8 Pass .reg virtual memory address to fetch_core_registers to help
9 it find the registers in the core-file header.
10 * coredep.c (fetch_core_registers): Take new argument, use it,
11 and pass it to register_addr to locate the block of registers.

14 * dbxread.c (read_dbx_symtab, process_one_symbol): Handle
15 Sequent N_FN_SEQ like everybody else's N_FN.
17 * main.c: Circumvent SCO cc bug with #if !!defined(USG).
18 * tm-i386v.h: #endif guck.
19 * xconfig/i386*: Remove -Dgetpagesize()=4096 kludge.
20 * xconfig/i386sco: Add HAVE_STRSTR to avoid ANSI bdeath.

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

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

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

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

230 * language.c (set_language_command): Print useful help message,
231 and restore the language string after giving help.
232 * valprint.c (typedef_print): Print typedef in C or M2.
233 * symtab.c (list_symbols): Use it.
234 * main.c (main): Avoid any output before (gdb) prompt when -q.
235 * language.c (set_language_command): Handle errors by restoring
236 the language string to its current state (fix from A. Beers).
237 * doc/gdbint.texinfo: Roll in information from README. Rearrange
238 "how to install" and "how to print the doc" stuff so it drops
240 * configure.in: Rename rtpc CPU to romp to match config.sub.
241 * README, WHATS.NEW, TODO: Update for gdb-4.1.
243 Fri Sep 20 17:39:14 1991 Roland H. Pesch (pesch at cygnus.com)
245 * doc/gdb.texinfo: Updates from ChangeLog. set/show write,
246 autoloading shared libs, copyright etc on GDB startup, clean up $_
247 and $__ index refs, set/show listsize and related updates to list
248 cmd. New host/target configs.
250 Fri Sep 20 15:46:00 1991 Roland H. Pesch (pesch at cygnus.com)
252 * doc/Makefile: generate aux version-no file doc/gdbVN.m4
253 from main Makefile.in version definition
254 doc/gdb.texinfo: use version recorded in doc/gdbVN.m4 for current
256 Makefile.in (setup-to-dist): generate doc/gdbVN.m4
258 * doc/gdb.texinfo: merge new language-switching and lang-specific
261 Fri Sep 20 15:00:57 1991 Per Bothner (bothner at cygnus.com)
263 * mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
264 compilers (which may lack stddef.h).
266 Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com)
268 * dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and
269 N_WARNING are the same except for the N_EXT bit, so just use their
270 values alone, rather than OR-ing them with N_EXT.
272 Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com)
274 * mipsread.c (parse_lines): Deal with negative extended line
277 * c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid
278 global symbol conflicts.
280 Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
282 * .gdbinit: Move 'set complaints' to top, so it runs even in
283 case we aren't debugging GDB.
284 * language.c (_initialize_language): Fix type check and range
285 check documentation strings.
286 * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
287 language.c can use it. (Though language.c should really not be
288 handling warnings/errors the way it does, FIXME.)
289 * symtab.c (lookup_primitive_type): const lint.
291 Bugfix from Peter Schauer:
292 * source.c (lines_to_list): Make signed, to avoid comparison
293 going unsigned and complaining that -3 is too high for 21 lines.
294 * stack.c (lines_to_list): Ditto.
296 Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
298 * Makefile.in (HFILES): Add minimon.h.
299 (VERSION): Roll version number to 4.0.95.
300 (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
301 New rules for building distributions. Normal distribution
302 is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
303 one level up from here; it calls make-proto-gdb.dir to build a
304 directory `proto-gdb' which is an image of the release. The old
305 `gdb.tar.Z' rule still works too.
306 * config.sub, configure: Roll in latest from ..
308 Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
310 * doc/gdbint.texinfo: Reorder contents; reorganize new-host,
311 new-target, and new-config chapters; fix minor typos; come closer
312 to usual GNU markup conventions for @file @samp @code @var.
314 Thu Sep 19 17:04:12 1991 Per Bothner (bothner at cygnus.com)
316 Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
317 * mipsread.c (parse_partial_symbols): Enter the name of all
318 structs/unions... into the psymtab so we can access them if the
319 symtab is not read in.
320 * mips-tdep.c: Remove some unneeded #includes.
321 * xconfig/dec3100: Add HAVE_STRSTR.
323 Thu Sep 19 15:14:23 1991 John Gilmore (gnu at cygnus.com)
325 * Makefile.in: Circumvent Sun Make bug on *-exp.tab.o.
326 * c-exp.y, m2-exp.y: Lint.
327 * m2-exp.y: Avoid using yytname[] which is a Bison-ism.
328 * valprint.c (val_print_fields): Check for stub type.
329 * mipsread.c (_initialize_mipsread): Avoid using
330 builtin_type_void at initialize time.
331 (mipscoff_symfile_read): use it now.
333 Wed Sep 18 15:55:51 1991 John Gilmore (gnu at cygnus.com)
335 Merge multiple-language support, and partial Modula-2 support,
336 from Andrew Beers <beers@cs.buffalo.edu>.

432 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
434 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
435 entries are enclosed herein. Not all of these changes
436 have been merged into the master GDB sources -- check the
437 ChangeLog above here for the merge log.
439 Mon Jun 3 17:05:45 EDT 1991
441 m2-exp.y Created. Tested outside of GDB for a few days. Proper
442 operators were added, C specific operators and tokens
443 removed. yylex() revamped to some extent. Still things
444 missing from the grammar, such as sets.
445 Tested for two weeks in GDB v3.5.
447 Tue Jun 11 17:23:48 EDT 1991
449 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
450 so they are built-in. Sort of a hack.
452 Fri Jun 14 12:53:51 EDT 1991
454 m2-exp.y Added range checking for numeric constants. Any numeric
455 constant is assumed to be of builtin type INTEGER unless:
456 (1) it is octal or hexadecimal, in which case it is a
457 CARDINAL; (2) it is too big to fit into an INTEGER, in
458 which case it is a CARDINAL.
459 eval.c Added simple range checking for +, -, and * on integers.
460 Doesn't work very well for *, since 6 * 1,000,000,000 =
461 1,705,032,704, which fails the simple test of result >=
462 first_operand, no matter in what order the operands are.
464 Tue Jun 18 14:11:30 EDT 1991
466 Broke the parser into parts, one containing the C grammar and the other
467 containing code to be shared by all of the grammars.
469 The following files no longer exist:
474 The following files were added:
476 c-exp.y (The C grammar)
477 m2-exp.y (The Modula-2 grammar)
478 parser-code.c (Code that is shared by the above grammar)
482 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
483 now necessary to use the Bison compiler compiler, since it
484 will generate function/variable prefixes other than yy.
486 Tue Jun 18 16:47:49 EDT 1991
488 symtab.[ch] Added the external variable working_lang, than holds the
489 value of the current working language.
490 Added the ennumerated type language_mode, with the values
491 language_auto and language_manual, the former meaning that
492 GDB sets working_lang as needed, and the latter meaning
493 that the value of working_lang is totally under user
495 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
496 REAL, BOOLEAN and CHAR. Also added the type codes
497 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
498 utils.c Added set_language_command and show_language_command to
499 implement the GDB support commands "set language" and
501 expression.h A number of identifiers were added to the type exp_opcode
502 to facilitate Modula-2 builtin functions, integer
503 division, and array indexing.
505 Wed Jun 19 13:25:58 EDT 1991
507 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
508 if the language specified by working_lang requires the use
509 of strict typing of expressions. Eventually, even this
510 will be able to be changed by the user.
511 Added the macro RANGE_CHECK, which evaluates to non-zero
512 if the language specified by working_lang requires the
513 checking of a value against the domain of its type.
514 Eventually, even this will be able to be changed by the
516 language.[ch] Predicates involving types (simple_type, ordered_type,
517 same_type, integral_type, numeric_type, character_type,
518 boolean_type, float_type) are added. These predicates are
519 based on the current value of working_lang, and are handy
522 Wed Jun 19 15:39:34 EDT 1991
524 eval.c Added the function type_array_rank which computes the rank
526 valarith.c Added the funtion value_bool, which when given a integer
527 value.h value (ie. struct value *) as an argument, it returns a
528 boolean value (ie. struct value *) true if that integer
529 is non-zero, and a boolean value false otherwise.
530 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
531 will print out properly.
533 Wed Jun 19 16:36:34 EDT 1991
535 valops.c Added the function value_capitalize, which returns it
536 value.h argument capitalized if its argument is a lowercase
537 letter, or the argument unchanged if its argument is not a
539 valarith.c Added the function range_check_p, which returns non-zero
540 value.h if its value argument is between the integral bounds upper
542 Added the function range_check_enum_p, which makes sure
543 that its value argument is a valid member of the domain of
545 Added the function range_check_range_p, which makes sure
546 its value argument lies between the upper and lower bounds
547 of its type argument, which must be a ranged type.
548 Added the function check_array_index, which range and type
549 checks an index of an array.
550 Added the function value_multi_subscript, which computes
551 array[idx1,idx2...idxN], given a value array and an array
552 of values representing indicies.
553 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
554 unpack_long to work with TYPE_CODE_BOOL and
557 Wed Jun 19 18:04:08 EDT 1991
559 symtab.c Stored pervasive types in a structure and make
560 lookup_pervasive_type() a lookup function that was based
561 on working_lang. If lookup_pervasive_type() returned
562 non-zero, then that value was returned (a fix, since
563 before it simply wouldn't return the pervasive type.)
564 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
565 non-zero if the language specified by working_lang means
566 "conversion" when it says "cast".
567 valops.c Added the function value_real_cast(), which performs a
568 value.h *cast*, not a *conversion*, which is what value_cast()
569 does when it can. In particular,
570 value_cast(<float_type>,4) = 4.0, while
571 value_real_cast(<float_type>,4) = some mess.
572 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
573 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
574 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
575 and MIN on integral types. *NOTE*: These are currently
576 hardcoded to work only if there are 8 bits per storage
578 eval.c Made logical functions call value_bool to return a
579 properly typed boolean value, based on working_lang.
581 Thu Jun 20 11:55:27 EDT 1991
583 valprint.c Types now print out in a Modula-2 fashion. This works for
584 the cases when the type is printed out step-by-step, that
585 is, it doesn't work when the name of a structured type
586 (which includes the keyword "struct", etc.) is simply
588 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
589 since type specifications in C and Modula-2 are very
590 different. The C printing of a type is very recursive,
591 whereas in Modula-2 it is generally very simple. C has
592 type prefixes and suffixes, which have no real analogue in
593 Modula-2. Maybe type_print() should call a language
594 specific type printer. This is also advantageous if we
595 compile GDB to exclude some of the languages. We'll just
596 leave those functions out.
598 Thu Jun 20 16:57:10 EDT 1991
600 dbxread.c When reading the complete symbol table in (via
601 psymtab_to_symtab()), the number and types of function
602 arguments are added to a function type. define_symbol()
603 calls add_param_to_type() to accomplish this.
604 Assumption: when we come across a function definition
605 (N_FUN symbol with an 'f' or 'F' in the name), its
606 arguments will appear before another function definition.
607 When a function is found, a pointer to its type is placed
608 in the global in_function_type. Changes that
609 add_param_to_type() makes are to this global.
610 valprint.c The type of a function now includes (for Modula-2) the
611 types of its parameters.
612 eval.c Type checking and a check for the proper number of
613 arguments is now done for function calls. Not sure of the
614 impact this has on C++ member function yet.
616 Thu Jun 20 19:58:48 EDT 1991
618 valprint.c Rewrote the type printer. Broke it into two language
619 specific parts, adding the functions type_print_m2() and
621 An unfortunate consequence is this: if you debugging a C
622 program in Modula-2 mode (why?), info types does not work
623 well with regular expressions, since the types are printed
624 out in Modula-2 terminology, but stored in C terminology.
625 language.[ch] Added the functions new_type_last(), type_keyword(), and
626 type_sep() to aid in the printing of typedefs.
627 symtab.c Made the printing of typedefs as language independent as
628 possible through calls to new_type_last(), type_keyword(),
631 Fri Jun 21 11:50:26 EDT 1991
633 dbxread.c Check all incoming ennumerated types. If it looks like
634 Modula-2's BOOLEAN type, then change the type_code of the
635 type to TYPE_CODE_BOOL so we can process it as a boolean
637 valprint.c Replaced some of the 0x%x with calls to sprintf and
638 hexformat() in val_print().
639 language.[ch] Added the function hex_to_string(), which converts its
640 integral argument to a hexadecimal number (format is
641 language based) and returns the result as a string.
643 Mon Jun 24 12:25:07 EDT 1991
645 valprint.c Some functions call type_print_1() directly, instead of
646 value.h using type_print(), so they can specify where (column) to
647 print things. Since type_print() takes care of language
648 dependence, that needs to be called first. Added a
649 parameter depth to type_print() (so it is now like
650 type_print_1). Changed type_print to type_print_at, and
651 made type_print a macro that passes a depth argument of
653 symmisc.c Changed all calls to type_print_1 to calls to
655 Makefile.dist Made it possible to build GDB for a specific set of
656 depend languages. Do this by passing a definition for the macro
657 LANGS to make. LANGS should be a string containing a
658 space-separated list of language names (ie. LANGS="c m2").
659 The default is to build all languages. Note that grammar
660 files must follow the naming convention of <lang>-exp.y.
661 gdb.lang This holds the current value of the LANGS macro. It is
662 examined every time make is called, and is updated if
664 eval.c Added #ifdef _LANG_<lang> to these files.
665 expread.c Still need to add them to dbxread.c and coffread.c.
673 Mon Jun 24 16:33:11 EDT 1991
675 language.[ch] Added the functions hexformat_pre() and
676 hex_to_string_pre(), which take a prefix argument to
677 include in the format string. Thus, hexformat_pre("08") will
678 return "0x08x" (if the working language is language_c).
679 Made hexformat() and hex_to_string() calls to the above
680 with "" as the prefix argument.
682 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
683 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
684 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
685 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
686 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
687 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
688 valprint.c, vax-pinsn.c
690 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
691 calls to hexformat() and hex_to_string(). Format strings without
692 the leading "0x" were ignored.
694 depend Updated to take the above into account.
697 Tue Jun 25 15:27:18 EDT 1991
699 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
700 and type_check_t to keep track of the current state of
701 range and type checking.
702 main.c Added the variables range_mode, range_check, type_mode,
703 and type_check to record the current state of range and
704 type checking. Added initialization code to main().
705 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
709 Tue Jun 25 17:57:08 EDT 1991
711 dbxread.c process_one_symbol() updates the variable (enum language)
712 source_lang based on the extension of the filename
713 contained in the N_SO sybmol that started this symtab.
714 When end_symtab() is called, the value of source_lang is
715 put into the language field.
716 stack.c select_frame() sets working_lang (and possibly type_check
717 and range_check) to the language field of the symtab
718 associated with the frame that is selected if working_mode
719 is language_auto. If working_mode is language_manual, a
720 warning is printed and working_lang is not set.
721 language.c Added the function set_type_range(), which sets the value of
722 type_check and range_check (if their modes call for
723 automatic setting) based on the current value of
724 working_lang. A non-zero argument will cause the current
725 settings to be output.
728 Wed Jun 26 14:51:40 EDT 1991
730 eval.c Added range checks on assignment.
731 m2-exp.y Added the grammar for sets to the language. Currently,
732 these do not do anything except print an error message.
734 Wed Jun 26 17:01:04 EDT 1991
736 m2-exp.y Added the ability for parse_number() to parse negative
737 numbers. A global flag is set upon encountering a unary
738 minus. This was done to make, for example, 1 parse as a
739 CARDINAL, and not as an integer, per Wirth's examples in
740 Programming in Modula-2 ed.4.
741 valprint.c Added support for "set radix 2" by then setting
742 output_format to 't'.
743 eval.c Implemented range checking on subrange types. Added calls
744 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
745 Implemented MIN and MAX for ennumerated types. The
746 minimum value of an ennumerated type is defined by Wirth
747 as the first identifier, and the maximum as the last.
748 m2-exp.y Made octal numbers ending with "B" be characters and those
749 ending with "C" be numbers, per Wirth's book. (p. 34)
751 Thu Jun 27 14:11:52 EDT 1991
753 stack.c select_frame() now only sets working_lang, it does not
754 notify the user. If working_mode is language_manual, then
755 a warning is issued once.
756 main.c At the end of each call to execute_command(), working_lang
757 is checked against the local static (enum language)
758 current. If they differ and working_mode is
759 language_auto, the new settings of language, type and
760 range checking are printed out.
761 stack.c Modified frame_info() to include the language of the
762 current frame in the output of "info frame".
763 language.[ch] Added the function language_str() which returns the name
764 of the current language.
766 Fri Jun 28 15:33:14 EDT 1991
768 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
769 the language. INCL and DECL currently cause an error,
770 since sets are not implemented yet. INC and DEC are
771 implemented as PREINCREMENT/PREDECREMENT with one
772 argument, and as ASSIGN_MODIFY with two arguments.
773 eval.c Added type checking to the above cases.
774 value.h Added not_lval_constant to the lval_type ennumerated type.
775 not_lval_constant means that the value is a constant
776 value; that is 3 or 'a' or TRUE, not as in a constant
777 identifier. This is used to help coerce numbers such as 3
778 to either signed or unsigned numbers.
779 valops.c Added the function value_coerce_constants() which coerces
780 constant integers as following: if one is a constant and
781 the other is not, the constant's type is set to the type
782 of the other argument. If both are constants and one is
783 signed, the other is converted to a signed constant.
785 Sat Jun 29 17:26:29 EDT 1991
787 valarith.c Added a better range checker. It now checks range
788 (successfully) on integral operations [+-] (signed and
789 unsigned) for any C sized type. Still does not work well
791 int_in_size() returns an integer that is coerced to fit into
792 specified number of bytes.
794 Mon Jul 1 13:04:14 EDT 1991
796 language.[ch] Added the function binop_result_type(), which returns the
797 builtin (struct type *) type that would be the result of a
798 binop on the two values V1 and V2.
800 Wed Jul 3 19:22:53 EDT 1991
802 source.c Extended source_info() to include the source language in
803 the output from "info source".
805 Fri Jul 5 13:48:52 EDT 1991
807 utils.c Moved the support functions for the GDB set/show commands
808 dealing with language into language.c.
809 language.c Added the function language_info(), which displays info
810 about the current working language, type and range check
811 settings. Called via the GDB command "info language".
812 Added an initialization routine _initialize_language(),
813 that sets defaults for the language, type and range
814 variables and sets up the new GDB commands.
815 main.c Language setup moved to language.c.
818 Mon Jul 8 10:10:22 EDT 1991
820 valarith.c Debugged the range checker for arithmetic. Still does not
821 work for multiplication very well.
823 Mon Jul 8 12:40:37 EDT 1991
825 language.[ch] Added the function value_true() which returns non-zero if
826 its argument represents a boolean true value.
827 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
828 check the truth of an expression.
830 Thu Jul 11 12:51:34 EDT 1991
832 language.[ch] Added the predicate structured_type(), which returns
833 non-zero if the argument is a structured type.
834 Added the predicate pointer_type(), which returns non-zero
835 if the argument is a pointer type.
836 eval.c Added the ability to do addition and substraction on
837 pointers and integers. This case simply bypasses the
840 Thu Jul 11 14:41:42 EDT 1991
843 Added the symbol N_DEFD (0x4a) which is a definition
844 module dependency that is used by the GNU Modula-2
845 compiler and the linker. It is not important to GDB,
846 except that [dbx|coff|mips]read.c should ignore these
849 Fri Jul 12 16:07:00 EDT 1991
851 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
852 0 in val_print(). Also added statements to the else part
853 to coerce type (argument to val_print) to a pointer type
854 if it is an "array of unspecified length".
855 valops.c Added the function value_m2_string(), which returns a
856 (value) value which is a constant string, whose type is
857 (ARRAY [0..n] OF CHAR). The length field of the type
858 structure is set to zero, so it will be interpreted as an
859 "array of unspecified length".
860 stack.c Moved the language/frame mismatch check to
861 main.c:execute_command().
862 main.c The working language is recorded each time
863 execute_command() is executed. If working lang has
864 changed during its execution, then the new
865 language/type/range info is printed out for the user. If
866 the working language does not match the language of the
867 frame, a warning is issued.
869 Sat Jul 13 16:16:39 EDT 1991
871 eval.c Moved all the type-checking stuff for operators to
872 language.[ch] language.c. This is so we can keep language-specific
873 stuff (like for what type operators are defined) in
875 language.[ch] Added the function binop_type_check(), which checks to see
876 if its two (value) arguments are type-compatible with its
877 opcode argument. The opcode should represent an operation
878 involving an operator. Also added the macro function
879 unop_type_check, which calls binop_type_check with a
880 NULL second argument.
881 expprint.c Added Modula-2 operators to the op_print_tab, so info
882 expression.h break works correctly. Also added "op_string", which
883 returns the string corresponding to the (enum exp_opcode)
884 opcode that is its argument.
