3 * mipsread.c (parse_partial_symbols): patch to keep DEC C
4 compiler from making gdb bomb out. Thanks to Ed Santiago!
6 Thu Nov 14 19:27:30 1991 Fred Fish (fnf at cygnus.com)
8 * symfile.c: Add function compact_misc_function_vector() to
9 remove duplicate misc function vector entries. See comments
10 in source for why this is necessary/desirable.
12 * dwarfread.c: Add misc function type parameter to internal
13 record_misc_function(). Remove calls to init_misc_bunches()
14 and condense_misc_bunches(), these are now done in elfread.c.
16 * elfread.c: Add support for reading bfd canonical symbol tables
17 and generating misc function vector entries for global and
18 absolute symbols. Do calls to init_misc_bunches() and
19 condense_misc_bunches() where they will enclose all calls to
20 record_misc_function(), including those in dwarfread.c.
22 Thu Nov 14 17:02:11 1991 Roland H. Pesch (pesch at cygnus.com)
24 * doc/Makefile.in: new targets gdb.me, gdb.ms, gdb.mm

32 that shuffle parameters into other regs.
33 * symtab.c (decode_line_1): Fix bug introduced in Per's change
36 Wed Nov 13 19:51:11 1991 Steve Chamberlain (sac at cygnus.com)
38 * Makefile.in, xconfig/delta88 made it install a sysV manual page;
39 gdb.z into the right place.

43 Motorola 88000 port without tears, I mean without tdescs.
45 * m88k-tdep.c: Blow away all tdesc stuff.
46 Provide functions for all the frame-related macros in
47 tm-delta88.h. Adopt i960-style EXTRA_FRAME_INFO.
48 (examine_prologue, frame_find_saved_regs, skip_prologue): borrow
49 from i960-tdep.c and adapt to the function prologues on the 88k.
50 (read_next_frame_reg): Borrow from mips-tdep.c.
51 FIXME: frame_locals_address should go away.
53 * tm-delta88.h: Dump all the tdesc stuff.
54 Macros for all frame-related stuff call fns of same name.
55 Remove duplicated definitions. FP_REGNUM becomes same as
58 * xm-88k.h: Eliminate lots of library dependencies, now handled
59 in libiberty. Eliminate KDB nonsupport.
61 * doc/gdbint.texinfo: Add rudiments on frames. FIXME, add more.
64 * stack.c (frame_info): Mark frameless functions.
65 Print locals address (FIXME, remove if same).
66 * blockframe.c: Comment changes, FIXME after.
67 * coffread.c: Even without TDESC, need to zap "@" symbols.
68 Don't register for wierd format names; change the names in BFD.
70 * alloca.c, language.c, tdesc.c: Lint.
71 * tdesc.c, tdesc-lib: FIXME: remove these.
73 Tue Nov 12 19:30:22 1991 John Gilmore (gnu at cygnus.com)
75 * Makefile.in: Add tdesc library support. Fixups to lint,
78 Tue Nov 12 13:43:26 1991 Per Bothner (bothner at cygnus.com)
80 * symtab.c (decode_line_1): Remove spurious call to operator_chars.
82 Allow setting breakpoints on C++ destructors.
83 * valops.c (destructor_name_p): Don't check TYPE_HAS_DESTRUCTOR,
84 since it lies. Rely on callers to catch missing destructors.
85 * symtab.c (decode_line_1): For example (see above), here.
86 * buildsym.c, symtab.h: Remove TYPE_FLAGS_HAS{CON,DE}STRUCTOR
87 flags since they are no longer used.
89 Fixes to support C++ methods with functional parameters.
90 * c-exp.y (func_mod rule): Allow (and ignore) list of parameter
91 types in a function type.
92 * eval.c (parse_and_eval_type), value.h: New function,
93 parse_and_eval_type, is based on old code from check_stub_method.
94 But don't actually evaluate the cast, since that calls
95 value_cast(), whcih may fail. Just extract the type
96 from the parsed expression.
97 * values.c (check_stub_method): While looping through the
98 arguments, adjust depth *after* parameter has been handled.
99 Replace call and setup of parse_and_eval with new function
102 Tue Nov 12 09:40:07 1991 Fred Fish (fnf at cygnus.com)
104 * utils.c, rem-multi.shar: Remove fixed arg count version of
107 * altos-xdep.c, arm-xdep.c, coffread.c, command.c, convex-xdep.c,
108 core.c, dwarfread.c, gould-xdep.c, infcmd.c, language.c,
109 m88k-xdep.c, main.c, printcmd.c, pyr-xdep.c, source.c,
110 sun386-xdep.c, symm-xdep.c, umax-xdep.c, values.c, xcoffread.c:
111 Change all instances of use of fixed args concat() to variable
112 args concat() now located in libiberty.
114 Tue Nov 12 07:23:46 1991 John Gilmore (gnu at cygnus.com)
116 * Makefile.in: Add xcoffread.c, xcoffexec.c.
117 * xcoffread.c: New file for handling AIX mangled-coff files.
118 * xconfig/rs6000, tconfig/rs6000: New files.
119 * buildsym.c: Add hooks for xcoffread.c.
120 * rs6000-pinsn.c, rs6000-tdep.c, rs6000-xdep.c, tm-rs6000.h,
121 xm-rs6000.h, rs6k-opcode.def, rs6k-opcode.h: New files.
122 * xcoffexec.c: New file for handling AIX shared libraries.
124 Mon Nov 11 19:14:31 1991 Fred Fish (fnf at cygnus.com)
126 * core.c: Minor rewording of message to user containing name of
127 (and possibly arguments to) the program that generated a core
130 * elfread.c: Remove the register_addr() stub now that it is no
133 * procfs.c: Move misplaced #endif for ATTACH_DETACH. Add new
134 fetch_core_registers() function for core file support.
136 Sat Nov 9 13:37:57 1991 Fred Fish (fnf at cygnus.com)
138 * dwarfread.c (dwarf_psymtab_to_symtab): Remove leftover call
139 to do_cleanups() which resulted from a previous change.
141 * elfread.c: Re-enable compilation of register_addr() stub
142 whenever it is not supplied by coredep.c
144 Sat Nov 9 00:40:32 1991 John Gilmore (gnu at cygnus.com)
146 Add tracking of object files (that contain symbols) to gdb.
147 This includes a "struct objfile" that owns symtabs and psymtabs
148 that were read in from that binary file.
150 * symfile.h: Add struct objfile. Add pointer to the objfile
151 into the struct sym_fns.
152 Replace global `symfile' and `symfile_mtime' with
153 `symfile_objfile'. Add global object_files chain.
155 * symfile.c: Move param.h above symtab.h.
156 (sort_misc_function_vector): Add.
157 (syms_from_objfile): Was syms_from_bfd.
158 (symfile_open): Now returns objfile.
159 (allocate_objfile): New.
160 (free_objfile): New, replacing free_all_.*symtabs.
161 (symfile_init): Takes objfile arg, puts it in sym_fns result.

163 (allocate_symtab): Takes objfile as new parameter, chains them.
164 Handle INIT_EXTRA_SYMTAB_INFO.

167 * dbxread.c: Make more errors into complaints.
168 (push_subfile, pop_subfile): Move to buildsym.c.
169 (dbx_symfile_read, dbx_symfile_init, fill_symbuf, read_dbx_symtab,
170 start_psymtab, psymtab_to_symtab_1, read_ofile_symtab,
171 dbx_psymtab_to_symtab, ): Use bfd ops, don't use file descriptor.
172 Pass objfile. Change callers.
173 (fill_symbuf, SWAP_SYMBOL): Take bfd as arg.
174 (read_dbx_symtab): Just wipe out new symbols, not all, on error.
175 (end_psymtab): Blow away psymtab if empty.

180 * buildsym.c (end_symtab): Pass objfile.
181 (dbx_lookup_type): Handle null typevector.
182 (dbx_alloc_type): Check file number, not sym number, for -1.
183 (find_symbol_in_list): Add for xcoffread.
184 (start_symtab): Default typevector is empty. Keep reusing same
186 (end_symtab): Take objfile argument and pass it to
187 allocate_symtab. Don't make a symtab if no blocks or symbols.
188 Handle empty typevector.
189 (push_context): New function for context stack nesting.
190 (read_type): Mark FIXME where we need to reintroduce type smashing.
192 * buildsym.h (pop_context): Macro, paired with push_context.
193 (subfile_stack): Move here from dbxread.c.
195 * coffread.c (end_symtab, read_coff_symtab): Take and use objfile arg.
196 (read_coff_symtab): Cleanup by freeing objfile, not all symtabs.
198 * mipsread.c (read_mips_symtab, parse_partial_symbols, parse_fdr,
199 new_psymtab, new_symtab): Take and use objfile arg.
201 * dwarfread.c (scan_compilation_units, start_psymtab,
202 process_dies, end_symtab, dwarf_build_psymtabs,
203 read_lexical_block_scope, read_func_scope, read_file_scope): Take
204 and use objfile argument.
205 (psymtab_to_symtab_1, read_ofile_symtab): Don't take or use file
206 descriptor. Use BFD internal functions instead.
207 (end_symtab): Call global allocate_symtab.
209 * elfread.c, target.c: Minor changes to accommodate objfiles.
210 * symtab.h: partial_symbol_table has no symfile_name member now.
211 (fn_fieldlists voffset): avoid non-int bitfield.
212 (struct symtab): Add objfile * and objfile_chain * of symtabs.
213 (struct partial_symtab): Add objfile * and objfile_chain * of
214 psymtabs. Remove symfile_name.
216 * symmisc.c: Lose free_all_symtabs, free_all_psymtabs.
217 (printsyms_command): Rename from print_symtabs. Add selective
218 listing if 2nd argument given. Print objfile info.
219 (printpsyms_command): Rename from print_partial_symtabs. Ditto all.
220 (printobjfiles_command): New; prints objfiles lists, and checks
221 for consistency of symtab, psymtab, and objfile lists.
223 * symfile.h, symfile.c, symtab.h: Lint
225 Fri Nov 8 23:38:48 1991 John Gilmore (gnu at cygnus.com)

228 * defs.h (warning_setup, warning): Declare.
229 * expprint.c (print_subexp, UNOP_MEMVAL case): Lint.
230 * inflow.c (new_tty): Use USE_O_NOCTTY #define.
231 * language.c, printcmd.c (print_scalar_formatted), signame.c,
234 Thu Nov 7 18:26:15 1991 Steve Chamberlain (sac at rtl.cygnus.com)
236 * Makefile.in: link with libiberty after libreadline, since
237 readline might want something in libiberty.
238 * m88k-xdep.c: Fixed the register offsets in the ptrace_user
239 struct for BCS 88k machines.
240 * xm-m88k.h: don't define USIZE if already defined.
241 * configure.in: Added delta88 target.
243 Thu Nov 7 04:51:19 1991 John Gilmore (gnu at cygnus.com)
245 * am29k-pinsn.c, am29k-opcode.h: Fix decoding of mtacc, dmac, fmac.
247 * tm-*.h: Remove READ_DBX_FORMAT, COFF_FORMAT, and
248 READ_MIPS_FORMAT, which have been unused since BFD. Still
249 remaining is COFF_NO_LONG_FILE_NAMES.
250 * tm-sun3.h, tm-altos.h: Remove detritus accidentally left from
251 function calling code moved to m68k-tdep.c.
253 Wed Nov 6 17:21:59 1991 John Gilmore (gnu at cygnus.com)
255 * coffread.c: Eliminate c_nsyms in favor of c_naux.
256 Complain if no auxents on .bf and .ef FCN symbols, and assume
257 lots of line numbers.
258 (init_linenos, enter_linenos): Use a sentinel at the end of the
259 read-in linenos, to make for a fast, safe loop-end test.
261 Wed Nov 6 02:54:08 1991 Steve Chamberlain (sac at cygnus.com)
263 * coffread.c (read_coff_symtab): coffread used to rely on the
264 x_sym.x_misc.x_lnsz.x_lnno field giving the # of linnos in a
265 function. Two of the formats I'm using (29k and 88k) don't seem to
266 set it. Ths patch to fcn_last_line and (enter_linenos) is an
267 attempt to use the actual size of the linno table in the file to set
268 the number of linenos to process.
270 Tue Nov 5 22:47:46 1991 Steve Chamberlain (sac at cygnus.com)
272 * Makefile.in: put a - infront of the mv y.tab.c c-exp.tab.c and
273 mv y.tab.c m2-exp.tab.c, so that if bison is used, and the files
274 are created in place, so the mv fails, then the make continues.
276 Tue Nov 5 16:47:47 1991 Per Bothner (bothner at cygnus.com)
278 Add C++ as a separate language.
279 * defs.h (enum language): Add language_cplus.
280 * dwarfread.c (end_symtab): Support language_cplus.
281 * c-exp.y: Add new struct language_defn cplus_language_defn.
282 Don't set c to be the default language (see main.c).
283 * c-exp.y (yylex): Only look for field of this if
284 language is C++. (First difference from C!)
285 * language.c: Add case branches for C++ (currently, all
286 the same as C). Also, add c++ to "usage" note for "set lang".
287 * valprint.c (typedef_print). Add case branches for C++.
288 * main.c (main): New way to set initial language: Look at
289 file extension of psymtab containing main(). (Same as we
290 do for symtabs, but avoid loading the symtab yet.)
291 * symtab.c: New routine find_main_psymtab(), used by main()
292 to set initial language.
293 * symfile.c (allocate_symtab): Move code for mapping file
294 extensions-> languages to new deduce_language_from_filename().
296 Fix a C++ problem when looking for methods in super-classes.
297 There was confusion between base and derived types.
298 * valops.c (value_fn_field): Change function interface.
299 * values.c: Use new value_fn_field interface.
301 Mon Nov 4 10:49:33 1991 Per Bothner (bothner at cygnus.com)
303 * infrun.c: Fixed typo in comment.
304 * utils.c: All the v*fprintf emulation is now in libiberty,
305 so we can get rid of some junk.
306 * xm-sun3os4.h, xm-sun4os4.h, xconfig/decstation, xconfig/i386sco,
307 xconfig/sun3os4, xconfig/sun4os4: Don`t need HAVE_STRSTR any more.
308 * m68k-pinsn.c (print_insn_arg): Support BB/BW/BL
309 type operands, as used by branch instructions.
310 * gmalloc.c: Fix prototype of memcpy.
311 * elfread.c: Comment out register_addr, since it conflicts
312 with the one in coredep.c.
313 * buildsym.h: Remove extern declarations of two functions
314 that are really static in buildsym.c.
315 * tm-mips.h: Add symbolic names for more registers.
316 * mips-xdep.c (store_inferior_registers): Use new register names.
317 * xm-mips.h: Simplify REGISTER_U_ADDR, since it is now
318 only used for core files, not ptrace. Therefore,
319 the KERNEL_U_ADDR hack is no longer needed.
320 The mapping to ptrace number is now in in mips-xdep.c.
321 * mips-xdep.c: Define REGISTER_PTRACE_ADDR (using the
322 mapping from the old REGISTER_U_ADDR), and use it
323 in {fetch,store}_inferior_registers.
324 * mipsread.c: Rename #include ecoff.h to new name coff-mips.h.
325 * mips-tdep.c (mips_push_dummy_frame, mips_pop_frame):
326 Save/restore FP regs correctly (?).
327 * dbxread.c: Remove duplicate define_symbol and type_synonym_name
328 (these had been previously moved to buildsym.c).
329 Hence, define_symbol becomes extern instead of static.
330 * buildsym.c (read_struct_type): Comment out bogus handling
331 of C++ operator methods. Minor hacking of reading of class
332 contexts. Make define_symbol non-static, so dbxread.c can call it.
334 Fri Nov 1 11:05:47 1991 John Gilmore (gnu at cygnus.com)
336 * mipsread.c (read_mips_symtab, read_the_mips_symtab): Use real
337 filename with error messages.
338 * stack.c (frame_select_command): Rename to select_frame_command
339 to avoid "fr" and "fra" having nonunique completions.
340 * symfile.c (sort_symtab_syms): Ignore sort of zero symtab *.
341 (symfile_init): Print file format name when unable to handle it.
342 (free_named_symtabs): Use BLOCKVECTOR rather than obsolete BLOCKLIST.
343 * symmisc.c (free_symtab): Only free linetable if nonzero.
344 * symtab.h: Remove obsolete BLOCKLIST macros.
346 Thu Oct 31 18:12:43 1991 Stu Grossman (grossman at cygnus.com)
348 * infrun.c (wait_for_inferior): another stepi/nexti fix. Ensure
349 that stop_step is 1 at bottom of main loop. I don't know why this
350 needs to be done, but it helps me sleep better at night.
352 Sun Oct 27 18:18:39 1991 Stu Grossman (grossman at cygnus.com)
354 * main.c (initialize_history): Read history after reading all
357 Sun Oct 27 14:09:25 1991 John Gilmore (gnu at cygnus.com)
359 * buildsym.c: Break out initial malloc sizes.
360 (record_line): Record directly in a subfile. Alloc on demand.
361 (compare_line_numbers): Add from xcoffread.c.
362 (end_symtab): New params say whether to sort pendings and
363 linetable. Patch block stabs if defined. Shrink linetable before
364 allocating the symtab.
365 * buildsym.h: Delete line_vector* and prev_line_number. Add
366 global_stabs and file_stabs for xcoffread.
367 * dbxread.c (start_subfile): Move to buildsym. Change above calls.
368 * symtab.h: LINETABLE(symtab) can now be null. Zap LINELIST.
369 * symmisc.c, symtab.c: Cope with null LINETABLEs.
371 * blockframe.c: Pass fromleaf to INIT_EXTRA_FRAME_INFO.
372 * tm-29k.h, tm-88k.h, tm-i960.h, tm-irix3.h, tm-mips.h, tm-pyr.h,
373 tm-sparc.h: Accept fromleaf parameter.
374 * c-exp.y (yyerror): Pass error message if given.
375 * configure.in: Add rs6000 host and target.
376 * inflow.c (new_tty): O_NOCTTY kludge for RS/6000.
377 * symfile.h (entry_point): Add.
379 Sat Oct 26 00:16:32 1991 John Gilmore (gnu at cygus.com)
381 * buildsym.c: New file. Breaks out symbol-table-building routines
382 from dbxread.c, so they can be shared with xcoffread.c.
383 * buildsym.h: New file. Declarations for buildsym.c users.
384 * dbxread.c: Remove large chunks into buildsym.c.
385 * Makefile.in: Add buildsym.c and buildsym.h.
387 * symfile.c (syms_from_bfd): New routine.
388 (add_symbol_file): Call it to do the real work.
389 (syms_from_bfd): Initialize entry_point before calling symfile_init.
390 * symtab.h, symfile.c, coffread.c, mipsread.c, dwarfread.c:
391 Avoid declaring or setting entry_point (symfile.h & symfile.c cope).
393 Fri Oct 25 10:58:16 1991 Mark Eichin (eichin at cygnus.com)
395 * cplus-dem.c (cplus-demangle): added support for templates, static
396 data, and the new (correct) mangling for destructors.
398 * dwarfread.c: (dwarfwarn): created a varargs version of
399 dwarfwarn, for non __STDC__ compilers.
401 * c-exp.y: (yylex): added match for "template" token.
402 (typebase): added TEMPLATE name '<' type '>' clause, for explicit
403 specification of template types.
405 * symtab.c: (lookup_template_type): new function for finding
406 templates in symbol table.
407 (type_name_no_tag): changed to explicitly check for s/u/e at the
408 beginning of the symbol - if it is a template, none of these will
409 be there (but the name will still contain spaces.)
411 Fri Oct 25 18:59:32 1991 Per Bothner (bothner at cygnus.com)
413 Various fixes to improve g++ debugging.
414 * symtab.h: Add is_const and is_volatile flags for each method.
415 These are bit fields - take their space from voffset,
416 which shrinks to 30 bits. Since voffset is now a bitfield,
417 make it unsigned for portability. This changes its interpretation
418 slightly: Static methods now have voffset 1 instead of -1,
419 and virtual offsets start at 2, not 1.
420 * symtab.c: Renamed gdb_mangle_typename to gdb_mangle_name,
421 since it now returns an entire magled method name, not just
422 the type part. This avoids some duplication.
423 It also allows us to correctly mangle const and volatile
424 methods (using the new is_const and is_volatile bit fields
426 * valprint.c (type_print_base), values.c (check_stub_method):
427 Simplify by using new gdb_mangle_name.
428 * values.c (value_headof): Fix to correctly handle single
429 inheritance (actually two fixes, either of which suffices).
430 * dbxread.c (read_struct_type): Handle const and volatile
432 * dbxread.c (read_struct_type): Yet one more place where
433 we must handle '\\' continuations.
434 * valprint.c (vtbl_ptr_name): Add final '\0'.
436 Fri Oct 25 16:06:38 1991 Stu Grossman (grossman at cygnus.com)
438 * tm-sparc.h, tm-68k.h (EXTRACT_RETURN_VALUE): fix output of
439 short return values for sparc and 68k. Patch from Paul Eggert.
441 * coffread.c, coredep.c, i386-xdep.c: install patches for
442 SysV/386 3.2 from Mauro DePalma.
444 Fri Oct 25 02:02:13 1991 John Gilmore (gnu at cygnus.com)
446 * core.c (core_file_info), exec.c (exec_file_info): Print file
447 type. Use printf_filtered.
449 * valops.c (value_fetch_lazy): Avoid 0-length fetches.
451 Thu Oct 24 23:06:40 1991 Fred Fish (fnf at cygnus.com)
453 * dwarfread.c: Add casts to remove compiler warnings.
455 * tm-3b1.h, tm-68k.h, tm-altos.h, tm-amix.h, tm-hp300bsd.h,
456 tm-hp300hpux.h, tm-isi.h, tm-news.h, tm-pn.h, tm-sun2.h,
457 tm-sun3.h: Remove locally duplicated code for calling functions
458 in the inferior. The only differences were in the specific trap
459 vectors used and whether or not an fpu was present. These are
460 now handled by appropriate definitions of BPT_VECTOR and
461 HAVE_68881 respectively. Other minor obvious cleanups.
463 * valops.c: Correct a minor misspelling.
465 * utils.c: Remove local BSD/USG hacks that are now in libiberty.
467 * dwarfread.c: Remove prototype for dwarfwarn. Does not work
470 Thu Oct 24 09:33:44 1991 John Gilmore (gnu at cygnus.com)
472 * stack.c (frame_command): Always print. Use new
473 frame_select_command to select a frame without printing.
475 * dwarfread.c: Use <varargs.h>, since <stdarg.h> is not portable.
477 Thu Oct 24 01:32:51 1991 Fred Fish (fnf at cygnus.com)
479 * dwarfread.c: New file for DWARF debugging format support.
481 * elfread.c: New file for ELF object file format support.
483 * procfs.c: New file for SVR4 /proc (process file system) support.
485 * tm-amix.h, xm-amix.h, tconfig/amix, xconfig/amix: New files for
488 * xm-svr4.h, tm-svr4.h: New files for SVR4 support.
490 * xm-m68k.h: New file for host machines with m68k cpu.
492 * Makefile.in: Add elfread.c and dwarfread.c to SFILES_MAINDIR.
493 Add elfread.o and dwarfread.o to OBS.
495 * symfile.h: Add "elf" to list of supported formats in comment.
497 * c-exp.y, defs.h, symtab.h, valprint.c: Add three new builtin
498 types to gdb, builtin_type_long_double, builtin_type_complex, and
499 builtin_type_double_complex. Add and use new TARGET_SHORT_BIT,
500 TARGET_INT_BIT, TARGET_LONG_BIT, TARGET_FLOAT_BIT,
501 TARGET_DOUBLE_BIT, TARGET_LONG_DOUBLE_BIT, TARGET_COMPLEX_BIT, and
502 TARGET_DOUBLE_COMPLEX_BIT, as the sizes in bits of the indicated
503 types on the target machine (ala the existing TARGET_LONG_LONG_BIT).
505 * infrun.c: When using SVR4 /proc interface instead of ptrace(),
506 call proc_set_exec_trap() to setup child to stop at first instruction.
508 * inftarg.c: When using SVR4 /proc interface, call proc_wait()
511 * m68k-tdep.c: Add new routines supply_gregset(), fill_gregset(),
512 supply_fpregset(), and fill_fpregset(), which are machine
513 dependent support routines for SVR4 /proc interface.
515 * utils.c: Add warning_setup() and warning(). Warning() behaves
516 the same as error() except that it returns normally rather than
517 jumping back to command level. Modules that don't want to call
518 warning() for some reason, but want to produce their own warnings,
519 can call warning_setup() to ensure compatibility with the way
520 warning() and error() deal with the terminal.
522 * symtab.c: Make internal errors produce more useful messages.
524 * tm-68k.h: Move code that is duplicated in almost every single
525 m68k based machine's configuration files to this common file.
526 Duplications in the configuration files still need to be removed
529 * infrun.c (child_create_inferior): System V versions must call
530 setpgrp() with no arguments, to comply with prototyping typically
533 * munch: Add support for SVR4 style nm output.
535 * dbxread.c, mipsread.c symmisc.c, symtab.c: Remove the object
536 file specific fields from the partial symbol table structure and
537 replace them with a pointer to private data for each different
538 flavor of object file reader to initialize appropriately.
540 Wed Oct 23 09:38:20 1991 John Gilmore (gnu at cygnus.com)
542 * xconfig/sun[34]os4: Add note about strstr botch on sunos4.0.3c
545 * mipsread.c (fixup_undef_type): New function. If a struct /
546 union / enum is defined in a header file but nowhere else used,
547 (by typedefing, pointer referencing or declaration) the mipsread code
548 builds the complete tree for the structure but leaves its code as
549 TYPE_CODE_UNDEF as it doesn't know what kind of aggregate it is.
550 Guess its type based on the details of the members.
552 Tue Oct 22 18:04:32 1991 Stu Grossman (grossman at cygnus.com)
554 * infrun.c (wait_for_inferior): Check return value from
557 Mon Oct 21 17:47:03 1991 Stu Grossman (grossman at cygnus.com)
559 * infrun.c (wait_for_inferior): fix stepi/nexti that was broken
560 by my last edit to this routine.
562 Mon Oct 21 14:27:43 1991 John Gilmore (gnu at cygnus.com)
564 * tm-sun3.h (FIX_CALL_DUMMY): problem with cross debugging.
565 FIX_CALL_DUMMY does unaligned accesses and/or forgets to byte swap
566 the values before putting them into the dummy code. (From Peter
569 Mon Oct 21 10:04:39 1991 Steve Chamberlain (steve at rtl.cygnus.com)
571 * configure.in: added ebmon target.

