1 Sun Oct 27 18:18:39 1991 Stu Grossman (grossman at cygnus.com)
3 * main.c (initialize_history): Read history after reading all
6 Sun Oct 27 14:09:25 1991 John Gilmore (gnu at cygnus.com)
8 * buildsym.c: Break out initial malloc sizes.
9 (record_line): Record directly in a subfile. Alloc on demand.
10 (compare_line_numbers): Add from xcoffread.c.
11 (end_symtab): New params say whether to sort pendings and
12 linetable. Patch block stabs if defined. Shrink linetable before
13 allocating the symtab.
14 * buildsym.h: Delete line_vector* and prev_line_number. Add
15 global_stabs and file_stabs for xcoffread.
16 * dbxread.c (start_subfile): Move to buildsym. Change above calls.
17 * symtab.h: LINETABLE(symtab) can now be null. Zap LINELIST.
18 * symmisc.c, symtab.c: Cope with null LINETABLEs.
20 * blockframe.c: Pass fromleaf to INIT_EXTRA_FRAME_INFO.
21 * tm-29k.h, tm-88k.h, tm-i960.h, tm-irix3.h, tm-mips.h, tm-pyr.h,
22 tm-sparc.h: Accept fromleaf parameter.
23 * c-exp.y (yyerror): Pass error message if given.
24 * configure.in: Add rs6000 host and target.
25 * inflow.c (new_tty): O_NOCTTY kludge for RS/6000.
26 * symfile.h (entry_point): Add.
28 Sat Oct 26 00:16:32 1991 John Gilmore (gnu at cygus.com)
30 * buildsym.c: New file. Breaks out symbol-table-building routines
31 from dbxread.c, so they can be shared with xcoffread.c.
32 * buildsym.h: New file. Declarations for buildsym.c users.
33 * dbxread.c: Remove large chunks into buildsym.c.
34 * Makefile.in: Add buildsym.c and buildsym.h.
36 * symfile.c (syms_from_bfd): New routine.
37 (add_symbol_file): Call it to do the real work.
38 (syms_from_bfd): Initialize entry_point before calling symfile_init.
39 * symtab.h, symfile.c, coffread.c, mipsread.c, dwarfread.c:
40 Avoid declaring or setting entry_point (symfile.h & symfile.c cope).
42 Fri Oct 25 18:59:32 1991 Per Bothner (bothner at cygnus.com)
44 Various fixes to improve g++ debugging.
45 * symtab.h: Add is_const and is_volatile flags for each method.
46 These are bit fields - take their space from voffset,
47 which shrinks to 30 bits. Since voffset is now a bitfield,
48 make it unsigned for portability. This changes its interpretation
49 slightly: Static methods now have voffset 1 instead of -1,
50 and virtual offsets start at 2, not 1.
51 * symtab.c: Renamed gdb_mangle_typename to gdb_mangle_name,
52 since it now returns an entire magled method name, not just
53 the type part. This avoids some duplication.
54 It also allows us to correctly mangle const and volatile
55 methods (using the new is_const and is_volatile bit fields
57 * valprint.c (type_print_base), values.c (check_stub_method):
58 Simplify by using new gdb_mangle_name.
59 * values.c (value_headof): Fix to correctly handle single
60 inheritance (actually two fixes, either of which suffices).
61 * dbxread.c (read_struct_type): Handle const and volatile
63 * dbxread.c (read_struct_type): Yet one more place where
64 we must handle '\\' continuations.
65 * valprint.c (vtbl_ptr_name): Add final '\0'.
67 Fri Oct 25 16:06:38 1991 Stu Grossman (grossman at cygnus.com)
69 * tm-sparc.h, tm-68k.h (EXTRACT_RETURN_VALUE): fix output of
70 short return values for sparc and 68k. Patch from Paul Eggert.
72 * coffread.c, coredep.c, i386-xdep.c: install patches for
73 SysV/386 3.2 from Mauro DePalma.
75 Fri Oct 25 02:02:13 1991 John Gilmore (gnu at cygnus.com)
77 * core.c (core_file_info), exec.c (exec_file_info): Print file
78 type. Use printf_filtered.
80 * valops.c (value_fetch_lazy): Avoid 0-length fetches.
82 Thu Oct 24 23:06:40 1991 Fred Fish (fnf at cygnus.com)
84 * dwarfread.c: Add casts to remove compiler warnings.
86 * tm-3b1.h, tm-68k.h, tm-altos.h, tm-amix.h, tm-hp300bsd.h,
87 tm-hp300hpux.h, tm-isi.h, tm-news.h, tm-pn.h, tm-sun2.h,
88 tm-sun3.h: Remove locally duplicated code for calling functions
89 in the inferior. The only differences were in the specific trap
90 vectors used and whether or not an fpu was present. These are
91 now handled by appropriate definitions of BPT_VECTOR and
92 HAVE_68881 respectively. Other minor obvious cleanups.
94 * valops.c: Correct a minor misspelling.
96 * utils.c: Remove local BSD/USG hacks that are now in libiberty.
98 * dwarfread.c: Remove prototype for dwarfwarn. Does not work
101 Thu Oct 24 09:33:44 1991 John Gilmore (gnu at cygnus.com)
103 * stack.c (frame_command): Always print. Use new
104 frame_select_command to select a frame without printing.
106 * dwarfread.c: Use <varargs.h>, since <stdarg.h> is not portable.
108 Thu Oct 24 01:32:51 1991 Fred Fish (fnf at cygnus.com)
110 * dwarfread.c: New file for DWARF debugging format support.
112 * elfread.c: New file for ELF object file format support.
114 * procfs.c: New file for SVR4 /proc (process file system) support.
116 * tm-amix.h, xm-amix.h, tconfig/amix, xconfig/amix: New files for
119 * xm-svr4.h, tm-svr4.h: New files for SVR4 support.
121 * xm-m68k.h: New file for host machines with m68k cpu.
123 * Makefile.in: Add elfread.c and dwarfread.c to SFILES_MAINDIR.
124 Add elfread.o and dwarfread.o to OBS.
126 * symfile.h: Add "elf" to list of supported formats in comment.
128 * c-exp.y, defs.h, symtab.h, valprint.c: Add three new builtin
129 types to gdb, builtin_type_long_double, builtin_type_complex, and
130 builtin_type_double_complex. Add and use new TARGET_SHORT_BIT,
131 TARGET_INT_BIT, TARGET_LONG_BIT, TARGET_FLOAT_BIT,
132 TARGET_DOUBLE_BIT, TARGET_LONG_DOUBLE_BIT, TARGET_COMPLEX_BIT, and
133 TARGET_DOUBLE_COMPLEX_BIT, as the sizes in bits of the indicated
134 types on the target machine (ala the existing TARGET_LONG_LONG_BIT).
136 * infrun.c: When using SVR4 /proc interface instead of ptrace(),
137 call proc_set_exec_trap() to setup child to stop at first instruction.
139 * inftarg.c: When using SVR4 /proc interface, call proc_wait()
142 * m68k-tdep.c: Add new routines supply_gregset(), fill_gregset(),
143 supply_fpregset(), and fill_fpregset(), which are machine
144 dependent support routines for SVR4 /proc interface.
146 * utils.c: Add warning_setup() and warning(). Warning() behaves
147 the same as error() except that it returns normally rather than
148 jumping back to command level. Modules that don't want to call
149 warning() for some reason, but want to produce their own warnings,
150 can call warning_setup() to ensure compatibility with the way
151 warning() and error() deal with the terminal.
153 * symtab.c: Make internal errors produce more useful messages.
155 * tm-68k.h: Move code that is duplicated in almost every single
156 m68k based machine's configuration files to this common file.
157 Duplications in the configuration files still need to be removed
160 * infrun.c (child_create_inferior): System V versions must call
161 setpgrp() with no arguments, to comply with prototyping typically
164 * munch: Add support for SVR4 style nm output.
166 * dbxread.c, mipsread.c symmisc.c, symtab.c: Remove the object
167 file specific fields from the partial symbol table structure and
168 replace them with a pointer to private data for each different
169 flavor of object file reader to initialize appropriately.
171 Wed Oct 23 09:38:20 1991 John Gilmore (gnu at cygnus.com)
173 * xconfig/sun[34]os4: Add note about strstr botch on sunos4.0.3c
176 * mipsread.c (fixup_undef_type): New function. If a struct /
177 union / enum is defined in a header file but nowhere else used,
178 (by typedefing, pointer referencing or declaration) the mipsread code
179 builds the complete tree for the structure but leaves its code as
180 TYPE_CODE_UNDEF as it doesn't know what kind of aggregate it is.
181 Guess its type based on the details of the members.
183 Tue Oct 22 18:04:32 1991 Stu Grossman (grossman at cygnus.com)
185 * infrun.c (wait_for_inferior): Check return value from
188 Mon Oct 21 17:47:03 1991 Stu Grossman (grossman at cygnus.com)
190 * infrun.c (wait_for_inferior): fix stepi/nexti that was broken
191 by my last edit to this routine.
193 Mon Oct 21 14:27:43 1991 John Gilmore (gnu at cygnus.com)
195 * tm-sun3.h (FIX_CALL_DUMMY): problem with cross debugging.
196 FIX_CALL_DUMMY does unaligned accesses and/or forgets to byte swap
197 the values before putting them into the dummy code. (From Peter
200 Mon Oct 21 10:04:39 1991 Steve Chamberlain (steve at rtl.cygnus.com)
202 * configure.in: added ebmon target.
204 Wed Oct 16 22:49:58 1991 John Gilmore (gnu at cygnus.com)
208 * Makefile.in: Roll VERSION to 4.2.
209 * README, TODO, WHATS.NEW: Update.
211 * core.c (core_open): Improve error message for bad file.
212 Pass .reg virtual memory address to fetch_core_registers to help
213 it find the registers in the core-file header.
214 * coredep.c (fetch_core_registers): Take new argument, use it,
215 and pass it to register_addr to locate the block of registers.
216 * xm-mips.h: Update KERNEL_U_ADDR for new scheme. Cleanup a bit.
218 * dbxread.c (read_dbx_symtab, process_one_symbol): Handle
219 Sequent N_FN_SEQ like everybody else's N_FN.
221 * main.c: Circumvent SCO cc bug with #if !!defined(USG).
222 * tm-i386v.h: #endif guck.
223 * xconfig/i386*: Remove -Dgetpagesize()=4096 kludge.
224 * xconfig/i386sco: Add HAVE_STRSTR to avoid ANSI bdeath.
225 * xconfig/tahoe: Add REGEX, which seems to be missing.
227 * coredep.c: Add <sys/types.h> for SCOnix.
228 * dbxread.c (read_dbx_symntab): Avoid coredump on malformed file.
229 * printcmd.c (print_formatted): Flush output before disassembly.
231 Tue Oct 15 20:12:32 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
233 * doc/refcard.tex (sec "Working Files"): consistent metavars and
234 other improvements, due to comments by François Pinard
235 (pinard@iro.umontreal.ca)
237 * doc/gdb.texinfo (appendix "Installing GDB"): changes in
238 configure, and improvenets related to Pinard's refcard comments
240 Tue Oct 15 08:45:12 1991 John Gilmore (gnu at cygnus.com)
242 Changes from Fred Fish:
243 * tm-68k.h (FPI_REGNUM): Add.
244 * infrun.c (child_create_inferior): flush stdout and stderr

257 * i387-tdep.c (double_to_i387): Fix typo for double_to_ieee_extended.
258 * utils.c (_initialize_utils): If !ISATTY, don't paginate.
259 * configure.in, tconfig/decstation, xconfig/decstation: Rename
260 dec3100 to decstation.
262 Mon Oct 14 13:37:50 1991 Roland H. Pesch (pesch at cygnus.com)

276 generic routines for calling inferior functions.
278 * blockframe.c (inside_main_scope, inside_entry_scope): New.
280 * copying.awk: Filter formfeeds out of copying & warrantee.
281 Make them available as `show copying' and `show warrantee' also.
282 * main.c (print_gnu_advertisement): Advt `show' commands.
284 Thu Oct 10 17:25:47 1991 John Gilmore (gnu at cygnus.com)

287 core-file reading code.
288 * core.c (get_core_registers): Avoid coredump if no .reg section.
290 Wed Oct 9 17:03:34 1991 John Gilmore (gnu at cygnus.com)
292 * mipsread.c, coffread.c: initialise TYPE_VPTR_FIELDNO to -1.
293 This avoids coredumps under `set print object on' in value_headof
294 (called erroneously by value_from_vtable_info) for `p &struct'
295 or `p *struct'. From Peter Schauer.
297 Mon Oct 7 00:06:52 1991 John Gilmore (gnu at cygnus.com)
299 * Makefile.in: Roll version to 4.1.2.
300 * dbxread.c: Use aout64.h, not a.out.gnu.h. Get external symbol entry
301 size from BFD (but, FIXME, we don't yet read external nlists's and
302 convert them to internal nlists's before handling them -- we still
303 assume they have the same size and alignment.) Use SET_NAMESTRING
305 * exec.c (exec_file_command): Move dead coff-encapsulation code
307 * m88k-tdep.c, m88k-xdep.c: Remove encap test and #inc <a.out.h>.

311 * configure.in, tm-i386v.h, xm-i386v.h: Intel 386 Mach host port.
312 * xm-i386mach.h, mach386-xdep.c, xconfig/i386mach: New files.
314 Fri Oct 4 17:04:31 1991 Per Bothner (bothner at cygnus.com)
316 More patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
317 * mips-xdep.c (store_inferior_registers): Don't try to
318 write the (pseudo) FP.
319 * mipsread.c (parse_partial_symbols): Improved algorithm for
320 setting pst->texthigh.
322 Fri Oct 4 16:47:32 1991 Roland H. Pesch (pesch at cygnus.com)
324 * doc/Makefile: make TEXINPUTS include . everywhere
326 Fri Oct 4 00:35:56 1991 John Gilmore (gnu at cygnus.com)
328 * coffread.c, dbxread.c, symfile.c, symmisc.c, symtab.h: Remove
329 vestiges of typevectors, which were for symsegs and are no longer
330 used. (From a question by Eliot Dresselhaus
331 <dresselh@RFT30.nas.nasa.gov>).
333 Thu Oct 3 09:33:26 1991 John Gilmore (gnu at cygnus.com)
335 * dbxread.c, coffread.c: static-ize functions that were
336 gratuitiously external. (From Fred Fish.)
338 * c-exp.y: sym->class to SYMBOL_CLASS (sym).
340 * dbxread.c (dbx_lookup_type): Keep doubling size of typevector
341 until it is large enough.
343 * dbxread.c (read_type): Handle error case slightly better.
344 Make complaint message not C++-specific.
346 Wed Oct 2 17:21:07 1991 Stu Grossman (grossman at cygnus.com)
348 * infrun.c (wait_for_inferior): Fix step/next so that you only
349 stop at the beginning of a new line. This fixes various problems
350 with for loops, nested if-else's and switch statements.
352 Tue Oct 1 06:33:55 1991 John Gilmore (gnu at cygnus.com)
354 * symtab.c (lookup_symtab_1, lookup_symbol): "fatal" errors
355 between symtabs and psymtabs become ordinary error()s.
357 * dbxread.c (read_dbx_symtab): Relocate end_of_text_addr
358 properly, making "end pc" correct in shared lib psymtabs.
359 (From Guy Harris <guy@auspex.com>.)
361 Mon Sep 30 13:15:31 1991 John Gilmore (gnu at cygnus.com)
363 * dbxread.c: Enable, but soften, const_vol_complaint.
364 (read_dbx_symtab): N_STSYM and N_LCSYM define static vars.
365 Ditto Gould N_NBSTS and N_NBLCS. Also, all types in the psymtab
366 should be file-scope, not global.
367 (read_struct_type): Remove ancient multiple-inheritance warning.
368 (read_range_type): Check base type, complain & patch if undefined.
369 * stack.c (frame_info): Demangle the function name in `info stack'.
372 Sat Sep 28 10:02:33 1991 John Gilmore (gnu at cygnus.com)
374 * eval.c (evaluate_subexp_for_address): Don't use
375 TYPE_POINTER_TYPE directly (it might be zero if this type has
376 never had a pointer created before); use lookup_pointer_type.
377 * symtab.c (lookup_method_type): Arguments were swapped in all
378 callers, so fix it here. I'm amazed this worked at all!
380 Fri Sep 27 18:09:31 1991 John Gilmore (gnu at cygnus.com)
382 * c-exp.y, m2-exp.y: Define more yysymbols that happen to be
383 "bss" rather than "data" symbols, but which still conflict.
386 * coffread.c (coff_symfile_read): Use xmalloc, not malloc.
387 * core.c (core_files_info): Shorten output.
388 * exec.c (exec_files_info): Ditto.
389 (build_section_table): Ignore zero-length sections.
390 * language.c, printcmd.c: Lint.
391 * language.h (get_frame_language): Declare.
392 * saber.suppress: update.
393 * stack.c (find_relative_frame): Remove complex code that was

403 * nindy-tdep.c (nindy_frame_chain_valid): Use lookup_misc_func.
404 (Reported by Mark Peek <mark@imagen.com>.)
406 * solib.c (solib_map_sections): Relocate all sections, even
407 though only the text section's size is tracked. Mark ld_text
408 for eventual elimination as we generalize to N sections.
410 * infrun.c (wait_for_inferior): Don't check if the PC is in a
411 call_dummy if we were stopped by a random signal that is being
412 passed to the program. This produced wierd results when calling
413 functions in the inferior and signals (e.g. SIGALRM) were in use.
415 Tue Sep 24 18:05:30 1991 John Gilmore (gnu at cygnus.com)
417 * infrun.c (IN_SIGTRAMP): Not parenthesized properly.
418 Bugfix from Paul Eggert <eggert@twinsun.com>.
419 * tm-ultra3.h (IN_SIGTRAMP): Ditto.
420 * valprint.c (print_floating): Print 9 digits for IEEE floats.
423 Mon Sep 23 15:50:07 1991 John Gilmore (gnu at cygnus.com)

429 Fri Sep 20 16:10:52 1991 John Gilmore (gnu at cygnus.com)
433 * Makefile.in (VERSION): Set to 4.1.
434 * language.c (set_language_command): Print useful help message,
435 and restore the language string after giving help.
436 * valprint.c (typedef_print): Print typedef in C or M2.
437 * symtab.c (list_symbols): Use it.
438 * main.c (main): Avoid any output before (gdb) prompt when -q.
439 * language.c (set_language_command): Handle errors by restoring
440 the language string to its current state (fix from A. Beers).
441 * doc/gdbint.texinfo: Roll in information from README. Rearrange
442 "how to install" and "how to print the doc" stuff so it drops
444 * configure.in: Rename rtpc CPU to romp to match config.sub.
445 * README, WHATS.NEW, TODO: Update for gdb-4.1.
447 Fri Sep 20 17:39:14 1991 Roland H. Pesch (pesch at cygnus.com)
449 * doc/gdb.texinfo: Updates from ChangeLog. set/show write,
450 autoloading shared libs, copyright etc on GDB startup, clean up $_
451 and $__ index refs, set/show listsize and related updates to list
452 cmd. New host/target configs.
454 Fri Sep 20 15:46:00 1991 Roland H. Pesch (pesch at cygnus.com)
456 * doc/Makefile: generate aux version-no file doc/gdbVN.m4
457 from main Makefile.in version definition
458 doc/gdb.texinfo: use version recorded in doc/gdbVN.m4 for current
460 Makefile.in (setup-to-dist): generate doc/gdbVN.m4
462 * doc/gdb.texinfo: merge new language-switching and lang-specific
465 Fri Sep 20 15:00:57 1991 Per Bothner (bothner at cygnus.com)
467 * mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
468 compilers (which may lack stddef.h).
470 Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com)
472 * dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and
473 N_WARNING are the same except for the N_EXT bit, so just use their
474 values alone, rather than OR-ing them with N_EXT.
476 Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com)
478 * mipsread.c (parse_lines): Deal with negative extended line
481 * c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid
482 global symbol conflicts.
484 Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
486 * .gdbinit: Move 'set complaints' to top, so it runs even in
487 case we aren't debugging GDB.
488 * language.c (_initialize_language): Fix type check and range
489 check documentation strings.
490 * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
491 language.c can use it. (Though language.c should really not be
492 handling warnings/errors the way it does, FIXME.)
493 * symtab.c (lookup_primitive_type): const lint.
495 Bugfix from Peter Schauer:
496 * source.c (lines_to_list): Make signed, to avoid comparison
497 going unsigned and complaining that -3 is too high for 21 lines.
498 * stack.c (lines_to_list): Ditto.
500 Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
502 * Makefile.in (HFILES): Add minimon.h.
503 (VERSION): Roll version number to 4.0.95.
504 (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
505 New rules for building distributions. Normal distribution
506 is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
507 one level up from here; it calls make-proto-gdb.dir to build a
508 directory `proto-gdb' which is an image of the release. The old
509 `gdb.tar.Z' rule still works too.
510 * config.sub, configure: Roll in latest from ..
512 Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
514 * doc/gdbint.texinfo: Reorder contents; reorganize new-host,
515 new-target, and new-config chapters; fix minor typos; come closer
516 to usual GNU markup conventions for @file @samp @code @var.
518 Thu Sep 19 17:04:12 1991 Per Bothner (bothner at cygnus.com)

636 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
638 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
639 entries are enclosed herein. Not all of these changes
640 have been merged into the master GDB sources -- check the
641 ChangeLog above here for the merge log.
643 Mon Jun 3 17:05:45 EDT 1991
645 m2-exp.y Created. Tested outside of GDB for a few days. Proper
646 operators were added, C specific operators and tokens
647 removed. yylex() revamped to some extent. Still things
648 missing from the grammar, such as sets.
649 Tested for two weeks in GDB v3.5.
651 Tue Jun 11 17:23:48 EDT 1991
653 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
654 so they are built-in. Sort of a hack.
656 Fri Jun 14 12:53:51 EDT 1991
658 m2-exp.y Added range checking for numeric constants. Any numeric
659 constant is assumed to be of builtin type INTEGER unless:
660 (1) it is octal or hexadecimal, in which case it is a
661 CARDINAL; (2) it is too big to fit into an INTEGER, in
662 which case it is a CARDINAL.
663 eval.c Added simple range checking for +, -, and * on integers.
664 Doesn't work very well for *, since 6 * 1,000,000,000 =
665 1,705,032,704, which fails the simple test of result >=
666 first_operand, no matter in what order the operands are.
668 Tue Jun 18 14:11:30 EDT 1991
670 Broke the parser into parts, one containing the C grammar and the other
671 containing code to be shared by all of the grammars.
673 The following files no longer exist:
678 The following files were added:
680 c-exp.y (The C grammar)
681 m2-exp.y (The Modula-2 grammar)
682 parser-code.c (Code that is shared by the above grammar)
686 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
687 now necessary to use the Bison compiler compiler, since it
688 will generate function/variable prefixes other than yy.
