3 * infrun.c: When using SVR4 /proc interface instead of ptrace(),
4 call proc_set_exec_trap() to setup child to stop at first instruction.
6 * inftarg.c: When using SVR4 /proc interface, call proc_wait()
9 * m68k-tdep.c: Add new routines supply_gregset(), fill_gregset(),
10 supply_fpregset(), and fill_fpregset(), which are machine
11 dependent support routines for SVR4 /proc interface.
13 * utils.c: Add warning_setup() and warning(). Warning() behaves
14 the same as error() except that it returns normally rather than
15 jumping back to command level. Modules that don't want to call
16 warning() for some reason, but want to produce their own warnings,
17 can call warning_setup() to ensure compatibility with the way
18 warning() and error() deal with the terminal.
20 * symtab.c: Make internal errors produce more useful messages.
22 * tm-68k.h: Move code that is duplicated in almost every single
23 m68k based machine's configuration files to this common file.
24 Duplications in the configuration files still need to be removed
27 * infrun.c (child_create_inferior): System V versions must call
28 setpgrp() with no arguments, to comply with prototyping typically
31 * munch: Add support for SVR4 style nm output.
33 * dbxread.c, mipsread.c symmisc.c, symtab.c: Remove the object
34 file specific fields from the partial symbol table structure and
35 replace them with a pointer to private data for each different
36 flavor of object file reader to initialize appropriately.
38 Tue Oct 22 18:04:32 1991 Stu Grossman (grossman at cygnus.com)
40 * infrun.c (wait_for_inferior): Check return value from
43 Mon Oct 21 17:47:03 1991 Stu Grossman (grossman at cygnus.com)
45 * infrun.c (wait_for_inferior): fix stepi/nexti that was broken
46 by my last edit to this routine.
48 Mon Oct 21 10:04:39 1991 Steve Chamberlain (steve at rtl.cygnus.com)
50 * configure.in: added ebmon target.

56 * Makefile.in: Roll VERSION to 4.2.
57 * README, TODO, WHATS.NEW: Update.
59 * core.c (core_open): Improve error message for bad file.
60 Pass .reg virtual memory address to fetch_core_registers to help
61 it find the registers in the core-file header.
62 * coredep.c (fetch_core_registers): Take new argument, use it,
63 and pass it to register_addr to locate the block of registers.
64 * xm-mips.h: Update KERNEL_U_ADDR for new scheme. Cleanup a bit.
66 * dbxread.c (read_dbx_symtab, process_one_symbol): Handle
67 Sequent N_FN_SEQ like everybody else's N_FN.
69 * main.c: Circumvent SCO cc bug with #if !!defined(USG).
70 * tm-i386v.h: #endif guck.
71 * xconfig/i386*: Remove -Dgetpagesize()=4096 kludge.
72 * xconfig/i386sco: Add HAVE_STRSTR to avoid ANSI bdeath.
73 * xconfig/tahoe: Add REGEX, which seems to be missing.
75 * coredep.c: Add <sys/types.h> for SCOnix.
76 * dbxread.c (read_dbx_symntab): Avoid coredump on malformed file.
77 * printcmd.c (print_formatted): Flush output before disassembly.
79 Tue Oct 15 20:12:32 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
81 * doc/refcard.tex (sec "Working Files"): consistent metavars and
82 other improvements, due to comments by François Pinard
83 (pinard@iro.umontreal.ca)
85 * doc/gdb.texinfo (appendix "Installing GDB"): changes in
86 configure, and improvenets related to Pinard's refcard comments
88 Tue Oct 15 08:45:12 1991 John Gilmore (gnu at cygnus.com)

103 * dbxread.c (read_enum_type): Avoid Modula-2 kludge that breaks C
105 * i387-tdep.c (double_to_i387): Fix typo for double_to_ieee_extended.
106 * utils.c (_initialize_utils): If !ISATTY, don't paginate.
107 * configure.in, tconfig/decstation, xconfig/decstation: Rename
108 dec3100 to decstation.
110 Mon Oct 14 13:37:50 1991 Roland H. Pesch (pesch at cygnus.com)
112 * doc/gdb.texinfo: Catch up to changes recorded here in ChangeLog
113 (nodes Continuing and Stepping; Memory; Targets) clarifications
116 Fri Oct 11 23:27:06 1991 John Gilmore (gnu at cygnus.com)
118 * tm-{irix3,mips,nindy960,pn,symmetry,vx960}.h: Move
119 REGISTER_U_ADDR to corresponding xm- file. Sugg. by Peter Schauer.

138 Wed Oct 9 17:03:34 1991 John Gilmore (gnu at cygnus.com)
140 * mipsread.c, coffread.c: initialise TYPE_VPTR_FIELDNO to -1.
141 This avoids coredumps under `set print object on' in value_headof
142 (called erroneously by value_from_vtable_info) for `p &struct'
143 or `p *struct'. From Peter Schauer.
145 Mon Oct 7 00:06:52 1991 John Gilmore (gnu at cygnus.com)
147 * Makefile.in: Roll version to 4.1.2.
148 * dbxread.c: Use aout64.h, not a.out.gnu.h. Get external symbol entry
149 size from BFD (but, FIXME, we don't yet read external nlists's and
150 convert them to internal nlists's before handling them -- we still
151 assume they have the same size and alignment.) Use SET_NAMESTRING
153 * exec.c (exec_file_command): Move dead coff-encapsulation code
155 * m88k-tdep.c, m88k-xdep.c: Remove encap test and #inc <a.out.h>.

162 Fri Oct 4 17:04:31 1991 Per Bothner (bothner at cygnus.com)
164 More patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
165 * mips-xdep.c (store_inferior_registers): Don't try to
166 write the (pseudo) FP.
167 * mipsread.c (parse_partial_symbols): Improved algorithm for
168 setting pst->texthigh.
170 Fri Oct 4 16:47:32 1991 Roland H. Pesch (pesch at cygnus.com)
172 * doc/Makefile: make TEXINPUTS include . everywhere
174 Fri Oct 4 00:35:56 1991 John Gilmore (gnu at cygnus.com)
176 * coffread.c, dbxread.c, symfile.c, symmisc.c, symtab.h: Remove
177 vestiges of typevectors, which were for symsegs and are no longer
178 used. (From a question by Eliot Dresselhaus
179 <dresselh@RFT30.nas.nasa.gov>).
181 Thu Oct 3 09:33:26 1991 John Gilmore (gnu at cygnus.com)
183 * dbxread.c, coffread.c: static-ize functions that were
184 gratuitiously external. (From Fred Fish.)
186 * c-exp.y: sym->class to SYMBOL_CLASS (sym).
188 * dbxread.c (dbx_lookup_type): Keep doubling size of typevector
189 until it is large enough.
191 * dbxread.c (read_type): Handle error case slightly better.
192 Make complaint message not C++-specific.
194 Wed Oct 2 17:21:07 1991 Stu Grossman (grossman at cygnus.com)
196 * infrun.c (wait_for_inferior): Fix step/next so that you only
197 stop at the beginning of a new line. This fixes various problems
198 with for loops, nested if-else's and switch statements.
200 Tue Oct 1 06:33:55 1991 John Gilmore (gnu at cygnus.com)
202 * symtab.c (lookup_symtab_1, lookup_symbol): "fatal" errors
203 between symtabs and psymtabs become ordinary error()s.
205 * dbxread.c (read_dbx_symtab): Relocate end_of_text_addr
206 properly, making "end pc" correct in shared lib psymtabs.
207 (From Guy Harris <guy@auspex.com>.)
209 Mon Sep 30 13:15:31 1991 John Gilmore (gnu at cygnus.com)
211 * dbxread.c: Enable, but soften, const_vol_complaint.
212 (read_dbx_symtab): N_STSYM and N_LCSYM define static vars.
213 Ditto Gould N_NBSTS and N_NBLCS. Also, all types in the psymtab
214 should be file-scope, not global.
215 (read_struct_type): Remove ancient multiple-inheritance warning.
216 (read_range_type): Check base type, complain & patch if undefined.
217 * stack.c (frame_info): Demangle the function name in `info stack'.
220 Sat Sep 28 10:02:33 1991 John Gilmore (gnu at cygnus.com)
222 * eval.c (evaluate_subexp_for_address): Don't use
223 TYPE_POINTER_TYPE directly (it might be zero if this type has
224 never had a pointer created before); use lookup_pointer_type.
225 * symtab.c (lookup_method_type): Arguments were swapped in all
226 callers, so fix it here. I'm amazed this worked at all!
228 Fri Sep 27 18:09:31 1991 John Gilmore (gnu at cygnus.com)
230 * c-exp.y, m2-exp.y: Define more yysymbols that happen to be
231 "bss" rather than "data" symbols, but which still conflict.
234 * coffread.c (coff_symfile_read): Use xmalloc, not malloc.
235 * core.c (core_files_info): Shorten output.
236 * exec.c (exec_files_info): Ditto.
237 (build_section_table): Ignore zero-length sections.
238 * language.c, printcmd.c: Lint.
239 * language.h (get_frame_language): Declare.

251 * nindy-tdep.c (nindy_frame_chain_valid): Use lookup_misc_func.
252 (Reported by Mark Peek <mark@imagen.com>.)
254 * solib.c (solib_map_sections): Relocate all sections, even
255 though only the text section's size is tracked. Mark ld_text
256 for eventual elimination as we generalize to N sections.
258 * infrun.c (wait_for_inferior): Don't check if the PC is in a
259 call_dummy if we were stopped by a random signal that is being
260 passed to the program. This produced wierd results when calling
261 functions in the inferior and signals (e.g. SIGALRM) were in use.
263 Tue Sep 24 18:05:30 1991 John Gilmore (gnu at cygnus.com)
265 * infrun.c (IN_SIGTRAMP): Not parenthesized properly.
266 Bugfix from Paul Eggert <eggert@twinsun.com>.
267 * tm-ultra3.h (IN_SIGTRAMP): Ditto.
268 * valprint.c (print_floating): Print 9 digits for IEEE floats.

282 * language.c (set_language_command): Print useful help message,
283 and restore the language string after giving help.
284 * valprint.c (typedef_print): Print typedef in C or M2.
285 * symtab.c (list_symbols): Use it.
286 * main.c (main): Avoid any output before (gdb) prompt when -q.
287 * language.c (set_language_command): Handle errors by restoring
288 the language string to its current state (fix from A. Beers).
289 * doc/gdbint.texinfo: Roll in information from README. Rearrange
290 "how to install" and "how to print the doc" stuff so it drops
292 * configure.in: Rename rtpc CPU to romp to match config.sub.
293 * README, WHATS.NEW, TODO: Update for gdb-4.1.
295 Fri Sep 20 17:39:14 1991 Roland H. Pesch (pesch at cygnus.com)
297 * doc/gdb.texinfo: Updates from ChangeLog. set/show write,
298 autoloading shared libs, copyright etc on GDB startup, clean up $_
299 and $__ index refs, set/show listsize and related updates to list
300 cmd. New host/target configs.
302 Fri Sep 20 15:46:00 1991 Roland H. Pesch (pesch at cygnus.com)
304 * doc/Makefile: generate aux version-no file doc/gdbVN.m4
305 from main Makefile.in version definition
306 doc/gdb.texinfo: use version recorded in doc/gdbVN.m4 for current
308 Makefile.in (setup-to-dist): generate doc/gdbVN.m4
310 * doc/gdb.texinfo: merge new language-switching and lang-specific
313 Fri Sep 20 15:00:57 1991 Per Bothner (bothner at cygnus.com)
315 * mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
316 compilers (which may lack stddef.h).
318 Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com)
320 * dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and
321 N_WARNING are the same except for the N_EXT bit, so just use their
322 values alone, rather than OR-ing them with N_EXT.
324 Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com)
326 * mipsread.c (parse_lines): Deal with negative extended line
329 * c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid
330 global symbol conflicts.
332 Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
334 * .gdbinit: Move 'set complaints' to top, so it runs even in
335 case we aren't debugging GDB.
336 * language.c (_initialize_language): Fix type check and range
337 check documentation strings.
338 * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
339 language.c can use it. (Though language.c should really not be
340 handling warnings/errors the way it does, FIXME.)
341 * symtab.c (lookup_primitive_type): const lint.
343 Bugfix from Peter Schauer:
344 * source.c (lines_to_list): Make signed, to avoid comparison
345 going unsigned and complaining that -3 is too high for 21 lines.
346 * stack.c (lines_to_list): Ditto.
348 Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
350 * Makefile.in (HFILES): Add minimon.h.
351 (VERSION): Roll version number to 4.0.95.
352 (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
353 New rules for building distributions. Normal distribution
354 is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
355 one level up from here; it calls make-proto-gdb.dir to build a
356 directory `proto-gdb' which is an image of the release. The old
357 `gdb.tar.Z' rule still works too.
358 * config.sub, configure: Roll in latest from ..
360 Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
362 * doc/gdbint.texinfo: Reorder contents; reorganize new-host,
363 new-target, and new-config chapters; fix minor typos; come closer
364 to usual GNU markup conventions for @file @samp @code @var.

368 Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
369 * mipsread.c (parse_partial_symbols): Enter the name of all
370 structs/unions... into the psymtab so we can access them if the
371 symtab is not read in.
372 * mips-tdep.c: Remove some unneeded #includes.
373 * xconfig/dec3100: Add HAVE_STRSTR.
375 Thu Sep 19 15:14:23 1991 John Gilmore (gnu at cygnus.com)

381 * mipsread.c (_initialize_mipsread): Avoid using
382 builtin_type_void at initialize time.