578 * README, TODO, WHATS.NEW: Update.
580 * core.c (core_open): Improve error message for bad file.
581 Pass .reg virtual memory address to fetch_core_registers to help
582 it find the registers in the core-file header.
583 * coredep.c (fetch_core_registers): Take new argument, use it,
584 and pass it to register_addr to locate the block of registers.
585 * xm-mips.h: Update KERNEL_U_ADDR for new scheme. Cleanup a bit.
587 * dbxread.c (read_dbx_symtab, process_one_symbol): Handle
588 Sequent N_FN_SEQ like everybody else's N_FN.
590 * main.c: Circumvent SCO cc bug with #if !!defined(USG).
591 * tm-i386v.h: #endif guck.
592 * xconfig/i386*: Remove -Dgetpagesize()=4096 kludge.
593 * xconfig/i386sco: Add HAVE_STRSTR to avoid ANSI bdeath.
594 * xconfig/tahoe: Add REGEX, which seems to be missing.
596 * coredep.c: Add <sys/types.h> for SCOnix.
597 * dbxread.c (read_dbx_symntab): Avoid coredump on malformed file.
598 * printcmd.c (print_formatted): Flush output before disassembly.
600 Tue Oct 15 20:12:32 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
602 * doc/refcard.tex (sec "Working Files"): consistent metavars and
603 other improvements, due to comments by François Pinard
604 (pinard@iro.umontreal.ca)
606 * doc/gdb.texinfo (appendix "Installing GDB"): changes in
607 configure, and improvenets related to Pinard's refcard comments
609 Tue Oct 15 08:45:12 1991 John Gilmore (gnu at cygnus.com)
611 Changes from Fred Fish:
612 * tm-68k.h (FPI_REGNUM): Add.

626 * i387-tdep.c (double_to_i387): Fix typo for double_to_ieee_extended.
627 * utils.c (_initialize_utils): If !ISATTY, don't paginate.
628 * configure.in, tconfig/decstation, xconfig/decstation: Rename
629 dec3100 to decstation.
631 Mon Oct 14 13:37:50 1991 Roland H. Pesch (pesch at cygnus.com)
633 * doc/gdb.texinfo: Catch up to changes recorded here in ChangeLog
634 (nodes Continuing and Stepping; Memory; Targets) clarifications
637 Fri Oct 11 23:27:06 1991 John Gilmore (gnu at cygnus.com)
639 * tm-{irix3,mips,nindy960,pn,symmetry,vx960}.h: Move
640 REGISTER_U_ADDR to corresponding xm- file. Sugg. by Peter Schauer.
642 * symmisc.c (print_partial_symtabs): Add printpsyms debug cmd.

645 generic routines for calling inferior functions.
647 * blockframe.c (inside_main_scope, inside_entry_scope): New.
649 * copying.awk: Filter formfeeds out of copying & warrantee.

656 core-file reading code.
657 * core.c (get_core_registers): Avoid coredump if no .reg section.
659 Wed Oct 9 17:03:34 1991 John Gilmore (gnu at cygnus.com)
661 * mipsread.c, coffread.c: initialise TYPE_VPTR_FIELDNO to -1.
662 This avoids coredumps under `set print object on' in value_headof
663 (called erroneously by value_from_vtable_info) for `p &struct'
664 or `p *struct'. From Peter Schauer.
666 Mon Oct 7 00:06:52 1991 John Gilmore (gnu at cygnus.com)
668 * Makefile.in: Roll version to 4.1.2.
669 * dbxread.c: Use aout64.h, not a.out.gnu.h. Get external symbol entry
670 size from BFD (but, FIXME, we don't yet read external nlists's and
671 convert them to internal nlists's before handling them -- we still
672 assume they have the same size and alignment.) Use SET_NAMESTRING
674 * exec.c (exec_file_command): Move dead coff-encapsulation code
676 * m88k-tdep.c, m88k-xdep.c: Remove encap test and #inc <a.out.h>.
678 Fri Oct 4 22:30:06 1991 John Gilmore (gnu at cygnus.com)
680 * configure.in, tm-i386v.h, xm-i386v.h: Intel 386 Mach host port.
681 * xm-i386mach.h, mach386-xdep.c, xconfig/i386mach: New files.
683 Fri Oct 4 17:04:31 1991 Per Bothner (bothner at cygnus.com)
685 More patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
686 * mips-xdep.c (store_inferior_registers): Don't try to
687 write the (pseudo) FP.
688 * mipsread.c (parse_partial_symbols): Improved algorithm for
689 setting pst->texthigh.
691 Fri Oct 4 16:47:32 1991 Roland H. Pesch (pesch at cygnus.com)
693 * doc/Makefile: make TEXINPUTS include . everywhere
695 Fri Oct 4 00:35:56 1991 John Gilmore (gnu at cygnus.com)
697 * coffread.c, dbxread.c, symfile.c, symmisc.c, symtab.h: Remove
698 vestiges of typevectors, which were for symsegs and are no longer
699 used. (From a question by Eliot Dresselhaus
700 <dresselh@RFT30.nas.nasa.gov>).
702 Thu Oct 3 09:33:26 1991 John Gilmore (gnu at cygnus.com)
704 * dbxread.c, coffread.c: static-ize functions that were
705 gratuitiously external. (From Fred Fish.)
707 * c-exp.y: sym->class to SYMBOL_CLASS (sym).
709 * dbxread.c (dbx_lookup_type): Keep doubling size of typevector
710 until it is large enough.
712 * dbxread.c (read_type): Handle error case slightly better.
713 Make complaint message not C++-specific.
715 Wed Oct 2 17:21:07 1991 Stu Grossman (grossman at cygnus.com)
717 * infrun.c (wait_for_inferior): Fix step/next so that you only
718 stop at the beginning of a new line. This fixes various problems
719 with for loops, nested if-else's and switch statements.
721 Tue Oct 1 06:33:55 1991 John Gilmore (gnu at cygnus.com)
723 * symtab.c (lookup_symtab_1, lookup_symbol): "fatal" errors
724 between symtabs and psymtabs become ordinary error()s.
726 * dbxread.c (read_dbx_symtab): Relocate end_of_text_addr
727 properly, making "end pc" correct in shared lib psymtabs.
728 (From Guy Harris <guy@auspex.com>.)
730 Mon Sep 30 13:15:31 1991 John Gilmore (gnu at cygnus.com)
732 * dbxread.c: Enable, but soften, const_vol_complaint.
733 (read_dbx_symtab): N_STSYM and N_LCSYM define static vars.
734 Ditto Gould N_NBSTS and N_NBLCS. Also, all types in the psymtab
735 should be file-scope, not global.
736 (read_struct_type): Remove ancient multiple-inheritance warning.
737 (read_range_type): Check base type, complain & patch if undefined.
738 * stack.c (frame_info): Demangle the function name in `info stack'.
741 Sat Sep 28 10:02:33 1991 John Gilmore (gnu at cygnus.com)
743 * eval.c (evaluate_subexp_for_address): Don't use
744 TYPE_POINTER_TYPE directly (it might be zero if this type has
745 never had a pointer created before); use lookup_pointer_type.
746 * symtab.c (lookup_method_type): Arguments were swapped in all
747 callers, so fix it here. I'm amazed this worked at all!
749 Fri Sep 27 18:09:31 1991 John Gilmore (gnu at cygnus.com)
751 * c-exp.y, m2-exp.y: Define more yysymbols that happen to be
752 "bss" rather than "data" symbols, but which still conflict.
755 * coffread.c (coff_symfile_read): Use xmalloc, not malloc.
756 * core.c (core_files_info): Shorten output.
757 * exec.c (exec_files_info): Ditto.
758 (build_section_table): Ignore zero-length sections.
759 * language.c, printcmd.c: Lint.
760 * language.h (get_frame_language): Declare.
761 * saber.suppress: update.
762 * stack.c (find_relative_frame): Remove complex code that was

772 * nindy-tdep.c (nindy_frame_chain_valid): Use lookup_misc_func.
773 (Reported by Mark Peek <mark@imagen.com>.)
775 * solib.c (solib_map_sections): Relocate all sections, even
776 though only the text section's size is tracked. Mark ld_text
777 for eventual elimination as we generalize to N sections.
779 * infrun.c (wait_for_inferior): Don't check if the PC is in a
780 call_dummy if we were stopped by a random signal that is being
781 passed to the program. This produced wierd results when calling
782 functions in the inferior and signals (e.g. SIGALRM) were in use.
784 Tue Sep 24 18:05:30 1991 John Gilmore (gnu at cygnus.com)
786 * infrun.c (IN_SIGTRAMP): Not parenthesized properly.
787 Bugfix from Paul Eggert <eggert@twinsun.com>.
788 * tm-ultra3.h (IN_SIGTRAMP): Ditto.
789 * valprint.c (print_floating): Print 9 digits for IEEE floats.

798 Fri Sep 20 16:10:52 1991 John Gilmore (gnu at cygnus.com)
802 * Makefile.in (VERSION): Set to 4.1.
803 * language.c (set_language_command): Print useful help message,
804 and restore the language string after giving help.
805 * valprint.c (typedef_print): Print typedef in C or M2.
806 * symtab.c (list_symbols): Use it.
807 * main.c (main): Avoid any output before (gdb) prompt when -q.
808 * language.c (set_language_command): Handle errors by restoring
809 the language string to its current state (fix from A. Beers).
810 * doc/gdbint.texinfo: Roll in information from README. Rearrange
811 "how to install" and "how to print the doc" stuff so it drops
813 * configure.in: Rename rtpc CPU to romp to match config.sub.
814 * README, WHATS.NEW, TODO: Update for gdb-4.1.
816 Fri Sep 20 17:39:14 1991 Roland H. Pesch (pesch at cygnus.com)
818 * doc/gdb.texinfo: Updates from ChangeLog. set/show write,
819 autoloading shared libs, copyright etc on GDB startup, clean up $_
820 and $__ index refs, set/show listsize and related updates to list
821 cmd. New host/target configs.
823 Fri Sep 20 15:46:00 1991 Roland H. Pesch (pesch at cygnus.com)
825 * doc/Makefile: generate aux version-no file doc/gdbVN.m4
826 from main Makefile.in version definition
827 doc/gdb.texinfo: use version recorded in doc/gdbVN.m4 for current
829 Makefile.in (setup-to-dist): generate doc/gdbVN.m4
831 * doc/gdb.texinfo: merge new language-switching and lang-specific
834 Fri Sep 20 15:00:57 1991 Per Bothner (bothner at cygnus.com)
836 * mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
837 compilers (which may lack stddef.h).
839 Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com)
841 * dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and
842 N_WARNING are the same except for the N_EXT bit, so just use their
843 values alone, rather than OR-ing them with N_EXT.
845 Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com)
847 * mipsread.c (parse_lines): Deal with negative extended line
850 * c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid
851 global symbol conflicts.
853 Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
855 * .gdbinit: Move 'set complaints' to top, so it runs even in
856 case we aren't debugging GDB.
857 * language.c (_initialize_language): Fix type check and range
858 check documentation strings.
859 * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
860 language.c can use it. (Though language.c should really not be
861 handling warnings/errors the way it does, FIXME.)
862 * symtab.c (lookup_primitive_type): const lint.
864 Bugfix from Peter Schauer:
865 * source.c (lines_to_list): Make signed, to avoid comparison
866 going unsigned and complaining that -3 is too high for 21 lines.
867 * stack.c (lines_to_list): Ditto.
869 Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
871 * Makefile.in (HFILES): Add minimon.h.
872 (VERSION): Roll version number to 4.0.95.
873 (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
874 New rules for building distributions. Normal distribution
875 is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
876 one level up from here; it calls make-proto-gdb.dir to build a
877 directory `proto-gdb' which is an image of the release. The old
878 `gdb.tar.Z' rule still works too.
879 * config.sub, configure: Roll in latest from ..
881 Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
883 * doc/gdbint.texinfo: Reorder contents; reorganize new-host,
884 new-target, and new-config chapters; fix minor typos; come closer
885 to usual GNU markup conventions for @file @samp @code @var.
887 Thu Sep 19 17:04:12 1991 Per Bothner (bothner at cygnus.com)
889 Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
890 * mipsread.c (parse_partial_symbols): Enter the name of all
891 structs/unions... into the psymtab so we can access them if the
892 symtab is not read in.
893 * mips-tdep.c: Remove some unneeded #includes.
894 * xconfig/dec3100: Add HAVE_STRSTR.
896 Thu Sep 19 15:14:23 1991 John Gilmore (gnu at cygnus.com)

924 code for saving types of parameters with each function definition.
925 * dbxread.c (define_symbol, function and parameter cases): Ditto.
926 (read_dbx_symtab, case N_DEFD): Ignore.
927 (read_enum_type): Recognize FALSE/TRUE enum as Modula-2 BOOLEAN.

