1 Thu Oct 24 01:32:51 1991 Fred Fish (fnf at cygnus.com)
3 * dwarfread.c: New file for DWARF debugging format support.
5 * elfread.c: New file for ELF object file format support.
7 * procfs.c: New file for SVR4 /proc (process file system) support.
9 * tm-amix.h, xm-amix.h, tconfig/amix, xconfig/amix: New files for
12 * xm-svr4.h, tm-svr4.h: New files for SVR4 support.
14 * xm-m68k.h: New file for host machines with m68k cpu.
16 * Makefile.in: Add elfread.c and dwarfread.c to SFILES_MAINDIR.
17 Add elfread.o and dwarfread.o to OBS.
19 * symfile.h: Add "elf" to list of supported formats in comment.
21 * c-exp.y, defs.h, symtab.h, valprint.c: Add three new builtin
22 types to gdb, builtin_type_long_double, builtin_type_complex, and
23 builtin_type_double_complex. Add and use new TARGET_SHORT_BIT,
24 TARGET_INT_BIT, TARGET_LONG_BIT, TARGET_FLOAT_BIT,
25 TARGET_DOUBLE_BIT, TARGET_LONG_DOUBLE_BIT, TARGET_COMPLEX_BIT, and
26 TARGET_DOUBLE_COMPLEX_BIT, as the sizes in bits of the indicated
27 types on the target machine (ala the existing TARGET_LONG_LONG_BIT).
29 * infrun.c: When using SVR4 /proc interface instead of ptrace(),
30 call proc_set_exec_trap() to setup child to stop at first instruction.
32 * inftarg.c: When using SVR4 /proc interface, call proc_wait()
35 * m68k-tdep.c: Add new routines supply_gregset(), fill_gregset(),
36 supply_fpregset(), and fill_fpregset(), which are machine
37 dependent support routines for SVR4 /proc interface.
39 * utils.c: Add warning_setup() and warning(). Warning() behaves
40 the same as error() except that it returns normally rather than
41 jumping back to command level. Modules that don't want to call
42 warning() for some reason, but want to produce their own warnings,
43 can call warning_setup() to ensure compatibility with the way
44 warning() and error() deal with the terminal.
46 * symtab.c: Make internal errors produce more useful messages.
48 * tm-68k.h: Move code that is duplicated in almost every single
49 m68k based machine's configuration files to this common file.
50 Duplications in the configuration files still need to be removed
53 * infrun.c (child_create_inferior): System V versions must call
54 setpgrp() with no arguments, to comply with prototyping typically
57 * munch: Add support for SVR4 style nm output.
59 * dbxread.c, mipsread.c symmisc.c, symtab.c: Remove the object
60 file specific fields from the partial symbol table structure and
61 replace them with a pointer to private data for each different
62 flavor of object file reader to initialize appropriately.
64 Tue Oct 22 18:04:32 1991 Stu Grossman (grossman at cygnus.com)
66 * infrun.c (wait_for_inferior): Check return value from
69 Mon Oct 21 17:47:03 1991 Stu Grossman (grossman at cygnus.com)
71 * infrun.c (wait_for_inferior): fix stepi/nexti that was broken
72 by my last edit to this routine.

83 * README, TODO, WHATS.NEW: Update.
85 * core.c (core_open): Improve error message for bad file.
86 Pass .reg virtual memory address to fetch_core_registers to help
87 it find the registers in the core-file header.
88 * coredep.c (fetch_core_registers): Take new argument, use it,
89 and pass it to register_addr to locate the block of registers.
90 * xm-mips.h: Update KERNEL_U_ADDR for new scheme. Cleanup a bit.
92 * dbxread.c (read_dbx_symtab, process_one_symbol): Handle
93 Sequent N_FN_SEQ like everybody else's N_FN.
95 * main.c: Circumvent SCO cc bug with #if !!defined(USG).
96 * tm-i386v.h: #endif guck.
97 * xconfig/i386*: Remove -Dgetpagesize()=4096 kludge.
98 * xconfig/i386sco: Add HAVE_STRSTR to avoid ANSI bdeath.
99 * xconfig/tahoe: Add REGEX, which seems to be missing.
101 * coredep.c: Add <sys/types.h> for SCOnix.
102 * dbxread.c (read_dbx_symntab): Avoid coredump on malformed file.
103 * printcmd.c (print_formatted): Flush output before disassembly.
105 Tue Oct 15 20:12:32 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
107 * doc/refcard.tex (sec "Working Files"): consistent metavars and
108 other improvements, due to comments by François Pinard
109 (pinard@iro.umontreal.ca)
111 * doc/gdb.texinfo (appendix "Installing GDB"): changes in
112 configure, and improvenets related to Pinard's refcard comments

131 * i387-tdep.c (double_to_i387): Fix typo for double_to_ieee_extended.
132 * utils.c (_initialize_utils): If !ISATTY, don't paginate.
133 * configure.in, tconfig/decstation, xconfig/decstation: Rename
134 dec3100 to decstation.
136 Mon Oct 14 13:37:50 1991 Roland H. Pesch (pesch at cygnus.com)
138 * doc/gdb.texinfo: Catch up to changes recorded here in ChangeLog

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

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

277 * nindy-tdep.c (nindy_frame_chain_valid): Use lookup_misc_func.
278 (Reported by Mark Peek <mark@imagen.com>.)
280 * solib.c (solib_map_sections): Relocate all sections, even
281 though only the text section's size is tracked. Mark ld_text
282 for eventual elimination as we generalize to N sections.
284 * infrun.c (wait_for_inferior): Don't check if the PC is in a
285 call_dummy if we were stopped by a random signal that is being
286 passed to the program. This produced wierd results when calling
287 functions in the inferior and signals (e.g. SIGALRM) were in use.
289 Tue Sep 24 18:05:30 1991 John Gilmore (gnu at cygnus.com)
291 * infrun.c (IN_SIGTRAMP): Not parenthesized properly.
292 Bugfix from Paul Eggert <eggert@twinsun.com>.

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

397 symtab is not read in.
398 * mips-tdep.c: Remove some unneeded #includes.
399 * xconfig/dec3100: Add HAVE_STRSTR.

510 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
512 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
513 entries are enclosed herein. Not all of these changes
514 have been merged into the master GDB sources -- check the
515 ChangeLog above here for the merge log.
517 Mon Jun 3 17:05:45 EDT 1991
519 m2-exp.y Created. Tested outside of GDB for a few days. Proper
520 operators were added, C specific operators and tokens
521 removed. yylex() revamped to some extent. Still things
522 missing from the grammar, such as sets.
523 Tested for two weeks in GDB v3.5.
525 Tue Jun 11 17:23:48 EDT 1991
527 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
528 so they are built-in. Sort of a hack.
530 Fri Jun 14 12:53:51 EDT 1991
532 m2-exp.y Added range checking for numeric constants. Any numeric
533 constant is assumed to be of builtin type INTEGER unless:
534 (1) it is octal or hexadecimal, in which case it is a
535 CARDINAL; (2) it is too big to fit into an INTEGER, in
536 which case it is a CARDINAL.
537 eval.c Added simple range checking for +, -, and * on integers.
538 Doesn't work very well for *, since 6 * 1,000,000,000 =
539 1,705,032,704, which fails the simple test of result >=
540 first_operand, no matter in what order the operands are.
542 Tue Jun 18 14:11:30 EDT 1991
544 Broke the parser into parts, one containing the C grammar and the other
545 containing code to be shared by all of the grammars.
547 The following files no longer exist:
552 The following files were added:
554 c-exp.y (The C grammar)
555 m2-exp.y (The Modula-2 grammar)
556 parser-code.c (Code that is shared by the above grammar)
560 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
561 now necessary to use the Bison compiler compiler, since it
562 will generate function/variable prefixes other than yy.
564 Tue Jun 18 16:47:49 EDT 1991
566 symtab.[ch] Added the external variable working_lang, than holds the
567 value of the current working language.
568 Added the ennumerated type language_mode, with the values
569 language_auto and language_manual, the former meaning that
570 GDB sets working_lang as needed, and the latter meaning
571 that the value of working_lang is totally under user
573 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
574 REAL, BOOLEAN and CHAR. Also added the type codes
575 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
576 utils.c Added set_language_command and show_language_command to
577 implement the GDB support commands "set language" and
579 expression.h A number of identifiers were added to the type exp_opcode
580 to facilitate Modula-2 builtin functions, integer
581 division, and array indexing.
583 Wed Jun 19 13:25:58 EDT 1991
585 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
586 if the language specified by working_lang requires the use
587 of strict typing of expressions. Eventually, even this
588 will be able to be changed by the user.
589 Added the macro RANGE_CHECK, which evaluates to non-zero
590 if the language specified by working_lang requires the
591 checking of a value against the domain of its type.
592 Eventually, even this will be able to be changed by the
594 language.[ch] Predicates involving types (simple_type, ordered_type,
595 same_type, integral_type, numeric_type, character_type,
596 boolean_type, float_type) are added. These predicates are
597 based on the current value of working_lang, and are handy
600 Wed Jun 19 15:39:34 EDT 1991
602 eval.c Added the function type_array_rank which computes the rank
604 valarith.c Added the funtion value_bool, which when given a integer
605 value.h value (ie. struct value *) as an argument, it returns a
606 boolean value (ie. struct value *) true if that integer
607 is non-zero, and a boolean value false otherwise.
608 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
609 will print out properly.
611 Wed Jun 19 16:36:34 EDT 1991
613 valops.c Added the function value_capitalize, which returns it
614 value.h argument capitalized if its argument is a lowercase
615 letter, or the argument unchanged if its argument is not a
617 valarith.c Added the function range_check_p, which returns non-zero
618 value.h if its value argument is between the integral bounds upper
620 Added the function range_check_enum_p, which makes sure
621 that its value argument is a valid member of the domain of
623 Added the function range_check_range_p, which makes sure
624 its value argument lies between the upper and lower bounds
625 of its type argument, which must be a ranged type.
626 Added the function check_array_index, which range and type
627 checks an index of an array.
628 Added the function value_multi_subscript, which computes
629 array[idx1,idx2...idxN], given a value array and an array
630 of values representing indicies.
631 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
632 unpack_long to work with TYPE_CODE_BOOL and
635 Wed Jun 19 18:04:08 EDT 1991
637 symtab.c Stored pervasive types in a structure and make
638 lookup_pervasive_type() a lookup function that was based
639 on working_lang. If lookup_pervasive_type() returned
640 non-zero, then that value was returned (a fix, since
641 before it simply wouldn't return the pervasive type.)
642 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
643 non-zero if the language specified by working_lang means
644 "conversion" when it says "cast".
645 valops.c Added the function value_real_cast(), which performs a
646 value.h *cast*, not a *conversion*, which is what value_cast()
647 does when it can. In particular,
648 value_cast(<float_type>,4) = 4.0, while
649 value_real_cast(<float_type>,4) = some mess.
650 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
651 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
652 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
653 and MIN on integral types. *NOTE*: These are currently
654 hardcoded to work only if there are 8 bits per storage
656 eval.c Made logical functions call value_bool to return a
657 properly typed boolean value, based on working_lang.
659 Thu Jun 20 11:55:27 EDT 1991
661 valprint.c Types now print out in a Modula-2 fashion. This works for
662 the cases when the type is printed out step-by-step, that
663 is, it doesn't work when the name of a structured type
664 (which includes the keyword "struct", etc.) is simply
666 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
667 since type specifications in C and Modula-2 are very
668 different. The C printing of a type is very recursive,
669 whereas in Modula-2 it is generally very simple. C has
670 type prefixes and suffixes, which have no real analogue in
671 Modula-2. Maybe type_print() should call a language
672 specific type printer. This is also advantageous if we
673 compile GDB to exclude some of the languages. We'll just
674 leave those functions out.
676 Thu Jun 20 16:57:10 EDT 1991
678 dbxread.c When reading the complete symbol table in (via
679 psymtab_to_symtab()), the number and types of function
680 arguments are added to a function type. define_symbol()
681 calls add_param_to_type() to accomplish this.
682 Assumption: when we come across a function definition
683 (N_FUN symbol with an 'f' or 'F' in the name), its
684 arguments will appear before another function definition.
685 When a function is found, a pointer to its type is placed
686 in the global in_function_type. Changes that
687 add_param_to_type() makes are to this global.
688 valprint.c The type of a function now includes (for Modula-2) the
689 types of its parameters.
690 eval.c Type checking and a check for the proper number of
691 arguments is now done for function calls. Not sure of the
692 impact this has on C++ member function yet.
694 Thu Jun 20 19:58:48 EDT 1991
696 valprint.c Rewrote the type printer. Broke it into two language
697 specific parts, adding the functions type_print_m2() and
699 An unfortunate consequence is this: if you debugging a C
700 program in Modula-2 mode (why?), info types does not work
701 well with regular expressions, since the types are printed
702 out in Modula-2 terminology, but stored in C terminology.
703 language.[ch] Added the functions new_type_last(), type_keyword(), and
704 type_sep() to aid in the printing of typedefs.
705 symtab.c Made the printing of typedefs as language independent as
706 possible through calls to new_type_last(), type_keyword(),
709 Fri Jun 21 11:50:26 EDT 1991
711 dbxread.c Check all incoming ennumerated types. If it looks like
712 Modula-2's BOOLEAN type, then change the type_code of the
713 type to TYPE_CODE_BOOL so we can process it as a boolean
715 valprint.c Replaced some of the 0x%x with calls to sprintf and
716 hexformat() in val_print().
717 language.[ch] Added the function hex_to_string(), which converts its
718 integral argument to a hexadecimal number (format is
719 language based) and returns the result as a string.
721 Mon Jun 24 12:25:07 EDT 1991
723 valprint.c Some functions call type_print_1() directly, instead of
724 value.h using type_print(), so they can specify where (column) to
725 print things. Since type_print() takes care of language
726 dependence, that needs to be called first. Added a
727 parameter depth to type_print() (so it is now like
728 type_print_1). Changed type_print to type_print_at, and
729 made type_print a macro that passes a depth argument of
731 symmisc.c Changed all calls to type_print_1 to calls to
733 Makefile.dist Made it possible to build GDB for a specific set of
734 depend languages. Do this by passing a definition for the macro
735 LANGS to make. LANGS should be a string containing a
736 space-separated list of language names (ie. LANGS="c m2").
737 The default is to build all languages. Note that grammar
738 files must follow the naming convention of <lang>-exp.y.
739 gdb.lang This holds the current value of the LANGS macro. It is
740 examined every time make is called, and is updated if
742 eval.c Added #ifdef _LANG_<lang> to these files.
743 expread.c Still need to add them to dbxread.c and coffread.c.
751 Mon Jun 24 16:33:11 EDT 1991
753 language.[ch] Added the functions hexformat_pre() and
754 hex_to_string_pre(), which take a prefix argument to
755 include in the format string. Thus, hexformat_pre("08") will
756 return "0x08x" (if the working language is language_c).
757 Made hexformat() and hex_to_string() calls to the above
758 with "" as the prefix argument.
760 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
761 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
762 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
763 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
764 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
765 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
766 valprint.c, vax-pinsn.c
768 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
769 calls to hexformat() and hex_to_string(). Format strings without
770 the leading "0x" were ignored.
772 depend Updated to take the above into account.
775 Tue Jun 25 15:27:18 EDT 1991
777 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
778 and type_check_t to keep track of the current state of
779 range and type checking.
780 main.c Added the variables range_mode, range_check, type_mode,
781 and type_check to record the current state of range and
782 type checking. Added initialization code to main().
783 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
787 Tue Jun 25 17:57:08 EDT 1991
789 dbxread.c process_one_symbol() updates the variable (enum language)
790 source_lang based on the extension of the filename
791 contained in the N_SO sybmol that started this symtab.
792 When end_symtab() is called, the value of source_lang is
793 put into the language field.
794 stack.c select_frame() sets working_lang (and possibly type_check
795 and range_check) to the language field of the symtab
796 associated with the frame that is selected if working_mode
797 is language_auto. If working_mode is language_manual, a
798 warning is printed and working_lang is not set.
799 language.c Added the function set_type_range(), which sets the value of
800 type_check and range_check (if their modes call for
801 automatic setting) based on the current value of
802 working_lang. A non-zero argument will cause the current
803 settings to be output.
806 Wed Jun 26 14:51:40 EDT 1991
808 eval.c Added range checks on assignment.
809 m2-exp.y Added the grammar for sets to the language. Currently,
810 these do not do anything except print an error message.
812 Wed Jun 26 17:01:04 EDT 1991
814 m2-exp.y Added the ability for parse_number() to parse negative
815 numbers. A global flag is set upon encountering a unary
816 minus. This was done to make, for example, 1 parse as a
817 CARDINAL, and not as an integer, per Wirth's examples in
818 Programming in Modula-2 ed.4.
819 valprint.c Added support for "set radix 2" by then setting
820 output_format to 't'.
821 eval.c Implemented range checking on subrange types. Added calls
822 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
823 Implemented MIN and MAX for ennumerated types. The
824 minimum value of an ennumerated type is defined by Wirth
825 as the first identifier, and the maximum as the last.
826 m2-exp.y Made octal numbers ending with "B" be characters and those
827 ending with "C" be numbers, per Wirth's book. (p. 34)
829 Thu Jun 27 14:11:52 EDT 1991
831 stack.c select_frame() now only sets working_lang, it does not
832 notify the user. If working_mode is language_manual, then
833 a warning is issued once.
834 main.c At the end of each call to execute_command(), working_lang
835 is checked against the local static (enum language)
836 current. If they differ and working_mode is
837 language_auto, the new settings of language, type and
838 range checking are printed out.
839 stack.c Modified frame_info() to include the language of the
840 current frame in the output of "info frame".
841 language.[ch] Added the function language_str() which returns the name
842 of the current language.
844 Fri Jun 28 15:33:14 EDT 1991
846 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
847 the language. INCL and DECL currently cause an error,
848 since sets are not implemented yet. INC and DEC are
849 implemented as PREINCREMENT/PREDECREMENT with one
850 argument, and as ASSIGN_MODIFY with two arguments.
851 eval.c Added type checking to the above cases.
852 value.h Added not_lval_constant to the lval_type ennumerated type.
853 not_lval_constant means that the value is a constant
854 value; that is 3 or 'a' or TRUE, not as in a constant
855 identifier. This is used to help coerce numbers such as 3
856 to either signed or unsigned numbers.
857 valops.c Added the function value_coerce_constants() which coerces
858 constant integers as following: if one is a constant and
859 the other is not, the constant's type is set to the type
860 of the other argument. If both are constants and one is
861 signed, the other is converted to a signed constant.
863 Sat Jun 29 17:26:29 EDT 1991
865 valarith.c Added a better range checker. It now checks range
866 (successfully) on integral operations [+-] (signed and
867 unsigned) for any C sized type. Still does not work well
869 int_in_size() returns an integer that is coerced to fit into
870 specified number of bytes.
872 Mon Jul 1 13:04:14 EDT 1991
874 language.[ch] Added the function binop_result_type(), which returns the
875 builtin (struct type *) type that would be the result of a
876 binop on the two values V1 and V2.
878 Wed Jul 3 19:22:53 EDT 1991
880 source.c Extended source_info() to include the source language in
881 the output from "info source".
883 Fri Jul 5 13:48:52 EDT 1991
885 utils.c Moved the support functions for the GDB set/show commands
886 dealing with language into language.c.
887 language.c Added the function language_info(), which displays info
888 about the current working language, type and range check
889 settings. Called via the GDB command "info language".
890 Added an initialization routine _initialize_language(),
891 that sets defaults for the language, type and range
892 variables and sets up the new GDB commands.
893 main.c Language setup moved to language.c.
896 Mon Jul 8 10:10:22 EDT 1991
898 valarith.c Debugged the range checker for arithmetic. Still does not
899 work for multiplication very well.
901 Mon Jul 8 12:40:37 EDT 1991
903 language.[ch] Added the function value_true() which returns non-zero if
904 its argument represents a boolean true value.
905 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
906 check the truth of an expression.
908 Thu Jul 11 12:51:34 EDT 1991
910 language.[ch] Added the predicate structured_type(), which returns
911 non-zero if the argument is a structured type.
912 Added the predicate pointer_type(), which returns non-zero
913 if the argument is a pointer type.
914 eval.c Added the ability to do addition and substraction on
915 pointers and integers. This case simply bypasses the
918 Thu Jul 11 14:41:42 EDT 1991
921 Added the symbol N_DEFD (0x4a) which is a definition
922 module dependency that is used by the GNU Modula-2
923 compiler and the linker. It is not important to GDB,
924 except that [dbx|coff|mips]read.c should ignore these
927 Fri Jul 12 16:07:00 EDT 1991
929 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
930 0 in val_print(). Also added statements to the else part
931 to coerce type (argument to val_print) to a pointer type
932 if it is an "array of unspecified length".
933 valops.c Added the function value_m2_string(), which returns a
934 (value) value which is a constant string, whose type is
935 (ARRAY [0..n] OF CHAR). The length field of the type
936 structure is set to zero, so it will be interpreted as an
937 "array of unspecified length".
938 stack.c Moved the language/frame mismatch check to
939 main.c:execute_command().
940 main.c The working language is recorded each time
941 execute_command() is executed. If working lang has
942 changed during its execution, then the new
943 language/type/range info is printed out for the user. If
944 the working language does not match the language of the
945 frame, a warning is issued.
947 Sat Jul 13 16:16:39 EDT 1991
949 eval.c Moved all the type-checking stuff for operators to
950 language.[ch] language.c. This is so we can keep language-specific
951 stuff (like for what type operators are defined) in
953 language.[ch] Added the function binop_type_check(), which checks to see
954 if its two (value) arguments are type-compatible with its
955 opcode argument. The opcode should represent an operation
956 involving an operator. Also added the macro function
957 unop_type_check, which calls binop_type_check with a
958 NULL second argument.
959 expprint.c Added Modula-2 operators to the op_print_tab, so info
960 expression.h break works correctly. Also added "op_string", which
961 returns the string corresponding to the (enum exp_opcode)
962 opcode that is its argument.
965 Sat Jul 13 18:26:18 EDT 1991
967 coffread.c Added code to record the type of function arguments with
968 each paricular function. Code is very similar to that
970 dbxread.c Moved add_param_to_type() to symtab.c
971 symtab.[ch] Added function add_param_to_type() from dbxread.c
973 *** NOTE: The above additions have not been tested.
975 Mon Jul 15 12:50:47 EDT 1991
977 langauge.[ch] Added the functions type_error and range_error, which work
978 like error() except if the type/range mode is set to
979 *_mode_warn, then they do not do a return_to_top_level(),
980 but merely print a warning.
981 Also changed [set|show]_[type|range]_command() to support
982 the new "warn" feature.
984 Thu Jul 18 17:50:54 EDT 1991
986 mipsread.c Added code to record the type of function arguments with
987 each particular function. Code is very similar to that
990 *** NOTE: The above additions have not been tested.
992 Fri Jul 19 11:19:10 EDT 1991
994 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
995 UMIN_OF_SIZE, which when given a size of a numeric type,
996 return the maximum and minimum value it can hold. UMAX...
997 and UMIN... return the result for unsigned types.
998 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
999 struct types. They call above macros.
1000 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
1001 avoid a name conlict with the above.
1002 c-exp.y Added range checking on numeric constants in
1003 parse_number() for completeness.
1004 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
1005 return 0 if working_lang is not language_c.
1007 Thu Aug 8 14:17:22 EDT 1991
1011 breakpoint.c Documentation strings of some commands changed to
1012 eliminate the references to the C language where
1015 Tue Aug 13 15:48:03 EDT 1991
1017 m2-exp.y Added qualified identifiers to the grammar. The semantics
1018 are slightly different from those of the GDB operator ::
1020 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
1021 type_exp, where type_exp is any valid type expression.
1023 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
1024 printcmd.c Modified ptype_command() so it actually parses the input
1025 (necessary for type expressions with scope qualifiers).
1026 Added the function ptype_eval() which expects an
1027 expression composed of one OP_TYPE element.
1028 *.[ch] Replaced all occurences of parse_c_expression with
1030 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
1032 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]

