2
3 Motorola 88000 port without tears, I mean without tdescs.
4
5 * m88k-tdep.c: Blow away all tdesc stuff.
6 Provide functions for all the frame-related macros in
7 tm-delta88.h. Adopt i960-style EXTRA_FRAME_INFO.
8 (examine_prologue, frame_find_saved_regs, skip_prologue): borrow
9 from i960-tdep.c and adapt to the function prologues on the 88k.
10 (read_next_frame_reg): Borrow from mips-tdep.c.
11 FIXME: frame_locals_address should go away.
12
13 * tm-delta88.h: Dump all the tdesc stuff.
14 Macros for all frame-related stuff call fns of same name.
15 Remove duplicated definitions. FP_REGNUM becomes same as
16 SP_REGNUM.
17
18 * xm-88k.h: Eliminate lots of library dependencies, now handled
19 in libiberty. Eliminate KDB nonsupport.
20
21 * doc/gdbint.texinfo: Add rudiments on frames. FIXME, add more.
22
23
24 * stack.c (frame_info): Mark frameless functions.
25 Print locals address (FIXME, remove if same).
26 * blockframe.c: Comment changes, FIXME after.
27 * coffread.c: Even without TDESC, need to zap "@" symbols.
28 Don't register for wierd format names; change the names in BFD.
29
30 * alloca.c, language.c, tdesc.c: Lint.
31 * tdesc.c, tdesc-lib: FIXME: remove these.
32
33 Tue Nov 12 19:30:22 1991 John Gilmore (gnu at cygnus.com)
34
35 * Makefile.in: Add tdesc library support. Fixups to lint,
36 copying.c rules.
37
38 Tue Nov 12 13:43:26 1991 Per Bothner (bothner at cygnus.com)
39
40 * symtab.c (decode_line_1): Remove spurious call to operator_chars.
41
42 Allow setting breakpoints on C++ destructors.
43 * valops.c (destructor_name_p): Don't check TYPE_HAS_DESTRUCTOR,
44 since it lies. Rely on callers to catch missing destructors.
45 * symtab.c (decode_line_1): For example (see above), here.
46 * buildsym.c, symtab.h: Remove TYPE_FLAGS_HAS{CON,DE}STRUCTOR
47 flags since they are no longer used.
48
49 Fixes to support C++ methods with functional parameters.
50 * c-exp.y (func_mod rule): Allow (and ignore) list of parameter
51 types in a function type.
52 * eval.c (parse_and_eval_type), value.h: New function,
53 parse_and_eval_type, is based on old code from check_stub_method.
54 But don't actually evaluate the cast, since that calls
55 value_cast(), whcih may fail. Just extract the type
56 from the parsed expression.
57 * values.c (check_stub_method): While looping through the
58 arguments, adjust depth *after* parameter has been handled.
59 Replace call and setup of parse_and_eval with new function
60 parse_and_eval_type.
61
62 Tue Nov 12 09:40:07 1991 Fred Fish (fnf at cygnus.com)
63
64 * utils.c, rem-multi.shar: Remove fixed arg count version of
65 concat().
66
67 * altos-xdep.c, arm-xdep.c, coffread.c, command.c, convex-xdep.c,
68 core.c, dwarfread.c, gould-xdep.c, infcmd.c, language.c,
69 m88k-xdep.c, main.c, printcmd.c, pyr-xdep.c, source.c,
70 sun386-xdep.c, symm-xdep.c, umax-xdep.c, values.c, xcoffread.c:
71 Change all instances of use of fixed args concat() to variable
72 args concat() now located in libiberty.
73
74 Tue Nov 12 07:23:46 1991 John Gilmore (gnu at cygnus.com)
75
76 * Makefile.in: Add xcoffread.c, xcoffexec.c.

79 * buildsym.c: Add hooks for xcoffread.c.
80 * rs6000-pinsn.c, rs6000-tdep.c, rs6000-xdep.c, tm-rs6000.h,
81 xm-rs6000.h, rs6k-opcode.def, rs6k-opcode.h: New files.
82 * xcoffexec.c: New file for handling AIX shared libraries.
83
84 Mon Nov 11 19:14:31 1991 Fred Fish (fnf at cygnus.com)
85
86 * core.c: Minor rewording of message to user containing name of
87 (and possibly arguments to) the program that generated a core
88 file.
89
90 * elfread.c: Remove the register_addr() stub now that it is no
91 longer needed.
92
93 * procfs.c: Move misplaced #endif for ATTACH_DETACH. Add new
94 fetch_core_registers() function for core file support.
95
96 Sat Nov 9 13:37:57 1991 Fred Fish (fnf at cygnus.com)
97
98 * dwarfread.c (dwarf_psymtab_to_symtab): Remove leftover call
99 to do_cleanups() which resulted from a previous change.
100
101 * elfread.c: Re-enable compilation of register_addr() stub
102 whenever it is not supplied by coredep.c
103
104 Sat Nov 9 00:40:32 1991 John Gilmore (gnu at cygnus.com)
105
106 Add tracking of object files (that contain symbols) to gdb.
107 This includes a "struct objfile" that owns symtabs and psymtabs
108 that were read in from that binary file.
109
110 * symfile.h: Add struct objfile. Add pointer to the objfile
111 into the struct sym_fns.
112 Replace global `symfile' and `symfile_mtime' with
113 `symfile_objfile'. Add global object_files chain.
114

116 (sort_misc_function_vector): Add.
117 (syms_from_objfile): Was syms_from_bfd.
118 (symfile_open): Now returns objfile.
119 (allocate_objfile): New.
120 (free_objfile): New, replacing free_all_.*symtabs.
121 (symfile_init): Takes objfile arg, puts it in sym_fns result.
122 (reread_symbols): Searches whole chain of objfiles.
123 (allocate_symtab): Takes objfile as new parameter, chains them.
124 Handle INIT_EXTRA_SYMTAB_INFO.
125 (free_all_psymtabs, free_all_symtabs): Move here from symmisc.c.
126
127 * dbxread.c: Make more errors into complaints.
128 (push_subfile, pop_subfile): Move to buildsym.c.
129 (dbx_symfile_read, dbx_symfile_init, fill_symbuf, read_dbx_symtab,
130 start_psymtab, psymtab_to_symtab_1, read_ofile_symtab,
131 dbx_psymtab_to_symtab, ): Use bfd ops, don't use file descriptor.
132 Pass objfile. Change callers.
133 (fill_symbuf, SWAP_SYMBOL): Take bfd as arg.
134 (read_dbx_symtab): Just wipe out new symbols, not all, on error.
135 (end_psymtab): Blow away psymtab if empty.
136 (process_symbol_pair): Swallow into read_ofile_symtab.
137 (process_one_symbol): Use push_context and pop_context.
138 (virtual_context): Delete #if 0'd obsolete stuff.
139
140 * buildsym.c (end_symtab): Pass objfile.
141 (dbx_lookup_type): Handle null typevector.
142 (dbx_alloc_type): Check file number, not sym number, for -1.
143 (find_symbol_in_list): Add for xcoffread.
144 (start_symtab): Default typevector is empty. Keep reusing same
145 context_stack.
146 (end_symtab): Take objfile argument and pass it to
147 allocate_symtab. Don't make a symtab if no blocks or symbols.
148 Handle empty typevector.
149 (push_context): New function for context stack nesting.
150 (read_type): Mark FIXME where we need to reintroduce type smashing.
151
152 * buildsym.h (pop_context): Macro, paired with push_context.
153 (subfile_stack): Move here from dbxread.c.
154
155 * coffread.c (end_symtab, read_coff_symtab): Take and use objfile arg.
156 (read_coff_symtab): Cleanup by freeing objfile, not all symtabs.
157
158 * mipsread.c (read_mips_symtab, parse_partial_symbols, parse_fdr,
159 new_psymtab, new_symtab): Take and use objfile arg.
160
161 * dwarfread.c (scan_compilation_units, start_psymtab,
162 process_dies, end_symtab, dwarf_build_psymtabs,
163 read_lexical_block_scope, read_func_scope, read_file_scope): Take
164 and use objfile argument.
165 (psymtab_to_symtab_1, read_ofile_symtab): Don't take or use file
166 descriptor. Use BFD internal functions instead.
167 (end_symtab): Call global allocate_symtab.
168
169 * elfread.c, target.c: Minor changes to accommodate objfiles.
170 * symtab.h: partial_symbol_table has no symfile_name member now.
171 (fn_fieldlists voffset): avoid non-int bitfield.
172 (struct symtab): Add objfile * and objfile_chain * of symtabs.
173 (struct partial_symtab): Add objfile * and objfile_chain * of
174 psymtabs. Remove symfile_name.
175
176 * symmisc.c: Lose free_all_symtabs, free_all_psymtabs.
177 (printsyms_command): Rename from print_symtabs. Add selective
178 listing if 2nd argument given. Print objfile info.
179 (printpsyms_command): Rename from print_partial_symtabs. Ditto all.
180 (printobjfiles_command): New; prints objfiles lists, and checks
181 for consistency of symtab, psymtab, and objfile lists.
182
183 * symfile.h, symfile.c, symtab.h: Lint
184
185 Fri Nov 8 23:38:48 1991 John Gilmore (gnu at cygnus.com)
186
187 * command.c: Include param.h.
188 * defs.h (warning_setup, warning): Declare.
189 * expprint.c (print_subexp, UNOP_MEMVAL case): Lint.
190 * inflow.c (new_tty): Use USE_O_NOCTTY #define.
191 * language.c, printcmd.c (print_scalar_formatted), signame.c,
192 stack.c: lint.
193
194 Thu Nov 7 18:26:15 1991 Steve Chamberlain (sac at rtl.cygnus.com)
195
196 * Makefile.in: link with libiberty after libreadline, since
197 readline might want something in libiberty.
198 * m88k-xdep.c: Fixed the register offsets in the ptrace_user
199 struct for BCS 88k machines.
200 * xm-m88k.h: don't define USIZE if already defined.
201 * configure.in: Added delta88 target.
202
203 Thu Nov 7 04:51:19 1991 John Gilmore (gnu at cygnus.com)
204
205 * am29k-pinsn.c, am29k-opcode.h: Fix decoding of mtacc, dmac, fmac.
206
207 * tm-*.h: Remove READ_DBX_FORMAT, COFF_FORMAT, and
208 READ_MIPS_FORMAT, which have been unused since BFD. Still
209 remaining is COFF_NO_LONG_FILE_NAMES.
210 * tm-sun3.h, tm-altos.h: Remove detritus accidentally left from
211 function calling code moved to m68k-tdep.c.
212
213 Wed Nov 6 17:21:59 1991 John Gilmore (gnu at cygnus.com)
214
215 * coffread.c: Eliminate c_nsyms in favor of c_naux.
216 Complain if no auxents on .bf and .ef FCN symbols, and assume
217 lots of line numbers.
218 (init_linenos, enter_linenos): Use a sentinel at the end of the
219 read-in linenos, to make for a fast, safe loop-end test.
220
221 Wed Nov 6 02:54:08 1991 Steve Chamberlain (sac at cygnus.com)
222
223 * coffread.c (read_coff_symtab): coffread used to rely on the
224 x_sym.x_misc.x_lnsz.x_lnno field giving the # of linnos in a
225 function. Two of the formats I'm using (29k and 88k) don't seem to
226 set it. Ths patch to fcn_last_line and (enter_linenos) is an
227 attempt to use the actual size of the linno table in the file to set
228 the number of linenos to process.
229
230 Tue Nov 5 22:47:46 1991 Steve Chamberlain (sac at cygnus.com)
231
232 * Makefile.in: put a - infront of the mv y.tab.c c-exp.tab.c and
233 mv y.tab.c m2-exp.tab.c, so that if bison is used, and the files
234 are created in place, so the mv fails, then the make continues.
235
236 Tue Nov 5 16:47:47 1991 Per Bothner (bothner at cygnus.com)
237
238 Add C++ as a separate language.
239 * defs.h (enum language): Add language_cplus.
240 * dwarfread.c (end_symtab): Support language_cplus.
241 * c-exp.y: Add new struct language_defn cplus_language_defn.
242 Don't set c to be the default language (see main.c).
243 * c-exp.y (yylex): Only look for field of this if
244 language is C++. (First difference from C!)
245 * language.c: Add case branches for C++ (currently, all
246 the same as C). Also, add c++ to "usage" note for "set lang".
247 * valprint.c (typedef_print). Add case branches for C++.
248 * main.c (main): New way to set initial language: Look at
249 file extension of psymtab containing main(). (Same as we
250 do for symtabs, but avoid loading the symtab yet.)
251 * symtab.c: New routine find_main_psymtab(), used by main()
252 to set initial language.
253 * symfile.c (allocate_symtab): Move code for mapping file
254 extensions-> languages to new deduce_language_from_filename().
255
256 Fix a C++ problem when looking for methods in super-classes.
257 There was confusion between base and derived types.
258 * valops.c (value_fn_field): Change function interface.
259 * values.c: Use new value_fn_field interface.
260
261 Mon Nov 4 10:49:33 1991 Per Bothner (bothner at cygnus.com)
262
263 * infrun.c: Fixed typo in comment.
264 * utils.c: All the v*fprintf emulation is now in libiberty,
265 so we can get rid of some junk.
266 * xm-sun3os4.h, xm-sun4os4.h, xconfig/decstation, xconfig/i386sco,
267 xconfig/sun3os4, xconfig/sun4os4: Don`t need HAVE_STRSTR any more.
268 * m68k-pinsn.c (print_insn_arg): Support BB/BW/BL
269 type operands, as used by branch instructions.
270 * gmalloc.c: Fix prototype of memcpy.
271 * elfread.c: Comment out register_addr, since it conflicts
272 with the one in coredep.c.
273 * buildsym.h: Remove extern declarations of two functions
274 that are really static in buildsym.c.
275 * tm-mips.h: Add symbolic names for more registers.
276 * mips-xdep.c (store_inferior_registers): Use new register names.
277 * xm-mips.h: Simplify REGISTER_U_ADDR, since it is now
278 only used for core files, not ptrace. Therefore,
279 the KERNEL_U_ADDR hack is no longer needed.
280 The mapping to ptrace number is now in in mips-xdep.c.
281 * mips-xdep.c: Define REGISTER_PTRACE_ADDR (using the
282 mapping from the old REGISTER_U_ADDR), and use it
283 in {fetch,store}_inferior_registers.
284 * mipsread.c: Rename #include ecoff.h to new name coff-mips.h.
285 * mips-tdep.c (mips_push_dummy_frame, mips_pop_frame):
286 Save/restore FP regs correctly (?).
287 * dbxread.c: Remove duplicate define_symbol and type_synonym_name
288 (these had been previously moved to buildsym.c).
289 Hence, define_symbol becomes extern instead of static.
290 * buildsym.c (read_struct_type): Comment out bogus handling
291 of C++ operator methods. Minor hacking of reading of class
292 contexts. Make define_symbol non-static, so dbxread.c can call it.
293
294 Fri Nov 1 11:05:47 1991 John Gilmore (gnu at cygnus.com)
295
296 * mipsread.c (read_mips_symtab, read_the_mips_symtab): Use real
297 filename with error messages.
298 * stack.c (frame_select_command): Rename to select_frame_command
299 to avoid "fr" and "fra" having nonunique completions.
300 * symfile.c (sort_symtab_syms): Ignore sort of zero symtab *.
301 (symfile_init): Print file format name when unable to handle it.
302 (free_named_symtabs): Use BLOCKVECTOR rather than obsolete BLOCKLIST.
303 * symmisc.c (free_symtab): Only free linetable if nonzero.
304 * symtab.h: Remove obsolete BLOCKLIST macros.
305
306 Thu Oct 31 18:12:43 1991 Stu Grossman (grossman at cygnus.com)
307
308 * infrun.c (wait_for_inferior): another stepi/nexti fix. Ensure
309 that stop_step is 1 at bottom of main loop. I don't know why this
310 needs to be done, but it helps me sleep better at night.
311
312 Sun Oct 27 18:18:39 1991 Stu Grossman (grossman at cygnus.com)
313
314 * main.c (initialize_history): Read history after reading all
315 init files.
316
317 Sun Oct 27 14:09:25 1991 John Gilmore (gnu at cygnus.com)
318
319 * buildsym.c: Break out initial malloc sizes.
320 (record_line): Record directly in a subfile. Alloc on demand.
321 (compare_line_numbers): Add from xcoffread.c.
322 (end_symtab): New params say whether to sort pendings and
323 linetable. Patch block stabs if defined. Shrink linetable before
324 allocating the symtab.
325 * buildsym.h: Delete line_vector* and prev_line_number. Add
326 global_stabs and file_stabs for xcoffread.
327 * dbxread.c (start_subfile): Move to buildsym. Change above calls.
328 * symtab.h: LINETABLE(symtab) can now be null. Zap LINELIST.
329 * symmisc.c, symtab.c: Cope with null LINETABLEs.
330
331 * blockframe.c: Pass fromleaf to INIT_EXTRA_FRAME_INFO.
332 * tm-29k.h, tm-88k.h, tm-i960.h, tm-irix3.h, tm-mips.h, tm-pyr.h,
333 tm-sparc.h: Accept fromleaf parameter.
334 * c-exp.y (yyerror): Pass error message if given.
335 * configure.in: Add rs6000 host and target.
336 * inflow.c (new_tty): O_NOCTTY kludge for RS/6000.
337 * symfile.h (entry_point): Add.
338
339 Sat Oct 26 00:16:32 1991 John Gilmore (gnu at cygus.com)
340
341 * buildsym.c: New file. Breaks out symbol-table-building routines
342 from dbxread.c, so they can be shared with xcoffread.c.
343 * buildsym.h: New file. Declarations for buildsym.c users.
344 * dbxread.c: Remove large chunks into buildsym.c.
345 * Makefile.in: Add buildsym.c and buildsym.h.
346
347 * symfile.c (syms_from_bfd): New routine.
348 (add_symbol_file): Call it to do the real work.
349 (syms_from_bfd): Initialize entry_point before calling symfile_init.
350 * symtab.h, symfile.c, coffread.c, mipsread.c, dwarfread.c:
351 Avoid declaring or setting entry_point (symfile.h & symfile.c cope).
352
353 Fri Oct 25 18:59:32 1991 Per Bothner (bothner at cygnus.com)
354
355 Various fixes to improve g++ debugging.
356 * symtab.h: Add is_const and is_volatile flags for each method.
357 These are bit fields - take their space from voffset,
358 which shrinks to 30 bits. Since voffset is now a bitfield,
359 make it unsigned for portability. This changes its interpretation
360 slightly: Static methods now have voffset 1 instead of -1,
361 and virtual offsets start at 2, not 1.
362 * symtab.c: Renamed gdb_mangle_typename to gdb_mangle_name,
363 since it now returns an entire magled method name, not just
364 the type part. This avoids some duplication.
365 It also allows us to correctly mangle const and volatile
366 methods (using the new is_const and is_volatile bit fields
367 mentioned above).
368 * valprint.c (type_print_base), values.c (check_stub_method):
369 Simplify by using new gdb_mangle_name.
370 * values.c (value_headof): Fix to correctly handle single
371 inheritance (actually two fixes, either of which suffices).
372 * dbxread.c (read_struct_type): Handle const and volatile
373 method specifiers.
374 * dbxread.c (read_struct_type): Yet one more place where
375 we must handle '\\' continuations.
376 * valprint.c (vtbl_ptr_name): Add final '\0'.
377
378 Fri Oct 25 16:06:38 1991 Stu Grossman (grossman at cygnus.com)
379
380 * tm-sparc.h, tm-68k.h (EXTRACT_RETURN_VALUE): fix output of
381 short return values for sparc and 68k. Patch from Paul Eggert.
382
383 * coffread.c, coredep.c, i386-xdep.c: install patches for
384 SysV/386 3.2 from Mauro DePalma.
385
386 Fri Oct 25 02:02:13 1991 John Gilmore (gnu at cygnus.com)
387
388 * core.c (core_file_info), exec.c (exec_file_info): Print file
389 type. Use printf_filtered.
390
391 * valops.c (value_fetch_lazy): Avoid 0-length fetches.
392
393 Thu Oct 24 23:06:40 1991 Fred Fish (fnf at cygnus.com)
394
395 * dwarfread.c: Add casts to remove compiler warnings.
396
397 * tm-3b1.h, tm-68k.h, tm-altos.h, tm-amix.h, tm-hp300bsd.h,
398 tm-hp300hpux.h, tm-isi.h, tm-news.h, tm-pn.h, tm-sun2.h,
399 tm-sun3.h: Remove locally duplicated code for calling functions
400 in the inferior. The only differences were in the specific trap
401 vectors used and whether or not an fpu was present. These are
402 now handled by appropriate definitions of BPT_VECTOR and
403 HAVE_68881 respectively. Other minor obvious cleanups.
404
405 * valops.c: Correct a minor misspelling.
406
407 * utils.c: Remove local BSD/USG hacks that are now in libiberty.
408
409 * dwarfread.c: Remove prototype for dwarfwarn. Does not work
410 with <varargs.h>.
411
412 Thu Oct 24 09:33:44 1991 John Gilmore (gnu at cygnus.com)
413
414 * stack.c (frame_command): Always print. Use new
415 frame_select_command to select a frame without printing.
416
417 * dwarfread.c: Use <varargs.h>, since <stdarg.h> is not portable.
418
419 Thu Oct 24 01:32:51 1991 Fred Fish (fnf at cygnus.com)
420
421 * dwarfread.c: New file for DWARF debugging format support.
422
423 * elfread.c: New file for ELF object file format support.
424
425 * procfs.c: New file for SVR4 /proc (process file system) support.
426
427 * tm-amix.h, xm-amix.h, tconfig/amix, xconfig/amix: New files for
428 Amiga UNIX support.
429
430 * xm-svr4.h, tm-svr4.h: New files for SVR4 support.
431
432 * xm-m68k.h: New file for host machines with m68k cpu.
433
434 * Makefile.in: Add elfread.c and dwarfread.c to SFILES_MAINDIR.
435 Add elfread.o and dwarfread.o to OBS.
436
437 * symfile.h: Add "elf" to list of supported formats in comment.
438
439 * c-exp.y, defs.h, symtab.h, valprint.c: Add three new builtin
440 types to gdb, builtin_type_long_double, builtin_type_complex, and
441 builtin_type_double_complex. Add and use new TARGET_SHORT_BIT,
442 TARGET_INT_BIT, TARGET_LONG_BIT, TARGET_FLOAT_BIT,
443 TARGET_DOUBLE_BIT, TARGET_LONG_DOUBLE_BIT, TARGET_COMPLEX_BIT, and
444 TARGET_DOUBLE_COMPLEX_BIT, as the sizes in bits of the indicated
445 types on the target machine (ala the existing TARGET_LONG_LONG_BIT).
446
447 * infrun.c: When using SVR4 /proc interface instead of ptrace(),
448 call proc_set_exec_trap() to setup child to stop at first instruction.
449
450 * inftarg.c: When using SVR4 /proc interface, call proc_wait()
451 rather than wait().
452
453 * m68k-tdep.c: Add new routines supply_gregset(), fill_gregset(),
454 supply_fpregset(), and fill_fpregset(), which are machine
455 dependent support routines for SVR4 /proc interface.
456
457 * utils.c: Add warning_setup() and warning(). Warning() behaves
458 the same as error() except that it returns normally rather than
459 jumping back to command level. Modules that don't want to call
460 warning() for some reason, but want to produce their own warnings,
461 can call warning_setup() to ensure compatibility with the way
462 warning() and error() deal with the terminal.
463
464 * symtab.c: Make internal errors produce more useful messages.
465
466 * tm-68k.h: Move code that is duplicated in almost every single
467 m68k based machine's configuration files to this common file.
468 Duplications in the configuration files still need to be removed
469 (FIXME).
470
471 * infrun.c (child_create_inferior): System V versions must call
472 setpgrp() with no arguments, to comply with prototyping typically
473 in <unistd.h>.
474
475 * munch: Add support for SVR4 style nm output.
476
477 * dbxread.c, mipsread.c symmisc.c, symtab.c: Remove the object
478 file specific fields from the partial symbol table structure and
479 replace them with a pointer to private data for each different
480 flavor of object file reader to initialize appropriately.
481
482 Wed Oct 23 09:38:20 1991 John Gilmore (gnu at cygnus.com)
483
484 * xconfig/sun[34]os4: Add note about strstr botch on sunos4.0.3c
485 and previous.
486
487 * mipsread.c (fixup_undef_type): New function. If a struct /
488 union / enum is defined in a header file but nowhere else used,
489 (by typedefing, pointer referencing or declaration) the mipsread code
490 builds the complete tree for the structure but leaves its code as
491 TYPE_CODE_UNDEF as it doesn't know what kind of aggregate it is.
492 Guess its type based on the details of the members.
493
494 Tue Oct 22 18:04:32 1991 Stu Grossman (grossman at cygnus.com)
495
496 * infrun.c (wait_for_inferior): Check return value from
497 find_pc_line.
498
499 Mon Oct 21 17:47:03 1991 Stu Grossman (grossman at cygnus.com)
500
501 * infrun.c (wait_for_inferior): fix stepi/nexti that was broken
502 by my last edit to this routine.
503
504 Mon Oct 21 14:27:43 1991 John Gilmore (gnu at cygnus.com)
505
506 * tm-sun3.h (FIX_CALL_DUMMY): problem with cross debugging.
507 FIX_CALL_DUMMY does unaligned accesses and/or forgets to byte swap
508 the values before putting them into the dummy code. (From Peter
509 Schauer)
510
511 Mon Oct 21 10:04:39 1991 Steve Chamberlain (steve at rtl.cygnus.com)
512
513 * configure.in: added ebmon target.
514

563 exact match.
564 (echo_command): Use printf_filtered, and force output out.
565
566 * dbxread.c (read_enum_type): Avoid Modula-2 kludge that breaks C
567 programs.