887 Sat Jul 13 18:26:18 EDT 1991
889 coffread.c Added code to record the type of function arguments with
890 each paricular function. Code is very similar to that
892 dbxread.c Moved add_param_to_type() to symtab.c
893 symtab.[ch] Added function add_param_to_type() from dbxread.c
895 *** NOTE: The above additions have not been tested.
897 Mon Jul 15 12:50:47 EDT 1991
899 langauge.[ch] Added the functions type_error and range_error, which work
900 like error() except if the type/range mode is set to
901 *_mode_warn, then they do not do a return_to_top_level(),
902 but merely print a warning.
903 Also changed [set|show]_[type|range]_command() to support
904 the new "warn" feature.
906 Thu Jul 18 17:50:54 EDT 1991
908 mipsread.c Added code to record the type of function arguments with
909 each particular function. Code is very similar to that
912 *** NOTE: The above additions have not been tested.
914 Fri Jul 19 11:19:10 EDT 1991
916 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
917 UMIN_OF_SIZE, which when given a size of a numeric type,
918 return the maximum and minimum value it can hold. UMAX...
919 and UMIN... return the result for unsigned types.
920 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
921 struct types. They call above macros.
922 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
923 avoid a name conlict with the above.
924 c-exp.y Added range checking on numeric constants in
925 parse_number() for completeness.
926 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
927 return 0 if working_lang is not language_c.
929 Thu Aug 8 14:17:22 EDT 1991
933 breakpoint.c Documentation strings of some commands changed to
934 eliminate the references to the C language where
937 Tue Aug 13 15:48:03 EDT 1991
939 m2-exp.y Added qualified identifiers to the grammar. The semantics
940 are slightly different from those of the GDB operator ::
942 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
943 type_exp, where type_exp is any valid type expression.
945 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
946 printcmd.c Modified ptype_command() so it actually parses the input
947 (necessary for type expressions with scope qualifiers).
948 Added the function ptype_eval() which expects an
949 expression composed of one OP_TYPE element.
950 *.[ch] Replaced all occurences of parse_c_expression with
952 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
954 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
956 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
958 Small fixes from Peter Schauer:
960 * infrun.c (child_attach): Lint.
961 * solib.c (find_solib): Handle shared libs version 2.
963 Small fixes from David Wood:
965 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
969 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
970 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
972 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
973 chars_per_line is at maximum (user typed `set width 0'). Fix
974 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
976 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
978 * coredep.c: include ptrace.h where necessary.
979 * mipsread.c(parse_lines): fix unsigned char problem that was
980 messing up line numbers on SGI's and possibly other MIPS based
982 * infrun.c (child_create_inferior): use better test to check
983 return val from setpgrp().
984 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
985 for sgi/irix support.
987 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
989 * mipsread.c (parse_symbol): Put non-static procedures
992 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
994 Patch together `text_start' and `text_end' for 29K port.
996 * exec.c (exec_command): If NEED_TEXT_START_END, define the
997 variables and set them based on the exec file.
998 * am29k-tdep.c: declare text_start.
999 * valops.c (call_function_by_hand): declare text_end.
1001 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
1002 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
1003 because machines that do this will also have to know to
1004 set NEED_TEXT_START_END. Besides, it was a redundant way to
1006 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
1007 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
1008 NEED_TEXT_START_END.
1010 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)

1014 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
1015 Pass MUNCH_DEFINE to munch whenever we run it.
1016 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
1017 format string; use 0x%x instead.
1018 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
1019 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
1020 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
1021 * inflow.c: Handle `short' process group IDs.
1022 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
1023 and check for ptrace errors.

1026 (read_coff_symtab): Use it to find the text [and absolute?] sections.
1027 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
1028 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
1029 Merge target arm case with other "easy" cases. Add target
1030 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
1031 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
1033 * minimon.h, remote-adapt.c, remote-mm.c: Add.
1034 * munch: Cope with RT/PC putting fns in data segment.
1035 Restore ability to override `nm' by specifying MUNCH_NM.
1036 * xconfig/rtbsd, xconfig/ultra3: New host systems.
1037 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
1038 and remote-adapt. Remove encapsulated coff #define's (the
1039 support should go in BFD, and gdb shouldn't know or care).
1040 * tconfig/a29k-kern: Same, but for remote kernel debugging.
1041 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
1042 * tm-29k.h: Update BADMAG (though it should go away).
1043 Allow the register definitions to be overridden in another
1044 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
1045 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
1046 DUMMY_SAVE_GR96, for handling kernel calling conventions
1047 that use GR64+ rather than GR96+.
1048 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
1049 remote debugging of Ultra3 kernel. Includes tm-29k.h and
1050 overrides various things.
1052 * remote-mm.c (mm_attach, mm_wait): Handle attach like
1053 child_attach does, making a clean stop in the newly attached
1055 * remote-eb.c: Lint.
1057 * coffread.c: Make coffread independent of any particular
1058 variant of COFF. Avoid #include-ing any particular one except
1059 internalcoff.h. BFD now passes key values for symbol reading
1060 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
1061 and the symbol masks and shifts); use them.
1062 Remove obsolete end_of_text_addr.
1064 * exec.c: Remove unused include files.
1066 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1068 * Makefile.in (documentation targets): Pass $(M4).
1069 Bugfix from eggert@twinsun.com (Paul Eggert).
1071 * stack.c (down_silently_command): Check for stack existence.
1073 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1075 * Makefile.in (VERSION): Update to 4.0.3.
1077 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1079 * core.c (core_file_command): Print frame at coredump with
1080 its level number, by calling print_stack_frame.
1081 * frame.h: Add selected_frame_level, print_stack_frame.
1082 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
1083 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
1084 Change print_sel_frame and print_selected_frame callers to
1087 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
1088 * symfile.c (free_named_symtabs): Ditto.
1089 * main.c (main): wrap_here needs an arg.
1090 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
1091 (solib_add): Avoid noise.
1092 (solib_create_inferior_hook): Lint.
1093 (sharedlibrary_command): Move dont_repeat to here.
1094 * utils.c (error): Call wrap_here to force buffered output.
1096 Small patches from Peter Schauer:
1098 * coffread.c (start_symtab): Free any existing line_vector before
1100 (read_coff_symtab): Ditto for type_vector.
1102 * source.c (lines_to_list): New variable, replacing function.
1103 (all uses): Use as variable.
1104 (_initialize_source): Add 'set listsize' and 'show listsize'.
1105 * utils.c (lines_to_list): Remove function.
1106 * stack.c (print_frame_info): Use as variable.
1107 * defs.h (lines_to_list): Remove declaration.
1109 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1111 * breakpoint.c (insert_breakpoints): Restore warning about
1112 the program might be running in another process, but only for
1113 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
1114 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
1116 * utils.c (error): if error_pre_print is set, print the string
1118 * main.c (main, print_gnu_advertisement, print_gdb_version):
1119 Reformat legalese so it always prints, but acts as an "I'm here"
1120 message while symbols are being read. If any errors occur,
1121 print a few newlines to set off the message and start it at the
1122 left margin. Remove mention of "help" command, and don't yak
1123 about symbol reading.
1124 (catch_errors): Error string is now printed first in case of
1126 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
1127 suggest the "help" command.
1129 * Makefile.in (VERSION): Set to 4.0.2.
1131 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
1133 * .gdbinit: Remove useless "rr" command. Set complaints
1134 to 1 for people debugging gdb.
1136 * breakpoint.c, remote-vx.c: Reword strings printed by
1137 catch_errors callers.
1139 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
1141 * WHATS.NEW: "history write -> history save". Doc "write on/off".
1142 (Fix from kenc@viewlogic.com.)
1144 Fix some infrastructure to be able to cope with host and target
1145 machines with different sized basic types (ints, ptrs, etc).
1146 (Idea from pierre@la.tce.com (Pierre Willard).)
1148 * values.c (value_from_longest): Rename from value_from_long.
1149 Handle pointer types as well as integers, so that targets with
1150 different pointer sizes from the host can be accomodated.
1151 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
1152 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
1153 uses of value_from_long to value_from_longest.
1154 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
1155 the correct pointer type to value_from_long{est}.
1157 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
1159 * remote-vx.c: Remove obsolete code for calling functions via
1160 vxworks kludge interface (it referenced value_from_long).
1162 * valops.c (value_string): Find malloc with lookup_misc_func, not
1165 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1167 Make writing to files work properly. (Fixes to BFD are also needed.)
1169 * core.c (core_open): Open file ourselves, read or r/w, depending on
1170 write_files. Use bfd_fdopenr.
1171 * gdbcore.h (write_files): New variable.
1172 * exec.c (write_files): Define variable, add set&show for it.
1173 (exec_file_command): Use write_files to open for read or r/write.
1175 Make shared library reading happen automatically. These changes
1176 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
1178 * inferior.h (stop_soon_quietly): Add to exported variables.
1179 * infrun.c (child_create_inferior): call solib hook, if defined.
1180 (child_attach): call solib hook, if defined.
1181 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
1182 (find_solib): Use lookup_misc_func rather than hand-rolled.
1183 (symbol_add_stub): New stub for catch_errors.
1184 (solib_add): Avoid output if !from_tty. Catch errors rather
1185 than just calling symbol_file_add and bombing.
1186 (solib_create_inferior_hook): Interface with the target process
1187 to let it read and alloc shared libs, then figure out what it did.
1189 * core.c (validate_files): Fix typo, soften warning.
1190 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
1192 * utils.c (fputs_demangled): Avoid duplicate printing if
1193 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
1195 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
1196 (Fix from pierre@la.tce.com (Pierre Willard).)
1198 * main.c (catch_errors): Change argument to a char * from an int,
1199 since a char * can point to a struct full of glop, but an int
1200 is not guaranteed to be able to hold a pointer.
1201 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
1202 breakpoint_re_set_one, breakpoint_re_set): Adapt.
1203 * core.c (core_open, solib_add_stub): Adapt.
1204 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
1206 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1208 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
1209 by adding .NOEXPORT target.
1211 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1215 * Makefile.in (VERSION): Roll to 4.0.
1216 (gdb.tar.Z): Make refcard.ps as well, for shipment.
1218 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1220 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
1223 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
1226 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
1228 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
1229 reflect above name change
1231 * WHATS.NEW: correct pointer to refcard.
1233 * doc/gdb.texinfo: update New Features, Installing
1235 * doc/gdbint.texinfo: add short description of configure +template
1237 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1239 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
1241 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
1243 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
1244 tar file, add dependencies for referenced doc files.
1246 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
1248 * coffread.c, symfile.c, stack.c: saberized.
1250 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1252 * doc/refcard.tex: permuted Essential Commands sec
1254 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
1256 set/show symbol-reloading
1257 default set complaints 0
1259 RET-repeat disabled after prompted long displays
1260 processID (attach) interpretation of 2nd GDB cmdline arg
1262 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
1264 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
1265 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
1266 breakpoint.c, main.c: lint.
1268 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1270 Install new configuration scheme for GDB and friends.
1272 * config.sub: Translate ordinary names to three-part names.
1273 * configure: Use three-part names internally.
1274 * configure.in: Translate three-part names to filenames.
1276 * README, WHATS.NEW: Update for gdb-4.0.
1277 * Makefile.in: Roll VERSION to 3.99.
1279 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
1281 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
1282 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
1283 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
1284 to single structures rather than arrays; when passing
1285 their address, use &. This avoids trouble with bdead compilers.
1286 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
1287 instead. This avoids portability headaches.
1288 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
1290 * source.c (open_source_file): Avoid ANSI const bdeath by
1291 skipping declaration and then casting result value.
1292 * tm-hp300bsd.h: Clarify comment.
1293 * utils.c (strstr): Result is const char *; ANSI bdeath.
1294 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
1295 since system include file defines it differently from "defs.h",
1296 though the two are equivalent for our purposes.
1297 * tconfig/hp300bsd: Add m68k-tdep.o.
1299 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1301 * tconfig/sun*4: Remove warnings about system assembler.
1303 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1305 * mcheck.c: Avoid warning about undeclared abort fn.
1306 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
1307 it causes recursive calls to error() when used in cleanups.
1308 To do so requires that we make it a function, so we do.
1309 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
1310 * utils.c (do_cleanups): Remove the current cleanup from the
1311 chain *before* calling it, in case error() is called from it.
1312 The result won't be pretty, but won't be an infinite loop either.
1314 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
1316 * dbxread.c (read_struct_type): Grok anon structs for C++.
1317 (vb_name, vptr_name): Null terminate these strings.
1319 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1321 Minor bug fixes from BSD Net2 gdb:
1323 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
1324 returns 0, there is no previous frame.
1325 * breakpoint.c (commands_command): If !from_tty, don't call
1326 input_from_terminal_p().
1327 * dbxread.c (record_misc_function): Speed up slightly.
1328 (compare_psymbols): Ditto.
1329 * infcmd.c (do_registers_info): Take a second argument to
1330 determine whether to print float registers. "info registers"
1331 does not do so anymore. "info all-registers" does, now.
1332 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
1334 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
1335 * inflow.c (initialize_inflow): Set tflags_ours correctly.
1339 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
1340 executing_breakpoint_commands if we are interrupted by error.
1341 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
1342 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
1343 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
1344 catch_errors() so we can setup the frame regardless of whether
1345 the shared libs work.
1346 * ieee-float.c (double_to_ieee_extended): Get exponent from
1347 right place in little-endian systems. From John Carey.
1349 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1351 * main.c: Remove unused terminating_signals and catch_termination().
1352 (long_options): Terminate with a zero element.
1353 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
1354 (gdb_readline): Make call-compatible with readline.
1355 (init_signals): Improve comments re vfork vs. signal.
1357 * utils.c (prompt_for_continue): Use new gdb_readline().
1358 If we prompt for continuation, we don't let CR repeat the previous
1359 command, once we get back to a prompt. It's too easy to keep
1360 hitting CR, expecting "--more--" prompts, and have some long
1361 command start repeating on you.
1363 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1365 * blockframe.c (frameless_look_for_prologue): Speed up by
1366 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
1367 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
1368 Define two variants, one faster.
1369 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
1370 and return zero, rather than giving an error.
1371 (setup_arbitrary_frame): Initialize the PC in the new frame.
1372 (skip_prologue): Add a second arg saying whether we're just
1373 checking for a frameless function or not.
1375 * core.c (core_open, core_close, core_xfer_memory): Move
1376 section table pointers and bfd* into the target_ops.
1377 (core_open): Allow errors in shared lib reading, etc.
1378 (core_files_info): Describe shared library sections.
1380 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
1381 exec_files_info, set_section_command): Move section table
1382 pointers and bfd* into the target_ops.
1383 (add_to_section_table): Add BFD to section table.
1385 * target.c (target_xfer_memory, target_info): Pass target to
1386 xfer_memory and target_info functions.
1389 * gdbcore.h: Move struct section_table.
1390 * target.h: New home of struct section_table.
1392 * solib.c (solib_add): New argument is the target_ops whose
1393 section list is to be added to, if any. Reallocate the
1394 sections in that target to add any that come from shared libs.
1395 (throughout) so_sections renamed to sections.
1396 (solib_xfer_memory): Deleted.
1397 * tm-sunos.h (SOLIB_ADD): Add target argument.
1398 (SOLIB_XFER_MEMORY): Delete.
1400 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1401 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
1402 from target_ops. It's the same on all targets. Add two section
1403 pointers to target_ops.
1405 * stack.c (find_relative_frame): Dump ancient algorithm for
1406 "down", just use handy "next" pointers.
1407 (frame_command): Don't error if there is no stack; let user
1410 * inflow.c (new_tty_prefork, new_tty): New prefork routine
1411 modifies static state in the parent process; new_tty itself
1412 runs in the child and modifies the child's file descriptors
1413 to match the saved static state.
1414 * infrun.c (child_create_inferior): Call new_tty_prefork,
1417 * infptrace.c (child_xfer_memory): Add ignored target arg.
1418 * remote-eb.c (eb_xfer_inferior_memory): ''
1419 * remote-nindy.c (nindy_xfer_inferior_memory): ''
1420 * remote-vx.c (vx_xfer_memory): ''
1421 * remote.c (remote_xfer_memory): ''. Rename from
1422 remote_xfer_inferior_memory.
1424 * main.c (main): Only try to attach "corefile" argument if
1425 it starts with a digit.
1427 * symfile.c (symbol_reloading): New "set/show" variable.
1428 (symbol_file_add): Shorten message about symbol reading.
1429 (add_symbol_file_command): Merge with add_syms_addr_command,
1430 since this should work on all targets now.
1431 (stop_whining): Default to zero, to shut up complaints
1432 about bad symbol tables on many systems.
1433 (free_named_symtabs): Just exit unless symbol_reloading.
1435 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
1436 and add comment explaining shared library screw.
1438 * source.c: #if defined => #ifdef.
1440 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1442 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
1444 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1446 * doc/rdl-apps.texinfo: provide default readline-appendix finder
1447 (doc/Makefile knows how to make one for local config)
1449 * Makefile.in: use doc/Makefile for doc targets
1451 * doc/Makefile: GDB documentation now has its own Makefile
1452 doc/refcard.tex: renamed from "gdbrc.tex"
1453 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
1454 doc/gdbint.texinfo: add markup in "Cleanups" chapter
1457 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1459 * values.c (baseclass_addr): When reading target memory, use the
1460 length of the basetype, not the upper type. We've only malloc'd
1461 enough space for the basetype, leading to errors in free().
1463 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
1464 ends up as a function specially, since we know the actual type of
1465 the pointed-to address. This (somewhat) fixes display of
1466 expressions that include misc_function_vector names. Try `cond 1
1467 !strcmp("a","b")' then `i b'.
1469 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
1470 The child can be proceeded from inside wait_for_inferior in
1471 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
1472 getting skipped in that case.
1474 * expprint.c (print_subexp): Use filtered output, since the
1475 subroutines we call use it, otherwise the output is horribly
1476 mangled, since output of wrappable stuff comes out late.
1478 * Makefile.in: Bump VERSION to 3.98.1
1480 * infrun.c (child_create_process): Use execlp to find the
1481 shell to exec our target program. This requires some fiddling
1482 with `environ' since there is no execlpe().
1484 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1486 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
1487 Minor rearrangement of refcard permits two new make targets--
1488 gdbrc.dvi DVI output for refcard, using CM fonts
1489 gdbrc.ps PostScript refcard, using PS fonts
1491 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1495 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
1496 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
1498 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1500 * doc/gdb.texinfo: last changes for release.
1501 Minor typo and formatting fixes; incorporated most fixes remaining from
1502 filed mail commenting on earlier drafts.
1504 Added warnings: pipes don't work in run command;
1505 conditions are converse of assertions;
1506 step over fn without debug info goes to next fn;
1507 vars may have "wrong" values near fn entrance, exit
1509 Added example from Kingston on printing repeated nonadjacent values
1511 Added explicit mention that in Emacs gdb mode C-c and C-z are like
1512 shell mode for signals
1514 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
1515 doesn't sound so much like its parent "Stopping and Continuing"; also
1516 moved entries on continue to top of section, so they don't get lost.
1518 Improved installation directions in appendix, added manual formatting
1521 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1523 * configure.in: Remove xm.h and tm.h even if we aren't linking
1524 new ones, so "./configure sun4; ./configure none" does the right
1525 thing. Assume that alldeps.mak and depend are already built in
1526 srcdir, and avoid running "make" (particularly "make depend",
1527 which involves "gcc") from inside configure. Build Makefile
1528 directly rather than building Makefile.conf first.
1529 * configure: Regenerate with above changes.
1530 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
1531 to 3.98. Revise gdb.tar.Z procedure to produce a file
1532 called gdb-$(VERSION).tar.Z but which unpacks into a
1533 directory called "gdb". Move non-source files out of
1534 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
1535 (depend): Don't try to do "gcc expread.y".
1536 (expread.o): Update dependencies by hand.
1538 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1541 Fixed a variety of small typos that prevented info from formatting
1542 cleanly; altered too-long heading for GPL Appendix, as discussed
1543 w/RMS; Changed date on cover to July 91.
1545 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1548 (1) Applied some fixes due to comments from Larry Breed (easier ones
1549 through chapsec 5.2)
1550 (2) Eliminated use of @footnote---had my doubts about it anyways, and
1551 it's broken in latest texinfo
1552 (3) Introduced *some* use of [] for optional arguments, where
1553 explanation is not simpler by listing cmd w arg and cmd w/out arg
1554 separately. Still not using @deffn.
