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

120 * Makefile.in (VERSION): Set to 4.1.
121 * language.c (set_language_command): Print useful help message,
122 and restore the language string after giving help.
123 * valprint.c (typedef_print): Print typedef in C or M2.
124 * symtab.c (list_symbols): Use it.
125 * main.c (main): Avoid any output before (gdb) prompt when -q.
126 * language.c (set_language_command): Handle errors by restoring
127 the language string to its current state (fix from A. Beers).
128 * doc/gdbint.texinfo: Roll in information from README. Rearrange
129 "how to install" and "how to print the doc" stuff so it drops
131 * configure.in: Rename rtpc CPU to romp to match config.sub.
132 * README, WHATS.NEW, TODO: Update for gdb-4.1.
134 Fri Sep 20 17:39:14 1991 Roland H. Pesch (pesch at cygnus.com)
136 * doc/gdb.texinfo: Updates from ChangeLog. set/show write,
137 autoloading shared libs, copyright etc on GDB startup, clean up $_
138 and $__ index refs, set/show listsize and related updates to list
139 cmd. New host/target configs.
141 Fri Sep 20 15:46:00 1991 Roland H. Pesch (pesch at cygnus.com)
143 * doc/Makefile: generate aux version-no file doc/gdbVN.m4
144 from main Makefile.in version definition
145 doc/gdb.texinfo: use version recorded in doc/gdbVN.m4 for current
147 Makefile.in (setup-to-dist): generate doc/gdbVN.m4
149 * doc/gdb.texinfo: merge new language-switching and lang-specific
152 Fri Sep 20 15:00:57 1991 Per Bothner (bothner at cygnus.com)
154 * mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
155 compilers (which may lack stddef.h).
157 Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com)
159 * dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and
160 N_WARNING are the same except for the N_EXT bit, so just use their
161 values alone, rather than OR-ing them with N_EXT.
163 Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com)
165 * mipsread.c (parse_lines): Deal with negative extended line
168 * c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid
169 global symbol conflicts.
171 Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
173 * .gdbinit: Move 'set complaints' to top, so it runs even in
174 case we aren't debugging GDB.
175 * language.c (_initialize_language): Fix type check and range
176 check documentation strings.
177 * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
178 language.c can use it. (Though language.c should really not be
179 handling warnings/errors the way it does, FIXME.)
180 * symtab.c (lookup_primitive_type): const lint.
182 Bugfix from Peter Schauer:
183 * source.c (lines_to_list): Make signed, to avoid comparison
184 going unsigned and complaining that -3 is too high for 21 lines.
185 * stack.c (lines_to_list): Ditto.
187 Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
189 * Makefile.in (HFILES): Add minimon.h.
190 (VERSION): Roll version number to 4.0.95.
191 (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
192 New rules for building distributions. Normal distribution
193 is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
194 one level up from here; it calls make-proto-gdb.dir to build a
195 directory `proto-gdb' which is an image of the release. The old
196 `gdb.tar.Z' rule still works too.
197 * config.sub, configure: Roll in latest from ..
199 Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
201 * doc/gdbint.texinfo: Reorder contents; reorganize new-host,
202 new-target, and new-config chapters; fix minor typos; come closer
203 to usual GNU markup conventions for @file @samp @code @var.
205 Thu Sep 19 17:04:12 1991 Per Bothner (bothner at cygnus.com)
207 Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
208 * mipsread.c (parse_partial_symbols): Enter the name of all
209 structs/unions... into the psymtab so we can access them if the
210 symtab is not read in.
211 * mips-tdep.c: Remove some unneeded #includes.
212 * xconfig/dec3100: Add HAVE_STRSTR.
214 Thu Sep 19 15:14:23 1991 John Gilmore (gnu at cygnus.com)
216 * Makefile.in: Circumvent Sun Make bug on *-exp.tab.o.
217 * c-exp.y, m2-exp.y: Lint.
218 * m2-exp.y: Avoid using yytname[] which is a Bison-ism.
219 * valprint.c (val_print_fields): Check for stub type.
220 * mipsread.c (_initialize_mipsread): Avoid using
221 builtin_type_void at initialize time.
222 (mipscoff_symfile_read): use it now.
224 Wed Sep 18 15:55:51 1991 John Gilmore (gnu at cygnus.com)
226 Merge multiple-language support, and partial Modula-2 support,
227 from Andrew Beers <beers@cs.buffalo.edu>.
229 * i387-tdep.c: New file, consolidates most 80387 support,
230 and eliminates host dependency on double<->extended conversions.
231 * i386-xdep.c, symm-xdep.c: Remove most 387 support.

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

323 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
325 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
326 entries are enclosed herein. Not all of these changes
327 have been merged into the master GDB sources -- check the
328 ChangeLog above here for the merge log.
330 Mon Jun 3 17:05:45 EDT 1991
332 m2-exp.y Created. Tested outside of GDB for a few days. Proper
333 operators were added, C specific operators and tokens
334 removed. yylex() revamped to some extent. Still things
335 missing from the grammar, such as sets.
336 Tested for two weeks in GDB v3.5.
338 Tue Jun 11 17:23:48 EDT 1991
340 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
341 so they are built-in. Sort of a hack.
343 Fri Jun 14 12:53:51 EDT 1991
345 m2-exp.y Added range checking for numeric constants. Any numeric
346 constant is assumed to be of builtin type INTEGER unless:
347 (1) it is octal or hexadecimal, in which case it is a
348 CARDINAL; (2) it is too big to fit into an INTEGER, in
349 which case it is a CARDINAL.
350 eval.c Added simple range checking for +, -, and * on integers.
351 Doesn't work very well for *, since 6 * 1,000,000,000 =
352 1,705,032,704, which fails the simple test of result >=
353 first_operand, no matter in what order the operands are.
355 Tue Jun 18 14:11:30 EDT 1991
357 Broke the parser into parts, one containing the C grammar and the other
358 containing code to be shared by all of the grammars.
360 The following files no longer exist:
365 The following files were added:
367 c-exp.y (The C grammar)
368 m2-exp.y (The Modula-2 grammar)
369 parser-code.c (Code that is shared by the above grammar)
373 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
374 now necessary to use the Bison compiler compiler, since it
375 will generate function/variable prefixes other than yy.
377 Tue Jun 18 16:47:49 EDT 1991
379 symtab.[ch] Added the external variable working_lang, than holds the
380 value of the current working language.
381 Added the ennumerated type language_mode, with the values
382 language_auto and language_manual, the former meaning that
383 GDB sets working_lang as needed, and the latter meaning
384 that the value of working_lang is totally under user
386 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
387 REAL, BOOLEAN and CHAR. Also added the type codes
388 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
389 utils.c Added set_language_command and show_language_command to
390 implement the GDB support commands "set language" and
392 expression.h A number of identifiers were added to the type exp_opcode
393 to facilitate Modula-2 builtin functions, integer
394 division, and array indexing.
396 Wed Jun 19 13:25:58 EDT 1991
398 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
399 if the language specified by working_lang requires the use
400 of strict typing of expressions. Eventually, even this
401 will be able to be changed by the user.
402 Added the macro RANGE_CHECK, which evaluates to non-zero
403 if the language specified by working_lang requires the
404 checking of a value against the domain of its type.
405 Eventually, even this will be able to be changed by the
407 language.[ch] Predicates involving types (simple_type, ordered_type,
408 same_type, integral_type, numeric_type, character_type,
409 boolean_type, float_type) are added. These predicates are
410 based on the current value of working_lang, and are handy
413 Wed Jun 19 15:39:34 EDT 1991
415 eval.c Added the function type_array_rank which computes the rank
417 valarith.c Added the funtion value_bool, which when given a integer
418 value.h value (ie. struct value *) as an argument, it returns a
419 boolean value (ie. struct value *) true if that integer
420 is non-zero, and a boolean value false otherwise.
421 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
422 will print out properly.
424 Wed Jun 19 16:36:34 EDT 1991
426 valops.c Added the function value_capitalize, which returns it
427 value.h argument capitalized if its argument is a lowercase
428 letter, or the argument unchanged if its argument is not a
430 valarith.c Added the function range_check_p, which returns non-zero
431 value.h if its value argument is between the integral bounds upper
433 Added the function range_check_enum_p, which makes sure
434 that its value argument is a valid member of the domain of
436 Added the function range_check_range_p, which makes sure
437 its value argument lies between the upper and lower bounds
438 of its type argument, which must be a ranged type.
439 Added the function check_array_index, which range and type
440 checks an index of an array.
441 Added the function value_multi_subscript, which computes
442 array[idx1,idx2...idxN], given a value array and an array
443 of values representing indicies.
444 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
445 unpack_long to work with TYPE_CODE_BOOL and
448 Wed Jun 19 18:04:08 EDT 1991
450 symtab.c Stored pervasive types in a structure and make
451 lookup_pervasive_type() a lookup function that was based
452 on working_lang. If lookup_pervasive_type() returned
453 non-zero, then that value was returned (a fix, since
454 before it simply wouldn't return the pervasive type.)
455 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
456 non-zero if the language specified by working_lang means
457 "conversion" when it says "cast".
