1 Sat Dec 7 18:13:11 1991 Fred Fish (fnf at cygnus.com)
3 * i386-tdep.c: Fix a problem on i386 systems where buffered code
4 stream access was failing to take into account the minimum size
5 granularity of the code section. For now, the buffering is simply
6 disabled. There is a similar problem in the i386 disassember code
7 that has not yet been fixed (FIXME).
9 * gmalloc.c: Use macros to hide some of the ugly casting required
10 in the previously applied fix for pointers with high bits set.
12 Sat Dec 7 16:49:35 1991 John Gilmore (gnu at cygnus.com)
14 * Makefile.in: Roll VERSION to 4.3.1.
16 Sat Dec 7 04:12:35 1991 John Gilmore (gnu at cygnus.com)
20 * Makefile.in: Roll VERSION to 4.3
21 * README, TODO, WHATS.NEW, depend: Update.
23 * inflow.c (terminal_inferior): Avoid error msg if attached.
25 * gmalloc.c: Fix bug that causes malloc & free to
26 fail on systems where pointers have the high bit set (0x800efcf0
27 for example). The problem is that the difference between two
28 pointers is a signed integer, so the computation
30 (char *) 0x800efcf0 - (char *) 0
32 yields a negative value. The sign of the result of the modulus
33 operator is machine dependent for negative operands, thus it is
34 possible for it to end up negative. From Fred Fish.
36 Sat Dec 7 00:00:15 1991 K. Richard Pixley (rich at rtl.cygnus.com)
38 * Makefile.in: install using INSTALL_PROGRAM and INSTALL_DATA.
39 added clean-info. added some standards.text support and made it
40 look like our other Makefiles.
42 * configure.in: mark this directory target dependent. configure
43 now runs entirely in objdir so make existence tests and
44 references against ${srcdir}.
46 Fri Dec 6 08:30:36 1991 Fred Fish (fnf at cygnus.com)
48 * dwarfread.c (enum_type, struct_type): Fixes for opaque and
49 anonymous enumerations, structures, and unions. Now passes all
50 the current gdb test suite tests.
52 Thu Dec 5 22:46:13 1991 K. Richard Pixley (rich at rtl.cygnus.com)
54 * Makefile.in: idestdir and ddestdir go away. Added copyrights
55 and shift gpl to v2. Added ChangeLog if it didn't exist. docdir
56 and mandir now keyed off datadir by default.
58 Thu Dec 5 21:53:21 1991 John Gilmore (gnu at cygnus.com)
60 * symtab.c (decode_line_1): If SKIP_PROLOGUE leaves us in
61 mid-line, be more careful about possibly advancing to the next line.
63 Thu Dec 5 18:59:51 1991 Michael Tiemann (tiemann at cygnus.com)
65 * cplus-dem.c (cplus_demangle): Call `string_need' when

68 Thu Dec 5 18:19:43 1991 Fred Fish (fnf at cygnus.com)
70 * dwarfread.c (enum_type): Build a correct TYPE_NAME, add a
71 symbol to the symbol table for each member of the enum.
73 * dwarfread.c (struct_type): Build a correct TYPE_NAME.
75 * dwarfread.c (add_enum_psymbol): New function to extract enum
76 member names and add them to the partial symbol table while
77 building partial symbol tables.
79 Thu Dec 5 17:31:05 1991 John Gilmore (gnu at cygnus.com)
81 * symtab.c (check_stub_method): Must allocate two extra argument

86 * inflow.c (child_terminal_info): Supply missing '"' character.
88 * buildsym.c (define_symbol): Supply missing parenthesis.
90 Thu Dec 5 03:34:21 1991 John Gilmore (gnu at cygnus.com)
92 * coredep.c (fetch_core_registers): Fencepost error. Fixed by
93 Jay Lepreau <lepreau@cs.utah.edu>.
95 * inflow.c: Remember whether GDB has a terminal. Avoid switching
96 terminals back and forth if we don't have one.
98 * c-exp.y (parse_number): Zero is not an unsigned int constant!
99 * dbxread.c (read_dbx_symtab): Enum type numbers can be in (1,2) form.
101 Improve type parsing.
102 * buildsym.c (define_symbol, read_range_type): Add
103 long_kludge_name that passes the names of range types being
104 defined, down to where we must choose between 'int' and 'long'
105 variants. This fails on Sun C anyway since the compiler itself is
106 confused between int and long.
107 (read_array_type, cleanup_undefined_types): Correct the size of
108 array type whose element-type size isn't immediately known.
110 Early preparation to blow away many builtin types, building them
111 on the fly as needed. Don't compare types to builtin types with
112 ==; examine the relevant fields instead.
113 * coffread.c (process_coff_symbol: C_ARG, C_REGPARM): Avoid ==.
114 * buildsym.c (define_symbol, case 'p'): Avoid ==.
115 * valops.c (value_arg_coerce): Avoid ==. Don't assume host and
116 target types are the same.
117 * valprint.c (val_print): I finally understand arrays, remove FIXME.
119 * symmisc.c (printpsyms_command): Reduce redundancy, and put all
120 addresses in GDB itself into parens for easy cleanup and diffing.
122 Wed Dec 4 21:05:30 1991 Fred Fish (fnf at cygnus.com)
124 * dwarfread (enum_type): Arrange for the order of enumeration
125 members to match the source code order; not the order in the
126 Dwarf information, which is explicitly reverse order.
128 Wed Dec 4 18:24:39 1991 John Gilmore (gnu at cygnus.com)
130 * main.c (input_from_terminal_p): Check whether GDB has a
132 (initialize_main): Revise doc for `set editing'.
134 Wed Dec 4 15:36:39 1991 Fred Fish (fnf at cygnus.com)
136 * dwarfread.c (struct_type): Handle structures and unions which
137 contain DIE's other than just member dies.
139 Wed Dec 4 01:59:05 1991 John Gilmore (gnu at cygnus.com)

144 Tue Dec 3 17:24:57 1991 John Gilmore (gnu at cygnus.com)
146 * Makefile.in: VERSION 4.2.96.
148 * main.c (initialize_main): Revise command descriptions.
149 * command.c (show_user): `info user' -> `show user'.
150 * symtab.c (_initialize_symtab): Typo in `info types' desc.
152 * coffread.c (coff_symfile_read): Avoid select_source_symtab,
153 since it is not needed and can cause errors when examining ".o"s.
154 (read_coff_symtab, decode_base_type): Use complain, not printf.
155 Print symbol name, not its number.
156 Remove "#if defined(clipper) #define BELIEVE_PCC_PROMOTION", which
157 someday should go in a clipper target config file.
159 * symfile.c (compact_misc_function_vector): Handle empty vector.
160 (complain, clear_complaints, syms_from_objfile): Fix complaint
162 * xcoffexec.c: Change syms_from_objfile caller.
164 * sparc-xdep.c: Force tm-file as tm-sparc.h, to make it compile
165 when configured for cross debugging. FIXME, this needs a more
168 Mon Dec 2 11:04:05 1991 Per Bothner (bothner at cygnus.com)
170 * mips-tdep.c (init_extra_frame_info): Float register
171 'i' has gdb-internal number 'FP0+i', not '32+i'.
172 * mipsread.c (new_symbol): Translate g++ special
173 symbol "$t" to "this".
175 Sat Nov 30 21:29:55 1991 Steve Chamberlain (sac at cygnus.com)
176 Changes due to include file renaming:

194 * configure.in: Add SVR4 i386 configurations.
196 * config/mh-i386v4, config/mt-i386v4, tm-i386v4.h, xm-i386v4.h:
197 New files for i386/SVR4.
199 * tm-i386v.h: Allow START_INFERIOR_TRAPS_EXPECTED and
200 DECR_PC_AFTER_BREAK to be predefined by files including
203 * i386-tdep.c: Add supply_gregset(), fill_gregset(),
204 supply_fpregset(), and fill_fpregset() functions, which are
205 target dependent support functions for the SVR4 /proc register
208 * dwarfread.c (enum_type, struct_type): Expand recognized
209 compiler generated tags to include symbols beginning with '.' as
212 * symtab.c (sources_info): Change simple printf of error message
215 Fri Nov 29 16:04:21 1991 Roland H. Pesch (pesch at cygnus.com)
217 * doc/gdb.texinfo: remove leading comments that survived M4 but
218 described its role in the doc; add one more font to colophon;
219 strengthen disclaimer about unsupported configs.
221 Wed Nov 27 01:23:41 1991 John Gilmore (gnu at cygnus.com)
223 Fix bugs in C++ debugging.
225 * symtab.h: target_type is not used in record types.
226 Eliminate TYPE_MAIN_VARIANT and TYPE_NEXT_VARIANT. Eliminate
227 lookup_method_type. Add TYPE_TYPE_SPECIFIC macro.
229 * symtab.c (lookup_member_type): Don't chain them up, just
230 allocate one in symbol_obstack when we need one.
231 (allocate_stub_method): Build stub in symbol_obstack.
232 (check_stub_method): Move here from values.c. Don't deallocate
234 (lookup_method_type): Gone now.
236 * buildsym.c: Handle g++ v1 stabs a little bit better.
237 Change some C++ parsing error()s to complain()ts.
238 * buildsym.c, findvar.c, printcmd.c, symtab.c: Make unions and
239 structs have the same representation and work the same as far as
241 * buildsym.c, symtab.c, values.c: Remove all references to
242 TYPE_MAIN_VARIANT and TYPE_NEXT_VARIANT.
244 * valops.c: Improve comments and indentation. Only call
245 check_stub_method when the stub flag is on.
246 * valprint.c: Fix or mark minor bugs and unportabilities.
248 * coffread.c (anonymous unions): Allocate a cplus structure.
250 * mipsread.c: Eliminate "template" types. Build new, real
251 types whenever we need them. Allocate cplus structures as needed.
252 Bulletproof the type parsing a bit more. Mark storage leaks.
253 (parse_type): Copy TYPE_TYPE_SPECIFIC when copying a real type
254 on top of a partial type.
256 Fri Nov 22 16:39:57 1991 John Gilmore (gnu at cygnus.com)
258 * inflow.c (terminal_inferior): Check the results of ioctl's, and
259 print a message if any of them fail.
260 (terminal_ours_1): Store result of ioctl's for debugging, but
261 don't print (the terminal isn't ours...).
263 * tm-tahoe.h (FRAME_ARGS_ADDRESS): No need to offset from frame
266 * m2-exp.y (MAX, MIN): Rename to MAX_FUNC, MIN_FUNC to avoid
267 conflicts with system header files.
269 Fri Nov 22 08:27:40 1991 John Gilmore (gnu at cygnus.com)
271 * Roll VERSION to 4.2.95.
273 * buildsym.c, coredep.c, mem-break.c, xcoffread.c: Put <stdio.h>
274 first, before defs.h.
275 * config/mh-i386sco: Override compiler to gcc, print warning.
276 * configure.in: Handle i386-none-aout rather than i386-aout-none.
277 * infptrace.c, language.h, utils.c: Lint.
278 * m2-exp.y: #undef MAX and MIN in case system includes set them.
279 * xm-tahoe.h: Set HOST_BYTE_ORDER. Include system versions of
280 {BIG,LITTLE}_ENDIAN and the INT_MAX family first, to avoid
281 redefinition warnings.
282 * defs.h: Reorder things so that the xm-file gets first crack
283 at #define's, followed by defs.h and then the tm-file.
284 * Makefile.in: Remove spaces after 'ignore exit code' - flags.
285 Late-model BSD 'make's don't cope with them.
287 Thu Nov 21 23:48:56 1991 John Gilmore (gnu at cygnus.com)
289 * Makefile.in: Roll new files into various lists.
291 Thu Nov 21 18:26:11 1991 Fred Fish (fnf at cygnus.com)
293 * dwarfread.c (struct_type): Must initialize the c++ specific
294 portion of union types as well as struct types, since gdb attempts
295 to reference the c++ specific info for both types.
297 Thu Nov 21 10:23:52 1991 John Gilmore (gnu at cygnus.com)
299 * Makefile.in: Roll VERSION to 4.2.90.

306 solib.c, symtab.h, tm-umax.h, valprint.c: Lint.
307 * tm-convex.h, tm-hp300hpux.h, tm-merlin.h, tm-sparc.h,
308 xm-merlin.h: Avoid host include files in target descriptions.
309 * getpagesize.h: Removed, libiberty copes now.
310 * Makefile.in: Remove getpagesize.h, param.h, param-no-tm.h.
312 * exec.c (exec_files_info): If `verbose' is set, show file offset
315 * main.c: Use getcwd rather than getwd.
316 * standalone.c: Fake getcwd rather than getwd.
317 * xm-*.h: Remove fake values of MAXPATHLEN.
319 * xcoffexec.c: Add /* */ to #if 0'd thing to help ANSI.
321 Wed Nov 20 18:35:56 1991 John Gilmore (gnu at cygnus.com)
323 * Remove gdb/hp-include. Support for HP a.out oddities should be
324 in BFD, not in GDB. Move gdb/hp-include/a.out.h to include/a.out.hp.h.
326 * infptrace.c, tm-sun386.h: Cashier <a.out.gnu.h>, remove refs.
328 * configure.in, xconfig, tconfig, Makefile.in, doc/gdbint.texinfo:
329 Makefile fragments for various hosts and targets now come from
330 gdb/config/mh-* and gdb/config/mt-*. This is for consistency with
333 * rs6000-pinsn.c, rs6k-opcode.h: Clean up.
334 * rs6k-opcode.def: Delete.
336 Wed Nov 20 05:04:40 1991 Fred Fish (fnf at cygnus.com)
338 * dwarfread.c: Recognize obsolete form of AT_element_list
339 attribute still used by at least one AT&T compiler, and possibly
342 Tue Nov 19 07:53:55 1991 Fred Fish (fnf at cygnus.com)
344 * dwarfread.c (enum_type, struct_type): Ignore names invented by
345 helpful compilers for anonymous structs, unions, and enums.
347 * c-exp.y, m2-exp.y: Add defines for yymaxdepth, yy_yys, and
348 yy_yyv, so multiple parsers produced by SVR4 versions of yacc
349 can coexist in the same executable without collision.
351 * symtab.h: Add declaration for lookup_template_type() to kill
352 compiler warnings about conversions from int to pointer.
354 Mon Nov 18 17:45:18 1991 Fred Fish (fnf at cygnus.com)
356 * procfs.c: Move inclusion of defs.h to before param.h, as in
357 all the other source files that include both. This is required
358 to supply some typedefs that are used in files included by param.h.
360 * m68k-tdep.c (m68k_skip_prologue): Add generic m68k support for
361 skipping function prologues, ala the other cpu families (i386,
362 mips, m88k, etc). Add the ability to skip movm and fmovm
363 instructions in the prologues. Still needs support for profile
364 (-p compiled) prologue sequences (FIXME).
366 * tm-68k.h: Change SKIP_PROLOGUE macro to use the new generic
367 m68k prologue skipping function by default.
369 * tm-altos.h, tm-isi.h: Continue to use the old definition of
372 Mon Nov 18 15:12:45 1991 John Gilmore (gnu at cygnus.com)
374 * Makefile.in: Remove tdesc stuff, and extra blanks before colons.
375 * blockframe.c: Remove tdesc-related code. Default
377 * infrun.c: Remove tdesc-related code.
378 * m88k-tdep.c (frame_chain_combine, init_frame_pc): Remove copies
379 of defaultable things.
380 * tm-m88k.h: New file, common to all Moto 88k target configs.
381 Derived from tm-delta88.h.
382 * tm-delta88.h: Use it.
383 * xm-m88k.h: Common file for 88K hosts. Remove obsolete stuff.
384 * xm-delta88.h: Use it.
385 * tm-*.h: Remove FRAME_CHAIN_COMBINE macros, since all are
387 * coffread.c: Remove tdesc stuff.
388 * tconfig/delta88, tconfig/m88k: Remove tdesc stuff.
389 * xconfig/m88k: Rename tm-88k.h to tm-m88k.h.
391 Mon Nov 18 13:51:37 1991 Per Bothner (bothner at cygnus.com)
393 * source.c (open_source_file): If openp fails, try again
394 using just the base (non-directory) part of the filename.
395 This solves various annoying problems, such as when the
396 source was compiled with an absolute pathname - and the
397 source files have moved. Or if the source was compiled
398 using a relative pathname, it can be more convenient
399 to just specific the source directory to the dir command.
401 Mon Nov 18 00:04:41 1991 Fred Fish (fnf at cygnus.com)
403 * cplus-dem.c (munge_function_name): Add missing third arg to
404 instance of call to do_type().

407 AT_deriv_list, AT_loclist, AT_incomplete, AT_const_data,
410 Sun Nov 17 16:20:53 1991 Michael Tiemann (tiemann at rtl.cygnus.com)
412 * symtab.h (struct type): Moved C++-specific fields into new type
413 `struct cplus_struct_type'. Now takes 10% less memory. Many
415 * symtab.c (init_type): Don't set fields belonging to
416 TYPE_CPLUS_SPECIFIC unless TYPE is TYPE_CODE_STRUCT.
417 * buildsym.c (read_type): Allocate TYPE_CPLUS_SPECIFIC for
419 (read_struct_type): Ditto. Also, add comments about how we can
420 deduce TYPE_VPTR_FIELDNO from inheritance info and fieldname info.
421 * coffread.c (decode_base_type): Allocate TYPE_CPLUS_SPECIFIC for
423 (read_struct_type): Ditto.
424 * dwarfread.c (struct_type): Ditto.
426 * symtab.c (read_range_type): Don't set TYPE_MAIN_VARIANT.
427 (lookup_pointer_type): Don't use or set TYPE_MAIN_VARIANT.

437 * mipsread.c (parse_partial_symbols): patch to keep DEC C
438 compiler from making gdb bomb out. Thanks to Ed Santiago!
440 Thu Nov 14 19:27:30 1991 Fred Fish (fnf at cygnus.com)
442 * symfile.c: Add function compact_misc_function_vector() to
443 remove duplicate misc function vector entries. See comments
444 in source for why this is necessary/desirable.
446 * dwarfread.c: Add misc function type parameter to internal
447 record_misc_function(). Remove calls to init_misc_bunches()
448 and condense_misc_bunches(), these are now done in elfread.c.
450 * elfread.c: Add support for reading bfd canonical symbol tables
451 and generating misc function vector entries for global and
452 absolute symbols. Do calls to init_misc_bunches() and
453 condense_misc_bunches() where they will enclose all calls to
454 record_misc_function(), including those in dwarfread.c.
456 Thu Nov 14 17:02:11 1991 Roland H. Pesch (pesch at cygnus.com)
458 * doc/Makefile.in: new targets gdb.me, gdb.ms, gdb.mm
459 (roffable documentation).
460 * doc/gdb.texinfo: embedded hints (as comments) for better
461 texi2roff conversion.
463 Thu Nov 14 13:18:25 1991 John Gilmore (gnu at cygnus.com)
465 * m88k-tdep.c (examine_prologue): Deal with OR instructions
466 that shuffle parameters into other regs.

473 gdb.z into the right place.
475 Wed Nov 13 16:45:13 1991 John Gilmore (gnu at cygnus.com)
477 Motorola 88000 port without tears, I mean without tdescs.
479 * m88k-tdep.c: Blow away all tdesc stuff.
480 Provide functions for all the frame-related macros in
481 tm-delta88.h. Adopt i960-style EXTRA_FRAME_INFO.
482 (examine_prologue, frame_find_saved_regs, skip_prologue): borrow
483 from i960-tdep.c and adapt to the function prologues on the 88k.
484 (read_next_frame_reg): Borrow from mips-tdep.c.
485 FIXME: frame_locals_address should go away.
487 * tm-delta88.h: Dump all the tdesc stuff.
488 Macros for all frame-related stuff call fns of same name.
489 Remove duplicated definitions. FP_REGNUM becomes same as
492 * xm-88k.h: Eliminate lots of library dependencies, now handled
493 in libiberty. Eliminate KDB nonsupport.
495 * doc/gdbint.texinfo: Add rudiments on frames. FIXME, add more.
498 * stack.c (frame_info): Mark frameless functions.
499 Print locals address (FIXME, remove if same).
500 * blockframe.c: Comment changes, FIXME after.
501 * coffread.c: Even without TDESC, need to zap "@" symbols.
502 Don't register for wierd format names; change the names in BFD.
504 * alloca.c, language.c, tdesc.c: Lint.
505 * tdesc.c, tdesc-lib: FIXME: remove these.
507 Tue Nov 12 19:30:22 1991 John Gilmore (gnu at cygnus.com)
509 * Makefile.in: Add tdesc library support. Fixups to lint,
512 Tue Nov 12 13:43:26 1991 Per Bothner (bothner at cygnus.com)
514 * symtab.c (decode_line_1): Remove spurious call to operator_chars.
516 Allow setting breakpoints on C++ destructors.
517 * valops.c (destructor_name_p): Don't check TYPE_HAS_DESTRUCTOR,
518 since it lies. Rely on callers to catch missing destructors.
519 * symtab.c (decode_line_1): For example (see above), here.
520 * buildsym.c, symtab.h: Remove TYPE_FLAGS_HAS{CON,DE}STRUCTOR
521 flags since they are no longer used.
523 Fixes to support C++ methods with functional parameters.
524 * c-exp.y (func_mod rule): Allow (and ignore) list of parameter
525 types in a function type.
526 * eval.c (parse_and_eval_type), value.h: New function,
527 parse_and_eval_type, is based on old code from check_stub_method.
528 But don't actually evaluate the cast, since that calls
529 value_cast(), whcih may fail. Just extract the type
530 from the parsed expression.
531 * values.c (check_stub_method): While looping through the
532 arguments, adjust depth *after* parameter has been handled.
533 Replace call and setup of parse_and_eval with new function
536 Tue Nov 12 09:40:07 1991 Fred Fish (fnf at cygnus.com)
538 * utils.c, rem-multi.shar: Remove fixed arg count version of
541 * altos-xdep.c, arm-xdep.c, coffread.c, command.c, convex-xdep.c,
542 core.c, dwarfread.c, gould-xdep.c, infcmd.c, language.c,
543 m88k-xdep.c, main.c, printcmd.c, pyr-xdep.c, source.c,
544 sun386-xdep.c, symm-xdep.c, umax-xdep.c, values.c, xcoffread.c:
545 Change all instances of use of fixed args concat() to variable
546 args concat() now located in libiberty.
548 Tue Nov 12 07:23:46 1991 John Gilmore (gnu at cygnus.com)
550 * Makefile.in: Add xcoffread.c, xcoffexec.c.
551 * xcoffread.c: New file for handling AIX mangled-coff files.
552 * xconfig/rs6000, tconfig/rs6000: New files.
553 * buildsym.c: Add hooks for xcoffread.c.
554 * rs6000-pinsn.c, rs6000-tdep.c, rs6000-xdep.c, tm-rs6000.h,
555 xm-rs6000.h, rs6k-opcode.def, rs6k-opcode.h: New files.
556 * xcoffexec.c: New file for handling AIX shared libraries.
558 Mon Nov 11 19:14:31 1991 Fred Fish (fnf at cygnus.com)
560 * core.c: Minor rewording of message to user containing name of
561 (and possibly arguments to) the program that generated a core
564 * elfread.c: Remove the register_addr() stub now that it is no
567 * procfs.c: Move misplaced #endif for ATTACH_DETACH. Add new
568 fetch_core_registers() function for core file support.
570 Sat Nov 9 13:37:57 1991 Fred Fish (fnf at cygnus.com)
572 * dwarfread.c (dwarf_psymtab_to_symtab): Remove leftover call
573 to do_cleanups() which resulted from a previous change.
575 * elfread.c: Re-enable compilation of register_addr() stub
576 whenever it is not supplied by coredep.c
578 Sat Nov 9 00:40:32 1991 John Gilmore (gnu at cygnus.com)
580 Add tracking of object files (that contain symbols) to gdb.
581 This includes a "struct objfile" that owns symtabs and psymtabs
582 that were read in from that binary file.
584 * symfile.h: Add struct objfile. Add pointer to the objfile
585 into the struct sym_fns.
586 Replace global `symfile' and `symfile_mtime' with
587 `symfile_objfile'. Add global object_files chain.
589 * symfile.c: Move param.h above symtab.h.
590 (sort_misc_function_vector): Add.
591 (syms_from_objfile): Was syms_from_bfd.
592 (symfile_open): Now returns objfile.
593 (allocate_objfile): New.
594 (free_objfile): New, replacing free_all_.*symtabs.
595 (symfile_init): Takes objfile arg, puts it in sym_fns result.

597 (allocate_symtab): Takes objfile as new parameter, chains them.
598 Handle INIT_EXTRA_SYMTAB_INFO.

601 * dbxread.c: Make more errors into complaints.
602 (push_subfile, pop_subfile): Move to buildsym.c.
603 (dbx_symfile_read, dbx_symfile_init, fill_symbuf, read_dbx_symtab,
604 start_psymtab, psymtab_to_symtab_1, read_ofile_symtab,
605 dbx_psymtab_to_symtab, ): Use bfd ops, don't use file descriptor.
606 Pass objfile. Change callers.
607 (fill_symbuf, SWAP_SYMBOL): Take bfd as arg.
608 (read_dbx_symtab): Just wipe out new symbols, not all, on error.
609 (end_psymtab): Blow away psymtab if empty.
610 (process_symbol_pair): Swallow into read_ofile_symtab.