690 Tue Jun 18 16:47:49 EDT 1991
692 symtab.[ch] Added the external variable working_lang, than holds the
693 value of the current working language.
694 Added the ennumerated type language_mode, with the values
695 language_auto and language_manual, the former meaning that
696 GDB sets working_lang as needed, and the latter meaning
697 that the value of working_lang is totally under user
699 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
700 REAL, BOOLEAN and CHAR. Also added the type codes
701 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
702 utils.c Added set_language_command and show_language_command to
703 implement the GDB support commands "set language" and
705 expression.h A number of identifiers were added to the type exp_opcode
706 to facilitate Modula-2 builtin functions, integer
707 division, and array indexing.
709 Wed Jun 19 13:25:58 EDT 1991
711 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
712 if the language specified by working_lang requires the use
713 of strict typing of expressions. Eventually, even this
714 will be able to be changed by the user.
715 Added the macro RANGE_CHECK, which evaluates to non-zero
716 if the language specified by working_lang requires the
717 checking of a value against the domain of its type.
718 Eventually, even this will be able to be changed by the
720 language.[ch] Predicates involving types (simple_type, ordered_type,
721 same_type, integral_type, numeric_type, character_type,
722 boolean_type, float_type) are added. These predicates are
723 based on the current value of working_lang, and are handy
726 Wed Jun 19 15:39:34 EDT 1991
728 eval.c Added the function type_array_rank which computes the rank
730 valarith.c Added the funtion value_bool, which when given a integer
731 value.h value (ie. struct value *) as an argument, it returns a
732 boolean value (ie. struct value *) true if that integer
733 is non-zero, and a boolean value false otherwise.
734 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
735 will print out properly.
737 Wed Jun 19 16:36:34 EDT 1991
739 valops.c Added the function value_capitalize, which returns it
740 value.h argument capitalized if its argument is a lowercase
741 letter, or the argument unchanged if its argument is not a
743 valarith.c Added the function range_check_p, which returns non-zero
744 value.h if its value argument is between the integral bounds upper
746 Added the function range_check_enum_p, which makes sure
747 that its value argument is a valid member of the domain of
749 Added the function range_check_range_p, which makes sure
750 its value argument lies between the upper and lower bounds
751 of its type argument, which must be a ranged type.
752 Added the function check_array_index, which range and type
753 checks an index of an array.
754 Added the function value_multi_subscript, which computes
755 array[idx1,idx2...idxN], given a value array and an array
756 of values representing indicies.
757 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
758 unpack_long to work with TYPE_CODE_BOOL and
761 Wed Jun 19 18:04:08 EDT 1991
763 symtab.c Stored pervasive types in a structure and make
764 lookup_pervasive_type() a lookup function that was based
765 on working_lang. If lookup_pervasive_type() returned
766 non-zero, then that value was returned (a fix, since
767 before it simply wouldn't return the pervasive type.)
768 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
769 non-zero if the language specified by working_lang means
770 "conversion" when it says "cast".
771 valops.c Added the function value_real_cast(), which performs a
772 value.h *cast*, not a *conversion*, which is what value_cast()
773 does when it can. In particular,
774 value_cast(<float_type>,4) = 4.0, while
775 value_real_cast(<float_type>,4) = some mess.
776 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
777 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
778 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
779 and MIN on integral types. *NOTE*: These are currently
780 hardcoded to work only if there are 8 bits per storage
782 eval.c Made logical functions call value_bool to return a
783 properly typed boolean value, based on working_lang.
785 Thu Jun 20 11:55:27 EDT 1991
787 valprint.c Types now print out in a Modula-2 fashion. This works for
788 the cases when the type is printed out step-by-step, that
789 is, it doesn't work when the name of a structured type
790 (which includes the keyword "struct", etc.) is simply
792 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
793 since type specifications in C and Modula-2 are very
794 different. The C printing of a type is very recursive,
795 whereas in Modula-2 it is generally very simple. C has
796 type prefixes and suffixes, which have no real analogue in
797 Modula-2. Maybe type_print() should call a language
798 specific type printer. This is also advantageous if we
799 compile GDB to exclude some of the languages. We'll just
800 leave those functions out.
802 Thu Jun 20 16:57:10 EDT 1991
804 dbxread.c When reading the complete symbol table in (via
805 psymtab_to_symtab()), the number and types of function
806 arguments are added to a function type. define_symbol()
807 calls add_param_to_type() to accomplish this.
808 Assumption: when we come across a function definition
809 (N_FUN symbol with an 'f' or 'F' in the name), its
810 arguments will appear before another function definition.
811 When a function is found, a pointer to its type is placed
812 in the global in_function_type. Changes that
813 add_param_to_type() makes are to this global.
814 valprint.c The type of a function now includes (for Modula-2) the
815 types of its parameters.
816 eval.c Type checking and a check for the proper number of
817 arguments is now done for function calls. Not sure of the
818 impact this has on C++ member function yet.
820 Thu Jun 20 19:58:48 EDT 1991
822 valprint.c Rewrote the type printer. Broke it into two language
823 specific parts, adding the functions type_print_m2() and
825 An unfortunate consequence is this: if you debugging a C
826 program in Modula-2 mode (why?), info types does not work
827 well with regular expressions, since the types are printed
828 out in Modula-2 terminology, but stored in C terminology.
829 language.[ch] Added the functions new_type_last(), type_keyword(), and
830 type_sep() to aid in the printing of typedefs.
831 symtab.c Made the printing of typedefs as language independent as
832 possible through calls to new_type_last(), type_keyword(),
835 Fri Jun 21 11:50:26 EDT 1991
837 dbxread.c Check all incoming ennumerated types. If it looks like
838 Modula-2's BOOLEAN type, then change the type_code of the
839 type to TYPE_CODE_BOOL so we can process it as a boolean
841 valprint.c Replaced some of the 0x%x with calls to sprintf and
842 hexformat() in val_print().
843 language.[ch] Added the function hex_to_string(), which converts its
844 integral argument to a hexadecimal number (format is
845 language based) and returns the result as a string.
847 Mon Jun 24 12:25:07 EDT 1991
849 valprint.c Some functions call type_print_1() directly, instead of
850 value.h using type_print(), so they can specify where (column) to
851 print things. Since type_print() takes care of language
852 dependence, that needs to be called first. Added a
853 parameter depth to type_print() (so it is now like
854 type_print_1). Changed type_print to type_print_at, and
855 made type_print a macro that passes a depth argument of
857 symmisc.c Changed all calls to type_print_1 to calls to
859 Makefile.dist Made it possible to build GDB for a specific set of
860 depend languages. Do this by passing a definition for the macro
861 LANGS to make. LANGS should be a string containing a
862 space-separated list of language names (ie. LANGS="c m2").
863 The default is to build all languages. Note that grammar
864 files must follow the naming convention of <lang>-exp.y.
865 gdb.lang This holds the current value of the LANGS macro. It is
866 examined every time make is called, and is updated if
868 eval.c Added #ifdef _LANG_<lang> to these files.
869 expread.c Still need to add them to dbxread.c and coffread.c.
877 Mon Jun 24 16:33:11 EDT 1991
879 language.[ch] Added the functions hexformat_pre() and
880 hex_to_string_pre(), which take a prefix argument to
881 include in the format string. Thus, hexformat_pre("08") will
882 return "0x08x" (if the working language is language_c).
883 Made hexformat() and hex_to_string() calls to the above
884 with "" as the prefix argument.
886 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
887 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
888 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
889 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
890 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
891 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
892 valprint.c, vax-pinsn.c
894 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
895 calls to hexformat() and hex_to_string(). Format strings without
896 the leading "0x" were ignored.
898 depend Updated to take the above into account.
901 Tue Jun 25 15:27:18 EDT 1991
903 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
904 and type_check_t to keep track of the current state of
905 range and type checking.
906 main.c Added the variables range_mode, range_check, type_mode,
907 and type_check to record the current state of range and
908 type checking. Added initialization code to main().
909 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
913 Tue Jun 25 17:57:08 EDT 1991
915 dbxread.c process_one_symbol() updates the variable (enum language)
916 source_lang based on the extension of the filename
917 contained in the N_SO sybmol that started this symtab.
918 When end_symtab() is called, the value of source_lang is
919 put into the language field.
920 stack.c select_frame() sets working_lang (and possibly type_check
921 and range_check) to the language field of the symtab
922 associated with the frame that is selected if working_mode
923 is language_auto. If working_mode is language_manual, a
924 warning is printed and working_lang is not set.
925 language.c Added the function set_type_range(), which sets the value of
926 type_check and range_check (if their modes call for
927 automatic setting) based on the current value of
928 working_lang. A non-zero argument will cause the current
929 settings to be output.
932 Wed Jun 26 14:51:40 EDT 1991
934 eval.c Added range checks on assignment.
935 m2-exp.y Added the grammar for sets to the language. Currently,
936 these do not do anything except print an error message.
938 Wed Jun 26 17:01:04 EDT 1991
940 m2-exp.y Added the ability for parse_number() to parse negative
941 numbers. A global flag is set upon encountering a unary
942 minus. This was done to make, for example, 1 parse as a
943 CARDINAL, and not as an integer, per Wirth's examples in
944 Programming in Modula-2 ed.4.
945 valprint.c Added support for "set radix 2" by then setting
946 output_format to 't'.
947 eval.c Implemented range checking on subrange types. Added calls
948 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
949 Implemented MIN and MAX for ennumerated types. The
950 minimum value of an ennumerated type is defined by Wirth
951 as the first identifier, and the maximum as the last.
952 m2-exp.y Made octal numbers ending with "B" be characters and those
953 ending with "C" be numbers, per Wirth's book. (p. 34)
955 Thu Jun 27 14:11:52 EDT 1991
957 stack.c select_frame() now only sets working_lang, it does not
958 notify the user. If working_mode is language_manual, then
959 a warning is issued once.
960 main.c At the end of each call to execute_command(), working_lang
961 is checked against the local static (enum language)
962 current. If they differ and working_mode is
963 language_auto, the new settings of language, type and
964 range checking are printed out.
965 stack.c Modified frame_info() to include the language of the
966 current frame in the output of "info frame".
967 language.[ch] Added the function language_str() which returns the name
968 of the current language.
970 Fri Jun 28 15:33:14 EDT 1991
972 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
973 the language. INCL and DECL currently cause an error,
974 since sets are not implemented yet. INC and DEC are
975 implemented as PREINCREMENT/PREDECREMENT with one
976 argument, and as ASSIGN_MODIFY with two arguments.
977 eval.c Added type checking to the above cases.
978 value.h Added not_lval_constant to the lval_type ennumerated type.
979 not_lval_constant means that the value is a constant
980 value; that is 3 or 'a' or TRUE, not as in a constant
981 identifier. This is used to help coerce numbers such as 3
982 to either signed or unsigned numbers.
983 valops.c Added the function value_coerce_constants() which coerces
984 constant integers as following: if one is a constant and
985 the other is not, the constant's type is set to the type
986 of the other argument. If both are constants and one is
987 signed, the other is converted to a signed constant.
989 Sat Jun 29 17:26:29 EDT 1991
991 valarith.c Added a better range checker. It now checks range
992 (successfully) on integral operations [+-] (signed and
993 unsigned) for any C sized type. Still does not work well
995 int_in_size() returns an integer that is coerced to fit into
996 specified number of bytes.
998 Mon Jul 1 13:04:14 EDT 1991
1000 language.[ch] Added the function binop_result_type(), which returns the
1001 builtin (struct type *) type that would be the result of a
1002 binop on the two values V1 and V2.
1004 Wed Jul 3 19:22:53 EDT 1991
1006 source.c Extended source_info() to include the source language in
1007 the output from "info source".
1009 Fri Jul 5 13:48:52 EDT 1991
1011 utils.c Moved the support functions for the GDB set/show commands
1012 dealing with language into language.c.
1013 language.c Added the function language_info(), which displays info
1014 about the current working language, type and range check
1015 settings. Called via the GDB command "info language".
1016 Added an initialization routine _initialize_language(),
1017 that sets defaults for the language, type and range
1018 variables and sets up the new GDB commands.
1019 main.c Language setup moved to language.c.
1022 Mon Jul 8 10:10:22 EDT 1991
1024 valarith.c Debugged the range checker for arithmetic. Still does not
1025 work for multiplication very well.
1027 Mon Jul 8 12:40:37 EDT 1991
1029 language.[ch] Added the function value_true() which returns non-zero if
1030 its argument represents a boolean true value.
1031 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
1032 check the truth of an expression.
1034 Thu Jul 11 12:51:34 EDT 1991
1036 language.[ch] Added the predicate structured_type(), which returns
1037 non-zero if the argument is a structured type.
1038 Added the predicate pointer_type(), which returns non-zero
1039 if the argument is a pointer type.
1040 eval.c Added the ability to do addition and substraction on
1041 pointers and integers. This case simply bypasses the
1044 Thu Jul 11 14:41:42 EDT 1991
1047 Added the symbol N_DEFD (0x4a) which is a definition
1048 module dependency that is used by the GNU Modula-2
1049 compiler and the linker. It is not important to GDB,
1050 except that [dbx|coff|mips]read.c should ignore these
1053 Fri Jul 12 16:07:00 EDT 1991
1055 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
1056 0 in val_print(). Also added statements to the else part
1057 to coerce type (argument to val_print) to a pointer type
1058 if it is an "array of unspecified length".
1059 valops.c Added the function value_m2_string(), which returns a
1060 (value) value which is a constant string, whose type is
1061 (ARRAY [0..n] OF CHAR). The length field of the type
1062 structure is set to zero, so it will be interpreted as an
1063 "array of unspecified length".
1064 stack.c Moved the language/frame mismatch check to
1065 main.c:execute_command().
1066 main.c The working language is recorded each time
1067 execute_command() is executed. If working lang has
1068 changed during its execution, then the new
1069 language/type/range info is printed out for the user. If
1070 the working language does not match the language of the
1071 frame, a warning is issued.
1073 Sat Jul 13 16:16:39 EDT 1991
1075 eval.c Moved all the type-checking stuff for operators to
1076 language.[ch] language.c. This is so we can keep language-specific
1077 stuff (like for what type operators are defined) in
1079 language.[ch] Added the function binop_type_check(), which checks to see
1080 if its two (value) arguments are type-compatible with its
1081 opcode argument. The opcode should represent an operation
1082 involving an operator. Also added the macro function
1083 unop_type_check, which calls binop_type_check with a
1084 NULL second argument.
1085 expprint.c Added Modula-2 operators to the op_print_tab, so info
1086 expression.h break works correctly. Also added "op_string", which
1087 returns the string corresponding to the (enum exp_opcode)
1088 opcode that is its argument.
1091 Sat Jul 13 18:26:18 EDT 1991
1093 coffread.c Added code to record the type of function arguments with
1094 each paricular function. Code is very similar to that
1096 dbxread.c Moved add_param_to_type() to symtab.c
1097 symtab.[ch] Added function add_param_to_type() from dbxread.c
1099 *** NOTE: The above additions have not been tested.
1101 Mon Jul 15 12:50:47 EDT 1991
1103 langauge.[ch] Added the functions type_error and range_error, which work
1104 like error() except if the type/range mode is set to
1105 *_mode_warn, then they do not do a return_to_top_level(),
1106 but merely print a warning.
1107 Also changed [set|show]_[type|range]_command() to support
1108 the new "warn" feature.
1110 Thu Jul 18 17:50:54 EDT 1991
1112 mipsread.c Added code to record the type of function arguments with
1113 each particular function. Code is very similar to that
1116 *** NOTE: The above additions have not been tested.
1118 Fri Jul 19 11:19:10 EDT 1991
1120 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
1121 UMIN_OF_SIZE, which when given a size of a numeric type,
1122 return the maximum and minimum value it can hold. UMAX...
1123 and UMIN... return the result for unsigned types.
1124 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
1125 struct types. They call above macros.
1126 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
1127 avoid a name conlict with the above.
1128 c-exp.y Added range checking on numeric constants in
1129 parse_number() for completeness.
1130 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
1131 return 0 if working_lang is not language_c.
1133 Thu Aug 8 14:17:22 EDT 1991
1137 breakpoint.c Documentation strings of some commands changed to
1138 eliminate the references to the C language where
1141 Tue Aug 13 15:48:03 EDT 1991
1143 m2-exp.y Added qualified identifiers to the grammar. The semantics
1144 are slightly different from those of the GDB operator ::
1146 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
1147 type_exp, where type_exp is any valid type expression.
1149 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
1150 printcmd.c Modified ptype_command() so it actually parses the input
1151 (necessary for type expressions with scope qualifiers).
1152 Added the function ptype_eval() which expects an
1153 expression composed of one OP_TYPE element.
1154 *.[ch] Replaced all occurences of parse_c_expression with
1156 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
1158 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
1160 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
1162 Small fixes from Peter Schauer:
1164 * infrun.c (child_attach): Lint.
1165 * solib.c (find_solib): Handle shared libs version 2.
1167 Small fixes from David Wood:
1169 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
1173 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
1174 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
1176 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
1177 chars_per_line is at maximum (user typed `set width 0'). Fix
1178 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
1180 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
1182 * coredep.c: include ptrace.h where necessary.
1183 * mipsread.c(parse_lines): fix unsigned char problem that was
1184 messing up line numbers on SGI's and possibly other MIPS based
1186 * infrun.c (child_create_inferior): use better test to check
1187 return val from setpgrp().
1188 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
1189 for sgi/irix support.
1191 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
1193 * mipsread.c (parse_symbol): Put non-static procedures
1194 in the global block.
1196 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
1198 Patch together `text_start' and `text_end' for 29K port.
1200 * exec.c (exec_command): If NEED_TEXT_START_END, define the
1201 variables and set them based on the exec file.
1202 * am29k-tdep.c: declare text_start.
1203 * valops.c (call_function_by_hand): declare text_end.
1205 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
1206 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
1207 because machines that do this will also have to know to
1208 set NEED_TEXT_START_END. Besides, it was a redundant way to
1210 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
1211 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
1212 NEED_TEXT_START_END.
1214 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
1216 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
1218 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
1219 Pass MUNCH_DEFINE to munch whenever we run it.
1220 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
1221 format string; use 0x%x instead.
1222 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
1223 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
1224 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
1225 * inflow.c: Handle `short' process group IDs.
1226 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
1227 and check for ptrace errors.
1228 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
1229 (coff_symfile_init): Initialize text_bfd_scnum.
1230 (read_coff_symtab): Use it to find the text [and absolute?] sections.
1231 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
1232 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
1233 Merge target arm case with other "easy" cases. Add target
1234 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
1235 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
1237 * minimon.h, remote-adapt.c, remote-mm.c: Add.
1238 * munch: Cope with RT/PC putting fns in data segment.
1239 Restore ability to override `nm' by specifying MUNCH_NM.
1240 * xconfig/rtbsd, xconfig/ultra3: New host systems.
1241 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
1242 and remote-adapt. Remove encapsulated coff #define's (the
1243 support should go in BFD, and gdb shouldn't know or care).
1244 * tconfig/a29k-kern: Same, but for remote kernel debugging.
1245 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
1246 * tm-29k.h: Update BADMAG (though it should go away).
1247 Allow the register definitions to be overridden in another
1248 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
1249 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
1250 DUMMY_SAVE_GR96, for handling kernel calling conventions
1251 that use GR64+ rather than GR96+.
1252 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
1253 remote debugging of Ultra3 kernel. Includes tm-29k.h and
1254 overrides various things.
1256 * remote-mm.c (mm_attach, mm_wait): Handle attach like
1257 child_attach does, making a clean stop in the newly attached
1259 * remote-eb.c: Lint.
1261 * coffread.c: Make coffread independent of any particular
1262 variant of COFF. Avoid #include-ing any particular one except
1263 internalcoff.h. BFD now passes key values for symbol reading
1264 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
1265 and the symbol masks and shifts); use them.
1266 Remove obsolete end_of_text_addr.
1268 * exec.c: Remove unused include files.
1270 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1272 * Makefile.in (documentation targets): Pass $(M4).
1273 Bugfix from eggert@twinsun.com (Paul Eggert).
1275 * stack.c (down_silently_command): Check for stack existence.
1277 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1279 * Makefile.in (VERSION): Update to 4.0.3.
1281 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1283 * core.c (core_file_command): Print frame at coredump with
1284 its level number, by calling print_stack_frame.
1285 * frame.h: Add selected_frame_level, print_stack_frame.
1286 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
1287 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
1288 Change print_sel_frame and print_selected_frame callers to
1291 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
1292 * symfile.c (free_named_symtabs): Ditto.
1293 * main.c (main): wrap_here needs an arg.
1294 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
1295 (solib_add): Avoid noise.
1296 (solib_create_inferior_hook): Lint.
1297 (sharedlibrary_command): Move dont_repeat to here.
1298 * utils.c (error): Call wrap_here to force buffered output.
1300 Small patches from Peter Schauer:
1302 * coffread.c (start_symtab): Free any existing line_vector before
1304 (read_coff_symtab): Ditto for type_vector.
1306 * source.c (lines_to_list): New variable, replacing function.
1307 (all uses): Use as variable.
1308 (_initialize_source): Add 'set listsize' and 'show listsize'.
1309 * utils.c (lines_to_list): Remove function.
1310 * stack.c (print_frame_info): Use as variable.
1311 * defs.h (lines_to_list): Remove declaration.
1313 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1315 * breakpoint.c (insert_breakpoints): Restore warning about
1316 the program might be running in another process, but only for
1317 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
1318 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
1320 * utils.c (error): if error_pre_print is set, print the string
1322 * main.c (main, print_gnu_advertisement, print_gdb_version):
1323 Reformat legalese so it always prints, but acts as an "I'm here"
1324 message while symbols are being read. If any errors occur,
1325 print a few newlines to set off the message and start it at the
1326 left margin. Remove mention of "help" command, and don't yak
1327 about symbol reading.
1328 (catch_errors): Error string is now printed first in case of
1330 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
1331 suggest the "help" command.
1333 * Makefile.in (VERSION): Set to 4.0.2.
1335 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
1337 * .gdbinit: Remove useless "rr" command. Set complaints
1338 to 1 for people debugging gdb.
1340 * breakpoint.c, remote-vx.c: Reword strings printed by
1341 catch_errors callers.
1343 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
1345 * WHATS.NEW: "history write -> history save". Doc "write on/off".
1346 (Fix from kenc@viewlogic.com.)
1348 Fix some infrastructure to be able to cope with host and target
1349 machines with different sized basic types (ints, ptrs, etc).
1350 (Idea from pierre@la.tce.com (Pierre Willard).)
1352 * values.c (value_from_longest): Rename from value_from_long.
1353 Handle pointer types as well as integers, so that targets with
1354 different pointer sizes from the host can be accomodated.
1355 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
1356 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
1357 uses of value_from_long to value_from_longest.