1555 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
1556 couple of headings are too long. Need patches to texinfo or revision
1559 * Partial update to README (which still needs work for this
1560 release!): (1) use of configure corrected for new script,
1561 (2) "make gdb.dvi" and "make gdb.info" mentioned.
1563 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
1565 * symtab.c (lookup_symbol): Don't complain right off about
1566 no debug symbols; use the misc function vector first.
1567 (list_symbols): Use misc function vector to find symbols
1568 that don't have debug info, and print them.
1569 (find_pc_symtab): Temporarily avoid fatal() when psymtab
1570 PC range doesn't match symtab PC range, as it does on the
1571 MIPS because our symtab reading isn't perfect.
1573 * dbxread.c (dbx_symfile_read): Make warning about
1574 "no debug symbols" slightly nicer.
1576 * source.c (select_source_symtab): If "main" symbol exists,
1577 but decode_line_spec can't find line info, don't just return
1578 a zero; try other source symtabs or give an error.
1580 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
1581 their low addresses first, then rip through fixing high addrs.
1583 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
1584 <runene@ifi.uio.no>.
1585 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
1587 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1589 * Minor, mostly mechanical, cleanup of doc subdir for clean
1590 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
1591 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
1593 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
1595 Mostly MIPS and general symbol-reading fixups.
1597 * doc/gdbint.texinfo: Add documentation on symbol-reading
1600 * mipsread.c: Remove kludges around #include "ecoff.h".
1601 Remove redefinitions of a_magic, etc, no longer used.
1602 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
1603 Fix global overview comments to match symfile.c protocol.
1604 (mipscoff_new_init): Eliminate cur_hdr if we have one.
1605 (mipscoff_symfile_read): Eliminate unused code. Avoid
1606 sorting all the symtabs, when all we have read here is psymtabs.
1607 The symtabs are sorted as they are created anyway. Tell
1608 condense_misc_bunches whether we're mainline.
1609 (psymtab_to_symtab_1): Pass filename when recursing, to make
1610 stack trace more informative.
1611 (parse_partial_symbols): Assume cur_hdr as argument.
1612 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
1613 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
1614 the TYPE_NAME of char *, since that's done in symfile.c.
1615 (free_numargs, parse_symbol, add_symbol, add_block,
1616 shrink_linetable): Declare these fns void.
1617 (upgrade_type): Convert tree of if's to switch. Clean up
1618 bogus "off == 0" handling with a complaint. Avoid setting
1619 field bitpos and bitsize of array with lower and upper bounds.
1620 Check specified bitsize of elements against their actual type's
1621 bitsize, and complain if different. Complain about unknown
1623 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
1624 (psymtab_to_symtab_1): Print names of subsidiary files that
1625 are being read in. FIXME, we read far too many files. This code
1626 is not the problem, the problem is in parse_fdr where the psymtabs
1628 (cross_ref): Result should indicate that we used one aux entry
1629 normally, or two if we encountered a "next" entry. This used
1630 to leave the caller pointing at the wrong aux entry.
1631 (add_symbol): If overflowed cur_block, reallocate it larger,
1632 chase all pointers to it, and complain(), rather than clobber memory.
1633 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
1634 (new_field): Only allocate one field initially, not two.
1635 Pull ++ out of macro argument. Simplify.
1636 (_initialize_mipsread): Avoid initialization of importd
1637 global_psymbols and static_psymbols.
1639 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
1640 to properly set pst->symtab; avoid searching for it.
1641 (symfile_fns): Improve comments, add a FIXME.
1642 * dbxread.c: Update comments to reflect symfile protocol.
1643 (read_ofile_symtab, end_symtab): Return the symtab.
1644 (psymtab_to_symtab_1): Set pst->symtab.
1646 * coffread.c (coff_symfile_read): tell condense_misc_bunches
1647 whether we're mainline.
1649 * symfile.h (sym_fns): Remove unused sym_discard member.
1650 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
1652 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
1653 the environment variable is not.
1654 * infcmd.c (finish_command): Use filtered printfs.
1655 * cplus-dem.c: Add struct tags to a few unnamed structs.
1656 * valops.c (value_coerce_array): Improve comments.
1657 * valprint.c (type_print_varspec_suffix): Print array size only
1658 if greater than zero.
1659 * m88k-tdep.c: Shift some lines left by one space, that had
1660 apparently been trashed at some point.
1661 * TODO: More things to do, a few got done.
1663 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1665 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
1666 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
1668 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
1669 * expread.y, findvar.c, symmisc.c: Ditto.
1670 * printcmd.c (address_info): Update printed forms of LOC_
1671 symbols. Elim LOC_EXTERNAL.
1672 (print_frame_args): Keep track of param stack offsets before
1673 re-looking up to find the local register param is kept in.
1675 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
1676 Further integration of mipsread into gdb. Eliminate unused
1677 routines, duplicate declarations. Handle static symbols in
1678 psymtabs as well as external symbols. When reading symtabs,
1679 insert symbols into the correct block (global, static, or a local
1681 (read_mips_symtab, parse_partial_symbols): Don't pass useless
1683 (mipscoff_symfile_read): Don't call select_source_symtab.
1684 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
1685 rather than SYMBOL_VALUE.
1686 (parse_external): Comment clobbering of top_stack.
1687 (parse_partial_symbols): Update comments. Allocate and parse
1688 static symbols as well as external symbols. FIXME, enum values
1689 are not handled in this pass, but should be. Inline new_psymbol.
1690 Use SYMBOL_VALUE_ADDRESS.
1691 (psymtab_to_symtab_1): Read symbols into global static block
1692 by default (until enter some function's local block context).
1693 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
1694 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
1696 * source.c (select_source_symtab): Select a source symtab
1697 from either the symtabs or, failing that, the psymtabs.
1698 (list_command): Update error message.
1699 (forward_search_command, reverse_search_command): Use getc, not
1700 fgetc, for speed. FIXME, add comment about buffers that die if
1701 overrun by long line.
1703 * values.c (unpack_field_as_long, modify_field): Avoid shifting
1704 by an entire word, which is not portable, if we have a 32-bit
1705 field. (Code in dbxread.c already turns such bitfields, if
1706 aligned, into ordinary ints, but fixing this will help for other
1707 symbol formats and for future changes.)
1708 * core.c (core_open): Handle ANSI const brain death.
1709 * utils.c (vprintf): Fix varargs typo.
1711 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1713 * findvar.c (find_var_value): Handle &function better.
1714 * TODO: Document work needed on &fn and &array.
1715 * printcmd.c (print_address_symbolic): New arg is the prefix
1716 to print if a name is printed.
1717 (print_address_demangle): Honor "set print address" now.
1718 Use new arg above to improve spacing of output.
1719 * valprint.c (val_print): When printing function pointers,
1720 print symbolic form too.
1721 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
1723 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1725 * core.c (memory_error): Reword error msg to mislead less.
1727 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
1729 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
1730 parse_partial_symbols): Use newer BFD internals (external_filehdr
1731 and external_aouthdr), byte-swap the fields that we care about
1732 before using them, and make the file header data local to
1733 read_the_mips_symtab rather than global.
1735 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
1737 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
1738 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
1740 * main.c (command_line_input): Flush stdout and stderr
1741 before every call to readline. This reportedly fixes a bug
1742 that comes up in Sys V running emacs-gdb and/or xxgdb,
1743 when stdin/out are pipes or sockets.
1745 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1747 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
1748 Avoid declaring Makefile dependencies, because GNU Make stupidly
1749 tries to update it if we do.
1751 * coffread.c: Revise for minor changes to bfd internal coff
1754 * configure: If -template= is given a relative path, make it
1755 absolute before recurring in subdirectories.
1757 * configure, configure.in, Makefile.in: Install "configure" script
1758 as replacement for config.gdb.
1759 * config.gdb, Makefile.dist, Makefile.sdir: Remove
1760 * README: Update for configure, mostly. FIXME.
1762 * Add dec3100 as equivalent to littlemips. Indicate in all host &
1763 target config files that they are for the host. When the lines
1764 get copied into the Makefile, this makes it more obvious what's
1767 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1769 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
1770 tabs, which end up in the disassembler output inadvertently.
1772 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1774 Make it compile cleanly in an ANSI GCC2 environment.
1776 * blockframe.c: <stdio.h>
1777 * cplus-dem.c: free takes a void *, ifdef __STDC__
1778 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
1780 * defs.h (alloca): Avoid doing anything if alloca already def'd.
1781 * stddef.h, stdlib.h: Remove these files.
1782 * symtab.c: Avoid declaring qsort, close.
1783 * symfile.c: Avoid declaring close.
1784 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
1785 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
1787 Assorted other changes.
1788 * dbxread.c: include "libaout.h", not "liba.out.h".
1789 * printcmd.c (print_frame_args): Set recurse properly for
1790 indentation of struct and array parameters.
1791 * valops.c (value_cast): Allow cast to void.
1792 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
1793 single_step() in a target-independent fashion.
1794 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
1795 set up to be ready to continue. This makes us target independent.
1796 * infptrace.c (child_resume): Remove call to single_step; now
1797 can single step a SPARC target of any kind.
1799 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1801 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
1802 docn into separate sections---basically chapters, plus two loose
1803 pieces that can be configured to go in different places. This
1804 allows GNU m4 to preprocess the manual without coredumping.
1806 * Makefile.dist: tell TeX where to find texinfo.
1808 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1810 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
1811 the new target "rdl-apps.texinfo" which captures the Makefile
1812 variable that records where to find the Readline libraries.
1814 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
1816 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
1817 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
1818 * defs.h (const, volatile): Only define if not already defined.
1819 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
1821 * README: Update for release 3.95.
1822 * config.gdb: Don't create readline dir in subdir builds.
1823 * main.c: Include with "..." form for non-system include files,
1824 so "gcc -MM" for "make depend" works.
1825 Include readline files with "...h" rather than <readline/...h>.
1826 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
1828 * coffread.c: Undo minor damage done by Rich Pixley. Use
1829 different internal and external representations of COFF
1830 data structures. Use new BFD routines for swapping them in and
1832 * symfile.c (free_named_symtabs): Avoid freeing file names that
1833 are null or empty. Old i960 tools seem to produce files that
1834 claim to have empty names, causing each successive file read
1835 to blow away the previous one.
1836 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
1837 Move deferred_stores to top of file, but don't separate its
1838 #define's from its variable. Add commentary.
1839 * Makefile.dist: Fix Rich damage; undo "configure" changes in
1840 favor of keeping the (working) config.gdb. Move readline
1843 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
1845 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
1847 * infptrace.c (fetch_registers): no result, since now void.
1848 * tconfig/news: target depends on m68k-tdep too.
1850 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1852 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
1855 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
1856 applied various small fixes due to or inspired by RMS comments
1858 * doc/gdb.texinfo: finished using all RMS comments, save those for
1859 appendices on readline and cmd history (which are in other source
1862 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1864 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
1865 chapter 9; (2) documented 'break' command's menu mode for
1866 overloaded names, in response to hgs problem report C++ p-31
1868 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1870 * doc/gdb.texinfo: (1) better introductory example; (2) more
1871 consistent use of @code, @samp, @file, @kbd throughout; small
1872 cleanups to first three nodes; (3) new "Contributors" node;
1873 (4) Appendix, Renamed Commands; (5) divert specialized startup
1874 instructions to "Targets" chapter for generic manuals, while
1875 leaving them up front for manuals specific to specialized
1876 environments; (6) apply fixes from RMS comments through chapter 4.
1878 * pretex.m4: modify explanatory text slightly (and redefine
1879 "regexp") to keep GNU m4 from complaining. (It still crashes
1880 later, but one step at a time...)
1882 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
1884 * readline/readline.c (update_line): Avoid dereferencing a pointer
1885 before comparing it to its bounds. Saber caught this.
1886 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
1887 and only set PC if tgetstr returned non-null. Saber caught this.
1889 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1891 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
1892 stuff for config manual) here where it counts; updated
1893 to use new subdir structure (gdb/doc/).
1895 * Makefile: generated from above via
1899 * gdbint.texinfo: added instructions on generating gdb.info* files
1900 locally for release. These are ordinary info
1901 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
1902 Makefile)---but due to use of texinfo 2, can't count on makeinfo
1903 to generate these, so we distribute them already formatted.
1905 * gdb.texinfo: included full Info node and menu crud (as generated
1906 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
1908 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
1909 put in comments-for-future gdb.info target (one day makeinfo will
1912 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1914 * gdb.texinfo: Updated to include new or old undocumented
1915 commands, at least the following (perhaps some others I forgot to
1916 record): info f, info float, info path, info program, info s, info
1917 set, info source, info terminal, info types, info user, set/show
1919 Also covered all recent GDB command renames for v4.
1921 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1923 * mipsread.c: Rather than keeping count of how many symtabs
1924 and psymtabs we have, for sorting purposes, count them when
1925 we need to sort. This fixes bug in rereading of symbol tables.
1927 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1929 * infcmd.c: renamed "info path" to "show paths"
1930 * gdbrc.tex: documented above.
1932 Wed May 8 04:51:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1934 * remote.c: Fix comments.
1935 * utils.c (error): Force out any pending wrap output.
1937 Sat May 4 11:11:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1939 * Makefile.dist: Roll VERSION to 3.95.
1940 Fix up "saber_gdb" to work again.
1941 * saber.suppress: Update.
1943 * coffread.c, exec.c, infptrace.c, inftarg.c, remote.c, solib.c,
1944 symtab.h, target.c, target.h: Lint.
1945 * core.c: setup and select frame after reading shared libs,
1946 else reading shared libs will clobber them. Lint.
1947 * utils.c (error): Force out any buffered wrap text.
1949 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1951 * remote.c: Remove decls of memory_insert_breakpoint
1952 and memory_remove_breakpoint, no longer used. (Suggestion of
1955 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
1956 to make it easier to interface to "configure"'d libraries.
1958 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
1960 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
1961 aliases for set/show print.
1963 Thu May 2 11:22:02 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
1965 * coffread.c (coff_sym_fns) [TDESC]: Make the type be m88kbcs.
1967 * m88k-tdep.c (IEEE_isNAN): New function.
1969 * infrun.c, m88k-tdep.c, m88k-xdep.c: Change
1970 initialize_{tdesc,dcontext} to init_{tdesc,dcontext}.
1972 * infrun.c [TDESC]: Add a bunch of crud.
1974 * xm-88k.h [__GNUC__]: Don't define memset.
1976 * m88k-xdep.c: #if 0 out push_breakpoint.
1978 * tm-88k.h: Define GET_SAVED_REGISTER.
1980 * tm-88k.h: Define DGUX.
1982 * m88k-opcode.h (UEXT, SEXT, MAKE): Put parentheses around arguments.
1984 * m88k-pinsn.c (sprint_address): Declare at top of file.
1986 * m88k-xdep.c: #if 0 out core_file_command.

2459 * values.c: Rename value_history_info to show_values.
2460 (_initialize_values): Rename "info values" to "show values".
2462 Sun Apr 14 23:08:34 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
2464 * inftarg.c (child_open), remote-vx{,.68}.c (vx_proc_open):
2465 New function to give correct error message.
2467 Thu Apr 11 17:19:41 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
2469 * target.h: Add to_doc and target_preopen.
2470 target.c: Add target_preopen and target_command.
2472 (add_target): Call add_cmd and mess with targetlist->doc.
2473 core.c, exec.c, remote-eb.c, remote-nindy.c, remote-vx.c,
2474 remote-vx.68.c, inftarg.c, remote.c: Add doc field to target struct.
2475 Call target_preopen from open routine.
2477 * main.c: Rename editing_info to show_commands.
2478 (_initialize_main): Rename "info editing" to "show commands".
2480 * source.c: Rename directories_info to show_directories.
2481 (_initialize_values): Rename "info directories" to "show directories".
2483 * values.c: Rename convenience_info to show_convenience.
2484 (_initialize_values): Rename "info convenience" to "show convenience".
2486 * copying.awk (_initialize_copying): Rename "info copying" to
2487 "show copying" and "info warranty" to "show warranty".
2488 Rename {copying,warranty}_info to show_{copying,warranty}.
2490 * symfile.c: Rename add_syms_command to add_symbol_file_command.
2491 (_initialize_symfile, add_syms_addr_command):
2492 Rename add-syms to add-symbol-file.
2494 Thu Apr 18 18:08:30 1991 John Gilmore (gnu at cygint.cygnus.com)
2496 * symfile.h (free_named_symtabs): Rename from free_named_symtab.
2497 * symfile.c (clear_symtab_users_once, cashier_psymtab,
2498 free_named_symtabs): Move these routines from symmisc.c.
2499 * symmisc.c (same): same.
2500 (free_symtab): Make non-static.
2501 * symtab.h (free_symtab): Declare as exported void fn now.
2502 * dbxread.c (end_symtab, end_psymtab): Change comments.
2503 (initialize_dbxread): Call dbx_new_init() in case the first
2504 command is add-symbols.
2505 * target.c (dummy_target): Permit add_syms_addr_command.
2507 Sat Apr 13 14:46:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2509 Permit symbols to be superseded when new symbol files have
2510 been read in, particularly for VxWorks.
2512 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
2513 to the main file, as well as to include files. Also, put global
2514 functions into the global psymtab, to make "i fun" work.
2515 (end_psymtab): Free named symtabs and psymtabs for a file, once a
2516 new psymtab for it has been read.
2517 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
2518 a file, once a new symtab has been read for it.
2519 * mipsread.c: FIXME. We need to do the same for MIPS, but it
2520 looks harder to determine the top-level block before it's been
2521 queued to the psymtab list.
2523 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
2524 If we have wiped out any old symbol tables, clean up at end of
2526 (symbol_file_command): Don't reference symfile_fns if it's zero.
2528 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
2529 defines for the blocks of a blockvector that contain global and
2530 file-static symbols and the first of the smaller scope contours.
2531 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
2532 decode_line_1, make_symbol_completion_list): Use the above.
2533 * coffread.c (end_symtab, patch_opaque_types): Ditto.
2534 * dbxread.c (end_symtab): Ditto.
2535 * expread.y (block): Ditto.
2536 * mipsread.c (throughout): Ditto.
2537 * symmisc.c (free_named_symtabs): Ditto.
2539 * symtab.c (list_symbols): Process the first symbol of the
2540 static psymbols list.
2541 (types_info): Restore this function from its untimely #if 0.
2542 It's not perfect, but it is better than nothing.
2543 (_initialize_symtab): Restore "info types".
2545 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2547 * m68k-stub.c: Remote stub for 680x0's, created from
2548 rem-m68k.shar (which is removed).
2549 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
2550 Remove RCS log stuff now that we use CVS and it blows our diffs.
2552 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2554 * symmisc.c (free_named_symtab): Make it work, in its current
2555 kludgy fashion. Change result to indicate if we blew away bkpts.
2556 * dbxread.c (end_symtab): Accumulate result from
2557 free_named_symtab and print warning if we blew user's state.
2558 * symfile.h: free_named_symtab now returns an int.
2560 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
2562 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
2563 is the first symbol read, even if not mainline.
2564 (dbx_psymtab_to_symtab): symfile might be zero, cope.
2565 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
2566 (set_section_command): New command ("section xxx yyy" -- should
2567 be renamed to "set section xxx yyy" FIXME) which sets the
2568 base address of a section of the exec file, overriding the
2569 virtual address that BFD reports.
2571 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2573 * exec.c: Add add_syms_addr_command to exec_ops, so you can
2574 load symbols at any address while examining an exec file.
2576 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
2578 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
2579 for printing the float info is host-dependent, not
2580 target-dependent. FIXME.
2581 * i386-pinsn.c: Move #includes to top, remove useless ones.
2582 * i386-tdep.c: Don't bother including <.../reg.h> since we
2583 don't use it (and it doesn't exist on host systems).
2585 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
2586 Convert negative numbers properly.
2587 (ieee_test): Make numbers really random; fix format arg.
2589 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
2590 * core.c (core_detach): Unpush core_ops, which might not be on
2591 top. We used to just pop the top, which broke things. Don't
2592 need dont_repeat() any more.
2593 (core_file_command): Psst! Don't repeat it.
2594 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
2595 * expprint.c (print_subexp): Avoid switch fallthru on
2596 BINOP_ASSIGN_MODIFY, so we can print += and such.
2597 * frame.h: Fix typo.
2598 * inflow.c (kill_command): After killing inferior, print our
2599 current frame in the core file, if we have one.