614 * buildsym.c (end_symtab): Pass objfile.
615 (dbx_lookup_type): Handle null typevector.
616 (dbx_alloc_type): Check file number, not sym number, for -1.
617 (find_symbol_in_list): Add for xcoffread.
618 (start_symtab): Default typevector is empty. Keep reusing same
620 (end_symtab): Take objfile argument and pass it to
621 allocate_symtab. Don't make a symtab if no blocks or symbols.
622 Handle empty typevector.
623 (push_context): New function for context stack nesting.
624 (read_type): Mark FIXME where we need to reintroduce type smashing.
626 * buildsym.h (pop_context): Macro, paired with push_context.
627 (subfile_stack): Move here from dbxread.c.
629 * coffread.c (end_symtab, read_coff_symtab): Take and use objfile arg.
630 (read_coff_symtab): Cleanup by freeing objfile, not all symtabs.
632 * mipsread.c (read_mips_symtab, parse_partial_symbols, parse_fdr,
633 new_psymtab, new_symtab): Take and use objfile arg.
635 * dwarfread.c (scan_compilation_units, start_psymtab,
636 process_dies, end_symtab, dwarf_build_psymtabs,
637 read_lexical_block_scope, read_func_scope, read_file_scope): Take
638 and use objfile argument.
639 (psymtab_to_symtab_1, read_ofile_symtab): Don't take or use file
640 descriptor. Use BFD internal functions instead.
641 (end_symtab): Call global allocate_symtab.
643 * elfread.c, target.c: Minor changes to accommodate objfiles.
644 * symtab.h: partial_symbol_table has no symfile_name member now.
645 (fn_fieldlists voffset): avoid non-int bitfield.
646 (struct symtab): Add objfile * and objfile_chain * of symtabs.
647 (struct partial_symtab): Add objfile * and objfile_chain * of
648 psymtabs. Remove symfile_name.
650 * symmisc.c: Lose free_all_symtabs, free_all_psymtabs.
651 (printsyms_command): Rename from print_symtabs. Add selective
652 listing if 2nd argument given. Print objfile info.
653 (printpsyms_command): Rename from print_partial_symtabs. Ditto all.
654 (printobjfiles_command): New; prints objfiles lists, and checks

662 * defs.h (warning_setup, warning): Declare.
663 * expprint.c (print_subexp, UNOP_MEMVAL case): Lint.
664 * inflow.c (new_tty): Use USE_O_NOCTTY #define.
665 * language.c, printcmd.c (print_scalar_formatted), signame.c,
668 Thu Nov 7 18:26:15 1991 Steve Chamberlain (sac at rtl.cygnus.com)
670 * Makefile.in: link with libiberty after libreadline, since
671 readline might want something in libiberty.
672 * m88k-xdep.c: Fixed the register offsets in the ptrace_user
673 struct for BCS 88k machines.
674 * xm-m88k.h: don't define USIZE if already defined.
675 * configure.in: Added delta88 target.
677 Thu Nov 7 04:51:19 1991 John Gilmore (gnu at cygnus.com)
679 * am29k-pinsn.c, am29k-opcode.h: Fix decoding of mtacc, dmac, fmac.
681 * tm-*.h: Remove READ_DBX_FORMAT, COFF_FORMAT, and
682 READ_MIPS_FORMAT, which have been unused since BFD. Still
683 remaining is COFF_NO_LONG_FILE_NAMES.
684 * tm-sun3.h, tm-altos.h: Remove detritus accidentally left from
685 function calling code moved to m68k-tdep.c.
687 Wed Nov 6 17:21:59 1991 John Gilmore (gnu at cygnus.com)
689 * coffread.c: Eliminate c_nsyms in favor of c_naux.
690 Complain if no auxents on .bf and .ef FCN symbols, and assume
691 lots of line numbers.
692 (init_linenos, enter_linenos): Use a sentinel at the end of the
693 read-in linenos, to make for a fast, safe loop-end test.
695 Wed Nov 6 02:54:08 1991 Steve Chamberlain (sac at cygnus.com)
697 * coffread.c (read_coff_symtab): coffread used to rely on the
698 x_sym.x_misc.x_lnsz.x_lnno field giving the # of linnos in a
699 function. Two of the formats I'm using (29k and 88k) don't seem to
700 set it. Ths patch to fcn_last_line and (enter_linenos) is an
701 attempt to use the actual size of the linno table in the file to set
702 the number of linenos to process.
704 Tue Nov 5 22:47:46 1991 Steve Chamberlain (sac at cygnus.com)
706 * Makefile.in: put a - infront of the mv y.tab.c c-exp.tab.c and
707 mv y.tab.c m2-exp.tab.c, so that if bison is used, and the files
708 are created in place, so the mv fails, then the make continues.
710 Tue Nov 5 16:47:47 1991 Per Bothner (bothner at cygnus.com)
712 Add C++ as a separate language.
713 * defs.h (enum language): Add language_cplus.
714 * dwarfread.c (end_symtab): Support language_cplus.
715 * c-exp.y: Add new struct language_defn cplus_language_defn.
716 Don't set c to be the default language (see main.c).
717 * c-exp.y (yylex): Only look for field of this if
718 language is C++. (First difference from C!)
719 * language.c: Add case branches for C++ (currently, all
720 the same as C). Also, add c++ to "usage" note for "set lang".
721 * valprint.c (typedef_print). Add case branches for C++.
722 * main.c (main): New way to set initial language: Look at
723 file extension of psymtab containing main(). (Same as we
724 do for symtabs, but avoid loading the symtab yet.)
725 * symtab.c: New routine find_main_psymtab(), used by main()
726 to set initial language.
727 * symfile.c (allocate_symtab): Move code for mapping file
728 extensions-> languages to new deduce_language_from_filename().
730 Fix a C++ problem when looking for methods in super-classes.
731 There was confusion between base and derived types.
732 * valops.c (value_fn_field): Change function interface.
733 * values.c: Use new value_fn_field interface.
735 Mon Nov 4 10:49:33 1991 Per Bothner (bothner at cygnus.com)
737 * infrun.c: Fixed typo in comment.
738 * utils.c: All the v*fprintf emulation is now in libiberty,
739 so we can get rid of some junk.
740 * xm-sun3os4.h, xm-sun4os4.h, xconfig/decstation, xconfig/i386sco,
741 xconfig/sun3os4, xconfig/sun4os4: Don`t need HAVE_STRSTR any more.
742 * m68k-pinsn.c (print_insn_arg): Support BB/BW/BL
743 type operands, as used by branch instructions.
744 * gmalloc.c: Fix prototype of memcpy.
745 * elfread.c: Comment out register_addr, since it conflicts
746 with the one in coredep.c.
747 * buildsym.h: Remove extern declarations of two functions
748 that are really static in buildsym.c.
749 * tm-mips.h: Add symbolic names for more registers.
750 * mips-xdep.c (store_inferior_registers): Use new register names.
751 * xm-mips.h: Simplify REGISTER_U_ADDR, since it is now
752 only used for core files, not ptrace. Therefore,
753 the KERNEL_U_ADDR hack is no longer needed.
754 The mapping to ptrace number is now in in mips-xdep.c.
755 * mips-xdep.c: Define REGISTER_PTRACE_ADDR (using the
756 mapping from the old REGISTER_U_ADDR), and use it
757 in {fetch,store}_inferior_registers.
758 * mipsread.c: Rename #include ecoff.h to new name coff-mips.h.
759 * mips-tdep.c (mips_push_dummy_frame, mips_pop_frame):
760 Save/restore FP regs correctly (?).
761 * dbxread.c: Remove duplicate define_symbol and type_synonym_name
762 (these had been previously moved to buildsym.c).
763 Hence, define_symbol becomes extern instead of static.
764 * buildsym.c (read_struct_type): Comment out bogus handling
765 of C++ operator methods. Minor hacking of reading of class
766 contexts. Make define_symbol non-static, so dbxread.c can call it.
768 Fri Nov 1 11:05:47 1991 John Gilmore (gnu at cygnus.com)
770 * mipsread.c (read_mips_symtab, read_the_mips_symtab): Use real
771 filename with error messages.
772 * stack.c (frame_select_command): Rename to select_frame_command
773 to avoid "fr" and "fra" having nonunique completions.
774 * symfile.c (sort_symtab_syms): Ignore sort of zero symtab *.
775 (symfile_init): Print file format name when unable to handle it.
776 (free_named_symtabs): Use BLOCKVECTOR rather than obsolete BLOCKLIST.
777 * symmisc.c (free_symtab): Only free linetable if nonzero.
778 * symtab.h: Remove obsolete BLOCKLIST macros.
780 Thu Oct 31 18:12:43 1991 Stu Grossman (grossman at cygnus.com)
782 * infrun.c (wait_for_inferior): another stepi/nexti fix. Ensure
783 that stop_step is 1 at bottom of main loop. I don't know why this
784 needs to be done, but it helps me sleep better at night.
786 Sun Oct 27 18:18:39 1991 Stu Grossman (grossman at cygnus.com)
788 * main.c (initialize_history): Read history after reading all
791 Sun Oct 27 14:09:25 1991 John Gilmore (gnu at cygnus.com)
793 * buildsym.c: Break out initial malloc sizes.
794 (record_line): Record directly in a subfile. Alloc on demand.
795 (compare_line_numbers): Add from xcoffread.c.
796 (end_symtab): New params say whether to sort pendings and
797 linetable. Patch block stabs if defined. Shrink linetable before
798 allocating the symtab.
799 * buildsym.h: Delete line_vector* and prev_line_number. Add
800 global_stabs and file_stabs for xcoffread.
801 * dbxread.c (start_subfile): Move to buildsym. Change above calls.
802 * symtab.h: LINETABLE(symtab) can now be null. Zap LINELIST.
803 * symmisc.c, symtab.c: Cope with null LINETABLEs.
805 * blockframe.c: Pass fromleaf to INIT_EXTRA_FRAME_INFO.
806 * tm-29k.h, tm-88k.h, tm-i960.h, tm-irix3.h, tm-mips.h, tm-pyr.h,
807 tm-sparc.h: Accept fromleaf parameter.
808 * c-exp.y (yyerror): Pass error message if given.
809 * configure.in: Add rs6000 host and target.
810 * inflow.c (new_tty): O_NOCTTY kludge for RS/6000.
811 * symfile.h (entry_point): Add.
813 Sat Oct 26 00:16:32 1991 John Gilmore (gnu at cygus.com)
815 * buildsym.c: New file. Breaks out symbol-table-building routines
816 from dbxread.c, so they can be shared with xcoffread.c.
817 * buildsym.h: New file. Declarations for buildsym.c users.
818 * dbxread.c: Remove large chunks into buildsym.c.
819 * Makefile.in: Add buildsym.c and buildsym.h.
821 * symfile.c (syms_from_bfd): New routine.
822 (add_symbol_file): Call it to do the real work.
823 (syms_from_bfd): Initialize entry_point before calling symfile_init.
824 * symtab.h, symfile.c, coffread.c, mipsread.c, dwarfread.c:
825 Avoid declaring or setting entry_point (symfile.h & symfile.c cope).
827 Fri Oct 25 10:58:16 1991 Mark Eichin (eichin at cygnus.com)
829 * cplus-dem.c (cplus-demangle): added support for templates, static
830 data, and the new (correct) mangling for destructors.
832 * dwarfread.c: (dwarfwarn): created a varargs version of
833 dwarfwarn, for non __STDC__ compilers.
835 * c-exp.y: (yylex): added match for "template" token.
836 (typebase): added TEMPLATE name '<' type '>' clause, for explicit
837 specification of template types.
839 * symtab.c: (lookup_template_type): new function for finding
840 templates in symbol table.
841 (type_name_no_tag): changed to explicitly check for s/u/e at the
842 beginning of the symbol - if it is a template, none of these will
843 be there (but the name will still contain spaces.)
845 Fri Oct 25 18:59:32 1991 Per Bothner (bothner at cygnus.com)
847 Various fixes to improve g++ debugging.
848 * symtab.h: Add is_const and is_volatile flags for each method.
849 These are bit fields - take their space from voffset,
850 which shrinks to 30 bits. Since voffset is now a bitfield,
851 make it unsigned for portability. This changes its interpretation
852 slightly: Static methods now have voffset 1 instead of -1,
853 and virtual offsets start at 2, not 1.
854 * symtab.c: Renamed gdb_mangle_typename to gdb_mangle_name,
855 since it now returns an entire magled method name, not just
856 the type part. This avoids some duplication.
857 It also allows us to correctly mangle const and volatile
858 methods (using the new is_const and is_volatile bit fields
860 * valprint.c (type_print_base), values.c (check_stub_method):
861 Simplify by using new gdb_mangle_name.
862 * values.c (value_headof): Fix to correctly handle single
863 inheritance (actually two fixes, either of which suffices).
864 * dbxread.c (read_struct_type): Handle const and volatile
866 * dbxread.c (read_struct_type): Yet one more place where
867 we must handle '\\' continuations.
868 * valprint.c (vtbl_ptr_name): Add final '\0'.
870 Fri Oct 25 16:06:38 1991 Stu Grossman (grossman at cygnus.com)
872 * tm-sparc.h, tm-68k.h (EXTRACT_RETURN_VALUE): fix output of
873 short return values for sparc and 68k. Patch from Paul Eggert.
875 * coffread.c, coredep.c, i386-xdep.c: install patches for
876 SysV/386 3.2 from Mauro DePalma.
878 Fri Oct 25 02:02:13 1991 John Gilmore (gnu at cygnus.com)
880 * core.c (core_file_info), exec.c (exec_file_info): Print file
881 type. Use printf_filtered.
883 * valops.c (value_fetch_lazy): Avoid 0-length fetches.
885 Thu Oct 24 23:06:40 1991 Fred Fish (fnf at cygnus.com)
887 * dwarfread.c: Add casts to remove compiler warnings.
889 * tm-3b1.h, tm-68k.h, tm-altos.h, tm-amix.h, tm-hp300bsd.h,
890 tm-hp300hpux.h, tm-isi.h, tm-news.h, tm-pn.h, tm-sun2.h,
891 tm-sun3.h: Remove locally duplicated code for calling functions
892 in the inferior. The only differences were in the specific trap
893 vectors used and whether or not an fpu was present. These are
894 now handled by appropriate definitions of BPT_VECTOR and
895 HAVE_68881 respectively. Other minor obvious cleanups.
897 * valops.c: Correct a minor misspelling.
899 * utils.c: Remove local BSD/USG hacks that are now in libiberty.
901 * dwarfread.c: Remove prototype for dwarfwarn. Does not work
904 Thu Oct 24 09:33:44 1991 John Gilmore (gnu at cygnus.com)
906 * stack.c (frame_command): Always print. Use new
907 frame_select_command to select a frame without printing.
909 * dwarfread.c: Use <varargs.h>, since <stdarg.h> is not portable.
911 Thu Oct 24 01:32:51 1991 Fred Fish (fnf at cygnus.com)
913 * dwarfread.c: New file for DWARF debugging format support.
915 * elfread.c: New file for ELF object file format support.
917 * procfs.c: New file for SVR4 /proc (process file system) support.
919 * tm-amix.h, xm-amix.h, tconfig/amix, xconfig/amix: New files for
922 * xm-svr4.h, tm-svr4.h: New files for SVR4 support.
924 * xm-m68k.h: New file for host machines with m68k cpu.
926 * Makefile.in: Add elfread.c and dwarfread.c to SFILES_MAINDIR.
927 Add elfread.o and dwarfread.o to OBS.
929 * symfile.h: Add "elf" to list of supported formats in comment.
931 * c-exp.y, defs.h, symtab.h, valprint.c: Add three new builtin
932 types to gdb, builtin_type_long_double, builtin_type_complex, and
933 builtin_type_double_complex. Add and use new TARGET_SHORT_BIT,
934 TARGET_INT_BIT, TARGET_LONG_BIT, TARGET_FLOAT_BIT,
935 TARGET_DOUBLE_BIT, TARGET_LONG_DOUBLE_BIT, TARGET_COMPLEX_BIT, and
936 TARGET_DOUBLE_COMPLEX_BIT, as the sizes in bits of the indicated
937 types on the target machine (ala the existing TARGET_LONG_LONG_BIT).
939 * infrun.c: When using SVR4 /proc interface instead of ptrace(),
940 call proc_set_exec_trap() to setup child to stop at first instruction.
942 * inftarg.c: When using SVR4 /proc interface, call proc_wait()
945 * m68k-tdep.c: Add new routines supply_gregset(), fill_gregset(),
946 supply_fpregset(), and fill_fpregset(), which are machine
947 dependent support routines for SVR4 /proc interface.
949 * utils.c: Add warning_setup() and warning(). Warning() behaves
950 the same as error() except that it returns normally rather than
951 jumping back to command level. Modules that don't want to call
952 warning() for some reason, but want to produce their own warnings,
953 can call warning_setup() to ensure compatibility with the way
954 warning() and error() deal with the terminal.
956 * symtab.c: Make internal errors produce more useful messages.
958 * tm-68k.h: Move code that is duplicated in almost every single
959 m68k based machine's configuration files to this common file.
960 Duplications in the configuration files still need to be removed
963 * infrun.c (child_create_inferior): System V versions must call
964 setpgrp() with no arguments, to comply with prototyping typically
967 * munch: Add support for SVR4 style nm output.
969 * dbxread.c, mipsread.c symmisc.c, symtab.c: Remove the object
970 file specific fields from the partial symbol table structure and
971 replace them with a pointer to private data for each different
972 flavor of object file reader to initialize appropriately.
974 Wed Oct 23 09:38:20 1991 John Gilmore (gnu at cygnus.com)
976 * xconfig/sun[34]os4: Add note about strstr botch on sunos4.0.3c
979 * mipsread.c (fixup_undef_type): New function. If a struct /
980 union / enum is defined in a header file but nowhere else used,
981 (by typedefing, pointer referencing or declaration) the mipsread code
982 builds the complete tree for the structure but leaves its code as
983 TYPE_CODE_UNDEF as it doesn't know what kind of aggregate it is.
984 Guess its type based on the details of the members.

1096 This avoids coredumps under `set print object on' in value_headof
1097 (called erroneously by value_from_vtable_info) for `p &struct'
1098 or `p *struct'. From Peter Schauer.
1100 Mon Oct 7 00:06:52 1991 John Gilmore (gnu at cygnus.com)
1102 * Makefile.in: Roll version to 4.1.2.
1103 * dbxread.c: Use aout64.h, not a.out.gnu.h. Get external symbol entry
1104 size from BFD (but, FIXME, we don't yet read external nlists's and
1105 convert them to internal nlists's before handling them -- we still
1106 assume they have the same size and alignment.) Use SET_NAMESTRING
1108 * exec.c (exec_file_command): Move dead coff-encapsulation code
1110 * m88k-tdep.c, m88k-xdep.c: Remove encap test and #inc <a.out.h>.

1120 * mips-xdep.c (store_inferior_registers): Don't try to
1121 write the (pseudo) FP.
1122 * mipsread.c (parse_partial_symbols): Improved algorithm for
1123 setting pst->texthigh.
1125 Fri Oct 4 16:47:32 1991 Roland H. Pesch (pesch at cygnus.com)
1127 * doc/Makefile: make TEXINPUTS include . everywhere
1129 Fri Oct 4 00:35:56 1991 John Gilmore (gnu at cygnus.com)
1131 * coffread.c, dbxread.c, symfile.c, symmisc.c, symtab.h: Remove
1132 vestiges of typevectors, which were for symsegs and are no longer
1133 used. (From a question by Eliot Dresselhaus
1134 <dresselh@RFT30.nas.nasa.gov>).
1136 Thu Oct 3 09:33:26 1991 John Gilmore (gnu at cygnus.com)
1138 * dbxread.c, coffread.c: static-ize functions that were
1139 gratuitiously external. (From Fred Fish.)
1141 * c-exp.y: sym->class to SYMBOL_CLASS (sym).
1143 * dbxread.c (dbx_lookup_type): Keep doubling size of typevector
1144 until it is large enough.
1146 * dbxread.c (read_type): Handle error case slightly better.
1147 Make complaint message not C++-specific.
1149 Wed Oct 2 17:21:07 1991 Stu Grossman (grossman at cygnus.com)
1151 * infrun.c (wait_for_inferior): Fix step/next so that you only
1152 stop at the beginning of a new line. This fixes various problems
1153 with for loops, nested if-else's and switch statements.
1155 Tue Oct 1 06:33:55 1991 John Gilmore (gnu at cygnus.com)
1157 * symtab.c (lookup_symtab_1, lookup_symbol): "fatal" errors
1158 between symtabs and psymtabs become ordinary error()s.
1160 * dbxread.c (read_dbx_symtab): Relocate end_of_text_addr
1161 properly, making "end pc" correct in shared lib psymtabs.
1162 (From Guy Harris <guy@auspex.com>.)
1164 Mon Sep 30 13:15:31 1991 John Gilmore (gnu at cygnus.com)
1166 * dbxread.c: Enable, but soften, const_vol_complaint.
1167 (read_dbx_symtab): N_STSYM and N_LCSYM define static vars.
1168 Ditto Gould N_NBSTS and N_NBLCS. Also, all types in the psymtab
1169 should be file-scope, not global.
1170 (read_struct_type): Remove ancient multiple-inheritance warning.
1171 (read_range_type): Check base type, complain & patch if undefined.
1172 * stack.c (frame_info): Demangle the function name in `info stack'.
1173 (From Peter Schauer)
1175 Sat Sep 28 10:02:33 1991 John Gilmore (gnu at cygnus.com)
1177 * eval.c (evaluate_subexp_for_address): Don't use
1178 TYPE_POINTER_TYPE directly (it might be zero if this type has
1179 never had a pointer created before); use lookup_pointer_type.
1180 * symtab.c (lookup_method_type): Arguments were swapped in all
1181 callers, so fix it here. I'm amazed this worked at all!
1183 Fri Sep 27 18:09:31 1991 John Gilmore (gnu at cygnus.com)
1185 * c-exp.y, m2-exp.y: Define more yysymbols that happen to be
1186 "bss" rather than "data" symbols, but which still conflict.
1189 * coffread.c (coff_symfile_read): Use xmalloc, not malloc.
1190 * core.c (core_files_info): Shorten output.
1191 * exec.c (exec_files_info): Ditto.
1192 (build_section_table): Ignore zero-length sections.
1193 * language.c, printcmd.c: Lint.
1194 * language.h (get_frame_language): Declare.
1195 * saber.suppress: update.
1196 * stack.c (find_relative_frame): Remove complex code that was
1197 #if 0'd, stick with simple code. Lint.

1206 * nindy-tdep.c (nindy_frame_chain_valid): Use lookup_misc_func.
1207 (Reported by Mark Peek <mark@imagen.com>.)
1209 * solib.c (solib_map_sections): Relocate all sections, even
1210 though only the text section's size is tracked. Mark ld_text
1211 for eventual elimination as we generalize to N sections.
1213 * infrun.c (wait_for_inferior): Don't check if the PC is in a
1214 call_dummy if we were stopped by a random signal that is being
1215 passed to the program. This produced wierd results when calling
1216 functions in the inferior and signals (e.g. SIGALRM) were in use.
1218 Tue Sep 24 18:05:30 1991 John Gilmore (gnu at cygnus.com)
1220 * infrun.c (IN_SIGTRAMP): Not parenthesized properly.
1221 Bugfix from Paul Eggert <eggert@twinsun.com>.

1237 * language.c (set_language_command): Print useful help message,
1238 and restore the language string after giving help.
1239 * valprint.c (typedef_print): Print typedef in C or M2.
1240 * symtab.c (list_symbols): Use it.
1241 * main.c (main): Avoid any output before (gdb) prompt when -q.
1242 * language.c (set_language_command): Handle errors by restoring
1243 the language string to its current state (fix from A. Beers).

1245 "how to install" and "how to print the doc" stuff so it drops
1247 * configure.in: Rename rtpc CPU to romp to match config.sub.
1248 * README, WHATS.NEW, TODO: Update for gdb-4.1.

1253 autoloading shared libs, copyright etc on GDB startup, clean up $_
1254 and $__ index refs, set/show listsize and related updates to list
1255 cmd. New host/target configs.
1257 Fri Sep 20 15:46:00 1991 Roland H. Pesch (pesch at cygnus.com)
1259 * doc/Makefile: generate aux version-no file doc/gdbVN.m4
1260 from main Makefile.in version definition
1261 doc/gdb.texinfo: use version recorded in doc/gdbVN.m4 for current
1263 Makefile.in (setup-to-dist): generate doc/gdbVN.m4
1265 * doc/gdb.texinfo: merge new language-switching and lang-specific
1268 Fri Sep 20 15:00:57 1991 Per Bothner (bothner at cygnus.com)
1270 * mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
1271 compilers (which may lack stddef.h).
1273 Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com)
1275 * dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and
1276 N_WARNING are the same except for the N_EXT bit, so just use their
1277 values alone, rather than OR-ing them with N_EXT.
1279 Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com)
1281 * mipsread.c (parse_lines): Deal with negative extended line
1284 * c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid
1285 global symbol conflicts.
1287 Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
1289 * .gdbinit: Move 'set complaints' to top, so it runs even in
1290 case we aren't debugging GDB.
1291 * language.c (_initialize_language): Fix type check and range
1292 check documentation strings.
1293 * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
1294 language.c can use it. (Though language.c should really not be
1295 handling warnings/errors the way it does, FIXME.)
1296 * symtab.c (lookup_primitive_type): const lint.
1298 Bugfix from Peter Schauer:
1299 * source.c (lines_to_list): Make signed, to avoid comparison
1300 going unsigned and complaining that -3 is too high for 21 lines.
1301 * stack.c (lines_to_list): Ditto.
1303 Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
1305 * Makefile.in (HFILES): Add minimon.h.
1306 (VERSION): Roll version number to 4.0.95.
1307 (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
1308 New rules for building distributions. Normal distribution
1309 is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
1310 one level up from here; it calls make-proto-gdb.dir to build a
1311 directory `proto-gdb' which is an image of the release. The old
1312 `gdb.tar.Z' rule still works too.
1313 * config.sub, configure: Roll in latest from ..
1315 Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
1317 * doc/gdbint.texinfo: Reorder contents; reorganize new-host,

1323 Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
1324 * mipsread.c (parse_partial_symbols): Enter the name of all
1325 structs/unions... into the psymtab so we can access them if the
1326 symtab is not read in.
1327 * mips-tdep.c: Remove some unneeded #includes.
1328 * xconfig/dec3100: Add HAVE_STRSTR.
1330 Thu Sep 19 15:14:23 1991 John Gilmore (gnu at cygnus.com)
1332 * Makefile.in: Circumvent Sun Make bug on *-exp.tab.o.
1333 * c-exp.y, m2-exp.y: Lint.