1048 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
1050 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
1051 chars_per_line is at maximum (user typed `set width 0'). Fix
1052 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
1054 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
1056 * coredep.c: include ptrace.h where necessary.
1057 * mipsread.c(parse_lines): fix unsigned char problem that was
1058 messing up line numbers on SGI's and possibly other MIPS based
1060 * infrun.c (child_create_inferior): use better test to check
1061 return val from setpgrp().
1062 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
1063 for sgi/irix support.
1065 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
1067 * mipsread.c (parse_symbol): Put non-static procedures
1068 in the global block.
1070 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
1072 Patch together `text_start' and `text_end' for 29K port.
1074 * exec.c (exec_command): If NEED_TEXT_START_END, define the
1075 variables and set them based on the exec file.
1076 * am29k-tdep.c: declare text_start.
1077 * valops.c (call_function_by_hand): declare text_end.
1079 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
1080 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
1081 because machines that do this will also have to know to
1082 set NEED_TEXT_START_END. Besides, it was a redundant way to
1084 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
1085 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
1086 NEED_TEXT_START_END.
1088 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
1090 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
1092 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
1093 Pass MUNCH_DEFINE to munch whenever we run it.
1094 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
1095 format string; use 0x%x instead.
1096 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
1097 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
1098 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
1099 * inflow.c: Handle `short' process group IDs.
1100 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
1101 and check for ptrace errors.
1102 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
1103 (coff_symfile_init): Initialize text_bfd_scnum.
1104 (read_coff_symtab): Use it to find the text [and absolute?] sections.
1105 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
1106 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
1107 Merge target arm case with other "easy" cases. Add target
1108 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
1109 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
1111 * minimon.h, remote-adapt.c, remote-mm.c: Add.
1112 * munch: Cope with RT/PC putting fns in data segment.
1113 Restore ability to override `nm' by specifying MUNCH_NM.
1114 * xconfig/rtbsd, xconfig/ultra3: New host systems.
1115 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
1116 and remote-adapt. Remove encapsulated coff #define's (the
1117 support should go in BFD, and gdb shouldn't know or care).
1118 * tconfig/a29k-kern: Same, but for remote kernel debugging.
1119 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
1120 * tm-29k.h: Update BADMAG (though it should go away).
1121 Allow the register definitions to be overridden in another
1122 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
1123 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
1124 DUMMY_SAVE_GR96, for handling kernel calling conventions
1125 that use GR64+ rather than GR96+.
1126 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
1127 remote debugging of Ultra3 kernel. Includes tm-29k.h and
1128 overrides various things.
1130 * remote-mm.c (mm_attach, mm_wait): Handle attach like
1131 child_attach does, making a clean stop in the newly attached
1133 * remote-eb.c: Lint.
1135 * coffread.c: Make coffread independent of any particular
1136 variant of COFF. Avoid #include-ing any particular one except
1137 internalcoff.h. BFD now passes key values for symbol reading
1138 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
1139 and the symbol masks and shifts); use them.
1140 Remove obsolete end_of_text_addr.
1142 * exec.c: Remove unused include files.
1144 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1146 * Makefile.in (documentation targets): Pass $(M4).
1147 Bugfix from eggert@twinsun.com (Paul Eggert).
1149 * stack.c (down_silently_command): Check for stack existence.
1151 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1153 * Makefile.in (VERSION): Update to 4.0.3.
1155 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1157 * core.c (core_file_command): Print frame at coredump with
1158 its level number, by calling print_stack_frame.
1159 * frame.h: Add selected_frame_level, print_stack_frame.
1160 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
1161 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
1162 Change print_sel_frame and print_selected_frame callers to
1165 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
1166 * symfile.c (free_named_symtabs): Ditto.
1167 * main.c (main): wrap_here needs an arg.
1168 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
1169 (solib_add): Avoid noise.
1170 (solib_create_inferior_hook): Lint.
1171 (sharedlibrary_command): Move dont_repeat to here.
1172 * utils.c (error): Call wrap_here to force buffered output.
1174 Small patches from Peter Schauer:
1176 * coffread.c (start_symtab): Free any existing line_vector before
1178 (read_coff_symtab): Ditto for type_vector.
1180 * source.c (lines_to_list): New variable, replacing function.
1181 (all uses): Use as variable.
1182 (_initialize_source): Add 'set listsize' and 'show listsize'.
1183 * utils.c (lines_to_list): Remove function.
1184 * stack.c (print_frame_info): Use as variable.
1185 * defs.h (lines_to_list): Remove declaration.
1187 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1189 * breakpoint.c (insert_breakpoints): Restore warning about
1190 the program might be running in another process, but only for
1191 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
1192 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
1194 * utils.c (error): if error_pre_print is set, print the string
1196 * main.c (main, print_gnu_advertisement, print_gdb_version):
1197 Reformat legalese so it always prints, but acts as an "I'm here"
1198 message while symbols are being read. If any errors occur,
1199 print a few newlines to set off the message and start it at the
1200 left margin. Remove mention of "help" command, and don't yak
1201 about symbol reading.
1202 (catch_errors): Error string is now printed first in case of
1204 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
1205 suggest the "help" command.
1207 * Makefile.in (VERSION): Set to 4.0.2.
1209 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
1211 * .gdbinit: Remove useless "rr" command. Set complaints
1212 to 1 for people debugging gdb.
1214 * breakpoint.c, remote-vx.c: Reword strings printed by
1215 catch_errors callers.
1217 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
1219 * WHATS.NEW: "history write -> history save". Doc "write on/off".
1220 (Fix from kenc@viewlogic.com.)
1222 Fix some infrastructure to be able to cope with host and target
1223 machines with different sized basic types (ints, ptrs, etc).
1224 (Idea from pierre@la.tce.com (Pierre Willard).)
1226 * values.c (value_from_longest): Rename from value_from_long.
1227 Handle pointer types as well as integers, so that targets with
1228 different pointer sizes from the host can be accomodated.
1229 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
1230 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
1231 uses of value_from_long to value_from_longest.
1232 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
1233 the correct pointer type to value_from_long{est}.
1235 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
1237 * remote-vx.c: Remove obsolete code for calling functions via
1238 vxworks kludge interface (it referenced value_from_long).
1240 * valops.c (value_string): Find malloc with lookup_misc_func, not
1243 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1245 Make writing to files work properly. (Fixes to BFD are also needed.)
1247 * core.c (core_open): Open file ourselves, read or r/w, depending on
1248 write_files. Use bfd_fdopenr.
1249 * gdbcore.h (write_files): New variable.
1250 * exec.c (write_files): Define variable, add set&show for it.
1251 (exec_file_command): Use write_files to open for read or r/write.
1253 Make shared library reading happen automatically. These changes
1254 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
1256 * inferior.h (stop_soon_quietly): Add to exported variables.
1257 * infrun.c (child_create_inferior): call solib hook, if defined.
1258 (child_attach): call solib hook, if defined.
1259 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
1260 (find_solib): Use lookup_misc_func rather than hand-rolled.
1261 (symbol_add_stub): New stub for catch_errors.
1262 (solib_add): Avoid output if !from_tty. Catch errors rather
1263 than just calling symbol_file_add and bombing.
1264 (solib_create_inferior_hook): Interface with the target process
1265 to let it read and alloc shared libs, then figure out what it did.
1267 * core.c (validate_files): Fix typo, soften warning.
1268 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
1270 * utils.c (fputs_demangled): Avoid duplicate printing if
1271 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
1273 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
1274 (Fix from pierre@la.tce.com (Pierre Willard).)
1276 * main.c (catch_errors): Change argument to a char * from an int,
1277 since a char * can point to a struct full of glop, but an int
1278 is not guaranteed to be able to hold a pointer.
1279 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
1280 breakpoint_re_set_one, breakpoint_re_set): Adapt.
1281 * core.c (core_open, solib_add_stub): Adapt.
1282 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
1284 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1286 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
1287 by adding .NOEXPORT target.
1289 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1293 * Makefile.in (VERSION): Roll to 4.0.
1294 (gdb.tar.Z): Make refcard.ps as well, for shipment.
1296 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1298 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
1301 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
1304 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
1306 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
1307 reflect above name change
1309 * WHATS.NEW: correct pointer to refcard.
1311 * doc/gdb.texinfo: update New Features, Installing
1313 * doc/gdbint.texinfo: add short description of configure +template
1315 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1317 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
1319 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
1321 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
1322 tar file, add dependencies for referenced doc files.
1324 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
1326 * coffread.c, symfile.c, stack.c: saberized.
1328 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1330 * doc/refcard.tex: permuted Essential Commands sec
1332 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
1334 set/show symbol-reloading
1335 default set complaints 0
1337 RET-repeat disabled after prompted long displays
1338 processID (attach) interpretation of 2nd GDB cmdline arg
1340 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
1342 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
1343 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
1344 breakpoint.c, main.c: lint.
1346 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1348 Install new configuration scheme for GDB and friends.
1350 * config.sub: Translate ordinary names to three-part names.
1351 * configure: Use three-part names internally.
1352 * configure.in: Translate three-part names to filenames.
1354 * README, WHATS.NEW: Update for gdb-4.0.
1355 * Makefile.in: Roll VERSION to 3.99.
1357 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
1359 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
1360 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
1361 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
1362 to single structures rather than arrays; when passing
1363 their address, use &. This avoids trouble with bdead compilers.
1364 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
1365 instead. This avoids portability headaches.
1366 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
1368 * source.c (open_source_file): Avoid ANSI const bdeath by
1369 skipping declaration and then casting result value.
1370 * tm-hp300bsd.h: Clarify comment.
1371 * utils.c (strstr): Result is const char *; ANSI bdeath.
1372 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
1373 since system include file defines it differently from "defs.h",
1374 though the two are equivalent for our purposes.
1375 * tconfig/hp300bsd: Add m68k-tdep.o.
1377 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1379 * tconfig/sun*4: Remove warnings about system assembler.
1381 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1383 * mcheck.c: Avoid warning about undeclared abort fn.
1384 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
1385 it causes recursive calls to error() when used in cleanups.
1386 To do so requires that we make it a function, so we do.
1387 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
1388 * utils.c (do_cleanups): Remove the current cleanup from the
1389 chain *before* calling it, in case error() is called from it.
1390 The result won't be pretty, but won't be an infinite loop either.
1392 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
1394 * dbxread.c (read_struct_type): Grok anon structs for C++.
1395 (vb_name, vptr_name): Null terminate these strings.
1397 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1399 Minor bug fixes from BSD Net2 gdb:
1401 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
1402 returns 0, there is no previous frame.
1403 * breakpoint.c (commands_command): If !from_tty, don't call
1404 input_from_terminal_p().
1405 * dbxread.c (record_misc_function): Speed up slightly.
1406 (compare_psymbols): Ditto.
1407 * infcmd.c (do_registers_info): Take a second argument to
1408 determine whether to print float registers. "info registers"
1409 does not do so anymore. "info all-registers" does, now.
1410 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
1412 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
1413 * inflow.c (initialize_inflow): Set tflags_ours correctly.
1417 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
1418 executing_breakpoint_commands if we are interrupted by error.
1419 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
1420 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
1421 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
1422 catch_errors() so we can setup the frame regardless of whether
1423 the shared libs work.
1424 * ieee-float.c (double_to_ieee_extended): Get exponent from
1425 right place in little-endian systems. From John Carey.
1427 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1429 * main.c: Remove unused terminating_signals and catch_termination().
1430 (long_options): Terminate with a zero element.
1431 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
1432 (gdb_readline): Make call-compatible with readline.
1433 (init_signals): Improve comments re vfork vs. signal.
1435 * utils.c (prompt_for_continue): Use new gdb_readline().
1436 If we prompt for continuation, we don't let CR repeat the previous
1437 command, once we get back to a prompt. It's too easy to keep
1438 hitting CR, expecting "--more--" prompts, and have some long
1439 command start repeating on you.
1441 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1443 * blockframe.c (frameless_look_for_prologue): Speed up by
1444 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
1445 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
1446 Define two variants, one faster.
1447 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
1448 and return zero, rather than giving an error.
1449 (setup_arbitrary_frame): Initialize the PC in the new frame.
1450 (skip_prologue): Add a second arg saying whether we're just
1451 checking for a frameless function or not.
1453 * core.c (core_open, core_close, core_xfer_memory): Move
1454 section table pointers and bfd* into the target_ops.
1455 (core_open): Allow errors in shared lib reading, etc.
1456 (core_files_info): Describe shared library sections.
1458 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
1459 exec_files_info, set_section_command): Move section table
1460 pointers and bfd* into the target_ops.
1461 (add_to_section_table): Add BFD to section table.
1463 * target.c (target_xfer_memory, target_info): Pass target to
1464 xfer_memory and target_info functions.
1467 * gdbcore.h: Move struct section_table.
1468 * target.h: New home of struct section_table.
1470 * solib.c (solib_add): New argument is the target_ops whose
1471 section list is to be added to, if any. Reallocate the
1472 sections in that target to add any that come from shared libs.
1473 (throughout) so_sections renamed to sections.
1474 (solib_xfer_memory): Deleted.
1475 * tm-sunos.h (SOLIB_ADD): Add target argument.
1476 (SOLIB_XFER_MEMORY): Delete.
1478 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1479 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
1480 from target_ops. It's the same on all targets. Add two section
1481 pointers to target_ops.
1483 * stack.c (find_relative_frame): Dump ancient algorithm for
1484 "down", just use handy "next" pointers.
1485 (frame_command): Don't error if there is no stack; let user
1488 * inflow.c (new_tty_prefork, new_tty): New prefork routine
1489 modifies static state in the parent process; new_tty itself
1490 runs in the child and modifies the child's file descriptors
1491 to match the saved static state.
1492 * infrun.c (child_create_inferior): Call new_tty_prefork,
1495 * infptrace.c (child_xfer_memory): Add ignored target arg.
1496 * remote-eb.c (eb_xfer_inferior_memory): ''
1497 * remote-nindy.c (nindy_xfer_inferior_memory): ''
1498 * remote-vx.c (vx_xfer_memory): ''
1499 * remote.c (remote_xfer_memory): ''. Rename from
1500 remote_xfer_inferior_memory.
1502 * main.c (main): Only try to attach "corefile" argument if
1503 it starts with a digit.
1505 * symfile.c (symbol_reloading): New "set/show" variable.
1506 (symbol_file_add): Shorten message about symbol reading.
1507 (add_symbol_file_command): Merge with add_syms_addr_command,
1508 since this should work on all targets now.
1509 (stop_whining): Default to zero, to shut up complaints
1510 about bad symbol tables on many systems.
1511 (free_named_symtabs): Just exit unless symbol_reloading.
1513 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
1514 and add comment explaining shared library screw.
1516 * source.c: #if defined => #ifdef.
1518 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1520 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
1522 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1524 * doc/rdl-apps.texinfo: provide default readline-appendix finder
1525 (doc/Makefile knows how to make one for local config)
1527 * Makefile.in: use doc/Makefile for doc targets
1529 * doc/Makefile: GDB documentation now has its own Makefile
1530 doc/refcard.tex: renamed from "gdbrc.tex"
1531 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
1532 doc/gdbint.texinfo: add markup in "Cleanups" chapter
1535 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1537 * values.c (baseclass_addr): When reading target memory, use the
1538 length of the basetype, not the upper type. We've only malloc'd
1539 enough space for the basetype, leading to errors in free().
1541 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
1542 ends up as a function specially, since we know the actual type of
1543 the pointed-to address. This (somewhat) fixes display of
1544 expressions that include misc_function_vector names. Try `cond 1
1545 !strcmp("a","b")' then `i b'.
1547 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
1548 The child can be proceeded from inside wait_for_inferior in
1549 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
1550 getting skipped in that case.
1552 * expprint.c (print_subexp): Use filtered output, since the
1553 subroutines we call use it, otherwise the output is horribly
1554 mangled, since output of wrappable stuff comes out late.
1556 * Makefile.in: Bump VERSION to 3.98.1
1558 * infrun.c (child_create_process): Use execlp to find the
1559 shell to exec our target program. This requires some fiddling
1560 with `environ' since there is no execlpe().
1562 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1564 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
1565 Minor rearrangement of refcard permits two new make targets--
1566 gdbrc.dvi DVI output for refcard, using CM fonts
1567 gdbrc.ps PostScript refcard, using PS fonts
1569 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1573 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
1574 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
1576 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1578 * doc/gdb.texinfo: last changes for release.
1579 Minor typo and formatting fixes; incorporated most fixes remaining from
1580 filed mail commenting on earlier drafts.
1582 Added warnings: pipes don't work in run command;
1583 conditions are converse of assertions;
1584 step over fn without debug info goes to next fn;
1585 vars may have "wrong" values near fn entrance, exit
1587 Added example from Kingston on printing repeated nonadjacent values
1589 Added explicit mention that in Emacs gdb mode C-c and C-z are like
1590 shell mode for signals
1592 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
1593 doesn't sound so much like its parent "Stopping and Continuing"; also
1594 moved entries on continue to top of section, so they don't get lost.
1596 Improved installation directions in appendix, added manual formatting
1599 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1601 * configure.in: Remove xm.h and tm.h even if we aren't linking
1602 new ones, so "./configure sun4; ./configure none" does the right
1603 thing. Assume that alldeps.mak and depend are already built in
1604 srcdir, and avoid running "make" (particularly "make depend",
1605 which involves "gcc") from inside configure. Build Makefile
1606 directly rather than building Makefile.conf first.
1607 * configure: Regenerate with above changes.
1608 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
1609 to 3.98. Revise gdb.tar.Z procedure to produce a file
1610 called gdb-$(VERSION).tar.Z but which unpacks into a
1611 directory called "gdb". Move non-source files out of
1612 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
1613 (depend): Don't try to do "gcc expread.y".
1614 (expread.o): Update dependencies by hand.
1616 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1619 Fixed a variety of small typos that prevented info from formatting
1620 cleanly; altered too-long heading for GPL Appendix, as discussed
1621 w/RMS; Changed date on cover to July 91.
1623 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1626 (1) Applied some fixes due to comments from Larry Breed (easier ones
1627 through chapsec 5.2)
1628 (2) Eliminated use of @footnote---had my doubts about it anyways, and
1629 it's broken in latest texinfo
1630 (3) Introduced *some* use of [] for optional arguments, where
1631 explanation is not simpler by listing cmd w arg and cmd w/out arg
1632 separately. Still not using @deffn.
1633 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
1634 couple of headings are too long. Need patches to texinfo or revision
1637 * Partial update to README (which still needs work for this
1638 release!): (1) use of configure corrected for new script,
1639 (2) "make gdb.dvi" and "make gdb.info" mentioned.
1641 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
1643 * symtab.c (lookup_symbol): Don't complain right off about
1644 no debug symbols; use the misc function vector first.
1645 (list_symbols): Use misc function vector to find symbols
1646 that don't have debug info, and print them.
1647 (find_pc_symtab): Temporarily avoid fatal() when psymtab
1648 PC range doesn't match symtab PC range, as it does on the
1649 MIPS because our symtab reading isn't perfect.
1651 * dbxread.c (dbx_symfile_read): Make warning about
1652 "no debug symbols" slightly nicer.
1654 * source.c (select_source_symtab): If "main" symbol exists,
1655 but decode_line_spec can't find line info, don't just return
1656 a zero; try other source symtabs or give an error.
1658 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
1659 their low addresses first, then rip through fixing high addrs.
1661 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
1662 <runene@ifi.uio.no>.
1663 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
1665 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1667 * Minor, mostly mechanical, cleanup of doc subdir for clean
1668 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
1669 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
1671 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
1673 Mostly MIPS and general symbol-reading fixups.
1675 * doc/gdbint.texinfo: Add documentation on symbol-reading
1678 * mipsread.c: Remove kludges around #include "ecoff.h".
1679 Remove redefinitions of a_magic, etc, no longer used.
1680 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
1681 Fix global overview comments to match symfile.c protocol.
1682 (mipscoff_new_init): Eliminate cur_hdr if we have one.
1683 (mipscoff_symfile_read): Eliminate unused code. Avoid
1684 sorting all the symtabs, when all we have read here is psymtabs.
1685 The symtabs are sorted as they are created anyway. Tell
1686 condense_misc_bunches whether we're mainline.
1687 (psymtab_to_symtab_1): Pass filename when recursing, to make
1688 stack trace more informative.
1689 (parse_partial_symbols): Assume cur_hdr as argument.
1690 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
1691 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
1692 the TYPE_NAME of char *, since that's done in symfile.c.
1693 (free_numargs, parse_symbol, add_symbol, add_block,
1694 shrink_linetable): Declare these fns void.
1695 (upgrade_type): Convert tree of if's to switch. Clean up
1696 bogus "off == 0" handling with a complaint. Avoid setting
1697 field bitpos and bitsize of array with lower and upper bounds.
1698 Check specified bitsize of elements against their actual type's
1699 bitsize, and complain if different. Complain about unknown
1701 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
1702 (psymtab_to_symtab_1): Print names of subsidiary files that
1703 are being read in. FIXME, we read far too many files. This code
1704 is not the problem, the problem is in parse_fdr where the psymtabs
1706 (cross_ref): Result should indicate that we used one aux entry
1707 normally, or two if we encountered a "next" entry. This used
1708 to leave the caller pointing at the wrong aux entry.
1709 (add_symbol): If overflowed cur_block, reallocate it larger,
1710 chase all pointers to it, and complain(), rather than clobber memory.
1711 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
1712 (new_field): Only allocate one field initially, not two.
1713 Pull ++ out of macro argument. Simplify.
1714 (_initialize_mipsread): Avoid initialization of importd
1715 global_psymbols and static_psymbols.
1717 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
1718 to properly set pst->symtab; avoid searching for it.
1719 (symfile_fns): Improve comments, add a FIXME.
1720 * dbxread.c: Update comments to reflect symfile protocol.
1721 (read_ofile_symtab, end_symtab): Return the symtab.
1722 (psymtab_to_symtab_1): Set pst->symtab.
1724 * coffread.c (coff_symfile_read): tell condense_misc_bunches
1725 whether we're mainline.
1727 * symfile.h (sym_fns): Remove unused sym_discard member.
1728 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
1730 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
1731 the environment variable is not.
1732 * infcmd.c (finish_command): Use filtered printfs.
1733 * cplus-dem.c: Add struct tags to a few unnamed structs.
1734 * valops.c (value_coerce_array): Improve comments.
1735 * valprint.c (type_print_varspec_suffix): Print array size only
1736 if greater than zero.
1737 * m88k-tdep.c: Shift some lines left by one space, that had
1738 apparently been trashed at some point.
1739 * TODO: More things to do, a few got done.
1741 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1743 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
1744 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
1746 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
1747 * expread.y, findvar.c, symmisc.c: Ditto.
1748 * printcmd.c (address_info): Update printed forms of LOC_
1749 symbols. Elim LOC_EXTERNAL.
1750 (print_frame_args): Keep track of param stack offsets before
1751 re-looking up to find the local register param is kept in.
1753 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
1754 Further integration of mipsread into gdb. Eliminate unused
1755 routines, duplicate declarations. Handle static symbols in
1756 psymtabs as well as external symbols. When reading symtabs,
1757 insert symbols into the correct block (global, static, or a local
1759 (read_mips_symtab, parse_partial_symbols): Don't pass useless
1761 (mipscoff_symfile_read): Don't call select_source_symtab.
1762 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
1763 rather than SYMBOL_VALUE.
1764 (parse_external): Comment clobbering of top_stack.
1765 (parse_partial_symbols): Update comments. Allocate and parse
1766 static symbols as well as external symbols. FIXME, enum values
1767 are not handled in this pass, but should be. Inline new_psymbol.
1768 Use SYMBOL_VALUE_ADDRESS.
1769 (psymtab_to_symtab_1): Read symbols into global static block
1770 by default (until enter some function's local block context).
1771 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
1772 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
1774 * source.c (select_source_symtab): Select a source symtab
1775 from either the symtabs or, failing that, the psymtabs.
1776 (list_command): Update error message.
1777 (forward_search_command, reverse_search_command): Use getc, not
1778 fgetc, for speed. FIXME, add comment about buffers that die if
1779 overrun by long line.
1781 * values.c (unpack_field_as_long, modify_field): Avoid shifting
1782 by an entire word, which is not portable, if we have a 32-bit
1783 field. (Code in dbxread.c already turns such bitfields, if
1784 aligned, into ordinary ints, but fixing this will help for other
1785 symbol formats and for future changes.)
1786 * core.c (core_open): Handle ANSI const brain death.
1787 * utils.c (vprintf): Fix varargs typo.
1789 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1791 * findvar.c (find_var_value): Handle &function better.
1792 * TODO: Document work needed on &fn and &array.
1793 * printcmd.c (print_address_symbolic): New arg is the prefix
1794 to print if a name is printed.
1795 (print_address_demangle): Honor "set print address" now.
1796 Use new arg above to improve spacing of output.
1797 * valprint.c (val_print): When printing function pointers,
1798 print symbolic form too.
1799 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
1801 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1803 * core.c (memory_error): Reword error msg to mislead less.
1805 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
1807 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
1808 parse_partial_symbols): Use newer BFD internals (external_filehdr
1809 and external_aouthdr), byte-swap the fields that we care about
1810 before using them, and make the file header data local to
1811 read_the_mips_symtab rather than global.
1813 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
1815 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
1816 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
1818 * main.c (command_line_input): Flush stdout and stderr
1819 before every call to readline. This reportedly fixes a bug
1820 that comes up in Sys V running emacs-gdb and/or xxgdb,
1821 when stdin/out are pipes or sockets.
1823 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1825 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
1826 Avoid declaring Makefile dependencies, because GNU Make stupidly
1827 tries to update it if we do.
1829 * coffread.c: Revise for minor changes to bfd internal coff
1832 * configure: If -template= is given a relative path, make it
1833 absolute before recurring in subdirectories.
1835 * configure, configure.in, Makefile.in: Install "configure" script
1836 as replacement for config.gdb.
1837 * config.gdb, Makefile.dist, Makefile.sdir: Remove
1838 * README: Update for configure, mostly. FIXME.
1840 * Add dec3100 as equivalent to littlemips. Indicate in all host &
1841 target config files that they are for the host. When the lines
1842 get copied into the Makefile, this makes it more obvious what's
1845 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1847 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
1848 tabs, which end up in the disassembler output inadvertently.
1850 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1852 Make it compile cleanly in an ANSI GCC2 environment.
1854 * blockframe.c: <stdio.h>
1855 * cplus-dem.c: free takes a void *, ifdef __STDC__
1856 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
1858 * defs.h (alloca): Avoid doing anything if alloca already def'd.
1859 * stddef.h, stdlib.h: Remove these files.
1860 * symtab.c: Avoid declaring qsort, close.
1861 * symfile.c: Avoid declaring close.
1862 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
1863 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
1865 Assorted other changes.
1866 * dbxread.c: include "libaout.h", not "liba.out.h".
1867 * printcmd.c (print_frame_args): Set recurse properly for
1868 indentation of struct and array parameters.
1869 * valops.c (value_cast): Allow cast to void.
1870 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
1871 single_step() in a target-independent fashion.
1872 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
1873 set up to be ready to continue. This makes us target independent.
1874 * infptrace.c (child_resume): Remove call to single_step; now
1875 can single step a SPARC target of any kind.
1877 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1879 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
1880 docn into separate sections---basically chapters, plus two loose
1881 pieces that can be configured to go in different places. This
1882 allows GNU m4 to preprocess the manual without coredumping.
1884 * Makefile.dist: tell TeX where to find texinfo.
1886 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1888 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
1889 the new target "rdl-apps.texinfo" which captures the Makefile
1890 variable that records where to find the Readline libraries.
1892 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
1894 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
1895 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
1896 * defs.h (const, volatile): Only define if not already defined.
1897 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
1899 * README: Update for release 3.95.
1900 * config.gdb: Don't create readline dir in subdir builds.
1901 * main.c: Include with "..." form for non-system include files,
1902 so "gcc -MM" for "make depend" works.
1903 Include readline files with "...h" rather than <readline/...h>.
1904 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
1906 * coffread.c: Undo minor damage done by Rich Pixley. Use
1907 different internal and external representations of COFF
1908 data structures. Use new BFD routines for swapping them in and
1910 * symfile.c (free_named_symtabs): Avoid freeing file names that
1911 are null or empty. Old i960 tools seem to produce files that
1912 claim to have empty names, causing each successive file read
1913 to blow away the previous one.
1914 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
1915 Move deferred_stores to top of file, but don't separate its
1916 #define's from its variable. Add commentary.
1917 * Makefile.dist: Fix Rich damage; undo "configure" changes in
1918 favor of keeping the (working) config.gdb. Move readline
1921 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
1923 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
1925 * infptrace.c (fetch_registers): no result, since now void.
1926 * tconfig/news: target depends on m68k-tdep too.
1928 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1930 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
1933 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
1934 applied various small fixes due to or inspired by RMS comments
1936 * doc/gdb.texinfo: finished using all RMS comments, save those for
1937 appendices on readline and cmd history (which are in other source
1940 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1942 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
1943 chapter 9; (2) documented 'break' command's menu mode for
1944 overloaded names, in response to hgs problem report C++ p-31
1946 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1948 * doc/gdb.texinfo: (1) better introductory example; (2) more
1949 consistent use of @code, @samp, @file, @kbd throughout; small
1950 cleanups to first three nodes; (3) new "Contributors" node;
1951 (4) Appendix, Renamed Commands; (5) divert specialized startup
1952 instructions to "Targets" chapter for generic manuals, while
1953 leaving them up front for manuals specific to specialized
1954 environments; (6) apply fixes from RMS comments through chapter 4.
1956 * pretex.m4: modify explanatory text slightly (and redefine
1957 "regexp") to keep GNU m4 from complaining. (It still crashes
1958 later, but one step at a time...)
1960 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
1962 * readline/readline.c (update_line): Avoid dereferencing a pointer
1963 before comparing it to its bounds. Saber caught this.
1964 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
1965 and only set PC if tgetstr returned non-null. Saber caught this.
1967 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1969 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
1970 stuff for config manual) here where it counts; updated
1971 to use new subdir structure (gdb/doc/).
1973 * Makefile: generated from above via
1977 * gdbint.texinfo: added instructions on generating gdb.info* files
1978 locally for release. These are ordinary info
1979 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
1980 Makefile)---but due to use of texinfo 2, can't count on makeinfo
1981 to generate these, so we distribute them already formatted.
1983 * gdb.texinfo: included full Info node and menu crud (as generated
1984 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).

