1 Thu Nov 7 04:51:19 1991 John Gilmore (gnu at cygnus.com)
3 * am29k-pinsn.c, am29k-opcode.h: Fix decoding of mtacc, dmac, fmac.
5 * tm-*.h: Remove READ_DBX_FORMAT, COFF_FORMAT, and
6 READ_MIPS_FORMAT, which have been unused since BFD. Still
7 remaining is COFF_NO_LONG_FILE_NAMES.
8 * tm-sun3.h, tm-altos.h: Remove detritus accidentally left from
9 function calling code moved to m68k-tdep.c.
11 Wed Nov 6 17:21:59 1991 John Gilmore (gnu at cygnus.com)
13 * coffread.c: Eliminate c_nsyms in favor of c_naux.
14 Complain if no auxents on .bf and .ef FCN symbols, and assume
16 (init_linenos, enter_linenos): Use a sentinel at the end of the
17 read-in linenos, to make for a fast, safe loop-end test.
19 Wed Nov 6 02:54:08 1991 Steve Chamberlain (sac at cygnus.com)
21 * coffread.c (read_coff_symtab): coffread used to rely on the
22 x_sym.x_misc.x_lnsz.x_lnno field giving the # of linnos in a
23 function. Two of the formats I'm using (29k and 88k) don't seem to
24 set it. Ths patch to fcn_last_line and (enter_linenos) is an
25 attempt to use the actual size of the linno table in the file to set
26 the number of linenos to process.
28 Tue Nov 5 22:47:46 1991 Steve Chamberlain (sac at cygnus.com)
30 * Makefile.in: put a - infront of the mv y.tab.c c-exp.tab.c and
31 mv y.tab.c m2-exp.tab.c, so that if bison is used, and the files
32 are created in place, so the mv fails, then the make continues.
34 Tue Nov 5 16:47:47 1991 Per Bothner (bothner at cygnus.com)
36 Add C++ as a separate language.
37 * defs.h (enum language): Add language_cplus.
38 * dwarfread.c (end_symtab): Support language_cplus.
39 * c-exp.y: Add new struct language_defn cplus_language_defn.
40 Don't set c to be the default language (see main.c).
41 * c-exp.y (yylex): Only look for field of this if
42 language is C++. (First difference from C!)
43 * language.c: Add case branches for C++ (currently, all
44 the same as C). Also, add c++ to "usage" note for "set lang".
45 * valprint.c (typedef_print). Add case branches for C++.
46 * main.c (main): New way to set initial language: Look at
47 file extension of psymtab containing main(). (Same as we
48 do for symtabs, but avoid loading the symtab yet.)
49 * symtab.c: New routine find_main_psymtab(), used by main()
50 to set initial language.
51 * symfile.c (allocate_symtab): Move code for mapping file
52 extensions-> languages to new deduce_language_from_filename().
54 Fix a C++ problem when looking for methods in super-classes.
55 There was confusion between base and derived types.
56 * valops.c (value_fn_field): Change function interface.
57 * values.c: Use new value_fn_field interface.
59 Mon Nov 4 10:49:33 1991 Per Bothner (bothner at cygnus.com)
61 * infrun.c: Fixed typo in comment.
62 * utils.c: All the v*fprintf emulation is now in libiberty,
63 so we can get rid of some junk.
64 * xm-sun3os4.h, xm-sun4os4.h, xconfig/decstation, xconfig/i386sco,
65 xconfig/sun3os4, xconfig/sun4os4: Don`t need HAVE_STRSTR any more.
66 * m68k-pinsn.c (print_insn_arg): Support BB/BW/BL
67 type operands, as used by branch instructions.
68 * gmalloc.c: Fix prototype of memcpy.
69 * elfread.c: Comment out register_addr, since it conflicts
70 with the one in coredep.c.
71 * buildsym.h: Remove extern declarations of two functions
72 that are really static in buildsym.c.
73 * tm-mips.h: Add symbolic names for more registers.
74 * mips-xdep.c (store_inferior_registers): Use new register names.
75 * xm-mips.h: Simplify REGISTER_U_ADDR, since it is now
76 only used for core files, not ptrace. Therefore,
77 the KERNEL_U_ADDR hack is no longer needed.
78 The mapping to ptrace number is now in in mips-xdep.c.
79 * mips-xdep.c: Define REGISTER_PTRACE_ADDR (using the
80 mapping from the old REGISTER_U_ADDR), and use it
81 in {fetch,store}_inferior_registers.
82 * mipsread.c: Rename #include ecoff.h to new name coff-mips.h.
83 * mips-tdep.c (mips_push_dummy_frame, mips_pop_frame):
84 Save/restore FP regs correctly (?).
85 * dbxread.c: Remove duplicate define_symbol and type_synonym_name
86 (these had been previously moved to buildsym.c).
87 Hence, define_symbol becomes extern instead of static.
88 * buildsym.c (read_struct_type): Comment out bogus handling
89 of C++ operator methods. Minor hacking of reading of class
90 contexts. Make define_symbol non-static, so dbxread.c can call it.
92 Fri Nov 1 11:05:47 1991 John Gilmore (gnu at cygnus.com)
94 * mipsread.c (read_mips_symtab, read_the_mips_symtab): Use real
95 filename with error messages.
96 * stack.c (frame_select_command): Rename to select_frame_command
97 to avoid "fr" and "fra" having nonunique completions.
98 * symfile.c (sort_symtab_syms): Ignore sort of zero symtab *.
99 (symfile_init): Print file format name when unable to handle it.
100 (free_named_symtabs): Use BLOCKVECTOR rather than obsolete BLOCKLIST.
101 * symmisc.c (free_symtab): Only free linetable if nonzero.
102 * symtab.h: Remove obsolete BLOCKLIST macros.
104 Thu Oct 31 18:12:43 1991 Stu Grossman (grossman at cygnus.com)
106 * infrun.c (wait_for_inferior): another stepi/nexti fix. Ensure
107 that stop_step is 1 at bottom of main loop. I don't know why this
108 needs to be done, but it helps me sleep better at night.
110 Sun Oct 27 18:18:39 1991 Stu Grossman (grossman at cygnus.com)
112 * main.c (initialize_history): Read history after reading all
115 Sun Oct 27 14:09:25 1991 John Gilmore (gnu at cygnus.com)
117 * buildsym.c: Break out initial malloc sizes.
118 (record_line): Record directly in a subfile. Alloc on demand.
119 (compare_line_numbers): Add from xcoffread.c.
120 (end_symtab): New params say whether to sort pendings and
121 linetable. Patch block stabs if defined. Shrink linetable before
122 allocating the symtab.
123 * buildsym.h: Delete line_vector* and prev_line_number. Add
124 global_stabs and file_stabs for xcoffread.
125 * dbxread.c (start_subfile): Move to buildsym. Change above calls.
126 * symtab.h: LINETABLE(symtab) can now be null. Zap LINELIST.
127 * symmisc.c, symtab.c: Cope with null LINETABLEs.
129 * blockframe.c: Pass fromleaf to INIT_EXTRA_FRAME_INFO.
130 * tm-29k.h, tm-88k.h, tm-i960.h, tm-irix3.h, tm-mips.h, tm-pyr.h,
131 tm-sparc.h: Accept fromleaf parameter.
132 * c-exp.y (yyerror): Pass error message if given.
133 * configure.in: Add rs6000 host and target.
134 * inflow.c (new_tty): O_NOCTTY kludge for RS/6000.
135 * symfile.h (entry_point): Add.
137 Sat Oct 26 00:16:32 1991 John Gilmore (gnu at cygus.com)
139 * buildsym.c: New file. Breaks out symbol-table-building routines
140 from dbxread.c, so they can be shared with xcoffread.c.
141 * buildsym.h: New file. Declarations for buildsym.c users.
142 * dbxread.c: Remove large chunks into buildsym.c.
143 * Makefile.in: Add buildsym.c and buildsym.h.
145 * symfile.c (syms_from_bfd): New routine.
146 (add_symbol_file): Call it to do the real work.
147 (syms_from_bfd): Initialize entry_point before calling symfile_init.
148 * symtab.h, symfile.c, coffread.c, mipsread.c, dwarfread.c:
149 Avoid declaring or setting entry_point (symfile.h & symfile.c cope).
151 Fri Oct 25 18:59:32 1991 Per Bothner (bothner at cygnus.com)
153 Various fixes to improve g++ debugging.
154 * symtab.h: Add is_const and is_volatile flags for each method.
155 These are bit fields - take their space from voffset,
156 which shrinks to 30 bits. Since voffset is now a bitfield,
157 make it unsigned for portability. This changes its interpretation
158 slightly: Static methods now have voffset 1 instead of -1,
159 and virtual offsets start at 2, not 1.
160 * symtab.c: Renamed gdb_mangle_typename to gdb_mangle_name,
161 since it now returns an entire magled method name, not just
162 the type part. This avoids some duplication.
163 It also allows us to correctly mangle const and volatile
164 methods (using the new is_const and is_volatile bit fields
166 * valprint.c (type_print_base), values.c (check_stub_method):
167 Simplify by using new gdb_mangle_name.
168 * values.c (value_headof): Fix to correctly handle single
169 inheritance (actually two fixes, either of which suffices).
170 * dbxread.c (read_struct_type): Handle const and volatile
172 * dbxread.c (read_struct_type): Yet one more place where
173 we must handle '\\' continuations.
174 * valprint.c (vtbl_ptr_name): Add final '\0'.
176 Fri Oct 25 16:06:38 1991 Stu Grossman (grossman at cygnus.com)
178 * tm-sparc.h, tm-68k.h (EXTRACT_RETURN_VALUE): fix output of
179 short return values for sparc and 68k. Patch from Paul Eggert.
181 * coffread.c, coredep.c, i386-xdep.c: install patches for
182 SysV/386 3.2 from Mauro DePalma.
184 Fri Oct 25 02:02:13 1991 John Gilmore (gnu at cygnus.com)
186 * core.c (core_file_info), exec.c (exec_file_info): Print file
187 type. Use printf_filtered.
189 * valops.c (value_fetch_lazy): Avoid 0-length fetches.
191 Thu Oct 24 23:06:40 1991 Fred Fish (fnf at cygnus.com)
193 * dwarfread.c: Add casts to remove compiler warnings.
195 * tm-3b1.h, tm-68k.h, tm-altos.h, tm-amix.h, tm-hp300bsd.h,
196 tm-hp300hpux.h, tm-isi.h, tm-news.h, tm-pn.h, tm-sun2.h,
197 tm-sun3.h: Remove locally duplicated code for calling functions
198 in the inferior. The only differences were in the specific trap
199 vectors used and whether or not an fpu was present. These are
200 now handled by appropriate definitions of BPT_VECTOR and
201 HAVE_68881 respectively. Other minor obvious cleanups.
203 * valops.c: Correct a minor misspelling.
205 * utils.c: Remove local BSD/USG hacks that are now in libiberty.
207 * dwarfread.c: Remove prototype for dwarfwarn. Does not work
210 Thu Oct 24 09:33:44 1991 John Gilmore (gnu at cygnus.com)
212 * stack.c (frame_command): Always print. Use new
213 frame_select_command to select a frame without printing.
215 * dwarfread.c: Use <varargs.h>, since <stdarg.h> is not portable.
217 Thu Oct 24 01:32:51 1991 Fred Fish (fnf at cygnus.com)
219 * dwarfread.c: New file for DWARF debugging format support.
221 * elfread.c: New file for ELF object file format support.
223 * procfs.c: New file for SVR4 /proc (process file system) support.
225 * tm-amix.h, xm-amix.h, tconfig/amix, xconfig/amix: New files for
228 * xm-svr4.h, tm-svr4.h: New files for SVR4 support.
230 * xm-m68k.h: New file for host machines with m68k cpu.
232 * Makefile.in: Add elfread.c and dwarfread.c to SFILES_MAINDIR.
233 Add elfread.o and dwarfread.o to OBS.
235 * symfile.h: Add "elf" to list of supported formats in comment.
237 * c-exp.y, defs.h, symtab.h, valprint.c: Add three new builtin
238 types to gdb, builtin_type_long_double, builtin_type_complex, and
239 builtin_type_double_complex. Add and use new TARGET_SHORT_BIT,
240 TARGET_INT_BIT, TARGET_LONG_BIT, TARGET_FLOAT_BIT,
241 TARGET_DOUBLE_BIT, TARGET_LONG_DOUBLE_BIT, TARGET_COMPLEX_BIT, and
242 TARGET_DOUBLE_COMPLEX_BIT, as the sizes in bits of the indicated
243 types on the target machine (ala the existing TARGET_LONG_LONG_BIT).
245 * infrun.c: When using SVR4 /proc interface instead of ptrace(),
246 call proc_set_exec_trap() to setup child to stop at first instruction.
248 * inftarg.c: When using SVR4 /proc interface, call proc_wait()
251 * m68k-tdep.c: Add new routines supply_gregset(), fill_gregset(),
252 supply_fpregset(), and fill_fpregset(), which are machine
253 dependent support routines for SVR4 /proc interface.
255 * utils.c: Add warning_setup() and warning(). Warning() behaves
256 the same as error() except that it returns normally rather than
257 jumping back to command level. Modules that don't want to call
258 warning() for some reason, but want to produce their own warnings,
259 can call warning_setup() to ensure compatibility with the way
260 warning() and error() deal with the terminal.
262 * symtab.c: Make internal errors produce more useful messages.
264 * tm-68k.h: Move code that is duplicated in almost every single
265 m68k based machine's configuration files to this common file.
266 Duplications in the configuration files still need to be removed
269 * infrun.c (child_create_inferior): System V versions must call
270 setpgrp() with no arguments, to comply with prototyping typically
273 * munch: Add support for SVR4 style nm output.
275 * dbxread.c, mipsread.c symmisc.c, symtab.c: Remove the object
276 file specific fields from the partial symbol table structure and
277 replace them with a pointer to private data for each different
278 flavor of object file reader to initialize appropriately.
280 Wed Oct 23 09:38:20 1991 John Gilmore (gnu at cygnus.com)
282 * xconfig/sun[34]os4: Add note about strstr botch on sunos4.0.3c
285 * mipsread.c (fixup_undef_type): New function. If a struct /
286 union / enum is defined in a header file but nowhere else used,
287 (by typedefing, pointer referencing or declaration) the mipsread code
288 builds the complete tree for the structure but leaves its code as
289 TYPE_CODE_UNDEF as it doesn't know what kind of aggregate it is.
290 Guess its type based on the details of the members.
292 Tue Oct 22 18:04:32 1991 Stu Grossman (grossman at cygnus.com)
294 * infrun.c (wait_for_inferior): Check return value from
297 Mon Oct 21 17:47:03 1991 Stu Grossman (grossman at cygnus.com)
299 * infrun.c (wait_for_inferior): fix stepi/nexti that was broken
300 by my last edit to this routine.
302 Mon Oct 21 14:27:43 1991 John Gilmore (gnu at cygnus.com)
304 * tm-sun3.h (FIX_CALL_DUMMY): problem with cross debugging.
305 FIX_CALL_DUMMY does unaligned accesses and/or forgets to byte swap
306 the values before putting them into the dummy code. (From Peter
309 Mon Oct 21 10:04:39 1991 Steve Chamberlain (steve at rtl.cygnus.com)
311 * configure.in: added ebmon target.
313 Wed Oct 16 22:49:58 1991 John Gilmore (gnu at cygnus.com)
317 * Makefile.in: Roll VERSION to 4.2.
318 * README, TODO, WHATS.NEW: Update.
320 * core.c (core_open): Improve error message for bad file.
321 Pass .reg virtual memory address to fetch_core_registers to help
322 it find the registers in the core-file header.
323 * coredep.c (fetch_core_registers): Take new argument, use it,
324 and pass it to register_addr to locate the block of registers.
325 * xm-mips.h: Update KERNEL_U_ADDR for new scheme. Cleanup a bit.
327 * dbxread.c (read_dbx_symtab, process_one_symbol): Handle
328 Sequent N_FN_SEQ like everybody else's N_FN.
330 * main.c: Circumvent SCO cc bug with #if !!defined(USG).
331 * tm-i386v.h: #endif guck.
332 * xconfig/i386*: Remove -Dgetpagesize()=4096 kludge.
333 * xconfig/i386sco: Add HAVE_STRSTR to avoid ANSI bdeath.
334 * xconfig/tahoe: Add REGEX, which seems to be missing.
336 * coredep.c: Add <sys/types.h> for SCOnix.
337 * dbxread.c (read_dbx_symntab): Avoid coredump on malformed file.
338 * printcmd.c (print_formatted): Flush output before disassembly.
340 Tue Oct 15 20:12:32 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
342 * doc/refcard.tex (sec "Working Files"): consistent metavars and
343 other improvements, due to comments by François Pinard
344 (pinard@iro.umontreal.ca)
346 * doc/gdb.texinfo (appendix "Installing GDB"): changes in
347 configure, and improvenets related to Pinard's refcard comments
349 Tue Oct 15 08:45:12 1991 John Gilmore (gnu at cygnus.com)
351 Changes from Fred Fish:
352 * tm-68k.h (FPI_REGNUM): Add.
353 * infrun.c (child_create_inferior): flush stdout and stderr

356 * inflow.c: Handle TIOCGLTC_BROKEN for Amiga.
359 * values.c (show_convenience): Use printf_filtered.
360 * main.c (define_command): Check result of lookup_command for
362 (echo_command): Use printf_filtered, and force output out.
364 * dbxread.c (read_enum_type): Avoid Modula-2 kludge that breaks C
366 * i387-tdep.c (double_to_i387): Fix typo for double_to_ieee_extended.
367 * utils.c (_initialize_utils): If !ISATTY, don't paginate.
368 * configure.in, tconfig/decstation, xconfig/decstation: Rename
369 dec3100 to decstation.
371 Mon Oct 14 13:37:50 1991 Roland H. Pesch (pesch at cygnus.com)
373 * doc/gdb.texinfo: Catch up to changes recorded here in ChangeLog
374 (nodes Continuing and Stepping; Memory; Targets) clarifications
377 Fri Oct 11 23:27:06 1991 John Gilmore (gnu at cygnus.com)
379 * tm-{irix3,mips,nindy960,pn,symmetry,vx960}.h: Move
380 REGISTER_U_ADDR to corresponding xm- file. Sugg. by Peter Schauer.
382 * symmisc.c (print_partial_symtabs): Add printpsyms debug cmd.

385 generic routines for calling inferior functions.
387 * blockframe.c (inside_main_scope, inside_entry_scope): New.
389 * copying.awk: Filter formfeeds out of copying & warrantee.
390 Make them available as `show copying' and `show warrantee' also.
391 * main.c (print_gnu_advertisement): Advt `show' commands.
393 Thu Oct 10 17:25:47 1991 John Gilmore (gnu at cygnus.com)

396 core-file reading code.
397 * core.c (get_core_registers): Avoid coredump if no .reg section.
399 Wed Oct 9 17:03:34 1991 John Gilmore (gnu at cygnus.com)
401 * mipsread.c, coffread.c: initialise TYPE_VPTR_FIELDNO to -1.
402 This avoids coredumps under `set print object on' in value_headof
403 (called erroneously by value_from_vtable_info) for `p &struct'
404 or `p *struct'. From Peter Schauer.
406 Mon Oct 7 00:06:52 1991 John Gilmore (gnu at cygnus.com)
408 * Makefile.in: Roll version to 4.1.2.
409 * dbxread.c: Use aout64.h, not a.out.gnu.h. Get external symbol entry
410 size from BFD (but, FIXME, we don't yet read external nlists's and
411 convert them to internal nlists's before handling them -- we still
412 assume they have the same size and alignment.) Use SET_NAMESTRING
414 * exec.c (exec_file_command): Move dead coff-encapsulation code
416 * m88k-tdep.c, m88k-xdep.c: Remove encap test and #inc <a.out.h>.
418 Fri Oct 4 22:30:06 1991 John Gilmore (gnu at cygnus.com)
420 * configure.in, tm-i386v.h, xm-i386v.h: Intel 386 Mach host port.
421 * xm-i386mach.h, mach386-xdep.c, xconfig/i386mach: New files.
423 Fri Oct 4 17:04:31 1991 Per Bothner (bothner at cygnus.com)
425 More patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
426 * mips-xdep.c (store_inferior_registers): Don't try to
427 write the (pseudo) FP.
428 * mipsread.c (parse_partial_symbols): Improved algorithm for
429 setting pst->texthigh.
431 Fri Oct 4 16:47:32 1991 Roland H. Pesch (pesch at cygnus.com)
433 * doc/Makefile: make TEXINPUTS include . everywhere
435 Fri Oct 4 00:35:56 1991 John Gilmore (gnu at cygnus.com)
437 * coffread.c, dbxread.c, symfile.c, symmisc.c, symtab.h: Remove
438 vestiges of typevectors, which were for symsegs and are no longer
439 used. (From a question by Eliot Dresselhaus
440 <dresselh@RFT30.nas.nasa.gov>).
442 Thu Oct 3 09:33:26 1991 John Gilmore (gnu at cygnus.com)
444 * dbxread.c, coffread.c: static-ize functions that were
445 gratuitiously external. (From Fred Fish.)
447 * c-exp.y: sym->class to SYMBOL_CLASS (sym).
449 * dbxread.c (dbx_lookup_type): Keep doubling size of typevector
450 until it is large enough.
452 * dbxread.c (read_type): Handle error case slightly better.
453 Make complaint message not C++-specific.
455 Wed Oct 2 17:21:07 1991 Stu Grossman (grossman at cygnus.com)
457 * infrun.c (wait_for_inferior): Fix step/next so that you only
458 stop at the beginning of a new line. This fixes various problems
459 with for loops, nested if-else's and switch statements.
461 Tue Oct 1 06:33:55 1991 John Gilmore (gnu at cygnus.com)
463 * symtab.c (lookup_symtab_1, lookup_symbol): "fatal" errors
464 between symtabs and psymtabs become ordinary error()s.
466 * dbxread.c (read_dbx_symtab): Relocate end_of_text_addr
467 properly, making "end pc" correct in shared lib psymtabs.
468 (From Guy Harris <guy@auspex.com>.)
470 Mon Sep 30 13:15:31 1991 John Gilmore (gnu at cygnus.com)
472 * dbxread.c: Enable, but soften, const_vol_complaint.
473 (read_dbx_symtab): N_STSYM and N_LCSYM define static vars.
474 Ditto Gould N_NBSTS and N_NBLCS. Also, all types in the psymtab
475 should be file-scope, not global.
476 (read_struct_type): Remove ancient multiple-inheritance warning.
477 (read_range_type): Check base type, complain & patch if undefined.
478 * stack.c (frame_info): Demangle the function name in `info stack'.
481 Sat Sep 28 10:02:33 1991 John Gilmore (gnu at cygnus.com)
483 * eval.c (evaluate_subexp_for_address): Don't use
484 TYPE_POINTER_TYPE directly (it might be zero if this type has
485 never had a pointer created before); use lookup_pointer_type.
486 * symtab.c (lookup_method_type): Arguments were swapped in all
487 callers, so fix it here. I'm amazed this worked at all!
489 Fri Sep 27 18:09:31 1991 John Gilmore (gnu at cygnus.com)
491 * c-exp.y, m2-exp.y: Define more yysymbols that happen to be
492 "bss" rather than "data" symbols, but which still conflict.
495 * coffread.c (coff_symfile_read): Use xmalloc, not malloc.
496 * core.c (core_files_info): Shorten output.
497 * exec.c (exec_files_info): Ditto.
498 (build_section_table): Ignore zero-length sections.
499 * language.c, printcmd.c: Lint.
500 * language.h (get_frame_language): Declare.
501 * saber.suppress: update.
502 * stack.c (find_relative_frame): Remove complex code that was
503 #if 0'd, stick with simple code. Lint.
504 * saber.suppress: Update a bit.
505 * symfile.c (add_symbol_file_command): Add "?" to question.
506 * utils.c (parse_escape): Avoid \a due to bdead compilers.
507 * value.h: Declare typedef_print.
509 * valprint.c (val_print, type_print_base): TYPE_CODE_RANGE less
512 * nindy-tdep.c (nindy_frame_chain_valid): Use lookup_misc_func.
513 (Reported by Mark Peek <mark@imagen.com>.)
515 * solib.c (solib_map_sections): Relocate all sections, even
516 though only the text section's size is tracked. Mark ld_text
517 for eventual elimination as we generalize to N sections.
519 * infrun.c (wait_for_inferior): Don't check if the PC is in a
520 call_dummy if we were stopped by a random signal that is being
521 passed to the program. This produced wierd results when calling
522 functions in the inferior and signals (e.g. SIGALRM) were in use.
524 Tue Sep 24 18:05:30 1991 John Gilmore (gnu at cygnus.com)
526 * infrun.c (IN_SIGTRAMP): Not parenthesized properly.
527 Bugfix from Paul Eggert <eggert@twinsun.com>.
528 * tm-ultra3.h (IN_SIGTRAMP): Ditto.
529 * valprint.c (print_floating): Print 9 digits for IEEE floats.

