1 Thu Nov 7 18:26:15 1991 Steve Chamberlain (sac at rtl.cygnus.com)
3 * m88k-xdep.c: Fixed the register offsets in the ptrace_user
4 struct for BCS 88k machines.
5 * xm-m88k.h: don't define USIZE if already defined.
6 * configure.in: Added delta88 target.
8 Thu Nov 7 04:51:19 1991 John Gilmore (gnu at cygnus.com)
10 * am29k-pinsn.c, am29k-opcode.h: Fix decoding of mtacc, dmac, fmac.
12 * tm-*.h: Remove READ_DBX_FORMAT, COFF_FORMAT, and
13 READ_MIPS_FORMAT, which have been unused since BFD. Still
14 remaining is COFF_NO_LONG_FILE_NAMES.
15 * tm-sun3.h, tm-altos.h: Remove detritus accidentally left from
16 function calling code moved to m68k-tdep.c.
18 Wed Nov 6 17:21:59 1991 John Gilmore (gnu at cygnus.com)
20 * coffread.c: Eliminate c_nsyms in favor of c_naux.
21 Complain if no auxents on .bf and .ef FCN symbols, and assume
23 (init_linenos, enter_linenos): Use a sentinel at the end of the
24 read-in linenos, to make for a fast, safe loop-end test.
26 Wed Nov 6 02:54:08 1991 Steve Chamberlain (sac at cygnus.com)
28 * coffread.c (read_coff_symtab): coffread used to rely on the
29 x_sym.x_misc.x_lnsz.x_lnno field giving the # of linnos in a
30 function. Two of the formats I'm using (29k and 88k) don't seem to
31 set it. Ths patch to fcn_last_line and (enter_linenos) is an
32 attempt to use the actual size of the linno table in the file to set
33 the number of linenos to process.
35 Tue Nov 5 22:47:46 1991 Steve Chamberlain (sac at cygnus.com)
37 * Makefile.in: put a - infront of the mv y.tab.c c-exp.tab.c and
38 mv y.tab.c m2-exp.tab.c, so that if bison is used, and the files
39 are created in place, so the mv fails, then the make continues.
41 Tue Nov 5 16:47:47 1991 Per Bothner (bothner at cygnus.com)
43 Add C++ as a separate language.
44 * defs.h (enum language): Add language_cplus.
45 * dwarfread.c (end_symtab): Support language_cplus.
46 * c-exp.y: Add new struct language_defn cplus_language_defn.
47 Don't set c to be the default language (see main.c).
48 * c-exp.y (yylex): Only look for field of this if
49 language is C++. (First difference from C!)
50 * language.c: Add case branches for C++ (currently, all
51 the same as C). Also, add c++ to "usage" note for "set lang".
52 * valprint.c (typedef_print). Add case branches for C++.
53 * main.c (main): New way to set initial language: Look at
54 file extension of psymtab containing main(). (Same as we
55 do for symtabs, but avoid loading the symtab yet.)
56 * symtab.c: New routine find_main_psymtab(), used by main()
57 to set initial language.
58 * symfile.c (allocate_symtab): Move code for mapping file
59 extensions-> languages to new deduce_language_from_filename().
61 Fix a C++ problem when looking for methods in super-classes.
62 There was confusion between base and derived types.
63 * valops.c (value_fn_field): Change function interface.
64 * values.c: Use new value_fn_field interface.
66 Mon Nov 4 10:49:33 1991 Per Bothner (bothner at cygnus.com)
68 * infrun.c: Fixed typo in comment.
69 * utils.c: All the v*fprintf emulation is now in libiberty,
70 so we can get rid of some junk.
71 * xm-sun3os4.h, xm-sun4os4.h, xconfig/decstation, xconfig/i386sco,
72 xconfig/sun3os4, xconfig/sun4os4: Don`t need HAVE_STRSTR any more.
73 * m68k-pinsn.c (print_insn_arg): Support BB/BW/BL
74 type operands, as used by branch instructions.
75 * gmalloc.c: Fix prototype of memcpy.
76 * elfread.c: Comment out register_addr, since it conflicts
77 with the one in coredep.c.
78 * buildsym.h: Remove extern declarations of two functions
79 that are really static in buildsym.c.
80 * tm-mips.h: Add symbolic names for more registers.
81 * mips-xdep.c (store_inferior_registers): Use new register names.
82 * xm-mips.h: Simplify REGISTER_U_ADDR, since it is now
83 only used for core files, not ptrace. Therefore,
84 the KERNEL_U_ADDR hack is no longer needed.
85 The mapping to ptrace number is now in in mips-xdep.c.
86 * mips-xdep.c: Define REGISTER_PTRACE_ADDR (using the
87 mapping from the old REGISTER_U_ADDR), and use it
88 in {fetch,store}_inferior_registers.
89 * mipsread.c: Rename #include ecoff.h to new name coff-mips.h.
90 * mips-tdep.c (mips_push_dummy_frame, mips_pop_frame):
91 Save/restore FP regs correctly (?).
92 * dbxread.c: Remove duplicate define_symbol and type_synonym_name
93 (these had been previously moved to buildsym.c).
94 Hence, define_symbol becomes extern instead of static.
95 * buildsym.c (read_struct_type): Comment out bogus handling
96 of C++ operator methods. Minor hacking of reading of class
97 contexts. Make define_symbol non-static, so dbxread.c can call it.
99 Fri Nov 1 11:05:47 1991 John Gilmore (gnu at cygnus.com)
101 * mipsread.c (read_mips_symtab, read_the_mips_symtab): Use real
102 filename with error messages.
103 * stack.c (frame_select_command): Rename to select_frame_command
104 to avoid "fr" and "fra" having nonunique completions.
105 * symfile.c (sort_symtab_syms): Ignore sort of zero symtab *.
106 (symfile_init): Print file format name when unable to handle it.
107 (free_named_symtabs): Use BLOCKVECTOR rather than obsolete BLOCKLIST.
108 * symmisc.c (free_symtab): Only free linetable if nonzero.
109 * symtab.h: Remove obsolete BLOCKLIST macros.
111 Thu Oct 31 18:12:43 1991 Stu Grossman (grossman at cygnus.com)
113 * infrun.c (wait_for_inferior): another stepi/nexti fix. Ensure
114 that stop_step is 1 at bottom of main loop. I don't know why this
115 needs to be done, but it helps me sleep better at night.
117 Sun Oct 27 18:18:39 1991 Stu Grossman (grossman at cygnus.com)
119 * main.c (initialize_history): Read history after reading all
122 Sun Oct 27 14:09:25 1991 John Gilmore (gnu at cygnus.com)
124 * buildsym.c: Break out initial malloc sizes.
125 (record_line): Record directly in a subfile. Alloc on demand.
126 (compare_line_numbers): Add from xcoffread.c.
127 (end_symtab): New params say whether to sort pendings and
128 linetable. Patch block stabs if defined. Shrink linetable before
129 allocating the symtab.
130 * buildsym.h: Delete line_vector* and prev_line_number. Add
131 global_stabs and file_stabs for xcoffread.
132 * dbxread.c (start_subfile): Move to buildsym. Change above calls.
133 * symtab.h: LINETABLE(symtab) can now be null. Zap LINELIST.
134 * symmisc.c, symtab.c: Cope with null LINETABLEs.
136 * blockframe.c: Pass fromleaf to INIT_EXTRA_FRAME_INFO.
137 * tm-29k.h, tm-88k.h, tm-i960.h, tm-irix3.h, tm-mips.h, tm-pyr.h,
138 tm-sparc.h: Accept fromleaf parameter.
139 * c-exp.y (yyerror): Pass error message if given.
140 * configure.in: Add rs6000 host and target.
141 * inflow.c (new_tty): O_NOCTTY kludge for RS/6000.
142 * symfile.h (entry_point): Add.
144 Sat Oct 26 00:16:32 1991 John Gilmore (gnu at cygus.com)
146 * buildsym.c: New file. Breaks out symbol-table-building routines
147 from dbxread.c, so they can be shared with xcoffread.c.
148 * buildsym.h: New file. Declarations for buildsym.c users.
149 * dbxread.c: Remove large chunks into buildsym.c.
150 * Makefile.in: Add buildsym.c and buildsym.h.
152 * symfile.c (syms_from_bfd): New routine.
153 (add_symbol_file): Call it to do the real work.
154 (syms_from_bfd): Initialize entry_point before calling symfile_init.
155 * symtab.h, symfile.c, coffread.c, mipsread.c, dwarfread.c:
156 Avoid declaring or setting entry_point (symfile.h & symfile.c cope).
158 Fri Oct 25 18:59:32 1991 Per Bothner (bothner at cygnus.com)
160 Various fixes to improve g++ debugging.
161 * symtab.h: Add is_const and is_volatile flags for each method.
162 These are bit fields - take their space from voffset,
163 which shrinks to 30 bits. Since voffset is now a bitfield,
164 make it unsigned for portability. This changes its interpretation
165 slightly: Static methods now have voffset 1 instead of -1,
166 and virtual offsets start at 2, not 1.
167 * symtab.c: Renamed gdb_mangle_typename to gdb_mangle_name,
168 since it now returns an entire magled method name, not just
169 the type part. This avoids some duplication.
170 It also allows us to correctly mangle const and volatile
171 methods (using the new is_const and is_volatile bit fields
173 * valprint.c (type_print_base), values.c (check_stub_method):
174 Simplify by using new gdb_mangle_name.
175 * values.c (value_headof): Fix to correctly handle single
176 inheritance (actually two fixes, either of which suffices).
177 * dbxread.c (read_struct_type): Handle const and volatile
179 * dbxread.c (read_struct_type): Yet one more place where
180 we must handle '\\' continuations.
181 * valprint.c (vtbl_ptr_name): Add final '\0'.
183 Fri Oct 25 16:06:38 1991 Stu Grossman (grossman at cygnus.com)
185 * tm-sparc.h, tm-68k.h (EXTRACT_RETURN_VALUE): fix output of
186 short return values for sparc and 68k. Patch from Paul Eggert.
188 * coffread.c, coredep.c, i386-xdep.c: install patches for
189 SysV/386 3.2 from Mauro DePalma.
191 Fri Oct 25 02:02:13 1991 John Gilmore (gnu at cygnus.com)
193 * core.c (core_file_info), exec.c (exec_file_info): Print file
194 type. Use printf_filtered.
196 * valops.c (value_fetch_lazy): Avoid 0-length fetches.
198 Thu Oct 24 23:06:40 1991 Fred Fish (fnf at cygnus.com)
200 * dwarfread.c: Add casts to remove compiler warnings.
202 * tm-3b1.h, tm-68k.h, tm-altos.h, tm-amix.h, tm-hp300bsd.h,
203 tm-hp300hpux.h, tm-isi.h, tm-news.h, tm-pn.h, tm-sun2.h,
204 tm-sun3.h: Remove locally duplicated code for calling functions
205 in the inferior. The only differences were in the specific trap
206 vectors used and whether or not an fpu was present. These are
207 now handled by appropriate definitions of BPT_VECTOR and
208 HAVE_68881 respectively. Other minor obvious cleanups.
210 * valops.c: Correct a minor misspelling.
212 * utils.c: Remove local BSD/USG hacks that are now in libiberty.
214 * dwarfread.c: Remove prototype for dwarfwarn. Does not work
217 Thu Oct 24 09:33:44 1991 John Gilmore (gnu at cygnus.com)
219 * stack.c (frame_command): Always print. Use new
220 frame_select_command to select a frame without printing.
222 * dwarfread.c: Use <varargs.h>, since <stdarg.h> is not portable.
224 Thu Oct 24 01:32:51 1991 Fred Fish (fnf at cygnus.com)
226 * dwarfread.c: New file for DWARF debugging format support.
228 * elfread.c: New file for ELF object file format support.
230 * procfs.c: New file for SVR4 /proc (process file system) support.
232 * tm-amix.h, xm-amix.h, tconfig/amix, xconfig/amix: New files for
235 * xm-svr4.h, tm-svr4.h: New files for SVR4 support.
237 * xm-m68k.h: New file for host machines with m68k cpu.
239 * Makefile.in: Add elfread.c and dwarfread.c to SFILES_MAINDIR.
240 Add elfread.o and dwarfread.o to OBS.
242 * symfile.h: Add "elf" to list of supported formats in comment.
244 * c-exp.y, defs.h, symtab.h, valprint.c: Add three new builtin
245 types to gdb, builtin_type_long_double, builtin_type_complex, and
246 builtin_type_double_complex. Add and use new TARGET_SHORT_BIT,
247 TARGET_INT_BIT, TARGET_LONG_BIT, TARGET_FLOAT_BIT,
248 TARGET_DOUBLE_BIT, TARGET_LONG_DOUBLE_BIT, TARGET_COMPLEX_BIT, and
249 TARGET_DOUBLE_COMPLEX_BIT, as the sizes in bits of the indicated
250 types on the target machine (ala the existing TARGET_LONG_LONG_BIT).
252 * infrun.c: When using SVR4 /proc interface instead of ptrace(),
253 call proc_set_exec_trap() to setup child to stop at first instruction.
255 * inftarg.c: When using SVR4 /proc interface, call proc_wait()
258 * m68k-tdep.c: Add new routines supply_gregset(), fill_gregset(),
259 supply_fpregset(), and fill_fpregset(), which are machine
260 dependent support routines for SVR4 /proc interface.
262 * utils.c: Add warning_setup() and warning(). Warning() behaves
263 the same as error() except that it returns normally rather than
264 jumping back to command level. Modules that don't want to call
265 warning() for some reason, but want to produce their own warnings,
266 can call warning_setup() to ensure compatibility with the way
267 warning() and error() deal with the terminal.
269 * symtab.c: Make internal errors produce more useful messages.
271 * tm-68k.h: Move code that is duplicated in almost every single
272 m68k based machine's configuration files to this common file.
273 Duplications in the configuration files still need to be removed
276 * infrun.c (child_create_inferior): System V versions must call
277 setpgrp() with no arguments, to comply with prototyping typically
280 * munch: Add support for SVR4 style nm output.
282 * dbxread.c, mipsread.c symmisc.c, symtab.c: Remove the object
283 file specific fields from the partial symbol table structure and
284 replace them with a pointer to private data for each different
285 flavor of object file reader to initialize appropriately.
287 Wed Oct 23 09:38:20 1991 John Gilmore (gnu at cygnus.com)
289 * xconfig/sun[34]os4: Add note about strstr botch on sunos4.0.3c
292 * mipsread.c (fixup_undef_type): New function. If a struct /
293 union / enum is defined in a header file but nowhere else used,
294 (by typedefing, pointer referencing or declaration) the mipsread code
295 builds the complete tree for the structure but leaves its code as
296 TYPE_CODE_UNDEF as it doesn't know what kind of aggregate it is.
297 Guess its type based on the details of the members.
299 Tue Oct 22 18:04:32 1991 Stu Grossman (grossman at cygnus.com)
301 * infrun.c (wait_for_inferior): Check return value from
304 Mon Oct 21 17:47:03 1991 Stu Grossman (grossman at cygnus.com)
306 * infrun.c (wait_for_inferior): fix stepi/nexti that was broken
307 by my last edit to this routine.
309 Mon Oct 21 14:27:43 1991 John Gilmore (gnu at cygnus.com)
311 * tm-sun3.h (FIX_CALL_DUMMY): problem with cross debugging.
312 FIX_CALL_DUMMY does unaligned accesses and/or forgets to byte swap
313 the values before putting them into the dummy code. (From Peter
316 Mon Oct 21 10:04:39 1991 Steve Chamberlain (steve at rtl.cygnus.com)
318 * configure.in: added ebmon target.
320 Wed Oct 16 22:49:58 1991 John Gilmore (gnu at cygnus.com)
324 * Makefile.in: Roll VERSION to 4.2.
325 * README, TODO, WHATS.NEW: Update.
327 * core.c (core_open): Improve error message for bad file.
328 Pass .reg virtual memory address to fetch_core_registers to help
329 it find the registers in the core-file header.
330 * coredep.c (fetch_core_registers): Take new argument, use it,
331 and pass it to register_addr to locate the block of registers.
332 * xm-mips.h: Update KERNEL_U_ADDR for new scheme. Cleanup a bit.
334 * dbxread.c (read_dbx_symtab, process_one_symbol): Handle
335 Sequent N_FN_SEQ like everybody else's N_FN.
337 * main.c: Circumvent SCO cc bug with #if !!defined(USG).
338 * tm-i386v.h: #endif guck.
339 * xconfig/i386*: Remove -Dgetpagesize()=4096 kludge.
340 * xconfig/i386sco: Add HAVE_STRSTR to avoid ANSI bdeath.
341 * xconfig/tahoe: Add REGEX, which seems to be missing.
343 * coredep.c: Add <sys/types.h> for SCOnix.
344 * dbxread.c (read_dbx_symntab): Avoid coredump on malformed file.
345 * printcmd.c (print_formatted): Flush output before disassembly.
347 Tue Oct 15 20:12:32 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
349 * doc/refcard.tex (sec "Working Files"): consistent metavars and
350 other improvements, due to comments by François Pinard
351 (pinard@iro.umontreal.ca)
353 * doc/gdb.texinfo (appendix "Installing GDB"): changes in
354 configure, and improvenets related to Pinard's refcard comments
356 Tue Oct 15 08:45:12 1991 John Gilmore (gnu at cygnus.com)
358 Changes from Fred Fish:
359 * tm-68k.h (FPI_REGNUM): Add.
360 * infrun.c (child_create_inferior): flush stdout and stderr
362 * configure.in: Handle amigados, amix hosts and targets.
363 * inflow.c: Handle TIOCGLTC_BROKEN for Amiga.
366 * values.c (show_convenience): Use printf_filtered.
367 * main.c (define_command): Check result of lookup_command for
369 (echo_command): Use printf_filtered, and force output out.
371 * dbxread.c (read_enum_type): Avoid Modula-2 kludge that breaks C
373 * i387-tdep.c (double_to_i387): Fix typo for double_to_ieee_extended.
374 * utils.c (_initialize_utils): If !ISATTY, don't paginate.
375 * configure.in, tconfig/decstation, xconfig/decstation: Rename
376 dec3100 to decstation.
378 Mon Oct 14 13:37:50 1991 Roland H. Pesch (pesch at cygnus.com)
380 * doc/gdb.texinfo: Catch up to changes recorded here in ChangeLog
381 (nodes Continuing and Stepping; Memory; Targets) clarifications
384 Fri Oct 11 23:27:06 1991 John Gilmore (gnu at cygnus.com)
386 * tm-{irix3,mips,nindy960,pn,symmetry,vx960}.h: Move
387 REGISTER_U_ADDR to corresponding xm- file. Sugg. by Peter Schauer.
389 * symmisc.c (print_partial_symtabs): Add printpsyms debug cmd.

392 generic routines for calling inferior functions.
394 * blockframe.c (inside_main_scope, inside_entry_scope): New.
396 * copying.awk: Filter formfeeds out of copying & warrantee.
397 Make them available as `show copying' and `show warrantee' also.
398 * main.c (print_gnu_advertisement): Advt `show' commands.
400 Thu Oct 10 17:25:47 1991 John Gilmore (gnu at cygnus.com)
402 * mach386-xdep.c: Even when cross-compiling, leave in the
403 core-file reading code.
404 * core.c (get_core_registers): Avoid coredump if no .reg section.
406 Wed Oct 9 17:03:34 1991 John Gilmore (gnu at cygnus.com)
408 * mipsread.c, coffread.c: initialise TYPE_VPTR_FIELDNO to -1.
409 This avoids coredumps under `set print object on' in value_headof
410 (called erroneously by value_from_vtable_info) for `p &struct'
411 or `p *struct'. From Peter Schauer.
413 Mon Oct 7 00:06:52 1991 John Gilmore (gnu at cygnus.com)
415 * Makefile.in: Roll version to 4.1.2.
416 * dbxread.c: Use aout64.h, not a.out.gnu.h. Get external symbol entry
417 size from BFD (but, FIXME, we don't yet read external nlists's and
418 convert them to internal nlists's before handling them -- we still
419 assume they have the same size and alignment.) Use SET_NAMESTRING
421 * exec.c (exec_file_command): Move dead coff-encapsulation code
423 * m88k-tdep.c, m88k-xdep.c: Remove encap test and #inc <a.out.h>.
425 Fri Oct 4 22:30:06 1991 John Gilmore (gnu at cygnus.com)
427 * configure.in, tm-i386v.h, xm-i386v.h: Intel 386 Mach host port.
428 * xm-i386mach.h, mach386-xdep.c, xconfig/i386mach: New files.
430 Fri Oct 4 17:04:31 1991 Per Bothner (bothner at cygnus.com)
432 More patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
433 * mips-xdep.c (store_inferior_registers): Don't try to
434 write the (pseudo) FP.
435 * mipsread.c (parse_partial_symbols): Improved algorithm for
436 setting pst->texthigh.
438 Fri Oct 4 16:47:32 1991 Roland H. Pesch (pesch at cygnus.com)
440 * doc/Makefile: make TEXINPUTS include . everywhere
442 Fri Oct 4 00:35:56 1991 John Gilmore (gnu at cygnus.com)
444 * coffread.c, dbxread.c, symfile.c, symmisc.c, symtab.h: Remove
445 vestiges of typevectors, which were for symsegs and are no longer
446 used. (From a question by Eliot Dresselhaus
447 <dresselh@RFT30.nas.nasa.gov>).
449 Thu Oct 3 09:33:26 1991 John Gilmore (gnu at cygnus.com)
451 * dbxread.c, coffread.c: static-ize functions that were
452 gratuitiously external. (From Fred Fish.)
454 * c-exp.y: sym->class to SYMBOL_CLASS (sym).
456 * dbxread.c (dbx_lookup_type): Keep doubling size of typevector
457 until it is large enough.
459 * dbxread.c (read_type): Handle error case slightly better.
460 Make complaint message not C++-specific.
462 Wed Oct 2 17:21:07 1991 Stu Grossman (grossman at cygnus.com)
464 * infrun.c (wait_for_inferior): Fix step/next so that you only
465 stop at the beginning of a new line. This fixes various problems
466 with for loops, nested if-else's and switch statements.
468 Tue Oct 1 06:33:55 1991 John Gilmore (gnu at cygnus.com)
470 * symtab.c (lookup_symtab_1, lookup_symbol): "fatal" errors
471 between symtabs and psymtabs become ordinary error()s.
473 * dbxread.c (read_dbx_symtab): Relocate end_of_text_addr
474 properly, making "end pc" correct in shared lib psymtabs.
475 (From Guy Harris <guy@auspex.com>.)
477 Mon Sep 30 13:15:31 1991 John Gilmore (gnu at cygnus.com)
479 * dbxread.c: Enable, but soften, const_vol_complaint.
480 (read_dbx_symtab): N_STSYM and N_LCSYM define static vars.
481 Ditto Gould N_NBSTS and N_NBLCS. Also, all types in the psymtab
482 should be file-scope, not global.
483 (read_struct_type): Remove ancient multiple-inheritance warning.
484 (read_range_type): Check base type, complain & patch if undefined.
485 * stack.c (frame_info): Demangle the function name in `info stack'.
488 Sat Sep 28 10:02:33 1991 John Gilmore (gnu at cygnus.com)
490 * eval.c (evaluate_subexp_for_address): Don't use
491 TYPE_POINTER_TYPE directly (it might be zero if this type has
492 never had a pointer created before); use lookup_pointer_type.
493 * symtab.c (lookup_method_type): Arguments were swapped in all
494 callers, so fix it here. I'm amazed this worked at all!
496 Fri Sep 27 18:09:31 1991 John Gilmore (gnu at cygnus.com)
498 * c-exp.y, m2-exp.y: Define more yysymbols that happen to be
499 "bss" rather than "data" symbols, but which still conflict.
502 * coffread.c (coff_symfile_read): Use xmalloc, not malloc.
503 * core.c (core_files_info): Shorten output.
504 * exec.c (exec_files_info): Ditto.
505 (build_section_table): Ignore zero-length sections.
506 * language.c, printcmd.c: Lint.
507 * language.h (get_frame_language): Declare.
508 * saber.suppress: update.
509 * stack.c (find_relative_frame): Remove complex code that was
510 #if 0'd, stick with simple code. Lint.
511 * saber.suppress: Update a bit.
512 * symfile.c (add_symbol_file_command): Add "?" to question.
513 * utils.c (parse_escape): Avoid \a due to bdead compilers.
514 * value.h: Declare typedef_print.
516 * valprint.c (val_print, type_print_base): TYPE_CODE_RANGE less
519 * nindy-tdep.c (nindy_frame_chain_valid): Use lookup_misc_func.
520 (Reported by Mark Peek <mark@imagen.com>.)
522 * solib.c (solib_map_sections): Relocate all sections, even
523 though only the text section's size is tracked. Mark ld_text
524 for eventual elimination as we generalize to N sections.
526 * infrun.c (wait_for_inferior): Don't check if the PC is in a
527 call_dummy if we were stopped by a random signal that is being
528 passed to the program. This produced wierd results when calling
529 functions in the inferior and signals (e.g. SIGALRM) were in use.
531 Tue Sep 24 18:05:30 1991 John Gilmore (gnu at cygnus.com)
533 * infrun.c (IN_SIGTRAMP): Not parenthesized properly.
534 Bugfix from Paul Eggert <eggert@twinsun.com>.

