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

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

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

735 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
737 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
738 entries are enclosed herein. Not all of these changes
739 have been merged into the master GDB sources -- check the
740 ChangeLog above here for the merge log.
742 Mon Jun 3 17:05:45 EDT 1991
744 m2-exp.y Created. Tested outside of GDB for a few days. Proper
745 operators were added, C specific operators and tokens
746 removed. yylex() revamped to some extent. Still things
747 missing from the grammar, such as sets.
748 Tested for two weeks in GDB v3.5.
750 Tue Jun 11 17:23:48 EDT 1991
752 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
753 so they are built-in. Sort of a hack.
755 Fri Jun 14 12:53:51 EDT 1991
757 m2-exp.y Added range checking for numeric constants. Any numeric
758 constant is assumed to be of builtin type INTEGER unless:
759 (1) it is octal or hexadecimal, in which case it is a
760 CARDINAL; (2) it is too big to fit into an INTEGER, in
761 which case it is a CARDINAL.
762 eval.c Added simple range checking for +, -, and * on integers.
763 Doesn't work very well for *, since 6 * 1,000,000,000 =
764 1,705,032,704, which fails the simple test of result >=
765 first_operand, no matter in what order the operands are.
767 Tue Jun 18 14:11:30 EDT 1991
769 Broke the parser into parts, one containing the C grammar and the other
770 containing code to be shared by all of the grammars.
772 The following files no longer exist:
777 The following files were added:
779 c-exp.y (The C grammar)
780 m2-exp.y (The Modula-2 grammar)
781 parser-code.c (Code that is shared by the above grammar)
785 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
786 now necessary to use the Bison compiler compiler, since it
787 will generate function/variable prefixes other than yy.
789 Tue Jun 18 16:47:49 EDT 1991
791 symtab.[ch] Added the external variable working_lang, than holds the
792 value of the current working language.
793 Added the ennumerated type language_mode, with the values
794 language_auto and language_manual, the former meaning that
795 GDB sets working_lang as needed, and the latter meaning
796 that the value of working_lang is totally under user
798 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
799 REAL, BOOLEAN and CHAR. Also added the type codes
800 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
801 utils.c Added set_language_command and show_language_command to
802 implement the GDB support commands "set language" and
804 expression.h A number of identifiers were added to the type exp_opcode
805 to facilitate Modula-2 builtin functions, integer
806 division, and array indexing.
808 Wed Jun 19 13:25:58 EDT 1991
810 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
811 if the language specified by working_lang requires the use
812 of strict typing of expressions. Eventually, even this
813 will be able to be changed by the user.
814 Added the macro RANGE_CHECK, which evaluates to non-zero
815 if the language specified by working_lang requires the
816 checking of a value against the domain of its type.
817 Eventually, even this will be able to be changed by the
819 language.[ch] Predicates involving types (simple_type, ordered_type,
820 same_type, integral_type, numeric_type, character_type,
821 boolean_type, float_type) are added. These predicates are
822 based on the current value of working_lang, and are handy
825 Wed Jun 19 15:39:34 EDT 1991
827 eval.c Added the function type_array_rank which computes the rank
829 valarith.c Added the funtion value_bool, which when given a integer
830 value.h value (ie. struct value *) as an argument, it returns a
831 boolean value (ie. struct value *) true if that integer
832 is non-zero, and a boolean value false otherwise.
833 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
834 will print out properly.
836 Wed Jun 19 16:36:34 EDT 1991
838 valops.c Added the function value_capitalize, which returns it
839 value.h argument capitalized if its argument is a lowercase
840 letter, or the argument unchanged if its argument is not a
842 valarith.c Added the function range_check_p, which returns non-zero
843 value.h if its value argument is between the integral bounds upper
845 Added the function range_check_enum_p, which makes sure
846 that its value argument is a valid member of the domain of
848 Added the function range_check_range_p, which makes sure
849 its value argument lies between the upper and lower bounds
850 of its type argument, which must be a ranged type.
851 Added the function check_array_index, which range and type
852 checks an index of an array.
853 Added the function value_multi_subscript, which computes
854 array[idx1,idx2...idxN], given a value array and an array
855 of values representing indicies.
856 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
857 unpack_long to work with TYPE_CODE_BOOL and
860 Wed Jun 19 18:04:08 EDT 1991
862 symtab.c Stored pervasive types in a structure and make
863 lookup_pervasive_type() a lookup function that was based
864 on working_lang. If lookup_pervasive_type() returned
865 non-zero, then that value was returned (a fix, since
866 before it simply wouldn't return the pervasive type.)
867 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
868 non-zero if the language specified by working_lang means
869 "conversion" when it says "cast".
870 valops.c Added the function value_real_cast(), which performs a
871 value.h *cast*, not a *conversion*, which is what value_cast()
872 does when it can. In particular,
873 value_cast(<float_type>,4) = 4.0, while
874 value_real_cast(<float_type>,4) = some mess.
875 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
876 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
877 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
878 and MIN on integral types. *NOTE*: These are currently
879 hardcoded to work only if there are 8 bits per storage
881 eval.c Made logical functions call value_bool to return a
882 properly typed boolean value, based on working_lang.
884 Thu Jun 20 11:55:27 EDT 1991
886 valprint.c Types now print out in a Modula-2 fashion. This works for
887 the cases when the type is printed out step-by-step, that
888 is, it doesn't work when the name of a structured type
889 (which includes the keyword "struct", etc.) is simply
891 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
892 since type specifications in C and Modula-2 are very
893 different. The C printing of a type is very recursive,
894 whereas in Modula-2 it is generally very simple. C has
895 type prefixes and suffixes, which have no real analogue in
896 Modula-2. Maybe type_print() should call a language
897 specific type printer. This is also advantageous if we
898 compile GDB to exclude some of the languages. We'll just
899 leave those functions out.
901 Thu Jun 20 16:57:10 EDT 1991
903 dbxread.c When reading the complete symbol table in (via
904 psymtab_to_symtab()), the number and types of function
905 arguments are added to a function type. define_symbol()
906 calls add_param_to_type() to accomplish this.
907 Assumption: when we come across a function definition
908 (N_FUN symbol with an 'f' or 'F' in the name), its
909 arguments will appear before another function definition.
910 When a function is found, a pointer to its type is placed
911 in the global in_function_type. Changes that
912 add_param_to_type() makes are to this global.
913 valprint.c The type of a function now includes (for Modula-2) the
914 types of its parameters.
915 eval.c Type checking and a check for the proper number of
916 arguments is now done for function calls. Not sure of the
917 impact this has on C++ member function yet.
919 Thu Jun 20 19:58:48 EDT 1991
921 valprint.c Rewrote the type printer. Broke it into two language
922 specific parts, adding the functions type_print_m2() and
924 An unfortunate consequence is this: if you debugging a C
925 program in Modula-2 mode (why?), info types does not work
926 well with regular expressions, since the types are printed
927 out in Modula-2 terminology, but stored in C terminology.
928 language.[ch] Added the functions new_type_last(), type_keyword(), and
929 type_sep() to aid in the printing of typedefs.
930 symtab.c Made the printing of typedefs as language independent as
931 possible through calls to new_type_last(), type_keyword(),
934 Fri Jun 21 11:50:26 EDT 1991
936 dbxread.c Check all incoming ennumerated types. If it looks like
937 Modula-2's BOOLEAN type, then change the type_code of the
938 type to TYPE_CODE_BOOL so we can process it as a boolean
940 valprint.c Replaced some of the 0x%x with calls to sprintf and
941 hexformat() in val_print().
942 language.[ch] Added the function hex_to_string(), which converts its
943 integral argument to a hexadecimal number (format is
944 language based) and returns the result as a string.
946 Mon Jun 24 12:25:07 EDT 1991
948 valprint.c Some functions call type_print_1() directly, instead of
949 value.h using type_print(), so they can specify where (column) to
950 print things. Since type_print() takes care of language
951 dependence, that needs to be called first. Added a
952 parameter depth to type_print() (so it is now like
953 type_print_1). Changed type_print to type_print_at, and
954 made type_print a macro that passes a depth argument of
956 symmisc.c Changed all calls to type_print_1 to calls to
958 Makefile.dist Made it possible to build GDB for a specific set of
959 depend languages. Do this by passing a definition for the macro
960 LANGS to make. LANGS should be a string containing a
961 space-separated list of language names (ie. LANGS="c m2").
962 The default is to build all languages. Note that grammar
963 files must follow the naming convention of <lang>-exp.y.
964 gdb.lang This holds the current value of the LANGS macro. It is
965 examined every time make is called, and is updated if
967 eval.c Added #ifdef _LANG_<lang> to these files.
968 expread.c Still need to add them to dbxread.c and coffread.c.
976 Mon Jun 24 16:33:11 EDT 1991
978 language.[ch] Added the functions hexformat_pre() and
979 hex_to_string_pre(), which take a prefix argument to
980 include in the format string. Thus, hexformat_pre("08") will
981 return "0x08x" (if the working language is language_c).
982 Made hexformat() and hex_to_string() calls to the above
983 with "" as the prefix argument.
985 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
986 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
987 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
988 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
989 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
990 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
991 valprint.c, vax-pinsn.c
993 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
994 calls to hexformat() and hex_to_string(). Format strings without
995 the leading "0x" were ignored.
997 depend Updated to take the above into account.
1000 Tue Jun 25 15:27:18 EDT 1991
1002 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
1003 and type_check_t to keep track of the current state of
1004 range and type checking.
1005 main.c Added the variables range_mode, range_check, type_mode,
1006 and type_check to record the current state of range and
1007 type checking. Added initialization code to main().
1008 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
1009 the above variables.
1012 Tue Jun 25 17:57:08 EDT 1991
1014 dbxread.c process_one_symbol() updates the variable (enum language)
1015 source_lang based on the extension of the filename
1016 contained in the N_SO sybmol that started this symtab.
1017 When end_symtab() is called, the value of source_lang is
1018 put into the language field.
1019 stack.c select_frame() sets working_lang (and possibly type_check
1020 and range_check) to the language field of the symtab
1021 associated with the frame that is selected if working_mode
1022 is language_auto. If working_mode is language_manual, a
1023 warning is printed and working_lang is not set.
1024 language.c Added the function set_type_range(), which sets the value of
1025 type_check and range_check (if their modes call for
1026 automatic setting) based on the current value of
1027 working_lang. A non-zero argument will cause the current
1028 settings to be output.
1031 Wed Jun 26 14:51:40 EDT 1991
1033 eval.c Added range checks on assignment.
1034 m2-exp.y Added the grammar for sets to the language. Currently,
1035 these do not do anything except print an error message.
1037 Wed Jun 26 17:01:04 EDT 1991
1039 m2-exp.y Added the ability for parse_number() to parse negative
1040 numbers. A global flag is set upon encountering a unary
1041 minus. This was done to make, for example, 1 parse as a
1042 CARDINAL, and not as an integer, per Wirth's examples in
1043 Programming in Modula-2 ed.4.
1044 valprint.c Added support for "set radix 2" by then setting
1045 output_format to 't'.
1046 eval.c Implemented range checking on subrange types. Added calls
1047 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
1048 Implemented MIN and MAX for ennumerated types. The
1049 minimum value of an ennumerated type is defined by Wirth
1050 as the first identifier, and the maximum as the last.
1051 m2-exp.y Made octal numbers ending with "B" be characters and those
1052 ending with "C" be numbers, per Wirth's book. (p. 34)
1054 Thu Jun 27 14:11:52 EDT 1991
1056 stack.c select_frame() now only sets working_lang, it does not
1057 notify the user. If working_mode is language_manual, then
1058 a warning is issued once.
1059 main.c At the end of each call to execute_command(), working_lang
1060 is checked against the local static (enum language)
1061 current. If they differ and working_mode is
1062 language_auto, the new settings of language, type and
1063 range checking are printed out.
1064 stack.c Modified frame_info() to include the language of the
1065 current frame in the output of "info frame".
1066 language.[ch] Added the function language_str() which returns the name
1067 of the current language.
1069 Fri Jun 28 15:33:14 EDT 1991
1071 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
1072 the language. INCL and DECL currently cause an error,
1073 since sets are not implemented yet. INC and DEC are
1074 implemented as PREINCREMENT/PREDECREMENT with one
1075 argument, and as ASSIGN_MODIFY with two arguments.
1076 eval.c Added type checking to the above cases.
1077 value.h Added not_lval_constant to the lval_type ennumerated type.
1078 not_lval_constant means that the value is a constant
1079 value; that is 3 or 'a' or TRUE, not as in a constant
1080 identifier. This is used to help coerce numbers such as 3
1081 to either signed or unsigned numbers.
1082 valops.c Added the function value_coerce_constants() which coerces
1083 constant integers as following: if one is a constant and
1084 the other is not, the constant's type is set to the type
1085 of the other argument. If both are constants and one is
1086 signed, the other is converted to a signed constant.
1088 Sat Jun 29 17:26:29 EDT 1991
1090 valarith.c Added a better range checker. It now checks range
1091 (successfully) on integral operations [+-] (signed and
1092 unsigned) for any C sized type. Still does not work well
1093 for multiplication.)
1094 int_in_size() returns an integer that is coerced to fit into
1095 specified number of bytes.
1097 Mon Jul 1 13:04:14 EDT 1991
1099 language.[ch] Added the function binop_result_type(), which returns the
1100 builtin (struct type *) type that would be the result of a
1101 binop on the two values V1 and V2.
1103 Wed Jul 3 19:22:53 EDT 1991
1105 source.c Extended source_info() to include the source language in
1106 the output from "info source".
1108 Fri Jul 5 13:48:52 EDT 1991
1110 utils.c Moved the support functions for the GDB set/show commands
1111 dealing with language into language.c.
1112 language.c Added the function language_info(), which displays info
1113 about the current working language, type and range check
1114 settings. Called via the GDB command "info language".
1115 Added an initialization routine _initialize_language(),
1116 that sets defaults for the language, type and range
1117 variables and sets up the new GDB commands.
1118 main.c Language setup moved to language.c.
1121 Mon Jul 8 10:10:22 EDT 1991
1123 valarith.c Debugged the range checker for arithmetic. Still does not
1124 work for multiplication very well.
1126 Mon Jul 8 12:40:37 EDT 1991
1128 language.[ch] Added the function value_true() which returns non-zero if
1129 its argument represents a boolean true value.
1130 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
1131 check the truth of an expression.
1133 Thu Jul 11 12:51:34 EDT 1991
1135 language.[ch] Added the predicate structured_type(), which returns
1136 non-zero if the argument is a structured type.
1137 Added the predicate pointer_type(), which returns non-zero
1138 if the argument is a pointer type.
1139 eval.c Added the ability to do addition and substraction on
1140 pointers and integers. This case simply bypasses the
1143 Thu Jul 11 14:41:42 EDT 1991
1146 Added the symbol N_DEFD (0x4a) which is a definition
1147 module dependency that is used by the GNU Modula-2
1148 compiler and the linker. It is not important to GDB,
1149 except that [dbx|coff|mips]read.c should ignore these
1152 Fri Jul 12 16:07:00 EDT 1991
1154 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
1155 0 in val_print(). Also added statements to the else part
1156 to coerce type (argument to val_print) to a pointer type
1157 if it is an "array of unspecified length".
1158 valops.c Added the function value_m2_string(), which returns a
1159 (value) value which is a constant string, whose type is
1160 (ARRAY [0..n] OF CHAR). The length field of the type
1161 structure is set to zero, so it will be interpreted as an
1162 "array of unspecified length".
1163 stack.c Moved the language/frame mismatch check to
1164 main.c:execute_command().
1165 main.c The working language is recorded each time
1166 execute_command() is executed. If working lang has
1167 changed during its execution, then the new
1168 language/type/range info is printed out for the user. If
1169 the working language does not match the language of the
1170 frame, a warning is issued.
1172 Sat Jul 13 16:16:39 EDT 1991
1174 eval.c Moved all the type-checking stuff for operators to
1175 language.[ch] language.c. This is so we can keep language-specific
1176 stuff (like for what type operators are defined) in
1178 language.[ch] Added the function binop_type_check(), which checks to see
1179 if its two (value) arguments are type-compatible with its
1180 opcode argument. The opcode should represent an operation
1181 involving an operator. Also added the macro function
1182 unop_type_check, which calls binop_type_check with a
1183 NULL second argument.
1184 expprint.c Added Modula-2 operators to the op_print_tab, so info
1185 expression.h break works correctly. Also added "op_string", which
1186 returns the string corresponding to the (enum exp_opcode)
1187 opcode that is its argument.
1190 Sat Jul 13 18:26:18 EDT 1991
1192 coffread.c Added code to record the type of function arguments with
1193 each paricular function. Code is very similar to that
1195 dbxread.c Moved add_param_to_type() to symtab.c
1196 symtab.[ch] Added function add_param_to_type() from dbxread.c
1198 *** NOTE: The above additions have not been tested.
1200 Mon Jul 15 12:50:47 EDT 1991
1202 langauge.[ch] Added the functions type_error and range_error, which work
1203 like error() except if the type/range mode is set to
1204 *_mode_warn, then they do not do a return_to_top_level(),
1205 but merely print a warning.
1206 Also changed [set|show]_[type|range]_command() to support
1207 the new "warn" feature.
1209 Thu Jul 18 17:50:54 EDT 1991
1211 mipsread.c Added code to record the type of function arguments with
1212 each particular function. Code is very similar to that
1215 *** NOTE: The above additions have not been tested.
1217 Fri Jul 19 11:19:10 EDT 1991
1219 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
1220 UMIN_OF_SIZE, which when given a size of a numeric type,
1221 return the maximum and minimum value it can hold. UMAX...
1222 and UMIN... return the result for unsigned types.
1223 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
1224 struct types. They call above macros.
1225 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
1226 avoid a name conlict with the above.
1227 c-exp.y Added range checking on numeric constants in
1228 parse_number() for completeness.
1229 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
1230 return 0 if working_lang is not language_c.
1232 Thu Aug 8 14:17:22 EDT 1991
1236 breakpoint.c Documentation strings of some commands changed to
1237 eliminate the references to the C language where
1240 Tue Aug 13 15:48:03 EDT 1991
1242 m2-exp.y Added qualified identifiers to the grammar. The semantics
1243 are slightly different from those of the GDB operator ::
1245 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
1246 type_exp, where type_exp is any valid type expression.
1248 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
1249 printcmd.c Modified ptype_command() so it actually parses the input
1250 (necessary for type expressions with scope qualifiers).
1251 Added the function ptype_eval() which expects an
1252 expression composed of one OP_TYPE element.
1253 *.[ch] Replaced all occurences of parse_c_expression with
1255 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
1257 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
1259 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
1261 Small fixes from Peter Schauer:
1263 * infrun.c (child_attach): Lint.
1264 * solib.c (find_solib): Handle shared libs version 2.
1266 Small fixes from David Wood:
1268 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
1272 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
1273 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
1275 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
1276 chars_per_line is at maximum (user typed `set width 0'). Fix
1277 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
1279 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
1281 * coredep.c: include ptrace.h where necessary.
1282 * mipsread.c(parse_lines): fix unsigned char problem that was
1283 messing up line numbers on SGI's and possibly other MIPS based
1285 * infrun.c (child_create_inferior): use better test to check
1286 return val from setpgrp().
1287 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
1288 for sgi/irix support.
1290 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
1292 * mipsread.c (parse_symbol): Put non-static procedures
1293 in the global block.
1295 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
1297 Patch together `text_start' and `text_end' for 29K port.
1299 * exec.c (exec_command): If NEED_TEXT_START_END, define the
1300 variables and set them based on the exec file.
1301 * am29k-tdep.c: declare text_start.
1302 * valops.c (call_function_by_hand): declare text_end.
1304 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
1305 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
1306 because machines that do this will also have to know to
1307 set NEED_TEXT_START_END. Besides, it was a redundant way to
1309 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
1310 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
1311 NEED_TEXT_START_END.
1313 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
1315 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
1317 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
1318 Pass MUNCH_DEFINE to munch whenever we run it.
1319 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
1320 format string; use 0x%x instead.
1321 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
1322 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
1323 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
1324 * inflow.c: Handle `short' process group IDs.
1325 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
1326 and check for ptrace errors.
1327 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
1328 (coff_symfile_init): Initialize text_bfd_scnum.
1329 (read_coff_symtab): Use it to find the text [and absolute?] sections.
1330 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
1331 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
1332 Merge target arm case with other "easy" cases. Add target
1333 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
1334 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
1336 * minimon.h, remote-adapt.c, remote-mm.c: Add.
1337 * munch: Cope with RT/PC putting fns in data segment.
1338 Restore ability to override `nm' by specifying MUNCH_NM.
1339 * xconfig/rtbsd, xconfig/ultra3: New host systems.
1340 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
1341 and remote-adapt. Remove encapsulated coff #define's (the
1342 support should go in BFD, and gdb shouldn't know or care).
1343 * tconfig/a29k-kern: Same, but for remote kernel debugging.
1344 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
1345 * tm-29k.h: Update BADMAG (though it should go away).
1346 Allow the register definitions to be overridden in another
1347 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
1348 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
1349 DUMMY_SAVE_GR96, for handling kernel calling conventions
1350 that use GR64+ rather than GR96+.
1351 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
1352 remote debugging of Ultra3 kernel. Includes tm-29k.h and
1353 overrides various things.
1355 * remote-mm.c (mm_attach, mm_wait): Handle attach like
1356 child_attach does, making a clean stop in the newly attached
1358 * remote-eb.c: Lint.
1360 * coffread.c: Make coffread independent of any particular
1361 variant of COFF. Avoid #include-ing any particular one except
1362 internalcoff.h. BFD now passes key values for symbol reading
1363 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
1364 and the symbol masks and shifts); use them.
1365 Remove obsolete end_of_text_addr.
1367 * exec.c: Remove unused include files.
1369 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1371 * Makefile.in (documentation targets): Pass $(M4).
1372 Bugfix from eggert@twinsun.com (Paul Eggert).
1374 * stack.c (down_silently_command): Check for stack existence.
1376 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1378 * Makefile.in (VERSION): Update to 4.0.3.
1380 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1382 * core.c (core_file_command): Print frame at coredump with
1383 its level number, by calling print_stack_frame.
1384 * frame.h: Add selected_frame_level, print_stack_frame.
1385 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
1386 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
1387 Change print_sel_frame and print_selected_frame callers to
1390 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
1391 * symfile.c (free_named_symtabs): Ditto.
1392 * main.c (main): wrap_here needs an arg.
1393 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
1394 (solib_add): Avoid noise.
1395 (solib_create_inferior_hook): Lint.
1396 (sharedlibrary_command): Move dont_repeat to here.
1397 * utils.c (error): Call wrap_here to force buffered output.
1399 Small patches from Peter Schauer:
1401 * coffread.c (start_symtab): Free any existing line_vector before
1403 (read_coff_symtab): Ditto for type_vector.
1405 * source.c (lines_to_list): New variable, replacing function.
1406 (all uses): Use as variable.
1407 (_initialize_source): Add 'set listsize' and 'show listsize'.
1408 * utils.c (lines_to_list): Remove function.
1409 * stack.c (print_frame_info): Use as variable.
1410 * defs.h (lines_to_list): Remove declaration.
1412 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1414 * breakpoint.c (insert_breakpoints): Restore warning about
1415 the program might be running in another process, but only for
1416 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
1417 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
1419 * utils.c (error): if error_pre_print is set, print the string
1421 * main.c (main, print_gnu_advertisement, print_gdb_version):
1422 Reformat legalese so it always prints, but acts as an "I'm here"
1423 message while symbols are being read. If any errors occur,
1424 print a few newlines to set off the message and start it at the
1425 left margin. Remove mention of "help" command, and don't yak
1426 about symbol reading.
1427 (catch_errors): Error string is now printed first in case of
1429 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
1430 suggest the "help" command.
1432 * Makefile.in (VERSION): Set to 4.0.2.
1434 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
1436 * .gdbinit: Remove useless "rr" command. Set complaints
1437 to 1 for people debugging gdb.
1439 * breakpoint.c, remote-vx.c: Reword strings printed by
1440 catch_errors callers.
1442 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
1444 * WHATS.NEW: "history write -> history save". Doc "write on/off".
1445 (Fix from kenc@viewlogic.com.)
1447 Fix some infrastructure to be able to cope with host and target
1448 machines with different sized basic types (ints, ptrs, etc).
1449 (Idea from pierre@la.tce.com (Pierre Willard).)
1451 * values.c (value_from_longest): Rename from value_from_long.
1452 Handle pointer types as well as integers, so that targets with
1453 different pointer sizes from the host can be accomodated.
1454 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
1455 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
1456 uses of value_from_long to value_from_longest.
1457 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
1458 the correct pointer type to value_from_long{est}.
1460 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
1462 * remote-vx.c: Remove obsolete code for calling functions via
1463 vxworks kludge interface (it referenced value_from_long).
1465 * valops.c (value_string): Find malloc with lookup_misc_func, not
1468 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1470 Make writing to files work properly. (Fixes to BFD are also needed.)
1472 * core.c (core_open): Open file ourselves, read or r/w, depending on
1473 write_files. Use bfd_fdopenr.
1474 * gdbcore.h (write_files): New variable.
1475 * exec.c (write_files): Define variable, add set&show for it.
1476 (exec_file_command): Use write_files to open for read or r/write.
1478 Make shared library reading happen automatically. These changes
1479 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
1481 * inferior.h (stop_soon_quietly): Add to exported variables.
1482 * infrun.c (child_create_inferior): call solib hook, if defined.
1483 (child_attach): call solib hook, if defined.
1484 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
1485 (find_solib): Use lookup_misc_func rather than hand-rolled.
1486 (symbol_add_stub): New stub for catch_errors.
1487 (solib_add): Avoid output if !from_tty. Catch errors rather