538 Fri Sep 20 16:10:52 1991 John Gilmore (gnu at cygnus.com)
542 * Makefile.in (VERSION): Set to 4.1.
543 * language.c (set_language_command): Print useful help message,
544 and restore the language string after giving help.
545 * valprint.c (typedef_print): Print typedef in C or M2.
546 * symtab.c (list_symbols): Use it.
547 * main.c (main): Avoid any output before (gdb) prompt when -q.
548 * language.c (set_language_command): Handle errors by restoring
549 the language string to its current state (fix from A. Beers).
550 * doc/gdbint.texinfo: Roll in information from README. Rearrange
551 "how to install" and "how to print the doc" stuff so it drops
553 * configure.in: Rename rtpc CPU to romp to match config.sub.
554 * README, WHATS.NEW, TODO: Update for gdb-4.1.
556 Fri Sep 20 17:39:14 1991 Roland H. Pesch (pesch at cygnus.com)
558 * doc/gdb.texinfo: Updates from ChangeLog. set/show write,
559 autoloading shared libs, copyright etc on GDB startup, clean up $_
560 and $__ index refs, set/show listsize and related updates to list
561 cmd. New host/target configs.
563 Fri Sep 20 15:46:00 1991 Roland H. Pesch (pesch at cygnus.com)
565 * doc/Makefile: generate aux version-no file doc/gdbVN.m4
566 from main Makefile.in version definition
567 doc/gdb.texinfo: use version recorded in doc/gdbVN.m4 for current
569 Makefile.in (setup-to-dist): generate doc/gdbVN.m4
571 * doc/gdb.texinfo: merge new language-switching and lang-specific
574 Fri Sep 20 15:00:57 1991 Per Bothner (bothner at cygnus.com)
576 * mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
577 compilers (which may lack stddef.h).
579 Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com)
581 * dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and
582 N_WARNING are the same except for the N_EXT bit, so just use their
583 values alone, rather than OR-ing them with N_EXT.
585 Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com)
587 * mipsread.c (parse_lines): Deal with negative extended line
590 * c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid
591 global symbol conflicts.
593 Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
595 * .gdbinit: Move 'set complaints' to top, so it runs even in
596 case we aren't debugging GDB.
597 * language.c (_initialize_language): Fix type check and range
598 check documentation strings.
599 * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
600 language.c can use it. (Though language.c should really not be
601 handling warnings/errors the way it does, FIXME.)
602 * symtab.c (lookup_primitive_type): const lint.
604 Bugfix from Peter Schauer:
605 * source.c (lines_to_list): Make signed, to avoid comparison
606 going unsigned and complaining that -3 is too high for 21 lines.
607 * stack.c (lines_to_list): Ditto.
609 Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
611 * Makefile.in (HFILES): Add minimon.h.
612 (VERSION): Roll version number to 4.0.95.
613 (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
614 New rules for building distributions. Normal distribution
615 is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
616 one level up from here; it calls make-proto-gdb.dir to build a
617 directory `proto-gdb' which is an image of the release. The old
618 `gdb.tar.Z' rule still works too.
619 * config.sub, configure: Roll in latest from ..
621 Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
623 * doc/gdbint.texinfo: Reorder contents; reorganize new-host,
624 new-target, and new-config chapters; fix minor typos; come closer
625 to usual GNU markup conventions for @file @samp @code @var.
627 Thu Sep 19 17:04:12 1991 Per Bothner (bothner at cygnus.com)
629 Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
630 * mipsread.c (parse_partial_symbols): Enter the name of all
631 structs/unions... into the psymtab so we can access them if the
632 symtab is not read in.
633 * mips-tdep.c: Remove some unneeded #includes.
634 * xconfig/dec3100: Add HAVE_STRSTR.
636 Thu Sep 19 15:14:23 1991 John Gilmore (gnu at cygnus.com)
638 * Makefile.in: Circumvent Sun Make bug on *-exp.tab.o.
639 * c-exp.y, m2-exp.y: Lint.
640 * m2-exp.y: Avoid using yytname[] which is a Bison-ism.
641 * valprint.c (val_print_fields): Check for stub type.
642 * mipsread.c (_initialize_mipsread): Avoid using
643 builtin_type_void at initialize time.
644 (mipscoff_symfile_read): use it now.
646 Wed Sep 18 15:55:51 1991 John Gilmore (gnu at cygnus.com)
648 Merge multiple-language support, and partial Modula-2 support,
649 from Andrew Beers <beers@cs.buffalo.edu>.
651 * i387-tdep.c: New file, consolidates most 80387 support,

669 #if 0 out its uses, though, since they set a dead value.
670 * coffread.c (end_symtab): Use allocate_symtab.
671 (process_coff_symbol): #if 0'd for functions and params as above.
672 (read_enum_type): Recognize Modula-2 BOOLEAN.
673 * symtab.c (add_param_to_type): #if 0'd function to add a

745 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
747 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
748 entries are enclosed herein. Not all of these changes
749 have been merged into the master GDB sources -- check the
750 ChangeLog above here for the merge log.
752 Mon Jun 3 17:05:45 EDT 1991
754 m2-exp.y Created. Tested outside of GDB for a few days. Proper
755 operators were added, C specific operators and tokens
756 removed. yylex() revamped to some extent. Still things
757 missing from the grammar, such as sets.
758 Tested for two weeks in GDB v3.5.
760 Tue Jun 11 17:23:48 EDT 1991
762 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
763 so they are built-in. Sort of a hack.
765 Fri Jun 14 12:53:51 EDT 1991
767 m2-exp.y Added range checking for numeric constants. Any numeric
768 constant is assumed to be of builtin type INTEGER unless:
769 (1) it is octal or hexadecimal, in which case it is a
770 CARDINAL; (2) it is too big to fit into an INTEGER, in
771 which case it is a CARDINAL.
772 eval.c Added simple range checking for +, -, and * on integers.
773 Doesn't work very well for *, since 6 * 1,000,000,000 =
774 1,705,032,704, which fails the simple test of result >=
775 first_operand, no matter in what order the operands are.
777 Tue Jun 18 14:11:30 EDT 1991
779 Broke the parser into parts, one containing the C grammar and the other
780 containing code to be shared by all of the grammars.
782 The following files no longer exist:
787 The following files were added:
789 c-exp.y (The C grammar)
790 m2-exp.y (The Modula-2 grammar)
791 parser-code.c (Code that is shared by the above grammar)
795 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
796 now necessary to use the Bison compiler compiler, since it
797 will generate function/variable prefixes other than yy.
799 Tue Jun 18 16:47:49 EDT 1991
801 symtab.[ch] Added the external variable working_lang, than holds the
802 value of the current working language.
803 Added the ennumerated type language_mode, with the values
804 language_auto and language_manual, the former meaning that
805 GDB sets working_lang as needed, and the latter meaning
806 that the value of working_lang is totally under user
808 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
809 REAL, BOOLEAN and CHAR. Also added the type codes
810 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
811 utils.c Added set_language_command and show_language_command to
812 implement the GDB support commands "set language" and
814 expression.h A number of identifiers were added to the type exp_opcode
815 to facilitate Modula-2 builtin functions, integer
816 division, and array indexing.
818 Wed Jun 19 13:25:58 EDT 1991
820 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
821 if the language specified by working_lang requires the use
822 of strict typing of expressions. Eventually, even this
823 will be able to be changed by the user.
824 Added the macro RANGE_CHECK, which evaluates to non-zero
825 if the language specified by working_lang requires the
826 checking of a value against the domain of its type.
827 Eventually, even this will be able to be changed by the
829 language.[ch] Predicates involving types (simple_type, ordered_type,
830 same_type, integral_type, numeric_type, character_type,
831 boolean_type, float_type) are added. These predicates are
832 based on the current value of working_lang, and are handy
835 Wed Jun 19 15:39:34 EDT 1991
837 eval.c Added the function type_array_rank which computes the rank
839 valarith.c Added the funtion value_bool, which when given a integer
840 value.h value (ie. struct value *) as an argument, it returns a
841 boolean value (ie. struct value *) true if that integer
842 is non-zero, and a boolean value false otherwise.
843 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
844 will print out properly.
846 Wed Jun 19 16:36:34 EDT 1991
848 valops.c Added the function value_capitalize, which returns it
849 value.h argument capitalized if its argument is a lowercase
850 letter, or the argument unchanged if its argument is not a
852 valarith.c Added the function range_check_p, which returns non-zero
853 value.h if its value argument is between the integral bounds upper
855 Added the function range_check_enum_p, which makes sure
856 that its value argument is a valid member of the domain of
858 Added the function range_check_range_p, which makes sure
859 its value argument lies between the upper and lower bounds
860 of its type argument, which must be a ranged type.
861 Added the function check_array_index, which range and type
862 checks an index of an array.
863 Added the function value_multi_subscript, which computes
864 array[idx1,idx2...idxN], given a value array and an array
865 of values representing indicies.
866 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
867 unpack_long to work with TYPE_CODE_BOOL and
870 Wed Jun 19 18:04:08 EDT 1991
872 symtab.c Stored pervasive types in a structure and make
873 lookup_pervasive_type() a lookup function that was based
874 on working_lang. If lookup_pervasive_type() returned
875 non-zero, then that value was returned (a fix, since
876 before it simply wouldn't return the pervasive type.)
877 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
878 non-zero if the language specified by working_lang means
879 "conversion" when it says "cast".
880 valops.c Added the function value_real_cast(), which performs a
881 value.h *cast*, not a *conversion*, which is what value_cast()
882 does when it can. In particular,
883 value_cast(<float_type>,4) = 4.0, while
884 value_real_cast(<float_type>,4) = some mess.
885 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
886 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
887 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
888 and MIN on integral types. *NOTE*: These are currently
889 hardcoded to work only if there are 8 bits per storage
891 eval.c Made logical functions call value_bool to return a
892 properly typed boolean value, based on working_lang.
894 Thu Jun 20 11:55:27 EDT 1991
896 valprint.c Types now print out in a Modula-2 fashion. This works for
897 the cases when the type is printed out step-by-step, that
898 is, it doesn't work when the name of a structured type
899 (which includes the keyword "struct", etc.) is simply
901 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
902 since type specifications in C and Modula-2 are very
903 different. The C printing of a type is very recursive,
904 whereas in Modula-2 it is generally very simple. C has
905 type prefixes and suffixes, which have no real analogue in
906 Modula-2. Maybe type_print() should call a language
907 specific type printer. This is also advantageous if we
908 compile GDB to exclude some of the languages. We'll just
909 leave those functions out.
911 Thu Jun 20 16:57:10 EDT 1991
913 dbxread.c When reading the complete symbol table in (via
914 psymtab_to_symtab()), the number and types of function
915 arguments are added to a function type. define_symbol()
916 calls add_param_to_type() to accomplish this.
917 Assumption: when we come across a function definition
918 (N_FUN symbol with an 'f' or 'F' in the name), its
919 arguments will appear before another function definition.
920 When a function is found, a pointer to its type is placed
921 in the global in_function_type. Changes that
922 add_param_to_type() makes are to this global.
923 valprint.c The type of a function now includes (for Modula-2) the
924 types of its parameters.
925 eval.c Type checking and a check for the proper number of
926 arguments is now done for function calls. Not sure of the
927 impact this has on C++ member function yet.
929 Thu Jun 20 19:58:48 EDT 1991
931 valprint.c Rewrote the type printer. Broke it into two language
932 specific parts, adding the functions type_print_m2() and
934 An unfortunate consequence is this: if you debugging a C
935 program in Modula-2 mode (why?), info types does not work
936 well with regular expressions, since the types are printed
937 out in Modula-2 terminology, but stored in C terminology.
938 language.[ch] Added the functions new_type_last(), type_keyword(), and
939 type_sep() to aid in the printing of typedefs.
940 symtab.c Made the printing of typedefs as language independent as
941 possible through calls to new_type_last(), type_keyword(),
944 Fri Jun 21 11:50:26 EDT 1991
946 dbxread.c Check all incoming ennumerated types. If it looks like
947 Modula-2's BOOLEAN type, then change the type_code of the
948 type to TYPE_CODE_BOOL so we can process it as a boolean
950 valprint.c Replaced some of the 0x%x with calls to sprintf and
951 hexformat() in val_print().
952 language.[ch] Added the function hex_to_string(), which converts its
953 integral argument to a hexadecimal number (format is
954 language based) and returns the result as a string.
956 Mon Jun 24 12:25:07 EDT 1991
958 valprint.c Some functions call type_print_1() directly, instead of
959 value.h using type_print(), so they can specify where (column) to
960 print things. Since type_print() takes care of language
961 dependence, that needs to be called first. Added a
962 parameter depth to type_print() (so it is now like
963 type_print_1). Changed type_print to type_print_at, and
964 made type_print a macro that passes a depth argument of
966 symmisc.c Changed all calls to type_print_1 to calls to
968 Makefile.dist Made it possible to build GDB for a specific set of
969 depend languages. Do this by passing a definition for the macro
970 LANGS to make. LANGS should be a string containing a
971 space-separated list of language names (ie. LANGS="c m2").
972 The default is to build all languages. Note that grammar
973 files must follow the naming convention of <lang>-exp.y.
974 gdb.lang This holds the current value of the LANGS macro. It is
975 examined every time make is called, and is updated if
977 eval.c Added #ifdef _LANG_<lang> to these files.
978 expread.c Still need to add them to dbxread.c and coffread.c.
986 Mon Jun 24 16:33:11 EDT 1991
988 language.[ch] Added the functions hexformat_pre() and
989 hex_to_string_pre(), which take a prefix argument to
990 include in the format string. Thus, hexformat_pre("08") will
991 return "0x08x" (if the working language is language_c).
992 Made hexformat() and hex_to_string() calls to the above
993 with "" as the prefix argument.

