5 that were read in from that binary file.
7 * symfile.h: Add struct objfile. Add pointer to the objfile
8 into the struct sym_fns.
9 Replace global `symfile' and `symfile_mtime' with
10 `symfile_objfile'. Add global object_files chain.

30 (fill_symbuf, SWAP_SYMBOL): Take bfd as arg.
31 (read_dbx_symtab): Just wipe out new symbols, not all, on error.
32 (end_psymtab): Blow away psymtab if empty.
33 (process_symbol_pair): Swallow into read_ofile_symtab.

39 (dbx_alloc_type): Check file number, not sym number, for -1.
40 (find_symbol_in_list): Add for xcoffread.
41 (start_symtab): Default typevector is empty. Keep reusing same

58 * dwarfread.c (scan_compilation_units, start_psymtab,
59 process_dies, end_symtab, dwarf_build_psymtabs,
60 read_lexical_block_scope, read_func_scope, read_file_scope): Take
61 and use objfile argument.
62 (psymtab_to_symtab_1, read_ofile_symtab): Don't take or use file
63 descriptor. Use BFD internal functions instead.
64 (end_symtab): Call global allocate_symtab.

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

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

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

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

765 (read_dbx_symtab, case N_DEFD): Ignore.
766 (read_enum_type): Recognize FALSE/TRUE enum as Modula-2 BOOLEAN.
767 (read_range_type): Rename MAX_OF_TYPE to MAX_OF_C_TYPE, etc.
768 #if 0 out its uses, though, since they set a dead value.
769 * coffread.c (end_symtab): Use allocate_symtab.
770 (process_coff_symbol): #if 0'd for functions and params as above.
771 (read_enum_type): Recognize Modula-2 BOOLEAN.
772 * symtab.c (add_param_to_type): #if 0'd function to add a
773 parameter type to a function type's field list.

844 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
846 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
847 entries are enclosed herein. Not all of these changes
848 have been merged into the master GDB sources -- check the
849 ChangeLog above here for the merge log.
851 Mon Jun 3 17:05:45 EDT 1991
853 m2-exp.y Created. Tested outside of GDB for a few days. Proper
854 operators were added, C specific operators and tokens
855 removed. yylex() revamped to some extent. Still things
856 missing from the grammar, such as sets.
857 Tested for two weeks in GDB v3.5.
859 Tue Jun 11 17:23:48 EDT 1991
861 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
862 so they are built-in. Sort of a hack.
864 Fri Jun 14 12:53:51 EDT 1991
866 m2-exp.y Added range checking for numeric constants. Any numeric
867 constant is assumed to be of builtin type INTEGER unless:
868 (1) it is octal or hexadecimal, in which case it is a
869 CARDINAL; (2) it is too big to fit into an INTEGER, in
870 which case it is a CARDINAL.
871 eval.c Added simple range checking for +, -, and * on integers.
872 Doesn't work very well for *, since 6 * 1,000,000,000 =
873 1,705,032,704, which fails the simple test of result >=
874 first_operand, no matter in what order the operands are.
876 Tue Jun 18 14:11:30 EDT 1991
878 Broke the parser into parts, one containing the C grammar and the other
879 containing code to be shared by all of the grammars.
881 The following files no longer exist:
886 The following files were added:
888 c-exp.y (The C grammar)
889 m2-exp.y (The Modula-2 grammar)
890 parser-code.c (Code that is shared by the above grammar)
894 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
895 now necessary to use the Bison compiler compiler, since it
896 will generate function/variable prefixes other than yy.
898 Tue Jun 18 16:47:49 EDT 1991
900 symtab.[ch] Added the external variable working_lang, than holds the
901 value of the current working language.
902 Added the ennumerated type language_mode, with the values
903 language_auto and language_manual, the former meaning that
904 GDB sets working_lang as needed, and the latter meaning
905 that the value of working_lang is totally under user
907 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
908 REAL, BOOLEAN and CHAR. Also added the type codes
909 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
910 utils.c Added set_language_command and show_language_command to
911 implement the GDB support commands "set language" and
913 expression.h A number of identifiers were added to the type exp_opcode
914 to facilitate Modula-2 builtin functions, integer
915 division, and array indexing.
917 Wed Jun 19 13:25:58 EDT 1991
919 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
920 if the language specified by working_lang requires the use
921 of strict typing of expressions. Eventually, even this
922 will be able to be changed by the user.
923 Added the macro RANGE_CHECK, which evaluates to non-zero
924 if the language specified by working_lang requires the
925 checking of a value against the domain of its type.
926 Eventually, even this will be able to be changed by the
928 language.[ch] Predicates involving types (simple_type, ordered_type,
929 same_type, integral_type, numeric_type, character_type,
930 boolean_type, float_type) are added. These predicates are
931 based on the current value of working_lang, and are handy
934 Wed Jun 19 15:39:34 EDT 1991
936 eval.c Added the function type_array_rank which computes the rank
938 valarith.c Added the funtion value_bool, which when given a integer
939 value.h value (ie. struct value *) as an argument, it returns a
940 boolean value (ie. struct value *) true if that integer
941 is non-zero, and a boolean value false otherwise.
942 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
943 will print out properly.
945 Wed Jun 19 16:36:34 EDT 1991
947 valops.c Added the function value_capitalize, which returns it
948 value.h argument capitalized if its argument is a lowercase
949 letter, or the argument unchanged if its argument is not a
951 valarith.c Added the function range_check_p, which returns non-zero
952 value.h if its value argument is between the integral bounds upper
954 Added the function range_check_enum_p, which makes sure
955 that its value argument is a valid member of the domain of
957 Added the function range_check_range_p, which makes sure
958 its value argument lies between the upper and lower bounds
959 of its type argument, which must be a ranged type.
960 Added the function check_array_index, which range and type
961 checks an index of an array.
962 Added the function value_multi_subscript, which computes
963 array[idx1,idx2...idxN], given a value array and an array
964 of values representing indicies.
965 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
966 unpack_long to work with TYPE_CODE_BOOL and
969 Wed Jun 19 18:04:08 EDT 1991
971 symtab.c Stored pervasive types in a structure and make
972 lookup_pervasive_type() a lookup function that was based
973 on working_lang. If lookup_pervasive_type() returned
974 non-zero, then that value was returned (a fix, since
975 before it simply wouldn't return the pervasive type.)
976 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
977 non-zero if the language specified by working_lang means
978 "conversion" when it says "cast".
979 valops.c Added the function value_real_cast(), which performs a
980 value.h *cast*, not a *conversion*, which is what value_cast()
981 does when it can. In particular,
982 value_cast(<float_type>,4) = 4.0, while
983 value_real_cast(<float_type>,4) = some mess.
984 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
985 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
986 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
987 and MIN on integral types. *NOTE*: These are currently
988 hardcoded to work only if there are 8 bits per storage
990 eval.c Made logical functions call value_bool to return a
991 properly typed boolean value, based on working_lang.
993 Thu Jun 20 11:55:27 EDT 1991
995 valprint.c Types now print out in a Modula-2 fashion. This works for
996 the cases when the type is printed out step-by-step, that
997 is, it doesn't work when the name of a structured type
998 (which includes the keyword "struct", etc.) is simply
1000 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
1001 since type specifications in C and Modula-2 are very
1002 different. The C printing of a type is very recursive,
1003 whereas in Modula-2 it is generally very simple. C has
1004 type prefixes and suffixes, which have no real analogue in
1005 Modula-2. Maybe type_print() should call a language
1006 specific type printer. This is also advantageous if we
1007 compile GDB to exclude some of the languages. We'll just
1008 leave those functions out.
1010 Thu Jun 20 16:57:10 EDT 1991
1012 dbxread.c When reading the complete symbol table in (via
1013 psymtab_to_symtab()), the number and types of function
1014 arguments are added to a function type. define_symbol()
1015 calls add_param_to_type() to accomplish this.
1016 Assumption: when we come across a function definition
1017 (N_FUN symbol with an 'f' or 'F' in the name), its
1018 arguments will appear before another function definition.
1019 When a function is found, a pointer to its type is placed
1020 in the global in_function_type. Changes that
1021 add_param_to_type() makes are to this global.
1022 valprint.c The type of a function now includes (for Modula-2) the
1023 types of its parameters.
1024 eval.c Type checking and a check for the proper number of
1025 arguments is now done for function calls. Not sure of the
1026 impact this has on C++ member function yet.
1028 Thu Jun 20 19:58:48 EDT 1991
1030 valprint.c Rewrote the type printer. Broke it into two language
1031 specific parts, adding the functions type_print_m2() and
1033 An unfortunate consequence is this: if you debugging a C
1034 program in Modula-2 mode (why?), info types does not work
1035 well with regular expressions, since the types are printed
1036 out in Modula-2 terminology, but stored in C terminology.
1037 language.[ch] Added the functions new_type_last(), type_keyword(), and
1038 type_sep() to aid in the printing of typedefs.
1039 symtab.c Made the printing of typedefs as language independent as
1040 possible through calls to new_type_last(), type_keyword(),
1043 Fri Jun 21 11:50:26 EDT 1991
1045 dbxread.c Check all incoming ennumerated types. If it looks like
1046 Modula-2's BOOLEAN type, then change the type_code of the
1047 type to TYPE_CODE_BOOL so we can process it as a boolean
1049 valprint.c Replaced some of the 0x%x with calls to sprintf and
1050 hexformat() in val_print().
1051 language.[ch] Added the function hex_to_string(), which converts its
1052 integral argument to a hexadecimal number (format is
1053 language based) and returns the result as a string.
1055 Mon Jun 24 12:25:07 EDT 1991
1057 valprint.c Some functions call type_print_1() directly, instead of
1058 value.h using type_print(), so they can specify where (column) to
1059 print things. Since type_print() takes care of language
1060 dependence, that needs to be called first. Added a
1061 parameter depth to type_print() (so it is now like
1062 type_print_1). Changed type_print to type_print_at, and
1063 made type_print a macro that passes a depth argument of
1065 symmisc.c Changed all calls to type_print_1 to calls to
1067 Makefile.dist Made it possible to build GDB for a specific set of
1068 depend languages. Do this by passing a definition for the macro
1069 LANGS to make. LANGS should be a string containing a
1070 space-separated list of language names (ie. LANGS="c m2").
1071 The default is to build all languages. Note that grammar
1072 files must follow the naming convention of <lang>-exp.y.
1073 gdb.lang This holds the current value of the LANGS macro. It is
1074 examined every time make is called, and is updated if
1076 eval.c Added #ifdef _LANG_<lang> to these files.
1077 expread.c Still need to add them to dbxread.c and coffread.c.
1085 Mon Jun 24 16:33:11 EDT 1991
1087 language.[ch] Added the functions hexformat_pre() and
1088 hex_to_string_pre(), which take a prefix argument to
1089 include in the format string. Thus, hexformat_pre("08") will
1090 return "0x08x" (if the working language is language_c).
1091 Made hexformat() and hex_to_string() calls to the above
1092 with "" as the prefix argument.
1094 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
1095 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
1096 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
1097 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
1098 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
1099 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
1100 valprint.c, vax-pinsn.c
1102 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
1103 calls to hexformat() and hex_to_string(). Format strings without
1104 the leading "0x" were ignored.
1106 depend Updated to take the above into account.
1109 Tue Jun 25 15:27:18 EDT 1991
1111 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
1112 and type_check_t to keep track of the current state of
1113 range and type checking.
1114 main.c Added the variables range_mode, range_check, type_mode,
1115 and type_check to record the current state of range and
1116 type checking. Added initialization code to main().
1117 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
1118 the above variables.
1121 Tue Jun 25 17:57:08 EDT 1991
1123 dbxread.c process_one_symbol() updates the variable (enum language)
1124 source_lang based on the extension of the filename
1125 contained in the N_SO sybmol that started this symtab.
1126 When end_symtab() is called, the value of source_lang is
1127 put into the language field.
1128 stack.c select_frame() sets working_lang (and possibly type_check
1129 and range_check) to the language field of the symtab
1130 associated with the frame that is selected if working_mode
1131 is language_auto. If working_mode is language_manual, a
1132 warning is printed and working_lang is not set.
1133 language.c Added the function set_type_range(), which sets the value of
1134 type_check and range_check (if their modes call for
1135 automatic setting) based on the current value of
1136 working_lang. A non-zero argument will cause the current
1137 settings to be output.
1140 Wed Jun 26 14:51:40 EDT 1991
1142 eval.c Added range checks on assignment.
1143 m2-exp.y Added the grammar for sets to the language. Currently,
1144 these do not do anything except print an error message.
1146 Wed Jun 26 17:01:04 EDT 1991
1148 m2-exp.y Added the ability for parse_number() to parse negative
1149 numbers. A global flag is set upon encountering a unary
1150 minus. This was done to make, for example, 1 parse as a
1151 CARDINAL, and not as an integer, per Wirth's examples in
1152 Programming in Modula-2 ed.4.
1153 valprint.c Added support for "set radix 2" by then setting
1154 output_format to 't'.
1155 eval.c Implemented range checking on subrange types. Added calls
1156 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
1157 Implemented MIN and MAX for ennumerated types. The
1158 minimum value of an ennumerated type is defined by Wirth
1159 as the first identifier, and the maximum as the last.
1160 m2-exp.y Made octal numbers ending with "B" be characters and those
1161 ending with "C" be numbers, per Wirth's book. (p. 34)
1163 Thu Jun 27 14:11:52 EDT 1991
1165 stack.c select_frame() now only sets working_lang, it does not
1166 notify the user. If working_mode is language_manual, then
1167 a warning is issued once.
1168 main.c At the end of each call to execute_command(), working_lang
1169 is checked against the local static (enum language)
1170 current. If they differ and working_mode is
1171 language_auto, the new settings of language, type and
1172 range checking are printed out.
1173 stack.c Modified frame_info() to include the language of the
1174 current frame in the output of "info frame".
1175 language.[ch] Added the function language_str() which returns the name
1176 of the current language.
1178 Fri Jun 28 15:33:14 EDT 1991
1180 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
1181 the language. INCL and DECL currently cause an error,
1182 since sets are not implemented yet. INC and DEC are
1183 implemented as PREINCREMENT/PREDECREMENT with one
1184 argument, and as ASSIGN_MODIFY with two arguments.
1185 eval.c Added type checking to the above cases.
1186 value.h Added not_lval_constant to the lval_type ennumerated type.
1187 not_lval_constant means that the value is a constant
1188 value; that is 3 or 'a' or TRUE, not as in a constant
1189 identifier. This is used to help coerce numbers such as 3
1190 to either signed or unsigned numbers.
1191 valops.c Added the function value_coerce_constants() which coerces
1192 constant integers as following: if one is a constant and
1193 the other is not, the constant's type is set to the type
1194 of the other argument. If both are constants and one is
1195 signed, the other is converted to a signed constant.
1197 Sat Jun 29 17:26:29 EDT 1991
1199 valarith.c Added a better range checker. It now checks range
1200 (successfully) on integral operations [+-] (signed and
1201 unsigned) for any C sized type. Still does not work well
1202 for multiplication.)
1203 int_in_size() returns an integer that is coerced to fit into
1204 specified number of bytes.
1206 Mon Jul 1 13:04:14 EDT 1991
1208 language.[ch] Added the function binop_result_type(), which returns the
1209 builtin (struct type *) type that would be the result of a
1210 binop on the two values V1 and V2.
1212 Wed Jul 3 19:22:53 EDT 1991
1214 source.c Extended source_info() to include the source language in
1215 the output from "info source".
1217 Fri Jul 5 13:48:52 EDT 1991
1219 utils.c Moved the support functions for the GDB set/show commands
1220 dealing with language into language.c.
1221 language.c Added the function language_info(), which displays info
1222 about the current working language, type and range check
1223 settings. Called via the GDB command "info language".
1224 Added an initialization routine _initialize_language(),
1225 that sets defaults for the language, type and range
1226 variables and sets up the new GDB commands.
1227 main.c Language setup moved to language.c.
1230 Mon Jul 8 10:10:22 EDT 1991
1232 valarith.c Debugged the range checker for arithmetic. Still does not
1233 work for multiplication very well.
1235 Mon Jul 8 12:40:37 EDT 1991
1237 language.[ch] Added the function value_true() which returns non-zero if
1238 its argument represents a boolean true value.
1239 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
1240 check the truth of an expression.
1242 Thu Jul 11 12:51:34 EDT 1991
1244 language.[ch] Added the predicate structured_type(), which returns
1245 non-zero if the argument is a structured type.
1246 Added the predicate pointer_type(), which returns non-zero
1247 if the argument is a pointer type.
1248 eval.c Added the ability to do addition and substraction on
1249 pointers and integers. This case simply bypasses the
1252 Thu Jul 11 14:41:42 EDT 1991
1255 Added the symbol N_DEFD (0x4a) which is a definition
1256 module dependency that is used by the GNU Modula-2
1257 compiler and the linker. It is not important to GDB,
1258 except that [dbx|coff|mips]read.c should ignore these
1261 Fri Jul 12 16:07:00 EDT 1991
1263 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
1264 0 in val_print(). Also added statements to the else part
1265 to coerce type (argument to val_print) to a pointer type
1266 if it is an "array of unspecified length".
1267 valops.c Added the function value_m2_string(), which returns a
1268 (value) value which is a constant string, whose type is
1269 (ARRAY [0..n] OF CHAR). The length field of the type
1270 structure is set to zero, so it will be interpreted as an
1271 "array of unspecified length".
1272 stack.c Moved the language/frame mismatch check to
1273 main.c:execute_command().
1274 main.c The working language is recorded each time
1275 execute_command() is executed. If working lang has
1276 changed during its execution, then the new
1277 language/type/range info is printed out for the user. If
1278 the working language does not match the language of the
1279 frame, a warning is issued.
1281 Sat Jul 13 16:16:39 EDT 1991
1283 eval.c Moved all the type-checking stuff for operators to
1284 language.[ch] language.c. This is so we can keep language-specific
1285 stuff (like for what type operators are defined) in
1287 language.[ch] Added the function binop_type_check(), which checks to see
1288 if its two (value) arguments are type-compatible with its
1289 opcode argument. The opcode should represent an operation
1290 involving an operator. Also added the macro function
1291 unop_type_check, which calls binop_type_check with a
1292 NULL second argument.
1293 expprint.c Added Modula-2 operators to the op_print_tab, so info
1294 expression.h break works correctly. Also added "op_string", which
1295 returns the string corresponding to the (enum exp_opcode)
1296 opcode that is its argument.
1299 Sat Jul 13 18:26:18 EDT 1991
1301 coffread.c Added code to record the type of function arguments with
1302 each paricular function. Code is very similar to that
1304 dbxread.c Moved add_param_to_type() to symtab.c
1305 symtab.[ch] Added function add_param_to_type() from dbxread.c
1307 *** NOTE: The above additions have not been tested.
1309 Mon Jul 15 12:50:47 EDT 1991
1311 langauge.[ch] Added the functions type_error and range_error, which work
1312 like error() except if the type/range mode is set to
1313 *_mode_warn, then they do not do a return_to_top_level(),
1314 but merely print a warning.
1315 Also changed [set|show]_[type|range]_command() to support
1316 the new "warn" feature.
1318 Thu Jul 18 17:50:54 EDT 1991
1320 mipsread.c Added code to record the type of function arguments with
1321 each particular function. Code is very similar to that
1324 *** NOTE: The above additions have not been tested.
1326 Fri Jul 19 11:19:10 EDT 1991
1328 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
1329 UMIN_OF_SIZE, which when given a size of a numeric type,
1330 return the maximum and minimum value it can hold. UMAX...
1331 and UMIN... return the result for unsigned types.
1332 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
1333 struct types. They call above macros.
1334 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
1335 avoid a name conlict with the above.
1336 c-exp.y Added range checking on numeric constants in
1337 parse_number() for completeness.
1338 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
1339 return 0 if working_lang is not language_c.
1341 Thu Aug 8 14:17:22 EDT 1991
1345 breakpoint.c Documentation strings of some commands changed to
1346 eliminate the references to the C language where
1349 Tue Aug 13 15:48:03 EDT 1991
1351 m2-exp.y Added qualified identifiers to the grammar. The semantics
1352 are slightly different from those of the GDB operator ::
1354 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
1355 type_exp, where type_exp is any valid type expression.
1357 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
1358 printcmd.c Modified ptype_command() so it actually parses the input
1359 (necessary for type expressions with scope qualifiers).
