable.
5155 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
5156 on the sun-3, by changing the #ifdef from `sun3' (which is not
5157 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
5158 vars, which happened to follow `registers' in the executable.
5160 * readline/history.c (history_search): Heed gcc-2's advice
5161 and parenthesize && inside ||).
5163 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
5164 tm-29k.c: Insert FSF copyright headers.
5166 * remote-eb.c: Better comments.
5168 * Makefile.dist: Update to 3.91.6.
5169 * TODO: note PREPARE_TO_STORE problem.
5171 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
5173 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
5175 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
5177 * infrun.c (wait_for_inferior, at end): Don't set up
5178 prev_* if the inferior no longer exists.
5180 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
5181 CANNOT_EXECUTE_STACK.
5182 valops.c (call_function): Use it.
5184 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
5186 * inferior.h (PC_IN_CALL_DUMMY): New macro.
5187 infrun.c (wait_for_inferior, 2 places): Use it.
5189 * values.c (value_being_returned): Only use
5190 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
5192 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
5193 right thing for remote-eb.c.
5195 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
5196 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
5198 * blockframe.c: Put get_frame_saved_regs inside #if !defined
5199 (FRAME_FIND_SAVED_REGS).
5201 * findvar.c ({fetch,store}_registers): Check for
5202 REMOTE_{FETCH_STORE}_REGISTER macro.
5204 * findvar.c (get_saved_register): Add argument lval and
5205 change meaning of argument addr.
5206 findvar.c: Change calls to get_saved_register to reflect
5207 new calling convention.
5208 valops.c (value_assign): Use get_saved_register instead of
5209 find_saved_register.
5211 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5213 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
5214 an (uninitialized) pointer to one. Use "&" when passing it
5217 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5219 * coffread.c (getfilename): Use DGUX x_offset and x_name if
5222 * coffread.c (symbol_file_command): Put semicolon after
5224 Put safe_to_init_tdesc_context in #if defined (TDESC).
5225 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
5226 coffread.c: #include <sys/stat.h>.
5227 (read_coff_symtab): Typo: in_source_files -> in_source_file.
5228 Add missing ')' in check for "lc%" and friends. Remove
5230 Declare read_one_sym() at top of file.
5231 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
5232 MC68WRMAGIC can have the same value without causing a duplicate
5235 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
5237 * Allow a Makefile to be built without building the
5238 tm and xm file links that screw up builds in subdirectories.
5239 This is done with `config.gdb none', then you can do things
5240 like `make gdb.tar.Z'.
5241 * tconfig/none: Config file for no target system
5242 * xconfig/none: Config file for no host system
5243 * config.gdb: If no TM or XM files are called out by the
5244 host or target file, don't make links for them.
5246 * cplus-dem.c: Add documentation.
5248 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
5249 simple error, so the user's gdb doesn't crash due to some object
5250 file problem (e.g. somebody is rebuilding the file out from under
5253 * printcmd.c (print_address_symbolic): demangle the symbol.
5255 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
5256 Motorola copyrights in it. Make "make gdb.tar.Z" work.
5257 (alldeps.mak): sort and uniq all results from this; duplicates
5258 hose gdb.tar.Z link building. Remove RCS files from
5259 tconfig and xconfig. Add config files for sun386. Add
5260 a few odd files to OTHERS and HFILES.
5262 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
5264 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
5265 Roll version number to 3.91.5. Make lint work in bindir.
5267 * README: Document cross-debugging and new file structure.
5269 * blockframe.c: Lint. Include "value.h" to declare read_register.
5270 (find_pc_partial_function): remove duplicate line.
5272 * command.h: Lint. Declare error_no_arg and dont_repeat.
5274 * tm-news.h: Remove inadvertently duplicated stuff.
5276 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
5277 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
5279 * config.gdb: Allow `config.gdb host target' form. Clean
5280 up previous change that printed bogus messages when you just said
5283 * core.c: #include "command.h" for lint.
5286 * main.c: Remove some casts of enums. Lint.
5293 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
5295 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
5296 read it from memory. This will allow us to save ptrace calls
5297 eventually. Changed caller single_step too.
5299 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
5300 that we aren't going to use, saving many ptrace calls, especially
5301 when watchpointing or single stepping. Use some #define's for
5303 (store_inferior_registers): Ditto.
5304 (core_file_command): Use some #define's for constants.