1358 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
1359 the correct pointer type to value_from_long{est}.
1361 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
1363 * remote-vx.c: Remove obsolete code for calling functions via
1364 vxworks kludge interface (it referenced value_from_long).
1366 * valops.c (value_string): Find malloc with lookup_misc_func, not
1369 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1371 Make writing to files work properly. (Fixes to BFD are also needed.)
1373 * core.c (core_open): Open file ourselves, read or r/w, depending on
1374 write_files. Use bfd_fdopenr.
1375 * gdbcore.h (write_files): New variable.
1376 * exec.c (write_files): Define variable, add set&show for it.
1377 (exec_file_command): Use write_files to open for read or r/write.
1379 Make shared library reading happen automatically. These changes
1380 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
1382 * inferior.h (stop_soon_quietly): Add to exported variables.
1383 * infrun.c (child_create_inferior): call solib hook, if defined.
1384 (child_attach): call solib hook, if defined.
1385 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
1386 (find_solib): Use lookup_misc_func rather than hand-rolled.
1387 (symbol_add_stub): New stub for catch_errors.
1388 (solib_add): Avoid output if !from_tty. Catch errors rather
1389 than just calling symbol_file_add and bombing.
1390 (solib_create_inferior_hook): Interface with the target process
1391 to let it read and alloc shared libs, then figure out what it did.
1393 * core.c (validate_files): Fix typo, soften warning.
1394 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
1396 * utils.c (fputs_demangled): Avoid duplicate printing if
1397 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
1399 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
1400 (Fix from pierre@la.tce.com (Pierre Willard).)
1402 * main.c (catch_errors): Change argument to a char * from an int,
1403 since a char * can point to a struct full of glop, but an int
1404 is not guaranteed to be able to hold a pointer.
1405 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
1406 breakpoint_re_set_one, breakpoint_re_set): Adapt.
1407 * core.c (core_open, solib_add_stub): Adapt.
1408 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
1410 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1412 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
1413 by adding .NOEXPORT target.
1415 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1419 * Makefile.in (VERSION): Roll to 4.0.
1420 (gdb.tar.Z): Make refcard.ps as well, for shipment.
1422 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1424 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
1427 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
1430 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
1432 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
1433 reflect above name change
1435 * WHATS.NEW: correct pointer to refcard.
1437 * doc/gdb.texinfo: update New Features, Installing
1439 * doc/gdbint.texinfo: add short description of configure +template
1441 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1443 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
1445 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
1447 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
1448 tar file, add dependencies for referenced doc files.
1450 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
1452 * coffread.c, symfile.c, stack.c: saberized.
1454 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1456 * doc/refcard.tex: permuted Essential Commands sec
1458 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
1460 set/show symbol-reloading
1461 default set complaints 0
1463 RET-repeat disabled after prompted long displays
1464 processID (attach) interpretation of 2nd GDB cmdline arg
1466 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
1468 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
1469 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
1470 breakpoint.c, main.c: lint.
1472 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1474 Install new configuration scheme for GDB and friends.
1476 * config.sub: Translate ordinary names to three-part names.
1477 * configure: Use three-part names internally.
1478 * configure.in: Translate three-part names to filenames.
1480 * README, WHATS.NEW: Update for gdb-4.0.
1481 * Makefile.in: Roll VERSION to 3.99.
1483 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
1485 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
1486 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
1487 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
1488 to single structures rather than arrays; when passing
1489 their address, use &. This avoids trouble with bdead compilers.
1490 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
1491 instead. This avoids portability headaches.
1492 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
1494 * source.c (open_source_file): Avoid ANSI const bdeath by
1495 skipping declaration and then casting result value.
1496 * tm-hp300bsd.h: Clarify comment.
1497 * utils.c (strstr): Result is const char *; ANSI bdeath.
1498 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
1499 since system include file defines it differently from "defs.h",
1500 though the two are equivalent for our purposes.
1501 * tconfig/hp300bsd: Add m68k-tdep.o.
1503 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1505 * tconfig/sun*4: Remove warnings about system assembler.
1507 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1509 * mcheck.c: Avoid warning about undeclared abort fn.
1510 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
1511 it causes recursive calls to error() when used in cleanups.
1512 To do so requires that we make it a function, so we do.
1513 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
1514 * utils.c (do_cleanups): Remove the current cleanup from the
1515 chain *before* calling it, in case error() is called from it.
1516 The result won't be pretty, but won't be an infinite loop either.
1518 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
1520 * dbxread.c (read_struct_type): Grok anon structs for C++.
1521 (vb_name, vptr_name): Null terminate these strings.
1523 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1525 Minor bug fixes from BSD Net2 gdb:
1527 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
1528 returns 0, there is no previous frame.
1529 * breakpoint.c (commands_command): If !from_tty, don't call
1530 input_from_terminal_p().
1531 * dbxread.c (record_misc_function): Speed up slightly.
1532 (compare_psymbols): Ditto.
1533 * infcmd.c (do_registers_info): Take a second argument to
1534 determine whether to print float registers. "info registers"
1535 does not do so anymore. "info all-registers" does, now.
1536 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
1538 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
1539 * inflow.c (initialize_inflow): Set tflags_ours correctly.
1543 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
1544 executing_breakpoint_commands if we are interrupted by error.
1545 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
1546 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
1547 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
1548 catch_errors() so we can setup the frame regardless of whether
1549 the shared libs work.
1550 * ieee-float.c (double_to_ieee_extended): Get exponent from
1551 right place in little-endian systems. From John Carey.
1553 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1555 * main.c: Remove unused terminating_signals and catch_termination().
1556 (long_options): Terminate with a zero element.
1557 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
1558 (gdb_readline): Make call-compatible with readline.
1559 (init_signals): Improve comments re vfork vs. signal.
1561 * utils.c (prompt_for_continue): Use new gdb_readline().
1562 If we prompt for continuation, we don't let CR repeat the previous
1563 command, once we get back to a prompt. It's too easy to keep
1564 hitting CR, expecting "--more--" prompts, and have some long
1565 command start repeating on you.
1567 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1569 * blockframe.c (frameless_look_for_prologue): Speed up by
1570 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
1571 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
1572 Define two variants, one faster.
1573 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
1574 and return zero, rather than giving an error.
1575 (setup_arbitrary_frame): Initialize the PC in the new frame.
1576 (skip_prologue): Add a second arg saying whether we're just
1577 checking for a frameless function or not.
1579 * core.c (core_open, core_close, core_xfer_memory): Move
1580 section table pointers and bfd* into the target_ops.
1581 (core_open): Allow errors in shared lib reading, etc.
1582 (core_files_info): Describe shared library sections.
1584 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
1585 exec_files_info, set_section_command): Move section table
1586 pointers and bfd* into the target_ops.
1587 (add_to_section_table): Add BFD to section table.
1589 * target.c (target_xfer_memory, target_info): Pass target to
1590 xfer_memory and target_info functions.
1593 * gdbcore.h: Move struct section_table.
1594 * target.h: New home of struct section_table.
1596 * solib.c (solib_add): New argument is the target_ops whose
1597 section list is to be added to, if any. Reallocate the
1598 sections in that target to add any that come from shared libs.
1599 (throughout) so_sections renamed to sections.
1600 (solib_xfer_memory): Deleted.
1601 * tm-sunos.h (SOLIB_ADD): Add target argument.
1602 (SOLIB_XFER_MEMORY): Delete.
1604 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1605 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
1606 from target_ops. It's the same on all targets. Add two section
1607 pointers to target_ops.
1609 * stack.c (find_relative_frame): Dump ancient algorithm for
1610 "down", just use handy "next" pointers.
1611 (frame_command): Don't error if there is no stack; let user
1614 * inflow.c (new_tty_prefork, new_tty): New prefork routine
1615 modifies static state in the parent process; new_tty itself
1616 runs in the child and modifies the child's file descriptors
1617 to match the saved static state.
1618 * infrun.c (child_create_inferior): Call new_tty_prefork,
1621 * infptrace.c (child_xfer_memory): Add ignored target arg.
1622 * remote-eb.c (eb_xfer_inferior_memory): ''
1623 * remote-nindy.c (nindy_xfer_inferior_memory): ''
1624 * remote-vx.c (vx_xfer_memory): ''
1625 * remote.c (remote_xfer_memory): ''. Rename from
1626 remote_xfer_inferior_memory.
1628 * main.c (main): Only try to attach "corefile" argument if
1629 it starts with a digit.
1631 * symfile.c (symbol_reloading): New "set/show" variable.
1632 (symbol_file_add): Shorten message about symbol reading.
1633 (add_symbol_file_command): Merge with add_syms_addr_command,
1634 since this should work on all targets now.
1635 (stop_whining): Default to zero, to shut up complaints
1636 about bad symbol tables on many systems.
1637 (free_named_symtabs): Just exit unless symbol_reloading.
1639 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
1640 and add comment explaining shared library screw.
1642 * source.c: #if defined => #ifdef.
1644 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1646 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
1648 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1650 * doc/rdl-apps.texinfo: provide default readline-appendix finder
1651 (doc/Makefile knows how to make one for local config)
1653 * Makefile.in: use doc/Makefile for doc targets
1655 * doc/Makefile: GDB documentation now has its own Makefile
1656 doc/refcard.tex: renamed from "gdbrc.tex"
1657 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
1658 doc/gdbint.texinfo: add markup in "Cleanups" chapter
1661 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1663 * values.c (baseclass_addr): When reading target memory, use the
1664 length of the basetype, not the upper type. We've only malloc'd
1665 enough space for the basetype, leading to errors in free().
1667 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
1668 ends up as a function specially, since we know the actual type of
1669 the pointed-to address. This (somewhat) fixes display of
1670 expressions that include misc_function_vector names. Try `cond 1
1671 !strcmp("a","b")' then `i b'.
1673 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
1674 The child can be proceeded from inside wait_for_inferior in
1675 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
1676 getting skipped in that case.
1678 * expprint.c (print_subexp): Use filtered output, since the
1679 subroutines we call use it, otherwise the output is horribly
1680 mangled, since output of wrappable stuff comes out late.
1682 * Makefile.in: Bump VERSION to 3.98.1
1684 * infrun.c (child_create_process): Use execlp to find the
1685 shell to exec our target program. This requires some fiddling
1686 with `environ' since there is no execlpe().
1688 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1690 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
1691 Minor rearrangement of refcard permits two new make targets--
1692 gdbrc.dvi DVI output for refcard, using CM fonts
1693 gdbrc.ps PostScript refcard, using PS fonts
1695 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1699 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
1700 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
1702 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1704 * doc/gdb.texinfo: last changes for release.
1705 Minor typo and formatting fixes; incorporated most fixes remaining from
1706 filed mail commenting on earlier drafts.
1708 Added warnings: pipes don't work in run command;
1709 conditions are converse of assertions;
1710 step over fn without debug info goes to next fn;
1711 vars may have "wrong" values near fn entrance, exit
1713 Added example from Kingston on printing repeated nonadjacent values
1715 Added explicit mention that in Emacs gdb mode C-c and C-z are like
1716 shell mode for signals
1718 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
1719 doesn't sound so much like its parent "Stopping and Continuing"; also
1720 moved entries on continue to top of section, so they don't get lost.
1722 Improved installation directions in appendix, added manual formatting
1725 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1727 * configure.in: Remove xm.h and tm.h even if we aren't linking
1728 new ones, so "./configure sun4; ./configure none" does the right
1729 thing. Assume that alldeps.mak and depend are already built in
1730 srcdir, and avoid running "make" (particularly "make depend",
1731 which involves "gcc") from inside configure. Build Makefile
1732 directly rather than building Makefile.conf first.
1733 * configure: Regenerate with above changes.
1734 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
1735 to 3.98. Revise gdb.tar.Z procedure to produce a file
1736 called gdb-$(VERSION).tar.Z but which unpacks into a
1737 directory called "gdb". Move non-source files out of
1738 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
1739 (depend): Don't try to do "gcc expread.y".
1740 (expread.o): Update dependencies by hand.
1742 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1745 Fixed a variety of small typos that prevented info from formatting
1746 cleanly; altered too-long heading for GPL Appendix, as discussed
1747 w/RMS; Changed date on cover to July 91.
1749 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1752 (1) Applied some fixes due to comments from Larry Breed (easier ones
1753 through chapsec 5.2)
1754 (2) Eliminated use of @footnote---had my doubts about it anyways, and
1755 it's broken in latest texinfo
1756 (3) Introduced *some* use of [] for optional arguments, where
1757 explanation is not simpler by listing cmd w arg and cmd w/out arg
1758 separately. Still not using @deffn.
1759 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
1760 couple of headings are too long. Need patches to texinfo or revision
1763 * Partial update to README (which still needs work for this
1764 release!): (1) use of configure corrected for new script,
1765 (2) "make gdb.dvi" and "make gdb.info" mentioned.
1767 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
1769 * symtab.c (lookup_symbol): Don't complain right off about
1770 no debug symbols; use the misc function vector first.
1771 (list_symbols): Use misc function vector to find symbols
1772 that don't have debug info, and print them.
1773 (find_pc_symtab): Temporarily avoid fatal() when psymtab
1774 PC range doesn't match symtab PC range, as it does on the
1775 MIPS because our symtab reading isn't perfect.
1777 * dbxread.c (dbx_symfile_read): Make warning about
1778 "no debug symbols" slightly nicer.
1780 * source.c (select_source_symtab): If "main" symbol exists,
1781 but decode_line_spec can't find line info, don't just return
1782 a zero; try other source symtabs or give an error.
1784 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
1785 their low addresses first, then rip through fixing high addrs.
1787 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
1788 <runene@ifi.uio.no>.
1789 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
1791 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1793 * Minor, mostly mechanical, cleanup of doc subdir for clean
1794 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
1795 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
1797 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
1799 Mostly MIPS and general symbol-reading fixups.
1801 * doc/gdbint.texinfo: Add documentation on symbol-reading
1804 * mipsread.c: Remove kludges around #include "ecoff.h".
1805 Remove redefinitions of a_magic, etc, no longer used.
1806 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
1807 Fix global overview comments to match symfile.c protocol.
1808 (mipscoff_new_init): Eliminate cur_hdr if we have one.
1809 (mipscoff_symfile_read): Eliminate unused code. Avoid
1810 sorting all the symtabs, when all we have read here is psymtabs.
1811 The symtabs are sorted as they are created anyway. Tell
1812 condense_misc_bunches whether we're mainline.
1813 (psymtab_to_symtab_1): Pass filename when recursing, to make
1814 stack trace more informative.
1815 (parse_partial_symbols): Assume cur_hdr as argument.
1816 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
1817 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
1818 the TYPE_NAME of char *, since that's done in symfile.c.
1819 (free_numargs, parse_symbol, add_symbol, add_block,
1820 shrink_linetable): Declare these fns void.
1821 (upgrade_type): Convert tree of if's to switch. Clean up
1822 bogus "off == 0" handling with a complaint. Avoid setting
1823 field bitpos and bitsize of array with lower and upper bounds.
1824 Check specified bitsize of elements against their actual type's
1825 bitsize, and complain if different. Complain about unknown
1827 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
1828 (psymtab_to_symtab_1): Print names of subsidiary files that
1829 are being read in. FIXME, we read far too many files. This code
1830 is not the problem, the problem is in parse_fdr where the psymtabs
1832 (cross_ref): Result should indicate that we used one aux entry
1833 normally, or two if we encountered a "next" entry. This used
1834 to leave the caller pointing at the wrong aux entry.
1835 (add_symbol): If overflowed cur_block, reallocate it larger,
1836 chase all pointers to it, and complain(), rather than clobber memory.
1837 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
1838 (new_field): Only allocate one field initially, not two.
1839 Pull ++ out of macro argument. Simplify.
1840 (_initialize_mipsread): Avoid initialization of importd
1841 global_psymbols and static_psymbols.
1843 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
1844 to properly set pst->symtab; avoid searching for it.
1845 (symfile_fns): Improve comments, add a FIXME.
1846 * dbxread.c: Update comments to reflect symfile protocol.
1847 (read_ofile_symtab, end_symtab): Return the symtab.
1848 (psymtab_to_symtab_1): Set pst->symtab.
1850 * coffread.c (coff_symfile_read): tell condense_misc_bunches
1851 whether we're mainline.
1853 * symfile.h (sym_fns): Remove unused sym_discard member.
1854 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
1856 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
1857 the environment variable is not.
1858 * infcmd.c (finish_command): Use filtered printfs.
1859 * cplus-dem.c: Add struct tags to a few unnamed structs.
1860 * valops.c (value_coerce_array): Improve comments.
1861 * valprint.c (type_print_varspec_suffix): Print array size only
1862 if greater than zero.
1863 * m88k-tdep.c: Shift some lines left by one space, that had
1864 apparently been trashed at some point.
1865 * TODO: More things to do, a few got done.
1867 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1869 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
1870 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
1872 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
1873 * expread.y, findvar.c, symmisc.c: Ditto.
1874 * printcmd.c (address_info): Update printed forms of LOC_
1875 symbols. Elim LOC_EXTERNAL.
1876 (print_frame_args): Keep track of param stack offsets before
1877 re-looking up to find the local register param is kept in.
1879 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
1880 Further integration of mipsread into gdb. Eliminate unused
1881 routines, duplicate declarations. Handle static symbols in
1882 psymtabs as well as external symbols. When reading symtabs,
1883 insert symbols into the correct block (global, static, or a local
1885 (read_mips_symtab, parse_partial_symbols): Don't pass useless
1887 (mipscoff_symfile_read): Don't call select_source_symtab.
1888 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
1889 rather than SYMBOL_VALUE.
1890 (parse_external): Comment clobbering of top_stack.
1891 (parse_partial_symbols): Update comments. Allocate and parse
1892 static symbols as well as external symbols. FIXME, enum values
1893 are not handled in this pass, but should be. Inline new_psymbol.
1894 Use SYMBOL_VALUE_ADDRESS.
1895 (psymtab_to_symtab_1): Read symbols into global static block
1896 by default (until enter some function's local block context).
1897 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
1898 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
1900 * source.c (select_source_symtab): Select a source symtab
1901 from either the symtabs or, failing that, the psymtabs.
1902 (list_command): Update error message.
1903 (forward_search_command, reverse_search_command): Use getc, not
1904 fgetc, for speed. FIXME, add comment about buffers that die if
1905 overrun by long line.
1907 * values.c (unpack_field_as_long, modify_field): Avoid shifting
1908 by an entire word, which is not portable, if we have a 32-bit
1909 field. (Code in dbxread.c already turns such bitfields, if
1910 aligned, into ordinary ints, but fixing this will help for other
1911 symbol formats and for future changes.)
1912 * core.c (core_open): Handle ANSI const brain death.
1913 * utils.c (vprintf): Fix varargs typo.
1915 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1917 * findvar.c (find_var_value): Handle &function better.
1918 * TODO: Document work needed on &fn and &array.
1919 * printcmd.c (print_address_symbolic): New arg is the prefix
1920 to print if a name is printed.
1921 (print_address_demangle): Honor "set print address" now.
1922 Use new arg above to improve spacing of output.
1923 * valprint.c (val_print): When printing function pointers,
1924 print symbolic form too.
1925 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
1927 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1929 * core.c (memory_error): Reword error msg to mislead less.
1931 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
1933 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
1934 parse_partial_symbols): Use newer BFD internals (external_filehdr
1935 and external_aouthdr), byte-swap the fields that we care about
1936 before using them, and make the file header data local to
1937 read_the_mips_symtab rather than global.
1939 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
1941 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
1942 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
1944 * main.c (command_line_input): Flush stdout and stderr
1945 before every call to readline. This reportedly fixes a bug
1946 that comes up in Sys V running emacs-gdb and/or xxgdb,
1947 when stdin/out are pipes or sockets.
1949 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1951 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
1952 Avoid declaring Makefile dependencies, because GNU Make stupidly
1953 tries to update it if we do.
1955 * coffread.c: Revise for minor changes to bfd internal coff
1958 * configure: If -template= is given a relative path, make it
1959 absolute before recurring in subdirectories.
1961 * configure, configure.in, Makefile.in: Install "configure" script
1962 as replacement for config.gdb.
1963 * config.gdb, Makefile.dist, Makefile.sdir: Remove
1964 * README: Update for configure, mostly. FIXME.
1966 * Add dec3100 as equivalent to littlemips. Indicate in all host &
1967 target config files that they are for the host. When the lines
1968 get copied into the Makefile, this makes it more obvious what's
1971 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1973 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
1974 tabs, which end up in the disassembler output inadvertently.
1976 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1978 Make it compile cleanly in an ANSI GCC2 environment.
1980 * blockframe.c: <stdio.h>
1981 * cplus-dem.c: free takes a void *, ifdef __STDC__
1982 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
1984 * defs.h (alloca): Avoid doing anything if alloca already def'd.
1985 * stddef.h, stdlib.h: Remove these files.
1986 * symtab.c: Avoid declaring qsort, close.
1987 * symfile.c: Avoid declaring close.
1988 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
1989 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
1991 Assorted other changes.
1992 * dbxread.c: include "libaout.h", not "liba.out.h".
1993 * printcmd.c (print_frame_args): Set recurse properly for
1994 indentation of struct and array parameters.
1995 * valops.c (value_cast): Allow cast to void.
1996 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
1997 single_step() in a target-independent fashion.
1998 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
1999 set up to be ready to continue. This makes us target independent.
2000 * infptrace.c (child_resume): Remove call to single_step; now
2001 can single step a SPARC target of any kind.
2003 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2005 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
2006 docn into separate sections---basically chapters, plus two loose
2007 pieces that can be configured to go in different places. This
2008 allows GNU m4 to preprocess the manual without coredumping.
2010 * Makefile.dist: tell TeX where to find texinfo.
2012 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2014 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
2015 the new target "rdl-apps.texinfo" which captures the Makefile
2016 variable that records where to find the Readline libraries.
2018 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
2020 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".

2023 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
2025 * README: Update for release 3.95.
2026 * config.gdb: Don't create readline dir in subdir builds.
2027 * main.c: Include with "..." form for non-system include files,
2028 so "gcc -MM" for "make depend" works.
2029 Include readline files with "...h" rather than <readline/...h>.
2030 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
2032 * coffread.c: Undo minor damage done by Rich Pixley. Use
2033 different internal and external representations of COFF
2034 data structures. Use new BFD routines for swapping them in and
2036 * symfile.c (free_named_symtabs): Avoid freeing file names that
2037 are null or empty. Old i960 tools seem to produce files that
2038 claim to have empty names, causing each successive file read
2039 to blow away the previous one.
2040 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
2041 Move deferred_stores to top of file, but don't separate its
2042 #define's from its variable. Add commentary.
2043 * Makefile.dist: Fix Rich damage; undo "configure" changes in
2044 favor of keeping the (working) config.gdb. Move readline
2047 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
2049 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
2051 * infptrace.c (fetch_registers): no result, since now void.