1360 Added the function ptype_eval() which expects an
1361 expression composed of one OP_TYPE element.
1362 *.[ch] Replaced all occurences of parse_c_expression with
1364 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
1366 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
1368 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
1370 Small fixes from Peter Schauer:
1372 * infrun.c (child_attach): Lint.
1373 * solib.c (find_solib): Handle shared libs version 2.
1375 Small fixes from David Wood:
1377 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
1381 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
1382 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
1384 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
1385 chars_per_line is at maximum (user typed `set width 0'). Fix
1386 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
1388 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
1390 * coredep.c: include ptrace.h where necessary.
1391 * mipsread.c(parse_lines): fix unsigned char problem that was
1392 messing up line numbers on SGI's and possibly other MIPS based
1394 * infrun.c (child_create_inferior): use better test to check
1395 return val from setpgrp().
1396 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
1397 for sgi/irix support.
1399 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
1401 * mipsread.c (parse_symbol): Put non-static procedures
1402 in the global block.
1404 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
1406 Patch together `text_start' and `text_end' for 29K port.
1408 * exec.c (exec_command): If NEED_TEXT_START_END, define the
1409 variables and set them based on the exec file.
1410 * am29k-tdep.c: declare text_start.
1411 * valops.c (call_function_by_hand): declare text_end.
1413 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
1414 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
1415 because machines that do this will also have to know to
1416 set NEED_TEXT_START_END. Besides, it was a redundant way to
1418 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
1419 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
1420 NEED_TEXT_START_END.
1422 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
1424 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
1426 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
1427 Pass MUNCH_DEFINE to munch whenever we run it.
1428 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
1429 format string; use 0x%x instead.
1430 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
1431 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
1432 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
1433 * inflow.c: Handle `short' process group IDs.
1434 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
1435 and check for ptrace errors.
1436 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
1437 (coff_symfile_init): Initialize text_bfd_scnum.
1438 (read_coff_symtab): Use it to find the text [and absolute?] sections.
1439 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
1440 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
1441 Merge target arm case with other "easy" cases. Add target
1442 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
1443 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
1445 * minimon.h, remote-adapt.c, remote-mm.c: Add.
1446 * munch: Cope with RT/PC putting fns in data segment.
1447 Restore ability to override `nm' by specifying MUNCH_NM.
1448 * xconfig/rtbsd, xconfig/ultra3: New host systems.
1449 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
1450 and remote-adapt. Remove encapsulated coff #define's (the
1451 support should go in BFD, and gdb shouldn't know or care).
1452 * tconfig/a29k-kern: Same, but for remote kernel debugging.
1453 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
1454 * tm-29k.h: Update BADMAG (though it should go away).
1455 Allow the register definitions to be overridden in another
1456 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
1457 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
1458 DUMMY_SAVE_GR96, for handling kernel calling conventions
1459 that use GR64+ rather than GR96+.
1460 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
1461 remote debugging of Ultra3 kernel. Includes tm-29k.h and
1462 overrides various things.
1464 * remote-mm.c (mm_attach, mm_wait): Handle attach like
1465 child_attach does, making a clean stop in the newly attached
1467 * remote-eb.c: Lint.
1469 * coffread.c: Make coffread independent of any particular
1470 variant of COFF. Avoid #include-ing any particular one except
1471 internalcoff.h. BFD now passes key values for symbol reading
1472 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
1473 and the symbol masks and shifts); use them.
1474 Remove obsolete end_of_text_addr.
1476 * exec.c: Remove unused include files.
1478 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1480 * Makefile.in (documentation targets): Pass $(M4).
1481 Bugfix from eggert@twinsun.com (Paul Eggert).
1483 * stack.c (down_silently_command): Check for stack existence.
1485 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1487 * Makefile.in (VERSION): Update to 4.0.3.
1489 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1491 * core.c (core_file_command): Print frame at coredump with
1492 its level number, by calling print_stack_frame.
1493 * frame.h: Add selected_frame_level, print_stack_frame.
1494 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
1495 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
1496 Change print_sel_frame and print_selected_frame callers to
1499 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
1500 * symfile.c (free_named_symtabs): Ditto.
1501 * main.c (main): wrap_here needs an arg.
1502 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
1503 (solib_add): Avoid noise.
1504 (solib_create_inferior_hook): Lint.
1505 (sharedlibrary_command): Move dont_repeat to here.
1506 * utils.c (error): Call wrap_here to force buffered output.
1508 Small patches from Peter Schauer:
1510 * coffread.c (start_symtab): Free any existing line_vector before
1512 (read_coff_symtab): Ditto for type_vector.
1514 * source.c (lines_to_list): New variable, replacing function.
1515 (all uses): Use as variable.
1516 (_initialize_source): Add 'set listsize' and 'show listsize'.
1517 * utils.c (lines_to_list): Remove function.
1518 * stack.c (print_frame_info): Use as variable.
1519 * defs.h (lines_to_list): Remove declaration.
1521 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1523 * breakpoint.c (insert_breakpoints): Restore warning about
1524 the program might be running in another process, but only for
1525 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
1526 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
1528 * utils.c (error): if error_pre_print is set, print the string
1530 * main.c (main, print_gnu_advertisement, print_gdb_version):
1531 Reformat legalese so it always prints, but acts as an "I'm here"
1532 message while symbols are being read. If any errors occur,
1533 print a few newlines to set off the message and start it at the
1534 left margin. Remove mention of "help" command, and don't yak
1535 about symbol reading.
1536 (catch_errors): Error string is now printed first in case of
1538 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
1539 suggest the "help" command.
1541 * Makefile.in (VERSION): Set to 4.0.2.
1543 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
1545 * .gdbinit: Remove useless "rr" command. Set complaints
1546 to 1 for people debugging gdb.
1548 * breakpoint.c, remote-vx.c: Reword strings printed by
1549 catch_errors callers.
1551 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
1553 * WHATS.NEW: "history write -> history save". Doc "write on/off".
1554 (Fix from kenc@viewlogic.com.)
1556 Fix some infrastructure to be able to cope with host and target
1557 machines with different sized basic types (ints, ptrs, etc).
1558 (Idea from pierre@la.tce.com (Pierre Willard).)
1560 * values.c (value_from_longest): Rename from value_from_long.
1561 Handle pointer types as well as integers, so that targets with
1562 different pointer sizes from the host can be accomodated.
1563 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
1564 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
1565 uses of value_from_long to value_from_longest.
1566 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
1567 the correct pointer type to value_from_long{est}.
1569 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
1571 * remote-vx.c: Remove obsolete code for calling functions via
1572 vxworks kludge interface (it referenced value_from_long).
1574 * valops.c (value_string): Find malloc with lookup_misc_func, not
1577 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1579 Make writing to files work properly. (Fixes to BFD are also needed.)
1581 * core.c (core_open): Open file ourselves, read or r/w, depending on
1582 write_files. Use bfd_fdopenr.
1583 * gdbcore.h (write_files): New variable.
1584 * exec.c (write_files): Define variable, add set&show for it.
1585 (exec_file_command): Use write_files to open for read or r/write.
1587 Make shared library reading happen automatically. These changes
1588 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
1590 * inferior.h (stop_soon_quietly): Add to exported variables.
1591 * infrun.c (child_create_inferior): call solib hook, if defined.
1592 (child_attach): call solib hook, if defined.
1593 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
1594 (find_solib): Use lookup_misc_func rather than hand-rolled.
1595 (symbol_add_stub): New stub for catch_errors.
1596 (solib_add): Avoid output if !from_tty. Catch errors rather
1597 than just calling symbol_file_add and bombing.
1598 (solib_create_inferior_hook): Interface with the target process
1599 to let it read and alloc shared libs, then figure out what it did.
1601 * core.c (validate_files): Fix typo, soften warning.
1602 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
1604 * utils.c (fputs_demangled): Avoid duplicate printing if
1605 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
1607 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
1608 (Fix from pierre@la.tce.com (Pierre Willard).)
1610 * main.c (catch_errors): Change argument to a char * from an int,
1611 since a char * can point to a struct full of glop, but an int
1612 is not guaranteed to be able to hold a pointer.
1613 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
1614 breakpoint_re_set_one, breakpoint_re_set): Adapt.
1615 * core.c (core_open, solib_add_stub): Adapt.
1616 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
1618 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1620 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
1621 by adding .NOEXPORT target.
1623 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1627 * Makefile.in (VERSION): Roll to 4.0.
1628 (gdb.tar.Z): Make refcard.ps as well, for shipment.
1630 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1632 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
1635 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
1638 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
1640 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
1641 reflect above name change
1643 * WHATS.NEW: correct pointer to refcard.
1645 * doc/gdb.texinfo: update New Features, Installing
1647 * doc/gdbint.texinfo: add short description of configure +template
1649 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1651 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
1653 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
1655 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
1656 tar file, add dependencies for referenced doc files.
1658 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
1660 * coffread.c, symfile.c, stack.c: saberized.
1662 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1664 * doc/refcard.tex: permuted Essential Commands sec
1666 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
1668 set/show symbol-reloading
1669 default set complaints 0
1671 RET-repeat disabled after prompted long displays
1672 processID (attach) interpretation of 2nd GDB cmdline arg
1674 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
1676 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
1677 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
1678 breakpoint.c, main.c: lint.
1680 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1682 Install new configuration scheme for GDB and friends.
1684 * config.sub: Translate ordinary names to three-part names.
1685 * configure: Use three-part names internally.
1686 * configure.in: Translate three-part names to filenames.
1688 * README, WHATS.NEW: Update for gdb-4.0.
1689 * Makefile.in: Roll VERSION to 3.99.
1691 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
1693 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
1694 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
1695 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
1696 to single structures rather than arrays; when passing
1697 their address, use &. This avoids trouble with bdead compilers.
1698 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
1699 instead. This avoids portability headaches.
1700 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
1702 * source.c (open_source_file): Avoid ANSI const bdeath by
1703 skipping declaration and then casting result value.
1704 * tm-hp300bsd.h: Clarify comment.
1705 * utils.c (strstr): Result is const char *; ANSI bdeath.
1706 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
1707 since system include file defines it differently from "defs.h",
1708 though the two are equivalent for our purposes.
1709 * tconfig/hp300bsd: Add m68k-tdep.o.
1711 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1713 * tconfig/sun*4: Remove warnings about system assembler.
1715 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1717 * mcheck.c: Avoid warning about undeclared abort fn.
1718 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
1719 it causes recursive calls to error() when used in cleanups.
1720 To do so requires that we make it a function, so we do.
1721 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
1722 * utils.c (do_cleanups): Remove the current cleanup from the
1723 chain *before* calling it, in case error() is called from it.
1724 The result won't be pretty, but won't be an infinite loop either.
1726 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
1728 * dbxread.c (read_struct_type): Grok anon structs for C++.
1729 (vb_name, vptr_name): Null terminate these strings.
1731 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1733 Minor bug fixes from BSD Net2 gdb:
1735 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
1736 returns 0, there is no previous frame.
1737 * breakpoint.c (commands_command): If !from_tty, don't call
1738 input_from_terminal_p().
1739 * dbxread.c (record_misc_function): Speed up slightly.
1740 (compare_psymbols): Ditto.
1741 * infcmd.c (do_registers_info): Take a second argument to
1742 determine whether to print float registers. "info registers"
1743 does not do so anymore. "info all-registers" does, now.
1744 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
1746 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
1747 * inflow.c (initialize_inflow): Set tflags_ours correctly.
1751 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
1752 executing_breakpoint_commands if we are interrupted by error.
1753 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
1754 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
1755 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
1756 catch_errors() so we can setup the frame regardless of whether
1757 the shared libs work.
1758 * ieee-float.c (double_to_ieee_extended): Get exponent from
1759 right place in little-endian systems. From John Carey.
1761 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1763 * main.c: Remove unused terminating_signals and catch_termination().
1764 (long_options): Terminate with a zero element.
1765 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
1766 (gdb_readline): Make call-compatible with readline.
1767 (init_signals): Improve comments re vfork vs. signal.
1769 * utils.c (prompt_for_continue): Use new gdb_readline().
1770 If we prompt for continuation, we don't let CR repeat the previous
1771 command, once we get back to a prompt. It's too easy to keep
1772 hitting CR, expecting "--more--" prompts, and have some long
1773 command start repeating on you.
1775 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1777 * blockframe.c (frameless_look_for_prologue): Speed up by
1778 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
1779 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
1780 Define two variants, one faster.
1781 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
1782 and return zero, rather than giving an error.
1783 (setup_arbitrary_frame): Initialize the PC in the new frame.
1784 (skip_prologue): Add a second arg saying whether we're just
1785 checking for a frameless function or not.
1787 * core.c (core_open, core_close, core_xfer_memory): Move
1788 section table pointers and bfd* into the target_ops.
1789 (core_open): Allow errors in shared lib reading, etc.
1790 (core_files_info): Describe shared library sections.
1792 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
1793 exec_files_info, set_section_command): Move section table
1794 pointers and bfd* into the target_ops.
1795 (add_to_section_table): Add BFD to section table.
1797 * target.c (target_xfer_memory, target_info): Pass target to
1798 xfer_memory and target_info functions.
1801 * gdbcore.h: Move struct section_table.
1802 * target.h: New home of struct section_table.
1804 * solib.c (solib_add): New argument is the target_ops whose
1805 section list is to be added to, if any. Reallocate the
1806 sections in that target to add any that come from shared libs.
1807 (throughout) so_sections renamed to sections.
1808 (solib_xfer_memory): Deleted.
1809 * tm-sunos.h (SOLIB_ADD): Add target argument.
1810 (SOLIB_XFER_MEMORY): Delete.
1812 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1813 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
1814 from target_ops. It's the same on all targets. Add two section
1815 pointers to target_ops.
1817 * stack.c (find_relative_frame): Dump ancient algorithm for
1818 "down", just use handy "next" pointers.
1819 (frame_command): Don't error if there is no stack; let user
1822 * inflow.c (new_tty_prefork, new_tty): New prefork routine
1823 modifies static state in the parent process; new_tty itself
1824 runs in the child and modifies the child's file descriptors
1825 to match the saved static state.
1826 * infrun.c (child_create_inferior): Call new_tty_prefork,
1829 * infptrace.c (child_xfer_memory): Add ignored target arg.
1830 * remote-eb.c (eb_xfer_inferior_memory): ''
1831 * remote-nindy.c (nindy_xfer_inferior_memory): ''
1832 * remote-vx.c (vx_xfer_memory): ''
1833 * remote.c (remote_xfer_memory): ''. Rename from
1834 remote_xfer_inferior_memory.
1836 * main.c (main): Only try to attach "corefile" argument if
1837 it starts with a digit.
1839 * symfile.c (symbol_reloading): New "set/show" variable.
1840 (symbol_file_add): Shorten message about symbol reading.
1841 (add_symbol_file_command): Merge with add_syms_addr_command,
1842 since this should work on all targets now.
1843 (stop_whining): Default to zero, to shut up complaints
1844 about bad symbol tables on many systems.
1845 (free_named_symtabs): Just exit unless symbol_reloading.
1847 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
1848 and add comment explaining shared library screw.
1850 * source.c: #if defined => #ifdef.
1852 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1854 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
1856 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1858 * doc/rdl-apps.texinfo: provide default readline-appendix finder
1859 (doc/Makefile knows how to make one for local config)
1861 * Makefile.in: use doc/Makefile for doc targets
1863 * doc/Makefile: GDB documentation now has its own Makefile
1864 doc/refcard.tex: renamed from "gdbrc.tex"
1865 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
1866 doc/gdbint.texinfo: add markup in "Cleanups" chapter
1869 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1871 * values.c (baseclass_addr): When reading target memory, use the
1872 length of the basetype, not the upper type. We've only malloc'd
1873 enough space for the basetype, leading to errors in free().
1875 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
1876 ends up as a function specially, since we know the actual type of
1877 the pointed-to address. This (somewhat) fixes display of
1878 expressions that include misc_function_vector names. Try `cond 1
1879 !strcmp("a","b")' then `i b'.
1881 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
1882 The child can be proceeded from inside wait_for_inferior in
1883 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
1884 getting skipped in that case.
1886 * expprint.c (print_subexp): Use filtered output, since the
1887 subroutines we call use it, otherwise the output is horribly
1888 mangled, since output of wrappable stuff comes out late.
1890 * Makefile.in: Bump VERSION to 3.98.1
1892 * infrun.c (child_create_process): Use execlp to find the
1893 shell to exec our target program. This requires some fiddling
1894 with `environ' since there is no execlpe().
1896 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1898 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
1899 Minor rearrangement of refcard permits two new make targets--
1900 gdbrc.dvi DVI output for refcard, using CM fonts
1901 gdbrc.ps PostScript refcard, using PS fonts
1903 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1907 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
1908 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
1910 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1912 * doc/gdb.texinfo: last changes for release.
1913 Minor typo and formatting fixes; incorporated most fixes remaining from
1914 filed mail commenting on earlier drafts.
1916 Added warnings: pipes don't work in run command;
1917 conditions are converse of assertions;
1918 step over fn without debug info goes to next fn;
1919 vars may have "wrong" values near fn entrance, exit
1921 Added example from Kingston on printing repeated nonadjacent values
1923 Added explicit mention that in Emacs gdb mode C-c and C-z are like
1924 shell mode for signals
1926 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
1927 doesn't sound so much like its parent "Stopping and Continuing"; also
1928 moved entries on continue to top of section, so they don't get lost.
1930 Improved installation directions in appendix, added manual formatting
1933 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1935 * configure.in: Remove xm.h and tm.h even if we aren't linking
1936 new ones, so "./configure sun4; ./configure none" does the right
1937 thing. Assume that alldeps.mak and depend are already built in
1938 srcdir, and avoid running "make" (particularly "make depend",
1939 which involves "gcc") from inside configure. Build Makefile
1940 directly rather than building Makefile.conf first.
1941 * configure: Regenerate with above changes.
1942 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
1943 to 3.98. Revise gdb.tar.Z procedure to produce a file
1944 called gdb-$(VERSION).tar.Z but which unpacks into a
1945 directory called "gdb". Move non-source files out of
1946 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
1947 (depend): Don't try to do "gcc expread.y".
1948 (expread.o): Update dependencies by hand.
1950 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1953 Fixed a variety of small typos that prevented info from formatting
1954 cleanly; altered too-long heading for GPL Appendix, as discussed
1955 w/RMS; Changed date on cover to July 91.
1957 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1960 (1) Applied some fixes due to comments from Larry Breed (easier ones
1961 through chapsec 5.2)
1962 (2) Eliminated use of @footnote---had my doubts about it anyways, and
1963 it's broken in latest texinfo
1964 (3) Introduced *some* use of [] for optional arguments, where
1965 explanation is not simpler by listing cmd w arg and cmd w/out arg
1966 separately. Still not using @deffn.
1967 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
1968 couple of headings are too long. Need patches to texinfo or revision
1971 * Partial update to README (which still needs work for this
1972 release!): (1) use of configure corrected for new script,
1973 (2) "make gdb.dvi" and "make gdb.info" mentioned.
1975 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
1977 * symtab.c (lookup_symbol): Don't complain right off about
1978 no debug symbols; use the misc function vector first.
1979 (list_symbols): Use misc function vector to find symbols
1980 that don't have debug info, and print them.
1981 (find_pc_symtab): Temporarily avoid fatal() when psymtab
1982 PC range doesn't match symtab PC range, as it does on the
1983 MIPS because our symtab reading isn't perfect.
1985 * dbxread.c (dbx_symfile_read): Make warning about
1986 "no debug symbols" slightly nicer.
1988 * source.c (select_source_symtab): If "main" symbol exists,
1989 but decode_line_spec can't find line info, don't just return
1990 a zero; try other source symtabs or give an error.
1992 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
1993 their low addresses first, then rip through fixing high addrs.
1995 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
1996 <runene@ifi.uio.no>.
1997 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
1999 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2001 * Minor, mostly mechanical, cleanup of doc subdir for clean
2002 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
2003 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
2005 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
2007 Mostly MIPS and general symbol-reading fixups.
2009 * doc/gdbint.texinfo: Add documentation on symbol-reading
2012 * mipsread.c: Remove kludges around #include "ecoff.h".
2013 Remove redefinitions of a_magic, etc, no longer used.
2014 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
2015 Fix global overview comments to match symfile.c protocol.
2016 (mipscoff_new_init): Eliminate cur_hdr if we have one.
