19 it find the registers in the core-file header.
20 * coredep.c (fetch_core_registers): Take new argument, use it,
21 and pass it to register_addr to locate the block of registers.

24 * dbxread.c (read_dbx_symtab, process_one_symbol): Handle
25 Sequent N_FN_SEQ like everybody else's N_FN.
27 * main.c: Circumvent SCO cc bug with #if !!defined(USG).
28 * tm-i386v.h: #endif guck.
29 * xconfig/i386*: Remove -Dgetpagesize()=4096 kludge.
30 * xconfig/i386sco: Add HAVE_STRSTR to avoid ANSI bdeath.
31 * xconfig/tahoe: Add REGEX, which seems to be missing.
33 * coredep.c: Add <sys/types.h> for SCOnix.

59 (echo_command): Use printf_filtered, and force output out.
61 * dbxread.c (read_enum_type): Avoid Modula-2 kludge that breaks C
63 * i387-tdep.c (double_to_i387): Fix typo for double_to_ieee_extended.
64 * utils.c (_initialize_utils): If !ISATTY, don't paginate.

66 dec3100 to decstation.
68 Mon Oct 14 13:37:50 1991 Roland H. Pesch (pesch at cygnus.com)
70 * doc/gdb.texinfo: Catch up to changes recorded here in ChangeLog
71 (nodes Continuing and Stepping; Memory; Targets) clarifications
74 Fri Oct 11 23:27:06 1991 John Gilmore (gnu at cygnus.com)
76 * tm-{irix3,mips,nindy960,pn,symmetry,vx960}.h: Move

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

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

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

240 * language.c (set_language_command): Print useful help message,
241 and restore the language string after giving help.
242 * valprint.c (typedef_print): Print typedef in C or M2.
243 * symtab.c (list_symbols): Use it.
244 * main.c (main): Avoid any output before (gdb) prompt when -q.
245 * language.c (set_language_command): Handle errors by restoring
246 the language string to its current state (fix from A. Beers).
247 * doc/gdbint.texinfo: Roll in information from README. Rearrange
248 "how to install" and "how to print the doc" stuff so it drops
250 * configure.in: Rename rtpc CPU to romp to match config.sub.
251 * README, WHATS.NEW, TODO: Update for gdb-4.1.
253 Fri Sep 20 17:39:14 1991 Roland H. Pesch (pesch at cygnus.com)
255 * doc/gdb.texinfo: Updates from ChangeLog. set/show write,
256 autoloading shared libs, copyright etc on GDB startup, clean up $_
257 and $__ index refs, set/show listsize and related updates to list
258 cmd. New host/target configs.
260 Fri Sep 20 15:46:00 1991 Roland H. Pesch (pesch at cygnus.com)
262 * doc/Makefile: generate aux version-no file doc/gdbVN.m4
263 from main Makefile.in version definition
264 doc/gdb.texinfo: use version recorded in doc/gdbVN.m4 for current
266 Makefile.in (setup-to-dist): generate doc/gdbVN.m4
268 * doc/gdb.texinfo: merge new language-switching and lang-specific
271 Fri Sep 20 15:00:57 1991 Per Bothner (bothner at cygnus.com)
273 * mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
274 compilers (which may lack stddef.h).
276 Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com)
278 * dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and
279 N_WARNING are the same except for the N_EXT bit, so just use their
280 values alone, rather than OR-ing them with N_EXT.
282 Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com)
284 * mipsread.c (parse_lines): Deal with negative extended line
287 * c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid
288 global symbol conflicts.
290 Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
292 * .gdbinit: Move 'set complaints' to top, so it runs even in
293 case we aren't debugging GDB.
294 * language.c (_initialize_language): Fix type check and range
295 check documentation strings.
296 * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
297 language.c can use it. (Though language.c should really not be
298 handling warnings/errors the way it does, FIXME.)
299 * symtab.c (lookup_primitive_type): const lint.
301 Bugfix from Peter Schauer:
302 * source.c (lines_to_list): Make signed, to avoid comparison
303 going unsigned and complaining that -3 is too high for 21 lines.
304 * stack.c (lines_to_list): Ditto.
306 Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
308 * Makefile.in (HFILES): Add minimon.h.
309 (VERSION): Roll version number to 4.0.95.
310 (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
311 New rules for building distributions. Normal distribution
312 is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
313 one level up from here; it calls make-proto-gdb.dir to build a
314 directory `proto-gdb' which is an image of the release. The old
315 `gdb.tar.Z' rule still works too.
316 * config.sub, configure: Roll in latest from ..
318 Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
320 * doc/gdbint.texinfo: Reorder contents; reorganize new-host,
321 new-target, and new-config chapters; fix minor typos; come closer
322 to usual GNU markup conventions for @file @samp @code @var.
324 Thu Sep 19 17:04:12 1991 Per Bothner (bothner at cygnus.com)
326 Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
327 * mipsread.c (parse_partial_symbols): Enter the name of all
328 structs/unions... into the psymtab so we can access them if the
329 symtab is not read in.
330 * mips-tdep.c: Remove some unneeded #includes.
331 * xconfig/dec3100: Add HAVE_STRSTR.
333 Thu Sep 19 15:14:23 1991 John Gilmore (gnu at cygnus.com)
335 * Makefile.in: Circumvent Sun Make bug on *-exp.tab.o.
336 * c-exp.y, m2-exp.y: Lint.

338 * valprint.c (val_print_fields): Check for stub type.
339 * mipsread.c (_initialize_mipsread): Avoid using
340 builtin_type_void at initialize time.

442 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
444 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
445 entries are enclosed herein. Not all of these changes
446 have been merged into the master GDB sources -- check the
447 ChangeLog above here for the merge log.
449 Mon Jun 3 17:05:45 EDT 1991
451 m2-exp.y Created. Tested outside of GDB for a few days. Proper
452 operators were added, C specific operators and tokens
453 removed. yylex() revamped to some extent. Still things
454 missing from the grammar, such as sets.
455 Tested for two weeks in GDB v3.5.
457 Tue Jun 11 17:23:48 EDT 1991
459 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
460 so they are built-in. Sort of a hack.
462 Fri Jun 14 12:53:51 EDT 1991
464 m2-exp.y Added range checking for numeric constants. Any numeric
465 constant is assumed to be of builtin type INTEGER unless:
466 (1) it is octal or hexadecimal, in which case it is a
467 CARDINAL; (2) it is too big to fit into an INTEGER, in
468 which case it is a CARDINAL.
469 eval.c Added simple range checking for +, -, and * on integers.
470 Doesn't work very well for *, since 6 * 1,000,000,000 =
471 1,705,032,704, which fails the simple test of result >=
472 first_operand, no matter in what order the operands are.
474 Tue Jun 18 14:11:30 EDT 1991
476 Broke the parser into parts, one containing the C grammar and the other
477 containing code to be shared by all of the grammars.
479 The following files no longer exist:
484 The following files were added:
486 c-exp.y (The C grammar)
487 m2-exp.y (The Modula-2 grammar)
488 parser-code.c (Code that is shared by the above grammar)
492 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
493 now necessary to use the Bison compiler compiler, since it
494 will generate function/variable prefixes other than yy.
496 Tue Jun 18 16:47:49 EDT 1991
498 symtab.[ch] Added the external variable working_lang, than holds the
499 value of the current working language.
500 Added the ennumerated type language_mode, with the values
501 language_auto and language_manual, the former meaning that
502 GDB sets working_lang as needed, and the latter meaning
503 that the value of working_lang is totally under user
505 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
506 REAL, BOOLEAN and CHAR. Also added the type codes
507 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
508 utils.c Added set_language_command and show_language_command to
509 implement the GDB support commands "set language" and
511 expression.h A number of identifiers were added to the type exp_opcode
512 to facilitate Modula-2 builtin functions, integer
513 division, and array indexing.
515 Wed Jun 19 13:25:58 EDT 1991
517 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
518 if the language specified by working_lang requires the use
519 of strict typing of expressions. Eventually, even this
520 will be able to be changed by the user.
521 Added the macro RANGE_CHECK, which evaluates to non-zero
522 if the language specified by working_lang requires the
523 checking of a value against the domain of its type.
524 Eventually, even this will be able to be changed by the
526 language.[ch] Predicates involving types (simple_type, ordered_type,
527 same_type, integral_type, numeric_type, character_type,
528 boolean_type, float_type) are added. These predicates are
529 based on the current value of working_lang, and are handy
532 Wed Jun 19 15:39:34 EDT 1991
534 eval.c Added the function type_array_rank which computes the rank
536 valarith.c Added the funtion value_bool, which when given a integer
537 value.h value (ie. struct value *) as an argument, it returns a
538 boolean value (ie. struct value *) true if that integer
539 is non-zero, and a boolean value false otherwise.
540 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
541 will print out properly.
543 Wed Jun 19 16:36:34 EDT 1991
545 valops.c Added the function value_capitalize, which returns it
546 value.h argument capitalized if its argument is a lowercase
547 letter, or the argument unchanged if its argument is not a
549 valarith.c Added the function range_check_p, which returns non-zero
550 value.h if its value argument is between the integral bounds upper
552 Added the function range_check_enum_p, which makes sure
553 that its value argument is a valid member of the domain of
555 Added the function range_check_range_p, which makes sure
556 its value argument lies between the upper and lower bounds
557 of its type argument, which must be a ranged type.
558 Added the function check_array_index, which range and type
559 checks an index of an array.
560 Added the function value_multi_subscript, which computes
561 array[idx1,idx2...idxN], given a value array and an array
562 of values representing indicies.
563 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
564 unpack_long to work with TYPE_CODE_BOOL and
567 Wed Jun 19 18:04:08 EDT 1991
569 symtab.c Stored pervasive types in a structure and make
570 lookup_pervasive_type() a lookup function that was based
571 on working_lang. If lookup_pervasive_type() returned
572 non-zero, then that value was returned (a fix, since
573 before it simply wouldn't return the pervasive type.)
574 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
575 non-zero if the language specified by working_lang means
576 "conversion" when it says "cast".
577 valops.c Added the function value_real_cast(), which performs a
578 value.h *cast*, not a *conversion*, which is what value_cast()
579 does when it can. In particular,
580 value_cast(<float_type>,4) = 4.0, while
581 value_real_cast(<float_type>,4) = some mess.
582 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
583 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
584 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
585 and MIN on integral types. *NOTE*: These are currently
586 hardcoded to work only if there are 8 bits per storage
588 eval.c Made logical functions call value_bool to return a
589 properly typed boolean value, based on working_lang.
591 Thu Jun 20 11:55:27 EDT 1991
593 valprint.c Types now print out in a Modula-2 fashion. This works for
594 the cases when the type is printed out step-by-step, that
595 is, it doesn't work when the name of a structured type
596 (which includes the keyword "struct", etc.) is simply
598 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
599 since type specifications in C and Modula-2 are very
600 different. The C printing of a type is very recursive,
601 whereas in Modula-2 it is generally very simple. C has
602 type prefixes and suffixes, which have no real analogue in
603 Modula-2. Maybe type_print() should call a language
604 specific type printer. This is also advantageous if we
605 compile GDB to exclude some of the languages. We'll just
606 leave those functions out.
608 Thu Jun 20 16:57:10 EDT 1991
610 dbxread.c When reading the complete symbol table in (via
611 psymtab_to_symtab()), the number and types of function
612 arguments are added to a function type. define_symbol()
613 calls add_param_to_type() to accomplish this.
614 Assumption: when we come across a function definition
615 (N_FUN symbol with an 'f' or 'F' in the name), its
616 arguments will appear before another function definition.
617 When a function is found, a pointer to its type is placed
618 in the global in_function_type. Changes that
619 add_param_to_type() makes are to this global.
620 valprint.c The type of a function now includes (for Modula-2) the
621 types of its parameters.
622 eval.c Type checking and a check for the proper number of
623 arguments is now done for function calls. Not sure of the
624 impact this has on C++ member function yet.
626 Thu Jun 20 19:58:48 EDT 1991
628 valprint.c Rewrote the type printer. Broke it into two language
629 specific parts, adding the functions type_print_m2() and
631 An unfortunate consequence is this: if you debugging a C
632 program in Modula-2 mode (why?), info types does not work
633 well with regular expressions, since the types are printed
634 out in Modula-2 terminology, but stored in C terminology.
635 language.[ch] Added the functions new_type_last(), type_keyword(), and
636 type_sep() to aid in the printing of typedefs.
637 symtab.c Made the printing of typedefs as language independent as
638 possible through calls to new_type_last(), type_keyword(),
641 Fri Jun 21 11:50:26 EDT 1991
643 dbxread.c Check all incoming ennumerated types. If it looks like
644 Modula-2's BOOLEAN type, then change the type_code of the
645 type to TYPE_CODE_BOOL so we can process it as a boolean
647 valprint.c Replaced some of the 0x%x with calls to sprintf and
648 hexformat() in val_print().
649 language.[ch] Added the function hex_to_string(), which converts its
650 integral argument to a hexadecimal number (format is
651 language based) and returns the result as a string.
653 Mon Jun 24 12:25:07 EDT 1991
655 valprint.c Some functions call type_print_1() directly, instead of
656 value.h using type_print(), so they can specify where (column) to
657 print things. Since type_print() takes care of language
658 dependence, that needs to be called first. Added a
659 parameter depth to type_print() (so it is now like
660 type_print_1). Changed type_print to type_print_at, and
661 made type_print a macro that passes a depth argument of
663 symmisc.c Changed all calls to type_print_1 to calls to
665 Makefile.dist Made it possible to build GDB for a specific set of
666 depend languages. Do this by passing a definition for the macro
667 LANGS to make. LANGS should be a string containing a
668 space-separated list of language names (ie. LANGS="c m2").
669 The default is to build all languages. Note that grammar
670 files must follow the naming convention of <lang>-exp.y.
671 gdb.lang This holds the current value of the LANGS macro. It is
672 examined every time make is called, and is updated if
674 eval.c Added #ifdef _LANG_<lang> to these files.
675 expread.c Still need to add them to dbxread.c and coffread.c.
683 Mon Jun 24 16:33:11 EDT 1991
685 language.[ch] Added the functions hexformat_pre() and
686 hex_to_string_pre(), which take a prefix argument to
687 include in the format string. Thus, hexformat_pre("08") will
688 return "0x08x" (if the working language is language_c).
689 Made hexformat() and hex_to_string() calls to the above
690 with "" as the prefix argument.
692 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
693 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
694 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
695 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
696 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
697 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
698 valprint.c, vax-pinsn.c
700 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
701 calls to hexformat() and hex_to_string(). Format strings without
702 the leading "0x" were ignored.
704 depend Updated to take the above into account.
707 Tue Jun 25 15:27:18 EDT 1991
709 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
710 and type_check_t to keep track of the current state of
711 range and type checking.
712 main.c Added the variables range_mode, range_check, type_mode,
713 and type_check to record the current state of range and
714 type checking. Added initialization code to main().
715 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
719 Tue Jun 25 17:57:08 EDT 1991
721 dbxread.c process_one_symbol() updates the variable (enum language)
722 source_lang based on the extension of the filename
723 contained in the N_SO sybmol that started this symtab.
724 When end_symtab() is called, the value of source_lang is
725 put into the language field.
726 stack.c select_frame() sets working_lang (and possibly type_check
727 and range_check) to the language field of the symtab
728 associated with the frame that is selected if working_mode
729 is language_auto. If working_mode is language_manual, a
730 warning is printed and working_lang is not set.
731 language.c Added the function set_type_range(), which sets the value of
732 type_check and range_check (if their modes call for
733 automatic setting) based on the current value of
734 working_lang. A non-zero argument will cause the current
735 settings to be output.
738 Wed Jun 26 14:51:40 EDT 1991
740 eval.c Added range checks on assignment.
741 m2-exp.y Added the grammar for sets to the language. Currently,
742 these do not do anything except print an error message.
744 Wed Jun 26 17:01:04 EDT 1991
746 m2-exp.y Added the ability for parse_number() to parse negative
747 numbers. A global flag is set upon encountering a unary
748 minus. This was done to make, for example, 1 parse as a
749 CARDINAL, and not as an integer, per Wirth's examples in
750 Programming in Modula-2 ed.4.
751 valprint.c Added support for "set radix 2" by then setting
752 output_format to 't'.
753 eval.c Implemented range checking on subrange types. Added calls
754 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
755 Implemented MIN and MAX for ennumerated types. The
756 minimum value of an ennumerated type is defined by Wirth
757 as the first identifier, and the maximum as the last.
758 m2-exp.y Made octal numbers ending with "B" be characters and those
759 ending with "C" be numbers, per Wirth's book. (p. 34)
761 Thu Jun 27 14:11:52 EDT 1991
763 stack.c select_frame() now only sets working_lang, it does not
764 notify the user. If working_mode is language_manual, then
765 a warning is issued once.
766 main.c At the end of each call to execute_command(), working_lang
767 is checked against the local static (enum language)
768 current. If they differ and working_mode is
769 language_auto, the new settings of language, type and
770 range checking are printed out.
771 stack.c Modified frame_info() to include the language of the
772 current frame in the output of "info frame".
773 language.[ch] Added the function language_str() which returns the name
774 of the current language.
776 Fri Jun 28 15:33:14 EDT 1991
778 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
779 the language. INCL and DECL currently cause an error,
780 since sets are not implemented yet. INC and DEC are
781 implemented as PREINCREMENT/PREDECREMENT with one
782 argument, and as ASSIGN_MODIFY with two arguments.
783 eval.c Added type checking to the above cases.
784 value.h Added not_lval_constant to the lval_type ennumerated type.
785 not_lval_constant means that the value is a constant
786 value; that is 3 or 'a' or TRUE, not as in a constant
787 identifier. This is used to help coerce numbers such as 3
788 to either signed or unsigned numbers.
789 valops.c Added the function value_coerce_constants() which coerces
790 constant integers as following: if one is a constant and
791 the other is not, the constant's type is set to the type
792 of the other argument. If both are constants and one is
793 signed, the other is converted to a signed constant.
795 Sat Jun 29 17:26:29 EDT 1991
797 valarith.c Added a better range checker. It now checks range
798 (successfully) on integral operations [+-] (signed and
799 unsigned) for any C sized type. Still does not work well
801 int_in_size() returns an integer that is coerced to fit into
802 specified number of bytes.
804 Mon Jul 1 13:04:14 EDT 1991
806 language.[ch] Added the function binop_result_type(), which returns the
807 builtin (struct type *) type that would be the result of a
808 binop on the two values V1 and V2.
810 Wed Jul 3 19:22:53 EDT 1991
812 source.c Extended source_info() to include the source language in
813 the output from "info source".
815 Fri Jul 5 13:48:52 EDT 1991
817 utils.c Moved the support functions for the GDB set/show commands
818 dealing with language into language.c.
819 language.c Added the function language_info(), which displays info
820 about the current working language, type and range check
821 settings. Called via the GDB command "info language".
822 Added an initialization routine _initialize_language(),
823 that sets defaults for the language, type and range
824 variables and sets up the new GDB commands.
825 main.c Language setup moved to language.c.
828 Mon Jul 8 10:10:22 EDT 1991
830 valarith.c Debugged the range checker for arithmetic. Still does not
831 work for multiplication very well.
833 Mon Jul 8 12:40:37 EDT 1991
835 language.[ch] Added the function value_true() which returns non-zero if
836 its argument represents a boolean true value.
837 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
838 check the truth of an expression.
840 Thu Jul 11 12:51:34 EDT 1991
842 language.[ch] Added the predicate structured_type(), which returns
843 non-zero if the argument is a structured type.
844 Added the predicate pointer_type(), which returns non-zero
845 if the argument is a pointer type.
846 eval.c Added the ability to do addition and substraction on
847 pointers and integers. This case simply bypasses the
850 Thu Jul 11 14:41:42 EDT 1991
853 Added the symbol N_DEFD (0x4a) which is a definition
854 module dependency that is used by the GNU Modula-2
855 compiler and the linker. It is not important to GDB,
856 except that [dbx|coff|mips]read.c should ignore these
859 Fri Jul 12 16:07:00 EDT 1991
861 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
862 0 in val_print(). Also added statements to the else part
863 to coerce type (argument to val_print) to a pointer type
864 if it is an "array of unspecified length".
865 valops.c Added the function value_m2_string(), which returns a
866 (value) value which is a constant string, whose type is
867 (ARRAY [0..n] OF CHAR). The length field of the type
868 structure is set to zero, so it will be interpreted as an
869 "array of unspecified length".
870 stack.c Moved the language/frame mismatch check to
871 main.c:execute_command().
872 main.c The working language is recorded each time
873 execute_command() is executed. If working lang has
874 changed during its execution, then the new
875 language/type/range info is printed out for the user. If
876 the working language does not match the language of the
877 frame, a warning is issued.
879 Sat Jul 13 16:16:39 EDT 1991
881 eval.c Moved all the type-checking stuff for operators to
882 language.[ch] language.c. This is so we can keep language-specific
883 stuff (like for what type operators are defined) in
885 language.[ch] Added the function binop_type_check(), which checks to see
886 if its two (value) arguments are type-compatible with its
887 opcode argument. The opcode should represent an operation
888 involving an operator. Also added the macro function
889 unop_type_check, which calls binop_type_check with a
890 NULL second argument.
891 expprint.c Added Modula-2 operators to the op_print_tab, so info
892 expression.h break works correctly. Also added "op_string", which
893 returns the string corresponding to the (enum exp_opcode)
894 opcode that is its argument.
897 Sat Jul 13 18:26:18 EDT 1991
899 coffread.c Added code to record the type of function arguments with
900 each paricular function. Code is very similar to that
902 dbxread.c Moved add_param_to_type() to symtab.c
903 symtab.[ch] Added function add_param_to_type() from dbxread.c
905 *** NOTE: The above additions have not been tested.
907 Mon Jul 15 12:50:47 EDT 1991
909 langauge.[ch] Added the functions type_error and range_error, which work
910 like error() except if the type/range mode is set to
911 *_mode_warn, then they do not do a return_to_top_level(),
912 but merely print a warning.
913 Also changed [set|show]_[type|range]_command() to support
914 the new "warn" feature.
916 Thu Jul 18 17:50:54 EDT 1991
918 mipsread.c Added code to record the type of function arguments with
919 each particular function. Code is very similar to that
922 *** NOTE: The above additions have not been tested.
924 Fri Jul 19 11:19:10 EDT 1991
926 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
927 UMIN_OF_SIZE, which when given a size of a numeric type,
928 return the maximum and minimum value it can hold. UMAX...
929 and UMIN... return the result for unsigned types.
930 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
931 struct types. They call above macros.
932 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
933 avoid a name conlict with the above.
934 c-exp.y Added range checking on numeric constants in
935 parse_number() for completeness.
936 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
937 return 0 if working_lang is not language_c.
939 Thu Aug 8 14:17:22 EDT 1991
943 breakpoint.c Documentation strings of some commands changed to
944 eliminate the references to the C language where
947 Tue Aug 13 15:48:03 EDT 1991
949 m2-exp.y Added qualified identifiers to the grammar. The semantics
950 are slightly different from those of the GDB operator ::
952 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
953 type_exp, where type_exp is any valid type expression.
955 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
956 printcmd.c Modified ptype_command() so it actually parses the input
957 (necessary for type expressions with scope qualifiers).
958 Added the function ptype_eval() which expects an
959 expression composed of one OP_TYPE element.
960 *.[ch] Replaced all occurences of parse_c_expression with
962 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
964 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
966 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
968 Small fixes from Peter Schauer:
970 * infrun.c (child_attach): Lint.
971 * solib.c (find_solib): Handle shared libs version 2.
973 Small fixes from David Wood:
975 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
979 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
980 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
982 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
983 chars_per_line is at maximum (user typed `set width 0'). Fix
984 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
986 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
988 * coredep.c: include ptrace.h where necessary.
989 * mipsread.c(parse_lines): fix unsigned char problem that was
990 messing up line numbers on SGI's and possibly other MIPS based
992 * infrun.c (child_create_inferior): use better test to check
993 return val from setpgrp().
994 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
995 for sgi/irix support.
997 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
999 * mipsread.c (parse_symbol): Put non-static procedures
1000 in the global block.
1002 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
1004 Patch together `text_start' and `text_end' for 29K port.
1006 * exec.c (exec_command): If NEED_TEXT_START_END, define the
1007 variables and set them based on the exec file.
1008 * am29k-tdep.c: declare text_start.
1009 * valops.c (call_function_by_hand): declare text_end.
1011 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
1012 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
1013 because machines that do this will also have to know to
1014 set NEED_TEXT_START_END. Besides, it was a redundant way to
1016 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
1017 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
1018 NEED_TEXT_START_END.
1020 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
1022 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
1024 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
1025 Pass MUNCH_DEFINE to munch whenever we run it.
1026 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
1027 format string; use 0x%x instead.
1028 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
1029 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.

