1 Fri Oct 4 22:30:06 1991 John Gilmore (gnu at cygnus.com)
3 * configure.in, tm-i386v.h, xm-i386v.h: Intel 386 Mach host port.
4 * xm-i386mach.h, mach386-xdep.c, xconfig/i386mach: New files.
6 Fri Oct 4 17:04:31 1991 Per Bothner (bothner at cygnus.com)
8 More patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
9 * mips-xdep.c (store_inferior_registers): Don't try to
10 write the (pseudo) FP.
11 * mipsread.c (parse_partial_symbols): Improved algorithm for
12 setting pst->texthigh.
14 Fri Oct 4 16:47:32 1991 Roland H. Pesch (pesch at cygnus.com)
16 * doc/Makefile: make TEXINPUTS include . everywhere
18 Fri Oct 4 00:35:56 1991 John Gilmore (gnu at cygnus.com)
20 * coffread.c, dbxread.c, symfile.c, symmisc.c, symtab.h: Remove
21 vestiges of typevectors, which were for symsegs and are no longer
22 used. (From a question by Eliot Dresselhaus
23 <dresselh@RFT30.nas.nasa.gov>).
25 Thu Oct 3 09:33:26 1991 John Gilmore (gnu at cygnus.com)
27 * dbxread.c, coffread.c: static-ize functions that were
28 gratuitiously external. (From Fred Fish.)
30 * c-exp.y: sym->class to SYMBOL_CLASS (sym).
32 * dbxread.c (dbx_lookup_type): Keep doubling size of typevector
33 until it is large enough.
35 * dbxread.c (read_type): Handle error case slightly better.
36 Make complaint message not C++-specific.
38 Wed Oct 2 17:21:07 1991 Stu Grossman (grossman at cygnus.com)
40 * infrun.c (wait_for_inferior): Fix step/next so that you only
41 stop at the beginning of a new line. This fixes various problems
42 with for loops, nested if-else's and switch statements.
44 Tue Oct 1 06:33:55 1991 John Gilmore (gnu at cygnus.com)
46 * symtab.c (lookup_symtab_1, lookup_symbol): "fatal" errors
47 between symtabs and psymtabs become ordinary error()s.
49 * dbxread.c (read_dbx_symtab): Relocate end_of_text_addr
50 properly, making "end pc" correct in shared lib psymtabs.
51 (From Guy Harris <guy@auspex.com>.)
53 Mon Sep 30 13:15:31 1991 John Gilmore (gnu at cygnus.com)
55 * dbxread.c: Enable, but soften, const_vol_complaint.
56 (read_dbx_symtab): N_STSYM and N_LCSYM define static vars.
57 Ditto Gould N_NBSTS and N_NBLCS. Also, all types in the psymtab
58 should be file-scope, not global.
59 (read_struct_type): Remove ancient multiple-inheritance warning.
60 (read_range_type): Check base type, complain & patch if undefined.
61 * stack.c (frame_info): Demangle the function name in `info stack'.
64 Sat Sep 28 10:02:33 1991 John Gilmore (gnu at cygnus.com)
66 * eval.c (evaluate_subexp_for_address): Don't use
67 TYPE_POINTER_TYPE directly (it might be zero if this type has
68 never had a pointer created before); use lookup_pointer_type.
69 * symtab.c (lookup_method_type): Arguments were swapped in all
70 callers, so fix it here. I'm amazed this worked at all!
72 Fri Sep 27 18:09:31 1991 John Gilmore (gnu at cygnus.com)
74 * c-exp.y, m2-exp.y: Define more yysymbols that happen to be
75 "bss" rather than "data" symbols, but which still conflict.
78 * coffread.c (coff_symfile_read): Use xmalloc, not malloc.
79 * core.c (core_files_info): Shorten output.
80 * exec.c (exec_files_info): Ditto.
81 (build_section_table): Ignore zero-length sections.
82 * language.c, printcmd.c: Lint.
83 * language.h (get_frame_language): Declare.
84 * saber.suppress: update.
85 * stack.c (find_relative_frame): Remove complex code that was
86 #if 0'd, stick with simple code. Lint.
87 * saber.suppress: Update a bit.
88 * symfile.c (add_symbol_file_command): Add "?" to question.
89 * utils.c (parse_escape): Avoid \a due to bdead compilers.
90 * value.h: Declare typedef_print.
92 * valprint.c (val_print, type_print_base): TYPE_CODE_RANGE less
95 * nindy-tdep.c (nindy_frame_chain_valid): Use lookup_misc_func.
96 (Reported by Mark Peek <mark@imagen.com>.)
98 * solib.c (solib_map_sections): Relocate all sections, even
99 though only the text section's size is tracked. Mark ld_text
100 for eventual elimination as we generalize to N sections.
102 * infrun.c (wait_for_inferior): Don't check if the PC is in a
103 call_dummy if we were stopped by a random signal that is being
104 passed to the program. This produced wierd results when calling
105 functions in the inferior and signals (e.g. SIGALRM) were in use.
107 Tue Sep 24 18:05:30 1991 John Gilmore (gnu at cygnus.com)
109 * infrun.c (IN_SIGTRAMP): Not parenthesized properly.
110 Bugfix from Paul Eggert <eggert@twinsun.com>.
111 * tm-ultra3.h (IN_SIGTRAMP): Ditto.
112 * valprint.c (print_floating): Print 9 digits for IEEE floats.

127 and restore the language string after giving help.
128 * valprint.c (typedef_print): Print typedef in C or M2.
129 * symtab.c (list_symbols): Use it.
130 * main.c (main): Avoid any output before (gdb) prompt when -q.
131 * language.c (set_language_command): Handle errors by restoring
132 the language string to its current state (fix from A. Beers).
133 * doc/gdbint.texinfo: Roll in information from README. Rearrange
134 "how to install" and "how to print the doc" stuff so it drops
136 * configure.in: Rename rtpc CPU to romp to match config.sub.
137 * README, WHATS.NEW, TODO: Update for gdb-4.1.
139 Fri Sep 20 17:39:14 1991 Roland H. Pesch (pesch at cygnus.com)
141 * doc/gdb.texinfo: Updates from ChangeLog. set/show write,
142 autoloading shared libs, copyright etc on GDB startup, clean up $_
143 and $__ index refs, set/show listsize and related updates to list
144 cmd. New host/target configs.
146 Fri Sep 20 15:46:00 1991 Roland H. Pesch (pesch at cygnus.com)
148 * doc/Makefile: generate aux version-no file doc/gdbVN.m4
149 from main Makefile.in version definition
150 doc/gdb.texinfo: use version recorded in doc/gdbVN.m4 for current
152 Makefile.in (setup-to-dist): generate doc/gdbVN.m4
154 * doc/gdb.texinfo: merge new language-switching and lang-specific
157 Fri Sep 20 15:00:57 1991 Per Bothner (bothner at cygnus.com)
159 * mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
160 compilers (which may lack stddef.h).
162 Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com)
164 * dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and
165 N_WARNING are the same except for the N_EXT bit, so just use their
166 values alone, rather than OR-ing them with N_EXT.
168 Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com)
170 * mipsread.c (parse_lines): Deal with negative extended line
173 * c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid
174 global symbol conflicts.
176 Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
178 * .gdbinit: Move 'set complaints' to top, so it runs even in
179 case we aren't debugging GDB.
180 * language.c (_initialize_language): Fix type check and range
181 check documentation strings.
182 * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
183 language.c can use it. (Though language.c should really not be
184 handling warnings/errors the way it does, FIXME.)
185 * symtab.c (lookup_primitive_type): const lint.
187 Bugfix from Peter Schauer:
188 * source.c (lines_to_list): Make signed, to avoid comparison
189 going unsigned and complaining that -3 is too high for 21 lines.
190 * stack.c (lines_to_list): Ditto.
192 Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
194 * Makefile.in (HFILES): Add minimon.h.
195 (VERSION): Roll version number to 4.0.95.
196 (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
197 New rules for building distributions. Normal distribution
198 is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
199 one level up from here; it calls make-proto-gdb.dir to build a
200 directory `proto-gdb' which is an image of the release. The old
201 `gdb.tar.Z' rule still works too.
202 * config.sub, configure: Roll in latest from ..
204 Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
206 * doc/gdbint.texinfo: Reorder contents; reorganize new-host,
207 new-target, and new-config chapters; fix minor typos; come closer
208 to usual GNU markup conventions for @file @samp @code @var.
210 Thu Sep 19 17:04:12 1991 Per Bothner (bothner at cygnus.com)
212 Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
213 * mipsread.c (parse_partial_symbols): Enter the name of all
214 structs/unions... into the psymtab so we can access them if the
215 symtab is not read in.
216 * mips-tdep.c: Remove some unneeded #includes.
217 * xconfig/dec3100: Add HAVE_STRSTR.
219 Thu Sep 19 15:14:23 1991 John Gilmore (gnu at cygnus.com)
221 * Makefile.in: Circumvent Sun Make bug on *-exp.tab.o.
222 * c-exp.y, m2-exp.y: Lint.
223 * m2-exp.y: Avoid using yytname[] which is a Bison-ism.
224 * valprint.c (val_print_fields): Check for stub type.
225 * mipsread.c (_initialize_mipsread): Avoid using
226 builtin_type_void at initialize time.
227 (mipscoff_symfile_read): use it now.
229 Wed Sep 18 15:55:51 1991 John Gilmore (gnu at cygnus.com)
231 Merge multiple-language support, and partial Modula-2 support,
232 from Andrew Beers <beers@cs.buffalo.edu>.
234 * i387-tdep.c: New file, consolidates most 80387 support,

252 #if 0 out its uses, though, since they set a dead value.
253 * coffread.c (end_symtab): Use allocate_symtab.
254 (process_coff_symbol): #if 0'd for functions and params as above.
255 (read_enum_type): Recognize Modula-2 BOOLEAN.
256 * symtab.c (add_param_to_type): #if 0'd function to add a

328 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
330 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
331 entries are enclosed herein. Not all of these changes
332 have been merged into the master GDB sources -- check the
333 ChangeLog above here for the merge log.
335 Mon Jun 3 17:05:45 EDT 1991
337 m2-exp.y Created. Tested outside of GDB for a few days. Proper
338 operators were added, C specific operators and tokens
339 removed. yylex() revamped to some extent. Still things
340 missing from the grammar, such as sets.
341 Tested for two weeks in GDB v3.5.
343 Tue Jun 11 17:23:48 EDT 1991
345 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
346 so they are built-in. Sort of a hack.
348 Fri Jun 14 12:53:51 EDT 1991
350 m2-exp.y Added range checking for numeric constants. Any numeric
351 constant is assumed to be of builtin type INTEGER unless:
352 (1) it is octal or hexadecimal, in which case it is a
353 CARDINAL; (2) it is too big to fit into an INTEGER, in
354 which case it is a CARDINAL.
355 eval.c Added simple range checking for +, -, and * on integers.
356 Doesn't work very well for *, since 6 * 1,000,000,000 =
357 1,705,032,704, which fails the simple test of result >=
358 first_operand, no matter in what order the operands are.
360 Tue Jun 18 14:11:30 EDT 1991
362 Broke the parser into parts, one containing the C grammar and the other
363 containing code to be shared by all of the grammars.
365 The following files no longer exist:
370 The following files were added:
372 c-exp.y (The C grammar)
373 m2-exp.y (The Modula-2 grammar)
374 parser-code.c (Code that is shared by the above grammar)
378 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
379 now necessary to use the Bison compiler compiler, since it
380 will generate function/variable prefixes other than yy.
382 Tue Jun 18 16:47:49 EDT 1991
384 symtab.[ch] Added the external variable working_lang, than holds the
385 value of the current working language.
386 Added the ennumerated type language_mode, with the values
387 language_auto and language_manual, the former meaning that
388 GDB sets working_lang as needed, and the latter meaning
389 that the value of working_lang is totally under user
391 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
392 REAL, BOOLEAN and CHAR. Also added the type codes
393 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
394 utils.c Added set_language_command and show_language_command to
395 implement the GDB support commands "set language" and
397 expression.h A number of identifiers were added to the type exp_opcode
398 to facilitate Modula-2 builtin functions, integer
399 division, and array indexing.
401 Wed Jun 19 13:25:58 EDT 1991
403 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
404 if the language specified by working_lang requires the use
405 of strict typing of expressions. Eventually, even this
406 will be able to be changed by the user.
407 Added the macro RANGE_CHECK, which evaluates to non-zero
408 if the language specified by working_lang requires the
409 checking of a value against the domain of its type.
410 Eventually, even this will be able to be changed by the
412 language.[ch] Predicates involving types (simple_type, ordered_type,
413 same_type, integral_type, numeric_type, character_type,
414 boolean_type, float_type) are added. These predicates are
415 based on the current value of working_lang, and are handy
418 Wed Jun 19 15:39:34 EDT 1991
420 eval.c Added the function type_array_rank which computes the rank
422 valarith.c Added the funtion value_bool, which when given a integer
423 value.h value (ie. struct value *) as an argument, it returns a
424 boolean value (ie. struct value *) true if that integer
425 is non-zero, and a boolean value false otherwise.
426 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
427 will print out properly.
429 Wed Jun 19 16:36:34 EDT 1991
431 valops.c Added the function value_capitalize, which returns it
432 value.h argument capitalized if its argument is a lowercase
433 letter, or the argument unchanged if its argument is not a
435 valarith.c Added the function range_check_p, which returns non-zero
436 value.h if its value argument is between the integral bounds upper
438 Added the function range_check_enum_p, which makes sure
439 that its value argument is a valid member of the domain of
441 Added the function range_check_range_p, which makes sure
442 its value argument lies between the upper and lower bounds
443 of its type argument, which must be a ranged type.
444 Added the function check_array_index, which range and type
445 checks an index of an array.
446 Added the function value_multi_subscript, which computes
447 array[idx1,idx2...idxN], given a value array and an array
448 of values representing indicies.
449 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
450 unpack_long to work with TYPE_CODE_BOOL and
453 Wed Jun 19 18:04:08 EDT 1991
455 symtab.c Stored pervasive types in a structure and make
456 lookup_pervasive_type() a lookup function that was based
457 on working_lang. If lookup_pervasive_type() returned
458 non-zero, then that value was returned (a fix, since
459 before it simply wouldn't return the pervasive type.)
460 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
461 non-zero if the language specified by working_lang means
462 "conversion" when it says "cast".
463 valops.c Added the function value_real_cast(), which performs a
464 value.h *cast*, not a *conversion*, which is what value_cast()
465 does when it can. In particular,
466 value_cast(<float_type>,4) = 4.0, while
467 value_real_cast(<float_type>,4) = some mess.
468 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
469 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
470 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
471 and MIN on integral types. *NOTE*: These are currently
472 hardcoded to work only if there are 8 bits per storage
474 eval.c Made logical functions call value_bool to return a
475 properly typed boolean value, based on working_lang.
477 Thu Jun 20 11:55:27 EDT 1991
479 valprint.c Types now print out in a Modula-2 fashion. This works for
480 the cases when the type is printed out step-by-step, that
481 is, it doesn't work when the name of a structured type
482 (which includes the keyword "struct", etc.) is simply
484 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
485 since type specifications in C and Modula-2 are very
486 different. The C printing of a type is very recursive,
487 whereas in Modula-2 it is generally very simple. C has
488 type prefixes and suffixes, which have no real analogue in
489 Modula-2. Maybe type_print() should call a language
490 specific type printer. This is also advantageous if we
491 compile GDB to exclude some of the languages. We'll just
492 leave those functions out.
494 Thu Jun 20 16:57:10 EDT 1991
496 dbxread.c When reading the complete symbol table in (via
497 psymtab_to_symtab()), the number and types of function
498 arguments are added to a function type. define_symbol()
499 calls add_param_to_type() to accomplish this.
500 Assumption: when we come across a function definition
501 (N_FUN symbol with an 'f' or 'F' in the name), its
502 arguments will appear before another function definition.
503 When a function is found, a pointer to its type is placed
504 in the global in_function_type. Changes that
505 add_param_to_type() makes are to this global.
506 valprint.c The type of a function now includes (for Modula-2) the
507 types of its parameters.
508 eval.c Type checking and a check for the proper number of
509 arguments is now done for function calls. Not sure of the
510 impact this has on C++ member function yet.
512 Thu Jun 20 19:58:48 EDT 1991
514 valprint.c Rewrote the type printer. Broke it into two language
515 specific parts, adding the functions type_print_m2() and
517 An unfortunate consequence is this: if you debugging a C
518 program in Modula-2 mode (why?), info types does not work
519 well with regular expressions, since the types are printed
520 out in Modula-2 terminology, but stored in C terminology.
521 language.[ch] Added the functions new_type_last(), type_keyword(), and
522 type_sep() to aid in the printing of typedefs.
523 symtab.c Made the printing of typedefs as language independent as
524 possible through calls to new_type_last(), type_keyword(),
527 Fri Jun 21 11:50:26 EDT 1991
529 dbxread.c Check all incoming ennumerated types. If it looks like
530 Modula-2's BOOLEAN type, then change the type_code of the
531 type to TYPE_CODE_BOOL so we can process it as a boolean
533 valprint.c Replaced some of the 0x%x with calls to sprintf and
534 hexformat() in val_print().
535 language.[ch] Added the function hex_to_string(), which converts its
536 integral argument to a hexadecimal number (format is
537 language based) and returns the result as a string.
539 Mon Jun 24 12:25:07 EDT 1991
541 valprint.c Some functions call type_print_1() directly, instead of
542 value.h using type_print(), so they can specify where (column) to
543 print things. Since type_print() takes care of language
544 dependence, that needs to be called first. Added a
545 parameter depth to type_print() (so it is now like
546 type_print_1). Changed type_print to type_print_at, and
547 made type_print a macro that passes a depth argument of
549 symmisc.c Changed all calls to type_print_1 to calls to
551 Makefile.dist Made it possible to build GDB for a specific set of
552 depend languages. Do this by passing a definition for the macro
553 LANGS to make. LANGS should be a string containing a
554 space-separated list of language names (ie. LANGS="c m2").
555 The default is to build all languages. Note that grammar
556 files must follow the naming convention of <lang>-exp.y.
557 gdb.lang This holds the current value of the LANGS macro. It is
558 examined every time make is called, and is updated if
560 eval.c Added #ifdef _LANG_<lang> to these files.
561 expread.c Still need to add them to dbxread.c and coffread.c.
569 Mon Jun 24 16:33:11 EDT 1991
571 language.[ch] Added the functions hexformat_pre() and
572 hex_to_string_pre(), which take a prefix argument to
573 include in the format string. Thus, hexformat_pre("08") will
574 return "0x08x" (if the working language is language_c).
575 Made hexformat() and hex_to_string() calls to the above
576 with "" as the prefix argument.
578 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
579 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
580 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
581 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
582 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
583 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
584 valprint.c, vax-pinsn.c
586 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
587 calls to hexformat() and hex_to_string(). Format strings without
588 the leading "0x" were ignored.
590 depend Updated to take the above into account.
593 Tue Jun 25 15:27:18 EDT 1991
595 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
596 and type_check_t to keep track of the current state of
597 range and type checking.
598 main.c Added the variables range_mode, range_check, type_mode,
599 and type_check to record the current state of range and
600 type checking. Added initialization code to main().
601 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
605 Tue Jun 25 17:57:08 EDT 1991
607 dbxread.c process_one_symbol() updates the variable (enum language)
608 source_lang based on the extension of the filename
609 contained in the N_SO sybmol that started this symtab.
610 When end_symtab() is called, the value of source_lang is
611 put into the language field.
612 stack.c select_frame() sets working_lang (and possibly type_check
613 and range_check) to the language field of the symtab
614 associated with the frame that is selected if working_mode
615 is language_auto. If working_mode is language_manual, a
616 warning is printed and working_lang is not set.
617 language.c Added the function set_type_range(), which sets the value of
618 type_check and range_check (if their modes call for
619 automatic setting) based on the current value of
620 working_lang. A non-zero argument will cause the current
621 settings to be output.
624 Wed Jun 26 14:51:40 EDT 1991
626 eval.c Added range checks on assignment.
627 m2-exp.y Added the grammar for sets to the language. Currently,
628 these do not do anything except print an error message.
630 Wed Jun 26 17:01:04 EDT 1991
632 m2-exp.y Added the ability for parse_number() to parse negative
633 numbers. A global flag is set upon encountering a unary
634 minus. This was done to make, for example, 1 parse as a
635 CARDINAL, and not as an integer, per Wirth's examples in
636 Programming in Modula-2 ed.4.
637 valprint.c Added support for "set radix 2" by then setting
638 output_format to 't'.