1488 than just calling symbol_file_add and bombing.
1489 (solib_create_inferior_hook): Interface with the target process
1490 to let it read and alloc shared libs, then figure out what it did.
1492 * core.c (validate_files): Fix typo, soften warning.
1493 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
1495 * utils.c (fputs_demangled): Avoid duplicate printing if
1496 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
1498 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
1499 (Fix from pierre@la.tce.com (Pierre Willard).)
1501 * main.c (catch_errors): Change argument to a char * from an int,
1502 since a char * can point to a struct full of glop, but an int
1503 is not guaranteed to be able to hold a pointer.
1504 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
1505 breakpoint_re_set_one, breakpoint_re_set): Adapt.
1506 * core.c (core_open, solib_add_stub): Adapt.
1507 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
1509 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1511 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
1512 by adding .NOEXPORT target.
1514 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1518 * Makefile.in (VERSION): Roll to 4.0.
1519 (gdb.tar.Z): Make refcard.ps as well, for shipment.
1521 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1523 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
1526 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
1529 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
1531 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
1532 reflect above name change
1534 * WHATS.NEW: correct pointer to refcard.
1536 * doc/gdb.texinfo: update New Features, Installing
1538 * doc/gdbint.texinfo: add short description of configure +template
1540 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1542 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
1544 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
1546 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
1547 tar file, add dependencies for referenced doc files.
1549 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
1551 * coffread.c, symfile.c, stack.c: saberized.
1553 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1555 * doc/refcard.tex: permuted Essential Commands sec
1557 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
1559 set/show symbol-reloading
1560 default set complaints 0
1562 RET-repeat disabled after prompted long displays
1563 processID (attach) interpretation of 2nd GDB cmdline arg
1565 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
1567 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
1568 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
1569 breakpoint.c, main.c: lint.
1571 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1573 Install new configuration scheme for GDB and friends.
1575 * config.sub: Translate ordinary names to three-part names.
1576 * configure: Use three-part names internally.
1577 * configure.in: Translate three-part names to filenames.
1579 * README, WHATS.NEW: Update for gdb-4.0.
1580 * Makefile.in: Roll VERSION to 3.99.
1582 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
1584 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
1585 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
1586 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
1587 to single structures rather than arrays; when passing
1588 their address, use &. This avoids trouble with bdead compilers.
1589 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
1590 instead. This avoids portability headaches.
1591 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
1593 * source.c (open_source_file): Avoid ANSI const bdeath by
1594 skipping declaration and then casting result value.
1595 * tm-hp300bsd.h: Clarify comment.
1596 * utils.c (strstr): Result is const char *; ANSI bdeath.
1597 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
1598 since system include file defines it differently from "defs.h",
1599 though the two are equivalent for our purposes.
1600 * tconfig/hp300bsd: Add m68k-tdep.o.
1602 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1604 * tconfig/sun*4: Remove warnings about system assembler.
1606 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1608 * mcheck.c: Avoid warning about undeclared abort fn.
1609 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
1610 it causes recursive calls to error() when used in cleanups.
1611 To do so requires that we make it a function, so we do.
1612 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
1613 * utils.c (do_cleanups): Remove the current cleanup from the
1614 chain *before* calling it, in case error() is called from it.
1615 The result won't be pretty, but won't be an infinite loop either.
1617 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
1619 * dbxread.c (read_struct_type): Grok anon structs for C++.
1620 (vb_name, vptr_name): Null terminate these strings.
1622 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1624 Minor bug fixes from BSD Net2 gdb:
1626 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
1627 returns 0, there is no previous frame.
1628 * breakpoint.c (commands_command): If !from_tty, don't call
1629 input_from_terminal_p().
1630 * dbxread.c (record_misc_function): Speed up slightly.
1631 (compare_psymbols): Ditto.
1632 * infcmd.c (do_registers_info): Take a second argument to
1633 determine whether to print float registers. "info registers"
1634 does not do so anymore. "info all-registers" does, now.
1635 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
1637 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
1638 * inflow.c (initialize_inflow): Set tflags_ours correctly.
1642 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
1643 executing_breakpoint_commands if we are interrupted by error.
1644 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
1645 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
1646 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
1647 catch_errors() so we can setup the frame regardless of whether
1648 the shared libs work.
1649 * ieee-float.c (double_to_ieee_extended): Get exponent from
1650 right place in little-endian systems. From John Carey.
1652 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1654 * main.c: Remove unused terminating_signals and catch_termination().
1655 (long_options): Terminate with a zero element.
1656 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
1657 (gdb_readline): Make call-compatible with readline.
1658 (init_signals): Improve comments re vfork vs. signal.
1660 * utils.c (prompt_for_continue): Use new gdb_readline().
1661 If we prompt for continuation, we don't let CR repeat the previous
1662 command, once we get back to a prompt. It's too easy to keep
1663 hitting CR, expecting "--more--" prompts, and have some long
1664 command start repeating on you.
1666 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1668 * blockframe.c (frameless_look_for_prologue): Speed up by
1669 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
1670 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
1671 Define two variants, one faster.
1672 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
1673 and return zero, rather than giving an error.
1674 (setup_arbitrary_frame): Initialize the PC in the new frame.
1675 (skip_prologue): Add a second arg saying whether we're just
1676 checking for a frameless function or not.
1678 * core.c (core_open, core_close, core_xfer_memory): Move
1679 section table pointers and bfd* into the target_ops.
1680 (core_open): Allow errors in shared lib reading, etc.
1681 (core_files_info): Describe shared library sections.
1683 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
1684 exec_files_info, set_section_command): Move section table
1685 pointers and bfd* into the target_ops.
1686 (add_to_section_table): Add BFD to section table.
1688 * target.c (target_xfer_memory, target_info): Pass target to
1689 xfer_memory and target_info functions.
1692 * gdbcore.h: Move struct section_table.
1693 * target.h: New home of struct section_table.
1695 * solib.c (solib_add): New argument is the target_ops whose
1696 section list is to be added to, if any. Reallocate the
1697 sections in that target to add any that come from shared libs.
1698 (throughout) so_sections renamed to sections.
1699 (solib_xfer_memory): Deleted.
1700 * tm-sunos.h (SOLIB_ADD): Add target argument.
1701 (SOLIB_XFER_MEMORY): Delete.
1703 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1704 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
1705 from target_ops. It's the same on all targets. Add two section
1706 pointers to target_ops.
1708 * stack.c (find_relative_frame): Dump ancient algorithm for
1709 "down", just use handy "next" pointers.
1710 (frame_command): Don't error if there is no stack; let user
1713 * inflow.c (new_tty_prefork, new_tty): New prefork routine
1714 modifies static state in the parent process; new_tty itself
1715 runs in the child and modifies the child's file descriptors
1716 to match the saved static state.
1717 * infrun.c (child_create_inferior): Call new_tty_prefork,
1720 * infptrace.c (child_xfer_memory): Add ignored target arg.
1721 * remote-eb.c (eb_xfer_inferior_memory): ''
1722 * remote-nindy.c (nindy_xfer_inferior_memory): ''
1723 * remote-vx.c (vx_xfer_memory): ''
1724 * remote.c (remote_xfer_memory): ''. Rename from
1725 remote_xfer_inferior_memory.
1727 * main.c (main): Only try to attach "corefile" argument if
1728 it starts with a digit.
1730 * symfile.c (symbol_reloading): New "set/show" variable.
1731 (symbol_file_add): Shorten message about symbol reading.
1732 (add_symbol_file_command): Merge with add_syms_addr_command,
1733 since this should work on all targets now.
1734 (stop_whining): Default to zero, to shut up complaints
1735 about bad symbol tables on many systems.
1736 (free_named_symtabs): Just exit unless symbol_reloading.
1738 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
1739 and add comment explaining shared library screw.
1741 * source.c: #if defined => #ifdef.
1743 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1745 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
1747 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1749 * doc/rdl-apps.texinfo: provide default readline-appendix finder
1750 (doc/Makefile knows how to make one for local config)
1752 * Makefile.in: use doc/Makefile for doc targets
1754 * doc/Makefile: GDB documentation now has its own Makefile
1755 doc/refcard.tex: renamed from "gdbrc.tex"
1756 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
1757 doc/gdbint.texinfo: add markup in "Cleanups" chapter
1760 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1762 * values.c (baseclass_addr): When reading target memory, use the
1763 length of the basetype, not the upper type. We've only malloc'd
1764 enough space for the basetype, leading to errors in free().
1766 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
1767 ends up as a function specially, since we know the actual type of
1768 the pointed-to address. This (somewhat) fixes display of
1769 expressions that include misc_function_vector names. Try `cond 1
1770 !strcmp("a","b")' then `i b'.
1772 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
1773 The child can be proceeded from inside wait_for_inferior in
1774 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
1775 getting skipped in that case.
1777 * expprint.c (print_subexp): Use filtered output, since the
1778 subroutines we call use it, otherwise the output is horribly
1779 mangled, since output of wrappable stuff comes out late.
1781 * Makefile.in: Bump VERSION to 3.98.1
1783 * infrun.c (child_create_process): Use execlp to find the
1784 shell to exec our target program. This requires some fiddling
1785 with `environ' since there is no execlpe().
1787 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1789 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
1790 Minor rearrangement of refcard permits two new make targets--
1791 gdbrc.dvi DVI output for refcard, using CM fonts
1792 gdbrc.ps PostScript refcard, using PS fonts
1794 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1798 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
1799 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
1801 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1803 * doc/gdb.texinfo: last changes for release.
1804 Minor typo and formatting fixes; incorporated most fixes remaining from
1805 filed mail commenting on earlier drafts.
1807 Added warnings: pipes don't work in run command;
1808 conditions are converse of assertions;
1809 step over fn without debug info goes to next fn;
1810 vars may have "wrong" values near fn entrance, exit
1812 Added example from Kingston on printing repeated nonadjacent values
1814 Added explicit mention that in Emacs gdb mode C-c and C-z are like
1815 shell mode for signals
1817 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
1818 doesn't sound so much like its parent "Stopping and Continuing"; also
1819 moved entries on continue to top of section, so they don't get lost.
1821 Improved installation directions in appendix, added manual formatting
1824 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1826 * configure.in: Remove xm.h and tm.h even if we aren't linking
1827 new ones, so "./configure sun4; ./configure none" does the right
1828 thing. Assume that alldeps.mak and depend are already built in
1829 srcdir, and avoid running "make" (particularly "make depend",
1830 which involves "gcc") from inside configure. Build Makefile
1831 directly rather than building Makefile.conf first.
1832 * configure: Regenerate with above changes.
1833 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
1834 to 3.98. Revise gdb.tar.Z procedure to produce a file
1835 called gdb-$(VERSION).tar.Z but which unpacks into a
1836 directory called "gdb". Move non-source files out of
1837 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
1838 (depend): Don't try to do "gcc expread.y".
1839 (expread.o): Update dependencies by hand.
1841 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1844 Fixed a variety of small typos that prevented info from formatting
1845 cleanly; altered too-long heading for GPL Appendix, as discussed
1846 w/RMS; Changed date on cover to July 91.
1848 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1851 (1) Applied some fixes due to comments from Larry Breed (easier ones
1852 through chapsec 5.2)
1853 (2) Eliminated use of @footnote---had my doubts about it anyways, and
1854 it's broken in latest texinfo
1855 (3) Introduced *some* use of [] for optional arguments, where
1856 explanation is not simpler by listing cmd w arg and cmd w/out arg
1857 separately. Still not using @deffn.
1858 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
1859 couple of headings are too long. Need patches to texinfo or revision
1862 * Partial update to README (which still needs work for this
1863 release!): (1) use of configure corrected for new script,
1864 (2) "make gdb.dvi" and "make gdb.info" mentioned.
1866 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
1868 * symtab.c (lookup_symbol): Don't complain right off about
1869 no debug symbols; use the misc function vector first.
1870 (list_symbols): Use misc function vector to find symbols
1871 that don't have debug info, and print them.
1872 (find_pc_symtab): Temporarily avoid fatal() when psymtab
1873 PC range doesn't match symtab PC range, as it does on the
1874 MIPS because our symtab reading isn't perfect.
1876 * dbxread.c (dbx_symfile_read): Make warning about
1877 "no debug symbols" slightly nicer.
1879 * source.c (select_source_symtab): If "main" symbol exists,
1880 but decode_line_spec can't find line info, don't just return
1881 a zero; try other source symtabs or give an error.
1883 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
1884 their low addresses first, then rip through fixing high addrs.
1886 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
1887 <runene@ifi.uio.no>.
1888 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
1890 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1892 * Minor, mostly mechanical, cleanup of doc subdir for clean
1893 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
1894 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
1896 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
1898 Mostly MIPS and general symbol-reading fixups.
1900 * doc/gdbint.texinfo: Add documentation on symbol-reading
1903 * mipsread.c: Remove kludges around #include "ecoff.h".
1904 Remove redefinitions of a_magic, etc, no longer used.
1905 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
1906 Fix global overview comments to match symfile.c protocol.
1907 (mipscoff_new_init): Eliminate cur_hdr if we have one.
1908 (mipscoff_symfile_read): Eliminate unused code. Avoid
1909 sorting all the symtabs, when all we have read here is psymtabs.
1910 The symtabs are sorted as they are created anyway. Tell
1911 condense_misc_bunches whether we're mainline.
1912 (psymtab_to_symtab_1): Pass filename when recursing, to make
1913 stack trace more informative.
1914 (parse_partial_symbols): Assume cur_hdr as argument.
1915 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
1916 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
1917 the TYPE_NAME of char *, since that's done in symfile.c.
1918 (free_numargs, parse_symbol, add_symbol, add_block,
1919 shrink_linetable): Declare these fns void.
1920 (upgrade_type): Convert tree of if's to switch. Clean up
1921 bogus "off == 0" handling with a complaint. Avoid setting
1922 field bitpos and bitsize of array with lower and upper bounds.
1923 Check specified bitsize of elements against their actual type's
1924 bitsize, and complain if different. Complain about unknown
1926 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
1927 (psymtab_to_symtab_1): Print names of subsidiary files that
1928 are being read in. FIXME, we read far too many files. This code
1929 is not the problem, the problem is in parse_fdr where the psymtabs
1931 (cross_ref): Result should indicate that we used one aux entry
1932 normally, or two if we encountered a "next" entry. This used
1933 to leave the caller pointing at the wrong aux entry.
1934 (add_symbol): If overflowed cur_block, reallocate it larger,
1935 chase all pointers to it, and complain(), rather than clobber memory.
1936 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
1937 (new_field): Only allocate one field initially, not two.
1938 Pull ++ out of macro argument. Simplify.
1939 (_initialize_mipsread): Avoid initialization of importd
1940 global_psymbols and static_psymbols.
1942 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
1943 to properly set pst->symtab; avoid searching for it.
1944 (symfile_fns): Improve comments, add a FIXME.
1945 * dbxread.c: Update comments to reflect symfile protocol.
1946 (read_ofile_symtab, end_symtab): Return the symtab.
1947 (psymtab_to_symtab_1): Set pst->symtab.
1949 * coffread.c (coff_symfile_read): tell condense_misc_bunches
1950 whether we're mainline.
1952 * symfile.h (sym_fns): Remove unused sym_discard member.
1953 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
1955 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
1956 the environment variable is not.
1957 * infcmd.c (finish_command): Use filtered printfs.
1958 * cplus-dem.c: Add struct tags to a few unnamed structs.
1959 * valops.c (value_coerce_array): Improve comments.
1960 * valprint.c (type_print_varspec_suffix): Print array size only
1961 if greater than zero.
1962 * m88k-tdep.c: Shift some lines left by one space, that had
1963 apparently been trashed at some point.
1964 * TODO: More things to do, a few got done.
1966 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1968 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
1969 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
1971 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
1972 * expread.y, findvar.c, symmisc.c: Ditto.
1973 * printcmd.c (address_info): Update printed forms of LOC_
1974 symbols. Elim LOC_EXTERNAL.
1975 (print_frame_args): Keep track of param stack offsets before
1976 re-looking up to find the local register param is kept in.
1978 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
1979 Further integration of mipsread into gdb. Eliminate unused
1980 routines, duplicate declarations. Handle static symbols in
1981 psymtabs as well as external symbols. When reading symtabs,
1982 insert symbols into the correct block (global, static, or a local
1984 (read_mips_symtab, parse_partial_symbols): Don't pass useless
1986 (mipscoff_symfile_read): Don't call select_source_symtab.
1987 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
1988 rather than SYMBOL_VALUE.
1989 (parse_external): Comment clobbering of top_stack.
1990 (parse_partial_symbols): Update comments. Allocate and parse
1991 static symbols as well as external symbols. FIXME, enum values
1992 are not handled in this pass, but should be. Inline new_psymbol.
1993 Use SYMBOL_VALUE_ADDRESS.
1994 (psymtab_to_symtab_1): Read symbols into global static block
1995 by default (until enter some function's local block context).
1996 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
1997 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
1999 * source.c (select_source_symtab): Select a source symtab
2000 from either the symtabs or, failing that, the psymtabs.
2001 (list_command): Update error message.
2002 (forward_search_command, reverse_search_command): Use getc, not
2003 fgetc, for speed. FIXME, add comment about buffers that die if
2004 overrun by long line.
2006 * values.c (unpack_field_as_long, modify_field): Avoid shifting
2007 by an entire word, which is not portable, if we have a 32-bit
2008 field. (Code in dbxread.c already turns such bitfields, if
2009 aligned, into ordinary ints, but fixing this will help for other
2010 symbol formats and for future changes.)
2011 * core.c (core_open): Handle ANSI const brain death.
2012 * utils.c (vprintf): Fix varargs typo.
2014 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
2016 * findvar.c (find_var_value): Handle &function better.
2017 * TODO: Document work needed on &fn and &array.
2018 * printcmd.c (print_address_symbolic): New arg is the prefix
2019 to print if a name is printed.
2020 (print_address_demangle): Honor "set print address" now.
2021 Use new arg above to improve spacing of output.
2022 * valprint.c (val_print): When printing function pointers,
2023 print symbolic form too.
2024 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
2026 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2028 * core.c (memory_error): Reword error msg to mislead less.
2030 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
2032 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
2033 parse_partial_symbols): Use newer BFD internals (external_filehdr
2034 and external_aouthdr), byte-swap the fields that we care about
2035 before using them, and make the file header data local to
2036 read_the_mips_symtab rather than global.
2038 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
2040 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
2041 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
2043 * main.c (command_line_input): Flush stdout and stderr
2044 before every call to readline. This reportedly fixes a bug
2045 that comes up in Sys V running emacs-gdb and/or xxgdb,
2046 when stdin/out are pipes or sockets.
2048 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2050 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
2051 Avoid declaring Makefile dependencies, because GNU Make stupidly
2052 tries to update it if we do.
2054 * coffread.c: Revise for minor changes to bfd internal coff
2057 * configure: If -template= is given a relative path, make it
2058 absolute before recurring in subdirectories.
2060 * configure, configure.in, Makefile.in: Install "configure" script
2061 as replacement for config.gdb.
2062 * config.gdb, Makefile.dist, Makefile.sdir: Remove
2063 * README: Update for configure, mostly. FIXME.
2065 * Add dec3100 as equivalent to littlemips. Indicate in all host &
2066 target config files that they are for the host. When the lines
2067 get copied into the Makefile, this makes it more obvious what's
2070 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2072 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
2073 tabs, which end up in the disassembler output inadvertently.
2075 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
2077 Make it compile cleanly in an ANSI GCC2 environment.
2079 * blockframe.c: <stdio.h>
2080 * cplus-dem.c: free takes a void *, ifdef __STDC__
2081 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
2083 * defs.h (alloca): Avoid doing anything if alloca already def'd.
2084 * stddef.h, stdlib.h: Remove these files.
2085 * symtab.c: Avoid declaring qsort, close.
2086 * symfile.c: Avoid declaring close.
2087 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
2088 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
2090 Assorted other changes.
2091 * dbxread.c: include "libaout.h", not "liba.out.h".
2092 * printcmd.c (print_frame_args): Set recurse properly for
2093 indentation of struct and array parameters.
2094 * valops.c (value_cast): Allow cast to void.
2095 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
2096 single_step() in a target-independent fashion.
2097 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
2098 set up to be ready to continue. This makes us target independent.
2099 * infptrace.c (child_resume): Remove call to single_step; now
2100 can single step a SPARC target of any kind.
2102 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2104 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
2105 docn into separate sections---basically chapters, plus two loose
2106 pieces that can be configured to go in different places. This
2107 allows GNU m4 to preprocess the manual without coredumping.
2109 * Makefile.dist: tell TeX where to find texinfo.
2111 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2113 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
2114 the new target "rdl-apps.texinfo" which captures the Makefile
2115 variable that records where to find the Readline libraries.
2117 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
2119 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
2120 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
2121 * defs.h (const, volatile): Only define if not already defined.
2122 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
2124 * README: Update for release 3.95.
2125 * config.gdb: Don't create readline dir in subdir builds.
2126 * main.c: Include with "..." form for non-system include files,
2127 so "gcc -MM" for "make depend" works.
2128 Include readline files with "...h" rather than <readline/...h>.
2129 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
2131 * coffread.c: Undo minor damage done by Rich Pixley. Use
2132 different internal and external representations of COFF
2133 data structures. Use new BFD routines for swapping them in and
2135 * symfile.c (free_named_symtabs): Avoid freeing file names that
2136 are null or empty. Old i960 tools seem to produce files that
2137 claim to have empty names, causing each successive file read
2138 to blow away the previous one.
2139 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
2140 Move deferred_stores to top of file, but don't separate its
2141 #define's from its variable. Add commentary.
2142 * Makefile.dist: Fix Rich damage; undo "configure" changes in
2143 favor of keeping the (working) config.gdb. Move readline
2146 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
2148 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
2150 * infptrace.c (fetch_registers): no result, since now void.
2151 * tconfig/news: target depends on m68k-tdep too.
2153 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2155 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
2158 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
2159 applied various small fixes due to or inspired by RMS comments
2161 * doc/gdb.texinfo: finished using all RMS comments, save those for
2162 appendices on readline and cmd history (which are in other source
2165 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2167 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
2168 chapter 9; (2) documented 'break' command's menu mode for
2169 overloaded names, in response to hgs problem report C++ p-31
2171 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2173 * doc/gdb.texinfo: (1) better introductory example; (2) more
2174 consistent use of @code, @samp, @file, @kbd throughout; small
2175 cleanups to first three nodes; (3) new "Contributors" node;
2176 (4) Appendix, Renamed Commands; (5) divert specialized startup
2177 instructions to "Targets" chapter for generic manuals, while
2178 leaving them up front for manuals specific to specialized
2179 environments; (6) apply fixes from RMS comments through chapter 4.
2181 * pretex.m4: modify explanatory text slightly (and redefine
2182 "regexp") to keep GNU m4 from complaining. (It still crashes
2183 later, but one step at a time...)
2185 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
2187 * readline/readline.c (update_line): Avoid dereferencing a pointer
2188 before comparing it to its bounds. Saber caught this.
2189 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
2190 and only set PC if tgetstr returned non-null. Saber caught this.
2192 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2194 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
2195 stuff for config manual) here where it counts; updated
2196 to use new subdir structure (gdb/doc/).
2198 * Makefile: generated from above via
2202 * gdbint.texinfo: added instructions on generating gdb.info* files
2203 locally for release. These are ordinary info
2204 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
2205 Makefile)---but due to use of texinfo 2, can't count on makeinfo
2206 to generate these, so we distribute them already formatted.
2208 * gdb.texinfo: included full Info node and menu crud (as generated
2209 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
2211 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
2212 put in comments-for-future gdb.info target (one day makeinfo will
2215 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2217 * gdb.texinfo: Updated to include new or old undocumented
2218 commands, at least the following (perhaps some others I forgot to
2219 record): info f, info float, info path, info program, info s, info
2220 set, info source, info terminal, info types, info user, set/show
2222 Also covered all recent GDB command renames for v4.
2224 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2226 * mipsread.c: Rather than keeping count of how many symtabs
2227 and psymtabs we have, for sorting purposes, count them when
2228 we need to sort. This fixes bug in rereading of symbol tables.
2230 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2232 * infcmd.c: renamed "info path" to "show paths"