2052 * tconfig/news: target depends on m68k-tdep too.

2056 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
2059 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
2060 applied various small fixes due to or inspired by RMS comments
2062 * doc/gdb.texinfo: finished using all RMS comments, save those for
2063 appendices on readline and cmd history (which are in other source
2066 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2068 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
2069 chapter 9; (2) documented 'break' command's menu mode for
2070 overloaded names, in response to hgs problem report C++ p-31
2072 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2074 * doc/gdb.texinfo: (1) better introductory example; (2) more
2075 consistent use of @code, @samp, @file, @kbd throughout; small
2076 cleanups to first three nodes; (3) new "Contributors" node;
2077 (4) Appendix, Renamed Commands; (5) divert specialized startup
2078 instructions to "Targets" chapter for generic manuals, while
2079 leaving them up front for manuals specific to specialized
2080 environments; (6) apply fixes from RMS comments through chapter 4.
2082 * pretex.m4: modify explanatory text slightly (and redefine
2083 "regexp") to keep GNU m4 from complaining. (It still crashes
2084 later, but one step at a time...)
2086 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
2088 * readline/readline.c (update_line): Avoid dereferencing a pointer
2089 before comparing it to its bounds. Saber caught this.
2090 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
2091 and only set PC if tgetstr returned non-null. Saber caught this.
2093 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2095 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
2096 stuff for config manual) here where it counts; updated
2097 to use new subdir structure (gdb/doc/).
2099 * Makefile: generated from above via
2103 * gdbint.texinfo: added instructions on generating gdb.info* files
2104 locally for release. These are ordinary info
2105 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
2106 Makefile)---but due to use of texinfo 2, can't count on makeinfo
2107 to generate these, so we distribute them already formatted.
2109 * gdb.texinfo: included full Info node and menu crud (as generated
2110 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
2112 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
2113 put in comments-for-future gdb.info target (one day makeinfo will
2116 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2118 * gdb.texinfo: Updated to include new or old undocumented
2119 commands, at least the following (perhaps some others I forgot to
2120 record): info f, info float, info path, info program, info s, info
2121 set, info source, info terminal, info types, info user, set/show
2123 Also covered all recent GDB command renames for v4.
2125 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2127 * mipsread.c: Rather than keeping count of how many symtabs
2128 and psymtabs we have, for sorting purposes, count them when
2129 we need to sort. This fixes bug in rereading of symbol tables.
2131 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2133 * infcmd.c: renamed "info path" to "show paths"

2148 symtab.h, target.c, target.h: Lint.
2149 * core.c: setup and select frame after reading shared libs,
2150 else reading shared libs will clobber them. Lint.
2151 * utils.c (error): Force out any buffered wrap text.
2153 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2155 * remote.c: Remove decls of memory_insert_breakpoint
2156 and memory_remove_breakpoint, no longer used. (Suggestion of
2159 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
2160 to make it easier to interface to "configure"'d libraries.
2162 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
2164 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
2165 aliases for set/show print.

2677 core.c, exec.c, remote-eb.c, remote-nindy.c, remote-vx.c,
2678 remote-vx.68.c, inftarg.c, remote.c: Add doc field to target struct.

2708 command is add-symbols.
2709 * target.c (dummy_target): Permit add_syms_addr_command.
2711 Sat Apr 13 14:46:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2713 Permit symbols to be superseded when new symbol files have
2714 been read in, particularly for VxWorks.
2716 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
2717 to the main file, as well as to include files. Also, put global
2718 functions into the global psymtab, to make "i fun" work.
2719 (end_psymtab): Free named symtabs and psymtabs for a file, once a
2720 new psymtab for it has been read.
2721 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
2722 a file, once a new symtab has been read for it.
2723 * mipsread.c: FIXME. We need to do the same for MIPS, but it
2724 looks harder to determine the top-level block before it's been
2725 queued to the psymtab list.
2727 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
2728 If we have wiped out any old symbol tables, clean up at end of
2730 (symbol_file_command): Don't reference symfile_fns if it's zero.
2732 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
2733 defines for the blocks of a blockvector that contain global and
2734 file-static symbols and the first of the smaller scope contours.
2735 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
2736 decode_line_1, make_symbol_completion_list): Use the above.
2737 * coffread.c (end_symtab, patch_opaque_types): Ditto.
2738 * dbxread.c (end_symtab): Ditto.
2739 * expread.y (block): Ditto.
2740 * mipsread.c (throughout): Ditto.
2741 * symmisc.c (free_named_symtabs): Ditto.
2743 * symtab.c (list_symbols): Process the first symbol of the
2744 static psymbols list.
2745 (types_info): Restore this function from its untimely #if 0.
2746 It's not perfect, but it is better than nothing.
2747 (_initialize_symtab): Restore "info types".
2749 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2751 * m68k-stub.c: Remote stub for 680x0's, created from
2752 rem-m68k.shar (which is removed).
2753 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
2754 Remove RCS log stuff now that we use CVS and it blows our diffs.
2756 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2758 * symmisc.c (free_named_symtab): Make it work, in its current
2759 kludgy fashion. Change result to indicate if we blew away bkpts.
2760 * dbxread.c (end_symtab): Accumulate result from
2761 free_named_symtab and print warning if we blew user's state.
2762 * symfile.h: free_named_symtab now returns an int.
2764 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
2766 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
2767 is the first symbol read, even if not mainline.
2768 (dbx_psymtab_to_symtab): symfile might be zero, cope.
2769 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
2770 (set_section_command): New command ("section xxx yyy" -- should
2771 be renamed to "set section xxx yyy" FIXME) which sets the
2772 base address of a section of the exec file, overriding the
2773 virtual address that BFD reports.
2775 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2777 * exec.c: Add add_syms_addr_command to exec_ops, so you can
2778 load symbols at any address while examining an exec file.
2780 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
2782 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
2783 for printing the float info is host-dependent, not
2784 target-dependent. FIXME.
2785 * i386-pinsn.c: Move #includes to top, remove useless ones.
2786 * i386-tdep.c: Don't bother including <.../reg.h> since we
2787 don't use it (and it doesn't exist on host systems).
2789 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
2790 Convert negative numbers properly.
2791 (ieee_test): Make numbers really random; fix format arg.
2793 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
2794 * core.c (core_detach): Unpush core_ops, which might not be on
2795 top. We used to just pop the top, which broke things. Don't
2796 need dont_repeat() any more.
2797 (core_file_command): Psst! Don't repeat it.
2798 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
2799 * expprint.c (print_subexp): Avoid switch fallthru on
2800 BINOP_ASSIGN_MODIFY, so we can print += and such.
2801 * frame.h: Fix typo.
2802 * inflow.c (kill_command): After killing inferior, print our
2803 current frame in the core file, if we have one.
2804 (generic_mourn_inferior): When inferior dies, either select
2805 the current frame (in the new target, e.g. core file), or
2806 set both the current and selected frames to NULL.
2808 Changes from Peter Schauer.
2810 * infptrace.c: Avoid <sys/ptrace.h> on USG.
2812 * Make all file names fit in 14 characters (sigh and damn!):
2813 mv hp300hpux-xdep.c hp300ux-xdep.c
2814 mv symmetry-xdep.c symm-xdep.c
2815 mv symmetry-tdep.c symm-tdep.c
2816 mv convex-opcode.h convx-opcode.h
2817 mv tm-vxworks960.h tm-vx960.h
2818 mv tm-vxworks68.h tm-vx68.h
2819 mv Makefile.srcdir Makefile.sdir
2820 mv gdb-int.texinfo gdbint.texinfo
2821 mv remote-sa.m68k.shar rem-m68k.shar
2822 mv remote-multi.shar rem-multi.shar
2823 * Makefile.dist, README, config.gdb, convex-pinsn.c,
2824 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
2825 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
2828 * command.c (user_info_1, user_info): New command for listing
2829 the user-defined commands.
2831 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
2833 * dbxread.c (really_free_pendings): Clear file_symbols
2834 and global_symbols after freeing them; otherwise, running
2835 this function twice (if it appears twice on the cleanup
2836 chain), we try to free things twice.
2838 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
2839 based on text_addr (the address of text in core), not on addr (the
2840 offset between text in the .o file and in core). This change
2841 is from Peter Schauer.
2843 * main.c: Define ALL_CLEANUPS as a cast of zero.
2844 (return_to_top_level): Use it.
2845 (main): Do all cleanups after each command run as part
2846 of the gdb startup sequence. Also do all cleanups before
2847 entering the command loop, and every time we exit the command
2848 loop and reenter. Before, the cleanups from the startup sequence
2849 were being left undone until the first error!
2850 (command_loop): Rename do_nothing cleanup to command_loop_marker
2851 so we can see it easily when examining the cleanup chain.
2852 (init_signals): Add another do_nothing for signal handling.
2853 (quit_command): Only try to kill target if it has execution.
2854 Problems in the target stack got us into a state where
2855 inferior_pid was nonzero but none of the targets had execution.
2856 In this state you couldn't exit gdb.
2858 * dbxread.c: Two changes from Peter Schauer.
2859 (echo_command): Fflush output after an echo command.
2860 (show_history): Pass all args to cmd_show_list.
2862 * utils.c (init_malloc): Call mtrace to turn on tracing
2863 if the environment variable MALLOC_TRACE is set to a file name.
2864 * mtrace.c: Add source file which provides a log of every malloc,
2865 free, and realloc to a trace file.
2866 * mtrace.awk: Add source file which analyzes the trace file.
2867 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
2868 (VERSION): Roll to 3.94.3.
2870 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
2871 (check_duplicates): Don't bother with watchpoints.
2872 (set_raw_breakpoint): Comment about danger of this routine.
2873 (watch_command): Parse and eval all args before calling
2876 * solib.c (find_solib): Avoid error in referencing memory to
2877 see if any more shared libraries have been added. This is
2878 particularly useful if the target has terminated. Bug reported
2881 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
2882 in bringing up 3.94.2 on the Sun-3.
2884 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
2885 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
2886 expression (in scope) before reenabling watchpoint.
2887 * signame.c (init_sigs): Add missing declaration of i, fix
2888 sys_siglist declaration.
2889 * source.c (list_command): Fixed range computation to use
2891 * stack.c (backtrace_command): Do not allow command if target has
2892 no stack, print informative error message.
2893 * target.c (target_command): Do not write into command line
2894 because this fails if the target command is used in a user defined
2895 command. [This change was enhanced by gnu to support any-
2896 unique-prefix matching on target names.]
2897 * valops.c (value_struct_elt): Avoid infinite loop on an
2898 erroneous attempt to print the member of function (try p main.p).
2900 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
2902 * expread.y (name_no_typename): Avoid reduce/reduce errors
2903 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
2904 Since the GDB parser really doesn't use name_no_typename in a
2905 name-only context, the parser can't tell the diff between
2906 names and numbers here. Avoid allowing a name_no_typename
2907 to be a NAME_OR_*INT to resolve the conflict.
2909 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2911 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
2913 * valprint.c (val_print_fields): bitfield printing didn't handle
2914 byte order. Indirect through a few more fns to cope.
2916 * values.c (modify_field): also cope with byte order.
2918 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2920 Cleanup for release 3.94.2:
2922 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
2923 include files. Roll version to 3.94.2.
2925 * coffread.c (init_stringtab): Read length into unsigned char
2926 array before swapping; don't assume 32-bit longs.
2928 * target.c (target_info): Don't bother with get_sym_file, just use
2929 the symfile global variable.
2930 * symtab.h, symfile.c (get_sym_file): Delete it.
2932 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
2933 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
2934 (read_type): Replace one more error() with complain().
2936 * mipsread.c (parse_partial_symbols): Replace printf with complain.
2938 * i960-tdep.c: Fix copyright attribution.
2940 * config.gdb: Quote all backquotes in doublequotes. You can
2941 quote me on that. BSD 4.4 shell found this one.
2943 * infptrace.c (throughout): The third argument to ptrace is an
2946 * infrun.c (wait_for_inferior): When program has terminated, we
2947 have to call target_terminal_ours before we pop that target off
2948 the stack (e.g. before a call to target_kill or
2949 target_mourn_inferior). This fixes problem where a program
2950 terminates, then GDB stops for (tty output) and you have to type
2951 "fg" to the shell to resume it. FIXME: This code for what to
2952 do after termination really should be in normal_stop instead.
2954 * gdbcore.h (read_memory_check): Change declaration; it changed
2957 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
2958 4.4 prereleases, this avoids a bug in their sgtty compatability
2960 * remote.c: Use terminal.h rather than hand-rolling the same.
2962 * signame.c, signame.h (psignal): Arg is unsigned, not int.
2963 * utils.c (strsave, strstr): Fix arg types.
2964 * valprint.c (val_print): lint
2966 MIPS symbol table support from Per Bothner:
2968 * symfile.c (symtab_fns): Remove initializer table that needs to
2969 be hacked for each new symbol file format supported.
2970 (add_symtab_fns): New function, chains symbol table
2971 handlers into the global list.
2972 (symfile_init): Search this list.
2973 * symfile.h: Add next pointer, declare add_symtab_fns.
2974 * coffread.c (_initialize_coffread): Call add_symtab_fns.
2975 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
2977 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
2978 symbol *). Thus, we no longer need the hack to trash
2979 pst->filename. Good, since that hack confused code in symfile.c!
2981 (reorder_symtabs, destroy_all_symtabs): Removed static
2982 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
2983 Instead, the latter now uses a temporary array (stack-allocated
2984 from an obstack, and then freed).
2986 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
2987 haven't been set in the outermost stBlock of a procedure. This was
2988 a problem with f77 binaries on Ultrix 4.?.
2990 (new_symtab, new_symbol, new_type): Continue changing code to use
2991 obstacks more and otherwise conform to dbxread internal style.
2992 Made the free_code of symtabs be free_linetable (as in dbxread)
2993 instead of free_contents. This implies memory leaks when reading
2994 a new symbol table, until the conversion is finished. Did change
2995 (struct symbol) and (struct type) to be allocated on the
2996 symbol_obstack. Blocks and blockvectors are among the things
2999 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
3000 tested much, but it solved one problem (reported by Meissner), and
3001 cleans up some other things. The problem happened when an
3002 included file contains actual code (functions) and not just
3003 definitions. The mips coff is a little inconvenient there, since
3004 it may cause a procedure to be mapped to the wrong psymtab.
3006 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
3007 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
3008 this will need work for the new core paradigm.
3010 Opcode patches from the net:
3012 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
3013 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
3014 missing altogether - they are added here. From Bruce Bauman.
3015 * mips-opcode.h: The low mask for C0 instructions was too small.
3016 From Garrett Lau. I modified the fix to check the entire 32-bit
3019 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
3022 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3024 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
3026 * dbxread.c (read_type): Pointer subtraction (value_sub in
3027 valarith.c) sometimes failed because the types of the
3028 pointers being subtracted were not identical.
3029 These differed because dbxread.c was allocating pointer types
3030 using dbx_alloc_type+smash_to_pointer_type instead of
3031 lookup_pointer_type. I failed to find a justification for the
3032 former, so I changed it to use the latter. Similarly, I
3033 replaced smash_to_function_type by lookup_function_type,
3034 and smash_to_reference_type by lookup_reference_type.
3036 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
3037 _initialize_mipsread): corresponding changes.
3039 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
3041 * source.c (mod_path): Do tilde_expand on each component of the path,
3042 rather than on the (list of) paths as a whole.
3043 (print_source_lines): Set first_line_listed in addition to
3044 current_source_symtab and current_source_line. If the source was
3045 not findable, after a "dir" command to fix the problem,
3046 a "list" would get the wrong lines.
3048 While I was there... (gnu):
3050 * dbxread.c (read_type): Change error to complaint.
3052 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3054 First attempt at detailed understanding of symbol table memory alloc.
3056 * dbxread.c (dbx_symfile_read): Free our string table if we
3057 aren't the mainline. Free the "info" struct since we're done with
3059 (init_psymbol_list): Free any previously allocated psymbol lists.
3060 (): FIXME: Should realloc-down the psymbol lists when done reading
3061 the main symbol file?
3063 * symmisc.c (free_symtab): Free fullname field too.
3065 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
3066 (REGISTER_ADDR): Make result type unsigned int.
3068 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
3069 define REGEX must also define REGEX1 (its dependency).
3071 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
3073 * tconfig/i960: No longer works, points you at vxworks960 or
3076 * xgdb.c, XGDB-README: Remove file. Users can get the much
3078 * Makefile.dist: Remove all trace of xgdb.
3080 * breakpoint.c (breakpoint_1): Pass demangle arg to
3081 print_address_symbolic.
3082 (clear_breakpoints): Remove unused function.
3083 (breakpoint_re_set_one): Guts of breakpoint_re_set.
3084 (breakpoint_re_set): Use catch_errors to do them all anyway.
3086 * gdb-int.texinfo (Host versus Target): Add section on what is
3087 a "host" feature versus what is a "target" feature.
3089 * infcmd.c (path_command, path_info): Handle the PATH variable
3090 (object search path) as conveniently as the source search path.
3091 * environ.c (set_in_environ): Set some vars in GDB's environment,
3092 in addition to the child's. PATH, G960BASE, G960BIN for starters.
3093 * source.c (mod_path): New function, from guts of
3094 directory_command, modifies a path. Used by path_command.
3095 (directory_command): Call it.
3096 * defs.h (strsave): Declare.
3098 * utils.c (sevenbit_strings): Add new printing option.
3099 (printchar): Use it.
3100 (strsave): Provide this handy helper routine.
3101 (set_width_command): Rename set_screen_width_command.
3102 (_initialize_utils): "set screen-width" => "set width";
3103 "set screen-height" => "set height"; add sevenbit-strings.
3105 * infcmd.c (do_registers_info): Print floating point registers
3106 in raw hex as well as float format, regardless of whether it is
3107 a "virtual" convertible register.
3108 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
3109 regs as a double, just in case it's being used that way.
3110 * values.c (unpack_long): Comment on array/function coercion.
3111 (unpack_double): Argument is in target byte order now. For
3112 integer arguments, just call unpack_long and float the result.
3113 * m68k-tdep.c: include defs.h for "const" handling.
3114 * remote-nindy.c: Use ieee-float stuff.
3115 (nindy_fetch_registers): Unpack double regs to host double, then
3117 (nindy_store_registers): Pack extendeds to host double, flip
3118 around by misusing unpack_double, send as target double.
3120 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
3121 zero, as when stopped at the first instruction of a process.
3123 * blockframe.c: Fix filename in comment (param.h => tm.h).
3124 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
3125 * tm-68k.h: Fix typos.
3127 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
3129 Changes from a bringup on the DEC Vax under Ultrix 4.0.
3131 * coredep.c (fetch_core_registers): Pass end-address of register
3132 section to register_addr as expected. Don't call supply_register
3133 if we'd just pass it garbage.
3135 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
3137 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
3139 * target.c (push_target, target_info): Cast enums to int for < or
3142 * stack.c (print_frame_info): Identify source file & line
3143 even if we can't print it.
3145 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
3147 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
3149 Clean up IEEE floating point support.
3151 * ieee-float.h: New file.
3152 * ieee-float.c: Write real routines to convert between host
3153 doubles and various target IEEE extendeds.
3154 * m68k-xdep.c: Eliminate assembler code for extended floats.
3155 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
3156 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
3157 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
3158 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
3159 double_to_ieee_extended.
3160 * i960-tdep.c: Define ext_format_i960.
3161 * m68k-tdep.c: Define ext_format_68881.
3162 * sparc-tdep.c: Define ext_format_sparc, though unused.
3163 * Makefile.dist (HFILES): Add ieee-float.h.
3164 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
3167 Obsolete the "coffstrip" program in favor of using BFD's strip.
3169 * nindy-share/coffstrip.c: Remove file.
3170 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
3171 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
3172 * tconfig/nindy960: Remove reference to coffstrip.o.
3174 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
3176 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3178 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
3179 * dbxread.c: Remove static symfile_bfd.
3180 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
3182 * inftarg.c (child_detach): Pop the child_ops vector if the
3183 detach is successful.
3184 * remote-nindy.c (nindy_create_inferior): Don't push a new
3185 nindy_ops since nindy uses the same one for execution and memory
3187 * core.c (core_ops): Use child_attach and child_create_inferior
3188 rather than default attach and create_inferior functions.
3190 Handle floating point registers in core files.
3192 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
3193 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
3194 This version untested since BFD doesn't yet support sun3 core
3196 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
3197 conventions. Fix comments and style. This version has not
3198 been compiled yet, since we have no HP inhouse.
3199 * core.c (get_core_registers): Look for two sections, ".reg"
3200 and ".reg2", and pass both to fetch_core_registers sequentially.
3202 Revise directory path yet again.
3204 * source.c (forget_cached_source_info): Not static any more.
3205 (init_source_path): New default source path is "$cdir:$cwd".
3206 (dir_command): Handle variable arguments ($cdir, $cwd).
3207 (source_info): Print "Compilation directory" rather than
3208 "Originally compiled in" to remind people of $cdir.
3209 (openp): If the path contains $cwd, use current directory.
3210 (open_source_file): If compilation directory is known, replace
3211 first $cdir in path with the compilation directory.
3212 (print_source_lines): Even if we can't print the lines, set the
3213 current symtab and line for future commands like "info source" or
3214 "breakpoint". Also, error message now contains the file name,
3215 line number, and file access error message.
3216 (_initialize_source): Fix help text to describe changes.
3217 * main.c (cd_command): Forget cached source info when we chdir.
3218 * utils.c (strstr): Add simple implementation.
3220 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
3222 * coffread.c (read_one_sym, init_linetable, init_stringtab):
3223 Byte-swap COFF symbol tables if necessary when reading them in.
3224 Use complain() to replace error message in one spot. Needs
3225 corresponding change in bfd/coff-code.h to make some symbol
3226 swapping routines non-static.
3228 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3230 Merge changes from Eirik Fuller, for UTek.
3232 * defs.h (errno): Add declaration.
3233 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
3234 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
3235 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
3236 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
3237 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
3238 declarations of errno.
3240 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
3242 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
3243 <rpc/rpc.h> and <rpc/types.h>.
3245 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
3247 * i960-tdep.c (examine_prologue): Add new argument limit,
3248 which stops the scan at the end of the prologue, or at the PC.
3249 This fixes a problem where it walks down into the code for the
3250 user's statements if that code looks like function prologues.
3251 Mark Fox and I have been bouncing this code back and forth, making
3252 small changes to it. Callers changed to match.
3254 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
3256 Cleanup for gdb-3.94 release final:
3258 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
3259 the .c files from vx-share and nindy-share, from the various
3260 macros, since they are not found via ALLDEPFILES.
3261 (SFILES): Add tm-i960.h.
3262 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
3263 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
3265 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
3266 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
3268 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
3270 * am29k-tdep.c: Add contribution line.
3271 (examine_prologue): Cache information about function prologues in
3272 the misc-function-vector to avoid lots of references over the
3273 serial line while examining instructions.
