1 Thu Nov 7 04:51:19 1991 John Gilmore (gnu at cygnus.com)
3 * tm-*.h: Remove READ_DBX_FORMAT, COFF_FORMAT, and
4 READ_MIPS_FORMAT, which have been unused since BFD. Still
5 remaining is COFF_NO_LONG_FILE_NAMES.
6 * tm-sun3.h, tm-altos.h: Remove detritus accidentally left from
7 function calling code moved to m68k-tdep.c.
9 Wed Nov 6 17:21:59 1991 John Gilmore (gnu at cygnus.com)
11 * coffread.c: Eliminate c_nsyms in favor of c_naux.
12 Complain if no auxents on .bf and .ef FCN symbols, and assume
14 (init_linenos, enter_linenos): Use a sentinel at the end of the
15 read-in linenos, to make for a fast, safe loop-end test.
17 Wed Nov 6 02:54:08 1991 Steve Chamberlain (sac at cygnus.com)
19 * coffread.c (read_coff_symtab): coffread used to rely on the
20 x_sym.x_misc.x_lnsz.x_lnno field giving the # of linnos in a
21 function. Two of the formats I'm using (29k and 88k) don't seem to
22 set it. Ths patch to fcn_last_line and (enter_linenos) is an
23 attempt to use the actual size of the linno table in the file to set
24 the number of linenos to process.
26 Tue Nov 5 22:47:46 1991 Steve Chamberlain (sac at cygnus.com)
28 * Makefile.in: put a - infront of the mv y.tab.c c-exp.tab.c and
29 mv y.tab.c m2-exp.tab.c, so that if bison is used, and the files
30 are created in place, so the mv fails, then the make continues.
32 Tue Nov 5 16:47:47 1991 Per Bothner (bothner at cygnus.com)
34 Add C++ as a separate language.
35 * defs.h (enum language): Add language_cplus.
36 * dwarfread.c (end_symtab): Support language_cplus.
37 * c-exp.y: Add new struct language_defn cplus_language_defn.
38 Don't set c to be the default language (see main.c).
39 * c-exp.y (yylex): Only look for field of this if
40 language is C++. (First difference from C!)
41 * language.c: Add case branches for C++ (currently, all
42 the same as C). Also, add c++ to "usage" note for "set lang".
43 * valprint.c (typedef_print). Add case branches for C++.
44 * main.c (main): New way to set initial language: Look at
45 file extension of psymtab containing main(). (Same as we
46 do for symtabs, but avoid loading the symtab yet.)
47 * symtab.c: New routine find_main_psymtab(), used by main()
48 to set initial language.
49 * symfile.c (allocate_symtab): Move code for mapping file
50 extensions-> languages to new deduce_language_from_filename().
52 Fix a C++ problem when looking for methods in super-classes.
53 There was confusion between base and derived types.
54 * valops.c (value_fn_field): Change function interface.
55 * values.c: Use new value_fn_field interface.
57 Mon Nov 4 10:49:33 1991 Per Bothner (bothner at cygnus.com)
59 * infrun.c: Fixed typo in comment.
60 * utils.c: All the v*fprintf emulation is now in libiberty,
61 so we can get rid of some junk.
62 * xm-sun3os4.h, xm-sun4os4.h, xconfig/decstation, xconfig/i386sco,
63 xconfig/sun3os4, xconfig/sun4os4: Don`t need HAVE_STRSTR any more.
64 * m68k-pinsn.c (print_insn_arg): Support BB/BW/BL
65 type operands, as used by branch instructions.
66 * gmalloc.c: Fix prototype of memcpy.
67 * elfread.c: Comment out register_addr, since it conflicts
68 with the one in coredep.c.
69 * buildsym.h: Remove extern declarations of two functions
70 that are really static in buildsym.c.
71 * tm-mips.h: Add symbolic names for more registers.
72 * mips-xdep.c (store_inferior_registers): Use new register names.
73 * xm-mips.h: Simplify REGISTER_U_ADDR, since it is now
74 only used for core files, not ptrace. Therefore,
75 the KERNEL_U_ADDR hack is no longer needed.
76 The mapping to ptrace number is now in in mips-xdep.c.
77 * mips-xdep.c: Define REGISTER_PTRACE_ADDR (using the
78 mapping from the old REGISTER_U_ADDR), and use it
79 in {fetch,store}_inferior_registers.
80 * mipsread.c: Rename #include ecoff.h to new name coff-mips.h.
81 * mips-tdep.c (mips_push_dummy_frame, mips_pop_frame):
82 Save/restore FP regs correctly (?).
83 * dbxread.c: Remove duplicate define_symbol and type_synonym_name
84 (these had been previously moved to buildsym.c).
85 Hence, define_symbol becomes extern instead of static.
86 * buildsym.c (read_struct_type): Comment out bogus handling
87 of C++ operator methods. Minor hacking of reading of class
88 contexts. Make define_symbol non-static, so dbxread.c can call it.
90 Fri Nov 1 11:05:47 1991 John Gilmore (gnu at cygnus.com)
92 * mipsread.c (read_mips_symtab, read_the_mips_symtab): Use real
93 filename with error messages.
94 * stack.c (frame_select_command): Rename to select_frame_command
95 to avoid "fr" and "fra" having nonunique completions.
96 * symfile.c (sort_symtab_syms): Ignore sort of zero symtab *.
97 (symfile_init): Print file format name when unable to handle it.
98 (free_named_symtabs): Use BLOCKVECTOR rather than obsolete BLOCKLIST.
99 * symmisc.c (free_symtab): Only free linetable if nonzero.
100 * symtab.h: Remove obsolete BLOCKLIST macros.
102 Thu Oct 31 18:12:43 1991 Stu Grossman (grossman at cygnus.com)
104 * infrun.c (wait_for_inferior): another stepi/nexti fix. Ensure
105 that stop_step is 1 at bottom of main loop. I don't know why this
106 needs to be done, but it helps me sleep better at night.
108 Sun Oct 27 18:18:39 1991 Stu Grossman (grossman at cygnus.com)
110 * main.c (initialize_history): Read history after reading all
113 Sun Oct 27 14:09:25 1991 John Gilmore (gnu at cygnus.com)
115 * buildsym.c: Break out initial malloc sizes.
116 (record_line): Record directly in a subfile. Alloc on demand.
117 (compare_line_numbers): Add from xcoffread.c.
118 (end_symtab): New params say whether to sort pendings and
119 linetable. Patch block stabs if defined. Shrink linetable before
120 allocating the symtab.
121 * buildsym.h: Delete line_vector* and prev_line_number. Add
122 global_stabs and file_stabs for xcoffread.
123 * dbxread.c (start_subfile): Move to buildsym. Change above calls.
124 * symtab.h: LINETABLE(symtab) can now be null. Zap LINELIST.
125 * symmisc.c, symtab.c: Cope with null LINETABLEs.
127 * blockframe.c: Pass fromleaf to INIT_EXTRA_FRAME_INFO.
128 * tm-29k.h, tm-88k.h, tm-i960.h, tm-irix3.h, tm-mips.h, tm-pyr.h,
129 tm-sparc.h: Accept fromleaf parameter.
130 * c-exp.y (yyerror): Pass error message if given.
131 * configure.in: Add rs6000 host and target.
132 * inflow.c (new_tty): O_NOCTTY kludge for RS/6000.
133 * symfile.h (entry_point): Add.
135 Sat Oct 26 00:16:32 1991 John Gilmore (gnu at cygus.com)
137 * buildsym.c: New file. Breaks out symbol-table-building routines
138 from dbxread.c, so they can be shared with xcoffread.c.
139 * buildsym.h: New file. Declarations for buildsym.c users.
140 * dbxread.c: Remove large chunks into buildsym.c.
141 * Makefile.in: Add buildsym.c and buildsym.h.
143 * symfile.c (syms_from_bfd): New routine.
144 (add_symbol_file): Call it to do the real work.
145 (syms_from_bfd): Initialize entry_point before calling symfile_init.
146 * symtab.h, symfile.c, coffread.c, mipsread.c, dwarfread.c:
147 Avoid declaring or setting entry_point (symfile.h & symfile.c cope).
149 Fri Oct 25 18:59:32 1991 Per Bothner (bothner at cygnus.com)
151 Various fixes to improve g++ debugging.
152 * symtab.h: Add is_const and is_volatile flags for each method.
153 These are bit fields - take their space from voffset,
154 which shrinks to 30 bits. Since voffset is now a bitfield,
155 make it unsigned for portability. This changes its interpretation
156 slightly: Static methods now have voffset 1 instead of -1,
157 and virtual offsets start at 2, not 1.
158 * symtab.c: Renamed gdb_mangle_typename to gdb_mangle_name,
159 since it now returns an entire magled method name, not just
160 the type part. This avoids some duplication.
161 It also allows us to correctly mangle const and volatile
162 methods (using the new is_const and is_volatile bit fields
164 * valprint.c (type_print_base), values.c (check_stub_method):
165 Simplify by using new gdb_mangle_name.
166 * values.c (value_headof): Fix to correctly handle single
167 inheritance (actually two fixes, either of which suffices).
168 * dbxread.c (read_struct_type): Handle const and volatile
170 * dbxread.c (read_struct_type): Yet one more place where
171 we must handle '\\' continuations.
172 * valprint.c (vtbl_ptr_name): Add final '\0'.
174 Fri Oct 25 16:06:38 1991 Stu Grossman (grossman at cygnus.com)
176 * tm-sparc.h, tm-68k.h (EXTRACT_RETURN_VALUE): fix output of
177 short return values for sparc and 68k. Patch from Paul Eggert.
179 * coffread.c, coredep.c, i386-xdep.c: install patches for
180 SysV/386 3.2 from Mauro DePalma.
182 Fri Oct 25 02:02:13 1991 John Gilmore (gnu at cygnus.com)
184 * core.c (core_file_info), exec.c (exec_file_info): Print file
185 type. Use printf_filtered.
187 * valops.c (value_fetch_lazy): Avoid 0-length fetches.
189 Thu Oct 24 23:06:40 1991 Fred Fish (fnf at cygnus.com)
191 * dwarfread.c: Add casts to remove compiler warnings.
193 * tm-3b1.h, tm-68k.h, tm-altos.h, tm-amix.h, tm-hp300bsd.h,
194 tm-hp300hpux.h, tm-isi.h, tm-news.h, tm-pn.h, tm-sun2.h,
195 tm-sun3.h: Remove locally duplicated code for calling functions
196 in the inferior. The only differences were in the specific trap
197 vectors used and whether or not an fpu was present. These are
198 now handled by appropriate definitions of BPT_VECTOR and
199 HAVE_68881 respectively. Other minor obvious cleanups.
201 * valops.c: Correct a minor misspelling.
203 * utils.c: Remove local BSD/USG hacks that are now in libiberty.
205 * dwarfread.c: Remove prototype for dwarfwarn. Does not work
208 Thu Oct 24 09:33:44 1991 John Gilmore (gnu at cygnus.com)
210 * stack.c (frame_command): Always print. Use new
211 frame_select_command to select a frame without printing.
213 * dwarfread.c: Use <varargs.h>, since <stdarg.h> is not portable.
215 Thu Oct 24 01:32:51 1991 Fred Fish (fnf at cygnus.com)
217 * dwarfread.c: New file for DWARF debugging format support.
219 * elfread.c: New file for ELF object file format support.
221 * procfs.c: New file for SVR4 /proc (process file system) support.
223 * tm-amix.h, xm-amix.h, tconfig/amix, xconfig/amix: New files for
226 * xm-svr4.h, tm-svr4.h: New files for SVR4 support.
228 * xm-m68k.h: New file for host machines with m68k cpu.
230 * Makefile.in: Add elfread.c and dwarfread.c to SFILES_MAINDIR.
231 Add elfread.o and dwarfread.o to OBS.
233 * symfile.h: Add "elf" to list of supported formats in comment.
235 * c-exp.y, defs.h, symtab.h, valprint.c: Add three new builtin
236 types to gdb, builtin_type_long_double, builtin_type_complex, and
237 builtin_type_double_complex. Add and use new TARGET_SHORT_BIT,
238 TARGET_INT_BIT, TARGET_LONG_BIT, TARGET_FLOAT_BIT,
239 TARGET_DOUBLE_BIT, TARGET_LONG_DOUBLE_BIT, TARGET_COMPLEX_BIT, and
240 TARGET_DOUBLE_COMPLEX_BIT, as the sizes in bits of the indicated
241 types on the target machine (ala the existing TARGET_LONG_LONG_BIT).
243 * infrun.c: When using SVR4 /proc interface instead of ptrace(),
244 call proc_set_exec_trap() to setup child to stop at first instruction.
246 * inftarg.c: When using SVR4 /proc interface, call proc_wait()
249 * m68k-tdep.c: Add new routines supply_gregset(), fill_gregset(),
250 supply_fpregset(), and fill_fpregset(), which are machine
251 dependent support routines for SVR4 /proc interface.
253 * utils.c: Add warning_setup() and warning(). Warning() behaves
254 the same as error() except that it returns normally rather than
255 jumping back to command level. Modules that don't want to call
256 warning() for some reason, but want to produce their own warnings,
257 can call warning_setup() to ensure compatibility with the way
258 warning() and error() deal with the terminal.
260 * symtab.c: Make internal errors produce more useful messages.
262 * tm-68k.h: Move code that is duplicated in almost every single
263 m68k based machine's configuration files to this common file.
264 Duplications in the configuration files still need to be removed
267 * infrun.c (child_create_inferior): System V versions must call
268 setpgrp() with no arguments, to comply with prototyping typically
271 * munch: Add support for SVR4 style nm output.
273 * dbxread.c, mipsread.c symmisc.c, symtab.c: Remove the object
274 file specific fields from the partial symbol table structure and
275 replace them with a pointer to private data for each different
276 flavor of object file reader to initialize appropriately.
278 Wed Oct 23 09:38:20 1991 John Gilmore (gnu at cygnus.com)
280 * xconfig/sun[34]os4: Add note about strstr botch on sunos4.0.3c
283 * mipsread.c (fixup_undef_type): New function. If a struct /
284 union / enum is defined in a header file but nowhere else used,
285 (by typedefing, pointer referencing or declaration) the mipsread code
286 builds the complete tree for the structure but leaves its code as
287 TYPE_CODE_UNDEF as it doesn't know what kind of aggregate it is.
288 Guess its type based on the details of the members.
290 Tue Oct 22 18:04:32 1991 Stu Grossman (grossman at cygnus.com)
292 * infrun.c (wait_for_inferior): Check return value from
295 Mon Oct 21 17:47:03 1991 Stu Grossman (grossman at cygnus.com)
297 * infrun.c (wait_for_inferior): fix stepi/nexti that was broken
298 by my last edit to this routine.
300 Mon Oct 21 14:27:43 1991 John Gilmore (gnu at cygnus.com)
302 * tm-sun3.h (FIX_CALL_DUMMY): problem with cross debugging.
303 FIX_CALL_DUMMY does unaligned accesses and/or forgets to byte swap
304 the values before putting them into the dummy code. (From Peter
307 Mon Oct 21 10:04:39 1991 Steve Chamberlain (steve at rtl.cygnus.com)
309 * configure.in: added ebmon target.
311 Wed Oct 16 22:49:58 1991 John Gilmore (gnu at cygnus.com)
315 * Makefile.in: Roll VERSION to 4.2.
316 * README, TODO, WHATS.NEW: Update.
318 * core.c (core_open): Improve error message for bad file.
319 Pass .reg virtual memory address to fetch_core_registers to help
320 it find the registers in the core-file header.
321 * coredep.c (fetch_core_registers): Take new argument, use it,
322 and pass it to register_addr to locate the block of registers.
323 * xm-mips.h: Update KERNEL_U_ADDR for new scheme. Cleanup a bit.
325 * dbxread.c (read_dbx_symtab, process_one_symbol): Handle
326 Sequent N_FN_SEQ like everybody else's N_FN.
328 * main.c: Circumvent SCO cc bug with #if !!defined(USG).
329 * tm-i386v.h: #endif guck.
330 * xconfig/i386*: Remove -Dgetpagesize()=4096 kludge.
331 * xconfig/i386sco: Add HAVE_STRSTR to avoid ANSI bdeath.
332 * xconfig/tahoe: Add REGEX, which seems to be missing.
334 * coredep.c: Add <sys/types.h> for SCOnix.
335 * dbxread.c (read_dbx_symntab): Avoid coredump on malformed file.
336 * printcmd.c (print_formatted): Flush output before disassembly.
338 Tue Oct 15 20:12:32 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
340 * doc/refcard.tex (sec "Working Files"): consistent metavars and
341 other improvements, due to comments by François Pinard
342 (pinard@iro.umontreal.ca)
344 * doc/gdb.texinfo (appendix "Installing GDB"): changes in
345 configure, and improvenets related to Pinard's refcard comments
347 Tue Oct 15 08:45:12 1991 John Gilmore (gnu at cygnus.com)
349 Changes from Fred Fish:
350 * tm-68k.h (FPI_REGNUM): Add.
351 * infrun.c (child_create_inferior): flush stdout and stderr
353 * configure.in: Handle amigados, amix hosts and targets.
354 * inflow.c: Handle TIOCGLTC_BROKEN for Amiga.
357 * values.c (show_convenience): Use printf_filtered.
358 * main.c (define_command): Check result of lookup_command for
360 (echo_command): Use printf_filtered, and force output out.
362 * dbxread.c (read_enum_type): Avoid Modula-2 kludge that breaks C
364 * i387-tdep.c (double_to_i387): Fix typo for double_to_ieee_extended.
365 * utils.c (_initialize_utils): If !ISATTY, don't paginate.
366 * configure.in, tconfig/decstation, xconfig/decstation: Rename
367 dec3100 to decstation.
369 Mon Oct 14 13:37:50 1991 Roland H. Pesch (pesch at cygnus.com)
371 * doc/gdb.texinfo: Catch up to changes recorded here in ChangeLog
372 (nodes Continuing and Stepping; Memory; Targets) clarifications
375 Fri Oct 11 23:27:06 1991 John Gilmore (gnu at cygnus.com)
377 * tm-{irix3,mips,nindy960,pn,symmetry,vx960}.h: Move
378 REGISTER_U_ADDR to corresponding xm- file. Sugg. by Peter Schauer.
380 * symmisc.c (print_partial_symtabs): Add printpsyms debug cmd.
382 * m68k-tdep.c (m68k_push_dummy_frame, m68k_pop_frame): Add
383 generic routines for calling inferior functions.
385 * blockframe.c (inside_main_scope, inside_entry_scope): New.
387 * copying.awk: Filter formfeeds out of copying & warrantee.
388 Make them available as `show copying' and `show warrantee' also.
389 * main.c (print_gnu_advertisement): Advt `show' commands.
391 Thu Oct 10 17:25:47 1991 John Gilmore (gnu at cygnus.com)
393 * mach386-xdep.c: Even when cross-compiling, leave in the
394 core-file reading code.
395 * core.c (get_core_registers): Avoid coredump if no .reg section.
397 Wed Oct 9 17:03:34 1991 John Gilmore (gnu at cygnus.com)
399 * mipsread.c, coffread.c: initialise TYPE_VPTR_FIELDNO to -1.
400 This avoids coredumps under `set print object on' in value_headof
401 (called erroneously by value_from_vtable_info) for `p &struct'
402 or `p *struct'. From Peter Schauer.
404 Mon Oct 7 00:06:52 1991 John Gilmore (gnu at cygnus.com)
406 * Makefile.in: Roll version to 4.1.2.
407 * dbxread.c: Use aout64.h, not a.out.gnu.h. Get external symbol entry
408 size from BFD (but, FIXME, we don't yet read external nlists's and
409 convert them to internal nlists's before handling them -- we still
410 assume they have the same size and alignment.) Use SET_NAMESTRING
412 * exec.c (exec_file_command): Move dead coff-encapsulation code
414 * m88k-tdep.c, m88k-xdep.c: Remove encap test and #inc <a.out.h>.
416 Fri Oct 4 22:30:06 1991 John Gilmore (gnu at cygnus.com)
418 * configure.in, tm-i386v.h, xm-i386v.h: Intel 386 Mach host port.
419 * xm-i386mach.h, mach386-xdep.c, xconfig/i386mach: New files.
421 Fri Oct 4 17:04:31 1991 Per Bothner (bothner at cygnus.com)
423 More patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
424 * mips-xdep.c (store_inferior_registers): Don't try to
425 write the (pseudo) FP.
426 * mipsread.c (parse_partial_symbols): Improved algorithm for
427 setting pst->texthigh.
429 Fri Oct 4 16:47:32 1991 Roland H. Pesch (pesch at cygnus.com)
431 * doc/Makefile: make TEXINPUTS include . everywhere
433 Fri Oct 4 00:35:56 1991 John Gilmore (gnu at cygnus.com)
435 * coffread.c, dbxread.c, symfile.c, symmisc.c, symtab.h: Remove
436 vestiges of typevectors, which were for symsegs and are no longer
437 used. (From a question by Eliot Dresselhaus
438 <dresselh@RFT30.nas.nasa.gov>).
440 Thu Oct 3 09:33:26 1991 John Gilmore (gnu at cygnus.com)
442 * dbxread.c, coffread.c: static-ize functions that were
443 gratuitiously external. (From Fred Fish.)
445 * c-exp.y: sym->class to SYMBOL_CLASS (sym).
447 * dbxread.c (dbx_lookup_type): Keep doubling size of typevector
448 until it is large enough.
450 * dbxread.c (read_type): Handle error case slightly better.
451 Make complaint message not C++-specific.
453 Wed Oct 2 17:21:07 1991 Stu Grossman (grossman at cygnus.com)
455 * infrun.c (wait_for_inferior): Fix step/next so that you only
456 stop at the beginning of a new line. This fixes various problems
457 with for loops, nested if-else's and switch statements.
459 Tue Oct 1 06:33:55 1991 John Gilmore (gnu at cygnus.com)
461 * symtab.c (lookup_symtab_1, lookup_symbol): "fatal" errors
462 between symtabs and psymtabs become ordinary error()s.
464 * dbxread.c (read_dbx_symtab): Relocate end_of_text_addr
465 properly, making "end pc" correct in shared lib psymtabs.
466 (From Guy Harris <guy@auspex.com>.)
468 Mon Sep 30 13:15:31 1991 John Gilmore (gnu at cygnus.com)
470 * dbxread.c: Enable, but soften, const_vol_complaint.
471 (read_dbx_symtab): N_STSYM and N_LCSYM define static vars.
472 Ditto Gould N_NBSTS and N_NBLCS. Also, all types in the psymtab
473 should be file-scope, not global.
474 (read_struct_type): Remove ancient multiple-inheritance warning.
475 (read_range_type): Check base type, complain & patch if undefined.
476 * stack.c (frame_info): Demangle the function name in `info stack'.
479 Sat Sep 28 10:02:33 1991 John Gilmore (gnu at cygnus.com)
481 * eval.c (evaluate_subexp_for_address): Don't use
482 TYPE_POINTER_TYPE directly (it might be zero if this type has
483 never had a pointer created before); use lookup_pointer_type.
484 * symtab.c (lookup_method_type): Arguments were swapped in all
485 callers, so fix it here. I'm amazed this worked at all!
487 Fri Sep 27 18:09:31 1991 John Gilmore (gnu at cygnus.com)
489 * c-exp.y, m2-exp.y: Define more yysymbols that happen to be
490 "bss" rather than "data" symbols, but which still conflict.
493 * coffread.c (coff_symfile_read): Use xmalloc, not malloc.
494 * core.c (core_files_info): Shorten output.
495 * exec.c (exec_files_info): Ditto.
496 (build_section_table): Ignore zero-length sections.
497 * language.c, printcmd.c: Lint.
498 * language.h (get_frame_language): Declare.
499 * saber.suppress: update.
500 * stack.c (find_relative_frame): Remove complex code that was
501 #if 0'd, stick with simple code. Lint.
502 * saber.suppress: Update a bit.
503 * symfile.c (add_symbol_file_command): Add "?" to question.
504 * utils.c (parse_escape): Avoid \a due to bdead compilers.
505 * value.h: Declare typedef_print.
507 * valprint.c (val_print, type_print_base): TYPE_CODE_RANGE less
510 * nindy-tdep.c (nindy_frame_chain_valid): Use lookup_misc_func.
511 (Reported by Mark Peek <mark@imagen.com>.)
513 * solib.c (solib_map_sections): Relocate all sections, even
514 though only the text section's size is tracked. Mark ld_text
515 for eventual elimination as we generalize to N sections.
517 * infrun.c (wait_for_inferior): Don't check if the PC is in a
518 call_dummy if we were stopped by a random signal that is being
519 passed to the program. This produced wierd results when calling
520 functions in the inferior and signals (e.g. SIGALRM) were in use.
522 Tue Sep 24 18:05:30 1991 John Gilmore (gnu at cygnus.com)
524 * infrun.c (IN_SIGTRAMP): Not parenthesized properly.
525 Bugfix from Paul Eggert <eggert@twinsun.com>.
526 * tm-ultra3.h (IN_SIGTRAMP): Ditto.
527 * valprint.c (print_floating): Print 9 digits for IEEE floats.