1031 * inflow.c: Handle `short' process group IDs.
1032 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
1033 and check for ptrace errors.

1035 (coff_symfile_init): Initialize text_bfd_scnum.
1036 (read_coff_symtab): Use it to find the text [and absolute?] sections.
1037 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
1038 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
1039 Merge target arm case with other "easy" cases. Add target
1040 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
1041 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
1043 * minimon.h, remote-adapt.c, remote-mm.c: Add.
1044 * munch: Cope with RT/PC putting fns in data segment.
1045 Restore ability to override `nm' by specifying MUNCH_NM.
1046 * xconfig/rtbsd, xconfig/ultra3: New host systems.
1047 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
1048 and remote-adapt. Remove encapsulated coff #define's (the
1049 support should go in BFD, and gdb shouldn't know or care).
1050 * tconfig/a29k-kern: Same, but for remote kernel debugging.
1051 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
1052 * tm-29k.h: Update BADMAG (though it should go away).
1053 Allow the register definitions to be overridden in another
1054 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
1055 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
1056 DUMMY_SAVE_GR96, for handling kernel calling conventions
1057 that use GR64+ rather than GR96+.
1058 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
1059 remote debugging of Ultra3 kernel. Includes tm-29k.h and
1060 overrides various things.
1062 * remote-mm.c (mm_attach, mm_wait): Handle attach like
1063 child_attach does, making a clean stop in the newly attached
1065 * remote-eb.c: Lint.
1067 * coffread.c: Make coffread independent of any particular
1068 variant of COFF. Avoid #include-ing any particular one except
1069 internalcoff.h. BFD now passes key values for symbol reading
1070 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
1071 and the symbol masks and shifts); use them.
1072 Remove obsolete end_of_text_addr.
1074 * exec.c: Remove unused include files.
1076 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1078 * Makefile.in (documentation targets): Pass $(M4).
1079 Bugfix from eggert@twinsun.com (Paul Eggert).
1081 * stack.c (down_silently_command): Check for stack existence.
1083 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1085 * Makefile.in (VERSION): Update to 4.0.3.
1087 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1089 * core.c (core_file_command): Print frame at coredump with
1090 its level number, by calling print_stack_frame.
1091 * frame.h: Add selected_frame_level, print_stack_frame.
1092 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
1093 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
1094 Change print_sel_frame and print_selected_frame callers to
1097 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
1098 * symfile.c (free_named_symtabs): Ditto.
1099 * main.c (main): wrap_here needs an arg.
1100 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
1101 (solib_add): Avoid noise.
1102 (solib_create_inferior_hook): Lint.
1103 (sharedlibrary_command): Move dont_repeat to here.
1104 * utils.c (error): Call wrap_here to force buffered output.
1106 Small patches from Peter Schauer:
1108 * coffread.c (start_symtab): Free any existing line_vector before
1110 (read_coff_symtab): Ditto for type_vector.
1112 * source.c (lines_to_list): New variable, replacing function.
1113 (all uses): Use as variable.
1114 (_initialize_source): Add 'set listsize' and 'show listsize'.
1115 * utils.c (lines_to_list): Remove function.
1116 * stack.c (print_frame_info): Use as variable.
1117 * defs.h (lines_to_list): Remove declaration.
1119 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1121 * breakpoint.c (insert_breakpoints): Restore warning about
1122 the program might be running in another process, but only for
1123 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
1124 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
1126 * utils.c (error): if error_pre_print is set, print the string
1128 * main.c (main, print_gnu_advertisement, print_gdb_version):
1129 Reformat legalese so it always prints, but acts as an "I'm here"
1130 message while symbols are being read. If any errors occur,
1131 print a few newlines to set off the message and start it at the
1132 left margin. Remove mention of "help" command, and don't yak
1133 about symbol reading.
1134 (catch_errors): Error string is now printed first in case of
1136 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
1137 suggest the "help" command.
1139 * Makefile.in (VERSION): Set to 4.0.2.
1141 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
1143 * .gdbinit: Remove useless "rr" command. Set complaints
1144 to 1 for people debugging gdb.
1146 * breakpoint.c, remote-vx.c: Reword strings printed by
1147 catch_errors callers.
1149 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
1151 * WHATS.NEW: "history write -> history save". Doc "write on/off".
1152 (Fix from kenc@viewlogic.com.)
1154 Fix some infrastructure to be able to cope with host and target
1155 machines with different sized basic types (ints, ptrs, etc).
1156 (Idea from pierre@la.tce.com (Pierre Willard).)
1158 * values.c (value_from_longest): Rename from value_from_long.
1159 Handle pointer types as well as integers, so that targets with
1160 different pointer sizes from the host can be accomodated.
1161 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
1162 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
1163 uses of value_from_long to value_from_longest.
1164 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
1165 the correct pointer type to value_from_long{est}.
1167 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
1169 * remote-vx.c: Remove obsolete code for calling functions via
1170 vxworks kludge interface (it referenced value_from_long).
1172 * valops.c (value_string): Find malloc with lookup_misc_func, not
1175 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1177 Make writing to files work properly. (Fixes to BFD are also needed.)
1179 * core.c (core_open): Open file ourselves, read or r/w, depending on
1180 write_files. Use bfd_fdopenr.
1181 * gdbcore.h (write_files): New variable.
1182 * exec.c (write_files): Define variable, add set&show for it.
1183 (exec_file_command): Use write_files to open for read or r/write.
1185 Make shared library reading happen automatically. These changes
1186 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
1188 * inferior.h (stop_soon_quietly): Add to exported variables.
1189 * infrun.c (child_create_inferior): call solib hook, if defined.
1190 (child_attach): call solib hook, if defined.
1191 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
1192 (find_solib): Use lookup_misc_func rather than hand-rolled.
1193 (symbol_add_stub): New stub for catch_errors.
1194 (solib_add): Avoid output if !from_tty. Catch errors rather
1195 than just calling symbol_file_add and bombing.
1196 (solib_create_inferior_hook): Interface with the target process
1197 to let it read and alloc shared libs, then figure out what it did.
1199 * core.c (validate_files): Fix typo, soften warning.
1200 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
1202 * utils.c (fputs_demangled): Avoid duplicate printing if
1203 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
1205 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
1206 (Fix from pierre@la.tce.com (Pierre Willard).)
1208 * main.c (catch_errors): Change argument to a char * from an int,
1209 since a char * can point to a struct full of glop, but an int
1210 is not guaranteed to be able to hold a pointer.
1211 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
1212 breakpoint_re_set_one, breakpoint_re_set): Adapt.
1213 * core.c (core_open, solib_add_stub): Adapt.
1214 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
1216 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1218 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
1219 by adding .NOEXPORT target.
1221 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1225 * Makefile.in (VERSION): Roll to 4.0.
1226 (gdb.tar.Z): Make refcard.ps as well, for shipment.
1228 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1230 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
1233 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
1236 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
1238 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
1239 reflect above name change
1241 * WHATS.NEW: correct pointer to refcard.
1243 * doc/gdb.texinfo: update New Features, Installing
1245 * doc/gdbint.texinfo: add short description of configure +template
1247 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1249 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
1251 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
1253 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
1254 tar file, add dependencies for referenced doc files.
1256 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
1258 * coffread.c, symfile.c, stack.c: saberized.
1260 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1262 * doc/refcard.tex: permuted Essential Commands sec
1264 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
1266 set/show symbol-reloading
1267 default set complaints 0
1269 RET-repeat disabled after prompted long displays
1270 processID (attach) interpretation of 2nd GDB cmdline arg
1272 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
1274 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
1275 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
1276 breakpoint.c, main.c: lint.
1278 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1280 Install new configuration scheme for GDB and friends.
1282 * config.sub: Translate ordinary names to three-part names.
1283 * configure: Use three-part names internally.
1284 * configure.in: Translate three-part names to filenames.
1286 * README, WHATS.NEW: Update for gdb-4.0.
1287 * Makefile.in: Roll VERSION to 3.99.
1289 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
1291 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
1292 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
1293 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
1294 to single structures rather than arrays; when passing
1295 their address, use &. This avoids trouble with bdead compilers.
1296 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
1297 instead. This avoids portability headaches.
1298 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
1300 * source.c (open_source_file): Avoid ANSI const bdeath by
1301 skipping declaration and then casting result value.
1302 * tm-hp300bsd.h: Clarify comment.
1303 * utils.c (strstr): Result is const char *; ANSI bdeath.
1304 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
1305 since system include file defines it differently from "defs.h",
1306 though the two are equivalent for our purposes.
1307 * tconfig/hp300bsd: Add m68k-tdep.o.
1309 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1311 * tconfig/sun*4: Remove warnings about system assembler.
1313 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1315 * mcheck.c: Avoid warning about undeclared abort fn.
1316 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
1317 it causes recursive calls to error() when used in cleanups.
1318 To do so requires that we make it a function, so we do.
1319 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
1320 * utils.c (do_cleanups): Remove the current cleanup from the
1321 chain *before* calling it, in case error() is called from it.
1322 The result won't be pretty, but won't be an infinite loop either.
1324 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
1326 * dbxread.c (read_struct_type): Grok anon structs for C++.
1327 (vb_name, vptr_name): Null terminate these strings.
1329 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1331 Minor bug fixes from BSD Net2 gdb:
1333 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
1334 returns 0, there is no previous frame.
1335 * breakpoint.c (commands_command): If !from_tty, don't call
1336 input_from_terminal_p().
1337 * dbxread.c (record_misc_function): Speed up slightly.
1338 (compare_psymbols): Ditto.
1339 * infcmd.c (do_registers_info): Take a second argument to
1340 determine whether to print float registers. "info registers"
1341 does not do so anymore. "info all-registers" does, now.
1342 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
1344 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
1345 * inflow.c (initialize_inflow): Set tflags_ours correctly.
1349 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
1350 executing_breakpoint_commands if we are interrupted by error.
1351 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
1352 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
1353 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
1354 catch_errors() so we can setup the frame regardless of whether
1355 the shared libs work.
1356 * ieee-float.c (double_to_ieee_extended): Get exponent from
1357 right place in little-endian systems. From John Carey.
1359 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1361 * main.c: Remove unused terminating_signals and catch_termination().
1362 (long_options): Terminate with a zero element.
1363 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
1364 (gdb_readline): Make call-compatible with readline.
1365 (init_signals): Improve comments re vfork vs. signal.
1367 * utils.c (prompt_for_continue): Use new gdb_readline().
1368 If we prompt for continuation, we don't let CR repeat the previous
1369 command, once we get back to a prompt. It's too easy to keep
1370 hitting CR, expecting "--more--" prompts, and have some long
1371 command start repeating on you.
1373 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1375 * blockframe.c (frameless_look_for_prologue): Speed up by
1376 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
1377 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
1378 Define two variants, one faster.
1379 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
1380 and return zero, rather than giving an error.
1381 (setup_arbitrary_frame): Initialize the PC in the new frame.
1382 (skip_prologue): Add a second arg saying whether we're just
1383 checking for a frameless function or not.
1385 * core.c (core_open, core_close, core_xfer_memory): Move
1386 section table pointers and bfd* into the target_ops.
1387 (core_open): Allow errors in shared lib reading, etc.
1388 (core_files_info): Describe shared library sections.
1390 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
1391 exec_files_info, set_section_command): Move section table
1392 pointers and bfd* into the target_ops.
1393 (add_to_section_table): Add BFD to section table.
1395 * target.c (target_xfer_memory, target_info): Pass target to
1396 xfer_memory and target_info functions.
1399 * gdbcore.h: Move struct section_table.
1400 * target.h: New home of struct section_table.
1402 * solib.c (solib_add): New argument is the target_ops whose
1403 section list is to be added to, if any. Reallocate the
1404 sections in that target to add any that come from shared libs.
1405 (throughout) so_sections renamed to sections.
1406 (solib_xfer_memory): Deleted.
1407 * tm-sunos.h (SOLIB_ADD): Add target argument.
1408 (SOLIB_XFER_MEMORY): Delete.
1410 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1411 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
1412 from target_ops. It's the same on all targets. Add two section
1413 pointers to target_ops.
1415 * stack.c (find_relative_frame): Dump ancient algorithm for
1416 "down", just use handy "next" pointers.
1417 (frame_command): Don't error if there is no stack; let user
1420 * inflow.c (new_tty_prefork, new_tty): New prefork routine
1421 modifies static state in the parent process; new_tty itself
1422 runs in the child and modifies the child's file descriptors
1423 to match the saved static state.
1424 * infrun.c (child_create_inferior): Call new_tty_prefork,
1427 * infptrace.c (child_xfer_memory): Add ignored target arg.
1428 * remote-eb.c (eb_xfer_inferior_memory): ''
1429 * remote-nindy.c (nindy_xfer_inferior_memory): ''
1430 * remote-vx.c (vx_xfer_memory): ''
1431 * remote.c (remote_xfer_memory): ''. Rename from
1432 remote_xfer_inferior_memory.
1434 * main.c (main): Only try to attach "corefile" argument if
1435 it starts with a digit.
1437 * symfile.c (symbol_reloading): New "set/show" variable.
1438 (symbol_file_add): Shorten message about symbol reading.
1439 (add_symbol_file_command): Merge with add_syms_addr_command,
1440 since this should work on all targets now.
1441 (stop_whining): Default to zero, to shut up complaints
1442 about bad symbol tables on many systems.
1443 (free_named_symtabs): Just exit unless symbol_reloading.
1445 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
1446 and add comment explaining shared library screw.
1448 * source.c: #if defined => #ifdef.
1450 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1452 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
1454 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1456 * doc/rdl-apps.texinfo: provide default readline-appendix finder
1457 (doc/Makefile knows how to make one for local config)
1459 * Makefile.in: use doc/Makefile for doc targets
1461 * doc/Makefile: GDB documentation now has its own Makefile
1462 doc/refcard.tex: renamed from "gdbrc.tex"
1463 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
1464 doc/gdbint.texinfo: add markup in "Cleanups" chapter
1467 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1469 * values.c (baseclass_addr): When reading target memory, use the
1470 length of the basetype, not the upper type. We've only malloc'd
1471 enough space for the basetype, leading to errors in free().
1473 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
1474 ends up as a function specially, since we know the actual type of
1475 the pointed-to address. This (somewhat) fixes display of
1476 expressions that include misc_function_vector names. Try `cond 1
1477 !strcmp("a","b")' then `i b'.
1479 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
1480 The child can be proceeded from inside wait_for_inferior in
1481 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
1482 getting skipped in that case.
1484 * expprint.c (print_subexp): Use filtered output, since the
1485 subroutines we call use it, otherwise the output is horribly
1486 mangled, since output of wrappable stuff comes out late.
1488 * Makefile.in: Bump VERSION to 3.98.1
1490 * infrun.c (child_create_process): Use execlp to find the
1491 shell to exec our target program. This requires some fiddling
1492 with `environ' since there is no execlpe().
1494 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1496 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
1497 Minor rearrangement of refcard permits two new make targets--
1498 gdbrc.dvi DVI output for refcard, using CM fonts
1499 gdbrc.ps PostScript refcard, using PS fonts
1501 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1505 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
1506 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
1508 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1510 * doc/gdb.texinfo: last changes for release.
1511 Minor typo and formatting fixes; incorporated most fixes remaining from
1512 filed mail commenting on earlier drafts.
1514 Added warnings: pipes don't work in run command;
1515 conditions are converse of assertions;
1516 step over fn without debug info goes to next fn;
1517 vars may have "wrong" values near fn entrance, exit
1519 Added example from Kingston on printing repeated nonadjacent values
1521 Added explicit mention that in Emacs gdb mode C-c and C-z are like
1522 shell mode for signals
1524 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
1525 doesn't sound so much like its parent "Stopping and Continuing"; also
1526 moved entries on continue to top of section, so they don't get lost.
1528 Improved installation directions in appendix, added manual formatting
1531 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1533 * configure.in: Remove xm.h and tm.h even if we aren't linking
1534 new ones, so "./configure sun4; ./configure none" does the right
1535 thing. Assume that alldeps.mak and depend are already built in
1536 srcdir, and avoid running "make" (particularly "make depend",
1537 which involves "gcc") from inside configure. Build Makefile
1538 directly rather than building Makefile.conf first.
1539 * configure: Regenerate with above changes.
1540 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
1541 to 3.98. Revise gdb.tar.Z procedure to produce a file
1542 called gdb-$(VERSION).tar.Z but which unpacks into a
1543 directory called "gdb". Move non-source files out of
1544 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
1545 (depend): Don't try to do "gcc expread.y".
1546 (expread.o): Update dependencies by hand.
1548 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1551 Fixed a variety of small typos that prevented info from formatting
1552 cleanly; altered too-long heading for GPL Appendix, as discussed
1553 w/RMS; Changed date on cover to July 91.
1555 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1558 (1) Applied some fixes due to comments from Larry Breed (easier ones
1559 through chapsec 5.2)
1560 (2) Eliminated use of @footnote---had my doubts about it anyways, and
1561 it's broken in latest texinfo
1562 (3) Introduced *some* use of [] for optional arguments, where
1563 explanation is not simpler by listing cmd w arg and cmd w/out arg
1564 separately. Still not using @deffn.
1565 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
1566 couple of headings are too long. Need patches to texinfo or revision
1569 * Partial update to README (which still needs work for this
1570 release!): (1) use of configure corrected for new script,
1571 (2) "make gdb.dvi" and "make gdb.info" mentioned.
1573 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
1575 * symtab.c (lookup_symbol): Don't complain right off about
1576 no debug symbols; use the misc function vector first.
1577 (list_symbols): Use misc function vector to find symbols
1578 that don't have debug info, and print them.
1579 (find_pc_symtab): Temporarily avoid fatal() when psymtab
1580 PC range doesn't match symtab PC range, as it does on the
1581 MIPS because our symtab reading isn't perfect.
1583 * dbxread.c (dbx_symfile_read): Make warning about
1584 "no debug symbols" slightly nicer.
1586 * source.c (select_source_symtab): If "main" symbol exists,
1587 but decode_line_spec can't find line info, don't just return
1588 a zero; try other source symtabs or give an error.
1590 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
1591 their low addresses first, then rip through fixing high addrs.
1593 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
1594 <runene@ifi.uio.no>.
1595 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
1597 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1599 * Minor, mostly mechanical, cleanup of doc subdir for clean
1600 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
1601 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
1603 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
1605 Mostly MIPS and general symbol-reading fixups.
1607 * doc/gdbint.texinfo: Add documentation on symbol-reading
1610 * mipsread.c: Remove kludges around #include "ecoff.h".
1611 Remove redefinitions of a_magic, etc, no longer used.
1612 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
1613 Fix global overview comments to match symfile.c protocol.
1614 (mipscoff_new_init): Eliminate cur_hdr if we have one.
1615 (mipscoff_symfile_read): Eliminate unused code. Avoid
1616 sorting all the symtabs, when all we have read here is psymtabs.
1617 The symtabs are sorted as they are created anyway. Tell
1618 condense_misc_bunches whether we're mainline.
1619 (psymtab_to_symtab_1): Pass filename when recursing, to make
1620 stack trace more informative.
1621 (parse_partial_symbols): Assume cur_hdr as argument.
1622 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
1623 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
1624 the TYPE_NAME of char *, since that's done in symfile.c.
1625 (free_numargs, parse_symbol, add_symbol, add_block,
1626 shrink_linetable): Declare these fns void.
1627 (upgrade_type): Convert tree of if's to switch. Clean up
1628 bogus "off == 0" handling with a complaint. Avoid setting
1629 field bitpos and bitsize of array with lower and upper bounds.
1630 Check specified bitsize of elements against their actual type's
1631 bitsize, and complain if different. Complain about unknown
1633 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
1634 (psymtab_to_symtab_1): Print names of subsidiary files that
1635 are being read in. FIXME, we read far too many files. This code
1636 is not the problem, the problem is in parse_fdr where the psymtabs
1638 (cross_ref): Result should indicate that we used one aux entry
1639 normally, or two if we encountered a "next" entry. This used
1640 to leave the caller pointing at the wrong aux entry.
1641 (add_symbol): If overflowed cur_block, reallocate it larger,
1642 chase all pointers to it, and complain(), rather than clobber memory.
1643 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
1644 (new_field): Only allocate one field initially, not two.
1645 Pull ++ out of macro argument. Simplify.
1646 (_initialize_mipsread): Avoid initialization of importd
1647 global_psymbols and static_psymbols.
1649 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
1650 to properly set pst->symtab; avoid searching for it.
1651 (symfile_fns): Improve comments, add a FIXME.
1652 * dbxread.c: Update comments to reflect symfile protocol.
1653 (read_ofile_symtab, end_symtab): Return the symtab.
1654 (psymtab_to_symtab_1): Set pst->symtab.
1656 * coffread.c (coff_symfile_read): tell condense_misc_bunches
1657 whether we're mainline.
1659 * symfile.h (sym_fns): Remove unused sym_discard member.
1660 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
1662 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
1663 the environment variable is not.
1664 * infcmd.c (finish_command): Use filtered printfs.
1665 * cplus-dem.c: Add struct tags to a few unnamed structs.
1666 * valops.c (value_coerce_array): Improve comments.
1667 * valprint.c (type_print_varspec_suffix): Print array size only
1668 if greater than zero.
1669 * m88k-tdep.c: Shift some lines left by one space, that had
1670 apparently been trashed at some point.
1671 * TODO: More things to do, a few got done.
1673 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1675 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
1676 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
1678 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
1679 * expread.y, findvar.c, symmisc.c: Ditto.
1680 * printcmd.c (address_info): Update printed forms of LOC_
1681 symbols. Elim LOC_EXTERNAL.
1682 (print_frame_args): Keep track of param stack offsets before
1683 re-looking up to find the local register param is kept in.
1685 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
1686 Further integration of mipsread into gdb. Eliminate unused
1687 routines, duplicate declarations. Handle static symbols in
1688 psymtabs as well as external symbols. When reading symtabs,
1689 insert symbols into the correct block (global, static, or a local
1691 (read_mips_symtab, parse_partial_symbols): Don't pass useless
1693 (mipscoff_symfile_read): Don't call select_source_symtab.
1694 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
1695 rather than SYMBOL_VALUE.
1696 (parse_external): Comment clobbering of top_stack.
1697 (parse_partial_symbols): Update comments. Allocate and parse
1698 static symbols as well as external symbols. FIXME, enum values
1699 are not handled in this pass, but should be. Inline new_psymbol.
1700 Use SYMBOL_VALUE_ADDRESS.
1701 (psymtab_to_symtab_1): Read symbols into global static block
1702 by default (until enter some function's local block context).
1703 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
1704 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
1706 * source.c (select_source_symtab): Select a source symtab
1707 from either the symtabs or, failing that, the psymtabs.
1708 (list_command): Update error message.
1709 (forward_search_command, reverse_search_command): Use getc, not
1710 fgetc, for speed. FIXME, add comment about buffers that die if
1711 overrun by long line.
1713 * values.c (unpack_field_as_long, modify_field): Avoid shifting
1714 by an entire word, which is not portable, if we have a 32-bit
1715 field. (Code in dbxread.c already turns such bitfields, if
1716 aligned, into ordinary ints, but fixing this will help for other
1717 symbol formats and for future changes.)
1718 * core.c (core_open): Handle ANSI const brain death.
1719 * utils.c (vprintf): Fix varargs typo.
1721 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1723 * findvar.c (find_var_value): Handle &function better.
1724 * TODO: Document work needed on &fn and &array.
1725 * printcmd.c (print_address_symbolic): New arg is the prefix
1726 to print if a name is printed.
1727 (print_address_demangle): Honor "set print address" now.
1728 Use new arg above to improve spacing of output.
1729 * valprint.c (val_print): When printing function pointers,
1730 print symbolic form too.
1731 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
1733 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1735 * core.c (memory_error): Reword error msg to mislead less.
1737 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
1739 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
1740 parse_partial_symbols): Use newer BFD internals (external_filehdr
1741 and external_aouthdr), byte-swap the fields that we care about
1742 before using them, and make the file header data local to
1743 read_the_mips_symtab rather than global.
1745 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
1747 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
1748 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
1750 * main.c (command_line_input): Flush stdout and stderr
1751 before every call to readline. This reportedly fixes a bug
1752 that comes up in Sys V running emacs-gdb and/or xxgdb,
1753 when stdin/out are pipes or sockets.
1755 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1757 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
1758 Avoid declaring Makefile dependencies, because GNU Make stupidly
1759 tries to update it if we do.
1761 * coffread.c: Revise for minor changes to bfd internal coff
1764 * configure: If -template= is given a relative path, make it
1765 absolute before recurring in subdirectories.
1767 * configure, configure.in, Makefile.in: Install "configure" script
1768 as replacement for config.gdb.
1769 * config.gdb, Makefile.dist, Makefile.sdir: Remove
1770 * README: Update for configure, mostly. FIXME.
1772 * Add dec3100 as equivalent to littlemips. Indicate in all host &
1773 target config files that they are for the host. When the lines
1774 get copied into the Makefile, this makes it more obvious what's
1777 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1779 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
1780 tabs, which end up in the disassembler output inadvertently.
1782 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1784 Make it compile cleanly in an ANSI GCC2 environment.
1786 * blockframe.c: <stdio.h>
1787 * cplus-dem.c: free takes a void *, ifdef __STDC__
1788 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
1790 * defs.h (alloca): Avoid doing anything if alloca already def'd.
1791 * stddef.h, stdlib.h: Remove these files.
1792 * symtab.c: Avoid declaring qsort, close.
1793 * symfile.c: Avoid declaring close.
1794 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
1795 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
1797 Assorted other changes.
1798 * dbxread.c: include "libaout.h", not "liba.out.h".
1799 * printcmd.c (print_frame_args): Set recurse properly for
1800 indentation of struct and array parameters.
1801 * valops.c (value_cast): Allow cast to void.
1802 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
1803 single_step() in a target-independent fashion.
1804 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
1805 set up to be ready to continue. This makes us target independent.
1806 * infptrace.c (child_resume): Remove call to single_step; now
1807 can single step a SPARC target of any kind.
1809 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1811 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
1812 docn into separate sections---basically chapters, plus two loose
1813 pieces that can be configured to go in different places. This
1814 allows GNU m4 to preprocess the manual without coredumping.
1816 * Makefile.dist: tell TeX where to find texinfo.
1818 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1820 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
1821 the new target "rdl-apps.texinfo" which captures the Makefile
1822 variable that records where to find the Readline libraries.
1824 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
1826 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
1827 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
1828 * defs.h (const, volatile): Only define if not already defined.
1829 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
1831 * README: Update for release 3.95.
1832 * config.gdb: Don't create readline dir in subdir builds.
1833 * main.c: Include with "..." form for non-system include files,
1834 so "gcc -MM" for "make depend" works.
1835 Include readline files with "...h" rather than <readline/...h>.
1836 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
1838 * coffread.c: Undo minor damage done by Rich Pixley. Use
1839 different internal and external representations of COFF
1840 data structures. Use new BFD routines for swapping them in and
1842 * symfile.c (free_named_symtabs): Avoid freeing file names that
1843 are null or empty. Old i960 tools seem to produce files that
1844 claim to have empty names, causing each successive file read
1845 to blow away the previous one.
1846 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
1847 Move deferred_stores to top of file, but don't separate its
1848 #define's from its variable. Add commentary.
1849 * Makefile.dist: Fix Rich damage; undo "configure" changes in
1850 favor of keeping the (working) config.gdb. Move readline
1853 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
1855 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
1857 * infptrace.c (fetch_registers): no result, since now void.
1858 * tconfig/news: target depends on m68k-tdep too.
1860 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1862 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
1865 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
1866 applied various small fixes due to or inspired by RMS comments
1868 * doc/gdb.texinfo: finished using all RMS comments, save those for
1869 appendices on readline and cmd history (which are in other source
1872 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1874 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
1875 chapter 9; (2) documented 'break' command's menu mode for
1876 overloaded names, in response to hgs problem report C++ p-31
1878 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1880 * doc/gdb.texinfo: (1) better introductory example; (2) more
1881 consistent use of @code, @samp, @file, @kbd throughout; small
1882 cleanups to first three nodes; (3) new "Contributors" node;
1883 (4) Appendix, Renamed Commands; (5) divert specialized startup
1884 instructions to "Targets" chapter for generic manuals, while
1885 leaving them up front for manuals specific to specialized
1886 environments; (6) apply fixes from RMS comments through chapter 4.
1888 * pretex.m4: modify explanatory text slightly (and redefine
1889 "regexp") to keep GNU m4 from complaining. (It still crashes
1890 later, but one step at a time...)
1892 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
1894 * readline/readline.c (update_line): Avoid dereferencing a pointer
1895 before comparing it to its bounds. Saber caught this.
1896 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
1897 and only set PC if tgetstr returned non-null. Saber caught this.
1899 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1901 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
1902 stuff for config manual) here where it counts; updated
1903 to use new subdir structure (gdb/doc/).
1905 * Makefile: generated from above via
1909 * gdbint.texinfo: added instructions on generating gdb.info* files
1910 locally for release. These are ordinary info
1911 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
1912 Makefile)---but due to use of texinfo 2, can't count on makeinfo
1913 to generate these, so we distribute them already formatted.
1915 * gdb.texinfo: included full Info node and menu crud (as generated
1916 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
1918 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
1919 put in comments-for-future gdb.info target (one day makeinfo will
1922 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1924 * gdb.texinfo: Updated to include new or old undocumented
1925 commands, at least the following (perhaps some others I forgot to
1926 record): info f, info float, info path, info program, info s, info
1927 set, info source, info terminal, info types, info user, set/show
1929 Also covered all recent GDB command renames for v4.
1931 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1933 * mipsread.c: Rather than keeping count of how many symtabs
1934 and psymtabs we have, for sorting purposes, count them when
1935 we need to sort. This fixes bug in rereading of symbol tables.
1937 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1939 * infcmd.c: renamed "info path" to "show paths"
1940 * gdbrc.tex: documented above.
1942 Wed May 8 04:51:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1944 * remote.c: Fix comments.
1945 * utils.c (error): Force out any pending wrap output.
1947 Sat May 4 11:11:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1949 * Makefile.dist: Roll VERSION to 3.95.
1950 Fix up "saber_gdb" to work again.
1951 * saber.suppress: Update.
1953 * coffread.c, exec.c, infptrace.c, inftarg.c, remote.c, solib.c,
1954 symtab.h, target.c, target.h: Lint.
1955 * core.c: setup and select frame after reading shared libs,
1956 else reading shared libs will clobber them. Lint.
1957 * utils.c (error): Force out any buffered wrap text.
1959 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1961 * remote.c: Remove decls of memory_insert_breakpoint
1962 and memory_remove_breakpoint, no longer used. (Suggestion of
1965 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
1966 to make it easier to interface to "configure"'d libraries.
1968 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
1970 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
1971 aliases for set/show print.
1973 Thu May 2 11:22:02 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
1975 * coffread.c (coff_sym_fns) [TDESC]: Make the type be m88kbcs.
1977 * m88k-tdep.c (IEEE_isNAN): New function.
1979 * infrun.c, m88k-tdep.c, m88k-xdep.c: Change