458 valops.c Added the function value_real_cast(), which performs a
459 value.h *cast*, not a *conversion*, which is what value_cast()
460 does when it can. In particular,
461 value_cast(<float_type>,4) = 4.0, while
462 value_real_cast(<float_type>,4) = some mess.
463 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
464 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
465 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
466 and MIN on integral types. *NOTE*: These are currently
467 hardcoded to work only if there are 8 bits per storage
469 eval.c Made logical functions call value_bool to return a
470 properly typed boolean value, based on working_lang.
472 Thu Jun 20 11:55:27 EDT 1991
474 valprint.c Types now print out in a Modula-2 fashion. This works for
475 the cases when the type is printed out step-by-step, that
476 is, it doesn't work when the name of a structured type
477 (which includes the keyword "struct", etc.) is simply
479 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
480 since type specifications in C and Modula-2 are very
481 different. The C printing of a type is very recursive,
482 whereas in Modula-2 it is generally very simple. C has
483 type prefixes and suffixes, which have no real analogue in
484 Modula-2. Maybe type_print() should call a language
485 specific type printer. This is also advantageous if we
486 compile GDB to exclude some of the languages. We'll just
487 leave those functions out.
489 Thu Jun 20 16:57:10 EDT 1991
491 dbxread.c When reading the complete symbol table in (via
492 psymtab_to_symtab()), the number and types of function
493 arguments are added to a function type. define_symbol()
494 calls add_param_to_type() to accomplish this.
495 Assumption: when we come across a function definition
496 (N_FUN symbol with an 'f' or 'F' in the name), its
497 arguments will appear before another function definition.
498 When a function is found, a pointer to its type is placed
499 in the global in_function_type. Changes that
500 add_param_to_type() makes are to this global.
501 valprint.c The type of a function now includes (for Modula-2) the
502 types of its parameters.
503 eval.c Type checking and a check for the proper number of
504 arguments is now done for function calls. Not sure of the
505 impact this has on C++ member function yet.
507 Thu Jun 20 19:58:48 EDT 1991
509 valprint.c Rewrote the type printer. Broke it into two language
510 specific parts, adding the functions type_print_m2() and
512 An unfortunate consequence is this: if you debugging a C
513 program in Modula-2 mode (why?), info types does not work
514 well with regular expressions, since the types are printed
515 out in Modula-2 terminology, but stored in C terminology.
516 language.[ch] Added the functions new_type_last(), type_keyword(), and
517 type_sep() to aid in the printing of typedefs.
518 symtab.c Made the printing of typedefs as language independent as
519 possible through calls to new_type_last(), type_keyword(),
522 Fri Jun 21 11:50:26 EDT 1991
524 dbxread.c Check all incoming ennumerated types. If it looks like
525 Modula-2's BOOLEAN type, then change the type_code of the
526 type to TYPE_CODE_BOOL so we can process it as a boolean
528 valprint.c Replaced some of the 0x%x with calls to sprintf and
529 hexformat() in val_print().
530 language.[ch] Added the function hex_to_string(), which converts its
531 integral argument to a hexadecimal number (format is
532 language based) and returns the result as a string.
534 Mon Jun 24 12:25:07 EDT 1991
536 valprint.c Some functions call type_print_1() directly, instead of
537 value.h using type_print(), so they can specify where (column) to
538 print things. Since type_print() takes care of language
539 dependence, that needs to be called first. Added a
540 parameter depth to type_print() (so it is now like
541 type_print_1). Changed type_print to type_print_at, and
542 made type_print a macro that passes a depth argument of
544 symmisc.c Changed all calls to type_print_1 to calls to
546 Makefile.dist Made it possible to build GDB for a specific set of
547 depend languages. Do this by passing a definition for the macro
548 LANGS to make. LANGS should be a string containing a
549 space-separated list of language names (ie. LANGS="c m2").
550 The default is to build all languages. Note that grammar
551 files must follow the naming convention of <lang>-exp.y.
552 gdb.lang This holds the current value of the LANGS macro. It is
553 examined every time make is called, and is updated if
555 eval.c Added #ifdef _LANG_<lang> to these files.
556 expread.c Still need to add them to dbxread.c and coffread.c.
564 Mon Jun 24 16:33:11 EDT 1991
566 language.[ch] Added the functions hexformat_pre() and
567 hex_to_string_pre(), which take a prefix argument to
568 include in the format string. Thus, hexformat_pre("08") will
569 return "0x08x" (if the working language is language_c).
570 Made hexformat() and hex_to_string() calls to the above
571 with "" as the prefix argument.
573 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
574 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
575 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
576 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
577 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
578 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
579 valprint.c, vax-pinsn.c
581 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
582 calls to hexformat() and hex_to_string(). Format strings without
583 the leading "0x" were ignored.
585 depend Updated to take the above into account.
588 Tue Jun 25 15:27:18 EDT 1991
590 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
591 and type_check_t to keep track of the current state of
592 range and type checking.
593 main.c Added the variables range_mode, range_check, type_mode,
594 and type_check to record the current state of range and
595 type checking. Added initialization code to main().
596 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
600 Tue Jun 25 17:57:08 EDT 1991
602 dbxread.c process_one_symbol() updates the variable (enum language)
603 source_lang based on the extension of the filename
604 contained in the N_SO sybmol that started this symtab.
605 When end_symtab() is called, the value of source_lang is
606 put into the language field.
607 stack.c select_frame() sets working_lang (and possibly type_check
608 and range_check) to the language field of the symtab
609 associated with the frame that is selected if working_mode
610 is language_auto. If working_mode is language_manual, a
611 warning is printed and working_lang is not set.
612 language.c Added the function set_type_range(), which sets the value of
613 type_check and range_check (if their modes call for
614 automatic setting) based on the current value of
615 working_lang. A non-zero argument will cause the current
616 settings to be output.
619 Wed Jun 26 14:51:40 EDT 1991
621 eval.c Added range checks on assignment.
622 m2-exp.y Added the grammar for sets to the language. Currently,
623 these do not do anything except print an error message.
625 Wed Jun 26 17:01:04 EDT 1991
627 m2-exp.y Added the ability for parse_number() to parse negative
628 numbers. A global flag is set upon encountering a unary
629 minus. This was done to make, for example, 1 parse as a
630 CARDINAL, and not as an integer, per Wirth's examples in
631 Programming in Modula-2 ed.4.
632 valprint.c Added support for "set radix 2" by then setting
633 output_format to 't'.
634 eval.c Implemented range checking on subrange types. Added calls
635 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
636 Implemented MIN and MAX for ennumerated types. The
637 minimum value of an ennumerated type is defined by Wirth
638 as the first identifier, and the maximum as the last.
639 m2-exp.y Made octal numbers ending with "B" be characters and those
640 ending with "C" be numbers, per Wirth's book. (p. 34)
642 Thu Jun 27 14:11:52 EDT 1991
644 stack.c select_frame() now only sets working_lang, it does not
645 notify the user. If working_mode is language_manual, then
646 a warning is issued once.
647 main.c At the end of each call to execute_command(), working_lang
648 is checked against the local static (enum language)
649 current. If they differ and working_mode is
650 language_auto, the new settings of language, type and
651 range checking are printed out.
652 stack.c Modified frame_info() to include the language of the
653 current frame in the output of "info frame".
654 language.[ch] Added the function language_str() which returns the name
655 of the current language.
657 Fri Jun 28 15:33:14 EDT 1991
659 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
660 the language. INCL and DECL currently cause an error,
661 since sets are not implemented yet. INC and DEC are
662 implemented as PREINCREMENT/PREDECREMENT with one
663 argument, and as ASSIGN_MODIFY with two arguments.
664 eval.c Added type checking to the above cases.
665 value.h Added not_lval_constant to the lval_type ennumerated type.
666 not_lval_constant means that the value is a constant
667 value; that is 3 or 'a' or TRUE, not as in a constant
668 identifier. This is used to help coerce numbers such as 3
669 to either signed or unsigned numbers.
670 valops.c Added the function value_coerce_constants() which coerces
671 constant integers as following: if one is a constant and
672 the other is not, the constant's type is set to the type
673 of the other argument. If both are constants and one is
674 signed, the other is converted to a signed constant.
676 Sat Jun 29 17:26:29 EDT 1991
678 valarith.c Added a better range checker. It now checks range
679 (successfully) on integral operations [+-] (signed and
680 unsigned) for any C sized type. Still does not work well
682 int_in_size() returns an integer that is coerced to fit into
683 specified number of bytes.
685 Mon Jul 1 13:04:14 EDT 1991
687 language.[ch] Added the function binop_result_type(), which returns the
688 builtin (struct type *) type that would be the result of a
689 binop on the two values V1 and V2.
691 Wed Jul 3 19:22:53 EDT 1991
693 source.c Extended source_info() to include the source language in
694 the output from "info source".
696 Fri Jul 5 13:48:52 EDT 1991
698 utils.c Moved the support functions for the GDB set/show commands
699 dealing with language into language.c.
700 language.c Added the function language_info(), which displays info
701 about the current working language, type and range check
702 settings. Called via the GDB command "info language".
