3 * symtab.c: Make internal errors produce more useful messages.
5 * tm-68k.h: Move code that is duplicated in almost every single
6 m68k based machine's configuration files to this common file.

11 setpgrp() with no arguments, to comply with prototyping typically
14 * munch: Add support for SVR4 style nm output.
16 * dbxread.c, mipsread.c symmisc.c, symtab.c: Remove the object
17 file specific fields from the partial symbol table structure and
18 replace them with a pointer to private data for each different
19 flavor of object file reader to initialize appropriately.

53 * tm-i386v.h: #endif guck.
54 * xconfig/i386*: Remove -Dgetpagesize()=4096 kludge.
55 * xconfig/i386sco: Add HAVE_STRSTR to avoid ANSI bdeath.
56 * xconfig/tahoe: Add REGEX, which seems to be missing.
58 * coredep.c: Add <sys/types.h> for SCOnix.
59 * dbxread.c (read_dbx_symntab): Avoid coredump on malformed file.
60 * printcmd.c (print_formatted): Flush output before disassembly.

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

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

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

266 and restore the language string after giving help.
267 * valprint.c (typedef_print): Print typedef in C or M2.
268 * symtab.c (list_symbols): Use it.
269 * main.c (main): Avoid any output before (gdb) prompt when -q.
270 * language.c (set_language_command): Handle errors by restoring
271 the language string to its current state (fix from A. Beers).
272 * doc/gdbint.texinfo: Roll in information from README. Rearrange

275 * configure.in: Rename rtpc CPU to romp to match config.sub.
276 * README, WHATS.NEW, TODO: Update for gdb-4.1.
278 Fri Sep 20 17:39:14 1991 Roland H. Pesch (pesch at cygnus.com)
280 * doc/gdb.texinfo: Updates from ChangeLog. set/show write,
281 autoloading shared libs, copyright etc on GDB startup, clean up $_
282 and $__ index refs, set/show listsize and related updates to list
283 cmd. New host/target configs.
285 Fri Sep 20 15:46:00 1991 Roland H. Pesch (pesch at cygnus.com)
287 * doc/Makefile: generate aux version-no file doc/gdbVN.m4
288 from main Makefile.in version definition
289 doc/gdb.texinfo: use version recorded in doc/gdbVN.m4 for current
291 Makefile.in (setup-to-dist): generate doc/gdbVN.m4
293 * doc/gdb.texinfo: merge new language-switching and lang-specific
296 Fri Sep 20 15:00:57 1991 Per Bothner (bothner at cygnus.com)
298 * mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
299 compilers (which may lack stddef.h).
301 Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com)
303 * dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and
304 N_WARNING are the same except for the N_EXT bit, so just use their
305 values alone, rather than OR-ing them with N_EXT.
307 Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com)
309 * mipsread.c (parse_lines): Deal with negative extended line
312 * c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid
313 global symbol conflicts.
315 Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
317 * .gdbinit: Move 'set complaints' to top, so it runs even in
318 case we aren't debugging GDB.
319 * language.c (_initialize_language): Fix type check and range
320 check documentation strings.
321 * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
322 language.c can use it. (Though language.c should really not be
323 handling warnings/errors the way it does, FIXME.)
324 * symtab.c (lookup_primitive_type): const lint.
326 Bugfix from Peter Schauer:
327 * source.c (lines_to_list): Make signed, to avoid comparison
328 going unsigned and complaining that -3 is too high for 21 lines.
329 * stack.c (lines_to_list): Ditto.
331 Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
333 * Makefile.in (HFILES): Add minimon.h.
334 (VERSION): Roll version number to 4.0.95.
335 (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
336 New rules for building distributions. Normal distribution
337 is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
338 one level up from here; it calls make-proto-gdb.dir to build a
339 directory `proto-gdb' which is an image of the release. The old
340 `gdb.tar.Z' rule still works too.
341 * config.sub, configure: Roll in latest from ..
343 Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
345 * doc/gdbint.texinfo: Reorder contents; reorganize new-host,
346 new-target, and new-config chapters; fix minor typos; come closer
347 to usual GNU markup conventions for @file @samp @code @var.

351 Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
352 * mipsread.c (parse_partial_symbols): Enter the name of all
353 structs/unions... into the psymtab so we can access them if the
354 symtab is not read in.
355 * mips-tdep.c: Remove some unneeded #includes.
356 * xconfig/dec3100: Add HAVE_STRSTR.
358 Thu Sep 19 15:14:23 1991 John Gilmore (gnu at cygnus.com)
360 * Makefile.in: Circumvent Sun Make bug on *-exp.tab.o.
361 * c-exp.y, m2-exp.y: Lint.

364 * mipsread.c (_initialize_mipsread): Avoid using
365 builtin_type_void at initialize time.

467 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
469 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
470 entries are enclosed herein. Not all of these changes
471 have been merged into the master GDB sources -- check the
472 ChangeLog above here for the merge log.
474 Mon Jun 3 17:05:45 EDT 1991
476 m2-exp.y Created. Tested outside of GDB for a few days. Proper
477 operators were added, C specific operators and tokens
478 removed. yylex() revamped to some extent. Still things
479 missing from the grammar, such as sets.
480 Tested for two weeks in GDB v3.5.
482 Tue Jun 11 17:23:48 EDT 1991
484 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
485 so they are built-in. Sort of a hack.
487 Fri Jun 14 12:53:51 EDT 1991
489 m2-exp.y Added range checking for numeric constants. Any numeric
490 constant is assumed to be of builtin type INTEGER unless:
491 (1) it is octal or hexadecimal, in which case it is a
492 CARDINAL; (2) it is too big to fit into an INTEGER, in
493 which case it is a CARDINAL.
494 eval.c Added simple range checking for +, -, and * on integers.
495 Doesn't work very well for *, since 6 * 1,000,000,000 =
496 1,705,032,704, which fails the simple test of result >=
497 first_operand, no matter in what order the operands are.
499 Tue Jun 18 14:11:30 EDT 1991
501 Broke the parser into parts, one containing the C grammar and the other
502 containing code to be shared by all of the grammars.
504 The following files no longer exist:
509 The following files were added:
511 c-exp.y (The C grammar)
512 m2-exp.y (The Modula-2 grammar)
513 parser-code.c (Code that is shared by the above grammar)
517 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
518 now necessary to use the Bison compiler compiler, since it
519 will generate function/variable prefixes other than yy.
521 Tue Jun 18 16:47:49 EDT 1991
523 symtab.[ch] Added the external variable working_lang, than holds the
524 value of the current working language.
525 Added the ennumerated type language_mode, with the values
526 language_auto and language_manual, the former meaning that
527 GDB sets working_lang as needed, and the latter meaning
528 that the value of working_lang is totally under user
530 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
531 REAL, BOOLEAN and CHAR. Also added the type codes
532 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
533 utils.c Added set_language_command and show_language_command to
534 implement the GDB support commands "set language" and
536 expression.h A number of identifiers were added to the type exp_opcode
537 to facilitate Modula-2 builtin functions, integer
538 division, and array indexing.
540 Wed Jun 19 13:25:58 EDT 1991
542 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
543 if the language specified by working_lang requires the use
544 of strict typing of expressions. Eventually, even this
545 will be able to be changed by the user.
546 Added the macro RANGE_CHECK, which evaluates to non-zero
547 if the language specified by working_lang requires the
548 checking of a value against the domain of its type.
549 Eventually, even this will be able to be changed by the
551 language.[ch] Predicates involving types (simple_type, ordered_type,
552 same_type, integral_type, numeric_type, character_type,
553 boolean_type, float_type) are added. These predicates are
554 based on the current value of working_lang, and are handy
557 Wed Jun 19 15:39:34 EDT 1991
559 eval.c Added the function type_array_rank which computes the rank
561 valarith.c Added the funtion value_bool, which when given a integer
562 value.h value (ie. struct value *) as an argument, it returns a
563 boolean value (ie. struct value *) true if that integer
564 is non-zero, and a boolean value false otherwise.
565 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
566 will print out properly.
568 Wed Jun 19 16:36:34 EDT 1991
570 valops.c Added the function value_capitalize, which returns it
571 value.h argument capitalized if its argument is a lowercase
572 letter, or the argument unchanged if its argument is not a
574 valarith.c Added the function range_check_p, which returns non-zero
575 value.h if its value argument is between the integral bounds upper
577 Added the function range_check_enum_p, which makes sure
578 that its value argument is a valid member of the domain of
580 Added the function range_check_range_p, which makes sure
581 its value argument lies between the upper and lower bounds
582 of its type argument, which must be a ranged type.
583 Added the function check_array_index, which range and type
584 checks an index of an array.
585 Added the function value_multi_subscript, which computes
586 array[idx1,idx2...idxN], given a value array and an array
587 of values representing indicies.
588 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
589 unpack_long to work with TYPE_CODE_BOOL and
592 Wed Jun 19 18:04:08 EDT 1991
594 symtab.c Stored pervasive types in a structure and make
595 lookup_pervasive_type() a lookup function that was based
596 on working_lang. If lookup_pervasive_type() returned
597 non-zero, then that value was returned (a fix, since
598 before it simply wouldn't return the pervasive type.)
599 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
600 non-zero if the language specified by working_lang means
601 "conversion" when it says "cast".
602 valops.c Added the function value_real_cast(), which performs a
603 value.h *cast*, not a *conversion*, which is what value_cast()
604 does when it can. In particular,
605 value_cast(<float_type>,4) = 4.0, while
606 value_real_cast(<float_type>,4) = some mess.
607 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
608 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
609 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
610 and MIN on integral types. *NOTE*: These are currently
611 hardcoded to work only if there are 8 bits per storage
613 eval.c Made logical functions call value_bool to return a
614 properly typed boolean value, based on working_lang.
616 Thu Jun 20 11:55:27 EDT 1991
618 valprint.c Types now print out in a Modula-2 fashion. This works for
619 the cases when the type is printed out step-by-step, that
620 is, it doesn't work when the name of a structured type
621 (which includes the keyword "struct", etc.) is simply
623 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
624 since type specifications in C and Modula-2 are very
625 different. The C printing of a type is very recursive,
626 whereas in Modula-2 it is generally very simple. C has
627 type prefixes and suffixes, which have no real analogue in
628 Modula-2. Maybe type_print() should call a language
629 specific type printer. This is also advantageous if we
630 compile GDB to exclude some of the languages. We'll just
631 leave those functions out.
633 Thu Jun 20 16:57:10 EDT 1991
635 dbxread.c When reading the complete symbol table in (via
636 psymtab_to_symtab()), the number and types of function
637 arguments are added to a function type. define_symbol()
638 calls add_param_to_type() to accomplish this.
639 Assumption: when we come across a function definition
640 (N_FUN symbol with an 'f' or 'F' in the name), its
641 arguments will appear before another function definition.
642 When a function is found, a pointer to its type is placed
643 in the global in_function_type. Changes that
644 add_param_to_type() makes are to this global.
645 valprint.c The type of a function now includes (for Modula-2) the
646 types of its parameters.
647 eval.c Type checking and a check for the proper number of
648 arguments is now done for function calls. Not sure of the
649 impact this has on C++ member function yet.
651 Thu Jun 20 19:58:48 EDT 1991
653 valprint.c Rewrote the type printer. Broke it into two language
654 specific parts, adding the functions type_print_m2() and
656 An unfortunate consequence is this: if you debugging a C
657 program in Modula-2 mode (why?), info types does not work
658 well with regular expressions, since the types are printed
659 out in Modula-2 terminology, but stored in C terminology.
660 language.[ch] Added the functions new_type_last(), type_keyword(), and
661 type_sep() to aid in the printing of typedefs.
662 symtab.c Made the printing of typedefs as language independent as
663 possible through calls to new_type_last(), type_keyword(),
666 Fri Jun 21 11:50:26 EDT 1991
668 dbxread.c Check all incoming ennumerated types. If it looks like
669 Modula-2's BOOLEAN type, then change the type_code of the
670 type to TYPE_CODE_BOOL so we can process it as a boolean
672 valprint.c Replaced some of the 0x%x with calls to sprintf and
673 hexformat() in val_print().
674 language.[ch] Added the function hex_to_string(), which converts its
675 integral argument to a hexadecimal number (format is
676 language based) and returns the result as a string.
678 Mon Jun 24 12:25:07 EDT 1991
680 valprint.c Some functions call type_print_1() directly, instead of
681 value.h using type_print(), so they can specify where (column) to
682 print things. Since type_print() takes care of language
683 dependence, that needs to be called first. Added a
684 parameter depth to type_print() (so it is now like
685 type_print_1). Changed type_print to type_print_at, and
686 made type_print a macro that passes a depth argument of
688 symmisc.c Changed all calls to type_print_1 to calls to
690 Makefile.dist Made it possible to build GDB for a specific set of
691 depend languages. Do this by passing a definition for the macro
692 LANGS to make. LANGS should be a string containing a
693 space-separated list of language names (ie. LANGS="c m2").
694 The default is to build all languages. Note that grammar
695 files must follow the naming convention of <lang>-exp.y.
696 gdb.lang This holds the current value of the LANGS macro. It is
697 examined every time make is called, and is updated if
699 eval.c Added #ifdef _LANG_<lang> to these files.
700 expread.c Still need to add them to dbxread.c and coffread.c.
708 Mon Jun 24 16:33:11 EDT 1991
710 language.[ch] Added the functions hexformat_pre() and
711 hex_to_string_pre(), which take a prefix argument to
712 include in the format string. Thus, hexformat_pre("08") will
713 return "0x08x" (if the working language is language_c).
714 Made hexformat() and hex_to_string() calls to the above
715 with "" as the prefix argument.
717 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
718 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
719 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
720 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
721 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
722 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
723 valprint.c, vax-pinsn.c
725 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
726 calls to hexformat() and hex_to_string(). Format strings without
727 the leading "0x" were ignored.
729 depend Updated to take the above into account.
732 Tue Jun 25 15:27:18 EDT 1991
734 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
735 and type_check_t to keep track of the current state of
736 range and type checking.
737 main.c Added the variables range_mode, range_check, type_mode,
738 and type_check to record the current state of range and
739 type checking. Added initialization code to main().
740 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
744 Tue Jun 25 17:57:08 EDT 1991
746 dbxread.c process_one_symbol() updates the variable (enum language)
747 source_lang based on the extension of the filename
748 contained in the N_SO sybmol that started this symtab.
749 When end_symtab() is called, the value of source_lang is
750 put into the language field.
751 stack.c select_frame() sets working_lang (and possibly type_check
752 and range_check) to the language field of the symtab
753 associated with the frame that is selected if working_mode
754 is language_auto. If working_mode is language_manual, a
755 warning is printed and working_lang is not set.
756 language.c Added the function set_type_range(), which sets the value of
757 type_check and range_check (if their modes call for
758 automatic setting) based on the current value of
759 working_lang. A non-zero argument will cause the current
760 settings to be output.
763 Wed Jun 26 14:51:40 EDT 1991
765 eval.c Added range checks on assignment.
766 m2-exp.y Added the grammar for sets to the language. Currently,
767 these do not do anything except print an error message.
769 Wed Jun 26 17:01:04 EDT 1991
771 m2-exp.y Added the ability for parse_number() to parse negative
772 numbers. A global flag is set upon encountering a unary
773 minus. This was done to make, for example, 1 parse as a
774 CARDINAL, and not as an integer, per Wirth's examples in
775 Programming in Modula-2 ed.4.
776 valprint.c Added support for "set radix 2" by then setting
777 output_format to 't'.
778 eval.c Implemented range checking on subrange types. Added calls
779 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
780 Implemented MIN and MAX for ennumerated types. The
781 minimum value of an ennumerated type is defined by Wirth
782 as the first identifier, and the maximum as the last.
783 m2-exp.y Made octal numbers ending with "B" be characters and those
784 ending with "C" be numbers, per Wirth's book. (p. 34)
786 Thu Jun 27 14:11:52 EDT 1991
788 stack.c select_frame() now only sets working_lang, it does not
789 notify the user. If working_mode is language_manual, then
790 a warning is issued once.
791 main.c At the end of each call to execute_command(), working_lang
792 is checked against the local static (enum language)
793 current. If they differ and working_mode is
794 language_auto, the new settings of language, type and
795 range checking are printed out.
796 stack.c Modified frame_info() to include the language of the
797 current frame in the output of "info frame".
798 language.[ch] Added the function language_str() which returns the name
799 of the current language.
801 Fri Jun 28 15:33:14 EDT 1991
803 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
804 the language. INCL and DECL currently cause an error,
805 since sets are not implemented yet. INC and DEC are
806 implemented as PREINCREMENT/PREDECREMENT with one
807 argument, and as ASSIGN_MODIFY with two arguments.
808 eval.c Added type checking to the above cases.
809 value.h Added not_lval_constant to the lval_type ennumerated type.
810 not_lval_constant means that the value is a constant
811 value; that is 3 or 'a' or TRUE, not as in a constant
812 identifier. This is used to help coerce numbers such as 3
813 to either signed or unsigned numbers.
814 valops.c Added the function value_coerce_constants() which coerces
815 constant integers as following: if one is a constant and
816 the other is not, the constant's type is set to the type
817 of the other argument. If both are constants and one is
818 signed, the other is converted to a signed constant.
820 Sat Jun 29 17:26:29 EDT 1991
822 valarith.c Added a better range checker. It now checks range
823 (successfully) on integral operations [+-] (signed and
824 unsigned) for any C sized type. Still does not work well
826 int_in_size() returns an integer that is coerced to fit into
827 specified number of bytes.
829 Mon Jul 1 13:04:14 EDT 1991
831 language.[ch] Added the function binop_result_type(), which returns the
832 builtin (struct type *) type that would be the result of a
833 binop on the two values V1 and V2.
835 Wed Jul 3 19:22:53 EDT 1991
837 source.c Extended source_info() to include the source language in
838 the output from "info source".
840 Fri Jul 5 13:48:52 EDT 1991
842 utils.c Moved the support functions for the GDB set/show commands
843 dealing with language into language.c.
844 language.c Added the function language_info(), which displays info
845 about the current working language, type and range check
846 settings. Called via the GDB command "info language".
847 Added an initialization routine _initialize_language(),
848 that sets defaults for the language, type and range
849 variables and sets up the new GDB commands.
850 main.c Language setup moved to language.c.
853 Mon Jul 8 10:10:22 EDT 1991
855 valarith.c Debugged the range checker for arithmetic. Still does not
856 work for multiplication very well.
858 Mon Jul 8 12:40:37 EDT 1991
860 language.[ch] Added the function value_true() which returns non-zero if
861 its argument represents a boolean true value.
862 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
863 check the truth of an expression.
865 Thu Jul 11 12:51:34 EDT 1991
867 language.[ch] Added the predicate structured_type(), which returns
868 non-zero if the argument is a structured type.
869 Added the predicate pointer_type(), which returns non-zero
870 if the argument is a pointer type.
871 eval.c Added the ability to do addition and substraction on
872 pointers and integers. This case simply bypasses the
875 Thu Jul 11 14:41:42 EDT 1991
878 Added the symbol N_DEFD (0x4a) which is a definition
879 module dependency that is used by the GNU Modula-2
880 compiler and the linker. It is not important to GDB,
881 except that [dbx|coff|mips]read.c should ignore these
884 Fri Jul 12 16:07:00 EDT 1991
886 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
887 0 in val_print(). Also added statements to the else part
888 to coerce type (argument to val_print) to a pointer type
889 if it is an "array of unspecified length".
890 valops.c Added the function value_m2_string(), which returns a
891 (value) value which is a constant string, whose type is
892 (ARRAY [0..n] OF CHAR). The length field of the type
893 structure is set to zero, so it will be interpreted as an
894 "array of unspecified length".
895 stack.c Moved the language/frame mismatch check to
896 main.c:execute_command().
897 main.c The working language is recorded each time
898 execute_command() is executed. If working lang has
899 changed during its execution, then the new
900 language/type/range info is printed out for the user. If
901 the working language does not match the language of the
902 frame, a warning is issued.
904 Sat Jul 13 16:16:39 EDT 1991
906 eval.c Moved all the type-checking stuff for operators to
907 language.[ch] language.c. This is so we can keep language-specific
908 stuff (like for what type operators are defined) in
910 language.[ch] Added the function binop_type_check(), which checks to see
911 if its two (value) arguments are type-compatible with its
912 opcode argument. The opcode should represent an operation
913 involving an operator. Also added the macro function
914 unop_type_check, which calls binop_type_check with a
915 NULL second argument.
916 expprint.c Added Modula-2 operators to the op_print_tab, so info
917 expression.h break works correctly. Also added "op_string", which
918 returns the string corresponding to the (enum exp_opcode)
919 opcode that is its argument.
922 Sat Jul 13 18:26:18 EDT 1991
924 coffread.c Added code to record the type of function arguments with
925 each paricular function. Code is very similar to that
927 dbxread.c Moved add_param_to_type() to symtab.c
928 symtab.[ch] Added function add_param_to_type() from dbxread.c
930 *** NOTE: The above additions have not been tested.
932 Mon Jul 15 12:50:47 EDT 1991
934 langauge.[ch] Added the functions type_error and range_error, which work
935 like error() except if the type/range mode is set to
936 *_mode_warn, then they do not do a return_to_top_level(),
937 but merely print a warning.
938 Also changed [set|show]_[type|range]_command() to support
939 the new "warn" feature.
941 Thu Jul 18 17:50:54 EDT 1991
943 mipsread.c Added code to record the type of function arguments with
944 each particular function. Code is very similar to that
947 *** NOTE: The above additions have not been tested.
949 Fri Jul 19 11:19:10 EDT 1991
951 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
952 UMIN_OF_SIZE, which when given a size of a numeric type,
953 return the maximum and minimum value it can hold. UMAX...
954 and UMIN... return the result for unsigned types.
955 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
956 struct types. They call above macros.
957 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
958 avoid a name conlict with the above.
959 c-exp.y Added range checking on numeric constants in
960 parse_number() for completeness.
961 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
962 return 0 if working_lang is not language_c.
964 Thu Aug 8 14:17:22 EDT 1991
968 breakpoint.c Documentation strings of some commands changed to
969 eliminate the references to the C language where
972 Tue Aug 13 15:48:03 EDT 1991
974 m2-exp.y Added qualified identifiers to the grammar. The semantics
975 are slightly different from those of the GDB operator ::
977 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
978 type_exp, where type_exp is any valid type expression.
980 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
981 printcmd.c Modified ptype_command() so it actually parses the input
982 (necessary for type expressions with scope qualifiers).
983 Added the function ptype_eval() which expects an
984 expression composed of one OP_TYPE element.
985 *.[ch] Replaced all occurences of parse_c_expression with
987 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
989 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
991 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
993 Small fixes from Peter Schauer:
995 * infrun.c (child_attach): Lint.
996 * solib.c (find_solib): Handle shared libs version 2.
998 Small fixes from David Wood:
1000 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
1004 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
1005 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
1007 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
1008 chars_per_line is at maximum (user typed `set width 0'). Fix
1009 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
1011 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
1013 * coredep.c: include ptrace.h where necessary.
1014 * mipsread.c(parse_lines): fix unsigned char problem that was
1015 messing up line numbers on SGI's and possibly other MIPS based
1017 * infrun.c (child_create_inferior): use better test to check
1018 return val from setpgrp().
1019 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
1020 for sgi/irix support.
1022 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
1024 * mipsread.c (parse_symbol): Put non-static procedures
1025 in the global block.
1027 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
1029 Patch together `text_start' and `text_end' for 29K port.
1031 * exec.c (exec_command): If NEED_TEXT_START_END, define the
1032 variables and set them based on the exec file.
1033 * am29k-tdep.c: declare text_start.
1034 * valops.c (call_function_by_hand): declare text_end.
1036 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
1037 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
1038 because machines that do this will also have to know to
1039 set NEED_TEXT_START_END. Besides, it was a redundant way to
1041 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
1042 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and