2453 infcmd.c: Add unset_command.
2454 (_initialize_infcmd): Add "unset" and use it for "unset env".
2456 * breakpoint.c (_initialize_breakpoint): Remove "unset".
2458 * valprint.c: Add "set/show print", {set,show}_print.
2459 Rename "set addressprint" to "set print address".
2460 Rename "set arrayprint" to "set print array".
2461 Rename "set array-max" to "set print elements".
2462 Rename "set prettyprint" to "set print pretty".
2463 Rename "set unionprint" to "set print union".
2464 Rename "set vtblprint" to "set print vtbl".
2466 * main.c: Rename version_info to show_version.
2467 (_initialize_main): Rename "info version" to "show version".
2469 * values.c: Rename value_history_info to show_values.
2470 (_initialize_values): Rename "info values" to "show values".
2472 Sun Apr 14 23:08:34 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
2474 * inftarg.c (child_open), remote-vx{,.68}.c (vx_proc_open):
2475 New function to give correct error message.
2477 Thu Apr 11 17:19:41 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
2479 * target.h: Add to_doc and target_preopen.
2480 target.c: Add target_preopen and target_command.
2482 (add_target): Call add_cmd and mess with targetlist->doc.
2483 core.c, exec.c, remote-eb.c, remote-nindy.c, remote-vx.c,
2484 remote-vx.68.c, inftarg.c, remote.c: Add doc field to target struct.
2485 Call target_preopen from open routine.
2487 * main.c: Rename editing_info to show_commands.
2488 (_initialize_main): Rename "info editing" to "show commands".
2490 * source.c: Rename directories_info to show_directories.
2491 (_initialize_values): Rename "info directories" to "show directories".
2493 * values.c: Rename convenience_info to show_convenience.
2494 (_initialize_values): Rename "info convenience" to "show convenience".
2496 * copying.awk (_initialize_copying): Rename "info copying" to
2497 "show copying" and "info warranty" to "show warranty".
2498 Rename {copying,warranty}_info to show_{copying,warranty}.
2500 * symfile.c: Rename add_syms_command to add_symbol_file_command.
2501 (_initialize_symfile, add_syms_addr_command):
2502 Rename add-syms to add-symbol-file.
2504 Thu Apr 18 18:08:30 1991 John Gilmore (gnu at cygint.cygnus.com)
2506 * symfile.h (free_named_symtabs): Rename from free_named_symtab.
2507 * symfile.c (clear_symtab_users_once, cashier_psymtab,
2508 free_named_symtabs): Move these routines from symmisc.c.
2509 * symmisc.c (same): same.
2510 (free_symtab): Make non-static.
2511 * symtab.h (free_symtab): Declare as exported void fn now.
2512 * dbxread.c (end_symtab, end_psymtab): Change comments.
2513 (initialize_dbxread): Call dbx_new_init() in case the first
2514 command is add-symbols.
2515 * target.c (dummy_target): Permit add_syms_addr_command.
2517 Sat Apr 13 14:46:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2519 Permit symbols to be superseded when new symbol files have
2520 been read in, particularly for VxWorks.
2522 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
2523 to the main file, as well as to include files. Also, put global
2524 functions into the global psymtab, to make "i fun" work.
2525 (end_psymtab): Free named symtabs and psymtabs for a file, once a
2526 new psymtab for it has been read.
2527 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
2528 a file, once a new symtab has been read for it.
2529 * mipsread.c: FIXME. We need to do the same for MIPS, but it
2530 looks harder to determine the top-level block before it's been
2531 queued to the psymtab list.
2533 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
2534 If we have wiped out any old symbol tables, clean up at end of
2536 (symbol_file_command): Don't reference symfile_fns if it's zero.
2538 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
2539 defines for the blocks of a blockvector that contain global and
2540 file-static symbols and the first of the smaller scope contours.
2541 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
2542 decode_line_1, make_symbol_completion_list): Use the above.
2543 * coffread.c (end_symtab, patch_opaque_types): Ditto.
2544 * dbxread.c (end_symtab): Ditto.
2545 * expread.y (block): Ditto.
2546 * mipsread.c (throughout): Ditto.
2547 * symmisc.c (free_named_symtabs): Ditto.
2549 * symtab.c (list_symbols): Process the first symbol of the
2550 static psymbols list.
2551 (types_info): Restore this function from its untimely #if 0.
2552 It's not perfect, but it is better than nothing.
2553 (_initialize_symtab): Restore "info types".
2555 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2557 * m68k-stub.c: Remote stub for 680x0's, created from
2558 rem-m68k.shar (which is removed).
2559 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
2560 Remove RCS log stuff now that we use CVS and it blows our diffs.
2562 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2564 * symmisc.c (free_named_symtab): Make it work, in its current
2565 kludgy fashion. Change result to indicate if we blew away bkpts.
2566 * dbxread.c (end_symtab): Accumulate result from
2567 free_named_symtab and print warning if we blew user's state.
2568 * symfile.h: free_named_symtab now returns an int.
2570 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
2572 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
2573 is the first symbol read, even if not mainline.
2574 (dbx_psymtab_to_symtab): symfile might be zero, cope.
2575 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
2576 (set_section_command): New command ("section xxx yyy" -- should
2577 be renamed to "set section xxx yyy" FIXME) which sets the
2578 base address of a section of the exec file, overriding the
2579 virtual address that BFD reports.
2581 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2583 * exec.c: Add add_syms_addr_command to exec_ops, so you can
2584 load symbols at any address while examining an exec file.
2586 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
2588 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
2589 for printing the float info is host-dependent, not
2590 target-dependent. FIXME.
2591 * i386-pinsn.c: Move #includes to top, remove useless ones.
2592 * i386-tdep.c: Don't bother including <.../reg.h> since we
2593 don't use it (and it doesn't exist on host systems).
2595 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
2596 Convert negative numbers properly.
2597 (ieee_test): Make numbers really random; fix format arg.
2599 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
2600 * core.c (core_detach): Unpush core_ops, which might not be on
2601 top. We used to just pop the top, which broke things. Don't
2602 need dont_repeat() any more.
2603 (core_file_command): Psst! Don't repeat it.
2604 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
2605 * expprint.c (print_subexp): Avoid switch fallthru on
2606 BINOP_ASSIGN_MODIFY, so we can print += and such.
2607 * frame.h: Fix typo.
2608 * inflow.c (kill_command): After killing inferior, print our
2609 current frame in the core file, if we have one.
2610 (generic_mourn_inferior): When inferior dies, either select
2611 the current frame (in the new target, e.g. core file), or
2612 set both the current and selected frames to NULL.
2614 Changes from Peter Schauer.
2616 * infptrace.c: Avoid <sys/ptrace.h> on USG.
2618 * Make all file names fit in 14 characters (sigh and damn!):
2619 mv hp300hpux-xdep.c hp300ux-xdep.c
2620 mv symmetry-xdep.c symm-xdep.c
2621 mv symmetry-tdep.c symm-tdep.c
2622 mv convex-opcode.h convx-opcode.h
2623 mv tm-vxworks960.h tm-vx960.h
2624 mv tm-vxworks68.h tm-vx68.h
2625 mv Makefile.srcdir Makefile.sdir
2626 mv gdb-int.texinfo gdbint.texinfo
2627 mv remote-sa.m68k.shar rem-m68k.shar
2628 mv remote-multi.shar rem-multi.shar
2629 * Makefile.dist, README, config.gdb, convex-pinsn.c,
2630 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
2631 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
2634 * command.c (user_info_1, user_info): New command for listing
2635 the user-defined commands.
2637 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
2639 * dbxread.c (really_free_pendings): Clear file_symbols
2640 and global_symbols after freeing them; otherwise, running
2641 this function twice (if it appears twice on the cleanup
2642 chain), we try to free things twice.
2644 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
2645 based on text_addr (the address of text in core), not on addr (the
2646 offset between text in the .o file and in core). This change
2647 is from Peter Schauer.
2649 * main.c: Define ALL_CLEANUPS as a cast of zero.
2650 (return_to_top_level): Use it.
2651 (main): Do all cleanups after each command run as part
2652 of the gdb startup sequence. Also do all cleanups before
2653 entering the command loop, and every time we exit the command
2654 loop and reenter. Before, the cleanups from the startup sequence
2655 were being left undone until the first error!
2656 (command_loop): Rename do_nothing cleanup to command_loop_marker
2657 so we can see it easily when examining the cleanup chain.
2658 (init_signals): Add another do_nothing for signal handling.
2659 (quit_command): Only try to kill target if it has execution.
2660 Problems in the target stack got us into a state where
2661 inferior_pid was nonzero but none of the targets had execution.
2662 In this state you couldn't exit gdb.
2664 * dbxread.c: Two changes from Peter Schauer.
2665 (echo_command): Fflush output after an echo command.
2666 (show_history): Pass all args to cmd_show_list.
2668 * utils.c (init_malloc): Call mtrace to turn on tracing
2669 if the environment variable MALLOC_TRACE is set to a file name.
2670 * mtrace.c: Add source file which provides a log of every malloc,
2671 free, and realloc to a trace file.
2672 * mtrace.awk: Add source file which analyzes the trace file.
2673 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
2674 (VERSION): Roll to 3.94.3.
2676 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
2677 (check_duplicates): Don't bother with watchpoints.
2678 (set_raw_breakpoint): Comment about danger of this routine.
2679 (watch_command): Parse and eval all args before calling
2682 * solib.c (find_solib): Avoid error in referencing memory to
2683 see if any more shared libraries have been added. This is
2684 particularly useful if the target has terminated. Bug reported
2687 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
2688 in bringing up 3.94.2 on the Sun-3.
2690 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
2691 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
2692 expression (in scope) before reenabling watchpoint.
2693 * signame.c (init_sigs): Add missing declaration of i, fix
2694 sys_siglist declaration.
2695 * source.c (list_command): Fixed range computation to use
2697 * stack.c (backtrace_command): Do not allow command if target has
2698 no stack, print informative error message.
2699 * target.c (target_command): Do not write into command line
2700 because this fails if the target command is used in a user defined
2701 command. [This change was enhanced by gnu to support any-
2702 unique-prefix matching on target names.]
2703 * valops.c (value_struct_elt): Avoid infinite loop on an
2704 erroneous attempt to print the member of function (try p main.p).
2706 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
2708 * expread.y (name_no_typename): Avoid reduce/reduce errors
2709 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
2710 Since the GDB parser really doesn't use name_no_typename in a
2711 name-only context, the parser can't tell the diff between
2712 names and numbers here. Avoid allowing a name_no_typename
2713 to be a NAME_OR_*INT to resolve the conflict.
2715 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2717 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
2719 * valprint.c (val_print_fields): bitfield printing didn't handle
2720 byte order. Indirect through a few more fns to cope.
2722 * values.c (modify_field): also cope with byte order.
2724 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2726 Cleanup for release 3.94.2:
2728 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
2729 include files. Roll version to 3.94.2.
2731 * coffread.c (init_stringtab): Read length into unsigned char
2732 array before swapping; don't assume 32-bit longs.
2734 * target.c (target_info): Don't bother with get_sym_file, just use
2735 the symfile global variable.
2736 * symtab.h, symfile.c (get_sym_file): Delete it.
2738 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
2739 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
2740 (read_type): Replace one more error() with complain().
2742 * mipsread.c (parse_partial_symbols): Replace printf with complain.
2744 * i960-tdep.c: Fix copyright attribution.
2746 * config.gdb: Quote all backquotes in doublequotes. You can
2747 quote me on that. BSD 4.4 shell found this one.
2749 * infptrace.c (throughout): The third argument to ptrace is an
2752 * infrun.c (wait_for_inferior): When program has terminated, we
2753 have to call target_terminal_ours before we pop that target off
2754 the stack (e.g. before a call to target_kill or
2755 target_mourn_inferior). This fixes problem where a program
2756 terminates, then GDB stops for (tty output) and you have to type
2757 "fg" to the shell to resume it. FIXME: This code for what to
2758 do after termination really should be in normal_stop instead.
2760 * gdbcore.h (read_memory_check): Change declaration; it changed
2763 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
2764 4.4 prereleases, this avoids a bug in their sgtty compatability
2766 * remote.c: Use terminal.h rather than hand-rolling the same.
2768 * signame.c, signame.h (psignal): Arg is unsigned, not int.
2769 * utils.c (strsave, strstr): Fix arg types.
2770 * valprint.c (val_print): lint
2772 MIPS symbol table support from Per Bothner:
2774 * symfile.c (symtab_fns): Remove initializer table that needs to
2775 be hacked for each new symbol file format supported.
2776 (add_symtab_fns): New function, chains symbol table
2777 handlers into the global list.
2778 (symfile_init): Search this list.
2779 * symfile.h: Add next pointer, declare add_symtab_fns.
2780 * coffread.c (_initialize_coffread): Call add_symtab_fns.
2781 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
2783 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
2784 symbol *). Thus, we no longer need the hack to trash
2785 pst->filename. Good, since that hack confused code in symfile.c!
2787 (reorder_symtabs, destroy_all_symtabs): Removed static
2788 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
2789 Instead, the latter now uses a temporary array (stack-allocated
2790 from an obstack, and then freed).
2792 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
2793 haven't been set in the outermost stBlock of a procedure. This was
2794 a problem with f77 binaries on Ultrix 4.?.
2796 (new_symtab, new_symbol, new_type): Continue changing code to use
2797 obstacks more and otherwise conform to dbxread internal style.
2798 Made the free_code of symtabs be free_linetable (as in dbxread)
2799 instead of free_contents. This implies memory leaks when reading
2800 a new symbol table, until the conversion is finished. Did change
2801 (struct symbol) and (struct type) to be allocated on the
2802 symbol_obstack. Blocks and blockvectors are among the things
2805 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
2806 tested much, but it solved one problem (reported by Meissner), and
2807 cleans up some other things. The problem happened when an
2808 included file contains actual code (functions) and not just
2809 definitions. The mips coff is a little inconvenient there, since
2810 it may cause a procedure to be mapped to the wrong psymtab.
2812 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
2813 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
2814 this will need work for the new core paradigm.
2816 Opcode patches from the net:
2818 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
2819 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
2820 missing altogether - they are added here. From Bruce Bauman.
2821 * mips-opcode.h: The low mask for C0 instructions was too small.
2822 From Garrett Lau. I modified the fix to check the entire 32-bit
2825 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
2828 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2830 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
2832 * dbxread.c (read_type): Pointer subtraction (value_sub in
2833 valarith.c) sometimes failed because the types of the
2834 pointers being subtracted were not identical.
2835 These differed because dbxread.c was allocating pointer types
2836 using dbx_alloc_type+smash_to_pointer_type instead of
2837 lookup_pointer_type. I failed to find a justification for the
2838 former, so I changed it to use the latter. Similarly, I
2839 replaced smash_to_function_type by lookup_function_type,
2840 and smash_to_reference_type by lookup_reference_type.
2842 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
2843 _initialize_mipsread): corresponding changes.
2845 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
2847 * source.c (mod_path): Do tilde_expand on each component of the path,
2848 rather than on the (list of) paths as a whole.
2849 (print_source_lines): Set first_line_listed in addition to
2850 current_source_symtab and current_source_line. If the source was
2851 not findable, after a "dir" command to fix the problem,
2852 a "list" would get the wrong lines.
2854 While I was there... (gnu):
2856 * dbxread.c (read_type): Change error to complaint.
2858 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2860 First attempt at detailed understanding of symbol table memory alloc.
2862 * dbxread.c (dbx_symfile_read): Free our string table if we
2863 aren't the mainline. Free the "info" struct since we're done with
2865 (init_psymbol_list): Free any previously allocated psymbol lists.
2866 (): FIXME: Should realloc-down the psymbol lists when done reading
2867 the main symbol file?
2869 * symmisc.c (free_symtab): Free fullname field too.
2871 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
2872 (REGISTER_ADDR): Make result type unsigned int.
2874 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
2875 define REGEX must also define REGEX1 (its dependency).
2877 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
2879 * tconfig/i960: No longer works, points you at vxworks960 or
2882 * xgdb.c, XGDB-README: Remove file. Users can get the much
2884 * Makefile.dist: Remove all trace of xgdb.
2886 * breakpoint.c (breakpoint_1): Pass demangle arg to
2887 print_address_symbolic.
2888 (clear_breakpoints): Remove unused function.
2889 (breakpoint_re_set_one): Guts of breakpoint_re_set.
2890 (breakpoint_re_set): Use catch_errors to do them all anyway.
2892 * gdb-int.texinfo (Host versus Target): Add section on what is
2893 a "host" feature versus what is a "target" feature.
2895 * infcmd.c (path_command, path_info): Handle the PATH variable
2896 (object search path) as conveniently as the source search path.
2897 * environ.c (set_in_environ): Set some vars in GDB's environment,
2898 in addition to the child's. PATH, G960BASE, G960BIN for starters.
2899 * source.c (mod_path): New function, from guts of
2900 directory_command, modifies a path. Used by path_command.
2901 (directory_command): Call it.
2902 * defs.h (strsave): Declare.
2904 * utils.c (sevenbit_strings): Add new printing option.
2905 (printchar): Use it.
2906 (strsave): Provide this handy helper routine.
2907 (set_width_command): Rename set_screen_width_command.
2908 (_initialize_utils): "set screen-width" => "set width";
2909 "set screen-height" => "set height"; add sevenbit-strings.
2911 * infcmd.c (do_registers_info): Print floating point registers
2912 in raw hex as well as float format, regardless of whether it is
2913 a "virtual" convertible register.
2914 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
2915 regs as a double, just in case it's being used that way.
2916 * values.c (unpack_long): Comment on array/function coercion.
2917 (unpack_double): Argument is in target byte order now. For
2918 integer arguments, just call unpack_long and float the result.
2919 * m68k-tdep.c: include defs.h for "const" handling.
2920 * remote-nindy.c: Use ieee-float stuff.
2921 (nindy_fetch_registers): Unpack double regs to host double, then
2923 (nindy_store_registers): Pack extendeds to host double, flip
2924 around by misusing unpack_double, send as target double.
2926 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
2927 zero, as when stopped at the first instruction of a process.
2929 * blockframe.c: Fix filename in comment (param.h => tm.h).
2930 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
2931 * tm-68k.h: Fix typos.
2933 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
2935 Changes from a bringup on the DEC Vax under Ultrix 4.0.
2937 * coredep.c (fetch_core_registers): Pass end-address of register
2938 section to register_addr as expected. Don't call supply_register
2939 if we'd just pass it garbage.
2941 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
2943 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.