703 Added an initialization routine _initialize_language(),
704 that sets defaults for the language, type and range
705 variables and sets up the new GDB commands.
706 main.c Language setup moved to language.c.
709 Mon Jul 8 10:10:22 EDT 1991
711 valarith.c Debugged the range checker for arithmetic. Still does not
712 work for multiplication very well.
714 Mon Jul 8 12:40:37 EDT 1991
716 language.[ch] Added the function value_true() which returns non-zero if
717 its argument represents a boolean true value.
718 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
719 check the truth of an expression.
721 Thu Jul 11 12:51:34 EDT 1991
723 language.[ch] Added the predicate structured_type(), which returns
724 non-zero if the argument is a structured type.
725 Added the predicate pointer_type(), which returns non-zero
726 if the argument is a pointer type.
727 eval.c Added the ability to do addition and substraction on
728 pointers and integers. This case simply bypasses the
731 Thu Jul 11 14:41:42 EDT 1991
734 Added the symbol N_DEFD (0x4a) which is a definition
735 module dependency that is used by the GNU Modula-2
736 compiler and the linker. It is not important to GDB,
737 except that [dbx|coff|mips]read.c should ignore these
740 Fri Jul 12 16:07:00 EDT 1991
742 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
743 0 in val_print(). Also added statements to the else part
744 to coerce type (argument to val_print) to a pointer type
745 if it is an "array of unspecified length".
746 valops.c Added the function value_m2_string(), which returns a
747 (value) value which is a constant string, whose type is
748 (ARRAY [0..n] OF CHAR). The length field of the type
749 structure is set to zero, so it will be interpreted as an
750 "array of unspecified length".
751 stack.c Moved the language/frame mismatch check to
752 main.c:execute_command().
753 main.c The working language is recorded each time
754 execute_command() is executed. If working lang has
755 changed during its execution, then the new
756 language/type/range info is printed out for the user. If
757 the working language does not match the language of the
758 frame, a warning is issued.
760 Sat Jul 13 16:16:39 EDT 1991
762 eval.c Moved all the type-checking stuff for operators to
763 language.[ch] language.c. This is so we can keep language-specific
764 stuff (like for what type operators are defined) in
766 language.[ch] Added the function binop_type_check(), which checks to see
767 if its two (value) arguments are type-compatible with its
768 opcode argument. The opcode should represent an operation
769 involving an operator. Also added the macro function
770 unop_type_check, which calls binop_type_check with a
771 NULL second argument.
772 expprint.c Added Modula-2 operators to the op_print_tab, so info
773 expression.h break works correctly. Also added "op_string", which
774 returns the string corresponding to the (enum exp_opcode)
775 opcode that is its argument.
778 Sat Jul 13 18:26:18 EDT 1991
780 coffread.c Added code to record the type of function arguments with
781 each paricular function. Code is very similar to that
783 dbxread.c Moved add_param_to_type() to symtab.c
784 symtab.[ch] Added function add_param_to_type() from dbxread.c
786 *** NOTE: The above additions have not been tested.
788 Mon Jul 15 12:50:47 EDT 1991
790 langauge.[ch] Added the functions type_error and range_error, which work
791 like error() except if the type/range mode is set to
792 *_mode_warn, then they do not do a return_to_top_level(),
793 but merely print a warning.
794 Also changed [set|show]_[type|range]_command() to support
795 the new "warn" feature.
797 Thu Jul 18 17:50:54 EDT 1991
799 mipsread.c Added code to record the type of function arguments with
800 each particular function. Code is very similar to that
803 *** NOTE: The above additions have not been tested.
805 Fri Jul 19 11:19:10 EDT 1991
807 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
808 UMIN_OF_SIZE, which when given a size of a numeric type,
809 return the maximum and minimum value it can hold. UMAX...
810 and UMIN... return the result for unsigned types.
811 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
812 struct types. They call above macros.
813 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
814 avoid a name conlict with the above.
815 c-exp.y Added range checking on numeric constants in
816 parse_number() for completeness.
817 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
818 return 0 if working_lang is not language_c.
820 Thu Aug 8 14:17:22 EDT 1991
824 breakpoint.c Documentation strings of some commands changed to
825 eliminate the references to the C language where
828 Tue Aug 13 15:48:03 EDT 1991
830 m2-exp.y Added qualified identifiers to the grammar. The semantics
831 are slightly different from those of the GDB operator ::
833 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
834 type_exp, where type_exp is any valid type expression.
836 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
837 printcmd.c Modified ptype_command() so it actually parses the input
838 (necessary for type expressions with scope qualifiers).
839 Added the function ptype_eval() which expects an
840 expression composed of one OP_TYPE element.
841 *.[ch] Replaced all occurences of parse_c_expression with
843 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
845 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
847 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
849 Small fixes from Peter Schauer:
851 * infrun.c (child_attach): Lint.
852 * solib.c (find_solib): Handle shared libs version 2.
854 Small fixes from David Wood:
856 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
860 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
861 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
863 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
864 chars_per_line is at maximum (user typed `set width 0'). Fix
865 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
867 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
869 * coredep.c: include ptrace.h where necessary.
870 * mipsread.c(parse_lines): fix unsigned char problem that was
871 messing up line numbers on SGI's and possibly other MIPS based
873 * infrun.c (child_create_inferior): use better test to check
874 return val from setpgrp().
875 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
876 for sgi/irix support.
878 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
880 * mipsread.c (parse_symbol): Put non-static procedures
883 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
885 Patch together `text_start' and `text_end' for 29K port.
887 * exec.c (exec_command): If NEED_TEXT_START_END, define the
888 variables and set them based on the exec file.
889 * am29k-tdep.c: declare text_start.
890 * valops.c (call_function_by_hand): declare text_end.
892 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
893 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
894 because machines that do this will also have to know to
895 set NEED_TEXT_START_END. Besides, it was a redundant way to
897 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
898 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
901 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
903 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
905 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
906 Pass MUNCH_DEFINE to munch whenever we run it.
907 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
908 format string; use 0x%x instead.
909 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
910 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
911 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
912 * inflow.c: Handle `short' process group IDs.
913 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
914 and check for ptrace errors.
915 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
916 (coff_symfile_init): Initialize text_bfd_scnum.
917 (read_coff_symtab): Use it to find the text [and absolute?] sections.
918 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
919 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
920 Merge target arm case with other "easy" cases. Add target
921 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
922 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
924 * minimon.h, remote-adapt.c, remote-mm.c: Add.
925 * munch: Cope with RT/PC putting fns in data segment.
926 Restore ability to override `nm' by specifying MUNCH_NM.
927 * xconfig/rtbsd, xconfig/ultra3: New host systems.
928 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
929 and remote-adapt. Remove encapsulated coff #define's (the
930 support should go in BFD, and gdb shouldn't know or care).
931 * tconfig/a29k-kern: Same, but for remote kernel debugging.
932 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
933 * tm-29k.h: Update BADMAG (though it should go away).
934 Allow the register definitions to be overridden in another
935 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
936 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
937 DUMMY_SAVE_GR96, for handling kernel calling conventions
938 that use GR64+ rather than GR96+.
939 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
940 remote debugging of Ultra3 kernel. Includes tm-29k.h and
941 overrides various things.
943 * remote-mm.c (mm_attach, mm_wait): Handle attach like
944 child_attach does, making a clean stop in the newly attached
948 * coffread.c: Make coffread independent of any particular
949 variant of COFF. Avoid #include-ing any particular one except
950 internalcoff.h. BFD now passes key values for symbol reading
951 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
952 and the symbol masks and shifts); use them.
953 Remove obsolete end_of_text_addr.
955 * exec.c: Remove unused include files.
957 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
959 * Makefile.in (documentation targets): Pass $(M4).
960 Bugfix from eggert@twinsun.com (Paul Eggert).
962 * stack.c (down_silently_command): Check for stack existence.
964 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
966 * Makefile.in (VERSION): Update to 4.0.3.
968 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
970 * core.c (core_file_command): Print frame at coredump with
971 its level number, by calling print_stack_frame.
972 * frame.h: Add selected_frame_level, print_stack_frame.
973 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
974 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
975 Change print_sel_frame and print_selected_frame callers to
978 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
979 * symfile.c (free_named_symtabs): Ditto.
980 * main.c (main): wrap_here needs an arg.
981 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
982 (solib_add): Avoid noise.
983 (solib_create_inferior_hook): Lint.
984 (sharedlibrary_command): Move dont_repeat to here.
985 * utils.c (error): Call wrap_here to force buffered output.
987 Small patches from Peter Schauer:
989 * coffread.c (start_symtab): Free any existing line_vector before
991 (read_coff_symtab): Ditto for type_vector.
993 * source.c (lines_to_list): New variable, replacing function.
994 (all uses): Use as variable.
995 (_initialize_source): Add 'set listsize' and 'show listsize'.
996 * utils.c (lines_to_list): Remove function.
997 * stack.c (print_frame_info): Use as variable.
998 * defs.h (lines_to_list): Remove declaration.