2017 (mipscoff_symfile_read): Eliminate unused code. Avoid
2018 sorting all the symtabs, when all we have read here is psymtabs.
2019 The symtabs are sorted as they are created anyway. Tell
2020 condense_misc_bunches whether we're mainline.
2021 (psymtab_to_symtab_1): Pass filename when recursing, to make
2022 stack trace more informative.
2023 (parse_partial_symbols): Assume cur_hdr as argument.
2024 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
2025 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
2026 the TYPE_NAME of char *, since that's done in symfile.c.
2027 (free_numargs, parse_symbol, add_symbol, add_block,
2028 shrink_linetable): Declare these fns void.
2029 (upgrade_type): Convert tree of if's to switch. Clean up
2030 bogus "off == 0" handling with a complaint. Avoid setting
2031 field bitpos and bitsize of array with lower and upper bounds.
2032 Check specified bitsize of elements against their actual type's
2033 bitsize, and complain if different. Complain about unknown
2035 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
2036 (psymtab_to_symtab_1): Print names of subsidiary files that
2037 are being read in. FIXME, we read far too many files. This code
2038 is not the problem, the problem is in parse_fdr where the psymtabs
2040 (cross_ref): Result should indicate that we used one aux entry
2041 normally, or two if we encountered a "next" entry. This used
2042 to leave the caller pointing at the wrong aux entry.
2043 (add_symbol): If overflowed cur_block, reallocate it larger,
2044 chase all pointers to it, and complain(), rather than clobber memory.
2045 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
2046 (new_field): Only allocate one field initially, not two.
2047 Pull ++ out of macro argument. Simplify.
2048 (_initialize_mipsread): Avoid initialization of importd
2049 global_psymbols and static_psymbols.
2051 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
2052 to properly set pst->symtab; avoid searching for it.
2053 (symfile_fns): Improve comments, add a FIXME.
2054 * dbxread.c: Update comments to reflect symfile protocol.
2055 (read_ofile_symtab, end_symtab): Return the symtab.
2056 (psymtab_to_symtab_1): Set pst->symtab.
2058 * coffread.c (coff_symfile_read): tell condense_misc_bunches
2059 whether we're mainline.
2061 * symfile.h (sym_fns): Remove unused sym_discard member.
2062 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
2064 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
2065 the environment variable is not.
2066 * infcmd.c (finish_command): Use filtered printfs.
2067 * cplus-dem.c: Add struct tags to a few unnamed structs.
2068 * valops.c (value_coerce_array): Improve comments.
2069 * valprint.c (type_print_varspec_suffix): Print array size only
2070 if greater than zero.
2071 * m88k-tdep.c: Shift some lines left by one space, that had
2072 apparently been trashed at some point.
2073 * TODO: More things to do, a few got done.
2075 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2077 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
2078 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
2080 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
2081 * expread.y, findvar.c, symmisc.c: Ditto.
2082 * printcmd.c (address_info): Update printed forms of LOC_
2083 symbols. Elim LOC_EXTERNAL.
2084 (print_frame_args): Keep track of param stack offsets before
2085 re-looking up to find the local register param is kept in.
2087 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
2088 Further integration of mipsread into gdb. Eliminate unused
2089 routines, duplicate declarations. Handle static symbols in
2090 psymtabs as well as external symbols. When reading symtabs,
2091 insert symbols into the correct block (global, static, or a local
2093 (read_mips_symtab, parse_partial_symbols): Don't pass useless
2095 (mipscoff_symfile_read): Don't call select_source_symtab.
2096 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
2097 rather than SYMBOL_VALUE.
2098 (parse_external): Comment clobbering of top_stack.
2099 (parse_partial_symbols): Update comments. Allocate and parse
2100 static symbols as well as external symbols. FIXME, enum values
2101 are not handled in this pass, but should be. Inline new_psymbol.
2102 Use SYMBOL_VALUE_ADDRESS.
2103 (psymtab_to_symtab_1): Read symbols into global static block
2104 by default (until enter some function's local block context).
2105 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
2106 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
2108 * source.c (select_source_symtab): Select a source symtab
2109 from either the symtabs or, failing that, the psymtabs.
2110 (list_command): Update error message.
2111 (forward_search_command, reverse_search_command): Use getc, not
2112 fgetc, for speed. FIXME, add comment about buffers that die if
2113 overrun by long line.
2115 * values.c (unpack_field_as_long, modify_field): Avoid shifting
2116 by an entire word, which is not portable, if we have a 32-bit
2117 field. (Code in dbxread.c already turns such bitfields, if
2118 aligned, into ordinary ints, but fixing this will help for other
2119 symbol formats and for future changes.)
2120 * core.c (core_open): Handle ANSI const brain death.
2121 * utils.c (vprintf): Fix varargs typo.
2123 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
2125 * findvar.c (find_var_value): Handle &function better.
2126 * TODO: Document work needed on &fn and &array.
2127 * printcmd.c (print_address_symbolic): New arg is the prefix
2128 to print if a name is printed.
2129 (print_address_demangle): Honor "set print address" now.
2130 Use new arg above to improve spacing of output.
2131 * valprint.c (val_print): When printing function pointers,
2132 print symbolic form too.
2133 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
2135 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2137 * core.c (memory_error): Reword error msg to mislead less.
2139 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
2141 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
2142 parse_partial_symbols): Use newer BFD internals (external_filehdr
2143 and external_aouthdr), byte-swap the fields that we care about
2144 before using them, and make the file header data local to
2145 read_the_mips_symtab rather than global.
2147 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
2149 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
2150 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
2152 * main.c (command_line_input): Flush stdout and stderr
2153 before every call to readline. This reportedly fixes a bug
2154 that comes up in Sys V running emacs-gdb and/or xxgdb,
2155 when stdin/out are pipes or sockets.
2157 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2159 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
2160 Avoid declaring Makefile dependencies, because GNU Make stupidly
2161 tries to update it if we do.
2163 * coffread.c: Revise for minor changes to bfd internal coff
2166 * configure: If -template= is given a relative path, make it
2167 absolute before recurring in subdirectories.
2169 * configure, configure.in, Makefile.in: Install "configure" script
2170 as replacement for config.gdb.
2171 * config.gdb, Makefile.dist, Makefile.sdir: Remove
2172 * README: Update for configure, mostly. FIXME.
2174 * Add dec3100 as equivalent to littlemips. Indicate in all host &
2175 target config files that they are for the host. When the lines
2176 get copied into the Makefile, this makes it more obvious what's
2179 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2181 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
2182 tabs, which end up in the disassembler output inadvertently.
2184 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
2186 Make it compile cleanly in an ANSI GCC2 environment.
2188 * blockframe.c: <stdio.h>
2189 * cplus-dem.c: free takes a void *, ifdef __STDC__
2190 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
2192 * defs.h (alloca): Avoid doing anything if alloca already def'd.
2193 * stddef.h, stdlib.h: Remove these files.
2194 * symtab.c: Avoid declaring qsort, close.
2195 * symfile.c: Avoid declaring close.
2196 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
2197 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
2199 Assorted other changes.
2200 * dbxread.c: include "libaout.h", not "liba.out.h".
2201 * printcmd.c (print_frame_args): Set recurse properly for
2202 indentation of struct and array parameters.
2203 * valops.c (value_cast): Allow cast to void.
2204 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
2205 single_step() in a target-independent fashion.
2206 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
2207 set up to be ready to continue. This makes us target independent.
2208 * infptrace.c (child_resume): Remove call to single_step; now
2209 can single step a SPARC target of any kind.
2211 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2213 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
2214 docn into separate sections---basically chapters, plus two loose
2215 pieces that can be configured to go in different places. This
2216 allows GNU m4 to preprocess the manual without coredumping.
2218 * Makefile.dist: tell TeX where to find texinfo.
2220 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2222 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
2223 the new target "rdl-apps.texinfo" which captures the Makefile
2224 variable that records where to find the Readline libraries.
2226 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
2228 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
2229 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
2230 * defs.h (const, volatile): Only define if not already defined.
2231 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
2233 * README: Update for release 3.95.
2234 * config.gdb: Don't create readline dir in subdir builds.
2235 * main.c: Include with "..." form for non-system include files,
2236 so "gcc -MM" for "make depend" works.
2237 Include readline files with "...h" rather than <readline/...h>.
2238 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
2240 * coffread.c: Undo minor damage done by Rich Pixley. Use
2241 different internal and external representations of COFF
2242 data structures. Use new BFD routines for swapping them in and
2244 * symfile.c (free_named_symtabs): Avoid freeing file names that
2245 are null or empty. Old i960 tools seem to produce files that
2246 claim to have empty names, causing each successive file read
2247 to blow away the previous one.
2248 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
2249 Move deferred_stores to top of file, but don't separate its
2250 #define's from its variable. Add commentary.
2251 * Makefile.dist: Fix Rich damage; undo "configure" changes in
2252 favor of keeping the (working) config.gdb. Move readline
2255 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
2257 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
2259 * infptrace.c (fetch_registers): no result, since now void.
2260 * tconfig/news: target depends on m68k-tdep too.
2262 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2264 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
2267 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
2268 applied various small fixes due to or inspired by RMS comments
2270 * doc/gdb.texinfo: finished using all RMS comments, save those for
2271 appendices on readline and cmd history (which are in other source
2274 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2276 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
2277 chapter 9; (2) documented 'break' command's menu mode for
2278 overloaded names, in response to hgs problem report C++ p-31
2280 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2282 * doc/gdb.texinfo: (1) better introductory example; (2) more
2283 consistent use of @code, @samp, @file, @kbd throughout; small
2284 cleanups to first three nodes; (3) new "Contributors" node;
2285 (4) Appendix, Renamed Commands; (5) divert specialized startup
2286 instructions to "Targets" chapter for generic manuals, while
2287 leaving them up front for manuals specific to specialized
2288 environments; (6) apply fixes from RMS comments through chapter 4.
2290 * pretex.m4: modify explanatory text slightly (and redefine
2291 "regexp") to keep GNU m4 from complaining. (It still crashes
2292 later, but one step at a time...)
2294 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
2296 * readline/readline.c (update_line): Avoid dereferencing a pointer
2297 before comparing it to its bounds. Saber caught this.
2298 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
2299 and only set PC if tgetstr returned non-null. Saber caught this.
2301 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2303 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
2304 stuff for config manual) here where it counts; updated
2305 to use new subdir structure (gdb/doc/).
2307 * Makefile: generated from above via
2311 * gdbint.texinfo: added instructions on generating gdb.info* files
2312 locally for release. These are ordinary info
2313 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
2314 Makefile)---but due to use of texinfo 2, can't count on makeinfo
2315 to generate these, so we distribute them already formatted.
2317 * gdb.texinfo: included full Info node and menu crud (as generated
2318 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
2320 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
2321 put in comments-for-future gdb.info target (one day makeinfo will
2324 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2326 * gdb.texinfo: Updated to include new or old undocumented
2327 commands, at least the following (perhaps some others I forgot to
2328 record): info f, info float, info path, info program, info s, info
2329 set, info source, info terminal, info types, info user, set/show
2331 Also covered all recent GDB command renames for v4.
2333 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2335 * mipsread.c: Rather than keeping count of how many symtabs
2336 and psymtabs we have, for sorting purposes, count them when
2337 we need to sort. This fixes bug in rereading of symbol tables.
2339 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2341 * infcmd.c: renamed "info path" to "show paths"
2342 * gdbrc.tex: documented above.
2344 Wed May 8 04:51:11 1991 John Gilmore (gnu at cygint.cygnus.com)
2346 * remote.c: Fix comments.
2347 * utils.c (error): Force out any pending wrap output.
2349 Sat May 4 11:11:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2351 * Makefile.dist: Roll VERSION to 3.95.
2352 Fix up "saber_gdb" to work again.
2353 * saber.suppress: Update.
2355 * coffread.c, exec.c, infptrace.c, inftarg.c, remote.c, solib.c,
2356 symtab.h, target.c, target.h: Lint.
2357 * core.c: setup and select frame after reading shared libs,
2358 else reading shared libs will clobber them. Lint.
2359 * utils.c (error): Force out any buffered wrap text.
2361 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2363 * remote.c: Remove decls of memory_insert_breakpoint
2364 and memory_remove_breakpoint, no longer used. (Suggestion of
2367 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
2368 to make it easier to interface to "configure"'d libraries.
2370 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
2372 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
2373 aliases for set/show print.
2375 Thu May 2 11:22:02 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
2377 * coffread.c (coff_sym_fns) [TDESC]: Make the type be m88kbcs.
2379 * m88k-tdep.c (IEEE_isNAN): New function.
2381 * infrun.c, m88k-tdep.c, m88k-xdep.c: Change

2388 * m88k-xdep.c: #if 0 out push_breakpoint.
2390 * tm-88k.h: Define GET_SAVED_REGISTER.
2392 * tm-88k.h: Define DGUX.
2394 * m88k-opcode.h (UEXT, SEXT, MAKE): Put parentheses around arguments.
2396 * m88k-pinsn.c (sprint_address): Declare at top of file.
2398 * m88k-xdep.c: #if 0 out core_file_command.
2400 * values.c ({unpack_,value_as_}pointer): Just call
2401 {unpack_,value_as_}long (for now anyway).
2403 * m88k-tdep.c (get_saved_register): Make get_reg a dc_word_t (*)().
2404 (psr_register): Change return type to dc_word_t.
2406 * m88k-tdep.c (tdesc_read_function): Comment out call to ptrace.
2408 * m88k-tdep.c (get_saved_register): Add lvalp parameter.
2410 * gdbcore.h (write_memory): Don't prototype it.
2412 * tm-88k.h, m88k-tdep.c: Make stack_error, stack_jmp global.
2413 m88k-xdep.c: Don't mention stack_error.
2415 * {x,t}config/m88k ({X,T}DEPFILES): Add missing files.
2417 * mtrace.c: Don't typedef things like size_t, just #define them.
2419 * coffread.c [TDESC]: #if 0 out references to coffsyn.
2421 * symtab.h (struct symtab): Include EXTRA_SYMTAB_INFO.
2422 tm-88k.h: Define EXTRA_SYMTAB_INFO.
2424 * coffread.c [TDESC]: Include "tdesc.h" and make tdesc_handle
2425 dc_dcontext_t not int.
2427 * coffread.c [TDESC]: Use system include files not <intel-coff.h>.
2429 * coffread.c [TDESC]: Move setting of debug_info from
2430 coff_symfile_read to find_linenos and make it work with BFD.

2900 Rename {copying,warranty}_info to show_{copying,warranty}.
2902 * symfile.c: Rename add_syms_command to add_symbol_file_command.
2903 (_initialize_symfile, add_syms_addr_command):
2904 Rename add-syms to add-symbol-file.
2906 Thu Apr 18 18:08:30 1991 John Gilmore (gnu at cygint.cygnus.com)
2908 * symfile.h (free_named_symtabs): Rename from free_named_symtab.
2909 * symfile.c (clear_symtab_users_once, cashier_psymtab,
2910 free_named_symtabs): Move these routines from symmisc.c.
2911 * symmisc.c (same): same.
2912 (free_symtab): Make non-static.
2913 * symtab.h (free_symtab): Declare as exported void fn now.
2914 * dbxread.c (end_symtab, end_psymtab): Change comments.
2915 (initialize_dbxread): Call dbx_new_init() in case the first
2916 command is add-symbols.
2917 * target.c (dummy_target): Permit add_syms_addr_command.
2919 Sat Apr 13 14:46:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2921 Permit symbols to be superseded when new symbol files have
2922 been read in, particularly for VxWorks.
2924 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
2925 to the main file, as well as to include files. Also, put global
2926 functions into the global psymtab, to make "i fun" work.
2927 (end_psymtab): Free named symtabs and psymtabs for a file, once a
2928 new psymtab for it has been read.
2929 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
2930 a file, once a new symtab has been read for it.
2931 * mipsread.c: FIXME. We need to do the same for MIPS, but it
2932 looks harder to determine the top-level block before it's been
2933 queued to the psymtab list.
2935 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
2936 If we have wiped out any old symbol tables, clean up at end of
2938 (symbol_file_command): Don't reference symfile_fns if it's zero.
2940 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
2941 defines for the blocks of a blockvector that contain global and
2942 file-static symbols and the first of the smaller scope contours.
2943 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
2944 decode_line_1, make_symbol_completion_list): Use the above.
2945 * coffread.c (end_symtab, patch_opaque_types): Ditto.
2946 * dbxread.c (end_symtab): Ditto.
2947 * expread.y (block): Ditto.
2948 * mipsread.c (throughout): Ditto.
2949 * symmisc.c (free_named_symtabs): Ditto.
2951 * symtab.c (list_symbols): Process the first symbol of the
2952 static psymbols list.
2953 (types_info): Restore this function from its untimely #if 0.
2954 It's not perfect, but it is better than nothing.
2955 (_initialize_symtab): Restore "info types".
2957 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2959 * m68k-stub.c: Remote stub for 680x0's, created from
2960 rem-m68k.shar (which is removed).
2961 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
2962 Remove RCS log stuff now that we use CVS and it blows our diffs.
2964 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2966 * symmisc.c (free_named_symtab): Make it work, in its current
2967 kludgy fashion. Change result to indicate if we blew away bkpts.
2968 * dbxread.c (end_symtab): Accumulate result from
2969 free_named_symtab and print warning if we blew user's state.
2970 * symfile.h: free_named_symtab now returns an int.
2972 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
2974 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
2975 is the first symbol read, even if not mainline.
2976 (dbx_psymtab_to_symtab): symfile might be zero, cope.
2977 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
2978 (set_section_command): New command ("section xxx yyy" -- should
2979 be renamed to "set section xxx yyy" FIXME) which sets the
2980 base address of a section of the exec file, overriding the
2981 virtual address that BFD reports.
2983 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2985 * exec.c: Add add_syms_addr_command to exec_ops, so you can
2986 load symbols at any address while examining an exec file.
2988 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
2990 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
2991 for printing the float info is host-dependent, not
2992 target-dependent. FIXME.
2993 * i386-pinsn.c: Move #includes to top, remove useless ones.
2994 * i386-tdep.c: Don't bother including <.../reg.h> since we
2995 don't use it (and it doesn't exist on host systems).
2997 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
2998 Convert negative numbers properly.
2999 (ieee_test): Make numbers really random; fix format arg.
3001 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
3002 * core.c (core_detach): Unpush core_ops, which might not be on
3003 top. We used to just pop the top, which broke things. Don't
3004 need dont_repeat() any more.
3005 (core_file_command): Psst! Don't repeat it.
3006 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
3007 * expprint.c (print_subexp): Avoid switch fallthru on
3008 BINOP_ASSIGN_MODIFY, so we can print += and such.
3009 * frame.h: Fix typo.
3010 * inflow.c (kill_command): After killing inferior, print our
3011 current frame in the core file, if we have one.
3012 (generic_mourn_inferior): When inferior dies, either select
3013 the current frame (in the new target, e.g. core file), or
3014 set both the current and selected frames to NULL.
3016 Changes from Peter Schauer.
3018 * infptrace.c: Avoid <sys/ptrace.h> on USG.
3020 * Make all file names fit in 14 characters (sigh and damn!):
3021 mv hp300hpux-xdep.c hp300ux-xdep.c
3022 mv symmetry-xdep.c symm-xdep.c
3023 mv symmetry-tdep.c symm-tdep.c
3024 mv convex-opcode.h convx-opcode.h
3025 mv tm-vxworks960.h tm-vx960.h
3026 mv tm-vxworks68.h tm-vx68.h
3027 mv Makefile.srcdir Makefile.sdir
3028 mv gdb-int.texinfo gdbint.texinfo
3029 mv remote-sa.m68k.shar rem-m68k.shar
3030 mv remote-multi.shar rem-multi.shar
3031 * Makefile.dist, README, config.gdb, convex-pinsn.c,
3032 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
3033 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
3036 * command.c (user_info_1, user_info): New command for listing
3037 the user-defined commands.
3039 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
3041 * dbxread.c (really_free_pendings): Clear file_symbols
3042 and global_symbols after freeing them; otherwise, running
3043 this function twice (if it appears twice on the cleanup
3044 chain), we try to free things twice.
3046 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
3047 based on text_addr (the address of text in core), not on addr (the
3048 offset between text in the .o file and in core). This change
3049 is from Peter Schauer.