1336 * mipsread.c (_initialize_mipsread): Avoid using
1337 builtin_type_void at initialize time.

1342 Merge multiple-language support, and partial Modula-2 support,
1343 from Andrew Beers <beers@cs.buffalo.edu>.

1439 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
1441 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
1442 entries are enclosed herein. Not all of these changes
1443 have been merged into the master GDB sources -- check the
1444 ChangeLog above here for the merge log.
1446 Mon Jun 3 17:05:45 EDT 1991
1448 m2-exp.y Created. Tested outside of GDB for a few days. Proper
1449 operators were added, C specific operators and tokens
1450 removed. yylex() revamped to some extent. Still things
1451 missing from the grammar, such as sets.
1452 Tested for two weeks in GDB v3.5.
1454 Tue Jun 11 17:23:48 EDT 1991
1456 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
1457 so they are built-in. Sort of a hack.
1459 Fri Jun 14 12:53:51 EDT 1991
1461 m2-exp.y Added range checking for numeric constants. Any numeric
1462 constant is assumed to be of builtin type INTEGER unless:
1463 (1) it is octal or hexadecimal, in which case it is a
1464 CARDINAL; (2) it is too big to fit into an INTEGER, in
1465 which case it is a CARDINAL.
1466 eval.c Added simple range checking for +, -, and * on integers.
1467 Doesn't work very well for *, since 6 * 1,000,000,000 =
1468 1,705,032,704, which fails the simple test of result >=
1469 first_operand, no matter in what order the operands are.
1471 Tue Jun 18 14:11:30 EDT 1991
1473 Broke the parser into parts, one containing the C grammar and the other
1474 containing code to be shared by all of the grammars.
1476 The following files no longer exist:
1481 The following files were added:
1483 c-exp.y (The C grammar)
1484 m2-exp.y (The Modula-2 grammar)
1485 parser-code.c (Code that is shared by the above grammar)
1489 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
1490 now necessary to use the Bison compiler compiler, since it
1491 will generate function/variable prefixes other than yy.
1493 Tue Jun 18 16:47:49 EDT 1991
1495 symtab.[ch] Added the external variable working_lang, than holds the
1496 value of the current working language.
1497 Added the ennumerated type language_mode, with the values
1498 language_auto and language_manual, the former meaning that
1499 GDB sets working_lang as needed, and the latter meaning
1500 that the value of working_lang is totally under user
1502 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
1503 REAL, BOOLEAN and CHAR. Also added the type codes
1504 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
1505 utils.c Added set_language_command and show_language_command to
1506 implement the GDB support commands "set language" and
1508 expression.h A number of identifiers were added to the type exp_opcode
1509 to facilitate Modula-2 builtin functions, integer
1510 division, and array indexing.
1512 Wed Jun 19 13:25:58 EDT 1991
1514 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
1515 if the language specified by working_lang requires the use
1516 of strict typing of expressions. Eventually, even this
1517 will be able to be changed by the user.
1518 Added the macro RANGE_CHECK, which evaluates to non-zero
1519 if the language specified by working_lang requires the
1520 checking of a value against the domain of its type.
1521 Eventually, even this will be able to be changed by the
1523 language.[ch] Predicates involving types (simple_type, ordered_type,
1524 same_type, integral_type, numeric_type, character_type,
1525 boolean_type, float_type) are added. These predicates are
1526 based on the current value of working_lang, and are handy
1529 Wed Jun 19 15:39:34 EDT 1991
1531 eval.c Added the function type_array_rank which computes the rank
1533 valarith.c Added the funtion value_bool, which when given a integer
1534 value.h value (ie. struct value *) as an argument, it returns a
1535 boolean value (ie. struct value *) true if that integer
1536 is non-zero, and a boolean value false otherwise.
1537 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
1538 will print out properly.
1540 Wed Jun 19 16:36:34 EDT 1991
1542 valops.c Added the function value_capitalize, which returns it
1543 value.h argument capitalized if its argument is a lowercase
1544 letter, or the argument unchanged if its argument is not a
1546 valarith.c Added the function range_check_p, which returns non-zero
1547 value.h if its value argument is between the integral bounds upper
1549 Added the function range_check_enum_p, which makes sure
1550 that its value argument is a valid member of the domain of
1552 Added the function range_check_range_p, which makes sure
1553 its value argument lies between the upper and lower bounds
1554 of its type argument, which must be a ranged type.
1555 Added the function check_array_index, which range and type
1556 checks an index of an array.
1557 Added the function value_multi_subscript, which computes
1558 array[idx1,idx2...idxN], given a value array and an array
1559 of values representing indicies.
1560 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
1561 unpack_long to work with TYPE_CODE_BOOL and
1564 Wed Jun 19 18:04:08 EDT 1991
1566 symtab.c Stored pervasive types in a structure and make
1567 lookup_pervasive_type() a lookup function that was based
1568 on working_lang. If lookup_pervasive_type() returned
1569 non-zero, then that value was returned (a fix, since
1570 before it simply wouldn't return the pervasive type.)
1571 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
1572 non-zero if the language specified by working_lang means
1573 "conversion" when it says "cast".
1574 valops.c Added the function value_real_cast(), which performs a
1575 value.h *cast*, not a *conversion*, which is what value_cast()
1576 does when it can. In particular,
1577 value_cast(<float_type>,4) = 4.0, while
1578 value_real_cast(<float_type>,4) = some mess.
1579 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
1580 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
1581 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
1582 and MIN on integral types. *NOTE*: These are currently
1583 hardcoded to work only if there are 8 bits per storage
1585 eval.c Made logical functions call value_bool to return a
1586 properly typed boolean value, based on working_lang.
1588 Thu Jun 20 11:55:27 EDT 1991
1590 valprint.c Types now print out in a Modula-2 fashion. This works for
1591 the cases when the type is printed out step-by-step, that
1592 is, it doesn't work when the name of a structured type
1593 (which includes the keyword "struct", etc.) is simply
1595 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
1596 since type specifications in C and Modula-2 are very
1597 different. The C printing of a type is very recursive,
1598 whereas in Modula-2 it is generally very simple. C has
1599 type prefixes and suffixes, which have no real analogue in
1600 Modula-2. Maybe type_print() should call a language
1601 specific type printer. This is also advantageous if we
1602 compile GDB to exclude some of the languages. We'll just
1603 leave those functions out.
1605 Thu Jun 20 16:57:10 EDT 1991
1607 dbxread.c When reading the complete symbol table in (via
1608 psymtab_to_symtab()), the number and types of function
1609 arguments are added to a function type. define_symbol()
1610 calls add_param_to_type() to accomplish this.
1611 Assumption: when we come across a function definition
1612 (N_FUN symbol with an 'f' or 'F' in the name), its
1613 arguments will appear before another function definition.
1614 When a function is found, a pointer to its type is placed
1615 in the global in_function_type. Changes that
1616 add_param_to_type() makes are to this global.
1617 valprint.c The type of a function now includes (for Modula-2) the
1618 types of its parameters.
1619 eval.c Type checking and a check for the proper number of
1620 arguments is now done for function calls. Not sure of the
1621 impact this has on C++ member function yet.
1623 Thu Jun 20 19:58:48 EDT 1991
1625 valprint.c Rewrote the type printer. Broke it into two language
1626 specific parts, adding the functions type_print_m2() and
1628 An unfortunate consequence is this: if you debugging a C
1629 program in Modula-2 mode (why?), info types does not work
1630 well with regular expressions, since the types are printed
1631 out in Modula-2 terminology, but stored in C terminology.
1632 language.[ch] Added the functions new_type_last(), type_keyword(), and
1633 type_sep() to aid in the printing of typedefs.
1634 symtab.c Made the printing of typedefs as language independent as
1635 possible through calls to new_type_last(), type_keyword(),
1638 Fri Jun 21 11:50:26 EDT 1991
1640 dbxread.c Check all incoming ennumerated types. If it looks like
1641 Modula-2's BOOLEAN type, then change the type_code of the
1642 type to TYPE_CODE_BOOL so we can process it as a boolean
1644 valprint.c Replaced some of the 0x%x with calls to sprintf and
1645 hexformat() in val_print().
1646 language.[ch] Added the function hex_to_string(), which converts its
1647 integral argument to a hexadecimal number (format is
1648 language based) and returns the result as a string.
1650 Mon Jun 24 12:25:07 EDT 1991
1652 valprint.c Some functions call type_print_1() directly, instead of
1653 value.h using type_print(), so they can specify where (column) to
1654 print things. Since type_print() takes care of language
1655 dependence, that needs to be called first. Added a
1656 parameter depth to type_print() (so it is now like
1657 type_print_1). Changed type_print to type_print_at, and
1658 made type_print a macro that passes a depth argument of
1660 symmisc.c Changed all calls to type_print_1 to calls to
1662 Makefile.dist Made it possible to build GDB for a specific set of
1663 depend languages. Do this by passing a definition for the macro
1664 LANGS to make. LANGS should be a string containing a
1665 space-separated list of language names (ie. LANGS="c m2").
1666 The default is to build all languages. Note that grammar
1667 files must follow the naming convention of <lang>-exp.y.
1668 gdb.lang This holds the current value of the LANGS macro. It is
1669 examined every time make is called, and is updated if
1671 eval.c Added #ifdef _LANG_<lang> to these files.
1672 expread.c Still need to add them to dbxread.c and coffread.c.
1680 Mon Jun 24 16:33:11 EDT 1991
1682 language.[ch] Added the functions hexformat_pre() and
1683 hex_to_string_pre(), which take a prefix argument to
1684 include in the format string. Thus, hexformat_pre("08") will
1685 return "0x08x" (if the working language is language_c).
1686 Made hexformat() and hex_to_string() calls to the above
1687 with "" as the prefix argument.
1689 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
1690 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
1691 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
1692 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
1693 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
1694 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
1695 valprint.c, vax-pinsn.c
1697 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
1698 calls to hexformat() and hex_to_string(). Format strings without
1699 the leading "0x" were ignored.
1701 depend Updated to take the above into account.
1704 Tue Jun 25 15:27:18 EDT 1991
1706 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
1707 and type_check_t to keep track of the current state of
1708 range and type checking.
1709 main.c Added the variables range_mode, range_check, type_mode,
1710 and type_check to record the current state of range and
1711 type checking. Added initialization code to main().
1712 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
1713 the above variables.
1716 Tue Jun 25 17:57:08 EDT 1991
1718 dbxread.c process_one_symbol() updates the variable (enum language)
1719 source_lang based on the extension of the filename
1720 contained in the N_SO sybmol that started this symtab.
1721 When end_symtab() is called, the value of source_lang is
1722 put into the language field.
1723 stack.c select_frame() sets working_lang (and possibly type_check
1724 and range_check) to the language field of the symtab
1725 associated with the frame that is selected if working_mode
1726 is language_auto. If working_mode is language_manual, a
1727 warning is printed and working_lang is not set.
1728 language.c Added the function set_type_range(), which sets the value of
1729 type_check and range_check (if their modes call for
1730 automatic setting) based on the current value of
1731 working_lang. A non-zero argument will cause the current
1732 settings to be output.
1735 Wed Jun 26 14:51:40 EDT 1991
1737 eval.c Added range checks on assignment.
1738 m2-exp.y Added the grammar for sets to the language. Currently,
1739 these do not do anything except print an error message.
1741 Wed Jun 26 17:01:04 EDT 1991
1743 m2-exp.y Added the ability for parse_number() to parse negative
1744 numbers. A global flag is set upon encountering a unary
1745 minus. This was done to make, for example, 1 parse as a
1746 CARDINAL, and not as an integer, per Wirth's examples in
1747 Programming in Modula-2 ed.4.
1748 valprint.c Added support for "set radix 2" by then setting
1749 output_format to 't'.
1750 eval.c Implemented range checking on subrange types. Added calls
1751 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
1752 Implemented MIN and MAX for ennumerated types. The
1753 minimum value of an ennumerated type is defined by Wirth
1754 as the first identifier, and the maximum as the last.
1755 m2-exp.y Made octal numbers ending with "B" be characters and those
1756 ending with "C" be numbers, per Wirth's book. (p. 34)
1758 Thu Jun 27 14:11:52 EDT 1991
1760 stack.c select_frame() now only sets working_lang, it does not
1761 notify the user. If working_mode is language_manual, then
1762 a warning is issued once.
1763 main.c At the end of each call to execute_command(), working_lang
1764 is checked against the local static (enum language)
1765 current. If they differ and working_mode is
1766 language_auto, the new settings of language, type and
1767 range checking are printed out.
1768 stack.c Modified frame_info() to include the language of the
1769 current frame in the output of "info frame".
1770 language.[ch] Added the function language_str() which returns the name
1771 of the current language.
1773 Fri Jun 28 15:33:14 EDT 1991
1775 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
1776 the language. INCL and DECL currently cause an error,
1777 since sets are not implemented yet. INC and DEC are
1778 implemented as PREINCREMENT/PREDECREMENT with one
1779 argument, and as ASSIGN_MODIFY with two arguments.
1780 eval.c Added type checking to the above cases.
1781 value.h Added not_lval_constant to the lval_type ennumerated type.
1782 not_lval_constant means that the value is a constant
1783 value; that is 3 or 'a' or TRUE, not as in a constant
1784 identifier. This is used to help coerce numbers such as 3
1785 to either signed or unsigned numbers.
1786 valops.c Added the function value_coerce_constants() which coerces
1787 constant integers as following: if one is a constant and
1788 the other is not, the constant's type is set to the type
1789 of the other argument. If both are constants and one is
1790 signed, the other is converted to a signed constant.
1792 Sat Jun 29 17:26:29 EDT 1991
1794 valarith.c Added a better range checker. It now checks range
1795 (successfully) on integral operations [+-] (signed and
1796 unsigned) for any C sized type. Still does not work well
1797 for multiplication.)
1798 int_in_size() returns an integer that is coerced to fit into
1799 specified number of bytes.
1801 Mon Jul 1 13:04:14 EDT 1991
1803 language.[ch] Added the function binop_result_type(), which returns the
1804 builtin (struct type *) type that would be the result of a
1805 binop on the two values V1 and V2.
1807 Wed Jul 3 19:22:53 EDT 1991
1809 source.c Extended source_info() to include the source language in
1810 the output from "info source".
1812 Fri Jul 5 13:48:52 EDT 1991
1814 utils.c Moved the support functions for the GDB set/show commands
1815 dealing with language into language.c.
1816 language.c Added the function language_info(), which displays info
1817 about the current working language, type and range check
1818 settings. Called via the GDB command "info language".
1819 Added an initialization routine _initialize_language(),
1820 that sets defaults for the language, type and range
1821 variables and sets up the new GDB commands.
1822 main.c Language setup moved to language.c.
1825 Mon Jul 8 10:10:22 EDT 1991
1827 valarith.c Debugged the range checker for arithmetic. Still does not
1828 work for multiplication very well.
1830 Mon Jul 8 12:40:37 EDT 1991
1832 language.[ch] Added the function value_true() which returns non-zero if
1833 its argument represents a boolean true value.
1834 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
1835 check the truth of an expression.
1837 Thu Jul 11 12:51:34 EDT 1991
1839 language.[ch] Added the predicate structured_type(), which returns
1840 non-zero if the argument is a structured type.
1841 Added the predicate pointer_type(), which returns non-zero
1842 if the argument is a pointer type.
1843 eval.c Added the ability to do addition and substraction on
1844 pointers and integers. This case simply bypasses the
1847 Thu Jul 11 14:41:42 EDT 1991
1850 Added the symbol N_DEFD (0x4a) which is a definition
1851 module dependency that is used by the GNU Modula-2
1852 compiler and the linker. It is not important to GDB,
1853 except that [dbx|coff|mips]read.c should ignore these
1856 Fri Jul 12 16:07:00 EDT 1991
1858 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
1859 0 in val_print(). Also added statements to the else part
1860 to coerce type (argument to val_print) to a pointer type
1861 if it is an "array of unspecified length".
1862 valops.c Added the function value_m2_string(), which returns a
1863 (value) value which is a constant string, whose type is
1864 (ARRAY [0..n] OF CHAR). The length field of the type
1865 structure is set to zero, so it will be interpreted as an
1866 "array of unspecified length".
1867 stack.c Moved the language/frame mismatch check to
1868 main.c:execute_command().
1869 main.c The working language is recorded each time
1870 execute_command() is executed. If working lang has
1871 changed during its execution, then the new
1872 language/type/range info is printed out for the user. If
1873 the working language does not match the language of the
1874 frame, a warning is issued.
1876 Sat Jul 13 16:16:39 EDT 1991
1878 eval.c Moved all the type-checking stuff for operators to
1879 language.[ch] language.c. This is so we can keep language-specific
1880 stuff (like for what type operators are defined) in
1882 language.[ch] Added the function binop_type_check(), which checks to see
1883 if its two (value) arguments are type-compatible with its
1884 opcode argument. The opcode should represent an operation
1885 involving an operator. Also added the macro function
1886 unop_type_check, which calls binop_type_check with a
1887 NULL second argument.
1888 expprint.c Added Modula-2 operators to the op_print_tab, so info
1889 expression.h break works correctly. Also added "op_string", which
1890 returns the string corresponding to the (enum exp_opcode)
1891 opcode that is its argument.
1894 Sat Jul 13 18:26:18 EDT 1991
1896 coffread.c Added code to record the type of function arguments with
1897 each paricular function. Code is very similar to that
1899 dbxread.c Moved add_param_to_type() to symtab.c
1900 symtab.[ch] Added function add_param_to_type() from dbxread.c
1902 *** NOTE: The above additions have not been tested.
1904 Mon Jul 15 12:50:47 EDT 1991
1906 langauge.[ch] Added the functions type_error and range_error, which work
1907 like error() except if the type/range mode is set to
1908 *_mode_warn, then they do not do a return_to_top_level(),
1909 but merely print a warning.
1910 Also changed [set|show]_[type|range]_command() to support
1911 the new "warn" feature.
1913 Thu Jul 18 17:50:54 EDT 1991
1915 mipsread.c Added code to record the type of function arguments with
1916 each particular function. Code is very similar to that
1919 *** NOTE: The above additions have not been tested.
1921 Fri Jul 19 11:19:10 EDT 1991
1923 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
1924 UMIN_OF_SIZE, which when given a size of a numeric type,
1925 return the maximum and minimum value it can hold. UMAX...
1926 and UMIN... return the result for unsigned types.
1927 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
1928 struct types. They call above macros.
1929 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
1930 avoid a name conlict with the above.
1931 c-exp.y Added range checking on numeric constants in
1932 parse_number() for completeness.
1933 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
1934 return 0 if working_lang is not language_c.
1936 Thu Aug 8 14:17:22 EDT 1991
1940 breakpoint.c Documentation strings of some commands changed to
1941 eliminate the references to the C language where
1944 Tue Aug 13 15:48:03 EDT 1991
1946 m2-exp.y Added qualified identifiers to the grammar. The semantics
1947 are slightly different from those of the GDB operator ::
1949 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
1950 type_exp, where type_exp is any valid type expression.
1952 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
1953 printcmd.c Modified ptype_command() so it actually parses the input
1954 (necessary for type expressions with scope qualifiers).
1955 Added the function ptype_eval() which expects an
1956 expression composed of one OP_TYPE element.
1957 *.[ch] Replaced all occurences of parse_c_expression with
1959 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
1961 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
1963 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
1965 Small fixes from Peter Schauer:
1967 * infrun.c (child_attach): Lint.
1968 * solib.c (find_solib): Handle shared libs version 2.
1970 Small fixes from David Wood:
1972 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.

1977 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
1979 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
1980 chars_per_line is at maximum (user typed `set width 0'). Fix
1981 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
1983 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
1985 * coredep.c: include ptrace.h where necessary.
1986 * mipsread.c(parse_lines): fix unsigned char problem that was
1987 messing up line numbers on SGI's and possibly other MIPS based
1989 * infrun.c (child_create_inferior): use better test to check
1990 return val from setpgrp().
1991 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
1992 for sgi/irix support.
1994 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
1996 * mipsread.c (parse_symbol): Put non-static procedures
1997 in the global block.
1999 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
2001 Patch together `text_start' and `text_end' for 29K port.
2003 * exec.c (exec_command): If NEED_TEXT_START_END, define the
2004 variables and set them based on the exec file.
2005 * am29k-tdep.c: declare text_start.
2006 * valops.c (call_function_by_hand): declare text_end.
2008 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
2009 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
2010 because machines that do this will also have to know to
2011 set NEED_TEXT_START_END. Besides, it was a redundant way to
2013 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
2014 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
2015 NEED_TEXT_START_END.
2017 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
2019 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
2021 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
2022 Pass MUNCH_DEFINE to munch whenever we run it.
2023 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
2024 format string; use 0x%x instead.
2025 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
2026 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
2027 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
2028 * inflow.c: Handle `short' process group IDs.
2029 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
2030 and check for ptrace errors.
2031 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
2032 (coff_symfile_init): Initialize text_bfd_scnum.
2033 (read_coff_symtab): Use it to find the text [and absolute?] sections.
2034 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
2035 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
2036 Merge target arm case with other "easy" cases. Add target
2037 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
2038 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
2040 * minimon.h, remote-adapt.c, remote-mm.c: Add.
2041 * munch: Cope with RT/PC putting fns in data segment.
2042 Restore ability to override `nm' by specifying MUNCH_NM.
2043 * xconfig/rtbsd, xconfig/ultra3: New host systems.
2044 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
2045 and remote-adapt. Remove encapsulated coff #define's (the
2046 support should go in BFD, and gdb shouldn't know or care).
2047 * tconfig/a29k-kern: Same, but for remote kernel debugging.
2048 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
2049 * tm-29k.h: Update BADMAG (though it should go away).
2050 Allow the register definitions to be overridden in another
2051 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
2052 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
2053 DUMMY_SAVE_GR96, for handling kernel calling conventions
2054 that use GR64+ rather than GR96+.
2055 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
2056 remote debugging of Ultra3 kernel. Includes tm-29k.h and
2057 overrides various things.
2059 * remote-mm.c (mm_attach, mm_wait): Handle attach like
2060 child_attach does, making a clean stop in the newly attached
2062 * remote-eb.c: Lint.
2064 * coffread.c: Make coffread independent of any particular
2065 variant of COFF. Avoid #include-ing any particular one except
2066 internalcoff.h. BFD now passes key values for symbol reading
2067 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
2068 and the symbol masks and shifts); use them.
2069 Remove obsolete end_of_text_addr.
2071 * exec.c: Remove unused include files.
2073 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
2075 * Makefile.in (documentation targets): Pass $(M4).
2076 Bugfix from eggert@twinsun.com (Paul Eggert).