484 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
486 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
487 entries are enclosed herein. Not all of these changes
488 have been merged into the master GDB sources -- check the
489 ChangeLog above here for the merge log.
491 Mon Jun 3 17:05:45 EDT 1991
493 m2-exp.y Created. Tested outside of GDB for a few days. Proper
494 operators were added, C specific operators and tokens
495 removed. yylex() revamped to some extent. Still things
496 missing from the grammar, such as sets.
497 Tested for two weeks in GDB v3.5.
499 Tue Jun 11 17:23:48 EDT 1991
501 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
502 so they are built-in. Sort of a hack.
504 Fri Jun 14 12:53:51 EDT 1991
506 m2-exp.y Added range checking for numeric constants. Any numeric
507 constant is assumed to be of builtin type INTEGER unless:
508 (1) it is octal or hexadecimal, in which case it is a
509 CARDINAL; (2) it is too big to fit into an INTEGER, in
510 which case it is a CARDINAL.
511 eval.c Added simple range checking for +, -, and * on integers.
512 Doesn't work very well for *, since 6 * 1,000,000,000 =
513 1,705,032,704, which fails the simple test of result >=
514 first_operand, no matter in what order the operands are.
516 Tue Jun 18 14:11:30 EDT 1991
518 Broke the parser into parts, one containing the C grammar and the other
519 containing code to be shared by all of the grammars.
521 The following files no longer exist:
526 The following files were added:
528 c-exp.y (The C grammar)
529 m2-exp.y (The Modula-2 grammar)
530 parser-code.c (Code that is shared by the above grammar)
534 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
535 now necessary to use the Bison compiler compiler, since it
536 will generate function/variable prefixes other than yy.
538 Tue Jun 18 16:47:49 EDT 1991
540 symtab.[ch] Added the external variable working_lang, than holds the
541 value of the current working language.
542 Added the ennumerated type language_mode, with the values
543 language_auto and language_manual, the former meaning that
544 GDB sets working_lang as needed, and the latter meaning
545 that the value of working_lang is totally under user
547 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
548 REAL, BOOLEAN and CHAR. Also added the type codes
549 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
550 utils.c Added set_language_command and show_language_command to
551 implement the GDB support commands "set language" and
553 expression.h A number of identifiers were added to the type exp_opcode
554 to facilitate Modula-2 builtin functions, integer
555 division, and array indexing.
557 Wed Jun 19 13:25:58 EDT 1991
559 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
560 if the language specified by working_lang requires the use
561 of strict typing of expressions. Eventually, even this
562 will be able to be changed by the user.
563 Added the macro RANGE_CHECK, which evaluates to non-zero
564 if the language specified by working_lang requires the
565 checking of a value against the domain of its type.
566 Eventually, even this will be able to be changed by the
568 language.[ch] Predicates involving types (simple_type, ordered_type,
569 same_type, integral_type, numeric_type, character_type,
570 boolean_type, float_type) are added. These predicates are
571 based on the current value of working_lang, and are handy
574 Wed Jun 19 15:39:34 EDT 1991
576 eval.c Added the function type_array_rank which computes the rank
578 valarith.c Added the funtion value_bool, which when given a integer
579 value.h value (ie. struct value *) as an argument, it returns a
580 boolean value (ie. struct value *) true if that integer
581 is non-zero, and a boolean value false otherwise.
582 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
583 will print out properly.
585 Wed Jun 19 16:36:34 EDT 1991
587 valops.c Added the function value_capitalize, which returns it
588 value.h argument capitalized if its argument is a lowercase
589 letter, or the argument unchanged if its argument is not a
591 valarith.c Added the function range_check_p, which returns non-zero
592 value.h if its value argument is between the integral bounds upper
594 Added the function range_check_enum_p, which makes sure
595 that its value argument is a valid member of the domain of
597 Added the function range_check_range_p, which makes sure
598 its value argument lies between the upper and lower bounds
599 of its type argument, which must be a ranged type.
600 Added the function check_array_index, which range and type
601 checks an index of an array.
602 Added the function value_multi_subscript, which computes
603 array[idx1,idx2...idxN], given a value array and an array
604 of values representing indicies.
605 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
606 unpack_long to work with TYPE_CODE_BOOL and
609 Wed Jun 19 18:04:08 EDT 1991
611 symtab.c Stored pervasive types in a structure and make
612 lookup_pervasive_type() a lookup function that was based
613 on working_lang. If lookup_pervasive_type() returned
614 non-zero, then that value was returned (a fix, since
615 before it simply wouldn't return the pervasive type.)
616 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
617 non-zero if the language specified by working_lang means
618 "conversion" when it says "cast".
619 valops.c Added the function value_real_cast(), which performs a
620 value.h *cast*, not a *conversion*, which is what value_cast()
621 does when it can. In particular,
622 value_cast(<float_type>,4) = 4.0, while
623 value_real_cast(<float_type>,4) = some mess.
624 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
625 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
626 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
627 and MIN on integral types. *NOTE*: These are currently
628 hardcoded to work only if there are 8 bits per storage
630 eval.c Made logical functions call value_bool to return a
631 properly typed boolean value, based on working_lang.
633 Thu Jun 20 11:55:27 EDT 1991
635 valprint.c Types now print out in a Modula-2 fashion. This works for
636 the cases when the type is printed out step-by-step, that
637 is, it doesn't work when the name of a structured type
638 (which includes the keyword "struct", etc.) is simply
640 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
641 since type specifications in C and Modula-2 are very
642 different. The C printing of a type is very recursive,
643 whereas in Modula-2 it is generally very simple. C has
644 type prefixes and suffixes, which have no real analogue in
645 Modula-2. Maybe type_print() should call a language
646 specific type printer. This is also advantageous if we
647 compile GDB to exclude some of the languages. We'll just
648 leave those functions out.
650 Thu Jun 20 16:57:10 EDT 1991
652 dbxread.c When reading the complete symbol table in (via
653 psymtab_to_symtab()), the number and types of function
654 arguments are added to a function type. define_symbol()
655 calls add_param_to_type() to accomplish this.
656 Assumption: when we come across a function definition
657 (N_FUN symbol with an 'f' or 'F' in the name), its
658 arguments will appear before another function definition.
659 When a function is found, a pointer to its type is placed
660 in the global in_function_type. Changes that
661 add_param_to_type() makes are to this global.
662 valprint.c The type of a function now includes (for Modula-2) the
663 types of its parameters.
664 eval.c Type checking and a check for the proper number of
665 arguments is now done for function calls. Not sure of the
666 impact this has on C++ member function yet.
668 Thu Jun 20 19:58:48 EDT 1991
670 valprint.c Rewrote the type printer. Broke it into two language
671 specific parts, adding the functions type_print_m2() and
673 An unfortunate consequence is this: if you debugging a C
674 program in Modula-2 mode (why?), info types does not work
675 well with regular expressions, since the types are printed
676 out in Modula-2 terminology, but stored in C terminology.
677 language.[ch] Added the functions new_type_last(), type_keyword(), and
678 type_sep() to aid in the printing of typedefs.
679 symtab.c Made the printing of typedefs as language independent as
680 possible through calls to new_type_last(), type_keyword(),
683 Fri Jun 21 11:50:26 EDT 1991
685 dbxread.c Check all incoming ennumerated types. If it looks like
686 Modula-2's BOOLEAN type, then change the type_code of the
687 type to TYPE_CODE_BOOL so we can process it as a boolean
689 valprint.c Replaced some of the 0x%x with calls to sprintf and
690 hexformat() in val_print().
691 language.[ch] Added the function hex_to_string(), which converts its
692 integral argument to a hexadecimal number (format is
693 language based) and returns the result as a string.
695 Mon Jun 24 12:25:07 EDT 1991
697 valprint.c Some functions call type_print_1() directly, instead of
698 value.h using type_print(), so they can specify where (column) to
699 print things. Since type_print() takes care of language
700 dependence, that needs to be called first. Added a
701 parameter depth to type_print() (so it is now like
702 type_print_1). Changed type_print to type_print_at, and
703 made type_print a macro that passes a depth argument of
705 symmisc.c Changed all calls to type_print_1 to calls to
707 Makefile.dist Made it possible to build GDB for a specific set of
708 depend languages. Do this by passing a definition for the macro
709 LANGS to make. LANGS should be a string containing a
710 space-separated list of language names (ie. LANGS="c m2").
711 The default is to build all languages. Note that grammar
712 files must follow the naming convention of <lang>-exp.y.
713 gdb.lang This holds the current value of the LANGS macro. It is
714 examined every time make is called, and is updated if
716 eval.c Added #ifdef _LANG_<lang> to these files.
717 expread.c Still need to add them to dbxread.c and coffread.c.
725 Mon Jun 24 16:33:11 EDT 1991
727 language.[ch] Added the functions hexformat_pre() and
728 hex_to_string_pre(), which take a prefix argument to
729 include in the format string. Thus, hexformat_pre("08") will
730 return "0x08x" (if the working language is language_c).
731 Made hexformat() and hex_to_string() calls to the above
732 with "" as the prefix argument.
734 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
735 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
736 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
737 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
738 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
739 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
740 valprint.c, vax-pinsn.c
742 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
743 calls to hexformat() and hex_to_string(). Format strings without
744 the leading "0x" were ignored.
746 depend Updated to take the above into account.
749 Tue Jun 25 15:27:18 EDT 1991
751 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
752 and type_check_t to keep track of the current state of
753 range and type checking.
754 main.c Added the variables range_mode, range_check, type_mode,
755 and type_check to record the current state of range and
756 type checking. Added initialization code to main().
757 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
761 Tue Jun 25 17:57:08 EDT 1991
763 dbxread.c process_one_symbol() updates the variable (enum language)
764 source_lang based on the extension of the filename
765 contained in the N_SO sybmol that started this symtab.
766 When end_symtab() is called, the value of source_lang is
767 put into the language field.
768 stack.c select_frame() sets working_lang (and possibly type_check
769 and range_check) to the language field of the symtab
770 associated with the frame that is selected if working_mode
771 is language_auto. If working_mode is language_manual, a
772 warning is printed and working_lang is not set.
773 language.c Added the function set_type_range(), which sets the value of
774 type_check and range_check (if their modes call for
775 automatic setting) based on the current value of
776 working_lang. A non-zero argument will cause the current
777 settings to be output.
780 Wed Jun 26 14:51:40 EDT 1991
782 eval.c Added range checks on assignment.
783 m2-exp.y Added the grammar for sets to the language. Currently,
784 these do not do anything except print an error message.
786 Wed Jun 26 17:01:04 EDT 1991
788 m2-exp.y Added the ability for parse_number() to parse negative
789 numbers. A global flag is set upon encountering a unary
790 minus. This was done to make, for example, 1 parse as a
791 CARDINAL, and not as an integer, per Wirth's examples in
792 Programming in Modula-2 ed.4.
793 valprint.c Added support for "set radix 2" by then setting
794 output_format to 't'.
795 eval.c Implemented range checking on subrange types. Added calls
796 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
797 Implemented MIN and MAX for ennumerated types. The
798 minimum value of an ennumerated type is defined by Wirth
799 as the first identifier, and the maximum as the last.
800 m2-exp.y Made octal numbers ending with "B" be characters and those
801 ending with "C" be numbers, per Wirth's book. (p. 34)
803 Thu Jun 27 14:11:52 EDT 1991
805 stack.c select_frame() now only sets working_lang, it does not
806 notify the user. If working_mode is language_manual, then
807 a warning is issued once.
808 main.c At the end of each call to execute_command(), working_lang
809 is checked against the local static (enum language)
810 current. If they differ and working_mode is
811 language_auto, the new settings of language, type and
812 range checking are printed out.
813 stack.c Modified frame_info() to include the language of the
814 current frame in the output of "info frame".
815 language.[ch] Added the function language_str() which returns the name
816 of the current language.
818 Fri Jun 28 15:33:14 EDT 1991
820 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
821 the language. INCL and DECL currently cause an error,
822 since sets are not implemented yet. INC and DEC are
823 implemented as PREINCREMENT/PREDECREMENT with one
824 argument, and as ASSIGN_MODIFY with two arguments.
825 eval.c Added type checking to the above cases.
826 value.h Added not_lval_constant to the lval_type ennumerated type.
827 not_lval_constant means that the value is a constant
828 value; that is 3 or 'a' or TRUE, not as in a constant
829 identifier. This is used to help coerce numbers such as 3
830 to either signed or unsigned numbers.
831 valops.c Added the function value_coerce_constants() which coerces
832 constant integers as following: if one is a constant and
833 the other is not, the constant's type is set to the type
834 of the other argument. If both are constants and one is
835 signed, the other is converted to a signed constant.
837 Sat Jun 29 17:26:29 EDT 1991
839 valarith.c Added a better range checker. It now checks range
840 (successfully) on integral operations [+-] (signed and
841 unsigned) for any C sized type. Still does not work well
843 int_in_size() returns an integer that is coerced to fit into
844 specified number of bytes.
846 Mon Jul 1 13:04:14 EDT 1991
848 language.[ch] Added the function binop_result_type(), which returns the
849 builtin (struct type *) type that would be the result of a
850 binop on the two values V1 and V2.
852 Wed Jul 3 19:22:53 EDT 1991
854 source.c Extended source_info() to include the source language in
855 the output from "info source".
857 Fri Jul 5 13:48:52 EDT 1991
859 utils.c Moved the support functions for the GDB set/show commands
860 dealing with language into language.c.
861 language.c Added the function language_info(), which displays info
862 about the current working language, type and range check
863 settings. Called via the GDB command "info language".
864 Added an initialization routine _initialize_language(),
865 that sets defaults for the language, type and range
866 variables and sets up the new GDB commands.
867 main.c Language setup moved to language.c.
870 Mon Jul 8 10:10:22 EDT 1991
872 valarith.c Debugged the range checker for arithmetic. Still does not
873 work for multiplication very well.
875 Mon Jul 8 12:40:37 EDT 1991
877 language.[ch] Added the function value_true() which returns non-zero if
878 its argument represents a boolean true value.
879 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
880 check the truth of an expression.
882 Thu Jul 11 12:51:34 EDT 1991
884 language.[ch] Added the predicate structured_type(), which returns
885 non-zero if the argument is a structured type.
886 Added the predicate pointer_type(), which returns non-zero
887 if the argument is a pointer type.
888 eval.c Added the ability to do addition and substraction on
889 pointers and integers. This case simply bypasses the
892 Thu Jul 11 14:41:42 EDT 1991
895 Added the symbol N_DEFD (0x4a) which is a definition
896 module dependency that is used by the GNU Modula-2
897 compiler and the linker. It is not important to GDB,
898 except that [dbx|coff|mips]read.c should ignore these
901 Fri Jul 12 16:07:00 EDT 1991
903 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
904 0 in val_print(). Also added statements to the else part
905 to coerce type (argument to val_print) to a pointer type
906 if it is an "array of unspecified length".
907 valops.c Added the function value_m2_string(), which returns a
908 (value) value which is a constant string, whose type is
909 (ARRAY [0..n] OF CHAR). The length field of the type
910 structure is set to zero, so it will be interpreted as an
911 "array of unspecified length".
912 stack.c Moved the language/frame mismatch check to
913 main.c:execute_command().
914 main.c The working language is recorded each time
915 execute_command() is executed. If working lang has
916 changed during its execution, then the new
917 language/type/range info is printed out for the user. If
918 the working language does not match the language of the
919 frame, a warning is issued.
921 Sat Jul 13 16:16:39 EDT 1991
923 eval.c Moved all the type-checking stuff for operators to
924 language.[ch] language.c. This is so we can keep language-specific
925 stuff (like for what type operators are defined) in
927 language.[ch] Added the function binop_type_check(), which checks to see
928 if its two (value) arguments are type-compatible with its
929 opcode argument. The opcode should represent an operation
930 involving an operator. Also added the macro function
931 unop_type_check, which calls binop_type_check with a
932 NULL second argument.
933 expprint.c Added Modula-2 operators to the op_print_tab, so info
934 expression.h break works correctly. Also added "op_string", which
935 returns the string corresponding to the (enum exp_opcode)
936 opcode that is its argument.
939 Sat Jul 13 18:26:18 EDT 1991
941 coffread.c Added code to record the type of function arguments with
942 each paricular function. Code is very similar to that
944 dbxread.c Moved add_param_to_type() to symtab.c
945 symtab.[ch] Added function add_param_to_type() from dbxread.c
947 *** NOTE: The above additions have not been tested.
949 Mon Jul 15 12:50:47 EDT 1991
951 langauge.[ch] Added the functions type_error and range_error, which work
952 like error() except if the type/range mode is set to
953 *_mode_warn, then they do not do a return_to_top_level(),
954 but merely print a warning.
955 Also changed [set|show]_[type|range]_command() to support
956 the new "warn" feature.
958 Thu Jul 18 17:50:54 EDT 1991
960 mipsread.c Added code to record the type of function arguments with
961 each particular function. Code is very similar to that
964 *** NOTE: The above additions have not been tested.
966 Fri Jul 19 11:19:10 EDT 1991
968 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
969 UMIN_OF_SIZE, which when given a size of a numeric type,
970 return the maximum and minimum value it can hold. UMAX...
971 and UMIN... return the result for unsigned types.
972 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
973 struct types. They call above macros.
974 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
975 avoid a name conlict with the above.
976 c-exp.y Added range checking on numeric constants in
977 parse_number() for completeness.
978 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
979 return 0 if working_lang is not language_c.
981 Thu Aug 8 14:17:22 EDT 1991
985 breakpoint.c Documentation strings of some commands changed to
986 eliminate the references to the C language where
989 Tue Aug 13 15:48:03 EDT 1991
991 m2-exp.y Added qualified identifiers to the grammar. The semantics
992 are slightly different from those of the GDB operator ::
994 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
995 type_exp, where type_exp is any valid type expression.
997 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
998 printcmd.c Modified ptype_command() so it actually parses the input
999 (necessary for type expressions with scope qualifiers).
1000 Added the function ptype_eval() which expects an
1001 expression composed of one OP_TYPE element.
1002 *.[ch] Replaced all occurences of parse_c_expression with
1004 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1