3051 * main.c: Define ALL_CLEANUPS as a cast of zero.
3052 (return_to_top_level): Use it.
3053 (main): Do all cleanups after each command run as part
3054 of the gdb startup sequence. Also do all cleanups before
3055 entering the command loop, and every time we exit the command
3056 loop and reenter. Before, the cleanups from the startup sequence
3057 were being left undone until the first error!
3058 (command_loop): Rename do_nothing cleanup to command_loop_marker
3059 so we can see it easily when examining the cleanup chain.
3060 (init_signals): Add another do_nothing for signal handling.
3061 (quit_command): Only try to kill target if it has execution.
3062 Problems in the target stack got us into a state where
3063 inferior_pid was nonzero but none of the targets had execution.
3064 In this state you couldn't exit gdb.
3066 * dbxread.c: Two changes from Peter Schauer.
3067 (echo_command): Fflush output after an echo command.
3068 (show_history): Pass all args to cmd_show_list.
3070 * utils.c (init_malloc): Call mtrace to turn on tracing
3071 if the environment variable MALLOC_TRACE is set to a file name.
3072 * mtrace.c: Add source file which provides a log of every malloc,
3073 free, and realloc to a trace file.
3074 * mtrace.awk: Add source file which analyzes the trace file.
3075 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
3076 (VERSION): Roll to 3.94.3.
3078 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
3079 (check_duplicates): Don't bother with watchpoints.
3080 (set_raw_breakpoint): Comment about danger of this routine.
3081 (watch_command): Parse and eval all args before calling
3084 * solib.c (find_solib): Avoid error in referencing memory to
3085 see if any more shared libraries have been added. This is
3086 particularly useful if the target has terminated. Bug reported
3089 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
3090 in bringing up 3.94.2 on the Sun-3.
3092 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
3093 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
3094 expression (in scope) before reenabling watchpoint.
3095 * signame.c (init_sigs): Add missing declaration of i, fix
3096 sys_siglist declaration.
3097 * source.c (list_command): Fixed range computation to use
3099 * stack.c (backtrace_command): Do not allow command if target has
3100 no stack, print informative error message.
3101 * target.c (target_command): Do not write into command line
3102 because this fails if the target command is used in a user defined
3103 command. [This change was enhanced by gnu to support any-
3104 unique-prefix matching on target names.]
3105 * valops.c (value_struct_elt): Avoid infinite loop on an
3106 erroneous attempt to print the member of function (try p main.p).
3108 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3110 * expread.y (name_no_typename): Avoid reduce/reduce errors
3111 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
3112 Since the GDB parser really doesn't use name_no_typename in a
3113 name-only context, the parser can't tell the diff between
3114 names and numbers here. Avoid allowing a name_no_typename
3115 to be a NAME_OR_*INT to resolve the conflict.
3117 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3119 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
3121 * valprint.c (val_print_fields): bitfield printing didn't handle
3122 byte order. Indirect through a few more fns to cope.
3124 * values.c (modify_field): also cope with byte order.
3126 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
3128 Cleanup for release 3.94.2:
3130 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
3131 include files. Roll version to 3.94.2.
3133 * coffread.c (init_stringtab): Read length into unsigned char
3134 array before swapping; don't assume 32-bit longs.
3136 * target.c (target_info): Don't bother with get_sym_file, just use
3137 the symfile global variable.
3138 * symtab.h, symfile.c (get_sym_file): Delete it.
3140 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
3141 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
3142 (read_type): Replace one more error() with complain().
3144 * mipsread.c (parse_partial_symbols): Replace printf with complain.
3146 * i960-tdep.c: Fix copyright attribution.
3148 * config.gdb: Quote all backquotes in doublequotes. You can
3149 quote me on that. BSD 4.4 shell found this one.
3151 * infptrace.c (throughout): The third argument to ptrace is an
3154 * infrun.c (wait_for_inferior): When program has terminated, we
3155 have to call target_terminal_ours before we pop that target off
3156 the stack (e.g. before a call to target_kill or
3157 target_mourn_inferior). This fixes problem where a program
3158 terminates, then GDB stops for (tty output) and you have to type
3159 "fg" to the shell to resume it. FIXME: This code for what to
3160 do after termination really should be in normal_stop instead.
3162 * gdbcore.h (read_memory_check): Change declaration; it changed
3165 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
3166 4.4 prereleases, this avoids a bug in their sgtty compatability
3168 * remote.c: Use terminal.h rather than hand-rolling the same.
3170 * signame.c, signame.h (psignal): Arg is unsigned, not int.
3171 * utils.c (strsave, strstr): Fix arg types.
3172 * valprint.c (val_print): lint
3174 MIPS symbol table support from Per Bothner:
3176 * symfile.c (symtab_fns): Remove initializer table that needs to
3177 be hacked for each new symbol file format supported.
3178 (add_symtab_fns): New function, chains symbol table
3179 handlers into the global list.
3180 (symfile_init): Search this list.
3181 * symfile.h: Add next pointer, declare add_symtab_fns.
3182 * coffread.c (_initialize_coffread): Call add_symtab_fns.
3183 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
3185 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
3186 symbol *). Thus, we no longer need the hack to trash
3187 pst->filename. Good, since that hack confused code in symfile.c!
3189 (reorder_symtabs, destroy_all_symtabs): Removed static
3190 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
3191 Instead, the latter now uses a temporary array (stack-allocated
3192 from an obstack, and then freed).
3194 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
3195 haven't been set in the outermost stBlock of a procedure. This was
3196 a problem with f77 binaries on Ultrix 4.?.
3198 (new_symtab, new_symbol, new_type): Continue changing code to use
3199 obstacks more and otherwise conform to dbxread internal style.
3200 Made the free_code of symtabs be free_linetable (as in dbxread)
3201 instead of free_contents. This implies memory leaks when reading
3202 a new symbol table, until the conversion is finished. Did change
3203 (struct symbol) and (struct type) to be allocated on the
3204 symbol_obstack. Blocks and blockvectors are among the things
3207 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
3208 tested much, but it solved one problem (reported by Meissner), and
3209 cleans up some other things. The problem happened when an
3210 included file contains actual code (functions) and not just
3211 definitions. The mips coff is a little inconvenient there, since
3212 it may cause a procedure to be mapped to the wrong psymtab.
3214 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
3215 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
3216 this will need work for the new core paradigm.
3218 Opcode patches from the net:
3220 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
3221 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
3222 missing altogether - they are added here. From Bruce Bauman.
3223 * mips-opcode.h: The low mask for C0 instructions was too small.
3224 From Garrett Lau. I modified the fix to check the entire 32-bit
3227 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
3230 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3232 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
3234 * dbxread.c (read_type): Pointer subtraction (value_sub in
3235 valarith.c) sometimes failed because the types of the
3236 pointers being subtracted were not identical.
3237 These differed because dbxread.c was allocating pointer types
3238 using dbx_alloc_type+smash_to_pointer_type instead of
3239 lookup_pointer_type. I failed to find a justification for the
3240 former, so I changed it to use the latter. Similarly, I
3241 replaced smash_to_function_type by lookup_function_type,
3242 and smash_to_reference_type by lookup_reference_type.
3244 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
3245 _initialize_mipsread): corresponding changes.
3247 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
3249 * source.c (mod_path): Do tilde_expand on each component of the path,
3250 rather than on the (list of) paths as a whole.
3251 (print_source_lines): Set first_line_listed in addition to
3252 current_source_symtab and current_source_line. If the source was
3253 not findable, after a "dir" command to fix the problem,
3254 a "list" would get the wrong lines.
3256 While I was there... (gnu):
3258 * dbxread.c (read_type): Change error to complaint.
3260 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3262 First attempt at detailed understanding of symbol table memory alloc.
3264 * dbxread.c (dbx_symfile_read): Free our string table if we
3265 aren't the mainline. Free the "info" struct since we're done with
3267 (init_psymbol_list): Free any previously allocated psymbol lists.
3268 (): FIXME: Should realloc-down the psymbol lists when done reading
3269 the main symbol file?
3271 * symmisc.c (free_symtab): Free fullname field too.
3273 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
3274 (REGISTER_ADDR): Make result type unsigned int.
3276 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
3277 define REGEX must also define REGEX1 (its dependency).
3279 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
3281 * tconfig/i960: No longer works, points you at vxworks960 or
3284 * xgdb.c, XGDB-README: Remove file. Users can get the much
3286 * Makefile.dist: Remove all trace of xgdb.
3288 * breakpoint.c (breakpoint_1): Pass demangle arg to
3289 print_address_symbolic.
3290 (clear_breakpoints): Remove unused function.
3291 (breakpoint_re_set_one): Guts of breakpoint_re_set.
3292 (breakpoint_re_set): Use catch_errors to do them all anyway.
3294 * gdb-int.texinfo (Host versus Target): Add section on what is
3295 a "host" feature versus what is a "target" feature.
3297 * infcmd.c (path_command, path_info): Handle the PATH variable
3298 (object search path) as conveniently as the source search path.
3299 * environ.c (set_in_environ): Set some vars in GDB's environment,
3300 in addition to the child's. PATH, G960BASE, G960BIN for starters.
3301 * source.c (mod_path): New function, from guts of
3302 directory_command, modifies a path. Used by path_command.
3303 (directory_command): Call it.
3304 * defs.h (strsave): Declare.
3306 * utils.c (sevenbit_strings): Add new printing option.
3307 (printchar): Use it.
3308 (strsave): Provide this handy helper routine.
3309 (set_width_command): Rename set_screen_width_command.
3310 (_initialize_utils): "set screen-width" => "set width";
3311 "set screen-height" => "set height"; add sevenbit-strings.
3313 * infcmd.c (do_registers_info): Print floating point registers
3314 in raw hex as well as float format, regardless of whether it is
3315 a "virtual" convertible register.
3316 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
3317 regs as a double, just in case it's being used that way.
3318 * values.c (unpack_long): Comment on array/function coercion.
3319 (unpack_double): Argument is in target byte order now. For
3320 integer arguments, just call unpack_long and float the result.
3321 * m68k-tdep.c: include defs.h for "const" handling.
3322 * remote-nindy.c: Use ieee-float stuff.
3323 (nindy_fetch_registers): Unpack double regs to host double, then
3325 (nindy_store_registers): Pack extendeds to host double, flip
3326 around by misusing unpack_double, send as target double.
3328 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
3329 zero, as when stopped at the first instruction of a process.
3331 * blockframe.c: Fix filename in comment (param.h => tm.h).
3332 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
3333 * tm-68k.h: Fix typos.
3335 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
3337 Changes from a bringup on the DEC Vax under Ultrix 4.0.
3339 * coredep.c (fetch_core_registers): Pass end-address of register
3340 section to register_addr as expected. Don't call supply_register
3341 if we'd just pass it garbage.
3343 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
3345 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
3347 * target.c (push_target, target_info): Cast enums to int for < or
3350 * stack.c (print_frame_info): Identify source file & line
3351 even if we can't print it.
3353 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
3355 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
3357 Clean up IEEE floating point support.
3359 * ieee-float.h: New file.
3360 * ieee-float.c: Write real routines to convert between host
3361 doubles and various target IEEE extendeds.
3362 * m68k-xdep.c: Eliminate assembler code for extended floats.
3363 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
3364 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
3365 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
3366 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
3367 double_to_ieee_extended.

3369 * m68k-tdep.c: Define ext_format_68881.
3370 * sparc-tdep.c: Define ext_format_sparc, though unused.
3371 * Makefile.dist (HFILES): Add ieee-float.h.
3372 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
3375 Obsolete the "coffstrip" program in favor of using BFD's strip.
3377 * nindy-share/coffstrip.c: Remove file.
3378 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
3379 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
3380 * tconfig/nindy960: Remove reference to coffstrip.o.
3382 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
3384 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3386 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
3387 * dbxread.c: Remove static symfile_bfd.
3388 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
3390 * inftarg.c (child_detach): Pop the child_ops vector if the
3391 detach is successful.
3392 * remote-nindy.c (nindy_create_inferior): Don't push a new
3393 nindy_ops since nindy uses the same one for execution and memory
3395 * core.c (core_ops): Use child_attach and child_create_inferior
3396 rather than default attach and create_inferior functions.
3398 Handle floating point registers in core files.
3400 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
3401 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
3402 This version untested since BFD doesn't yet support sun3 core
3404 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
3405 conventions. Fix comments and style. This version has not
3406 been compiled yet, since we have no HP inhouse.
3407 * core.c (get_core_registers): Look for two sections, ".reg"
3408 and ".reg2", and pass both to fetch_core_registers sequentially.
3410 Revise directory path yet again.
3412 * source.c (forget_cached_source_info): Not static any more.
3413 (init_source_path): New default source path is "$cdir:$cwd".
3414 (dir_command): Handle variable arguments ($cdir, $cwd).
3415 (source_info): Print "Compilation directory" rather than
3416 "Originally compiled in" to remind people of $cdir.
3417 (openp): If the path contains $cwd, use current directory.
3418 (open_source_file): If compilation directory is known, replace
3419 first $cdir in path with the compilation directory.
3420 (print_source_lines): Even if we can't print the lines, set the
3421 current symtab and line for future commands like "info source" or
3422 "breakpoint". Also, error message now contains the file name,
3423 line number, and file access error message.
3424 (_initialize_source): Fix help text to describe changes.
3425 * main.c (cd_command): Forget cached source info when we chdir.
3426 * utils.c (strstr): Add simple implementation.
3428 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
3430 * coffread.c (read_one_sym, init_linetable, init_stringtab):
3431 Byte-swap COFF symbol tables if necessary when reading them in.
3432 Use complain() to replace error message in one spot. Needs
3433 corresponding change in bfd/coff-code.h to make some symbol
3434 swapping routines non-static.
3436 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3438 Merge changes from Eirik Fuller, for UTek.
3440 * defs.h (errno): Add declaration.
3441 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
3442 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
3443 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
3444 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
3445 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
3446 declarations of errno.
3448 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
3450 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
3451 <rpc/rpc.h> and <rpc/types.h>.
3453 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
3455 * i960-tdep.c (examine_prologue): Add new argument limit,
3456 which stops the scan at the end of the prologue, or at the PC.
3457 This fixes a problem where it walks down into the code for the
3458 user's statements if that code looks like function prologues.
3459 Mark Fox and I have been bouncing this code back and forth, making
3460 small changes to it. Callers changed to match.
3462 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
3464 Cleanup for gdb-3.94 release final:
3466 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
3467 the .c files from vx-share and nindy-share, from the various
3468 macros, since they are not found via ALLDEPFILES.
3469 (SFILES): Add tm-i960.h.
3470 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
3471 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
3473 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
3474 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
3476 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
3478 * am29k-tdep.c: Add contribution line.
3479 (examine_prologue): Cache information about function prologues in
3480 the misc-function-vector to avoid lots of references over the
3481 serial line while examining instructions.
3483 * core.c (core_close): New function made from cleanup_core.
3485 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
3486 remote-vx.c, remote.c, target.c, target.h,
3487 Update target_ops vector to add attach, close, and load entries.
3488 Use add_syms_addr_command, not add_file_addr_command, for
3489 add_file. Break out close routine from existing code.
3491 * dbxread.c (really_free_pendings): Don't free pending_blocks;
3492 they are in an obstack.
3493 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
3495 (define_symbol): Add symbol type parameter; change callers;
3496 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
3497 it to influence the symbol class on the i960.
3498 (define_symbol): Swap LOC_CONST's into target byte order.
3500 * exec.c (exec_close): New function.
3501 (exec_file_command): Call it.
3503 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
3504 Fix byte order of frame pointer.
3505 (read_var_value): Result of 0 if var's value can't be found,
3506 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
3507 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
3508 (locate_var_value): Use read_var_value and use its lazy address
3509 as the location of the var's value. Lint.
3511 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
3514 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
3515 obsolete Intel versions in favor of vxgdb versions.
3516 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
3517 code dealing with byte order of values, which Intel did in host byte
3518 order rather than gdb-4's target byte order.
3519 (i960_frame_chain_valid): Move to nindy-tdep.c.
3520 (examine_prologue, skip_prologue, frame_find_saved_regs,
3521 frame_args_address, leafproc_return, saved_pc_after_call,
3522 pop_frame): Add vxgdb versions from Mark Fox.
3523 (examine_prologue, frame_struct_result_address): Add code
3524 to deal with the saved value of G13 (struct return address
3526 (frame_args_address): Modify Mark's version to prefer the
3527 saved value over the current value in the topmost frame.
3528 Cache result in the frame info to avoid performance hair in
3530 (print_fault): Add gdb960 code for printing faults.
3531 (_initialize_i960): Actually call check_host.
3533 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
3534 add stub routines. FIXME, these currently just return zero!
3536 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
3537 (attach_command): Call target_attach, not target_open, now.
3539 * infrun.c (normal_stop): Make global, not static, for vx_attach.
3540 (child_attach): Rename from child_open.
3541 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
3542 don't confuse it with a zero step_resume_break_address.
3544 * inftarg.c (child_detach): Eliminate inferior_pid test.
3545 (child_files_info): Clean up message a bit.
3546 (child_ops): Use child_attach, not child_open, to attach.
3548 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
3549 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
3550 findvar.c to here, since it depends on the contents of the
3551 shadow_contents of breakpoints, but keep if #if 0 since it is
3554 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
3557 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
3558 (ptype_command, display_command): Eliminate have_inferior_p and
3559 have_core_file_p in favor of target_has_stack or
3560 target_has_execution.
3561 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
3562 code for actually finding the values of arguments, though we still
3563 keep track of the maximum stack offset for use in printing unnamed
3564 arguments. Handle missing FRAME_ARGS_ADDRESS.
3566 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
3567 (struct nindy_regs): Define registers passed to/from nindy.
3568 (nindy_fetch_registers, nindy_store-registers): Translate between
3569 nindy and GDB formats for the registers.
3570 (dcache_init): Statically allocate the cache, since it was being
3571 allocated by a malloc that was never freed anyway.
3572 (nindy_create_inferior): Error, not core dump, if no exec file.
3573 (nindy_before_main_loop): Use target_load, not target_add_file.
3575 * remote-vx.c (net_load): Specify large timeout for load
3576 requests. Allow user to break out with INTERRUPT.
3577 (net_break): Remove useless code, clean up. Change callers.
3578 (parse-args, skip_white_space, find_white_space): Clean up arg
3579 parsing to cope with quoted strings.
3580 (net_wait, net_quit): Never call error, just return status.
3581 (vx_read_register, vx_write_register): Cleanup status checking.
3582 #ifdef the code based on which CPU we are using (960 or 68k),
3583 FIXME, this should be completely general but it isn't yet.
3584 (vx_xfer_memory, vx_resume): Cleanup status checking.
3585 (vx_run_files_info): Improve message.
3586 (vx_load_command): Renamed from vx_add_file_command. Allow load
3588 (net_ptrace): Remove unused routine.
3589 (vx_wait): Adopt code from vxgdb960 to cope with broken
3590 connections to target machine and prompt to disconnect. Remove
3591 debug printouts. Map some EVENT_'s to SIGnals.
3592 (add_symbol_stub, vx_open): Print names of object files we found,
3593 and "ok" if we read their symbols OK. Clarify output in general.
3594 (vx_attach, vx_detach, vx_kill): Add these commands.
3595 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
3596 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
3597 "info files" output, and create_inferior, since we already have
3600 * stack.c (frame_info): Replace Frame_unknown with 0.
3601 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
3602 (return_command): Pop until the PC matches as well as the FP,
3603 so it works even if the FP is shared with another function,
3604 as in "frameless" or "leaf" procedures.
3606 * symfile.c (load_command): renamed from add_file_target_command.
3607 (add_syms_addr_command): renamed from add_file_addr_command.
3608 (add_syms_command): Stub to call target_add_syms.
3609 (_initialize_symfile): Change command names and descriptions,
3610 add-file => add-syms, and load from alias to its own command.
3612 * target.c (kill_or_be_killed, maybe_kill_then_attach,
3613 maybe_kill_then_create_inferior): Default for attempts to start
3614 a process, if one is already running, is to ask about killing
3615 it and retry if yes.
3616 (upstack_create_inferior): #if-0 it, strata obsolete it.
3617 (push_target, unpush_target, pop_target): to_close() a target
3618 before unstacking it.
3619 (target_info): Renamed from target_files_info.