2600 (generic_mourn_inferior): When inferior dies, either select
2601 the current frame (in the new target, e.g. core file), or
2602 set both the current and selected frames to NULL.
2604 Changes from Peter Schauer.
2606 * infptrace.c: Avoid <sys/ptrace.h> on USG.
2608 * Make all file names fit in 14 characters (sigh and damn!):
2609 mv hp300hpux-xdep.c hp300ux-xdep.c
2610 mv symmetry-xdep.c symm-xdep.c
2611 mv symmetry-tdep.c symm-tdep.c
2612 mv convex-opcode.h convx-opcode.h
2613 mv tm-vxworks960.h tm-vx960.h
2614 mv tm-vxworks68.h tm-vx68.h
2615 mv Makefile.srcdir Makefile.sdir
2616 mv gdb-int.texinfo gdbint.texinfo
2617 mv remote-sa.m68k.shar rem-m68k.shar
2618 mv remote-multi.shar rem-multi.shar
2619 * Makefile.dist, README, config.gdb, convex-pinsn.c,
2620 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
2621 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
2624 * command.c (user_info_1, user_info): New command for listing
2625 the user-defined commands.
2627 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
2629 * dbxread.c (really_free_pendings): Clear file_symbols
2630 and global_symbols after freeing them; otherwise, running
2631 this function twice (if it appears twice on the cleanup
2632 chain), we try to free things twice.
2634 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
2635 based on text_addr (the address of text in core), not on addr (the
2636 offset between text in the .o file and in core). This change
2637 is from Peter Schauer.
2639 * main.c: Define ALL_CLEANUPS as a cast of zero.
2640 (return_to_top_level): Use it.
2641 (main): Do all cleanups after each command run as part
2642 of the gdb startup sequence. Also do all cleanups before
2643 entering the command loop, and every time we exit the command
2644 loop and reenter. Before, the cleanups from the startup sequence
2645 were being left undone until the first error!
2646 (command_loop): Rename do_nothing cleanup to command_loop_marker
2647 so we can see it easily when examining the cleanup chain.
2648 (init_signals): Add another do_nothing for signal handling.
2649 (quit_command): Only try to kill target if it has execution.
2650 Problems in the target stack got us into a state where
2651 inferior_pid was nonzero but none of the targets had execution.
2652 In this state you couldn't exit gdb.
2654 * dbxread.c: Two changes from Peter Schauer.
2655 (echo_command): Fflush output after an echo command.
2656 (show_history): Pass all args to cmd_show_list.
2658 * utils.c (init_malloc): Call mtrace to turn on tracing
2659 if the environment variable MALLOC_TRACE is set to a file name.
2660 * mtrace.c: Add source file which provides a log of every malloc,
2661 free, and realloc to a trace file.
2662 * mtrace.awk: Add source file which analyzes the trace file.
2663 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
2664 (VERSION): Roll to 3.94.3.
2666 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
2667 (check_duplicates): Don't bother with watchpoints.
2668 (set_raw_breakpoint): Comment about danger of this routine.
2669 (watch_command): Parse and eval all args before calling
2672 * solib.c (find_solib): Avoid error in referencing memory to
2673 see if any more shared libraries have been added. This is
2674 particularly useful if the target has terminated. Bug reported
2677 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
2678 in bringing up 3.94.2 on the Sun-3.
2680 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
2681 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
2682 expression (in scope) before reenabling watchpoint.
2683 * signame.c (init_sigs): Add missing declaration of i, fix
2684 sys_siglist declaration.
2685 * source.c (list_command): Fixed range computation to use
2687 * stack.c (backtrace_command): Do not allow command if target has
2688 no stack, print informative error message.
2689 * target.c (target_command): Do not write into command line
2690 because this fails if the target command is used in a user defined
2691 command. [This change was enhanced by gnu to support any-
2692 unique-prefix matching on target names.]
2693 * valops.c (value_struct_elt): Avoid infinite loop on an
2694 erroneous attempt to print the member of function (try p main.p).
2696 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
2698 * expread.y (name_no_typename): Avoid reduce/reduce errors
2699 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
2700 Since the GDB parser really doesn't use name_no_typename in a
2701 name-only context, the parser can't tell the diff between
2702 names and numbers here. Avoid allowing a name_no_typename
2703 to be a NAME_OR_*INT to resolve the conflict.
2705 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2707 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
2709 * valprint.c (val_print_fields): bitfield printing didn't handle
2710 byte order. Indirect through a few more fns to cope.
2712 * values.c (modify_field): also cope with byte order.
2714 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2716 Cleanup for release 3.94.2:
2718 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
2719 include files. Roll version to 3.94.2.
2721 * coffread.c (init_stringtab): Read length into unsigned char
2722 array before swapping; don't assume 32-bit longs.
2724 * target.c (target_info): Don't bother with get_sym_file, just use
2725 the symfile global variable.
2726 * symtab.h, symfile.c (get_sym_file): Delete it.
2728 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
2729 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
2730 (read_type): Replace one more error() with complain().
2732 * mipsread.c (parse_partial_symbols): Replace printf with complain.
2734 * i960-tdep.c: Fix copyright attribution.
2736 * config.gdb: Quote all backquotes in doublequotes. You can
2737 quote me on that. BSD 4.4 shell found this one.
2739 * infptrace.c (throughout): The third argument to ptrace is an
2742 * infrun.c (wait_for_inferior): When program has terminated, we
2743 have to call target_terminal_ours before we pop that target off
2744 the stack (e.g. before a call to target_kill or
2745 target_mourn_inferior). This fixes problem where a program
2746 terminates, then GDB stops for (tty output) and you have to type
2747 "fg" to the shell to resume it. FIXME: This code for what to
2748 do after termination really should be in normal_stop instead.
2750 * gdbcore.h (read_memory_check): Change declaration; it changed
2753 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
2754 4.4 prereleases, this avoids a bug in their sgtty compatability
2756 * remote.c: Use terminal.h rather than hand-rolling the same.
2758 * signame.c, signame.h (psignal): Arg is unsigned, not int.
2759 * utils.c (strsave, strstr): Fix arg types.
2760 * valprint.c (val_print): lint
2762 MIPS symbol table support from Per Bothner:
2764 * symfile.c (symtab_fns): Remove initializer table that needs to
2765 be hacked for each new symbol file format supported.
2766 (add_symtab_fns): New function, chains symbol table
2767 handlers into the global list.
2768 (symfile_init): Search this list.
2769 * symfile.h: Add next pointer, declare add_symtab_fns.
2770 * coffread.c (_initialize_coffread): Call add_symtab_fns.
2771 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
2773 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
2774 symbol *). Thus, we no longer need the hack to trash
2775 pst->filename. Good, since that hack confused code in symfile.c!
2777 (reorder_symtabs, destroy_all_symtabs): Removed static
2778 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
2779 Instead, the latter now uses a temporary array (stack-allocated
2780 from an obstack, and then freed).
2782 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
2783 haven't been set in the outermost stBlock of a procedure. This was
2784 a problem with f77 binaries on Ultrix 4.?.
2786 (new_symtab, new_symbol, new_type): Continue changing code to use
2787 obstacks more and otherwise conform to dbxread internal style.
2788 Made the free_code of symtabs be free_linetable (as in dbxread)
2789 instead of free_contents. This implies memory leaks when reading
2790 a new symbol table, until the conversion is finished. Did change
2791 (struct symbol) and (struct type) to be allocated on the
2792 symbol_obstack. Blocks and blockvectors are among the things
2795 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
2796 tested much, but it solved one problem (reported by Meissner), and
2797 cleans up some other things. The problem happened when an
2798 included file contains actual code (functions) and not just
2799 definitions. The mips coff is a little inconvenient there, since
2800 it may cause a procedure to be mapped to the wrong psymtab.
2802 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
2803 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
2804 this will need work for the new core paradigm.
2806 Opcode patches from the net:
2808 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
2809 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
2810 missing altogether - they are added here. From Bruce Bauman.
2811 * mips-opcode.h: The low mask for C0 instructions was too small.
2812 From Garrett Lau. I modified the fix to check the entire 32-bit
2815 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
2818 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2820 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
2822 * dbxread.c (read_type): Pointer subtraction (value_sub in
2823 valarith.c) sometimes failed because the types of the
2824 pointers being subtracted were not identical.
2825 These differed because dbxread.c was allocating pointer types
2826 using dbx_alloc_type+smash_to_pointer_type instead of
2827 lookup_pointer_type. I failed to find a justification for the
2828 former, so I changed it to use the latter. Similarly, I
2829 replaced smash_to_function_type by lookup_function_type,
2830 and smash_to_reference_type by lookup_reference_type.
2832 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
2833 _initialize_mipsread): corresponding changes.
2835 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
2837 * source.c (mod_path): Do tilde_expand on each component of the path,
2838 rather than on the (list of) paths as a whole.
2839 (print_source_lines): Set first_line_listed in addition to
2840 current_source_symtab and current_source_line. If the source was
2841 not findable, after a "dir" command to fix the problem,
2842 a "list" would get the wrong lines.
2844 While I was there... (gnu):
2846 * dbxread.c (read_type): Change error to complaint.
2848 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2850 First attempt at detailed understanding of symbol table memory alloc.
2852 * dbxread.c (dbx_symfile_read): Free our string table if we
2853 aren't the mainline. Free the "info" struct since we're done with
2855 (init_psymbol_list): Free any previously allocated psymbol lists.
2856 (): FIXME: Should realloc-down the psymbol lists when done reading
2857 the main symbol file?
2859 * symmisc.c (free_symtab): Free fullname field too.
2861 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
2862 (REGISTER_ADDR): Make result type unsigned int.
2864 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
2865 define REGEX must also define REGEX1 (its dependency).
2867 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
2869 * tconfig/i960: No longer works, points you at vxworks960 or
2872 * xgdb.c, XGDB-README: Remove file. Users can get the much
2874 * Makefile.dist: Remove all trace of xgdb.
2876 * breakpoint.c (breakpoint_1): Pass demangle arg to
2877 print_address_symbolic.
2878 (clear_breakpoints): Remove unused function.
2879 (breakpoint_re_set_one): Guts of breakpoint_re_set.
2880 (breakpoint_re_set): Use catch_errors to do them all anyway.
2882 * gdb-int.texinfo (Host versus Target): Add section on what is
2883 a "host" feature versus what is a "target" feature.
2885 * infcmd.c (path_command, path_info): Handle the PATH variable
2886 (object search path) as conveniently as the source search path.
2887 * environ.c (set_in_environ): Set some vars in GDB's environment,
2888 in addition to the child's. PATH, G960BASE, G960BIN for starters.
2889 * source.c (mod_path): New function, from guts of
2890 directory_command, modifies a path. Used by path_command.
2891 (directory_command): Call it.
2892 * defs.h (strsave): Declare.
2894 * utils.c (sevenbit_strings): Add new printing option.
2895 (printchar): Use it.
2896 (strsave): Provide this handy helper routine.
2897 (set_width_command): Rename set_screen_width_command.
2898 (_initialize_utils): "set screen-width" => "set width";
2899 "set screen-height" => "set height"; add sevenbit-strings.
2901 * infcmd.c (do_registers_info): Print floating point registers
2902 in raw hex as well as float format, regardless of whether it is
2903 a "virtual" convertible register.
2904 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
2905 regs as a double, just in case it's being used that way.
2906 * values.c (unpack_long): Comment on array/function coercion.
2907 (unpack_double): Argument is in target byte order now. For
2908 integer arguments, just call unpack_long and float the result.
2909 * m68k-tdep.c: include defs.h for "const" handling.
2910 * remote-nindy.c: Use ieee-float stuff.
2911 (nindy_fetch_registers): Unpack double regs to host double, then
2913 (nindy_store_registers): Pack extendeds to host double, flip
2914 around by misusing unpack_double, send as target double.
2916 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
2917 zero, as when stopped at the first instruction of a process.
2919 * blockframe.c: Fix filename in comment (param.h => tm.h).
2920 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
2921 * tm-68k.h: Fix typos.
2923 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
2925 Changes from a bringup on the DEC Vax under Ultrix 4.0.
2927 * coredep.c (fetch_core_registers): Pass end-address of register
2928 section to register_addr as expected. Don't call supply_register
2929 if we'd just pass it garbage.
2931 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
2933 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
2935 * target.c (push_target, target_info): Cast enums to int for < or
2938 * stack.c (print_frame_info): Identify source file & line
2939 even if we can't print it.
2941 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
2943 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
2945 Clean up IEEE floating point support.
2947 * ieee-float.h: New file.
2948 * ieee-float.c: Write real routines to convert between host
2949 doubles and various target IEEE extendeds.
2950 * m68k-xdep.c: Eliminate assembler code for extended floats.
2951 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
2952 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
2953 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
2954 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
2955 double_to_ieee_extended.
2956 * i960-tdep.c: Define ext_format_i960.
2957 * m68k-tdep.c: Define ext_format_68881.
2958 * sparc-tdep.c: Define ext_format_sparc, though unused.
2959 * Makefile.dist (HFILES): Add ieee-float.h.
2960 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
2963 Obsolete the "coffstrip" program in favor of using BFD's strip.
2965 * nindy-share/coffstrip.c: Remove file.
2966 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
2967 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
2968 * tconfig/nindy960: Remove reference to coffstrip.o.
2970 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
2972 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
2974 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
2975 * dbxread.c: Remove static symfile_bfd.
2976 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
2978 * inftarg.c (child_detach): Pop the child_ops vector if the
2979 detach is successful.
2980 * remote-nindy.c (nindy_create_inferior): Don't push a new
2981 nindy_ops since nindy uses the same one for execution and memory
2983 * core.c (core_ops): Use child_attach and child_create_inferior
2984 rather than default attach and create_inferior functions.
2986 Handle floating point registers in core files.
2988 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
2989 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
2990 This version untested since BFD doesn't yet support sun3 core
2992 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
2993 conventions. Fix comments and style. This version has not
2994 been compiled yet, since we have no HP inhouse.
2995 * core.c (get_core_registers): Look for two sections, ".reg"
2996 and ".reg2", and pass both to fetch_core_registers sequentially.
2998 Revise directory path yet again.
3000 * source.c (forget_cached_source_info): Not static any more.
3001 (init_source_path): New default source path is "$cdir:$cwd".
3002 (dir_command): Handle variable arguments ($cdir, $cwd).
3003 (source_info): Print "Compilation directory" rather than
3004 "Originally compiled in" to remind people of $cdir.
3005 (openp): If the path contains $cwd, use current directory.
3006 (open_source_file): If compilation directory is known, replace
3007 first $cdir in path with the compilation directory.
3008 (print_source_lines): Even if we can't print the lines, set the
3009 current symtab and line for future commands like "info source" or
3010 "breakpoint". Also, error message now contains the file name,
3011 line number, and file access error message.
3012 (_initialize_source): Fix help text to describe changes.
3013 * main.c (cd_command): Forget cached source info when we chdir.
3014 * utils.c (strstr): Add simple implementation.
3016 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
3018 * coffread.c (read_one_sym, init_linetable, init_stringtab):
3019 Byte-swap COFF symbol tables if necessary when reading them in.
3020 Use complain() to replace error message in one spot. Needs
3021 corresponding change in bfd/coff-code.h to make some symbol
3022 swapping routines non-static.
3024 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3026 Merge changes from Eirik Fuller, for UTek.
3028 * defs.h (errno): Add declaration.
3029 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
3030 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
3031 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
3032 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
3033 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
3034 declarations of errno.
3036 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
3038 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
3039 <rpc/rpc.h> and <rpc/types.h>.
3041 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
3043 * i960-tdep.c (examine_prologue): Add new argument limit,
3044 which stops the scan at the end of the prologue, or at the PC.
3045 This fixes a problem where it walks down into the code for the
3046 user's statements if that code looks like function prologues.
3047 Mark Fox and I have been bouncing this code back and forth, making
3048 small changes to it. Callers changed to match.
3050 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
3052 Cleanup for gdb-3.94 release final:
3054 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
3055 the .c files from vx-share and nindy-share, from the various
3056 macros, since they are not found via ALLDEPFILES.
3057 (SFILES): Add tm-i960.h.
3058 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
3059 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
3061 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
3062 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
3064 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
3066 * am29k-tdep.c: Add contribution line.
3067 (examine_prologue): Cache information about function prologues in
3068 the misc-function-vector to avoid lots of references over the
3069 serial line while examining instructions.
3071 * core.c (core_close): New function made from cleanup_core.
3073 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
3074 remote-vx.c, remote.c, target.c, target.h,
3075 Update target_ops vector to add attach, close, and load entries.
3076 Use add_syms_addr_command, not add_file_addr_command, for
3077 add_file. Break out close routine from existing code.
3079 * dbxread.c (really_free_pendings): Don't free pending_blocks;
3080 they are in an obstack.
3081 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
3083 (define_symbol): Add symbol type parameter; change callers;
3084 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
3085 it to influence the symbol class on the i960.
3086 (define_symbol): Swap LOC_CONST's into target byte order.
3088 * exec.c (exec_close): New function.
3089 (exec_file_command): Call it.
3091 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
3092 Fix byte order of frame pointer.
3093 (read_var_value): Result of 0 if var's value can't be found,
3094 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
3095 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
3096 (locate_var_value): Use read_var_value and use its lazy address
3097 as the location of the var's value. Lint.
3099 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
3102 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
3103 obsolete Intel versions in favor of vxgdb versions.
3104 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
3105 code dealing with byte order of values, which Intel did in host byte
3106 order rather than gdb-4's target byte order.
3107 (i960_frame_chain_valid): Move to nindy-tdep.c.
3108 (examine_prologue, skip_prologue, frame_find_saved_regs,
3109 frame_args_address, leafproc_return, saved_pc_after_call,
3110 pop_frame): Add vxgdb versions from Mark Fox.
3111 (examine_prologue, frame_struct_result_address): Add code
3112 to deal with the saved value of G13 (struct return address
3114 (frame_args_address): Modify Mark's version to prefer the
3115 saved value over the current value in the topmost frame.
3116 Cache result in the frame info to avoid performance hair in
3118 (print_fault): Add gdb960 code for printing faults.
3119 (_initialize_i960): Actually call check_host.
3121 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
3122 add stub routines. FIXME, these currently just return zero!
3124 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
3125 (attach_command): Call target_attach, not target_open, now.
3127 * infrun.c (normal_stop): Make global, not static, for vx_attach.
3128 (child_attach): Rename from child_open.
3129 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
3130 don't confuse it with a zero step_resume_break_address.
3132 * inftarg.c (child_detach): Eliminate inferior_pid test.
3133 (child_files_info): Clean up message a bit.
3134 (child_ops): Use child_attach, not child_open, to attach.
3136 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
3137 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
3138 findvar.c to here, since it depends on the contents of the
3139 shadow_contents of breakpoints, but keep if #if 0 since it is
3142 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
3145 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
3146 (ptype_command, display_command): Eliminate have_inferior_p and
3147 have_core_file_p in favor of target_has_stack or
3148 target_has_execution.
3149 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
3150 code for actually finding the values of arguments, though we still
3151 keep track of the maximum stack offset for use in printing unnamed
3152 arguments. Handle missing FRAME_ARGS_ADDRESS.
3154 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
3155 (struct nindy_regs): Define registers passed to/from nindy.
3156 (nindy_fetch_registers, nindy_store-registers): Translate between
3157 nindy and GDB formats for the registers.
3158 (dcache_init): Statically allocate the cache, since it was being
3159 allocated by a malloc that was never freed anyway.
3160 (nindy_create_inferior): Error, not core dump, if no exec file.
3161 (nindy_before_main_loop): Use target_load, not target_add_file.
3163 * remote-vx.c (net_load): Specify large timeout for load
3164 requests. Allow user to break out with INTERRUPT.
3165 (net_break): Remove useless code, clean up. Change callers.
3166 (parse-args, skip_white_space, find_white_space): Clean up arg
3167 parsing to cope with quoted strings.
3168 (net_wait, net_quit): Never call error, just return status.
3169 (vx_read_register, vx_write_register): Cleanup status checking.
3170 #ifdef the code based on which CPU we are using (960 or 68k),
3171 FIXME, this should be completely general but it isn't yet.
3172 (vx_xfer_memory, vx_resume): Cleanup status checking.
3173 (vx_run_files_info): Improve message.
3174 (vx_load_command): Renamed from vx_add_file_command. Allow load
3176 (net_ptrace): Remove unused routine.
3177 (vx_wait): Adopt code from vxgdb960 to cope with broken
3178 connections to target machine and prompt to disconnect. Remove
3179 debug printouts. Map some EVENT_'s to SIGnals.
3180 (add_symbol_stub, vx_open): Print names of object files we found,
3181 and "ok" if we read their symbols OK. Clarify output in general.