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

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

752 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
754 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
755 entries are enclosed herein. Not all of these changes
756 have been merged into the master GDB sources -- check the
757 ChangeLog above here for the merge log.
759 Mon Jun 3 17:05:45 EDT 1991
761 m2-exp.y Created. Tested outside of GDB for a few days. Proper
762 operators were added, C specific operators and tokens
763 removed. yylex() revamped to some extent. Still things
764 missing from the grammar, such as sets.
765 Tested for two weeks in GDB v3.5.
767 Tue Jun 11 17:23:48 EDT 1991
769 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
770 so they are built-in. Sort of a hack.
772 Fri Jun 14 12:53:51 EDT 1991
774 m2-exp.y Added range checking for numeric constants. Any numeric
775 constant is assumed to be of builtin type INTEGER unless:
776 (1) it is octal or hexadecimal, in which case it is a
777 CARDINAL; (2) it is too big to fit into an INTEGER, in
778 which case it is a CARDINAL.
779 eval.c Added simple range checking for +, -, and * on integers.
780 Doesn't work very well for *, since 6 * 1,000,000,000 =
781 1,705,032,704, which fails the simple test of result >=
782 first_operand, no matter in what order the operands are.
784 Tue Jun 18 14:11:30 EDT 1991
786 Broke the parser into parts, one containing the C grammar and the other
787 containing code to be shared by all of the grammars.
789 The following files no longer exist:
794 The following files were added:
796 c-exp.y (The C grammar)
797 m2-exp.y (The Modula-2 grammar)
798 parser-code.c (Code that is shared by the above grammar)
802 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
803 now necessary to use the Bison compiler compiler, since it
804 will generate function/variable prefixes other than yy.
806 Tue Jun 18 16:47:49 EDT 1991
808 symtab.[ch] Added the external variable working_lang, than holds the
809 value of the current working language.
810 Added the ennumerated type language_mode, with the values
811 language_auto and language_manual, the former meaning that
812 GDB sets working_lang as needed, and the latter meaning
813 that the value of working_lang is totally under user
815 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
816 REAL, BOOLEAN and CHAR. Also added the type codes
817 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
818 utils.c Added set_language_command and show_language_command to
819 implement the GDB support commands "set language" and
821 expression.h A number of identifiers were added to the type exp_opcode
822 to facilitate Modula-2 builtin functions, integer
823 division, and array indexing.
825 Wed Jun 19 13:25:58 EDT 1991
827 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
828 if the language specified by working_lang requires the use
829 of strict typing of expressions. Eventually, even this
830 will be able to be changed by the user.
831 Added the macro RANGE_CHECK, which evaluates to non-zero
832 if the language specified by working_lang requires the
833 checking of a value against the domain of its type.
834 Eventually, even this will be able to be changed by the
836 language.[ch] Predicates involving types (simple_type, ordered_type,
837 same_type, integral_type, numeric_type, character_type,
838 boolean_type, float_type) are added. These predicates are
839 based on the current value of working_lang, and are handy
842 Wed Jun 19 15:39:34 EDT 1991
844 eval.c Added the function type_array_rank which computes the rank
846 valarith.c Added the funtion value_bool, which when given a integer
847 value.h value (ie. struct value *) as an argument, it returns a
848 boolean value (ie. struct value *) true if that integer
849 is non-zero, and a boolean value false otherwise.
850 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
851 will print out properly.
853 Wed Jun 19 16:36:34 EDT 1991
855 valops.c Added the function value_capitalize, which returns it
856 value.h argument capitalized if its argument is a lowercase
857 letter, or the argument unchanged if its argument is not a
859 valarith.c Added the function range_check_p, which returns non-zero
860 value.h if its value argument is between the integral bounds upper
862 Added the function range_check_enum_p, which makes sure
863 that its value argument is a valid member of the domain of
865 Added the function range_check_range_p, which makes sure
866 its value argument lies between the upper and lower bounds
867 of its type argument, which must be a ranged type.
868 Added the function check_array_index, which range and type
869 checks an index of an array.
870 Added the function value_multi_subscript, which computes
871 array[idx1,idx2...idxN], given a value array and an array
872 of values representing indicies.
873 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
874 unpack_long to work with TYPE_CODE_BOOL and
877 Wed Jun 19 18:04:08 EDT 1991
879 symtab.c Stored pervasive types in a structure and make
880 lookup_pervasive_type() a lookup function that was based
881 on working_lang. If lookup_pervasive_type() returned
882 non-zero, then that value was returned (a fix, since
883 before it simply wouldn't return the pervasive type.)
884 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
885 non-zero if the language specified by working_lang means
886 "conversion" when it says "cast".
887 valops.c Added the function value_real_cast(), which performs a
888 value.h *cast*, not a *conversion*, which is what value_cast()
889 does when it can. In particular,
890 value_cast(<float_type>,4) = 4.0, while
891 value_real_cast(<float_type>,4) = some mess.
892 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
893 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
894 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
895 and MIN on integral types. *NOTE*: These are currently
896 hardcoded to work only if there are 8 bits per storage
898 eval.c Made logical functions call value_bool to return a
899 properly typed boolean value, based on working_lang.
901 Thu Jun 20 11:55:27 EDT 1991
903 valprint.c Types now print out in a Modula-2 fashion. This works for
904 the cases when the type is printed out step-by-step, that
905 is, it doesn't work when the name of a structured type
906 (which includes the keyword "struct", etc.) is simply
908 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
909 since type specifications in C and Modula-2 are very
910 different. The C printing of a type is very recursive,
911 whereas in Modula-2 it is generally very simple. C has
912 type prefixes and suffixes, which have no real analogue in
913 Modula-2. Maybe type_print() should call a language
914 specific type printer. This is also advantageous if we
915 compile GDB to exclude some of the languages. We'll just
916 leave those functions out.
918 Thu Jun 20 16:57:10 EDT 1991
920 dbxread.c When reading the complete symbol table in (via
921 psymtab_to_symtab()), the number and types of function
922 arguments are added to a function type. define_symbol()
923 calls add_param_to_type() to accomplish this.
924 Assumption: when we come across a function definition
925 (N_FUN symbol with an 'f' or 'F' in the name), its
926 arguments will appear before another function definition.
927 When a function is found, a pointer to its type is placed
928 in the global in_function_type. Changes that
929 add_param_to_type() makes are to this global.
930 valprint.c The type of a function now includes (for Modula-2) the
931 types of its parameters.
932 eval.c Type checking and a check for the proper number of
933 arguments is now done for function calls. Not sure of the
934 impact this has on C++ member function yet.
936 Thu Jun 20 19:58:48 EDT 1991
938 valprint.c Rewrote the type printer. Broke it into two language
939 specific parts, adding the functions type_print_m2() and
941 An unfortunate consequence is this: if you debugging a C
942 program in Modula-2 mode (why?), info types does not work
943 well with regular expressions, since the types are printed
944 out in Modula-2 terminology, but stored in C terminology.
945 language.[ch] Added the functions new_type_last(), type_keyword(), and
946 type_sep() to aid in the printing of typedefs.
947 symtab.c Made the printing of typedefs as language independent as
948 possible through calls to new_type_last(), type_keyword(),
951 Fri Jun 21 11:50:26 EDT 1991
953 dbxread.c Check all incoming ennumerated types. If it looks like
954 Modula-2's BOOLEAN type, then change the type_code of the
955 type to TYPE_CODE_BOOL so we can process it as a boolean
957 valprint.c Replaced some of the 0x%x with calls to sprintf and
958 hexformat() in val_print().
959 language.[ch] Added the function hex_to_string(), which converts its
960 integral argument to a hexadecimal number (format is
961 language based) and returns the result as a string.
963 Mon Jun 24 12:25:07 EDT 1991
965 valprint.c Some functions call type_print_1() directly, instead of
966 value.h using type_print(), so they can specify where (column) to
967 print things. Since type_print() takes care of language
968 dependence, that needs to be called first. Added a
969 parameter depth to type_print() (so it is now like
970 type_print_1). Changed type_print to type_print_at, and
971 made type_print a macro that passes a depth argument of
973 symmisc.c Changed all calls to type_print_1 to calls to
975 Makefile.dist Made it possible to build GDB for a specific set of
976 depend languages. Do this by passing a definition for the macro
977 LANGS to make. LANGS should be a string containing a
978 space-separated list of language names (ie. LANGS="c m2").
979 The default is to build all languages. Note that grammar
980 files must follow the naming convention of <lang>-exp.y.
981 gdb.lang This holds the current value of the LANGS macro. It is
982 examined every time make is called, and is updated if
984 eval.c Added #ifdef _LANG_<lang> to these files.
985 expread.c Still need to add them to dbxread.c and coffread.c.
993 Mon Jun 24 16:33:11 EDT 1991
995 language.[ch] Added the functions hexformat_pre() and
996 hex_to_string_pre(), which take a prefix argument to
997 include in the format string. Thus, hexformat_pre("08") will
998 return "0x08x" (if the working language is language_c).
999 Made hexformat() and hex_to_string() calls to the above
1000 with "" as the prefix argument.
1002 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
1003 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
1004 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
1005 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
1006 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
1007 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
1008 valprint.c, vax-pinsn.c
1010 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
1011 calls to hexformat() and hex_to_string(). Format strings without
1012 the leading "0x" were ignored.
1014 depend Updated to take the above into account.
1017 Tue Jun 25 15:27:18 EDT 1991
1019 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
1020 and type_check_t to keep track of the current state of
1021 range and type checking.
1022 main.c Added the variables range_mode, range_check, type_mode,
1023 and type_check to record the current state of range and
1024 type checking. Added initialization code to main().
1025 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
1026 the above variables.
1029 Tue Jun 25 17:57:08 EDT 1991
1031 dbxread.c process_one_symbol() updates the variable (enum language)
1032 source_lang based on the extension of the filename
1033 contained in the N_SO sybmol that started this symtab.
1034 When end_symtab() is called, the value of source_lang is
1035 put into the language field.
1036 stack.c select_frame() sets working_lang (and possibly type_check
1037 and range_check) to the language field of the symtab
1038 associated with the frame that is selected if working_mode
1039 is language_auto. If working_mode is language_manual, a
1040 warning is printed and working_lang is not set.
1041 language.c Added the function set_type_range(), which sets the value of
1042 type_check and range_check (if their modes call for
1043 automatic setting) based on the current value of
1044 working_lang. A non-zero argument will cause the current
1045 settings to be output.
1048 Wed Jun 26 14:51:40 EDT 1991
1050 eval.c Added range checks on assignment.
1051 m2-exp.y Added the grammar for sets to the language. Currently,
1052 these do not do anything except print an error message.
1054 Wed Jun 26 17:01:04 EDT 1991
1056 m2-exp.y Added the ability for parse_number() to parse negative
1057 numbers. A global flag is set upon encountering a unary
1058 minus. This was done to make, for example, 1 parse as a
1059 CARDINAL, and not as an integer, per Wirth's examples in
1060 Programming in Modula-2 ed.4.
1061 valprint.c Added support for "set radix 2" by then setting
1062 output_format to 't'.
1063 eval.c Implemented range checking on subrange types. Added calls
1064 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
1065 Implemented MIN and MAX for ennumerated types. The
1066 minimum value of an ennumerated type is defined by Wirth
1067 as the first identifier, and the maximum as the last.
1068 m2-exp.y Made octal numbers ending with "B" be characters and those
1069 ending with "C" be numbers, per Wirth's book. (p. 34)
1071 Thu Jun 27 14:11:52 EDT 1991
1073 stack.c select_frame() now only sets working_lang, it does not
1074 notify the user. If working_mode is language_manual, then
1075 a warning is issued once.
1076 main.c At the end of each call to execute_command(), working_lang
1077 is checked against the local static (enum language)
1078 current. If they differ and working_mode is
1079 language_auto, the new settings of language, type and
1080 range checking are printed out.
1081 stack.c Modified frame_info() to include the language of the
1082 current frame in the output of "info frame".
1083 language.[ch] Added the function language_str() which returns the name
1084 of the current language.
1086 Fri Jun 28 15:33:14 EDT 1991
1088 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
1089 the language. INCL and DECL currently cause an error,
1090 since sets are not implemented yet. INC and DEC are
1091 implemented as PREINCREMENT/PREDECREMENT with one
1092 argument, and as ASSIGN_MODIFY with two arguments.
1093 eval.c Added type checking to the above cases.
1094 value.h Added not_lval_constant to the lval_type ennumerated type.
1095 not_lval_constant means that the value is a constant
1096 value; that is 3 or 'a' or TRUE, not as in a constant
1097 identifier. This is used to help coerce numbers such as 3
1098 to either signed or unsigned numbers.
1099 valops.c Added the function value_coerce_constants() which coerces
1100 constant integers as following: if one is a constant and
1101 the other is not, the constant's type is set to the type
1102 of the other argument. If both are constants and one is
1103 signed, the other is converted to a signed constant.
1105 Sat Jun 29 17:26:29 EDT 1991
1107 valarith.c Added a better range checker. It now checks range
1108 (successfully) on integral operations [+-] (signed and
1109 unsigned) for any C sized type. Still does not work well
1110 for multiplication.)
1111 int_in_size() returns an integer that is coerced to fit into
1112 specified number of bytes.
1114 Mon Jul 1 13:04:14 EDT 1991
1116 language.[ch] Added the function binop_result_type(), which returns the
1117 builtin (struct type *) type that would be the result of a
1118 binop on the two values V1 and V2.
1120 Wed Jul 3 19:22:53 EDT 1991
1122 source.c Extended source_info() to include the source language in
1123 the output from "info source".
1125 Fri Jul 5 13:48:52 EDT 1991
1127 utils.c Moved the support functions for the GDB set/show commands
1128 dealing with language into language.c.
1129 language.c Added the function language_info(), which displays info
1130 about the current working language, type and range check
1131 settings. Called via the GDB command "info language".
1132 Added an initialization routine _initialize_language(),
1133 that sets defaults for the language, type and range
1134 variables and sets up the new GDB commands.
1135 main.c Language setup moved to language.c.
1138 Mon Jul 8 10:10:22 EDT 1991
1140 valarith.c Debugged the range checker for arithmetic. Still does not
1141 work for multiplication very well.
1143 Mon Jul 8 12:40:37 EDT 1991
1145 language.[ch] Added the function value_true() which returns non-zero if
1146 its argument represents a boolean true value.
1147 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
1148 check the truth of an expression.
1150 Thu Jul 11 12:51:34 EDT 1991
1152 language.[ch] Added the predicate structured_type(), which returns
1153 non-zero if the argument is a structured type.
1154 Added the predicate pointer_type(), which returns non-zero
1155 if the argument is a pointer type.
1156 eval.c Added the ability to do addition and substraction on
1157 pointers and integers. This case simply bypasses the
1160 Thu Jul 11 14:41:42 EDT 1991
1163 Added the symbol N_DEFD (0x4a) which is a definition
1164 module dependency that is used by the GNU Modula-2
1165 compiler and the linker. It is not important to GDB,
1166 except that [dbx|coff|mips]read.c should ignore these
1169 Fri Jul 12 16:07:00 EDT 1991
1171 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
1172 0 in val_print(). Also added statements to the else part
1173 to coerce type (argument to val_print) to a pointer type
1174 if it is an "array of unspecified length".
1175 valops.c Added the function value_m2_string(), which returns a
1176 (value) value which is a constant string, whose type is
1177 (ARRAY [0..n] OF CHAR). The length field of the type
1178 structure is set to zero, so it will be interpreted as an
1179 "array of unspecified length".
1180 stack.c Moved the language/frame mismatch check to
1181 main.c:execute_command().
1182 main.c The working language is recorded each time
1183 execute_command() is executed. If working lang has
1184 changed during its execution, then the new
1185 language/type/range info is printed out for the user. If
1186 the working language does not match the language of the
1187 frame, a warning is issued.
1189 Sat Jul 13 16:16:39 EDT 1991
1191 eval.c Moved all the type-checking stuff for operators to
1192 language.[ch] language.c. This is so we can keep language-specific
1193 stuff (like for what type operators are defined) in
1195 language.[ch] Added the function binop_type_check(), which checks to see
1196 if its two (value) arguments are type-compatible with its
1197 opcode argument. The opcode should represent an operation
1198 involving an operator. Also added the macro function
1199 unop_type_check, which calls binop_type_check with a
1200 NULL second argument.
1201 expprint.c Added Modula-2 operators to the op_print_tab, so info
1202 expression.h break works correctly. Also added "op_string", which
1203 returns the string corresponding to the (enum exp_opcode)
1204 opcode that is its argument.
1207 Sat Jul 13 18:26:18 EDT 1991
1209 coffread.c Added code to record the type of function arguments with
1210 each paricular function. Code is very similar to that
1212 dbxread.c Moved add_param_to_type() to symtab.c
1213 symtab.[ch] Added function add_param_to_type() from dbxread.c
1215 *** NOTE: The above additions have not been tested.
1217 Mon Jul 15 12:50:47 EDT 1991
1219 langauge.[ch] Added the functions type_error and range_error, which work
1220 like error() except if the type/range mode is set to
1221 *_mode_warn, then they do not do a return_to_top_level(),
1222 but merely print a warning.
1223 Also changed [set|show]_[type|range]_command() to support
1224 the new "warn" feature.
1226 Thu Jul 18 17:50:54 EDT 1991
1228 mipsread.c Added code to record the type of function arguments with
1229 each particular function. Code is very similar to that
1232 *** NOTE: The above additions have not been tested.
1234 Fri Jul 19 11:19:10 EDT 1991
1236 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
1237 UMIN_OF_SIZE, which when given a size of a numeric type,
1238 return the maximum and minimum value it can hold. UMAX...
1239 and UMIN... return the result for unsigned types.
1240 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
1241 struct types. They call above macros.
1242 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
1243 avoid a name conlict with the above.
1244 c-exp.y Added range checking on numeric constants in
1245 parse_number() for completeness.
1246 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
1247 return 0 if working_lang is not language_c.
1249 Thu Aug 8 14:17:22 EDT 1991
1253 breakpoint.c Documentation strings of some commands changed to
1254 eliminate the references to the C language where
1257 Tue Aug 13 15:48:03 EDT 1991
1259 m2-exp.y Added qualified identifiers to the grammar. The semantics
1260 are slightly different from those of the GDB operator ::
1262 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
1263 type_exp, where type_exp is any valid type expression.
1265 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
1266 printcmd.c Modified ptype_command() so it actually parses the input
1267 (necessary for type expressions with scope qualifiers).
1268 Added the function ptype_eval() which expects an
1269 expression composed of one OP_TYPE element.
1270 *.[ch] Replaced all occurences of parse_c_expression with
1272 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
1274 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
1276 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
1278 Small fixes from Peter Schauer:
1280 * infrun.c (child_attach): Lint.
1281 * solib.c (find_solib): Handle shared libs version 2.
1283 Small fixes from David Wood:
1285 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
1289 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
1290 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
1292 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
1293 chars_per_line is at maximum (user typed `set width 0'). Fix
1294 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
1296 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
1298 * coredep.c: include ptrace.h where necessary.
1299 * mipsread.c(parse_lines): fix unsigned char problem that was
1300 messing up line numbers on SGI's and possibly other MIPS based
1302 * infrun.c (child_create_inferior): use better test to check
1303 return val from setpgrp().
1304 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
1305 for sgi/irix support.
1307 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
1309 * mipsread.c (parse_symbol): Put non-static procedures
1310 in the global block.
1312 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
1314 Patch together `text_start' and `text_end' for 29K port.
1316 * exec.c (exec_command): If NEED_TEXT_START_END, define the
1317 variables and set them based on the exec file.
1318 * am29k-tdep.c: declare text_start.
1319 * valops.c (call_function_by_hand): declare text_end.
1321 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
1322 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
1323 because machines that do this will also have to know to
1324 set NEED_TEXT_START_END. Besides, it was a redundant way to
1326 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
1327 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
1328 NEED_TEXT_START_END.
1330 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
1332 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
1334 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
1335 Pass MUNCH_DEFINE to munch whenever we run it.
1336 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
1337 format string; use 0x%x instead.
1338 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
1339 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
1340 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
1341 * inflow.c: Handle `short' process group IDs.
1342 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
1343 and check for ptrace errors.
1344 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
1345 (coff_symfile_init): Initialize text_bfd_scnum.
1346 (read_coff_symtab): Use it to find the text [and absolute?] sections.
1347 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
1348 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
1349 Merge target arm case with other "easy" cases. Add target
1350 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
1351 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
1353 * minimon.h, remote-adapt.c, remote-mm.c: Add.
1354 * munch: Cope with RT/PC putting fns in data segment.
1355 Restore ability to override `nm' by specifying MUNCH_NM.
1356 * xconfig/rtbsd, xconfig/ultra3: New host systems.
1357 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
1358 and remote-adapt. Remove encapsulated coff #define's (the
1359 support should go in BFD, and gdb shouldn't know or care).
1360 * tconfig/a29k-kern: Same, but for remote kernel debugging.
1361 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
1362 * tm-29k.h: Update BADMAG (though it should go away).
1363 Allow the register definitions to be overridden in another
1364 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
1365 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
1366 DUMMY_SAVE_GR96, for handling kernel calling conventions
1367 that use GR64+ rather than GR96+.
1368 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
1369 remote debugging of Ultra3 kernel. Includes tm-29k.h and
1370 overrides various things.
1372 * remote-mm.c (mm_attach, mm_wait): Handle attach like
1373 child_attach does, making a clean stop in the newly attached
1375 * remote-eb.c: Lint.
1377 * coffread.c: Make coffread independent of any particular
1378 variant of COFF. Avoid #include-ing any particular one except
1379 internalcoff.h. BFD now passes key values for symbol reading
1380 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
1381 and the symbol masks and shifts); use them.
1382 Remove obsolete end_of_text_addr.
1384 * exec.c: Remove unused include files.
1386 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1388 * Makefile.in (documentation targets): Pass $(M4).
1389 Bugfix from eggert@twinsun.com (Paul Eggert).
1391 * stack.c (down_silently_command): Check for stack existence.
1393 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1395 * Makefile.in (VERSION): Update to 4.0.3.
1397 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1399 * core.c (core_file_command): Print frame at coredump with
1400 its level number, by calling print_stack_frame.
1401 * frame.h: Add selected_frame_level, print_stack_frame.
1402 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
1403 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
1404 Change print_sel_frame and print_selected_frame callers to
1407 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
1408 * symfile.c (free_named_symtabs): Ditto.
1409 * main.c (main): wrap_here needs an arg.
1410 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
1411 (solib_add): Avoid noise.
1412 (solib_create_inferior_hook): Lint.
1413 (sharedlibrary_command): Move dont_repeat to here.
1414 * utils.c (error): Call wrap_here to force buffered output.
1416 Small patches from Peter Schauer:
1418 * coffread.c (start_symtab): Free any existing line_vector before
1420 (read_coff_symtab): Ditto for type_vector.
1422 * source.c (lines_to_list): New variable, replacing function.
1423 (all uses): Use as variable.
1424 (_initialize_source): Add 'set listsize' and 'show listsize'.
1425 * utils.c (lines_to_list): Remove function.
1426 * stack.c (print_frame_info): Use as variable.
1427 * defs.h (lines_to_list): Remove declaration.
1429 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1431 * breakpoint.c (insert_breakpoints): Restore warning about
1432 the program might be running in another process, but only for
1433 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
1434 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
1436 * utils.c (error): if error_pre_print is set, print the string
1438 * main.c (main, print_gnu_advertisement, print_gdb_version):
1439 Reformat legalese so it always prints, but acts as an "I'm here"
1440 message while symbols are being read. If any errors occur,
1441 print a few newlines to set off the message and start it at the
1442 left margin. Remove mention of "help" command, and don't yak
1443 about symbol reading.
1444 (catch_errors): Error string is now printed first in case of
1446 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
1447 suggest the "help" command.
1449 * Makefile.in (VERSION): Set to 4.0.2.
1451 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
1453 * .gdbinit: Remove useless "rr" command. Set complaints
1454 to 1 for people debugging gdb.
1456 * breakpoint.c, remote-vx.c: Reword strings printed by
1457 catch_errors callers.
1459 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
1461 * WHATS.NEW: "history write -> history save". Doc "write on/off".
1462 (Fix from kenc@viewlogic.com.)
1464 Fix some infrastructure to be able to cope with host and target
1465 machines with different sized basic types (ints, ptrs, etc).
1466 (Idea from pierre@la.tce.com (Pierre Willard).)
1468 * values.c (value_from_longest): Rename from value_from_long.
1469 Handle pointer types as well as integers, so that targets with
1470 different pointer sizes from the host can be accomodated.
1471 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
1472 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
1473 uses of value_from_long to value_from_longest.
1474 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
1475 the correct pointer type to value_from_long{est}.
1477 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
1479 * remote-vx.c: Remove obsolete code for calling functions via
1480 vxworks kludge interface (it referenced value_from_long).
1482 * valops.c (value_string): Find malloc with lookup_misc_func, not
1485 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1487 Make writing to files work properly. (Fixes to BFD are also needed.)
1489 * core.c (core_open): Open file ourselves, read or r/w, depending on
1490 write_files. Use bfd_fdopenr.
1491 * gdbcore.h (write_files): New variable.
1492 * exec.c (write_files): Define variable, add set&show for it.
1493 (exec_file_command): Use write_files to open for read or r/write.
1495 Make shared library reading happen automatically. These changes
1496 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
1498 * inferior.h (stop_soon_quietly): Add to exported variables.
1499 * infrun.c (child_create_inferior): call solib hook, if defined.
1500 (child_attach): call solib hook, if defined.
1501 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
1502 (find_solib): Use lookup_misc_func rather than hand-rolled.
1503 (symbol_add_stub): New stub for catch_errors.
1504 (solib_add): Avoid output if !from_tty. Catch errors rather
