6 * elfread.c: Re-enable compilation of register_addr() stub
7 whenever it is not supplied by coredep.c
9 Sat Nov 9 00:40:32 1991 John Gilmore (gnu at cygnus.com)
11 Add tracking of object files (that contain symbols) to gdb.
12 This includes a "struct objfile" that owns symtabs and psymtabs
13 that were read in from that binary file.
15 * symfile.h: Add struct objfile. Add pointer to the objfile
16 into the struct sym_fns.
17 Replace global `symfile' and `symfile_mtime' with
18 `symfile_objfile'. Add global object_files chain.
20 * symfile.c: Move param.h above symtab.h.

28 (allocate_symtab): Takes objfile as new parameter, chains them.
29 Handle INIT_EXTRA_SYMTAB_INFO.

37 Pass objfile. Change callers.
38 (fill_symbuf, SWAP_SYMBOL): Take bfd as arg.
39 (read_dbx_symtab): Just wipe out new symbols, not all, on error.
40 (end_psymtab): Blow away psymtab if empty.

45 * buildsym.c (end_symtab): Pass objfile.
46 (dbx_lookup_type): Handle null typevector.
47 (dbx_alloc_type): Check file number, not sym number, for -1.
48 (find_symbol_in_list): Add for xcoffread.
49 (start_symtab): Default typevector is empty. Keep reusing same
51 (end_symtab): Take objfile argument and pass it to
52 allocate_symtab. Don't make a symtab if no blocks or symbols.
53 Handle empty typevector.
54 (push_context): New function for context stack nesting.
55 (read_type): Mark FIXME where we need to reintroduce type smashing.
57 * buildsym.h (pop_context): Macro, paired with push_context.

66 * dwarfread.c (scan_compilation_units, start_psymtab,
67 process_dies, end_symtab, dwarf_build_psymtabs,
68 read_lexical_block_scope, read_func_scope, read_file_scope): Take
69 and use objfile argument.
70 (psymtab_to_symtab_1, read_ofile_symtab): Don't take or use file
71 descriptor. Use BFD internal functions instead.
72 (end_symtab): Call global allocate_symtab.

77 (struct symtab): Add objfile * and objfile_chain * of symtabs.
78 (struct partial_symtab): Add objfile * and objfile_chain * of
79 psymtabs. Remove symfile_name.

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

462 * configure.in: Handle amigados, amix hosts and targets.
463 * inflow.c: Handle TIOCGLTC_BROKEN for Amiga.
466 * values.c (show_convenience): Use printf_filtered.
467 * main.c (define_command): Check result of lookup_command for
469 (echo_command): Use printf_filtered, and force output out.

474 * utils.c (_initialize_utils): If !ISATTY, don't paginate.
475 * configure.in, tconfig/decstation, xconfig/decstation: Rename
476 dec3100 to decstation.
478 Mon Oct 14 13:37:50 1991 Roland H. Pesch (pesch at cygnus.com)
480 * doc/gdb.texinfo: Catch up to changes recorded here in ChangeLog
481 (nodes Continuing and Stepping; Memory; Targets) clarifications
484 Fri Oct 11 23:27:06 1991 John Gilmore (gnu at cygnus.com)
486 * tm-{irix3,mips,nindy960,pn,symmetry,vx960}.h: Move
487 REGISTER_U_ADDR to corresponding xm- file. Sugg. by Peter Schauer.
489 * symmisc.c (print_partial_symtabs): Add printpsyms debug cmd.
491 * m68k-tdep.c (m68k_push_dummy_frame, m68k_pop_frame): Add
492 generic routines for calling inferior functions.
494 * blockframe.c (inside_main_scope, inside_entry_scope): New.
496 * copying.awk: Filter formfeeds out of copying & warrantee.
497 Make them available as `show copying' and `show warrantee' also.
498 * main.c (print_gnu_advertisement): Advt `show' commands.
500 Thu Oct 10 17:25:47 1991 John Gilmore (gnu at cygnus.com)
502 * mach386-xdep.c: Even when cross-compiling, leave in the
503 core-file reading code.
504 * core.c (get_core_registers): Avoid coredump if no .reg section.
506 Wed Oct 9 17:03:34 1991 John Gilmore (gnu at cygnus.com)
508 * mipsread.c, coffread.c: initialise TYPE_VPTR_FIELDNO to -1.
509 This avoids coredumps under `set print object on' in value_headof
510 (called erroneously by value_from_vtable_info) for `p &struct'
511 or `p *struct'. From Peter Schauer.
513 Mon Oct 7 00:06:52 1991 John Gilmore (gnu at cygnus.com)
515 * Makefile.in: Roll version to 4.1.2.
516 * dbxread.c: Use aout64.h, not a.out.gnu.h. Get external symbol entry
517 size from BFD (but, FIXME, we don't yet read external nlists's and
518 convert them to internal nlists's before handling them -- we still
519 assume they have the same size and alignment.) Use SET_NAMESTRING
521 * exec.c (exec_file_command): Move dead coff-encapsulation code
523 * m88k-tdep.c, m88k-xdep.c: Remove encap test and #inc <a.out.h>.
525 Fri Oct 4 22:30:06 1991 John Gilmore (gnu at cygnus.com)
527 * configure.in, tm-i386v.h, xm-i386v.h: Intel 386 Mach host port.
528 * xm-i386mach.h, mach386-xdep.c, xconfig/i386mach: New files.
530 Fri Oct 4 17:04:31 1991 Per Bothner (bothner at cygnus.com)
532 More patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
533 * mips-xdep.c (store_inferior_registers): Don't try to
534 write the (pseudo) FP.
535 * mipsread.c (parse_partial_symbols): Improved algorithm for
536 setting pst->texthigh.
538 Fri Oct 4 16:47:32 1991 Roland H. Pesch (pesch at cygnus.com)
540 * doc/Makefile: make TEXINPUTS include . everywhere
542 Fri Oct 4 00:35:56 1991 John Gilmore (gnu at cygnus.com)
544 * coffread.c, dbxread.c, symfile.c, symmisc.c, symtab.h: Remove
545 vestiges of typevectors, which were for symsegs and are no longer
546 used. (From a question by Eliot Dresselhaus
547 <dresselh@RFT30.nas.nasa.gov>).
549 Thu Oct 3 09:33:26 1991 John Gilmore (gnu at cygnus.com)
551 * dbxread.c, coffread.c: static-ize functions that were
552 gratuitiously external. (From Fred Fish.)
554 * c-exp.y: sym->class to SYMBOL_CLASS (sym).
556 * dbxread.c (dbx_lookup_type): Keep doubling size of typevector
557 until it is large enough.
559 * dbxread.c (read_type): Handle error case slightly better.
560 Make complaint message not C++-specific.
562 Wed Oct 2 17:21:07 1991 Stu Grossman (grossman at cygnus.com)
564 * infrun.c (wait_for_inferior): Fix step/next so that you only
565 stop at the beginning of a new line. This fixes various problems
566 with for loops, nested if-else's and switch statements.
568 Tue Oct 1 06:33:55 1991 John Gilmore (gnu at cygnus.com)
570 * symtab.c (lookup_symtab_1, lookup_symbol): "fatal" errors
571 between symtabs and psymtabs become ordinary error()s.
573 * dbxread.c (read_dbx_symtab): Relocate end_of_text_addr
574 properly, making "end pc" correct in shared lib psymtabs.
575 (From Guy Harris <guy@auspex.com>.)
577 Mon Sep 30 13:15:31 1991 John Gilmore (gnu at cygnus.com)
579 * dbxread.c: Enable, but soften, const_vol_complaint.
580 (read_dbx_symtab): N_STSYM and N_LCSYM define static vars.
581 Ditto Gould N_NBSTS and N_NBLCS. Also, all types in the psymtab
582 should be file-scope, not global.
583 (read_struct_type): Remove ancient multiple-inheritance warning.
584 (read_range_type): Check base type, complain & patch if undefined.
585 * stack.c (frame_info): Demangle the function name in `info stack'.
588 Sat Sep 28 10:02:33 1991 John Gilmore (gnu at cygnus.com)
590 * eval.c (evaluate_subexp_for_address): Don't use
591 TYPE_POINTER_TYPE directly (it might be zero if this type has
592 never had a pointer created before); use lookup_pointer_type.
593 * symtab.c (lookup_method_type): Arguments were swapped in all
594 callers, so fix it here. I'm amazed this worked at all!
596 Fri Sep 27 18:09:31 1991 John Gilmore (gnu at cygnus.com)
598 * c-exp.y, m2-exp.y: Define more yysymbols that happen to be
599 "bss" rather than "data" symbols, but which still conflict.
602 * coffread.c (coff_symfile_read): Use xmalloc, not malloc.
603 * core.c (core_files_info): Shorten output.
604 * exec.c (exec_files_info): Ditto.
605 (build_section_table): Ignore zero-length sections.
606 * language.c, printcmd.c: Lint.
607 * language.h (get_frame_language): Declare.
608 * saber.suppress: update.
609 * stack.c (find_relative_frame): Remove complex code that was
610 #if 0'd, stick with simple code. Lint.
611 * saber.suppress: Update a bit.

613 * utils.c (parse_escape): Avoid \a due to bdead compilers.
614 * value.h: Declare typedef_print.
616 * valprint.c (val_print, type_print_base): TYPE_CODE_RANGE less
619 * nindy-tdep.c (nindy_frame_chain_valid): Use lookup_misc_func.
620 (Reported by Mark Peek <mark@imagen.com>.)
622 * solib.c (solib_map_sections): Relocate all sections, even
623 though only the text section's size is tracked. Mark ld_text
624 for eventual elimination as we generalize to N sections.
626 * infrun.c (wait_for_inferior): Don't check if the PC is in a
627 call_dummy if we were stopped by a random signal that is being
628 passed to the program. This produced wierd results when calling
629 functions in the inferior and signals (e.g. SIGALRM) were in use.
631 Tue Sep 24 18:05:30 1991 John Gilmore (gnu at cygnus.com)
633 * infrun.c (IN_SIGTRAMP): Not parenthesized properly.
634 Bugfix from Paul Eggert <eggert@twinsun.com>.
635 * tm-ultra3.h (IN_SIGTRAMP): Ditto.
636 * valprint.c (print_floating): Print 9 digits for IEEE floats.

645 Fri Sep 20 16:10:52 1991 John Gilmore (gnu at cygnus.com)
649 * Makefile.in (VERSION): Set to 4.1.
650 * language.c (set_language_command): Print useful help message,
651 and restore the language string after giving help.
652 * valprint.c (typedef_print): Print typedef in C or M2.
653 * symtab.c (list_symbols): Use it.
654 * main.c (main): Avoid any output before (gdb) prompt when -q.
655 * language.c (set_language_command): Handle errors by restoring
656 the language string to its current state (fix from A. Beers).
657 * doc/gdbint.texinfo: Roll in information from README. Rearrange
658 "how to install" and "how to print the doc" stuff so it drops
660 * configure.in: Rename rtpc CPU to romp to match config.sub.
661 * README, WHATS.NEW, TODO: Update for gdb-4.1.
663 Fri Sep 20 17:39:14 1991 Roland H. Pesch (pesch at cygnus.com)
665 * doc/gdb.texinfo: Updates from ChangeLog. set/show write,
666 autoloading shared libs, copyright etc on GDB startup, clean up $_
667 and $__ index refs, set/show listsize and related updates to list
668 cmd. New host/target configs.
670 Fri Sep 20 15:46:00 1991 Roland H. Pesch (pesch at cygnus.com)
672 * doc/Makefile: generate aux version-no file doc/gdbVN.m4
673 from main Makefile.in version definition
674 doc/gdb.texinfo: use version recorded in doc/gdbVN.m4 for current
676 Makefile.in (setup-to-dist): generate doc/gdbVN.m4
678 * doc/gdb.texinfo: merge new language-switching and lang-specific
681 Fri Sep 20 15:00:57 1991 Per Bothner (bothner at cygnus.com)
683 * mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
684 compilers (which may lack stddef.h).
686 Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com)
688 * dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and
689 N_WARNING are the same except for the N_EXT bit, so just use their
690 values alone, rather than OR-ing them with N_EXT.
692 Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com)
694 * mipsread.c (parse_lines): Deal with negative extended line
697 * c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid
698 global symbol conflicts.
700 Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
702 * .gdbinit: Move 'set complaints' to top, so it runs even in
703 case we aren't debugging GDB.
704 * language.c (_initialize_language): Fix type check and range
705 check documentation strings.
706 * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
707 language.c can use it. (Though language.c should really not be
708 handling warnings/errors the way it does, FIXME.)
709 * symtab.c (lookup_primitive_type): const lint.
711 Bugfix from Peter Schauer:
712 * source.c (lines_to_list): Make signed, to avoid comparison
713 going unsigned and complaining that -3 is too high for 21 lines.
714 * stack.c (lines_to_list): Ditto.
716 Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
718 * Makefile.in (HFILES): Add minimon.h.
719 (VERSION): Roll version number to 4.0.95.
720 (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
721 New rules for building distributions. Normal distribution
722 is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
723 one level up from here; it calls make-proto-gdb.dir to build a
724 directory `proto-gdb' which is an image of the release. The old
725 `gdb.tar.Z' rule still works too.
726 * config.sub, configure: Roll in latest from ..
728 Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
730 * doc/gdbint.texinfo: Reorder contents; reorganize new-host,
731 new-target, and new-config chapters; fix minor typos; come closer
732 to usual GNU markup conventions for @file @samp @code @var.
734 Thu Sep 19 17:04:12 1991 Per Bothner (bothner at cygnus.com)
736 Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
737 * mipsread.c (parse_partial_symbols): Enter the name of all
738 structs/unions... into the psymtab so we can access them if the
739 symtab is not read in.
740 * mips-tdep.c: Remove some unneeded #includes.
741 * xconfig/dec3100: Add HAVE_STRSTR.
743 Thu Sep 19 15:14:23 1991 John Gilmore (gnu at cygnus.com)
745 * Makefile.in: Circumvent Sun Make bug on *-exp.tab.o.
746 * c-exp.y, m2-exp.y: Lint.
747 * m2-exp.y: Avoid using yytname[] which is a Bison-ism.
748 * valprint.c (val_print_fields): Check for stub type.
749 * mipsread.c (_initialize_mipsread): Avoid using
750 builtin_type_void at initialize time.
751 (mipscoff_symfile_read): use it now.
753 Wed Sep 18 15:55:51 1991 John Gilmore (gnu at cygnus.com)
755 Merge multiple-language support, and partial Modula-2 support,
756 from Andrew Beers <beers@cs.buffalo.edu>.
758 * i387-tdep.c: New file, consolidates most 80387 support,
759 and eliminates host dependency on double<->extended conversions.
760 * i386-xdep.c, symm-xdep.c: Remove most 387 support.

771 code for saving types of parameters with each function definition.
772 * dbxread.c (define_symbol, function and parameter cases): Ditto.
773 (read_dbx_symtab, case N_DEFD): Ignore.
774 (read_enum_type): Recognize FALSE/TRUE enum as Modula-2 BOOLEAN.
775 (read_range_type): Rename MAX_OF_TYPE to MAX_OF_C_TYPE, etc.
776 #if 0 out its uses, though, since they set a dead value.
777 * coffread.c (end_symtab): Use allocate_symtab.
778 (process_coff_symbol): #if 0'd for functions and params as above.
779 (read_enum_type): Recognize Modula-2 BOOLEAN.
780 * symtab.c (add_param_to_type): #if 0'd function to add a