2464 tm-sun3.h: Define TARGET_SUN3.
2466 * utils.c: Use CPLUS_MARKER not '$'.
2468 * cplus-dem.c: Use CPLUS_MARKER not '$'. If CPLUS_MARKER isn't
2469 defined, define it to '$'.
2471 * arm-opcode.h: New file (same contents as before; it had
2472 just been left out of the distribution for a long time).
2474 * tm-68k.h: Put declaration of ext_format_68881 outside the macros.
2476 * main.c: New HAVE_SIGSETMASK #ifdefs.
2478 * coffread.c (read_coff_symtab): Check for "LF%" with all the
2481 * coffread.c (SDB_TYPE): New macro.
2482 various: Use it instead of checking against T_NULL.

2493 * i386-pinsn.c (OP_E): Change %d to 0x%x for consistency.
2495 * putenv.c: New file
2496 Makefile.dist: Add it to $(OBS).
2498 * mipsread.c [!CMUCS]: #include <syms.h>.
2500 * mips-xdep.c (fetch_core_registers): #if 0 out the whole function.
2502 * Move read_memory_nobpt from mem-break.c to breakpoint.c.

2542 * inftarg.c (child_open), remote-vx{,.68}.c (vx_proc_open):
2543 New function to give correct error message.
2545 Thu Apr 11 17:19:41 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
2547 * target.h: Add to_doc and target_preopen.
2548 target.c: Add target_preopen and target_command.
2550 (add_target): Call add_cmd and mess with targetlist->doc.
2551 core.c, exec.c, remote-eb.c, remote-nindy.c, remote-vx.c,
2552 remote-vx.68.c, inftarg.c, remote.c: Add doc field to target struct.
2553 Call target_preopen from open routine.
2555 * main.c: Rename editing_info to show_commands.
2556 (_initialize_main): Rename "info editing" to "show commands".
2558 * source.c: Rename directories_info to show_directories.