1045 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
1047 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
1049 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
1050 Pass MUNCH_DEFINE to munch whenever we run it.
1051 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
1052 format string; use 0x%x instead.
1053 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
1054 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
1055 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
1056 * inflow.c: Handle `short' process group IDs.
1057 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
1058 and check for ptrace errors.
1059 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
1060 (coff_symfile_init): Initialize text_bfd_scnum.
1061 (read_coff_symtab): Use it to find the text [and absolute?] sections.
1062 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
1063 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
1064 Merge target arm case with other "easy" cases. Add target
1065 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
1066 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
1068 * minimon.h, remote-adapt.c, remote-mm.c: Add.
1069 * munch: Cope with RT/PC putting fns in data segment.
1070 Restore ability to override `nm' by specifying MUNCH_NM.
1071 * xconfig/rtbsd, xconfig/ultra3: New host systems.
1072 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
1073 and remote-adapt. Remove encapsulated coff #define's (the
1074 support should go in BFD, and gdb shouldn't know or care).
1075 * tconfig/a29k-kern: Same, but for remote kernel debugging.
1076 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
1077 * tm-29k.h: Update BADMAG (though it should go away).
1078 Allow the register definitions to be overridden in another
1079 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
1080 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
1081 DUMMY_SAVE_GR96, for handling kernel calling conventions
1082 that use GR64+ rather than GR96+.
1083 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
1084 remote debugging of Ultra3 kernel. Includes tm-29k.h and
1085 overrides various things.
1087 * remote-mm.c (mm_attach, mm_wait): Handle attach like
1088 child_attach does, making a clean stop in the newly attached
1090 * remote-eb.c: Lint.
1092 * coffread.c: Make coffread independent of any particular
1093 variant of COFF. Avoid #include-ing any particular one except
1094 internalcoff.h. BFD now passes key values for symbol reading
1095 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
1096 and the symbol masks and shifts); use them.
1097 Remove obsolete end_of_text_addr.
1099 * exec.c: Remove unused include files.
1101 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1103 * Makefile.in (documentation targets): Pass $(M4).
1104 Bugfix from eggert@twinsun.com (Paul Eggert).
1106 * stack.c (down_silently_command): Check for stack existence.
1108 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1110 * Makefile.in (VERSION): Update to 4.0.3.
1112 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1114 * core.c (core_file_command): Print frame at coredump with
1115 its level number, by calling print_stack_frame.
1116 * frame.h: Add selected_frame_level, print_stack_frame.
1117 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
1118 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
1119 Change print_sel_frame and print_selected_frame callers to
1122 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
1123 * symfile.c (free_named_symtabs): Ditto.
1124 * main.c (main): wrap_here needs an arg.
1125 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
1126 (solib_add): Avoid noise.
1127 (solib_create_inferior_hook): Lint.
1128 (sharedlibrary_command): Move dont_repeat to here.
1129 * utils.c (error): Call wrap_here to force buffered output.
1131 Small patches from Peter Schauer:
1133 * coffread.c (start_symtab): Free any existing line_vector before
1135 (read_coff_symtab): Ditto for type_vector.
1137 * source.c (lines_to_list): New variable, replacing function.
1138 (all uses): Use as variable.
1139 (_initialize_source): Add 'set listsize' and 'show listsize'.
1140 * utils.c (lines_to_list): Remove function.
1141 * stack.c (print_frame_info): Use as variable.
1142 * defs.h (lines_to_list): Remove declaration.
1144 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1146 * breakpoint.c (insert_breakpoints): Restore warning about
1147 the program might be running in another process, but only for
1148 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
1149 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
1151 * utils.c (error): if error_pre_print is set, print the string
1153 * main.c (main, print_gnu_advertisement, print_gdb_version):
1154 Reformat legalese so it always prints, but acts as an "I'm here"
1155 message while symbols are being read. If any errors occur,
1156 print a few newlines to set off the message and start it at the
1157 left margin. Remove mention of "help" command, and don't yak
1158 about symbol reading.
1159 (catch_errors): Error string is now printed first in case of
1161 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
1162 suggest the "help" command.
1164 * Makefile.in (VERSION): Set to 4.0.2.
1166 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
1168 * .gdbinit: Remove useless "rr" command. Set complaints
1169 to 1 for people debugging gdb.
1171 * breakpoint.c, remote-vx.c: Reword strings printed by
1172 catch_errors callers.
1174 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
1176 * WHATS.NEW: "history write -> history save". Doc "write on/off".
1177 (Fix from kenc@viewlogic.com.)
1179 Fix some infrastructure to be able to cope with host and target
1180 machines with different sized basic types (ints, ptrs, etc).
1181 (Idea from pierre@la.tce.com (Pierre Willard).)
1183 * values.c (value_from_longest): Rename from value_from_long.
1184 Handle pointer types as well as integers, so that targets with
1185 different pointer sizes from the host can be accomodated.
1186 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
1187 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
1188 uses of value_from_long to value_from_longest.
1189 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
1190 the correct pointer type to value_from_long{est}.
1192 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
1194 * remote-vx.c: Remove obsolete code for calling functions via
1195 vxworks kludge interface (it referenced value_from_long).
1197 * valops.c (value_string): Find malloc with lookup_misc_func, not
1200 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1202 Make writing to files work properly. (Fixes to BFD are also needed.)
1204 * core.c (core_open): Open file ourselves, read or r/w, depending on
1205 write_files. Use bfd_fdopenr.
1206 * gdbcore.h (write_files): New variable.
1207 * exec.c (write_files): Define variable, add set&show for it.
1208 (exec_file_command): Use write_files to open for read or r/write.
1210 Make shared library reading happen automatically. These changes
1211 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
1213 * inferior.h (stop_soon_quietly): Add to exported variables.
1214 * infrun.c (child_create_inferior): call solib hook, if defined.
1215 (child_attach): call solib hook, if defined.
1216 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
1217 (find_solib): Use lookup_misc_func rather than hand-rolled.
1218 (symbol_add_stub): New stub for catch_errors.
1219 (solib_add): Avoid output if !from_tty. Catch errors rather
1220 than just calling symbol_file_add and bombing.
1221 (solib_create_inferior_hook): Interface with the target process
1222 to let it read and alloc shared libs, then figure out what it did.
1224 * core.c (validate_files): Fix typo, soften warning.
1225 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
1227 * utils.c (fputs_demangled): Avoid duplicate printing if
1228 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
1230 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
1231 (Fix from pierre@la.tce.com (Pierre Willard).)
1233 * main.c (catch_errors): Change argument to a char * from an int,
1234 since a char * can point to a struct full of glop, but an int
1235 is not guaranteed to be able to hold a pointer.
1236 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
1237 breakpoint_re_set_one, breakpoint_re_set): Adapt.
1238 * core.c (core_open, solib_add_stub): Adapt.
1239 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
1241 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1243 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
1244 by adding .NOEXPORT target.
1246 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1250 * Makefile.in (VERSION): Roll to 4.0.
1251 (gdb.tar.Z): Make refcard.ps as well, for shipment.
1253 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1255 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
1258 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
1261 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
1263 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
1264 reflect above name change
1266 * WHATS.NEW: correct pointer to refcard.
1268 * doc/gdb.texinfo: update New Features, Installing
1270 * doc/gdbint.texinfo: add short description of configure +template
1272 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1274 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
1276 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
1278 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
1279 tar file, add dependencies for referenced doc files.
1281 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
1283 * coffread.c, symfile.c, stack.c: saberized.
1285 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1287 * doc/refcard.tex: permuted Essential Commands sec
1289 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
1291 set/show symbol-reloading
1292 default set complaints 0
1294 RET-repeat disabled after prompted long displays
1295 processID (attach) interpretation of 2nd GDB cmdline arg
1297 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
1299 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
1300 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
1301 breakpoint.c, main.c: lint.
1303 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1305 Install new configuration scheme for GDB and friends.
1307 * config.sub: Translate ordinary names to three-part names.
1308 * configure: Use three-part names internally.
1309 * configure.in: Translate three-part names to filenames.
1311 * README, WHATS.NEW: Update for gdb-4.0.
1312 * Makefile.in: Roll VERSION to 3.99.
1314 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
1316 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
1317 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
1318 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
1319 to single structures rather than arrays; when passing
1320 their address, use &. This avoids trouble with bdead compilers.
1321 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
1322 instead. This avoids portability headaches.
1323 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
1325 * source.c (open_source_file): Avoid ANSI const bdeath by
1326 skipping declaration and then casting result value.
1327 * tm-hp300bsd.h: Clarify comment.
1328 * utils.c (strstr): Result is const char *; ANSI bdeath.
1329 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
1330 since system include file defines it differently from "defs.h",
1331 though the two are equivalent for our purposes.
1332 * tconfig/hp300bsd: Add m68k-tdep.o.
1334 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1336 * tconfig/sun*4: Remove warnings about system assembler.
1338 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1340 * mcheck.c: Avoid warning about undeclared abort fn.
1341 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
1342 it causes recursive calls to error() when used in cleanups.
1343 To do so requires that we make it a function, so we do.
1344 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
1345 * utils.c (do_cleanups): Remove the current cleanup from the
1346 chain *before* calling it, in case error() is called from it.
1347 The result won't be pretty, but won't be an infinite loop either.
1349 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
1351 * dbxread.c (read_struct_type): Grok anon structs for C++.
1352 (vb_name, vptr_name): Null terminate these strings.
1354 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1356 Minor bug fixes from BSD Net2 gdb:
1358 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
1359 returns 0, there is no previous frame.
1360 * breakpoint.c (commands_command): If !from_tty, don't call
1361 input_from_terminal_p().
1362 * dbxread.c (record_misc_function): Speed up slightly.
1363 (compare_psymbols): Ditto.
1364 * infcmd.c (do_registers_info): Take a second argument to
1365 determine whether to print float registers. "info registers"
1366 does not do so anymore. "info all-registers" does, now.
1367 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
1369 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
1370 * inflow.c (initialize_inflow): Set tflags_ours correctly.
1374 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
1375 executing_breakpoint_commands if we are interrupted by error.
1376 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
1377 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
1378 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
1379 catch_errors() so we can setup the frame regardless of whether
1380 the shared libs work.
1381 * ieee-float.c (double_to_ieee_extended): Get exponent from
1382 right place in little-endian systems. From John Carey.
1384 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1386 * main.c: Remove unused terminating_signals and catch_termination().
1387 (long_options): Terminate with a zero element.
1388 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
1389 (gdb_readline): Make call-compatible with readline.
1390 (init_signals): Improve comments re vfork vs. signal.
1392 * utils.c (prompt_for_continue): Use new gdb_readline().
1393 If we prompt for continuation, we don't let CR repeat the previous
1394 command, once we get back to a prompt. It's too easy to keep
1395 hitting CR, expecting "--more--" prompts, and have some long
1396 command start repeating on you.
1398 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1400 * blockframe.c (frameless_look_for_prologue): Speed up by
1401 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
1402 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
1403 Define two variants, one faster.
1404 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
1405 and return zero, rather than giving an error.
1406 (setup_arbitrary_frame): Initialize the PC in the new frame.
1407 (skip_prologue): Add a second arg saying whether we're just
1408 checking for a frameless function or not.
1410 * core.c (core_open, core_close, core_xfer_memory): Move
1411 section table pointers and bfd* into the target_ops.
1412 (core_open): Allow errors in shared lib reading, etc.
1413 (core_files_info): Describe shared library sections.
1415 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
1416 exec_files_info, set_section_command): Move section table
1417 pointers and bfd* into the target_ops.
1418 (add_to_section_table): Add BFD to section table.
1420 * target.c (target_xfer_memory, target_info): Pass target to
1421 xfer_memory and target_info functions.
1424 * gdbcore.h: Move struct section_table.
1425 * target.h: New home of struct section_table.
1427 * solib.c (solib_add): New argument is the target_ops whose
1428 section list is to be added to, if any. Reallocate the
1429 sections in that target to add any that come from shared libs.
1430 (throughout) so_sections renamed to sections.
1431 (solib_xfer_memory): Deleted.
1432 * tm-sunos.h (SOLIB_ADD): Add target argument.
1433 (SOLIB_XFER_MEMORY): Delete.
1435 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1436 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
1437 from target_ops. It's the same on all targets. Add two section
1438 pointers to target_ops.
1440 * stack.c (find_relative_frame): Dump ancient algorithm for
1441 "down", just use handy "next" pointers.
1442 (frame_command): Don't error if there is no stack; let user
1445 * inflow.c (new_tty_prefork, new_tty): New prefork routine
1446 modifies static state in the parent process; new_tty itself
1447 runs in the child and modifies the child's file descriptors
1448 to match the saved static state.
1449 * infrun.c (child_create_inferior): Call new_tty_prefork,
1452 * infptrace.c (child_xfer_memory): Add ignored target arg.
1453 * remote-eb.c (eb_xfer_inferior_memory): ''
1454 * remote-nindy.c (nindy_xfer_inferior_memory): ''
1455 * remote-vx.c (vx_xfer_memory): ''
1456 * remote.c (remote_xfer_memory): ''. Rename from
1457 remote_xfer_inferior_memory.
1459 * main.c (main): Only try to attach "corefile" argument if
1460 it starts with a digit.
1462 * symfile.c (symbol_reloading): New "set/show" variable.
1463 (symbol_file_add): Shorten message about symbol reading.
1464 (add_symbol_file_command): Merge with add_syms_addr_command,
1465 since this should work on all targets now.
1466 (stop_whining): Default to zero, to shut up complaints
1467 about bad symbol tables on many systems.
1468 (free_named_symtabs): Just exit unless symbol_reloading.
1470 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
1471 and add comment explaining shared library screw.
1473 * source.c: #if defined => #ifdef.
1475 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1477 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
1479 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1481 * doc/rdl-apps.texinfo: provide default readline-appendix finder
1482 (doc/Makefile knows how to make one for local config)
1484 * Makefile.in: use doc/Makefile for doc targets
1486 * doc/Makefile: GDB documentation now has its own Makefile
1487 doc/refcard.tex: renamed from "gdbrc.tex"
1488 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
1489 doc/gdbint.texinfo: add markup in "Cleanups" chapter
1492 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1494 * values.c (baseclass_addr): When reading target memory, use the
1495 length of the basetype, not the upper type. We've only malloc'd
1496 enough space for the basetype, leading to errors in free().
1498 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
1499 ends up as a function specially, since we know the actual type of
1500 the pointed-to address. This (somewhat) fixes display of
1501 expressions that include misc_function_vector names. Try `cond 1
1502 !strcmp("a","b")' then `i b'.
1504 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
1505 The child can be proceeded from inside wait_for_inferior in
1506 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
1507 getting skipped in that case.
1509 * expprint.c (print_subexp): Use filtered output, since the
1510 subroutines we call use it, otherwise the output is horribly
1511 mangled, since output of wrappable stuff comes out late.
1513 * Makefile.in: Bump VERSION to 3.98.1
1515 * infrun.c (child_create_process): Use execlp to find the
1516 shell to exec our target program. This requires some fiddling
1517 with `environ' since there is no execlpe().
1519 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1521 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
1522 Minor rearrangement of refcard permits two new make targets--
1523 gdbrc.dvi DVI output for refcard, using CM fonts
1524 gdbrc.ps PostScript refcard, using PS fonts
1526 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1530 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
1531 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
1533 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1535 * doc/gdb.texinfo: last changes for release.
1536 Minor typo and formatting fixes; incorporated most fixes remaining from
1537 filed mail commenting on earlier drafts.
1539 Added warnings: pipes don't work in run command;
1540 conditions are converse of assertions;
1541 step over fn without debug info goes to next fn;
1542 vars may have "wrong" values near fn entrance, exit
1544 Added example from Kingston on printing repeated nonadjacent values
1546 Added explicit mention that in Emacs gdb mode C-c and C-z are like
1547 shell mode for signals
1549 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
1550 doesn't sound so much like its parent "Stopping and Continuing"; also
1551 moved entries on continue to top of section, so they don't get lost.
1553 Improved installation directions in appendix, added manual formatting
1556 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1558 * configure.in: Remove xm.h and tm.h even if we aren't linking
1559 new ones, so "./configure sun4; ./configure none" does the right
1560 thing. Assume that alldeps.mak and depend are already built in
1561 srcdir, and avoid running "make" (particularly "make depend",
1562 which involves "gcc") from inside configure. Build Makefile
1563 directly rather than building Makefile.conf first.
1564 * configure: Regenerate with above changes.
1565 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
1566 to 3.98. Revise gdb.tar.Z procedure to produce a file
1567 called gdb-$(VERSION).tar.Z but which unpacks into a
1568 directory called "gdb". Move non-source files out of
1569 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
1570 (depend): Don't try to do "gcc expread.y".
1571 (expread.o): Update dependencies by hand.
1573 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1576 Fixed a variety of small typos that prevented info from formatting
1577 cleanly; altered too-long heading for GPL Appendix, as discussed
1578 w/RMS; Changed date on cover to July 91.
1580 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1583 (1) Applied some fixes due to comments from Larry Breed (easier ones
1584 through chapsec 5.2)
1585 (2) Eliminated use of @footnote---had my doubts about it anyways, and
1586 it's broken in latest texinfo
1587 (3) Introduced *some* use of [] for optional arguments, where
1588 explanation is not simpler by listing cmd w arg and cmd w/out arg
1589 separately. Still not using @deffn.
1590 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
1591 couple of headings are too long. Need patches to texinfo or revision
1594 * Partial update to README (which still needs work for this
1595 release!): (1) use of configure corrected for new script,
1596 (2) "make gdb.dvi" and "make gdb.info" mentioned.
1598 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
1600 * symtab.c (lookup_symbol): Don't complain right off about
1601 no debug symbols; use the misc function vector first.
1602 (list_symbols): Use misc function vector to find symbols
1603 that don't have debug info, and print them.
1604 (find_pc_symtab): Temporarily avoid fatal() when psymtab
1605 PC range doesn't match symtab PC range, as it does on the
1606 MIPS because our symtab reading isn't perfect.
1608 * dbxread.c (dbx_symfile_read): Make warning about
1609 "no debug symbols" slightly nicer.
1611 * source.c (select_source_symtab): If "main" symbol exists,
1612 but decode_line_spec can't find line info, don't just return
1613 a zero; try other source symtabs or give an error.
1615 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
1616 their low addresses first, then rip through fixing high addrs.
1618 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
1619 <runene@ifi.uio.no>.
1620 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
1622 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1624 * Minor, mostly mechanical, cleanup of doc subdir for clean
1625 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
1626 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
1628 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
1630 Mostly MIPS and general symbol-reading fixups.
1632 * doc/gdbint.texinfo: Add documentation on symbol-reading
1635 * mipsread.c: Remove kludges around #include "ecoff.h".
1636 Remove redefinitions of a_magic, etc, no longer used.
1637 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
1638 Fix global overview comments to match symfile.c protocol.
1639 (mipscoff_new_init): Eliminate cur_hdr if we have one.
1640 (mipscoff_symfile_read): Eliminate unused code. Avoid
1641 sorting all the symtabs, when all we have read here is psymtabs.
1642 The symtabs are sorted as they are created anyway. Tell
1643 condense_misc_bunches whether we're mainline.
1644 (psymtab_to_symtab_1): Pass filename when recursing, to make
1645 stack trace more informative.
1646 (parse_partial_symbols): Assume cur_hdr as argument.
1647 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
1648 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
1649 the TYPE_NAME of char *, since that's done in symfile.c.
1650 (free_numargs, parse_symbol, add_symbol, add_block,
1651 shrink_linetable): Declare these fns void.
1652 (upgrade_type): Convert tree of if's to switch. Clean up
1653 bogus "off == 0" handling with a complaint. Avoid setting
1654 field bitpos and bitsize of array with lower and upper bounds.
1655 Check specified bitsize of elements against their actual type's
1656 bitsize, and complain if different. Complain about unknown
1658 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
1659 (psymtab_to_symtab_1): Print names of subsidiary files that
1660 are being read in. FIXME, we read far too many files. This code
1661 is not the problem, the problem is in parse_fdr where the psymtabs
1663 (cross_ref): Result should indicate that we used one aux entry
1664 normally, or two if we encountered a "next" entry. This used
1665 to leave the caller pointing at the wrong aux entry.
1666 (add_symbol): If overflowed cur_block, reallocate it larger,
1667 chase all pointers to it, and complain(), rather than clobber memory.
1668 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
1669 (new_field): Only allocate one field initially, not two.
1670 Pull ++ out of macro argument. Simplify.
1671 (_initialize_mipsread): Avoid initialization of importd
1672 global_psymbols and static_psymbols.
1674 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
1675 to properly set pst->symtab; avoid searching for it.
1676 (symfile_fns): Improve comments, add a FIXME.
1677 * dbxread.c: Update comments to reflect symfile protocol.
1678 (read_ofile_symtab, end_symtab): Return the symtab.
1679 (psymtab_to_symtab_1): Set pst->symtab.
1681 * coffread.c (coff_symfile_read): tell condense_misc_bunches
1682 whether we're mainline.
1684 * symfile.h (sym_fns): Remove unused sym_discard member.
1685 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
1687 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
1688 the environment variable is not.
1689 * infcmd.c (finish_command): Use filtered printfs.
1690 * cplus-dem.c: Add struct tags to a few unnamed structs.
1691 * valops.c (value_coerce_array): Improve comments.
1692 * valprint.c (type_print_varspec_suffix): Print array size only
1693 if greater than zero.
1694 * m88k-tdep.c: Shift some lines left by one space, that had
1695 apparently been trashed at some point.
1696 * TODO: More things to do, a few got done.
1698 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1700 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
1701 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
1703 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
1704 * expread.y, findvar.c, symmisc.c: Ditto.
1705 * printcmd.c (address_info): Update printed forms of LOC_
1706 symbols. Elim LOC_EXTERNAL.
1707 (print_frame_args): Keep track of param stack offsets before
1708 re-looking up to find the local register param is kept in.
1710 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
1711 Further integration of mipsread into gdb. Eliminate unused
1712 routines, duplicate declarations. Handle static symbols in
1713 psymtabs as well as external symbols. When reading symtabs,
1714 insert symbols into the correct block (global, static, or a local
1716 (read_mips_symtab, parse_partial_symbols): Don't pass useless
1718 (mipscoff_symfile_read): Don't call select_source_symtab.
1719 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
1720 rather than SYMBOL_VALUE.
1721 (parse_external): Comment clobbering of top_stack.
1722 (parse_partial_symbols): Update comments. Allocate and parse
1723 static symbols as well as external symbols. FIXME, enum values
1724 are not handled in this pass, but should be. Inline new_psymbol.
1725 Use SYMBOL_VALUE_ADDRESS.
1726 (psymtab_to_symtab_1): Read symbols into global static block
1727 by default (until enter some function's local block context).
1728 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
1729 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
1731 * source.c (select_source_symtab): Select a source symtab
1732 from either the symtabs or, failing that, the psymtabs.
1733 (list_command): Update error message.
1734 (forward_search_command, reverse_search_command): Use getc, not
1735 fgetc, for speed. FIXME, add comment about buffers that die if
1736 overrun by long line.
1738 * values.c (unpack_field_as_long, modify_field): Avoid shifting
1739 by an entire word, which is not portable, if we have a 32-bit
1740 field. (Code in dbxread.c already turns such bitfields, if
1741 aligned, into ordinary ints, but fixing this will help for other
1742 symbol formats and for future changes.)
1743 * core.c (core_open): Handle ANSI const brain death.
1744 * utils.c (vprintf): Fix varargs typo.
1746 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1748 * findvar.c (find_var_value): Handle &function better.
1749 * TODO: Document work needed on &fn and &array.
1750 * printcmd.c (print_address_symbolic): New arg is the prefix
1751 to print if a name is printed.
1752 (print_address_demangle): Honor "set print address" now.
1753 Use new arg above to improve spacing of output.
1754 * valprint.c (val_print): When printing function pointers,
1755 print symbolic form too.
1756 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
1758 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1760 * core.c (memory_error): Reword error msg to mislead less.
1762 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
1764 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
1765 parse_partial_symbols): Use newer BFD internals (external_filehdr
1766 and external_aouthdr), byte-swap the fields that we care about
1767 before using them, and make the file header data local to
1768 read_the_mips_symtab rather than global.
1770 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
1772 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
1773 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
1775 * main.c (command_line_input): Flush stdout and stderr
1776 before every call to readline. This reportedly fixes a bug
1777 that comes up in Sys V running emacs-gdb and/or xxgdb,
1778 when stdin/out are pipes or sockets.
1780 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1782 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
1783 Avoid declaring Makefile dependencies, because GNU Make stupidly
1784 tries to update it if we do.
1786 * coffread.c: Revise for minor changes to bfd internal coff
1789 * configure: If -template= is given a relative path, make it
1790 absolute before recurring in subdirectories.
1792 * configure, configure.in, Makefile.in: Install "configure" script
1793 as replacement for config.gdb.
1794 * config.gdb, Makefile.dist, Makefile.sdir: Remove
1795 * README: Update for configure, mostly. FIXME.
1797 * Add dec3100 as equivalent to littlemips. Indicate in all host &
1798 target config files that they are for the host. When the lines
1799 get copied into the Makefile, this makes it more obvious what's
1802 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1804 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
1805 tabs, which end up in the disassembler output inadvertently.
1807 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1809 Make it compile cleanly in an ANSI GCC2 environment.
1811 * blockframe.c: <stdio.h>
1812 * cplus-dem.c: free takes a void *, ifdef __STDC__
1813 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
1815 * defs.h (alloca): Avoid doing anything if alloca already def'd.
1816 * stddef.h, stdlib.h: Remove these files.
1817 * symtab.c: Avoid declaring qsort, close.
1818 * symfile.c: Avoid declaring close.
1819 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
1820 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
1822 Assorted other changes.
1823 * dbxread.c: include "libaout.h", not "liba.out.h".
1824 * printcmd.c (print_frame_args): Set recurse properly for
1825 indentation of struct and array parameters.
1826 * valops.c (value_cast): Allow cast to void.
1827 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
1828 single_step() in a target-independent fashion.
1829 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
1830 set up to be ready to continue. This makes us target independent.
1831 * infptrace.c (child_resume): Remove call to single_step; now
1832 can single step a SPARC target of any kind.
1834 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1836 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
1837 docn into separate sections---basically chapters, plus two loose
1838 pieces that can be configured to go in different places. This
1839 allows GNU m4 to preprocess the manual without coredumping.
1841 * Makefile.dist: tell TeX where to find texinfo.
1843 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1845 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
1846 the new target "rdl-apps.texinfo" which captures the Makefile
1847 variable that records where to find the Readline libraries.
1849 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
1851 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
1852 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
1853 * defs.h (const, volatile): Only define if not already defined.
1854 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
1856 * README: Update for release 3.95.
1857 * config.gdb: Don't create readline dir in subdir builds.
1858 * main.c: Include with "..." form for non-system include files,
1859 so "gcc -MM" for "make depend" works.
1860 Include readline files with "...h" rather than <readline/...h>.
1861 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
1863 * coffread.c: Undo minor damage done by Rich Pixley. Use
1864 different internal and external representations of COFF
1865 data structures. Use new BFD routines for swapping them in and
1867 * symfile.c (free_named_symtabs): Avoid freeing file names that
1868 are null or empty. Old i960 tools seem to produce files that
1869 claim to have empty names, causing each successive file read
1870 to blow away the previous one.
1871 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
1872 Move deferred_stores to top of file, but don't separate its
1873 #define's from its variable. Add commentary.
1874 * Makefile.dist: Fix Rich damage; undo "configure" changes in
1875 favor of keeping the (working) config.gdb. Move readline
1878 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
1880 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
1882 * infptrace.c (fetch_registers): no result, since now void.
1883 * tconfig/news: target depends on m68k-tdep too.
1885 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1887 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
1890 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
1891 applied various small fixes due to or inspired by RMS comments
1893 * doc/gdb.texinfo: finished using all RMS comments, save those for
1894 appendices on readline and cmd history (which are in other source
1897 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1899 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
1900 chapter 9; (2) documented 'break' command's menu mode for
1901 overloaded names, in response to hgs problem report C++ p-31
1903 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1905 * doc/gdb.texinfo: (1) better introductory example; (2) more
1906 consistent use of @code, @samp, @file, @kbd throughout; small
1907 cleanups to first three nodes; (3) new "Contributors" node;
1908 (4) Appendix, Renamed Commands; (5) divert specialized startup
1909 instructions to "Targets" chapter for generic manuals, while
1910 leaving them up front for manuals specific to specialized
1911 environments; (6) apply fixes from RMS comments through chapter 4.
1913 * pretex.m4: modify explanatory text slightly (and redefine
1914 "regexp") to keep GNU m4 from complaining. (It still crashes
1915 later, but one step at a time...)
1917 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
1919 * readline/readline.c (update_line): Avoid dereferencing a pointer
1920 before comparing it to its bounds. Saber caught this.
1921 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
1922 and only set PC if tgetstr returned non-null. Saber caught this.
1924 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1926 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
1927 stuff for config manual) here where it counts; updated
1928 to use new subdir structure (gdb/doc/).
1930 * Makefile: generated from above via
1934 * gdbint.texinfo: added instructions on generating gdb.info* files
1935 locally for release. These are ordinary info
1936 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
1937 Makefile)---but due to use of texinfo 2, can't count on makeinfo
1938 to generate these, so we distribute them already formatted.
1940 * gdb.texinfo: included full Info node and menu crud (as generated
1941 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
1943 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
1944 put in comments-for-future gdb.info target (one day makeinfo will
1947 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1949 * gdb.texinfo: Updated to include new or old undocumented
1950 commands, at least the following (perhaps some others I forgot to
1951 record): info f, info float, info path, info program, info s, info
1952 set, info source, info terminal, info types, info user, set/show
1954 Also covered all recent GDB command renames for v4.
1956 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1958 * mipsread.c: Rather than keeping count of how many symtabs
1959 and psymtabs we have, for sorting purposes, count them when
1960 we need to sort. This fixes bug in rereading of symbol tables.
1962 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1964 * infcmd.c: renamed "info path" to "show paths"
1965 * gdbrc.tex: documented above.
1967 Wed May 8 04:51:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1969 * remote.c: Fix comments.
1970 * utils.c (error): Force out any pending wrap output.
1972 Sat May 4 11:11:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1974 * Makefile.dist: Roll VERSION to 3.95.
1975 Fix up "saber_gdb" to work again.
1976 * saber.suppress: Update.
1978 * coffread.c, exec.c, infptrace.c, inftarg.c, remote.c, solib.c,
1979 symtab.h, target.c, target.h: Lint.
1980 * core.c: setup and select frame after reading shared libs,
1981 else reading shared libs will clobber them. Lint.
1982 * utils.c (error): Force out any buffered wrap text.
1984 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)