1003 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
1004 calls to hexformat() and hex_to_string(). Format strings without
1005 the leading "0x" were ignored.
1007 depend Updated to take the above into account.
1010 Tue Jun 25 15:27:18 EDT 1991
1012 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
1013 and type_check_t to keep track of the current state of
1014 range and type checking.
1015 main.c Added the variables range_mode, range_check, type_mode,
1016 and type_check to record the current state of range and
1017 type checking. Added initialization code to main().
1018 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
1019 the above variables.
1022 Tue Jun 25 17:57:08 EDT 1991
1024 dbxread.c process_one_symbol() updates the variable (enum language)
1025 source_lang based on the extension of the filename
1026 contained in the N_SO sybmol that started this symtab.
1027 When end_symtab() is called, the value of source_lang is
1028 put into the language field.
1029 stack.c select_frame() sets working_lang (and possibly type_check
1030 and range_check) to the language field of the symtab
1031 associated with the frame that is selected if working_mode
1032 is language_auto. If working_mode is language_manual, a
1033 warning is printed and working_lang is not set.
1034 language.c Added the function set_type_range(), which sets the value of
1035 type_check and range_check (if their modes call for
1036 automatic setting) based on the current value of
1037 working_lang. A non-zero argument will cause the current
1038 settings to be output.
1041 Wed Jun 26 14:51:40 EDT 1991
1043 eval.c Added range checks on assignment.
1044 m2-exp.y Added the grammar for sets to the language. Currently,
1045 these do not do anything except print an error message.
1047 Wed Jun 26 17:01:04 EDT 1991
1049 m2-exp.y Added the ability for parse_number() to parse negative
1050 numbers. A global flag is set upon encountering a unary
1051 minus. This was done to make, for example, 1 parse as a
1052 CARDINAL, and not as an integer, per Wirth's examples in
1053 Programming in Modula-2 ed.4.
1054 valprint.c Added support for "set radix 2" by then setting
1055 output_format to 't'.
1056 eval.c Implemented range checking on subrange types. Added calls
1057 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
1058 Implemented MIN and MAX for ennumerated types. The
1059 minimum value of an ennumerated type is defined by Wirth
1060 as the first identifier, and the maximum as the last.
1061 m2-exp.y Made octal numbers ending with "B" be characters and those
1062 ending with "C" be numbers, per Wirth's book. (p. 34)
1064 Thu Jun 27 14:11:52 EDT 1991
1066 stack.c select_frame() now only sets working_lang, it does not
1067 notify the user. If working_mode is language_manual, then
1068 a warning is issued once.
1069 main.c At the end of each call to execute_command(), working_lang
1070 is checked against the local static (enum language)
1071 current. If they differ and working_mode is
1072 language_auto, the new settings of language, type and
1073 range checking are printed out.
1074 stack.c Modified frame_info() to include the language of the
1075 current frame in the output of "info frame".
1076 language.[ch] Added the function language_str() which returns the name
1077 of the current language.
1079 Fri Jun 28 15:33:14 EDT 1991
1081 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
1082 the language. INCL and DECL currently cause an error,
1083 since sets are not implemented yet. INC and DEC are
1084 implemented as PREINCREMENT/PREDECREMENT with one
1085 argument, and as ASSIGN_MODIFY with two arguments.
1086 eval.c Added type checking to the above cases.
1087 value.h Added not_lval_constant to the lval_type ennumerated type.
1088 not_lval_constant means that the value is a constant
1089 value; that is 3 or 'a' or TRUE, not as in a constant
1090 identifier. This is used to help coerce numbers such as 3
1091 to either signed or unsigned numbers.
1092 valops.c Added the function value_coerce_constants() which coerces
1093 constant integers as following: if one is a constant and
1094 the other is not, the constant's type is set to the type
1095 of the other argument. If both are constants and one is
1096 signed, the other is converted to a signed constant.
1098 Sat Jun 29 17:26:29 EDT 1991
1100 valarith.c Added a better range checker. It now checks range
1101 (successfully) on integral operations [+-] (signed and
1102 unsigned) for any C sized type. Still does not work well
1103 for multiplication.)
1104 int_in_size() returns an integer that is coerced to fit into
1105 specified number of bytes.
1107 Mon Jul 1 13:04:14 EDT 1991
1109 language.[ch] Added the function binop_result_type(), which returns the
1110 builtin (struct type *) type that would be the result of a
1111 binop on the two values V1 and V2.
1113 Wed Jul 3 19:22:53 EDT 1991
1115 source.c Extended source_info() to include the source language in
1116 the output from "info source".
1118 Fri Jul 5 13:48:52 EDT 1991
1120 utils.c Moved the support functions for the GDB set/show commands
1121 dealing with language into language.c.
1122 language.c Added the function language_info(), which displays info
1123 about the current working language, type and range check
1124 settings. Called via the GDB command "info language".
1125 Added an initialization routine _initialize_language(),
1126 that sets defaults for the language, type and range
1127 variables and sets up the new GDB commands.
1128 main.c Language setup moved to language.c.
1131 Mon Jul 8 10:10:22 EDT 1991
1133 valarith.c Debugged the range checker for arithmetic. Still does not
1134 work for multiplication very well.
1136 Mon Jul 8 12:40:37 EDT 1991
1138 language.[ch] Added the function value_true() which returns non-zero if
1139 its argument represents a boolean true value.
1140 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
1141 check the truth of an expression.
1143 Thu Jul 11 12:51:34 EDT 1991
1145 language.[ch] Added the predicate structured_type(), which returns
1146 non-zero if the argument is a structured type.
1147 Added the predicate pointer_type(), which returns non-zero
1148 if the argument is a pointer type.
1149 eval.c Added the ability to do addition and substraction on
1150 pointers and integers. This case simply bypasses the
1153 Thu Jul 11 14:41:42 EDT 1991
1156 Added the symbol N_DEFD (0x4a) which is a definition
1157 module dependency that is used by the GNU Modula-2
1158 compiler and the linker. It is not important to GDB,
1159 except that [dbx|coff|mips]read.c should ignore these
1162 Fri Jul 12 16:07:00 EDT 1991
1164 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
1165 0 in val_print(). Also added statements to the else part
1166 to coerce type (argument to val_print) to a pointer type
1167 if it is an "array of unspecified length".
1168 valops.c Added the function value_m2_string(), which returns a
1169 (value) value which is a constant string, whose type is
1170 (ARRAY [0..n] OF CHAR). The length field of the type
1171 structure is set to zero, so it will be interpreted as an
1172 "array of unspecified length".
1173 stack.c Moved the language/frame mismatch check to
1174 main.c:execute_command().
1175 main.c The working language is recorded each time
1176 execute_command() is executed. If working lang has
1177 changed during its execution, then the new
1178 language/type/range info is printed out for the user. If
1179 the working language does not match the language of the
1180 frame, a warning is issued.
1182 Sat Jul 13 16:16:39 EDT 1991
1184 eval.c Moved all the type-checking stuff for operators to
1185 language.[ch] language.c. This is so we can keep language-specific
1186 stuff (like for what type operators are defined) in
1188 language.[ch] Added the function binop_type_check(), which checks to see
1189 if its two (value) arguments are type-compatible with its
1190 opcode argument. The opcode should represent an operation
1191 involving an operator. Also added the macro function
1192 unop_type_check, which calls binop_type_check with a
1193 NULL second argument.
1194 expprint.c Added Modula-2 operators to the op_print_tab, so info
1195 expression.h break works correctly. Also added "op_string", which
1196 returns the string corresponding to the (enum exp_opcode)
1197 opcode that is its argument.
1200 Sat Jul 13 18:26:18 EDT 1991
1202 coffread.c Added code to record the type of function arguments with
1203 each paricular function. Code is very similar to that
1205 dbxread.c Moved add_param_to_type() to symtab.c
1206 symtab.[ch] Added function add_param_to_type() from dbxread.c
1208 *** NOTE: The above additions have not been tested.
1210 Mon Jul 15 12:50:47 EDT 1991
1212 langauge.[ch] Added the functions type_error and range_error, which work
1213 like error() except if the type/range mode is set to
1214 *_mode_warn, then they do not do a return_to_top_level(),
1215 but merely print a warning.
1216 Also changed [set|show]_[type|range]_command() to support
1217 the new "warn" feature.
1219 Thu Jul 18 17:50:54 EDT 1991
1221 mipsread.c Added code to record the type of function arguments with
1222 each particular function. Code is very similar to that
1225 *** NOTE: The above additions have not been tested.
1227 Fri Jul 19 11:19:10 EDT 1991
1229 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
1230 UMIN_OF_SIZE, which when given a size of a numeric type,
1231 return the maximum and minimum value it can hold. UMAX...
1232 and UMIN... return the result for unsigned types.
1233 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
1234 struct types. They call above macros.
1235 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
1236 avoid a name conlict with the above.
1237 c-exp.y Added range checking on numeric constants in
1238 parse_number() for completeness.
1239 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
1240 return 0 if working_lang is not language_c.
1242 Thu Aug 8 14:17:22 EDT 1991
1246 breakpoint.c Documentation strings of some commands changed to
1247 eliminate the references to the C language where
1250 Tue Aug 13 15:48:03 EDT 1991
1252 m2-exp.y Added qualified identifiers to the grammar. The semantics
1253 are slightly different from those of the GDB operator ::
1255 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
1256 type_exp, where type_exp is any valid type expression.
1258 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
1259 printcmd.c Modified ptype_command() so it actually parses the input
1260 (necessary for type expressions with scope qualifiers).
1261 Added the function ptype_eval() which expects an
1262 expression composed of one OP_TYPE element.
1263 *.[ch] Replaced all occurences of parse_c_expression with
1265 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
1267 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
1269 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
1271 Small fixes from Peter Schauer:
1273 * infrun.c (child_attach): Lint.
1274 * solib.c (find_solib): Handle shared libs version 2.
1276 Small fixes from David Wood:
1278 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
1282 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
1283 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
1285 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
1286 chars_per_line is at maximum (user typed `set width 0'). Fix
1287 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
1289 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
1291 * coredep.c: include ptrace.h where necessary.
1292 * mipsread.c(parse_lines): fix unsigned char problem that was
1293 messing up line numbers on SGI's and possibly other MIPS based
1295 * infrun.c (child_create_inferior): use better test to check
1296 return val from setpgrp().
1297 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
1298 for sgi/irix support.
1300 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
1302 * mipsread.c (parse_symbol): Put non-static procedures
1303 in the global block.
1305 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
1307 Patch together `text_start' and `text_end' for 29K port.
1309 * exec.c (exec_command): If NEED_TEXT_START_END, define the
1310 variables and set them based on the exec file.
1311 * am29k-tdep.c: declare text_start.
1312 * valops.c (call_function_by_hand): declare text_end.
1314 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
1315 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
1316 because machines that do this will also have to know to
1317 set NEED_TEXT_START_END. Besides, it was a redundant way to
1319 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
1320 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
1321 NEED_TEXT_START_END.
1323 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
1325 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
1327 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
1328 Pass MUNCH_DEFINE to munch whenever we run it.
1329 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
1330 format string; use 0x%x instead.
1331 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
1332 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
1333 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
1334 * inflow.c: Handle `short' process group IDs.
1335 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
1336 and check for ptrace errors.
1337 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
1338 (coff_symfile_init): Initialize text_bfd_scnum.
1339 (read_coff_symtab): Use it to find the text [and absolute?] sections.
1340 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
1341 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
1342 Merge target arm case with other "easy" cases. Add target
1343 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
1344 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
1346 * minimon.h, remote-adapt.c, remote-mm.c: Add.
1347 * munch: Cope with RT/PC putting fns in data segment.
1348 Restore ability to override `nm' by specifying MUNCH_NM.
1349 * xconfig/rtbsd, xconfig/ultra3: New host systems.
1350 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
1351 and remote-adapt. Remove encapsulated coff #define's (the
1352 support should go in BFD, and gdb shouldn't know or care).
1353 * tconfig/a29k-kern: Same, but for remote kernel debugging.
1354 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
1355 * tm-29k.h: Update BADMAG (though it should go away).
1356 Allow the register definitions to be overridden in another
1357 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
1358 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
1359 DUMMY_SAVE_GR96, for handling kernel calling conventions
1360 that use GR64+ rather than GR96+.
1361 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
1362 remote debugging of Ultra3 kernel. Includes tm-29k.h and
1363 overrides various things.
1365 * remote-mm.c (mm_attach, mm_wait): Handle attach like
1366 child_attach does, making a clean stop in the newly attached
1368 * remote-eb.c: Lint.
1370 * coffread.c: Make coffread independent of any particular
1371 variant of COFF. Avoid #include-ing any particular one except
1372 internalcoff.h. BFD now passes key values for symbol reading
1373 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
1374 and the symbol masks and shifts); use them.
1375 Remove obsolete end_of_text_addr.
1377 * exec.c: Remove unused include files.
1379 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1381 * Makefile.in (documentation targets): Pass $(M4).
1382 Bugfix from eggert@twinsun.com (Paul Eggert).
1384 * stack.c (down_silently_command): Check for stack existence.
1386 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1388 * Makefile.in (VERSION): Update to 4.0.3.
1390 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1392 * core.c (core_file_command): Print frame at coredump with
1393 its level number, by calling print_stack_frame.
1394 * frame.h: Add selected_frame_level, print_stack_frame.
1395 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
1396 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
1397 Change print_sel_frame and print_selected_frame callers to
1400 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
1401 * symfile.c (free_named_symtabs): Ditto.
1402 * main.c (main): wrap_here needs an arg.
1403 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
1404 (solib_add): Avoid noise.
1405 (solib_create_inferior_hook): Lint.
1406 (sharedlibrary_command): Move dont_repeat to here.
1407 * utils.c (error): Call wrap_here to force buffered output.
1409 Small patches from Peter Schauer:
1411 * coffread.c (start_symtab): Free any existing line_vector before
1413 (read_coff_symtab): Ditto for type_vector.
1415 * source.c (lines_to_list): New variable, replacing function.
1416 (all uses): Use as variable.
1417 (_initialize_source): Add 'set listsize' and 'show listsize'.
1418 * utils.c (lines_to_list): Remove function.
1419 * stack.c (print_frame_info): Use as variable.
1420 * defs.h (lines_to_list): Remove declaration.
1422 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1424 * breakpoint.c (insert_breakpoints): Restore warning about
1425 the program might be running in another process, but only for
1426 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
1427 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
1429 * utils.c (error): if error_pre_print is set, print the string
1431 * main.c (main, print_gnu_advertisement, print_gdb_version):
1432 Reformat legalese so it always prints, but acts as an "I'm here"
1433 message while symbols are being read. If any errors occur,
1434 print a few newlines to set off the message and start it at the
1435 left margin. Remove mention of "help" command, and don't yak
1436 about symbol reading.
1437 (catch_errors): Error string is now printed first in case of
1439 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
1440 suggest the "help" command.
1442 * Makefile.in (VERSION): Set to 4.0.2.
1444 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
1446 * .gdbinit: Remove useless "rr" command. Set complaints
1447 to 1 for people debugging gdb.
1449 * breakpoint.c, remote-vx.c: Reword strings printed by
1450 catch_errors callers.
1452 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
1454 * WHATS.NEW: "history write -> history save". Doc "write on/off".
1455 (Fix from kenc@viewlogic.com.)
1457 Fix some infrastructure to be able to cope with host and target
1458 machines with different sized basic types (ints, ptrs, etc).
1459 (Idea from pierre@la.tce.com (Pierre Willard).)
1461 * values.c (value_from_longest): Rename from value_from_long.
1462 Handle pointer types as well as integers, so that targets with
1463 different pointer sizes from the host can be accomodated.
1464 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
1465 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
1466 uses of value_from_long to value_from_longest.
1467 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
1468 the correct pointer type to value_from_long{est}.
1470 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
1472 * remote-vx.c: Remove obsolete code for calling functions via
1473 vxworks kludge interface (it referenced value_from_long).
1475 * valops.c (value_string): Find malloc with lookup_misc_func, not
1478 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1480 Make writing to files work properly. (Fixes to BFD are also needed.)
1482 * core.c (core_open): Open file ourselves, read or r/w, depending on
1483 write_files. Use bfd_fdopenr.
1484 * gdbcore.h (write_files): New variable.
1485 * exec.c (write_files): Define variable, add set&show for it.
1486 (exec_file_command): Use write_files to open for read or r/write.
1488 Make shared library reading happen automatically. These changes
1489 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
1491 * inferior.h (stop_soon_quietly): Add to exported variables.
1492 * infrun.c (child_create_inferior): call solib hook, if defined.
1493 (child_attach): call solib hook, if defined.
1494 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
1495 (find_solib): Use lookup_misc_func rather than hand-rolled.
1496 (symbol_add_stub): New stub for catch_errors.
1497 (solib_add): Avoid output if !from_tty. Catch errors rather
1498 than just calling symbol_file_add and bombing.
1499 (solib_create_inferior_hook): Interface with the target process
1500 to let it read and alloc shared libs, then figure out what it did.
1502 * core.c (validate_files): Fix typo, soften warning.
1503 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
1505 * utils.c (fputs_demangled): Avoid duplicate printing if
1506 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
1508 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
1509 (Fix from pierre@la.tce.com (Pierre Willard).)
1511 * main.c (catch_errors): Change argument to a char * from an int,
1512 since a char * can point to a struct full of glop, but an int
1513 is not guaranteed to be able to hold a pointer.
1514 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
1515 breakpoint_re_set_one, breakpoint_re_set): Adapt.
1516 * core.c (core_open, solib_add_stub): Adapt.
1517 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
1519 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1521 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
1522 by adding .NOEXPORT target.
1524 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1528 * Makefile.in (VERSION): Roll to 4.0.
1529 (gdb.tar.Z): Make refcard.ps as well, for shipment.
1531 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1533 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
1536 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
1539 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
1541 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
1542 reflect above name change
1544 * WHATS.NEW: correct pointer to refcard.
1546 * doc/gdb.texinfo: update New Features, Installing
1548 * doc/gdbint.texinfo: add short description of configure +template
1550 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1552 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
1554 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
1556 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
1557 tar file, add dependencies for referenced doc files.
1559 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
1561 * coffread.c, symfile.c, stack.c: saberized.
1563 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1565 * doc/refcard.tex: permuted Essential Commands sec
1567 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
1569 set/show symbol-reloading
1570 default set complaints 0
1572 RET-repeat disabled after prompted long displays
1573 processID (attach) interpretation of 2nd GDB cmdline arg
1575 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
1577 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
1578 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
1579 breakpoint.c, main.c: lint.
1581 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1583 Install new configuration scheme for GDB and friends.
1585 * config.sub: Translate ordinary names to three-part names.
1586 * configure: Use three-part names internally.
1587 * configure.in: Translate three-part names to filenames.
1589 * README, WHATS.NEW: Update for gdb-4.0.
1590 * Makefile.in: Roll VERSION to 3.99.
1592 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
1594 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
1595 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
1596 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
1597 to single structures rather than arrays; when passing
1598 their address, use &. This avoids trouble with bdead compilers.
1599 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
1600 instead. This avoids portability headaches.
1601 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
1603 * source.c (open_source_file): Avoid ANSI const bdeath by
1604 skipping declaration and then casting result value.
1605 * tm-hp300bsd.h: Clarify comment.
1606 * utils.c (strstr): Result is const char *; ANSI bdeath.
1607 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
1608 since system include file defines it differently from "defs.h",
1609 though the two are equivalent for our purposes.
1610 * tconfig/hp300bsd: Add m68k-tdep.o.
1612 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1614 * tconfig/sun*4: Remove warnings about system assembler.
1616 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1618 * mcheck.c: Avoid warning about undeclared abort fn.
1619 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
1620 it causes recursive calls to error() when used in cleanups.
1621 To do so requires that we make it a function, so we do.
1622 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
1623 * utils.c (do_cleanups): Remove the current cleanup from the
1624 chain *before* calling it, in case error() is called from it.
1625 The result won't be pretty, but won't be an infinite loop either.
1627 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
1629 * dbxread.c (read_struct_type): Grok anon structs for C++.
1630 (vb_name, vptr_name): Null terminate these strings.
1632 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1634 Minor bug fixes from BSD Net2 gdb:
1636 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
1637 returns 0, there is no previous frame.
1638 * breakpoint.c (commands_command): If !from_tty, don't call
1639 input_from_terminal_p().
1640 * dbxread.c (record_misc_function): Speed up slightly.
1641 (compare_psymbols): Ditto.
1642 * infcmd.c (do_registers_info): Take a second argument to
1643 determine whether to print float registers. "info registers"
1644 does not do so anymore. "info all-registers" does, now.
1645 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
1647 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
1648 * inflow.c (initialize_inflow): Set tflags_ours correctly.
1652 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
1653 executing_breakpoint_commands if we are interrupted by error.
1654 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
1655 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
1656 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
1657 catch_errors() so we can setup the frame regardless of whether
1658 the shared libs work.
1659 * ieee-float.c (double_to_ieee_extended): Get exponent from
1660 right place in little-endian systems. From John Carey.
1662 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1664 * main.c: Remove unused terminating_signals and catch_termination().
1665 (long_options): Terminate with a zero element.
1666 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
1667 (gdb_readline): Make call-compatible with readline.
1668 (init_signals): Improve comments re vfork vs. signal.
1670 * utils.c (prompt_for_continue): Use new gdb_readline().
1671 If we prompt for continuation, we don't let CR repeat the previous
1672 command, once we get back to a prompt. It's too easy to keep
1673 hitting CR, expecting "--more--" prompts, and have some long
1674 command start repeating on you.
1676 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1678 * blockframe.c (frameless_look_for_prologue): Speed up by
1679 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
1680 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
1681 Define two variants, one faster.
1682 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
1683 and return zero, rather than giving an error.
1684 (setup_arbitrary_frame): Initialize the PC in the new frame.
1685 (skip_prologue): Add a second arg saying whether we're just
1686 checking for a frameless function or not.
1688 * core.c (core_open, core_close, core_xfer_memory): Move
1689 section table pointers and bfd* into the target_ops.
1690 (core_open): Allow errors in shared lib reading, etc.
1691 (core_files_info): Describe shared library sections.
1693 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
1694 exec_files_info, set_section_command): Move section table
1695 pointers and bfd* into the target_ops.
1696 (add_to_section_table): Add BFD to section table.
1698 * target.c (target_xfer_memory, target_info): Pass target to
1699 xfer_memory and target_info functions.
1702 * gdbcore.h: Move struct section_table.
1703 * target.h: New home of struct section_table.
1705 * solib.c (solib_add): New argument is the target_ops whose
1706 section list is to be added to, if any. Reallocate the
1707 sections in that target to add any that come from shared libs.
1708 (throughout) so_sections renamed to sections.
1709 (solib_xfer_memory): Deleted.
1710 * tm-sunos.h (SOLIB_ADD): Add target argument.
1711 (SOLIB_XFER_MEMORY): Delete.
1713 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1714 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
1715 from target_ops. It's the same on all targets. Add two section
1716 pointers to target_ops.
1718 * stack.c (find_relative_frame): Dump ancient algorithm for
1719 "down", just use handy "next" pointers.
1720 (frame_command): Don't error if there is no stack; let user
1723 * inflow.c (new_tty_prefork, new_tty): New prefork routine
1724 modifies static state in the parent process; new_tty itself
1725 runs in the child and modifies the child's file descriptors
1726 to match the saved static state.
1727 * infrun.c (child_create_inferior): Call new_tty_prefork,
1730 * infptrace.c (child_xfer_memory): Add ignored target arg.
1731 * remote-eb.c (eb_xfer_inferior_memory): ''
1732 * remote-nindy.c (nindy_xfer_inferior_memory): ''
1733 * remote-vx.c (vx_xfer_memory): ''
1734 * remote.c (remote_xfer_memory): ''. Rename from
1735 remote_xfer_inferior_memory.
1737 * main.c (main): Only try to attach "corefile" argument if
1738 it starts with a digit.
1740 * symfile.c (symbol_reloading): New "set/show" variable.
1741 (symbol_file_add): Shorten message about symbol reading.
1742 (add_symbol_file_command): Merge with add_syms_addr_command,
1743 since this should work on all targets now.
1744 (stop_whining): Default to zero, to shut up complaints
1745 about bad symbol tables on many systems.
1746 (free_named_symtabs): Just exit unless symbol_reloading.
1748 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
1749 and add comment explaining shared library screw.
1751 * source.c: #if defined => #ifdef.
1753 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1755 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
1757 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1759 * doc/rdl-apps.texinfo: provide default readline-appendix finder
1760 (doc/Makefile knows how to make one for local config)
1762 * Makefile.in: use doc/Makefile for doc targets
1764 * doc/Makefile: GDB documentation now has its own Makefile
1765 doc/refcard.tex: renamed from "gdbrc.tex"
1766 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
1767 doc/gdbint.texinfo: add markup in "Cleanups" chapter
1770 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1772 * values.c (baseclass_addr): When reading target memory, use the
1773 length of the basetype, not the upper type. We've only malloc'd
1774 enough space for the basetype, leading to errors in free().
1776 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
1777 ends up as a function specially, since we know the actual type of
1778 the pointed-to address. This (somewhat) fixes display of
1779 expressions that include misc_function_vector names. Try `cond 1
1780 !strcmp("a","b")' then `i b'.
1782 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
1783 The child can be proceeded from inside wait_for_inferior in
1784 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
1785 getting skipped in that case.
1787 * expprint.c (print_subexp): Use filtered output, since the
1788 subroutines we call use it, otherwise the output is horribly
1789 mangled, since output of wrappable stuff comes out late.
1791 * Makefile.in: Bump VERSION to 3.98.1
1793 * infrun.c (child_create_process): Use execlp to find the
1794 shell to exec our target program. This requires some fiddling
1795 with `environ' since there is no execlpe().
1797 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1799 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
1800 Minor rearrangement of refcard permits two new make targets--
1801 gdbrc.dvi DVI output for refcard, using CM fonts
1802 gdbrc.ps PostScript refcard, using PS fonts
1804 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1808 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
1809 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
1811 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1813 * doc/gdb.texinfo: last changes for release.
1814 Minor typo and formatting fixes; incorporated most fixes remaining from
1815 filed mail commenting on earlier drafts.
1817 Added warnings: pipes don't work in run command;
1818 conditions are converse of assertions;
1819 step over fn without debug info goes to next fn;
1820 vars may have "wrong" values near fn entrance, exit
1822 Added example from Kingston on printing repeated nonadjacent values
1824 Added explicit mention that in Emacs gdb mode C-c and C-z are like
1825 shell mode for signals
1827 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
1828 doesn't sound so much like its parent "Stopping and Continuing"; also
1829 moved entries on continue to top of section, so they don't get lost.
1831 Improved installation directions in appendix, added manual formatting
1834 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1836 * configure.in: Remove xm.h and tm.h even if we aren't linking
1837 new ones, so "./configure sun4; ./configure none" does the right
1838 thing. Assume that alldeps.mak and depend are already built in
1839 srcdir, and avoid running "make" (particularly "make depend",
1840 which involves "gcc") from inside configure. Build Makefile
1841 directly rather than building Makefile.conf first.
1842 * configure: Regenerate with above changes.
1843 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
1844 to 3.98. Revise gdb.tar.Z procedure to produce a file
1845 called gdb-$(VERSION).tar.Z but which unpacks into a
1846 directory called "gdb". Move non-source files out of
1847 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
1848 (depend): Don't try to do "gcc expread.y".
1849 (expread.o): Update dependencies by hand.
1851 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1854 Fixed a variety of small typos that prevented info from formatting
1855 cleanly; altered too-long heading for GPL Appendix, as discussed
1856 w/RMS; Changed date on cover to July 91.
1858 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1861 (1) Applied some fixes due to comments from Larry Breed (easier ones
1862 through chapsec 5.2)
1863 (2) Eliminated use of @footnote---had my doubts about it anyways, and
1864 it's broken in latest texinfo
1865 (3) Introduced *some* use of [] for optional arguments, where
1866 explanation is not simpler by listing cmd w arg and cmd w/out arg
1867 separately. Still not using @deffn.
1868 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
1869 couple of headings are too long. Need patches to texinfo or revision
1872 * Partial update to README (which still needs work for this
1873 release!): (1) use of configure corrected for new script,
1874 (2) "make gdb.dvi" and "make gdb.info" mentioned.
1876 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
1878 * symtab.c (lookup_symbol): Don't complain right off about
1879 no debug symbols; use the misc function vector first.
1880 (list_symbols): Use misc function vector to find symbols
1881 that don't have debug info, and print them.
1882 (find_pc_symtab): Temporarily avoid fatal() when psymtab
1883 PC range doesn't match symtab PC range, as it does on the
1884 MIPS because our symtab reading isn't perfect.
1886 * dbxread.c (dbx_symfile_read): Make warning about
1887 "no debug symbols" slightly nicer.
1889 * source.c (select_source_symtab): If "main" symbol exists,
1890 but decode_line_spec can't find line info, don't just return
1891 a zero; try other source symtabs or give an error.
1893 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
1894 their low addresses first, then rip through fixing high addrs.
1896 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
1897 <runene@ifi.uio.no>.
1898 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
1900 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1902 * Minor, mostly mechanical, cleanup of doc subdir for clean
1903 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
1904 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
1906 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
1908 Mostly MIPS and general symbol-reading fixups.
1910 * doc/gdbint.texinfo: Add documentation on symbol-reading
1913 * mipsread.c: Remove kludges around #include "ecoff.h".
1914 Remove redefinitions of a_magic, etc, no longer used.
1915 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
1916 Fix global overview comments to match symfile.c protocol.
1917 (mipscoff_new_init): Eliminate cur_hdr if we have one.
1918 (mipscoff_symfile_read): Eliminate unused code. Avoid
1919 sorting all the symtabs, when all we have read here is psymtabs.
1920 The symtabs are sorted as they are created anyway. Tell
1921 condense_misc_bunches whether we're mainline.
1922 (psymtab_to_symtab_1): Pass filename when recursing, to make
1923 stack trace more informative.
1924 (parse_partial_symbols): Assume cur_hdr as argument.
1925 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
1926 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
1927 the TYPE_NAME of char *, since that's done in symfile.c.
1928 (free_numargs, parse_symbol, add_symbol, add_block,
1929 shrink_linetable): Declare these fns void.
1930 (upgrade_type): Convert tree of if's to switch. Clean up
1931 bogus "off == 0" handling with a complaint. Avoid setting
1932 field bitpos and bitsize of array with lower and upper bounds.
1933 Check specified bitsize of elements against their actual type's
1934 bitsize, and complain if different. Complain about unknown
1936 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
1937 (psymtab_to_symtab_1): Print names of subsidiary files that
1938 are being read in. FIXME, we read far too many files. This code
1939 is not the problem, the problem is in parse_fdr where the psymtabs
1941 (cross_ref): Result should indicate that we used one aux entry
1942 normally, or two if we encountered a "next" entry. This used
1943 to leave the caller pointing at the wrong aux entry.
1944 (add_symbol): If overflowed cur_block, reallocate it larger,
1945 chase all pointers to it, and complain(), rather than clobber memory.
1946 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
1947 (new_field): Only allocate one field initially, not two.
1948 Pull ++ out of macro argument. Simplify.
1949 (_initialize_mipsread): Avoid initialization of importd
1950 global_psymbols and static_psymbols.
1952 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
1953 to properly set pst->symtab; avoid searching for it.
1954 (symfile_fns): Improve comments, add a FIXME.
1955 * dbxread.c: Update comments to reflect symfile protocol.
1956 (read_ofile_symtab, end_symtab): Return the symtab.
1957 (psymtab_to_symtab_1): Set pst->symtab.
1959 * coffread.c (coff_symfile_read): tell condense_misc_bunches
1960 whether we're mainline.
1962 * symfile.h (sym_fns): Remove unused sym_discard member.
1963 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
1965 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
1966 the environment variable is not.
1967 * infcmd.c (finish_command): Use filtered printfs.
1968 * cplus-dem.c: Add struct tags to a few unnamed structs.
1969 * valops.c (value_coerce_array): Improve comments.
1970 * valprint.c (type_print_varspec_suffix): Print array size only
1971 if greater than zero.
1972 * m88k-tdep.c: Shift some lines left by one space, that had
1973 apparently been trashed at some point.
1974 * TODO: More things to do, a few got done.
1976 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1978 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
1979 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
1981 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
1982 * expread.y, findvar.c, symmisc.c: Ditto.
1983 * printcmd.c (address_info): Update printed forms of LOC_
1984 symbols. Elim LOC_EXTERNAL.
1985 (print_frame_args): Keep track of param stack offsets before
1986 re-looking up to find the local register param is kept in.
1988 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
1989 Further integration of mipsread into gdb. Eliminate unused
1990 routines, duplicate declarations. Handle static symbols in
1991 psymtabs as well as external symbols. When reading symtabs,
1992 insert symbols into the correct block (global, static, or a local
1994 (read_mips_symtab, parse_partial_symbols): Don't pass useless
1996 (mipscoff_symfile_read): Don't call select_source_symtab.
1997 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
1998 rather than SYMBOL_VALUE.
1999 (parse_external): Comment clobbering of top_stack.
2000 (parse_partial_symbols): Update comments. Allocate and parse
2001 static symbols as well as external symbols. FIXME, enum values
2002 are not handled in this pass, but should be. Inline new_psymbol.
2003 Use SYMBOL_VALUE_ADDRESS.
2004 (psymtab_to_symtab_1): Read symbols into global static block
2005 by default (until enter some function's local block context).
2006 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
2007 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
2009 * source.c (select_source_symtab): Select a source symtab
2010 from either the symtabs or, failing that, the psymtabs.
2011 (list_command): Update error message.
2012 (forward_search_command, reverse_search_command): Use getc, not
2013 fgetc, for speed. FIXME, add comment about buffers that die if
2014 overrun by long line.
2016 * values.c (unpack_field_as_long, modify_field): Avoid shifting
2017 by an entire word, which is not portable, if we have a 32-bit
2018 field. (Code in dbxread.c already turns such bitfields, if
2019 aligned, into ordinary ints, but fixing this will help for other
2020 symbol formats and for future changes.)
2021 * core.c (core_open): Handle ANSI const brain death.
2022 * utils.c (vprintf): Fix varargs typo.
2024 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
2026 * findvar.c (find_var_value): Handle &function better.
2027 * TODO: Document work needed on &fn and &array.
2028 * printcmd.c (print_address_symbolic): New arg is the prefix
2029 to print if a name is printed.
2030 (print_address_demangle): Honor "set print address" now.
2031 Use new arg above to improve spacing of output.
2032 * valprint.c (val_print): When printing function pointers,
2033 print symbolic form too.
2034 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
2036 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2038 * core.c (memory_error): Reword error msg to mislead less.
2040 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
2042 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
2043 parse_partial_symbols): Use newer BFD internals (external_filehdr
2044 and external_aouthdr), byte-swap the fields that we care about
2045 before using them, and make the file header data local to
2046 read_the_mips_symtab rather than global.
2048 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
2050 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
2051 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
2053 * main.c (command_line_input): Flush stdout and stderr
2054 before every call to readline. This reportedly fixes a bug
2055 that comes up in Sys V running emacs-gdb and/or xxgdb,
2056 when stdin/out are pipes or sockets.
2058 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2060 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
2061 Avoid declaring Makefile dependencies, because GNU Make stupidly
2062 tries to update it if we do.
2064 * coffread.c: Revise for minor changes to bfd internal coff
2067 * configure: If -template= is given a relative path, make it
2068 absolute before recurring in subdirectories.
2070 * configure, configure.in, Makefile.in: Install "configure" script
2071 as replacement for config.gdb.
2072 * config.gdb, Makefile.dist, Makefile.sdir: Remove
2073 * README: Update for configure, mostly. FIXME.
2075 * Add dec3100 as equivalent to littlemips. Indicate in all host &
2076 target config files that they are for the host. When the lines
2077 get copied into the Makefile, this makes it more obvious what's
2080 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2082 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
2083 tabs, which end up in the disassembler output inadvertently.
2085 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
2087 Make it compile cleanly in an ANSI GCC2 environment.
2089 * blockframe.c: <stdio.h>
2090 * cplus-dem.c: free takes a void *, ifdef __STDC__
2091 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
2093 * defs.h (alloca): Avoid doing anything if alloca already def'd.
2094 * stddef.h, stdlib.h: Remove these files.
2095 * symtab.c: Avoid declaring qsort, close.
2096 * symfile.c: Avoid declaring close.
2097 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
2098 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
2100 Assorted other changes.
2101 * dbxread.c: include "libaout.h", not "liba.out.h".
2102 * printcmd.c (print_frame_args): Set recurse properly for
2103 indentation of struct and array parameters.
2104 * valops.c (value_cast): Allow cast to void.
2105 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
2106 single_step() in a target-independent fashion.
2107 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
2108 set up to be ready to continue. This makes us target independent.
2109 * infptrace.c (child_resume): Remove call to single_step; now
2110 can single step a SPARC target of any kind.
2112 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2114 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
2115 docn into separate sections---basically chapters, plus two loose
2116 pieces that can be configured to go in different places. This
2117 allows GNU m4 to preprocess the manual without coredumping.
2119 * Makefile.dist: tell TeX where to find texinfo.
2121 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2123 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
2124 the new target "rdl-apps.texinfo" which captures the Makefile
2125 variable that records where to find the Readline libraries.
2127 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
2129 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
2130 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
2131 * defs.h (const, volatile): Only define if not already defined.
2132 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
2134 * README: Update for release 3.95.
2135 * config.gdb: Don't create readline dir in subdir builds.
2136 * main.c: Include with "..." form for non-system include files,
2137 so "gcc -MM" for "make depend" works.
2138 Include readline files with "...h" rather than <readline/...h>.
2139 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
2141 * coffread.c: Undo minor damage done by Rich Pixley. Use
2142 different internal and external representations of COFF
2143 data structures. Use new BFD routines for swapping them in and
2145 * symfile.c (free_named_symtabs): Avoid freeing file names that
2146 are null or empty. Old i960 tools seem to produce files that
2147 claim to have empty names, causing each successive file read
2148 to blow away the previous one.
2149 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
2150 Move deferred_stores to top of file, but don't separate its
2151 #define's from its variable. Add commentary.
2152 * Makefile.dist: Fix Rich damage; undo "configure" changes in
2153 favor of keeping the (working) config.gdb. Move readline
2156 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
2158 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
2160 * infptrace.c (fetch_registers): no result, since now void.
2161 * tconfig/news: target depends on m68k-tdep too.
2163 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2165 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
2168 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
2169 applied various small fixes due to or inspired by RMS comments
2171 * doc/gdb.texinfo: finished using all RMS comments, save those for
2172 appendices on readline and cmd history (which are in other source
2175 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2177 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
2178 chapter 9; (2) documented 'break' command's menu mode for
2179 overloaded names, in response to hgs problem report C++ p-31
2181 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2183 * doc/gdb.texinfo: (1) better introductory example; (2) more
2184 consistent use of @code, @samp, @file, @kbd throughout; small
2185 cleanups to first three nodes; (3) new "Contributors" node;
2186 (4) Appendix, Renamed Commands; (5) divert specialized startup
2187 instructions to "Targets" chapter for generic manuals, while
2188 leaving them up front for manuals specific to specialized
2189 environments; (6) apply fixes from RMS comments through chapter 4.
2191 * pretex.m4: modify explanatory text slightly (and redefine
2192 "regexp") to keep GNU m4 from complaining. (It still crashes
2193 later, but one step at a time...)
2195 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
2197 * readline/readline.c (update_line): Avoid dereferencing a pointer
2198 before comparing it to its bounds. Saber caught this.
2199 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
2200 and only set PC if tgetstr returned non-null. Saber caught this.
2202 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2204 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
2205 stuff for config manual) here where it counts; updated
2206 to use new subdir structure (gdb/doc/).
2208 * Makefile: generated from above via
2212 * gdbint.texinfo: added instructions on generating gdb.info* files
2213 locally for release. These are ordinary info
2214 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
2215 Makefile)---but due to use of texinfo 2, can't count on makeinfo
2216 to generate these, so we distribute them already formatted.
2218 * gdb.texinfo: included full Info node and menu crud (as generated
2219 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
2221 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
2222 put in comments-for-future gdb.info target (one day makeinfo will
2225 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2227 * gdb.texinfo: Updated to include new or old undocumented
2228 commands, at least the following (perhaps some others I forgot to
2229 record): info f, info float, info path, info program, info s, info
2230 set, info source, info terminal, info types, info user, set/show
2232 Also covered all recent GDB command renames for v4.
2234 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2236 * mipsread.c: Rather than keeping count of how many symtabs
2237 and psymtabs we have, for sorting purposes, count them when
2238 we need to sort. This fixes bug in rereading of symbol tables.
2240 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2242 * infcmd.c: renamed "info path" to "show paths"