571 dec3100 to decstation.
572
573 Mon Oct 14 13:37:50 1991 Roland H. Pesch (pesch at cygnus.com)
574
575 * doc/gdb.texinfo: Catch up to changes recorded here in ChangeLog
576 (nodes Continuing and Stepping; Memory; Targets) clarifications
577 due to Larry Breed
578
579 Fri Oct 11 23:27:06 1991 John Gilmore (gnu at cygnus.com)
580
581 * tm-{irix3,mips,nindy960,pn,symmetry,vx960}.h: Move
582 REGISTER_U_ADDR to corresponding xm- file. Sugg. by Peter Schauer.
583

585
586 * m68k-tdep.c (m68k_push_dummy_frame, m68k_pop_frame): Add
587 generic routines for calling inferior functions.
588
589 * blockframe.c (inside_main_scope, inside_entry_scope): New.
590
591 * copying.awk: Filter formfeeds out of copying & warrantee.
592 Make them available as `show copying' and `show warrantee' also.
593 * main.c (print_gnu_advertisement): Advt `show' commands.
594
595 Thu Oct 10 17:25:47 1991 John Gilmore (gnu at cygnus.com)
596
597 * mach386-xdep.c: Even when cross-compiling, leave in the
598 core-file reading code.
599 * core.c (get_core_registers): Avoid coredump if no .reg section.
600
601 Wed Oct 9 17:03:34 1991 John Gilmore (gnu at cygnus.com)
602
603 * mipsread.c, coffread.c: initialise TYPE_VPTR_FIELDNO to -1.
604 This avoids coredumps under `set print object on' in value_headof
605 (called erroneously by value_from_vtable_info) for `p &struct'
606 or `p *struct'. From Peter Schauer.
607
608 Mon Oct 7 00:06:52 1991 John Gilmore (gnu at cygnus.com)
609
610 * Makefile.in: Roll version to 4.1.2.
611 * dbxread.c: Use aout64.h, not a.out.gnu.h. Get external symbol entry
612 size from BFD (but, FIXME, we don't yet read external nlists's and
613 convert them to internal nlists's before handling them -- we still
614 assume they have the same size and alignment.) Use SET_NAMESTRING
615 everywhere useful.
616 * exec.c (exec_file_command): Move dead coff-encapsulation code
617 to BFD.
618 * m88k-tdep.c, m88k-xdep.c: Remove encap test and #inc <a.out.h>.
619
620 Fri Oct 4 22:30:06 1991 John Gilmore (gnu at cygnus.com)
621
622 * configure.in, tm-i386v.h, xm-i386v.h: Intel 386 Mach host port.
623 * xm-i386mach.h, mach386-xdep.c, xconfig/i386mach: New files.
624
625 Fri Oct 4 17:04:31 1991 Per Bothner (bothner at cygnus.com)
626
627 More patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
628 * mips-xdep.c (store_inferior_registers): Don't try to
629 write the (pseudo) FP.
630 * mipsread.c (parse_partial_symbols): Improved algorithm for
631 setting pst->texthigh.
632
633 Fri Oct 4 16:47:32 1991 Roland H. Pesch (pesch at cygnus.com)
634
635 * doc/Makefile: make TEXINPUTS include . everywhere
636
637 Fri Oct 4 00:35:56 1991 John Gilmore (gnu at cygnus.com)
638
639 * coffread.c, dbxread.c, symfile.c, symmisc.c, symtab.h: Remove
640 vestiges of typevectors, which were for symsegs and are no longer
641 used. (From a question by Eliot Dresselhaus
642 <dresselh@RFT30.nas.nasa.gov>).
643
644 Thu Oct 3 09:33:26 1991 John Gilmore (gnu at cygnus.com)
645
646 * dbxread.c, coffread.c: static-ize functions that were
647 gratuitiously external. (From Fred Fish.)
648
649 * c-exp.y: sym->class to SYMBOL_CLASS (sym).
650
651 * dbxread.c (dbx_lookup_type): Keep doubling size of typevector
652 until it is large enough.
653
654 * dbxread.c (read_type): Handle error case slightly better.
655 Make complaint message not C++-specific.
656
657 Wed Oct 2 17:21:07 1991 Stu Grossman (grossman at cygnus.com)
658
659 * infrun.c (wait_for_inferior): Fix step/next so that you only
660 stop at the beginning of a new line. This fixes various problems
661 with for loops, nested if-else's and switch statements.
662
663 Tue Oct 1 06:33:55 1991 John Gilmore (gnu at cygnus.com)
664
665 * symtab.c (lookup_symtab_1, lookup_symbol): "fatal" errors
666 between symtabs and psymtabs become ordinary error()s.
667
668 * dbxread.c (read_dbx_symtab): Relocate end_of_text_addr
669 properly, making "end pc" correct in shared lib psymtabs.
670 (From Guy Harris <guy@auspex.com>.)
671
672 Mon Sep 30 13:15:31 1991 John Gilmore (gnu at cygnus.com)
673
674 * dbxread.c: Enable, but soften, const_vol_complaint.
675 (read_dbx_symtab): N_STSYM and N_LCSYM define static vars.
676 Ditto Gould N_NBSTS and N_NBLCS. Also, all types in the psymtab
677 should be file-scope, not global.
678 (read_struct_type): Remove ancient multiple-inheritance warning.
679 (read_range_type): Check base type, complain & patch if undefined.
680 * stack.c (frame_info): Demangle the function name in `info stack'.
681 (From Peter Schauer)
682
683 Sat Sep 28 10:02:33 1991 John Gilmore (gnu at cygnus.com)
684
685 * eval.c (evaluate_subexp_for_address): Don't use
686 TYPE_POINTER_TYPE directly (it might be zero if this type has
687 never had a pointer created before); use lookup_pointer_type.
688 * symtab.c (lookup_method_type): Arguments were swapped in all
689 callers, so fix it here. I'm amazed this worked at all!
690
691 Fri Sep 27 18:09:31 1991 John Gilmore (gnu at cygnus.com)
692
693 * c-exp.y, m2-exp.y: Define more yysymbols that happen to be
694 "bss" rather than "data" symbols, but which still conflict.
695 * m2-exp.y: Lint.
696
697 * coffread.c (coff_symfile_read): Use xmalloc, not malloc.
698 * core.c (core_files_info): Shorten output.
699 * exec.c (exec_files_info): Ditto.
700 (build_section_table): Ignore zero-length sections.
701 * language.c, printcmd.c: Lint.
702 * language.h (get_frame_language): Declare.
703 * saber.suppress: update.
704 * stack.c (find_relative_frame): Remove complex code that was
705 #if 0'd, stick with simple code. Lint.
706 * saber.suppress: Update a bit.
707 * symfile.c (add_symbol_file_command): Add "?" to question.
708 * utils.c (parse_escape): Avoid \a due to bdead compilers.
709 * value.h: Declare typedef_print.
710
711 * valprint.c (val_print, type_print_base): TYPE_CODE_RANGE less
712 kludgey.
713
714 * nindy-tdep.c (nindy_frame_chain_valid): Use lookup_misc_func.
715 (Reported by Mark Peek <mark@imagen.com>.)
716
717 * solib.c (solib_map_sections): Relocate all sections, even
718 though only the text section's size is tracked. Mark ld_text
719 for eventual elimination as we generalize to N sections.
720
721 * infrun.c (wait_for_inferior): Don't check if the PC is in a
722 call_dummy if we were stopped by a random signal that is being
723 passed to the program. This produced wierd results when calling
724 functions in the inferior and signals (e.g. SIGALRM) were in use.
725
726 Tue Sep 24 18:05:30 1991 John Gilmore (gnu at cygnus.com)
727
728 * infrun.c (IN_SIGTRAMP): Not parenthesized properly.
729 Bugfix from Paul Eggert <eggert@twinsun.com>.
730 * tm-ultra3.h (IN_SIGTRAMP): Ditto.
731 * valprint.c (print_floating): Print 9 digits for IEEE floats.
732 From Paul Eggert.
733
734 Mon Sep 23 15:50:07 1991 John Gilmore (gnu at cygnus.com)
735
736 * Makefile.in: Roll VERSION to 4.1.1.
737 * source.c (line_info): Peter Schauer fixes a bug I introduced in
738 hex conversion.
739
740 Fri Sep 20 16:10:52 1991 John Gilmore (gnu at cygnus.com)
741
742 GDB-4.1 release!
743
744 * Makefile.in (VERSION): Set to 4.1.
745 * language.c (set_language_command): Print useful help message,
746 and restore the language string after giving help.
747 * valprint.c (typedef_print): Print typedef in C or M2.
748 * symtab.c (list_symbols): Use it.
749 * main.c (main): Avoid any output before (gdb) prompt when -q.
750 * language.c (set_language_command): Handle errors by restoring
751 the language string to its current state (fix from A. Beers).
752 * doc/gdbint.texinfo: Roll in information from README. Rearrange
753 "how to install" and "how to print the doc" stuff so it drops
754 easier into README.
755 * configure.in: Rename rtpc CPU to romp to match config.sub.
756 * README, WHATS.NEW, TODO: Update for gdb-4.1.
757
758 Fri Sep 20 17:39:14 1991 Roland H. Pesch (pesch at cygnus.com)
759
760 * doc/gdb.texinfo: Updates from ChangeLog. set/show write,
761 autoloading shared libs, copyright etc on GDB startup, clean up $_
762 and $__ index refs, set/show listsize and related updates to list
763 cmd. New host/target configs.
764
765 Fri Sep 20 15:46:00 1991 Roland H. Pesch (pesch at cygnus.com)
766
767 * doc/Makefile: generate aux version-no file doc/gdbVN.m4
768 from main Makefile.in version definition
769 doc/gdb.texinfo: use version recorded in doc/gdbVN.m4 for current
770 GDB version no refs
771 Makefile.in (setup-to-dist): generate doc/gdbVN.m4
772
773 * doc/gdb.texinfo: merge new language-switching and lang-specific
774 doc by Andrew Beers
775
776 Fri Sep 20 15:00:57 1991 Per Bothner (bothner at cygnus.com)
777
778 * mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
779 compilers (which may lack stddef.h).
780
781 Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com)
782
783 * dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and
784 N_WARNING are the same except for the N_EXT bit, so just use their
785 values alone, rather than OR-ing them with N_EXT.
786
787 Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com)
788
789 * mipsread.c (parse_lines): Deal with negative extended line
790 offsets correctly.
791
792 * c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid
793 global symbol conflicts.
794
795 Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
796
797 * .gdbinit: Move 'set complaints' to top, so it runs even in
798 case we aren't debugging GDB.
799 * language.c (_initialize_language): Fix type check and range
800 check documentation strings.
801 * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
802 language.c can use it. (Though language.c should really not be
803 handling warnings/errors the way it does, FIXME.)
804 * symtab.c (lookup_primitive_type): const lint.
805
806 Bugfix from Peter Schauer:
807 * source.c (lines_to_list): Make signed, to avoid comparison
808 going unsigned and complaining that -3 is too high for 21 lines.
809 * stack.c (lines_to_list): Ditto.
810
811 Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
812
813 * Makefile.in (HFILES): Add minimon.h.
814 (VERSION): Roll version number to 4.0.95.
815 (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
816 New rules for building distributions. Normal distribution
817 is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
818 one level up from here; it calls make-proto-gdb.dir to build a
819 directory `proto-gdb' which is an image of the release. The old
820 `gdb.tar.Z' rule still works too.
821 * config.sub, configure: Roll in latest from ..
822
823 Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
824
825 * doc/gdbint.texinfo: Reorder contents; reorganize new-host,
826 new-target, and new-config chapters; fix minor typos; come closer
827 to usual GNU markup conventions for @file @samp @code @var.
828
829 Thu Sep 19 17:04:12 1991 Per Bothner (bothner at cygnus.com)
830
831 Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
832 * mipsread.c (parse_partial_symbols): Enter the name of all
833 structs/unions... into the psymtab so we can access them if the
834 symtab is not read in.
835 * mips-tdep.c: Remove some unneeded #includes.
836 * xconfig/dec3100: Add HAVE_STRSTR.
837
838 Thu Sep 19 15:14:23 1991 John Gilmore (gnu at cygnus.com)
839
840 * Makefile.in: Circumvent Sun Make bug on *-exp.tab.o.
841 * c-exp.y, m2-exp.y: Lint.
842 * m2-exp.y: Avoid using yytname[] which is a Bison-ism.
843 * valprint.c (val_print_fields): Check for stub type.
844 * mipsread.c (_initialize_mipsread): Avoid using
845 builtin_type_void at initialize time.
846 (mipscoff_symfile_read): use it now.
847
848 Wed Sep 18 15:55:51 1991 John Gilmore (gnu at cygnus.com)
849
850 Merge multiple-language support, and partial Modula-2 support,
851 from Andrew Beers <beers@cs.buffalo.edu>.
852
853 * i387-tdep.c: New file, consolidates most 80387 support,
854 and eliminates host dependency on double<->extended conversions.
855 * i386-xdep.c, symm-xdep.c: Remove most 387 support.
856 * xconfig/i386{sco,v,v-g,v32,v32-g}: Now need i387-tdep.o.
857
858 * symfile.c (allocate_symtab): New fn, consolidates the work
859 of allocating and initializing a new struct symtab. Set the
860 language of the symtab based on its filename extension.
861 * symfile.h: Declare it.
862 * mipsread.c (new_symtab): Use it. Minor formatting changes.
863 * dbxread.c (end_symtab): Use it.