2246 * coffread.c, exec.c, infptrace.c, inftarg.c, remote.c, solib.c,
2247 symtab.h, target.c, target.h: Lint.
2248 * core.c: setup and select frame after reading shared libs,
2249 else reading shared libs will clobber them. Lint.
2250 * utils.c (error): Force out any buffered wrap text.
2252 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2254 * remote.c: Remove decls of memory_insert_breakpoint
2255 and memory_remove_breakpoint, no longer used. (Suggestion of
2258 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
2259 to make it easier to interface to "configure"'d libraries.
2261 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
2263 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
2264 aliases for set/show print.

2320 * coffread.c [TDESC]: Move setting of debug_info from
2321 coff_symfile_read to find_linenos and make it work with BFD.
2323 * cplus-dem.c [__STDC__]: Make x{m,re}alloc return void*.
2325 * signame.c: Cast const char* to char* when assigning to sys_siglist.
2327 * utils.c (strsave): Make arg const char* not char*.
2329 * infrun.c (wait_for_inferior) [SHIFT_INSN_REGS]: Use

2350 Mips bringup and general cleanup
2352 * cplus-dem.c: Move CPLUS_MARKER define to after defs.h.
2353 * infptrace.c (PT_WRITE_D, PT_READ_D): Use correct values.
2354 (This still doesn't seem to make MIPS bkpts work.)

2356 (symbol_file_command, add_file_command): Remove, obsol.
2357 * printcmd.c (ptype_command): Say "an enum" rather than "a enum".
2358 Wrap output appropriately.

2361 * valprint.c (type_print_varspec_suffix): Wrap "ptype" output of
2362 enums appropriately.
2364 Wed May 1 14:10:22 1991 Jim Kingdon (kingdon at cygint.cygnus.com)

2368 * cplus-dem.c: Include defs.h and param.h.
2369 Makefile.dist: Don't hack in the "param.h".
2370 param.h: Don't include defs.h.
2372 * expread.y: Use a union to deal with the fact that type_stack
2373 can have both ints and enum type_pieces in it.
2374 ({push,pop}_type_int): New functions.
2376 Tue Apr 30 13:18:58 1991 Jim Kingdon (kingdon at cygint.cygnus.com)

2388 symtab.c, cplus-dem.c, value.h, expread.y, valprint.c,
2389 copying.awk, solib.c, inflow.c, symmisc.c
2390 : Lint. Use read_memory not read_memory_integer on CORE_ADDR's.
2391 Use {value_as,unpack}_pointer (added to values.c)
2392 not {value_as,unpack}_long on CORE_ADDR's.
2393 Use longest_to_int (added to defs.h) instead of cast to int.
2394 Remove from_tty arg to mod_path.
2395 Put symfile_bfd in {coff,dbx}read.c not symfile.h.
2396 Use OP_NULL instead of 0 where dummy enum exp_opcode needed.

2898 * expprint.c (print_subexp): Avoid switch fallthru on
2899 BINOP_ASSIGN_MODIFY, so we can print += and such.
2900 * frame.h: Fix typo.
2901 * inflow.c (kill_command): After killing inferior, print our
2902 current frame in the core file, if we have one.
2903 (generic_mourn_inferior): When inferior dies, either select
2904 the current frame (in the new target, e.g. core file), or
2905 set both the current and selected frames to NULL.
2907 Changes from Peter Schauer.
2909 * infptrace.c: Avoid <sys/ptrace.h> on USG.
2911 * Make all file names fit in 14 characters (sigh and damn!):
2912 mv hp300hpux-xdep.c hp300ux-xdep.c
2913 mv symmetry-xdep.c symm-xdep.c
2914 mv symmetry-tdep.c symm-tdep.c
2915 mv convex-opcode.h convx-opcode.h