2256 * coffread.c, exec.c, infptrace.c, inftarg.c, remote.c, solib.c,
2257 symtab.h, target.c, target.h: Lint.
2258 * core.c: setup and select frame after reading shared libs,
2259 else reading shared libs will clobber them. Lint.
2260 * utils.c (error): Force out any buffered wrap text.
2262 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2264 * remote.c: Remove decls of memory_insert_breakpoint
2265 and memory_remove_breakpoint, no longer used. (Suggestion of
2268 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
2269 to make it easier to interface to "configure"'d libraries.
2271 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
2273 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
2274 aliases for set/show print.

2330 * coffread.c [TDESC]: Move setting of debug_info from
2331 coff_symfile_read to find_linenos and make it work with BFD.
2333 * cplus-dem.c [__STDC__]: Make x{m,re}alloc return void*.
2335 * signame.c: Cast const char* to char* when assigning to sys_siglist.
2337 * utils.c (strsave): Make arg const char* not char*.
2339 * infrun.c (wait_for_inferior) [SHIFT_INSN_REGS]: Use

2360 Mips bringup and general cleanup
2362 * cplus-dem.c: Move CPLUS_MARKER define to after defs.h.
2363 * infptrace.c (PT_WRITE_D, PT_READ_D): Use correct values.
2364 (This still doesn't seem to make MIPS bkpts work.)
2365 * mipsread.c: Remove dup "Reading symbol data..." msg.
2366 (symbol_file_command, add_file_command): Remove, obsol.
2367 * printcmd.c (ptype_command): Say "an enum" rather than "a enum".
2368 Wrap output appropriately.

2370 selected_frame rather than target_has_stack or coredumping.
2371 * valprint.c (type_print_varspec_suffix): Wrap "ptype" output of
2372 enums appropriately.
2374 Wed May 1 14:10:22 1991 Jim Kingdon (kingdon at cygint.cygnus.com)

2383 can have both ints and enum type_pieces in it.
2384 ({push,pop}_type_int): New functions.
2386 Tue Apr 30 13:18:58 1991 Jim Kingdon (kingdon at cygint.cygnus.com)

2398 symtab.c, cplus-dem.c, value.h, expread.y, valprint.c,
2399 copying.awk, solib.c, inflow.c, symmisc.c
2400 : Lint. Use read_memory not read_memory_integer on CORE_ADDR's.
2401 Use {value_as,unpack}_pointer (added to values.c)
2402 not {value_as,unpack}_long on CORE_ADDR's.
2403 Use longest_to_int (added to defs.h) instead of cast to int.
2404 Remove from_tty arg to mod_path.
2405 Put symfile_bfd in {coff,dbx}read.c not symfile.h.
2406 Use OP_NULL instead of 0 where dummy enum exp_opcode needed.

2894 * i386-pinsn.c: Move #includes to top, remove useless ones.
2895 * i386-tdep.c: Don't bother including <.../reg.h> since we
2896 don't use it (and it doesn't exist on host systems).
2898 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
2899 Convert negative numbers properly.
2900 (ieee_test): Make numbers really random; fix format arg.
2902 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
2903 * core.c (core_detach): Unpush core_ops, which might not be on
2904 top. We used to just pop the top, which broke things. Don't
2905 need dont_repeat() any more.
2906 (core_file_command): Psst! Don't repeat it.
2907 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
2908 * expprint.c (print_subexp): Avoid switch fallthru on
2909 BINOP_ASSIGN_MODIFY, so we can print += and such.
2910 * frame.h: Fix typo.
2911 * inflow.c (kill_command): After killing inferior, print our
2912 current frame in the core file, if we have one.
2913 (generic_mourn_inferior): When inferior dies, either select
2914 the current frame (in the new target, e.g. core file), or
2915 set both the current and selected frames to NULL.
2917 Changes from Peter Schauer.
2919 * infptrace.c: Avoid <sys/ptrace.h> on USG.
2921 * Make all file names fit in 14 characters (sigh and damn!):
2922 mv hp300hpux-xdep.c hp300ux-xdep.c