2082 * Makefile.in (VERSION): Update to 4.0.3.
2084 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
2086 * core.c (core_file_command): Print frame at coredump with
2087 its level number, by calling print_stack_frame.
2088 * frame.h: Add selected_frame_level, print_stack_frame.
2089 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
2090 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
2091 Change print_sel_frame and print_selected_frame callers to
2094 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
2095 * symfile.c (free_named_symtabs): Ditto.
2096 * main.c (main): wrap_here needs an arg.
2097 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
2098 (solib_add): Avoid noise.
2099 (solib_create_inferior_hook): Lint.
2100 (sharedlibrary_command): Move dont_repeat to here.
2101 * utils.c (error): Call wrap_here to force buffered output.
2103 Small patches from Peter Schauer:
2105 * coffread.c (start_symtab): Free any existing line_vector before
2107 (read_coff_symtab): Ditto for type_vector.
2109 * source.c (lines_to_list): New variable, replacing function.
2110 (all uses): Use as variable.
2111 (_initialize_source): Add 'set listsize' and 'show listsize'.
2112 * utils.c (lines_to_list): Remove function.
2113 * stack.c (print_frame_info): Use as variable.
2114 * defs.h (lines_to_list): Remove declaration.
2116 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
2118 * breakpoint.c (insert_breakpoints): Restore warning about
2119 the program might be running in another process, but only for
2120 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
2121 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
2123 * utils.c (error): if error_pre_print is set, print the string
2125 * main.c (main, print_gnu_advertisement, print_gdb_version):
2126 Reformat legalese so it always prints, but acts as an "I'm here"
2127 message while symbols are being read. If any errors occur,
2128 print a few newlines to set off the message and start it at the
2129 left margin. Remove mention of "help" command, and don't yak
2130 about symbol reading.
2131 (catch_errors): Error string is now printed first in case of
2133 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
2134 suggest the "help" command.
2136 * Makefile.in (VERSION): Set to 4.0.2.
2138 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
2140 * .gdbinit: Remove useless "rr" command. Set complaints
2141 to 1 for people debugging gdb.
2143 * breakpoint.c, remote-vx.c: Reword strings printed by
2144 catch_errors callers.
2146 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
2148 * WHATS.NEW: "history write -> history save". Doc "write on/off".
2149 (Fix from kenc@viewlogic.com.)
2151 Fix some infrastructure to be able to cope with host and target
2152 machines with different sized basic types (ints, ptrs, etc).
2153 (Idea from pierre@la.tce.com (Pierre Willard).)
2155 * values.c (value_from_longest): Rename from value_from_long.
2156 Handle pointer types as well as integers, so that targets with
2157 different pointer sizes from the host can be accomodated.
2158 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
2159 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
2160 uses of value_from_long to value_from_longest.
2161 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
2162 the correct pointer type to value_from_long{est}.
2164 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
2166 * remote-vx.c: Remove obsolete code for calling functions via
2167 vxworks kludge interface (it referenced value_from_long).
2169 * valops.c (value_string): Find malloc with lookup_misc_func, not
2172 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2174 Make writing to files work properly. (Fixes to BFD are also needed.)
2176 * core.c (core_open): Open file ourselves, read or r/w, depending on
2177 write_files. Use bfd_fdopenr.
2178 * gdbcore.h (write_files): New variable.
2179 * exec.c (write_files): Define variable, add set&show for it.
2180 (exec_file_command): Use write_files to open for read or r/write.
2182 Make shared library reading happen automatically. These changes
2183 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
2185 * inferior.h (stop_soon_quietly): Add to exported variables.
2186 * infrun.c (child_create_inferior): call solib hook, if defined.
2187 (child_attach): call solib hook, if defined.
2188 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
2189 (find_solib): Use lookup_misc_func rather than hand-rolled.
2190 (symbol_add_stub): New stub for catch_errors.
2191 (solib_add): Avoid output if !from_tty. Catch errors rather
2192 than just calling symbol_file_add and bombing.
2193 (solib_create_inferior_hook): Interface with the target process
2194 to let it read and alloc shared libs, then figure out what it did.
2196 * core.c (validate_files): Fix typo, soften warning.
2197 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
2199 * utils.c (fputs_demangled): Avoid duplicate printing if
2200 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
2202 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
2203 (Fix from pierre@la.tce.com (Pierre Willard).)
2205 * main.c (catch_errors): Change argument to a char * from an int,
2206 since a char * can point to a struct full of glop, but an int
2207 is not guaranteed to be able to hold a pointer.
2208 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
2209 breakpoint_re_set_one, breakpoint_re_set): Adapt.
2210 * core.c (core_open, solib_add_stub): Adapt.
2211 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
2213 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2215 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
2216 by adding .NOEXPORT target.
2218 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2222 * Makefile.in (VERSION): Roll to 4.0.
2223 (gdb.tar.Z): Make refcard.ps as well, for shipment.
2225 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2227 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
2230 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
2233 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
2235 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
2236 reflect above name change
2238 * WHATS.NEW: correct pointer to refcard.
2240 * doc/gdb.texinfo: update New Features, Installing
2242 * doc/gdbint.texinfo: add short description of configure +template
2244 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2246 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
2248 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
2250 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
2251 tar file, add dependencies for referenced doc files.
2253 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
2255 * coffread.c, symfile.c, stack.c: saberized.
2257 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2259 * doc/refcard.tex: permuted Essential Commands sec
2261 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
2263 set/show symbol-reloading
2264 default set complaints 0
2266 RET-repeat disabled after prompted long displays
2267 processID (attach) interpretation of 2nd GDB cmdline arg
2269 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
2271 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
2272 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
2273 breakpoint.c, main.c: lint.
2275 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
2277 Install new configuration scheme for GDB and friends.
2279 * config.sub: Translate ordinary names to three-part names.
2280 * configure: Use three-part names internally.
2281 * configure.in: Translate three-part names to filenames.
2283 * README, WHATS.NEW: Update for gdb-4.0.
2284 * Makefile.in: Roll VERSION to 3.99.
2286 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
2288 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
2289 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
2290 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
2291 to single structures rather than arrays; when passing
2292 their address, use &. This avoids trouble with bdead compilers.
2293 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
2294 instead. This avoids portability headaches.
2295 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
2297 * source.c (open_source_file): Avoid ANSI const bdeath by
2298 skipping declaration and then casting result value.
2299 * tm-hp300bsd.h: Clarify comment.
2300 * utils.c (strstr): Result is const char *; ANSI bdeath.
2301 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
2302 since system include file defines it differently from "defs.h",
2303 though the two are equivalent for our purposes.
2304 * tconfig/hp300bsd: Add m68k-tdep.o.
2306 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
2308 * tconfig/sun*4: Remove warnings about system assembler.
2310 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2312 * mcheck.c: Avoid warning about undeclared abort fn.
2313 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
2314 it causes recursive calls to error() when used in cleanups.
2315 To do so requires that we make it a function, so we do.
2316 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
2317 * utils.c (do_cleanups): Remove the current cleanup from the
2318 chain *before* calling it, in case error() is called from it.
2319 The result won't be pretty, but won't be an infinite loop either.
2321 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
2323 * dbxread.c (read_struct_type): Grok anon structs for C++.
2324 (vb_name, vptr_name): Null terminate these strings.
2326 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
2328 Minor bug fixes from BSD Net2 gdb:
2330 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
2331 returns 0, there is no previous frame.
2332 * breakpoint.c (commands_command): If !from_tty, don't call
2333 input_from_terminal_p().
2334 * dbxread.c (record_misc_function): Speed up slightly.
2335 (compare_psymbols): Ditto.
2336 * infcmd.c (do_registers_info): Take a second argument to
2337 determine whether to print float registers. "info registers"
2338 does not do so anymore. "info all-registers" does, now.
2339 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
2341 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
2342 * inflow.c (initialize_inflow): Set tflags_ours correctly.
2346 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
2347 executing_breakpoint_commands if we are interrupted by error.
2348 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
2349 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
2350 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
2351 catch_errors() so we can setup the frame regardless of whether
2352 the shared libs work.
2353 * ieee-float.c (double_to_ieee_extended): Get exponent from
2354 right place in little-endian systems. From John Carey.
2356 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
2358 * main.c: Remove unused terminating_signals and catch_termination().
2359 (long_options): Terminate with a zero element.
2360 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
2361 (gdb_readline): Make call-compatible with readline.
2362 (init_signals): Improve comments re vfork vs. signal.
2364 * utils.c (prompt_for_continue): Use new gdb_readline().
2365 If we prompt for continuation, we don't let CR repeat the previous
2366 command, once we get back to a prompt. It's too easy to keep
2367 hitting CR, expecting "--more--" prompts, and have some long
2368 command start repeating on you.
2370 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2372 * blockframe.c (frameless_look_for_prologue): Speed up by
2373 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
2374 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
2375 Define two variants, one faster.
2376 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
2377 and return zero, rather than giving an error.
2378 (setup_arbitrary_frame): Initialize the PC in the new frame.
2379 (skip_prologue): Add a second arg saying whether we're just
2380 checking for a frameless function or not.
2382 * core.c (core_open, core_close, core_xfer_memory): Move
2383 section table pointers and bfd* into the target_ops.
2384 (core_open): Allow errors in shared lib reading, etc.
2385 (core_files_info): Describe shared library sections.
2387 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
2388 exec_files_info, set_section_command): Move section table
2389 pointers and bfd* into the target_ops.
2390 (add_to_section_table): Add BFD to section table.
2392 * target.c (target_xfer_memory, target_info): Pass target to
2393 xfer_memory and target_info functions.
2396 * gdbcore.h: Move struct section_table.
2397 * target.h: New home of struct section_table.
2399 * solib.c (solib_add): New argument is the target_ops whose
2400 section list is to be added to, if any. Reallocate the
2401 sections in that target to add any that come from shared libs.
2402 (throughout) so_sections renamed to sections.
2403 (solib_xfer_memory): Deleted.
2404 * tm-sunos.h (SOLIB_ADD): Add target argument.
2405 (SOLIB_XFER_MEMORY): Delete.
2407 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
2408 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
2409 from target_ops. It's the same on all targets. Add two section
2410 pointers to target_ops.
2412 * stack.c (find_relative_frame): Dump ancient algorithm for
2413 "down", just use handy "next" pointers.
2414 (frame_command): Don't error if there is no stack; let user
2417 * inflow.c (new_tty_prefork, new_tty): New prefork routine
2418 modifies static state in the parent process; new_tty itself
2419 runs in the child and modifies the child's file descriptors
2420 to match the saved static state.
2421 * infrun.c (child_create_inferior): Call new_tty_prefork,
2424 * infptrace.c (child_xfer_memory): Add ignored target arg.
2425 * remote-eb.c (eb_xfer_inferior_memory): ''
2426 * remote-nindy.c (nindy_xfer_inferior_memory): ''
2427 * remote-vx.c (vx_xfer_memory): ''
2428 * remote.c (remote_xfer_memory): ''. Rename from
2429 remote_xfer_inferior_memory.
2431 * main.c (main): Only try to attach "corefile" argument if
2432 it starts with a digit.
2434 * symfile.c (symbol_reloading): New "set/show" variable.
2435 (symbol_file_add): Shorten message about symbol reading.
2436 (add_symbol_file_command): Merge with add_syms_addr_command,
2437 since this should work on all targets now.
2438 (stop_whining): Default to zero, to shut up complaints
2439 about bad symbol tables on many systems.
2440 (free_named_symtabs): Just exit unless symbol_reloading.
2442 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
2443 and add comment explaining shared library screw.
2445 * source.c: #if defined => #ifdef.
2447 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2449 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
2451 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2453 * doc/rdl-apps.texinfo: provide default readline-appendix finder
2454 (doc/Makefile knows how to make one for local config)
2456 * Makefile.in: use doc/Makefile for doc targets
2458 * doc/Makefile: GDB documentation now has its own Makefile
2459 doc/refcard.tex: renamed from "gdbrc.tex"
2460 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
2461 doc/gdbint.texinfo: add markup in "Cleanups" chapter
2464 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2466 * values.c (baseclass_addr): When reading target memory, use the
2467 length of the basetype, not the upper type. We've only malloc'd
2468 enough space for the basetype, leading to errors in free().
2470 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
2471 ends up as a function specially, since we know the actual type of
2472 the pointed-to address. This (somewhat) fixes display of
2473 expressions that include misc_function_vector names. Try `cond 1
2474 !strcmp("a","b")' then `i b'.
2476 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
2477 The child can be proceeded from inside wait_for_inferior in
2478 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
2479 getting skipped in that case.
2481 * expprint.c (print_subexp): Use filtered output, since the
2482 subroutines we call use it, otherwise the output is horribly
2483 mangled, since output of wrappable stuff comes out late.
2485 * Makefile.in: Bump VERSION to 3.98.1
2487 * infrun.c (child_create_process): Use execlp to find the
2488 shell to exec our target program. This requires some fiddling
2489 with `environ' since there is no execlpe().
2491 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2493 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
2494 Minor rearrangement of refcard permits two new make targets--
2495 gdbrc.dvi DVI output for refcard, using CM fonts
2496 gdbrc.ps PostScript refcard, using PS fonts
2498 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2502 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
2503 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
2505 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2507 * doc/gdb.texinfo: last changes for release.
2508 Minor typo and formatting fixes; incorporated most fixes remaining from
2509 filed mail commenting on earlier drafts.
2511 Added warnings: pipes don't work in run command;
2512 conditions are converse of assertions;
2513 step over fn without debug info goes to next fn;
2514 vars may have "wrong" values near fn entrance, exit
2516 Added example from Kingston on printing repeated nonadjacent values
2518 Added explicit mention that in Emacs gdb mode C-c and C-z are like
2519 shell mode for signals
2521 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
2522 doesn't sound so much like its parent "Stopping and Continuing"; also
2523 moved entries on continue to top of section, so they don't get lost.
2525 Improved installation directions in appendix, added manual formatting
2528 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2530 * configure.in: Remove xm.h and tm.h even if we aren't linking
2531 new ones, so "./configure sun4; ./configure none" does the right
2532 thing. Assume that alldeps.mak and depend are already built in
2533 srcdir, and avoid running "make" (particularly "make depend",
2534 which involves "gcc") from inside configure. Build Makefile
2535 directly rather than building Makefile.conf first.
2536 * configure: Regenerate with above changes.
2537 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
2538 to 3.98. Revise gdb.tar.Z procedure to produce a file
2539 called gdb-$(VERSION).tar.Z but which unpacks into a
2540 directory called "gdb". Move non-source files out of
2541 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
2542 (depend): Don't try to do "gcc expread.y".
2543 (expread.o): Update dependencies by hand.
2545 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2548 Fixed a variety of small typos that prevented info from formatting
2549 cleanly; altered too-long heading for GPL Appendix, as discussed
2550 w/RMS; Changed date on cover to July 91.
2552 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2555 (1) Applied some fixes due to comments from Larry Breed (easier ones
2556 through chapsec 5.2)
2557 (2) Eliminated use of @footnote---had my doubts about it anyways, and
2558 it's broken in latest texinfo
2559 (3) Introduced *some* use of [] for optional arguments, where
2560 explanation is not simpler by listing cmd w arg and cmd w/out arg
2561 separately. Still not using @deffn.
2562 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
2563 couple of headings are too long. Need patches to texinfo or revision
2566 * Partial update to README (which still needs work for this
2567 release!): (1) use of configure corrected for new script,
2568 (2) "make gdb.dvi" and "make gdb.info" mentioned.
2570 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
2572 * symtab.c (lookup_symbol): Don't complain right off about
2573 no debug symbols; use the misc function vector first.
2574 (list_symbols): Use misc function vector to find symbols
2575 that don't have debug info, and print them.
2576 (find_pc_symtab): Temporarily avoid fatal() when psymtab
2577 PC range doesn't match symtab PC range, as it does on the
2578 MIPS because our symtab reading isn't perfect.
2580 * dbxread.c (dbx_symfile_read): Make warning about
2581 "no debug symbols" slightly nicer.
2583 * source.c (select_source_symtab): If "main" symbol exists,
2584 but decode_line_spec can't find line info, don't just return
2585 a zero; try other source symtabs or give an error.
2587 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
2588 their low addresses first, then rip through fixing high addrs.
2590 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
2591 <runene@ifi.uio.no>.
2592 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
2594 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2596 * Minor, mostly mechanical, cleanup of doc subdir for clean
2597 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
2598 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
2600 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
2602 Mostly MIPS and general symbol-reading fixups.
2604 * doc/gdbint.texinfo: Add documentation on symbol-reading
2607 * mipsread.c: Remove kludges around #include "ecoff.h".
2608 Remove redefinitions of a_magic, etc, no longer used.
2609 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
2610 Fix global overview comments to match symfile.c protocol.
2611 (mipscoff_new_init): Eliminate cur_hdr if we have one.
2612 (mipscoff_symfile_read): Eliminate unused code. Avoid
2613 sorting all the symtabs, when all we have read here is psymtabs.
2614 The symtabs are sorted as they are created anyway. Tell
2615 condense_misc_bunches whether we're mainline.
2616 (psymtab_to_symtab_1): Pass filename when recursing, to make
2617 stack trace more informative.
2618 (parse_partial_symbols): Assume cur_hdr as argument.
2619 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
2620 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
2621 the TYPE_NAME of char *, since that's done in symfile.c.
2622 (free_numargs, parse_symbol, add_symbol, add_block,
2623 shrink_linetable): Declare these fns void.
2624 (upgrade_type): Convert tree of if's to switch. Clean up
2625 bogus "off == 0" handling with a complaint. Avoid setting
2626 field bitpos and bitsize of array with lower and upper bounds.
2627 Check specified bitsize of elements against their actual type's
2628 bitsize, and complain if different. Complain about unknown
2630 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
2631 (psymtab_to_symtab_1): Print names of subsidiary files that
2632 are being read in. FIXME, we read far too many files. This code
2633 is not the problem, the problem is in parse_fdr where the psymtabs
2635 (cross_ref): Result should indicate that we used one aux entry
2636 normally, or two if we encountered a "next" entry. This used
2637 to leave the caller pointing at the wrong aux entry.
2638 (add_symbol): If overflowed cur_block, reallocate it larger,
2639 chase all pointers to it, and complain(), rather than clobber memory.
2640 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
2641 (new_field): Only allocate one field initially, not two.
2642 Pull ++ out of macro argument. Simplify.
2643 (_initialize_mipsread): Avoid initialization of importd
2644 global_psymbols and static_psymbols.
2646 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
2647 to properly set pst->symtab; avoid searching for it.
2648 (symfile_fns): Improve comments, add a FIXME.
2649 * dbxread.c: Update comments to reflect symfile protocol.
2650 (read_ofile_symtab, end_symtab): Return the symtab.
2651 (psymtab_to_symtab_1): Set pst->symtab.
2653 * coffread.c (coff_symfile_read): tell condense_misc_bunches
2654 whether we're mainline.
2656 * symfile.h (sym_fns): Remove unused sym_discard member.
2657 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
2659 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
2660 the environment variable is not.
2661 * infcmd.c (finish_command): Use filtered printfs.
2662 * cplus-dem.c: Add struct tags to a few unnamed structs.
2663 * valops.c (value_coerce_array): Improve comments.
2664 * valprint.c (type_print_varspec_suffix): Print array size only
2665 if greater than zero.
2666 * m88k-tdep.c: Shift some lines left by one space, that had
2667 apparently been trashed at some point.
2668 * TODO: More things to do, a few got done.
2670 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2672 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
2673 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
2675 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
2676 * expread.y, findvar.c, symmisc.c: Ditto.
2677 * printcmd.c (address_info): Update printed forms of LOC_
2678 symbols. Elim LOC_EXTERNAL.
2679 (print_frame_args): Keep track of param stack offsets before
2680 re-looking up to find the local register param is kept in.
2682 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
2683 Further integration of mipsread into gdb. Eliminate unused
2684 routines, duplicate declarations. Handle static symbols in
2685 psymtabs as well as external symbols. When reading symtabs,
2686 insert symbols into the correct block (global, static, or a local
2688 (read_mips_symtab, parse_partial_symbols): Don't pass useless
2690 (mipscoff_symfile_read): Don't call select_source_symtab.
2691 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
2692 rather than SYMBOL_VALUE.
2693 (parse_external): Comment clobbering of top_stack.
2694 (parse_partial_symbols): Update comments. Allocate and parse
2695 static symbols as well as external symbols. FIXME, enum values
2696 are not handled in this pass, but should be. Inline new_psymbol.
2697 Use SYMBOL_VALUE_ADDRESS.
2698 (psymtab_to_symtab_1): Read symbols into global static block
2699 by default (until enter some function's local block context).
2700 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
2701 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
2703 * source.c (select_source_symtab): Select a source symtab
2704 from either the symtabs or, failing that, the psymtabs.
2705 (list_command): Update error message.
2706 (forward_search_command, reverse_search_command): Use getc, not
2707 fgetc, for speed. FIXME, add comment about buffers that die if
2708 overrun by long line.
2710 * values.c (unpack_field_as_long, modify_field): Avoid shifting
2711 by an entire word, which is not portable, if we have a 32-bit
2712 field. (Code in dbxread.c already turns such bitfields, if
2713 aligned, into ordinary ints, but fixing this will help for other
2714 symbol formats and for future changes.)
2715 * core.c (core_open): Handle ANSI const brain death.
2716 * utils.c (vprintf): Fix varargs typo.
2718 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
2720 * findvar.c (find_var_value): Handle &function better.
2721 * TODO: Document work needed on &fn and &array.
2722 * printcmd.c (print_address_symbolic): New arg is the prefix
2723 to print if a name is printed.
2724 (print_address_demangle): Honor "set print address" now.
2725 Use new arg above to improve spacing of output.
2726 * valprint.c (val_print): When printing function pointers,
2727 print symbolic form too.
2728 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
2730 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2732 * core.c (memory_error): Reword error msg to mislead less.
2734 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
2736 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
2737 parse_partial_symbols): Use newer BFD internals (external_filehdr
2738 and external_aouthdr), byte-swap the fields that we care about
2739 before using them, and make the file header data local to
2740 read_the_mips_symtab rather than global.
2742 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
2744 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
2745 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
2747 * main.c (command_line_input): Flush stdout and stderr
2748 before every call to readline. This reportedly fixes a bug
2749 that comes up in Sys V running emacs-gdb and/or xxgdb,
2750 when stdin/out are pipes or sockets.
2752 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2754 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
2755 Avoid declaring Makefile dependencies, because GNU Make stupidly
2756 tries to update it if we do.
2758 * coffread.c: Revise for minor changes to bfd internal coff
2761 * configure: If -template= is given a relative path, make it
2762 absolute before recurring in subdirectories.
2764 * configure, configure.in, Makefile.in: Install "configure" script
2765 as replacement for config.gdb.
2766 * config.gdb, Makefile.dist, Makefile.sdir: Remove
2767 * README: Update for configure, mostly. FIXME.
2769 * Add dec3100 as equivalent to littlemips. Indicate in all host &
2770 target config files that they are for the host. When the lines
2771 get copied into the Makefile, this makes it more obvious what's
2774 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2776 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
2777 tabs, which end up in the disassembler output inadvertently.
2779 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
2781 Make it compile cleanly in an ANSI GCC2 environment.
2783 * blockframe.c: <stdio.h>
2784 * cplus-dem.c: free takes a void *, ifdef __STDC__
2785 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
2787 * defs.h (alloca): Avoid doing anything if alloca already def'd.
2788 * stddef.h, stdlib.h: Remove these files.
2789 * symtab.c: Avoid declaring qsort, close.
2790 * symfile.c: Avoid declaring close.
2791 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
2792 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
2794 Assorted other changes.
2795 * dbxread.c: include "libaout.h", not "liba.out.h".
2796 * printcmd.c (print_frame_args): Set recurse properly for
2797 indentation of struct and array parameters.
2798 * valops.c (value_cast): Allow cast to void.
2799 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
2800 single_step() in a target-independent fashion.
2801 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
2802 set up to be ready to continue. This makes us target independent.
2803 * infptrace.c (child_resume): Remove call to single_step; now
2804 can single step a SPARC target of any kind.
2806 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2808 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
2809 docn into separate sections---basically chapters, plus two loose
2810 pieces that can be configured to go in different places. This
2811 allows GNU m4 to preprocess the manual without coredumping.
2813 * Makefile.dist: tell TeX where to find texinfo.
2815 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2817 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
2818 the new target "rdl-apps.texinfo" which captures the Makefile
2819 variable that records where to find the Readline libraries.
2821 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
2823 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
2824 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
2825 * defs.h (const, volatile): Only define if not already defined.
2826 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
2828 * README: Update for release 3.95.
2829 * config.gdb: Don't create readline dir in subdir builds.
2830 * main.c: Include with "..." form for non-system include files,
2831 so "gcc -MM" for "make depend" works.
2832 Include readline files with "...h" rather than <readline/...h>.
2833 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
2835 * coffread.c: Undo minor damage done by Rich Pixley. Use
2836 different internal and external representations of COFF
2837 data structures. Use new BFD routines for swapping them in and
2839 * symfile.c (free_named_symtabs): Avoid freeing file names that
2840 are null or empty. Old i960 tools seem to produce files that
2841 claim to have empty names, causing each successive file read
2842 to blow away the previous one.
2843 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
2844 Move deferred_stores to top of file, but don't separate its
2845 #define's from its variable. Add commentary.
2846 * Makefile.dist: Fix Rich damage; undo "configure" changes in
2847 favor of keeping the (working) config.gdb. Move readline
2850 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
2852 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
2854 * infptrace.c (fetch_registers): no result, since now void.
2855 * tconfig/news: target depends on m68k-tdep too.
2857 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2859 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
2862 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
2863 applied various small fixes due to or inspired by RMS comments
2865 * doc/gdb.texinfo: finished using all RMS comments, save those for
2866 appendices on readline and cmd history (which are in other source
2869 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2871 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
2872 chapter 9; (2) documented 'break' command's menu mode for
2873 overloaded names, in response to hgs problem report C++ p-31
2875 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2877 * doc/gdb.texinfo: (1) better introductory example; (2) more
2878 consistent use of @code, @samp, @file, @kbd throughout; small
2879 cleanups to first three nodes; (3) new "Contributors" node;
2880 (4) Appendix, Renamed Commands; (5) divert specialized startup
2881 instructions to "Targets" chapter for generic manuals, while
2882 leaving them up front for manuals specific to specialized
2883 environments; (6) apply fixes from RMS comments through chapter 4.
2885 * pretex.m4: modify explanatory text slightly (and redefine
2886 "regexp") to keep GNU m4 from complaining. (It still crashes
2887 later, but one step at a time...)
2889 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
2891 * readline/readline.c (update_line): Avoid dereferencing a pointer
2892 before comparing it to its bounds. Saber caught this.
2893 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
2894 and only set PC if tgetstr returned non-null. Saber caught this.
2896 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2898 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
2899 stuff for config manual) here where it counts; updated
2900 to use new subdir structure (gdb/doc/).
2902 * Makefile: generated from above via
2906 * gdbint.texinfo: added instructions on generating gdb.info* files
2907 locally for release. These are ordinary info
2908 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
2909 Makefile)---but due to use of texinfo 2, can't count on makeinfo
2910 to generate these, so we distribute them already formatted.
2912 * gdb.texinfo: included full Info node and menu crud (as generated
2913 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
2915 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
2916 put in comments-for-future gdb.info target (one day makeinfo will

3392 * tm-68k.h (NUM_REGS): Conditionalize on TARGET_SUN3 not sun.
3393 tm-sun3.h: Define TARGET_SUN3.
3395 * utils.c: Use CPLUS_MARKER not '$'.
3397 * cplus-dem.c: Use CPLUS_MARKER not '$'. If CPLUS_MARKER isn't
3398 defined, define it to '$'.
3400 * arm-opcode.h: New file (same contents as before; it had
3401 just been left out of the distribution for a long time).
3403 * tm-68k.h: Put declaration of ext_format_68881 outside the macros.
3405 * main.c: New HAVE_SIGSETMASK #ifdefs.
3407 * coffread.c (read_coff_symtab): Check for "LF%" with all the
3410 * coffread.c (SDB_TYPE): New macro.
3411 various: Use it instead of checking against T_NULL.

3422 * i386-pinsn.c (OP_E): Change %d to 0x%x for consistency.
3424 * putenv.c: New file
3425 Makefile.dist: Add it to $(OBS).
3427 * mipsread.c [!CMUCS]: #include <syms.h>.
3429 * mips-xdep.c (fetch_core_registers): #if 0 out the whole function.
3431 * Move read_memory_nobpt from mem-break.c to breakpoint.c.

3435 * utils.c (_initialize_utils): Rename "set demangle" to
3436 "set print demangle", "set asm-demangle" to "set print
3437 asm-demangle" and "set sevenbit-strings" to "set print

3469 Sun Apr 14 23:08:34 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
3471 * inftarg.c (child_open), remote-vx{,.68}.c (vx_proc_open):
3472 New function to give correct error message.
3474 Thu Apr 11 17:19:41 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
3476 * target.h: Add to_doc and target_preopen.
3477 target.c: Add target_preopen and target_command.
3479 (add_target): Call add_cmd and mess with targetlist->doc.
3480 core.c, exec.c, remote-eb.c, remote-nindy.c, remote-vx.c,
3481 remote-vx.68.c, inftarg.c, remote.c: Add doc field to target struct.
3482 Call target_preopen from open routine.
3484 * main.c: Rename editing_info to show_commands.
3485 (_initialize_main): Rename "info editing" to "show commands".
3487 * source.c: Rename directories_info to show_directories.