1000 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1002 * breakpoint.c (insert_breakpoints): Restore warning about
1003 the program might be running in another process, but only for
1004 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
1005 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
1007 * utils.c (error): if error_pre_print is set, print the string
1009 * main.c (main, print_gnu_advertisement, print_gdb_version):
1010 Reformat legalese so it always prints, but acts as an "I'm here"
1011 message while symbols are being read. If any errors occur,
1012 print a few newlines to set off the message and start it at the
1013 left margin. Remove mention of "help" command, and don't yak
1014 about symbol reading.
1015 (catch_errors): Error string is now printed first in case of
1017 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
1018 suggest the "help" command.
1020 * Makefile.in (VERSION): Set to 4.0.2.
1022 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
1024 * .gdbinit: Remove useless "rr" command. Set complaints
1025 to 1 for people debugging gdb.
1027 * breakpoint.c, remote-vx.c: Reword strings printed by
1028 catch_errors callers.
1030 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
1032 * WHATS.NEW: "history write -> history save". Doc "write on/off".
1033 (Fix from kenc@viewlogic.com.)
1035 Fix some infrastructure to be able to cope with host and target
1036 machines with different sized basic types (ints, ptrs, etc).
1037 (Idea from pierre@la.tce.com (Pierre Willard).)
1039 * values.c (value_from_longest): Rename from value_from_long.
1040 Handle pointer types as well as integers, so that targets with
1041 different pointer sizes from the host can be accomodated.
1042 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
1043 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
1044 uses of value_from_long to value_from_longest.
1045 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
1046 the correct pointer type to value_from_long{est}.
1048 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
1050 * remote-vx.c: Remove obsolete code for calling functions via
1051 vxworks kludge interface (it referenced value_from_long).
1053 * valops.c (value_string): Find malloc with lookup_misc_func, not
1056 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1058 Make writing to files work properly. (Fixes to BFD are also needed.)
1060 * core.c (core_open): Open file ourselves, read or r/w, depending on
1061 write_files. Use bfd_fdopenr.
1062 * gdbcore.h (write_files): New variable.
1063 * exec.c (write_files): Define variable, add set&show for it.
1064 (exec_file_command): Use write_files to open for read or r/write.
1066 Make shared library reading happen automatically. These changes
1067 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
1069 * inferior.h (stop_soon_quietly): Add to exported variables.
1070 * infrun.c (child_create_inferior): call solib hook, if defined.
1071 (child_attach): call solib hook, if defined.
1072 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
1073 (find_solib): Use lookup_misc_func rather than hand-rolled.
1074 (symbol_add_stub): New stub for catch_errors.
1075 (solib_add): Avoid output if !from_tty. Catch errors rather
1076 than just calling symbol_file_add and bombing.
1077 (solib_create_inferior_hook): Interface with the target process
1078 to let it read and alloc shared libs, then figure out what it did.
1080 * core.c (validate_files): Fix typo, soften warning.
1081 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
1083 * utils.c (fputs_demangled): Avoid duplicate printing if
1084 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
1086 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
1087 (Fix from pierre@la.tce.com (Pierre Willard).)
1089 * main.c (catch_errors): Change argument to a char * from an int,
1090 since a char * can point to a struct full of glop, but an int
1091 is not guaranteed to be able to hold a pointer.
1092 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
1093 breakpoint_re_set_one, breakpoint_re_set): Adapt.
1094 * core.c (core_open, solib_add_stub): Adapt.
1095 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
1097 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1099 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
1100 by adding .NOEXPORT target.
1102 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1106 * Makefile.in (VERSION): Roll to 4.0.
1107 (gdb.tar.Z): Make refcard.ps as well, for shipment.
1109 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1111 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
1114 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
1117 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
1119 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
1120 reflect above name change
1122 * WHATS.NEW: correct pointer to refcard.
1124 * doc/gdb.texinfo: update New Features, Installing
1126 * doc/gdbint.texinfo: add short description of configure +template
1128 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1130 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
1132 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
1134 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
1135 tar file, add dependencies for referenced doc files.
1137 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
1139 * coffread.c, symfile.c, stack.c: saberized.
1141 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1143 * doc/refcard.tex: permuted Essential Commands sec
1145 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
1147 set/show symbol-reloading
1148 default set complaints 0
1150 RET-repeat disabled after prompted long displays
1151 processID (attach) interpretation of 2nd GDB cmdline arg
1153 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
1155 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
1156 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
1157 breakpoint.c, main.c: lint.
1159 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1161 Install new configuration scheme for GDB and friends.
1163 * config.sub: Translate ordinary names to three-part names.
1164 * configure: Use three-part names internally.
1165 * configure.in: Translate three-part names to filenames.
1167 * README, WHATS.NEW: Update for gdb-4.0.
1168 * Makefile.in: Roll VERSION to 3.99.
1170 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
1172 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
1173 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
1174 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
1175 to single structures rather than arrays; when passing
1176 their address, use &. This avoids trouble with bdead compilers.
1177 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
1178 instead. This avoids portability headaches.
1179 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
1181 * source.c (open_source_file): Avoid ANSI const bdeath by
1182 skipping declaration and then casting result value.
1183 * tm-hp300bsd.h: Clarify comment.
1184 * utils.c (strstr): Result is const char *; ANSI bdeath.
1185 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
1186 since system include file defines it differently from "defs.h",
1187 though the two are equivalent for our purposes.
1188 * tconfig/hp300bsd: Add m68k-tdep.o.
1190 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1192 * tconfig/sun*4: Remove warnings about system assembler.
1194 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1196 * mcheck.c: Avoid warning about undeclared abort fn.
1197 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
1198 it causes recursive calls to error() when used in cleanups.
1199 To do so requires that we make it a function, so we do.
1200 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
1201 * utils.c (do_cleanups): Remove the current cleanup from the
1202 chain *before* calling it, in case error() is called from it.
1203 The result won't be pretty, but won't be an infinite loop either.
1205 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
1207 * dbxread.c (read_struct_type): Grok anon structs for C++.
1208 (vb_name, vptr_name): Null terminate these strings.
1210 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1212 Minor bug fixes from BSD Net2 gdb:
1214 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
1215 returns 0, there is no previous frame.
1216 * breakpoint.c (commands_command): If !from_tty, don't call
1217 input_from_terminal_p().
1218 * dbxread.c (record_misc_function): Speed up slightly.
1219 (compare_psymbols): Ditto.
1220 * infcmd.c (do_registers_info): Take a second argument to
1221 determine whether to print float registers. "info registers"
1222 does not do so anymore. "info all-registers" does, now.
1223 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
1225 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
1226 * inflow.c (initialize_inflow): Set tflags_ours correctly.
1230 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
1231 executing_breakpoint_commands if we are interrupted by error.
1232 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
1233 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
1234 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
1235 catch_errors() so we can setup the frame regardless of whether
1236 the shared libs work.
1237 * ieee-float.c (double_to_ieee_extended): Get exponent from
1238 right place in little-endian systems. From John Carey.
1240 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1242 * main.c: Remove unused terminating_signals and catch_termination().
1243 (long_options): Terminate with a zero element.
1244 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
1245 (gdb_readline): Make call-compatible with readline.
1246 (init_signals): Improve comments re vfork vs. signal.
1248 * utils.c (prompt_for_continue): Use new gdb_readline().
1249 If we prompt for continuation, we don't let CR repeat the previous
1250 command, once we get back to a prompt. It's too easy to keep
1251 hitting CR, expecting "--more--" prompts, and have some long
1252 command start repeating on you.
1254 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1256 * blockframe.c (frameless_look_for_prologue): Speed up by
1257 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
1258 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
1259 Define two variants, one faster.
1260 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
1261 and return zero, rather than giving an error.
1262 (setup_arbitrary_frame): Initialize the PC in the new frame.
1263 (skip_prologue): Add a second arg saying whether we're just
1264 checking for a frameless function or not.
1266 * core.c (core_open, core_close, core_xfer_memory): Move
1267 section table pointers and bfd* into the target_ops.
1268 (core_open): Allow errors in shared lib reading, etc.
1269 (core_files_info): Describe shared library sections.
1271 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
1272 exec_files_info, set_section_command): Move section table
1273 pointers and bfd* into the target_ops.
1274 (add_to_section_table): Add BFD to section table.
1276 * target.c (target_xfer_memory, target_info): Pass target to
1277 xfer_memory and target_info functions.
1280 * gdbcore.h: Move struct section_table.
1281 * target.h: New home of struct section_table.
1283 * solib.c (solib_add): New argument is the target_ops whose
1284 section list is to be added to, if any. Reallocate the
1285 sections in that target to add any that come from shared libs.
1286 (throughout) so_sections renamed to sections.
1287 (solib_xfer_memory): Deleted.
1288 * tm-sunos.h (SOLIB_ADD): Add target argument.
1289 (SOLIB_XFER_MEMORY): Delete.
1291 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1292 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
1293 from target_ops. It's the same on all targets. Add two section
1294 pointers to target_ops.
1296 * stack.c (find_relative_frame): Dump ancient algorithm for
1297 "down", just use handy "next" pointers.