1049 variables and set them based on the exec file.
1050 * am29k-tdep.c: declare text_start.
1051 * valops.c (call_function_by_hand): declare text_end.
1053 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
1054 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
1055 because machines that do this will also have to know to
1056 set NEED_TEXT_START_END. Besides, it was a redundant way to
1058 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
1059 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
1060 NEED_TEXT_START_END.
1062 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
1064 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
1066 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
1067 Pass MUNCH_DEFINE to munch whenever we run it.
1068 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
1069 format string; use 0x%x instead.
1070 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
1071 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
1072 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
1073 * inflow.c: Handle `short' process group IDs.
1074 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
1075 and check for ptrace errors.
1076 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
1077 (coff_symfile_init): Initialize text_bfd_scnum.
1078 (read_coff_symtab): Use it to find the text [and absolute?] sections.
1079 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
1080 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
1081 Merge target arm case with other "easy" cases. Add target
1082 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
1083 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
1085 * minimon.h, remote-adapt.c, remote-mm.c: Add.
1086 * munch: Cope with RT/PC putting fns in data segment.
1087 Restore ability to override `nm' by specifying MUNCH_NM.
1088 * xconfig/rtbsd, xconfig/ultra3: New host systems.
1089 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
1090 and remote-adapt. Remove encapsulated coff #define's (the
1091 support should go in BFD, and gdb shouldn't know or care).
1092 * tconfig/a29k-kern: Same, but for remote kernel debugging.
1093 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
1094 * tm-29k.h: Update BADMAG (though it should go away).
1095 Allow the register definitions to be overridden in another
1096 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
1097 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
1098 DUMMY_SAVE_GR96, for handling kernel calling conventions
1099 that use GR64+ rather than GR96+.
1100 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
1101 remote debugging of Ultra3 kernel. Includes tm-29k.h and
1102 overrides various things.
1104 * remote-mm.c (mm_attach, mm_wait): Handle attach like
1105 child_attach does, making a clean stop in the newly attached
1107 * remote-eb.c: Lint.
1109 * coffread.c: Make coffread independent of any particular
1110 variant of COFF. Avoid #include-ing any particular one except
1111 internalcoff.h. BFD now passes key values for symbol reading
1112 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
1113 and the symbol masks and shifts); use them.
1114 Remove obsolete end_of_text_addr.
1116 * exec.c: Remove unused include files.
1118 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1120 * Makefile.in (documentation targets): Pass $(M4).
1121 Bugfix from eggert@twinsun.com (Paul Eggert).
1123 * stack.c (down_silently_command): Check for stack existence.
1125 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1127 * Makefile.in (VERSION): Update to 4.0.3.
1129 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1131 * core.c (core_file_command): Print frame at coredump with
1132 its level number, by calling print_stack_frame.
1133 * frame.h: Add selected_frame_level, print_stack_frame.
1134 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
1135 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
1136 Change print_sel_frame and print_selected_frame callers to
1139 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
1140 * symfile.c (free_named_symtabs): Ditto.
1141 * main.c (main): wrap_here needs an arg.
1142 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
1143 (solib_add): Avoid noise.
1144 (solib_create_inferior_hook): Lint.
1145 (sharedlibrary_command): Move dont_repeat to here.
1146 * utils.c (error): Call wrap_here to force buffered output.
1148 Small patches from Peter Schauer:
1150 * coffread.c (start_symtab): Free any existing line_vector before
1152 (read_coff_symtab): Ditto for type_vector.
1154 * source.c (lines_to_list): New variable, replacing function.
1155 (all uses): Use as variable.
1156 (_initialize_source): Add 'set listsize' and 'show listsize'.
1157 * utils.c (lines_to_list): Remove function.
1158 * stack.c (print_frame_info): Use as variable.
1159 * defs.h (lines_to_list): Remove declaration.
1161 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1163 * breakpoint.c (insert_breakpoints): Restore warning about
1164 the program might be running in another process, but only for
1165 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
1166 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
1168 * utils.c (error): if error_pre_print is set, print the string
1170 * main.c (main, print_gnu_advertisement, print_gdb_version):
1171 Reformat legalese so it always prints, but acts as an "I'm here"
1172 message while symbols are being read. If any errors occur,
1173 print a few newlines to set off the message and start it at the
1174 left margin. Remove mention of "help" command, and don't yak
1175 about symbol reading.
1176 (catch_errors): Error string is now printed first in case of
1178 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
1179 suggest the "help" command.
1181 * Makefile.in (VERSION): Set to 4.0.2.
1183 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
1185 * .gdbinit: Remove useless "rr" command. Set complaints
1186 to 1 for people debugging gdb.
1188 * breakpoint.c, remote-vx.c: Reword strings printed by
1189 catch_errors callers.
1191 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
1193 * WHATS.NEW: "history write -> history save". Doc "write on/off".
1194 (Fix from kenc@viewlogic.com.)
1196 Fix some infrastructure to be able to cope with host and target
1197 machines with different sized basic types (ints, ptrs, etc).
1198 (Idea from pierre@la.tce.com (Pierre Willard).)
1200 * values.c (value_from_longest): Rename from value_from_long.
1201 Handle pointer types as well as integers, so that targets with
1202 different pointer sizes from the host can be accomodated.
1203 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
1204 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
1205 uses of value_from_long to value_from_longest.
1206 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
1207 the correct pointer type to value_from_long{est}.
1209 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
1211 * remote-vx.c: Remove obsolete code for calling functions via
1212 vxworks kludge interface (it referenced value_from_long).
1214 * valops.c (value_string): Find malloc with lookup_misc_func, not
1217 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1219 Make writing to files work properly. (Fixes to BFD are also needed.)
1221 * core.c (core_open): Open file ourselves, read or r/w, depending on
1222 write_files. Use bfd_fdopenr.
1223 * gdbcore.h (write_files): New variable.
1224 * exec.c (write_files): Define variable, add set&show for it.
1225 (exec_file_command): Use write_files to open for read or r/write.
1227 Make shared library reading happen automatically. These changes
1228 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
1230 * inferior.h (stop_soon_quietly): Add to exported variables.
1231 * infrun.c (child_create_inferior): call solib hook, if defined.
1232 (child_attach): call solib hook, if defined.
1233 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
1234 (find_solib): Use lookup_misc_func rather than hand-rolled.
1235 (symbol_add_stub): New stub for catch_errors.
1236 (solib_add): Avoid output if !from_tty. Catch errors rather
1237 than just calling symbol_file_add and bombing.
1238 (solib_create_inferior_hook): Interface with the target process
1239 to let it read and alloc shared libs, then figure out what it did.
1241 * core.c (validate_files): Fix typo, soften warning.
1242 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
1244 * utils.c (fputs_demangled): Avoid duplicate printing if
1245 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
1247 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
1248 (Fix from pierre@la.tce.com (Pierre Willard).)
1250 * main.c (catch_errors): Change argument to a char * from an int,
1251 since a char * can point to a struct full of glop, but an int
1252 is not guaranteed to be able to hold a pointer.
1253 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
1254 breakpoint_re_set_one, breakpoint_re_set): Adapt.
1255 * core.c (core_open, solib_add_stub): Adapt.
1256 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
1258 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1260 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
1261 by adding .NOEXPORT target.
1263 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1267 * Makefile.in (VERSION): Roll to 4.0.
1268 (gdb.tar.Z): Make refcard.ps as well, for shipment.
1270 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1272 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
1275 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
1278 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
1280 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
1281 reflect above name change
1283 * WHATS.NEW: correct pointer to refcard.
1285 * doc/gdb.texinfo: update New Features, Installing
1287 * doc/gdbint.texinfo: add short description of configure +template
1289 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1291 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
1293 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
1295 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
1296 tar file, add dependencies for referenced doc files.
1298 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
1300 * coffread.c, symfile.c, stack.c: saberized.
1302 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1304 * doc/refcard.tex: permuted Essential Commands sec
1306 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
1308 set/show symbol-reloading
1309 default set complaints 0
1311 RET-repeat disabled after prompted long displays
1312 processID (attach) interpretation of 2nd GDB cmdline arg
1314 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
1316 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
1317 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
1318 breakpoint.c, main.c: lint.
1320 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1322 Install new configuration scheme for GDB and friends.
1324 * config.sub: Translate ordinary names to three-part names.
1325 * configure: Use three-part names internally.
1326 * configure.in: Translate three-part names to filenames.
1328 * README, WHATS.NEW: Update for gdb-4.0.
1329 * Makefile.in: Roll VERSION to 3.99.
1331 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
1333 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
1334 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
1335 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
1336 to single structures rather than arrays; when passing
1337 their address, use &. This avoids trouble with bdead compilers.
1338 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
1339 instead. This avoids portability headaches.
1340 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
1342 * source.c (open_source_file): Avoid ANSI const bdeath by
1343 skipping declaration and then casting result value.
1344 * tm-hp300bsd.h: Clarify comment.
1345 * utils.c (strstr): Result is const char *; ANSI bdeath.
1346 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
1347 since system include file defines it differently from "defs.h",
1348 though the two are equivalent for our purposes.
1349 * tconfig/hp300bsd: Add m68k-tdep.o.
1351 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1353 * tconfig/sun*4: Remove warnings about system assembler.
1355 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1357 * mcheck.c: Avoid warning about undeclared abort fn.
1358 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
1359 it causes recursive calls to error() when used in cleanups.
1360 To do so requires that we make it a function, so we do.
1361 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
1362 * utils.c (do_cleanups): Remove the current cleanup from the
1363 chain *before* calling it, in case error() is called from it.
1364 The result won't be pretty, but won't be an infinite loop either.
1366 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
1368 * dbxread.c (read_struct_type): Grok anon structs for C++.
1369 (vb_name, vptr_name): Null terminate these strings.
1371 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1373 Minor bug fixes from BSD Net2 gdb:
1375 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
1376 returns 0, there is no previous frame.
1377 * breakpoint.c (commands_command): If !from_tty, don't call
1378 input_from_terminal_p().
1379 * dbxread.c (record_misc_function): Speed up slightly.
1380 (compare_psymbols): Ditto.
1381 * infcmd.c (do_registers_info): Take a second argument to
1382 determine whether to print float registers. "info registers"
1383 does not do so anymore. "info all-registers" does, now.
1384 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
1386 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
1387 * inflow.c (initialize_inflow): Set tflags_ours correctly.
1391 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
1392 executing_breakpoint_commands if we are interrupted by error.
1393 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
1394 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
1395 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
1396 catch_errors() so we can setup the frame regardless of whether
1397 the shared libs work.
1398 * ieee-float.c (double_to_ieee_extended): Get exponent from
1399 right place in little-endian systems. From John Carey.
1401 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1403 * main.c: Remove unused terminating_signals and catch_termination().
1404 (long_options): Terminate with a zero element.
1405 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
1406 (gdb_readline): Make call-compatible with readline.
1407 (init_signals): Improve comments re vfork vs. signal.
1409 * utils.c (prompt_for_continue): Use new gdb_readline().
1410 If we prompt for continuation, we don't let CR repeat the previous
1411 command, once we get back to a prompt. It's too easy to keep
1412 hitting CR, expecting "--more--" prompts, and have some long
1413 command start repeating on you.
1415 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1417 * blockframe.c (frameless_look_for_prologue): Speed up by
1418 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
1419 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
1420 Define two variants, one faster.
1421 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
1422 and return zero, rather than giving an error.
1423 (setup_arbitrary_frame): Initialize the PC in the new frame.
1424 (skip_prologue): Add a second arg saying whether we're just
1425 checking for a frameless function or not.
1427 * core.c (core_open, core_close, core_xfer_memory): Move
1428 section table pointers and bfd* into the target_ops.
1429 (core_open): Allow errors in shared lib reading, etc.
1430 (core_files_info): Describe shared library sections.
1432 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
1433 exec_files_info, set_section_command): Move section table
1434 pointers and bfd* into the target_ops.
1435 (add_to_section_table): Add BFD to section table.
1437 * target.c (target_xfer_memory, target_info): Pass target to
1438 xfer_memory and target_info functions.
1441 * gdbcore.h: Move struct section_table.
1442 * target.h: New home of struct section_table.
1444 * solib.c (solib_add): New argument is the target_ops whose
1445 section list is to be added to, if any. Reallocate the
1446 sections in that target to add any that come from shared libs.
1447 (throughout) so_sections renamed to sections.
1448 (solib_xfer_memory): Deleted.
1449 * tm-sunos.h (SOLIB_ADD): Add target argument.
1450 (SOLIB_XFER_MEMORY): Delete.
1452 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1453 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
1454 from target_ops. It's the same on all targets. Add two section
1455 pointers to target_ops.
1457 * stack.c (find_relative_frame): Dump ancient algorithm for
1458 "down", just use handy "next" pointers.
1459 (frame_command): Don't error if there is no stack; let user
1462 * inflow.c (new_tty_prefork, new_tty): New prefork routine
1463 modifies static state in the parent process; new_tty itself
1464 runs in the child and modifies the child's file descriptors
1465 to match the saved static state.
1466 * infrun.c (child_create_inferior): Call new_tty_prefork,
1469 * infptrace.c (child_xfer_memory): Add ignored target arg.
1470 * remote-eb.c (eb_xfer_inferior_memory): ''
1471 * remote-nindy.c (nindy_xfer_inferior_memory): ''
1472 * remote-vx.c (vx_xfer_memory): ''
1473 * remote.c (remote_xfer_memory): ''. Rename from
1474 remote_xfer_inferior_memory.
1476 * main.c (main): Only try to attach "corefile" argument if
1477 it starts with a digit.
1479 * symfile.c (symbol_reloading): New "set/show" variable.
1480 (symbol_file_add): Shorten message about symbol reading.
1481 (add_symbol_file_command): Merge with add_syms_addr_command,
1482 since this should work on all targets now.
1483 (stop_whining): Default to zero, to shut up complaints
1484 about bad symbol tables on many systems.
1485 (free_named_symtabs): Just exit unless symbol_reloading.
1487 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
1488 and add comment explaining shared library screw.
1490 * source.c: #if defined => #ifdef.
1492 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1494 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
1496 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1498 * doc/rdl-apps.texinfo: provide default readline-appendix finder
1499 (doc/Makefile knows how to make one for local config)
1501 * Makefile.in: use doc/Makefile for doc targets
1503 * doc/Makefile: GDB documentation now has its own Makefile
1504 doc/refcard.tex: renamed from "gdbrc.tex"
1505 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
1506 doc/gdbint.texinfo: add markup in "Cleanups" chapter
1509 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1511 * values.c (baseclass_addr): When reading target memory, use the
1512 length of the basetype, not the upper type. We've only malloc'd
1513 enough space for the basetype, leading to errors in free().
1515 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
1516 ends up as a function specially, since we know the actual type of
1517 the pointed-to address. This (somewhat) fixes display of
1518 expressions that include misc_function_vector names. Try `cond 1
1519 !strcmp("a","b")' then `i b'.
1521 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
1522 The child can be proceeded from inside wait_for_inferior in
1523 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
1524 getting skipped in that case.
1526 * expprint.c (print_subexp): Use filtered output, since the
1527 subroutines we call use it, otherwise the output is horribly
1528 mangled, since output of wrappable stuff comes out late.
1530 * Makefile.in: Bump VERSION to 3.98.1
1532 * infrun.c (child_create_process): Use execlp to find the
1533 shell to exec our target program. This requires some fiddling
1534 with `environ' since there is no execlpe().
1536 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1538 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
1539 Minor rearrangement of refcard permits two new make targets--
1540 gdbrc.dvi DVI output for refcard, using CM fonts
1541 gdbrc.ps PostScript refcard, using PS fonts
1543 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1547 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
1548 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
1550 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1552 * doc/gdb.texinfo: last changes for release.
1553 Minor typo and formatting fixes; incorporated most fixes remaining from
1554 filed mail commenting on earlier drafts.
1556 Added warnings: pipes don't work in run command;
1557 conditions are converse of assertions;
1558 step over fn without debug info goes to next fn;
1559 vars may have "wrong" values near fn entrance, exit
1561 Added example from Kingston on printing repeated nonadjacent values
1563 Added explicit mention that in Emacs gdb mode C-c and C-z are like
1564 shell mode for signals
1566 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
1567 doesn't sound so much like its parent "Stopping and Continuing"; also
1568 moved entries on continue to top of section, so they don't get lost.
1570 Improved installation directions in appendix, added manual formatting
1573 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1575 * configure.in: Remove xm.h and tm.h even if we aren't linking
1576 new ones, so "./configure sun4; ./configure none" does the right
1577 thing. Assume that alldeps.mak and depend are already built in
1578 srcdir, and avoid running "make" (particularly "make depend",
1579 which involves "gcc") from inside configure. Build Makefile
1580 directly rather than building Makefile.conf first.
1581 * configure: Regenerate with above changes.
1582 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
1583 to 3.98. Revise gdb.tar.Z procedure to produce a file
1584 called gdb-$(VERSION).tar.Z but which unpacks into a
1585 directory called "gdb". Move non-source files out of
1586 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
1587 (depend): Don't try to do "gcc expread.y".
1588 (expread.o): Update dependencies by hand.
1590 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1593 Fixed a variety of small typos that prevented info from formatting
1594 cleanly; altered too-long heading for GPL Appendix, as discussed
1595 w/RMS; Changed date on cover to July 91.
1597 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1600 (1) Applied some fixes due to comments from Larry Breed (easier ones
1601 through chapsec 5.2)
1602 (2) Eliminated use of @footnote---had my doubts about it anyways, and
1603 it's broken in latest texinfo
1604 (3) Introduced *some* use of [] for optional arguments, where
1605 explanation is not simpler by listing cmd w arg and cmd w/out arg
1606 separately. Still not using @deffn.
1607 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
1608 couple of headings are too long. Need patches to texinfo or revision
1611 * Partial update to README (which still needs work for this
1612 release!): (1) use of configure corrected for new script,
1613 (2) "make gdb.dvi" and "make gdb.info" mentioned.
1615 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
1617 * symtab.c (lookup_symbol): Don't complain right off about
1618 no debug symbols; use the misc function vector first.
1619 (list_symbols): Use misc function vector to find symbols
1620 that don't have debug info, and print them.
1621 (find_pc_symtab): Temporarily avoid fatal() when psymtab
1622 PC range doesn't match symtab PC range, as it does on the
1623 MIPS because our symtab reading isn't perfect.
1625 * dbxread.c (dbx_symfile_read): Make warning about
1626 "no debug symbols" slightly nicer.
1628 * source.c (select_source_symtab): If "main" symbol exists,
1629 but decode_line_spec can't find line info, don't just return
1630 a zero; try other source symtabs or give an error.
1632 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
1633 their low addresses first, then rip through fixing high addrs.
1635 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
1636 <runene@ifi.uio.no>.
1637 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
1639 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1641 * Minor, mostly mechanical, cleanup of doc subdir for clean
1642 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
1643 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
1645 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
1647 Mostly MIPS and general symbol-reading fixups.
1649 * doc/gdbint.texinfo: Add documentation on symbol-reading
1652 * mipsread.c: Remove kludges around #include "ecoff.h".
1653 Remove redefinitions of a_magic, etc, no longer used.
1654 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
1655 Fix global overview comments to match symfile.c protocol.
1656 (mipscoff_new_init): Eliminate cur_hdr if we have one.
1657 (mipscoff_symfile_read): Eliminate unused code. Avoid
1658 sorting all the symtabs, when all we have read here is psymtabs.
1659 The symtabs are sorted as they are created anyway. Tell
1660 condense_misc_bunches whether we're mainline.
1661 (psymtab_to_symtab_1): Pass filename when recursing, to make
1662 stack trace more informative.
1663 (parse_partial_symbols): Assume cur_hdr as argument.
1664 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
1665 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
1666 the TYPE_NAME of char *, since that's done in symfile.c.
1667 (free_numargs, parse_symbol, add_symbol, add_block,
1668 shrink_linetable): Declare these fns void.
1669 (upgrade_type): Convert tree of if's to switch. Clean up
1670 bogus "off == 0" handling with a complaint. Avoid setting
1671 field bitpos and bitsize of array with lower and upper bounds.
1672 Check specified bitsize of elements against their actual type's
1673 bitsize, and complain if different. Complain about unknown
1675 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
1676 (psymtab_to_symtab_1): Print names of subsidiary files that
1677 are being read in. FIXME, we read far too many files. This code
1678 is not the problem, the problem is in parse_fdr where the psymtabs
1680 (cross_ref): Result should indicate that we used one aux entry
1681 normally, or two if we encountered a "next" entry. This used
1682 to leave the caller pointing at the wrong aux entry.
1683 (add_symbol): If overflowed cur_block, reallocate it larger,
1684 chase all pointers to it, and complain(), rather than clobber memory.
1685 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
1686 (new_field): Only allocate one field initially, not two.
1687 Pull ++ out of macro argument. Simplify.
1688 (_initialize_mipsread): Avoid initialization of importd
1689 global_psymbols and static_psymbols.
1691 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
1692 to properly set pst->symtab; avoid searching for it.
1693 (symfile_fns): Improve comments, add a FIXME.
1694 * dbxread.c: Update comments to reflect symfile protocol.
1695 (read_ofile_symtab, end_symtab): Return the symtab.
1696 (psymtab_to_symtab_1): Set pst->symtab.
1698 * coffread.c (coff_symfile_read): tell condense_misc_bunches
1699 whether we're mainline.
1701 * symfile.h (sym_fns): Remove unused sym_discard member.
1702 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
1704 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
1705 the environment variable is not.
1706 * infcmd.c (finish_command): Use filtered printfs.
1707 * cplus-dem.c: Add struct tags to a few unnamed structs.
1708 * valops.c (value_coerce_array): Improve comments.
1709 * valprint.c (type_print_varspec_suffix): Print array size only
1710 if greater than zero.
1711 * m88k-tdep.c: Shift some lines left by one space, that had
1712 apparently been trashed at some point.
1713 * TODO: More things to do, a few got done.
1715 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1717 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
1718 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
1720 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
1721 * expread.y, findvar.c, symmisc.c: Ditto.
1722 * printcmd.c (address_info): Update printed forms of LOC_
1723 symbols. Elim LOC_EXTERNAL.
1724 (print_frame_args): Keep track of param stack offsets before
1725 re-looking up to find the local register param is kept in.
1727 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
1728 Further integration of mipsread into gdb. Eliminate unused
1729 routines, duplicate declarations. Handle static symbols in
1730 psymtabs as well as external symbols. When reading symtabs,
1731 insert symbols into the correct block (global, static, or a local
1733 (read_mips_symtab, parse_partial_symbols): Don't pass useless
1735 (mipscoff_symfile_read): Don't call select_source_symtab.
1736 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
1737 rather than SYMBOL_VALUE.
1738 (parse_external): Comment clobbering of top_stack.
1739 (parse_partial_symbols): Update comments. Allocate and parse
1740 static symbols as well as external symbols. FIXME, enum values
1741 are not handled in this pass, but should be. Inline new_psymbol.
1742 Use SYMBOL_VALUE_ADDRESS.
1743 (psymtab_to_symtab_1): Read symbols into global static block
1744 by default (until enter some function's local block context).
1745 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
1746 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
1748 * source.c (select_source_symtab): Select a source symtab
1749 from either the symtabs or, failing that, the psymtabs.
1750 (list_command): Update error message.
1751 (forward_search_command, reverse_search_command): Use getc, not
1752 fgetc, for speed. FIXME, add comment about buffers that die if
1753 overrun by long line.
1755 * values.c (unpack_field_as_long, modify_field): Avoid shifting
1756 by an entire word, which is not portable, if we have a 32-bit
1757 field. (Code in dbxread.c already turns such bitfields, if
1758 aligned, into ordinary ints, but fixing this will help for other
1759 symbol formats and for future changes.)
1760 * core.c (core_open): Handle ANSI const brain death.
1761 * utils.c (vprintf): Fix varargs typo.
1763 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1765 * findvar.c (find_var_value): Handle &function better.
1766 * TODO: Document work needed on &fn and &array.
1767 * printcmd.c (print_address_symbolic): New arg is the prefix
1768 to print if a name is printed.
1769 (print_address_demangle): Honor "set print address" now.
1770 Use new arg above to improve spacing of output.
1771 * valprint.c (val_print): When printing function pointers,
1772 print symbolic form too.
1773 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
1775 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1777 * core.c (memory_error): Reword error msg to mislead less.
1779 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
1781 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
1782 parse_partial_symbols): Use newer BFD internals (external_filehdr
1783 and external_aouthdr), byte-swap the fields that we care about
1784 before using them, and make the file header data local to
1785 read_the_mips_symtab rather than global.
1787 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
1789 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
1790 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
1792 * main.c (command_line_input): Flush stdout and stderr
1793 before every call to readline. This reportedly fixes a bug
1794 that comes up in Sys V running emacs-gdb and/or xxgdb,
1795 when stdin/out are pipes or sockets.
1797 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1799 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
1800 Avoid declaring Makefile dependencies, because GNU Make stupidly
1801 tries to update it if we do.
1803 * coffread.c: Revise for minor changes to bfd internal coff
1806 * configure: If -template= is given a relative path, make it
1807 absolute before recurring in subdirectories.
1809 * configure, configure.in, Makefile.in: Install "configure" script
1810 as replacement for config.gdb.
1811 * config.gdb, Makefile.dist, Makefile.sdir: Remove
1812 * README: Update for configure, mostly. FIXME.
1814 * Add dec3100 as equivalent to littlemips. Indicate in all host &
1815 target config files that they are for the host. When the lines
1816 get copied into the Makefile, this makes it more obvious what's
1819 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1821 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
1822 tabs, which end up in the disassembler output inadvertently.
1824 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1826 Make it compile cleanly in an ANSI GCC2 environment.
1828 * blockframe.c: <stdio.h>
1829 * cplus-dem.c: free takes a void *, ifdef __STDC__
1830 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
1832 * defs.h (alloca): Avoid doing anything if alloca already def'd.
1833 * stddef.h, stdlib.h: Remove these files.
1834 * symtab.c: Avoid declaring qsort, close.
1835 * symfile.c: Avoid declaring close.
1836 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
1837 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
1839 Assorted other changes.
1840 * dbxread.c: include "libaout.h", not "liba.out.h".
1841 * printcmd.c (print_frame_args): Set recurse properly for
1842 indentation of struct and array parameters.
1843 * valops.c (value_cast): Allow cast to void.
1844 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
1845 single_step() in a target-independent fashion.
1846 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
1847 set up to be ready to continue. This makes us target independent.
1848 * infptrace.c (child_resume): Remove call to single_step; now
1849 can single step a SPARC target of any kind.
1851 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1853 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
1854 docn into separate sections---basically chapters, plus two loose
1855 pieces that can be configured to go in different places. This
1856 allows GNU m4 to preprocess the manual without coredumping.
1858 * Makefile.dist: tell TeX where to find texinfo.
1860 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1862 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
1863 the new target "rdl-apps.texinfo" which captures the Makefile
1864 variable that records where to find the Readline libraries.
1866 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
1868 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
1869 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
1870 * defs.h (const, volatile): Only define if not already defined.
1871 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
1873 * README: Update for release 3.95.
1874 * config.gdb: Don't create readline dir in subdir builds.
1875 * main.c: Include with "..." form for non-system include files,
1876 so "gcc -MM" for "make depend" works.
1877 Include readline files with "...h" rather than <readline/...h>.
1878 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
1880 * coffread.c: Undo minor damage done by Rich Pixley. Use
1881 different internal and external representations of COFF
1882 data structures. Use new BFD routines for swapping them in and
1884 * symfile.c (free_named_symtabs): Avoid freeing file names that
1885 are null or empty. Old i960 tools seem to produce files that
1886 claim to have empty names, causing each successive file read
1887 to blow away the previous one.
1888 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
1889 Move deferred_stores to top of file, but don't separate its
1890 #define's from its variable. Add commentary.
1891 * Makefile.dist: Fix Rich damage; undo "configure" changes in
1892 favor of keeping the (working) config.gdb. Move readline
1895 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
1897 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
1899 * infptrace.c (fetch_registers): no result, since now void.
1900 * tconfig/news: target depends on m68k-tdep too.
1902 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1904 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
1907 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
1908 applied various small fixes due to or inspired by RMS comments
1910 * doc/gdb.texinfo: finished using all RMS comments, save those for
1911 appendices on readline and cmd history (which are in other source
1914 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1916 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
1917 chapter 9; (2) documented 'break' command's menu mode for
1918 overloaded names, in response to hgs problem report C++ p-31
1920 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1922 * doc/gdb.texinfo: (1) better introductory example; (2) more
1923 consistent use of @code, @samp, @file, @kbd throughout; small
1924 cleanups to first three nodes; (3) new "Contributors" node;
1925 (4) Appendix, Renamed Commands; (5) divert specialized startup
1926 instructions to "Targets" chapter for generic manuals, while
1927 leaving them up front for manuals specific to specialized
1928 environments; (6) apply fixes from RMS comments through chapter 4.
1930 * pretex.m4: modify explanatory text slightly (and redefine
1931 "regexp") to keep GNU m4 from complaining. (It still crashes
1932 later, but one step at a time...)
1934 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
1936 * readline/readline.c (update_line): Avoid dereferencing a pointer
1937 before comparing it to its bounds. Saber caught this.
1938 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
1939 and only set PC if tgetstr returned non-null. Saber caught this.
1941 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1943 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
1944 stuff for config manual) here where it counts; updated
1945 to use new subdir structure (gdb/doc/).
1947 * Makefile: generated from above via
1951 * gdbint.texinfo: added instructions on generating gdb.info* files
1952 locally for release. These are ordinary info
1953 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
1954 Makefile)---but due to use of texinfo 2, can't count on makeinfo
1955 to generate these, so we distribute them already formatted.
1957 * gdb.texinfo: included full Info node and menu crud (as generated
1958 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
1960 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
1961 put in comments-for-future gdb.info target (one day makeinfo will
1964 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1966 * gdb.texinfo: Updated to include new or old undocumented
1967 commands, at least the following (perhaps some others I forgot to
1968 record): info f, info float, info path, info program, info s, info
1969 set, info source, info terminal, info types, info user, set/show
1971 Also covered all recent GDB command renames for v4.
1973 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1975 * mipsread.c: Rather than keeping count of how many symtabs
1976 and psymtabs we have, for sorting purposes, count them when
1977 we need to sort. This fixes bug in rereading of symbol tables.
1979 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1981 * infcmd.c: renamed "info path" to "show paths"
1982 * gdbrc.tex: documented above.
1984 Wed May 8 04:51:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1986 * remote.c: Fix comments.

2455 * coffread.c (SDB_TYPE): New macro.
2456 various: Use it instead of checking against T_NULL.
2458 * Makefile.dist (cplus-dem.o): Hack in an #include "param.h"
2459 before we compile it.
2460 defs.h: Protect against multiple inclusion.
2461 param.h: Include defs.h.
2462 signame.c: Change #ifdef SYS_SIGLIST_MISSING to #if.
2463 param-no-tm.h: Define SYS_SIGLIST_MISSING from USG.
2465 Thu Apr 18 19:49:10 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
2467 * i386-pinsn.c (OP_E): Change %d to 0x%x for consistency.
2469 * putenv.c: New file
2470 Makefile.dist: Add it to $(OBS).
2472 * mipsread.c [!CMUCS]: #include <syms.h>.
2474 * mips-xdep.c (fetch_core_registers): #if 0 out the whole function.
2476 * Move read_memory_nobpt from mem-break.c to breakpoint.c.

2480 * utils.c (_initialize_utils): Rename "set demangle" to
2481 "set print demangle", "set asm-demangle" to "set print
2482 asm-demangle" and "set sevenbit-strings" to "set print

2502 Rename "set arrayprint" to "set print array".
2503 Rename "set array-max" to "set print elements".
2504 Rename "set prettyprint" to "set print pretty".