639 eval.c Implemented range checking on subrange types. Added calls
640 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
641 Implemented MIN and MAX for ennumerated types. The
642 minimum value of an ennumerated type is defined by Wirth
643 as the first identifier, and the maximum as the last.
644 m2-exp.y Made octal numbers ending with "B" be characters and those
645 ending with "C" be numbers, per Wirth's book. (p. 34)
647 Thu Jun 27 14:11:52 EDT 1991
649 stack.c select_frame() now only sets working_lang, it does not
650 notify the user. If working_mode is language_manual, then
651 a warning is issued once.
652 main.c At the end of each call to execute_command(), working_lang
653 is checked against the local static (enum language)
654 current. If they differ and working_mode is
655 language_auto, the new settings of language, type and
656 range checking are printed out.
657 stack.c Modified frame_info() to include the language of the
658 current frame in the output of "info frame".
659 language.[ch] Added the function language_str() which returns the name
660 of the current language.
662 Fri Jun 28 15:33:14 EDT 1991
664 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
665 the language. INCL and DECL currently cause an error,
666 since sets are not implemented yet. INC and DEC are
667 implemented as PREINCREMENT/PREDECREMENT with one
668 argument, and as ASSIGN_MODIFY with two arguments.
669 eval.c Added type checking to the above cases.
670 value.h Added not_lval_constant to the lval_type ennumerated type.
671 not_lval_constant means that the value is a constant
672 value; that is 3 or 'a' or TRUE, not as in a constant
673 identifier. This is used to help coerce numbers such as 3
674 to either signed or unsigned numbers.
675 valops.c Added the function value_coerce_constants() which coerces
676 constant integers as following: if one is a constant and
677 the other is not, the constant's type is set to the type
678 of the other argument. If both are constants and one is
679 signed, the other is converted to a signed constant.
681 Sat Jun 29 17:26:29 EDT 1991
683 valarith.c Added a better range checker. It now checks range
684 (successfully) on integral operations [+-] (signed and
685 unsigned) for any C sized type. Still does not work well
687 int_in_size() returns an integer that is coerced to fit into
688 specified number of bytes.
690 Mon Jul 1 13:04:14 EDT 1991
692 language.[ch] Added the function binop_result_type(), which returns the
693 builtin (struct type *) type that would be the result of a
694 binop on the two values V1 and V2.
696 Wed Jul 3 19:22:53 EDT 1991
698 source.c Extended source_info() to include the source language in
699 the output from "info source".
701 Fri Jul 5 13:48:52 EDT 1991
703 utils.c Moved the support functions for the GDB set/show commands
704 dealing with language into language.c.
705 language.c Added the function language_info(), which displays info
706 about the current working language, type and range check
707 settings. Called via the GDB command "info language".
708 Added an initialization routine _initialize_language(),
709 that sets defaults for the language, type and range
710 variables and sets up the new GDB commands.
711 main.c Language setup moved to language.c.
714 Mon Jul 8 10:10:22 EDT 1991
716 valarith.c Debugged the range checker for arithmetic. Still does not
717 work for multiplication very well.
719 Mon Jul 8 12:40:37 EDT 1991
721 language.[ch] Added the function value_true() which returns non-zero if
722 its argument represents a boolean true value.
723 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
724 check the truth of an expression.
726 Thu Jul 11 12:51:34 EDT 1991
728 language.[ch] Added the predicate structured_type(), which returns
729 non-zero if the argument is a structured type.
730 Added the predicate pointer_type(), which returns non-zero
731 if the argument is a pointer type.
732 eval.c Added the ability to do addition and substraction on
733 pointers and integers. This case simply bypasses the
736 Thu Jul 11 14:41:42 EDT 1991
739 Added the symbol N_DEFD (0x4a) which is a definition
740 module dependency that is used by the GNU Modula-2
741 compiler and the linker. It is not important to GDB,
742 except that [dbx|coff|mips]read.c should ignore these
745 Fri Jul 12 16:07:00 EDT 1991
747 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
748 0 in val_print(). Also added statements to the else part
749 to coerce type (argument to val_print) to a pointer type
750 if it is an "array of unspecified length".
751 valops.c Added the function value_m2_string(), which returns a
752 (value) value which is a constant string, whose type is
753 (ARRAY [0..n] OF CHAR). The length field of the type
754 structure is set to zero, so it will be interpreted as an
755 "array of unspecified length".
756 stack.c Moved the language/frame mismatch check to
757 main.c:execute_command().
758 main.c The working language is recorded each time
759 execute_command() is executed. If working lang has
760 changed during its execution, then the new
761 language/type/range info is printed out for the user. If
762 the working language does not match the language of the
763 frame, a warning is issued.
765 Sat Jul 13 16:16:39 EDT 1991
767 eval.c Moved all the type-checking stuff for operators to
768 language.[ch] language.c. This is so we can keep language-specific
769 stuff (like for what type operators are defined) in
771 language.[ch] Added the function binop_type_check(), which checks to see
772 if its two (value) arguments are type-compatible with its
773 opcode argument. The opcode should represent an operation
774 involving an operator. Also added the macro function
775 unop_type_check, which calls binop_type_check with a
776 NULL second argument.
777 expprint.c Added Modula-2 operators to the op_print_tab, so info
778 expression.h break works correctly. Also added "op_string", which
779 returns the string corresponding to the (enum exp_opcode)
780 opcode that is its argument.
783 Sat Jul 13 18:26:18 EDT 1991
785 coffread.c Added code to record the type of function arguments with
786 each paricular function. Code is very similar to that
788 dbxread.c Moved add_param_to_type() to symtab.c
789 symtab.[ch] Added function add_param_to_type() from dbxread.c
791 *** NOTE: The above additions have not been tested.
793 Mon Jul 15 12:50:47 EDT 1991
795 langauge.[ch] Added the functions type_error and range_error, which work
796 like error() except if the type/range mode is set to
797 *_mode_warn, then they do not do a return_to_top_level(),
798 but merely print a warning.
799 Also changed [set|show]_[type|range]_command() to support
800 the new "warn" feature.
802 Thu Jul 18 17:50:54 EDT 1991
804 mipsread.c Added code to record the type of function arguments with
805 each particular function. Code is very similar to that
808 *** NOTE: The above additions have not been tested.
810 Fri Jul 19 11:19:10 EDT 1991
812 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
813 UMIN_OF_SIZE, which when given a size of a numeric type,
814 return the maximum and minimum value it can hold. UMAX...
815 and UMIN... return the result for unsigned types.
816 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
817 struct types. They call above macros.
818 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
819 avoid a name conlict with the above.
820 c-exp.y Added range checking on numeric constants in
821 parse_number() for completeness.
822 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
823 return 0 if working_lang is not language_c.
825 Thu Aug 8 14:17:22 EDT 1991
829 breakpoint.c Documentation strings of some commands changed to
830 eliminate the references to the C language where
833 Tue Aug 13 15:48:03 EDT 1991
835 m2-exp.y Added qualified identifiers to the grammar. The semantics
836 are slightly different from those of the GDB operator ::
838 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
839 type_exp, where type_exp is any valid type expression.
841 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
842 printcmd.c Modified ptype_command() so it actually parses the input
843 (necessary for type expressions with scope qualifiers).
844 Added the function ptype_eval() which expects an
845 expression composed of one OP_TYPE element.
846 *.[ch] Replaced all occurences of parse_c_expression with
848 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
850 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
852 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
854 Small fixes from Peter Schauer:
856 * infrun.c (child_attach): Lint.
857 * solib.c (find_solib): Handle shared libs version 2.
859 Small fixes from David Wood:
861 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
865 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
866 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
868 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
869 chars_per_line is at maximum (user typed `set width 0'). Fix
870 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
872 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
874 * coredep.c: include ptrace.h where necessary.
875 * mipsread.c(parse_lines): fix unsigned char problem that was
876 messing up line numbers on SGI's and possibly other MIPS based
878 * infrun.c (child_create_inferior): use better test to check
879 return val from setpgrp().
880 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
881 for sgi/irix support.
883 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
885 * mipsread.c (parse_symbol): Put non-static procedures
888 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
890 Patch together `text_start' and `text_end' for 29K port.
892 * exec.c (exec_command): If NEED_TEXT_START_END, define the
893 variables and set them based on the exec file.
894 * am29k-tdep.c: declare text_start.
895 * valops.c (call_function_by_hand): declare text_end.
897 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
898 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
899 because machines that do this will also have to know to
900 set NEED_TEXT_START_END. Besides, it was a redundant way to
902 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
903 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
906 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
908 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
910 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
911 Pass MUNCH_DEFINE to munch whenever we run it.
912 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
913 format string; use 0x%x instead.
914 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
915 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
916 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
917 * inflow.c: Handle `short' process group IDs.
918 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
919 and check for ptrace errors.
920 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
921 (coff_symfile_init): Initialize text_bfd_scnum.
922 (read_coff_symtab): Use it to find the text [and absolute?] sections.
923 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
924 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
925 Merge target arm case with other "easy" cases. Add target
926 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
927 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
929 * minimon.h, remote-adapt.c, remote-mm.c: Add.
930 * munch: Cope with RT/PC putting fns in data segment.
931 Restore ability to override `nm' by specifying MUNCH_NM.
932 * xconfig/rtbsd, xconfig/ultra3: New host systems.
933 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
934 and remote-adapt. Remove encapsulated coff #define's (the
935 support should go in BFD, and gdb shouldn't know or care).
936 * tconfig/a29k-kern: Same, but for remote kernel debugging.
937 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
938 * tm-29k.h: Update BADMAG (though it should go away).
939 Allow the register definitions to be overridden in another
940 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
941 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
942 DUMMY_SAVE_GR96, for handling kernel calling conventions
943 that use GR64+ rather than GR96+.
944 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
945 remote debugging of Ultra3 kernel. Includes tm-29k.h and
946 overrides various things.
948 * remote-mm.c (mm_attach, mm_wait): Handle attach like
949 child_attach does, making a clean stop in the newly attached
953 * coffread.c: Make coffread independent of any particular
954 variant of COFF. Avoid #include-ing any particular one except
955 internalcoff.h. BFD now passes key values for symbol reading
956 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
957 and the symbol masks and shifts); use them.
958 Remove obsolete end_of_text_addr.
960 * exec.c: Remove unused include files.
962 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
964 * Makefile.in (documentation targets): Pass $(M4).
965 Bugfix from eggert@twinsun.com (Paul Eggert).
967 * stack.c (down_silently_command): Check for stack existence.
969 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
971 * Makefile.in (VERSION): Update to 4.0.3.
973 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
975 * core.c (core_file_command): Print frame at coredump with
976 its level number, by calling print_stack_frame.
977 * frame.h: Add selected_frame_level, print_stack_frame.
978 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
979 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
980 Change print_sel_frame and print_selected_frame callers to
983 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
984 * symfile.c (free_named_symtabs): Ditto.
985 * main.c (main): wrap_here needs an arg.
986 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
987 (solib_add): Avoid noise.
988 (solib_create_inferior_hook): Lint.
989 (sharedlibrary_command): Move dont_repeat to here.
990 * utils.c (error): Call wrap_here to force buffered output.
992 Small patches from Peter Schauer:
994 * coffread.c (start_symtab): Free any existing line_vector before
996 (read_coff_symtab): Ditto for type_vector.
998 * source.c (lines_to_list): New variable, replacing function.
999 (all uses): Use as variable.
1000 (_initialize_source): Add 'set listsize' and 'show listsize'.
1001 * utils.c (lines_to_list): Remove function.
1002 * stack.c (print_frame_info): Use as variable.
1003 * defs.h (lines_to_list): Remove declaration.
1005 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1007 * breakpoint.c (insert_breakpoints): Restore warning about
1008 the program might be running in another process, but only for
1009 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
1010 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
1012 * utils.c (error): if error_pre_print is set, print the string
1014 * main.c (main, print_gnu_advertisement, print_gdb_version):
1015 Reformat legalese so it always prints, but acts as an "I'm here"
1016 message while symbols are being read. If any errors occur,
1017 print a few newlines to set off the message and start it at the
1018 left margin. Remove mention of "help" command, and don't yak
1019 about symbol reading.
1020 (catch_errors): Error string is now printed first in case of
1022 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
1023 suggest the "help" command.
1025 * Makefile.in (VERSION): Set to 4.0.2.
1027 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
1029 * .gdbinit: Remove useless "rr" command. Set complaints
1030 to 1 for people debugging gdb.
1032 * breakpoint.c, remote-vx.c: Reword strings printed by
1033 catch_errors callers.
1035 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
1037 * WHATS.NEW: "history write -> history save". Doc "write on/off".
1038 (Fix from kenc@viewlogic.com.)
1040 Fix some infrastructure to be able to cope with host and target
1041 machines with different sized basic types (ints, ptrs, etc).
1042 (Idea from pierre@la.tce.com (Pierre Willard).)
1044 * values.c (value_from_longest): Rename from value_from_long.
1045 Handle pointer types as well as integers, so that targets with
1046 different pointer sizes from the host can be accomodated.
1047 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
1048 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
1049 uses of value_from_long to value_from_longest.
1050 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
1051 the correct pointer type to value_from_long{est}.
1053 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
1055 * remote-vx.c: Remove obsolete code for calling functions via
1056 vxworks kludge interface (it referenced value_from_long).
1058 * valops.c (value_string): Find malloc with lookup_misc_func, not
1061 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1063 Make writing to files work properly. (Fixes to BFD are also needed.)
1065 * core.c (core_open): Open file ourselves, read or r/w, depending on
1066 write_files. Use bfd_fdopenr.
1067 * gdbcore.h (write_files): New variable.
1068 * exec.c (write_files): Define variable, add set&show for it.
1069 (exec_file_command): Use write_files to open for read or r/write.
1071 Make shared library reading happen automatically. These changes
1072 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
1074 * inferior.h (stop_soon_quietly): Add to exported variables.
1075 * infrun.c (child_create_inferior): call solib hook, if defined.
1076 (child_attach): call solib hook, if defined.
1077 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
1078 (find_solib): Use lookup_misc_func rather than hand-rolled.
1079 (symbol_add_stub): New stub for catch_errors.
1080 (solib_add): Avoid output if !from_tty. Catch errors rather
1081 than just calling symbol_file_add and bombing.
1082 (solib_create_inferior_hook): Interface with the target process
1083 to let it read and alloc shared libs, then figure out what it did.
1085 * core.c (validate_files): Fix typo, soften warning.
1086 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
1088 * utils.c (fputs_demangled): Avoid duplicate printing if
1089 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
1091 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
1092 (Fix from pierre@la.tce.com (Pierre Willard).)
1094 * main.c (catch_errors): Change argument to a char * from an int,
1095 since a char * can point to a struct full of glop, but an int
1096 is not guaranteed to be able to hold a pointer.
1097 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
1098 breakpoint_re_set_one, breakpoint_re_set): Adapt.
1099 * core.c (core_open, solib_add_stub): Adapt.
1100 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
1102 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1104 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
1105 by adding .NOEXPORT target.
1107 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1111 * Makefile.in (VERSION): Roll to 4.0.
1112 (gdb.tar.Z): Make refcard.ps as well, for shipment.
1114 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1116 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
1119 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
1122 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
1124 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
1125 reflect above name change
1127 * WHATS.NEW: correct pointer to refcard.
1129 * doc/gdb.texinfo: update New Features, Installing
1131 * doc/gdbint.texinfo: add short description of configure +template
1133 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1135 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
1137 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
1139 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
1140 tar file, add dependencies for referenced doc files.
1142 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
1144 * coffread.c, symfile.c, stack.c: saberized.
1146 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1148 * doc/refcard.tex: permuted Essential Commands sec
1150 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
1152 set/show symbol-reloading
1153 default set complaints 0
1155 RET-repeat disabled after prompted long displays
1156 processID (attach) interpretation of 2nd GDB cmdline arg
1158 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
1160 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
1161 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
1162 breakpoint.c, main.c: lint.
1164 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1166 Install new configuration scheme for GDB and friends.
1168 * config.sub: Translate ordinary names to three-part names.
1169 * configure: Use three-part names internally.
1170 * configure.in: Translate three-part names to filenames.
1172 * README, WHATS.NEW: Update for gdb-4.0.
1173 * Makefile.in: Roll VERSION to 3.99.
1175 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
1177 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
1178 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
1179 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
1180 to single structures rather than arrays; when passing
1181 their address, use &. This avoids trouble with bdead compilers.
1182 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
1183 instead. This avoids portability headaches.
1184 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
1186 * source.c (open_source_file): Avoid ANSI const bdeath by
1187 skipping declaration and then casting result value.
1188 * tm-hp300bsd.h: Clarify comment.
1189 * utils.c (strstr): Result is const char *; ANSI bdeath.
1190 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
1191 since system include file defines it differently from "defs.h",
1192 though the two are equivalent for our purposes.
1193 * tconfig/hp300bsd: Add m68k-tdep.o.
1195 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1197 * tconfig/sun*4: Remove warnings about system assembler.
1199 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1201 * mcheck.c: Avoid warning about undeclared abort fn.
1202 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
1203 it causes recursive calls to error() when used in cleanups.
1204 To do so requires that we make it a function, so we do.
1205 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
1206 * utils.c (do_cleanups): Remove the current cleanup from the
1207 chain *before* calling it, in case error() is called from it.
1208 The result won't be pretty, but won't be an infinite loop either.
1210 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
1212 * dbxread.c (read_struct_type): Grok anon structs for C++.
1213 (vb_name, vptr_name): Null terminate these strings.
1215 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1217 Minor bug fixes from BSD Net2 gdb:
1219 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
1220 returns 0, there is no previous frame.
1221 * breakpoint.c (commands_command): If !from_tty, don't call
1222 input_from_terminal_p().
1223 * dbxread.c (record_misc_function): Speed up slightly.
1224 (compare_psymbols): Ditto.
1225 * infcmd.c (do_registers_info): Take a second argument to
1226 determine whether to print float registers. "info registers"
1227 does not do so anymore. "info all-registers" does, now.
1228 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
1230 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
1231 * inflow.c (initialize_inflow): Set tflags_ours correctly.
1235 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
1236 executing_breakpoint_commands if we are interrupted by error.
1237 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
1238 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
1239 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
1240 catch_errors() so we can setup the frame regardless of whether
1241 the shared libs work.
1242 * ieee-float.c (double_to_ieee_extended): Get exponent from
1243 right place in little-endian systems. From John Carey.
1245 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1247 * main.c: Remove unused terminating_signals and catch_termination().
1248 (long_options): Terminate with a zero element.
1249 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
1250 (gdb_readline): Make call-compatible with readline.
1251 (init_signals): Improve comments re vfork vs. signal.
1253 * utils.c (prompt_for_continue): Use new gdb_readline().
1254 If we prompt for continuation, we don't let CR repeat the previous
1255 command, once we get back to a prompt. It's too easy to keep
1256 hitting CR, expecting "--more--" prompts, and have some long
1257 command start repeating on you.
1259 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1261 * blockframe.c (frameless_look_for_prologue): Speed up by
1262 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
1263 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
1264 Define two variants, one faster.
1265 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
1266 and return zero, rather than giving an error.
1267 (setup_arbitrary_frame): Initialize the PC in the new frame.
1268 (skip_prologue): Add a second arg saying whether we're just
1269 checking for a frameless function or not.
1271 * core.c (core_open, core_close, core_xfer_memory): Move
1272 section table pointers and bfd* into the target_ops.
1273 (core_open): Allow errors in shared lib reading, etc.
1274 (core_files_info): Describe shared library sections.
1276 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
1277 exec_files_info, set_section_command): Move section table
1278 pointers and bfd* into the target_ops.
1279 (add_to_section_table): Add BFD to section table.
1281 * target.c (target_xfer_memory, target_info): Pass target to
1282 xfer_memory and target_info functions.
1285 * gdbcore.h: Move struct section_table.
1286 * target.h: New home of struct section_table.
1288 * solib.c (solib_add): New argument is the target_ops whose
1289 section list is to be added to, if any. Reallocate the
1290 sections in that target to add any that come from shared libs.
1291 (throughout) so_sections renamed to sections.
1292 (solib_xfer_memory): Deleted.
1293 * tm-sunos.h (SOLIB_ADD): Add target argument.