5306 * tm-sparc.h: Add #define's for some register numbers, so we
5307 can eliminate the use of random constants in sparc-xdep.c.
5309 * stack.c (frame_command, print_frame_info, up_command,
5310 down_command) Remove frame_changed, since it
5311 causes a bug and doesn't seem to do anything useful. In some
5312 places it was used as a flag, in others as a stack level (?).
5314 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
5315 default is to use the portable (vprintf) version rather than the
5317 * xm-news.h (MISSING_VPRINTF): Add.
5319 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
5321 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
5323 * Remove stuff that forces -Bstatic linking of gdb, and warnings
5324 about linking debugged programs -Bstatic in the sun?os4 config
5325 files in tconfig and xconfig subdirectories.
5327 * main.c (main): Remove unreached exit(0) now that we exit
5330 * Create TODO file for online bug list. There are too many
5331 "little" bugs to keep track of on paper.
5333 * Change Projects file to refer to bug-gdb@cygnus.com
5334 rather than kingdon@ai.
5336 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
5338 * Makefile.dist (VERSION): 3.91.4 now.
5340 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
5341 (condense_misc_bunches): Add sanity check that misc_count is
5342 the same as the number of symbols in the bunch.
5344 * coffread.c: rename init_misc_bunches. Pass an argument
5345 to condense_misc_bunches (a zero).
5347 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
5348 every time we are called; don't rely on our caller to do it.
5349 (add_file): Remove call to init_misc_bunches.
5351 * mipsread.c: Only warn, don't error, if unknown symbol types.
5352 This keeps an old gdb from falling on its face if it sees newly
5353 extended symbol info. Rename init_misc_bunches.
5355 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
5357 * Merge in changes from Per Bothner for DECstations and other
5358 MIPS stuff. The rest is Bothner speaking:
5360 The next message is a merger of Alessando Forin's mips port with
5361 mine. I've tried to use my good if biased judgment to get
5362 the best of both. It *does* need testing.
5364 Some of the changes are general, *not* mips-specific.
5367 Didn't believe in little-endian bit order.
5368 There are still inconsistencies about whether flags
5369 like BITS_BIG_ENDIAN are integer (#if ...) or
5370 boolean (#ifdef ...). I tried to paper over them.
5372 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
5373 Moved some misc_function code that was common to
5374 {dbx,coff,mips}read.c to symtab.c.
5375 In the process, I think I cleaned things up a bit.
5376 At the same time, moved obsavestring and obconcat to symtab.c.
5379 Removed obsolete condense_addl_misc_bunches (use
5380 condense_misc_bunches(1) instead).
5383 Needed to include <sys/dir>, at least on DECstations.
5385 valops.c, mips-tdep.c, tm-mips.h:
5386 Added PUSH_ARGUMENTS macro to support funny argument-pushing
5387 conventions (when STACK_ALIGN is insufficient).
5388 Needed on mips, where doubles need 8-byte alignment,
5389 but ints only need 4.
5392 Removed cruft that was not being used.
5393 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
5396 Print $ before register-names (I think that makes things a little
5398 Never print two instructions, even if one delays.
5399 Removed hex-disassemble set_cmd. (This is not mips-specific,
5400 so I think the argument is whether it is generally worthwhile or not.
5401 I'm inclined to think not, given how easy it is to
5402 convert between radixes in gdb.)
5405 This is basically Alessando's code.
5406 It doesn't use obstacks; I changed it to use obstacks
5407 in a few minor places where using malloc causes a
5408 memory leak. (Probably, more places could/should be changed.)
5409 I added record_misc_function where it was missing.
5410 In symbol_file_command and add_file_command, I tried
5411 to make the code consistent with more recent versions.
5412 Minor sylistic changes in parse_procedure.
5413 Make a .gdbinfo. psuedo-symbol point back to the real
5414 procedure symbol (using the isym field).
5417 This is basically from my port, but with a lot of details
5418 and a number of routines merged in from Alessando's version.
5419 I basically used my code "raw" backtrace (use heuristics
5420 from the actual code, rather than symbol table info) - though
5421 the idea is Alessandro's. I feel my code is a little cleaner
5422 here, particularly in being a little more flexible, such as being
5423 able to handle gcc-produced code (which it now can).
5424 It also doesn't do frame caching (which is not useful
5425 more recent gdb versions).
5426 I also used my code for push_/pop_dummy, more or less.
5427 I tried to incorporate AF's code for testing sigtramp
5428 while backtracing; I probably got it wrong.