1005 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
1007 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
1008 entries are enclosed herein. Not all of these changes
1009 have been merged into the master GDB sources -- check the
1010 ChangeLog above here for the merge log.
1012 Mon Jun 3 17:05:45 EDT 1991
1014 m2-exp.y Created. Tested outside of GDB for a few days. Proper
1015 operators were added, C specific operators and tokens
1016 removed. yylex() revamped to some extent. Still things
1017 missing from the grammar, such as sets.
1018 Tested for two weeks in GDB v3.5.
1020 Tue Jun 11 17:23:48 EDT 1991
1022 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
1023 so they are built-in. Sort of a hack.
1025 Fri Jun 14 12:53:51 EDT 1991
1027 m2-exp.y Added range checking for numeric constants. Any numeric
1028 constant is assumed to be of builtin type INTEGER unless:
1029 (1) it is octal or hexadecimal, in which case it is a
1030 CARDINAL; (2) it is too big to fit into an INTEGER, in
1031 which case it is a CARDINAL.
1032 eval.c Added simple range checking for +, -, and * on integers.
1033 Doesn't work very well for *, since 6 * 1,000,000,000 =
1034 1,705,032,704, which fails the simple test of result >=
1035 first_operand, no matter in what order the operands are.
1037 Tue Jun 18 14:11:30 EDT 1991
1039 Broke the parser into parts, one containing the C grammar and the other
1040 containing code to be shared by all of the grammars.
1042 The following files no longer exist:
1047 The following files were added:
1049 c-exp.y (The C grammar)
1050 m2-exp.y (The Modula-2 grammar)
1051 parser-code.c (Code that is shared by the above grammar)
1055 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
1056 now necessary to use the Bison compiler compiler, since it
1057 will generate function/variable prefixes other than yy.
1059 Tue Jun 18 16:47:49 EDT 1991
1061 symtab.[ch] Added the external variable working_lang, than holds the
1062 value of the current working language.
1063 Added the ennumerated type language_mode, with the values
1064 language_auto and language_manual, the former meaning that
1065 GDB sets working_lang as needed, and the latter meaning
1066 that the value of working_lang is totally under user
1068 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
1069 REAL, BOOLEAN and CHAR. Also added the type codes
1070 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
1071 utils.c Added set_language_command and show_language_command to
1072 implement the GDB support commands "set language" and
1074 expression.h A number of identifiers were added to the type exp_opcode
1075 to facilitate Modula-2 builtin functions, integer
1076 division, and array indexing.
1078 Wed Jun 19 13:25:58 EDT 1991
1080 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
1081 if the language specified by working_lang requires the use
1082 of strict typing of expressions. Eventually, even this
1083 will be able to be changed by the user.
1084 Added the macro RANGE_CHECK, which evaluates to non-zero
1085 if the language specified by working_lang requires the
1086 checking of a value against the domain of its type.
1087 Eventually, even this will be able to be changed by the
1089 language.[ch] Predicates involving types (simple_type, ordered_type,
1090 same_type, integral_type, numeric_type, character_type,
1091 boolean_type, float_type) are added. These predicates are
1092 based on the current value of working_lang, and are handy
1095 Wed Jun 19 15:39:34 EDT 1991
1097 eval.c Added the function type_array_rank which computes the rank
1099 valarith.c Added the funtion value_bool, which when given a integer
1100 value.h value (ie. struct value *) as an argument, it returns a
1101 boolean value (ie. struct value *) true if that integer
1102 is non-zero, and a boolean value false otherwise.
1103 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
1104 will print out properly.
1106 Wed Jun 19 16:36:34 EDT 1991
1108 valops.c Added the function value_capitalize, which returns it
1109 value.h argument capitalized if its argument is a lowercase
1110 letter, or the argument unchanged if its argument is not a
1112 valarith.c Added the function range_check_p, which returns non-zero
1113 value.h if its value argument is between the integral bounds upper
1115 Added the function range_check_enum_p, which makes sure
1116 that its value argument is a valid member of the domain of
1118 Added the function range_check_range_p, which makes sure
1119 its value argument lies between the upper and lower bounds
1120 of its type argument, which must be a ranged type.
1121 Added the function check_array_index, which range and type
1122 checks an index of an array.
1123 Added the function value_multi_subscript, which computes
1124 array[idx1,idx2...idxN], given a value array and an array
1125 of values representing indicies.
1126 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
1127 unpack_long to work with TYPE_CODE_BOOL and
1130 Wed Jun 19 18:04:08 EDT 1991
1132 symtab.c Stored pervasive types in a structure and make
1133 lookup_pervasive_type() a lookup function that was based
1134 on working_lang. If lookup_pervasive_type() returned
1135 non-zero, then that value was returned (a fix, since
1136 before it simply wouldn't return the pervasive type.)
1137 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
1138 non-zero if the language specified by working_lang means
1139 "conversion" when it says "cast".
1140 valops.c Added the function value_real_cast(), which performs a
1141 value.h *cast*, not a *conversion*, which is what value_cast()
1142 does when it can. In particular,
1143 value_cast(<float_type>,4) = 4.0, while
1144 value_real_cast(<float_type>,4) = some mess.
1145 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
1146 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
1147 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
1148 and MIN on integral types. *NOTE*: These are currently
1149 hardcoded to work only if there are 8 bits per storage
1151 eval.c Made logical functions call value_bool to return a
1152 properly typed boolean value, based on working_lang.
1154 Thu Jun 20 11:55:27 EDT 1991
1156 valprint.c Types now print out in a Modula-2 fashion. This works for
1157 the cases when the type is printed out step-by-step, that
1158 is, it doesn't work when the name of a structured type
1159 (which includes the keyword "struct", etc.) is simply
1161 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
1162 since type specifications in C and Modula-2 are very
1163 different. The C printing of a type is very recursive,
1164 whereas in Modula-2 it is generally very simple. C has
1165 type prefixes and suffixes, which have no real analogue in
1166 Modula-2. Maybe type_print() should call a language
1167 specific type printer. This is also advantageous if we
1168 compile GDB to exclude some of the languages. We'll just
1169 leave those functions out.
1171 Thu Jun 20 16:57:10 EDT 1991
1173 dbxread.c When reading the complete symbol table in (via
1174 psymtab_to_symtab()), the number and types of function
1175 arguments are added to a function type. define_symbol()
1176 calls add_param_to_type() to accomplish this.
1177 Assumption: when we come across a function definition
1178 (N_FUN symbol with an 'f' or 'F' in the name), its
1179 arguments will appear before another function definition.
1180 When a function is found, a pointer to its type is placed
1181 in the global in_function_type. Changes that
1182 add_param_to_type() makes are to this global.
1183 valprint.c The type of a function now includes (for Modula-2) the
1184 types of its parameters.
1185 eval.c Type checking and a check for the proper number of
1186 arguments is now done for function calls. Not sure of the
1187 impact this has on C++ member function yet.
1189 Thu Jun 20 19:58:48 EDT 1991
1191 valprint.c Rewrote the type printer. Broke it into two language
1192 specific parts, adding the functions type_print_m2() and
1194 An unfortunate consequence is this: if you debugging a C
1195 program in Modula-2 mode (why?), info types does not work
1196 well with regular expressions, since the types are printed
1197 out in Modula-2 terminology, but stored in C terminology.
1198 language.[ch] Added the functions new_type_last(), type_keyword(), and
1199 type_sep() to aid in the printing of typedefs.
1200 symtab.c Made the printing of typedefs as language independent as
1201 possible through calls to new_type_last(), type_keyword(),
1204 Fri Jun 21 11:50:26 EDT 1991
1206 dbxread.c Check all incoming ennumerated types. If it looks like
1207 Modula-2's BOOLEAN type, then change the type_code of the
1208 type to TYPE_CODE_BOOL so we can process it as a boolean
1210 valprint.c Replaced some of the 0x%x with calls to sprintf and
1211 hexformat() in val_print().
1212 language.[ch] Added the function hex_to_string(), which converts its
1213 integral argument to a hexadecimal number (format is
1214 language based) and returns the result as a string.
1216 Mon Jun 24 12:25:07 EDT 1991
1218 valprint.c Some functions call type_print_1() directly, instead of
1219 value.h using type_print(), so they can specify where (column) to
1220 print things. Since type_print() takes care of language
1221 dependence, that needs to be called first. Added a
1222 parameter depth to type_print() (so it is now like
1223 type_print_1). Changed type_print to type_print_at, and
1224 made type_print a macro that passes a depth argument of
1226 symmisc.c Changed all calls to type_print_1 to calls to
1228 Makefile.dist Made it possible to build GDB for a specific set of
1229 depend languages. Do this by passing a definition for the macro
1230 LANGS to make. LANGS should be a string containing a
1231 space-separated list of language names (ie. LANGS="c m2").
1232 The default is to build all languages. Note that grammar
1233 files must follow the naming convention of <lang>-exp.y.
1234 gdb.lang This holds the current value of the LANGS macro. It is
1235 examined every time make is called, and is updated if
1237 eval.c Added #ifdef _LANG_<lang> to these files.
1238 expread.c Still need to add them to dbxread.c and coffread.c.
1246 Mon Jun 24 16:33:11 EDT 1991
1248 language.[ch] Added the functions hexformat_pre() and
1249 hex_to_string_pre(), which take a prefix argument to
1250 include in the format string. Thus, hexformat_pre("08") will
1251 return "0x08x" (if the working language is language_c).
1252 Made hexformat() and hex_to_string() calls to the above
1253 with "" as the prefix argument.
1255 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
1256 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
1257 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
1258 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
1259 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
1260 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
1261 valprint.c, vax-pinsn.c
1263 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
1264 calls to hexformat() and hex_to_string(). Format strings without
1265 the leading "0x" were ignored.
1267 depend Updated to take the above into account.
1270 Tue Jun 25 15:27:18 EDT 1991
1272 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
1273 and type_check_t to keep track of the current state of
1274 range and type checking.
1275 main.c Added the variables range_mode, range_check, type_mode,
1276 and type_check to record the current state of range and
1277 type checking. Added initialization code to main().
1278 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
1279 the above variables.
1282 Tue Jun 25 17:57:08 EDT 1991
1284 dbxread.c process_one_symbol() updates the variable (enum language)
1285 source_lang based on the extension of the filename
1286 contained in the N_SO sybmol that started this symtab.
1287 When end_symtab() is called, the value of source_lang is
1288 put into the language field.
1289 stack.c select_frame() sets working_lang (and possibly type_check
1290 and range_check) to the language field of the symtab
1291 associated with the frame that is selected if working_mode
1292 is language_auto. If working_mode is language_manual, a
1293 warning is printed and working_lang is not set.
1294 language.c Added the function set_type_range(), which sets the value of
1295 type_check and range_check (if their modes call for
1296 automatic setting) based on the current value of
1297 working_lang. A non-zero argument will cause the current
1298 settings to be output.
1301 Wed Jun 26 14:51:40 EDT 1991
1303 eval.c Added range checks on assignment.
1304 m2-exp.y Added the grammar for sets to the language. Currently,
1305 these do not do anything except print an error message.
1307 Wed Jun 26 17:01:04 EDT 1991
1309 m2-exp.y Added the ability for parse_number() to parse negative
1310 numbers. A global flag is set upon encountering a unary
1311 minus. This was done to make, for example, 1 parse as a
1312 CARDINAL, and not as an integer, per Wirth's examples in
1313 Programming in Modula-2 ed.4.
1314 valprint.c Added support for "set radix 2" by then setting
1315 output_format to 't'.
1316 eval.c Implemented range checking on subrange types. Added calls
1317 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
1318 Implemented MIN and MAX for ennumerated types. The
1319 minimum value of an ennumerated type is defined by Wirth
1320 as the first identifier, and the maximum as the last.
1321 m2-exp.y Made octal numbers ending with "B" be characters and those
1322 ending with "C" be numbers, per Wirth's book. (p. 34)
1324 Thu Jun 27 14:11:52 EDT 1991
1326 stack.c select_frame() now only sets working_lang, it does not
1327 notify the user. If working_mode is language_manual, then
1328 a warning is issued once.
1329 main.c At the end of each call to execute_command(), working_lang
1330 is checked against the local static (enum language)
1331 current. If they differ and working_mode is
1332 language_auto, the new settings of language, type and
1333 range checking are printed out.
1334 stack.c Modified frame_info() to include the language of the
1335 current frame in the output of "info frame".
1336 language.[ch] Added the function language_str() which returns the name
1337 of the current language.
1339 Fri Jun 28 15:33:14 EDT 1991
1341 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
1342 the language. INCL and DECL currently cause an error,
1343 since sets are not implemented yet. INC and DEC are
1344 implemented as PREINCREMENT/PREDECREMENT with one
1345 argument, and as ASSIGN_MODIFY with two arguments.
1346 eval.c Added type checking to the above cases.
1347 value.h Added not_lval_constant to the lval_type ennumerated type.
1348 not_lval_constant means that the value is a constant
1349 value; that is 3 or 'a' or TRUE, not as in a constant
1350 identifier. This is used to help coerce numbers such as 3
1351 to either signed or unsigned numbers.
1352 valops.c Added the function value_coerce_constants() which coerces
1353 constant integers as following: if one is a constant and
1354 the other is not, the constant's type is set to the type
1355 of the other argument. If both are constants and one is
1356 signed, the other is converted to a signed constant.
1358 Sat Jun 29 17:26:29 EDT 1991
1360 valarith.c Added a better range checker. It now checks range
1361 (successfully) on integral operations [+-] (signed and
1362 unsigned) for any C sized type. Still does not work well
1363 for multiplication.)
1364 int_in_size() returns an integer that is coerced to fit into
1365 specified number of bytes.
1367 Mon Jul 1 13:04:14 EDT 1991
1369 language.[ch] Added the function binop_result_type(), which returns the
1370 builtin (struct type *) type that would be the result of a
1371 binop on the two values V1 and V2.
1373 Wed Jul 3 19:22:53 EDT 1991
1375 source.c Extended source_info() to include the source language in
1376 the output from "info source".
1378 Fri Jul 5 13:48:52 EDT 1991
1380 utils.c Moved the support functions for the GDB set/show commands
1381 dealing with language into language.c.
1382 language.c Added the function language_info(), which displays info
1383 about the current working language, type and range check
1384 settings. Called via the GDB command "info language".
1385 Added an initialization routine _initialize_language(),
1386 that sets defaults for the language, type and range
1387 variables and sets up the new GDB commands.
1388 main.c Language setup moved to language.c.
1391 Mon Jul 8 10:10:22 EDT 1991
1393 valarith.c Debugged the range checker for arithmetic. Still does not
1394 work for multiplication very well.
1396 Mon Jul 8 12:40:37 EDT 1991
1398 language.[ch] Added the function value_true() which returns non-zero if
1399 its argument represents a boolean true value.
1400 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
1401 check the truth of an expression.
1403 Thu Jul 11 12:51:34 EDT 1991
1405 language.[ch] Added the predicate structured_type(), which returns
1406 non-zero if the argument is a structured type.
1407 Added the predicate pointer_type(), which returns non-zero
1408 if the argument is a pointer type.
1409 eval.c Added the ability to do addition and substraction on
1410 pointers and integers. This case simply bypasses the
1413 Thu Jul 11 14:41:42 EDT 1991
1416 Added the symbol N_DEFD (0x4a) which is a definition
1417 module dependency that is used by the GNU Modula-2
1418 compiler and the linker. It is not important to GDB,
1419 except that [dbx|coff|mips]read.c should ignore these
1422 Fri Jul 12 16:07:00 EDT 1991
1424 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
1425 0 in val_print(). Also added statements to the else part
1426 to coerce type (argument to val_print) to a pointer type
1427 if it is an "array of unspecified length".
1428 valops.c Added the function value_m2_string(), which returns a
1429 (value) value which is a constant string, whose type is
1430 (ARRAY [0..n] OF CHAR). The length field of the type
1431 structure is set to zero, so it will be interpreted as an
1432 "array of unspecified length".
1433 stack.c Moved the language/frame mismatch check to
1434 main.c:execute_command().
1435 main.c The working language is recorded each time
1436 execute_command() is executed. If working lang has
1437 changed during its execution, then the new
1438 language/type/range info is printed out for the user. If
1439 the working language does not match the language of the
1440 frame, a warning is issued.
1442 Sat Jul 13 16:16:39 EDT 1991
1444 eval.c Moved all the type-checking stuff for operators to
1445 language.[ch] language.c. This is so we can keep language-specific
1446 stuff (like for what type operators are defined) in
1448 language.[ch] Added the function binop_type_check(), which checks to see
1449 if its two (value) arguments are type-compatible with its
1450 opcode argument. The opcode should represent an operation
1451 involving an operator. Also added the macro function
1452 unop_type_check, which calls binop_type_check with a
1453 NULL second argument.
1454 expprint.c Added Modula-2 operators to the op_print_tab, so info
1455 expression.h break works correctly. Also added "op_string", which
1456 returns the string corresponding to the (enum exp_opcode)
1457 opcode that is its argument.
1460 Sat Jul 13 18:26:18 EDT 1991
1462 coffread.c Added code to record the type of function arguments with
1463 each paricular function. Code is very similar to that
1465 dbxread.c Moved add_param_to_type() to symtab.c
1466 symtab.[ch] Added function add_param_to_type() from dbxread.c
1468 *** NOTE: The above additions have not been tested.
1470 Mon Jul 15 12:50:47 EDT 1991
1472 langauge.[ch] Added the functions type_error and range_error, which work
1473 like error() except if the type/range mode is set to
1474 *_mode_warn, then they do not do a return_to_top_level(),
1475 but merely print a warning.
1476 Also changed [set|show]_[type|range]_command() to support
1477 the new "warn" feature.
1479 Thu Jul 18 17:50:54 EDT 1991
1481 mipsread.c Added code to record the type of function arguments with
1482 each particular function. Code is very similar to that
1485 *** NOTE: The above additions have not been tested.
1487 Fri Jul 19 11:19:10 EDT 1991
1489 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
1490 UMIN_OF_SIZE, which when given a size of a numeric type,
1491 return the maximum and minimum value it can hold. UMAX...
1492 and UMIN... return the result for unsigned types.
1493 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
1494 struct types. They call above macros.
1495 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
1496 avoid a name conlict with the above.
1497 c-exp.y Added range checking on numeric constants in
1498 parse_number() for completeness.
1499 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
1500 return 0 if working_lang is not language_c.
1502 Thu Aug 8 14:17:22 EDT 1991
1506 breakpoint.c Documentation strings of some commands changed to
1507 eliminate the references to the C language where
1510 Tue Aug 13 15:48:03 EDT 1991
1512 m2-exp.y Added qualified identifiers to the grammar. The semantics
1513 are slightly different from those of the GDB operator ::
1515 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
1516 type_exp, where type_exp is any valid type expression.
1518 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
1519 printcmd.c Modified ptype_command() so it actually parses the input
1520 (necessary for type expressions with scope qualifiers).
1521 Added the function ptype_eval() which expects an
1522 expression composed of one OP_TYPE element.
1523 *.[ch] Replaced all occurences of parse_c_expression with
1525 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
1527 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
1529 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
1531 Small fixes from Peter Schauer:
1533 * infrun.c (child_attach): Lint.
1534 * solib.c (find_solib): Handle shared libs version 2.
1536 Small fixes from David Wood:
1538 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
1542 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
1543 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
1545 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
1546 chars_per_line is at maximum (user typed `set width 0'). Fix
1547 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
1549 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
1551 * coredep.c: include ptrace.h where necessary.
1552 * mipsread.c(parse_lines): fix unsigned char problem that was
1553 messing up line numbers on SGI's and possibly other MIPS based
1555 * infrun.c (child_create_inferior): use better test to check
1556 return val from setpgrp().
1557 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
1558 for sgi/irix support.
1560 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
1562 * mipsread.c (parse_symbol): Put non-static procedures
1563 in the global block.
1565 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
1567 Patch together `text_start' and `text_end' for 29K port.
1569 * exec.c (exec_command): If NEED_TEXT_START_END, define the
1570 variables and set them based on the exec file.
1571 * am29k-tdep.c: declare text_start.
1572 * valops.c (call_function_by_hand): declare text_end.
1574 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
1575 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
1576 because machines that do this will also have to know to
1577 set NEED_TEXT_START_END. Besides, it was a redundant way to
1579 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
1580 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
1581 NEED_TEXT_START_END.
1583 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
1585 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
1587 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
1588 Pass MUNCH_DEFINE to munch whenever we run it.
1589 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
1590 format string; use 0x%x instead.
1591 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
1592 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
1593 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
1594 * inflow.c: Handle `short' process group IDs.
1595 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
1596 and check for ptrace errors.
1597 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
1598 (coff_symfile_init): Initialize text_bfd_scnum.
1599 (read_coff_symtab): Use it to find the text [and absolute?] sections.
1600 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
1601 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
1602 Merge target arm case with other "easy" cases. Add target
1603 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
1604 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
1606 * minimon.h, remote-adapt.c, remote-mm.c: Add.
1607 * munch: Cope with RT/PC putting fns in data segment.
1608 Restore ability to override `nm' by specifying MUNCH_NM.
1609 * xconfig/rtbsd, xconfig/ultra3: New host systems.
1610 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
1611 and remote-adapt. Remove encapsulated coff #define's (the
1612 support should go in BFD, and gdb shouldn't know or care).
1613 * tconfig/a29k-kern: Same, but for remote kernel debugging.
1614 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
1615 * tm-29k.h: Update BADMAG (though it should go away).
1616 Allow the register definitions to be overridden in another
1617 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
1618 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
1619 DUMMY_SAVE_GR96, for handling kernel calling conventions
1620 that use GR64+ rather than GR96+.
1621 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
1622 remote debugging of Ultra3 kernel. Includes tm-29k.h and
1623 overrides various things.
1625 * remote-mm.c (mm_attach, mm_wait): Handle attach like
1626 child_attach does, making a clean stop in the newly attached
1628 * remote-eb.c: Lint.
1630 * coffread.c: Make coffread independent of any particular
1631 variant of COFF. Avoid #include-ing any particular one except
1632 internalcoff.h. BFD now passes key values for symbol reading
1633 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
1634 and the symbol masks and shifts); use them.
1635 Remove obsolete end_of_text_addr.
1637 * exec.c: Remove unused include files.
1639 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1641 * Makefile.in (documentation targets): Pass $(M4).
1642 Bugfix from eggert@twinsun.com (Paul Eggert).
1644 * stack.c (down_silently_command): Check for stack existence.
1646 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1648 * Makefile.in (VERSION): Update to 4.0.3.
1650 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1652 * core.c (core_file_command): Print frame at coredump with
1653 its level number, by calling print_stack_frame.
1654 * frame.h: Add selected_frame_level, print_stack_frame.
1655 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
1656 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
1657 Change print_sel_frame and print_selected_frame callers to
1660 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
1661 * symfile.c (free_named_symtabs): Ditto.
1662 * main.c (main): wrap_here needs an arg.
1663 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
1664 (solib_add): Avoid noise.
1665 (solib_create_inferior_hook): Lint.
1666 (sharedlibrary_command): Move dont_repeat to here.
1667 * utils.c (error): Call wrap_here to force buffered output.
1669 Small patches from Peter Schauer:
1671 * coffread.c (start_symtab): Free any existing line_vector before
1673 (read_coff_symtab): Ditto for type_vector.
1675 * source.c (lines_to_list): New variable, replacing function.
1676 (all uses): Use as variable.
1677 (_initialize_source): Add 'set listsize' and 'show listsize'.
1678 * utils.c (lines_to_list): Remove function.
1679 * stack.c (print_frame_info): Use as variable.
1680 * defs.h (lines_to_list): Remove declaration.
1682 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1684 * breakpoint.c (insert_breakpoints): Restore warning about
1685 the program might be running in another process, but only for
1686 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
1687 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
1689 * utils.c (error): if error_pre_print is set, print the string
1691 * main.c (main, print_gnu_advertisement, print_gdb_version):
1692 Reformat legalese so it always prints, but acts as an "I'm here"
1693 message while symbols are being read. If any errors occur,
1694 print a few newlines to set off the message and start it at the
1695 left margin. Remove mention of "help" command, and don't yak
1696 about symbol reading.
1697 (catch_errors): Error string is now printed first in case of
1699 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
1700 suggest the "help" command.
1702 * Makefile.in (VERSION): Set to 4.0.2.
1704 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
1706 * .gdbinit: Remove useless "rr" command. Set complaints
1707 to 1 for people debugging gdb.
1709 * breakpoint.c, remote-vx.c: Reword strings printed by
1710 catch_errors callers.
1712 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
1714 * WHATS.NEW: "history write -> history save". Doc "write on/off".
1715 (Fix from kenc@viewlogic.com.)
1717 Fix some infrastructure to be able to cope with host and target
1718 machines with different sized basic types (ints, ptrs, etc).
1719 (Idea from pierre@la.tce.com (Pierre Willard).)
1721 * values.c (value_from_longest): Rename from value_from_long.
1722 Handle pointer types as well as integers, so that targets with
1723 different pointer sizes from the host can be accomodated.
1724 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
1725 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
1726 uses of value_from_long to value_from_longest.
1727 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
1728 the correct pointer type to value_from_long{est}.
1730 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
1732 * remote-vx.c: Remove obsolete code for calling functions via
1733 vxworks kludge interface (it referenced value_from_long).
1735 * valops.c (value_string): Find malloc with lookup_misc_func, not
1738 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1740 Make writing to files work properly. (Fixes to BFD are also needed.)
1742 * core.c (core_open): Open file ourselves, read or r/w, depending on
1743 write_files. Use bfd_fdopenr.
1744 * gdbcore.h (write_files): New variable.
1745 * exec.c (write_files): Define variable, add set&show for it.
1746 (exec_file_command): Use write_files to open for read or r/write.
1748 Make shared library reading happen automatically. These changes
1749 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
1751 * inferior.h (stop_soon_quietly): Add to exported variables.
1752 * infrun.c (child_create_inferior): call solib hook, if defined.
1753 (child_attach): call solib hook, if defined.
1754 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
1755 (find_solib): Use lookup_misc_func rather than hand-rolled.
1756 (symbol_add_stub): New stub for catch_errors.
1757 (solib_add): Avoid output if !from_tty. Catch errors rather
1758 than just calling symbol_file_add and bombing.
1759 (solib_create_inferior_hook): Interface with the target process
1760 to let it read and alloc shared libs, then figure out what it did.
1762 * core.c (validate_files): Fix typo, soften warning.
1763 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
1765 * utils.c (fputs_demangled): Avoid duplicate printing if
1766 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
1768 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
1769 (Fix from pierre@la.tce.com (Pierre Willard).)
1771 * main.c (catch_errors): Change argument to a char * from an int,
1772 since a char * can point to a struct full of glop, but an int
1773 is not guaranteed to be able to hold a pointer.
1774 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
1775 breakpoint_re_set_one, breakpoint_re_set): Adapt.
1776 * core.c (core_open, solib_add_stub): Adapt.
1777 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
1779 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1781 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
1782 by adding .NOEXPORT target.
1784 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1788 * Makefile.in (VERSION): Roll to 4.0.
1789 (gdb.tar.Z): Make refcard.ps as well, for shipment.
1791 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1793 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
1796 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
1799 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
1801 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
1802 reflect above name change
1804 * WHATS.NEW: correct pointer to refcard.
1806 * doc/gdb.texinfo: update New Features, Installing
1808 * doc/gdbint.texinfo: add short description of configure +template
1810 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1812 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
1814 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
1816 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
1817 tar file, add dependencies for referenced doc files.
1819 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
1821 * coffread.c, symfile.c, stack.c: saberized.
1823 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1825 * doc/refcard.tex: permuted Essential Commands sec
1827 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
1829 set/show symbol-reloading
1830 default set complaints 0
1832 RET-repeat disabled after prompted long displays
1833 processID (attach) interpretation of 2nd GDB cmdline arg
1835 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
1837 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
1838 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
1839 breakpoint.c, main.c: lint.
1841 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1843 Install new configuration scheme for GDB and friends.
1845 * config.sub: Translate ordinary names to three-part names.
1846 * configure: Use three-part names internally.
1847 * configure.in: Translate three-part names to filenames.
1849 * README, WHATS.NEW: Update for gdb-4.0.
1850 * Makefile.in: Roll VERSION to 3.99.
1852 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
1854 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
1855 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
1856 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
1857 to single structures rather than arrays; when passing
1858 their address, use &. This avoids trouble with bdead compilers.
1859 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
1860 instead. This avoids portability headaches.
1861 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
1863 * source.c (open_source_file): Avoid ANSI const bdeath by
1864 skipping declaration and then casting result value.
1865 * tm-hp300bsd.h: Clarify comment.
1866 * utils.c (strstr): Result is const char *; ANSI bdeath.
1867 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
1868 since system include file defines it differently from "defs.h",
1869 though the two are equivalent for our purposes.
1870 * tconfig/hp300bsd: Add m68k-tdep.o.
1872 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1874 * tconfig/sun*4: Remove warnings about system assembler.
1876 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1878 * mcheck.c: Avoid warning about undeclared abort fn.
1879 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
1880 it causes recursive calls to error() when used in cleanups.
1881 To do so requires that we make it a function, so we do.
1882 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
1883 * utils.c (do_cleanups): Remove the current cleanup from the
1884 chain *before* calling it, in case error() is called from it.
1885 The result won't be pretty, but won't be an infinite loop either.
1887 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
1889 * dbxread.c (read_struct_type): Grok anon structs for C++.
1890 (vb_name, vptr_name): Null terminate these strings.
1892 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1894 Minor bug fixes from BSD Net2 gdb:
1896 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
1897 returns 0, there is no previous frame.
1898 * breakpoint.c (commands_command): If !from_tty, don't call
1899 input_from_terminal_p().
1900 * dbxread.c (record_misc_function): Speed up slightly.
1901 (compare_psymbols): Ditto.
1902 * infcmd.c (do_registers_info): Take a second argument to
1903 determine whether to print float registers. "info registers"
1904 does not do so anymore. "info all-registers" does, now.
1905 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
1907 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
1908 * inflow.c (initialize_inflow): Set tflags_ours correctly.
1912 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
1913 executing_breakpoint_commands if we are interrupted by error.
1914 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
1915 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
1916 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
1917 catch_errors() so we can setup the frame regardless of whether
1918 the shared libs work.
1919 * ieee-float.c (double_to_ieee_extended): Get exponent from
1920 right place in little-endian systems. From John Carey.
1922 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1924 * main.c: Remove unused terminating_signals and catch_termination().
1925 (long_options): Terminate with a zero element.
1926 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
1927 (gdb_readline): Make call-compatible with readline.
1928 (init_signals): Improve comments re vfork vs. signal.
1930 * utils.c (prompt_for_continue): Use new gdb_readline().
1931 If we prompt for continuation, we don't let CR repeat the previous
1932 command, once we get back to a prompt. It's too easy to keep
1933 hitting CR, expecting "--more--" prompts, and have some long
1934 command start repeating on you.
1936 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1938 * blockframe.c (frameless_look_for_prologue): Speed up by
1939 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
1940 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
1941 Define two variants, one faster.
1942 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
1943 and return zero, rather than giving an error.
1944 (setup_arbitrary_frame): Initialize the PC in the new frame.
1945 (skip_prologue): Add a second arg saying whether we're just
1946 checking for a frameless function or not.
1948 * core.c (core_open, core_close, core_xfer_memory): Move
1949 section table pointers and bfd* into the target_ops.
1950 (core_open): Allow errors in shared lib reading, etc.
1951 (core_files_info): Describe shared library sections.
1953 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
1954 exec_files_info, set_section_command): Move section table
1955 pointers and bfd* into the target_ops.
1956 (add_to_section_table): Add BFD to section table.
1958 * target.c (target_xfer_memory, target_info): Pass target to
1959 xfer_memory and target_info functions.
1962 * gdbcore.h: Move struct section_table.
1963 * target.h: New home of struct section_table.
1965 * solib.c (solib_add): New argument is the target_ops whose
1966 section list is to be added to, if any. Reallocate the
1967 sections in that target to add any that come from shared libs.
1968 (throughout) so_sections renamed to sections.
1969 (solib_xfer_memory): Deleted.
1970 * tm-sunos.h (SOLIB_ADD): Add target argument.
1971 (SOLIB_XFER_MEMORY): Delete.
1973 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1974 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
1975 from target_ops. It's the same on all targets. Add two section
1976 pointers to target_ops.
1978 * stack.c (find_relative_frame): Dump ancient algorithm for
1979 "down", just use handy "next" pointers.
1980 (frame_command): Don't error if there is no stack; let user
1983 * inflow.c (new_tty_prefork, new_tty): New prefork routine
1984 modifies static state in the parent process; new_tty itself
1985 runs in the child and modifies the child's file descriptors
1986 to match the saved static state.
1987 * infrun.c (child_create_inferior): Call new_tty_prefork,
1990 * infptrace.c (child_xfer_memory): Add ignored target arg.
1991 * remote-eb.c (eb_xfer_inferior_memory): ''
1992 * remote-nindy.c (nindy_xfer_inferior_memory): ''
1993 * remote-vx.c (vx_xfer_memory): ''
1994 * remote.c (remote_xfer_memory): ''. Rename from
1995 remote_xfer_inferior_memory.
1997 * main.c (main): Only try to attach "corefile" argument if
1998 it starts with a digit.
2000 * symfile.c (symbol_reloading): New "set/show" variable.
2001 (symbol_file_add): Shorten message about symbol reading.
2002 (add_symbol_file_command): Merge with add_syms_addr_command,
2003 since this should work on all targets now.
2004 (stop_whining): Default to zero, to shut up complaints
2005 about bad symbol tables on many systems.
2006 (free_named_symtabs): Just exit unless symbol_reloading.
2008 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
2009 and add comment explaining shared library screw.
2011 * source.c: #if defined => #ifdef.
2013 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2015 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
2017 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2019 * doc/rdl-apps.texinfo: provide default readline-appendix finder
2020 (doc/Makefile knows how to make one for local config)
2022 * Makefile.in: use doc/Makefile for doc targets
2024 * doc/Makefile: GDB documentation now has its own Makefile
2025 doc/refcard.tex: renamed from "gdbrc.tex"
2026 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
2027 doc/gdbint.texinfo: add markup in "Cleanups" chapter
2030 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2032 * values.c (baseclass_addr): When reading target memory, use the
2033 length of the basetype, not the upper type. We've only malloc'd
2034 enough space for the basetype, leading to errors in free().
2036 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
2037 ends up as a function specially, since we know the actual type of
2038 the pointed-to address. This (somewhat) fixes display of
2039 expressions that include misc_function_vector names. Try `cond 1
2040 !strcmp("a","b")' then `i b'.
2042 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
2043 The child can be proceeded from inside wait_for_inferior in
2044 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
2045 getting skipped in that case.
2047 * expprint.c (print_subexp): Use filtered output, since the
2048 subroutines we call use it, otherwise the output is horribly
2049 mangled, since output of wrappable stuff comes out late.
2051 * Makefile.in: Bump VERSION to 3.98.1
2053 * infrun.c (child_create_process): Use execlp to find the
2054 shell to exec our target program. This requires some fiddling
2055 with `environ' since there is no execlpe().
2057 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2059 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
2060 Minor rearrangement of refcard permits two new make targets--
2061 gdbrc.dvi DVI output for refcard, using CM fonts
2062 gdbrc.ps PostScript refcard, using PS fonts
2064 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2068 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
2069 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
2071 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2073 * doc/gdb.texinfo: last changes for release.
2074 Minor typo and formatting fixes; incorporated most fixes remaining from
2075 filed mail commenting on earlier drafts.
2077 Added warnings: pipes don't work in run command;
2078 conditions are converse of assertions;
2079 step over fn without debug info goes to next fn;
2080 vars may have "wrong" values near fn entrance, exit
2082 Added example from Kingston on printing repeated nonadjacent values
2084 Added explicit mention that in Emacs gdb mode C-c and C-z are like
2085 shell mode for signals
2087 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
2088 doesn't sound so much like its parent "Stopping and Continuing"; also
2089 moved entries on continue to top of section, so they don't get lost.
2091 Improved installation directions in appendix, added manual formatting
2094 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2096 * configure.in: Remove xm.h and tm.h even if we aren't linking
2097 new ones, so "./configure sun4; ./configure none" does the right
2098 thing. Assume that alldeps.mak and depend are already built in
2099 srcdir, and avoid running "make" (particularly "make depend",
2100 which involves "gcc") from inside configure. Build Makefile
2101 directly rather than building Makefile.conf first.
2102 * configure: Regenerate with above changes.
2103 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
2104 to 3.98. Revise gdb.tar.Z procedure to produce a file
2105 called gdb-$(VERSION).tar.Z but which unpacks into a
2106 directory called "gdb". Move non-source files out of
2107 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
2108 (depend): Don't try to do "gcc expread.y".
2109 (expread.o): Update dependencies by hand.
2111 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2114 Fixed a variety of small typos that prevented info from formatting
2115 cleanly; altered too-long heading for GPL Appendix, as discussed
2116 w/RMS; Changed date on cover to July 91.
2118 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2121 (1) Applied some fixes due to comments from Larry Breed (easier ones
2122 through chapsec 5.2)
2123 (2) Eliminated use of @footnote---had my doubts about it anyways, and
2124 it's broken in latest texinfo
2125 (3) Introduced *some* use of [] for optional arguments, where
2126 explanation is not simpler by listing cmd w arg and cmd w/out arg
2127 separately. Still not using @deffn.
2128 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
2129 couple of headings are too long. Need patches to texinfo or revision
2132 * Partial update to README (which still needs work for this
2133 release!): (1) use of configure corrected for new script,
2134 (2) "make gdb.dvi" and "make gdb.info" mentioned.
2136 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
2138 * symtab.c (lookup_symbol): Don't complain right off about
2139 no debug symbols; use the misc function vector first.
2140 (list_symbols): Use misc function vector to find symbols
2141 that don't have debug info, and print them.
2142 (find_pc_symtab): Temporarily avoid fatal() when psymtab
2143 PC range doesn't match symtab PC range, as it does on the
2144 MIPS because our symtab reading isn't perfect.
2146 * dbxread.c (dbx_symfile_read): Make warning about
2147 "no debug symbols" slightly nicer.
2149 * source.c (select_source_symtab): If "main" symbol exists,
2150 but decode_line_spec can't find line info, don't just return
2151 a zero; try other source symtabs or give an error.
2153 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
2154 their low addresses first, then rip through fixing high addrs.
2156 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
2157 <runene@ifi.uio.no>.
2158 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
2160 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2162 * Minor, mostly mechanical, cleanup of doc subdir for clean
2163 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
2164 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
2166 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
2168 Mostly MIPS and general symbol-reading fixups.
2170 * doc/gdbint.texinfo: Add documentation on symbol-reading
2173 * mipsread.c: Remove kludges around #include "ecoff.h".
2174 Remove redefinitions of a_magic, etc, no longer used.
2175 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
2176 Fix global overview comments to match symfile.c protocol.
2177 (mipscoff_new_init): Eliminate cur_hdr if we have one.
2178 (mipscoff_symfile_read): Eliminate unused code. Avoid
2179 sorting all the symtabs, when all we have read here is psymtabs.
2180 The symtabs are sorted as they are created anyway. Tell
2181 condense_misc_bunches whether we're mainline.
2182 (psymtab_to_symtab_1): Pass filename when recursing, to make
2183 stack trace more informative.
2184 (parse_partial_symbols): Assume cur_hdr as argument.
2185 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
2186 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
2187 the TYPE_NAME of char *, since that's done in symfile.c.
2188 (free_numargs, parse_symbol, add_symbol, add_block,
2189 shrink_linetable): Declare these fns void.
2190 (upgrade_type): Convert tree of if's to switch. Clean up
2191 bogus "off == 0" handling with a complaint. Avoid setting
2192 field bitpos and bitsize of array with lower and upper bounds.
2193 Check specified bitsize of elements against their actual type's
2194 bitsize, and complain if different. Complain about unknown
2196 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
2197 (psymtab_to_symtab_1): Print names of subsidiary files that
2198 are being read in. FIXME, we read far too many files. This code
2199 is not the problem, the problem is in parse_fdr where the psymtabs
2201 (cross_ref): Result should indicate that we used one aux entry
2202 normally, or two if we encountered a "next" entry. This used
2203 to leave the caller pointing at the wrong aux entry.
2204 (add_symbol): If overflowed cur_block, reallocate it larger,
2205 chase all pointers to it, and complain(), rather than clobber memory.
2206 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
2207 (new_field): Only allocate one field initially, not two.
2208 Pull ++ out of macro argument. Simplify.
2209 (_initialize_mipsread): Avoid initialization of importd
2210 global_psymbols and static_psymbols.
2212 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
2213 to properly set pst->symtab; avoid searching for it.
2214 (symfile_fns): Improve comments, add a FIXME.
2215 * dbxread.c: Update comments to reflect symfile protocol.
2216 (read_ofile_symtab, end_symtab): Return the symtab.
2217 (psymtab_to_symtab_1): Set pst->symtab.
2219 * coffread.c (coff_symfile_read): tell condense_misc_bunches
2220 whether we're mainline.
2222 * symfile.h (sym_fns): Remove unused sym_discard member.
2223 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
2225 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
2226 the environment variable is not.
2227 * infcmd.c (finish_command): Use filtered printfs.
2228 * cplus-dem.c: Add struct tags to a few unnamed structs.
2229 * valops.c (value_coerce_array): Improve comments.
2230 * valprint.c (type_print_varspec_suffix): Print array size only
2231 if greater than zero.
2232 * m88k-tdep.c: Shift some lines left by one space, that had
2233 apparently been trashed at some point.
2234 * TODO: More things to do, a few got done.
2236 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2238 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
2239 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
2241 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
2242 * expread.y, findvar.c, symmisc.c: Ditto.
2243 * printcmd.c (address_info): Update printed forms of LOC_
2244 symbols. Elim LOC_EXTERNAL.
2245 (print_frame_args): Keep track of param stack offsets before
2246 re-looking up to find the local register param is kept in.
2248 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
2249 Further integration of mipsread into gdb. Eliminate unused
2250 routines, duplicate declarations. Handle static symbols in
2251 psymtabs as well as external symbols. When reading symtabs,
2252 insert symbols into the correct block (global, static, or a local
2254 (read_mips_symtab, parse_partial_symbols): Don't pass useless
2256 (mipscoff_symfile_read): Don't call select_source_symtab.
2257 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
2258 rather than SYMBOL_VALUE.
2259 (parse_external): Comment clobbering of top_stack.
2260 (parse_partial_symbols): Update comments. Allocate and parse
2261 static symbols as well as external symbols. FIXME, enum values
2262 are not handled in this pass, but should be. Inline new_psymbol.
2263 Use SYMBOL_VALUE_ADDRESS.
2264 (psymtab_to_symtab_1): Read symbols into global static block
2265 by default (until enter some function's local block context).
2266 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
2267 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
2269 * source.c (select_source_symtab): Select a source symtab
2270 from either the symtabs or, failing that, the psymtabs.
2271 (list_command): Update error message.
2272 (forward_search_command, reverse_search_command): Use getc, not
2273 fgetc, for speed. FIXME, add comment about buffers that die if
2274 overrun by long line.
2276 * values.c (unpack_field_as_long, modify_field): Avoid shifting
2277 by an entire word, which is not portable, if we have a 32-bit
2278 field. (Code in dbxread.c already turns such bitfields, if
2279 aligned, into ordinary ints, but fixing this will help for other
2280 symbol formats and for future changes.)
2281 * core.c (core_open): Handle ANSI const brain death.
2282 * utils.c (vprintf): Fix varargs typo.
2284 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
2286 * findvar.c (find_var_value): Handle &function better.
2287 * TODO: Document work needed on &fn and &array.
2288 * printcmd.c (print_address_symbolic): New arg is the prefix
2289 to print if a name is printed.
2290 (print_address_demangle): Honor "set print address" now.
2291 Use new arg above to improve spacing of output.
2292 * valprint.c (val_print): When printing function pointers,
2293 print symbolic form too.
2294 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
2296 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2298 * core.c (memory_error): Reword error msg to mislead less.
2300 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
2302 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
2303 parse_partial_symbols): Use newer BFD internals (external_filehdr
2304 and external_aouthdr), byte-swap the fields that we care about
2305 before using them, and make the file header data local to
2306 read_the_mips_symtab rather than global.
2308 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
2310 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
2311 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
2313 * main.c (command_line_input): Flush stdout and stderr
2314 before every call to readline. This reportedly fixes a bug
2315 that comes up in Sys V running emacs-gdb and/or xxgdb,
2316 when stdin/out are pipes or sockets.
2318 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2320 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
2321 Avoid declaring Makefile dependencies, because GNU Make stupidly
2322 tries to update it if we do.
2324 * coffread.c: Revise for minor changes to bfd internal coff
2327 * configure: If -template= is given a relative path, make it
2328 absolute before recurring in subdirectories.
2330 * configure, configure.in, Makefile.in: Install "configure" script
2331 as replacement for config.gdb.
2332 * config.gdb, Makefile.dist, Makefile.sdir: Remove
2333 * README: Update for configure, mostly. FIXME.
2335 * Add dec3100 as equivalent to littlemips. Indicate in all host &
2336 target config files that they are for the host. When the lines
2337 get copied into the Makefile, this makes it more obvious what's
2340 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2342 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
2343 tabs, which end up in the disassembler output inadvertently.
2345 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
2347 Make it compile cleanly in an ANSI GCC2 environment.
2349 * blockframe.c: <stdio.h>
2350 * cplus-dem.c: free takes a void *, ifdef __STDC__
2351 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
2353 * defs.h (alloca): Avoid doing anything if alloca already def'd.
2354 * stddef.h, stdlib.h: Remove these files.
2355 * symtab.c: Avoid declaring qsort, close.
2356 * symfile.c: Avoid declaring close.
2357 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
2358 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
2360 Assorted other changes.
2361 * dbxread.c: include "libaout.h", not "liba.out.h".
2362 * printcmd.c (print_frame_args): Set recurse properly for
2363 indentation of struct and array parameters.
2364 * valops.c (value_cast): Allow cast to void.
2365 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
2366 single_step() in a target-independent fashion.
2367 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
2368 set up to be ready to continue. This makes us target independent.
2369 * infptrace.c (child_resume): Remove call to single_step; now
2370 can single step a SPARC target of any kind.
2372 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2374 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
2375 docn into separate sections---basically chapters, plus two loose
2376 pieces that can be configured to go in different places. This
2377 allows GNU m4 to preprocess the manual without coredumping.
2379 * Makefile.dist: tell TeX where to find texinfo.
2381 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2383 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
2384 the new target "rdl-apps.texinfo" which captures the Makefile
2385 variable that records where to find the Readline libraries.
2387 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
2389 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
2390 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
2391 * defs.h (const, volatile): Only define if not already defined.
2392 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
2394 * README: Update for release 3.95.
2395 * config.gdb: Don't create readline dir in subdir builds.
2396 * main.c: Include with "..." form for non-system include files,
2397 so "gcc -MM" for "make depend" works.
2398 Include readline files with "...h" rather than <readline/...h>.
2399 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
2401 * coffread.c: Undo minor damage done by Rich Pixley. Use
2402 different internal and external representations of COFF
2403 data structures. Use new BFD routines for swapping them in and
2405 * symfile.c (free_named_symtabs): Avoid freeing file names that
2406 are null or empty. Old i960 tools seem to produce files that
2407 claim to have empty names, causing each successive file read
2408 to blow away the previous one.
2409 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
2410 Move deferred_stores to top of file, but don't separate its
2411 #define's from its variable. Add commentary.
2412 * Makefile.dist: Fix Rich damage; undo "configure" changes in
2413 favor of keeping the (working) config.gdb. Move readline
2416 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
2418 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
2420 * infptrace.c (fetch_registers): no result, since now void.
2421 * tconfig/news: target depends on m68k-tdep too.
2423 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2425 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
2428 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
2429 applied various small fixes due to or inspired by RMS comments
2431 * doc/gdb.texinfo: finished using all RMS comments, save those for
2432 appendices on readline and cmd history (which are in other source
2435 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2437 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
2438 chapter 9; (2) documented 'break' command's menu mode for
2439 overloaded names, in response to hgs problem report C++ p-31
2441 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2443 * doc/gdb.texinfo: (1) better introductory example; (2) more
2444 consistent use of @code, @samp, @file, @kbd throughout; small
2445 cleanups to first three nodes; (3) new "Contributors" node;
2446 (4) Appendix, Renamed Commands; (5) divert specialized startup
2447 instructions to "Targets" chapter for generic manuals, while
2448 leaving them up front for manuals specific to specialized
2449 environments; (6) apply fixes from RMS comments through chapter 4.
2451 * pretex.m4: modify explanatory text slightly (and redefine
2452 "regexp") to keep GNU m4 from complaining. (It still crashes
2453 later, but one step at a time...)