1294 (SOLIB_XFER_MEMORY): Delete.
1296 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1297 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
1298 from target_ops. It's the same on all targets. Add two section
1299 pointers to target_ops.
1301 * stack.c (find_relative_frame): Dump ancient algorithm for
1302 "down", just use handy "next" pointers.
1303 (frame_command): Don't error if there is no stack; let user
1306 * inflow.c (new_tty_prefork, new_tty): New prefork routine
1307 modifies static state in the parent process; new_tty itself
1308 runs in the child and modifies the child's file descriptors
1309 to match the saved static state.
1310 * infrun.c (child_create_inferior): Call new_tty_prefork,
1313 * infptrace.c (child_xfer_memory): Add ignored target arg.
1314 * remote-eb.c (eb_xfer_inferior_memory): ''
1315 * remote-nindy.c (nindy_xfer_inferior_memory): ''
1316 * remote-vx.c (vx_xfer_memory): ''
1317 * remote.c (remote_xfer_memory): ''. Rename from
1318 remote_xfer_inferior_memory.
1320 * main.c (main): Only try to attach "corefile" argument if
1321 it starts with a digit.
1323 * symfile.c (symbol_reloading): New "set/show" variable.
1324 (symbol_file_add): Shorten message about symbol reading.
1325 (add_symbol_file_command): Merge with add_syms_addr_command,
1326 since this should work on all targets now.
1327 (stop_whining): Default to zero, to shut up complaints
1328 about bad symbol tables on many systems.
1329 (free_named_symtabs): Just exit unless symbol_reloading.
1331 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
1332 and add comment explaining shared library screw.
1334 * source.c: #if defined => #ifdef.
1336 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1338 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
1340 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1342 * doc/rdl-apps.texinfo: provide default readline-appendix finder
1343 (doc/Makefile knows how to make one for local config)
1345 * Makefile.in: use doc/Makefile for doc targets
1347 * doc/Makefile: GDB documentation now has its own Makefile
1348 doc/refcard.tex: renamed from "gdbrc.tex"
1349 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
1350 doc/gdbint.texinfo: add markup in "Cleanups" chapter
1353 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1355 * values.c (baseclass_addr): When reading target memory, use the
1356 length of the basetype, not the upper type. We've only malloc'd
1357 enough space for the basetype, leading to errors in free().
1359 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
1360 ends up as a function specially, since we know the actual type of
1361 the pointed-to address. This (somewhat) fixes display of
1362 expressions that include misc_function_vector names. Try `cond 1
1363 !strcmp("a","b")' then `i b'.
1365 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
1366 The child can be proceeded from inside wait_for_inferior in
1367 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
1368 getting skipped in that case.
1370 * expprint.c (print_subexp): Use filtered output, since the
1371 subroutines we call use it, otherwise the output is horribly
1372 mangled, since output of wrappable stuff comes out late.
1374 * Makefile.in: Bump VERSION to 3.98.1
1376 * infrun.c (child_create_process): Use execlp to find the
1377 shell to exec our target program. This requires some fiddling
1378 with `environ' since there is no execlpe().
1380 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1382 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
1383 Minor rearrangement of refcard permits two new make targets--
1384 gdbrc.dvi DVI output for refcard, using CM fonts
1385 gdbrc.ps PostScript refcard, using PS fonts
1387 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1391 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
1392 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
1394 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1396 * doc/gdb.texinfo: last changes for release.
1397 Minor typo and formatting fixes; incorporated most fixes remaining from
1398 filed mail commenting on earlier drafts.
1400 Added warnings: pipes don't work in run command;
1401 conditions are converse of assertions;
1402 step over fn without debug info goes to next fn;
1403 vars may have "wrong" values near fn entrance, exit
1405 Added example from Kingston on printing repeated nonadjacent values
1407 Added explicit mention that in Emacs gdb mode C-c and C-z are like
1408 shell mode for signals
1410 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
1411 doesn't sound so much like its parent "Stopping and Continuing"; also
1412 moved entries on continue to top of section, so they don't get lost.
1414 Improved installation directions in appendix, added manual formatting
1417 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1419 * configure.in: Remove xm.h and tm.h even if we aren't linking
1420 new ones, so "./configure sun4; ./configure none" does the right
1421 thing. Assume that alldeps.mak and depend are already built in
1422 srcdir, and avoid running "make" (particularly "make depend",
1423 which involves "gcc") from inside configure. Build Makefile
1424 directly rather than building Makefile.conf first.
1425 * configure: Regenerate with above changes.
1426 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
1427 to 3.98. Revise gdb.tar.Z procedure to produce a file
1428 called gdb-$(VERSION).tar.Z but which unpacks into a
1429 directory called "gdb". Move non-source files out of
1430 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
1431 (depend): Don't try to do "gcc expread.y".
1432 (expread.o): Update dependencies by hand.
1434 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1437 Fixed a variety of small typos that prevented info from formatting
1438 cleanly; altered too-long heading for GPL Appendix, as discussed
1439 w/RMS; Changed date on cover to July 91.
1441 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1444 (1) Applied some fixes due to comments from Larry Breed (easier ones
1445 through chapsec 5.2)
1446 (2) Eliminated use of @footnote---had my doubts about it anyways, and
1447 it's broken in latest texinfo
1448 (3) Introduced *some* use of [] for optional arguments, where
1449 explanation is not simpler by listing cmd w arg and cmd w/out arg
1450 separately. Still not using @deffn.
1451 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
1452 couple of headings are too long. Need patches to texinfo or revision
1455 * Partial update to README (which still needs work for this
1456 release!): (1) use of configure corrected for new script,
1457 (2) "make gdb.dvi" and "make gdb.info" mentioned.
1459 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
1461 * symtab.c (lookup_symbol): Don't complain right off about
1462 no debug symbols; use the misc function vector first.
1463 (list_symbols): Use misc function vector to find symbols
1464 that don't have debug info, and print them.
1465 (find_pc_symtab): Temporarily avoid fatal() when psymtab
1466 PC range doesn't match symtab PC range, as it does on the
1467 MIPS because our symtab reading isn't perfect.
1469 * dbxread.c (dbx_symfile_read): Make warning about
1470 "no debug symbols" slightly nicer.
1472 * source.c (select_source_symtab): If "main" symbol exists,
1473 but decode_line_spec can't find line info, don't just return
1474 a zero; try other source symtabs or give an error.
1476 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
1477 their low addresses first, then rip through fixing high addrs.
1479 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
1480 <runene@ifi.uio.no>.
1481 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
1483 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1485 * Minor, mostly mechanical, cleanup of doc subdir for clean
1486 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
1487 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
1489 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
1491 Mostly MIPS and general symbol-reading fixups.
1493 * doc/gdbint.texinfo: Add documentation on symbol-reading
1496 * mipsread.c: Remove kludges around #include "ecoff.h".
1497 Remove redefinitions of a_magic, etc, no longer used.
1498 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
1499 Fix global overview comments to match symfile.c protocol.
1500 (mipscoff_new_init): Eliminate cur_hdr if we have one.
1501 (mipscoff_symfile_read): Eliminate unused code. Avoid
1502 sorting all the symtabs, when all we have read here is psymtabs.
1503 The symtabs are sorted as they are created anyway. Tell
1504 condense_misc_bunches whether we're mainline.
1505 (psymtab_to_symtab_1): Pass filename when recursing, to make
1506 stack trace more informative.
1507 (parse_partial_symbols): Assume cur_hdr as argument.
1508 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
1509 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
1510 the TYPE_NAME of char *, since that's done in symfile.c.
1511 (free_numargs, parse_symbol, add_symbol, add_block,
1512 shrink_linetable): Declare these fns void.
1513 (upgrade_type): Convert tree of if's to switch. Clean up
1514 bogus "off == 0" handling with a complaint. Avoid setting
1515 field bitpos and bitsize of array with lower and upper bounds.
1516 Check specified bitsize of elements against their actual type's
1517 bitsize, and complain if different. Complain about unknown
1519 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
1520 (psymtab_to_symtab_1): Print names of subsidiary files that
1521 are being read in. FIXME, we read far too many files. This code
1522 is not the problem, the problem is in parse_fdr where the psymtabs
1524 (cross_ref): Result should indicate that we used one aux entry
1525 normally, or two if we encountered a "next" entry. This used
1526 to leave the caller pointing at the wrong aux entry.
1527 (add_symbol): If overflowed cur_block, reallocate it larger,
1528 chase all pointers to it, and complain(), rather than clobber memory.
1529 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
1530 (new_field): Only allocate one field initially, not two.
1531 Pull ++ out of macro argument. Simplify.
1532 (_initialize_mipsread): Avoid initialization of importd
1533 global_psymbols and static_psymbols.
1535 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
1536 to properly set pst->symtab; avoid searching for it.
1537 (symfile_fns): Improve comments, add a FIXME.
1538 * dbxread.c: Update comments to reflect symfile protocol.
1539 (read_ofile_symtab, end_symtab): Return the symtab.
1540 (psymtab_to_symtab_1): Set pst->symtab.
1542 * coffread.c (coff_symfile_read): tell condense_misc_bunches
1543 whether we're mainline.
1545 * symfile.h (sym_fns): Remove unused sym_discard member.
1546 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
1548 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
1549 the environment variable is not.
1550 * infcmd.c (finish_command): Use filtered printfs.
1551 * cplus-dem.c: Add struct tags to a few unnamed structs.
1552 * valops.c (value_coerce_array): Improve comments.
1553 * valprint.c (type_print_varspec_suffix): Print array size only
1554 if greater than zero.
1555 * m88k-tdep.c: Shift some lines left by one space, that had
1556 apparently been trashed at some point.
1557 * TODO: More things to do, a few got done.
1559 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1561 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
1562 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
1564 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
1565 * expread.y, findvar.c, symmisc.c: Ditto.
1566 * printcmd.c (address_info): Update printed forms of LOC_
1567 symbols. Elim LOC_EXTERNAL.
1568 (print_frame_args): Keep track of param stack offsets before
1569 re-looking up to find the local register param is kept in.
1571 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
1572 Further integration of mipsread into gdb. Eliminate unused
1573 routines, duplicate declarations. Handle static symbols in
1574 psymtabs as well as external symbols. When reading symtabs,
1575 insert symbols into the correct block (global, static, or a local
1577 (read_mips_symtab, parse_partial_symbols): Don't pass useless
1579 (mipscoff_symfile_read): Don't call select_source_symtab.
1580 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
1581 rather than SYMBOL_VALUE.
1582 (parse_external): Comment clobbering of top_stack.
1583 (parse_partial_symbols): Update comments. Allocate and parse
1584 static symbols as well as external symbols. FIXME, enum values
1585 are not handled in this pass, but should be. Inline new_psymbol.
1586 Use SYMBOL_VALUE_ADDRESS.
1587 (psymtab_to_symtab_1): Read symbols into global static block
1588 by default (until enter some function's local block context).
1589 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
1590 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
1592 * source.c (select_source_symtab): Select a source symtab
1593 from either the symtabs or, failing that, the psymtabs.
1594 (list_command): Update error message.
1595 (forward_search_command, reverse_search_command): Use getc, not
1596 fgetc, for speed. FIXME, add comment about buffers that die if
1597 overrun by long line.
1599 * values.c (unpack_field_as_long, modify_field): Avoid shifting
1600 by an entire word, which is not portable, if we have a 32-bit
1601 field. (Code in dbxread.c already turns such bitfields, if
1602 aligned, into ordinary ints, but fixing this will help for other
1603 symbol formats and for future changes.)
1604 * core.c (core_open): Handle ANSI const brain death.
1605 * utils.c (vprintf): Fix varargs typo.
1607 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1609 * findvar.c (find_var_value): Handle &function better.
1610 * TODO: Document work needed on &fn and &array.
1611 * printcmd.c (print_address_symbolic): New arg is the prefix
1612 to print if a name is printed.
1613 (print_address_demangle): Honor "set print address" now.
1614 Use new arg above to improve spacing of output.
1615 * valprint.c (val_print): When printing function pointers,
1616 print symbolic form too.
1617 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
1619 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1621 * core.c (memory_error): Reword error msg to mislead less.
1623 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
1625 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
1626 parse_partial_symbols): Use newer BFD internals (external_filehdr
1627 and external_aouthdr), byte-swap the fields that we care about
1628 before using them, and make the file header data local to
1629 read_the_mips_symtab rather than global.
1631 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
1633 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
1634 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
1636 * main.c (command_line_input): Flush stdout and stderr
1637 before every call to readline. This reportedly fixes a bug
1638 that comes up in Sys V running emacs-gdb and/or xxgdb,
1639 when stdin/out are pipes or sockets.
1641 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1643 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
1644 Avoid declaring Makefile dependencies, because GNU Make stupidly
1645 tries to update it if we do.
1647 * coffread.c: Revise for minor changes to bfd internal coff
1650 * configure: If -template= is given a relative path, make it
1651 absolute before recurring in subdirectories.
1653 * configure, configure.in, Makefile.in: Install "configure" script
1654 as replacement for config.gdb.
1655 * config.gdb, Makefile.dist, Makefile.sdir: Remove
1656 * README: Update for configure, mostly. FIXME.
1658 * Add dec3100 as equivalent to littlemips. Indicate in all host &
1659 target config files that they are for the host. When the lines
1660 get copied into the Makefile, this makes it more obvious what's
1663 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1665 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
1666 tabs, which end up in the disassembler output inadvertently.
1668 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1670 Make it compile cleanly in an ANSI GCC2 environment.
1672 * blockframe.c: <stdio.h>
1673 * cplus-dem.c: free takes a void *, ifdef __STDC__
1674 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
1676 * defs.h (alloca): Avoid doing anything if alloca already def'd.
1677 * stddef.h, stdlib.h: Remove these files.
1678 * symtab.c: Avoid declaring qsort, close.
1679 * symfile.c: Avoid declaring close.
1680 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
1681 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
1683 Assorted other changes.
1684 * dbxread.c: include "libaout.h", not "liba.out.h".
1685 * printcmd.c (print_frame_args): Set recurse properly for
1686 indentation of struct and array parameters.
1687 * valops.c (value_cast): Allow cast to void.
1688 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
1689 single_step() in a target-independent fashion.
1690 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
1691 set up to be ready to continue. This makes us target independent.
1692 * infptrace.c (child_resume): Remove call to single_step; now
1693 can single step a SPARC target of any kind.
1695 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1697 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
1698 docn into separate sections---basically chapters, plus two loose
1699 pieces that can be configured to go in different places. This
1700 allows GNU m4 to preprocess the manual without coredumping.
1702 * Makefile.dist: tell TeX where to find texinfo.
1704 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1706 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
1707 the new target "rdl-apps.texinfo" which captures the Makefile
1708 variable that records where to find the Readline libraries.
1710 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
1712 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
1713 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
1714 * defs.h (const, volatile): Only define if not already defined.
1715 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
1717 * README: Update for release 3.95.
1718 * config.gdb: Don't create readline dir in subdir builds.
1719 * main.c: Include with "..." form for non-system include files,
1720 so "gcc -MM" for "make depend" works.
1721 Include readline files with "...h" rather than <readline/...h>.
1722 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
1724 * coffread.c: Undo minor damage done by Rich Pixley. Use
1725 different internal and external representations of COFF
1726 data structures. Use new BFD routines for swapping them in and
1728 * symfile.c (free_named_symtabs): Avoid freeing file names that
1729 are null or empty. Old i960 tools seem to produce files that
1730 claim to have empty names, causing each successive file read
1731 to blow away the previous one.
1732 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
1733 Move deferred_stores to top of file, but don't separate its
1734 #define's from its variable. Add commentary.
1735 * Makefile.dist: Fix Rich damage; undo "configure" changes in
1736 favor of keeping the (working) config.gdb. Move readline
1739 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
1741 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
1743 * infptrace.c (fetch_registers): no result, since now void.
1744 * tconfig/news: target depends on m68k-tdep too.
1746 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1748 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
1751 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
1752 applied various small fixes due to or inspired by RMS comments
1754 * doc/gdb.texinfo: finished using all RMS comments, save those for
1755 appendices on readline and cmd history (which are in other source
1758 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1760 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
1761 chapter 9; (2) documented 'break' command's menu mode for
1762 overloaded names, in response to hgs problem report C++ p-31
1764 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1766 * doc/gdb.texinfo: (1) better introductory example; (2) more
1767 consistent use of @code, @samp, @file, @kbd throughout; small
1768 cleanups to first three nodes; (3) new "Contributors" node;
1769 (4) Appendix, Renamed Commands; (5) divert specialized startup
1770 instructions to "Targets" chapter for generic manuals, while
1771 leaving them up front for manuals specific to specialized
1772 environments; (6) apply fixes from RMS comments through chapter 4.
1774 * pretex.m4: modify explanatory text slightly (and redefine
1775 "regexp") to keep GNU m4 from complaining. (It still crashes
1776 later, but one step at a time...)
1778 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
1780 * readline/readline.c (update_line): Avoid dereferencing a pointer
1781 before comparing it to its bounds. Saber caught this.
1782 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
1783 and only set PC if tgetstr returned non-null. Saber caught this.
1785 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1787 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
1788 stuff for config manual) here where it counts; updated
1789 to use new subdir structure (gdb/doc/).
1791 * Makefile: generated from above via
1795 * gdbint.texinfo: added instructions on generating gdb.info* files
1796 locally for release. These are ordinary info
1797 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
1798 Makefile)---but due to use of texinfo 2, can't count on makeinfo
1799 to generate these, so we distribute them already formatted.
1801 * gdb.texinfo: included full Info node and menu crud (as generated
1802 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
1804 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
1805 put in comments-for-future gdb.info target (one day makeinfo will
1808 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1810 * gdb.texinfo: Updated to include new or old undocumented
1811 commands, at least the following (perhaps some others I forgot to
1812 record): info f, info float, info path, info program, info s, info
1813 set, info source, info terminal, info types, info user, set/show
1815 Also covered all recent GDB command renames for v4.
1817 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1819 * mipsread.c: Rather than keeping count of how many symtabs
1820 and psymtabs we have, for sorting purposes, count them when
1821 we need to sort. This fixes bug in rereading of symbol tables.
1823 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1825 * infcmd.c: renamed "info path" to "show paths"
1826 * gdbrc.tex: documented above.

1836 Fix up "saber_gdb" to work again.
1837 * saber.suppress: Update.
1839 * coffread.c, exec.c, infptrace.c, inftarg.c, remote.c, solib.c,
1840 symtab.h, target.c, target.h: Lint.
1841 * core.c: setup and select frame after reading shared libs,
1842 else reading shared libs will clobber them. Lint.
1843 * utils.c (error): Force out any buffered wrap text.
1845 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1847 * remote.c: Remove decls of memory_insert_breakpoint
1848 and memory_remove_breakpoint, no longer used. (Suggestion of
1851 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
1852 to make it easier to interface to "configure"'d libraries.
1854 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
1856 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
1857 aliases for set/show print.
1859 Thu May 2 11:22:02 1991 Jim Kingdon (kingdon at cygint.cygnus.com)

1909 dc_dcontext_t not int.
1911 * coffread.c [TDESC]: Use system include files not <intel-coff.h>.
1913 * coffread.c [TDESC]: Move setting of debug_info from
1914 coff_symfile_read to find_linenos and make it work with BFD.
1916 * cplus-dem.c [__STDC__]: Make x{m,re}alloc return void*.
1918 * signame.c: Cast const char* to char* when assigning to sys_siglist.
1920 * utils.c (strsave): Make arg const char* not char*.
1922 * infrun.c (wait_for_inferior) [SHIFT_INSN_REGS]: Use
1923 bpstat_explains_signal (stop_bpstat) not stop_breakpoint.

1943 Mips bringup and general cleanup
1945 * cplus-dem.c: Move CPLUS_MARKER define to after defs.h.
1946 * infptrace.c (PT_WRITE_D, PT_READ_D): Use correct values.
1947 (This still doesn't seem to make MIPS bkpts work.)
1948 * mipsread.c: Remove dup "Reading symbol data..." msg.
1949 (symbol_file_command, add_file_command): Remove, obsol.
1950 * printcmd.c (ptype_command): Say "an enum" rather than "a enum".
1951 Wrap output appropriately.
1952 * stack.c (locals_info, catch_info, args_info): Check
1953 selected_frame rather than target_has_stack or coredumping.
1954 * valprint.c (type_print_varspec_suffix): Wrap "ptype" output of
1955 enums appropriately.