5429 Added mips_print_register, which tries to scrunch as much
5430 information as possible on a screen...
5431 Removed the skip-prologue set_cmd. As with hex-disassemble (see
5432 under mips-pinsn.c), I don't see anything mips-specific here,
5433 and I don't see it being all that useful anyway.
5436 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
5437 Use more register names (rather than hard-cases numbers).
5439 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
5441 * Hack up 3.90.11 changes:
5443 * Makefile.dist (depend): parameterize $(GCC).
5444 Add solib.c and solib.o.
5445 (readline): Fix vpath for both absolute or relative SRCDIR.
5447 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
5448 Also, let the part I didn't understand at least compile so
5449 I can test the rest. FIXME.
5451 * dbxread.c: Fix thinko using strcmp.
5452 (init_psymbol_list): declare static.
5453 (partial_symbol_file_open): Comment cleanups better, avoid
5454 cleaning up the string table since the caller will do that.
5455 Move the stat for mod time into symbol_file_command, temporarily.
5456 (There should be a mod time for each symbol file, eventually,
5457 to control its rereading. FIXME.)
5459 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
5460 SunOS, which gives error for shared libs otherwise. (From
5461 Schaefer, probably FIXME needs work for portability.)
5463 * solib.c: Move #include "param.h" to work.
5464 Lowercase all the Uppercase Letters In the Messages.
5465 (find_solib): Clean up inferior_so_name for debug printouts.
5466 Allow no argument, to mean all shared libraries.
5468 * symmisc.c: include param.h to get CLEAR_SOLIB.
5470 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
5472 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
5473 to 3.90.11. ChangeLog entries below are from this.
5475 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5479 * Makefile.dist (HFILES): Add tm-sunos.h.
5481 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5485 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
5487 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
5489 * sparc-opcode.h Added single-operand version of rett.
5491 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5493 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
5494 Put parens around gcc_p in expansion.
5496 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5498 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
5500 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5502 * Changes for Sun shared libraries:
5503 blockframe.c (find_pc_partial_function): If a non-text symbol
5504 is found, set *address = pc - FUNCTION_START_OFFSET.
5505 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
5506 Disable breakpoints instead of giving an error.
5507 source.c (select_source_symtab): Initialize cs_pst.
5508 symmisc.c: Call CLEAR_SOLIB if defined.
5509 symtab.h: Make text{low,high} CORE_ADDR not int.
5510 (psymtab): New field addr.
5512 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
5513 (record_misc_function): Give correct type for N_DATA symbols.
5514 (condense_misc_bunches): do "misc_function_count = j" regardless
5516 Take code which is shared between symbol_file_command and
5517 add_file_command and put it into partial_symbol_file_{open,read}.
5518 Split add_file_command into add_file_command and add_file.
5519 Make psymtab_to_symtab read in the string table if the file
5521 Two new parameters to read_dbx_symtab and start_psymtab.
5522 tm-sunos.h: New file.
5524 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5526 * infcmd.c: Change cont_command to continue_command and "cont"
5529 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5531 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
5533 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
5535 * values.c (USE_STRUCT_CONVENTION): Check for structures of
5536 size 1,2,4,8 rather than size < 8.
5538 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
5539 as necessary, not just once.
5541 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
5543 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5545 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
5547 * tm-news.h: Add CALL_DUMMY_*.
5549 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
5551 * config.gdb: In list_host, list_target, use ${i}, not $i.
5553 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5555 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
5557 * sparc-opcode.h: Change all store floating-point state register
5558 instructions to have the right match & lose fields.
5560 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5562 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
5564 config.gdb: If srcdir != ., create readline directory and
5565 copy a makefile into it.
5567 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
5568 consistency with POSIX.
5570 * breakpoint.c (bpstat_stop_status): Disable watchpoint
5571 when we exit its exp_valid_block.
5573 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
5575 * Makefile.dist: Bump version to 3.91.3.
5577 * Clean up handling of breakpoint commands (somewhat).
5578 Prompted by Tiemann bug report "cont 10" doesn't work any more.
5580 inferior.h: Add breakpoint_proceeded to inferior status struct
5581 and globals; save it and restore it.
5582 (clear_breakpoint_commands): Cleanup, remove old #define.
5584 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
5585 (save_inferior_status, restore_inferior_status): handle it also.
5586 (proceed): Remove earlier code that set breakpoint_proceeded.