536 Fri Sep 20 16:10:52 1991 John Gilmore (gnu at cygnus.com)
540 * Makefile.in (VERSION): Set to 4.1.
541 * language.c (set_language_command): Print useful help message,
542 and restore the language string after giving help.
543 * valprint.c (typedef_print): Print typedef in C or M2.
544 * symtab.c (list_symbols): Use it.
545 * main.c (main): Avoid any output before (gdb) prompt when -q.
546 * language.c (set_language_command): Handle errors by restoring
547 the language string to its current state (fix from A. Beers).
548 * doc/gdbint.texinfo: Roll in information from README. Rearrange
549 "how to install" and "how to print the doc" stuff so it drops
551 * configure.in: Rename rtpc CPU to romp to match config.sub.
552 * README, WHATS.NEW, TODO: Update for gdb-4.1.
554 Fri Sep 20 17:39:14 1991 Roland H. Pesch (pesch at cygnus.com)
556 * doc/gdb.texinfo: Updates from ChangeLog. set/show write,
557 autoloading shared libs, copyright etc on GDB startup, clean up $_
558 and $__ index refs, set/show listsize and related updates to list
559 cmd. New host/target configs.
561 Fri Sep 20 15:46:00 1991 Roland H. Pesch (pesch at cygnus.com)
563 * doc/Makefile: generate aux version-no file doc/gdbVN.m4
564 from main Makefile.in version definition
565 doc/gdb.texinfo: use version recorded in doc/gdbVN.m4 for current
567 Makefile.in (setup-to-dist): generate doc/gdbVN.m4
569 * doc/gdb.texinfo: merge new language-switching and lang-specific
572 Fri Sep 20 15:00:57 1991 Per Bothner (bothner at cygnus.com)
574 * mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
575 compilers (which may lack stddef.h).
577 Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com)
579 * dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and
580 N_WARNING are the same except for the N_EXT bit, so just use their
581 values alone, rather than OR-ing them with N_EXT.
583 Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com)
585 * mipsread.c (parse_lines): Deal with negative extended line
588 * c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid
589 global symbol conflicts.
591 Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
593 * .gdbinit: Move 'set complaints' to top, so it runs even in
594 case we aren't debugging GDB.
595 * language.c (_initialize_language): Fix type check and range
596 check documentation strings.
597 * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
598 language.c can use it. (Though language.c should really not be
599 handling warnings/errors the way it does, FIXME.)
600 * symtab.c (lookup_primitive_type): const lint.
602 Bugfix from Peter Schauer:
603 * source.c (lines_to_list): Make signed, to avoid comparison
604 going unsigned and complaining that -3 is too high for 21 lines.
605 * stack.c (lines_to_list): Ditto.
607 Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
609 * Makefile.in (HFILES): Add minimon.h.
610 (VERSION): Roll version number to 4.0.95.
611 (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
612 New rules for building distributions. Normal distribution
613 is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
614 one level up from here; it calls make-proto-gdb.dir to build a
615 directory `proto-gdb' which is an image of the release. The old
616 `gdb.tar.Z' rule still works too.
617 * config.sub, configure: Roll in latest from ..
619 Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
621 * doc/gdbint.texinfo: Reorder contents; reorganize new-host,
622 new-target, and new-config chapters; fix minor typos; come closer
623 to usual GNU markup conventions for @file @samp @code @var.
625 Thu Sep 19 17:04:12 1991 Per Bothner (bothner at cygnus.com)
627 Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
628 * mipsread.c (parse_partial_symbols): Enter the name of all
629 structs/unions... into the psymtab so we can access them if the
630 symtab is not read in.
631 * mips-tdep.c: Remove some unneeded #includes.
632 * xconfig/dec3100: Add HAVE_STRSTR.
634 Thu Sep 19 15:14:23 1991 John Gilmore (gnu at cygnus.com)
636 * Makefile.in: Circumvent Sun Make bug on *-exp.tab.o.
637 * c-exp.y, m2-exp.y: Lint.
638 * m2-exp.y: Avoid using yytname[] which is a Bison-ism.
639 * valprint.c (val_print_fields): Check for stub type.
640 * mipsread.c (_initialize_mipsread): Avoid using
641 builtin_type_void at initialize time.
642 (mipscoff_symfile_read): use it now.
644 Wed Sep 18 15:55:51 1991 John Gilmore (gnu at cygnus.com)
646 Merge multiple-language support, and partial Modula-2 support,
647 from Andrew Beers <beers@cs.buffalo.edu>.
649 * i387-tdep.c: New file, consolidates most 80387 support,
650 and eliminates host dependency on double<->extended conversions.
651 * i386-xdep.c, symm-xdep.c: Remove most 387 support.

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

683 * parse.c: New file with the common code remains of expread.y.
684 * parser-defs.h: New file with common declarations from expread.y.