2455 * mipsread.c [!CMUCS]: #include <syms.h>.
2457 * mips-xdep.c (fetch_core_registers): #if 0 out the whole function.
2459 * Move read_memory_nobpt from mem-break.c to breakpoint.c.

2463 * utils.c (_initialize_utils): Rename "set demangle" to
2464 "set print demangle", "set asm-demangle" to "set print
2465 asm-demangle" and "set sevenbit-strings" to "set print

2484 Rename "set addressprint" to "set print address".
2485 Rename "set arrayprint" to "set print array".
2486 Rename "set array-max" to "set print elements".
2487 Rename "set prettyprint" to "set print pretty".

2497 Sun Apr 14 23:08:34 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
2499 * inftarg.c (child_open), remote-vx{,.68}.c (vx_proc_open):
2500 New function to give correct error message.
2502 Thu Apr 11 17:19:41 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
2504 * target.h: Add to_doc and target_preopen.
2505 target.c: Add target_preopen and target_command.
2507 (add_target): Call add_cmd and mess with targetlist->doc.
2508 core.c, exec.c, remote-eb.c, remote-nindy.c, remote-vx.c,
2509 remote-vx.68.c, inftarg.c, remote.c: Add doc field to target struct.
2510 Call target_preopen from open routine.
2512 * main.c: Rename editing_info to show_commands.
2513 (_initialize_main): Rename "info editing" to "show commands".
2515 * source.c: Rename directories_info to show_directories.
2516 (_initialize_values): Rename "info directories" to "show directories".