1505 than just calling symbol_file_add and bombing.
1506 (solib_create_inferior_hook): Interface with the target process
1507 to let it read and alloc shared libs, then figure out what it did.
1509 * core.c (validate_files): Fix typo, soften warning.
1510 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
1512 * utils.c (fputs_demangled): Avoid duplicate printing if
1513 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
1515 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
1516 (Fix from pierre@la.tce.com (Pierre Willard).)
1518 * main.c (catch_errors): Change argument to a char * from an int,
1519 since a char * can point to a struct full of glop, but an int
1520 is not guaranteed to be able to hold a pointer.
1521 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
1522 breakpoint_re_set_one, breakpoint_re_set): Adapt.
1523 * core.c (core_open, solib_add_stub): Adapt.
1524 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
1526 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1528 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
1529 by adding .NOEXPORT target.
1531 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1535 * Makefile.in (VERSION): Roll to 4.0.
1536 (gdb.tar.Z): Make refcard.ps as well, for shipment.
1538 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1540 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
1543 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
1546 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
1548 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
1549 reflect above name change
1551 * WHATS.NEW: correct pointer to refcard.
1553 * doc/gdb.texinfo: update New Features, Installing
1555 * doc/gdbint.texinfo: add short description of configure +template
1557 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1559 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
1561 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
1563 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
1564 tar file, add dependencies for referenced doc files.
1566 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
1568 * coffread.c, symfile.c, stack.c: saberized.
1570 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1572 * doc/refcard.tex: permuted Essential Commands sec
1574 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
1576 set/show symbol-reloading
1577 default set complaints 0
1579 RET-repeat disabled after prompted long displays
1580 processID (attach) interpretation of 2nd GDB cmdline arg
1582 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
1584 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
1585 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
1586 breakpoint.c, main.c: lint.
1588 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1590 Install new configuration scheme for GDB and friends.
1592 * config.sub: Translate ordinary names to three-part names.
1593 * configure: Use three-part names internally.
1594 * configure.in: Translate three-part names to filenames.
1596 * README, WHATS.NEW: Update for gdb-4.0.
1597 * Makefile.in: Roll VERSION to 3.99.
1599 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
1601 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
1602 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
1603 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
1604 to single structures rather than arrays; when passing
1605 their address, use &. This avoids trouble with bdead compilers.
1606 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
1607 instead. This avoids portability headaches.
1608 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
1610 * source.c (open_source_file): Avoid ANSI const bdeath by
1611 skipping declaration and then casting result value.
1612 * tm-hp300bsd.h: Clarify comment.
1613 * utils.c (strstr): Result is const char *; ANSI bdeath.
1614 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
1615 since system include file defines it differently from "defs.h",
1616 though the two are equivalent for our purposes.
1617 * tconfig/hp300bsd: Add m68k-tdep.o.
1619 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1621 * tconfig/sun*4: Remove warnings about system assembler.
1623 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1625 * mcheck.c: Avoid warning about undeclared abort fn.
1626 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
1627 it causes recursive calls to error() when used in cleanups.
1628 To do so requires that we make it a function, so we do.
1629 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
1630 * utils.c (do_cleanups): Remove the current cleanup from the
1631 chain *before* calling it, in case error() is called from it.
1632 The result won't be pretty, but won't be an infinite loop either.
1634 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
1636 * dbxread.c (read_struct_type): Grok anon structs for C++.
1637 (vb_name, vptr_name): Null terminate these strings.
1639 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1641 Minor bug fixes from BSD Net2 gdb:
1643 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
1644 returns 0, there is no previous frame.
1645 * breakpoint.c (commands_command): If !from_tty, don't call
1646 input_from_terminal_p().
1647 * dbxread.c (record_misc_function): Speed up slightly.
1648 (compare_psymbols): Ditto.
1649 * infcmd.c (do_registers_info): Take a second argument to
1650 determine whether to print float registers. "info registers"
1651 does not do so anymore. "info all-registers" does, now.
1652 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
1654 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
1655 * inflow.c (initialize_inflow): Set tflags_ours correctly.
1659 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
1660 executing_breakpoint_commands if we are interrupted by error.
1661 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
1662 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
1663 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
1664 catch_errors() so we can setup the frame regardless of whether
1665 the shared libs work.
1666 * ieee-float.c (double_to_ieee_extended): Get exponent from
1667 right place in little-endian systems. From John Carey.
1669 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1671 * main.c: Remove unused terminating_signals and catch_termination().
1672 (long_options): Terminate with a zero element.
1673 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
1674 (gdb_readline): Make call-compatible with readline.
1675 (init_signals): Improve comments re vfork vs. signal.
1677 * utils.c (prompt_for_continue): Use new gdb_readline().
1678 If we prompt for continuation, we don't let CR repeat the previous
1679 command, once we get back to a prompt. It's too easy to keep
1680 hitting CR, expecting "--more--" prompts, and have some long
1681 command start repeating on you.
1683 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1685 * blockframe.c (frameless_look_for_prologue): Speed up by
1686 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
1687 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
1688 Define two variants, one faster.
1689 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
1690 and return zero, rather than giving an error.
1691 (setup_arbitrary_frame): Initialize the PC in the new frame.
1692 (skip_prologue): Add a second arg saying whether we're just
1693 checking for a frameless function or not.
1695 * core.c (core_open, core_close, core_xfer_memory): Move
1696 section table pointers and bfd* into the target_ops.
1697 (core_open): Allow errors in shared lib reading, etc.
1698 (core_files_info): Describe shared library sections.
1700 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
1701 exec_files_info, set_section_command): Move section table
1702 pointers and bfd* into the target_ops.
1703 (add_to_section_table): Add BFD to section table.
1705 * target.c (target_xfer_memory, target_info): Pass target to
1706 xfer_memory and target_info functions.
1709 * gdbcore.h: Move struct section_table.
1710 * target.h: New home of struct section_table.
1712 * solib.c (solib_add): New argument is the target_ops whose
1713 section list is to be added to, if any. Reallocate the
1714 sections in that target to add any that come from shared libs.
1715 (throughout) so_sections renamed to sections.
1716 (solib_xfer_memory): Deleted.
1717 * tm-sunos.h (SOLIB_ADD): Add target argument.
1718 (SOLIB_XFER_MEMORY): Delete.
1720 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1721 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
1722 from target_ops. It's the same on all targets. Add two section
1723 pointers to target_ops.
1725 * stack.c (find_relative_frame): Dump ancient algorithm for
1726 "down", just use handy "next" pointers.
1727 (frame_command): Don't error if there is no stack; let user
1730 * inflow.c (new_tty_prefork, new_tty): New prefork routine
1731 modifies static state in the parent process; new_tty itself
1732 runs in the child and modifies the child's file descriptors
1733 to match the saved static state.
1734 * infrun.c (child_create_inferior): Call new_tty_prefork,
1737 * infptrace.c (child_xfer_memory): Add ignored target arg.
1738 * remote-eb.c (eb_xfer_inferior_memory): ''
1739 * remote-nindy.c (nindy_xfer_inferior_memory): ''
1740 * remote-vx.c (vx_xfer_memory): ''
1741 * remote.c (remote_xfer_memory): ''. Rename from
1742 remote_xfer_inferior_memory.
1744 * main.c (main): Only try to attach "corefile" argument if
1745 it starts with a digit.
1747 * symfile.c (symbol_reloading): New "set/show" variable.
1748 (symbol_file_add): Shorten message about symbol reading.
1749 (add_symbol_file_command): Merge with add_syms_addr_command,
1750 since this should work on all targets now.
1751 (stop_whining): Default to zero, to shut up complaints
1752 about bad symbol tables on many systems.
1753 (free_named_symtabs): Just exit unless symbol_reloading.
1755 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
1756 and add comment explaining shared library screw.
1758 * source.c: #if defined => #ifdef.
1760 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1762 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
1764 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1766 * doc/rdl-apps.texinfo: provide default readline-appendix finder
1767 (doc/Makefile knows how to make one for local config)
1769 * Makefile.in: use doc/Makefile for doc targets
1771 * doc/Makefile: GDB documentation now has its own Makefile
1772 doc/refcard.tex: renamed from "gdbrc.tex"
1773 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
1774 doc/gdbint.texinfo: add markup in "Cleanups" chapter
1777 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1779 * values.c (baseclass_addr): When reading target memory, use the
1780 length of the basetype, not the upper type. We've only malloc'd
1781 enough space for the basetype, leading to errors in free().
1783 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
1784 ends up as a function specially, since we know the actual type of
1785 the pointed-to address. This (somewhat) fixes display of
1786 expressions that include misc_function_vector names. Try `cond 1
1787 !strcmp("a","b")' then `i b'.
1789 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
1790 The child can be proceeded from inside wait_for_inferior in
1791 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
1792 getting skipped in that case.
1794 * expprint.c (print_subexp): Use filtered output, since the
1795 subroutines we call use it, otherwise the output is horribly
1796 mangled, since output of wrappable stuff comes out late.
1798 * Makefile.in: Bump VERSION to 3.98.1
1800 * infrun.c (child_create_process): Use execlp to find the
1801 shell to exec our target program. This requires some fiddling
1802 with `environ' since there is no execlpe().
1804 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1806 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
1807 Minor rearrangement of refcard permits two new make targets--
1808 gdbrc.dvi DVI output for refcard, using CM fonts
1809 gdbrc.ps PostScript refcard, using PS fonts
1811 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1815 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
1816 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
1818 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1820 * doc/gdb.texinfo: last changes for release.
1821 Minor typo and formatting fixes; incorporated most fixes remaining from
1822 filed mail commenting on earlier drafts.
1824 Added warnings: pipes don't work in run command;
1825 conditions are converse of assertions;
1826 step over fn without debug info goes to next fn;
1827 vars may have "wrong" values near fn entrance, exit
1829 Added example from Kingston on printing repeated nonadjacent values
1831 Added explicit mention that in Emacs gdb mode C-c and C-z are like
1832 shell mode for signals
1834 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
1835 doesn't sound so much like its parent "Stopping and Continuing"; also
1836 moved entries on continue to top of section, so they don't get lost.
1838 Improved installation directions in appendix, added manual formatting
1841 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1843 * configure.in: Remove xm.h and tm.h even if we aren't linking
1844 new ones, so "./configure sun4; ./configure none" does the right
1845 thing. Assume that alldeps.mak and depend are already built in
1846 srcdir, and avoid running "make" (particularly "make depend",
1847 which involves "gcc") from inside configure. Build Makefile
1848 directly rather than building Makefile.conf first.
1849 * configure: Regenerate with above changes.
1850 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
1851 to 3.98. Revise gdb.tar.Z procedure to produce a file
1852 called gdb-$(VERSION).tar.Z but which unpacks into a
1853 directory called "gdb". Move non-source files out of
1854 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
1855 (depend): Don't try to do "gcc expread.y".
1856 (expread.o): Update dependencies by hand.
1858 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1861 Fixed a variety of small typos that prevented info from formatting
1862 cleanly; altered too-long heading for GPL Appendix, as discussed
1863 w/RMS; Changed date on cover to July 91.
1865 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1868 (1) Applied some fixes due to comments from Larry Breed (easier ones
1869 through chapsec 5.2)
1870 (2) Eliminated use of @footnote---had my doubts about it anyways, and
1871 it's broken in latest texinfo
1872 (3) Introduced *some* use of [] for optional arguments, where
1873 explanation is not simpler by listing cmd w arg and cmd w/out arg
1874 separately. Still not using @deffn.
1875 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
1876 couple of headings are too long. Need patches to texinfo or revision
1879 * Partial update to README (which still needs work for this
1880 release!): (1) use of configure corrected for new script,
1881 (2) "make gdb.dvi" and "make gdb.info" mentioned.
1883 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
1885 * symtab.c (lookup_symbol): Don't complain right off about
1886 no debug symbols; use the misc function vector first.
1887 (list_symbols): Use misc function vector to find symbols
1888 that don't have debug info, and print them.
1889 (find_pc_symtab): Temporarily avoid fatal() when psymtab
1890 PC range doesn't match symtab PC range, as it does on the
1891 MIPS because our symtab reading isn't perfect.
1893 * dbxread.c (dbx_symfile_read): Make warning about
1894 "no debug symbols" slightly nicer.
1896 * source.c (select_source_symtab): If "main" symbol exists,
1897 but decode_line_spec can't find line info, don't just return
1898 a zero; try other source symtabs or give an error.
1900 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
1901 their low addresses first, then rip through fixing high addrs.
1903 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
1904 <runene@ifi.uio.no>.
1905 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
1907 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1909 * Minor, mostly mechanical, cleanup of doc subdir for clean
1910 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
1911 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
1913 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
1915 Mostly MIPS and general symbol-reading fixups.
1917 * doc/gdbint.texinfo: Add documentation on symbol-reading
1920 * mipsread.c: Remove kludges around #include "ecoff.h".
1921 Remove redefinitions of a_magic, etc, no longer used.
1922 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
1923 Fix global overview comments to match symfile.c protocol.
1924 (mipscoff_new_init): Eliminate cur_hdr if we have one.
1925 (mipscoff_symfile_read): Eliminate unused code. Avoid
1926 sorting all the symtabs, when all we have read here is psymtabs.
1927 The symtabs are sorted as they are created anyway. Tell
1928 condense_misc_bunches whether we're mainline.
1929 (psymtab_to_symtab_1): Pass filename when recursing, to make
1930 stack trace more informative.
1931 (parse_partial_symbols): Assume cur_hdr as argument.
1932 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
1933 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
1934 the TYPE_NAME of char *, since that's done in symfile.c.
1935 (free_numargs, parse_symbol, add_symbol, add_block,
1936 shrink_linetable): Declare these fns void.
1937 (upgrade_type): Convert tree of if's to switch. Clean up
1938 bogus "off == 0" handling with a complaint. Avoid setting
1939 field bitpos and bitsize of array with lower and upper bounds.
1940 Check specified bitsize of elements against their actual type's
1941 bitsize, and complain if different. Complain about unknown
1943 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
1944 (psymtab_to_symtab_1): Print names of subsidiary files that
1945 are being read in. FIXME, we read far too many files. This code
1946 is not the problem, the problem is in parse_fdr where the psymtabs
1948 (cross_ref): Result should indicate that we used one aux entry
1949 normally, or two if we encountered a "next" entry. This used
1950 to leave the caller pointing at the wrong aux entry.
1951 (add_symbol): If overflowed cur_block, reallocate it larger,
1952 chase all pointers to it, and complain(), rather than clobber memory.
1953 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
1954 (new_field): Only allocate one field initially, not two.
1955 Pull ++ out of macro argument. Simplify.
1956 (_initialize_mipsread): Avoid initialization of importd
1957 global_psymbols and static_psymbols.
1959 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
1960 to properly set pst->symtab; avoid searching for it.
1961 (symfile_fns): Improve comments, add a FIXME.
1962 * dbxread.c: Update comments to reflect symfile protocol.
1963 (read_ofile_symtab, end_symtab): Return the symtab.
1964 (psymtab_to_symtab_1): Set pst->symtab.
1966 * coffread.c (coff_symfile_read): tell condense_misc_bunches
1967 whether we're mainline.
1969 * symfile.h (sym_fns): Remove unused sym_discard member.
1970 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
1972 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
1973 the environment variable is not.
1974 * infcmd.c (finish_command): Use filtered printfs.
1975 * cplus-dem.c: Add struct tags to a few unnamed structs.
1976 * valops.c (value_coerce_array): Improve comments.
1977 * valprint.c (type_print_varspec_suffix): Print array size only
1978 if greater than zero.
1979 * m88k-tdep.c: Shift some lines left by one space, that had
1980 apparently been trashed at some point.
1981 * TODO: More things to do, a few got done.
1983 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1985 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
1986 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
1988 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
1989 * expread.y, findvar.c, symmisc.c: Ditto.
1990 * printcmd.c (address_info): Update printed forms of LOC_
1991 symbols. Elim LOC_EXTERNAL.
1992 (print_frame_args): Keep track of param stack offsets before
1993 re-looking up to find the local register param is kept in.
1995 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
1996 Further integration of mipsread into gdb. Eliminate unused
1997 routines, duplicate declarations. Handle static symbols in
1998 psymtabs as well as external symbols. When reading symtabs,
1999 insert symbols into the correct block (global, static, or a local
2001 (read_mips_symtab, parse_partial_symbols): Don't pass useless
2003 (mipscoff_symfile_read): Don't call select_source_symtab.
2004 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
2005 rather than SYMBOL_VALUE.
2006 (parse_external): Comment clobbering of top_stack.
2007 (parse_partial_symbols): Update comments. Allocate and parse
2008 static symbols as well as external symbols. FIXME, enum values
2009 are not handled in this pass, but should be. Inline new_psymbol.
2010 Use SYMBOL_VALUE_ADDRESS.
2011 (psymtab_to_symtab_1): Read symbols into global static block
2012 by default (until enter some function's local block context).
2013 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
2014 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
2016 * source.c (select_source_symtab): Select a source symtab
2017 from either the symtabs or, failing that, the psymtabs.
2018 (list_command): Update error message.
2019 (forward_search_command, reverse_search_command): Use getc, not
2020 fgetc, for speed. FIXME, add comment about buffers that die if
2021 overrun by long line.
2023 * values.c (unpack_field_as_long, modify_field): Avoid shifting
2024 by an entire word, which is not portable, if we have a 32-bit
2025 field. (Code in dbxread.c already turns such bitfields, if
2026 aligned, into ordinary ints, but fixing this will help for other
2027 symbol formats and for future changes.)
2028 * core.c (core_open): Handle ANSI const brain death.
2029 * utils.c (vprintf): Fix varargs typo.
2031 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
2033 * findvar.c (find_var_value): Handle &function better.
2034 * TODO: Document work needed on &fn and &array.
2035 * printcmd.c (print_address_symbolic): New arg is the prefix
2036 to print if a name is printed.
2037 (print_address_demangle): Honor "set print address" now.
2038 Use new arg above to improve spacing of output.
2039 * valprint.c (val_print): When printing function pointers,
2040 print symbolic form too.
2041 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
2043 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2045 * core.c (memory_error): Reword error msg to mislead less.
2047 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
2049 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
2050 parse_partial_symbols): Use newer BFD internals (external_filehdr
2051 and external_aouthdr), byte-swap the fields that we care about
2052 before using them, and make the file header data local to
2053 read_the_mips_symtab rather than global.
2055 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
2057 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
2058 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
2060 * main.c (command_line_input): Flush stdout and stderr
2061 before every call to readline. This reportedly fixes a bug
2062 that comes up in Sys V running emacs-gdb and/or xxgdb,
2063 when stdin/out are pipes or sockets.
2065 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2067 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
2068 Avoid declaring Makefile dependencies, because GNU Make stupidly
2069 tries to update it if we do.
2071 * coffread.c: Revise for minor changes to bfd internal coff
2074 * configure: If -template= is given a relative path, make it
2075 absolute before recurring in subdirectories.
2077 * configure, configure.in, Makefile.in: Install "configure" script
2078 as replacement for config.gdb.
2079 * config.gdb, Makefile.dist, Makefile.sdir: Remove
2080 * README: Update for configure, mostly. FIXME.
2082 * Add dec3100 as equivalent to littlemips. Indicate in all host &
2083 target config files that they are for the host. When the lines
2084 get copied into the Makefile, this makes it more obvious what's
2087 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2089 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
2090 tabs, which end up in the disassembler output inadvertently.
2092 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
2094 Make it compile cleanly in an ANSI GCC2 environment.
2096 * blockframe.c: <stdio.h>
2097 * cplus-dem.c: free takes a void *, ifdef __STDC__
2098 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
2100 * defs.h (alloca): Avoid doing anything if alloca already def'd.
2101 * stddef.h, stdlib.h: Remove these files.
2102 * symtab.c: Avoid declaring qsort, close.
2103 * symfile.c: Avoid declaring close.
2104 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
2105 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
2107 Assorted other changes.
2108 * dbxread.c: include "libaout.h", not "liba.out.h".
2109 * printcmd.c (print_frame_args): Set recurse properly for
2110 indentation of struct and array parameters.
2111 * valops.c (value_cast): Allow cast to void.
2112 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
2113 single_step() in a target-independent fashion.
2114 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
2115 set up to be ready to continue. This makes us target independent.
2116 * infptrace.c (child_resume): Remove call to single_step; now
2117 can single step a SPARC target of any kind.
2119 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2121 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
2122 docn into separate sections---basically chapters, plus two loose
2123 pieces that can be configured to go in different places. This
2124 allows GNU m4 to preprocess the manual without coredumping.
2126 * Makefile.dist: tell TeX where to find texinfo.
2128 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2130 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
2131 the new target "rdl-apps.texinfo" which captures the Makefile
2132 variable that records where to find the Readline libraries.
2134 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
2136 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
2137 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
2138 * defs.h (const, volatile): Only define if not already defined.
2139 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
2141 * README: Update for release 3.95.
2142 * config.gdb: Don't create readline dir in subdir builds.
2143 * main.c: Include with "..." form for non-system include files,
2144 so "gcc -MM" for "make depend" works.
2145 Include readline files with "...h" rather than <readline/...h>.
2146 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
2148 * coffread.c: Undo minor damage done by Rich Pixley. Use
2149 different internal and external representations of COFF
2150 data structures. Use new BFD routines for swapping them in and
2152 * symfile.c (free_named_symtabs): Avoid freeing file names that
2153 are null or empty. Old i960 tools seem to produce files that
2154 claim to have empty names, causing each successive file read
2155 to blow away the previous one.
2156 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
2157 Move deferred_stores to top of file, but don't separate its
2158 #define's from its variable. Add commentary.
2159 * Makefile.dist: Fix Rich damage; undo "configure" changes in
2160 favor of keeping the (working) config.gdb. Move readline
2163 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
2165 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
2167 * infptrace.c (fetch_registers): no result, since now void.
2168 * tconfig/news: target depends on m68k-tdep too.
2170 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2172 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
2175 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
2176 applied various small fixes due to or inspired by RMS comments
2178 * doc/gdb.texinfo: finished using all RMS comments, save those for
2179 appendices on readline and cmd history (which are in other source
2182 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2184 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
2185 chapter 9; (2) documented 'break' command's menu mode for
2186 overloaded names, in response to hgs problem report C++ p-31
2188 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2190 * doc/gdb.texinfo: (1) better introductory example; (2) more
2191 consistent use of @code, @samp, @file, @kbd throughout; small
2192 cleanups to first three nodes; (3) new "Contributors" node;
2193 (4) Appendix, Renamed Commands; (5) divert specialized startup
2194 instructions to "Targets" chapter for generic manuals, while
2195 leaving them up front for manuals specific to specialized
2196 environments; (6) apply fixes from RMS comments through chapter 4.
2198 * pretex.m4: modify explanatory text slightly (and redefine
2199 "regexp") to keep GNU m4 from complaining. (It still crashes
2200 later, but one step at a time...)
2202 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
2204 * readline/readline.c (update_line): Avoid dereferencing a pointer
2205 before comparing it to its bounds. Saber caught this.
2206 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
2207 and only set PC if tgetstr returned non-null. Saber caught this.
2209 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2211 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
2212 stuff for config manual) here where it counts; updated
2213 to use new subdir structure (gdb/doc/).
2215 * Makefile: generated from above via
2219 * gdbint.texinfo: added instructions on generating gdb.info* files
2220 locally for release. These are ordinary info
2221 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
2222 Makefile)---but due to use of texinfo 2, can't count on makeinfo
2223 to generate these, so we distribute them already formatted.
2225 * gdb.texinfo: included full Info node and menu crud (as generated
2226 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
2228 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
2229 put in comments-for-future gdb.info target (one day makeinfo will
2232 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2234 * gdb.texinfo: Updated to include new or old undocumented
2235 commands, at least the following (perhaps some others I forgot to
2236 record): info f, info float, info path, info program, info s, info
2237 set, info source, info terminal, info types, info user, set/show
2239 Also covered all recent GDB command renames for v4.
2241 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2243 * mipsread.c: Rather than keeping count of how many symtabs
2244 and psymtabs we have, for sorting purposes, count them when
2245 we need to sort. This fixes bug in rereading of symbol tables.
2247 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2249 * infcmd.c: renamed "info path" to "show paths"