3275 * core.c (core_close): New function made from cleanup_core.
3277 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
3278 remote-vx.c, remote.c, target.c, target.h,
3279 Update target_ops vector to add attach, close, and load entries.
3280 Use add_syms_addr_command, not add_file_addr_command, for
3281 add_file. Break out close routine from existing code.
3283 * dbxread.c (really_free_pendings): Don't free pending_blocks;
3284 they are in an obstack.
3285 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
3287 (define_symbol): Add symbol type parameter; change callers;
3288 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
3289 it to influence the symbol class on the i960.
3290 (define_symbol): Swap LOC_CONST's into target byte order.
3292 * exec.c (exec_close): New function.
3293 (exec_file_command): Call it.
3295 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
3296 Fix byte order of frame pointer.
3297 (read_var_value): Result of 0 if var's value can't be found,
3298 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
3299 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
3300 (locate_var_value): Use read_var_value and use its lazy address
3301 as the location of the var's value. Lint.
3303 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
3306 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
3307 obsolete Intel versions in favor of vxgdb versions.
3308 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
3309 code dealing with byte order of values, which Intel did in host byte
3310 order rather than gdb-4's target byte order.
3311 (i960_frame_chain_valid): Move to nindy-tdep.c.
3312 (examine_prologue, skip_prologue, frame_find_saved_regs,
3313 frame_args_address, leafproc_return, saved_pc_after_call,
3314 pop_frame): Add vxgdb versions from Mark Fox.
3315 (examine_prologue, frame_struct_result_address): Add code
3316 to deal with the saved value of G13 (struct return address
3318 (frame_args_address): Modify Mark's version to prefer the
3319 saved value over the current value in the topmost frame.
3320 Cache result in the frame info to avoid performance hair in
3322 (print_fault): Add gdb960 code for printing faults.
3323 (_initialize_i960): Actually call check_host.
3325 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
3326 add stub routines. FIXME, these currently just return zero!
3328 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
3329 (attach_command): Call target_attach, not target_open, now.
3331 * infrun.c (normal_stop): Make global, not static, for vx_attach.
3332 (child_attach): Rename from child_open.
3333 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
3334 don't confuse it with a zero step_resume_break_address.
3336 * inftarg.c (child_detach): Eliminate inferior_pid test.
3337 (child_files_info): Clean up message a bit.
3338 (child_ops): Use child_attach, not child_open, to attach.
3340 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
3341 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
3342 findvar.c to here, since it depends on the contents of the
3343 shadow_contents of breakpoints, but keep if #if 0 since it is
3346 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
3349 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
3350 (ptype_command, display_command): Eliminate have_inferior_p and
3351 have_core_file_p in favor of target_has_stack or
3352 target_has_execution.
3353 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
3354 code for actually finding the values of arguments, though we still
3355 keep track of the maximum stack offset for use in printing unnamed
3356 arguments. Handle missing FRAME_ARGS_ADDRESS.
3358 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
3359 (struct nindy_regs): Define registers passed to/from nindy.
3360 (nindy_fetch_registers, nindy_store-registers): Translate between
3361 nindy and GDB formats for the registers.
3362 (dcache_init): Statically allocate the cache, since it was being
3363 allocated by a malloc that was never freed anyway.
3364 (nindy_create_inferior): Error, not core dump, if no exec file.
3365 (nindy_before_main_loop): Use target_load, not target_add_file.
3367 * remote-vx.c (net_load): Specify large timeout for load
3368 requests. Allow user to break out with INTERRUPT.
3369 (net_break): Remove useless code, clean up. Change callers.
3370 (parse-args, skip_white_space, find_white_space): Clean up arg
3371 parsing to cope with quoted strings.
3372 (net_wait, net_quit): Never call error, just return status.
3373 (vx_read_register, vx_write_register): Cleanup status checking.
3374 #ifdef the code based on which CPU we are using (960 or 68k),
3375 FIXME, this should be completely general but it isn't yet.
3376 (vx_xfer_memory, vx_resume): Cleanup status checking.
3377 (vx_run_files_info): Improve message.
3378 (vx_load_command): Renamed from vx_add_file_command. Allow load
3380 (net_ptrace): Remove unused routine.
3381 (vx_wait): Adopt code from vxgdb960 to cope with broken
3382 connections to target machine and prompt to disconnect. Remove
3383 debug printouts. Map some EVENT_'s to SIGnals.
3384 (add_symbol_stub, vx_open): Print names of object files we found,
3385 and "ok" if we read their symbols OK. Clarify output in general.
3386 (vx_attach, vx_detach, vx_kill): Add these commands.
3387 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
3388 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
3389 "info files" output, and create_inferior, since we already have
3392 * stack.c (frame_info): Replace Frame_unknown with 0.
3393 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
3394 (return_command): Pop until the PC matches as well as the FP,
3395 so it works even if the FP is shared with another function,
3396 as in "frameless" or "leaf" procedures.
3398 * symfile.c (load_command): renamed from add_file_target_command.
3399 (add_syms_addr_command): renamed from add_file_addr_command.
3400 (add_syms_command): Stub to call target_add_syms.
3401 (_initialize_symfile): Change command names and descriptions,
3402 add-file => add-syms, and load from alias to its own command.
3404 * target.c (kill_or_be_killed, maybe_kill_then_attach,
3405 maybe_kill_then_create_inferior): Default for attempts to start
3406 a process, if one is already running, is to ask about killing
3407 it and retry if yes.
3408 (upstack_create_inferior): #if-0 it, strata obsolete it.
3409 (push_target, unpush_target, pop_target): to_close() a target
3410 before unstacking it.
3411 (target_info): Renamed from target_files_info.
3412 (_initialize_targets): Rename "i files" as "i target", accessible
3415 * target.h: Improve comments about the target_ vectored routines.
3417 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
3418 Convert commenting style to standard GNU style.
3419 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
3420 (SKIP_PROLOGUE): No longer a no-op.
3421 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
3422 (*_REGNUM): Sort register numbers.
3423 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
3424 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
3425 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
3426 are now 10 byte extendeds, not 8 byte doubles.
3427 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
3428 for nindy versus vxworks targets. FIXME, this should possibly go
3429 in the target vector.
3430 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
3431 frame_saved_regs and arg pointer with each frame.
3432 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
3433 (FRAME_ARGS_ADDRESS): Use cached result.
3434 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
3435 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
3436 (PRINT_RAMDON_SIGNAL): Call print_fault.
3437 (POP_FRAME): Now works.
3439 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
3440 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
3441 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
3442 (ADDITIONAL_OPTION_HANDLER): use target_load, not
3445 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
3446 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
3448 * valarith.c (value_subscripted_rvalue): Avoid handling
3449 floats and doubles specially; it gave alignment errors. Lint.
3451 * valops.c (value_of_variable, value_of_this): Error if unknown
3454 * valprint.c (print_floating): Bcopy rather than pointer-deref,
3455 to avoid alignment problems.
3456 (value_print): Handle unknown value address.
3457 (cplus_val_print): Two args are ignored; remove them. Change caller.
3458 (val_print): Use unpack_long rather than pointer-deref.
3461 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
3462 to avoid alignment problems.
3463 (value_being_returned): Error if return value unknown.
3464 (set_return_value): Add bogosity warning, FIXME. *
3466 * TODO: A woman's work is never done.
3468 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
3469 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
3470 Add ieee-float.o to OBS.
3471 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
3472 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
3473 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
3475 Changes to generalize the VxWorks RPC protocol slightly, to handle
3476 i960 as well as 68000.
3478 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
3479 * vx-share/reg.h: Produce i960 regs #ifdef I80960
3480 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
3481 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
3482 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
3483 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
3484 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
3485 so they will move in target byte order rather than network
3486 byte order (happens to be the same).
3488 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
3490 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
3492 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
3495 Add contribution lines to various files, showing where they
3498 * breakpoint.c (break_insn, check_break_insn_size,
3499 read_memory_nobpt): Remove to mem-break.c.
3501 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
3504 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
3505 entry has bad register number. This change is not
3506 tested in this release, FIXME.
3508 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
3511 * value.h: Force value's contents field to be aligned to hold
3512 at least a double or a long long (if supported). This avoids
3513 doing bcopy's in and out of the contents field.
3515 (step_1): Avoid coredump under obscure circumstances when we
3518 * symtab.h (misc_info): Add field to misc function vector for
3519 any kind of cached information the target code desires. AMD
3520 29000 uses this to avoid repeating examine_function_prologue's.
3522 * coffread.c: Lint. Remove static symfile, read_section_header.
3523 core.c (have_core_file_p): Lint: remove.
3524 expprint.c (print_subexp): Lint.
3525 infptrace.c, valops.c, valprint.c: lint.
3527 Roll in changes from vxgdb-5.0.1:
3529 * symtab.h: Comment byte order of each address class. Add
3530 LOC_LOCAL_ARG for frame-relative args (960).
3531 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
3532 symtab.c, symmisc.c: ditto.
3534 * infrun.c (init_wait_for_inferior): Clear stop_signal.
3536 * remote.c (remote_resume): Error if resume with a signal.
3538 * symfile.c (prim_record_misc_function): Clear misc_info.
3539 (fill_in_vptr_fieldno): Check stub type of arg.
3541 * valops.c (value_cast): Avoid looking up names of types whose
3542 name we don't know, to prevent coredump. Sun CC produces typedef
3543 rtx and the name of *rtx is zero...
3545 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3547 Roll in changes from final AMD 29000 port (Tiemann).
3549 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
3550 for ../include/a.out.encap.h. This might not work now that BFD
3551 is separately compiled. Instead, BFD support for encap will have
3552 to translate machine type 29k into the right COFF_MAGIC.
3554 * infcmd.c: Remove references to inferior_pid that aren't used
3555 in actual ptrace calls; use target_has_execution, etc.
3556 (have_inferior_p): Remove function.
3557 (program_info): Print target info rather than "process number";
3558 avoid gratuitous messages unless from_tty.
3559 (run_stack_dummy, finish_command): Set proceed_to_finish.
3560 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
3561 main.c: Lint. Lose have_inferior_p().
3562 inferior.h (have_inferior_p): Remove, lint.
3563 (proceed_to_finish): Add flag to ask that all regs be saved
3564 by normal_stop, for the few commands that need it, speeding up
3565 serial I/O. Add comments to stop_registers.
3567 * remote-eb.c: Remove newline from breakpoint message we grep
3568 for. Never time out when running the user program.
3572 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3574 Roll in changes from vxgdb-5.0.1:
3576 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
3577 symbol in its raw form, we are processing an unlinked ".o" file.
3578 See if the target environment has assigned it an address, using
3579 target_lookup_symbol (VxWorks does), and enter it into the symtab
3582 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
3583 68k versions for a simpler version that assumes zero FP at bottom.
3584 Fixes bug of truncated stack reports.
3586 * target.h (target_lookup_symbol): Define this routine's args
3587 and result, finally.
3589 * target.c (nosymbol): Default routine for target_lookup_symbol.
3590 (target_default): Default lookup_symbol and call_function too.
3591 (files_info): Only print has_all_memory warning if a non-dummy
3594 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
3595 vx_convert_from_virtual): If target does not have floating point,
3596 zero register "values", and avoid doing cross-net conversions.
3597 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
3598 (vx_open): Rearrange code that attaches to target and reads
3599 symbols for all loaded modules, to work if some of the modules
3600 are not accessible. Add symbol_stub() and add_symbol_stub()
3601 as callbacks from catch_errors(). Allow connect attempt to be
3602 interrupted painlessly with ^C (FIXME, there are still some bugs
3603 if the interrupt happens during symbol reading.). Print
3604 final message with puts_filtered, since symbol messages are
3609 * main.c (catch_errors): Only print errstring if non-null.
3610 (command_loop): Avoid an ioctl per command to test ISATTY.
3612 * remote-vx.c (net_load): make static; avoid sophomoric msg.
3613 (vx_xfer_memory): Return correct result!
3614 (vx_files_info): Indicate whether target has float or not.
3615 (vx_lookup_symbol): Complain, not error, if target gone.
3616 (vx_open): Print "Connected" msg before disabling immediate-quit.
3617 [FIXME: lookup_symbol and vx_open changes need testing.]
3619 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
3620 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
3621 contributor lines and update copyrights to 1991.
3623 Changes from an attempted H-PUX host port:
3625 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
3626 defines PT_ATTACH and PT_DETACH but not PT_KILL.
3627 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
3628 * remote-vx.c: include <sys/time.h> for HPUX.
3629 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
3630 "core_file_command" routine to BFD regime. May not work yet.
3632 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
3634 * xgdb.c: Replace X10 version with some VJ version.
3635 (FIXME: Its copyright assignment is not on record.)
3636 * xgdb.c: Update include files to X11R4 (Xaw crud).
3637 (xgdb_display_source, create_text_widget): fix call to
3638 get_filename_and_charpos. Rewack source window stuff for X11R4
3639 (gleaned from include files, and "nm's" of binary libraries, since
3640 I had no doc available).
3641 (append_selection, append_selection_word): Disable with FIXME
3642 since R4 changed interface here.
3643 (create_buttons): Add back the old set of buttons.
3644 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
3646 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
3647 Roll VERSION to 3.94 (not yet final though).
3649 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3651 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
3652 obstack_int_grow, obstack_int_grow_fast): Eliminate
3653 cast on left of assignment, which gives MIPS cc fits and is
3656 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
3657 F_ALIAS. Use printf, not fprintf, when not passing a file
3659 (compare_opcodes): Check that identical instructions have
3660 identical opcodes, complain otherwise.
3662 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
3663 was reported by Roland McGrath.
3664 (unimp): Only match if exactly zero instruction. (Roland)
3665 (branches and traps): Generate all variations of these
3666 instructions with macros, based on a single call that defines
3667 each condition name and its binary representation.
3668 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
3670 * valprint.c (val_print_fields): Take, and use, format parameter.
3671 This means that "p/x struct" again prints the elements in the
3672 desired format. Changed callers.
3674 * stack.c (frame_info): Use filtered output, and indicate wrap
3675 points. Remove kludgy formatting designed to avoid line wrap.
3677 * utils.c (wrap_here): If the line is already full (because
3678 we had printed a long indent or long wrapped string), do an
3679 immediate newline-and-indent.
3681 * m68k-pinsn.c (print_insn_arg): Bugfix from
3682 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
3683 instruction is incorrectly disassembled as bkpt #8.
3685 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
3686 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
3687 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
3688 and then will dump core (sometimes). I traced it back to an
3689 uninitialized symfile_name in psymtab_to_symtab.
3690 (const_vol_complaint): Add quotes to message.
3691 (define_symbol): Only believe line number if gcc_compiled.
3692 Avoid allocating symbol if we will not return it.
3694 Add target strata support so that newly established targets go
3695 into their right place in the target stack (e.g. a new exec file
3696 doesn't wipe out the ability to access the running process).
3698 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
3699 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
3700 and initialize it properly in all the targets.
3702 * target.h: Document strata. Change return type of push_target.
3704 * target.c (nomemory): new function for dummy memory access.
3705 (tcomplain): Rename complain, now also used in symfile.c.
3706 (push_target): Push targets within strata. New return value shows
3707 whether new target is on top of stack or not. Always keep dummy
3709 (target_files_info): Ignore dummy target.
3711 * core.c (core_open): Warn user, and skip accessing file, if the
3712 core target is not the topmost target in the stack.
3713 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
3716 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
3717 target_ops, it doesn't belong there since we have no regs there.
3718 Change name of target from machine => memory to clarify.
3720 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
3722 * Freeze version 3.93 for release.
3724 * Makefile.dist: Handle vx-share and nindy-share subdirs
3725 properly when building gdb.tar.Z.
3727 * symtab.c: lint; add no_symtab_msg to consolidate the messages
3728 printed in various places, so I could change just one copy.
3730 * dbxread.c, coffread.c: Change references to bfd->iostream
3731 to cast to FILE *, now that BFD avoids needing types defined
3732 in other header files.
3734 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3736 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
3737 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
3738 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
3739 (actually gcc -Wall).
3741 * dbxread.c: Remove first_global_sym, last_global_sym, since
3742 they are never referenced.
3744 * defs.h (baud_rate): Declare.
3745 main.c: Define it, and add the -b option to set it.
3747 * gdb-int.texinfo: Add text on how to define a new host or target
3748 architecture, prompted by Per Bothner's questions about MIPS
3751 * gdb.texinfo: Document "complaints". Change doc of -q since
3752 gdb no longer prints the copyright and blurb if you specify a file
3753 name to be debugged (just like Emacs). Add doc for Nindy-specific
3754 command line flags for specifying target serial port and such.
3755 Update copyright to 1991.
3757 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
3758 has taken over for us the job of ripping up executable files. The
3759 crud caused Per Bothner's port to not compile.
3761 * infrun.c (normal_stop): Avoid printing "Program exited
3762 normally" if we are in batch mode. This allows a GDB which
3763 executes a program on a target system, to behave like a Unix
3764 command (input from stdin, output to stdout, no extraneous
3767 * main.c (main): Allow additional machine-dependent command line
3768 options to be specified with the ADDITIONAL_OPTIONS,
3769 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
3770 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
3771 processing to occur just before the main loop with
3772 BEFORE_MAIN_LOOP_HOOK.
3773 (main): If a "core file" argument is specified, and it is not a
3774 core file, try it as a process ID to attach.
3775 (symbol_completion_function): Attempt to cope with
3776 "show screen-" TAB, not very successfully. This needs more work,
3778 (batch_file): New function, returns whether we are reading
3779 commands from an interactive tty on stdin, or from somewhere else.
3780 Called by normal_stop since it doesn't get from_tty passed down
3781 to it like many commands do.
3783 * remote-nindy.c: Handle command line options for nindy
3785 (nindy_before_main_loop): Prompt user for tty name if they
3786 don't specify it before getting to the interactive command loop.
3788 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
3789 and -r command line options. Also add hook before main loop
3790 to make it easy to specify a tty.
3792 * TODO: More things to do, one done.
3794 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
3796 * dbxread.c: Make complaint() calls pass pointer, not struct.
3797 Add complaints about badly formatted C++ type information
3798 (const/volatile indicator, and parse errors resulting in
3799 error_type). Fix C++ virtual member fn comment.
3800 (read_struct_type): Avoid bumping pointer if we got a parse
3801 error; this prevents our walking beyond the end of a string.
3802 Terminate loop on null char as well as semicolon.
3803 (process_one_symbol): Fix the LBRAC fix so that it uses the
3804 last previous SLINE, FUN, or SO record's PC address. C++ debug
3805 symbols did not have SLINE records in a useful order compared
3806 to the LBRAC records.
3807 (define_symbol): Handle "catch" records.
3809 * symtab.c (check_stub_type): Added new complain
3810 `stub_noname_complain' and added a consistency check to
3811 keep the debugger from crashing when finishing from an
3812 exception frame. A real fix will be needed later.
3814 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
3816 * infcmd.c (attach_command): Make global.
3818 * Makefile.dist (REMOTE_OBS): Make these compile by default,
3819 but make them easy to comment out. Perhaps later they should
3820 be enabled by what CPU you configure for? FIXME.
3821 (VERSION): Roll to 3.93.
3822 (pinsn.o): Remove rule for obsolete file.
3823 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
3825 Run down a problem that manifested by printing the wrong function
3826 name in stack traces of read_ofile_symtab. Turned out that the
3827 problem was the SunOS 4.1.1 (and previous) C compiler outputs
3828 the LBRAC symbol with an address in the *data* segment, which
3829 blew our binary search through the blocks.
3831 * dbxread.c: Use the complain() facility consistently to bitch
3832 about problems in the symbol file we are reading.
3833 (finish_block): Add code to check the nesting of the blocks;
3834 complain and Procrust them to fit if wrong.
3835 (make_blockvector): Check the order of the blocks, complain
3836 [but don't cope] if wrong.
3837 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
3838 symbols to be sure their PC value is greater than the last SLINE
3839 (line number) symbol we've seen, complaining and adopting the
3840 SLINE PC value if wrong.
3842 * symfile.h (struct complaint, complaint_root, complain,
3843 clear_complaints): Add.
3844 * symfile.c (complain, complaint_root, clear_complaints): Add
3845 facility to deal with non-fatal complaints and to regularize their
3847 (symbol_file_add): Clear complaint counters to allow new complaints.
3848 (initialize_symfile): Add 'set complaints' and 'show complaints'.
3850 * dbxread.c (dbx_symfile_read): Remember the address and size
3851 of the string table for the main symbol file, so we won't read it
3853 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
3854 to avoid reading the string table yet again. Lint.
3855 (throughout): Improve filtered output, including word wrap.
3856 (read_range_type): Improve Bothner's fix to handle other types too.
3858 * utils.c: Improve line wrap implementation. Handle unlimited
3859 width by making chars_per_line unsigned.
3860 (puts_filtered): New, easy, function.
3862 * defs.h (puts_filtered): add.
3864 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
3865 call the identical sort_symtab_syms() in symfile.c instead.
3867 * expread.y: Suggest the `file' command rather than `symbol-file'.
3869 * command.h (enum var_types): Add zinteger for seroable
3871 * command.c (do_setshow_command): Handle var_zinteger. Restructure
3872 nested if's into a switch.
3874 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
3875 we did not stop because of a breakpoint (it must have been for
3876 some other reason, like a "stepi"), so don't print anything.
3878 * symtab.c: Include <sys/types.h> all the time. Now that BFD
3879 doesn't include <sys/types.h>, old SunOS's require it for
3882 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
3884 A test port of gdb-3.92.6 to the Sony NEWS.
3887 Don't normally link in remote- or vx stuff.
3888 Some of it doesn't compile, and it wastes space for 99% of the users.
3889 Remove reference to no-longer-used HAVE_VPRINTF.
3890 Fixed BFD_DEP typo to BFD_DIR.
3892 Fix cast in arg to bfd_h_getlong.
3893 Make char *prefix be const.
3894 Fix how certain range types are mapped into builtin unsigned int types.
3896 Remove 2 #includes. They cause errors (on Sony, at least),
3897 and aren't needed (they wern't in earlier versions).
3899 print_address_symbolic should never demangle labels
3900 (since it prints *assembler-level* labels).
3902 [This was superseded by the change to printcmd below.]
3905 Add some "volatile" return types to avoid warnings.
3906 If MISSING_VPRINTF add vprintf function and not just macro
3907 (since vprintf is used in printcmd.c).
3909 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
3910 (The latter isn't grokked by some PCC-based compilers.)
3912 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
3914 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
3915 * nindy-share/coffstrip.c
3916 Added some forward declarations (otherwise, gcc complains
3917 about implicit extern redefined as static).
3919 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
3921 Changes inspired by Per Bothner:
3922 * printcmd.c (print_address_symbolic): Take additional parameter
3923 specifying whether to demangle.
3924 (print_address): Pass in asm_demangle to control demangling.