2457 * readline/readline.c (update_line): Avoid dereferencing a pointer
2458 before comparing it to its bounds. Saber caught this.

2464 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
2465 stuff for config manual) here where it counts; updated
2466 to use new subdir structure (gdb/doc/).
2468 * Makefile: generated from above via
2472 * gdbint.texinfo: added instructions on generating gdb.info* files
2473 locally for release. These are ordinary info
2474 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
2475 Makefile)---but due to use of texinfo 2, can't count on makeinfo
2476 to generate these, so we distribute them already formatted.
2478 * gdb.texinfo: included full Info node and menu crud (as generated
2479 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
2481 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
2482 put in comments-for-future gdb.info target (one day makeinfo will
2485 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2487 * gdb.texinfo: Updated to include new or old undocumented
2488 commands, at least the following (perhaps some others I forgot to
2489 record): info f, info float, info path, info program, info s, info
2490 set, info source, info terminal, info types, info user, set/show
2492 Also covered all recent GDB command renames for v4.
2494 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2496 * mipsread.c: Rather than keeping count of how many symtabs
2497 and psymtabs we have, for sorting purposes, count them when
2498 we need to sort. This fixes bug in rereading of symbol tables.

2517 symtab.h, target.c, target.h: Lint.
2518 * core.c: setup and select frame after reading shared libs,
2519 else reading shared libs will clobber them. Lint.
2520 * utils.c (error): Force out any buffered wrap text.
2522 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2524 * remote.c: Remove decls of memory_insert_breakpoint
2525 and memory_remove_breakpoint, no longer used. (Suggestion of
2528 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
2529 to make it easier to interface to "configure"'d libraries.
2531 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
2533 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
2534 aliases for set/show print.

2925 before returning locals or slocals.
2927 * i386-tdep.c (i386_follow_jump): Do not add data16 to pos in

2959 tm-sun3.h: Define TARGET_SUN3.
2961 * utils.c: Use CPLUS_MARKER not '$'.
2963 * cplus-dem.c: Use CPLUS_MARKER not '$'. If CPLUS_MARKER isn't
2964 defined, define it to '$'.
2966 * arm-opcode.h: New file (same contents as before; it had
2967 just been left out of the distribution for a long time).
2969 * tm-68k.h: Put declaration of ext_format_68881 outside the macros.
2971 * main.c: New HAVE_SIGSETMASK #ifdefs.

2991 Makefile.dist: Add it to $(OBS).
2993 * mipsread.c [!CMUCS]: #include <syms.h>.
2995 * mips-xdep.c (fetch_core_registers): #if 0 out the whole function.
2997 * Move read_memory_nobpt from mem-break.c to breakpoint.c.

3037 * inftarg.c (child_open), remote-vx{,.68}.c (vx_proc_open):
3038 New function to give correct error message.
3040 Thu Apr 11 17:19:41 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
3042 * target.h: Add to_doc and target_preopen.
3043 target.c: Add target_preopen and target_command.
3045 (add_target): Call add_cmd and mess with targetlist->doc.
3046 core.c, exec.c, remote-eb.c, remote-nindy.c, remote-vx.c,
3047 remote-vx.68.c, inftarg.c, remote.c: Add doc field to target struct.
3048 Call target_preopen from open routine.
3050 * main.c: Rename editing_info to show_commands.

3065 Rename add-syms to add-symbol-file.
3067 Thu Apr 18 18:08:30 1991 John Gilmore (gnu at cygint.cygnus.com)
3069 * symfile.h (free_named_symtabs): Rename from free_named_symtab.