2920 mv remote-sa.m68k.shar rem-m68k.shar
2921 mv remote-multi.shar rem-multi.shar
2922 * Makefile.dist, README, config.gdb, convex-pinsn.c,
2923 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
2924 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
2927 * command.c (user_info_1, user_info): New command for listing
2928 the user-defined commands.
2930 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
2932 * dbxread.c (really_free_pendings): Clear file_symbols
2933 and global_symbols after freeing them; otherwise, running
2934 this function twice (if it appears twice on the cleanup
2935 chain), we try to free things twice.
2937 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
2938 based on text_addr (the address of text in core), not on addr (the
2939 offset between text in the .o file and in core). This change
2940 is from Peter Schauer.
2942 * main.c: Define ALL_CLEANUPS as a cast of zero.
2943 (return_to_top_level): Use it.
2944 (main): Do all cleanups after each command run as part
2945 of the gdb startup sequence. Also do all cleanups before
2946 entering the command loop, and every time we exit the command
2947 loop and reenter. Before, the cleanups from the startup sequence
2948 were being left undone until the first error!
2949 (command_loop): Rename do_nothing cleanup to command_loop_marker
2950 so we can see it easily when examining the cleanup chain.
2951 (init_signals): Add another do_nothing for signal handling.
2952 (quit_command): Only try to kill target if it has execution.
2953 Problems in the target stack got us into a state where
2954 inferior_pid was nonzero but none of the targets had execution.
2955 In this state you couldn't exit gdb.
2957 * dbxread.c: Two changes from Peter Schauer.
2958 (echo_command): Fflush output after an echo command.
2959 (show_history): Pass all args to cmd_show_list.
2961 * utils.c (init_malloc): Call mtrace to turn on tracing
2962 if the environment variable MALLOC_TRACE is set to a file name.
2963 * mtrace.c: Add source file which provides a log of every malloc,
2964 free, and realloc to a trace file.
2965 * mtrace.awk: Add source file which analyzes the trace file.
2966 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
2967 (VERSION): Roll to 3.94.3.
2969 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
2970 (check_duplicates): Don't bother with watchpoints.
2971 (set_raw_breakpoint): Comment about danger of this routine.
2972 (watch_command): Parse and eval all args before calling
2975 * solib.c (find_solib): Avoid error in referencing memory to
2976 see if any more shared libraries have been added. This is
2977 particularly useful if the target has terminated. Bug reported
2980 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
2981 in bringing up 3.94.2 on the Sun-3.
2983 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
2984 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
2985 expression (in scope) before reenabling watchpoint.
2986 * signame.c (init_sigs): Add missing declaration of i, fix
2987 sys_siglist declaration.
2988 * source.c (list_command): Fixed range computation to use
2990 * stack.c (backtrace_command): Do not allow command if target has
2991 no stack, print informative error message.
2992 * target.c (target_command): Do not write into command line
2993 because this fails if the target command is used in a user defined
2994 command. [This change was enhanced by gnu to support any-
2995 unique-prefix matching on target names.]
2996 * valops.c (value_struct_elt): Avoid infinite loop on an
2997 erroneous attempt to print the member of function (try p main.p).
2999 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3001 * expread.y (name_no_typename): Avoid reduce/reduce errors
3002 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
3003 Since the GDB parser really doesn't use name_no_typename in a
3004 name-only context, the parser can't tell the diff between
3005 names and numbers here. Avoid allowing a name_no_typename
3006 to be a NAME_OR_*INT to resolve the conflict.
3008 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3010 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
3012 * valprint.c (val_print_fields): bitfield printing didn't handle
3013 byte order. Indirect through a few more fns to cope.
3015 * values.c (modify_field): also cope with byte order.
3017 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
3019 Cleanup for release 3.94.2:
3021 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
3022 include files. Roll version to 3.94.2.
3024 * coffread.c (init_stringtab): Read length into unsigned char
3025 array before swapping; don't assume 32-bit longs.
3027 * target.c (target_info): Don't bother with get_sym_file, just use
3028 the symfile global variable.
3029 * symtab.h, symfile.c (get_sym_file): Delete it.
3031 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
3032 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
3033 (read_type): Replace one more error() with complain().
3035 * mipsread.c (parse_partial_symbols): Replace printf with complain.
3037 * i960-tdep.c: Fix copyright attribution.
3039 * config.gdb: Quote all backquotes in doublequotes. You can
3040 quote me on that. BSD 4.4 shell found this one.
3042 * infptrace.c (throughout): The third argument to ptrace is an
3045 * infrun.c (wait_for_inferior): When program has terminated, we
3046 have to call target_terminal_ours before we pop that target off
3047 the stack (e.g. before a call to target_kill or
3048 target_mourn_inferior). This fixes problem where a program
3049 terminates, then GDB stops for (tty output) and you have to type
3050 "fg" to the shell to resume it. FIXME: This code for what to
3051 do after termination really should be in normal_stop instead.
3053 * gdbcore.h (read_memory_check): Change declaration; it changed
3056 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
3057 4.4 prereleases, this avoids a bug in their sgtty compatability
3059 * remote.c: Use terminal.h rather than hand-rolling the same.
3061 * signame.c, signame.h (psignal): Arg is unsigned, not int.
3062 * utils.c (strsave, strstr): Fix arg types.
3063 * valprint.c (val_print): lint
3065 MIPS symbol table support from Per Bothner:
3067 * symfile.c (symtab_fns): Remove initializer table that needs to
3068 be hacked for each new symbol file format supported.
3069 (add_symtab_fns): New function, chains symbol table
3070 handlers into the global list.
3071 (symfile_init): Search this list.
3072 * symfile.h: Add next pointer, declare add_symtab_fns.
3073 * coffread.c (_initialize_coffread): Call add_symtab_fns.
3074 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
3076 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
3077 symbol *). Thus, we no longer need the hack to trash
3078 pst->filename. Good, since that hack confused code in symfile.c!
3080 (reorder_symtabs, destroy_all_symtabs): Removed static
3081 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
3082 Instead, the latter now uses a temporary array (stack-allocated
3083 from an obstack, and then freed).
3085 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
3086 haven't been set in the outermost stBlock of a procedure. This was
3087 a problem with f77 binaries on Ultrix 4.?.
3089 (new_symtab, new_symbol, new_type): Continue changing code to use
3090 obstacks more and otherwise conform to dbxread internal style.
3091 Made the free_code of symtabs be free_linetable (as in dbxread)
3092 instead of free_contents. This implies memory leaks when reading
3093 a new symbol table, until the conversion is finished. Did change
3094 (struct symbol) and (struct type) to be allocated on the
3095 symbol_obstack. Blocks and blockvectors are among the things
3098 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
3099 tested much, but it solved one problem (reported by Meissner), and
3100 cleans up some other things. The problem happened when an
3101 included file contains actual code (functions) and not just
3102 definitions. The mips coff is a little inconvenient there, since
3103 it may cause a procedure to be mapped to the wrong psymtab.
3105 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
3106 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
3107 this will need work for the new core paradigm.
3109 Opcode patches from the net:
3111 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
3112 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
3113 missing altogether - they are added here. From Bruce Bauman.
3114 * mips-opcode.h: The low mask for C0 instructions was too small.
3115 From Garrett Lau. I modified the fix to check the entire 32-bit
3118 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
3121 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3123 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
3125 * dbxread.c (read_type): Pointer subtraction (value_sub in
3126 valarith.c) sometimes failed because the types of the
3127 pointers being subtracted were not identical.
3128 These differed because dbxread.c was allocating pointer types
3129 using dbx_alloc_type+smash_to_pointer_type instead of
3130 lookup_pointer_type. I failed to find a justification for the
3131 former, so I changed it to use the latter. Similarly, I
3132 replaced smash_to_function_type by lookup_function_type,
3133 and smash_to_reference_type by lookup_reference_type.
3135 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
3136 _initialize_mipsread): corresponding changes.
3138 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
3140 * source.c (mod_path): Do tilde_expand on each component of the path,
3141 rather than on the (list of) paths as a whole.
3142 (print_source_lines): Set first_line_listed in addition to
3143 current_source_symtab and current_source_line. If the source was
3144 not findable, after a "dir" command to fix the problem,
3145 a "list" would get the wrong lines.
3147 While I was there... (gnu):
3149 * dbxread.c (read_type): Change error to complaint.
3151 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3153 First attempt at detailed understanding of symbol table memory alloc.
3155 * dbxread.c (dbx_symfile_read): Free our string table if we
3156 aren't the mainline. Free the "info" struct since we're done with
3158 (init_psymbol_list): Free any previously allocated psymbol lists.
3159 (): FIXME: Should realloc-down the psymbol lists when done reading
3160 the main symbol file?
3162 * symmisc.c (free_symtab): Free fullname field too.
3164 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
3165 (REGISTER_ADDR): Make result type unsigned int.
3167 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
3168 define REGEX must also define REGEX1 (its dependency).
3170 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
3172 * tconfig/i960: No longer works, points you at vxworks960 or
3175 * xgdb.c, XGDB-README: Remove file. Users can get the much
3177 * Makefile.dist: Remove all trace of xgdb.
3179 * breakpoint.c (breakpoint_1): Pass demangle arg to
3180 print_address_symbolic.
3181 (clear_breakpoints): Remove unused function.
3182 (breakpoint_re_set_one): Guts of breakpoint_re_set.
3183 (breakpoint_re_set): Use catch_errors to do them all anyway.
3185 * gdb-int.texinfo (Host versus Target): Add section on what is
3186 a "host" feature versus what is a "target" feature.
3188 * infcmd.c (path_command, path_info): Handle the PATH variable
3189 (object search path) as conveniently as the source search path.
3190 * environ.c (set_in_environ): Set some vars in GDB's environment,
3191 in addition to the child's. PATH, G960BASE, G960BIN for starters.
3192 * source.c (mod_path): New function, from guts of
3193 directory_command, modifies a path. Used by path_command.
3194 (directory_command): Call it.
3195 * defs.h (strsave): Declare.
3197 * utils.c (sevenbit_strings): Add new printing option.
3198 (printchar): Use it.
3199 (strsave): Provide this handy helper routine.
3200 (set_width_command): Rename set_screen_width_command.
3201 (_initialize_utils): "set screen-width" => "set width";
3202 "set screen-height" => "set height"; add sevenbit-strings.
3204 * infcmd.c (do_registers_info): Print floating point registers
3205 in raw hex as well as float format, regardless of whether it is
3206 a "virtual" convertible register.
3207 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
3208 regs as a double, just in case it's being used that way.
3209 * values.c (unpack_long): Comment on array/function coercion.
3210 (unpack_double): Argument is in target byte order now. For
3211 integer arguments, just call unpack_long and float the result.
3212 * m68k-tdep.c: include defs.h for "const" handling.
3213 * remote-nindy.c: Use ieee-float stuff.
3214 (nindy_fetch_registers): Unpack double regs to host double, then
3216 (nindy_store_registers): Pack extendeds to host double, flip
3217 around by misusing unpack_double, send as target double.
3219 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
3220 zero, as when stopped at the first instruction of a process.
3222 * blockframe.c: Fix filename in comment (param.h => tm.h).
3223 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
3224 * tm-68k.h: Fix typos.
3226 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
3228 Changes from a bringup on the DEC Vax under Ultrix 4.0.
3230 * coredep.c (fetch_core_registers): Pass end-address of register
3231 section to register_addr as expected. Don't call supply_register
3232 if we'd just pass it garbage.
3234 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
3236 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
3238 * target.c (push_target, target_info): Cast enums to int for < or
3241 * stack.c (print_frame_info): Identify source file & line
3242 even if we can't print it.
3244 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
3246 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
3248 Clean up IEEE floating point support.
3250 * ieee-float.h: New file.
3251 * ieee-float.c: Write real routines to convert between host
3252 doubles and various target IEEE extendeds.
3253 * m68k-xdep.c: Eliminate assembler code for extended floats.
3254 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
3255 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
3256 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
3257 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
3258 double_to_ieee_extended.
3259 * i960-tdep.c: Define ext_format_i960.
3260 * m68k-tdep.c: Define ext_format_68881.
3261 * sparc-tdep.c: Define ext_format_sparc, though unused.
3262 * Makefile.dist (HFILES): Add ieee-float.h.
3263 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
3266 Obsolete the "coffstrip" program in favor of using BFD's strip.
3268 * nindy-share/coffstrip.c: Remove file.
3269 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
3270 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
3271 * tconfig/nindy960: Remove reference to coffstrip.o.
3273 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
3275 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3277 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
3278 * dbxread.c: Remove static symfile_bfd.
3279 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
3281 * inftarg.c (child_detach): Pop the child_ops vector if the
3282 detach is successful.
3283 * remote-nindy.c (nindy_create_inferior): Don't push a new
3284 nindy_ops since nindy uses the same one for execution and memory
3286 * core.c (core_ops): Use child_attach and child_create_inferior
3287 rather than default attach and create_inferior functions.
3289 Handle floating point registers in core files.
3291 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
3292 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
3293 This version untested since BFD doesn't yet support sun3 core
3295 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
3296 conventions. Fix comments and style. This version has not
3297 been compiled yet, since we have no HP inhouse.
3298 * core.c (get_core_registers): Look for two sections, ".reg"
3299 and ".reg2", and pass both to fetch_core_registers sequentially.
3301 Revise directory path yet again.
3303 * source.c (forget_cached_source_info): Not static any more.
3304 (init_source_path): New default source path is "$cdir:$cwd".
3305 (dir_command): Handle variable arguments ($cdir, $cwd).
3306 (source_info): Print "Compilation directory" rather than
3307 "Originally compiled in" to remind people of $cdir.
3308 (openp): If the path contains $cwd, use current directory.
3309 (open_source_file): If compilation directory is known, replace
3310 first $cdir in path with the compilation directory.
3311 (print_source_lines): Even if we can't print the lines, set the
3312 current symtab and line for future commands like "info source" or
3313 "breakpoint". Also, error message now contains the file name,
3314 line number, and file access error message.
3315 (_initialize_source): Fix help text to describe changes.
3316 * main.c (cd_command): Forget cached source info when we chdir.
3317 * utils.c (strstr): Add simple implementation.
3319 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
3321 * coffread.c (read_one_sym, init_linetable, init_stringtab):
3322 Byte-swap COFF symbol tables if necessary when reading them in.
3323 Use complain() to replace error message in one spot. Needs
3324 corresponding change in bfd/coff-code.h to make some symbol
3325 swapping routines non-static.
3327 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3329 Merge changes from Eirik Fuller, for UTek.
3331 * defs.h (errno): Add declaration.
3332 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
3333 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
3334 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
3335 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
3336 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
3337 declarations of errno.
3339 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
3341 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
3342 <rpc/rpc.h> and <rpc/types.h>.
3344 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
3346 * i960-tdep.c (examine_prologue): Add new argument limit,
3347 which stops the scan at the end of the prologue, or at the PC.
3348 This fixes a problem where it walks down into the code for the
3349 user's statements if that code looks like function prologues.
3350 Mark Fox and I have been bouncing this code back and forth, making
3351 small changes to it. Callers changed to match.
3353 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
3355 Cleanup for gdb-3.94 release final:
3357 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
3358 the .c files from vx-share and nindy-share, from the various
3359 macros, since they are not found via ALLDEPFILES.
3360 (SFILES): Add tm-i960.h.
3361 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
3362 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
3364 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
3365 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
3367 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
3369 * am29k-tdep.c: Add contribution line.
3370 (examine_prologue): Cache information about function prologues in
3371 the misc-function-vector to avoid lots of references over the
3372 serial line while examining instructions.
3374 * core.c (core_close): New function made from cleanup_core.
3376 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
3377 remote-vx.c, remote.c, target.c, target.h,
3378 Update target_ops vector to add attach, close, and load entries.
3379 Use add_syms_addr_command, not add_file_addr_command, for
3380 add_file. Break out close routine from existing code.
3382 * dbxread.c (really_free_pendings): Don't free pending_blocks;
3383 they are in an obstack.
3384 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
3386 (define_symbol): Add symbol type parameter; change callers;
3387 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
3388 it to influence the symbol class on the i960.
3389 (define_symbol): Swap LOC_CONST's into target byte order.
3391 * exec.c (exec_close): New function.
3392 (exec_file_command): Call it.
3394 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
3395 Fix byte order of frame pointer.
3396 (read_var_value): Result of 0 if var's value can't be found,
3397 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
3398 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
3399 (locate_var_value): Use read_var_value and use its lazy address
3400 as the location of the var's value. Lint.
3402 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
3405 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
3406 obsolete Intel versions in favor of vxgdb versions.
3407 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
3408 code dealing with byte order of values, which Intel did in host byte
3409 order rather than gdb-4's target byte order.
3410 (i960_frame_chain_valid): Move to nindy-tdep.c.
3411 (examine_prologue, skip_prologue, frame_find_saved_regs,
3412 frame_args_address, leafproc_return, saved_pc_after_call,
3413 pop_frame): Add vxgdb versions from Mark Fox.
3414 (examine_prologue, frame_struct_result_address): Add code
3415 to deal with the saved value of G13 (struct return address
3417 (frame_args_address): Modify Mark's version to prefer the
3418 saved value over the current value in the topmost frame.
3419 Cache result in the frame info to avoid performance hair in
3421 (print_fault): Add gdb960 code for printing faults.
3422 (_initialize_i960): Actually call check_host.
3424 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
3425 add stub routines. FIXME, these currently just return zero!
3427 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
3428 (attach_command): Call target_attach, not target_open, now.
3430 * infrun.c (normal_stop): Make global, not static, for vx_attach.
3431 (child_attach): Rename from child_open.
3432 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
3433 don't confuse it with a zero step_resume_break_address.
3435 * inftarg.c (child_detach): Eliminate inferior_pid test.
3436 (child_files_info): Clean up message a bit.
3437 (child_ops): Use child_attach, not child_open, to attach.
3439 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
3440 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
3441 findvar.c to here, since it depends on the contents of the
3442 shadow_contents of breakpoints, but keep if #if 0 since it is
3445 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
3448 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
3449 (ptype_command, display_command): Eliminate have_inferior_p and
3450 have_core_file_p in favor of target_has_stack or
3451 target_has_execution.
3452 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
3453 code for actually finding the values of arguments, though we still
3454 keep track of the maximum stack offset for use in printing unnamed
3455 arguments. Handle missing FRAME_ARGS_ADDRESS.
3457 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
3458 (struct nindy_regs): Define registers passed to/from nindy.
3459 (nindy_fetch_registers, nindy_store-registers): Translate between
3460 nindy and GDB formats for the registers.
3461 (dcache_init): Statically allocate the cache, since it was being
3462 allocated by a malloc that was never freed anyway.
3463 (nindy_create_inferior): Error, not core dump, if no exec file.
3464 (nindy_before_main_loop): Use target_load, not target_add_file.
3466 * remote-vx.c (net_load): Specify large timeout for load
3467 requests. Allow user to break out with INTERRUPT.
3468 (net_break): Remove useless code, clean up. Change callers.
3469 (parse-args, skip_white_space, find_white_space): Clean up arg
3470 parsing to cope with quoted strings.
3471 (net_wait, net_quit): Never call error, just return status.
3472 (vx_read_register, vx_write_register): Cleanup status checking.
3473 #ifdef the code based on which CPU we are using (960 or 68k),
3474 FIXME, this should be completely general but it isn't yet.
3475 (vx_xfer_memory, vx_resume): Cleanup status checking.
3476 (vx_run_files_info): Improve message.
3477 (vx_load_command): Renamed from vx_add_file_command. Allow load
3479 (net_ptrace): Remove unused routine.
3480 (vx_wait): Adopt code from vxgdb960 to cope with broken
3481 connections to target machine and prompt to disconnect. Remove
3482 debug printouts. Map some EVENT_'s to SIGnals.
3483 (add_symbol_stub, vx_open): Print names of object files we found,
3484 and "ok" if we read their symbols OK. Clarify output in general.
3485 (vx_attach, vx_detach, vx_kill): Add these commands.
3486 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
3487 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
3488 "info files" output, and create_inferior, since we already have
3491 * stack.c (frame_info): Replace Frame_unknown with 0.
3492 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
3493 (return_command): Pop until the PC matches as well as the FP,
3494 so it works even if the FP is shared with another function,
3495 as in "frameless" or "leaf" procedures.
3497 * symfile.c (load_command): renamed from add_file_target_command.
3498 (add_syms_addr_command): renamed from add_file_addr_command.
3499 (add_syms_command): Stub to call target_add_syms.
3500 (_initialize_symfile): Change command names and descriptions,
3501 add-file => add-syms, and load from alias to its own command.
3503 * target.c (kill_or_be_killed, maybe_kill_then_attach,
3504 maybe_kill_then_create_inferior): Default for attempts to start
3505 a process, if one is already running, is to ask about killing
3506 it and retry if yes.
3507 (upstack_create_inferior): #if-0 it, strata obsolete it.
3508 (push_target, unpush_target, pop_target): to_close() a target
3509 before unstacking it.
3510 (target_info): Renamed from target_files_info.
3511 (_initialize_targets): Rename "i files" as "i target", accessible
3514 * target.h: Improve comments about the target_ vectored routines.
3516 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
3517 Convert commenting style to standard GNU style.
3518 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
3519 (SKIP_PROLOGUE): No longer a no-op.
3520 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
3521 (*_REGNUM): Sort register numbers.
3522 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
3523 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
3524 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
3525 are now 10 byte extendeds, not 8 byte doubles.
3526 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
3527 for nindy versus vxworks targets. FIXME, this should possibly go
3528 in the target vector.
3529 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
3530 frame_saved_regs and arg pointer with each frame.
3531 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
3532 (FRAME_ARGS_ADDRESS): Use cached result.
3533 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
3534 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
3535 (PRINT_RAMDON_SIGNAL): Call print_fault.
3536 (POP_FRAME): Now works.
3538 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
3539 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
3540 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
3541 (ADDITIONAL_OPTION_HANDLER): use target_load, not
3544 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
3545 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
3547 * valarith.c (value_subscripted_rvalue): Avoid handling
3548 floats and doubles specially; it gave alignment errors. Lint.
3550 * valops.c (value_of_variable, value_of_this): Error if unknown
3553 * valprint.c (print_floating): Bcopy rather than pointer-deref,
3554 to avoid alignment problems.
3555 (value_print): Handle unknown value address.
3556 (cplus_val_print): Two args are ignored; remove them. Change caller.
3557 (val_print): Use unpack_long rather than pointer-deref.
3560 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
3561 to avoid alignment problems.
3562 (value_being_returned): Error if return value unknown.
3563 (set_return_value): Add bogosity warning, FIXME. *
3565 * TODO: A woman's work is never done.
3567 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
3568 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
3569 Add ieee-float.o to OBS.
3570 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
3571 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
3572 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
3574 Changes to generalize the VxWorks RPC protocol slightly, to handle
3575 i960 as well as 68000.
3577 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
3578 * vx-share/reg.h: Produce i960 regs #ifdef I80960
3579 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
3580 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
3581 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
3582 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
3583 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
3584 so they will move in target byte order rather than network
3585 byte order (happens to be the same).
3587 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
3589 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
3591 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
3594 Add contribution lines to various files, showing where they
3597 * breakpoint.c (break_insn, check_break_insn_size,
3598 read_memory_nobpt): Remove to mem-break.c.
3600 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
3603 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
3604 entry has bad register number. This change is not
3605 tested in this release, FIXME.
3607 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
3610 * value.h: Force value's contents field to be aligned to hold
3611 at least a double or a long long (if supported). This avoids
3612 doing bcopy's in and out of the contents field.
3614 (step_1): Avoid coredump under obscure circumstances when we
3617 * symtab.h (misc_info): Add field to misc function vector for
3618 any kind of cached information the target code desires. AMD
3619 29000 uses this to avoid repeating examine_function_prologue's.
3621 * coffread.c: Lint. Remove static symfile, read_section_header.
3622 core.c (have_core_file_p): Lint: remove.
3623 expprint.c (print_subexp): Lint.
3624 infptrace.c, valops.c, valprint.c: lint.
3626 Roll in changes from vxgdb-5.0.1:
3628 * symtab.h: Comment byte order of each address class. Add
3629 LOC_LOCAL_ARG for frame-relative args (960).
3630 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
3631 symtab.c, symmisc.c: ditto.
3633 * infrun.c (init_wait_for_inferior): Clear stop_signal.
3635 * remote.c (remote_resume): Error if resume with a signal.
3637 * symfile.c (prim_record_misc_function): Clear misc_info.
3638 (fill_in_vptr_fieldno): Check stub type of arg.
3640 * valops.c (value_cast): Avoid looking up names of types whose
3641 name we don't know, to prevent coredump. Sun CC produces typedef