928 declarations, and definitions.
929
930 Misc fixes:
931

933 initialization, print its message and then exit(1) from GDB.
934

946
947 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
948
949 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
950 entries are enclosed herein. Not all of these changes
951 have been merged into the master GDB sources -- check the
952 ChangeLog above here for the merge log.
953
954 Mon Jun 3 17:05:45 EDT 1991
955
956 m2-exp.y Created. Tested outside of GDB for a few days. Proper
957 operators were added, C specific operators and tokens
958 removed. yylex() revamped to some extent. Still things
959 missing from the grammar, such as sets.
960 Tested for two weeks in GDB v3.5.
961
962 Tue Jun 11 17:23:48 EDT 1991
963
964 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
965 so they are built-in. Sort of a hack.
966
967 Fri Jun 14 12:53:51 EDT 1991
968
969 m2-exp.y Added range checking for numeric constants. Any numeric
970 constant is assumed to be of builtin type INTEGER unless:
971 (1) it is octal or hexadecimal, in which case it is a
972 CARDINAL; (2) it is too big to fit into an INTEGER, in
973 which case it is a CARDINAL.
974 eval.c Added simple range checking for +, -, and * on integers.
975 Doesn't work very well for *, since 6 * 1,000,000,000 =
976 1,705,032,704, which fails the simple test of result >=
977 first_operand, no matter in what order the operands are.
978
979 Tue Jun 18 14:11:30 EDT 1991
980
981 Broke the parser into parts, one containing the C grammar and the other
982 containing code to be shared by all of the grammars.
983
984 The following files no longer exist:
985
986 expread.y
987 expread.tab.c
988
989 The following files were added:
990
991 c-exp.y (The C grammar)
992 m2-exp.y (The Modula-2 grammar)
993 parser-code.c (Code that is shared by the above grammar)
994 parser-code.h
995 parser-defs.h
996
997 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
998 now necessary to use the Bison compiler compiler, since it
999 will generate function/variable prefixes other than yy.
1000
1001 Tue Jun 18 16:47:49 EDT 1991
1002
1003 symtab.[ch] Added the external variable working_lang, than holds the
1004 value of the current working language.
1005 Added the ennumerated type language_mode, with the values
1006 language_auto and language_manual, the former meaning that
1007 GDB sets working_lang as needed, and the latter meaning
1008 that the value of working_lang is totally under user
1009 control.
1010 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
1011 REAL, BOOLEAN and CHAR. Also added the type codes
1012 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
1013 utils.c Added set_language_command and show_language_command to
1014 implement the GDB support commands "set language" and
1015 "show language".
1016 expression.h A number of identifiers were added to the type exp_opcode
1017 to facilitate Modula-2 builtin functions, integer
1018 division, and array indexing.
1019
1020 Wed Jun 19 13:25:58 EDT 1991
1021
1022 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
1023 if the language specified by working_lang requires the use
1024 of strict typing of expressions. Eventually, even this
1025 will be able to be changed by the user.
1026 Added the macro RANGE_CHECK, which evaluates to non-zero
1027 if the language specified by working_lang requires the
1028 checking of a value against the domain of its type.
1029 Eventually, even this will be able to be changed by the
1030 user.
1031 language.[ch] Predicates involving types (simple_type, ordered_type,
1032 same_type, integral_type, numeric_type, character_type,
1033 boolean_type, float_type) are added. These predicates are
1034 based on the current value of working_lang, and are handy
1035 in type-checking.
1036
1037 Wed Jun 19 15:39:34 EDT 1991
1038
1039 eval.c Added the function type_array_rank which computes the rank
1040 of an array type.
1041 valarith.c Added the funtion value_bool, which when given a integer
1042 value.h value (ie. struct value *) as an argument, it returns a
1043 boolean value (ie. struct value *) true if that integer
1044 is non-zero, and a boolean value false otherwise.
1045 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
1046 will print out properly.
1047
1048 Wed Jun 19 16:36:34 EDT 1991
1049
1050 valops.c Added the function value_capitalize, which returns it
1051 value.h argument capitalized if its argument is a lowercase
1052 letter, or the argument unchanged if its argument is not a
1053 letter.
1054 valarith.c Added the function range_check_p, which returns non-zero
1055 value.h if its value argument is between the integral bounds upper
1056 and lower.
1057 Added the function range_check_enum_p, which makes sure
1058 that its value argument is a valid member of the domain of
1059 its type argument.
1060 Added the function range_check_range_p, which makes sure
1061 its value argument lies between the upper and lower bounds
1062 of its type argument, which must be a ranged type.
1063 Added the function check_array_index, which range and type
1064 checks an index of an array.
1065 Added the function value_multi_subscript, which computes
1066 array[idx1,idx2...idxN], given a value array and an array
1067 of values representing indicies.
1068 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
1069 unpack_long to work with TYPE_CODE_BOOL and
1070 TYPE_CODE_CHAR.
1071
1072 Wed Jun 19 18:04:08 EDT 1991
1073
1074 symtab.c Stored pervasive types in a structure and make
1075 lookup_pervasive_type() a lookup function that was based
1076 on working_lang. If lookup_pervasive_type() returned
1077 non-zero, then that value was returned (a fix, since
1078 before it simply wouldn't return the pervasive type.)
1079 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
1080 non-zero if the language specified by working_lang means
1081 "conversion" when it says "cast".
1082 valops.c Added the function value_real_cast(), which performs a
1083 value.h *cast*, not a *conversion*, which is what value_cast()
1084 does when it can. In particular,
1085 value_cast(<float_type>,4) = 4.0, while
1086 value_real_cast(<float_type>,4) = some mess.
1087 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
1088 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
1089 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
1090 and MIN on integral types. *NOTE*: These are currently
1091 hardcoded to work only if there are 8 bits per storage
1092 unit. FIXME.
1093 eval.c Made logical functions call value_bool to return a
1094 properly typed boolean value, based on working_lang.
1095
1096 Thu Jun 20 11:55:27 EDT 1991
1097
1098 valprint.c Types now print out in a Modula-2 fashion. This works for
1099 the cases when the type is printed out step-by-step, that
1100 is, it doesn't work when the name of a structured type
1101 (which includes the keyword "struct", etc.) is simply
1102 displayed.
1103 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
1104 since type specifications in C and Modula-2 are very
1105 different. The C printing of a type is very recursive,
1106 whereas in Modula-2 it is generally very simple. C has
1107 type prefixes and suffixes, which have no real analogue in
1108 Modula-2. Maybe type_print() should call a language
1109 specific type printer. This is also advantageous if we
1110 compile GDB to exclude some of the languages. We'll just
1111 leave those functions out.
1112
1113 Thu Jun 20 16:57:10 EDT 1991
1114
1115 dbxread.c When reading the complete symbol table in (via
1116 psymtab_to_symtab()), the number and types of function
1117 arguments are added to a function type. define_symbol()
1118 calls add_param_to_type() to accomplish this.
1119 Assumption: when we come across a function definition
1120 (N_FUN symbol with an 'f' or 'F' in the name), its
1121 arguments will appear before another function definition.
1122 When a function is found, a pointer to its type is placed
1123 in the global in_function_type. Changes that
1124 add_param_to_type() makes are to this global.
1125 valprint.c The type of a function now includes (for Modula-2) the
1126 types of its parameters.
1127 eval.c Type checking and a check for the proper number of
1128 arguments is now done for function calls. Not sure of the
1129 impact this has on C++ member function yet.
1130
1131 Thu Jun 20 19:58:48 EDT 1991
1132
1133 valprint.c Rewrote the type printer. Broke it into two language
1134 specific parts, adding the functions type_print_m2() and
1135 type_print_m2_1().
1136 An unfortunate consequence is this: if you debugging a C
1137 program in Modula-2 mode (why?), info types does not work
1138 well with regular expressions, since the types are printed
1139 out in Modula-2 terminology, but stored in C terminology.
1140 language.[ch] Added the functions new_type_last(), type_keyword(), and
1141 type_sep() to aid in the printing of typedefs.
1142 symtab.c Made the printing of typedefs as language independent as
1143 possible through calls to new_type_last(), type_keyword(),
1144 and type_sep().
1145
1146 Fri Jun 21 11:50:26 EDT 1991
1147
1148 dbxread.c Check all incoming ennumerated types. If it looks like
1149 Modula-2's BOOLEAN type, then change the type_code of the
1150 type to TYPE_CODE_BOOL so we can process it as a boolean
1151 variable.
1152 valprint.c Replaced some of the 0x%x with calls to sprintf and
1153 hexformat() in val_print().
1154 language.[ch] Added the function hex_to_string(), which converts its
1155 integral argument to a hexadecimal number (format is
1156 language based) and returns the result as a string.
1157
1158 Mon Jun 24 12:25:07 EDT 1991
1159
1160 valprint.c Some functions call type_print_1() directly, instead of
1161 value.h using type_print(), so they can specify where (column) to
1162 print things. Since type_print() takes care of language
1163 dependence, that needs to be called first. Added a
1164 parameter depth to type_print() (so it is now like
1165 type_print_1). Changed type_print to type_print_at, and
1166 made type_print a macro that passes a depth argument of
1167 zero.
1168 symmisc.c Changed all calls to type_print_1 to calls to
1169 type_print_at.
1170 Makefile.dist Made it possible to build GDB for a specific set of
1171 depend languages. Do this by passing a definition for the macro
1172 LANGS to make. LANGS should be a string containing a
1173 space-separated list of language names (ie. LANGS="c m2").
1174 The default is to build all languages. Note that grammar
1175 files must follow the naming convention of <lang>-exp.y.
1176 gdb.lang This holds the current value of the LANGS macro. It is
1177 examined every time make is called, and is updated if
1178 necessary.
1179 eval.c Added #ifdef _LANG_<lang> to these files.
1180 expread.c Still need to add them to dbxread.c and coffread.c.
1181 main.c
1182 source.c
1183 symtab.c
1184 utils.c
1185 valarith.c
1186 valprint.c
1187
1188 Mon Jun 24 16:33:11 EDT 1991
1189
1190 language.[ch] Added the functions hexformat_pre() and
1191 hex_to_string_pre(), which take a prefix argument to
1192 include in the format string. Thus, hexformat_pre("08") will
1193 return "0x08x" (if the working language is language_c).
1194 Made hexformat() and hex_to_string() calls to the above
1195 with "" as the prefix argument.
1196
1197 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
1198 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
1199 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
1200 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
1201 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
1202 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
1203 valprint.c, vax-pinsn.c
1204
1205 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
1206 calls to hexformat() and hex_to_string(). Format strings without
1207 the leading "0x" were ignored.
1208
1209 depend Updated to take the above into account.
1210
1211
1212 Tue Jun 25 15:27:18 EDT 1991
1213
1214 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
1215 and type_check_t to keep track of the current state of
1216 range and type checking.
1217 main.c Added the variables range_mode, range_check, type_mode,
1218 and type_check to record the current state of range and
1219 type checking. Added initialization code to main().
1220 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
1221 the above variables.
1222
1223
1224 Tue Jun 25 17:57:08 EDT 1991
1225
1226 dbxread.c process_one_symbol() updates the variable (enum language)
1227 source_lang based on the extension of the filename
1228 contained in the N_SO sybmol that started this symtab.
1229 When end_symtab() is called, the value of source_lang is
1230 put into the language field.
1231 stack.c select_frame() sets working_lang (and possibly type_check
1232 and range_check) to the language field of the symtab
1233 associated with the frame that is selected if working_mode
1234 is language_auto. If working_mode is language_manual, a
1235 warning is printed and working_lang is not set.
1236 language.c Added the function set_type_range(), which sets the value of
1237 type_check and range_check (if their modes call for
1238 automatic setting) based on the current value of
1239 working_lang. A non-zero argument will cause the current
1240 settings to be output.
1241
1242
1243 Wed Jun 26 14:51:40 EDT 1991
1244
1245 eval.c Added range checks on assignment.
1246 m2-exp.y Added the grammar for sets to the language. Currently,
1247 these do not do anything except print an error message.
1248
1249 Wed Jun 26 17:01:04 EDT 1991
1250
1251 m2-exp.y Added the ability for parse_number() to parse negative
1252 numbers. A global flag is set upon encountering a unary
1253 minus. This was done to make, for example, 1 parse as a
1254 CARDINAL, and not as an integer, per Wirth's examples in
1255 Programming in Modula-2 ed.4.
1256 valprint.c Added support for "set radix 2" by then setting
1257 output_format to 't'.
1258 eval.c Implemented range checking on subrange types. Added calls
1259 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
1260 Implemented MIN and MAX for ennumerated types. The
1261 minimum value of an ennumerated type is defined by Wirth
1262 as the first identifier, and the maximum as the last.
1263 m2-exp.y Made octal numbers ending with "B" be characters and those
1264 ending with "C" be numbers, per Wirth's book. (p. 34)
1265
1266 Thu Jun 27 14:11:52 EDT 1991
1267
1268 stack.c select_frame() now only sets working_lang, it does not
1269 notify the user. If working_mode is language_manual, then
1270 a warning is issued once.
1271 main.c At the end of each call to execute_command(), working_lang
1272 is checked against the local static (enum language)
1273 current. If they differ and working_mode is
1274 language_auto, the new settings of language, type and
1275 range checking are printed out.
1276 stack.c Modified frame_info() to include the language of the
1277 current frame in the output of "info frame".
1278 language.[ch] Added the function language_str() which returns the name
1279 of the current language.
1280
1281 Fri Jun 28 15:33:14 EDT 1991
1282
1283 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
1284 the language. INCL and DECL currently cause an error,
1285 since sets are not implemented yet. INC and DEC are
1286 implemented as PREINCREMENT/PREDECREMENT with one
1287 argument, and as ASSIGN_MODIFY with two arguments.
1288 eval.c Added type checking to the above cases.
1289 value.h Added not_lval_constant to the lval_type ennumerated type.
1290 not_lval_constant means that the value is a constant
1291 value; that is 3 or 'a' or TRUE, not as in a constant
1292 identifier. This is used to help coerce numbers such as 3
1293 to either signed or unsigned numbers.
1294 valops.c Added the function value_coerce_constants() which coerces
1295 constant integers as following: if one is a constant and
1296 the other is not, the constant's type is set to the type
1297 of the other argument. If both are constants and one is
1298 signed, the other is converted to a signed constant.
1299
1300 Sat Jun 29 17:26:29 EDT 1991
1301
1302 valarith.c Added a better range checker. It now checks range
1303 (successfully) on integral operations [+-] (signed and
1304 unsigned) for any C sized type. Still does not work well
1305 for multiplication.)
1306 int_in_size() returns an integer that is coerced to fit into
1307 specified number of bytes.
1308
1309 Mon Jul 1 13:04:14 EDT 1991
1310
1311 language.[ch] Added the function binop_result_type(), which returns the
1312 builtin (struct type *) type that would be the result of a
1313 binop on the two values V1 and V2.
1314
1315 Wed Jul 3 19:22:53 EDT 1991
1316
1317 source.c Extended source_info() to include the source language in
1318 the output from "info source".
1319
1320 Fri Jul 5 13:48:52 EDT 1991
1321
1322 utils.c Moved the support functions for the GDB set/show commands
1323 dealing with language into language.c.
1324 language.c Added the function language_info(), which displays info
1325 about the current working language, type and range check
1326 settings. Called via the GDB command "info language".
1327 Added an initialization routine _initialize_language(),
1328 that sets defaults for the language, type and range
1329 variables and sets up the new GDB commands.
1330 main.c Language setup moved to language.c.
1331 depend Rebuilt.
1332
1333 Mon Jul 8 10:10:22 EDT 1991
1334
1335 valarith.c Debugged the range checker for arithmetic. Still does not
1336 work for multiplication very well.
1337
1338 Mon Jul 8 12:40:37 EDT 1991
1339
1340 language.[ch] Added the function value_true() which returns non-zero if
1341 its argument represents a boolean true value.
1342 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
1343 check the truth of an expression.
1344
1345 Thu Jul 11 12:51:34 EDT 1991
1346
1347 language.[ch] Added the predicate structured_type(), which returns
1348 non-zero if the argument is a structured type.
1349 Added the predicate pointer_type(), which returns non-zero
1350 if the argument is a pointer type.
1351 eval.c Added the ability to do addition and substraction on
1352 pointers and integers. This case simply bypasses the
1353 type checker.
1354
1355 Thu Jul 11 14:41:42 EDT 1991
1356
1357 include/stab.def
1358 Added the symbol N_DEFD (0x4a) which is a definition
1359 module dependency that is used by the GNU Modula-2
1360 compiler and the linker. It is not important to GDB,
1361 except that [dbx|coff|mips]read.c should ignore these
1362 symbols.
1363
1364 Fri Jul 12 16:07:00 EDT 1991
1365
1366 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
1367 0 in val_print(). Also added statements to the else part
1368 to coerce type (argument to val_print) to a pointer type
1369 if it is an "array of unspecified length".
1370 valops.c Added the function value_m2_string(), which returns a
1371 (value) value which is a constant string, whose type is
1372 (ARRAY [0..n] OF CHAR). The length field of the type
1373 structure is set to zero, so it will be interpreted as an
1374 "array of unspecified length".
1375 stack.c Moved the language/frame mismatch check to
1376 main.c:execute_command().
1377 main.c The working language is recorded each time
1378 execute_command() is executed. If working lang has
1379 changed during its execution, then the new
1380 language/type/range info is printed out for the user. If
1381 the working language does not match the language of the
1382 frame, a warning is issued.
1383
1384 Sat Jul 13 16:16:39 EDT 1991
1385
1386 eval.c Moved all the type-checking stuff for operators to
1387 language.[ch] language.c. This is so we can keep language-specific
1388 stuff (like for what type operators are defined) in
1389 language.c.
1390 language.[ch] Added the function binop_type_check(), which checks to see
1391 if its two (value) arguments are type-compatible with its
1392 opcode argument. The opcode should represent an operation
1393 involving an operator. Also added the macro function
1394 unop_type_check, which calls binop_type_check with a
1395 NULL second argument.
1396 expprint.c Added Modula-2 operators to the op_print_tab, so info
1397 expression.h break works correctly. Also added "op_string", which
1398 returns the string corresponding to the (enum exp_opcode)
1399 opcode that is its argument.
1400
1401
1402 Sat Jul 13 18:26:18 EDT 1991
1403
1404 coffread.c Added code to record the type of function arguments with
1405 each paricular function. Code is very similar to that
1406 added to dbxread.c.
1407 dbxread.c Moved add_param_to_type() to symtab.c
1408 symtab.[ch] Added function add_param_to_type() from dbxread.c
1409
1410 *** NOTE: The above additions have not been tested.
1411
1412 Mon Jul 15 12:50:47 EDT 1991
1413
1414 langauge.[ch] Added the functions type_error and range_error, which work
1415 like error() except if the type/range mode is set to
1416 *_mode_warn, then they do not do a return_to_top_level(),
1417 but merely print a warning.
1418 Also changed [set|show]_[type|range]_command() to support
1419 the new "warn" feature.
1420
1421 Thu Jul 18 17:50:54 EDT 1991
1422
1423 mipsread.c Added code to record the type of function arguments with
1424 each particular function. Code is very similar to that
1425 added to dbxread.c.
1426
1427 *** NOTE: The above additions have not been tested.
1428
1429 Fri Jul 19 11:19:10 EDT 1991
1430
1431 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
1432 UMIN_OF_SIZE, which when given a size of a numeric type,
1433 return the maximum and minimum value it can hold. UMAX...
1434 and UMIN... return the result for unsigned types.
1435 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
1436 struct types. They call above macros.
1437 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
1438 avoid a name conlict with the above.
1439 c-exp.y Added range checking on numeric constants in
1440 parse_number() for completeness.
1441 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
1442 return 0 if working_lang is not language_c.
1443
1444 Thu Aug 8 14:17:22 EDT 1991
1445
1446 main.c
1447 printcmd.c
1448 breakpoint.c Documentation strings of some commands changed to
1449 eliminate the references to the C language where
1450 appropriate.
1451
1452 Tue Aug 13 15:48:03 EDT 1991
1453
1454 m2-exp.y Added qualified identifiers to the grammar. The semantics
1455 are slightly different from those of the GDB operator ::
1456 c-exp.y
1457 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
1458 type_exp, where type_exp is any valid type expression.
1459 expression.h
1460 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
1461 printcmd.c Modified ptype_command() so it actually parses the input
1462 (necessary for type expressions with scope qualifiers).
1463 Added the function ptype_eval() which expects an
1464 expression composed of one OP_TYPE element.
1465 *.[ch] Replaced all occurences of parse_c_expression with
1466 parse_expression
1467 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
1468
1469 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
1470
1471 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
1472
1473 Small fixes from Peter Schauer:
1474
1475 * infrun.c (child_attach): Lint.
1476 * solib.c (find_solib): Handle shared libs version 2.
1477
1478 Small fixes from David Wood:
1479
1480 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
1481
1482 Small fixes:
1483
1484 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
1485 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
1486
1487 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
1488 chars_per_line is at maximum (user typed `set width 0'). Fix
1489 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
1490
1491 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
1492
1493 * coredep.c: include ptrace.h where necessary.
1494 * mipsread.c(parse_lines): fix unsigned char problem that was
1495 messing up line numbers on SGI's and possibly other MIPS based
1496 platforms.
1497 * infrun.c (child_create_inferior): use better test to check
1498 return val from setpgrp().
1499 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
1500 for sgi/irix support.
1501
1502 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
1503
1504 * mipsread.c (parse_symbol): Put non-static procedures
1505 in the global block.
1506
1507 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
1508
1509 Patch together `text_start' and `text_end' for 29K port.
1510
1511 * exec.c (exec_command): If NEED_TEXT_START_END, define the
1512 variables and set them based on the exec file.
1513 * am29k-tdep.c: declare text_start.
1514 * valops.c (call_function_by_hand): declare text_end.
1515
1516 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
1517 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
1518 because machines that do this will also have to know to
1519 set NEED_TEXT_START_END. Besides, it was a redundant way to
1520 say the same thing.
1521 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
1522 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
1523 NEED_TEXT_START_END.
1524
1525 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
1526
1527 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
1528
1529 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
1530 Pass MUNCH_DEFINE to munch whenever we run it.
1531 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
1532 format string; use 0x%x instead.
1533 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
1534 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
1535 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
1536 * inflow.c: Handle `short' process group IDs.
1537 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
1538 and check for ptrace errors.
1539 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
1540 (coff_symfile_init): Initialize text_bfd_scnum.
1541 (read_coff_symtab): Use it to find the text [and absolute?] sections.
1542 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
1543 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
1544 Merge target arm case with other "easy" cases. Add target
1545 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
1546 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
1547 process).
1548 * minimon.h, remote-adapt.c, remote-mm.c: Add.
1549 * munch: Cope with RT/PC putting fns in data segment.
1550 Restore ability to override `nm' by specifying MUNCH_NM.
1551 * xconfig/rtbsd, xconfig/ultra3: New host systems.
1552 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
1553 and remote-adapt. Remove encapsulated coff #define's (the
1554 support should go in BFD, and gdb shouldn't know or care).
1555 * tconfig/a29k-kern: Same, but for remote kernel debugging.
1556 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
1557 * tm-29k.h: Update BADMAG (though it should go away).
1558 Allow the register definitions to be overridden in another
1559 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
1560 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
1561 DUMMY_SAVE_GR96, for handling kernel calling conventions
1562 that use GR64+ rather than GR96+.
1563 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
1564 remote debugging of Ultra3 kernel. Includes tm-29k.h and
1565 overrides various things.
1566
1567 * remote-mm.c (mm_attach, mm_wait): Handle attach like
1568 child_attach does, making a clean stop in the newly attached
1569 program.
1570 * remote-eb.c: Lint.
1571
1572 * coffread.c: Make coffread independent of any particular
1573 variant of COFF. Avoid #include-ing any particular one except
1574 internalcoff.h. BFD now passes key values for symbol reading
1575 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
1576 and the symbol masks and shifts); use them.
1577 Remove obsolete end_of_text_addr.
1578
1579 * exec.c: Remove unused include files.
1580
1581 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1582
1583 * Makefile.in (documentation targets): Pass $(M4).
1584 Bugfix from eggert@twinsun.com (Paul Eggert).
1585
1586 * stack.c (down_silently_command): Check for stack existence.
1587
1588 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1589
1590 * Makefile.in (VERSION): Update to 4.0.3.
1591
1592 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1593
1594 * core.c (core_file_command): Print frame at coredump with
1595 its level number, by calling print_stack_frame.
1596 * frame.h: Add selected_frame_level, print_stack_frame.
1597 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
1598 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
1599 Change print_sel_frame and print_selected_frame callers to
1600 print_stack_frame.
1601
1602 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
1603 * symfile.c (free_named_symtabs): Ditto.
1604 * main.c (main): wrap_here needs an arg.
1605 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
1606 (solib_add): Avoid noise.
1607 (solib_create_inferior_hook): Lint.
1608 (sharedlibrary_command): Move dont_repeat to here.
1609 * utils.c (error): Call wrap_here to force buffered output.
1610
1611 Small patches from Peter Schauer:
1612
1613 * coffread.c (start_symtab): Free any existing line_vector before
1614 malloc-ing new one.
1615 (read_coff_symtab): Ditto for type_vector.
1616
1617 * source.c (lines_to_list): New variable, replacing function.
1618 (all uses): Use as variable.
1619 (_initialize_source): Add 'set listsize' and 'show listsize'.
1620 * utils.c (lines_to_list): Remove function.
1621 * stack.c (print_frame_info): Use as variable.
1622 * defs.h (lines_to_list): Remove declaration.
1623
1624 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1625
1626 * breakpoint.c (insert_breakpoints): Restore warning about
1627 the program might be running in another process, but only for
1628 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
1629 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
1630
1631 * utils.c (error): if error_pre_print is set, print the string
1632 first.
1633 * main.c (main, print_gnu_advertisement, print_gdb_version):
1634 Reformat legalese so it always prints, but acts as an "I'm here"
1635 message while symbols are being read. If any errors occur,
1636 print a few newlines to set off the message and start it at the
1637 left margin. Remove mention of "help" command, and don't yak
1638 about symbol reading.
1639 (catch_errors): Error string is now printed first in case of
1640 error, not last.
1641 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
1642 suggest the "help" command.
1643
1644 * Makefile.in (VERSION): Set to 4.0.2.
1645
1646 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
1647
1648 * .gdbinit: Remove useless "rr" command. Set complaints
1649 to 1 for people debugging gdb.
1650
1651 * breakpoint.c, remote-vx.c: Reword strings printed by
1652 catch_errors callers.
1653
1654 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
1655
1656 * WHATS.NEW: "history write -> history save". Doc "write on/off".
1657 (Fix from kenc@viewlogic.com.)
1658
1659 Fix some infrastructure to be able to cope with host and target
1660 machines with different sized basic types (ints, ptrs, etc).
1661 (Idea from pierre@la.tce.com (Pierre Willard).)
1662
1663 * values.c (value_from_longest): Rename from value_from_long.
1664 Handle pointer types as well as integers, so that targets with
1665 different pointer sizes from the host can be accomodated.
1666 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
1667 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
1668 uses of value_from_long to value_from_longest.
1669 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
1670 the correct pointer type to value_from_long{est}.
1671
1672 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
1673
1674 * remote-vx.c: Remove obsolete code for calling functions via
1675 vxworks kludge interface (it referenced value_from_long).
1676
1677 * valops.c (value_string): Find malloc with lookup_misc_func, not
1678 raw search.
1679
1680 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1681
1682 Make writing to files work properly. (Fixes to BFD are also needed.)
1683
1684 * core.c (core_open): Open file ourselves, read or r/w, depending on
1685 write_files. Use bfd_fdopenr.
1686 * gdbcore.h (write_files): New variable.
1687 * exec.c (write_files): Define variable, add set&show for it.
1688 (exec_file_command): Use write_files to open for read or r/write.
1689
1690 Make shared library reading happen automatically. These changes
1691 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
1692
1693 * inferior.h (stop_soon_quietly): Add to exported variables.
1694 * infrun.c (child_create_inferior): call solib hook, if defined.
1695 (child_attach): call solib hook, if defined.
1696 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
1697 (find_solib): Use lookup_misc_func rather than hand-rolled.
1698 (symbol_add_stub): New stub for catch_errors.
1699 (solib_add): Avoid output if !from_tty. Catch errors rather
1700 than just calling symbol_file_add and bombing.
1701 (solib_create_inferior_hook): Interface with the target process
1702 to let it read and alloc shared libs, then figure out what it did.
1703
1704 * core.c (validate_files): Fix typo, soften warning.
1705 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
1706
1707 * utils.c (fputs_demangled): Avoid duplicate printing if
1708 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
1709
1710 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
1711 (Fix from pierre@la.tce.com (Pierre Willard).)
1712
1713 * main.c (catch_errors): Change argument to a char * from an int,
1714 since a char * can point to a struct full of glop, but an int
1715 is not guaranteed to be able to hold a pointer.
1716 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
1717 breakpoint_re_set_one, breakpoint_re_set): Adapt.
1718 * core.c (core_open, solib_add_stub): Adapt.
1719 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
1720
1721 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1722
1723 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
1724 by adding .NOEXPORT target.
1725
1726 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1727
1728 * GDB-4.0 release!
1729 * Update README.
1730 * Makefile.in (VERSION): Roll to 4.0.
1731 (gdb.tar.Z): Make refcard.ps as well, for shipment.
1732
1733 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1734
1735 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
1736 more on printsyms.
1737
1738 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
1739 "gdb-all.texinfo"
1740
1741 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
1742
1743 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
1744 reflect above name change
1745
1746 * WHATS.NEW: correct pointer to refcard.
1747
1748 * doc/gdb.texinfo: update New Features, Installing
1749
1750 * doc/gdbint.texinfo: add short description of configure +template
1751
1752 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)