3071 free_named_symtabs): Move these routines from symmisc.c.
3072 * symmisc.c (same): same.
3073 (free_symtab): Make non-static.
3074 * symtab.h (free_symtab): Declare as exported void fn now.
3075 * dbxread.c (end_symtab, end_psymtab): Change comments.
3076 (initialize_dbxread): Call dbx_new_init() in case the first
3077 command is add-symbols.
3078 * target.c (dummy_target): Permit add_syms_addr_command.
3080 Sat Apr 13 14:46:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3082 Permit symbols to be superseded when new symbol files have
3083 been read in, particularly for VxWorks.
3085 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
3086 to the main file, as well as to include files. Also, put global
3087 functions into the global psymtab, to make "i fun" work.
3088 (end_psymtab): Free named symtabs and psymtabs for a file, once a
3089 new psymtab for it has been read.
3090 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
3091 a file, once a new symtab has been read for it.
3092 * mipsread.c: FIXME. We need to do the same for MIPS, but it
3093 looks harder to determine the top-level block before it's been
3094 queued to the psymtab list.
3096 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
3097 If we have wiped out any old symbol tables, clean up at end of
3099 (symbol_file_command): Don't reference symfile_fns if it's zero.
3101 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
3102 defines for the blocks of a blockvector that contain global and
3103 file-static symbols and the first of the smaller scope contours.
3104 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
3105 decode_line_1, make_symbol_completion_list): Use the above.
3106 * coffread.c (end_symtab, patch_opaque_types): Ditto.
3107 * dbxread.c (end_symtab): Ditto.
3108 * expread.y (block): Ditto.
3109 * mipsread.c (throughout): Ditto.
3110 * symmisc.c (free_named_symtabs): Ditto.
3112 * symtab.c (list_symbols): Process the first symbol of the
3113 static psymbols list.
3114 (types_info): Restore this function from its untimely #if 0.
3115 It's not perfect, but it is better than nothing.
3116 (_initialize_symtab): Restore "info types".
3118 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
3120 * m68k-stub.c: Remote stub for 680x0's, created from
3121 rem-m68k.shar (which is removed).
3122 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
3123 Remove RCS log stuff now that we use CVS and it blows our diffs.
3125 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
3127 * symmisc.c (free_named_symtab): Make it work, in its current
3128 kludgy fashion. Change result to indicate if we blew away bkpts.
3129 * dbxread.c (end_symtab): Accumulate result from
3130 free_named_symtab and print warning if we blew user's state.
3131 * symfile.h: free_named_symtab now returns an int.
3133 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
3135 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
3136 is the first symbol read, even if not mainline.
3137 (dbx_psymtab_to_symtab): symfile might be zero, cope.
3138 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
3139 (set_section_command): New command ("section xxx yyy" -- should
3140 be renamed to "set section xxx yyy" FIXME) which sets the
3141 base address of a section of the exec file, overriding the
3142 virtual address that BFD reports.
3144 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
3146 * exec.c: Add add_syms_addr_command to exec_ops, so you can
3147 load symbols at any address while examining an exec file.
3149 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3151 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
3152 for printing the float info is host-dependent, not
3153 target-dependent. FIXME.
3154 * i386-pinsn.c: Move #includes to top, remove useless ones.
3155 * i386-tdep.c: Don't bother including <.../reg.h> since we
3156 don't use it (and it doesn't exist on host systems).
3158 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
3159 Convert negative numbers properly.
3160 (ieee_test): Make numbers really random; fix format arg.
3162 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
3163 * core.c (core_detach): Unpush core_ops, which might not be on
3164 top. We used to just pop the top, which broke things. Don't
3165 need dont_repeat() any more.
3166 (core_file_command): Psst! Don't repeat it.
3167 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
3168 * expprint.c (print_subexp): Avoid switch fallthru on
3169 BINOP_ASSIGN_MODIFY, so we can print += and such.
3170 * frame.h: Fix typo.
3171 * inflow.c (kill_command): After killing inferior, print our
3172 current frame in the core file, if we have one.
3173 (generic_mourn_inferior): When inferior dies, either select
3174 the current frame (in the new target, e.g. core file), or
3175 set both the current and selected frames to NULL.
3177 Changes from Peter Schauer.
3179 * infptrace.c: Avoid <sys/ptrace.h> on USG.
3181 * Make all file names fit in 14 characters (sigh and damn!):
3182 mv hp300hpux-xdep.c hp300ux-xdep.c
3183 mv symmetry-xdep.c symm-xdep.c
3184 mv symmetry-tdep.c symm-tdep.c
3185 mv convex-opcode.h convx-opcode.h
3186 mv tm-vxworks960.h tm-vx960.h
3187 mv tm-vxworks68.h tm-vx68.h
3188 mv Makefile.srcdir Makefile.sdir
3189 mv gdb-int.texinfo gdbint.texinfo
3190 mv remote-sa.m68k.shar rem-m68k.shar
3191 mv remote-multi.shar rem-multi.shar
3192 * Makefile.dist, README, config.gdb, convex-pinsn.c,
3193 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
3194 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
3197 * command.c (user_info_1, user_info): New command for listing
3198 the user-defined commands.
3200 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
3202 * dbxread.c (really_free_pendings): Clear file_symbols
3203 and global_symbols after freeing them; otherwise, running
3204 this function twice (if it appears twice on the cleanup
3205 chain), we try to free things twice.
3207 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
3208 based on text_addr (the address of text in core), not on addr (the
3209 offset between text in the .o file and in core). This change
3210 is from Peter Schauer.
3212 * main.c: Define ALL_CLEANUPS as a cast of zero.
3213 (return_to_top_level): Use it.
3214 (main): Do all cleanups after each command run as part
3215 of the gdb startup sequence. Also do all cleanups before
3216 entering the command loop, and every time we exit the command
3217 loop and reenter. Before, the cleanups from the startup sequence
3218 were being left undone until the first error!
3219 (command_loop): Rename do_nothing cleanup to command_loop_marker
3220 so we can see it easily when examining the cleanup chain.
3221 (init_signals): Add another do_nothing for signal handling.
3222 (quit_command): Only try to kill target if it has execution.
3223 Problems in the target stack got us into a state where
3224 inferior_pid was nonzero but none of the targets had execution.
3225 In this state you couldn't exit gdb.
3227 * dbxread.c: Two changes from Peter Schauer.
3228 (echo_command): Fflush output after an echo command.
3229 (show_history): Pass all args to cmd_show_list.
3231 * utils.c (init_malloc): Call mtrace to turn on tracing
3232 if the environment variable MALLOC_TRACE is set to a file name.
3233 * mtrace.c: Add source file which provides a log of every malloc,
3234 free, and realloc to a trace file.
3235 * mtrace.awk: Add source file which analyzes the trace file.
3236 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
3237 (VERSION): Roll to 3.94.3.
3239 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
3240 (check_duplicates): Don't bother with watchpoints.
3241 (set_raw_breakpoint): Comment about danger of this routine.
3242 (watch_command): Parse and eval all args before calling
3245 * solib.c (find_solib): Avoid error in referencing memory to
3246 see if any more shared libraries have been added. This is
3247 particularly useful if the target has terminated. Bug reported
3250 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
3251 in bringing up 3.94.2 on the Sun-3.
3253 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
3254 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
3255 expression (in scope) before reenabling watchpoint.
3256 * signame.c (init_sigs): Add missing declaration of i, fix
3257 sys_siglist declaration.
3258 * source.c (list_command): Fixed range computation to use
3260 * stack.c (backtrace_command): Do not allow command if target has
3261 no stack, print informative error message.
3262 * target.c (target_command): Do not write into command line
3263 because this fails if the target command is used in a user defined
3264 command. [This change was enhanced by gnu to support any-
3265 unique-prefix matching on target names.]
3266 * valops.c (value_struct_elt): Avoid infinite loop on an
3267 erroneous attempt to print the member of function (try p main.p).
3269 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3271 * expread.y (name_no_typename): Avoid reduce/reduce errors
3272 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
3273 Since the GDB parser really doesn't use name_no_typename in a
3274 name-only context, the parser can't tell the diff between
3275 names and numbers here. Avoid allowing a name_no_typename
3276 to be a NAME_OR_*INT to resolve the conflict.
3278 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3280 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
3282 * valprint.c (val_print_fields): bitfield printing didn't handle
3283 byte order. Indirect through a few more fns to cope.
3285 * values.c (modify_field): also cope with byte order.
3287 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
3289 Cleanup for release 3.94.2:
3291 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
3292 include files. Roll version to 3.94.2.
3294 * coffread.c (init_stringtab): Read length into unsigned char
3295 array before swapping; don't assume 32-bit longs.
3297 * target.c (target_info): Don't bother with get_sym_file, just use
3298 the symfile global variable.
3299 * symtab.h, symfile.c (get_sym_file): Delete it.
3301 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
3302 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
3303 (read_type): Replace one more error() with complain().
3305 * mipsread.c (parse_partial_symbols): Replace printf with complain.
3307 * i960-tdep.c: Fix copyright attribution.
3309 * config.gdb: Quote all backquotes in doublequotes. You can
3310 quote me on that. BSD 4.4 shell found this one.
3312 * infptrace.c (throughout): The third argument to ptrace is an
3315 * infrun.c (wait_for_inferior): When program has terminated, we
3316 have to call target_terminal_ours before we pop that target off
3317 the stack (e.g. before a call to target_kill or
3318 target_mourn_inferior). This fixes problem where a program
3319 terminates, then GDB stops for (tty output) and you have to type
3320 "fg" to the shell to resume it. FIXME: This code for what to
3321 do after termination really should be in normal_stop instead.
3323 * gdbcore.h (read_memory_check): Change declaration; it changed
3326 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
3327 4.4 prereleases, this avoids a bug in their sgtty compatability
3329 * remote.c: Use terminal.h rather than hand-rolling the same.
3331 * signame.c, signame.h (psignal): Arg is unsigned, not int.
3332 * utils.c (strsave, strstr): Fix arg types.
3333 * valprint.c (val_print): lint
3335 MIPS symbol table support from Per Bothner:
3337 * symfile.c (symtab_fns): Remove initializer table that needs to
3338 be hacked for each new symbol file format supported.
3339 (add_symtab_fns): New function, chains symbol table
3340 handlers into the global list.
3341 (symfile_init): Search this list.
3342 * symfile.h: Add next pointer, declare add_symtab_fns.
3343 * coffread.c (_initialize_coffread): Call add_symtab_fns.
3344 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
3346 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
3347 symbol *). Thus, we no longer need the hack to trash
3348 pst->filename. Good, since that hack confused code in symfile.c!
3350 (reorder_symtabs, destroy_all_symtabs): Removed static
3351 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
3352 Instead, the latter now uses a temporary array (stack-allocated
3353 from an obstack, and then freed).
3355 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
3356 haven't been set in the outermost stBlock of a procedure. This was
3357 a problem with f77 binaries on Ultrix 4.?.
3359 (new_symtab, new_symbol, new_type): Continue changing code to use
3360 obstacks more and otherwise conform to dbxread internal style.
3361 Made the free_code of symtabs be free_linetable (as in dbxread)
3362 instead of free_contents. This implies memory leaks when reading
3363 a new symbol table, until the conversion is finished. Did change
3364 (struct symbol) and (struct type) to be allocated on the
3365 symbol_obstack. Blocks and blockvectors are among the things
3368 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
3369 tested much, but it solved one problem (reported by Meissner), and
3370 cleans up some other things. The problem happened when an
3371 included file contains actual code (functions) and not just
3372 definitions. The mips coff is a little inconvenient there, since
3373 it may cause a procedure to be mapped to the wrong psymtab.
3375 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
3376 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
3377 this will need work for the new core paradigm.
3379 Opcode patches from the net:
3381 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
3382 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
3383 missing altogether - they are added here. From Bruce Bauman.
3384 * mips-opcode.h: The low mask for C0 instructions was too small.
3385 From Garrett Lau. I modified the fix to check the entire 32-bit
3388 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
3391 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3393 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
3395 * dbxread.c (read_type): Pointer subtraction (value_sub in
3396 valarith.c) sometimes failed because the types of the
3397 pointers being subtracted were not identical.
3398 These differed because dbxread.c was allocating pointer types
3399 using dbx_alloc_type+smash_to_pointer_type instead of
3400 lookup_pointer_type. I failed to find a justification for the
3401 former, so I changed it to use the latter. Similarly, I
3402 replaced smash_to_function_type by lookup_function_type,
3403 and smash_to_reference_type by lookup_reference_type.
3405 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
3406 _initialize_mipsread): corresponding changes.
3408 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
3410 * source.c (mod_path): Do tilde_expand on each component of the path,
3411 rather than on the (list of) paths as a whole.
3412 (print_source_lines): Set first_line_listed in addition to
3413 current_source_symtab and current_source_line. If the source was
3414 not findable, after a "dir" command to fix the problem,
3415 a "list" would get the wrong lines.
3417 While I was there... (gnu):
3419 * dbxread.c (read_type): Change error to complaint.
3421 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3423 First attempt at detailed understanding of symbol table memory alloc.
3425 * dbxread.c (dbx_symfile_read): Free our string table if we
3426 aren't the mainline. Free the "info" struct since we're done with
3428 (init_psymbol_list): Free any previously allocated psymbol lists.
3429 (): FIXME: Should realloc-down the psymbol lists when done reading
3430 the main symbol file?
3432 * symmisc.c (free_symtab): Free fullname field too.
3434 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
3435 (REGISTER_ADDR): Make result type unsigned int.
3437 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
3438 define REGEX must also define REGEX1 (its dependency).
3440 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
3442 * tconfig/i960: No longer works, points you at vxworks960 or
3445 * xgdb.c, XGDB-README: Remove file. Users can get the much
3447 * Makefile.dist: Remove all trace of xgdb.
3449 * breakpoint.c (breakpoint_1): Pass demangle arg to
3450 print_address_symbolic.
3451 (clear_breakpoints): Remove unused function.
3452 (breakpoint_re_set_one): Guts of breakpoint_re_set.
3453 (breakpoint_re_set): Use catch_errors to do them all anyway.
3455 * gdb-int.texinfo (Host versus Target): Add section on what is
3456 a "host" feature versus what is a "target" feature.
3458 * infcmd.c (path_command, path_info): Handle the PATH variable
3459 (object search path) as conveniently as the source search path.
3460 * environ.c (set_in_environ): Set some vars in GDB's environment,
3461 in addition to the child's. PATH, G960BASE, G960BIN for starters.
3462 * source.c (mod_path): New function, from guts of
3463 directory_command, modifies a path. Used by path_command.
3464 (directory_command): Call it.
3465 * defs.h (strsave): Declare.
3467 * utils.c (sevenbit_strings): Add new printing option.
3468 (printchar): Use it.
3469 (strsave): Provide this handy helper routine.
3470 (set_width_command): Rename set_screen_width_command.
3471 (_initialize_utils): "set screen-width" => "set width";
3472 "set screen-height" => "set height"; add sevenbit-strings.
3474 * infcmd.c (do_registers_info): Print floating point registers
3475 in raw hex as well as float format, regardless of whether it is
3476 a "virtual" convertible register.
3477 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
3478 regs as a double, just in case it's being used that way.
3479 * values.c (unpack_long): Comment on array/function coercion.
3480 (unpack_double): Argument is in target byte order now. For
3481 integer arguments, just call unpack_long and float the result.
3482 * m68k-tdep.c: include defs.h for "const" handling.
3483 * remote-nindy.c: Use ieee-float stuff.
3484 (nindy_fetch_registers): Unpack double regs to host double, then
3486 (nindy_store_registers): Pack extendeds to host double, flip
3487 around by misusing unpack_double, send as target double.
3489 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
3490 zero, as when stopped at the first instruction of a process.
3492 * blockframe.c: Fix filename in comment (param.h => tm.h).
3493 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
3494 * tm-68k.h: Fix typos.
3496 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
3498 Changes from a bringup on the DEC Vax under Ultrix 4.0.
3500 * coredep.c (fetch_core_registers): Pass end-address of register
3501 section to register_addr as expected. Don't call supply_register
3502 if we'd just pass it garbage.
3504 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
3506 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
3508 * target.c (push_target, target_info): Cast enums to int for < or
3511 * stack.c (print_frame_info): Identify source file & line
3512 even if we can't print it.
3514 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
3516 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
3518 Clean up IEEE floating point support.
3520 * ieee-float.h: New file.
3521 * ieee-float.c: Write real routines to convert between host
3522 doubles and various target IEEE extendeds.
3523 * m68k-xdep.c: Eliminate assembler code for extended floats.
3524 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
3525 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
3526 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
3527 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
3528 double_to_ieee_extended.
3529 * i960-tdep.c: Define ext_format_i960.
3530 * m68k-tdep.c: Define ext_format_68881.
3531 * sparc-tdep.c: Define ext_format_sparc, though unused.
3532 * Makefile.dist (HFILES): Add ieee-float.h.
3533 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
3536 Obsolete the "coffstrip" program in favor of using BFD's strip.
3538 * nindy-share/coffstrip.c: Remove file.
3539 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
3540 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
3541 * tconfig/nindy960: Remove reference to coffstrip.o.
3543 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
3545 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3547 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
3548 * dbxread.c: Remove static symfile_bfd.
3549 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
3551 * inftarg.c (child_detach): Pop the child_ops vector if the
3552 detach is successful.
3553 * remote-nindy.c (nindy_create_inferior): Don't push a new
3554 nindy_ops since nindy uses the same one for execution and memory
3556 * core.c (core_ops): Use child_attach and child_create_inferior
3557 rather than default attach and create_inferior functions.
3559 Handle floating point registers in core files.
3561 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
3562 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
3563 This version untested since BFD doesn't yet support sun3 core
3565 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
3566 conventions. Fix comments and style. This version has not
3567 been compiled yet, since we have no HP inhouse.
3568 * core.c (get_core_registers): Look for two sections, ".reg"
3569 and ".reg2", and pass both to fetch_core_registers sequentially.
3571 Revise directory path yet again.
3573 * source.c (forget_cached_source_info): Not static any more.
3574 (init_source_path): New default source path is "$cdir:$cwd".
3575 (dir_command): Handle variable arguments ($cdir, $cwd).
3576 (source_info): Print "Compilation directory" rather than
3577 "Originally compiled in" to remind people of $cdir.
3578 (openp): If the path contains $cwd, use current directory.
3579 (open_source_file): If compilation directory is known, replace
3580 first $cdir in path with the compilation directory.
3581 (print_source_lines): Even if we can't print the lines, set the
3582 current symtab and line for future commands like "info source" or
3583 "breakpoint". Also, error message now contains the file name,
3584 line number, and file access error message.
3585 (_initialize_source): Fix help text to describe changes.
3586 * main.c (cd_command): Forget cached source info when we chdir.
3587 * utils.c (strstr): Add simple implementation.
3589 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
3591 * coffread.c (read_one_sym, init_linetable, init_stringtab):
3592 Byte-swap COFF symbol tables if necessary when reading them in.
3593 Use complain() to replace error message in one spot. Needs
3594 corresponding change in bfd/coff-code.h to make some symbol
3595 swapping routines non-static.
3597 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3599 Merge changes from Eirik Fuller, for UTek.

3607 declarations of errno.
3609 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
3611 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
3612 <rpc/rpc.h> and <rpc/types.h>.
3614 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
3616 * i960-tdep.c (examine_prologue): Add new argument limit,
3617 which stops the scan at the end of the prologue, or at the PC.
3618 This fixes a problem where it walks down into the code for the
3619 user's statements if that code looks like function prologues.
3620 Mark Fox and I have been bouncing this code back and forth, making
3621 small changes to it. Callers changed to match.
3623 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
3625 Cleanup for gdb-3.94 release final:
3627 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
3628 the .c files from vx-share and nindy-share, from the various
3629 macros, since they are not found via ALLDEPFILES.
3630 (SFILES): Add tm-i960.h.
3631 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
3632 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
3634 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
3635 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.