1298 (frame_command): Don't error if there is no stack; let user
1301 * inflow.c (new_tty_prefork, new_tty): New prefork routine
1302 modifies static state in the parent process; new_tty itself
1303 runs in the child and modifies the child's file descriptors
1304 to match the saved static state.
1305 * infrun.c (child_create_inferior): Call new_tty_prefork,
1308 * infptrace.c (child_xfer_memory): Add ignored target arg.
1309 * remote-eb.c (eb_xfer_inferior_memory): ''
1310 * remote-nindy.c (nindy_xfer_inferior_memory): ''
1311 * remote-vx.c (vx_xfer_memory): ''
1312 * remote.c (remote_xfer_memory): ''. Rename from
1313 remote_xfer_inferior_memory.
1315 * main.c (main): Only try to attach "corefile" argument if
1316 it starts with a digit.
1318 * symfile.c (symbol_reloading): New "set/show" variable.
1319 (symbol_file_add): Shorten message about symbol reading.
1320 (add_symbol_file_command): Merge with add_syms_addr_command,
1321 since this should work on all targets now.
1322 (stop_whining): Default to zero, to shut up complaints
1323 about bad symbol tables on many systems.
1324 (free_named_symtabs): Just exit unless symbol_reloading.
1326 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
1327 and add comment explaining shared library screw.
1329 * source.c: #if defined => #ifdef.
1331 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1333 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
1335 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1337 * doc/rdl-apps.texinfo: provide default readline-appendix finder
1338 (doc/Makefile knows how to make one for local config)
1340 * Makefile.in: use doc/Makefile for doc targets
1342 * doc/Makefile: GDB documentation now has its own Makefile
1343 doc/refcard.tex: renamed from "gdbrc.tex"
1344 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
1345 doc/gdbint.texinfo: add markup in "Cleanups" chapter
1348 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1350 * values.c (baseclass_addr): When reading target memory, use the
1351 length of the basetype, not the upper type. We've only malloc'd
1352 enough space for the basetype, leading to errors in free().
1354 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
1355 ends up as a function specially, since we know the actual type of
1356 the pointed-to address. This (somewhat) fixes display of
1357 expressions that include misc_function_vector names. Try `cond 1
1358 !strcmp("a","b")' then `i b'.
1360 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
1361 The child can be proceeded from inside wait_for_inferior in
1362 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
1363 getting skipped in that case.
1365 * expprint.c (print_subexp): Use filtered output, since the
1366 subroutines we call use it, otherwise the output is horribly
1367 mangled, since output of wrappable stuff comes out late.
1369 * Makefile.in: Bump VERSION to 3.98.1
1371 * infrun.c (child_create_process): Use execlp to find the
1372 shell to exec our target program. This requires some fiddling
1373 with `environ' since there is no execlpe().
1375 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1377 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
1378 Minor rearrangement of refcard permits two new make targets--
1379 gdbrc.dvi DVI output for refcard, using CM fonts
1380 gdbrc.ps PostScript refcard, using PS fonts
1382 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1386 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
1387 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
1389 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1391 * doc/gdb.texinfo: last changes for release.
1392 Minor typo and formatting fixes; incorporated most fixes remaining from
1393 filed mail commenting on earlier drafts.
1395 Added warnings: pipes don't work in run command;
1396 conditions are converse of assertions;
1397 step over fn without debug info goes to next fn;
1398 vars may have "wrong" values near fn entrance, exit
1400 Added example from Kingston on printing repeated nonadjacent values
1402 Added explicit mention that in Emacs gdb mode C-c and C-z are like
1403 shell mode for signals
1405 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
1406 doesn't sound so much like its parent "Stopping and Continuing"; also
1407 moved entries on continue to top of section, so they don't get lost.
1409 Improved installation directions in appendix, added manual formatting
1412 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1414 * configure.in: Remove xm.h and tm.h even if we aren't linking
1415 new ones, so "./configure sun4; ./configure none" does the right
1416 thing. Assume that alldeps.mak and depend are already built in
1417 srcdir, and avoid running "make" (particularly "make depend",
1418 which involves "gcc") from inside configure. Build Makefile
1419 directly rather than building Makefile.conf first.
1420 * configure: Regenerate with above changes.
1421 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
1422 to 3.98. Revise gdb.tar.Z procedure to produce a file
1423 called gdb-$(VERSION).tar.Z but which unpacks into a
1424 directory called "gdb". Move non-source files out of
1425 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
1426 (depend): Don't try to do "gcc expread.y".
1427 (expread.o): Update dependencies by hand.
1429 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1432 Fixed a variety of small typos that prevented info from formatting
1433 cleanly; altered too-long heading for GPL Appendix, as discussed
1434 w/RMS; Changed date on cover to July 91.
1436 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1439 (1) Applied some fixes due to comments from Larry Breed (easier ones
1440 through chapsec 5.2)
1441 (2) Eliminated use of @footnote---had my doubts about it anyways, and
1442 it's broken in latest texinfo
1443 (3) Introduced *some* use of [] for optional arguments, where
1444 explanation is not simpler by listing cmd w arg and cmd w/out arg
1445 separately. Still not using @deffn.
1446 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
1447 couple of headings are too long. Need patches to texinfo or revision
1450 * Partial update to README (which still needs work for this
1451 release!): (1) use of configure corrected for new script,
1452 (2) "make gdb.dvi" and "make gdb.info" mentioned.
1454 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
1456 * symtab.c (lookup_symbol): Don't complain right off about
1457 no debug symbols; use the misc function vector first.
1458 (list_symbols): Use misc function vector to find symbols
1459 that don't have debug info, and print them.
1460 (find_pc_symtab): Temporarily avoid fatal() when psymtab
1461 PC range doesn't match symtab PC range, as it does on the
1462 MIPS because our symtab reading isn't perfect.
1464 * dbxread.c (dbx_symfile_read): Make warning about
1465 "no debug symbols" slightly nicer.
1467 * source.c (select_source_symtab): If "main" symbol exists,
1468 but decode_line_spec can't find line info, don't just return
1469 a zero; try other source symtabs or give an error.
1471 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
1472 their low addresses first, then rip through fixing high addrs.
1474 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
1475 <runene@ifi.uio.no>.
1476 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
1478 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1480 * Minor, mostly mechanical, cleanup of doc subdir for clean
1481 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
1482 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
1484 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
1486 Mostly MIPS and general symbol-reading fixups.
1488 * doc/gdbint.texinfo: Add documentation on symbol-reading
1491 * mipsread.c: Remove kludges around #include "ecoff.h".
1492 Remove redefinitions of a_magic, etc, no longer used.
1493 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
1494 Fix global overview comments to match symfile.c protocol.
1495 (mipscoff_new_init): Eliminate cur_hdr if we have one.
1496 (mipscoff_symfile_read): Eliminate unused code. Avoid
1497 sorting all the symtabs, when all we have read here is psymtabs.
1498 The symtabs are sorted as they are created anyway. Tell
1499 condense_misc_bunches whether we're mainline.
1500 (psymtab_to_symtab_1): Pass filename when recursing, to make
1501 stack trace more informative.
1502 (parse_partial_symbols): Assume cur_hdr as argument.
1503 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
1504 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
1505 the TYPE_NAME of char *, since that's done in symfile.c.
1506 (free_numargs, parse_symbol, add_symbol, add_block,
1507 shrink_linetable): Declare these fns void.
1508 (upgrade_type): Convert tree of if's to switch. Clean up
1509 bogus "off == 0" handling with a complaint. Avoid setting
1510 field bitpos and bitsize of array with lower and upper bounds.
1511 Check specified bitsize of elements against their actual type's
1512 bitsize, and complain if different. Complain about unknown
1514 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
1515 (psymtab_to_symtab_1): Print names of subsidiary files that
1516 are being read in. FIXME, we read far too many files. This code
1517 is not the problem, the problem is in parse_fdr where the psymtabs
1519 (cross_ref): Result should indicate that we used one aux entry
1520 normally, or two if we encountered a "next" entry. This used
1521 to leave the caller pointing at the wrong aux entry.
1522 (add_symbol): If overflowed cur_block, reallocate it larger,
1523 chase all pointers to it, and complain(), rather than clobber memory.
1524 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
1525 (new_field): Only allocate one field initially, not two.
1526 Pull ++ out of macro argument. Simplify.
1527 (_initialize_mipsread): Avoid initialization of importd
1528 global_psymbols and static_psymbols.
1530 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
1531 to properly set pst->symtab; avoid searching for it.
1532 (symfile_fns): Improve comments, add a FIXME.
1533 * dbxread.c: Update comments to reflect symfile protocol.
1534 (read_ofile_symtab, end_symtab): Return the symtab.
1535 (psymtab_to_symtab_1): Set pst->symtab.
1537 * coffread.c (coff_symfile_read): tell condense_misc_bunches
1538 whether we're mainline.
1540 * symfile.h (sym_fns): Remove unused sym_discard member.
1541 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
1543 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
1544 the environment variable is not.
1545 * infcmd.c (finish_command): Use filtered printfs.
1546 * cplus-dem.c: Add struct tags to a few unnamed structs.
1547 * valops.c (value_coerce_array): Improve comments.