5587 It is now set only in clear_proceed_status.
5588 (clear_proceed_status): Cleanup, use bpstat_clear rather
5589 than clear_breakpoint_commands. No callers need the stop_bpstat
5590 between clear_proceed_status and proceed.
5592 infcmd.c: Add breakpoint_proceeded definition and comment.
5593 (cont_command, jump_command, signal_command): Move call to
5594 clear_proceed_status right next to call to proceed.
5596 breakpoint.c (bpstat_do_actions): Avoid clobbering our
5597 caller's argument while running down the chain of breakpoints.
5598 Use new variable "breakpoint_proceeded" to determine when
5599 a command that it executes moves the inferior past the
5601 (bpstat_clear): Handle NULL argument.
5602 (bpstat_clear_actions): Avoid useless call to
5603 breakpoint_auto_delete.
5604 (delete_breakpoint): Clean up bpstat's that are pointing to
5605 the deleted breakpoint from the stop_bpstat chain.
5606 (breakpoint_auto_delete): Simplify.
5608 * Clean up handling of EOF, error on stdin, etc. This was
5609 prompted by a network problem that caused gdb to go into an
5610 infinite loop filling up its malloc'd memory.
5612 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
5613 not clear_breakpoints_commands, which is now gone.
5614 (main): If command_loop returns (e.g. from EOF on stdin), do
5615 a quit_command (looping back to command_loop if quit_command
5616 doesn't really quit).
5617 (command_loop): check result from command_line_input and
5618 exit if it returns NULL, rather than passing the NULL to
5620 (gdb_readline): Free malloc'd result space before returning
5623 * utils.c (query): Handle C-d to mean "yes", just as if the
5624 input was not a terminal. Also avoid infinite loop if EOF
5625 occurs in mid-input-line before newline. This allows
5626 query to be used at EOF on stdin with reasonable results.
5628 * infrun.c (proceed): Set breakpoint_proceeded.
5630 * values.c (value_as_long): Avoid infinite recursion for enums.
5631 (_initialize_values): Fix typo in help msg (kingdon).
5633 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
5634 RL_LIB for linking. This allows -lreadline for linking
5635 and nothing for dependencies, once readline is a real library.
5637 * config.gdb: Jim Kingdon: give useful error message if the
5638 host or target type is not recognized.
5640 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
5641 it just defines it. Dumb, but deal with it.
5643 * Jim Kingdon suggests:
5644 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
5646 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
5648 * Makefile.dist (VERSION): Bump version # to 3.91.2.
5650 * Clean up Bothner's changes.
5652 * blockframe.c (clear_pc_function_cache): New function.
5653 * blockframe.c: remake cache_pc_function_* static.
5654 * dbxread.c (symbol_file_command): remove references to
5655 cache_pc_function_* variables.
5656 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
5657 * printcmd.c: Avoid kludging a global variable (addressprint)
5658 to avoid printing the address of a string twice. Instead,
5659 pass the format letter 's' down low enough that it can be seen
5660 to avoid this problem.
5661 (print_formatted): Pass format arg to value_print.
5662 (restore_addressprint): Remove function.
5663 (do_examine): Avoid hacking addressprint, cleanups and such.
5664 (print_frame_args): Add a comment to a Bothner change.
5665 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
5666 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
5667 to wipe out the values cached in blockframe.c.
5668 * symtab.c (find_method): Add comment saying how big you must
5669 allocate to be "big enough". Per being terse again.
5670 * valprint.c (val_print): Handle format letter "s" to print
5671 strings without addresses. Add comment to vtbl printing code
5672 which casts with wild abandon. Rearrange reference-printing
5674 @0xaddr: value (print w/addressprint)
5675 value (print w/~addressprint)
5676 @0xaddr (parameter lists w/addressprint)
5677 or nothing (parameter lists w/o addressprint)
5679 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
5681 * Merge more changes from Per Bothner:
5683 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
5684 annoying) that I tried to improve it. Here are my suggestions.
5686 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
5689 Do automatic de-reference when taking the address of a reference.
5691 Don't deref_ref when printing parameter lists.
5693 More attempts at treating refernences properly.
5695 In val_print, if deref_ref==0, don't print dangling " = ".
5697 Add COERCE_REF macro, which de-references an REF.
5699 * Merge changes from Per Bothner:
5701 * Fixed (Sony news)-specific configuration problems.
5702 * Fixed other problems with using vanilla pcc and libc (enum problems;
5703 assumption that vsprintf exists).