3639 * am29k-tdep.c: Add contribution line.
3640 (examine_prologue): Cache information about function prologues in
3641 the misc-function-vector to avoid lots of references over the
3642 serial line while examining instructions.
3644 * core.c (core_close): New function made from cleanup_core.
3646 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
3647 remote-vx.c, remote.c, target.c, target.h,
3648 Update target_ops vector to add attach, close, and load entries.
3649 Use add_syms_addr_command, not add_file_addr_command, for
3650 add_file. Break out close routine from existing code.
3652 * dbxread.c (really_free_pendings): Don't free pending_blocks;
3653 they are in an obstack.
3654 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
3656 (define_symbol): Add symbol type parameter; change callers;
3657 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
3658 it to influence the symbol class on the i960.
3659 (define_symbol): Swap LOC_CONST's into target byte order.
3661 * exec.c (exec_close): New function.
3662 (exec_file_command): Call it.
3664 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
3665 Fix byte order of frame pointer.
3666 (read_var_value): Result of 0 if var's value can't be found,
3667 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
3668 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
3669 (locate_var_value): Use read_var_value and use its lazy address
3670 as the location of the var's value. Lint.
3672 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
3675 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
3676 obsolete Intel versions in favor of vxgdb versions.
3677 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
3678 code dealing with byte order of values, which Intel did in host byte
3679 order rather than gdb-4's target byte order.
3680 (i960_frame_chain_valid): Move to nindy-tdep.c.
3681 (examine_prologue, skip_prologue, frame_find_saved_regs,
3682 frame_args_address, leafproc_return, saved_pc_after_call,
3683 pop_frame): Add vxgdb versions from Mark Fox.
3684 (examine_prologue, frame_struct_result_address): Add code
3685 to deal with the saved value of G13 (struct return address
3687 (frame_args_address): Modify Mark's version to prefer the
3688 saved value over the current value in the topmost frame.
3689 Cache result in the frame info to avoid performance hair in
3691 (print_fault): Add gdb960 code for printing faults.
3692 (_initialize_i960): Actually call check_host.
3694 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
3695 add stub routines. FIXME, these currently just return zero!
3697 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
3698 (attach_command): Call target_attach, not target_open, now.
3700 * infrun.c (normal_stop): Make global, not static, for vx_attach.
3701 (child_attach): Rename from child_open.
3702 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
3703 don't confuse it with a zero step_resume_break_address.
3705 * inftarg.c (child_detach): Eliminate inferior_pid test.
3706 (child_files_info): Clean up message a bit.
3707 (child_ops): Use child_attach, not child_open, to attach.
3709 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
3710 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
3711 findvar.c to here, since it depends on the contents of the
3712 shadow_contents of breakpoints, but keep if #if 0 since it is
3715 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
3718 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
3719 (ptype_command, display_command): Eliminate have_inferior_p and
3720 have_core_file_p in favor of target_has_stack or
3721 target_has_execution.
3722 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
3723 code for actually finding the values of arguments, though we still
3724 keep track of the maximum stack offset for use in printing unnamed
3725 arguments. Handle missing FRAME_ARGS_ADDRESS.
3727 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
3728 (struct nindy_regs): Define registers passed to/from nindy.
3729 (nindy_fetch_registers, nindy_store-registers): Translate between
3730 nindy and GDB formats for the registers.
3731 (dcache_init): Statically allocate the cache, since it was being
3732 allocated by a malloc that was never freed anyway.
3733 (nindy_create_inferior): Error, not core dump, if no exec file.
3734 (nindy_before_main_loop): Use target_load, not target_add_file.
3736 * remote-vx.c (net_load): Specify large timeout for load
3737 requests. Allow user to break out with INTERRUPT.
3738 (net_break): Remove useless code, clean up. Change callers.
3739 (parse-args, skip_white_space, find_white_space): Clean up arg
3740 parsing to cope with quoted strings.
3741 (net_wait, net_quit): Never call error, just return status.
3742 (vx_read_register, vx_write_register): Cleanup status checking.
3743 #ifdef the code based on which CPU we are using (960 or 68k),
3744 FIXME, this should be completely general but it isn't yet.
3745 (vx_xfer_memory, vx_resume): Cleanup status checking.
3746 (vx_run_files_info): Improve message.
3747 (vx_load_command): Renamed from vx_add_file_command. Allow load
3749 (net_ptrace): Remove unused routine.
3750 (vx_wait): Adopt code from vxgdb960 to cope with broken
3751 connections to target machine and prompt to disconnect. Remove
3752 debug printouts. Map some EVENT_'s to SIGnals.
3753 (add_symbol_stub, vx_open): Print names of object files we found,
3754 and "ok" if we read their symbols OK. Clarify output in general.
3755 (vx_attach, vx_detach, vx_kill): Add these commands.
3756 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
3757 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
3758 "info files" output, and create_inferior, since we already have
3761 * stack.c (frame_info): Replace Frame_unknown with 0.
3762 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
3763 (return_command): Pop until the PC matches as well as the FP,
3764 so it works even if the FP is shared with another function,
3765 as in "frameless" or "leaf" procedures.
3767 * symfile.c (load_command): renamed from add_file_target_command.
3768 (add_syms_addr_command): renamed from add_file_addr_command.
3769 (add_syms_command): Stub to call target_add_syms.
3770 (_initialize_symfile): Change command names and descriptions,
3771 add-file => add-syms, and load from alias to its own command.
3773 * target.c (kill_or_be_killed, maybe_kill_then_attach,
3774 maybe_kill_then_create_inferior): Default for attempts to start
3775 a process, if one is already running, is to ask about killing
3776 it and retry if yes.
3777 (upstack_create_inferior): #if-0 it, strata obsolete it.
3778 (push_target, unpush_target, pop_target): to_close() a target
3779 before unstacking it.
3780 (target_info): Renamed from target_files_info.
3781 (_initialize_targets): Rename "i files" as "i target", accessible
3784 * target.h: Improve comments about the target_ vectored routines.
3786 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
3787 Convert commenting style to standard GNU style.
3788 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
3789 (SKIP_PROLOGUE): No longer a no-op.
3790 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
3791 (*_REGNUM): Sort register numbers.
3792 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
3793 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
3794 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
3795 are now 10 byte extendeds, not 8 byte doubles.
3796 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
3797 for nindy versus vxworks targets. FIXME, this should possibly go
3798 in the target vector.
3799 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
3800 frame_saved_regs and arg pointer with each frame.
3801 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
3802 (FRAME_ARGS_ADDRESS): Use cached result.
3803 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
3804 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
3805 (PRINT_RAMDON_SIGNAL): Call print_fault.
3806 (POP_FRAME): Now works.
3808 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
3809 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
3810 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
3811 (ADDITIONAL_OPTION_HANDLER): use target_load, not
3814 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
3815 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
3817 * valarith.c (value_subscripted_rvalue): Avoid handling
3818 floats and doubles specially; it gave alignment errors. Lint.
3820 * valops.c (value_of_variable, value_of_this): Error if unknown
3823 * valprint.c (print_floating): Bcopy rather than pointer-deref,
3824 to avoid alignment problems.
3825 (value_print): Handle unknown value address.
3826 (cplus_val_print): Two args are ignored; remove them. Change caller.
3827 (val_print): Use unpack_long rather than pointer-deref.
3830 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
3831 to avoid alignment problems.
3832 (value_being_returned): Error if return value unknown.
3833 (set_return_value): Add bogosity warning, FIXME. *
3835 * TODO: A woman's work is never done.
3837 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
3838 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
3839 Add ieee-float.o to OBS.
3840 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
3841 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
3842 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
3844 Changes to generalize the VxWorks RPC protocol slightly, to handle
3845 i960 as well as 68000.
3847 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
3848 * vx-share/reg.h: Produce i960 regs #ifdef I80960
3849 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
3850 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
3851 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
3852 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
3853 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
3854 so they will move in target byte order rather than network
3855 byte order (happens to be the same).
3857 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
3859 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
3861 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
3864 Add contribution lines to various files, showing where they
3867 * breakpoint.c (break_insn, check_break_insn_size,
3868 read_memory_nobpt): Remove to mem-break.c.
3870 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
3873 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
3874 entry has bad register number. This change is not
3875 tested in this release, FIXME.
3877 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
3880 * value.h: Force value's contents field to be aligned to hold
3881 at least a double or a long long (if supported). This avoids
3882 doing bcopy's in and out of the contents field.
3884 (step_1): Avoid coredump under obscure circumstances when we
3887 * symtab.h (misc_info): Add field to misc function vector for
3888 any kind of cached information the target code desires. AMD
3889 29000 uses this to avoid repeating examine_function_prologue's.
3891 * coffread.c: Lint. Remove static symfile, read_section_header.
3892 core.c (have_core_file_p): Lint: remove.
3893 expprint.c (print_subexp): Lint.
3894 infptrace.c, valops.c, valprint.c: lint.
3896 Roll in changes from vxgdb-5.0.1:
3898 * symtab.h: Comment byte order of each address class. Add
3899 LOC_LOCAL_ARG for frame-relative args (960).
3900 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
3901 symtab.c, symmisc.c: ditto.
3903 * infrun.c (init_wait_for_inferior): Clear stop_signal.
3905 * remote.c (remote_resume): Error if resume with a signal.
3907 * symfile.c (prim_record_misc_function): Clear misc_info.
3908 (fill_in_vptr_fieldno): Check stub type of arg.
3910 * valops.c (value_cast): Avoid looking up names of types whose
3911 name we don't know, to prevent coredump. Sun CC produces typedef
3912 rtx and the name of *rtx is zero...
3914 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3916 Roll in changes from final AMD 29000 port (Tiemann).
3918 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
3919 for ../include/a.out.encap.h. This might not work now that BFD
3920 is separately compiled. Instead, BFD support for encap will have
3921 to translate machine type 29k into the right COFF_MAGIC.
3923 * infcmd.c: Remove references to inferior_pid that aren't used
3924 in actual ptrace calls; use target_has_execution, etc.
3925 (have_inferior_p): Remove function.
3926 (program_info): Print target info rather than "process number";
3927 avoid gratuitous messages unless from_tty.
3928 (run_stack_dummy, finish_command): Set proceed_to_finish.
3929 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
3930 main.c: Lint. Lose have_inferior_p().
3931 inferior.h (have_inferior_p): Remove, lint.
3932 (proceed_to_finish): Add flag to ask that all regs be saved
3933 by normal_stop, for the few commands that need it, speeding up
3934 serial I/O. Add comments to stop_registers.
3936 * remote-eb.c: Remove newline from breakpoint message we grep
3937 for. Never time out when running the user program.
3941 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3943 Roll in changes from vxgdb-5.0.1:
3945 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
3946 symbol in its raw form, we are processing an unlinked ".o" file.
3947 See if the target environment has assigned it an address, using
3948 target_lookup_symbol (VxWorks does), and enter it into the symtab
3951 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
3952 68k versions for a simpler version that assumes zero FP at bottom.
3953 Fixes bug of truncated stack reports.
3955 * target.h (target_lookup_symbol): Define this routine's args
3956 and result, finally.
3958 * target.c (nosymbol): Default routine for target_lookup_symbol.
3959 (target_default): Default lookup_symbol and call_function too.
3960 (files_info): Only print has_all_memory warning if a non-dummy
3963 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
3964 vx_convert_from_virtual): If target does not have floating point,
3965 zero register "values", and avoid doing cross-net conversions.
3966 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
3967 (vx_open): Rearrange code that attaches to target and reads
3968 symbols for all loaded modules, to work if some of the modules
3969 are not accessible. Add symbol_stub() and add_symbol_stub()
3970 as callbacks from catch_errors(). Allow connect attempt to be
3971 interrupted painlessly with ^C (FIXME, there are still some bugs
3972 if the interrupt happens during symbol reading.). Print
3973 final message with puts_filtered, since symbol messages are
3978 * main.c (catch_errors): Only print errstring if non-null.
3979 (command_loop): Avoid an ioctl per command to test ISATTY.
3981 * remote-vx.c (net_load): make static; avoid sophomoric msg.
3982 (vx_xfer_memory): Return correct result!
3983 (vx_files_info): Indicate whether target has float or not.
3984 (vx_lookup_symbol): Complain, not error, if target gone.
3985 (vx_open): Print "Connected" msg before disabling immediate-quit.
3986 [FIXME: lookup_symbol and vx_open changes need testing.]
3988 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
3989 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
3990 contributor lines and update copyrights to 1991.
3992 Changes from an attempted H-PUX host port:
3994 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
3995 defines PT_ATTACH and PT_DETACH but not PT_KILL.
3996 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
3997 * remote-vx.c: include <sys/time.h> for HPUX.
3998 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
3999 "core_file_command" routine to BFD regime. May not work yet.
4001 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
4003 * xgdb.c: Replace X10 version with some VJ version.
4004 (FIXME: Its copyright assignment is not on record.)
4005 * xgdb.c: Update include files to X11R4 (Xaw crud).
4006 (xgdb_display_source, create_text_widget): fix call to
4007 get_filename_and_charpos. Rewack source window stuff for X11R4
4008 (gleaned from include files, and "nm's" of binary libraries, since
4009 I had no doc available).
4010 (append_selection, append_selection_word): Disable with FIXME
4011 since R4 changed interface here.
4012 (create_buttons): Add back the old set of buttons.
4013 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
4015 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
4016 Roll VERSION to 3.94 (not yet final though).
4018 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4020 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
4021 obstack_int_grow, obstack_int_grow_fast): Eliminate
4022 cast on left of assignment, which gives MIPS cc fits and is
4025 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
4026 F_ALIAS. Use printf, not fprintf, when not passing a file
4028 (compare_opcodes): Check that identical instructions have
4029 identical opcodes, complain otherwise.
4031 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
4032 was reported by Roland McGrath.
4033 (unimp): Only match if exactly zero instruction. (Roland)
4034 (branches and traps): Generate all variations of these
4035 instructions with macros, based on a single call that defines
4036 each condition name and its binary representation.
4037 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
4039 * valprint.c (val_print_fields): Take, and use, format parameter.
4040 This means that "p/x struct" again prints the elements in the
4041 desired format. Changed callers.
4043 * stack.c (frame_info): Use filtered output, and indicate wrap
4044 points. Remove kludgy formatting designed to avoid line wrap.
4046 * utils.c (wrap_here): If the line is already full (because
4047 we had printed a long indent or long wrapped string), do an
4048 immediate newline-and-indent.
4050 * m68k-pinsn.c (print_insn_arg): Bugfix from
4051 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
4052 instruction is incorrectly disassembled as bkpt #8.
4054 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
4055 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
4056 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
4057 and then will dump core (sometimes). I traced it back to an
4058 uninitialized symfile_name in psymtab_to_symtab.
4059 (const_vol_complaint): Add quotes to message.
4060 (define_symbol): Only believe line number if gcc_compiled.
4061 Avoid allocating symbol if we will not return it.
4063 Add target strata support so that newly established targets go
4064 into their right place in the target stack (e.g. a new exec file
4065 doesn't wipe out the ability to access the running process).
4067 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
4068 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
4069 and initialize it properly in all the targets.
4071 * target.h: Document strata. Change return type of push_target.
4073 * target.c (nomemory): new function for dummy memory access.
4074 (tcomplain): Rename complain, now also used in symfile.c.
4075 (push_target): Push targets within strata. New return value shows
4076 whether new target is on top of stack or not. Always keep dummy
4078 (target_files_info): Ignore dummy target.
4080 * core.c (core_open): Warn user, and skip accessing file, if the
4081 core target is not the topmost target in the stack.
4082 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
4085 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
4086 target_ops, it doesn't belong there since we have no regs there.
4087 Change name of target from machine => memory to clarify.
4089 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
4091 * Freeze version 3.93 for release.
4093 * Makefile.dist: Handle vx-share and nindy-share subdirs
4094 properly when building gdb.tar.Z.
4096 * symtab.c: lint; add no_symtab_msg to consolidate the messages
4097 printed in various places, so I could change just one copy.
4099 * dbxread.c, coffread.c: Change references to bfd->iostream
4100 to cast to FILE *, now that BFD avoids needing types defined
4101 in other header files.
4103 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
4105 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
4106 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
4107 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
4108 (actually gcc -Wall).
4110 * dbxread.c: Remove first_global_sym, last_global_sym, since
4111 they are never referenced.
4113 * defs.h (baud_rate): Declare.
4114 main.c: Define it, and add the -b option to set it.
4116 * gdb-int.texinfo: Add text on how to define a new host or target
4117 architecture, prompted by Per Bothner's questions about MIPS
4120 * gdb.texinfo: Document "complaints". Change doc of -q since
4121 gdb no longer prints the copyright and blurb if you specify a file
4122 name to be debugged (just like Emacs). Add doc for Nindy-specific
4123 command line flags for specifying target serial port and such.
4124 Update copyright to 1991.
4126 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
4127 has taken over for us the job of ripping up executable files. The
4128 crud caused Per Bothner's port to not compile.
4130 * infrun.c (normal_stop): Avoid printing "Program exited
4131 normally" if we are in batch mode. This allows a GDB which
4132 executes a program on a target system, to behave like a Unix
4133 command (input from stdin, output to stdout, no extraneous
4136 * main.c (main): Allow additional machine-dependent command line
4137 options to be specified with the ADDITIONAL_OPTIONS,
4138 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
4139 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
4140 processing to occur just before the main loop with
4141 BEFORE_MAIN_LOOP_HOOK.
4142 (main): If a "core file" argument is specified, and it is not a
4143 core file, try it as a process ID to attach.
4144 (symbol_completion_function): Attempt to cope with
4145 "show screen-" TAB, not very successfully. This needs more work,
4147 (batch_file): New function, returns whether we are reading
4148 commands from an interactive tty on stdin, or from somewhere else.
4149 Called by normal_stop since it doesn't get from_tty passed down
4150 to it like many commands do.
4152 * remote-nindy.c: Handle command line options for nindy
4154 (nindy_before_main_loop): Prompt user for tty name if they
4155 don't specify it before getting to the interactive command loop.
4157 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
4158 and -r command line options. Also add hook before main loop
4159 to make it easy to specify a tty.
4161 * TODO: More things to do, one done.
4163 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
4165 * dbxread.c: Make complaint() calls pass pointer, not struct.
4166 Add complaints about badly formatted C++ type information
4167 (const/volatile indicator, and parse errors resulting in
4168 error_type). Fix C++ virtual member fn comment.
4169 (read_struct_type): Avoid bumping pointer if we got a parse
4170 error; this prevents our walking beyond the end of a string.
4171 Terminate loop on null char as well as semicolon.
4172 (process_one_symbol): Fix the LBRAC fix so that it uses the
4173 last previous SLINE, FUN, or SO record's PC address. C++ debug
4174 symbols did not have SLINE records in a useful order compared
4175 to the LBRAC records.
4176 (define_symbol): Handle "catch" records.
4178 * symtab.c (check_stub_type): Added new complain
4179 `stub_noname_complain' and added a consistency check to
4180 keep the debugger from crashing when finishing from an
4181 exception frame. A real fix will be needed later.
4183 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
4185 * infcmd.c (attach_command): Make global.
4187 * Makefile.dist (REMOTE_OBS): Make these compile by default,
4188 but make them easy to comment out. Perhaps later they should
4189 be enabled by what CPU you configure for? FIXME.
4190 (VERSION): Roll to 3.93.
4191 (pinsn.o): Remove rule for obsolete file.
4192 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
4194 Run down a problem that manifested by printing the wrong function
4195 name in stack traces of read_ofile_symtab. Turned out that the
4196 problem was the SunOS 4.1.1 (and previous) C compiler outputs
4197 the LBRAC symbol with an address in the *data* segment, which
4198 blew our binary search through the blocks.
4200 * dbxread.c: Use the complain() facility consistently to bitch
4201 about problems in the symbol file we are reading.
4202 (finish_block): Add code to check the nesting of the blocks;
4203 complain and Procrust them to fit if wrong.
4204 (make_blockvector): Check the order of the blocks, complain
4205 [but don't cope] if wrong.
4206 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
4207 symbols to be sure their PC value is greater than the last SLINE
4208 (line number) symbol we've seen, complaining and adopting the
4209 SLINE PC value if wrong.
4211 * symfile.h (struct complaint, complaint_root, complain,
4212 clear_complaints): Add.
4213 * symfile.c (complain, complaint_root, clear_complaints): Add
4214 facility to deal with non-fatal complaints and to regularize their
4216 (symbol_file_add): Clear complaint counters to allow new complaints.
4217 (initialize_symfile): Add 'set complaints' and 'show complaints'.
4219 * dbxread.c (dbx_symfile_read): Remember the address and size
4220 of the string table for the main symbol file, so we won't read it
4222 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
4223 to avoid reading the string table yet again. Lint.
4224 (throughout): Improve filtered output, including word wrap.
4225 (read_range_type): Improve Bothner's fix to handle other types too.
4227 * utils.c: Improve line wrap implementation. Handle unlimited
4228 width by making chars_per_line unsigned.
4229 (puts_filtered): New, easy, function.
4231 * defs.h (puts_filtered): add.
4233 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
4234 call the identical sort_symtab_syms() in symfile.c instead.
4236 * expread.y: Suggest the `file' command rather than `symbol-file'.
4238 * command.h (enum var_types): Add zinteger for seroable
4240 * command.c (do_setshow_command): Handle var_zinteger. Restructure
4241 nested if's into a switch.
4243 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
4244 we did not stop because of a breakpoint (it must have been for
4245 some other reason, like a "stepi"), so don't print anything.
4247 * symtab.c: Include <sys/types.h> all the time. Now that BFD
4248 doesn't include <sys/types.h>, old SunOS's require it for
4251 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
4253 A test port of gdb-3.92.6 to the Sony NEWS.
4256 Don't normally link in remote- or vx stuff.
4257 Some of it doesn't compile, and it wastes space for 99% of the users.
4258 Remove reference to no-longer-used HAVE_VPRINTF.
4259 Fixed BFD_DEP typo to BFD_DIR.
4261 Fix cast in arg to bfd_h_getlong.
4262 Make char *prefix be const.
4263 Fix how certain range types are mapped into builtin unsigned int types.
4265 Remove 2 #includes. They cause errors (on Sony, at least),
4266 and aren't needed (they wern't in earlier versions).
4268 print_address_symbolic should never demangle labels
4269 (since it prints *assembler-level* labels).
4271 [This was superseded by the change to printcmd below.]
4274 Add some "volatile" return types to avoid warnings.
4275 If MISSING_VPRINTF add vprintf function and not just macro
4276 (since vprintf is used in printcmd.c).
4278 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
4279 (The latter isn't grokked by some PCC-based compilers.)
4281 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
4283 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
4284 * nindy-share/coffstrip.c
4285 Added some forward declarations (otherwise, gcc complains
4286 about implicit extern redefined as static).
4288 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
4290 Changes inspired by Per Bothner:
4291 * printcmd.c (print_address_symbolic): Take additional parameter
4292 specifying whether to demangle.
4293 (print_address): Pass in asm_demangle to control demangling.
4294 (print_address_demangle): New fn, takes explicit arg to control
4296 * utils.c: Add new vars demangle and asm_demangle, and let them
4298 (fputs_demangled): If !demangle, just print the argument.
4299 (fprint_symbol): If !demangle, just print raw symbol.
4300 * valprint.c (val_print): Call print_address_demangle rather than
4301 print_address, to cause demangling to depend on the global
4302 rather than assembler-level demangling setting.
4303 * WHATS.NEW, gdb.texinfo: Document.
4305 * main.c (show_command): Show all settings if no arg.
4306 (initialize_main): Make "info set" the same as naked "show".
4307 * command.c (cmd_show_list): Handle prefix commands in the
4308 list, and print the name of the setting as well as its English
4309 description and value.
4311 Allow gdb functions to specify where a line should wrap if it
4312 exceeds the size of a terminal line. Use it to make the output
4314 * utils.c (set_screen_width_command): New fn, mallocs a buffer
4315 of the right size when screen width changes.
4316 (set_screensize_command, screensize_info): Remove #if 0'd fns.
4317 (wrap_here): New fn, indicates a point in the output where we
4318 should wrap the line rather than just letting it overflow at a
4320 (fputs_filtered): Implement wrapping.
4321 (n_spaces): New fn, returns a pointer to N spaces.
4322 (print_spaces_filtered): Use n_spaces.
4323 * defs.h (n_spaces): Declare.
4324 * stack.c (print_frame_info): Wrap with 4-space indent after
4325 fn name and before filename and line number.
4326 * printcmd.c (print_frame_args): Wrap with 4-space indent
4327 before each argument name is printed.
4328 * valprint.c (value_print): Wrap with no indentation before
4330 (val_print_fields): Wrap with indentation relative to nesting
4331 level before each field name.
4332 (val_print): Wrap with nesting indentation before array elements.
4333 * command.c (do_setshow_command): Avoid extra newlines,
4334 wrap with 4-space indent around values printed, end with period.
4335 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
4337 * breakpoint.c (breakpoint_1): Implement addressprint for
4338 "info breakpoints" display. Change file name and line number
4339 format to " at file:nnn" rather than " (file line nnn)".
4340 * gdb.texinfo: Document.
4343 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4345 Frozen for gdb-3.92.6 release.
4347 README, WHATS.NEW: Update for 3.92.6 release.
4349 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
4350 coffread.o from configs since it is now built by default.
4351 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
4352 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
4353 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
4354 from configs since it is now built by default.
4356 Makefile.dist: Update for release 3.92.6. Handle files that
4357 have been moved to ../include, ../getopt, or ../bfd. Add
4358 saber.suppress and tests directory. Add config.status to
4359 the release (it will say "none").
4361 coredep.c: Minor formatting fixes.
4363 These changes were made in early December but only checked in now:
4364 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
4365 nindy-share/nindy.c: lint
4366 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
4367 register values coming back from the target; we store values
4368 in target byte order everywhere.
4370 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
4372 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
4374 * valprint.c (cplus_val_print, val_print_fields): New functions,
4375 which print C++ objects. They conspire to avoid printing a
4376 virtual base class more than once, following all the twists and
4377 turns of C++ virtual base rules.
4378 (val_print): Call the above rather than do it by hand.
4380 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
4381 symbol file, not for added files like shared libs. This really
4382 needs to be generalized to a timestamp per file.
4384 * core.c (cleanup_core): Avoid coredump if no core file.
4386 * config.gdb: Accept -host or -target in place of +host or
4389 * coffread.c (find_linenos): Avoid desupported BFD interface
4390 to line numbers. We still read them manually rather than using
4391 BFD's "generic" features.
4393 * gdbrc.tex, threecol.tex: Add GDB reference card and its
4395 Makefile.dist: Add refcard to OTHERS list for creating tar files.
4397 * Makefile.dist: Eliminate use of $< in explicit targets.
4399 * readline/Makefile: Use $< rather than $*.c, which does not
4400 include the VPATH in GNU Make.
4402 * tconfig/i960-bout, tconfig/i960-coff: These are identical
4403 copies of tconfig/i960, added for global configuration
4404 compatability. All i960 versions can read both coff and b.out.
4406 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
4407 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
4410 * TODO: Think of more things to do.
4412 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
4414 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
4415 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
4416 64-bit float conversion.
4418 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
4419 equivalent to sun?os4 so global config works.
4421 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
4423 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
4425 * main.c: Only declare linesize once; declare pagesize not at
4426 all, since it is never used.
4427 (main): Clear newly allocated line before it is used.
4429 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
4431 Further stabilization for the Intel 960.
4433 * Makefile.dist: Parameterize the location of the "include"
4434 and "bfd" directories, as well as "getopt". Add symfile.c.
4435 Link in both dbxread and coffread. Fix up "make depend" to
4436 rewack the locations of include, bfd, and getopt in its output.
4438 * README: Document moving include files, improve some of
4441 * coffread.c: Move common code out to symfile.c. Change
4442 symbol_file_command style interface to use new *_symfile_init
4443 and *_symfile_read interface under BFD. Use BFD internal
4444 info to locate line table, symbols, etc.
4446 * core.c (core_fetch_registers): Rename to get_core_registers
4447 to avoid confusion with fetch_core_registers.
4448 (register_addr): Move to coredep.c, which is already machine
4449 dependent. This leaves core.c pretty clean of dependencies.
4451 * coredep.c (register_addr): Accept this routine from core.c.
4453 * dbxread.c: Move common code (with coffread.c, etc) into new
4454 symfile.c. Each psymtab now contains a pointer to the
4455 format-dependent function that knows how to read it in. Make
4457 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
4458 (process_one_symbol): Add code to complain about a "compiler bug
4459 we muzzle here", if we actually see it.
4461 * eval.c (evaluate_subexp): Insert missing "break" statements
4462 in code that determines whether a variable is an lvalue in
4463 memory, register, or whatever. I detected this via a compiler
4464 bug in which it *almost* mashed out the whole switch statement.
4466 * gdb-int.texinfo: Add minor sections on configuring gdb for
4467 release, and about the README file.
4469 * infcmd.c (registers_info): Fix formatting somewhat. Still
4470 not as pretty as before, but it handles byte swapping.
4472 * remote-nindy.c: If data cache routines are interrupted while
4473 waiting for the remote end, be sure that any uninitialized cache
4474 blocks are on the free list, not on the valid list!
4476 * symfile.h: Flesh out this header file with all the various
4477 routines and variables that have been merged in from dbxread.c
4478 coffread.c, and symtab.c to symfile.c.
4480 * symfile.c: New file, containing code common to dbxread.c,
4481 coffread.c, and some code from symtab.c. All generic code for
4482 reading symbol files should be in here now.
4483 (unrecord_misc_function): Remove unused function.
4485 * symtab.h: Remove file-reading things to symfile.h.
4487 * symtab.c: Remove file-reading things to symfile.c.
4489 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
4490 to decode i960 fault types.
4492 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
4493 target.c: Change type of the "resume" function from int to void,
4494 since its result was never used.
4496 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
4498 * main.c: Replace "stupid" with "caution"; you now "set caution
4501 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
4503 * infcmd.c (do_registers_info): Call val_print to deal with the
4504 byte order of the registers being printed. FIXME, this makes
4505 the formatting of the output uglier.
4507 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
4508 defined, call it for signals the debugger doesn't itself use.
4509 The i960 uses this for more detailed fault information.
4511 * remote.c (remote_open): If arg is null, print help rather than
4514 * sparc-xdep.c (register_valid): Avoid declaring size, since
4515 various modules will think of various sizes depending on the
4516 architecture of their tm-file. FIXME, we need protection against
4517 actually entering one of those modules, which would clobber
4518 storage if not for the target architecture compiled into gdb.
4520 * stack.c (up_command, down_command): Always print the frame
4522 (up_silently_command, down_silently_command): New commands
4525 * i960-pinsn.c (reg), i960-tdep.c: Lint.
4527 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
4528 more parameters than it used to.
4530 * findvar.c (registers): Increase slop to 256 bytes, which should
4531 protect us against even most RISC machines with large register
4533 (locate_var_value): Move declaration inside related ifdef.
4535 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
4536 throughout, to avoid throwing away buffered input from the board.
4537 (nindy_wait): Supply_register takes addr_of_value, not value.
4538 (i960_print_fault): Renamed from i80960_fault.
4539 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
4540 (nindy_store_registers): Avoid regs_changed stuff, just stuff
4542 (nindy_create_inferior): Don't bother to write PC_REGNUM since
4543 we can set the PC in the call to proceed(). Unpush nindy_ops
4544 before pushing it on top, to avoid message to user. Eliminate
4545 commentary from Unix machines that just misleads here.
4546 (reset_command): Fix error message to suggest target command.
4548 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
4550 Release 3.92.5 as frozen.
4552 Stabilize the merged release...with help from lint, Saber C,
4555 Everywhere: Add include files needed to declare return types
4556 of functions called.
4558 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
4560 * breakpoint.h: Add undeclared breakpoint functions, and some
4561 functions for display handling since I couldn't think of a better
4564 * breakpoint.c (insert_breakpoints): Make code for disabling
4565 shared library bkpts more likely to work. It's used when we
4566 rerun a program and stop before the shared library has been
4568 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
4569 cast from pointer, so it squeezes through catch_errors.
4570 (bpstat_stop_status): Fix logic broken some time ago. We now
4571 always create a bpstat if the stop address matches a breakpoint,
4572 even if we don't stop there -- just like the old code used to do
4573 before I got my fingers into it (sigh).
4574 (breakpoint_1): Print "ignore count" after "stop only if"
4575 condition, since that's how it actually works.
4576 (mention): Handle watchpoints as well as breakpoints.
4577 (watch_command): use set_raw_breakpoint and mention to do most
4578 of the work (and initialize all the fields!). Only pass one
4579 arg to parse_c_expression, since that's all it takes.
4581 * command.c (not_just_help_class_command): Rename arg to args
4582 since we ignore "unused argument" warnings on vars named "args".
4583 inflow.c (child_terminal_info): ditto.
4584 infptrace.c (kill_inferior): ditto
4585 main.c (catch_errors, version_info, quit_command, pwd_command,
4586 source_command, dump_me_command, editing_info,
4587 set_history_size_command, set_history, show_history,
4589 stack.c (locals_info): ditto
4590 target.c (target_files_info): ditto
4591 valprint.c (set_input_radix, set_output_radix): ditto
4593 * core.c: Remove old variables for handling core and exec file
4594 sections (data_start, data_end, stack_start, stack_end,
4595 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
4596 text_end, exec_data_start, exec_data_end, text_offset,
4597 exec_data_offset, data_offset, stack_offset). They're
4598 superseded the more general build_section_table and
4600 (get_exec_file): Mention the `file' command.
4601 (read_memory_check): Rename to memory_error, and only call it
4602 in the case of an actual error.
4603 (read_memory, write_memory): call memory_error.
4604 (core_fetch_registers): Register section name is ".reg".
4606 coredep.c: Remove a bunch of crud now that all this file does
4607 is pull the registers out of a core file.
4608 (fetch_core_registers): Rewrite to actually work, I hope.
4610 dbxread.c: Use a.out.gnu.h, not system a.out, now.
4611 Replace index() with strchr(). Remove all the pre-BFD macro
4612 definitions for accessing the symbol file.
4613 (struct dbx_symfile_info): Encapsulate the information that
4614 dbx_symfile_init needs to pass to dbx_symfile_read in this
4617 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
4618 dbx_symfile_discard): Rearrange symbol file reading to divide
4619 the format-specific part from the format-independent part,
4620 leaving the format-independent part such as file name expansion
4621 and opening in symtab.c. This replaces
4622 partial_symbol_file_open and partial_symbol_file_read.
4623 Symbol_file_read, add_file, add_file_target_command,
4624 add_file_addr_command move to symtab.c. Pass an explicit
4625 "mainline" flag for when reading the main symbol table, rather
4626 than relying on the offset address to be zero or nonzero.
4628 (dbx_symfile_read): Don't allow void *'s to be printed as
4630 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
4631 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
4632 macro" debug version really work.
4633 (read_dbx_symtab): Remove unref'd parameter inclink.
4634 Avoid swapping N_SLINE symbols, for speed.
4635 Merge N_TEXT!N_EXT case with the other external symbol
4636 definitions' case. Add comments.
4637 (start_psymtab): Allocate the symfile name in the psymtab on
4638 the psymbol_obstack, rather than using the caller's storage.
4639 (end_psymtab): Only allocate a dependencies list if there are
4641 (psymtab_to_symtab_2): Use BFD when reopening file to read
4642 its symbols for real.
4643 (read_struct_type): Add FIXME comments where it needs work
4645 (read_huge_number): Add FIXME about overflows.
4646 (read_range_type): Add FIXME about comparing a long to 1<<32.
4648 * coffread.c: Minor changes to move things closer to the new
4649 regime with symtab.c and dbxread.c Major work is still needed
4652 * exec.c (exec_file_command): Remove old variables (see core.c
4654 (xfer_memory): If memory transfer is right at the end of a
4655 section, don't lose.
4657 * findvar.c (get_saved_register): If value is in a real
4658 register, LVAL is lval_register, not lval_memory.
4660 frame.h: Declare print_sel_frame and record_selected_frame.
4662 gdb-int.texinfo: New file, for GDB internals documentation.
4663 Very simple, unformatted doc of cleanups is there for now.
4665 gdbcore.h: Remove obsolete variables that described a.out
4666 section addresses and offsets. (See core.c above.)
4667 Declare fetch_core_registers and registers_fetched.
4669 getopt.c: Declare char *alloca(); even on SPARC.
4671 infcmd.c (run_command): Call target_kill rather than
4673 (step_command, next_command, stepi_command, nexti_command):
4674 Declare from_tty parameter even though we don't use it.
4675 (run_stack_dummy): argument BUFFER is a char array, not
4676 a pointer to REGISTER_TYPE.
4677 (finish_command): using_struct_return needed a value *,
4678 not a struct symbol *.
4680 * infptrace.c (child_xfer_memory): To avoid dependency on
4681 where sections are in memory, try PT_WRITE_D and if that fails,
4682 try PT_WRITE_I. Most Unixes don't care which you use.
4684 * infrun.c (step_resume_break_shadow): Change to array to
4685 match other breakpoint shadow storage.
4686 (clear_proceed_status): Pass address of bpstat to
4687 bpstat_clear, not the bpstat itself.
4688 (child_create_inferior): FIXME comment about if the child
4690 (start_inferior): Remove old function.
4691 (child_open): Use target_kill rather than kill_inferior.
4692 (wait_for_inferior): Ditto.
4693 (insert_step_breakpoint, remote_step_breakpoint): Use
4694 new step_resume_break_shadow.
4696 * inftarg.c (child_wait): If all child processes die,
4697 pretend that the one being waited for exited with signal 42.
4699 * main.c (command_line_input): When scanning for comments,
4700 don't coredump on unclosed quotes.
4701 (quit_command): Use target_kill rther than kill_inferior.
4702 (_initialize_main): Rename class_user from "user" to
4705 * printcmd.c (print_command_1): Initialize "fmt" if no format
4706 is specified by the user.
4707 (print_frame_args): Only add to args_printed if we are
4708 actually fetching args from the stack (avoiding undefined
4710 (_initialize_printcmd): Remove bogus \{ from string.
4712 * remote-eb.c (eb_open): Avoid coredump on no argument.
4714 * remote-nindy.c: Bring out of Intel environment into new
4715 target environment. Remove all conditional compilation on
4716 I80960. Massive hacking throughout.
4717 (nindy_xfer_inferior_memory): New routine stolen from
4719 (nindy_create_inferior): New routine pieced together, probably
4720 not quite working yet.
4721 (nindy_ops): New target_ops struct for nindy.
4723 * remote-vx.c: Use write_memory rather than target_write_memory
4724 to get error checking.
4725 (vx_add_file_command, vx_open): Use symbol_file_add rather than
4727 (vx_create_inferior): Use target_terminal_ours...
4729 * signame.c (_initialize_signame): Always initialize, since
4730 we need the table for things other than psignal.
4732 * solib.c (solib_add): Use symbol_file_add, not add_file.
4733 (solib_address): Return boolean result rather than struct
4734 pointer which nobody else knows the type of.
4736 * sparc-tdep.c, valops.c: Use write_memory rather than
4737 target_write_memory, to get error checking.
4739 * stack.c (locals_info, catch_info, args_info,
4740 get_selected_block, frame_command, up_command): Use
4741 target_has_stack, rather than have_inferior_p or
4744 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
4746 * symfile.h: New file, defining the interface between the
4747 generic and object-file-specific symbol reading code.
4749 * symtab.c: Move generic symbol-reading interface to symtab.c,
4750 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
4751 table to map BFD targets to symbol-reading modules in GDB.
4752 Change index to strchr.
4753 (lookup_struct_elt_type): Use error() rather than hand-made
4754 simulations thereof.
4755 (lookup_partial_symbol): Speedup slightly when length == 0.
4756 (symbol_file_add): New function.
4757 (symbol_file_command): Call it.
4758 (symfile_open, symfile_init): New function.
4759 (add_file_target_command, add_file_addr_command): moved from
4762 * target.c (target_command): use target_kill.
4764 * target.h (target_files_info): Don't declare, never called
4767 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
4768 files to determine stack end address.
4770 * valarith.c (value_x_binop, value_x_unop): Change error message
4771 to be more useful. Pass proper argument to value_struct_elt.
4773 * valops.c (value_assign): FIXME comment that long long
4774 bitfields will break here.
4776 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
4777 Update `make saber_gdb' to work better.
4779 * TODO: A woman's work is never done.
4781 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
4782 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
4783 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
4784 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
4785 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
4786 valops.c, valprint.c, exec.c: Lint.
4789 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
4791 Continuing Intel 960 port merge of GDB.
4793 * Makefile.dist: Merge i960 "nindy-share" files. Rename
4794 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
4795 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
4796 Wack over "make depend" so it handles files in subdirectories
4797 vx-share, nindy-share, bfd, and in the current directory.
4799 * blockframe.c (get_prev_frame_info): Remove fatal error
4800 if stack not defined.
4802 * core.c (core_open, core_detach): New functions that handle
4803 the old "core-file" command as "target core" and "detach" instead.
4804 (core_file_command): Call them.
4805 (core_xfer_memory): Use common routine xfer_memory.
4807 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
4808 dbxread now uses bfd for everything but symbol reading itself.
4809 BFD internals are used to drag out the relevant file offsets.
4810 (partial_symbol_file_open): Change args all around for BFD.
4812 * symtab.c: Rename "value" to "val" everywhere, so we can
4814 (symbol_file_command): New command, moved from dbxread.c
4815 and coffread.c. It uses BFD to read the file, then vectors
4816 based on its type, to dbx or coff symbol readers.
4817 * symtab.h: Extern a few vars for symbol_file_command.
4819 * target.h: Breakpoint takes a char * save area, not a char **.
4821 * valprint.c (val_print): When unpacking bitfields, offset
4822 the address in gdb of the value, if it is declared with a shorter
4823 type. Remove the last "runtime kludge test" of host byte order.
4825 * utils.c: Remove old my_bfd_read routine.
4827 * stack.c (frame_info): Use target_has_stack. Print program counter
4828 register's actual name rather than "pc", since it's called the
4829 "ip" (instruction pointer) on the i960 (sigh).
4831 * target.c (target_command): Add command for selecting a target
4832 type and calling its open routine. This is used for initiating
4833 communication with a particular target, in a generic way.
4835 * tm-i960.h: Update for modern gdb. Remove semicolons from
4836 various macros. Handle reading struct return convention, and
4837 error-out attempts to return structs with the "return" command.
4838 Be sure gdb doesn't think we know how to call functions in the