2514 Sun Apr 14 23:08:34 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
2516 * inftarg.c (child_open), remote-vx{,.68}.c (vx_proc_open):
2517 New function to give correct error message.
2519 Thu Apr 11 17:19:41 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
2521 * target.h: Add to_doc and target_preopen.
2522 target.c: Add target_preopen and target_command.
2524 (add_target): Call add_cmd and mess with targetlist->doc.
2525 core.c, exec.c, remote-eb.c, remote-nindy.c, remote-vx.c,
2526 remote-vx.68.c, inftarg.c, remote.c: Add doc field to target struct.
2527 Call target_preopen from open routine.
2529 * main.c: Rename editing_info to show_commands.
2530 (_initialize_main): Rename "info editing" to "show commands".
2532 * source.c: Rename directories_info to show_directories.
2533 (_initialize_values): Rename "info directories" to "show directories".

2544 Rename add-syms to add-symbol-file.
2546 Thu Apr 18 18:08:30 1991 John Gilmore (gnu at cygint.cygnus.com)
2548 * symfile.h (free_named_symtabs): Rename from free_named_symtab.
2549 * symfile.c (clear_symtab_users_once, cashier_psymtab,
2550 free_named_symtabs): Move these routines from symmisc.c.
2551 * symmisc.c (same): same.
2552 (free_symtab): Make non-static.
2553 * symtab.h (free_symtab): Declare as exported void fn now.
2554 * dbxread.c (end_symtab, end_psymtab): Change comments.
2555 (initialize_dbxread): Call dbx_new_init() in case the first
2556 command is add-symbols.
2557 * target.c (dummy_target): Permit add_syms_addr_command.
2559 Sat Apr 13 14:46:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2561 Permit symbols to be superseded when new symbol files have
2562 been read in, particularly for VxWorks.
2564 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
2565 to the main file, as well as to include files. Also, put global
2566 functions into the global psymtab, to make "i fun" work.
2567 (end_psymtab): Free named symtabs and psymtabs for a file, once a
2568 new psymtab for it has been read.
2569 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
2570 a file, once a new symtab has been read for it.
2571 * mipsread.c: FIXME. We need to do the same for MIPS, but it
2572 looks harder to determine the top-level block before it's been
2573 queued to the psymtab list.
2575 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
2576 If we have wiped out any old symbol tables, clean up at end of
2578 (symbol_file_command): Don't reference symfile_fns if it's zero.
2580 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
2581 defines for the blocks of a blockvector that contain global and
2582 file-static symbols and the first of the smaller scope contours.
2583 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
2584 decode_line_1, make_symbol_completion_list): Use the above.
2585 * coffread.c (end_symtab, patch_opaque_types): Ditto.
2586 * dbxread.c (end_symtab): Ditto.
2587 * expread.y (block): Ditto.
2588 * mipsread.c (throughout): Ditto.
2589 * symmisc.c (free_named_symtabs): Ditto.
2591 * symtab.c (list_symbols): Process the first symbol of the
2592 static psymbols list.
2593 (types_info): Restore this function from its untimely #if 0.
2594 It's not perfect, but it is better than nothing.
2595 (_initialize_symtab): Restore "info types".
2597 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2599 * m68k-stub.c: Remote stub for 680x0's, created from
2600 rem-m68k.shar (which is removed).
2601 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
2602 Remove RCS log stuff now that we use CVS and it blows our diffs.
2604 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2606 * symmisc.c (free_named_symtab): Make it work, in its current
2607 kludgy fashion. Change result to indicate if we blew away bkpts.
2608 * dbxread.c (end_symtab): Accumulate result from
2609 free_named_symtab and print warning if we blew user's state.
2610 * symfile.h: free_named_symtab now returns an int.
2612 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
2614 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
2615 is the first symbol read, even if not mainline.
2616 (dbx_psymtab_to_symtab): symfile might be zero, cope.
2617 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
2618 (set_section_command): New command ("section xxx yyy" -- should
2619 be renamed to "set section xxx yyy" FIXME) which sets the
2620 base address of a section of the exec file, overriding the
2621 virtual address that BFD reports.
2623 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2625 * exec.c: Add add_syms_addr_command to exec_ops, so you can
2626 load symbols at any address while examining an exec file.
2628 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
2630 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
2631 for printing the float info is host-dependent, not
2632 target-dependent. FIXME.
2633 * i386-pinsn.c: Move #includes to top, remove useless ones.
2634 * i386-tdep.c: Don't bother including <.../reg.h> since we
2635 don't use it (and it doesn't exist on host systems).
2637 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
2638 Convert negative numbers properly.
2639 (ieee_test): Make numbers really random; fix format arg.
2641 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
2642 * core.c (core_detach): Unpush core_ops, which might not be on
2643 top. We used to just pop the top, which broke things. Don't
2644 need dont_repeat() any more.
2645 (core_file_command): Psst! Don't repeat it.
2646 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
2647 * expprint.c (print_subexp): Avoid switch fallthru on
2648 BINOP_ASSIGN_MODIFY, so we can print += and such.
2649 * frame.h: Fix typo.
2650 * inflow.c (kill_command): After killing inferior, print our
2651 current frame in the core file, if we have one.
2652 (generic_mourn_inferior): When inferior dies, either select
2653 the current frame (in the new target, e.g. core file), or
2654 set both the current and selected frames to NULL.
2656 Changes from Peter Schauer.
2658 * infptrace.c: Avoid <sys/ptrace.h> on USG.
2660 * Make all file names fit in 14 characters (sigh and damn!):
2661 mv hp300hpux-xdep.c hp300ux-xdep.c
2662 mv symmetry-xdep.c symm-xdep.c
2663 mv symmetry-tdep.c symm-tdep.c
2664 mv convex-opcode.h convx-opcode.h
2665 mv tm-vxworks960.h tm-vx960.h
2666 mv tm-vxworks68.h tm-vx68.h
2667 mv Makefile.srcdir Makefile.sdir
2668 mv gdb-int.texinfo gdbint.texinfo
2669 mv remote-sa.m68k.shar rem-m68k.shar
2670 mv remote-multi.shar rem-multi.shar
2671 * Makefile.dist, README, config.gdb, convex-pinsn.c,
2672 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
2673 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
2676 * command.c (user_info_1, user_info): New command for listing
2677 the user-defined commands.
2679 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
2681 * dbxread.c (really_free_pendings): Clear file_symbols
2682 and global_symbols after freeing them; otherwise, running
2683 this function twice (if it appears twice on the cleanup
2684 chain), we try to free things twice.
2686 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
2687 based on text_addr (the address of text in core), not on addr (the
2688 offset between text in the .o file and in core). This change
2689 is from Peter Schauer.
2691 * main.c: Define ALL_CLEANUPS as a cast of zero.
2692 (return_to_top_level): Use it.
2693 (main): Do all cleanups after each command run as part
2694 of the gdb startup sequence. Also do all cleanups before
2695 entering the command loop, and every time we exit the command
2696 loop and reenter. Before, the cleanups from the startup sequence
2697 were being left undone until the first error!
2698 (command_loop): Rename do_nothing cleanup to command_loop_marker
2699 so we can see it easily when examining the cleanup chain.
2700 (init_signals): Add another do_nothing for signal handling.
2701 (quit_command): Only try to kill target if it has execution.
2702 Problems in the target stack got us into a state where
2703 inferior_pid was nonzero but none of the targets had execution.
2704 In this state you couldn't exit gdb.
2706 * dbxread.c: Two changes from Peter Schauer.
2707 (echo_command): Fflush output after an echo command.
2708 (show_history): Pass all args to cmd_show_list.
2710 * utils.c (init_malloc): Call mtrace to turn on tracing
2711 if the environment variable MALLOC_TRACE is set to a file name.
2712 * mtrace.c: Add source file which provides a log of every malloc,
2713 free, and realloc to a trace file.
2714 * mtrace.awk: Add source file which analyzes the trace file.
2715 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
2716 (VERSION): Roll to 3.94.3.
2718 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
2719 (check_duplicates): Don't bother with watchpoints.
2720 (set_raw_breakpoint): Comment about danger of this routine.
2721 (watch_command): Parse and eval all args before calling
2724 * solib.c (find_solib): Avoid error in referencing memory to
2725 see if any more shared libraries have been added. This is
2726 particularly useful if the target has terminated. Bug reported
2729 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
2730 in bringing up 3.94.2 on the Sun-3.
2732 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
2733 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
2734 expression (in scope) before reenabling watchpoint.
2735 * signame.c (init_sigs): Add missing declaration of i, fix
2736 sys_siglist declaration.
2737 * source.c (list_command): Fixed range computation to use
2739 * stack.c (backtrace_command): Do not allow command if target has
2740 no stack, print informative error message.
2741 * target.c (target_command): Do not write into command line
2742 because this fails if the target command is used in a user defined
2743 command. [This change was enhanced by gnu to support any-
2744 unique-prefix matching on target names.]
2745 * valops.c (value_struct_elt): Avoid infinite loop on an
2746 erroneous attempt to print the member of function (try p main.p).
2748 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
2750 * expread.y (name_no_typename): Avoid reduce/reduce errors
2751 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
2752 Since the GDB parser really doesn't use name_no_typename in a
2753 name-only context, the parser can't tell the diff between
2754 names and numbers here. Avoid allowing a name_no_typename
2755 to be a NAME_OR_*INT to resolve the conflict.
2757 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2759 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
2761 * valprint.c (val_print_fields): bitfield printing didn't handle
2762 byte order. Indirect through a few more fns to cope.
2764 * values.c (modify_field): also cope with byte order.
2766 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2768 Cleanup for release 3.94.2:
2770 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
2771 include files. Roll version to 3.94.2.
2773 * coffread.c (init_stringtab): Read length into unsigned char
2774 array before swapping; don't assume 32-bit longs.
2776 * target.c (target_info): Don't bother with get_sym_file, just use
2777 the symfile global variable.
2778 * symtab.h, symfile.c (get_sym_file): Delete it.
2780 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
2781 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
2782 (read_type): Replace one more error() with complain().
2784 * mipsread.c (parse_partial_symbols): Replace printf with complain.
2786 * i960-tdep.c: Fix copyright attribution.
2788 * config.gdb: Quote all backquotes in doublequotes. You can
2789 quote me on that. BSD 4.4 shell found this one.
2791 * infptrace.c (throughout): The third argument to ptrace is an
2794 * infrun.c (wait_for_inferior): When program has terminated, we
2795 have to call target_terminal_ours before we pop that target off
2796 the stack (e.g. before a call to target_kill or
2797 target_mourn_inferior). This fixes problem where a program
2798 terminates, then GDB stops for (tty output) and you have to type
2799 "fg" to the shell to resume it. FIXME: This code for what to
2800 do after termination really should be in normal_stop instead.
2802 * gdbcore.h (read_memory_check): Change declaration; it changed
2805 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
2806 4.4 prereleases, this avoids a bug in their sgtty compatability
2808 * remote.c: Use terminal.h rather than hand-rolling the same.
2810 * signame.c, signame.h (psignal): Arg is unsigned, not int.
2811 * utils.c (strsave, strstr): Fix arg types.
2812 * valprint.c (val_print): lint
2814 MIPS symbol table support from Per Bothner:
2816 * symfile.c (symtab_fns): Remove initializer table that needs to
2817 be hacked for each new symbol file format supported.
2818 (add_symtab_fns): New function, chains symbol table
2819 handlers into the global list.
2820 (symfile_init): Search this list.
2821 * symfile.h: Add next pointer, declare add_symtab_fns.
2822 * coffread.c (_initialize_coffread): Call add_symtab_fns.
2823 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
2825 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
2826 symbol *). Thus, we no longer need the hack to trash
2827 pst->filename. Good, since that hack confused code in symfile.c!
2829 (reorder_symtabs, destroy_all_symtabs): Removed static
2830 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
2831 Instead, the latter now uses a temporary array (stack-allocated
2832 from an obstack, and then freed).
2834 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
2835 haven't been set in the outermost stBlock of a procedure. This was
2836 a problem with f77 binaries on Ultrix 4.?.
2838 (new_symtab, new_symbol, new_type): Continue changing code to use
2839 obstacks more and otherwise conform to dbxread internal style.
2840 Made the free_code of symtabs be free_linetable (as in dbxread)
2841 instead of free_contents. This implies memory leaks when reading
2842 a new symbol table, until the conversion is finished. Did change
2843 (struct symbol) and (struct type) to be allocated on the
2844 symbol_obstack. Blocks and blockvectors are among the things
2847 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
2848 tested much, but it solved one problem (reported by Meissner), and
2849 cleans up some other things. The problem happened when an
2850 included file contains actual code (functions) and not just
2851 definitions. The mips coff is a little inconvenient there, since
2852 it may cause a procedure to be mapped to the wrong psymtab.
2854 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
2855 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
2856 this will need work for the new core paradigm.
2858 Opcode patches from the net:
2860 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
2861 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
2862 missing altogether - they are added here. From Bruce Bauman.
2863 * mips-opcode.h: The low mask for C0 instructions was too small.
2864 From Garrett Lau. I modified the fix to check the entire 32-bit
2867 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
2870 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2872 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
2874 * dbxread.c (read_type): Pointer subtraction (value_sub in
2875 valarith.c) sometimes failed because the types of the
2876 pointers being subtracted were not identical.
2877 These differed because dbxread.c was allocating pointer types
2878 using dbx_alloc_type+smash_to_pointer_type instead of
2879 lookup_pointer_type. I failed to find a justification for the
2880 former, so I changed it to use the latter. Similarly, I
2881 replaced smash_to_function_type by lookup_function_type,
2882 and smash_to_reference_type by lookup_reference_type.
2884 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
2885 _initialize_mipsread): corresponding changes.
2887 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
2889 * source.c (mod_path): Do tilde_expand on each component of the path,
2890 rather than on the (list of) paths as a whole.
2891 (print_source_lines): Set first_line_listed in addition to
2892 current_source_symtab and current_source_line. If the source was
2893 not findable, after a "dir" command to fix the problem,
2894 a "list" would get the wrong lines.
2896 While I was there... (gnu):
2898 * dbxread.c (read_type): Change error to complaint.
2900 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2902 First attempt at detailed understanding of symbol table memory alloc.
2904 * dbxread.c (dbx_symfile_read): Free our string table if we
2905 aren't the mainline. Free the "info" struct since we're done with
2907 (init_psymbol_list): Free any previously allocated psymbol lists.
2908 (): FIXME: Should realloc-down the psymbol lists when done reading
2909 the main symbol file?
2911 * symmisc.c (free_symtab): Free fullname field too.
2913 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
2914 (REGISTER_ADDR): Make result type unsigned int.
2916 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
2917 define REGEX must also define REGEX1 (its dependency).
2919 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
2921 * tconfig/i960: No longer works, points you at vxworks960 or
2924 * xgdb.c, XGDB-README: Remove file. Users can get the much
2926 * Makefile.dist: Remove all trace of xgdb.
2928 * breakpoint.c (breakpoint_1): Pass demangle arg to
2929 print_address_symbolic.
2930 (clear_breakpoints): Remove unused function.
2931 (breakpoint_re_set_one): Guts of breakpoint_re_set.
2932 (breakpoint_re_set): Use catch_errors to do them all anyway.
2934 * gdb-int.texinfo (Host versus Target): Add section on what is
2935 a "host" feature versus what is a "target" feature.
2937 * infcmd.c (path_command, path_info): Handle the PATH variable
2938 (object search path) as conveniently as the source search path.
2939 * environ.c (set_in_environ): Set some vars in GDB's environment,
2940 in addition to the child's. PATH, G960BASE, G960BIN for starters.
2941 * source.c (mod_path): New function, from guts of
2942 directory_command, modifies a path. Used by path_command.

2953 * infcmd.c (do_registers_info): Print floating point registers
2954 in raw hex as well as float format, regardless of whether it is
2955 a "virtual" convertible register.
2956 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
2957 regs as a double, just in case it's being used that way.
2958 * values.c (unpack_long): Comment on array/function coercion.
2959 (unpack_double): Argument is in target byte order now. For
2960 integer arguments, just call unpack_long and float the result.
2961 * m68k-tdep.c: include defs.h for "const" handling.
2962 * remote-nindy.c: Use ieee-float stuff.
2963 (nindy_fetch_registers): Unpack double regs to host double, then
2965 (nindy_store_registers): Pack extendeds to host double, flip
2966 around by misusing unpack_double, send as target double.

2977 Changes from a bringup on the DEC Vax under Ultrix 4.0.
2979 * coredep.c (fetch_core_registers): Pass end-address of register
2980 section to register_addr as expected. Don't call supply_register
2981 if we'd just pass it garbage.
2983 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
2985 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.

3030 * inftarg.c (child_detach): Pop the child_ops vector if the
3031 detach is successful.
3032 * remote-nindy.c (nindy_create_inferior): Don't push a new
3033 nindy_ops since nindy uses the same one for execution and memory
3035 * core.c (core_ops): Use child_attach and child_create_inferior
3036 rather than default attach and create_inferior functions.
3038 Handle floating point registers in core files.
3040 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
3041 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
3042 This version untested since BFD doesn't yet support sun3 core
3044 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
3045 conventions. Fix comments and style. This version has not
3046 been compiled yet, since we have no HP inhouse.
3047 * core.c (get_core_registers): Look for two sections, ".reg"
3048 and ".reg2", and pass both to fetch_core_registers sequentially.
3050 Revise directory path yet again.
3052 * source.c (forget_cached_source_info): Not static any more.
3053 (init_source_path): New default source path is "$cdir:$cwd".
3054 (dir_command): Handle variable arguments ($cdir, $cwd).
3055 (source_info): Print "Compilation directory" rather than
3056 "Originally compiled in" to remind people of $cdir.
3057 (openp): If the path contains $cwd, use current directory.
3058 (open_source_file): If compilation directory is known, replace
3059 first $cdir in path with the compilation directory.
3060 (print_source_lines): Even if we can't print the lines, set the
3061 current symtab and line for future commands like "info source" or
3062 "breakpoint". Also, error message now contains the file name,
3063 line number, and file access error message.
3064 (_initialize_source): Fix help text to describe changes.
3065 * main.c (cd_command): Forget cached source info when we chdir.
3066 * utils.c (strstr): Add simple implementation.

3070 * coffread.c (read_one_sym, init_linetable, init_stringtab):
3071 Byte-swap COFF symbol tables if necessary when reading them in.
3072 Use complain() to replace error message in one spot. Needs
3073 corresponding change in bfd/coff-code.h to make some symbol
3074 swapping routines non-static.
3076 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3078 Merge changes from Eirik Fuller, for UTek.

3086 declarations of errno.
3088 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
3090 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
3091 <rpc/rpc.h> and <rpc/types.h>.
3093 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
3095 * i960-tdep.c (examine_prologue): Add new argument limit,
3096 which stops the scan at the end of the prologue, or at the PC.
3097 This fixes a problem where it walks down into the code for the
3098 user's statements if that code looks like function prologues.
3099 Mark Fox and I have been bouncing this code back and forth, making
3100 small changes to it. Callers changed to match.
3102 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
3104 Cleanup for gdb-3.94 release final:
3106 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
3107 the .c files from vx-share and nindy-share, from the various
3108 macros, since they are not found via ALLDEPFILES.
3109 (SFILES): Add tm-i960.h.
3110 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
3111 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
3113 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
3114 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.