2930 mv remote-sa.m68k.shar rem-m68k.shar
2931 mv remote-multi.shar rem-multi.shar
2932 * Makefile.dist, README, config.gdb, convex-pinsn.c,
2933 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
2934 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
2937 * command.c (user_info_1, user_info): New command for listing
2938 the user-defined commands.
2940 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
2942 * dbxread.c (really_free_pendings): Clear file_symbols
2943 and global_symbols after freeing them; otherwise, running
2944 this function twice (if it appears twice on the cleanup
2945 chain), we try to free things twice.
2947 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
2948 based on text_addr (the address of text in core), not on addr (the
2949 offset between text in the .o file and in core). This change
2950 is from Peter Schauer.
2952 * main.c: Define ALL_CLEANUPS as a cast of zero.
2953 (return_to_top_level): Use it.
2954 (main): Do all cleanups after each command run as part
2955 of the gdb startup sequence. Also do all cleanups before
2956 entering the command loop, and every time we exit the command
2957 loop and reenter. Before, the cleanups from the startup sequence
2958 were being left undone until the first error!
2959 (command_loop): Rename do_nothing cleanup to command_loop_marker
2960 so we can see it easily when examining the cleanup chain.
2961 (init_signals): Add another do_nothing for signal handling.
2962 (quit_command): Only try to kill target if it has execution.
2963 Problems in the target stack got us into a state where
2964 inferior_pid was nonzero but none of the targets had execution.
2965 In this state you couldn't exit gdb.
2967 * dbxread.c: Two changes from Peter Schauer.
2968 (echo_command): Fflush output after an echo command.
2969 (show_history): Pass all args to cmd_show_list.
2971 * utils.c (init_malloc): Call mtrace to turn on tracing
2972 if the environment variable MALLOC_TRACE is set to a file name.
2973 * mtrace.c: Add source file which provides a log of every malloc,
2974 free, and realloc to a trace file.
2975 * mtrace.awk: Add source file which analyzes the trace file.
2976 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
2977 (VERSION): Roll to 3.94.3.
2979 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
2980 (check_duplicates): Don't bother with watchpoints.
2981 (set_raw_breakpoint): Comment about danger of this routine.
2982 (watch_command): Parse and eval all args before calling
2985 * solib.c (find_solib): Avoid error in referencing memory to
2986 see if any more shared libraries have been added. This is
2987 particularly useful if the target has terminated. Bug reported
2990 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
2991 in bringing up 3.94.2 on the Sun-3.
2993 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
2994 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
2995 expression (in scope) before reenabling watchpoint.
2996 * signame.c (init_sigs): Add missing declaration of i, fix
2997 sys_siglist declaration.
2998 * source.c (list_command): Fixed range computation to use
3000 * stack.c (backtrace_command): Do not allow command if target has
3001 no stack, print informative error message.
3002 * target.c (target_command): Do not write into command line
3003 because this fails if the target command is used in a user defined
3004 command. [This change was enhanced by gnu to support any-
3005 unique-prefix matching on target names.]
3006 * valops.c (value_struct_elt): Avoid infinite loop on an
3007 erroneous attempt to print the member of function (try p main.p).
3009 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3011 * expread.y (name_no_typename): Avoid reduce/reduce errors
3012 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
3013 Since the GDB parser really doesn't use name_no_typename in a
3014 name-only context, the parser can't tell the diff between
3015 names and numbers here. Avoid allowing a name_no_typename
3016 to be a NAME_OR_*INT to resolve the conflict.
3018 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3020 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
3022 * valprint.c (val_print_fields): bitfield printing didn't handle
3023 byte order. Indirect through a few more fns to cope.
3025 * values.c (modify_field): also cope with byte order.
3027 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
3029 Cleanup for release 3.94.2:
3031 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
3032 include files. Roll version to 3.94.2.
3034 * coffread.c (init_stringtab): Read length into unsigned char
3035 array before swapping; don't assume 32-bit longs.
3037 * target.c (target_info): Don't bother with get_sym_file, just use
3038 the symfile global variable.
3039 * symtab.h, symfile.c (get_sym_file): Delete it.
3041 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
3042 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
3043 (read_type): Replace one more error() with complain().
3045 * mipsread.c (parse_partial_symbols): Replace printf with complain.
3047 * i960-tdep.c: Fix copyright attribution.
3049 * config.gdb: Quote all backquotes in doublequotes. You can
3050 quote me on that. BSD 4.4 shell found this one.
3052 * infptrace.c (throughout): The third argument to ptrace is an
3055 * infrun.c (wait_for_inferior): When program has terminated, we
3056 have to call target_terminal_ours before we pop that target off
3057 the stack (e.g. before a call to target_kill or
3058 target_mourn_inferior). This fixes problem where a program
3059 terminates, then GDB stops for (tty output) and you have to type
3060 "fg" to the shell to resume it. FIXME: This code for what to
3061 do after termination really should be in normal_stop instead.
3063 * gdbcore.h (read_memory_check): Change declaration; it changed
3066 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
3067 4.4 prereleases, this avoids a bug in their sgtty compatability
3069 * remote.c: Use terminal.h rather than hand-rolling the same.
3071 * signame.c, signame.h (psignal): Arg is unsigned, not int.
3072 * utils.c (strsave, strstr): Fix arg types.
3073 * valprint.c (val_print): lint
3075 MIPS symbol table support from Per Bothner:
3077 * symfile.c (symtab_fns): Remove initializer table that needs to
3078 be hacked for each new symbol file format supported.
3079 (add_symtab_fns): New function, chains symbol table
3080 handlers into the global list.
3081 (symfile_init): Search this list.
3082 * symfile.h: Add next pointer, declare add_symtab_fns.
3083 * coffread.c (_initialize_coffread): Call add_symtab_fns.
3084 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
3086 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
3087 symbol *). Thus, we no longer need the hack to trash
3088 pst->filename. Good, since that hack confused code in symfile.c!
3090 (reorder_symtabs, destroy_all_symtabs): Removed static
3091 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
3092 Instead, the latter now uses a temporary array (stack-allocated
3093 from an obstack, and then freed).
3095 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
3096 haven't been set in the outermost stBlock of a procedure. This was
3097 a problem with f77 binaries on Ultrix 4.?.
3099 (new_symtab, new_symbol, new_type): Continue changing code to use
3100 obstacks more and otherwise conform to dbxread internal style.
3101 Made the free_code of symtabs be free_linetable (as in dbxread)
3102 instead of free_contents. This implies memory leaks when reading
3103 a new symbol table, until the conversion is finished. Did change
3104 (struct symbol) and (struct type) to be allocated on the
3105 symbol_obstack. Blocks and blockvectors are among the things
3108 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
3109 tested much, but it solved one problem (reported by Meissner), and
3110 cleans up some other things. The problem happened when an
3111 included file contains actual code (functions) and not just
3112 definitions. The mips coff is a little inconvenient there, since
3113 it may cause a procedure to be mapped to the wrong psymtab.
3115 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
3116 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
3117 this will need work for the new core paradigm.
3119 Opcode patches from the net:
3121 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
3122 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
3123 missing altogether - they are added here. From Bruce Bauman.
3124 * mips-opcode.h: The low mask for C0 instructions was too small.
3125 From Garrett Lau. I modified the fix to check the entire 32-bit
3128 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
3131 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3133 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
3135 * dbxread.c (read_type): Pointer subtraction (value_sub in
3136 valarith.c) sometimes failed because the types of the
3137 pointers being subtracted were not identical.
3138 These differed because dbxread.c was allocating pointer types
3139 using dbx_alloc_type+smash_to_pointer_type instead of
3140 lookup_pointer_type. I failed to find a justification for the
3141 former, so I changed it to use the latter. Similarly, I
3142 replaced smash_to_function_type by lookup_function_type,
3143 and smash_to_reference_type by lookup_reference_type.
3145 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
3146 _initialize_mipsread): corresponding changes.
3148 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
3150 * source.c (mod_path): Do tilde_expand on each component of the path,
3151 rather than on the (list of) paths as a whole.
3152 (print_source_lines): Set first_line_listed in addition to
3153 current_source_symtab and current_source_line. If the source was
3154 not findable, after a "dir" command to fix the problem,
3155 a "list" would get the wrong lines.
3157 While I was there... (gnu):
3159 * dbxread.c (read_type): Change error to complaint.
3161 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3163 First attempt at detailed understanding of symbol table memory alloc.
3165 * dbxread.c (dbx_symfile_read): Free our string table if we
3166 aren't the mainline. Free the "info" struct since we're done with
3168 (init_psymbol_list): Free any previously allocated psymbol lists.
3169 (): FIXME: Should realloc-down the psymbol lists when done reading
3170 the main symbol file?
3172 * symmisc.c (free_symtab): Free fullname field too.
3174 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
3175 (REGISTER_ADDR): Make result type unsigned int.
3177 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
3178 define REGEX must also define REGEX1 (its dependency).
3180 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
3182 * tconfig/i960: No longer works, points you at vxworks960 or
3185 * xgdb.c, XGDB-README: Remove file. Users can get the much
3187 * Makefile.dist: Remove all trace of xgdb.
3189 * breakpoint.c (breakpoint_1): Pass demangle arg to
3190 print_address_symbolic.
3191 (clear_breakpoints): Remove unused function.
3192 (breakpoint_re_set_one): Guts of breakpoint_re_set.
3193 (breakpoint_re_set): Use catch_errors to do them all anyway.
3195 * gdb-int.texinfo (Host versus Target): Add section on what is
3196 a "host" feature versus what is a "target" feature.
3198 * infcmd.c (path_command, path_info): Handle the PATH variable
3199 (object search path) as conveniently as the source search path.
3200 * environ.c (set_in_environ): Set some vars in GDB's environment,
3201 in addition to the child's. PATH, G960BASE, G960BIN for starters.
3202 * source.c (mod_path): New function, from guts of
3203 directory_command, modifies a path. Used by path_command.
3204 (directory_command): Call it.
3205 * defs.h (strsave): Declare.
3207 * utils.c (sevenbit_strings): Add new printing option.
3208 (printchar): Use it.
3209 (strsave): Provide this handy helper routine.
3210 (set_width_command): Rename set_screen_width_command.
3211 (_initialize_utils): "set screen-width" => "set width";
3212 "set screen-height" => "set height"; add sevenbit-strings.
3214 * infcmd.c (do_registers_info): Print floating point registers
3215 in raw hex as well as float format, regardless of whether it is
3216 a "virtual" convertible register.
3217 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
3218 regs as a double, just in case it's being used that way.
3219 * values.c (unpack_long): Comment on array/function coercion.
3220 (unpack_double): Argument is in target byte order now. For
3221 integer arguments, just call unpack_long and float the result.
3222 * m68k-tdep.c: include defs.h for "const" handling.
3223 * remote-nindy.c: Use ieee-float stuff.
3224 (nindy_fetch_registers): Unpack double regs to host double, then
3226 (nindy_store_registers): Pack extendeds to host double, flip
3227 around by misusing unpack_double, send as target double.
3229 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
3230 zero, as when stopped at the first instruction of a process.
3232 * blockframe.c: Fix filename in comment (param.h => tm.h).
3233 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
3234 * tm-68k.h: Fix typos.
3236 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
3238 Changes from a bringup on the DEC Vax under Ultrix 4.0.
3240 * coredep.c (fetch_core_registers): Pass end-address of register
3241 section to register_addr as expected. Don't call supply_register
3242 if we'd just pass it garbage.
3244 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
3246 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
3248 * target.c (push_target, target_info): Cast enums to int for < or
3251 * stack.c (print_frame_info): Identify source file & line
3252 even if we can't print it.
3254 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
3256 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
3258 Clean up IEEE floating point support.
3260 * ieee-float.h: New file.
3261 * ieee-float.c: Write real routines to convert between host
3262 doubles and various target IEEE extendeds.
3263 * m68k-xdep.c: Eliminate assembler code for extended floats.
3264 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
3265 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
3266 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
3267 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
3268 double_to_ieee_extended.
3269 * i960-tdep.c: Define ext_format_i960.
3270 * m68k-tdep.c: Define ext_format_68881.
3271 * sparc-tdep.c: Define ext_format_sparc, though unused.
3272 * Makefile.dist (HFILES): Add ieee-float.h.
3273 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
3276 Obsolete the "coffstrip" program in favor of using BFD's strip.
3278 * nindy-share/coffstrip.c: Remove file.
3279 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
3280 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
3281 * tconfig/nindy960: Remove reference to coffstrip.o.
3283 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
3285 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3287 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
3288 * dbxread.c: Remove static symfile_bfd.
3289 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
3291 * inftarg.c (child_detach): Pop the child_ops vector if the
3292 detach is successful.
3293 * remote-nindy.c (nindy_create_inferior): Don't push a new
3294 nindy_ops since nindy uses the same one for execution and memory
3296 * core.c (core_ops): Use child_attach and child_create_inferior
3297 rather than default attach and create_inferior functions.
3299 Handle floating point registers in core files.
3301 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
3302 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
3303 This version untested since BFD doesn't yet support sun3 core
3305 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
3306 conventions. Fix comments and style. This version has not
3307 been compiled yet, since we have no HP inhouse.
3308 * core.c (get_core_registers): Look for two sections, ".reg"
3309 and ".reg2", and pass both to fetch_core_registers sequentially.
3311 Revise directory path yet again.
3313 * source.c (forget_cached_source_info): Not static any more.
3314 (init_source_path): New default source path is "$cdir:$cwd".
3315 (dir_command): Handle variable arguments ($cdir, $cwd).
3316 (source_info): Print "Compilation directory" rather than
3317 "Originally compiled in" to remind people of $cdir.
3318 (openp): If the path contains $cwd, use current directory.
3319 (open_source_file): If compilation directory is known, replace
3320 first $cdir in path with the compilation directory.
3321 (print_source_lines): Even if we can't print the lines, set the
3322 current symtab and line for future commands like "info source" or
3323 "breakpoint". Also, error message now contains the file name,
3324 line number, and file access error message.
3325 (_initialize_source): Fix help text to describe changes.
3326 * main.c (cd_command): Forget cached source info when we chdir.
3327 * utils.c (strstr): Add simple implementation.
3329 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
3331 * coffread.c (read_one_sym, init_linetable, init_stringtab):
3332 Byte-swap COFF symbol tables if necessary when reading them in.
3333 Use complain() to replace error message in one spot. Needs
3334 corresponding change in bfd/coff-code.h to make some symbol
3335 swapping routines non-static.
3337 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3339 Merge changes from Eirik Fuller, for UTek.
3341 * defs.h (errno): Add declaration.
3342 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
3343 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
3344 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
3345 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
3346 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
3347 declarations of errno.
3349 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
3351 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
3352 <rpc/rpc.h> and <rpc/types.h>.
3354 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
3356 * i960-tdep.c (examine_prologue): Add new argument limit,
3357 which stops the scan at the end of the prologue, or at the PC.
3358 This fixes a problem where it walks down into the code for the
3359 user's statements if that code looks like function prologues.
3360 Mark Fox and I have been bouncing this code back and forth, making
3361 small changes to it. Callers changed to match.
3363 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
3365 Cleanup for gdb-3.94 release final:
3367 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
3368 the .c files from vx-share and nindy-share, from the various
3369 macros, since they are not found via ALLDEPFILES.
3370 (SFILES): Add tm-i960.h.
3371 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
3372 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
3374 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
3375 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
3377 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
3379 * am29k-tdep.c: Add contribution line.
3380 (examine_prologue): Cache information about function prologues in
3381 the misc-function-vector to avoid lots of references over the
3382 serial line while examining instructions.
3384 * core.c (core_close): New function made from cleanup_core.
3386 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
3387 remote-vx.c, remote.c, target.c, target.h,
3388 Update target_ops vector to add attach, close, and load entries.
3389 Use add_syms_addr_command, not add_file_addr_command, for
3390 add_file. Break out close routine from existing code.
3392 * dbxread.c (really_free_pendings): Don't free pending_blocks;
3393 they are in an obstack.
3394 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
3396 (define_symbol): Add symbol type parameter; change callers;
3397 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
3398 it to influence the symbol class on the i960.
3399 (define_symbol): Swap LOC_CONST's into target byte order.
3401 * exec.c (exec_close): New function.
3402 (exec_file_command): Call it.
3404 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
3405 Fix byte order of frame pointer.
3406 (read_var_value): Result of 0 if var's value can't be found,
3407 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
3408 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
3409 (locate_var_value): Use read_var_value and use its lazy address
3410 as the location of the var's value. Lint.
3412 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
3415 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
3416 obsolete Intel versions in favor of vxgdb versions.
3417 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
3418 code dealing with byte order of values, which Intel did in host byte
3419 order rather than gdb-4's target byte order.
3420 (i960_frame_chain_valid): Move to nindy-tdep.c.
3421 (examine_prologue, skip_prologue, frame_find_saved_regs,
3422 frame_args_address, leafproc_return, saved_pc_after_call,
3423 pop_frame): Add vxgdb versions from Mark Fox.
3424 (examine_prologue, frame_struct_result_address): Add code
3425 to deal with the saved value of G13 (struct return address
3427 (frame_args_address): Modify Mark's version to prefer the
3428 saved value over the current value in the topmost frame.
3429 Cache result in the frame info to avoid performance hair in
3431 (print_fault): Add gdb960 code for printing faults.
3432 (_initialize_i960): Actually call check_host.
3434 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
3435 add stub routines. FIXME, these currently just return zero!
3437 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
3438 (attach_command): Call target_attach, not target_open, now.
3440 * infrun.c (normal_stop): Make global, not static, for vx_attach.
3441 (child_attach): Rename from child_open.
3442 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
3443 don't confuse it with a zero step_resume_break_address.
3445 * inftarg.c (child_detach): Eliminate inferior_pid test.
3446 (child_files_info): Clean up message a bit.
3447 (child_ops): Use child_attach, not child_open, to attach.
3449 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
3450 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
3451 findvar.c to here, since it depends on the contents of the
3452 shadow_contents of breakpoints, but keep if #if 0 since it is
3455 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
3458 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
3459 (ptype_command, display_command): Eliminate have_inferior_p and
3460 have_core_file_p in favor of target_has_stack or
3461 target_has_execution.
3462 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
3463 code for actually finding the values of arguments, though we still
3464 keep track of the maximum stack offset for use in printing unnamed
3465 arguments. Handle missing FRAME_ARGS_ADDRESS.
3467 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
3468 (struct nindy_regs): Define registers passed to/from nindy.
3469 (nindy_fetch_registers, nindy_store-registers): Translate between
3470 nindy and GDB formats for the registers.
3471 (dcache_init): Statically allocate the cache, since it was being
3472 allocated by a malloc that was never freed anyway.
3473 (nindy_create_inferior): Error, not core dump, if no exec file.
3474 (nindy_before_main_loop): Use target_load, not target_add_file.
3476 * remote-vx.c (net_load): Specify large timeout for load
3477 requests. Allow user to break out with INTERRUPT.
3478 (net_break): Remove useless code, clean up. Change callers.
3479 (parse-args, skip_white_space, find_white_space): Clean up arg
3480 parsing to cope with quoted strings.
3481 (net_wait, net_quit): Never call error, just return status.
3482 (vx_read_register, vx_write_register): Cleanup status checking.
3483 #ifdef the code based on which CPU we are using (960 or 68k),
3484 FIXME, this should be completely general but it isn't yet.
3485 (vx_xfer_memory, vx_resume): Cleanup status checking.
3486 (vx_run_files_info): Improve message.
3487 (vx_load_command): Renamed from vx_add_file_command. Allow load
3489 (net_ptrace): Remove unused routine.
3490 (vx_wait): Adopt code from vxgdb960 to cope with broken
3491 connections to target machine and prompt to disconnect. Remove
3492 debug printouts. Map some EVENT_'s to SIGnals.
3493 (add_symbol_stub, vx_open): Print names of object files we found,
3494 and "ok" if we read their symbols OK. Clarify output in general.
3495 (vx_attach, vx_detach, vx_kill): Add these commands.
3496 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
3497 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
3498 "info files" output, and create_inferior, since we already have
3501 * stack.c (frame_info): Replace Frame_unknown with 0.
3502 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
3503 (return_command): Pop until the PC matches as well as the FP,
3504 so it works even if the FP is shared with another function,
3505 as in "frameless" or "leaf" procedures.
3507 * symfile.c (load_command): renamed from add_file_target_command.
3508 (add_syms_addr_command): renamed from add_file_addr_command.
3509 (add_syms_command): Stub to call target_add_syms.
3510 (_initialize_symfile): Change command names and descriptions,
3511 add-file => add-syms, and load from alias to its own command.
3513 * target.c (kill_or_be_killed, maybe_kill_then_attach,
3514 maybe_kill_then_create_inferior): Default for attempts to start
3515 a process, if one is already running, is to ask about killing
3516 it and retry if yes.
3517 (upstack_create_inferior): #if-0 it, strata obsolete it.
3518 (push_target, unpush_target, pop_target): to_close() a target
3519 before unstacking it.
3520 (target_info): Renamed from target_files_info.
3521 (_initialize_targets): Rename "i files" as "i target", accessible
3524 * target.h: Improve comments about the target_ vectored routines.
3526 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
3527 Convert commenting style to standard GNU style.
3528 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
3529 (SKIP_PROLOGUE): No longer a no-op.
3530 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
3531 (*_REGNUM): Sort register numbers.
3532 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
3533 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
3534 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
3535 are now 10 byte extendeds, not 8 byte doubles.
3536 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
3537 for nindy versus vxworks targets. FIXME, this should possibly go
3538 in the target vector.
3539 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
3540 frame_saved_regs and arg pointer with each frame.
3541 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
3542 (FRAME_ARGS_ADDRESS): Use cached result.
3543 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
3544 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
3545 (PRINT_RAMDON_SIGNAL): Call print_fault.
3546 (POP_FRAME): Now works.
3548 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
3549 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
3550 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
3551 (ADDITIONAL_OPTION_HANDLER): use target_load, not
3554 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
3555 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
3557 * valarith.c (value_subscripted_rvalue): Avoid handling
3558 floats and doubles specially; it gave alignment errors. Lint.
3560 * valops.c (value_of_variable, value_of_this): Error if unknown
3563 * valprint.c (print_floating): Bcopy rather than pointer-deref,
3564 to avoid alignment problems.
3565 (value_print): Handle unknown value address.
3566 (cplus_val_print): Two args are ignored; remove them. Change caller.
3567 (val_print): Use unpack_long rather than pointer-deref.
3570 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
3571 to avoid alignment problems.
3572 (value_being_returned): Error if return value unknown.
3573 (set_return_value): Add bogosity warning, FIXME. *
3575 * TODO: A woman's work is never done.
3577 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
3578 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
3579 Add ieee-float.o to OBS.
3580 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
3581 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
3582 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
3584 Changes to generalize the VxWorks RPC protocol slightly, to handle
3585 i960 as well as 68000.
3587 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
3588 * vx-share/reg.h: Produce i960 regs #ifdef I80960
3589 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
3590 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
3591 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
3592 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
3593 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
3594 so they will move in target byte order rather than network
3595 byte order (happens to be the same).
3597 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
3599 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
3601 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
3604 Add contribution lines to various files, showing where they
3607 * breakpoint.c (break_insn, check_break_insn_size,
3608 read_memory_nobpt): Remove to mem-break.c.
3610 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
3613 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
3614 entry has bad register number. This change is not
3615 tested in this release, FIXME.
3617 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
3620 * value.h: Force value's contents field to be aligned to hold
3621 at least a double or a long long (if supported). This avoids
3622 doing bcopy's in and out of the contents field.
3624 (step_1): Avoid coredump under obscure circumstances when we
3627 * symtab.h (misc_info): Add field to misc function vector for
3628 any kind of cached information the target code desires. AMD
3629 29000 uses this to avoid repeating examine_function_prologue's.
3631 * coffread.c: Lint. Remove static symfile, read_section_header.
3632 core.c (have_core_file_p): Lint: remove.
3633 expprint.c (print_subexp): Lint.
3634 infptrace.c, valops.c, valprint.c: lint.
3636 Roll in changes from vxgdb-5.0.1:
3638 * symtab.h: Comment byte order of each address class. Add
3639 LOC_LOCAL_ARG for frame-relative args (960).
3640 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
3641 symtab.c, symmisc.c: ditto.
3643 * infrun.c (init_wait_for_inferior): Clear stop_signal.
3645 * remote.c (remote_resume): Error if resume with a signal.
3647 * symfile.c (prim_record_misc_function): Clear misc_info.
3648 (fill_in_vptr_fieldno): Check stub type of arg.
3650 * valops.c (value_cast): Avoid looking up names of types whose
3651 name we don't know, to prevent coredump. Sun CC produces typedef
3652 rtx and the name of *rtx is zero...
3654 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3656 Roll in changes from final AMD 29000 port (Tiemann).
3658 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
3659 for ../include/a.out.encap.h. This might not work now that BFD
3660 is separately compiled. Instead, BFD support for encap will have
3661 to translate machine type 29k into the right COFF_MAGIC.
3663 * infcmd.c: Remove references to inferior_pid that aren't used
3664 in actual ptrace calls; use target_has_execution, etc.
3665 (have_inferior_p): Remove function.
3666 (program_info): Print target info rather than "process number";
3667 avoid gratuitous messages unless from_tty.
3668 (run_stack_dummy, finish_command): Set proceed_to_finish.
3669 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
3670 main.c: Lint. Lose have_inferior_p().
3671 inferior.h (have_inferior_p): Remove, lint.
3672 (proceed_to_finish): Add flag to ask that all regs be saved
3673 by normal_stop, for the few commands that need it, speeding up
3674 serial I/O. Add comments to stop_registers.
3676 * remote-eb.c: Remove newline from breakpoint message we grep
3677 for. Never time out when running the user program.
3681 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3683 Roll in changes from vxgdb-5.0.1:
3685 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
3686 symbol in its raw form, we are processing an unlinked ".o" file.
3687 See if the target environment has assigned it an address, using
3688 target_lookup_symbol (VxWorks does), and enter it into the symtab
3691 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
3692 68k versions for a simpler version that assumes zero FP at bottom.
3693 Fixes bug of truncated stack reports.
3695 * target.h (target_lookup_symbol): Define this routine's args
3696 and result, finally.
3698 * target.c (nosymbol): Default routine for target_lookup_symbol.
3699 (target_default): Default lookup_symbol and call_function too.
3700 (files_info): Only print has_all_memory warning if a non-dummy
3703 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
3704 vx_convert_from_virtual): If target does not have floating point,
3705 zero register "values", and avoid doing cross-net conversions.
3706 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
3707 (vx_open): Rearrange code that attaches to target and reads
3708 symbols for all loaded modules, to work if some of the modules
3709 are not accessible. Add symbol_stub() and add_symbol_stub()
3710 as callbacks from catch_errors(). Allow connect attempt to be
3711 interrupted painlessly with ^C (FIXME, there are still some bugs
3712 if the interrupt happens during symbol reading.). Print
3713 final message with puts_filtered, since symbol messages are
3718 * main.c (catch_errors): Only print errstring if non-null.
3719 (command_loop): Avoid an ioctl per command to test ISATTY.
3721 * remote-vx.c (net_load): make static; avoid sophomoric msg.
3722 (vx_xfer_memory): Return correct result!
3723 (vx_files_info): Indicate whether target has float or not.
3724 (vx_lookup_symbol): Complain, not error, if target gone.
3725 (vx_open): Print "Connected" msg before disabling immediate-quit.
3726 [FIXME: lookup_symbol and vx_open changes need testing.]
3728 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
3729 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
3730 contributor lines and update copyrights to 1991.
3732 Changes from an attempted H-PUX host port:
3734 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
3735 defines PT_ATTACH and PT_DETACH but not PT_KILL.
3736 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
3737 * remote-vx.c: include <sys/time.h> for HPUX.
3738 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
3739 "core_file_command" routine to BFD regime. May not work yet.
3741 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
3743 * xgdb.c: Replace X10 version with some VJ version.
3744 (FIXME: Its copyright assignment is not on record.)
3745 * xgdb.c: Update include files to X11R4 (Xaw crud).
3746 (xgdb_display_source, create_text_widget): fix call to
3747 get_filename_and_charpos. Rewack source window stuff for X11R4
3748 (gleaned from include files, and "nm's" of binary libraries, since
3749 I had no doc available).
3750 (append_selection, append_selection_word): Disable with FIXME
3751 since R4 changed interface here.
3752 (create_buttons): Add back the old set of buttons.
3753 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
3755 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
3756 Roll VERSION to 3.94 (not yet final though).
3758 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3760 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
3761 obstack_int_grow, obstack_int_grow_fast): Eliminate
3762 cast on left of assignment, which gives MIPS cc fits and is
3765 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
3766 F_ALIAS. Use printf, not fprintf, when not passing a file
3768 (compare_opcodes): Check that identical instructions have
3769 identical opcodes, complain otherwise.
3771 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
3772 was reported by Roland McGrath.
3773 (unimp): Only match if exactly zero instruction. (Roland)
3774 (branches and traps): Generate all variations of these
3775 instructions with macros, based on a single call that defines
3776 each condition name and its binary representation.
3777 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
3779 * valprint.c (val_print_fields): Take, and use, format parameter.
3780 This means that "p/x struct" again prints the elements in the
3781 desired format. Changed callers.
3783 * stack.c (frame_info): Use filtered output, and indicate wrap
3784 points. Remove kludgy formatting designed to avoid line wrap.
3786 * utils.c (wrap_here): If the line is already full (because
3787 we had printed a long indent or long wrapped string), do an
3788 immediate newline-and-indent.
3790 * m68k-pinsn.c (print_insn_arg): Bugfix from
3791 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
3792 instruction is incorrectly disassembled as bkpt #8.
3794 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
3795 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
3796 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
3797 and then will dump core (sometimes). I traced it back to an
3798 uninitialized symfile_name in psymtab_to_symtab.
3799 (const_vol_complaint): Add quotes to message.
3800 (define_symbol): Only believe line number if gcc_compiled.
3801 Avoid allocating symbol if we will not return it.
3803 Add target strata support so that newly established targets go
3804 into their right place in the target stack (e.g. a new exec file
3805 doesn't wipe out the ability to access the running process).
3807 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