1957 Wed May 1 14:10:22 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
1959 * signame.c: Include defs.h and param.h.
1961 * cplus-dem.c: Include defs.h and param.h.
1962 Makefile.dist: Don't hack in the "param.h".
1963 param.h: Don't include defs.h.
1965 * expread.y: Use a union to deal with the fact that type_stack
1966 can have both ints and enum type_pieces in it.
1967 ({push,pop}_type_int): New functions.
1969 Tue Apr 30 13:18:58 1991 Jim Kingdon (kingdon at cygint.cygnus.com)

1981 symtab.c, cplus-dem.c, value.h, expread.y, valprint.c,
1982 copying.awk, solib.c, inflow.c, symmisc.c

2450 * symmisc.c (free_named_symtab): Make it work, in its current
2451 kludgy fashion. Change result to indicate if we blew away bkpts.
2452 * dbxread.c (end_symtab): Accumulate result from
2453 free_named_symtab and print warning if we blew user's state.
2454 * symfile.h: free_named_symtab now returns an int.
2456 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
2458 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
2459 is the first symbol read, even if not mainline.
2460 (dbx_psymtab_to_symtab): symfile might be zero, cope.
2461 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
2462 (set_section_command): New command ("section xxx yyy" -- should
2463 be renamed to "set section xxx yyy" FIXME) which sets the
2464 base address of a section of the exec file, overriding the
2465 virtual address that BFD reports.
2467 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2469 * exec.c: Add add_syms_addr_command to exec_ops, so you can
2470 load symbols at any address while examining an exec file.
2472 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
2474 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
2475 for printing the float info is host-dependent, not
2476 target-dependent. FIXME.
2477 * i386-pinsn.c: Move #includes to top, remove useless ones.
2478 * i386-tdep.c: Don't bother including <.../reg.h> since we
2479 don't use it (and it doesn't exist on host systems).
2481 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
2482 Convert negative numbers properly.
2483 (ieee_test): Make numbers really random; fix format arg.
2485 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
2486 * core.c (core_detach): Unpush core_ops, which might not be on
2487 top. We used to just pop the top, which broke things. Don't
2488 need dont_repeat() any more.
2489 (core_file_command): Psst! Don't repeat it.
2490 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
2491 * expprint.c (print_subexp): Avoid switch fallthru on
2492 BINOP_ASSIGN_MODIFY, so we can print += and such.
2493 * frame.h: Fix typo.
2494 * inflow.c (kill_command): After killing inferior, print our
2495 current frame in the core file, if we have one.
2496 (generic_mourn_inferior): When inferior dies, either select
2497 the current frame (in the new target, e.g. core file), or
2498 set both the current and selected frames to NULL.
2500 Changes from Peter Schauer.
2502 * infptrace.c: Avoid <sys/ptrace.h> on USG.
2504 * Make all file names fit in 14 characters (sigh and damn!):
2505 mv hp300hpux-xdep.c hp300ux-xdep.c
2506 mv symmetry-xdep.c symm-xdep.c
2507 mv symmetry-tdep.c symm-tdep.c
2508 mv convex-opcode.h convx-opcode.h
2509 mv tm-vxworks960.h tm-vx960.h
2510 mv tm-vxworks68.h tm-vx68.h
2511 mv Makefile.srcdir Makefile.sdir
2512 mv gdb-int.texinfo gdbint.texinfo
2513 mv remote-sa.m68k.shar rem-m68k.shar
2514 mv remote-multi.shar rem-multi.shar
2515 * Makefile.dist, README, config.gdb, convex-pinsn.c,
2516 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
2517 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
2520 * command.c (user_info_1, user_info): New command for listing
2521 the user-defined commands.
2523 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
2525 * dbxread.c (really_free_pendings): Clear file_symbols
2526 and global_symbols after freeing them; otherwise, running
2527 this function twice (if it appears twice on the cleanup
2528 chain), we try to free things twice.
2530 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
2531 based on text_addr (the address of text in core), not on addr (the
2532 offset between text in the .o file and in core). This change
2533 is from Peter Schauer.
2535 * main.c: Define ALL_CLEANUPS as a cast of zero.
2536 (return_to_top_level): Use it.
2537 (main): Do all cleanups after each command run as part
2538 of the gdb startup sequence. Also do all cleanups before
2539 entering the command loop, and every time we exit the command
2540 loop and reenter. Before, the cleanups from the startup sequence
2541 were being left undone until the first error!
2542 (command_loop): Rename do_nothing cleanup to command_loop_marker
2543 so we can see it easily when examining the cleanup chain.
2544 (init_signals): Add another do_nothing for signal handling.
2545 (quit_command): Only try to kill target if it has execution.
2546 Problems in the target stack got us into a state where
2547 inferior_pid was nonzero but none of the targets had execution.
2548 In this state you couldn't exit gdb.
2550 * dbxread.c: Two changes from Peter Schauer.
2551 (echo_command): Fflush output after an echo command.
2552 (show_history): Pass all args to cmd_show_list.
2554 * utils.c (init_malloc): Call mtrace to turn on tracing
2555 if the environment variable MALLOC_TRACE is set to a file name.
2556 * mtrace.c: Add source file which provides a log of every malloc,
2557 free, and realloc to a trace file.
2558 * mtrace.awk: Add source file which analyzes the trace file.
2559 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
2560 (VERSION): Roll to 3.94.3.
2562 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
2563 (check_duplicates): Don't bother with watchpoints.
2564 (set_raw_breakpoint): Comment about danger of this routine.
2565 (watch_command): Parse and eval all args before calling
2568 * solib.c (find_solib): Avoid error in referencing memory to
2569 see if any more shared libraries have been added. This is
2570 particularly useful if the target has terminated. Bug reported
2573 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
2574 in bringing up 3.94.2 on the Sun-3.
2576 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
2577 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
2578 expression (in scope) before reenabling watchpoint.
2579 * signame.c (init_sigs): Add missing declaration of i, fix
2580 sys_siglist declaration.
2581 * source.c (list_command): Fixed range computation to use
2583 * stack.c (backtrace_command): Do not allow command if target has
2584 no stack, print informative error message.
2585 * target.c (target_command): Do not write into command line
2586 because this fails if the target command is used in a user defined
2587 command. [This change was enhanced by gnu to support any-
2588 unique-prefix matching on target names.]
2589 * valops.c (value_struct_elt): Avoid infinite loop on an
2590 erroneous attempt to print the member of function (try p main.p).
2592 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
2594 * expread.y (name_no_typename): Avoid reduce/reduce errors
2595 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
2596 Since the GDB parser really doesn't use name_no_typename in a
2597 name-only context, the parser can't tell the diff between
2598 names and numbers here. Avoid allowing a name_no_typename
2599 to be a NAME_OR_*INT to resolve the conflict.
2601 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2603 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
2605 * valprint.c (val_print_fields): bitfield printing didn't handle
2606 byte order. Indirect through a few more fns to cope.
2608 * values.c (modify_field): also cope with byte order.
2610 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2612 Cleanup for release 3.94.2:
2614 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
2615 include files. Roll version to 3.94.2.
2617 * coffread.c (init_stringtab): Read length into unsigned char
2618 array before swapping; don't assume 32-bit longs.
2620 * target.c (target_info): Don't bother with get_sym_file, just use
2621 the symfile global variable.
2622 * symtab.h, symfile.c (get_sym_file): Delete it.
2624 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
2625 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
2626 (read_type): Replace one more error() with complain().
2628 * mipsread.c (parse_partial_symbols): Replace printf with complain.
2630 * i960-tdep.c: Fix copyright attribution.
2632 * config.gdb: Quote all backquotes in doublequotes. You can
2633 quote me on that. BSD 4.4 shell found this one.
2635 * infptrace.c (throughout): The third argument to ptrace is an
2638 * infrun.c (wait_for_inferior): When program has terminated, we
2639 have to call target_terminal_ours before we pop that target off
2640 the stack (e.g. before a call to target_kill or
2641 target_mourn_inferior). This fixes problem where a program
2642 terminates, then GDB stops for (tty output) and you have to type
2643 "fg" to the shell to resume it. FIXME: This code for what to
2644 do after termination really should be in normal_stop instead.
2646 * gdbcore.h (read_memory_check): Change declaration; it changed
2649 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
2650 4.4 prereleases, this avoids a bug in their sgtty compatability
2652 * remote.c: Use terminal.h rather than hand-rolling the same.
2654 * signame.c, signame.h (psignal): Arg is unsigned, not int.
2655 * utils.c (strsave, strstr): Fix arg types.
2656 * valprint.c (val_print): lint
2658 MIPS symbol table support from Per Bothner:
2660 * symfile.c (symtab_fns): Remove initializer table that needs to
2661 be hacked for each new symbol file format supported.
2662 (add_symtab_fns): New function, chains symbol table
2663 handlers into the global list.
2664 (symfile_init): Search this list.
2665 * symfile.h: Add next pointer, declare add_symtab_fns.
2666 * coffread.c (_initialize_coffread): Call add_symtab_fns.
2667 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
2669 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
2670 symbol *). Thus, we no longer need the hack to trash
2671 pst->filename. Good, since that hack confused code in symfile.c!
2673 (reorder_symtabs, destroy_all_symtabs): Removed static
2674 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
2675 Instead, the latter now uses a temporary array (stack-allocated
2676 from an obstack, and then freed).
2678 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
2679 haven't been set in the outermost stBlock of a procedure. This was
2680 a problem with f77 binaries on Ultrix 4.?.
2682 (new_symtab, new_symbol, new_type): Continue changing code to use
2683 obstacks more and otherwise conform to dbxread internal style.
2684 Made the free_code of symtabs be free_linetable (as in dbxread)
2685 instead of free_contents. This implies memory leaks when reading
2686 a new symbol table, until the conversion is finished. Did change
2687 (struct symbol) and (struct type) to be allocated on the
2688 symbol_obstack. Blocks and blockvectors are among the things
2691 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
2692 tested much, but it solved one problem (reported by Meissner), and
2693 cleans up some other things. The problem happened when an
2694 included file contains actual code (functions) and not just
2695 definitions. The mips coff is a little inconvenient there, since
2696 it may cause a procedure to be mapped to the wrong psymtab.
2698 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
2699 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
2700 this will need work for the new core paradigm.
2702 Opcode patches from the net:
2704 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
2705 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
2706 missing altogether - they are added here. From Bruce Bauman.
2707 * mips-opcode.h: The low mask for C0 instructions was too small.
2708 From Garrett Lau. I modified the fix to check the entire 32-bit
2711 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
2714 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2716 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
2718 * dbxread.c (read_type): Pointer subtraction (value_sub in
2719 valarith.c) sometimes failed because the types of the
2720 pointers being subtracted were not identical.
2721 These differed because dbxread.c was allocating pointer types
2722 using dbx_alloc_type+smash_to_pointer_type instead of
2723 lookup_pointer_type. I failed to find a justification for the
2724 former, so I changed it to use the latter. Similarly, I
2725 replaced smash_to_function_type by lookup_function_type,
2726 and smash_to_reference_type by lookup_reference_type.
2728 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
2729 _initialize_mipsread): corresponding changes.
2731 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
2733 * source.c (mod_path): Do tilde_expand on each component of the path,
2734 rather than on the (list of) paths as a whole.
2735 (print_source_lines): Set first_line_listed in addition to
2736 current_source_symtab and current_source_line. If the source was
2737 not findable, after a "dir" command to fix the problem,
2738 a "list" would get the wrong lines.
2740 While I was there... (gnu):
2742 * dbxread.c (read_type): Change error to complaint.
2744 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2746 First attempt at detailed understanding of symbol table memory alloc.
2748 * dbxread.c (dbx_symfile_read): Free our string table if we
2749 aren't the mainline. Free the "info" struct since we're done with
2751 (init_psymbol_list): Free any previously allocated psymbol lists.
2752 (): FIXME: Should realloc-down the psymbol lists when done reading
2753 the main symbol file?
2755 * symmisc.c (free_symtab): Free fullname field too.
2757 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
2758 (REGISTER_ADDR): Make result type unsigned int.
2760 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
2761 define REGEX must also define REGEX1 (its dependency).
2763 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
2765 * tconfig/i960: No longer works, points you at vxworks960 or
2768 * xgdb.c, XGDB-README: Remove file. Users can get the much
2770 * Makefile.dist: Remove all trace of xgdb.
2772 * breakpoint.c (breakpoint_1): Pass demangle arg to
2773 print_address_symbolic.
2774 (clear_breakpoints): Remove unused function.
2775 (breakpoint_re_set_one): Guts of breakpoint_re_set.
2776 (breakpoint_re_set): Use catch_errors to do them all anyway.
2778 * gdb-int.texinfo (Host versus Target): Add section on what is
2779 a "host" feature versus what is a "target" feature.
2781 * infcmd.c (path_command, path_info): Handle the PATH variable
2782 (object search path) as conveniently as the source search path.
2783 * environ.c (set_in_environ): Set some vars in GDB's environment,
2784 in addition to the child's. PATH, G960BASE, G960BIN for starters.
2785 * source.c (mod_path): New function, from guts of
2786 directory_command, modifies a path. Used by path_command.
2787 (directory_command): Call it.
2788 * defs.h (strsave): Declare.
2790 * utils.c (sevenbit_strings): Add new printing option.
2791 (printchar): Use it.
2792 (strsave): Provide this handy helper routine.
2793 (set_width_command): Rename set_screen_width_command.
2794 (_initialize_utils): "set screen-width" => "set width";
2795 "set screen-height" => "set height"; add sevenbit-strings.
2797 * infcmd.c (do_registers_info): Print floating point registers
2798 in raw hex as well as float format, regardless of whether it is
2799 a "virtual" convertible register.
2800 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
2801 regs as a double, just in case it's being used that way.
2802 * values.c (unpack_long): Comment on array/function coercion.
2803 (unpack_double): Argument is in target byte order now. For
2804 integer arguments, just call unpack_long and float the result.
2805 * m68k-tdep.c: include defs.h for "const" handling.
2806 * remote-nindy.c: Use ieee-float stuff.
2807 (nindy_fetch_registers): Unpack double regs to host double, then
2809 (nindy_store_registers): Pack extendeds to host double, flip
2810 around by misusing unpack_double, send as target double.
2812 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
2813 zero, as when stopped at the first instruction of a process.
2815 * blockframe.c: Fix filename in comment (param.h => tm.h).
2816 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
2817 * tm-68k.h: Fix typos.
2819 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
2821 Changes from a bringup on the DEC Vax under Ultrix 4.0.
2823 * coredep.c (fetch_core_registers): Pass end-address of register
2824 section to register_addr as expected. Don't call supply_register
2825 if we'd just pass it garbage.
2827 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
2829 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
2831 * target.c (push_target, target_info): Cast enums to int for < or
2834 * stack.c (print_frame_info): Identify source file & line
2835 even if we can't print it.
2837 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
2839 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
2841 Clean up IEEE floating point support.
2843 * ieee-float.h: New file.
2844 * ieee-float.c: Write real routines to convert between host
2845 doubles and various target IEEE extendeds.
2846 * m68k-xdep.c: Eliminate assembler code for extended floats.
2847 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
2848 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
2849 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
2850 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
2851 double_to_ieee_extended.
2852 * i960-tdep.c: Define ext_format_i960.
2853 * m68k-tdep.c: Define ext_format_68881.
2854 * sparc-tdep.c: Define ext_format_sparc, though unused.
2855 * Makefile.dist (HFILES): Add ieee-float.h.
2856 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
2859 Obsolete the "coffstrip" program in favor of using BFD's strip.
2861 * nindy-share/coffstrip.c: Remove file.
2862 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
2863 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
2864 * tconfig/nindy960: Remove reference to coffstrip.o.
2866 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
2868 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
2870 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
2871 * dbxread.c: Remove static symfile_bfd.
2872 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
2874 * inftarg.c (child_detach): Pop the child_ops vector if the
2875 detach is successful.
2876 * remote-nindy.c (nindy_create_inferior): Don't push a new
2877 nindy_ops since nindy uses the same one for execution and memory
2879 * core.c (core_ops): Use child_attach and child_create_inferior
2880 rather than default attach and create_inferior functions.
2882 Handle floating point registers in core files.
2884 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
2885 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
2886 This version untested since BFD doesn't yet support sun3 core
2888 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
2889 conventions. Fix comments and style. This version has not
2890 been compiled yet, since we have no HP inhouse.
2891 * core.c (get_core_registers): Look for two sections, ".reg"
2892 and ".reg2", and pass both to fetch_core_registers sequentially.
2894 Revise directory path yet again.
2896 * source.c (forget_cached_source_info): Not static any more.
2897 (init_source_path): New default source path is "$cdir:$cwd".
2898 (dir_command): Handle variable arguments ($cdir, $cwd).
2899 (source_info): Print "Compilation directory" rather than
2900 "Originally compiled in" to remind people of $cdir.
2901 (openp): If the path contains $cwd, use current directory.
2902 (open_source_file): If compilation directory is known, replace
2903 first $cdir in path with the compilation directory.
2904 (print_source_lines): Even if we can't print the lines, set the
2905 current symtab and line for future commands like "info source" or
2906 "breakpoint". Also, error message now contains the file name,
2907 line number, and file access error message.
2908 (_initialize_source): Fix help text to describe changes.
2909 * main.c (cd_command): Forget cached source info when we chdir.
2910 * utils.c (strstr): Add simple implementation.
2912 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
2914 * coffread.c (read_one_sym, init_linetable, init_stringtab):
2915 Byte-swap COFF symbol tables if necessary when reading them in.
2916 Use complain() to replace error message in one spot. Needs
2917 corresponding change in bfd/coff-code.h to make some symbol
2918 swapping routines non-static.
2920 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
2922 Merge changes from Eirik Fuller, for UTek.
2924 * defs.h (errno): Add declaration.
2925 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
2926 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
2927 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
2928 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
2929 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
2930 declarations of errno.
2932 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
2934 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
2935 <rpc/rpc.h> and <rpc/types.h>.
2937 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
2939 * i960-tdep.c (examine_prologue): Add new argument limit,
2940 which stops the scan at the end of the prologue, or at the PC.
2941 This fixes a problem where it walks down into the code for the
2942 user's statements if that code looks like function prologues.
2943 Mark Fox and I have been bouncing this code back and forth, making
2944 small changes to it. Callers changed to match.
2946 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
2948 Cleanup for gdb-3.94 release final:
2950 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
2951 the .c files from vx-share and nindy-share, from the various
2952 macros, since they are not found via ALLDEPFILES.
2953 (SFILES): Add tm-i960.h.
2954 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
2955 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
2957 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
2958 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
2960 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
2962 * am29k-tdep.c: Add contribution line.
2963 (examine_prologue): Cache information about function prologues in
2964 the misc-function-vector to avoid lots of references over the
2965 serial line while examining instructions.
2967 * core.c (core_close): New function made from cleanup_core.
2969 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
2970 remote-vx.c, remote.c, target.c, target.h,
2971 Update target_ops vector to add attach, close, and load entries.
2972 Use add_syms_addr_command, not add_file_addr_command, for
2973 add_file. Break out close routine from existing code.
2975 * dbxread.c (really_free_pendings): Don't free pending_blocks;
2976 they are in an obstack.
2977 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
2979 (define_symbol): Add symbol type parameter; change callers;
2980 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
2981 it to influence the symbol class on the i960.
2982 (define_symbol): Swap LOC_CONST's into target byte order.
2984 * exec.c (exec_close): New function.
2985 (exec_file_command): Call it.
2987 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
2988 Fix byte order of frame pointer.
2989 (read_var_value): Result of 0 if var's value can't be found,
2990 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
2991 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
2992 (locate_var_value): Use read_var_value and use its lazy address
2993 as the location of the var's value. Lint.
2995 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
2998 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
2999 obsolete Intel versions in favor of vxgdb versions.
3000 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
3001 code dealing with byte order of values, which Intel did in host byte
3002 order rather than gdb-4's target byte order.
3003 (i960_frame_chain_valid): Move to nindy-tdep.c.
3004 (examine_prologue, skip_prologue, frame_find_saved_regs,
3005 frame_args_address, leafproc_return, saved_pc_after_call,
3006 pop_frame): Add vxgdb versions from Mark Fox.
3007 (examine_prologue, frame_struct_result_address): Add code
3008 to deal with the saved value of G13 (struct return address
3010 (frame_args_address): Modify Mark's version to prefer the
3011 saved value over the current value in the topmost frame.