3501 Thu Apr 18 18:08:30 1991 John Gilmore (gnu at cygint.cygnus.com)
3503 * symfile.h (free_named_symtabs): Rename from free_named_symtab.
3504 * symfile.c (clear_symtab_users_once, cashier_psymtab,
3505 free_named_symtabs): Move these routines from symmisc.c.
3506 * symmisc.c (same): same.
3507 (free_symtab): Make non-static.
3508 * symtab.h (free_symtab): Declare as exported void fn now.
3509 * dbxread.c (end_symtab, end_psymtab): Change comments.
3510 (initialize_dbxread): Call dbx_new_init() in case the first
3511 command is add-symbols.
3512 * target.c (dummy_target): Permit add_syms_addr_command.
3514 Sat Apr 13 14:46:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3516 Permit symbols to be superseded when new symbol files have
3517 been read in, particularly for VxWorks.
3519 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
3520 to the main file, as well as to include files. Also, put global
3521 functions into the global psymtab, to make "i fun" work.
3522 (end_psymtab): Free named symtabs and psymtabs for a file, once a
3523 new psymtab for it has been read.
3524 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
3525 a file, once a new symtab has been read for it.
3526 * mipsread.c: FIXME. We need to do the same for MIPS, but it
3527 looks harder to determine the top-level block before it's been
3528 queued to the psymtab list.
3530 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
3531 If we have wiped out any old symbol tables, clean up at end of
3533 (symbol_file_command): Don't reference symfile_fns if it's zero.
3535 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
3536 defines for the blocks of a blockvector that contain global and
3537 file-static symbols and the first of the smaller scope contours.
3538 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
3539 decode_line_1, make_symbol_completion_list): Use the above.
3540 * coffread.c (end_symtab, patch_opaque_types): Ditto.
3541 * dbxread.c (end_symtab): Ditto.
3542 * expread.y (block): Ditto.
3543 * mipsread.c (throughout): Ditto.
3544 * symmisc.c (free_named_symtabs): Ditto.
3546 * symtab.c (list_symbols): Process the first symbol of the
3547 static psymbols list.
3548 (types_info): Restore this function from its untimely #if 0.
3549 It's not perfect, but it is better than nothing.
3550 (_initialize_symtab): Restore "info types".
3552 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
3554 * m68k-stub.c: Remote stub for 680x0's, created from
3555 rem-m68k.shar (which is removed).
3556 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
3557 Remove RCS log stuff now that we use CVS and it blows our diffs.
3559 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
3561 * symmisc.c (free_named_symtab): Make it work, in its current
3562 kludgy fashion. Change result to indicate if we blew away bkpts.
3563 * dbxread.c (end_symtab): Accumulate result from
3564 free_named_symtab and print warning if we blew user's state.
3565 * symfile.h: free_named_symtab now returns an int.
3567 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
3569 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
3570 is the first symbol read, even if not mainline.
3571 (dbx_psymtab_to_symtab): symfile might be zero, cope.
3572 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
3573 (set_section_command): New command ("section xxx yyy" -- should
3574 be renamed to "set section xxx yyy" FIXME) which sets the
3575 base address of a section of the exec file, overriding the
3576 virtual address that BFD reports.
3578 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
3580 * exec.c: Add add_syms_addr_command to exec_ops, so you can
3581 load symbols at any address while examining an exec file.
3583 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3585 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
3586 for printing the float info is host-dependent, not
3587 target-dependent. FIXME.
3588 * i386-pinsn.c: Move #includes to top, remove useless ones.
3589 * i386-tdep.c: Don't bother including <.../reg.h> since we
3590 don't use it (and it doesn't exist on host systems).
3592 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
3593 Convert negative numbers properly.
3594 (ieee_test): Make numbers really random; fix format arg.
3596 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
3597 * core.c (core_detach): Unpush core_ops, which might not be on
3598 top. We used to just pop the top, which broke things. Don't
3599 need dont_repeat() any more.
3600 (core_file_command): Psst! Don't repeat it.
3601 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
3602 * expprint.c (print_subexp): Avoid switch fallthru on
3603 BINOP_ASSIGN_MODIFY, so we can print += and such.
3604 * frame.h: Fix typo.
3605 * inflow.c (kill_command): After killing inferior, print our
3606 current frame in the core file, if we have one.
3607 (generic_mourn_inferior): When inferior dies, either select
3608 the current frame (in the new target, e.g. core file), or
3609 set both the current and selected frames to NULL.
3611 Changes from Peter Schauer.
3613 * infptrace.c: Avoid <sys/ptrace.h> on USG.
3615 * Make all file names fit in 14 characters (sigh and damn!):
3616 mv hp300hpux-xdep.c hp300ux-xdep.c
3617 mv symmetry-xdep.c symm-xdep.c
3618 mv symmetry-tdep.c symm-tdep.c
3619 mv convex-opcode.h convx-opcode.h
3620 mv tm-vxworks960.h tm-vx960.h
3621 mv tm-vxworks68.h tm-vx68.h
3622 mv Makefile.srcdir Makefile.sdir
3623 mv gdb-int.texinfo gdbint.texinfo
3624 mv remote-sa.m68k.shar rem-m68k.shar
3625 mv remote-multi.shar rem-multi.shar
3626 * Makefile.dist, README, config.gdb, convex-pinsn.c,
3627 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
3628 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
3631 * command.c (user_info_1, user_info): New command for listing
3632 the user-defined commands.
3634 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
3636 * dbxread.c (really_free_pendings): Clear file_symbols
3637 and global_symbols after freeing them; otherwise, running
3638 this function twice (if it appears twice on the cleanup
3639 chain), we try to free things twice.
3641 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
3642 based on text_addr (the address of text in core), not on addr (the
3643 offset between text in the .o file and in core). This change
3644 is from Peter Schauer.
3646 * main.c: Define ALL_CLEANUPS as a cast of zero.
3647 (return_to_top_level): Use it.
3648 (main): Do all cleanups after each command run as part
3649 of the gdb startup sequence. Also do all cleanups before
3650 entering the command loop, and every time we exit the command
3651 loop and reenter. Before, the cleanups from the startup sequence
3652 were being left undone until the first error!
3653 (command_loop): Rename do_nothing cleanup to command_loop_marker
3654 so we can see it easily when examining the cleanup chain.
3655 (init_signals): Add another do_nothing for signal handling.
3656 (quit_command): Only try to kill target if it has execution.
3657 Problems in the target stack got us into a state where
3658 inferior_pid was nonzero but none of the targets had execution.
3659 In this state you couldn't exit gdb.
3661 * dbxread.c: Two changes from Peter Schauer.
3662 (echo_command): Fflush output after an echo command.
3663 (show_history): Pass all args to cmd_show_list.
3665 * utils.c (init_malloc): Call mtrace to turn on tracing
3666 if the environment variable MALLOC_TRACE is set to a file name.
3667 * mtrace.c: Add source file which provides a log of every malloc,
3668 free, and realloc to a trace file.
3669 * mtrace.awk: Add source file which analyzes the trace file.
3670 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
3671 (VERSION): Roll to 3.94.3.
3673 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
3674 (check_duplicates): Don't bother with watchpoints.
3675 (set_raw_breakpoint): Comment about danger of this routine.
3676 (watch_command): Parse and eval all args before calling
3679 * solib.c (find_solib): Avoid error in referencing memory to
3680 see if any more shared libraries have been added. This is
3681 particularly useful if the target has terminated. Bug reported
3684 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
3685 in bringing up 3.94.2 on the Sun-3.
3687 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
3688 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
3689 expression (in scope) before reenabling watchpoint.
3690 * signame.c (init_sigs): Add missing declaration of i, fix
3691 sys_siglist declaration.
3692 * source.c (list_command): Fixed range computation to use
3694 * stack.c (backtrace_command): Do not allow command if target has
3695 no stack, print informative error message.
3696 * target.c (target_command): Do not write into command line
3697 because this fails if the target command is used in a user defined
3698 command. [This change was enhanced by gnu to support any-
3699 unique-prefix matching on target names.]
3700 * valops.c (value_struct_elt): Avoid infinite loop on an
3701 erroneous attempt to print the member of function (try p main.p).
3703 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3705 * expread.y (name_no_typename): Avoid reduce/reduce errors
3706 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
3707 Since the GDB parser really doesn't use name_no_typename in a
3708 name-only context, the parser can't tell the diff between
3709 names and numbers here. Avoid allowing a name_no_typename
3710 to be a NAME_OR_*INT to resolve the conflict.
3712 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3714 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
3716 * valprint.c (val_print_fields): bitfield printing didn't handle
3717 byte order. Indirect through a few more fns to cope.
3719 * values.c (modify_field): also cope with byte order.
3721 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
3723 Cleanup for release 3.94.2:
3725 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
3726 include files. Roll version to 3.94.2.
3728 * coffread.c (init_stringtab): Read length into unsigned char
3729 array before swapping; don't assume 32-bit longs.
3731 * target.c (target_info): Don't bother with get_sym_file, just use
3732 the symfile global variable.
3733 * symtab.h, symfile.c (get_sym_file): Delete it.
3735 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
3736 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
3737 (read_type): Replace one more error() with complain().
3739 * mipsread.c (parse_partial_symbols): Replace printf with complain.
3741 * i960-tdep.c: Fix copyright attribution.
3743 * config.gdb: Quote all backquotes in doublequotes. You can
3744 quote me on that. BSD 4.4 shell found this one.
3746 * infptrace.c (throughout): The third argument to ptrace is an
3749 * infrun.c (wait_for_inferior): When program has terminated, we
3750 have to call target_terminal_ours before we pop that target off
3751 the stack (e.g. before a call to target_kill or
3752 target_mourn_inferior). This fixes problem where a program
3753 terminates, then GDB stops for (tty output) and you have to type
3754 "fg" to the shell to resume it. FIXME: This code for what to
3755 do after termination really should be in normal_stop instead.
3757 * gdbcore.h (read_memory_check): Change declaration; it changed
3760 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
3761 4.4 prereleases, this avoids a bug in their sgtty compatability
3763 * remote.c: Use terminal.h rather than hand-rolling the same.
3765 * signame.c, signame.h (psignal): Arg is unsigned, not int.
3766 * utils.c (strsave, strstr): Fix arg types.
3767 * valprint.c (val_print): lint
3769 MIPS symbol table support from Per Bothner:
3771 * symfile.c (symtab_fns): Remove initializer table that needs to
3772 be hacked for each new symbol file format supported.
3773 (add_symtab_fns): New function, chains symbol table
3774 handlers into the global list.
3775 (symfile_init): Search this list.
3776 * symfile.h: Add next pointer, declare add_symtab_fns.
3777 * coffread.c (_initialize_coffread): Call add_symtab_fns.
3778 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
3780 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
3781 symbol *). Thus, we no longer need the hack to trash
3782 pst->filename. Good, since that hack confused code in symfile.c!
3784 (reorder_symtabs, destroy_all_symtabs): Removed static
3785 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
3786 Instead, the latter now uses a temporary array (stack-allocated
3787 from an obstack, and then freed).
3789 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
3790 haven't been set in the outermost stBlock of a procedure. This was
3791 a problem with f77 binaries on Ultrix 4.?.
3793 (new_symtab, new_symbol, new_type): Continue changing code to use
3794 obstacks more and otherwise conform to dbxread internal style.
3795 Made the free_code of symtabs be free_linetable (as in dbxread)
3796 instead of free_contents. This implies memory leaks when reading
3797 a new symbol table, until the conversion is finished. Did change
3798 (struct symbol) and (struct type) to be allocated on the
3799 symbol_obstack. Blocks and blockvectors are among the things
3802 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
3803 tested much, but it solved one problem (reported by Meissner), and
3804 cleans up some other things. The problem happened when an
3805 included file contains actual code (functions) and not just
3806 definitions. The mips coff is a little inconvenient there, since
3807 it may cause a procedure to be mapped to the wrong psymtab.
3809 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
3810 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
3811 this will need work for the new core paradigm.
3813 Opcode patches from the net:
3815 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
3816 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
3817 missing altogether - they are added here. From Bruce Bauman.
3818 * mips-opcode.h: The low mask for C0 instructions was too small.
3819 From Garrett Lau. I modified the fix to check the entire 32-bit
3822 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
3825 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3827 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
3829 * dbxread.c (read_type): Pointer subtraction (value_sub in
3830 valarith.c) sometimes failed because the types of the
3831 pointers being subtracted were not identical.
3832 These differed because dbxread.c was allocating pointer types
3833 using dbx_alloc_type+smash_to_pointer_type instead of
3834 lookup_pointer_type. I failed to find a justification for the
3835 former, so I changed it to use the latter. Similarly, I
3836 replaced smash_to_function_type by lookup_function_type,
3837 and smash_to_reference_type by lookup_reference_type.
3839 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
3840 _initialize_mipsread): corresponding changes.
3842 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
3844 * source.c (mod_path): Do tilde_expand on each component of the path,
3845 rather than on the (list of) paths as a whole.
3846 (print_source_lines): Set first_line_listed in addition to
3847 current_source_symtab and current_source_line. If the source was
3848 not findable, after a "dir" command to fix the problem,
3849 a "list" would get the wrong lines.
3851 While I was there... (gnu):
3853 * dbxread.c (read_type): Change error to complaint.
3855 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3857 First attempt at detailed understanding of symbol table memory alloc.
3859 * dbxread.c (dbx_symfile_read): Free our string table if we
3860 aren't the mainline. Free the "info" struct since we're done with
3862 (init_psymbol_list): Free any previously allocated psymbol lists.
3863 (): FIXME: Should realloc-down the psymbol lists when done reading
3864 the main symbol file?
3866 * symmisc.c (free_symtab): Free fullname field too.
3868 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
3869 (REGISTER_ADDR): Make result type unsigned int.
3871 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
3872 define REGEX must also define REGEX1 (its dependency).

3909 in raw hex as well as float format, regardless of whether it is
3910 a "virtual" convertible register.

3912 regs as a double, just in case it's being used that way.
3913 * values.c (unpack_long): Comment on array/function coercion.
3914 (unpack_double): Argument is in target byte order now. For
3915 integer arguments, just call unpack_long and float the result.

3917 * remote-nindy.c: Use ieee-float stuff.
3918 (nindy_fetch_registers): Unpack double regs to host double, then

3932 Changes from a bringup on the DEC Vax under Ultrix 4.0.
3934 * coredep.c (fetch_core_registers): Pass end-address of register
3935 section to register_addr as expected. Don't call supply_register
3936 if we'd just pass it garbage.

3985 * inftarg.c (child_detach): Pop the child_ops vector if the
3986 detach is successful.
3987 * remote-nindy.c (nindy_create_inferior): Don't push a new
3988 nindy_ops since nindy uses the same one for execution and memory
3990 * core.c (core_ops): Use child_attach and child_create_inferior
3991 rather than default attach and create_inferior functions.
3993 Handle floating point registers in core files.
3995 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
3996 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
3997 This version untested since BFD doesn't yet support sun3 core
3999 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
4000 conventions. Fix comments and style. This version has not
4001 been compiled yet, since we have no HP inhouse.
4002 * core.c (get_core_registers): Look for two sections, ".reg"
4003 and ".reg2", and pass both to fetch_core_registers sequentially.
4005 Revise directory path yet again.
4007 * source.c (forget_cached_source_info): Not static any more.
4008 (init_source_path): New default source path is "$cdir:$cwd".
4009 (dir_command): Handle variable arguments ($cdir, $cwd).
4010 (source_info): Print "Compilation directory" rather than
4011 "Originally compiled in" to remind people of $cdir.
4012 (openp): If the path contains $cwd, use current directory.
4013 (open_source_file): If compilation directory is known, replace
4014 first $cdir in path with the compilation directory.
4015 (print_source_lines): Even if we can't print the lines, set the
4016 current symtab and line for future commands like "info source" or
4017 "breakpoint". Also, error message now contains the file name,
4018 line number, and file access error message.
4019 (_initialize_source): Fix help text to describe changes.
4020 * main.c (cd_command): Forget cached source info when we chdir.

4025 * coffread.c (read_one_sym, init_linetable, init_stringtab):
4026 Byte-swap COFF symbol tables if necessary when reading them in.
4027 Use complain() to replace error message in one spot. Needs
4028 corresponding change in bfd/coff-code.h to make some symbol
4029 swapping routines non-static.

4043 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
4045 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
4046 <rpc/rpc.h> and <rpc/types.h>.
4048 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
4050 * i960-tdep.c (examine_prologue): Add new argument limit,
4051 which stops the scan at the end of the prologue, or at the PC.
4052 This fixes a problem where it walks down into the code for the
4053 user's statements if that code looks like function prologues.
4054 Mark Fox and I have been bouncing this code back and forth, making
4055 small changes to it. Callers changed to match.
4057 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
4059 Cleanup for gdb-3.94 release final:
4061 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
4062 the .c files from vx-share and nindy-share, from the various
4063 macros, since they are not found via ALLDEPFILES.
4064 (SFILES): Add tm-i960.h.
4065 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
4066 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files

4073 * am29k-tdep.c: Add contribution line.
4074 (examine_prologue): Cache information about function prologues in
4075 the misc-function-vector to avoid lots of references over the
4076 serial line while examining instructions.
4078 * core.c (core_close): New function made from cleanup_core.
4080 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
4081 remote-vx.c, remote.c, target.c, target.h,
4082 Update target_ops vector to add attach, close, and load entries.
4083 Use add_syms_addr_command, not add_file_addr_command, for
4084 add_file. Break out close routine from existing code.
4086 * dbxread.c (really_free_pendings): Don't free pending_blocks;
4087 they are in an obstack.
4088 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
4090 (define_symbol): Add symbol type parameter; change callers;
4091 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
4092 it to influence the symbol class on the i960.
4093 (define_symbol): Swap LOC_CONST's into target byte order.
4095 * exec.c (exec_close): New function.
4096 (exec_file_command): Call it.
4098 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
4099 Fix byte order of frame pointer.
4100 (read_var_value): Result of 0 if var's value can't be found,
4101 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
4102 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
4103 (locate_var_value): Use read_var_value and use its lazy address
4104 as the location of the var's value. Lint.
4106 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
4109 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
4110 obsolete Intel versions in favor of vxgdb versions.
4111 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
4112 code dealing with byte order of values, which Intel did in host byte
4113 order rather than gdb-4's target byte order.
4114 (i960_frame_chain_valid): Move to nindy-tdep.c.
4115 (examine_prologue, skip_prologue, frame_find_saved_regs,
4116 frame_args_address, leafproc_return, saved_pc_after_call,
4117 pop_frame): Add vxgdb versions from Mark Fox.
4118 (examine_prologue, frame_struct_result_address): Add code
4119 to deal with the saved value of G13 (struct return address
4121 (frame_args_address): Modify Mark's version to prefer the
4122 saved value over the current value in the topmost frame.
4123 Cache result in the frame info to avoid performance hair in
4125 (print_fault): Add gdb960 code for printing faults.
4126 (_initialize_i960): Actually call check_host.
4128 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
4129 add stub routines. FIXME, these currently just return zero!

4132 (attach_command): Call target_attach, not target_open, now.
4134 * infrun.c (normal_stop): Make global, not static, for vx_attach.
4135 (child_attach): Rename from child_open.
4136 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
4137 don't confuse it with a zero step_resume_break_address.
4139 * inftarg.c (child_detach): Eliminate inferior_pid test.
4140 (child_files_info): Clean up message a bit.
4141 (child_ops): Use child_attach, not child_open, to attach.
4143 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
4144 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
4145 findvar.c to here, since it depends on the contents of the
4146 shadow_contents of breakpoints, but keep if #if 0 since it is
4149 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
4152 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
4153 (ptype_command, display_command): Eliminate have_inferior_p and
4154 have_core_file_p in favor of target_has_stack or
4155 target_has_execution.
4156 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
4157 code for actually finding the values of arguments, though we still
4158 keep track of the maximum stack offset for use in printing unnamed
4159 arguments. Handle missing FRAME_ARGS_ADDRESS.
4161 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
4162 (struct nindy_regs): Define registers passed to/from nindy.
4163 (nindy_fetch_registers, nindy_store-registers): Translate between
4164 nindy and GDB formats for the registers.
4165 (dcache_init): Statically allocate the cache, since it was being
4166 allocated by a malloc that was never freed anyway.
4167 (nindy_create_inferior): Error, not core dump, if no exec file.
4168 (nindy_before_main_loop): Use target_load, not target_add_file.
4170 * remote-vx.c (net_load): Specify large timeout for load
4171 requests. Allow user to break out with INTERRUPT.
4172 (net_break): Remove useless code, clean up. Change callers.
4173 (parse-args, skip_white_space, find_white_space): Clean up arg
4174 parsing to cope with quoted strings.
4175 (net_wait, net_quit): Never call error, just return status.
4176 (vx_read_register, vx_write_register): Cleanup status checking.
4177 #ifdef the code based on which CPU we are using (960 or 68k),
4178 FIXME, this should be completely general but it isn't yet.
4179 (vx_xfer_memory, vx_resume): Cleanup status checking.
4180 (vx_run_files_info): Improve message.
4181 (vx_load_command): Renamed from vx_add_file_command. Allow load
4183 (net_ptrace): Remove unused routine.
4184 (vx_wait): Adopt code from vxgdb960 to cope with broken
4185 connections to target machine and prompt to disconnect. Remove
4186 debug printouts. Map some EVENT_'s to SIGnals.
4187 (add_symbol_stub, vx_open): Print names of object files we found,
4188 and "ok" if we read their symbols OK. Clarify output in general.
4189 (vx_attach, vx_detach, vx_kill): Add these commands.
4190 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
4191 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
4192 "info files" output, and create_inferior, since we already have
4195 * stack.c (frame_info): Replace Frame_unknown with 0.
4196 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
4197 (return_command): Pop until the PC matches as well as the FP,
4198 so it works even if the FP is shared with another function,
4199 as in "frameless" or "leaf" procedures.
4201 * symfile.c (load_command): renamed from add_file_target_command.
4202 (add_syms_addr_command): renamed from add_file_addr_command.
4203 (add_syms_command): Stub to call target_add_syms.
4204 (_initialize_symfile): Change command names and descriptions,
4205 add-file => add-syms, and load from alias to its own command.
4207 * target.c (kill_or_be_killed, maybe_kill_then_attach,
4208 maybe_kill_then_create_inferior): Default for attempts to start
4209 a process, if one is already running, is to ask about killing
4210 it and retry if yes.
4211 (upstack_create_inferior): #if-0 it, strata obsolete it.
4212 (push_target, unpush_target, pop_target): to_close() a target
4213 before unstacking it.
4214 (target_info): Renamed from target_files_info.
4215 (_initialize_targets): Rename "i files" as "i target", accessible
4218 * target.h: Improve comments about the target_ vectored routines.
4220 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.

4223 (SKIP_PROLOGUE): No longer a no-op.
4224 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
4225 (*_REGNUM): Sort register numbers.
4226 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
4227 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
4228 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
4229 are now 10 byte extendeds, not 8 byte doubles.
4230 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
4231 for nindy versus vxworks targets. FIXME, this should possibly go
4232 in the target vector.
4233 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
4234 frame_saved_regs and arg pointer with each frame.
4235 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
4236 (FRAME_ARGS_ADDRESS): Use cached result.
4237 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
4238 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
4239 (PRINT_RAMDON_SIGNAL): Call print_fault.
4240 (POP_FRAME): Now works.
4242 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
4243 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
4244 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
4245 (ADDITIONAL_OPTION_HANDLER): use target_load, not
4248 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
4249 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
4251 * valarith.c (value_subscripted_rvalue): Avoid handling
4252 floats and doubles specially; it gave alignment errors. Lint.
4254 * valops.c (value_of_variable, value_of_this): Error if unknown
4257 * valprint.c (print_floating): Bcopy rather than pointer-deref,
4258 to avoid alignment problems.