3808 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
3809 and initialize it properly in all the targets.
3811 * target.h: Document strata. Change return type of push_target.
3813 * target.c (nomemory): new function for dummy memory access.
3814 (tcomplain): Rename complain, now also used in symfile.c.
3815 (push_target): Push targets within strata. New return value shows
3816 whether new target is on top of stack or not. Always keep dummy
3818 (target_files_info): Ignore dummy target.
3820 * core.c (core_open): Warn user, and skip accessing file, if the
3821 core target is not the topmost target in the stack.
3822 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
3825 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
3826 target_ops, it doesn't belong there since we have no regs there.
3827 Change name of target from machine => memory to clarify.
3829 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
3831 * Freeze version 3.93 for release.
3833 * Makefile.dist: Handle vx-share and nindy-share subdirs
3834 properly when building gdb.tar.Z.
3836 * symtab.c: lint; add no_symtab_msg to consolidate the messages
3837 printed in various places, so I could change just one copy.
3839 * dbxread.c, coffread.c: Change references to bfd->iostream
3840 to cast to FILE *, now that BFD avoids needing types defined
3841 in other header files.
3843 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3845 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
3846 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
3847 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
3848 (actually gcc -Wall).
3850 * dbxread.c: Remove first_global_sym, last_global_sym, since
3851 they are never referenced.
3853 * defs.h (baud_rate): Declare.
3854 main.c: Define it, and add the -b option to set it.
3856 * gdb-int.texinfo: Add text on how to define a new host or target
3857 architecture, prompted by Per Bothner's questions about MIPS
3860 * gdb.texinfo: Document "complaints". Change doc of -q since
3861 gdb no longer prints the copyright and blurb if you specify a file
3862 name to be debugged (just like Emacs). Add doc for Nindy-specific
3863 command line flags for specifying target serial port and such.
3864 Update copyright to 1991.
3866 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
3867 has taken over for us the job of ripping up executable files. The
3868 crud caused Per Bothner's port to not compile.
3870 * infrun.c (normal_stop): Avoid printing "Program exited
3871 normally" if we are in batch mode. This allows a GDB which
3872 executes a program on a target system, to behave like a Unix
3873 command (input from stdin, output to stdout, no extraneous
3876 * main.c (main): Allow additional machine-dependent command line
3877 options to be specified with the ADDITIONAL_OPTIONS,
3878 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
3879 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
3880 processing to occur just before the main loop with
3881 BEFORE_MAIN_LOOP_HOOK.
3882 (main): If a "core file" argument is specified, and it is not a
3883 core file, try it as a process ID to attach.
3884 (symbol_completion_function): Attempt to cope with
3885 "show screen-" TAB, not very successfully. This needs more work,
3887 (batch_file): New function, returns whether we are reading
3888 commands from an interactive tty on stdin, or from somewhere else.
3889 Called by normal_stop since it doesn't get from_tty passed down
3890 to it like many commands do.
3892 * remote-nindy.c: Handle command line options for nindy
3894 (nindy_before_main_loop): Prompt user for tty name if they
3895 don't specify it before getting to the interactive command loop.
3897 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
3898 and -r command line options. Also add hook before main loop
3899 to make it easy to specify a tty.
3901 * TODO: More things to do, one done.
3903 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
3905 * dbxread.c: Make complaint() calls pass pointer, not struct.
3906 Add complaints about badly formatted C++ type information
3907 (const/volatile indicator, and parse errors resulting in
3908 error_type). Fix C++ virtual member fn comment.
3909 (read_struct_type): Avoid bumping pointer if we got a parse
3910 error; this prevents our walking beyond the end of a string.
3911 Terminate loop on null char as well as semicolon.
3912 (process_one_symbol): Fix the LBRAC fix so that it uses the
3913 last previous SLINE, FUN, or SO record's PC address. C++ debug
3914 symbols did not have SLINE records in a useful order compared
3915 to the LBRAC records.
3916 (define_symbol): Handle "catch" records.
3918 * symtab.c (check_stub_type): Added new complain
3919 `stub_noname_complain' and added a consistency check to
3920 keep the debugger from crashing when finishing from an
3921 exception frame. A real fix will be needed later.
3923 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
3925 * infcmd.c (attach_command): Make global.
3927 * Makefile.dist (REMOTE_OBS): Make these compile by default,
3928 but make them easy to comment out. Perhaps later they should
3929 be enabled by what CPU you configure for? FIXME.
3930 (VERSION): Roll to 3.93.
3931 (pinsn.o): Remove rule for obsolete file.
3932 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
3934 Run down a problem that manifested by printing the wrong function
3935 name in stack traces of read_ofile_symtab. Turned out that the
3936 problem was the SunOS 4.1.1 (and previous) C compiler outputs
3937 the LBRAC symbol with an address in the *data* segment, which
3938 blew our binary search through the blocks.
3940 * dbxread.c: Use the complain() facility consistently to bitch
3941 about problems in the symbol file we are reading.
3942 (finish_block): Add code to check the nesting of the blocks;
3943 complain and Procrust them to fit if wrong.
3944 (make_blockvector): Check the order of the blocks, complain
3945 [but don't cope] if wrong.
3946 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
3947 symbols to be sure their PC value is greater than the last SLINE
3948 (line number) symbol we've seen, complaining and adopting the
3949 SLINE PC value if wrong.
3951 * symfile.h (struct complaint, complaint_root, complain,
3952 clear_complaints): Add.
3953 * symfile.c (complain, complaint_root, clear_complaints): Add
3954 facility to deal with non-fatal complaints and to regularize their
3956 (symbol_file_add): Clear complaint counters to allow new complaints.
3957 (initialize_symfile): Add 'set complaints' and 'show complaints'.
3959 * dbxread.c (dbx_symfile_read): Remember the address and size
3960 of the string table for the main symbol file, so we won't read it
3962 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
3963 to avoid reading the string table yet again. Lint.
3964 (throughout): Improve filtered output, including word wrap.
3965 (read_range_type): Improve Bothner's fix to handle other types too.
3967 * utils.c: Improve line wrap implementation. Handle unlimited
3968 width by making chars_per_line unsigned.
3969 (puts_filtered): New, easy, function.
3971 * defs.h (puts_filtered): add.
3973 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
3974 call the identical sort_symtab_syms() in symfile.c instead.
3976 * expread.y: Suggest the `file' command rather than `symbol-file'.
3978 * command.h (enum var_types): Add zinteger for seroable
3980 * command.c (do_setshow_command): Handle var_zinteger. Restructure
3981 nested if's into a switch.
3983 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
3984 we did not stop because of a breakpoint (it must have been for
3985 some other reason, like a "stepi"), so don't print anything.
3987 * symtab.c: Include <sys/types.h> all the time. Now that BFD
3988 doesn't include <sys/types.h>, old SunOS's require it for
3991 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
3993 A test port of gdb-3.92.6 to the Sony NEWS.
3996 Don't normally link in remote- or vx stuff.
3997 Some of it doesn't compile, and it wastes space for 99% of the users.
3998 Remove reference to no-longer-used HAVE_VPRINTF.
3999 Fixed BFD_DEP typo to BFD_DIR.
4001 Fix cast in arg to bfd_h_getlong.
4002 Make char *prefix be const.
4003 Fix how certain range types are mapped into builtin unsigned int types.
4005 Remove 2 #includes. They cause errors (on Sony, at least),
4006 and aren't needed (they wern't in earlier versions).
4008 print_address_symbolic should never demangle labels
4009 (since it prints *assembler-level* labels).
4011 [This was superseded by the change to printcmd below.]
4014 Add some "volatile" return types to avoid warnings.
4015 If MISSING_VPRINTF add vprintf function and not just macro
4016 (since vprintf is used in printcmd.c).
4018 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
4019 (The latter isn't grokked by some PCC-based compilers.)
4021 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
4023 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
4024 * nindy-share/coffstrip.c
4025 Added some forward declarations (otherwise, gcc complains
4026 about implicit extern redefined as static).
4028 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
4030 Changes inspired by Per Bothner:
4031 * printcmd.c (print_address_symbolic): Take additional parameter
4032 specifying whether to demangle.
4033 (print_address): Pass in asm_demangle to control demangling.
4034 (print_address_demangle): New fn, takes explicit arg to control
4036 * utils.c: Add new vars demangle and asm_demangle, and let them
4038 (fputs_demangled): If !demangle, just print the argument.
4039 (fprint_symbol): If !demangle, just print raw symbol.
4040 * valprint.c (val_print): Call print_address_demangle rather than
4041 print_address, to cause demangling to depend on the global
4042 rather than assembler-level demangling setting.
4043 * WHATS.NEW, gdb.texinfo: Document.
4045 * main.c (show_command): Show all settings if no arg.
4046 (initialize_main): Make "info set" the same as naked "show".
4047 * command.c (cmd_show_list): Handle prefix commands in the
4048 list, and print the name of the setting as well as its English
4049 description and value.
4051 Allow gdb functions to specify where a line should wrap if it
4052 exceeds the size of a terminal line. Use it to make the output
4054 * utils.c (set_screen_width_command): New fn, mallocs a buffer
4055 of the right size when screen width changes.
4056 (set_screensize_command, screensize_info): Remove #if 0'd fns.
4057 (wrap_here): New fn, indicates a point in the output where we
4058 should wrap the line rather than just letting it overflow at a
4060 (fputs_filtered): Implement wrapping.
4061 (n_spaces): New fn, returns a pointer to N spaces.
4062 (print_spaces_filtered): Use n_spaces.
4063 * defs.h (n_spaces): Declare.
4064 * stack.c (print_frame_info): Wrap with 4-space indent after
4065 fn name and before filename and line number.
4066 * printcmd.c (print_frame_args): Wrap with 4-space indent
4067 before each argument name is printed.
4068 * valprint.c (value_print): Wrap with no indentation before
4070 (val_print_fields): Wrap with indentation relative to nesting
4071 level before each field name.
4072 (val_print): Wrap with nesting indentation before array elements.
4073 * command.c (do_setshow_command): Avoid extra newlines,
4074 wrap with 4-space indent around values printed, end with period.
4075 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
4077 * breakpoint.c (breakpoint_1): Implement addressprint for
4078 "info breakpoints" display. Change file name and line number
4079 format to " at file:nnn" rather than " (file line nnn)".
4080 * gdb.texinfo: Document.
4083 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4085 Frozen for gdb-3.92.6 release.
4087 README, WHATS.NEW: Update for 3.92.6 release.
4089 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
4090 coffread.o from configs since it is now built by default.
4091 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
4092 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
4093 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
4094 from configs since it is now built by default.
4096 Makefile.dist: Update for release 3.92.6. Handle files that
4097 have been moved to ../include, ../getopt, or ../bfd. Add
4098 saber.suppress and tests directory. Add config.status to
4099 the release (it will say "none").
4101 coredep.c: Minor formatting fixes.
4103 These changes were made in early December but only checked in now:
4104 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
4105 nindy-share/nindy.c: lint
4106 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
4107 register values coming back from the target; we store values
4108 in target byte order everywhere.
4110 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
4112 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
4114 * valprint.c (cplus_val_print, val_print_fields): New functions,
4115 which print C++ objects. They conspire to avoid printing a
4116 virtual base class more than once, following all the twists and
4117 turns of C++ virtual base rules.
4118 (val_print): Call the above rather than do it by hand.
4120 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
4121 symbol file, not for added files like shared libs. This really
4122 needs to be generalized to a timestamp per file.
4124 * core.c (cleanup_core): Avoid coredump if no core file.
4126 * config.gdb: Accept -host or -target in place of +host or
4129 * coffread.c (find_linenos): Avoid desupported BFD interface
4130 to line numbers. We still read them manually rather than using
4131 BFD's "generic" features.
4133 * gdbrc.tex, threecol.tex: Add GDB reference card and its
4135 Makefile.dist: Add refcard to OTHERS list for creating tar files.
4137 * Makefile.dist: Eliminate use of $< in explicit targets.
4139 * readline/Makefile: Use $< rather than $*.c, which does not
4140 include the VPATH in GNU Make.
4142 * tconfig/i960-bout, tconfig/i960-coff: These are identical
4143 copies of tconfig/i960, added for global configuration
4144 compatability. All i960 versions can read both coff and b.out.
4146 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
4147 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
4150 * TODO: Think of more things to do.
4152 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
4154 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
4155 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
4156 64-bit float conversion.
4158 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
4159 equivalent to sun?os4 so global config works.
4161 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
4163 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
4165 * main.c: Only declare linesize once; declare pagesize not at
4166 all, since it is never used.
4167 (main): Clear newly allocated line before it is used.
4169 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
4171 Further stabilization for the Intel 960.
4173 * Makefile.dist: Parameterize the location of the "include"
4174 and "bfd" directories, as well as "getopt". Add symfile.c.
4175 Link in both dbxread and coffread. Fix up "make depend" to
4176 rewack the locations of include, bfd, and getopt in its output.
4178 * README: Document moving include files, improve some of
4181 * coffread.c: Move common code out to symfile.c. Change
4182 symbol_file_command style interface to use new *_symfile_init
4183 and *_symfile_read interface under BFD. Use BFD internal
4184 info to locate line table, symbols, etc.
4186 * core.c (core_fetch_registers): Rename to get_core_registers
4187 to avoid confusion with fetch_core_registers.
4188 (register_addr): Move to coredep.c, which is already machine
4189 dependent. This leaves core.c pretty clean of dependencies.
4191 * coredep.c (register_addr): Accept this routine from core.c.
4193 * dbxread.c: Move common code (with coffread.c, etc) into new
4194 symfile.c. Each psymtab now contains a pointer to the
4195 format-dependent function that knows how to read it in. Make
4197 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
4198 (process_one_symbol): Add code to complain about a "compiler bug
4199 we muzzle here", if we actually see it.
4201 * eval.c (evaluate_subexp): Insert missing "break" statements
4202 in code that determines whether a variable is an lvalue in
4203 memory, register, or whatever. I detected this via a compiler
4204 bug in which it *almost* mashed out the whole switch statement.
4206 * gdb-int.texinfo: Add minor sections on configuring gdb for
4207 release, and about the README file.
4209 * infcmd.c (registers_info): Fix formatting somewhat. Still
4210 not as pretty as before, but it handles byte swapping.
4212 * remote-nindy.c: If data cache routines are interrupted while
4213 waiting for the remote end, be sure that any uninitialized cache
4214 blocks are on the free list, not on the valid list!
4216 * symfile.h: Flesh out this header file with all the various
4217 routines and variables that have been merged in from dbxread.c
4218 coffread.c, and symtab.c to symfile.c.
4220 * symfile.c: New file, containing code common to dbxread.c,
4221 coffread.c, and some code from symtab.c. All generic code for
4222 reading symbol files should be in here now.
4223 (unrecord_misc_function): Remove unused function.
4225 * symtab.h: Remove file-reading things to symfile.h.
4227 * symtab.c: Remove file-reading things to symfile.c.
4229 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
4230 to decode i960 fault types.
4232 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
4233 target.c: Change type of the "resume" function from int to void,
4234 since its result was never used.
4236 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
4238 * main.c: Replace "stupid" with "caution"; you now "set caution
4241 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
4243 * infcmd.c (do_registers_info): Call val_print to deal with the
4244 byte order of the registers being printed. FIXME, this makes
4245 the formatting of the output uglier.
4247 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
4248 defined, call it for signals the debugger doesn't itself use.
4249 The i960 uses this for more detailed fault information.
4251 * remote.c (remote_open): If arg is null, print help rather than
4254 * sparc-xdep.c (register_valid): Avoid declaring size, since
4255 various modules will think of various sizes depending on the
4256 architecture of their tm-file. FIXME, we need protection against
4257 actually entering one of those modules, which would clobber
4258 storage if not for the target architecture compiled into gdb.
4260 * stack.c (up_command, down_command): Always print the frame
4262 (up_silently_command, down_silently_command): New commands
4265 * i960-pinsn.c (reg), i960-tdep.c: Lint.
4267 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
4268 more parameters than it used to.
4270 * findvar.c (registers): Increase slop to 256 bytes, which should
4271 protect us against even most RISC machines with large register
4273 (locate_var_value): Move declaration inside related ifdef.
4275 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
4276 throughout, to avoid throwing away buffered input from the board.
4277 (nindy_wait): Supply_register takes addr_of_value, not value.
4278 (i960_print_fault): Renamed from i80960_fault.
4279 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
4280 (nindy_store_registers): Avoid regs_changed stuff, just stuff
4282 (nindy_create_inferior): Don't bother to write PC_REGNUM since
4283 we can set the PC in the call to proceed(). Unpush nindy_ops
4284 before pushing it on top, to avoid message to user. Eliminate
4285 commentary from Unix machines that just misleads here.
4286 (reset_command): Fix error message to suggest target command.
4288 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
4290 Release 3.92.5 as frozen.
4292 Stabilize the merged release...with help from lint, Saber C,
4295 Everywhere: Add include files needed to declare return types
4296 of functions called.
4298 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
4300 * breakpoint.h: Add undeclared breakpoint functions, and some
4301 functions for display handling since I couldn't think of a better
4304 * breakpoint.c (insert_breakpoints): Make code for disabling
4305 shared library bkpts more likely to work. It's used when we
4306 rerun a program and stop before the shared library has been
4308 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
4309 cast from pointer, so it squeezes through catch_errors.
4310 (bpstat_stop_status): Fix logic broken some time ago. We now
4311 always create a bpstat if the stop address matches a breakpoint,
4312 even if we don't stop there -- just like the old code used to do
4313 before I got my fingers into it (sigh).
4314 (breakpoint_1): Print "ignore count" after "stop only if"
4315 condition, since that's how it actually works.
4316 (mention): Handle watchpoints as well as breakpoints.
4317 (watch_command): use set_raw_breakpoint and mention to do most
4318 of the work (and initialize all the fields!). Only pass one
4319 arg to parse_c_expression, since that's all it takes.
4321 * command.c (not_just_help_class_command): Rename arg to args
4322 since we ignore "unused argument" warnings on vars named "args".
4323 inflow.c (child_terminal_info): ditto.
4324 infptrace.c (kill_inferior): ditto
4325 main.c (catch_errors, version_info, quit_command, pwd_command,
4326 source_command, dump_me_command, editing_info,
4327 set_history_size_command, set_history, show_history,
4329 stack.c (locals_info): ditto
4330 target.c (target_files_info): ditto
4331 valprint.c (set_input_radix, set_output_radix): ditto
4333 * core.c: Remove old variables for handling core and exec file
4334 sections (data_start, data_end, stack_start, stack_end,
4335 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
4336 text_end, exec_data_start, exec_data_end, text_offset,
4337 exec_data_offset, data_offset, stack_offset). They're
4338 superseded the more general build_section_table and
4340 (get_exec_file): Mention the `file' command.
4341 (read_memory_check): Rename to memory_error, and only call it
4342 in the case of an actual error.
4343 (read_memory, write_memory): call memory_error.
4344 (core_fetch_registers): Register section name is ".reg".
4346 coredep.c: Remove a bunch of crud now that all this file does
4347 is pull the registers out of a core file.
4348 (fetch_core_registers): Rewrite to actually work, I hope.
4350 dbxread.c: Use a.out.gnu.h, not system a.out, now.
4351 Replace index() with strchr(). Remove all the pre-BFD macro
4352 definitions for accessing the symbol file.
4353 (struct dbx_symfile_info): Encapsulate the information that
4354 dbx_symfile_init needs to pass to dbx_symfile_read in this
4357 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
4358 dbx_symfile_discard): Rearrange symbol file reading to divide
4359 the format-specific part from the format-independent part,
4360 leaving the format-independent part such as file name expansion
4361 and opening in symtab.c. This replaces
4362 partial_symbol_file_open and partial_symbol_file_read.
4363 Symbol_file_read, add_file, add_file_target_command,
4364 add_file_addr_command move to symtab.c. Pass an explicit
4365 "mainline" flag for when reading the main symbol table, rather
4366 than relying on the offset address to be zero or nonzero.
4368 (dbx_symfile_read): Don't allow void *'s to be printed as
4370 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
4371 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
4372 macro" debug version really work.
4373 (read_dbx_symtab): Remove unref'd parameter inclink.
4374 Avoid swapping N_SLINE symbols, for speed.
4375 Merge N_TEXT!N_EXT case with the other external symbol
4376 definitions' case. Add comments.
4377 (start_psymtab): Allocate the symfile name in the psymtab on
4378 the psymbol_obstack, rather than using the caller's storage.
4379 (end_psymtab): Only allocate a dependencies list if there are
4381 (psymtab_to_symtab_2): Use BFD when reopening file to read
4382 its symbols for real.
4383 (read_struct_type): Add FIXME comments where it needs work
4385 (read_huge_number): Add FIXME about overflows.
4386 (read_range_type): Add FIXME about comparing a long to 1<<32.
4388 * coffread.c: Minor changes to move things closer to the new
4389 regime with symtab.c and dbxread.c Major work is still needed
4392 * exec.c (exec_file_command): Remove old variables (see core.c
4394 (xfer_memory): If memory transfer is right at the end of a
4395 section, don't lose.
4397 * findvar.c (get_saved_register): If value is in a real
4398 register, LVAL is lval_register, not lval_memory.
4400 frame.h: Declare print_sel_frame and record_selected_frame.
4402 gdb-int.texinfo: New file, for GDB internals documentation.
4403 Very simple, unformatted doc of cleanups is there for now.
4405 gdbcore.h: Remove obsolete variables that described a.out
4406 section addresses and offsets. (See core.c above.)
4407 Declare fetch_core_registers and registers_fetched.
4409 getopt.c: Declare char *alloca(); even on SPARC.
4411 infcmd.c (run_command): Call target_kill rather than
4413 (step_command, next_command, stepi_command, nexti_command):
4414 Declare from_tty parameter even though we don't use it.
4415 (run_stack_dummy): argument BUFFER is a char array, not
4416 a pointer to REGISTER_TYPE.
4417 (finish_command): using_struct_return needed a value *,
4418 not a struct symbol *.
4420 * infptrace.c (child_xfer_memory): To avoid dependency on
4421 where sections are in memory, try PT_WRITE_D and if that fails,
4422 try PT_WRITE_I. Most Unixes don't care which you use.
4424 * infrun.c (step_resume_break_shadow): Change to array to
4425 match other breakpoint shadow storage.
4426 (clear_proceed_status): Pass address of bpstat to
4427 bpstat_clear, not the bpstat itself.
4428 (child_create_inferior): FIXME comment about if the child
4430 (start_inferior): Remove old function.
4431 (child_open): Use target_kill rather than kill_inferior.
4432 (wait_for_inferior): Ditto.
4433 (insert_step_breakpoint, remote_step_breakpoint): Use
4434 new step_resume_break_shadow.
4436 * inftarg.c (child_wait): If all child processes die,
4437 pretend that the one being waited for exited with signal 42.
4439 * main.c (command_line_input): When scanning for comments,
4440 don't coredump on unclosed quotes.
4441 (quit_command): Use target_kill rther than kill_inferior.
4442 (_initialize_main): Rename class_user from "user" to
4445 * printcmd.c (print_command_1): Initialize "fmt" if no format
4446 is specified by the user.
4447 (print_frame_args): Only add to args_printed if we are
4448 actually fetching args from the stack (avoiding undefined
4450 (_initialize_printcmd): Remove bogus \{ from string.
4452 * remote-eb.c (eb_open): Avoid coredump on no argument.
4454 * remote-nindy.c: Bring out of Intel environment into new
4455 target environment. Remove all conditional compilation on
4456 I80960. Massive hacking throughout.
4457 (nindy_xfer_inferior_memory): New routine stolen from
4459 (nindy_create_inferior): New routine pieced together, probably
4460 not quite working yet.
4461 (nindy_ops): New target_ops struct for nindy.
4463 * remote-vx.c: Use write_memory rather than target_write_memory
4464 to get error checking.
4465 (vx_add_file_command, vx_open): Use symbol_file_add rather than
4467 (vx_create_inferior): Use target_terminal_ours...
4469 * signame.c (_initialize_signame): Always initialize, since
4470 we need the table for things other than psignal.
4472 * solib.c (solib_add): Use symbol_file_add, not add_file.
4473 (solib_address): Return boolean result rather than struct
4474 pointer which nobody else knows the type of.
4476 * sparc-tdep.c, valops.c: Use write_memory rather than
4477 target_write_memory, to get error checking.
4479 * stack.c (locals_info, catch_info, args_info,
4480 get_selected_block, frame_command, up_command): Use
4481 target_has_stack, rather than have_inferior_p or
4484 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
4486 * symfile.h: New file, defining the interface between the
4487 generic and object-file-specific symbol reading code.
4489 * symtab.c: Move generic symbol-reading interface to symtab.c,
4490 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
4491 table to map BFD targets to symbol-reading modules in GDB.
4492 Change index to strchr.
4493 (lookup_struct_elt_type): Use error() rather than hand-made
4494 simulations thereof.
4495 (lookup_partial_symbol): Speedup slightly when length == 0.
4496 (symbol_file_add): New function.
4497 (symbol_file_command): Call it.
4498 (symfile_open, symfile_init): New function.
4499 (add_file_target_command, add_file_addr_command): moved from
4502 * target.c (target_command): use target_kill.
4504 * target.h (target_files_info): Don't declare, never called
4507 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
4508 files to determine stack end address.
4510 * valarith.c (value_x_binop, value_x_unop): Change error message
4511 to be more useful. Pass proper argument to value_struct_elt.
4513 * valops.c (value_assign): FIXME comment that long long
4514 bitfields will break here.
4516 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
4517 Update `make saber_gdb' to work better.
4519 * TODO: A woman's work is never done.
4521 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
4522 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
4523 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
4524 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
4525 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
4526 valops.c, valprint.c, exec.c: Lint.
4529 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
4531 Continuing Intel 960 port merge of GDB.
4533 * Makefile.dist: Merge i960 "nindy-share" files. Rename
4534 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
4535 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
4536 Wack over "make depend" so it handles files in subdirectories
4537 vx-share, nindy-share, bfd, and in the current directory.
4539 * blockframe.c (get_prev_frame_info): Remove fatal error
4540 if stack not defined.
4542 * core.c (core_open, core_detach): New functions that handle
4543 the old "core-file" command as "target core" and "detach" instead.
4544 (core_file_command): Call them.
4545 (core_xfer_memory): Use common routine xfer_memory.
4547 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
4548 dbxread now uses bfd for everything but symbol reading itself.
4549 BFD internals are used to drag out the relevant file offsets.
4550 (partial_symbol_file_open): Change args all around for BFD.
4552 * symtab.c: Rename "value" to "val" everywhere, so we can
4554 (symbol_file_command): New command, moved from dbxread.c
4555 and coffread.c. It uses BFD to read the file, then vectors
4556 based on its type, to dbx or coff symbol readers.
4557 * symtab.h: Extern a few vars for symbol_file_command.
4559 * target.h: Breakpoint takes a char * save area, not a char **.
4561 * valprint.c (val_print): When unpacking bitfields, offset
4562 the address in gdb of the value, if it is declared with a shorter
4563 type. Remove the last "runtime kludge test" of host byte order.
4565 * utils.c: Remove old my_bfd_read routine.
4567 * stack.c (frame_info): Use target_has_stack. Print program counter
4568 register's actual name rather than "pc", since it's called the
4569 "ip" (instruction pointer) on the i960 (sigh).
4571 * target.c (target_command): Add command for selecting a target
4572 type and calling its open routine. This is used for initiating
4573 communication with a particular target, in a generic way.
4575 * tm-i960.h: Update for modern gdb. Remove semicolons from
4576 various macros. Handle reading struct return convention, and
4577 error-out attempts to return structs with the "return" command.
4578 Be sure gdb doesn't think we know how to call functions in the
4581 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
4582 to i960_xxx in lower case.
4583 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
4584 not being defined yet.
4586 * remote.c (remote_open): Call start_remote to initialize
4587 wait_for_inferior during open.
4588 (remote_xfer_inferior_memory): Return length written rather
4591 * remote-vx.c (target_command -> vx_open): Use new generic
4593 * remote-eb.c, inftarg.c, exec.c: ditto.
4595 * infrun.c: Fix comments.
4596 (attach_program -> child_open): Use new generic target command.
4597 (wait_for_inferior): Clear saved register values before target_wait,
4598 so target_wait can set some of them if convenient.
4600 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
4601 Return success indicator, not void.
4602 (child_xfer_memory): Avoid fetching initial word if we'll
4603 overwrite it anyway.
4605 * infcmd.c (attach_command): Use new generic target open routine.
4606 (_initialize_infcmd): Update doc on attach and detach commands.
4607 (do_registers_info): Merge in a byte-order problem as a FIXME
4610 * findvar.c (find_saved_register): Avoid problem in current frame.
4611 (read_relative_register): Ditto.
4612 (write_register): Convert byte order on the way out.
4614 * exec.c (file_command): Add.
4615 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
4616 (xfer_memory): Common function between core_xfer_memory and
4618 (exec_xfer_memory): Use it.
4620 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
4622 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
4623 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
4624 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
4626 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
4628 Merge Intel 960 port of gdb, continuing...
4630 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
4631 symbol_file_command): Pass from_tty arg to hush 'em up.
4633 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
4634 Add magic numbers for 960 COFF format.
4636 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
4638 Merge Intel 960 port of gdb, from Intel "1.2" release.
4640 CHANGE_LOG entries from their port, which was based on
4643 Thu Sep 6 11:02:22 PDT 1990
4644 Remove temp file if download is interrupted.
4646 Wed Aug 1 09:08:33 PDT 1990
4647 Now uses binary protocol to talk to NINDY.
4648 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
4649 Times out after 5 seconds when trying to talk to NINDY.
4651 Tue May 29 12:54:49 PDT 1990
4652 Added variable baud rate (-b switch).
4653 Source code reorganization.
4655 Thu Apr 26 11:09:55 PDT 1990
4656 More cleanup of batch mode; specifically, execute "-s", "-e", and
4657 "-se" switches as soon as they are encountered on the invocation line.
4659 Fri Apr 20 13:47:15 PDT 1990
4662 Thu Apr 19 09:54:28 PDT 1990
4663 Add 'reset' command.
4665 Wed Apr 18 09:48:07 PDT 1990
4666 After opening remote tty, wait for 1 second to go by without input
4667 from it before trying to talk to NINDY (fixes problems with the
4668 Heurikon HK80/V960E).
4670 Mon Apr 4 16:33:05 PDT 1990
4671 Some output was not being suppressed in 'batch' mode.
4673 Thu Mar 22 15:31:11 PST 1990
4674 Ask user if old symbol table should be deleted when new file is
4677 Allow user to run a program downloaded before gdb960 was brought up.
4679 Correct "exec-file" help message for i80960 context.
4681 Correct bug in calculating user space address: could occasionally
4682 corrupt user program.
4684 Make sure to zero low-order bits in rip's because of bug in 960CA
4685 A-step part: could cause operation faults when "next"ing across
4688 Correct bug that made it impossible to get source line numbers for
4689 code loaded at addresses higher than 0x7fffffff.
4691 Wed Jan 10 12:43:22 PST 1990
4692 Open remote tty for exclusive use.
4694 Fri Jan 5 12:14:42 PST 1990
4695 Correct disassembly (CA manual was right after all):
4696 opcode for sysctl is 0x659
4698 Mon Oct 23 12:03:04 PDT 1989
4699 Use G960BASE and G960BIN environment variables to find 'sx' utility.
4701 Mon Oct 16 14:15:09 PDT 1989
4702 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
4704 Mon Oct 2 15:56:31 PDT 1989
4706 Added 960CA disassembly support.
4708 To simplify maintenance:
4709 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
4711 - eliminated opcode.h: incorporates tables into i960-pinsn.c
4712 - moved 960-specific routines from i960-pinsn.c to i960-md.c
4713 - made disassembly interface identical to that in gdmp960.
4717 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
4719 * target.h: Allow targets to stack. Add target_has_memory,
4720 _registers, etc. Restructure memory access and "info files"
4721 to walk the target stack.
4722 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
4723 target.c: Change tables to match target.h.
4724 * inflow.c (child_mourn_inferior): pop child_ops.
4725 (generic_mourn_inferior): Use new has_stack flag.
4726 * infptrace.c (child_xfer_memory): New memory regime.
4727 * inftarg.c (child_files_info): New "info files" regime.
4728 * remote-eb.c: New memory regime, new info files.
4729 * remote-vx.c: New memory regime, new info files. Now use
4730 separate targets for VxWorks attachment to machine, and
4731 actually running a process under VxWorks, since one has
4732 stack & execution & regs and the other doesn't.
4733 * remote.c: New memory regime, new info files.
4734 * sparc-xdep.c (fetch_core-registers): New memory regime.
4735 * target.c: New routines and support for stacked targets,
4736 new memory regime, new info files regime.
4739 Generalize section handling for an arbitrary number of sections,
4740 including use of the new BFD (binary file) library.
4741 * gdbcore.h: Add struct section_table.
4742 * exec.c (build_section_table): Iterate all sections and
4743 record what gdb needs to know about them.
4744 (exec_command): Use it.
4745 (exec_xfer_memory): Use the table.