3118 * am29k-tdep.c: Add contribution line.
3119 (examine_prologue): Cache information about function prologues in
3120 the misc-function-vector to avoid lots of references over the
3121 serial line while examining instructions.
3123 * core.c (core_close): New function made from cleanup_core.
3125 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
3126 remote-vx.c, remote.c, target.c, target.h,
3127 Update target_ops vector to add attach, close, and load entries.
3128 Use add_syms_addr_command, not add_file_addr_command, for
3129 add_file. Break out close routine from existing code.
3131 * dbxread.c (really_free_pendings): Don't free pending_blocks;
3132 they are in an obstack.
3133 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
3135 (define_symbol): Add symbol type parameter; change callers;
3136 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
3137 it to influence the symbol class on the i960.
3138 (define_symbol): Swap LOC_CONST's into target byte order.
3140 * exec.c (exec_close): New function.
3141 (exec_file_command): Call it.
3143 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
3144 Fix byte order of frame pointer.
3145 (read_var_value): Result of 0 if var's value can't be found,
3146 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
3147 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
3148 (locate_var_value): Use read_var_value and use its lazy address
3149 as the location of the var's value. Lint.
3151 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
3154 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
3155 obsolete Intel versions in favor of vxgdb versions.
3156 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
3157 code dealing with byte order of values, which Intel did in host byte
3158 order rather than gdb-4's target byte order.
3159 (i960_frame_chain_valid): Move to nindy-tdep.c.
3160 (examine_prologue, skip_prologue, frame_find_saved_regs,
3161 frame_args_address, leafproc_return, saved_pc_after_call,
3162 pop_frame): Add vxgdb versions from Mark Fox.
3163 (examine_prologue, frame_struct_result_address): Add code
3164 to deal with the saved value of G13 (struct return address
3166 (frame_args_address): Modify Mark's version to prefer the
3167 saved value over the current value in the topmost frame.
3168 Cache result in the frame info to avoid performance hair in
3170 (print_fault): Add gdb960 code for printing faults.
3171 (_initialize_i960): Actually call check_host.
3173 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
3174 add stub routines. FIXME, these currently just return zero!
3176 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
3177 (attach_command): Call target_attach, not target_open, now.
3179 * infrun.c (normal_stop): Make global, not static, for vx_attach.
3180 (child_attach): Rename from child_open.
3181 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
3182 don't confuse it with a zero step_resume_break_address.
3184 * inftarg.c (child_detach): Eliminate inferior_pid test.
3185 (child_files_info): Clean up message a bit.
3186 (child_ops): Use child_attach, not child_open, to attach.
3188 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
3189 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
3190 findvar.c to here, since it depends on the contents of the
3191 shadow_contents of breakpoints, but keep if #if 0 since it is
3194 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
3197 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
3198 (ptype_command, display_command): Eliminate have_inferior_p and
3199 have_core_file_p in favor of target_has_stack or
3200 target_has_execution.
3201 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
3202 code for actually finding the values of arguments, though we still
3203 keep track of the maximum stack offset for use in printing unnamed
3204 arguments. Handle missing FRAME_ARGS_ADDRESS.
3206 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
3207 (struct nindy_regs): Define registers passed to/from nindy.
3208 (nindy_fetch_registers, nindy_store-registers): Translate between
3209 nindy and GDB formats for the registers.
3210 (dcache_init): Statically allocate the cache, since it was being
3211 allocated by a malloc that was never freed anyway.
3212 (nindy_create_inferior): Error, not core dump, if no exec file.
3213 (nindy_before_main_loop): Use target_load, not target_add_file.
3215 * remote-vx.c (net_load): Specify large timeout for load
3216 requests. Allow user to break out with INTERRUPT.
3217 (net_break): Remove useless code, clean up. Change callers.
3218 (parse-args, skip_white_space, find_white_space): Clean up arg
3219 parsing to cope with quoted strings.
3220 (net_wait, net_quit): Never call error, just return status.
3221 (vx_read_register, vx_write_register): Cleanup status checking.
3222 #ifdef the code based on which CPU we are using (960 or 68k),
3223 FIXME, this should be completely general but it isn't yet.
3224 (vx_xfer_memory, vx_resume): Cleanup status checking.
3225 (vx_run_files_info): Improve message.
3226 (vx_load_command): Renamed from vx_add_file_command. Allow load
3228 (net_ptrace): Remove unused routine.
3229 (vx_wait): Adopt code from vxgdb960 to cope with broken
3230 connections to target machine and prompt to disconnect. Remove
3231 debug printouts. Map some EVENT_'s to SIGnals.
3232 (add_symbol_stub, vx_open): Print names of object files we found,
3233 and "ok" if we read their symbols OK. Clarify output in general.
3234 (vx_attach, vx_detach, vx_kill): Add these commands.
3235 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
3236 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
3237 "info files" output, and create_inferior, since we already have
3240 * stack.c (frame_info): Replace Frame_unknown with 0.
3241 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
3242 (return_command): Pop until the PC matches as well as the FP,
3243 so it works even if the FP is shared with another function,
3244 as in "frameless" or "leaf" procedures.
3246 * symfile.c (load_command): renamed from add_file_target_command.
3247 (add_syms_addr_command): renamed from add_file_addr_command.
3248 (add_syms_command): Stub to call target_add_syms.
3249 (_initialize_symfile): Change command names and descriptions,
3250 add-file => add-syms, and load from alias to its own command.
3252 * target.c (kill_or_be_killed, maybe_kill_then_attach,
3253 maybe_kill_then_create_inferior): Default for attempts to start
3254 a process, if one is already running, is to ask about killing
3255 it and retry if yes.
3256 (upstack_create_inferior): #if-0 it, strata obsolete it.
3257 (push_target, unpush_target, pop_target): to_close() a target
3258 before unstacking it.
3259 (target_info): Renamed from target_files_info.
3260 (_initialize_targets): Rename "i files" as "i target", accessible
3263 * target.h: Improve comments about the target_ vectored routines.
3265 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.