5704 * Some major speed-ups (finc_pc_partial_function now caches a match;
5705 parsing avoids duplicate symbol_lookup calls).
5706 * Changed handling of baseclasses (no longer use baseclasses field
5707 of struct type, use the first n_baseclasses fields instead).
5708 * Various minor changes/fixes, most C++-related.
5711 Cache the most previous match from find_pc_partial_function.
5712 (Save both low and high ends of matching function's pc range.)
5713 This speeds up the loop of infrun.c:wait_for_inferior quite
5714 a bit, and makes step/next commands much zippier.
5716 Added an enum->int cast (otherwise, some compilers barf).
5718 No longer set baseclass offset to 0, since multiple
5719 inheritance now mostly works.
5720 Added a number of casts, to shut up compiler warnings
5721 (after stabs where made enums, not ints).
5722 When discarding a symbol table (in symbol_file_command),
5723 must clear the cache introduced in blockframe.c.
5724 Don't convert $vtbl_ptr_type to vtbl any more.
5725 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
5726 Mask off sign bit emitted by g++ for virtual table offset.
5727 Set voffset to -1 (not 1) for static member functions.
5729 Changed parsing/lexing of names to avoid doing symbol lookup twice
5730 (once when lexing to determine symbol class, once for real).
5731 Now only call symbol_lookup once. Fields of 'this' win especially big.
5733 Subpress printing addr twice in the case of 'x/s addr'.
5735 lookup_basetype_type is no longer used.
5736 Add find_methods as recursive helper function to decode_line_1.
5737 This allows multiple inheritance to work.
5738 Also, once one or more matches has been found, do not look in
5739 base-classes. (Baseclass methods would be overridden, anyway.)
5741 Removed baseclasses array in struct type.
5742 Instead of using baseclasses[i], use fields[i-1].
5743 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
5744 Changed sign convention of voffset (previous was inconsistent).
5746 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
5748 Used to assume existence of vsprintf. Re-written to not need it
5749 if HAVE_VPRINTF is undefined.
5751 typecmp was too pessimistic. Made it less so.
5753 Don't print space after address.
5754 If vtable points to a misc symbol (with 0 offset), print it,
5755 since that indicates the actual class of the object.
5756 Changed ype_print_derivation_info to use new inheritance
5757 scheme (without baseclasses vector).
5759 In value_primitive_field, fixed some bugs left over from previous set of fixes.
5760 Also, changes needed because TYPE_BASECLASSES were removed.
5762 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
5764 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
5767 If there is no path set, and the symbols don't indicate what directory
5768 a file was compiled in, look in the current directory. But either
5769 a path or a known compilation directory will prevent this.
5772 Three independent bug fixes:
5773 * Remove the #if 0 block that breaks some stuff.
5774 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
5775 adapt gdb to either SunOS 4.0.* or 4.1.
5776 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
5779 Instantiate the class T when looking for methods in it. (Tiemann@sun)
5782 (type_print) Demangle the name being printed.
5783 (type_print_base) Handle botched demangling without coredump (tiemann).
5786 (check_stub_method): Document routine.
5787 (tiemann) fix bug for no-arg functions
5788 Avoid clobbering beyond end of malloc'd storage.
5789 Terminate the argument list properly.
5791 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
5793 * Changes merged by John Gilmore:
5796 In breakpoint_1, use new print_address_symbolic instead
5797 of find_pc_partial_function. (This forces use of assembler-level
5798 addresses, and avoids misleading non-mangled source-level names.)
5800 Generalize ansi argument such that -1 means skip arglist totally.
5801 Removed global variable print_ansi_qualifiers (which made
5802 code non-reentrant), in favor of extra explicit arguments
5803 to internal routines.
5805 Add new helper function print_address_symbolic.
5806 Use find_pc_misc_function instead of find_pc_partial_function
5807 (since we want assembler-level symbols here).
5809 Print unknown function as just "f (...)", not "f (...) (...)".
5810 Use new fputs_demangled explicitly.
5812 Fixed a typing violation (problem: value.h cannot be imported
5813 without renaming many variable in this file).
5814 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
5815 decode_line_1: Moved forward some never-reached code.
5816 Made decode_line_2 skip function prologues correctly.
5818 fputs_filtered should not demangle by default.