2525 * symfile.c: Rename add_syms_command to add_symbol_file_command.
2526 (_initialize_symfile, add_syms_addr_command):
2527 Rename add-syms to add-symbol-file.
2529 Thu Apr 18 18:08:30 1991 John Gilmore (gnu at cygint.cygnus.com)
2531 * symfile.h (free_named_symtabs): Rename from free_named_symtab.
2532 * symfile.c (clear_symtab_users_once, cashier_psymtab,
2533 free_named_symtabs): Move these routines from symmisc.c.
2534 * symmisc.c (same): same.
2535 (free_symtab): Make non-static.
2536 * symtab.h (free_symtab): Declare as exported void fn now.
2537 * dbxread.c (end_symtab, end_psymtab): Change comments.
2538 (initialize_dbxread): Call dbx_new_init() in case the first
2539 command is add-symbols.
2540 * target.c (dummy_target): Permit add_syms_addr_command.
2542 Sat Apr 13 14:46:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2544 Permit symbols to be superseded when new symbol files have
2545 been read in, particularly for VxWorks.
2547 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
2548 to the main file, as well as to include files. Also, put global
2549 functions into the global psymtab, to make "i fun" work.
2550 (end_psymtab): Free named symtabs and psymtabs for a file, once a
2551 new psymtab for it has been read.
2552 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
2553 a file, once a new symtab has been read for it.
2554 * mipsread.c: FIXME. We need to do the same for MIPS, but it
2555 looks harder to determine the top-level block before it's been
2556 queued to the psymtab list.
2558 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
2559 If we have wiped out any old symbol tables, clean up at end of
2561 (symbol_file_command): Don't reference symfile_fns if it's zero.
2563 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
2564 defines for the blocks of a blockvector that contain global and
2565 file-static symbols and the first of the smaller scope contours.
2566 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
2567 decode_line_1, make_symbol_completion_list): Use the above.
2568 * coffread.c (end_symtab, patch_opaque_types): Ditto.
2569 * dbxread.c (end_symtab): Ditto.
2570 * expread.y (block): Ditto.
2571 * mipsread.c (throughout): Ditto.
2572 * symmisc.c (free_named_symtabs): Ditto.
2574 * symtab.c (list_symbols): Process the first symbol of the
2575 static psymbols list.
2576 (types_info): Restore this function from its untimely #if 0.
2577 It's not perfect, but it is better than nothing.
2578 (_initialize_symtab): Restore "info types".
2580 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2582 * m68k-stub.c: Remote stub for 680x0's, created from
2583 rem-m68k.shar (which is removed).
2584 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
2585 Remove RCS log stuff now that we use CVS and it blows our diffs.
2587 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2589 * symmisc.c (free_named_symtab): Make it work, in its current
2590 kludgy fashion. Change result to indicate if we blew away bkpts.
2591 * dbxread.c (end_symtab): Accumulate result from
2592 free_named_symtab and print warning if we blew user's state.
2593 * symfile.h: free_named_symtab now returns an int.
2595 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
2597 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
2598 is the first symbol read, even if not mainline.
2599 (dbx_psymtab_to_symtab): symfile might be zero, cope.
2600 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
2601 (set_section_command): New command ("section xxx yyy" -- should
2602 be renamed to "set section xxx yyy" FIXME) which sets the
2603 base address of a section of the exec file, overriding the
2604 virtual address that BFD reports.
2606 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2608 * exec.c: Add add_syms_addr_command to exec_ops, so you can
2609 load symbols at any address while examining an exec file.
2611 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
2613 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
2614 for printing the float info is host-dependent, not
2615 target-dependent. FIXME.
2616 * i386-pinsn.c: Move #includes to top, remove useless ones.
2617 * i386-tdep.c: Don't bother including <.../reg.h> since we
2618 don't use it (and it doesn't exist on host systems).
2620 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
2621 Convert negative numbers properly.
2622 (ieee_test): Make numbers really random; fix format arg.
2624 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
2625 * core.c (core_detach): Unpush core_ops, which might not be on
2626 top. We used to just pop the top, which broke things. Don't
2627 need dont_repeat() any more.
2628 (core_file_command): Psst! Don't repeat it.
2629 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
2630 * expprint.c (print_subexp): Avoid switch fallthru on
2631 BINOP_ASSIGN_MODIFY, so we can print += and such.
2632 * frame.h: Fix typo.
2633 * inflow.c (kill_command): After killing inferior, print our
2634 current frame in the core file, if we have one.
2635 (generic_mourn_inferior): When inferior dies, either select
2636 the current frame (in the new target, e.g. core file), or
2637 set both the current and selected frames to NULL.
2639 Changes from Peter Schauer.
2641 * infptrace.c: Avoid <sys/ptrace.h> on USG.
2643 * Make all file names fit in 14 characters (sigh and damn!):
2644 mv hp300hpux-xdep.c hp300ux-xdep.c
2645 mv symmetry-xdep.c symm-xdep.c
2646 mv symmetry-tdep.c symm-tdep.c
2647 mv convex-opcode.h convx-opcode.h
2648 mv tm-vxworks960.h tm-vx960.h
2649 mv tm-vxworks68.h tm-vx68.h
2650 mv Makefile.srcdir Makefile.sdir
2651 mv gdb-int.texinfo gdbint.texinfo
2652 mv remote-sa.m68k.shar rem-m68k.shar
2653 mv remote-multi.shar rem-multi.shar
2654 * Makefile.dist, README, config.gdb, convex-pinsn.c,
2655 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
2656 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
2659 * command.c (user_info_1, user_info): New command for listing
2660 the user-defined commands.
2662 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
2664 * dbxread.c (really_free_pendings): Clear file_symbols
2665 and global_symbols after freeing them; otherwise, running
2666 this function twice (if it appears twice on the cleanup
2667 chain), we try to free things twice.
2669 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
2670 based on text_addr (the address of text in core), not on addr (the
2671 offset between text in the .o file and in core). This change
2672 is from Peter Schauer.
2674 * main.c: Define ALL_CLEANUPS as a cast of zero.
2675 (return_to_top_level): Use it.
2676 (main): Do all cleanups after each command run as part
2677 of the gdb startup sequence. Also do all cleanups before
2678 entering the command loop, and every time we exit the command
2679 loop and reenter. Before, the cleanups from the startup sequence
2680 were being left undone until the first error!
2681 (command_loop): Rename do_nothing cleanup to command_loop_marker
2682 so we can see it easily when examining the cleanup chain.
2683 (init_signals): Add another do_nothing for signal handling.
2684 (quit_command): Only try to kill target if it has execution.
2685 Problems in the target stack got us into a state where
2686 inferior_pid was nonzero but none of the targets had execution.
2687 In this state you couldn't exit gdb.
2689 * dbxread.c: Two changes from Peter Schauer.
2690 (echo_command): Fflush output after an echo command.
2691 (show_history): Pass all args to cmd_show_list.
2693 * utils.c (init_malloc): Call mtrace to turn on tracing
2694 if the environment variable MALLOC_TRACE is set to a file name.
2695 * mtrace.c: Add source file which provides a log of every malloc,
2696 free, and realloc to a trace file.
2697 * mtrace.awk: Add source file which analyzes the trace file.
2698 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
2699 (VERSION): Roll to 3.94.3.
2701 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
2702 (check_duplicates): Don't bother with watchpoints.
2703 (set_raw_breakpoint): Comment about danger of this routine.
2704 (watch_command): Parse and eval all args before calling
2707 * solib.c (find_solib): Avoid error in referencing memory to
2708 see if any more shared libraries have been added. This is
2709 particularly useful if the target has terminated. Bug reported
2712 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
2713 in bringing up 3.94.2 on the Sun-3.
2715 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
2716 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
2717 expression (in scope) before reenabling watchpoint.
2718 * signame.c (init_sigs): Add missing declaration of i, fix
2719 sys_siglist declaration.
2720 * source.c (list_command): Fixed range computation to use
2722 * stack.c (backtrace_command): Do not allow command if target has
2723 no stack, print informative error message.
2724 * target.c (target_command): Do not write into command line
2725 because this fails if the target command is used in a user defined
2726 command. [This change was enhanced by gnu to support any-
2727 unique-prefix matching on target names.]
2728 * valops.c (value_struct_elt): Avoid infinite loop on an
2729 erroneous attempt to print the member of function (try p main.p).
2731 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
2733 * expread.y (name_no_typename): Avoid reduce/reduce errors
2734 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
2735 Since the GDB parser really doesn't use name_no_typename in a
2736 name-only context, the parser can't tell the diff between
2737 names and numbers here. Avoid allowing a name_no_typename
2738 to be a NAME_OR_*INT to resolve the conflict.
2740 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2742 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
2744 * valprint.c (val_print_fields): bitfield printing didn't handle
2745 byte order. Indirect through a few more fns to cope.
2747 * values.c (modify_field): also cope with byte order.
2749 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2751 Cleanup for release 3.94.2:
2753 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
2754 include files. Roll version to 3.94.2.
2756 * coffread.c (init_stringtab): Read length into unsigned char
2757 array before swapping; don't assume 32-bit longs.
2759 * target.c (target_info): Don't bother with get_sym_file, just use
2760 the symfile global variable.
2761 * symtab.h, symfile.c (get_sym_file): Delete it.
2763 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
2764 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
2765 (read_type): Replace one more error() with complain().
2767 * mipsread.c (parse_partial_symbols): Replace printf with complain.
2769 * i960-tdep.c: Fix copyright attribution.
2771 * config.gdb: Quote all backquotes in doublequotes. You can
2772 quote me on that. BSD 4.4 shell found this one.
2774 * infptrace.c (throughout): The third argument to ptrace is an
2777 * infrun.c (wait_for_inferior): When program has terminated, we
2778 have to call target_terminal_ours before we pop that target off
2779 the stack (e.g. before a call to target_kill or
2780 target_mourn_inferior). This fixes problem where a program
2781 terminates, then GDB stops for (tty output) and you have to type
2782 "fg" to the shell to resume it. FIXME: This code for what to
2783 do after termination really should be in normal_stop instead.
2785 * gdbcore.h (read_memory_check): Change declaration; it changed
2788 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
2789 4.4 prereleases, this avoids a bug in their sgtty compatability
2791 * remote.c: Use terminal.h rather than hand-rolling the same.
2793 * signame.c, signame.h (psignal): Arg is unsigned, not int.
2794 * utils.c (strsave, strstr): Fix arg types.
2795 * valprint.c (val_print): lint
2797 MIPS symbol table support from Per Bothner:
2799 * symfile.c (symtab_fns): Remove initializer table that needs to
2800 be hacked for each new symbol file format supported.
2801 (add_symtab_fns): New function, chains symbol table
2802 handlers into the global list.
2803 (symfile_init): Search this list.
2804 * symfile.h: Add next pointer, declare add_symtab_fns.
2805 * coffread.c (_initialize_coffread): Call add_symtab_fns.
2806 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
2808 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
2809 symbol *). Thus, we no longer need the hack to trash
2810 pst->filename. Good, since that hack confused code in symfile.c!
2812 (reorder_symtabs, destroy_all_symtabs): Removed static
2813 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
2814 Instead, the latter now uses a temporary array (stack-allocated
2815 from an obstack, and then freed).
2817 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
2818 haven't been set in the outermost stBlock of a procedure. This was
2819 a problem with f77 binaries on Ultrix 4.?.
2821 (new_symtab, new_symbol, new_type): Continue changing code to use
2822 obstacks more and otherwise conform to dbxread internal style.
2823 Made the free_code of symtabs be free_linetable (as in dbxread)
2824 instead of free_contents. This implies memory leaks when reading
2825 a new symbol table, until the conversion is finished. Did change
2826 (struct symbol) and (struct type) to be allocated on the
2827 symbol_obstack. Blocks and blockvectors are among the things
2830 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
2831 tested much, but it solved one problem (reported by Meissner), and
2832 cleans up some other things. The problem happened when an
2833 included file contains actual code (functions) and not just
2834 definitions. The mips coff is a little inconvenient there, since
2835 it may cause a procedure to be mapped to the wrong psymtab.
2837 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
2838 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
2839 this will need work for the new core paradigm.
2841 Opcode patches from the net:
2843 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
2844 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
2845 missing altogether - they are added here. From Bruce Bauman.
2846 * mips-opcode.h: The low mask for C0 instructions was too small.
2847 From Garrett Lau. I modified the fix to check the entire 32-bit
2850 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
2853 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2855 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
2857 * dbxread.c (read_type): Pointer subtraction (value_sub in
2858 valarith.c) sometimes failed because the types of the
2859 pointers being subtracted were not identical.
2860 These differed because dbxread.c was allocating pointer types
2861 using dbx_alloc_type+smash_to_pointer_type instead of
2862 lookup_pointer_type. I failed to find a justification for the
2863 former, so I changed it to use the latter. Similarly, I
2864 replaced smash_to_function_type by lookup_function_type,
2865 and smash_to_reference_type by lookup_reference_type.
2867 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
2868 _initialize_mipsread): corresponding changes.
2870 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
2872 * source.c (mod_path): Do tilde_expand on each component of the path,
2873 rather than on the (list of) paths as a whole.
2874 (print_source_lines): Set first_line_listed in addition to
2875 current_source_symtab and current_source_line. If the source was
2876 not findable, after a "dir" command to fix the problem,
2877 a "list" would get the wrong lines.
2879 While I was there... (gnu):
2881 * dbxread.c (read_type): Change error to complaint.
2883 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2885 First attempt at detailed understanding of symbol table memory alloc.
2887 * dbxread.c (dbx_symfile_read): Free our string table if we
2888 aren't the mainline. Free the "info" struct since we're done with
2890 (init_psymbol_list): Free any previously allocated psymbol lists.
2891 (): FIXME: Should realloc-down the psymbol lists when done reading
2892 the main symbol file?
2894 * symmisc.c (free_symtab): Free fullname field too.
2896 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
2897 (REGISTER_ADDR): Make result type unsigned int.
2899 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
2900 define REGEX must also define REGEX1 (its dependency).
2902 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
2904 * tconfig/i960: No longer works, points you at vxworks960 or
2907 * xgdb.c, XGDB-README: Remove file. Users can get the much
2909 * Makefile.dist: Remove all trace of xgdb.
2911 * breakpoint.c (breakpoint_1): Pass demangle arg to
2912 print_address_symbolic.
2913 (clear_breakpoints): Remove unused function.
2914 (breakpoint_re_set_one): Guts of breakpoint_re_set.
2915 (breakpoint_re_set): Use catch_errors to do them all anyway.
2917 * gdb-int.texinfo (Host versus Target): Add section on what is
2918 a "host" feature versus what is a "target" feature.
2920 * infcmd.c (path_command, path_info): Handle the PATH variable
2921 (object search path) as conveniently as the source search path.
2922 * environ.c (set_in_environ): Set some vars in GDB's environment,
2923 in addition to the child's. PATH, G960BASE, G960BIN for starters.
2924 * source.c (mod_path): New function, from guts of
2925 directory_command, modifies a path. Used by path_command.
2926 (directory_command): Call it.
2927 * defs.h (strsave): Declare.
2929 * utils.c (sevenbit_strings): Add new printing option.
2930 (printchar): Use it.
2931 (strsave): Provide this handy helper routine.
2932 (set_width_command): Rename set_screen_width_command.
2933 (_initialize_utils): "set screen-width" => "set width";
2934 "set screen-height" => "set height"; add sevenbit-strings.
2936 * infcmd.c (do_registers_info): Print floating point registers
2937 in raw hex as well as float format, regardless of whether it is
2938 a "virtual" convertible register.
2939 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
2940 regs as a double, just in case it's being used that way.
2941 * values.c (unpack_long): Comment on array/function coercion.
2942 (unpack_double): Argument is in target byte order now. For
2943 integer arguments, just call unpack_long and float the result.
2944 * m68k-tdep.c: include defs.h for "const" handling.
2945 * remote-nindy.c: Use ieee-float stuff.
2946 (nindy_fetch_registers): Unpack double regs to host double, then
2948 (nindy_store_registers): Pack extendeds to host double, flip
2949 around by misusing unpack_double, send as target double.
2951 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
2952 zero, as when stopped at the first instruction of a process.
2954 * blockframe.c: Fix filename in comment (param.h => tm.h).

2956 * tm-68k.h: Fix typos.
2958 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
2960 Changes from a bringup on the DEC Vax under Ultrix 4.0.
2962 * coredep.c (fetch_core_registers): Pass end-address of register
2963 section to register_addr as expected. Don't call supply_register
2964 if we'd just pass it garbage.
2966 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
2968 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.

2974 even if we can't print it.
2976 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
2978 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
2980 Clean up IEEE floating point support.

2992 * m68k-tdep.c: Define ext_format_68881.
2993 * sparc-tdep.c: Define ext_format_sparc, though unused.
2994 * Makefile.dist (HFILES): Add ieee-float.h.

3001 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
3002 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
3003 * tconfig/nindy960: Remove reference to coffstrip.o.
3005 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
3007 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3009 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
3010 * dbxread.c: Remove static symfile_bfd.
3011 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
3013 * inftarg.c (child_detach): Pop the child_ops vector if the
3014 detach is successful.
3015 * remote-nindy.c (nindy_create_inferior): Don't push a new
3016 nindy_ops since nindy uses the same one for execution and memory
3018 * core.c (core_ops): Use child_attach and child_create_inferior
3019 rather than default attach and create_inferior functions.
3021 Handle floating point registers in core files.
3023 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
3024 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
3025 This version untested since BFD doesn't yet support sun3 core
3027 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
3028 conventions. Fix comments and style. This version has not
3029 been compiled yet, since we have no HP inhouse.
3030 * core.c (get_core_registers): Look for two sections, ".reg"
3031 and ".reg2", and pass both to fetch_core_registers sequentially.
3033 Revise directory path yet again.
3035 * source.c (forget_cached_source_info): Not static any more.
3036 (init_source_path): New default source path is "$cdir:$cwd".
3037 (dir_command): Handle variable arguments ($cdir, $cwd).
3038 (source_info): Print "Compilation directory" rather than
3039 "Originally compiled in" to remind people of $cdir.
3040 (openp): If the path contains $cwd, use current directory.
3041 (open_source_file): If compilation directory is known, replace
3042 first $cdir in path with the compilation directory.
3043 (print_source_lines): Even if we can't print the lines, set the
3044 current symtab and line for future commands like "info source" or
3045 "breakpoint". Also, error message now contains the file name,
3046 line number, and file access error message.
3047 (_initialize_source): Fix help text to describe changes.
3048 * main.c (cd_command): Forget cached source info when we chdir.
3049 * utils.c (strstr): Add simple implementation.

3053 * coffread.c (read_one_sym, init_linetable, init_stringtab):
3054 Byte-swap COFF symbol tables if necessary when reading them in.
3055 Use complain() to replace error message in one spot. Needs
3056 corresponding change in bfd/coff-code.h to make some symbol
3057 swapping routines non-static.
3059 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3061 Merge changes from Eirik Fuller, for UTek.

3069 declarations of errno.
3071 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
3073 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
3074 <rpc/rpc.h> and <rpc/types.h>.
3076 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
3078 * i960-tdep.c (examine_prologue): Add new argument limit,
3079 which stops the scan at the end of the prologue, or at the PC.
3080 This fixes a problem where it walks down into the code for the
3081 user's statements if that code looks like function prologues.
3082 Mark Fox and I have been bouncing this code back and forth, making
3083 small changes to it. Callers changed to match.
3085 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
3087 Cleanup for gdb-3.94 release final:
3089 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
3090 the .c files from vx-share and nindy-share, from the various
3091 macros, since they are not found via ALLDEPFILES.
3092 (SFILES): Add tm-i960.h.
3093 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
3094 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
3096 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
3097 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.