3012 Cache result in the frame info to avoid performance hair in
3014 (print_fault): Add gdb960 code for printing faults.
3015 (_initialize_i960): Actually call check_host.
3017 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
3018 add stub routines. FIXME, these currently just return zero!
3020 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
3021 (attach_command): Call target_attach, not target_open, now.
3023 * infrun.c (normal_stop): Make global, not static, for vx_attach.
3024 (child_attach): Rename from child_open.
3025 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
3026 don't confuse it with a zero step_resume_break_address.
3028 * inftarg.c (child_detach): Eliminate inferior_pid test.
3029 (child_files_info): Clean up message a bit.
3030 (child_ops): Use child_attach, not child_open, to attach.
3032 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
3033 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
3034 findvar.c to here, since it depends on the contents of the
3035 shadow_contents of breakpoints, but keep if #if 0 since it is
3038 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
3041 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
3042 (ptype_command, display_command): Eliminate have_inferior_p and
3043 have_core_file_p in favor of target_has_stack or
3044 target_has_execution.
3045 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
3046 code for actually finding the values of arguments, though we still
3047 keep track of the maximum stack offset for use in printing unnamed
3048 arguments. Handle missing FRAME_ARGS_ADDRESS.
3050 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
3051 (struct nindy_regs): Define registers passed to/from nindy.
3052 (nindy_fetch_registers, nindy_store-registers): Translate between
3053 nindy and GDB formats for the registers.
3054 (dcache_init): Statically allocate the cache, since it was being
3055 allocated by a malloc that was never freed anyway.
3056 (nindy_create_inferior): Error, not core dump, if no exec file.
3057 (nindy_before_main_loop): Use target_load, not target_add_file.
3059 * remote-vx.c (net_load): Specify large timeout for load
3060 requests. Allow user to break out with INTERRUPT.
3061 (net_break): Remove useless code, clean up. Change callers.
3062 (parse-args, skip_white_space, find_white_space): Clean up arg
3063 parsing to cope with quoted strings.
3064 (net_wait, net_quit): Never call error, just return status.
3065 (vx_read_register, vx_write_register): Cleanup status checking.
3066 #ifdef the code based on which CPU we are using (960 or 68k),
3067 FIXME, this should be completely general but it isn't yet.
3068 (vx_xfer_memory, vx_resume): Cleanup status checking.
3069 (vx_run_files_info): Improve message.
3070 (vx_load_command): Renamed from vx_add_file_command. Allow load
3072 (net_ptrace): Remove unused routine.
3073 (vx_wait): Adopt code from vxgdb960 to cope with broken
3074 connections to target machine and prompt to disconnect. Remove
3075 debug printouts. Map some EVENT_'s to SIGnals.
3076 (add_symbol_stub, vx_open): Print names of object files we found,
3077 and "ok" if we read their symbols OK. Clarify output in general.
3078 (vx_attach, vx_detach, vx_kill): Add these commands.
3079 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
3080 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
3081 "info files" output, and create_inferior, since we already have
3084 * stack.c (frame_info): Replace Frame_unknown with 0.
3085 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
3086 (return_command): Pop until the PC matches as well as the FP,
3087 so it works even if the FP is shared with another function,
3088 as in "frameless" or "leaf" procedures.
3090 * symfile.c (load_command): renamed from add_file_target_command.
3091 (add_syms_addr_command): renamed from add_file_addr_command.
3092 (add_syms_command): Stub to call target_add_syms.
3093 (_initialize_symfile): Change command names and descriptions,
3094 add-file => add-syms, and load from alias to its own command.
3096 * target.c (kill_or_be_killed, maybe_kill_then_attach,
3097 maybe_kill_then_create_inferior): Default for attempts to start
3098 a process, if one is already running, is to ask about killing
3099 it and retry if yes.
3100 (upstack_create_inferior): #if-0 it, strata obsolete it.
3101 (push_target, unpush_target, pop_target): to_close() a target
3102 before unstacking it.
3103 (target_info): Renamed from target_files_info.
3104 (_initialize_targets): Rename "i files" as "i target", accessible
3107 * target.h: Improve comments about the target_ vectored routines.
3109 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
3110 Convert commenting style to standard GNU style.
3111 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
3112 (SKIP_PROLOGUE): No longer a no-op.
3113 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
3114 (*_REGNUM): Sort register numbers.
3115 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
3116 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
3117 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
3118 are now 10 byte extendeds, not 8 byte doubles.
3119 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
3120 for nindy versus vxworks targets. FIXME, this should possibly go
3121 in the target vector.
3122 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
3123 frame_saved_regs and arg pointer with each frame.
3124 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
3125 (FRAME_ARGS_ADDRESS): Use cached result.
3126 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
3127 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
3128 (PRINT_RAMDON_SIGNAL): Call print_fault.
3129 (POP_FRAME): Now works.
3131 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
3132 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
3133 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
3134 (ADDITIONAL_OPTION_HANDLER): use target_load, not
3137 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
3138 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
3140 * valarith.c (value_subscripted_rvalue): Avoid handling
3141 floats and doubles specially; it gave alignment errors. Lint.
3143 * valops.c (value_of_variable, value_of_this): Error if unknown
3146 * valprint.c (print_floating): Bcopy rather than pointer-deref,
3147 to avoid alignment problems.
3148 (value_print): Handle unknown value address.
3149 (cplus_val_print): Two args are ignored; remove them. Change caller.
3150 (val_print): Use unpack_long rather than pointer-deref.
3153 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
3154 to avoid alignment problems.
3155 (value_being_returned): Error if return value unknown.
3156 (set_return_value): Add bogosity warning, FIXME. *
3158 * TODO: A woman's work is never done.
3160 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
3161 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
3162 Add ieee-float.o to OBS.
3163 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
3164 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
3165 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
3167 Changes to generalize the VxWorks RPC protocol slightly, to handle
3168 i960 as well as 68000.
3170 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
3171 * vx-share/reg.h: Produce i960 regs #ifdef I80960
3172 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
3173 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
3174 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
3175 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
3176 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
3177 so they will move in target byte order rather than network
3178 byte order (happens to be the same).
3180 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
3182 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
3184 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
3187 Add contribution lines to various files, showing where they
3190 * breakpoint.c (break_insn, check_break_insn_size,
3191 read_memory_nobpt): Remove to mem-break.c.
3193 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
3196 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
3197 entry has bad register number. This change is not
3198 tested in this release, FIXME.
3200 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
3203 * value.h: Force value's contents field to be aligned to hold
3204 at least a double or a long long (if supported). This avoids
3205 doing bcopy's in and out of the contents field.
3207 (step_1): Avoid coredump under obscure circumstances when we
3210 * symtab.h (misc_info): Add field to misc function vector for
3211 any kind of cached information the target code desires. AMD
3212 29000 uses this to avoid repeating examine_function_prologue's.
3214 * coffread.c: Lint. Remove static symfile, read_section_header.
3215 core.c (have_core_file_p): Lint: remove.
3216 expprint.c (print_subexp): Lint.
3217 infptrace.c, valops.c, valprint.c: lint.
3219 Roll in changes from vxgdb-5.0.1:
3221 * symtab.h: Comment byte order of each address class. Add
3222 LOC_LOCAL_ARG for frame-relative args (960).
3223 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
3224 symtab.c, symmisc.c: ditto.
3226 * infrun.c (init_wait_for_inferior): Clear stop_signal.
3228 * remote.c (remote_resume): Error if resume with a signal.
3230 * symfile.c (prim_record_misc_function): Clear misc_info.
3231 (fill_in_vptr_fieldno): Check stub type of arg.
3233 * valops.c (value_cast): Avoid looking up names of types whose
3234 name we don't know, to prevent coredump. Sun CC produces typedef
3235 rtx and the name of *rtx is zero...
3237 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3239 Roll in changes from final AMD 29000 port (Tiemann).
3241 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
3242 for ../include/a.out.encap.h. This might not work now that BFD
3243 is separately compiled. Instead, BFD support for encap will have
3244 to translate machine type 29k into the right COFF_MAGIC.
3246 * infcmd.c: Remove references to inferior_pid that aren't used
3247 in actual ptrace calls; use target_has_execution, etc.
3248 (have_inferior_p): Remove function.
3249 (program_info): Print target info rather than "process number";
3250 avoid gratuitous messages unless from_tty.
3251 (run_stack_dummy, finish_command): Set proceed_to_finish.
3252 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
3253 main.c: Lint. Lose have_inferior_p().
3254 inferior.h (have_inferior_p): Remove, lint.
3255 (proceed_to_finish): Add flag to ask that all regs be saved
3256 by normal_stop, for the few commands that need it, speeding up
3257 serial I/O. Add comments to stop_registers.
3259 * remote-eb.c: Remove newline from breakpoint message we grep
3260 for. Never time out when running the user program.
3264 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3266 Roll in changes from vxgdb-5.0.1:
3268 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
3269 symbol in its raw form, we are processing an unlinked ".o" file.
3270 See if the target environment has assigned it an address, using
3271 target_lookup_symbol (VxWorks does), and enter it into the symtab
3274 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
3275 68k versions for a simpler version that assumes zero FP at bottom.
3276 Fixes bug of truncated stack reports.
3278 * target.h (target_lookup_symbol): Define this routine's args
3279 and result, finally.
3281 * target.c (nosymbol): Default routine for target_lookup_symbol.
3282 (target_default): Default lookup_symbol and call_function too.
3283 (files_info): Only print has_all_memory warning if a non-dummy
3286 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
3287 vx_convert_from_virtual): If target does not have floating point,
3288 zero register "values", and avoid doing cross-net conversions.
3289 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
3290 (vx_open): Rearrange code that attaches to target and reads
3291 symbols for all loaded modules, to work if some of the modules
3292 are not accessible. Add symbol_stub() and add_symbol_stub()
3293 as callbacks from catch_errors(). Allow connect attempt to be
3294 interrupted painlessly with ^C (FIXME, there are still some bugs
3295 if the interrupt happens during symbol reading.). Print
3296 final message with puts_filtered, since symbol messages are
3301 * main.c (catch_errors): Only print errstring if non-null.
3302 (command_loop): Avoid an ioctl per command to test ISATTY.
3304 * remote-vx.c (net_load): make static; avoid sophomoric msg.
3305 (vx_xfer_memory): Return correct result!
3306 (vx_files_info): Indicate whether target has float or not.
3307 (vx_lookup_symbol): Complain, not error, if target gone.
3308 (vx_open): Print "Connected" msg before disabling immediate-quit.
3309 [FIXME: lookup_symbol and vx_open changes need testing.]
3311 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
3312 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
3313 contributor lines and update copyrights to 1991.
3315 Changes from an attempted H-PUX host port:
3317 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
3318 defines PT_ATTACH and PT_DETACH but not PT_KILL.
3319 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
3320 * remote-vx.c: include <sys/time.h> for HPUX.
3321 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
3322 "core_file_command" routine to BFD regime. May not work yet.
3324 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
3326 * xgdb.c: Replace X10 version with some VJ version.
3327 (FIXME: Its copyright assignment is not on record.)
3328 * xgdb.c: Update include files to X11R4 (Xaw crud).
3329 (xgdb_display_source, create_text_widget): fix call to
3330 get_filename_and_charpos. Rewack source window stuff for X11R4
3331 (gleaned from include files, and "nm's" of binary libraries, since
3332 I had no doc available).
3333 (append_selection, append_selection_word): Disable with FIXME
3334 since R4 changed interface here.
3335 (create_buttons): Add back the old set of buttons.
3336 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
3338 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
3339 Roll VERSION to 3.94 (not yet final though).
3341 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3343 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
3344 obstack_int_grow, obstack_int_grow_fast): Eliminate
3345 cast on left of assignment, which gives MIPS cc fits and is
3348 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
3349 F_ALIAS. Use printf, not fprintf, when not passing a file
3351 (compare_opcodes): Check that identical instructions have
3352 identical opcodes, complain otherwise.
3354 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
3355 was reported by Roland McGrath.
3356 (unimp): Only match if exactly zero instruction. (Roland)
3357 (branches and traps): Generate all variations of these
3358 instructions with macros, based on a single call that defines
3359 each condition name and its binary representation.
3360 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
3362 * valprint.c (val_print_fields): Take, and use, format parameter.
3363 This means that "p/x struct" again prints the elements in the
3364 desired format. Changed callers.
3366 * stack.c (frame_info): Use filtered output, and indicate wrap
3367 points. Remove kludgy formatting designed to avoid line wrap.
3369 * utils.c (wrap_here): If the line is already full (because
3370 we had printed a long indent or long wrapped string), do an
3371 immediate newline-and-indent.
3373 * m68k-pinsn.c (print_insn_arg): Bugfix from
3374 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
3375 instruction is incorrectly disassembled as bkpt #8.
3377 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
3378 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
3379 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
3380 and then will dump core (sometimes). I traced it back to an
3381 uninitialized symfile_name in psymtab_to_symtab.
3382 (const_vol_complaint): Add quotes to message.
3383 (define_symbol): Only believe line number if gcc_compiled.
3384 Avoid allocating symbol if we will not return it.
3386 Add target strata support so that newly established targets go
3387 into their right place in the target stack (e.g. a new exec file
3388 doesn't wipe out the ability to access the running process).
3390 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
3391 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
3392 and initialize it properly in all the targets.
3394 * target.h: Document strata. Change return type of push_target.
3396 * target.c (nomemory): new function for dummy memory access.
3397 (tcomplain): Rename complain, now also used in symfile.c.
3398 (push_target): Push targets within strata. New return value shows
3399 whether new target is on top of stack or not. Always keep dummy
3401 (target_files_info): Ignore dummy target.
3403 * core.c (core_open): Warn user, and skip accessing file, if the
3404 core target is not the topmost target in the stack.
3405 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
3408 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
3409 target_ops, it doesn't belong there since we have no regs there.
3410 Change name of target from machine => memory to clarify.
3412 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
3414 * Freeze version 3.93 for release.
3416 * Makefile.dist: Handle vx-share and nindy-share subdirs
3417 properly when building gdb.tar.Z.
3419 * symtab.c: lint; add no_symtab_msg to consolidate the messages
3420 printed in various places, so I could change just one copy.
3422 * dbxread.c, coffread.c: Change references to bfd->iostream
3423 to cast to FILE *, now that BFD avoids needing types defined
3424 in other header files.
3426 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3428 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
3429 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
3430 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
3431 (actually gcc -Wall).
3433 * dbxread.c: Remove first_global_sym, last_global_sym, since
3434 they are never referenced.
3436 * defs.h (baud_rate): Declare.
3437 main.c: Define it, and add the -b option to set it.
3439 * gdb-int.texinfo: Add text on how to define a new host or target
3440 architecture, prompted by Per Bothner's questions about MIPS
3443 * gdb.texinfo: Document "complaints". Change doc of -q since
3444 gdb no longer prints the copyright and blurb if you specify a file
3445 name to be debugged (just like Emacs). Add doc for Nindy-specific
3446 command line flags for specifying target serial port and such.
3447 Update copyright to 1991.
3449 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
3450 has taken over for us the job of ripping up executable files. The
3451 crud caused Per Bothner's port to not compile.
3453 * infrun.c (normal_stop): Avoid printing "Program exited
3454 normally" if we are in batch mode. This allows a GDB which
3455 executes a program on a target system, to behave like a Unix
3456 command (input from stdin, output to stdout, no extraneous
3459 * main.c (main): Allow additional machine-dependent command line
3460 options to be specified with the ADDITIONAL_OPTIONS,
3461 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
3462 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
3463 processing to occur just before the main loop with
3464 BEFORE_MAIN_LOOP_HOOK.
3465 (main): If a "core file" argument is specified, and it is not a
3466 core file, try it as a process ID to attach.
3467 (symbol_completion_function): Attempt to cope with
3468 "show screen-" TAB, not very successfully. This needs more work,
3470 (batch_file): New function, returns whether we are reading
3471 commands from an interactive tty on stdin, or from somewhere else.
3472 Called by normal_stop since it doesn't get from_tty passed down
3473 to it like many commands do.
3475 * remote-nindy.c: Handle command line options for nindy
3477 (nindy_before_main_loop): Prompt user for tty name if they
3478 don't specify it before getting to the interactive command loop.
3480 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
3481 and -r command line options. Also add hook before main loop
3482 to make it easy to specify a tty.
3484 * TODO: More things to do, one done.
3486 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
3488 * dbxread.c: Make complaint() calls pass pointer, not struct.
3489 Add complaints about badly formatted C++ type information
3490 (const/volatile indicator, and parse errors resulting in
3491 error_type). Fix C++ virtual member fn comment.
3492 (read_struct_type): Avoid bumping pointer if we got a parse
3493 error; this prevents our walking beyond the end of a string.
3494 Terminate loop on null char as well as semicolon.
3495 (process_one_symbol): Fix the LBRAC fix so that it uses the
3496 last previous SLINE, FUN, or SO record's PC address. C++ debug
3497 symbols did not have SLINE records in a useful order compared
3498 to the LBRAC records.
3499 (define_symbol): Handle "catch" records.
3501 * symtab.c (check_stub_type): Added new complain
3502 `stub_noname_complain' and added a consistency check to
3503 keep the debugger from crashing when finishing from an
3504 exception frame. A real fix will be needed later.
3506 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
3508 * infcmd.c (attach_command): Make global.
3510 * Makefile.dist (REMOTE_OBS): Make these compile by default,
3511 but make them easy to comment out. Perhaps later they should
3512 be enabled by what CPU you configure for? FIXME.
3513 (VERSION): Roll to 3.93.
3514 (pinsn.o): Remove rule for obsolete file.
3515 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
3517 Run down a problem that manifested by printing the wrong function
3518 name in stack traces of read_ofile_symtab. Turned out that the
3519 problem was the SunOS 4.1.1 (and previous) C compiler outputs
3520 the LBRAC symbol with an address in the *data* segment, which
3521 blew our binary search through the blocks.
3523 * dbxread.c: Use the complain() facility consistently to bitch
3524 about problems in the symbol file we are reading.
3525 (finish_block): Add code to check the nesting of the blocks;
3526 complain and Procrust them to fit if wrong.
3527 (make_blockvector): Check the order of the blocks, complain
3528 [but don't cope] if wrong.
3529 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
3530 symbols to be sure their PC value is greater than the last SLINE
3531 (line number) symbol we've seen, complaining and adopting the
3532 SLINE PC value if wrong.
3534 * symfile.h (struct complaint, complaint_root, complain,
3535 clear_complaints): Add.
3536 * symfile.c (complain, complaint_root, clear_complaints): Add
3537 facility to deal with non-fatal complaints and to regularize their
3539 (symbol_file_add): Clear complaint counters to allow new complaints.
3540 (initialize_symfile): Add 'set complaints' and 'show complaints'.
3542 * dbxread.c (dbx_symfile_read): Remember the address and size
3543 of the string table for the main symbol file, so we won't read it
3545 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
3546 to avoid reading the string table yet again. Lint.
3547 (throughout): Improve filtered output, including word wrap.
3548 (read_range_type): Improve Bothner's fix to handle other types too.
3550 * utils.c: Improve line wrap implementation. Handle unlimited
3551 width by making chars_per_line unsigned.
3552 (puts_filtered): New, easy, function.
3554 * defs.h (puts_filtered): add.
3556 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
3557 call the identical sort_symtab_syms() in symfile.c instead.
3559 * expread.y: Suggest the `file' command rather than `symbol-file'.
3561 * command.h (enum var_types): Add zinteger for seroable
3563 * command.c (do_setshow_command): Handle var_zinteger. Restructure
3564 nested if's into a switch.
3566 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
3567 we did not stop because of a breakpoint (it must have been for
3568 some other reason, like a "stepi"), so don't print anything.
3570 * symtab.c: Include <sys/types.h> all the time. Now that BFD
3571 doesn't include <sys/types.h>, old SunOS's require it for
3574 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
3576 A test port of gdb-3.92.6 to the Sony NEWS.
3579 Don't normally link in remote- or vx stuff.
3580 Some of it doesn't compile, and it wastes space for 99% of the users.
3581 Remove reference to no-longer-used HAVE_VPRINTF.
3582 Fixed BFD_DEP typo to BFD_DIR.
3584 Fix cast in arg to bfd_h_getlong.
3585 Make char *prefix be const.
3586 Fix how certain range types are mapped into builtin unsigned int types.
3588 Remove 2 #includes. They cause errors (on Sony, at least),
3589 and aren't needed (they wern't in earlier versions).