3620 (_initialize_targets): Rename "i files" as "i target", accessible
3623 * target.h: Improve comments about the target_ vectored routines.
3625 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
3626 Convert commenting style to standard GNU style.
3627 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
3628 (SKIP_PROLOGUE): No longer a no-op.
3629 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
3630 (*_REGNUM): Sort register numbers.
3631 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
3632 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
3633 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
3634 are now 10 byte extendeds, not 8 byte doubles.
3635 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
3636 for nindy versus vxworks targets. FIXME, this should possibly go
3637 in the target vector.
3638 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
3639 frame_saved_regs and arg pointer with each frame.
3640 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
3641 (FRAME_ARGS_ADDRESS): Use cached result.
3642 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
3643 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
3644 (PRINT_RAMDON_SIGNAL): Call print_fault.
3645 (POP_FRAME): Now works.
3647 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
3648 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
3649 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
3650 (ADDITIONAL_OPTION_HANDLER): use target_load, not
3653 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
3654 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
3656 * valarith.c (value_subscripted_rvalue): Avoid handling
3657 floats and doubles specially; it gave alignment errors. Lint.
3659 * valops.c (value_of_variable, value_of_this): Error if unknown
3662 * valprint.c (print_floating): Bcopy rather than pointer-deref,
3663 to avoid alignment problems.
3664 (value_print): Handle unknown value address.
3665 (cplus_val_print): Two args are ignored; remove them. Change caller.
3666 (val_print): Use unpack_long rather than pointer-deref.
3669 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
3670 to avoid alignment problems.
3671 (value_being_returned): Error if return value unknown.
3672 (set_return_value): Add bogosity warning, FIXME. *
3674 * TODO: A woman's work is never done.
3676 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
3677 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
3678 Add ieee-float.o to OBS.
3679 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
3680 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
3681 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
3683 Changes to generalize the VxWorks RPC protocol slightly, to handle
3684 i960 as well as 68000.
3686 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
3687 * vx-share/reg.h: Produce i960 regs #ifdef I80960
3688 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
3689 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
3690 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
3691 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
3692 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
3693 so they will move in target byte order rather than network
3694 byte order (happens to be the same).
3696 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
3698 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
3700 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
3703 Add contribution lines to various files, showing where they
3706 * breakpoint.c (break_insn, check_break_insn_size,
3707 read_memory_nobpt): Remove to mem-break.c.
3709 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
3712 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
3713 entry has bad register number. This change is not
3714 tested in this release, FIXME.
3716 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
3719 * value.h: Force value's contents field to be aligned to hold
3720 at least a double or a long long (if supported). This avoids
3721 doing bcopy's in and out of the contents field.
3723 (step_1): Avoid coredump under obscure circumstances when we
3726 * symtab.h (misc_info): Add field to misc function vector for
3727 any kind of cached information the target code desires. AMD
3728 29000 uses this to avoid repeating examine_function_prologue's.
3730 * coffread.c: Lint. Remove static symfile, read_section_header.
3731 core.c (have_core_file_p): Lint: remove.
3732 expprint.c (print_subexp): Lint.
3733 infptrace.c, valops.c, valprint.c: lint.
3735 Roll in changes from vxgdb-5.0.1:
3737 * symtab.h: Comment byte order of each address class. Add
3738 LOC_LOCAL_ARG for frame-relative args (960).
3739 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
3740 symtab.c, symmisc.c: ditto.
3742 * infrun.c (init_wait_for_inferior): Clear stop_signal.
3744 * remote.c (remote_resume): Error if resume with a signal.
3746 * symfile.c (prim_record_misc_function): Clear misc_info.
3747 (fill_in_vptr_fieldno): Check stub type of arg.
3749 * valops.c (value_cast): Avoid looking up names of types whose
3750 name we don't know, to prevent coredump. Sun CC produces typedef
3751 rtx and the name of *rtx is zero...
3753 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3755 Roll in changes from final AMD 29000 port (Tiemann).
3757 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
3758 for ../include/a.out.encap.h. This might not work now that BFD
3759 is separately compiled. Instead, BFD support for encap will have
3760 to translate machine type 29k into the right COFF_MAGIC.
3762 * infcmd.c: Remove references to inferior_pid that aren't used
3763 in actual ptrace calls; use target_has_execution, etc.
3764 (have_inferior_p): Remove function.
3765 (program_info): Print target info rather than "process number";
3766 avoid gratuitous messages unless from_tty.
3767 (run_stack_dummy, finish_command): Set proceed_to_finish.
3768 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
3769 main.c: Lint. Lose have_inferior_p().
3770 inferior.h (have_inferior_p): Remove, lint.
3771 (proceed_to_finish): Add flag to ask that all regs be saved
3772 by normal_stop, for the few commands that need it, speeding up
3773 serial I/O. Add comments to stop_registers.
3775 * remote-eb.c: Remove newline from breakpoint message we grep
3776 for. Never time out when running the user program.
3780 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3782 Roll in changes from vxgdb-5.0.1:
3784 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
3785 symbol in its raw form, we are processing an unlinked ".o" file.
3786 See if the target environment has assigned it an address, using
3787 target_lookup_symbol (VxWorks does), and enter it into the symtab
3790 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
3791 68k versions for a simpler version that assumes zero FP at bottom.
3792 Fixes bug of truncated stack reports.
3794 * target.h (target_lookup_symbol): Define this routine's args
3795 and result, finally.
3797 * target.c (nosymbol): Default routine for target_lookup_symbol.
3798 (target_default): Default lookup_symbol and call_function too.
3799 (files_info): Only print has_all_memory warning if a non-dummy
3802 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
3803 vx_convert_from_virtual): If target does not have floating point,
3804 zero register "values", and avoid doing cross-net conversions.
3805 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
3806 (vx_open): Rearrange code that attaches to target and reads
3807 symbols for all loaded modules, to work if some of the modules
3808 are not accessible. Add symbol_stub() and add_symbol_stub()
3809 as callbacks from catch_errors(). Allow connect attempt to be
3810 interrupted painlessly with ^C (FIXME, there are still some bugs
3811 if the interrupt happens during symbol reading.). Print
3812 final message with puts_filtered, since symbol messages are
3817 * main.c (catch_errors): Only print errstring if non-null.
3818 (command_loop): Avoid an ioctl per command to test ISATTY.
3820 * remote-vx.c (net_load): make static; avoid sophomoric msg.
3821 (vx_xfer_memory): Return correct result!
3822 (vx_files_info): Indicate whether target has float or not.
3823 (vx_lookup_symbol): Complain, not error, if target gone.
3824 (vx_open): Print "Connected" msg before disabling immediate-quit.
3825 [FIXME: lookup_symbol and vx_open changes need testing.]
3827 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
3828 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
3829 contributor lines and update copyrights to 1991.
3831 Changes from an attempted H-PUX host port:
3833 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
3834 defines PT_ATTACH and PT_DETACH but not PT_KILL.
3835 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
3836 * remote-vx.c: include <sys/time.h> for HPUX.
3837 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
3838 "core_file_command" routine to BFD regime. May not work yet.
3840 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
3842 * xgdb.c: Replace X10 version with some VJ version.
3843 (FIXME: Its copyright assignment is not on record.)
3844 * xgdb.c: Update include files to X11R4 (Xaw crud).
3845 (xgdb_display_source, create_text_widget): fix call to
3846 get_filename_and_charpos. Rewack source window stuff for X11R4
3847 (gleaned from include files, and "nm's" of binary libraries, since
3848 I had no doc available).
3849 (append_selection, append_selection_word): Disable with FIXME
3850 since R4 changed interface here.
3851 (create_buttons): Add back the old set of buttons.
3852 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
3854 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
3855 Roll VERSION to 3.94 (not yet final though).
3857 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3859 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
3860 obstack_int_grow, obstack_int_grow_fast): Eliminate
3861 cast on left of assignment, which gives MIPS cc fits and is
3864 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
3865 F_ALIAS. Use printf, not fprintf, when not passing a file
3867 (compare_opcodes): Check that identical instructions have
3868 identical opcodes, complain otherwise.
3870 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
3871 was reported by Roland McGrath.
3872 (unimp): Only match if exactly zero instruction. (Roland)
3873 (branches and traps): Generate all variations of these
3874 instructions with macros, based on a single call that defines
3875 each condition name and its binary representation.
3876 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
3878 * valprint.c (val_print_fields): Take, and use, format parameter.
3879 This means that "p/x struct" again prints the elements in the
3880 desired format. Changed callers.
3882 * stack.c (frame_info): Use filtered output, and indicate wrap
3883 points. Remove kludgy formatting designed to avoid line wrap.
3885 * utils.c (wrap_here): If the line is already full (because
3886 we had printed a long indent or long wrapped string), do an
3887 immediate newline-and-indent.
3889 * m68k-pinsn.c (print_insn_arg): Bugfix from
3890 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
3891 instruction is incorrectly disassembled as bkpt #8.
3893 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
3894 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
3895 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
3896 and then will dump core (sometimes). I traced it back to an
3897 uninitialized symfile_name in psymtab_to_symtab.
3898 (const_vol_complaint): Add quotes to message.
3899 (define_symbol): Only believe line number if gcc_compiled.
3900 Avoid allocating symbol if we will not return it.
3902 Add target strata support so that newly established targets go
3903 into their right place in the target stack (e.g. a new exec file
3904 doesn't wipe out the ability to access the running process).
3906 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
3907 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
3908 and initialize it properly in all the targets.
3910 * target.h: Document strata. Change return type of push_target.
3912 * target.c (nomemory): new function for dummy memory access.
3913 (tcomplain): Rename complain, now also used in symfile.c.
3914 (push_target): Push targets within strata. New return value shows
3915 whether new target is on top of stack or not. Always keep dummy
3917 (target_files_info): Ignore dummy target.
3919 * core.c (core_open): Warn user, and skip accessing file, if the
3920 core target is not the topmost target in the stack.
3921 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
3924 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
3925 target_ops, it doesn't belong there since we have no regs there.
3926 Change name of target from machine => memory to clarify.
3928 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
3930 * Freeze version 3.93 for release.
3932 * Makefile.dist: Handle vx-share and nindy-share subdirs
3933 properly when building gdb.tar.Z.
3935 * symtab.c: lint; add no_symtab_msg to consolidate the messages
3936 printed in various places, so I could change just one copy.
3938 * dbxread.c, coffread.c: Change references to bfd->iostream
3939 to cast to FILE *, now that BFD avoids needing types defined
3940 in other header files.
3942 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3944 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
3945 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
3946 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
3947 (actually gcc -Wall).
3949 * dbxread.c: Remove first_global_sym, last_global_sym, since
3950 they are never referenced.
3952 * defs.h (baud_rate): Declare.
3953 main.c: Define it, and add the -b option to set it.
3955 * gdb-int.texinfo: Add text on how to define a new host or target
3956 architecture, prompted by Per Bothner's questions about MIPS
3959 * gdb.texinfo: Document "complaints". Change doc of -q since
3960 gdb no longer prints the copyright and blurb if you specify a file
3961 name to be debugged (just like Emacs). Add doc for Nindy-specific
3962 command line flags for specifying target serial port and such.
3963 Update copyright to 1991.
3965 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
3966 has taken over for us the job of ripping up executable files. The
3967 crud caused Per Bothner's port to not compile.
3969 * infrun.c (normal_stop): Avoid printing "Program exited
3970 normally" if we are in batch mode. This allows a GDB which
3971 executes a program on a target system, to behave like a Unix
3972 command (input from stdin, output to stdout, no extraneous
3975 * main.c (main): Allow additional machine-dependent command line
3976 options to be specified with the ADDITIONAL_OPTIONS,
3977 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
3978 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
3979 processing to occur just before the main loop with
3980 BEFORE_MAIN_LOOP_HOOK.
3981 (main): If a "core file" argument is specified, and it is not a
3982 core file, try it as a process ID to attach.
3983 (symbol_completion_function): Attempt to cope with
3984 "show screen-" TAB, not very successfully. This needs more work,
3986 (batch_file): New function, returns whether we are reading
3987 commands from an interactive tty on stdin, or from somewhere else.
3988 Called by normal_stop since it doesn't get from_tty passed down
3989 to it like many commands do.
3991 * remote-nindy.c: Handle command line options for nindy
3993 (nindy_before_main_loop): Prompt user for tty name if they
3994 don't specify it before getting to the interactive command loop.
3996 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
3997 and -r command line options. Also add hook before main loop
3998 to make it easy to specify a tty.
4000 * TODO: More things to do, one done.
4002 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
4004 * dbxread.c: Make complaint() calls pass pointer, not struct.
4005 Add complaints about badly formatted C++ type information
4006 (const/volatile indicator, and parse errors resulting in
4007 error_type). Fix C++ virtual member fn comment.
4008 (read_struct_type): Avoid bumping pointer if we got a parse
4009 error; this prevents our walking beyond the end of a string.
4010 Terminate loop on null char as well as semicolon.
4011 (process_one_symbol): Fix the LBRAC fix so that it uses the
4012 last previous SLINE, FUN, or SO record's PC address. C++ debug
4013 symbols did not have SLINE records in a useful order compared
4014 to the LBRAC records.
4015 (define_symbol): Handle "catch" records.
4017 * symtab.c (check_stub_type): Added new complain
4018 `stub_noname_complain' and added a consistency check to
4019 keep the debugger from crashing when finishing from an
4020 exception frame. A real fix will be needed later.
4022 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
4024 * infcmd.c (attach_command): Make global.
4026 * Makefile.dist (REMOTE_OBS): Make these compile by default,
4027 but make them easy to comment out. Perhaps later they should
4028 be enabled by what CPU you configure for? FIXME.
4029 (VERSION): Roll to 3.93.
4030 (pinsn.o): Remove rule for obsolete file.
4031 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
4033 Run down a problem that manifested by printing the wrong function
4034 name in stack traces of read_ofile_symtab. Turned out that the
4035 problem was the SunOS 4.1.1 (and previous) C compiler outputs
4036 the LBRAC symbol with an address in the *data* segment, which
4037 blew our binary search through the blocks.
4039 * dbxread.c: Use the complain() facility consistently to bitch
4040 about problems in the symbol file we are reading.
4041 (finish_block): Add code to check the nesting of the blocks;
4042 complain and Procrust them to fit if wrong.
4043 (make_blockvector): Check the order of the blocks, complain
4044 [but don't cope] if wrong.
4045 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
4046 symbols to be sure their PC value is greater than the last SLINE
4047 (line number) symbol we've seen, complaining and adopting the
4048 SLINE PC value if wrong.
4050 * symfile.h (struct complaint, complaint_root, complain,
4051 clear_complaints): Add.
4052 * symfile.c (complain, complaint_root, clear_complaints): Add
4053 facility to deal with non-fatal complaints and to regularize their
4055 (symbol_file_add): Clear complaint counters to allow new complaints.
4056 (initialize_symfile): Add 'set complaints' and 'show complaints'.
4058 * dbxread.c (dbx_symfile_read): Remember the address and size
4059 of the string table for the main symbol file, so we won't read it
4061 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
4062 to avoid reading the string table yet again. Lint.
4063 (throughout): Improve filtered output, including word wrap.
4064 (read_range_type): Improve Bothner's fix to handle other types too.
4066 * utils.c: Improve line wrap implementation. Handle unlimited
4067 width by making chars_per_line unsigned.
4068 (puts_filtered): New, easy, function.
4070 * defs.h (puts_filtered): add.
4072 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
4073 call the identical sort_symtab_syms() in symfile.c instead.
4075 * expread.y: Suggest the `file' command rather than `symbol-file'.
4077 * command.h (enum var_types): Add zinteger for seroable
4079 * command.c (do_setshow_command): Handle var_zinteger. Restructure
4080 nested if's into a switch.
4082 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
4083 we did not stop because of a breakpoint (it must have been for
4084 some other reason, like a "stepi"), so don't print anything.
4086 * symtab.c: Include <sys/types.h> all the time. Now that BFD
4087 doesn't include <sys/types.h>, old SunOS's require it for
4090 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
4092 A test port of gdb-3.92.6 to the Sony NEWS.
4095 Don't normally link in remote- or vx stuff.
4096 Some of it doesn't compile, and it wastes space for 99% of the users.
4097 Remove reference to no-longer-used HAVE_VPRINTF.
4098 Fixed BFD_DEP typo to BFD_DIR.
4100 Fix cast in arg to bfd_h_getlong.
4101 Make char *prefix be const.
4102 Fix how certain range types are mapped into builtin unsigned int types.
4104 Remove 2 #includes. They cause errors (on Sony, at least),
4105 and aren't needed (they wern't in earlier versions).
4107 print_address_symbolic should never demangle labels
4108 (since it prints *assembler-level* labels).
4110 [This was superseded by the change to printcmd below.]
4113 Add some "volatile" return types to avoid warnings.
4114 If MISSING_VPRINTF add vprintf function and not just macro
4115 (since vprintf is used in printcmd.c).
4117 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
4118 (The latter isn't grokked by some PCC-based compilers.)
4120 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
4122 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
4123 * nindy-share/coffstrip.c
4124 Added some forward declarations (otherwise, gcc complains
4125 about implicit extern redefined as static).
4127 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
4129 Changes inspired by Per Bothner:
4130 * printcmd.c (print_address_symbolic): Take additional parameter
4131 specifying whether to demangle.
4132 (print_address): Pass in asm_demangle to control demangling.
4133 (print_address_demangle): New fn, takes explicit arg to control
4135 * utils.c: Add new vars demangle and asm_demangle, and let them
4137 (fputs_demangled): If !demangle, just print the argument.
4138 (fprint_symbol): If !demangle, just print raw symbol.
4139 * valprint.c (val_print): Call print_address_demangle rather than
4140 print_address, to cause demangling to depend on the global
4141 rather than assembler-level demangling setting.
4142 * WHATS.NEW, gdb.texinfo: Document.
4144 * main.c (show_command): Show all settings if no arg.
4145 (initialize_main): Make "info set" the same as naked "show".
4146 * command.c (cmd_show_list): Handle prefix commands in the
4147 list, and print the name of the setting as well as its English
4148 description and value.
4150 Allow gdb functions to specify where a line should wrap if it
4151 exceeds the size of a terminal line. Use it to make the output
4153 * utils.c (set_screen_width_command): New fn, mallocs a buffer
4154 of the right size when screen width changes.
4155 (set_screensize_command, screensize_info): Remove #if 0'd fns.
4156 (wrap_here): New fn, indicates a point in the output where we
4157 should wrap the line rather than just letting it overflow at a
4159 (fputs_filtered): Implement wrapping.
4160 (n_spaces): New fn, returns a pointer to N spaces.
4161 (print_spaces_filtered): Use n_spaces.
4162 * defs.h (n_spaces): Declare.
4163 * stack.c (print_frame_info): Wrap with 4-space indent after
4164 fn name and before filename and line number.
4165 * printcmd.c (print_frame_args): Wrap with 4-space indent
4166 before each argument name is printed.
4167 * valprint.c (value_print): Wrap with no indentation before
4169 (val_print_fields): Wrap with indentation relative to nesting
4170 level before each field name.
4171 (val_print): Wrap with nesting indentation before array elements.
4172 * command.c (do_setshow_command): Avoid extra newlines,
4173 wrap with 4-space indent around values printed, end with period.
4174 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
4176 * breakpoint.c (breakpoint_1): Implement addressprint for
4177 "info breakpoints" display. Change file name and line number
4178 format to " at file:nnn" rather than " (file line nnn)".
4179 * gdb.texinfo: Document.
4182 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4184 Frozen for gdb-3.92.6 release.
4186 README, WHATS.NEW: Update for 3.92.6 release.
4188 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
4189 coffread.o from configs since it is now built by default.
4190 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
4191 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
4192 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
4193 from configs since it is now built by default.
4195 Makefile.dist: Update for release 3.92.6. Handle files that
4196 have been moved to ../include, ../getopt, or ../bfd. Add
4197 saber.suppress and tests directory. Add config.status to
4198 the release (it will say "none").
4200 coredep.c: Minor formatting fixes.
4202 These changes were made in early December but only checked in now:
4203 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
4204 nindy-share/nindy.c: lint
4205 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
4206 register values coming back from the target; we store values
4207 in target byte order everywhere.
4209 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
4211 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
4213 * valprint.c (cplus_val_print, val_print_fields): New functions,
4214 which print C++ objects. They conspire to avoid printing a
4215 virtual base class more than once, following all the twists and
4216 turns of C++ virtual base rules.