2263 * coffread.c, exec.c, infptrace.c, inftarg.c, remote.c, solib.c,
2264 symtab.h, target.c, target.h: Lint.
2265 * core.c: setup and select frame after reading shared libs,
2266 else reading shared libs will clobber them. Lint.
2267 * utils.c (error): Force out any buffered wrap text.
2269 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2271 * remote.c: Remove decls of memory_insert_breakpoint
2272 and memory_remove_breakpoint, no longer used. (Suggestion of
2275 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
2276 to make it easier to interface to "configure"'d libraries.
2278 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
2280 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
2281 aliases for set/show print.

2337 * coffread.c [TDESC]: Move setting of debug_info from
2338 coff_symfile_read to find_linenos and make it work with BFD.
2340 * cplus-dem.c [__STDC__]: Make x{m,re}alloc return void*.
2342 * signame.c: Cast const char* to char* when assigning to sys_siglist.
2344 * utils.c (strsave): Make arg const char* not char*.
2346 * infrun.c (wait_for_inferior) [SHIFT_INSN_REGS]: Use

2367 Mips bringup and general cleanup
2369 * cplus-dem.c: Move CPLUS_MARKER define to after defs.h.
2370 * infptrace.c (PT_WRITE_D, PT_READ_D): Use correct values.
2371 (This still doesn't seem to make MIPS bkpts work.)
2372 * mipsread.c: Remove dup "Reading symbol data..." msg.
2373 (symbol_file_command, add_file_command): Remove, obsol.
2374 * printcmd.c (ptype_command): Say "an enum" rather than "a enum".
2375 Wrap output appropriately.

2377 selected_frame rather than target_has_stack or coredumping.
2378 * valprint.c (type_print_varspec_suffix): Wrap "ptype" output of
2379 enums appropriately.
2381 Wed May 1 14:10:22 1991 Jim Kingdon (kingdon at cygint.cygnus.com)

2390 can have both ints and enum type_pieces in it.
2391 ({push,pop}_type_int): New functions.
2393 Tue Apr 30 13:18:58 1991 Jim Kingdon (kingdon at cygint.cygnus.com)

2405 symtab.c, cplus-dem.c, value.h, expread.y, valprint.c,
2406 copying.awk, solib.c, inflow.c, symmisc.c
2407 : Lint. Use read_memory not read_memory_integer on CORE_ADDR's.
2408 Use {value_as,unpack}_pointer (added to values.c)
2409 not {value_as,unpack}_long on CORE_ADDR's.
2410 Use longest_to_int (added to defs.h) instead of cast to int.
2411 Remove from_tty arg to mod_path.
2412 Put symfile_bfd in {coff,dbx}read.c not symfile.h.
2413 Use OP_NULL instead of 0 where dummy enum exp_opcode needed.

2898 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
2899 for printing the float info is host-dependent, not
2900 target-dependent. FIXME.
2901 * i386-pinsn.c: Move #includes to top, remove useless ones.
2902 * i386-tdep.c: Don't bother including <.../reg.h> since we
2903 don't use it (and it doesn't exist on host systems).
2905 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
2906 Convert negative numbers properly.
2907 (ieee_test): Make numbers really random; fix format arg.
2909 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
2910 * core.c (core_detach): Unpush core_ops, which might not be on
2911 top. We used to just pop the top, which broke things. Don't
2912 need dont_repeat() any more.
2913 (core_file_command): Psst! Don't repeat it.
2914 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
2915 * expprint.c (print_subexp): Avoid switch fallthru on
2916 BINOP_ASSIGN_MODIFY, so we can print += and such.
2917 * frame.h: Fix typo.
2918 * inflow.c (kill_command): After killing inferior, print our
2919 current frame in the core file, if we have one.
2920 (generic_mourn_inferior): When inferior dies, either select
2921 the current frame (in the new target, e.g. core file), or
2922 set both the current and selected frames to NULL.
2924 Changes from Peter Schauer.
2926 * infptrace.c: Avoid <sys/ptrace.h> on USG.
2928 * Make all file names fit in 14 characters (sigh and damn!):
2929 mv hp300hpux-xdep.c hp300ux-xdep.c