3101 * am29k-tdep.c: Add contribution line.
3102 (examine_prologue): Cache information about function prologues in
3103 the misc-function-vector to avoid lots of references over the
3104 serial line while examining instructions.
3106 * core.c (core_close): New function made from cleanup_core.
3108 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
3109 remote-vx.c, remote.c, target.c, target.h,
3110 Update target_ops vector to add attach, close, and load entries.
3111 Use add_syms_addr_command, not add_file_addr_command, for
3112 add_file. Break out close routine from existing code.
3114 * dbxread.c (really_free_pendings): Don't free pending_blocks;
3115 they are in an obstack.
3116 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
3118 (define_symbol): Add symbol type parameter; change callers;
3119 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
3120 it to influence the symbol class on the i960.
3121 (define_symbol): Swap LOC_CONST's into target byte order.
3123 * exec.c (exec_close): New function.
3124 (exec_file_command): Call it.
3126 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
3127 Fix byte order of frame pointer.
3128 (read_var_value): Result of 0 if var's value can't be found,
3129 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
3130 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
3131 (locate_var_value): Use read_var_value and use its lazy address
3132 as the location of the var's value. Lint.
3134 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
3137 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
3138 obsolete Intel versions in favor of vxgdb versions.
3139 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
3140 code dealing with byte order of values, which Intel did in host byte
3141 order rather than gdb-4's target byte order.
3142 (i960_frame_chain_valid): Move to nindy-tdep.c.
3143 (examine_prologue, skip_prologue, frame_find_saved_regs,
3144 frame_args_address, leafproc_return, saved_pc_after_call,
3145 pop_frame): Add vxgdb versions from Mark Fox.
3146 (examine_prologue, frame_struct_result_address): Add code
3147 to deal with the saved value of G13 (struct return address
3149 (frame_args_address): Modify Mark's version to prefer the
3150 saved value over the current value in the topmost frame.
3151 Cache result in the frame info to avoid performance hair in
3153 (print_fault): Add gdb960 code for printing faults.
3154 (_initialize_i960): Actually call check_host.
3156 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
3157 add stub routines. FIXME, these currently just return zero!
3159 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
3160 (attach_command): Call target_attach, not target_open, now.
3162 * infrun.c (normal_stop): Make global, not static, for vx_attach.
3163 (child_attach): Rename from child_open.
3164 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
3165 don't confuse it with a zero step_resume_break_address.
3167 * inftarg.c (child_detach): Eliminate inferior_pid test.
3168 (child_files_info): Clean up message a bit.
3169 (child_ops): Use child_attach, not child_open, to attach.
3171 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
3172 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
3173 findvar.c to here, since it depends on the contents of the
3174 shadow_contents of breakpoints, but keep if #if 0 since it is
3177 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
3180 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
3181 (ptype_command, display_command): Eliminate have_inferior_p and
3182 have_core_file_p in favor of target_has_stack or
3183 target_has_execution.
3184 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
3185 code for actually finding the values of arguments, though we still
3186 keep track of the maximum stack offset for use in printing unnamed
3187 arguments. Handle missing FRAME_ARGS_ADDRESS.
3189 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
3190 (struct nindy_regs): Define registers passed to/from nindy.
3191 (nindy_fetch_registers, nindy_store-registers): Translate between
3192 nindy and GDB formats for the registers.
3193 (dcache_init): Statically allocate the cache, since it was being
3194 allocated by a malloc that was never freed anyway.
3195 (nindy_create_inferior): Error, not core dump, if no exec file.
3196 (nindy_before_main_loop): Use target_load, not target_add_file.
3198 * remote-vx.c (net_load): Specify large timeout for load
3199 requests. Allow user to break out with INTERRUPT.
3200 (net_break): Remove useless code, clean up. Change callers.
3201 (parse-args, skip_white_space, find_white_space): Clean up arg
3202 parsing to cope with quoted strings.
3203 (net_wait, net_quit): Never call error, just return status.
3204 (vx_read_register, vx_write_register): Cleanup status checking.
3205 #ifdef the code based on which CPU we are using (960 or 68k),
3206 FIXME, this should be completely general but it isn't yet.
3207 (vx_xfer_memory, vx_resume): Cleanup status checking.
3208 (vx_run_files_info): Improve message.
3209 (vx_load_command): Renamed from vx_add_file_command. Allow load
3211 (net_ptrace): Remove unused routine.
3212 (vx_wait): Adopt code from vxgdb960 to cope with broken
3213 connections to target machine and prompt to disconnect. Remove
3214 debug printouts. Map some EVENT_'s to SIGnals.
3215 (add_symbol_stub, vx_open): Print names of object files we found,
3216 and "ok" if we read their symbols OK. Clarify output in general.
3217 (vx_attach, vx_detach, vx_kill): Add these commands.
3218 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
3219 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
3220 "info files" output, and create_inferior, since we already have
3223 * stack.c (frame_info): Replace Frame_unknown with 0.
3224 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
3225 (return_command): Pop until the PC matches as well as the FP,
3226 so it works even if the FP is shared with another function,
3227 as in "frameless" or "leaf" procedures.
3229 * symfile.c (load_command): renamed from add_file_target_command.
3230 (add_syms_addr_command): renamed from add_file_addr_command.
3231 (add_syms_command): Stub to call target_add_syms.
3232 (_initialize_symfile): Change command names and descriptions,
3233 add-file => add-syms, and load from alias to its own command.
3235 * target.c (kill_or_be_killed, maybe_kill_then_attach,
3236 maybe_kill_then_create_inferior): Default for attempts to start
3237 a process, if one is already running, is to ask about killing
3238 it and retry if yes.
3239 (upstack_create_inferior): #if-0 it, strata obsolete it.
3240 (push_target, unpush_target, pop_target): to_close() a target
3241 before unstacking it.
3242 (target_info): Renamed from target_files_info.
3243 (_initialize_targets): Rename "i files" as "i target", accessible
3246 * target.h: Improve comments about the target_ vectored routines.
3248 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
3249 Convert commenting style to standard GNU style.
3250 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
3251 (SKIP_PROLOGUE): No longer a no-op.
3252 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
3253 (*_REGNUM): Sort register numbers.
3254 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
3255 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
3256 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
3257 are now 10 byte extendeds, not 8 byte doubles.
3258 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
3259 for nindy versus vxworks targets. FIXME, this should possibly go
3260 in the target vector.
3261 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
3262 frame_saved_regs and arg pointer with each frame.
3263 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
3264 (FRAME_ARGS_ADDRESS): Use cached result.
3265 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
3266 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
3267 (PRINT_RAMDON_SIGNAL): Call print_fault.
3268 (POP_FRAME): Now works.
3270 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
3271 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
3272 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
3273 (ADDITIONAL_OPTION_HANDLER): use target_load, not
3276 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
3277 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
3279 * valarith.c (value_subscripted_rvalue): Avoid handling
3280 floats and doubles specially; it gave alignment errors. Lint.
3282 * valops.c (value_of_variable, value_of_this): Error if unknown
3285 * valprint.c (print_floating): Bcopy rather than pointer-deref,
3286 to avoid alignment problems.
3287 (value_print): Handle unknown value address.
3288 (cplus_val_print): Two args are ignored; remove them. Change caller.
3289 (val_print): Use unpack_long rather than pointer-deref.
3292 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
3293 to avoid alignment problems.
3294 (value_being_returned): Error if return value unknown.
3295 (set_return_value): Add bogosity warning, FIXME. *
3297 * TODO: A woman's work is never done.
3299 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
3300 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
3301 Add ieee-float.o to OBS.
3302 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
3303 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
3304 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
3306 Changes to generalize the VxWorks RPC protocol slightly, to handle
3307 i960 as well as 68000.
3309 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
3310 * vx-share/reg.h: Produce i960 regs #ifdef I80960
3311 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
3312 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
3313 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
3314 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
3315 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
3316 so they will move in target byte order rather than network
3317 byte order (happens to be the same).
3319 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
3321 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
3323 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
3326 Add contribution lines to various files, showing where they
3329 * breakpoint.c (break_insn, check_break_insn_size,
3330 read_memory_nobpt): Remove to mem-break.c.
3332 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
3335 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
3336 entry has bad register number. This change is not
3337 tested in this release, FIXME.
3339 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
3342 * value.h: Force value's contents field to be aligned to hold
3343 at least a double or a long long (if supported). This avoids
3344 doing bcopy's in and out of the contents field.
3346 (step_1): Avoid coredump under obscure circumstances when we
3349 * symtab.h (misc_info): Add field to misc function vector for
3350 any kind of cached information the target code desires. AMD
3351 29000 uses this to avoid repeating examine_function_prologue's.
3353 * coffread.c: Lint. Remove static symfile, read_section_header.
3354 core.c (have_core_file_p): Lint: remove.
3355 expprint.c (print_subexp): Lint.
3356 infptrace.c, valops.c, valprint.c: lint.
3358 Roll in changes from vxgdb-5.0.1:
3360 * symtab.h: Comment byte order of each address class. Add
3361 LOC_LOCAL_ARG for frame-relative args (960).
3362 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
3363 symtab.c, symmisc.c: ditto.
3365 * infrun.c (init_wait_for_inferior): Clear stop_signal.
3367 * remote.c (remote_resume): Error if resume with a signal.
3369 * symfile.c (prim_record_misc_function): Clear misc_info.
3370 (fill_in_vptr_fieldno): Check stub type of arg.
3372 * valops.c (value_cast): Avoid looking up names of types whose
3373 name we don't know, to prevent coredump. Sun CC produces typedef
3374 rtx and the name of *rtx is zero...
3376 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3378 Roll in changes from final AMD 29000 port (Tiemann).
3380 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
3381 for ../include/a.out.encap.h. This might not work now that BFD
3382 is separately compiled. Instead, BFD support for encap will have
3383 to translate machine type 29k into the right COFF_MAGIC.
3385 * infcmd.c: Remove references to inferior_pid that aren't used
3386 in actual ptrace calls; use target_has_execution, etc.
3387 (have_inferior_p): Remove function.
3388 (program_info): Print target info rather than "process number";
3389 avoid gratuitous messages unless from_tty.
3390 (run_stack_dummy, finish_command): Set proceed_to_finish.
3391 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
3392 main.c: Lint. Lose have_inferior_p().
3393 inferior.h (have_inferior_p): Remove, lint.
3394 (proceed_to_finish): Add flag to ask that all regs be saved
3395 by normal_stop, for the few commands that need it, speeding up
3396 serial I/O. Add comments to stop_registers.
3398 * remote-eb.c: Remove newline from breakpoint message we grep
3399 for. Never time out when running the user program.
3403 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3405 Roll in changes from vxgdb-5.0.1:
3407 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
3408 symbol in its raw form, we are processing an unlinked ".o" file.
3409 See if the target environment has assigned it an address, using
3410 target_lookup_symbol (VxWorks does), and enter it into the symtab
3413 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
3414 68k versions for a simpler version that assumes zero FP at bottom.
3415 Fixes bug of truncated stack reports.
3417 * target.h (target_lookup_symbol): Define this routine's args
3418 and result, finally.
3420 * target.c (nosymbol): Default routine for target_lookup_symbol.
3421 (target_default): Default lookup_symbol and call_function too.
3422 (files_info): Only print has_all_memory warning if a non-dummy
3425 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
3426 vx_convert_from_virtual): If target does not have floating point,
3427 zero register "values", and avoid doing cross-net conversions.
3428 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
3429 (vx_open): Rearrange code that attaches to target and reads
3430 symbols for all loaded modules, to work if some of the modules
3431 are not accessible. Add symbol_stub() and add_symbol_stub()
3432 as callbacks from catch_errors(). Allow connect attempt to be
3433 interrupted painlessly with ^C (FIXME, there are still some bugs
3434 if the interrupt happens during symbol reading.). Print
3435 final message with puts_filtered, since symbol messages are
3440 * main.c (catch_errors): Only print errstring if non-null.
3441 (command_loop): Avoid an ioctl per command to test ISATTY.
3443 * remote-vx.c (net_load): make static; avoid sophomoric msg.
3444 (vx_xfer_memory): Return correct result!
3445 (vx_files_info): Indicate whether target has float or not.
3446 (vx_lookup_symbol): Complain, not error, if target gone.
3447 (vx_open): Print "Connected" msg before disabling immediate-quit.
3448 [FIXME: lookup_symbol and vx_open changes need testing.]
3450 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
3451 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
3452 contributor lines and update copyrights to 1991.
3454 Changes from an attempted H-PUX host port:
3456 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
3457 defines PT_ATTACH and PT_DETACH but not PT_KILL.
3458 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
3459 * remote-vx.c: include <sys/time.h> for HPUX.
3460 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
3461 "core_file_command" routine to BFD regime. May not work yet.
3463 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
3465 * xgdb.c: Replace X10 version with some VJ version.
3466 (FIXME: Its copyright assignment is not on record.)
3467 * xgdb.c: Update include files to X11R4 (Xaw crud).
3468 (xgdb_display_source, create_text_widget): fix call to
3469 get_filename_and_charpos. Rewack source window stuff for X11R4
3470 (gleaned from include files, and "nm's" of binary libraries, since
3471 I had no doc available).
3472 (append_selection, append_selection_word): Disable with FIXME
3473 since R4 changed interface here.
3474 (create_buttons): Add back the old set of buttons.
3475 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
3477 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
3478 Roll VERSION to 3.94 (not yet final though).
3480 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3482 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
3483 obstack_int_grow, obstack_int_grow_fast): Eliminate
3484 cast on left of assignment, which gives MIPS cc fits and is
3487 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
3488 F_ALIAS. Use printf, not fprintf, when not passing a file
3490 (compare_opcodes): Check that identical instructions have
3491 identical opcodes, complain otherwise.
3493 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
3494 was reported by Roland McGrath.
3495 (unimp): Only match if exactly zero instruction. (Roland)
3496 (branches and traps): Generate all variations of these
3497 instructions with macros, based on a single call that defines
3498 each condition name and its binary representation.
3499 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
3501 * valprint.c (val_print_fields): Take, and use, format parameter.
3502 This means that "p/x struct" again prints the elements in the
3503 desired format. Changed callers.
3505 * stack.c (frame_info): Use filtered output, and indicate wrap
3506 points. Remove kludgy formatting designed to avoid line wrap.
3508 * utils.c (wrap_here): If the line is already full (because
3509 we had printed a long indent or long wrapped string), do an
3510 immediate newline-and-indent.
3512 * m68k-pinsn.c (print_insn_arg): Bugfix from
3513 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
3514 instruction is incorrectly disassembled as bkpt #8.
3516 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
3517 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
3518 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
3519 and then will dump core (sometimes). I traced it back to an
3520 uninitialized symfile_name in psymtab_to_symtab.
3521 (const_vol_complaint): Add quotes to message.
3522 (define_symbol): Only believe line number if gcc_compiled.
3523 Avoid allocating symbol if we will not return it.
3525 Add target strata support so that newly established targets go
3526 into their right place in the target stack (e.g. a new exec file
3527 doesn't wipe out the ability to access the running process).
3529 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
3530 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
3531 and initialize it properly in all the targets.
3533 * target.h: Document strata. Change return type of push_target.
3535 * target.c (nomemory): new function for dummy memory access.
3536 (tcomplain): Rename complain, now also used in symfile.c.
3537 (push_target): Push targets within strata. New return value shows
3538 whether new target is on top of stack or not. Always keep dummy
3540 (target_files_info): Ignore dummy target.
3542 * core.c (core_open): Warn user, and skip accessing file, if the
3543 core target is not the topmost target in the stack.
3544 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
3547 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
3548 target_ops, it doesn't belong there since we have no regs there.
3549 Change name of target from machine => memory to clarify.
3551 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
3553 * Freeze version 3.93 for release.
3555 * Makefile.dist: Handle vx-share and nindy-share subdirs
3556 properly when building gdb.tar.Z.
3558 * symtab.c: lint; add no_symtab_msg to consolidate the messages
3559 printed in various places, so I could change just one copy.
3561 * dbxread.c, coffread.c: Change references to bfd->iostream
3562 to cast to FILE *, now that BFD avoids needing types defined
3563 in other header files.
3565 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3567 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
3568 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
3569 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
3570 (actually gcc -Wall).
3572 * dbxread.c: Remove first_global_sym, last_global_sym, since
3573 they are never referenced.
3575 * defs.h (baud_rate): Declare.
3576 main.c: Define it, and add the -b option to set it.
3578 * gdb-int.texinfo: Add text on how to define a new host or target
3579 architecture, prompted by Per Bothner's questions about MIPS
3582 * gdb.texinfo: Document "complaints". Change doc of -q since
3583 gdb no longer prints the copyright and blurb if you specify a file
3584 name to be debugged (just like Emacs). Add doc for Nindy-specific
3585 command line flags for specifying target serial port and such.
3586 Update copyright to 1991.
3588 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
3589 has taken over for us the job of ripping up executable files. The
3590 crud caused Per Bothner's port to not compile.
3592 * infrun.c (normal_stop): Avoid printing "Program exited
3593 normally" if we are in batch mode. This allows a GDB which
3594 executes a program on a target system, to behave like a Unix
3595 command (input from stdin, output to stdout, no extraneous
3598 * main.c (main): Allow additional machine-dependent command line
3599 options to be specified with the ADDITIONAL_OPTIONS,
3600 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
3601 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
3602 processing to occur just before the main loop with
3603 BEFORE_MAIN_LOOP_HOOK.
3604 (main): If a "core file" argument is specified, and it is not a
3605 core file, try it as a process ID to attach.
3606 (symbol_completion_function): Attempt to cope with
3607 "show screen-" TAB, not very successfully. This needs more work,
3609 (batch_file): New function, returns whether we are reading
3610 commands from an interactive tty on stdin, or from somewhere else.
3611 Called by normal_stop since it doesn't get from_tty passed down
3612 to it like many commands do.
3614 * remote-nindy.c: Handle command line options for nindy
3616 (nindy_before_main_loop): Prompt user for tty name if they
3617 don't specify it before getting to the interactive command loop.
3619 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
3620 and -r command line options. Also add hook before main loop
3621 to make it easy to specify a tty.
3623 * TODO: More things to do, one done.
3625 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
3627 * dbxread.c: Make complaint() calls pass pointer, not struct.
3628 Add complaints about badly formatted C++ type information
3629 (const/volatile indicator, and parse errors resulting in
3630 error_type). Fix C++ virtual member fn comment.
3631 (read_struct_type): Avoid bumping pointer if we got a parse
3632 error; this prevents our walking beyond the end of a string.
3633 Terminate loop on null char as well as semicolon.
3634 (process_one_symbol): Fix the LBRAC fix so that it uses the
3635 last previous SLINE, FUN, or SO record's PC address. C++ debug
3636 symbols did not have SLINE records in a useful order compared
3637 to the LBRAC records.
3638 (define_symbol): Handle "catch" records.
3640 * symtab.c (check_stub_type): Added new complain
3641 `stub_noname_complain' and added a consistency check to
3642 keep the debugger from crashing when finishing from an
3643 exception frame. A real fix will be needed later.
3645 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
3647 * infcmd.c (attach_command): Make global.
3649 * Makefile.dist (REMOTE_OBS): Make these compile by default,
3650 but make them easy to comment out. Perhaps later they should
3651 be enabled by what CPU you configure for? FIXME.
3652 (VERSION): Roll to 3.93.
3653 (pinsn.o): Remove rule for obsolete file.
3654 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
3656 Run down a problem that manifested by printing the wrong function
3657 name in stack traces of read_ofile_symtab. Turned out that the
3658 problem was the SunOS 4.1.1 (and previous) C compiler outputs
3659 the LBRAC symbol with an address in the *data* segment, which
3660 blew our binary search through the blocks.
3662 * dbxread.c: Use the complain() facility consistently to bitch
3663 about problems in the symbol file we are reading.
3664 (finish_block): Add code to check the nesting of the blocks;
3665 complain and Procrust them to fit if wrong.
3666 (make_blockvector): Check the order of the blocks, complain
3667 [but don't cope] if wrong.
3668 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
3669 symbols to be sure their PC value is greater than the last SLINE
3670 (line number) symbol we've seen, complaining and adopting the
3671 SLINE PC value if wrong.
3673 * symfile.h (struct complaint, complaint_root, complain,
3674 clear_complaints): Add.
3675 * symfile.c (complain, complaint_root, clear_complaints): Add
3676 facility to deal with non-fatal complaints and to regularize their
3678 (symbol_file_add): Clear complaint counters to allow new complaints.
3679 (initialize_symfile): Add 'set complaints' and 'show complaints'.
3681 * dbxread.c (dbx_symfile_read): Remember the address and size
3682 of the string table for the main symbol file, so we won't read it
3684 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
3685 to avoid reading the string table yet again. Lint.
3686 (throughout): Improve filtered output, including word wrap.
3687 (read_range_type): Improve Bothner's fix to handle other types too.
3689 * utils.c: Improve line wrap implementation. Handle unlimited
3690 width by making chars_per_line unsigned.
3691 (puts_filtered): New, easy, function.
3693 * defs.h (puts_filtered): add.
3695 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
3696 call the identical sort_symtab_syms() in symfile.c instead.
3698 * expread.y: Suggest the `file' command rather than `symbol-file'.
3700 * command.h (enum var_types): Add zinteger for seroable
3702 * command.c (do_setshow_command): Handle var_zinteger. Restructure
3703 nested if's into a switch.
3705 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
3706 we did not stop because of a breakpoint (it must have been for
3707 some other reason, like a "stepi"), so don't print anything.
3709 * symtab.c: Include <sys/types.h> all the time. Now that BFD
3710 doesn't include <sys/types.h>, old SunOS's require it for
3713 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
3715 A test port of gdb-3.92.6 to the Sony NEWS.
3718 Don't normally link in remote- or vx stuff.
3719 Some of it doesn't compile, and it wastes space for 99% of the users.
3720 Remove reference to no-longer-used HAVE_VPRINTF.
3721 Fixed BFD_DEP typo to BFD_DIR.
3723 Fix cast in arg to bfd_h_getlong.
3724 Make char *prefix be const.
3725 Fix how certain range types are mapped into builtin unsigned int types.
3727 Remove 2 #includes. They cause errors (on Sony, at least),
3728 and aren't needed (they wern't in earlier versions).
3730 print_address_symbolic should never demangle labels
3731 (since it prints *assembler-level* labels).
3733 [This was superseded by the change to printcmd below.]
3736 Add some "volatile" return types to avoid warnings.
3737 If MISSING_VPRINTF add vprintf function and not just macro
3738 (since vprintf is used in printcmd.c).
3740 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
3741 (The latter isn't grokked by some PCC-based compilers.)
3743 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
3745 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
3746 * nindy-share/coffstrip.c
3747 Added some forward declarations (otherwise, gcc complains
3748 about implicit extern redefined as static).
3750 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
3752 Changes inspired by Per Bothner:
3753 * printcmd.c (print_address_symbolic): Take additional parameter
3754 specifying whether to demangle.
3755 (print_address): Pass in asm_demangle to control demangling.
3756 (print_address_demangle): New fn, takes explicit arg to control
3758 * utils.c: Add new vars demangle and asm_demangle, and let them
3760 (fputs_demangled): If !demangle, just print the argument.
3761 (fprint_symbol): If !demangle, just print raw symbol.
3762 * valprint.c (val_print): Call print_address_demangle rather than
3763 print_address, to cause demangling to depend on the global
3764 rather than assembler-level demangling setting.
3765 * WHATS.NEW, gdb.texinfo: Document.
3767 * main.c (show_command): Show all settings if no arg.
3768 (initialize_main): Make "info set" the same as naked "show".
3769 * command.c (cmd_show_list): Handle prefix commands in the
3770 list, and print the name of the setting as well as its English
3771 description and value.
3773 Allow gdb functions to specify where a line should wrap if it
3774 exceeds the size of a terminal line. Use it to make the output
3776 * utils.c (set_screen_width_command): New fn, mallocs a buffer
3777 of the right size when screen width changes.
3778 (set_screensize_command, screensize_info): Remove #if 0'd fns.
3779 (wrap_here): New fn, indicates a point in the output where we
3780 should wrap the line rather than just letting it overflow at a
3782 (fputs_filtered): Implement wrapping.
3783 (n_spaces): New fn, returns a pointer to N spaces.
3784 (print_spaces_filtered): Use n_spaces.
3785 * defs.h (n_spaces): Declare.
3786 * stack.c (print_frame_info): Wrap with 4-space indent after
3787 fn name and before filename and line number.
3788 * printcmd.c (print_frame_args): Wrap with 4-space indent
3789 before each argument name is printed.
3790 * valprint.c (value_print): Wrap with no indentation before
3792 (val_print_fields): Wrap with indentation relative to nesting
3793 level before each field name.
3794 (val_print): Wrap with nesting indentation before array elements.
3795 * command.c (do_setshow_command): Avoid extra newlines,
3796 wrap with 4-space indent around values printed, end with period.
3797 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
3799 * breakpoint.c (breakpoint_1): Implement addressprint for
3800 "info breakpoints" display. Change file name and line number
3801 format to " at file:nnn" rather than " (file line nnn)".
3802 * gdb.texinfo: Document.
3805 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3807 Frozen for gdb-3.92.6 release.
3809 README, WHATS.NEW: Update for 3.92.6 release.
3811 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
3812 coffread.o from configs since it is now built by default.
3813 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
3814 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
3815 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
3816 from configs since it is now built by default.
3818 Makefile.dist: Update for release 3.92.6. Handle files that
3819 have been moved to ../include, ../getopt, or ../bfd. Add
3820 saber.suppress and tests directory. Add config.status to
3821 the release (it will say "none").
3823 coredep.c: Minor formatting fixes.
3825 These changes were made in early December but only checked in now:
3826 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
3827 nindy-share/nindy.c: lint
3828 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
3829 register values coming back from the target; we store values
3830 in target byte order everywhere.
3832 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
3834 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
3836 * valprint.c (cplus_val_print, val_print_fields): New functions,
3837 which print C++ objects. They conspire to avoid printing a