4750 * dbxread.c: Quick changes to make it compile with new BFD.
4751 * utils.c (error): Avoid using bfd_error in generic routines.
4753 * core.c (core_fetch_registers): Get from the ".regs" section of
4755 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
4757 * inferior.h (attach_flag): Export.
4758 * infcmd.c (run_command): use new target_create_inferior.
4759 * infrun.c (child_create_inferior): Don't return result.
4760 * Makefile.dist (VERSION): 3.91.4.
4762 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
4764 * breakpoint.c (bpstat_num): Handle breakpoints which have
4765 since been deleted, such as temporary breakpoints.
4766 infcmd.c (program_info): ditto.
4768 * core.c (core_file_command): Display the frame where the core
4773 * remote-vx.c (target_command): Merge in target command from
4774 targ-vx.c. A few other cleanups.
4776 * TODO, Projects: Lots more stuff to do...
4778 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
4780 Massive changes to wall off the remote-debugging interface
4781 behind a function vector. The port to handle VxWorks targets
4782 is also part of this.
4784 All files: Replace references to renamed functions,
4785 remove references to remote_debugging, remove references to
4786 have_include_file, have_core_file in favor of target_has_stack,
4787 target_has_memory, etc.
4789 * Modularize the breakpoint interface.
4790 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
4791 a breakpoint instruction.
4792 breakpoint.c: struct breakpoint's shadow_contents now sized as
4794 (insert_breakpoints): Vector to target to install breakpoints.
4795 (remove_breakpoints): Vector to target here too.
4796 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
4797 sparc-tdep.c (single_step): Use new breakpoint interface for
4798 the single-step breakpoints.
4799 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
4800 New file, contains routines to insert and remove breakpoints by
4801 reading out the old contents and later replacing them. This is
4802 how ptrace breakpoints work, and many remote systems as well.
4804 * tm-vxworks68.h: New config file, overrides a few things for
4805 Wind River's preferences.
4807 * target.h: New file, for transfer vector used to talk to the
4808 inferior (child, attached, core, exec, remote, etc). All accesses
4809 to the thing being debugged should come through these vectors.
4810 target.c: New file, routines to handle transfer vector.
4811 (various files): Add transfer vectors XXX_ops for the various
4812 targets and pseudo-targets (core files, etc) we support.
4814 * breakpoint.c (bpstat_stop_status): Further explorations of
4815 watchpoints and why things don't work all the time.
4816 (bpstat_alloc): New fn to allocate a bpstat and chain it.
4818 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
4819 the local gdbinit if it doesn't already have it.
4821 * core.c (core_ops): add and install.
4822 Allow core debugging without exec file.
4824 * dbxread.c (free_and_init_header_files): Merge two fns.
4825 (end_symtab): Free named symbol table when a new version comes in.
4826 (read_dbx_symtab): Relocate all kinds of symbols with base
4827 address. First step toward handling different text, data, bss
4829 (add_file_addr_command): Renamed add_file_command.
4830 (add_file_command): Vector to remote handler.
4831 Add "load" as an alias for "add-file" command.
4833 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
4834 non-returning functions.
4836 * exec.c: Add exec_ops, and push it as a target when an exec
4839 * infcmd.c (run_command): Pass executable file name and arg list
4840 separately when starting an inferior. Permit "run" when no exec
4841 file is specified, for VxWorks.
4842 (detach_command): Move to child_detach in inftarg.c.
4844 * inftarg.c: New file. Unix-child-specific routines, and the
4845 child_ops structure.
4847 * inferior.h (registers): Export "registers" as the way for
4848 target dependent register handlers to find gdb's local copy of
4849 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
4850 since it is now used by places that want wait_for_inferior to
4851 handle the grunge but want to see every trap from the inferior.
4853 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
4854 Eliminate remote_debugging hooks in terminal handling.
4856 * infrun.c: Replace start_inferior with child_create_inferior.
4857 Move all the hair of Unix shells and ptrace idiosyncracies into
4858 child_create_inferior, so remote handlers don't have to deal.
4859 Remove running_in_shell. Rename stop_after_attach to
4860 stop_soon_quietly, and use it in a few other places where we want
4861 to just call wait_for_inferior and get control back on the first
4862 trap. trap_expected now never takes a value > 1.
4863 (init_wait_for_inferior): Initialize static vars when a new
4866 main.c (gdbinit): Add new hook for .gdbinit file name, let
4867 it be overridden by config files as GDBINIT_FILENAME.
4868 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
4869 Both of these are used for VxWorks gdb.
4871 mcheck.c: rename include file "gmalloc.c" to avoid problems
4872 with system include file "malloc.c".
4874 param-no-tm.h: New include file, same as param.h but does not
4875 include the default "tm.h" file. This is used in files where
4876 the target is known, e.g. remote-eb.c or sparc-xdep.c.
4878 param.h: Now just a shell that includes tm.h and param-no-tm.h.
4880 remote-vx.c: New file, VxWorks remote debugging support. Uses
4881 RPC routines that are shared with the target system, in directory
4884 remote.c: Vectorize remote interface.
4886 source.c: Globalize source_path, and make an alias "l" for "list"
4887 since we now have the "load" command.
4889 sparc-xdep.c: Use new param-no-tm.h.
4891 symmisc.c (free_named_symtab): Add new function from Wind River.
4892 However, ifdef it out for now while we think about what it should
4895 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
4897 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
4898 non-Unix-children handle this with their own code in the target
4901 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
4902 source and target lists. Add vx-share to default list of include
4903 directories. Add new files to src and target lists: mem-break,
4904 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
4905 ${srcdir} versions of munch and createtags are used.
4907 * valops.c (find_function_addr): Split out of call_function.
4908 (call_function_by_hand): Rename call_function; this function
4909 calls functions in the target by laboriously patching the target
4910 word-by-word with the right stack, args, regs, etc.
4913 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
4915 Handle AMD 29000 a bit better.
4917 * remote-eb.c (readchar): Mask received char log to make it readable.
4918 (remote_start): Pass arguments down to executing program.
4919 Make startaddr unsigned.
4920 infrun.c (start_inferior): Accept args, pass them to
4922 infcmd.c (run_command): Pass args down to start_inferior.
4924 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
4925 the target object file format.
4926 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
4928 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
4929 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
4931 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
4933 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
4934 * TODO: We did a few things, we have more to do though.