2570 Rename add-syms to add-symbol-file.
2572 Thu Apr 18 18:08:30 1991 John Gilmore (gnu at cygint.cygnus.com)
2574 * symfile.h (free_named_symtabs): Rename from free_named_symtab.
2575 * symfile.c (clear_symtab_users_once, cashier_psymtab,
2576 free_named_symtabs): Move these routines from symmisc.c.
2577 * symmisc.c (same): same.
2578 (free_symtab): Make non-static.
2579 * symtab.h (free_symtab): Declare as exported void fn now.
2580 * dbxread.c (end_symtab, end_psymtab): Change comments.
2581 (initialize_dbxread): Call dbx_new_init() in case the first
2582 command is add-symbols.
2583 * target.c (dummy_target): Permit add_syms_addr_command.
2585 Sat Apr 13 14:46:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2587 Permit symbols to be superseded when new symbol files have
2588 been read in, particularly for VxWorks.
2590 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
2591 to the main file, as well as to include files. Also, put global
2592 functions into the global psymtab, to make "i fun" work.
2593 (end_psymtab): Free named symtabs and psymtabs for a file, once a
2594 new psymtab for it has been read.
2595 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
2596 a file, once a new symtab has been read for it.
2597 * mipsread.c: FIXME. We need to do the same for MIPS, but it
2598 looks harder to determine the top-level block before it's been
2599 queued to the psymtab list.
2601 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
2602 If we have wiped out any old symbol tables, clean up at end of
2604 (symbol_file_command): Don't reference symfile_fns if it's zero.
2606 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
2607 defines for the blocks of a blockvector that contain global and
2608 file-static symbols and the first of the smaller scope contours.
2609 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
2610 decode_line_1, make_symbol_completion_list): Use the above.
2611 * coffread.c (end_symtab, patch_opaque_types): Ditto.
2612 * dbxread.c (end_symtab): Ditto.
2613 * expread.y (block): Ditto.
2614 * mipsread.c (throughout): Ditto.
2615 * symmisc.c (free_named_symtabs): Ditto.
2617 * symtab.c (list_symbols): Process the first symbol of the
2618 static psymbols list.
2619 (types_info): Restore this function from its untimely #if 0.
2620 It's not perfect, but it is better than nothing.
2621 (_initialize_symtab): Restore "info types".
2623 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2625 * m68k-stub.c: Remote stub for 680x0's, created from
2626 rem-m68k.shar (which is removed).
2627 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
2628 Remove RCS log stuff now that we use CVS and it blows our diffs.
2630 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2632 * symmisc.c (free_named_symtab): Make it work, in its current
2633 kludgy fashion. Change result to indicate if we blew away bkpts.
2634 * dbxread.c (end_symtab): Accumulate result from
2635 free_named_symtab and print warning if we blew user's state.
2636 * symfile.h: free_named_symtab now returns an int.
2638 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
2640 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
2641 is the first symbol read, even if not mainline.
2642 (dbx_psymtab_to_symtab): symfile might be zero, cope.
2643 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
2644 (set_section_command): New command ("section xxx yyy" -- should
2645 be renamed to "set section xxx yyy" FIXME) which sets the
2646 base address of a section of the exec file, overriding the
2647 virtual address that BFD reports.
2649 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2651 * exec.c: Add add_syms_addr_command to exec_ops, so you can
2652 load symbols at any address while examining an exec file.
2654 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
2656 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
2657 for printing the float info is host-dependent, not
2658 target-dependent. FIXME.
2659 * i386-pinsn.c: Move #includes to top, remove useless ones.
2660 * i386-tdep.c: Don't bother including <.../reg.h> since we
2661 don't use it (and it doesn't exist on host systems).
2663 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
2664 Convert negative numbers properly.
2665 (ieee_test): Make numbers really random; fix format arg.
2667 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
2668 * core.c (core_detach): Unpush core_ops, which might not be on
2669 top. We used to just pop the top, which broke things. Don't
2670 need dont_repeat() any more.
2671 (core_file_command): Psst! Don't repeat it.
2672 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
2673 * expprint.c (print_subexp): Avoid switch fallthru on
2674 BINOP_ASSIGN_MODIFY, so we can print += and such.
2675 * frame.h: Fix typo.
2676 * inflow.c (kill_command): After killing inferior, print our
2677 current frame in the core file, if we have one.
2678 (generic_mourn_inferior): When inferior dies, either select
2679 the current frame (in the new target, e.g. core file), or
2680 set both the current and selected frames to NULL.
2682 Changes from Peter Schauer.
2684 * infptrace.c: Avoid <sys/ptrace.h> on USG.
2686 * Make all file names fit in 14 characters (sigh and damn!):
2687 mv hp300hpux-xdep.c hp300ux-xdep.c
2688 mv symmetry-xdep.c symm-xdep.c
2689 mv symmetry-tdep.c symm-tdep.c
2690 mv convex-opcode.h convx-opcode.h
2691 mv tm-vxworks960.h tm-vx960.h
2692 mv tm-vxworks68.h tm-vx68.h
2693 mv Makefile.srcdir Makefile.sdir
2694 mv gdb-int.texinfo gdbint.texinfo
2695 mv remote-sa.m68k.shar rem-m68k.shar
2696 mv remote-multi.shar rem-multi.shar
2697 * Makefile.dist, README, config.gdb, convex-pinsn.c,
2698 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
2699 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
2702 * command.c (user_info_1, user_info): New command for listing
2703 the user-defined commands.
2705 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
2707 * dbxread.c (really_free_pendings): Clear file_symbols
2708 and global_symbols after freeing them; otherwise, running
2709 this function twice (if it appears twice on the cleanup
2710 chain), we try to free things twice.
2712 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
2713 based on text_addr (the address of text in core), not on addr (the
2714 offset between text in the .o file and in core). This change
2715 is from Peter Schauer.
2717 * main.c: Define ALL_CLEANUPS as a cast of zero.
2718 (return_to_top_level): Use it.
2719 (main): Do all cleanups after each command run as part
2720 of the gdb startup sequence. Also do all cleanups before
2721 entering the command loop, and every time we exit the command
2722 loop and reenter. Before, the cleanups from the startup sequence
2723 were being left undone until the first error!
2724 (command_loop): Rename do_nothing cleanup to command_loop_marker
2725 so we can see it easily when examining the cleanup chain.
2726 (init_signals): Add another do_nothing for signal handling.
2727 (quit_command): Only try to kill target if it has execution.
2728 Problems in the target stack got us into a state where
2729 inferior_pid was nonzero but none of the targets had execution.
2730 In this state you couldn't exit gdb.
2732 * dbxread.c: Two changes from Peter Schauer.
2733 (echo_command): Fflush output after an echo command.
2734 (show_history): Pass all args to cmd_show_list.
2736 * utils.c (init_malloc): Call mtrace to turn on tracing
2737 if the environment variable MALLOC_TRACE is set to a file name.
2738 * mtrace.c: Add source file which provides a log of every malloc,
2739 free, and realloc to a trace file.
2740 * mtrace.awk: Add source file which analyzes the trace file.
2741 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
2742 (VERSION): Roll to 3.94.3.
2744 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
2745 (check_duplicates): Don't bother with watchpoints.
2746 (set_raw_breakpoint): Comment about danger of this routine.
2747 (watch_command): Parse and eval all args before calling
2750 * solib.c (find_solib): Avoid error in referencing memory to
2751 see if any more shared libraries have been added. This is
2752 particularly useful if the target has terminated. Bug reported
2755 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
2756 in bringing up 3.94.2 on the Sun-3.
2758 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
2759 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
2760 expression (in scope) before reenabling watchpoint.
2761 * signame.c (init_sigs): Add missing declaration of i, fix
2762 sys_siglist declaration.
2763 * source.c (list_command): Fixed range computation to use
2765 * stack.c (backtrace_command): Do not allow command if target has
2766 no stack, print informative error message.
2767 * target.c (target_command): Do not write into command line
2768 because this fails if the target command is used in a user defined
2769 command. [This change was enhanced by gnu to support any-
2770 unique-prefix matching on target names.]
2771 * valops.c (value_struct_elt): Avoid infinite loop on an
2772 erroneous attempt to print the member of function (try p main.p).
2774 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
2776 * expread.y (name_no_typename): Avoid reduce/reduce errors
2777 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
2778 Since the GDB parser really doesn't use name_no_typename in a
2779 name-only context, the parser can't tell the diff between
2780 names and numbers here. Avoid allowing a name_no_typename
2781 to be a NAME_OR_*INT to resolve the conflict.
2783 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2785 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
2787 * valprint.c (val_print_fields): bitfield printing didn't handle
2788 byte order. Indirect through a few more fns to cope.
2790 * values.c (modify_field): also cope with byte order.
2792 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2794 Cleanup for release 3.94.2:
2796 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
2797 include files. Roll version to 3.94.2.
2799 * coffread.c (init_stringtab): Read length into unsigned char
2800 array before swapping; don't assume 32-bit longs.
2802 * target.c (target_info): Don't bother with get_sym_file, just use
2803 the symfile global variable.
2804 * symtab.h, symfile.c (get_sym_file): Delete it.
2806 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
2807 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
2808 (read_type): Replace one more error() with complain().
2810 * mipsread.c (parse_partial_symbols): Replace printf with complain.
2812 * i960-tdep.c: Fix copyright attribution.
2814 * config.gdb: Quote all backquotes in doublequotes. You can
2815 quote me on that. BSD 4.4 shell found this one.
2817 * infptrace.c (throughout): The third argument to ptrace is an
2820 * infrun.c (wait_for_inferior): When program has terminated, we
2821 have to call target_terminal_ours before we pop that target off
2822 the stack (e.g. before a call to target_kill or
2823 target_mourn_inferior). This fixes problem where a program
2824 terminates, then GDB stops for (tty output) and you have to type
2825 "fg" to the shell to resume it. FIXME: This code for what to
2826 do after termination really should be in normal_stop instead.
2828 * gdbcore.h (read_memory_check): Change declaration; it changed
2831 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
2832 4.4 prereleases, this avoids a bug in their sgtty compatability
2834 * remote.c: Use terminal.h rather than hand-rolling the same.
2836 * signame.c, signame.h (psignal): Arg is unsigned, not int.
2837 * utils.c (strsave, strstr): Fix arg types.
2838 * valprint.c (val_print): lint
2840 MIPS symbol table support from Per Bothner:
2842 * symfile.c (symtab_fns): Remove initializer table that needs to
2843 be hacked for each new symbol file format supported.
2844 (add_symtab_fns): New function, chains symbol table
2845 handlers into the global list.
2846 (symfile_init): Search this list.
2847 * symfile.h: Add next pointer, declare add_symtab_fns.
2848 * coffread.c (_initialize_coffread): Call add_symtab_fns.
2849 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
2851 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
2852 symbol *). Thus, we no longer need the hack to trash
2853 pst->filename. Good, since that hack confused code in symfile.c!
2855 (reorder_symtabs, destroy_all_symtabs): Removed static
2856 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
2857 Instead, the latter now uses a temporary array (stack-allocated
2858 from an obstack, and then freed).
2860 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
2861 haven't been set in the outermost stBlock of a procedure. This was
2862 a problem with f77 binaries on Ultrix 4.?.
2864 (new_symtab, new_symbol, new_type): Continue changing code to use
2865 obstacks more and otherwise conform to dbxread internal style.
2866 Made the free_code of symtabs be free_linetable (as in dbxread)
2867 instead of free_contents. This implies memory leaks when reading
2868 a new symbol table, until the conversion is finished. Did change
2869 (struct symbol) and (struct type) to be allocated on the
2870 symbol_obstack. Blocks and blockvectors are among the things
2873 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
2874 tested much, but it solved one problem (reported by Meissner), and
2875 cleans up some other things. The problem happened when an
2876 included file contains actual code (functions) and not just
2877 definitions. The mips coff is a little inconvenient there, since
2878 it may cause a procedure to be mapped to the wrong psymtab.
2880 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
2881 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
2882 this will need work for the new core paradigm.
2884 Opcode patches from the net:
2886 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
2887 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
2888 missing altogether - they are added here. From Bruce Bauman.
2889 * mips-opcode.h: The low mask for C0 instructions was too small.
2890 From Garrett Lau. I modified the fix to check the entire 32-bit
2893 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
2896 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2898 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
2900 * dbxread.c (read_type): Pointer subtraction (value_sub in
2901 valarith.c) sometimes failed because the types of the
2902 pointers being subtracted were not identical.
2903 These differed because dbxread.c was allocating pointer types
2904 using dbx_alloc_type+smash_to_pointer_type instead of
2905 lookup_pointer_type. I failed to find a justification for the
2906 former, so I changed it to use the latter. Similarly, I
2907 replaced smash_to_function_type by lookup_function_type,
2908 and smash_to_reference_type by lookup_reference_type.
2910 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
2911 _initialize_mipsread): corresponding changes.
2913 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
2915 * source.c (mod_path): Do tilde_expand on each component of the path,
2916 rather than on the (list of) paths as a whole.
2917 (print_source_lines): Set first_line_listed in addition to
2918 current_source_symtab and current_source_line. If the source was
2919 not findable, after a "dir" command to fix the problem,
2920 a "list" would get the wrong lines.
2922 While I was there... (gnu):
2924 * dbxread.c (read_type): Change error to complaint.
2926 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2928 First attempt at detailed understanding of symbol table memory alloc.

2934 (): FIXME: Should realloc-down the psymbol lists when done reading
2935 the main symbol file?
2937 * symmisc.c (free_symtab): Free fullname field too.
2939 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
2940 (REGISTER_ADDR): Make result type unsigned int.
2942 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
2943 define REGEX must also define REGEX1 (its dependency).

2980 in raw hex as well as float format, regardless of whether it is
2981 a "virtual" convertible register.
2982 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
2983 regs as a double, just in case it's being used that way.
2984 * values.c (unpack_long): Comment on array/function coercion.
2985 (unpack_double): Argument is in target byte order now. For
2986 integer arguments, just call unpack_long and float the result.
2987 * m68k-tdep.c: include defs.h for "const" handling.
2988 * remote-nindy.c: Use ieee-float stuff.
2989 (nindy_fetch_registers): Unpack double regs to host double, then

3003 Changes from a bringup on the DEC Vax under Ultrix 4.0.
3005 * coredep.c (fetch_core_registers): Pass end-address of register
3006 section to register_addr as expected. Don't call supply_register
3007 if we'd just pass it garbage.

3056 * inftarg.c (child_detach): Pop the child_ops vector if the
3057 detach is successful.
3058 * remote-nindy.c (nindy_create_inferior): Don't push a new
3059 nindy_ops since nindy uses the same one for execution and memory
3061 * core.c (core_ops): Use child_attach and child_create_inferior
3062 rather than default attach and create_inferior functions.
3064 Handle floating point registers in core files.
3066 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
3067 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
3068 This version untested since BFD doesn't yet support sun3 core
3070 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
3071 conventions. Fix comments and style. This version has not
3072 been compiled yet, since we have no HP inhouse.
3073 * core.c (get_core_registers): Look for two sections, ".reg"
3074 and ".reg2", and pass both to fetch_core_registers sequentially.
3076 Revise directory path yet again.
3078 * source.c (forget_cached_source_info): Not static any more.
3079 (init_source_path): New default source path is "$cdir:$cwd".
3080 (dir_command): Handle variable arguments ($cdir, $cwd).
3081 (source_info): Print "Compilation directory" rather than
3082 "Originally compiled in" to remind people of $cdir.
3083 (openp): If the path contains $cwd, use current directory.
3084 (open_source_file): If compilation directory is known, replace
3085 first $cdir in path with the compilation directory.
3086 (print_source_lines): Even if we can't print the lines, set the
3087 current symtab and line for future commands like "info source" or
3088 "breakpoint". Also, error message now contains the file name,
3089 line number, and file access error message.
3090 (_initialize_source): Fix help text to describe changes.
3091 * main.c (cd_command): Forget cached source info when we chdir.

3097 Byte-swap COFF symbol tables if necessary when reading them in.
3098 Use complain() to replace error message in one spot. Needs
3099 corresponding change in bfd/coff-code.h to make some symbol
3100 swapping routines non-static.

3114 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
3116 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
3117 <rpc/rpc.h> and <rpc/types.h>.
3119 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
3121 * i960-tdep.c (examine_prologue): Add new argument limit,
3122 which stops the scan at the end of the prologue, or at the PC.
3123 This fixes a problem where it walks down into the code for the
3124 user's statements if that code looks like function prologues.
3125 Mark Fox and I have been bouncing this code back and forth, making
3126 small changes to it. Callers changed to match.
3128 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
3130 Cleanup for gdb-3.94 release final:
3132 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
3133 the .c files from vx-share and nindy-share, from the various
3134 macros, since they are not found via ALLDEPFILES.
3135 (SFILES): Add tm-i960.h.
3136 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
3137 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files

3144 * am29k-tdep.c: Add contribution line.
3145 (examine_prologue): Cache information about function prologues in
3146 the misc-function-vector to avoid lots of references over the
3147 serial line while examining instructions.
3149 * core.c (core_close): New function made from cleanup_core.
3151 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
3152 remote-vx.c, remote.c, target.c, target.h,
3153 Update target_ops vector to add attach, close, and load entries.
3154 Use add_syms_addr_command, not add_file_addr_command, for
3155 add_file. Break out close routine from existing code.
3157 * dbxread.c (really_free_pendings): Don't free pending_blocks;
3158 they are in an obstack.
3159 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
3161 (define_symbol): Add symbol type parameter; change callers;
3162 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
3163 it to influence the symbol class on the i960.
3164 (define_symbol): Swap LOC_CONST's into target byte order.
3166 * exec.c (exec_close): New function.
3167 (exec_file_command): Call it.
3169 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
3170 Fix byte order of frame pointer.
3171 (read_var_value): Result of 0 if var's value can't be found,
3172 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
3173 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
3174 (locate_var_value): Use read_var_value and use its lazy address
3175 as the location of the var's value. Lint.
3177 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
3180 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
3181 obsolete Intel versions in favor of vxgdb versions.
3182 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
3183 code dealing with byte order of values, which Intel did in host byte
3184 order rather than gdb-4's target byte order.
3185 (i960_frame_chain_valid): Move to nindy-tdep.c.
3186 (examine_prologue, skip_prologue, frame_find_saved_regs,
3187 frame_args_address, leafproc_return, saved_pc_after_call,
3188 pop_frame): Add vxgdb versions from Mark Fox.
3189 (examine_prologue, frame_struct_result_address): Add code
3190 to deal with the saved value of G13 (struct return address
3192 (frame_args_address): Modify Mark's version to prefer the
3193 saved value over the current value in the topmost frame.
3194 Cache result in the frame info to avoid performance hair in
3196 (print_fault): Add gdb960 code for printing faults.
3197 (_initialize_i960): Actually call check_host.
3199 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
3200 add stub routines. FIXME, these currently just return zero!

3203 (attach_command): Call target_attach, not target_open, now.
3205 * infrun.c (normal_stop): Make global, not static, for vx_attach.
3206 (child_attach): Rename from child_open.
3207 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
3208 don't confuse it with a zero step_resume_break_address.
3210 * inftarg.c (child_detach): Eliminate inferior_pid test.
3211 (child_files_info): Clean up message a bit.
3212 (child_ops): Use child_attach, not child_open, to attach.
3214 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
3215 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
3216 findvar.c to here, since it depends on the contents of the
3217 shadow_contents of breakpoints, but keep if #if 0 since it is
3220 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
3223 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
3224 (ptype_command, display_command): Eliminate have_inferior_p and
3225 have_core_file_p in favor of target_has_stack or
3226 target_has_execution.
3227 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
3228 code for actually finding the values of arguments, though we still
3229 keep track of the maximum stack offset for use in printing unnamed
3230 arguments. Handle missing FRAME_ARGS_ADDRESS.
3232 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
3233 (struct nindy_regs): Define registers passed to/from nindy.
3234 (nindy_fetch_registers, nindy_store-registers): Translate between
3235 nindy and GDB formats for the registers.
3236 (dcache_init): Statically allocate the cache, since it was being
3237 allocated by a malloc that was never freed anyway.
3238 (nindy_create_inferior): Error, not core dump, if no exec file.
3239 (nindy_before_main_loop): Use target_load, not target_add_file.
3241 * remote-vx.c (net_load): Specify large timeout for load
3242 requests. Allow user to break out with INTERRUPT.
3243 (net_break): Remove useless code, clean up. Change callers.
3244 (parse-args, skip_white_space, find_white_space): Clean up arg
3245 parsing to cope with quoted strings.
3246 (net_wait, net_quit): Never call error, just return status.
3247 (vx_read_register, vx_write_register): Cleanup status checking.
3248 #ifdef the code based on which CPU we are using (960 or 68k),
3249 FIXME, this should be completely general but it isn't yet.
3250 (vx_xfer_memory, vx_resume): Cleanup status checking.
3251 (vx_run_files_info): Improve message.
3252 (vx_load_command): Renamed from vx_add_file_command. Allow load
3254 (net_ptrace): Remove unused routine.
3255 (vx_wait): Adopt code from vxgdb960 to cope with broken
3256 connections to target machine and prompt to disconnect. Remove
3257 debug printouts. Map some EVENT_'s to SIGnals.
3258 (add_symbol_stub, vx_open): Print names of object files we found,
3259 and "ok" if we read their symbols OK. Clarify output in general.
3260 (vx_attach, vx_detach, vx_kill): Add these commands.
3261 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
3262 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
3263 "info files" output, and create_inferior, since we already have
3266 * stack.c (frame_info): Replace Frame_unknown with 0.
3267 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
3268 (return_command): Pop until the PC matches as well as the FP,
3269 so it works even if the FP is shared with another function,
3270 as in "frameless" or "leaf" procedures.
3272 * symfile.c (load_command): renamed from add_file_target_command.
3273 (add_syms_addr_command): renamed from add_file_addr_command.
3274 (add_syms_command): Stub to call target_add_syms.
3275 (_initialize_symfile): Change command names and descriptions,
3276 add-file => add-syms, and load from alias to its own command.
3278 * target.c (kill_or_be_killed, maybe_kill_then_attach,
3279 maybe_kill_then_create_inferior): Default for attempts to start
3280 a process, if one is already running, is to ask about killing
3281 it and retry if yes.
3282 (upstack_create_inferior): #if-0 it, strata obsolete it.
3283 (push_target, unpush_target, pop_target): to_close() a target
3284 before unstacking it.
3285 (target_info): Renamed from target_files_info.
3286 (_initialize_targets): Rename "i files" as "i target", accessible
3289 * target.h: Improve comments about the target_ vectored routines.
3291 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.

3294 (SKIP_PROLOGUE): No longer a no-op.
3295 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
3296 (*_REGNUM): Sort register numbers.
3297 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
3298 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
3299 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
3300 are now 10 byte extendeds, not 8 byte doubles.
3301 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
3302 for nindy versus vxworks targets. FIXME, this should possibly go
3303 in the target vector.
3304 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
3305 frame_saved_regs and arg pointer with each frame.
3306 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
3307 (FRAME_ARGS_ADDRESS): Use cached result.
3308 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
3309 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
3310 (PRINT_RAMDON_SIGNAL): Call print_fault.
3311 (POP_FRAME): Now works.
3313 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
3314 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
3315 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
3316 (ADDITIONAL_OPTION_HANDLER): use target_load, not
3319 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
3320 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
3322 * valarith.c (value_subscripted_rvalue): Avoid handling
3323 floats and doubles specially; it gave alignment errors. Lint.
3325 * valops.c (value_of_variable, value_of_this): Error if unknown
3328 * valprint.c (print_floating): Bcopy rather than pointer-deref,
3329 to avoid alignment problems.