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

1001 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
1002 calls to hexformat() and hex_to_string(). Format strings without
1003 the leading "0x" were ignored.
1005 depend Updated to take the above into account.
1008 Tue Jun 25 15:27:18 EDT 1991
1010 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
1011 and type_check_t to keep track of the current state of
1012 range and type checking.
1013 main.c Added the variables range_mode, range_check, type_mode,
1014 and type_check to record the current state of range and
1015 type checking. Added initialization code to main().
1016 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
1017 the above variables.
1020 Tue Jun 25 17:57:08 EDT 1991
1022 dbxread.c process_one_symbol() updates the variable (enum language)
1023 source_lang based on the extension of the filename
1024 contained in the N_SO sybmol that started this symtab.
1025 When end_symtab() is called, the value of source_lang is
1026 put into the language field.
1027 stack.c select_frame() sets working_lang (and possibly type_check
1028 and range_check) to the language field of the symtab
1029 associated with the frame that is selected if working_mode
1030 is language_auto. If working_mode is language_manual, a
1031 warning is printed and working_lang is not set.
1032 language.c Added the function set_type_range(), which sets the value of
1033 type_check and range_check (if their modes call for
1034 automatic setting) based on the current value of
1035 working_lang. A non-zero argument will cause the current
1036 settings to be output.
1039 Wed Jun 26 14:51:40 EDT 1991
1041 eval.c Added range checks on assignment.
1042 m2-exp.y Added the grammar for sets to the language. Currently,
1043 these do not do anything except print an error message.
1045 Wed Jun 26 17:01:04 EDT 1991
1047 m2-exp.y Added the ability for parse_number() to parse negative
1048 numbers. A global flag is set upon encountering a unary
1049 minus. This was done to make, for example, 1 parse as a
1050 CARDINAL, and not as an integer, per Wirth's examples in
1051 Programming in Modula-2 ed.4.
1052 valprint.c Added support for "set radix 2" by then setting
1053 output_format to 't'.
1054 eval.c Implemented range checking on subrange types. Added calls
1055 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
1056 Implemented MIN and MAX for ennumerated types. The
1057 minimum value of an ennumerated type is defined by Wirth
1058 as the first identifier, and the maximum as the last.
1059 m2-exp.y Made octal numbers ending with "B" be characters and those
1060 ending with "C" be numbers, per Wirth's book. (p. 34)
1062 Thu Jun 27 14:11:52 EDT 1991
1064 stack.c select_frame() now only sets working_lang, it does not
1065 notify the user. If working_mode is language_manual, then
1066 a warning is issued once.
1067 main.c At the end of each call to execute_command(), working_lang
1068 is checked against the local static (enum language)
1069 current. If they differ and working_mode is
1070 language_auto, the new settings of language, type and
1071 range checking are printed out.
1072 stack.c Modified frame_info() to include the language of the
1073 current frame in the output of "info frame".
1074 language.[ch] Added the function language_str() which returns the name
1075 of the current language.
1077 Fri Jun 28 15:33:14 EDT 1991
1079 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
1080 the language. INCL and DECL currently cause an error,
1081 since sets are not implemented yet. INC and DEC are
1082 implemented as PREINCREMENT/PREDECREMENT with one
1083 argument, and as ASSIGN_MODIFY with two arguments.
1084 eval.c Added type checking to the above cases.
1085 value.h Added not_lval_constant to the lval_type ennumerated type.
1086 not_lval_constant means that the value is a constant
1087 value; that is 3 or 'a' or TRUE, not as in a constant
1088 identifier. This is used to help coerce numbers such as 3
1089 to either signed or unsigned numbers.
1090 valops.c Added the function value_coerce_constants() which coerces
1091 constant integers as following: if one is a constant and
1092 the other is not, the constant's type is set to the type
1093 of the other argument. If both are constants and one is
1094 signed, the other is converted to a signed constant.
1096 Sat Jun 29 17:26:29 EDT 1991
1098 valarith.c Added a better range checker. It now checks range
1099 (successfully) on integral operations [+-] (signed and
1100 unsigned) for any C sized type. Still does not work well
1101 for multiplication.)
1102 int_in_size() returns an integer that is coerced to fit into
1103 specified number of bytes.
1105 Mon Jul 1 13:04:14 EDT 1991
1107 language.[ch] Added the function binop_result_type(), which returns the
1108 builtin (struct type *) type that would be the result of a
1109 binop on the two values V1 and V2.
1111 Wed Jul 3 19:22:53 EDT 1991
1113 source.c Extended source_info() to include the source language in
1114 the output from "info source".
1116 Fri Jul 5 13:48:52 EDT 1991
1118 utils.c Moved the support functions for the GDB set/show commands
1119 dealing with language into language.c.
1120 language.c Added the function language_info(), which displays info
1121 about the current working language, type and range check
1122 settings. Called via the GDB command "info language".
1123 Added an initialization routine _initialize_language(),
1124 that sets defaults for the language, type and range
1125 variables and sets up the new GDB commands.
1126 main.c Language setup moved to language.c.
1129 Mon Jul 8 10:10:22 EDT 1991
1131 valarith.c Debugged the range checker for arithmetic. Still does not
1132 work for multiplication very well.
1134 Mon Jul 8 12:40:37 EDT 1991
1136 language.[ch] Added the function value_true() which returns non-zero if
1137 its argument represents a boolean true value.
1138 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
1139 check the truth of an expression.
1141 Thu Jul 11 12:51:34 EDT 1991
1143 language.[ch] Added the predicate structured_type(), which returns
1144 non-zero if the argument is a structured type.
1145 Added the predicate pointer_type(), which returns non-zero
1146 if the argument is a pointer type.
1147 eval.c Added the ability to do addition and substraction on
1148 pointers and integers. This case simply bypasses the
1151 Thu Jul 11 14:41:42 EDT 1991
1154 Added the symbol N_DEFD (0x4a) which is a definition
1155 module dependency that is used by the GNU Modula-2
1156 compiler and the linker. It is not important to GDB,
1157 except that [dbx|coff|mips]read.c should ignore these
1160 Fri Jul 12 16:07:00 EDT 1991
1162 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
1163 0 in val_print(). Also added statements to the else part
1164 to coerce type (argument to val_print) to a pointer type
1165 if it is an "array of unspecified length".
1166 valops.c Added the function value_m2_string(), which returns a
1167 (value) value which is a constant string, whose type is
1168 (ARRAY [0..n] OF CHAR). The length field of the type
1169 structure is set to zero, so it will be interpreted as an
1170 "array of unspecified length".
1171 stack.c Moved the language/frame mismatch check to
1172 main.c:execute_command().
1173 main.c The working language is recorded each time
1174 execute_command() is executed. If working lang has
1175 changed during its execution, then the new
1176 language/type/range info is printed out for the user. If
1177 the working language does not match the language of the
1178 frame, a warning is issued.
1180 Sat Jul 13 16:16:39 EDT 1991
1182 eval.c Moved all the type-checking stuff for operators to
1183 language.[ch] language.c. This is so we can keep language-specific
1184 stuff (like for what type operators are defined) in
1186 language.[ch] Added the function binop_type_check(), which checks to see
1187 if its two (value) arguments are type-compatible with its
1188 opcode argument. The opcode should represent an operation
1189 involving an operator. Also added the macro function
1190 unop_type_check, which calls binop_type_check with a
1191 NULL second argument.
1192 expprint.c Added Modula-2 operators to the op_print_tab, so info
1193 expression.h break works correctly. Also added "op_string", which
1194 returns the string corresponding to the (enum exp_opcode)
1195 opcode that is its argument.
1198 Sat Jul 13 18:26:18 EDT 1991
1200 coffread.c Added code to record the type of function arguments with
1201 each paricular function. Code is very similar to that
1203 dbxread.c Moved add_param_to_type() to symtab.c
1204 symtab.[ch] Added function add_param_to_type() from dbxread.c
1206 *** NOTE: The above additions have not been tested.
1208 Mon Jul 15 12:50:47 EDT 1991
1210 langauge.[ch] Added the functions type_error and range_error, which work
1211 like error() except if the type/range mode is set to
1212 *_mode_warn, then they do not do a return_to_top_level(),
1213 but merely print a warning.
1214 Also changed [set|show]_[type|range]_command() to support
1215 the new "warn" feature.
1217 Thu Jul 18 17:50:54 EDT 1991
1219 mipsread.c Added code to record the type of function arguments with
1220 each particular function. Code is very similar to that
1223 *** NOTE: The above additions have not been tested.
1225 Fri Jul 19 11:19:10 EDT 1991
1227 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
1228 UMIN_OF_SIZE, which when given a size of a numeric type,
1229 return the maximum and minimum value it can hold. UMAX...
1230 and UMIN... return the result for unsigned types.
1231 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
1232 struct types. They call above macros.
1233 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
1234 avoid a name conlict with the above.
1235 c-exp.y Added range checking on numeric constants in
1236 parse_number() for completeness.
1237 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
1238 return 0 if working_lang is not language_c.
1240 Thu Aug 8 14:17:22 EDT 1991
1244 breakpoint.c Documentation strings of some commands changed to
1245 eliminate the references to the C language where
1248 Tue Aug 13 15:48:03 EDT 1991
1250 m2-exp.y Added qualified identifiers to the grammar. The semantics
1251 are slightly different from those of the GDB operator ::
1253 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
1254 type_exp, where type_exp is any valid type expression.
1256 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
1257 printcmd.c Modified ptype_command() so it actually parses the input
1258 (necessary for type expressions with scope qualifiers).
1259 Added the function ptype_eval() which expects an
1260 expression composed of one OP_TYPE element.
1261 *.[ch] Replaced all occurences of parse_c_expression with
1263 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
1265 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
1267 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
1269 Small fixes from Peter Schauer:
1271 * infrun.c (child_attach): Lint.
1272 * solib.c (find_solib): Handle shared libs version 2.
1274 Small fixes from David Wood:
1276 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
1280 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
1281 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
1283 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
1284 chars_per_line is at maximum (user typed `set width 0'). Fix
1285 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
1287 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
1289 * coredep.c: include ptrace.h where necessary.
1290 * mipsread.c(parse_lines): fix unsigned char problem that was
1291 messing up line numbers on SGI's and possibly other MIPS based
1293 * infrun.c (child_create_inferior): use better test to check
1294 return val from setpgrp().
1295 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
1296 for sgi/irix support.
1298 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
1300 * mipsread.c (parse_symbol): Put non-static procedures
1301 in the global block.
1303 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
1305 Patch together `text_start' and `text_end' for 29K port.
1307 * exec.c (exec_command): If NEED_TEXT_START_END, define the
1308 variables and set them based on the exec file.
1309 * am29k-tdep.c: declare text_start.
1310 * valops.c (call_function_by_hand): declare text_end.
1312 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
1313 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
1314 because machines that do this will also have to know to
1315 set NEED_TEXT_START_END. Besides, it was a redundant way to
1317 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
1318 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
1319 NEED_TEXT_START_END.
1321 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
1323 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
1325 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
1326 Pass MUNCH_DEFINE to munch whenever we run it.
1327 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
1328 format string; use 0x%x instead.
1329 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
1330 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
1331 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
1332 * inflow.c: Handle `short' process group IDs.
1333 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
1334 and check for ptrace errors.
1335 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
1336 (coff_symfile_init): Initialize text_bfd_scnum.
1337 (read_coff_symtab): Use it to find the text [and absolute?] sections.
1338 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
1339 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
1340 Merge target arm case with other "easy" cases. Add target
1341 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
1342 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
1344 * minimon.h, remote-adapt.c, remote-mm.c: Add.
1345 * munch: Cope with RT/PC putting fns in data segment.
1346 Restore ability to override `nm' by specifying MUNCH_NM.
1347 * xconfig/rtbsd, xconfig/ultra3: New host systems.
1348 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
1349 and remote-adapt. Remove encapsulated coff #define's (the
1350 support should go in BFD, and gdb shouldn't know or care).
1351 * tconfig/a29k-kern: Same, but for remote kernel debugging.
1352 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
1353 * tm-29k.h: Update BADMAG (though it should go away).
1354 Allow the register definitions to be overridden in another
1355 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
1356 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
1357 DUMMY_SAVE_GR96, for handling kernel calling conventions
1358 that use GR64+ rather than GR96+.
1359 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
1360 remote debugging of Ultra3 kernel. Includes tm-29k.h and
1361 overrides various things.
1363 * remote-mm.c (mm_attach, mm_wait): Handle attach like
1364 child_attach does, making a clean stop in the newly attached
1366 * remote-eb.c: Lint.
1368 * coffread.c: Make coffread independent of any particular
1369 variant of COFF. Avoid #include-ing any particular one except
1370 internalcoff.h. BFD now passes key values for symbol reading
1371 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
1372 and the symbol masks and shifts); use them.
1373 Remove obsolete end_of_text_addr.
1375 * exec.c: Remove unused include files.
1377 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1379 * Makefile.in (documentation targets): Pass $(M4).
1380 Bugfix from eggert@twinsun.com (Paul Eggert).
1382 * stack.c (down_silently_command): Check for stack existence.
1384 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1386 * Makefile.in (VERSION): Update to 4.0.3.
1388 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1390 * core.c (core_file_command): Print frame at coredump with
1391 its level number, by calling print_stack_frame.
1392 * frame.h: Add selected_frame_level, print_stack_frame.
1393 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
1394 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
1395 Change print_sel_frame and print_selected_frame callers to
1398 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
1399 * symfile.c (free_named_symtabs): Ditto.
1400 * main.c (main): wrap_here needs an arg.
1401 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
1402 (solib_add): Avoid noise.
1403 (solib_create_inferior_hook): Lint.
1404 (sharedlibrary_command): Move dont_repeat to here.
1405 * utils.c (error): Call wrap_here to force buffered output.
1407 Small patches from Peter Schauer:
1409 * coffread.c (start_symtab): Free any existing line_vector before
1411 (read_coff_symtab): Ditto for type_vector.
1413 * source.c (lines_to_list): New variable, replacing function.
1414 (all uses): Use as variable.
1415 (_initialize_source): Add 'set listsize' and 'show listsize'.
1416 * utils.c (lines_to_list): Remove function.
1417 * stack.c (print_frame_info): Use as variable.
1418 * defs.h (lines_to_list): Remove declaration.
1420 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1422 * breakpoint.c (insert_breakpoints): Restore warning about
1423 the program might be running in another process, but only for
1424 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
1425 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
1427 * utils.c (error): if error_pre_print is set, print the string
1429 * main.c (main, print_gnu_advertisement, print_gdb_version):
1430 Reformat legalese so it always prints, but acts as an "I'm here"
1431 message while symbols are being read. If any errors occur,
1432 print a few newlines to set off the message and start it at the
1433 left margin. Remove mention of "help" command, and don't yak
1434 about symbol reading.
1435 (catch_errors): Error string is now printed first in case of
1437 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
1438 suggest the "help" command.
1440 * Makefile.in (VERSION): Set to 4.0.2.
1442 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
1444 * .gdbinit: Remove useless "rr" command. Set complaints
1445 to 1 for people debugging gdb.
1447 * breakpoint.c, remote-vx.c: Reword strings printed by
1448 catch_errors callers.
1450 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
1452 * WHATS.NEW: "history write -> history save". Doc "write on/off".
1453 (Fix from kenc@viewlogic.com.)
1455 Fix some infrastructure to be able to cope with host and target
1456 machines with different sized basic types (ints, ptrs, etc).
1457 (Idea from pierre@la.tce.com (Pierre Willard).)
1459 * values.c (value_from_longest): Rename from value_from_long.
1460 Handle pointer types as well as integers, so that targets with
1461 different pointer sizes from the host can be accomodated.
1462 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
1463 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
1464 uses of value_from_long to value_from_longest.
1465 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
1466 the correct pointer type to value_from_long{est}.
1468 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
1470 * remote-vx.c: Remove obsolete code for calling functions via
1471 vxworks kludge interface (it referenced value_from_long).
1473 * valops.c (value_string): Find malloc with lookup_misc_func, not
1476 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1478 Make writing to files work properly. (Fixes to BFD are also needed.)
1480 * core.c (core_open): Open file ourselves, read or r/w, depending on
1481 write_files. Use bfd_fdopenr.
1482 * gdbcore.h (write_files): New variable.
1483 * exec.c (write_files): Define variable, add set&show for it.
1484 (exec_file_command): Use write_files to open for read or r/write.
1486 Make shared library reading happen automatically. These changes
1487 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
1489 * inferior.h (stop_soon_quietly): Add to exported variables.
1490 * infrun.c (child_create_inferior): call solib hook, if defined.
1491 (child_attach): call solib hook, if defined.
1492 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
1493 (find_solib): Use lookup_misc_func rather than hand-rolled.
1494 (symbol_add_stub): New stub for catch_errors.
1495 (solib_add): Avoid output if !from_tty. Catch errors rather
1496 than just calling symbol_file_add and bombing.
1497 (solib_create_inferior_hook): Interface with the target process
1498 to let it read and alloc shared libs, then figure out what it did.
1500 * core.c (validate_files): Fix typo, soften warning.
1501 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
1503 * utils.c (fputs_demangled): Avoid duplicate printing if
1504 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
1506 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
1507 (Fix from pierre@la.tce.com (Pierre Willard).)
1509 * main.c (catch_errors): Change argument to a char * from an int,
1510 since a char * can point to a struct full of glop, but an int
1511 is not guaranteed to be able to hold a pointer.
1512 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
1513 breakpoint_re_set_one, breakpoint_re_set): Adapt.
1514 * core.c (core_open, solib_add_stub): Adapt.
1515 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
1517 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1519 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
1520 by adding .NOEXPORT target.
1522 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1526 * Makefile.in (VERSION): Roll to 4.0.
1527 (gdb.tar.Z): Make refcard.ps as well, for shipment.
1529 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1531 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
1534 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
1537 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
1539 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
1540 reflect above name change
1542 * WHATS.NEW: correct pointer to refcard.
1544 * doc/gdb.texinfo: update New Features, Installing
1546 * doc/gdbint.texinfo: add short description of configure +template
1548 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1550 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
1552 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
1554 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
1555 tar file, add dependencies for referenced doc files.
1557 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
1559 * coffread.c, symfile.c, stack.c: saberized.
1561 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1563 * doc/refcard.tex: permuted Essential Commands sec
1565 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
1567 set/show symbol-reloading
1568 default set complaints 0
1570 RET-repeat disabled after prompted long displays
1571 processID (attach) interpretation of 2nd GDB cmdline arg
1573 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
1575 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
1576 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
1577 breakpoint.c, main.c: lint.
1579 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1581 Install new configuration scheme for GDB and friends.
1583 * config.sub: Translate ordinary names to three-part names.
1584 * configure: Use three-part names internally.
1585 * configure.in: Translate three-part names to filenames.
1587 * README, WHATS.NEW: Update for gdb-4.0.
1588 * Makefile.in: Roll VERSION to 3.99.
1590 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
1592 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
1593 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
1594 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
1595 to single structures rather than arrays; when passing
1596 their address, use &. This avoids trouble with bdead compilers.
1597 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
1598 instead. This avoids portability headaches.
1599 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
1601 * source.c (open_source_file): Avoid ANSI const bdeath by
1602 skipping declaration and then casting result value.
1603 * tm-hp300bsd.h: Clarify comment.
1604 * utils.c (strstr): Result is const char *; ANSI bdeath.
1605 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
1606 since system include file defines it differently from "defs.h",
1607 though the two are equivalent for our purposes.
1608 * tconfig/hp300bsd: Add m68k-tdep.o.
1610 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1612 * tconfig/sun*4: Remove warnings about system assembler.
1614 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1616 * mcheck.c: Avoid warning about undeclared abort fn.
1617 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
1618 it causes recursive calls to error() when used in cleanups.
1619 To do so requires that we make it a function, so we do.
1620 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
1621 * utils.c (do_cleanups): Remove the current cleanup from the
1622 chain *before* calling it, in case error() is called from it.
1623 The result won't be pretty, but won't be an infinite loop either.
1625 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
1627 * dbxread.c (read_struct_type): Grok anon structs for C++.
1628 (vb_name, vptr_name): Null terminate these strings.
1630 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1632 Minor bug fixes from BSD Net2 gdb:
1634 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
1635 returns 0, there is no previous frame.
1636 * breakpoint.c (commands_command): If !from_tty, don't call
1637 input_from_terminal_p().
1638 * dbxread.c (record_misc_function): Speed up slightly.
1639 (compare_psymbols): Ditto.
1640 * infcmd.c (do_registers_info): Take a second argument to
1641 determine whether to print float registers. "info registers"
1642 does not do so anymore. "info all-registers" does, now.
1643 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
1645 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
1646 * inflow.c (initialize_inflow): Set tflags_ours correctly.
1650 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
1651 executing_breakpoint_commands if we are interrupted by error.
1652 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
1653 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
1654 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
1655 catch_errors() so we can setup the frame regardless of whether
1656 the shared libs work.
1657 * ieee-float.c (double_to_ieee_extended): Get exponent from
1658 right place in little-endian systems. From John Carey.
1660 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1662 * main.c: Remove unused terminating_signals and catch_termination().
1663 (long_options): Terminate with a zero element.
1664 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
1665 (gdb_readline): Make call-compatible with readline.
1666 (init_signals): Improve comments re vfork vs. signal.
1668 * utils.c (prompt_for_continue): Use new gdb_readline().
1669 If we prompt for continuation, we don't let CR repeat the previous
1670 command, once we get back to a prompt. It's too easy to keep
1671 hitting CR, expecting "--more--" prompts, and have some long
1672 command start repeating on you.
1674 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1676 * blockframe.c (frameless_look_for_prologue): Speed up by
1677 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
1678 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
1679 Define two variants, one faster.
1680 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
1681 and return zero, rather than giving an error.
1682 (setup_arbitrary_frame): Initialize the PC in the new frame.
1683 (skip_prologue): Add a second arg saying whether we're just
1684 checking for a frameless function or not.
1686 * core.c (core_open, core_close, core_xfer_memory): Move
1687 section table pointers and bfd* into the target_ops.
1688 (core_open): Allow errors in shared lib reading, etc.
1689 (core_files_info): Describe shared library sections.
1691 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
1692 exec_files_info, set_section_command): Move section table
1693 pointers and bfd* into the target_ops.
1694 (add_to_section_table): Add BFD to section table.
1696 * target.c (target_xfer_memory, target_info): Pass target to
1697 xfer_memory and target_info functions.
1700 * gdbcore.h: Move struct section_table.
1701 * target.h: New home of struct section_table.
1703 * solib.c (solib_add): New argument is the target_ops whose
1704 section list is to be added to, if any. Reallocate the
1705 sections in that target to add any that come from shared libs.
1706 (throughout) so_sections renamed to sections.
1707 (solib_xfer_memory): Deleted.
1708 * tm-sunos.h (SOLIB_ADD): Add target argument.
1709 (SOLIB_XFER_MEMORY): Delete.
1711 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1712 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
1713 from target_ops. It's the same on all targets. Add two section
1714 pointers to target_ops.
1716 * stack.c (find_relative_frame): Dump ancient algorithm for
1717 "down", just use handy "next" pointers.
1718 (frame_command): Don't error if there is no stack; let user
1721 * inflow.c (new_tty_prefork, new_tty): New prefork routine
1722 modifies static state in the parent process; new_tty itself
1723 runs in the child and modifies the child's file descriptors
1724 to match the saved static state.
1725 * infrun.c (child_create_inferior): Call new_tty_prefork,
1728 * infptrace.c (child_xfer_memory): Add ignored target arg.
1729 * remote-eb.c (eb_xfer_inferior_memory): ''
1730 * remote-nindy.c (nindy_xfer_inferior_memory): ''
1731 * remote-vx.c (vx_xfer_memory): ''
1732 * remote.c (remote_xfer_memory): ''. Rename from
1733 remote_xfer_inferior_memory.
1735 * main.c (main): Only try to attach "corefile" argument if
1736 it starts with a digit.
1738 * symfile.c (symbol_reloading): New "set/show" variable.
1739 (symbol_file_add): Shorten message about symbol reading.
1740 (add_symbol_file_command): Merge with add_syms_addr_command,
1741 since this should work on all targets now.
1742 (stop_whining): Default to zero, to shut up complaints
1743 about bad symbol tables on many systems.
1744 (free_named_symtabs): Just exit unless symbol_reloading.
1746 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
1747 and add comment explaining shared library screw.
1749 * source.c: #if defined => #ifdef.
1751 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1753 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
1755 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1757 * doc/rdl-apps.texinfo: provide default readline-appendix finder
1758 (doc/Makefile knows how to make one for local config)
1760 * Makefile.in: use doc/Makefile for doc targets
1762 * doc/Makefile: GDB documentation now has its own Makefile
1763 doc/refcard.tex: renamed from "gdbrc.tex"
1764 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
1765 doc/gdbint.texinfo: add markup in "Cleanups" chapter
1768 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1770 * values.c (baseclass_addr): When reading target memory, use the
1771 length of the basetype, not the upper type. We've only malloc'd
1772 enough space for the basetype, leading to errors in free().
1774 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
1775 ends up as a function specially, since we know the actual type of
1776 the pointed-to address. This (somewhat) fixes display of
1777 expressions that include misc_function_vector names. Try `cond 1
1778 !strcmp("a","b")' then `i b'.
1780 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
1781 The child can be proceeded from inside wait_for_inferior in
1782 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
1783 getting skipped in that case.
1785 * expprint.c (print_subexp): Use filtered output, since the
1786 subroutines we call use it, otherwise the output is horribly
1787 mangled, since output of wrappable stuff comes out late.
1789 * Makefile.in: Bump VERSION to 3.98.1
1791 * infrun.c (child_create_process): Use execlp to find the
1792 shell to exec our target program. This requires some fiddling
1793 with `environ' since there is no execlpe().
1795 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1797 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
1798 Minor rearrangement of refcard permits two new make targets--
1799 gdbrc.dvi DVI output for refcard, using CM fonts
1800 gdbrc.ps PostScript refcard, using PS fonts
1802 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1806 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
1807 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
1809 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1811 * doc/gdb.texinfo: last changes for release.
1812 Minor typo and formatting fixes; incorporated most fixes remaining from
1813 filed mail commenting on earlier drafts.
1815 Added warnings: pipes don't work in run command;
1816 conditions are converse of assertions;
1817 step over fn without debug info goes to next fn;
1818 vars may have "wrong" values near fn entrance, exit
1820 Added example from Kingston on printing repeated nonadjacent values
1822 Added explicit mention that in Emacs gdb mode C-c and C-z are like
1823 shell mode for signals
1825 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
1826 doesn't sound so much like its parent "Stopping and Continuing"; also
1827 moved entries on continue to top of section, so they don't get lost.
1829 Improved installation directions in appendix, added manual formatting
1832 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1834 * configure.in: Remove xm.h and tm.h even if we aren't linking
1835 new ones, so "./configure sun4; ./configure none" does the right
1836 thing. Assume that alldeps.mak and depend are already built in
1837 srcdir, and avoid running "make" (particularly "make depend",
1838 which involves "gcc") from inside configure. Build Makefile
1839 directly rather than building Makefile.conf first.
1840 * configure: Regenerate with above changes.
1841 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
1842 to 3.98. Revise gdb.tar.Z procedure to produce a file
1843 called gdb-$(VERSION).tar.Z but which unpacks into a
1844 directory called "gdb". Move non-source files out of
1845 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
1846 (depend): Don't try to do "gcc expread.y".
1847 (expread.o): Update dependencies by hand.
1849 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1852 Fixed a variety of small typos that prevented info from formatting
1853 cleanly; altered too-long heading for GPL Appendix, as discussed
1854 w/RMS; Changed date on cover to July 91.
1856 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1859 (1) Applied some fixes due to comments from Larry Breed (easier ones
1860 through chapsec 5.2)
1861 (2) Eliminated use of @footnote---had my doubts about it anyways, and
1862 it's broken in latest texinfo
1863 (3) Introduced *some* use of [] for optional arguments, where
1864 explanation is not simpler by listing cmd w arg and cmd w/out arg
1865 separately. Still not using @deffn.
1866 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
1867 couple of headings are too long. Need patches to texinfo or revision
1870 * Partial update to README (which still needs work for this
1871 release!): (1) use of configure corrected for new script,
1872 (2) "make gdb.dvi" and "make gdb.info" mentioned.
1874 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
1876 * symtab.c (lookup_symbol): Don't complain right off about
1877 no debug symbols; use the misc function vector first.
1878 (list_symbols): Use misc function vector to find symbols
1879 that don't have debug info, and print them.
1880 (find_pc_symtab): Temporarily avoid fatal() when psymtab
1881 PC range doesn't match symtab PC range, as it does on the
1882 MIPS because our symtab reading isn't perfect.
1884 * dbxread.c (dbx_symfile_read): Make warning about
1885 "no debug symbols" slightly nicer.
1887 * source.c (select_source_symtab): If "main" symbol exists,
1888 but decode_line_spec can't find line info, don't just return
1889 a zero; try other source symtabs or give an error.
1891 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
1892 their low addresses first, then rip through fixing high addrs.
1894 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
1895 <runene@ifi.uio.no>.
1896 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
1898 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1900 * Minor, mostly mechanical, cleanup of doc subdir for clean
1901 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
1902 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
1904 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
1906 Mostly MIPS and general symbol-reading fixups.
1908 * doc/gdbint.texinfo: Add documentation on symbol-reading
1911 * mipsread.c: Remove kludges around #include "ecoff.h".
1912 Remove redefinitions of a_magic, etc, no longer used.
1913 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
1914 Fix global overview comments to match symfile.c protocol.
1915 (mipscoff_new_init): Eliminate cur_hdr if we have one.
1916 (mipscoff_symfile_read): Eliminate unused code. Avoid
1917 sorting all the symtabs, when all we have read here is psymtabs.
1918 The symtabs are sorted as they are created anyway. Tell
1919 condense_misc_bunches whether we're mainline.
1920 (psymtab_to_symtab_1): Pass filename when recursing, to make
1921 stack trace more informative.
1922 (parse_partial_symbols): Assume cur_hdr as argument.
1923 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
1924 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
1925 the TYPE_NAME of char *, since that's done in symfile.c.
1926 (free_numargs, parse_symbol, add_symbol, add_block,
1927 shrink_linetable): Declare these fns void.
1928 (upgrade_type): Convert tree of if's to switch. Clean up
1929 bogus "off == 0" handling with a complaint. Avoid setting
1930 field bitpos and bitsize of array with lower and upper bounds.
1931 Check specified bitsize of elements against their actual type's
1932 bitsize, and complain if different. Complain about unknown
1934 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
1935 (psymtab_to_symtab_1): Print names of subsidiary files that
1936 are being read in. FIXME, we read far too many files. This code
1937 is not the problem, the problem is in parse_fdr where the psymtabs
1939 (cross_ref): Result should indicate that we used one aux entry
1940 normally, or two if we encountered a "next" entry. This used
1941 to leave the caller pointing at the wrong aux entry.
1942 (add_symbol): If overflowed cur_block, reallocate it larger,
1943 chase all pointers to it, and complain(), rather than clobber memory.
1944 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
1945 (new_field): Only allocate one field initially, not two.
1946 Pull ++ out of macro argument. Simplify.
1947 (_initialize_mipsread): Avoid initialization of importd
1948 global_psymbols and static_psymbols.
1950 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
1951 to properly set pst->symtab; avoid searching for it.
1952 (symfile_fns): Improve comments, add a FIXME.
1953 * dbxread.c: Update comments to reflect symfile protocol.
1954 (read_ofile_symtab, end_symtab): Return the symtab.
1955 (psymtab_to_symtab_1): Set pst->symtab.
1957 * coffread.c (coff_symfile_read): tell condense_misc_bunches
1958 whether we're mainline.
1960 * symfile.h (sym_fns): Remove unused sym_discard member.
1961 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
1963 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
1964 the environment variable is not.
1965 * infcmd.c (finish_command): Use filtered printfs.
1966 * cplus-dem.c: Add struct tags to a few unnamed structs.
1967 * valops.c (value_coerce_array): Improve comments.
1968 * valprint.c (type_print_varspec_suffix): Print array size only
1969 if greater than zero.
1970 * m88k-tdep.c: Shift some lines left by one space, that had
1971 apparently been trashed at some point.
1972 * TODO: More things to do, a few got done.
1974 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1976 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
1977 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
1979 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
1980 * expread.y, findvar.c, symmisc.c: Ditto.
1981 * printcmd.c (address_info): Update printed forms of LOC_
1982 symbols. Elim LOC_EXTERNAL.
1983 (print_frame_args): Keep track of param stack offsets before
1984 re-looking up to find the local register param is kept in.
1986 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
1987 Further integration of mipsread into gdb. Eliminate unused
1988 routines, duplicate declarations. Handle static symbols in
1989 psymtabs as well as external symbols. When reading symtabs,
1990 insert symbols into the correct block (global, static, or a local
1992 (read_mips_symtab, parse_partial_symbols): Don't pass useless
1994 (mipscoff_symfile_read): Don't call select_source_symtab.
1995 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
1996 rather than SYMBOL_VALUE.
1997 (parse_external): Comment clobbering of top_stack.
1998 (parse_partial_symbols): Update comments. Allocate and parse
1999 static symbols as well as external symbols. FIXME, enum values
2000 are not handled in this pass, but should be. Inline new_psymbol.
2001 Use SYMBOL_VALUE_ADDRESS.
2002 (psymtab_to_symtab_1): Read symbols into global static block
2003 by default (until enter some function's local block context).
2004 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
2005 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
2007 * source.c (select_source_symtab): Select a source symtab
2008 from either the symtabs or, failing that, the psymtabs.
2009 (list_command): Update error message.
2010 (forward_search_command, reverse_search_command): Use getc, not
2011 fgetc, for speed. FIXME, add comment about buffers that die if
2012 overrun by long line.
2014 * values.c (unpack_field_as_long, modify_field): Avoid shifting
2015 by an entire word, which is not portable, if we have a 32-bit
2016 field. (Code in dbxread.c already turns such bitfields, if
2017 aligned, into ordinary ints, but fixing this will help for other
2018 symbol formats and for future changes.)
2019 * core.c (core_open): Handle ANSI const brain death.
2020 * utils.c (vprintf): Fix varargs typo.
2022 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
2024 * findvar.c (find_var_value): Handle &function better.
2025 * TODO: Document work needed on &fn and &array.
2026 * printcmd.c (print_address_symbolic): New arg is the prefix
2027 to print if a name is printed.
2028 (print_address_demangle): Honor "set print address" now.
2029 Use new arg above to improve spacing of output.
2030 * valprint.c (val_print): When printing function pointers,
2031 print symbolic form too.
2032 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
2034 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2036 * core.c (memory_error): Reword error msg to mislead less.
2038 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
2040 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
2041 parse_partial_symbols): Use newer BFD internals (external_filehdr
2042 and external_aouthdr), byte-swap the fields that we care about
2043 before using them, and make the file header data local to
2044 read_the_mips_symtab rather than global.
2046 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
2048 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
2049 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
2051 * main.c (command_line_input): Flush stdout and stderr
2052 before every call to readline. This reportedly fixes a bug
2053 that comes up in Sys V running emacs-gdb and/or xxgdb,
2054 when stdin/out are pipes or sockets.
2056 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2058 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
2059 Avoid declaring Makefile dependencies, because GNU Make stupidly
2060 tries to update it if we do.
2062 * coffread.c: Revise for minor changes to bfd internal coff
2065 * configure: If -template= is given a relative path, make it
2066 absolute before recurring in subdirectories.
2068 * configure, configure.in, Makefile.in: Install "configure" script
2069 as replacement for config.gdb.
2070 * config.gdb, Makefile.dist, Makefile.sdir: Remove
2071 * README: Update for configure, mostly. FIXME.
2073 * Add dec3100 as equivalent to littlemips. Indicate in all host &
2074 target config files that they are for the host. When the lines
2075 get copied into the Makefile, this makes it more obvious what's
2078 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2080 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
2081 tabs, which end up in the disassembler output inadvertently.
2083 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
2085 Make it compile cleanly in an ANSI GCC2 environment.
2087 * blockframe.c: <stdio.h>
2088 * cplus-dem.c: free takes a void *, ifdef __STDC__
2089 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
2091 * defs.h (alloca): Avoid doing anything if alloca already def'd.
2092 * stddef.h, stdlib.h: Remove these files.
2093 * symtab.c: Avoid declaring qsort, close.
2094 * symfile.c: Avoid declaring close.
2095 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
2096 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
2098 Assorted other changes.
2099 * dbxread.c: include "libaout.h", not "liba.out.h".
2100 * printcmd.c (print_frame_args): Set recurse properly for
2101 indentation of struct and array parameters.
2102 * valops.c (value_cast): Allow cast to void.
2103 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
2104 single_step() in a target-independent fashion.
2105 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
2106 set up to be ready to continue. This makes us target independent.
2107 * infptrace.c (child_resume): Remove call to single_step; now
2108 can single step a SPARC target of any kind.
2110 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2112 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
2113 docn into separate sections---basically chapters, plus two loose
2114 pieces that can be configured to go in different places. This
2115 allows GNU m4 to preprocess the manual without coredumping.
2117 * Makefile.dist: tell TeX where to find texinfo.
2119 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2121 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
2122 the new target "rdl-apps.texinfo" which captures the Makefile
2123 variable that records where to find the Readline libraries.
2125 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
2127 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
2128 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
2129 * defs.h (const, volatile): Only define if not already defined.
2130 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
2132 * README: Update for release 3.95.
2133 * config.gdb: Don't create readline dir in subdir builds.
2134 * main.c: Include with "..." form for non-system include files,
2135 so "gcc -MM" for "make depend" works.
2136 Include readline files with "...h" rather than <readline/...h>.
2137 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
2139 * coffread.c: Undo minor damage done by Rich Pixley. Use
2140 different internal and external representations of COFF
2141 data structures. Use new BFD routines for swapping them in and
2143 * symfile.c (free_named_symtabs): Avoid freeing file names that
2144 are null or empty. Old i960 tools seem to produce files that
2145 claim to have empty names, causing each successive file read
2146 to blow away the previous one.
2147 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
2148 Move deferred_stores to top of file, but don't separate its
2149 #define's from its variable. Add commentary.
2150 * Makefile.dist: Fix Rich damage; undo "configure" changes in
2151 favor of keeping the (working) config.gdb. Move readline
2154 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
2156 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
2158 * infptrace.c (fetch_registers): no result, since now void.
2159 * tconfig/news: target depends on m68k-tdep too.
2161 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2163 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
2166 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
2167 applied various small fixes due to or inspired by RMS comments
2169 * doc/gdb.texinfo: finished using all RMS comments, save those for
2170 appendices on readline and cmd history (which are in other source
2173 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2175 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
2176 chapter 9; (2) documented 'break' command's menu mode for
2177 overloaded names, in response to hgs problem report C++ p-31
2179 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2181 * doc/gdb.texinfo: (1) better introductory example; (2) more
2182 consistent use of @code, @samp, @file, @kbd throughout; small
2183 cleanups to first three nodes; (3) new "Contributors" node;
2184 (4) Appendix, Renamed Commands; (5) divert specialized startup
2185 instructions to "Targets" chapter for generic manuals, while
2186 leaving them up front for manuals specific to specialized
2187 environments; (6) apply fixes from RMS comments through chapter 4.
2189 * pretex.m4: modify explanatory text slightly (and redefine
2190 "regexp") to keep GNU m4 from complaining. (It still crashes
2191 later, but one step at a time...)
2193 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
2195 * readline/readline.c (update_line): Avoid dereferencing a pointer
2196 before comparing it to its bounds. Saber caught this.
2197 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
2198 and only set PC if tgetstr returned non-null. Saber caught this.
2200 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2202 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
2203 stuff for config manual) here where it counts; updated
2204 to use new subdir structure (gdb/doc/).
2206 * Makefile: generated from above via
2210 * gdbint.texinfo: added instructions on generating gdb.info* files
2211 locally for release. These are ordinary info
2212 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
2213 Makefile)---but due to use of texinfo 2, can't count on makeinfo
2214 to generate these, so we distribute them already formatted.
2216 * gdb.texinfo: included full Info node and menu crud (as generated
2217 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
2219 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
2220 put in comments-for-future gdb.info target (one day makeinfo will
2223 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2225 * gdb.texinfo: Updated to include new or old undocumented
2226 commands, at least the following (perhaps some others I forgot to
2227 record): info f, info float, info path, info program, info s, info
2228 set, info source, info terminal, info types, info user, set/show
2230 Also covered all recent GDB command renames for v4.
2232 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2234 * mipsread.c: Rather than keeping count of how many symtabs
2235 and psymtabs we have, for sorting purposes, count them when
2236 we need to sort. This fixes bug in rereading of symbol tables.
2238 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2240 * infcmd.c: renamed "info path" to "show paths"