3182 (vx_attach, vx_detach, vx_kill): Add these commands.
3183 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
3184 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
3185 "info files" output, and create_inferior, since we already have
3188 * stack.c (frame_info): Replace Frame_unknown with 0.
3189 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
3190 (return_command): Pop until the PC matches as well as the FP,
3191 so it works even if the FP is shared with another function,
3192 as in "frameless" or "leaf" procedures.
3194 * symfile.c (load_command): renamed from add_file_target_command.
3195 (add_syms_addr_command): renamed from add_file_addr_command.
3196 (add_syms_command): Stub to call target_add_syms.
3197 (_initialize_symfile): Change command names and descriptions,
3198 add-file => add-syms, and load from alias to its own command.
3200 * target.c (kill_or_be_killed, maybe_kill_then_attach,
3201 maybe_kill_then_create_inferior): Default for attempts to start
3202 a process, if one is already running, is to ask about killing
3203 it and retry if yes.
3204 (upstack_create_inferior): #if-0 it, strata obsolete it.
3205 (push_target, unpush_target, pop_target): to_close() a target
3206 before unstacking it.
3207 (target_info): Renamed from target_files_info.
3208 (_initialize_targets): Rename "i files" as "i target", accessible
3211 * target.h: Improve comments about the target_ vectored routines.
3213 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
3214 Convert commenting style to standard GNU style.
3215 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
3216 (SKIP_PROLOGUE): No longer a no-op.
3217 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
3218 (*_REGNUM): Sort register numbers.
3219 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
3220 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
3221 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
3222 are now 10 byte extendeds, not 8 byte doubles.
3223 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
3224 for nindy versus vxworks targets. FIXME, this should possibly go
3225 in the target vector.
3226 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
3227 frame_saved_regs and arg pointer with each frame.
3228 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
3229 (FRAME_ARGS_ADDRESS): Use cached result.
3230 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
3231 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
3232 (PRINT_RAMDON_SIGNAL): Call print_fault.
3233 (POP_FRAME): Now works.
3235 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
3236 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
3237 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
3238 (ADDITIONAL_OPTION_HANDLER): use target_load, not
3241 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
3242 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
3244 * valarith.c (value_subscripted_rvalue): Avoid handling
3245 floats and doubles specially; it gave alignment errors. Lint.
3247 * valops.c (value_of_variable, value_of_this): Error if unknown
3250 * valprint.c (print_floating): Bcopy rather than pointer-deref,
3251 to avoid alignment problems.
3252 (value_print): Handle unknown value address.
3253 (cplus_val_print): Two args are ignored; remove them. Change caller.
3254 (val_print): Use unpack_long rather than pointer-deref.
3257 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
3258 to avoid alignment problems.
3259 (value_being_returned): Error if return value unknown.
3260 (set_return_value): Add bogosity warning, FIXME. *
3262 * TODO: A woman's work is never done.
3264 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
3265 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
3266 Add ieee-float.o to OBS.
3267 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
3268 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
3269 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
3271 Changes to generalize the VxWorks RPC protocol slightly, to handle
3272 i960 as well as 68000.
3274 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
3275 * vx-share/reg.h: Produce i960 regs #ifdef I80960
3276 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
3277 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
3278 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
3279 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
3280 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
3281 so they will move in target byte order rather than network
3282 byte order (happens to be the same).
3284 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
3286 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
3288 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
3291 Add contribution lines to various files, showing where they
3294 * breakpoint.c (break_insn, check_break_insn_size,
3295 read_memory_nobpt): Remove to mem-break.c.
3297 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
3300 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
3301 entry has bad register number. This change is not
3302 tested in this release, FIXME.
3304 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
3307 * value.h: Force value's contents field to be aligned to hold
3308 at least a double or a long long (if supported). This avoids
3309 doing bcopy's in and out of the contents field.
3311 (step_1): Avoid coredump under obscure circumstances when we
3314 * symtab.h (misc_info): Add field to misc function vector for
3315 any kind of cached information the target code desires. AMD
3316 29000 uses this to avoid repeating examine_function_prologue's.
3318 * coffread.c: Lint. Remove static symfile, read_section_header.
3319 core.c (have_core_file_p): Lint: remove.
3320 expprint.c (print_subexp): Lint.
3321 infptrace.c, valops.c, valprint.c: lint.
3323 Roll in changes from vxgdb-5.0.1:
3325 * symtab.h: Comment byte order of each address class. Add
3326 LOC_LOCAL_ARG for frame-relative args (960).
3327 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
3328 symtab.c, symmisc.c: ditto.
3330 * infrun.c (init_wait_for_inferior): Clear stop_signal.
3332 * remote.c (remote_resume): Error if resume with a signal.
3334 * symfile.c (prim_record_misc_function): Clear misc_info.
3335 (fill_in_vptr_fieldno): Check stub type of arg.
3337 * valops.c (value_cast): Avoid looking up names of types whose
3338 name we don't know, to prevent coredump. Sun CC produces typedef
3339 rtx and the name of *rtx is zero...
3341 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3343 Roll in changes from final AMD 29000 port (Tiemann).
3345 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
3346 for ../include/a.out.encap.h. This might not work now that BFD
3347 is separately compiled. Instead, BFD support for encap will have
3348 to translate machine type 29k into the right COFF_MAGIC.
3350 * infcmd.c: Remove references to inferior_pid that aren't used
3351 in actual ptrace calls; use target_has_execution, etc.
3352 (have_inferior_p): Remove function.
3353 (program_info): Print target info rather than "process number";
3354 avoid gratuitous messages unless from_tty.
3355 (run_stack_dummy, finish_command): Set proceed_to_finish.
3356 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
3357 main.c: Lint. Lose have_inferior_p().
3358 inferior.h (have_inferior_p): Remove, lint.
3359 (proceed_to_finish): Add flag to ask that all regs be saved
3360 by normal_stop, for the few commands that need it, speeding up
3361 serial I/O. Add comments to stop_registers.
3363 * remote-eb.c: Remove newline from breakpoint message we grep
3364 for. Never time out when running the user program.
3368 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3370 Roll in changes from vxgdb-5.0.1:
3372 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
3373 symbol in its raw form, we are processing an unlinked ".o" file.
3374 See if the target environment has assigned it an address, using
3375 target_lookup_symbol (VxWorks does), and enter it into the symtab
3378 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
3379 68k versions for a simpler version that assumes zero FP at bottom.
3380 Fixes bug of truncated stack reports.
3382 * target.h (target_lookup_symbol): Define this routine's args
3383 and result, finally.
3385 * target.c (nosymbol): Default routine for target_lookup_symbol.
3386 (target_default): Default lookup_symbol and call_function too.
3387 (files_info): Only print has_all_memory warning if a non-dummy
3390 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
3391 vx_convert_from_virtual): If target does not have floating point,
3392 zero register "values", and avoid doing cross-net conversions.
3393 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
3394 (vx_open): Rearrange code that attaches to target and reads
3395 symbols for all loaded modules, to work if some of the modules
3396 are not accessible. Add symbol_stub() and add_symbol_stub()
3397 as callbacks from catch_errors(). Allow connect attempt to be
3398 interrupted painlessly with ^C (FIXME, there are still some bugs
3399 if the interrupt happens during symbol reading.). Print
3400 final message with puts_filtered, since symbol messages are
3405 * main.c (catch_errors): Only print errstring if non-null.
3406 (command_loop): Avoid an ioctl per command to test ISATTY.
3408 * remote-vx.c (net_load): make static; avoid sophomoric msg.
3409 (vx_xfer_memory): Return correct result!
3410 (vx_files_info): Indicate whether target has float or not.
3411 (vx_lookup_symbol): Complain, not error, if target gone.
3412 (vx_open): Print "Connected" msg before disabling immediate-quit.
3413 [FIXME: lookup_symbol and vx_open changes need testing.]
3415 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
3416 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
3417 contributor lines and update copyrights to 1991.
3419 Changes from an attempted H-PUX host port:
3421 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
3422 defines PT_ATTACH and PT_DETACH but not PT_KILL.
3423 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
3424 * remote-vx.c: include <sys/time.h> for HPUX.
3425 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
3426 "core_file_command" routine to BFD regime. May not work yet.
3428 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
3430 * xgdb.c: Replace X10 version with some VJ version.
3431 (FIXME: Its copyright assignment is not on record.)
3432 * xgdb.c: Update include files to X11R4 (Xaw crud).
3433 (xgdb_display_source, create_text_widget): fix call to
3434 get_filename_and_charpos. Rewack source window stuff for X11R4
3435 (gleaned from include files, and "nm's" of binary libraries, since
3436 I had no doc available).
3437 (append_selection, append_selection_word): Disable with FIXME
3438 since R4 changed interface here.
3439 (create_buttons): Add back the old set of buttons.
3440 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
3442 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
3443 Roll VERSION to 3.94 (not yet final though).
3445 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3447 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
3448 obstack_int_grow, obstack_int_grow_fast): Eliminate
3449 cast on left of assignment, which gives MIPS cc fits and is
3452 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
3453 F_ALIAS. Use printf, not fprintf, when not passing a file
3455 (compare_opcodes): Check that identical instructions have
3456 identical opcodes, complain otherwise.
3458 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
3459 was reported by Roland McGrath.
3460 (unimp): Only match if exactly zero instruction. (Roland)
3461 (branches and traps): Generate all variations of these
3462 instructions with macros, based on a single call that defines
3463 each condition name and its binary representation.
3464 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
3466 * valprint.c (val_print_fields): Take, and use, format parameter.
3467 This means that "p/x struct" again prints the elements in the
3468 desired format. Changed callers.
3470 * stack.c (frame_info): Use filtered output, and indicate wrap
3471 points. Remove kludgy formatting designed to avoid line wrap.
3473 * utils.c (wrap_here): If the line is already full (because
3474 we had printed a long indent or long wrapped string), do an
3475 immediate newline-and-indent.
3477 * m68k-pinsn.c (print_insn_arg): Bugfix from
3478 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
3479 instruction is incorrectly disassembled as bkpt #8.
3481 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
3482 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
3483 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
3484 and then will dump core (sometimes). I traced it back to an
3485 uninitialized symfile_name in psymtab_to_symtab.
3486 (const_vol_complaint): Add quotes to message.
3487 (define_symbol): Only believe line number if gcc_compiled.
3488 Avoid allocating symbol if we will not return it.
3490 Add target strata support so that newly established targets go
3491 into their right place in the target stack (e.g. a new exec file
3492 doesn't wipe out the ability to access the running process).
3494 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
3495 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
3496 and initialize it properly in all the targets.
3498 * target.h: Document strata. Change return type of push_target.
3500 * target.c (nomemory): new function for dummy memory access.
3501 (tcomplain): Rename complain, now also used in symfile.c.
3502 (push_target): Push targets within strata. New return value shows
3503 whether new target is on top of stack or not. Always keep dummy
3505 (target_files_info): Ignore dummy target.
3507 * core.c (core_open): Warn user, and skip accessing file, if the
3508 core target is not the topmost target in the stack.
3509 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
3512 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
3513 target_ops, it doesn't belong there since we have no regs there.
3514 Change name of target from machine => memory to clarify.
3516 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
3518 * Freeze version 3.93 for release.
3520 * Makefile.dist: Handle vx-share and nindy-share subdirs
3521 properly when building gdb.tar.Z.
3523 * symtab.c: lint; add no_symtab_msg to consolidate the messages
3524 printed in various places, so I could change just one copy.
3526 * dbxread.c, coffread.c: Change references to bfd->iostream
3527 to cast to FILE *, now that BFD avoids needing types defined
3528 in other header files.
3530 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3532 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
3533 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
3534 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
3535 (actually gcc -Wall).
3537 * dbxread.c: Remove first_global_sym, last_global_sym, since
3538 they are never referenced.
3540 * defs.h (baud_rate): Declare.
3541 main.c: Define it, and add the -b option to set it.
3543 * gdb-int.texinfo: Add text on how to define a new host or target
3544 architecture, prompted by Per Bothner's questions about MIPS
3547 * gdb.texinfo: Document "complaints". Change doc of -q since
3548 gdb no longer prints the copyright and blurb if you specify a file
3549 name to be debugged (just like Emacs). Add doc for Nindy-specific
3550 command line flags for specifying target serial port and such.
3551 Update copyright to 1991.
3553 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
3554 has taken over for us the job of ripping up executable files. The
3555 crud caused Per Bothner's port to not compile.
3557 * infrun.c (normal_stop): Avoid printing "Program exited
3558 normally" if we are in batch mode. This allows a GDB which
3559 executes a program on a target system, to behave like a Unix
3560 command (input from stdin, output to stdout, no extraneous
3563 * main.c (main): Allow additional machine-dependent command line
3564 options to be specified with the ADDITIONAL_OPTIONS,
3565 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
3566 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
3567 processing to occur just before the main loop with
3568 BEFORE_MAIN_LOOP_HOOK.
3569 (main): If a "core file" argument is specified, and it is not a
3570 core file, try it as a process ID to attach.
3571 (symbol_completion_function): Attempt to cope with
3572 "show screen-" TAB, not very successfully. This needs more work,
3574 (batch_file): New function, returns whether we are reading
3575 commands from an interactive tty on stdin, or from somewhere else.
3576 Called by normal_stop since it doesn't get from_tty passed down
3577 to it like many commands do.
3579 * remote-nindy.c: Handle command line options for nindy
3581 (nindy_before_main_loop): Prompt user for tty name if they
3582 don't specify it before getting to the interactive command loop.
3584 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
3585 and -r command line options. Also add hook before main loop
3586 to make it easy to specify a tty.
3588 * TODO: More things to do, one done.
3590 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
3592 * dbxread.c: Make complaint() calls pass pointer, not struct.
3593 Add complaints about badly formatted C++ type information
3594 (const/volatile indicator, and parse errors resulting in
3595 error_type). Fix C++ virtual member fn comment.
3596 (read_struct_type): Avoid bumping pointer if we got a parse
3597 error; this prevents our walking beyond the end of a string.
3598 Terminate loop on null char as well as semicolon.
3599 (process_one_symbol): Fix the LBRAC fix so that it uses the
3600 last previous SLINE, FUN, or SO record's PC address. C++ debug
3601 symbols did not have SLINE records in a useful order compared
3602 to the LBRAC records.
3603 (define_symbol): Handle "catch" records.
3605 * symtab.c (check_stub_type): Added new complain
3606 `stub_noname_complain' and added a consistency check to
3607 keep the debugger from crashing when finishing from an
3608 exception frame. A real fix will be needed later.
3610 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
3612 * infcmd.c (attach_command): Make global.
3614 * Makefile.dist (REMOTE_OBS): Make these compile by default,
3615 but make them easy to comment out. Perhaps later they should
3616 be enabled by what CPU you configure for? FIXME.
3617 (VERSION): Roll to 3.93.
3618 (pinsn.o): Remove rule for obsolete file.
3619 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
3621 Run down a problem that manifested by printing the wrong function
3622 name in stack traces of read_ofile_symtab. Turned out that the
3623 problem was the SunOS 4.1.1 (and previous) C compiler outputs
3624 the LBRAC symbol with an address in the *data* segment, which
3625 blew our binary search through the blocks.
3627 * dbxread.c: Use the complain() facility consistently to bitch
3628 about problems in the symbol file we are reading.
3629 (finish_block): Add code to check the nesting of the blocks;
3630 complain and Procrust them to fit if wrong.
3631 (make_blockvector): Check the order of the blocks, complain
3632 [but don't cope] if wrong.
3633 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
3634 symbols to be sure their PC value is greater than the last SLINE
3635 (line number) symbol we've seen, complaining and adopting the
3636 SLINE PC value if wrong.
3638 * symfile.h (struct complaint, complaint_root, complain,
3639 clear_complaints): Add.
3640 * symfile.c (complain, complaint_root, clear_complaints): Add
3641 facility to deal with non-fatal complaints and to regularize their
3643 (symbol_file_add): Clear complaint counters to allow new complaints.
3644 (initialize_symfile): Add 'set complaints' and 'show complaints'.
3646 * dbxread.c (dbx_symfile_read): Remember the address and size
3647 of the string table for the main symbol file, so we won't read it
3649 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
3650 to avoid reading the string table yet again. Lint.
3651 (throughout): Improve filtered output, including word wrap.
3652 (read_range_type): Improve Bothner's fix to handle other types too.
3654 * utils.c: Improve line wrap implementation. Handle unlimited
3655 width by making chars_per_line unsigned.
3656 (puts_filtered): New, easy, function.
3658 * defs.h (puts_filtered): add.
3660 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
3661 call the identical sort_symtab_syms() in symfile.c instead.
3663 * expread.y: Suggest the `file' command rather than `symbol-file'.
3665 * command.h (enum var_types): Add zinteger for seroable
3667 * command.c (do_setshow_command): Handle var_zinteger. Restructure
3668 nested if's into a switch.
3670 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
3671 we did not stop because of a breakpoint (it must have been for
3672 some other reason, like a "stepi"), so don't print anything.
3674 * symtab.c: Include <sys/types.h> all the time. Now that BFD
3675 doesn't include <sys/types.h>, old SunOS's require it for
3678 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
3680 A test port of gdb-3.92.6 to the Sony NEWS.
3683 Don't normally link in remote- or vx stuff.
3684 Some of it doesn't compile, and it wastes space for 99% of the users.
3685 Remove reference to no-longer-used HAVE_VPRINTF.
3686 Fixed BFD_DEP typo to BFD_DIR.
3688 Fix cast in arg to bfd_h_getlong.
3689 Make char *prefix be const.
3690 Fix how certain range types are mapped into builtin unsigned int types.
3692 Remove 2 #includes. They cause errors (on Sony, at least),
3693 and aren't needed (they wern't in earlier versions).
3695 print_address_symbolic should never demangle labels
3696 (since it prints *assembler-level* labels).
3698 [This was superseded by the change to printcmd below.]
3701 Add some "volatile" return types to avoid warnings.
3702 If MISSING_VPRINTF add vprintf function and not just macro
3703 (since vprintf is used in printcmd.c).
3705 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
3706 (The latter isn't grokked by some PCC-based compilers.)
3708 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
3710 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
3711 * nindy-share/coffstrip.c
3712 Added some forward declarations (otherwise, gcc complains
3713 about implicit extern redefined as static).
3715 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
3717 Changes inspired by Per Bothner:
3718 * printcmd.c (print_address_symbolic): Take additional parameter
3719 specifying whether to demangle.
3720 (print_address): Pass in asm_demangle to control demangling.
3721 (print_address_demangle): New fn, takes explicit arg to control
3723 * utils.c: Add new vars demangle and asm_demangle, and let them
3725 (fputs_demangled): If !demangle, just print the argument.
3726 (fprint_symbol): If !demangle, just print raw symbol.
3727 * valprint.c (val_print): Call print_address_demangle rather than
3728 print_address, to cause demangling to depend on the global
3729 rather than assembler-level demangling setting.
3730 * WHATS.NEW, gdb.texinfo: Document.
3732 * main.c (show_command): Show all settings if no arg.
3733 (initialize_main): Make "info set" the same as naked "show".
3734 * command.c (cmd_show_list): Handle prefix commands in the
3735 list, and print the name of the setting as well as its English
3736 description and value.
3738 Allow gdb functions to specify where a line should wrap if it
3739 exceeds the size of a terminal line. Use it to make the output
3741 * utils.c (set_screen_width_command): New fn, mallocs a buffer
3742 of the right size when screen width changes.
3743 (set_screensize_command, screensize_info): Remove #if 0'd fns.
3744 (wrap_here): New fn, indicates a point in the output where we
3745 should wrap the line rather than just letting it overflow at a
3747 (fputs_filtered): Implement wrapping.
3748 (n_spaces): New fn, returns a pointer to N spaces.
3749 (print_spaces_filtered): Use n_spaces.
3750 * defs.h (n_spaces): Declare.
3751 * stack.c (print_frame_info): Wrap with 4-space indent after
3752 fn name and before filename and line number.
3753 * printcmd.c (print_frame_args): Wrap with 4-space indent
3754 before each argument name is printed.
3755 * valprint.c (value_print): Wrap with no indentation before
3757 (val_print_fields): Wrap with indentation relative to nesting
3758 level before each field name.
3759 (val_print): Wrap with nesting indentation before array elements.
3760 * command.c (do_setshow_command): Avoid extra newlines,
3761 wrap with 4-space indent around values printed, end with period.
3762 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
3764 * breakpoint.c (breakpoint_1): Implement addressprint for
3765 "info breakpoints" display. Change file name and line number
3766 format to " at file:nnn" rather than " (file line nnn)".