3925 (print_address_demangle): New fn, takes explicit arg to control
3927 * utils.c: Add new vars demangle and asm_demangle, and let them
3929 (fputs_demangled): If !demangle, just print the argument.
3930 (fprint_symbol): If !demangle, just print raw symbol.
3931 * valprint.c (val_print): Call print_address_demangle rather than
3932 print_address, to cause demangling to depend on the global
3933 rather than assembler-level demangling setting.
3934 * WHATS.NEW, gdb.texinfo: Document.
3936 * main.c (show_command): Show all settings if no arg.
3937 (initialize_main): Make "info set" the same as naked "show".
3938 * command.c (cmd_show_list): Handle prefix commands in the
3939 list, and print the name of the setting as well as its English
3940 description and value.
3942 Allow gdb functions to specify where a line should wrap if it
3943 exceeds the size of a terminal line. Use it to make the output
3945 * utils.c (set_screen_width_command): New fn, mallocs a buffer
3946 of the right size when screen width changes.
3947 (set_screensize_command, screensize_info): Remove #if 0'd fns.
3948 (wrap_here): New fn, indicates a point in the output where we
3949 should wrap the line rather than just letting it overflow at a
3951 (fputs_filtered): Implement wrapping.
3952 (n_spaces): New fn, returns a pointer to N spaces.
3953 (print_spaces_filtered): Use n_spaces.
3954 * defs.h (n_spaces): Declare.
3955 * stack.c (print_frame_info): Wrap with 4-space indent after
3956 fn name and before filename and line number.
3957 * printcmd.c (print_frame_args): Wrap with 4-space indent
3958 before each argument name is printed.
3959 * valprint.c (value_print): Wrap with no indentation before
3961 (val_print_fields): Wrap with indentation relative to nesting
3962 level before each field name.
3963 (val_print): Wrap with nesting indentation before array elements.
3964 * command.c (do_setshow_command): Avoid extra newlines,
3965 wrap with 4-space indent around values printed, end with period.
3966 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
3968 * breakpoint.c (breakpoint_1): Implement addressprint for
3969 "info breakpoints" display. Change file name and line number
3970 format to " at file:nnn" rather than " (file line nnn)".
3971 * gdb.texinfo: Document.
3974 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3976 Frozen for gdb-3.92.6 release.
3978 README, WHATS.NEW: Update for 3.92.6 release.
3980 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
3981 coffread.o from configs since it is now built by default.
3982 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
3983 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
3984 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
3985 from configs since it is now built by default.
3987 Makefile.dist: Update for release 3.92.6. Handle files that
3988 have been moved to ../include, ../getopt, or ../bfd. Add
3989 saber.suppress and tests directory. Add config.status to
3990 the release (it will say "none").
3992 coredep.c: Minor formatting fixes.
3994 These changes were made in early December but only checked in now:
3995 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
3996 nindy-share/nindy.c: lint
3997 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
3998 register values coming back from the target; we store values
3999 in target byte order everywhere.
4001 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
4003 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
4005 * valprint.c (cplus_val_print, val_print_fields): New functions,
4006 which print C++ objects. They conspire to avoid printing a
4007 virtual base class more than once, following all the twists and
4008 turns of C++ virtual base rules.
4009 (val_print): Call the above rather than do it by hand.
4011 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
4012 symbol file, not for added files like shared libs. This really
4013 needs to be generalized to a timestamp per file.
4015 * core.c (cleanup_core): Avoid coredump if no core file.
4017 * config.gdb: Accept -host or -target in place of +host or
4020 * coffread.c (find_linenos): Avoid desupported BFD interface
4021 to line numbers. We still read them manually rather than using
4022 BFD's "generic" features.
4024 * gdbrc.tex, threecol.tex: Add GDB reference card and its
4026 Makefile.dist: Add refcard to OTHERS list for creating tar files.
4028 * Makefile.dist: Eliminate use of $< in explicit targets.
4030 * readline/Makefile: Use $< rather than $*.c, which does not
4031 include the VPATH in GNU Make.
4033 * tconfig/i960-bout, tconfig/i960-coff: These are identical
4034 copies of tconfig/i960, added for global configuration
4035 compatability. All i960 versions can read both coff and b.out.
4037 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
4038 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
4041 * TODO: Think of more things to do.
4043 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
4045 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
4046 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
4047 64-bit float conversion.
4049 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
4050 equivalent to sun?os4 so global config works.
4052 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
4054 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
4056 * main.c: Only declare linesize once; declare pagesize not at
4057 all, since it is never used.
4058 (main): Clear newly allocated line before it is used.
4060 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
4062 Further stabilization for the Intel 960.
4064 * Makefile.dist: Parameterize the location of the "include"
4065 and "bfd" directories, as well as "getopt". Add symfile.c.
4066 Link in both dbxread and coffread. Fix up "make depend" to
4067 rewack the locations of include, bfd, and getopt in its output.
4069 * README: Document moving include files, improve some of
4072 * coffread.c: Move common code out to symfile.c. Change
4073 symbol_file_command style interface to use new *_symfile_init
4074 and *_symfile_read interface under BFD. Use BFD internal
4075 info to locate line table, symbols, etc.
4077 * core.c (core_fetch_registers): Rename to get_core_registers
4078 to avoid confusion with fetch_core_registers.
4079 (register_addr): Move to coredep.c, which is already machine
4080 dependent. This leaves core.c pretty clean of dependencies.
4082 * coredep.c (register_addr): Accept this routine from core.c.
4084 * dbxread.c: Move common code (with coffread.c, etc) into new
4085 symfile.c. Each psymtab now contains a pointer to the
4086 format-dependent function that knows how to read it in. Make
4088 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
4089 (process_one_symbol): Add code to complain about a "compiler bug
4090 we muzzle here", if we actually see it.
4092 * eval.c (evaluate_subexp): Insert missing "break" statements
4093 in code that determines whether a variable is an lvalue in
4094 memory, register, or whatever. I detected this via a compiler
4095 bug in which it *almost* mashed out the whole switch statement.
4097 * gdb-int.texinfo: Add minor sections on configuring gdb for
4098 release, and about the README file.
4100 * infcmd.c (registers_info): Fix formatting somewhat. Still
4101 not as pretty as before, but it handles byte swapping.
4103 * remote-nindy.c: If data cache routines are interrupted while
4104 waiting for the remote end, be sure that any uninitialized cache
4105 blocks are on the free list, not on the valid list!
4107 * symfile.h: Flesh out this header file with all the various
4108 routines and variables that have been merged in from dbxread.c
4109 coffread.c, and symtab.c to symfile.c.
4111 * symfile.c: New file, containing code common to dbxread.c,
4112 coffread.c, and some code from symtab.c. All generic code for
4113 reading symbol files should be in here now.
4114 (unrecord_misc_function): Remove unused function.
4116 * symtab.h: Remove file-reading things to symfile.h.
4118 * symtab.c: Remove file-reading things to symfile.c.
4120 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
4121 to decode i960 fault types.
4123 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
4124 target.c: Change type of the "resume" function from int to void,
4125 since its result was never used.
4127 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
4129 * main.c: Replace "stupid" with "caution"; you now "set caution
4132 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
4134 * infcmd.c (do_registers_info): Call val_print to deal with the
4135 byte order of the registers being printed. FIXME, this makes
4136 the formatting of the output uglier.
4138 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
4139 defined, call it for signals the debugger doesn't itself use.
4140 The i960 uses this for more detailed fault information.
4142 * remote.c (remote_open): If arg is null, print help rather than
4145 * sparc-xdep.c (register_valid): Avoid declaring size, since
4146 various modules will think of various sizes depending on the
4147 architecture of their tm-file. FIXME, we need protection against
4148 actually entering one of those modules, which would clobber
4149 storage if not for the target architecture compiled into gdb.
4151 * stack.c (up_command, down_command): Always print the frame
4153 (up_silently_command, down_silently_command): New commands
4156 * i960-pinsn.c (reg), i960-tdep.c: Lint.
4158 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
4159 more parameters than it used to.
4161 * findvar.c (registers): Increase slop to 256 bytes, which should
4162 protect us against even most RISC machines with large register
4164 (locate_var_value): Move declaration inside related ifdef.
4166 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
4167 throughout, to avoid throwing away buffered input from the board.
4168 (nindy_wait): Supply_register takes addr_of_value, not value.
4169 (i960_print_fault): Renamed from i80960_fault.
4170 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
4171 (nindy_store_registers): Avoid regs_changed stuff, just stuff
4173 (nindy_create_inferior): Don't bother to write PC_REGNUM since
4174 we can set the PC in the call to proceed(). Unpush nindy_ops
4175 before pushing it on top, to avoid message to user. Eliminate
4176 commentary from Unix machines that just misleads here.
4177 (reset_command): Fix error message to suggest target command.
4179 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
4181 Release 3.92.5 as frozen.
4183 Stabilize the merged release...with help from lint, Saber C,
4186 Everywhere: Add include files needed to declare return types
4187 of functions called.
4189 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
4191 * breakpoint.h: Add undeclared breakpoint functions, and some
4192 functions for display handling since I couldn't think of a better
4195 * breakpoint.c (insert_breakpoints): Make code for disabling
4196 shared library bkpts more likely to work. It's used when we
4197 rerun a program and stop before the shared library has been
4199 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
4200 cast from pointer, so it squeezes through catch_errors.
4201 (bpstat_stop_status): Fix logic broken some time ago. We now
4202 always create a bpstat if the stop address matches a breakpoint,
4203 even if we don't stop there -- just like the old code used to do
4204 before I got my fingers into it (sigh).
4205 (breakpoint_1): Print "ignore count" after "stop only if"
4206 condition, since that's how it actually works.
4207 (mention): Handle watchpoints as well as breakpoints.
4208 (watch_command): use set_raw_breakpoint and mention to do most
4209 of the work (and initialize all the fields!). Only pass one
4210 arg to parse_c_expression, since that's all it takes.
4212 * command.c (not_just_help_class_command): Rename arg to args
4213 since we ignore "unused argument" warnings on vars named "args".
4214 inflow.c (child_terminal_info): ditto.
4215 infptrace.c (kill_inferior): ditto
4216 main.c (catch_errors, version_info, quit_command, pwd_command,
4217 source_command, dump_me_command, editing_info,
4218 set_history_size_command, set_history, show_history,
4220 stack.c (locals_info): ditto
4221 target.c (target_files_info): ditto
4222 valprint.c (set_input_radix, set_output_radix): ditto
4224 * core.c: Remove old variables for handling core and exec file
4225 sections (data_start, data_end, stack_start, stack_end,
4226 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
4227 text_end, exec_data_start, exec_data_end, text_offset,
4228 exec_data_offset, data_offset, stack_offset). They're
4229 superseded the more general build_section_table and
4231 (get_exec_file): Mention the `file' command.
4232 (read_memory_check): Rename to memory_error, and only call it
4233 in the case of an actual error.
4234 (read_memory, write_memory): call memory_error.
4235 (core_fetch_registers): Register section name is ".reg".
4237 coredep.c: Remove a bunch of crud now that all this file does
4238 is pull the registers out of a core file.
4239 (fetch_core_registers): Rewrite to actually work, I hope.
4241 dbxread.c: Use a.out.gnu.h, not system a.out, now.
4242 Replace index() with strchr(). Remove all the pre-BFD macro
4243 definitions for accessing the symbol file.
4244 (struct dbx_symfile_info): Encapsulate the information that
4245 dbx_symfile_init needs to pass to dbx_symfile_read in this
4248 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
4249 dbx_symfile_discard): Rearrange symbol file reading to divide
4250 the format-specific part from the format-independent part,
4251 leaving the format-independent part such as file name expansion
4252 and opening in symtab.c. This replaces
4253 partial_symbol_file_open and partial_symbol_file_read.
4254 Symbol_file_read, add_file, add_file_target_command,
4255 add_file_addr_command move to symtab.c. Pass an explicit
4256 "mainline" flag for when reading the main symbol table, rather
4257 than relying on the offset address to be zero or nonzero.
4259 (dbx_symfile_read): Don't allow void *'s to be printed as
4261 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
4262 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
4263 macro" debug version really work.
4264 (read_dbx_symtab): Remove unref'd parameter inclink.
4265 Avoid swapping N_SLINE symbols, for speed.
4266 Merge N_TEXT!N_EXT case with the other external symbol
4267 definitions' case. Add comments.
4268 (start_psymtab): Allocate the symfile name in the psymtab on
4269 the psymbol_obstack, rather than using the caller's storage.
4270 (end_psymtab): Only allocate a dependencies list if there are
4272 (psymtab_to_symtab_2): Use BFD when reopening file to read
4273 its symbols for real.
4274 (read_struct_type): Add FIXME comments where it needs work
4276 (read_huge_number): Add FIXME about overflows.
4277 (read_range_type): Add FIXME about comparing a long to 1<<32.
4279 * coffread.c: Minor changes to move things closer to the new
4280 regime with symtab.c and dbxread.c Major work is still needed
4283 * exec.c (exec_file_command): Remove old variables (see core.c
4285 (xfer_memory): If memory transfer is right at the end of a
4286 section, don't lose.
4288 * findvar.c (get_saved_register): If value is in a real
4289 register, LVAL is lval_register, not lval_memory.
4291 frame.h: Declare print_sel_frame and record_selected_frame.
4293 gdb-int.texinfo: New file, for GDB internals documentation.
4294 Very simple, unformatted doc of cleanups is there for now.
4296 gdbcore.h: Remove obsolete variables that described a.out
4297 section addresses and offsets. (See core.c above.)
4298 Declare fetch_core_registers and registers_fetched.
4300 getopt.c: Declare char *alloca(); even on SPARC.
4302 infcmd.c (run_command): Call target_kill rather than
4304 (step_command, next_command, stepi_command, nexti_command):
4305 Declare from_tty parameter even though we don't use it.
4306 (run_stack_dummy): argument BUFFER is a char array, not
4307 a pointer to REGISTER_TYPE.
4308 (finish_command): using_struct_return needed a value *,
4309 not a struct symbol *.
4311 * infptrace.c (child_xfer_memory): To avoid dependency on
4312 where sections are in memory, try PT_WRITE_D and if that fails,
4313 try PT_WRITE_I. Most Unixes don't care which you use.
4315 * infrun.c (step_resume_break_shadow): Change to array to
4316 match other breakpoint shadow storage.
4317 (clear_proceed_status): Pass address of bpstat to
4318 bpstat_clear, not the bpstat itself.
4319 (child_create_inferior): FIXME comment about if the child
4321 (start_inferior): Remove old function.
4322 (child_open): Use target_kill rather than kill_inferior.
4323 (wait_for_inferior): Ditto.
4324 (insert_step_breakpoint, remote_step_breakpoint): Use
4325 new step_resume_break_shadow.
4327 * inftarg.c (child_wait): If all child processes die,
4328 pretend that the one being waited for exited with signal 42.
4330 * main.c (command_line_input): When scanning for comments,
4331 don't coredump on unclosed quotes.
4332 (quit_command): Use target_kill rther than kill_inferior.
4333 (_initialize_main): Rename class_user from "user" to
4336 * printcmd.c (print_command_1): Initialize "fmt" if no format
4337 is specified by the user.
4338 (print_frame_args): Only add to args_printed if we are
4339 actually fetching args from the stack (avoiding undefined
4341 (_initialize_printcmd): Remove bogus \{ from string.
4343 * remote-eb.c (eb_open): Avoid coredump on no argument.
4345 * remote-nindy.c: Bring out of Intel environment into new
4346 target environment. Remove all conditional compilation on
4347 I80960. Massive hacking throughout.
4348 (nindy_xfer_inferior_memory): New routine stolen from
4350 (nindy_create_inferior): New routine pieced together, probably
4351 not quite working yet.
4352 (nindy_ops): New target_ops struct for nindy.
4354 * remote-vx.c: Use write_memory rather than target_write_memory
4355 to get error checking.
4356 (vx_add_file_command, vx_open): Use symbol_file_add rather than
4358 (vx_create_inferior): Use target_terminal_ours...
4360 * signame.c (_initialize_signame): Always initialize, since
4361 we need the table for things other than psignal.
4363 * solib.c (solib_add): Use symbol_file_add, not add_file.
4364 (solib_address): Return boolean result rather than struct
4365 pointer which nobody else knows the type of.
4367 * sparc-tdep.c, valops.c: Use write_memory rather than
4368 target_write_memory, to get error checking.
4370 * stack.c (locals_info, catch_info, args_info,
4371 get_selected_block, frame_command, up_command): Use
4372 target_has_stack, rather than have_inferior_p or
4375 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
4377 * symfile.h: New file, defining the interface between the
4378 generic and object-file-specific symbol reading code.
4380 * symtab.c: Move generic symbol-reading interface to symtab.c,
4381 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
4382 table to map BFD targets to symbol-reading modules in GDB.
4383 Change index to strchr.
4384 (lookup_struct_elt_type): Use error() rather than hand-made
4385 simulations thereof.
4386 (lookup_partial_symbol): Speedup slightly when length == 0.
4387 (symbol_file_add): New function.
4388 (symbol_file_command): Call it.
4389 (symfile_open, symfile_init): New function.
4390 (add_file_target_command, add_file_addr_command): moved from
4393 * target.c (target_command): use target_kill.
4395 * target.h (target_files_info): Don't declare, never called
4398 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
4399 files to determine stack end address.
4401 * valarith.c (value_x_binop, value_x_unop): Change error message
4402 to be more useful. Pass proper argument to value_struct_elt.
4404 * valops.c (value_assign): FIXME comment that long long
4405 bitfields will break here.
4407 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
4408 Update `make saber_gdb' to work better.
4410 * TODO: A woman's work is never done.
4412 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
4413 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
4414 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
4415 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
4416 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
4417 valops.c, valprint.c, exec.c: Lint.
4420 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
4422 Continuing Intel 960 port merge of GDB.
4424 * Makefile.dist: Merge i960 "nindy-share" files. Rename
4425 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
4426 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
4427 Wack over "make depend" so it handles files in subdirectories
4428 vx-share, nindy-share, bfd, and in the current directory.
4430 * blockframe.c (get_prev_frame_info): Remove fatal error
4431 if stack not defined.
4433 * core.c (core_open, core_detach): New functions that handle
4434 the old "core-file" command as "target core" and "detach" instead.
4435 (core_file_command): Call them.
4436 (core_xfer_memory): Use common routine xfer_memory.
4438 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
4439 dbxread now uses bfd for everything but symbol reading itself.
4440 BFD internals are used to drag out the relevant file offsets.
4441 (partial_symbol_file_open): Change args all around for BFD.
4443 * symtab.c: Rename "value" to "val" everywhere, so we can
4445 (symbol_file_command): New command, moved from dbxread.c
4446 and coffread.c. It uses BFD to read the file, then vectors
4447 based on its type, to dbx or coff symbol readers.
4448 * symtab.h: Extern a few vars for symbol_file_command.
4450 * target.h: Breakpoint takes a char * save area, not a char **.
4452 * valprint.c (val_print): When unpacking bitfields, offset
4453 the address in gdb of the value, if it is declared with a shorter
4454 type. Remove the last "runtime kludge test" of host byte order.
4456 * utils.c: Remove old my_bfd_read routine.
4458 * stack.c (frame_info): Use target_has_stack. Print program counter
4459 register's actual name rather than "pc", since it's called the
4460 "ip" (instruction pointer) on the i960 (sigh).
4462 * target.c (target_command): Add command for selecting a target
4463 type and calling its open routine. This is used for initiating
4464 communication with a particular target, in a generic way.
4466 * tm-i960.h: Update for modern gdb. Remove semicolons from
4467 various macros. Handle reading struct return convention, and
4468 error-out attempts to return structs with the "return" command.
4469 Be sure gdb doesn't think we know how to call functions in the
4472 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
4473 to i960_xxx in lower case.
4474 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
4475 not being defined yet.
4477 * remote.c (remote_open): Call start_remote to initialize
4478 wait_for_inferior during open.
4479 (remote_xfer_inferior_memory): Return length written rather
4482 * remote-vx.c (target_command -> vx_open): Use new generic
4484 * remote-eb.c, inftarg.c, exec.c: ditto.
4486 * infrun.c: Fix comments.
4487 (attach_program -> child_open): Use new generic target command.
4488 (wait_for_inferior): Clear saved register values before target_wait,
4489 so target_wait can set some of them if convenient.
4491 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
4492 Return success indicator, not void.
4493 (child_xfer_memory): Avoid fetching initial word if we'll
4494 overwrite it anyway.
4496 * infcmd.c (attach_command): Use new generic target open routine.
4497 (_initialize_infcmd): Update doc on attach and detach commands.
4498 (do_registers_info): Merge in a byte-order problem as a FIXME
4501 * findvar.c (find_saved_register): Avoid problem in current frame.
4502 (read_relative_register): Ditto.
4503 (write_register): Convert byte order on the way out.
4505 * exec.c (file_command): Add.
4506 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
4507 (xfer_memory): Common function between core_xfer_memory and
4509 (exec_xfer_memory): Use it.
4511 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
4513 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
4514 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
4515 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
4517 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
4519 Merge Intel 960 port of gdb, continuing...
4521 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
4522 symbol_file_command): Pass from_tty arg to hush 'em up.
4524 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
4525 Add magic numbers for 960 COFF format.
4527 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
4529 Merge Intel 960 port of gdb, from Intel "1.2" release.
4531 CHANGE_LOG entries from their port, which was based on
4534 Thu Sep 6 11:02:22 PDT 1990
4535 Remove temp file if download is interrupted.
4537 Wed Aug 1 09:08:33 PDT 1990
4538 Now uses binary protocol to talk to NINDY.
4539 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
4540 Times out after 5 seconds when trying to talk to NINDY.
4542 Tue May 29 12:54:49 PDT 1990
4543 Added variable baud rate (-b switch).
4544 Source code reorganization.
4546 Thu Apr 26 11:09:55 PDT 1990
4547 More cleanup of batch mode; specifically, execute "-s", "-e", and
4548 "-se" switches as soon as they are encountered on the invocation line.
4550 Fri Apr 20 13:47:15 PDT 1990
4553 Thu Apr 19 09:54:28 PDT 1990
4554 Add 'reset' command.
4556 Wed Apr 18 09:48:07 PDT 1990
4557 After opening remote tty, wait for 1 second to go by without input
4558 from it before trying to talk to NINDY (fixes problems with the
4559 Heurikon HK80/V960E).
4561 Mon Apr 4 16:33:05 PDT 1990
4562 Some output was not being suppressed in 'batch' mode.
4564 Thu Mar 22 15:31:11 PST 1990
4565 Ask user if old symbol table should be deleted when new file is
4568 Allow user to run a program downloaded before gdb960 was brought up.
4570 Correct "exec-file" help message for i80960 context.
4572 Correct bug in calculating user space address: could occasionally
4573 corrupt user program.