4261 (val_print): Use unpack_long rather than pointer-deref.
4264 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
4265 to avoid alignment problems.
4266 (value_being_returned): Error if return value unknown.
4267 (set_return_value): Add bogosity warning, FIXME. *
4269 * TODO: A woman's work is never done.
4271 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
4272 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
4273 Add ieee-float.o to OBS.
4274 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
4275 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
4276 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
4278 Changes to generalize the VxWorks RPC protocol slightly, to handle
4279 i960 as well as 68000.
4281 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
4282 * vx-share/reg.h: Produce i960 regs #ifdef I80960
4283 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
4284 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
4285 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
4286 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
4287 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
4288 so they will move in target byte order rather than network
4289 byte order (happens to be the same).
4291 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
4293 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
4295 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
4298 Add contribution lines to various files, showing where they
4301 * breakpoint.c (break_insn, check_break_insn_size,
4302 read_memory_nobpt): Remove to mem-break.c.
4304 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
4307 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
4308 entry has bad register number. This change is not
4309 tested in this release, FIXME.
4311 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
4314 * value.h: Force value's contents field to be aligned to hold
4315 at least a double or a long long (if supported). This avoids
4316 doing bcopy's in and out of the contents field.
4318 (step_1): Avoid coredump under obscure circumstances when we
4321 * symtab.h (misc_info): Add field to misc function vector for
4322 any kind of cached information the target code desires. AMD
4323 29000 uses this to avoid repeating examine_function_prologue's.
4325 * coffread.c: Lint. Remove static symfile, read_section_header.
4326 core.c (have_core_file_p): Lint: remove.
4327 expprint.c (print_subexp): Lint.
4328 infptrace.c, valops.c, valprint.c: lint.
4330 Roll in changes from vxgdb-5.0.1:
4332 * symtab.h: Comment byte order of each address class. Add
4333 LOC_LOCAL_ARG for frame-relative args (960).
4334 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
4335 symtab.c, symmisc.c: ditto.
4337 * infrun.c (init_wait_for_inferior): Clear stop_signal.
4339 * remote.c (remote_resume): Error if resume with a signal.
4341 * symfile.c (prim_record_misc_function): Clear misc_info.
4342 (fill_in_vptr_fieldno): Check stub type of arg.
4344 * valops.c (value_cast): Avoid looking up names of types whose
4345 name we don't know, to prevent coredump. Sun CC produces typedef
4346 rtx and the name of *rtx is zero...
4348 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4350 Roll in changes from final AMD 29000 port (Tiemann).
4352 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
4353 for ../include/a.out.encap.h. This might not work now that BFD
4354 is separately compiled. Instead, BFD support for encap will have
4355 to translate machine type 29k into the right COFF_MAGIC.
4357 * infcmd.c: Remove references to inferior_pid that aren't used
4358 in actual ptrace calls; use target_has_execution, etc.
4359 (have_inferior_p): Remove function.
4360 (program_info): Print target info rather than "process number";
4361 avoid gratuitous messages unless from_tty.
4362 (run_stack_dummy, finish_command): Set proceed_to_finish.
4363 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
4364 main.c: Lint. Lose have_inferior_p().
4365 inferior.h (have_inferior_p): Remove, lint.
4366 (proceed_to_finish): Add flag to ask that all regs be saved
4367 by normal_stop, for the few commands that need it, speeding up
4368 serial I/O. Add comments to stop_registers.
4370 * remote-eb.c: Remove newline from breakpoint message we grep
4371 for. Never time out when running the user program.
4375 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
4377 Roll in changes from vxgdb-5.0.1:
4379 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
4380 symbol in its raw form, we are processing an unlinked ".o" file.
4381 See if the target environment has assigned it an address, using
4382 target_lookup_symbol (VxWorks does), and enter it into the symtab
4385 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
4386 68k versions for a simpler version that assumes zero FP at bottom.
4387 Fixes bug of truncated stack reports.
4389 * target.h (target_lookup_symbol): Define this routine's args
4390 and result, finally.
4392 * target.c (nosymbol): Default routine for target_lookup_symbol.
4393 (target_default): Default lookup_symbol and call_function too.
4394 (files_info): Only print has_all_memory warning if a non-dummy
4397 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
4398 vx_convert_from_virtual): If target does not have floating point,
4399 zero register "values", and avoid doing cross-net conversions.
4400 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
4401 (vx_open): Rearrange code that attaches to target and reads
4402 symbols for all loaded modules, to work if some of the modules
4403 are not accessible. Add symbol_stub() and add_symbol_stub()
4404 as callbacks from catch_errors(). Allow connect attempt to be
4405 interrupted painlessly with ^C (FIXME, there are still some bugs
4406 if the interrupt happens during symbol reading.). Print
4407 final message with puts_filtered, since symbol messages are
4412 * main.c (catch_errors): Only print errstring if non-null.
4413 (command_loop): Avoid an ioctl per command to test ISATTY.
4415 * remote-vx.c (net_load): make static; avoid sophomoric msg.
4416 (vx_xfer_memory): Return correct result!
4417 (vx_files_info): Indicate whether target has float or not.
4418 (vx_lookup_symbol): Complain, not error, if target gone.
4419 (vx_open): Print "Connected" msg before disabling immediate-quit.
4420 [FIXME: lookup_symbol and vx_open changes need testing.]
4422 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
4423 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
4424 contributor lines and update copyrights to 1991.
4426 Changes from an attempted H-PUX host port:
4428 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
4429 defines PT_ATTACH and PT_DETACH but not PT_KILL.
4430 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
4431 * remote-vx.c: include <sys/time.h> for HPUX.
4432 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
4433 "core_file_command" routine to BFD regime. May not work yet.
4435 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
4437 * xgdb.c: Replace X10 version with some VJ version.
4438 (FIXME: Its copyright assignment is not on record.)
4439 * xgdb.c: Update include files to X11R4 (Xaw crud).
4440 (xgdb_display_source, create_text_widget): fix call to
4441 get_filename_and_charpos. Rewack source window stuff for X11R4
4442 (gleaned from include files, and "nm's" of binary libraries, since
4443 I had no doc available).
4444 (append_selection, append_selection_word): Disable with FIXME
4445 since R4 changed interface here.
4446 (create_buttons): Add back the old set of buttons.
4447 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
4449 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
4450 Roll VERSION to 3.94 (not yet final though).
4452 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4454 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
4455 obstack_int_grow, obstack_int_grow_fast): Eliminate
4456 cast on left of assignment, which gives MIPS cc fits and is
4459 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
4460 F_ALIAS. Use printf, not fprintf, when not passing a file
4462 (compare_opcodes): Check that identical instructions have
4463 identical opcodes, complain otherwise.
4465 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
4466 was reported by Roland McGrath.
4467 (unimp): Only match if exactly zero instruction. (Roland)
4468 (branches and traps): Generate all variations of these
4469 instructions with macros, based on a single call that defines
4470 each condition name and its binary representation.
4471 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
4473 * valprint.c (val_print_fields): Take, and use, format parameter.
4474 This means that "p/x struct" again prints the elements in the
4475 desired format. Changed callers.
4477 * stack.c (frame_info): Use filtered output, and indicate wrap
4478 points. Remove kludgy formatting designed to avoid line wrap.
4480 * utils.c (wrap_here): If the line is already full (because
4481 we had printed a long indent or long wrapped string), do an
4482 immediate newline-and-indent.
4484 * m68k-pinsn.c (print_insn_arg): Bugfix from
4485 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
4486 instruction is incorrectly disassembled as bkpt #8.
4488 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
4489 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
4490 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
4491 and then will dump core (sometimes). I traced it back to an
4492 uninitialized symfile_name in psymtab_to_symtab.
4493 (const_vol_complaint): Add quotes to message.
4494 (define_symbol): Only believe line number if gcc_compiled.
4495 Avoid allocating symbol if we will not return it.
4497 Add target strata support so that newly established targets go
4498 into their right place in the target stack (e.g. a new exec file
4499 doesn't wipe out the ability to access the running process).
4501 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
4502 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
4503 and initialize it properly in all the targets.
4505 * target.h: Document strata. Change return type of push_target.
4507 * target.c (nomemory): new function for dummy memory access.
4508 (tcomplain): Rename complain, now also used in symfile.c.
4509 (push_target): Push targets within strata. New return value shows
4510 whether new target is on top of stack or not. Always keep dummy
4512 (target_files_info): Ignore dummy target.
4514 * core.c (core_open): Warn user, and skip accessing file, if the
4515 core target is not the topmost target in the stack.
4516 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
4519 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
4520 target_ops, it doesn't belong there since we have no regs there.
4521 Change name of target from machine => memory to clarify.
4523 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
4525 * Freeze version 3.93 for release.
4527 * Makefile.dist: Handle vx-share and nindy-share subdirs
4528 properly when building gdb.tar.Z.
4530 * symtab.c: lint; add no_symtab_msg to consolidate the messages
4531 printed in various places, so I could change just one copy.
4533 * dbxread.c, coffread.c: Change references to bfd->iostream
4534 to cast to FILE *, now that BFD avoids needing types defined
4535 in other header files.
4537 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
4539 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
4540 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
4541 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
4542 (actually gcc -Wall).
4544 * dbxread.c: Remove first_global_sym, last_global_sym, since
4545 they are never referenced.
4547 * defs.h (baud_rate): Declare.
4548 main.c: Define it, and add the -b option to set it.
4550 * gdb-int.texinfo: Add text on how to define a new host or target
4551 architecture, prompted by Per Bothner's questions about MIPS
4554 * gdb.texinfo: Document "complaints". Change doc of -q since
4555 gdb no longer prints the copyright and blurb if you specify a file
4556 name to be debugged (just like Emacs). Add doc for Nindy-specific
4557 command line flags for specifying target serial port and such.
4558 Update copyright to 1991.
4560 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
4561 has taken over for us the job of ripping up executable files. The
4562 crud caused Per Bothner's port to not compile.
4564 * infrun.c (normal_stop): Avoid printing "Program exited
4565 normally" if we are in batch mode. This allows a GDB which
4566 executes a program on a target system, to behave like a Unix
4567 command (input from stdin, output to stdout, no extraneous
4570 * main.c (main): Allow additional machine-dependent command line
4571 options to be specified with the ADDITIONAL_OPTIONS,
4572 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
4573 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
4574 processing to occur just before the main loop with
4575 BEFORE_MAIN_LOOP_HOOK.
4576 (main): If a "core file" argument is specified, and it is not a
4577 core file, try it as a process ID to attach.
4578 (symbol_completion_function): Attempt to cope with
4579 "show screen-" TAB, not very successfully. This needs more work,
4581 (batch_file): New function, returns whether we are reading
4582 commands from an interactive tty on stdin, or from somewhere else.
4583 Called by normal_stop since it doesn't get from_tty passed down
4584 to it like many commands do.
4586 * remote-nindy.c: Handle command line options for nindy
4588 (nindy_before_main_loop): Prompt user for tty name if they
4589 don't specify it before getting to the interactive command loop.
4591 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
4592 and -r command line options. Also add hook before main loop
4593 to make it easy to specify a tty.
4595 * TODO: More things to do, one done.
4597 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
4599 * dbxread.c: Make complaint() calls pass pointer, not struct.
4600 Add complaints about badly formatted C++ type information
4601 (const/volatile indicator, and parse errors resulting in
4602 error_type). Fix C++ virtual member fn comment.
4603 (read_struct_type): Avoid bumping pointer if we got a parse
4604 error; this prevents our walking beyond the end of a string.
4605 Terminate loop on null char as well as semicolon.
4606 (process_one_symbol): Fix the LBRAC fix so that it uses the
4607 last previous SLINE, FUN, or SO record's PC address. C++ debug
4608 symbols did not have SLINE records in a useful order compared
4609 to the LBRAC records.
4610 (define_symbol): Handle "catch" records.
4612 * symtab.c (check_stub_type): Added new complain
4613 `stub_noname_complain' and added a consistency check to
4614 keep the debugger from crashing when finishing from an
4615 exception frame. A real fix will be needed later.
4617 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
4619 * infcmd.c (attach_command): Make global.
4621 * Makefile.dist (REMOTE_OBS): Make these compile by default,
4622 but make them easy to comment out. Perhaps later they should
4623 be enabled by what CPU you configure for? FIXME.
4624 (VERSION): Roll to 3.93.
4625 (pinsn.o): Remove rule for obsolete file.
4626 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
4628 Run down a problem that manifested by printing the wrong function
4629 name in stack traces of read_ofile_symtab. Turned out that the
4630 problem was the SunOS 4.1.1 (and previous) C compiler outputs
4631 the LBRAC symbol with an address in the *data* segment, which
4632 blew our binary search through the blocks.
4634 * dbxread.c: Use the complain() facility consistently to bitch
4635 about problems in the symbol file we are reading.
4636 (finish_block): Add code to check the nesting of the blocks;
4637 complain and Procrust them to fit if wrong.
4638 (make_blockvector): Check the order of the blocks, complain
4639 [but don't cope] if wrong.
4640 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
4641 symbols to be sure their PC value is greater than the last SLINE
4642 (line number) symbol we've seen, complaining and adopting the
4643 SLINE PC value if wrong.
4645 * symfile.h (struct complaint, complaint_root, complain,
4646 clear_complaints): Add.
4647 * symfile.c (complain, complaint_root, clear_complaints): Add
4648 facility to deal with non-fatal complaints and to regularize their
4650 (symbol_file_add): Clear complaint counters to allow new complaints.
4651 (initialize_symfile): Add 'set complaints' and 'show complaints'.
4653 * dbxread.c (dbx_symfile_read): Remember the address and size
4654 of the string table for the main symbol file, so we won't read it
4656 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
4657 to avoid reading the string table yet again. Lint.
4658 (throughout): Improve filtered output, including word wrap.
4659 (read_range_type): Improve Bothner's fix to handle other types too.
4661 * utils.c: Improve line wrap implementation. Handle unlimited
4662 width by making chars_per_line unsigned.
4663 (puts_filtered): New, easy, function.
4665 * defs.h (puts_filtered): add.
4667 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
4668 call the identical sort_symtab_syms() in symfile.c instead.
4670 * expread.y: Suggest the `file' command rather than `symbol-file'.
4672 * command.h (enum var_types): Add zinteger for seroable
4674 * command.c (do_setshow_command): Handle var_zinteger. Restructure
4675 nested if's into a switch.
4677 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
4678 we did not stop because of a breakpoint (it must have been for
4679 some other reason, like a "stepi"), so don't print anything.
4681 * symtab.c: Include <sys/types.h> all the time. Now that BFD
4682 doesn't include <sys/types.h>, old SunOS's require it for
4685 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
4687 A test port of gdb-3.92.6 to the Sony NEWS.
4690 Don't normally link in remote- or vx stuff.
4691 Some of it doesn't compile, and it wastes space for 99% of the users.
4692 Remove reference to no-longer-used HAVE_VPRINTF.
4693 Fixed BFD_DEP typo to BFD_DIR.
4695 Fix cast in arg to bfd_h_getlong.
4696 Make char *prefix be const.
4697 Fix how certain range types are mapped into builtin unsigned int types.
4699 Remove 2 #includes. They cause errors (on Sony, at least),
4700 and aren't needed (they wern't in earlier versions).
4702 print_address_symbolic should never demangle labels
4703 (since it prints *assembler-level* labels).
4705 [This was superseded by the change to printcmd below.]
4708 Add some "volatile" return types to avoid warnings.
4709 If MISSING_VPRINTF add vprintf function and not just macro
4710 (since vprintf is used in printcmd.c).
4712 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
4713 (The latter isn't grokked by some PCC-based compilers.)
4715 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
4717 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
4718 * nindy-share/coffstrip.c
4719 Added some forward declarations (otherwise, gcc complains
4720 about implicit extern redefined as static).
4722 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
4724 Changes inspired by Per Bothner:
4725 * printcmd.c (print_address_symbolic): Take additional parameter
4726 specifying whether to demangle.
4727 (print_address): Pass in asm_demangle to control demangling.
4728 (print_address_demangle): New fn, takes explicit arg to control
4730 * utils.c: Add new vars demangle and asm_demangle, and let them
4732 (fputs_demangled): If !demangle, just print the argument.
4733 (fprint_symbol): If !demangle, just print raw symbol.
4734 * valprint.c (val_print): Call print_address_demangle rather than
4735 print_address, to cause demangling to depend on the global
4736 rather than assembler-level demangling setting.
4737 * WHATS.NEW, gdb.texinfo: Document.
4739 * main.c (show_command): Show all settings if no arg.
4740 (initialize_main): Make "info set" the same as naked "show".
4741 * command.c (cmd_show_list): Handle prefix commands in the
4742 list, and print the name of the setting as well as its English
4743 description and value.
4745 Allow gdb functions to specify where a line should wrap if it
4746 exceeds the size of a terminal line. Use it to make the output
4748 * utils.c (set_screen_width_command): New fn, mallocs a buffer
4749 of the right size when screen width changes.
4750 (set_screensize_command, screensize_info): Remove #if 0'd fns.
4751 (wrap_here): New fn, indicates a point in the output where we
4752 should wrap the line rather than just letting it overflow at a
4754 (fputs_filtered): Implement wrapping.
4755 (n_spaces): New fn, returns a pointer to N spaces.
4756 (print_spaces_filtered): Use n_spaces.
4757 * defs.h (n_spaces): Declare.
4758 * stack.c (print_frame_info): Wrap with 4-space indent after
4759 fn name and before filename and line number.
4760 * printcmd.c (print_frame_args): Wrap with 4-space indent
4761 before each argument name is printed.
4762 * valprint.c (value_print): Wrap with no indentation before
4764 (val_print_fields): Wrap with indentation relative to nesting
4765 level before each field name.
4766 (val_print): Wrap with nesting indentation before array elements.
4767 * command.c (do_setshow_command): Avoid extra newlines,
4768 wrap with 4-space indent around values printed, end with period.
4769 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
4771 * breakpoint.c (breakpoint_1): Implement addressprint for
4772 "info breakpoints" display. Change file name and line number
4773 format to " at file:nnn" rather than " (file line nnn)".
4774 * gdb.texinfo: Document.
4777 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4779 Frozen for gdb-3.92.6 release.
4781 README, WHATS.NEW: Update for 3.92.6 release.
4783 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
4784 coffread.o from configs since it is now built by default.
4785 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
4786 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
4787 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
4788 from configs since it is now built by default.
4790 Makefile.dist: Update for release 3.92.6. Handle files that
4791 have been moved to ../include, ../getopt, or ../bfd. Add
4792 saber.suppress and tests directory. Add config.status to
4793 the release (it will say "none").
4795 coredep.c: Minor formatting fixes.
4797 These changes were made in early December but only checked in now:
4798 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
4799 nindy-share/nindy.c: lint
4800 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
4801 register values coming back from the target; we store values
4802 in target byte order everywhere.
4804 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
4806 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
4808 * valprint.c (cplus_val_print, val_print_fields): New functions,
4809 which print C++ objects. They conspire to avoid printing a
4810 virtual base class more than once, following all the twists and
4811 turns of C++ virtual base rules.
4812 (val_print): Call the above rather than do it by hand.
4814 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
4815 symbol file, not for added files like shared libs. This really
4816 needs to be generalized to a timestamp per file.
4818 * core.c (cleanup_core): Avoid coredump if no core file.
4820 * config.gdb: Accept -host or -target in place of +host or
4823 * coffread.c (find_linenos): Avoid desupported BFD interface
4824 to line numbers. We still read them manually rather than using
4825 BFD's "generic" features.
4827 * gdbrc.tex, threecol.tex: Add GDB reference card and its
4829 Makefile.dist: Add refcard to OTHERS list for creating tar files.
4831 * Makefile.dist: Eliminate use of $< in explicit targets.
4833 * readline/Makefile: Use $< rather than $*.c, which does not
4834 include the VPATH in GNU Make.
4836 * tconfig/i960-bout, tconfig/i960-coff: These are identical
4837 copies of tconfig/i960, added for global configuration
4838 compatability. All i960 versions can read both coff and b.out.
4840 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
4841 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
4844 * TODO: Think of more things to do.
4846 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
4848 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
4849 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
4850 64-bit float conversion.
4852 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
4853 equivalent to sun?os4 so global config works.
4855 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
4857 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
4859 * main.c: Only declare linesize once; declare pagesize not at
4860 all, since it is never used.
4861 (main): Clear newly allocated line before it is used.
4863 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
4865 Further stabilization for the Intel 960.
4867 * Makefile.dist: Parameterize the location of the "include"
4868 and "bfd" directories, as well as "getopt". Add symfile.c.
4869 Link in both dbxread and coffread. Fix up "make depend" to
4870 rewack the locations of include, bfd, and getopt in its output.
4872 * README: Document moving include files, improve some of
4875 * coffread.c: Move common code out to symfile.c. Change
4876 symbol_file_command style interface to use new *_symfile_init
4877 and *_symfile_read interface under BFD. Use BFD internal
4878 info to locate line table, symbols, etc.
4880 * core.c (core_fetch_registers): Rename to get_core_registers
4881 to avoid confusion with fetch_core_registers.
4882 (register_addr): Move to coredep.c, which is already machine
4883 dependent. This leaves core.c pretty clean of dependencies.
4885 * coredep.c (register_addr): Accept this routine from core.c.
4887 * dbxread.c: Move common code (with coffread.c, etc) into new
4888 symfile.c. Each psymtab now contains a pointer to the
4889 format-dependent function that knows how to read it in. Make
4891 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
4892 (process_one_symbol): Add code to complain about a "compiler bug
4893 we muzzle here", if we actually see it.
4895 * eval.c (evaluate_subexp): Insert missing "break" statements
4896 in code that determines whether a variable is an lvalue in
4897 memory, register, or whatever. I detected this via a compiler
4898 bug in which it *almost* mashed out the whole switch statement.
4900 * gdb-int.texinfo: Add minor sections on configuring gdb for
4901 release, and about the README file.
4903 * infcmd.c (registers_info): Fix formatting somewhat. Still
4904 not as pretty as before, but it handles byte swapping.
4906 * remote-nindy.c: If data cache routines are interrupted while
4907 waiting for the remote end, be sure that any uninitialized cache
4908 blocks are on the free list, not on the valid list!
4910 * symfile.h: Flesh out this header file with all the various
4911 routines and variables that have been merged in from dbxread.c
4912 coffread.c, and symtab.c to symfile.c.
4914 * symfile.c: New file, containing code common to dbxread.c,
4915 coffread.c, and some code from symtab.c. All generic code for
4916 reading symbol files should be in here now.
4917 (unrecord_misc_function): Remove unused function.
4919 * symtab.h: Remove file-reading things to symfile.h.
4921 * symtab.c: Remove file-reading things to symfile.c.
4923 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
4924 to decode i960 fault types.
4926 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
4927 target.c: Change type of the "resume" function from int to void,
4928 since its result was never used.
4930 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
4932 * main.c: Replace "stupid" with "caution"; you now "set caution
4935 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
4937 * infcmd.c (do_registers_info): Call val_print to deal with the
4938 byte order of the registers being printed. FIXME, this makes
4939 the formatting of the output uglier.
4941 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
4942 defined, call it for signals the debugger doesn't itself use.
4943 The i960 uses this for more detailed fault information.
4945 * remote.c (remote_open): If arg is null, print help rather than
4948 * sparc-xdep.c (register_valid): Avoid declaring size, since
4949 various modules will think of various sizes depending on the
4950 architecture of their tm-file. FIXME, we need protection against
4951 actually entering one of those modules, which would clobber
4952 storage if not for the target architecture compiled into gdb.
4954 * stack.c (up_command, down_command): Always print the frame
4956 (up_silently_command, down_silently_command): New commands
4959 * i960-pinsn.c (reg), i960-tdep.c: Lint.
4961 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
4962 more parameters than it used to.
4964 * findvar.c (registers): Increase slop to 256 bytes, which should
4965 protect us against even most RISC machines with large register
4967 (locate_var_value): Move declaration inside related ifdef.
4969 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
4970 throughout, to avoid throwing away buffered input from the board.
4971 (nindy_wait): Supply_register takes addr_of_value, not value.
4972 (i960_print_fault): Renamed from i80960_fault.
4973 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
4974 (nindy_store_registers): Avoid regs_changed stuff, just stuff
4976 (nindy_create_inferior): Don't bother to write PC_REGNUM since
4977 we can set the PC in the call to proceed(). Unpush nindy_ops
4978 before pushing it on top, to avoid message to user. Eliminate
4979 commentary from Unix machines that just misleads here.
4980 (reset_command): Fix error message to suggest target command.
4982 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
4984 Release 3.92.5 as frozen.
4986 Stabilize the merged release...with help from lint, Saber C,
4989 Everywhere: Add include files needed to declare return types
4990 of functions called.
4992 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
4994 * breakpoint.h: Add undeclared breakpoint functions, and some
4995 functions for display handling since I couldn't think of a better
4998 * breakpoint.c (insert_breakpoints): Make code for disabling
4999 shared library bkpts more likely to work. It's used when we
5000 rerun a program and stop before the shared library has been
5002 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
5003 cast from pointer, so it squeezes through catch_errors.
5004 (bpstat_stop_status): Fix logic broken some time ago. We now
5005 always create a bpstat if the stop address matches a breakpoint,
5006 even if we don't stop there -- just like the old code used to do
5007 before I got my fingers into it (sigh).
5008 (breakpoint_1): Print "ignore count" after "stop only if"
5009 condition, since that's how it actually works.
5010 (mention): Handle watchpoints as well as breakpoints.
5011 (watch_command): use set_raw_breakpoint and mention to do most
5012 of the work (and initialize all the fields!). Only pass one
5013 arg to parse_c_expression, since that's all it takes.
5015 * command.c (not_just_help_class_command): Rename arg to args
5016 since we ignore "unused argument" warnings on vars named "args".
5017 inflow.c (child_terminal_info): ditto.
5018 infptrace.c (kill_inferior): ditto
5019 main.c (catch_errors, version_info, quit_command, pwd_command,
5020 source_command, dump_me_command, editing_info,
5021 set_history_size_command, set_history, show_history,
5023 stack.c (locals_info): ditto
5024 target.c (target_files_info): ditto
5025 valprint.c (set_input_radix, set_output_radix): ditto
5027 * core.c: Remove old variables for handling core and exec file
5028 sections (data_start, data_end, stack_start, stack_end,
5029 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
5030 text_end, exec_data_start, exec_data_end, text_offset,
5031 exec_data_offset, data_offset, stack_offset). They're
5032 superseded the more general build_section_table and
5034 (get_exec_file): Mention the `file' command.
5035 (read_memory_check): Rename to memory_error, and only call it
5036 in the case of an actual error.
5037 (read_memory, write_memory): call memory_error.
5038 (core_fetch_registers): Register section name is ".reg".
5040 coredep.c: Remove a bunch of crud now that all this file does
5041 is pull the registers out of a core file.
5042 (fetch_core_registers): Rewrite to actually work, I hope.
5044 dbxread.c: Use a.out.gnu.h, not system a.out, now.
5045 Replace index() with strchr(). Remove all the pre-BFD macro
5046 definitions for accessing the symbol file.
5047 (struct dbx_symfile_info): Encapsulate the information that
5048 dbx_symfile_init needs to pass to dbx_symfile_read in this
5051 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
5052 dbx_symfile_discard): Rearrange symbol file reading to divide
5053 the format-specific part from the format-independent part,
5054 leaving the format-independent part such as file name expansion
5055 and opening in symtab.c. This replaces
5056 partial_symbol_file_open and partial_symbol_file_read.
5057 Symbol_file_read, add_file, add_file_target_command,
5058 add_file_addr_command move to symtab.c. Pass an explicit
5059 "mainline" flag for when reading the main symbol table, rather
5060 than relying on the offset address to be zero or nonzero.
5062 (dbx_symfile_read): Don't allow void *'s to be printed as
5064 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
5065 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
5066 macro" debug version really work.
5067 (read_dbx_symtab): Remove unref'd parameter inclink.
5068 Avoid swapping N_SLINE symbols, for speed.
5069 Merge N_TEXT!N_EXT case with the other external symbol
5070 definitions' case. Add comments.
5071 (start_psymtab): Allocate the symfile name in the psymtab on
5072 the psymbol_obstack, rather than using the caller's storage.
5073 (end_psymtab): Only allocate a dependencies list if there are
5075 (psymtab_to_symtab_2): Use BFD when reopening file to read
5076 its symbols for real.
5077 (read_struct_type): Add FIXME comments where it needs work
5079 (read_huge_number): Add FIXME about overflows.
5080 (read_range_type): Add FIXME about comparing a long to 1<<32.
5082 * coffread.c: Minor changes to move things closer to the new
5083 regime with symtab.c and dbxread.c Major work is still needed
5086 * exec.c (exec_file_command): Remove old variables (see core.c
5088 (xfer_memory): If memory transfer is right at the end of a
5089 section, don't lose.
5091 * findvar.c (get_saved_register): If value is in a real
5092 register, LVAL is lval_register, not lval_memory.
5094 frame.h: Declare print_sel_frame and record_selected_frame.
5096 gdb-int.texinfo: New file, for GDB internals documentation.
5097 Very simple, unformatted doc of cleanups is there for now.
5099 gdbcore.h: Remove obsolete variables that described a.out
5100 section addresses and offsets. (See core.c above.)
5101 Declare fetch_core_registers and registers_fetched.
5103 getopt.c: Declare char *alloca(); even on SPARC.
5105 infcmd.c (run_command): Call target_kill rather than
5107 (step_command, next_command, stepi_command, nexti_command):
5108 Declare from_tty parameter even though we don't use it.
5109 (run_stack_dummy): argument BUFFER is a char array, not
5110 a pointer to REGISTER_TYPE.
5111 (finish_command): using_struct_return needed a value *,
5112 not a struct symbol *.
5114 * infptrace.c (child_xfer_memory): To avoid dependency on
5115 where sections are in memory, try PT_WRITE_D and if that fails,
5116 try PT_WRITE_I. Most Unixes don't care which you use.
5118 * infrun.c (step_resume_break_shadow): Change to array to
5119 match other breakpoint shadow storage.
5120 (clear_proceed_status): Pass address of bpstat to
5121 bpstat_clear, not the bpstat itself.
5122 (child_create_inferior): FIXME comment about if the child
5124 (start_inferior): Remove old function.
5125 (child_open): Use target_kill rather than kill_inferior.
5126 (wait_for_inferior): Ditto.
5127 (insert_step_breakpoint, remote_step_breakpoint): Use
5128 new step_resume_break_shadow.
5130 * inftarg.c (child_wait): If all child processes die,
5131 pretend that the one being waited for exited with signal 42.
5133 * main.c (command_line_input): When scanning for comments,
5134 don't coredump on unclosed quotes.
5135 (quit_command): Use target_kill rther than kill_inferior.
5136 (_initialize_main): Rename class_user from "user" to
5139 * printcmd.c (print_command_1): Initialize "fmt" if no format
5140 is specified by the user.
5141 (print_frame_args): Only add to args_printed if we are
5142 actually fetching args from the stack (avoiding undefined
5144 (_initialize_printcmd): Remove bogus \{ from string.
5146 * remote-eb.c (eb_open): Avoid coredump on no argument.
5148 * remote-nindy.c: Bring out of Intel environment into new
5149 target environment. Remove all conditional compilation on
5150 I80960. Massive hacking throughout.
5151 (nindy_xfer_inferior_memory): New routine stolen from
5153 (nindy_create_inferior): New routine pieced together, probably
5154 not quite working yet.
5155 (nindy_ops): New target_ops struct for nindy.
5157 * remote-vx.c: Use write_memory rather than target_write_memory
5158 to get error checking.
5159 (vx_add_file_command, vx_open): Use symbol_file_add rather than
5161 (vx_create_inferior): Use target_terminal_ours...
5163 * signame.c (_initialize_signame): Always initialize, since
5164 we need the table for things other than psignal.
5166 * solib.c (solib_add): Use symbol_file_add, not add_file.
5167 (solib_address): Return boolean result rather than struct
5168 pointer which nobody else knows the type of.
5170 * sparc-tdep.c, valops.c: Use write_memory rather than
5171 target_write_memory, to get error checking.
5173 * stack.c (locals_info, catch_info, args_info,
5174 get_selected_block, frame_command, up_command): Use
5175 target_has_stack, rather than have_inferior_p or
5178 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
5180 * symfile.h: New file, defining the interface between the
5181 generic and object-file-specific symbol reading code.
5183 * symtab.c: Move generic symbol-reading interface to symtab.c,
5184 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
5185 table to map BFD targets to symbol-reading modules in GDB.
5186 Change index to strchr.
5187 (lookup_struct_elt_type): Use error() rather than hand-made
5188 simulations thereof.
5189 (lookup_partial_symbol): Speedup slightly when length == 0.
5190 (symbol_file_add): New function.
5191 (symbol_file_command): Call it.
5192 (symfile_open, symfile_init): New function.
5193 (add_file_target_command, add_file_addr_command): moved from
5196 * target.c (target_command): use target_kill.
5198 * target.h (target_files_info): Don't declare, never called
5201 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
5202 files to determine stack end address.
5204 * valarith.c (value_x_binop, value_x_unop): Change error message
5205 to be more useful. Pass proper argument to value_struct_elt.
5207 * valops.c (value_assign): FIXME comment that long long
5208 bitfields will break here.
5210 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
5211 Update `make saber_gdb' to work better.
5213 * TODO: A woman's work is never done.
5215 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
5216 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
5217 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
5218 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
5219 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
5220 valops.c, valprint.c, exec.c: Lint.
5223 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
5225 Continuing Intel 960 port merge of GDB.
5227 * Makefile.dist: Merge i960 "nindy-share" files. Rename
5228 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
5229 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
5230 Wack over "make depend" so it handles files in subdirectories
5231 vx-share, nindy-share, bfd, and in the current directory.
5233 * blockframe.c (get_prev_frame_info): Remove fatal error
5234 if stack not defined.
5236 * core.c (core_open, core_detach): New functions that handle
5237 the old "core-file" command as "target core" and "detach" instead.
5238 (core_file_command): Call them.
5239 (core_xfer_memory): Use common routine xfer_memory.
5241 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
5242 dbxread now uses bfd for everything but symbol reading itself.
5243 BFD internals are used to drag out the relevant file offsets.
5244 (partial_symbol_file_open): Change args all around for BFD.
5246 * symtab.c: Rename "value" to "val" everywhere, so we can
5248 (symbol_file_command): New command, moved from dbxread.c
5249 and coffread.c. It uses BFD to read the file, then vectors
5250 based on its type, to dbx or coff symbol readers.
5251 * symtab.h: Extern a few vars for symbol_file_command.
5253 * target.h: Breakpoint takes a char * save area, not a char **.
5255 * valprint.c (val_print): When unpacking bitfields, offset
5256 the address in gdb of the value, if it is declared with a shorter
5257 type. Remove the last "runtime kludge test" of host byte order.
5259 * utils.c: Remove old my_bfd_read routine.
5261 * stack.c (frame_info): Use target_has_stack. Print program counter
5262 register's actual name rather than "pc", since it's called the
5263 "ip" (instruction pointer) on the i960 (sigh).
5265 * target.c (target_command): Add command for selecting a target
5266 type and calling its open routine. This is used for initiating
5267 communication with a particular target, in a generic way.
5269 * tm-i960.h: Update for modern gdb. Remove semicolons from
5270 various macros. Handle reading struct return convention, and
5271 error-out attempts to return structs with the "return" command.
5272 Be sure gdb doesn't think we know how to call functions in the
5275 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
5276 to i960_xxx in lower case.
5277 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
5278 not being defined yet.
5280 * remote.c (remote_open): Call start_remote to initialize
5281 wait_for_inferior during open.
5282 (remote_xfer_inferior_memory): Return length written rather
5285 * remote-vx.c (target_command -> vx_open): Use new generic
5287 * remote-eb.c, inftarg.c, exec.c: ditto.
5289 * infrun.c: Fix comments.
5290 (attach_program -> child_open): Use new generic target command.
5291 (wait_for_inferior): Clear saved register values before target_wait,
5292 so target_wait can set some of them if convenient.
5294 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
5295 Return success indicator, not void.
5296 (child_xfer_memory): Avoid fetching initial word if we'll
5297 overwrite it anyway.
5299 * infcmd.c (attach_command): Use new generic target open routine.
5300 (_initialize_infcmd): Update doc on attach and detach commands.
5301 (do_registers_info): Merge in a byte-order problem as a FIXME
5304 * findvar.c (find_saved_register): Avoid problem in current frame.
5305 (read_relative_register): Ditto.
5306 (write_register): Convert byte order on the way out.
5308 * exec.c (file_command): Add.
5309 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
5310 (xfer_memory): Common function between core_xfer_memory and
5312 (exec_xfer_memory): Use it.
5314 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
5316 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
5317 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
5318 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
5320 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
5322 Merge Intel 960 port of gdb, continuing...
5324 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
5325 symbol_file_command): Pass from_tty arg to hush 'em up.
5327 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
5328 Add magic numbers for 960 COFF format.
5330 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
5332 Merge Intel 960 port of gdb, from Intel "1.2" release.