2948 * stack.c (print_frame_info): Identify source file & line
2949 even if we can't print it.
2951 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
2953 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
2955 Clean up IEEE floating point support.
2957 * ieee-float.h: New file.

2967 * m68k-tdep.c: Define ext_format_68881.
2968 * sparc-tdep.c: Define ext_format_sparc, though unused.
2969 * Makefile.dist (HFILES): Add ieee-float.h.
2970 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT

2975 * nindy-share/coffstrip.c: Remove file.
2976 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
2977 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
2978 * tconfig/nindy960: Remove reference to coffstrip.o.
2980 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
2982 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
2984 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
2985 * dbxread.c: Remove static symfile_bfd.
2986 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
2988 * inftarg.c (child_detach): Pop the child_ops vector if the
2989 detach is successful.
2990 * remote-nindy.c (nindy_create_inferior): Don't push a new
2991 nindy_ops since nindy uses the same one for execution and memory
2993 * core.c (core_ops): Use child_attach and child_create_inferior
2994 rather than default attach and create_inferior functions.
2996 Handle floating point registers in core files.
2998 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
2999 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
3000 This version untested since BFD doesn't yet support sun3 core
3002 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
3003 conventions. Fix comments and style. This version has not
3004 been compiled yet, since we have no HP inhouse.
3005 * core.c (get_core_registers): Look for two sections, ".reg"
3006 and ".reg2", and pass both to fetch_core_registers sequentially.
3008 Revise directory path yet again.
3010 * source.c (forget_cached_source_info): Not static any more.
3011 (init_source_path): New default source path is "$cdir:$cwd".
3012 (dir_command): Handle variable arguments ($cdir, $cwd).
3013 (source_info): Print "Compilation directory" rather than
3014 "Originally compiled in" to remind people of $cdir.
3015 (openp): If the path contains $cwd, use current directory.
3016 (open_source_file): If compilation directory is known, replace
3017 first $cdir in path with the compilation directory.
3018 (print_source_lines): Even if we can't print the lines, set the
3019 current symtab and line for future commands like "info source" or
3020 "breakpoint". Also, error message now contains the file name,
3021 line number, and file access error message.
3022 (_initialize_source): Fix help text to describe changes.
3023 * main.c (cd_command): Forget cached source info when we chdir.
3024 * utils.c (strstr): Add simple implementation.
3026 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
3028 * coffread.c (read_one_sym, init_linetable, init_stringtab):
3029 Byte-swap COFF symbol tables if necessary when reading them in.
3030 Use complain() to replace error message in one spot. Needs
3031 corresponding change in bfd/coff-code.h to make some symbol
3032 swapping routines non-static.
3034 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3036 Merge changes from Eirik Fuller, for UTek.

3044 declarations of errno.
3046 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
3048 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
3049 <rpc/rpc.h> and <rpc/types.h>.
3051 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
3053 * i960-tdep.c (examine_prologue): Add new argument limit,
3054 which stops the scan at the end of the prologue, or at the PC.
3055 This fixes a problem where it walks down into the code for the
3056 user's statements if that code looks like function prologues.
3057 Mark Fox and I have been bouncing this code back and forth, making
3058 small changes to it. Callers changed to match.
3060 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
3062 Cleanup for gdb-3.94 release final:
3064 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
3065 the .c files from vx-share and nindy-share, from the various
3066 macros, since they are not found via ALLDEPFILES.
3067 (SFILES): Add tm-i960.h.
3068 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
3069 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
3071 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
3072 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.