1754 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
1755
1756 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
1757
1758 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
1759 tar file, add dependencies for referenced doc files.
1760
1761 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
1762
1763 * coffread.c, symfile.c, stack.c: saberized.
1764
1765 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1766
1767 * doc/refcard.tex: permuted Essential Commands sec
1768
1769 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
1770 new doc for
1771 set/show symbol-reloading
1772 default set complaints 0
1773 info all-registers
1774 RET-repeat disabled after prompted long displays
1775 processID (attach) interpretation of 2nd GDB cmdline arg
1776
1777 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
1778
1779 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
1780 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
1781 breakpoint.c, main.c: lint.
1782
1783 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1784
1785 Install new configuration scheme for GDB and friends.
1786
1787 * config.sub: Translate ordinary names to three-part names.
1788 * configure: Use three-part names internally.
1789 * configure.in: Translate three-part names to filenames.
1790
1791 * README, WHATS.NEW: Update for gdb-4.0.
1792 * Makefile.in: Roll VERSION to 3.99.
1793
1794 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
1795
1796 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
1797 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
1798 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
1799 to single structures rather than arrays; when passing
1800 their address, use &. This avoids trouble with bdead compilers.
1801 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
1802 instead. This avoids portability headaches.
1803 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
1804 asked to.
1805 * source.c (open_source_file): Avoid ANSI const bdeath by
1806 skipping declaration and then casting result value.
1807 * tm-hp300bsd.h: Clarify comment.
1808 * utils.c (strstr): Result is const char *; ANSI bdeath.
1809 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
1810 since system include file defines it differently from "defs.h",
1811 though the two are equivalent for our purposes.
1812 * tconfig/hp300bsd: Add m68k-tdep.o.
1813
1814 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1815
1816 * tconfig/sun*4: Remove warnings about system assembler.
1817
1818 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1819
1820 * mcheck.c: Avoid warning about undeclared abort fn.
1821 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
1822 it causes recursive calls to error() when used in cleanups.
1823 To do so requires that we make it a function, so we do.
1824 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
1825 * utils.c (do_cleanups): Remove the current cleanup from the
1826 chain *before* calling it, in case error() is called from it.
1827 The result won't be pretty, but won't be an infinite loop either.
1828
1829 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
1830
1831 * dbxread.c (read_struct_type): Grok anon structs for C++.
1832 (vb_name, vptr_name): Null terminate these strings.
1833
1834 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1835
1836 Minor bug fixes from BSD Net2 gdb:
1837
1838 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
1839 returns 0, there is no previous frame.
1840 * breakpoint.c (commands_command): If !from_tty, don't call
1841 input_from_terminal_p().
1842 * dbxread.c (record_misc_function): Speed up slightly.
1843 (compare_psymbols): Ditto.
1844 * infcmd.c (do_registers_info): Take a second argument to
1845 determine whether to print float registers. "info registers"
1846 does not do so anymore. "info all-registers" does, now.
1847 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
1848 arg and ignore it.
1849 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
1850 * inflow.c (initialize_inflow): Set tflags_ours correctly.
1851
1852 Other fixes:
1853
1854 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
1855 executing_breakpoint_commands if we are interrupted by error.
1856 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
1857 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
1858 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
1859 catch_errors() so we can setup the frame regardless of whether
1860 the shared libs work.
1861 * ieee-float.c (double_to_ieee_extended): Get exponent from
1862 right place in little-endian systems. From John Carey.
1863
1864 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1865
1866 * main.c: Remove unused terminating_signals and catch_termination().
1867 (long_options): Terminate with a zero element.
1868 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
1869 (gdb_readline): Make call-compatible with readline.
1870 (init_signals): Improve comments re vfork vs. signal.
1871
1872 * utils.c (prompt_for_continue): Use new gdb_readline().
1873 If we prompt for continuation, we don't let CR repeat the previous
1874 command, once we get back to a prompt. It's too easy to keep
1875 hitting CR, expecting "--more--" prompts, and have some long
1876 command start repeating on you.
1877
1878 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1879
1880 * blockframe.c (frameless_look_for_prologue): Speed up by
1881 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
1882 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
1883 Define two variants, one faster.
1884 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
1885 and return zero, rather than giving an error.
1886 (setup_arbitrary_frame): Initialize the PC in the new frame.
1887 (skip_prologue): Add a second arg saying whether we're just
1888 checking for a frameless function or not.
1889
1890 * core.c (core_open, core_close, core_xfer_memory): Move
1891 section table pointers and bfd* into the target_ops.
1892 (core_open): Allow errors in shared lib reading, etc.
1893 (core_files_info): Describe shared library sections.
1894
1895 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
1896 exec_files_info, set_section_command): Move section table
1897 pointers and bfd* into the target_ops.
1898 (add_to_section_table): Add BFD to section table.
1899
1900 * target.c (target_xfer_memory, target_info): Pass target to
1901 xfer_memory and target_info functions.
1902 * target.h: ''
1903
1904 * gdbcore.h: Move struct section_table.
1905 * target.h: New home of struct section_table.
1906
1907 * solib.c (solib_add): New argument is the target_ops whose
1908 section list is to be added to, if any. Reallocate the
1909 sections in that target to add any that come from shared libs.
1910 (throughout) so_sections renamed to sections.
1911 (solib_xfer_memory): Deleted.
1912 * tm-sunos.h (SOLIB_ADD): Add target argument.
1913 (SOLIB_XFER_MEMORY): Delete.
1914
1915 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1916 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
1917 from target_ops. It's the same on all targets. Add two section
1918 pointers to target_ops.
1919
1920 * stack.c (find_relative_frame): Dump ancient algorithm for
1921 "down", just use handy "next" pointers.
1922 (frame_command): Don't error if there is no stack; let user
1923 set one.
1924
1925 * inflow.c (new_tty_prefork, new_tty): New prefork routine
1926 modifies static state in the parent process; new_tty itself
1927 runs in the child and modifies the child's file descriptors
1928 to match the saved static state.
1929 * infrun.c (child_create_inferior): Call new_tty_prefork,
1930 fork, then new_tty.
1931
1932 * infptrace.c (child_xfer_memory): Add ignored target arg.
1933 * remote-eb.c (eb_xfer_inferior_memory): ''
1934 * remote-nindy.c (nindy_xfer_inferior_memory): ''
1935 * remote-vx.c (vx_xfer_memory): ''
1936 * remote.c (remote_xfer_memory): ''. Rename from
1937 remote_xfer_inferior_memory.
1938
1939 * main.c (main): Only try to attach "corefile" argument if
1940 it starts with a digit.
1941
1942 * symfile.c (symbol_reloading): New "set/show" variable.
1943 (symbol_file_add): Shorten message about symbol reading.
1944 (add_symbol_file_command): Merge with add_syms_addr_command,
1945 since this should work on all targets now.
1946 (stop_whining): Default to zero, to shut up complaints
1947 about bad symbol tables on many systems.
1948 (free_named_symtabs): Just exit unless symbol_reloading.
1949
1950 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
1951 and add comment explaining shared library screw.
1952
1953 * source.c: #if defined => #ifdef.
1954
1955 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1956
1957 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
1958
1959 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1960
1961 * doc/rdl-apps.texinfo: provide default readline-appendix finder
1962 (doc/Makefile knows how to make one for local config)
1963
1964 * Makefile.in: use doc/Makefile for doc targets
1965
1966 * doc/Makefile: GDB documentation now has its own Makefile
1967 doc/refcard.tex: renamed from "gdbrc.tex"
1968 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
1969 doc/gdbint.texinfo: add markup in "Cleanups" chapter
1970
1971
1972 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1973
1974 * values.c (baseclass_addr): When reading target memory, use the
1975 length of the basetype, not the upper type. We've only malloc'd
1976 enough space for the basetype, leading to errors in free().
1977
1978 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
1979 ends up as a function specially, since we know the actual type of
1980 the pointed-to address. This (somewhat) fixes display of
1981 expressions that include misc_function_vector names. Try `cond 1
1982 !strcmp("a","b")' then `i b'.
1983
1984 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
1985 The child can be proceeded from inside wait_for_inferior in
1986 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
1987 getting skipped in that case.
1988
1989 * expprint.c (print_subexp): Use filtered output, since the
1990 subroutines we call use it, otherwise the output is horribly
1991 mangled, since output of wrappable stuff comes out late.
1992
1993 * Makefile.in: Bump VERSION to 3.98.1
1994
1995 * infrun.c (child_create_process): Use execlp to find the
1996 shell to exec our target program. This requires some fiddling
1997 with `environ' since there is no execlpe().
1998
1999 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2000
2001 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
2002 Minor rearrangement of refcard permits two new make targets--
2003 gdbrc.dvi DVI output for refcard, using CM fonts
2004 gdbrc.ps PostScript refcard, using PS fonts
2005
2006 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2007
2008 * GDB-3.98 release.
2009
2010 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
2011 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
2012
2013 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2014
2015 * doc/gdb.texinfo: last changes for release.
2016 Minor typo and formatting fixes; incorporated most fixes remaining from
2017 filed mail commenting on earlier drafts.
2018
2019 Added warnings: pipes don't work in run command;
2020 conditions are converse of assertions;
2021 step over fn without debug info goes to next fn;
2022 vars may have "wrong" values near fn entrance, exit
2023
2024 Added example from Kingston on printing repeated nonadjacent values
2025
2026 Added explicit mention that in Emacs gdb mode C-c and C-z are like
2027 shell mode for signals
2028
2029 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
2030 doesn't sound so much like its parent "Stopping and Continuing"; also
2031 moved entries on continue to top of section, so they don't get lost.
2032
2033 Improved installation directions in appendix, added manual formatting
2034 instructions
2035
2036 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2037
2038 * configure.in: Remove xm.h and tm.h even if we aren't linking
2039 new ones, so "./configure sun4; ./configure none" does the right
2040 thing. Assume that alldeps.mak and depend are already built in
2041 srcdir, and avoid running "make" (particularly "make depend",
2042 which involves "gcc") from inside configure. Build Makefile
2043 directly rather than building Makefile.conf first.
2044 * configure: Regenerate with above changes.
2045 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
2046 to 3.98. Revise gdb.tar.Z procedure to produce a file
2047 called gdb-$(VERSION).tar.Z but which unpacks into a
2048 directory called "gdb". Move non-source files out of
2049 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
2050 (depend): Don't try to do "gcc expread.y".
2051 (expread.o): Update dependencies by hand.
2052
2053 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2054
2055 * doc/gdb.texinfo:
2056 Fixed a variety of small typos that prevented info from formatting
2057 cleanly; altered too-long heading for GPL Appendix, as discussed
2058 w/RMS; Changed date on cover to July 91.
2059
2060 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2061
2062 * doc/gdb.texinfo:
2063 (1) Applied some fixes due to comments from Larry Breed (easier ones
2064 through chapsec 5.2)
2065 (2) Eliminated use of @footnote---had my doubts about it anyways, and
2066 it's broken in latest texinfo
2067 (3) Introduced *some* use of [] for optional arguments, where
2068 explanation is not simpler by listing cmd w arg and cmd w/out arg
2069 separately. Still not using @deffn.
2070 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
2071 couple of headings are too long. Need patches to texinfo or revision
2072 to GPL-2.
2073
2074 * Partial update to README (which still needs work for this
2075 release!): (1) use of configure corrected for new script,
2076 (2) "make gdb.dvi" and "make gdb.info" mentioned.
2077
2078 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
2079
2080 * symtab.c (lookup_symbol): Don't complain right off about
2081 no debug symbols; use the misc function vector first.
2082 (list_symbols): Use misc function vector to find symbols
2083 that don't have debug info, and print them.
2084 (find_pc_symtab): Temporarily avoid fatal() when psymtab
2085 PC range doesn't match symtab PC range, as it does on the
2086 MIPS because our symtab reading isn't perfect.
2087
2088 * dbxread.c (dbx_symfile_read): Make warning about
2089 "no debug symbols" slightly nicer.
2090
2091 * source.c (select_source_symtab): If "main" symbol exists,
2092 but decode_line_spec can't find line info, don't just return
2093 a zero; try other source symtabs or give an error.
2094
2095 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
2096 their low addresses first, then rip through fixing high addrs.
2097
2098 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
2099 <runene@ifi.uio.no>.
2100 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
2101
2102 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2103
2104 * Minor, mostly mechanical, cleanup of doc subdir for clean
2105 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
2106 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
2107
2108 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
2109
2110 Mostly MIPS and general symbol-reading fixups.
2111
2112 * doc/gdbint.texinfo: Add documentation on symbol-reading
2113 interface.
2114
2115 * mipsread.c: Remove kludges around #include "ecoff.h".
2116 Remove redefinitions of a_magic, etc, no longer used.
2117 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
2118 Fix global overview comments to match symfile.c protocol.
2119 (mipscoff_new_init): Eliminate cur_hdr if we have one.
2120 (mipscoff_symfile_read): Eliminate unused code. Avoid
2121 sorting all the symtabs, when all we have read here is psymtabs.
2122 The symtabs are sorted as they are created anyway. Tell
2123 condense_misc_bunches whether we're mainline.
2124 (psymtab_to_symtab_1): Pass filename when recursing, to make
2125 stack trace more informative.
2126 (parse_partial_symbols): Assume cur_hdr as argument.
2127 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
2128 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
2129 the TYPE_NAME of char *, since that's done in symfile.c.
2130 (free_numargs, parse_symbol, add_symbol, add_block,
2131 shrink_linetable): Declare these fns void.
2132 (upgrade_type): Convert tree of if's to switch. Clean up
2133 bogus "off == 0" handling with a complaint. Avoid setting
2134 field bitpos and bitsize of array with lower and upper bounds.
2135 Check specified bitsize of elements against their actual type's
2136 bitsize, and complain if different. Complain about unknown
2137 type qualifiers.
2138 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
2139 (psymtab_to_symtab_1): Print names of subsidiary files that
2140 are being read in. FIXME, we read far too many files. This code
2141 is not the problem, the problem is in parse_fdr where the psymtabs
2142 are set up.
2143 (cross_ref): Result should indicate that we used one aux entry
2144 normally, or two if we encountered a "next" entry. This used
2145 to leave the caller pointing at the wrong aux entry.
2146 (add_symbol): If overflowed cur_block, reallocate it larger,
2147 chase all pointers to it, and complain(), rather than clobber memory.
2148 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
2149 (new_field): Only allocate one field initially, not two.
2150 Pull ++ out of macro argument. Simplify.
2151 (_initialize_mipsread): Avoid initialization of importd
2152 global_psymbols and static_psymbols.
2153
2154 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
2155 to properly set pst->symtab; avoid searching for it.
2156 (symfile_fns): Improve comments, add a FIXME.
2157 * dbxread.c: Update comments to reflect symfile protocol.
2158 (read_ofile_symtab, end_symtab): Return the symtab.
2159 (psymtab_to_symtab_1): Set pst->symtab.
2160
2161 * coffread.c (coff_symfile_read): tell condense_misc_bunches
2162 whether we're mainline.
2163
2164 * symfile.h (sym_fns): Remove unused sym_discard member.
2165 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
2166
2167 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
2168 the environment variable is not.
2169 * infcmd.c (finish_command): Use filtered printfs.
2170 * cplus-dem.c: Add struct tags to a few unnamed structs.
2171 * valops.c (value_coerce_array): Improve comments.
2172 * valprint.c (type_print_varspec_suffix): Print array size only
2173 if greater than zero.
2174 * m88k-tdep.c: Shift some lines left by one space, that had
2175 apparently been trashed at some point.
2176 * TODO: More things to do, a few got done.
2177
2178 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2179
2180 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
2181 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
2182 comments.
2183 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
2184 * expread.y, findvar.c, symmisc.c: Ditto.
2185 * printcmd.c (address_info): Update printed forms of LOC_
2186 symbols. Elim LOC_EXTERNAL.
2187 (print_frame_args): Keep track of param stack offsets before
2188 re-looking up to find the local register param is kept in.
2189
2190 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
2191 Further integration of mipsread into gdb. Eliminate unused
2192 routines, duplicate declarations. Handle static symbols in
2193 psymtabs as well as external symbols. When reading symtabs,
2194 insert symbols into the correct block (global, static, or a local
2195 block).
2196 (read_mips_symtab, parse_partial_symbols): Don't pass useless
2197 "incremental" arg.
2198 (mipscoff_symfile_read): Don't call select_source_symtab.
2199 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
2200 rather than SYMBOL_VALUE.
2201 (parse_external): Comment clobbering of top_stack.
2202 (parse_partial_symbols): Update comments. Allocate and parse
2203 static symbols as well as external symbols. FIXME, enum values
2204 are not handled in this pass, but should be. Inline new_psymbol.
2205 Use SYMBOL_VALUE_ADDRESS.
2206 (psymtab_to_symtab_1): Read symbols into global static block
2207 by default (until enter some function's local block context).
2208 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
2209 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
2210
2211 * source.c (select_source_symtab): Select a source symtab
2212 from either the symtabs or, failing that, the psymtabs.
2213 (list_command): Update error message.
2214 (forward_search_command, reverse_search_command): Use getc, not
2215 fgetc, for speed. FIXME, add comment about buffers that die if
2216 overrun by long line.
2217
2218 * values.c (unpack_field_as_long, modify_field): Avoid shifting
2219 by an entire word, which is not portable, if we have a 32-bit
2220 field. (Code in dbxread.c already turns such bitfields, if
2221 aligned, into ordinary ints, but fixing this will help for other
2222 symbol formats and for future changes.)
2223 * core.c (core_open): Handle ANSI const brain death.
2224 * utils.c (vprintf): Fix varargs typo.
2225
2226 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
2227
2228 * findvar.c (find_var_value): Handle &function better.
2229 * TODO: Document work needed on &fn and &array.
2230 * printcmd.c (print_address_symbolic): New arg is the prefix
2231 to print if a name is printed.
2232 (print_address_demangle): Honor "set print address" now.
2233 Use new arg above to improve spacing of output.
2234 * valprint.c (val_print): When printing function pointers,
2235 print symbolic form too.
2236 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
2237
2238 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2239
2240 * core.c (memory_error): Reword error msg to mislead less.
2241
2242 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
2243
2244 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
2245 parse_partial_symbols): Use newer BFD internals (external_filehdr
2246 and external_aouthdr), byte-swap the fields that we care about
2247 before using them, and make the file header data local to
2248 read_the_mips_symtab rather than global.
2249
2250 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
2251
2252 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
2253 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
2254
2255 * main.c (command_line_input): Flush stdout and stderr
2256 before every call to readline. This reportedly fixes a bug
2257 that comes up in Sys V running emacs-gdb and/or xxgdb,
2258 when stdin/out are pipes or sockets.
2259
2260 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2261
2262 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
2263 Avoid declaring Makefile dependencies, because GNU Make stupidly
2264 tries to update it if we do.
2265
2266 * coffread.c: Revise for minor changes to bfd internal coff
2267 indexes.
2268
2269 * configure: If -template= is given a relative path, make it
2270 absolute before recurring in subdirectories.
2271
2272 * configure, configure.in, Makefile.in: Install "configure" script
2273 as replacement for config.gdb.
2274 * config.gdb, Makefile.dist, Makefile.sdir: Remove
2275 * README: Update for configure, mostly. FIXME.
2276
2277 * Add dec3100 as equivalent to littlemips. Indicate in all host &
2278 target config files that they are for the host. When the lines
2279 get copied into the Makefile, this makes it more obvious what's
2280 up.
2281
2282 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2283
2284 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
2285 tabs, which end up in the disassembler output inadvertently.
2286
2287 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
2288
2289 Make it compile cleanly in an ANSI GCC2 environment.
2290
2291 * blockframe.c: <stdio.h>
2292 * cplus-dem.c: free takes a void *, ifdef __STDC__
2293 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
2294 LONG_MAX/radix.
2295 * defs.h (alloca): Avoid doing anything if alloca already def'd.
2296 * stddef.h, stdlib.h: Remove these files.
2297 * symtab.c: Avoid declaring qsort, close.
2298 * symfile.c: Avoid declaring close.
2299 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
2300 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
2301
2302 Assorted other changes.
2303 * dbxread.c: include "libaout.h", not "liba.out.h".
2304 * printcmd.c (print_frame_args): Set recurse properly for
2305 indentation of struct and array parameters.
2306 * valops.c (value_cast): Allow cast to void.
2307 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
2308 single_step() in a target-independent fashion.
2309 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
2310 set up to be ready to continue. This makes us target independent.
2311 * infptrace.c (child_resume): Remove call to single_step; now
2312 can single step a SPARC target of any kind.
2313
2314 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2315
2316 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
2317 docn into separate sections---basically chapters, plus two loose
2318 pieces that can be configured to go in different places. This
2319 allows GNU m4 to preprocess the manual without coredumping.
2320
2321 * Makefile.dist: tell TeX where to find texinfo.
2322
2323 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2324
2325 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
2326 the new target "rdl-apps.texinfo" which captures the Makefile
2327 variable that records where to find the Readline libraries.
2328
2329 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
2330
2331 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
2332 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
2333 * defs.h (const, volatile): Only define if not already defined.
2334 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
2335
2336 * README: Update for release 3.95.
2337 * config.gdb: Don't create readline dir in subdir builds.
2338 * main.c: Include with "..." form for non-system include files,
2339 so "gcc -MM" for "make depend" works.
2340 Include readline files with "...h" rather than <readline/...h>.
2341 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
2342
2343 * coffread.c: Undo minor damage done by Rich Pixley. Use
2344 different internal and external representations of COFF
2345 data structures. Use new BFD routines for swapping them in and
2346 out.
2347 * symfile.c (free_named_symtabs): Avoid freeing file names that
2348 are null or empty. Old i960 tools seem to produce files that
2349 claim to have empty names, causing each successive file read
2350 to blow away the previous one.
2351 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
2352 Move deferred_stores to top of file, but don't separate its
2353 #define's from its variable. Add commentary.
2354 * Makefile.dist: Fix Rich damage; undo "configure" changes in
2355 favor of keeping the (working) config.gdb. Move readline
2356 library up a notch.
2357
2358 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
2359
2360 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
2361 debug info.
2362 * infptrace.c (fetch_registers): no result, since now void.
2363 * tconfig/news: target depends on m68k-tdep too.
2364
2365 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2366
2367 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
2368 gdb.dvi target
2369
2370 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
2371 applied various small fixes due to or inspired by RMS comments
2372
2373 * doc/gdb.texinfo: finished using all RMS comments, save those for
2374 appendices on readline and cmd history (which are in other source
2375 files)
2376
2377 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2378
2379 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
2380 chapter 9; (2) documented 'break' command's menu mode for
2381 overloaded names, in response to hgs problem report C++ p-31
2382
2383 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2384
2385 * doc/gdb.texinfo: (1) better introductory example; (2) more
2386 consistent use of @code, @samp, @file, @kbd throughout; small
2387 cleanups to first three nodes; (3) new "Contributors" node;
2388 (4) Appendix, Renamed Commands; (5) divert specialized startup
2389 instructions to "Targets" chapter for generic manuals, while
2390 leaving them up front for manuals specific to specialized
2391 environments; (6) apply fixes from RMS comments through chapter 4.
2392
2393 * pretex.m4: modify explanatory text slightly (and redefine
2394 "regexp") to keep GNU m4 from complaining. (It still crashes
2395 later, but one step at a time...)
2396
2397 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
2398
2399 * readline/readline.c (update_line): Avoid dereferencing a pointer
2400 before comparing it to its bounds. Saber caught this.
2401 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
2402 and only set PC if tgetstr returned non-null. Saber caught this.
2403
2404 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2405
2406 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
2407 stuff for config manual) here where it counts; updated
2408 to use new subdir structure (gdb/doc/).
2409
2410 * Makefile: generated from above via
2411 config.gdb none
2412 before checkin
2413
2414 * gdbint.texinfo: added instructions on generating gdb.info* files
2415 locally for release. These are ordinary info
2416 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
2417 Makefile)---but due to use of texinfo 2, can't count on makeinfo
2418 to generate these, so we distribute them already formatted.
2419
2420 * gdb.texinfo: included full Info node and menu crud (as generated
2421 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
2422
2423 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
2424 put in comments-for-future gdb.info target (one day makeinfo will
2425 work again).
2426
2427 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2428
2429 * gdb.texinfo: Updated to include new or old undocumented
2430 commands, at least the following (perhaps some others I forgot to
2431 record): info f, info float, info path, info program, info s, info
2432 set, info source, info terminal, info types, info user, set/show
2433 print object.
2434 Also covered all recent GDB command renames for v4.
2435
2436 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2437
2438 * mipsread.c: Rather than keeping count of how many symtabs
2439 and psymtabs we have, for sorting purposes, count them when
2440 we need to sort. This fixes bug in rereading of symbol tables.
2441
2442 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2443
2444 * infcmd.c: renamed "info path" to "show paths"
2445 * gdbrc.tex: documented above.
2446
2447 Wed May 8 04:51:11 1991 John Gilmore (gnu at cygint.cygnus.com)
2448
2449 * remote.c: Fix comments.
2450 * utils.c (error): Force out any pending wrap output.
2451
2452 Sat May 4 11:11:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2453
2454 * Makefile.dist: Roll VERSION to 3.95.
2455 Fix up "saber_gdb" to work again.
2456 * saber.suppress: Update.
2457
2458 * coffread.c, exec.c, infptrace.c, inftarg.c, remote.c, solib.c,
2459 symtab.h, target.c, target.h: Lint.
2460 * core.c: setup and select frame after reading shared libs,
2461 else reading shared libs will clobber them. Lint.
2462 * utils.c (error): Force out any buffered wrap text.
2463
2464 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2465
2466 * remote.c: Remove decls of memory_insert_breakpoint
2467 and memory_remove_breakpoint, no longer used. (Suggestion of
2468 Jan Norden).
2469
2470 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
2471 to make it easier to interface to "configure"'d libraries.
2472
2473 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
2474
2475 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
2476 aliases for set/show print.
2477
2478 Thu May 2 11:22:02 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
2479
2480 * coffread.c (coff_sym_fns) [TDESC]: Make the type be m88kbcs.
2481
2482 * m88k-tdep.c (IEEE_isNAN): New function.
2483

2498
2499 * m88k-pinsn.c (sprint_address): Declare at top of file.
2500
2501 * m88k-xdep.c: #if 0 out core_file_command.
2502
2503 * values.c ({unpack_,value_as_}pointer): Just call
2504 {unpack_,value_as_}long (for now anyway).
2505
2506 * m88k-tdep.c (get_saved_register): Make get_reg a dc_word_t (*)().
2507 (psr_register): Change return type to dc_word_t.
2508
2509 * m88k-tdep.c (tdesc_read_function): Comment out call to ptrace.
2510
2511 * m88k-tdep.c (get_saved_register): Add lvalp parameter.
2512
2513 * gdbcore.h (write_memory): Don't prototype it.
2514
2515 * tm-88k.h, m88k-tdep.c: Make stack_error, stack_jmp global.
2516 m88k-xdep.c: Don't mention stack_error.
2517
2518 * {x,t}config/m88k ({X,T}DEPFILES): Add missing files.
2519
2520 * mtrace.c: Don't typedef things like size_t, just #define them.
2521
2522 * coffread.c [TDESC]: #if 0 out references to coffsyn.
2523
2524 * symtab.h (struct symtab): Include EXTRA_SYMTAB_INFO.
2525 tm-88k.h: Define EXTRA_SYMTAB_INFO.

2528 dc_dcontext_t not int.
2529
2530 * coffread.c [TDESC]: Use system include files not <intel-coff.h>.
2531
2532 * coffread.c [TDESC]: Move setting of debug_info from
2533 coff_symfile_read to find_linenos and make it work with BFD.
2534
2535 * cplus-dem.c [__STDC__]: Make x{m,re}alloc return void*.
2536
2537 * signame.c: Cast const char* to char* when assigning to sys_siglist.
2538
2539 * utils.c (strsave): Make arg const char* not char*.
2540
2541 * infrun.c (wait_for_inferior) [SHIFT_INSN_REGS]: Use
2542 bpstat_explains_signal (stop_bpstat) not stop_breakpoint.
2543
2544 * tm-88k.h (START_INFERIOR_HOOK): Make tdesc_handle a dc_handle_t.
2545
2546 * tm-88k.h (EXTRACT_RETURN_VALUE): Use char * not void *.
2547
2548 * findvar.c (read_var_value, case LOC_CONST_BYTES): Put the address
2549 in a char *, not a CORE_ADDR. Use SYMBOL_VALUE_BYTES.
2550
2551 * tm-88k.h (INIT_EXTRA_FRAME_INFO): Use fci not prev (fci is
2552 prev except from create_new_frame). Make next_frame a
2553 local variable.
2554 Declare get_prev_context.
2555 {x,t}m-88k.h: Enclose USG and BCS defines in #if !defined.
2556 m88k-{opcode.h,pinsn.c,xdep.c,tdep.c}: New files (same contents as
2557 before; they had just been left out of the distribution for a long
2558 time).
2559
2560 Thu May 2 17:53:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2561
2562 Mips bringup and general cleanup
2563
2564 * cplus-dem.c: Move CPLUS_MARKER define to after defs.h.
2565 * infptrace.c (PT_WRITE_D, PT_READ_D): Use correct values.
2566 (This still doesn't seem to make MIPS bkpts work.)
2567 * mipsread.c: Remove dup "Reading symbol data..." msg.
2568 (symbol_file_command, add_file_command): Remove, obsol.
2569 * printcmd.c (ptype_command): Say "an enum" rather than "a enum".
2570 Wrap output appropriately.
2571 * stack.c (locals_info, catch_info, args_info): Check
2572 selected_frame rather than target_has_stack or coredumping.
2573 * valprint.c (type_print_varspec_suffix): Wrap "ptype" output of
2574 enums appropriately.
2575
2576 Wed May 1 14:10:22 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
2577
2578 * signame.c: Include defs.h and param.h.
2579
2580 * cplus-dem.c: Include defs.h and param.h.
2581 Makefile.dist: Don't hack in the "param.h".
2582 param.h: Don't include defs.h.
2583
2584 * expread.y: Use a union to deal with the fact that type_stack
2585 can have both ints and enum type_pieces in it.
2586 ({push,pop}_type_int): New functions.
2587
2588 Tue Apr 30 13:18:58 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
2589
2590 * cplus-dem.c (cplus_mangle_opname): Don't call error.
2591 values.c (check_stub_method): Call error if NULL return from
2592 cplus_mangle_opname.
2593
2594 * blockframe.c, breakpoint.c, core.c, command.c, findvar.c,
2595 eval.c, expprint.c, infcmd.c, infrun.c, main.c, printcmd.c,
2596 remote.c, source.c, stack.c, dbxread.c, coffread.c, symfile.h,