3838 virtual base class more than once, following all the twists and
3839 turns of C++ virtual base rules.
3840 (val_print): Call the above rather than do it by hand.
3842 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
3843 symbol file, not for added files like shared libs. This really
3844 needs to be generalized to a timestamp per file.
3846 * core.c (cleanup_core): Avoid coredump if no core file.
3848 * config.gdb: Accept -host or -target in place of +host or
3851 * coffread.c (find_linenos): Avoid desupported BFD interface
3852 to line numbers. We still read them manually rather than using
3853 BFD's "generic" features.
3855 * gdbrc.tex, threecol.tex: Add GDB reference card and its
3857 Makefile.dist: Add refcard to OTHERS list for creating tar files.
3859 * Makefile.dist: Eliminate use of $< in explicit targets.
3861 * readline/Makefile: Use $< rather than $*.c, which does not
3862 include the VPATH in GNU Make.
3864 * tconfig/i960-bout, tconfig/i960-coff: These are identical
3865 copies of tconfig/i960, added for global configuration
3866 compatability. All i960 versions can read both coff and b.out.
3868 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
3869 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
3872 * TODO: Think of more things to do.
3874 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
3876 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
3877 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
3878 64-bit float conversion.
3880 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
3881 equivalent to sun?os4 so global config works.
3883 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
3885 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
3887 * main.c: Only declare linesize once; declare pagesize not at
3888 all, since it is never used.
3889 (main): Clear newly allocated line before it is used.
3891 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
3893 Further stabilization for the Intel 960.
3895 * Makefile.dist: Parameterize the location of the "include"
3896 and "bfd" directories, as well as "getopt". Add symfile.c.
3897 Link in both dbxread and coffread. Fix up "make depend" to
3898 rewack the locations of include, bfd, and getopt in its output.
3900 * README: Document moving include files, improve some of
3903 * coffread.c: Move common code out to symfile.c. Change
3904 symbol_file_command style interface to use new *_symfile_init
3905 and *_symfile_read interface under BFD. Use BFD internal
3906 info to locate line table, symbols, etc.
3908 * core.c (core_fetch_registers): Rename to get_core_registers
3909 to avoid confusion with fetch_core_registers.
3910 (register_addr): Move to coredep.c, which is already machine
3911 dependent. This leaves core.c pretty clean of dependencies.
3913 * coredep.c (register_addr): Accept this routine from core.c.
3915 * dbxread.c: Move common code (with coffread.c, etc) into new
3916 symfile.c. Each psymtab now contains a pointer to the
3917 format-dependent function that knows how to read it in. Make
3919 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
3920 (process_one_symbol): Add code to complain about a "compiler bug
3921 we muzzle here", if we actually see it.
3923 * eval.c (evaluate_subexp): Insert missing "break" statements
3924 in code that determines whether a variable is an lvalue in
3925 memory, register, or whatever. I detected this via a compiler
3926 bug in which it *almost* mashed out the whole switch statement.
3928 * gdb-int.texinfo: Add minor sections on configuring gdb for
3929 release, and about the README file.
3931 * infcmd.c (registers_info): Fix formatting somewhat. Still
3932 not as pretty as before, but it handles byte swapping.
3934 * remote-nindy.c: If data cache routines are interrupted while
3935 waiting for the remote end, be sure that any uninitialized cache
3936 blocks are on the free list, not on the valid list!
3938 * symfile.h: Flesh out this header file with all the various
3939 routines and variables that have been merged in from dbxread.c
3940 coffread.c, and symtab.c to symfile.c.
3942 * symfile.c: New file, containing code common to dbxread.c,
3943 coffread.c, and some code from symtab.c. All generic code for
3944 reading symbol files should be in here now.
3945 (unrecord_misc_function): Remove unused function.
3947 * symtab.h: Remove file-reading things to symfile.h.
3949 * symtab.c: Remove file-reading things to symfile.c.
3951 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
3952 to decode i960 fault types.
3954 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
3955 target.c: Change type of the "resume" function from int to void,
3956 since its result was never used.
3958 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
3960 * main.c: Replace "stupid" with "caution"; you now "set caution
3963 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
3965 * infcmd.c (do_registers_info): Call val_print to deal with the
3966 byte order of the registers being printed. FIXME, this makes
3967 the formatting of the output uglier.
3969 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
3970 defined, call it for signals the debugger doesn't itself use.
3971 The i960 uses this for more detailed fault information.
3973 * remote.c (remote_open): If arg is null, print help rather than
3976 * sparc-xdep.c (register_valid): Avoid declaring size, since
3977 various modules will think of various sizes depending on the
3978 architecture of their tm-file. FIXME, we need protection against
3979 actually entering one of those modules, which would clobber
3980 storage if not for the target architecture compiled into gdb.
3982 * stack.c (up_command, down_command): Always print the frame
3984 (up_silently_command, down_silently_command): New commands
3987 * i960-pinsn.c (reg), i960-tdep.c: Lint.
3989 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
3990 more parameters than it used to.
3992 * findvar.c (registers): Increase slop to 256 bytes, which should
3993 protect us against even most RISC machines with large register
3995 (locate_var_value): Move declaration inside related ifdef.
3997 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
3998 throughout, to avoid throwing away buffered input from the board.
3999 (nindy_wait): Supply_register takes addr_of_value, not value.
4000 (i960_print_fault): Renamed from i80960_fault.
4001 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
4002 (nindy_store_registers): Avoid regs_changed stuff, just stuff
4004 (nindy_create_inferior): Don't bother to write PC_REGNUM since
4005 we can set the PC in the call to proceed(). Unpush nindy_ops
4006 before pushing it on top, to avoid message to user. Eliminate
4007 commentary from Unix machines that just misleads here.
4008 (reset_command): Fix error message to suggest target command.
4010 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
4012 Release 3.92.5 as frozen.
4014 Stabilize the merged release...with help from lint, Saber C,
4017 Everywhere: Add include files needed to declare return types
4018 of functions called.
4020 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
4022 * breakpoint.h: Add undeclared breakpoint functions, and some
4023 functions for display handling since I couldn't think of a better
4026 * breakpoint.c (insert_breakpoints): Make code for disabling
4027 shared library bkpts more likely to work. It's used when we
4028 rerun a program and stop before the shared library has been
4030 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
4031 cast from pointer, so it squeezes through catch_errors.
4032 (bpstat_stop_status): Fix logic broken some time ago. We now
4033 always create a bpstat if the stop address matches a breakpoint,
4034 even if we don't stop there -- just like the old code used to do
4035 before I got my fingers into it (sigh).
4036 (breakpoint_1): Print "ignore count" after "stop only if"
4037 condition, since that's how it actually works.
4038 (mention): Handle watchpoints as well as breakpoints.
4039 (watch_command): use set_raw_breakpoint and mention to do most
4040 of the work (and initialize all the fields!). Only pass one
4041 arg to parse_c_expression, since that's all it takes.
4043 * command.c (not_just_help_class_command): Rename arg to args
4044 since we ignore "unused argument" warnings on vars named "args".
4045 inflow.c (child_terminal_info): ditto.
4046 infptrace.c (kill_inferior): ditto
4047 main.c (catch_errors, version_info, quit_command, pwd_command,
4048 source_command, dump_me_command, editing_info,
4049 set_history_size_command, set_history, show_history,
4051 stack.c (locals_info): ditto
4052 target.c (target_files_info): ditto
4053 valprint.c (set_input_radix, set_output_radix): ditto
4055 * core.c: Remove old variables for handling core and exec file
4056 sections (data_start, data_end, stack_start, stack_end,
4057 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
4058 text_end, exec_data_start, exec_data_end, text_offset,
4059 exec_data_offset, data_offset, stack_offset). They're
4060 superseded the more general build_section_table and
4062 (get_exec_file): Mention the `file' command.
4063 (read_memory_check): Rename to memory_error, and only call it
4064 in the case of an actual error.
4065 (read_memory, write_memory): call memory_error.
4066 (core_fetch_registers): Register section name is ".reg".
4068 coredep.c: Remove a bunch of crud now that all this file does
4069 is pull the registers out of a core file.
4070 (fetch_core_registers): Rewrite to actually work, I hope.
4072 dbxread.c: Use a.out.gnu.h, not system a.out, now.
4073 Replace index() with strchr(). Remove all the pre-BFD macro
4074 definitions for accessing the symbol file.
4075 (struct dbx_symfile_info): Encapsulate the information that
4076 dbx_symfile_init needs to pass to dbx_symfile_read in this
4079 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
4080 dbx_symfile_discard): Rearrange symbol file reading to divide
4081 the format-specific part from the format-independent part,
4082 leaving the format-independent part such as file name expansion
4083 and opening in symtab.c. This replaces
4084 partial_symbol_file_open and partial_symbol_file_read.
4085 Symbol_file_read, add_file, add_file_target_command,
4086 add_file_addr_command move to symtab.c. Pass an explicit
4087 "mainline" flag for when reading the main symbol table, rather
4088 than relying on the offset address to be zero or nonzero.
4090 (dbx_symfile_read): Don't allow void *'s to be printed as
4092 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
4093 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
4094 macro" debug version really work.
4095 (read_dbx_symtab): Remove unref'd parameter inclink.
4096 Avoid swapping N_SLINE symbols, for speed.
4097 Merge N_TEXT!N_EXT case with the other external symbol
4098 definitions' case. Add comments.
4099 (start_psymtab): Allocate the symfile name in the psymtab on
4100 the psymbol_obstack, rather than using the caller's storage.
4101 (end_psymtab): Only allocate a dependencies list if there are
4103 (psymtab_to_symtab_2): Use BFD when reopening file to read
4104 its symbols for real.
4105 (read_struct_type): Add FIXME comments where it needs work
4107 (read_huge_number): Add FIXME about overflows.
4108 (read_range_type): Add FIXME about comparing a long to 1<<32.
4110 * coffread.c: Minor changes to move things closer to the new
4111 regime with symtab.c and dbxread.c Major work is still needed
4114 * exec.c (exec_file_command): Remove old variables (see core.c
4116 (xfer_memory): If memory transfer is right at the end of a
4117 section, don't lose.
4119 * findvar.c (get_saved_register): If value is in a real
4120 register, LVAL is lval_register, not lval_memory.
4122 frame.h: Declare print_sel_frame and record_selected_frame.
4124 gdb-int.texinfo: New file, for GDB internals documentation.
4125 Very simple, unformatted doc of cleanups is there for now.
4127 gdbcore.h: Remove obsolete variables that described a.out
4128 section addresses and offsets. (See core.c above.)
4129 Declare fetch_core_registers and registers_fetched.
4131 getopt.c: Declare char *alloca(); even on SPARC.
4133 infcmd.c (run_command): Call target_kill rather than
4135 (step_command, next_command, stepi_command, nexti_command):
4136 Declare from_tty parameter even though we don't use it.
4137 (run_stack_dummy): argument BUFFER is a char array, not
4138 a pointer to REGISTER_TYPE.
4139 (finish_command): using_struct_return needed a value *,
4140 not a struct symbol *.
4142 * infptrace.c (child_xfer_memory): To avoid dependency on
4143 where sections are in memory, try PT_WRITE_D and if that fails,
4144 try PT_WRITE_I. Most Unixes don't care which you use.
4146 * infrun.c (step_resume_break_shadow): Change to array to
4147 match other breakpoint shadow storage.
4148 (clear_proceed_status): Pass address of bpstat to
4149 bpstat_clear, not the bpstat itself.
4150 (child_create_inferior): FIXME comment about if the child
4152 (start_inferior): Remove old function.
4153 (child_open): Use target_kill rather than kill_inferior.
4154 (wait_for_inferior): Ditto.
4155 (insert_step_breakpoint, remote_step_breakpoint): Use
4156 new step_resume_break_shadow.
4158 * inftarg.c (child_wait): If all child processes die,
4159 pretend that the one being waited for exited with signal 42.
4161 * main.c (command_line_input): When scanning for comments,
4162 don't coredump on unclosed quotes.
4163 (quit_command): Use target_kill rther than kill_inferior.
4164 (_initialize_main): Rename class_user from "user" to
4167 * printcmd.c (print_command_1): Initialize "fmt" if no format
4168 is specified by the user.
4169 (print_frame_args): Only add to args_printed if we are
4170 actually fetching args from the stack (avoiding undefined
4172 (_initialize_printcmd): Remove bogus \{ from string.
4174 * remote-eb.c (eb_open): Avoid coredump on no argument.
4176 * remote-nindy.c: Bring out of Intel environment into new
4177 target environment. Remove all conditional compilation on
4178 I80960. Massive hacking throughout.
4179 (nindy_xfer_inferior_memory): New routine stolen from
4181 (nindy_create_inferior): New routine pieced together, probably
4182 not quite working yet.
4183 (nindy_ops): New target_ops struct for nindy.
4185 * remote-vx.c: Use write_memory rather than target_write_memory
4186 to get error checking.
4187 (vx_add_file_command, vx_open): Use symbol_file_add rather than
4189 (vx_create_inferior): Use target_terminal_ours...
4191 * signame.c (_initialize_signame): Always initialize, since
4192 we need the table for things other than psignal.
4194 * solib.c (solib_add): Use symbol_file_add, not add_file.
4195 (solib_address): Return boolean result rather than struct
4196 pointer which nobody else knows the type of.
4198 * sparc-tdep.c, valops.c: Use write_memory rather than
4199 target_write_memory, to get error checking.
4201 * stack.c (locals_info, catch_info, args_info,
4202 get_selected_block, frame_command, up_command): Use
4203 target_has_stack, rather than have_inferior_p or
4206 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
4208 * symfile.h: New file, defining the interface between the
4209 generic and object-file-specific symbol reading code.
4211 * symtab.c: Move generic symbol-reading interface to symtab.c,
4212 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
4213 table to map BFD targets to symbol-reading modules in GDB.
4214 Change index to strchr.
4215 (lookup_struct_elt_type): Use error() rather than hand-made
4216 simulations thereof.
4217 (lookup_partial_symbol): Speedup slightly when length == 0.
4218 (symbol_file_add): New function.
4219 (symbol_file_command): Call it.
4220 (symfile_open, symfile_init): New function.
4221 (add_file_target_command, add_file_addr_command): moved from
4224 * target.c (target_command): use target_kill.
4226 * target.h (target_files_info): Don't declare, never called
4229 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
4230 files to determine stack end address.
4232 * valarith.c (value_x_binop, value_x_unop): Change error message
4233 to be more useful. Pass proper argument to value_struct_elt.
4235 * valops.c (value_assign): FIXME comment that long long
4236 bitfields will break here.
4238 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
4239 Update `make saber_gdb' to work better.
4241 * TODO: A woman's work is never done.
4243 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
4244 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
4245 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
4246 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
4247 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
4248 valops.c, valprint.c, exec.c: Lint.
4251 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
4253 Continuing Intel 960 port merge of GDB.
4255 * Makefile.dist: Merge i960 "nindy-share" files. Rename
4256 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
4257 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
4258 Wack over "make depend" so it handles files in subdirectories
4259 vx-share, nindy-share, bfd, and in the current directory.
4261 * blockframe.c (get_prev_frame_info): Remove fatal error
4262 if stack not defined.
4264 * core.c (core_open, core_detach): New functions that handle
4265 the old "core-file" command as "target core" and "detach" instead.
4266 (core_file_command): Call them.
4267 (core_xfer_memory): Use common routine xfer_memory.
4269 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
4270 dbxread now uses bfd for everything but symbol reading itself.
4271 BFD internals are used to drag out the relevant file offsets.
4272 (partial_symbol_file_open): Change args all around for BFD.
4274 * symtab.c: Rename "value" to "val" everywhere, so we can
4276 (symbol_file_command): New command, moved from dbxread.c
4277 and coffread.c. It uses BFD to read the file, then vectors
4278 based on its type, to dbx or coff symbol readers.
4279 * symtab.h: Extern a few vars for symbol_file_command.
4281 * target.h: Breakpoint takes a char * save area, not a char **.
4283 * valprint.c (val_print): When unpacking bitfields, offset
4284 the address in gdb of the value, if it is declared with a shorter
4285 type. Remove the last "runtime kludge test" of host byte order.
4287 * utils.c: Remove old my_bfd_read routine.
4289 * stack.c (frame_info): Use target_has_stack. Print program counter
4290 register's actual name rather than "pc", since it's called the
4291 "ip" (instruction pointer) on the i960 (sigh).
4293 * target.c (target_command): Add command for selecting a target
4294 type and calling its open routine. This is used for initiating
4295 communication with a particular target, in a generic way.
4297 * tm-i960.h: Update for modern gdb. Remove semicolons from
4298 various macros. Handle reading struct return convention, and
4299 error-out attempts to return structs with the "return" command.
4300 Be sure gdb doesn't think we know how to call functions in the
4303 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
4304 to i960_xxx in lower case.
4305 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
4306 not being defined yet.
4308 * remote.c (remote_open): Call start_remote to initialize
4309 wait_for_inferior during open.
4310 (remote_xfer_inferior_memory): Return length written rather
4313 * remote-vx.c (target_command -> vx_open): Use new generic
4315 * remote-eb.c, inftarg.c, exec.c: ditto.
4317 * infrun.c: Fix comments.
4318 (attach_program -> child_open): Use new generic target command.
4319 (wait_for_inferior): Clear saved register values before target_wait,
4320 so target_wait can set some of them if convenient.
4322 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
4323 Return success indicator, not void.
4324 (child_xfer_memory): Avoid fetching initial word if we'll
4325 overwrite it anyway.
4327 * infcmd.c (attach_command): Use new generic target open routine.
4328 (_initialize_infcmd): Update doc on attach and detach commands.
4329 (do_registers_info): Merge in a byte-order problem as a FIXME
4332 * findvar.c (find_saved_register): Avoid problem in current frame.
4333 (read_relative_register): Ditto.
4334 (write_register): Convert byte order on the way out.
4336 * exec.c (file_command): Add.
4337 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
4338 (xfer_memory): Common function between core_xfer_memory and
4340 (exec_xfer_memory): Use it.
4342 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
4344 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
4345 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
4346 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
4348 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
4350 Merge Intel 960 port of gdb, continuing...
4352 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
4353 symbol_file_command): Pass from_tty arg to hush 'em up.
4355 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
4356 Add magic numbers for 960 COFF format.
4358 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
4360 Merge Intel 960 port of gdb, from Intel "1.2" release.
4362 CHANGE_LOG entries from their port, which was based on
4365 Thu Sep 6 11:02:22 PDT 1990
4366 Remove temp file if download is interrupted.
4368 Wed Aug 1 09:08:33 PDT 1990
4369 Now uses binary protocol to talk to NINDY.
4370 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
4371 Times out after 5 seconds when trying to talk to NINDY.
4373 Tue May 29 12:54:49 PDT 1990
4374 Added variable baud rate (-b switch).
4375 Source code reorganization.
4377 Thu Apr 26 11:09:55 PDT 1990
4378 More cleanup of batch mode; specifically, execute "-s", "-e", and
4379 "-se" switches as soon as they are encountered on the invocation line.
4381 Fri Apr 20 13:47:15 PDT 1990
4384 Thu Apr 19 09:54:28 PDT 1990
4385 Add 'reset' command.
4387 Wed Apr 18 09:48:07 PDT 1990
4388 After opening remote tty, wait for 1 second to go by without input
4389 from it before trying to talk to NINDY (fixes problems with the
4390 Heurikon HK80/V960E).
4392 Mon Apr 4 16:33:05 PDT 1990
4393 Some output was not being suppressed in 'batch' mode.
4395 Thu Mar 22 15:31:11 PST 1990
4396 Ask user if old symbol table should be deleted when new file is
4399 Allow user to run a program downloaded before gdb960 was brought up.
4401 Correct "exec-file" help message for i80960 context.
4403 Correct bug in calculating user space address: could occasionally
4404 corrupt user program.
4406 Make sure to zero low-order bits in rip's because of bug in 960CA
4407 A-step part: could cause operation faults when "next"ing across
4410 Correct bug that made it impossible to get source line numbers for
4411 code loaded at addresses higher than 0x7fffffff.
4413 Wed Jan 10 12:43:22 PST 1990
4414 Open remote tty for exclusive use.
4416 Fri Jan 5 12:14:42 PST 1990
4417 Correct disassembly (CA manual was right after all):
4418 opcode for sysctl is 0x659
4420 Mon Oct 23 12:03:04 PDT 1989
4421 Use G960BASE and G960BIN environment variables to find 'sx' utility.
4423 Mon Oct 16 14:15:09 PDT 1989
4424 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
4426 Mon Oct 2 15:56:31 PDT 1989
4428 Added 960CA disassembly support.
4430 To simplify maintenance:
4431 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
4433 - eliminated opcode.h: incorporates tables into i960-pinsn.c
4434 - moved 960-specific routines from i960-pinsn.c to i960-md.c
4435 - made disassembly interface identical to that in gdmp960.
4439 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
4441 * target.h: Allow targets to stack. Add target_has_memory,
4442 _registers, etc. Restructure memory access and "info files"
4443 to walk the target stack.
4444 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
4445 target.c: Change tables to match target.h.
4446 * inflow.c (child_mourn_inferior): pop child_ops.
4447 (generic_mourn_inferior): Use new has_stack flag.
4448 * infptrace.c (child_xfer_memory): New memory regime.
4449 * inftarg.c (child_files_info): New "info files" regime.
4450 * remote-eb.c: New memory regime, new info files.
4451 * remote-vx.c: New memory regime, new info files. Now use
4452 separate targets for VxWorks attachment to machine, and
4453 actually running a process under VxWorks, since one has
4454 stack & execution & regs and the other doesn't.
4455 * remote.c: New memory regime, new info files.
4456 * sparc-xdep.c (fetch_core-registers): New memory regime.
4457 * target.c: New routines and support for stacked targets,
4458 new memory regime, new info files regime.
4461 Generalize section handling for an arbitrary number of sections,
4462 including use of the new BFD (binary file) library.
4463 * gdbcore.h: Add struct section_table.
4464 * exec.c (build_section_table): Iterate all sections and
4465 record what gdb needs to know about them.
4466 (exec_command): Use it.
4467 (exec_xfer_memory): Use the table.
4468 (exec_files_info): Print the table.
4469 * core.c (core_file_command, core_xfer_memory, core_files_info):
4471 * source.c (find_source_lines): Use bfd_get_mtime.
4472 * dbxread.c: Quick changes to make it compile with new BFD.
4473 * utils.c (error): Avoid using bfd_error in generic routines.
4475 * core.c (core_fetch_registers): Get from the ".regs" section of
4477 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
4479 * inferior.h (attach_flag): Export.
4480 * infcmd.c (run_command): use new target_create_inferior.
4481 * infrun.c (child_create_inferior): Don't return result.
4482 * Makefile.dist (VERSION): 3.91.4.
4484 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
4486 * breakpoint.c (bpstat_num): Handle breakpoints which have
4487 since been deleted, such as temporary breakpoints.
4488 infcmd.c (program_info): ditto.
4490 * core.c (core_file_command): Display the frame where the core
4495 * remote-vx.c (target_command): Merge in target command from
4496 targ-vx.c. A few other cleanups.
4498 * TODO, Projects: Lots more stuff to do...
4500 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
4502 Massive changes to wall off the remote-debugging interface
4503 behind a function vector. The port to handle VxWorks targets
4504 is also part of this.
4506 All files: Replace references to renamed functions,
4507 remove references to remote_debugging, remove references to
4508 have_include_file, have_core_file in favor of target_has_stack,
4509 target_has_memory, etc.
4511 * Modularize the breakpoint interface.
4512 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
4513 a breakpoint instruction.
4514 breakpoint.c: struct breakpoint's shadow_contents now sized as
4516 (insert_breakpoints): Vector to target to install breakpoints.
4517 (remove_breakpoints): Vector to target here too.
4518 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
4519 sparc-tdep.c (single_step): Use new breakpoint interface for
4520 the single-step breakpoints.
4521 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
4522 New file, contains routines to insert and remove breakpoints by
4523 reading out the old contents and later replacing them. This is
4524 how ptrace breakpoints work, and many remote systems as well.
4526 * tm-vxworks68.h: New config file, overrides a few things for
4527 Wind River's preferences.
4529 * target.h: New file, for transfer vector used to talk to the
4530 inferior (child, attached, core, exec, remote, etc). All accesses
4531 to the thing being debugged should come through these vectors.
4532 target.c: New file, routines to handle transfer vector.
4533 (various files): Add transfer vectors XXX_ops for the various
4534 targets and pseudo-targets (core files, etc) we support.
4536 * breakpoint.c (bpstat_stop_status): Further explorations of
4537 watchpoints and why things don't work all the time.
4538 (bpstat_alloc): New fn to allocate a bpstat and chain it.
4540 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
4541 the local gdbinit if it doesn't already have it.
4543 * core.c (core_ops): add and install.
4544 Allow core debugging without exec file.
4546 * dbxread.c (free_and_init_header_files): Merge two fns.
4547 (end_symtab): Free named symbol table when a new version comes in.
4548 (read_dbx_symtab): Relocate all kinds of symbols with base
4549 address. First step toward handling different text, data, bss
4551 (add_file_addr_command): Renamed add_file_command.
4552 (add_file_command): Vector to remote handler.
4553 Add "load" as an alias for "add-file" command.
4555 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
4556 non-returning functions.
4558 * exec.c: Add exec_ops, and push it as a target when an exec
4561 * infcmd.c (run_command): Pass executable file name and arg list
4562 separately when starting an inferior. Permit "run" when no exec
4563 file is specified, for VxWorks.
4564 (detach_command): Move to child_detach in inftarg.c.
4566 * inftarg.c: New file. Unix-child-specific routines, and the
4567 child_ops structure.
4569 * inferior.h (registers): Export "registers" as the way for
4570 target dependent register handlers to find gdb's local copy of
4571 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
4572 since it is now used by places that want wait_for_inferior to
4573 handle the grunge but want to see every trap from the inferior.
4575 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
4576 Eliminate remote_debugging hooks in terminal handling.
4578 * infrun.c: Replace start_inferior with child_create_inferior.
4579 Move all the hair of Unix shells and ptrace idiosyncracies into
4580 child_create_inferior, so remote handlers don't have to deal.
4581 Remove running_in_shell. Rename stop_after_attach to
4582 stop_soon_quietly, and use it in a few other places where we want
4583 to just call wait_for_inferior and get control back on the first
4584 trap. trap_expected now never takes a value > 1.
4585 (init_wait_for_inferior): Initialize static vars when a new
4588 main.c (gdbinit): Add new hook for .gdbinit file name, let
4589 it be overridden by config files as GDBINIT_FILENAME.
4590 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
4591 Both of these are used for VxWorks gdb.
4593 mcheck.c: rename include file "gmalloc.c" to avoid problems
4594 with system include file "malloc.c".
4596 param-no-tm.h: New include file, same as param.h but does not
4597 include the default "tm.h" file. This is used in files where
4598 the target is known, e.g. remote-eb.c or sparc-xdep.c.
4600 param.h: Now just a shell that includes tm.h and param-no-tm.h.
4602 remote-vx.c: New file, VxWorks remote debugging support. Uses
4603 RPC routines that are shared with the target system, in directory
4606 remote.c: Vectorize remote interface.
4608 source.c: Globalize source_path, and make an alias "l" for "list"
4609 since we now have the "load" command.
4611 sparc-xdep.c: Use new param-no-tm.h.
4613 symmisc.c (free_named_symtab): Add new function from Wind River.
4614 However, ifdef it out for now while we think about what it should
4617 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
4619 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
4620 non-Unix-children handle this with their own code in the target
4623 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
4624 source and target lists. Add vx-share to default list of include
4625 directories. Add new files to src and target lists: mem-break,
4626 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
4627 ${srcdir} versions of munch and createtags are used.
4629 * valops.c (find_function_addr): Split out of call_function.
4630 (call_function_by_hand): Rename call_function; this function
4631 calls functions in the target by laboriously patching the target
4632 word-by-word with the right stack, args, regs, etc.
4635 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
4637 Handle AMD 29000 a bit better.