852 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
854 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
855 entries are enclosed herein. Not all of these changes
856 have been merged into the master GDB sources -- check the
857 ChangeLog above here for the merge log.
859 Mon Jun 3 17:05:45 EDT 1991
861 m2-exp.y Created. Tested outside of GDB for a few days. Proper
862 operators were added, C specific operators and tokens
863 removed. yylex() revamped to some extent. Still things
864 missing from the grammar, such as sets.
865 Tested for two weeks in GDB v3.5.
867 Tue Jun 11 17:23:48 EDT 1991
869 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
870 so they are built-in. Sort of a hack.
872 Fri Jun 14 12:53:51 EDT 1991
874 m2-exp.y Added range checking for numeric constants. Any numeric
875 constant is assumed to be of builtin type INTEGER unless:
876 (1) it is octal or hexadecimal, in which case it is a
877 CARDINAL; (2) it is too big to fit into an INTEGER, in
878 which case it is a CARDINAL.
879 eval.c Added simple range checking for +, -, and * on integers.
880 Doesn't work very well for *, since 6 * 1,000,000,000 =
881 1,705,032,704, which fails the simple test of result >=
882 first_operand, no matter in what order the operands are.
884 Tue Jun 18 14:11:30 EDT 1991
886 Broke the parser into parts, one containing the C grammar and the other
887 containing code to be shared by all of the grammars.
889 The following files no longer exist:
894 The following files were added:
896 c-exp.y (The C grammar)
897 m2-exp.y (The Modula-2 grammar)
898 parser-code.c (Code that is shared by the above grammar)
902 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
903 now necessary to use the Bison compiler compiler, since it
904 will generate function/variable prefixes other than yy.
906 Tue Jun 18 16:47:49 EDT 1991
908 symtab.[ch] Added the external variable working_lang, than holds the
909 value of the current working language.
910 Added the ennumerated type language_mode, with the values
911 language_auto and language_manual, the former meaning that
912 GDB sets working_lang as needed, and the latter meaning
913 that the value of working_lang is totally under user
915 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
916 REAL, BOOLEAN and CHAR. Also added the type codes
917 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
918 utils.c Added set_language_command and show_language_command to
919 implement the GDB support commands "set language" and
921 expression.h A number of identifiers were added to the type exp_opcode
922 to facilitate Modula-2 builtin functions, integer
923 division, and array indexing.
925 Wed Jun 19 13:25:58 EDT 1991
927 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
928 if the language specified by working_lang requires the use
929 of strict typing of expressions. Eventually, even this
930 will be able to be changed by the user.
931 Added the macro RANGE_CHECK, which evaluates to non-zero
932 if the language specified by working_lang requires the
933 checking of a value against the domain of its type.
934 Eventually, even this will be able to be changed by the
936 language.[ch] Predicates involving types (simple_type, ordered_type,
937 same_type, integral_type, numeric_type, character_type,
938 boolean_type, float_type) are added. These predicates are
939 based on the current value of working_lang, and are handy
942 Wed Jun 19 15:39:34 EDT 1991
944 eval.c Added the function type_array_rank which computes the rank
946 valarith.c Added the funtion value_bool, which when given a integer
947 value.h value (ie. struct value *) as an argument, it returns a
948 boolean value (ie. struct value *) true if that integer
949 is non-zero, and a boolean value false otherwise.
950 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
951 will print out properly.
953 Wed Jun 19 16:36:34 EDT 1991
955 valops.c Added the function value_capitalize, which returns it
956 value.h argument capitalized if its argument is a lowercase
957 letter, or the argument unchanged if its argument is not a
959 valarith.c Added the function range_check_p, which returns non-zero
960 value.h if its value argument is between the integral bounds upper
962 Added the function range_check_enum_p, which makes sure
963 that its value argument is a valid member of the domain of
965 Added the function range_check_range_p, which makes sure
966 its value argument lies between the upper and lower bounds
967 of its type argument, which must be a ranged type.
968 Added the function check_array_index, which range and type
969 checks an index of an array.
970 Added the function value_multi_subscript, which computes
971 array[idx1,idx2...idxN], given a value array and an array
972 of values representing indicies.
973 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
974 unpack_long to work with TYPE_CODE_BOOL and
977 Wed Jun 19 18:04:08 EDT 1991
979 symtab.c Stored pervasive types in a structure and make
980 lookup_pervasive_type() a lookup function that was based
981 on working_lang. If lookup_pervasive_type() returned
982 non-zero, then that value was returned (a fix, since
983 before it simply wouldn't return the pervasive type.)
984 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
985 non-zero if the language specified by working_lang means
986 "conversion" when it says "cast".
987 valops.c Added the function value_real_cast(), which performs a
988 value.h *cast*, not a *conversion*, which is what value_cast()
989 does when it can. In particular,
990 value_cast(<float_type>,4) = 4.0, while
991 value_real_cast(<float_type>,4) = some mess.
992 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
993 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
994 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
995 and MIN on integral types. *NOTE*: These are currently
996 hardcoded to work only if there are 8 bits per storage
998 eval.c Made logical functions call value_bool to return a
999 properly typed boolean value, based on working_lang.
1001 Thu Jun 20 11:55:27 EDT 1991
1003 valprint.c Types now print out in a Modula-2 fashion. This works for
1004 the cases when the type is printed out step-by-step, that
1005 is, it doesn't work when the name of a structured type
1006 (which includes the keyword "struct", etc.) is simply
1008 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
1009 since type specifications in C and Modula-2 are very
1010 different. The C printing of a type is very recursive,
1011 whereas in Modula-2 it is generally very simple. C has
1012 type prefixes and suffixes, which have no real analogue in
1013 Modula-2. Maybe type_print() should call a language
1014 specific type printer. This is also advantageous if we
1015 compile GDB to exclude some of the languages. We'll just
1016 leave those functions out.
1018 Thu Jun 20 16:57:10 EDT 1991
1020 dbxread.c When reading the complete symbol table in (via
1021 psymtab_to_symtab()), the number and types of function
1022 arguments are added to a function type. define_symbol()
1023 calls add_param_to_type() to accomplish this.
1024 Assumption: when we come across a function definition
1025 (N_FUN symbol with an 'f' or 'F' in the name), its
1026 arguments will appear before another function definition.
1027 When a function is found, a pointer to its type is placed
1028 in the global in_function_type. Changes that
1029 add_param_to_type() makes are to this global.
1030 valprint.c The type of a function now includes (for Modula-2) the
1031 types of its parameters.
1032 eval.c Type checking and a check for the proper number of
1033 arguments is now done for function calls. Not sure of the
1034 impact this has on C++ member function yet.
1036 Thu Jun 20 19:58:48 EDT 1991
1038 valprint.c Rewrote the type printer. Broke it into two language
1039 specific parts, adding the functions type_print_m2() and
1041 An unfortunate consequence is this: if you debugging a C
1042 program in Modula-2 mode (why?), info types does not work
1043 well with regular expressions, since the types are printed
1044 out in Modula-2 terminology, but stored in C terminology.
1045 language.[ch] Added the functions new_type_last(), type_keyword(), and
1046 type_sep() to aid in the printing of typedefs.
1047 symtab.c Made the printing of typedefs as language independent as
1048 possible through calls to new_type_last(), type_keyword(),
1051 Fri Jun 21 11:50:26 EDT 1991
1053 dbxread.c Check all incoming ennumerated types. If it looks like
1054 Modula-2's BOOLEAN type, then change the type_code of the
1055 type to TYPE_CODE_BOOL so we can process it as a boolean
1057 valprint.c Replaced some of the 0x%x with calls to sprintf and
1058 hexformat() in val_print().
1059 language.[ch] Added the function hex_to_string(), which converts its
1060 integral argument to a hexadecimal number (format is
1061 language based) and returns the result as a string.
1063 Mon Jun 24 12:25:07 EDT 1991
1065 valprint.c Some functions call type_print_1() directly, instead of
1066 value.h using type_print(), so they can specify where (column) to
1067 print things. Since type_print() takes care of language
1068 dependence, that needs to be called first. Added a
1069 parameter depth to type_print() (so it is now like
1070 type_print_1). Changed type_print to type_print_at, and
1071 made type_print a macro that passes a depth argument of
1073 symmisc.c Changed all calls to type_print_1 to calls to
1075 Makefile.dist Made it possible to build GDB for a specific set of
1076 depend languages. Do this by passing a definition for the macro
1077 LANGS to make. LANGS should be a string containing a
1078 space-separated list of language names (ie. LANGS="c m2").
1079 The default is to build all languages. Note that grammar
1080 files must follow the naming convention of <lang>-exp.y.
1081 gdb.lang This holds the current value of the LANGS macro. It is
1082 examined every time make is called, and is updated if
1084 eval.c Added #ifdef _LANG_<lang> to these files.
1085 expread.c Still need to add them to dbxread.c and coffread.c.
1093 Mon Jun 24 16:33:11 EDT 1991
1095 language.[ch] Added the functions hexformat_pre() and
1096 hex_to_string_pre(), which take a prefix argument to
1097 include in the format string. Thus, hexformat_pre("08") will
1098 return "0x08x" (if the working language is language_c).
1099 Made hexformat() and hex_to_string() calls to the above
1100 with "" as the prefix argument.
1102 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
1103 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
1104 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
1105 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
1106 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
1107 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
1108 valprint.c, vax-pinsn.c
1110 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
1111 calls to hexformat() and hex_to_string(). Format strings without
1112 the leading "0x" were ignored.
1114 depend Updated to take the above into account.
1117 Tue Jun 25 15:27:18 EDT 1991
1119 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
1120 and type_check_t to keep track of the current state of
1121 range and type checking.
1122 main.c Added the variables range_mode, range_check, type_mode,
1123 and type_check to record the current state of range and
1124 type checking. Added initialization code to main().
1125 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
1126 the above variables.
1129 Tue Jun 25 17:57:08 EDT 1991
1131 dbxread.c process_one_symbol() updates the variable (enum language)
1132 source_lang based on the extension of the filename
1133 contained in the N_SO sybmol that started this symtab.
1134 When end_symtab() is called, the value of source_lang is
1135 put into the language field.
1136 stack.c select_frame() sets working_lang (and possibly type_check
1137 and range_check) to the language field of the symtab
1138 associated with the frame that is selected if working_mode
1139 is language_auto. If working_mode is language_manual, a
1140 warning is printed and working_lang is not set.
1141 language.c Added the function set_type_range(), which sets the value of
1142 type_check and range_check (if their modes call for
1143 automatic setting) based on the current value of
1144 working_lang. A non-zero argument will cause the current
1145 settings to be output.
1148 Wed Jun 26 14:51:40 EDT 1991
1150 eval.c Added range checks on assignment.
1151 m2-exp.y Added the grammar for sets to the language. Currently,
1152 these do not do anything except print an error message.
1154 Wed Jun 26 17:01:04 EDT 1991
1156 m2-exp.y Added the ability for parse_number() to parse negative
1157 numbers. A global flag is set upon encountering a unary
1158 minus. This was done to make, for example, 1 parse as a
1159 CARDINAL, and not as an integer, per Wirth's examples in
1160 Programming in Modula-2 ed.4.
1161 valprint.c Added support for "set radix 2" by then setting
1162 output_format to 't'.
1163 eval.c Implemented range checking on subrange types. Added calls
1164 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
1165 Implemented MIN and MAX for ennumerated types. The
1166 minimum value of an ennumerated type is defined by Wirth
1167 as the first identifier, and the maximum as the last.
1168 m2-exp.y Made octal numbers ending with "B" be characters and those
1169 ending with "C" be numbers, per Wirth's book. (p. 34)
1171 Thu Jun 27 14:11:52 EDT 1991
1173 stack.c select_frame() now only sets working_lang, it does not
1174 notify the user. If working_mode is language_manual, then
1175 a warning is issued once.
1176 main.c At the end of each call to execute_command(), working_lang
1177 is checked against the local static (enum language)
1178 current. If they differ and working_mode is
1179 language_auto, the new settings of language, type and
1180 range checking are printed out.
1181 stack.c Modified frame_info() to include the language of the
1182 current frame in the output of "info frame".
1183 language.[ch] Added the function language_str() which returns the name
1184 of the current language.
1186 Fri Jun 28 15:33:14 EDT 1991
1188 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
1189 the language. INCL and DECL currently cause an error,
1190 since sets are not implemented yet. INC and DEC are
1191 implemented as PREINCREMENT/PREDECREMENT with one
1192 argument, and as ASSIGN_MODIFY with two arguments.
1193 eval.c Added type checking to the above cases.
1194 value.h Added not_lval_constant to the lval_type ennumerated type.
1195 not_lval_constant means that the value is a constant
1196 value; that is 3 or 'a' or TRUE, not as in a constant
1197 identifier. This is used to help coerce numbers such as 3
1198 to either signed or unsigned numbers.
1199 valops.c Added the function value_coerce_constants() which coerces
1200 constant integers as following: if one is a constant and
1201 the other is not, the constant's type is set to the type
1202 of the other argument. If both are constants and one is
1203 signed, the other is converted to a signed constant.
1205 Sat Jun 29 17:26:29 EDT 1991
1207 valarith.c Added a better range checker. It now checks range
1208 (successfully) on integral operations [+-] (signed and
1209 unsigned) for any C sized type. Still does not work well
1210 for multiplication.)
1211 int_in_size() returns an integer that is coerced to fit into
1212 specified number of bytes.
1214 Mon Jul 1 13:04:14 EDT 1991
1216 language.[ch] Added the function binop_result_type(), which returns the
1217 builtin (struct type *) type that would be the result of a
1218 binop on the two values V1 and V2.
1220 Wed Jul 3 19:22:53 EDT 1991
1222 source.c Extended source_info() to include the source language in
1223 the output from "info source".
1225 Fri Jul 5 13:48:52 EDT 1991
1227 utils.c Moved the support functions for the GDB set/show commands
1228 dealing with language into language.c.
1229 language.c Added the function language_info(), which displays info
1230 about the current working language, type and range check
1231 settings. Called via the GDB command "info language".
1232 Added an initialization routine _initialize_language(),
1233 that sets defaults for the language, type and range
1234 variables and sets up the new GDB commands.
1235 main.c Language setup moved to language.c.
1238 Mon Jul 8 10:10:22 EDT 1991
1240 valarith.c Debugged the range checker for arithmetic. Still does not
1241 work for multiplication very well.
1243 Mon Jul 8 12:40:37 EDT 1991
1245 language.[ch] Added the function value_true() which returns non-zero if
1246 its argument represents a boolean true value.
1247 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
1248 check the truth of an expression.
1250 Thu Jul 11 12:51:34 EDT 1991
1252 language.[ch] Added the predicate structured_type(), which returns
1253 non-zero if the argument is a structured type.
1254 Added the predicate pointer_type(), which returns non-zero
1255 if the argument is a pointer type.
1256 eval.c Added the ability to do addition and substraction on
1257 pointers and integers. This case simply bypasses the
1260 Thu Jul 11 14:41:42 EDT 1991
1263 Added the symbol N_DEFD (0x4a) which is a definition
1264 module dependency that is used by the GNU Modula-2
1265 compiler and the linker. It is not important to GDB,
1266 except that [dbx|coff|mips]read.c should ignore these
1269 Fri Jul 12 16:07:00 EDT 1991
1271 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
1272 0 in val_print(). Also added statements to the else part
1273 to coerce type (argument to val_print) to a pointer type
1274 if it is an "array of unspecified length".
1275 valops.c Added the function value_m2_string(), which returns a
1276 (value) value which is a constant string, whose type is
1277 (ARRAY [0..n] OF CHAR). The length field of the type
1278 structure is set to zero, so it will be interpreted as an
1279 "array of unspecified length".
1280 stack.c Moved the language/frame mismatch check to
1281 main.c:execute_command().
1282 main.c The working language is recorded each time
1283 execute_command() is executed. If working lang has
1284 changed during its execution, then the new
1285 language/type/range info is printed out for the user. If
1286 the working language does not match the language of the
1287 frame, a warning is issued.
1289 Sat Jul 13 16:16:39 EDT 1991
1291 eval.c Moved all the type-checking stuff for operators to
1292 language.[ch] language.c. This is so we can keep language-specific
1293 stuff (like for what type operators are defined) in
1295 language.[ch] Added the function binop_type_check(), which checks to see
1296 if its two (value) arguments are type-compatible with its
1297 opcode argument. The opcode should represent an operation
1298 involving an operator. Also added the macro function
1299 unop_type_check, which calls binop_type_check with a
1300 NULL second argument.
1301 expprint.c Added Modula-2 operators to the op_print_tab, so info
1302 expression.h break works correctly. Also added "op_string", which
1303 returns the string corresponding to the (enum exp_opcode)
1304 opcode that is its argument.
1307 Sat Jul 13 18:26:18 EDT 1991
1309 coffread.c Added code to record the type of function arguments with
1310 each paricular function. Code is very similar to that
1312 dbxread.c Moved add_param_to_type() to symtab.c
1313 symtab.[ch] Added function add_param_to_type() from dbxread.c
1315 *** NOTE: The above additions have not been tested.
1317 Mon Jul 15 12:50:47 EDT 1991
1319 langauge.[ch] Added the functions type_error and range_error, which work
1320 like error() except if the type/range mode is set to
1321 *_mode_warn, then they do not do a return_to_top_level(),
1322 but merely print a warning.
1323 Also changed [set|show]_[type|range]_command() to support
1324 the new "warn" feature.
1326 Thu Jul 18 17:50:54 EDT 1991
1328 mipsread.c Added code to record the type of function arguments with
1329 each particular function. Code is very similar to that
1332 *** NOTE: The above additions have not been tested.
1334 Fri Jul 19 11:19:10 EDT 1991
1336 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
1337 UMIN_OF_SIZE, which when given a size of a numeric type,
1338 return the maximum and minimum value it can hold. UMAX...
1339 and UMIN... return the result for unsigned types.
1340 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
1341 struct types. They call above macros.
1342 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
1343 avoid a name conlict with the above.
1344 c-exp.y Added range checking on numeric constants in
1345 parse_number() for completeness.
1346 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
1347 return 0 if working_lang is not language_c.
1349 Thu Aug 8 14:17:22 EDT 1991
1353 breakpoint.c Documentation strings of some commands changed to
1354 eliminate the references to the C language where
1357 Tue Aug 13 15:48:03 EDT 1991
1359 m2-exp.y Added qualified identifiers to the grammar. The semantics
1360 are slightly different from those of the GDB operator ::
1362 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
1363 type_exp, where type_exp is any valid type expression.
1365 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
1366 printcmd.c Modified ptype_command() so it actually parses the input
1367 (necessary for type expressions with scope qualifiers).
1368 Added the function ptype_eval() which expects an
1369 expression composed of one OP_TYPE element.
1370 *.[ch] Replaced all occurences of parse_c_expression with
1372 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
1374 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
1376 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
1378 Small fixes from Peter Schauer:
1380 * infrun.c (child_attach): Lint.
1381 * solib.c (find_solib): Handle shared libs version 2.
1383 Small fixes from David Wood:
1385 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
1389 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
1390 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
1392 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
1393 chars_per_line is at maximum (user typed `set width 0'). Fix
1394 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
1396 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
1398 * coredep.c: include ptrace.h where necessary.
1399 * mipsread.c(parse_lines): fix unsigned char problem that was
1400 messing up line numbers on SGI's and possibly other MIPS based
1402 * infrun.c (child_create_inferior): use better test to check
1403 return val from setpgrp().
1404 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
1405 for sgi/irix support.
1407 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
1409 * mipsread.c (parse_symbol): Put non-static procedures
1410 in the global block.
1412 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
1414 Patch together `text_start' and `text_end' for 29K port.
1416 * exec.c (exec_command): If NEED_TEXT_START_END, define the
1417 variables and set them based on the exec file.
1418 * am29k-tdep.c: declare text_start.
1419 * valops.c (call_function_by_hand): declare text_end.
1421 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
1422 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
1423 because machines that do this will also have to know to
1424 set NEED_TEXT_START_END. Besides, it was a redundant way to
1426 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
1427 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
1428 NEED_TEXT_START_END.
1430 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
1432 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
1434 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
1435 Pass MUNCH_DEFINE to munch whenever we run it.
1436 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
1437 format string; use 0x%x instead.
1438 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
1439 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
1440 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
1441 * inflow.c: Handle `short' process group IDs.
1442 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
1443 and check for ptrace errors.
1444 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
1445 (coff_symfile_init): Initialize text_bfd_scnum.
1446 (read_coff_symtab): Use it to find the text [and absolute?] sections.
1447 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
1448 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
1449 Merge target arm case with other "easy" cases. Add target
1450 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
1451 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
1453 * minimon.h, remote-adapt.c, remote-mm.c: Add.
1454 * munch: Cope with RT/PC putting fns in data segment.
1455 Restore ability to override `nm' by specifying MUNCH_NM.
1456 * xconfig/rtbsd, xconfig/ultra3: New host systems.
1457 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
1458 and remote-adapt. Remove encapsulated coff #define's (the
1459 support should go in BFD, and gdb shouldn't know or care).
1460 * tconfig/a29k-kern: Same, but for remote kernel debugging.
1461 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
1462 * tm-29k.h: Update BADMAG (though it should go away).
1463 Allow the register definitions to be overridden in another
1464 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
1465 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
1466 DUMMY_SAVE_GR96, for handling kernel calling conventions
1467 that use GR64+ rather than GR96+.
1468 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
1469 remote debugging of Ultra3 kernel. Includes tm-29k.h and
1470 overrides various things.
1472 * remote-mm.c (mm_attach, mm_wait): Handle attach like
1473 child_attach does, making a clean stop in the newly attached
1475 * remote-eb.c: Lint.
1477 * coffread.c: Make coffread independent of any particular
1478 variant of COFF. Avoid #include-ing any particular one except
1479 internalcoff.h. BFD now passes key values for symbol reading
1480 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
1481 and the symbol masks and shifts); use them.
1482 Remove obsolete end_of_text_addr.
1484 * exec.c: Remove unused include files.
1486 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1488 * Makefile.in (documentation targets): Pass $(M4).
1489 Bugfix from eggert@twinsun.com (Paul Eggert).
1491 * stack.c (down_silently_command): Check for stack existence.
1493 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1495 * Makefile.in (VERSION): Update to 4.0.3.
1497 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1499 * core.c (core_file_command): Print frame at coredump with
1500 its level number, by calling print_stack_frame.
1501 * frame.h: Add selected_frame_level, print_stack_frame.
1502 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
1503 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
1504 Change print_sel_frame and print_selected_frame callers to
1507 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
1508 * symfile.c (free_named_symtabs): Ditto.
1509 * main.c (main): wrap_here needs an arg.
1510 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
1511 (solib_add): Avoid noise.
1512 (solib_create_inferior_hook): Lint.
1513 (sharedlibrary_command): Move dont_repeat to here.
1514 * utils.c (error): Call wrap_here to force buffered output.
1516 Small patches from Peter Schauer:
1518 * coffread.c (start_symtab): Free any existing line_vector before
1520 (read_coff_symtab): Ditto for type_vector.
1522 * source.c (lines_to_list): New variable, replacing function.
1523 (all uses): Use as variable.
1524 (_initialize_source): Add 'set listsize' and 'show listsize'.
1525 * utils.c (lines_to_list): Remove function.
1526 * stack.c (print_frame_info): Use as variable.
1527 * defs.h (lines_to_list): Remove declaration.
1529 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1531 * breakpoint.c (insert_breakpoints): Restore warning about
1532 the program might be running in another process, but only for
1533 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
1534 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
1536 * utils.c (error): if error_pre_print is set, print the string
1538 * main.c (main, print_gnu_advertisement, print_gdb_version):
1539 Reformat legalese so it always prints, but acts as an "I'm here"
1540 message while symbols are being read. If any errors occur,
1541 print a few newlines to set off the message and start it at the
1542 left margin. Remove mention of "help" command, and don't yak
1543 about symbol reading.
1544 (catch_errors): Error string is now printed first in case of
1546 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
1547 suggest the "help" command.
1549 * Makefile.in (VERSION): Set to 4.0.2.
1551 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
1553 * .gdbinit: Remove useless "rr" command. Set complaints
1554 to 1 for people debugging gdb.
1556 * breakpoint.c, remote-vx.c: Reword strings printed by
1557 catch_errors callers.
1559 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
1561 * WHATS.NEW: "history write -> history save". Doc "write on/off".
1562 (Fix from kenc@viewlogic.com.)
1564 Fix some infrastructure to be able to cope with host and target
1565 machines with different sized basic types (ints, ptrs, etc).
1566 (Idea from pierre@la.tce.com (Pierre Willard).)
1568 * values.c (value_from_longest): Rename from value_from_long.
1569 Handle pointer types as well as integers, so that targets with
1570 different pointer sizes from the host can be accomodated.
1571 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
1572 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
1573 uses of value_from_long to value_from_longest.
1574 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
1575 the correct pointer type to value_from_long{est}.
1577 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
1579 * remote-vx.c: Remove obsolete code for calling functions via
1580 vxworks kludge interface (it referenced value_from_long).
1582 * valops.c (value_string): Find malloc with lookup_misc_func, not
1585 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1587 Make writing to files work properly. (Fixes to BFD are also needed.)
1589 * core.c (core_open): Open file ourselves, read or r/w, depending on
1590 write_files. Use bfd_fdopenr.
1591 * gdbcore.h (write_files): New variable.
1592 * exec.c (write_files): Define variable, add set&show for it.
1593 (exec_file_command): Use write_files to open for read or r/write.
1595 Make shared library reading happen automatically. These changes
1596 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
1598 * inferior.h (stop_soon_quietly): Add to exported variables.
1599 * infrun.c (child_create_inferior): call solib hook, if defined.
1600 (child_attach): call solib hook, if defined.
1601 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
1602 (find_solib): Use lookup_misc_func rather than hand-rolled.
1603 (symbol_add_stub): New stub for catch_errors.
1604 (solib_add): Avoid output if !from_tty. Catch errors rather
1605 than just calling symbol_file_add and bombing.
1606 (solib_create_inferior_hook): Interface with the target process
1607 to let it read and alloc shared libs, then figure out what it did.
1609 * core.c (validate_files): Fix typo, soften warning.
1610 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
1612 * utils.c (fputs_demangled): Avoid duplicate printing if
1613 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
1615 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
1616 (Fix from pierre@la.tce.com (Pierre Willard).)
1618 * main.c (catch_errors): Change argument to a char * from an int,
1619 since a char * can point to a struct full of glop, but an int
1620 is not guaranteed to be able to hold a pointer.
1621 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
1622 breakpoint_re_set_one, breakpoint_re_set): Adapt.
1623 * core.c (core_open, solib_add_stub): Adapt.
1624 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
1626 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1628 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
1629 by adding .NOEXPORT target.
1631 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1635 * Makefile.in (VERSION): Roll to 4.0.
1636 (gdb.tar.Z): Make refcard.ps as well, for shipment.
1638 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1640 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