3076 * am29k-tdep.c: Add contribution line.
3077 (examine_prologue): Cache information about function prologues in
3078 the misc-function-vector to avoid lots of references over the
3079 serial line while examining instructions.
3081 * core.c (core_close): New function made from cleanup_core.
3083 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
3084 remote-vx.c, remote.c, target.c, target.h,
3085 Update target_ops vector to add attach, close, and load entries.
3086 Use add_syms_addr_command, not add_file_addr_command, for
3087 add_file. Break out close routine from existing code.
3089 * dbxread.c (really_free_pendings): Don't free pending_blocks;
3090 they are in an obstack.
3091 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
3093 (define_symbol): Add symbol type parameter; change callers;
3094 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
3095 it to influence the symbol class on the i960.
3096 (define_symbol): Swap LOC_CONST's into target byte order.
3098 * exec.c (exec_close): New function.
3099 (exec_file_command): Call it.
3101 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
3102 Fix byte order of frame pointer.
3103 (read_var_value): Result of 0 if var's value can't be found,
3104 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
3105 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
3106 (locate_var_value): Use read_var_value and use its lazy address
3107 as the location of the var's value. Lint.
3109 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
3112 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
3113 obsolete Intel versions in favor of vxgdb versions.
3114 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
3115 code dealing with byte order of values, which Intel did in host byte
3116 order rather than gdb-4's target byte order.
3117 (i960_frame_chain_valid): Move to nindy-tdep.c.
3118 (examine_prologue, skip_prologue, frame_find_saved_regs,
3119 frame_args_address, leafproc_return, saved_pc_after_call,
3120 pop_frame): Add vxgdb versions from Mark Fox.
3121 (examine_prologue, frame_struct_result_address): Add code
3122 to deal with the saved value of G13 (struct return address
3124 (frame_args_address): Modify Mark's version to prefer the
3125 saved value over the current value in the topmost frame.
3126 Cache result in the frame info to avoid performance hair in
3128 (print_fault): Add gdb960 code for printing faults.
3129 (_initialize_i960): Actually call check_host.
3131 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
3132 add stub routines. FIXME, these currently just return zero!
3134 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
3135 (attach_command): Call target_attach, not target_open, now.
3137 * infrun.c (normal_stop): Make global, not static, for vx_attach.
3138 (child_attach): Rename from child_open.
3139 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
3140 don't confuse it with a zero step_resume_break_address.
3142 * inftarg.c (child_detach): Eliminate inferior_pid test.
3143 (child_files_info): Clean up message a bit.
3144 (child_ops): Use child_attach, not child_open, to attach.
3146 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
3147 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
3148 findvar.c to here, since it depends on the contents of the
3149 shadow_contents of breakpoints, but keep if #if 0 since it is
3152 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
3155 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
3156 (ptype_command, display_command): Eliminate have_inferior_p and
3157 have_core_file_p in favor of target_has_stack or
3158 target_has_execution.
3159 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
3160 code for actually finding the values of arguments, though we still
3161 keep track of the maximum stack offset for use in printing unnamed
3162 arguments. Handle missing FRAME_ARGS_ADDRESS.
3164 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
3165 (struct nindy_regs): Define registers passed to/from nindy.
3166 (nindy_fetch_registers, nindy_store-registers): Translate between
3167 nindy and GDB formats for the registers.
3168 (dcache_init): Statically allocate the cache, since it was being
3169 allocated by a malloc that was never freed anyway.
3170 (nindy_create_inferior): Error, not core dump, if no exec file.
3171 (nindy_before_main_loop): Use target_load, not target_add_file.
3173 * remote-vx.c (net_load): Specify large timeout for load
3174 requests. Allow user to break out with INTERRUPT.
3175 (net_break): Remove useless code, clean up. Change callers.
3176 (parse-args, skip_white_space, find_white_space): Clean up arg
3177 parsing to cope with quoted strings.
3178 (net_wait, net_quit): Never call error, just return status.
3179 (vx_read_register, vx_write_register): Cleanup status checking.
3180 #ifdef the code based on which CPU we are using (960 or 68k),
3181 FIXME, this should be completely general but it isn't yet.
3182 (vx_xfer_memory, vx_resume): Cleanup status checking.
3183 (vx_run_files_info): Improve message.
3184 (vx_load_command): Renamed from vx_add_file_command. Allow load
3186 (net_ptrace): Remove unused routine.
3187 (vx_wait): Adopt code from vxgdb960 to cope with broken
3188 connections to target machine and prompt to disconnect. Remove
3189 debug printouts. Map some EVENT_'s to SIGnals.
3190 (add_symbol_stub, vx_open): Print names of object files we found,
3191 and "ok" if we read their symbols OK. Clarify output in general.
3192 (vx_attach, vx_detach, vx_kill): Add these commands.
3193 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
3194 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
3195 "info files" output, and create_inferior, since we already have
3198 * stack.c (frame_info): Replace Frame_unknown with 0.
3199 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
3200 (return_command): Pop until the PC matches as well as the FP,
3201 so it works even if the FP is shared with another function,
3202 as in "frameless" or "leaf" procedures.
3204 * symfile.c (load_command): renamed from add_file_target_command.
3205 (add_syms_addr_command): renamed from add_file_addr_command.
3206 (add_syms_command): Stub to call target_add_syms.
3207 (_initialize_symfile): Change command names and descriptions,
3208 add-file => add-syms, and load from alias to its own command.
3210 * target.c (kill_or_be_killed, maybe_kill_then_attach,
3211 maybe_kill_then_create_inferior): Default for attempts to start
3212 a process, if one is already running, is to ask about killing
3213 it and retry if yes.
3214 (upstack_create_inferior): #if-0 it, strata obsolete it.
3215 (push_target, unpush_target, pop_target): to_close() a target
3216 before unstacking it.
3217 (target_info): Renamed from target_files_info.
3218 (_initialize_targets): Rename "i files" as "i target", accessible
3221 * target.h: Improve comments about the target_ vectored routines.
3223 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
3224 Convert commenting style to standard GNU style.
3225 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
3226 (SKIP_PROLOGUE): No longer a no-op.
3227 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
3228 (*_REGNUM): Sort register numbers.
3229 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
3230 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
3231 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
3232 are now 10 byte extendeds, not 8 byte doubles.
3233 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
3234 for nindy versus vxworks targets. FIXME, this should possibly go
3235 in the target vector.
3236 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
3237 frame_saved_regs and arg pointer with each frame.
3238 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
3239 (FRAME_ARGS_ADDRESS): Use cached result.
3240 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
3241 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
3242 (PRINT_RAMDON_SIGNAL): Call print_fault.
3243 (POP_FRAME): Now works.
3245 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
3246 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
3247 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
3248 (ADDITIONAL_OPTION_HANDLER): use target_load, not
3251 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
3252 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
3254 * valarith.c (value_subscripted_rvalue): Avoid handling
3255 floats and doubles specially; it gave alignment errors. Lint.
3257 * valops.c (value_of_variable, value_of_this): Error if unknown
3260 * valprint.c (print_floating): Bcopy rather than pointer-deref,
3261 to avoid alignment problems.
3262 (value_print): Handle unknown value address.
3263 (cplus_val_print): Two args are ignored; remove them. Change caller.
3264 (val_print): Use unpack_long rather than pointer-deref.
3267 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
3268 to avoid alignment problems.
3269 (value_being_returned): Error if return value unknown.
3270 (set_return_value): Add bogosity warning, FIXME. *
3272 * TODO: A woman's work is never done.
3274 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
3275 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
3276 Add ieee-float.o to OBS.
3277 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
3278 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
3279 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
3281 Changes to generalize the VxWorks RPC protocol slightly, to handle
3282 i960 as well as 68000.
3284 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
3285 * vx-share/reg.h: Produce i960 regs #ifdef I80960
3286 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
3287 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
3288 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
3289 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
3290 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
3291 so they will move in target byte order rather than network
3292 byte order (happens to be the same).
3294 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
3296 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
3298 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
3301 Add contribution lines to various files, showing where they
3304 * breakpoint.c (break_insn, check_break_insn_size,
3305 read_memory_nobpt): Remove to mem-break.c.
3307 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
3310 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
3311 entry has bad register number. This change is not
3312 tested in this release, FIXME.
3314 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
3317 * value.h: Force value's contents field to be aligned to hold
3318 at least a double or a long long (if supported). This avoids
3319 doing bcopy's in and out of the contents field.
3321 (step_1): Avoid coredump under obscure circumstances when we
3324 * symtab.h (misc_info): Add field to misc function vector for
3325 any kind of cached information the target code desires. AMD
3326 29000 uses this to avoid repeating examine_function_prologue's.
3328 * coffread.c: Lint. Remove static symfile, read_section_header.
3329 core.c (have_core_file_p): Lint: remove.
3330 expprint.c (print_subexp): Lint.
3331 infptrace.c, valops.c, valprint.c: lint.
3333 Roll in changes from vxgdb-5.0.1:
3335 * symtab.h: Comment byte order of each address class. Add
3336 LOC_LOCAL_ARG for frame-relative args (960).
3337 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
3338 symtab.c, symmisc.c: ditto.
3340 * infrun.c (init_wait_for_inferior): Clear stop_signal.
3342 * remote.c (remote_resume): Error if resume with a signal.
3344 * symfile.c (prim_record_misc_function): Clear misc_info.
3345 (fill_in_vptr_fieldno): Check stub type of arg.
3347 * valops.c (value_cast): Avoid looking up names of types whose
3348 name we don't know, to prevent coredump. Sun CC produces typedef
3349 rtx and the name of *rtx is zero...
3351 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3353 Roll in changes from final AMD 29000 port (Tiemann).
3355 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
3356 for ../include/a.out.encap.h. This might not work now that BFD
3357 is separately compiled. Instead, BFD support for encap will have
3358 to translate machine type 29k into the right COFF_MAGIC.
3360 * infcmd.c: Remove references to inferior_pid that aren't used
3361 in actual ptrace calls; use target_has_execution, etc.
3362 (have_inferior_p): Remove function.
3363 (program_info): Print target info rather than "process number";
3364 avoid gratuitous messages unless from_tty.
3365 (run_stack_dummy, finish_command): Set proceed_to_finish.
3366 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
3367 main.c: Lint. Lose have_inferior_p().
3368 inferior.h (have_inferior_p): Remove, lint.
3369 (proceed_to_finish): Add flag to ask that all regs be saved
3370 by normal_stop, for the few commands that need it, speeding up
3371 serial I/O. Add comments to stop_registers.
3373 * remote-eb.c: Remove newline from breakpoint message we grep
3374 for. Never time out when running the user program.
3378 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3380 Roll in changes from vxgdb-5.0.1:
3382 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
3383 symbol in its raw form, we are processing an unlinked ".o" file.
3384 See if the target environment has assigned it an address, using
3385 target_lookup_symbol (VxWorks does), and enter it into the symtab
3388 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
3389 68k versions for a simpler version that assumes zero FP at bottom.
3390 Fixes bug of truncated stack reports.
3392 * target.h (target_lookup_symbol): Define this routine's args
3393 and result, finally.
3395 * target.c (nosymbol): Default routine for target_lookup_symbol.
3396 (target_default): Default lookup_symbol and call_function too.
3397 (files_info): Only print has_all_memory warning if a non-dummy
3400 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
3401 vx_convert_from_virtual): If target does not have floating point,
3402 zero register "values", and avoid doing cross-net conversions.
3403 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
3404 (vx_open): Rearrange code that attaches to target and reads
3405 symbols for all loaded modules, to work if some of the modules
3406 are not accessible. Add symbol_stub() and add_symbol_stub()
3407 as callbacks from catch_errors(). Allow connect attempt to be
3408 interrupted painlessly with ^C (FIXME, there are still some bugs
3409 if the interrupt happens during symbol reading.). Print
3410 final message with puts_filtered, since symbol messages are
3415 * main.c (catch_errors): Only print errstring if non-null.
3416 (command_loop): Avoid an ioctl per command to test ISATTY.
3418 * remote-vx.c (net_load): make static; avoid sophomoric msg.
3419 (vx_xfer_memory): Return correct result!
3420 (vx_files_info): Indicate whether target has float or not.
3421 (vx_lookup_symbol): Complain, not error, if target gone.
3422 (vx_open): Print "Connected" msg before disabling immediate-quit.
3423 [FIXME: lookup_symbol and vx_open changes need testing.]
3425 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
3426 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
3427 contributor lines and update copyrights to 1991.
3429 Changes from an attempted H-PUX host port:
3431 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
3432 defines PT_ATTACH and PT_DETACH but not PT_KILL.
3433 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
3434 * remote-vx.c: include <sys/time.h> for HPUX.
3435 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
3436 "core_file_command" routine to BFD regime. May not work yet.
3438 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
3440 * xgdb.c: Replace X10 version with some VJ version.
3441 (FIXME: Its copyright assignment is not on record.)
3442 * xgdb.c: Update include files to X11R4 (Xaw crud).
3443 (xgdb_display_source, create_text_widget): fix call to
3444 get_filename_and_charpos. Rewack source window stuff for X11R4
3445 (gleaned from include files, and "nm's" of binary libraries, since
3446 I had no doc available).
3447 (append_selection, append_selection_word): Disable with FIXME
3448 since R4 changed interface here.
3449 (create_buttons): Add back the old set of buttons.
3450 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
3452 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
3453 Roll VERSION to 3.94 (not yet final though).
3455 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3457 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
3458 obstack_int_grow, obstack_int_grow_fast): Eliminate
3459 cast on left of assignment, which gives MIPS cc fits and is
3462 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
3463 F_ALIAS. Use printf, not fprintf, when not passing a file
3465 (compare_opcodes): Check that identical instructions have
3466 identical opcodes, complain otherwise.
3468 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
3469 was reported by Roland McGrath.
3470 (unimp): Only match if exactly zero instruction. (Roland)
3471 (branches and traps): Generate all variations of these
3472 instructions with macros, based on a single call that defines
3473 each condition name and its binary representation.
3474 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
3476 * valprint.c (val_print_fields): Take, and use, format parameter.
3477 This means that "p/x struct" again prints the elements in the
3478 desired format. Changed callers.
3480 * stack.c (frame_info): Use filtered output, and indicate wrap
3481 points. Remove kludgy formatting designed to avoid line wrap.
3483 * utils.c (wrap_here): If the line is already full (because
3484 we had printed a long indent or long wrapped string), do an
3485 immediate newline-and-indent.
3487 * m68k-pinsn.c (print_insn_arg): Bugfix from
3488 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
3489 instruction is incorrectly disassembled as bkpt #8.
3491 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
3492 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
3493 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
3494 and then will dump core (sometimes). I traced it back to an
3495 uninitialized symfile_name in psymtab_to_symtab.
3496 (const_vol_complaint): Add quotes to message.
3497 (define_symbol): Only believe line number if gcc_compiled.
3498 Avoid allocating symbol if we will not return it.
3500 Add target strata support so that newly established targets go
3501 into their right place in the target stack (e.g. a new exec file
3502 doesn't wipe out the ability to access the running process).
3504 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
3505 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
3506 and initialize it properly in all the targets.
3508 * target.h: Document strata. Change return type of push_target.
3510 * target.c (nomemory): new function for dummy memory access.
3511 (tcomplain): Rename complain, now also used in symfile.c.
3512 (push_target): Push targets within strata. New return value shows
3513 whether new target is on top of stack or not. Always keep dummy
3515 (target_files_info): Ignore dummy target.
3517 * core.c (core_open): Warn user, and skip accessing file, if the
3518 core target is not the topmost target in the stack.
3519 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
3522 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
3523 target_ops, it doesn't belong there since we have no regs there.
3524 Change name of target from machine => memory to clarify.
3526 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
3528 * Freeze version 3.93 for release.
3530 * Makefile.dist: Handle vx-share and nindy-share subdirs
3531 properly when building gdb.tar.Z.
3533 * symtab.c: lint; add no_symtab_msg to consolidate the messages
3534 printed in various places, so I could change just one copy.
3536 * dbxread.c, coffread.c: Change references to bfd->iostream
3537 to cast to FILE *, now that BFD avoids needing types defined
3538 in other header files.
3540 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3542 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
3543 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
3544 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
3545 (actually gcc -Wall).
3547 * dbxread.c: Remove first_global_sym, last_global_sym, since
3548 they are never referenced.
3550 * defs.h (baud_rate): Declare.
3551 main.c: Define it, and add the -b option to set it.
3553 * gdb-int.texinfo: Add text on how to define a new host or target
3554 architecture, prompted by Per Bothner's questions about MIPS
3557 * gdb.texinfo: Document "complaints". Change doc of -q since
3558 gdb no longer prints the copyright and blurb if you specify a file
3559 name to be debugged (just like Emacs). Add doc for Nindy-specific
3560 command line flags for specifying target serial port and such.
3561 Update copyright to 1991.
3563 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
3564 has taken over for us the job of ripping up executable files. The
3565 crud caused Per Bothner's port to not compile.
3567 * infrun.c (normal_stop): Avoid printing "Program exited
3568 normally" if we are in batch mode. This allows a GDB which
3569 executes a program on a target system, to behave like a Unix
3570 command (input from stdin, output to stdout, no extraneous
3573 * main.c (main): Allow additional machine-dependent command line
3574 options to be specified with the ADDITIONAL_OPTIONS,
3575 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
3576 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
3577 processing to occur just before the main loop with
3578 BEFORE_MAIN_LOOP_HOOK.
3579 (main): If a "core file" argument is specified, and it is not a
3580 core file, try it as a process ID to attach.
3581 (symbol_completion_function): Attempt to cope with
3582 "show screen-" TAB, not very successfully. This needs more work,
3584 (batch_file): New function, returns whether we are reading
3585 commands from an interactive tty on stdin, or from somewhere else.
3586 Called by normal_stop since it doesn't get from_tty passed down
3587 to it like many commands do.
3589 * remote-nindy.c: Handle command line options for nindy
3591 (nindy_before_main_loop): Prompt user for tty name if they
3592 don't specify it before getting to the interactive command loop.
3594 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
3595 and -r command line options. Also add hook before main loop
3596 to make it easy to specify a tty.
3598 * TODO: More things to do, one done.
3600 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
3602 * dbxread.c: Make complaint() calls pass pointer, not struct.
3603 Add complaints about badly formatted C++ type information
3604 (const/volatile indicator, and parse errors resulting in
3605 error_type). Fix C++ virtual member fn comment.
3606 (read_struct_type): Avoid bumping pointer if we got a parse
3607 error; this prevents our walking beyond the end of a string.
3608 Terminate loop on null char as well as semicolon.
3609 (process_one_symbol): Fix the LBRAC fix so that it uses the
3610 last previous SLINE, FUN, or SO record's PC address. C++ debug
3611 symbols did not have SLINE records in a useful order compared
3612 to the LBRAC records.
3613 (define_symbol): Handle "catch" records.
3615 * symtab.c (check_stub_type): Added new complain
3616 `stub_noname_complain' and added a consistency check to
3617 keep the debugger from crashing when finishing from an
3618 exception frame. A real fix will be needed later.
3620 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
3622 * infcmd.c (attach_command): Make global.
3624 * Makefile.dist (REMOTE_OBS): Make these compile by default,
3625 but make them easy to comment out. Perhaps later they should
3626 be enabled by what CPU you configure for? FIXME.
3627 (VERSION): Roll to 3.93.
3628 (pinsn.o): Remove rule for obsolete file.
3629 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
3631 Run down a problem that manifested by printing the wrong function
3632 name in stack traces of read_ofile_symtab. Turned out that the
3633 problem was the SunOS 4.1.1 (and previous) C compiler outputs
3634 the LBRAC symbol with an address in the *data* segment, which
3635 blew our binary search through the blocks.
3637 * dbxread.c: Use the complain() facility consistently to bitch
3638 about problems in the symbol file we are reading.
3639 (finish_block): Add code to check the nesting of the blocks;
3640 complain and Procrust them to fit if wrong.
3641 (make_blockvector): Check the order of the blocks, complain
3642 [but don't cope] if wrong.
3643 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
3644 symbols to be sure their PC value is greater than the last SLINE
3645 (line number) symbol we've seen, complaining and adopting the
3646 SLINE PC value if wrong.
3648 * symfile.h (struct complaint, complaint_root, complain,
3649 clear_complaints): Add.
3650 * symfile.c (complain, complaint_root, clear_complaints): Add
3651 facility to deal with non-fatal complaints and to regularize their
3653 (symbol_file_add): Clear complaint counters to allow new complaints.
3654 (initialize_symfile): Add 'set complaints' and 'show complaints'.
3656 * dbxread.c (dbx_symfile_read): Remember the address and size
3657 of the string table for the main symbol file, so we won't read it
3659 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
3660 to avoid reading the string table yet again. Lint.
3661 (throughout): Improve filtered output, including word wrap.
3662 (read_range_type): Improve Bothner's fix to handle other types too.
3664 * utils.c: Improve line wrap implementation. Handle unlimited
3665 width by making chars_per_line unsigned.
3666 (puts_filtered): New, easy, function.
3668 * defs.h (puts_filtered): add.