4639 * remote-eb.c (readchar): Mask received char log to make it readable.
4640 (remote_start): Pass arguments down to executing program.
4641 Make startaddr unsigned.
4642 infrun.c (start_inferior): Accept args, pass them to
4644 infcmd.c (run_command): Pass args down to start_inferior.
4646 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
4647 the target object file format.
4648 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
4650 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
4651 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
4653 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
4655 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
4656 * TODO: We did a few things, we have more to do though.
4658 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
4659 * inflow.c (inferior_died): Clear deferred stores.
4661 * Debug problems with dummy frames and calls to the inferior.
4662 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
4663 * sparc-tdep.c (do_restore_insn): Simplify.
4664 (sparc_frame_find_saved_regs): Simplify and fix what we find.
4665 (sparc_push_dummy_frame): Simplify and fix what we push.
4666 (sparc_pop_frame): Slightly more hair here, deciding whether
4667 we are restoring a saved PC or returning to a return address in %i7.
4668 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
4670 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
4671 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
4672 * obstack.h (chunkfun): ditto.
4673 * defs.h (xmalloc, xrealloc): ditto
4675 * utils.c (quit): Grab the terminal from the child if necessary.
4677 * inflow.c (term_status_command): Rename to term_info, change
4680 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
4681 (is_delayed_branch): Speed up.
4682 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
4683 Still missing some float ops, and needs testing.
4685 * Support for input and output radixes other than base 10
4686 * defs.h (input_radix, output_radix): Declare.
4687 * expread.y (yyparse, parse_number): Handle changes of input
4688 radix, and ambiguous names-or-numbers in radixes >10.
4689 * printcmd.c (print_scalar_formatted): Print formatted hex
4690 numbers in varying column widths.
4691 * valprint.c (val_print): Use output_format to print scalar ints.
4692 (set_input_radix, set_output_radix, set_radix): Create.
4693 (set_output_radix): Set output_format from output_radix.
4694 (_initialize_valprint): add `set radix' but leave the others off.
4696 * main.c (execute_command): Let stupid questions be turned off.
4697 (_initialize_main): Handle "set stupidity", etc.
4699 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
4700 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
4702 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
4704 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
4705 bfd stuff is still screwed up, but with some manual work, it
4708 * breakpoint.c (bpstat_do_actions): Start over if a command
4709 proceeds the inferior, since the inferior will have stopped and
4710 will need to have its new stop-actions taken care of.
4712 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
4713 compiler fits, simplify it.
4715 * gdb.texinfo (directory command): Doc new dir command.
4716 source.c (directory_command): "dir" now puts things on the front
4717 of the path, moves dups up front, and handles multiple names
4718 on the command line, inserting each one in order. It also
4719 blows away cached line and full_filename info.
4721 * stack.c (backtrace_command): Skip "more stack frames follow"
4724 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
4725 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
4726 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
4727 The only odd one was Gould NP1, which had defined vprintf to
4730 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
4731 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
4732 variable, inspect_it.
4733 valprint.c (print_string, val_print): Use the global inspect_it
4734 to indicate whether to print in Epoch style or normal style.
4736 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
4738 * printcmd.c (call_command): add an alias for the "print" command
4739 which runs expressions and doesn't print the result if void.
4740 (print_command_1): implement it.
4742 * command.c: Remove #if 0'd code. Initialize all the fields
4743 in add_cmd (). Rename do_nothing_command to
4744 not_just_help_class_command, and make it externally visible.
4745 command.h: add user_commands to struct.
4746 * main.c (define_command): Don't overload c->function with a char
4747 string as well as a function pointer.
4749 * eval.c (evaluate_subexp): Reinstall tiemann changes to
4750 calling convention of value_struct_elt () that got dropped in
4753 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
4754 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
4756 * tm-sparc.h (POP_FRAME): replace some constants with defines.
4758 * sparc-xdep.c (store_inferior_registers): defer stores to regs
4759 until a good time (e.g. when we are about to run the child),
4760 saving ptrace calls.
4761 * infrun.c (proceed): handle DO_DEFERRED_STORES.
4762 * tm-sparc.h: define DO_DEFERRED_STORES.
4764 * sparc-xdep.c (store_inferior_registers): when storing float
4765 registers, don't store stack regs too. When storing the SP,
4766 however, DO store the stack regs too. This fixes a bug in which
4767 the dummy frame is not recognized when a call_function finishes,
4768 because its frame pointer (in the stack regs) was never
4770 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
4771 even though we don't know how to read them from an inferior.
4772 valops.c (call_function): Comment about storing SP.
4774 * infrun.c (save_inferior_status): Save away the original bpstat
4775 chain so it can be restored later. Install the copied version for
4776 use by whoever saved the status. It will be blow away by
4777 restore_inferior_status, and the original chain restored. This is
4778 important for people who have pointers into the original.
4780 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
4781 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
4782 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
4785 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
4787 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
4788 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
4789 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
4791 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
4793 * Merge Mike Tiemann's multiple inheritance changes from Sun.
4794 Store the baseclasses in a type struct starting from array element
4795 0 rather than from the unusual array element 1.
4797 dbxread.c: the above.
4798 (virtual_context): Add
4799 Read new debug information about which virtual function table
4800 a virtual function is from, and store it in fn_field.fcontext.
4802 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
4803 TYPE_FN_FIELD_STATIC_P.
4805 symtab.c: the above.
4806 valops.c: the above. Handle pointer casts of object *'s.
4807 (search_struct_method): Add.
4808 (value_struct_elt): First arg is now a pointer to a value, and is
4811 valprint.c: the above.
4812 values.c (value_virtual_fn_field): Add type arg. Handle
4813 offsetting to the proper object when calling virtual fns.
4815 (baseclass_addr): Add valuep arg.
4817 * README: Document the current state of BFD config (missing).
4818 * TODO, ChangeLog, Makefile.dist: Roll version.
4819 * WHATS.NEW: Add summary of changes since 3.5.
4821 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
4823 * dbxread.c (read_struct_type): Clear bit vectors whenever
4825 symtab.c (B_CLRALL): define.
4827 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
4828 using == rather than =. Huh... This fixes the dreaded problem
4829 wherein builtin_type_int becomes TYPE_CODE_FLT.
4831 * core.c (info_files): Show the inferior pid.
4833 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
4834 already knows how to look in the source directory.
4836 * Remove psymtab hair from many places. Remove duplicated code
4837 for searching symbol tables. Hide psymtabs from most places.
4838 Make it fast to get from a psymtab to its symtab.
4840 blockframe.c (blockvector_for_pc): Remove psymtab hair.
4841 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4842 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4843 dbxread.c: export psymtab_to_symtab, make it work if called N times.
4844 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
4845 new symtab completely. New psymtabs get symtab pointer
4846 initialized to zero. Remove MI warning printf.
4847 symtab.h: Comments. Add psymtab to symtab pointer.
4848 (PSYMTAB_TO_SYMTAB): New macro.
4849 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
4850 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
4852 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
4854 (print_frame_info): Avoid special-casing symbols that have not yet
4857 * source.c (open_source_file): Quick path if we have already
4858 located the source file by its full name.
4860 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
4861 find_pc_psymtab. When a name is found in the misc function
4862 vector, search the symbol table for its mangled name, not the
4863 name that the user typed.
4865 * bfd.h: Fix missing comment terminators, make #endifs match.
4867 * valarith.c (value_less): Handle unsigned int comparisons.
4868 Add FIXME about pointer compares, which assume host and target
4869 pointers are the same.
4871 * command.c (do_nothing_command): lint
4872 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
4873 fix comments on debug symbol format for visibility. Actually set
4874 visibility of symbols.
4875 main.c (echo_command): lint; use <readline/history.h>.
4876 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
4877 obstack.h (_obstack_blank): Rearrange pointer math to avoid
4878 pointing past end of allocated memory; saber complains.
4879 obstack.h: Declare the external functions that we use.
4880 valarith.h: use <string.h>
4881 solib.c (solib_add): lint.
4883 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
4885 * main.c (initialize_main): Default info_verbose to off, now that
4886 symbol reading is fast.
4887 (quit_command): Avoid clobbering exec_bfd while quitting.
4889 * Initial BFD (binary file diddling library) merger:
4890 coffread.c: Change AOUTHDR to struct exe_hdr.
4892 core.c: initialize initialized data at compile time.
4893 (core_file_command): Move from coredep.c, convert to bfd.
4894 (xfer_core_file): Convert to bfd.
4895 exec.c (exec_file_command): use bfd routines.
4897 mips-tdep.c: Remove exec_file_command and friends.
4900 * coredep.c: (fetch_core_registers) Convert core_file_command to
4901 fetch_core_registers.
4902 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
4904 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
4905 (my_bfd_read): More bogosity, which I don't think we call.
4906 (program_name): Remove this atrocity asap!
4908 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
4911 values.c: allocate_repeat_value was not clearing the
4912 optimized_out field.
4913 (value_static_field): minor stylistic fix (wrong macro was used).
4914 valops.c (value_struct_elt_for_address): didn't work for C++
4917 * signame.c (_initialize_signame): Initialize signal names once.
4919 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
4920 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
4921 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
4923 * remote-eb.c: Support user-settable baud rates on the serial port.
4925 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
4927 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
4929 * tconfig/sun3os4: Remove warning about native assembler,
4930 since it also occurs in the xconfig file.
4932 * findvar.c (registers): Allocate some slop after `registers'
4933 to prevent stray accesses from trashing the next variable.
4935 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
4936 on the sun-3, by changing the #ifdef from `sun3' (which is not
4937 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
4938 vars, which happened to follow `registers' in the executable.
4940 * readline/history.c (history_search): Heed gcc-2's advice
4941 and parenthesize && inside ||).
4943 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
4944 tm-29k.c: Insert FSF copyright headers.
4946 * remote-eb.c: Better comments.
4948 * Makefile.dist: Update to 3.91.6.
4949 * TODO: note PREPARE_TO_STORE problem.
4951 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
4953 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
4955 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
4957 * infrun.c (wait_for_inferior, at end): Don't set up
4958 prev_* if the inferior no longer exists.
4960 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
4961 CANNOT_EXECUTE_STACK.
4962 valops.c (call_function): Use it.
4964 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
4966 * inferior.h (PC_IN_CALL_DUMMY): New macro.
4967 infrun.c (wait_for_inferior, 2 places): Use it.
4969 * values.c (value_being_returned): Only use
4970 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
4972 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
4973 right thing for remote-eb.c.
4975 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
4976 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
4978 * blockframe.c: Put get_frame_saved_regs inside #if !defined
4979 (FRAME_FIND_SAVED_REGS).
4981 * findvar.c ({fetch,store}_registers): Check for
4982 REMOTE_{FETCH_STORE}_REGISTER macro.
4984 * findvar.c (get_saved_register): Add argument lval and
4985 change meaning of argument addr.
4986 findvar.c: Change calls to get_saved_register to reflect
4987 new calling convention.
4988 valops.c (value_assign): Use get_saved_register instead of
4989 find_saved_register.
4991 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
4993 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
4994 an (uninitialized) pointer to one. Use "&" when passing it
4997 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
4999 * coffread.c (getfilename): Use DGUX x_offset and x_name if
5002 * coffread.c (symbol_file_command): Put semicolon after
5004 Put safe_to_init_tdesc_context in #if defined (TDESC).
5005 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
5006 coffread.c: #include <sys/stat.h>.
5007 (read_coff_symtab): Typo: in_source_files -> in_source_file.
5008 Add missing ')' in check for "lc%" and friends. Remove
5010 Declare read_one_sym() at top of file.
5011 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
5012 MC68WRMAGIC can have the same value without causing a duplicate
5015 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
5017 * Allow a Makefile to be built without building the
5018 tm and xm file links that screw up builds in subdirectories.
5019 This is done with `config.gdb none', then you can do things
5020 like `make gdb.tar.Z'.
5021 * tconfig/none: Config file for no target system
5022 * xconfig/none: Config file for no host system
5023 * config.gdb: If no TM or XM files are called out by the
5024 host or target file, don't make links for them.
5026 * cplus-dem.c: Add documentation.
5028 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
5029 simple error, so the user's gdb doesn't crash due to some object
5030 file problem (e.g. somebody is rebuilding the file out from under
5033 * printcmd.c (print_address_symbolic): demangle the symbol.
5035 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
5036 Motorola copyrights in it. Make "make gdb.tar.Z" work.
5037 (alldeps.mak): sort and uniq all results from this; duplicates
5038 hose gdb.tar.Z link building. Remove RCS files from
5039 tconfig and xconfig. Add config files for sun386. Add
5040 a few odd files to OTHERS and HFILES.
5042 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
5044 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
5045 Roll version number to 3.91.5. Make lint work in bindir.
5047 * README: Document cross-debugging and new file structure.
5049 * blockframe.c: Lint. Include "value.h" to declare read_register.
5050 (find_pc_partial_function): remove duplicate line.
5052 * command.h: Lint. Declare error_no_arg and dont_repeat.
5054 * tm-news.h: Remove inadvertently duplicated stuff.
5056 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
5057 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
5059 * config.gdb: Allow `config.gdb host target' form. Clean
5060 up previous change that printed bogus messages when you just said
5063 * core.c: #include "command.h" for lint.
5066 * main.c: Remove some casts of enums. Lint.
5073 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
5075 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
5076 read it from memory. This will allow us to save ptrace calls
5077 eventually. Changed caller single_step too.
5079 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
5080 that we aren't going to use, saving many ptrace calls, especially
5081 when watchpointing or single stepping. Use some #define's for
5083 (store_inferior_registers): Ditto.
5084 (core_file_command): Use some #define's for constants.
5086 * tm-sparc.h: Add #define's for some register numbers, so we
5087 can eliminate the use of random constants in sparc-xdep.c.
5089 * stack.c (frame_command, print_frame_info, up_command,
5090 down_command) Remove frame_changed, since it
5091 causes a bug and doesn't seem to do anything useful. In some
5092 places it was used as a flag, in others as a stack level (?).
5094 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
5095 default is to use the portable (vprintf) version rather than the
5097 * xm-news.h (MISSING_VPRINTF): Add.
5099 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
5101 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
5103 * Remove stuff that forces -Bstatic linking of gdb, and warnings
5104 about linking debugged programs -Bstatic in the sun?os4 config
5105 files in tconfig and xconfig subdirectories.
5107 * main.c (main): Remove unreached exit(0) now that we exit
5110 * Create TODO file for online bug list. There are too many
5111 "little" bugs to keep track of on paper.
5113 * Change Projects file to refer to bug-gdb@cygnus.com
5114 rather than kingdon@ai.
5116 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
5118 * Makefile.dist (VERSION): 3.91.4 now.
5120 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
5121 (condense_misc_bunches): Add sanity check that misc_count is
5122 the same as the number of symbols in the bunch.
5124 * coffread.c: rename init_misc_bunches. Pass an argument
5125 to condense_misc_bunches (a zero).
5127 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
5128 every time we are called; don't rely on our caller to do it.
5129 (add_file): Remove call to init_misc_bunches.
5131 * mipsread.c: Only warn, don't error, if unknown symbol types.
5132 This keeps an old gdb from falling on its face if it sees newly
5133 extended symbol info. Rename init_misc_bunches.
5135 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
5137 * Merge in changes from Per Bothner for DECstations and other
5138 MIPS stuff. The rest is Bothner speaking:
5140 The next message is a merger of Alessando Forin's mips port with
5141 mine. I've tried to use my good if biased judgment to get
5142 the best of both. It *does* need testing.
5144 Some of the changes are general, *not* mips-specific.
5147 Didn't believe in little-endian bit order.
5148 There are still inconsistencies about whether flags
5149 like BITS_BIG_ENDIAN are integer (#if ...) or
5150 boolean (#ifdef ...). I tried to paper over them.
5152 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
5153 Moved some misc_function code that was common to
5154 {dbx,coff,mips}read.c to symtab.c.
5155 In the process, I think I cleaned things up a bit.
5156 At the same time, moved obsavestring and obconcat to symtab.c.
5159 Removed obsolete condense_addl_misc_bunches (use
5160 condense_misc_bunches(1) instead).
5163 Needed to include <sys/dir>, at least on DECstations.
5165 valops.c, mips-tdep.c, tm-mips.h:
5166 Added PUSH_ARGUMENTS macro to support funny argument-pushing
5167 conventions (when STACK_ALIGN is insufficient).
5168 Needed on mips, where doubles need 8-byte alignment,
5169 but ints only need 4.
5172 Removed cruft that was not being used.
5173 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
5176 Print $ before register-names (I think that makes things a little
5178 Never print two instructions, even if one delays.
5179 Removed hex-disassemble set_cmd. (This is not mips-specific,
5180 so I think the argument is whether it is generally worthwhile or not.
5181 I'm inclined to think not, given how easy it is to
5182 convert between radixes in gdb.)
5185 This is basically Alessando's code.
5186 It doesn't use obstacks; I changed it to use obstacks
5187 in a few minor places where using malloc causes a
5188 memory leak. (Probably, more places could/should be changed.)
5189 I added record_misc_function where it was missing.
5190 In symbol_file_command and add_file_command, I tried
5191 to make the code consistent with more recent versions.
5192 Minor sylistic changes in parse_procedure.
5193 Make a .gdbinfo. psuedo-symbol point back to the real
5194 procedure symbol (using the isym field).
5197 This is basically from my port, but with a lot of details
5198 and a number of routines merged in from Alessando's version.
5199 I basically used my code "raw" backtrace (use heuristics
5200 from the actual code, rather than symbol table info) - though
5201 the idea is Alessandro's. I feel my code is a little cleaner
5202 here, particularly in being a little more flexible, such as being
5203 able to handle gcc-produced code (which it now can).
5204 It also doesn't do frame caching (which is not useful
5205 more recent gdb versions).
5206 I also used my code for push_/pop_dummy, more or less.
5207 I tried to incorporate AF's code for testing sigtramp
5208 while backtracing; I probably got it wrong.
5209 Added mips_print_register, which tries to scrunch as much
5210 information as possible on a screen...
5211 Removed the skip-prologue set_cmd. As with hex-disassemble (see
5212 under mips-pinsn.c), I don't see anything mips-specific here,
5213 and I don't see it being all that useful anyway.
5216 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
5217 Use more register names (rather than hard-cases numbers).
5219 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
5221 * Hack up 3.90.11 changes:
5223 * Makefile.dist (depend): parameterize $(GCC).
5224 Add solib.c and solib.o.
5225 (readline): Fix vpath for both absolute or relative SRCDIR.
5227 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
5228 Also, let the part I didn't understand at least compile so
5229 I can test the rest. FIXME.
5231 * dbxread.c: Fix thinko using strcmp.
5232 (init_psymbol_list): declare static.
5233 (partial_symbol_file_open): Comment cleanups better, avoid
5234 cleaning up the string table since the caller will do that.
5235 Move the stat for mod time into symbol_file_command, temporarily.
5236 (There should be a mod time for each symbol file, eventually,
5237 to control its rereading. FIXME.)
5239 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
5240 SunOS, which gives error for shared libs otherwise. (From
5241 Schaefer, probably FIXME needs work for portability.)
5243 * solib.c: Move #include "param.h" to work.
5244 Lowercase all the Uppercase Letters In the Messages.
5245 (find_solib): Clean up inferior_so_name for debug printouts.
5246 Allow no argument, to mean all shared libraries.
5248 * symmisc.c: include param.h to get CLEAR_SOLIB.
5250 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
5252 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
5253 to 3.90.11. ChangeLog entries below are from this.
5255 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5259 * Makefile.dist (HFILES): Add tm-sunos.h.
5261 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5265 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
5267 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
5269 * sparc-opcode.h Added single-operand version of rett.
5271 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5273 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
5274 Put parens around gcc_p in expansion.
5276 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5278 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
5280 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5282 * Changes for Sun shared libraries:
5283 blockframe.c (find_pc_partial_function): If a non-text symbol
5284 is found, set *address = pc - FUNCTION_START_OFFSET.
5285 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
5286 Disable breakpoints instead of giving an error.
5287 source.c (select_source_symtab): Initialize cs_pst.
5288 symmisc.c: Call CLEAR_SOLIB if defined.
5289 symtab.h: Make text{low,high} CORE_ADDR not int.
5290 (psymtab): New field addr.
5292 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
5293 (record_misc_function): Give correct type for N_DATA symbols.
5294 (condense_misc_bunches): do "misc_function_count = j" regardless
5296 Take code which is shared between symbol_file_command and
5297 add_file_command and put it into partial_symbol_file_{open,read}.
5298 Split add_file_command into add_file_command and add_file.
5299 Make psymtab_to_symtab read in the string table if the file
5301 Two new parameters to read_dbx_symtab and start_psymtab.
5302 tm-sunos.h: New file.
5304 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5306 * infcmd.c: Change cont_command to continue_command and "cont"
5309 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5311 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
5313 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
5315 * values.c (USE_STRUCT_CONVENTION): Check for structures of
5316 size 1,2,4,8 rather than size < 8.
5318 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
5319 as necessary, not just once.
5321 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
5323 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5325 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
5327 * tm-news.h: Add CALL_DUMMY_*.
5329 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
5331 * config.gdb: In list_host, list_target, use ${i}, not $i.
5333 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5335 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
5337 * sparc-opcode.h: Change all store floating-point state register
5338 instructions to have the right match & lose fields.
5340 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5342 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
5344 config.gdb: If srcdir != ., create readline directory and
5345 copy a makefile into it.
5347 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
5348 consistency with POSIX.
5350 * breakpoint.c (bpstat_stop_status): Disable watchpoint
5351 when we exit its exp_valid_block.
5353 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
5355 * Makefile.dist: Bump version to 3.91.3.
5357 * Clean up handling of breakpoint commands (somewhat).
5358 Prompted by Tiemann bug report "cont 10" doesn't work any more.
5360 inferior.h: Add breakpoint_proceeded to inferior status struct
5361 and globals; save it and restore it.
5362 (clear_breakpoint_commands): Cleanup, remove old #define.
5364 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
5365 (save_inferior_status, restore_inferior_status): handle it also.
5366 (proceed): Remove earlier code that set breakpoint_proceeded.
5367 It is now set only in clear_proceed_status.
5368 (clear_proceed_status): Cleanup, use bpstat_clear rather
5369 than clear_breakpoint_commands. No callers need the stop_bpstat
5370 between clear_proceed_status and proceed.
5372 infcmd.c: Add breakpoint_proceeded definition and comment.
5373 (cont_command, jump_command, signal_command): Move call to
5374 clear_proceed_status right next to call to proceed.
5376 breakpoint.c (bpstat_do_actions): Avoid clobbering our
5377 caller's argument while running down the chain of breakpoints.
5378 Use new variable "breakpoint_proceeded" to determine when
5379 a command that it executes moves the inferior past the
5381 (bpstat_clear): Handle NULL argument.
5382 (bpstat_clear_actions): Avoid useless call to
5383 breakpoint_auto_delete.
5384 (delete_breakpoint): Clean up bpstat's that are pointing to
5385 the deleted breakpoint from the stop_bpstat chain.
5386 (breakpoint_auto_delete): Simplify.
5388 * Clean up handling of EOF, error on stdin, etc. This was
5389 prompted by a network problem that caused gdb to go into an
5390 infinite loop filling up its malloc'd memory.
5392 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
5393 not clear_breakpoints_commands, which is now gone.
5394 (main): If command_loop returns (e.g. from EOF on stdin), do
5395 a quit_command (looping back to command_loop if quit_command
5396 doesn't really quit).
5397 (command_loop): check result from command_line_input and
5398 exit if it returns NULL, rather than passing the NULL to
5400 (gdb_readline): Free malloc'd result space before returning
5403 * utils.c (query): Handle C-d to mean "yes", just as if the
5404 input was not a terminal. Also avoid infinite loop if EOF
5405 occurs in mid-input-line before newline. This allows
5406 query to be used at EOF on stdin with reasonable results.
5408 * infrun.c (proceed): Set breakpoint_proceeded.
5410 * values.c (value_as_long): Avoid infinite recursion for enums.
5411 (_initialize_values): Fix typo in help msg (kingdon).
5413 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
5414 RL_LIB for linking. This allows -lreadline for linking
5415 and nothing for dependencies, once readline is a real library.
5417 * config.gdb: Jim Kingdon: give useful error message if the
5418 host or target type is not recognized.
5420 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
5421 it just defines it. Dumb, but deal with it.
5423 * Jim Kingdon suggests:
5424 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
5426 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
5428 * Makefile.dist (VERSION): Bump version # to 3.91.2.
5430 * Clean up Bothner's changes.
5432 * blockframe.c (clear_pc_function_cache): New function.
5433 * blockframe.c: remake cache_pc_function_* static.
5434 * dbxread.c (symbol_file_command): remove references to
5435 cache_pc_function_* variables.
5436 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
5437 * printcmd.c: Avoid kludging a global variable (addressprint)
5438 to avoid printing the address of a string twice. Instead,
5439 pass the format letter 's' down low enough that it can be seen
5440 to avoid this problem.
5441 (print_formatted): Pass format arg to value_print.
5442 (restore_addressprint): Remove function.
5443 (do_examine): Avoid hacking addressprint, cleanups and such.
5444 (print_frame_args): Add a comment to a Bothner change.
5445 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
5446 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
5447 to wipe out the values cached in blockframe.c.
5448 * symtab.c (find_method): Add comment saying how big you must
5449 allocate to be "big enough". Per being terse again.
5450 * valprint.c (val_print): Handle format letter "s" to print
5451 strings without addresses. Add comment to vtbl printing code
5452 which casts with wild abandon. Rearrange reference-printing
5454 @0xaddr: value (print w/addressprint)
5455 value (print w/~addressprint)
5456 @0xaddr (parameter lists w/addressprint)
5457 or nothing (parameter lists w/o addressprint)