1643 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
1646 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
1648 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
1649 reflect above name change
1651 * WHATS.NEW: correct pointer to refcard.
1653 * doc/gdb.texinfo: update New Features, Installing
1655 * doc/gdbint.texinfo: add short description of configure +template
1657 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1659 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
1661 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
1663 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
1664 tar file, add dependencies for referenced doc files.
1666 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
1668 * coffread.c, symfile.c, stack.c: saberized.
1670 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1672 * doc/refcard.tex: permuted Essential Commands sec
1674 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
1676 set/show symbol-reloading
1677 default set complaints 0
1679 RET-repeat disabled after prompted long displays
1680 processID (attach) interpretation of 2nd GDB cmdline arg
1682 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
1684 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
1685 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
1686 breakpoint.c, main.c: lint.
1688 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1690 Install new configuration scheme for GDB and friends.
1692 * config.sub: Translate ordinary names to three-part names.
1693 * configure: Use three-part names internally.
1694 * configure.in: Translate three-part names to filenames.
1696 * README, WHATS.NEW: Update for gdb-4.0.
1697 * Makefile.in: Roll VERSION to 3.99.
1699 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
1701 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
1702 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
1703 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
1704 to single structures rather than arrays; when passing
1705 their address, use &. This avoids trouble with bdead compilers.
1706 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
1707 instead. This avoids portability headaches.
1708 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
1710 * source.c (open_source_file): Avoid ANSI const bdeath by
1711 skipping declaration and then casting result value.
1712 * tm-hp300bsd.h: Clarify comment.
1713 * utils.c (strstr): Result is const char *; ANSI bdeath.
1714 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
1715 since system include file defines it differently from "defs.h",
1716 though the two are equivalent for our purposes.
1717 * tconfig/hp300bsd: Add m68k-tdep.o.
1719 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1721 * tconfig/sun*4: Remove warnings about system assembler.
1723 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1725 * mcheck.c: Avoid warning about undeclared abort fn.
1726 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
1727 it causes recursive calls to error() when used in cleanups.
1728 To do so requires that we make it a function, so we do.
1729 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
1730 * utils.c (do_cleanups): Remove the current cleanup from the
1731 chain *before* calling it, in case error() is called from it.
1732 The result won't be pretty, but won't be an infinite loop either.
1734 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
1736 * dbxread.c (read_struct_type): Grok anon structs for C++.
1737 (vb_name, vptr_name): Null terminate these strings.
1739 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1741 Minor bug fixes from BSD Net2 gdb:
1743 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
1744 returns 0, there is no previous frame.
1745 * breakpoint.c (commands_command): If !from_tty, don't call
1746 input_from_terminal_p().
1747 * dbxread.c (record_misc_function): Speed up slightly.
1748 (compare_psymbols): Ditto.
1749 * infcmd.c (do_registers_info): Take a second argument to
1750 determine whether to print float registers. "info registers"
1751 does not do so anymore. "info all-registers" does, now.
1752 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
1754 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
1755 * inflow.c (initialize_inflow): Set tflags_ours correctly.
1759 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
1760 executing_breakpoint_commands if we are interrupted by error.
1761 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
1762 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
1763 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
1764 catch_errors() so we can setup the frame regardless of whether
1765 the shared libs work.
1766 * ieee-float.c (double_to_ieee_extended): Get exponent from
1767 right place in little-endian systems. From John Carey.
1769 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1771 * main.c: Remove unused terminating_signals and catch_termination().
1772 (long_options): Terminate with a zero element.
1773 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
1774 (gdb_readline): Make call-compatible with readline.
1775 (init_signals): Improve comments re vfork vs. signal.
1777 * utils.c (prompt_for_continue): Use new gdb_readline().
1778 If we prompt for continuation, we don't let CR repeat the previous
1779 command, once we get back to a prompt. It's too easy to keep
1780 hitting CR, expecting "--more--" prompts, and have some long
1781 command start repeating on you.
1783 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1785 * blockframe.c (frameless_look_for_prologue): Speed up by
1786 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
1787 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
1788 Define two variants, one faster.
1789 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
1790 and return zero, rather than giving an error.
1791 (setup_arbitrary_frame): Initialize the PC in the new frame.
1792 (skip_prologue): Add a second arg saying whether we're just
1793 checking for a frameless function or not.
1795 * core.c (core_open, core_close, core_xfer_memory): Move
1796 section table pointers and bfd* into the target_ops.
1797 (core_open): Allow errors in shared lib reading, etc.
1798 (core_files_info): Describe shared library sections.
1800 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
1801 exec_files_info, set_section_command): Move section table
1802 pointers and bfd* into the target_ops.
1803 (add_to_section_table): Add BFD to section table.
1805 * target.c (target_xfer_memory, target_info): Pass target to
1806 xfer_memory and target_info functions.
1809 * gdbcore.h: Move struct section_table.
1810 * target.h: New home of struct section_table.
1812 * solib.c (solib_add): New argument is the target_ops whose
1813 section list is to be added to, if any. Reallocate the
1814 sections in that target to add any that come from shared libs.
1815 (throughout) so_sections renamed to sections.
1816 (solib_xfer_memory): Deleted.
1817 * tm-sunos.h (SOLIB_ADD): Add target argument.
1818 (SOLIB_XFER_MEMORY): Delete.
1820 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1821 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
1822 from target_ops. It's the same on all targets. Add two section
1823 pointers to target_ops.
1825 * stack.c (find_relative_frame): Dump ancient algorithm for
1826 "down", just use handy "next" pointers.
1827 (frame_command): Don't error if there is no stack; let user
1830 * inflow.c (new_tty_prefork, new_tty): New prefork routine
1831 modifies static state in the parent process; new_tty itself
1832 runs in the child and modifies the child's file descriptors
1833 to match the saved static state.
1834 * infrun.c (child_create_inferior): Call new_tty_prefork,
1837 * infptrace.c (child_xfer_memory): Add ignored target arg.
1838 * remote-eb.c (eb_xfer_inferior_memory): ''
1839 * remote-nindy.c (nindy_xfer_inferior_memory): ''
1840 * remote-vx.c (vx_xfer_memory): ''
1841 * remote.c (remote_xfer_memory): ''. Rename from
1842 remote_xfer_inferior_memory.
1844 * main.c (main): Only try to attach "corefile" argument if
1845 it starts with a digit.
1847 * symfile.c (symbol_reloading): New "set/show" variable.
1848 (symbol_file_add): Shorten message about symbol reading.
1849 (add_symbol_file_command): Merge with add_syms_addr_command,
1850 since this should work on all targets now.
1851 (stop_whining): Default to zero, to shut up complaints
1852 about bad symbol tables on many systems.
1853 (free_named_symtabs): Just exit unless symbol_reloading.
1855 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
1856 and add comment explaining shared library screw.
1858 * source.c: #if defined => #ifdef.
1860 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1862 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
1864 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1866 * doc/rdl-apps.texinfo: provide default readline-appendix finder
1867 (doc/Makefile knows how to make one for local config)
1869 * Makefile.in: use doc/Makefile for doc targets
1871 * doc/Makefile: GDB documentation now has its own Makefile
1872 doc/refcard.tex: renamed from "gdbrc.tex"
1873 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
1874 doc/gdbint.texinfo: add markup in "Cleanups" chapter
1877 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1879 * values.c (baseclass_addr): When reading target memory, use the
1880 length of the basetype, not the upper type. We've only malloc'd
1881 enough space for the basetype, leading to errors in free().
1883 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
1884 ends up as a function specially, since we know the actual type of
1885 the pointed-to address. This (somewhat) fixes display of
1886 expressions that include misc_function_vector names. Try `cond 1
1887 !strcmp("a","b")' then `i b'.
1889 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
1890 The child can be proceeded from inside wait_for_inferior in
1891 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
1892 getting skipped in that case.
1894 * expprint.c (print_subexp): Use filtered output, since the
1895 subroutines we call use it, otherwise the output is horribly
1896 mangled, since output of wrappable stuff comes out late.
1898 * Makefile.in: Bump VERSION to 3.98.1
1900 * infrun.c (child_create_process): Use execlp to find the
1901 shell to exec our target program. This requires some fiddling
1902 with `environ' since there is no execlpe().
1904 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1906 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
1907 Minor rearrangement of refcard permits two new make targets--
1908 gdbrc.dvi DVI output for refcard, using CM fonts
1909 gdbrc.ps PostScript refcard, using PS fonts
1911 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1915 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
1916 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
1918 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1920 * doc/gdb.texinfo: last changes for release.
1921 Minor typo and formatting fixes; incorporated most fixes remaining from
1922 filed mail commenting on earlier drafts.
1924 Added warnings: pipes don't work in run command;
1925 conditions are converse of assertions;
1926 step over fn without debug info goes to next fn;
1927 vars may have "wrong" values near fn entrance, exit
1929 Added example from Kingston on printing repeated nonadjacent values
1931 Added explicit mention that in Emacs gdb mode C-c and C-z are like
1932 shell mode for signals
1934 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
1935 doesn't sound so much like its parent "Stopping and Continuing"; also
1936 moved entries on continue to top of section, so they don't get lost.
1938 Improved installation directions in appendix, added manual formatting
1941 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1943 * configure.in: Remove xm.h and tm.h even if we aren't linking
1944 new ones, so "./configure sun4; ./configure none" does the right
1945 thing. Assume that alldeps.mak and depend are already built in
1946 srcdir, and avoid running "make" (particularly "make depend",
1947 which involves "gcc") from inside configure. Build Makefile
1948 directly rather than building Makefile.conf first.
1949 * configure: Regenerate with above changes.
1950 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
1951 to 3.98. Revise gdb.tar.Z procedure to produce a file
1952 called gdb-$(VERSION).tar.Z but which unpacks into a
1953 directory called "gdb". Move non-source files out of
1954 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
1955 (depend): Don't try to do "gcc expread.y".
1956 (expread.o): Update dependencies by hand.
1958 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1961 Fixed a variety of small typos that prevented info from formatting
1962 cleanly; altered too-long heading for GPL Appendix, as discussed
1963 w/RMS; Changed date on cover to July 91.
1965 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1968 (1) Applied some fixes due to comments from Larry Breed (easier ones
1969 through chapsec 5.2)
1970 (2) Eliminated use of @footnote---had my doubts about it anyways, and
1971 it's broken in latest texinfo
1972 (3) Introduced *some* use of [] for optional arguments, where
1973 explanation is not simpler by listing cmd w arg and cmd w/out arg
1974 separately. Still not using @deffn.
1975 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
1976 couple of headings are too long. Need patches to texinfo or revision
1979 * Partial update to README (which still needs work for this
1980 release!): (1) use of configure corrected for new script,
1981 (2) "make gdb.dvi" and "make gdb.info" mentioned.
1983 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
1985 * symtab.c (lookup_symbol): Don't complain right off about
1986 no debug symbols; use the misc function vector first.
1987 (list_symbols): Use misc function vector to find symbols
1988 that don't have debug info, and print them.
1989 (find_pc_symtab): Temporarily avoid fatal() when psymtab
1990 PC range doesn't match symtab PC range, as it does on the
1991 MIPS because our symtab reading isn't perfect.
1993 * dbxread.c (dbx_symfile_read): Make warning about
1994 "no debug symbols" slightly nicer.
1996 * source.c (select_source_symtab): If "main" symbol exists,
1997 but decode_line_spec can't find line info, don't just return
1998 a zero; try other source symtabs or give an error.
2000 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
2001 their low addresses first, then rip through fixing high addrs.
2003 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
2004 <runene@ifi.uio.no>.
2005 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
2007 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2009 * Minor, mostly mechanical, cleanup of doc subdir for clean
2010 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
2011 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
2013 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
2015 Mostly MIPS and general symbol-reading fixups.
2017 * doc/gdbint.texinfo: Add documentation on symbol-reading
2020 * mipsread.c: Remove kludges around #include "ecoff.h".
2021 Remove redefinitions of a_magic, etc, no longer used.
2022 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
2023 Fix global overview comments to match symfile.c protocol.
2024 (mipscoff_new_init): Eliminate cur_hdr if we have one.
2025 (mipscoff_symfile_read): Eliminate unused code. Avoid
2026 sorting all the symtabs, when all we have read here is psymtabs.
2027 The symtabs are sorted as they are created anyway. Tell
2028 condense_misc_bunches whether we're mainline.
2029 (psymtab_to_symtab_1): Pass filename when recursing, to make
2030 stack trace more informative.
2031 (parse_partial_symbols): Assume cur_hdr as argument.
2032 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
2033 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
2034 the TYPE_NAME of char *, since that's done in symfile.c.
2035 (free_numargs, parse_symbol, add_symbol, add_block,
2036 shrink_linetable): Declare these fns void.
2037 (upgrade_type): Convert tree of if's to switch. Clean up
2038 bogus "off == 0" handling with a complaint. Avoid setting
2039 field bitpos and bitsize of array with lower and upper bounds.
2040 Check specified bitsize of elements against their actual type's
2041 bitsize, and complain if different. Complain about unknown
2043 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
2044 (psymtab_to_symtab_1): Print names of subsidiary files that
2045 are being read in. FIXME, we read far too many files. This code
2046 is not the problem, the problem is in parse_fdr where the psymtabs
2048 (cross_ref): Result should indicate that we used one aux entry
2049 normally, or two if we encountered a "next" entry. This used
2050 to leave the caller pointing at the wrong aux entry.
2051 (add_symbol): If overflowed cur_block, reallocate it larger,
2052 chase all pointers to it, and complain(), rather than clobber memory.
2053 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
2054 (new_field): Only allocate one field initially, not two.
2055 Pull ++ out of macro argument. Simplify.
2056 (_initialize_mipsread): Avoid initialization of importd
2057 global_psymbols and static_psymbols.
2059 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
2060 to properly set pst->symtab; avoid searching for it.
2061 (symfile_fns): Improve comments, add a FIXME.
2062 * dbxread.c: Update comments to reflect symfile protocol.
2063 (read_ofile_symtab, end_symtab): Return the symtab.
2064 (psymtab_to_symtab_1): Set pst->symtab.
2066 * coffread.c (coff_symfile_read): tell condense_misc_bunches
2067 whether we're mainline.
2069 * symfile.h (sym_fns): Remove unused sym_discard member.
2070 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
2072 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
2073 the environment variable is not.
2074 * infcmd.c (finish_command): Use filtered printfs.
2075 * cplus-dem.c: Add struct tags to a few unnamed structs.
2076 * valops.c (value_coerce_array): Improve comments.
2077 * valprint.c (type_print_varspec_suffix): Print array size only
2078 if greater than zero.
2079 * m88k-tdep.c: Shift some lines left by one space, that had
2080 apparently been trashed at some point.
2081 * TODO: More things to do, a few got done.
2083 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2085 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
2086 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
2088 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
2089 * expread.y, findvar.c, symmisc.c: Ditto.
2090 * printcmd.c (address_info): Update printed forms of LOC_
2091 symbols. Elim LOC_EXTERNAL.
2092 (print_frame_args): Keep track of param stack offsets before
2093 re-looking up to find the local register param is kept in.
2095 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
2096 Further integration of mipsread into gdb. Eliminate unused
2097 routines, duplicate declarations. Handle static symbols in
2098 psymtabs as well as external symbols. When reading symtabs,
2099 insert symbols into the correct block (global, static, or a local
2101 (read_mips_symtab, parse_partial_symbols): Don't pass useless
2103 (mipscoff_symfile_read): Don't call select_source_symtab.
2104 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
2105 rather than SYMBOL_VALUE.
2106 (parse_external): Comment clobbering of top_stack.
2107 (parse_partial_symbols): Update comments. Allocate and parse
2108 static symbols as well as external symbols. FIXME, enum values
2109 are not handled in this pass, but should be. Inline new_psymbol.
2110 Use SYMBOL_VALUE_ADDRESS.
2111 (psymtab_to_symtab_1): Read symbols into global static block
2112 by default (until enter some function's local block context).
2113 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
2114 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
2116 * source.c (select_source_symtab): Select a source symtab
2117 from either the symtabs or, failing that, the psymtabs.
2118 (list_command): Update error message.
2119 (forward_search_command, reverse_search_command): Use getc, not
2120 fgetc, for speed. FIXME, add comment about buffers that die if
2121 overrun by long line.
2123 * values.c (unpack_field_as_long, modify_field): Avoid shifting
2124 by an entire word, which is not portable, if we have a 32-bit
2125 field. (Code in dbxread.c already turns such bitfields, if
2126 aligned, into ordinary ints, but fixing this will help for other
2127 symbol formats and for future changes.)
2128 * core.c (core_open): Handle ANSI const brain death.
2129 * utils.c (vprintf): Fix varargs typo.
2131 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
2133 * findvar.c (find_var_value): Handle &function better.
2134 * TODO: Document work needed on &fn and &array.
2135 * printcmd.c (print_address_symbolic): New arg is the prefix
2136 to print if a name is printed.
2137 (print_address_demangle): Honor "set print address" now.
2138 Use new arg above to improve spacing of output.
2139 * valprint.c (val_print): When printing function pointers,
2140 print symbolic form too.
2141 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
2143 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2145 * core.c (memory_error): Reword error msg to mislead less.
2147 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
2149 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
2150 parse_partial_symbols): Use newer BFD internals (external_filehdr
2151 and external_aouthdr), byte-swap the fields that we care about
2152 before using them, and make the file header data local to
2153 read_the_mips_symtab rather than global.
2155 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
2157 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
2158 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
2160 * main.c (command_line_input): Flush stdout and stderr
2161 before every call to readline. This reportedly fixes a bug
2162 that comes up in Sys V running emacs-gdb and/or xxgdb,
2163 when stdin/out are pipes or sockets.
2165 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2167 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
2168 Avoid declaring Makefile dependencies, because GNU Make stupidly
2169 tries to update it if we do.
2171 * coffread.c: Revise for minor changes to bfd internal coff
2174 * configure: If -template= is given a relative path, make it
2175 absolute before recurring in subdirectories.
2177 * configure, configure.in, Makefile.in: Install "configure" script
2178 as replacement for config.gdb.
2179 * config.gdb, Makefile.dist, Makefile.sdir: Remove
2180 * README: Update for configure, mostly. FIXME.
2182 * Add dec3100 as equivalent to littlemips. Indicate in all host &
2183 target config files that they are for the host. When the lines
2184 get copied into the Makefile, this makes it more obvious what's
2187 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2189 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
2190 tabs, which end up in the disassembler output inadvertently.
2192 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
2194 Make it compile cleanly in an ANSI GCC2 environment.
2196 * blockframe.c: <stdio.h>
2197 * cplus-dem.c: free takes a void *, ifdef __STDC__
2198 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
2200 * defs.h (alloca): Avoid doing anything if alloca already def'd.
2201 * stddef.h, stdlib.h: Remove these files.
2202 * symtab.c: Avoid declaring qsort, close.
2203 * symfile.c: Avoid declaring close.
2204 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
2205 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
2207 Assorted other changes.
2208 * dbxread.c: include "libaout.h", not "liba.out.h".
2209 * printcmd.c (print_frame_args): Set recurse properly for
2210 indentation of struct and array parameters.
2211 * valops.c (value_cast): Allow cast to void.
2212 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
2213 single_step() in a target-independent fashion.
2214 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
2215 set up to be ready to continue. This makes us target independent.
2216 * infptrace.c (child_resume): Remove call to single_step; now
2217 can single step a SPARC target of any kind.
2219 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2221 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
2222 docn into separate sections---basically chapters, plus two loose
2223 pieces that can be configured to go in different places. This
2224 allows GNU m4 to preprocess the manual without coredumping.
2226 * Makefile.dist: tell TeX where to find texinfo.
2228 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2230 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
2231 the new target "rdl-apps.texinfo" which captures the Makefile
2232 variable that records where to find the Readline libraries.
2234 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
2236 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
2237 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
2238 * defs.h (const, volatile): Only define if not already defined.
2239 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
2241 * README: Update for release 3.95.
2242 * config.gdb: Don't create readline dir in subdir builds.
2243 * main.c: Include with "..." form for non-system include files,
2244 so "gcc -MM" for "make depend" works.
2245 Include readline files with "...h" rather than <readline/...h>.
2246 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
2248 * coffread.c: Undo minor damage done by Rich Pixley. Use
2249 different internal and external representations of COFF
2250 data structures. Use new BFD routines for swapping them in and
2252 * symfile.c (free_named_symtabs): Avoid freeing file names that
2253 are null or empty. Old i960 tools seem to produce files that
2254 claim to have empty names, causing each successive file read
2255 to blow away the previous one.
2256 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
2257 Move deferred_stores to top of file, but don't separate its
2258 #define's from its variable. Add commentary.
2259 * Makefile.dist: Fix Rich damage; undo "configure" changes in
2260 favor of keeping the (working) config.gdb. Move readline
2263 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
2265 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
2267 * infptrace.c (fetch_registers): no result, since now void.
2268 * tconfig/news: target depends on m68k-tdep too.
2270 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2272 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
2275 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
2276 applied various small fixes due to or inspired by RMS comments
2278 * doc/gdb.texinfo: finished using all RMS comments, save those for
2279 appendices on readline and cmd history (which are in other source
2282 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2284 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
2285 chapter 9; (2) documented 'break' command's menu mode for
2286 overloaded names, in response to hgs problem report C++ p-31
2288 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2290 * doc/gdb.texinfo: (1) better introductory example; (2) more
2291 consistent use of @code, @samp, @file, @kbd throughout; small
2292 cleanups to first three nodes; (3) new "Contributors" node;
2293 (4) Appendix, Renamed Commands; (5) divert specialized startup
2294 instructions to "Targets" chapter for generic manuals, while
2295 leaving them up front for manuals specific to specialized
2296 environments; (6) apply fixes from RMS comments through chapter 4.
2298 * pretex.m4: modify explanatory text slightly (and redefine
2299 "regexp") to keep GNU m4 from complaining. (It still crashes
2300 later, but one step at a time...)
2302 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
2304 * readline/readline.c (update_line): Avoid dereferencing a pointer
2305 before comparing it to its bounds. Saber caught this.
2306 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
2307 and only set PC if tgetstr returned non-null. Saber caught this.
2309 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2311 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
2312 stuff for config manual) here where it counts; updated
2313 to use new subdir structure (gdb/doc/).
2315 * Makefile: generated from above via
2319 * gdbint.texinfo: added instructions on generating gdb.info* files
2320 locally for release. These are ordinary info
2321 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
2322 Makefile)---but due to use of texinfo 2, can't count on makeinfo
2323 to generate these, so we distribute them already formatted.
2325 * gdb.texinfo: included full Info node and menu crud (as generated
2326 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
2328 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
2329 put in comments-for-future gdb.info target (one day makeinfo will
2332 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2334 * gdb.texinfo: Updated to include new or old undocumented
2335 commands, at least the following (perhaps some others I forgot to
2336 record): info f, info float, info path, info program, info s, info
2337 set, info source, info terminal, info types, info user, set/show
2339 Also covered all recent GDB command renames for v4.
2341 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2343 * mipsread.c: Rather than keeping count of how many symtabs
2344 and psymtabs we have, for sorting purposes, count them when
2345 we need to sort. This fixes bug in rereading of symbol tables.
2347 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2349 * infcmd.c: renamed "info path" to "show paths"
2350 * gdbrc.tex: documented above.
2352 Wed May 8 04:51:11 1991 John Gilmore (gnu at cygint.cygnus.com)
2354 * remote.c: Fix comments.
2355 * utils.c (error): Force out any pending wrap output.
2357 Sat May 4 11:11:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2359 * Makefile.dist: Roll VERSION to 3.95.
2360 Fix up "saber_gdb" to work again.
2361 * saber.suppress: Update.
2363 * coffread.c, exec.c, infptrace.c, inftarg.c, remote.c, solib.c,
2364 symtab.h, target.c, target.h: Lint.
2365 * core.c: setup and select frame after reading shared libs,
2366 else reading shared libs will clobber them. Lint.
2367 * utils.c (error): Force out any buffered wrap text.
2369 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2371 * remote.c: Remove decls of memory_insert_breakpoint
2372 and memory_remove_breakpoint, no longer used. (Suggestion of
2375 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
2376 to make it easier to interface to "configure"'d libraries.
2378 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
2380 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
2381 aliases for set/show print.
2383 Thu May 2 11:22:02 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
2385 * coffread.c (coff_sym_fns) [TDESC]: Make the type be m88kbcs.
2387 * m88k-tdep.c (IEEE_isNAN): New function.
2389 * infrun.c, m88k-tdep.c, m88k-xdep.c: Change
2390 initialize_{tdesc,dcontext} to init_{tdesc,dcontext}.
2392 * infrun.c [TDESC]: Add a bunch of crud.
2394 * xm-88k.h [__GNUC__]: Don't define memset.
2396 * m88k-xdep.c: #if 0 out push_breakpoint.
2398 * tm-88k.h: Define GET_SAVED_REGISTER.
2400 * tm-88k.h: Define DGUX.
2402 * m88k-opcode.h (UEXT, SEXT, MAKE): Put parentheses around arguments.
2404 * m88k-pinsn.c (sprint_address): Declare at top of file.
2406 * m88k-xdep.c: #if 0 out core_file_command.
2408 * values.c ({unpack_,value_as_}pointer): Just call
2409 {unpack_,value_as_}long (for now anyway).
2411 * m88k-tdep.c (get_saved_register): Make get_reg a dc_word_t (*)().
2412 (psr_register): Change return type to dc_word_t.
2414 * m88k-tdep.c (tdesc_read_function): Comment out call to ptrace.
2416 * m88k-tdep.c (get_saved_register): Add lvalp parameter.
2418 * gdbcore.h (write_memory): Don't prototype it.
2420 * tm-88k.h, m88k-tdep.c: Make stack_error, stack_jmp global.
2421 m88k-xdep.c: Don't mention stack_error.
2423 * {x,t}config/m88k ({X,T}DEPFILES): Add missing files.
2425 * mtrace.c: Don't typedef things like size_t, just #define them.
2427 * coffread.c [TDESC]: #if 0 out references to coffsyn.
2429 * symtab.h (struct symtab): Include EXTRA_SYMTAB_INFO.
2430 tm-88k.h: Define EXTRA_SYMTAB_INFO.
2432 * coffread.c [TDESC]: Include "tdesc.h" and make tdesc_handle