3331 (cplus_val_print): Two args are ignored; remove them. Change caller.
3332 (val_print): Use unpack_long rather than pointer-deref.
3335 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
3336 to avoid alignment problems.
3337 (value_being_returned): Error if return value unknown.
3338 (set_return_value): Add bogosity warning, FIXME. *
3340 * TODO: A woman's work is never done.
3342 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
3343 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
3344 Add ieee-float.o to OBS.
3345 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
3346 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
3347 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
3349 Changes to generalize the VxWorks RPC protocol slightly, to handle
3350 i960 as well as 68000.
3352 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
3353 * vx-share/reg.h: Produce i960 regs #ifdef I80960
3354 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
3355 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
3356 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
3357 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
3358 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
3359 so they will move in target byte order rather than network
3360 byte order (happens to be the same).
3362 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
3364 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
3366 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
3369 Add contribution lines to various files, showing where they
3372 * breakpoint.c (break_insn, check_break_insn_size,
3373 read_memory_nobpt): Remove to mem-break.c.
3375 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
3378 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
3379 entry has bad register number. This change is not
3380 tested in this release, FIXME.
3382 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
3385 * value.h: Force value's contents field to be aligned to hold
3386 at least a double or a long long (if supported). This avoids
3387 doing bcopy's in and out of the contents field.
3389 (step_1): Avoid coredump under obscure circumstances when we
3392 * symtab.h (misc_info): Add field to misc function vector for
3393 any kind of cached information the target code desires. AMD
3394 29000 uses this to avoid repeating examine_function_prologue's.
3396 * coffread.c: Lint. Remove static symfile, read_section_header.
3397 core.c (have_core_file_p): Lint: remove.
3398 expprint.c (print_subexp): Lint.
3399 infptrace.c, valops.c, valprint.c: lint.
3401 Roll in changes from vxgdb-5.0.1:
3403 * symtab.h: Comment byte order of each address class. Add
3404 LOC_LOCAL_ARG for frame-relative args (960).
3405 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
3406 symtab.c, symmisc.c: ditto.
3408 * infrun.c (init_wait_for_inferior): Clear stop_signal.
3410 * remote.c (remote_resume): Error if resume with a signal.
3412 * symfile.c (prim_record_misc_function): Clear misc_info.
3413 (fill_in_vptr_fieldno): Check stub type of arg.
3415 * valops.c (value_cast): Avoid looking up names of types whose
3416 name we don't know, to prevent coredump. Sun CC produces typedef
3417 rtx and the name of *rtx is zero...
3419 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3421 Roll in changes from final AMD 29000 port (Tiemann).
3423 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
3424 for ../include/a.out.encap.h. This might not work now that BFD
3425 is separately compiled. Instead, BFD support for encap will have
3426 to translate machine type 29k into the right COFF_MAGIC.
3428 * infcmd.c: Remove references to inferior_pid that aren't used
3429 in actual ptrace calls; use target_has_execution, etc.
3430 (have_inferior_p): Remove function.
3431 (program_info): Print target info rather than "process number";
3432 avoid gratuitous messages unless from_tty.
3433 (run_stack_dummy, finish_command): Set proceed_to_finish.
3434 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
3435 main.c: Lint. Lose have_inferior_p().
3436 inferior.h (have_inferior_p): Remove, lint.
3437 (proceed_to_finish): Add flag to ask that all regs be saved
3438 by normal_stop, for the few commands that need it, speeding up
3439 serial I/O. Add comments to stop_registers.
3441 * remote-eb.c: Remove newline from breakpoint message we grep
3442 for. Never time out when running the user program.
3446 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3448 Roll in changes from vxgdb-5.0.1:
3450 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
3451 symbol in its raw form, we are processing an unlinked ".o" file.
3452 See if the target environment has assigned it an address, using
3453 target_lookup_symbol (VxWorks does), and enter it into the symtab
3456 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
3457 68k versions for a simpler version that assumes zero FP at bottom.
3458 Fixes bug of truncated stack reports.
3460 * target.h (target_lookup_symbol): Define this routine's args
3461 and result, finally.
3463 * target.c (nosymbol): Default routine for target_lookup_symbol.
3464 (target_default): Default lookup_symbol and call_function too.
3465 (files_info): Only print has_all_memory warning if a non-dummy
3468 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
3469 vx_convert_from_virtual): If target does not have floating point,
3470 zero register "values", and avoid doing cross-net conversions.
3471 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
3472 (vx_open): Rearrange code that attaches to target and reads
3473 symbols for all loaded modules, to work if some of the modules
3474 are not accessible. Add symbol_stub() and add_symbol_stub()
3475 as callbacks from catch_errors(). Allow connect attempt to be
3476 interrupted painlessly with ^C (FIXME, there are still some bugs
3477 if the interrupt happens during symbol reading.). Print
3478 final message with puts_filtered, since symbol messages are
3483 * main.c (catch_errors): Only print errstring if non-null.
3484 (command_loop): Avoid an ioctl per command to test ISATTY.
3486 * remote-vx.c (net_load): make static; avoid sophomoric msg.
3487 (vx_xfer_memory): Return correct result!
3488 (vx_files_info): Indicate whether target has float or not.
3489 (vx_lookup_symbol): Complain, not error, if target gone.
3490 (vx_open): Print "Connected" msg before disabling immediate-quit.
3491 [FIXME: lookup_symbol and vx_open changes need testing.]
3493 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
3494 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
3495 contributor lines and update copyrights to 1991.
3497 Changes from an attempted H-PUX host port:
3499 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
3500 defines PT_ATTACH and PT_DETACH but not PT_KILL.
3501 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
3502 * remote-vx.c: include <sys/time.h> for HPUX.
3503 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
3504 "core_file_command" routine to BFD regime. May not work yet.
3506 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
3508 * xgdb.c: Replace X10 version with some VJ version.
3509 (FIXME: Its copyright assignment is not on record.)
3510 * xgdb.c: Update include files to X11R4 (Xaw crud).
3511 (xgdb_display_source, create_text_widget): fix call to
3512 get_filename_and_charpos. Rewack source window stuff for X11R4
3513 (gleaned from include files, and "nm's" of binary libraries, since
3514 I had no doc available).
3515 (append_selection, append_selection_word): Disable with FIXME
3516 since R4 changed interface here.
3517 (create_buttons): Add back the old set of buttons.
3518 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
3520 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
3521 Roll VERSION to 3.94 (not yet final though).
3523 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3525 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
3526 obstack_int_grow, obstack_int_grow_fast): Eliminate
3527 cast on left of assignment, which gives MIPS cc fits and is
3530 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
3531 F_ALIAS. Use printf, not fprintf, when not passing a file
3533 (compare_opcodes): Check that identical instructions have
3534 identical opcodes, complain otherwise.
3536 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
3537 was reported by Roland McGrath.
3538 (unimp): Only match if exactly zero instruction. (Roland)
3539 (branches and traps): Generate all variations of these
3540 instructions with macros, based on a single call that defines
3541 each condition name and its binary representation.
3542 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
3544 * valprint.c (val_print_fields): Take, and use, format parameter.
3545 This means that "p/x struct" again prints the elements in the
3546 desired format. Changed callers.
3548 * stack.c (frame_info): Use filtered output, and indicate wrap
3549 points. Remove kludgy formatting designed to avoid line wrap.
3551 * utils.c (wrap_here): If the line is already full (because
3552 we had printed a long indent or long wrapped string), do an
3553 immediate newline-and-indent.
3555 * m68k-pinsn.c (print_insn_arg): Bugfix from
3556 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
3557 instruction is incorrectly disassembled as bkpt #8.
3559 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
3560 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
3561 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
3562 and then will dump core (sometimes). I traced it back to an
3563 uninitialized symfile_name in psymtab_to_symtab.
3564 (const_vol_complaint): Add quotes to message.
3565 (define_symbol): Only believe line number if gcc_compiled.
3566 Avoid allocating symbol if we will not return it.
3568 Add target strata support so that newly established targets go
3569 into their right place in the target stack (e.g. a new exec file
3570 doesn't wipe out the ability to access the running process).
3572 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
3573 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
3574 and initialize it properly in all the targets.
3576 * target.h: Document strata. Change return type of push_target.
3578 * target.c (nomemory): new function for dummy memory access.
3579 (tcomplain): Rename complain, now also used in symfile.c.
3580 (push_target): Push targets within strata. New return value shows
3581 whether new target is on top of stack or not. Always keep dummy
3583 (target_files_info): Ignore dummy target.
3585 * core.c (core_open): Warn user, and skip accessing file, if the
3586 core target is not the topmost target in the stack.
3587 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
3590 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
3591 target_ops, it doesn't belong there since we have no regs there.
3592 Change name of target from machine => memory to clarify.
3594 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
3596 * Freeze version 3.93 for release.
3598 * Makefile.dist: Handle vx-share and nindy-share subdirs
3599 properly when building gdb.tar.Z.
3601 * symtab.c: lint; add no_symtab_msg to consolidate the messages
3602 printed in various places, so I could change just one copy.
3604 * dbxread.c, coffread.c: Change references to bfd->iostream
3605 to cast to FILE *, now that BFD avoids needing types defined
3606 in other header files.
3608 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3610 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
3611 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
3612 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
3613 (actually gcc -Wall).
3615 * dbxread.c: Remove first_global_sym, last_global_sym, since
3616 they are never referenced.
3618 * defs.h (baud_rate): Declare.
3619 main.c: Define it, and add the -b option to set it.
3621 * gdb-int.texinfo: Add text on how to define a new host or target
3622 architecture, prompted by Per Bothner's questions about MIPS
3625 * gdb.texinfo: Document "complaints". Change doc of -q since
3626 gdb no longer prints the copyright and blurb if you specify a file
3627 name to be debugged (just like Emacs). Add doc for Nindy-specific
3628 command line flags for specifying target serial port and such.
3629 Update copyright to 1991.
3631 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
3632 has taken over for us the job of ripping up executable files. The
3633 crud caused Per Bothner's port to not compile.
3635 * infrun.c (normal_stop): Avoid printing "Program exited
3636 normally" if we are in batch mode. This allows a GDB which
3637 executes a program on a target system, to behave like a Unix
3638 command (input from stdin, output to stdout, no extraneous
3641 * main.c (main): Allow additional machine-dependent command line
3642 options to be specified with the ADDITIONAL_OPTIONS,
3643 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
3644 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
3645 processing to occur just before the main loop with
3646 BEFORE_MAIN_LOOP_HOOK.
3647 (main): If a "core file" argument is specified, and it is not a
3648 core file, try it as a process ID to attach.
3649 (symbol_completion_function): Attempt to cope with
3650 "show screen-" TAB, not very successfully. This needs more work,
3652 (batch_file): New function, returns whether we are reading
3653 commands from an interactive tty on stdin, or from somewhere else.
3654 Called by normal_stop since it doesn't get from_tty passed down
3655 to it like many commands do.
3657 * remote-nindy.c: Handle command line options for nindy
3659 (nindy_before_main_loop): Prompt user for tty name if they
3660 don't specify it before getting to the interactive command loop.
3662 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
3663 and -r command line options. Also add hook before main loop
3664 to make it easy to specify a tty.
3666 * TODO: More things to do, one done.
3668 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
3670 * dbxread.c: Make complaint() calls pass pointer, not struct.
3671 Add complaints about badly formatted C++ type information
3672 (const/volatile indicator, and parse errors resulting in
3673 error_type). Fix C++ virtual member fn comment.
3674 (read_struct_type): Avoid bumping pointer if we got a parse
3675 error; this prevents our walking beyond the end of a string.
3676 Terminate loop on null char as well as semicolon.
3677 (process_one_symbol): Fix the LBRAC fix so that it uses the
3678 last previous SLINE, FUN, or SO record's PC address. C++ debug
3679 symbols did not have SLINE records in a useful order compared
3680 to the LBRAC records.
3681 (define_symbol): Handle "catch" records.
3683 * symtab.c (check_stub_type): Added new complain
3684 `stub_noname_complain' and added a consistency check to
3685 keep the debugger from crashing when finishing from an
3686 exception frame. A real fix will be needed later.
3688 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
3690 * infcmd.c (attach_command): Make global.
3692 * Makefile.dist (REMOTE_OBS): Make these compile by default,
3693 but make them easy to comment out. Perhaps later they should
3694 be enabled by what CPU you configure for? FIXME.
3695 (VERSION): Roll to 3.93.
3696 (pinsn.o): Remove rule for obsolete file.
3697 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
3699 Run down a problem that manifested by printing the wrong function
3700 name in stack traces of read_ofile_symtab. Turned out that the
3701 problem was the SunOS 4.1.1 (and previous) C compiler outputs
3702 the LBRAC symbol with an address in the *data* segment, which
3703 blew our binary search through the blocks.
3705 * dbxread.c: Use the complain() facility consistently to bitch
3706 about problems in the symbol file we are reading.
3707 (finish_block): Add code to check the nesting of the blocks;
3708 complain and Procrust them to fit if wrong.
3709 (make_blockvector): Check the order of the blocks, complain
3710 [but don't cope] if wrong.
3711 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
3712 symbols to be sure their PC value is greater than the last SLINE
3713 (line number) symbol we've seen, complaining and adopting the
3714 SLINE PC value if wrong.
3716 * symfile.h (struct complaint, complaint_root, complain,
3717 clear_complaints): Add.
3718 * symfile.c (complain, complaint_root, clear_complaints): Add
3719 facility to deal with non-fatal complaints and to regularize their
3721 (symbol_file_add): Clear complaint counters to allow new complaints.
3722 (initialize_symfile): Add 'set complaints' and 'show complaints'.
3724 * dbxread.c (dbx_symfile_read): Remember the address and size
3725 of the string table for the main symbol file, so we won't read it
3727 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
3728 to avoid reading the string table yet again. Lint.
3729 (throughout): Improve filtered output, including word wrap.
3730 (read_range_type): Improve Bothner's fix to handle other types too.
3732 * utils.c: Improve line wrap implementation. Handle unlimited
3733 width by making chars_per_line unsigned.
3734 (puts_filtered): New, easy, function.
3736 * defs.h (puts_filtered): add.
3738 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
3739 call the identical sort_symtab_syms() in symfile.c instead.
3741 * expread.y: Suggest the `file' command rather than `symbol-file'.
3743 * command.h (enum var_types): Add zinteger for seroable
3745 * command.c (do_setshow_command): Handle var_zinteger. Restructure
3746 nested if's into a switch.
3748 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
3749 we did not stop because of a breakpoint (it must have been for
3750 some other reason, like a "stepi"), so don't print anything.
3752 * symtab.c: Include <sys/types.h> all the time. Now that BFD
3753 doesn't include <sys/types.h>, old SunOS's require it for
3756 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
3758 A test port of gdb-3.92.6 to the Sony NEWS.
3761 Don't normally link in remote- or vx stuff.
3762 Some of it doesn't compile, and it wastes space for 99% of the users.
3763 Remove reference to no-longer-used HAVE_VPRINTF.
3764 Fixed BFD_DEP typo to BFD_DIR.
3766 Fix cast in arg to bfd_h_getlong.
3767 Make char *prefix be const.
3768 Fix how certain range types are mapped into builtin unsigned int types.
3770 Remove 2 #includes. They cause errors (on Sony, at least),
3771 and aren't needed (they wern't in earlier versions).
3773 print_address_symbolic should never demangle labels
3774 (since it prints *assembler-level* labels).
3776 [This was superseded by the change to printcmd below.]
3779 Add some "volatile" return types to avoid warnings.
3780 If MISSING_VPRINTF add vprintf function and not just macro
3781 (since vprintf is used in printcmd.c).
3783 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
3784 (The latter isn't grokked by some PCC-based compilers.)
3786 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
3788 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
3789 * nindy-share/coffstrip.c
3790 Added some forward declarations (otherwise, gcc complains
3791 about implicit extern redefined as static).
3793 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
3795 Changes inspired by Per Bothner:
3796 * printcmd.c (print_address_symbolic): Take additional parameter
3797 specifying whether to demangle.
3798 (print_address): Pass in asm_demangle to control demangling.
3799 (print_address_demangle): New fn, takes explicit arg to control
3801 * utils.c: Add new vars demangle and asm_demangle, and let them
3803 (fputs_demangled): If !demangle, just print the argument.
3804 (fprint_symbol): If !demangle, just print raw symbol.
3805 * valprint.c (val_print): Call print_address_demangle rather than
3806 print_address, to cause demangling to depend on the global
3807 rather than assembler-level demangling setting.
3808 * WHATS.NEW, gdb.texinfo: Document.
3810 * main.c (show_command): Show all settings if no arg.
3811 (initialize_main): Make "info set" the same as naked "show".
3812 * command.c (cmd_show_list): Handle prefix commands in the
3813 list, and print the name of the setting as well as its English
3814 description and value.
3816 Allow gdb functions to specify where a line should wrap if it
3817 exceeds the size of a terminal line. Use it to make the output
3819 * utils.c (set_screen_width_command): New fn, mallocs a buffer
3820 of the right size when screen width changes.
3821 (set_screensize_command, screensize_info): Remove #if 0'd fns.
3822 (wrap_here): New fn, indicates a point in the output where we
3823 should wrap the line rather than just letting it overflow at a
3825 (fputs_filtered): Implement wrapping.
3826 (n_spaces): New fn, returns a pointer to N spaces.
3827 (print_spaces_filtered): Use n_spaces.
3828 * defs.h (n_spaces): Declare.
3829 * stack.c (print_frame_info): Wrap with 4-space indent after
3830 fn name and before filename and line number.
3831 * printcmd.c (print_frame_args): Wrap with 4-space indent
3832 before each argument name is printed.
3833 * valprint.c (value_print): Wrap with no indentation before
3835 (val_print_fields): Wrap with indentation relative to nesting
3836 level before each field name.
3837 (val_print): Wrap with nesting indentation before array elements.
3838 * command.c (do_setshow_command): Avoid extra newlines,
3839 wrap with 4-space indent around values printed, end with period.
3840 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
3842 * breakpoint.c (breakpoint_1): Implement addressprint for
3843 "info breakpoints" display. Change file name and line number
3844 format to " at file:nnn" rather than " (file line nnn)".
3845 * gdb.texinfo: Document.
3848 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3850 Frozen for gdb-3.92.6 release.
3852 README, WHATS.NEW: Update for 3.92.6 release.
3854 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
3855 coffread.o from configs since it is now built by default.
3856 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
3857 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
3858 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
3859 from configs since it is now built by default.
3861 Makefile.dist: Update for release 3.92.6. Handle files that
3862 have been moved to ../include, ../getopt, or ../bfd. Add
3863 saber.suppress and tests directory. Add config.status to
3864 the release (it will say "none").
3866 coredep.c: Minor formatting fixes.
3868 These changes were made in early December but only checked in now:
3869 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
3870 nindy-share/nindy.c: lint
3871 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
3872 register values coming back from the target; we store values
3873 in target byte order everywhere.
3875 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
3877 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
3879 * valprint.c (cplus_val_print, val_print_fields): New functions,
3880 which print C++ objects. They conspire to avoid printing a
3881 virtual base class more than once, following all the twists and
3882 turns of C++ virtual base rules.
3883 (val_print): Call the above rather than do it by hand.
3885 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
3886 symbol file, not for added files like shared libs. This really
3887 needs to be generalized to a timestamp per file.
3889 * core.c (cleanup_core): Avoid coredump if no core file.
3891 * config.gdb: Accept -host or -target in place of +host or
3894 * coffread.c (find_linenos): Avoid desupported BFD interface
3895 to line numbers. We still read them manually rather than using
3896 BFD's "generic" features.
3898 * gdbrc.tex, threecol.tex: Add GDB reference card and its
3900 Makefile.dist: Add refcard to OTHERS list for creating tar files.
3902 * Makefile.dist: Eliminate use of $< in explicit targets.
3904 * readline/Makefile: Use $< rather than $*.c, which does not
3905 include the VPATH in GNU Make.
3907 * tconfig/i960-bout, tconfig/i960-coff: These are identical
3908 copies of tconfig/i960, added for global configuration
3909 compatability. All i960 versions can read both coff and b.out.
3911 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
3912 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
3915 * TODO: Think of more things to do.
3917 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
3919 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
3920 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
3921 64-bit float conversion.
3923 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
3924 equivalent to sun?os4 so global config works.
3926 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
3928 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
3930 * main.c: Only declare linesize once; declare pagesize not at
3931 all, since it is never used.
3932 (main): Clear newly allocated line before it is used.
3934 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
3936 Further stabilization for the Intel 960.
3938 * Makefile.dist: Parameterize the location of the "include"
3939 and "bfd" directories, as well as "getopt". Add symfile.c.
3940 Link in both dbxread and coffread. Fix up "make depend" to
3941 rewack the locations of include, bfd, and getopt in its output.
3943 * README: Document moving include files, improve some of
3946 * coffread.c: Move common code out to symfile.c. Change
3947 symbol_file_command style interface to use new *_symfile_init
3948 and *_symfile_read interface under BFD. Use BFD internal
3949 info to locate line table, symbols, etc.
3951 * core.c (core_fetch_registers): Rename to get_core_registers
3952 to avoid confusion with fetch_core_registers.
3953 (register_addr): Move to coredep.c, which is already machine
3954 dependent. This leaves core.c pretty clean of dependencies.
3956 * coredep.c (register_addr): Accept this routine from core.c.
3958 * dbxread.c: Move common code (with coffread.c, etc) into new
3959 symfile.c. Each psymtab now contains a pointer to the
3960 format-dependent function that knows how to read it in. Make
3962 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
3963 (process_one_symbol): Add code to complain about a "compiler bug
3964 we muzzle here", if we actually see it.
3966 * eval.c (evaluate_subexp): Insert missing "break" statements
3967 in code that determines whether a variable is an lvalue in
3968 memory, register, or whatever. I detected this via a compiler
3969 bug in which it *almost* mashed out the whole switch statement.
3971 * gdb-int.texinfo: Add minor sections on configuring gdb for
3972 release, and about the README file.
3974 * infcmd.c (registers_info): Fix formatting somewhat. Still
3975 not as pretty as before, but it handles byte swapping.
3977 * remote-nindy.c: If data cache routines are interrupted while
3978 waiting for the remote end, be sure that any uninitialized cache
3979 blocks are on the free list, not on the valid list!
3981 * symfile.h: Flesh out this header file with all the various
3982 routines and variables that have been merged in from dbxread.c
3983 coffread.c, and symtab.c to symfile.c.
3985 * symfile.c: New file, containing code common to dbxread.c,
3986 coffread.c, and some code from symtab.c. All generic code for
3987 reading symbol files should be in here now.
3988 (unrecord_misc_function): Remove unused function.
3990 * symtab.h: Remove file-reading things to symfile.h.
3992 * symtab.c: Remove file-reading things to symfile.c.
3994 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
3995 to decode i960 fault types.
3997 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
3998 target.c: Change type of the "resume" function from int to void,
3999 since its result was never used.
4001 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
4003 * main.c: Replace "stupid" with "caution"; you now "set caution
4006 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
4008 * infcmd.c (do_registers_info): Call val_print to deal with the
4009 byte order of the registers being printed. FIXME, this makes
4010 the formatting of the output uglier.
4012 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
4013 defined, call it for signals the debugger doesn't itself use.
4014 The i960 uses this for more detailed fault information.
4016 * remote.c (remote_open): If arg is null, print help rather than
4019 * sparc-xdep.c (register_valid): Avoid declaring size, since
4020 various modules will think of various sizes depending on the
4021 architecture of their tm-file. FIXME, we need protection against
4022 actually entering one of those modules, which would clobber
4023 storage if not for the target architecture compiled into gdb.
4025 * stack.c (up_command, down_command): Always print the frame
4027 (up_silently_command, down_silently_command): New commands
4030 * i960-pinsn.c (reg), i960-tdep.c: Lint.
4032 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
4033 more parameters than it used to.
4035 * findvar.c (registers): Increase slop to 256 bytes, which should
4036 protect us against even most RISC machines with large register
4038 (locate_var_value): Move declaration inside related ifdef.
4040 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
4041 throughout, to avoid throwing away buffered input from the board.
4042 (nindy_wait): Supply_register takes addr_of_value, not value.
4043 (i960_print_fault): Renamed from i80960_fault.
4044 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
4045 (nindy_store_registers): Avoid regs_changed stuff, just stuff
4047 (nindy_create_inferior): Don't bother to write PC_REGNUM since
4048 we can set the PC in the call to proceed(). Unpush nindy_ops
4049 before pushing it on top, to avoid message to user. Eliminate
4050 commentary from Unix machines that just misleads here.
4051 (reset_command): Fix error message to suggest target command.
4053 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
4055 Release 3.92.5 as frozen.
4057 Stabilize the merged release...with help from lint, Saber C,
4060 Everywhere: Add include files needed to declare return types
4061 of functions called.
4063 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
4065 * breakpoint.h: Add undeclared breakpoint functions, and some
4066 functions for display handling since I couldn't think of a better
4069 * breakpoint.c (insert_breakpoints): Make code for disabling
4070 shared library bkpts more likely to work. It's used when we
4071 rerun a program and stop before the shared library has been
4073 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
4074 cast from pointer, so it squeezes through catch_errors.
4075 (bpstat_stop_status): Fix logic broken some time ago. We now
4076 always create a bpstat if the stop address matches a breakpoint,
4077 even if we don't stop there -- just like the old code used to do
4078 before I got my fingers into it (sigh).
4079 (breakpoint_1): Print "ignore count" after "stop only if"
4080 condition, since that's how it actually works.
4081 (mention): Handle watchpoints as well as breakpoints.
4082 (watch_command): use set_raw_breakpoint and mention to do most
4083 of the work (and initialize all the fields!). Only pass one
4084 arg to parse_c_expression, since that's all it takes.
4086 * command.c (not_just_help_class_command): Rename arg to args
4087 since we ignore "unused argument" warnings on vars named "args".
4088 inflow.c (child_terminal_info): ditto.
4089 infptrace.c (kill_inferior): ditto
4090 main.c (catch_errors, version_info, quit_command, pwd_command,
4091 source_command, dump_me_command, editing_info,
4092 set_history_size_command, set_history, show_history,
4094 stack.c (locals_info): ditto
4095 target.c (target_files_info): ditto
4096 valprint.c (set_input_radix, set_output_radix): ditto
4098 * core.c: Remove old variables for handling core and exec file
4099 sections (data_start, data_end, stack_start, stack_end,
4100 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
4101 text_end, exec_data_start, exec_data_end, text_offset,
4102 exec_data_offset, data_offset, stack_offset). They're
4103 superseded the more general build_section_table and
4105 (get_exec_file): Mention the `file' command.
4106 (read_memory_check): Rename to memory_error, and only call it
4107 in the case of an actual error.
4108 (read_memory, write_memory): call memory_error.
4109 (core_fetch_registers): Register section name is ".reg".
4111 coredep.c: Remove a bunch of crud now that all this file does
4112 is pull the registers out of a core file.
4113 (fetch_core_registers): Rewrite to actually work, I hope.
4115 dbxread.c: Use a.out.gnu.h, not system a.out, now.
4116 Replace index() with strchr(). Remove all the pre-BFD macro
4117 definitions for accessing the symbol file.
4118 (struct dbx_symfile_info): Encapsulate the information that
4119 dbx_symfile_init needs to pass to dbx_symfile_read in this
4122 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
4123 dbx_symfile_discard): Rearrange symbol file reading to divide
4124 the format-specific part from the format-independent part,
4125 leaving the format-independent part such as file name expansion
4126 and opening in symtab.c. This replaces
4127 partial_symbol_file_open and partial_symbol_file_read.
4128 Symbol_file_read, add_file, add_file_target_command,
4129 add_file_addr_command move to symtab.c. Pass an explicit
4130 "mainline" flag for when reading the main symbol table, rather
4131 than relying on the offset address to be zero or nonzero.
4133 (dbx_symfile_read): Don't allow void *'s to be printed as
4135 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
4136 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
4137 macro" debug version really work.
4138 (read_dbx_symtab): Remove unref'd parameter inclink.
4139 Avoid swapping N_SLINE symbols, for speed.
4140 Merge N_TEXT!N_EXT case with the other external symbol
4141 definitions' case. Add comments.
4142 (start_psymtab): Allocate the symfile name in the psymtab on
4143 the psymbol_obstack, rather than using the caller's storage.
4144 (end_psymtab): Only allocate a dependencies list if there are
4146 (psymtab_to_symtab_2): Use BFD when reopening file to read
4147 its symbols for real.
4148 (read_struct_type): Add FIXME comments where it needs work
4150 (read_huge_number): Add FIXME about overflows.
4151 (read_range_type): Add FIXME about comparing a long to 1<<32.
4153 * coffread.c: Minor changes to move things closer to the new
4154 regime with symtab.c and dbxread.c Major work is still needed
4157 * exec.c (exec_file_command): Remove old variables (see core.c
4159 (xfer_memory): If memory transfer is right at the end of a
4160 section, don't lose.
4162 * findvar.c (get_saved_register): If value is in a real
4163 register, LVAL is lval_register, not lval_memory.
4165 frame.h: Declare print_sel_frame and record_selected_frame.
4167 gdb-int.texinfo: New file, for GDB internals documentation.
4168 Very simple, unformatted doc of cleanups is there for now.
4170 gdbcore.h: Remove obsolete variables that described a.out
4171 section addresses and offsets. (See core.c above.)
4172 Declare fetch_core_registers and registers_fetched.
4174 getopt.c: Declare char *alloca(); even on SPARC.
4176 infcmd.c (run_command): Call target_kill rather than
4178 (step_command, next_command, stepi_command, nexti_command):
4179 Declare from_tty parameter even though we don't use it.
4180 (run_stack_dummy): argument BUFFER is a char array, not
4181 a pointer to REGISTER_TYPE.
4182 (finish_command): using_struct_return needed a value *,
4183 not a struct symbol *.
4185 * infptrace.c (child_xfer_memory): To avoid dependency on
4186 where sections are in memory, try PT_WRITE_D and if that fails,
4187 try PT_WRITE_I. Most Unixes don't care which you use.
4189 * infrun.c (step_resume_break_shadow): Change to array to
4190 match other breakpoint shadow storage.
4191 (clear_proceed_status): Pass address of bpstat to
4192 bpstat_clear, not the bpstat itself.
4193 (child_create_inferior): FIXME comment about if the child
4195 (start_inferior): Remove old function.
4196 (child_open): Use target_kill rather than kill_inferior.
4197 (wait_for_inferior): Ditto.
4198 (insert_step_breakpoint, remote_step_breakpoint): Use
4199 new step_resume_break_shadow.
4201 * inftarg.c (child_wait): If all child processes die,
4202 pretend that the one being waited for exited with signal 42.
4204 * main.c (command_line_input): When scanning for comments,
4205 don't coredump on unclosed quotes.
4206 (quit_command): Use target_kill rther than kill_inferior.
4207 (_initialize_main): Rename class_user from "user" to
4210 * printcmd.c (print_command_1): Initialize "fmt" if no format
4211 is specified by the user.
4212 (print_frame_args): Only add to args_printed if we are
4213 actually fetching args from the stack (avoiding undefined
4215 (_initialize_printcmd): Remove bogus \{ from string.
4217 * remote-eb.c (eb_open): Avoid coredump on no argument.
4219 * remote-nindy.c: Bring out of Intel environment into new
4220 target environment. Remove all conditional compilation on
4221 I80960. Massive hacking throughout.
4222 (nindy_xfer_inferior_memory): New routine stolen from
4224 (nindy_create_inferior): New routine pieced together, probably
4225 not quite working yet.
4226 (nindy_ops): New target_ops struct for nindy.
4228 * remote-vx.c: Use write_memory rather than target_write_memory
4229 to get error checking.
4230 (vx_add_file_command, vx_open): Use symbol_file_add rather than
4232 (vx_create_inferior): Use target_terminal_ours...
4234 * signame.c (_initialize_signame): Always initialize, since
4235 we need the table for things other than psignal.
4237 * solib.c (solib_add): Use symbol_file_add, not add_file.
4238 (solib_address): Return boolean result rather than struct
4239 pointer which nobody else knows the type of.
4241 * sparc-tdep.c, valops.c: Use write_memory rather than
4242 target_write_memory, to get error checking.
4244 * stack.c (locals_info, catch_info, args_info,
4245 get_selected_block, frame_command, up_command): Use
4246 target_has_stack, rather than have_inferior_p or
4249 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
4251 * symfile.h: New file, defining the interface between the
4252 generic and object-file-specific symbol reading code.
4254 * symtab.c: Move generic symbol-reading interface to symtab.c,
4255 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
4256 table to map BFD targets to symbol-reading modules in GDB.
4257 Change index to strchr.
4258 (lookup_struct_elt_type): Use error() rather than hand-made
4259 simulations thereof.
4260 (lookup_partial_symbol): Speedup slightly when length == 0.
4261 (symbol_file_add): New function.
4262 (symbol_file_command): Call it.
4263 (symfile_open, symfile_init): New function.
4264 (add_file_target_command, add_file_addr_command): moved from
4267 * target.c (target_command): use target_kill.
4269 * target.h (target_files_info): Don't declare, never called
4272 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
4273 files to determine stack end address.
4275 * valarith.c (value_x_binop, value_x_unop): Change error message
4276 to be more useful. Pass proper argument to value_struct_elt.
4278 * valops.c (value_assign): FIXME comment that long long
4279 bitfields will break here.
4281 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
4282 Update `make saber_gdb' to work better.
4284 * TODO: A woman's work is never done.
4286 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
4287 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
4288 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
4289 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
4290 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
4291 valops.c, valprint.c, exec.c: Lint.
4294 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
4296 Continuing Intel 960 port merge of GDB.
4298 * Makefile.dist: Merge i960 "nindy-share" files. Rename
4299 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
4300 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
4301 Wack over "make depend" so it handles files in subdirectories
4302 vx-share, nindy-share, bfd, and in the current directory.
4304 * blockframe.c (get_prev_frame_info): Remove fatal error
4305 if stack not defined.
4307 * core.c (core_open, core_detach): New functions that handle
4308 the old "core-file" command as "target core" and "detach" instead.
4309 (core_file_command): Call them.
4310 (core_xfer_memory): Use common routine xfer_memory.
4312 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
4313 dbxread now uses bfd for everything but symbol reading itself.
4314 BFD internals are used to drag out the relevant file offsets.
4315 (partial_symbol_file_open): Change args all around for BFD.
4317 * symtab.c: Rename "value" to "val" everywhere, so we can
4319 (symbol_file_command): New command, moved from dbxread.c
4320 and coffread.c. It uses BFD to read the file, then vectors
4321 based on its type, to dbx or coff symbol readers.
4322 * symtab.h: Extern a few vars for symbol_file_command.
4324 * target.h: Breakpoint takes a char * save area, not a char **.
4326 * valprint.c (val_print): When unpacking bitfields, offset
4327 the address in gdb of the value, if it is declared with a shorter
4328 type. Remove the last "runtime kludge test" of host byte order.
4330 * utils.c: Remove old my_bfd_read routine.
4332 * stack.c (frame_info): Use target_has_stack. Print program counter
4333 register's actual name rather than "pc", since it's called the
4334 "ip" (instruction pointer) on the i960 (sigh).
4336 * target.c (target_command): Add command for selecting a target
4337 type and calling its open routine. This is used for initiating
4338 communication with a particular target, in a generic way.
4340 * tm-i960.h: Update for modern gdb. Remove semicolons from
4341 various macros. Handle reading struct return convention, and
4342 error-out attempts to return structs with the "return" command.
4343 Be sure gdb doesn't think we know how to call functions in the
4346 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
4347 to i960_xxx in lower case.
4348 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
4349 not being defined yet.
4351 * remote.c (remote_open): Call start_remote to initialize
4352 wait_for_inferior during open.
4353 (remote_xfer_inferior_memory): Return length written rather
4356 * remote-vx.c (target_command -> vx_open): Use new generic
4358 * remote-eb.c, inftarg.c, exec.c: ditto.
4360 * infrun.c: Fix comments.
4361 (attach_program -> child_open): Use new generic target command.
4362 (wait_for_inferior): Clear saved register values before target_wait,
4363 so target_wait can set some of them if convenient.
4365 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
4366 Return success indicator, not void.
4367 (child_xfer_memory): Avoid fetching initial word if we'll
4368 overwrite it anyway.
4370 * infcmd.c (attach_command): Use new generic target open routine.
4371 (_initialize_infcmd): Update doc on attach and detach commands.
4372 (do_registers_info): Merge in a byte-order problem as a FIXME
4375 * findvar.c (find_saved_register): Avoid problem in current frame.
4376 (read_relative_register): Ditto.
4377 (write_register): Convert byte order on the way out.
4379 * exec.c (file_command): Add.
4380 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
4381 (xfer_memory): Common function between core_xfer_memory and
4383 (exec_xfer_memory): Use it.
4385 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
4387 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
4388 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
4389 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
4391 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
4393 Merge Intel 960 port of gdb, continuing...
4395 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
4396 symbol_file_command): Pass from_tty arg to hush 'em up.
4398 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
4399 Add magic numbers for 960 COFF format.
4401 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)