2937 mv remote-sa.m68k.shar rem-m68k.shar
2938 mv remote-multi.shar rem-multi.shar
2939 * Makefile.dist, README, config.gdb, convex-pinsn.c,
2940 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
2941 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
2944 * command.c (user_info_1, user_info): New command for listing
2945 the user-defined commands.
2947 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
2949 * dbxread.c (really_free_pendings): Clear file_symbols
2950 and global_symbols after freeing them; otherwise, running
2951 this function twice (if it appears twice on the cleanup
2952 chain), we try to free things twice.
2954 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
2955 based on text_addr (the address of text in core), not on addr (the
2956 offset between text in the .o file and in core). This change
2957 is from Peter Schauer.
2959 * main.c: Define ALL_CLEANUPS as a cast of zero.
2960 (return_to_top_level): Use it.
2961 (main): Do all cleanups after each command run as part
2962 of the gdb startup sequence. Also do all cleanups before
2963 entering the command loop, and every time we exit the command
2964 loop and reenter. Before, the cleanups from the startup sequence
2965 were being left undone until the first error!
2966 (command_loop): Rename do_nothing cleanup to command_loop_marker
2967 so we can see it easily when examining the cleanup chain.
2968 (init_signals): Add another do_nothing for signal handling.
2969 (quit_command): Only try to kill target if it has execution.
2970 Problems in the target stack got us into a state where
2971 inferior_pid was nonzero but none of the targets had execution.
2972 In this state you couldn't exit gdb.
2974 * dbxread.c: Two changes from Peter Schauer.
2975 (echo_command): Fflush output after an echo command.
2976 (show_history): Pass all args to cmd_show_list.
2978 * utils.c (init_malloc): Call mtrace to turn on tracing
2979 if the environment variable MALLOC_TRACE is set to a file name.
2980 * mtrace.c: Add source file which provides a log of every malloc,
2981 free, and realloc to a trace file.
2982 * mtrace.awk: Add source file which analyzes the trace file.
2983 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
2984 (VERSION): Roll to 3.94.3.
2986 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
2987 (check_duplicates): Don't bother with watchpoints.
2988 (set_raw_breakpoint): Comment about danger of this routine.
2989 (watch_command): Parse and eval all args before calling
2992 * solib.c (find_solib): Avoid error in referencing memory to
2993 see if any more shared libraries have been added. This is
2994 particularly useful if the target has terminated. Bug reported
2997 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
2998 in bringing up 3.94.2 on the Sun-3.
3000 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
3001 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
3002 expression (in scope) before reenabling watchpoint.
3003 * signame.c (init_sigs): Add missing declaration of i, fix
3004 sys_siglist declaration.
3005 * source.c (list_command): Fixed range computation to use
3007 * stack.c (backtrace_command): Do not allow command if target has
3008 no stack, print informative error message.
3009 * target.c (target_command): Do not write into command line
3010 because this fails if the target command is used in a user defined
3011 command. [This change was enhanced by gnu to support any-
3012 unique-prefix matching on target names.]
3013 * valops.c (value_struct_elt): Avoid infinite loop on an
3014 erroneous attempt to print the member of function (try p main.p).
3016 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3018 * expread.y (name_no_typename): Avoid reduce/reduce errors
3019 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
3020 Since the GDB parser really doesn't use name_no_typename in a
3021 name-only context, the parser can't tell the diff between
3022 names and numbers here. Avoid allowing a name_no_typename
3023 to be a NAME_OR_*INT to resolve the conflict.
3025 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3027 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
3029 * valprint.c (val_print_fields): bitfield printing didn't handle
3030 byte order. Indirect through a few more fns to cope.
3032 * values.c (modify_field): also cope with byte order.
3034 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
3036 Cleanup for release 3.94.2:
3038 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
3039 include files. Roll version to 3.94.2.
3041 * coffread.c (init_stringtab): Read length into unsigned char
3042 array before swapping; don't assume 32-bit longs.
3044 * target.c (target_info): Don't bother with get_sym_file, just use
3045 the symfile global variable.
3046 * symtab.h, symfile.c (get_sym_file): Delete it.
3048 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
3049 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
3050 (read_type): Replace one more error() with complain().
3052 * mipsread.c (parse_partial_symbols): Replace printf with complain.
3054 * i960-tdep.c: Fix copyright attribution.
3056 * config.gdb: Quote all backquotes in doublequotes. You can
3057 quote me on that. BSD 4.4 shell found this one.
3059 * infptrace.c (throughout): The third argument to ptrace is an
3062 * infrun.c (wait_for_inferior): When program has terminated, we
3063 have to call target_terminal_ours before we pop that target off
3064 the stack (e.g. before a call to target_kill or
3065 target_mourn_inferior). This fixes problem where a program
3066 terminates, then GDB stops for (tty output) and you have to type
3067 "fg" to the shell to resume it. FIXME: This code for what to
3068 do after termination really should be in normal_stop instead.
3070 * gdbcore.h (read_memory_check): Change declaration; it changed
3073 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
3074 4.4 prereleases, this avoids a bug in their sgtty compatability
3076 * remote.c: Use terminal.h rather than hand-rolling the same.
3078 * signame.c, signame.h (psignal): Arg is unsigned, not int.
3079 * utils.c (strsave, strstr): Fix arg types.
3080 * valprint.c (val_print): lint
3082 MIPS symbol table support from Per Bothner:
3084 * symfile.c (symtab_fns): Remove initializer table that needs to
3085 be hacked for each new symbol file format supported.
3086 (add_symtab_fns): New function, chains symbol table
3087 handlers into the global list.
3088 (symfile_init): Search this list.
3089 * symfile.h: Add next pointer, declare add_symtab_fns.
3090 * coffread.c (_initialize_coffread): Call add_symtab_fns.
3091 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
3093 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
3094 symbol *). Thus, we no longer need the hack to trash
3095 pst->filename. Good, since that hack confused code in symfile.c!
3097 (reorder_symtabs, destroy_all_symtabs): Removed static
3098 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
3099 Instead, the latter now uses a temporary array (stack-allocated
3100 from an obstack, and then freed).
3102 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
3103 haven't been set in the outermost stBlock of a procedure. This was
3104 a problem with f77 binaries on Ultrix 4.?.
3106 (new_symtab, new_symbol, new_type): Continue changing code to use
3107 obstacks more and otherwise conform to dbxread internal style.
3108 Made the free_code of symtabs be free_linetable (as in dbxread)
3109 instead of free_contents. This implies memory leaks when reading
3110 a new symbol table, until the conversion is finished. Did change
3111 (struct symbol) and (struct type) to be allocated on the
3112 symbol_obstack. Blocks and blockvectors are among the things
3115 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
3116 tested much, but it solved one problem (reported by Meissner), and
3117 cleans up some other things. The problem happened when an
3118 included file contains actual code (functions) and not just
3119 definitions. The mips coff is a little inconvenient there, since
3120 it may cause a procedure to be mapped to the wrong psymtab.
3122 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
3123 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
3124 this will need work for the new core paradigm.
3126 Opcode patches from the net:
3128 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
3129 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
3130 missing altogether - they are added here. From Bruce Bauman.
3131 * mips-opcode.h: The low mask for C0 instructions was too small.
3132 From Garrett Lau. I modified the fix to check the entire 32-bit
3135 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
3138 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3140 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
3142 * dbxread.c (read_type): Pointer subtraction (value_sub in
3143 valarith.c) sometimes failed because the types of the
3144 pointers being subtracted were not identical.
3145 These differed because dbxread.c was allocating pointer types
3146 using dbx_alloc_type+smash_to_pointer_type instead of
3147 lookup_pointer_type. I failed to find a justification for the
3148 former, so I changed it to use the latter. Similarly, I
3149 replaced smash_to_function_type by lookup_function_type,
3150 and smash_to_reference_type by lookup_reference_type.
3152 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
3153 _initialize_mipsread): corresponding changes.
3155 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
3157 * source.c (mod_path): Do tilde_expand on each component of the path,
3158 rather than on the (list of) paths as a whole.
3159 (print_source_lines): Set first_line_listed in addition to
3160 current_source_symtab and current_source_line. If the source was
3161 not findable, after a "dir" command to fix the problem,
3162 a "list" would get the wrong lines.
3164 While I was there... (gnu):
3166 * dbxread.c (read_type): Change error to complaint.
3168 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3170 First attempt at detailed understanding of symbol table memory alloc.
3172 * dbxread.c (dbx_symfile_read): Free our string table if we
3173 aren't the mainline. Free the "info" struct since we're done with
3175 (init_psymbol_list): Free any previously allocated psymbol lists.
3176 (): FIXME: Should realloc-down the psymbol lists when done reading
3177 the main symbol file?
3179 * symmisc.c (free_symtab): Free fullname field too.
3181 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
3182 (REGISTER_ADDR): Make result type unsigned int.
3184 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
3185 define REGEX must also define REGEX1 (its dependency).
3187 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
3189 * tconfig/i960: No longer works, points you at vxworks960 or
3192 * xgdb.c, XGDB-README: Remove file. Users can get the much
3194 * Makefile.dist: Remove all trace of xgdb.
3196 * breakpoint.c (breakpoint_1): Pass demangle arg to
3197 print_address_symbolic.
3198 (clear_breakpoints): Remove unused function.
3199 (breakpoint_re_set_one): Guts of breakpoint_re_set.
3200 (breakpoint_re_set): Use catch_errors to do them all anyway.
3202 * gdb-int.texinfo (Host versus Target): Add section on what is
3203 a "host" feature versus what is a "target" feature.
3205 * infcmd.c (path_command, path_info): Handle the PATH variable
3206 (object search path) as conveniently as the source search path.
3207 * environ.c (set_in_environ): Set some vars in GDB's environment,
3208 in addition to the child's. PATH, G960BASE, G960BIN for starters.
3209 * source.c (mod_path): New function, from guts of
3210 directory_command, modifies a path. Used by path_command.
3211 (directory_command): Call it.
3212 * defs.h (strsave): Declare.
3214 * utils.c (sevenbit_strings): Add new printing option.
3215 (printchar): Use it.
3216 (strsave): Provide this handy helper routine.
3217 (set_width_command): Rename set_screen_width_command.
3218 (_initialize_utils): "set screen-width" => "set width";
3219 "set screen-height" => "set height"; add sevenbit-strings.
3221 * infcmd.c (do_registers_info): Print floating point registers
3222 in raw hex as well as float format, regardless of whether it is
3223 a "virtual" convertible register.
3224 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
3225 regs as a double, just in case it's being used that way.
3226 * values.c (unpack_long): Comment on array/function coercion.
3227 (unpack_double): Argument is in target byte order now. For
3228 integer arguments, just call unpack_long and float the result.
3229 * m68k-tdep.c: include defs.h for "const" handling.
3230 * remote-nindy.c: Use ieee-float stuff.
3231 (nindy_fetch_registers): Unpack double regs to host double, then
3233 (nindy_store_registers): Pack extendeds to host double, flip
3234 around by misusing unpack_double, send as target double.
3236 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
3237 zero, as when stopped at the first instruction of a process.
3239 * blockframe.c: Fix filename in comment (param.h => tm.h).
3240 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
3241 * tm-68k.h: Fix typos.
3243 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
3245 Changes from a bringup on the DEC Vax under Ultrix 4.0.
3247 * coredep.c (fetch_core_registers): Pass end-address of register
3248 section to register_addr as expected. Don't call supply_register
3249 if we'd just pass it garbage.
3251 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
3253 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
3255 * target.c (push_target, target_info): Cast enums to int for < or
3258 * stack.c (print_frame_info): Identify source file & line
3259 even if we can't print it.
3261 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
3263 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
3265 Clean up IEEE floating point support.
3267 * ieee-float.h: New file.
3268 * ieee-float.c: Write real routines to convert between host
3269 doubles and various target IEEE extendeds.
3270 * m68k-xdep.c: Eliminate assembler code for extended floats.
3271 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
3272 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
3273 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
3274 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
3275 double_to_ieee_extended.
3276 * i960-tdep.c: Define ext_format_i960.
3277 * m68k-tdep.c: Define ext_format_68881.
3278 * sparc-tdep.c: Define ext_format_sparc, though unused.
3279 * Makefile.dist (HFILES): Add ieee-float.h.
3280 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
3283 Obsolete the "coffstrip" program in favor of using BFD's strip.
3285 * nindy-share/coffstrip.c: Remove file.
3286 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
3287 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
3288 * tconfig/nindy960: Remove reference to coffstrip.o.
3290 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
3292 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3294 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
3295 * dbxread.c: Remove static symfile_bfd.
3296 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
3298 * inftarg.c (child_detach): Pop the child_ops vector if the
3299 detach is successful.
3300 * remote-nindy.c (nindy_create_inferior): Don't push a new
3301 nindy_ops since nindy uses the same one for execution and memory
3303 * core.c (core_ops): Use child_attach and child_create_inferior
3304 rather than default attach and create_inferior functions.
3306 Handle floating point registers in core files.
3308 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
3309 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
3310 This version untested since BFD doesn't yet support sun3 core
3312 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
3313 conventions. Fix comments and style. This version has not
3314 been compiled yet, since we have no HP inhouse.
3315 * core.c (get_core_registers): Look for two sections, ".reg"
3316 and ".reg2", and pass both to fetch_core_registers sequentially.
3318 Revise directory path yet again.
3320 * source.c (forget_cached_source_info): Not static any more.
3321 (init_source_path): New default source path is "$cdir:$cwd".
3322 (dir_command): Handle variable arguments ($cdir, $cwd).
3323 (source_info): Print "Compilation directory" rather than
3324 "Originally compiled in" to remind people of $cdir.
3325 (openp): If the path contains $cwd, use current directory.
3326 (open_source_file): If compilation directory is known, replace
3327 first $cdir in path with the compilation directory.
3328 (print_source_lines): Even if we can't print the lines, set the
3329 current symtab and line for future commands like "info source" or
3330 "breakpoint". Also, error message now contains the file name,
3331 line number, and file access error message.
3332 (_initialize_source): Fix help text to describe changes.
3333 * main.c (cd_command): Forget cached source info when we chdir.
3334 * utils.c (strstr): Add simple implementation.
3336 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
3338 * coffread.c (read_one_sym, init_linetable, init_stringtab):
3339 Byte-swap COFF symbol tables if necessary when reading them in.
3340 Use complain() to replace error message in one spot. Needs
3341 corresponding change in bfd/coff-code.h to make some symbol
3342 swapping routines non-static.
3344 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3346 Merge changes from Eirik Fuller, for UTek.
3348 * defs.h (errno): Add declaration.
3349 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
3350 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
3351 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
3352 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
3353 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
3354 declarations of errno.
3356 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
3358 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
3359 <rpc/rpc.h> and <rpc/types.h>.
3361 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
3363 * i960-tdep.c (examine_prologue): Add new argument limit,
3364 which stops the scan at the end of the prologue, or at the PC.
3365 This fixes a problem where it walks down into the code for the
3366 user's statements if that code looks like function prologues.
3367 Mark Fox and I have been bouncing this code back and forth, making
3368 small changes to it. Callers changed to match.
3370 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
3372 Cleanup for gdb-3.94 release final:
3374 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
3375 the .c files from vx-share and nindy-share, from the various
3376 macros, since they are not found via ALLDEPFILES.
3377 (SFILES): Add tm-i960.h.
3378 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
3379 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
3381 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
3382 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
3384 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
3386 * am29k-tdep.c: Add contribution line.
3387 (examine_prologue): Cache information about function prologues in
3388 the misc-function-vector to avoid lots of references over the
3389 serial line while examining instructions.
3391 * core.c (core_close): New function made from cleanup_core.
3393 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
3394 remote-vx.c, remote.c, target.c, target.h,
3395 Update target_ops vector to add attach, close, and load entries.
3396 Use add_syms_addr_command, not add_file_addr_command, for
3397 add_file. Break out close routine from existing code.
3399 * dbxread.c (really_free_pendings): Don't free pending_blocks;
3400 they are in an obstack.
3401 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
3403 (define_symbol): Add symbol type parameter; change callers;
3404 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
3405 it to influence the symbol class on the i960.
3406 (define_symbol): Swap LOC_CONST's into target byte order.
3408 * exec.c (exec_close): New function.
3409 (exec_file_command): Call it.
3411 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
3412 Fix byte order of frame pointer.
3413 (read_var_value): Result of 0 if var's value can't be found,
3414 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
3415 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
3416 (locate_var_value): Use read_var_value and use its lazy address
3417 as the location of the var's value. Lint.
3419 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
3422 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
3423 obsolete Intel versions in favor of vxgdb versions.
3424 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
3425 code dealing with byte order of values, which Intel did in host byte
3426 order rather than gdb-4's target byte order.
3427 (i960_frame_chain_valid): Move to nindy-tdep.c.
3428 (examine_prologue, skip_prologue, frame_find_saved_regs,
3429 frame_args_address, leafproc_return, saved_pc_after_call,
3430 pop_frame): Add vxgdb versions from Mark Fox.
3431 (examine_prologue, frame_struct_result_address): Add code
3432 to deal with the saved value of G13 (struct return address
3434 (frame_args_address): Modify Mark's version to prefer the
3435 saved value over the current value in the topmost frame.
3436 Cache result in the frame info to avoid performance hair in
3438 (print_fault): Add gdb960 code for printing faults.
3439 (_initialize_i960): Actually call check_host.
3441 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
3442 add stub routines. FIXME, these currently just return zero!
3444 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
3445 (attach_command): Call target_attach, not target_open, now.
3447 * infrun.c (normal_stop): Make global, not static, for vx_attach.
3448 (child_attach): Rename from child_open.
3449 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
3450 don't confuse it with a zero step_resume_break_address.
3452 * inftarg.c (child_detach): Eliminate inferior_pid test.
3453 (child_files_info): Clean up message a bit.
3454 (child_ops): Use child_attach, not child_open, to attach.
3456 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
3457 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
3458 findvar.c to here, since it depends on the contents of the
3459 shadow_contents of breakpoints, but keep if #if 0 since it is
3462 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
3465 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
3466 (ptype_command, display_command): Eliminate have_inferior_p and
3467 have_core_file_p in favor of target_has_stack or
3468 target_has_execution.
3469 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
3470 code for actually finding the values of arguments, though we still
3471 keep track of the maximum stack offset for use in printing unnamed
3472 arguments. Handle missing FRAME_ARGS_ADDRESS.
3474 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
3475 (struct nindy_regs): Define registers passed to/from nindy.
3476 (nindy_fetch_registers, nindy_store-registers): Translate between
3477 nindy and GDB formats for the registers.
3478 (dcache_init): Statically allocate the cache, since it was being
3479 allocated by a malloc that was never freed anyway.
3480 (nindy_create_inferior): Error, not core dump, if no exec file.
3481 (nindy_before_main_loop): Use target_load, not target_add_file.
3483 * remote-vx.c (net_load): Specify large timeout for load
3484 requests. Allow user to break out with INTERRUPT.
3485 (net_break): Remove useless code, clean up. Change callers.
3486 (parse-args, skip_white_space, find_white_space): Clean up arg
3487 parsing to cope with quoted strings.
3488 (net_wait, net_quit): Never call error, just return status.
3489 (vx_read_register, vx_write_register): Cleanup status checking.
3490 #ifdef the code based on which CPU we are using (960 or 68k),
3491 FIXME, this should be completely general but it isn't yet.
3492 (vx_xfer_memory, vx_resume): Cleanup status checking.
3493 (vx_run_files_info): Improve message.
3494 (vx_load_command): Renamed from vx_add_file_command. Allow load
3496 (net_ptrace): Remove unused routine.
3497 (vx_wait): Adopt code from vxgdb960 to cope with broken
3498 connections to target machine and prompt to disconnect. Remove
3499 debug printouts. Map some EVENT_'s to SIGnals.
3500 (add_symbol_stub, vx_open): Print names of object files we found,
3501 and "ok" if we read their symbols OK. Clarify output in general.
3502 (vx_attach, vx_detach, vx_kill): Add these commands.
3503 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
3504 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
3505 "info files" output, and create_inferior, since we already have
3508 * stack.c (frame_info): Replace Frame_unknown with 0.
3509 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
3510 (return_command): Pop until the PC matches as well as the FP,
3511 so it works even if the FP is shared with another function,
3512 as in "frameless" or "leaf" procedures.
3514 * symfile.c (load_command): renamed from add_file_target_command.
3515 (add_syms_addr_command): renamed from add_file_addr_command.
3516 (add_syms_command): Stub to call target_add_syms.
3517 (_initialize_symfile): Change command names and descriptions,
3518 add-file => add-syms, and load from alias to its own command.
3520 * target.c (kill_or_be_killed, maybe_kill_then_attach,
3521 maybe_kill_then_create_inferior): Default for attempts to start
3522 a process, if one is already running, is to ask about killing
3523 it and retry if yes.
3524 (upstack_create_inferior): #if-0 it, strata obsolete it.
3525 (push_target, unpush_target, pop_target): to_close() a target
3526 before unstacking it.
3527 (target_info): Renamed from target_files_info.
3528 (_initialize_targets): Rename "i files" as "i target", accessible
3531 * target.h: Improve comments about the target_ vectored routines.
3533 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
3534 Convert commenting style to standard GNU style.
3535 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
3536 (SKIP_PROLOGUE): No longer a no-op.
3537 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
3538 (*_REGNUM): Sort register numbers.
3539 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
3540 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
3541 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
3542 are now 10 byte extendeds, not 8 byte doubles.
3543 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
3544 for nindy versus vxworks targets. FIXME, this should possibly go
3545 in the target vector.
3546 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
3547 frame_saved_regs and arg pointer with each frame.
3548 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
3549 (FRAME_ARGS_ADDRESS): Use cached result.
3550 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
3551 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
3552 (PRINT_RAMDON_SIGNAL): Call print_fault.
3553 (POP_FRAME): Now works.
3555 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
3556 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
3557 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
3558 (ADDITIONAL_OPTION_HANDLER): use target_load, not
3561 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
3562 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
3564 * valarith.c (value_subscripted_rvalue): Avoid handling
3565 floats and doubles specially; it gave alignment errors. Lint.
3567 * valops.c (value_of_variable, value_of_this): Error if unknown
3570 * valprint.c (print_floating): Bcopy rather than pointer-deref,
3571 to avoid alignment problems.
3572 (value_print): Handle unknown value address.
3573 (cplus_val_print): Two args are ignored; remove them. Change caller.
3574 (val_print): Use unpack_long rather than pointer-deref.
3577 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
3578 to avoid alignment problems.
3579 (value_being_returned): Error if return value unknown.
3580 (set_return_value): Add bogosity warning, FIXME. *
3582 * TODO: A woman's work is never done.
3584 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
3585 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
3586 Add ieee-float.o to OBS.
3587 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
3588 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
3589 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
3591 Changes to generalize the VxWorks RPC protocol slightly, to handle
3592 i960 as well as 68000.
3594 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
3595 * vx-share/reg.h: Produce i960 regs #ifdef I80960
3596 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
3597 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
3598 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
3599 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
3600 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
3601 so they will move in target byte order rather than network
3602 byte order (happens to be the same).
3604 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
3606 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
3608 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
3611 Add contribution lines to various files, showing where they
3614 * breakpoint.c (break_insn, check_break_insn_size,
3615 read_memory_nobpt): Remove to mem-break.c.
3617 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
3620 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
3621 entry has bad register number. This change is not
3622 tested in this release, FIXME.
3624 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
3627 * value.h: Force value's contents field to be aligned to hold
3628 at least a double or a long long (if supported). This avoids
3629 doing bcopy's in and out of the contents field.
3631 (step_1): Avoid coredump under obscure circumstances when we
3634 * symtab.h (misc_info): Add field to misc function vector for
3635 any kind of cached information the target code desires. AMD
3636 29000 uses this to avoid repeating examine_function_prologue's.
3638 * coffread.c: Lint. Remove static symfile, read_section_header.
3639 core.c (have_core_file_p): Lint: remove.
3640 expprint.c (print_subexp): Lint.
3641 infptrace.c, valops.c, valprint.c: lint.
3643 Roll in changes from vxgdb-5.0.1:
3645 * symtab.h: Comment byte order of each address class. Add
3646 LOC_LOCAL_ARG for frame-relative args (960).
3647 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
3648 symtab.c, symmisc.c: ditto.
3650 * infrun.c (init_wait_for_inferior): Clear stop_signal.
3652 * remote.c (remote_resume): Error if resume with a signal.
3654 * symfile.c (prim_record_misc_function): Clear misc_info.
3655 (fill_in_vptr_fieldno): Check stub type of arg.
3657 * valops.c (value_cast): Avoid looking up names of types whose
3658 name we don't know, to prevent coredump. Sun CC produces typedef
3659 rtx and the name of *rtx is zero...
3661 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3663 Roll in changes from final AMD 29000 port (Tiemann).
3665 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
3666 for ../include/a.out.encap.h. This might not work now that BFD
3667 is separately compiled. Instead, BFD support for encap will have
3668 to translate machine type 29k into the right COFF_MAGIC.
3670 * infcmd.c: Remove references to inferior_pid that aren't used
3671 in actual ptrace calls; use target_has_execution, etc.
3672 (have_inferior_p): Remove function.
3673 (program_info): Print target info rather than "process number";
3674 avoid gratuitous messages unless from_tty.
3675 (run_stack_dummy, finish_command): Set proceed_to_finish.
3676 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
3677 main.c: Lint. Lose have_inferior_p().
3678 inferior.h (have_inferior_p): Remove, lint.
3679 (proceed_to_finish): Add flag to ask that all regs be saved
3680 by normal_stop, for the few commands that need it, speeding up
3681 serial I/O. Add comments to stop_registers.
3683 * remote-eb.c: Remove newline from breakpoint message we grep
3684 for. Never time out when running the user program.
3688 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3690 Roll in changes from vxgdb-5.0.1:
3692 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
3693 symbol in its raw form, we are processing an unlinked ".o" file.
3694 See if the target environment has assigned it an address, using
3695 target_lookup_symbol (VxWorks does), and enter it into the symtab
3698 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
3699 68k versions for a simpler version that assumes zero FP at bottom.
3700 Fixes bug of truncated stack reports.
3702 * target.h (target_lookup_symbol): Define this routine's args
3703 and result, finally.
3705 * target.c (nosymbol): Default routine for target_lookup_symbol.
3706 (target_default): Default lookup_symbol and call_function too.
3707 (files_info): Only print has_all_memory warning if a non-dummy
3710 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
3711 vx_convert_from_virtual): If target does not have floating point,
3712 zero register "values", and avoid doing cross-net conversions.
3713 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
3714 (vx_open): Rearrange code that attaches to target and reads
3715 symbols for all loaded modules, to work if some of the modules
3716 are not accessible. Add symbol_stub() and add_symbol_stub()
3717 as callbacks from catch_errors(). Allow connect attempt to be
3718 interrupted painlessly with ^C (FIXME, there are still some bugs
3719 if the interrupt happens during symbol reading.). Print
3720 final message with puts_filtered, since symbol messages are
3725 * main.c (catch_errors): Only print errstring if non-null.
3726 (command_loop): Avoid an ioctl per command to test ISATTY.
3728 * remote-vx.c (net_load): make static; avoid sophomoric msg.
3729 (vx_xfer_memory): Return correct result!
3730 (vx_files_info): Indicate whether target has float or not.
3731 (vx_lookup_symbol): Complain, not error, if target gone.
3732 (vx_open): Print "Connected" msg before disabling immediate-quit.
3733 [FIXME: lookup_symbol and vx_open changes need testing.]
3735 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
3736 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
3737 contributor lines and update copyrights to 1991.
3739 Changes from an attempted H-PUX host port:
3741 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
3742 defines PT_ATTACH and PT_DETACH but not PT_KILL.
3743 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
3744 * remote-vx.c: include <sys/time.h> for HPUX.
3745 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
3746 "core_file_command" routine to BFD regime. May not work yet.
3748 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
3750 * xgdb.c: Replace X10 version with some VJ version.
3751 (FIXME: Its copyright assignment is not on record.)
3752 * xgdb.c: Update include files to X11R4 (Xaw crud).
3753 (xgdb_display_source, create_text_widget): fix call to
3754 get_filename_and_charpos. Rewack source window stuff for X11R4
3755 (gleaned from include files, and "nm's" of binary libraries, since
3756 I had no doc available).
3757 (append_selection, append_selection_word): Disable with FIXME
3758 since R4 changed interface here.
3759 (create_buttons): Add back the old set of buttons.
3760 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
3762 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
3763 Roll VERSION to 3.94 (not yet final though).
3765 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3767 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
3768 obstack_int_grow, obstack_int_grow_fast): Eliminate
3769 cast on left of assignment, which gives MIPS cc fits and is
3772 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
3773 F_ALIAS. Use printf, not fprintf, when not passing a file
3775 (compare_opcodes): Check that identical instructions have
3776 identical opcodes, complain otherwise.
3778 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
3779 was reported by Roland McGrath.
3780 (unimp): Only match if exactly zero instruction. (Roland)
3781 (branches and traps): Generate all variations of these
3782 instructions with macros, based on a single call that defines
3783 each condition name and its binary representation.
3784 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
3786 * valprint.c (val_print_fields): Take, and use, format parameter.
3787 This means that "p/x struct" again prints the elements in the
3788 desired format. Changed callers.
3790 * stack.c (frame_info): Use filtered output, and indicate wrap
3791 points. Remove kludgy formatting designed to avoid line wrap.
3793 * utils.c (wrap_here): If the line is already full (because
3794 we had printed a long indent or long wrapped string), do an
3795 immediate newline-and-indent.
3797 * m68k-pinsn.c (print_insn_arg): Bugfix from
3798 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
3799 instruction is incorrectly disassembled as bkpt #8.
3801 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
3802 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
3803 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
3804 and then will dump core (sometimes). I traced it back to an