2901 (_initialize_values): Rename "info directories" to "show directories".
2903 * values.c: Rename convenience_info to show_convenience.
2904 (_initialize_values): Rename "info convenience" to "show convenience".
2906 * copying.awk (_initialize_copying): Rename "info copying" to
2907 "show copying" and "info warranty" to "show warranty".
2908 Rename {copying,warranty}_info to show_{copying,warranty}.
2910 * symfile.c: Rename add_syms_command to add_symbol_file_command.
2911 (_initialize_symfile, add_syms_addr_command):
2912 Rename add-syms to add-symbol-file.
2914 Thu Apr 18 18:08:30 1991 John Gilmore (gnu at cygint.cygnus.com)
2916 * symfile.h (free_named_symtabs): Rename from free_named_symtab.
2917 * symfile.c (clear_symtab_users_once, cashier_psymtab,
2918 free_named_symtabs): Move these routines from symmisc.c.
2919 * symmisc.c (same): same.
2920 (free_symtab): Make non-static.
2921 * symtab.h (free_symtab): Declare as exported void fn now.
2922 * dbxread.c (end_symtab, end_psymtab): Change comments.
2923 (initialize_dbxread): Call dbx_new_init() in case the first
2924 command is add-symbols.
2925 * target.c (dummy_target): Permit add_syms_addr_command.
2927 Sat Apr 13 14:46:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2929 Permit symbols to be superseded when new symbol files have
2930 been read in, particularly for VxWorks.
2932 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
2933 to the main file, as well as to include files. Also, put global
2934 functions into the global psymtab, to make "i fun" work.
2935 (end_psymtab): Free named symtabs and psymtabs for a file, once a
2936 new psymtab for it has been read.
2937 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
2938 a file, once a new symtab has been read for it.
2939 * mipsread.c: FIXME. We need to do the same for MIPS, but it
2940 looks harder to determine the top-level block before it's been
2941 queued to the psymtab list.
2943 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
2944 If we have wiped out any old symbol tables, clean up at end of
2946 (symbol_file_command): Don't reference symfile_fns if it's zero.
2948 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
2949 defines for the blocks of a blockvector that contain global and
2950 file-static symbols and the first of the smaller scope contours.
2951 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
2952 decode_line_1, make_symbol_completion_list): Use the above.
2953 * coffread.c (end_symtab, patch_opaque_types): Ditto.
2954 * dbxread.c (end_symtab): Ditto.
2955 * expread.y (block): Ditto.
2956 * mipsread.c (throughout): Ditto.
2957 * symmisc.c (free_named_symtabs): Ditto.
2959 * symtab.c (list_symbols): Process the first symbol of the
2960 static psymbols list.
2961 (types_info): Restore this function from its untimely #if 0.
2962 It's not perfect, but it is better than nothing.
2963 (_initialize_symtab): Restore "info types".
2965 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2967 * m68k-stub.c: Remote stub for 680x0's, created from
2968 rem-m68k.shar (which is removed).
2969 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
2970 Remove RCS log stuff now that we use CVS and it blows our diffs.
2972 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2974 * symmisc.c (free_named_symtab): Make it work, in its current
2975 kludgy fashion. Change result to indicate if we blew away bkpts.
2976 * dbxread.c (end_symtab): Accumulate result from
2977 free_named_symtab and print warning if we blew user's state.
2978 * symfile.h: free_named_symtab now returns an int.
2980 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
2982 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
2983 is the first symbol read, even if not mainline.
2984 (dbx_psymtab_to_symtab): symfile might be zero, cope.
2985 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
2986 (set_section_command): New command ("section xxx yyy" -- should
2987 be renamed to "set section xxx yyy" FIXME) which sets the
2988 base address of a section of the exec file, overriding the
2989 virtual address that BFD reports.
2991 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2993 * exec.c: Add add_syms_addr_command to exec_ops, so you can
2994 load symbols at any address while examining an exec file.
2996 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
2998 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
2999 for printing the float info is host-dependent, not
3000 target-dependent. FIXME.
3001 * i386-pinsn.c: Move #includes to top, remove useless ones.
3002 * i386-tdep.c: Don't bother including <.../reg.h> since we
3003 don't use it (and it doesn't exist on host systems).
3005 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
3006 Convert negative numbers properly.
3007 (ieee_test): Make numbers really random; fix format arg.
3009 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
3010 * core.c (core_detach): Unpush core_ops, which might not be on
3011 top. We used to just pop the top, which broke things. Don't
3012 need dont_repeat() any more.
3013 (core_file_command): Psst! Don't repeat it.
3014 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
3015 * expprint.c (print_subexp): Avoid switch fallthru on
3016 BINOP_ASSIGN_MODIFY, so we can print += and such.
3017 * frame.h: Fix typo.
3018 * inflow.c (kill_command): After killing inferior, print our
3019 current frame in the core file, if we have one.
3020 (generic_mourn_inferior): When inferior dies, either select
3021 the current frame (in the new target, e.g. core file), or
3022 set both the current and selected frames to NULL.
3024 Changes from Peter Schauer.
3026 * infptrace.c: Avoid <sys/ptrace.h> on USG.
3028 * Make all file names fit in 14 characters (sigh and damn!):
3029 mv hp300hpux-xdep.c hp300ux-xdep.c
3030 mv symmetry-xdep.c symm-xdep.c
3031 mv symmetry-tdep.c symm-tdep.c
3032 mv convex-opcode.h convx-opcode.h
3033 mv tm-vxworks960.h tm-vx960.h
3034 mv tm-vxworks68.h tm-vx68.h
3035 mv Makefile.srcdir Makefile.sdir
3036 mv gdb-int.texinfo gdbint.texinfo
3037 mv remote-sa.m68k.shar rem-m68k.shar
3038 mv remote-multi.shar rem-multi.shar
3039 * Makefile.dist, README, config.gdb, convex-pinsn.c,
3040 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
3041 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
3044 * command.c (user_info_1, user_info): New command for listing
3045 the user-defined commands.
3047 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
3049 * dbxread.c (really_free_pendings): Clear file_symbols
3050 and global_symbols after freeing them; otherwise, running
3051 this function twice (if it appears twice on the cleanup
3052 chain), we try to free things twice.
3054 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
3055 based on text_addr (the address of text in core), not on addr (the
3056 offset between text in the .o file and in core). This change
3057 is from Peter Schauer.
3059 * main.c: Define ALL_CLEANUPS as a cast of zero.
3060 (return_to_top_level): Use it.
3061 (main): Do all cleanups after each command run as part
3062 of the gdb startup sequence. Also do all cleanups before
3063 entering the command loop, and every time we exit the command
3064 loop and reenter. Before, the cleanups from the startup sequence
3065 were being left undone until the first error!
3066 (command_loop): Rename do_nothing cleanup to command_loop_marker
3067 so we can see it easily when examining the cleanup chain.
3068 (init_signals): Add another do_nothing for signal handling.
3069 (quit_command): Only try to kill target if it has execution.
3070 Problems in the target stack got us into a state where
3071 inferior_pid was nonzero but none of the targets had execution.
3072 In this state you couldn't exit gdb.
3074 * dbxread.c: Two changes from Peter Schauer.
3075 (echo_command): Fflush output after an echo command.
3076 (show_history): Pass all args to cmd_show_list.
3078 * utils.c (init_malloc): Call mtrace to turn on tracing
3079 if the environment variable MALLOC_TRACE is set to a file name.
3080 * mtrace.c: Add source file which provides a log of every malloc,
3081 free, and realloc to a trace file.
3082 * mtrace.awk: Add source file which analyzes the trace file.
3083 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
3084 (VERSION): Roll to 3.94.3.
3086 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
3087 (check_duplicates): Don't bother with watchpoints.
3088 (set_raw_breakpoint): Comment about danger of this routine.
3089 (watch_command): Parse and eval all args before calling
3092 * solib.c (find_solib): Avoid error in referencing memory to
3093 see if any more shared libraries have been added. This is
3094 particularly useful if the target has terminated. Bug reported
3097 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
3098 in bringing up 3.94.2 on the Sun-3.
3100 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
3101 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
3102 expression (in scope) before reenabling watchpoint.
3103 * signame.c (init_sigs): Add missing declaration of i, fix
3104 sys_siglist declaration.
3105 * source.c (list_command): Fixed range computation to use
3107 * stack.c (backtrace_command): Do not allow command if target has
3108 no stack, print informative error message.
3109 * target.c (target_command): Do not write into command line
3110 because this fails if the target command is used in a user defined
3111 command. [This change was enhanced by gnu to support any-
3112 unique-prefix matching on target names.]
3113 * valops.c (value_struct_elt): Avoid infinite loop on an
3114 erroneous attempt to print the member of function (try p main.p).
3116 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3118 * expread.y (name_no_typename): Avoid reduce/reduce errors
3119 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
3120 Since the GDB parser really doesn't use name_no_typename in a
3121 name-only context, the parser can't tell the diff between
3122 names and numbers here. Avoid allowing a name_no_typename
3123 to be a NAME_OR_*INT to resolve the conflict.
3125 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3127 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
3129 * valprint.c (val_print_fields): bitfield printing didn't handle
3130 byte order. Indirect through a few more fns to cope.
3132 * values.c (modify_field): also cope with byte order.
3134 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
3136 Cleanup for release 3.94.2:
3138 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
3139 include files. Roll version to 3.94.2.
3141 * coffread.c (init_stringtab): Read length into unsigned char
3142 array before swapping; don't assume 32-bit longs.
3144 * target.c (target_info): Don't bother with get_sym_file, just use
3145 the symfile global variable.
3146 * symtab.h, symfile.c (get_sym_file): Delete it.
3148 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
3149 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
3150 (read_type): Replace one more error() with complain().
3152 * mipsread.c (parse_partial_symbols): Replace printf with complain.
3154 * i960-tdep.c: Fix copyright attribution.
3156 * config.gdb: Quote all backquotes in doublequotes. You can
3157 quote me on that. BSD 4.4 shell found this one.
3159 * infptrace.c (throughout): The third argument to ptrace is an
3162 * infrun.c (wait_for_inferior): When program has terminated, we
3163 have to call target_terminal_ours before we pop that target off
3164 the stack (e.g. before a call to target_kill or
3165 target_mourn_inferior). This fixes problem where a program
3166 terminates, then GDB stops for (tty output) and you have to type
3167 "fg" to the shell to resume it. FIXME: This code for what to
3168 do after termination really should be in normal_stop instead.
3170 * gdbcore.h (read_memory_check): Change declaration; it changed
3173 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
3174 4.4 prereleases, this avoids a bug in their sgtty compatability
3176 * remote.c: Use terminal.h rather than hand-rolling the same.
3178 * signame.c, signame.h (psignal): Arg is unsigned, not int.
3179 * utils.c (strsave, strstr): Fix arg types.
3180 * valprint.c (val_print): lint
3182 MIPS symbol table support from Per Bothner:
3184 * symfile.c (symtab_fns): Remove initializer table that needs to
3185 be hacked for each new symbol file format supported.
3186 (add_symtab_fns): New function, chains symbol table
3187 handlers into the global list.
3188 (symfile_init): Search this list.
3189 * symfile.h: Add next pointer, declare add_symtab_fns.
3190 * coffread.c (_initialize_coffread): Call add_symtab_fns.
3191 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
3193 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
3194 symbol *). Thus, we no longer need the hack to trash
3195 pst->filename. Good, since that hack confused code in symfile.c!
3197 (reorder_symtabs, destroy_all_symtabs): Removed static
3198 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
3199 Instead, the latter now uses a temporary array (stack-allocated
3200 from an obstack, and then freed).
3202 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
3203 haven't been set in the outermost stBlock of a procedure. This was
3204 a problem with f77 binaries on Ultrix 4.?.
3206 (new_symtab, new_symbol, new_type): Continue changing code to use
3207 obstacks more and otherwise conform to dbxread internal style.
3208 Made the free_code of symtabs be free_linetable (as in dbxread)
3209 instead of free_contents. This implies memory leaks when reading
3210 a new symbol table, until the conversion is finished. Did change
3211 (struct symbol) and (struct type) to be allocated on the
3212 symbol_obstack. Blocks and blockvectors are among the things
3215 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
3216 tested much, but it solved one problem (reported by Meissner), and
3217 cleans up some other things. The problem happened when an
3218 included file contains actual code (functions) and not just
3219 definitions. The mips coff is a little inconvenient there, since
3220 it may cause a procedure to be mapped to the wrong psymtab.
3222 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
3223 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
3224 this will need work for the new core paradigm.
3226 Opcode patches from the net:
3228 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
3229 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
3230 missing altogether - they are added here. From Bruce Bauman.
3231 * mips-opcode.h: The low mask for C0 instructions was too small.
3232 From Garrett Lau. I modified the fix to check the entire 32-bit
3235 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
3238 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3240 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
3242 * dbxread.c (read_type): Pointer subtraction (value_sub in
3243 valarith.c) sometimes failed because the types of the
3244 pointers being subtracted were not identical.
3245 These differed because dbxread.c was allocating pointer types
3246 using dbx_alloc_type+smash_to_pointer_type instead of
3247 lookup_pointer_type. I failed to find a justification for the
3248 former, so I changed it to use the latter. Similarly, I
3249 replaced smash_to_function_type by lookup_function_type,
3250 and smash_to_reference_type by lookup_reference_type.
3252 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
3253 _initialize_mipsread): corresponding changes.
3255 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
3257 * source.c (mod_path): Do tilde_expand on each component of the path,
3258 rather than on the (list of) paths as a whole.
3259 (print_source_lines): Set first_line_listed in addition to
3260 current_source_symtab and current_source_line. If the source was
3261 not findable, after a "dir" command to fix the problem,
3262 a "list" would get the wrong lines.
3264 While I was there... (gnu):
3266 * dbxread.c (read_type): Change error to complaint.
3268 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3270 First attempt at detailed understanding of symbol table memory alloc.
3272 * dbxread.c (dbx_symfile_read): Free our string table if we
3273 aren't the mainline. Free the "info" struct since we're done with
3275 (init_psymbol_list): Free any previously allocated psymbol lists.
3276 (): FIXME: Should realloc-down the psymbol lists when done reading
3277 the main symbol file?
3279 * symmisc.c (free_symtab): Free fullname field too.
3281 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
3282 (REGISTER_ADDR): Make result type unsigned int.
3284 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
3285 define REGEX must also define REGEX1 (its dependency).
3287 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
3289 * tconfig/i960: No longer works, points you at vxworks960 or
3292 * xgdb.c, XGDB-README: Remove file. Users can get the much
3294 * Makefile.dist: Remove all trace of xgdb.
3296 * breakpoint.c (breakpoint_1): Pass demangle arg to
3297 print_address_symbolic.
3298 (clear_breakpoints): Remove unused function.
3299 (breakpoint_re_set_one): Guts of breakpoint_re_set.
3300 (breakpoint_re_set): Use catch_errors to do them all anyway.
3302 * gdb-int.texinfo (Host versus Target): Add section on what is
3303 a "host" feature versus what is a "target" feature.
3305 * infcmd.c (path_command, path_info): Handle the PATH variable
3306 (object search path) as conveniently as the source search path.
3307 * environ.c (set_in_environ): Set some vars in GDB's environment,
3308 in addition to the child's. PATH, G960BASE, G960BIN for starters.
3309 * source.c (mod_path): New function, from guts of
3310 directory_command, modifies a path. Used by path_command.
3311 (directory_command): Call it.
3312 * defs.h (strsave): Declare.
3314 * utils.c (sevenbit_strings): Add new printing option.
3315 (printchar): Use it.
3316 (strsave): Provide this handy helper routine.
3317 (set_width_command): Rename set_screen_width_command.
3318 (_initialize_utils): "set screen-width" => "set width";
3319 "set screen-height" => "set height"; add sevenbit-strings.
3321 * infcmd.c (do_registers_info): Print floating point registers
3322 in raw hex as well as float format, regardless of whether it is
3323 a "virtual" convertible register.
3324 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
3325 regs as a double, just in case it's being used that way.
3326 * values.c (unpack_long): Comment on array/function coercion.
3327 (unpack_double): Argument is in target byte order now. For
3328 integer arguments, just call unpack_long and float the result.
3329 * m68k-tdep.c: include defs.h for "const" handling.
3330 * remote-nindy.c: Use ieee-float stuff.
3331 (nindy_fetch_registers): Unpack double regs to host double, then
3333 (nindy_store_registers): Pack extendeds to host double, flip
3334 around by misusing unpack_double, send as target double.
3336 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
3337 zero, as when stopped at the first instruction of a process.
3339 * blockframe.c: Fix filename in comment (param.h => tm.h).
3340 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
3341 * tm-68k.h: Fix typos.
3343 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
3345 Changes from a bringup on the DEC Vax under Ultrix 4.0.
3347 * coredep.c (fetch_core_registers): Pass end-address of register
3348 section to register_addr as expected. Don't call supply_register
3349 if we'd just pass it garbage.
3351 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
3353 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
3355 * target.c (push_target, target_info): Cast enums to int for < or
3358 * stack.c (print_frame_info): Identify source file & line
3359 even if we can't print it.
3361 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
3363 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
3365 Clean up IEEE floating point support.
3367 * ieee-float.h: New file.
3368 * ieee-float.c: Write real routines to convert between host
3369 doubles and various target IEEE extendeds.
3370 * m68k-xdep.c: Eliminate assembler code for extended floats.
3371 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,