4217 (val_print): Call the above rather than do it by hand.
4219 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
4220 symbol file, not for added files like shared libs. This really
4221 needs to be generalized to a timestamp per file.
4223 * core.c (cleanup_core): Avoid coredump if no core file.
4225 * config.gdb: Accept -host or -target in place of +host or
4228 * coffread.c (find_linenos): Avoid desupported BFD interface
4229 to line numbers. We still read them manually rather than using
4230 BFD's "generic" features.
4232 * gdbrc.tex, threecol.tex: Add GDB reference card and its
4234 Makefile.dist: Add refcard to OTHERS list for creating tar files.
4236 * Makefile.dist: Eliminate use of $< in explicit targets.
4238 * readline/Makefile: Use $< rather than $*.c, which does not
4239 include the VPATH in GNU Make.
4241 * tconfig/i960-bout, tconfig/i960-coff: These are identical
4242 copies of tconfig/i960, added for global configuration
4243 compatability. All i960 versions can read both coff and b.out.
4245 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
4246 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
4249 * TODO: Think of more things to do.
4251 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
4253 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
4254 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
4255 64-bit float conversion.
4257 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
4258 equivalent to sun?os4 so global config works.
4260 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
4262 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
4264 * main.c: Only declare linesize once; declare pagesize not at
4265 all, since it is never used.
4266 (main): Clear newly allocated line before it is used.
4268 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
4270 Further stabilization for the Intel 960.
4272 * Makefile.dist: Parameterize the location of the "include"
4273 and "bfd" directories, as well as "getopt". Add symfile.c.
4274 Link in both dbxread and coffread. Fix up "make depend" to
4275 rewack the locations of include, bfd, and getopt in its output.
4277 * README: Document moving include files, improve some of
4280 * coffread.c: Move common code out to symfile.c. Change
4281 symbol_file_command style interface to use new *_symfile_init
4282 and *_symfile_read interface under BFD. Use BFD internal
4283 info to locate line table, symbols, etc.
4285 * core.c (core_fetch_registers): Rename to get_core_registers
4286 to avoid confusion with fetch_core_registers.
4287 (register_addr): Move to coredep.c, which is already machine
4288 dependent. This leaves core.c pretty clean of dependencies.
4290 * coredep.c (register_addr): Accept this routine from core.c.
4292 * dbxread.c: Move common code (with coffread.c, etc) into new
4293 symfile.c. Each psymtab now contains a pointer to the
4294 format-dependent function that knows how to read it in. Make
4296 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
4297 (process_one_symbol): Add code to complain about a "compiler bug
4298 we muzzle here", if we actually see it.
4300 * eval.c (evaluate_subexp): Insert missing "break" statements
4301 in code that determines whether a variable is an lvalue in
4302 memory, register, or whatever. I detected this via a compiler
4303 bug in which it *almost* mashed out the whole switch statement.
4305 * gdb-int.texinfo: Add minor sections on configuring gdb for
4306 release, and about the README file.
4308 * infcmd.c (registers_info): Fix formatting somewhat. Still
4309 not as pretty as before, but it handles byte swapping.
4311 * remote-nindy.c: If data cache routines are interrupted while
4312 waiting for the remote end, be sure that any uninitialized cache
4313 blocks are on the free list, not on the valid list!
4315 * symfile.h: Flesh out this header file with all the various
4316 routines and variables that have been merged in from dbxread.c
4317 coffread.c, and symtab.c to symfile.c.
4319 * symfile.c: New file, containing code common to dbxread.c,
4320 coffread.c, and some code from symtab.c. All generic code for
4321 reading symbol files should be in here now.
4322 (unrecord_misc_function): Remove unused function.
4324 * symtab.h: Remove file-reading things to symfile.h.
4326 * symtab.c: Remove file-reading things to symfile.c.
4328 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
4329 to decode i960 fault types.
4331 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
4332 target.c: Change type of the "resume" function from int to void,
4333 since its result was never used.
4335 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
4337 * main.c: Replace "stupid" with "caution"; you now "set caution
4340 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
4342 * infcmd.c (do_registers_info): Call val_print to deal with the
4343 byte order of the registers being printed. FIXME, this makes
4344 the formatting of the output uglier.
4346 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
4347 defined, call it for signals the debugger doesn't itself use.
4348 The i960 uses this for more detailed fault information.
4350 * remote.c (remote_open): If arg is null, print help rather than
4353 * sparc-xdep.c (register_valid): Avoid declaring size, since
4354 various modules will think of various sizes depending on the
4355 architecture of their tm-file. FIXME, we need protection against
4356 actually entering one of those modules, which would clobber
4357 storage if not for the target architecture compiled into gdb.
4359 * stack.c (up_command, down_command): Always print the frame
4361 (up_silently_command, down_silently_command): New commands
4364 * i960-pinsn.c (reg), i960-tdep.c: Lint.
4366 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
4367 more parameters than it used to.
4369 * findvar.c (registers): Increase slop to 256 bytes, which should
4370 protect us against even most RISC machines with large register
4372 (locate_var_value): Move declaration inside related ifdef.
4374 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
4375 throughout, to avoid throwing away buffered input from the board.
4376 (nindy_wait): Supply_register takes addr_of_value, not value.
4377 (i960_print_fault): Renamed from i80960_fault.
4378 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
4379 (nindy_store_registers): Avoid regs_changed stuff, just stuff
4381 (nindy_create_inferior): Don't bother to write PC_REGNUM since
4382 we can set the PC in the call to proceed(). Unpush nindy_ops
4383 before pushing it on top, to avoid message to user. Eliminate
4384 commentary from Unix machines that just misleads here.
4385 (reset_command): Fix error message to suggest target command.
4387 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
4389 Release 3.92.5 as frozen.
4391 Stabilize the merged release...with help from lint, Saber C,
4394 Everywhere: Add include files needed to declare return types
4395 of functions called.
4397 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
4399 * breakpoint.h: Add undeclared breakpoint functions, and some
4400 functions for display handling since I couldn't think of a better
4403 * breakpoint.c (insert_breakpoints): Make code for disabling
4404 shared library bkpts more likely to work. It's used when we
4405 rerun a program and stop before the shared library has been
4407 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
4408 cast from pointer, so it squeezes through catch_errors.
4409 (bpstat_stop_status): Fix logic broken some time ago. We now
4410 always create a bpstat if the stop address matches a breakpoint,
4411 even if we don't stop there -- just like the old code used to do
4412 before I got my fingers into it (sigh).
4413 (breakpoint_1): Print "ignore count" after "stop only if"
4414 condition, since that's how it actually works.
4415 (mention): Handle watchpoints as well as breakpoints.
4416 (watch_command): use set_raw_breakpoint and mention to do most
4417 of the work (and initialize all the fields!). Only pass one
4418 arg to parse_c_expression, since that's all it takes.
4420 * command.c (not_just_help_class_command): Rename arg to args
4421 since we ignore "unused argument" warnings on vars named "args".
4422 inflow.c (child_terminal_info): ditto.
4423 infptrace.c (kill_inferior): ditto
4424 main.c (catch_errors, version_info, quit_command, pwd_command,
4425 source_command, dump_me_command, editing_info,
4426 set_history_size_command, set_history, show_history,
4428 stack.c (locals_info): ditto
4429 target.c (target_files_info): ditto
4430 valprint.c (set_input_radix, set_output_radix): ditto
4432 * core.c: Remove old variables for handling core and exec file
4433 sections (data_start, data_end, stack_start, stack_end,
4434 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
4435 text_end, exec_data_start, exec_data_end, text_offset,
4436 exec_data_offset, data_offset, stack_offset). They're
4437 superseded the more general build_section_table and
4439 (get_exec_file): Mention the `file' command.
4440 (read_memory_check): Rename to memory_error, and only call it
4441 in the case of an actual error.
4442 (read_memory, write_memory): call memory_error.
4443 (core_fetch_registers): Register section name is ".reg".
4445 coredep.c: Remove a bunch of crud now that all this file does
4446 is pull the registers out of a core file.
4447 (fetch_core_registers): Rewrite to actually work, I hope.
4449 dbxread.c: Use a.out.gnu.h, not system a.out, now.
4450 Replace index() with strchr(). Remove all the pre-BFD macro
4451 definitions for accessing the symbol file.
4452 (struct dbx_symfile_info): Encapsulate the information that
4453 dbx_symfile_init needs to pass to dbx_symfile_read in this
4456 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
4457 dbx_symfile_discard): Rearrange symbol file reading to divide
4458 the format-specific part from the format-independent part,
4459 leaving the format-independent part such as file name expansion
4460 and opening in symtab.c. This replaces
4461 partial_symbol_file_open and partial_symbol_file_read.
4462 Symbol_file_read, add_file, add_file_target_command,
4463 add_file_addr_command move to symtab.c. Pass an explicit
4464 "mainline" flag for when reading the main symbol table, rather
4465 than relying on the offset address to be zero or nonzero.
4467 (dbx_symfile_read): Don't allow void *'s to be printed as
4469 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
4470 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
4471 macro" debug version really work.
4472 (read_dbx_symtab): Remove unref'd parameter inclink.
4473 Avoid swapping N_SLINE symbols, for speed.
4474 Merge N_TEXT!N_EXT case with the other external symbol
4475 definitions' case. Add comments.
4476 (start_psymtab): Allocate the symfile name in the psymtab on
4477 the psymbol_obstack, rather than using the caller's storage.
4478 (end_psymtab): Only allocate a dependencies list if there are
4480 (psymtab_to_symtab_2): Use BFD when reopening file to read
4481 its symbols for real.
4482 (read_struct_type): Add FIXME comments where it needs work
4484 (read_huge_number): Add FIXME about overflows.
4485 (read_range_type): Add FIXME about comparing a long to 1<<32.
4487 * coffread.c: Minor changes to move things closer to the new
4488 regime with symtab.c and dbxread.c Major work is still needed
4491 * exec.c (exec_file_command): Remove old variables (see core.c
4493 (xfer_memory): If memory transfer is right at the end of a
4494 section, don't lose.
4496 * findvar.c (get_saved_register): If value is in a real
4497 register, LVAL is lval_register, not lval_memory.
4499 frame.h: Declare print_sel_frame and record_selected_frame.
4501 gdb-int.texinfo: New file, for GDB internals documentation.
4502 Very simple, unformatted doc of cleanups is there for now.
4504 gdbcore.h: Remove obsolete variables that described a.out
4505 section addresses and offsets. (See core.c above.)
4506 Declare fetch_core_registers and registers_fetched.
4508 getopt.c: Declare char *alloca(); even on SPARC.
4510 infcmd.c (run_command): Call target_kill rather than
4512 (step_command, next_command, stepi_command, nexti_command):
4513 Declare from_tty parameter even though we don't use it.
4514 (run_stack_dummy): argument BUFFER is a char array, not
4515 a pointer to REGISTER_TYPE.
4516 (finish_command): using_struct_return needed a value *,
4517 not a struct symbol *.
4519 * infptrace.c (child_xfer_memory): To avoid dependency on
4520 where sections are in memory, try PT_WRITE_D and if that fails,
4521 try PT_WRITE_I. Most Unixes don't care which you use.
4523 * infrun.c (step_resume_break_shadow): Change to array to
4524 match other breakpoint shadow storage.
4525 (clear_proceed_status): Pass address of bpstat to
4526 bpstat_clear, not the bpstat itself.
4527 (child_create_inferior): FIXME comment about if the child
4529 (start_inferior): Remove old function.
4530 (child_open): Use target_kill rather than kill_inferior.
4531 (wait_for_inferior): Ditto.
4532 (insert_step_breakpoint, remote_step_breakpoint): Use
4533 new step_resume_break_shadow.
4535 * inftarg.c (child_wait): If all child processes die,
4536 pretend that the one being waited for exited with signal 42.
4538 * main.c (command_line_input): When scanning for comments,
4539 don't coredump on unclosed quotes.
4540 (quit_command): Use target_kill rther than kill_inferior.
4541 (_initialize_main): Rename class_user from "user" to
4544 * printcmd.c (print_command_1): Initialize "fmt" if no format
4545 is specified by the user.
4546 (print_frame_args): Only add to args_printed if we are
4547 actually fetching args from the stack (avoiding undefined
4549 (_initialize_printcmd): Remove bogus \{ from string.
4551 * remote-eb.c (eb_open): Avoid coredump on no argument.
4553 * remote-nindy.c: Bring out of Intel environment into new
4554 target environment. Remove all conditional compilation on
4555 I80960. Massive hacking throughout.
4556 (nindy_xfer_inferior_memory): New routine stolen from
4558 (nindy_create_inferior): New routine pieced together, probably
4559 not quite working yet.
4560 (nindy_ops): New target_ops struct for nindy.
4562 * remote-vx.c: Use write_memory rather than target_write_memory
4563 to get error checking.
4564 (vx_add_file_command, vx_open): Use symbol_file_add rather than
4566 (vx_create_inferior): Use target_terminal_ours...
4568 * signame.c (_initialize_signame): Always initialize, since
4569 we need the table for things other than psignal.
4571 * solib.c (solib_add): Use symbol_file_add, not add_file.
4572 (solib_address): Return boolean result rather than struct
4573 pointer which nobody else knows the type of.
4575 * sparc-tdep.c, valops.c: Use write_memory rather than
4576 target_write_memory, to get error checking.
4578 * stack.c (locals_info, catch_info, args_info,
4579 get_selected_block, frame_command, up_command): Use
4580 target_has_stack, rather than have_inferior_p or
4583 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
4585 * symfile.h: New file, defining the interface between the
4586 generic and object-file-specific symbol reading code.
4588 * symtab.c: Move generic symbol-reading interface to symtab.c,
4589 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
4590 table to map BFD targets to symbol-reading modules in GDB.
4591 Change index to strchr.
4592 (lookup_struct_elt_type): Use error() rather than hand-made
4593 simulations thereof.
4594 (lookup_partial_symbol): Speedup slightly when length == 0.
4595 (symbol_file_add): New function.
4596 (symbol_file_command): Call it.
4597 (symfile_open, symfile_init): New function.
4598 (add_file_target_command, add_file_addr_command): moved from
4601 * target.c (target_command): use target_kill.
4603 * target.h (target_files_info): Don't declare, never called
4606 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
4607 files to determine stack end address.
4609 * valarith.c (value_x_binop, value_x_unop): Change error message
4610 to be more useful. Pass proper argument to value_struct_elt.
4612 * valops.c (value_assign): FIXME comment that long long
4613 bitfields will break here.
4615 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
4616 Update `make saber_gdb' to work better.
4618 * TODO: A woman's work is never done.
4620 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
4621 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
4622 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
4623 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
4624 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
4625 valops.c, valprint.c, exec.c: Lint.
4628 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
4630 Continuing Intel 960 port merge of GDB.
4632 * Makefile.dist: Merge i960 "nindy-share" files. Rename
4633 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
4634 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
4635 Wack over "make depend" so it handles files in subdirectories
4636 vx-share, nindy-share, bfd, and in the current directory.
4638 * blockframe.c (get_prev_frame_info): Remove fatal error
4639 if stack not defined.
4641 * core.c (core_open, core_detach): New functions that handle
4642 the old "core-file" command as "target core" and "detach" instead.
4643 (core_file_command): Call them.
4644 (core_xfer_memory): Use common routine xfer_memory.
4646 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
4647 dbxread now uses bfd for everything but symbol reading itself.
4648 BFD internals are used to drag out the relevant file offsets.
4649 (partial_symbol_file_open): Change args all around for BFD.
4651 * symtab.c: Rename "value" to "val" everywhere, so we can
4653 (symbol_file_command): New command, moved from dbxread.c
4654 and coffread.c. It uses BFD to read the file, then vectors
4655 based on its type, to dbx or coff symbol readers.
4656 * symtab.h: Extern a few vars for symbol_file_command.
4658 * target.h: Breakpoint takes a char * save area, not a char **.
4660 * valprint.c (val_print): When unpacking bitfields, offset
4661 the address in gdb of the value, if it is declared with a shorter
4662 type. Remove the last "runtime kludge test" of host byte order.
4664 * utils.c: Remove old my_bfd_read routine.
4666 * stack.c (frame_info): Use target_has_stack. Print program counter
4667 register's actual name rather than "pc", since it's called the
4668 "ip" (instruction pointer) on the i960 (sigh).
4670 * target.c (target_command): Add command for selecting a target
4671 type and calling its open routine. This is used for initiating
4672 communication with a particular target, in a generic way.
4674 * tm-i960.h: Update for modern gdb. Remove semicolons from
4675 various macros. Handle reading struct return convention, and
4676 error-out attempts to return structs with the "return" command.
4677 Be sure gdb doesn't think we know how to call functions in the
4680 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
4681 to i960_xxx in lower case.
4682 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
4683 not being defined yet.
4685 * remote.c (remote_open): Call start_remote to initialize
4686 wait_for_inferior during open.
4687 (remote_xfer_inferior_memory): Return length written rather
4690 * remote-vx.c (target_command -> vx_open): Use new generic
4692 * remote-eb.c, inftarg.c, exec.c: ditto.
4694 * infrun.c: Fix comments.
4695 (attach_program -> child_open): Use new generic target command.
4696 (wait_for_inferior): Clear saved register values before target_wait,
4697 so target_wait can set some of them if convenient.
4699 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
4700 Return success indicator, not void.
4701 (child_xfer_memory): Avoid fetching initial word if we'll
4702 overwrite it anyway.
4704 * infcmd.c (attach_command): Use new generic target open routine.
4705 (_initialize_infcmd): Update doc on attach and detach commands.
4706 (do_registers_info): Merge in a byte-order problem as a FIXME
4709 * findvar.c (find_saved_register): Avoid problem in current frame.
4710 (read_relative_register): Ditto.
4711 (write_register): Convert byte order on the way out.
4713 * exec.c (file_command): Add.
4714 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
4715 (xfer_memory): Common function between core_xfer_memory and
4717 (exec_xfer_memory): Use it.
4719 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
4721 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
4722 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
4723 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
4725 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
4727 Merge Intel 960 port of gdb, continuing...
4729 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
4730 symbol_file_command): Pass from_tty arg to hush 'em up.
4732 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
4733 Add magic numbers for 960 COFF format.
4735 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
4737 Merge Intel 960 port of gdb, from Intel "1.2" release.
4739 CHANGE_LOG entries from their port, which was based on
4742 Thu Sep 6 11:02:22 PDT 1990
4743 Remove temp file if download is interrupted.
4745 Wed Aug 1 09:08:33 PDT 1990
4746 Now uses binary protocol to talk to NINDY.
4747 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
4748 Times out after 5 seconds when trying to talk to NINDY.
4750 Tue May 29 12:54:49 PDT 1990
4751 Added variable baud rate (-b switch).
4752 Source code reorganization.
4754 Thu Apr 26 11:09:55 PDT 1990
4755 More cleanup of batch mode; specifically, execute "-s", "-e", and
4756 "-se" switches as soon as they are encountered on the invocation line.
4758 Fri Apr 20 13:47:15 PDT 1990
4761 Thu Apr 19 09:54:28 PDT 1990
4762 Add 'reset' command.
4764 Wed Apr 18 09:48:07 PDT 1990
4765 After opening remote tty, wait for 1 second to go by without input
4766 from it before trying to talk to NINDY (fixes problems with the
4767 Heurikon HK80/V960E).
4769 Mon Apr 4 16:33:05 PDT 1990
4770 Some output was not being suppressed in 'batch' mode.
4772 Thu Mar 22 15:31:11 PST 1990
4773 Ask user if old symbol table should be deleted when new file is
4776 Allow user to run a program downloaded before gdb960 was brought up.
4778 Correct "exec-file" help message for i80960 context.
4780 Correct bug in calculating user space address: could occasionally
4781 corrupt user program.
4783 Make sure to zero low-order bits in rip's because of bug in 960CA
4784 A-step part: could cause operation faults when "next"ing across
4787 Correct bug that made it impossible to get source line numbers for
4788 code loaded at addresses higher than 0x7fffffff.