3805 uninitialized symfile_name in psymtab_to_symtab.
3806 (const_vol_complaint): Add quotes to message.
3807 (define_symbol): Only believe line number if gcc_compiled.
3808 Avoid allocating symbol if we will not return it.
3810 Add target strata support so that newly established targets go
3811 into their right place in the target stack (e.g. a new exec file
3812 doesn't wipe out the ability to access the running process).
3814 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
3815 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
3816 and initialize it properly in all the targets.
3818 * target.h: Document strata. Change return type of push_target.
3820 * target.c (nomemory): new function for dummy memory access.
3821 (tcomplain): Rename complain, now also used in symfile.c.
3822 (push_target): Push targets within strata. New return value shows
3823 whether new target is on top of stack or not. Always keep dummy
3825 (target_files_info): Ignore dummy target.
3827 * core.c (core_open): Warn user, and skip accessing file, if the
3828 core target is not the topmost target in the stack.
3829 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
3832 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
3833 target_ops, it doesn't belong there since we have no regs there.
3834 Change name of target from machine => memory to clarify.
3836 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
3838 * Freeze version 3.93 for release.
3840 * Makefile.dist: Handle vx-share and nindy-share subdirs
3841 properly when building gdb.tar.Z.
3843 * symtab.c: lint; add no_symtab_msg to consolidate the messages
3844 printed in various places, so I could change just one copy.
3846 * dbxread.c, coffread.c: Change references to bfd->iostream
3847 to cast to FILE *, now that BFD avoids needing types defined
3848 in other header files.
3850 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3852 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
3853 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
3854 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
3855 (actually gcc -Wall).
3857 * dbxread.c: Remove first_global_sym, last_global_sym, since
3858 they are never referenced.
3860 * defs.h (baud_rate): Declare.
3861 main.c: Define it, and add the -b option to set it.
3863 * gdb-int.texinfo: Add text on how to define a new host or target
3864 architecture, prompted by Per Bothner's questions about MIPS
3867 * gdb.texinfo: Document "complaints". Change doc of -q since
3868 gdb no longer prints the copyright and blurb if you specify a file
3869 name to be debugged (just like Emacs). Add doc for Nindy-specific
3870 command line flags for specifying target serial port and such.
3871 Update copyright to 1991.
3873 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
3874 has taken over for us the job of ripping up executable files. The
3875 crud caused Per Bothner's port to not compile.
3877 * infrun.c (normal_stop): Avoid printing "Program exited
3878 normally" if we are in batch mode. This allows a GDB which
3879 executes a program on a target system, to behave like a Unix
3880 command (input from stdin, output to stdout, no extraneous
3883 * main.c (main): Allow additional machine-dependent command line
3884 options to be specified with the ADDITIONAL_OPTIONS,
3885 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
3886 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
3887 processing to occur just before the main loop with
3888 BEFORE_MAIN_LOOP_HOOK.
3889 (main): If a "core file" argument is specified, and it is not a
3890 core file, try it as a process ID to attach.
3891 (symbol_completion_function): Attempt to cope with
3892 "show screen-" TAB, not very successfully. This needs more work,
3894 (batch_file): New function, returns whether we are reading
3895 commands from an interactive tty on stdin, or from somewhere else.
3896 Called by normal_stop since it doesn't get from_tty passed down
3897 to it like many commands do.
3899 * remote-nindy.c: Handle command line options for nindy
3901 (nindy_before_main_loop): Prompt user for tty name if they
3902 don't specify it before getting to the interactive command loop.
3904 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
3905 and -r command line options. Also add hook before main loop
3906 to make it easy to specify a tty.
3908 * TODO: More things to do, one done.
3910 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
3912 * dbxread.c: Make complaint() calls pass pointer, not struct.
3913 Add complaints about badly formatted C++ type information
3914 (const/volatile indicator, and parse errors resulting in
3915 error_type). Fix C++ virtual member fn comment.
3916 (read_struct_type): Avoid bumping pointer if we got a parse
3917 error; this prevents our walking beyond the end of a string.
3918 Terminate loop on null char as well as semicolon.
3919 (process_one_symbol): Fix the LBRAC fix so that it uses the
3920 last previous SLINE, FUN, or SO record's PC address. C++ debug
3921 symbols did not have SLINE records in a useful order compared
3922 to the LBRAC records.
3923 (define_symbol): Handle "catch" records.
3925 * symtab.c (check_stub_type): Added new complain
3926 `stub_noname_complain' and added a consistency check to
3927 keep the debugger from crashing when finishing from an
3928 exception frame. A real fix will be needed later.
3930 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
3932 * infcmd.c (attach_command): Make global.
3934 * Makefile.dist (REMOTE_OBS): Make these compile by default,
3935 but make them easy to comment out. Perhaps later they should
3936 be enabled by what CPU you configure for? FIXME.
3937 (VERSION): Roll to 3.93.
3938 (pinsn.o): Remove rule for obsolete file.
3939 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
3941 Run down a problem that manifested by printing the wrong function
3942 name in stack traces of read_ofile_symtab. Turned out that the
3943 problem was the SunOS 4.1.1 (and previous) C compiler outputs
3944 the LBRAC symbol with an address in the *data* segment, which
3945 blew our binary search through the blocks.
3947 * dbxread.c: Use the complain() facility consistently to bitch
3948 about problems in the symbol file we are reading.
3949 (finish_block): Add code to check the nesting of the blocks;
3950 complain and Procrust them to fit if wrong.
3951 (make_blockvector): Check the order of the blocks, complain
3952 [but don't cope] if wrong.
3953 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
3954 symbols to be sure their PC value is greater than the last SLINE
3955 (line number) symbol we've seen, complaining and adopting the
3956 SLINE PC value if wrong.
3958 * symfile.h (struct complaint, complaint_root, complain,
3959 clear_complaints): Add.
3960 * symfile.c (complain, complaint_root, clear_complaints): Add
3961 facility to deal with non-fatal complaints and to regularize their
3963 (symbol_file_add): Clear complaint counters to allow new complaints.
3964 (initialize_symfile): Add 'set complaints' and 'show complaints'.
3966 * dbxread.c (dbx_symfile_read): Remember the address and size
3967 of the string table for the main symbol file, so we won't read it
3969 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
3970 to avoid reading the string table yet again. Lint.
3971 (throughout): Improve filtered output, including word wrap.
3972 (read_range_type): Improve Bothner's fix to handle other types too.
3974 * utils.c: Improve line wrap implementation. Handle unlimited
3975 width by making chars_per_line unsigned.
3976 (puts_filtered): New, easy, function.
3978 * defs.h (puts_filtered): add.
3980 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
3981 call the identical sort_symtab_syms() in symfile.c instead.
3983 * expread.y: Suggest the `file' command rather than `symbol-file'.
3985 * command.h (enum var_types): Add zinteger for seroable
3987 * command.c (do_setshow_command): Handle var_zinteger. Restructure
3988 nested if's into a switch.
3990 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
3991 we did not stop because of a breakpoint (it must have been for
3992 some other reason, like a "stepi"), so don't print anything.
3994 * symtab.c: Include <sys/types.h> all the time. Now that BFD
3995 doesn't include <sys/types.h>, old SunOS's require it for
3998 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
4000 A test port of gdb-3.92.6 to the Sony NEWS.
4003 Don't normally link in remote- or vx stuff.
4004 Some of it doesn't compile, and it wastes space for 99% of the users.
4005 Remove reference to no-longer-used HAVE_VPRINTF.
4006 Fixed BFD_DEP typo to BFD_DIR.
4008 Fix cast in arg to bfd_h_getlong.
4009 Make char *prefix be const.
4010 Fix how certain range types are mapped into builtin unsigned int types.
4012 Remove 2 #includes. They cause errors (on Sony, at least),
4013 and aren't needed (they wern't in earlier versions).
4015 print_address_symbolic should never demangle labels
4016 (since it prints *assembler-level* labels).
4018 [This was superseded by the change to printcmd below.]
4021 Add some "volatile" return types to avoid warnings.
4022 If MISSING_VPRINTF add vprintf function and not just macro
4023 (since vprintf is used in printcmd.c).
4025 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
4026 (The latter isn't grokked by some PCC-based compilers.)
4028 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
4030 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
4031 * nindy-share/coffstrip.c
4032 Added some forward declarations (otherwise, gcc complains
4033 about implicit extern redefined as static).
4035 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
4037 Changes inspired by Per Bothner:
4038 * printcmd.c (print_address_symbolic): Take additional parameter
4039 specifying whether to demangle.
4040 (print_address): Pass in asm_demangle to control demangling.
4041 (print_address_demangle): New fn, takes explicit arg to control
4043 * utils.c: Add new vars demangle and asm_demangle, and let them
4045 (fputs_demangled): If !demangle, just print the argument.
4046 (fprint_symbol): If !demangle, just print raw symbol.
4047 * valprint.c (val_print): Call print_address_demangle rather than
4048 print_address, to cause demangling to depend on the global
4049 rather than assembler-level demangling setting.
4050 * WHATS.NEW, gdb.texinfo: Document.
4052 * main.c (show_command): Show all settings if no arg.
4053 (initialize_main): Make "info set" the same as naked "show".
4054 * command.c (cmd_show_list): Handle prefix commands in the
4055 list, and print the name of the setting as well as its English
4056 description and value.
4058 Allow gdb functions to specify where a line should wrap if it
4059 exceeds the size of a terminal line. Use it to make the output
4061 * utils.c (set_screen_width_command): New fn, mallocs a buffer
4062 of the right size when screen width changes.
4063 (set_screensize_command, screensize_info): Remove #if 0'd fns.
4064 (wrap_here): New fn, indicates a point in the output where we
4065 should wrap the line rather than just letting it overflow at a
4067 (fputs_filtered): Implement wrapping.
4068 (n_spaces): New fn, returns a pointer to N spaces.
4069 (print_spaces_filtered): Use n_spaces.
4070 * defs.h (n_spaces): Declare.
4071 * stack.c (print_frame_info): Wrap with 4-space indent after
4072 fn name and before filename and line number.
4073 * printcmd.c (print_frame_args): Wrap with 4-space indent
4074 before each argument name is printed.
4075 * valprint.c (value_print): Wrap with no indentation before
4077 (val_print_fields): Wrap with indentation relative to nesting
4078 level before each field name.
4079 (val_print): Wrap with nesting indentation before array elements.
4080 * command.c (do_setshow_command): Avoid extra newlines,
4081 wrap with 4-space indent around values printed, end with period.
4082 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
4084 * breakpoint.c (breakpoint_1): Implement addressprint for
4085 "info breakpoints" display. Change file name and line number
4086 format to " at file:nnn" rather than " (file line nnn)".
4087 * gdb.texinfo: Document.
4090 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4092 Frozen for gdb-3.92.6 release.
4094 README, WHATS.NEW: Update for 3.92.6 release.
4096 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
4097 coffread.o from configs since it is now built by default.
4098 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
4099 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
4100 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
4101 from configs since it is now built by default.
4103 Makefile.dist: Update for release 3.92.6. Handle files that
4104 have been moved to ../include, ../getopt, or ../bfd. Add
4105 saber.suppress and tests directory. Add config.status to
4106 the release (it will say "none").
4108 coredep.c: Minor formatting fixes.
4110 These changes were made in early December but only checked in now:
4111 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
4112 nindy-share/nindy.c: lint
4113 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
4114 register values coming back from the target; we store values
4115 in target byte order everywhere.
4117 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
4119 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
4121 * valprint.c (cplus_val_print, val_print_fields): New functions,
4122 which print C++ objects. They conspire to avoid printing a
4123 virtual base class more than once, following all the twists and
4124 turns of C++ virtual base rules.
4125 (val_print): Call the above rather than do it by hand.
4127 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
4128 symbol file, not for added files like shared libs. This really
4129 needs to be generalized to a timestamp per file.
4131 * core.c (cleanup_core): Avoid coredump if no core file.
4133 * config.gdb: Accept -host or -target in place of +host or
4136 * coffread.c (find_linenos): Avoid desupported BFD interface
4137 to line numbers. We still read them manually rather than using
4138 BFD's "generic" features.
4140 * gdbrc.tex, threecol.tex: Add GDB reference card and its
4142 Makefile.dist: Add refcard to OTHERS list for creating tar files.
4144 * Makefile.dist: Eliminate use of $< in explicit targets.
4146 * readline/Makefile: Use $< rather than $*.c, which does not
4147 include the VPATH in GNU Make.
4149 * tconfig/i960-bout, tconfig/i960-coff: These are identical
4150 copies of tconfig/i960, added for global configuration
4151 compatability. All i960 versions can read both coff and b.out.
4153 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
4154 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
4157 * TODO: Think of more things to do.
4159 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
4161 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
4162 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
4163 64-bit float conversion.
4165 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
4166 equivalent to sun?os4 so global config works.
4168 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
4170 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
4172 * main.c: Only declare linesize once; declare pagesize not at
4173 all, since it is never used.
4174 (main): Clear newly allocated line before it is used.
4176 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
4178 Further stabilization for the Intel 960.
4180 * Makefile.dist: Parameterize the location of the "include"
4181 and "bfd" directories, as well as "getopt". Add symfile.c.
4182 Link in both dbxread and coffread. Fix up "make depend" to
4183 rewack the locations of include, bfd, and getopt in its output.
4185 * README: Document moving include files, improve some of
4188 * coffread.c: Move common code out to symfile.c. Change
4189 symbol_file_command style interface to use new *_symfile_init
4190 and *_symfile_read interface under BFD. Use BFD internal
4191 info to locate line table, symbols, etc.
4193 * core.c (core_fetch_registers): Rename to get_core_registers
4194 to avoid confusion with fetch_core_registers.
4195 (register_addr): Move to coredep.c, which is already machine
4196 dependent. This leaves core.c pretty clean of dependencies.
4198 * coredep.c (register_addr): Accept this routine from core.c.
4200 * dbxread.c: Move common code (with coffread.c, etc) into new
4201 symfile.c. Each psymtab now contains a pointer to the
4202 format-dependent function that knows how to read it in. Make
4204 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
4205 (process_one_symbol): Add code to complain about a "compiler bug
4206 we muzzle here", if we actually see it.
4208 * eval.c (evaluate_subexp): Insert missing "break" statements
4209 in code that determines whether a variable is an lvalue in
4210 memory, register, or whatever. I detected this via a compiler
4211 bug in which it *almost* mashed out the whole switch statement.
4213 * gdb-int.texinfo: Add minor sections on configuring gdb for
4214 release, and about the README file.
4216 * infcmd.c (registers_info): Fix formatting somewhat. Still
4217 not as pretty as before, but it handles byte swapping.
4219 * remote-nindy.c: If data cache routines are interrupted while
4220 waiting for the remote end, be sure that any uninitialized cache
4221 blocks are on the free list, not on the valid list!
4223 * symfile.h: Flesh out this header file with all the various
4224 routines and variables that have been merged in from dbxread.c
4225 coffread.c, and symtab.c to symfile.c.
4227 * symfile.c: New file, containing code common to dbxread.c,
4228 coffread.c, and some code from symtab.c. All generic code for
4229 reading symbol files should be in here now.
4230 (unrecord_misc_function): Remove unused function.
4232 * symtab.h: Remove file-reading things to symfile.h.
4234 * symtab.c: Remove file-reading things to symfile.c.
4236 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
4237 to decode i960 fault types.
4239 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
4240 target.c: Change type of the "resume" function from int to void,
4241 since its result was never used.
4243 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
4245 * main.c: Replace "stupid" with "caution"; you now "set caution
4248 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
4250 * infcmd.c (do_registers_info): Call val_print to deal with the
4251 byte order of the registers being printed. FIXME, this makes
4252 the formatting of the output uglier.
4254 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
4255 defined, call it for signals the debugger doesn't itself use.
4256 The i960 uses this for more detailed fault information.
4258 * remote.c (remote_open): If arg is null, print help rather than
4261 * sparc-xdep.c (register_valid): Avoid declaring size, since
4262 various modules will think of various sizes depending on the
4263 architecture of their tm-file. FIXME, we need protection against
4264 actually entering one of those modules, which would clobber
4265 storage if not for the target architecture compiled into gdb.
4267 * stack.c (up_command, down_command): Always print the frame
4269 (up_silently_command, down_silently_command): New commands
4272 * i960-pinsn.c (reg), i960-tdep.c: Lint.
4274 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
4275 more parameters than it used to.
4277 * findvar.c (registers): Increase slop to 256 bytes, which should
4278 protect us against even most RISC machines with large register
4280 (locate_var_value): Move declaration inside related ifdef.
4282 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
4283 throughout, to avoid throwing away buffered input from the board.
4284 (nindy_wait): Supply_register takes addr_of_value, not value.
4285 (i960_print_fault): Renamed from i80960_fault.
4286 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
4287 (nindy_store_registers): Avoid regs_changed stuff, just stuff
4289 (nindy_create_inferior): Don't bother to write PC_REGNUM since
4290 we can set the PC in the call to proceed(). Unpush nindy_ops
4291 before pushing it on top, to avoid message to user. Eliminate
4292 commentary from Unix machines that just misleads here.
4293 (reset_command): Fix error message to suggest target command.
4295 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
4297 Release 3.92.5 as frozen.
4299 Stabilize the merged release...with help from lint, Saber C,
4302 Everywhere: Add include files needed to declare return types
4303 of functions called.
4305 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
4307 * breakpoint.h: Add undeclared breakpoint functions, and some
4308 functions for display handling since I couldn't think of a better
4311 * breakpoint.c (insert_breakpoints): Make code for disabling
4312 shared library bkpts more likely to work. It's used when we
4313 rerun a program and stop before the shared library has been
4315 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
4316 cast from pointer, so it squeezes through catch_errors.
4317 (bpstat_stop_status): Fix logic broken some time ago. We now
4318 always create a bpstat if the stop address matches a breakpoint,
4319 even if we don't stop there -- just like the old code used to do
4320 before I got my fingers into it (sigh).
4321 (breakpoint_1): Print "ignore count" after "stop only if"
4322 condition, since that's how it actually works.
4323 (mention): Handle watchpoints as well as breakpoints.
4324 (watch_command): use set_raw_breakpoint and mention to do most
4325 of the work (and initialize all the fields!). Only pass one
4326 arg to parse_c_expression, since that's all it takes.
4328 * command.c (not_just_help_class_command): Rename arg to args
4329 since we ignore "unused argument" warnings on vars named "args".
4330 inflow.c (child_terminal_info): ditto.
4331 infptrace.c (kill_inferior): ditto
4332 main.c (catch_errors, version_info, quit_command, pwd_command,
4333 source_command, dump_me_command, editing_info,
4334 set_history_size_command, set_history, show_history,
4336 stack.c (locals_info): ditto
4337 target.c (target_files_info): ditto
4338 valprint.c (set_input_radix, set_output_radix): ditto
4340 * core.c: Remove old variables for handling core and exec file
4341 sections (data_start, data_end, stack_start, stack_end,
4342 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
4343 text_end, exec_data_start, exec_data_end, text_offset,
4344 exec_data_offset, data_offset, stack_offset). They're
4345 superseded the more general build_section_table and
4347 (get_exec_file): Mention the `file' command.
4348 (read_memory_check): Rename to memory_error, and only call it
4349 in the case of an actual error.
4350 (read_memory, write_memory): call memory_error.
4351 (core_fetch_registers): Register section name is ".reg".
4353 coredep.c: Remove a bunch of crud now that all this file does
4354 is pull the registers out of a core file.
4355 (fetch_core_registers): Rewrite to actually work, I hope.
4357 dbxread.c: Use a.out.gnu.h, not system a.out, now.
4358 Replace index() with strchr(). Remove all the pre-BFD macro
4359 definitions for accessing the symbol file.
4360 (struct dbx_symfile_info): Encapsulate the information that
4361 dbx_symfile_init needs to pass to dbx_symfile_read in this
4364 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
4365 dbx_symfile_discard): Rearrange symbol file reading to divide
4366 the format-specific part from the format-independent part,
4367 leaving the format-independent part such as file name expansion
4368 and opening in symtab.c. This replaces
4369 partial_symbol_file_open and partial_symbol_file_read.
4370 Symbol_file_read, add_file, add_file_target_command,
4371 add_file_addr_command move to symtab.c. Pass an explicit
4372 "mainline" flag for when reading the main symbol table, rather
4373 than relying on the offset address to be zero or nonzero.
4375 (dbx_symfile_read): Don't allow void *'s to be printed as
4377 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
4378 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
4379 macro" debug version really work.
4380 (read_dbx_symtab): Remove unref'd parameter inclink.
4381 Avoid swapping N_SLINE symbols, for speed.
4382 Merge N_TEXT!N_EXT case with the other external symbol
4383 definitions' case. Add comments.
4384 (start_psymtab): Allocate the symfile name in the psymtab on
4385 the psymbol_obstack, rather than using the caller's storage.
4386 (end_psymtab): Only allocate a dependencies list if there are
4388 (psymtab_to_symtab_2): Use BFD when reopening file to read
4389 its symbols for real.
4390 (read_struct_type): Add FIXME comments where it needs work
4392 (read_huge_number): Add FIXME about overflows.
4393 (read_range_type): Add FIXME about comparing a long to 1<<32.
4395 * coffread.c: Minor changes to move things closer to the new
4396 regime with symtab.c and dbxread.c Major work is still needed
4399 * exec.c (exec_file_command): Remove old variables (see core.c
4401 (xfer_memory): If memory transfer is right at the end of a
4402 section, don't lose.
4404 * findvar.c (get_saved_register): If value is in a real
4405 register, LVAL is lval_register, not lval_memory.
4407 frame.h: Declare print_sel_frame and record_selected_frame.
4409 gdb-int.texinfo: New file, for GDB internals documentation.
4410 Very simple, unformatted doc of cleanups is there for now.
4412 gdbcore.h: Remove obsolete variables that described a.out
4413 section addresses and offsets. (See core.c above.)
4414 Declare fetch_core_registers and registers_fetched.
4416 getopt.c: Declare char *alloca(); even on SPARC.
4418 infcmd.c (run_command): Call target_kill rather than
4420 (step_command, next_command, stepi_command, nexti_command):
4421 Declare from_tty parameter even though we don't use it.
4422 (run_stack_dummy): argument BUFFER is a char array, not
4423 a pointer to REGISTER_TYPE.
4424 (finish_command): using_struct_return needed a value *,
4425 not a struct symbol *.
4427 * infptrace.c (child_xfer_memory): To avoid dependency on
4428 where sections are in memory, try PT_WRITE_D and if that fails,
4429 try PT_WRITE_I. Most Unixes don't care which you use.
4431 * infrun.c (step_resume_break_shadow): Change to array to
4432 match other breakpoint shadow storage.
4433 (clear_proceed_status): Pass address of bpstat to
4434 bpstat_clear, not the bpstat itself.
4435 (child_create_inferior): FIXME comment about if the child
4437 (start_inferior): Remove old function.
4438 (child_open): Use target_kill rather than kill_inferior.
4439 (wait_for_inferior): Ditto.
4440 (insert_step_breakpoint, remote_step_breakpoint): Use
4441 new step_resume_break_shadow.
4443 * inftarg.c (child_wait): If all child processes die,
4444 pretend that the one being waited for exited with signal 42.
4446 * main.c (command_line_input): When scanning for comments,
4447 don't coredump on unclosed quotes.
4448 (quit_command): Use target_kill rther than kill_inferior.
4449 (_initialize_main): Rename class_user from "user" to
4452 * printcmd.c (print_command_1): Initialize "fmt" if no format
4453 is specified by the user.
4454 (print_frame_args): Only add to args_printed if we are
4455 actually fetching args from the stack (avoiding undefined
4457 (_initialize_printcmd): Remove bogus \{ from string.
4459 * remote-eb.c (eb_open): Avoid coredump on no argument.
4461 * remote-nindy.c: Bring out of Intel environment into new
4462 target environment. Remove all conditional compilation on
4463 I80960. Massive hacking throughout.
4464 (nindy_xfer_inferior_memory): New routine stolen from
4466 (nindy_create_inferior): New routine pieced together, probably
4467 not quite working yet.
4468 (nindy_ops): New target_ops struct for nindy.
4470 * remote-vx.c: Use write_memory rather than target_write_memory
4471 to get error checking.
4472 (vx_add_file_command, vx_open): Use symbol_file_add rather than
4474 (vx_create_inferior): Use target_terminal_ours...
4476 * signame.c (_initialize_signame): Always initialize, since
4477 we need the table for things other than psignal.
4479 * solib.c (solib_add): Use symbol_file_add, not add_file.
4480 (solib_address): Return boolean result rather than struct
4481 pointer which nobody else knows the type of.
4483 * sparc-tdep.c, valops.c: Use write_memory rather than
4484 target_write_memory, to get error checking.
4486 * stack.c (locals_info, catch_info, args_info,
4487 get_selected_block, frame_command, up_command): Use
4488 target_has_stack, rather than have_inferior_p or
4491 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
4493 * symfile.h: New file, defining the interface between the
4494 generic and object-file-specific symbol reading code.
4496 * symtab.c: Move generic symbol-reading interface to symtab.c,
4497 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
4498 table to map BFD targets to symbol-reading modules in GDB.
4499 Change index to strchr.
4500 (lookup_struct_elt_type): Use error() rather than hand-made
4501 simulations thereof.
4502 (lookup_partial_symbol): Speedup slightly when length == 0.
4503 (symbol_file_add): New function.
4504 (symbol_file_command): Call it.
4505 (symfile_open, symfile_init): New function.
4506 (add_file_target_command, add_file_addr_command): moved from
4509 * target.c (target_command): use target_kill.
4511 * target.h (target_files_info): Don't declare, never called
4514 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
4515 files to determine stack end address.
4517 * valarith.c (value_x_binop, value_x_unop): Change error message
4518 to be more useful. Pass proper argument to value_struct_elt.
4520 * valops.c (value_assign): FIXME comment that long long
4521 bitfields will break here.
4523 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
4524 Update `make saber_gdb' to work better.
4526 * TODO: A woman's work is never done.
4528 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
4529 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
4530 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
4531 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
4532 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
4533 valops.c, valprint.c, exec.c: Lint.
4536 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
4538 Continuing Intel 960 port merge of GDB.
4540 * Makefile.dist: Merge i960 "nindy-share" files. Rename
4541 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
4542 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
4543 Wack over "make depend" so it handles files in subdirectories
4544 vx-share, nindy-share, bfd, and in the current directory.
4546 * blockframe.c (get_prev_frame_info): Remove fatal error
4547 if stack not defined.
4549 * core.c (core_open, core_detach): New functions that handle
4550 the old "core-file" command as "target core" and "detach" instead.
4551 (core_file_command): Call them.
4552 (core_xfer_memory): Use common routine xfer_memory.
4554 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
4555 dbxread now uses bfd for everything but symbol reading itself.
4556 BFD internals are used to drag out the relevant file offsets.
4557 (partial_symbol_file_open): Change args all around for BFD.
4559 * symtab.c: Rename "value" to "val" everywhere, so we can
4561 (symbol_file_command): New command, moved from dbxread.c
4562 and coffread.c. It uses BFD to read the file, then vectors
4563 based on its type, to dbx or coff symbol readers.
4564 * symtab.h: Extern a few vars for symbol_file_command.
4566 * target.h: Breakpoint takes a char * save area, not a char **.
4568 * valprint.c (val_print): When unpacking bitfields, offset
4569 the address in gdb of the value, if it is declared with a shorter
4570 type. Remove the last "runtime kludge test" of host byte order.
4572 * utils.c: Remove old my_bfd_read routine.
4574 * stack.c (frame_info): Use target_has_stack. Print program counter
4575 register's actual name rather than "pc", since it's called the
4576 "ip" (instruction pointer) on the i960 (sigh).
4578 * target.c (target_command): Add command for selecting a target
4579 type and calling its open routine. This is used for initiating
4580 communication with a particular target, in a generic way.
4582 * tm-i960.h: Update for modern gdb. Remove semicolons from
4583 various macros. Handle reading struct return convention, and
4584 error-out attempts to return structs with the "return" command.
4585 Be sure gdb doesn't think we know how to call functions in the
4588 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
4589 to i960_xxx in lower case.
4590 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
4591 not being defined yet.
4593 * remote.c (remote_open): Call start_remote to initialize
4594 wait_for_inferior during open.
4595 (remote_xfer_inferior_memory): Return length written rather
4598 * remote-vx.c (target_command -> vx_open): Use new generic
4600 * remote-eb.c, inftarg.c, exec.c: ditto.
4602 * infrun.c: Fix comments.
4603 (attach_program -> child_open): Use new generic target command.
4604 (wait_for_inferior): Clear saved register values before target_wait,
4605 so target_wait can set some of them if convenient.
4607 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
4608 Return success indicator, not void.
4609 (child_xfer_memory): Avoid fetching initial word if we'll
4610 overwrite it anyway.
4612 * infcmd.c (attach_command): Use new generic target open routine.
4613 (_initialize_infcmd): Update doc on attach and detach commands.
4614 (do_registers_info): Merge in a byte-order problem as a FIXME
4617 * findvar.c (find_saved_register): Avoid problem in current frame.
4618 (read_relative_register): Ditto.
4619 (write_register): Convert byte order on the way out.
4621 * exec.c (file_command): Add.
4622 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
4623 (xfer_memory): Common function between core_xfer_memory and
4625 (exec_xfer_memory): Use it.
4627 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
4629 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
4630 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
4631 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
4633 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
4635 Merge Intel 960 port of gdb, continuing...
4637 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
4638 symbol_file_command): Pass from_tty arg to hush 'em up.
4640 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
4641 Add magic numbers for 960 COFF format.
4643 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
4645 Merge Intel 960 port of gdb, from Intel "1.2" release.
4647 CHANGE_LOG entries from their port, which was based on
4650 Thu Sep 6 11:02:22 PDT 1990
4651 Remove temp file if download is interrupted.
4653 Wed Aug 1 09:08:33 PDT 1990
4654 Now uses binary protocol to talk to NINDY.
4655 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
4656 Times out after 5 seconds when trying to talk to NINDY.
4658 Tue May 29 12:54:49 PDT 1990
4659 Added variable baud rate (-b switch).
4660 Source code reorganization.
4662 Thu Apr 26 11:09:55 PDT 1990
4663 More cleanup of batch mode; specifically, execute "-s", "-e", and
4664 "-se" switches as soon as they are encountered on the invocation line.
4666 Fri Apr 20 13:47:15 PDT 1990
4669 Thu Apr 19 09:54:28 PDT 1990
4670 Add 'reset' command.
4672 Wed Apr 18 09:48:07 PDT 1990
4673 After opening remote tty, wait for 1 second to go by without input
4674 from it before trying to talk to NINDY (fixes problems with the
4675 Heurikon HK80/V960E).
4677 Mon Apr 4 16:33:05 PDT 1990
4678 Some output was not being suppressed in 'batch' mode.
4680 Thu Mar 22 15:31:11 PST 1990
4681 Ask user if old symbol table should be deleted when new file is
4684 Allow user to run a program downloaded before gdb960 was brought up.
4686 Correct "exec-file" help message for i80960 context.
4688 Correct bug in calculating user space address: could occasionally
4689 corrupt user program.
4691 Make sure to zero low-order bits in rip's because of bug in 960CA
4692 A-step part: could cause operation faults when "next"ing across
4695 Correct bug that made it impossible to get source line numbers for
4696 code loaded at addresses higher than 0x7fffffff.
4698 Wed Jan 10 12:43:22 PST 1990
4699 Open remote tty for exclusive use.
4701 Fri Jan 5 12:14:42 PST 1990
4702 Correct disassembly (CA manual was right after all):
4703 opcode for sysctl is 0x659
4705 Mon Oct 23 12:03:04 PDT 1989
4706 Use G960BASE and G960BIN environment variables to find 'sx' utility.
4708 Mon Oct 16 14:15:09 PDT 1989
4709 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
4711 Mon Oct 2 15:56:31 PDT 1989
4713 Added 960CA disassembly support.
4715 To simplify maintenance:
4716 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
4718 - eliminated opcode.h: incorporates tables into i960-pinsn.c
4719 - moved 960-specific routines from i960-pinsn.c to i960-md.c
4720 - made disassembly interface identical to that in gdmp960.
4724 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
4726 * target.h: Allow targets to stack. Add target_has_memory,
4727 _registers, etc. Restructure memory access and "info files"
4728 to walk the target stack.
4729 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
4730 target.c: Change tables to match target.h.
4731 * inflow.c (child_mourn_inferior): pop child_ops.
4732 (generic_mourn_inferior): Use new has_stack flag.