3670 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
3671 call the identical sort_symtab_syms() in symfile.c instead.
3673 * expread.y: Suggest the `file' command rather than `symbol-file'.
3675 * command.h (enum var_types): Add zinteger for seroable
3677 * command.c (do_setshow_command): Handle var_zinteger. Restructure
3678 nested if's into a switch.
3680 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
3681 we did not stop because of a breakpoint (it must have been for
3682 some other reason, like a "stepi"), so don't print anything.
3684 * symtab.c: Include <sys/types.h> all the time. Now that BFD
3685 doesn't include <sys/types.h>, old SunOS's require it for
3688 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
3690 A test port of gdb-3.92.6 to the Sony NEWS.
3693 Don't normally link in remote- or vx stuff.
3694 Some of it doesn't compile, and it wastes space for 99% of the users.
3695 Remove reference to no-longer-used HAVE_VPRINTF.
3696 Fixed BFD_DEP typo to BFD_DIR.
3698 Fix cast in arg to bfd_h_getlong.
3699 Make char *prefix be const.
3700 Fix how certain range types are mapped into builtin unsigned int types.
3702 Remove 2 #includes. They cause errors (on Sony, at least),
3703 and aren't needed (they wern't in earlier versions).
3705 print_address_symbolic should never demangle labels
3706 (since it prints *assembler-level* labels).
3708 [This was superseded by the change to printcmd below.]
3711 Add some "volatile" return types to avoid warnings.
3712 If MISSING_VPRINTF add vprintf function and not just macro
3713 (since vprintf is used in printcmd.c).
3715 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
3716 (The latter isn't grokked by some PCC-based compilers.)
3718 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
3720 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
3721 * nindy-share/coffstrip.c
3722 Added some forward declarations (otherwise, gcc complains
3723 about implicit extern redefined as static).
3725 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
3727 Changes inspired by Per Bothner:
3728 * printcmd.c (print_address_symbolic): Take additional parameter
3729 specifying whether to demangle.
3730 (print_address): Pass in asm_demangle to control demangling.
3731 (print_address_demangle): New fn, takes explicit arg to control
3733 * utils.c: Add new vars demangle and asm_demangle, and let them
3735 (fputs_demangled): If !demangle, just print the argument.
3736 (fprint_symbol): If !demangle, just print raw symbol.
3737 * valprint.c (val_print): Call print_address_demangle rather than
3738 print_address, to cause demangling to depend on the global
3739 rather than assembler-level demangling setting.
3740 * WHATS.NEW, gdb.texinfo: Document.
3742 * main.c (show_command): Show all settings if no arg.
3743 (initialize_main): Make "info set" the same as naked "show".
3744 * command.c (cmd_show_list): Handle prefix commands in the
3745 list, and print the name of the setting as well as its English
3746 description and value.
3748 Allow gdb functions to specify where a line should wrap if it
3749 exceeds the size of a terminal line. Use it to make the output
3751 * utils.c (set_screen_width_command): New fn, mallocs a buffer
3752 of the right size when screen width changes.
3753 (set_screensize_command, screensize_info): Remove #if 0'd fns.
3754 (wrap_here): New fn, indicates a point in the output where we
3755 should wrap the line rather than just letting it overflow at a
3757 (fputs_filtered): Implement wrapping.
3758 (n_spaces): New fn, returns a pointer to N spaces.
3759 (print_spaces_filtered): Use n_spaces.
3760 * defs.h (n_spaces): Declare.
3761 * stack.c (print_frame_info): Wrap with 4-space indent after
3762 fn name and before filename and line number.
3763 * printcmd.c (print_frame_args): Wrap with 4-space indent
3764 before each argument name is printed.
3765 * valprint.c (value_print): Wrap with no indentation before
3767 (val_print_fields): Wrap with indentation relative to nesting
3768 level before each field name.
3769 (val_print): Wrap with nesting indentation before array elements.
3770 * command.c (do_setshow_command): Avoid extra newlines,
3771 wrap with 4-space indent around values printed, end with period.
3772 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
3774 * breakpoint.c (breakpoint_1): Implement addressprint for
3775 "info breakpoints" display. Change file name and line number
3776 format to " at file:nnn" rather than " (file line nnn)".
3777 * gdb.texinfo: Document.
3780 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3782 Frozen for gdb-3.92.6 release.
3784 README, WHATS.NEW: Update for 3.92.6 release.
3786 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
3787 coffread.o from configs since it is now built by default.
3788 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
3789 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
3790 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
3791 from configs since it is now built by default.
3793 Makefile.dist: Update for release 3.92.6. Handle files that
3794 have been moved to ../include, ../getopt, or ../bfd. Add
3795 saber.suppress and tests directory. Add config.status to
3796 the release (it will say "none").
3798 coredep.c: Minor formatting fixes.
3800 These changes were made in early December but only checked in now:
3801 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
3802 nindy-share/nindy.c: lint
3803 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
3804 register values coming back from the target; we store values
3805 in target byte order everywhere.
3807 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
3809 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
3811 * valprint.c (cplus_val_print, val_print_fields): New functions,
3812 which print C++ objects. They conspire to avoid printing a
3813 virtual base class more than once, following all the twists and
3814 turns of C++ virtual base rules.
3815 (val_print): Call the above rather than do it by hand.
3817 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
3818 symbol file, not for added files like shared libs. This really
3819 needs to be generalized to a timestamp per file.
3821 * core.c (cleanup_core): Avoid coredump if no core file.
3823 * config.gdb: Accept -host or -target in place of +host or
3826 * coffread.c (find_linenos): Avoid desupported BFD interface
3827 to line numbers. We still read them manually rather than using
3828 BFD's "generic" features.
3830 * gdbrc.tex, threecol.tex: Add GDB reference card and its
3832 Makefile.dist: Add refcard to OTHERS list for creating tar files.
3834 * Makefile.dist: Eliminate use of $< in explicit targets.
3836 * readline/Makefile: Use $< rather than $*.c, which does not
3837 include the VPATH in GNU Make.
3839 * tconfig/i960-bout, tconfig/i960-coff: These are identical
3840 copies of tconfig/i960, added for global configuration
3841 compatability. All i960 versions can read both coff and b.out.
3843 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
3844 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
3847 * TODO: Think of more things to do.
3849 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
3851 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
3852 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
3853 64-bit float conversion.
3855 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
3856 equivalent to sun?os4 so global config works.
3858 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
3860 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
3862 * main.c: Only declare linesize once; declare pagesize not at
3863 all, since it is never used.
3864 (main): Clear newly allocated line before it is used.
3866 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
3868 Further stabilization for the Intel 960.
3870 * Makefile.dist: Parameterize the location of the "include"
3871 and "bfd" directories, as well as "getopt". Add symfile.c.
3872 Link in both dbxread and coffread. Fix up "make depend" to
3873 rewack the locations of include, bfd, and getopt in its output.
3875 * README: Document moving include files, improve some of
3878 * coffread.c: Move common code out to symfile.c. Change
3879 symbol_file_command style interface to use new *_symfile_init
3880 and *_symfile_read interface under BFD. Use BFD internal
3881 info to locate line table, symbols, etc.
3883 * core.c (core_fetch_registers): Rename to get_core_registers
3884 to avoid confusion with fetch_core_registers.
3885 (register_addr): Move to coredep.c, which is already machine
3886 dependent. This leaves core.c pretty clean of dependencies.
3888 * coredep.c (register_addr): Accept this routine from core.c.
3890 * dbxread.c: Move common code (with coffread.c, etc) into new
3891 symfile.c. Each psymtab now contains a pointer to the
3892 format-dependent function that knows how to read it in. Make
3894 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
3895 (process_one_symbol): Add code to complain about a "compiler bug
3896 we muzzle here", if we actually see it.
3898 * eval.c (evaluate_subexp): Insert missing "break" statements
3899 in code that determines whether a variable is an lvalue in
3900 memory, register, or whatever. I detected this via a compiler
3901 bug in which it *almost* mashed out the whole switch statement.
3903 * gdb-int.texinfo: Add minor sections on configuring gdb for
3904 release, and about the README file.
3906 * infcmd.c (registers_info): Fix formatting somewhat. Still
3907 not as pretty as before, but it handles byte swapping.
3909 * remote-nindy.c: If data cache routines are interrupted while
3910 waiting for the remote end, be sure that any uninitialized cache
3911 blocks are on the free list, not on the valid list!
3913 * symfile.h: Flesh out this header file with all the various
3914 routines and variables that have been merged in from dbxread.c
3915 coffread.c, and symtab.c to symfile.c.
3917 * symfile.c: New file, containing code common to dbxread.c,
3918 coffread.c, and some code from symtab.c. All generic code for
3919 reading symbol files should be in here now.
3920 (unrecord_misc_function): Remove unused function.
3922 * symtab.h: Remove file-reading things to symfile.h.
3924 * symtab.c: Remove file-reading things to symfile.c.
3926 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
3927 to decode i960 fault types.
3929 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
3930 target.c: Change type of the "resume" function from int to void,
3931 since its result was never used.
3933 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
3935 * main.c: Replace "stupid" with "caution"; you now "set caution
3938 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
3940 * infcmd.c (do_registers_info): Call val_print to deal with the
3941 byte order of the registers being printed. FIXME, this makes
3942 the formatting of the output uglier.
3944 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
3945 defined, call it for signals the debugger doesn't itself use.
3946 The i960 uses this for more detailed fault information.
3948 * remote.c (remote_open): If arg is null, print help rather than
3951 * sparc-xdep.c (register_valid): Avoid declaring size, since
3952 various modules will think of various sizes depending on the
3953 architecture of their tm-file. FIXME, we need protection against
3954 actually entering one of those modules, which would clobber
3955 storage if not for the target architecture compiled into gdb.
3957 * stack.c (up_command, down_command): Always print the frame
3959 (up_silently_command, down_silently_command): New commands
3962 * i960-pinsn.c (reg), i960-tdep.c: Lint.
3964 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
3965 more parameters than it used to.
3967 * findvar.c (registers): Increase slop to 256 bytes, which should
3968 protect us against even most RISC machines with large register
3970 (locate_var_value): Move declaration inside related ifdef.
3972 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
3973 throughout, to avoid throwing away buffered input from the board.
3974 (nindy_wait): Supply_register takes addr_of_value, not value.
3975 (i960_print_fault): Renamed from i80960_fault.
3976 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
3977 (nindy_store_registers): Avoid regs_changed stuff, just stuff
3979 (nindy_create_inferior): Don't bother to write PC_REGNUM since
3980 we can set the PC in the call to proceed(). Unpush nindy_ops
3981 before pushing it on top, to avoid message to user. Eliminate
3982 commentary from Unix machines that just misleads here.
3983 (reset_command): Fix error message to suggest target command.
3985 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
3987 Release 3.92.5 as frozen.
3989 Stabilize the merged release...with help from lint, Saber C,
3992 Everywhere: Add include files needed to declare return types
3993 of functions called.
3995 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
3997 * breakpoint.h: Add undeclared breakpoint functions, and some
3998 functions for display handling since I couldn't think of a better
4001 * breakpoint.c (insert_breakpoints): Make code for disabling
4002 shared library bkpts more likely to work. It's used when we
4003 rerun a program and stop before the shared library has been
4005 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
4006 cast from pointer, so it squeezes through catch_errors.
4007 (bpstat_stop_status): Fix logic broken some time ago. We now
4008 always create a bpstat if the stop address matches a breakpoint,
4009 even if we don't stop there -- just like the old code used to do
4010 before I got my fingers into it (sigh).
4011 (breakpoint_1): Print "ignore count" after "stop only if"
4012 condition, since that's how it actually works.
4013 (mention): Handle watchpoints as well as breakpoints.
4014 (watch_command): use set_raw_breakpoint and mention to do most
4015 of the work (and initialize all the fields!). Only pass one
4016 arg to parse_c_expression, since that's all it takes.
4018 * command.c (not_just_help_class_command): Rename arg to args
4019 since we ignore "unused argument" warnings on vars named "args".
4020 inflow.c (child_terminal_info): ditto.
4021 infptrace.c (kill_inferior): ditto
4022 main.c (catch_errors, version_info, quit_command, pwd_command,
4023 source_command, dump_me_command, editing_info,
4024 set_history_size_command, set_history, show_history,
4026 stack.c (locals_info): ditto
4027 target.c (target_files_info): ditto
4028 valprint.c (set_input_radix, set_output_radix): ditto
4030 * core.c: Remove old variables for handling core and exec file
4031 sections (data_start, data_end, stack_start, stack_end,
4032 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
4033 text_end, exec_data_start, exec_data_end, text_offset,
4034 exec_data_offset, data_offset, stack_offset). They're
4035 superseded the more general build_section_table and
4037 (get_exec_file): Mention the `file' command.
4038 (read_memory_check): Rename to memory_error, and only call it
4039 in the case of an actual error.
4040 (read_memory, write_memory): call memory_error.
4041 (core_fetch_registers): Register section name is ".reg".
4043 coredep.c: Remove a bunch of crud now that all this file does
4044 is pull the registers out of a core file.
4045 (fetch_core_registers): Rewrite to actually work, I hope.
4047 dbxread.c: Use a.out.gnu.h, not system a.out, now.
4048 Replace index() with strchr(). Remove all the pre-BFD macro
4049 definitions for accessing the symbol file.
4050 (struct dbx_symfile_info): Encapsulate the information that
4051 dbx_symfile_init needs to pass to dbx_symfile_read in this
4054 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
4055 dbx_symfile_discard): Rearrange symbol file reading to divide
4056 the format-specific part from the format-independent part,
4057 leaving the format-independent part such as file name expansion
4058 and opening in symtab.c. This replaces
4059 partial_symbol_file_open and partial_symbol_file_read.
4060 Symbol_file_read, add_file, add_file_target_command,
4061 add_file_addr_command move to symtab.c. Pass an explicit
4062 "mainline" flag for when reading the main symbol table, rather
4063 than relying on the offset address to be zero or nonzero.
4065 (dbx_symfile_read): Don't allow void *'s to be printed as
4067 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
4068 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
4069 macro" debug version really work.
4070 (read_dbx_symtab): Remove unref'd parameter inclink.
4071 Avoid swapping N_SLINE symbols, for speed.
4072 Merge N_TEXT!N_EXT case with the other external symbol
4073 definitions' case. Add comments.
4074 (start_psymtab): Allocate the symfile name in the psymtab on
4075 the psymbol_obstack, rather than using the caller's storage.
4076 (end_psymtab): Only allocate a dependencies list if there are
4078 (psymtab_to_symtab_2): Use BFD when reopening file to read
4079 its symbols for real.
4080 (read_struct_type): Add FIXME comments where it needs work
4082 (read_huge_number): Add FIXME about overflows.
4083 (read_range_type): Add FIXME about comparing a long to 1<<32.
4085 * coffread.c: Minor changes to move things closer to the new
4086 regime with symtab.c and dbxread.c Major work is still needed
4089 * exec.c (exec_file_command): Remove old variables (see core.c
4091 (xfer_memory): If memory transfer is right at the end of a
4092 section, don't lose.
4094 * findvar.c (get_saved_register): If value is in a real
4095 register, LVAL is lval_register, not lval_memory.
4097 frame.h: Declare print_sel_frame and record_selected_frame.
4099 gdb-int.texinfo: New file, for GDB internals documentation.
4100 Very simple, unformatted doc of cleanups is there for now.
4102 gdbcore.h: Remove obsolete variables that described a.out
4103 section addresses and offsets. (See core.c above.)
4104 Declare fetch_core_registers and registers_fetched.
4106 getopt.c: Declare char *alloca(); even on SPARC.
4108 infcmd.c (run_command): Call target_kill rather than
4110 (step_command, next_command, stepi_command, nexti_command):
4111 Declare from_tty parameter even though we don't use it.
4112 (run_stack_dummy): argument BUFFER is a char array, not
4113 a pointer to REGISTER_TYPE.
4114 (finish_command): using_struct_return needed a value *,
4115 not a struct symbol *.
4117 * infptrace.c (child_xfer_memory): To avoid dependency on
4118 where sections are in memory, try PT_WRITE_D and if that fails,
4119 try PT_WRITE_I. Most Unixes don't care which you use.
4121 * infrun.c (step_resume_break_shadow): Change to array to
4122 match other breakpoint shadow storage.
4123 (clear_proceed_status): Pass address of bpstat to
4124 bpstat_clear, not the bpstat itself.
4125 (child_create_inferior): FIXME comment about if the child
4127 (start_inferior): Remove old function.
4128 (child_open): Use target_kill rather than kill_inferior.
4129 (wait_for_inferior): Ditto.
4130 (insert_step_breakpoint, remote_step_breakpoint): Use
4131 new step_resume_break_shadow.
4133 * inftarg.c (child_wait): If all child processes die,
4134 pretend that the one being waited for exited with signal 42.
4136 * main.c (command_line_input): When scanning for comments,
4137 don't coredump on unclosed quotes.
4138 (quit_command): Use target_kill rther than kill_inferior.
4139 (_initialize_main): Rename class_user from "user" to
4142 * printcmd.c (print_command_1): Initialize "fmt" if no format
4143 is specified by the user.
4144 (print_frame_args): Only add to args_printed if we are
4145 actually fetching args from the stack (avoiding undefined
4147 (_initialize_printcmd): Remove bogus \{ from string.
4149 * remote-eb.c (eb_open): Avoid coredump on no argument.
4151 * remote-nindy.c: Bring out of Intel environment into new
4152 target environment. Remove all conditional compilation on
4153 I80960. Massive hacking throughout.
4154 (nindy_xfer_inferior_memory): New routine stolen from
4156 (nindy_create_inferior): New routine pieced together, probably
4157 not quite working yet.
4158 (nindy_ops): New target_ops struct for nindy.
4160 * remote-vx.c: Use write_memory rather than target_write_memory
4161 to get error checking.
4162 (vx_add_file_command, vx_open): Use symbol_file_add rather than
4164 (vx_create_inferior): Use target_terminal_ours...
4166 * signame.c (_initialize_signame): Always initialize, since
4167 we need the table for things other than psignal.
4169 * solib.c (solib_add): Use symbol_file_add, not add_file.
4170 (solib_address): Return boolean result rather than struct
4171 pointer which nobody else knows the type of.
4173 * sparc-tdep.c, valops.c: Use write_memory rather than
4174 target_write_memory, to get error checking.
4176 * stack.c (locals_info, catch_info, args_info,
4177 get_selected_block, frame_command, up_command): Use
4178 target_has_stack, rather than have_inferior_p or
4181 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
4183 * symfile.h: New file, defining the interface between the
4184 generic and object-file-specific symbol reading code.
4186 * symtab.c: Move generic symbol-reading interface to symtab.c,
4187 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
4188 table to map BFD targets to symbol-reading modules in GDB.
4189 Change index to strchr.
4190 (lookup_struct_elt_type): Use error() rather than hand-made
4191 simulations thereof.
4192 (lookup_partial_symbol): Speedup slightly when length == 0.
4193 (symbol_file_add): New function.
4194 (symbol_file_command): Call it.
4195 (symfile_open, symfile_init): New function.
4196 (add_file_target_command, add_file_addr_command): moved from
4199 * target.c (target_command): use target_kill.
4201 * target.h (target_files_info): Don't declare, never called
4204 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
4205 files to determine stack end address.
4207 * valarith.c (value_x_binop, value_x_unop): Change error message
4208 to be more useful. Pass proper argument to value_struct_elt.
4210 * valops.c (value_assign): FIXME comment that long long
4211 bitfields will break here.
4213 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
4214 Update `make saber_gdb' to work better.
4216 * TODO: A woman's work is never done.
4218 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
4219 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
4220 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
4221 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
4222 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
4223 valops.c, valprint.c, exec.c: Lint.
4226 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
4228 Continuing Intel 960 port merge of GDB.
4230 * Makefile.dist: Merge i960 "nindy-share" files. Rename
4231 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
4232 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
4233 Wack over "make depend" so it handles files in subdirectories
4234 vx-share, nindy-share, bfd, and in the current directory.
4236 * blockframe.c (get_prev_frame_info): Remove fatal error
4237 if stack not defined.
4239 * core.c (core_open, core_detach): New functions that handle
4240 the old "core-file" command as "target core" and "detach" instead.
4241 (core_file_command): Call them.
4242 (core_xfer_memory): Use common routine xfer_memory.
4244 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
4245 dbxread now uses bfd for everything but symbol reading itself.
4246 BFD internals are used to drag out the relevant file offsets.
4247 (partial_symbol_file_open): Change args all around for BFD.
4249 * symtab.c: Rename "value" to "val" everywhere, so we can
4251 (symbol_file_command): New command, moved from dbxread.c
4252 and coffread.c. It uses BFD to read the file, then vectors
4253 based on its type, to dbx or coff symbol readers.
4254 * symtab.h: Extern a few vars for symbol_file_command.
4256 * target.h: Breakpoint takes a char * save area, not a char **.
4258 * valprint.c (val_print): When unpacking bitfields, offset
4259 the address in gdb of the value, if it is declared with a shorter
4260 type. Remove the last "runtime kludge test" of host byte order.
4262 * utils.c: Remove old my_bfd_read routine.
4264 * stack.c (frame_info): Use target_has_stack. Print program counter
4265 register's actual name rather than "pc", since it's called the
4266 "ip" (instruction pointer) on the i960 (sigh).
4268 * target.c (target_command): Add command for selecting a target
4269 type and calling its open routine. This is used for initiating
4270 communication with a particular target, in a generic way.
4272 * tm-i960.h: Update for modern gdb. Remove semicolons from
4273 various macros. Handle reading struct return convention, and
4274 error-out attempts to return structs with the "return" command.
4275 Be sure gdb doesn't think we know how to call functions in the
4278 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
4279 to i960_xxx in lower case.
4280 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
4281 not being defined yet.
4283 * remote.c (remote_open): Call start_remote to initialize
4284 wait_for_inferior during open.
4285 (remote_xfer_inferior_memory): Return length written rather
4288 * remote-vx.c (target_command -> vx_open): Use new generic
4290 * remote-eb.c, inftarg.c, exec.c: ditto.
4292 * infrun.c: Fix comments.
4293 (attach_program -> child_open): Use new generic target command.
4294 (wait_for_inferior): Clear saved register values before target_wait,
4295 so target_wait can set some of them if convenient.
4297 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
4298 Return success indicator, not void.
4299 (child_xfer_memory): Avoid fetching initial word if we'll
4300 overwrite it anyway.
4302 * infcmd.c (attach_command): Use new generic target open routine.
4303 (_initialize_infcmd): Update doc on attach and detach commands.
4304 (do_registers_info): Merge in a byte-order problem as a FIXME