4409 Remove temp file if download is interrupted.
4411 Wed Aug 1 09:08:33 PDT 1990
4412 Now uses binary protocol to talk to NINDY.
4413 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
4414 Times out after 5 seconds when trying to talk to NINDY.
4416 Tue May 29 12:54:49 PDT 1990
4417 Added variable baud rate (-b switch).
4418 Source code reorganization.
4420 Thu Apr 26 11:09:55 PDT 1990
4421 More cleanup of batch mode; specifically, execute "-s", "-e", and
4422 "-se" switches as soon as they are encountered on the invocation line.
4424 Fri Apr 20 13:47:15 PDT 1990
4427 Thu Apr 19 09:54:28 PDT 1990
4428 Add 'reset' command.
4430 Wed Apr 18 09:48:07 PDT 1990
4431 After opening remote tty, wait for 1 second to go by without input
4432 from it before trying to talk to NINDY (fixes problems with the
4433 Heurikon HK80/V960E).
4435 Mon Apr 4 16:33:05 PDT 1990
4436 Some output was not being suppressed in 'batch' mode.
4438 Thu Mar 22 15:31:11 PST 1990
4439 Ask user if old symbol table should be deleted when new file is
4442 Allow user to run a program downloaded before gdb960 was brought up.
4444 Correct "exec-file" help message for i80960 context.
4446 Correct bug in calculating user space address: could occasionally
4447 corrupt user program.
4449 Make sure to zero low-order bits in rip's because of bug in 960CA
4450 A-step part: could cause operation faults when "next"ing across
4453 Correct bug that made it impossible to get source line numbers for
4454 code loaded at addresses higher than 0x7fffffff.
4456 Wed Jan 10 12:43:22 PST 1990
4457 Open remote tty for exclusive use.
4459 Fri Jan 5 12:14:42 PST 1990