2254 * coffread.c, exec.c, infptrace.c, inftarg.c, remote.c, solib.c,
2255 symtab.h, target.c, target.h: Lint.
2256 * core.c: setup and select frame after reading shared libs,
2257 else reading shared libs will clobber them. Lint.
2258 * utils.c (error): Force out any buffered wrap text.
2260 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2262 * remote.c: Remove decls of memory_insert_breakpoint
2263 and memory_remove_breakpoint, no longer used. (Suggestion of
2266 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
2267 to make it easier to interface to "configure"'d libraries.
2269 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
2271 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
2272 aliases for set/show print.

2328 * coffread.c [TDESC]: Move setting of debug_info from
2329 coff_symfile_read to find_linenos and make it work with BFD.
2331 * cplus-dem.c [__STDC__]: Make x{m,re}alloc return void*.
2333 * signame.c: Cast const char* to char* when assigning to sys_siglist.
2335 * utils.c (strsave): Make arg const char* not char*.
2337 * infrun.c (wait_for_inferior) [SHIFT_INSN_REGS]: Use

2358 Mips bringup and general cleanup
2360 * cplus-dem.c: Move CPLUS_MARKER define to after defs.h.
2361 * infptrace.c (PT_WRITE_D, PT_READ_D): Use correct values.
2362 (This still doesn't seem to make MIPS bkpts work.)

2364 (symbol_file_command, add_file_command): Remove, obsol.
2365 * printcmd.c (ptype_command): Say "an enum" rather than "a enum".
2366 Wrap output appropriately.

2368 selected_frame rather than target_has_stack or coredumping.
2369 * valprint.c (type_print_varspec_suffix): Wrap "ptype" output of
2370 enums appropriately.
2372 Wed May 1 14:10:22 1991 Jim Kingdon (kingdon at cygint.cygnus.com)

2381 can have both ints and enum type_pieces in it.
2382 ({push,pop}_type_int): New functions.
2384 Tue Apr 30 13:18:58 1991 Jim Kingdon (kingdon at cygint.cygnus.com)

2397 copying.awk, solib.c, inflow.c, symmisc.c
2398 : Lint. Use read_memory not read_memory_integer on CORE_ADDR's.
2399 Use {value_as,unpack}_pointer (added to values.c)
2400 not {value_as,unpack}_long on CORE_ADDR's.
2401 Use longest_to_int (added to defs.h) instead of cast to int.
2402 Remove from_tty arg to mod_path.
2403 Put symfile_bfd in {coff,dbx}read.c not symfile.h.
2404 Use OP_NULL instead of 0 where dummy enum exp_opcode needed.

2900 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
2901 * core.c (core_detach): Unpush core_ops, which might not be on
2902 top. We used to just pop the top, which broke things. Don't
2903 need dont_repeat() any more.
2904 (core_file_command): Psst! Don't repeat it.
2905 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
2906 * expprint.c (print_subexp): Avoid switch fallthru on
2907 BINOP_ASSIGN_MODIFY, so we can print += and such.
2908 * frame.h: Fix typo.
2909 * inflow.c (kill_command): After killing inferior, print our
2910 current frame in the core file, if we have one.
2911 (generic_mourn_inferior): When inferior dies, either select
2912 the current frame (in the new target, e.g. core file), or
2913 set both the current and selected frames to NULL.
2915 Changes from Peter Schauer.
2917 * infptrace.c: Avoid <sys/ptrace.h> on USG.
2919 * Make all file names fit in 14 characters (sigh and damn!):