3009 Thu Apr 18 18:08:30 1991 John Gilmore (gnu at cygint.cygnus.com)
3010
3011 * symfile.h (free_named_symtabs): Rename from free_named_symtab.
3012 * symfile.c (clear_symtab_users_once, cashier_psymtab,
3013 free_named_symtabs): Move these routines from symmisc.c.
3014 * symmisc.c (same): same.
3015 (free_symtab): Make non-static.
3016 * symtab.h (free_symtab): Declare as exported void fn now.
3017 * dbxread.c (end_symtab, end_psymtab): Change comments.
3018 (initialize_dbxread): Call dbx_new_init() in case the first
3019 command is add-symbols.
3020 * target.c (dummy_target): Permit add_syms_addr_command.
3021
3022 Sat Apr 13 14:46:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3023
3024 Permit symbols to be superseded when new symbol files have
3025 been read in, particularly for VxWorks.
3026
3027 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
3028 to the main file, as well as to include files. Also, put global
3029 functions into the global psymtab, to make "i fun" work.
3030 (end_psymtab): Free named symtabs and psymtabs for a file, once a
3031 new psymtab for it has been read.
3032 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
3033 a file, once a new symtab has been read for it.
3034 * mipsread.c: FIXME. We need to do the same for MIPS, but it
3035 looks harder to determine the top-level block before it's been
3036 queued to the psymtab list.
3037
3038 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
3039 If we have wiped out any old symbol tables, clean up at end of
3040 symbol reading.
3041 (symbol_file_command): Don't reference symfile_fns if it's zero.
3042
3043 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
3044 defines for the blocks of a blockvector that contain global and
3045 file-static symbols and the first of the smaller scope contours.
3046 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
3047 decode_line_1, make_symbol_completion_list): Use the above.
3048 * coffread.c (end_symtab, patch_opaque_types): Ditto.
3049 * dbxread.c (end_symtab): Ditto.
3050 * expread.y (block): Ditto.
3051 * mipsread.c (throughout): Ditto.
3052 * symmisc.c (free_named_symtabs): Ditto.
3053
3054 * symtab.c (list_symbols): Process the first symbol of the
3055 static psymbols list.
3056 (types_info): Restore this function from its untimely #if 0.
3057 It's not perfect, but it is better than nothing.
3058 (_initialize_symtab): Restore "info types".
3059
3060 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
3061
3062 * m68k-stub.c: Remote stub for 680x0's, created from
3063 rem-m68k.shar (which is removed).
3064 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
3065 Remove RCS log stuff now that we use CVS and it blows our diffs.
3066
3067 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
3068
3069 * symmisc.c (free_named_symtab): Make it work, in its current
3070 kludgy fashion. Change result to indicate if we blew away bkpts.
3071 * dbxread.c (end_symtab): Accumulate result from
3072 free_named_symtab and print warning if we blew user's state.
3073 * symfile.h: free_named_symtab now returns an int.
3074
3075 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
3076
3077 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
3078 is the first symbol read, even if not mainline.
3079 (dbx_psymtab_to_symtab): symfile might be zero, cope.
3080 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
3081 (set_section_command): New command ("section xxx yyy" -- should
3082 be renamed to "set section xxx yyy" FIXME) which sets the
3083 base address of a section of the exec file, overriding the
3084 virtual address that BFD reports.
3085
3086 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
3087
3088 * exec.c: Add add_syms_addr_command to exec_ops, so you can
3089 load symbols at any address while examining an exec file.
3090
3091 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3092
3093 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
3094 for printing the float info is host-dependent, not
3095 target-dependent. FIXME.
3096 * i386-pinsn.c: Move #includes to top, remove useless ones.
3097 * i386-tdep.c: Don't bother including <.../reg.h> since we
3098 don't use it (and it doesn't exist on host systems).
3099
3100 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
3101 Convert negative numbers properly.
3102 (ieee_test): Make numbers really random; fix format arg.
3103
3104 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
3105 * core.c (core_detach): Unpush core_ops, which might not be on
3106 top. We used to just pop the top, which broke things. Don't
3107 need dont_repeat() any more.
3108 (core_file_command): Psst! Don't repeat it.
3109 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
3110 * expprint.c (print_subexp): Avoid switch fallthru on
3111 BINOP_ASSIGN_MODIFY, so we can print += and such.
3112 * frame.h: Fix typo.
3113 * inflow.c (kill_command): After killing inferior, print our
3114 current frame in the core file, if we have one.
3115 (generic_mourn_inferior): When inferior dies, either select
3116 the current frame (in the new target, e.g. core file), or
3117 set both the current and selected frames to NULL.
3118
3119 Changes from Peter Schauer.
3120
3121 * infptrace.c: Avoid <sys/ptrace.h> on USG.
3122
3123 * Make all file names fit in 14 characters (sigh and damn!):
3124 mv hp300hpux-xdep.c hp300ux-xdep.c
3125 mv symmetry-xdep.c symm-xdep.c
3126 mv symmetry-tdep.c symm-tdep.c
3127 mv convex-opcode.h convx-opcode.h
3128 mv tm-vxworks960.h tm-vx960.h
3129 mv tm-vxworks68.h tm-vx68.h
3130 mv Makefile.srcdir Makefile.sdir
3131 mv gdb-int.texinfo gdbint.texinfo
3132 mv remote-sa.m68k.shar rem-m68k.shar
3133 mv remote-multi.shar rem-multi.shar
3134 * Makefile.dist, README, config.gdb, convex-pinsn.c,
3135 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
3136 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
3137 names.
3138
3139 * command.c (user_info_1, user_info): New command for listing
3140 the user-defined commands.
3141
3142 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
3143
3144 * dbxread.c (really_free_pendings): Clear file_symbols
3145 and global_symbols after freeing them; otherwise, running
3146 this function twice (if it appears twice on the cleanup
3147 chain), we try to free things twice.
3148
3149 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
3150 based on text_addr (the address of text in core), not on addr (the
3151 offset between text in the .o file and in core). This change
3152 is from Peter Schauer.
3153
3154 * main.c: Define ALL_CLEANUPS as a cast of zero.
3155 (return_to_top_level): Use it.
3156 (main): Do all cleanups after each command run as part
3157 of the gdb startup sequence. Also do all cleanups before
3158 entering the command loop, and every time we exit the command
3159 loop and reenter. Before, the cleanups from the startup sequence
3160 were being left undone until the first error!
3161 (command_loop): Rename do_nothing cleanup to command_loop_marker
3162 so we can see it easily when examining the cleanup chain.
3163 (init_signals): Add another do_nothing for signal handling.
3164 (quit_command): Only try to kill target if it has execution.
3165 Problems in the target stack got us into a state where
3166 inferior_pid was nonzero but none of the targets had execution.
3167 In this state you couldn't exit gdb.
3168
3169 * dbxread.c: Two changes from Peter Schauer.
3170 (echo_command): Fflush output after an echo command.
3171 (show_history): Pass all args to cmd_show_list.
3172
3173 * utils.c (init_malloc): Call mtrace to turn on tracing
3174 if the environment variable MALLOC_TRACE is set to a file name.
3175 * mtrace.c: Add source file which provides a log of every malloc,
3176 free, and realloc to a trace file.
3177 * mtrace.awk: Add source file which analyzes the trace file.
3178 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
3179 (VERSION): Roll to 3.94.3.
3180
3181 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
3182 (check_duplicates): Don't bother with watchpoints.
3183 (set_raw_breakpoint): Comment about danger of this routine.
3184 (watch_command): Parse and eval all args before calling
3185 set_raw_breakpoint.
3186
3187 * solib.c (find_solib): Avoid error in referencing memory to
3188 see if any more shared libraries have been added. This is
3189 particularly useful if the target has terminated. Bug reported
3190 by Peter Schauer.
3191
3192 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
3193 in bringing up 3.94.2 on the Sun-3.
3194
3195 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
3196 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
3197 expression (in scope) before reenabling watchpoint.
3198 * signame.c (init_sigs): Add missing declaration of i, fix
3199 sys_siglist declaration.
3200 * source.c (list_command): Fixed range computation to use
3201 lines_to_list ().
3202 * stack.c (backtrace_command): Do not allow command if target has
3203 no stack, print informative error message.
3204 * target.c (target_command): Do not write into command line
3205 because this fails if the target command is used in a user defined
3206 command. [This change was enhanced by gnu to support any-
3207 unique-prefix matching on target names.]
3208 * valops.c (value_struct_elt): Avoid infinite loop on an
3209 erroneous attempt to print the member of function (try p main.p).
3210
3211 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3212
3213 * expread.y (name_no_typename): Avoid reduce/reduce errors
3214 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
3215 Since the GDB parser really doesn't use name_no_typename in a
3216 name-only context, the parser can't tell the diff between
3217 names and numbers here. Avoid allowing a name_no_typename
3218 to be a NAME_OR_*INT to resolve the conflict.
3219
3220 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3221
3222 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
3223
3224 * valprint.c (val_print_fields): bitfield printing didn't handle
3225 byte order. Indirect through a few more fns to cope.
3226
3227 * values.c (modify_field): also cope with byte order.
3228
3229 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
3230
3231 Cleanup for release 3.94.2:
3232
3233 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
3234 include files. Roll version to 3.94.2.
3235
3236 * coffread.c (init_stringtab): Read length into unsigned char
3237 array before swapping; don't assume 32-bit longs.
3238
3239 * target.c (target_info): Don't bother with get_sym_file, just use
3240 the symfile global variable.
3241 * symtab.h, symfile.c (get_sym_file): Delete it.
3242
3243 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
3244 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
3245 (read_type): Replace one more error() with complain().
3246
3247 * mipsread.c (parse_partial_symbols): Replace printf with complain.
3248
3249 * i960-tdep.c: Fix copyright attribution.
3250
3251 * config.gdb: Quote all backquotes in doublequotes. You can
3252 quote me on that. BSD 4.4 shell found this one.
3253
3254 * infptrace.c (throughout): The third argument to ptrace is an
3255 int *, not an int.
3256
3257 * infrun.c (wait_for_inferior): When program has terminated, we
3258 have to call target_terminal_ours before we pop that target off
3259 the stack (e.g. before a call to target_kill or
3260 target_mourn_inferior). This fixes problem where a program
3261 terminates, then GDB stops for (tty output) and you have to type
3262 "fg" to the shell to resume it. FIXME: This code for what to
3263 do after termination really should be in normal_stop instead.
3264
3265 * gdbcore.h (read_memory_check): Change declaration; it changed
3266 names months ago.
3267
3268 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
3269 4.4 prereleases, this avoids a bug in their sgtty compatability
3270 support.
3271 * remote.c: Use terminal.h rather than hand-rolling the same.
3272
3273 * signame.c, signame.h (psignal): Arg is unsigned, not int.
3274 * utils.c (strsave, strstr): Fix arg types.
3275 * valprint.c (val_print): lint
3276
3277 MIPS symbol table support from Per Bothner:
3278
3279 * symfile.c (symtab_fns): Remove initializer table that needs to
3280 be hacked for each new symbol file format supported.
3281 (add_symtab_fns): New function, chains symbol table
3282 handlers into the global list.
3283 (symfile_init): Search this list.
3284 * symfile.h: Add next pointer, declare add_symtab_fns.
3285 * coffread.c (_initialize_coffread): Call add_symtab_fns.
3286 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
3287
3288 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
3289 symbol *). Thus, we no longer need the hack to trash
3290 pst->filename. Good, since that hack confused code in symfile.c!
3291
3292 (reorder_symtabs, destroy_all_symtabs): Removed static
3293 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
3294 Instead, the latter now uses a temporary array (stack-allocated
3295 from an obstack, and then freed).
3296
3297 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
3298 haven't been set in the outermost stBlock of a procedure. This was
3299 a problem with f77 binaries on Ultrix 4.?.
3300
3301 (new_symtab, new_symbol, new_type): Continue changing code to use
3302 obstacks more and otherwise conform to dbxread internal style.
3303 Made the free_code of symtabs be free_linetable (as in dbxread)
3304 instead of free_contents. This implies memory leaks when reading
3305 a new symbol table, until the conversion is finished. Did change
3306 (struct symbol) and (struct type) to be allocated on the
3307 symbol_obstack. Blocks and blockvectors are among the things
3308 still "leaking."
3309
3310 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
3311 tested much, but it solved one problem (reported by Meissner), and
3312 cleans up some other things. The problem happened when an
3313 included file contains actual code (functions) and not just
3314 definitions. The mips coff is a little inconvenient there, since
3315 it may cause a procedure to be mapped to the wrong psymtab.
3316
3317 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
3318 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
3319 this will need work for the new core paradigm.
3320
3321 Opcode patches from the net:
3322
3323 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
3324 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
3325 missing altogether - they are added here. From Bruce Bauman.
3326 * mips-opcode.h: The low mask for C0 instructions was too small.
3327 From Garrett Lau. I modified the fix to check the entire 32-bit
3328 opcode.
3329
3330 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
3331 Bauman.
3332
3333 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3334
3335 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
3336
3337 * dbxread.c (read_type): Pointer subtraction (value_sub in
3338 valarith.c) sometimes failed because the types of the
3339 pointers being subtracted were not identical.
3340 These differed because dbxread.c was allocating pointer types
3341 using dbx_alloc_type+smash_to_pointer_type instead of
3342 lookup_pointer_type. I failed to find a justification for the
3343 former, so I changed it to use the latter. Similarly, I
3344 replaced smash_to_function_type by lookup_function_type,
3345 and smash_to_reference_type by lookup_reference_type.
3346
3347 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
3348 _initialize_mipsread): corresponding changes.
3349
3350 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
3351
3352 * source.c (mod_path): Do tilde_expand on each component of the path,
3353 rather than on the (list of) paths as a whole.
3354 (print_source_lines): Set first_line_listed in addition to
3355 current_source_symtab and current_source_line. If the source was
3356 not findable, after a "dir" command to fix the problem,
3357 a "list" would get the wrong lines.
3358
3359 While I was there... (gnu):
3360
3361 * dbxread.c (read_type): Change error to complaint.
3362
3363 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3364
3365 First attempt at detailed understanding of symbol table memory alloc.
3366
3367 * dbxread.c (dbx_symfile_read): Free our string table if we
3368 aren't the mainline. Free the "info" struct since we're done with
3369 it.
3370 (init_psymbol_list): Free any previously allocated psymbol lists.
3371 (): FIXME: Should realloc-down the psymbol lists when done reading
3372 the main symbol file?
3373
3374 * symmisc.c (free_symtab): Free fullname field too.
3375
3376 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
3377 (REGISTER_ADDR): Make result type unsigned int.
3378
3379 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
3380 define REGEX must also define REGEX1 (its dependency).
3381
3382 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
3383
3384 * tconfig/i960: No longer works, points you at vxworks960 or
3385 nindy960.
3386
3387 * xgdb.c, XGDB-README: Remove file. Users can get the much
3388 better xxgdb.
3389 * Makefile.dist: Remove all trace of xgdb.
3390
3391 * breakpoint.c (breakpoint_1): Pass demangle arg to
3392 print_address_symbolic.
3393 (clear_breakpoints): Remove unused function.
3394 (breakpoint_re_set_one): Guts of breakpoint_re_set.
3395 (breakpoint_re_set): Use catch_errors to do them all anyway.
3396
3397 * gdb-int.texinfo (Host versus Target): Add section on what is
3398 a "host" feature versus what is a "target" feature.
3399
3400 * infcmd.c (path_command, path_info): Handle the PATH variable
3401 (object search path) as conveniently as the source search path.
3402 * environ.c (set_in_environ): Set some vars in GDB's environment,
3403 in addition to the child's. PATH, G960BASE, G960BIN for starters.
3404 * source.c (mod_path): New function, from guts of
3405 directory_command, modifies a path. Used by path_command.
3406 (directory_command): Call it.
3407 * defs.h (strsave): Declare.
3408
3409 * utils.c (sevenbit_strings): Add new printing option.
3410 (printchar): Use it.
3411 (strsave): Provide this handy helper routine.
3412 (set_width_command): Rename set_screen_width_command.
3413 (_initialize_utils): "set screen-width" => "set width";
3414 "set screen-height" => "set height"; add sevenbit-strings.
3415
3416 * infcmd.c (do_registers_info): Print floating point registers
3417 in raw hex as well as float format, regardless of whether it is
3418 a "virtual" convertible register.
3419 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
3420 regs as a double, just in case it's being used that way.
3421 * values.c (unpack_long): Comment on array/function coercion.
3422 (unpack_double): Argument is in target byte order now. For
3423 integer arguments, just call unpack_long and float the result.
3424 * m68k-tdep.c: include defs.h for "const" handling.
3425 * remote-nindy.c: Use ieee-float stuff.
3426 (nindy_fetch_registers): Unpack double regs to host double, then
3427 to extended.
3428 (nindy_store_registers): Pack extendeds to host double, flip
3429 around by misusing unpack_double, send as target double.
3430
3431 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
3432 zero, as when stopped at the first instruction of a process.
3433
3434 * blockframe.c: Fix filename in comment (param.h => tm.h).
3435 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
3436 * tm-68k.h: Fix typos.
3437
3438 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
3439
3440 Changes from a bringup on the DEC Vax under Ultrix 4.0.
3441
3442 * coredep.c (fetch_core_registers): Pass end-address of register
3443 section to register_addr as expected. Don't call supply_register
3444 if we'd just pass it garbage.
3445
3446 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
3447
3448 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
3449
3450 * target.c (push_target, target_info): Cast enums to int for < or
3451 > comparison.
3452
3453 * stack.c (print_frame_info): Identify source file & line
3454 even if we can't print it.
3455
3456 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
3457
3458 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
3459
3460 Clean up IEEE floating point support.
3461
3462 * ieee-float.h: New file.
3463 * ieee-float.c: Write real routines to convert between host
3464 doubles and various target IEEE extendeds.
3465 * m68k-xdep.c: Eliminate assembler code for extended floats.
3466 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
3467 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
3468 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
3469 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
3470 double_to_ieee_extended.
3471 * i960-tdep.c: Define ext_format_i960.
3472 * m68k-tdep.c: Define ext_format_68881.
3473 * sparc-tdep.c: Define ext_format_sparc, though unused.
3474 * Makefile.dist (HFILES): Add ieee-float.h.
3475 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
3476 macros.
3477
3478 Obsolete the "coffstrip" program in favor of using BFD's strip.
3479
3480 * nindy-share/coffstrip.c: Remove file.
3481 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
3482 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
3483 * tconfig/nindy960: Remove reference to coffstrip.o.
3484
3485 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
3486
3487 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3488
3489 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
3490 * dbxread.c: Remove static symfile_bfd.
3491 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
3492 it is not used yet.
3493 * inftarg.c (child_detach): Pop the child_ops vector if the
3494 detach is successful.
3495 * remote-nindy.c (nindy_create_inferior): Don't push a new
3496 nindy_ops since nindy uses the same one for execution and memory
3497 examination anyway.
3498 * core.c (core_ops): Use child_attach and child_create_inferior
3499 rather than default attach and create_inferior functions.
3500
3501 Handle floating point registers in core files.
3502
3503 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
3504 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
3505 This version untested since BFD doesn't yet support sun3 core
3506 files.
3507 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
3508 conventions. Fix comments and style. This version has not
3509 been compiled yet, since we have no HP inhouse.
3510 * core.c (get_core_registers): Look for two sections, ".reg"
3511 and ".reg2", and pass both to fetch_core_registers sequentially.
3512
3513 Revise directory path yet again.
3514
3515 * source.c (forget_cached_source_info): Not static any more.
3516 (init_source_path): New default source path is "$cdir:$cwd".
3517 (dir_command): Handle variable arguments ($cdir, $cwd).
3518 (source_info): Print "Compilation directory" rather than
3519 "Originally compiled in" to remind people of $cdir.
3520 (openp): If the path contains $cwd, use current directory.
3521 (open_source_file): If compilation directory is known, replace
3522 first $cdir in path with the compilation directory.
3523 (print_source_lines): Even if we can't print the lines, set the
3524 current symtab and line for future commands like "info source" or
3525 "breakpoint". Also, error message now contains the file name,
3526 line number, and file access error message.
3527 (_initialize_source): Fix help text to describe changes.
3528 * main.c (cd_command): Forget cached source info when we chdir.
3529 * utils.c (strstr): Add simple implementation.
3530
3531 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
3532
3533 * coffread.c (read_one_sym, init_linetable, init_stringtab):
3534 Byte-swap COFF symbol tables if necessary when reading them in.
3535 Use complain() to replace error message in one spot. Needs
3536 corresponding change in bfd/coff-code.h to make some symbol
3537 swapping routines non-static.
3538
3539 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3540
3541 Merge changes from Eirik Fuller, for UTek.
3542
3543 * defs.h (errno): Add declaration.
3544 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
3545 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
3546 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
3547 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
3548 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
3549 declarations of errno.
3550
3551 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
3552
3553 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
3554 <rpc/rpc.h> and <rpc/types.h>.
3555
3556 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
3557
3558 * i960-tdep.c (examine_prologue): Add new argument limit,
3559 which stops the scan at the end of the prologue, or at the PC.
3560 This fixes a problem where it walks down into the code for the
3561 user's statements if that code looks like function prologues.
3562 Mark Fox and I have been bouncing this code back and forth, making
3563 small changes to it. Callers changed to match.
3564
3565 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
3566
3567 Cleanup for gdb-3.94 release final:
3568
3569 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
3570 the .c files from vx-share and nindy-share, from the various
3571 macros, since they are not found via ALLDEPFILES.
3572 (SFILES): Add tm-i960.h.
3573 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
3574 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
3575 in the SUBDIR list.
3576 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
3577 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
3578
3579 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
3580
3581 * am29k-tdep.c: Add contribution line.
3582 (examine_prologue): Cache information about function prologues in
3583 the misc-function-vector to avoid lots of references over the
3584 serial line while examining instructions.
3585
3586 * core.c (core_close): New function made from cleanup_core.
3587
3588 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
3589 remote-vx.c, remote.c, target.c, target.h,
3590 Update target_ops vector to add attach, close, and load entries.
3591 Use add_syms_addr_command, not add_file_addr_command, for
3592 add_file. Break out close routine from existing code.
3593
3594 * dbxread.c (really_free_pendings): Don't free pending_blocks;
3595 they are in an obstack.
3596 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
3597 Lint.
3598 (define_symbol): Add symbol type parameter; change callers;
3599 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
3600 it to influence the symbol class on the i960.
3601 (define_symbol): Swap LOC_CONST's into target byte order.
3602
3603 * exec.c (exec_close): New function.
3604 (exec_file_command): Call it.
3605
3606 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
3607 Fix byte order of frame pointer.
3608 (read_var_value): Result of 0 if var's value can't be found,
3609 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
3610 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
3611 (locate_var_value): Use read_var_value and use its lazy address
3612 as the location of the var's value. Lint.
3613
3614 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
3615 instructions.
3616
3617 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
3618 obsolete Intel versions in favor of vxgdb versions.
3619 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
3620 code dealing with byte order of values, which Intel did in host byte
3621 order rather than gdb-4's target byte order.
3622 (i960_frame_chain_valid): Move to nindy-tdep.c.
3623 (examine_prologue, skip_prologue, frame_find_saved_regs,
3624 frame_args_address, leafproc_return, saved_pc_after_call,
3625 pop_frame): Add vxgdb versions from Mark Fox.
3626 (examine_prologue, frame_struct_result_address): Add code
3627 to deal with the saved value of G13 (struct return address
3628 pointer).
3629 (frame_args_address): Modify Mark's version to prefer the
3630 saved value over the current value in the topmost frame.
3631 Cache result in the frame info to avoid performance hair in
3632 callers.
3633 (print_fault): Add gdb960 code for printing faults.
3634 (_initialize_i960): Actually call check_host.
3635
3636 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
3637 add stub routines. FIXME, these currently just return zero!
3638
3639 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
3640 (attach_command): Call target_attach, not target_open, now.
3641
3642 * infrun.c (normal_stop): Make global, not static, for vx_attach.
3643 (child_attach): Rename from child_open.
3644 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
3645 don't confuse it with a zero step_resume_break_address.
3646
3647 * inftarg.c (child_detach): Eliminate inferior_pid test.
3648 (child_files_info): Clean up message a bit.
3649 (child_ops): Use child_attach, not child_open, to attach.
3650
3651 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
3652 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
3653 findvar.c to here, since it depends on the contents of the
3654 shadow_contents of breakpoints, but keep if #if 0 since it is
3655 never called.
3656
3657 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
3658 from i960-tdep.c.
3659
3660 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
3661 (ptype_command, display_command): Eliminate have_inferior_p and
3662 have_core_file_p in favor of target_has_stack or
3663 target_has_execution.
3664 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
3665 code for actually finding the values of arguments, though we still
3666 keep track of the maximum stack offset for use in printing unnamed
3667 arguments. Handle missing FRAME_ARGS_ADDRESS.
3668
3669 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
3670 (struct nindy_regs): Define registers passed to/from nindy.
3671 (nindy_fetch_registers, nindy_store-registers): Translate between
3672 nindy and GDB formats for the registers.
3673 (dcache_init): Statically allocate the cache, since it was being
3674 allocated by a malloc that was never freed anyway.
3675 (nindy_create_inferior): Error, not core dump, if no exec file.
3676 (nindy_before_main_loop): Use target_load, not target_add_file.
3677
3678 * remote-vx.c (net_load): Specify large timeout for load
3679 requests. Allow user to break out with INTERRUPT.
3680 (net_break): Remove useless code, clean up. Change callers.
3681 (parse-args, skip_white_space, find_white_space): Clean up arg
3682 parsing to cope with quoted strings.
3683 (net_wait, net_quit): Never call error, just return status.
3684 (vx_read_register, vx_write_register): Cleanup status checking.
3685 #ifdef the code based on which CPU we are using (960 or 68k),
3686 FIXME, this should be completely general but it isn't yet.
3687 (vx_xfer_memory, vx_resume): Cleanup status checking.
3688 (vx_run_files_info): Improve message.
3689 (vx_load_command): Renamed from vx_add_file_command. Allow load
3690 to be interrupted.
3691 (net_ptrace): Remove unused routine.
3692 (vx_wait): Adopt code from vxgdb960 to cope with broken
3693 connections to target machine and prompt to disconnect. Remove
3694 debug printouts. Map some EVENT_'s to SIGnals.
3695 (add_symbol_stub, vx_open): Print names of object files we found,
3696 and "ok" if we read their symbols OK. Clarify output in general.
3697 (vx_attach, vx_detach, vx_kill): Add these commands.
3698 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
3699 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
3700 "info files" output, and create_inferior, since we already have
3701 an inferior.
3702
3703 * stack.c (frame_info): Replace Frame_unknown with 0.
3704 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
3705 (return_command): Pop until the PC matches as well as the FP,
3706 so it works even if the FP is shared with another function,
3707 as in "frameless" or "leaf" procedures.
3708
3709 * symfile.c (load_command): renamed from add_file_target_command.
3710 (add_syms_addr_command): renamed from add_file_addr_command.
3711 (add_syms_command): Stub to call target_add_syms.
3712 (_initialize_symfile): Change command names and descriptions,
3713 add-file => add-syms, and load from alias to its own command.
3714
3715 * target.c (kill_or_be_killed, maybe_kill_then_attach,
3716 maybe_kill_then_create_inferior): Default for attempts to start
3717 a process, if one is already running, is to ask about killing
3718 it and retry if yes.
3719 (upstack_create_inferior): #if-0 it, strata obsolete it.
3720 (push_target, unpush_target, pop_target): to_close() a target
3721 before unstacking it.
3722 (target_info): Renamed from target_files_info.
3723 (_initialize_targets): Rename "i files" as "i target", accessible
3724 under both names.
3725
3726 * target.h: Improve comments about the target_ vectored routines.
3727
3728 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
3729 Convert commenting style to standard GNU style.
3730 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
3731 (SKIP_PROLOGUE): No longer a no-op.
3732 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
3733 (*_REGNUM): Sort register numbers.
3734 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
3735 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
3736 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
3737 are now 10 byte extendeds, not 8 byte doubles.
3738 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
3739 for nindy versus vxworks targets. FIXME, this should possibly go
3740 in the target vector.
3741 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
3742 frame_saved_regs and arg pointer with each frame.
3743 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
3744 (FRAME_ARGS_ADDRESS): Use cached result.
3745 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
3746 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
3747 (PRINT_RAMDON_SIGNAL): Call print_fault.
3748 (POP_FRAME): Now works.
3749
3750 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
3751 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
3752 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
3753 (ADDITIONAL_OPTION_HANDLER): use target_load, not
3754 target_add_file.
3755
3756 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
3757 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
3758
3759 * valarith.c (value_subscripted_rvalue): Avoid handling
3760 floats and doubles specially; it gave alignment errors. Lint.
3761
3762 * valops.c (value_of_variable, value_of_this): Error if unknown
3763 value.
3764
3765 * valprint.c (print_floating): Bcopy rather than pointer-deref,
3766 to avoid alignment problems.
3767 (value_print): Handle unknown value address.
3768 (cplus_val_print): Two args are ignored; remove them. Change caller.
3769 (val_print): Use unpack_long rather than pointer-deref.
3770
3771 * values.c: Lint.
3772 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
3773 to avoid alignment problems.
3774 (value_being_returned): Error if return value unknown.
3775 (set_return_value): Add bogosity warning, FIXME. *
3776
3777 * TODO: A woman's work is never done.
3778
3779 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
3780 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
3781 Add ieee-float.o to OBS.
3782 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
3783 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
3784 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
3785
3786 Changes to generalize the VxWorks RPC protocol slightly, to handle
3787 i960 as well as 68000.
3788
3789 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
3790 * vx-share/reg.h: Produce i960 regs #ifdef I80960
3791 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
3792 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
3793 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
3794 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
3795 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
3796 so they will move in target byte order rather than network
3797 byte order (happens to be the same).
3798
3799 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
3800
3801 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
3802
3803 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
3804
3805 * am29k-pinsn.c,
3806 Add contribution lines to various files, showing where they
3807 came from.
3808
3809 * breakpoint.c (break_insn, check_break_insn_size,
3810 read_memory_nobpt): Remove to mem-break.c.
3811
3812 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
3813 HOST_BYTE_ORDER.
3814
3815 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
3816 entry has bad register number. This change is not
3817 tested in this release, FIXME.
3818
3819 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
3820 tm-vax.h: Ditto.
3821
3822 * value.h: Force value's contents field to be aligned to hold
3823 at least a double or a long long (if supported). This avoids
3824 doing bcopy's in and out of the contents field.
3825
3826 (step_1): Avoid coredump under obscure circumstances when we
3827 have no frame.
3828
3829 * symtab.h (misc_info): Add field to misc function vector for
3830 any kind of cached information the target code desires. AMD
3831 29000 uses this to avoid repeating examine_function_prologue's.
3832
3833 * coffread.c: Lint. Remove static symfile, read_section_header.
3834 core.c (have_core_file_p): Lint: remove.
3835 expprint.c (print_subexp): Lint.
3836 infptrace.c, valops.c, valprint.c: lint.
3837
3838 Roll in changes from vxgdb-5.0.1:
3839
3840 * symtab.h: Comment byte order of each address class. Add
3841 LOC_LOCAL_ARG for frame-relative args (960).
3842 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
3843 symtab.c, symmisc.c: ditto.
3844
3845 * infrun.c (init_wait_for_inferior): Clear stop_signal.
3846
3847 * remote.c (remote_resume): Error if resume with a signal.
3848
3849 * symfile.c (prim_record_misc_function): Clear misc_info.
3850 (fill_in_vptr_fieldno): Check stub type of arg.
3851
3852 * valops.c (value_cast): Avoid looking up names of types whose
3853 name we don't know, to prevent coredump. Sun CC produces typedef
3854 rtx and the name of *rtx is zero...
3855
3856 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3857
3858 Roll in changes from final AMD 29000 port (Tiemann).
3859
3860 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
3861 for ../include/a.out.encap.h. This might not work now that BFD
3862 is separately compiled. Instead, BFD support for encap will have
3863 to translate machine type 29k into the right COFF_MAGIC.
3864
3865 * infcmd.c: Remove references to inferior_pid that aren't used
3866 in actual ptrace calls; use target_has_execution, etc.
3867 (have_inferior_p): Remove function.
3868 (program_info): Print target info rather than "process number";
3869 avoid gratuitous messages unless from_tty.
3870 (run_stack_dummy, finish_command): Set proceed_to_finish.
3871 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
3872 main.c: Lint. Lose have_inferior_p().
3873 inferior.h (have_inferior_p): Remove, lint.
3874 (proceed_to_finish): Add flag to ask that all regs be saved
3875 by normal_stop, for the few commands that need it, speeding up
3876 serial I/O. Add comments to stop_registers.
3877
3878 * remote-eb.c: Remove newline from breakpoint message we grep
3879 for. Never time out when running the user program.
3880
3881
3882
3883 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3884
3885 Roll in changes from vxgdb-5.0.1:
3886
3887 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
3888 symbol in its raw form, we are processing an unlinked ".o" file.
3889 See if the target environment has assigned it an address, using
3890 target_lookup_symbol (VxWorks does), and enter it into the symtab
3891 that way.
3892
3893 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
3894 68k versions for a simpler version that assumes zero FP at bottom.
3895 Fixes bug of truncated stack reports.
3896
3897 * target.h (target_lookup_symbol): Define this routine's args
3898 and result, finally.
3899
3900 * target.c (nosymbol): Default routine for target_lookup_symbol.
3901 (target_default): Default lookup_symbol and call_function too.
3902 (files_info): Only print has_all_memory warning if a non-dummy
3903 target follows.
3904
3905 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
3906 vx_convert_from_virtual): If target does not have floating point,
3907 zero register "values", and avoid doing cross-net conversions.
3908 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
3909 (vx_open): Rearrange code that attaches to target and reads
3910 symbols for all loaded modules, to work if some of the modules
3911 are not accessible. Add symbol_stub() and add_symbol_stub()
3912 as callbacks from catch_errors(). Allow connect attempt to be
3913 interrupted painlessly with ^C (FIXME, there are still some bugs
3914 if the interrupt happens during symbol reading.). Print
3915 final message with puts_filtered, since symbol messages are
3916 now filtered too.
3917
3918 Misc cleanup:
3919
3920 * main.c (catch_errors): Only print errstring if non-null.
3921 (command_loop): Avoid an ioctl per command to test ISATTY.
3922
3923 * remote-vx.c (net_load): make static; avoid sophomoric msg.
3924 (vx_xfer_memory): Return correct result!
3925 (vx_files_info): Indicate whether target has float or not.
3926 (vx_lookup_symbol): Complain, not error, if target gone.
3927 (vx_open): Print "Connected" msg before disabling immediate-quit.
3928 [FIXME: lookup_symbol and vx_open changes need testing.]
3929
3930 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
3931 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
3932 contributor lines and update copyrights to 1991.
3933
3934 Changes from an attempted H-PUX host port:
3935
3936 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
3937 defines PT_ATTACH and PT_DETACH but not PT_KILL.
3938 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
3939 * remote-vx.c: include <sys/time.h> for HPUX.
3940 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
3941 "core_file_command" routine to BFD regime. May not work yet.
3942
3943 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
3944
3945 * xgdb.c: Replace X10 version with some VJ version.
3946 (FIXME: Its copyright assignment is not on record.)
3947 * xgdb.c: Update include files to X11R4 (Xaw crud).
3948 (xgdb_display_source, create_text_widget): fix call to
3949 get_filename_and_charpos. Rewack source window stuff for X11R4
3950 (gleaned from include files, and "nm's" of binary libraries, since
3951 I had no doc available).
3952 (append_selection, append_selection_word): Disable with FIXME
3953 since R4 changed interface here.
3954 (create_buttons): Add back the old set of buttons.
3955 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
3956
3957 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
3958 Roll VERSION to 3.94 (not yet final though).
3959
3960 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3961
3962 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
3963 obstack_int_grow, obstack_int_grow_fast): Eliminate
3964 cast on left of assignment, which gives MIPS cc fits and is
3965 not Standard C.
3966
3967 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
3968 F_ALIAS. Use printf, not fprintf, when not passing a file
3969 pointer...
3970 (compare_opcodes): Check that identical instructions have
3971 identical opcodes, complain otherwise.
3972
3973 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
3974 was reported by Roland McGrath.
3975 (unimp): Only match if exactly zero instruction. (Roland)
3976 (branches and traps): Generate all variations of these
3977 instructions with macros, based on a single call that defines
3978 each condition name and its binary representation.
3979 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
3980
3981 * valprint.c (val_print_fields): Take, and use, format parameter.
3982 This means that "p/x struct" again prints the elements in the
3983 desired format. Changed callers.
3984
3985 * stack.c (frame_info): Use filtered output, and indicate wrap
3986 points. Remove kludgy formatting designed to avoid line wrap.
3987
3988 * utils.c (wrap_here): If the line is already full (because
3989 we had printed a long indent or long wrapped string), do an
3990 immediate newline-and-indent.
3991
3992 * m68k-pinsn.c (print_insn_arg): Bugfix from
3993 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
3994 instruction is incorrectly disassembled as bkpt #8.
3995
3996 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
3997 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
3998 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
3999 and then will dump core (sometimes). I traced it back to an
4000 uninitialized symfile_name in psymtab_to_symtab.
4001 (const_vol_complaint): Add quotes to message.
4002 (define_symbol): Only believe line number if gcc_compiled.
4003 Avoid allocating symbol if we will not return it.
4004
4005 Add target strata support so that newly established targets go
4006 into their right place in the target stack (e.g. a new exec file
4007 doesn't wipe out the ability to access the running process).
4008
4009 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
4010 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
4011 and initialize it properly in all the targets.
4012
4013 * target.h: Document strata. Change return type of push_target.
4014
4015 * target.c (nomemory): new function for dummy memory access.
4016 (tcomplain): Rename complain, now also used in symfile.c.
4017 (push_target): Push targets within strata. New return value shows
4018 whether new target is on top of stack or not. Always keep dummy
4019 target on stack.
4020 (target_files_info): Ignore dummy target.
4021
4022 * core.c (core_open): Warn user, and skip accessing file, if the
4023 core target is not the topmost target in the stack.
4024 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
4025 already handled.
4026
4027 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
4028 target_ops, it doesn't belong there since we have no regs there.
4029 Change name of target from machine => memory to clarify.
4030
4031 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
4032
4033 * Freeze version 3.93 for release.
4034
4035 * Makefile.dist: Handle vx-share and nindy-share subdirs
4036 properly when building gdb.tar.Z.
4037
4038 * symtab.c: lint; add no_symtab_msg to consolidate the messages
4039 printed in various places, so I could change just one copy.
4040
4041 * dbxread.c, coffread.c: Change references to bfd->iostream
4042 to cast to FILE *, now that BFD avoids needing types defined
4043 in other header files.
4044
4045 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
4046
4047 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
4048 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
4049 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
4050 (actually gcc -Wall).
4051
4052 * dbxread.c: Remove first_global_sym, last_global_sym, since
4053 they are never referenced.
4054
4055 * defs.h (baud_rate): Declare.
4056 main.c: Define it, and add the -b option to set it.
4057
4058 * gdb-int.texinfo: Add text on how to define a new host or target
4059 architecture, prompted by Per Bothner's questions about MIPS
4060 support.
4061
4062 * gdb.texinfo: Document "complaints". Change doc of -q since
4063 gdb no longer prints the copyright and blurb if you specify a file
4064 name to be debugged (just like Emacs). Add doc for Nindy-specific
4065 command line flags for specifying target serial port and such.
4066 Update copyright to 1991.
4067
4068 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
4069 has taken over for us the job of ripping up executable files. The
4070 crud caused Per Bothner's port to not compile.
4071
4072 * infrun.c (normal_stop): Avoid printing "Program exited
4073 normally" if we are in batch mode. This allows a GDB which
4074 executes a program on a target system, to behave like a Unix
4075 command (input from stdin, output to stdout, no extraneous
4076 output).
4077
4078 * main.c (main): Allow additional machine-dependent command line
4079 options to be specified with the ADDITIONAL_OPTIONS,
4080 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
4081 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
4082 processing to occur just before the main loop with
4083 BEFORE_MAIN_LOOP_HOOK.
4084 (main): If a "core file" argument is specified, and it is not a
4085 core file, try it as a process ID to attach.
4086 (symbol_completion_function): Attempt to cope with
4087 "show screen-" TAB, not very successfully. This needs more work,
4088 FIXME.
4089 (batch_file): New function, returns whether we are reading
4090 commands from an interactive tty on stdin, or from somewhere else.
4091 Called by normal_stop since it doesn't get from_tty passed down
4092 to it like many commands do.
4093
4094 * remote-nindy.c: Handle command line options for nindy
4095 connection.
4096 (nindy_before_main_loop): Prompt user for tty name if they
4097 don't specify it before getting to the interactive command loop.
4098
4099 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
4100 and -r command line options. Also add hook before main loop
4101 to make it easy to specify a tty.
4102
4103 * TODO: More things to do, one done.
4104
4105 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
4106
4107 * dbxread.c: Make complaint() calls pass pointer, not struct.
4108 Add complaints about badly formatted C++ type information
4109 (const/volatile indicator, and parse errors resulting in
4110 error_type). Fix C++ virtual member fn comment.
4111 (read_struct_type): Avoid bumping pointer if we got a parse
4112 error; this prevents our walking beyond the end of a string.
4113 Terminate loop on null char as well as semicolon.
4114 (process_one_symbol): Fix the LBRAC fix so that it uses the
4115 last previous SLINE, FUN, or SO record's PC address. C++ debug
4116 symbols did not have SLINE records in a useful order compared
4117 to the LBRAC records.
4118 (define_symbol): Handle "catch" records.
4119
4120 * symtab.c (check_stub_type): Added new complain
4121 `stub_noname_complain' and added a consistency check to
4122 keep the debugger from crashing when finishing from an
4123 exception frame. A real fix will be needed later.
4124
4125 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
4126
4127 * infcmd.c (attach_command): Make global.
4128
4129 * Makefile.dist (REMOTE_OBS): Make these compile by default,
4130 but make them easy to comment out. Perhaps later they should
4131 be enabled by what CPU you configure for? FIXME.
4132 (VERSION): Roll to 3.93.
4133 (pinsn.o): Remove rule for obsolete file.
4134 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
4135
4136 Run down a problem that manifested by printing the wrong function
4137 name in stack traces of read_ofile_symtab. Turned out that the
4138 problem was the SunOS 4.1.1 (and previous) C compiler outputs
4139 the LBRAC symbol with an address in the *data* segment, which
4140 blew our binary search through the blocks.
4141
4142 * dbxread.c: Use the complain() facility consistently to bitch
4143 about problems in the symbol file we are reading.
4144 (finish_block): Add code to check the nesting of the blocks;
4145 complain and Procrust them to fit if wrong.
4146 (make_blockvector): Check the order of the blocks, complain
4147 [but don't cope] if wrong.
4148 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
4149 symbols to be sure their PC value is greater than the last SLINE
4150 (line number) symbol we've seen, complaining and adopting the
4151 SLINE PC value if wrong.
4152
4153 * symfile.h (struct complaint, complaint_root, complain,
4154 clear_complaints): Add.
4155 * symfile.c (complain, complaint_root, clear_complaints): Add
4156 facility to deal with non-fatal complaints and to regularize their
4157 suppression.
4158 (symbol_file_add): Clear complaint counters to allow new complaints.
4159 (initialize_symfile): Add 'set complaints' and 'show complaints'.
4160
4161 * dbxread.c (dbx_symfile_read): Remember the address and size
4162 of the string table for the main symbol file, so we won't read it
4163 more than once.
4164 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
4165 to avoid reading the string table yet again. Lint.
4166 (throughout): Improve filtered output, including word wrap.
4167 (read_range_type): Improve Bothner's fix to handle other types too.
4168
4169 * utils.c: Improve line wrap implementation. Handle unlimited
4170 width by making chars_per_line unsigned.
4171 (puts_filtered): New, easy, function.
4172
4173 * defs.h (puts_filtered): add.
4174
4175 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
4176 call the identical sort_symtab_syms() in symfile.c instead.
4177
4178 * expread.y: Suggest the `file' command rather than `symbol-file'.
4179
4180 * command.h (enum var_types): Add zinteger for seroable
4181 unsigned integer.
4182 * command.c (do_setshow_command): Handle var_zinteger. Restructure
4183 nested if's into a switch.
4184
4185 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
4186 we did not stop because of a breakpoint (it must have been for
4187 some other reason, like a "stepi"), so don't print anything.
4188
4189 * symtab.c: Include <sys/types.h> all the time. Now that BFD
4190 doesn't include <sys/types.h>, old SunOS's require it for
4191 <sys/stat.h>.
4192
4193 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
4194
4195 A test port of gdb-3.92.6 to the Sony NEWS.
4196
4197 * Makefile.dist
4198 Don't normally link in remote- or vx stuff.
4199 Some of it doesn't compile, and it wastes space for 99% of the users.
4200 Remove reference to no-longer-used HAVE_VPRINTF.
4201 Fixed BFD_DEP typo to BFD_DIR.
4202 * dbxread.c
4203 Fix cast in arg to bfd_h_getlong.
4204 Make char *prefix be const.
4205 Fix how certain range types are mapped into builtin unsigned int types.
4206 * infrun.c
4207 Remove 2 #includes. They cause errors (on Sony, at least),
4208 and aren't needed (they wern't in earlier versions).
4209 * printcmd.c
4210 print_address_symbolic should never demangle labels
4211 (since it prints *assembler-level* labels).
4212
4213 [This was superseded by the change to printcmd below.]
4214
4215 * utils.c
4216 Add some "volatile" return types to avoid warnings.
4217 If MISSING_VPRINTF add vprintf function and not just macro
4218 (since vprintf is used in printcmd.c).
4219 * valprint.c
4220 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
4221 (The latter isn't grokked by some PCC-based compilers.)
4222
4223 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
4224
4225 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
4226 * nindy-share/coffstrip.c
4227 Added some forward declarations (otherwise, gcc complains
4228 about implicit extern redefined as static).
4229
4230 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
4231
4232 Changes inspired by Per Bothner:
4233 * printcmd.c (print_address_symbolic): Take additional parameter
4234 specifying whether to demangle.
4235 (print_address): Pass in asm_demangle to control demangling.
4236 (print_address_demangle): New fn, takes explicit arg to control
4237 demangling.
4238 * utils.c: Add new vars demangle and asm_demangle, and let them
4239 be set and shown.
4240 (fputs_demangled): If !demangle, just print the argument.
4241 (fprint_symbol): If !demangle, just print raw symbol.
4242 * valprint.c (val_print): Call print_address_demangle rather than
4243 print_address, to cause demangling to depend on the global
4244 rather than assembler-level demangling setting.
4245 * WHATS.NEW, gdb.texinfo: Document.
4246
4247 * main.c (show_command): Show all settings if no arg.
4248 (initialize_main): Make "info set" the same as naked "show".
4249 * command.c (cmd_show_list): Handle prefix commands in the
4250 list, and print the name of the setting as well as its English
4251 description and value.
4252
4253 Allow gdb functions to specify where a line should wrap if it
4254 exceeds the size of a terminal line. Use it to make the output
4255 prettier.
4256 * utils.c (set_screen_width_command): New fn, mallocs a buffer
4257 of the right size when screen width changes.
4258 (set_screensize_command, screensize_info): Remove #if 0'd fns.
4259 (wrap_here): New fn, indicates a point in the output where we
4260 should wrap the line rather than just letting it overflow at a
4261 random place.
4262 (fputs_filtered): Implement wrapping.
4263 (n_spaces): New fn, returns a pointer to N spaces.
4264 (print_spaces_filtered): Use n_spaces.
4265 * defs.h (n_spaces): Declare.
4266 * stack.c (print_frame_info): Wrap with 4-space indent after
4267 fn name and before filename and line number.
4268 * printcmd.c (print_frame_args): Wrap with 4-space indent
4269 before each argument name is printed.
4270 * valprint.c (value_print): Wrap with no indentation before
4271 each repetition.
4272 (val_print_fields): Wrap with indentation relative to nesting
4273 level before each field name.
4274 (val_print): Wrap with nesting indentation before array elements.
4275 * command.c (do_setshow_command): Avoid extra newlines,
4276 wrap with 4-space indent around values printed, end with period.
4277 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
4278
4279 * breakpoint.c (breakpoint_1): Implement addressprint for
4280 "info breakpoints" display. Change file name and line number
4281 format to " at file:nnn" rather than " (file line nnn)".
4282 * gdb.texinfo: Document.