4790 Wed Jan 10 12:43:22 PST 1990
4791 Open remote tty for exclusive use.
4793 Fri Jan 5 12:14:42 PST 1990
4794 Correct disassembly (CA manual was right after all):
4795 opcode for sysctl is 0x659
4797 Mon Oct 23 12:03:04 PDT 1989
4798 Use G960BASE and G960BIN environment variables to find 'sx' utility.
4800 Mon Oct 16 14:15:09 PDT 1989
4801 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
4803 Mon Oct 2 15:56:31 PDT 1989
4805 Added 960CA disassembly support.
4807 To simplify maintenance:
4808 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
4810 - eliminated opcode.h: incorporates tables into i960-pinsn.c
4811 - moved 960-specific routines from i960-pinsn.c to i960-md.c
4812 - made disassembly interface identical to that in gdmp960.
4816 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
4818 * target.h: Allow targets to stack. Add target_has_memory,
4819 _registers, etc. Restructure memory access and "info files"
4820 to walk the target stack.
4821 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
4822 target.c: Change tables to match target.h.
4823 * inflow.c (child_mourn_inferior): pop child_ops.
4824 (generic_mourn_inferior): Use new has_stack flag.
4825 * infptrace.c (child_xfer_memory): New memory regime.
4826 * inftarg.c (child_files_info): New "info files" regime.
4827 * remote-eb.c: New memory regime, new info files.
4828 * remote-vx.c: New memory regime, new info files. Now use
4829 separate targets for VxWorks attachment to machine, and
4830 actually running a process under VxWorks, since one has
4831 stack & execution & regs and the other doesn't.
4832 * remote.c: New memory regime, new info files.
4833 * sparc-xdep.c (fetch_core-registers): New memory regime.
4834 * target.c: New routines and support for stacked targets,
4835 new memory regime, new info files regime.
4838 Generalize section handling for an arbitrary number of sections,
4839 including use of the new BFD (binary file) library.
4840 * gdbcore.h: Add struct section_table.
4841 * exec.c (build_section_table): Iterate all sections and
4842 record what gdb needs to know about them.
4843 (exec_command): Use it.
4844 (exec_xfer_memory): Use the table.
4845 (exec_files_info): Print the table.
4846 * core.c (core_file_command, core_xfer_memory, core_files_info):
4848 * source.c (find_source_lines): Use bfd_get_mtime.
4849 * dbxread.c: Quick changes to make it compile with new BFD.
4850 * utils.c (error): Avoid using bfd_error in generic routines.
4852 * core.c (core_fetch_registers): Get from the ".regs" section of
4854 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
4856 * inferior.h (attach_flag): Export.
4857 * infcmd.c (run_command): use new target_create_inferior.
4858 * infrun.c (child_create_inferior): Don't return result.
4859 * Makefile.dist (VERSION): 3.91.4.
4861 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
4863 * breakpoint.c (bpstat_num): Handle breakpoints which have
4864 since been deleted, such as temporary breakpoints.
4865 infcmd.c (program_info): ditto.
4867 * core.c (core_file_command): Display the frame where the core
4872 * remote-vx.c (target_command): Merge in target command from
4873 targ-vx.c. A few other cleanups.
4875 * TODO, Projects: Lots more stuff to do...
4877 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
4879 Massive changes to wall off the remote-debugging interface
4880 behind a function vector. The port to handle VxWorks targets
4881 is also part of this.
4883 All files: Replace references to renamed functions,
4884 remove references to remote_debugging, remove references to
4885 have_include_file, have_core_file in favor of target_has_stack,
4886 target_has_memory, etc.
4888 * Modularize the breakpoint interface.
4889 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
4890 a breakpoint instruction.
4891 breakpoint.c: struct breakpoint's shadow_contents now sized as
4893 (insert_breakpoints): Vector to target to install breakpoints.
4894 (remove_breakpoints): Vector to target here too.
4895 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
4896 sparc-tdep.c (single_step): Use new breakpoint interface for
4897 the single-step breakpoints.
4898 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
4899 New file, contains routines to insert and remove breakpoints by
4900 reading out the old contents and later replacing them. This is
4901 how ptrace breakpoints work, and many remote systems as well.
4903 * tm-vxworks68.h: New config file, overrides a few things for
4904 Wind River's preferences.
4906 * target.h: New file, for transfer vector used to talk to the
4907 inferior (child, attached, core, exec, remote, etc). All accesses
4908 to the thing being debugged should come through these vectors.
4909 target.c: New file, routines to handle transfer vector.
4910 (various files): Add transfer vectors XXX_ops for the various
4911 targets and pseudo-targets (core files, etc) we support.
4913 * breakpoint.c (bpstat_stop_status): Further explorations of
4914 watchpoints and why things don't work all the time.
4915 (bpstat_alloc): New fn to allocate a bpstat and chain it.
4917 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
4918 the local gdbinit if it doesn't already have it.
4920 * core.c (core_ops): add and install.
4921 Allow core debugging without exec file.
4923 * dbxread.c (free_and_init_header_files): Merge two fns.
4924 (end_symtab): Free named symbol table when a new version comes in.
4925 (read_dbx_symtab): Relocate all kinds of symbols with base
4926 address. First step toward handling different text, data, bss
4928 (add_file_addr_command): Renamed add_file_command.
4929 (add_file_command): Vector to remote handler.
4930 Add "load" as an alias for "add-file" command.
4932 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
4933 non-returning functions.
4935 * exec.c: Add exec_ops, and push it as a target when an exec
4938 * infcmd.c (run_command): Pass executable file name and arg list
4939 separately when starting an inferior. Permit "run" when no exec
4940 file is specified, for VxWorks.
4941 (detach_command): Move to child_detach in inftarg.c.
4943 * inftarg.c: New file. Unix-child-specific routines, and the
4944 child_ops structure.
4946 * inferior.h (registers): Export "registers" as the way for
4947 target dependent register handlers to find gdb's local copy of
4948 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
4949 since it is now used by places that want wait_for_inferior to
4950 handle the grunge but want to see every trap from the inferior.
4952 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
4953 Eliminate remote_debugging hooks in terminal handling.
4955 * infrun.c: Replace start_inferior with child_create_inferior.
4956 Move all the hair of Unix shells and ptrace idiosyncracies into
4957 child_create_inferior, so remote handlers don't have to deal.
4958 Remove running_in_shell. Rename stop_after_attach to
4959 stop_soon_quietly, and use it in a few other places where we want
4960 to just call wait_for_inferior and get control back on the first
4961 trap. trap_expected now never takes a value > 1.
4962 (init_wait_for_inferior): Initialize static vars when a new
4965 main.c (gdbinit): Add new hook for .gdbinit file name, let
4966 it be overridden by config files as GDBINIT_FILENAME.
4967 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
4968 Both of these are used for VxWorks gdb.
4970 mcheck.c: rename include file "gmalloc.c" to avoid problems
4971 with system include file "malloc.c".
4973 param-no-tm.h: New include file, same as param.h but does not
4974 include the default "tm.h" file. This is used in files where
4975 the target is known, e.g. remote-eb.c or sparc-xdep.c.
4977 param.h: Now just a shell that includes tm.h and param-no-tm.h.
4979 remote-vx.c: New file, VxWorks remote debugging support. Uses
4980 RPC routines that are shared with the target system, in directory
4983 remote.c: Vectorize remote interface.
4985 source.c: Globalize source_path, and make an alias "l" for "list"
4986 since we now have the "load" command.
4988 sparc-xdep.c: Use new param-no-tm.h.
4990 symmisc.c (free_named_symtab): Add new function from Wind River.
4991 However, ifdef it out for now while we think about what it should
4994 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
4996 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
4997 non-Unix-children handle this with their own code in the target
5000 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
5001 source and target lists. Add vx-share to default list of include
5002 directories. Add new files to src and target lists: mem-break,
5003 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
5004 ${srcdir} versions of munch and createtags are used.
5006 * valops.c (find_function_addr): Split out of call_function.
5007 (call_function_by_hand): Rename call_function; this function
5008 calls functions in the target by laboriously patching the target
5009 word-by-word with the right stack, args, regs, etc.
5012 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
5014 Handle AMD 29000 a bit better.
5016 * remote-eb.c (readchar): Mask received char log to make it readable.
5017 (remote_start): Pass arguments down to executing program.
5018 Make startaddr unsigned.
5019 infrun.c (start_inferior): Accept args, pass them to
5021 infcmd.c (run_command): Pass args down to start_inferior.
5023 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
5024 the target object file format.
5025 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
5027 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
5028 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
5030 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
5032 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
5033 * TODO: We did a few things, we have more to do though.
5035 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
5036 * inflow.c (inferior_died): Clear deferred stores.
5038 * Debug problems with dummy frames and calls to the inferior.
5039 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
5040 * sparc-tdep.c (do_restore_insn): Simplify.
5041 (sparc_frame_find_saved_regs): Simplify and fix what we find.
5042 (sparc_push_dummy_frame): Simplify and fix what we push.
5043 (sparc_pop_frame): Slightly more hair here, deciding whether
5044 we are restoring a saved PC or returning to a return address in %i7.
5045 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
5047 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
5048 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
5049 * obstack.h (chunkfun): ditto.
5050 * defs.h (xmalloc, xrealloc): ditto
5052 * utils.c (quit): Grab the terminal from the child if necessary.
5054 * inflow.c (term_status_command): Rename to term_info, change
5057 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
5058 (is_delayed_branch): Speed up.
5059 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
5060 Still missing some float ops, and needs testing.
5062 * Support for input and output radixes other than base 10
5063 * defs.h (input_radix, output_radix): Declare.
5064 * expread.y (yyparse, parse_number): Handle changes of input
5065 radix, and ambiguous names-or-numbers in radixes >10.
5066 * printcmd.c (print_scalar_formatted): Print formatted hex
5067 numbers in varying column widths.
5068 * valprint.c (val_print): Use output_format to print scalar ints.
5069 (set_input_radix, set_output_radix, set_radix): Create.
5070 (set_output_radix): Set output_format from output_radix.
5071 (_initialize_valprint): add `set radix' but leave the others off.
5073 * main.c (execute_command): Let stupid questions be turned off.
5074 (_initialize_main): Handle "set stupidity", etc.
5076 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
5077 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
5079 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
5081 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
5082 bfd stuff is still screwed up, but with some manual work, it
5085 * breakpoint.c (bpstat_do_actions): Start over if a command
5086 proceeds the inferior, since the inferior will have stopped and
5087 will need to have its new stop-actions taken care of.
5089 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
5090 compiler fits, simplify it.
5092 * gdb.texinfo (directory command): Doc new dir command.
5093 source.c (directory_command): "dir" now puts things on the front
5094 of the path, moves dups up front, and handles multiple names
5095 on the command line, inserting each one in order. It also
5096 blows away cached line and full_filename info.
5098 * stack.c (backtrace_command): Skip "more stack frames follow"
5101 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
5102 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
5103 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
5104 The only odd one was Gould NP1, which had defined vprintf to
5107 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
5108 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
5109 variable, inspect_it.
5110 valprint.c (print_string, val_print): Use the global inspect_it
5111 to indicate whether to print in Epoch style or normal style.
5113 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
5115 * printcmd.c (call_command): add an alias for the "print" command
5116 which runs expressions and doesn't print the result if void.
5117 (print_command_1): implement it.
5119 * command.c: Remove #if 0'd code. Initialize all the fields
5120 in add_cmd (). Rename do_nothing_command to
5121 not_just_help_class_command, and make it externally visible.
5122 command.h: add user_commands to struct.
5123 * main.c (define_command): Don't overload c->function with a char
5124 string as well as a function pointer.
5126 * eval.c (evaluate_subexp): Reinstall tiemann changes to
5127 calling convention of value_struct_elt () that got dropped in
5130 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
5131 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
5133 * tm-sparc.h (POP_FRAME): replace some constants with defines.
5135 * sparc-xdep.c (store_inferior_registers): defer stores to regs
5136 until a good time (e.g. when we are about to run the child),
5137 saving ptrace calls.
5138 * infrun.c (proceed): handle DO_DEFERRED_STORES.
5139 * tm-sparc.h: define DO_DEFERRED_STORES.
5141 * sparc-xdep.c (store_inferior_registers): when storing float
5142 registers, don't store stack regs too. When storing the SP,
5143 however, DO store the stack regs too. This fixes a bug in which
5144 the dummy frame is not recognized when a call_function finishes,
5145 because its frame pointer (in the stack regs) was never
5147 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
5148 even though we don't know how to read them from an inferior.
5149 valops.c (call_function): Comment about storing SP.
5151 * infrun.c (save_inferior_status): Save away the original bpstat
5152 chain so it can be restored later. Install the copied version for
5153 use by whoever saved the status. It will be blow away by
5154 restore_inferior_status, and the original chain restored. This is
5155 important for people who have pointers into the original.
5157 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
5158 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
5159 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
5162 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
5164 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
5165 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
5166 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
5168 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
5170 * Merge Mike Tiemann's multiple inheritance changes from Sun.
5171 Store the baseclasses in a type struct starting from array element
5172 0 rather than from the unusual array element 1.
5174 dbxread.c: the above.
5175 (virtual_context): Add
5176 Read new debug information about which virtual function table
5177 a virtual function is from, and store it in fn_field.fcontext.
5179 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
5180 TYPE_FN_FIELD_STATIC_P.
5182 symtab.c: the above.
5183 valops.c: the above. Handle pointer casts of object *'s.
5184 (search_struct_method): Add.
5185 (value_struct_elt): First arg is now a pointer to a value, and is
5188 valprint.c: the above.
5189 values.c (value_virtual_fn_field): Add type arg. Handle
5190 offsetting to the proper object when calling virtual fns.
5192 (baseclass_addr): Add valuep arg.
5194 * README: Document the current state of BFD config (missing).
5195 * TODO, ChangeLog, Makefile.dist: Roll version.
5196 * WHATS.NEW: Add summary of changes since 3.5.
5198 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
5200 * dbxread.c (read_struct_type): Clear bit vectors whenever
5202 symtab.c (B_CLRALL): define.
5204 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
5205 using == rather than =. Huh... This fixes the dreaded problem
5206 wherein builtin_type_int becomes TYPE_CODE_FLT.
5208 * core.c (info_files): Show the inferior pid.
5210 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
5211 already knows how to look in the source directory.
5213 * Remove psymtab hair from many places. Remove duplicated code
5214 for searching symbol tables. Hide psymtabs from most places.
5215 Make it fast to get from a psymtab to its symtab.
5217 blockframe.c (blockvector_for_pc): Remove psymtab hair.
5218 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5219 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5220 dbxread.c: export psymtab_to_symtab, make it work if called N times.
5221 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
5222 new symtab completely. New psymtabs get symtab pointer
5223 initialized to zero. Remove MI warning printf.
5224 symtab.h: Comments. Add psymtab to symtab pointer.
5225 (PSYMTAB_TO_SYMTAB): New macro.
5226 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
5227 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
5229 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
5231 (print_frame_info): Avoid special-casing symbols that have not yet
5234 * source.c (open_source_file): Quick path if we have already
5235 located the source file by its full name.
5237 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
5238 find_pc_psymtab. When a name is found in the misc function
5239 vector, search the symbol table for its mangled name, not the
5240 name that the user typed.
5242 * bfd.h: Fix missing comment terminators, make #endifs match.
5244 * valarith.c (value_less): Handle unsigned int comparisons.
5245 Add FIXME about pointer compares, which assume host and target
5246 pointers are the same.
5248 * command.c (do_nothing_command): lint
5249 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
5250 fix comments on debug symbol format for visibility. Actually set
5251 visibility of symbols.
5252 main.c (echo_command): lint; use <readline/history.h>.
5253 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
5254 obstack.h (_obstack_blank): Rearrange pointer math to avoid
5255 pointing past end of allocated memory; saber complains.
5256 obstack.h: Declare the external functions that we use.
5257 valarith.h: use <string.h>
5258 solib.c (solib_add): lint.
5260 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
5262 * main.c (initialize_main): Default info_verbose to off, now that
5263 symbol reading is fast.
5264 (quit_command): Avoid clobbering exec_bfd while quitting.
5266 * Initial BFD (binary file diddling library) merger:
5267 coffread.c: Change AOUTHDR to struct exe_hdr.
5269 core.c: initialize initialized data at compile time.
5270 (core_file_command): Move from coredep.c, convert to bfd.
5271 (xfer_core_file): Convert to bfd.
5272 exec.c (exec_file_command): use bfd routines.
5274 mips-tdep.c: Remove exec_file_command and friends.
5277 * coredep.c: (fetch_core_registers) Convert core_file_command to
5278 fetch_core_registers.
5279 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
5281 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
5282 (my_bfd_read): More bogosity, which I don't think we call.
5283 (program_name): Remove this atrocity asap!
5285 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
5288 values.c: allocate_repeat_value was not clearing the
5289 optimized_out field.
5290 (value_static_field): minor stylistic fix (wrong macro was used).
5291 valops.c (value_struct_elt_for_address): didn't work for C++
5294 * signame.c (_initialize_signame): Initialize signal names once.
5296 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
5297 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
5298 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
5300 * remote-eb.c: Support user-settable baud rates on the serial port.
5302 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
5304 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
5306 * tconfig/sun3os4: Remove warning about native assembler,
5307 since it also occurs in the xconfig file.
5309 * findvar.c (registers): Allocate some slop after `registers'
5310 to prevent stray accesses from trashing the next variable.
5312 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
5313 on the sun-3, by changing the #ifdef from `sun3' (which is not
5314 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
5315 vars, which happened to follow `registers' in the executable.
5317 * readline/history.c (history_search): Heed gcc-2's advice
5318 and parenthesize && inside ||).
5320 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
5321 tm-29k.c: Insert FSF copyright headers.
5323 * remote-eb.c: Better comments.
5325 * Makefile.dist: Update to 3.91.6.
5326 * TODO: note PREPARE_TO_STORE problem.
5328 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
5330 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
5332 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
5334 * infrun.c (wait_for_inferior, at end): Don't set up
5335 prev_* if the inferior no longer exists.
5337 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
5338 CANNOT_EXECUTE_STACK.
5339 valops.c (call_function): Use it.
5341 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
5343 * inferior.h (PC_IN_CALL_DUMMY): New macro.
5344 infrun.c (wait_for_inferior, 2 places): Use it.
5346 * values.c (value_being_returned): Only use
5347 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
5349 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
5350 right thing for remote-eb.c.
5352 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
5353 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
5355 * blockframe.c: Put get_frame_saved_regs inside #if !defined
5356 (FRAME_FIND_SAVED_REGS).
5358 * findvar.c ({fetch,store}_registers): Check for
5359 REMOTE_{FETCH_STORE}_REGISTER macro.
5361 * findvar.c (get_saved_register): Add argument lval and
5362 change meaning of argument addr.
5363 findvar.c: Change calls to get_saved_register to reflect
5364 new calling convention.
5365 valops.c (value_assign): Use get_saved_register instead of
5366 find_saved_register.
5368 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5370 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
5371 an (uninitialized) pointer to one. Use "&" when passing it
5374 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5376 * coffread.c (getfilename): Use DGUX x_offset and x_name if
5379 * coffread.c (symbol_file_command): Put semicolon after
5381 Put safe_to_init_tdesc_context in #if defined (TDESC).
5382 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
5383 coffread.c: #include <sys/stat.h>.
5384 (read_coff_symtab): Typo: in_source_files -> in_source_file.
5385 Add missing ')' in check for "lc%" and friends. Remove
5387 Declare read_one_sym() at top of file.
5388 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
5389 MC68WRMAGIC can have the same value without causing a duplicate
5392 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
5394 * Allow a Makefile to be built without building the
5395 tm and xm file links that screw up builds in subdirectories.
5396 This is done with `config.gdb none', then you can do things
5397 like `make gdb.tar.Z'.
5398 * tconfig/none: Config file for no target system
5399 * xconfig/none: Config file for no host system
5400 * config.gdb: If no TM or XM files are called out by the
5401 host or target file, don't make links for them.
5403 * cplus-dem.c: Add documentation.
5405 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
5406 simple error, so the user's gdb doesn't crash due to some object
5407 file problem (e.g. somebody is rebuilding the file out from under
5410 * printcmd.c (print_address_symbolic): demangle the symbol.
5412 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
5413 Motorola copyrights in it. Make "make gdb.tar.Z" work.
5414 (alldeps.mak): sort and uniq all results from this; duplicates
5415 hose gdb.tar.Z link building. Remove RCS files from
5416 tconfig and xconfig. Add config files for sun386. Add
5417 a few odd files to OTHERS and HFILES.
5419 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
5421 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
5422 Roll version number to 3.91.5. Make lint work in bindir.
5424 * README: Document cross-debugging and new file structure.