3642 rtx and the name of *rtx is zero...
3644 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3646 Roll in changes from final AMD 29000 port (Tiemann).
3648 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
3649 for ../include/a.out.encap.h. This might not work now that BFD
3650 is separately compiled. Instead, BFD support for encap will have
3651 to translate machine type 29k into the right COFF_MAGIC.
3653 * infcmd.c: Remove references to inferior_pid that aren't used
3654 in actual ptrace calls; use target_has_execution, etc.
3655 (have_inferior_p): Remove function.
3656 (program_info): Print target info rather than "process number";
3657 avoid gratuitous messages unless from_tty.
3658 (run_stack_dummy, finish_command): Set proceed_to_finish.
3659 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
3660 main.c: Lint. Lose have_inferior_p().
3661 inferior.h (have_inferior_p): Remove, lint.
3662 (proceed_to_finish): Add flag to ask that all regs be saved
3663 by normal_stop, for the few commands that need it, speeding up
3664 serial I/O. Add comments to stop_registers.
3666 * remote-eb.c: Remove newline from breakpoint message we grep
3667 for. Never time out when running the user program.
3671 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3673 Roll in changes from vxgdb-5.0.1:
3675 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
3676 symbol in its raw form, we are processing an unlinked ".o" file.
3677 See if the target environment has assigned it an address, using
3678 target_lookup_symbol (VxWorks does), and enter it into the symtab
3681 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
3682 68k versions for a simpler version that assumes zero FP at bottom.
3683 Fixes bug of truncated stack reports.
3685 * target.h (target_lookup_symbol): Define this routine's args
3686 and result, finally.
3688 * target.c (nosymbol): Default routine for target_lookup_symbol.
3689 (target_default): Default lookup_symbol and call_function too.
3690 (files_info): Only print has_all_memory warning if a non-dummy
3693 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
3694 vx_convert_from_virtual): If target does not have floating point,
3695 zero register "values", and avoid doing cross-net conversions.
3696 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
3697 (vx_open): Rearrange code that attaches to target and reads
3698 symbols for all loaded modules, to work if some of the modules
3699 are not accessible. Add symbol_stub() and add_symbol_stub()
3700 as callbacks from catch_errors(). Allow connect attempt to be
3701 interrupted painlessly with ^C (FIXME, there are still some bugs
3702 if the interrupt happens during symbol reading.). Print
3703 final message with puts_filtered, since symbol messages are
3708 * main.c (catch_errors): Only print errstring if non-null.
3709 (command_loop): Avoid an ioctl per command to test ISATTY.
3711 * remote-vx.c (net_load): make static; avoid sophomoric msg.
3712 (vx_xfer_memory): Return correct result!
3713 (vx_files_info): Indicate whether target has float or not.
3714 (vx_lookup_symbol): Complain, not error, if target gone.
3715 (vx_open): Print "Connected" msg before disabling immediate-quit.
3716 [FIXME: lookup_symbol and vx_open changes need testing.]
3718 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
3719 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
3720 contributor lines and update copyrights to 1991.
3722 Changes from an attempted H-PUX host port:
3724 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
3725 defines PT_ATTACH and PT_DETACH but not PT_KILL.
3726 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
3727 * remote-vx.c: include <sys/time.h> for HPUX.
3728 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
3729 "core_file_command" routine to BFD regime. May not work yet.
3731 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
3733 * xgdb.c: Replace X10 version with some VJ version.
3734 (FIXME: Its copyright assignment is not on record.)
3735 * xgdb.c: Update include files to X11R4 (Xaw crud).
3736 (xgdb_display_source, create_text_widget): fix call to
3737 get_filename_and_charpos. Rewack source window stuff for X11R4
3738 (gleaned from include files, and "nm's" of binary libraries, since
3739 I had no doc available).
3740 (append_selection, append_selection_word): Disable with FIXME
3741 since R4 changed interface here.
3742 (create_buttons): Add back the old set of buttons.
3743 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
3745 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
3746 Roll VERSION to 3.94 (not yet final though).
3748 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3750 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
3751 obstack_int_grow, obstack_int_grow_fast): Eliminate
3752 cast on left of assignment, which gives MIPS cc fits and is
3755 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
3756 F_ALIAS. Use printf, not fprintf, when not passing a file
3758 (compare_opcodes): Check that identical instructions have
3759 identical opcodes, complain otherwise.
3761 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
3762 was reported by Roland McGrath.
3763 (unimp): Only match if exactly zero instruction. (Roland)
3764 (branches and traps): Generate all variations of these
3765 instructions with macros, based on a single call that defines
3766 each condition name and its binary representation.
3767 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
3769 * valprint.c (val_print_fields): Take, and use, format parameter.
3770 This means that "p/x struct" again prints the elements in the
3771 desired format. Changed callers.
3773 * stack.c (frame_info): Use filtered output, and indicate wrap
3774 points. Remove kludgy formatting designed to avoid line wrap.
3776 * utils.c (wrap_here): If the line is already full (because
3777 we had printed a long indent or long wrapped string), do an
3778 immediate newline-and-indent.
3780 * m68k-pinsn.c (print_insn_arg): Bugfix from
3781 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
3782 instruction is incorrectly disassembled as bkpt #8.
3784 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
3785 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
3786 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
3787 and then will dump core (sometimes). I traced it back to an
3788 uninitialized symfile_name in psymtab_to_symtab.
3789 (const_vol_complaint): Add quotes to message.
3790 (define_symbol): Only believe line number if gcc_compiled.
3791 Avoid allocating symbol if we will not return it.
3793 Add target strata support so that newly established targets go
3794 into their right place in the target stack (e.g. a new exec file
3795 doesn't wipe out the ability to access the running process).
3797 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
3798 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
3799 and initialize it properly in all the targets.
3801 * target.h: Document strata. Change return type of push_target.
3803 * target.c (nomemory): new function for dummy memory access.
3804 (tcomplain): Rename complain, now also used in symfile.c.
3805 (push_target): Push targets within strata. New return value shows
3806 whether new target is on top of stack or not. Always keep dummy
3808 (target_files_info): Ignore dummy target.
3810 * core.c (core_open): Warn user, and skip accessing file, if the
3811 core target is not the topmost target in the stack.
3812 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
3815 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
3816 target_ops, it doesn't belong there since we have no regs there.
3817 Change name of target from machine => memory to clarify.
3819 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
3821 * Freeze version 3.93 for release.
3823 * Makefile.dist: Handle vx-share and nindy-share subdirs
3824 properly when building gdb.tar.Z.
3826 * symtab.c: lint; add no_symtab_msg to consolidate the messages
3827 printed in various places, so I could change just one copy.
3829 * dbxread.c, coffread.c: Change references to bfd->iostream
3830 to cast to FILE *, now that BFD avoids needing types defined
3831 in other header files.
3833 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3835 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
3836 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
3837 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
3838 (actually gcc -Wall).
3840 * dbxread.c: Remove first_global_sym, last_global_sym, since
3841 they are never referenced.
3843 * defs.h (baud_rate): Declare.
3844 main.c: Define it, and add the -b option to set it.
3846 * gdb-int.texinfo: Add text on how to define a new host or target
3847 architecture, prompted by Per Bothner's questions about MIPS
3850 * gdb.texinfo: Document "complaints". Change doc of -q since
3851 gdb no longer prints the copyright and blurb if you specify a file
3852 name to be debugged (just like Emacs). Add doc for Nindy-specific
3853 command line flags for specifying target serial port and such.
3854 Update copyright to 1991.
3856 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
3857 has taken over for us the job of ripping up executable files. The
3858 crud caused Per Bothner's port to not compile.
3860 * infrun.c (normal_stop): Avoid printing "Program exited
3861 normally" if we are in batch mode. This allows a GDB which
3862 executes a program on a target system, to behave like a Unix
3863 command (input from stdin, output to stdout, no extraneous
3866 * main.c (main): Allow additional machine-dependent command line
3867 options to be specified with the ADDITIONAL_OPTIONS,
3868 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
3869 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
3870 processing to occur just before the main loop with
3871 BEFORE_MAIN_LOOP_HOOK.
3872 (main): If a "core file" argument is specified, and it is not a
3873 core file, try it as a process ID to attach.
3874 (symbol_completion_function): Attempt to cope with
3875 "show screen-" TAB, not very successfully. This needs more work,
3877 (batch_file): New function, returns whether we are reading
3878 commands from an interactive tty on stdin, or from somewhere else.
3879 Called by normal_stop since it doesn't get from_tty passed down
3880 to it like many commands do.
3882 * remote-nindy.c: Handle command line options for nindy
3884 (nindy_before_main_loop): Prompt user for tty name if they
3885 don't specify it before getting to the interactive command loop.
3887 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
3888 and -r command line options. Also add hook before main loop
3889 to make it easy to specify a tty.
3891 * TODO: More things to do, one done.
3893 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
3895 * dbxread.c: Make complaint() calls pass pointer, not struct.
3896 Add complaints about badly formatted C++ type information
3897 (const/volatile indicator, and parse errors resulting in
3898 error_type). Fix C++ virtual member fn comment.
3899 (read_struct_type): Avoid bumping pointer if we got a parse
3900 error; this prevents our walking beyond the end of a string.
3901 Terminate loop on null char as well as semicolon.
3902 (process_one_symbol): Fix the LBRAC fix so that it uses the
3903 last previous SLINE, FUN, or SO record's PC address. C++ debug
3904 symbols did not have SLINE records in a useful order compared
3905 to the LBRAC records.
3906 (define_symbol): Handle "catch" records.
3908 * symtab.c (check_stub_type): Added new complain
3909 `stub_noname_complain' and added a consistency check to
3910 keep the debugger from crashing when finishing from an
3911 exception frame. A real fix will be needed later.
3913 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
3915 * infcmd.c (attach_command): Make global.
3917 * Makefile.dist (REMOTE_OBS): Make these compile by default,
3918 but make them easy to comment out. Perhaps later they should
3919 be enabled by what CPU you configure for? FIXME.
3920 (VERSION): Roll to 3.93.
3921 (pinsn.o): Remove rule for obsolete file.
3922 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
3924 Run down a problem that manifested by printing the wrong function
3925 name in stack traces of read_ofile_symtab. Turned out that the
3926 problem was the SunOS 4.1.1 (and previous) C compiler outputs
3927 the LBRAC symbol with an address in the *data* segment, which
3928 blew our binary search through the blocks.
3930 * dbxread.c: Use the complain() facility consistently to bitch
3931 about problems in the symbol file we are reading.
3932 (finish_block): Add code to check the nesting of the blocks;
3933 complain and Procrust them to fit if wrong.
3934 (make_blockvector): Check the order of the blocks, complain
3935 [but don't cope] if wrong.
3936 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
3937 symbols to be sure their PC value is greater than the last SLINE
3938 (line number) symbol we've seen, complaining and adopting the
3939 SLINE PC value if wrong.
3941 * symfile.h (struct complaint, complaint_root, complain,
3942 clear_complaints): Add.
3943 * symfile.c (complain, complaint_root, clear_complaints): Add
3944 facility to deal with non-fatal complaints and to regularize their
3946 (symbol_file_add): Clear complaint counters to allow new complaints.
3947 (initialize_symfile): Add 'set complaints' and 'show complaints'.
3949 * dbxread.c (dbx_symfile_read): Remember the address and size
3950 of the string table for the main symbol file, so we won't read it
3952 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
3953 to avoid reading the string table yet again. Lint.
3954 (throughout): Improve filtered output, including word wrap.
3955 (read_range_type): Improve Bothner's fix to handle other types too.
3957 * utils.c: Improve line wrap implementation. Handle unlimited
3958 width by making chars_per_line unsigned.
3959 (puts_filtered): New, easy, function.
3961 * defs.h (puts_filtered): add.
3963 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
3964 call the identical sort_symtab_syms() in symfile.c instead.
3966 * expread.y: Suggest the `file' command rather than `symbol-file'.
3968 * command.h (enum var_types): Add zinteger for seroable
3970 * command.c (do_setshow_command): Handle var_zinteger. Restructure
3971 nested if's into a switch.
3973 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
3974 we did not stop because of a breakpoint (it must have been for
3975 some other reason, like a "stepi"), so don't print anything.
3977 * symtab.c: Include <sys/types.h> all the time. Now that BFD
3978 doesn't include <sys/types.h>, old SunOS's require it for
3981 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
3983 A test port of gdb-3.92.6 to the Sony NEWS.
3986 Don't normally link in remote- or vx stuff.
3987 Some of it doesn't compile, and it wastes space for 99% of the users.
3988 Remove reference to no-longer-used HAVE_VPRINTF.
3989 Fixed BFD_DEP typo to BFD_DIR.
3991 Fix cast in arg to bfd_h_getlong.
3992 Make char *prefix be const.
3993 Fix how certain range types are mapped into builtin unsigned int types.
3995 Remove 2 #includes. They cause errors (on Sony, at least),
3996 and aren't needed (they wern't in earlier versions).
3998 print_address_symbolic should never demangle labels
3999 (since it prints *assembler-level* labels).
4001 [This was superseded by the change to printcmd below.]
4004 Add some "volatile" return types to avoid warnings.
4005 If MISSING_VPRINTF add vprintf function and not just macro
4006 (since vprintf is used in printcmd.c).
4008 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
4009 (The latter isn't grokked by some PCC-based compilers.)
4011 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
4013 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
4014 * nindy-share/coffstrip.c
4015 Added some forward declarations (otherwise, gcc complains
4016 about implicit extern redefined as static).
4018 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
4020 Changes inspired by Per Bothner:
4021 * printcmd.c (print_address_symbolic): Take additional parameter
4022 specifying whether to demangle.
4023 (print_address): Pass in asm_demangle to control demangling.
4024 (print_address_demangle): New fn, takes explicit arg to control
4026 * utils.c: Add new vars demangle and asm_demangle, and let them
4028 (fputs_demangled): If !demangle, just print the argument.
4029 (fprint_symbol): If !demangle, just print raw symbol.
4030 * valprint.c (val_print): Call print_address_demangle rather than
4031 print_address, to cause demangling to depend on the global
4032 rather than assembler-level demangling setting.
4033 * WHATS.NEW, gdb.texinfo: Document.
4035 * main.c (show_command): Show all settings if no arg.
4036 (initialize_main): Make "info set" the same as naked "show".
4037 * command.c (cmd_show_list): Handle prefix commands in the
4038 list, and print the name of the setting as well as its English
4039 description and value.
4041 Allow gdb functions to specify where a line should wrap if it
4042 exceeds the size of a terminal line. Use it to make the output
4044 * utils.c (set_screen_width_command): New fn, mallocs a buffer
4045 of the right size when screen width changes.
4046 (set_screensize_command, screensize_info): Remove #if 0'd fns.
4047 (wrap_here): New fn, indicates a point in the output where we
4048 should wrap the line rather than just letting it overflow at a
4050 (fputs_filtered): Implement wrapping.
4051 (n_spaces): New fn, returns a pointer to N spaces.
4052 (print_spaces_filtered): Use n_spaces.
4053 * defs.h (n_spaces): Declare.
4054 * stack.c (print_frame_info): Wrap with 4-space indent after
4055 fn name and before filename and line number.
4056 * printcmd.c (print_frame_args): Wrap with 4-space indent
4057 before each argument name is printed.
4058 * valprint.c (value_print): Wrap with no indentation before
4060 (val_print_fields): Wrap with indentation relative to nesting
4061 level before each field name.
4062 (val_print): Wrap with nesting indentation before array elements.
4063 * command.c (do_setshow_command): Avoid extra newlines,
4064 wrap with 4-space indent around values printed, end with period.
4065 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
4067 * breakpoint.c (breakpoint_1): Implement addressprint for
4068 "info breakpoints" display. Change file name and line number
4069 format to " at file:nnn" rather than " (file line nnn)".
4070 * gdb.texinfo: Document.
4073 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4075 Frozen for gdb-3.92.6 release.
4077 README, WHATS.NEW: Update for 3.92.6 release.
4079 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
4080 coffread.o from configs since it is now built by default.
4081 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
4082 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
4083 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
4084 from configs since it is now built by default.
4086 Makefile.dist: Update for release 3.92.6. Handle files that
4087 have been moved to ../include, ../getopt, or ../bfd. Add
4088 saber.suppress and tests directory. Add config.status to
4089 the release (it will say "none").
4091 coredep.c: Minor formatting fixes.
4093 These changes were made in early December but only checked in now:
4094 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
4095 nindy-share/nindy.c: lint
4096 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
4097 register values coming back from the target; we store values
4098 in target byte order everywhere.
4100 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
4102 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
4104 * valprint.c (cplus_val_print, val_print_fields): New functions,
4105 which print C++ objects. They conspire to avoid printing a
4106 virtual base class more than once, following all the twists and
4107 turns of C++ virtual base rules.
4108 (val_print): Call the above rather than do it by hand.
4110 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
4111 symbol file, not for added files like shared libs. This really
4112 needs to be generalized to a timestamp per file.
4114 * core.c (cleanup_core): Avoid coredump if no core file.
4116 * config.gdb: Accept -host or -target in place of +host or
4119 * coffread.c (find_linenos): Avoid desupported BFD interface
4120 to line numbers. We still read them manually rather than using
4121 BFD's "generic" features.
4123 * gdbrc.tex, threecol.tex: Add GDB reference card and its
4125 Makefile.dist: Add refcard to OTHERS list for creating tar files.
4127 * Makefile.dist: Eliminate use of $< in explicit targets.
4129 * readline/Makefile: Use $< rather than $*.c, which does not
4130 include the VPATH in GNU Make.
4132 * tconfig/i960-bout, tconfig/i960-coff: These are identical
4133 copies of tconfig/i960, added for global configuration
4134 compatability. All i960 versions can read both coff and b.out.
4136 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
4137 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
4140 * TODO: Think of more things to do.
4142 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
4144 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
4145 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
4146 64-bit float conversion.
4148 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
4149 equivalent to sun?os4 so global config works.
4151 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
4153 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
4155 * main.c: Only declare linesize once; declare pagesize not at
4156 all, since it is never used.
4157 (main): Clear newly allocated line before it is used.
4159 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
4161 Further stabilization for the Intel 960.
4163 * Makefile.dist: Parameterize the location of the "include"
4164 and "bfd" directories, as well as "getopt". Add symfile.c.
4165 Link in both dbxread and coffread. Fix up "make depend" to
4166 rewack the locations of include, bfd, and getopt in its output.
4168 * README: Document moving include files, improve some of
4171 * coffread.c: Move common code out to symfile.c. Change
4172 symbol_file_command style interface to use new *_symfile_init
4173 and *_symfile_read interface under BFD. Use BFD internal
4174 info to locate line table, symbols, etc.
4176 * core.c (core_fetch_registers): Rename to get_core_registers
4177 to avoid confusion with fetch_core_registers.
4178 (register_addr): Move to coredep.c, which is already machine
4179 dependent. This leaves core.c pretty clean of dependencies.
4181 * coredep.c (register_addr): Accept this routine from core.c.
4183 * dbxread.c: Move common code (with coffread.c, etc) into new
4184 symfile.c. Each psymtab now contains a pointer to the
4185 format-dependent function that knows how to read it in. Make
4187 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
4188 (process_one_symbol): Add code to complain about a "compiler bug
4189 we muzzle here", if we actually see it.
4191 * eval.c (evaluate_subexp): Insert missing "break" statements
4192 in code that determines whether a variable is an lvalue in
4193 memory, register, or whatever. I detected this via a compiler
4194 bug in which it *almost* mashed out the whole switch statement.
4196 * gdb-int.texinfo: Add minor sections on configuring gdb for
4197 release, and about the README file.
4199 * infcmd.c (registers_info): Fix formatting somewhat. Still
4200 not as pretty as before, but it handles byte swapping.
4202 * remote-nindy.c: If data cache routines are interrupted while
4203 waiting for the remote end, be sure that any uninitialized cache
4204 blocks are on the free list, not on the valid list!
4206 * symfile.h: Flesh out this header file with all the various
4207 routines and variables that have been merged in from dbxread.c
4208 coffread.c, and symtab.c to symfile.c.
4210 * symfile.c: New file, containing code common to dbxread.c,
4211 coffread.c, and some code from symtab.c. All generic code for
4212 reading symbol files should be in here now.
4213 (unrecord_misc_function): Remove unused function.
4215 * symtab.h: Remove file-reading things to symfile.h.
4217 * symtab.c: Remove file-reading things to symfile.c.
4219 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
4220 to decode i960 fault types.
4222 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
4223 target.c: Change type of the "resume" function from int to void,
4224 since its result was never used.
4226 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
4228 * main.c: Replace "stupid" with "caution"; you now "set caution
4231 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
4233 * infcmd.c (do_registers_info): Call val_print to deal with the
4234 byte order of the registers being printed. FIXME, this makes
4235 the formatting of the output uglier.
4237 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
4238 defined, call it for signals the debugger doesn't itself use.
4239 The i960 uses this for more detailed fault information.
4241 * remote.c (remote_open): If arg is null, print help rather than
4244 * sparc-xdep.c (register_valid): Avoid declaring size, since
4245 various modules will think of various sizes depending on the
4246 architecture of their tm-file. FIXME, we need protection against
4247 actually entering one of those modules, which would clobber
4248 storage if not for the target architecture compiled into gdb.
4250 * stack.c (up_command, down_command): Always print the frame
4252 (up_silently_command, down_silently_command): New commands
4255 * i960-pinsn.c (reg), i960-tdep.c: Lint.
4257 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
4258 more parameters than it used to.
4260 * findvar.c (registers): Increase slop to 256 bytes, which should
4261 protect us against even most RISC machines with large register
4263 (locate_var_value): Move declaration inside related ifdef.
4265 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
4266 throughout, to avoid throwing away buffered input from the board.
4267 (nindy_wait): Supply_register takes addr_of_value, not value.
4268 (i960_print_fault): Renamed from i80960_fault.
4269 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
4270 (nindy_store_registers): Avoid regs_changed stuff, just stuff
4272 (nindy_create_inferior): Don't bother to write PC_REGNUM since
4273 we can set the PC in the call to proceed(). Unpush nindy_ops
4274 before pushing it on top, to avoid message to user. Eliminate
4275 commentary from Unix machines that just misleads here.
4276 (reset_command): Fix error message to suggest target command.
4278 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
4280 Release 3.92.5 as frozen.
4282 Stabilize the merged release...with help from lint, Saber C,
4285 Everywhere: Add include files needed to declare return types
4286 of functions called.
4288 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
4290 * breakpoint.h: Add undeclared breakpoint functions, and some
4291 functions for display handling since I couldn't think of a better
4294 * breakpoint.c (insert_breakpoints): Make code for disabling
4295 shared library bkpts more likely to work. It's used when we
4296 rerun a program and stop before the shared library has been
4298 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
4299 cast from pointer, so it squeezes through catch_errors.
4300 (bpstat_stop_status): Fix logic broken some time ago. We now
4301 always create a bpstat if the stop address matches a breakpoint,
4302 even if we don't stop there -- just like the old code used to do
4303 before I got my fingers into it (sigh).
4304 (breakpoint_1): Print "ignore count" after "stop only if"
4305 condition, since that's how it actually works.
4306 (mention): Handle watchpoints as well as breakpoints.
4307 (watch_command): use set_raw_breakpoint and mention to do most
4308 of the work (and initialize all the fields!). Only pass one
4309 arg to parse_c_expression, since that's all it takes.
4311 * command.c (not_just_help_class_command): Rename arg to args
4312 since we ignore "unused argument" warnings on vars named "args".
4313 inflow.c (child_terminal_info): ditto.
4314 infptrace.c (kill_inferior): ditto
4315 main.c (catch_errors, version_info, quit_command, pwd_command,
4316 source_command, dump_me_command, editing_info,
4317 set_history_size_command, set_history, show_history,
4319 stack.c (locals_info): ditto
4320 target.c (target_files_info): ditto
4321 valprint.c (set_input_radix, set_output_radix): ditto
4323 * core.c: Remove old variables for handling core and exec file
4324 sections (data_start, data_end, stack_start, stack_end,
4325 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
4326 text_end, exec_data_start, exec_data_end, text_offset,
4327 exec_data_offset, data_offset, stack_offset). They're
4328 superseded the more general build_section_table and
4330 (get_exec_file): Mention the `file' command.
4331 (read_memory_check): Rename to memory_error, and only call it
4332 in the case of an actual error.
4333 (read_memory, write_memory): call memory_error.
4334 (core_fetch_registers): Register section name is ".reg".
4336 coredep.c: Remove a bunch of crud now that all this file does
4337 is pull the registers out of a core file.
4338 (fetch_core_registers): Rewrite to actually work, I hope.
4340 dbxread.c: Use a.out.gnu.h, not system a.out, now.
4341 Replace index() with strchr(). Remove all the pre-BFD macro
4342 definitions for accessing the symbol file.
4343 (struct dbx_symfile_info): Encapsulate the information that
4344 dbx_symfile_init needs to pass to dbx_symfile_read in this
4347 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
4348 dbx_symfile_discard): Rearrange symbol file reading to divide
4349 the format-specific part from the format-independent part,
4350 leaving the format-independent part such as file name expansion
4351 and opening in symtab.c. This replaces
4352 partial_symbol_file_open and partial_symbol_file_read.
4353 Symbol_file_read, add_file, add_file_target_command,
4354 add_file_addr_command move to symtab.c. Pass an explicit
4355 "mainline" flag for when reading the main symbol table, rather
4356 than relying on the offset address to be zero or nonzero.
4358 (dbx_symfile_read): Don't allow void *'s to be printed as
4360 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
4361 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
4362 macro" debug version really work.
4363 (read_dbx_symtab): Remove unref'd parameter inclink.
4364 Avoid swapping N_SLINE symbols, for speed.
4365 Merge N_TEXT!N_EXT case with the other external symbol
4366 definitions' case. Add comments.
4367 (start_psymtab): Allocate the symfile name in the psymtab on
4368 the psymbol_obstack, rather than using the caller's storage.
4369 (end_psymtab): Only allocate a dependencies list if there are
4371 (psymtab_to_symtab_2): Use BFD when reopening file to read
4372 its symbols for real.