4735 * remote-eb.c: New memory regime, new info files.
4736 * remote-vx.c: New memory regime, new info files. Now use
4737 separate targets for VxWorks attachment to machine, and
4738 actually running a process under VxWorks, since one has
4739 stack & execution & regs and the other doesn't.
4740 * remote.c: New memory regime, new info files.
4741 * sparc-xdep.c (fetch_core-registers): New memory regime.
4742 * target.c: New routines and support for stacked targets,
4743 new memory regime, new info files regime.
4746 Generalize section handling for an arbitrary number of sections,
4747 including use of the new BFD (binary file) library.
4748 * gdbcore.h: Add struct section_table.
4749 * exec.c (build_section_table): Iterate all sections and
4750 record what gdb needs to know about them.
4751 (exec_command): Use it.

4757 * dbxread.c: Quick changes to make it compile with new BFD.
4758 * utils.c (error): Avoid using bfd_error in generic routines.
4760 * core.c (core_fetch_registers): Get from the ".regs" section of
4762 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
4764 * inferior.h (attach_flag): Export.
4765 * infcmd.c (run_command): use new target_create_inferior.
4766 * infrun.c (child_create_inferior): Don't return result.
4767 * Makefile.dist (VERSION): 3.91.4.
4769 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
4771 * breakpoint.c (bpstat_num): Handle breakpoints which have
4772 since been deleted, such as temporary breakpoints.
4773 infcmd.c (program_info): ditto.
4775 * core.c (core_file_command): Display the frame where the core
4780 * remote-vx.c (target_command): Merge in target command from
4781 targ-vx.c. A few other cleanups.
4783 * TODO, Projects: Lots more stuff to do...
4785 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
4787 Massive changes to wall off the remote-debugging interface
4788 behind a function vector. The port to handle VxWorks targets
4789 is also part of this.
4791 All files: Replace references to renamed functions,
4792 remove references to remote_debugging, remove references to
4793 have_include_file, have_core_file in favor of target_has_stack,
4794 target_has_memory, etc.
4796 * Modularize the breakpoint interface.
4797 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
4798 a breakpoint instruction.
4799 breakpoint.c: struct breakpoint's shadow_contents now sized as
4801 (insert_breakpoints): Vector to target to install breakpoints.
4802 (remove_breakpoints): Vector to target here too.
4803 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
4804 sparc-tdep.c (single_step): Use new breakpoint interface for
4805 the single-step breakpoints.
4806 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
4807 New file, contains routines to insert and remove breakpoints by
4808 reading out the old contents and later replacing them. This is
4809 how ptrace breakpoints work, and many remote systems as well.
4811 * tm-vxworks68.h: New config file, overrides a few things for
4812 Wind River's preferences.
4814 * target.h: New file, for transfer vector used to talk to the
4815 inferior (child, attached, core, exec, remote, etc). All accesses
4816 to the thing being debugged should come through these vectors.
4817 target.c: New file, routines to handle transfer vector.
4818 (various files): Add transfer vectors XXX_ops for the various
4819 targets and pseudo-targets (core files, etc) we support.
4821 * breakpoint.c (bpstat_stop_status): Further explorations of
4822 watchpoints and why things don't work all the time.
4823 (bpstat_alloc): New fn to allocate a bpstat and chain it.
4825 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
4826 the local gdbinit if it doesn't already have it.
4828 * core.c (core_ops): add and install.
4829 Allow core debugging without exec file.
4831 * dbxread.c (free_and_init_header_files): Merge two fns.
4832 (end_symtab): Free named symbol table when a new version comes in.
4833 (read_dbx_symtab): Relocate all kinds of symbols with base
4834 address. First step toward handling different text, data, bss
4836 (add_file_addr_command): Renamed add_file_command.
4837 (add_file_command): Vector to remote handler.
4838 Add "load" as an alias for "add-file" command.
4840 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
4841 non-returning functions.
4843 * exec.c: Add exec_ops, and push it as a target when an exec
4846 * infcmd.c (run_command): Pass executable file name and arg list
4847 separately when starting an inferior. Permit "run" when no exec
4848 file is specified, for VxWorks.
4849 (detach_command): Move to child_detach in inftarg.c.
4851 * inftarg.c: New file. Unix-child-specific routines, and the
4852 child_ops structure.
4854 * inferior.h (registers): Export "registers" as the way for
4855 target dependent register handlers to find gdb's local copy of
4856 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
4857 since it is now used by places that want wait_for_inferior to
4858 handle the grunge but want to see every trap from the inferior.
4860 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
4861 Eliminate remote_debugging hooks in terminal handling.
4863 * infrun.c: Replace start_inferior with child_create_inferior.
4864 Move all the hair of Unix shells and ptrace idiosyncracies into
4865 child_create_inferior, so remote handlers don't have to deal.
4866 Remove running_in_shell. Rename stop_after_attach to
4867 stop_soon_quietly, and use it in a few other places where we want
4868 to just call wait_for_inferior and get control back on the first
4869 trap. trap_expected now never takes a value > 1.
4870 (init_wait_for_inferior): Initialize static vars when a new
4873 main.c (gdbinit): Add new hook for .gdbinit file name, let
4874 it be overridden by config files as GDBINIT_FILENAME.
4875 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
4876 Both of these are used for VxWorks gdb.
4878 mcheck.c: rename include file "gmalloc.c" to avoid problems
4879 with system include file "malloc.c".
4881 param-no-tm.h: New include file, same as param.h but does not
4882 include the default "tm.h" file. This is used in files where
4883 the target is known, e.g. remote-eb.c or sparc-xdep.c.
4885 param.h: Now just a shell that includes tm.h and param-no-tm.h.
4887 remote-vx.c: New file, VxWorks remote debugging support. Uses
4888 RPC routines that are shared with the target system, in directory
4891 remote.c: Vectorize remote interface.
4893 source.c: Globalize source_path, and make an alias "l" for "list"
4894 since we now have the "load" command.
4896 sparc-xdep.c: Use new param-no-tm.h.
4898 symmisc.c (free_named_symtab): Add new function from Wind River.
4899 However, ifdef it out for now while we think about what it should
4902 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
4904 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
4905 non-Unix-children handle this with their own code in the target
4908 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
4909 source and target lists. Add vx-share to default list of include
4910 directories. Add new files to src and target lists: mem-break,
4911 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
4912 ${srcdir} versions of munch and createtags are used.
4914 * valops.c (find_function_addr): Split out of call_function.
4915 (call_function_by_hand): Rename call_function; this function
4916 calls functions in the target by laboriously patching the target
4917 word-by-word with the right stack, args, regs, etc.
4920 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
4922 Handle AMD 29000 a bit better.
4924 * remote-eb.c (readchar): Mask received char log to make it readable.
4925 (remote_start): Pass arguments down to executing program.
4926 Make startaddr unsigned.
4927 infrun.c (start_inferior): Accept args, pass them to
4929 infcmd.c (run_command): Pass args down to start_inferior.
4931 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
4932 the target object file format.
4933 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
4935 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
4936 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
4938 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
4940 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.

4946 * Debug problems with dummy frames and calls to the inferior.
4947 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
4948 * sparc-tdep.c (do_restore_insn): Simplify.
4949 (sparc_frame_find_saved_regs): Simplify and fix what we find.
4950 (sparc_push_dummy_frame): Simplify and fix what we push.
4951 (sparc_pop_frame): Slightly more hair here, deciding whether
4952 we are restoring a saved PC or returning to a return address in %i7.
4953 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
4955 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.