3591 print_address_symbolic should never demangle labels
3592 (since it prints *assembler-level* labels).
3594 [This was superseded by the change to printcmd below.]
3597 Add some "volatile" return types to avoid warnings.
3598 If MISSING_VPRINTF add vprintf function and not just macro
3599 (since vprintf is used in printcmd.c).
3601 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
3602 (The latter isn't grokked by some PCC-based compilers.)
3604 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
3606 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
3607 * nindy-share/coffstrip.c
3608 Added some forward declarations (otherwise, gcc complains
3609 about implicit extern redefined as static).
3611 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
3613 Changes inspired by Per Bothner:
3614 * printcmd.c (print_address_symbolic): Take additional parameter
3615 specifying whether to demangle.
3616 (print_address): Pass in asm_demangle to control demangling.
3617 (print_address_demangle): New fn, takes explicit arg to control
3619 * utils.c: Add new vars demangle and asm_demangle, and let them
3621 (fputs_demangled): If !demangle, just print the argument.
3622 (fprint_symbol): If !demangle, just print raw symbol.
3623 * valprint.c (val_print): Call print_address_demangle rather than
3624 print_address, to cause demangling to depend on the global
3625 rather than assembler-level demangling setting.
3626 * WHATS.NEW, gdb.texinfo: Document.
3628 * main.c (show_command): Show all settings if no arg.
3629 (initialize_main): Make "info set" the same as naked "show".
3630 * command.c (cmd_show_list): Handle prefix commands in the
3631 list, and print the name of the setting as well as its English
3632 description and value.
3634 Allow gdb functions to specify where a line should wrap if it
3635 exceeds the size of a terminal line. Use it to make the output
3637 * utils.c (set_screen_width_command): New fn, mallocs a buffer
3638 of the right size when screen width changes.
3639 (set_screensize_command, screensize_info): Remove #if 0'd fns.
3640 (wrap_here): New fn, indicates a point in the output where we
3641 should wrap the line rather than just letting it overflow at a
3643 (fputs_filtered): Implement wrapping.
3644 (n_spaces): New fn, returns a pointer to N spaces.
3645 (print_spaces_filtered): Use n_spaces.
3646 * defs.h (n_spaces): Declare.
3647 * stack.c (print_frame_info): Wrap with 4-space indent after
3648 fn name and before filename and line number.
3649 * printcmd.c (print_frame_args): Wrap with 4-space indent
3650 before each argument name is printed.
3651 * valprint.c (value_print): Wrap with no indentation before
3653 (val_print_fields): Wrap with indentation relative to nesting
3654 level before each field name.
3655 (val_print): Wrap with nesting indentation before array elements.
3656 * command.c (do_setshow_command): Avoid extra newlines,
3657 wrap with 4-space indent around values printed, end with period.
3658 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
3660 * breakpoint.c (breakpoint_1): Implement addressprint for
3661 "info breakpoints" display. Change file name and line number
3662 format to " at file:nnn" rather than " (file line nnn)".
3663 * gdb.texinfo: Document.
3666 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3668 Frozen for gdb-3.92.6 release.
3670 README, WHATS.NEW: Update for 3.92.6 release.
3672 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
3673 coffread.o from configs since it is now built by default.
3674 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
3675 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
3676 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
3677 from configs since it is now built by default.
3679 Makefile.dist: Update for release 3.92.6. Handle files that
3680 have been moved to ../include, ../getopt, or ../bfd. Add
3681 saber.suppress and tests directory. Add config.status to
3682 the release (it will say "none").
3684 coredep.c: Minor formatting fixes.
3686 These changes were made in early December but only checked in now:
3687 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
3688 nindy-share/nindy.c: lint
3689 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
3690 register values coming back from the target; we store values
3691 in target byte order everywhere.
3693 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
3695 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
3697 * valprint.c (cplus_val_print, val_print_fields): New functions,
3698 which print C++ objects. They conspire to avoid printing a
3699 virtual base class more than once, following all the twists and
3700 turns of C++ virtual base rules.
3701 (val_print): Call the above rather than do it by hand.
3703 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
3704 symbol file, not for added files like shared libs. This really
3705 needs to be generalized to a timestamp per file.
3707 * core.c (cleanup_core): Avoid coredump if no core file.
3709 * config.gdb: Accept -host or -target in place of +host or
3712 * coffread.c (find_linenos): Avoid desupported BFD interface
3713 to line numbers. We still read them manually rather than using
3714 BFD's "generic" features.
3716 * gdbrc.tex, threecol.tex: Add GDB reference card and its
3718 Makefile.dist: Add refcard to OTHERS list for creating tar files.
3720 * Makefile.dist: Eliminate use of $< in explicit targets.
3722 * readline/Makefile: Use $< rather than $*.c, which does not
3723 include the VPATH in GNU Make.
3725 * tconfig/i960-bout, tconfig/i960-coff: These are identical
3726 copies of tconfig/i960, added for global configuration
3727 compatability. All i960 versions can read both coff and b.out.
3729 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
3730 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
3733 * TODO: Think of more things to do.
3735 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
3737 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
3738 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
3739 64-bit float conversion.
3741 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
3742 equivalent to sun?os4 so global config works.
3744 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
3746 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
3748 * main.c: Only declare linesize once; declare pagesize not at
3749 all, since it is never used.
3750 (main): Clear newly allocated line before it is used.
3752 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
3754 Further stabilization for the Intel 960.
3756 * Makefile.dist: Parameterize the location of the "include"
3757 and "bfd" directories, as well as "getopt". Add symfile.c.
3758 Link in both dbxread and coffread. Fix up "make depend" to
3759 rewack the locations of include, bfd, and getopt in its output.
3761 * README: Document moving include files, improve some of
3764 * coffread.c: Move common code out to symfile.c. Change
3765 symbol_file_command style interface to use new *_symfile_init
3766 and *_symfile_read interface under BFD. Use BFD internal
3767 info to locate line table, symbols, etc.
3769 * core.c (core_fetch_registers): Rename to get_core_registers
3770 to avoid confusion with fetch_core_registers.
3771 (register_addr): Move to coredep.c, which is already machine
3772 dependent. This leaves core.c pretty clean of dependencies.
3774 * coredep.c (register_addr): Accept this routine from core.c.
3776 * dbxread.c: Move common code (with coffread.c, etc) into new
3777 symfile.c. Each psymtab now contains a pointer to the
3778 format-dependent function that knows how to read it in. Make
3780 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
3781 (process_one_symbol): Add code to complain about a "compiler bug
3782 we muzzle here", if we actually see it.
3784 * eval.c (evaluate_subexp): Insert missing "break" statements
3785 in code that determines whether a variable is an lvalue in
3786 memory, register, or whatever. I detected this via a compiler
3787 bug in which it *almost* mashed out the whole switch statement.
3789 * gdb-int.texinfo: Add minor sections on configuring gdb for
3790 release, and about the README file.
3792 * infcmd.c (registers_info): Fix formatting somewhat. Still
3793 not as pretty as before, but it handles byte swapping.
3795 * remote-nindy.c: If data cache routines are interrupted while
3796 waiting for the remote end, be sure that any uninitialized cache
3797 blocks are on the free list, not on the valid list!
3799 * symfile.h: Flesh out this header file with all the various
3800 routines and variables that have been merged in from dbxread.c
3801 coffread.c, and symtab.c to symfile.c.
3803 * symfile.c: New file, containing code common to dbxread.c,
3804 coffread.c, and some code from symtab.c. All generic code for
3805 reading symbol files should be in here now.
3806 (unrecord_misc_function): Remove unused function.
3808 * symtab.h: Remove file-reading things to symfile.h.
3810 * symtab.c: Remove file-reading things to symfile.c.
3812 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
3813 to decode i960 fault types.
3815 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
3816 target.c: Change type of the "resume" function from int to void,
3817 since its result was never used.
3819 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
3821 * main.c: Replace "stupid" with "caution"; you now "set caution
3824 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
3826 * infcmd.c (do_registers_info): Call val_print to deal with the
3827 byte order of the registers being printed. FIXME, this makes
3828 the formatting of the output uglier.
3830 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
3831 defined, call it for signals the debugger doesn't itself use.
3832 The i960 uses this for more detailed fault information.
3834 * remote.c (remote_open): If arg is null, print help rather than
3837 * sparc-xdep.c (register_valid): Avoid declaring size, since
3838 various modules will think of various sizes depending on the
3839 architecture of their tm-file. FIXME, we need protection against
3840 actually entering one of those modules, which would clobber
3841 storage if not for the target architecture compiled into gdb.
3843 * stack.c (up_command, down_command): Always print the frame
3845 (up_silently_command, down_silently_command): New commands
3848 * i960-pinsn.c (reg), i960-tdep.c: Lint.
3850 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
3851 more parameters than it used to.
3853 * findvar.c (registers): Increase slop to 256 bytes, which should
3854 protect us against even most RISC machines with large register
3856 (locate_var_value): Move declaration inside related ifdef.
3858 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
3859 throughout, to avoid throwing away buffered input from the board.
3860 (nindy_wait): Supply_register takes addr_of_value, not value.
3861 (i960_print_fault): Renamed from i80960_fault.
3862 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
3863 (nindy_store_registers): Avoid regs_changed stuff, just stuff
3865 (nindy_create_inferior): Don't bother to write PC_REGNUM since
3866 we can set the PC in the call to proceed(). Unpush nindy_ops
3867 before pushing it on top, to avoid message to user. Eliminate
3868 commentary from Unix machines that just misleads here.
3869 (reset_command): Fix error message to suggest target command.
3871 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
3873 Release 3.92.5 as frozen.
3875 Stabilize the merged release...with help from lint, Saber C,
3878 Everywhere: Add include files needed to declare return types
3879 of functions called.
3881 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
3883 * breakpoint.h: Add undeclared breakpoint functions, and some
3884 functions for display handling since I couldn't think of a better
3887 * breakpoint.c (insert_breakpoints): Make code for disabling
3888 shared library bkpts more likely to work. It's used when we
3889 rerun a program and stop before the shared library has been
3891 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
3892 cast from pointer, so it squeezes through catch_errors.
3893 (bpstat_stop_status): Fix logic broken some time ago. We now
3894 always create a bpstat if the stop address matches a breakpoint,
3895 even if we don't stop there -- just like the old code used to do
3896 before I got my fingers into it (sigh).
3897 (breakpoint_1): Print "ignore count" after "stop only if"
3898 condition, since that's how it actually works.
3899 (mention): Handle watchpoints as well as breakpoints.
3900 (watch_command): use set_raw_breakpoint and mention to do most
3901 of the work (and initialize all the fields!). Only pass one
3902 arg to parse_c_expression, since that's all it takes.
3904 * command.c (not_just_help_class_command): Rename arg to args
3905 since we ignore "unused argument" warnings on vars named "args".
3906 inflow.c (child_terminal_info): ditto.
3907 infptrace.c (kill_inferior): ditto
3908 main.c (catch_errors, version_info, quit_command, pwd_command,
3909 source_command, dump_me_command, editing_info,
3910 set_history_size_command, set_history, show_history,
3912 stack.c (locals_info): ditto
3913 target.c (target_files_info): ditto
3914 valprint.c (set_input_radix, set_output_radix): ditto
3916 * core.c: Remove old variables for handling core and exec file
3917 sections (data_start, data_end, stack_start, stack_end,
3918 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
3919 text_end, exec_data_start, exec_data_end, text_offset,
3920 exec_data_offset, data_offset, stack_offset). They're
3921 superseded the more general build_section_table and
3923 (get_exec_file): Mention the `file' command.
3924 (read_memory_check): Rename to memory_error, and only call it
3925 in the case of an actual error.
3926 (read_memory, write_memory): call memory_error.
3927 (core_fetch_registers): Register section name is ".reg".
3929 coredep.c: Remove a bunch of crud now that all this file does
3930 is pull the registers out of a core file.
3931 (fetch_core_registers): Rewrite to actually work, I hope.
3933 dbxread.c: Use a.out.gnu.h, not system a.out, now.
3934 Replace index() with strchr(). Remove all the pre-BFD macro
3935 definitions for accessing the symbol file.
3936 (struct dbx_symfile_info): Encapsulate the information that
3937 dbx_symfile_init needs to pass to dbx_symfile_read in this
3940 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
3941 dbx_symfile_discard): Rearrange symbol file reading to divide
3942 the format-specific part from the format-independent part,
3943 leaving the format-independent part such as file name expansion
3944 and opening in symtab.c. This replaces
3945 partial_symbol_file_open and partial_symbol_file_read.
3946 Symbol_file_read, add_file, add_file_target_command,
3947 add_file_addr_command move to symtab.c. Pass an explicit
3948 "mainline" flag for when reading the main symbol table, rather
3949 than relying on the offset address to be zero or nonzero.
3951 (dbx_symfile_read): Don't allow void *'s to be printed as
3953 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
3954 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
3955 macro" debug version really work.
3956 (read_dbx_symtab): Remove unref'd parameter inclink.
3957 Avoid swapping N_SLINE symbols, for speed.
3958 Merge N_TEXT!N_EXT case with the other external symbol
3959 definitions' case. Add comments.
3960 (start_psymtab): Allocate the symfile name in the psymtab on
3961 the psymbol_obstack, rather than using the caller's storage.
3962 (end_psymtab): Only allocate a dependencies list if there are
3964 (psymtab_to_symtab_2): Use BFD when reopening file to read
3965 its symbols for real.
3966 (read_struct_type): Add FIXME comments where it needs work
3968 (read_huge_number): Add FIXME about overflows.
3969 (read_range_type): Add FIXME about comparing a long to 1<<32.
3971 * coffread.c: Minor changes to move things closer to the new
3972 regime with symtab.c and dbxread.c Major work is still needed
3975 * exec.c (exec_file_command): Remove old variables (see core.c
3977 (xfer_memory): If memory transfer is right at the end of a
3978 section, don't lose.
3980 * findvar.c (get_saved_register): If value is in a real
3981 register, LVAL is lval_register, not lval_memory.
3983 frame.h: Declare print_sel_frame and record_selected_frame.
3985 gdb-int.texinfo: New file, for GDB internals documentation.
3986 Very simple, unformatted doc of cleanups is there for now.
3988 gdbcore.h: Remove obsolete variables that described a.out
3989 section addresses and offsets. (See core.c above.)
3990 Declare fetch_core_registers and registers_fetched.
3992 getopt.c: Declare char *alloca(); even on SPARC.
3994 infcmd.c (run_command): Call target_kill rather than
3996 (step_command, next_command, stepi_command, nexti_command):
3997 Declare from_tty parameter even though we don't use it.
3998 (run_stack_dummy): argument BUFFER is a char array, not
3999 a pointer to REGISTER_TYPE.
4000 (finish_command): using_struct_return needed a value *,
4001 not a struct symbol *.
4003 * infptrace.c (child_xfer_memory): To avoid dependency on
4004 where sections are in memory, try PT_WRITE_D and if that fails,
4005 try PT_WRITE_I. Most Unixes don't care which you use.
4007 * infrun.c (step_resume_break_shadow): Change to array to
4008 match other breakpoint shadow storage.
4009 (clear_proceed_status): Pass address of bpstat to
4010 bpstat_clear, not the bpstat itself.
4011 (child_create_inferior): FIXME comment about if the child
4013 (start_inferior): Remove old function.
4014 (child_open): Use target_kill rather than kill_inferior.
4015 (wait_for_inferior): Ditto.
4016 (insert_step_breakpoint, remote_step_breakpoint): Use
4017 new step_resume_break_shadow.
4019 * inftarg.c (child_wait): If all child processes die,
4020 pretend that the one being waited for exited with signal 42.
4022 * main.c (command_line_input): When scanning for comments,
4023 don't coredump on unclosed quotes.
4024 (quit_command): Use target_kill rther than kill_inferior.
4025 (_initialize_main): Rename class_user from "user" to
4028 * printcmd.c (print_command_1): Initialize "fmt" if no format
4029 is specified by the user.
4030 (print_frame_args): Only add to args_printed if we are
4031 actually fetching args from the stack (avoiding undefined
4033 (_initialize_printcmd): Remove bogus \{ from string.
4035 * remote-eb.c (eb_open): Avoid coredump on no argument.
4037 * remote-nindy.c: Bring out of Intel environment into new
4038 target environment. Remove all conditional compilation on
4039 I80960. Massive hacking throughout.
4040 (nindy_xfer_inferior_memory): New routine stolen from
4042 (nindy_create_inferior): New routine pieced together, probably
4043 not quite working yet.
4044 (nindy_ops): New target_ops struct for nindy.
4046 * remote-vx.c: Use write_memory rather than target_write_memory
4047 to get error checking.
4048 (vx_add_file_command, vx_open): Use symbol_file_add rather than
4050 (vx_create_inferior): Use target_terminal_ours...
4052 * signame.c (_initialize_signame): Always initialize, since
4053 we need the table for things other than psignal.
4055 * solib.c (solib_add): Use symbol_file_add, not add_file.
4056 (solib_address): Return boolean result rather than struct
4057 pointer which nobody else knows the type of.
4059 * sparc-tdep.c, valops.c: Use write_memory rather than
4060 target_write_memory, to get error checking.
4062 * stack.c (locals_info, catch_info, args_info,
4063 get_selected_block, frame_command, up_command): Use
4064 target_has_stack, rather than have_inferior_p or
4067 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
4069 * symfile.h: New file, defining the interface between the
4070 generic and object-file-specific symbol reading code.
4072 * symtab.c: Move generic symbol-reading interface to symtab.c,
4073 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
4074 table to map BFD targets to symbol-reading modules in GDB.
4075 Change index to strchr.
4076 (lookup_struct_elt_type): Use error() rather than hand-made
4077 simulations thereof.
4078 (lookup_partial_symbol): Speedup slightly when length == 0.
4079 (symbol_file_add): New function.
4080 (symbol_file_command): Call it.
4081 (symfile_open, symfile_init): New function.
4082 (add_file_target_command, add_file_addr_command): moved from
4085 * target.c (target_command): use target_kill.
4087 * target.h (target_files_info): Don't declare, never called
4090 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
4091 files to determine stack end address.
4093 * valarith.c (value_x_binop, value_x_unop): Change error message
4094 to be more useful. Pass proper argument to value_struct_elt.
4096 * valops.c (value_assign): FIXME comment that long long
4097 bitfields will break here.
4099 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
4100 Update `make saber_gdb' to work better.
4102 * TODO: A woman's work is never done.
4104 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
4105 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
4106 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
4107 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
4108 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
4109 valops.c, valprint.c, exec.c: Lint.
4112 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
4114 Continuing Intel 960 port merge of GDB.
4116 * Makefile.dist: Merge i960 "nindy-share" files. Rename
4117 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
4118 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
4119 Wack over "make depend" so it handles files in subdirectories
4120 vx-share, nindy-share, bfd, and in the current directory.
4122 * blockframe.c (get_prev_frame_info): Remove fatal error
4123 if stack not defined.
4125 * core.c (core_open, core_detach): New functions that handle
4126 the old "core-file" command as "target core" and "detach" instead.
4127 (core_file_command): Call them.
4128 (core_xfer_memory): Use common routine xfer_memory.
4130 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
4131 dbxread now uses bfd for everything but symbol reading itself.
4132 BFD internals are used to drag out the relevant file offsets.
4133 (partial_symbol_file_open): Change args all around for BFD.
4135 * symtab.c: Rename "value" to "val" everywhere, so we can
4137 (symbol_file_command): New command, moved from dbxread.c
4138 and coffread.c. It uses BFD to read the file, then vectors
4139 based on its type, to dbx or coff symbol readers.
4140 * symtab.h: Extern a few vars for symbol_file_command.
4142 * target.h: Breakpoint takes a char * save area, not a char **.
4144 * valprint.c (val_print): When unpacking bitfields, offset
4145 the address in gdb of the value, if it is declared with a shorter
4146 type. Remove the last "runtime kludge test" of host byte order.
4148 * utils.c: Remove old my_bfd_read routine.
4150 * stack.c (frame_info): Use target_has_stack. Print program counter
4151 register's actual name rather than "pc", since it's called the
4152 "ip" (instruction pointer) on the i960 (sigh).
4154 * target.c (target_command): Add command for selecting a target
4155 type and calling its open routine. This is used for initiating
4156 communication with a particular target, in a generic way.
4158 * tm-i960.h: Update for modern gdb. Remove semicolons from
4159 various macros. Handle reading struct return convention, and
4160 error-out attempts to return structs with the "return" command.