4375 (read_huge_number): Add FIXME about overflows.
4376 (read_range_type): Add FIXME about comparing a long to 1<<32.
4378 * coffread.c: Minor changes to move things closer to the new
4379 regime with symtab.c and dbxread.c Major work is still needed
4382 * exec.c (exec_file_command): Remove old variables (see core.c
4384 (xfer_memory): If memory transfer is right at the end of a
4385 section, don't lose.
4387 * findvar.c (get_saved_register): If value is in a real
4388 register, LVAL is lval_register, not lval_memory.
4390 frame.h: Declare print_sel_frame and record_selected_frame.
4392 gdb-int.texinfo: New file, for GDB internals documentation.
4393 Very simple, unformatted doc of cleanups is there for now.

4396 section addresses and offsets. (See core.c above.)
4397 Declare fetch_core_registers and registers_fetched.
4399 getopt.c: Declare char *alloca(); even on SPARC.
4401 infcmd.c (run_command): Call target_kill rather than
4403 (step_command, next_command, stepi_command, nexti_command):
4404 Declare from_tty parameter even though we don't use it.
4405 (run_stack_dummy): argument BUFFER is a char array, not
4406 a pointer to REGISTER_TYPE.
4407 (finish_command): using_struct_return needed a value *,
4408 not a struct symbol *.
4410 * infptrace.c (child_xfer_memory): To avoid dependency on
4411 where sections are in memory, try PT_WRITE_D and if that fails,
4412 try PT_WRITE_I. Most Unixes don't care which you use.
4414 * infrun.c (step_resume_break_shadow): Change to array to
4415 match other breakpoint shadow storage.
4416 (clear_proceed_status): Pass address of bpstat to
4417 bpstat_clear, not the bpstat itself.
4418 (child_create_inferior): FIXME comment about if the child
4420 (start_inferior): Remove old function.
4421 (child_open): Use target_kill rather than kill_inferior.
4422 (wait_for_inferior): Ditto.
4423 (insert_step_breakpoint, remote_step_breakpoint): Use
4424 new step_resume_break_shadow.
4426 * inftarg.c (child_wait): If all child processes die,
4427 pretend that the one being waited for exited with signal 42.
4429 * main.c (command_line_input): When scanning for comments,
4430 don't coredump on unclosed quotes.
4431 (quit_command): Use target_kill rther than kill_inferior.
4432 (_initialize_main): Rename class_user from "user" to
4435 * printcmd.c (print_command_1): Initialize "fmt" if no format
4436 is specified by the user.
4437 (print_frame_args): Only add to args_printed if we are
4438 actually fetching args from the stack (avoiding undefined
4440 (_initialize_printcmd): Remove bogus \{ from string.
4442 * remote-eb.c (eb_open): Avoid coredump on no argument.
4444 * remote-nindy.c: Bring out of Intel environment into new
4445 target environment. Remove all conditional compilation on
4446 I80960. Massive hacking throughout.
4447 (nindy_xfer_inferior_memory): New routine stolen from
4449 (nindy_create_inferior): New routine pieced together, probably
4450 not quite working yet.
4451 (nindy_ops): New target_ops struct for nindy.
4453 * remote-vx.c: Use write_memory rather than target_write_memory
4454 to get error checking.
4455 (vx_add_file_command, vx_open): Use symbol_file_add rather than
4457 (vx_create_inferior): Use target_terminal_ours...
4459 * signame.c (_initialize_signame): Always initialize, since
4460 we need the table for things other than psignal.
4462 * solib.c (solib_add): Use symbol_file_add, not add_file.
4463 (solib_address): Return boolean result rather than struct
4464 pointer which nobody else knows the type of.
4466 * sparc-tdep.c, valops.c: Use write_memory rather than
4467 target_write_memory, to get error checking.
4469 * stack.c (locals_info, catch_info, args_info,
4470 get_selected_block, frame_command, up_command): Use
4471 target_has_stack, rather than have_inferior_p or
4474 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
4476 * symfile.h: New file, defining the interface between the
4477 generic and object-file-specific symbol reading code.
4479 * symtab.c: Move generic symbol-reading interface to symtab.c,
4480 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
4481 table to map BFD targets to symbol-reading modules in GDB.
4482 Change index to strchr.
4483 (lookup_struct_elt_type): Use error() rather than hand-made
4484 simulations thereof.
4485 (lookup_partial_symbol): Speedup slightly when length == 0.
4486 (symbol_file_add): New function.
4487 (symbol_file_command): Call it.
4488 (symfile_open, symfile_init): New function.
4489 (add_file_target_command, add_file_addr_command): moved from
4492 * target.c (target_command): use target_kill.
4494 * target.h (target_files_info): Don't declare, never called
4497 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
4498 files to determine stack end address.
4500 * valarith.c (value_x_binop, value_x_unop): Change error message
4501 to be more useful. Pass proper argument to value_struct_elt.
4503 * valops.c (value_assign): FIXME comment that long long
4504 bitfields will break here.
4506 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
4507 Update `make saber_gdb' to work better.
4509 * TODO: A woman's work is never done.
4511 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
4512 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
4513 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
4514 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
4515 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
4516 valops.c, valprint.c, exec.c: Lint.
4519 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
4521 Continuing Intel 960 port merge of GDB.
4523 * Makefile.dist: Merge i960 "nindy-share" files. Rename
4524 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
4525 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
4526 Wack over "make depend" so it handles files in subdirectories
4527 vx-share, nindy-share, bfd, and in the current directory.
4529 * blockframe.c (get_prev_frame_info): Remove fatal error
4530 if stack not defined.
4532 * core.c (core_open, core_detach): New functions that handle
4533 the old "core-file" command as "target core" and "detach" instead.
4534 (core_file_command): Call them.
4535 (core_xfer_memory): Use common routine xfer_memory.
4537 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
4538 dbxread now uses bfd for everything but symbol reading itself.
4539 BFD internals are used to drag out the relevant file offsets.
4540 (partial_symbol_file_open): Change args all around for BFD.
4542 * symtab.c: Rename "value" to "val" everywhere, so we can
4544 (symbol_file_command): New command, moved from dbxread.c
4545 and coffread.c. It uses BFD to read the file, then vectors
4546 based on its type, to dbx or coff symbol readers.
4547 * symtab.h: Extern a few vars for symbol_file_command.
4549 * target.h: Breakpoint takes a char * save area, not a char **.
4551 * valprint.c (val_print): When unpacking bitfields, offset
4552 the address in gdb of the value, if it is declared with a shorter
4553 type. Remove the last "runtime kludge test" of host byte order.
4555 * utils.c: Remove old my_bfd_read routine.
4557 * stack.c (frame_info): Use target_has_stack. Print program counter
4558 register's actual name rather than "pc", since it's called the
4559 "ip" (instruction pointer) on the i960 (sigh).
4561 * target.c (target_command): Add command for selecting a target
4562 type and calling its open routine. This is used for initiating
4563 communication with a particular target, in a generic way.
4565 * tm-i960.h: Update for modern gdb. Remove semicolons from
4566 various macros. Handle reading struct return convention, and
4567 error-out attempts to return structs with the "return" command.
4568 Be sure gdb doesn't think we know how to call functions in the
4571 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
4572 to i960_xxx in lower case.
4573 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
4574 not being defined yet.
4576 * remote.c (remote_open): Call start_remote to initialize
4577 wait_for_inferior during open.
4578 (remote_xfer_inferior_memory): Return length written rather
4581 * remote-vx.c (target_command -> vx_open): Use new generic
4583 * remote-eb.c, inftarg.c, exec.c: ditto.
4585 * infrun.c: Fix comments.
4586 (attach_program -> child_open): Use new generic target command.
4587 (wait_for_inferior): Clear saved register values before target_wait,
4588 so target_wait can set some of them if convenient.
4590 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
4591 Return success indicator, not void.
4592 (child_xfer_memory): Avoid fetching initial word if we'll
4593 overwrite it anyway.
4595 * infcmd.c (attach_command): Use new generic target open routine.
4596 (_initialize_infcmd): Update doc on attach and detach commands.
4597 (do_registers_info): Merge in a byte-order problem as a FIXME
4600 * findvar.c (find_saved_register): Avoid problem in current frame.
4601 (read_relative_register): Ditto.
4602 (write_register): Convert byte order on the way out.
4604 * exec.c (file_command): Add.
4605 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
4606 (xfer_memory): Common function between core_xfer_memory and
4608 (exec_xfer_memory): Use it.
4610 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
4612 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
4613 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
4614 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
4616 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
4618 Merge Intel 960 port of gdb, continuing...
4620 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
4621 symbol_file_command): Pass from_tty arg to hush 'em up.
4623 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
4624 Add magic numbers for 960 COFF format.
4626 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
4628 Merge Intel 960 port of gdb, from Intel "1.2" release.
4630 CHANGE_LOG entries from their port, which was based on
4633 Thu Sep 6 11:02:22 PDT 1990
4634 Remove temp file if download is interrupted.
4636 Wed Aug 1 09:08:33 PDT 1990
4637 Now uses binary protocol to talk to NINDY.
4638 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
4639 Times out after 5 seconds when trying to talk to NINDY.
4641 Tue May 29 12:54:49 PDT 1990
4642 Added variable baud rate (-b switch).
4643 Source code reorganization.
4645 Thu Apr 26 11:09:55 PDT 1990
4646 More cleanup of batch mode; specifically, execute "-s", "-e", and
4647 "-se" switches as soon as they are encountered on the invocation line.
4649 Fri Apr 20 13:47:15 PDT 1990
4652 Thu Apr 19 09:54:28 PDT 1990
4653 Add 'reset' command.
4655 Wed Apr 18 09:48:07 PDT 1990
4656 After opening remote tty, wait for 1 second to go by without input
4657 from it before trying to talk to NINDY (fixes problems with the
4658 Heurikon HK80/V960E).
4660 Mon Apr 4 16:33:05 PDT 1990
4661 Some output was not being suppressed in 'batch' mode.
4663 Thu Mar 22 15:31:11 PST 1990
4664 Ask user if old symbol table should be deleted when new file is
4667 Allow user to run a program downloaded before gdb960 was brought up.
4669 Correct "exec-file" help message for i80960 context.
4671 Correct bug in calculating user space address: could occasionally
4672 corrupt user program.
4674 Make sure to zero low-order bits in rip's because of bug in 960CA
4675 A-step part: could cause operation faults when "next"ing across
4678 Correct bug that made it impossible to get source line numbers for
4679 code loaded at addresses higher than 0x7fffffff.
4681 Wed Jan 10 12:43:22 PST 1990
4682 Open remote tty for exclusive use.
4684 Fri Jan 5 12:14:42 PST 1990
4685 Correct disassembly (CA manual was right after all):
4686 opcode for sysctl is 0x659
4688 Mon Oct 23 12:03:04 PDT 1989
4689 Use G960BASE and G960BIN environment variables to find 'sx' utility.
4691 Mon Oct 16 14:15:09 PDT 1989
4692 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
4694 Mon Oct 2 15:56:31 PDT 1989
4696 Added 960CA disassembly support.
4698 To simplify maintenance:
4699 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
4701 - eliminated opcode.h: incorporates tables into i960-pinsn.c
4702 - moved 960-specific routines from i960-pinsn.c to i960-md.c
4703 - made disassembly interface identical to that in gdmp960.
4707 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
4709 * target.h: Allow targets to stack. Add target_has_memory,
4710 _registers, etc. Restructure memory access and "info files"
4711 to walk the target stack.
4712 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
4713 target.c: Change tables to match target.h.
4714 * inflow.c (child_mourn_inferior): pop child_ops.
4715 (generic_mourn_inferior): Use new has_stack flag.
4716 * infptrace.c (child_xfer_memory): New memory regime.
4717 * inftarg.c (child_files_info): New "info files" regime.
4718 * remote-eb.c: New memory regime, new info files.
4719 * remote-vx.c: New memory regime, new info files. Now use
4720 separate targets for VxWorks attachment to machine, and
4721 actually running a process under VxWorks, since one has
4722 stack & execution & regs and the other doesn't.
4723 * remote.c: New memory regime, new info files.
4724 * sparc-xdep.c (fetch_core-registers): New memory regime.
4725 * target.c: New routines and support for stacked targets,
4726 new memory regime, new info files regime.
4729 Generalize section handling for an arbitrary number of sections,
4730 including use of the new BFD (binary file) library.
4731 * gdbcore.h: Add struct section_table.
4732 * exec.c (build_section_table): Iterate all sections and
4733 record what gdb needs to know about them.
4734 (exec_command): Use it.
4735 (exec_xfer_memory): Use the table.
4736 (exec_files_info): Print the table.
4737 * core.c (core_file_command, core_xfer_memory, core_files_info):
4739 * source.c (find_source_lines): Use bfd_get_mtime.
4740 * dbxread.c: Quick changes to make it compile with new BFD.
4741 * utils.c (error): Avoid using bfd_error in generic routines.
4743 * core.c (core_fetch_registers): Get from the ".regs" section of
4745 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
4747 * inferior.h (attach_flag): Export.
4748 * infcmd.c (run_command): use new target_create_inferior.
4749 * infrun.c (child_create_inferior): Don't return result.
4750 * Makefile.dist (VERSION): 3.91.4.
4752 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
4754 * breakpoint.c (bpstat_num): Handle breakpoints which have
4755 since been deleted, such as temporary breakpoints.
4756 infcmd.c (program_info): ditto.
4758 * core.c (core_file_command): Display the frame where the core
4763 * remote-vx.c (target_command): Merge in target command from
4764 targ-vx.c. A few other cleanups.
4766 * TODO, Projects: Lots more stuff to do...
4768 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
4770 Massive changes to wall off the remote-debugging interface
4771 behind a function vector. The port to handle VxWorks targets
4772 is also part of this.
4774 All files: Replace references to renamed functions,
4775 remove references to remote_debugging, remove references to
4776 have_include_file, have_core_file in favor of target_has_stack,
4777 target_has_memory, etc.
4779 * Modularize the breakpoint interface.
4780 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
4781 a breakpoint instruction.
4782 breakpoint.c: struct breakpoint's shadow_contents now sized as
4784 (insert_breakpoints): Vector to target to install breakpoints.
4785 (remove_breakpoints): Vector to target here too.
4786 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
4787 sparc-tdep.c (single_step): Use new breakpoint interface for
4788 the single-step breakpoints.
4789 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
4790 New file, contains routines to insert and remove breakpoints by
4791 reading out the old contents and later replacing them. This is
4792 how ptrace breakpoints work, and many remote systems as well.
4794 * tm-vxworks68.h: New config file, overrides a few things for
4795 Wind River's preferences.
4797 * target.h: New file, for transfer vector used to talk to the
4798 inferior (child, attached, core, exec, remote, etc). All accesses
4799 to the thing being debugged should come through these vectors.
4800 target.c: New file, routines to handle transfer vector.
4801 (various files): Add transfer vectors XXX_ops for the various
4802 targets and pseudo-targets (core files, etc) we support.
4804 * breakpoint.c (bpstat_stop_status): Further explorations of
4805 watchpoints and why things don't work all the time.
4806 (bpstat_alloc): New fn to allocate a bpstat and chain it.
4808 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
4809 the local gdbinit if it doesn't already have it.
4811 * core.c (core_ops): add and install.
4812 Allow core debugging without exec file.
4814 * dbxread.c (free_and_init_header_files): Merge two fns.
4815 (end_symtab): Free named symbol table when a new version comes in.
4816 (read_dbx_symtab): Relocate all kinds of symbols with base
4817 address. First step toward handling different text, data, bss
4819 (add_file_addr_command): Renamed add_file_command.
4820 (add_file_command): Vector to remote handler.
4821 Add "load" as an alias for "add-file" command.
4823 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
4824 non-returning functions.
4826 * exec.c: Add exec_ops, and push it as a target when an exec
4829 * infcmd.c (run_command): Pass executable file name and arg list
4830 separately when starting an inferior. Permit "run" when no exec
4831 file is specified, for VxWorks.
4832 (detach_command): Move to child_detach in inftarg.c.
4834 * inftarg.c: New file. Unix-child-specific routines, and the
4835 child_ops structure.
4837 * inferior.h (registers): Export "registers" as the way for
4838 target dependent register handlers to find gdb's local copy of
4839 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
4840 since it is now used by places that want wait_for_inferior to
4841 handle the grunge but want to see every trap from the inferior.
4843 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
4844 Eliminate remote_debugging hooks in terminal handling.
4846 * infrun.c: Replace start_inferior with child_create_inferior.
4847 Move all the hair of Unix shells and ptrace idiosyncracies into
4848 child_create_inferior, so remote handlers don't have to deal.
4849 Remove running_in_shell. Rename stop_after_attach to
4850 stop_soon_quietly, and use it in a few other places where we want
4851 to just call wait_for_inferior and get control back on the first
4852 trap. trap_expected now never takes a value > 1.
4853 (init_wait_for_inferior): Initialize static vars when a new
4856 main.c (gdbinit): Add new hook for .gdbinit file name, let
4857 it be overridden by config files as GDBINIT_FILENAME.
4858 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
4859 Both of these are used for VxWorks gdb.
4861 mcheck.c: rename include file "gmalloc.c" to avoid problems
4862 with system include file "malloc.c".
4864 param-no-tm.h: New include file, same as param.h but does not
4865 include the default "tm.h" file. This is used in files where
4866 the target is known, e.g. remote-eb.c or sparc-xdep.c.
4868 param.h: Now just a shell that includes tm.h and param-no-tm.h.
4870 remote-vx.c: New file, VxWorks remote debugging support. Uses
4871 RPC routines that are shared with the target system, in directory
4874 remote.c: Vectorize remote interface.
4876 source.c: Globalize source_path, and make an alias "l" for "list"
4877 since we now have the "load" command.
4879 sparc-xdep.c: Use new param-no-tm.h.
4881 symmisc.c (free_named_symtab): Add new function from Wind River.
4882 However, ifdef it out for now while we think about what it should
4885 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
4887 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
4888 non-Unix-children handle this with their own code in the target
4891 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
4892 source and target lists. Add vx-share to default list of include
4893 directories. Add new files to src and target lists: mem-break,
4894 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
4895 ${srcdir} versions of munch and createtags are used.
4897 * valops.c (find_function_addr): Split out of call_function.
4898 (call_function_by_hand): Rename call_function; this function
4899 calls functions in the target by laboriously patching the target
4900 word-by-word with the right stack, args, regs, etc.
4903 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
4905 Handle AMD 29000 a bit better.
4907 * remote-eb.c (readchar): Mask received char log to make it readable.
4908 (remote_start): Pass arguments down to executing program.
4909 Make startaddr unsigned.
4910 infrun.c (start_inferior): Accept args, pass them to
4912 infcmd.c (run_command): Pass args down to start_inferior.
4914 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
4915 the target object file format.
4916 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
4918 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
4919 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
4921 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
4923 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.