4575 Make sure to zero low-order bits in rip's because of bug in 960CA
4576 A-step part: could cause operation faults when "next"ing across
4579 Correct bug that made it impossible to get source line numbers for
4580 code loaded at addresses higher than 0x7fffffff.
4582 Wed Jan 10 12:43:22 PST 1990
4583 Open remote tty for exclusive use.
4585 Fri Jan 5 12:14:42 PST 1990
4586 Correct disassembly (CA manual was right after all):
4587 opcode for sysctl is 0x659
4589 Mon Oct 23 12:03:04 PDT 1989
4590 Use G960BASE and G960BIN environment variables to find 'sx' utility.
4592 Mon Oct 16 14:15:09 PDT 1989
4593 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
4595 Mon Oct 2 15:56:31 PDT 1989
4597 Added 960CA disassembly support.
4599 To simplify maintenance:
4600 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
4602 - eliminated opcode.h: incorporates tables into i960-pinsn.c
4603 - moved 960-specific routines from i960-pinsn.c to i960-md.c
4604 - made disassembly interface identical to that in gdmp960.
4608 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
4610 * target.h: Allow targets to stack. Add target_has_memory,
4611 _registers, etc. Restructure memory access and "info files"
4612 to walk the target stack.
4613 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
4614 target.c: Change tables to match target.h.
4615 * inflow.c (child_mourn_inferior): pop child_ops.
4616 (generic_mourn_inferior): Use new has_stack flag.
4617 * infptrace.c (child_xfer_memory): New memory regime.
4618 * inftarg.c (child_files_info): New "info files" regime.
4619 * remote-eb.c: New memory regime, new info files.
4620 * remote-vx.c: New memory regime, new info files. Now use
4621 separate targets for VxWorks attachment to machine, and
4622 actually running a process under VxWorks, since one has
4623 stack & execution & regs and the other doesn't.
4624 * remote.c: New memory regime, new info files.
4625 * sparc-xdep.c (fetch_core-registers): New memory regime.
4626 * target.c: New routines and support for stacked targets,
4627 new memory regime, new info files regime.
4630 Generalize section handling for an arbitrary number of sections,
4631 including use of the new BFD (binary file) library.
4632 * gdbcore.h: Add struct section_table.
4633 * exec.c (build_section_table): Iterate all sections and
4634 record what gdb needs to know about them.
4635 (exec_command): Use it.
4636 (exec_xfer_memory): Use the table.
4637 (exec_files_info): Print the table.
4638 * core.c (core_file_command, core_xfer_memory, core_files_info):
4640 * source.c (find_source_lines): Use bfd_get_mtime.
4641 * dbxread.c: Quick changes to make it compile with new BFD.
4642 * utils.c (error): Avoid using bfd_error in generic routines.
4644 * core.c (core_fetch_registers): Get from the ".regs" section of
4646 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
4648 * inferior.h (attach_flag): Export.
4649 * infcmd.c (run_command): use new target_create_inferior.
4650 * infrun.c (child_create_inferior): Don't return result.
4651 * Makefile.dist (VERSION): 3.91.4.
4653 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
4655 * breakpoint.c (bpstat_num): Handle breakpoints which have
4656 since been deleted, such as temporary breakpoints.
4657 infcmd.c (program_info): ditto.
4659 * core.c (core_file_command): Display the frame where the core
4664 * remote-vx.c (target_command): Merge in target command from
4665 targ-vx.c. A few other cleanups.
4667 * TODO, Projects: Lots more stuff to do...
4669 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
4671 Massive changes to wall off the remote-debugging interface
4672 behind a function vector. The port to handle VxWorks targets
4673 is also part of this.
4675 All files: Replace references to renamed functions,
4676 remove references to remote_debugging, remove references to
4677 have_include_file, have_core_file in favor of target_has_stack,
4678 target_has_memory, etc.
4680 * Modularize the breakpoint interface.
4681 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
4682 a breakpoint instruction.
4683 breakpoint.c: struct breakpoint's shadow_contents now sized as
4685 (insert_breakpoints): Vector to target to install breakpoints.
4686 (remove_breakpoints): Vector to target here too.
4687 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
4688 sparc-tdep.c (single_step): Use new breakpoint interface for
4689 the single-step breakpoints.
4690 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
4691 New file, contains routines to insert and remove breakpoints by
4692 reading out the old contents and later replacing them. This is
4693 how ptrace breakpoints work, and many remote systems as well.
4695 * tm-vxworks68.h: New config file, overrides a few things for
4696 Wind River's preferences.
4698 * target.h: New file, for transfer vector used to talk to the
4699 inferior (child, attached, core, exec, remote, etc). All accesses
4700 to the thing being debugged should come through these vectors.
4701 target.c: New file, routines to handle transfer vector.
4702 (various files): Add transfer vectors XXX_ops for the various
4703 targets and pseudo-targets (core files, etc) we support.
4705 * breakpoint.c (bpstat_stop_status): Further explorations of
4706 watchpoints and why things don't work all the time.
4707 (bpstat_alloc): New fn to allocate a bpstat and chain it.
4709 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
4710 the local gdbinit if it doesn't already have it.
4712 * core.c (core_ops): add and install.
4713 Allow core debugging without exec file.
4715 * dbxread.c (free_and_init_header_files): Merge two fns.
4716 (end_symtab): Free named symbol table when a new version comes in.
4717 (read_dbx_symtab): Relocate all kinds of symbols with base
4718 address. First step toward handling different text, data, bss
4720 (add_file_addr_command): Renamed add_file_command.
4721 (add_file_command): Vector to remote handler.
4722 Add "load" as an alias for "add-file" command.
4724 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
4725 non-returning functions.
4727 * exec.c: Add exec_ops, and push it as a target when an exec
4730 * infcmd.c (run_command): Pass executable file name and arg list
4731 separately when starting an inferior. Permit "run" when no exec
4732 file is specified, for VxWorks.
4733 (detach_command): Move to child_detach in inftarg.c.
4735 * inftarg.c: New file. Unix-child-specific routines, and the
4736 child_ops structure.
4738 * inferior.h (registers): Export "registers" as the way for
4739 target dependent register handlers to find gdb's local copy of
4740 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
4741 since it is now used by places that want wait_for_inferior to
4742 handle the grunge but want to see every trap from the inferior.
4744 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
4745 Eliminate remote_debugging hooks in terminal handling.
4747 * infrun.c: Replace start_inferior with child_create_inferior.
4748 Move all the hair of Unix shells and ptrace idiosyncracies into
4749 child_create_inferior, so remote handlers don't have to deal.
4750 Remove running_in_shell. Rename stop_after_attach to
4751 stop_soon_quietly, and use it in a few other places where we want
4752 to just call wait_for_inferior and get control back on the first
4753 trap. trap_expected now never takes a value > 1.
4754 (init_wait_for_inferior): Initialize static vars when a new
4757 main.c (gdbinit): Add new hook for .gdbinit file name, let
4758 it be overridden by config files as GDBINIT_FILENAME.
4759 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
4760 Both of these are used for VxWorks gdb.
4762 mcheck.c: rename include file "gmalloc.c" to avoid problems
4763 with system include file "malloc.c".
4765 param-no-tm.h: New include file, same as param.h but does not
4766 include the default "tm.h" file. This is used in files where
4767 the target is known, e.g. remote-eb.c or sparc-xdep.c.
4769 param.h: Now just a shell that includes tm.h and param-no-tm.h.
4771 remote-vx.c: New file, VxWorks remote debugging support. Uses
4772 RPC routines that are shared with the target system, in directory
4775 remote.c: Vectorize remote interface.
4777 source.c: Globalize source_path, and make an alias "l" for "list"
4778 since we now have the "load" command.
4780 sparc-xdep.c: Use new param-no-tm.h.
4782 symmisc.c (free_named_symtab): Add new function from Wind River.
4783 However, ifdef it out for now while we think about what it should
4786 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
4788 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
4789 non-Unix-children handle this with their own code in the target
4792 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
4793 source and target lists. Add vx-share to default list of include
4794 directories. Add new files to src and target lists: mem-break,
4795 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
4796 ${srcdir} versions of munch and createtags are used.
4798 * valops.c (find_function_addr): Split out of call_function.
4799 (call_function_by_hand): Rename call_function; this function
4800 calls functions in the target by laboriously patching the target
4801 word-by-word with the right stack, args, regs, etc.
4804 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
4806 Handle AMD 29000 a bit better.
4808 * remote-eb.c (readchar): Mask received char log to make it readable.
4809 (remote_start): Pass arguments down to executing program.
4810 Make startaddr unsigned.
4811 infrun.c (start_inferior): Accept args, pass them to
4813 infcmd.c (run_command): Pass args down to start_inferior.
4815 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
4816 the target object file format.
4817 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
4819 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
4820 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
4822 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
4824 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
4825 * TODO: We did a few things, we have more to do though.
4827 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
4828 * inflow.c (inferior_died): Clear deferred stores.
4830 * Debug problems with dummy frames and calls to the inferior.
4831 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
4832 * sparc-tdep.c (do_restore_insn): Simplify.
4833 (sparc_frame_find_saved_regs): Simplify and fix what we find.
4834 (sparc_push_dummy_frame): Simplify and fix what we push.
4835 (sparc_pop_frame): Slightly more hair here, deciding whether
4836 we are restoring a saved PC or returning to a return address in %i7.
4837 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
4839 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
4840 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
4841 * obstack.h (chunkfun): ditto.
4842 * defs.h (xmalloc, xrealloc): ditto
4844 * utils.c (quit): Grab the terminal from the child if necessary.
4846 * inflow.c (term_status_command): Rename to term_info, change
4849 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
4850 (is_delayed_branch): Speed up.
4851 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
4852 Still missing some float ops, and needs testing.
4854 * Support for input and output radixes other than base 10
4855 * defs.h (input_radix, output_radix): Declare.
4856 * expread.y (yyparse, parse_number): Handle changes of input
4857 radix, and ambiguous names-or-numbers in radixes >10.
4858 * printcmd.c (print_scalar_formatted): Print formatted hex
4859 numbers in varying column widths.
4860 * valprint.c (val_print): Use output_format to print scalar ints.
4861 (set_input_radix, set_output_radix, set_radix): Create.
4862 (set_output_radix): Set output_format from output_radix.
4863 (_initialize_valprint): add `set radix' but leave the others off.
4865 * main.c (execute_command): Let stupid questions be turned off.
4866 (_initialize_main): Handle "set stupidity", etc.
4868 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
4869 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
4871 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
4873 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
4874 bfd stuff is still screwed up, but with some manual work, it
4877 * breakpoint.c (bpstat_do_actions): Start over if a command
4878 proceeds the inferior, since the inferior will have stopped and
4879 will need to have its new stop-actions taken care of.
4881 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
4882 compiler fits, simplify it.
4884 * gdb.texinfo (directory command): Doc new dir command.
4885 source.c (directory_command): "dir" now puts things on the front
4886 of the path, moves dups up front, and handles multiple names
4887 on the command line, inserting each one in order. It also
4888 blows away cached line and full_filename info.
4890 * stack.c (backtrace_command): Skip "more stack frames follow"
4893 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
4894 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
4895 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
4896 The only odd one was Gould NP1, which had defined vprintf to
4899 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
4900 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
4901 variable, inspect_it.
4902 valprint.c (print_string, val_print): Use the global inspect_it
4903 to indicate whether to print in Epoch style or normal style.
4905 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
4907 * printcmd.c (call_command): add an alias for the "print" command
4908 which runs expressions and doesn't print the result if void.
4909 (print_command_1): implement it.
4911 * command.c: Remove #if 0'd code. Initialize all the fields
4912 in add_cmd (). Rename do_nothing_command to
4913 not_just_help_class_command, and make it externally visible.
4914 command.h: add user_commands to struct.
4915 * main.c (define_command): Don't overload c->function with a char
4916 string as well as a function pointer.
4918 * eval.c (evaluate_subexp): Reinstall tiemann changes to
4919 calling convention of value_struct_elt () that got dropped in
4922 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
4923 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
4925 * tm-sparc.h (POP_FRAME): replace some constants with defines.
4927 * sparc-xdep.c (store_inferior_registers): defer stores to regs
4928 until a good time (e.g. when we are about to run the child),
4929 saving ptrace calls.
4930 * infrun.c (proceed): handle DO_DEFERRED_STORES.
4931 * tm-sparc.h: define DO_DEFERRED_STORES.
4933 * sparc-xdep.c (store_inferior_registers): when storing float
4934 registers, don't store stack regs too. When storing the SP,
4935 however, DO store the stack regs too. This fixes a bug in which
4936 the dummy frame is not recognized when a call_function finishes,
4937 because its frame pointer (in the stack regs) was never
4939 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
4940 even though we don't know how to read them from an inferior.
4941 valops.c (call_function): Comment about storing SP.
4943 * infrun.c (save_inferior_status): Save away the original bpstat
4944 chain so it can be restored later. Install the copied version for
4945 use by whoever saved the status. It will be blow away by
4946 restore_inferior_status, and the original chain restored. This is
4947 important for people who have pointers into the original.
4949 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
4950 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
4951 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
4954 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
4956 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
4957 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
4958 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
4960 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
4962 * Merge Mike Tiemann's multiple inheritance changes from Sun.
4963 Store the baseclasses in a type struct starting from array element
4964 0 rather than from the unusual array element 1.
4966 dbxread.c: the above.
4967 (virtual_context): Add
4968 Read new debug information about which virtual function table
4969 a virtual function is from, and store it in fn_field.fcontext.
4971 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
4972 TYPE_FN_FIELD_STATIC_P.
4974 symtab.c: the above.
4975 valops.c: the above. Handle pointer casts of object *'s.
4976 (search_struct_method): Add.
4977 (value_struct_elt): First arg is now a pointer to a value, and is
4980 valprint.c: the above.
4981 values.c (value_virtual_fn_field): Add type arg. Handle
4982 offsetting to the proper object when calling virtual fns.
4984 (baseclass_addr): Add valuep arg.
4986 * README: Document the current state of BFD config (missing).
4987 * TODO, ChangeLog, Makefile.dist: Roll version.
4988 * WHATS.NEW: Add summary of changes since 3.5.
4990 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
4992 * dbxread.c (read_struct_type): Clear bit vectors whenever
4994 symtab.c (B_CLRALL): define.
4996 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
4997 using == rather than =. Huh... This fixes the dreaded problem
4998 wherein builtin_type_int becomes TYPE_CODE_FLT.
5000 * core.c (info_files): Show the inferior pid.
5002 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
5003 already knows how to look in the source directory.
5005 * Remove psymtab hair from many places. Remove duplicated code
5006 for searching symbol tables. Hide psymtabs from most places.
5007 Make it fast to get from a psymtab to its symtab.
5009 blockframe.c (blockvector_for_pc): Remove psymtab hair.
5010 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5011 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5012 dbxread.c: export psymtab_to_symtab, make it work if called N times.
5013 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
5014 new symtab completely. New psymtabs get symtab pointer
5015 initialized to zero. Remove MI warning printf.
5016 symtab.h: Comments. Add psymtab to symtab pointer.
5017 (PSYMTAB_TO_SYMTAB): New macro.
5018 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
5019 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
5021 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
5023 (print_frame_info): Avoid special-casing symbols that have not yet
5026 * source.c (open_source_file): Quick path if we have already
5027 located the source file by its full name.
5029 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
5030 find_pc_psymtab. When a name is found in the misc function
5031 vector, search the symbol table for its mangled name, not the
5032 name that the user typed.
5034 * bfd.h: Fix missing comment terminators, make #endifs match.
5036 * valarith.c (value_less): Handle unsigned int comparisons.
5037 Add FIXME about pointer compares, which assume host and target
5038 pointers are the same.
5040 * command.c (do_nothing_command): lint
5041 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
5042 fix comments on debug symbol format for visibility. Actually set
5043 visibility of symbols.
5044 main.c (echo_command): lint; use <readline/history.h>.
5045 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
5046 obstack.h (_obstack_blank): Rearrange pointer math to avoid
5047 pointing past end of allocated memory; saber complains.
5048 obstack.h: Declare the external functions that we use.
5049 valarith.h: use <string.h>
5050 solib.c (solib_add): lint.
5052 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
5054 * main.c (initialize_main): Default info_verbose to off, now that
5055 symbol reading is fast.
5056 (quit_command): Avoid clobbering exec_bfd while quitting.
5058 * Initial BFD (binary file diddling library) merger:
5059 coffread.c: Change AOUTHDR to struct exe_hdr.
5061 core.c: initialize initialized data at compile time.
5062 (core_file_command): Move from coredep.c, convert to bfd.
5063 (xfer_core_file): Convert to bfd.
5064 exec.c (exec_file_command): use bfd routines.
5066 mips-tdep.c: Remove exec_file_command and friends.
5069 * coredep.c: (fetch_core_registers) Convert core_file_command to
5070 fetch_core_registers.
5071 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
5073 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
5074 (my_bfd_read): More bogosity, which I don't think we call.
5075 (program_name): Remove this atrocity asap!
5077 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
5080 values.c: allocate_repeat_value was not clearing the
5081 optimized_out field.
5082 (value_static_field): minor stylistic fix (wrong macro was used).
5083 valops.c (value_struct_elt_for_address): didn't work for C++
5086 * signame.c (_initialize_signame): Initialize signal names once.
5088 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
5089 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
5090 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
5092 * remote-eb.c: Support user-settable baud rates on the serial port.
5094 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
5096 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
5098 * tconfig/sun3os4: Remove warning about native assembler,
5099 since it also occurs in the xconfig file.
5101 * findvar.c (registers): Allocate some slop after `registers'
5102 to prevent stray accesses from trashing the next variable.
5104 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
5105 on the sun-3, by changing the #ifdef from `sun3' (which is not
5106 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
5107 vars, which happened to follow `registers' in the executable.
5109 * readline/history.c (history_search): Heed gcc-2's advice
5110 and parenthesize && inside ||).
5112 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
5113 tm-29k.c: Insert FSF copyright headers.
5115 * remote-eb.c: Better comments.
5117 * Makefile.dist: Update to 3.91.6.
5118 * TODO: note PREPARE_TO_STORE problem.
5120 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
5122 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
5124 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
5126 * infrun.c (wait_for_inferior, at end): Don't set up
5127 prev_* if the inferior no longer exists.
5129 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
5130 CANNOT_EXECUTE_STACK.
5131 valops.c (call_function): Use it.
5133 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
5135 * inferior.h (PC_IN_CALL_DUMMY): New macro.
5136 infrun.c (wait_for_inferior, 2 places): Use it.
5138 * values.c (value_being_returned): Only use
5139 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
5141 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
5142 right thing for remote-eb.c.
5144 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
5145 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
5147 * blockframe.c: Put get_frame_saved_regs inside #if !defined
5148 (FRAME_FIND_SAVED_REGS).
5150 * findvar.c ({fetch,store}_registers): Check for
5151 REMOTE_{FETCH_STORE}_REGISTER macro.
5153 * findvar.c (get_saved_register): Add argument lval and
5154 change meaning of argument addr.
5155 findvar.c: Change calls to get_saved_register to reflect
5156 new calling convention.
5157 valops.c (value_assign): Use get_saved_register instead of
5158 find_saved_register.
5160 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5162 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
5163 an (uninitialized) pointer to one. Use "&" when passing it
5166 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5168 * coffread.c (getfilename): Use DGUX x_offset and x_name if
5171 * coffread.c (symbol_file_command): Put semicolon after
5173 Put safe_to_init_tdesc_context in #if defined (TDESC).
5174 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
5175 coffread.c: #include <sys/stat.h>.
5176 (read_coff_symtab): Typo: in_source_files -> in_source_file.
5177 Add missing ')' in check for "lc%" and friends. Remove
5179 Declare read_one_sym() at top of file.
5180 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
5181 MC68WRMAGIC can have the same value without causing a duplicate
5184 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
5186 * Allow a Makefile to be built without building the
5187 tm and xm file links that screw up builds in subdirectories.
5188 This is done with `config.gdb none', then you can do things
5189 like `make gdb.tar.Z'.
5190 * tconfig/none: Config file for no target system
5191 * xconfig/none: Config file for no host system
5192 * config.gdb: If no TM or XM files are called out by the
5193 host or target file, don't make links for them.
5195 * cplus-dem.c: Add documentation.
5197 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
5198 simple error, so the user's gdb doesn't crash due to some object
5199 file problem (e.g. somebody is rebuilding the file out from under
5202 * printcmd.c (print_address_symbolic): demangle the symbol.
5204 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
5205 Motorola copyrights in it. Make "make gdb.tar.Z" work.
5206 (alldeps.mak): sort and uniq all results from this; duplicates
5207 hose gdb.tar.Z link building. Remove RCS files from
5208 tconfig and xconfig. Add config files for sun386. Add
5209 a few odd files to OTHERS and HFILES.
5211 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
5213 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
5214 Roll version number to 3.91.5. Make lint work in bindir.
5216 * README: Document cross-debugging and new file structure.
5218 * blockframe.c: Lint. Include "value.h" to declare read_register.
5219 (find_pc_partial_function): remove duplicate line.
5221 * command.h: Lint. Declare error_no_arg and dont_repeat.
5223 * tm-news.h: Remove inadvertently duplicated stuff.
5225 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
5226 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
5228 * config.gdb: Allow `config.gdb host target' form. Clean
5229 up previous change that printed bogus messages when you just said
5232 * core.c: #include "command.h" for lint.
5235 * main.c: Remove some casts of enums. Lint.
5242 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
5244 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
5245 read it from memory. This will allow us to save ptrace calls
5246 eventually. Changed caller single_step too.
5248 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
5249 that we aren't going to use, saving many ptrace calls, especially
5250 when watchpointing or single stepping. Use some #define's for
5252 (store_inferior_registers): Ditto.
5253 (core_file_command): Use some #define's for constants.
5255 * tm-sparc.h: Add #define's for some register numbers, so we
5256 can eliminate the use of random constants in sparc-xdep.c.
5258 * stack.c (frame_command, print_frame_info, up_command,
5259 down_command) Remove frame_changed, since it
5260 causes a bug and doesn't seem to do anything useful. In some
5261 places it was used as a flag, in others as a stack level (?).
5263 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
5264 default is to use the portable (vprintf) version rather than the
5266 * xm-news.h (MISSING_VPRINTF): Add.
5268 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
5270 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
5272 * Remove stuff that forces -Bstatic linking of gdb, and warnings
5273 about linking debugged programs -Bstatic in the sun?os4 config
5274 files in tconfig and xconfig subdirectories.
5276 * main.c (main): Remove unreached exit(0) now that we exit
5279 * Create TODO file for online bug list. There are too many
5280 "little" bugs to keep track of on paper.
5282 * Change Projects file to refer to bug-gdb@cygnus.com
5283 rather than kingdon@ai.
5285 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
5287 * Makefile.dist (VERSION): 3.91.4 now.
5289 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
5290 (condense_misc_bunches): Add sanity check that misc_count is
5291 the same as the number of symbols in the bunch.