4161 Be sure gdb doesn't think we know how to call functions in the
4164 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
4165 to i960_xxx in lower case.
4166 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
4167 not being defined yet.
4169 * remote.c (remote_open): Call start_remote to initialize
4170 wait_for_inferior during open.
4171 (remote_xfer_inferior_memory): Return length written rather
4174 * remote-vx.c (target_command -> vx_open): Use new generic
4176 * remote-eb.c, inftarg.c, exec.c: ditto.
4178 * infrun.c: Fix comments.
4179 (attach_program -> child_open): Use new generic target command.
4180 (wait_for_inferior): Clear saved register values before target_wait,
4181 so target_wait can set some of them if convenient.
4183 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
4184 Return success indicator, not void.
4185 (child_xfer_memory): Avoid fetching initial word if we'll
4186 overwrite it anyway.
4188 * infcmd.c (attach_command): Use new generic target open routine.
4189 (_initialize_infcmd): Update doc on attach and detach commands.
4190 (do_registers_info): Merge in a byte-order problem as a FIXME
4193 * findvar.c (find_saved_register): Avoid problem in current frame.
4194 (read_relative_register): Ditto.
4195 (write_register): Convert byte order on the way out.
4197 * exec.c (file_command): Add.
4198 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
4199 (xfer_memory): Common function between core_xfer_memory and
4201 (exec_xfer_memory): Use it.
4203 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
4205 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
4206 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
4207 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
4209 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
4211 Merge Intel 960 port of gdb, continuing...
4213 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
4214 symbol_file_command): Pass from_tty arg to hush 'em up.
4216 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
4217 Add magic numbers for 960 COFF format.
4219 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
4221 Merge Intel 960 port of gdb, from Intel "1.2" release.
4223 CHANGE_LOG entries from their port, which was based on
4226 Thu Sep 6 11:02:22 PDT 1990
4227 Remove temp file if download is interrupted.
4229 Wed Aug 1 09:08:33 PDT 1990
4230 Now uses binary protocol to talk to NINDY.

4232 Times out after 5 seconds when trying to talk to NINDY.
4234 Tue May 29 12:54:49 PDT 1990
4235 Added variable baud rate (-b switch).
4236 Source code reorganization.
4238 Thu Apr 26 11:09:55 PDT 1990
4239 More cleanup of batch mode; specifically, execute "-s", "-e", and
4240 "-se" switches as soon as they are encountered on the invocation line.
4242 Fri Apr 20 13:47:15 PDT 1990
4245 Thu Apr 19 09:54:28 PDT 1990
4246 Add 'reset' command.
4248 Wed Apr 18 09:48:07 PDT 1990
4249 After opening remote tty, wait for 1 second to go by without input
4250 from it before trying to talk to NINDY (fixes problems with the
4251 Heurikon HK80/V960E).
4253 Mon Apr 4 16:33:05 PDT 1990
4254 Some output was not being suppressed in 'batch' mode.
4256 Thu Mar 22 15:31:11 PST 1990
4257 Ask user if old symbol table should be deleted when new file is
4260 Allow user to run a program downloaded before gdb960 was brought up.
4262 Correct "exec-file" help message for i80960 context.
4264 Correct bug in calculating user space address: could occasionally
4265 corrupt user program.
4267 Make sure to zero low-order bits in rip's because of bug in 960CA
4268 A-step part: could cause operation faults when "next"ing across
4271 Correct bug that made it impossible to get source line numbers for
4272 code loaded at addresses higher than 0x7fffffff.
4274 Wed Jan 10 12:43:22 PST 1990
4275 Open remote tty for exclusive use.
4277 Fri Jan 5 12:14:42 PST 1990
4278 Correct disassembly (CA manual was right after all):
4279 opcode for sysctl is 0x659
4281 Mon Oct 23 12:03:04 PDT 1989
4282 Use G960BASE and G960BIN environment variables to find 'sx' utility.
4284 Mon Oct 16 14:15:09 PDT 1989
4285 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
4287 Mon Oct 2 15:56:31 PDT 1989
4289 Added 960CA disassembly support.
4291 To simplify maintenance:
4292 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
4294 - eliminated opcode.h: incorporates tables into i960-pinsn.c
4295 - moved 960-specific routines from i960-pinsn.c to i960-md.c
4296 - made disassembly interface identical to that in gdmp960.
4300 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
4302 * target.h: Allow targets to stack. Add target_has_memory,
4303 _registers, etc. Restructure memory access and "info files"
4304 to walk the target stack.
4305 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
4306 target.c: Change tables to match target.h.

4312 * remote-vx.c: New memory regime, new info files. Now use
4313 separate targets for VxWorks attachment to machine, and
4314 actually running a process under VxWorks, since one has
4315 stack & execution & regs and the other doesn't.
4316 * remote.c: New memory regime, new info files.
4317 * sparc-xdep.c (fetch_core-registers): New memory regime.
4318 * target.c: New routines and support for stacked targets,

4361 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
4363 Massive changes to wall off the remote-debugging interface
4364 behind a function vector. The port to handle VxWorks targets
4365 is also part of this.
4367 All files: Replace references to renamed functions,
4368 remove references to remote_debugging, remove references to
4369 have_include_file, have_core_file in favor of target_has_stack,
4370 target_has_memory, etc.
4372 * Modularize the breakpoint interface.
4373 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
4374 a breakpoint instruction.
4375 breakpoint.c: struct breakpoint's shadow_contents now sized as
4377 (insert_breakpoints): Vector to target to install breakpoints.
4378 (remove_breakpoints): Vector to target here too.
4379 Remove REMOTE_SA_SPARC kludges and other remote_debugging.

4381 the single-step breakpoints.
4382 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
4383 New file, contains routines to insert and remove breakpoints by
4384 reading out the old contents and later replacing them. This is
4385 how ptrace breakpoints work, and many remote systems as well.
4387 * tm-vxworks68.h: New config file, overrides a few things for
4388 Wind River's preferences.
4390 * target.h: New file, for transfer vector used to talk to the
4391 inferior (child, attached, core, exec, remote, etc). All accesses
4392 to the thing being debugged should come through these vectors.
4393 target.c: New file, routines to handle transfer vector.
4394 (various files): Add transfer vectors XXX_ops for the various
4395 targets and pseudo-targets (core files, etc) we support.
4397 * breakpoint.c (bpstat_stop_status): Further explorations of
4398 watchpoints and why things don't work all the time.
4399 (bpstat_alloc): New fn to allocate a bpstat and chain it.
4401 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
4402 the local gdbinit if it doesn't already have it.

4405 Allow core debugging without exec file.
4407 * dbxread.c (free_and_init_header_files): Merge two fns.
4408 (end_symtab): Free named symbol table when a new version comes in.
4409 (read_dbx_symtab): Relocate all kinds of symbols with base
4410 address. First step toward handling different text, data, bss
4412 (add_file_addr_command): Renamed add_file_command.
4413 (add_file_command): Vector to remote handler.
4414 Add "load" as an alias for "add-file" command.
4416 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
4417 non-returning functions.
4419 * exec.c: Add exec_ops, and push it as a target when an exec
4422 * infcmd.c (run_command): Pass executable file name and arg list
4423 separately when starting an inferior. Permit "run" when no exec
4424 file is specified, for VxWorks.
4425 (detach_command): Move to child_detach in inftarg.c.
4427 * inftarg.c: New file. Unix-child-specific routines, and the
4428 child_ops structure.
4430 * inferior.h (registers): Export "registers" as the way for
4431 target dependent register handlers to find gdb's local copy of
4432 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
4433 since it is now used by places that want wait_for_inferior to
4434 handle the grunge but want to see every trap from the inferior.
4436 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
4437 Eliminate remote_debugging hooks in terminal handling.
4439 * infrun.c: Replace start_inferior with child_create_inferior.
4440 Move all the hair of Unix shells and ptrace idiosyncracies into
4441 child_create_inferior, so remote handlers don't have to deal.
4442 Remove running_in_shell. Rename stop_after_attach to
4443 stop_soon_quietly, and use it in a few other places where we want
4444 to just call wait_for_inferior and get control back on the first
4445 trap. trap_expected now never takes a value > 1.
4446 (init_wait_for_inferior): Initialize static vars when a new
4449 main.c (gdbinit): Add new hook for .gdbinit file name, let
4450 it be overridden by config files as GDBINIT_FILENAME.
4451 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
4452 Both of these are used for VxWorks gdb.
4454 mcheck.c: rename include file "gmalloc.c" to avoid problems
4455 with system include file "malloc.c".
4457 param-no-tm.h: New include file, same as param.h but does not
4458 include the default "tm.h" file. This is used in files where
4459 the target is known, e.g. remote-eb.c or sparc-xdep.c.
4461 param.h: Now just a shell that includes tm.h and param-no-tm.h.
4463 remote-vx.c: New file, VxWorks remote debugging support. Uses
4464 RPC routines that are shared with the target system, in directory
4467 remote.c: Vectorize remote interface.
4469 source.c: Globalize source_path, and make an alias "l" for "list"
4470 since we now have the "load" command.
4472 sparc-xdep.c: Use new param-no-tm.h.
4474 symmisc.c (free_named_symtab): Add new function from Wind River.
4475 However, ifdef it out for now while we think about what it should
4478 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
4480 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
4481 non-Unix-children handle this with their own code in the target
4484 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
4485 source and target lists. Add vx-share to default list of include
4486 directories. Add new files to src and target lists: mem-break,
4487 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
4488 ${srcdir} versions of munch and createtags are used.
4490 * valops.c (find_function_addr): Split out of call_function.
4491 (call_function_by_hand): Rename call_function; this function
4492 calls functions in the target by laboriously patching the target
4493 word-by-word with the right stack, args, regs, etc.
4496 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
4498 Handle AMD 29000 a bit better.
4500 * remote-eb.c (readchar): Mask received char log to make it readable.
4501 (remote_start): Pass arguments down to executing program.
4502 Make startaddr unsigned.
4503 infrun.c (start_inferior): Accept args, pass them to
4505 infcmd.c (run_command): Pass args down to start_inferior.
4507 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
4508 the target object file format.
4509 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
4511 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
4512 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
4514 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
4516 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
4517 * TODO: We did a few things, we have more to do though.
4519 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
4520 * inflow.c (inferior_died): Clear deferred stores.
4522 * Debug problems with dummy frames and calls to the inferior.
4523 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
4524 * sparc-tdep.c (do_restore_insn): Simplify.
4525 (sparc_frame_find_saved_regs): Simplify and fix what we find.
4526 (sparc_push_dummy_frame): Simplify and fix what we push.
4527 (sparc_pop_frame): Slightly more hair here, deciding whether
4528 we are restoring a saved PC or returning to a return address in %i7.
4529 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
4531 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
4532 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
4533 * obstack.h (chunkfun): ditto.
4534 * defs.h (xmalloc, xrealloc): ditto
4536 * utils.c (quit): Grab the terminal from the child if necessary.
4538 * inflow.c (term_status_command): Rename to term_info, change
4541 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
4542 (is_delayed_branch): Speed up.
4543 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
4544 Still missing some float ops, and needs testing.
4546 * Support for input and output radixes other than base 10
4547 * defs.h (input_radix, output_radix): Declare.
4548 * expread.y (yyparse, parse_number): Handle changes of input
4549 radix, and ambiguous names-or-numbers in radixes >10.
4550 * printcmd.c (print_scalar_formatted): Print formatted hex
4551 numbers in varying column widths.
4552 * valprint.c (val_print): Use output_format to print scalar ints.
4553 (set_input_radix, set_output_radix, set_radix): Create.
4554 (set_output_radix): Set output_format from output_radix.
4555 (_initialize_valprint): add `set radix' but leave the others off.
4557 * main.c (execute_command): Let stupid questions be turned off.
4558 (_initialize_main): Handle "set stupidity", etc.
4560 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
4561 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
4563 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
4565 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
4566 bfd stuff is still screwed up, but with some manual work, it
4569 * breakpoint.c (bpstat_do_actions): Start over if a command
4570 proceeds the inferior, since the inferior will have stopped and
4571 will need to have its new stop-actions taken care of.
4573 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
4574 compiler fits, simplify it.
4576 * gdb.texinfo (directory command): Doc new dir command.
4577 source.c (directory_command): "dir" now puts things on the front
4578 of the path, moves dups up front, and handles multiple names
4579 on the command line, inserting each one in order. It also
4580 blows away cached line and full_filename info.
4582 * stack.c (backtrace_command): Skip "more stack frames follow"
4585 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
4586 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
4587 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
4588 The only odd one was Gould NP1, which had defined vprintf to
4591 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
4592 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
4593 variable, inspect_it.
4594 valprint.c (print_string, val_print): Use the global inspect_it
4595 to indicate whether to print in Epoch style or normal style.
4597 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
4599 * printcmd.c (call_command): add an alias for the "print" command
4600 which runs expressions and doesn't print the result if void.
4601 (print_command_1): implement it.
4603 * command.c: Remove #if 0'd code. Initialize all the fields
4604 in add_cmd (). Rename do_nothing_command to
4605 not_just_help_class_command, and make it externally visible.
4606 command.h: add user_commands to struct.
4607 * main.c (define_command): Don't overload c->function with a char
4608 string as well as a function pointer.
4610 * eval.c (evaluate_subexp): Reinstall tiemann changes to
4611 calling convention of value_struct_elt () that got dropped in
4614 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
4615 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
4617 * tm-sparc.h (POP_FRAME): replace some constants with defines.
4619 * sparc-xdep.c (store_inferior_registers): defer stores to regs
4620 until a good time (e.g. when we are about to run the child),
4621 saving ptrace calls.
4622 * infrun.c (proceed): handle DO_DEFERRED_STORES.
4623 * tm-sparc.h: define DO_DEFERRED_STORES.
4625 * sparc-xdep.c (store_inferior_registers): when storing float
4626 registers, don't store stack regs too. When storing the SP,
4627 however, DO store the stack regs too. This fixes a bug in which
4628 the dummy frame is not recognized when a call_function finishes,
4629 because its frame pointer (in the stack regs) was never
4631 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
4632 even though we don't know how to read them from an inferior.
4633 valops.c (call_function): Comment about storing SP.
4635 * infrun.c (save_inferior_status): Save away the original bpstat
4636 chain so it can be restored later. Install the copied version for
4637 use by whoever saved the status. It will be blow away by
4638 restore_inferior_status, and the original chain restored. This is
4639 important for people who have pointers into the original.
4641 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
4642 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
4643 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
4646 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
4648 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
4649 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
4650 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
4652 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
4654 * Merge Mike Tiemann's multiple inheritance changes from Sun.
4655 Store the baseclasses in a type struct starting from array element
4656 0 rather than from the unusual array element 1.
4658 dbxread.c: the above.
4659 (virtual_context): Add
4660 Read new debug information about which virtual function table
4661 a virtual function is from, and store it in fn_field.fcontext.
4663 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
4664 TYPE_FN_FIELD_STATIC_P.
4666 symtab.c: the above.
4667 valops.c: the above. Handle pointer casts of object *'s.
4668 (search_struct_method): Add.
4669 (value_struct_elt): First arg is now a pointer to a value, and is
4672 valprint.c: the above.
4673 values.c (value_virtual_fn_field): Add type arg. Handle
4674 offsetting to the proper object when calling virtual fns.
4676 (baseclass_addr): Add valuep arg.
4678 * README: Document the current state of BFD config (missing).
4679 * TODO, ChangeLog, Makefile.dist: Roll version.
4680 * WHATS.NEW: Add summary of changes since 3.5.
4682 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
4684 * dbxread.c (read_struct_type): Clear bit vectors whenever
4686 symtab.c (B_CLRALL): define.
4688 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
4689 using == rather than =. Huh... This fixes the dreaded problem
4690 wherein builtin_type_int becomes TYPE_CODE_FLT.
4692 * core.c (info_files): Show the inferior pid.
4694 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
4695 already knows how to look in the source directory.
4697 * Remove psymtab hair from many places. Remove duplicated code
4698 for searching symbol tables. Hide psymtabs from most places.
4699 Make it fast to get from a psymtab to its symtab.
4701 blockframe.c (blockvector_for_pc): Remove psymtab hair.
4702 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4703 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4704 dbxread.c: export psymtab_to_symtab, make it work if called N times.
4705 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
4706 new symtab completely. New psymtabs get symtab pointer
4707 initialized to zero. Remove MI warning printf.
4708 symtab.h: Comments. Add psymtab to symtab pointer.
4709 (PSYMTAB_TO_SYMTAB): New macro.
4710 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
4711 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
4713 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
4715 (print_frame_info): Avoid special-casing symbols that have not yet
4718 * source.c (open_source_file): Quick path if we have already
4719 located the source file by its full name.
4721 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
4722 find_pc_psymtab. When a name is found in the misc function
4723 vector, search the symbol table for its mangled name, not the
4724 name that the user typed.
4726 * bfd.h: Fix missing comment terminators, make #endifs match.
4728 * valarith.c (value_less): Handle unsigned int comparisons.
4729 Add FIXME about pointer compares, which assume host and target
4730 pointers are the same.
4732 * command.c (do_nothing_command): lint
4733 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
4734 fix comments on debug symbol format for visibility. Actually set
4735 visibility of symbols.
4736 main.c (echo_command): lint; use <readline/history.h>.
4737 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
4738 obstack.h (_obstack_blank): Rearrange pointer math to avoid
4739 pointing past end of allocated memory; saber complains.
4740 obstack.h: Declare the external functions that we use.
4741 valarith.h: use <string.h>
4742 solib.c (solib_add): lint.
4744 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
4746 * main.c (initialize_main): Default info_verbose to off, now that
4747 symbol reading is fast.
4748 (quit_command): Avoid clobbering exec_bfd while quitting.
4750 * Initial BFD (binary file diddling library) merger:
4751 coffread.c: Change AOUTHDR to struct exe_hdr.
4753 core.c: initialize initialized data at compile time.
4754 (core_file_command): Move from coredep.c, convert to bfd.
4755 (xfer_core_file): Convert to bfd.
4756 exec.c (exec_file_command): use bfd routines.
4758 mips-tdep.c: Remove exec_file_command and friends.
4761 * coredep.c: (fetch_core_registers) Convert core_file_command to
4762 fetch_core_registers.
4763 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
4765 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
4766 (my_bfd_read): More bogosity, which I don't think we call.
4767 (program_name): Remove this atrocity asap!
4769 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
4772 values.c: allocate_repeat_value was not clearing the
4773 optimized_out field.
4774 (value_static_field): minor stylistic fix (wrong macro was used).
4775 valops.c (value_struct_elt_for_address): didn't work for C++
4778 * signame.c (_initialize_signame): Initialize signal names once.
4780 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
4781 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
4782 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
4784 * remote-eb.c: Support user-settable baud rates on the serial port.
4786 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
4788 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
4790 * tconfig/sun3os4: Remove warning about native assembler,
4791 since it also occurs in the xconfig file.
4793 * findvar.c (registers): Allocate some slop after `registers'
4794 to prevent stray accesses from trashing the next variable.
4796 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
4797 on the sun-3, by changing the #ifdef from `sun3' (which is not
4798 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
4799 vars, which happened to follow `registers' in the executable.
4801 * readline/history.c (history_search): Heed gcc-2's advice
4802 and parenthesize && inside ||).
4804 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
4805 tm-29k.c: Insert FSF copyright headers.
4807 * remote-eb.c: Better comments.
4809 * Makefile.dist: Update to 3.91.6.
4810 * TODO: note PREPARE_TO_STORE problem.
4812 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
4814 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
4816 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
4818 * infrun.c (wait_for_inferior, at end): Don't set up
4819 prev_* if the inferior no longer exists.
4821 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
4822 CANNOT_EXECUTE_STACK.
4823 valops.c (call_function): Use it.
4825 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
4827 * inferior.h (PC_IN_CALL_DUMMY): New macro.
4828 infrun.c (wait_for_inferior, 2 places): Use it.
4830 * values.c (value_being_returned): Only use
4831 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
4833 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
4834 right thing for remote-eb.c.
4836 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
4837 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
4839 * blockframe.c: Put get_frame_saved_regs inside #if !defined
4840 (FRAME_FIND_SAVED_REGS).
4842 * findvar.c ({fetch,store}_registers): Check for
4843 REMOTE_{FETCH_STORE}_REGISTER macro.
4845 * findvar.c (get_saved_register): Add argument lval and
4846 change meaning of argument addr.