3268 (SKIP_PROLOGUE): No longer a no-op.
3269 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
3270 (*_REGNUM): Sort register numbers.
3271 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
3272 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
3273 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
3274 are now 10 byte extendeds, not 8 byte doubles.
3275 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
3276 for nindy versus vxworks targets. FIXME, this should possibly go
3277 in the target vector.
3278 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
3279 frame_saved_regs and arg pointer with each frame.
3280 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
3281 (FRAME_ARGS_ADDRESS): Use cached result.
3282 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
3283 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
3284 (PRINT_RAMDON_SIGNAL): Call print_fault.
3285 (POP_FRAME): Now works.
3287 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
3288 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
3289 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
3290 (ADDITIONAL_OPTION_HANDLER): use target_load, not
3293 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
3294 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
3296 * valarith.c (value_subscripted_rvalue): Avoid handling
3297 floats and doubles specially; it gave alignment errors. Lint.
3299 * valops.c (value_of_variable, value_of_this): Error if unknown
3302 * valprint.c (print_floating): Bcopy rather than pointer-deref,
3303 to avoid alignment problems.
3304 (value_print): Handle unknown value address.
3305 (cplus_val_print): Two args are ignored; remove them. Change caller.
3306 (val_print): Use unpack_long rather than pointer-deref.
3309 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
3310 to avoid alignment problems.
3311 (value_being_returned): Error if return value unknown.
3312 (set_return_value): Add bogosity warning, FIXME. *
3314 * TODO: A woman's work is never done.
3316 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
3317 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
3318 Add ieee-float.o to OBS.
3319 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
3320 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
3321 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
3323 Changes to generalize the VxWorks RPC protocol slightly, to handle
3324 i960 as well as 68000.
3326 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
3327 * vx-share/reg.h: Produce i960 regs #ifdef I80960
3328 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
3329 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
3330 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
3331 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
3332 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
3333 so they will move in target byte order rather than network
3334 byte order (happens to be the same).
3336 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
3338 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
3340 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
3343 Add contribution lines to various files, showing where they
3346 * breakpoint.c (break_insn, check_break_insn_size,
3347 read_memory_nobpt): Remove to mem-break.c.
3349 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
3352 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
3353 entry has bad register number. This change is not
3354 tested in this release, FIXME.
3356 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
3359 * value.h: Force value's contents field to be aligned to hold
3360 at least a double or a long long (if supported). This avoids
3361 doing bcopy's in and out of the contents field.
3363 (step_1): Avoid coredump under obscure circumstances when we
3366 * symtab.h (misc_info): Add field to misc function vector for
3367 any kind of cached information the target code desires. AMD
3368 29000 uses this to avoid repeating examine_function_prologue's.
3370 * coffread.c: Lint. Remove static symfile, read_section_header.
3371 core.c (have_core_file_p): Lint: remove.
3372 expprint.c (print_subexp): Lint.
3373 infptrace.c, valops.c, valprint.c: lint.
3375 Roll in changes from vxgdb-5.0.1:
3377 * symtab.h: Comment byte order of each address class. Add
3378 LOC_LOCAL_ARG for frame-relative args (960).
3379 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
3380 symtab.c, symmisc.c: ditto.
3382 * infrun.c (init_wait_for_inferior): Clear stop_signal.
3384 * remote.c (remote_resume): Error if resume with a signal.
3386 * symfile.c (prim_record_misc_function): Clear misc_info.
3387 (fill_in_vptr_fieldno): Check stub type of arg.
3389 * valops.c (value_cast): Avoid looking up names of types whose
3390 name we don't know, to prevent coredump. Sun CC produces typedef
3391 rtx and the name of *rtx is zero...
3393 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3395 Roll in changes from final AMD 29000 port (Tiemann).
3397 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
3398 for ../include/a.out.encap.h. This might not work now that BFD
3399 is separately compiled. Instead, BFD support for encap will have
3400 to translate machine type 29k into the right COFF_MAGIC.
3402 * infcmd.c: Remove references to inferior_pid that aren't used
3403 in actual ptrace calls; use target_has_execution, etc.
3404 (have_inferior_p): Remove function.
3405 (program_info): Print target info rather than "process number";
3406 avoid gratuitous messages unless from_tty.
3407 (run_stack_dummy, finish_command): Set proceed_to_finish.
3408 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
3409 main.c: Lint. Lose have_inferior_p().
3410 inferior.h (have_inferior_p): Remove, lint.
3411 (proceed_to_finish): Add flag to ask that all regs be saved
3412 by normal_stop, for the few commands that need it, speeding up
3413 serial I/O. Add comments to stop_registers.
3415 * remote-eb.c: Remove newline from breakpoint message we grep
3416 for. Never time out when running the user program.
3420 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3422 Roll in changes from vxgdb-5.0.1:
3424 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
3425 symbol in its raw form, we are processing an unlinked ".o" file.
3426 See if the target environment has assigned it an address, using
3427 target_lookup_symbol (VxWorks does), and enter it into the symtab
3430 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
3431 68k versions for a simpler version that assumes zero FP at bottom.
3432 Fixes bug of truncated stack reports.
3434 * target.h (target_lookup_symbol): Define this routine's args
3435 and result, finally.
3437 * target.c (nosymbol): Default routine for target_lookup_symbol.
3438 (target_default): Default lookup_symbol and call_function too.
3439 (files_info): Only print has_all_memory warning if a non-dummy
3442 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
3443 vx_convert_from_virtual): If target does not have floating point,
3444 zero register "values", and avoid doing cross-net conversions.
3445 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
3446 (vx_open): Rearrange code that attaches to target and reads
3447 symbols for all loaded modules, to work if some of the modules
3448 are not accessible. Add symbol_stub() and add_symbol_stub()
3449 as callbacks from catch_errors(). Allow connect attempt to be
3450 interrupted painlessly with ^C (FIXME, there are still some bugs
3451 if the interrupt happens during symbol reading.). Print
3452 final message with puts_filtered, since symbol messages are
3457 * main.c (catch_errors): Only print errstring if non-null.
3458 (command_loop): Avoid an ioctl per command to test ISATTY.
3460 * remote-vx.c (net_load): make static; avoid sophomoric msg.
3461 (vx_xfer_memory): Return correct result!
3462 (vx_files_info): Indicate whether target has float or not.
3463 (vx_lookup_symbol): Complain, not error, if target gone.
3464 (vx_open): Print "Connected" msg before disabling immediate-quit.
3465 [FIXME: lookup_symbol and vx_open changes need testing.]
3467 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
3468 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
3469 contributor lines and update copyrights to 1991.
3471 Changes from an attempted H-PUX host port:
3473 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
3474 defines PT_ATTACH and PT_DETACH but not PT_KILL.
3475 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
3476 * remote-vx.c: include <sys/time.h> for HPUX.
3477 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
3478 "core_file_command" routine to BFD regime. May not work yet.
3480 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
3482 * xgdb.c: Replace X10 version with some VJ version.
3483 (FIXME: Its copyright assignment is not on record.)
3484 * xgdb.c: Update include files to X11R4 (Xaw crud).
3485 (xgdb_display_source, create_text_widget): fix call to
3486 get_filename_and_charpos. Rewack source window stuff for X11R4
3487 (gleaned from include files, and "nm's" of binary libraries, since
3488 I had no doc available).
3489 (append_selection, append_selection_word): Disable with FIXME
3490 since R4 changed interface here.
3491 (create_buttons): Add back the old set of buttons.
3492 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
3494 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
3495 Roll VERSION to 3.94 (not yet final though).
3497 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3499 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
3500 obstack_int_grow, obstack_int_grow_fast): Eliminate
3501 cast on left of assignment, which gives MIPS cc fits and is
3504 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
3505 F_ALIAS. Use printf, not fprintf, when not passing a file
3507 (compare_opcodes): Check that identical instructions have
3508 identical opcodes, complain otherwise.
3510 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
3511 was reported by Roland McGrath.
3512 (unimp): Only match if exactly zero instruction. (Roland)
3513 (branches and traps): Generate all variations of these
3514 instructions with macros, based on a single call that defines
3515 each condition name and its binary representation.
3516 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
3518 * valprint.c (val_print_fields): Take, and use, format parameter.
3519 This means that "p/x struct" again prints the elements in the
3520 desired format. Changed callers.
3522 * stack.c (frame_info): Use filtered output, and indicate wrap
3523 points. Remove kludgy formatting designed to avoid line wrap.
3525 * utils.c (wrap_here): If the line is already full (because
3526 we had printed a long indent or long wrapped string), do an
3527 immediate newline-and-indent.
3529 * m68k-pinsn.c (print_insn_arg): Bugfix from
3530 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
3531 instruction is incorrectly disassembled as bkpt #8.
3533 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
3534 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
3535 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
3536 and then will dump core (sometimes). I traced it back to an
3537 uninitialized symfile_name in psymtab_to_symtab.
3538 (const_vol_complaint): Add quotes to message.
3539 (define_symbol): Only believe line number if gcc_compiled.
3540 Avoid allocating symbol if we will not return it.
3542 Add target strata support so that newly established targets go
3543 into their right place in the target stack (e.g. a new exec file
3544 doesn't wipe out the ability to access the running process).
3546 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
3547 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
3548 and initialize it properly in all the targets.
3550 * target.h: Document strata. Change return type of push_target.
3552 * target.c (nomemory): new function for dummy memory access.
3553 (tcomplain): Rename complain, now also used in symfile.c.
3554 (push_target): Push targets within strata. New return value shows
3555 whether new target is on top of stack or not. Always keep dummy
3557 (target_files_info): Ignore dummy target.
3559 * core.c (core_open): Warn user, and skip accessing file, if the
3560 core target is not the topmost target in the stack.
3561 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
3564 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
3565 target_ops, it doesn't belong there since we have no regs there.
3566 Change name of target from machine => memory to clarify.
3568 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
3570 * Freeze version 3.93 for release.
3572 * Makefile.dist: Handle vx-share and nindy-share subdirs
3573 properly when building gdb.tar.Z.
3575 * symtab.c: lint; add no_symtab_msg to consolidate the messages
3576 printed in various places, so I could change just one copy.
3578 * dbxread.c, coffread.c: Change references to bfd->iostream
3579 to cast to FILE *, now that BFD avoids needing types defined
3580 in other header files.
3582 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3584 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
3585 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
3586 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
3587 (actually gcc -Wall).
3589 * dbxread.c: Remove first_global_sym, last_global_sym, since
3590 they are never referenced.
3592 * defs.h (baud_rate): Declare.
3593 main.c: Define it, and add the -b option to set it.
3595 * gdb-int.texinfo: Add text on how to define a new host or target
3596 architecture, prompted by Per Bothner's questions about MIPS
3599 * gdb.texinfo: Document "complaints". Change doc of -q since
3600 gdb no longer prints the copyright and blurb if you specify a file
3601 name to be debugged (just like Emacs). Add doc for Nindy-specific
3602 command line flags for specifying target serial port and such.
3603 Update copyright to 1991.
3605 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
3606 has taken over for us the job of ripping up executable files. The
3607 crud caused Per Bothner's port to not compile.
3609 * infrun.c (normal_stop): Avoid printing "Program exited
3610 normally" if we are in batch mode. This allows a GDB which
3611 executes a program on a target system, to behave like a Unix
3612 command (input from stdin, output to stdout, no extraneous
3615 * main.c (main): Allow additional machine-dependent command line
3616 options to be specified with the ADDITIONAL_OPTIONS,
3617 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
3618 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
3619 processing to occur just before the main loop with
3620 BEFORE_MAIN_LOOP_HOOK.
3621 (main): If a "core file" argument is specified, and it is not a
3622 core file, try it as a process ID to attach.
3623 (symbol_completion_function): Attempt to cope with
3624 "show screen-" TAB, not very successfully. This needs more work,
3626 (batch_file): New function, returns whether we are reading
3627 commands from an interactive tty on stdin, or from somewhere else.
3628 Called by normal_stop since it doesn't get from_tty passed down
3629 to it like many commands do.
3631 * remote-nindy.c: Handle command line options for nindy
3633 (nindy_before_main_loop): Prompt user for tty name if they
3634 don't specify it before getting to the interactive command loop.
3636 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
3637 and -r command line options. Also add hook before main loop
3638 to make it easy to specify a tty.
3640 * TODO: More things to do, one done.
3642 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
3644 * dbxread.c: Make complaint() calls pass pointer, not struct.
3645 Add complaints about badly formatted C++ type information
3646 (const/volatile indicator, and parse errors resulting in
3647 error_type). Fix C++ virtual member fn comment.
3648 (read_struct_type): Avoid bumping pointer if we got a parse
3649 error; this prevents our walking beyond the end of a string.
3650 Terminate loop on null char as well as semicolon.
3651 (process_one_symbol): Fix the LBRAC fix so that it uses the
3652 last previous SLINE, FUN, or SO record's PC address. C++ debug
3653 symbols did not have SLINE records in a useful order compared
3654 to the LBRAC records.
3655 (define_symbol): Handle "catch" records.
3657 * symtab.c (check_stub_type): Added new complain
3658 `stub_noname_complain' and added a consistency check to
3659 keep the debugger from crashing when finishing from an
3660 exception frame. A real fix will be needed later.
3662 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
3664 * infcmd.c (attach_command): Make global.
3666 * Makefile.dist (REMOTE_OBS): Make these compile by default,
3667 but make them easy to comment out. Perhaps later they should
3668 be enabled by what CPU you configure for? FIXME.
3669 (VERSION): Roll to 3.93.
3670 (pinsn.o): Remove rule for obsolete file.
3671 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
3673 Run down a problem that manifested by printing the wrong function
3674 name in stack traces of read_ofile_symtab. Turned out that the
3675 problem was the SunOS 4.1.1 (and previous) C compiler outputs
3676 the LBRAC symbol with an address in the *data* segment, which
3677 blew our binary search through the blocks.
3679 * dbxread.c: Use the complain() facility consistently to bitch
3680 about problems in the symbol file we are reading.
3681 (finish_block): Add code to check the nesting of the blocks;
3682 complain and Procrust them to fit if wrong.
3683 (make_blockvector): Check the order of the blocks, complain
3684 [but don't cope] if wrong.
3685 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
3686 symbols to be sure their PC value is greater than the last SLINE
3687 (line number) symbol we've seen, complaining and adopting the
3688 SLINE PC value if wrong.
3690 * symfile.h (struct complaint, complaint_root, complain,
3691 clear_complaints): Add.
3692 * symfile.c (complain, complaint_root, clear_complaints): Add
3693 facility to deal with non-fatal complaints and to regularize their
3695 (symbol_file_add): Clear complaint counters to allow new complaints.
3696 (initialize_symfile): Add 'set complaints' and 'show complaints'.
3698 * dbxread.c (dbx_symfile_read): Remember the address and size
3699 of the string table for the main symbol file, so we won't read it
3701 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
3702 to avoid reading the string table yet again. Lint.
3703 (throughout): Improve filtered output, including word wrap.
3704 (read_range_type): Improve Bothner's fix to handle other types too.
3706 * utils.c: Improve line wrap implementation. Handle unlimited
3707 width by making chars_per_line unsigned.
3708 (puts_filtered): New, easy, function.
3710 * defs.h (puts_filtered): add.
3712 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
3713 call the identical sort_symtab_syms() in symfile.c instead.
3715 * expread.y: Suggest the `file' command rather than `symbol-file'.
3717 * command.h (enum var_types): Add zinteger for seroable
3719 * command.c (do_setshow_command): Handle var_zinteger. Restructure
3720 nested if's into a switch.
3722 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
3723 we did not stop because of a breakpoint (it must have been for
3724 some other reason, like a "stepi"), so don't print anything.
3726 * symtab.c: Include <sys/types.h> all the time. Now that BFD
3727 doesn't include <sys/types.h>, old SunOS's require it for
3730 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
3732 A test port of gdb-3.92.6 to the Sony NEWS.
3735 Don't normally link in remote- or vx stuff.
3736 Some of it doesn't compile, and it wastes space for 99% of the users.
3737 Remove reference to no-longer-used HAVE_VPRINTF.
3738 Fixed BFD_DEP typo to BFD_DIR.
3740 Fix cast in arg to bfd_h_getlong.
3741 Make char *prefix be const.
3742 Fix how certain range types are mapped into builtin unsigned int types.
3744 Remove 2 #includes. They cause errors (on Sony, at least),
3745 and aren't needed (they wern't in earlier versions).
3747 print_address_symbolic should never demangle labels
3748 (since it prints *assembler-level* labels).
3750 [This was superseded by the change to printcmd below.]
3753 Add some "volatile" return types to avoid warnings.
3754 If MISSING_VPRINTF add vprintf function and not just macro
3755 (since vprintf is used in printcmd.c).
3757 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
3758 (The latter isn't grokked by some PCC-based compilers.)
3760 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
3762 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
3763 * nindy-share/coffstrip.c
3764 Added some forward declarations (otherwise, gcc complains
3765 about implicit extern redefined as static).
3767 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
3769 Changes inspired by Per Bothner:
3770 * printcmd.c (print_address_symbolic): Take additional parameter
3771 specifying whether to demangle.
3772 (print_address): Pass in asm_demangle to control demangling.
3773 (print_address_demangle): New fn, takes explicit arg to control
3775 * utils.c: Add new vars demangle and asm_demangle, and let them
3777 (fputs_demangled): If !demangle, just print the argument.
3778 (fprint_symbol): If !demangle, just print raw symbol.
3779 * valprint.c (val_print): Call print_address_demangle rather than
3780 print_address, to cause demangling to depend on the global
3781 rather than assembler-level demangling setting.
3782 * WHATS.NEW, gdb.texinfo: Document.
3784 * main.c (show_command): Show all settings if no arg.
3785 (initialize_main): Make "info set" the same as naked "show".
3786 * command.c (cmd_show_list): Handle prefix commands in the
3787 list, and print the name of the setting as well as its English
3788 description and value.
3790 Allow gdb functions to specify where a line should wrap if it
3791 exceeds the size of a terminal line. Use it to make the output
3793 * utils.c (set_screen_width_command): New fn, mallocs a buffer
3794 of the right size when screen width changes.
3795 (set_screensize_command, screensize_info): Remove #if 0'd fns.
3796 (wrap_here): New fn, indicates a point in the output where we
3797 should wrap the line rather than just letting it overflow at a
3799 (fputs_filtered): Implement wrapping.
3800 (n_spaces): New fn, returns a pointer to N spaces.
3801 (print_spaces_filtered): Use n_spaces.
3802 * defs.h (n_spaces): Declare.
3803 * stack.c (print_frame_info): Wrap with 4-space indent after
3804 fn name and before filename and line number.
3805 * printcmd.c (print_frame_args): Wrap with 4-space indent
3806 before each argument name is printed.
3807 * valprint.c (value_print): Wrap with no indentation before
3809 (val_print_fields): Wrap with indentation relative to nesting
3810 level before each field name.
3811 (val_print): Wrap with nesting indentation before array elements.
3812 * command.c (do_setshow_command): Avoid extra newlines,
3813 wrap with 4-space indent around values printed, end with period.
3814 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
3816 * breakpoint.c (breakpoint_1): Implement addressprint for
3817 "info breakpoints" display. Change file name and line number
3818 format to " at file:nnn" rather than " (file line nnn)".
3819 * gdb.texinfo: Document.
3822 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3824 Frozen for gdb-3.92.6 release.
3826 README, WHATS.NEW: Update for 3.92.6 release.
3828 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
3829 coffread.o from configs since it is now built by default.
3830 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
3831 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
3832 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
3833 from configs since it is now built by default.
3835 Makefile.dist: Update for release 3.92.6. Handle files that
3836 have been moved to ../include, ../getopt, or ../bfd. Add
3837 saber.suppress and tests directory. Add config.status to
3838 the release (it will say "none").
3840 coredep.c: Minor formatting fixes.
3842 These changes were made in early December but only checked in now:
3843 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
3844 nindy-share/nindy.c: lint
3845 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
3846 register values coming back from the target; we store values
3847 in target byte order everywhere.
3849 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
3851 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
3853 * valprint.c (cplus_val_print, val_print_fields): New functions,
3854 which print C++ objects. They conspire to avoid printing a
3855 virtual base class more than once, following all the twists and
3856 turns of C++ virtual base rules.
3857 (val_print): Call the above rather than do it by hand.
3859 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
3860 symbol file, not for added files like shared libs. This really
3861 needs to be generalized to a timestamp per file.
3863 * core.c (cleanup_core): Avoid coredump if no core file.
3865 * config.gdb: Accept -host or -target in place of +host or
3868 * coffread.c (find_linenos): Avoid desupported BFD interface
3869 to line numbers. We still read them manually rather than using
3870 BFD's "generic" features.
3872 * gdbrc.tex, threecol.tex: Add GDB reference card and its
3874 Makefile.dist: Add refcard to OTHERS list for creating tar files.
3876 * Makefile.dist: Eliminate use of $< in explicit targets.
3878 * readline/Makefile: Use $< rather than $*.c, which does not
3879 include the VPATH in GNU Make.
3881 * tconfig/i960-bout, tconfig/i960-coff: These are identical
3882 copies of tconfig/i960, added for global configuration
3883 compatability. All i960 versions can read both coff and b.out.
3885 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
3886 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
3889 * TODO: Think of more things to do.
3891 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
3893 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
3894 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
3895 64-bit float conversion.
3897 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
3898 equivalent to sun?os4 so global config works.
3900 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
3902 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
3904 * main.c: Only declare linesize once; declare pagesize not at
3905 all, since it is never used.
3906 (main): Clear newly allocated line before it is used.
3908 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
3910 Further stabilization for the Intel 960.
3912 * Makefile.dist: Parameterize the location of the "include"
3913 and "bfd" directories, as well as "getopt". Add symfile.c.
3914 Link in both dbxread and coffread. Fix up "make depend" to
3915 rewack the locations of include, bfd, and getopt in its output.
3917 * README: Document moving include files, improve some of
3920 * coffread.c: Move common code out to symfile.c. Change
3921 symbol_file_command style interface to use new *_symfile_init
3922 and *_symfile_read interface under BFD. Use BFD internal
3923 info to locate line table, symbols, etc.
3925 * core.c (core_fetch_registers): Rename to get_core_registers
3926 to avoid confusion with fetch_core_registers.
3927 (register_addr): Move to coredep.c, which is already machine
3928 dependent. This leaves core.c pretty clean of dependencies.
3930 * coredep.c (register_addr): Accept this routine from core.c.
3932 * dbxread.c: Move common code (with coffread.c, etc) into new
3933 symfile.c. Each psymtab now contains a pointer to the
3934 format-dependent function that knows how to read it in. Make
3936 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
3937 (process_one_symbol): Add code to complain about a "compiler bug
3938 we muzzle here", if we actually see it.
3940 * eval.c (evaluate_subexp): Insert missing "break" statements
3941 in code that determines whether a variable is an lvalue in
3942 memory, register, or whatever. I detected this via a compiler
3943 bug in which it *almost* mashed out the whole switch statement.
3945 * gdb-int.texinfo: Add minor sections on configuring gdb for
3946 release, and about the README file.
3948 * infcmd.c (registers_info): Fix formatting somewhat. Still
3949 not as pretty as before, but it handles byte swapping.
3951 * remote-nindy.c: If data cache routines are interrupted while
3952 waiting for the remote end, be sure that any uninitialized cache
3953 blocks are on the free list, not on the valid list!
3955 * symfile.h: Flesh out this header file with all the various
3956 routines and variables that have been merged in from dbxread.c
3957 coffread.c, and symtab.c to symfile.c.
3959 * symfile.c: New file, containing code common to dbxread.c,
3960 coffread.c, and some code from symtab.c. All generic code for
3961 reading symbol files should be in here now.
3962 (unrecord_misc_function): Remove unused function.
3964 * symtab.h: Remove file-reading things to symfile.h.
3966 * symtab.c: Remove file-reading things to symfile.c.
3968 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
3969 to decode i960 fault types.
3971 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
3972 target.c: Change type of the "resume" function from int to void,
3973 since its result was never used.
3975 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
3977 * main.c: Replace "stupid" with "caution"; you now "set caution
3980 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
3982 * infcmd.c (do_registers_info): Call val_print to deal with the
3983 byte order of the registers being printed. FIXME, this makes
3984 the formatting of the output uglier.
3986 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
3987 defined, call it for signals the debugger doesn't itself use.
3988 The i960 uses this for more detailed fault information.
3990 * remote.c (remote_open): If arg is null, print help rather than
3993 * sparc-xdep.c (register_valid): Avoid declaring size, since
3994 various modules will think of various sizes depending on the
3995 architecture of their tm-file. FIXME, we need protection against
3996 actually entering one of those modules, which would clobber
3997 storage if not for the target architecture compiled into gdb.
3999 * stack.c (up_command, down_command): Always print the frame
4001 (up_silently_command, down_silently_command): New commands
4004 * i960-pinsn.c (reg), i960-tdep.c: Lint.
4006 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
4007 more parameters than it used to.
4009 * findvar.c (registers): Increase slop to 256 bytes, which should
4010 protect us against even most RISC machines with large register
4012 (locate_var_value): Move declaration inside related ifdef.
4014 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
4015 throughout, to avoid throwing away buffered input from the board.
4016 (nindy_wait): Supply_register takes addr_of_value, not value.
4017 (i960_print_fault): Renamed from i80960_fault.
4018 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
4019 (nindy_store_registers): Avoid regs_changed stuff, just stuff
4021 (nindy_create_inferior): Don't bother to write PC_REGNUM since
4022 we can set the PC in the call to proceed(). Unpush nindy_ops
4023 before pushing it on top, to avoid message to user. Eliminate
4024 commentary from Unix machines that just misleads here.
4025 (reset_command): Fix error message to suggest target command.
4027 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
4029 Release 3.92.5 as frozen.
4031 Stabilize the merged release...with help from lint, Saber C,
4034 Everywhere: Add include files needed to declare return types
4035 of functions called.
4037 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
4039 * breakpoint.h: Add undeclared breakpoint functions, and some
4040 functions for display handling since I couldn't think of a better
4043 * breakpoint.c (insert_breakpoints): Make code for disabling
4044 shared library bkpts more likely to work. It's used when we
4045 rerun a program and stop before the shared library has been
4047 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
4048 cast from pointer, so it squeezes through catch_errors.