3373 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
3374 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
3375 double_to_ieee_extended.
3376 * i960-tdep.c: Define ext_format_i960.
3377 * m68k-tdep.c: Define ext_format_68881.
3378 * sparc-tdep.c: Define ext_format_sparc, though unused.
3379 * Makefile.dist (HFILES): Add ieee-float.h.
3380 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
3383 Obsolete the "coffstrip" program in favor of using BFD's strip.
3385 * nindy-share/coffstrip.c: Remove file.
3386 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
3387 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
3388 * tconfig/nindy960: Remove reference to coffstrip.o.
3390 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
3392 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3394 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
3395 * dbxread.c: Remove static symfile_bfd.
3396 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
3398 * inftarg.c (child_detach): Pop the child_ops vector if the
3399 detach is successful.
3400 * remote-nindy.c (nindy_create_inferior): Don't push a new
3401 nindy_ops since nindy uses the same one for execution and memory
3403 * core.c (core_ops): Use child_attach and child_create_inferior
3404 rather than default attach and create_inferior functions.
3406 Handle floating point registers in core files.
3408 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
3409 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
3410 This version untested since BFD doesn't yet support sun3 core
3412 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
3413 conventions. Fix comments and style. This version has not
3414 been compiled yet, since we have no HP inhouse.
3415 * core.c (get_core_registers): Look for two sections, ".reg"
3416 and ".reg2", and pass both to fetch_core_registers sequentially.
3418 Revise directory path yet again.
3420 * source.c (forget_cached_source_info): Not static any more.
3421 (init_source_path): New default source path is "$cdir:$cwd".
3422 (dir_command): Handle variable arguments ($cdir, $cwd).
3423 (source_info): Print "Compilation directory" rather than
3424 "Originally compiled in" to remind people of $cdir.
3425 (openp): If the path contains $cwd, use current directory.
3426 (open_source_file): If compilation directory is known, replace
3427 first $cdir in path with the compilation directory.
3428 (print_source_lines): Even if we can't print the lines, set the
3429 current symtab and line for future commands like "info source" or
3430 "breakpoint". Also, error message now contains the file name,
3431 line number, and file access error message.
3432 (_initialize_source): Fix help text to describe changes.
3433 * main.c (cd_command): Forget cached source info when we chdir.
3434 * utils.c (strstr): Add simple implementation.
3436 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
3438 * coffread.c (read_one_sym, init_linetable, init_stringtab):
3439 Byte-swap COFF symbol tables if necessary when reading them in.
3440 Use complain() to replace error message in one spot. Needs
3441 corresponding change in bfd/coff-code.h to make some symbol
3442 swapping routines non-static.
3444 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3446 Merge changes from Eirik Fuller, for UTek.
3448 * defs.h (errno): Add declaration.
3449 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
3450 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
3451 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
3452 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,