5356 Thu Apr 19 09:54:28 PDT 1990
5357 Add 'reset' command.
5359 Wed Apr 18 09:48:07 PDT 1990
5360 After opening remote tty, wait for 1 second to go by without input
5361 from it before trying to talk to NINDY (fixes problems with the
5362 Heurikon HK80/V960E).
5364 Mon Apr 4 16:33:05 PDT 1990
5365 Some output was not being suppressed in 'batch' mode.
5367 Thu Mar 22 15:31:11 PST 1990
5368 Ask user if old symbol table should be deleted when new file is
5371 Allow user to run a program downloaded before gdb960 was brought up.
5373 Correct "exec-file" help message for i80960 context.

5400 Added 960CA disassembly support.
5402 To simplify maintenance:
5403 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
5405 - eliminated opcode.h: incorporates tables into i960-pinsn.c
5406 - moved 960-specific routines from i960-pinsn.c to i960-md.c
5407 - made disassembly interface identical to that in gdmp960.
5411 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
5413 * target.h: Allow targets to stack. Add target_has_memory,
5414 _registers, etc. Restructure memory access and "info files"
5415 to walk the target stack.
5416 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
5417 target.c: Change tables to match target.h.
5418 * inflow.c (child_mourn_inferior): pop child_ops.
5419 (generic_mourn_inferior): Use new has_stack flag.
5420 * infptrace.c (child_xfer_memory): New memory regime.
5421 * inftarg.c (child_files_info): New "info files" regime.
5422 * remote-eb.c: New memory regime, new info files.
5423 * remote-vx.c: New memory regime, new info files. Now use
5424 separate targets for VxWorks attachment to machine, and
5425 actually running a process under VxWorks, since one has
5426 stack & execution & regs and the other doesn't.
5427 * remote.c: New memory regime, new info files.
5428 * sparc-xdep.c (fetch_core-registers): New memory regime.
5429 * target.c: New routines and support for stacked targets,
5430 new memory regime, new info files regime.
5433 Generalize section handling for an arbitrary number of sections,
5434 including use of the new BFD (binary file) library.
5435 * gdbcore.h: Add struct section_table.
5436 * exec.c (build_section_table): Iterate all sections and
5437 record what gdb needs to know about them.
5438 (exec_command): Use it.
5439 (exec_xfer_memory): Use the table.
5440 (exec_files_info): Print the table.
5441 * core.c (core_file_command, core_xfer_memory, core_files_info):
5443 * source.c (find_source_lines): Use bfd_get_mtime.
5444 * dbxread.c: Quick changes to make it compile with new BFD.
5445 * utils.c (error): Avoid using bfd_error in generic routines.
5447 * core.c (core_fetch_registers): Get from the ".regs" section of
5449 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
5451 * inferior.h (attach_flag): Export.
5452 * infcmd.c (run_command): use new target_create_inferior.
5453 * infrun.c (child_create_inferior): Don't return result.
5454 * Makefile.dist (VERSION): 3.91.4.
5456 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
5458 * breakpoint.c (bpstat_num): Handle breakpoints which have
5459 since been deleted, such as temporary breakpoints.
5460 infcmd.c (program_info): ditto.
5462 * core.c (core_file_command): Display the frame where the core
5467 * remote-vx.c (target_command): Merge in target command from
5468 targ-vx.c. A few other cleanups.
5470 * TODO, Projects: Lots more stuff to do...
5472 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
5474 Massive changes to wall off the remote-debugging interface
5475 behind a function vector. The port to handle VxWorks targets
5476 is also part of this.
5478 All files: Replace references to renamed functions,
5479 remove references to remote_debugging, remove references to
5480 have_include_file, have_core_file in favor of target_has_stack,
5481 target_has_memory, etc.
5483 * Modularize the breakpoint interface.
5484 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
5485 a breakpoint instruction.
5486 breakpoint.c: struct breakpoint's shadow_contents now sized as
5488 (insert_breakpoints): Vector to target to install breakpoints.
5489 (remove_breakpoints): Vector to target here too.
5490 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
5491 sparc-tdep.c (single_step): Use new breakpoint interface for
5492 the single-step breakpoints.
5493 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
5494 New file, contains routines to insert and remove breakpoints by
5495 reading out the old contents and later replacing them. This is
5496 how ptrace breakpoints work, and many remote systems as well.
5498 * tm-vxworks68.h: New config file, overrides a few things for
5499 Wind River's preferences.
5501 * target.h: New file, for transfer vector used to talk to the
5502 inferior (child, attached, core, exec, remote, etc). All accesses
5503 to the thing being debugged should come through these vectors.
5504 target.c: New file, routines to handle transfer vector.
5505 (various files): Add transfer vectors XXX_ops for the various
5506 targets and pseudo-targets (core files, etc) we support.
5508 * breakpoint.c (bpstat_stop_status): Further explorations of
5509 watchpoints and why things don't work all the time.
5510 (bpstat_alloc): New fn to allocate a bpstat and chain it.
5512 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
5513 the local gdbinit if it doesn't already have it.
5515 * core.c (core_ops): add and install.
5516 Allow core debugging without exec file.
5518 * dbxread.c (free_and_init_header_files): Merge two fns.
5519 (end_symtab): Free named symbol table when a new version comes in.
5520 (read_dbx_symtab): Relocate all kinds of symbols with base
5521 address. First step toward handling different text, data, bss
5523 (add_file_addr_command): Renamed add_file_command.
5524 (add_file_command): Vector to remote handler.
5525 Add "load" as an alias for "add-file" command.
5527 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
5528 non-returning functions.
5530 * exec.c: Add exec_ops, and push it as a target when an exec
5533 * infcmd.c (run_command): Pass executable file name and arg list
5534 separately when starting an inferior. Permit "run" when no exec
5535 file is specified, for VxWorks.
5536 (detach_command): Move to child_detach in inftarg.c.
5538 * inftarg.c: New file. Unix-child-specific routines, and the
5539 child_ops structure.
5541 * inferior.h (registers): Export "registers" as the way for
5542 target dependent register handlers to find gdb's local copy of
5543 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
5544 since it is now used by places that want wait_for_inferior to
5545 handle the grunge but want to see every trap from the inferior.
5547 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
5548 Eliminate remote_debugging hooks in terminal handling.
5550 * infrun.c: Replace start_inferior with child_create_inferior.
5551 Move all the hair of Unix shells and ptrace idiosyncracies into
5552 child_create_inferior, so remote handlers don't have to deal.
5553 Remove running_in_shell. Rename stop_after_attach to
5554 stop_soon_quietly, and use it in a few other places where we want
5555 to just call wait_for_inferior and get control back on the first
5556 trap. trap_expected now never takes a value > 1.
5557 (init_wait_for_inferior): Initialize static vars when a new
5560 main.c (gdbinit): Add new hook for .gdbinit file name, let
5561 it be overridden by config files as GDBINIT_FILENAME.
5562 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
5563 Both of these are used for VxWorks gdb.
5565 mcheck.c: rename include file "gmalloc.c" to avoid problems
5566 with system include file "malloc.c".
5568 param-no-tm.h: New include file, same as param.h but does not
5569 include the default "tm.h" file. This is used in files where
5570 the target is known, e.g. remote-eb.c or sparc-xdep.c.
5572 param.h: Now just a shell that includes tm.h and param-no-tm.h.
5574 remote-vx.c: New file, VxWorks remote debugging support. Uses
5575 RPC routines that are shared with the target system, in directory
5578 remote.c: Vectorize remote interface.
5580 source.c: Globalize source_path, and make an alias "l" for "list"
5581 since we now have the "load" command.
5583 sparc-xdep.c: Use new param-no-tm.h.
5585 symmisc.c (free_named_symtab): Add new function from Wind River.
5586 However, ifdef it out for now while we think about what it should
5589 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
5591 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
5592 non-Unix-children handle this with their own code in the target
5595 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
5596 source and target lists. Add vx-share to default list of include
5597 directories. Add new files to src and target lists: mem-break,
5598 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
5599 ${srcdir} versions of munch and createtags are used.
5601 * valops.c (find_function_addr): Split out of call_function.
5602 (call_function_by_hand): Rename call_function; this function
5603 calls functions in the target by laboriously patching the target
5604 word-by-word with the right stack, args, regs, etc.
5607 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
5609 Handle AMD 29000 a bit better.
5611 * remote-eb.c (readchar): Mask received char log to make it readable.
5612 (remote_start): Pass arguments down to executing program.
5613 Make startaddr unsigned.
5614 infrun.c (start_inferior): Accept args, pass them to
5616 infcmd.c (run_command): Pass args down to start_inferior.
5618 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
5619 the target object file format.
5620 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
5622 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
5623 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
5625 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
5627 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
5628 * TODO: We did a few things, we have more to do though.
5630 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
5631 * inflow.c (inferior_died): Clear deferred stores.
5633 * Debug problems with dummy frames and calls to the inferior.
5634 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
5635 * sparc-tdep.c (do_restore_insn): Simplify.
5636 (sparc_frame_find_saved_regs): Simplify and fix what we find.
5637 (sparc_push_dummy_frame): Simplify and fix what we push.
5638 (sparc_pop_frame): Slightly more hair here, deciding whether
5639 we are restoring a saved PC or returning to a return address in %i7.
5640 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
5642 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
5643 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
5644 * obstack.h (chunkfun): ditto.
5645 * defs.h (xmalloc, xrealloc): ditto
5647 * utils.c (quit): Grab the terminal from the child if necessary.
5649 * inflow.c (term_status_command): Rename to term_info, change
5652 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
5653 (is_delayed_branch): Speed up.
5654 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
5655 Still missing some float ops, and needs testing.
5657 * Support for input and output radixes other than base 10
5658 * defs.h (input_radix, output_radix): Declare.
5659 * expread.y (yyparse, parse_number): Handle changes of input
5660 radix, and ambiguous names-or-numbers in radixes >10.
5661 * printcmd.c (print_scalar_formatted): Print formatted hex
5662 numbers in varying column widths.
5663 * valprint.c (val_print): Use output_format to print scalar ints.
5664 (set_input_radix, set_output_radix, set_radix): Create.
5665 (set_output_radix): Set output_format from output_radix.
5666 (_initialize_valprint): add `set radix' but leave the others off.
5668 * main.c (execute_command): Let stupid questions be turned off.
5669 (_initialize_main): Handle "set stupidity", etc.
5671 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
5672 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
5674 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
5676 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
5677 bfd stuff is still screwed up, but with some manual work, it
5680 * breakpoint.c (bpstat_do_actions): Start over if a command
5681 proceeds the inferior, since the inferior will have stopped and
5682 will need to have its new stop-actions taken care of.
5684 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
5685 compiler fits, simplify it.
5687 * gdb.texinfo (directory command): Doc new dir command.
5688 source.c (directory_command): "dir" now puts things on the front
5689 of the path, moves dups up front, and handles multiple names
5690 on the command line, inserting each one in order. It also
5691 blows away cached line and full_filename info.
5693 * stack.c (backtrace_command): Skip "more stack frames follow"
5696 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
5697 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
5698 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
5699 The only odd one was Gould NP1, which had defined vprintf to
5702 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
5703 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
5704 variable, inspect_it.
5705 valprint.c (print_string, val_print): Use the global inspect_it
5706 to indicate whether to print in Epoch style or normal style.
5708 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
5710 * printcmd.c (call_command): add an alias for the "print" command
5711 which runs expressions and doesn't print the result if void.
5712 (print_command_1): implement it.
5714 * command.c: Remove #if 0'd code. Initialize all the fields
5715 in add_cmd (). Rename do_nothing_command to
5716 not_just_help_class_command, and make it externally visible.
5717 command.h: add user_commands to struct.
5718 * main.c (define_command): Don't overload c->function with a char
5719 string as well as a function pointer.
5721 * eval.c (evaluate_subexp): Reinstall tiemann changes to
5722 calling convention of value_struct_elt () that got dropped in
5725 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
5726 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
5728 * tm-sparc.h (POP_FRAME): replace some constants with defines.
5730 * sparc-xdep.c (store_inferior_registers): defer stores to regs
5731 until a good time (e.g. when we are about to run the child),
5732 saving ptrace calls.
5733 * infrun.c (proceed): handle DO_DEFERRED_STORES.
5734 * tm-sparc.h: define DO_DEFERRED_STORES.
5736 * sparc-xdep.c (store_inferior_registers): when storing float
5737 registers, don't store stack regs too. When storing the SP,
5738 however, DO store the stack regs too. This fixes a bug in which
5739 the dummy frame is not recognized when a call_function finishes,
5740 because its frame pointer (in the stack regs) was never
5742 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
5743 even though we don't know how to read them from an inferior.
5744 valops.c (call_function): Comment about storing SP.
5746 * infrun.c (save_inferior_status): Save away the original bpstat
5747 chain so it can be restored later. Install the copied version for
5748 use by whoever saved the status. It will be blow away by
5749 restore_inferior_status, and the original chain restored. This is
5750 important for people who have pointers into the original.
5752 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
5753 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
5754 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
5757 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
5759 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
5760 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
5761 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
5763 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
5765 * Merge Mike Tiemann's multiple inheritance changes from Sun.
5766 Store the baseclasses in a type struct starting from array element
5767 0 rather than from the unusual array element 1.
5769 dbxread.c: the above.
5770 (virtual_context): Add
5771 Read new debug information about which virtual function table
5772 a virtual function is from, and store it in fn_field.fcontext.
5774 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
5775 TYPE_FN_FIELD_STATIC_P.
5777 symtab.c: the above.
5778 valops.c: the above. Handle pointer casts of object *'s.
5779 (search_struct_method): Add.
5780 (value_struct_elt): First arg is now a pointer to a value, and is
5783 valprint.c: the above.
5784 values.c (value_virtual_fn_field): Add type arg. Handle
5785 offsetting to the proper object when calling virtual fns.
5787 (baseclass_addr): Add valuep arg.
5789 * README: Document the current state of BFD config (missing).
5790 * TODO, ChangeLog, Makefile.dist: Roll version.
5791 * WHATS.NEW: Add summary of changes since 3.5.
5793 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
5795 * dbxread.c (read_struct_type): Clear bit vectors whenever
5797 symtab.c (B_CLRALL): define.
5799 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
5800 using == rather than =. Huh... This fixes the dreaded problem
5801 wherein builtin_type_int becomes TYPE_CODE_FLT.
5803 * core.c (info_files): Show the inferior pid.
5805 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
5806 already knows how to look in the source directory.
5808 * Remove psymtab hair from many places. Remove duplicated code
5809 for searching symbol tables. Hide psymtabs from most places.
5810 Make it fast to get from a psymtab to its symtab.
5812 blockframe.c (blockvector_for_pc): Remove psymtab hair.
5813 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5814 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5815 dbxread.c: export psymtab_to_symtab, make it work if called N times.
5816 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
5817 new symtab completely. New psymtabs get symtab pointer
5818 initialized to zero. Remove MI warning printf.
5819 symtab.h: Comments. Add psymtab to symtab pointer.
5820 (PSYMTAB_TO_SYMTAB): New macro.
5821 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
5822 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
5824 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
5826 (print_frame_info): Avoid special-casing symbols that have not yet
5829 * source.c (open_source_file): Quick path if we have already
5830 located the source file by its full name.
5832 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
5833 find_pc_psymtab. When a name is found in the misc function
5834 vector, search the symbol table for its mangled name, not the
5835 name that the user typed.
5837 * bfd.h: Fix missing comment terminators, make #endifs match.
5839 * valarith.c (value_less): Handle unsigned int comparisons.
5840 Add FIXME about pointer compares, which assume host and target
5841 pointers are the same.
5843 * command.c (do_nothing_command): lint
5844 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
5845 fix comments on debug symbol format for visibility. Actually set
5846 visibility of symbols.
5847 main.c (echo_command): lint; use <readline/history.h>.
5848 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
5849 obstack.h (_obstack_blank): Rearrange pointer math to avoid
5850 pointing past end of allocated memory; saber complains.
5851 obstack.h: Declare the external functions that we use.
5852 valarith.h: use <string.h>
5853 solib.c (solib_add): lint.
5855 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
5857 * main.c (initialize_main): Default info_verbose to off, now that
5858 symbol reading is fast.
5859 (quit_command): Avoid clobbering exec_bfd while quitting.
5861 * Initial BFD (binary file diddling library) merger:
5862 coffread.c: Change AOUTHDR to struct exe_hdr.
5864 core.c: initialize initialized data at compile time.
5865 (core_file_command): Move from coredep.c, convert to bfd.
5866 (xfer_core_file): Convert to bfd.
5867 exec.c (exec_file_command): use bfd routines.
5869 mips-tdep.c: Remove exec_file_command and friends.
5872 * coredep.c: (fetch_core_registers) Convert core_file_command to
5873 fetch_core_registers.
5874 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
5876 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
5877 (my_bfd_read): More bogosity, which I don't think we call.
5878 (program_name): Remove this atrocity asap!
5880 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
5883 values.c: allocate_repeat_value was not clearing the
5884 optimized_out field.
5885 (value_static_field): minor stylistic fix (wrong macro was used).
5886 valops.c (value_struct_elt_for_address): didn't work for C++
5889 * signame.c (_initialize_signame): Initialize signal names once.
5891 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
5892 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
5893 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
5895 * remote-eb.c: Support user-settable baud rates on the serial port.
5897 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
5899 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
5901 * tconfig/sun3os4: Remove warning about native assembler,
5902 since it also occurs in the xconfig file.
5904 * findvar.c (registers): Allocate some slop after `registers'
5905 to prevent stray accesses from trashing the next variable.
5907 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
5908 on the sun-3, by changing the #ifdef from `sun3' (which is not
5909 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
5910 vars, which happened to follow `registers' in the executable.
5912 * readline/history.c (history_search): Heed gcc-2's advice
5913 and parenthesize && inside ||).
5915 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
5916 tm-29k.c: Insert FSF copyright headers.
5918 * remote-eb.c: Better comments.
5920 * Makefile.dist: Update to 3.91.6.
5921 * TODO: note PREPARE_TO_STORE problem.
5923 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
5925 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
5927 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
5929 * infrun.c (wait_for_inferior, at end): Don't set up
5930 prev_* if the inferior no longer exists.
5932 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
5933 CANNOT_EXECUTE_STACK.
5934 valops.c (call_function): Use it.
5936 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
5938 * inferior.h (PC_IN_CALL_DUMMY): New macro.
5939 infrun.c (wait_for_inferior, 2 places): Use it.
5941 * values.c (value_being_returned): Only use
5942 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
5944 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
5945 right thing for remote-eb.c.
5947 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
5948 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
5950 * blockframe.c: Put get_frame_saved_regs inside #if !defined
5951 (FRAME_FIND_SAVED_REGS).
5953 * findvar.c ({fetch,store}_registers): Check for
5954 REMOTE_{FETCH_STORE}_REGISTER macro.
5956 * findvar.c (get_saved_register): Add argument lval and
5957 change meaning of argument addr.
5958 findvar.c: Change calls to get_saved_register to reflect
5959 new calling convention.
5960 valops.c (value_assign): Use get_saved_register instead of
5961 find_saved_register.
5963 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5965 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
5966 an (uninitialized) pointer to one. Use "&" when passing it
5969 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5971 * coffread.c (getfilename): Use DGUX x_offset and x_name if
5974 * coffread.c (symbol_file_command): Put semicolon after
5976 Put safe_to_init_tdesc_context in #if defined (TDESC).
5977 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
5978 coffread.c: #include <sys/stat.h>.
5979 (read_coff_symtab): Typo: in_source_files -> in_source_file.
5980 Add missing ')' in check for "lc%" and friends. Remove
5982 Declare read_one_sym() at top of file.
5983 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
5984 MC68WRMAGIC can have the same value without causing a duplicate
5987 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
5989 * Allow a Makefile to be built without building the
5990 tm and xm file links that screw up builds in subdirectories.
5991 This is done with `config.gdb none', then you can do things
5992 like `make gdb.tar.Z'.
5993 * tconfig/none: Config file for no target system
5994 * xconfig/none: Config file for no host system
5995 * config.gdb: If no TM or XM files are called out by the
5996 host or target file, don't make links for them.
5998 * cplus-dem.c: Add documentation.
6000 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
6001 simple error, so the user's gdb doesn't crash due to some object
6002 file problem (e.g. somebody is rebuilding the file out from under
6005 * printcmd.c (print_address_symbolic): demangle the symbol.
6007 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
6008 Motorola copyrights in it. Make "make gdb.tar.Z" work.
6009 (alldeps.mak): sort and uniq all results from this; duplicates
6010 hose gdb.tar.Z link building. Remove RCS files from
6011 tconfig and xconfig. Add config files for sun386. Add
6012 a few odd files to OTHERS and HFILES.
6014 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
6016 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
6017 Roll version number to 3.91.5. Make lint work in bindir.
6019 * README: Document cross-debugging and new file structure.
6021 * blockframe.c: Lint. Include "value.h" to declare read_register.