4307 * findvar.c (find_saved_register): Avoid problem in current frame.
4308 (read_relative_register): Ditto.
4309 (write_register): Convert byte order on the way out.
4311 * exec.c (file_command): Add.
4312 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
4313 (xfer_memory): Common function between core_xfer_memory and
4315 (exec_xfer_memory): Use it.
4317 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
4319 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
4320 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
4321 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
4323 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
4325 Merge Intel 960 port of gdb, continuing...
4327 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
4328 symbol_file_command): Pass from_tty arg to hush 'em up.
4330 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
4331 Add magic numbers for 960 COFF format.
4333 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
4335 Merge Intel 960 port of gdb, from Intel "1.2" release.
4337 CHANGE_LOG entries from their port, which was based on
4340 Thu Sep 6 11:02:22 PDT 1990
4341 Remove temp file if download is interrupted.
4343 Wed Aug 1 09:08:33 PDT 1990
4344 Now uses binary protocol to talk to NINDY.
4345 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
4346 Times out after 5 seconds when trying to talk to NINDY.
4348 Tue May 29 12:54:49 PDT 1990
4349 Added variable baud rate (-b switch).
4350 Source code reorganization.
4352 Thu Apr 26 11:09:55 PDT 1990
4353 More cleanup of batch mode; specifically, execute "-s", "-e", and
4354 "-se" switches as soon as they are encountered on the invocation line.
4356 Fri Apr 20 13:47:15 PDT 1990
4359 Thu Apr 19 09:54:28 PDT 1990
4360 Add 'reset' command.
4362 Wed Apr 18 09:48:07 PDT 1990
4363 After opening remote tty, wait for 1 second to go by without input
4364 from it before trying to talk to NINDY (fixes problems with the
4365 Heurikon HK80/V960E).
4367 Mon Apr 4 16:33:05 PDT 1990
4368 Some output was not being suppressed in 'batch' mode.
4370 Thu Mar 22 15:31:11 PST 1990
4371 Ask user if old symbol table should be deleted when new file is
4374 Allow user to run a program downloaded before gdb960 was brought up.
4376 Correct "exec-file" help message for i80960 context.
4378 Correct bug in calculating user space address: could occasionally
4379 corrupt user program.
4381 Make sure to zero low-order bits in rip's because of bug in 960CA
4382 A-step part: could cause operation faults when "next"ing across
4385 Correct bug that made it impossible to get source line numbers for
4386 code loaded at addresses higher than 0x7fffffff.
4388 Wed Jan 10 12:43:22 PST 1990
4389 Open remote tty for exclusive use.
4391 Fri Jan 5 12:14:42 PST 1990
4392 Correct disassembly (CA manual was right after all):
4393 opcode for sysctl is 0x659
4395 Mon Oct 23 12:03:04 PDT 1989
4396 Use G960BASE and G960BIN environment variables to find 'sx' utility.
4398 Mon Oct 16 14:15:09 PDT 1989
4399 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
4401 Mon Oct 2 15:56:31 PDT 1989
4403 Added 960CA disassembly support.
4405 To simplify maintenance:
4406 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
4408 - eliminated opcode.h: incorporates tables into i960-pinsn.c
4409 - moved 960-specific routines from i960-pinsn.c to i960-md.c
4410 - made disassembly interface identical to that in gdmp960.
4414 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
4416 * target.h: Allow targets to stack. Add target_has_memory,
4417 _registers, etc. Restructure memory access and "info files"
4418 to walk the target stack.
4419 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
4420 target.c: Change tables to match target.h.
4421 * inflow.c (child_mourn_inferior): pop child_ops.
4422 (generic_mourn_inferior): Use new has_stack flag.
4423 * infptrace.c (child_xfer_memory): New memory regime.
4424 * inftarg.c (child_files_info): New "info files" regime.
4425 * remote-eb.c: New memory regime, new info files.
4426 * remote-vx.c: New memory regime, new info files. Now use
4427 separate targets for VxWorks attachment to machine, and
4428 actually running a process under VxWorks, since one has
4429 stack & execution & regs and the other doesn't.
4430 * remote.c: New memory regime, new info files.
4431 * sparc-xdep.c (fetch_core-registers): New memory regime.
4432 * target.c: New routines and support for stacked targets,
4433 new memory regime, new info files regime.
4436 Generalize section handling for an arbitrary number of sections,
4437 including use of the new BFD (binary file) library.
4438 * gdbcore.h: Add struct section_table.
4439 * exec.c (build_section_table): Iterate all sections and
4440 record what gdb needs to know about them.
4441 (exec_command): Use it.
4442 (exec_xfer_memory): Use the table.
4443 (exec_files_info): Print the table.
4444 * core.c (core_file_command, core_xfer_memory, core_files_info):
4446 * source.c (find_source_lines): Use bfd_get_mtime.
4447 * dbxread.c: Quick changes to make it compile with new BFD.
4448 * utils.c (error): Avoid using bfd_error in generic routines.
4450 * core.c (core_fetch_registers): Get from the ".regs" section of
4452 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
4454 * inferior.h (attach_flag): Export.
4455 * infcmd.c (run_command): use new target_create_inferior.
4456 * infrun.c (child_create_inferior): Don't return result.
4457 * Makefile.dist (VERSION): 3.91.4.
4459 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
4461 * breakpoint.c (bpstat_num): Handle breakpoints which have
4462 since been deleted, such as temporary breakpoints.
4463 infcmd.c (program_info): ditto.
4465 * core.c (core_file_command): Display the frame where the core
4470 * remote-vx.c (target_command): Merge in target command from
4471 targ-vx.c. A few other cleanups.
4473 * TODO, Projects: Lots more stuff to do...
4475 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
4477 Massive changes to wall off the remote-debugging interface
4478 behind a function vector. The port to handle VxWorks targets
4479 is also part of this.
4481 All files: Replace references to renamed functions,
4482 remove references to remote_debugging, remove references to
4483 have_include_file, have_core_file in favor of target_has_stack,
4484 target_has_memory, etc.
4486 * Modularize the breakpoint interface.
4487 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
4488 a breakpoint instruction.
4489 breakpoint.c: struct breakpoint's shadow_contents now sized as
4491 (insert_breakpoints): Vector to target to install breakpoints.
4492 (remove_breakpoints): Vector to target here too.
4493 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
4494 sparc-tdep.c (single_step): Use new breakpoint interface for
4495 the single-step breakpoints.
4496 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
4497 New file, contains routines to insert and remove breakpoints by
4498 reading out the old contents and later replacing them. This is
4499 how ptrace breakpoints work, and many remote systems as well.
4501 * tm-vxworks68.h: New config file, overrides a few things for
4502 Wind River's preferences.
4504 * target.h: New file, for transfer vector used to talk to the
4505 inferior (child, attached, core, exec, remote, etc). All accesses
4506 to the thing being debugged should come through these vectors.
4507 target.c: New file, routines to handle transfer vector.
4508 (various files): Add transfer vectors XXX_ops for the various
4509 targets and pseudo-targets (core files, etc) we support.
4511 * breakpoint.c (bpstat_stop_status): Further explorations of
4512 watchpoints and why things don't work all the time.
4513 (bpstat_alloc): New fn to allocate a bpstat and chain it.
4515 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
4516 the local gdbinit if it doesn't already have it.
4518 * core.c (core_ops): add and install.
4519 Allow core debugging without exec file.
4521 * dbxread.c (free_and_init_header_files): Merge two fns.
4522 (end_symtab): Free named symbol table when a new version comes in.
4523 (read_dbx_symtab): Relocate all kinds of symbols with base
4524 address. First step toward handling different text, data, bss
4526 (add_file_addr_command): Renamed add_file_command.
4527 (add_file_command): Vector to remote handler.
4528 Add "load" as an alias for "add-file" command.
4530 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
4531 non-returning functions.
4533 * exec.c: Add exec_ops, and push it as a target when an exec
4536 * infcmd.c (run_command): Pass executable file name and arg list
4537 separately when starting an inferior. Permit "run" when no exec
4538 file is specified, for VxWorks.
4539 (detach_command): Move to child_detach in inftarg.c.
4541 * inftarg.c: New file. Unix-child-specific routines, and the
4542 child_ops structure.
4544 * inferior.h (registers): Export "registers" as the way for
4545 target dependent register handlers to find gdb's local copy of
4546 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
4547 since it is now used by places that want wait_for_inferior to
4548 handle the grunge but want to see every trap from the inferior.
4550 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
4551 Eliminate remote_debugging hooks in terminal handling.
4553 * infrun.c: Replace start_inferior with child_create_inferior.
4554 Move all the hair of Unix shells and ptrace idiosyncracies into
4555 child_create_inferior, so remote handlers don't have to deal.
4556 Remove running_in_shell. Rename stop_after_attach to
4557 stop_soon_quietly, and use it in a few other places where we want
4558 to just call wait_for_inferior and get control back on the first
4559 trap. trap_expected now never takes a value > 1.
4560 (init_wait_for_inferior): Initialize static vars when a new
4563 main.c (gdbinit): Add new hook for .gdbinit file name, let
4564 it be overridden by config files as GDBINIT_FILENAME.
4565 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
4566 Both of these are used for VxWorks gdb.
4568 mcheck.c: rename include file "gmalloc.c" to avoid problems
4569 with system include file "malloc.c".
4571 param-no-tm.h: New include file, same as param.h but does not
4572 include the default "tm.h" file. This is used in files where
4573 the target is known, e.g. remote-eb.c or sparc-xdep.c.
4575 param.h: Now just a shell that includes tm.h and param-no-tm.h.
4577 remote-vx.c: New file, VxWorks remote debugging support. Uses
4578 RPC routines that are shared with the target system, in directory
4581 remote.c: Vectorize remote interface.
4583 source.c: Globalize source_path, and make an alias "l" for "list"
4584 since we now have the "load" command.
4586 sparc-xdep.c: Use new param-no-tm.h.
4588 symmisc.c (free_named_symtab): Add new function from Wind River.
4589 However, ifdef it out for now while we think about what it should
4592 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
4594 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
4595 non-Unix-children handle this with their own code in the target
4598 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
4599 source and target lists. Add vx-share to default list of include
4600 directories. Add new files to src and target lists: mem-break,
4601 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
4602 ${srcdir} versions of munch and createtags are used.
4604 * valops.c (find_function_addr): Split out of call_function.
4605 (call_function_by_hand): Rename call_function; this function
4606 calls functions in the target by laboriously patching the target
4607 word-by-word with the right stack, args, regs, etc.
4610 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
4612 Handle AMD 29000 a bit better.
4614 * remote-eb.c (readchar): Mask received char log to make it readable.
4615 (remote_start): Pass arguments down to executing program.
4616 Make startaddr unsigned.
4617 infrun.c (start_inferior): Accept args, pass them to
4619 infcmd.c (run_command): Pass args down to start_inferior.
4621 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
4622 the target object file format.
4623 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
4625 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
4626 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
4628 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
4630 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
4631 * TODO: We did a few things, we have more to do though.
4633 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
4634 * inflow.c (inferior_died): Clear deferred stores.
4636 * Debug problems with dummy frames and calls to the inferior.
4637 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
4638 * sparc-tdep.c (do_restore_insn): Simplify.
4639 (sparc_frame_find_saved_regs): Simplify and fix what we find.
4640 (sparc_push_dummy_frame): Simplify and fix what we push.
4641 (sparc_pop_frame): Slightly more hair here, deciding whether
4642 we are restoring a saved PC or returning to a return address in %i7.
4643 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
4645 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
4646 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
4647 * obstack.h (chunkfun): ditto.
4648 * defs.h (xmalloc, xrealloc): ditto
4650 * utils.c (quit): Grab the terminal from the child if necessary.
4652 * inflow.c (term_status_command): Rename to term_info, change
4655 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
4656 (is_delayed_branch): Speed up.
4657 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
4658 Still missing some float ops, and needs testing.
4660 * Support for input and output radixes other than base 10
4661 * defs.h (input_radix, output_radix): Declare.
4662 * expread.y (yyparse, parse_number): Handle changes of input
4663 radix, and ambiguous names-or-numbers in radixes >10.
4664 * printcmd.c (print_scalar_formatted): Print formatted hex
4665 numbers in varying column widths.
4666 * valprint.c (val_print): Use output_format to print scalar ints.
4667 (set_input_radix, set_output_radix, set_radix): Create.
4668 (set_output_radix): Set output_format from output_radix.
4669 (_initialize_valprint): add `set radix' but leave the others off.
4671 * main.c (execute_command): Let stupid questions be turned off.
4672 (_initialize_main): Handle "set stupidity", etc.
4674 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
4675 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
4677 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
4679 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
4680 bfd stuff is still screwed up, but with some manual work, it
4683 * breakpoint.c (bpstat_do_actions): Start over if a command
4684 proceeds the inferior, since the inferior will have stopped and
4685 will need to have its new stop-actions taken care of.
4687 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
4688 compiler fits, simplify it.
4690 * gdb.texinfo (directory command): Doc new dir command.
4691 source.c (directory_command): "dir" now puts things on the front
4692 of the path, moves dups up front, and handles multiple names
4693 on the command line, inserting each one in order. It also
4694 blows away cached line and full_filename info.
4696 * stack.c (backtrace_command): Skip "more stack frames follow"
4699 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
4700 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
4701 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
4702 The only odd one was Gould NP1, which had defined vprintf to
4705 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
4706 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
4707 variable, inspect_it.
4708 valprint.c (print_string, val_print): Use the global inspect_it
4709 to indicate whether to print in Epoch style or normal style.
4711 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
4713 * printcmd.c (call_command): add an alias for the "print" command
4714 which runs expressions and doesn't print the result if void.
4715 (print_command_1): implement it.
4717 * command.c: Remove #if 0'd code. Initialize all the fields
4718 in add_cmd (). Rename do_nothing_command to
4719 not_just_help_class_command, and make it externally visible.
4720 command.h: add user_commands to struct.
4721 * main.c (define_command): Don't overload c->function with a char
4722 string as well as a function pointer.
4724 * eval.c (evaluate_subexp): Reinstall tiemann changes to
4725 calling convention of value_struct_elt () that got dropped in
4728 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
4729 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
4731 * tm-sparc.h (POP_FRAME): replace some constants with defines.
4733 * sparc-xdep.c (store_inferior_registers): defer stores to regs
4734 until a good time (e.g. when we are about to run the child),
4735 saving ptrace calls.
4736 * infrun.c (proceed): handle DO_DEFERRED_STORES.
4737 * tm-sparc.h: define DO_DEFERRED_STORES.
4739 * sparc-xdep.c (store_inferior_registers): when storing float
4740 registers, don't store stack regs too. When storing the SP,
4741 however, DO store the stack regs too. This fixes a bug in which
4742 the dummy frame is not recognized when a call_function finishes,
4743 because its frame pointer (in the stack regs) was never
4745 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
4746 even though we don't know how to read them from an inferior.
4747 valops.c (call_function): Comment about storing SP.
4749 * infrun.c (save_inferior_status): Save away the original bpstat
4750 chain so it can be restored later. Install the copied version for
4751 use by whoever saved the status. It will be blow away by
4752 restore_inferior_status, and the original chain restored. This is
4753 important for people who have pointers into the original.
4755 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
4756 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
4757 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
4760 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
4762 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
4763 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
4764 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
4766 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
4768 * Merge Mike Tiemann's multiple inheritance changes from Sun.
4769 Store the baseclasses in a type struct starting from array element
4770 0 rather than from the unusual array element 1.
4772 dbxread.c: the above.
4773 (virtual_context): Add
4774 Read new debug information about which virtual function table
4775 a virtual function is from, and store it in fn_field.fcontext.
4777 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
4778 TYPE_FN_FIELD_STATIC_P.
4780 symtab.c: the above.
4781 valops.c: the above. Handle pointer casts of object *'s.
4782 (search_struct_method): Add.
4783 (value_struct_elt): First arg is now a pointer to a value, and is
4786 valprint.c: the above.
4787 values.c (value_virtual_fn_field): Add type arg. Handle
4788 offsetting to the proper object when calling virtual fns.
4790 (baseclass_addr): Add valuep arg.
4792 * README: Document the current state of BFD config (missing).
4793 * TODO, ChangeLog, Makefile.dist: Roll version.
4794 * WHATS.NEW: Add summary of changes since 3.5.
4796 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
4798 * dbxread.c (read_struct_type): Clear bit vectors whenever
4800 symtab.c (B_CLRALL): define.
4802 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
4803 using == rather than =. Huh... This fixes the dreaded problem
4804 wherein builtin_type_int becomes TYPE_CODE_FLT.
4806 * core.c (info_files): Show the inferior pid.
4808 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
4809 already knows how to look in the source directory.
4811 * Remove psymtab hair from many places. Remove duplicated code
4812 for searching symbol tables. Hide psymtabs from most places.
4813 Make it fast to get from a psymtab to its symtab.
4815 blockframe.c (blockvector_for_pc): Remove psymtab hair.
4816 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4817 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4818 dbxread.c: export psymtab_to_symtab, make it work if called N times.
4819 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
4820 new symtab completely. New psymtabs get symtab pointer
4821 initialized to zero. Remove MI warning printf.
4822 symtab.h: Comments. Add psymtab to symtab pointer.
4823 (PSYMTAB_TO_SYMTAB): New macro.
4824 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
4825 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
4827 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
4829 (print_frame_info): Avoid special-casing symbols that have not yet
4832 * source.c (open_source_file): Quick path if we have already
4833 located the source file by its full name.
4835 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
4836 find_pc_psymtab. When a name is found in the misc function
4837 vector, search the symbol table for its mangled name, not the
4838 name that the user typed.
4840 * bfd.h: Fix missing comment terminators, make #endifs match.
4842 * valarith.c (value_less): Handle unsigned int comparisons.
4843 Add FIXME about pointer compares, which assume host and target
4844 pointers are the same.
4846 * command.c (do_nothing_command): lint
4847 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
4848 fix comments on debug symbol format for visibility. Actually set
4849 visibility of symbols.
4850 main.c (echo_command): lint; use <readline/history.h>.
4851 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
4852 obstack.h (_obstack_blank): Rearrange pointer math to avoid
4853 pointing past end of allocated memory; saber complains.
4854 obstack.h: Declare the external functions that we use.
4855 valarith.h: use <string.h>
4856 solib.c (solib_add): lint.
4858 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
4860 * main.c (initialize_main): Default info_verbose to off, now that
4861 symbol reading is fast.
4862 (quit_command): Avoid clobbering exec_bfd while quitting.
4864 * Initial BFD (binary file diddling library) merger:
4865 coffread.c: Change AOUTHDR to struct exe_hdr.
4867 core.c: initialize initialized data at compile time.
4868 (core_file_command): Move from coredep.c, convert to bfd.
4869 (xfer_core_file): Convert to bfd.
4870 exec.c (exec_file_command): use bfd routines.
4872 mips-tdep.c: Remove exec_file_command and friends.
4875 * coredep.c: (fetch_core_registers) Convert core_file_command to
4876 fetch_core_registers.
4877 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
4879 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
4880 (my_bfd_read): More bogosity, which I don't think we call.
4881 (program_name): Remove this atrocity asap!
4883 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
4886 values.c: allocate_repeat_value was not clearing the
4887 optimized_out field.
4888 (value_static_field): minor stylistic fix (wrong macro was used).
4889 valops.c (value_struct_elt_for_address): didn't work for C++
4892 * signame.c (_initialize_signame): Initialize signal names once.
4894 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
4895 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
4896 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
4898 * remote-eb.c: Support user-settable baud rates on the serial port.
4900 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
4902 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
4904 * tconfig/sun3os4: Remove warning about native assembler,
4905 since it also occurs in the xconfig file.
4907 * findvar.c (registers): Allocate some slop after `registers'
4908 to prevent stray accesses from trashing the next variable.
4910 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
4911 on the sun-3, by changing the #ifdef from `sun3' (which is not
4912 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
4913 vars, which happened to follow `registers' in the executable.
4915 * readline/history.c (history_search): Heed gcc-2's advice
4916 and parenthesize && inside ||).
4918 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
4919 tm-29k.c: Insert FSF copyright headers.
4921 * remote-eb.c: Better comments.
4923 * Makefile.dist: Update to 3.91.6.
4924 * TODO: note PREPARE_TO_STORE problem.
4926 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
4928 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
4930 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
4932 * infrun.c (wait_for_inferior, at end): Don't set up
4933 prev_* if the inferior no longer exists.
4935 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
4936 CANNOT_EXECUTE_STACK.
4937 valops.c (call_function): Use it.
4939 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
4941 * inferior.h (PC_IN_CALL_DUMMY): New macro.
4942 infrun.c (wait_for_inferior, 2 places): Use it.
4944 * values.c (value_being_returned): Only use
4945 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
4947 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
4948 right thing for remote-eb.c.
4950 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
4951 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
4953 * blockframe.c: Put get_frame_saved_regs inside #if !defined
4954 (FRAME_FIND_SAVED_REGS).
4956 * findvar.c ({fetch,store}_registers): Check for
4957 REMOTE_{FETCH_STORE}_REGISTER macro.
4959 * findvar.c (get_saved_register): Add argument lval and
4960 change meaning of argument addr.
4961 findvar.c: Change calls to get_saved_register to reflect
4962 new calling convention.
4963 valops.c (value_assign): Use get_saved_register instead of
4964 find_saved_register.
4966 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
4968 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
4969 an (uninitialized) pointer to one. Use "&" when passing it