3454 declarations of errno.
3456 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
3458 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
3459 <rpc/rpc.h> and <rpc/types.h>.
3461 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
3463 * i960-tdep.c (examine_prologue): Add new argument limit,
3464 which stops the scan at the end of the prologue, or at the PC.
3465 This fixes a problem where it walks down into the code for the
3466 user's statements if that code looks like function prologues.
3467 Mark Fox and I have been bouncing this code back and forth, making
3468 small changes to it. Callers changed to match.
3470 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
3472 Cleanup for gdb-3.94 release final:
3474 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
3475 the .c files from vx-share and nindy-share, from the various
3476 macros, since they are not found via ALLDEPFILES.
3477 (SFILES): Add tm-i960.h.
3478 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
3479 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
3481 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
3482 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
3484 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
3486 * am29k-tdep.c: Add contribution line.
3487 (examine_prologue): Cache information about function prologues in
3488 the misc-function-vector to avoid lots of references over the
3489 serial line while examining instructions.
3491 * core.c (core_close): New function made from cleanup_core.
3493 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
3494 remote-vx.c, remote.c, target.c, target.h,
3495 Update target_ops vector to add attach, close, and load entries.
3496 Use add_syms_addr_command, not add_file_addr_command, for
3497 add_file. Break out close routine from existing code.
3499 * dbxread.c (really_free_pendings): Don't free pending_blocks;
3500 they are in an obstack.
3501 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
3503 (define_symbol): Add symbol type parameter; change callers;
3504 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
3505 it to influence the symbol class on the i960.
3506 (define_symbol): Swap LOC_CONST's into target byte order.
3508 * exec.c (exec_close): New function.
3509 (exec_file_command): Call it.
3511 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
3512 Fix byte order of frame pointer.
3513 (read_var_value): Result of 0 if var's value can't be found,
3514 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
3515 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
3516 (locate_var_value): Use read_var_value and use its lazy address
3517 as the location of the var's value. Lint.
3519 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
3522 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
3523 obsolete Intel versions in favor of vxgdb versions.
3524 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
3525 code dealing with byte order of values, which Intel did in host byte
3526 order rather than gdb-4's target byte order.
3527 (i960_frame_chain_valid): Move to nindy-tdep.c.
3528 (examine_prologue, skip_prologue, frame_find_saved_regs,
3529 frame_args_address, leafproc_return, saved_pc_after_call,
3530 pop_frame): Add vxgdb versions from Mark Fox.
3531 (examine_prologue, frame_struct_result_address): Add code
3532 to deal with the saved value of G13 (struct return address
3534 (frame_args_address): Modify Mark's version to prefer the
3535 saved value over the current value in the topmost frame.
3536 Cache result in the frame info to avoid performance hair in
3538 (print_fault): Add gdb960 code for printing faults.
3539 (_initialize_i960): Actually call check_host.
3541 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
3542 add stub routines. FIXME, these currently just return zero!
3544 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
3545 (attach_command): Call target_attach, not target_open, now.
3547 * infrun.c (normal_stop): Make global, not static, for vx_attach.
3548 (child_attach): Rename from child_open.
3549 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
3550 don't confuse it with a zero step_resume_break_address.
3552 * inftarg.c (child_detach): Eliminate inferior_pid test.
3553 (child_files_info): Clean up message a bit.
3554 (child_ops): Use child_attach, not child_open, to attach.
3556 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
3557 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
3558 findvar.c to here, since it depends on the contents of the
3559 shadow_contents of breakpoints, but keep if #if 0 since it is
3562 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
3565 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
3566 (ptype_command, display_command): Eliminate have_inferior_p and
3567 have_core_file_p in favor of target_has_stack or
3568 target_has_execution.
3569 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
3570 code for actually finding the values of arguments, though we still
3571 keep track of the maximum stack offset for use in printing unnamed
3572 arguments. Handle missing FRAME_ARGS_ADDRESS.
3574 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
3575 (struct nindy_regs): Define registers passed to/from nindy.
3576 (nindy_fetch_registers, nindy_store-registers): Translate between
3577 nindy and GDB formats for the registers.
3578 (dcache_init): Statically allocate the cache, since it was being
3579 allocated by a malloc that was never freed anyway.
3580 (nindy_create_inferior): Error, not core dump, if no exec file.
3581 (nindy_before_main_loop): Use target_load, not target_add_file.
3583 * remote-vx.c (net_load): Specify large timeout for load
3584 requests. Allow user to break out with INTERRUPT.
3585 (net_break): Remove useless code, clean up. Change callers.
3586 (parse-args, skip_white_space, find_white_space): Clean up arg
3587 parsing to cope with quoted strings.
3588 (net_wait, net_quit): Never call error, just return status.
3589 (vx_read_register, vx_write_register): Cleanup status checking.
3590 #ifdef the code based on which CPU we are using (960 or 68k),
3591 FIXME, this should be completely general but it isn't yet.
3592 (vx_xfer_memory, vx_resume): Cleanup status checking.
3593 (vx_run_files_info): Improve message.
3594 (vx_load_command): Renamed from vx_add_file_command. Allow load
3596 (net_ptrace): Remove unused routine.
3597 (vx_wait): Adopt code from vxgdb960 to cope with broken
3598 connections to target machine and prompt to disconnect. Remove
3599 debug printouts. Map some EVENT_'s to SIGnals.
3600 (add_symbol_stub, vx_open): Print names of object files we found,
3601 and "ok" if we read their symbols OK. Clarify output in general.
3602 (vx_attach, vx_detach, vx_kill): Add these commands.
3603 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
3604 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
3605 "info files" output, and create_inferior, since we already have
3608 * stack.c (frame_info): Replace Frame_unknown with 0.
3609 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
3610 (return_command): Pop until the PC matches as well as the FP,
3611 so it works even if the FP is shared with another function,
3612 as in "frameless" or "leaf" procedures.
3614 * symfile.c (load_command): renamed from add_file_target_command.
3615 (add_syms_addr_command): renamed from add_file_addr_command.
3616 (add_syms_command): Stub to call target_add_syms.
3617 (_initialize_symfile): Change command names and descriptions,
3618 add-file => add-syms, and load from alias to its own command.
3620 * target.c (kill_or_be_killed, maybe_kill_then_attach,
3621 maybe_kill_then_create_inferior): Default for attempts to start
3622 a process, if one is already running, is to ask about killing
3623 it and retry if yes.
3624 (upstack_create_inferior): #if-0 it, strata obsolete it.
3625 (push_target, unpush_target, pop_target): to_close() a target
3626 before unstacking it.
3627 (target_info): Renamed from target_files_info.
3628 (_initialize_targets): Rename "i files" as "i target", accessible
3631 * target.h: Improve comments about the target_ vectored routines.
3633 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
3634 Convert commenting style to standard GNU style.
3635 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
3636 (SKIP_PROLOGUE): No longer a no-op.
3637 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
3638 (*_REGNUM): Sort register numbers.
3639 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
3640 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
3641 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
3642 are now 10 byte extendeds, not 8 byte doubles.
3643 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
3644 for nindy versus vxworks targets. FIXME, this should possibly go
3645 in the target vector.
3646 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
3647 frame_saved_regs and arg pointer with each frame.
3648 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
3649 (FRAME_ARGS_ADDRESS): Use cached result.
3650 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
3651 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
3652 (PRINT_RAMDON_SIGNAL): Call print_fault.
3653 (POP_FRAME): Now works.
3655 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
3656 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
3657 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
3658 (ADDITIONAL_OPTION_HANDLER): use target_load, not
3661 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
3662 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
3664 * valarith.c (value_subscripted_rvalue): Avoid handling
3665 floats and doubles specially; it gave alignment errors. Lint.
3667 * valops.c (value_of_variable, value_of_this): Error if unknown
3670 * valprint.c (print_floating): Bcopy rather than pointer-deref,
3671 to avoid alignment problems.
3672 (value_print): Handle unknown value address.
3673 (cplus_val_print): Two args are ignored; remove them. Change caller.
3674 (val_print): Use unpack_long rather than pointer-deref.
3677 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
3678 to avoid alignment problems.
3679 (value_being_returned): Error if return value unknown.
3680 (set_return_value): Add bogosity warning, FIXME. *
3682 * TODO: A woman's work is never done.
3684 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
3685 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
3686 Add ieee-float.o to OBS.
3687 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
3688 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
3689 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
3691 Changes to generalize the VxWorks RPC protocol slightly, to handle
3692 i960 as well as 68000.
3694 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
3695 * vx-share/reg.h: Produce i960 regs #ifdef I80960
3696 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
3697 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
3698 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
3699 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
3700 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
3701 so they will move in target byte order rather than network
3702 byte order (happens to be the same).
3704 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
3706 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
3708 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
3711 Add contribution lines to various files, showing where they
3714 * breakpoint.c (break_insn, check_break_insn_size,
3715 read_memory_nobpt): Remove to mem-break.c.
3717 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
3720 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
3721 entry has bad register number. This change is not
3722 tested in this release, FIXME.
3724 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
3727 * value.h: Force value's contents field to be aligned to hold
3728 at least a double or a long long (if supported). This avoids
3729 doing bcopy's in and out of the contents field.
3731 (step_1): Avoid coredump under obscure circumstances when we
3734 * symtab.h (misc_info): Add field to misc function vector for
3735 any kind of cached information the target code desires. AMD
3736 29000 uses this to avoid repeating examine_function_prologue's.
3738 * coffread.c: Lint. Remove static symfile, read_section_header.
3739 core.c (have_core_file_p): Lint: remove.
3740 expprint.c (print_subexp): Lint.
3741 infptrace.c, valops.c, valprint.c: lint.
3743 Roll in changes from vxgdb-5.0.1:
3745 * symtab.h: Comment byte order of each address class. Add
3746 LOC_LOCAL_ARG for frame-relative args (960).
3747 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
3748 symtab.c, symmisc.c: ditto.
3750 * infrun.c (init_wait_for_inferior): Clear stop_signal.
3752 * remote.c (remote_resume): Error if resume with a signal.
3754 * symfile.c (prim_record_misc_function): Clear misc_info.
3755 (fill_in_vptr_fieldno): Check stub type of arg.
3757 * valops.c (value_cast): Avoid looking up names of types whose
3758 name we don't know, to prevent coredump. Sun CC produces typedef
3759 rtx and the name of *rtx is zero...
3761 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3763 Roll in changes from final AMD 29000 port (Tiemann).
3765 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
3766 for ../include/a.out.encap.h. This might not work now that BFD
3767 is separately compiled. Instead, BFD support for encap will have
3768 to translate machine type 29k into the right COFF_MAGIC.
3770 * infcmd.c: Remove references to inferior_pid that aren't used
3771 in actual ptrace calls; use target_has_execution, etc.
3772 (have_inferior_p): Remove function.
3773 (program_info): Print target info rather than "process number";
3774 avoid gratuitous messages unless from_tty.
3775 (run_stack_dummy, finish_command): Set proceed_to_finish.
3776 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
3777 main.c: Lint. Lose have_inferior_p().
3778 inferior.h (have_inferior_p): Remove, lint.
3779 (proceed_to_finish): Add flag to ask that all regs be saved
3780 by normal_stop, for the few commands that need it, speeding up
3781 serial I/O. Add comments to stop_registers.
3783 * remote-eb.c: Remove newline from breakpoint message we grep
3784 for. Never time out when running the user program.
3788 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3790 Roll in changes from vxgdb-5.0.1:
3792 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
3793 symbol in its raw form, we are processing an unlinked ".o" file.
3794 See if the target environment has assigned it an address, using
3795 target_lookup_symbol (VxWorks does), and enter it into the symtab
3798 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
3799 68k versions for a simpler version that assumes zero FP at bottom.
3800 Fixes bug of truncated stack reports.
3802 * target.h (target_lookup_symbol): Define this routine's args
3803 and result, finally.
3805 * target.c (nosymbol): Default routine for target_lookup_symbol.
3806 (target_default): Default lookup_symbol and call_function too.
3807 (files_info): Only print has_all_memory warning if a non-dummy
3810 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
3811 vx_convert_from_virtual): If target does not have floating point,
3812 zero register "values", and avoid doing cross-net conversions.
3813 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
3814 (vx_open): Rearrange code that attaches to target and reads
3815 symbols for all loaded modules, to work if some of the modules
3816 are not accessible. Add symbol_stub() and add_symbol_stub()
3817 as callbacks from catch_errors(). Allow connect attempt to be
3818 interrupted painlessly with ^C (FIXME, there are still some bugs
3819 if the interrupt happens during symbol reading.). Print
3820 final message with puts_filtered, since symbol messages are
3825 * main.c (catch_errors): Only print errstring if non-null.
3826 (command_loop): Avoid an ioctl per command to test ISATTY.
3828 * remote-vx.c (net_load): make static; avoid sophomoric msg.
3829 (vx_xfer_memory): Return correct result!
3830 (vx_files_info): Indicate whether target has float or not.
3831 (vx_lookup_symbol): Complain, not error, if target gone.
3832 (vx_open): Print "Connected" msg before disabling immediate-quit.
3833 [FIXME: lookup_symbol and vx_open changes need testing.]
3835 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
3836 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
3837 contributor lines and update copyrights to 1991.
3839 Changes from an attempted H-PUX host port:
3841 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
3842 defines PT_ATTACH and PT_DETACH but not PT_KILL.
3843 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
3844 * remote-vx.c: include <sys/time.h> for HPUX.
3845 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
3846 "core_file_command" routine to BFD regime. May not work yet.
3848 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
3850 * xgdb.c: Replace X10 version with some VJ version.
3851 (FIXME: Its copyright assignment is not on record.)
3852 * xgdb.c: Update include files to X11R4 (Xaw crud).
3853 (xgdb_display_source, create_text_widget): fix call to
3854 get_filename_and_charpos. Rewack source window stuff for X11R4
3855 (gleaned from include files, and "nm's" of binary libraries, since
3856 I had no doc available).
3857 (append_selection, append_selection_word): Disable with FIXME
3858 since R4 changed interface here.
3859 (create_buttons): Add back the old set of buttons.
3860 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
3862 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
3863 Roll VERSION to 3.94 (not yet final though).
3865 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3867 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
3868 obstack_int_grow, obstack_int_grow_fast): Eliminate
3869 cast on left of assignment, which gives MIPS cc fits and is
3872 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
3873 F_ALIAS. Use printf, not fprintf, when not passing a file
3875 (compare_opcodes): Check that identical instructions have
3876 identical opcodes, complain otherwise.
3878 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
3879 was reported by Roland McGrath.
3880 (unimp): Only match if exactly zero instruction. (Roland)
3881 (branches and traps): Generate all variations of these
3882 instructions with macros, based on a single call that defines
3883 each condition name and its binary representation.
3884 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
3886 * valprint.c (val_print_fields): Take, and use, format parameter.
3887 This means that "p/x struct" again prints the elements in the
3888 desired format. Changed callers.
3890 * stack.c (frame_info): Use filtered output, and indicate wrap
3891 points. Remove kludgy formatting designed to avoid line wrap.
3893 * utils.c (wrap_here): If the line is already full (because
3894 we had printed a long indent or long wrapped string), do an
3895 immediate newline-and-indent.
3897 * m68k-pinsn.c (print_insn_arg): Bugfix from
3898 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
3899 instruction is incorrectly disassembled as bkpt #8.
3901 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
3902 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
3903 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
3904 and then will dump core (sometimes). I traced it back to an
3905 uninitialized symfile_name in psymtab_to_symtab.
3906 (const_vol_complaint): Add quotes to message.
3907 (define_symbol): Only believe line number if gcc_compiled.
3908 Avoid allocating symbol if we will not return it.
3910 Add target strata support so that newly established targets go
3911 into their right place in the target stack (e.g. a new exec file
3912 doesn't wipe out the ability to access the running process).
3914 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
3915 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
3916 and initialize it properly in all the targets.
3918 * target.h: Document strata. Change return type of push_target.
3920 * target.c (nomemory): new function for dummy memory access.
3921 (tcomplain): Rename complain, now also used in symfile.c.
3922 (push_target): Push targets within strata. New return value shows
3923 whether new target is on top of stack or not. Always keep dummy
3925 (target_files_info): Ignore dummy target.
3927 * core.c (core_open): Warn user, and skip accessing file, if the
3928 core target is not the topmost target in the stack.
3929 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
3932 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
3933 target_ops, it doesn't belong there since we have no regs there.
3934 Change name of target from machine => memory to clarify.
3936 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
3938 * Freeze version 3.93 for release.
3940 * Makefile.dist: Handle vx-share and nindy-share subdirs
3941 properly when building gdb.tar.Z.
3943 * symtab.c: lint; add no_symtab_msg to consolidate the messages
3944 printed in various places, so I could change just one copy.
3946 * dbxread.c, coffread.c: Change references to bfd->iostream
3947 to cast to FILE *, now that BFD avoids needing types defined
3948 in other header files.
3950 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3952 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
3953 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
3954 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
3955 (actually gcc -Wall).
3957 * dbxread.c: Remove first_global_sym, last_global_sym, since
3958 they are never referenced.
3960 * defs.h (baud_rate): Declare.
3961 main.c: Define it, and add the -b option to set it.
3963 * gdb-int.texinfo: Add text on how to define a new host or target
3964 architecture, prompted by Per Bothner's questions about MIPS
3967 * gdb.texinfo: Document "complaints". Change doc of -q since
3968 gdb no longer prints the copyright and blurb if you specify a file
3969 name to be debugged (just like Emacs). Add doc for Nindy-specific
3970 command line flags for specifying target serial port and such.
3971 Update copyright to 1991.
3973 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
3974 has taken over for us the job of ripping up executable files. The
3975 crud caused Per Bothner's port to not compile.
3977 * infrun.c (normal_stop): Avoid printing "Program exited
3978 normally" if we are in batch mode. This allows a GDB which
3979 executes a program on a target system, to behave like a Unix
3980 command (input from stdin, output to stdout, no extraneous
3983 * main.c (main): Allow additional machine-dependent command line
3984 options to be specified with the ADDITIONAL_OPTIONS,
3985 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
3986 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
3987 processing to occur just before the main loop with
3988 BEFORE_MAIN_LOOP_HOOK.
3989 (main): If a "core file" argument is specified, and it is not a
3990 core file, try it as a process ID to attach.
3991 (symbol_completion_function): Attempt to cope with
3992 "show screen-" TAB, not very successfully. This needs more work,
3994 (batch_file): New function, returns whether we are reading
3995 commands from an interactive tty on stdin, or from somewhere else.
3996 Called by normal_stop since it doesn't get from_tty passed down
3997 to it like many commands do.
3999 * remote-nindy.c: Handle command line options for nindy
4001 (nindy_before_main_loop): Prompt user for tty name if they
4002 don't specify it before getting to the interactive command loop.
4004 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
4005 and -r command line options. Also add hook before main loop
4006 to make it easy to specify a tty.
4008 * TODO: More things to do, one done.
4010 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
4012 * dbxread.c: Make complaint() calls pass pointer, not struct.
4013 Add complaints about badly formatted C++ type information
4014 (const/volatile indicator, and parse errors resulting in
4015 error_type). Fix C++ virtual member fn comment.
4016 (read_struct_type): Avoid bumping pointer if we got a parse
4017 error; this prevents our walking beyond the end of a string.
4018 Terminate loop on null char as well as semicolon.
4019 (process_one_symbol): Fix the LBRAC fix so that it uses the
4020 last previous SLINE, FUN, or SO record's PC address. C++ debug
4021 symbols did not have SLINE records in a useful order compared
4022 to the LBRAC records.
4023 (define_symbol): Handle "catch" records.
4025 * symtab.c (check_stub_type): Added new complain
4026 `stub_noname_complain' and added a consistency check to
4027 keep the debugger from crashing when finishing from an
4028 exception frame. A real fix will be needed later.
4030 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
4032 * infcmd.c (attach_command): Make global.
4034 * Makefile.dist (REMOTE_OBS): Make these compile by default,
4035 but make them easy to comment out. Perhaps later they should
4036 be enabled by what CPU you configure for? FIXME.
4037 (VERSION): Roll to 3.93.
4038 (pinsn.o): Remove rule for obsolete file.
4039 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
4041 Run down a problem that manifested by printing the wrong function
4042 name in stack traces of read_ofile_symtab. Turned out that the
4043 problem was the SunOS 4.1.1 (and previous) C compiler outputs
4044 the LBRAC symbol with an address in the *data* segment, which
4045 blew our binary search through the blocks.
4047 * dbxread.c: Use the complain() facility consistently to bitch
4048 about problems in the symbol file we are reading.
4049 (finish_block): Add code to check the nesting of the blocks;
4050 complain and Procrust them to fit if wrong.
4051 (make_blockvector): Check the order of the blocks, complain
4052 [but don't cope] if wrong.
4053 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
4054 symbols to be sure their PC value is greater than the last SLINE
4055 (line number) symbol we've seen, complaining and adopting the
4056 SLINE PC value if wrong.
4058 * symfile.h (struct complaint, complaint_root, complain,
4059 clear_complaints): Add.
4060 * symfile.c (complain, complaint_root, clear_complaints): Add
4061 facility to deal with non-fatal complaints and to regularize their
4063 (symbol_file_add): Clear complaint counters to allow new complaints.
4064 (initialize_symfile): Add 'set complaints' and 'show complaints'.
4066 * dbxread.c (dbx_symfile_read): Remember the address and size
4067 of the string table for the main symbol file, so we won't read it
4069 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
4070 to avoid reading the string table yet again. Lint.
4071 (throughout): Improve filtered output, including word wrap.
4072 (read_range_type): Improve Bothner's fix to handle other types too.
4074 * utils.c: Improve line wrap implementation. Handle unlimited
4075 width by making chars_per_line unsigned.
4076 (puts_filtered): New, easy, function.
4078 * defs.h (puts_filtered): add.
4080 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
4081 call the identical sort_symtab_syms() in symfile.c instead.
4083 * expread.y: Suggest the `file' command rather than `symbol-file'.
4085 * command.h (enum var_types): Add zinteger for seroable
4087 * command.c (do_setshow_command): Handle var_zinteger. Restructure
4088 nested if's into a switch.
4090 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
4091 we did not stop because of a breakpoint (it must have been for
4092 some other reason, like a "stepi"), so don't print anything.
4094 * symtab.c: Include <sys/types.h> all the time. Now that BFD
4095 doesn't include <sys/types.h>, old SunOS's require it for
4098 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
4100 A test port of gdb-3.92.6 to the Sony NEWS.
4103 Don't normally link in remote- or vx stuff.
4104 Some of it doesn't compile, and it wastes space for 99% of the users.
4105 Remove reference to no-longer-used HAVE_VPRINTF.
4106 Fixed BFD_DEP typo to BFD_DIR.
4108 Fix cast in arg to bfd_h_getlong.
4109 Make char *prefix be const.
4110 Fix how certain range types are mapped into builtin unsigned int types.
4112 Remove 2 #includes. They cause errors (on Sony, at least),
4113 and aren't needed (they wern't in earlier versions).
4115 print_address_symbolic should never demangle labels
4116 (since it prints *assembler-level* labels).
4118 [This was superseded by the change to printcmd below.]
4121 Add some "volatile" return types to avoid warnings.
4122 If MISSING_VPRINTF add vprintf function and not just macro
4123 (since vprintf is used in printcmd.c).
4125 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
4126 (The latter isn't grokked by some PCC-based compilers.)
4128 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
4130 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
4131 * nindy-share/coffstrip.c
4132 Added some forward declarations (otherwise, gcc complains
4133 about implicit extern redefined as static).
4135 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
4137 Changes inspired by Per Bothner:
4138 * printcmd.c (print_address_symbolic): Take additional parameter
4139 specifying whether to demangle.
4140 (print_address): Pass in asm_demangle to control demangling.
4141 (print_address_demangle): New fn, takes explicit arg to control
4143 * utils.c: Add new vars demangle and asm_demangle, and let them
4145 (fputs_demangled): If !demangle, just print the argument.
4146 (fprint_symbol): If !demangle, just print raw symbol.
4147 * valprint.c (val_print): Call print_address_demangle rather than
4148 print_address, to cause demangling to depend on the global
4149 rather than assembler-level demangling setting.
4150 * WHATS.NEW, gdb.texinfo: Document.
4152 * main.c (show_command): Show all settings if no arg.
4153 (initialize_main): Make "info set" the same as naked "show".
4154 * command.c (cmd_show_list): Handle prefix commands in the
4155 list, and print the name of the setting as well as its English
4156 description and value.
4158 Allow gdb functions to specify where a line should wrap if it
4159 exceeds the size of a terminal line. Use it to make the output
4161 * utils.c (set_screen_width_command): New fn, mallocs a buffer
4162 of the right size when screen width changes.
4163 (set_screensize_command, screensize_info): Remove #if 0'd fns.
4164 (wrap_here): New fn, indicates a point in the output where we
4165 should wrap the line rather than just letting it overflow at a
4167 (fputs_filtered): Implement wrapping.
4168 (n_spaces): New fn, returns a pointer to N spaces.
4169 (print_spaces_filtered): Use n_spaces.
4170 * defs.h (n_spaces): Declare.
4171 * stack.c (print_frame_info): Wrap with 4-space indent after
4172 fn name and before filename and line number.
4173 * printcmd.c (print_frame_args): Wrap with 4-space indent
4174 before each argument name is printed.
4175 * valprint.c (value_print): Wrap with no indentation before
4177 (val_print_fields): Wrap with indentation relative to nesting
4178 level before each field name.
4179 (val_print): Wrap with nesting indentation before array elements.
4180 * command.c (do_setshow_command): Avoid extra newlines,
4181 wrap with 4-space indent around values printed, end with period.
4182 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
4184 * breakpoint.c (breakpoint_1): Implement addressprint for
4185 "info breakpoints" display. Change file name and line number
4186 format to " at file:nnn" rather than " (file line nnn)".
4187 * gdb.texinfo: Document.
4190 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4192 Frozen for gdb-3.92.6 release.
4194 README, WHATS.NEW: Update for 3.92.6 release.
4196 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
4197 coffread.o from configs since it is now built by default.
4198 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
4199 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
4200 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
4201 from configs since it is now built by default.
4203 Makefile.dist: Update for release 3.92.6. Handle files that
4204 have been moved to ../include, ../getopt, or ../bfd. Add
4205 saber.suppress and tests directory. Add config.status to
4206 the release (it will say "none").
4208 coredep.c: Minor formatting fixes.
4210 These changes were made in early December but only checked in now:
4211 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
4212 nindy-share/nindy.c: lint
4213 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
4214 register values coming back from the target; we store values
4215 in target byte order everywhere.
4217 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
4219 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
4221 * valprint.c (cplus_val_print, val_print_fields): New functions,
4222 which print C++ objects. They conspire to avoid printing a
4223 virtual base class more than once, following all the twists and
4224 turns of C++ virtual base rules.
4225 (val_print): Call the above rather than do it by hand.
4227 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
4228 symbol file, not for added files like shared libs. This really
4229 needs to be generalized to a timestamp per file.
4231 * core.c (cleanup_core): Avoid coredump if no core file.
4233 * config.gdb: Accept -host or -target in place of +host or
4236 * coffread.c (find_linenos): Avoid desupported BFD interface
4237 to line numbers. We still read them manually rather than using
4238 BFD's "generic" features.
4240 * gdbrc.tex, threecol.tex: Add GDB reference card and its
4242 Makefile.dist: Add refcard to OTHERS list for creating tar files.
4244 * Makefile.dist: Eliminate use of $< in explicit targets.
4246 * readline/Makefile: Use $< rather than $*.c, which does not
4247 include the VPATH in GNU Make.
4249 * tconfig/i960-bout, tconfig/i960-coff: These are identical
4250 copies of tconfig/i960, added for global configuration
4251 compatability. All i960 versions can read both coff and b.out.
4253 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
4254 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
4257 * TODO: Think of more things to do.
4259 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
4261 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
4262 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
4263 64-bit float conversion.
4265 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
4266 equivalent to sun?os4 so global config works.
4268 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
4270 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
4272 * main.c: Only declare linesize once; declare pagesize not at
4273 all, since it is never used.
4274 (main): Clear newly allocated line before it is used.
4276 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
4278 Further stabilization for the Intel 960.
4280 * Makefile.dist: Parameterize the location of the "include"