2930 * Makefile.dist, README, config.gdb, convex-pinsn.c,
2931 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
2932 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
2935 * command.c (user_info_1, user_info): New command for listing
2936 the user-defined commands.
2938 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
2940 * dbxread.c (really_free_pendings): Clear file_symbols
2941 and global_symbols after freeing them; otherwise, running
2942 this function twice (if it appears twice on the cleanup
2943 chain), we try to free things twice.
2945 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
2946 based on text_addr (the address of text in core), not on addr (the
2947 offset between text in the .o file and in core). This change
2948 is from Peter Schauer.
2950 * main.c: Define ALL_CLEANUPS as a cast of zero.
2951 (return_to_top_level): Use it.
2952 (main): Do all cleanups after each command run as part
2953 of the gdb startup sequence. Also do all cleanups before
2954 entering the command loop, and every time we exit the command
2955 loop and reenter. Before, the cleanups from the startup sequence
2956 were being left undone until the first error!
2957 (command_loop): Rename do_nothing cleanup to command_loop_marker
2958 so we can see it easily when examining the cleanup chain.
2959 (init_signals): Add another do_nothing for signal handling.
2960 (quit_command): Only try to kill target if it has execution.
2961 Problems in the target stack got us into a state where
2962 inferior_pid was nonzero but none of the targets had execution.
2963 In this state you couldn't exit gdb.
2965 * dbxread.c: Two changes from Peter Schauer.
2966 (echo_command): Fflush output after an echo command.
2967 (show_history): Pass all args to cmd_show_list.
2969 * utils.c (init_malloc): Call mtrace to turn on tracing
2970 if the environment variable MALLOC_TRACE is set to a file name.
2971 * mtrace.c: Add source file which provides a log of every malloc,
2972 free, and realloc to a trace file.
2973 * mtrace.awk: Add source file which analyzes the trace file.
2974 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
2975 (VERSION): Roll to 3.94.3.
2977 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
2978 (check_duplicates): Don't bother with watchpoints.
2979 (set_raw_breakpoint): Comment about danger of this routine.
2980 (watch_command): Parse and eval all args before calling
2983 * solib.c (find_solib): Avoid error in referencing memory to
2984 see if any more shared libraries have been added. This is
2985 particularly useful if the target has terminated. Bug reported
2988 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
2989 in bringing up 3.94.2 on the Sun-3.
2991 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
2992 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
2993 expression (in scope) before reenabling watchpoint.
2994 * signame.c (init_sigs): Add missing declaration of i, fix
2995 sys_siglist declaration.
2996 * source.c (list_command): Fixed range computation to use
2998 * stack.c (backtrace_command): Do not allow command if target has
2999 no stack, print informative error message.
3000 * target.c (target_command): Do not write into command line
3001 because this fails if the target command is used in a user defined
3002 command. [This change was enhanced by gnu to support any-
3003 unique-prefix matching on target names.]
3004 * valops.c (value_struct_elt): Avoid infinite loop on an
3005 erroneous attempt to print the member of function (try p main.p).
3007 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3009 * expread.y (name_no_typename): Avoid reduce/reduce errors
3010 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
3011 Since the GDB parser really doesn't use name_no_typename in a
3012 name-only context, the parser can't tell the diff between
3013 names and numbers here. Avoid allowing a name_no_typename
3014 to be a NAME_OR_*INT to resolve the conflict.
3016 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3018 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
3020 * valprint.c (val_print_fields): bitfield printing didn't handle
3021 byte order. Indirect through a few more fns to cope.
3023 * values.c (modify_field): also cope with byte order.
3025 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
3027 Cleanup for release 3.94.2:
3029 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
3030 include files. Roll version to 3.94.2.
3032 * coffread.c (init_stringtab): Read length into unsigned char
3033 array before swapping; don't assume 32-bit longs.
3035 * target.c (target_info): Don't bother with get_sym_file, just use
3036 the symfile global variable.
3037 * symtab.h, symfile.c (get_sym_file): Delete it.
3039 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
3040 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
3041 (read_type): Replace one more error() with complain().
3043 * mipsread.c (parse_partial_symbols): Replace printf with complain.
3045 * i960-tdep.c: Fix copyright attribution.
3047 * config.gdb: Quote all backquotes in doublequotes. You can
3048 quote me on that. BSD 4.4 shell found this one.
3050 * infptrace.c (throughout): The third argument to ptrace is an
3053 * infrun.c (wait_for_inferior): When program has terminated, we
3054 have to call target_terminal_ours before we pop that target off
3055 the stack (e.g. before a call to target_kill or
3056 target_mourn_inferior). This fixes problem where a program
3057 terminates, then GDB stops for (tty output) and you have to type
3058 "fg" to the shell to resume it. FIXME: This code for what to
3059 do after termination really should be in normal_stop instead.
3061 * gdbcore.h (read_memory_check): Change declaration; it changed
3064 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
3065 4.4 prereleases, this avoids a bug in their sgtty compatability
3067 * remote.c: Use terminal.h rather than hand-rolling the same.
3069 * signame.c, signame.h (psignal): Arg is unsigned, not int.
3070 * utils.c (strsave, strstr): Fix arg types.
3071 * valprint.c (val_print): lint
3073 MIPS symbol table support from Per Bothner:
3075 * symfile.c (symtab_fns): Remove initializer table that needs to
3076 be hacked for each new symbol file format supported.
3077 (add_symtab_fns): New function, chains symbol table
3078 handlers into the global list.
3079 (symfile_init): Search this list.
3080 * symfile.h: Add next pointer, declare add_symtab_fns.
3081 * coffread.c (_initialize_coffread): Call add_symtab_fns.
3082 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
3084 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
3085 symbol *). Thus, we no longer need the hack to trash
3086 pst->filename. Good, since that hack confused code in symfile.c!
3088 (reorder_symtabs, destroy_all_symtabs): Removed static
3089 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
3090 Instead, the latter now uses a temporary array (stack-allocated
3091 from an obstack, and then freed).
3093 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
3094 haven't been set in the outermost stBlock of a procedure. This was
3095 a problem with f77 binaries on Ultrix 4.?.
3097 (new_symtab, new_symbol, new_type): Continue changing code to use
3098 obstacks more and otherwise conform to dbxread internal style.
3099 Made the free_code of symtabs be free_linetable (as in dbxread)
3100 instead of free_contents. This implies memory leaks when reading
3101 a new symbol table, until the conversion is finished. Did change
3102 (struct symbol) and (struct type) to be allocated on the
3103 symbol_obstack. Blocks and blockvectors are among the things
3106 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
3107 tested much, but it solved one problem (reported by Meissner), and
3108 cleans up some other things. The problem happened when an
3109 included file contains actual code (functions) and not just
3110 definitions. The mips coff is a little inconvenient there, since
3111 it may cause a procedure to be mapped to the wrong psymtab.
3113 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
3114 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
3115 this will need work for the new core paradigm.
3117 Opcode patches from the net:
3119 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
3120 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
3121 missing altogether - they are added here. From Bruce Bauman.
3122 * mips-opcode.h: The low mask for C0 instructions was too small.
3123 From Garrett Lau. I modified the fix to check the entire 32-bit
3126 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
3129 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3131 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
3133 * dbxread.c (read_type): Pointer subtraction (value_sub in
3134 valarith.c) sometimes failed because the types of the
3135 pointers being subtracted were not identical.
3136 These differed because dbxread.c was allocating pointer types
3137 using dbx_alloc_type+smash_to_pointer_type instead of
3138 lookup_pointer_type. I failed to find a justification for the
3139 former, so I changed it to use the latter. Similarly, I
3140 replaced smash_to_function_type by lookup_function_type,
3141 and smash_to_reference_type by lookup_reference_type.
3143 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
3144 _initialize_mipsread): corresponding changes.
3146 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
3148 * source.c (mod_path): Do tilde_expand on each component of the path,
3149 rather than on the (list of) paths as a whole.
3150 (print_source_lines): Set first_line_listed in addition to
3151 current_source_symtab and current_source_line. If the source was
3152 not findable, after a "dir" command to fix the problem,
3153 a "list" would get the wrong lines.
3155 While I was there... (gnu):
3157 * dbxread.c (read_type): Change error to complaint.
3159 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3161 First attempt at detailed understanding of symbol table memory alloc.
3163 * dbxread.c (dbx_symfile_read): Free our string table if we
3164 aren't the mainline. Free the "info" struct since we're done with
3166 (init_psymbol_list): Free any previously allocated psymbol lists.
3167 (): FIXME: Should realloc-down the psymbol lists when done reading
3168 the main symbol file?
3170 * symmisc.c (free_symtab): Free fullname field too.
3172 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
3173 (REGISTER_ADDR): Make result type unsigned int.
3175 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
3176 define REGEX must also define REGEX1 (its dependency).
3178 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
3180 * tconfig/i960: No longer works, points you at vxworks960 or
3183 * xgdb.c, XGDB-README: Remove file. Users can get the much
3185 * Makefile.dist: Remove all trace of xgdb.
3187 * breakpoint.c (breakpoint_1): Pass demangle arg to
3188 print_address_symbolic.
3189 (clear_breakpoints): Remove unused function.
3190 (breakpoint_re_set_one): Guts of breakpoint_re_set.
3191 (breakpoint_re_set): Use catch_errors to do them all anyway.
3193 * gdb-int.texinfo (Host versus Target): Add section on what is
3194 a "host" feature versus what is a "target" feature.
3196 * infcmd.c (path_command, path_info): Handle the PATH variable
3197 (object search path) as conveniently as the source search path.
3198 * environ.c (set_in_environ): Set some vars in GDB's environment,
3199 in addition to the child's. PATH, G960BASE, G960BIN for starters.
3200 * source.c (mod_path): New function, from guts of
3201 directory_command, modifies a path. Used by path_command.
3202 (directory_command): Call it.
3203 * defs.h (strsave): Declare.
3205 * utils.c (sevenbit_strings): Add new printing option.
3206 (printchar): Use it.
3207 (strsave): Provide this handy helper routine.
3208 (set_width_command): Rename set_screen_width_command.
3209 (_initialize_utils): "set screen-width" => "set width";
3210 "set screen-height" => "set height"; add sevenbit-strings.
3212 * infcmd.c (do_registers_info): Print floating point registers
3213 in raw hex as well as float format, regardless of whether it is
3214 a "virtual" convertible register.
3215 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
3216 regs as a double, just in case it's being used that way.
3217 * values.c (unpack_long): Comment on array/function coercion.
3218 (unpack_double): Argument is in target byte order now. For
3219 integer arguments, just call unpack_long and float the result.
3220 * m68k-tdep.c: include defs.h for "const" handling.
3221 * remote-nindy.c: Use ieee-float stuff.
3222 (nindy_fetch_registers): Unpack double regs to host double, then
3224 (nindy_store_registers): Pack extendeds to host double, flip
3225 around by misusing unpack_double, send as target double.
3227 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
3228 zero, as when stopped at the first instruction of a process.
3230 * blockframe.c: Fix filename in comment (param.h => tm.h).
3231 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
3232 * tm-68k.h: Fix typos.
3234 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
3236 Changes from a bringup on the DEC Vax under Ultrix 4.0.
3238 * coredep.c (fetch_core_registers): Pass end-address of register
3239 section to register_addr as expected. Don't call supply_register
3240 if we'd just pass it garbage.
3242 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
3244 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
3246 * target.c (push_target, target_info): Cast enums to int for < or
3249 * stack.c (print_frame_info): Identify source file & line
3250 even if we can't print it.
3252 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
3254 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
3256 Clean up IEEE floating point support.
3258 * ieee-float.h: New file.
3259 * ieee-float.c: Write real routines to convert between host
3260 doubles and various target IEEE extendeds.
3261 * m68k-xdep.c: Eliminate assembler code for extended floats.
3262 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
3263 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
3264 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
3265 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
3266 double_to_ieee_extended.
3267 * i960-tdep.c: Define ext_format_i960.
3268 * m68k-tdep.c: Define ext_format_68881.
3269 * sparc-tdep.c: Define ext_format_sparc, though unused.
3270 * Makefile.dist (HFILES): Add ieee-float.h.
3271 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
3274 Obsolete the "coffstrip" program in favor of using BFD's strip.
3276 * nindy-share/coffstrip.c: Remove file.
3277 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
3278 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
3279 * tconfig/nindy960: Remove reference to coffstrip.o.
3281 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
3283 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3285 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
3286 * dbxread.c: Remove static symfile_bfd.
3287 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
3289 * inftarg.c (child_detach): Pop the child_ops vector if the
3290 detach is successful.
3291 * remote-nindy.c (nindy_create_inferior): Don't push a new
3292 nindy_ops since nindy uses the same one for execution and memory
3294 * core.c (core_ops): Use child_attach and child_create_inferior
3295 rather than default attach and create_inferior functions.
3297 Handle floating point registers in core files.
3299 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
3300 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
3301 This version untested since BFD doesn't yet support sun3 core
3303 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
3304 conventions. Fix comments and style. This version has not
3305 been compiled yet, since we have no HP inhouse.
3306 * core.c (get_core_registers): Look for two sections, ".reg"
3307 and ".reg2", and pass both to fetch_core_registers sequentially.
3309 Revise directory path yet again.
3311 * source.c (forget_cached_source_info): Not static any more.
3312 (init_source_path): New default source path is "$cdir:$cwd".
3313 (dir_command): Handle variable arguments ($cdir, $cwd).
3314 (source_info): Print "Compilation directory" rather than
3315 "Originally compiled in" to remind people of $cdir.
3316 (openp): If the path contains $cwd, use current directory.
3317 (open_source_file): If compilation directory is known, replace
3318 first $cdir in path with the compilation directory.
3319 (print_source_lines): Even if we can't print the lines, set the
3320 current symtab and line for future commands like "info source" or
3321 "breakpoint". Also, error message now contains the file name,
3322 line number, and file access error message.
3323 (_initialize_source): Fix help text to describe changes.
3324 * main.c (cd_command): Forget cached source info when we chdir.
3325 * utils.c (strstr): Add simple implementation.
3327 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
3329 * coffread.c (read_one_sym, init_linetable, init_stringtab):
3330 Byte-swap COFF symbol tables if necessary when reading them in.
3331 Use complain() to replace error message in one spot. Needs
3332 corresponding change in bfd/coff-code.h to make some symbol
3333 swapping routines non-static.
3335 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3337 Merge changes from Eirik Fuller, for UTek.
3339 * defs.h (errno): Add declaration.
3340 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
3341 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
3342 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
3343 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
3344 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
3345 declarations of errno.
3347 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
3349 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
3350 <rpc/rpc.h> and <rpc/types.h>.
3352 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
3354 * i960-tdep.c (examine_prologue): Add new argument limit,
3355 which stops the scan at the end of the prologue, or at the PC.
3356 This fixes a problem where it walks down into the code for the
3357 user's statements if that code looks like function prologues.
3358 Mark Fox and I have been bouncing this code back and forth, making
3359 small changes to it. Callers changed to match.
3361 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
3363 Cleanup for gdb-3.94 release final:
3365 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
3366 the .c files from vx-share and nindy-share, from the various
3367 macros, since they are not found via ALLDEPFILES.
3368 (SFILES): Add tm-i960.h.
3369 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
3370 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
3372 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
3373 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
3375 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
3377 * am29k-tdep.c: Add contribution line.
3378 (examine_prologue): Cache information about function prologues in
3379 the misc-function-vector to avoid lots of references over the
3380 serial line while examining instructions.
3382 * core.c (core_close): New function made from cleanup_core.
3384 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
3385 remote-vx.c, remote.c, target.c, target.h,
3386 Update target_ops vector to add attach, close, and load entries.
3387 Use add_syms_addr_command, not add_file_addr_command, for
3388 add_file. Break out close routine from existing code.
3390 * dbxread.c (really_free_pendings): Don't free pending_blocks;
3391 they are in an obstack.
3392 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
3394 (define_symbol): Add symbol type parameter; change callers;
3395 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
3396 it to influence the symbol class on the i960.
3397 (define_symbol): Swap LOC_CONST's into target byte order.
3399 * exec.c (exec_close): New function.
3400 (exec_file_command): Call it.
3402 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
3403 Fix byte order of frame pointer.
3404 (read_var_value): Result of 0 if var's value can't be found,
3405 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
3406 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
3407 (locate_var_value): Use read_var_value and use its lazy address
3408 as the location of the var's value. Lint.
3410 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
3413 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
3414 obsolete Intel versions in favor of vxgdb versions.
3415 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
3416 code dealing with byte order of values, which Intel did in host byte
3417 order rather than gdb-4's target byte order.
3418 (i960_frame_chain_valid): Move to nindy-tdep.c.
3419 (examine_prologue, skip_prologue, frame_find_saved_regs,
3420 frame_args_address, leafproc_return, saved_pc_after_call,
3421 pop_frame): Add vxgdb versions from Mark Fox.
3422 (examine_prologue, frame_struct_result_address): Add code
3423 to deal with the saved value of G13 (struct return address
3425 (frame_args_address): Modify Mark's version to prefer the
3426 saved value over the current value in the topmost frame.
3427 Cache result in the frame info to avoid performance hair in
3429 (print_fault): Add gdb960 code for printing faults.
3430 (_initialize_i960): Actually call check_host.
3432 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
3433 add stub routines. FIXME, these currently just return zero!
3435 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
3436 (attach_command): Call target_attach, not target_open, now.
3438 * infrun.c (normal_stop): Make global, not static, for vx_attach.
3439 (child_attach): Rename from child_open.
3440 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
3441 don't confuse it with a zero step_resume_break_address.
3443 * inftarg.c (child_detach): Eliminate inferior_pid test.
3444 (child_files_info): Clean up message a bit.
3445 (child_ops): Use child_attach, not child_open, to attach.
3447 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
3448 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
3449 findvar.c to here, since it depends on the contents of the
3450 shadow_contents of breakpoints, but keep if #if 0 since it is
3453 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
3456 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
3457 (ptype_command, display_command): Eliminate have_inferior_p and
3458 have_core_file_p in favor of target_has_stack or
3459 target_has_execution.
3460 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
3461 code for actually finding the values of arguments, though we still
3462 keep track of the maximum stack offset for use in printing unnamed
3463 arguments. Handle missing FRAME_ARGS_ADDRESS.
3465 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
3466 (struct nindy_regs): Define registers passed to/from nindy.
3467 (nindy_fetch_registers, nindy_store-registers): Translate between
3468 nindy and GDB formats for the registers.
3469 (dcache_init): Statically allocate the cache, since it was being
3470 allocated by a malloc that was never freed anyway.
3471 (nindy_create_inferior): Error, not core dump, if no exec file.
3472 (nindy_before_main_loop): Use target_load, not target_add_file.
3474 * remote-vx.c (net_load): Specify large timeout for load
3475 requests. Allow user to break out with INTERRUPT.
3476 (net_break): Remove useless code, clean up. Change callers.
3477 (parse-args, skip_white_space, find_white_space): Clean up arg
3478 parsing to cope with quoted strings.
3479 (net_wait, net_quit): Never call error, just return status.
3480 (vx_read_register, vx_write_register): Cleanup status checking.
3481 #ifdef the code based on which CPU we are using (960 or 68k),
3482 FIXME, this should be completely general but it isn't yet.
3483 (vx_xfer_memory, vx_resume): Cleanup status checking.
3484 (vx_run_files_info): Improve message.
3485 (vx_load_command): Renamed from vx_add_file_command. Allow load
3487 (net_ptrace): Remove unused routine.
3488 (vx_wait): Adopt code from vxgdb960 to cope with broken
3489 connections to target machine and prompt to disconnect. Remove
3490 debug printouts. Map some EVENT_'s to SIGnals.
3491 (add_symbol_stub, vx_open): Print names of object files we found,
3492 and "ok" if we read their symbols OK. Clarify output in general.
3493 (vx_attach, vx_detach, vx_kill): Add these commands.
3494 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
3495 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
3496 "info files" output, and create_inferior, since we already have
3499 * stack.c (frame_info): Replace Frame_unknown with 0.
3500 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
3501 (return_command): Pop until the PC matches as well as the FP,
3502 so it works even if the FP is shared with another function,
3503 as in "frameless" or "leaf" procedures.
3505 * symfile.c (load_command): renamed from add_file_target_command.
3506 (add_syms_addr_command): renamed from add_file_addr_command.
3507 (add_syms_command): Stub to call target_add_syms.
3508 (_initialize_symfile): Change command names and descriptions,
3509 add-file => add-syms, and load from alias to its own command.
3511 * target.c (kill_or_be_killed, maybe_kill_then_attach,
3512 maybe_kill_then_create_inferior): Default for attempts to start
3513 a process, if one is already running, is to ask about killing
3514 it and retry if yes.
3515 (upstack_create_inferior): #if-0 it, strata obsolete it.
3516 (push_target, unpush_target, pop_target): to_close() a target
3517 before unstacking it.
3518 (target_info): Renamed from target_files_info.
3519 (_initialize_targets): Rename "i files" as "i target", accessible
3522 * target.h: Improve comments about the target_ vectored routines.
3524 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
3525 Convert commenting style to standard GNU style.
3526 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
3527 (SKIP_PROLOGUE): No longer a no-op.
3528 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
3529 (*_REGNUM): Sort register numbers.
3530 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
3531 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
3532 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
3533 are now 10 byte extendeds, not 8 byte doubles.
3534 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
3535 for nindy versus vxworks targets. FIXME, this should possibly go
3536 in the target vector.
3537 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
3538 frame_saved_regs and arg pointer with each frame.
3539 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
3540 (FRAME_ARGS_ADDRESS): Use cached result.
3541 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
3542 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
3543 (PRINT_RAMDON_SIGNAL): Call print_fault.
3544 (POP_FRAME): Now works.
3546 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
3547 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
3548 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
3549 (ADDITIONAL_OPTION_HANDLER): use target_load, not
3552 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
3553 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
3555 * valarith.c (value_subscripted_rvalue): Avoid handling
3556 floats and doubles specially; it gave alignment errors. Lint.
3558 * valops.c (value_of_variable, value_of_this): Error if unknown
3561 * valprint.c (print_floating): Bcopy rather than pointer-deref,
3562 to avoid alignment problems.
3563 (value_print): Handle unknown value address.
3564 (cplus_val_print): Two args are ignored; remove them. Change caller.
3565 (val_print): Use unpack_long rather than pointer-deref.
3568 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
3569 to avoid alignment problems.
3570 (value_being_returned): Error if return value unknown.
3571 (set_return_value): Add bogosity warning, FIXME. *
3573 * TODO: A woman's work is never done.
3575 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
3576 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
3577 Add ieee-float.o to OBS.
3578 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
3579 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
3580 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
3582 Changes to generalize the VxWorks RPC protocol slightly, to handle
3583 i960 as well as 68000.
3585 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
3586 * vx-share/reg.h: Produce i960 regs #ifdef I80960
3587 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
3588 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
3589 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
3590 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
3591 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
3592 so they will move in target byte order rather than network
3593 byte order (happens to be the same).
3595 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
3597 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
3599 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
3602 Add contribution lines to various files, showing where they
3605 * breakpoint.c (break_insn, check_break_insn_size,
3606 read_memory_nobpt): Remove to mem-break.c.
3608 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
3611 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
3612 entry has bad register number. This change is not
3613 tested in this release, FIXME.
3615 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
3618 * value.h: Force value's contents field to be aligned to hold
3619 at least a double or a long long (if supported). This avoids
3620 doing bcopy's in and out of the contents field.
3622 (step_1): Avoid coredump under obscure circumstances when we
3625 * symtab.h (misc_info): Add field to misc function vector for
3626 any kind of cached information the target code desires. AMD
3627 29000 uses this to avoid repeating examine_function_prologue's.
3629 * coffread.c: Lint. Remove static symfile, read_section_header.
3630 core.c (have_core_file_p): Lint: remove.
3631 expprint.c (print_subexp): Lint.
3632 infptrace.c, valops.c, valprint.c: lint.
3634 Roll in changes from vxgdb-5.0.1:
3636 * symtab.h: Comment byte order of each address class. Add
3637 LOC_LOCAL_ARG for frame-relative args (960).
3638 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
3639 symtab.c, symmisc.c: ditto.
3641 * infrun.c (init_wait_for_inferior): Clear stop_signal.
3643 * remote.c (remote_resume): Error if resume with a signal.
3645 * symfile.c (prim_record_misc_function): Clear misc_info.
3646 (fill_in_vptr_fieldno): Check stub type of arg.
3648 * valops.c (value_cast): Avoid looking up names of types whose
3649 name we don't know, to prevent coredump. Sun CC produces typedef
3650 rtx and the name of *rtx is zero...
3652 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3654 Roll in changes from final AMD 29000 port (Tiemann).
3656 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
3657 for ../include/a.out.encap.h. This might not work now that BFD
3658 is separately compiled. Instead, BFD support for encap will have
3659 to translate machine type 29k into the right COFF_MAGIC.
3661 * infcmd.c: Remove references to inferior_pid that aren't used
3662 in actual ptrace calls; use target_has_execution, etc.
3663 (have_inferior_p): Remove function.
3664 (program_info): Print target info rather than "process number";
3665 avoid gratuitous messages unless from_tty.
3666 (run_stack_dummy, finish_command): Set proceed_to_finish.
3667 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
3668 main.c: Lint. Lose have_inferior_p().
3669 inferior.h (have_inferior_p): Remove, lint.
3670 (proceed_to_finish): Add flag to ask that all regs be saved
3671 by normal_stop, for the few commands that need it, speeding up
3672 serial I/O. Add comments to stop_registers.
3674 * remote-eb.c: Remove newline from breakpoint message we grep
3675 for. Never time out when running the user program.
3679 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3681 Roll in changes from vxgdb-5.0.1:
3683 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
3684 symbol in its raw form, we are processing an unlinked ".o" file.
3685 See if the target environment has assigned it an address, using
3686 target_lookup_symbol (VxWorks does), and enter it into the symtab
3689 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
3690 68k versions for a simpler version that assumes zero FP at bottom.
3691 Fixes bug of truncated stack reports.
3693 * target.h (target_lookup_symbol): Define this routine's args
3694 and result, finally.
3696 * target.c (nosymbol): Default routine for target_lookup_symbol.
3697 (target_default): Default lookup_symbol and call_function too.
3698 (files_info): Only print has_all_memory warning if a non-dummy
3701 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
3702 vx_convert_from_virtual): If target does not have floating point,
3703 zero register "values", and avoid doing cross-net conversions.
3704 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
3705 (vx_open): Rearrange code that attaches to target and reads
3706 symbols for all loaded modules, to work if some of the modules
3707 are not accessible. Add symbol_stub() and add_symbol_stub()
3708 as callbacks from catch_errors(). Allow connect attempt to be
3709 interrupted painlessly with ^C (FIXME, there are still some bugs
3710 if the interrupt happens during symbol reading.). Print
3711 final message with puts_filtered, since symbol messages are
3716 * main.c (catch_errors): Only print errstring if non-null.
3717 (command_loop): Avoid an ioctl per command to test ISATTY.
3719 * remote-vx.c (net_load): make static; avoid sophomoric msg.
3720 (vx_xfer_memory): Return correct result!
3721 (vx_files_info): Indicate whether target has float or not.
3722 (vx_lookup_symbol): Complain, not error, if target gone.
3723 (vx_open): Print "Connected" msg before disabling immediate-quit.
3724 [FIXME: lookup_symbol and vx_open changes need testing.]
3726 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
3727 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
3728 contributor lines and update copyrights to 1991.
3730 Changes from an attempted H-PUX host port:
3732 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
3733 defines PT_ATTACH and PT_DETACH but not PT_KILL.
3734 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
3735 * remote-vx.c: include <sys/time.h> for HPUX.
3736 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
3737 "core_file_command" routine to BFD regime. May not work yet.
3739 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
3741 * xgdb.c: Replace X10 version with some VJ version.
3742 (FIXME: Its copyright assignment is not on record.)
3743 * xgdb.c: Update include files to X11R4 (Xaw crud).
3744 (xgdb_display_source, create_text_widget): fix call to
3745 get_filename_and_charpos. Rewack source window stuff for X11R4
3746 (gleaned from include files, and "nm's" of binary libraries, since
3747 I had no doc available).
3748 (append_selection, append_selection_word): Disable with FIXME
3749 since R4 changed interface here.
3750 (create_buttons): Add back the old set of buttons.
3751 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
3753 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
3754 Roll VERSION to 3.94 (not yet final though).
3756 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3758 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
3759 obstack_int_grow, obstack_int_grow_fast): Eliminate
3760 cast on left of assignment, which gives MIPS cc fits and is
3763 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
3764 F_ALIAS. Use printf, not fprintf, when not passing a file
3766 (compare_opcodes): Check that identical instructions have
3767 identical opcodes, complain otherwise.
3769 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
3770 was reported by Roland McGrath.
3771 (unimp): Only match if exactly zero instruction. (Roland)
3772 (branches and traps): Generate all variations of these
3773 instructions with macros, based on a single call that defines
3774 each condition name and its binary representation.
3775 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
3777 * valprint.c (val_print_fields): Take, and use, format parameter.
3778 This means that "p/x struct" again prints the elements in the
3779 desired format. Changed callers.
3781 * stack.c (frame_info): Use filtered output, and indicate wrap
3782 points. Remove kludgy formatting designed to avoid line wrap.
3784 * utils.c (wrap_here): If the line is already full (because
3785 we had printed a long indent or long wrapped string), do an
3786 immediate newline-and-indent.
3788 * m68k-pinsn.c (print_insn_arg): Bugfix from
3789 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
3790 instruction is incorrectly disassembled as bkpt #8.
3792 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
3793 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
3794 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
3795 and then will dump core (sometimes). I traced it back to an
3796 uninitialized symfile_name in psymtab_to_symtab.
3797 (const_vol_complaint): Add quotes to message.
3798 (define_symbol): Only believe line number if gcc_compiled.
3799 Avoid allocating symbol if we will not return it.
3801 Add target strata support so that newly established targets go
3802 into their right place in the target stack (e.g. a new exec file
3803 doesn't wipe out the ability to access the running process).
3805 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
3806 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