5293 * coffread.c: rename init_misc_bunches. Pass an argument
5294 to condense_misc_bunches (a zero).
5296 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
5297 every time we are called; don't rely on our caller to do it.
5298 (add_file): Remove call to init_misc_bunches.
5300 * mipsread.c: Only warn, don't error, if unknown symbol types.
5301 This keeps an old gdb from falling on its face if it sees newly
5302 extended symbol info. Rename init_misc_bunches.
5304 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
5306 * Merge in changes from Per Bothner for DECstations and other
5307 MIPS stuff. The rest is Bothner speaking:
5309 The next message is a merger of Alessando Forin's mips port with
5310 mine. I've tried to use my good if biased judgment to get
5311 the best of both. It *does* need testing.
5313 Some of the changes are general, *not* mips-specific.
5316 Didn't believe in little-endian bit order.
5317 There are still inconsistencies about whether flags
5318 like BITS_BIG_ENDIAN are integer (#if ...) or
5319 boolean (#ifdef ...). I tried to paper over them.
5321 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
5322 Moved some misc_function code that was common to
5323 {dbx,coff,mips}read.c to symtab.c.
5324 In the process, I think I cleaned things up a bit.
5325 At the same time, moved obsavestring and obconcat to symtab.c.
5328 Removed obsolete condense_addl_misc_bunches (use
5329 condense_misc_bunches(1) instead).
5332 Needed to include <sys/dir>, at least on DECstations.
5334 valops.c, mips-tdep.c, tm-mips.h:
5335 Added PUSH_ARGUMENTS macro to support funny argument-pushing
5336 conventions (when STACK_ALIGN is insufficient).
5337 Needed on mips, where doubles need 8-byte alignment,
5338 but ints only need 4.
5341 Removed cruft that was not being used.
5342 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
5345 Print $ before register-names (I think that makes things a little
5347 Never print two instructions, even if one delays.
5348 Removed hex-disassemble set_cmd. (This is not mips-specific,
5349 so I think the argument is whether it is generally worthwhile or not.
5350 I'm inclined to think not, given how easy it is to
5351 convert between radixes in gdb.)
5354 This is basically Alessando's code.
5355 It doesn't use obstacks; I changed it to use obstacks
5356 in a few minor places where using malloc causes a
5357 memory leak. (Probably, more places could/should be changed.)
5358 I added record_misc_function where it was missing.
5359 In symbol_file_command and add_file_command, I tried
5360 to make the code consistent with more recent versions.
5361 Minor sylistic changes in parse_procedure.
5362 Make a .gdbinfo. psuedo-symbol point back to the real
5363 procedure symbol (using the isym field).
5366 This is basically from my port, but with a lot of details
5367 and a number of routines merged in from Alessando's version.
5368 I basically used my code "raw" backtrace (use heuristics
5369 from the actual code, rather than symbol table info) - though
5370 the idea is Alessandro's. I feel my code is a little cleaner
5371 here, particularly in being a little more flexible, such as being
5372 able to handle gcc-produced code (which it now can).
5373 It also doesn't do frame caching (which is not useful
5374 more recent gdb versions).
5375 I also used my code for push_/pop_dummy, more or less.
5376 I tried to incorporate AF's code for testing sigtramp
5377 while backtracing; I probably got it wrong.
5378 Added mips_print_register, which tries to scrunch as much
5379 information as possible on a screen...
5380 Removed the skip-prologue set_cmd. As with hex-disassemble (see
5381 under mips-pinsn.c), I don't see anything mips-specific here,
5382 and I don't see it being all that useful anyway.
5385 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
5386 Use more register names (rather than hard-cases numbers).
5388 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
5390 * Hack up 3.90.11 changes:
5392 * Makefile.dist (depend): parameterize $(GCC).
5393 Add solib.c and solib.o.
5394 (readline): Fix vpath for both absolute or relative SRCDIR.
5396 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
5397 Also, let the part I didn't understand at least compile so
5398 I can test the rest. FIXME.
5400 * dbxread.c: Fix thinko using strcmp.
5401 (init_psymbol_list): declare static.
5402 (partial_symbol_file_open): Comment cleanups better, avoid
5403 cleaning up the string table since the caller will do that.
5404 Move the stat for mod time into symbol_file_command, temporarily.
5405 (There should be a mod time for each symbol file, eventually,
5406 to control its rereading. FIXME.)
5408 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
5409 SunOS, which gives error for shared libs otherwise. (From
5410 Schaefer, probably FIXME needs work for portability.)
5412 * solib.c: Move #include "param.h" to work.
5413 Lowercase all the Uppercase Letters In the Messages.
5414 (find_solib): Clean up inferior_so_name for debug printouts.
5415 Allow no argument, to mean all shared libraries.
5417 * symmisc.c: include param.h to get CLEAR_SOLIB.
5419 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
5421 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
5422 to 3.90.11. ChangeLog entries below are from this.
5424 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5428 * Makefile.dist (HFILES): Add tm-sunos.h.
5430 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5434 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
5436 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
5438 * sparc-opcode.h Added single-operand version of rett.
5440 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5442 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
5443 Put parens around gcc_p in expansion.
5445 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5447 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
5449 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5451 * Changes for Sun shared libraries:
5452 blockframe.c (find_pc_partial_function): If a non-text symbol
5453 is found, set *address = pc - FUNCTION_START_OFFSET.
5454 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
5455 Disable breakpoints instead of giving an error.
5456 source.c (select_source_symtab): Initialize cs_pst.
5457 symmisc.c: Call CLEAR_SOLIB if defined.
5458 symtab.h: Make text{low,high} CORE_ADDR not int.
5459 (psymtab): New field addr.
5461 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
5462 (record_misc_function): Give correct type for N_DATA symbols.
5463 (condense_misc_bunches): do "misc_function_count = j" regardless
5465 Take code which is shared between symbol_file_command and
5466 add_file_command and put it into partial_symbol_file_{open,read}.
5467 Split add_file_command into add_file_command and add_file.
5468 Make psymtab_to_symtab read in the string table if the file
5470 Two new parameters to read_dbx_symtab and start_psymtab.
5471 tm-sunos.h: New file.
5473 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5475 * infcmd.c: Change cont_command to continue_command and "cont"
5478 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5480 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
5482 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
5484 * values.c (USE_STRUCT_CONVENTION): Check for structures of
5485 size 1,2,4,8 rather than size < 8.
5487 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
5488 as necessary, not just once.
5490 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
5492 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5494 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
5496 * tm-news.h: Add CALL_DUMMY_*.
5498 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
5500 * config.gdb: In list_host, list_target, use ${i}, not $i.
5502 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5504 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
5506 * sparc-opcode.h: Change all store floating-point state register
5507 instructions to have the right match & lose fields.
5509 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5511 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
5513 config.gdb: If srcdir != ., create readline directory and
5514 copy a makefile into it.
5516 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
5517 consistency with POSIX.
5519 * breakpoint.c (bpstat_stop_status): Disable watchpoint
5520 when we exit its exp_valid_block.
5522 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
5524 * Makefile.dist: Bump version to 3.91.3.
5526 * Clean up handling of breakpoint commands (somewhat).
5527 Prompted by Tiemann bug report "cont 10" doesn't work any more.
5529 inferior.h: Add breakpoint_proceeded to inferior status struct
5530 and globals; save it and restore it.
5531 (clear_breakpoint_commands): Cleanup, remove old #define.
5533 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
5534 (save_inferior_status, restore_inferior_status): handle it also.
5535 (proceed): Remove earlier code that set breakpoint_proceeded.
5536 It is now set only in clear_proceed_status.
5537 (clear_proceed_status): Cleanup, use bpstat_clear rather
5538 than clear_breakpoint_commands. No callers need the stop_bpstat
5539 between clear_proceed_status and proceed.
5541 infcmd.c: Add breakpoint_proceeded definition and comment.
5542 (cont_command, jump_command, signal_command): Move call to
5543 clear_proceed_status right next to call to proceed.
5545 breakpoint.c (bpstat_do_actions): Avoid clobbering our
5546 caller's argument while running down the chain of breakpoints.
5547 Use new variable "breakpoint_proceeded" to determine when
5548 a command that it executes moves the inferior past the
5550 (bpstat_clear): Handle NULL argument.
5551 (bpstat_clear_actions): Avoid useless call to
5552 breakpoint_auto_delete.
5553 (delete_breakpoint): Clean up bpstat's that are pointing to
5554 the deleted breakpoint from the stop_bpstat chain.
5555 (breakpoint_auto_delete): Simplify.
5557 * Clean up handling of EOF, error on stdin, etc. This was
5558 prompted by a network problem that caused gdb to go into an
5559 infinite loop filling up its malloc'd memory.
5561 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
5562 not clear_breakpoints_commands, which is now gone.
5563 (main): If command_loop returns (e.g. from EOF on stdin), do
5564 a quit_command (looping back to command_loop if quit_command
5565 doesn't really quit).
5566 (command_loop): check result from command_line_input and
5567 exit if it returns NULL, rather than passing the NULL to
5569 (gdb_readline): Free malloc'd result space before returning
5572 * utils.c (query): Handle C-d to mean "yes", just as if the
5573 input was not a terminal. Also avoid infinite loop if EOF
5574 occurs in mid-input-line before newline. This allows
5575 query to be used at EOF on stdin with reasonable results.
5577 * infrun.c (proceed): Set breakpoint_proceeded.
5579 * values.c (value_as_long): Avoid infinite recursion for enums.
5580 (_initialize_values): Fix typo in help msg (kingdon).
5582 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
5583 RL_LIB for linking. This allows -lreadline for linking
5584 and nothing for dependencies, once readline is a real library.
5586 * config.gdb: Jim Kingdon: give useful error message if the
5587 host or target type is not recognized.
5589 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
5590 it just defines it. Dumb, but deal with it.
5592 * Jim Kingdon suggests:
5593 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
5595 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
5597 * Makefile.dist (VERSION): Bump version # to 3.91.2.
5599 * Clean up Bothner's changes.
5601 * blockframe.c (clear_pc_function_cache): New function.
5602 * blockframe.c: remake cache_pc_function_* static.
5603 * dbxread.c (symbol_file_command): remove references to
5604 cache_pc_function_* variables.
5605 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
5606 * printcmd.c: Avoid kludging a global variable (addressprint)
5607 to avoid printing the address of a string twice. Instead,
5608 pass the format letter 's' down low enough that it can be seen
5609 to avoid this problem.
5610 (print_formatted): Pass format arg to value_print.
5611 (restore_addressprint): Remove function.
5612 (do_examine): Avoid hacking addressprint, cleanups and such.
5613 (print_frame_args): Add a comment to a Bothner change.
5614 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
5615 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
5616 to wipe out the values cached in blockframe.c.
5617 * symtab.c (find_method): Add comment saying how big you must
5618 allocate to be "big enough". Per being terse again.
5619 * valprint.c (val_print): Handle format letter "s" to print
5620 strings without addresses. Add comment to vtbl printing code
5621 which casts with wild abandon. Rearrange reference-printing
5623 @0xaddr: value (print w/addressprint)
5624 value (print w/~addressprint)
5625 @0xaddr (parameter lists w/addressprint)
5626 or nothing (parameter lists w/o addressprint)
5628 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
5630 * Merge more changes from Per Bothner:
5632 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
5633 annoying) that I tried to improve it. Here are my suggestions.
5635 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
5638 Do automatic de-reference when taking the address of a reference.
5640 Don't deref_ref when printing parameter lists.
5642 More attempts at treating refernences properly.
5644 In val_print, if deref_ref==0, don't print dangling " = ".
5646 Add COERCE_REF macro, which de-references an REF.
5648 * Merge changes from Per Bothner:
5650 * Fixed (Sony news)-specific configuration problems.
5651 * Fixed other problems with using vanilla pcc and libc (enum problems;
5652 assumption that vsprintf exists).
5653 * Some major speed-ups (finc_pc_partial_function now caches a match;
5654 parsing avoids duplicate symbol_lookup calls).
5655 * Changed handling of baseclasses (no longer use baseclasses field
5656 of struct type, use the first n_baseclasses fields instead).
5657 * Various minor changes/fixes, most C++-related.
5660 Cache the most previous match from find_pc_partial_function.
5661 (Save both low and high ends of matching function's pc range.)
5662 This speeds up the loop of infrun.c:wait_for_inferior quite
5663 a bit, and makes step/next commands much zippier.
5665 Added an enum->int cast (otherwise, some compilers barf).
5667 No longer set baseclass offset to 0, since multiple
5668 inheritance now mostly works.
5669 Added a number of casts, to shut up compiler warnings
5670 (after stabs where made enums, not ints).
5671 When discarding a symbol table (in symbol_file_command),
5672 must clear the cache introduced in blockframe.c.
5673 Don't convert $vtbl_ptr_type to vtbl any more.
5674 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
5675 Mask off sign bit emitted by g++ for virtual table offset.
5676 Set voffset to -1 (not 1) for static member functions.
5678 Changed parsing/lexing of names to avoid doing symbol lookup twice
5679 (once when lexing to determine symbol class, once for real).
5680 Now only call symbol_lookup once. Fields of 'this' win especially big.
5682 Subpress printing addr twice in the case of 'x/s addr'.
5684 lookup_basetype_type is no longer used.
5685 Add find_methods as recursive helper function to decode_line_1.
5686 This allows multiple inheritance to work.
5687 Also, once one or more matches has been found, do not look in
5688 base-classes. (Baseclass methods would be overridden, anyway.)
5690 Removed baseclasses array in struct type.
5691 Instead of using baseclasses[i], use fields[i-1].
5692 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
5693 Changed sign convention of voffset (previous was inconsistent).
5695 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
5697 Used to assume existence of vsprintf. Re-written to not need it
5698 if HAVE_VPRINTF is undefined.
5700 typecmp was too pessimistic. Made it less so.
5702 Don't print space after address.
5703 If vtable points to a misc symbol (with 0 offset), print it,
5704 since that indicates the actual class of the object.
5705 Changed ype_print_derivation_info to use new inheritance
5706 scheme (without baseclasses vector).
5708 In value_primitive_field, fixed some bugs left over from previous set of fixes.
5709 Also, changes needed because TYPE_BASECLASSES were removed.
5711 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
5713 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
5716 If there is no path set, and the symbols don't indicate what directory
5717 a file was compiled in, look in the current directory. But either
5718 a path or a known compilation directory will prevent this.
5721 Three independent bug fixes:
5722 * Remove the #if 0 block that breaks some stuff.
5723 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
5724 adapt gdb to either SunOS 4.0.* or 4.1.
5725 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
5728 Instantiate the class T when looking for methods in it. (Tiemann@sun)
5731 (type_print) Demangle the name being printed.
5732 (type_print_base) Handle botched demangling without coredump (tiemann).
5735 (check_stub_method): Document routine.
5736 (tiemann) fix bug for no-arg functions
5737 Avoid clobbering beyond end of malloc'd storage.
5738 Terminate the argument list properly.
5740 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
5742 * Changes merged by John Gilmore:
5745 In breakpoint_1, use new print_address_symbolic instead
5746 of find_pc_partial_function. (This forces use of assembler-level
5747 addresses, and avoids misleading non-mangled source-level names.)
5749 Generalize ansi argument such that -1 means skip arglist totally.
5750 Removed global variable print_ansi_qualifiers (which made
5751 code non-reentrant), in favor of extra explicit arguments
5752 to internal routines.
5754 Add new helper function print_address_symbolic.
5755 Use find_pc_misc_function instead of find_pc_partial_function
5756 (since we want assembler-level symbols here).
5758 Print unknown function as just "f (...)", not "f (...) (...)".
5759 Use new fputs_demangled explicitly.
5761 Fixed a typing violation (problem: value.h cannot be imported
5762 without renaming many variable in this file).
5763 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
5764 decode_line_1: Moved forward some never-reached code.
5765 Made decode_line_2 skip function prologues correctly.
5767 fputs_filtered should not demangle by default.
5768 Add new fputs_demangled to demangle on demand..
5770 Change value_struct_elt to use value_primitive_field (using recursive
5771 utility function search_struct_field). This allows foo.bar to work
5772 for multiple inheritance (so far only for data fields).
5773 Change check_field in the same way (recursive helper function
5774 to support multiple inheritance).
5775 (Note: there are more of these problems that I haven't fixed.
5776 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
5777 value_of_this: 'this' symbol name is now just "this", note "$this".
5779 Don't print static members.
5780 Avoid printing "members of <type>" if there are none.
5781 Simplified type_print_derivation_info by merging duplicate code.
5782 Remove useless blank lines in type_print_base (ptype command).
5784 Added declaration of new routine value_primitive_field.
5786 Added value_primitive_field which is generalized version of
5787 value_field that can handle multiple inheritance (non-zero offsets etc).
5788 Re-implemented value_field to call value_primitive_field.
5790 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
5792 * infcmd.c -- insert else to avoid 'delete env' coredump when you
5793 delete the whole environment. Karl Berry reported the bug.
5794 * source.c - fix openp to avoid //'s in filenames, which
5795 trigger an Emacs bug causing it to not be able to find files
5796 when running gdb in a window.
5797 * dbxread.c - zap the #if 0 that botches the add-file code.
5798 It seems to work a lot better without all the code commented out.
5800 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
5802 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
5805 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
5807 * Makefile - added a ${CFLAGS} to a couple of entries,
5808 added remote-sa.sparc.c
5809 * added remote.sa-sparc.c, a modification of remote.c
5810 which conducts a dialog directly with the SparcStation prom.
5811 * breakpoint.c, infrun.c, sparcdep.c added
5812 remote_insert_breakpoint(), and remote_remove_breakpoint()
5813 to breakpoint.c instead of directly writing breakpoint instructions.
5814 * sparcdep.c on remote_debugging,there is no need
5815 to remove signle step breakpoint instructions.
5816 * main.c added "-epoch" flag and "int epoch_interface" to main.c
5818 * printcmd.c - epoch interface sends lisp expressions to open up
5819 epoch windows on inspection.
5820 * valprint.c - added arrayprint, and addressprint and made adding
5821 format controls easier
5822 * wait.h added a couple of undef's because we were getting
5823 complaints about WSTOPSIG and WTERMSIG begin redefined.
5826 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
5828 * symtab.c (decode_line_1): Add support for handling method stubs
5829 in the type information.
5831 Tue Jul 3 09:39:18 1990 Michael Tiemann (tiemann at masham)
5833 * values.c (baseclass_addr): Run loop from INDEX+1 to
5834 N_BASECLASSES; otherwise, we can still get into a loop.
5835 @@ This should be restructured to use a cleaner search strategy.
5837 Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
5839 * dbxread.c (define_symbol,read_type): Grok GNU C++'s new
5840 abbreviation "Tt" for tags which have the same name as their
5843 Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham)
5845 * symtab.c (list_symbols): add ability to set breakpoints on all
5846 the functions which match a particular regular expression.
5848 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
5850 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
5851 should print ANSI qualifiers (such as `const' and `volatile').
5852 All callers changed to call with ANSI == 1, except from
5853 `check_method_stub', which uses old-style syntax.
5855 * symseg.h (struct fn_field): Remove unneccessary `args' field.
5856 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
5858 * values.c (check_stub_method): New function.
5860 * cplus-dem.c (do_type): Handle "long long" (encoded as 'x').
5862 * dbxread.c (read_type): Handle new GNU C++ method type stubs.
5863 * valprint (type_print_base): Ditto.
5865 * symtab.c (gdb_mangle_typename): New function.
5867 Tue Jun 5 00:18:43 1990 Michael Tiemann (tiemann at gzilla)
5869 * breakpoint.c (catch_command): New function. Provides a
5870 mechanism to set breakpoints based on catch clauses.
5871 (disable_catch): Similar, but disables breakpoints on catch
5873 (delete_catch): Similar, but deleted breakpoints on catch clauses.
5875 Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla)
5877 * blockframe.c (blockvector_for_pc): New function.
5878 * blockframe.c (block_for_pc): Changed to call
5879 `blockvector_for_pc' and get the block itself.
5881 * stack.c (catch_info): New function. Prints info about
5882 exceptions which can be caught in the current frame.
5883 * stack.c (print_frame_label_vars): New function. Similar to
5884 `print_frame_local_vars'.
5885 * stack.c (print_block_frame_labels): Prints out labels that are
5886 defined in this frame. These labels are exceptions that can be
5889 * dbxread.c: Updated to handle N_CATCH symtab types.
5891 Thu May 3 22:10:00 1990 Michael Tiemann (tiemann at teacake)
5893 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
5894 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
5895 when printing the type.
5897 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)
5899 * valprint.c (val_print): Use `baseclass_addr' to access the
5900 baseclasses pointed to via the derived class object at VALADDR.
5902 * values.c (baseclass_addr): New function. Casts derived pointers
5903 to baseclass pointers taking virtual baseclasses and multiple
5904 inheritance into account.
5906 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5910 Fri May 4 12:12:55 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5912 * breakpoint.c (watch_command, bpstat_stop_status): Deal with
5913 exp_valid_block field correctly.
5915 * infrun.c (wait_for_inferior): When checking "don't even think
5916 about breakpoints" if stop_signal == SIGTRAP && trap_expected,
5917 also check step_resume_breakpoint.
5918 Insert breakpoints and continue (not step) if
5919 step_resume_break_address != NULL, even if another_trap.
5920 If trap_expected and we enter sigtramp, then set up a
5922 If trap_expected is set when we hit the step_resume_break,
5924 When calling resume and trap_expected says tell resume to step
5925 (2 places), also check step_resume_break_address.
5927 * infrun.c (wait_for_inferior): Don't set
5928 prev_{pc,sp,func_{start,name}} before calling wait ().
5929 Do set them after exiting loop.
5930 Move their declarations outside functions.
5931 (start_inferior): Initialize them.
5933 Thu May 3 00:15:11 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5935 * infrun.c (wait_for_inferior, after check for trap_expected > 1):
5936 Restore old code which distinguishes between trap_expected and
5937 running_in_shell, just make the latter take any non-TRAP signal,
5940 * values.c (allocate_value): Zero VALUE_OPTIMIZED_OUT flag.
5942 * Makefile.dist (pinsn.o): Use PINSN_CC to compile.
5943 xconfig/3b1 (CC,PINSN_CC): Define.
5945 * xconfig/altos, altos-dep.c: Rename altos-dep.c to altos-xdep.c.
5949 * breakpoint.c (bpstat_stop_status),
5950 infrun.c (wait_for_inferior) [SHIFT_INST_REGS]: New code.
5952 * param.h, tm-88k.h: Define ADDR_BITS_*.
5953 infcmd.c (jump_command, read_pc), infrun.c (wait_for_inferior),
5954 printcmd.c (do_one_display): Use them.
5956 * utils.c: Split #ifdef USG into a USG_UTILS and a QUEUE_MISSING.
5957 xm-88k.h: Define USG_UTILS.
5959 Wed May 2 00:05:33 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