4931 * sparc-tdep.c (do_restore_insn): Simplify.
4932 (sparc_frame_find_saved_regs): Simplify and fix what we find.
4933 (sparc_push_dummy_frame): Simplify and fix what we push.
4934 (sparc_pop_frame): Slightly more hair here, deciding whether
4935 we are restoring a saved PC or returning to a return address in %i7.
4936 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
4938 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
4939 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
4940 * obstack.h (chunkfun): ditto.
4941 * defs.h (xmalloc, xrealloc): ditto
4943 * utils.c (quit): Grab the terminal from the child if necessary.
4945 * inflow.c (term_status_command): Rename to term_info, change
4948 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
4949 (is_delayed_branch): Speed up.
4950 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
4951 Still missing some float ops, and needs testing.
4953 * Support for input and output radixes other than base 10
4954 * defs.h (input_radix, output_radix): Declare.
4955 * expread.y (yyparse, parse_number): Handle changes of input
4956 radix, and ambiguous names-or-numbers in radixes >10.
4957 * printcmd.c (print_scalar_formatted): Print formatted hex
4958 numbers in varying column widths.
4959 * valprint.c (val_print): Use output_format to print scalar ints.

4961 (set_output_radix): Set output_format from output_radix.
4962 (_initialize_valprint): add `set radix' but leave the others off.
4964 * main.c (execute_command): Let stupid questions be turned off.
4965 (_initialize_main): Handle "set stupidity", etc.
4967 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
4968 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
4970 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
4972 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
4973 bfd stuff is still screwed up, but with some manual work, it
4976 * breakpoint.c (bpstat_do_actions): Start over if a command
4977 proceeds the inferior, since the inferior will have stopped and
4978 will need to have its new stop-actions taken care of.
4980 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
4981 compiler fits, simplify it.
4983 * gdb.texinfo (directory command): Doc new dir command.
4984 source.c (directory_command): "dir" now puts things on the front
4985 of the path, moves dups up front, and handles multiple names
4986 on the command line, inserting each one in order. It also
4987 blows away cached line and full_filename info.
4989 * stack.c (backtrace_command): Skip "more stack frames follow"
4992 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
4993 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
4994 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
4995 The only odd one was Gould NP1, which had defined vprintf to
4998 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
4999 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
5000 variable, inspect_it.
5001 valprint.c (print_string, val_print): Use the global inspect_it
5002 to indicate whether to print in Epoch style or normal style.
5004 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
5006 * printcmd.c (call_command): add an alias for the "print" command
5007 which runs expressions and doesn't print the result if void.
5008 (print_command_1): implement it.
5010 * command.c: Remove #if 0'd code. Initialize all the fields
5011 in add_cmd (). Rename do_nothing_command to
5012 not_just_help_class_command, and make it externally visible.
5013 command.h: add user_commands to struct.
5014 * main.c (define_command): Don't overload c->function with a char
5015 string as well as a function pointer.
5017 * eval.c (evaluate_subexp): Reinstall tiemann changes to
5018 calling convention of value_struct_elt () that got dropped in
5021 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
5022 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
5024 * tm-sparc.h (POP_FRAME): replace some constants with defines.
5026 * sparc-xdep.c (store_inferior_registers): defer stores to regs
5027 until a good time (e.g. when we are about to run the child),
5028 saving ptrace calls.
5029 * infrun.c (proceed): handle DO_DEFERRED_STORES.
5030 * tm-sparc.h: define DO_DEFERRED_STORES.
5032 * sparc-xdep.c (store_inferior_registers): when storing float
5033 registers, don't store stack regs too. When storing the SP,
5034 however, DO store the stack regs too. This fixes a bug in which
5035 the dummy frame is not recognized when a call_function finishes,
5036 because its frame pointer (in the stack regs) was never
5038 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
5039 even though we don't know how to read them from an inferior.
5040 valops.c (call_function): Comment about storing SP.
5042 * infrun.c (save_inferior_status): Save away the original bpstat
5043 chain so it can be restored later. Install the copied version for
5044 use by whoever saved the status. It will be blow away by
5045 restore_inferior_status, and the original chain restored. This is
5046 important for people who have pointers into the original.
5048 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
5049 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
5050 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
5053 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
5055 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
5056 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
5057 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
5059 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
5061 * Merge Mike Tiemann's multiple inheritance changes from Sun.
5062 Store the baseclasses in a type struct starting from array element
5063 0 rather than from the unusual array element 1.
5065 dbxread.c: the above.
5066 (virtual_context): Add
5067 Read new debug information about which virtual function table
5068 a virtual function is from, and store it in fn_field.fcontext.
5070 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
5071 TYPE_FN_FIELD_STATIC_P.
5073 symtab.c: the above.
5074 valops.c: the above. Handle pointer casts of object *'s.
5075 (search_struct_method): Add.
5076 (value_struct_elt): First arg is now a pointer to a value, and is
5079 valprint.c: the above.
5080 values.c (value_virtual_fn_field): Add type arg. Handle
5081 offsetting to the proper object when calling virtual fns.
5083 (baseclass_addr): Add valuep arg.
5085 * README: Document the current state of BFD config (missing).
5086 * TODO, ChangeLog, Makefile.dist: Roll version.
5087 * WHATS.NEW: Add summary of changes since 3.5.
5089 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
5091 * dbxread.c (read_struct_type): Clear bit vectors whenever
5093 symtab.c (B_CLRALL): define.
5095 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
5096 using == rather than =. Huh... This fixes the dreaded problem
5097 wherein builtin_type_int becomes TYPE_CODE_FLT.
5099 * core.c (info_files): Show the inferior pid.
5101 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
5102 already knows how to look in the source directory.
5104 * Remove psymtab hair from many places. Remove duplicated code
5105 for searching symbol tables. Hide psymtabs from most places.
5106 Make it fast to get from a psymtab to its symtab.
5108 blockframe.c (blockvector_for_pc): Remove psymtab hair.
5109 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5110 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5111 dbxread.c: export psymtab_to_symtab, make it work if called N times.
5112 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
5113 new symtab completely. New psymtabs get symtab pointer
5114 initialized to zero. Remove MI warning printf.
5115 symtab.h: Comments. Add psymtab to symtab pointer.
5116 (PSYMTAB_TO_SYMTAB): New macro.
5117 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
5118 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
5120 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
5122 (print_frame_info): Avoid special-casing symbols that have not yet
5125 * source.c (open_source_file): Quick path if we have already
5126 located the source file by its full name.
5128 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
5129 find_pc_psymtab. When a name is found in the misc function
5130 vector, search the symbol table for its mangled name, not the
5131 name that the user typed.
5133 * bfd.h: Fix missing comment terminators, make #endifs match.
5135 * valarith.c (value_less): Handle unsigned int comparisons.
5136 Add FIXME about pointer compares, which assume host and target
5137 pointers are the same.
5139 * command.c (do_nothing_command): lint
5140 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
5141 fix comments on debug symbol format for visibility. Actually set
5142 visibility of symbols.
5143 main.c (echo_command): lint; use <readline/history.h>.
5144 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
5145 obstack.h (_obstack_blank): Rearrange pointer math to avoid
5146 pointing past end of allocated memory; saber complains.
5147 obstack.h: Declare the external functions that we use.
5148 valarith.h: use <string.h>
5149 solib.c (solib_add): lint.
5151 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
5153 * main.c (initialize_main): Default info_verbose to off, now that
5154 symbol reading is fast.
5155 (quit_command): Avoid clobbering exec_bfd while quitting.
5157 * Initial BFD (binary file diddling library) merger:
5158 coffread.c: Change AOUTHDR to struct exe_hdr.
5160 core.c: initialize initialized data at compile time.
5161 (core_file_command): Move from coredep.c, convert to bfd.
5162 (xfer_core_file): Convert to bfd.
5163 exec.c (exec_file_command): use bfd routines.
5165 mips-tdep.c: Remove exec_file_command and friends.
5168 * coredep.c: (fetch_core_registers) Convert core_file_command to
5169 fetch_core_registers.
5170 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
5172 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
5173 (my_bfd_read): More bogosity, which I don't think we call.
5174 (program_name): Remove this atrocity asap!
5176 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
5179 values.c: allocate_repeat_value was not clearing the
5180 optimized_out field.
5181 (value_static_field): minor stylistic fix (wrong macro was used).
5182 valops.c (value_struct_elt_for_address): didn't work for C++
5185 * signame.c (_initialize_signame): Initialize signal names once.
5187 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
5188 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
5189 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
5191 * remote-eb.c: Support user-settable baud rates on the serial port.
5193 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
5195 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
5197 * tconfig/sun3os4: Remove warning about native assembler,
5198 since it also occurs in the xconfig file.
5200 * findvar.c (registers): Allocate some slop after `registers'
5201 to prevent stray accesses from trashing the next variable.
5203 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
5204 on the sun-3, by changing the #ifdef from `sun3' (which is not
5205 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
5206 vars, which happened to follow `registers' in the executable.
5208 * readline/history.c (history_search): Heed gcc-2's advice
5209 and parenthesize && inside ||).
5211 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
5212 tm-29k.c: Insert FSF copyright headers.
5214 * remote-eb.c: Better comments.
5216 * Makefile.dist: Update to 3.91.6.
5217 * TODO: note PREPARE_TO_STORE problem.
5219 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
5221 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
5223 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
5225 * infrun.c (wait_for_inferior, at end): Don't set up
5226 prev_* if the inferior no longer exists.
5228 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
5229 CANNOT_EXECUTE_STACK.
5230 valops.c (call_function): Use it.
5232 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
5234 * inferior.h (PC_IN_CALL_DUMMY): New macro.
5235 infrun.c (wait_for_inferior, 2 places): Use it.
5237 * values.c (value_being_returned): Only use
5238 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
5240 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
5241 right thing for remote-eb.c.
5243 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
5244 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
5246 * blockframe.c: Put get_frame_saved_regs inside #if !defined
5247 (FRAME_FIND_SAVED_REGS).
5249 * findvar.c ({fetch,store}_registers): Check for
5250 REMOTE_{FETCH_STORE}_REGISTER macro.
5252 * findvar.c (get_saved_register): Add argument lval and
5253 change meaning of argument addr.
5254 findvar.c: Change calls to get_saved_register to reflect
5255 new calling convention.
5256 valops.c (value_assign): Use get_saved_register instead of
5257 find_saved_register.
5259 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5261 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
5262 an (uninitialized) pointer to one. Use "&" when passing it
5265 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5267 * coffread.c (getfilename): Use DGUX x_offset and x_name if
5270 * coffread.c (symbol_file_command): Put semicolon after
5272 Put safe_to_init_tdesc_context in #if defined (TDESC).
5273 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
5274 coffread.c: #include <sys/stat.h>.
5275 (read_coff_symtab): Typo: in_source_files -> in_source_file.
5276 Add missing ')' in check for "lc%" and friends. Remove
5278 Declare read_one_sym() at top of file.
5279 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
5280 MC68WRMAGIC can have the same value without causing a duplicate
5283 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
5285 * Allow a Makefile to be built without building the
5286 tm and xm file links that screw up builds in subdirectories.
5287 This is done with `config.gdb none', then you can do things
5288 like `make gdb.tar.Z'.
5289 * tconfig/none: Config file for no target system
5290 * xconfig/none: Config file for no host system
5291 * config.gdb: If no TM or XM files are called out by the
5292 host or target file, don't make links for them.
5294 * cplus-dem.c: Add documentation.
5296 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
5297 simple error, so the user's gdb doesn't crash due to some object
5298 file problem (e.g. somebody is rebuilding the file out from under
5301 * printcmd.c (print_address_symbolic): demangle the symbol.
5303 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
5304 Motorola copyrights in it. Make "make gdb.tar.Z" work.
5305 (alldeps.mak): sort and uniq all results from this; duplicates
5306 hose gdb.tar.Z link building. Remove RCS files from
5307 tconfig and xconfig. Add config files for sun386. Add
5308 a few odd files to OTHERS and HFILES.
5310 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
5312 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
5313 Roll version number to 3.91.5. Make lint work in bindir.
5315 * README: Document cross-debugging and new file structure.
5317 * blockframe.c: Lint. Include "value.h" to declare read_register.
5318 (find_pc_partial_function): remove duplicate line.
5320 * command.h: Lint. Declare error_no_arg and dont_repeat.
5322 * tm-news.h: Remove inadvertently duplicated stuff.
5324 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
5325 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
5327 * config.gdb: Allow `config.gdb host target' form. Clean
5328 up previous change that printed bogus messages when you just said
5331 * core.c: #include "command.h" for lint.
5334 * main.c: Remove some casts of enums. Lint.
5341 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
5343 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
5344 read it from memory. This will allow us to save ptrace calls
5345 eventually. Changed caller single_step too.
5347 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
5348 that we aren't going to use, saving many ptrace calls, especially
5349 when watchpointing or single stepping. Use some #define's for
5351 (store_inferior_registers): Ditto.
5352 (core_file_command): Use some #define's for constants.
5354 * tm-sparc.h: Add #define's for some register numbers, so we
5355 can eliminate the use of random constants in sparc-xdep.c.
5357 * stack.c (frame_command, print_frame_info, up_command,
5358 down_command) Remove frame_changed, since it
5359 causes a bug and doesn't seem to do anything useful. In some
5360 places it was used as a flag, in others as a stack level (?).
5362 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
5363 default is to use the portable (vprintf) version rather than the
5365 * xm-news.h (MISSING_VPRINTF): Add.
5367 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
5369 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
5371 * Remove stuff that forces -Bstatic linking of gdb, and warnings
5372 about linking debugged programs -Bstatic in the sun?os4 config
5373 files in tconfig and xconfig subdirectories.
5375 * main.c (main): Remove unreached exit(0) now that we exit
5378 * Create TODO file for online bug list. There are too many
5379 "little" bugs to keep track of on paper.
5381 * Change Projects file to refer to bug-gdb@cygnus.com
5382 rather than kingdon@ai.
5384 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
5386 * Makefile.dist (VERSION): 3.91.4 now.
5388 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
5389 (condense_misc_bunches): Add sanity check that misc_count is
5390 the same as the number of symbols in the bunch.
5392 * coffread.c: rename init_misc_bunches. Pass an argument
5393 to condense_misc_bunches (a zero).
5395 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
5396 every time we are called; don't rely on our caller to do it.
5397 (add_file): Remove call to init_misc_bunches.
5399 * mipsread.c: Only warn, don't error, if unknown symbol types.
5400 This keeps an old gdb from falling on its face if it sees newly
5401 extended symbol info. Rename init_misc_bunches.
5403 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
5405 * Merge in changes from Per Bothner for DECstations and other
5406 MIPS stuff. The rest is Bothner speaking:
5408 The next message is a merger of Alessando Forin's mips port with
5409 mine. I've tried to use my good if biased judgment to get
5410 the best of both. It *does* need testing.
5412 Some of the changes are general, *not* mips-specific.
5415 Didn't believe in little-endian bit order.
5416 There are still inconsistencies about whether flags
5417 like BITS_BIG_ENDIAN are integer (#if ...) or
5418 boolean (#ifdef ...). I tried to paper over them.
5420 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
5421 Moved some misc_function code that was common to
5422 {dbx,coff,mips}read.c to symtab.c.
5423 In the process, I think I cleaned things up a bit.
5424 At the same time, moved obsavestring and obconcat to symtab.c.
5427 Removed obsolete condense_addl_misc_bunches (use
5428 condense_misc_bunches(1) instead).
5431 Needed to include <sys/dir>, at least on DECstations.
5433 valops.c, mips-tdep.c, tm-mips.h:
5434 Added PUSH_ARGUMENTS macro to support funny argument-pushing
5435 conventions (when STACK_ALIGN is insufficient).
5436 Needed on mips, where doubles need 8-byte alignment,
5437 but ints only need 4.
5440 Removed cruft that was not being used.