3807 and initialize it properly in all the targets.
3809 * target.h: Document strata. Change return type of push_target.
3811 * target.c (nomemory): new function for dummy memory access.
3812 (tcomplain): Rename complain, now also used in symfile.c.
3813 (push_target): Push targets within strata. New return value shows
3814 whether new target is on top of stack or not. Always keep dummy
3816 (target_files_info): Ignore dummy target.
3818 * core.c (core_open): Warn user, and skip accessing file, if the
3819 core target is not the topmost target in the stack.
3820 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
3823 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
3824 target_ops, it doesn't belong there since we have no regs there.
3825 Change name of target from machine => memory to clarify.
3827 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
3829 * Freeze version 3.93 for release.
3831 * Makefile.dist: Handle vx-share and nindy-share subdirs
3832 properly when building gdb.tar.Z.
3834 * symtab.c: lint; add no_symtab_msg to consolidate the messages
3835 printed in various places, so I could change just one copy.
3837 * dbxread.c, coffread.c: Change references to bfd->iostream
3838 to cast to FILE *, now that BFD avoids needing types defined
3839 in other header files.
3841 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3843 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
3844 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
3845 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
3846 (actually gcc -Wall).
3848 * dbxread.c: Remove first_global_sym, last_global_sym, since
3849 they are never referenced.
3851 * defs.h (baud_rate): Declare.
3852 main.c: Define it, and add the -b option to set it.
3854 * gdb-int.texinfo: Add text on how to define a new host or target
3855 architecture, prompted by Per Bothner's questions about MIPS
3858 * gdb.texinfo: Document "complaints". Change doc of -q since
3859 gdb no longer prints the copyright and blurb if you specify a file
3860 name to be debugged (just like Emacs). Add doc for Nindy-specific
3861 command line flags for specifying target serial port and such.
3862 Update copyright to 1991.
3864 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
3865 has taken over for us the job of ripping up executable files. The
3866 crud caused Per Bothner's port to not compile.
3868 * infrun.c (normal_stop): Avoid printing "Program exited
3869 normally" if we are in batch mode. This allows a GDB which
3870 executes a program on a target system, to behave like a Unix
3871 command (input from stdin, output to stdout, no extraneous
3874 * main.c (main): Allow additional machine-dependent command line
3875 options to be specified with the ADDITIONAL_OPTIONS,
3876 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
3877 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
3878 processing to occur just before the main loop with
3879 BEFORE_MAIN_LOOP_HOOK.
3880 (main): If a "core file" argument is specified, and it is not a
3881 core file, try it as a process ID to attach.
3882 (symbol_completion_function): Attempt to cope with
3883 "show screen-" TAB, not very successfully. This needs more work,
3885 (batch_file): New function, returns whether we are reading
3886 commands from an interactive tty on stdin, or from somewhere else.
3887 Called by normal_stop since it doesn't get from_tty passed down
3888 to it like many commands do.
3890 * remote-nindy.c: Handle command line options for nindy
3892 (nindy_before_main_loop): Prompt user for tty name if they
3893 don't specify it before getting to the interactive command loop.
3895 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
3896 and -r command line options. Also add hook before main loop
3897 to make it easy to specify a tty.
3899 * TODO: More things to do, one done.
3901 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
3903 * dbxread.c: Make complaint() calls pass pointer, not struct.
3904 Add complaints about badly formatted C++ type information
3905 (const/volatile indicator, and parse errors resulting in
3906 error_type). Fix C++ virtual member fn comment.
3907 (read_struct_type): Avoid bumping pointer if we got a parse
3908 error; this prevents our walking beyond the end of a string.
3909 Terminate loop on null char as well as semicolon.
3910 (process_one_symbol): Fix the LBRAC fix so that it uses the
3911 last previous SLINE, FUN, or SO record's PC address. C++ debug
3912 symbols did not have SLINE records in a useful order compared
3913 to the LBRAC records.
3914 (define_symbol): Handle "catch" records.
3916 * symtab.c (check_stub_type): Added new complain
3917 `stub_noname_complain' and added a consistency check to
3918 keep the debugger from crashing when finishing from an
3919 exception frame. A real fix will be needed later.
3921 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
3923 * infcmd.c (attach_command): Make global.
3925 * Makefile.dist (REMOTE_OBS): Make these compile by default,
3926 but make them easy to comment out. Perhaps later they should
3927 be enabled by what CPU you configure for? FIXME.
3928 (VERSION): Roll to 3.93.
3929 (pinsn.o): Remove rule for obsolete file.
3930 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
3932 Run down a problem that manifested by printing the wrong function
3933 name in stack traces of read_ofile_symtab. Turned out that the
3934 problem was the SunOS 4.1.1 (and previous) C compiler outputs
3935 the LBRAC symbol with an address in the *data* segment, which
3936 blew our binary search through the blocks.
3938 * dbxread.c: Use the complain() facility consistently to bitch
3939 about problems in the symbol file we are reading.
3940 (finish_block): Add code to check the nesting of the blocks;
3941 complain and Procrust them to fit if wrong.
3942 (make_blockvector): Check the order of the blocks, complain
3943 [but don't cope] if wrong.
3944 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
3945 symbols to be sure their PC value is greater than the last SLINE
3946 (line number) symbol we've seen, complaining and adopting the
3947 SLINE PC value if wrong.
3949 * symfile.h (struct complaint, complaint_root, complain,
3950 clear_complaints): Add.
3951 * symfile.c (complain, complaint_root, clear_complaints): Add
3952 facility to deal with non-fatal complaints and to regularize their
3954 (symbol_file_add): Clear complaint counters to allow new complaints.
3955 (initialize_symfile): Add 'set complaints' and 'show complaints'.
3957 * dbxread.c (dbx_symfile_read): Remember the address and size
3958 of the string table for the main symbol file, so we won't read it
3960 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
3961 to avoid reading the string table yet again. Lint.
3962 (throughout): Improve filtered output, including word wrap.
3963 (read_range_type): Improve Bothner's fix to handle other types too.
3965 * utils.c: Improve line wrap implementation. Handle unlimited
3966 width by making chars_per_line unsigned.
3967 (puts_filtered): New, easy, function.
3969 * defs.h (puts_filtered): add.
3971 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
3972 call the identical sort_symtab_syms() in symfile.c instead.
3974 * expread.y: Suggest the `file' command rather than `symbol-file'.
3976 * command.h (enum var_types): Add zinteger for seroable
3978 * command.c (do_setshow_command): Handle var_zinteger. Restructure
3979 nested if's into a switch.
3981 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
3982 we did not stop because of a breakpoint (it must have been for
3983 some other reason, like a "stepi"), so don't print anything.
3985 * symtab.c: Include <sys/types.h> all the time. Now that BFD
3986 doesn't include <sys/types.h>, old SunOS's require it for
3989 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
3991 A test port of gdb-3.92.6 to the Sony NEWS.
3994 Don't normally link in remote- or vx stuff.
3995 Some of it doesn't compile, and it wastes space for 99% of the users.
3996 Remove reference to no-longer-used HAVE_VPRINTF.
3997 Fixed BFD_DEP typo to BFD_DIR.
3999 Fix cast in arg to bfd_h_getlong.
4000 Make char *prefix be const.
4001 Fix how certain range types are mapped into builtin unsigned int types.
4003 Remove 2 #includes. They cause errors (on Sony, at least),
4004 and aren't needed (they wern't in earlier versions).
4006 print_address_symbolic should never demangle labels
4007 (since it prints *assembler-level* labels).
4009 [This was superseded by the change to printcmd below.]
4012 Add some "volatile" return types to avoid warnings.
4013 If MISSING_VPRINTF add vprintf function and not just macro
4014 (since vprintf is used in printcmd.c).
4016 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
4017 (The latter isn't grokked by some PCC-based compilers.)
4019 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
4021 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
4022 * nindy-share/coffstrip.c
4023 Added some forward declarations (otherwise, gcc complains
4024 about implicit extern redefined as static).
4026 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
4028 Changes inspired by Per Bothner:
4029 * printcmd.c (print_address_symbolic): Take additional parameter
4030 specifying whether to demangle.
4031 (print_address): Pass in asm_demangle to control demangling.
4032 (print_address_demangle): New fn, takes explicit arg to control
4034 * utils.c: Add new vars demangle and asm_demangle, and let them
4036 (fputs_demangled): If !demangle, just print the argument.
4037 (fprint_symbol): If !demangle, just print raw symbol.
4038 * valprint.c (val_print): Call print_address_demangle rather than
4039 print_address, to cause demangling to depend on the global
4040 rather than assembler-level demangling setting.
4041 * WHATS.NEW, gdb.texinfo: Document.
4043 * main.c (show_command): Show all settings if no arg.
4044 (initialize_main): Make "info set" the same as naked "show".
4045 * command.c (cmd_show_list): Handle prefix commands in the
4046 list, and print the name of the setting as well as its English
4047 description and value.
4049 Allow gdb functions to specify where a line should wrap if it
4050 exceeds the size of a terminal line. Use it to make the output
4052 * utils.c (set_screen_width_command): New fn, mallocs a buffer
4053 of the right size when screen width changes.
4054 (set_screensize_command, screensize_info): Remove #if 0'd fns.
4055 (wrap_here): New fn, indicates a point in the output where we
4056 should wrap the line rather than just letting it overflow at a
4058 (fputs_filtered): Implement wrapping.
4059 (n_spaces): New fn, returns a pointer to N spaces.
4060 (print_spaces_filtered): Use n_spaces.
4061 * defs.h (n_spaces): Declare.
4062 * stack.c (print_frame_info): Wrap with 4-space indent after
4063 fn name and before filename and line number.
4064 * printcmd.c (print_frame_args): Wrap with 4-space indent
4065 before each argument name is printed.
4066 * valprint.c (value_print): Wrap with no indentation before
4068 (val_print_fields): Wrap with indentation relative to nesting
4069 level before each field name.
4070 (val_print): Wrap with nesting indentation before array elements.
4071 * command.c (do_setshow_command): Avoid extra newlines,
4072 wrap with 4-space indent around values printed, end with period.
4073 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
4075 * breakpoint.c (breakpoint_1): Implement addressprint for
4076 "info breakpoints" display. Change file name and line number
4077 format to " at file:nnn" rather than " (file line nnn)".
4078 * gdb.texinfo: Document.
4081 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4083 Frozen for gdb-3.92.6 release.
4085 README, WHATS.NEW: Update for 3.92.6 release.
4087 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
4088 coffread.o from configs since it is now built by default.
4089 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
4090 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
4091 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
4092 from configs since it is now built by default.
4094 Makefile.dist: Update for release 3.92.6. Handle files that
4095 have been moved to ../include, ../getopt, or ../bfd. Add
4096 saber.suppress and tests directory. Add config.status to
4097 the release (it will say "none").
4099 coredep.c: Minor formatting fixes.
4101 These changes were made in early December but only checked in now:
4102 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
4103 nindy-share/nindy.c: lint
4104 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
4105 register values coming back from the target; we store values
4106 in target byte order everywhere.
4108 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
4110 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
4112 * valprint.c (cplus_val_print, val_print_fields): New functions,
4113 which print C++ objects. They conspire to avoid printing a
4114 virtual base class more than once, following all the twists and
4115 turns of C++ virtual base rules.
4116 (val_print): Call the above rather than do it by hand.
4118 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
4119 symbol file, not for added files like shared libs. This really
4120 needs to be generalized to a timestamp per file.
4122 * core.c (cleanup_core): Avoid coredump if no core file.
4124 * config.gdb: Accept -host or -target in place of +host or
4127 * coffread.c (find_linenos): Avoid desupported BFD interface
4128 to line numbers. We still read them manually rather than using
4129 BFD's "generic" features.
4131 * gdbrc.tex, threecol.tex: Add GDB reference card and its
4133 Makefile.dist: Add refcard to OTHERS list for creating tar files.
4135 * Makefile.dist: Eliminate use of $< in explicit targets.
4137 * readline/Makefile: Use $< rather than $*.c, which does not
4138 include the VPATH in GNU Make.
4140 * tconfig/i960-bout, tconfig/i960-coff: These are identical
4141 copies of tconfig/i960, added for global configuration
4142 compatability. All i960 versions can read both coff and b.out.
4144 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
4145 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
4148 * TODO: Think of more things to do.
4150 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
4152 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
4153 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
4154 64-bit float conversion.
4156 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
4157 equivalent to sun?os4 so global config works.
4159 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
4161 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
4163 * main.c: Only declare linesize once; declare pagesize not at
4164 all, since it is never used.
4165 (main): Clear newly allocated line before it is used.
4167 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
4169 Further stabilization for the Intel 960.
4171 * Makefile.dist: Parameterize the location of the "include"
4172 and "bfd" directories, as well as "getopt". Add symfile.c.
4173 Link in both dbxread and coffread. Fix up "make depend" to
4174 rewack the locations of include, bfd, and getopt in its output.
4176 * README: Document moving include files, improve some of
4179 * coffread.c: Move common code out to symfile.c. Change
4180 symbol_file_command style interface to use new *_symfile_init
4181 and *_symfile_read interface under BFD. Use BFD internal
4182 info to locate line table, symbols, etc.
4184 * core.c (core_fetch_registers): Rename to get_core_registers
4185 to avoid confusion with fetch_core_registers.
4186 (register_addr): Move to coredep.c, which is already machine
4187 dependent. This leaves core.c pretty clean of dependencies.
4189 * coredep.c (register_addr): Accept this routine from core.c.
4191 * dbxread.c: Move common code (with coffread.c, etc) into new
4192 symfile.c. Each psymtab now contains a pointer to the
4193 format-dependent function that knows how to read it in. Make
4195 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
4196 (process_one_symbol): Add code to complain about a "compiler bug
4197 we muzzle here", if we actually see it.
4199 * eval.c (evaluate_subexp): Insert missing "break" statements
4200 in code that determines whether a variable is an lvalue in
4201 memory, register, or whatever. I detected this via a compiler
4202 bug in which it *almost* mashed out the whole switch statement.
4204 * gdb-int.texinfo: Add minor sections on configuring gdb for
4205 release, and about the README file.
4207 * infcmd.c (registers_info): Fix formatting somewhat. Still
4208 not as pretty as before, but it handles byte swapping.
4210 * remote-nindy.c: If data cache routines are interrupted while
4211 waiting for the remote end, be sure that any uninitialized cache
4212 blocks are on the free list, not on the valid list!
4214 * symfile.h: Flesh out this header file with all the various
4215 routines and variables that have been merged in from dbxread.c
4216 coffread.c, and symtab.c to symfile.c.
4218 * symfile.c: New file, containing code common to dbxread.c,
4219 coffread.c, and some code from symtab.c. All generic code for
4220 reading symbol files should be in here now.
4221 (unrecord_misc_function): Remove unused function.
4223 * symtab.h: Remove file-reading things to symfile.h.
4225 * symtab.c: Remove file-reading things to symfile.c.
4227 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
4228 to decode i960 fault types.
4230 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
4231 target.c: Change type of the "resume" function from int to void,
4232 since its result was never used.
4234 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
4236 * main.c: Replace "stupid" with "caution"; you now "set caution
4239 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
4241 * infcmd.c (do_registers_info): Call val_print to deal with the
4242 byte order of the registers being printed. FIXME, this makes
4243 the formatting of the output uglier.
4245 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
4246 defined, call it for signals the debugger doesn't itself use.
4247 The i960 uses this for more detailed fault information.
4249 * remote.c (remote_open): If arg is null, print help rather than
4252 * sparc-xdep.c (register_valid): Avoid declaring size, since
4253 various modules will think of various sizes depending on the
4254 architecture of their tm-file. FIXME, we need protection against
4255 actually entering one of those modules, which would clobber
4256 storage if not for the target architecture compiled into gdb.
4258 * stack.c (up_command, down_command): Always print the frame
4260 (up_silently_command, down_silently_command): New commands
4263 * i960-pinsn.c (reg), i960-tdep.c: Lint.
4265 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
4266 more parameters than it used to.
4268 * findvar.c (registers): Increase slop to 256 bytes, which should
4269 protect us against even most RISC machines with large register
4271 (locate_var_value): Move declaration inside related ifdef.
4273 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
4274 throughout, to avoid throwing away buffered input from the board.
4275 (nindy_wait): Supply_register takes addr_of_value, not value.
4276 (i960_print_fault): Renamed from i80960_fault.
4277 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
4278 (nindy_store_registers): Avoid regs_changed stuff, just stuff
4280 (nindy_create_inferior): Don't bother to write PC_REGNUM since
4281 we can set the PC in the call to proceed(). Unpush nindy_ops
4282 before pushing it on top, to avoid message to user. Eliminate
4283 commentary from Unix machines that just misleads here.
4284 (reset_command): Fix error message to suggest target command.
4286 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
4288 Release 3.92.5 as frozen.
4290 Stabilize the merged release...with help from lint, Saber C,
4293 Everywhere: Add include files needed to declare return types
4294 of functions called.
4296 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
4298 * breakpoint.h: Add undeclared breakpoint functions, and some
4299 functions for display handling since I couldn't think of a better
4302 * breakpoint.c (insert_breakpoints): Make code for disabling
4303 shared library bkpts more likely to work. It's used when we
4304 rerun a program and stop before the shared library has been
4306 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
4307 cast from pointer, so it squeezes through catch_errors.
4308 (bpstat_stop_status): Fix logic broken some time ago. We now
4309 always create a bpstat if the stop address matches a breakpoint,
4310 even if we don't stop there -- just like the old code used to do
4311 before I got my fingers into it (sigh).
4312 (breakpoint_1): Print "ignore count" after "stop only if"
4313 condition, since that's how it actually works.
4314 (mention): Handle watchpoints as well as breakpoints.
4315 (watch_command): use set_raw_breakpoint and mention to do most
4316 of the work (and initialize all the fields!). Only pass one
4317 arg to parse_c_expression, since that's all it takes.
4319 * command.c (not_just_help_class_command): Rename arg to args
4320 since we ignore "unused argument" warnings on vars named "args".
4321 inflow.c (child_terminal_info): ditto.
4322 infptrace.c (kill_inferior): ditto
4323 main.c (catch_errors, version_info, quit_command, pwd_command,
4324 source_command, dump_me_command, editing_info,
4325 set_history_size_command, set_history, show_history,
4327 stack.c (locals_info): ditto
4328 target.c (target_files_info): ditto
4329 valprint.c (set_input_radix, set_output_radix): ditto
4331 * core.c: Remove old variables for handling core and exec file
4332 sections (data_start, data_end, stack_start, stack_end,
4333 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
4334 text_end, exec_data_start, exec_data_end, text_offset,
4335 exec_data_offset, data_offset, stack_offset). They're
4336 superseded the more general build_section_table and
4338 (get_exec_file): Mention the `file' command.
4339 (read_memory_check): Rename to memory_error, and only call it
4340 in the case of an actual error.
4341 (read_memory, write_memory): call memory_error.
4342 (core_fetch_registers): Register section name is ".reg".
4344 coredep.c: Remove a bunch of crud now that all this file does
4345 is pull the registers out of a core file.
4346 (fetch_core_registers): Rewrite to actually work, I hope.
4348 dbxread.c: Use a.out.gnu.h, not system a.out, now.
4349 Replace index() with strchr(). Remove all the pre-BFD macro
4350 definitions for accessing the symbol file.
4351 (struct dbx_symfile_info): Encapsulate the information that
4352 dbx_symfile_init needs to pass to dbx_symfile_read in this
4355 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
4356 dbx_symfile_discard): Rearrange symbol file reading to divide
4357 the format-specific part from the format-independent part,
4358 leaving the format-independent part such as file name expansion
4359 and opening in symtab.c. This replaces
4360 partial_symbol_file_open and partial_symbol_file_read.
4361 Symbol_file_read, add_file, add_file_target_command,
4362 add_file_addr_command move to symtab.c. Pass an explicit
4363 "mainline" flag for when reading the main symbol table, rather
4364 than relying on the offset address to be zero or nonzero.
4366 (dbx_symfile_read): Don't allow void *'s to be printed as
4368 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
4369 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
4370 macro" debug version really work.
4371 (read_dbx_symtab): Remove unref'd parameter inclink.
4372 Avoid swapping N_SLINE symbols, for speed.
4373 Merge N_TEXT!N_EXT case with the other external symbol
4374 definitions' case. Add comments.
4375 (start_psymtab): Allocate the symfile name in the psymtab on
4376 the psymbol_obstack, rather than using the caller's storage.
4377 (end_psymtab): Only allocate a dependencies list if there are
4379 (psymtab_to_symtab_2): Use BFD when reopening file to read
4380 its symbols for real.
4381 (read_struct_type): Add FIXME comments where it needs work
4383 (read_huge_number): Add FIXME about overflows.
4384 (read_range_type): Add FIXME about comparing a long to 1<<32.
4386 * coffread.c: Minor changes to move things closer to the new
4387 regime with symtab.c and dbxread.c Major work is still needed
4390 * exec.c (exec_file_command): Remove old variables (see core.c
4392 (xfer_memory): If memory transfer is right at the end of a
4393 section, don't lose.
4395 * findvar.c (get_saved_register): If value is in a real
4396 register, LVAL is lval_register, not lval_memory.
4398 frame.h: Declare print_sel_frame and record_selected_frame.
4400 gdb-int.texinfo: New file, for GDB internals documentation.
4401 Very simple, unformatted doc of cleanups is there for now.
4403 gdbcore.h: Remove obsolete variables that described a.out
4404 section addresses and offsets. (See core.c above.)
4405 Declare fetch_core_registers and registers_fetched.
4407 getopt.c: Declare char *alloca(); even on SPARC.
4409 infcmd.c (run_command): Call target_kill rather than
4411 (step_command, next_command, stepi_command, nexti_command):
4412 Declare from_tty parameter even though we don't use it.
4413 (run_stack_dummy): argument BUFFER is a char array, not
4414 a pointer to REGISTER_TYPE.
4415 (finish_command): using_struct_return needed a value *,
4416 not a struct symbol *.
4418 * infptrace.c (child_xfer_memory): To avoid dependency on
4419 where sections are in memory, try PT_WRITE_D and if that fails,
4420 try PT_WRITE_I. Most Unixes don't care which you use.
4422 * infrun.c (step_resume_break_shadow): Change to array to
4423 match other breakpoint shadow storage.
4424 (clear_proceed_status): Pass address of bpstat to
4425 bpstat_clear, not the bpstat itself.
4426 (child_create_inferior): FIXME comment about if the child
4428 (start_inferior): Remove old function.
4429 (child_open): Use target_kill rather than kill_inferior.
4430 (wait_for_inferior): Ditto.
4431 (insert_step_breakpoint, remote_step_breakpoint): Use
4432 new step_resume_break_shadow.
4434 * inftarg.c (child_wait): If all child processes die,
4435 pretend that the one being waited for exited with signal 42.
4437 * main.c (command_line_input): When scanning for comments,
4438 don't coredump on unclosed quotes.
4439 (quit_command): Use target_kill rther than kill_inferior.
4440 (_initialize_main): Rename class_user from "user" to
4443 * printcmd.c (print_command_1): Initialize "fmt" if no format
4444 is specified by the user.
4445 (print_frame_args): Only add to args_printed if we are
4446 actually fetching args from the stack (avoiding undefined
4448 (_initialize_printcmd): Remove bogus \{ from string.
4450 * remote-eb.c (eb_open): Avoid coredump on no argument.
4452 * remote-nindy.c: Bring out of Intel environment into new
4453 target environment. Remove all conditional compilation on
4454 I80960. Massive hacking throughout.
4455 (nindy_xfer_inferior_memory): New routine stolen from
4457 (nindy_create_inferior): New routine pieced together, probably
4458 not quite working yet.
4459 (nindy_ops): New target_ops struct for nindy.
4461 * remote-vx.c: Use write_memory rather than target_write_memory
4462 to get error checking.
4463 (vx_add_file_command, vx_open): Use symbol_file_add rather than
4465 (vx_create_inferior): Use target_terminal_ours...
4467 * signame.c (_initialize_signame): Always initialize, since
4468 we need the table for things other than psignal.
4470 * solib.c (solib_add): Use symbol_file_add, not add_file.
4471 (solib_address): Return boolean result rather than struct
4472 pointer which nobody else knows the type of.
4474 * sparc-tdep.c, valops.c: Use write_memory rather than
4475 target_write_memory, to get error checking.
4477 * stack.c (locals_info, catch_info, args_info,
4478 get_selected_block, frame_command, up_command): Use
4479 target_has_stack, rather than have_inferior_p or
4482 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
4484 * symfile.h: New file, defining the interface between the
4485 generic and object-file-specific symbol reading code.
4487 * symtab.c: Move generic symbol-reading interface to symtab.c,
4488 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
4489 table to map BFD targets to symbol-reading modules in GDB.
4490 Change index to strchr.
4491 (lookup_struct_elt_type): Use error() rather than hand-made
4492 simulations thereof.
4493 (lookup_partial_symbol): Speedup slightly when length == 0.
4494 (symbol_file_add): New function.
4495 (symbol_file_command): Call it.
4496 (symfile_open, symfile_init): New function.
4497 (add_file_target_command, add_file_addr_command): moved from
4500 * target.c (target_command): use target_kill.
4502 * target.h (target_files_info): Don't declare, never called
4505 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
4506 files to determine stack end address.
4508 * valarith.c (value_x_binop, value_x_unop): Change error message
4509 to be more useful. Pass proper argument to value_struct_elt.
4511 * valops.c (value_assign): FIXME comment that long long
4512 bitfields will break here.
4514 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
4515 Update `make saber_gdb' to work better.
4517 * TODO: A woman's work is never done.
4519 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
4520 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
4521 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
4522 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
4523 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
4524 valops.c, valprint.c, exec.c: Lint.
4527 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
4529 Continuing Intel 960 port merge of GDB.
4531 * Makefile.dist: Merge i960 "nindy-share" files. Rename
4532 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
4533 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
4534 Wack over "make depend" so it handles files in subdirectories
4535 vx-share, nindy-share, bfd, and in the current directory.
4537 * blockframe.c (get_prev_frame_info): Remove fatal error
4538 if stack not defined.
4540 * core.c (core_open, core_detach): New functions that handle
4541 the old "core-file" command as "target core" and "detach" instead.
4542 (core_file_command): Call them.
4543 (core_xfer_memory): Use common routine xfer_memory.
4545 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
4546 dbxread now uses bfd for everything but symbol reading itself.
4547 BFD internals are used to drag out the relevant file offsets.
4548 (partial_symbol_file_open): Change args all around for BFD.
4550 * symtab.c: Rename "value" to "val" everywhere, so we can
4552 (symbol_file_command): New command, moved from dbxread.c
4553 and coffread.c. It uses BFD to read the file, then vectors
4554 based on its type, to dbx or coff symbol readers.
4555 * symtab.h: Extern a few vars for symbol_file_command.
4557 * target.h: Breakpoint takes a char * save area, not a char **.
4559 * valprint.c (val_print): When unpacking bitfields, offset
4560 the address in gdb of the value, if it is declared with a shorter
4561 type. Remove the last "runtime kludge test" of host byte order.
4563 * utils.c: Remove old my_bfd_read routine.
4565 * stack.c (frame_info): Use target_has_stack. Print program counter
4566 register's actual name rather than "pc", since it's called the
4567 "ip" (instruction pointer) on the i960 (sigh).
4569 * target.c (target_command): Add command for selecting a target
4570 type and calling its open routine. This is used for initiating
4571 communication with a particular target, in a generic way.
4573 * tm-i960.h: Update for modern gdb. Remove semicolons from
4574 various macros. Handle reading struct return convention, and
4575 error-out attempts to return structs with the "return" command.
4576 Be sure gdb doesn't think we know how to call functions in the
4579 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
4580 to i960_xxx in lower case.
4581 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
4582 not being defined yet.
4584 * remote.c (remote_open): Call start_remote to initialize
4585 wait_for_inferior during open.
4586 (remote_xfer_inferior_memory): Return length written rather
4589 * remote-vx.c (target_command -> vx_open): Use new generic
4591 * remote-eb.c, inftarg.c, exec.c: ditto.
4593 * infrun.c: Fix comments.
4594 (attach_program -> child_open): Use new generic target command.
4595 (wait_for_inferior): Clear saved register values before target_wait,
4596 so target_wait can set some of them if convenient.
4598 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
4599 Return success indicator, not void.
4600 (child_xfer_memory): Avoid fetching initial word if we'll
4601 overwrite it anyway.
4603 * infcmd.c (attach_command): Use new generic target open routine.
4604 (_initialize_infcmd): Update doc on attach and detach commands.
4605 (do_registers_info): Merge in a byte-order problem as a FIXME
4608 * findvar.c (find_saved_register): Avoid problem in current frame.
4609 (read_relative_register): Ditto.
4610 (write_register): Convert byte order on the way out.
4612 * exec.c (file_command): Add.
4613 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
4614 (xfer_memory): Common function between core_xfer_memory and
4616 (exec_xfer_memory): Use it.
4618 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
4620 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
4621 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
4622 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
4624 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
4626 Merge Intel 960 port of gdb, continuing...
4628 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
4629 symbol_file_command): Pass from_tty arg to hush 'em up.
4631 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
4632 Add magic numbers for 960 COFF format.
4634 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
4636 Merge Intel 960 port of gdb, from Intel "1.2" release.
4638 CHANGE_LOG entries from their port, which was based on
4641 Thu Sep 6 11:02:22 PDT 1990
4642 Remove temp file if download is interrupted.
4644 Wed Aug 1 09:08:33 PDT 1990
4645 Now uses binary protocol to talk to NINDY.
4646 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
4647 Times out after 5 seconds when trying to talk to NINDY.
4649 Tue May 29 12:54:49 PDT 1990
4650 Added variable baud rate (-b switch).
4651 Source code reorganization.
4653 Thu Apr 26 11:09:55 PDT 1990
4654 More cleanup of batch mode; specifically, execute "-s", "-e", and
4655 "-se" switches as soon as they are encountered on the invocation line.
4657 Fri Apr 20 13:47:15 PDT 1990
4660 Thu Apr 19 09:54:28 PDT 1990
4661 Add 'reset' command.
4663 Wed Apr 18 09:48:07 PDT 1990
4664 After opening remote tty, wait for 1 second to go by without input
4665 from it before trying to talk to NINDY (fixes problems with the
4666 Heurikon HK80/V960E).
4668 Mon Apr 4 16:33:05 PDT 1990
4669 Some output was not being suppressed in 'batch' mode.
4671 Thu Mar 22 15:31:11 PST 1990
4672 Ask user if old symbol table should be deleted when new file is
4675 Allow user to run a program downloaded before gdb960 was brought up.
4677 Correct "exec-file" help message for i80960 context.
4679 Correct bug in calculating user space address: could occasionally
4680 corrupt user program.
4682 Make sure to zero low-order bits in rip's because of bug in 960CA
4683 A-step part: could cause operation faults when "next"ing across
4686 Correct bug that made it impossible to get source line numbers for
4687 code loaded at addresses higher than 0x7fffffff.
4689 Wed Jan 10 12:43:22 PST 1990
4690 Open remote tty for exclusive use.
4692 Fri Jan 5 12:14:42 PST 1990
4693 Correct disassembly (CA manual was right after all):
4694 opcode for sysctl is 0x659
4696 Mon Oct 23 12:03:04 PDT 1989
4697 Use G960BASE and G960BIN environment variables to find 'sx' utility.
4699 Mon Oct 16 14:15:09 PDT 1989
4700 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
4702 Mon Oct 2 15:56:31 PDT 1989
4704 Added 960CA disassembly support.
4706 To simplify maintenance:
4707 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
4709 - eliminated opcode.h: incorporates tables into i960-pinsn.c
4710 - moved 960-specific routines from i960-pinsn.c to i960-md.c
4711 - made disassembly interface identical to that in gdmp960.
4715 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
4717 * target.h: Allow targets to stack. Add target_has_memory,
4718 _registers, etc. Restructure memory access and "info files"
4719 to walk the target stack.
4720 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
4721 target.c: Change tables to match target.h.
4722 * inflow.c (child_mourn_inferior): pop child_ops.
4723 (generic_mourn_inferior): Use new has_stack flag.
4724 * infptrace.c (child_xfer_memory): New memory regime.
4725 * inftarg.c (child_files_info): New "info files" regime.
4726 * remote-eb.c: New memory regime, new info files.
4727 * remote-vx.c: New memory regime, new info files. Now use
4728 separate targets for VxWorks attachment to machine, and
4729 actually running a process under VxWorks, since one has
4730 stack & execution & regs and the other doesn't.
4731 * remote.c: New memory regime, new info files.
4732 * sparc-xdep.c (fetch_core-registers): New memory regime.
4733 * target.c: New routines and support for stacked targets,
4734 new memory regime, new info files regime.
4737 Generalize section handling for an arbitrary number of sections,
4738 including use of the new BFD (binary file) library.
4739 * gdbcore.h: Add struct section_table.
4740 * exec.c (build_section_table): Iterate all sections and
4741 record what gdb needs to know about them.
4742 (exec_command): Use it.
4743 (exec_xfer_memory): Use the table.
4744 (exec_files_info): Print the table.