3767 * gdb.texinfo: Document.
3770 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3772 Frozen for gdb-3.92.6 release.
3774 README, WHATS.NEW: Update for 3.92.6 release.
3776 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
3777 coffread.o from configs since it is now built by default.
3778 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
3779 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
3780 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
3781 from configs since it is now built by default.
3783 Makefile.dist: Update for release 3.92.6. Handle files that
3784 have been moved to ../include, ../getopt, or ../bfd. Add
3785 saber.suppress and tests directory. Add config.status to
3786 the release (it will say "none").
3788 coredep.c: Minor formatting fixes.
3790 These changes were made in early December but only checked in now:
3791 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
3792 nindy-share/nindy.c: lint
3793 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
3794 register values coming back from the target; we store values
3795 in target byte order everywhere.
3797 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
3799 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
3801 * valprint.c (cplus_val_print, val_print_fields): New functions,
3802 which print C++ objects. They conspire to avoid printing a
3803 virtual base class more than once, following all the twists and
3804 turns of C++ virtual base rules.
3805 (val_print): Call the above rather than do it by hand.
3807 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
3808 symbol file, not for added files like shared libs. This really
3809 needs to be generalized to a timestamp per file.
3811 * core.c (cleanup_core): Avoid coredump if no core file.
3813 * config.gdb: Accept -host or -target in place of +host or
3816 * coffread.c (find_linenos): Avoid desupported BFD interface
3817 to line numbers. We still read them manually rather than using
3818 BFD's "generic" features.
3820 * gdbrc.tex, threecol.tex: Add GDB reference card and its
3822 Makefile.dist: Add refcard to OTHERS list for creating tar files.
3824 * Makefile.dist: Eliminate use of $< in explicit targets.
3826 * readline/Makefile: Use $< rather than $*.c, which does not
3827 include the VPATH in GNU Make.
3829 * tconfig/i960-bout, tconfig/i960-coff: These are identical
3830 copies of tconfig/i960, added for global configuration
3831 compatability. All i960 versions can read both coff and b.out.
3833 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
3834 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
3837 * TODO: Think of more things to do.
3839 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
3841 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
3842 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
3843 64-bit float conversion.
3845 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
3846 equivalent to sun?os4 so global config works.
3848 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
3850 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
3852 * main.c: Only declare linesize once; declare pagesize not at
3853 all, since it is never used.
3854 (main): Clear newly allocated line before it is used.
3856 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
3858 Further stabilization for the Intel 960.
3860 * Makefile.dist: Parameterize the location of the "include"
3861 and "bfd" directories, as well as "getopt". Add symfile.c.
3862 Link in both dbxread and coffread. Fix up "make depend" to
3863 rewack the locations of include, bfd, and getopt in its output.
3865 * README: Document moving include files, improve some of
3868 * coffread.c: Move common code out to symfile.c. Change
3869 symbol_file_command style interface to use new *_symfile_init
3870 and *_symfile_read interface under BFD. Use BFD internal
3871 info to locate line table, symbols, etc.
3873 * core.c (core_fetch_registers): Rename to get_core_registers
3874 to avoid confusion with fetch_core_registers.
3875 (register_addr): Move to coredep.c, which is already machine
3876 dependent. This leaves core.c pretty clean of dependencies.
3878 * coredep.c (register_addr): Accept this routine from core.c.
3880 * dbxread.c: Move common code (with coffread.c, etc) into new
3881 symfile.c. Each psymtab now contains a pointer to the
3882 format-dependent function that knows how to read it in. Make
3884 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
3885 (process_one_symbol): Add code to complain about a "compiler bug
3886 we muzzle here", if we actually see it.
3888 * eval.c (evaluate_subexp): Insert missing "break" statements
3889 in code that determines whether a variable is an lvalue in
3890 memory, register, or whatever. I detected this via a compiler
3891 bug in which it *almost* mashed out the whole switch statement.
3893 * gdb-int.texinfo: Add minor sections on configuring gdb for
3894 release, and about the README file.
3896 * infcmd.c (registers_info): Fix formatting somewhat. Still
3897 not as pretty as before, but it handles byte swapping.
3899 * remote-nindy.c: If data cache routines are interrupted while
3900 waiting for the remote end, be sure that any uninitialized cache
3901 blocks are on the free list, not on the valid list!
3903 * symfile.h: Flesh out this header file with all the various
3904 routines and variables that have been merged in from dbxread.c
3905 coffread.c, and symtab.c to symfile.c.
3907 * symfile.c: New file, containing code common to dbxread.c,
3908 coffread.c, and some code from symtab.c. All generic code for
3909 reading symbol files should be in here now.
3910 (unrecord_misc_function): Remove unused function.
3912 * symtab.h: Remove file-reading things to symfile.h.
3914 * symtab.c: Remove file-reading things to symfile.c.
3916 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
3917 to decode i960 fault types.
3919 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
3920 target.c: Change type of the "resume" function from int to void,
3921 since its result was never used.
3923 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
3925 * main.c: Replace "stupid" with "caution"; you now "set caution
3928 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
3930 * infcmd.c (do_registers_info): Call val_print to deal with the
3931 byte order of the registers being printed. FIXME, this makes
3932 the formatting of the output uglier.
3934 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
3935 defined, call it for signals the debugger doesn't itself use.
3936 The i960 uses this for more detailed fault information.
3938 * remote.c (remote_open): If arg is null, print help rather than
3941 * sparc-xdep.c (register_valid): Avoid declaring size, since
3942 various modules will think of various sizes depending on the
3943 architecture of their tm-file. FIXME, we need protection against
3944 actually entering one of those modules, which would clobber
3945 storage if not for the target architecture compiled into gdb.
3947 * stack.c (up_command, down_command): Always print the frame
3949 (up_silently_command, down_silently_command): New commands
3952 * i960-pinsn.c (reg), i960-tdep.c: Lint.
3954 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
3955 more parameters than it used to.
3957 * findvar.c (registers): Increase slop to 256 bytes, which should
3958 protect us against even most RISC machines with large register
3960 (locate_var_value): Move declaration inside related ifdef.
3962 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
3963 throughout, to avoid throwing away buffered input from the board.
3964 (nindy_wait): Supply_register takes addr_of_value, not value.
3965 (i960_print_fault): Renamed from i80960_fault.
3966 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
3967 (nindy_store_registers): Avoid regs_changed stuff, just stuff
3969 (nindy_create_inferior): Don't bother to write PC_REGNUM since
3970 we can set the PC in the call to proceed(). Unpush nindy_ops
3971 before pushing it on top, to avoid message to user. Eliminate
3972 commentary from Unix machines that just misleads here.
3973 (reset_command): Fix error message to suggest target command.
3975 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
3977 Release 3.92.5 as frozen.
3979 Stabilize the merged release...with help from lint, Saber C,
3982 Everywhere: Add include files needed to declare return types
3983 of functions called.
3985 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
3987 * breakpoint.h: Add undeclared breakpoint functions, and some
3988 functions for display handling since I couldn't think of a better
3991 * breakpoint.c (insert_breakpoints): Make code for disabling
3992 shared library bkpts more likely to work. It's used when we
3993 rerun a program and stop before the shared library has been
3995 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
3996 cast from pointer, so it squeezes through catch_errors.
3997 (bpstat_stop_status): Fix logic broken some time ago. We now
3998 always create a bpstat if the stop address matches a breakpoint,
3999 even if we don't stop there -- just like the old code used to do
4000 before I got my fingers into it (sigh).
4001 (breakpoint_1): Print "ignore count" after "stop only if"
4002 condition, since that's how it actually works.
4003 (mention): Handle watchpoints as well as breakpoints.
4004 (watch_command): use set_raw_breakpoint and mention to do most
4005 of the work (and initialize all the fields!). Only pass one
4006 arg to parse_c_expression, since that's all it takes.
4008 * command.c (not_just_help_class_command): Rename arg to args
4009 since we ignore "unused argument" warnings on vars named "args".
4010 inflow.c (child_terminal_info): ditto.
4011 infptrace.c (kill_inferior): ditto
4012 main.c (catch_errors, version_info, quit_command, pwd_command,
4013 source_command, dump_me_command, editing_info,
4014 set_history_size_command, set_history, show_history,
4016 stack.c (locals_info): ditto
4017 target.c (target_files_info): ditto
4018 valprint.c (set_input_radix, set_output_radix): ditto
4020 * core.c: Remove old variables for handling core and exec file
4021 sections (data_start, data_end, stack_start, stack_end,
4022 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
4023 text_end, exec_data_start, exec_data_end, text_offset,
4024 exec_data_offset, data_offset, stack_offset). They're
4025 superseded the more general build_section_table and
4027 (get_exec_file): Mention the `file' command.
4028 (read_memory_check): Rename to memory_error, and only call it
4029 in the case of an actual error.
4030 (read_memory, write_memory): call memory_error.
4031 (core_fetch_registers): Register section name is ".reg".
4033 coredep.c: Remove a bunch of crud now that all this file does
4034 is pull the registers out of a core file.
4035 (fetch_core_registers): Rewrite to actually work, I hope.
4037 dbxread.c: Use a.out.gnu.h, not system a.out, now.
4038 Replace index() with strchr(). Remove all the pre-BFD macro
4039 definitions for accessing the symbol file.
4040 (struct dbx_symfile_info): Encapsulate the information that
4041 dbx_symfile_init needs to pass to dbx_symfile_read in this
4044 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
4045 dbx_symfile_discard): Rearrange symbol file reading to divide
4046 the format-specific part from the format-independent part,
4047 leaving the format-independent part such as file name expansion
4048 and opening in symtab.c. This replaces
4049 partial_symbol_file_open and partial_symbol_file_read.
4050 Symbol_file_read, add_file, add_file_target_command,
4051 add_file_addr_command move to symtab.c. Pass an explicit
4052 "mainline" flag for when reading the main symbol table, rather
4053 than relying on the offset address to be zero or nonzero.
4055 (dbx_symfile_read): Don't allow void *'s to be printed as
4057 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
4058 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
4059 macro" debug version really work.
4060 (read_dbx_symtab): Remove unref'd parameter inclink.
4061 Avoid swapping N_SLINE symbols, for speed.
4062 Merge N_TEXT!N_EXT case with the other external symbol
4063 definitions' case. Add comments.
4064 (start_psymtab): Allocate the symfile name in the psymtab on
4065 the psymbol_obstack, rather than using the caller's storage.
4066 (end_psymtab): Only allocate a dependencies list if there are
4068 (psymtab_to_symtab_2): Use BFD when reopening file to read
4069 its symbols for real.
4070 (read_struct_type): Add FIXME comments where it needs work
4072 (read_huge_number): Add FIXME about overflows.
4073 (read_range_type): Add FIXME about comparing a long to 1<<32.
4075 * coffread.c: Minor changes to move things closer to the new
4076 regime with symtab.c and dbxread.c Major work is still needed
4079 * exec.c (exec_file_command): Remove old variables (see core.c
4081 (xfer_memory): If memory transfer is right at the end of a
4082 section, don't lose.
4084 * findvar.c (get_saved_register): If value is in a real
4085 register, LVAL is lval_register, not lval_memory.
4087 frame.h: Declare print_sel_frame and record_selected_frame.
4089 gdb-int.texinfo: New file, for GDB internals documentation.
4090 Very simple, unformatted doc of cleanups is there for now.
4092 gdbcore.h: Remove obsolete variables that described a.out
4093 section addresses and offsets. (See core.c above.)
4094 Declare fetch_core_registers and registers_fetched.
4096 getopt.c: Declare char *alloca(); even on SPARC.
4098 infcmd.c (run_command): Call target_kill rather than
4100 (step_command, next_command, stepi_command, nexti_command):
4101 Declare from_tty parameter even though we don't use it.
4102 (run_stack_dummy): argument BUFFER is a char array, not
4103 a pointer to REGISTER_TYPE.
4104 (finish_command): using_struct_return needed a value *,
4105 not a struct symbol *.
4107 * infptrace.c (child_xfer_memory): To avoid dependency on
4108 where sections are in memory, try PT_WRITE_D and if that fails,
4109 try PT_WRITE_I. Most Unixes don't care which you use.
4111 * infrun.c (step_resume_break_shadow): Change to array to
4112 match other breakpoint shadow storage.
4113 (clear_proceed_status): Pass address of bpstat to
4114 bpstat_clear, not the bpstat itself.
4115 (child_create_inferior): FIXME comment about if the child
4117 (start_inferior): Remove old function.
4118 (child_open): Use target_kill rather than kill_inferior.
4119 (wait_for_inferior): Ditto.
4120 (insert_step_breakpoint, remote_step_breakpoint): Use
4121 new step_resume_break_shadow.
4123 * inftarg.c (child_wait): If all child processes die,
4124 pretend that the one being waited for exited with signal 42.
4126 * main.c (command_line_input): When scanning for comments,
4127 don't coredump on unclosed quotes.
4128 (quit_command): Use target_kill rther than kill_inferior.
4129 (_initialize_main): Rename class_user from "user" to
4132 * printcmd.c (print_command_1): Initialize "fmt" if no format
4133 is specified by the user.
4134 (print_frame_args): Only add to args_printed if we are
4135 actually fetching args from the stack (avoiding undefined
4137 (_initialize_printcmd): Remove bogus \{ from string.
4139 * remote-eb.c (eb_open): Avoid coredump on no argument.
4141 * remote-nindy.c: Bring out of Intel environment into new
4142 target environment. Remove all conditional compilation on
4143 I80960. Massive hacking throughout.
4144 (nindy_xfer_inferior_memory): New routine stolen from
4146 (nindy_create_inferior): New routine pieced together, probably
4147 not quite working yet.
4148 (nindy_ops): New target_ops struct for nindy.
4150 * remote-vx.c: Use write_memory rather than target_write_memory
4151 to get error checking.
4152 (vx_add_file_command, vx_open): Use symbol_file_add rather than
4154 (vx_create_inferior): Use target_terminal_ours...
4156 * signame.c (_initialize_signame): Always initialize, since
4157 we need the table for things other than psignal.
4159 * solib.c (solib_add): Use symbol_file_add, not add_file.
4160 (solib_address): Return boolean result rather than struct
4161 pointer which nobody else knows the type of.
4163 * sparc-tdep.c, valops.c: Use write_memory rather than
4164 target_write_memory, to get error checking.
4166 * stack.c (locals_info, catch_info, args_info,
4167 get_selected_block, frame_command, up_command): Use
4168 target_has_stack, rather than have_inferior_p or
4171 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
4173 * symfile.h: New file, defining the interface between the
4174 generic and object-file-specific symbol reading code.
4176 * symtab.c: Move generic symbol-reading interface to symtab.c,
4177 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
4178 table to map BFD targets to symbol-reading modules in GDB.
4179 Change index to strchr.
4180 (lookup_struct_elt_type): Use error() rather than hand-made
4181 simulations thereof.
4182 (lookup_partial_symbol): Speedup slightly when length == 0.
4183 (symbol_file_add): New function.
4184 (symbol_file_command): Call it.
4185 (symfile_open, symfile_init): New function.
4186 (add_file_target_command, add_file_addr_command): moved from
4189 * target.c (target_command): use target_kill.
4191 * target.h (target_files_info): Don't declare, never called
4194 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
4195 files to determine stack end address.
4197 * valarith.c (value_x_binop, value_x_unop): Change error message
4198 to be more useful. Pass proper argument to value_struct_elt.
4200 * valops.c (value_assign): FIXME comment that long long
4201 bitfields will break here.
4203 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
4204 Update `make saber_gdb' to work better.
4206 * TODO: A woman's work is never done.
4208 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
4209 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
4210 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
4211 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
4212 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
4213 valops.c, valprint.c, exec.c: Lint.
4216 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
4218 Continuing Intel 960 port merge of GDB.
4220 * Makefile.dist: Merge i960 "nindy-share" files. Rename
4221 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
4222 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
4223 Wack over "make depend" so it handles files in subdirectories
4224 vx-share, nindy-share, bfd, and in the current directory.
4226 * blockframe.c (get_prev_frame_info): Remove fatal error
4227 if stack not defined.
4229 * core.c (core_open, core_detach): New functions that handle
4230 the old "core-file" command as "target core" and "detach" instead.
4231 (core_file_command): Call them.
4232 (core_xfer_memory): Use common routine xfer_memory.
4234 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
4235 dbxread now uses bfd for everything but symbol reading itself.
4236 BFD internals are used to drag out the relevant file offsets.
4237 (partial_symbol_file_open): Change args all around for BFD.
4239 * symtab.c: Rename "value" to "val" everywhere, so we can
4241 (symbol_file_command): New command, moved from dbxread.c
4242 and coffread.c. It uses BFD to read the file, then vectors
4243 based on its type, to dbx or coff symbol readers.
4244 * symtab.h: Extern a few vars for symbol_file_command.
4246 * target.h: Breakpoint takes a char * save area, not a char **.
4248 * valprint.c (val_print): When unpacking bitfields, offset
4249 the address in gdb of the value, if it is declared with a shorter
4250 type. Remove the last "runtime kludge test" of host byte order.
4252 * utils.c: Remove old my_bfd_read routine.
4254 * stack.c (frame_info): Use target_has_stack. Print program counter
4255 register's actual name rather than "pc", since it's called the
4256 "ip" (instruction pointer) on the i960 (sigh).
4258 * target.c (target_command): Add command for selecting a target
4259 type and calling its open routine. This is used for initiating
4260 communication with a particular target, in a generic way.
4262 * tm-i960.h: Update for modern gdb. Remove semicolons from
4263 various macros. Handle reading struct return convention, and
4264 error-out attempts to return structs with the "return" command.
4265 Be sure gdb doesn't think we know how to call functions in the
4268 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
4269 to i960_xxx in lower case.
4270 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
4271 not being defined yet.
4273 * remote.c (remote_open): Call start_remote to initialize
4274 wait_for_inferior during open.
4275 (remote_xfer_inferior_memory): Return length written rather
4278 * remote-vx.c (target_command -> vx_open): Use new generic
4280 * remote-eb.c, inftarg.c, exec.c: ditto.
4282 * infrun.c: Fix comments.
4283 (attach_program -> child_open): Use new generic target command.
4284 (wait_for_inferior): Clear saved register values before target_wait,
4285 so target_wait can set some of them if convenient.
4287 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
4288 Return success indicator, not void.
4289 (child_xfer_memory): Avoid fetching initial word if we'll
4290 overwrite it anyway.
4292 * infcmd.c (attach_command): Use new generic target open routine.
4293 (_initialize_infcmd): Update doc on attach and detach commands.
4294 (do_registers_info): Merge in a byte-order problem as a FIXME
4297 * findvar.c (find_saved_register): Avoid problem in current frame.
4298 (read_relative_register): Ditto.
4299 (write_register): Convert byte order on the way out.
4301 * exec.c (file_command): Add.
4302 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
4303 (xfer_memory): Common function between core_xfer_memory and
4305 (exec_xfer_memory): Use it.
4307 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
4309 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
4310 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
4311 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
4313 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
4315 Merge Intel 960 port of gdb, continuing...
4317 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
4318 symbol_file_command): Pass from_tty arg to hush 'em up.
4320 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
4321 Add magic numbers for 960 COFF format.
4323 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
4325 Merge Intel 960 port of gdb, from Intel "1.2" release.
4327 CHANGE_LOG entries from their port, which was based on
4330 Thu Sep 6 11:02:22 PDT 1990
4331 Remove temp file if download is interrupted.
4333 Wed Aug 1 09:08:33 PDT 1990
4334 Now uses binary protocol to talk to NINDY.
4335 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
4336 Times out after 5 seconds when trying to talk to NINDY.
4338 Tue May 29 12:54:49 PDT 1990
4339 Added variable baud rate (-b switch).
4340 Source code reorganization.
4342 Thu Apr 26 11:09:55 PDT 1990
4343 More cleanup of batch mode; specifically, execute "-s", "-e", and
4344 "-se" switches as soon as they are encountered on the invocation line.
4346 Fri Apr 20 13:47:15 PDT 1990
4349 Thu Apr 19 09:54:28 PDT 1990
4350 Add 'reset' command.
4352 Wed Apr 18 09:48:07 PDT 1990
4353 After opening remote tty, wait for 1 second to go by without input
4354 from it before trying to talk to NINDY (fixes problems with the
4355 Heurikon HK80/V960E).
4357 Mon Apr 4 16:33:05 PDT 1990
4358 Some output was not being suppressed in 'batch' mode.
4360 Thu Mar 22 15:31:11 PST 1990
4361 Ask user if old symbol table should be deleted when new file is
4364 Allow user to run a program downloaded before gdb960 was brought up.
4366 Correct "exec-file" help message for i80960 context.
4368 Correct bug in calculating user space address: could occasionally
4369 corrupt user program.