4857 (wait_for_inferior): Clear saved register values before target_wait,
4858 so target_wait can set some of them if convenient.
4860 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
4861 Return success indicator, not void.
4862 (child_xfer_memory): Avoid fetching initial word if we'll

4922 Thu Apr 19 09:54:28 PDT 1990
4923 Add 'reset' command.
4925 Wed Apr 18 09:48:07 PDT 1990
4926 After opening remote tty, wait for 1 second to go by without input
4927 from it before trying to talk to NINDY (fixes problems with the
4928 Heurikon HK80/V960E).
4930 Mon Apr 4 16:33:05 PDT 1990
4931 Some output was not being suppressed in 'batch' mode.
4933 Thu Mar 22 15:31:11 PST 1990

4972 - moved 960-specific routines from i960-pinsn.c to i960-md.c
4973 - made disassembly interface identical to that in gdmp960.
4977 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
4979 * target.h: Allow targets to stack. Add target_has_memory,
4980 _registers, etc. Restructure memory access and "info files"
4981 to walk the target stack.
4982 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
4983 target.c: Change tables to match target.h.
4984 * inflow.c (child_mourn_inferior): pop child_ops.

4988 * remote-eb.c: New memory regime, new info files.
4989 * remote-vx.c: New memory regime, new info files. Now use
4990 separate targets for VxWorks attachment to machine, and
4991 actually running a process under VxWorks, since one has
4992 stack & execution & regs and the other doesn't.
4993 * remote.c: New memory regime, new info files.
4994 * sparc-xdep.c (fetch_core-registers): New memory regime.
4995 * target.c: New routines and support for stacked targets,
4996 new memory regime, new info files regime.

5028 * core.c (core_file_command): Display the frame where the core
5033 * remote-vx.c (target_command): Merge in target command from
5034 targ-vx.c. A few other cleanups.
5036 * TODO, Projects: Lots more stuff to do...
5038 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
5040 Massive changes to wall off the remote-debugging interface
5041 behind a function vector. The port to handle VxWorks targets
5042 is also part of this.
5044 All files: Replace references to renamed functions,
5045 remove references to remote_debugging, remove references to
5046 have_include_file, have_core_file in favor of target_has_stack,
5047 target_has_memory, etc.
5049 * Modularize the breakpoint interface.
5050 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
5051 a breakpoint instruction.
5052 breakpoint.c: struct breakpoint's shadow_contents now sized as
5054 (insert_breakpoints): Vector to target to install breakpoints.
5055 (remove_breakpoints): Vector to target here too.
5056 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
5057 sparc-tdep.c (single_step): Use new breakpoint interface for
5058 the single-step breakpoints.
5059 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
5060 New file, contains routines to insert and remove breakpoints by
5061 reading out the old contents and later replacing them. This is
5062 how ptrace breakpoints work, and many remote systems as well.
5064 * tm-vxworks68.h: New config file, overrides a few things for
5065 Wind River's preferences.
5067 * target.h: New file, for transfer vector used to talk to the
5068 inferior (child, attached, core, exec, remote, etc). All accesses
5069 to the thing being debugged should come through these vectors.
5070 target.c: New file, routines to handle transfer vector.
5071 (various files): Add transfer vectors XXX_ops for the various
5072 targets and pseudo-targets (core files, etc) we support.
5074 * breakpoint.c (bpstat_stop_status): Further explorations of
5075 watchpoints and why things don't work all the time.
5076 (bpstat_alloc): New fn to allocate a bpstat and chain it.
5078 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
5079 the local gdbinit if it doesn't already have it.
5081 * core.c (core_ops): add and install.
5082 Allow core debugging without exec file.
5084 * dbxread.c (free_and_init_header_files): Merge two fns.
5085 (end_symtab): Free named symbol table when a new version comes in.
5086 (read_dbx_symtab): Relocate all kinds of symbols with base
5087 address. First step toward handling different text, data, bss
5089 (add_file_addr_command): Renamed add_file_command.
5090 (add_file_command): Vector to remote handler.
5091 Add "load" as an alias for "add-file" command.
5093 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
5094 non-returning functions.
5096 * exec.c: Add exec_ops, and push it as a target when an exec
5099 * infcmd.c (run_command): Pass executable file name and arg list
5100 separately when starting an inferior. Permit "run" when no exec
5101 file is specified, for VxWorks.
5102 (detach_command): Move to child_detach in inftarg.c.
5104 * inftarg.c: New file. Unix-child-specific routines, and the
5105 child_ops structure.
5107 * inferior.h (registers): Export "registers" as the way for
5108 target dependent register handlers to find gdb's local copy of
5109 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
5110 since it is now used by places that want wait_for_inferior to
5111 handle the grunge but want to see every trap from the inferior.
5113 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
5114 Eliminate remote_debugging hooks in terminal handling.
5116 * infrun.c: Replace start_inferior with child_create_inferior.
5117 Move all the hair of Unix shells and ptrace idiosyncracies into
5118 child_create_inferior, so remote handlers don't have to deal.
5119 Remove running_in_shell. Rename stop_after_attach to
5120 stop_soon_quietly, and use it in a few other places where we want
5121 to just call wait_for_inferior and get control back on the first
5122 trap. trap_expected now never takes a value > 1.
5123 (init_wait_for_inferior): Initialize static vars when a new
5126 main.c (gdbinit): Add new hook for .gdbinit file name, let
5127 it be overridden by config files as GDBINIT_FILENAME.
5128 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
5129 Both of these are used for VxWorks gdb.
5131 mcheck.c: rename include file "gmalloc.c" to avoid problems
5132 with system include file "malloc.c".
5134 param-no-tm.h: New include file, same as param.h but does not
5135 include the default "tm.h" file. This is used in files where
5136 the target is known, e.g. remote-eb.c or sparc-xdep.c.
5138 param.h: Now just a shell that includes tm.h and param-no-tm.h.
5140 remote-vx.c: New file, VxWorks remote debugging support. Uses
5141 RPC routines that are shared with the target system, in directory
5144 remote.c: Vectorize remote interface.
5146 source.c: Globalize source_path, and make an alias "l" for "list"
5147 since we now have the "load" command.
5149 sparc-xdep.c: Use new param-no-tm.h.
5151 symmisc.c (free_named_symtab): Add new function from Wind River.
5152 However, ifdef it out for now while we think about what it should
5155 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
5157 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
5158 non-Unix-children handle this with their own code in the target
5161 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
5162 source and target lists. Add vx-share to default list of include
5163 directories. Add new files to src and target lists: mem-break,
5164 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
5165 ${srcdir} versions of munch and createtags are used.
5167 * valops.c (find_function_addr): Split out of call_function.
5168 (call_function_by_hand): Rename call_function; this function
5169 calls functions in the target by laboriously patching the target
5170 word-by-word with the right stack, args, regs, etc.
5173 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
5175 Handle AMD 29000 a bit better.
5177 * remote-eb.c (readchar): Mask received char log to make it readable.
5178 (remote_start): Pass arguments down to executing program.
5179 Make startaddr unsigned.
5180 infrun.c (start_inferior): Accept args, pass them to
5182 infcmd.c (run_command): Pass args down to start_inferior.
5184 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
5185 the target object file format.
5186 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
5188 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
5189 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
5191 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
5193 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
5194 * TODO: We did a few things, we have more to do though.
5196 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
5197 * inflow.c (inferior_died): Clear deferred stores.
5199 * Debug problems with dummy frames and calls to the inferior.

5202 (sparc_frame_find_saved_regs): Simplify and fix what we find.
5203 (sparc_push_dummy_frame): Simplify and fix what we push.
5204 (sparc_pop_frame): Slightly more hair here, deciding whether
5205 we are restoring a saved PC or returning to a return address in %i7.
5206 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
5208 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
5209 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
5210 * obstack.h (chunkfun): ditto.
5211 * defs.h (xmalloc, xrealloc): ditto
5213 * utils.c (quit): Grab the terminal from the child if necessary.
5215 * inflow.c (term_status_command): Rename to term_info, change
5218 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
5219 (is_delayed_branch): Speed up.
5220 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
5221 Still missing some float ops, and needs testing.
5223 * Support for input and output radixes other than base 10
5224 * defs.h (input_radix, output_radix): Declare.
5225 * expread.y (yyparse, parse_number): Handle changes of input
5226 radix, and ambiguous names-or-numbers in radixes >10.
5227 * printcmd.c (print_scalar_formatted): Print formatted hex
5228 numbers in varying column widths.
5229 * valprint.c (val_print): Use output_format to print scalar ints.
5230 (set_input_radix, set_output_radix, set_radix): Create.
5231 (set_output_radix): Set output_format from output_radix.
5232 (_initialize_valprint): add `set radix' but leave the others off.
5234 * main.c (execute_command): Let stupid questions be turned off.
5235 (_initialize_main): Handle "set stupidity", etc.
5237 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
5238 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
5240 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
5242 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
5243 bfd stuff is still screwed up, but with some manual work, it
5246 * breakpoint.c (bpstat_do_actions): Start over if a command
5247 proceeds the inferior, since the inferior will have stopped and
5248 will need to have its new stop-actions taken care of.
5250 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
5251 compiler fits, simplify it.
5253 * gdb.texinfo (directory command): Doc new dir command.
5254 source.c (directory_command): "dir" now puts things on the front
5255 of the path, moves dups up front, and handles multiple names
5256 on the command line, inserting each one in order. It also
5257 blows away cached line and full_filename info.
5259 * stack.c (backtrace_command): Skip "more stack frames follow"
5262 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
5263 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
5264 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
5265 The only odd one was Gould NP1, which had defined vprintf to
5268 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
5269 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
5270 variable, inspect_it.
5271 valprint.c (print_string, val_print): Use the global inspect_it
5272 to indicate whether to print in Epoch style or normal style.
5274 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
5276 * printcmd.c (call_command): add an alias for the "print" command
5277 which runs expressions and doesn't print the result if void.
5278 (print_command_1): implement it.
5280 * command.c: Remove #if 0'd code. Initialize all the fields
5281 in add_cmd (). Rename do_nothing_command to
5282 not_just_help_class_command, and make it externally visible.
5283 command.h: add user_commands to struct.
5284 * main.c (define_command): Don't overload c->function with a char
5285 string as well as a function pointer.
5287 * eval.c (evaluate_subexp): Reinstall tiemann changes to
5288 calling convention of value_struct_elt () that got dropped in
5291 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
5292 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
5294 * tm-sparc.h (POP_FRAME): replace some constants with defines.
5296 * sparc-xdep.c (store_inferior_registers): defer stores to regs
5297 until a good time (e.g. when we are about to run the child),
5298 saving ptrace calls.
5299 * infrun.c (proceed): handle DO_DEFERRED_STORES.
5300 * tm-sparc.h: define DO_DEFERRED_STORES.
5302 * sparc-xdep.c (store_inferior_registers): when storing float
5303 registers, don't store stack regs too. When storing the SP,
5304 however, DO store the stack regs too. This fixes a bug in which
5305 the dummy frame is not recognized when a call_function finishes,
5306 because its frame pointer (in the stack regs) was never
5308 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
5309 even though we don't know how to read them from an inferior.
5310 valops.c (call_function): Comment about storing SP.
5312 * infrun.c (save_inferior_status): Save away the original bpstat
5313 chain so it can be restored later. Install the copied version for
5314 use by whoever saved the status. It will be blow away by
5315 restore_inferior_status, and the original chain restored. This is
5316 important for people who have pointers into the original.
5318 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
5319 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
5320 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
5323 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
5325 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
5326 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
5327 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
5329 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
5331 * Merge Mike Tiemann's multiple inheritance changes from Sun.
5332 Store the baseclasses in a type struct starting from array element
5333 0 rather than from the unusual array element 1.
5335 dbxread.c: the above.
5336 (virtual_context): Add
5337 Read new debug information about which virtual function table
5338 a virtual function is from, and store it in fn_field.fcontext.
5340 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
5341 TYPE_FN_FIELD_STATIC_P.
5343 symtab.c: the above.
5344 valops.c: the above. Handle pointer casts of object *'s.
5345 (search_struct_method): Add.
5346 (value_struct_elt): First arg is now a pointer to a value, and is
5349 valprint.c: the above.
5350 values.c (value_virtual_fn_field): Add type arg. Handle
5351 offsetting to the proper object when calling virtual fns.
5353 (baseclass_addr): Add valuep arg.
5355 * README: Document the current state of BFD config (missing).
5356 * TODO, ChangeLog, Makefile.dist: Roll version.
5357 * WHATS.NEW: Add summary of changes since 3.5.
5359 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
5361 * dbxread.c (read_struct_type): Clear bit vectors whenever
5363 symtab.c (B_CLRALL): define.
5365 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
5366 using == rather than =. Huh... This fixes the dreaded problem
5367 wherein builtin_type_int becomes TYPE_CODE_FLT.
5369 * core.c (info_files): Show the inferior pid.
5371 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
5372 already knows how to look in the source directory.
5374 * Remove psymtab hair from many places. Remove duplicated code
5375 for searching symbol tables. Hide psymtabs from most places.
5376 Make it fast to get from a psymtab to its symtab.
5378 blockframe.c (blockvector_for_pc): Remove psymtab hair.
5379 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5380 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5381 dbxread.c: export psymtab_to_symtab, make it work if called N times.
5382 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
5383 new symtab completely. New psymtabs get symtab pointer
5384 initialized to zero. Remove MI warning printf.
5385 symtab.h: Comments. Add psymtab to symtab pointer.
5386 (PSYMTAB_TO_SYMTAB): New macro.
5387 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
5388 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
5390 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
5392 (print_frame_info): Avoid special-casing symbols that have not yet
5395 * source.c (open_source_file): Quick path if we have already
5396 located the source file by its full name.
5398 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
5399 find_pc_psymtab. When a name is found in the misc function
5400 vector, search the symbol table for its mangled name, not the
5401 name that the user typed.
5403 * bfd.h: Fix missing comment terminators, make #endifs match.
5405 * valarith.c (value_less): Handle unsigned int comparisons.
5406 Add FIXME about pointer compares, which assume host and target
5407 pointers are the same.
5409 * command.c (do_nothing_command): lint
5410 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
5411 fix comments on debug symbol format for visibility. Actually set
5412 visibility of symbols.
5413 main.c (echo_command): lint; use <readline/history.h>.
5414 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
5415 obstack.h (_obstack_blank): Rearrange pointer math to avoid
5416 pointing past end of allocated memory; saber complains.
5417 obstack.h: Declare the external functions that we use.
5418 valarith.h: use <string.h>
5419 solib.c (solib_add): lint.
5421 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
5423 * main.c (initialize_main): Default info_verbose to off, now that
5424 symbol reading is fast.
5425 (quit_command): Avoid clobbering exec_bfd while quitting.
5427 * Initial BFD (binary file diddling library) merger:
5428 coffread.c: Change AOUTHDR to struct exe_hdr.
5430 core.c: initialize initialized data at compile time.
5431 (core_file_command): Move from coredep.c, convert to bfd.
5432 (xfer_core_file): Convert to bfd.
5433 exec.c (exec_file_command): use bfd routines.
5435 mips-tdep.c: Remove exec_file_command and friends.
5438 * coredep.c: (fetch_core_registers) Convert core_file_command to
5439 fetch_core_registers.
5440 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
5442 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
5443 (my_bfd_read): More bogosity, which I don't think we call.
5444 (program_name): Remove this atrocity asap!
5446 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
5449 values.c: allocate_repeat_value was not clearing the
5450 optimized_out field.
5451 (value_static_field): minor stylistic fix (wrong macro was used).
5452 valops.c (value_struct_elt_for_address): didn't work for C++
5455 * signame.c (_initialize_signame): Initialize signal names once.
5457 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
5458 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
5459 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
5461 * remote-eb.c: Support user-settable baud rates on the serial port.
5463 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
5465 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
5467 * tconfig/sun3os4: Remove warning about native assembler,
5468 since it also occurs in the xconfig file.
5470 * findvar.c (registers): Allocate some slop after `registers'
5471 to prevent stray accesses from trashing the next variable.
5473 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
5474 on the sun-3, by changing the #ifdef from `sun3' (which is not
5475 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
5476 vars, which happened to follow `registers' in the executable.
5478 * readline/history.c (history_search): Heed gcc-2's advice
5479 and parenthesize && inside ||).
5481 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
5482 tm-29k.c: Insert FSF copyright headers.
5484 * remote-eb.c: Better comments.
5486 * Makefile.dist: Update to 3.91.6.
5487 * TODO: note PREPARE_TO_STORE problem.
5489 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
5491 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
5493 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
5495 * infrun.c (wait_for_inferior, at end): Don't set up
5496 prev_* if the inferior no longer exists.
5498 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
5499 CANNOT_EXECUTE_STACK.
5500 valops.c (call_function): Use it.
5502 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
5504 * inferior.h (PC_IN_CALL_DUMMY): New macro.
5505 infrun.c (wait_for_inferior, 2 places): Use it.
5507 * values.c (value_being_returned): Only use
5508 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
5510 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
5511 right thing for remote-eb.c.
5513 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
5514 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
5516 * blockframe.c: Put get_frame_saved_regs inside #if !defined
5517 (FRAME_FIND_SAVED_REGS).
5519 * findvar.c ({fetch,store}_registers): Check for
5520 REMOTE_{FETCH_STORE}_REGISTER macro.
5522 * findvar.c (get_saved_register): Add argument lval and
5523 change meaning of argument addr.
5524 findvar.c: Change calls to get_saved_register to reflect
5525 new calling convention.
5526 valops.c (value_assign): Use get_saved_register instead of
5527 find_saved_register.
5529 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5531 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
5532 an (uninitialized) pointer to one. Use "&" when passing it
5535 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5537 * coffread.c (getfilename): Use DGUX x_offset and x_name if
5540 * coffread.c (symbol_file_command): Put semicolon after
5542 Put safe_to_init_tdesc_context in #if defined (TDESC).
5543 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
5544 coffread.c: #include <sys/stat.h>.
5545 (read_coff_symtab): Typo: in_source_files -> in_source_file.
5546 Add missing ')' in check for "lc%" and friends. Remove
5548 Declare read_one_sym() at top of file.
5549 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
5550 MC68WRMAGIC can have the same value without causing a duplicate
5553 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
5555 * Allow a Makefile to be built without building the
5556 tm and xm file links that screw up builds in subdirectories.
5557 This is done with `config.gdb none', then you can do things
5558 like `make gdb.tar.Z'.
5559 * tconfig/none: Config file for no target system
5560 * xconfig/none: Config file for no host system
5561 * config.gdb: If no TM or XM files are called out by the
5562 host or target file, don't make links for them.
5564 * cplus-dem.c: Add documentation.
5566 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
5567 simple error, so the user's gdb doesn't crash due to some object
5568 file problem (e.g. somebody is rebuilding the file out from under
5571 * printcmd.c (print_address_symbolic): demangle the symbol.
5573 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
5574 Motorola copyrights in it. Make "make gdb.tar.Z" work.
5575 (alldeps.mak): sort and uniq all results from this; duplicates
5576 hose gdb.tar.Z link building. Remove RCS files from
5577 tconfig and xconfig. Add config files for sun386. Add
5578 a few odd files to OTHERS and HFILES.
5580 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
5582 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
5583 Roll version number to 3.91.5. Make lint work in bindir.
5585 * README: Document cross-debugging and new file structure.
5587 * blockframe.c: Lint. Include "value.h" to declare read_register.
5588 (find_pc_partial_function): remove duplicate line.
5590 * command.h: Lint. Declare error_no_arg and dont_repeat.
5592 * tm-news.h: Remove inadvertently duplicated stuff.
5594 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
5595 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
5597 * config.gdb: Allow `config.gdb host target' form. Clean
5598 up previous change that printed bogus messages when you just said
5601 * core.c: #include "command.h" for lint.
5604 * main.c: Remove some casts of enums. Lint.
5611 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
5613 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
5614 read it from memory. This will allow us to save ptrace calls
5615 eventually. Changed caller single_step too.
5617 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
5618 that we aren't going to use, saving many ptrace calls, especially
5619 when watchpointing or single stepping. Use some #define's for
5621 (store_inferior_registers): Ditto.
5622 (core_file_command): Use some #define's for constants.
5624 * tm-sparc.h: Add #define's for some register numbers, so we
5625 can eliminate the use of random constants in sparc-xdep.c.
5627 * stack.c (frame_command, print_frame_info, up_command,
5628 down_command) Remove frame_changed, since it
5629 causes a bug and doesn't seem to do anything useful. In some
5630 places it was used as a flag, in others as a stack level (?).
5632 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
5633 default is to use the portable (vprintf) version rather than the
5635 * xm-news.h (MISSING_VPRINTF): Add.
5637 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
5639 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
5641 * Remove stuff that forces -Bstatic linking of gdb, and warnings
5642 about linking debugged programs -Bstatic in the sun?os4 config
5643 files in tconfig and xconfig subdirectories.
5645 * main.c (main): Remove unreached exit(0) now that we exit
5648 * Create TODO file for online bug list. There are too many
5649 "little" bugs to keep track of on paper.
5651 * Change Projects file to refer to bug-gdb@cygnus.com
5652 rather than kingdon@ai.
5654 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
5656 * Makefile.dist (VERSION): 3.91.4 now.
5658 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
5659 (condense_misc_bunches): Add sanity check that misc_count is
5660 the same as the number of symbols in the bunch.
5662 * coffread.c: rename init_misc_bunches. Pass an argument
5663 to condense_misc_bunches (a zero).
5665 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
5666 every time we are called; don't rely on our caller to do it.
5667 (add_file): Remove call to init_misc_bunches.
5669 * mipsread.c: Only warn, don't error, if unknown symbol types.
5670 This keeps an old gdb from falling on its face if it sees newly
5671 extended symbol info. Rename init_misc_bunches.
5673 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
5675 * Merge in changes from Per Bothner for DECstations and other
5676 MIPS stuff. The rest is Bothner speaking:
5678 The next message is a merger of Alessando Forin's mips port with
5679 mine. I've tried to use my good if biased judgment to get
5680 the best of both. It *does* need testing.
5682 Some of the changes are general, *not* mips-specific.
5685 Didn't believe in little-endian bit order.
5686 There are still inconsistencies about whether flags
5687 like BITS_BIG_ENDIAN are integer (#if ...) or
5688 boolean (#ifdef ...). I tried to paper over them.
5690 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
5691 Moved some misc_function code that was common to
5692 {dbx,coff,mips}read.c to symtab.c.
5693 In the process, I think I cleaned things up a bit.
5694 At the same time, moved obsavestring and obconcat to symtab.c.
5697 Removed obsolete condense_addl_misc_bunches (use
5698 condense_misc_bunches(1) instead).
5701 Needed to include <sys/dir>, at least on DECstations.
5703 valops.c, mips-tdep.c, tm-mips.h:
5704 Added PUSH_ARGUMENTS macro to support funny argument-pushing
5705 conventions (when STACK_ALIGN is insufficient).
5706 Needed on mips, where doubles need 8-byte alignment,
5707 but ints only need 4.
5710 Removed cruft that was not being used.
5711 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
5714 Print $ before register-names (I think that makes things a little
5716 Never print two instructions, even if one delays.
5717 Removed hex-disassemble set_cmd. (This is not mips-specific,
5718 so I think the argument is whether it is generally worthwhile or not.
5719 I'm inclined to think not, given how easy it is to
5720 convert between radixes in gdb.)
5723 This is basically Alessando's code.
5724 It doesn't use obstacks; I changed it to use obstacks
5725 in a few minor places where using malloc causes a
5726 memory leak. (Probably, more places could/should be changed.)
5727 I added record_misc_function where it was missing.
5728 In symbol_file_command and add_file_command, I tried
5729 to make the code consistent with more recent versions.
5730 Minor sylistic changes in parse_procedure.
5731 Make a .gdbinfo. psuedo-symbol point back to the real
5732 procedure symbol (using the isym field).
5735 This is basically from my port, but with a lot of details
5736 and a number of routines merged in from Alessando's version.
5737 I basically used my code "raw" backtrace (use heuristics
5738 from the actual code, rather than symbol table info) - though
5739 the idea is Alessandro's. I feel my code is a little cleaner
5740 here, particularly in being a little more flexible, such as being
5741 able to handle gcc-produced code (which it now can).
5742 It also doesn't do frame caching (which is not useful
5743 more recent gdb versions).
5744 I also used my code for push_/pop_dummy, more or less.
5745 I tried to incorporate AF's code for testing sigtramp
5746 while backtracing; I probably got it wrong.
5747 Added mips_print_register, which tries to scrunch as much
5748 information as possible on a screen...
5749 Removed the skip-prologue set_cmd. As with hex-disassemble (see
5750 under mips-pinsn.c), I don't see anything mips-specific here,
5751 and I don't see it being all that useful anyway.
5754 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
5755 Use more register names (rather than hard-cases numbers).
5757 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
5759 * Hack up 3.90.11 changes:
5761 * Makefile.dist (depend): parameterize $(GCC).
5762 Add solib.c and solib.o.
5763 (readline): Fix vpath for both absolute or relative SRCDIR.
5765 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
5766 Also, let the part I didn't understand at least compile so
5767 I can test the rest. FIXME.
5769 * dbxread.c: Fix thinko using strcmp.
5770 (init_psymbol_list): declare static.
5771 (partial_symbol_file_open): Comment cleanups better, avoid
5772 cleaning up the string table since the caller will do that.
5773 Move the stat for mod time into symbol_file_command, temporarily.
5774 (There should be a mod time for each symbol file, eventually,
5775 to control its rereading. FIXME.)
5777 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
5778 SunOS, which gives error for shared libs otherwise. (From
5779 Schaefer, probably FIXME needs work for portability.)
5781 * solib.c: Move #include "param.h" to work.
5782 Lowercase all the Uppercase Letters In the Messages.
5783 (find_solib): Clean up inferior_so_name for debug printouts.
5784 Allow no argument, to mean all shared libraries.
5786 * symmisc.c: include param.h to get CLEAR_SOLIB.
5788 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)