4281 and "bfd" directories, as well as "getopt". Add symfile.c.
4282 Link in both dbxread and coffread. Fix up "make depend" to
4283 rewack the locations of include, bfd, and getopt in its output.
4285 * README: Document moving include files, improve some of
4288 * coffread.c: Move common code out to symfile.c. Change
4289 symbol_file_command style interface to use new *_symfile_init
4290 and *_symfile_read interface under BFD. Use BFD internal
4291 info to locate line table, symbols, etc.
4293 * core.c (core_fetch_registers): Rename to get_core_registers
4294 to avoid confusion with fetch_core_registers.
4295 (register_addr): Move to coredep.c, which is already machine
4296 dependent. This leaves core.c pretty clean of dependencies.
4298 * coredep.c (register_addr): Accept this routine from core.c.
4300 * dbxread.c: Move common code (with coffread.c, etc) into new
4301 symfile.c. Each psymtab now contains a pointer to the
4302 format-dependent function that knows how to read it in. Make
4304 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
4305 (process_one_symbol): Add code to complain about a "compiler bug
4306 we muzzle here", if we actually see it.
4308 * eval.c (evaluate_subexp): Insert missing "break" statements
4309 in code that determines whether a variable is an lvalue in
4310 memory, register, or whatever. I detected this via a compiler
4311 bug in which it *almost* mashed out the whole switch statement.
4313 * gdb-int.texinfo: Add minor sections on configuring gdb for
4314 release, and about the README file.
4316 * infcmd.c (registers_info): Fix formatting somewhat. Still
4317 not as pretty as before, but it handles byte swapping.
4319 * remote-nindy.c: If data cache routines are interrupted while
4320 waiting for the remote end, be sure that any uninitialized cache
4321 blocks are on the free list, not on the valid list!
4323 * symfile.h: Flesh out this header file with all the various
4324 routines and variables that have been merged in from dbxread.c
4325 coffread.c, and symtab.c to symfile.c.
4327 * symfile.c: New file, containing code common to dbxread.c,
4328 coffread.c, and some code from symtab.c. All generic code for
4329 reading symbol files should be in here now.
4330 (unrecord_misc_function): Remove unused function.
4332 * symtab.h: Remove file-reading things to symfile.h.
4334 * symtab.c: Remove file-reading things to symfile.c.
4336 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
4337 to decode i960 fault types.
4339 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
4340 target.c: Change type of the "resume" function from int to void,
4341 since its result was never used.
4343 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
4345 * main.c: Replace "stupid" with "caution"; you now "set caution
4348 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
4350 * infcmd.c (do_registers_info): Call val_print to deal with the
4351 byte order of the registers being printed. FIXME, this makes
4352 the formatting of the output uglier.
4354 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
4355 defined, call it for signals the debugger doesn't itself use.
4356 The i960 uses this for more detailed fault information.
4358 * remote.c (remote_open): If arg is null, print help rather than
4361 * sparc-xdep.c (register_valid): Avoid declaring size, since
4362 various modules will think of various sizes depending on the
4363 architecture of their tm-file. FIXME, we need protection against
4364 actually entering one of those modules, which would clobber
4365 storage if not for the target architecture compiled into gdb.
4367 * stack.c (up_command, down_command): Always print the frame
4369 (up_silently_command, down_silently_command): New commands
4372 * i960-pinsn.c (reg), i960-tdep.c: Lint.
4374 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
4375 more parameters than it used to.
4377 * findvar.c (registers): Increase slop to 256 bytes, which should
4378 protect us against even most RISC machines with large register
4380 (locate_var_value): Move declaration inside related ifdef.
4382 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
4383 throughout, to avoid throwing away buffered input from the board.
4384 (nindy_wait): Supply_register takes addr_of_value, not value.
4385 (i960_print_fault): Renamed from i80960_fault.
4386 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
4387 (nindy_store_registers): Avoid regs_changed stuff, just stuff
4389 (nindy_create_inferior): Don't bother to write PC_REGNUM since
4390 we can set the PC in the call to proceed(). Unpush nindy_ops
4391 before pushing it on top, to avoid message to user. Eliminate
4392 commentary from Unix machines that just misleads here.
4393 (reset_command): Fix error message to suggest target command.
4395 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
4397 Release 3.92.5 as frozen.
4399 Stabilize the merged release...with help from lint, Saber C,
4402 Everywhere: Add include files needed to declare return types
4403 of functions called.
4405 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
4407 * breakpoint.h: Add undeclared breakpoint functions, and some
4408 functions for display handling since I couldn't think of a better
4411 * breakpoint.c (insert_breakpoints): Make code for disabling
4412 shared library bkpts more likely to work. It's used when we
4413 rerun a program and stop before the shared library has been
4415 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
4416 cast from pointer, so it squeezes through catch_errors.
4417 (bpstat_stop_status): Fix logic broken some time ago. We now
4418 always create a bpstat if the stop address matches a breakpoint,
4419 even if we don't stop there -- just like the old code used to do
4420 before I got my fingers into it (sigh).
4421 (breakpoint_1): Print "ignore count" after "stop only if"
4422 condition, since that's how it actually works.
4423 (mention): Handle watchpoints as well as breakpoints.
4424 (watch_command): use set_raw_breakpoint and mention to do most
4425 of the work (and initialize all the fields!). Only pass one
4426 arg to parse_c_expression, since that's all it takes.
4428 * command.c (not_just_help_class_command): Rename arg to args
4429 since we ignore "unused argument" warnings on vars named "args".
4430 inflow.c (child_terminal_info): ditto.
4431 infptrace.c (kill_inferior): ditto
4432 main.c (catch_errors, version_info, quit_command, pwd_command,
4433 source_command, dump_me_command, editing_info,
4434 set_history_size_command, set_history, show_history,
4436 stack.c (locals_info): ditto
4437 target.c (target_files_info): ditto
4438 valprint.c (set_input_radix, set_output_radix): ditto
4440 * core.c: Remove old variables for handling core and exec file
4441 sections (data_start, data_end, stack_start, stack_end,
4442 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
4443 text_end, exec_data_start, exec_data_end, text_offset,
4444 exec_data_offset, data_offset, stack_offset). They're
4445 superseded the more general build_section_table and
4447 (get_exec_file): Mention the `file' command.
4448 (read_memory_check): Rename to memory_error, and only call it
4449 in the case of an actual error.
4450 (read_memory, write_memory): call memory_error.
4451 (core_fetch_registers): Register section name is ".reg".
4453 coredep.c: Remove a bunch of crud now that all this file does
4454 is pull the registers out of a core file.
4455 (fetch_core_registers): Rewrite to actually work, I hope.
4457 dbxread.c: Use a.out.gnu.h, not system a.out, now.
4458 Replace index() with strchr(). Remove all the pre-BFD macro
4459 definitions for accessing the symbol file.
4460 (struct dbx_symfile_info): Encapsulate the information that
4461 dbx_symfile_init needs to pass to dbx_symfile_read in this
4464 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
4465 dbx_symfile_discard): Rearrange symbol file reading to divide
4466 the format-specific part from the format-independent part,
4467 leaving the format-independent part such as file name expansion
4468 and opening in symtab.c. This replaces
4469 partial_symbol_file_open and partial_symbol_file_read.
4470 Symbol_file_read, add_file, add_file_target_command,
4471 add_file_addr_command move to symtab.c. Pass an explicit
4472 "mainline" flag for when reading the main symbol table, rather
4473 than relying on the offset address to be zero or nonzero.
4475 (dbx_symfile_read): Don't allow void *'s to be printed as
4477 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
4478 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
4479 macro" debug version really work.
4480 (read_dbx_symtab): Remove unref'd parameter inclink.
4481 Avoid swapping N_SLINE symbols, for speed.
4482 Merge N_TEXT!N_EXT case with the other external symbol
4483 definitions' case. Add comments.
4484 (start_psymtab): Allocate the symfile name in the psymtab on
4485 the psymbol_obstack, rather than using the caller's storage.
4486 (end_psymtab): Only allocate a dependencies list if there are
4488 (psymtab_to_symtab_2): Use BFD when reopening file to read
4489 its symbols for real.
4490 (read_struct_type): Add FIXME comments where it needs work
4492 (read_huge_number): Add FIXME about overflows.
4493 (read_range_type): Add FIXME about comparing a long to 1<<32.
4495 * coffread.c: Minor changes to move things closer to the new
4496 regime with symtab.c and dbxread.c Major work is still needed
4499 * exec.c (exec_file_command): Remove old variables (see core.c
4501 (xfer_memory): If memory transfer is right at the end of a
4502 section, don't lose.
4504 * findvar.c (get_saved_register): If value is in a real
4505 register, LVAL is lval_register, not lval_memory.
4507 frame.h: Declare print_sel_frame and record_selected_frame.
4509 gdb-int.texinfo: New file, for GDB internals documentation.
4510 Very simple, unformatted doc of cleanups is there for now.
4512 gdbcore.h: Remove obsolete variables that described a.out
4513 section addresses and offsets. (See core.c above.)
4514 Declare fetch_core_registers and registers_fetched.
4516 getopt.c: Declare char *alloca(); even on SPARC.
4518 infcmd.c (run_command): Call target_kill rather than
4520 (step_command, next_command, stepi_command, nexti_command):
4521 Declare from_tty parameter even though we don't use it.
4522 (run_stack_dummy): argument BUFFER is a char array, not
4523 a pointer to REGISTER_TYPE.
4524 (finish_command): using_struct_return needed a value *,
4525 not a struct symbol *.
4527 * infptrace.c (child_xfer_memory): To avoid dependency on
4528 where sections are in memory, try PT_WRITE_D and if that fails,
4529 try PT_WRITE_I. Most Unixes don't care which you use.
4531 * infrun.c (step_resume_break_shadow): Change to array to
4532 match other breakpoint shadow storage.
4533 (clear_proceed_status): Pass address of bpstat to
4534 bpstat_clear, not the bpstat itself.
4535 (child_create_inferior): FIXME comment about if the child
4537 (start_inferior): Remove old function.
4538 (child_open): Use target_kill rather than kill_inferior.
4539 (wait_for_inferior): Ditto.
4540 (insert_step_breakpoint, remote_step_breakpoint): Use
4541 new step_resume_break_shadow.
4543 * inftarg.c (child_wait): If all child processes die,
4544 pretend that the one being waited for exited with signal 42.
4546 * main.c (command_line_input): When scanning for comments,
4547 don't coredump on unclosed quotes.
4548 (quit_command): Use target_kill rther than kill_inferior.
4549 (_initialize_main): Rename class_user from "user" to
4552 * printcmd.c (print_command_1): Initialize "fmt" if no format
4553 is specified by the user.
4554 (print_frame_args): Only add to args_printed if we are
4555 actually fetching args from the stack (avoiding undefined
4557 (_initialize_printcmd): Remove bogus \{ from string.
4559 * remote-eb.c (eb_open): Avoid coredump on no argument.
4561 * remote-nindy.c: Bring out of Intel environment into new
4562 target environment. Remove all conditional compilation on
4563 I80960. Massive hacking throughout.
4564 (nindy_xfer_inferior_memory): New routine stolen from
4566 (nindy_create_inferior): New routine pieced together, probably
4567 not quite working yet.
4568 (nindy_ops): New target_ops struct for nindy.
4570 * remote-vx.c: Use write_memory rather than target_write_memory
4571 to get error checking.
4572 (vx_add_file_command, vx_open): Use symbol_file_add rather than
4574 (vx_create_inferior): Use target_terminal_ours...
4576 * signame.c (_initialize_signame): Always initialize, since
4577 we need the table for things other than psignal.
4579 * solib.c (solib_add): Use symbol_file_add, not add_file.
4580 (solib_address): Return boolean result rather than struct
4581 pointer which nobody else knows the type of.
4583 * sparc-tdep.c, valops.c: Use write_memory rather than
4584 target_write_memory, to get error checking.
4586 * stack.c (locals_info, catch_info, args_info,
4587 get_selected_block, frame_command, up_command): Use
4588 target_has_stack, rather than have_inferior_p or
4591 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
4593 * symfile.h: New file, defining the interface between the
4594 generic and object-file-specific symbol reading code.
4596 * symtab.c: Move generic symbol-reading interface to symtab.c,
4597 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
4598 table to map BFD targets to symbol-reading modules in GDB.
4599 Change index to strchr.
4600 (lookup_struct_elt_type): Use error() rather than hand-made
4601 simulations thereof.
4602 (lookup_partial_symbol): Speedup slightly when length == 0.
4603 (symbol_file_add): New function.
4604 (symbol_file_command): Call it.
4605 (symfile_open, symfile_init): New function.
4606 (add_file_target_command, add_file_addr_command): moved from
4609 * target.c (target_command): use target_kill.
4611 * target.h (target_files_info): Don't declare, never called
4614 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
4615 files to determine stack end address.
4617 * valarith.c (value_x_binop, value_x_unop): Change error message
4618 to be more useful. Pass proper argument to value_struct_elt.
4620 * valops.c (value_assign): FIXME comment that long long
4621 bitfields will break here.
4623 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
4624 Update `make saber_gdb' to work better.
4626 * TODO: A woman's work is never done.
4628 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
4629 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
4630 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
4631 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
4632 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
4633 valops.c, valprint.c, exec.c: Lint.
4636 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
4638 Continuing Intel 960 port merge of GDB.
4640 * Makefile.dist: Merge i960 "nindy-share" files. Rename
4641 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
4642 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
4643 Wack over "make depend" so it handles files in subdirectories
4644 vx-share, nindy-share, bfd, and in the current directory.
4646 * blockframe.c (get_prev_frame_info): Remove fatal error
4647 if stack not defined.
4649 * core.c (core_open, core_detach): New functions that handle
4650 the old "core-file" command as "target core" and "detach" instead.
4651 (core_file_command): Call them.
4652 (core_xfer_memory): Use common routine xfer_memory.
4654 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
4655 dbxread now uses bfd for everything but symbol reading itself.
4656 BFD internals are used to drag out the relevant file offsets.
4657 (partial_symbol_file_open): Change args all around for BFD.
4659 * symtab.c: Rename "value" to "val" everywhere, so we can
4661 (symbol_file_command): New command, moved from dbxread.c
4662 and coffread.c. It uses BFD to read the file, then vectors
4663 based on its type, to dbx or coff symbol readers.
4664 * symtab.h: Extern a few vars for symbol_file_command.
4666 * target.h: Breakpoint takes a char * save area, not a char **.
4668 * valprint.c (val_print): When unpacking bitfields, offset
4669 the address in gdb of the value, if it is declared with a shorter
4670 type. Remove the last "runtime kludge test" of host byte order.
4672 * utils.c: Remove old my_bfd_read routine.
4674 * stack.c (frame_info): Use target_has_stack. Print program counter
4675 register's actual name rather than "pc", since it's called the
4676 "ip" (instruction pointer) on the i960 (sigh).
4678 * target.c (target_command): Add command for selecting a target
4679 type and calling its open routine. This is used for initiating
4680 communication with a particular target, in a generic way.
4682 * tm-i960.h: Update for modern gdb. Remove semicolons from
4683 various macros. Handle reading struct return convention, and
4684 error-out attempts to return structs with the "return" command.
4685 Be sure gdb doesn't think we know how to call functions in the
4688 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
4689 to i960_xxx in lower case.
4690 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
4691 not being defined yet.
4693 * remote.c (remote_open): Call start_remote to initialize
4694 wait_for_inferior during open.
4695 (remote_xfer_inferior_memory): Return length written rather
4698 * remote-vx.c (target_command -> vx_open): Use new generic
4700 * remote-eb.c, inftarg.c, exec.c: ditto.
4702 * infrun.c: Fix comments.
4703 (attach_program -> child_open): Use new generic target command.
4704 (wait_for_inferior): Clear saved register values before target_wait,
4705 so target_wait can set some of them if convenient.
4707 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
4708 Return success indicator, not void.
4709 (child_xfer_memory): Avoid fetching initial word if we'll
4710 overwrite it anyway.
4712 * infcmd.c (attach_command): Use new generic target open routine.
4713 (_initialize_infcmd): Update doc on attach and detach commands.
4714 (do_registers_info): Merge in a byte-order problem as a FIXME
4717 * findvar.c (find_saved_register): Avoid problem in current frame.
4718 (read_relative_register): Ditto.
4719 (write_register): Convert byte order on the way out.
4721 * exec.c (file_command): Add.
4722 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
4723 (xfer_memory): Common function between core_xfer_memory and
4725 (exec_xfer_memory): Use it.
4727 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
4729 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
4730 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
4731 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
4733 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
4735 Merge Intel 960 port of gdb, continuing...
4737 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
4738 symbol_file_command): Pass from_tty arg to hush 'em up.
4740 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
4741 Add magic numbers for 960 COFF format.
4743 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
4745 Merge Intel 960 port of gdb, from Intel "1.2" release.
4747 CHANGE_LOG entries from their port, which was based on
4750 Thu Sep 6 11:02:22 PDT 1990
4751 Remove temp file if download is interrupted.
4753 Wed Aug 1 09:08:33 PDT 1990
4754 Now uses binary protocol to talk to NINDY.
4755 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
4756 Times out after 5 seconds when trying to talk to NINDY.
4758 Tue May 29 12:54:49 PDT 1990
4759 Added variable baud rate (-b switch).
4760 Source code reorganization.
4762 Thu Apr 26 11:09:55 PDT 1990
4763 More cleanup of batch mode; specifically, execute "-s", "-e", and
4764 "-se" switches as soon as they are encountered on the invocation line.
4766 Fri Apr 20 13:47:15 PDT 1990
4769 Thu Apr 19 09:54:28 PDT 1990
4770 Add 'reset' command.
4772 Wed Apr 18 09:48:07 PDT 1990
4773 After opening remote tty, wait for 1 second to go by without input
4774 from it before trying to talk to NINDY (fixes problems with the
4775 Heurikon HK80/V960E).
4777 Mon Apr 4 16:33:05 PDT 1990
4778 Some output was not being suppressed in 'batch' mode.
4780 Thu Mar 22 15:31:11 PST 1990
4781 Ask user if old symbol table should be deleted when new file is
4784 Allow user to run a program downloaded before gdb960 was brought up.
4786 Correct "exec-file" help message for i80960 context.
4788 Correct bug in calculating user space address: could occasionally
4789 corrupt user program.
4791 Make sure to zero low-order bits in rip's because of bug in 960CA
4792 A-step part: could cause operation faults when "next"ing across
4795 Correct bug that made it impossible to get source line numbers for
4796 code loaded at addresses higher than 0x7fffffff.
4798 Wed Jan 10 12:43:22 PST 1990
4799 Open remote tty for exclusive use.
4801 Fri Jan 5 12:14:42 PST 1990
4802 Correct disassembly (CA manual was right after all):
4803 opcode for sysctl is 0x659
4805 Mon Oct 23 12:03:04 PDT 1989
4806 Use G960BASE and G960BIN environment variables to find 'sx' utility.
4808 Mon Oct 16 14:15:09 PDT 1989
4809 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
4811 Mon Oct 2 15:56:31 PDT 1989
4813 Added 960CA disassembly support.
4815 To simplify maintenance:
4816 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
4818 - eliminated opcode.h: incorporates tables into i960-pinsn.c
4819 - moved 960-specific routines from i960-pinsn.c to i960-md.c
4820 - made disassembly interface identical to that in gdmp960.
4824 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
4826 * target.h: Allow targets to stack. Add target_has_memory,
4827 _registers, etc. Restructure memory access and "info files"
4828 to walk the target stack.
4829 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
4830 target.c: Change tables to match target.h.
4831 * inflow.c (child_mourn_inferior): pop child_ops.
4832 (generic_mourn_inferior): Use new has_stack flag.
4833 * infptrace.c (child_xfer_memory): New memory regime.
4834 * inftarg.c (child_files_info): New "info files" regime.
4835 * remote-eb.c: New memory regime, new info files.
4836 * remote-vx.c: New memory regime, new info files. Now use
4837 separate targets for VxWorks attachment to machine, and
4838 actually running a process under VxWorks, since one has
4839 stack & execution & regs and the other doesn't.
4840 * remote.c: New memory regime, new info files.
4841 * sparc-xdep.c (fetch_core-registers): New memory regime.
4842 * target.c: New routines and support for stacked targets,
4843 new memory regime, new info files regime.
4846 Generalize section handling for an arbitrary number of sections,
4847 including use of the new BFD (binary file) library.
4848 * gdbcore.h: Add struct section_table.
4849 * exec.c (build_section_table): Iterate all sections and
4850 record what gdb needs to know about them.
4851 (exec_command): Use it.
4852 (exec_xfer_memory): Use the table.
4853 (exec_files_info): Print the table.
4854 * core.c (core_file_command, core_xfer_memory, core_files_info):
4856 * source.c (find_source_lines): Use bfd_get_mtime.
4857 * dbxread.c: Quick changes to make it compile with new BFD.
4858 * utils.c (error): Avoid using bfd_error in generic routines.
4860 * core.c (core_fetch_registers): Get from the ".regs" section of
4862 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
4864 * inferior.h (attach_flag): Export.
4865 * infcmd.c (run_command): use new target_create_inferior.
4866 * infrun.c (child_create_inferior): Don't return result.
4867 * Makefile.dist (VERSION): 3.91.4.
4869 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
4871 * breakpoint.c (bpstat_num): Handle breakpoints which have
4872 since been deleted, such as temporary breakpoints.
4873 infcmd.c (program_info): ditto.
4875 * core.c (core_file_command): Display the frame where the core
4880 * remote-vx.c (target_command): Merge in target command from
4881 targ-vx.c. A few other cleanups.
4883 * TODO, Projects: Lots more stuff to do...
4885 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
4887 Massive changes to wall off the remote-debugging interface
4888 behind a function vector. The port to handle VxWorks targets
4889 is also part of this.
4891 All files: Replace references to renamed functions,
4892 remove references to remote_debugging, remove references to
4893 have_include_file, have_core_file in favor of target_has_stack,
4894 target_has_memory, etc.
4896 * Modularize the breakpoint interface.
4897 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
4898 a breakpoint instruction.
4899 breakpoint.c: struct breakpoint's shadow_contents now sized as
4901 (insert_breakpoints): Vector to target to install breakpoints.
4902 (remove_breakpoints): Vector to target here too.
4903 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
4904 sparc-tdep.c (single_step): Use new breakpoint interface for
4905 the single-step breakpoints.
4906 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
4907 New file, contains routines to insert and remove breakpoints by
4908 reading out the old contents and later replacing them. This is
4909 how ptrace breakpoints work, and many remote systems as well.
4911 * tm-vxworks68.h: New config file, overrides a few things for
4912 Wind River's preferences.
4914 * target.h: New file, for transfer vector used to talk to the
4915 inferior (child, attached, core, exec, remote, etc). All accesses
4916 to the thing being debugged should come through these vectors.
4917 target.c: New file, routines to handle transfer vector.
4918 (various files): Add transfer vectors XXX_ops for the various
4919 targets and pseudo-targets (core files, etc) we support.
4921 * breakpoint.c (bpstat_stop_status): Further explorations of
4922 watchpoints and why things don't work all the time.
4923 (bpstat_alloc): New fn to allocate a bpstat and chain it.
4925 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
4926 the local gdbinit if it doesn't already have it.
4928 * core.c (core_ops): add and install.
4929 Allow core debugging without exec file.
4931 * dbxread.c (free_and_init_header_files): Merge two fns.
4932 (end_symtab): Free named symbol table when a new version comes in.
4933 (read_dbx_symtab): Relocate all kinds of symbols with base
4934 address. First step toward handling different text, data, bss
4936 (add_file_addr_command): Renamed add_file_command.
4937 (add_file_command): Vector to remote handler.
4938 Add "load" as an alias for "add-file" command.
4940 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
4941 non-returning functions.
4943 * exec.c: Add exec_ops, and push it as a target when an exec
4946 * infcmd.c (run_command): Pass executable file name and arg list
4947 separately when starting an inferior. Permit "run" when no exec
4948 file is specified, for VxWorks.
4949 (detach_command): Move to child_detach in inftarg.c.
4951 * inftarg.c: New file. Unix-child-specific routines, and the
4952 child_ops structure.
4954 * inferior.h (registers): Export "registers" as the way for
4955 target dependent register handlers to find gdb's local copy of
4956 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
4957 since it is now used by places that want wait_for_inferior to
4958 handle the grunge but want to see every trap from the inferior.
4960 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
4961 Eliminate remote_debugging hooks in terminal handling.
4963 * infrun.c: Replace start_inferior with child_create_inferior.
4964 Move all the hair of Unix shells and ptrace idiosyncracies into
4965 child_create_inferior, so remote handlers don't have to deal.
4966 Remove running_in_shell. Rename stop_after_attach to
4967 stop_soon_quietly, and use it in a few other places where we want
4968 to just call wait_for_inferior and get control back on the first
4969 trap. trap_expected now never takes a value > 1.
4970 (init_wait_for_inferior): Initialize static vars when a new
4973 main.c (gdbinit): Add new hook for .gdbinit file name, let
4974 it be overridden by config files as GDBINIT_FILENAME.
4975 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
4976 Both of these are used for VxWorks gdb.
4978 mcheck.c: rename include file "gmalloc.c" to avoid problems
4979 with system include file "malloc.c".
4981 param-no-tm.h: New include file, same as param.h but does not
4982 include the default "tm.h" file. This is used in files where
4983 the target is known, e.g. remote-eb.c or sparc-xdep.c.
4985 param.h: Now just a shell that includes tm.h and param-no-tm.h.
4987 remote-vx.c: New file, VxWorks remote debugging support. Uses
4988 RPC routines that are shared with the target system, in directory
4991 remote.c: Vectorize remote interface.
4993 source.c: Globalize source_path, and make an alias "l" for "list"
4994 since we now have the "load" command.
4996 sparc-xdep.c: Use new param-no-tm.h.
4998 symmisc.c (free_named_symtab): Add new function from Wind River.
4999 However, ifdef it out for now while we think about what it should
5002 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
5004 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
5005 non-Unix-children handle this with their own code in the target
5008 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
5009 source and target lists. Add vx-share to default list of include
5010 directories. Add new files to src and target lists: mem-break,
5011 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
5012 ${srcdir} versions of munch and createtags are used.
5014 * valops.c (find_function_addr): Split out of call_function.
5015 (call_function_by_hand): Rename call_function; this function
5016 calls functions in the target by laboriously patching the target
5017 word-by-word with the right stack, args, regs, etc.
5020 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
5022 Handle AMD 29000 a bit better.
5024 * remote-eb.c (readchar): Mask received char log to make it readable.
5025 (remote_start): Pass arguments down to executing program.
5026 Make startaddr unsigned.
5027 infrun.c (start_inferior): Accept args, pass them to
5029 infcmd.c (run_command): Pass args down to start_inferior.
5031 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
5032 the target object file format.
5033 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
5035 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
5036 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
5038 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
5040 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
5041 * TODO: We did a few things, we have more to do though.
5043 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
5044 * inflow.c (inferior_died): Clear deferred stores.
5046 * Debug problems with dummy frames and calls to the inferior.
5047 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
5048 * sparc-tdep.c (do_restore_insn): Simplify.
5049 (sparc_frame_find_saved_regs): Simplify and fix what we find.
5050 (sparc_push_dummy_frame): Simplify and fix what we push.
5051 (sparc_pop_frame): Slightly more hair here, deciding whether
5052 we are restoring a saved PC or returning to a return address in %i7.
5053 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
5055 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
5056 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
5057 * obstack.h (chunkfun): ditto.
5058 * defs.h (xmalloc, xrealloc): ditto
5060 * utils.c (quit): Grab the terminal from the child if necessary.
5062 * inflow.c (term_status_command): Rename to term_info, change
5065 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
5066 (is_delayed_branch): Speed up.
5067 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
5068 Still missing some float ops, and needs testing.
5070 * Support for input and output radixes other than base 10
5071 * defs.h (input_radix, output_radix): Declare.
5072 * expread.y (yyparse, parse_number): Handle changes of input
5073 radix, and ambiguous names-or-numbers in radixes >10.
5074 * printcmd.c (print_scalar_formatted): Print formatted hex
5075 numbers in varying column widths.
5076 * valprint.c (val_print): Use output_format to print scalar ints.
5077 (set_input_radix, set_output_radix, set_radix): Create.
5078 (set_output_radix): Set output_format from output_radix.
5079 (_initialize_valprint): add `set radix' but leave the others off.
5081 * main.c (execute_command): Let stupid questions be turned off.
5082 (_initialize_main): Handle "set stupidity", etc.
5084 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
5085 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
5087 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
5089 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
5090 bfd stuff is still screwed up, but with some manual work, it
5093 * breakpoint.c (bpstat_do_actions): Start over if a command
5094 proceeds the inferior, since the inferior will have stopped and
5095 will need to have its new stop-actions taken care of.
5097 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
5098 compiler fits, simplify it.
5100 * gdb.texinfo (directory command): Doc new dir command.
5101 source.c (directory_command): "dir" now puts things on the front
5102 of the path, moves dups up front, and handles multiple names
5103 on the command line, inserting each one in order. It also
5104 blows away cached line and full_filename info.
5106 * stack.c (backtrace_command): Skip "more stack frames follow"
5109 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
5110 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
5111 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
5112 The only odd one was Gould NP1, which had defined vprintf to
5115 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
5116 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
5117 variable, inspect_it.
5118 valprint.c (print_string, val_print): Use the global inspect_it
5119 to indicate whether to print in Epoch style or normal style.
5121 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
5123 * printcmd.c (call_command): add an alias for the "print" command
5124 which runs expressions and doesn't print the result if void.
5125 (print_command_1): implement it.
5127 * command.c: Remove #if 0'd code. Initialize all the fields
5128 in add_cmd (). Rename do_nothing_command to
5129 not_just_help_class_command, and make it externally visible.
5130 command.h: add user_commands to struct.
5131 * main.c (define_command): Don't overload c->function with a char
5132 string as well as a function pointer.
5134 * eval.c (evaluate_subexp): Reinstall tiemann changes to
5135 calling convention of value_struct_elt () that got dropped in
5138 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
5139 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
5141 * tm-sparc.h (POP_FRAME): replace some constants with defines.
5143 * sparc-xdep.c (store_inferior_registers): defer stores to regs
5144 until a good time (e.g. when we are about to run the child),
5145 saving ptrace calls.
5146 * infrun.c (proceed): handle DO_DEFERRED_STORES.
5147 * tm-sparc.h: define DO_DEFERRED_STORES.