5426 * blockframe.c: Lint. Include "value.h" to declare read_register.
5427 (find_pc_partial_function): remove duplicate line.
5429 * command.h: Lint. Declare error_no_arg and dont_repeat.
5431 * tm-news.h: Remove inadvertently duplicated stuff.
5433 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
5434 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
5436 * config.gdb: Allow `config.gdb host target' form. Clean
5437 up previous change that printed bogus messages when you just said
5440 * core.c: #include "command.h" for lint.
5443 * main.c: Remove some casts of enums. Lint.
5450 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
5452 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
5453 read it from memory. This will allow us to save ptrace calls
5454 eventually. Changed caller single_step too.
5456 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
5457 that we aren't going to use, saving many ptrace calls, especially
5458 when watchpointing or single stepping. Use some #define's for
5460 (store_inferior_registers): Ditto.
5461 (core_file_command): Use some #define's for constants.
5463 * tm-sparc.h: Add #define's for some register numbers, so we
5464 can eliminate the use of random constants in sparc-xdep.c.
5466 * stack.c (frame_command, print_frame_info, up_command,
5467 down_command) Remove frame_changed, since it
5468 causes a bug and doesn't seem to do anything useful. In some
5469 places it was used as a flag, in others as a stack level (?).
5471 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
5472 default is to use the portable (vprintf) version rather than the
5474 * xm-news.h (MISSING_VPRINTF): Add.
5476 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
5478 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
5480 * Remove stuff that forces -Bstatic linking of gdb, and warnings
5481 about linking debugged programs -Bstatic in the sun?os4 config
5482 files in tconfig and xconfig subdirectories.
5484 * main.c (main): Remove unreached exit(0) now that we exit
5487 * Create TODO file for online bug list. There are too many
5488 "little" bugs to keep track of on paper.
5490 * Change Projects file to refer to bug-gdb@cygnus.com
5491 rather than kingdon@ai.
5493 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
5495 * Makefile.dist (VERSION): 3.91.4 now.
5497 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
5498 (condense_misc_bunches): Add sanity check that misc_count is
5499 the same as the number of symbols in the bunch.
5501 * coffread.c: rename init_misc_bunches. Pass an argument
5502 to condense_misc_bunches (a zero).
5504 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
5505 every time we are called; don't rely on our caller to do it.
5506 (add_file): Remove call to init_misc_bunches.
5508 * mipsread.c: Only warn, don't error, if unknown symbol types.
5509 This keeps an old gdb from falling on its face if it sees newly
5510 extended symbol info. Rename init_misc_bunches.
5512 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
5514 * Merge in changes from Per Bothner for DECstations and other
5515 MIPS stuff. The rest is Bothner speaking:
5517 The next message is a merger of Alessando Forin's mips port with
5518 mine. I've tried to use my good if biased judgment to get
5519 the best of both. It *does* need testing.
5521 Some of the changes are general, *not* mips-specific.
5524 Didn't believe in little-endian bit order.
5525 There are still inconsistencies about whether flags
5526 like BITS_BIG_ENDIAN are integer (#if ...) or
5527 boolean (#ifdef ...). I tried to paper over them.
5529 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
5530 Moved some misc_function code that was common to
5531 {dbx,coff,mips}read.c to symtab.c.
5532 In the process, I think I cleaned things up a bit.
5533 At the same time, moved obsavestring and obconcat to symtab.c.
5536 Removed obsolete condense_addl_misc_bunches (use
5537 condense_misc_bunches(1) instead).
5540 Needed to include <sys/dir>, at least on DECstations.
5542 valops.c, mips-tdep.c, tm-mips.h:
5543 Added PUSH_ARGUMENTS macro to support funny argument-pushing
5544 conventions (when STACK_ALIGN is insufficient).
5545 Needed on mips, where doubles need 8-byte alignment,
5546 but ints only need 4.
5549 Removed cruft that was not being used.
5550 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
5553 Print $ before register-names (I think that makes things a little
5555 Never print two instructions, even if one delays.
5556 Removed hex-disassemble set_cmd. (This is not mips-specific,
5557 so I think the argument is whether it is generally worthwhile or not.
5558 I'm inclined to think not, given how easy it is to
5559 convert between radixes in gdb.)
5562 This is basically Alessando's code.
5563 It doesn't use obstacks; I changed it to use obstacks
5564 in a few minor places where using malloc causes a
5565 memory leak. (Probably, more places could/should be changed.)
5566 I added record_misc_function where it was missing.
5567 In symbol_file_command and add_file_command, I tried
5568 to make the code consistent with more recent versions.
5569 Minor sylistic changes in parse_procedure.
5570 Make a .gdbinfo. psuedo-symbol point back to the real
5571 procedure symbol (using the isym field).
5574 This is basically from my port, but with a lot of details
5575 and a number of routines merged in from Alessando's version.
5576 I basically used my code "raw" backtrace (use heuristics
5577 from the actual code, rather than symbol table info) - though
5578 the idea is Alessandro's. I feel my code is a little cleaner
5579 here, particularly in being a little more flexible, such as being
5580 able to handle gcc-produced code (which it now can).
5581 It also doesn't do frame caching (which is not useful
5582 more recent gdb versions).
5583 I also used my code for push_/pop_dummy, more or less.
5584 I tried to incorporate AF's code for testing sigtramp
5585 while backtracing; I probably got it wrong.
5586 Added mips_print_register, which tries to scrunch as much
5587 information as possible on a screen...
5588 Removed the skip-prologue set_cmd. As with hex-disassemble (see
5589 under mips-pinsn.c), I don't see anything mips-specific here,
5590 and I don't see it being all that useful anyway.
5593 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
5594 Use more register names (rather than hard-cases numbers).
5596 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
5598 * Hack up 3.90.11 changes:
5600 * Makefile.dist (depend): parameterize $(GCC).
5601 Add solib.c and solib.o.
5602 (readline): Fix vpath for both absolute or relative SRCDIR.
5604 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
5605 Also, let the part I didn't understand at least compile so
5606 I can test the rest. FIXME.
5608 * dbxread.c: Fix thinko using strcmp.
5609 (init_psymbol_list): declare static.
5610 (partial_symbol_file_open): Comment cleanups better, avoid
5611 cleaning up the string table since the caller will do that.
5612 Move the stat for mod time into symbol_file_command, temporarily.
5613 (There should be a mod time for each symbol file, eventually,
5614 to control its rereading. FIXME.)
5616 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
5617 SunOS, which gives error for shared libs otherwise. (From
5618 Schaefer, probably FIXME needs work for portability.)
5620 * solib.c: Move #include "param.h" to work.
5621 Lowercase all the Uppercase Letters In the Messages.
5622 (find_solib): Clean up inferior_so_name for debug printouts.
5623 Allow no argument, to mean all shared libraries.
5625 * symmisc.c: include param.h to get CLEAR_SOLIB.
5627 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
5629 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
5630 to 3.90.11. ChangeLog entries below are from this.
5632 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5636 * Makefile.dist (HFILES): Add tm-sunos.h.
5638 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5642 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
5644 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
5646 * sparc-opcode.h Added single-operand version of rett.
5648 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5650 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
5651 Put parens around gcc_p in expansion.
5653 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5655 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
5657 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5659 * Changes for Sun shared libraries:
5660 blockframe.c (find_pc_partial_function): If a non-text symbol
5661 is found, set *address = pc - FUNCTION_START_OFFSET.
5662 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
5663 Disable breakpoints instead of giving an error.
5664 source.c (select_source_symtab): Initialize cs_pst.
5665 symmisc.c: Call CLEAR_SOLIB if defined.
5666 symtab.h: Make text{low,high} CORE_ADDR not int.
5667 (psymtab): New field addr.
5669 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
5670 (record_misc_function): Give correct type for N_DATA symbols.
5671 (condense_misc_bunches): do "misc_function_count = j" regardless
5673 Take code which is shared between symbol_file_command and
5674 add_file_command and put it into partial_symbol_file_{open,read}.
5675 Split add_file_command into add_file_command and add_file.
5676 Make psymtab_to_symtab read in the string table if the file
5678 Two new parameters to read_dbx_symtab and start_psymtab.
5679 tm-sunos.h: New file.
5681 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5683 * infcmd.c: Change cont_command to continue_command and "cont"
5686 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5688 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
5690 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
5692 * values.c (USE_STRUCT_CONVENTION): Check for structures of
5693 size 1,2,4,8 rather than size < 8.
5695 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
5696 as necessary, not just once.
5698 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
5700 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5702 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
5704 * tm-news.h: Add CALL_DUMMY_*.
5706 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
5708 * config.gdb: In list_host, list_target, use ${i}, not $i.
5710 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5712 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
5714 * sparc-opcode.h: Change all store floating-point state register
5715 instructions to have the right match & lose fields.
5717 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5719 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
5721 config.gdb: If srcdir != ., create readline directory and
5722 copy a makefile into it.
5724 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
5725 consistency with POSIX.
5727 * breakpoint.c (bpstat_stop_status): Disable watchpoint
5728 when we exit its exp_valid_block.
5730 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
5732 * Makefile.dist: Bump version to 3.91.3.
5734 * Clean up handling of breakpoint commands (somewhat).
5735 Prompted by Tiemann bug report "cont 10" doesn't work any more.
5737 inferior.h: Add breakpoint_proceeded to inferior status struct
5738 and globals; save it and restore it.
5739 (clear_breakpoint_commands): Cleanup, remove old #define.
5741 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
5742 (save_inferior_status, restore_inferior_status): handle it also.
5743 (proceed): Remove earlier code that set breakpoint_proceeded.
5744 It is now set only in clear_proceed_status.
5745 (clear_proceed_status): Cleanup, use bpstat_clear rather
5746 than clear_breakpoint_commands. No callers need the stop_bpstat
5747 between clear_proceed_status and proceed.
5749 infcmd.c: Add breakpoint_proceeded definition and comment.
5750 (cont_command, jump_command, signal_command): Move call to
5751 clear_proceed_status right next to call to proceed.
5753 breakpoint.c (bpstat_do_actions): Avoid clobbering our
5754 caller's argument while running down the chain of breakpoints.
5755 Use new variable "breakpoint_proceeded" to determine when
5756 a command that it executes moves the inferior past the
5758 (bpstat_clear): Handle NULL argument.
5759 (bpstat_clear_actions): Avoid useless call to
5760 breakpoint_auto_delete.
5761 (delete_breakpoint): Clean up bpstat's that are pointing to
5762 the deleted breakpoint from the stop_bpstat chain.
5763 (breakpoint_auto_delete): Simplify.
5765 * Clean up handling of EOF, error on stdin, etc. This was
5766 prompted by a network problem that caused gdb to go into an
5767 infinite loop filling up its malloc'd memory.
5769 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
5770 not clear_breakpoints_commands, which is now gone.
5771 (main): If command_loop returns (e.g. from EOF on stdin), do
5772 a quit_command (looping back to command_loop if quit_command
5773 doesn't really quit).
5774 (command_loop): check result from command_line_input and
5775 exit if it returns NULL, rather than passing the NULL to
5777 (gdb_readline): Free malloc'd result space before returning
5780 * utils.c (query): Handle C-d to mean "yes", just as if the
5781 input was not a terminal. Also avoid infinite loop if EOF
5782 occurs in mid-input-line before newline. This allows
5783 query to be used at EOF on stdin with reasonable results.
5785 * infrun.c (proceed): Set breakpoint_proceeded.
5787 * values.c (value_as_long): Avoid infinite recursion for enums.
5788 (_initialize_values): Fix typo in help msg (kingdon).
5790 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
5791 RL_LIB for linking. This allows -lreadline for linking
5792 and nothing for dependencies, once readline is a real library.
5794 * config.gdb: Jim Kingdon: give useful error message if the
5795 host or target type is not recognized.
5797 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
5798 it just defines it. Dumb, but deal with it.
5800 * Jim Kingdon suggests:
5801 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
5803 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
5805 * Makefile.dist (VERSION): Bump version # to 3.91.2.
5807 * Clean up Bothner's changes.
5809 * blockframe.c (clear_pc_function_cache): New function.
5810 * blockframe.c: remake cache_pc_function_* static.
5811 * dbxread.c (symbol_file_command): remove references to
5812 cache_pc_function_* variables.
5813 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
5814 * printcmd.c: Avoid kludging a global variable (addressprint)
5815 to avoid printing the address of a string twice. Instead,
5816 pass the format letter 's' down low enough that it can be seen
5817 to avoid this problem.
5818 (print_formatted): Pass format arg to value_print.
5819 (restore_addressprint): Remove function.
5820 (do_examine): Avoid hacking addressprint, cleanups and such.
5821 (print_frame_args): Add a comment to a Bothner change.
5822 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
5823 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
5824 to wipe out the values cached in blockframe.c.
5825 * symtab.c (find_method): Add comment saying how big you must
5826 allocate to be "big enough". Per being terse again.
5827 * valprint.c (val_print): Handle format letter "s" to print
5828 strings without addresses. Add comment to vtbl printing code
5829 which casts with wild abandon. Rearrange reference-printing
5831 @0xaddr: value (print w/addressprint)
5832 value (print w/~addressprint)
5833 @0xaddr (parameter lists w/addressprint)
5834 or nothing (parameter lists w/o addressprint)
5836 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
5838 * Merge more changes from Per Bothner:
5840 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
5841 annoying) that I tried to improve it. Here are my suggestions.
5843 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
5846 Do automatic de-reference when taking the address of a reference.
5848 Don't deref_ref when printing parameter lists.
5850 More attempts at treating refernences properly.
5852 In val_print, if deref_ref==0, don't print dangling " = ".
5854 Add COERCE_REF macro, which de-references an REF.
5856 * Merge changes from Per Bothner:
5858 * Fixed (Sony news)-specific configuration problems.
5859 * Fixed other problems with using vanilla pcc and libc (enum problems;
5860 assumption that vsprintf exists).
5861 * Some major speed-ups (finc_pc_partial_function now caches a match;
5862 parsing avoids duplicate symbol_lookup calls).
5863 * Changed handling of baseclasses (no longer use baseclasses field
5864 of struct type, use the first n_baseclasses fields instead).
5865 * Various minor changes/fixes, most C++-related.
5868 Cache the most previous match from find_pc_partial_function.
5869 (Save both low and high ends of matching function's pc range.)
5870 This speeds up the loop of infrun.c:wait_for_inferior quite
5871 a bit, and makes step/next commands much zippier.
5873 Added an enum->int cast (otherwise, some compilers barf).
5875 No longer set baseclass offset to 0, since multiple
5876 inheritance now mostly works.
5877 Added a number of casts, to shut up compiler warnings
5878 (after stabs where made enums, not ints).
5879 When discarding a symbol table (in symbol_file_command),
5880 must clear the cache introduced in blockframe.c.
5881 Don't convert $vtbl_ptr_type to vtbl any more.
5882 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
5883 Mask off sign bit emitted by g++ for virtual table offset.
5884 Set voffset to -1 (not 1) for static member functions.
5886 Changed parsing/lexing of names to avoid doing symbol lookup twice
5887 (once when lexing to determine symbol class, once for real).
5888 Now only call symbol_lookup once. Fields of 'this' win especially big.
5890 Subpress printing addr twice in the case of 'x/s addr'.
5892 lookup_basetype_type is no longer used.
5893 Add find_methods as recursive helper function to decode_line_1.
5894 This allows multiple inheritance to work.
5895 Also, once one or more matches has been found, do not look in
5896 base-classes. (Baseclass methods would be overridden, anyway.)
5898 Removed baseclasses array in struct type.
5899 Instead of using baseclasses[i], use fields[i-1].
5900 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
5901 Changed sign convention of voffset (previous was inconsistent).
5903 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
5905 Used to assume existence of vsprintf. Re-written to not need it
5906 if HAVE_VPRINTF is undefined.
5908 typecmp was too pessimistic. Made it less so.
5910 Don't print space after address.
5911 If vtable points to a misc symbol (with 0 offset), print it,
5912 since that indicates the actual class of the object.
5913 Changed ype_print_derivation_info to use new inheritance
5914 scheme (without baseclasses vector).
5916 In value_primitive_field, fixed some bugs left over from previous set of fixes.
5917 Also, changes needed because TYPE_BASECLASSES were removed.
5919 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
5921 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
5924 If there is no path set, and the symbols don't indicate what directory
5925 a file was compiled in, look in the current directory. But either
5926 a path or a known compilation directory will prevent this.
5929 Three independent bug fixes:
5930 * Remove the #if 0 block that breaks some stuff.
5931 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
5932 adapt gdb to either SunOS 4.0.* or 4.1.
5933 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
5936 Instantiate the class T when looking for methods in it. (Tiemann@sun)
5939 (type_print) Demangle the name being printed.
5940 (type_print_base) Handle botched demangling without coredump (tiemann).
5943 (check_stub_method): Document routine.
5944 (tiemann) fix bug for no-arg functions
5945 Avoid clobbering beyond end of malloc'd storage.
5946 Terminate the argument list properly.
5948 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
5950 * Changes merged by John Gilmore:
5953 In breakpoint_1, use new print_address_symbolic instead
5954 of find_pc_partial_function. (This forces use of assembler-level
5955 addresses, and avoids misleading non-mangled source-level names.)
5957 Generalize ansi argument such that -1 means skip arglist totally.
5958 Removed global variable print_ansi_qualifiers (which made
5959 code non-reentrant), in favor of extra explicit arguments
5960 to internal routines.
5962 Add new helper function print_address_symbolic.
5963 Use find_pc_misc_function instead of find_pc_partial_function
5964 (since we want assembler-level symbols here).
5966 Print unknown function as just "f (...)", not "f (...) (...)".
5967 Use new fputs_demangled explicitly.
5969 Fixed a typing violation (problem: value.h cannot be imported
5970 without renaming many variable in this file).
5971 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
5972 decode_line_1: Moved forward some never-reached code.
5973 Made decode_line_2 skip function prologues correctly.
5975 fputs_filtered should not demangle by default.
5976 Add new fputs_demangled to demangle on demand..
5978 Change value_struct_elt to use value_primitive_field (using recursive
5979 utility function search_struct_field). This allows foo.bar to work
5980 for multiple inheritance (so far only for data fields).
5981 Change check_field in the same way (recursive helper function
5982 to support multiple inheritance).
5983 (Note: there are more of these problems that I haven't fixed.
5984 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
5985 value_of_this: 'this' symbol name is now just "this", note "$this".
5987 Don't print static members.
5988 Avoid printing "members of <type>" if there are none.
5989 Simplified type_print_derivation_info by merging duplicate code.
5990 Remove useless blank lines in type_print_base (ptype command).
5992 Added declaration of new routine value_primitive_field.
5994 Added value_primitive_field which is generalized version of
5995 value_field that can handle multiple inheritance (non-zero offsets etc).
5996 Re-implemented value_field to call value_primitive_field.
5998 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
6000 * infcmd.c -- insert else to avoid 'delete env' coredump when you
6001 delete the whole environment. Karl Berry reported the bug.
6002 * source.c - fix openp to avoid //'s in filenames, which
6003 trigger an Emacs bug causing it to not be able to find files
6004 when running gdb in a window.
6005 * dbxread.c - zap the #if 0 that botches the add-file code.
6006 It seems to work a lot better without all the code commented out.
6008 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
6010 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
6013 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
6015 * Makefile - added a ${CFLAGS} to a couple of entries,
6016 added remote-sa.sparc.c
6017 * added remote.sa-sparc.c, a modification of remote.c
6018 which conducts a dialog directly with the SparcStation prom.
6019 * breakpoint.c, infrun.c, sparcdep.c added
6020 remote_insert_breakpoint(), and remote_remove_breakpoint()
6021 to breakpoint.c instead of directly writing breakpoint instructions.
6022 * sparcdep.c on remote_debugging,there is no need
6023 to remove signle step breakpoint instructions.
6024 * main.c added "-epoch" flag and "int epoch_interface" to main.c
6026 * printcmd.c - epoch interface sends lisp expressions to open up
6027 epoch windows on inspection.
6028 * valprint.c - added arrayprint, and addressprint and made adding
6029 format controls easier
6030 * wait.h added a couple of undef's because we were getting
6031 complaints about WSTOPSIG and WTERMSIG begin redefined.

6101 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
6102 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME

6127 step_resume_break_address != NULL, even if another_trap.
6128 If trap_expected and we enter sigtramp, then set up a