1548 * valprint.c (type_print_varspec_suffix): Print array size only
1549 if greater than zero.
1550 * m88k-tdep.c: Shift some lines left by one space, that had
1551 apparently been trashed at some point.
1552 * TODO: More things to do, a few got done.
1554 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1556 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
1557 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
1559 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
1560 * expread.y, findvar.c, symmisc.c: Ditto.
1561 * printcmd.c (address_info): Update printed forms of LOC_
1562 symbols. Elim LOC_EXTERNAL.
1563 (print_frame_args): Keep track of param stack offsets before
1564 re-looking up to find the local register param is kept in.
1566 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
1567 Further integration of mipsread into gdb. Eliminate unused
1568 routines, duplicate declarations. Handle static symbols in
1569 psymtabs as well as external symbols. When reading symtabs,
1570 insert symbols into the correct block (global, static, or a local
1572 (read_mips_symtab, parse_partial_symbols): Don't pass useless
1574 (mipscoff_symfile_read): Don't call select_source_symtab.
1575 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
1576 rather than SYMBOL_VALUE.
1577 (parse_external): Comment clobbering of top_stack.
1578 (parse_partial_symbols): Update comments. Allocate and parse
1579 static symbols as well as external symbols. FIXME, enum values
1580 are not handled in this pass, but should be. Inline new_psymbol.
1581 Use SYMBOL_VALUE_ADDRESS.
1582 (psymtab_to_symtab_1): Read symbols into global static block
1583 by default (until enter some function's local block context).
1584 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
1585 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
1587 * source.c (select_source_symtab): Select a source symtab
1588 from either the symtabs or, failing that, the psymtabs.
1589 (list_command): Update error message.
1590 (forward_search_command, reverse_search_command): Use getc, not
1591 fgetc, for speed. FIXME, add comment about buffers that die if
1592 overrun by long line.
1594 * values.c (unpack_field_as_long, modify_field): Avoid shifting
1595 by an entire word, which is not portable, if we have a 32-bit
1596 field. (Code in dbxread.c already turns such bitfields, if
1597 aligned, into ordinary ints, but fixing this will help for other
1598 symbol formats and for future changes.)
1599 * core.c (core_open): Handle ANSI const brain death.
1600 * utils.c (vprintf): Fix varargs typo.
1602 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1604 * findvar.c (find_var_value): Handle &function better.
1605 * TODO: Document work needed on &fn and &array.
1606 * printcmd.c (print_address_symbolic): New arg is the prefix
1607 to print if a name is printed.
1608 (print_address_demangle): Honor "set print address" now.
1609 Use new arg above to improve spacing of output.
1610 * valprint.c (val_print): When printing function pointers,
1611 print symbolic form too.
1612 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
1614 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1616 * core.c (memory_error): Reword error msg to mislead less.
1618 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
1620 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
1621 parse_partial_symbols): Use newer BFD internals (external_filehdr
1622 and external_aouthdr), byte-swap the fields that we care about
1623 before using them, and make the file header data local to
1624 read_the_mips_symtab rather than global.
1626 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
1628 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
1629 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
1631 * main.c (command_line_input): Flush stdout and stderr
1632 before every call to readline. This reportedly fixes a bug
1633 that comes up in Sys V running emacs-gdb and/or xxgdb,
1634 when stdin/out are pipes or sockets.
1636 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1638 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
1639 Avoid declaring Makefile dependencies, because GNU Make stupidly
1640 tries to update it if we do.
1642 * coffread.c: Revise for minor changes to bfd internal coff
1645 * configure: If -template= is given a relative path, make it
1646 absolute before recurring in subdirectories.
1648 * configure, configure.in, Makefile.in: Install "configure" script
1649 as replacement for config.gdb.
1650 * config.gdb, Makefile.dist, Makefile.sdir: Remove
1651 * README: Update for configure, mostly. FIXME.
1653 * Add dec3100 as equivalent to littlemips. Indicate in all host &
1654 target config files that they are for the host. When the lines
1655 get copied into the Makefile, this makes it more obvious what's
1658 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1660 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
1661 tabs, which end up in the disassembler output inadvertently.
1663 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1665 Make it compile cleanly in an ANSI GCC2 environment.
1667 * blockframe.c: <stdio.h>
1668 * cplus-dem.c: free takes a void *, ifdef __STDC__
1669 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
1671 * defs.h (alloca): Avoid doing anything if alloca already def'd.
1672 * stddef.h, stdlib.h: Remove these files.
1673 * symtab.c: Avoid declaring qsort, close.
1674 * symfile.c: Avoid declaring close.
1675 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
1676 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
1678 Assorted other changes.
1679 * dbxread.c: include "libaout.h", not "liba.out.h".
1680 * printcmd.c (print_frame_args): Set recurse properly for
1681 indentation of struct and array parameters.
1682 * valops.c (value_cast): Allow cast to void.
1683 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
1684 single_step() in a target-independent fashion.
1685 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
1686 set up to be ready to continue. This makes us target independent.
1687 * infptrace.c (child_resume): Remove call to single_step; now
1688 can single step a SPARC target of any kind.
1690 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1692 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
1693 docn into separate sections---basically chapters, plus two loose
1694 pieces that can be configured to go in different places. This
1695 allows GNU m4 to preprocess the manual without coredumping.
1697 * Makefile.dist: tell TeX where to find texinfo.
1699 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1701 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
1702 the new target "rdl-apps.texinfo" which captures the Makefile
1703 variable that records where to find the Readline libraries.
1705 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
1707 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
1708 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
1709 * defs.h (const, volatile): Only define if not already defined.
1710 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
1712 * README: Update for release 3.95.
1713 * config.gdb: Don't create readline dir in subdir builds.
1714 * main.c: Include with "..." form for non-system include files,
1715 so "gcc -MM" for "make depend" works.
1716 Include readline files with "...h" rather than <readline/...h>.
1717 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
1719 * coffread.c: Undo minor damage done by Rich Pixley. Use
1720 different internal and external representations of COFF
1721 data structures. Use new BFD routines for swapping them in and
1723 * symfile.c (free_named_symtabs): Avoid freeing file names that
1724 are null or empty. Old i960 tools seem to produce files that
1725 claim to have empty names, causing each successive file read
1726 to blow away the previous one.
1727 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
1728 Move deferred_stores to top of file, but don't separate its
1729 #define's from its variable. Add commentary.
1730 * Makefile.dist: Fix Rich damage; undo "configure" changes in
1731 favor of keeping the (working) config.gdb. Move readline
1734 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
1736 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
1738 * infptrace.c (fetch_registers): no result, since now void.
1739 * tconfig/news: target depends on m68k-tdep too.
1741 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1743 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
1746 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
1747 applied various small fixes due to or inspired by RMS comments
1749 * doc/gdb.texinfo: finished using all RMS comments, save those for
1750 appendices on readline and cmd history (which are in other source
1753 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1755 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
1756 chapter 9; (2) documented 'break' command's menu mode for
1757 overloaded names, in response to hgs problem report C++ p-31
1759 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1761 * doc/gdb.texinfo: (1) better introductory example; (2) more
1762 consistent use of @code, @samp, @file, @kbd throughout; small
1763 cleanups to first three nodes; (3) new "Contributors" node;
1764 (4) Appendix, Renamed Commands; (5) divert specialized startup
1765 instructions to "Targets" chapter for generic manuals, while
1766 leaving them up front for manuals specific to specialized
1767 environments; (6) apply fixes from RMS comments through chapter 4.
1769 * pretex.m4: modify explanatory text slightly (and redefine
1770 "regexp") to keep GNU m4 from complaining. (It still crashes
1771 later, but one step at a time...)
1773 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
1775 * readline/readline.c (update_line): Avoid dereferencing a pointer
1776 before comparing it to its bounds. Saber caught this.
1777 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
1778 and only set PC if tgetstr returned non-null. Saber caught this.
1780 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1782 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
1783 stuff for config manual) here where it counts; updated
1784 to use new subdir structure (gdb/doc/).
1786 * Makefile: generated from above via
1790 * gdbint.texinfo: added instructions on generating gdb.info* files
1791 locally for release. These are ordinary info
1792 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
1793 Makefile)---but due to use of texinfo 2, can't count on makeinfo
1794 to generate these, so we distribute them already formatted.
1796 * gdb.texinfo: included full Info node and menu crud (as generated
1797 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
1799 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
1800 put in comments-for-future gdb.info target (one day makeinfo will
1803 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1805 * gdb.texinfo: Updated to include new or old undocumented
1806 commands, at least the following (perhaps some others I forgot to
1807 record): info f, info float, info path, info program, info s, info
1808 set, info source, info terminal, info types, info user, set/show
1810 Also covered all recent GDB command renames for v4.
1812 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1814 * mipsread.c: Rather than keeping count of how many symtabs
1815 and psymtabs we have, for sorting purposes, count them when
1816 we need to sort. This fixes bug in rereading of symbol tables.
1818 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1820 * infcmd.c: renamed "info path" to "show paths"
1821 * gdbrc.tex: documented above.

1831 Fix up "saber_gdb" to work again.
1832 * saber.suppress: Update.