5149 * sparc-xdep.c (store_inferior_registers): when storing float
5150 registers, don't store stack regs too. When storing the SP,
5151 however, DO store the stack regs too. This fixes a bug in which
5152 the dummy frame is not recognized when a call_function finishes,
5153 because its frame pointer (in the stack regs) was never
5155 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
5156 even though we don't know how to read them from an inferior.
5157 valops.c (call_function): Comment about storing SP.
5159 * infrun.c (save_inferior_status): Save away the original bpstat
5160 chain so it can be restored later. Install the copied version for
5161 use by whoever saved the status. It will be blow away by
5162 restore_inferior_status, and the original chain restored. This is
5163 important for people who have pointers into the original.
5165 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
5166 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
5167 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
5170 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
5172 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
5173 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
5174 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
5176 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
5178 * Merge Mike Tiemann's multiple inheritance changes from Sun.
5179 Store the baseclasses in a type struct starting from array element
5180 0 rather than from the unusual array element 1.
5182 dbxread.c: the above.
5183 (virtual_context): Add
5184 Read new debug information about which virtual function table
5185 a virtual function is from, and store it in fn_field.fcontext.
5187 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
5188 TYPE_FN_FIELD_STATIC_P.
5190 symtab.c: the above.
5191 valops.c: the above. Handle pointer casts of object *'s.
5192 (search_struct_method): Add.
5193 (value_struct_elt): First arg is now a pointer to a value, and is
5196 valprint.c: the above.
5197 values.c (value_virtual_fn_field): Add type arg. Handle
5198 offsetting to the proper object when calling virtual fns.
5200 (baseclass_addr): Add valuep arg.
5202 * README: Document the current state of BFD config (missing).
5203 * TODO, ChangeLog, Makefile.dist: Roll version.
5204 * WHATS.NEW: Add summary of changes since 3.5.
5206 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
5208 * dbxread.c (read_struct_type): Clear bit vectors whenever
5210 symtab.c (B_CLRALL): define.
5212 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
5213 using == rather than =. Huh... This fixes the dreaded problem
5214 wherein builtin_type_int becomes TYPE_CODE_FLT.
5216 * core.c (info_files): Show the inferior pid.
5218 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
5219 already knows how to look in the source directory.
5221 * Remove psymtab hair from many places. Remove duplicated code
5222 for searching symbol tables. Hide psymtabs from most places.
5223 Make it fast to get from a psymtab to its symtab.
5225 blockframe.c (blockvector_for_pc): Remove psymtab hair.
5226 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5227 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5228 dbxread.c: export psymtab_to_symtab, make it work if called N times.
5229 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
5230 new symtab completely. New psymtabs get symtab pointer
5231 initialized to zero. Remove MI warning printf.
5232 symtab.h: Comments. Add psymtab to symtab pointer.
5233 (PSYMTAB_TO_SYMTAB): New macro.
5234 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
5235 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
5237 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
5239 (print_frame_info): Avoid special-casing symbols that have not yet
5242 * source.c (open_source_file): Quick path if we have already
5243 located the source file by its full name.
5245 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
5246 find_pc_psymtab. When a name is found in the misc function
5247 vector, search the symbol table for its mangled name, not the
5248 name that the user typed.
5250 * bfd.h: Fix missing comment terminators, make #endifs match.
5252 * valarith.c (value_less): Handle unsigned int comparisons.
5253 Add FIXME about pointer compares, which assume host and target
5254 pointers are the same.
5256 * command.c (do_nothing_command): lint
5257 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
5258 fix comments on debug symbol format for visibility. Actually set
5259 visibility of symbols.
5260 main.c (echo_command): lint; use <readline/history.h>.
5261 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
5262 obstack.h (_obstack_blank): Rearrange pointer math to avoid
5263 pointing past end of allocated memory; saber complains.
5264 obstack.h: Declare the external functions that we use.
5265 valarith.h: use <string.h>
5266 solib.c (solib_add): lint.
5268 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
5270 * main.c (initialize_main): Default info_verbose to off, now that
5271 symbol reading is fast.
5272 (quit_command): Avoid clobbering exec_bfd while quitting.
5274 * Initial BFD (binary file diddling library) merger:
5275 coffread.c: Change AOUTHDR to struct exe_hdr.
5277 core.c: initialize initialized data at compile time.
5278 (core_file_command): Move from coredep.c, convert to bfd.
5279 (xfer_core_file): Convert to bfd.
5280 exec.c (exec_file_command): use bfd routines.
5282 mips-tdep.c: Remove exec_file_command and friends.
5285 * coredep.c: (fetch_core_registers) Convert core_file_command to
5286 fetch_core_registers.
5287 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
5289 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
5290 (my_bfd_read): More bogosity, which I don't think we call.
5291 (program_name): Remove this atrocity asap!
5293 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
5296 values.c: allocate_repeat_value was not clearing the
5297 optimized_out field.
5298 (value_static_field): minor stylistic fix (wrong macro was used).
5299 valops.c (value_struct_elt_for_address): didn't work for C++
5302 * signame.c (_initialize_signame): Initialize signal names once.
5304 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
5305 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
5306 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
5308 * remote-eb.c: Support user-settable baud rates on the serial port.
5310 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
5312 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
5314 * tconfig/sun3os4: Remove warning about native assembler,
5315 since it also occurs in the xconfig file.
5317 * findvar.c (registers): Allocate some slop after `registers'
5318 to prevent stray accesses from trashing the next variable.
5320 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
5321 on the sun-3, by changing the #ifdef from `sun3' (which is not
5322 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
5323 vars, which happened to follow `registers' in the executable.
5325 * readline/history.c (history_search): Heed gcc-2's advice
5326 and parenthesize && inside ||).
5328 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
5329 tm-29k.c: Insert FSF copyright headers.
5331 * remote-eb.c: Better comments.
5333 * Makefile.dist: Update to 3.91.6.
5334 * TODO: note PREPARE_TO_STORE problem.
5336 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
5338 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
5340 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
5342 * infrun.c (wait_for_inferior, at end): Don't set up
5343 prev_* if the inferior no longer exists.
5345 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
5346 CANNOT_EXECUTE_STACK.
5347 valops.c (call_function): Use it.
5349 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
5351 * inferior.h (PC_IN_CALL_DUMMY): New macro.
5352 infrun.c (wait_for_inferior, 2 places): Use it.
5354 * values.c (value_being_returned): Only use
5355 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
5357 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
5358 right thing for remote-eb.c.
5360 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
5361 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
5363 * blockframe.c: Put get_frame_saved_regs inside #if !defined
5364 (FRAME_FIND_SAVED_REGS).
5366 * findvar.c ({fetch,store}_registers): Check for
5367 REMOTE_{FETCH_STORE}_REGISTER macro.
5369 * findvar.c (get_saved_register): Add argument lval and
5370 change meaning of argument addr.
5371 findvar.c: Change calls to get_saved_register to reflect
5372 new calling convention.
5373 valops.c (value_assign): Use get_saved_register instead of
5374 find_saved_register.
5376 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5378 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
5379 an (uninitialized) pointer to one. Use "&" when passing it
5382 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5384 * coffread.c (getfilename): Use DGUX x_offset and x_name if
5387 * coffread.c (symbol_file_command): Put semicolon after
5389 Put safe_to_init_tdesc_context in #if defined (TDESC).
5390 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
5391 coffread.c: #include <sys/stat.h>.
5392 (read_coff_symtab): Typo: in_source_files -> in_source_file.
5393 Add missing ')' in check for "lc%" and friends. Remove
5395 Declare read_one_sym() at top of file.
5396 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
5397 MC68WRMAGIC can have the same value without causing a duplicate
5400 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
5402 * Allow a Makefile to be built without building the
5403 tm and xm file links that screw up builds in subdirectories.
5404 This is done with `config.gdb none', then you can do things
5405 like `make gdb.tar.Z'.
5406 * tconfig/none: Config file for no target system
5407 * xconfig/none: Config file for no host system
5408 * config.gdb: If no TM or XM files are called out by the
5409 host or target file, don't make links for them.
5411 * cplus-dem.c: Add documentation.
5413 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
5414 simple error, so the user's gdb doesn't crash due to some object
5415 file problem (e.g. somebody is rebuilding the file out from under
5418 * printcmd.c (print_address_symbolic): demangle the symbol.
5420 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
5421 Motorola copyrights in it. Make "make gdb.tar.Z" work.
5422 (alldeps.mak): sort and uniq all results from this; duplicates
5423 hose gdb.tar.Z link building. Remove RCS files from
5424 tconfig and xconfig. Add config files for sun386. Add
5425 a few odd files to OTHERS and HFILES.
5427 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
5429 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
5430 Roll version number to 3.91.5. Make lint work in bindir.
5432 * README: Document cross-debugging and new file structure.
5434 * blockframe.c: Lint. Include "value.h" to declare read_register.
5435 (find_pc_partial_function): remove duplicate line.
5437 * command.h: Lint. Declare error_no_arg and dont_repeat.
5439 * tm-news.h: Remove inadvertently duplicated stuff.
5441 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
5442 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
5444 * config.gdb: Allow `config.gdb host target' form. Clean
5445 up previous change that printed bogus messages when you just said
5448 * core.c: #include "command.h" for lint.
5451 * main.c: Remove some casts of enums. Lint.
5458 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
5460 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
5461 read it from memory. This will allow us to save ptrace calls
5462 eventually. Changed caller single_step too.
5464 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
5465 that we aren't going to use, saving many ptrace calls, especially
5466 when watchpointing or single stepping. Use some #define's for
5468 (store_inferior_registers): Ditto.
5469 (core_file_command): Use some #define's for constants.
5471 * tm-sparc.h: Add #define's for some register numbers, so we
5472 can eliminate the use of random constants in sparc-xdep.c.
5474 * stack.c (frame_command, print_frame_info, up_command,
5475 down_command) Remove frame_changed, since it
5476 causes a bug and doesn't seem to do anything useful. In some
5477 places it was used as a flag, in others as a stack level (?).
5479 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
5480 default is to use the portable (vprintf) version rather than the
5482 * xm-news.h (MISSING_VPRINTF): Add.
5484 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
5486 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
5488 * Remove stuff that forces -Bstatic linking of gdb, and warnings
5489 about linking debugged programs -Bstatic in the sun?os4 config
5490 files in tconfig and xconfig subdirectories.
5492 * main.c (main): Remove unreached exit(0) now that we exit
5495 * Create TODO file for online bug list. There are too many
5496 "little" bugs to keep track of on paper.
5498 * Change Projects file to refer to bug-gdb@cygnus.com
5499 rather than kingdon@ai.
5501 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
5503 * Makefile.dist (VERSION): 3.91.4 now.
5505 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
5506 (condense_misc_bunches): Add sanity check that misc_count is
5507 the same as the number of symbols in the bunch.
5509 * coffread.c: rename init_misc_bunches. Pass an argument
5510 to condense_misc_bunches (a zero).
5512 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
5513 every time we are called; don't rely on our caller to do it.
5514 (add_file): Remove call to init_misc_bunches.
5516 * mipsread.c: Only warn, don't error, if unknown symbol types.
5517 This keeps an old gdb from falling on its face if it sees newly
5518 extended symbol info. Rename init_misc_bunches.
5520 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
5522 * Merge in changes from Per Bothner for DECstations and other
5523 MIPS stuff. The rest is Bothner speaking:
5525 The next message is a merger of Alessando Forin's mips port with
5526 mine. I've tried to use my good if biased judgment to get
5527 the best of both. It *does* need testing.
5529 Some of the changes are general, *not* mips-specific.
5532 Didn't believe in little-endian bit order.
5533 There are still inconsistencies about whether flags
5534 like BITS_BIG_ENDIAN are integer (#if ...) or
5535 boolean (#ifdef ...). I tried to paper over them.
5537 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
5538 Moved some misc_function code that was common to
5539 {dbx,coff,mips}read.c to symtab.c.
5540 In the process, I think I cleaned things up a bit.
5541 At the same time, moved obsavestring and obconcat to symtab.c.
5544 Removed obsolete condense_addl_misc_bunches (use
5545 condense_misc_bunches(1) instead).
5548 Needed to include <sys/dir>, at least on DECstations.
5550 valops.c, mips-tdep.c, tm-mips.h:
5551 Added PUSH_ARGUMENTS macro to support funny argument-pushing
5552 conventions (when STACK_ALIGN is insufficient).
5553 Needed on mips, where doubles need 8-byte alignment,
5554 but ints only need 4.
5557 Removed cruft that was not being used.
5558 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
5561 Print $ before register-names (I think that makes things a little
5563 Never print two instructions, even if one delays.
5564 Removed hex-disassemble set_cmd. (This is not mips-specific,
5565 so I think the argument is whether it is generally worthwhile or not.
5566 I'm inclined to think not, given how easy it is to
5567 convert between radixes in gdb.)
5570 This is basically Alessando's code.
5571 It doesn't use obstacks; I changed it to use obstacks
5572 in a few minor places where using malloc causes a
5573 memory leak. (Probably, more places could/should be changed.)
5574 I added record_misc_function where it was missing.
5575 In symbol_file_command and add_file_command, I tried
5576 to make the code consistent with more recent versions.
5577 Minor sylistic changes in parse_procedure.
5578 Make a .gdbinfo. psuedo-symbol point back to the real
5579 procedure symbol (using the isym field).
5582 This is basically from my port, but with a lot of details
5583 and a number of routines merged in from Alessando's version.
5584 I basically used my code "raw" backtrace (use heuristics
5585 from the actual code, rather than symbol table info) - though
5586 the idea is Alessandro's. I feel my code is a little cleaner
5587 here, particularly in being a little more flexible, such as being
5588 able to handle gcc-produced code (which it now can).
5589 It also doesn't do frame caching (which is not useful
5590 more recent gdb versions).
5591 I also used my code for push_/pop_dummy, more or less.
5592 I tried to incorporate AF's code for testing sigtramp
5593 while backtracing; I probably got it wrong.
5594 Added mips_print_register, which tries to scrunch as much
5595 information as possible on a screen...
5596 Removed the skip-prologue set_cmd. As with hex-disassemble (see
5597 under mips-pinsn.c), I don't see anything mips-specific here,
5598 and I don't see it being all that useful anyway.
5601 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
5602 Use more register names (rather than hard-cases numbers).
5604 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
5606 * Hack up 3.90.11 changes:
5608 * Makefile.dist (depend): parameterize $(GCC).
5609 Add solib.c and solib.o.
5610 (readline): Fix vpath for both absolute or relative SRCDIR.
5612 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
5613 Also, let the part I didn't understand at least compile so
5614 I can test the rest. FIXME.
5616 * dbxread.c: Fix thinko using strcmp.
5617 (init_psymbol_list): declare static.
5618 (partial_symbol_file_open): Comment cleanups better, avoid
5619 cleaning up the string table since the caller will do that.
5620 Move the stat for mod time into symbol_file_command, temporarily.
5621 (There should be a mod time for each symbol file, eventually,
5622 to control its rereading. FIXME.)
5624 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
5625 SunOS, which gives error for shared libs otherwise. (From
5626 Schaefer, probably FIXME needs work for portability.)
5628 * solib.c: Move #include "param.h" to work.
5629 Lowercase all the Uppercase Letters In the Messages.
5630 (find_solib): Clean up inferior_so_name for debug printouts.
5631 Allow no argument, to mean all shared libraries.
5633 * symmisc.c: include param.h to get CLEAR_SOLIB.
5635 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
5637 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
5638 to 3.90.11. ChangeLog entries below are from this.
5640 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5644 * Makefile.dist (HFILES): Add tm-sunos.h.
5646 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5650 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
5652 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
5654 * sparc-opcode.h Added single-operand version of rett.
5656 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5658 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
5659 Put parens around gcc_p in expansion.
5661 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5663 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
5665 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5667 * Changes for Sun shared libraries:
5668 blockframe.c (find_pc_partial_function): If a non-text symbol
5669 is found, set *address = pc - FUNCTION_START_OFFSET.
5670 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
5671 Disable breakpoints instead of giving an error.
5672 source.c (select_source_symtab): Initialize cs_pst.
5673 symmisc.c: Call CLEAR_SOLIB if defined.
5674 symtab.h: Make text{low,high} CORE_ADDR not int.
5675 (psymtab): New field addr.
5677 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
5678 (record_misc_function): Give correct type for N_DATA symbols.
5679 (condense_misc_bunches): do "misc_function_count = j" regardless
5681 Take code which is shared between symbol_file_command and
5682 add_file_command and put it into partial_symbol_file_{open,read}.
5683 Split add_file_command into add_file_command and add_file.
5684 Make psymtab_to_symtab read in the string table if the file
5686 Two new parameters to read_dbx_symtab and start_psymtab.
5687 tm-sunos.h: New file.
5689 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5691 * infcmd.c: Change cont_command to continue_command and "cont"
5694 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5696 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
5698 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
5700 * values.c (USE_STRUCT_CONVENTION): Check for structures of
5701 size 1,2,4,8 rather than size < 8.
5703 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
5704 as necessary, not just once.
5706 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
5708 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5710 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
5712 * tm-news.h: Add CALL_DUMMY_*.
5714 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
5716 * config.gdb: In list_host, list_target, use ${i}, not $i.
5718 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5720 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
5722 * sparc-opcode.h: Change all store floating-point state register
5723 instructions to have the right match & lose fields.
5725 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5727 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
5729 config.gdb: If srcdir != ., create readline directory and
5730 copy a makefile into it.
5732 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
5733 consistency with POSIX.
5735 * breakpoint.c (bpstat_stop_status): Disable watchpoint
5736 when we exit its exp_valid_block.
5738 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
5740 * Makefile.dist: Bump version to 3.91.3.
5742 * Clean up handling of breakpoint commands (somewhat).
5743 Prompted by Tiemann bug report "cont 10" doesn't work any more.
5745 inferior.h: Add breakpoint_proceeded to inferior status struct
5746 and globals; save it and restore it.
5747 (clear_breakpoint_commands): Cleanup, remove old #define.
5749 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
5750 (save_inferior_status, restore_inferior_status): handle it also.
5751 (proceed): Remove earlier code that set breakpoint_proceeded.
5752 It is now set only in clear_proceed_status.
5753 (clear_proceed_status): Cleanup, use bpstat_clear rather
5754 than clear_breakpoint_commands. No callers need the stop_bpstat
5755 between clear_proceed_status and proceed.
5757 infcmd.c: Add breakpoint_proceeded definition and comment.
5758 (cont_command, jump_command, signal_command): Move call to
5759 clear_proceed_status right next to call to proceed.
5761 breakpoint.c (bpstat_do_actions): Avoid clobbering our
5762 caller's argument while running down the chain of breakpoints.
5763 Use new variable "breakpoint_proceeded" to determine when
5764 a command that it executes moves the inferior past the
5766 (bpstat_clear): Handle NULL argument.
5767 (bpstat_clear_actions): Avoid useless call to
5768 breakpoint_auto_delete.
5769 (delete_breakpoint): Clean up bpstat's that are pointing to
5770 the deleted breakpoint from the stop_bpstat chain.
5771 (breakpoint_auto_delete): Simplify.
5773 * Clean up handling of EOF, error on stdin, etc. This was
5774 prompted by a network problem that caused gdb to go into an
5775 infinite loop filling up its malloc'd memory.
5777 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
5778 not clear_breakpoints_commands, which is now gone.
5779 (main): If command_loop returns (e.g. from EOF on stdin), do
5780 a quit_command (looping back to command_loop if quit_command
5781 doesn't really quit).
5782 (command_loop): check result from command_line_input and
5783 exit if it returns NULL, rather than passing the NULL to
5785 (gdb_readline): Free malloc'd result space before returning
5788 * utils.c (query): Handle C-d to mean "yes", just as if the
5789 input was not a terminal. Also avoid infinite loop if EOF
5790 occurs in mid-input-line before newline. This allows
5791 query to be used at EOF on stdin with reasonable results.
5793 * infrun.c (proceed): Set breakpoint_proceeded.
5795 * values.c (value_as_long): Avoid infinite recursion for enums.
5796 (_initialize_values): Fix typo in help msg (kingdon).
5798 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
5799 RL_LIB for linking. This allows -lreadline for linking
5800 and nothing for dependencies, once readline is a real library.
5802 * config.gdb: Jim Kingdon: give useful error message if the
5803 host or target type is not recognized.
5805 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
5806 it just defines it. Dumb, but deal with it.
5808 * Jim Kingdon suggests:
5809 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
5811 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
5813 * Makefile.dist (VERSION): Bump version # to 3.91.2.
5815 * Clean up Bothner's changes.
5817 * blockframe.c (clear_pc_function_cache): New function.
5818 * blockframe.c: remake cache_pc_function_* static.
5819 * dbxread.c (symbol_file_command): remove references to
5820 cache_pc_function_* variables.
5821 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
5822 * printcmd.c: Avoid kludging a global variable (addressprint)
5823 to avoid printing the address of a string twice. Instead,
5824 pass the format letter 's' down low enough that it can be seen
5825 to avoid this problem.
5826 (print_formatted): Pass format arg to value_print.
5827 (restore_addressprint): Remove function.
5828 (do_examine): Avoid hacking addressprint, cleanups and such.
5829 (print_frame_args): Add a comment to a Bothner change.
5830 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
5831 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
5832 to wipe out the values cached in blockframe.c.
5833 * symtab.c (find_method): Add comment saying how big you must
5834 allocate to be "big enough". Per being terse again.
5835 * valprint.c (val_print): Handle format letter "s" to print
5836 strings without addresses. Add comment to vtbl printing code
5837 which casts with wild abandon. Rearrange reference-printing
5839 @0xaddr: value (print w/addressprint)
5840 value (print w/~addressprint)
5841 @0xaddr (parameter lists w/addressprint)
5842 or nothing (parameter lists w/o addressprint)
5844 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
5846 * Merge more changes from Per Bothner:
5848 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
5849 annoying) that I tried to improve it. Here are my suggestions.
5851 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
5854 Do automatic de-reference when taking the address of a reference.
5856 Don't deref_ref when printing parameter lists.
5858 More attempts at treating refernences properly.
5860 In val_print, if deref_ref==0, don't print dangling " = ".
5862 Add COERCE_REF macro, which de-references an REF.
5864 * Merge changes from Per Bothner:
5866 * Fixed (Sony news)-specific configuration problems.
5867 * Fixed other problems with using vanilla pcc and libc (enum problems;
5868 assumption that vsprintf exists).
5869 * Some major speed-ups (finc_pc_partial_function now caches a match;
5870 parsing avoids duplicate symbol_lookup calls).
5871 * Changed handling of baseclasses (no longer use baseclasses field
5872 of struct type, use the first n_baseclasses fields instead).
5873 * Various minor changes/fixes, most C++-related.
5876 Cache the most previous match from find_pc_partial_function.
5877 (Save both low and high ends of matching function's pc range.)
5878 This speeds up the loop of infrun.c:wait_for_inferior quite
5879 a bit, and makes step/next commands much zippier.
5881 Added an enum->int cast (otherwise, some compilers barf).
5883 No longer set baseclass offset to 0, since multiple
5884 inheritance now mostly works.
5885 Added a number of casts, to shut up compiler warnings
5886 (after stabs where made enums, not ints).
5887 When discarding a symbol table (in symbol_file_command),
5888 must clear the cache introduced in blockframe.c.
5889 Don't convert $vtbl_ptr_type to vtbl any more.
5890 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
5891 Mask off sign bit emitted by g++ for virtual table offset.
5892 Set voffset to -1 (not 1) for static member functions.
5894 Changed parsing/lexing of names to avoid doing symbol lookup twice
5895 (once when lexing to determine symbol class, once for real).
5896 Now only call symbol_lookup once. Fields of 'this' win especially big.
5898 Subpress printing addr twice in the case of 'x/s addr'.
5900 lookup_basetype_type is no longer used.
5901 Add find_methods as recursive helper function to decode_line_1.
5902 This allows multiple inheritance to work.
5903 Also, once one or more matches has been found, do not look in
5904 base-classes. (Baseclass methods would be overridden, anyway.)
5906 Removed baseclasses array in struct type.
5907 Instead of using baseclasses[i], use fields[i-1].
5908 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
5909 Changed sign convention of voffset (previous was inconsistent).
5911 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
5913 Used to assume existence of vsprintf. Re-written to not need it
5914 if HAVE_VPRINTF is undefined.
5916 typecmp was too pessimistic. Made it less so.
5918 Don't print space after address.
5919 If vtable points to a misc symbol (with 0 offset), print it,
5920 since that indicates the actual class of the object.
5921 Changed ype_print_derivation_info to use new inheritance
5922 scheme (without baseclasses vector).
5924 In value_primitive_field, fixed some bugs left over from previous set of fixes.
5925 Also, changes needed because TYPE_BASECLASSES were removed.
5927 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
5929 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
5932 If there is no path set, and the symbols don't indicate what directory
5933 a file was compiled in, look in the current directory. But either
5934 a path or a known compilation directory will prevent this.
5937 Three independent bug fixes:
5938 * Remove the #if 0 block that breaks some stuff.
5939 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
5940 adapt gdb to either SunOS 4.0.* or 4.1.
5941 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
5944 Instantiate the class T when looking for methods in it. (Tiemann@sun)
5947 (type_print) Demangle the name being printed.
5948 (type_print_base) Handle botched demangling without coredump (tiemann).
5951 (check_stub_method): Document routine.
5952 (tiemann) fix bug for no-arg functions
5953 Avoid clobbering beyond end of malloc'd storage.
5954 Terminate the argument list properly.
5956 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
5958 * Changes merged by John Gilmore:
5961 In breakpoint_1, use new print_address_symbolic instead
5962 of find_pc_partial_function. (This forces use of assembler-level
5963 addresses, and avoids misleading non-mangled source-level names.)
5965 Generalize ansi argument such that -1 means skip arglist totally.
5966 Removed global variable print_ansi_qualifiers (which made
5967 code non-reentrant), in favor of extra explicit arguments
5968 to internal routines.
5970 Add new helper function print_address_symbolic.
5971 Use find_pc_misc_function instead of find_pc_partial_function
5972 (since we want assembler-level symbols here).
5974 Print unknown function as just "f (...)", not "f (...) (...)".
5975 Use new fputs_demangled explicitly.
5977 Fixed a typing violation (problem: value.h cannot be imported
5978 without renaming many variable in this file).
5979 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
5980 decode_line_1: Moved forward some never-reached code.
5981 Made decode_line_2 skip function prologues correctly.
5983 fputs_filtered should not demangle by default.
5984 Add new fputs_demangled to demangle on demand..
5986 Change value_struct_elt to use value_primitive_field (using recursive
5987 utility function search_struct_field). This allows foo.bar to work
5988 for multiple inheritance (so far only for data fields).
5989 Change check_field in the same way (recursive helper function
5990 to support multiple inheritance).
5991 (Note: there are more of these problems that I haven't fixed.
5992 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
5993 value_of_this: 'this' symbol name is now just "this", note "$this".
5995 Don't print static members.
5996 Avoid printing "members of <type>" if there are none.
5997 Simplified type_print_derivation_info by merging duplicate code.
5998 Remove useless blank lines in type_print_base (ptype command).
6000 Added declaration of new routine value_primitive_field.
6002 Added value_primitive_field which is generalized version of
6003 value_field that can handle multiple inheritance (non-zero offsets etc).
6004 Re-implemented value_field to call value_primitive_field.
6006 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
6008 * infcmd.c -- insert else to avoid 'delete env' coredump when you
6009 delete the whole environment. Karl Berry reported the bug.
6010 * source.c - fix openp to avoid //'s in filenames, which
6011 trigger an Emacs bug causing it to not be able to find files
6012 when running gdb in a window.
6013 * dbxread.c - zap the #if 0 that botches the add-file code.
6014 It seems to work a lot better without all the code commented out.
6016 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
6018 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
6021 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
6023 * Makefile - added a ${CFLAGS} to a couple of entries,
6024 added remote-sa.sparc.c
6025 * added remote.sa-sparc.c, a modification of remote.c
6026 which conducts a dialog directly with the SparcStation prom.
6027 * breakpoint.c, infrun.c, sparcdep.c added
6028 remote_insert_breakpoint(), and remote_remove_breakpoint()
6029 to breakpoint.c instead of directly writing breakpoint instructions.
6030 * sparcdep.c on remote_debugging,there is no need
6031 to remove signle step breakpoint instructions.
6032 * main.c added "-epoch" flag and "int epoch_interface" to main.c
6034 * printcmd.c - epoch interface sends lisp expressions to open up
6035 epoch windows on inspection.
6036 * valprint.c - added arrayprint, and addressprint and made adding
6037 format controls easier
6038 * wait.h added a couple of undef's because we were getting
6039 complaints about WSTOPSIG and WTERMSIG begin redefined.

6109 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
6110 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
6111 when printing the type.

6135 step_resume_break_address != NULL, even if another_trap.
6136 If trap_expected and we enter sigtramp, then set up a
6138 If trap_expected is set when we hit the step_resume_break,