4747 * source.c (find_source_lines): Use bfd_get_mtime.
4748 * dbxread.c: Quick changes to make it compile with new BFD.
4749 * utils.c (error): Avoid using bfd_error in generic routines.
4751 * core.c (core_fetch_registers): Get from the ".regs" section of
4753 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
4755 * inferior.h (attach_flag): Export.
4756 * infcmd.c (run_command): use new target_create_inferior.
4757 * infrun.c (child_create_inferior): Don't return result.
4758 * Makefile.dist (VERSION): 3.91.4.
4760 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
4762 * breakpoint.c (bpstat_num): Handle breakpoints which have
4763 since been deleted, such as temporary breakpoints.
4764 infcmd.c (program_info): ditto.
4766 * core.c (core_file_command): Display the frame where the core
4771 * remote-vx.c (target_command): Merge in target command from
4772 targ-vx.c. A few other cleanups.
4774 * TODO, Projects: Lots more stuff to do...
4776 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
4778 Massive changes to wall off the remote-debugging interface
4779 behind a function vector. The port to handle VxWorks targets
4780 is also part of this.
4782 All files: Replace references to renamed functions,
4783 remove references to remote_debugging, remove references to
4784 have_include_file, have_core_file in favor of target_has_stack,
4785 target_has_memory, etc.
4787 * Modularize the breakpoint interface.
4788 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
4789 a breakpoint instruction.
4790 breakpoint.c: struct breakpoint's shadow_contents now sized as
4792 (insert_breakpoints): Vector to target to install breakpoints.
4793 (remove_breakpoints): Vector to target here too.
4794 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
4795 sparc-tdep.c (single_step): Use new breakpoint interface for
4796 the single-step breakpoints.
4797 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
4798 New file, contains routines to insert and remove breakpoints by
4799 reading out the old contents and later replacing them. This is
4800 how ptrace breakpoints work, and many remote systems as well.
4802 * tm-vxworks68.h: New config file, overrides a few things for
4803 Wind River's preferences.
4805 * target.h: New file, for transfer vector used to talk to the
4806 inferior (child, attached, core, exec, remote, etc). All accesses
4807 to the thing being debugged should come through these vectors.
4808 target.c: New file, routines to handle transfer vector.
4809 (various files): Add transfer vectors XXX_ops for the various
4810 targets and pseudo-targets (core files, etc) we support.
4812 * breakpoint.c (bpstat_stop_status): Further explorations of
4813 watchpoints and why things don't work all the time.
4814 (bpstat_alloc): New fn to allocate a bpstat and chain it.
4816 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
4817 the local gdbinit if it doesn't already have it.
4819 * core.c (core_ops): add and install.
4820 Allow core debugging without exec file.
4822 * dbxread.c (free_and_init_header_files): Merge two fns.
4823 (end_symtab): Free named symbol table when a new version comes in.
4824 (read_dbx_symtab): Relocate all kinds of symbols with base
4825 address. First step toward handling different text, data, bss
4827 (add_file_addr_command): Renamed add_file_command.
4828 (add_file_command): Vector to remote handler.
4829 Add "load" as an alias for "add-file" command.
4831 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
4832 non-returning functions.
4834 * exec.c: Add exec_ops, and push it as a target when an exec
4837 * infcmd.c (run_command): Pass executable file name and arg list
4838 separately when starting an inferior. Permit "run" when no exec
4839 file is specified, for VxWorks.
4840 (detach_command): Move to child_detach in inftarg.c.
4842 * inftarg.c: New file. Unix-child-specific routines, and the
4843 child_ops structure.
4845 * inferior.h (registers): Export "registers" as the way for
4846 target dependent register handlers to find gdb's local copy of
4847 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
4848 since it is now used by places that want wait_for_inferior to
4849 handle the grunge but want to see every trap from the inferior.
4851 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
4852 Eliminate remote_debugging hooks in terminal handling.
4854 * infrun.c: Replace start_inferior with child_create_inferior.
4855 Move all the hair of Unix shells and ptrace idiosyncracies into
4856 child_create_inferior, so remote handlers don't have to deal.
4857 Remove running_in_shell. Rename stop_after_attach to
4858 stop_soon_quietly, and use it in a few other places where we want
4859 to just call wait_for_inferior and get control back on the first
4860 trap. trap_expected now never takes a value > 1.
4861 (init_wait_for_inferior): Initialize static vars when a new
4864 main.c (gdbinit): Add new hook for .gdbinit file name, let
4865 it be overridden by config files as GDBINIT_FILENAME.
4866 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
4867 Both of these are used for VxWorks gdb.
4869 mcheck.c: rename include file "gmalloc.c" to avoid problems
4870 with system include file "malloc.c".
4872 param-no-tm.h: New include file, same as param.h but does not
4873 include the default "tm.h" file. This is used in files where
4874 the target is known, e.g. remote-eb.c or sparc-xdep.c.
4876 param.h: Now just a shell that includes tm.h and param-no-tm.h.
4878 remote-vx.c: New file, VxWorks remote debugging support. Uses
4879 RPC routines that are shared with the target system, in directory
4882 remote.c: Vectorize remote interface.
4884 source.c: Globalize source_path, and make an alias "l" for "list"
4885 since we now have the "load" command.
4887 sparc-xdep.c: Use new param-no-tm.h.
4889 symmisc.c (free_named_symtab): Add new function from Wind River.
4890 However, ifdef it out for now while we think about what it should
4893 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
4895 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
4896 non-Unix-children handle this with their own code in the target
4899 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
4900 source and target lists. Add vx-share to default list of include
4901 directories. Add new files to src and target lists: mem-break,
4902 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
4903 ${srcdir} versions of munch and createtags are used.
4905 * valops.c (find_function_addr): Split out of call_function.
4906 (call_function_by_hand): Rename call_function; this function
4907 calls functions in the target by laboriously patching the target
4908 word-by-word with the right stack, args, regs, etc.
4911 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
4913 Handle AMD 29000 a bit better.
4915 * remote-eb.c (readchar): Mask received char log to make it readable.
4916 (remote_start): Pass arguments down to executing program.
4917 Make startaddr unsigned.
4918 infrun.c (start_inferior): Accept args, pass them to
4920 infcmd.c (run_command): Pass args down to start_inferior.
4922 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
4923 the target object file format.
4924 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
4926 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
4927 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
4929 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
4931 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
4932 * TODO: We did a few things, we have more to do though.