4371 Make sure to zero low-order bits in rip's because of bug in 960CA
4372 A-step part: could cause operation faults when "next"ing across
4375 Correct bug that made it impossible to get source line numbers for
4376 code loaded at addresses higher than 0x7fffffff.
4378 Wed Jan 10 12:43:22 PST 1990
4379 Open remote tty for exclusive use.
4381 Fri Jan 5 12:14:42 PST 1990
4382 Correct disassembly (CA manual was right after all):
4383 opcode for sysctl is 0x659
4385 Mon Oct 23 12:03:04 PDT 1989
4386 Use G960BASE and G960BIN environment variables to find 'sx' utility.
4388 Mon Oct 16 14:15:09 PDT 1989
4389 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
4391 Mon Oct 2 15:56:31 PDT 1989
4393 Added 960CA disassembly support.
4395 To simplify maintenance:
4396 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
4398 - eliminated opcode.h: incorporates tables into i960-pinsn.c
4399 - moved 960-specific routines from i960-pinsn.c to i960-md.c
4400 - made disassembly interface identical to that in gdmp960.
4404 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
4406 * target.h: Allow targets to stack. Add target_has_memory,
4407 _registers, etc. Restructure memory access and "info files"
4408 to walk the target stack.
4409 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
4410 target.c: Change tables to match target.h.
4411 * inflow.c (child_mourn_inferior): pop child_ops.
4412 (generic_mourn_inferior): Use new has_stack flag.
4413 * infptrace.c (child_xfer_memory): New memory regime.
4414 * inftarg.c (child_files_info): New "info files" regime.
4415 * remote-eb.c: New memory regime, new info files.
4416 * remote-vx.c: New memory regime, new info files. Now use
4417 separate targets for VxWorks attachment to machine, and
4418 actually running a process under VxWorks, since one has
4419 stack & execution & regs and the other doesn't.
4420 * remote.c: New memory regime, new info files.
4421 * sparc-xdep.c (fetch_core-registers): New memory regime.
4422 * target.c: New routines and support for stacked targets,
4423 new memory regime, new info files regime.
4426 Generalize section handling for an arbitrary number of sections,
4427 including use of the new BFD (binary file) library.
4428 * gdbcore.h: Add struct section_table.
4429 * exec.c (build_section_table): Iterate all sections and
4430 record what gdb needs to know about them.
4431 (exec_command): Use it.
4432 (exec_xfer_memory): Use the table.
4433 (exec_files_info): Print the table.
4434 * core.c (core_file_command, core_xfer_memory, core_files_info):
4436 * source.c (find_source_lines): Use bfd_get_mtime.
4437 * dbxread.c: Quick changes to make it compile with new BFD.
4438 * utils.c (error): Avoid using bfd_error in generic routines.
4440 * core.c (core_fetch_registers): Get from the ".regs" section of
4442 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
4444 * inferior.h (attach_flag): Export.
4445 * infcmd.c (run_command): use new target_create_inferior.
4446 * infrun.c (child_create_inferior): Don't return result.
4447 * Makefile.dist (VERSION): 3.91.4.
4449 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
4451 * breakpoint.c (bpstat_num): Handle breakpoints which have
4452 since been deleted, such as temporary breakpoints.
4453 infcmd.c (program_info): ditto.
4455 * core.c (core_file_command): Display the frame where the core
4460 * remote-vx.c (target_command): Merge in target command from
4461 targ-vx.c. A few other cleanups.
4463 * TODO, Projects: Lots more stuff to do...
4465 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
4467 Massive changes to wall off the remote-debugging interface
4468 behind a function vector. The port to handle VxWorks targets
4469 is also part of this.
4471 All files: Replace references to renamed functions,
4472 remove references to remote_debugging, remove references to
4473 have_include_file, have_core_file in favor of target_has_stack,
4474 target_has_memory, etc.
4476 * Modularize the breakpoint interface.
4477 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
4478 a breakpoint instruction.
4479 breakpoint.c: struct breakpoint's shadow_contents now sized as
4481 (insert_breakpoints): Vector to target to install breakpoints.
4482 (remove_breakpoints): Vector to target here too.
4483 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
4484 sparc-tdep.c (single_step): Use new breakpoint interface for
4485 the single-step breakpoints.
4486 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
4487 New file, contains routines to insert and remove breakpoints by
4488 reading out the old contents and later replacing them. This is
4489 how ptrace breakpoints work, and many remote systems as well.
4491 * tm-vxworks68.h: New config file, overrides a few things for
4492 Wind River's preferences.
4494 * target.h: New file, for transfer vector used to talk to the
4495 inferior (child, attached, core, exec, remote, etc). All accesses
4496 to the thing being debugged should come through these vectors.
4497 target.c: New file, routines to handle transfer vector.
4498 (various files): Add transfer vectors XXX_ops for the various
4499 targets and pseudo-targets (core files, etc) we support.
4501 * breakpoint.c (bpstat_stop_status): Further explorations of
4502 watchpoints and why things don't work all the time.
4503 (bpstat_alloc): New fn to allocate a bpstat and chain it.
4505 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
4506 the local gdbinit if it doesn't already have it.
4508 * core.c (core_ops): add and install.
4509 Allow core debugging without exec file.
4511 * dbxread.c (free_and_init_header_files): Merge two fns.
4512 (end_symtab): Free named symbol table when a new version comes in.
4513 (read_dbx_symtab): Relocate all kinds of symbols with base
4514 address. First step toward handling different text, data, bss
4516 (add_file_addr_command): Renamed add_file_command.
4517 (add_file_command): Vector to remote handler.
4518 Add "load" as an alias for "add-file" command.
4520 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
4521 non-returning functions.
4523 * exec.c: Add exec_ops, and push it as a target when an exec
4526 * infcmd.c (run_command): Pass executable file name and arg list
4527 separately when starting an inferior. Permit "run" when no exec
4528 file is specified, for VxWorks.
4529 (detach_command): Move to child_detach in inftarg.c.
4531 * inftarg.c: New file. Unix-child-specific routines, and the
4532 child_ops structure.
4534 * inferior.h (registers): Export "registers" as the way for
4535 target dependent register handlers to find gdb's local copy of
4536 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
4537 since it is now used by places that want wait_for_inferior to
4538 handle the grunge but want to see every trap from the inferior.
4540 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
4541 Eliminate remote_debugging hooks in terminal handling.
4543 * infrun.c: Replace start_inferior with child_create_inferior.
4544 Move all the hair of Unix shells and ptrace idiosyncracies into
4545 child_create_inferior, so remote handlers don't have to deal.
4546 Remove running_in_shell. Rename stop_after_attach to
4547 stop_soon_quietly, and use it in a few other places where we want
4548 to just call wait_for_inferior and get control back on the first
4549 trap. trap_expected now never takes a value > 1.
4550 (init_wait_for_inferior): Initialize static vars when a new
4553 main.c (gdbinit): Add new hook for .gdbinit file name, let
4554 it be overridden by config files as GDBINIT_FILENAME.
4555 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
4556 Both of these are used for VxWorks gdb.
4558 mcheck.c: rename include file "gmalloc.c" to avoid problems
4559 with system include file "malloc.c".
4561 param-no-tm.h: New include file, same as param.h but does not
4562 include the default "tm.h" file. This is used in files where
4563 the target is known, e.g. remote-eb.c or sparc-xdep.c.
4565 param.h: Now just a shell that includes tm.h and param-no-tm.h.
4567 remote-vx.c: New file, VxWorks remote debugging support. Uses
4568 RPC routines that are shared with the target system, in directory
4571 remote.c: Vectorize remote interface.
4573 source.c: Globalize source_path, and make an alias "l" for "list"
4574 since we now have the "load" command.
4576 sparc-xdep.c: Use new param-no-tm.h.
4578 symmisc.c (free_named_symtab): Add new function from Wind River.
4579 However, ifdef it out for now while we think about what it should
4582 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
4584 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
4585 non-Unix-children handle this with their own code in the target
4588 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
4589 source and target lists. Add vx-share to default list of include
4590 directories. Add new files to src and target lists: mem-break,
4591 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
4592 ${srcdir} versions of munch and createtags are used.
4594 * valops.c (find_function_addr): Split out of call_function.
4595 (call_function_by_hand): Rename call_function; this function
4596 calls functions in the target by laboriously patching the target
4597 word-by-word with the right stack, args, regs, etc.
4600 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
4602 Handle AMD 29000 a bit better.
4604 * remote-eb.c (readchar): Mask received char log to make it readable.
4605 (remote_start): Pass arguments down to executing program.
4606 Make startaddr unsigned.
4607 infrun.c (start_inferior): Accept args, pass them to
4609 infcmd.c (run_command): Pass args down to start_inferior.
4611 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
4612 the target object file format.
4613 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
4615 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
4616 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
4618 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
4620 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
4621 * TODO: We did a few things, we have more to do though.
4623 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
4624 * inflow.c (inferior_died): Clear deferred stores.
4626 * Debug problems with dummy frames and calls to the inferior.
4627 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
4628 * sparc-tdep.c (do_restore_insn): Simplify.
4629 (sparc_frame_find_saved_regs): Simplify and fix what we find.
4630 (sparc_push_dummy_frame): Simplify and fix what we push.
4631 (sparc_pop_frame): Slightly more hair here, deciding whether
4632 we are restoring a saved PC or returning to a return address in %i7.
4633 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
4635 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
4636 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
4637 * obstack.h (chunkfun): ditto.
4638 * defs.h (xmalloc, xrealloc): ditto
4640 * utils.c (quit): Grab the terminal from the child if necessary.
4642 * inflow.c (term_status_command): Rename to term_info, change
4645 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
4646 (is_delayed_branch): Speed up.
4647 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
4648 Still missing some float ops, and needs testing.
4650 * Support for input and output radixes other than base 10
4651 * defs.h (input_radix, output_radix): Declare.
4652 * expread.y (yyparse, parse_number): Handle changes of input
4653 radix, and ambiguous names-or-numbers in radixes >10.
4654 * printcmd.c (print_scalar_formatted): Print formatted hex
4655 numbers in varying column widths.
4656 * valprint.c (val_print): Use output_format to print scalar ints.
4657 (set_input_radix, set_output_radix, set_radix): Create.
4658 (set_output_radix): Set output_format from output_radix.
4659 (_initialize_valprint): add `set radix' but leave the others off.
4661 * main.c (execute_command): Let stupid questions be turned off.
4662 (_initialize_main): Handle "set stupidity", etc.
4664 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
4665 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
4667 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
4669 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
4670 bfd stuff is still screwed up, but with some manual work, it
4673 * breakpoint.c (bpstat_do_actions): Start over if a command
4674 proceeds the inferior, since the inferior will have stopped and
4675 will need to have its new stop-actions taken care of.
4677 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
4678 compiler fits, simplify it.
4680 * gdb.texinfo (directory command): Doc new dir command.
4681 source.c (directory_command): "dir" now puts things on the front
4682 of the path, moves dups up front, and handles multiple names
4683 on the command line, inserting each one in order. It also
4684 blows away cached line and full_filename info.
4686 * stack.c (backtrace_command): Skip "more stack frames follow"
4689 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
4690 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
4691 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
4692 The only odd one was Gould NP1, which had defined vprintf to
4695 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
4696 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
4697 variable, inspect_it.
4698 valprint.c (print_string, val_print): Use the global inspect_it
4699 to indicate whether to print in Epoch style or normal style.
4701 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
4703 * printcmd.c (call_command): add an alias for the "print" command
4704 which runs expressions and doesn't print the result if void.
4705 (print_command_1): implement it.
4707 * command.c: Remove #if 0'd code. Initialize all the fields
4708 in add_cmd (). Rename do_nothing_command to
4709 not_just_help_class_command, and make it externally visible.
4710 command.h: add user_commands to struct.
4711 * main.c (define_command): Don't overload c->function with a char
4712 string as well as a function pointer.
4714 * eval.c (evaluate_subexp): Reinstall tiemann changes to
4715 calling convention of value_struct_elt () that got dropped in
4718 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
4719 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
4721 * tm-sparc.h (POP_FRAME): replace some constants with defines.
4723 * sparc-xdep.c (store_inferior_registers): defer stores to regs
4724 until a good time (e.g. when we are about to run the child),
4725 saving ptrace calls.
4726 * infrun.c (proceed): handle DO_DEFERRED_STORES.
4727 * tm-sparc.h: define DO_DEFERRED_STORES.
4729 * sparc-xdep.c (store_inferior_registers): when storing float
4730 registers, don't store stack regs too. When storing the SP,
4731 however, DO store the stack regs too. This fixes a bug in which
4732 the dummy frame is not recognized when a call_function finishes,
4733 because its frame pointer (in the stack regs) was never
4735 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
4736 even though we don't know how to read them from an inferior.
4737 valops.c (call_function): Comment about storing SP.
4739 * infrun.c (save_inferior_status): Save away the original bpstat
4740 chain so it can be restored later. Install the copied version for
4741 use by whoever saved the status. It will be blow away by
4742 restore_inferior_status, and the original chain restored. This is
4743 important for people who have pointers into the original.
4745 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
4746 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
4747 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
4750 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
4752 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
4753 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
4754 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
4756 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
4758 * Merge Mike Tiemann's multiple inheritance changes from Sun.
4759 Store the baseclasses in a type struct starting from array element
4760 0 rather than from the unusual array element 1.
4762 dbxread.c: the above.
4763 (virtual_context): Add
4764 Read new debug information about which virtual function table
4765 a virtual function is from, and store it in fn_field.fcontext.
4767 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
4768 TYPE_FN_FIELD_STATIC_P.
4770 symtab.c: the above.
4771 valops.c: the above. Handle pointer casts of object *'s.
4772 (search_struct_method): Add.
4773 (value_struct_elt): First arg is now a pointer to a value, and is
4776 valprint.c: the above.
4777 values.c (value_virtual_fn_field): Add type arg. Handle
4778 offsetting to the proper object when calling virtual fns.
4780 (baseclass_addr): Add valuep arg.
4782 * README: Document the current state of BFD config (missing).
4783 * TODO, ChangeLog, Makefile.dist: Roll version.
4784 * WHATS.NEW: Add summary of changes since 3.5.
4786 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
4788 * dbxread.c (read_struct_type): Clear bit vectors whenever
4790 symtab.c (B_CLRALL): define.
4792 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
4793 using == rather than =. Huh... This fixes the dreaded problem
4794 wherein builtin_type_int becomes TYPE_CODE_FLT.
4796 * core.c (info_files): Show the inferior pid.
4798 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
4799 already knows how to look in the source directory.
4801 * Remove psymtab hair from many places. Remove duplicated code
4802 for searching symbol tables. Hide psymtabs from most places.
4803 Make it fast to get from a psymtab to its symtab.
4805 blockframe.c (blockvector_for_pc): Remove psymtab hair.
4806 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4807 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4808 dbxread.c: export psymtab_to_symtab, make it work if called N times.
4809 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
4810 new symtab completely. New psymtabs get symtab pointer
4811 initialized to zero. Remove MI warning printf.
4812 symtab.h: Comments. Add psymtab to symtab pointer.
4813 (PSYMTAB_TO_SYMTAB): New macro.
4814 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
4815 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
4817 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
4819 (print_frame_info): Avoid special-casing symbols that have not yet
4822 * source.c (open_source_file): Quick path if we have already
4823 located the source file by its full name.
4825 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
4826 find_pc_psymtab. When a name is found in the misc function
4827 vector, search the symbol table for its mangled name, not the
4828 name that the user typed.
4830 * bfd.h: Fix missing comment terminators, make #endifs match.
4832 * valarith.c (value_less): Handle unsigned int comparisons.
4833 Add FIXME about pointer compares, which assume host and target
4834 pointers are the same.
4836 * command.c (do_nothing_command): lint
4837 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
4838 fix comments on debug symbol format for visibility. Actually set
4839 visibility of symbols.
4840 main.c (echo_command): lint; use <readline/history.h>.
4841 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
4842 obstack.h (_obstack_blank): Rearrange pointer math to avoid
4843 pointing past end of allocated memory; saber complains.
4844 obstack.h: Declare the external functions that we use.
4845 valarith.h: use <string.h>
4846 solib.c (solib_add): lint.
4848 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
4850 * main.c (initialize_main): Default info_verbose to off, now that
4851 symbol reading is fast.
4852 (quit_command): Avoid clobbering exec_bfd while quitting.
4854 * Initial BFD (binary file diddling library) merger:
4855 coffread.c: Change AOUTHDR to struct exe_hdr.
4857 core.c: initialize initialized data at compile time.
4858 (core_file_command): Move from coredep.c, convert to bfd.
4859 (xfer_core_file): Convert to bfd.
4860 exec.c (exec_file_command): use bfd routines.
4862 mips-tdep.c: Remove exec_file_command and friends.
4865 * coredep.c: (fetch_core_registers) Convert core_file_command to
4866 fetch_core_registers.
4867 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
4869 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
4870 (my_bfd_read): More bogosity, which I don't think we call.
4871 (program_name): Remove this atrocity asap!
4873 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
4876 values.c: allocate_repeat_value was not clearing the
4877 optimized_out field.
4878 (value_static_field): minor stylistic fix (wrong macro was used).
4879 valops.c (value_struct_elt_for_address): didn't work for C++
4882 * signame.c (_initialize_signame): Initialize signal names once.
4884 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
4885 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
4886 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
4888 * remote-eb.c: Support user-settable baud rates on the serial port.
4890 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
4892 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
4894 * tconfig/sun3os4: Remove warning about native assembler,
4895 since it also occurs in the xconfig file.
4897 * findvar.c (registers): Allocate some slop after `registers'
4898 to prevent stray accesses from trashing the next variable.
4900 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
4901 on the sun-3, by changing the #ifdef from `sun3' (which is not
4902 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
4903 vars, which happened to follow `registers' in the executable.
4905 * readline/history.c (history_search): Heed gcc-2's advice
4906 and parenthesize && inside ||).
4908 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
4909 tm-29k.c: Insert FSF copyright headers.
4911 * remote-eb.c: Better comments.
4913 * Makefile.dist: Update to 3.91.6.
4914 * TODO: note PREPARE_TO_STORE problem.
4916 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
4918 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
4920 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
4922 * infrun.c (wait_for_inferior, at end): Don't set up
4923 prev_* if the inferior no longer exists.
4925 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
4926 CANNOT_EXECUTE_STACK.
4927 valops.c (call_function): Use it.
4929 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
4931 * inferior.h (PC_IN_CALL_DUMMY): New macro.
4932 infrun.c (wait_for_inferior, 2 places): Use it.
4934 * values.c (value_being_returned): Only use
4935 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
4937 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
4938 right thing for remote-eb.c.
4940 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
4941 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
4943 * blockframe.c: Put get_frame_saved_regs inside #if !defined
4944 (FRAME_FIND_SAVED_REGS).
4946 * findvar.c ({fetch,store}_registers): Check for
4947 REMOTE_{FETCH_STORE}_REGISTER macro.
4949 * findvar.c (get_saved_register): Add argument lval and
4950 change meaning of argument addr.
4951 findvar.c: Change calls to get_saved_register to reflect
4952 new calling convention.
4953 valops.c (value_assign): Use get_saved_register instead of
4954 find_saved_register.
4956 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
4958 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
4959 an (uninitialized) pointer to one. Use "&" when passing it
4962 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
4964 * coffread.c (getfilename): Use DGUX x_offset and x_name if
4967 * coffread.c (symbol_file_command): Put semicolon after
4969 Put safe_to_init_tdesc_context in #if defined (TDESC).
4970 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
4971 coffread.c: #include <sys/stat.h>.
4972 (read_coff_symtab): Typo: in_source_files -> in_source_file.
4973 Add missing ')' in check for "lc%" and friends. Remove
4975 Declare read_one_sym() at top of file.
4976 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
4977 MC68WRMAGIC can have the same value without causing a duplicate
4980 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
4982 * Allow a Makefile to be built without building the
4983 tm and xm file links that screw up builds in subdirectories.
4984 This is done with `config.gdb none', then you can do things
4985 like `make gdb.tar.Z'.
4986 * tconfig/none: Config file for no target system
4987 * xconfig/none: Config file for no host system
4988 * config.gdb: If no TM or XM files are called out by the
4989 host or target file, don't make links for them.
4991 * cplus-dem.c: Add documentation.
4993 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
4994 simple error, so the user's gdb doesn't crash due to some object
4995 file problem (e.g. somebody is rebuilding the file out from under
4998 * printcmd.c (print_address_symbolic): demangle the symbol.