4463 Mon Oct 23 12:03:04 PDT 1989
4464 Use G960BASE and G960BIN environment variables to find 'sx' utility.
4466 Mon Oct 16 14:15:09 PDT 1989
4467 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
4469 Mon Oct 2 15:56:31 PDT 1989
4471 Added 960CA disassembly support.
4473 To simplify maintenance:
4474 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
4476 - eliminated opcode.h: incorporates tables into i960-pinsn.c
4477 - moved 960-specific routines from i960-pinsn.c to i960-md.c
4478 - made disassembly interface identical to that in gdmp960.
4482 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
4484 * target.h: Allow targets to stack. Add target_has_memory,
4485 _registers, etc. Restructure memory access and "info files"
4486 to walk the target stack.
4487 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
4488 target.c: Change tables to match target.h.
4489 * inflow.c (child_mourn_inferior): pop child_ops.
4490 (generic_mourn_inferior): Use new has_stack flag.
4491 * infptrace.c (child_xfer_memory): New memory regime.
4492 * inftarg.c (child_files_info): New "info files" regime.
4493 * remote-eb.c: New memory regime, new info files.
4494 * remote-vx.c: New memory regime, new info files. Now use
4495 separate targets for VxWorks attachment to machine, and
4496 actually running a process under VxWorks, since one has
4497 stack & execution & regs and the other doesn't.
4498 * remote.c: New memory regime, new info files.
4499 * sparc-xdep.c (fetch_core-registers): New memory regime.
4500 * target.c: New routines and support for stacked targets,
4501 new memory regime, new info files regime.
4504 Generalize section handling for an arbitrary number of sections,
4505 including use of the new BFD (binary file) library.
4506 * gdbcore.h: Add struct section_table.
4507 * exec.c (build_section_table): Iterate all sections and
4508 record what gdb needs to know about them.
4509 (exec_command): Use it.
4510 (exec_xfer_memory): Use the table.
4511 (exec_files_info): Print the table.
4512 * core.c (core_file_command, core_xfer_memory, core_files_info):
4514 * source.c (find_source_lines): Use bfd_get_mtime.
4515 * dbxread.c: Quick changes to make it compile with new BFD.
4516 * utils.c (error): Avoid using bfd_error in generic routines.
4518 * core.c (core_fetch_registers): Get from the ".regs" section of
4520 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
4522 * inferior.h (attach_flag): Export.
4523 * infcmd.c (run_command): use new target_create_inferior.
4524 * infrun.c (child_create_inferior): Don't return result.
4525 * Makefile.dist (VERSION): 3.91.4.
4527 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
4529 * breakpoint.c (bpstat_num): Handle breakpoints which have
4530 since been deleted, such as temporary breakpoints.
4531 infcmd.c (program_info): ditto.
4533 * core.c (core_file_command): Display the frame where the core
4538 * remote-vx.c (target_command): Merge in target command from
4539 targ-vx.c. A few other cleanups.
4541 * TODO, Projects: Lots more stuff to do...
4543 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
4545 Massive changes to wall off the remote-debugging interface
4546 behind a function vector. The port to handle VxWorks targets
4547 is also part of this.
4549 All files: Replace references to renamed functions,
4550 remove references to remote_debugging, remove references to
4551 have_include_file, have_core_file in favor of target_has_stack,
4552 target_has_memory, etc.
4554 * Modularize the breakpoint interface.
4555 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
4556 a breakpoint instruction.
4557 breakpoint.c: struct breakpoint's shadow_contents now sized as
4559 (insert_breakpoints): Vector to target to install breakpoints.
4560 (remove_breakpoints): Vector to target here too.
4561 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
4562 sparc-tdep.c (single_step): Use new breakpoint interface for
4563 the single-step breakpoints.
4564 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
4565 New file, contains routines to insert and remove breakpoints by
4566 reading out the old contents and later replacing them. This is
4567 how ptrace breakpoints work, and many remote systems as well.
4569 * tm-vxworks68.h: New config file, overrides a few things for
4570 Wind River's preferences.
4572 * target.h: New file, for transfer vector used to talk to the
4573 inferior (child, attached, core, exec, remote, etc). All accesses
4574 to the thing being debugged should come through these vectors.
4575 target.c: New file, routines to handle transfer vector.
4576 (various files): Add transfer vectors XXX_ops for the various
4577 targets and pseudo-targets (core files, etc) we support.
4579 * breakpoint.c (bpstat_stop_status): Further explorations of
4580 watchpoints and why things don't work all the time.
4581 (bpstat_alloc): New fn to allocate a bpstat and chain it.
4583 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
4584 the local gdbinit if it doesn't already have it.
4586 * core.c (core_ops): add and install.
4587 Allow core debugging without exec file.
4589 * dbxread.c (free_and_init_header_files): Merge two fns.
4590 (end_symtab): Free named symbol table when a new version comes in.
4591 (read_dbx_symtab): Relocate all kinds of symbols with base
4592 address. First step toward handling different text, data, bss
4594 (add_file_addr_command): Renamed add_file_command.
4595 (add_file_command): Vector to remote handler.
4596 Add "load" as an alias for "add-file" command.
4598 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
4599 non-returning functions.
4601 * exec.c: Add exec_ops, and push it as a target when an exec
4604 * infcmd.c (run_command): Pass executable file name and arg list
4605 separately when starting an inferior. Permit "run" when no exec
4606 file is specified, for VxWorks.
4607 (detach_command): Move to child_detach in inftarg.c.
4609 * inftarg.c: New file. Unix-child-specific routines, and the
4610 child_ops structure.
4612 * inferior.h (registers): Export "registers" as the way for
4613 target dependent register handlers to find gdb's local copy of
4614 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
4615 since it is now used by places that want wait_for_inferior to
4616 handle the grunge but want to see every trap from the inferior.
4618 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
4619 Eliminate remote_debugging hooks in terminal handling.
4621 * infrun.c: Replace start_inferior with child_create_inferior.
4622 Move all the hair of Unix shells and ptrace idiosyncracies into
4623 child_create_inferior, so remote handlers don't have to deal.
4624 Remove running_in_shell. Rename stop_after_attach to
4625 stop_soon_quietly, and use it in a few other places where we want
4626 to just call wait_for_inferior and get control back on the first
4627 trap. trap_expected now never takes a value > 1.
4628 (init_wait_for_inferior): Initialize static vars when a new
4631 main.c (gdbinit): Add new hook for .gdbinit file name, let
4632 it be overridden by config files as GDBINIT_FILENAME.
4633 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
4634 Both of these are used for VxWorks gdb.
4636 mcheck.c: rename include file "gmalloc.c" to avoid problems
4637 with system include file "malloc.c".
4639 param-no-tm.h: New include file, same as param.h but does not
4640 include the default "tm.h" file. This is used in files where
4641 the target is known, e.g. remote-eb.c or sparc-xdep.c.
4643 param.h: Now just a shell that includes tm.h and param-no-tm.h.
4645 remote-vx.c: New file, VxWorks remote debugging support. Uses
4646 RPC routines that are shared with the target system, in directory
4649 remote.c: Vectorize remote interface.
4651 source.c: Globalize source_path, and make an alias "l" for "list"
4652 since we now have the "load" command.
4654 sparc-xdep.c: Use new param-no-tm.h.
4656 symmisc.c (free_named_symtab): Add new function from Wind River.
4657 However, ifdef it out for now while we think about what it should
4660 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
4662 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
4663 non-Unix-children handle this with their own code in the target
4666 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
4667 source and target lists. Add vx-share to default list of include
4668 directories. Add new files to src and target lists: mem-break,
4669 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
4670 ${srcdir} versions of munch and createtags are used.
4672 * valops.c (find_function_addr): Split out of call_function.
4673 (call_function_by_hand): Rename call_function; this function
4674 calls functions in the target by laboriously patching the target
4675 word-by-word with the right stack, args, regs, etc.
4678 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
4680 Handle AMD 29000 a bit better.
4682 * remote-eb.c (readchar): Mask received char log to make it readable.
4683 (remote_start): Pass arguments down to executing program.
4684 Make startaddr unsigned.
4685 infrun.c (start_inferior): Accept args, pass them to
4687 infcmd.c (run_command): Pass args down to start_inferior.
4689 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
4690 the target object file format.
4691 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
4693 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
4694 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
4696 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
4698 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
4699 * TODO: We did a few things, we have more to do though.
4701 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
4702 * inflow.c (inferior_died): Clear deferred stores.
4704 * Debug problems with dummy frames and calls to the inferior.
4705 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
4706 * sparc-tdep.c (do_restore_insn): Simplify.
4707 (sparc_frame_find_saved_regs): Simplify and fix what we find.
4708 (sparc_push_dummy_frame): Simplify and fix what we push.
4709 (sparc_pop_frame): Slightly more hair here, deciding whether
4710 we are restoring a saved PC or returning to a return address in %i7.
4711 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
4713 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
4714 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
4715 * obstack.h (chunkfun): ditto.
4716 * defs.h (xmalloc, xrealloc): ditto
4718 * utils.c (quit): Grab the terminal from the child if necessary.
4720 * inflow.c (term_status_command): Rename to term_info, change
4723 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
4724 (is_delayed_branch): Speed up.
4725 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
4726 Still missing some float ops, and needs testing.
4728 * Support for input and output radixes other than base 10
4729 * defs.h (input_radix, output_radix): Declare.
4730 * expread.y (yyparse, parse_number): Handle changes of input
4731 radix, and ambiguous names-or-numbers in radixes >10.
4732 * printcmd.c (print_scalar_formatted): Print formatted hex
4733 numbers in varying column widths.
4734 * valprint.c (val_print): Use output_format to print scalar ints.
4735 (set_input_radix, set_output_radix, set_radix): Create.
4736 (set_output_radix): Set output_format from output_radix.
4737 (_initialize_valprint): add `set radix' but leave the others off.
4739 * main.c (execute_command): Let stupid questions be turned off.
4740 (_initialize_main): Handle "set stupidity", etc.
4742 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
4743 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
4745 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
4747 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
4748 bfd stuff is still screwed up, but with some manual work, it
4751 * breakpoint.c (bpstat_do_actions): Start over if a command
4752 proceeds the inferior, since the inferior will have stopped and
4753 will need to have its new stop-actions taken care of.
4755 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
4756 compiler fits, simplify it.
4758 * gdb.texinfo (directory command): Doc new dir command.
4759 source.c (directory_command): "dir" now puts things on the front
4760 of the path, moves dups up front, and handles multiple names
4761 on the command line, inserting each one in order. It also
4762 blows away cached line and full_filename info.
4764 * stack.c (backtrace_command): Skip "more stack frames follow"
4767 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
4768 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
4769 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
4770 The only odd one was Gould NP1, which had defined vprintf to
4773 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
4774 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
4775 variable, inspect_it.
4776 valprint.c (print_string, val_print): Use the global inspect_it
4777 to indicate whether to print in Epoch style or normal style.
4779 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
4781 * printcmd.c (call_command): add an alias for the "print" command
4782 which runs expressions and doesn't print the result if void.
4783 (print_command_1): implement it.
4785 * command.c: Remove #if 0'd code. Initialize all the fields
4786 in add_cmd (). Rename do_nothing_command to
4787 not_just_help_class_command, and make it externally visible.
4788 command.h: add user_commands to struct.
4789 * main.c (define_command): Don't overload c->function with a char
4790 string as well as a function pointer.
4792 * eval.c (evaluate_subexp): Reinstall tiemann changes to
4793 calling convention of value_struct_elt () that got dropped in
4796 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
4797 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
4799 * tm-sparc.h (POP_FRAME): replace some constants with defines.
4801 * sparc-xdep.c (store_inferior_registers): defer stores to regs
4802 until a good time (e.g. when we are about to run the child),
4803 saving ptrace calls.
4804 * infrun.c (proceed): handle DO_DEFERRED_STORES.
4805 * tm-sparc.h: define DO_DEFERRED_STORES.
4807 * sparc-xdep.c (store_inferior_registers): when storing float
4808 registers, don't store stack regs too. When storing the SP,
4809 however, DO store the stack regs too. This fixes a bug in which
4810 the dummy frame is not recognized when a call_function finishes,
4811 because its frame pointer (in the stack regs) was never
4813 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
4814 even though we don't know how to read them from an inferior.
4815 valops.c (call_function): Comment about storing SP.
4817 * infrun.c (save_inferior_status): Save away the original bpstat
4818 chain so it can be restored later. Install the copied version for
4819 use by whoever saved the status. It will be blow away by
4820 restore_inferior_status, and the original chain restored. This is
4821 important for people who have pointers into the original.
4823 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
4824 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
4825 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
4828 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
4830 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
4831 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
4832 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
4834 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
4836 * Merge Mike Tiemann's multiple inheritance changes from Sun.
4837 Store the baseclasses in a type struct starting from array element
4838 0 rather than from the unusual array element 1.
4840 dbxread.c: the above.
4841 (virtual_context): Add
4842 Read new debug information about which virtual function table
4843 a virtual function is from, and store it in fn_field.fcontext.
4845 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
4846 TYPE_FN_FIELD_STATIC_P.
4848 symtab.c: the above.
4849 valops.c: the above. Handle pointer casts of object *'s.
4850 (search_struct_method): Add.
4851 (value_struct_elt): First arg is now a pointer to a value, and is
4854 valprint.c: the above.
4855 values.c (value_virtual_fn_field): Add type arg. Handle
4856 offsetting to the proper object when calling virtual fns.
4858 (baseclass_addr): Add valuep arg.
4860 * README: Document the current state of BFD config (missing).
4861 * TODO, ChangeLog, Makefile.dist: Roll version.
4862 * WHATS.NEW: Add summary of changes since 3.5.
4864 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
4866 * dbxread.c (read_struct_type): Clear bit vectors whenever
4868 symtab.c (B_CLRALL): define.
4870 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
4871 using == rather than =. Huh... This fixes the dreaded problem
4872 wherein builtin_type_int becomes TYPE_CODE_FLT.
4874 * core.c (info_files): Show the inferior pid.
4876 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
4877 already knows how to look in the source directory.
4879 * Remove psymtab hair from many places. Remove duplicated code
4880 for searching symbol tables. Hide psymtabs from most places.
4881 Make it fast to get from a psymtab to its symtab.
4883 blockframe.c (blockvector_for_pc): Remove psymtab hair.
4884 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4885 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4886 dbxread.c: export psymtab_to_symtab, make it work if called N times.
4887 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
4888 new symtab completely. New psymtabs get symtab pointer
4889 initialized to zero. Remove MI warning printf.
4890 symtab.h: Comments. Add psymtab to symtab pointer.
4891 (PSYMTAB_TO_SYMTAB): New macro.
4892 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
4893 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
4895 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
4897 (print_frame_info): Avoid special-casing symbols that have not yet
4900 * source.c (open_source_file): Quick path if we have already
4901 located the source file by its full name.
4903 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
4904 find_pc_psymtab. When a name is found in the misc function
4905 vector, search the symbol table for its mangled name, not the
4906 name that the user typed.
4908 * bfd.h: Fix missing comment terminators, make #endifs match.
4910 * valarith.c (value_less): Handle unsigned int comparisons.
4911 Add FIXME about pointer compares, which assume host and target
4912 pointers are the same.
4914 * command.c (do_nothing_command): lint
4915 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
4916 fix comments on debug symbol format for visibility. Actually set
4917 visibility of symbols.
4918 main.c (echo_command): lint; use <readline/history.h>.
4919 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
4920 obstack.h (_obstack_blank): Rearrange pointer math to avoid
4921 pointing past end of allocated memory; saber complains.
4922 obstack.h: Declare the external functions that we use.
4923 valarith.h: use <string.h>
4924 solib.c (solib_add): lint.
4926 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
4928 * main.c (initialize_main): Default info_verbose to off, now that
4929 symbol reading is fast.
4930 (quit_command): Avoid clobbering exec_bfd while quitting.
4932 * Initial BFD (binary file diddling library) merger:
4933 coffread.c: Change AOUTHDR to struct exe_hdr.
4935 core.c: initialize initialized data at compile time.
4936 (core_file_command): Move from coredep.c, convert to bfd.
4937 (xfer_core_file): Convert to bfd.
4938 exec.c (exec_file_command): use bfd routines.
4940 mips-tdep.c: Remove exec_file_command and friends.
4943 * coredep.c: (fetch_core_registers) Convert core_file_command to
4944 fetch_core_registers.
4945 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
4947 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
4948 (my_bfd_read): More bogosity, which I don't think we call.
4949 (program_name): Remove this atrocity asap!
4951 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
4954 values.c: allocate_repeat_value was not clearing the
4955 optimized_out field.
4956 (value_static_field): minor stylistic fix (wrong macro was used).
4957 valops.c (value_struct_elt_for_address): didn't work for C++
4960 * signame.c (_initialize_signame): Initialize signal names once.
4962 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
4963 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
4964 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
4966 * remote-eb.c: Support user-settable baud rates on the serial port.
4968 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
4970 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
4972 * tconfig/sun3os4: Remove warning about native assembler,
4973 since it also occurs in the xconfig file.
4975 * findvar.c (registers): Allocate some slop after `registers'
4976 to prevent stray accesses from trashing the next variable.
4978 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
4979 on the sun-3, by changing the #ifdef from `sun3' (which is not
4980 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
4981 vars, which happened to follow `registers' in the executable.
4983 * readline/history.c (history_search): Heed gcc-2's advice
4984 and parenthesize && inside ||).
4986 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
4987 tm-29k.c: Insert FSF copyright headers.
4989 * remote-eb.c: Better comments.
4991 * Makefile.dist: Update to 3.91.6.
4992 * TODO: note PREPARE_TO_STORE problem.
4994 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
4996 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
4998 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
5000 * infrun.c (wait_for_inferior, at end): Don't set up
5001 prev_* if the inferior no longer exists.
5003 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
5004 CANNOT_EXECUTE_STACK.
5005 valops.c (call_function): Use it.
5007 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
5009 * inferior.h (PC_IN_CALL_DUMMY): New macro.
5010 infrun.c (wait_for_inferior, 2 places): Use it.
5012 * values.c (value_being_returned): Only use
5013 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
5015 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
5016 right thing for remote-eb.c.
5018 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
5019 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
5021 * blockframe.c: Put get_frame_saved_regs inside #if !defined
5022 (FRAME_FIND_SAVED_REGS).
5024 * findvar.c ({fetch,store}_registers): Check for
5025 REMOTE_{FETCH_STORE}_REGISTER macro.
5027 * findvar.c (get_saved_register): Add argument lval and
5028 change meaning of argument addr.
5029 findvar.c: Change calls to get_saved_register to reflect
5030 new calling convention.
5031 valops.c (value_assign): Use get_saved_register instead of
5032 find_saved_register.
5034 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5036 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
5037 an (uninitialized) pointer to one. Use "&" when passing it
5040 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5042 * coffread.c (getfilename): Use DGUX x_offset and x_name if
5045 * coffread.c (symbol_file_command): Put semicolon after
5047 Put safe_to_init_tdesc_context in #if defined (TDESC).
5048 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
5049 coffread.c: #include <sys/stat.h>.
5050 (read_coff_symtab): Typo: in_source_files -> in_source_file.
5051 Add missing ')' in check for "lc%" and friends. Remove
5053 Declare read_one_sym() at top of file.
5054 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
5055 MC68WRMAGIC can have the same value without causing a duplicate
5058 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
5060 * Allow a Makefile to be built without building the
5061 tm and xm file links that screw up builds in subdirectories.
5062 This is done with `config.gdb none', then you can do things
5063 like `make gdb.tar.Z'.
5064 * tconfig/none: Config file for no target system
5065 * xconfig/none: Config file for no host system
5066 * config.gdb: If no TM or XM files are called out by the
5067 host or target file, don't make links for them.
5069 * cplus-dem.c: Add documentation.
5071 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
5072 simple error, so the user's gdb doesn't crash due to some object
5073 file problem (e.g. somebody is rebuilding the file out from under
5076 * printcmd.c (print_address_symbolic): demangle the symbol.
5078 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
5079 Motorola copyrights in it. Make "make gdb.tar.Z" work.
5080 (alldeps.mak): sort and uniq all results from this; duplicates
5081 hose gdb.tar.Z link building. Remove RCS files from
5082 tconfig and xconfig. Add config files for sun386. Add
5083 a few odd files to OTHERS and HFILES.
5085 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
5087 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
5088 Roll version number to 3.91.5. Make lint work in bindir.
5090 * README: Document cross-debugging and new file structure.
5092 * blockframe.c: Lint. Include "value.h" to declare read_register.
5093 (find_pc_partial_function): remove duplicate line.
5095 * command.h: Lint. Declare error_no_arg and dont_repeat.
5097 * tm-news.h: Remove inadvertently duplicated stuff.
5099 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
5100 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
5102 * config.gdb: Allow `config.gdb host target' form. Clean
5103 up previous change that printed bogus messages when you just said
5106 * core.c: #include "command.h" for lint.
5109 * main.c: Remove some casts of enums. Lint.
5116 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
5118 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
5119 read it from memory. This will allow us to save ptrace calls
5120 eventually. Changed caller single_step too.
5122 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
5123 that we aren't going to use, saving many ptrace calls, especially
5124 when watchpointing or single stepping. Use some #define's for
5126 (store_inferior_registers): Ditto.
5127 (core_file_command): Use some #define's for constants.
5129 * tm-sparc.h: Add #define's for some register numbers, so we
5130 can eliminate the use of random constants in sparc-xdep.c.
5132 * stack.c (frame_command, print_frame_info, up_command,
5133 down_command) Remove frame_changed, since it
5134 causes a bug and doesn't seem to do anything useful. In some
5135 places it was used as a flag, in others as a stack level (?).
5137 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
5138 default is to use the portable (vprintf) version rather than the
5140 * xm-news.h (MISSING_VPRINTF): Add.
5142 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
5144 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
5146 * Remove stuff that forces -Bstatic linking of gdb, and warnings
5147 about linking debugged programs -Bstatic in the sun?os4 config
5148 files in tconfig and xconfig subdirectories.
5150 * main.c (main): Remove unreached exit(0) now that we exit
5153 * Create TODO file for online bug list. There are too many
5154 "little" bugs to keep track of on paper.
5156 * Change Projects file to refer to bug-gdb@cygnus.com
5157 rather than kingdon@ai.
5159 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
5161 * Makefile.dist (VERSION): 3.91.4 now.
5163 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
5164 (condense_misc_bunches): Add sanity check that misc_count is
5165 the same as the number of symbols in the bunch.
5167 * coffread.c: rename init_misc_bunches. Pass an argument
5168 to condense_misc_bunches (a zero).
5170 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
5171 every time we are called; don't rely on our caller to do it.
5172 (add_file): Remove call to init_misc_bunches.
5174 * mipsread.c: Only warn, don't error, if unknown symbol types.
5175 This keeps an old gdb from falling on its face if it sees newly
5176 extended symbol info. Rename init_misc_bunches.
5178 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
5180 * Merge in changes from Per Bothner for DECstations and other
5181 MIPS stuff. The rest is Bothner speaking:
5183 The next message is a merger of Alessando Forin's mips port with
5184 mine. I've tried to use my good if biased judgment to get
5185 the best of both. It *does* need testing.
5187 Some of the changes are general, *not* mips-specific.
5190 Didn't believe in little-endian bit order.
5191 There are still inconsistencies about whether flags
5192 like BITS_BIG_ENDIAN are integer (#if ...) or
5193 boolean (#ifdef ...). I tried to paper over them.
5195 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
5196 Moved some misc_function code that was common to
5197 {dbx,coff,mips}read.c to symtab.c.
5198 In the process, I think I cleaned things up a bit.
5199 At the same time, moved obsavestring and obconcat to symtab.c.
5202 Removed obsolete condense_addl_misc_bunches (use
5203 condense_misc_bunches(1) instead).
5206 Needed to include <sys/dir>, at least on DECstations.
5208 valops.c, mips-tdep.c, tm-mips.h:
5209 Added PUSH_ARGUMENTS macro to support funny argument-pushing
5210 conventions (when STACK_ALIGN is insufficient).
5211 Needed on mips, where doubles need 8-byte alignment,
5212 but ints only need 4.
5215 Removed cruft that was not being used.
5216 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
5219 Print $ before register-names (I think that makes things a little
5221 Never print two instructions, even if one delays.
5222 Removed hex-disassemble set_cmd. (This is not mips-specific,
5223 so I think the argument is whether it is generally worthwhile or not.
5224 I'm inclined to think not, given how easy it is to
5225 convert between radixes in gdb.)
5228 This is basically Alessando's code.
5229 It doesn't use obstacks; I changed it to use obstacks
5230 in a few minor places where using malloc causes a
5231 memory leak. (Probably, more places could/should be changed.)
5232 I added record_misc_function where it was missing.
5233 In symbol_file_command and add_file_command, I tried
5234 to make the code consistent with more recent versions.
5235 Minor sylistic changes in parse_procedure.
5236 Make a .gdbinfo. psuedo-symbol point back to the real
5237 procedure symbol (using the isym field).
5240 This is basically from my port, but with a lot of details
5241 and a number of routines merged in from Alessando's version.
5242 I basically used my code "raw" backtrace (use heuristics
5243 from the actual code, rather than symbol table info) - though
5244 the idea is Alessandro's. I feel my code is a little cleaner
5245 here, particularly in being a little more flexible, such as being
5246 able to handle gcc-produced code (which it now can).
5247 It also doesn't do frame caching (which is not useful
5248 more recent gdb versions).
5249 I also used my code for push_/pop_dummy, more or less.
5250 I tried to incorporate AF's code for testing sigtramp
5251 while backtracing; I probably got it wrong.
5252 Added mips_print_register, which tries to scrunch as much
5253 information as possible on a screen...
5254 Removed the skip-prologue set_cmd. As with hex-disassemble (see
5255 under mips-pinsn.c), I don't see anything mips-specific here,
5256 and I don't see it being all that useful anyway.
5259 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
5260 Use more register names (rather than hard-cases numbers).
5262 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
5264 * Hack up 3.90.11 changes:
5266 * Makefile.dist (depend): parameterize $(GCC).
5267 Add solib.c and solib.o.
5268 (readline): Fix vpath for both absolute or relative SRCDIR.
5270 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
5271 Also, let the part I didn't understand at least compile so
5272 I can test the rest. FIXME.
5274 * dbxread.c: Fix thinko using strcmp.
5275 (init_psymbol_list): declare static.
5276 (partial_symbol_file_open): Comment cleanups better, avoid
5277 cleaning up the string table since the caller will do that.
5278 Move the stat for mod time into symbol_file_command, temporarily.
5279 (There should be a mod time for each symbol file, eventually,
5280 to control its rereading. FIXME.)
5282 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
5283 SunOS, which gives error for shared libs otherwise. (From
5284 Schaefer, probably FIXME needs work for portability.)
5286 * solib.c: Move #include "param.h" to work.
5287 Lowercase all the Uppercase Letters In the Messages.
5288 (find_solib): Clean up inferior_so_name for debug printouts.
5289 Allow no argument, to mean all shared libraries.
5291 * symmisc.c: include param.h to get CLEAR_SOLIB.
5293 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
5295 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
5296 to 3.90.11. ChangeLog entries below are from this.
5298 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)