4939 * sparc-tdep.c (do_restore_insn): Simplify.
4940 (sparc_frame_find_saved_regs): Simplify and fix what we find.
4941 (sparc_push_dummy_frame): Simplify and fix what we push.
4942 (sparc_pop_frame): Slightly more hair here, deciding whether
4943 we are restoring a saved PC or returning to a return address in %i7.
4944 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
4946 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
4947 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
4948 * obstack.h (chunkfun): ditto.
4949 * defs.h (xmalloc, xrealloc): ditto
4951 * utils.c (quit): Grab the terminal from the child if necessary.
4953 * inflow.c (term_status_command): Rename to term_info, change
4956 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
4957 (is_delayed_branch): Speed up.
4958 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
4959 Still missing some float ops, and needs testing.
4961 * Support for input and output radixes other than base 10
4962 * defs.h (input_radix, output_radix): Declare.
4963 * expread.y (yyparse, parse_number): Handle changes of input
4964 radix, and ambiguous names-or-numbers in radixes >10.
4965 * printcmd.c (print_scalar_formatted): Print formatted hex
4966 numbers in varying column widths.
4967 * valprint.c (val_print): Use output_format to print scalar ints.
4968 (set_input_radix, set_output_radix, set_radix): Create.
4969 (set_output_radix): Set output_format from output_radix.
4970 (_initialize_valprint): add `set radix' but leave the others off.
4972 * main.c (execute_command): Let stupid questions be turned off.
4973 (_initialize_main): Handle "set stupidity", etc.
4975 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
4976 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
4978 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
4980 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
4981 bfd stuff is still screwed up, but with some manual work, it
4984 * breakpoint.c (bpstat_do_actions): Start over if a command
4985 proceeds the inferior, since the inferior will have stopped and
4986 will need to have its new stop-actions taken care of.
4988 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
4989 compiler fits, simplify it.
4991 * gdb.texinfo (directory command): Doc new dir command.
4992 source.c (directory_command): "dir" now puts things on the front
4993 of the path, moves dups up front, and handles multiple names
4994 on the command line, inserting each one in order. It also
4995 blows away cached line and full_filename info.
4997 * stack.c (backtrace_command): Skip "more stack frames follow"
5000 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
5001 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
5002 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
5003 The only odd one was Gould NP1, which had defined vprintf to
5006 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
5007 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
5008 variable, inspect_it.
5009 valprint.c (print_string, val_print): Use the global inspect_it
5010 to indicate whether to print in Epoch style or normal style.
5012 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
5014 * printcmd.c (call_command): add an alias for the "print" command
5015 which runs expressions and doesn't print the result if void.
5016 (print_command_1): implement it.
5018 * command.c: Remove #if 0'd code. Initialize all the fields
5019 in add_cmd (). Rename do_nothing_command to
5020 not_just_help_class_command, and make it externally visible.
5021 command.h: add user_commands to struct.
5022 * main.c (define_command): Don't overload c->function with a char
5023 string as well as a function pointer.
5025 * eval.c (evaluate_subexp): Reinstall tiemann changes to
5026 calling convention of value_struct_elt () that got dropped in
5029 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
5030 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
5032 * tm-sparc.h (POP_FRAME): replace some constants with defines.
5034 * sparc-xdep.c (store_inferior_registers): defer stores to regs
5035 until a good time (e.g. when we are about to run the child),
5036 saving ptrace calls.
5037 * infrun.c (proceed): handle DO_DEFERRED_STORES.
5038 * tm-sparc.h: define DO_DEFERRED_STORES.
5040 * sparc-xdep.c (store_inferior_registers): when storing float
5041 registers, don't store stack regs too. When storing the SP,
5042 however, DO store the stack regs too. This fixes a bug in which
5043 the dummy frame is not recognized when a call_function finishes,
5044 because its frame pointer (in the stack regs) was never
5046 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
5047 even though we don't know how to read them from an inferior.
5048 valops.c (call_function): Comment about storing SP.
5050 * infrun.c (save_inferior_status): Save away the original bpstat
5051 chain so it can be restored later. Install the copied version for
5052 use by whoever saved the status. It will be blow away by
5053 restore_inferior_status, and the original chain restored. This is
5054 important for people who have pointers into the original.
5056 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
5057 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
5058 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
5061 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
5063 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
5064 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
5065 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
5067 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
5069 * Merge Mike Tiemann's multiple inheritance changes from Sun.
5070 Store the baseclasses in a type struct starting from array element
5071 0 rather than from the unusual array element 1.
5073 dbxread.c: the above.
5074 (virtual_context): Add
5075 Read new debug information about which virtual function table
5076 a virtual function is from, and store it in fn_field.fcontext.
5078 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
5079 TYPE_FN_FIELD_STATIC_P.
5081 symtab.c: the above.
5082 valops.c: the above. Handle pointer casts of object *'s.
5083 (search_struct_method): Add.
5084 (value_struct_elt): First arg is now a pointer to a value, and is
5087 valprint.c: the above.
5088 values.c (value_virtual_fn_field): Add type arg. Handle
5089 offsetting to the proper object when calling virtual fns.
5091 (baseclass_addr): Add valuep arg.
5093 * README: Document the current state of BFD config (missing).
5094 * TODO, ChangeLog, Makefile.dist: Roll version.
5095 * WHATS.NEW: Add summary of changes since 3.5.
5097 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
5099 * dbxread.c (read_struct_type): Clear bit vectors whenever
5101 symtab.c (B_CLRALL): define.
5103 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
5104 using == rather than =. Huh... This fixes the dreaded problem
5105 wherein builtin_type_int becomes TYPE_CODE_FLT.
5107 * core.c (info_files): Show the inferior pid.
5109 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
5110 already knows how to look in the source directory.
5112 * Remove psymtab hair from many places. Remove duplicated code
5113 for searching symbol tables. Hide psymtabs from most places.
5114 Make it fast to get from a psymtab to its symtab.
5116 blockframe.c (blockvector_for_pc): Remove psymtab hair.
5117 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5118 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5119 dbxread.c: export psymtab_to_symtab, make it work if called N times.
5120 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
5121 new symtab completely. New psymtabs get symtab pointer
5122 initialized to zero. Remove MI warning printf.
5123 symtab.h: Comments. Add psymtab to symtab pointer.
5124 (PSYMTAB_TO_SYMTAB): New macro.
5125 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
5126 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
5128 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
5130 (print_frame_info): Avoid special-casing symbols that have not yet
5133 * source.c (open_source_file): Quick path if we have already
5134 located the source file by its full name.
5136 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
5137 find_pc_psymtab. When a name is found in the misc function
5138 vector, search the symbol table for its mangled name, not the
5139 name that the user typed.
5141 * bfd.h: Fix missing comment terminators, make #endifs match.
5143 * valarith.c (value_less): Handle unsigned int comparisons.
5144 Add FIXME about pointer compares, which assume host and target
5145 pointers are the same.
5147 * command.c (do_nothing_command): lint
5148 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
5149 fix comments on debug symbol format for visibility. Actually set
5150 visibility of symbols.
5151 main.c (echo_command): lint; use <readline/history.h>.
5152 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
5153 obstack.h (_obstack_blank): Rearrange pointer math to avoid
5154 pointing past end of allocated memory; saber complains.
5155 obstack.h: Declare the external functions that we use.
5156 valarith.h: use <string.h>
5157 solib.c (solib_add): lint.
5159 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
5161 * main.c (initialize_main): Default info_verbose to off, now that
5162 symbol reading is fast.
5163 (quit_command): Avoid clobbering exec_bfd while quitting.
5165 * Initial BFD (binary file diddling library) merger:
5166 coffread.c: Change AOUTHDR to struct exe_hdr.
5168 core.c: initialize initialized data at compile time.
5169 (core_file_command): Move from coredep.c, convert to bfd.
5170 (xfer_core_file): Convert to bfd.
5171 exec.c (exec_file_command): use bfd routines.
5173 mips-tdep.c: Remove exec_file_command and friends.
5176 * coredep.c: (fetch_core_registers) Convert core_file_command to
5177 fetch_core_registers.
5178 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
5180 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
5181 (my_bfd_read): More bogosity, which I don't think we call.
5182 (program_name): Remove this atrocity asap!
5184 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
5187 values.c: allocate_repeat_value was not clearing the
5188 optimized_out field.
5189 (value_static_field): minor stylistic fix (wrong macro was used).
5190 valops.c (value_struct_elt_for_address): didn't work for C++
5193 * signame.c (_initialize_signame): Initialize signal names once.
5195 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
5196 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
5197 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
5199 * remote-eb.c: Support user-settable baud rates on the serial port.
5201 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
5203 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
5205 * tconfig/sun3os4: Remove warning about native assembler,
5206 since it also occurs in the xconfig file.
5208 * findvar.c (registers): Allocate some slop after `registers'
5209 to prevent stray accesses from trashing the next variable.
5211 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
5212 on the sun-3, by changing the #ifdef from `sun3' (which is not
5213 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
5214 vars, which happened to follow `registers' in the executable.
5216 * readline/history.c (history_search): Heed gcc-2's advice
5217 and parenthesize && inside ||).
5219 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
5220 tm-29k.c: Insert FSF copyright headers.
5222 * remote-eb.c: Better comments.
5224 * Makefile.dist: Update to 3.91.6.
5225 * TODO: note PREPARE_TO_STORE problem.
5227 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
5229 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
5231 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
5233 * infrun.c (wait_for_inferior, at end): Don't set up
5234 prev_* if the inferior no longer exists.
5236 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
5237 CANNOT_EXECUTE_STACK.
5238 valops.c (call_function): Use it.
5240 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
5242 * inferior.h (PC_IN_CALL_DUMMY): New macro.
5243 infrun.c (wait_for_inferior, 2 places): Use it.
5245 * values.c (value_being_returned): Only use
5246 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
5248 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
5249 right thing for remote-eb.c.
5251 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
5252 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
5254 * blockframe.c: Put get_frame_saved_regs inside #if !defined
5255 (FRAME_FIND_SAVED_REGS).
5257 * findvar.c ({fetch,store}_registers): Check for
5258 REMOTE_{FETCH_STORE}_REGISTER macro.
5260 * findvar.c (get_saved_register): Add argument lval and
5261 change meaning of argument addr.
5262 findvar.c: Change calls to get_saved_register to reflect
5263 new calling convention.
5264 valops.c (value_assign): Use get_saved_register instead of
5265 find_saved_register.
5267 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5269 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
5270 an (uninitialized) pointer to one. Use "&" when passing it
5273 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5275 * coffread.c (getfilename): Use DGUX x_offset and x_name if
5278 * coffread.c (symbol_file_command): Put semicolon after
5280 Put safe_to_init_tdesc_context in #if defined (TDESC).
5281 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
5282 coffread.c: #include <sys/stat.h>.
5283 (read_coff_symtab): Typo: in_source_files -> in_source_file.
5284 Add missing ')' in check for "lc%" and friends. Remove
5286 Declare read_one_sym() at top of file.
5287 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
5288 MC68WRMAGIC can have the same value without causing a duplicate
5291 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
5293 * Allow a Makefile to be built without building the
5294 tm and xm file links that screw up builds in subdirectories.
5295 This is done with `config.gdb none', then you can do things
5296 like `make gdb.tar.Z'.
5297 * tconfig/none: Config file for no target system
5298 * xconfig/none: Config file for no host system
5299 * config.gdb: If no TM or XM files are called out by the
5300 host or target file, don't make links for them.
5302 * cplus-dem.c: Add documentation.
5304 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
5305 simple error, so the user's gdb doesn't crash due to some object
5306 file problem (e.g. somebody is rebuilding the file out from under
5309 * printcmd.c (print_address_symbolic): demangle the symbol.
5311 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
5312 Motorola copyrights in it. Make "make gdb.tar.Z" work.
5313 (alldeps.mak): sort and uniq all results from this; duplicates
5314 hose gdb.tar.Z link building. Remove RCS files from
5315 tconfig and xconfig. Add config files for sun386. Add
5316 a few odd files to OTHERS and HFILES.
5318 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
5320 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
5321 Roll version number to 3.91.5. Make lint work in bindir.
5323 * README: Document cross-debugging and new file structure.
5325 * blockframe.c: Lint. Include "value.h" to declare read_register.
5326 (find_pc_partial_function): remove duplicate line.
5328 * command.h: Lint. Declare error_no_arg and dont_repeat.
5330 * tm-news.h: Remove inadvertently duplicated stuff.
5332 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
5333 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
5335 * config.gdb: Allow `config.gdb host target' form. Clean
5336 up previous change that printed bogus messages when you just said
5339 * core.c: #include "command.h" for lint.
5342 * main.c: Remove some casts of enums. Lint.
5349 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
5351 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
5352 read it from memory. This will allow us to save ptrace calls
5353 eventually. Changed caller single_step too.
5355 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
5356 that we aren't going to use, saving many ptrace calls, especially
5357 when watchpointing or single stepping. Use some #define's for
5359 (store_inferior_registers): Ditto.
5360 (core_file_command): Use some #define's for constants.
5362 * tm-sparc.h: Add #define's for some register numbers, so we
5363 can eliminate the use of random constants in sparc-xdep.c.
5365 * stack.c (frame_command, print_frame_info, up_command,
5366 down_command) Remove frame_changed, since it
5367 causes a bug and doesn't seem to do anything useful. In some
5368 places it was used as a flag, in others as a stack level (?).
5370 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
5371 default is to use the portable (vprintf) version rather than the
5373 * xm-news.h (MISSING_VPRINTF): Add.
5375 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
5377 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
5379 * Remove stuff that forces -Bstatic linking of gdb, and warnings
5380 about linking debugged programs -Bstatic in the sun?os4 config
5381 files in tconfig and xconfig subdirectories.
5383 * main.c (main): Remove unreached exit(0) now that we exit
5386 * Create TODO file for online bug list. There are too many
5387 "little" bugs to keep track of on paper.
5389 * Change Projects file to refer to bug-gdb@cygnus.com
5390 rather than kingdon@ai.
5392 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
5394 * Makefile.dist (VERSION): 3.91.4 now.
5396 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
5397 (condense_misc_bunches): Add sanity check that misc_count is
5398 the same as the number of symbols in the bunch.
5400 * coffread.c: rename init_misc_bunches. Pass an argument
5401 to condense_misc_bunches (a zero).
5403 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
5404 every time we are called; don't rely on our caller to do it.
5405 (add_file): Remove call to init_misc_bunches.
5407 * mipsread.c: Only warn, don't error, if unknown symbol types.
5408 This keeps an old gdb from falling on its face if it sees newly
5409 extended symbol info. Rename init_misc_bunches.
5411 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
5413 * Merge in changes from Per Bothner for DECstations and other
5414 MIPS stuff. The rest is Bothner speaking:
5416 The next message is a merger of Alessando Forin's mips port with
5417 mine. I've tried to use my good if biased judgment to get
5418 the best of both. It *does* need testing.
5420 Some of the changes are general, *not* mips-specific.
5423 Didn't believe in little-endian bit order.
5424 There are still inconsistencies about whether flags
5425 like BITS_BIG_ENDIAN are integer (#if ...) or
5426 boolean (#ifdef ...). I tried to paper over them.
5428 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
5429 Moved some misc_function code that was common to
5430 {dbx,coff,mips}read.c to symtab.c.
5431 In the process, I think I cleaned things up a bit.
5432 At the same time, moved obsavestring and obconcat to symtab.c.
5435 Removed obsolete condense_addl_misc_bunches (use
5436 condense_misc_bunches(1) instead).
5439 Needed to include <sys/dir>, at least on DECstations.
5441 valops.c, mips-tdep.c, tm-mips.h:
5442 Added PUSH_ARGUMENTS macro to support funny argument-pushing
5443 conventions (when STACK_ALIGN is insufficient).
5444 Needed on mips, where doubles need 8-byte alignment,
5445 but ints only need 4.
5448 Removed cruft that was not being used.
5449 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
5452 Print $ before register-names (I think that makes things a little
5454 Never print two instructions, even if one delays.
5455 Removed hex-disassemble set_cmd. (This is not mips-specific,
5456 so I think the argument is whether it is generally worthwhile or not.
5457 I'm inclined to think not, given how easy it is to
5458 convert between radixes in gdb.)
5461 This is basically Alessando's code.
5462 It doesn't use obstacks; I changed it to use obstacks
5463 in a few minor places where using malloc causes a
5464 memory leak. (Probably, more places could/should be changed.)
5465 I added record_misc_function where it was missing.
5466 In symbol_file_command and add_file_command, I tried
5467 to make the code consistent with more recent versions.
5468 Minor sylistic changes in parse_procedure.
5469 Make a .gdbinfo. psuedo-symbol point back to the real
5470 procedure symbol (using the isym field).
5473 This is basically from my port, but with a lot of details
5474 and a number of routines merged in from Alessando's version.
5475 I basically used my code "raw" backtrace (use heuristics
5476 from the actual code, rather than symbol table info) - though
5477 the idea is Alessandro's. I feel my code is a little cleaner
5478 here, particularly in being a little more flexible, such as being
5479 able to handle gcc-produced code (which it now can).
5480 It also doesn't do frame caching (which is not useful
5481 more recent gdb versions).
5482 I also used my code for push_/pop_dummy, more or less.
5483 I tried to incorporate AF's code for testing sigtramp
5484 while backtracing; I probably got it wrong.
5485 Added mips_print_register, which tries to scrunch as much
5486 information as possible on a screen...
5487 Removed the skip-prologue set_cmd. As with hex-disassemble (see
5488 under mips-pinsn.c), I don't see anything mips-specific here,
5489 and I don't see it being all that useful anyway.
5492 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
5493 Use more register names (rather than hard-cases numbers).
5495 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
5497 * Hack up 3.90.11 changes:
5499 * Makefile.dist (depend): parameterize $(GCC).
5500 Add solib.c and solib.o.
5501 (readline): Fix vpath for both absolute or relative SRCDIR.
5503 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
5504 Also, let the part I didn't understand at least compile so
5505 I can test the rest. FIXME.
5507 * dbxread.c: Fix thinko using strcmp.
5508 (init_psymbol_list): declare static.
5509 (partial_symbol_file_open): Comment cleanups better, avoid
5510 cleaning up the string table since the caller will do that.
5511 Move the stat for mod time into symbol_file_command, temporarily.
5512 (There should be a mod time for each symbol file, eventually,
5513 to control its rereading. FIXME.)
5515 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
5516 SunOS, which gives error for shared libs otherwise. (From
5517 Schaefer, probably FIXME needs work for portability.)
5519 * solib.c: Move #include "param.h" to work.
5520 Lowercase all the Uppercase Letters In the Messages.
5521 (find_solib): Clean up inferior_so_name for debug printouts.
5522 Allow no argument, to mean all shared libraries.
5524 * symmisc.c: include param.h to get CLEAR_SOLIB.
5526 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
5528 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
5529 to 3.90.11. ChangeLog entries below are from this.
5531 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5535 * Makefile.dist (HFILES): Add tm-sunos.h.
5537 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5541 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
5543 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
5545 * sparc-opcode.h Added single-operand version of rett.
5547 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5549 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
5550 Put parens around gcc_p in expansion.
5552 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5554 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
5556 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5558 * Changes for Sun shared libraries:
5559 blockframe.c (find_pc_partial_function): If a non-text symbol
5560 is found, set *address = pc - FUNCTION_START_OFFSET.
5561 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
5562 Disable breakpoints instead of giving an error.
5563 source.c (select_source_symtab): Initialize cs_pst.
5564 symmisc.c: Call CLEAR_SOLIB if defined.
5565 symtab.h: Make text{low,high} CORE_ADDR not int.
5566 (psymtab): New field addr.
5568 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
5569 (record_misc_function): Give correct type for N_DATA symbols.
5570 (condense_misc_bunches): do "misc_function_count = j" regardless
5572 Take code which is shared between symbol_file_command and
5573 add_file_command and put it into partial_symbol_file_{open,read}.
5574 Split add_file_command into add_file_command and add_file.
5575 Make psymtab_to_symtab read in the string table if the file
5577 Two new parameters to read_dbx_symtab and start_psymtab.
5578 tm-sunos.h: New file.
5580 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5582 * infcmd.c: Change cont_command to continue_command and "cont"
5585 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5587 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
5589 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
5591 * values.c (USE_STRUCT_CONVENTION): Check for structures of
5592 size 1,2,4,8 rather than size < 8.
5594 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
5595 as necessary, not just once.
5597 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
5599 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5601 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
5603 * tm-news.h: Add CALL_DUMMY_*.
5605 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
5607 * config.gdb: In list_host, list_target, use ${i}, not $i.
5609 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5611 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
5613 * sparc-opcode.h: Change all store floating-point state register
5614 instructions to have the right match & lose fields.
5616 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5618 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
5620 config.gdb: If srcdir != ., create readline directory and
5621 copy a makefile into it.
5623 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
5624 consistency with POSIX.
5626 * breakpoint.c (bpstat_stop_status): Disable watchpoint
5627 when we exit its exp_valid_block.
5629 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
5631 * Makefile.dist: Bump version to 3.91.3.
5633 * Clean up handling of breakpoint commands (somewhat).
5634 Prompted by Tiemann bug report "cont 10" doesn't work any more.
5636 inferior.h: Add breakpoint_proceeded to inferior status struct
5637 and globals; save it and restore it.
5638 (clear_breakpoint_commands): Cleanup, remove old #define.
5640 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
5641 (save_inferior_status, restore_inferior_status): handle it also.
5642 (proceed): Remove earlier code that set breakpoint_proceeded.
5643 It is now set only in clear_proceed_status.
5644 (clear_proceed_status): Cleanup, use bpstat_clear rather
5645 than clear_breakpoint_commands. No callers need the stop_bpstat
5646 between clear_proceed_status and proceed.
5648 infcmd.c: Add breakpoint_proceeded definition and comment.
5649 (cont_command, jump_command, signal_command): Move call to
5650 clear_proceed_status right next to call to proceed.
5652 breakpoint.c (bpstat_do_actions): Avoid clobbering our
5653 caller's argument while running down the chain of breakpoints.
5654 Use new variable "breakpoint_proceeded" to determine when
5655 a command that it executes moves the inferior past the
5657 (bpstat_clear): Handle NULL argument.
5658 (bpstat_clear_actions): Avoid useless call to
5659 breakpoint_auto_delete.
5660 (delete_breakpoint): Clean up bpstat's that are pointing to
5661 the deleted breakpoint from the stop_bpstat chain.
5662 (breakpoint_auto_delete): Simplify.
5664 * Clean up handling of EOF, error on stdin, etc. This was
5665 prompted by a network problem that caused gdb to go into an
5666 infinite loop filling up its malloc'd memory.
5668 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
5669 not clear_breakpoints_commands, which is now gone.
5670 (main): If command_loop returns (e.g. from EOF on stdin), do
5671 a quit_command (looping back to command_loop if quit_command
5672 doesn't really quit).
5673 (command_loop): check result from command_line_input and
5674 exit if it returns NULL, rather than passing the NULL to
5676 (gdb_readline): Free malloc'd result space before returning
5679 * utils.c (query): Handle C-d to mean "yes", just as if the
5680 input was not a terminal. Also avoid infinite loop if EOF
5681 occurs in mid-input-line before newline. This allows
5682 query to be used at EOF on stdin with reasonable results.
5684 * infrun.c (proceed): Set breakpoint_proceeded.
5686 * values.c (value_as_long): Avoid infinite recursion for enums.
5687 (_initialize_values): Fix typo in help msg (kingdon).
5689 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
5690 RL_LIB for linking. This allows -lreadline for linking
5691 and nothing for dependencies, once readline is a real library.
5693 * config.gdb: Jim Kingdon: give useful error message if the
5694 host or target type is not recognized.
5696 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
5697 it just defines it. Dumb, but deal with it.
5699 * Jim Kingdon suggests:
5700 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
5702 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
5704 * Makefile.dist (VERSION): Bump version # to 3.91.2.
5706 * Clean up Bothner's changes.
5708 * blockframe.c (clear_pc_function_cache): New function.
5709 * blockframe.c: remake cache_pc_function_* static.
5710 * dbxread.c (symbol_file_command): remove references to
5711 cache_pc_function_* variables.
5712 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
5713 * printcmd.c: Avoid kludging a global variable (addressprint)
5714 to avoid printing the address of a string twice. Instead,
5715 pass the format letter 's' down low enough that it can be seen
5716 to avoid this problem.
5717 (print_formatted): Pass format arg to value_print.
5718 (restore_addressprint): Remove function.
5719 (do_examine): Avoid hacking addressprint, cleanups and such.
5720 (print_frame_args): Add a comment to a Bothner change.
5721 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
5722 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
5723 to wipe out the values cached in blockframe.c.
5724 * symtab.c (find_method): Add comment saying how big you must
5725 allocate to be "big enough". Per being terse again.
5726 * valprint.c (val_print): Handle format letter "s" to print
5727 strings without addresses. Add comment to vtbl printing code
5728 which casts with wild abandon. Rearrange reference-printing
5730 @0xaddr: value (print w/addressprint)
5731 value (print w/~addressprint)
5732 @0xaddr (parameter lists w/addressprint)
5733 or nothing (parameter lists w/o addressprint)
5735 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
5737 * Merge more changes from Per Bothner:
5739 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
5740 annoying) that I tried to improve it. Here are my suggestions.
5742 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
5745 Do automatic de-reference when taking the address of a reference.
5747 Don't deref_ref when printing parameter lists.
5749 More attempts at treating refernences properly.
5751 In val_print, if deref_ref==0, don't print dangling " = ".
5753 Add COERCE_REF macro, which de-references an REF.
5755 * Merge changes from Per Bothner:
5757 * Fixed (Sony news)-specific configuration problems.
5758 * Fixed other problems with using vanilla pcc and libc (enum problems;
5759 assumption that vsprintf exists).
5760 * Some major speed-ups (finc_pc_partial_function now caches a match;
5761 parsing avoids duplicate symbol_lookup calls).
5762 * Changed handling of baseclasses (no longer use baseclasses field
5763 of struct type, use the first n_baseclasses fields instead).
5764 * Various minor changes/fixes, most C++-related.
5767 Cache the most previous match from find_pc_partial_function.
5768 (Save both low and high ends of matching function's pc range.)
5769 This speeds up the loop of infrun.c:wait_for_inferior quite
5770 a bit, and makes step/next commands much zippier.
5772 Added an enum->int cast (otherwise, some compilers barf).
5774 No longer set baseclass offset to 0, since multiple
5775 inheritance now mostly works.
5776 Added a number of casts, to shut up compiler warnings
5777 (after stabs where made enums, not ints).
5778 When discarding a symbol table (in symbol_file_command),
5779 must clear the cache introduced in blockframe.c.
5780 Don't convert $vtbl_ptr_type to vtbl any more.
5781 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
5782 Mask off sign bit emitted by g++ for virtual table offset.
5783 Set voffset to -1 (not 1) for static member functions.
5785 Changed parsing/lexing of names to avoid doing symbol lookup twice
5786 (once when lexing to determine symbol class, once for real).
5787 Now only call symbol_lookup once. Fields of 'this' win especially big.
5789 Subpress printing addr twice in the case of 'x/s addr'.
5791 lookup_basetype_type is no longer used.
5792 Add find_methods as recursive helper function to decode_line_1.
5793 This allows multiple inheritance to work.
5794 Also, once one or more matches has been found, do not look in
5795 base-classes. (Baseclass methods would be overridden, anyway.)
5797 Removed baseclasses array in struct type.
5798 Instead of using baseclasses[i], use fields[i-1].
5799 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
5800 Changed sign convention of voffset (previous was inconsistent).
5802 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
5804 Used to assume existence of vsprintf. Re-written to not need it
5805 if HAVE_VPRINTF is undefined.
5807 typecmp was too pessimistic. Made it less so.
5809 Don't print space after address.
5810 If vtable points to a misc symbol (with 0 offset), print it,
5811 since that indicates the actual class of the object.
5812 Changed ype_print_derivation_info to use new inheritance
5813 scheme (without baseclasses vector).
5815 In value_primitive_field, fixed some bugs left over from previous set of fixes.
5816 Also, changes needed because TYPE_BASECLASSES were removed.
5818 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
5820 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
5823 If there is no path set, and the symbols don't indicate what directory
5824 a file was compiled in, look in the current directory. But either
5825 a path or a known compilation directory will prevent this.
5828 Three independent bug fixes:
5829 * Remove the #if 0 block that breaks some stuff.
5830 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
5831 adapt gdb to either SunOS 4.0.* or 4.1.
5832 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
5835 Instantiate the class T when looking for methods in it. (Tiemann@sun)
5838 (type_print) Demangle the name being printed.
5839 (type_print_base) Handle botched demangling without coredump (tiemann).
5842 (check_stub_method): Document routine.
5843 (tiemann) fix bug for no-arg functions
5844 Avoid clobbering beyond end of malloc'd storage.
5845 Terminate the argument list properly.
5847 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
5849 * Changes merged by John Gilmore:
5852 In breakpoint_1, use new print_address_symbolic instead
5853 of find_pc_partial_function. (This forces use of assembler-level
5854 addresses, and avoids misleading non-mangled source-level names.)
5856 Generalize ansi argument such that -1 means skip arglist totally.
5857 Removed global variable print_ansi_qualifiers (which made
5858 code non-reentrant), in favor of extra explicit arguments
5859 to internal routines.
5861 Add new helper function print_address_symbolic.
5862 Use find_pc_misc_function instead of find_pc_partial_function
5863 (since we want assembler-level symbols here).
5865 Print unknown function as just "f (...)", not "f (...) (...)".
5866 Use new fputs_demangled explicitly.
5868 Fixed a typing violation (problem: value.h cannot be imported
5869 without renaming many variable in this file).
5870 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
5871 decode_line_1: Moved forward some never-reached code.
5872 Made decode_line_2 skip function prologues correctly.
5874 fputs_filtered should not demangle by default.
5875 Add new fputs_demangled to demangle on demand..
5877 Change value_struct_elt to use value_primitive_field (using recursive
5878 utility function search_struct_field). This allows foo.bar to work
5879 for multiple inheritance (so far only for data fields).
5880 Change check_field in the same way (recursive helper function
5881 to support multiple inheritance).
5882 (Note: there are more of these problems that I haven't fixed.
5883 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
5884 value_of_this: 'this' symbol name is now just "this", note "$this".
5886 Don't print static members.
5887 Avoid printing "members of <type>" if there are none.
5888 Simplified type_print_derivation_info by merging duplicate code.
5889 Remove useless blank lines in type_print_base (ptype command).
5891 Added declaration of new routine value_primitive_field.
5893 Added value_primitive_field which is generalized version of
5894 value_field that can handle multiple inheritance (non-zero offsets etc).
5895 Re-implemented value_field to call value_primitive_field.
5897 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
5899 * infcmd.c -- insert else to avoid 'delete env' coredump when you
5900 delete the whole environment. Karl Berry reported the bug.
5901 * source.c - fix openp to avoid //'s in filenames, which
5902 trigger an Emacs bug causing it to not be able to find files
5903 when running gdb in a window.
5904 * dbxread.c - zap the #if 0 that botches the add-file code.
5905 It seems to work a lot better without all the code commented out.
5907 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
5909 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
5912 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
5914 * Makefile - added a ${CFLAGS} to a couple of entries,
5915 added remote-sa.sparc.c
5916 * added remote.sa-sparc.c, a modification of remote.c
5917 which conducts a dialog directly with the SparcStation prom.
5918 * breakpoint.c, infrun.c, sparcdep.c added
5919 remote_insert_breakpoint(), and remote_remove_breakpoint()
5920 to breakpoint.c instead of directly writing breakpoint instructions.
5921 * sparcdep.c on remote_debugging,there is no need