4957 * obstack.h (chunkfun): ditto.
4958 * defs.h (xmalloc, xrealloc): ditto
4960 * utils.c (quit): Grab the terminal from the child if necessary.
4962 * inflow.c (term_status_command): Rename to term_info, change
4965 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
4966 (is_delayed_branch): Speed up.
4967 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
4968 Still missing some float ops, and needs testing.
4970 * Support for input and output radixes other than base 10
4971 * defs.h (input_radix, output_radix): Declare.
4972 * expread.y (yyparse, parse_number): Handle changes of input
4973 radix, and ambiguous names-or-numbers in radixes >10.
4974 * printcmd.c (print_scalar_formatted): Print formatted hex
4975 numbers in varying column widths.
4976 * valprint.c (val_print): Use output_format to print scalar ints.
4977 (set_input_radix, set_output_radix, set_radix): Create.
4978 (set_output_radix): Set output_format from output_radix.
4979 (_initialize_valprint): add `set radix' but leave the others off.
4981 * main.c (execute_command): Let stupid questions be turned off.
4982 (_initialize_main): Handle "set stupidity", etc.
4984 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
4985 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
4987 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
4989 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
4990 bfd stuff is still screwed up, but with some manual work, it
4993 * breakpoint.c (bpstat_do_actions): Start over if a command
4994 proceeds the inferior, since the inferior will have stopped and
4995 will need to have its new stop-actions taken care of.
4997 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
4998 compiler fits, simplify it.
5000 * gdb.texinfo (directory command): Doc new dir command.
5001 source.c (directory_command): "dir" now puts things on the front
5002 of the path, moves dups up front, and handles multiple names
5003 on the command line, inserting each one in order. It also
5004 blows away cached line and full_filename info.
5006 * stack.c (backtrace_command): Skip "more stack frames follow"
5009 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
5010 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
5011 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
5012 The only odd one was Gould NP1, which had defined vprintf to
5015 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
5016 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
5017 variable, inspect_it.
5018 valprint.c (print_string, val_print): Use the global inspect_it
5019 to indicate whether to print in Epoch style or normal style.
5021 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
5023 * printcmd.c (call_command): add an alias for the "print" command
5024 which runs expressions and doesn't print the result if void.
5025 (print_command_1): implement it.
5027 * command.c: Remove #if 0'd code. Initialize all the fields
5028 in add_cmd (). Rename do_nothing_command to
5029 not_just_help_class_command, and make it externally visible.
5030 command.h: add user_commands to struct.
5031 * main.c (define_command): Don't overload c->function with a char
5032 string as well as a function pointer.
5034 * eval.c (evaluate_subexp): Reinstall tiemann changes to
5035 calling convention of value_struct_elt () that got dropped in
5038 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
5039 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
5041 * tm-sparc.h (POP_FRAME): replace some constants with defines.
5043 * sparc-xdep.c (store_inferior_registers): defer stores to regs
5044 until a good time (e.g. when we are about to run the child),
5045 saving ptrace calls.
5046 * infrun.c (proceed): handle DO_DEFERRED_STORES.
5047 * tm-sparc.h: define DO_DEFERRED_STORES.
5049 * sparc-xdep.c (store_inferior_registers): when storing float
5050 registers, don't store stack regs too. When storing the SP,
5051 however, DO store the stack regs too. This fixes a bug in which
5052 the dummy frame is not recognized when a call_function finishes,
5053 because its frame pointer (in the stack regs) was never
5055 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
5056 even though we don't know how to read them from an inferior.
5057 valops.c (call_function): Comment about storing SP.
5059 * infrun.c (save_inferior_status): Save away the original bpstat
5060 chain so it can be restored later. Install the copied version for
5061 use by whoever saved the status. It will be blow away by
5062 restore_inferior_status, and the original chain restored. This is
5063 important for people who have pointers into the original.
5065 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
5066 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
5067 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
5070 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
5072 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
5073 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
5074 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
5076 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
5078 * Merge Mike Tiemann's multiple inheritance changes from Sun.
5079 Store the baseclasses in a type struct starting from array element
5080 0 rather than from the unusual array element 1.
5082 dbxread.c: the above.
5083 (virtual_context): Add
5084 Read new debug information about which virtual function table
5085 a virtual function is from, and store it in fn_field.fcontext.
5087 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
5088 TYPE_FN_FIELD_STATIC_P.
5090 symtab.c: the above.
5091 valops.c: the above. Handle pointer casts of object *'s.
5092 (search_struct_method): Add.
5093 (value_struct_elt): First arg is now a pointer to a value, and is
5096 valprint.c: the above.
5097 values.c (value_virtual_fn_field): Add type arg. Handle
5098 offsetting to the proper object when calling virtual fns.
5100 (baseclass_addr): Add valuep arg.
5102 * README: Document the current state of BFD config (missing).
5103 * TODO, ChangeLog, Makefile.dist: Roll version.
5104 * WHATS.NEW: Add summary of changes since 3.5.
5106 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
5108 * dbxread.c (read_struct_type): Clear bit vectors whenever
5110 symtab.c (B_CLRALL): define.
5112 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
5113 using == rather than =. Huh... This fixes the dreaded problem
5114 wherein builtin_type_int becomes TYPE_CODE_FLT.
5116 * core.c (info_files): Show the inferior pid.
5118 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
5119 already knows how to look in the source directory.
5121 * Remove psymtab hair from many places. Remove duplicated code
5122 for searching symbol tables. Hide psymtabs from most places.
5123 Make it fast to get from a psymtab to its symtab.
5125 blockframe.c (blockvector_for_pc): Remove psymtab hair.
5126 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5127 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5128 dbxread.c: export psymtab_to_symtab, make it work if called N times.
5129 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
5130 new symtab completely. New psymtabs get symtab pointer
5131 initialized to zero. Remove MI warning printf.
5132 symtab.h: Comments. Add psymtab to symtab pointer.
5133 (PSYMTAB_TO_SYMTAB): New macro.
5134 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
5135 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
5137 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
5139 (print_frame_info): Avoid special-casing symbols that have not yet
5142 * source.c (open_source_file): Quick path if we have already
5143 located the source file by its full name.
5145 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
5146 find_pc_psymtab. When a name is found in the misc function
5147 vector, search the symbol table for its mangled name, not the
5148 name that the user typed.
5150 * bfd.h: Fix missing comment terminators, make #endifs match.
5152 * valarith.c (value_less): Handle unsigned int comparisons.
5153 Add FIXME about pointer compares, which assume host and target
5154 pointers are the same.
5156 * command.c (do_nothing_command): lint
5157 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
5158 fix comments on debug symbol format for visibility. Actually set
5159 visibility of symbols.
5160 main.c (echo_command): lint; use <readline/history.h>.
5161 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
5162 obstack.h (_obstack_blank): Rearrange pointer math to avoid
5163 pointing past end of allocated memory; saber complains.
5164 obstack.h: Declare the external functions that we use.
5165 valarith.h: use <string.h>
5166 solib.c (solib_add): lint.
5168 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
5170 * main.c (initialize_main): Default info_verbose to off, now that
5171 symbol reading is fast.
5172 (quit_command): Avoid clobbering exec_bfd while quitting.
5174 * Initial BFD (binary file diddling library) merger:
5175 coffread.c: Change AOUTHDR to struct exe_hdr.
5177 core.c: initialize initialized data at compile time.
5178 (core_file_command): Move from coredep.c, convert to bfd.
5179 (xfer_core_file): Convert to bfd.
5180 exec.c (exec_file_command): use bfd routines.
5182 mips-tdep.c: Remove exec_file_command and friends.
5185 * coredep.c: (fetch_core_registers) Convert core_file_command to
5186 fetch_core_registers.
5187 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
5189 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
5190 (my_bfd_read): More bogosity, which I don't think we call.
5191 (program_name): Remove this atrocity asap!
5193 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
5196 values.c: allocate_repeat_value was not clearing the
5197 optimized_out field.
5198 (value_static_field): minor stylistic fix (wrong macro was used).
5199 valops.c (value_struct_elt_for_address): didn't work for C++
5202 * signame.c (_initialize_signame): Initialize signal names once.
5204 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
5205 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
5206 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
5208 * remote-eb.c: Support user-settable baud rates on the serial port.
5210 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
5212 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
5214 * tconfig/sun3os4: Remove warning about native assembler,
5215 since it also occurs in the xconfig file.
5217 * findvar.c (registers): Allocate some slop after `registers'
5218 to prevent stray accesses from trashing the next variable.
5220 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
5221 on the sun-3, by changing the #ifdef from `sun3' (which is not
5222 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
5223 vars, which happened to follow `registers' in the executable.
5225 * readline/history.c (history_search): Heed gcc-2's advice
5226 and parenthesize && inside ||).
5228 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
5229 tm-29k.c: Insert FSF copyright headers.
5231 * remote-eb.c: Better comments.
5233 * Makefile.dist: Update to 3.91.6.
5234 * TODO: note PREPARE_TO_STORE problem.
5236 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
5238 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
5240 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
5242 * infrun.c (wait_for_inferior, at end): Don't set up
5243 prev_* if the inferior no longer exists.
5245 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
5246 CANNOT_EXECUTE_STACK.
5247 valops.c (call_function): Use it.
5249 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
5251 * inferior.h (PC_IN_CALL_DUMMY): New macro.
5252 infrun.c (wait_for_inferior, 2 places): Use it.
5254 * values.c (value_being_returned): Only use
5255 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
5257 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
5258 right thing for remote-eb.c.
5260 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
5261 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
5263 * blockframe.c: Put get_frame_saved_regs inside #if !defined
5264 (FRAME_FIND_SAVED_REGS).
5266 * findvar.c ({fetch,store}_registers): Check for
5267 REMOTE_{FETCH_STORE}_REGISTER macro.
5269 * findvar.c (get_saved_register): Add argument lval and
5270 change meaning of argument addr.
5271 findvar.c: Change calls to get_saved_register to reflect
5272 new calling convention.
5273 valops.c (value_assign): Use get_saved_register instead of
5274 find_saved_register.
5276 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5278 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
5279 an (uninitialized) pointer to one. Use "&" when passing it
5282 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5284 * coffread.c (getfilename): Use DGUX x_offset and x_name if
5287 * coffread.c (symbol_file_command): Put semicolon after
5289 Put safe_to_init_tdesc_context in #if defined (TDESC).
5290 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
5291 coffread.c: #include <sys/stat.h>.
5292 (read_coff_symtab): Typo: in_source_files -> in_source_file.
5293 Add missing ')' in check for "lc%" and friends. Remove
5295 Declare read_one_sym() at top of file.
5296 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
5297 MC68WRMAGIC can have the same value without causing a duplicate
5300 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
5302 * Allow a Makefile to be built without building the
5303 tm and xm file links that screw up builds in subdirectories.
5304 This is done with `config.gdb none', then you can do things
5305 like `make gdb.tar.Z'.
5306 * tconfig/none: Config file for no target system
5307 * xconfig/none: Config file for no host system
5308 * config.gdb: If no TM or XM files are called out by the
5309 host or target file, don't make links for them.
5311 * cplus-dem.c: Add documentation.
5313 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
5314 simple error, so the user's gdb doesn't crash due to some object
5315 file problem (e.g. somebody is rebuilding the file out from under
5318 * printcmd.c (print_address_symbolic): demangle the symbol.
5320 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
5321 Motorola copyrights in it. Make "make gdb.tar.Z" work.
5322 (alldeps.mak): sort and uniq all results from this; duplicates
5323 hose gdb.tar.Z link building. Remove RCS files from
5324 tconfig and xconfig. Add config files for sun386. Add
5325 a few odd files to OTHERS and HFILES.
5327 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
5329 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
5330 Roll version number to 3.91.5. Make lint work in bindir.
5332 * README: Document cross-debugging and new file structure.
5334 * blockframe.c: Lint. Include "value.h" to declare read_register.
5335 (find_pc_partial_function): remove duplicate line.
5337 * command.h: Lint. Declare error_no_arg and dont_repeat.
5339 * tm-news.h: Remove inadvertently duplicated stuff.
5341 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
5342 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
5344 * config.gdb: Allow `config.gdb host target' form. Clean
5345 up previous change that printed bogus messages when you just said
5348 * core.c: #include "command.h" for lint.
5351 * main.c: Remove some casts of enums. Lint.
5358 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
5360 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
5361 read it from memory. This will allow us to save ptrace calls
5362 eventually. Changed caller single_step too.
5364 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
5365 that we aren't going to use, saving many ptrace calls, especially
5366 when watchpointing or single stepping. Use some #define's for
5368 (store_inferior_registers): Ditto.
5369 (core_file_command): Use some #define's for constants.
5371 * tm-sparc.h: Add #define's for some register numbers, so we
5372 can eliminate the use of random constants in sparc-xdep.c.
5374 * stack.c (frame_command, print_frame_info, up_command,
5375 down_command) Remove frame_changed, since it
5376 causes a bug and doesn't seem to do anything useful. In some
5377 places it was used as a flag, in others as a stack level (?).
5379 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
5380 default is to use the portable (vprintf) version rather than the
5382 * xm-news.h (MISSING_VPRINTF): Add.
5384 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
5386 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
5388 * Remove stuff that forces -Bstatic linking of gdb, and warnings
5389 about linking debugged programs -Bstatic in the sun?os4 config
5390 files in tconfig and xconfig subdirectories.
5392 * main.c (main): Remove unreached exit(0) now that we exit
5395 * Create TODO file for online bug list. There are too many
5396 "little" bugs to keep track of on paper.
5398 * Change Projects file to refer to bug-gdb@cygnus.com
5399 rather than kingdon@ai.
5401 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
5403 * Makefile.dist (VERSION): 3.91.4 now.
5405 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
5406 (condense_misc_bunches): Add sanity check that misc_count is
5407 the same as the number of symbols in the bunch.
5409 * coffread.c: rename init_misc_bunches. Pass an argument
5410 to condense_misc_bunches (a zero).
5412 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
5413 every time we are called; don't rely on our caller to do it.
5414 (add_file): Remove call to init_misc_bunches.
5416 * mipsread.c: Only warn, don't error, if unknown symbol types.
5417 This keeps an old gdb from falling on its face if it sees newly
5418 extended symbol info. Rename init_misc_bunches.
5420 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
5422 * Merge in changes from Per Bothner for DECstations and other
5423 MIPS stuff. The rest is Bothner speaking:
5425 The next message is a merger of Alessando Forin's mips port with
5426 mine. I've tried to use my good if biased judgment to get
5427 the best of both. It *does* need testing.
5429 Some of the changes are general, *not* mips-specific.
5432 Didn't believe in little-endian bit order.
5433 There are still inconsistencies about whether flags
5434 like BITS_BIG_ENDIAN are integer (#if ...) or
5435 boolean (#ifdef ...). I tried to paper over them.
5437 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
5438 Moved some misc_function code that was common to
5439 {dbx,coff,mips}read.c to symtab.c.
5440 In the process, I think I cleaned things up a bit.
5441 At the same time, moved obsavestring and obconcat to symtab.c.
5444 Removed obsolete condense_addl_misc_bunches (use
5445 condense_misc_bunches(1) instead).
5448 Needed to include <sys/dir>, at least on DECstations.
5450 valops.c, mips-tdep.c, tm-mips.h:
5451 Added PUSH_ARGUMENTS macro to support funny argument-pushing
5452 conventions (when STACK_ALIGN is insufficient).
5453 Needed on mips, where doubles need 8-byte alignment,
5454 but ints only need 4.
5457 Removed cruft that was not being used.
5458 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
5461 Print $ before register-names (I think that makes things a little
5463 Never print two instructions, even if one delays.
5464 Removed hex-disassemble set_cmd. (This is not mips-specific,
5465 so I think the argument is whether it is generally worthwhile or not.
5466 I'm inclined to think not, given how easy it is to
5467 convert between radixes in gdb.)
5470 This is basically Alessando's code.
5471 It doesn't use obstacks; I changed it to use obstacks
5472 in a few minor places where using malloc causes a
5473 memory leak. (Probably, more places could/should be changed.)
5474 I added record_misc_function where it was missing.
5475 In symbol_file_command and add_file_command, I tried
5476 to make the code consistent with more recent versions.
5477 Minor sylistic changes in parse_procedure.
5478 Make a .gdbinfo. psuedo-symbol point back to the real
5479 procedure symbol (using the isym field).
5482 This is basically from my port, but with a lot of details
5483 and a number of routines merged in from Alessando's version.
5484 I basically used my code "raw" backtrace (use heuristics
5485 from the actual code, rather than symbol table info) - though
5486 the idea is Alessandro's. I feel my code is a little cleaner
5487 here, particularly in being a little more flexible, such as being
5488 able to handle gcc-produced code (which it now can).
5489 It also doesn't do frame caching (which is not useful
5490 more recent gdb versions).
5491 I also used my code for push_/pop_dummy, more or less.
5492 I tried to incorporate AF's code for testing sigtramp
5493 while backtracing; I probably got it wrong.
5494 Added mips_print_register, which tries to scrunch as much
5495 information as possible on a screen...
5496 Removed the skip-prologue set_cmd. As with hex-disassemble (see
5497 under mips-pinsn.c), I don't see anything mips-specific here,
5498 and I don't see it being all that useful anyway.
5501 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
5502 Use more register names (rather than hard-cases numbers).
5504 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
5506 * Hack up 3.90.11 changes:
5508 * Makefile.dist (depend): parameterize $(GCC).
5509 Add solib.c and solib.o.
5510 (readline): Fix vpath for both absolute or relative SRCDIR.
5512 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
5513 Also, let the part I didn't understand at least compile so
5514 I can test the rest. FIXME.
5516 * dbxread.c: Fix thinko using strcmp.
5517 (init_psymbol_list): declare static.
5518 (partial_symbol_file_open): Comment cleanups better, avoid
5519 cleaning up the string table since the caller will do that.
5520 Move the stat for mod time into symbol_file_command, temporarily.
5521 (There should be a mod time for each symbol file, eventually,
5522 to control its rereading. FIXME.)
5524 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
5525 SunOS, which gives error for shared libs otherwise. (From
5526 Schaefer, probably FIXME needs work for portability.)
5528 * solib.c: Move #include "param.h" to work.
5529 Lowercase all the Uppercase Letters In the Messages.
5530 (find_solib): Clean up inferior_so_name for debug printouts.
5531 Allow no argument, to mean all shared libraries.
5533 * symmisc.c: include param.h to get CLEAR_SOLIB.
5535 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
5537 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
5538 to 3.90.11. ChangeLog entries below are from this.
5540 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5544 * Makefile.dist (HFILES): Add tm-sunos.h.
5546 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5550 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
5552 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
5554 * sparc-opcode.h Added single-operand version of rett.
5556 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5558 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
5559 Put parens around gcc_p in expansion.
5561 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5563 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
5565 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5567 * Changes for Sun shared libraries:
5568 blockframe.c (find_pc_partial_function): If a non-text symbol
5569 is found, set *address = pc - FUNCTION_START_OFFSET.
5570 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
5571 Disable breakpoints instead of giving an error.
5572 source.c (select_source_symtab): Initialize cs_pst.
5573 symmisc.c: Call CLEAR_SOLIB if defined.
5574 symtab.h: Make text{low,high} CORE_ADDR not int.
5575 (psymtab): New field addr.
5577 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
5578 (record_misc_function): Give correct type for N_DATA symbols.
5579 (condense_misc_bunches): do "misc_function_count = j" regardless
5581 Take code which is shared between symbol_file_command and
5582 add_file_command and put it into partial_symbol_file_{open,read}.
5583 Split add_file_command into add_file_command and add_file.
5584 Make psymtab_to_symtab read in the string table if the file
5586 Two new parameters to read_dbx_symtab and start_psymtab.
5587 tm-sunos.h: New file.
5589 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5591 * infcmd.c: Change cont_command to continue_command and "cont"
5594 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5596 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
5598 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
5600 * values.c (USE_STRUCT_CONVENTION): Check for structures of
5601 size 1,2,4,8 rather than size < 8.
5603 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
5604 as necessary, not just once.
5606 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
5608 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5610 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
5612 * tm-news.h: Add CALL_DUMMY_*.
5614 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
5616 * config.gdb: In list_host, list_target, use ${i}, not $i.
5618 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5620 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
5622 * sparc-opcode.h: Change all store floating-point state register
5623 instructions to have the right match & lose fields.
5625 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5627 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
5629 config.gdb: If srcdir != ., create readline directory and
5630 copy a makefile into it.
5632 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
5633 consistency with POSIX.
5635 * breakpoint.c (bpstat_stop_status): Disable watchpoint
5636 when we exit its exp_valid_block.
5638 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
5640 * Makefile.dist: Bump version to 3.91.3.
5642 * Clean up handling of breakpoint commands (somewhat).
5643 Prompted by Tiemann bug report "cont 10" doesn't work any more.
5645 inferior.h: Add breakpoint_proceeded to inferior status struct
5646 and globals; save it and restore it.
5647 (clear_breakpoint_commands): Cleanup, remove old #define.
5649 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
5650 (save_inferior_status, restore_inferior_status): handle it also.
5651 (proceed): Remove earlier code that set breakpoint_proceeded.
5652 It is now set only in clear_proceed_status.
5653 (clear_proceed_status): Cleanup, use bpstat_clear rather
5654 than clear_breakpoint_commands. No callers need the stop_bpstat
5655 between clear_proceed_status and proceed.
5657 infcmd.c: Add breakpoint_proceeded definition and comment.
5658 (cont_command, jump_command, signal_command): Move call to
5659 clear_proceed_status right next to call to proceed.
5661 breakpoint.c (bpstat_do_actions): Avoid clobbering our
5662 caller's argument while running down the chain of breakpoints.
5663 Use new variable "breakpoint_proceeded" to determine when
5664 a command that it executes moves the inferior past the
5666 (bpstat_clear): Handle NULL argument.
5667 (bpstat_clear_actions): Avoid useless call to
5668 breakpoint_auto_delete.
5669 (delete_breakpoint): Clean up bpstat's that are pointing to
5670 the deleted breakpoint from the stop_bpstat chain.
5671 (breakpoint_auto_delete): Simplify.
5673 * Clean up handling of EOF, error on stdin, etc. This was
5674 prompted by a network problem that caused gdb to go into an
5675 infinite loop filling up its malloc'd memory.
5677 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
5678 not clear_breakpoints_commands, which is now gone.
5679 (main): If command_loop returns (e.g. from EOF on stdin), do
5680 a quit_command (looping back to command_loop if quit_command
5681 doesn't really quit).
5682 (command_loop): check result from command_line_input and
5683 exit if it returns NULL, rather than passing the NULL to
5685 (gdb_readline): Free malloc'd result space before returning
5688 * utils.c (query): Handle C-d to mean "yes", just as if the
5689 input was not a terminal. Also avoid infinite loop if EOF
5690 occurs in mid-input-line before newline. This allows
5691 query to be used at EOF on stdin with reasonable results.
5693 * infrun.c (proceed): Set breakpoint_proceeded.
5695 * values.c (value_as_long): Avoid infinite recursion for enums.
5696 (_initialize_values): Fix typo in help msg (kingdon).
5698 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
5699 RL_LIB for linking. This allows -lreadline for linking
5700 and nothing for dependencies, once readline is a real library.
5702 * config.gdb: Jim Kingdon: give useful error message if the
5703 host or target type is not recognized.
5705 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
5706 it just defines it. Dumb, but deal with it.
5708 * Jim Kingdon suggests:
5709 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
5711 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
5713 * Makefile.dist (VERSION): Bump version # to 3.91.2.
5715 * Clean up Bothner's changes.
5717 * blockframe.c (clear_pc_function_cache): New function.
5718 * blockframe.c: remake cache_pc_function_* static.
5719 * dbxread.c (symbol_file_command): remove references to
5720 cache_pc_function_* variables.
5721 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
5722 * printcmd.c: Avoid kludging a global variable (addressprint)
5723 to avoid printing the address of a string twice. Instead,
5724 pass the format letter 's' down low enough that it can be seen
5725 to avoid this problem.
5726 (print_formatted): Pass format arg to value_print.
5727 (restore_addressprint): Remove function.
5728 (do_examine): Avoid hacking addressprint, cleanups and such.
5729 (print_frame_args): Add a comment to a Bothner change.
5730 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
5731 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
5732 to wipe out the values cached in blockframe.c.
5733 * symtab.c (find_method): Add comment saying how big you must
5734 allocate to be "big enough". Per being terse again.
5735 * valprint.c (val_print): Handle format letter "s" to print
5736 strings without addresses. Add comment to vtbl printing code
5737 which casts with wild abandon. Rearrange reference-printing
5739 @0xaddr: value (print w/addressprint)
5740 value (print w/~addressprint)
5741 @0xaddr (parameter lists w/addressprint)
5742 or nothing (parameter lists w/o addressprint)
5744 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
5746 * Merge more changes from Per Bothner:
5748 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
5749 annoying) that I tried to improve it. Here are my suggestions.
5751 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
5754 Do automatic de-reference when taking the address of a reference.
5756 Don't deref_ref when printing parameter lists.
5758 More attempts at treating refernences properly.
5760 In val_print, if deref_ref==0, don't print dangling " = ".
5762 Add COERCE_REF macro, which de-references an REF.
5764 * Merge changes from Per Bothner:
5766 * Fixed (Sony news)-specific configuration problems.
5767 * Fixed other problems with using vanilla pcc and libc (enum problems;
5768 assumption that vsprintf exists).
5769 * Some major speed-ups (finc_pc_partial_function now caches a match;
5770 parsing avoids duplicate symbol_lookup calls).
5771 * Changed handling of baseclasses (no longer use baseclasses field
5772 of struct type, use the first n_baseclasses fields instead).
5773 * Various minor changes/fixes, most C++-related.
5776 Cache the most previous match from find_pc_partial_function.
5777 (Save both low and high ends of matching function's pc range.)
5778 This speeds up the loop of infrun.c:wait_for_inferior quite
5779 a bit, and makes step/next commands much zippier.
5781 Added an enum->int cast (otherwise, some compilers barf).
5783 No longer set baseclass offset to 0, since multiple
5784 inheritance now mostly works.
5785 Added a number of casts, to shut up compiler warnings
5786 (after stabs where made enums, not ints).
5787 When discarding a symbol table (in symbol_file_command),
5788 must clear the cache introduced in blockframe.c.
5789 Don't convert $vtbl_ptr_type to vtbl any more.
5790 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
5791 Mask off sign bit emitted by g++ for virtual table offset.
5792 Set voffset to -1 (not 1) for static member functions.
5794 Changed parsing/lexing of names to avoid doing symbol lookup twice
5795 (once when lexing to determine symbol class, once for real).
5796 Now only call symbol_lookup once. Fields of 'this' win especially big.
5798 Subpress printing addr twice in the case of 'x/s addr'.
5800 lookup_basetype_type is no longer used.
5801 Add find_methods as recursive helper function to decode_line_1.
5802 This allows multiple inheritance to work.
5803 Also, once one or more matches has been found, do not look in
5804 base-classes. (Baseclass methods would be overridden, anyway.)
5806 Removed baseclasses array in struct type.
5807 Instead of using baseclasses[i], use fields[i-1].
5808 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
5809 Changed sign convention of voffset (previous was inconsistent).
5811 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
5813 Used to assume existence of vsprintf. Re-written to not need it
5814 if HAVE_VPRINTF is undefined.
5816 typecmp was too pessimistic. Made it less so.
5818 Don't print space after address.
5819 If vtable points to a misc symbol (with 0 offset), print it,
5820 since that indicates the actual class of the object.
5821 Changed ype_print_derivation_info to use new inheritance
5822 scheme (without baseclasses vector).
5824 In value_primitive_field, fixed some bugs left over from previous set of fixes.
5825 Also, changes needed because TYPE_BASECLASSES were removed.
5827 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
5829 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
5832 If there is no path set, and the symbols don't indicate what directory
5833 a file was compiled in, look in the current directory. But either
5834 a path or a known compilation directory will prevent this.
5837 Three independent bug fixes:
5838 * Remove the #if 0 block that breaks some stuff.
5839 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
5840 adapt gdb to either SunOS 4.0.* or 4.1.
5841 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
5844 Instantiate the class T when looking for methods in it. (Tiemann@sun)
5847 (type_print) Demangle the name being printed.
5848 (type_print_base) Handle botched demangling without coredump (tiemann).
5851 (check_stub_method): Document routine.
5852 (tiemann) fix bug for no-arg functions
5853 Avoid clobbering beyond end of malloc'd storage.
5854 Terminate the argument list properly.
5856 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
5858 * Changes merged by John Gilmore:
5861 In breakpoint_1, use new print_address_symbolic instead
5862 of find_pc_partial_function. (This forces use of assembler-level
5863 addresses, and avoids misleading non-mangled source-level names.)
5865 Generalize ansi argument such that -1 means skip arglist totally.
5866 Removed global variable print_ansi_qualifiers (which made
5867 code non-reentrant), in favor of extra explicit arguments
5868 to internal routines.
5870 Add new helper function print_address_symbolic.
5871 Use find_pc_misc_function instead of find_pc_partial_function
5872 (since we want assembler-level symbols here).
5874 Print unknown function as just "f (...)", not "f (...) (...)".
5875 Use new fputs_demangled explicitly.
5877 Fixed a typing violation (problem: value.h cannot be imported
5878 without renaming many variable in this file).
5879 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
5880 decode_line_1: Moved forward some never-reached code.
5881 Made decode_line_2 skip function prologues correctly.
5883 fputs_filtered should not demangle by default.
5884 Add new fputs_demangled to demangle on demand..
5886 Change value_struct_elt to use value_primitive_field (using recursive
5887 utility function search_struct_field). This allows foo.bar to work
5888 for multiple inheritance (so far only for data fields).
5889 Change check_field in the same way (recursive helper function
5890 to support multiple inheritance).
5891 (Note: there are more of these problems that I haven't fixed.
5892 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
5893 value_of_this: 'this' symbol name is now just "this", note "$this".
5895 Don't print static members.
5896 Avoid printing "members of <type>" if there are none.
5897 Simplified type_print_derivation_info by merging duplicate code.
5898 Remove useless blank lines in type_print_base (ptype command).
5900 Added declaration of new routine value_primitive_field.
5902 Added value_primitive_field which is generalized version of
5903 value_field that can handle multiple inheritance (non-zero offsets etc).
5904 Re-implemented value_field to call value_primitive_field.
5906 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
5908 * infcmd.c -- insert else to avoid 'delete env' coredump when you
5909 delete the whole environment. Karl Berry reported the bug.
5910 * source.c - fix openp to avoid //'s in filenames, which
5911 trigger an Emacs bug causing it to not be able to find files
5912 when running gdb in a window.
5913 * dbxread.c - zap the #if 0 that botches the add-file code.
5914 It seems to work a lot better without all the code commented out.
5916 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
5918 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
5921 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
5923 * Makefile - added a ${CFLAGS} to a couple of entries,
5924 added remote-sa.sparc.c