6022 (find_pc_partial_function): remove duplicate line.
6024 * command.h: Lint. Declare error_no_arg and dont_repeat.
6026 * tm-news.h: Remove inadvertently duplicated stuff.
6028 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
6029 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
6031 * config.gdb: Allow `config.gdb host target' form. Clean
6032 up previous change that printed bogus messages when you just said
6035 * core.c: #include "command.h" for lint.
6038 * main.c: Remove some casts of enums. Lint.
6045 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
6047 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
6048 read it from memory. This will allow us to save ptrace calls
6049 eventually. Changed caller single_step too.
6051 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
6052 that we aren't going to use, saving many ptrace calls, especially
6053 when watchpointing or single stepping. Use some #define's for
6055 (store_inferior_registers): Ditto.
6056 (core_file_command): Use some #define's for constants.
6058 * tm-sparc.h: Add #define's for some register numbers, so we
6059 can eliminate the use of random constants in sparc-xdep.c.
6061 * stack.c (frame_command, print_frame_info, up_command,
6062 down_command) Remove frame_changed, since it
6063 causes a bug and doesn't seem to do anything useful. In some
6064 places it was used as a flag, in others as a stack level (?).
6066 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
6067 default is to use the portable (vprintf) version rather than the
6069 * xm-news.h (MISSING_VPRINTF): Add.
6071 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
6073 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
6075 * Remove stuff that forces -Bstatic linking of gdb, and warnings
6076 about linking debugged programs -Bstatic in the sun?os4 config
6077 files in tconfig and xconfig subdirectories.
6079 * main.c (main): Remove unreached exit(0) now that we exit
6082 * Create TODO file for online bug list. There are too many
6083 "little" bugs to keep track of on paper.
6085 * Change Projects file to refer to bug-gdb@cygnus.com
6086 rather than kingdon@ai.
6088 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
6090 * Makefile.dist (VERSION): 3.91.4 now.
6092 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
6093 (condense_misc_bunches): Add sanity check that misc_count is
6094 the same as the number of symbols in the bunch.
6096 * coffread.c: rename init_misc_bunches. Pass an argument
6097 to condense_misc_bunches (a zero).
6099 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
6100 every time we are called; don't rely on our caller to do it.
6101 (add_file): Remove call to init_misc_bunches.
6103 * mipsread.c: Only warn, don't error, if unknown symbol types.
6104 This keeps an old gdb from falling on its face if it sees newly
6105 extended symbol info. Rename init_misc_bunches.
6107 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
6109 * Merge in changes from Per Bothner for DECstations and other
6110 MIPS stuff. The rest is Bothner speaking:
6112 The next message is a merger of Alessando Forin's mips port with
6113 mine. I've tried to use my good if biased judgment to get
6114 the best of both. It *does* need testing.
6116 Some of the changes are general, *not* mips-specific.
6119 Didn't believe in little-endian bit order.
6120 There are still inconsistencies about whether flags
6121 like BITS_BIG_ENDIAN are integer (#if ...) or
6122 boolean (#ifdef ...). I tried to paper over them.
6124 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
6125 Moved some misc_function code that was common to
6126 {dbx,coff,mips}read.c to symtab.c.
6127 In the process, I think I cleaned things up a bit.
6128 At the same time, moved obsavestring and obconcat to symtab.c.
6131 Removed obsolete condense_addl_misc_bunches (use
6132 condense_misc_bunches(1) instead).
6135 Needed to include <sys/dir>, at least on DECstations.
6137 valops.c, mips-tdep.c, tm-mips.h:
6138 Added PUSH_ARGUMENTS macro to support funny argument-pushing
6139 conventions (when STACK_ALIGN is insufficient).
6140 Needed on mips, where doubles need 8-byte alignment,
6141 but ints only need 4.
6144 Removed cruft that was not being used.
6145 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
6148 Print $ before register-names (I think that makes things a little
6150 Never print two instructions, even if one delays.
6151 Removed hex-disassemble set_cmd. (This is not mips-specific,
6152 so I think the argument is whether it is generally worthwhile or not.
6153 I'm inclined to think not, given how easy it is to
6154 convert between radixes in gdb.)
6157 This is basically Alessando's code.
6158 It doesn't use obstacks; I changed it to use obstacks
6159 in a few minor places where using malloc causes a
6160 memory leak. (Probably, more places could/should be changed.)
6161 I added record_misc_function where it was missing.
6162 In symbol_file_command and add_file_command, I tried
6163 to make the code consistent with more recent versions.
6164 Minor sylistic changes in parse_procedure.
6165 Make a .gdbinfo. psuedo-symbol point back to the real
6166 procedure symbol (using the isym field).
6169 This is basically from my port, but with a lot of details
6170 and a number of routines merged in from Alessando's version.
6171 I basically used my code "raw" backtrace (use heuristics
6172 from the actual code, rather than symbol table info) - though
6173 the idea is Alessandro's. I feel my code is a little cleaner
6174 here, particularly in being a little more flexible, such as being
6175 able to handle gcc-produced code (which it now can).
6176 It also doesn't do frame caching (which is not useful
6177 more recent gdb versions).
6178 I also used my code for push_/pop_dummy, more or less.
6179 I tried to incorporate AF's code for testing sigtramp
6180 while backtracing; I probably got it wrong.
6181 Added mips_print_register, which tries to scrunch as much
6182 information as possible on a screen...
6183 Removed the skip-prologue set_cmd. As with hex-disassemble (see
6184 under mips-pinsn.c), I don't see anything mips-specific here,
6185 and I don't see it being all that useful anyway.
6188 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
6189 Use more register names (rather than hard-cases numbers).
6191 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
6193 * Hack up 3.90.11 changes:
6195 * Makefile.dist (depend): parameterize $(GCC).
6196 Add solib.c and solib.o.
6197 (readline): Fix vpath for both absolute or relative SRCDIR.
6199 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
6200 Also, let the part I didn't understand at least compile so
6201 I can test the rest. FIXME.
6203 * dbxread.c: Fix thinko using strcmp.
6204 (init_psymbol_list): declare static.
6205 (partial_symbol_file_open): Comment cleanups better, avoid
6206 cleaning up the string table since the caller will do that.
6207 Move the stat for mod time into symbol_file_command, temporarily.
6208 (There should be a mod time for each symbol file, eventually,
6209 to control its rereading. FIXME.)
6211 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
6212 SunOS, which gives error for shared libs otherwise. (From
6213 Schaefer, probably FIXME needs work for portability.)
6215 * solib.c: Move #include "param.h" to work.
6216 Lowercase all the Uppercase Letters In the Messages.
6217 (find_solib): Clean up inferior_so_name for debug printouts.
6218 Allow no argument, to mean all shared libraries.
6220 * symmisc.c: include param.h to get CLEAR_SOLIB.
6222 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
6224 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
6225 to 3.90.11. ChangeLog entries below are from this.
6227 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
6231 * Makefile.dist (HFILES): Add tm-sunos.h.
6233 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6237 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
6239 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
6241 * sparc-opcode.h Added single-operand version of rett.
6243 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6245 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
6246 Put parens around gcc_p in expansion.
6248 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
6250 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
6252 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6254 * Changes for Sun shared libraries:
6255 blockframe.c (find_pc_partial_function): If a non-text symbol
6256 is found, set *address = pc - FUNCTION_START_OFFSET.
6257 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
6258 Disable breakpoints instead of giving an error.
6259 source.c (select_source_symtab): Initialize cs_pst.
6260 symmisc.c: Call CLEAR_SOLIB if defined.
6261 symtab.h: Make text{low,high} CORE_ADDR not int.
6262 (psymtab): New field addr.
6264 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
6265 (record_misc_function): Give correct type for N_DATA symbols.
6266 (condense_misc_bunches): do "misc_function_count = j" regardless
6268 Take code which is shared between symbol_file_command and
6269 add_file_command and put it into partial_symbol_file_{open,read}.
6270 Split add_file_command into add_file_command and add_file.
6271 Make psymtab_to_symtab read in the string table if the file
6273 Two new parameters to read_dbx_symtab and start_psymtab.
6274 tm-sunos.h: New file.
6276 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6278 * infcmd.c: Change cont_command to continue_command and "cont"
6281 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6283 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
6285 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
6287 * values.c (USE_STRUCT_CONVENTION): Check for structures of
6288 size 1,2,4,8 rather than size < 8.
6290 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
6291 as necessary, not just once.
6293 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
6295 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6297 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
6299 * tm-news.h: Add CALL_DUMMY_*.
6301 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
6303 * config.gdb: In list_host, list_target, use ${i}, not $i.
6305 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6307 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
6309 * sparc-opcode.h: Change all store floating-point state register
6310 instructions to have the right match & lose fields.
6312 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6314 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
6316 config.gdb: If srcdir != ., create readline directory and
6317 copy a makefile into it.
6319 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
6320 consistency with POSIX.
6322 * breakpoint.c (bpstat_stop_status): Disable watchpoint
6323 when we exit its exp_valid_block.
6325 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
6327 * Makefile.dist: Bump version to 3.91.3.
6329 * Clean up handling of breakpoint commands (somewhat).
6330 Prompted by Tiemann bug report "cont 10" doesn't work any more.
6332 inferior.h: Add breakpoint_proceeded to inferior status struct
6333 and globals; save it and restore it.
6334 (clear_breakpoint_commands): Cleanup, remove old #define.
6336 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
6337 (save_inferior_status, restore_inferior_status): handle it also.
6338 (proceed): Remove earlier code that set breakpoint_proceeded.
6339 It is now set only in clear_proceed_status.
6340 (clear_proceed_status): Cleanup, use bpstat_clear rather
6341 than clear_breakpoint_commands. No callers need the stop_bpstat
6342 between clear_proceed_status and proceed.
6344 infcmd.c: Add breakpoint_proceeded definition and comment.
6345 (cont_command, jump_command, signal_command): Move call to
6346 clear_proceed_status right next to call to proceed.
6348 breakpoint.c (bpstat_do_actions): Avoid clobbering our
6349 caller's argument while running down the chain of breakpoints.
6350 Use new variable "breakpoint_proceeded" to determine when
6351 a command that it executes moves the inferior past the
6353 (bpstat_clear): Handle NULL argument.
6354 (bpstat_clear_actions): Avoid useless call to
6355 breakpoint_auto_delete.
6356 (delete_breakpoint): Clean up bpstat's that are pointing to
6357 the deleted breakpoint from the stop_bpstat chain.
6358 (breakpoint_auto_delete): Simplify.
6360 * Clean up handling of EOF, error on stdin, etc. This was
6361 prompted by a network problem that caused gdb to go into an
6362 infinite loop filling up its malloc'd memory.
6364 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
6365 not clear_breakpoints_commands, which is now gone.
6366 (main): If command_loop returns (e.g. from EOF on stdin), do
6367 a quit_command (looping back to command_loop if quit_command
6368 doesn't really quit).
6369 (command_loop): check result from command_line_input and
6370 exit if it returns NULL, rather than passing the NULL to
6372 (gdb_readline): Free malloc'd result space before returning
6375 * utils.c (query): Handle C-d to mean "yes", just as if the
6376 input was not a terminal. Also avoid infinite loop if EOF
6377 occurs in mid-input-line before newline. This allows
6378 query to be used at EOF on stdin with reasonable results.
6380 * infrun.c (proceed): Set breakpoint_proceeded.
6382 * values.c (value_as_long): Avoid infinite recursion for enums.
6383 (_initialize_values): Fix typo in help msg (kingdon).
6385 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
6386 RL_LIB for linking. This allows -lreadline for linking
6387 and nothing for dependencies, once readline is a real library.
6389 * config.gdb: Jim Kingdon: give useful error message if the
6390 host or target type is not recognized.
6392 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
6393 it just defines it. Dumb, but deal with it.
6395 * Jim Kingdon suggests:
6396 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
6398 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
6400 * Makefile.dist (VERSION): Bump version # to 3.91.2.
6402 * Clean up Bothner's changes.
6404 * blockframe.c (clear_pc_function_cache): New function.
6405 * blockframe.c: remake cache_pc_function_* static.
6406 * dbxread.c (symbol_file_command): remove references to
6407 cache_pc_function_* variables.
6408 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
6409 * printcmd.c: Avoid kludging a global variable (addressprint)
6410 to avoid printing the address of a string twice. Instead,
6411 pass the format letter 's' down low enough that it can be seen
6412 to avoid this problem.
6413 (print_formatted): Pass format arg to value_print.
6414 (restore_addressprint): Remove function.
6415 (do_examine): Avoid hacking addressprint, cleanups and such.
6416 (print_frame_args): Add a comment to a Bothner change.
6417 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
6418 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
6419 to wipe out the values cached in blockframe.c.
6420 * symtab.c (find_method): Add comment saying how big you must
6421 allocate to be "big enough". Per being terse again.
6422 * valprint.c (val_print): Handle format letter "s" to print
6423 strings without addresses. Add comment to vtbl printing code
6424 which casts with wild abandon. Rearrange reference-printing
6426 @0xaddr: value (print w/addressprint)
6427 value (print w/~addressprint)
6428 @0xaddr (parameter lists w/addressprint)
6429 or nothing (parameter lists w/o addressprint)
6431 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
6433 * Merge more changes from Per Bothner:
6435 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
6436 annoying) that I tried to improve it. Here are my suggestions.
6438 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
6441 Do automatic de-reference when taking the address of a reference.
6443 Don't deref_ref when printing parameter lists.
6445 More attempts at treating refernences properly.
6447 In val_print, if deref_ref==0, don't print dangling " = ".
6449 Add COERCE_REF macro, which de-references an REF.
6451 * Merge changes from Per Bothner:
6453 * Fixed (Sony news)-specific configuration problems.
6454 * Fixed other problems with using vanilla pcc and libc (enum problems;
6455 assumption that vsprintf exists).
6456 * Some major speed-ups (finc_pc_partial_function now caches a match;
6457 parsing avoids duplicate symbol_lookup calls).
6458 * Changed handling of baseclasses (no longer use baseclasses field
6459 of struct type, use the first n_baseclasses fields instead).
6460 * Various minor changes/fixes, most C++-related.
6463 Cache the most previous match from find_pc_partial_function.
6464 (Save both low and high ends of matching function's pc range.)
6465 This speeds up the loop of infrun.c:wait_for_inferior quite
6466 a bit, and makes step/next commands much zippier.
6468 Added an enum->int cast (otherwise, some compilers barf).
6470 No longer set baseclass offset to 0, since multiple
6471 inheritance now mostly works.
6472 Added a number of casts, to shut up compiler warnings
6473 (after stabs where made enums, not ints).
6474 When discarding a symbol table (in symbol_file_command),
6475 must clear the cache introduced in blockframe.c.
6476 Don't convert $vtbl_ptr_type to vtbl any more.
6477 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
6478 Mask off sign bit emitted by g++ for virtual table offset.
6479 Set voffset to -1 (not 1) for static member functions.
6481 Changed parsing/lexing of names to avoid doing symbol lookup twice
6482 (once when lexing to determine symbol class, once for real).
6483 Now only call symbol_lookup once. Fields of 'this' win especially big.
6485 Subpress printing addr twice in the case of 'x/s addr'.
6487 lookup_basetype_type is no longer used.
6488 Add find_methods as recursive helper function to decode_line_1.
6489 This allows multiple inheritance to work.
6490 Also, once one or more matches has been found, do not look in
6491 base-classes. (Baseclass methods would be overridden, anyway.)
6493 Removed baseclasses array in struct type.
6494 Instead of using baseclasses[i], use fields[i-1].
6495 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
6496 Changed sign convention of voffset (previous was inconsistent).
6498 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
6500 Used to assume existence of vsprintf. Re-written to not need it
6501 if HAVE_VPRINTF is undefined.
6503 typecmp was too pessimistic. Made it less so.
6505 Don't print space after address.
6506 If vtable points to a misc symbol (with 0 offset), print it,
6507 since that indicates the actual class of the object.
6508 Changed ype_print_derivation_info to use new inheritance
6509 scheme (without baseclasses vector).
6511 In value_primitive_field, fixed some bugs left over from previous set of fixes.
6512 Also, changes needed because TYPE_BASECLASSES were removed.
6514 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
6516 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
6519 If there is no path set, and the symbols don't indicate what directory
6520 a file was compiled in, look in the current directory. But either
6521 a path or a known compilation directory will prevent this.
6524 Three independent bug fixes:
6525 * Remove the #if 0 block that breaks some stuff.
6526 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
6527 adapt gdb to either SunOS 4.0.* or 4.1.
6528 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
6531 Instantiate the class T when looking for methods in it. (Tiemann@sun)
6534 (type_print) Demangle the name being printed.
6535 (type_print_base) Handle botched demangling without coredump (tiemann).
6538 (check_stub_method): Document routine.
6539 (tiemann) fix bug for no-arg functions
6540 Avoid clobbering beyond end of malloc'd storage.
6541 Terminate the argument list properly.
6543 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
6545 * Changes merged by John Gilmore:
6548 In breakpoint_1, use new print_address_symbolic instead
6549 of find_pc_partial_function. (This forces use of assembler-level
6550 addresses, and avoids misleading non-mangled source-level names.)
6552 Generalize ansi argument such that -1 means skip arglist totally.
6553 Removed global variable print_ansi_qualifiers (which made
6554 code non-reentrant), in favor of extra explicit arguments
6555 to internal routines.
6557 Add new helper function print_address_symbolic.
6558 Use find_pc_misc_function instead of find_pc_partial_function
6559 (since we want assembler-level symbols here).
6561 Print unknown function as just "f (...)", not "f (...) (...)".
6562 Use new fputs_demangled explicitly.
6564 Fixed a typing violation (problem: value.h cannot be imported
6565 without renaming many variable in this file).
6566 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
6567 decode_line_1: Moved forward some never-reached code.
6568 Made decode_line_2 skip function prologues correctly.
6570 fputs_filtered should not demangle by default.
6571 Add new fputs_demangled to demangle on demand..
6573 Change value_struct_elt to use value_primitive_field (using recursive
6574 utility function search_struct_field). This allows foo.bar to work
6575 for multiple inheritance (so far only for data fields).
6576 Change check_field in the same way (recursive helper function
6577 to support multiple inheritance).
6578 (Note: there are more of these problems that I haven't fixed.
6579 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
6580 value_of_this: 'this' symbol name is now just "this", note "$this".
6582 Don't print static members.
6583 Avoid printing "members of <type>" if there are none.
6584 Simplified type_print_derivation_info by merging duplicate code.
6585 Remove useless blank lines in type_print_base (ptype command).
6587 Added declaration of new routine value_primitive_field.
6589 Added value_primitive_field which is generalized version of
6590 value_field that can handle multiple inheritance (non-zero offsets etc).
6591 Re-implemented value_field to call value_primitive_field.
6593 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
6595 * infcmd.c -- insert else to avoid 'delete env' coredump when you
6596 delete the whole environment. Karl Berry reported the bug.
6597 * source.c - fix openp to avoid //'s in filenames, which
6598 trigger an Emacs bug causing it to not be able to find files
6599 when running gdb in a window.
6600 * dbxread.c - zap the #if 0 that botches the add-file code.
6601 It seems to work a lot better without all the code commented out.
6603 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
6605 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
6608 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
6610 * Makefile - added a ${CFLAGS} to a couple of entries,
6611 added remote-sa.sparc.c
6612 * added remote.sa-sparc.c, a modification of remote.c
6613 which conducts a dialog directly with the SparcStation prom.
6614 * breakpoint.c, infrun.c, sparcdep.c added
6615 remote_insert_breakpoint(), and remote_remove_breakpoint()
6616 to breakpoint.c instead of directly writing breakpoint instructions.
6617 * sparcdep.c on remote_debugging,there is no need
6618 to remove signle step breakpoint instructions.
6619 * main.c added "-epoch" flag and "int epoch_interface" to main.c
6621 * printcmd.c - epoch interface sends lisp expressions to open up
6622 epoch windows on inspection.
6623 * valprint.c - added arrayprint, and addressprint and made adding
6624 format controls easier
6625 * wait.h added a couple of undef's because we were getting
6626 complaints about WSTOPSIG and WTERMSIG begin redefined.

6651 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
6653 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
6654 should print ANSI qualifiers (such as `const' and `volatile').
6655 All callers changed to call with ANSI == 1, except from
6656 `check_method_stub', which uses old-style syntax.
6658 * symseg.h (struct fn_field): Remove unneccessary `args' field.
6659 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
6661 * values.c (check_stub_method): New function.

6680 * blockframe.c (blockvector_for_pc): New function.
6681 * blockframe.c (block_for_pc): Changed to call
6682 `blockvector_for_pc' and get the block itself.
6684 * stack.c (catch_info): New function. Prints info about

6687 `print_frame_local_vars'.
6688 * stack.c (print_block_frame_labels): Prints out labels that are
6689 defined in this frame. These labels are exceptions that can be

6694 Thu May 3 22:10:00 1990 Michael Tiemann (tiemann at teacake)
6696 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
6697 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
6698 when printing the type.
6700 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)

6715 * breakpoint.c (watch_command, bpstat_stop_status): Deal with
6716 exp_valid_block field correctly.
6718 * infrun.c (wait_for_inferior): When checking "don't even think
6719 about breakpoints" if stop_signal == SIGTRAP && trap_expected,
6720 also check step_resume_breakpoint.
6721 Insert breakpoints and continue (not step) if
6722 step_resume_break_address != NULL, even if another_trap.
6723 If trap_expected and we enter sigtramp, then set up a
6725 If trap_expected is set when we hit the step_resume_break,
6727 When calling resume and trap_expected says tell resume to step
6728 (2 places), also check step_resume_break_address.