4287 Frozen for gdb-3.92.6 release.
4288
4289 README, WHATS.NEW: Update for 3.92.6 release.
4290
4291 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
4292 coffread.o from configs since it is now built by default.
4293 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
4294 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
4295 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
4296 from configs since it is now built by default.
4297
4298 Makefile.dist: Update for release 3.92.6. Handle files that
4299 have been moved to ../include, ../getopt, or ../bfd. Add
4300 saber.suppress and tests directory. Add config.status to
4301 the release (it will say "none").
4302
4303 coredep.c: Minor formatting fixes.
4304
4305 These changes were made in early December but only checked in now:
4306 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
4307 nindy-share/nindy.c: lint
4308 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
4309 register values coming back from the target; we store values
4310 in target byte order everywhere.
4311
4312 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
4313
4314 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
4315
4316 * valprint.c (cplus_val_print, val_print_fields): New functions,
4317 which print C++ objects. They conspire to avoid printing a
4318 virtual base class more than once, following all the twists and
4319 turns of C++ virtual base rules.
4320 (val_print): Call the above rather than do it by hand.
4321
4322 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
4323 symbol file, not for added files like shared libs. This really
4324 needs to be generalized to a timestamp per file.
4325
4326 * core.c (cleanup_core): Avoid coredump if no core file.
4327
4328 * config.gdb: Accept -host or -target in place of +host or
4329 +target.
4330
4331 * coffread.c (find_linenos): Avoid desupported BFD interface
4332 to line numbers. We still read them manually rather than using
4333 BFD's "generic" features.
4334
4335 * gdbrc.tex, threecol.tex: Add GDB reference card and its
4336 formatting code.
4337 Makefile.dist: Add refcard to OTHERS list for creating tar files.
4338
4339 * Makefile.dist: Eliminate use of $< in explicit targets.
4340
4341 * readline/Makefile: Use $< rather than $*.c, which does not
4342 include the VPATH in GNU Make.
4343
4344 * tconfig/i960-bout, tconfig/i960-coff: These are identical
4345 copies of tconfig/i960, added for global configuration
4346 compatability. All i960 versions can read both coff and b.out.
4347
4348 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
4349 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
4350 automaticaly.
4351
4352 * TODO: Think of more things to do.
4353
4354 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
4355
4356 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
4357 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
4358 64-bit float conversion.
4359
4360 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
4361 equivalent to sun?os4 so global config works.
4362
4363 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
4364
4365 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
4366
4367 * main.c: Only declare linesize once; declare pagesize not at
4368 all, since it is never used.
4369 (main): Clear newly allocated line before it is used.
4370
4371 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
4372
4373 Further stabilization for the Intel 960.
4374
4375 * Makefile.dist: Parameterize the location of the "include"
4376 and "bfd" directories, as well as "getopt". Add symfile.c.
4377 Link in both dbxread and coffread. Fix up "make depend" to
4378 rewack the locations of include, bfd, and getopt in its output.
4379
4380 * README: Document moving include files, improve some of
4381 the other doc.
4382
4383 * coffread.c: Move common code out to symfile.c. Change
4384 symbol_file_command style interface to use new *_symfile_init
4385 and *_symfile_read interface under BFD. Use BFD internal
4386 info to locate line table, symbols, etc.
4387
4388 * core.c (core_fetch_registers): Rename to get_core_registers
4389 to avoid confusion with fetch_core_registers.
4390 (register_addr): Move to coredep.c, which is already machine
4391 dependent. This leaves core.c pretty clean of dependencies.
4392
4393 * coredep.c (register_addr): Accept this routine from core.c.
4394
4395 * dbxread.c: Move common code (with coffread.c, etc) into new
4396 symfile.c. Each psymtab now contains a pointer to the
4397 format-dependent function that knows how to read it in. Make
4398 some things static.
4399 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
4400 (process_one_symbol): Add code to complain about a "compiler bug
4401 we muzzle here", if we actually see it.
4402
4403 * eval.c (evaluate_subexp): Insert missing "break" statements
4404 in code that determines whether a variable is an lvalue in
4405 memory, register, or whatever. I detected this via a compiler
4406 bug in which it *almost* mashed out the whole switch statement.
4407
4408 * gdb-int.texinfo: Add minor sections on configuring gdb for
4409 release, and about the README file.
4410
4411 * infcmd.c (registers_info): Fix formatting somewhat. Still
4412 not as pretty as before, but it handles byte swapping.
4413
4414 * remote-nindy.c: If data cache routines are interrupted while
4415 waiting for the remote end, be sure that any uninitialized cache
4416 blocks are on the free list, not on the valid list!
4417
4418 * symfile.h: Flesh out this header file with all the various
4419 routines and variables that have been merged in from dbxread.c
4420 coffread.c, and symtab.c to symfile.c.
4421
4422 * symfile.c: New file, containing code common to dbxread.c,
4423 coffread.c, and some code from symtab.c. All generic code for
4424 reading symbol files should be in here now.
4425 (unrecord_misc_function): Remove unused function.
4426
4427 * symtab.h: Remove file-reading things to symfile.h.
4428
4429 * symtab.c: Remove file-reading things to symfile.c.
4430
4431 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
4432 to decode i960 fault types.
4433
4434 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
4435 target.c: Change type of the "resume" function from int to void,
4436 since its result was never used.
4437
4438 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
4439
4440 * main.c: Replace "stupid" with "caution"; you now "set caution
4441 on or off".
4442
4443 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
4444
4445 * infcmd.c (do_registers_info): Call val_print to deal with the
4446 byte order of the registers being printed. FIXME, this makes
4447 the formatting of the output uglier.
4448
4449 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
4450 defined, call it for signals the debugger doesn't itself use.
4451 The i960 uses this for more detailed fault information.
4452
4453 * remote.c (remote_open): If arg is null, print help rather than
4454 dumping core.
4455
4456 * sparc-xdep.c (register_valid): Avoid declaring size, since
4457 various modules will think of various sizes depending on the
4458 architecture of their tm-file. FIXME, we need protection against
4459 actually entering one of those modules, which would clobber
4460 storage if not for the target architecture compiled into gdb.
4461
4462 * stack.c (up_command, down_command): Always print the frame
4463 you arrive at.
4464 (up_silently_command, down_silently_command): New commands
4465 for use in scripts.
4466
4467 * i960-pinsn.c (reg), i960-tdep.c: Lint.
4468
4469 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
4470 more parameters than it used to.
4471
4472 * findvar.c (registers): Increase slop to 256 bytes, which should
4473 protect us against even most RISC machines with large register
4474 sets.
4475 (locate_var_value): Move declaration inside related ifdef.
4476
4477 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
4478 throughout, to avoid throwing away buffered input from the board.
4479 (nindy_wait): Supply_register takes addr_of_value, not value.
4480 (i960_print_fault): Renamed from i80960_fault.
4481 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
4482 (nindy_store_registers): Avoid regs_changed stuff, just stuff
4483 them.
4484 (nindy_create_inferior): Don't bother to write PC_REGNUM since
4485 we can set the PC in the call to proceed(). Unpush nindy_ops
4486 before pushing it on top, to avoid message to user. Eliminate
4487 commentary from Unix machines that just misleads here.
4488 (reset_command): Fix error message to suggest target command.
4489
4490 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
4491
4492 Release 3.92.5 as frozen.
4493
4494 Stabilize the merged release...with help from lint, Saber C,
4495 gcc -W, etc.
4496
4497 Everywhere: Add include files needed to declare return types
4498 of functions called.
4499
4500 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
4501
4502 * breakpoint.h: Add undeclared breakpoint functions, and some
4503 functions for display handling since I couldn't think of a better
4504 .h to put them in.
4505
4506 * breakpoint.c (insert_breakpoints): Make code for disabling
4507 shared library bkpts more likely to work. It's used when we
4508 rerun a program and stop before the shared library has been
4509 mapped in.
4510 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
4511 cast from pointer, so it squeezes through catch_errors.
4512 (bpstat_stop_status): Fix logic broken some time ago. We now
4513 always create a bpstat if the stop address matches a breakpoint,
4514 even if we don't stop there -- just like the old code used to do
4515 before I got my fingers into it (sigh).
4516 (breakpoint_1): Print "ignore count" after "stop only if"
4517 condition, since that's how it actually works.
4518 (mention): Handle watchpoints as well as breakpoints.
4519 (watch_command): use set_raw_breakpoint and mention to do most
4520 of the work (and initialize all the fields!). Only pass one
4521 arg to parse_c_expression, since that's all it takes.
4522
4523 * command.c (not_just_help_class_command): Rename arg to args
4524 since we ignore "unused argument" warnings on vars named "args".
4525 inflow.c (child_terminal_info): ditto.
4526 infptrace.c (kill_inferior): ditto
4527 main.c (catch_errors, version_info, quit_command, pwd_command,
4528 source_command, dump_me_command, editing_info,
4529 set_history_size_command, set_history, show_history,
4530 set_verbose): ditto
4531 stack.c (locals_info): ditto
4532 target.c (target_files_info): ditto
4533 valprint.c (set_input_radix, set_output_radix): ditto
4534
4535 * core.c: Remove old variables for handling core and exec file
4536 sections (data_start, data_end, stack_start, stack_end,
4537 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
4538 text_end, exec_data_start, exec_data_end, text_offset,
4539 exec_data_offset, data_offset, stack_offset). They're
4540 superseded the more general build_section_table and
4541 xfer_memory.
4542 (get_exec_file): Mention the `file' command.
4543 (read_memory_check): Rename to memory_error, and only call it
4544 in the case of an actual error.
4545 (read_memory, write_memory): call memory_error.
4546 (core_fetch_registers): Register section name is ".reg".
4547
4548 coredep.c: Remove a bunch of crud now that all this file does
4549 is pull the registers out of a core file.
4550 (fetch_core_registers): Rewrite to actually work, I hope.
4551
4552 dbxread.c: Use a.out.gnu.h, not system a.out, now.
4553 Replace index() with strchr(). Remove all the pre-BFD macro
4554 definitions for accessing the symbol file.
4555 (struct dbx_symfile_info): Encapsulate the information that
4556 dbx_symfile_init needs to pass to dbx_symfile_read in this
4557 struct.
4558
4559 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
4560 dbx_symfile_discard): Rearrange symbol file reading to divide
4561 the format-specific part from the format-independent part,
4562 leaving the format-independent part such as file name expansion
4563 and opening in symtab.c. This replaces
4564 partial_symbol_file_open and partial_symbol_file_read.
4565 Symbol_file_read, add_file, add_file_target_command,
4566 add_file_addr_command move to symtab.c. Pass an explicit
4567 "mainline" flag for when reading the main symbol table, rather
4568 than relying on the offset address to be zero or nonzero.
4569
4570 (dbx_symfile_read): Don't allow void *'s to be printed as
4571 typedefs.
4572 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
4573 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
4574 macro" debug version really work.
4575 (read_dbx_symtab): Remove unref'd parameter inclink.
4576 Avoid swapping N_SLINE symbols, for speed.
4577 Merge N_TEXT!N_EXT case with the other external symbol
4578 definitions' case. Add comments.
4579 (start_psymtab): Allocate the symfile name in the psymtab on
4580 the psymbol_obstack, rather than using the caller's storage.
4581 (end_psymtab): Only allocate a dependencies list if there are
4582 more than zero.
4583 (psymtab_to_symtab_2): Use BFD when reopening file to read
4584 its symbols for real.
4585 (read_struct_type): Add FIXME comments where it needs work
4586 for C++ bogosity.
4587 (read_huge_number): Add FIXME about overflows.
4588 (read_range_type): Add FIXME about comparing a long to 1<<32.
4589
4590 * coffread.c: Minor changes to move things closer to the new
4591 regime with symtab.c and dbxread.c Major work is still needed
4592 here.
4593
4594 * exec.c (exec_file_command): Remove old variables (see core.c
4595 above).
4596 (xfer_memory): If memory transfer is right at the end of a
4597 section, don't lose.
4598
4599 * findvar.c (get_saved_register): If value is in a real
4600 register, LVAL is lval_register, not lval_memory.
4601
4602 frame.h: Declare print_sel_frame and record_selected_frame.
4603
4604 gdb-int.texinfo: New file, for GDB internals documentation.
4605 Very simple, unformatted doc of cleanups is there for now.
4606
4607 gdbcore.h: Remove obsolete variables that described a.out
4608 section addresses and offsets. (See core.c above.)
4609 Declare fetch_core_registers and registers_fetched.
4610
4611 getopt.c: Declare char *alloca(); even on SPARC.
4612
4613 infcmd.c (run_command): Call target_kill rather than
4614 kill_inferior.
4615 (step_command, next_command, stepi_command, nexti_command):
4616 Declare from_tty parameter even though we don't use it.
4617 (run_stack_dummy): argument BUFFER is a char array, not
4618 a pointer to REGISTER_TYPE.
4619 (finish_command): using_struct_return needed a value *,
4620 not a struct symbol *.
4621
4622 * infptrace.c (child_xfer_memory): To avoid dependency on
4623 where sections are in memory, try PT_WRITE_D and if that fails,
4624 try PT_WRITE_I. Most Unixes don't care which you use.
4625
4626 * infrun.c (step_resume_break_shadow): Change to array to
4627 match other breakpoint shadow storage.
4628 (clear_proceed_status): Pass address of bpstat to
4629 bpstat_clear, not the bpstat itself.
4630 (child_create_inferior): FIXME comment about if the child
4631 exits.
4632 (start_inferior): Remove old function.
4633 (child_open): Use target_kill rather than kill_inferior.
4634 (wait_for_inferior): Ditto.
4635 (insert_step_breakpoint, remote_step_breakpoint): Use
4636 new step_resume_break_shadow.
4637
4638 * inftarg.c (child_wait): If all child processes die,
4639 pretend that the one being waited for exited with signal 42.
4640
4641 * main.c (command_line_input): When scanning for comments,
4642 don't coredump on unclosed quotes.
4643 (quit_command): Use target_kill rther than kill_inferior.
4644 (_initialize_main): Rename class_user from "user" to
4645 "user-defined".
4646
4647 * printcmd.c (print_command_1): Initialize "fmt" if no format
4648 is specified by the user.
4649 (print_frame_args): Only add to args_printed if we are
4650 actually fetching args from the stack (avoiding undefined
4651 arg_size).
4652 (_initialize_printcmd): Remove bogus \{ from string.
4653
4654 * remote-eb.c (eb_open): Avoid coredump on no argument.
4655
4656 * remote-nindy.c: Bring out of Intel environment into new
4657 target environment. Remove all conditional compilation on
4658 I80960. Massive hacking throughout.
4659 (nindy_xfer_inferior_memory): New routine stolen from
4660 infptrace.c.
4661 (nindy_create_inferior): New routine pieced together, probably
4662 not quite working yet.
4663 (nindy_ops): New target_ops struct for nindy.
4664
4665 * remote-vx.c: Use write_memory rather than target_write_memory
4666 to get error checking.
4667 (vx_add_file_command, vx_open): Use symbol_file_add rather than
4668 add_file.
4669 (vx_create_inferior): Use target_terminal_ours...
4670
4671 * signame.c (_initialize_signame): Always initialize, since
4672 we need the table for things other than psignal.
4673
4674 * solib.c (solib_add): Use symbol_file_add, not add_file.
4675 (solib_address): Return boolean result rather than struct
4676 pointer which nobody else knows the type of.
4677
4678 * sparc-tdep.c, valops.c: Use write_memory rather than
4679 target_write_memory, to get error checking.
4680
4681 * stack.c (locals_info, catch_info, args_info,
4682 get_selected_block, frame_command, up_command): Use
4683 target_has_stack, rather than have_inferior_p or
4684 have_core_file_p.
4685
4686 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
4687
4688 * symfile.h: New file, defining the interface between the
4689 generic and object-file-specific symbol reading code.
4690
4691 * symtab.c: Move generic symbol-reading interface to symtab.c,
4692 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
4693 table to map BFD targets to symbol-reading modules in GDB.
4694 Change index to strchr.
4695 (lookup_struct_elt_type): Use error() rather than hand-made
4696 simulations thereof.
4697 (lookup_partial_symbol): Speedup slightly when length == 0.
4698 (symbol_file_add): New function.
4699 (symbol_file_command): Call it.
4700 (symfile_open, symfile_init): New function.
4701 (add_file_target_command, add_file_addr_command): moved from
4702 dbxread.c.
4703
4704 * target.c (target_command): use target_kill.
4705
4706 * target.h (target_files_info): Don't declare, never called
4707 from outside.
4708
4709 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
4710 files to determine stack end address.
4711
4712 * valarith.c (value_x_binop, value_x_unop): Change error message
4713 to be more useful. Pass proper argument to value_struct_elt.
4714
4715 * valops.c (value_assign): FIXME comment that long long
4716 bitfields will break here.
4717
4718 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
4719 Update `make saber_gdb' to work better.
4720
4721 * TODO: A woman's work is never done.
4722
4723 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
4724 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
4725 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
4726 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
4727 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
4728 valops.c, valprint.c, exec.c: Lint.
4729
4730
4731 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
4732
4733 Continuing Intel 960 port merge of GDB.
4734
4735 * Makefile.dist: Merge i960 "nindy-share" files. Rename
4736 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
4737 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
4738 Wack over "make depend" so it handles files in subdirectories
4739 vx-share, nindy-share, bfd, and in the current directory.
4740
4741 * blockframe.c (get_prev_frame_info): Remove fatal error
4742 if stack not defined.
4743
4744 * core.c (core_open, core_detach): New functions that handle
4745 the old "core-file" command as "target core" and "detach" instead.
4746 (core_file_command): Call them.
4747 (core_xfer_memory): Use common routine xfer_memory.
4748
4749 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
4750 dbxread now uses bfd for everything but symbol reading itself.
4751 BFD internals are used to drag out the relevant file offsets.
4752 (partial_symbol_file_open): Change args all around for BFD.
4753
4754 * symtab.c: Rename "value" to "val" everywhere, so we can
4755 #include "value.h".
4756 (symbol_file_command): New command, moved from dbxread.c
4757 and coffread.c. It uses BFD to read the file, then vectors
4758 based on its type, to dbx or coff symbol readers.
4759 * symtab.h: Extern a few vars for symbol_file_command.
4760
4761 * target.h: Breakpoint takes a char * save area, not a char **.
4762
4763 * valprint.c (val_print): When unpacking bitfields, offset
4764 the address in gdb of the value, if it is declared with a shorter
4765 type. Remove the last "runtime kludge test" of host byte order.
4766
4767 * utils.c: Remove old my_bfd_read routine.
4768
4769 * stack.c (frame_info): Use target_has_stack. Print program counter
4770 register's actual name rather than "pc", since it's called the
4771 "ip" (instruction pointer) on the i960 (sigh).
4772
4773 * target.c (target_command): Add command for selecting a target
4774 type and calling its open routine. This is used for initiating
4775 communication with a particular target, in a generic way.
4776
4777 * tm-i960.h: Update for modern gdb. Remove semicolons from
4778 various macros. Handle reading struct return convention, and
4779 error-out attempts to return structs with the "return" command.
4780 Be sure gdb doesn't think we know how to call functions in the
4781 inferior.
4782
4783 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
4784 to i960_xxx in lower case.
4785 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
4786 not being defined yet.
4787
4788 * remote.c (remote_open): Call start_remote to initialize
4789 wait_for_inferior during open.
4790 (remote_xfer_inferior_memory): Return length written rather
4791 than errno value.
4792
4793 * remote-vx.c (target_command -> vx_open): Use new generic
4794 target command.
4795 * remote-eb.c, inftarg.c, exec.c: ditto.
4796
4797 * infrun.c: Fix comments.
4798 (attach_program -> child_open): Use new generic target command.
4799 (wait_for_inferior): Clear saved register values before target_wait,
4800 so target_wait can set some of them if convenient.
4801
4802 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
4803 Return success indicator, not void.
4804 (child_xfer_memory): Avoid fetching initial word if we'll
4805 overwrite it anyway.
4806
4807 * infcmd.c (attach_command): Use new generic target open routine.
4808 (_initialize_infcmd): Update doc on attach and detach commands.
4809 (do_registers_info): Merge in a byte-order problem as a FIXME
4810 comment.
4811
4812 * findvar.c (find_saved_register): Avoid problem in current frame.
4813 (read_relative_register): Ditto.
4814 (write_register): Convert byte order on the way out.
4815
4816 * exec.c (file_command): Add.
4817 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
4818 (xfer_memory): Common function between core_xfer_memory and
4819 exec_xfer_memory.
4820 (exec_xfer_memory): Use it.
4821
4822 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
4823
4824 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
4825 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
4826 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
4827
4828 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
4829
4830 Merge Intel 960 port of gdb, continuing...
4831
4832 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
4833 symbol_file_command): Pass from_tty arg to hush 'em up.
4834
4835 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
4836 Add magic numbers for 960 COFF format.
4837