5441 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
5444 Print $ before register-names (I think that makes things a little
5446 Never print two instructions, even if one delays.
5447 Removed hex-disassemble set_cmd. (This is not mips-specific,
5448 so I think the argument is whether it is generally worthwhile or not.
5449 I'm inclined to think not, given how easy it is to
5450 convert between radixes in gdb.)
5453 This is basically Alessando's code.
5454 It doesn't use obstacks; I changed it to use obstacks
5455 in a few minor places where using malloc causes a
5456 memory leak. (Probably, more places could/should be changed.)
5457 I added record_misc_function where it was missing.
5458 In symbol_file_command and add_file_command, I tried
5459 to make the code consistent with more recent versions.
5460 Minor sylistic changes in parse_procedure.
5461 Make a .gdbinfo. psuedo-symbol point back to the real
5462 procedure symbol (using the isym field).
5465 This is basically from my port, but with a lot of details
5466 and a number of routines merged in from Alessando's version.
5467 I basically used my code "raw" backtrace (use heuristics
5468 from the actual code, rather than symbol table info) - though
5469 the idea is Alessandro's. I feel my code is a little cleaner
5470 here, particularly in being a little more flexible, such as being
5471 able to handle gcc-produced code (which it now can).
5472 It also doesn't do frame caching (which is not useful
5473 more recent gdb versions).
5474 I also used my code for push_/pop_dummy, more or less.
5475 I tried to incorporate AF's code for testing sigtramp
5476 while backtracing; I probably got it wrong.
5477 Added mips_print_register, which tries to scrunch as much
5478 information as possible on a screen...
5479 Removed the skip-prologue set_cmd. As with hex-disassemble (see
5480 under mips-pinsn.c), I don't see anything mips-specific here,
5481 and I don't see it being all that useful anyway.
5484 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
5485 Use more register names (rather than hard-cases numbers).
5487 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
5489 * Hack up 3.90.11 changes:
5491 * Makefile.dist (depend): parameterize $(GCC).
5492 Add solib.c and solib.o.
5493 (readline): Fix vpath for both absolute or relative SRCDIR.
5495 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
5496 Also, let the part I didn't understand at least compile so
5497 I can test the rest. FIXME.
5499 * dbxread.c: Fix thinko using strcmp.
5500 (init_psymbol_list): declare static.
5501 (partial_symbol_file_open): Comment cleanups better, avoid
5502 cleaning up the string table since the caller will do that.
5503 Move the stat for mod time into symbol_file_command, temporarily.
5504 (There should be a mod time for each symbol file, eventually,
5505 to control its rereading. FIXME.)
5507 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
5508 SunOS, which gives error for shared libs otherwise. (From
5509 Schaefer, probably FIXME needs work for portability.)
5511 * solib.c: Move #include "param.h" to work.
5512 Lowercase all the Uppercase Letters In the Messages.
5513 (find_solib): Clean up inferior_so_name for debug printouts.
5514 Allow no argument, to mean all shared libraries.
5516 * symmisc.c: include param.h to get CLEAR_SOLIB.
5518 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
5520 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
5521 to 3.90.11. ChangeLog entries below are from this.
5523 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5527 * Makefile.dist (HFILES): Add tm-sunos.h.
5529 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5533 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
5535 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
5537 * sparc-opcode.h Added single-operand version of rett.
5539 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5541 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
5542 Put parens around gcc_p in expansion.
5544 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5546 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
5548 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5550 * Changes for Sun shared libraries:
5551 blockframe.c (find_pc_partial_function): If a non-text symbol
5552 is found, set *address = pc - FUNCTION_START_OFFSET.
5553 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
5554 Disable breakpoints instead of giving an error.
5555 source.c (select_source_symtab): Initialize cs_pst.
5556 symmisc.c: Call CLEAR_SOLIB if defined.
5557 symtab.h: Make text{low,high} CORE_ADDR not int.
5558 (psymtab): New field addr.
5560 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
5561 (record_misc_function): Give correct type for N_DATA symbols.
5562 (condense_misc_bunches): do "misc_function_count = j" regardless
5564 Take code which is shared between symbol_file_command and
5565 add_file_command and put it into partial_symbol_file_{open,read}.
5566 Split add_file_command into add_file_command and add_file.
5567 Make psymtab_to_symtab read in the string table if the file
5569 Two new parameters to read_dbx_symtab and start_psymtab.
5570 tm-sunos.h: New file.
5572 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5574 * infcmd.c: Change cont_command to continue_command and "cont"
5577 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5579 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
5581 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
5583 * values.c (USE_STRUCT_CONVENTION): Check for structures of
5584 size 1,2,4,8 rather than size < 8.
5586 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
5587 as necessary, not just once.
5589 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
5591 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5593 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
5595 * tm-news.h: Add CALL_DUMMY_*.
5597 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
5599 * config.gdb: In list_host, list_target, use ${i}, not $i.
5601 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5603 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
5605 * sparc-opcode.h: Change all store floating-point state register
5606 instructions to have the right match & lose fields.
5608 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5610 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
5612 config.gdb: If srcdir != ., create readline directory and
5613 copy a makefile into it.
5615 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
5616 consistency with POSIX.
5618 * breakpoint.c (bpstat_stop_status): Disable watchpoint
5619 when we exit its exp_valid_block.
5621 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
5623 * Makefile.dist: Bump version to 3.91.3.
5625 * Clean up handling of breakpoint commands (somewhat).
5626 Prompted by Tiemann bug report "cont 10" doesn't work any more.
5628 inferior.h: Add breakpoint_proceeded to inferior status struct
5629 and globals; save it and restore it.
5630 (clear_breakpoint_commands): Cleanup, remove old #define.
5632 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
5633 (save_inferior_status, restore_inferior_status): handle it also.
5634 (proceed): Remove earlier code that set breakpoint_proceeded.
5635 It is now set only in clear_proceed_status.
5636 (clear_proceed_status): Cleanup, use bpstat_clear rather
5637 than clear_breakpoint_commands. No callers need the stop_bpstat
5638 between clear_proceed_status and proceed.
5640 infcmd.c: Add breakpoint_proceeded definition and comment.
5641 (cont_command, jump_command, signal_command): Move call to
5642 clear_proceed_status right next to call to proceed.
5644 breakpoint.c (bpstat_do_actions): Avoid clobbering our
5645 caller's argument while running down the chain of breakpoints.
5646 Use new variable "breakpoint_proceeded" to determine when
5647 a command that it executes moves the inferior past the
5649 (bpstat_clear): Handle NULL argument.
5650 (bpstat_clear_actions): Avoid useless call to
5651 breakpoint_auto_delete.
5652 (delete_breakpoint): Clean up bpstat's that are pointing to
5653 the deleted breakpoint from the stop_bpstat chain.
5654 (breakpoint_auto_delete): Simplify.
5656 * Clean up handling of EOF, error on stdin, etc. This was
5657 prompted by a network problem that caused gdb to go into an
5658 infinite loop filling up its malloc'd memory.
5660 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
5661 not clear_breakpoints_commands, which is now gone.
5662 (main): If command_loop returns (e.g. from EOF on stdin), do
5663 a quit_command (looping back to command_loop if quit_command
5664 doesn't really quit).
5665 (command_loop): check result from command_line_input and
5666 exit if it returns NULL, rather than passing the NULL to
5668 (gdb_readline): Free malloc'd result space before returning
5671 * utils.c (query): Handle C-d to mean "yes", just as if the
5672 input was not a terminal. Also avoid infinite loop if EOF
5673 occurs in mid-input-line before newline. This allows
5674 query to be used at EOF on stdin with reasonable results.
5676 * infrun.c (proceed): Set breakpoint_proceeded.
5678 * values.c (value_as_long): Avoid infinite recursion for enums.
5679 (_initialize_values): Fix typo in help msg (kingdon).
5681 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
5682 RL_LIB for linking. This allows -lreadline for linking
5683 and nothing for dependencies, once readline is a real library.
5685 * config.gdb: Jim Kingdon: give useful error message if the
5686 host or target type is not recognized.
5688 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
5689 it just defines it. Dumb, but deal with it.
5691 * Jim Kingdon suggests:
5692 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
5694 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
5696 * Makefile.dist (VERSION): Bump version # to 3.91.2.
5698 * Clean up Bothner's changes.
5700 * blockframe.c (clear_pc_function_cache): New function.
5701 * blockframe.c: remake cache_pc_function_* static.
5702 * dbxread.c (symbol_file_command): remove references to
5703 cache_pc_function_* variables.
5704 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
5705 * printcmd.c: Avoid kludging a global variable (addressprint)
5706 to avoid printing the address of a string twice. Instead,
5707 pass the format letter 's' down low enough that it can be seen
5708 to avoid this problem.
5709 (print_formatted): Pass format arg to value_print.
5710 (restore_addressprint): Remove function.
5711 (do_examine): Avoid hacking addressprint, cleanups and such.
5712 (print_frame_args): Add a comment to a Bothner change.
5713 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
5714 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
5715 to wipe out the values cached in blockframe.c.
5716 * symtab.c (find_method): Add comment saying how big you must
5717 allocate to be "big enough". Per being terse again.
5718 * valprint.c (val_print): Handle format letter "s" to print
5719 strings without addresses. Add comment to vtbl printing code
5720 which casts with wild abandon. Rearrange reference-printing
5722 @0xaddr: value (print w/addressprint)
5723 value (print w/~addressprint)
5724 @0xaddr (parameter lists w/addressprint)
5725 or nothing (parameter lists w/o addressprint)
5727 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
5729 * Merge more changes from Per Bothner:
5731 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
5732 annoying) that I tried to improve it. Here are my suggestions.
5734 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
5737 Do automatic de-reference when taking the address of a reference.
5739 Don't deref_ref when printing parameter lists.
5741 More attempts at treating refernences properly.
5743 In val_print, if deref_ref==0, don't print dangling " = ".
5745 Add COERCE_REF macro, which de-references an REF.
5747 * Merge changes from Per Bothner:
5749 * Fixed (Sony news)-specific configuration problems.
5750 * Fixed other problems with using vanilla pcc and libc (enum problems;
5751 assumption that vsprintf exists).
5752 * Some major speed-ups (finc_pc_partial_function now caches a match;
5753 parsing avoids duplicate symbol_lookup calls).
5754 * Changed handling of baseclasses (no longer use baseclasses field
5755 of struct type, use the first n_baseclasses fields instead).
5756 * Various minor changes/fixes, most C++-related.
5759 Cache the most previous match from find_pc_partial_function.
5760 (Save both low and high ends of matching function's pc range.)
5761 This speeds up the loop of infrun.c:wait_for_inferior quite
5762 a bit, and makes step/next commands much zippier.
5764 Added an enum->int cast (otherwise, some compilers barf).
5766 No longer set baseclass offset to 0, since multiple
5767 inheritance now mostly works.
5768 Added a number of casts, to shut up compiler warnings
5769 (after stabs where made enums, not ints).
5770 When discarding a symbol table (in symbol_file_command),
5771 must clear the cache introduced in blockframe.c.
5772 Don't convert $vtbl_ptr_type to vtbl any more.
5773 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
5774 Mask off sign bit emitted by g++ for virtual table offset.
5775 Set voffset to -1 (not 1) for static member functions.
5777 Changed parsing/lexing of names to avoid doing symbol lookup twice
5778 (once when lexing to determine symbol class, once for real).
5779 Now only call symbol_lookup once. Fields of 'this' win especially big.
5781 Subpress printing addr twice in the case of 'x/s addr'.
5783 lookup_basetype_type is no longer used.
5784 Add find_methods as recursive helper function to decode_line_1.
5785 This allows multiple inheritance to work.
5786 Also, once one or more matches has been found, do not look in
5787 base-classes. (Baseclass methods would be overridden, anyway.)
5789 Removed baseclasses array in struct type.
5790 Instead of using baseclasses[i], use fields[i-1].
5791 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
5792 Changed sign convention of voffset (previous was inconsistent).
5794 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
5796 Used to assume existence of vsprintf. Re-written to not need it
5797 if HAVE_VPRINTF is undefined.
5799 typecmp was too pessimistic. Made it less so.
5801 Don't print space after address.
5802 If vtable points to a misc symbol (with 0 offset), print it,
5803 since that indicates the actual class of the object.
5804 Changed ype_print_derivation_info to use new inheritance
5805 scheme (without baseclasses vector).
5807 In value_primitive_field, fixed some bugs left over from previous set of fixes.
5808 Also, changes needed because TYPE_BASECLASSES were removed.
5810 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
5812 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
5815 If there is no path set, and the symbols don't indicate what directory
5816 a file was compiled in, look in the current directory. But either
5817 a path or a known compilation directory will prevent this.
5820 Three independent bug fixes:
5821 * Remove the #if 0 block that breaks some stuff.
5822 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
5823 adapt gdb to either SunOS 4.0.* or 4.1.
5824 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
5827 Instantiate the class T when looking for methods in it. (Tiemann@sun)
5830 (type_print) Demangle the name being printed.
5831 (type_print_base) Handle botched demangling without coredump (tiemann).
5834 (check_stub_method): Document routine.
5835 (tiemann) fix bug for no-arg functions
5836 Avoid clobbering beyond end of malloc'd storage.
5837 Terminate the argument list properly.
5839 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
5841 * Changes merged by John Gilmore:
5844 In breakpoint_1, use new print_address_symbolic instead
5845 of find_pc_partial_function. (This forces use of assembler-level
5846 addresses, and avoids misleading non-mangled source-level names.)
5848 Generalize ansi argument such that -1 means skip arglist totally.
5849 Removed global variable print_ansi_qualifiers (which made
5850 code non-reentrant), in favor of extra explicit arguments
5851 to internal routines.
5853 Add new helper function print_address_symbolic.
5854 Use find_pc_misc_function instead of find_pc_partial_function
5855 (since we want assembler-level symbols here).
5857 Print unknown function as just "f (...)", not "f (...) (...)".
5858 Use new fputs_demangled explicitly.
5860 Fixed a typing violation (problem: value.h cannot be imported
5861 without renaming many variable in this file).
5862 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
5863 decode_line_1: Moved forward some never-reached code.
5864 Made decode_line_2 skip function prologues correctly.
5866 fputs_filtered should not demangle by default.
5867 Add new fputs_demangled to demangle on demand..
5869 Change value_struct_elt to use value_primitive_field (using recursive
5870 utility function search_struct_field). This allows foo.bar to work
5871 for multiple inheritance (so far only for data fields).
5872 Change check_field in the same way (recursive helper function
5873 to support multiple inheritance).
5874 (Note: there are more of these problems that I haven't fixed.
5875 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
5876 value_of_this: 'this' symbol name is now just "this", note "$this".
5878 Don't print static members.
5879 Avoid printing "members of <type>" if there are none.
5880 Simplified type_print_derivation_info by merging duplicate code.
5881 Remove useless blank lines in type_print_base (ptype command).
5883 Added declaration of new routine value_primitive_field.
5885 Added value_primitive_field which is generalized version of
5886 value_field that can handle multiple inheritance (non-zero offsets etc).
5887 Re-implemented value_field to call value_primitive_field.
5889 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
5891 * infcmd.c -- insert else to avoid 'delete env' coredump when you
5892 delete the whole environment. Karl Berry reported the bug.
5893 * source.c - fix openp to avoid //'s in filenames, which
5894 trigger an Emacs bug causing it to not be able to find files
5895 when running gdb in a window.
5896 * dbxread.c - zap the #if 0 that botches the add-file code.
5897 It seems to work a lot better without all the code commented out.
5899 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
5901 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
5904 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
5906 * Makefile - added a ${CFLAGS} to a couple of entries,
5907 added remote-sa.sparc.c
5908 * added remote.sa-sparc.c, a modification of remote.c
5909 which conducts a dialog directly with the SparcStation prom.
5910 * breakpoint.c, infrun.c, sparcdep.c added
5911 remote_insert_breakpoint(), and remote_remove_breakpoint()
5912 to breakpoint.c instead of directly writing breakpoint instructions.
5913 * sparcdep.c on remote_debugging,there is no need
5914 to remove signle step breakpoint instructions.
5915 * main.c added "-epoch" flag and "int epoch_interface" to main.c
5917 * printcmd.c - epoch interface sends lisp expressions to open up
5918 epoch windows on inspection.
5919 * valprint.c - added arrayprint, and addressprint and made adding
5920 format controls easier
5921 * wait.h added a couple of undef's because we were getting
5922 complaints about WSTOPSIG and WTERMSIG begin redefined.