5834 Take code which is shared between symbol_file_command and
5835 add_file_command and put it into partial_symbol_file_{open,read}.
5836 Split add_file_command into add_file_command and add_file.
5837 Make psymtab_to_symtab read in the string table if the file
5839 Two new parameters to read_dbx_symtab and start_psymtab.
5840 tm-sunos.h: New file.
5842 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)

5859 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
5861 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5863 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
5865 * tm-news.h: Add CALL_DUMMY_*.
5867 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.

5883 copy a makefile into it.
5885 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
5886 consistency with POSIX.
5888 * breakpoint.c (bpstat_stop_status): Disable watchpoint
5889 when we exit its exp_valid_block.
5891 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
5893 * Makefile.dist: Bump version to 3.91.3.
5895 * Clean up handling of breakpoint commands (somewhat).
5896 Prompted by Tiemann bug report "cont 10" doesn't work any more.
5898 inferior.h: Add breakpoint_proceeded to inferior status struct
5899 and globals; save it and restore it.
5900 (clear_breakpoint_commands): Cleanup, remove old #define.
5902 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
5903 (save_inferior_status, restore_inferior_status): handle it also.
5904 (proceed): Remove earlier code that set breakpoint_proceeded.
5905 It is now set only in clear_proceed_status.
5906 (clear_proceed_status): Cleanup, use bpstat_clear rather
5907 than clear_breakpoint_commands. No callers need the stop_bpstat
5908 between clear_proceed_status and proceed.
5910 infcmd.c: Add breakpoint_proceeded definition and comment.
5911 (cont_command, jump_command, signal_command): Move call to
5912 clear_proceed_status right next to call to proceed.
5914 breakpoint.c (bpstat_do_actions): Avoid clobbering our
5915 caller's argument while running down the chain of breakpoints.
5916 Use new variable "breakpoint_proceeded" to determine when
5917 a command that it executes moves the inferior past the
5919 (bpstat_clear): Handle NULL argument.
5920 (bpstat_clear_actions): Avoid useless call to
5921 breakpoint_auto_delete.
5922 (delete_breakpoint): Clean up bpstat's that are pointing to
5923 the deleted breakpoint from the stop_bpstat chain.
5924 (breakpoint_auto_delete): Simplify.
5926 * Clean up handling of EOF, error on stdin, etc. This was
5927 prompted by a network problem that caused gdb to go into an
5928 infinite loop filling up its malloc'd memory.
5930 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
5931 not clear_breakpoints_commands, which is now gone.
5932 (main): If command_loop returns (e.g. from EOF on stdin), do
5933 a quit_command (looping back to command_loop if quit_command
5934 doesn't really quit).
5935 (command_loop): check result from command_line_input and
5936 exit if it returns NULL, rather than passing the NULL to
5938 (gdb_readline): Free malloc'd result space before returning
5941 * utils.c (query): Handle C-d to mean "yes", just as if the
5942 input was not a terminal. Also avoid infinite loop if EOF
5943 occurs in mid-input-line before newline. This allows
5944 query to be used at EOF on stdin with reasonable results.
5946 * infrun.c (proceed): Set breakpoint_proceeded.
5948 * values.c (value_as_long): Avoid infinite recursion for enums.
5949 (_initialize_values): Fix typo in help msg (kingdon).
5951 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
5952 RL_LIB for linking. This allows -lreadline for linking
5953 and nothing for dependencies, once readline is a real library.
5955 * config.gdb: Jim Kingdon: give useful error message if the
5956 host or target type is not recognized.
5958 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
5959 it just defines it. Dumb, but deal with it.
5961 * Jim Kingdon suggests:
5962 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
5964 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
5966 * Makefile.dist (VERSION): Bump version # to 3.91.2.
5968 * Clean up Bothner's changes.
5970 * blockframe.c (clear_pc_function_cache): New function.
5971 * blockframe.c: remake cache_pc_function_* static.
5972 * dbxread.c (symbol_file_command): remove references to
5973 cache_pc_function_* variables.
5974 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
5975 * printcmd.c: Avoid kludging a global variable (addressprint)
5976 to avoid printing the address of a string twice. Instead,
5977 pass the format letter 's' down low enough that it can be seen
5978 to avoid this problem.
5979 (print_formatted): Pass format arg to value_print.
5980 (restore_addressprint): Remove function.
5981 (do_examine): Avoid hacking addressprint, cleanups and such.
5982 (print_frame_args): Add a comment to a Bothner change.
5983 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
5984 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
5985 to wipe out the values cached in blockframe.c.
5986 * symtab.c (find_method): Add comment saying how big you must
5987 allocate to be "big enough". Per being terse again.
5988 * valprint.c (val_print): Handle format letter "s" to print
5989 strings without addresses. Add comment to vtbl printing code
5990 which casts with wild abandon. Rearrange reference-printing
5992 @0xaddr: value (print w/addressprint)
5993 value (print w/~addressprint)
5994 @0xaddr (parameter lists w/addressprint)
5995 or nothing (parameter lists w/o addressprint)
5997 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
5999 * Merge more changes from Per Bothner:
6001 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
6002 annoying) that I tried to improve it. Here are my suggestions.
6004 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
6007 Do automatic de-reference when taking the address of a reference.
6009 Don't deref_ref when printing parameter lists.
6011 More attempts at treating refernences properly.
6013 In val_print, if deref_ref==0, don't print dangling " = ".
6015 Add COERCE_REF macro, which de-references an REF.
6017 * Merge changes from Per Bothner:
6019 * Fixed (Sony news)-specific configuration problems.
6020 * Fixed other problems with using vanilla pcc and libc (enum problems;
6021 assumption that vsprintf exists).
6022 * Some major speed-ups (finc_pc_partial_function now caches a match;
6023 parsing avoids duplicate symbol_lookup calls).
6024 * Changed handling of baseclasses (no longer use baseclasses field
6025 of struct type, use the first n_baseclasses fields instead).
6026 * Various minor changes/fixes, most C++-related.
6029 Cache the most previous match from find_pc_partial_function.
6030 (Save both low and high ends of matching function's pc range.)
6031 This speeds up the loop of infrun.c:wait_for_inferior quite
6032 a bit, and makes step/next commands much zippier.
6034 Added an enum->int cast (otherwise, some compilers barf).
6036 No longer set baseclass offset to 0, since multiple
6037 inheritance now mostly works.
6038 Added a number of casts, to shut up compiler warnings
6039 (after stabs where made enums, not ints).
6040 When discarding a symbol table (in symbol_file_command),
6041 must clear the cache introduced in blockframe.c.
6042 Don't convert $vtbl_ptr_type to vtbl any more.
6043 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
6044 Mask off sign bit emitted by g++ for virtual table offset.
6045 Set voffset to -1 (not 1) for static member functions.
6047 Changed parsing/lexing of names to avoid doing symbol lookup twice
6048 (once when lexing to determine symbol class, once for real).
6049 Now only call symbol_lookup once. Fields of 'this' win especially big.
6051 Subpress printing addr twice in the case of 'x/s addr'.
6053 lookup_basetype_type is no longer used.
6054 Add find_methods as recursive helper function to decode_line_1.
6055 This allows multiple inheritance to work.
6056 Also, once one or more matches has been found, do not look in
6057 base-classes. (Baseclass methods would be overridden, anyway.)
6059 Removed baseclasses array in struct type.
6060 Instead of using baseclasses[i], use fields[i-1].
6061 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
6062 Changed sign convention of voffset (previous was inconsistent).
6064 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
6066 Used to assume existence of vsprintf. Re-written to not need it
6067 if HAVE_VPRINTF is undefined.
6069 typecmp was too pessimistic. Made it less so.
6071 Don't print space after address.
6072 If vtable points to a misc symbol (with 0 offset), print it,
6073 since that indicates the actual class of the object.
6074 Changed ype_print_derivation_info to use new inheritance
6075 scheme (without baseclasses vector).
6077 In value_primitive_field, fixed some bugs left over from previous set of fixes.
6078 Also, changes needed because TYPE_BASECLASSES were removed.
6080 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
6082 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
6085 If there is no path set, and the symbols don't indicate what directory
6086 a file was compiled in, look in the current directory. But either
6087 a path or a known compilation directory will prevent this.
6090 Three independent bug fixes:
6091 * Remove the #if 0 block that breaks some stuff.
6092 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
6093 adapt gdb to either SunOS 4.0.* or 4.1.
6094 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
6097 Instantiate the class T when looking for methods in it. (Tiemann@sun)
6100 (type_print) Demangle the name being printed.
6101 (type_print_base) Handle botched demangling without coredump (tiemann).
6104 (check_stub_method): Document routine.
6105 (tiemann) fix bug for no-arg functions
6106 Avoid clobbering beyond end of malloc'd storage.
6107 Terminate the argument list properly.
6109 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
6111 * Changes merged by John Gilmore:
6114 In breakpoint_1, use new print_address_symbolic instead
6115 of find_pc_partial_function. (This forces use of assembler-level
6116 addresses, and avoids misleading non-mangled source-level names.)
6118 Generalize ansi argument such that -1 means skip arglist totally.
6119 Removed global variable print_ansi_qualifiers (which made
6120 code non-reentrant), in favor of extra explicit arguments
6121 to internal routines.
6123 Add new helper function print_address_symbolic.
6124 Use find_pc_misc_function instead of find_pc_partial_function
6125 (since we want assembler-level symbols here).
6127 Print unknown function as just "f (...)", not "f (...) (...)".
6128 Use new fputs_demangled explicitly.
6130 Fixed a typing violation (problem: value.h cannot be imported
6131 without renaming many variable in this file).
6132 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
6133 decode_line_1: Moved forward some never-reached code.
6134 Made decode_line_2 skip function prologues correctly.
6136 fputs_filtered should not demangle by default.
6137 Add new fputs_demangled to demangle on demand..
6139 Change value_struct_elt to use value_primitive_field (using recursive
6140 utility function search_struct_field). This allows foo.bar to work
6141 for multiple inheritance (so far only for data fields).
6142 Change check_field in the same way (recursive helper function
6143 to support multiple inheritance).
6144 (Note: there are more of these problems that I haven't fixed.
6145 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
6146 value_of_this: 'this' symbol name is now just "this", note "$this".
6148 Don't print static members.
6149 Avoid printing "members of <type>" if there are none.
6150 Simplified type_print_derivation_info by merging duplicate code.
6151 Remove useless blank lines in type_print_base (ptype command).
6153 Added declaration of new routine value_primitive_field.
6155 Added value_primitive_field which is generalized version of
6156 value_field that can handle multiple inheritance (non-zero offsets etc).
6157 Re-implemented value_field to call value_primitive_field.
6159 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
6161 * infcmd.c -- insert else to avoid 'delete env' coredump when you
6162 delete the whole environment. Karl Berry reported the bug.
6163 * source.c - fix openp to avoid //'s in filenames, which
6164 trigger an Emacs bug causing it to not be able to find files
6165 when running gdb in a window.
6166 * dbxread.c - zap the #if 0 that botches the add-file code.
6167 It seems to work a lot better without all the code commented out.
6169 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
6171 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
6174 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
6176 * Makefile - added a ${CFLAGS} to a couple of entries,
6177 added remote-sa.sparc.c
6178 * added remote.sa-sparc.c, a modification of remote.c
6179 which conducts a dialog directly with the SparcStation prom.
6180 * breakpoint.c, infrun.c, sparcdep.c added
6181 remote_insert_breakpoint(), and remote_remove_breakpoint()
6182 to breakpoint.c instead of directly writing breakpoint instructions.
6183 * sparcdep.c on remote_debugging,there is no need
6184 to remove signle step breakpoint instructions.
6185 * main.c added "-epoch" flag and "int epoch_interface" to main.c
6187 * printcmd.c - epoch interface sends lisp expressions to open up
6188 epoch windows on inspection.
6189 * valprint.c - added arrayprint, and addressprint and made adding
6190 format controls easier
6191 * wait.h added a couple of undef's because we were getting
6192 complaints about WSTOPSIG and WTERMSIG begin redefined.
6195 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
6197 * symtab.c (decode_line_1): Add support for handling method stubs
6198 in the type information.
6200 Tue Jul 3 09:39:18 1990 Michael Tiemann (tiemann at masham)
6202 * values.c (baseclass_addr): Run loop from INDEX+1 to
6203 N_BASECLASSES; otherwise, we can still get into a loop.
6204 @@ This should be restructured to use a cleaner search strategy.
6206 Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
6208 * dbxread.c (define_symbol,read_type): Grok GNU C++'s new
6209 abbreviation "Tt" for tags which have the same name as their
6212 Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham)
6214 * symtab.c (list_symbols): add ability to set breakpoints on all
6215 the functions which match a particular regular expression.
6217 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
6219 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
6220 should print ANSI qualifiers (such as `const' and `volatile').
6221 All callers changed to call with ANSI == 1, except from
6222 `check_method_stub', which uses old-style syntax.
6224 * symseg.h (struct fn_field): Remove unneccessary `args' field.
6225 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
6227 * values.c (check_stub_method): New function.
6229 * cplus-dem.c (do_type): Handle "long long" (encoded as 'x').
6231 * dbxread.c (read_type): Handle new GNU C++ method type stubs.
6232 * valprint (type_print_base): Ditto.
6234 * symtab.c (gdb_mangle_typename): New function.
6236 Tue Jun 5 00:18:43 1990 Michael Tiemann (tiemann at gzilla)
6238 * breakpoint.c (catch_command): New function. Provides a
6239 mechanism to set breakpoints based on catch clauses.
6240 (disable_catch): Similar, but disables breakpoints on catch
6242 (delete_catch): Similar, but deleted breakpoints on catch clauses.
6244 Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla)
6246 * blockframe.c (blockvector_for_pc): New function.
6247 * blockframe.c (block_for_pc): Changed to call
6248 `blockvector_for_pc' and get the block itself.
6250 * stack.c (catch_info): New function. Prints info about
6251 exceptions which can be caught in the current frame.
6252 * stack.c (print_frame_label_vars): New function. Similar to
6253 `print_frame_local_vars'.
6254 * stack.c (print_block_frame_labels): Prints out labels that are
6255 defined in this frame. These labels are exceptions that can be
6258 * dbxread.c: Updated to handle N_CATCH symtab types.
6260 Thu May 3 22:10:00 1990 Michael Tiemann (tiemann at teacake)
6262 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
6263 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
6264 when printing the type.
6266 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)
6268 * valprint.c (val_print): Use `baseclass_addr' to access the
6269 baseclasses pointed to via the derived class object at VALADDR.
6271 * values.c (baseclass_addr): New function. Casts derived pointers
6272 to baseclass pointers taking virtual baseclasses and multiple
6273 inheritance into account.
6275 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6279 Fri May 4 12:12:55 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6281 * breakpoint.c (watch_command, bpstat_stop_status): Deal with
6282 exp_valid_block field correctly.
6284 * infrun.c (wait_for_inferior): When checking "don't even think
6285 about breakpoints" if stop_signal == SIGTRAP && trap_expected,
6286 also check step_resume_breakpoint.
6287 Insert breakpoints and continue (not step) if
6288 step_resume_break_address != NULL, even if another_trap.
6289 If trap_expected and we enter sigtramp, then set up a
6291 If trap_expected is set when we hit the step_resume_break,
6293 When calling resume and trap_expected says tell resume to step
6294 (2 places), also check step_resume_break_address.
6296 * infrun.c (wait_for_inferior): Don't set
6297 prev_{pc,sp,func_{start,name}} before calling wait ().
6298 Do set them after exiting loop.

6300 (start_inferior): Initialize them.
6302 Thu May 3 00:15:11 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6304 * infrun.c (wait_for_inferior, after check for trap_expected > 1):
6305 Restore old code which distinguishes between trap_expected and
6306 running_in_shell, just make the latter take any non-TRAP signal,
6309 * values.c (allocate_value): Zero VALUE_OPTIMIZED_OUT flag.
6311 * Makefile.dist (pinsn.o): Use PINSN_CC to compile.
6312 xconfig/3b1 (CC,PINSN_CC): Define.

6331 (printf_command): Add from_tty parameter.
6333 * valprint.c (value_print): Check VALUE_OPTIMIZED_OUT flag.
6335 * value.h: Add optimized_out field and change lazy field to
6336 char. Add macro VALUE_OPTIMIZED_OUT.
6338 * i386-pinsn.c: Change from Eirik Fuller to write to stream directly
6339 instead of stuffing things in buffers (oappend, etc).
6341 * breakpoint.c (bpstat_do_actions): If *BSP is set to NULL by
6342 execute_command, exit both loops.
6344 * Makefile.dist: Don't set TARGET_ARCH. Add .c.o rule.
6346 Tue May 1 17:07:23 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6348 * Makefile.dist (RAPP_OBS, rapp),
6349 rgdb.c, rserial.c, rudp.c, serial.c, udp.c, xdep.h,
6351 m68k-xdep.c, coredep.c: Wrap in #if !defined (RDB).
6353 * valops.c (value_struct_elt), values.c (value_static_field):
6354 Change error messages to remove references to `info methods'.

6359 infrun.c (start_inferior): Add START_INFERIOR_HOOK.
6360 infcmd.c [SHIFT_INST_REGS]: New code.

6368 Mon Apr 23 10:42:21 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6371 findvar.c (get_saved_register): New function.
6372 findvar.c: Rewrite code which called find_saved_register to
6373 call get_saved_register instead.
6375 Sun Apr 22 14:47:51 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6377 * valprint.c (val_print): Change error message printed when
6378 the type has TYPE_FLAG_STUB set.

6391 (store_inferior_registers): Don't call read_register_bytes.
6392 symmetry-xdep.c (store_inferior_registers):
6393 #if 0 out code to fetch registers.

6411 * coffread.c: Define L_LNNO32 if not defined.
6412 (enter_linenos): Use it.