4859 "-se" switches as soon as they are encountered on the invocation line.
4860
4861 Fri Apr 20 13:47:15 PDT 1990
4862 Add -brk switch.
4863

4865 Add 'reset' command.
4866
4867 Wed Apr 18 09:48:07 PDT 1990
4868 After opening remote tty, wait for 1 second to go by without input
4869 from it before trying to talk to NINDY (fixes problems with the
4870 Heurikon HK80/V960E).
4871
4872 Mon Apr 4 16:33:05 PDT 1990
4873 Some output was not being suppressed in 'batch' mode.
4874
4875 Thu Mar 22 15:31:11 PST 1990
4876 Ask user if old symbol table should be deleted when new file is
4877 downloaded.
4878
4879 Allow user to run a program downloaded before gdb960 was brought up.
4880
4881 Correct "exec-file" help message for i80960 context.
4882
4883 Correct bug in calculating user space address: could occasionally
4884 corrupt user program.
4885
4886 Make sure to zero low-order bits in rip's because of bug in 960CA

4899
4900 Mon Oct 23 12:03:04 PDT 1989
4901 Use G960BASE and G960BIN environment variables to find 'sx' utility.
4902
4903 Mon Oct 16 14:15:09 PDT 1989
4904 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
4905
4906 Mon Oct 2 15:56:31 PDT 1989
4907
4908 Added 960CA disassembly support.
4909
4910 To simplify maintenance:
4911 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
4912 directly instead.
4913 - eliminated opcode.h: incorporates tables into i960-pinsn.c
4914 - moved 960-specific routines from i960-pinsn.c to i960-md.c
4915 - made disassembly interface identical to that in gdmp960.
4916
4917
4918
4919 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
4920
4921 * target.h: Allow targets to stack. Add target_has_memory,
4922 _registers, etc. Restructure memory access and "info files"
4923 to walk the target stack.
4924 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
4925 target.c: Change tables to match target.h.
4926 * inflow.c (child_mourn_inferior): pop child_ops.
4927 (generic_mourn_inferior): Use new has_stack flag.
4928 * infptrace.c (child_xfer_memory): New memory regime.
4929 * inftarg.c (child_files_info): New "info files" regime.
4930 * remote-eb.c: New memory regime, new info files.
4931 * remote-vx.c: New memory regime, new info files. Now use
4932 separate targets for VxWorks attachment to machine, and
4933 actually running a process under VxWorks, since one has
4934 stack & execution & regs and the other doesn't.
4935 * remote.c: New memory regime, new info files.
4936 * sparc-xdep.c (fetch_core-registers): New memory regime.
4937 * target.c: New routines and support for stacked targets,
4938 new memory regime, new info files regime.
4939
4940
4941 Generalize section handling for an arbitrary number of sections,
4942 including use of the new BFD (binary file) library.
4943 * gdbcore.h: Add struct section_table.
4944 * exec.c (build_section_table): Iterate all sections and
4945 record what gdb needs to know about them.
4946 (exec_command): Use it.
4947 (exec_xfer_memory): Use the table.
4948 (exec_files_info): Print the table.
4949 * core.c (core_file_command, core_xfer_memory, core_files_info):
4950 Likewise.
4951 * source.c (find_source_lines): Use bfd_get_mtime.
4952 * dbxread.c: Quick changes to make it compile with new BFD.
4953 * utils.c (error): Avoid using bfd_error in generic routines.
4954
4955 * core.c (core_fetch_registers): Get from the ".regs" section of
4956 the BFD core file.
4957 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
4958
4959 * inferior.h (attach_flag): Export.
4960 * infcmd.c (run_command): use new target_create_inferior.
4961 * infrun.c (child_create_inferior): Don't return result.
4962 * Makefile.dist (VERSION): 3.91.4.
4963
4964 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
4965
4966 * breakpoint.c (bpstat_num): Handle breakpoints which have
4967 since been deleted, such as temporary breakpoints.
4968 infcmd.c (program_info): ditto.
4969
4970 * core.c (core_file_command): Display the frame where the core
4971 dump occurred.
4972
4973 * main.c: lint.
4974
4975 * remote-vx.c (target_command): Merge in target command from
4976 targ-vx.c. A few other cleanups.
4977
4978 * TODO, Projects: Lots more stuff to do...
4979
4980 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
4981
4982 Massive changes to wall off the remote-debugging interface
4983 behind a function vector. The port to handle VxWorks targets
4984 is also part of this.
4985
4986 All files: Replace references to renamed functions,
4987 remove references to remote_debugging, remove references to
4988 have_include_file, have_core_file in favor of target_has_stack,
4989 target_has_memory, etc.
4990
4991 * Modularize the breakpoint interface.
4992 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
4993 a breakpoint instruction.
4994 breakpoint.c: struct breakpoint's shadow_contents now sized as
4995 BREAKPOINT_MAX.
4996 (insert_breakpoints): Vector to target to install breakpoints.
4997 (remove_breakpoints): Vector to target here too.
4998 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
4999 sparc-tdep.c (single_step): Use new breakpoint interface for
5000 the single-step breakpoints.
5001 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
5002 New file, contains routines to insert and remove breakpoints by
5003 reading out the old contents and later replacing them. This is
5004 how ptrace breakpoints work, and many remote systems as well.
5005
5006 * tm-vxworks68.h: New config file, overrides a few things for
5007 Wind River's preferences.
5008
5009 * target.h: New file, for transfer vector used to talk to the
5010 inferior (child, attached, core, exec, remote, etc). All accesses
5011 to the thing being debugged should come through these vectors.
5012 target.c: New file, routines to handle transfer vector.
5013 (various files): Add transfer vectors XXX_ops for the various
5014 targets and pseudo-targets (core files, etc) we support.
5015
5016 * breakpoint.c (bpstat_stop_status): Further explorations of
5017 watchpoints and why things don't work all the time.
5018 (bpstat_alloc): New fn to allocate a bpstat and chain it.
5019
5020 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
5021 the local gdbinit if it doesn't already have it.
5022
5023 * core.c (core_ops): add and install.
5024 Allow core debugging without exec file.
5025
5026 * dbxread.c (free_and_init_header_files): Merge two fns.
5027 (end_symtab): Free named symbol table when a new version comes in.
5028 (read_dbx_symtab): Relocate all kinds of symbols with base
5029 address. First step toward handling different text, data, bss
5030 reloc.
5031 (add_file_addr_command): Renamed add_file_command.
5032 (add_file_command): Vector to remote handler.
5033 Add "load" as an alias for "add-file" command.
5034
5035 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
5036 non-returning functions.
5037
5038 * exec.c: Add exec_ops, and push it as a target when an exec
5039 file is specified.
5040
5041 * infcmd.c (run_command): Pass executable file name and arg list
5042 separately when starting an inferior. Permit "run" when no exec
5043 file is specified, for VxWorks.
5044 (detach_command): Move to child_detach in inftarg.c.
5045
5046 * inftarg.c: New file. Unix-child-specific routines, and the
5047 child_ops structure.
5048
5049 * inferior.h (registers): Export "registers" as the way for
5050 target dependent register handlers to find gdb's local copy of
5051 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
5052 since it is now used by places that want wait_for_inferior to
5053 handle the grunge but want to see every trap from the inferior.
5054
5055 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
5056 Eliminate remote_debugging hooks in terminal handling.
5057
5058 * infrun.c: Replace start_inferior with child_create_inferior.
5059 Move all the hair of Unix shells and ptrace idiosyncracies into
5060 child_create_inferior, so remote handlers don't have to deal.
5061 Remove running_in_shell. Rename stop_after_attach to
5062 stop_soon_quietly, and use it in a few other places where we want
5063 to just call wait_for_inferior and get control back on the first
5064 trap. trap_expected now never takes a value > 1.
5065 (init_wait_for_inferior): Initialize static vars when a new
5066 process is created.
5067
5068 main.c (gdbinit): Add new hook for .gdbinit file name, let
5069 it be overridden by config files as GDBINIT_FILENAME.
5070 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
5071 Both of these are used for VxWorks gdb.
5072
5073 mcheck.c: rename include file "gmalloc.c" to avoid problems
5074 with system include file "malloc.c".
5075
5076 param-no-tm.h: New include file, same as param.h but does not
5077 include the default "tm.h" file. This is used in files where
5078 the target is known, e.g. remote-eb.c or sparc-xdep.c.
5079
5080 param.h: Now just a shell that includes tm.h and param-no-tm.h.
5081
5082 remote-vx.c: New file, VxWorks remote debugging support. Uses
5083 RPC routines that are shared with the target system, in directory
5084 ${srcdir}/vx-share.
5085
5086 remote.c: Vectorize remote interface.
5087
5088 source.c: Globalize source_path, and make an alias "l" for "list"
5089 since we now have the "load" command.
5090
5091 sparc-xdep.c: Use new param-no-tm.h.
5092
5093 symmisc.c (free_named_symtab): Add new function from Wind River.
5094 However, ifdef it out for now while we think about what it should
5095 really be doing.
5096
5097 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
5098 PREPARE_TO_STORE to
5099 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
5100 non-Unix-children handle this with their own code in the target
5101 transfer vector.
5102
5103 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
5104 source and target lists. Add vx-share to default list of include
5105 directories. Add new files to src and target lists: mem-break,
5106 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
5107 ${srcdir} versions of munch and createtags are used.
5108
5109 * valops.c (find_function_addr): Split out of call_function.
5110 (call_function_by_hand): Rename call_function; this function
5111 calls functions in the target by laboriously patching the target
5112 word-by-word with the right stack, args, regs, etc.
5113
5114
5115 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
5116
5117 Handle AMD 29000 a bit better.
5118
5119 * remote-eb.c (readchar): Mask received char log to make it readable.
5120 (remote_start): Pass arguments down to executing program.
5121 Make startaddr unsigned.
5122 infrun.c (start_inferior): Accept args, pass them to
5123 remote_start.
5124 infcmd.c (run_command): Pass args down to start_inferior.
5125
5126 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
5127 the target object file format.
5128 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
5129
5130 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
5131 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
5132
5133 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)

5144 (sparc_frame_find_saved_regs): Simplify and fix what we find.
5145 (sparc_push_dummy_frame): Simplify and fix what we push.
5146 (sparc_pop_frame): Slightly more hair here, deciding whether
5147 we are restoring a saved PC or returning to a return address in %i7.
5148 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
5149
5150 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
5151 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
5152 * obstack.h (chunkfun): ditto.
5153 * defs.h (xmalloc, xrealloc): ditto
5154
5155 * utils.c (quit): Grab the terminal from the child if necessary.
5156
5157 * inflow.c (term_status_command): Rename to term_info, change
5158 to "info terminal".
5159
5160 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
5161 (is_delayed_branch): Speed up.
5162 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
5163 Still missing some float ops, and needs testing.
5164
5165 * Support for input and output radixes other than base 10
5166 * defs.h (input_radix, output_radix): Declare.
5167 * expread.y (yyparse, parse_number): Handle changes of input
5168 radix, and ambiguous names-or-numbers in radixes >10.
5169 * printcmd.c (print_scalar_formatted): Print formatted hex
5170 numbers in varying column widths.
5171 * valprint.c (val_print): Use output_format to print scalar ints.
5172 (set_input_radix, set_output_radix, set_radix): Create.
5173 (set_output_radix): Set output_format from output_radix.
5174 (_initialize_valprint): add `set radix' but leave the others off.
5175
5176 * main.c (execute_command): Let stupid questions be turned off.
5177 (_initialize_main): Handle "set stupidity", etc.
5178
5179 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
5180 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.