5304 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5308 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
5310 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)

5314 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5316 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
5317 Put parens around gcc_p in expansion.
5319 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5321 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
5323 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5325 * Changes for Sun shared libraries:
5326 blockframe.c (find_pc_partial_function): If a non-text symbol
5327 is found, set *address = pc - FUNCTION_START_OFFSET.
5328 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
5329 Disable breakpoints instead of giving an error.
5330 source.c (select_source_symtab): Initialize cs_pst.
5331 symmisc.c: Call CLEAR_SOLIB if defined.
5332 symtab.h: Make text{low,high} CORE_ADDR not int.
5333 (psymtab): New field addr.
5335 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
5336 (record_misc_function): Give correct type for N_DATA symbols.
5337 (condense_misc_bunches): do "misc_function_count = j" regardless
5339 Take code which is shared between symbol_file_command and
5340 add_file_command and put it into partial_symbol_file_{open,read}.
5341 Split add_file_command into add_file_command and add_file.
5342 Make psymtab_to_symtab read in the string table if the file
5344 Two new parameters to read_dbx_symtab and start_psymtab.
5345 tm-sunos.h: New file.
5347 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5349 * infcmd.c: Change cont_command to continue_command and "cont"
5352 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5354 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
5356 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
5358 * values.c (USE_STRUCT_CONVENTION): Check for structures of
5359 size 1,2,4,8 rather than size < 8.
5361 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
5362 as necessary, not just once.
5364 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
5366 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5368 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
5370 * tm-news.h: Add CALL_DUMMY_*.
5372 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
5374 * config.gdb: In list_host, list_target, use ${i}, not $i.
5376 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5378 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
5380 * sparc-opcode.h: Change all store floating-point state register
5381 instructions to have the right match & lose fields.
5383 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5385 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
5387 config.gdb: If srcdir != ., create readline directory and
5388 copy a makefile into it.
5390 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
5391 consistency with POSIX.
5393 * breakpoint.c (bpstat_stop_status): Disable watchpoint
5394 when we exit its exp_valid_block.
5396 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
5398 * Makefile.dist: Bump version to 3.91.3.
5400 * Clean up handling of breakpoint commands (somewhat).
5401 Prompted by Tiemann bug report "cont 10" doesn't work any more.
5403 inferior.h: Add breakpoint_proceeded to inferior status struct
5404 and globals; save it and restore it.
5405 (clear_breakpoint_commands): Cleanup, remove old #define.
5407 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
5408 (save_inferior_status, restore_inferior_status): handle it also.
5409 (proceed): Remove earlier code that set breakpoint_proceeded.
5410 It is now set only in clear_proceed_status.
5411 (clear_proceed_status): Cleanup, use bpstat_clear rather
5412 than clear_breakpoint_commands. No callers need the stop_bpstat
5413 between clear_proceed_status and proceed.
5415 infcmd.c: Add breakpoint_proceeded definition and comment.
5416 (cont_command, jump_command, signal_command): Move call to
5417 clear_proceed_status right next to call to proceed.
5419 breakpoint.c (bpstat_do_actions): Avoid clobbering our
5420 caller's argument while running down the chain of breakpoints.
5421 Use new variable "breakpoint_proceeded" to determine when
5422 a command that it executes moves the inferior past the
5424 (bpstat_clear): Handle NULL argument.
5425 (bpstat_clear_actions): Avoid useless call to
5426 breakpoint_auto_delete.
5427 (delete_breakpoint): Clean up bpstat's that are pointing to
5428 the deleted breakpoint from the stop_bpstat chain.
5429 (breakpoint_auto_delete): Simplify.
5431 * Clean up handling of EOF, error on stdin, etc. This was
5432 prompted by a network problem that caused gdb to go into an
5433 infinite loop filling up its malloc'd memory.
5435 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
5436 not clear_breakpoints_commands, which is now gone.
5437 (main): If command_loop returns (e.g. from EOF on stdin), do
5438 a quit_command (looping back to command_loop if quit_command
5439 doesn't really quit).
5440 (command_loop): check result from command_line_input and
5441 exit if it returns NULL, rather than passing the NULL to
5443 (gdb_readline): Free malloc'd result space before returning
5446 * utils.c (query): Handle C-d to mean "yes", just as if the
5447 input was not a terminal. Also avoid infinite loop if EOF
5448 occurs in mid-input-line before newline. This allows
5449 query to be used at EOF on stdin with reasonable results.
5451 * infrun.c (proceed): Set breakpoint_proceeded.
5453 * values.c (value_as_long): Avoid infinite recursion for enums.
5454 (_initialize_values): Fix typo in help msg (kingdon).
5456 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
5457 RL_LIB for linking. This allows -lreadline for linking
5458 and nothing for dependencies, once readline is a real library.
5460 * config.gdb: Jim Kingdon: give useful error message if the
5461 host or target type is not recognized.
5463 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
5464 it just defines it. Dumb, but deal with it.
5466 * Jim Kingdon suggests:
5467 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
5469 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
5471 * Makefile.dist (VERSION): Bump version # to 3.91.2.
5473 * Clean up Bothner's changes.
5475 * blockframe.c (clear_pc_function_cache): New function.
5476 * blockframe.c: remake cache_pc_function_* static.
5477 * dbxread.c (symbol_file_command): remove references to
5478 cache_pc_function_* variables.
5479 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
5480 * printcmd.c: Avoid kludging a global variable (addressprint)
5481 to avoid printing the address of a string twice. Instead,
5482 pass the format letter 's' down low enough that it can be seen
5483 to avoid this problem.
5484 (print_formatted): Pass format arg to value_print.
5485 (restore_addressprint): Remove function.
5486 (do_examine): Avoid hacking addressprint, cleanups and such.
5487 (print_frame_args): Add a comment to a Bothner change.
5488 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
5489 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
5490 to wipe out the values cached in blockframe.c.
5491 * symtab.c (find_method): Add comment saying how big you must
5492 allocate to be "big enough". Per being terse again.
5493 * valprint.c (val_print): Handle format letter "s" to print
5494 strings without addresses. Add comment to vtbl printing code
5495 which casts with wild abandon. Rearrange reference-printing
5497 @0xaddr: value (print w/addressprint)
5498 value (print w/~addressprint)
5499 @0xaddr (parameter lists w/addressprint)
5500 or nothing (parameter lists w/o addressprint)
5502 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
5504 * Merge more changes from Per Bothner:
5506 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
5507 annoying) that I tried to improve it. Here are my suggestions.
5509 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
5512 Do automatic de-reference when taking the address of a reference.
5514 Don't deref_ref when printing parameter lists.
5516 More attempts at treating refernences properly.
5518 In val_print, if deref_ref==0, don't print dangling " = ".
5520 Add COERCE_REF macro, which de-references an REF.
5522 * Merge changes from Per Bothner:
5524 * Fixed (Sony news)-specific configuration problems.
5525 * Fixed other problems with using vanilla pcc and libc (enum problems;
5526 assumption that vsprintf exists).
5527 * Some major speed-ups (finc_pc_partial_function now caches a match;
5528 parsing avoids duplicate symbol_lookup calls).
5529 * Changed handling of baseclasses (no longer use baseclasses field
5530 of struct type, use the first n_baseclasses fields instead).
5531 * Various minor changes/fixes, most C++-related.
5534 Cache the most previous match from find_pc_partial_function.
5535 (Save both low and high ends of matching function's pc range.)
5536 This speeds up the loop of infrun.c:wait_for_inferior quite
5537 a bit, and makes step/next commands much zippier.
5539 Added an enum->int cast (otherwise, some compilers barf).
5541 No longer set baseclass offset to 0, since multiple
5542 inheritance now mostly works.
5543 Added a number of casts, to shut up compiler warnings
5544 (after stabs where made enums, not ints).
5545 When discarding a symbol table (in symbol_file_command),
5546 must clear the cache introduced in blockframe.c.
5547 Don't convert $vtbl_ptr_type to vtbl any more.
5548 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
5549 Mask off sign bit emitted by g++ for virtual table offset.
5550 Set voffset to -1 (not 1) for static member functions.
5552 Changed parsing/lexing of names to avoid doing symbol lookup twice
5553 (once when lexing to determine symbol class, once for real).
5554 Now only call symbol_lookup once. Fields of 'this' win especially big.
5556 Subpress printing addr twice in the case of 'x/s addr'.
5558 lookup_basetype_type is no longer used.
5559 Add find_methods as recursive helper function to decode_line_1.
5560 This allows multiple inheritance to work.
5561 Also, once one or more matches has been found, do not look in
5562 base-classes. (Baseclass methods would be overridden, anyway.)
5564 Removed baseclasses array in struct type.
5565 Instead of using baseclasses[i], use fields[i-1].
5566 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
5567 Changed sign convention of voffset (previous was inconsistent).
5569 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
5571 Used to assume existence of vsprintf. Re-written to not need it
5572 if HAVE_VPRINTF is undefined.
5574 typecmp was too pessimistic. Made it less so.
5576 Don't print space after address.
5577 If vtable points to a misc symbol (with 0 offset), print it,
5578 since that indicates the actual class of the object.
5579 Changed ype_print_derivation_info to use new inheritance
5580 scheme (without baseclasses vector).
5582 In value_primitive_field, fixed some bugs left over from previous set of fixes.
5583 Also, changes needed because TYPE_BASECLASSES were removed.
5585 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
5587 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
5590 If there is no path set, and the symbols don't indicate what directory
5591 a file was compiled in, look in the current directory. But either
5592 a path or a known compilation directory will prevent this.
5595 Three independent bug fixes:
5596 * Remove the #if 0 block that breaks some stuff.
5597 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
5598 adapt gdb to either SunOS 4.0.* or 4.1.
5599 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
5602 Instantiate the class T when looking for methods in it. (Tiemann@sun)
5605 (type_print) Demangle the name being printed.
5606 (type_print_base) Handle botched demangling without coredump (tiemann).
5609 (check_stub_method): Document routine.
5610 (tiemann) fix bug for no-arg functions
5611 Avoid clobbering beyond end of malloc'd storage.
5612 Terminate the argument list properly.
5614 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
5616 * Changes merged by John Gilmore:
5619 In breakpoint_1, use new print_address_symbolic instead
5620 of find_pc_partial_function. (This forces use of assembler-level
5621 addresses, and avoids misleading non-mangled source-level names.)
5623 Generalize ansi argument such that -1 means skip arglist totally.
5624 Removed global variable print_ansi_qualifiers (which made
5625 code non-reentrant), in favor of extra explicit arguments
5626 to internal routines.
5628 Add new helper function print_address_symbolic.
5629 Use find_pc_misc_function instead of find_pc_partial_function
5630 (since we want assembler-level symbols here).
5632 Print unknown function as just "f (...)", not "f (...) (...)".
5633 Use new fputs_demangled explicitly.
5635 Fixed a typing violation (problem: value.h cannot be imported
5636 without renaming many variable in this file).
5637 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
5638 decode_line_1: Moved forward some never-reached code.
5639 Made decode_line_2 skip function prologues correctly.
5641 fputs_filtered should not demangle by default.
5642 Add new fputs_demangled to demangle on demand..
5644 Change value_struct_elt to use value_primitive_field (using recursive
5645 utility function search_struct_field). This allows foo.bar to work
5646 for multiple inheritance (so far only for data fields).
5647 Change check_field in the same way (recursive helper function
5648 to support multiple inheritance).
5649 (Note: there are more of these problems that I haven't fixed.
5650 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
5651 value_of_this: 'this' symbol name is now just "this", note "$this".
5653 Don't print static members.
5654 Avoid printing "members of <type>" if there are none.
5655 Simplified type_print_derivation_info by merging duplicate code.
5656 Remove useless blank lines in type_print_base (ptype command).
5658 Added declaration of new routine value_primitive_field.
5660 Added value_primitive_field which is generalized version of
5661 value_field that can handle multiple inheritance (non-zero offsets etc).
5662 Re-implemented value_field to call value_primitive_field.
5664 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
5666 * infcmd.c -- insert else to avoid 'delete env' coredump when you
5667 delete the whole environment. Karl Berry reported the bug.
5668 * source.c - fix openp to avoid //'s in filenames, which
5669 trigger an Emacs bug causing it to not be able to find files
5670 when running gdb in a window.
5671 * dbxread.c - zap the #if 0 that botches the add-file code.
5672 It seems to work a lot better without all the code commented out.
5674 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
5676 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
5679 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
5681 * Makefile - added a ${CFLAGS} to a couple of entries,
5682 added remote-sa.sparc.c
5683 * added remote.sa-sparc.c, a modification of remote.c
5684 which conducts a dialog directly with the SparcStation prom.
5685 * breakpoint.c, infrun.c, sparcdep.c added
5686 remote_insert_breakpoint(), and remote_remove_breakpoint()
5687 to breakpoint.c instead of directly writing breakpoint instructions.
5688 * sparcdep.c on remote_debugging,there is no need
5689 to remove signle step breakpoint instructions.
5690 * main.c added "-epoch" flag and "int epoch_interface" to main.c
5692 * printcmd.c - epoch interface sends lisp expressions to open up
5693 epoch windows on inspection.
5694 * valprint.c - added arrayprint, and addressprint and made adding
5695 format controls easier
5696 * wait.h added a couple of undef's because we were getting
5697 complaints about WSTOPSIG and WTERMSIG begin redefined.
5700 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)

5722 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
5724 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
5725 should print ANSI qualifiers (such as `const' and `volatile').
5726 All callers changed to call with ANSI == 1, except from
5727 `check_method_stub', which uses old-style syntax.
5729 * symseg.h (struct fn_field): Remove unneccessary `args' field.
5730 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
5732 * values.c (check_stub_method): New function.

5749 Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla)
5751 * blockframe.c (blockvector_for_pc): New function.
5752 * blockframe.c (block_for_pc): Changed to call
5753 `blockvector_for_pc' and get the block itself.
5755 * stack.c (catch_info): New function. Prints info about
5756 exceptions which can be caught in the current frame.
5757 * stack.c (print_frame_label_vars): New function. Similar to
5758 `print_frame_local_vars'.
5759 * stack.c (print_block_frame_labels): Prints out labels that are
5760 defined in this frame. These labels are exceptions that can be

5765 Thu May 3 22:10:00 1990 Michael Tiemann (tiemann at teacake)
5767 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
5768 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
5769 when printing the type.
5771 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)

5784 Fri May 4 12:12:55 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5786 * breakpoint.c (watch_command, bpstat_stop_status): Deal with
5787 exp_valid_block field correctly.
5789 * infrun.c (wait_for_inferior): When checking "don't even think
5790 about breakpoints" if stop_signal == SIGTRAP && trap_expected,
5791 also check step_resume_breakpoint.
5792 Insert breakpoints and continue (not step) if
5793 step_resume_break_address != NULL, even if another_trap.
5794 If trap_expected and we enter sigtramp, then set up a
5796 If trap_expected is set when we hit the step_resume_break,
5798 When calling resume and trap_expected says tell resume to step
5799 (2 places), also check step_resume_break_address.

5960 to remote_fetch_registers.