4049 (bpstat_stop_status): Fix logic broken some time ago. We now
4050 always create a bpstat if the stop address matches a breakpoint,
4051 even if we don't stop there -- just like the old code used to do
4052 before I got my fingers into it (sigh).
4053 (breakpoint_1): Print "ignore count" after "stop only if"
4054 condition, since that's how it actually works.
4055 (mention): Handle watchpoints as well as breakpoints.
4056 (watch_command): use set_raw_breakpoint and mention to do most
4057 of the work (and initialize all the fields!). Only pass one
4058 arg to parse_c_expression, since that's all it takes.
4060 * command.c (not_just_help_class_command): Rename arg to args
4061 since we ignore "unused argument" warnings on vars named "args".
4062 inflow.c (child_terminal_info): ditto.
4063 infptrace.c (kill_inferior): ditto
4064 main.c (catch_errors, version_info, quit_command, pwd_command,
4065 source_command, dump_me_command, editing_info,
4066 set_history_size_command, set_history, show_history,
4068 stack.c (locals_info): ditto
4069 target.c (target_files_info): ditto
4070 valprint.c (set_input_radix, set_output_radix): ditto
4072 * core.c: Remove old variables for handling core and exec file
4073 sections (data_start, data_end, stack_start, stack_end,
4074 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
4075 text_end, exec_data_start, exec_data_end, text_offset,
4076 exec_data_offset, data_offset, stack_offset). They're
4077 superseded the more general build_section_table and
4079 (get_exec_file): Mention the `file' command.
4080 (read_memory_check): Rename to memory_error, and only call it
4081 in the case of an actual error.
4082 (read_memory, write_memory): call memory_error.
4083 (core_fetch_registers): Register section name is ".reg".
4085 coredep.c: Remove a bunch of crud now that all this file does
4086 is pull the registers out of a core file.
4087 (fetch_core_registers): Rewrite to actually work, I hope.
4089 dbxread.c: Use a.out.gnu.h, not system a.out, now.
4090 Replace index() with strchr(). Remove all the pre-BFD macro
4091 definitions for accessing the symbol file.
4092 (struct dbx_symfile_info): Encapsulate the information that
4093 dbx_symfile_init needs to pass to dbx_symfile_read in this
4096 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
4097 dbx_symfile_discard): Rearrange symbol file reading to divide
4098 the format-specific part from the format-independent part,
4099 leaving the format-independent part such as file name expansion
4100 and opening in symtab.c. This replaces
4101 partial_symbol_file_open and partial_symbol_file_read.
4102 Symbol_file_read, add_file, add_file_target_command,
4103 add_file_addr_command move to symtab.c. Pass an explicit
4104 "mainline" flag for when reading the main symbol table, rather
4105 than relying on the offset address to be zero or nonzero.
4107 (dbx_symfile_read): Don't allow void *'s to be printed as
4109 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
4110 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
4111 macro" debug version really work.
4112 (read_dbx_symtab): Remove unref'd parameter inclink.
4113 Avoid swapping N_SLINE symbols, for speed.
4114 Merge N_TEXT!N_EXT case with the other external symbol
4115 definitions' case. Add comments.
4116 (start_psymtab): Allocate the symfile name in the psymtab on
4117 the psymbol_obstack, rather than using the caller's storage.
4118 (end_psymtab): Only allocate a dependencies list if there are
4120 (psymtab_to_symtab_2): Use BFD when reopening file to read
4121 its symbols for real.
4122 (read_struct_type): Add FIXME comments where it needs work
4124 (read_huge_number): Add FIXME about overflows.
4125 (read_range_type): Add FIXME about comparing a long to 1<<32.
4127 * coffread.c: Minor changes to move things closer to the new
4128 regime with symtab.c and dbxread.c Major work is still needed
4131 * exec.c (exec_file_command): Remove old variables (see core.c
4133 (xfer_memory): If memory transfer is right at the end of a
4134 section, don't lose.
4136 * findvar.c (get_saved_register): If value is in a real
4137 register, LVAL is lval_register, not lval_memory.
4139 frame.h: Declare print_sel_frame and record_selected_frame.
4141 gdb-int.texinfo: New file, for GDB internals documentation.
4142 Very simple, unformatted doc of cleanups is there for now.
4144 gdbcore.h: Remove obsolete variables that described a.out
4145 section addresses and offsets. (See core.c above.)
4146 Declare fetch_core_registers and registers_fetched.
4148 getopt.c: Declare char *alloca(); even on SPARC.
4150 infcmd.c (run_command): Call target_kill rather than
4152 (step_command, next_command, stepi_command, nexti_command):
4153 Declare from_tty parameter even though we don't use it.
4154 (run_stack_dummy): argument BUFFER is a char array, not
4155 a pointer to REGISTER_TYPE.
4156 (finish_command): using_struct_return needed a value *,
4157 not a struct symbol *.
4159 * infptrace.c (child_xfer_memory): To avoid dependency on
4160 where sections are in memory, try PT_WRITE_D and if that fails,
4161 try PT_WRITE_I. Most Unixes don't care which you use.
4163 * infrun.c (step_resume_break_shadow): Change to array to
4164 match other breakpoint shadow storage.
4165 (clear_proceed_status): Pass address of bpstat to
4166 bpstat_clear, not the bpstat itself.
4167 (child_create_inferior): FIXME comment about if the child
4169 (start_inferior): Remove old function.
4170 (child_open): Use target_kill rather than kill_inferior.
4171 (wait_for_inferior): Ditto.
4172 (insert_step_breakpoint, remote_step_breakpoint): Use
4173 new step_resume_break_shadow.
4175 * inftarg.c (child_wait): If all child processes die,
4176 pretend that the one being waited for exited with signal 42.
4178 * main.c (command_line_input): When scanning for comments,
4179 don't coredump on unclosed quotes.
4180 (quit_command): Use target_kill rther than kill_inferior.
4181 (_initialize_main): Rename class_user from "user" to
4184 * printcmd.c (print_command_1): Initialize "fmt" if no format
4185 is specified by the user.
4186 (print_frame_args): Only add to args_printed if we are
4187 actually fetching args from the stack (avoiding undefined
4189 (_initialize_printcmd): Remove bogus \{ from string.
4191 * remote-eb.c (eb_open): Avoid coredump on no argument.
4193 * remote-nindy.c: Bring out of Intel environment into new
4194 target environment. Remove all conditional compilation on
4195 I80960. Massive hacking throughout.
4196 (nindy_xfer_inferior_memory): New routine stolen from
4198 (nindy_create_inferior): New routine pieced together, probably
4199 not quite working yet.
4200 (nindy_ops): New target_ops struct for nindy.
4202 * remote-vx.c: Use write_memory rather than target_write_memory
4203 to get error checking.
4204 (vx_add_file_command, vx_open): Use symbol_file_add rather than
4206 (vx_create_inferior): Use target_terminal_ours...
4208 * signame.c (_initialize_signame): Always initialize, since
4209 we need the table for things other than psignal.
4211 * solib.c (solib_add): Use symbol_file_add, not add_file.
4212 (solib_address): Return boolean result rather than struct
4213 pointer which nobody else knows the type of.
4215 * sparc-tdep.c, valops.c: Use write_memory rather than
4216 target_write_memory, to get error checking.
4218 * stack.c (locals_info, catch_info, args_info,
4219 get_selected_block, frame_command, up_command): Use
4220 target_has_stack, rather than have_inferior_p or
4223 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
4225 * symfile.h: New file, defining the interface between the
4226 generic and object-file-specific symbol reading code.
4228 * symtab.c: Move generic symbol-reading interface to symtab.c,
4229 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
4230 table to map BFD targets to symbol-reading modules in GDB.
4231 Change index to strchr.
4232 (lookup_struct_elt_type): Use error() rather than hand-made
4233 simulations thereof.
4234 (lookup_partial_symbol): Speedup slightly when length == 0.
4235 (symbol_file_add): New function.
4236 (symbol_file_command): Call it.
4237 (symfile_open, symfile_init): New function.
4238 (add_file_target_command, add_file_addr_command): moved from
4241 * target.c (target_command): use target_kill.
4243 * target.h (target_files_info): Don't declare, never called
4246 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
4247 files to determine stack end address.
4249 * valarith.c (value_x_binop, value_x_unop): Change error message
4250 to be more useful. Pass proper argument to value_struct_elt.
4252 * valops.c (value_assign): FIXME comment that long long
4253 bitfields will break here.
4255 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
4256 Update `make saber_gdb' to work better.
4258 * TODO: A woman's work is never done.
4260 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
4261 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
4262 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
4263 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
4264 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
4265 valops.c, valprint.c, exec.c: Lint.
4268 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
4270 Continuing Intel 960 port merge of GDB.
4272 * Makefile.dist: Merge i960 "nindy-share" files. Rename
4273 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
4274 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
4275 Wack over "make depend" so it handles files in subdirectories
4276 vx-share, nindy-share, bfd, and in the current directory.
4278 * blockframe.c (get_prev_frame_info): Remove fatal error
4279 if stack not defined.
4281 * core.c (core_open, core_detach): New functions that handle
4282 the old "core-file" command as "target core" and "detach" instead.
4283 (core_file_command): Call them.
4284 (core_xfer_memory): Use common routine xfer_memory.
4286 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
4287 dbxread now uses bfd for everything but symbol reading itself.
4288 BFD internals are used to drag out the relevant file offsets.
4289 (partial_symbol_file_open): Change args all around for BFD.
4291 * symtab.c: Rename "value" to "val" everywhere, so we can
4293 (symbol_file_command): New command, moved from dbxread.c
4294 and coffread.c. It uses BFD to read the file, then vectors
4295 based on its type, to dbx or coff symbol readers.
4296 * symtab.h: Extern a few vars for symbol_file_command.
4298 * target.h: Breakpoint takes a char * save area, not a char **.
4300 * valprint.c (val_print): When unpacking bitfields, offset
4301 the address in gdb of the value, if it is declared with a shorter
4302 type. Remove the last "runtime kludge test" of host byte order.
4304 * utils.c: Remove old my_bfd_read routine.
4306 * stack.c (frame_info): Use target_has_stack. Print program counter
4307 register's actual name rather than "pc", since it's called the
4308 "ip" (instruction pointer) on the i960 (sigh).
4310 * target.c (target_command): Add command for selecting a target
4311 type and calling its open routine. This is used for initiating
4312 communication with a particular target, in a generic way.
4314 * tm-i960.h: Update for modern gdb. Remove semicolons from
4315 various macros. Handle reading struct return convention, and
4316 error-out attempts to return structs with the "return" command.
4317 Be sure gdb doesn't think we know how to call functions in the
4320 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
4321 to i960_xxx in lower case.
4322 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
4323 not being defined yet.
4325 * remote.c (remote_open): Call start_remote to initialize
4326 wait_for_inferior during open.
4327 (remote_xfer_inferior_memory): Return length written rather
4330 * remote-vx.c (target_command -> vx_open): Use new generic
4332 * remote-eb.c, inftarg.c, exec.c: ditto.
4334 * infrun.c: Fix comments.
4335 (attach_program -> child_open): Use new generic target command.
4336 (wait_for_inferior): Clear saved register values before target_wait,
4337 so target_wait can set some of them if convenient.
4339 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
4340 Return success indicator, not void.
4341 (child_xfer_memory): Avoid fetching initial word if we'll
4342 overwrite it anyway.
4344 * infcmd.c (attach_command): Use new generic target open routine.
4345 (_initialize_infcmd): Update doc on attach and detach commands.
4346 (do_registers_info): Merge in a byte-order problem as a FIXME
4349 * findvar.c (find_saved_register): Avoid problem in current frame.
4350 (read_relative_register): Ditto.
4351 (write_register): Convert byte order on the way out.
4353 * exec.c (file_command): Add.
4354 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
4355 (xfer_memory): Common function between core_xfer_memory and
4357 (exec_xfer_memory): Use it.
4359 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
4361 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
4362 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
4363 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
4365 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
4367 Merge Intel 960 port of gdb, continuing...
4369 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
4370 symbol_file_command): Pass from_tty arg to hush 'em up.
4372 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
4373 Add magic numbers for 960 COFF format.
4375 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
4377 Merge Intel 960 port of gdb, from Intel "1.2" release.
4379 CHANGE_LOG entries from their port, which was based on
4382 Thu Sep 6 11:02:22 PDT 1990
4383 Remove temp file if download is interrupted.
4385 Wed Aug 1 09:08:33 PDT 1990
4386 Now uses binary protocol to talk to NINDY.
4387 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
4388 Times out after 5 seconds when trying to talk to NINDY.
4390 Tue May 29 12:54:49 PDT 1990
4391 Added variable baud rate (-b switch).
4392 Source code reorganization.
4394 Thu Apr 26 11:09:55 PDT 1990
4395 More cleanup of batch mode; specifically, execute "-s", "-e", and
4396 "-se" switches as soon as they are encountered on the invocation line.
4398 Fri Apr 20 13:47:15 PDT 1990
4401 Thu Apr 19 09:54:28 PDT 1990
4402 Add 'reset' command.
4404 Wed Apr 18 09:48:07 PDT 1990
4405 After opening remote tty, wait for 1 second to go by without input
4406 from it before trying to talk to NINDY (fixes problems with the
4407 Heurikon HK80/V960E).
4409 Mon Apr 4 16:33:05 PDT 1990
4410 Some output was not being suppressed in 'batch' mode.
4412 Thu Mar 22 15:31:11 PST 1990
4413 Ask user if old symbol table should be deleted when new file is
4416 Allow user to run a program downloaded before gdb960 was brought up.
4418 Correct "exec-file" help message for i80960 context.
4420 Correct bug in calculating user space address: could occasionally
4421 corrupt user program.
4423 Make sure to zero low-order bits in rip's because of bug in 960CA
4424 A-step part: could cause operation faults when "next"ing across
4427 Correct bug that made it impossible to get source line numbers for
4428 code loaded at addresses higher than 0x7fffffff.
4430 Wed Jan 10 12:43:22 PST 1990
4431 Open remote tty for exclusive use.
4433 Fri Jan 5 12:14:42 PST 1990
4434 Correct disassembly (CA manual was right after all):
4435 opcode for sysctl is 0x659
4437 Mon Oct 23 12:03:04 PDT 1989
4438 Use G960BASE and G960BIN environment variables to find 'sx' utility.
4440 Mon Oct 16 14:15:09 PDT 1989
4441 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
4443 Mon Oct 2 15:56:31 PDT 1989
4445 Added 960CA disassembly support.
4447 To simplify maintenance:
4448 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
4450 - eliminated opcode.h: incorporates tables into i960-pinsn.c
4451 - moved 960-specific routines from i960-pinsn.c to i960-md.c
4452 - made disassembly interface identical to that in gdmp960.
4456 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
4458 * target.h: Allow targets to stack. Add target_has_memory,
4459 _registers, etc. Restructure memory access and "info files"
4460 to walk the target stack.
4461 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
4462 target.c: Change tables to match target.h.
4463 * inflow.c (child_mourn_inferior): pop child_ops.
4464 (generic_mourn_inferior): Use new has_stack flag.
4465 * infptrace.c (child_xfer_memory): New memory regime.
4466 * inftarg.c (child_files_info): New "info files" regime.
4467 * remote-eb.c: New memory regime, new info files.
4468 * remote-vx.c: New memory regime, new info files. Now use
4469 separate targets for VxWorks attachment to machine, and
4470 actually running a process under VxWorks, since one has
4471 stack & execution & regs and the other doesn't.
4472 * remote.c: New memory regime, new info files.
4473 * sparc-xdep.c (fetch_core-registers): New memory regime.
4474 * target.c: New routines and support for stacked targets,
4475 new memory regime, new info files regime.
4478 Generalize section handling for an arbitrary number of sections,
4479 including use of the new BFD (binary file) library.
4480 * gdbcore.h: Add struct section_table.
4481 * exec.c (build_section_table): Iterate all sections and
4482 record what gdb needs to know about them.
4483 (exec_command): Use it.
4484 (exec_xfer_memory): Use the table.
4485 (exec_files_info): Print the table.
4486 * core.c (core_file_command, core_xfer_memory, core_files_info):
4488 * source.c (find_source_lines): Use bfd_get_mtime.
4489 * dbxread.c: Quick changes to make it compile with new BFD.
4490 * utils.c (error): Avoid using bfd_error in generic routines.
4492 * core.c (core_fetch_registers): Get from the ".regs" section of
4494 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
4496 * inferior.h (attach_flag): Export.
4497 * infcmd.c (run_command): use new target_create_inferior.
4498 * infrun.c (child_create_inferior): Don't return result.
4499 * Makefile.dist (VERSION): 3.91.4.
4501 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
4503 * breakpoint.c (bpstat_num): Handle breakpoints which have
4504 since been deleted, such as temporary breakpoints.
4505 infcmd.c (program_info): ditto.
4507 * core.c (core_file_command): Display the frame where the core
4512 * remote-vx.c (target_command): Merge in target command from
4513 targ-vx.c. A few other cleanups.
4515 * TODO, Projects: Lots more stuff to do...
4517 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
4519 Massive changes to wall off the remote-debugging interface
4520 behind a function vector. The port to handle VxWorks targets
4521 is also part of this.
4523 All files: Replace references to renamed functions,
4524 remove references to remote_debugging, remove references to
4525 have_include_file, have_core_file in favor of target_has_stack,
4526 target_has_memory, etc.
4528 * Modularize the breakpoint interface.
4529 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
4530 a breakpoint instruction.
4531 breakpoint.c: struct breakpoint's shadow_contents now sized as
4533 (insert_breakpoints): Vector to target to install breakpoints.
4534 (remove_breakpoints): Vector to target here too.
4535 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
4536 sparc-tdep.c (single_step): Use new breakpoint interface for
4537 the single-step breakpoints.
4538 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
4539 New file, contains routines to insert and remove breakpoints by
4540 reading out the old contents and later replacing them. This is
4541 how ptrace breakpoints work, and many remote systems as well.
4543 * tm-vxworks68.h: New config file, overrides a few things for
4544 Wind River's preferences.
4546 * target.h: New file, for transfer vector used to talk to the
4547 inferior (child, attached, core, exec, remote, etc). All accesses
4548 to the thing being debugged should come through these vectors.
4549 target.c: New file, routines to handle transfer vector.
4550 (various files): Add transfer vectors XXX_ops for the various
4551 targets and pseudo-targets (core files, etc) we support.
4553 * breakpoint.c (bpstat_stop_status): Further explorations of
4554 watchpoints and why things don't work all the time.
4555 (bpstat_alloc): New fn to allocate a bpstat and chain it.
4557 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
4558 the local gdbinit if it doesn't already have it.
4560 * core.c (core_ops): add and install.
4561 Allow core debugging without exec file.
4563 * dbxread.c (free_and_init_header_files): Merge two fns.
4564 (end_symtab): Free named symbol table when a new version comes in.
4565 (read_dbx_symtab): Relocate all kinds of symbols with base
4566 address. First step toward handling different text, data, bss
4568 (add_file_addr_command): Renamed add_file_command.
4569 (add_file_command): Vector to remote handler.
4570 Add "load" as an alias for "add-file" command.
4572 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
4573 non-returning functions.
4575 * exec.c: Add exec_ops, and push it as a target when an exec
4578 * infcmd.c (run_command): Pass executable file name and arg list
4579 separately when starting an inferior. Permit "run" when no exec
4580 file is specified, for VxWorks.
4581 (detach_command): Move to child_detach in inftarg.c.
4583 * inftarg.c: New file. Unix-child-specific routines, and the
4584 child_ops structure.
4586 * inferior.h (registers): Export "registers" as the way for
4587 target dependent register handlers to find gdb's local copy of
4588 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
4589 since it is now used by places that want wait_for_inferior to
4590 handle the grunge but want to see every trap from the inferior.
4592 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
4593 Eliminate remote_debugging hooks in terminal handling.
4595 * infrun.c: Replace start_inferior with child_create_inferior.
4596 Move all the hair of Unix shells and ptrace idiosyncracies into
4597 child_create_inferior, so remote handlers don't have to deal.
4598 Remove running_in_shell. Rename stop_after_attach to
4599 stop_soon_quietly, and use it in a few other places where we want
4600 to just call wait_for_inferior and get control back on the first
4601 trap. trap_expected now never takes a value > 1.
4602 (init_wait_for_inferior): Initialize static vars when a new
4605 main.c (gdbinit): Add new hook for .gdbinit file name, let
4606 it be overridden by config files as GDBINIT_FILENAME.
4607 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
4608 Both of these are used for VxWorks gdb.
4610 mcheck.c: rename include file "gmalloc.c" to avoid problems
4611 with system include file "malloc.c".
4613 param-no-tm.h: New include file, same as param.h but does not
4614 include the default "tm.h" file. This is used in files where
4615 the target is known, e.g. remote-eb.c or sparc-xdep.c.
4617 param.h: Now just a shell that includes tm.h and param-no-tm.h.
4619 remote-vx.c: New file, VxWorks remote debugging support. Uses
4620 RPC routines that are shared with the target system, in directory
4623 remote.c: Vectorize remote interface.
4625 source.c: Globalize source_path, and make an alias "l" for "list"
4626 since we now have the "load" command.
4628 sparc-xdep.c: Use new param-no-tm.h.
4630 symmisc.c (free_named_symtab): Add new function from Wind River.
4631 However, ifdef it out for now while we think about what it should
4634 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
4636 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
4637 non-Unix-children handle this with their own code in the target
4640 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
4641 source and target lists. Add vx-share to default list of include
4642 directories. Add new files to src and target lists: mem-break,
4643 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
4644 ${srcdir} versions of munch and createtags are used.
4646 * valops.c (find_function_addr): Split out of call_function.
4647 (call_function_by_hand): Rename call_function; this function
4648 calls functions in the target by laboriously patching the target
4649 word-by-word with the right stack, args, regs, etc.
4652 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
4654 Handle AMD 29000 a bit better.
4656 * remote-eb.c (readchar): Mask received char log to make it readable.
4657 (remote_start): Pass arguments down to executing program.
4658 Make startaddr unsigned.
4659 infrun.c (start_inferior): Accept args, pass them to
4661 infcmd.c (run_command): Pass args down to start_inferior.
4663 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
4664 the target object file format.
4665 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
4667 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
4668 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
4670 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
4672 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
4673 * TODO: We did a few things, we have more to do though.
4675 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
4676 * inflow.c (inferior_died): Clear deferred stores.
4678 * Debug problems with dummy frames and calls to the inferior.
4679 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
4680 * sparc-tdep.c (do_restore_insn): Simplify.
4681 (sparc_frame_find_saved_regs): Simplify and fix what we find.
4682 (sparc_push_dummy_frame): Simplify and fix what we push.
4683 (sparc_pop_frame): Slightly more hair here, deciding whether
4684 we are restoring a saved PC or returning to a return address in %i7.
4685 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
4687 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
4688 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
4689 * obstack.h (chunkfun): ditto.
4690 * defs.h (xmalloc, xrealloc): ditto
4692 * utils.c (quit): Grab the terminal from the child if necessary.
4694 * inflow.c (term_status_command): Rename to term_info, change
4697 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
4698 (is_delayed_branch): Speed up.
4699 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
4700 Still missing some float ops, and needs testing.
4702 * Support for input and output radixes other than base 10
4703 * defs.h (input_radix, output_radix): Declare.
4704 * expread.y (yyparse, parse_number): Handle changes of input
4705 radix, and ambiguous names-or-numbers in radixes >10.
4706 * printcmd.c (print_scalar_formatted): Print formatted hex
4707 numbers in varying column widths.
4708 * valprint.c (val_print): Use output_format to print scalar ints.
4709 (set_input_radix, set_output_radix, set_radix): Create.
4710 (set_output_radix): Set output_format from output_radix.
4711 (_initialize_valprint): add `set radix' but leave the others off.
4713 * main.c (execute_command): Let stupid questions be turned off.
4714 (_initialize_main): Handle "set stupidity", etc.
4716 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
4717 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
4719 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
4721 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
4722 bfd stuff is still screwed up, but with some manual work, it
4725 * breakpoint.c (bpstat_do_actions): Start over if a command
4726 proceeds the inferior, since the inferior will have stopped and
4727 will need to have its new stop-actions taken care of.
4729 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
4730 compiler fits, simplify it.
4732 * gdb.texinfo (directory command): Doc new dir command.
4733 source.c (directory_command): "dir" now puts things on the front
4734 of the path, moves dups up front, and handles multiple names
4735 on the command line, inserting each one in order. It also
4736 blows away cached line and full_filename info.
4738 * stack.c (backtrace_command): Skip "more stack frames follow"
4741 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
4742 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
4743 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
4744 The only odd one was Gould NP1, which had defined vprintf to
4747 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
4748 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
4749 variable, inspect_it.
4750 valprint.c (print_string, val_print): Use the global inspect_it
4751 to indicate whether to print in Epoch style or normal style.
4753 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
4755 * printcmd.c (call_command): add an alias for the "print" command
4756 which runs expressions and doesn't print the result if void.
4757 (print_command_1): implement it.
4759 * command.c: Remove #if 0'd code. Initialize all the fields
4760 in add_cmd (). Rename do_nothing_command to
4761 not_just_help_class_command, and make it externally visible.
4762 command.h: add user_commands to struct.
4763 * main.c (define_command): Don't overload c->function with a char
4764 string as well as a function pointer.
4766 * eval.c (evaluate_subexp): Reinstall tiemann changes to
4767 calling convention of value_struct_elt () that got dropped in
4770 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
4771 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
4773 * tm-sparc.h (POP_FRAME): replace some constants with defines.
4775 * sparc-xdep.c (store_inferior_registers): defer stores to regs
4776 until a good time (e.g. when we are about to run the child),
4777 saving ptrace calls.
4778 * infrun.c (proceed): handle DO_DEFERRED_STORES.
4779 * tm-sparc.h: define DO_DEFERRED_STORES.
4781 * sparc-xdep.c (store_inferior_registers): when storing float
4782 registers, don't store stack regs too. When storing the SP,
4783 however, DO store the stack regs too. This fixes a bug in which
4784 the dummy frame is not recognized when a call_function finishes,
4785 because its frame pointer (in the stack regs) was never
4787 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
4788 even though we don't know how to read them from an inferior.
4789 valops.c (call_function): Comment about storing SP.
4791 * infrun.c (save_inferior_status): Save away the original bpstat
4792 chain so it can be restored later. Install the copied version for
4793 use by whoever saved the status. It will be blow away by
4794 restore_inferior_status, and the original chain restored. This is
4795 important for people who have pointers into the original.
4797 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
4798 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
4799 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
4802 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
4804 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
4805 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
4806 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
4808 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
4810 * Merge Mike Tiemann's multiple inheritance changes from Sun.
4811 Store the baseclasses in a type struct starting from array element
4812 0 rather than from the unusual array element 1.
4814 dbxread.c: the above.
4815 (virtual_context): Add
4816 Read new debug information about which virtual function table
4817 a virtual function is from, and store it in fn_field.fcontext.
4819 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
4820 TYPE_FN_FIELD_STATIC_P.
4822 symtab.c: the above.
4823 valops.c: the above. Handle pointer casts of object *'s.
4824 (search_struct_method): Add.
4825 (value_struct_elt): First arg is now a pointer to a value, and is
4828 valprint.c: the above.
4829 values.c (value_virtual_fn_field): Add type arg. Handle
4830 offsetting to the proper object when calling virtual fns.
4832 (baseclass_addr): Add valuep arg.
4834 * README: Document the current state of BFD config (missing).
4835 * TODO, ChangeLog, Makefile.dist: Roll version.
4836 * WHATS.NEW: Add summary of changes since 3.5.
4838 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
4840 * dbxread.c (read_struct_type): Clear bit vectors whenever
4842 symtab.c (B_CLRALL): define.
4844 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
4845 using == rather than =. Huh... This fixes the dreaded problem
4846 wherein builtin_type_int becomes TYPE_CODE_FLT.
4848 * core.c (info_files): Show the inferior pid.