5183
5184 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
5185 bfd stuff is still screwed up, but with some manual work, it
5186 compiles.
5187
5188 * breakpoint.c (bpstat_do_actions): Start over if a command
5189 proceeds the inferior, since the inferior will have stopped and
5190 will need to have its new stop-actions taken care of.
5191
5192 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
5193 compiler fits, simplify it.
5194
5195 * gdb.texinfo (directory command): Doc new dir command.
5196 source.c (directory_command): "dir" now puts things on the front
5197 of the path, moves dups up front, and handles multiple names
5198 on the command line, inserting each one in order. It also
5199 blows away cached line and full_filename info.
5200
5201 * stack.c (backtrace_command): Skip "more stack frames follow"
5202 unless interactive.
5203
5204 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
5205 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
5206 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
5207 The only odd one was Gould NP1, which had defined vprintf to
5208 "printf"!!!
5209
5210 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
5211 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
5212 variable, inspect_it.
5213 valprint.c (print_string, val_print): Use the global inspect_it
5214 to indicate whether to print in Epoch style or normal style.
5215
5216 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
5217
5218 * printcmd.c (call_command): add an alias for the "print" command
5219 which runs expressions and doesn't print the result if void.
5220 (print_command_1): implement it.
5221
5222 * command.c: Remove #if 0'd code. Initialize all the fields
5223 in add_cmd (). Rename do_nothing_command to
5224 not_just_help_class_command, and make it externally visible.
5225 command.h: add user_commands to struct.
5226 * main.c (define_command): Don't overload c->function with a char
5227 string as well as a function pointer.
5228
5229 * eval.c (evaluate_subexp): Reinstall tiemann changes to
5230 calling convention of value_struct_elt () that got dropped in
5231 merge.
5232
5233 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
5234 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
5235
5236 * tm-sparc.h (POP_FRAME): replace some constants with defines.
5237
5238 * sparc-xdep.c (store_inferior_registers): defer stores to regs
5239 until a good time (e.g. when we are about to run the child),
5240 saving ptrace calls.
5241 * infrun.c (proceed): handle DO_DEFERRED_STORES.
5242 * tm-sparc.h: define DO_DEFERRED_STORES.
5243
5244 * sparc-xdep.c (store_inferior_registers): when storing float
5245 registers, don't store stack regs too. When storing the SP,
5246 however, DO store the stack regs too. This fixes a bug in which
5247 the dummy frame is not recognized when a call_function finishes,
5248 because its frame pointer (in the stack regs) was never
5249 initialized.
5250 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
5251 even though we don't know how to read them from an inferior.
5252 valops.c (call_function): Comment about storing SP.
5253
5254 * infrun.c (save_inferior_status): Save away the original bpstat
5255 chain so it can be restored later. Install the copied version for
5256 use by whoever saved the status. It will be blow away by
5257 restore_inferior_status, and the original chain restored. This is
5258 important for people who have pointers into the original.
5259
5260 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
5261 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
5262 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
5263
5264
5265 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
5266
5267 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
5268 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
5269 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
5270
5271 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
5272
5273 * Merge Mike Tiemann's multiple inheritance changes from Sun.
5274 Store the baseclasses in a type struct starting from array element
5275 0 rather than from the unusual array element 1.
5276
5277 dbxread.c: the above.
5278 (virtual_context): Add
5279 Read new debug information about which virtual function table
5280 a virtual function is from, and store it in fn_field.fcontext.
5281
5282 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
5283 TYPE_FN_FIELD_STATIC_P.
5284
5285 symtab.c: the above.
5286 valops.c: the above. Handle pointer casts of object *'s.
5287 (search_struct_method): Add.
5288 (value_struct_elt): First arg is now a pointer to a value, and is
5289 modified on return.
5290
5291 valprint.c: the above.
5292 values.c (value_virtual_fn_field): Add type arg. Handle
5293 offsetting to the proper object when calling virtual fns.
5294 The above.
5295 (baseclass_addr): Add valuep arg.
5296
5297 * README: Document the current state of BFD config (missing).
5298 * TODO, ChangeLog, Makefile.dist: Roll version.
5299 * WHATS.NEW: Add summary of changes since 3.5.
5300
5301 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
5302
5303 * dbxread.c (read_struct_type): Clear bit vectors whenever
5304 we allocate one.
5305 symtab.c (B_CLRALL): define.
5306
5307 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
5308 using == rather than =. Huh... This fixes the dreaded problem
5309 wherein builtin_type_int becomes TYPE_CODE_FLT.
5310
5311 * core.c (info_files): Show the inferior pid.
5312
5313 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
5314 already knows how to look in the source directory.
5315
5316 * Remove psymtab hair from many places. Remove duplicated code
5317 for searching symbol tables. Hide psymtabs from most places.
5318 Make it fast to get from a psymtab to its symtab.
5319
5320 blockframe.c (blockvector_for_pc): Remove psymtab hair.
5321 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5322 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5323 dbxread.c: export psymtab_to_symtab, make it work if called N times.
5324 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
5325 new symtab completely. New psymtabs get symtab pointer
5326 initialized to zero. Remove MI warning printf.
5327 symtab.h: Comments. Add psymtab to symtab pointer.
5328 (PSYMTAB_TO_SYMTAB): New macro.
5329 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
5330 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
5331 compilation fields.
5332 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
5333 verbose is not set.
5334 (print_frame_info): Avoid special-casing symbols that have not yet
5335 been read in.
5336
5337 * source.c (open_source_file): Quick path if we have already
5338 located the source file by its full name.
5339
5340 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
5341 find_pc_psymtab. When a name is found in the misc function
5342 vector, search the symbol table for its mangled name, not the
5343 name that the user typed.
5344
5345 * bfd.h: Fix missing comment terminators, make #endifs match.
5346
5347 * valarith.c (value_less): Handle unsigned int comparisons.
5348 Add FIXME about pointer compares, which assume host and target
5349 pointers are the same.
5350
5351 * command.c (do_nothing_command): lint
5352 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
5353 fix comments on debug symbol format for visibility. Actually set
5354 visibility of symbols.
5355 main.c (echo_command): lint; use <readline/history.h>.
5356 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
5357 obstack.h (_obstack_blank): Rearrange pointer math to avoid
5358 pointing past end of allocated memory; saber complains.
5359 obstack.h: Declare the external functions that we use.
5360 valarith.h: use <string.h>
5361 solib.c (solib_add): lint.
5362
5363 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
5364
5365 * main.c (initialize_main): Default info_verbose to off, now that
5366 symbol reading is fast.
5367 (quit_command): Avoid clobbering exec_bfd while quitting.
5368
5369 * Initial BFD (binary file diddling library) merger:
5370 coffread.c: Change AOUTHDR to struct exe_hdr.
5371 dbxread.c: ditto.
5372 core.c: initialize initialized data at compile time.
5373 (core_file_command): Move from coredep.c, convert to bfd.
5374 (xfer_core_file): Convert to bfd.
5375 exec.c (exec_file_command): use bfd routines.
5376 gdbcore.h: BFD.
5377 mips-tdep.c: Remove exec_file_command and friends.
5378 source.c: bfd.
5379
5380 * coredep.c: (fetch_core_registers) Convert core_file_command to
5381 fetch_core_registers.
5382 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
5383
5384 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
5385 (my_bfd_read): More bogosity, which I don't think we call.
5386 (program_name): Remove this atrocity asap!
5387
5388 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
5389
5390 * From Per Bothner:
5391 values.c: allocate_repeat_value was not clearing the
5392 optimized_out field.
5393 (value_static_field): minor stylistic fix (wrong macro was used).
5394 valops.c (value_struct_elt_for_address): didn't work for C++
5395 static fields.
5396
5397 * signame.c (_initialize_signame): Initialize signal names once.
5398
5399 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
5400 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
5401 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
5402
5403 * remote-eb.c: Support user-settable baud rates on the serial port.
5404
5405 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
5406
5407 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
5408
5409 * tconfig/sun3os4: Remove warning about native assembler,
5410 since it also occurs in the xconfig file.
5411
5412 * findvar.c (registers): Allocate some slop after `registers'
5413 to prevent stray accesses from trashing the next variable.
5414
5415 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
5416 on the sun-3, by changing the #ifdef from `sun3' (which is not
5417 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
5418 vars, which happened to follow `registers' in the executable.
5419
5420 * readline/history.c (history_search): Heed gcc-2's advice
5421 and parenthesize && inside ||).
5422
5423 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
5424 tm-29k.c: Insert FSF copyright headers.
5425
5426 * remote-eb.c: Better comments.
5427
5428 * Makefile.dist: Update to 3.91.6.
5429 * TODO: note PREPARE_TO_STORE problem.
5430
5431 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
5432
5433 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
5434
5435 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
5436
5437 * infrun.c (wait_for_inferior, at end): Don't set up
5438 prev_* if the inferior no longer exists.
5439
5440 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
5441 CANNOT_EXECUTE_STACK.
5442 valops.c (call_function): Use it.
5443
5444 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
5445
5446 * inferior.h (PC_IN_CALL_DUMMY): New macro.
5447 infrun.c (wait_for_inferior, 2 places): Use it.
5448
5449 * values.c (value_being_returned): Only use
5450 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
5451
5452 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
5453 right thing for remote-eb.c.
5454
5455 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
5456 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
5457
5458 * blockframe.c: Put get_frame_saved_regs inside #if !defined
5459 (FRAME_FIND_SAVED_REGS).
5460
5461 * findvar.c ({fetch,store}_registers): Check for
5462 REMOTE_{FETCH_STORE}_REGISTER macro.
5463
5464 * findvar.c (get_saved_register): Add argument lval and
5465 change meaning of argument addr.
5466 findvar.c: Change calls to get_saved_register to reflect
5467 new calling convention.
5468 valops.c (value_assign): Use get_saved_register instead of
5469 find_saved_register.
5470
5471 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5472
5473 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
5474 an (uninitialized) pointer to one. Use "&" when passing it
5475 to fread.
5476
5477 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5478
5479 * coffread.c (getfilename): Use DGUX x_offset and x_name if
5480 defined.
5481
5482 * coffread.c (symbol_file_command): Put semicolon after
5483 "int from_tty".
5484 Put safe_to_init_tdesc_context in #if defined (TDESC).
5485 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
5486 coffread.c: #include <sys/stat.h>.
5487 (read_coff_symtab): Typo: in_source_files -> in_source_file.
5488 Add missing ')' in check for "lc%" and friends. Remove
5489 extraneous '}'.
5490 Declare read_one_sym() at top of file.
5491 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
5492 MC68WRMAGIC can have the same value without causing a duplicate
5493 case.
5494
5495 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
5496
5497 * Allow a Makefile to be built without building the
5498 tm and xm file links that screw up builds in subdirectories.
5499 This is done with `config.gdb none', then you can do things
5500 like `make gdb.tar.Z'.
5501 * tconfig/none: Config file for no target system
5502 * xconfig/none: Config file for no host system
5503 * config.gdb: If no TM or XM files are called out by the
5504 host or target file, don't make links for them.
5505
5506 * cplus-dem.c: Add documentation.
5507
5508 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
5509 simple error, so the user's gdb doesn't crash due to some object
5510 file problem (e.g. somebody is rebuilding the file out from under
5511 gdb).
5512
5513 * printcmd.c (print_address_symbolic): demangle the symbol.
5514
5515 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
5516 Motorola copyrights in it. Make "make gdb.tar.Z" work.
5517 (alldeps.mak): sort and uniq all results from this; duplicates
5518 hose gdb.tar.Z link building. Remove RCS files from
5519 tconfig and xconfig. Add config files for sun386. Add
5520 a few odd files to OTHERS and HFILES.
5521
5522 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
5523
5524 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
5525 Roll version number to 3.91.5. Make lint work in bindir.
5526
5527 * README: Document cross-debugging and new file structure.
5528
5529 * blockframe.c: Lint. Include "value.h" to declare read_register.
5530 (find_pc_partial_function): remove duplicate line.
5531
5532 * command.h: Lint. Declare error_no_arg and dont_repeat.
5533
5534 * tm-news.h: Remove inadvertently duplicated stuff.
5535
5536 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
5537 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
5538
5539 * config.gdb: Allow `config.gdb host target' form. Clean
5540 up previous change that printed bogus messages when you just said
5541 `config.gdb'.
5542
5543 * core.c: #include "command.h" for lint.
5544 * dbxread.c: lint
5545 * eval.c: lint
5546 * main.c: Remove some casts of enums. Lint.
5547 * source.c: lint
5548 * symtab.c: lint
5549 * symtab.h: lint
5550 * expread.y: lint
5551 * valarith.c: lint
5552
5553 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
5554
5555 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
5556 read it from memory. This will allow us to save ptrace calls
5557 eventually. Changed caller single_step too.
5558
5559 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
5560 that we aren't going to use, saving many ptrace calls, especially
5561 when watchpointing or single stepping. Use some #define's for
5562 constants.
5563 (store_inferior_registers): Ditto.
5564 (core_file_command): Use some #define's for constants.
5565
5566 * tm-sparc.h: Add #define's for some register numbers, so we
5567 can eliminate the use of random constants in sparc-xdep.c.
5568
5569 * stack.c (frame_command, print_frame_info, up_command,
5570 down_command) Remove frame_changed, since it
5571 causes a bug and doesn't seem to do anything useful. In some
5572 places it was used as a flag, in others as a stack level (?).
5573
5574 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
5575 default is to use the portable (vprintf) version rather than the
5576 kludge version.
5577 * xm-news.h (MISSING_VPRINTF): Add.
5578
5579 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
5580
5581 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
5582
5583 * Remove stuff that forces -Bstatic linking of gdb, and warnings
5584 about linking debugged programs -Bstatic in the sun?os4 config
5585 files in tconfig and xconfig subdirectories.
5586
5587 * main.c (main): Remove unreached exit(0) now that we exit
5588 via quit_command().
5589
5590 * Create TODO file for online bug list. There are too many
5591 "little" bugs to keep track of on paper.
5592
5593 * Change Projects file to refer to bug-gdb@cygnus.com
5594 rather than kingdon@ai.
5595
5596 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
5597
5598 * Makefile.dist (VERSION): 3.91.4 now.
5599
5600 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
5601 (condense_misc_bunches): Add sanity check that misc_count is
5602 the same as the number of symbols in the bunch.
5603
5604 * coffread.c: rename init_misc_bunches. Pass an argument
5605 to condense_misc_bunches (a zero).
5606
5607 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
5608 every time we are called; don't rely on our caller to do it.
5609 (add_file): Remove call to init_misc_bunches.
5610
5611 * mipsread.c: Only warn, don't error, if unknown symbol types.
5612 This keeps an old gdb from falling on its face if it sees newly
5613 extended symbol info. Rename init_misc_bunches.
5614
5615 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
5616
5617 * Merge in changes from Per Bothner for DECstations and other
5618 MIPS stuff. The rest is Bothner speaking:
5619
5620 The next message is a merger of Alessando Forin's mips port with
5621 mine. I've tried to use my good if biased judgment to get
5622 the best of both. It *does* need testing.
5623
5624 Some of the changes are general, *not* mips-specific.
5625
5626 param.h:
5627 Didn't believe in little-endian bit order.
5628 There are still inconsistencies about whether flags
5629 like BITS_BIG_ENDIAN are integer (#if ...) or
5630 boolean (#ifdef ...). I tried to paper over them.
5631
5632 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
5633 Moved some misc_function code that was common to
5634 {dbx,coff,mips}read.c to symtab.c.
5635 In the process, I think I cleaned things up a bit.
5636 At the same time, moved obsavestring and obconcat to symtab.c.
5637
5638 dbxread.c:
5639 Removed obsolete condense_addl_misc_bunches (use
5640 condense_misc_bunches(1) instead).
5641
5642 exec.c:
5643 Needed to include <sys/dir>, at least on DECstations.
5644
5645 valops.c, mips-tdep.c, tm-mips.h:
5646 Added PUSH_ARGUMENTS macro to support funny argument-pushing
5647 conventions (when STACK_ALIGN is insufficient).
5648 Needed on mips, where doubles need 8-byte alignment,
5649 but ints only need 4.
5650
5651 mips-opcode.h:
5652 Removed cruft that was not being used.
5653 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
5654
5655 mips-pinsn.c:
5656 Print $ before register-names (I think that makes things a little
5657 more consistent).
5658 Never print two instructions, even if one delays.
5659 Removed hex-disassemble set_cmd. (This is not mips-specific,
5660 so I think the argument is whether it is generally worthwhile or not.
5661 I'm inclined to think not, given how easy it is to
5662 convert between radixes in gdb.)
5663
5664 mipsread.c:
5665 This is basically Alessando's code.
5666 It doesn't use obstacks; I changed it to use obstacks
5667 in a few minor places where using malloc causes a
5668 memory leak. (Probably, more places could/should be changed.)
5669 I added record_misc_function where it was missing.
5670 In symbol_file_command and add_file_command, I tried
5671 to make the code consistent with more recent versions.
5672 Minor sylistic changes in parse_procedure.
5673 Make a .gdbinfo. psuedo-symbol point back to the real
5674 procedure symbol (using the isym field).
5675
5676 mips-tdep.c:
5677 This is basically from my port, but with a lot of details
5678 and a number of routines merged in from Alessando's version.
5679 I basically used my code "raw" backtrace (use heuristics
5680 from the actual code, rather than symbol table info) - though
5681 the idea is Alessandro's. I feel my code is a little cleaner
5682 here, particularly in being a little more flexible, such as being
5683 able to handle gcc-produced code (which it now can).
5684 It also doesn't do frame caching (which is not useful
5685 more recent gdb versions).
5686 I also used my code for push_/pop_dummy, more or less.
5687 I tried to incorporate AF's code for testing sigtramp
5688 while backtracing; I probably got it wrong.
5689 Added mips_print_register, which tries to scrunch as much
5690 information as possible on a screen...
5691 Removed the skip-prologue set_cmd. As with hex-disassemble (see
5692 under mips-pinsn.c), I don't see anything mips-specific here,
5693 and I don't see it being all that useful anyway.
5694
5695 tm-mips.h:
5696 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
5697 Use more register names (rather than hard-cases numbers).
5698
5699 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
5700
5701 * Hack up 3.90.11 changes:
5702
5703 * Makefile.dist (depend): parameterize $(GCC).
5704 Add solib.c and solib.o.
5705 (readline): Fix vpath for both absolute or relative SRCDIR.
5706
5707 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
5708 Also, let the part I didn't understand at least compile so
5709 I can test the rest. FIXME.
5710
5711 * dbxread.c: Fix thinko using strcmp.
5712 (init_psymbol_list): declare static.
5713 (partial_symbol_file_open): Comment cleanups better, avoid
5714 cleaning up the string table since the caller will do that.
5715 Move the stat for mod time into symbol_file_command, temporarily.
5716 (There should be a mod time for each symbol file, eventually,
5717 to control its rereading. FIXME.)
5718
5719 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
5720 SunOS, which gives error for shared libs otherwise. (From
5721 Schaefer, probably FIXME needs work for portability.)
5722
5723 * solib.c: Move #include "param.h" to work.
5724 Lowercase all the Uppercase Letters In the Messages.
5725 (find_solib): Clean up inferior_so_name for debug printouts.
5726 Allow no argument, to mean all shared libraries.
5727
5728 * symmisc.c: include param.h to get CLEAR_SOLIB.
5729
5730 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
5731
5732 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9

5734
5735 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)

5740
5741 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5742
5743 * Version 3.90.10.
5744
5745 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
5746
5747 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
5748
5749 * sparc-opcode.h Added single-operand version of rett.
5750
5751 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5752
5753 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
5754 Put parens around gcc_p in expansion.
5755
5756 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5757
5758 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
5759
5760 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5761
5762 * Changes for Sun shared libraries:
5763 blockframe.c (find_pc_partial_function): If a non-text symbol
5764 is found, set *address = pc - FUNCTION_START_OFFSET.
5765 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
5766 Disable breakpoints instead of giving an error.
5767 source.c (select_source_symtab): Initialize cs_pst.
5768 symmisc.c: Call CLEAR_SOLIB if defined.
5769 symtab.h: Make text{low,high} CORE_ADDR not int.
5770 (psymtab): New field addr.
5771 solib.c: New file.
5772 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
5773 (record_misc_function): Give correct type for N_DATA symbols.
5774 (condense_misc_bunches): do "misc_function_count = j" regardless
5775 of inclink.
5776 Take code which is shared between symbol_file_command and
5777 add_file_command and put it into partial_symbol_file_{open,read}.
5778 Split add_file_command into add_file_command and add_file.
5779 Make psymtab_to_symtab read in the string table if the file
5780 is not symfile.
5781 Two new parameters to read_dbx_symtab and start_psymtab.
5782 tm-sunos.h: New file.
5783
5784 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5785
5786 * infcmd.c: Change cont_command to continue_command and "cont"
5787 to "continue".
5788
5789 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5790
5791 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
5792
5793 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
5794
5795 * values.c (USE_STRUCT_CONVENTION): Check for structures of
5796 size 1,2,4,8 rather than size < 8.
5797
5798 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
5799 as necessary, not just once.
5800
5801 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
5802
5803 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5804
5805 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
5806
5807 * tm-news.h: Add CALL_DUMMY_*.
5808
5809 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
5810
5811 * config.gdb: In list_host, list_target, use ${i}, not $i.
5812
5813 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5814
5815 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
5816
5817 * sparc-opcode.h: Change all store floating-point state register
5818 instructions to have the right match & lose fields.
5819
5820 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5821
5822 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
5823 VPATH to readline.
5824 config.gdb: If srcdir != ., create readline directory and
5825 copy a makefile into it.
5826
5827 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
5828 consistency with POSIX.
5829
5830 * breakpoint.c (bpstat_stop_status): Disable watchpoint
5831 when we exit its exp_valid_block.
5832
5833 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
5834
5835 * Makefile.dist: Bump version to 3.91.3.
5836
5837 * Clean up handling of breakpoint commands (somewhat).
5838 Prompted by Tiemann bug report "cont 10" doesn't work any more.
5839
5840 inferior.h: Add breakpoint_proceeded to inferior status struct
5841 and globals; save it and restore it.
5842 (clear_breakpoint_commands): Cleanup, remove old #define.
5843
5844 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
5845 (save_inferior_status, restore_inferior_status): handle it also.
5846 (proceed): Remove earlier code that set breakpoint_proceeded.
5847 It is now set only in clear_proceed_status.
5848 (clear_proceed_status): Cleanup, use bpstat_clear rather
5849 than clear_breakpoint_commands. No callers need the stop_bpstat
5850 between clear_proceed_status and proceed.
5851
5852 infcmd.c: Add breakpoint_proceeded definition and comment.
5853 (cont_command, jump_command, signal_command): Move call to
5854 clear_proceed_status right next to call to proceed.
5855
5856 breakpoint.c (bpstat_do_actions): Avoid clobbering our
5857 caller's argument while running down the chain of breakpoints.
5858 Use new variable "breakpoint_proceeded" to determine when
5859 a command that it executes moves the inferior past the
5860 breakpoint.
5861 (bpstat_clear): Handle NULL argument.
5862 (bpstat_clear_actions): Avoid useless call to
5863 breakpoint_auto_delete.
5864 (delete_breakpoint): Clean up bpstat's that are pointing to
5865 the deleted breakpoint from the stop_bpstat chain.
5866 (breakpoint_auto_delete): Simplify.
5867
5868 * Clean up handling of EOF, error on stdin, etc. This was
5869 prompted by a network problem that caused gdb to go into an
5870 infinite loop filling up its malloc'd memory.
5871
5872 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
5873 not clear_breakpoints_commands, which is now gone.
5874 (main): If command_loop returns (e.g. from EOF on stdin), do
5875 a quit_command (looping back to command_loop if quit_command
5876 doesn't really quit).
5877 (command_loop): check result from command_line_input and
5878 exit if it returns NULL, rather than passing the NULL to
5879 execute_command.
5880 (gdb_readline): Free malloc'd result space before returning
5881 NULL for EOF.
5882
5883 * utils.c (query): Handle C-d to mean "yes", just as if the
5884 input was not a terminal. Also avoid infinite loop if EOF
5885 occurs in mid-input-line before newline. This allows
5886 query to be used at EOF on stdin with reasonable results.
5887
5888 * infrun.c (proceed): Set breakpoint_proceeded.
5889
5890 * values.c (value_as_long): Avoid infinite recursion for enums.
5891 (_initialize_values): Fix typo in help msg (kingdon).
5892
5893 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
5894 RL_LIB for linking. This allows -lreadline for linking
5895 and nothing for dependencies, once readline is a real library.
5896
5897 * config.gdb: Jim Kingdon: give useful error message if the
5898 host or target type is not recognized.
5899
5900 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
5901 it just defines it. Dumb, but deal with it.
5902
5903 * Jim Kingdon suggests:
5904 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
5905
5906 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
5907
5908 * Makefile.dist (VERSION): Bump version # to 3.91.2.
5909
5910 * Clean up Bothner's changes.
5911
5912 * blockframe.c (clear_pc_function_cache): New function.
5913 * blockframe.c: remake cache_pc_function_* static.
5914 * dbxread.c (symbol_file_command): remove references to
5915 cache_pc_function_* variables.
5916 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
5917 * printcmd.c: Avoid kludging a global variable (addressprint)
5918 to avoid printing the address of a string twice. Instead,
5919 pass the format letter 's' down low enough that it can be seen
5920 to avoid this problem.
5921 (print_formatted): Pass format arg to value_print.
5922 (restore_addressprint): Remove function.
5923 (do_examine): Avoid hacking addressprint, cleanups and such.
5924 (print_frame_args): Add a comment to a Bothner change.
5925 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
5926 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
5927 to wipe out the values cached in blockframe.c.
5928 * symtab.c (find_method): Add comment saying how big you must
5929 allocate to be "big enough". Per being terse again.
5930 * valprint.c (val_print): Handle format letter "s" to print
5931 strings without addresses. Add comment to vtbl printing code
5932 which casts with wild abandon. Rearrange reference-printing
5933 code so it prints:
5934 @0xaddr: value (print w/addressprint)
5935 value (print w/~addressprint)
5936 @0xaddr (parameter lists w/addressprint)
5937 or nothing (parameter lists w/o addressprint)
5938
5939 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
5940
5941 * Merge more changes from Per Bothner:
5942
5943 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
5944 annoying) that I tried to improve it. Here are my suggestions.
5945
5946 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
5947
5948 findvar.c:
5949 Do automatic de-reference when taking the address of a reference.
5950 printcmd.c:
5951 Don't deref_ref when printing parameter lists.
5952 valops.c:
5953 More attempts at treating refernences properly.
5954 valprint.c:
5955 In val_print, if deref_ref==0, don't print dangling " = ".
5956 value.h:
5957 Add COERCE_REF macro, which de-references an REF.
5958
5959 * Merge changes from Per Bothner:
5960
5961 * Fixed (Sony news)-specific configuration problems.
5962 * Fixed other problems with using vanilla pcc and libc (enum problems;
5963 assumption that vsprintf exists).
5964 * Some major speed-ups (finc_pc_partial_function now caches a match;
5965 parsing avoids duplicate symbol_lookup calls).
5966 * Changed handling of baseclasses (no longer use baseclasses field
5967 of struct type, use the first n_baseclasses fields instead).
5968 * Various minor changes/fixes, most C++-related.
5969
5970 blockframe.c:
5971 Cache the most previous match from find_pc_partial_function.
5972 (Save both low and high ends of matching function's pc range.)
5973 This speeds up the loop of infrun.c:wait_for_inferior quite
5974 a bit, and makes step/next commands much zippier.
5975 command.c:
5976 Added an enum->int cast (otherwise, some compilers barf).
5977 dbxread.c:
5978 No longer set baseclass offset to 0, since multiple
5979 inheritance now mostly works.
5980 Added a number of casts, to shut up compiler warnings
5981 (after stabs where made enums, not ints).
5982 When discarding a symbol table (in symbol_file_command),
5983 must clear the cache introduced in blockframe.c.
5984 Don't convert $vtbl_ptr_type to vtbl any more.
5985 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
5986 Mask off sign bit emitted by g++ for virtual table offset.
5987 Set voffset to -1 (not 1) for static member functions.
5988 expread.y:
5989 Changed parsing/lexing of names to avoid doing symbol lookup twice
5990 (once when lexing to determine symbol class, once for real).
5991 Now only call symbol_lookup once. Fields of 'this' win especially big.
5992 printcmd.c:
5993 Subpress printing addr twice in the case of 'x/s addr'.
5994 symtab.c:
5995 lookup_basetype_type is no longer used.
5996 Add find_methods as recursive helper function to decode_line_1.
5997 This allows multiple inheritance to work.
5998 Also, once one or more matches has been found, do not look in
5999 base-classes. (Baseclass methods would be overridden, anyway.)
6000 symtab.h:
6001 Removed baseclasses array in struct type.
6002 Instead of using baseclasses[i], use fields[i-1].
6003 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
6004 Changed sign convention of voffset (previous was inconsistent).
6005 tm-news.h:
6006 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
6007 utils.c:
6008 Used to assume existence of vsprintf. Re-written to not need it
6009 if HAVE_VPRINTF is undefined.
6010 valops.c:
6011 typecmp was too pessimistic. Made it less so.
6012 valprint.c:
6013 Don't print space after address.
6014 If vtable points to a misc symbol (with 0 offset), print it,
6015 since that indicates the actual class of the object.
6016 Changed ype_print_derivation_info to use new inheritance
6017 scheme (without baseclasses vector).
6018 values.c:
6019 In value_primitive_field, fixed some bugs left over from previous set of fixes.
6020 Also, changes needed because TYPE_BASECLASSES were removed.
6021 xm-news.h:
6022 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
6023
6024 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
6025
6026 * source.c:
6027 If there is no path set, and the symbols don't indicate what directory
6028 a file was compiled in, look in the current directory. But either
6029 a path or a known compilation directory will prevent this.
6030
6031 * dbxread.c:
6032 Three independent bug fixes:
6033 * Remove the #if 0 block that breaks some stuff.
6034 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
6035 adapt gdb to either SunOS 4.0.* or 4.1.
6036 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
6037
6038 * symtab.c:
6039 Instantiate the class T when looking for methods in it. (Tiemann@sun)
6040
6041 * valprint.c:
6042 (type_print) Demangle the name being printed.
6043 (type_print_base) Handle botched demangling without coredump (tiemann).
6044
6045 * values.c:
6046 (check_stub_method): Document routine.
6047 (tiemann) fix bug for no-arg functions
6048 Avoid clobbering beyond end of malloc'd storage.
6049 Terminate the argument list properly.
6050
6051 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
6052
6053 * Changes merged by John Gilmore:
6054
6055 breakpoint.c:
6056 In breakpoint_1, use new print_address_symbolic instead
6057 of find_pc_partial_function. (This forces use of assembler-level
6058 addresses, and avoids misleading non-mangled source-level names.)
6059 cplus-dem.c:
6060 Generalize ansi argument such that -1 means skip arglist totally.
6061 Removed global variable print_ansi_qualifiers (which made
6062 code non-reentrant), in favor of extra explicit arguments
6063 to internal routines.
6064 printcmd.c:
6065 Add new helper function print_address_symbolic.
6066 Use find_pc_misc_function instead of find_pc_partial_function
6067 (since we want assembler-level symbols here).
6068 stack.c:
6069 Print unknown function as just "f (...)", not "f (...) (...)".
6070 Use new fputs_demangled explicitly.
6071 symtab.c:
6072 Fixed a typing violation (problem: value.h cannot be imported
6073 without renaming many variable in this file).
6074 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
6075 decode_line_1: Moved forward some never-reached code.
6076 Made decode_line_2 skip function prologues correctly.
6077 utils.c:
6078 fputs_filtered should not demangle by default.
6079 Add new fputs_demangled to demangle on demand..
6080 valops.c:
6081 Change value_struct_elt to use value_primitive_field (using recursive
6082 utility function search_struct_field). This allows foo.bar to work
6083 for multiple inheritance (so far only for data fields).
6084 Change check_field in the same way (recursive helper function
6085 to support multiple inheritance).
6086 (Note: there are more of these problems that I haven't fixed.
6087 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
6088 value_of_this: 'this' symbol name is now just "this", note "$this".
6089 valprint.c:
6090 Don't print static members.
6091 Avoid printing "members of <type>" if there are none.
6092 Simplified type_print_derivation_info by merging duplicate code.

6094 value.h:
6095 Added declaration of new routine value_primitive_field.
6096 values.c:
6097 Added value_primitive_field which is generalized version of
6098 value_field that can handle multiple inheritance (non-zero offsets etc).
6099 Re-implemented value_field to call value_primitive_field.

6102
6103 * infcmd.c -- insert else to avoid 'delete env' coredump when you
6104 delete the whole environment. Karl Berry reported the bug.
6105 * source.c - fix openp to avoid //'s in filenames, which
6106 trigger an Emacs bug causing it to not be able to find files
6107 when running gdb in a window.
6108 * dbxread.c - zap the #if 0 that botches the add-file code.

6120 * added remote.sa-sparc.c, a modification of remote.c
6121 which conducts a dialog directly with the SparcStation prom.
6122 * breakpoint.c, infrun.c, sparcdep.c added
6123 remote_insert_breakpoint(), and remote_remove_breakpoint()
6124 to breakpoint.c instead of directly writing breakpoint instructions.
6125 * sparcdep.c on remote_debugging,there is no need
6126 to remove signle step breakpoint instructions.
6127 * main.c added "-epoch" flag and "int epoch_interface" to main.c
6128 global variable
6129 * printcmd.c - epoch interface sends lisp expressions to open up
6130 epoch windows on inspection.
6131 * valprint.c - added arrayprint, and addressprint and made adding
6132 format controls easier
6133 * wait.h added a couple of undef's because we were getting
6134 complaints about WSTOPSIG and WTERMSIG begin redefined.