1834 * coffread.c, exec.c, infptrace.c, inftarg.c, remote.c, solib.c,
1835 symtab.h, target.c, target.h: Lint.
1836 * core.c: setup and select frame after reading shared libs,
1837 else reading shared libs will clobber them. Lint.
1838 * utils.c (error): Force out any buffered wrap text.
1840 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1842 * remote.c: Remove decls of memory_insert_breakpoint
1843 and memory_remove_breakpoint, no longer used. (Suggestion of
1846 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
1847 to make it easier to interface to "configure"'d libraries.
1849 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
1851 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
1852 aliases for set/show print.
1854 Thu May 2 11:22:02 1991 Jim Kingdon (kingdon at cygint.cygnus.com)

1908 * coffread.c [TDESC]: Move setting of debug_info from
1909 coff_symfile_read to find_linenos and make it work with BFD.
1911 * cplus-dem.c [__STDC__]: Make x{m,re}alloc return void*.
1913 * signame.c: Cast const char* to char* when assigning to sys_siglist.
1915 * utils.c (strsave): Make arg const char* not char*.
1917 * infrun.c (wait_for_inferior) [SHIFT_INSN_REGS]: Use
1918 bpstat_explains_signal (stop_bpstat) not stop_breakpoint.

1938 Mips bringup and general cleanup
1940 * cplus-dem.c: Move CPLUS_MARKER define to after defs.h.
1941 * infptrace.c (PT_WRITE_D, PT_READ_D): Use correct values.
1942 (This still doesn't seem to make MIPS bkpts work.)
1943 * mipsread.c: Remove dup "Reading symbol data..." msg.
1944 (symbol_file_command, add_file_command): Remove, obsol.
1945 * printcmd.c (ptype_command): Say "an enum" rather than "a enum".
1946 Wrap output appropriately.
1947 * stack.c (locals_info, catch_info, args_info): Check
1948 selected_frame rather than target_has_stack or coredumping.
1949 * valprint.c (type_print_varspec_suffix): Wrap "ptype" output of
1950 enums appropriately.
1952 Wed May 1 14:10:22 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
1954 * signame.c: Include defs.h and param.h.
1956 * cplus-dem.c: Include defs.h and param.h.
1957 Makefile.dist: Don't hack in the "param.h".
1958 param.h: Don't include defs.h.
1960 * expread.y: Use a union to deal with the fact that type_stack
1961 can have both ints and enum type_pieces in it.
1962 ({push,pop}_type_int): New functions.
1964 Tue Apr 30 13:18:58 1991 Jim Kingdon (kingdon at cygint.cygnus.com)

1976 symtab.c, cplus-dem.c, value.h, expread.y, valprint.c,
1977 copying.awk, solib.c, inflow.c, symmisc.c
1978 : Lint. Use read_memory not read_memory_integer on CORE_ADDR's.
1979 Use {value_as,unpack}_pointer (added to values.c)
1980 not {value_as,unpack}_long on CORE_ADDR's.
1981 Use longest_to_int (added to defs.h) instead of cast to int.
1982 Remove from_tty arg to mod_path.
1983 Put symfile_bfd in {coff,dbx}read.c not symfile.h.

2453 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
2454 is the first symbol read, even if not mainline.
2455 (dbx_psymtab_to_symtab): symfile might be zero, cope.
2456 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
2457 (set_section_command): New command ("section xxx yyy" -- should
2458 be renamed to "set section xxx yyy" FIXME) which sets the
2459 base address of a section of the exec file, overriding the
2460 virtual address that BFD reports.
2462 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2464 * exec.c: Add add_syms_addr_command to exec_ops, so you can
2465 load symbols at any address while examining an exec file.
2467 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
2469 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
2470 for printing the float info is host-dependent, not
2471 target-dependent. FIXME.
2472 * i386-pinsn.c: Move #includes to top, remove useless ones.
2473 * i386-tdep.c: Don't bother including <.../reg.h> since we
2474 don't use it (and it doesn't exist on host systems).
2476 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
2477 Convert negative numbers properly.
2478 (ieee_test): Make numbers really random; fix format arg.
2480 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
2481 * core.c (core_detach): Unpush core_ops, which might not be on
2482 top. We used to just pop the top, which broke things. Don't
2483 need dont_repeat() any more.
2484 (core_file_command): Psst! Don't repeat it.
2485 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
2486 * expprint.c (print_subexp): Avoid switch fallthru on
2487 BINOP_ASSIGN_MODIFY, so we can print += and such.
2488 * frame.h: Fix typo.
2489 * inflow.c (kill_command): After killing inferior, print our
2490 current frame in the core file, if we have one.
2491 (generic_mourn_inferior): When inferior dies, either select
2492 the current frame (in the new target, e.g. core file), or
2493 set both the current and selected frames to NULL.
2495 Changes from Peter Schauer.
2497 * infptrace.c: Avoid <sys/ptrace.h> on USG.
2499 * Make all file names fit in 14 characters (sigh and damn!):
2500 mv hp300hpux-xdep.c hp300ux-xdep.c
2501 mv symmetry-xdep.c symm-xdep.c
2502 mv symmetry-tdep.c symm-tdep.c
2503 mv convex-opcode.h convx-opcode.h
2504 mv tm-vxworks960.h tm-vx960.h

2508 mv remote-sa.m68k.shar rem-m68k.shar
2509 mv remote-multi.shar rem-multi.shar
2510 * Makefile.dist, README, config.gdb, convex-pinsn.c,
2511 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
2512 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
2515 * command.c (user_info_1, user_info): New command for listing
2516 the user-defined commands.
2518 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
2520 * dbxread.c (really_free_pendings): Clear file_symbols
2521 and global_symbols after freeing them; otherwise, running
2522 this function twice (if it appears twice on the cleanup
2523 chain), we try to free things twice.
2525 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
2526 based on text_addr (the address of text in core), not on addr (the
2527 offset between text in the .o file and in core). This change
2528 is from Peter Schauer.
2530 * main.c: Define ALL_CLEANUPS as a cast of zero.
2531 (return_to_top_level): Use it.
2532 (main): Do all cleanups after each command run as part
2533 of the gdb startup sequence. Also do all cleanups before
2534 entering the command loop, and every time we exit the command
2535 loop and reenter. Before, the cleanups from the startup sequence
2536 were being left undone until the first error!
2537 (command_loop): Rename do_nothing cleanup to command_loop_marker
2538 so we can see it easily when examining the cleanup chain.
2539 (init_signals): Add another do_nothing for signal handling.
2540 (quit_command): Only try to kill target if it has execution.
2541 Problems in the target stack got us into a state where
2542 inferior_pid was nonzero but none of the targets had execution.
2543 In this state you couldn't exit gdb.
2545 * dbxread.c: Two changes from Peter Schauer.
2546 (echo_command): Fflush output after an echo command.
2547 (show_history): Pass all args to cmd_show_list.
2549 * utils.c (init_malloc): Call mtrace to turn on tracing
2550 if the environment variable MALLOC_TRACE is set to a file name.
2551 * mtrace.c: Add source file which provides a log of every malloc,
2552 free, and realloc to a trace file.
2553 * mtrace.awk: Add source file which analyzes the trace file.
2554 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
2555 (VERSION): Roll to 3.94.3.
2557 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
2558 (check_duplicates): Don't bother with watchpoints.
2559 (set_raw_breakpoint): Comment about danger of this routine.
2560 (watch_command): Parse and eval all args before calling
2563 * solib.c (find_solib): Avoid error in referencing memory to
2564 see if any more shared libraries have been added. This is
2565 particularly useful if the target has terminated. Bug reported
2568 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
2569 in bringing up 3.94.2 on the Sun-3.
2571 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
2572 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
2573 expression (in scope) before reenabling watchpoint.
2574 * signame.c (init_sigs): Add missing declaration of i, fix
2575 sys_siglist declaration.
2576 * source.c (list_command): Fixed range computation to use
2578 * stack.c (backtrace_command): Do not allow command if target has
2579 no stack, print informative error message.
2580 * target.c (target_command): Do not write into command line
2581 because this fails if the target command is used in a user defined
2582 command. [This change was enhanced by gnu to support any-
2583 unique-prefix matching on target names.]
2584 * valops.c (value_struct_elt): Avoid infinite loop on an
2585 erroneous attempt to print the member of function (try p main.p).
2587 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
2589 * expread.y (name_no_typename): Avoid reduce/reduce errors
2590 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
2591 Since the GDB parser really doesn't use name_no_typename in a
2592 name-only context, the parser can't tell the diff between
2593 names and numbers here. Avoid allowing a name_no_typename
2594 to be a NAME_OR_*INT to resolve the conflict.
2596 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2598 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
2600 * valprint.c (val_print_fields): bitfield printing didn't handle
2601 byte order. Indirect through a few more fns to cope.
2603 * values.c (modify_field): also cope with byte order.
2605 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2607 Cleanup for release 3.94.2:
2609 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
2610 include files. Roll version to 3.94.2.
2612 * coffread.c (init_stringtab): Read length into unsigned char
2613 array before swapping; don't assume 32-bit longs.