4850 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
4851 already knows how to look in the source directory.
4853 * Remove psymtab hair from many places. Remove duplicated code
4854 for searching symbol tables. Hide psymtabs from most places.
4855 Make it fast to get from a psymtab to its symtab.
4857 blockframe.c (blockvector_for_pc): Remove psymtab hair.
4858 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4859 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4860 dbxread.c: export psymtab_to_symtab, make it work if called N times.
4861 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
4862 new symtab completely. New psymtabs get symtab pointer
4863 initialized to zero. Remove MI warning printf.
4864 symtab.h: Comments. Add psymtab to symtab pointer.
4865 (PSYMTAB_TO_SYMTAB): New macro.
4866 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
4867 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
4869 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
4871 (print_frame_info): Avoid special-casing symbols that have not yet
4874 * source.c (open_source_file): Quick path if we have already
4875 located the source file by its full name.
4877 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
4878 find_pc_psymtab. When a name is found in the misc function
4879 vector, search the symbol table for its mangled name, not the
4880 name that the user typed.
4882 * bfd.h: Fix missing comment terminators, make #endifs match.
4884 * valarith.c (value_less): Handle unsigned int comparisons.
4885 Add FIXME about pointer compares, which assume host and target
4886 pointers are the same.
4888 * command.c (do_nothing_command): lint
4889 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
4890 fix comments on debug symbol format for visibility. Actually set
4891 visibility of symbols.
4892 main.c (echo_command): lint; use <readline/history.h>.
4893 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
4894 obstack.h (_obstack_blank): Rearrange pointer math to avoid
4895 pointing past end of allocated memory; saber complains.
4896 obstack.h: Declare the external functions that we use.
4897 valarith.h: use <string.h>
4898 solib.c (solib_add): lint.
4900 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
4902 * main.c (initialize_main): Default info_verbose to off, now that
4903 symbol reading is fast.
4904 (quit_command): Avoid clobbering exec_bfd while quitting.
4906 * Initial BFD (binary file diddling library) merger:
4907 coffread.c: Change AOUTHDR to struct exe_hdr.
4909 core.c: initialize initialized data at compile time.
4910 (core_file_command): Move from coredep.c, convert to bfd.
4911 (xfer_core_file): Convert to bfd.
4912 exec.c (exec_file_command): use bfd routines.
4914 mips-tdep.c: Remove exec_file_command and friends.
4917 * coredep.c: (fetch_core_registers) Convert core_file_command to
4918 fetch_core_registers.
4919 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
4921 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
4922 (my_bfd_read): More bogosity, which I don't think we call.
4923 (program_name): Remove this atrocity asap!
4925 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
4928 values.c: allocate_repeat_value was not clearing the
4929 optimized_out field.
4930 (value_static_field): minor stylistic fix (wrong macro was used).
4931 valops.c (value_struct_elt_for_address): didn't work for C++
4934 * signame.c (_initialize_signame): Initialize signal names once.
4936 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
4937 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
4938 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
4940 * remote-eb.c: Support user-settable baud rates on the serial port.
4942 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
4944 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
4946 * tconfig/sun3os4: Remove warning about native assembler,
4947 since it also occurs in the xconfig file.
4949 * findvar.c (registers): Allocate some slop after `registers'
4950 to prevent stray accesses from trashing the next variable.
4952 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
4953 on the sun-3, by changing the #ifdef from `sun3' (which is not
4954 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
4955 vars, which happened to follow `registers' in the executable.
4957 * readline/history.c (history_search): Heed gcc-2's advice
4958 and parenthesize && inside ||).
4960 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
4961 tm-29k.c: Insert FSF copyright headers.
4963 * remote-eb.c: Better comments.
4965 * Makefile.dist: Update to 3.91.6.
4966 * TODO: note PREPARE_TO_STORE problem.
4968 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
4970 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
4972 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
4974 * infrun.c (wait_for_inferior, at end): Don't set up
4975 prev_* if the inferior no longer exists.
4977 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
4978 CANNOT_EXECUTE_STACK.
4979 valops.c (call_function): Use it.
4981 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
4983 * inferior.h (PC_IN_CALL_DUMMY): New macro.
4984 infrun.c (wait_for_inferior, 2 places): Use it.
4986 * values.c (value_being_returned): Only use
4987 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
4989 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
4990 right thing for remote-eb.c.
4992 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
4993 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
4995 * blockframe.c: Put get_frame_saved_regs inside #if !defined
4996 (FRAME_FIND_SAVED_REGS).
4998 * findvar.c ({fetch,store}_registers): Check for
4999 REMOTE_{FETCH_STORE}_REGISTER macro.
5001 * findvar.c (get_saved_register): Add argument lval and
5002 change meaning of argument addr.
5003 findvar.c: Change calls to get_saved_register to reflect
5004 new calling convention.
5005 valops.c (value_assign): Use get_saved_register instead of
5006 find_saved_register.
5008 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5010 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
5011 an (uninitialized) pointer to one. Use "&" when passing it
5014 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5016 * coffread.c (getfilename): Use DGUX x_offset and x_name if
5019 * coffread.c (symbol_file_command): Put semicolon after
5021 Put safe_to_init_tdesc_context in #if defined (TDESC).
5022 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
5023 coffread.c: #include <sys/stat.h>.
5024 (read_coff_symtab): Typo: in_source_files -> in_source_file.
5025 Add missing ')' in check for "lc%" and friends. Remove
5027 Declare read_one_sym() at top of file.
5028 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
5029 MC68WRMAGIC can have the same value without causing a duplicate
5032 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
5034 * Allow a Makefile to be built without building the
5035 tm and xm file links that screw up builds in subdirectories.
5036 This is done with `config.gdb none', then you can do things
5037 like `make gdb.tar.Z'.
5038 * tconfig/none: Config file for no target system
5039 * xconfig/none: Config file for no host system
5040 * config.gdb: If no TM or XM files are called out by the
5041 host or target file, don't make links for them.
5043 * cplus-dem.c: Add documentation.
5045 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
5046 simple error, so the user's gdb doesn't crash due to some object
5047 file problem (e.g. somebody is rebuilding the file out from under
5050 * printcmd.c (print_address_symbolic): demangle the symbol.
5052 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
5053 Motorola copyrights in it. Make "make gdb.tar.Z" work.
5054 (alldeps.mak): sort and uniq all results from this; duplicates
5055 hose gdb.tar.Z link building. Remove RCS files from
5056 tconfig and xconfig. Add config files for sun386. Add
5057 a few odd files to OTHERS and HFILES.
5059 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
5061 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
5062 Roll version number to 3.91.5. Make lint work in bindir.
5064 * README: Document cross-debugging and new file structure.
5066 * blockframe.c: Lint. Include "value.h" to declare read_register.
5067 (find_pc_partial_function): remove duplicate line.
5069 * command.h: Lint. Declare error_no_arg and dont_repeat.
5071 * tm-news.h: Remove inadvertently duplicated stuff.
5073 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
5074 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
5076 * config.gdb: Allow `config.gdb host target' form. Clean
5077 up previous change that printed bogus messages when you just said
5080 * core.c: #include "command.h" for lint.
5083 * main.c: Remove some casts of enums. Lint.
5090 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
5092 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
5093 read it from memory. This will allow us to save ptrace calls
5094 eventually. Changed caller single_step too.
5096 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
5097 that we aren't going to use, saving many ptrace calls, especially
5098 when watchpointing or single stepping. Use some #define's for
5100 (store_inferior_registers): Ditto.
5101 (core_file_command): Use some #define's for constants.
5103 * tm-sparc.h: Add #define's for some register numbers, so we
5104 can eliminate the use of random constants in sparc-xdep.c.
5106 * stack.c (frame_command, print_frame_info, up_command,
5107 down_command) Remove frame_changed, since it
5108 causes a bug and doesn't seem to do anything useful. In some
5109 places it was used as a flag, in others as a stack level (?).
5111 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
5112 default is to use the portable (vprintf) version rather than the
5114 * xm-news.h (MISSING_VPRINTF): Add.
5116 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
5118 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
5120 * Remove stuff that forces -Bstatic linking of gdb, and warnings
5121 about linking debugged programs -Bstatic in the sun?os4 config
5122 files in tconfig and xconfig subdirectories.
5124 * main.c (main): Remove unreached exit(0) now that we exit
5127 * Create TODO file for online bug list. There are too many
5128 "little" bugs to keep track of on paper.
5130 * Change Projects file to refer to bug-gdb@cygnus.com
5131 rather than kingdon@ai.
5133 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
5135 * Makefile.dist (VERSION): 3.91.4 now.
5137 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
5138 (condense_misc_bunches): Add sanity check that misc_count is
5139 the same as the number of symbols in the bunch.
5141 * coffread.c: rename init_misc_bunches. Pass an argument
5142 to condense_misc_bunches (a zero).
5144 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
5145 every time we are called; don't rely on our caller to do it.
5146 (add_file): Remove call to init_misc_bunches.
5148 * mipsread.c: Only warn, don't error, if unknown symbol types.
5149 This keeps an old gdb from falling on its face if it sees newly
5150 extended symbol info. Rename init_misc_bunches.
5152 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
5154 * Merge in changes from Per Bothner for DECstations and other
5155 MIPS stuff. The rest is Bothner speaking:
5157 The next message is a merger of Alessando Forin's mips port with
5158 mine. I've tried to use my good if biased judgment to get
5159 the best of both. It *does* need testing.
5161 Some of the changes are general, *not* mips-specific.
5164 Didn't believe in little-endian bit order.
5165 There are still inconsistencies about whether flags
5166 like BITS_BIG_ENDIAN are integer (#if ...) or
5167 boolean (#ifdef ...). I tried to paper over them.
5169 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
5170 Moved some misc_function code that was common to
5171 {dbx,coff,mips}read.c to symtab.c.
5172 In the process, I think I cleaned things up a bit.
5173 At the same time, moved obsavestring and obconcat to symtab.c.
5176 Removed obsolete condense_addl_misc_bunches (use
5177 condense_misc_bunches(1) instead).
5180 Needed to include <sys/dir>, at least on DECstations.
5182 valops.c, mips-tdep.c, tm-mips.h:
5183 Added PUSH_ARGUMENTS macro to support funny argument-pushing
5184 conventions (when STACK_ALIGN is insufficient).
5185 Needed on mips, where doubles need 8-byte alignment,
5186 but ints only need 4.
5189 Removed cruft that was not being used.
5190 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
5193 Print $ before register-names (I think that makes things a little
5195 Never print two instructions, even if one delays.
5196 Removed hex-disassemble set_cmd. (This is not mips-specific,
5197 so I think the argument is whether it is generally worthwhile or not.
5198 I'm inclined to think not, given how easy it is to
5199 convert between radixes in gdb.)
5202 This is basically Alessando's code.
5203 It doesn't use obstacks; I changed it to use obstacks
5204 in a few minor places where using malloc causes a
5205 memory leak. (Probably, more places could/should be changed.)
5206 I added record_misc_function where it was missing.
5207 In symbol_file_command and add_file_command, I tried
5208 to make the code consistent with more recent versions.
5209 Minor sylistic changes in parse_procedure.
5210 Make a .gdbinfo. psuedo-symbol point back to the real
5211 procedure symbol (using the isym field).
5214 This is basically from my port, but with a lot of details
5215 and a number of routines merged in from Alessando's version.
5216 I basically used my code "raw" backtrace (use heuristics
5217 from the actual code, rather than symbol table info) - though
5218 the idea is Alessandro's. I feel my code is a little cleaner
5219 here, particularly in being a little more flexible, such as being
5220 able to handle gcc-produced code (which it now can).
5221 It also doesn't do frame caching (which is not useful
5222 more recent gdb versions).
5223 I also used my code for push_/pop_dummy, more or less.
5224 I tried to incorporate AF's code for testing sigtramp
5225 while backtracing; I probably got it wrong.
5226 Added mips_print_register, which tries to scrunch as much
5227 information as possible on a screen...
5228 Removed the skip-prologue set_cmd. As with hex-disassemble (see
5229 under mips-pinsn.c), I don't see anything mips-specific here,
5230 and I don't see it being all that useful anyway.
5233 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
5234 Use more register names (rather than hard-cases numbers).
5236 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
5238 * Hack up 3.90.11 changes:
5240 * Makefile.dist (depend): parameterize $(GCC).
5241 Add solib.c and solib.o.
5242 (readline): Fix vpath for both absolute or relative SRCDIR.
5244 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
5245 Also, let the part I didn't understand at least compile so
5246 I can test the rest. FIXME.
5248 * dbxread.c: Fix thinko using strcmp.
5249 (init_psymbol_list): declare static.
5250 (partial_symbol_file_open): Comment cleanups better, avoid
5251 cleaning up the string table since the caller will do that.
5252 Move the stat for mod time into symbol_file_command, temporarily.
5253 (There should be a mod time for each symbol file, eventually,
5254 to control its rereading. FIXME.)
5256 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
5257 SunOS, which gives error for shared libs otherwise. (From
5258 Schaefer, probably FIXME needs work for portability.)
5260 * solib.c: Move #include "param.h" to work.
5261 Lowercase all the Uppercase Letters In the Messages.
5262 (find_solib): Clean up inferior_so_name for debug printouts.
5263 Allow no argument, to mean all shared libraries.
5265 * symmisc.c: include param.h to get CLEAR_SOLIB.
5267 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
5269 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
5270 to 3.90.11. ChangeLog entries below are from this.
5272 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5276 * Makefile.dist (HFILES): Add tm-sunos.h.
5278 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5282 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
5284 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
5286 * sparc-opcode.h Added single-operand version of rett.
5288 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5290 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
5291 Put parens around gcc_p in expansion.
5293 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5295 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
5297 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5299 * Changes for Sun shared libraries:
5300 blockframe.c (find_pc_partial_function): If a non-text symbol
5301 is found, set *address = pc - FUNCTION_START_OFFSET.
5302 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
5303 Disable breakpoints instead of giving an error.
5304 source.c (select_source_symtab): Initialize cs_pst.
5305 symmisc.c: Call CLEAR_SOLIB if defined.
5306 symtab.h: Make text{low,high} CORE_ADDR not int.
5307 (psymtab): New field addr.
5309 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
5310 (record_misc_function): Give correct type for N_DATA symbols.
5311 (condense_misc_bunches): do "misc_function_count = j" regardless
5313 Take code which is shared between symbol_file_command and
5314 add_file_command and put it into partial_symbol_file_{open,read}.
5315 Split add_file_command into add_file_command and add_file.
5316 Make psymtab_to_symtab read in the string table if the file
5318 Two new parameters to read_dbx_symtab and start_psymtab.
5319 tm-sunos.h: New file.
5321 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5323 * infcmd.c: Change cont_command to continue_command and "cont"
5326 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5328 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
5330 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
5332 * values.c (USE_STRUCT_CONVENTION): Check for structures of
5333 size 1,2,4,8 rather than size < 8.
5335 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
5336 as necessary, not just once.
5338 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
5340 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5342 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
5344 * tm-news.h: Add CALL_DUMMY_*.
5346 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
5348 * config.gdb: In list_host, list_target, use ${i}, not $i.
5350 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5352 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
5354 * sparc-opcode.h: Change all store floating-point state register
5355 instructions to have the right match & lose fields.
5357 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5359 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
5361 config.gdb: If srcdir != ., create readline directory and
5362 copy a makefile into it.
5364 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
5365 consistency with POSIX.
5367 * breakpoint.c (bpstat_stop_status): Disable watchpoint
5368 when we exit its exp_valid_block.
5370 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
5372 * Makefile.dist: Bump version to 3.91.3.
5374 * Clean up handling of breakpoint commands (somewhat).
5375 Prompted by Tiemann bug report "cont 10" doesn't work any more.
5377 inferior.h: Add breakpoint_proceeded to inferior status struct
5378 and globals; save it and restore it.
5379 (clear_breakpoint_commands): Cleanup, remove old #define.
5381 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
5382 (save_inferior_status, restore_inferior_status): handle it also.
5383 (proceed): Remove earlier code that set breakpoint_proceeded.
5384 It is now set only in clear_proceed_status.
5385 (clear_proceed_status): Cleanup, use bpstat_clear rather
5386 than clear_breakpoint_commands. No callers need the stop_bpstat
5387 between clear_proceed_status and proceed.
5389 infcmd.c: Add breakpoint_proceeded definition and comment.
5390 (cont_command, jump_command, signal_command): Move call to
5391 clear_proceed_status right next to call to proceed.
5393 breakpoint.c (bpstat_do_actions): Avoid clobbering our
5394 caller's argument while running down the chain of breakpoints.
5395 Use new variable "breakpoint_proceeded" to determine when
5396 a command that it executes moves the inferior past the
5398 (bpstat_clear): Handle NULL argument.
5399 (bpstat_clear_actions): Avoid useless call to
5400 breakpoint_auto_delete.
5401 (delete_breakpoint): Clean up bpstat's that are pointing to
5402 the deleted breakpoint from the stop_bpstat chain.
5403 (breakpoint_auto_delete): Simplify.
5405 * Clean up handling of EOF, error on stdin, etc. This was
5406 prompted by a network problem that caused gdb to go into an
5407 infinite loop filling up its malloc'd memory.
5409 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
5410 not clear_breakpoints_commands, which is now gone.
5411 (main): If command_loop returns (e.g. from EOF on stdin), do
5412 a quit_command (looping back to command_loop if quit_command
5413 doesn't really quit).
5414 (command_loop): check result from command_line_input and
5415 exit if it returns NULL, rather than passing the NULL to
5417 (gdb_readline): Free malloc'd result space before returning
5420 * utils.c (query): Handle C-d to mean "yes", just as if the
5421 input was not a terminal. Also avoid infinite loop if EOF
5422 occurs in mid-input-line before newline. This allows
5423 query to be used at EOF on stdin with reasonable results.
5425 * infrun.c (proceed): Set breakpoint_proceeded.
5427 * values.c (value_as_long): Avoid infinite recursion for enums.
5428 (_initialize_values): Fix typo in help msg (kingdon).
5430 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
5431 RL_LIB for linking. This allows -lreadline for linking
5432 and nothing for dependencies, once readline is a real library.
5434 * config.gdb: Jim Kingdon: give useful error message if the
5435 host or target type is not recognized.
5437 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
5438 it just defines it. Dumb, but deal with it.
5440 * Jim Kingdon suggests:
5441 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
5443 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
5445 * Makefile.dist (VERSION): Bump version # to 3.91.2.
5447 * Clean up Bothner's changes.
5449 * blockframe.c (clear_pc_function_cache): New function.
5450 * blockframe.c: remake cache_pc_function_* static.
5451 * dbxread.c (symbol_file_command): remove references to
5452 cache_pc_function_* variables.
5453 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
5454 * printcmd.c: Avoid kludging a global variable (addressprint)
5455 to avoid printing the address of a string twice. Instead,
5456 pass the format letter 's' down low enough that it can be seen
5457 to avoid this problem.
5458 (print_formatted): Pass format arg to value_print.
5459 (restore_addressprint): Remove function.
5460 (do_examine): Avoid hacking addressprint, cleanups and such.
5461 (print_frame_args): Add a comment to a Bothner change.
5462 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
5463 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
5464 to wipe out the values cached in blockframe.c.
5465 * symtab.c (find_method): Add comment saying how big you must
5466 allocate to be "big enough". Per being terse again.
5467 * valprint.c (val_print): Handle format letter "s" to print
5468 strings without addresses. Add comment to vtbl printing code
5469 which casts with wild abandon. Rearrange reference-printing
5471 @0xaddr: value (print w/addressprint)
5472 value (print w/~addressprint)
5473 @0xaddr (parameter lists w/addressprint)
5474 or nothing (parameter lists w/o addressprint)
5476 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
5478 * Merge more changes from Per Bothner:
5480 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
5481 annoying) that I tried to improve it. Here are my suggestions.
5483 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
5486 Do automatic de-reference when taking the address of a reference.
5488 Don't deref_ref when printing parameter lists.
5490 More attempts at treating refernences properly.
5492 In val_print, if deref_ref==0, don't print dangling " = ".
5494 Add COERCE_REF macro, which de-references an REF.
5496 * Merge changes from Per Bothner:
5498 * Fixed (Sony news)-specific configuration problems.
5499 * Fixed other problems with using vanilla pcc and libc (enum problems;
5500 assumption that vsprintf exists).
5501 * Some major speed-ups (finc_pc_partial_function now caches a match;
5502 parsing avoids duplicate symbol_lookup calls).
5503 * Changed handling of baseclasses (no longer use baseclasses field
5504 of struct type, use the first n_baseclasses fields instead).
5505 * Various minor changes/fixes, most C++-related.
5508 Cache the most previous match from find_pc_partial_function.
5509 (Save both low and high ends of matching function's pc range.)
5510 This speeds up the loop of infrun.c:wait_for_inferior quite
5511 a bit, and makes step/next commands much zippier.
5513 Added an enum->int cast (otherwise, some compilers barf).
5515 No longer set baseclass offset to 0, since multiple
5516 inheritance now mostly works.
5517 Added a number of casts, to shut up compiler warnings
5518 (after stabs where made enums, not ints).
5519 When discarding a symbol table (in symbol_file_command),
5520 must clear the cache introduced in blockframe.c.
5521 Don't convert $vtbl_ptr_type to vtbl any more.
5522 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
5523 Mask off sign bit emitted by g++ for virtual table offset.
5524 Set voffset to -1 (not 1) for static member functions.
5526 Changed parsing/lexing of names to avoid doing symbol lookup twice
5527 (once when lexing to determine symbol class, once for real).
5528 Now only call symbol_lookup once. Fields of 'this' win especially big.
5530 Subpress printing addr twice in the case of 'x/s addr'.
5532 lookup_basetype_type is no longer used.
5533 Add find_methods as recursive helper function to decode_line_1.
5534 This allows multiple inheritance to work.
5535 Also, once one or more matches has been found, do not look in
5536 base-classes. (Baseclass methods would be overridden, anyway.)
5538 Removed baseclasses array in struct type.
5539 Instead of using baseclasses[i], use fields[i-1].
5540 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
5541 Changed sign convention of voffset (previous was inconsistent).
5543 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
5545 Used to assume existence of vsprintf. Re-written to not need it
5546 if HAVE_VPRINTF is undefined.
5548 typecmp was too pessimistic. Made it less so.
5550 Don't print space after address.
5551 If vtable points to a misc symbol (with 0 offset), print it,
5552 since that indicates the actual class of the object.
5553 Changed ype_print_derivation_info to use new inheritance
5554 scheme (without baseclasses vector).
5556 In value_primitive_field, fixed some bugs left over from previous set of fixes.
5557 Also, changes needed because TYPE_BASECLASSES were removed.
5559 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
5561 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
5564 If there is no path set, and the symbols don't indicate what directory
5565 a file was compiled in, look in the current directory. But either
5566 a path or a known compilation directory will prevent this.
5569 Three independent bug fixes:
5570 * Remove the #if 0 block that breaks some stuff.
5571 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
5572 adapt gdb to either SunOS 4.0.* or 4.1.
5573 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
5576 Instantiate the class T when looking for methods in it. (Tiemann@sun)
5579 (type_print) Demangle the name being printed.
5580 (type_print_base) Handle botched demangling without coredump (tiemann).
5583 (check_stub_method): Document routine.
5584 (tiemann) fix bug for no-arg functions
5585 Avoid clobbering beyond end of malloc'd storage.
5586 Terminate the argument list properly.
5588 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
5590 * Changes merged by John Gilmore:
5593 In breakpoint_1, use new print_address_symbolic instead
5594 of find_pc_partial_function. (This forces use of assembler-level
5595 addresses, and avoids misleading non-mangled source-level names.)
5597 Generalize ansi argument such that -1 means skip arglist totally.
5598 Removed global variable print_ansi_qualifiers (which made
5599 code non-reentrant), in favor of extra explicit arguments
5600 to internal routines.
5602 Add new helper function print_address_symbolic.
5603 Use find_pc_misc_function instead of find_pc_partial_function
5604 (since we want assembler-level symbols here).
5606 Print unknown function as just "f (...)", not "f (...) (...)".
5607 Use new fputs_demangled explicitly.
5609 Fixed a typing violation (problem: value.h cannot be imported
5610 without renaming many variable in this file).
5611 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
5612 decode_line_1: Moved forward some never-reached code.
5613 Made decode_line_2 skip function prologues correctly.
5615 fputs_filtered should not demangle by default.
5616 Add new fputs_demangled to demangle on demand..
5618 Change value_struct_elt to use value_primitive_field (using recursive
5619 utility function search_struct_field). This allows foo.bar to work
5620 for multiple inheritance (so far only for data fields).
5621 Change check_field in the same way (recursive helper function
5622 to support multiple inheritance).
5623 (Note: there are more of these problems that I haven't fixed.
5624 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
5625 value_of_this: 'this' symbol name is now just "this", note "$this".
5627 Don't print static members.
5628 Avoid printing "members of <type>" if there are none.
5629 Simplified type_print_derivation_info by merging duplicate code.
5630 Remove useless blank lines in type_print_base (ptype command).
5632 Added declaration of new routine value_primitive_field.
5634 Added value_primitive_field which is generalized version of
5635 value_field that can handle multiple inheritance (non-zero offsets etc).
5636 Re-implemented value_field to call value_primitive_field.
5638 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
5640 * infcmd.c -- insert else to avoid 'delete env' coredump when you
5641 delete the whole environment. Karl Berry reported the bug.
5642 * source.c - fix openp to avoid //'s in filenames, which
5643 trigger an Emacs bug causing it to not be able to find files
5644 when running gdb in a window.
5645 * dbxread.c - zap the #if 0 that botches the add-file code.
5646 It seems to work a lot better without all the code commented out.
5648 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
5650 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
5653 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
5655 * Makefile - added a ${CFLAGS} to a couple of entries,
5656 added remote-sa.sparc.c
5657 * added remote.sa-sparc.c, a modification of remote.c
5658 which conducts a dialog directly with the SparcStation prom.
5659 * breakpoint.c, infrun.c, sparcdep.c added
5660 remote_insert_breakpoint(), and remote_remove_breakpoint()
5661 to breakpoint.c instead of directly writing breakpoint instructions.
5662 * sparcdep.c on remote_debugging,there is no need
5663 to remove signle step breakpoint instructions.
5664 * main.c added "-epoch" flag and "int epoch_interface" to main.c
5666 * printcmd.c - epoch interface sends lisp expressions to open up
5667 epoch windows on inspection.
5668 * valprint.c - added arrayprint, and addressprint and made adding
5669 format controls easier
5670 * wait.h added a couple of undef's because we were getting
5671 complaints about WSTOPSIG and WTERMSIG begin redefined.

5741 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
5742 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
5743 when printing the type.
5745 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)

5767 step_resume_break_address != NULL, even if another_trap.
5768 If trap_expected and we enter sigtramp, then set up a