5461 * Merge more changes from Per Bothner:
5463 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
5464 annoying) that I tried to improve it. Here are my suggestions.
5466 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
5469 Do automatic de-reference when taking the address of a reference.
5471 Don't deref_ref when printing parameter lists.
5473 More attempts at treating refernences properly.
5475 In val_print, if deref_ref==0, don't print dangling " = ".
5477 Add COERCE_REF macro, which de-references an REF.
5479 * Merge changes from Per Bothner:
5481 * Fixed (Sony news)-specific configuration problems.
5482 * Fixed other problems with using vanilla pcc and libc (enum problems;
5483 assumption that vsprintf exists).
5484 * Some major speed-ups (finc_pc_partial_function now caches a match;
5485 parsing avoids duplicate symbol_lookup calls).
5486 * Changed handling of baseclasses (no longer use baseclasses field
5487 of struct type, use the first n_baseclasses fields instead).
5488 * Various minor changes/fixes, most C++-related.
5491 Cache the most previous match from find_pc_partial_function.
5492 (Save both low and high ends of matching function's pc range.)
5493 This speeds up the loop of infrun.c:wait_for_inferior quite
5494 a bit, and makes step/next commands much zippier.
5496 Added an enum->int cast (otherwise, some compilers barf).
5498 No longer set baseclass offset to 0, since multiple
5499 inheritance now mostly works.
5500 Added a number of casts, to shut up compiler warnings
5501 (after stabs where made enums, not ints).
5502 When discarding a symbol table (in symbol_file_command),
5503 must clear the cache introduced in blockframe.c.
5504 Don't convert $vtbl_ptr_type to vtbl any more.
5505 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
5506 Mask off sign bit emitted by g++ for virtual table offset.
5507 Set voffset to -1 (not 1) for static member functions.
5509 Changed parsing/lexing of names to avoid doing symbol lookup twice
5510 (once when lexing to determine symbol class, once for real).
5511 Now only call symbol_lookup once. Fields of 'this' win especially big.
5513 Subpress printing addr twice in the case of 'x/s addr'.
5515 lookup_basetype_type is no longer used.
5516 Add find_methods as recursive helper function to decode_line_1.
5517 This allows multiple inheritance to work.
5518 Also, once one or more matches has been found, do not look in
5519 base-classes. (Baseclass methods would be overridden, anyway.)
5521 Removed baseclasses array in struct type.
5522 Instead of using baseclasses[i], use fields[i-1].
5523 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
5524 Changed sign convention of voffset (previous was inconsistent).
5526 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
5528 Used to assume existence of vsprintf. Re-written to not need it
5529 if HAVE_VPRINTF is undefined.
5531 typecmp was too pessimistic. Made it less so.
5533 Don't print space after address.
5534 If vtable points to a misc symbol (with 0 offset), print it,
5535 since that indicates the actual class of the object.
5536 Changed ype_print_derivation_info to use new inheritance
5537 scheme (without baseclasses vector).
5539 In value_primitive_field, fixed some bugs left over from previous set of fixes.
5540 Also, changes needed because TYPE_BASECLASSES were removed.
5542 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
5544 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
5547 If there is no path set, and the symbols don't indicate what directory
5548 a file was compiled in, look in the current directory. But either
5549 a path or a known compilation directory will prevent this.
5552 Three independent bug fixes:
5553 * Remove the #if 0 block that breaks some stuff.
5554 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
5555 adapt gdb to either SunOS 4.0.* or 4.1.
5556 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
5559 Instantiate the class T when looking for methods in it. (Tiemann@sun)
5562 (type_print) Demangle the name being printed.
5563 (type_print_base) Handle botched demangling without coredump (tiemann).
5566 (check_stub_method): Document routine.
5567 (tiemann) fix bug for no-arg functions
5568 Avoid clobbering beyond end of malloc'd storage.
5569 Terminate the argument list properly.
5571 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
5573 * Changes merged by John Gilmore:
5576 In breakpoint_1, use new print_address_symbolic instead
5577 of find_pc_partial_function. (This forces use of assembler-level
5578 addresses, and avoids misleading non-mangled source-level names.)
5580 Generalize ansi argument such that -1 means skip arglist totally.
5581 Removed global variable print_ansi_qualifiers (which made
5582 code non-reentrant), in favor of extra explicit arguments
5583 to internal routines.
5585 Add new helper function print_address_symbolic.
5586 Use find_pc_misc_function instead of find_pc_partial_function
5587 (since we want assembler-level symbols here).
5589 Print unknown function as just "f (...)", not "f (...) (...)".
5590 Use new fputs_demangled explicitly.
5592 Fixed a typing violation (problem: value.h cannot be imported
5593 without renaming many variable in this file).
5594 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
5595 decode_line_1: Moved forward some never-reached code.
5596 Made decode_line_2 skip function prologues correctly.
5598 fputs_filtered should not demangle by default.
5599 Add new fputs_demangled to demangle on demand..
5601 Change value_struct_elt to use value_primitive_field (using recursive
5602 utility function search_struct_field). This allows foo.bar to work
5603 for multiple inheritance (so far only for data fields).
5604 Change check_field in the same way (recursive helper function
5605 to support multiple inheritance).
5606 (Note: there are more of these problems that I haven't fixed.
5607 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
5608 value_of_this: 'this' symbol name is now just "this", note "$this".
5610 Don't print static members.
5611 Avoid printing "members of <type>" if there are none.
5612 Simplified type_print_derivation_info by merging duplicate code.
5613 Remove useless blank lines in type_print_base (ptype command).
5615 Added declaration of new routine value_primitive_field.
5617 Added value_primitive_field which is generalized version of
5618 value_field that can handle multiple inheritance (non-zero offsets etc).
5619 Re-implemented value_field to call value_primitive_field.
5621 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
5623 * infcmd.c -- insert else to avoid 'delete env' coredump when you
5624 delete the whole environment. Karl Berry reported the bug.
5625 * source.c - fix openp to avoid //'s in filenames, which
5626 trigger an Emacs bug causing it to not be able to find files
5627 when running gdb in a window.
5628 * dbxread.c - zap the #if 0 that botches the add-file code.
5629 It seems to work a lot better without all the code commented out.
5631 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
5633 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
5636 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
5638 * Makefile - added a ${CFLAGS} to a couple of entries,
5639 added remote-sa.sparc.c
5640 * added remote.sa-sparc.c, a modification of remote.c
5641 which conducts a dialog directly with the SparcStation prom.
5642 * breakpoint.c, infrun.c, sparcdep.c added
5643 remote_insert_breakpoint(), and remote_remove_breakpoint()
5644 to breakpoint.c instead of directly writing breakpoint instructions.
5645 * sparcdep.c on remote_debugging,there is no need
5646 to remove signle step breakpoint instructions.
5647 * main.c added "-epoch" flag and "int epoch_interface" to main.c
5649 * printcmd.c - epoch interface sends lisp expressions to open up
5650 epoch windows on inspection.
5651 * valprint.c - added arrayprint, and addressprint and made adding
5652 format controls easier
5653 * wait.h added a couple of undef's because we were getting
5654 complaints about WSTOPSIG and WTERMSIG begin redefined.

5724 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
5725 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME

5750 step_resume_break_address != NULL, even if another_trap.
5751 If trap_expected and we enter sigtramp, then set up a