4847 findvar.c: Change calls to get_saved_register to reflect
4848 new calling convention.
4849 valops.c (value_assign): Use get_saved_register instead of
4850 find_saved_register.
4852 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
4854 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
4855 an (uninitialized) pointer to one. Use "&" when passing it
4858 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
4860 * coffread.c (getfilename): Use DGUX x_offset and x_name if
4863 * coffread.c (symbol_file_command): Put semicolon after
4865 Put safe_to_init_tdesc_context in #if defined (TDESC).
4866 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
4867 coffread.c: #include <sys/stat.h>.
4868 (read_coff_symtab): Typo: in_source_files -> in_source_file.
4869 Add missing ')' in check for "lc%" and friends. Remove
4871 Declare read_one_sym() at top of file.
4872 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
4873 MC68WRMAGIC can have the same value without causing a duplicate
4876 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
4878 * Allow a Makefile to be built without building the
4879 tm and xm file links that screw up builds in subdirectories.
4880 This is done with `config.gdb none', then you can do things
4881 like `make gdb.tar.Z'.
4882 * tconfig/none: Config file for no target system
4883 * xconfig/none: Config file for no host system
4884 * config.gdb: If no TM or XM files are called out by the
4885 host or target file, don't make links for them.
4887 * cplus-dem.c: Add documentation.
4889 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
4890 simple error, so the user's gdb doesn't crash due to some object
4891 file problem (e.g. somebody is rebuilding the file out from under
4894 * printcmd.c (print_address_symbolic): demangle the symbol.
4896 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
4897 Motorola copyrights in it. Make "make gdb.tar.Z" work.
4898 (alldeps.mak): sort and uniq all results from this; duplicates
4899 hose gdb.tar.Z link building. Remove RCS files from
4900 tconfig and xconfig. Add config files for sun386. Add
4901 a few odd files to OTHERS and HFILES.
4903 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
4905 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
4906 Roll version number to 3.91.5. Make lint work in bindir.
4908 * README: Document cross-debugging and new file structure.
4910 * blockframe.c: Lint. Include "value.h" to declare read_register.
4911 (find_pc_partial_function): remove duplicate line.
4913 * command.h: Lint. Declare error_no_arg and dont_repeat.
4915 * tm-news.h: Remove inadvertently duplicated stuff.
4917 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
4918 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
4920 * config.gdb: Allow `config.gdb host target' form. Clean
4921 up previous change that printed bogus messages when you just said
4924 * core.c: #include "command.h" for lint.
4927 * main.c: Remove some casts of enums. Lint.
4934 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
4936 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
4937 read it from memory. This will allow us to save ptrace calls
4938 eventually. Changed caller single_step too.
4940 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
4941 that we aren't going to use, saving many ptrace calls, especially
4942 when watchpointing or single stepping. Use some #define's for
4944 (store_inferior_registers): Ditto.
4945 (core_file_command): Use some #define's for constants.
4947 * tm-sparc.h: Add #define's for some register numbers, so we
4948 can eliminate the use of random constants in sparc-xdep.c.
4950 * stack.c (frame_command, print_frame_info, up_command,
4951 down_command) Remove frame_changed, since it
4952 causes a bug and doesn't seem to do anything useful. In some
4953 places it was used as a flag, in others as a stack level (?).
4955 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
4956 default is to use the portable (vprintf) version rather than the
4958 * xm-news.h (MISSING_VPRINTF): Add.
4960 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
4962 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
4964 * Remove stuff that forces -Bstatic linking of gdb, and warnings
4965 about linking debugged programs -Bstatic in the sun?os4 config
4966 files in tconfig and xconfig subdirectories.
4968 * main.c (main): Remove unreached exit(0) now that we exit
4971 * Create TODO file for online bug list. There are too many
4972 "little" bugs to keep track of on paper.
4974 * Change Projects file to refer to bug-gdb@cygnus.com
4975 rather than kingdon@ai.
4977 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
4979 * Makefile.dist (VERSION): 3.91.4 now.
4981 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
4982 (condense_misc_bunches): Add sanity check that misc_count is
4983 the same as the number of symbols in the bunch.
4985 * coffread.c: rename init_misc_bunches. Pass an argument
4986 to condense_misc_bunches (a zero).
4988 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
4989 every time we are called; don't rely on our caller to do it.
4990 (add_file): Remove call to init_misc_bunches.
4992 * mipsread.c: Only warn, don't error, if unknown symbol types.
4993 This keeps an old gdb from falling on its face if it sees newly
4994 extended symbol info. Rename init_misc_bunches.
4996 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
4998 * Merge in changes from Per Bothner for DECstations and other
4999 MIPS stuff. The rest is Bothner speaking:
5001 The next message is a merger of Alessando Forin's mips port with
5002 mine. I've tried to use my good if biased judgment to get
5003 the best of both. It *does* need testing.
5005 Some of the changes are general, *not* mips-specific.
5008 Didn't believe in little-endian bit order.
5009 There are still inconsistencies about whether flags
5010 like BITS_BIG_ENDIAN are integer (#if ...) or
5011 boolean (#ifdef ...). I tried to paper over them.
5013 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
5014 Moved some misc_function code that was common to
5015 {dbx,coff,mips}read.c to symtab.c.
5016 In the process, I think I cleaned things up a bit.
5017 At the same time, moved obsavestring and obconcat to symtab.c.
5020 Removed obsolete condense_addl_misc_bunches (use
5021 condense_misc_bunches(1) instead).
5024 Needed to include <sys/dir>, at least on DECstations.
5026 valops.c, mips-tdep.c, tm-mips.h:
5027 Added PUSH_ARGUMENTS macro to support funny argument-pushing
5028 conventions (when STACK_ALIGN is insufficient).
5029 Needed on mips, where doubles need 8-byte alignment,
5030 but ints only need 4.
5033 Removed cruft that was not being used.
5034 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
5037 Print $ before register-names (I think that makes things a little
5039 Never print two instructions, even if one delays.
5040 Removed hex-disassemble set_cmd. (This is not mips-specific,
5041 so I think the argument is whether it is generally worthwhile or not.
5042 I'm inclined to think not, given how easy it is to
5043 convert between radixes in gdb.)
5046 This is basically Alessando's code.
5047 It doesn't use obstacks; I changed it to use obstacks
5048 in a few minor places where using malloc causes a
5049 memory leak. (Probably, more places could/should be changed.)
5050 I added record_misc_function where it was missing.
5051 In symbol_file_command and add_file_command, I tried
5052 to make the code consistent with more recent versions.
5053 Minor sylistic changes in parse_procedure.
5054 Make a .gdbinfo. psuedo-symbol point back to the real
5055 procedure symbol (using the isym field).
5058 This is basically from my port, but with a lot of details
5059 and a number of routines merged in from Alessando's version.
5060 I basically used my code "raw" backtrace (use heuristics
5061 from the actual code, rather than symbol table info) - though
5062 the idea is Alessandro's. I feel my code is a little cleaner
5063 here, particularly in being a little more flexible, such as being
5064 able to handle gcc-produced code (which it now can).
5065 It also doesn't do frame caching (which is not useful
5066 more recent gdb versions).
5067 I also used my code for push_/pop_dummy, more or less.
5068 I tried to incorporate AF's code for testing sigtramp
5069 while backtracing; I probably got it wrong.
5070 Added mips_print_register, which tries to scrunch as much
5071 information as possible on a screen...
5072 Removed the skip-prologue set_cmd. As with hex-disassemble (see
5073 under mips-pinsn.c), I don't see anything mips-specific here,
5074 and I don't see it being all that useful anyway.
5077 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
5078 Use more register names (rather than hard-cases numbers).
5080 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
5082 * Hack up 3.90.11 changes:
5084 * Makefile.dist (depend): parameterize $(GCC).
5085 Add solib.c and solib.o.
5086 (readline): Fix vpath for both absolute or relative SRCDIR.
5088 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
5089 Also, let the part I didn't understand at least compile so
5090 I can test the rest. FIXME.
5092 * dbxread.c: Fix thinko using strcmp.
5093 (init_psymbol_list): declare static.
5094 (partial_symbol_file_open): Comment cleanups better, avoid
5095 cleaning up the string table since the caller will do that.
5096 Move the stat for mod time into symbol_file_command, temporarily.
5097 (There should be a mod time for each symbol file, eventually,
5098 to control its rereading. FIXME.)
5100 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
5101 SunOS, which gives error for shared libs otherwise. (From
5102 Schaefer, probably FIXME needs work for portability.)
5104 * solib.c: Move #include "param.h" to work.
5105 Lowercase all the Uppercase Letters In the Messages.
5106 (find_solib): Clean up inferior_so_name for debug printouts.
5107 Allow no argument, to mean all shared libraries.
5109 * symmisc.c: include param.h to get CLEAR_SOLIB.
5111 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
5113 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
5114 to 3.90.11. ChangeLog entries below are from this.
5116 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5120 * Makefile.dist (HFILES): Add tm-sunos.h.
5122 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5126 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
5128 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
5130 * sparc-opcode.h Added single-operand version of rett.
5132 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5134 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
5135 Put parens around gcc_p in expansion.
5137 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5139 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
5141 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5143 * Changes for Sun shared libraries:
5144 blockframe.c (find_pc_partial_function): If a non-text symbol
5145 is found, set *address = pc - FUNCTION_START_OFFSET.
5146 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
5147 Disable breakpoints instead of giving an error.
5148 source.c (select_source_symtab): Initialize cs_pst.
5149 symmisc.c: Call CLEAR_SOLIB if defined.
5150 symtab.h: Make text{low,high} CORE_ADDR not int.
5151 (psymtab): New field addr.
5153 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
5154 (record_misc_function): Give correct type for N_DATA symbols.
5155 (condense_misc_bunches): do "misc_function_count = j" regardless
5157 Take code which is shared between symbol_file_command and
5158 add_file_command and put it into partial_symbol_file_{open,read}.
5159 Split add_file_command into add_file_command and add_file.
5160 Make psymtab_to_symtab read in the string table if the file
5162 Two new parameters to read_dbx_symtab and start_psymtab.
5163 tm-sunos.h: New file.
5165 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5167 * infcmd.c: Change cont_command to continue_command and "cont"
5170 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5172 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
5174 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
5176 * values.c (USE_STRUCT_CONVENTION): Check for structures of
5177 size 1,2,4,8 rather than size < 8.
5179 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
5180 as necessary, not just once.
5182 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
5184 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5186 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
5188 * tm-news.h: Add CALL_DUMMY_*.
5190 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
5192 * config.gdb: In list_host, list_target, use ${i}, not $i.
5194 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5196 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
5198 * sparc-opcode.h: Change all store floating-point state register
5199 instructions to have the right match & lose fields.
5201 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5203 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
5205 config.gdb: If srcdir != ., create readline directory and
5206 copy a makefile into it.
5208 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
5209 consistency with POSIX.
5211 * breakpoint.c (bpstat_stop_status): Disable watchpoint
5212 when we exit its exp_valid_block.
5214 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
5216 * Makefile.dist: Bump version to 3.91.3.
5218 * Clean up handling of breakpoint commands (somewhat).
5219 Prompted by Tiemann bug report "cont 10" doesn't work any more.
5221 inferior.h: Add breakpoint_proceeded to inferior status struct
5222 and globals; save it and restore it.
5223 (clear_breakpoint_commands): Cleanup, remove old #define.
5225 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
5226 (save_inferior_status, restore_inferior_status): handle it also.
5227 (proceed): Remove earlier code that set breakpoint_proceeded.
5228 It is now set only in clear_proceed_status.
5229 (clear_proceed_status): Cleanup, use bpstat_clear rather
5230 than clear_breakpoint_commands. No callers need the stop_bpstat
5231 between clear_proceed_status and proceed.
5233 infcmd.c: Add breakpoint_proceeded definition and comment.
5234 (cont_command, jump_command, signal_command): Move call to
5235 clear_proceed_status right next to call to proceed.
5237 breakpoint.c (bpstat_do_actions): Avoid clobbering our
5238 caller's argument while running down the chain of breakpoints.
5239 Use new variable "breakpoint_proceeded" to determine when
5240 a command that it executes moves the inferior past the
5242 (bpstat_clear): Handle NULL argument.
5243 (bpstat_clear_actions): Avoid useless call to
5244 breakpoint_auto_delete.
5245 (delete_breakpoint): Clean up bpstat's that are pointing to
5246 the deleted breakpoint from the stop_bpstat chain.
5247 (breakpoint_auto_delete): Simplify.
5249 * Clean up handling of EOF, error on stdin, etc. This was
5250 prompted by a network problem that caused gdb to go into an
5251 infinite loop filling up its malloc'd memory.
5253 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
5254 not clear_breakpoints_commands, which is now gone.
5255 (main): If command_loop returns (e.g. from EOF on stdin), do
5256 a quit_command (looping back to command_loop if quit_command
5257 doesn't really quit).
5258 (command_loop): check result from command_line_input and
5259 exit if it returns NULL, rather than passing the NULL to
5261 (gdb_readline): Free malloc'd result space before returning
5264 * utils.c (query): Handle C-d to mean "yes", just as if the
5265 input was not a terminal. Also avoid infinite loop if EOF
5266 occurs in mid-input-line before newline. This allows
5267 query to be used at EOF on stdin with reasonable results.
5269 * infrun.c (proceed): Set breakpoint_proceeded.
5271 * values.c (value_as_long): Avoid infinite recursion for enums.
5272 (_initialize_values): Fix typo in help msg (kingdon).
5274 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
5275 RL_LIB for linking. This allows -lreadline for linking
5276 and nothing for dependencies, once readline is a real library.
5278 * config.gdb: Jim Kingdon: give useful error message if the
5279 host or target type is not recognized.
5281 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
5282 it just defines it. Dumb, but deal with it.
5284 * Jim Kingdon suggests:
5285 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
5287 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
5289 * Makefile.dist (VERSION): Bump version # to 3.91.2.
5291 * Clean up Bothner's changes.
5293 * blockframe.c (clear_pc_function_cache): New function.
5294 * blockframe.c: remake cache_pc_function_* static.
5295 * dbxread.c (symbol_file_command): remove references to
5296 cache_pc_function_* variables.
5297 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
5298 * printcmd.c: Avoid kludging a global variable (addressprint)
5299 to avoid printing the address of a string twice. Instead,
5300 pass the format letter 's' down low enough that it can be seen
5301 to avoid this problem.
5302 (print_formatted): Pass format arg to value_print.
5303 (restore_addressprint): Remove function.
5304 (do_examine): Avoid hacking addressprint, cleanups and such.
5305 (print_frame_args): Add a comment to a Bothner change.
5306 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
5307 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
5308 to wipe out the values cached in blockframe.c.
5309 * symtab.c (find_method): Add comment saying how big you must
5310 allocate to be "big enough". Per being terse again.
5311 * valprint.c (val_print): Handle format letter "s" to print
5312 strings without addresses. Add comment to vtbl printing code
5313 which casts with wild abandon. Rearrange reference-printing
5315 @0xaddr: value (print w/addressprint)
5316 value (print w/~addressprint)
5317 @0xaddr (parameter lists w/addressprint)
5318 or nothing (parameter lists w/o addressprint)
5320 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
5322 * Merge more changes from Per Bothner:
5324 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
5325 annoying) that I tried to improve it. Here are my suggestions.
5327 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
5330 Do automatic de-reference when taking the address of a reference.
5332 Don't deref_ref when printing parameter lists.
5334 More attempts at treating refernences properly.
5336 In val_print, if deref_ref==0, don't print dangling " = ".
5338 Add COERCE_REF macro, which de-references an REF.
5340 * Merge changes from Per Bothner:
5342 * Fixed (Sony news)-specific configuration problems.
5343 * Fixed other problems with using vanilla pcc and libc (enum problems;
5344 assumption that vsprintf exists).
5345 * Some major speed-ups (finc_pc_partial_function now caches a match;
5346 parsing avoids duplicate symbol_lookup calls).
5347 * Changed handling of baseclasses (no longer use baseclasses field
5348 of struct type, use the first n_baseclasses fields instead).
5349 * Various minor changes/fixes, most C++-related.
5352 Cache the most previous match from find_pc_partial_function.
5353 (Save both low and high ends of matching function's pc range.)
5354 This speeds up the loop of infrun.c:wait_for_inferior quite
5355 a bit, and makes step/next commands much zippier.
5357 Added an enum->int cast (otherwise, some compilers barf).
5359 No longer set baseclass offset to 0, since multiple
5360 inheritance now mostly works.
5361 Added a number of casts, to shut up compiler warnings
5362 (after stabs where made enums, not ints).
5363 When discarding a symbol table (in symbol_file_command),
5364 must clear the cache introduced in blockframe.c.
5365 Don't convert $vtbl_ptr_type to vtbl any more.
5366 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
5367 Mask off sign bit emitted by g++ for virtual table offset.
5368 Set voffset to -1 (not 1) for static member functions.
5370 Changed parsing/lexing of names to avoid doing symbol lookup twice
5371 (once when lexing to determine symbol class, once for real).
5372 Now only call symbol_lookup once. Fields of 'this' win especially big.
5374 Subpress printing addr twice in the case of 'x/s addr'.
5376 lookup_basetype_type is no longer used.
5377 Add find_methods as recursive helper function to decode_line_1.
5378 This allows multiple inheritance to work.
5379 Also, once one or more matches has been found, do not look in
5380 base-classes. (Baseclass methods would be overridden, anyway.)
5382 Removed baseclasses array in struct type.
5383 Instead of using baseclasses[i], use fields[i-1].
5384 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
5385 Changed sign convention of voffset (previous was inconsistent).
5387 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
5389 Used to assume existence of vsprintf. Re-written to not need it
5390 if HAVE_VPRINTF is undefined.
5392 typecmp was too pessimistic. Made it less so.
5394 Don't print space after address.
5395 If vtable points to a misc symbol (with 0 offset), print it,
5396 since that indicates the actual class of the object.
5397 Changed ype_print_derivation_info to use new inheritance
5398 scheme (without baseclasses vector).
5400 In value_primitive_field, fixed some bugs left over from previous set of fixes.
5401 Also, changes needed because TYPE_BASECLASSES were removed.
5403 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
5405 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
5408 If there is no path set, and the symbols don't indicate what directory
5409 a file was compiled in, look in the current directory. But either
5410 a path or a known compilation directory will prevent this.
5413 Three independent bug fixes:
5414 * Remove the #if 0 block that breaks some stuff.
5415 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
5416 adapt gdb to either SunOS 4.0.* or 4.1.
5417 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
5420 Instantiate the class T when looking for methods in it. (Tiemann@sun)
5423 (type_print) Demangle the name being printed.
5424 (type_print_base) Handle botched demangling without coredump (tiemann).
5427 (check_stub_method): Document routine.
5428 (tiemann) fix bug for no-arg functions
5429 Avoid clobbering beyond end of malloc'd storage.
5430 Terminate the argument list properly.
5432 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
5434 * Changes merged by John Gilmore:
5437 In breakpoint_1, use new print_address_symbolic instead
5438 of find_pc_partial_function. (This forces use of assembler-level
5439 addresses, and avoids misleading non-mangled source-level names.)
5441 Generalize ansi argument such that -1 means skip arglist totally.
5442 Removed global variable print_ansi_qualifiers (which made
5443 code non-reentrant), in favor of extra explicit arguments
5444 to internal routines.
5446 Add new helper function print_address_symbolic.
5447 Use find_pc_misc_function instead of find_pc_partial_function
5448 (since we want assembler-level symbols here).
5450 Print unknown function as just "f (...)", not "f (...) (...)".
5451 Use new fputs_demangled explicitly.
5453 Fixed a typing violation (problem: value.h cannot be imported
5454 without renaming many variable in this file).
5455 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
5456 decode_line_1: Moved forward some never-reached code.
5457 Made decode_line_2 skip function prologues correctly.
5459 fputs_filtered should not demangle by default.
5460 Add new fputs_demangled to demangle on demand..
5462 Change value_struct_elt to use value_primitive_field (using recursive
5463 utility function search_struct_field). This allows foo.bar to work
5464 for multiple inheritance (so far only for data fields).
5465 Change check_field in the same way (recursive helper function
5466 to support multiple inheritance).
5467 (Note: there are more of these problems that I haven't fixed.
5468 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
5469 value_of_this: 'this' symbol name is now just "this", note "$this".
5471 Don't print static members.