4972 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
4974 * coffread.c (getfilename): Use DGUX x_offset and x_name if
4977 * coffread.c (symbol_file_command): Put semicolon after
4979 Put safe_to_init_tdesc_context in #if defined (TDESC).
4980 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
4981 coffread.c: #include <sys/stat.h>.
4982 (read_coff_symtab): Typo: in_source_files -> in_source_file.
4983 Add missing ')' in check for "lc%" and friends. Remove
4985 Declare read_one_sym() at top of file.
4986 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
4987 MC68WRMAGIC can have the same value without causing a duplicate
4990 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
4992 * Allow a Makefile to be built without building the
4993 tm and xm file links that screw up builds in subdirectories.
4994 This is done with `config.gdb none', then you can do things
4995 like `make gdb.tar.Z'.
4996 * tconfig/none: Config file for no target system
4997 * xconfig/none: Config file for no host system
4998 * config.gdb: If no TM or XM files are called out by the
4999 host or target file, don't make links for them.
5001 * cplus-dem.c: Add documentation.
5003 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
5004 simple error, so the user's gdb doesn't crash due to some object
5005 file problem (e.g. somebody is rebuilding the file out from under
5008 * printcmd.c (print_address_symbolic): demangle the symbol.
5010 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
5011 Motorola copyrights in it. Make "make gdb.tar.Z" work.
5012 (alldeps.mak): sort and uniq all results from this; duplicates
5013 hose gdb.tar.Z link building. Remove RCS files from
5014 tconfig and xconfig. Add config files for sun386. Add
5015 a few odd files to OTHERS and HFILES.
5017 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
5019 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
5020 Roll version number to 3.91.5. Make lint work in bindir.
5022 * README: Document cross-debugging and new file structure.
5024 * blockframe.c: Lint. Include "value.h" to declare read_register.
5025 (find_pc_partial_function): remove duplicate line.
5027 * command.h: Lint. Declare error_no_arg and dont_repeat.
5029 * tm-news.h: Remove inadvertently duplicated stuff.
5031 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
5032 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
5034 * config.gdb: Allow `config.gdb host target' form. Clean
5035 up previous change that printed bogus messages when you just said
5038 * core.c: #include "command.h" for lint.
5041 * main.c: Remove some casts of enums. Lint.
5048 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
5050 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
5051 read it from memory. This will allow us to save ptrace calls
5052 eventually. Changed caller single_step too.
5054 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
5055 that we aren't going to use, saving many ptrace calls, especially
5056 when watchpointing or single stepping. Use some #define's for
5058 (store_inferior_registers): Ditto.
5059 (core_file_command): Use some #define's for constants.
5061 * tm-sparc.h: Add #define's for some register numbers, so we
5062 can eliminate the use of random constants in sparc-xdep.c.
5064 * stack.c (frame_command, print_frame_info, up_command,
5065 down_command) Remove frame_changed, since it
5066 causes a bug and doesn't seem to do anything useful. In some
5067 places it was used as a flag, in others as a stack level (?).
5069 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
5070 default is to use the portable (vprintf) version rather than the
5072 * xm-news.h (MISSING_VPRINTF): Add.
5074 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
5076 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
5078 * Remove stuff that forces -Bstatic linking of gdb, and warnings
5079 about linking debugged programs -Bstatic in the sun?os4 config
5080 files in tconfig and xconfig subdirectories.
5082 * main.c (main): Remove unreached exit(0) now that we exit
5085 * Create TODO file for online bug list. There are too many
5086 "little" bugs to keep track of on paper.
5088 * Change Projects file to refer to bug-gdb@cygnus.com
5089 rather than kingdon@ai.
5091 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
5093 * Makefile.dist (VERSION): 3.91.4 now.
5095 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
5096 (condense_misc_bunches): Add sanity check that misc_count is
5097 the same as the number of symbols in the bunch.
5099 * coffread.c: rename init_misc_bunches. Pass an argument
5100 to condense_misc_bunches (a zero).
5102 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
5103 every time we are called; don't rely on our caller to do it.
5104 (add_file): Remove call to init_misc_bunches.
5106 * mipsread.c: Only warn, don't error, if unknown symbol types.
5107 This keeps an old gdb from falling on its face if it sees newly
5108 extended symbol info. Rename init_misc_bunches.
5110 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
5112 * Merge in changes from Per Bothner for DECstations and other
5113 MIPS stuff. The rest is Bothner speaking:
5115 The next message is a merger of Alessando Forin's mips port with
5116 mine. I've tried to use my good if biased judgment to get
5117 the best of both. It *does* need testing.
5119 Some of the changes are general, *not* mips-specific.
5122 Didn't believe in little-endian bit order.
5123 There are still inconsistencies about whether flags
5124 like BITS_BIG_ENDIAN are integer (#if ...) or
5125 boolean (#ifdef ...). I tried to paper over them.
5127 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
5128 Moved some misc_function code that was common to
5129 {dbx,coff,mips}read.c to symtab.c.
5130 In the process, I think I cleaned things up a bit.
5131 At the same time, moved obsavestring and obconcat to symtab.c.
5134 Removed obsolete condense_addl_misc_bunches (use
5135 condense_misc_bunches(1) instead).
5138 Needed to include <sys/dir>, at least on DECstations.
5140 valops.c, mips-tdep.c, tm-mips.h:
5141 Added PUSH_ARGUMENTS macro to support funny argument-pushing
5142 conventions (when STACK_ALIGN is insufficient).
5143 Needed on mips, where doubles need 8-byte alignment,
5144 but ints only need 4.
5147 Removed cruft that was not being used.
5148 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
5151 Print $ before register-names (I think that makes things a little
5153 Never print two instructions, even if one delays.
5154 Removed hex-disassemble set_cmd. (This is not mips-specific,
5155 so I think the argument is whether it is generally worthwhile or not.
5156 I'm inclined to think not, given how easy it is to
5157 convert between radixes in gdb.)
5160 This is basically Alessando's code.
5161 It doesn't use obstacks; I changed it to use obstacks
5162 in a few minor places where using malloc causes a
5163 memory leak. (Probably, more places could/should be changed.)
5164 I added record_misc_function where it was missing.
5165 In symbol_file_command and add_file_command, I tried
5166 to make the code consistent with more recent versions.
5167 Minor sylistic changes in parse_procedure.
5168 Make a .gdbinfo. psuedo-symbol point back to the real
5169 procedure symbol (using the isym field).
5172 This is basically from my port, but with a lot of details
5173 and a number of routines merged in from Alessando's version.
5174 I basically used my code "raw" backtrace (use heuristics
5175 from the actual code, rather than symbol table info) - though
5176 the idea is Alessandro's. I feel my code is a little cleaner
5177 here, particularly in being a little more flexible, such as being
5178 able to handle gcc-produced code (which it now can).
5179 It also doesn't do frame caching (which is not useful
5180 more recent gdb versions).
5181 I also used my code for push_/pop_dummy, more or less.
5182 I tried to incorporate AF's code for testing sigtramp
5183 while backtracing; I probably got it wrong.
5184 Added mips_print_register, which tries to scrunch as much
5185 information as possible on a screen...
5186 Removed the skip-prologue set_cmd. As with hex-disassemble (see
5187 under mips-pinsn.c), I don't see anything mips-specific here,
5188 and I don't see it being all that useful anyway.
5191 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
5192 Use more register names (rather than hard-cases numbers).
5194 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
5196 * Hack up 3.90.11 changes:
5198 * Makefile.dist (depend): parameterize $(GCC).
5199 Add solib.c and solib.o.
5200 (readline): Fix vpath for both absolute or relative SRCDIR.
5202 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
5203 Also, let the part I didn't understand at least compile so
5204 I can test the rest. FIXME.
5206 * dbxread.c: Fix thinko using strcmp.
5207 (init_psymbol_list): declare static.
5208 (partial_symbol_file_open): Comment cleanups better, avoid
5209 cleaning up the string table since the caller will do that.
5210 Move the stat for mod time into symbol_file_command, temporarily.
5211 (There should be a mod time for each symbol file, eventually,
5212 to control its rereading. FIXME.)
5214 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
5215 SunOS, which gives error for shared libs otherwise. (From
5216 Schaefer, probably FIXME needs work for portability.)
5218 * solib.c: Move #include "param.h" to work.
5219 Lowercase all the Uppercase Letters In the Messages.
5220 (find_solib): Clean up inferior_so_name for debug printouts.
5221 Allow no argument, to mean all shared libraries.
5223 * symmisc.c: include param.h to get CLEAR_SOLIB.
5225 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
5227 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
5228 to 3.90.11. ChangeLog entries below are from this.
5230 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5234 * Makefile.dist (HFILES): Add tm-sunos.h.
5236 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5240 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
5242 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
5244 * sparc-opcode.h Added single-operand version of rett.
5246 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5248 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
5249 Put parens around gcc_p in expansion.
5251 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5253 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
5255 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5257 * Changes for Sun shared libraries:
5258 blockframe.c (find_pc_partial_function): If a non-text symbol
5259 is found, set *address = pc - FUNCTION_START_OFFSET.
5260 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
5261 Disable breakpoints instead of giving an error.
5262 source.c (select_source_symtab): Initialize cs_pst.
5263 symmisc.c: Call CLEAR_SOLIB if defined.
5264 symtab.h: Make text{low,high} CORE_ADDR not int.
5265 (psymtab): New field addr.
5267 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
5268 (record_misc_function): Give correct type for N_DATA symbols.
5269 (condense_misc_bunches): do "misc_function_count = j" regardless
5271 Take code which is shared between symbol_file_command and
5272 add_file_command and put it into partial_symbol_file_{open,read}.
5273 Split add_file_command into add_file_command and add_file.
5274 Make psymtab_to_symtab read in the string table if the file
5276 Two new parameters to read_dbx_symtab and start_psymtab.
5277 tm-sunos.h: New file.
5279 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5281 * infcmd.c: Change cont_command to continue_command and "cont"
5284 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5286 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
5288 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
5290 * values.c (USE_STRUCT_CONVENTION): Check for structures of
5291 size 1,2,4,8 rather than size < 8.
5293 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
5294 as necessary, not just once.
5296 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
5298 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5300 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
5302 * tm-news.h: Add CALL_DUMMY_*.
5304 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
5306 * config.gdb: In list_host, list_target, use ${i}, not $i.
5308 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5310 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
5312 * sparc-opcode.h: Change all store floating-point state register
5313 instructions to have the right match & lose fields.
5315 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5317 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
5319 config.gdb: If srcdir != ., create readline directory and
5320 copy a makefile into it.
5322 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
5323 consistency with POSIX.
5325 * breakpoint.c (bpstat_stop_status): Disable watchpoint
5326 when we exit its exp_valid_block.
5328 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
5330 * Makefile.dist: Bump version to 3.91.3.
5332 * Clean up handling of breakpoint commands (somewhat).
5333 Prompted by Tiemann bug report "cont 10" doesn't work any more.
5335 inferior.h: Add breakpoint_proceeded to inferior status struct
5336 and globals; save it and restore it.
5337 (clear_breakpoint_commands): Cleanup, remove old #define.
5339 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
5340 (save_inferior_status, restore_inferior_status): handle it also.
5341 (proceed): Remove earlier code that set breakpoint_proceeded.
5342 It is now set only in clear_proceed_status.
5343 (clear_proceed_status): Cleanup, use bpstat_clear rather
5344 than clear_breakpoint_commands. No callers need the stop_bpstat
5345 between clear_proceed_status and proceed.
5347 infcmd.c: Add breakpoint_proceeded definition and comment.
5348 (cont_command, jump_command, signal_command): Move call to
5349 clear_proceed_status right next to call to proceed.
5351 breakpoint.c (bpstat_do_actions): Avoid clobbering our
5352 caller's argument while running down the chain of breakpoints.
5353 Use new variable "breakpoint_proceeded" to determine when
5354 a command that it executes moves the inferior past the
5356 (bpstat_clear): Handle NULL argument.
5357 (bpstat_clear_actions): Avoid useless call to
5358 breakpoint_auto_delete.
5359 (delete_breakpoint): Clean up bpstat's that are pointing to
5360 the deleted breakpoint from the stop_bpstat chain.
5361 (breakpoint_auto_delete): Simplify.
5363 * Clean up handling of EOF, error on stdin, etc. This was
5364 prompted by a network problem that caused gdb to go into an
5365 infinite loop filling up its malloc'd memory.
5367 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
5368 not clear_breakpoints_commands, which is now gone.
5369 (main): If command_loop returns (e.g. from EOF on stdin), do
5370 a quit_command (looping back to command_loop if quit_command
5371 doesn't really quit).
5372 (command_loop): check result from command_line_input and
5373 exit if it returns NULL, rather than passing the NULL to
5375 (gdb_readline): Free malloc'd result space before returning
5378 * utils.c (query): Handle C-d to mean "yes", just as if the
5379 input was not a terminal. Also avoid infinite loop if EOF
5380 occurs in mid-input-line before newline. This allows
5381 query to be used at EOF on stdin with reasonable results.
5383 * infrun.c (proceed): Set breakpoint_proceeded.
5385 * values.c (value_as_long): Avoid infinite recursion for enums.
5386 (_initialize_values): Fix typo in help msg (kingdon).
5388 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
5389 RL_LIB for linking. This allows -lreadline for linking
5390 and nothing for dependencies, once readline is a real library.
5392 * config.gdb: Jim Kingdon: give useful error message if the
5393 host or target type is not recognized.
5395 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
5396 it just defines it. Dumb, but deal with it.
5398 * Jim Kingdon suggests:
5399 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
5401 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
5403 * Makefile.dist (VERSION): Bump version # to 3.91.2.
5405 * Clean up Bothner's changes.
5407 * blockframe.c (clear_pc_function_cache): New function.
5408 * blockframe.c: remake cache_pc_function_* static.
5409 * dbxread.c (symbol_file_command): remove references to
5410 cache_pc_function_* variables.
5411 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
5412 * printcmd.c: Avoid kludging a global variable (addressprint)
5413 to avoid printing the address of a string twice. Instead,
5414 pass the format letter 's' down low enough that it can be seen
5415 to avoid this problem.
5416 (print_formatted): Pass format arg to value_print.
5417 (restore_addressprint): Remove function.
5418 (do_examine): Avoid hacking addressprint, cleanups and such.
5419 (print_frame_args): Add a comment to a Bothner change.
5420 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
5421 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
5422 to wipe out the values cached in blockframe.c.
5423 * symtab.c (find_method): Add comment saying how big you must
5424 allocate to be "big enough". Per being terse again.
5425 * valprint.c (val_print): Handle format letter "s" to print
5426 strings without addresses. Add comment to vtbl printing code
5427 which casts with wild abandon. Rearrange reference-printing
5429 @0xaddr: value (print w/addressprint)
5430 value (print w/~addressprint)
5431 @0xaddr (parameter lists w/addressprint)
5432 or nothing (parameter lists w/o addressprint)
5434 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
5436 * Merge more changes from Per Bothner:
5438 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
5439 annoying) that I tried to improve it. Here are my suggestions.
5441 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
5444 Do automatic de-reference when taking the address of a reference.
5446 Don't deref_ref when printing parameter lists.
5448 More attempts at treating refernences properly.
5450 In val_print, if deref_ref==0, don't print dangling " = ".
5452 Add COERCE_REF macro, which de-references an REF.
5454 * Merge changes from Per Bothner:
5456 * Fixed (Sony news)-specific configuration problems.
5457 * Fixed other problems with using vanilla pcc and libc (enum problems;
5458 assumption that vsprintf exists).
5459 * Some major speed-ups (finc_pc_partial_function now caches a match;
5460 parsing avoids duplicate symbol_lookup calls).
5461 * Changed handling of baseclasses (no longer use baseclasses field
5462 of struct type, use the first n_baseclasses fields instead).
5463 * Various minor changes/fixes, most C++-related.
5466 Cache the most previous match from find_pc_partial_function.
5467 (Save both low and high ends of matching function's pc range.)
5468 This speeds up the loop of infrun.c:wait_for_inferior quite
5469 a bit, and makes step/next commands much zippier.
5471 Added an enum->int cast (otherwise, some compilers barf).
5473 No longer set baseclass offset to 0, since multiple
5474 inheritance now mostly works.
5475 Added a number of casts, to shut up compiler warnings
5476 (after stabs where made enums, not ints).
5477 When discarding a symbol table (in symbol_file_command),
5478 must clear the cache introduced in blockframe.c.
5479 Don't convert $vtbl_ptr_type to vtbl any more.
5480 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
5481 Mask off sign bit emitted by g++ for virtual table offset.
5482 Set voffset to -1 (not 1) for static member functions.
5484 Changed parsing/lexing of names to avoid doing symbol lookup twice
5485 (once when lexing to determine symbol class, once for real).
5486 Now only call symbol_lookup once. Fields of 'this' win especially big.
5488 Subpress printing addr twice in the case of 'x/s addr'.
5490 lookup_basetype_type is no longer used.
5491 Add find_methods as recursive helper function to decode_line_1.
5492 This allows multiple inheritance to work.
5493 Also, once one or more matches has been found, do not look in
5494 base-classes. (Baseclass methods would be overridden, anyway.)
5496 Removed baseclasses array in struct type.
5497 Instead of using baseclasses[i], use fields[i-1].
5498 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
5499 Changed sign convention of voffset (previous was inconsistent).
5501 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
5503 Used to assume existence of vsprintf. Re-written to not need it
5504 if HAVE_VPRINTF is undefined.
5506 typecmp was too pessimistic. Made it less so.
5508 Don't print space after address.
5509 If vtable points to a misc symbol (with 0 offset), print it,
5510 since that indicates the actual class of the object.
5511 Changed ype_print_derivation_info to use new inheritance
5512 scheme (without baseclasses vector).
5514 In value_primitive_field, fixed some bugs left over from previous set of fixes.
5515 Also, changes needed because TYPE_BASECLASSES were removed.
5517 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
5519 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
5522 If there is no path set, and the symbols don't indicate what directory
5523 a file was compiled in, look in the current directory. But either
5524 a path or a known compilation directory will prevent this.
5527 Three independent bug fixes:
5528 * Remove the #if 0 block that breaks some stuff.
5529 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
5530 adapt gdb to either SunOS 4.0.* or 4.1.
5531 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
5534 Instantiate the class T when looking for methods in it. (Tiemann@sun)
5537 (type_print) Demangle the name being printed.
5538 (type_print_base) Handle botched demangling without coredump (tiemann).
5541 (check_stub_method): Document routine.
5542 (tiemann) fix bug for no-arg functions
5543 Avoid clobbering beyond end of malloc'd storage.
5544 Terminate the argument list properly.
5546 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
5548 * Changes merged by John Gilmore:
5551 In breakpoint_1, use new print_address_symbolic instead
5552 of find_pc_partial_function. (This forces use of assembler-level
5553 addresses, and avoids misleading non-mangled source-level names.)
5555 Generalize ansi argument such that -1 means skip arglist totally.
5556 Removed global variable print_ansi_qualifiers (which made
5557 code non-reentrant), in favor of extra explicit arguments
5558 to internal routines.
5560 Add new helper function print_address_symbolic.
5561 Use find_pc_misc_function instead of find_pc_partial_function
5562 (since we want assembler-level symbols here).
5564 Print unknown function as just "f (...)", not "f (...) (...)".
5565 Use new fputs_demangled explicitly.
5567 Fixed a typing violation (problem: value.h cannot be imported
5568 without renaming many variable in this file).
5569 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
5570 decode_line_1: Moved forward some never-reached code.
5571 Made decode_line_2 skip function prologues correctly.
5573 fputs_filtered should not demangle by default.
5574 Add new fputs_demangled to demangle on demand..
5576 Change value_struct_elt to use value_primitive_field (using recursive
5577 utility function search_struct_field). This allows foo.bar to work
5578 for multiple inheritance (so far only for data fields).
5579 Change check_field in the same way (recursive helper function
5580 to support multiple inheritance).
5581 (Note: there are more of these problems that I haven't fixed.
5582 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
5583 value_of_this: 'this' symbol name is now just "this", note "$this".
5585 Don't print static members.
5586 Avoid printing "members of <type>" if there are none.
5587 Simplified type_print_derivation_info by merging duplicate code.
5588 Remove useless blank lines in type_print_base (ptype command).
5590 Added declaration of new routine value_primitive_field.
5592 Added value_primitive_field which is generalized version of
5593 value_field that can handle multiple inheritance (non-zero offsets etc).
5594 Re-implemented value_field to call value_primitive_field.
5596 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
5598 * infcmd.c -- insert else to avoid 'delete env' coredump when you
5599 delete the whole environment. Karl Berry reported the bug.
5600 * source.c - fix openp to avoid //'s in filenames, which
5601 trigger an Emacs bug causing it to not be able to find files
5602 when running gdb in a window.
5603 * dbxread.c - zap the #if 0 that botches the add-file code.
5604 It seems to work a lot better without all the code commented out.
5606 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
5608 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
5611 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
5613 * Makefile - added a ${CFLAGS} to a couple of entries,
5614 added remote-sa.sparc.c
5615 * added remote.sa-sparc.c, a modification of remote.c
5616 which conducts a dialog directly with the SparcStation prom.
5617 * breakpoint.c, infrun.c, sparcdep.c added
5618 remote_insert_breakpoint(), and remote_remove_breakpoint()
5619 to breakpoint.c instead of directly writing breakpoint instructions.
5620 * sparcdep.c on remote_debugging,there is no need
5621 to remove signle step breakpoint instructions.
5622 * main.c added "-epoch" flag and "int epoch_interface" to main.c
5624 * printcmd.c - epoch interface sends lisp expressions to open up
5625 epoch windows on inspection.
5626 * valprint.c - added arrayprint, and addressprint and made adding
5627 format controls easier
5628 * wait.h added a couple of undef's because we were getting
5629 complaints about WSTOPSIG and WTERMSIG begin redefined.

5725 step_resume_break_address != NULL, even if another_trap.
5726 If trap_expected and we enter sigtramp, then set up a