5819 Add new fputs_demangled to demangle on demand..
5821 Change value_struct_elt to use value_primitive_field (using recursive
5822 utility function search_struct_field). This allows foo.bar to work
5823 for multiple inheritance (so far only for data fields).
5824 Change check_field in the same way (recursive helper function
5825 to support multiple inheritance).
5826 (Note: there are more of these problems that I haven't fixed.
5827 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
5828 value_of_this: 'this' symbol name is now just "this", note "$this".
5830 Don't print static members.
5831 Avoid printing "members of <type>" if there are none.
5832 Simplified type_print_derivation_info by merging duplicate code.
5833 Remove useless blank lines in type_print_base (ptype command).
5835 Added declaration of new routine value_primitive_field.
5837 Added value_primitive_field which is generalized version of
5838 value_field that can handle multiple inheritance (non-zero offsets etc).
5839 Re-implemented value_field to call value_primitive_field.
5841 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
5843 * infcmd.c -- insert else to avoid 'delete env' coredump when you
5844 delete the whole environment. Karl Berry reported the bug.
5845 * source.c - fix openp to avoid //'s in filenames, which
5846 trigger an Emacs bug causing it to not be able to find files
5847 when running gdb in a window.
5848 * dbxread.c - zap the #if 0 that botches the add-file code.
5849 It seems to work a lot better without all the code commented out.
5851 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
5853 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
5856 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
5858 * Makefile - added a ${CFLAGS} to a couple of entries,
5859 added remote-sa.sparc.c
5860 * added remote.sa-sparc.c, a modification of remote.c
5861 which conducts a dialog directly with the SparcStation prom.
5862 * breakpoint.c, infrun.c, sparcdep.c added
5863 remote_insert_breakpoint(), and remote_remove_breakpoint()
5864 to breakpoint.c instead of directly writing breakpoint instructions.
5865 * sparcdep.c on remote_debugging,there is no need
5866 to remove signle step breakpoint instructions.
5867 * main.c added "-epoch" flag and "int epoch_interface" to main.c
5869 * printcmd.c - epoch interface sends lisp expressions to open up
5870 epoch windows on inspection.
5871 * valprint.c - added arrayprint, and addressprint and made adding
5872 format controls easier
5873 * wait.h added a couple of undef's because we were getting
5874 complaints about WSTOPSIG and WTERMSIG begin redefined.
5877 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
5879 * symtab.c (decode_line_1): Add support for handling method stubs
5880 in the type information.
5882 Tue Jul 3 09:39:18 1990 Michael Tiemann (tiemann at masham)
5884 * values.c (baseclass_addr): Run loop from INDEX+1 to
5885 N_BASECLASSES; otherwise, we can still get into a loop.
5886 @@ This should be restructured to use a cleaner search strategy.
5888 Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
5890 * dbxread.c (define_symbol,read_type): Grok GNU C++'s new
5891 abbreviation "Tt" for tags which have the same name as their
5894 Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham)
5896 * symtab.c (list_symbols): add ability to set breakpoints on all
5897 the functions which match a particular regular expression.
5899 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
5901 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
5902 should print ANSI qualifiers (such as `const' and `volatile').
5903 All callers changed to call with ANSI == 1, except from
5904 `check_method_stub', which uses old-style syntax.
5906 * symseg.h (struct fn_field): Remove unneccessary `args' field.
5907 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
5909 * values.c (check_stub_method): New function.
5911 * cplus-dem.c (do_type): Handle "long long" (encoded as 'x').
5913 * dbxread.c (read_type): Handle new GNU C++ method type stubs.
5914 * valprint (type_print_base): Ditto.
5916 * symtab.c (gdb_mangle_typename): New function.
5918 Tue Jun 5 00:18:43 1990 Michael Tiemann (tiemann at gzilla)
5920 * breakpoint.c (catch_command): New function. Provides a
5921 mechanism to set breakpoints based on catch clauses.
5922 (disable_catch): Similar, but disables breakpoints on catch
5924 (delete_catch): Similar, but deleted breakpoints on catch clauses.
5926 Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla)
5928 * blockframe.c (blockvector_for_pc): New function.
5929 * blockframe.c (block_for_pc): Changed to call
5930 `blockvector_for_pc' and get the block itself.
5932 * stack.c (catch_info): New function. Prints info about
5933 exceptions which can be caught in the current frame.
5934 * stack.c (print_frame_label_vars): New function. Similar to
5935 `print_frame_local_vars'.
5936 * stack.c (print_block_frame_labels): Prints out labels that are