4939 * Debug problems with dummy frames and calls to the inferior.
4940 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
4941 * sparc-tdep.c (do_restore_insn): Simplify.
4942 (sparc_frame_find_saved_regs): Simplify and fix what we find.
4943 (sparc_push_dummy_frame): Simplify and fix what we push.
4944 (sparc_pop_frame): Slightly more hair here, deciding whether
4945 we are restoring a saved PC or returning to a return address in %i7.
4946 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
4948 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.

4950 * obstack.h (chunkfun): ditto.
4951 * defs.h (xmalloc, xrealloc): ditto
4953 * utils.c (quit): Grab the terminal from the child if necessary.
4955 * inflow.c (term_status_command): Rename to term_info, change
4958 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
4959 (is_delayed_branch): Speed up.
4960 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
4961 Still missing some float ops, and needs testing.
4963 * Support for input and output radixes other than base 10
4964 * defs.h (input_radix, output_radix): Declare.
4965 * expread.y (yyparse, parse_number): Handle changes of input
4966 radix, and ambiguous names-or-numbers in radixes >10.
4967 * printcmd.c (print_scalar_formatted): Print formatted hex
4968 numbers in varying column widths.
4969 * valprint.c (val_print): Use output_format to print scalar ints.
4970 (set_input_radix, set_output_radix, set_radix): Create.
4971 (set_output_radix): Set output_format from output_radix.
4972 (_initialize_valprint): add `set radix' but leave the others off.
4974 * main.c (execute_command): Let stupid questions be turned off.
4975 (_initialize_main): Handle "set stupidity", etc.
4977 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
4978 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
4980 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
4982 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
4983 bfd stuff is still screwed up, but with some manual work, it
4986 * breakpoint.c (bpstat_do_actions): Start over if a command
4987 proceeds the inferior, since the inferior will have stopped and
4988 will need to have its new stop-actions taken care of.
4990 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
4991 compiler fits, simplify it.
4993 * gdb.texinfo (directory command): Doc new dir command.
4994 source.c (directory_command): "dir" now puts things on the front
4995 of the path, moves dups up front, and handles multiple names
4996 on the command line, inserting each one in order. It also
4997 blows away cached line and full_filename info.
4999 * stack.c (backtrace_command): Skip "more stack frames follow"
5002 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
5003 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
5004 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
5005 The only odd one was Gould NP1, which had defined vprintf to
5008 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
5009 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
5010 variable, inspect_it.
5011 valprint.c (print_string, val_print): Use the global inspect_it
5012 to indicate whether to print in Epoch style or normal style.
5014 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
5016 * printcmd.c (call_command): add an alias for the "print" command
5017 which runs expressions and doesn't print the result if void.
5018 (print_command_1): implement it.
5020 * command.c: Remove #if 0'd code. Initialize all the fields
5021 in add_cmd (). Rename do_nothing_command to
5022 not_just_help_class_command, and make it externally visible.
5023 command.h: add user_commands to struct.
5024 * main.c (define_command): Don't overload c->function with a char
5025 string as well as a function pointer.
5027 * eval.c (evaluate_subexp): Reinstall tiemann changes to
5028 calling convention of value_struct_elt () that got dropped in
5031 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
5032 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
5034 * tm-sparc.h (POP_FRAME): replace some constants with defines.
5036 * sparc-xdep.c (store_inferior_registers): defer stores to regs
5037 until a good time (e.g. when we are about to run the child),
5038 saving ptrace calls.
5039 * infrun.c (proceed): handle DO_DEFERRED_STORES.
5040 * tm-sparc.h: define DO_DEFERRED_STORES.
5042 * sparc-xdep.c (store_inferior_registers): when storing float
5043 registers, don't store stack regs too. When storing the SP,
5044 however, DO store the stack regs too. This fixes a bug in which
5045 the dummy frame is not recognized when a call_function finishes,
5046 because its frame pointer (in the stack regs) was never
5048 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
5049 even though we don't know how to read them from an inferior.
5050 valops.c (call_function): Comment about storing SP.
5052 * infrun.c (save_inferior_status): Save away the original bpstat
5053 chain so it can be restored later. Install the copied version for
5054 use by whoever saved the status. It will be blow away by
5055 restore_inferior_status, and the original chain restored. This is
5056 important for people who have pointers into the original.
5058 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
5059 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
5060 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
5063 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
5065 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
5066 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
5067 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
5069 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
5071 * Merge Mike Tiemann's multiple inheritance changes from Sun.
5072 Store the baseclasses in a type struct starting from array element
5073 0 rather than from the unusual array element 1.
5075 dbxread.c: the above.
5076 (virtual_context): Add
5077 Read new debug information about which virtual function table
5078 a virtual function is from, and store it in fn_field.fcontext.
5080 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
5081 TYPE_FN_FIELD_STATIC_P.
5083 symtab.c: the above.
5084 valops.c: the above. Handle pointer casts of object *'s.
5085 (search_struct_method): Add.
5086 (value_struct_elt): First arg is now a pointer to a value, and is
5089 valprint.c: the above.
5090 values.c (value_virtual_fn_field): Add type arg. Handle
5091 offsetting to the proper object when calling virtual fns.
5093 (baseclass_addr): Add valuep arg.
5095 * README: Document the current state of BFD config (missing).
5096 * TODO, ChangeLog, Makefile.dist: Roll version.
5097 * WHATS.NEW: Add summary of changes since 3.5.
5099 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
5101 * dbxread.c (read_struct_type): Clear bit vectors whenever
5103 symtab.c (B_CLRALL): define.
5105 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
5106 using == rather than =. Huh... This fixes the dreaded problem
5107 wherein builtin_type_int becomes TYPE_CODE_FLT.
5109 * core.c (info_files): Show the inferior pid.
5111 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
5112 already knows how to look in the source directory.
5114 * Remove psymtab hair from many places. Remove duplicated code
5115 for searching symbol tables. Hide psymtabs from most places.
5116 Make it fast to get from a psymtab to its symtab.
5118 blockframe.c (blockvector_for_pc): Remove psymtab hair.
5119 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5120 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5121 dbxread.c: export psymtab_to_symtab, make it work if called N times.
5122 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
5123 new symtab completely. New psymtabs get symtab pointer
5124 initialized to zero. Remove MI warning printf.
5125 symtab.h: Comments. Add psymtab to symtab pointer.
5126 (PSYMTAB_TO_SYMTAB): New macro.
5127 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
5128 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
5130 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
5132 (print_frame_info): Avoid special-casing symbols that have not yet
5135 * source.c (open_source_file): Quick path if we have already
5136 located the source file by its full name.
5138 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
5139 find_pc_psymtab. When a name is found in the misc function
5140 vector, search the symbol table for its mangled name, not the
5141 name that the user typed.
5143 * bfd.h: Fix missing comment terminators, make #endifs match.
5145 * valarith.c (value_less): Handle unsigned int comparisons.
5146 Add FIXME about pointer compares, which assume host and target
5147 pointers are the same.
5149 * command.c (do_nothing_command): lint
5150 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
5151 fix comments on debug symbol format for visibility. Actually set
5152 visibility of symbols.
5153 main.c (echo_command): lint; use <readline/history.h>.
5154 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
5155 obstack.h (_obstack_blank): Rearrange pointer math to avoid
5156 pointing past end of allocated memory; saber complains.
5157 obstack.h: Declare the external functions that we use.
5158 valarith.h: use <string.h>
5159 solib.c (solib_add): lint.
5161 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
5163 * main.c (initialize_main): Default info_verbose to off, now that
5164 symbol reading is fast.
5165 (quit_command): Avoid clobbering exec_bfd while quitting.
5167 * Initial BFD (binary file diddling library) merger:
5168 coffread.c: Change AOUTHDR to struct exe_hdr.
5170 core.c: initialize initialized data at compile time.
5171 (core_file_command): Move from coredep.c, convert to bfd.
5172 (xfer_core_file): Convert to bfd.
5173 exec.c (exec_file_command): use bfd routines.
5175 mips-tdep.c: Remove exec_file_command and friends.
5178 * coredep.c: (fetch_core_registers) Convert core_file_command to
5179 fetch_core_registers.
5180 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
5182 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
5183 (my_bfd_read): More bogosity, which I don't think we call.
5184 (program_name): Remove this atrocity asap!
5186 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
5189 values.c: allocate_repeat_value was not clearing the
5190 optimized_out field.
5191 (value_static_field): minor stylistic fix (wrong macro was used).
5192 valops.c (value_struct_elt_for_address): didn't work for C++
5195 * signame.c (_initialize_signame): Initialize signal names once.
5197 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
5198 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
5199 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
5201 * remote-eb.c: Support user-settable baud rates on the serial port.
5203 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
5205 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
5207 * tconfig/sun3os4: Remove warning about native assembler,
5208 since it also occurs in the xconfig file.
5210 * findvar.c (registers): Allocate some slop after `registers'
5211 to prevent stray accesses from trashing the next variable.
5213 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
5214 on the sun-3, by changing the #ifdef from `sun3' (which is not
5215 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
5216 vars, which happened to follow `registers' in the executable.
5218 * readline/history.c (history_search): Heed gcc-2's advice
5219 and parenthesize && inside ||).
5221 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
5222 tm-29k.c: Insert FSF copyright headers.
5224 * remote-eb.c: Better comments.
5226 * Makefile.dist: Update to 3.91.6.
5227 * TODO: note PREPARE_TO_STORE problem.
5229 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
5231 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
5233 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
5235 * infrun.c (wait_for_inferior, at end): Don't set up
5236 prev_* if the inferior no longer exists.
5238 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
5239 CANNOT_EXECUTE_STACK.
5240 valops.c (call_function): Use it.
5242 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
5244 * inferior.h (PC_IN_CALL_DUMMY): New macro.
5245 infrun.c (wait_for_inferior, 2 places): Use it.
5247 * values.c (value_being_returned): Only use
5248 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
5250 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
5251 right thing for remote-eb.c.
5253 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
5254 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
5256 * blockframe.c: Put get_frame_saved_regs inside #if !defined
5257 (FRAME_FIND_SAVED_REGS).
5259 * findvar.c ({fetch,store}_registers): Check for
5260 REMOTE_{FETCH_STORE}_REGISTER macro.
5262 * findvar.c (get_saved_register): Add argument lval and
5263 change meaning of argument addr.
5264 findvar.c: Change calls to get_saved_register to reflect
5265 new calling convention.
5266 valops.c (value_assign): Use get_saved_register instead of
5267 find_saved_register.
5269 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5271 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
5272 an (uninitialized) pointer to one. Use "&" when passing it
5275 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5277 * coffread.c (getfilename): Use DGUX x_offset and x_name if
5280 * coffread.c (symbol_file_command): Put semicolon after
5282 Put safe_to_init_tdesc_context in #if defined (TDESC).
5283 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
5284 coffread.c: #include <sys/stat.h>.
5285 (read_coff_symtab): Typo: in_source_files -> in_source_file.
5286 Add missing ')' in check for "lc%" and friends. Remove
5288 Declare read_one_sym() at top of file.
5289 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
5290 MC68WRMAGIC can have the same value without causing a duplicate
5293 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
5295 * Allow a Makefile to be built without building the
5296 tm and xm file links that screw up builds in subdirectories.
5297 This is done with `config.gdb none', then you can do things
5298 like `make gdb.tar.Z'.
5299 * tconfig/none: Config file for no target system
5300 * xconfig/none: Config file for no host system
5301 * config.gdb: If no TM or XM files are called out by the
5302 host or target file, don't make links for them.
5304 * cplus-dem.c: Add documentation.
5306 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
5307 simple error, so the user's gdb doesn't crash due to some object
5308 file problem (e.g. somebody is rebuilding the file out from under
5311 * printcmd.c (print_address_symbolic): demangle the symbol.
5313 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
5314 Motorola copyrights in it. Make "make gdb.tar.Z" work.
5315 (alldeps.mak): sort and uniq all results from this; duplicates
5316 hose gdb.tar.Z link building. Remove RCS files from
5317 tconfig and xconfig. Add config files for sun386. Add
5318 a few odd files to OTHERS and HFILES.
5320 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
5322 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
5323 Roll version number to 3.91.5. Make lint work in bindir.
5325 * README: Document cross-debugging and new file structure.
5327 * blockframe.c: Lint. Include "value.h" to declare read_register.
5328 (find_pc_partial_function): remove duplicate line.
5330 * command.h: Lint. Declare error_no_arg and dont_repeat.
5332 * tm-news.h: Remove inadvertently duplicated stuff.
5334 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
5335 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
5337 * config.gdb: Allow `config.gdb host target' form. Clean
5338 up previous change that printed bogus messages when you just said
5341 * core.c: #include "command.h" for lint.
5344 * main.c: Remove some casts of enums. Lint.
5351 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
5353 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
5354 read it from memory. This will allow us to save ptrace calls
5355 eventually. Changed caller single_step too.
5357 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
5358 that we aren't going to use, saving many ptrace calls, especially
5359 when watchpointing or single stepping. Use some #define's for
5361 (store_inferior_registers): Ditto.
5362 (core_file_command): Use some #define's for constants.
5364 * tm-sparc.h: Add #define's for some register numbers, so we
5365 can eliminate the use of random constants in sparc-xdep.c.
5367 * stack.c (frame_command, print_frame_info, up_command,
5368 down_command) Remove frame_changed, since it
5369 causes a bug and doesn't seem to do anything useful. In some
5370 places it was used as a flag, in others as a stack level (?).
5372 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
5373 default is to use the portable (vprintf) version rather than the
5375 * xm-news.h (MISSING_VPRINTF): Add.
5377 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
5379 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
5381 * Remove stuff that forces -Bstatic linking of gdb, and warnings
5382 about linking debugged programs -Bstatic in the sun?os4 config
5383 files in tconfig and xconfig subdirectories.
5385 * main.c (main): Remove unreached exit(0) now that we exit
5388 * Create TODO file for online bug list. There are too many
5389 "little" bugs to keep track of on paper.
5391 * Change Projects file to refer to bug-gdb@cygnus.com
5392 rather than kingdon@ai.
5394 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
5396 * Makefile.dist (VERSION): 3.91.4 now.
5398 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
5399 (condense_misc_bunches): Add sanity check that misc_count is
5400 the same as the number of symbols in the bunch.
5402 * coffread.c: rename init_misc_bunches. Pass an argument
5403 to condense_misc_bunches (a zero).
5405 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
5406 every time we are called; don't rely on our caller to do it.
5407 (add_file): Remove call to init_misc_bunches.
5409 * mipsread.c: Only warn, don't error, if unknown symbol types.
5410 This keeps an old gdb from falling on its face if it sees newly
5411 extended symbol info. Rename init_misc_bunches.
5413 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
5415 * Merge in changes from Per Bothner for DECstations and other
5416 MIPS stuff. The rest is Bothner speaking:
5418 The next message is a merger of Alessando Forin's mips port with
5419 mine. I've tried to use my good if biased judgment to get
5420 the best of both. It *does* need testing.
5422 Some of the changes are general, *not* mips-specific.
5425 Didn't believe in little-endian bit order.
5426 There are still inconsistencies about whether flags
5427 like BITS_BIG_ENDIAN are integer (#if ...) or
5428 boolean (#ifdef ...). I tried to paper over them.
5430 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
5431 Moved some misc_function code that was common to
5432 {dbx,coff,mips}read.c to symtab.c.
5433 In the process, I think I cleaned things up a bit.
5434 At the same time, moved obsavestring and obconcat to symtab.c.
5437 Removed obsolete condense_addl_misc_bunches (use
5438 condense_misc_bunches(1) instead).
5441 Needed to include <sys/dir>, at least on DECstations.
5443 valops.c, mips-tdep.c, tm-mips.h:
5444 Added PUSH_ARGUMENTS macro to support funny argument-pushing
5445 conventions (when STACK_ALIGN is insufficient).
5446 Needed on mips, where doubles need 8-byte alignment,
5447 but ints only need 4.
5450 Removed cruft that was not being used.
5451 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
5454 Print $ before register-names (I think that makes things a little
5456 Never print two instructions, even if one delays.
5457 Removed hex-disassemble set_cmd. (This is not mips-specific,
5458 so I think the argument is whether it is generally worthwhile or not.
5459 I'm inclined to think not, given how easy it is to
5460 convert between radixes in gdb.)
5463 This is basically Alessando's code.
5464 It doesn't use obstacks; I changed it to use obstacks
5465 in a few minor places where using malloc causes a
5466 memory leak. (Probably, more places could/should be changed.)
5467 I added record_misc_function where it was missing.
5468 In symbol_file_command and add_file_command, I tried
5469 to make the code consistent with more recent versions.
5470 Minor sylistic changes in parse_procedure.
5471 Make a .gdbinfo. psuedo-symbol point back to the real
5472 procedure symbol (using the isym field).
5475 This is basically from my port, but with a lot of details
5476 and a number of routines merged in from Alessando's version.
5477 I basically used my code "raw" backtrace (use heuristics
5478 from the actual code, rather than symbol table info) - though
5479 the idea is Alessandro's. I feel my code is a little cleaner
5480 here, particularly in being a little more flexible, such as being
5481 able to handle gcc-produced code (which it now can).
5482 It also doesn't do frame caching (which is not useful
5483 more recent gdb versions).
5484 I also used my code for push_/pop_dummy, more or less.
5485 I tried to incorporate AF's code for testing sigtramp
5486 while backtracing; I probably got it wrong.
5487 Added mips_print_register, which tries to scrunch as much
5488 information as possible on a screen...
5489 Removed the skip-prologue set_cmd. As with hex-disassemble (see
5490 under mips-pinsn.c), I don't see anything mips-specific here,
5491 and I don't see it being all that useful anyway.
5494 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
5495 Use more register names (rather than hard-cases numbers).
5497 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
5499 * Hack up 3.90.11 changes:
5501 * Makefile.dist (depend): parameterize $(GCC).
5502 Add solib.c and solib.o.
5503 (readline): Fix vpath for both absolute or relative SRCDIR.
5505 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
5506 Also, let the part I didn't understand at least compile so
5507 I can test the rest. FIXME.
5509 * dbxread.c: Fix thinko using strcmp.
5510 (init_psymbol_list): declare static.
5511 (partial_symbol_file_open): Comment cleanups better, avoid
5512 cleaning up the string table since the caller will do that.
5513 Move the stat for mod time into symbol_file_command, temporarily.
5514 (There should be a mod time for each symbol file, eventually,
5515 to control its rereading. FIXME.)
5517 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
5518 SunOS, which gives error for shared libs otherwise. (From
5519 Schaefer, probably FIXME needs work for portability.)
5521 * solib.c: Move #include "param.h" to work.
5522 Lowercase all the Uppercase Letters In the Messages.
5523 (find_solib): Clean up inferior_so_name for debug printouts.
5524 Allow no argument, to mean all shared libraries.
5526 * symmisc.c: include param.h to get CLEAR_SOLIB.
5528 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
5530 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
5531 to 3.90.11. ChangeLog entries below are from this.
5533 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5537 * Makefile.dist (HFILES): Add tm-sunos.h.
5539 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5543 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
5545 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
5547 * sparc-opcode.h Added single-operand version of rett.
5549 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5551 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
5552 Put parens around gcc_p in expansion.
5554 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5556 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
5558 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5560 * Changes for Sun shared libraries:
5561 blockframe.c (find_pc_partial_function): If a non-text symbol
5562 is found, set *address = pc - FUNCTION_START_OFFSET.
5563 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
5564 Disable breakpoints instead of giving an error.
5565 source.c (select_source_symtab): Initialize cs_pst.
5566 symmisc.c: Call CLEAR_SOLIB if defined.
5567 symtab.h: Make text{low,high} CORE_ADDR not int.
5568 (psymtab): New field addr.
5570 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
5571 (record_misc_function): Give correct type for N_DATA symbols.
5572 (condense_misc_bunches): do "misc_function_count = j" regardless
5574 Take code which is shared between symbol_file_command and
5575 add_file_command and put it into partial_symbol_file_{open,read}.
5576 Split add_file_command into add_file_command and add_file.
5577 Make psymtab_to_symtab read in the string table if the file
5579 Two new parameters to read_dbx_symtab and start_psymtab.
5580 tm-sunos.h: New file.
5582 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5584 * infcmd.c: Change cont_command to continue_command and "cont"
5587 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5589 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
5591 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
5593 * values.c (USE_STRUCT_CONVENTION): Check for structures of
5594 size 1,2,4,8 rather than size < 8.
5596 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
5597 as necessary, not just once.
5599 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
5601 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5603 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
5605 * tm-news.h: Add CALL_DUMMY_*.
5607 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
5609 * config.gdb: In list_host, list_target, use ${i}, not $i.
5611 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5613 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
5615 * sparc-opcode.h: Change all store floating-point state register
5616 instructions to have the right match & lose fields.
5618 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5620 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
5622 config.gdb: If srcdir != ., create readline directory and
5623 copy a makefile into it.
5625 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
5626 consistency with POSIX.
5628 * breakpoint.c (bpstat_stop_status): Disable watchpoint
5629 when we exit its exp_valid_block.
5631 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
5633 * Makefile.dist: Bump version to 3.91.3.
5635 * Clean up handling of breakpoint commands (somewhat).
5636 Prompted by Tiemann bug report "cont 10" doesn't work any more.
5638 inferior.h: Add breakpoint_proceeded to inferior status struct
5639 and globals; save it and restore it.
5640 (clear_breakpoint_commands): Cleanup, remove old #define.
5642 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
5643 (save_inferior_status, restore_inferior_status): handle it also.
5644 (proceed): Remove earlier code that set breakpoint_proceeded.
5645 It is now set only in clear_proceed_status.
5646 (clear_proceed_status): Cleanup, use bpstat_clear rather
5647 than clear_breakpoint_commands. No callers need the stop_bpstat
5648 between clear_proceed_status and proceed.
5650 infcmd.c: Add breakpoint_proceeded definition and comment.
5651 (cont_command, jump_command, signal_command): Move call to
5652 clear_proceed_status right next to call to proceed.
5654 breakpoint.c (bpstat_do_actions): Avoid clobbering our
5655 caller's argument while running down the chain of breakpoints.
5656 Use new variable "breakpoint_proceeded" to determine when
5657 a command that it executes moves the inferior past the
5659 (bpstat_clear): Handle NULL argument.
5660 (bpstat_clear_actions): Avoid useless call to
5661 breakpoint_auto_delete.
5662 (delete_breakpoint): Clean up bpstat's that are pointing to
5663 the deleted breakpoint from the stop_bpstat chain.
5664 (breakpoint_auto_delete): Simplify.
5666 * Clean up handling of EOF, error on stdin, etc. This was
5667 prompted by a network problem that caused gdb to go into an
5668 infinite loop filling up its malloc'd memory.
5670 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
5671 not clear_breakpoints_commands, which is now gone.
5672 (main): If command_loop returns (e.g. from EOF on stdin), do
5673 a quit_command (looping back to command_loop if quit_command
5674 doesn't really quit).
5675 (command_loop): check result from command_line_input and
5676 exit if it returns NULL, rather than passing the NULL to
5678 (gdb_readline): Free malloc'd result space before returning
5681 * utils.c (query): Handle C-d to mean "yes", just as if the
5682 input was not a terminal. Also avoid infinite loop if EOF
5683 occurs in mid-input-line before newline. This allows
5684 query to be used at EOF on stdin with reasonable results.
5686 * infrun.c (proceed): Set breakpoint_proceeded.
5688 * values.c (value_as_long): Avoid infinite recursion for enums.
5689 (_initialize_values): Fix typo in help msg (kingdon).
5691 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
5692 RL_LIB for linking. This allows -lreadline for linking
5693 and nothing for dependencies, once readline is a real library.
5695 * config.gdb: Jim Kingdon: give useful error message if the
5696 host or target type is not recognized.
5698 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
5699 it just defines it. Dumb, but deal with it.
5701 * Jim Kingdon suggests:
5702 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
5704 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
5706 * Makefile.dist (VERSION): Bump version # to 3.91.2.
5708 * Clean up Bothner's changes.
5710 * blockframe.c (clear_pc_function_cache): New function.
5711 * blockframe.c: remake cache_pc_function_* static.
5712 * dbxread.c (symbol_file_command): remove references to
5713 cache_pc_function_* variables.
5714 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
5715 * printcmd.c: Avoid kludging a global variable (addressprint)
5716 to avoid printing the address of a string twice. Instead,
5717 pass the format letter 's' down low enough that it can be seen
5718 to avoid this problem.
5719 (print_formatted): Pass format arg to value_print.
5720 (restore_addressprint): Remove function.
5721 (do_examine): Avoid hacking addressprint, cleanups and such.
5722 (print_frame_args): Add a comment to a Bothner change.
5723 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
5724 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
5725 to wipe out the values cached in blockframe.c.
5726 * symtab.c (find_method): Add comment saying how big you must
5727 allocate to be "big enough". Per being terse again.
5728 * valprint.c (val_print): Handle format letter "s" to print
5729 strings without addresses. Add comment to vtbl printing code
5730 which casts with wild abandon. Rearrange reference-printing
5732 @0xaddr: value (print w/addressprint)
5733 value (print w/~addressprint)
5734 @0xaddr (parameter lists w/addressprint)
5735 or nothing (parameter lists w/o addressprint)
5737 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
5739 * Merge more changes from Per Bothner:
5741 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
5742 annoying) that I tried to improve it. Here are my suggestions.
5744 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
5747 Do automatic de-reference when taking the address of a reference.
5749 Don't deref_ref when printing parameter lists.
5751 More attempts at treating refernences properly.
5753 In val_print, if deref_ref==0, don't print dangling " = ".
5755 Add COERCE_REF macro, which de-references an REF.
5757 * Merge changes from Per Bothner:
5759 * Fixed (Sony news)-specific configuration problems.
5760 * Fixed other problems with using vanilla pcc and libc (enum problems;
5761 assumption that vsprintf exists).
5762 * Some major speed-ups (finc_pc_partial_function now caches a match;
5763 parsing avoids duplicate symbol_lookup calls).
5764 * Changed handling of baseclasses (no longer use baseclasses field
5765 of struct type, use the first n_baseclasses fields instead).
5766 * Various minor changes/fixes, most C++-related.
5769 Cache the most previous match from find_pc_partial_function.
5770 (Save both low and high ends of matching function's pc range.)
5771 This speeds up the loop of infrun.c:wait_for_inferior quite
5772 a bit, and makes step/next commands much zippier.
5774 Added an enum->int cast (otherwise, some compilers barf).
5776 No longer set baseclass offset to 0, since multiple
5777 inheritance now mostly works.
5778 Added a number of casts, to shut up compiler warnings
5779 (after stabs where made enums, not ints).
5780 When discarding a symbol table (in symbol_file_command),
5781 must clear the cache introduced in blockframe.c.
5782 Don't convert $vtbl_ptr_type to vtbl any more.
5783 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
5784 Mask off sign bit emitted by g++ for virtual table offset.
5785 Set voffset to -1 (not 1) for static member functions.
5787 Changed parsing/lexing of names to avoid doing symbol lookup twice
5788 (once when lexing to determine symbol class, once for real).
5789 Now only call symbol_lookup once. Fields of 'this' win especially big.
5791 Subpress printing addr twice in the case of 'x/s addr'.
5793 lookup_basetype_type is no longer used.
5794 Add find_methods as recursive helper function to decode_line_1.
5795 This allows multiple inheritance to work.
5796 Also, once one or more matches has been found, do not look in
5797 base-classes. (Baseclass methods would be overridden, anyway.)
5799 Removed baseclasses array in struct type.
5800 Instead of using baseclasses[i], use fields[i-1].
5801 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
5802 Changed sign convention of voffset (previous was inconsistent).
5804 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
5806 Used to assume existence of vsprintf. Re-written to not need it
5807 if HAVE_VPRINTF is undefined.
5809 typecmp was too pessimistic. Made it less so.
5811 Don't print space after address.
5812 If vtable points to a misc symbol (with 0 offset), print it,
5813 since that indicates the actual class of the object.
5814 Changed ype_print_derivation_info to use new inheritance
5815 scheme (without baseclasses vector).
5817 In value_primitive_field, fixed some bugs left over from previous set of fixes.
5818 Also, changes needed because TYPE_BASECLASSES were removed.
5820 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
5822 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
5825 If there is no path set, and the symbols don't indicate what directory
5826 a file was compiled in, look in the current directory. But either
5827 a path or a known compilation directory will prevent this.
5830 Three independent bug fixes:
5831 * Remove the #if 0 block that breaks some stuff.
5832 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
5833 adapt gdb to either SunOS 4.0.* or 4.1.
5834 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
5837 Instantiate the class T when looking for methods in it. (Tiemann@sun)
5840 (type_print) Demangle the name being printed.
5841 (type_print_base) Handle botched demangling without coredump (tiemann).
5844 (check_stub_method): Document routine.
5845 (tiemann) fix bug for no-arg functions
5846 Avoid clobbering beyond end of malloc'd storage.
5847 Terminate the argument list properly.
5849 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
5851 * Changes merged by John Gilmore:
5854 In breakpoint_1, use new print_address_symbolic instead
5855 of find_pc_partial_function. (This forces use of assembler-level
5856 addresses, and avoids misleading non-mangled source-level names.)
5858 Generalize ansi argument such that -1 means skip arglist totally.
5859 Removed global variable print_ansi_qualifiers (which made
5860 code non-reentrant), in favor of extra explicit arguments
5861 to internal routines.
5863 Add new helper function print_address_symbolic.
5864 Use find_pc_misc_function instead of find_pc_partial_function
5865 (since we want assembler-level symbols here).
5867 Print unknown function as just "f (...)", not "f (...) (...)".
5868 Use new fputs_demangled explicitly.
5870 Fixed a typing violation (problem: value.h cannot be imported
5871 without renaming many variable in this file).
5872 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
5873 decode_line_1: Moved forward some never-reached code.
5874 Made decode_line_2 skip function prologues correctly.
5876 fputs_filtered should not demangle by default.
5877 Add new fputs_demangled to demangle on demand..
5879 Change value_struct_elt to use value_primitive_field (using recursive
5880 utility function search_struct_field). This allows foo.bar to work
5881 for multiple inheritance (so far only for data fields).
5882 Change check_field in the same way (recursive helper function
5883 to support multiple inheritance).
5884 (Note: there are more of these problems that I haven't fixed.
5885 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
5886 value_of_this: 'this' symbol name is now just "this", note "$this".
5888 Don't print static members.
5889 Avoid printing "members of <type>" if there are none.
5890 Simplified type_print_derivation_info by merging duplicate code.
5891 Remove useless blank lines in type_print_base (ptype command).
5893 Added declaration of new routine value_primitive_field.
5895 Added value_primitive_field which is generalized version of
5896 value_field that can handle multiple inheritance (non-zero offsets etc).
5897 Re-implemented value_field to call value_primitive_field.
5899 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
5901 * infcmd.c -- insert else to avoid 'delete env' coredump when you
5902 delete the whole environment. Karl Berry reported the bug.
5903 * source.c - fix openp to avoid //'s in filenames, which
5904 trigger an Emacs bug causing it to not be able to find files
5905 when running gdb in a window.
5906 * dbxread.c - zap the #if 0 that botches the add-file code.
5907 It seems to work a lot better without all the code commented out.
5909 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
5911 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
5914 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
5916 * Makefile - added a ${CFLAGS} to a couple of entries,
5917 added remote-sa.sparc.c
5918 * added remote.sa-sparc.c, a modification of remote.c
5919 which conducts a dialog directly with the SparcStation prom.