5000 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
5001 Motorola copyrights in it. Make "make gdb.tar.Z" work.
5002 (alldeps.mak): sort and uniq all results from this; duplicates
5003 hose gdb.tar.Z link building. Remove RCS files from
5004 tconfig and xconfig. Add config files for sun386. Add
5005 a few odd files to OTHERS and HFILES.
5007 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
5009 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
5010 Roll version number to 3.91.5. Make lint work in bindir.
5012 * README: Document cross-debugging and new file structure.
5014 * blockframe.c: Lint. Include "value.h" to declare read_register.
5015 (find_pc_partial_function): remove duplicate line.
5017 * command.h: Lint. Declare error_no_arg and dont_repeat.
5019 * tm-news.h: Remove inadvertently duplicated stuff.
5021 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
5022 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
5024 * config.gdb: Allow `config.gdb host target' form. Clean
5025 up previous change that printed bogus messages when you just said
5028 * core.c: #include "command.h" for lint.
5031 * main.c: Remove some casts of enums. Lint.
5038 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
5040 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
5041 read it from memory. This will allow us to save ptrace calls
5042 eventually. Changed caller single_step too.
5044 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
5045 that we aren't going to use, saving many ptrace calls, especially
5046 when watchpointing or single stepping. Use some #define's for
5048 (store_inferior_registers): Ditto.
5049 (core_file_command): Use some #define's for constants.
5051 * tm-sparc.h: Add #define's for some register numbers, so we
5052 can eliminate the use of random constants in sparc-xdep.c.
5054 * stack.c (frame_command, print_frame_info, up_command,
5055 down_command) Remove frame_changed, since it
5056 causes a bug and doesn't seem to do anything useful. In some
5057 places it was used as a flag, in others as a stack level (?).
5059 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
5060 default is to use the portable (vprintf) version rather than the
5062 * xm-news.h (MISSING_VPRINTF): Add.
5064 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
5066 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
5068 * Remove stuff that forces -Bstatic linking of gdb, and warnings
5069 about linking debugged programs -Bstatic in the sun?os4 config
5070 files in tconfig and xconfig subdirectories.
5072 * main.c (main): Remove unreached exit(0) now that we exit
5075 * Create TODO file for online bug list. There are too many
5076 "little" bugs to keep track of on paper.
5078 * Change Projects file to refer to bug-gdb@cygnus.com
5079 rather than kingdon@ai.
5081 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
5083 * Makefile.dist (VERSION): 3.91.4 now.
5085 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
5086 (condense_misc_bunches): Add sanity check that misc_count is
5087 the same as the number of symbols in the bunch.
5089 * coffread.c: rename init_misc_bunches. Pass an argument
5090 to condense_misc_bunches (a zero).
5092 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
5093 every time we are called; don't rely on our caller to do it.
5094 (add_file): Remove call to init_misc_bunches.
5096 * mipsread.c: Only warn, don't error, if unknown symbol types.
5097 This keeps an old gdb from falling on its face if it sees newly
5098 extended symbol info. Rename init_misc_bunches.
5100 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
5102 * Merge in changes from Per Bothner for DECstations and other
5103 MIPS stuff. The rest is Bothner speaking:
5105 The next message is a merger of Alessando Forin's mips port with
5106 mine. I've tried to use my good if biased judgment to get
5107 the best of both. It *does* need testing.
5109 Some of the changes are general, *not* mips-specific.
5112 Didn't believe in little-endian bit order.
5113 There are still inconsistencies about whether flags
5114 like BITS_BIG_ENDIAN are integer (#if ...) or
5115 boolean (#ifdef ...). I tried to paper over them.
5117 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
5118 Moved some misc_function code that was common to
5119 {dbx,coff,mips}read.c to symtab.c.
5120 In the process, I think I cleaned things up a bit.
5121 At the same time, moved obsavestring and obconcat to symtab.c.
5124 Removed obsolete condense_addl_misc_bunches (use
5125 condense_misc_bunches(1) instead).
5128 Needed to include <sys/dir>, at least on DECstations.
5130 valops.c, mips-tdep.c, tm-mips.h:
5131 Added PUSH_ARGUMENTS macro to support funny argument-pushing
5132 conventions (when STACK_ALIGN is insufficient).
5133 Needed on mips, where doubles need 8-byte alignment,
5134 but ints only need 4.
5137 Removed cruft that was not being used.
5138 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
5141 Print $ before register-names (I think that makes things a little
5143 Never print two instructions, even if one delays.
5144 Removed hex-disassemble set_cmd. (This is not mips-specific,
5145 so I think the argument is whether it is generally worthwhile or not.
5146 I'm inclined to think not, given how easy it is to
5147 convert between radixes in gdb.)
5150 This is basically Alessando's code.
5151 It doesn't use obstacks; I changed it to use obstacks
5152 in a few minor places where using malloc causes a
5153 memory leak. (Probably, more places could/should be changed.)
5154 I added record_misc_function where it was missing.
5155 In symbol_file_command and add_file_command, I tried
5156 to make the code consistent with more recent versions.
5157 Minor sylistic changes in parse_procedure.
5158 Make a .gdbinfo. psuedo-symbol point back to the real
5159 procedure symbol (using the isym field).
5162 This is basically from my port, but with a lot of details
5163 and a number of routines merged in from Alessando's version.
5164 I basically used my code "raw" backtrace (use heuristics
5165 from the actual code, rather than symbol table info) - though
5166 the idea is Alessandro's. I feel my code is a little cleaner
5167 here, particularly in being a little more flexible, such as being
5168 able to handle gcc-produced code (which it now can).
5169 It also doesn't do frame caching (which is not useful
5170 more recent gdb versions).
5171 I also used my code for push_/pop_dummy, more or less.
5172 I tried to incorporate AF's code for testing sigtramp
5173 while backtracing; I probably got it wrong.
5174 Added mips_print_register, which tries to scrunch as much
5175 information as possible on a screen...
5176 Removed the skip-prologue set_cmd. As with hex-disassemble (see
5177 under mips-pinsn.c), I don't see anything mips-specific here,
5178 and I don't see it being all that useful anyway.
5181 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
5182 Use more register names (rather than hard-cases numbers).
5184 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
5186 * Hack up 3.90.11 changes:
5188 * Makefile.dist (depend): parameterize $(GCC).
5189 Add solib.c and solib.o.
5190 (readline): Fix vpath for both absolute or relative SRCDIR.
5192 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
5193 Also, let the part I didn't understand at least compile so
5194 I can test the rest. FIXME.
5196 * dbxread.c: Fix thinko using strcmp.
5197 (init_psymbol_list): declare static.
5198 (partial_symbol_file_open): Comment cleanups better, avoid
5199 cleaning up the string table since the caller will do that.
5200 Move the stat for mod time into symbol_file_command, temporarily.
5201 (There should be a mod time for each symbol file, eventually,
5202 to control its rereading. FIXME.)
5204 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
5205 SunOS, which gives error for shared libs otherwise. (From
5206 Schaefer, probably FIXME needs work for portability.)
5208 * solib.c: Move #include "param.h" to work.
5209 Lowercase all the Uppercase Letters In the Messages.
5210 (find_solib): Clean up inferior_so_name for debug printouts.
5211 Allow no argument, to mean all shared libraries.
5213 * symmisc.c: include param.h to get CLEAR_SOLIB.
5215 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
5217 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
5218 to 3.90.11. ChangeLog entries below are from this.
5220 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5224 * Makefile.dist (HFILES): Add tm-sunos.h.
5226 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5230 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
5232 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
5234 * sparc-opcode.h Added single-operand version of rett.
5236 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5238 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
5239 Put parens around gcc_p in expansion.
5241 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5243 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
5245 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5247 * Changes for Sun shared libraries:
5248 blockframe.c (find_pc_partial_function): If a non-text symbol
5249 is found, set *address = pc - FUNCTION_START_OFFSET.
5250 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
5251 Disable breakpoints instead of giving an error.
5252 source.c (select_source_symtab): Initialize cs_pst.
5253 symmisc.c: Call CLEAR_SOLIB if defined.
5254 symtab.h: Make text{low,high} CORE_ADDR not int.
5255 (psymtab): New field addr.
5257 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
5258 (record_misc_function): Give correct type for N_DATA symbols.
5259 (condense_misc_bunches): do "misc_function_count = j" regardless
5261 Take code which is shared between symbol_file_command and
5262 add_file_command and put it into partial_symbol_file_{open,read}.
5263 Split add_file_command into add_file_command and add_file.
5264 Make psymtab_to_symtab read in the string table if the file
5266 Two new parameters to read_dbx_symtab and start_psymtab.
5267 tm-sunos.h: New file.
5269 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5271 * infcmd.c: Change cont_command to continue_command and "cont"
5274 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5276 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
5278 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
5280 * values.c (USE_STRUCT_CONVENTION): Check for structures of
5281 size 1,2,4,8 rather than size < 8.
5283 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
5284 as necessary, not just once.
5286 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
5288 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5290 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
5292 * tm-news.h: Add CALL_DUMMY_*.
5294 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
5296 * config.gdb: In list_host, list_target, use ${i}, not $i.
5298 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5300 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
5302 * sparc-opcode.h: Change all store floating-point state register
5303 instructions to have the right match & lose fields.
5305 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5307 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
5309 config.gdb: If srcdir != ., create readline directory and
5310 copy a makefile into it.
5312 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
5313 consistency with POSIX.
5315 * breakpoint.c (bpstat_stop_status): Disable watchpoint
5316 when we exit its exp_valid_block.
5318 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
5320 * Makefile.dist: Bump version to 3.91.3.
5322 * Clean up handling of breakpoint commands (somewhat).
5323 Prompted by Tiemann bug report "cont 10" doesn't work any more.
5325 inferior.h: Add breakpoint_proceeded to inferior status struct
5326 and globals; save it and restore it.
5327 (clear_breakpoint_commands): Cleanup, remove old #define.
5329 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
5330 (save_inferior_status, restore_inferior_status): handle it also.
5331 (proceed): Remove earlier code that set breakpoint_proceeded.
5332 It is now set only in clear_proceed_status.
5333 (clear_proceed_status): Cleanup, use bpstat_clear rather
5334 than clear_breakpoint_commands. No callers need the stop_bpstat
5335 between clear_proceed_status and proceed.
5337 infcmd.c: Add breakpoint_proceeded definition and comment.
5338 (cont_command, jump_command, signal_command): Move call to
5339 clear_proceed_status right next to call to proceed.
5341 breakpoint.c (bpstat_do_actions): Avoid clobbering our
5342 caller's argument while running down the chain of breakpoints.
5343 Use new variable "breakpoint_proceeded" to determine when
5344 a command that it executes moves the inferior past the
5346 (bpstat_clear): Handle NULL argument.
5347 (bpstat_clear_actions): Avoid useless call to
5348 breakpoint_auto_delete.
5349 (delete_breakpoint): Clean up bpstat's that are pointing to
5350 the deleted breakpoint from the stop_bpstat chain.
5351 (breakpoint_auto_delete): Simplify.
5353 * Clean up handling of EOF, error on stdin, etc. This was
5354 prompted by a network problem that caused gdb to go into an
5355 infinite loop filling up its malloc'd memory.
5357 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
5358 not clear_breakpoints_commands, which is now gone.
5359 (main): If command_loop returns (e.g. from EOF on stdin), do
5360 a quit_command (looping back to command_loop if quit_command
5361 doesn't really quit).
5362 (command_loop): check result from command_line_input and
5363 exit if it returns NULL, rather than passing the NULL to
5365 (gdb_readline): Free malloc'd result space before returning
5368 * utils.c (query): Handle C-d to mean "yes", just as if the
5369 input was not a terminal. Also avoid infinite loop if EOF
5370 occurs in mid-input-line before newline. This allows
5371 query to be used at EOF on stdin with reasonable results.
5373 * infrun.c (proceed): Set breakpoint_proceeded.
5375 * values.c (value_as_long): Avoid infinite recursion for enums.
5376 (_initialize_values): Fix typo in help msg (kingdon).
5378 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
5379 RL_LIB for linking. This allows -lreadline for linking
5380 and nothing for dependencies, once readline is a real library.
5382 * config.gdb: Jim Kingdon: give useful error message if the
5383 host or target type is not recognized.
5385 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
5386 it just defines it. Dumb, but deal with it.
5388 * Jim Kingdon suggests:
5389 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
5391 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
5393 * Makefile.dist (VERSION): Bump version # to 3.91.2.
5395 * Clean up Bothner's changes.
5397 * blockframe.c (clear_pc_function_cache): New function.
5398 * blockframe.c: remake cache_pc_function_* static.
5399 * dbxread.c (symbol_file_command): remove references to
5400 cache_pc_function_* variables.
5401 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
5402 * printcmd.c: Avoid kludging a global variable (addressprint)
5403 to avoid printing the address of a string twice. Instead,
5404 pass the format letter 's' down low enough that it can be seen
5405 to avoid this problem.
5406 (print_formatted): Pass format arg to value_print.
5407 (restore_addressprint): Remove function.
5408 (do_examine): Avoid hacking addressprint, cleanups and such.
5409 (print_frame_args): Add a comment to a Bothner change.
5410 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
5411 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
5412 to wipe out the values cached in blockframe.c.
5413 * symtab.c (find_method): Add comment saying how big you must
5414 allocate to be "big enough". Per being terse again.
5415 * valprint.c (val_print): Handle format letter "s" to print
5416 strings without addresses. Add comment to vtbl printing code
5417 which casts with wild abandon. Rearrange reference-printing
5419 @0xaddr: value (print w/addressprint)
5420 value (print w/~addressprint)
5421 @0xaddr (parameter lists w/addressprint)
5422 or nothing (parameter lists w/o addressprint)
5424 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
5426 * Merge more changes from Per Bothner:
5428 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
5429 annoying) that I tried to improve it. Here are my suggestions.
5431 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
5434 Do automatic de-reference when taking the address of a reference.
5436 Don't deref_ref when printing parameter lists.
5438 More attempts at treating refernences properly.
5440 In val_print, if deref_ref==0, don't print dangling " = ".
5442 Add COERCE_REF macro, which de-references an REF.
5444 * Merge changes from Per Bothner:
5446 * Fixed (Sony news)-specific configuration problems.
5447 * Fixed other problems with using vanilla pcc and libc (enum problems;
5448 assumption that vsprintf exists).
5449 * Some major speed-ups (finc_pc_partial_function now caches a match;
5450 parsing avoids duplicate symbol_lookup calls).
5451 * Changed handling of baseclasses (no longer use baseclasses field
5452 of struct type, use the first n_baseclasses fields instead).
5453 * Various minor changes/fixes, most C++-related.
5456 Cache the most previous match from find_pc_partial_function.
5457 (Save both low and high ends of matching function's pc range.)
5458 This speeds up the loop of infrun.c:wait_for_inferior quite
5459 a bit, and makes step/next commands much zippier.
5461 Added an enum->int cast (otherwise, some compilers barf).
5463 No longer set baseclass offset to 0, since multiple
5464 inheritance now mostly works.
5465 Added a number of casts, to shut up compiler warnings
5466 (after stabs where made enums, not ints).
5467 When discarding a symbol table (in symbol_file_command),
5468 must clear the cache introduced in blockframe.c.
5469 Don't convert $vtbl_ptr_type to vtbl any more.
5470 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
5471 Mask off sign bit emitted by g++ for virtual table offset.
5472 Set voffset to -1 (not 1) for static member functions.
5474 Changed parsing/lexing of names to avoid doing symbol lookup twice
5475 (once when lexing to determine symbol class, once for real).
5476 Now only call symbol_lookup once. Fields of 'this' win especially big.
5478 Subpress printing addr twice in the case of 'x/s addr'.
5480 lookup_basetype_type is no longer used.
5481 Add find_methods as recursive helper function to decode_line_1.
5482 This allows multiple inheritance to work.
5483 Also, once one or more matches has been found, do not look in
5484 base-classes. (Baseclass methods would be overridden, anyway.)
5486 Removed baseclasses array in struct type.
5487 Instead of using baseclasses[i], use fields[i-1].
5488 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
5489 Changed sign convention of voffset (previous was inconsistent).
5491 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
5493 Used to assume existence of vsprintf. Re-written to not need it
5494 if HAVE_VPRINTF is undefined.
5496 typecmp was too pessimistic. Made it less so.
5498 Don't print space after address.
5499 If vtable points to a misc symbol (with 0 offset), print it,
5500 since that indicates the actual class of the object.
5501 Changed ype_print_derivation_info to use new inheritance
5502 scheme (without baseclasses vector).
5504 In value_primitive_field, fixed some bugs left over from previous set of fixes.
5505 Also, changes needed because TYPE_BASECLASSES were removed.
5507 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
5509 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
5512 If there is no path set, and the symbols don't indicate what directory
5513 a file was compiled in, look in the current directory. But either
5514 a path or a known compilation directory will prevent this.
5517 Three independent bug fixes:
5518 * Remove the #if 0 block that breaks some stuff.
5519 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
5520 adapt gdb to either SunOS 4.0.* or 4.1.
5521 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
5524 Instantiate the class T when looking for methods in it. (Tiemann@sun)
5527 (type_print) Demangle the name being printed.
5528 (type_print_base) Handle botched demangling without coredump (tiemann).
5531 (check_stub_method): Document routine.
5532 (tiemann) fix bug for no-arg functions
5533 Avoid clobbering beyond end of malloc'd storage.
5534 Terminate the argument list properly.
5536 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
5538 * Changes merged by John Gilmore:
5541 In breakpoint_1, use new print_address_symbolic instead
5542 of find_pc_partial_function. (This forces use of assembler-level
5543 addresses, and avoids misleading non-mangled source-level names.)
5545 Generalize ansi argument such that -1 means skip arglist totally.
5546 Removed global variable print_ansi_qualifiers (which made
5547 code non-reentrant), in favor of extra explicit arguments
5548 to internal routines.
5550 Add new helper function print_address_symbolic.
5551 Use find_pc_misc_function instead of find_pc_partial_function
5552 (since we want assembler-level symbols here).
5554 Print unknown function as just "f (...)", not "f (...) (...)".
5555 Use new fputs_demangled explicitly.
5557 Fixed a typing violation (problem: value.h cannot be imported
5558 without renaming many variable in this file).
5559 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
5560 decode_line_1: Moved forward some never-reached code.
5561 Made decode_line_2 skip function prologues correctly.
5563 fputs_filtered should not demangle by default.
5564 Add new fputs_demangled to demangle on demand..
5566 Change value_struct_elt to use value_primitive_field (using recursive
5567 utility function search_struct_field). This allows foo.bar to work
5568 for multiple inheritance (so far only for data fields).
5569 Change check_field in the same way (recursive helper function
5570 to support multiple inheritance).
5571 (Note: there are more of these problems that I haven't fixed.
5572 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
5573 value_of_this: 'this' symbol name is now just "this", note "$this".
5575 Don't print static members.
5576 Avoid printing "members of <type>" if there are none.
5577 Simplified type_print_derivation_info by merging duplicate code.
5578 Remove useless blank lines in type_print_base (ptype command).
5580 Added declaration of new routine value_primitive_field.
5582 Added value_primitive_field which is generalized version of
5583 value_field that can handle multiple inheritance (non-zero offsets etc).
5584 Re-implemented value_field to call value_primitive_field.
5586 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
5588 * infcmd.c -- insert else to avoid 'delete env' coredump when you
5589 delete the whole environment. Karl Berry reported the bug.
5590 * source.c - fix openp to avoid //'s in filenames, which
5591 trigger an Emacs bug causing it to not be able to find files
5592 when running gdb in a window.
5593 * dbxread.c - zap the #if 0 that botches the add-file code.
5594 It seems to work a lot better without all the code commented out.

5604 added remote-sa.sparc.c
5605 * added remote.sa-sparc.c, a modification of remote.c
5606 which conducts a dialog directly with the SparcStation prom.
5607 * breakpoint.c, infrun.c, sparcdep.c added
5608 remote_insert_breakpoint(), and remote_remove_breakpoint()
5609 to breakpoint.c instead of directly writing breakpoint instructions.
5610 * sparcdep.c on remote_debugging,there is no need
5611 to remove signle step breakpoint instructions.
5612 * main.c added "-epoch" flag and "int epoch_interface" to main.c
5614 * printcmd.c - epoch interface sends lisp expressions to open up
5615 epoch windows on inspection.
5616 * valprint.c - added arrayprint, and addressprint and made adding
5617 format controls easier
5618 * wait.h added a couple of undef's because we were getting

5689 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
5690 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME

5715 step_resume_break_address != NULL, even if another_trap.
5716 If trap_expected and we enter sigtramp, then set up a