2615 * target.c (target_info): Don't bother with get_sym_file, just use
2616 the symfile global variable.
2617 * symtab.h, symfile.c (get_sym_file): Delete it.
2619 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
2620 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
2621 (read_type): Replace one more error() with complain().
2623 * mipsread.c (parse_partial_symbols): Replace printf with complain.
2625 * i960-tdep.c: Fix copyright attribution.
2627 * config.gdb: Quote all backquotes in doublequotes. You can
2628 quote me on that. BSD 4.4 shell found this one.
2630 * infptrace.c (throughout): The third argument to ptrace is an
2633 * infrun.c (wait_for_inferior): When program has terminated, we
2634 have to call target_terminal_ours before we pop that target off
2635 the stack (e.g. before a call to target_kill or
2636 target_mourn_inferior). This fixes problem where a program
2637 terminates, then GDB stops for (tty output) and you have to type
2638 "fg" to the shell to resume it. FIXME: This code for what to
2639 do after termination really should be in normal_stop instead.
2641 * gdbcore.h (read_memory_check): Change declaration; it changed
2644 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
2645 4.4 prereleases, this avoids a bug in their sgtty compatability
2647 * remote.c: Use terminal.h rather than hand-rolling the same.
2649 * signame.c, signame.h (psignal): Arg is unsigned, not int.
2650 * utils.c (strsave, strstr): Fix arg types.
2651 * valprint.c (val_print): lint
2653 MIPS symbol table support from Per Bothner:
2655 * symfile.c (symtab_fns): Remove initializer table that needs to
2656 be hacked for each new symbol file format supported.
2657 (add_symtab_fns): New function, chains symbol table
2658 handlers into the global list.
2659 (symfile_init): Search this list.
2660 * symfile.h: Add next pointer, declare add_symtab_fns.
2661 * coffread.c (_initialize_coffread): Call add_symtab_fns.
2662 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
2664 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
2665 symbol *). Thus, we no longer need the hack to trash
2666 pst->filename. Good, since that hack confused code in symfile.c!
2668 (reorder_symtabs, destroy_all_symtabs): Removed static
2669 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
2670 Instead, the latter now uses a temporary array (stack-allocated
2671 from an obstack, and then freed).
2673 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
2674 haven't been set in the outermost stBlock of a procedure. This was
2675 a problem with f77 binaries on Ultrix 4.?.
2677 (new_symtab, new_symbol, new_type): Continue changing code to use
2678 obstacks more and otherwise conform to dbxread internal style.
2679 Made the free_code of symtabs be free_linetable (as in dbxread)
2680 instead of free_contents. This implies memory leaks when reading
2681 a new symbol table, until the conversion is finished. Did change
2682 (struct symbol) and (struct type) to be allocated on the
2683 symbol_obstack. Blocks and blockvectors are among the things
2686 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
2687 tested much, but it solved one problem (reported by Meissner), and
2688 cleans up some other things. The problem happened when an
2689 included file contains actual code (functions) and not just
2690 definitions. The mips coff is a little inconvenient there, since
2691 it may cause a procedure to be mapped to the wrong psymtab.
2693 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
2694 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
2695 this will need work for the new core paradigm.
2697 Opcode patches from the net:
2699 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
2700 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
2701 missing altogether - they are added here. From Bruce Bauman.
2702 * mips-opcode.h: The low mask for C0 instructions was too small.
2703 From Garrett Lau. I modified the fix to check the entire 32-bit
2706 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
2709 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2711 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
2713 * dbxread.c (read_type): Pointer subtraction (value_sub in
2714 valarith.c) sometimes failed because the types of the
2715 pointers being subtracted were not identical.
2716 These differed because dbxread.c was allocating pointer types
2717 using dbx_alloc_type+smash_to_pointer_type instead of
2718 lookup_pointer_type. I failed to find a justification for the
2719 former, so I changed it to use the latter. Similarly, I
2720 replaced smash_to_function_type by lookup_function_type,
2721 and smash_to_reference_type by lookup_reference_type.
2723 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
2724 _initialize_mipsread): corresponding changes.
2726 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
2728 * source.c (mod_path): Do tilde_expand on each component of the path,
2729 rather than on the (list of) paths as a whole.
2730 (print_source_lines): Set first_line_listed in addition to
2731 current_source_symtab and current_source_line. If the source was
2732 not findable, after a "dir" command to fix the problem,
2733 a "list" would get the wrong lines.
2735 While I was there... (gnu):
2737 * dbxread.c (read_type): Change error to complaint.
2739 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2741 First attempt at detailed understanding of symbol table memory alloc.
2743 * dbxread.c (dbx_symfile_read): Free our string table if we
2744 aren't the mainline. Free the "info" struct since we're done with
2746 (init_psymbol_list): Free any previously allocated psymbol lists.
2747 (): FIXME: Should realloc-down the psymbol lists when done reading
2748 the main symbol file?
2750 * symmisc.c (free_symtab): Free fullname field too.
2752 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
2753 (REGISTER_ADDR): Make result type unsigned int.
2755 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
2756 define REGEX must also define REGEX1 (its dependency).
2758 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
2760 * tconfig/i960: No longer works, points you at vxworks960 or
2763 * xgdb.c, XGDB-README: Remove file. Users can get the much
2765 * Makefile.dist: Remove all trace of xgdb.
2767 * breakpoint.c (breakpoint_1): Pass demangle arg to
2768 print_address_symbolic.
2769 (clear_breakpoints): Remove unused function.
2770 (breakpoint_re_set_one): Guts of breakpoint_re_set.
2771 (breakpoint_re_set): Use catch_errors to do them all anyway.
2773 * gdb-int.texinfo (Host versus Target): Add section on what is
2774 a "host" feature versus what is a "target" feature.
2776 * infcmd.c (path_command, path_info): Handle the PATH variable
2777 (object search path) as conveniently as the source search path.
2778 * environ.c (set_in_environ): Set some vars in GDB's environment,
2779 in addition to the child's. PATH, G960BASE, G960BIN for starters.
2780 * source.c (mod_path): New function, from guts of
2781 directory_command, modifies a path. Used by path_command.
2782 (directory_command): Call it.
2783 * defs.h (strsave): Declare.
2785 * utils.c (sevenbit_strings): Add new printing option.
2786 (printchar): Use it.
2787 (strsave): Provide this handy helper routine.
2788 (set_width_command): Rename set_screen_width_command.
2789 (_initialize_utils): "set screen-width" => "set width";
2790 "set screen-height" => "set height"; add sevenbit-strings.
2792 * infcmd.c (do_registers_info): Print floating point registers
2793 in raw hex as well as float format, regardless of whether it is
2794 a "virtual" convertible register.
2795 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
2796 regs as a double, just in case it's being used that way.
2797 * values.c (unpack_long): Comment on array/function coercion.
2798 (unpack_double): Argument is in target byte order now. For
2799 integer arguments, just call unpack_long and float the result.
2800 * m68k-tdep.c: include defs.h for "const" handling.
2801 * remote-nindy.c: Use ieee-float stuff.
2802 (nindy_fetch_registers): Unpack double regs to host double, then
2804 (nindy_store_registers): Pack extendeds to host double, flip
2805 around by misusing unpack_double, send as target double.
2807 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
2808 zero, as when stopped at the first instruction of a process.
2810 * blockframe.c: Fix filename in comment (param.h => tm.h).
2811 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
2812 * tm-68k.h: Fix typos.
2814 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
2816 Changes from a bringup on the DEC Vax under Ultrix 4.0.
2818 * coredep.c (fetch_core_registers): Pass end-address of register
2819 section to register_addr as expected. Don't call supply_register
2820 if we'd just pass it garbage.
2822 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
2824 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
2826 * target.c (push_target, target_info): Cast enums to int for < or
2829 * stack.c (print_frame_info): Identify source file & line
2830 even if we can't print it.
2832 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
2834 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
2836 Clean up IEEE floating point support.
2838 * ieee-float.h: New file.
2839 * ieee-float.c: Write real routines to convert between host
2840 doubles and various target IEEE extendeds.
2841 * m68k-xdep.c: Eliminate assembler code for extended floats.
2842 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
2843 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
2844 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
2845 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
2846 double_to_ieee_extended.
2847 * i960-tdep.c: Define ext_format_i960.
2848 * m68k-tdep.c: Define ext_format_68881.
2849 * sparc-tdep.c: Define ext_format_sparc, though unused.
2850 * Makefile.dist (HFILES): Add ieee-float.h.
2851 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
2854 Obsolete the "coffstrip" program in favor of using BFD's strip.
2856 * nindy-share/coffstrip.c: Remove file.
2857 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
2858 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
2859 * tconfig/nindy960: Remove reference to coffstrip.o.
2861 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
2863 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
2865 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
2866 * dbxread.c: Remove static symfile_bfd.
2867 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
2869 * inftarg.c (child_detach): Pop the child_ops vector if the
2870 detach is successful.
2871 * remote-nindy.c (nindy_create_inferior): Don't push a new
2872 nindy_ops since nindy uses the same one for execution and memory
2874 * core.c (core_ops): Use child_attach and child_create_inferior
2875 rather than default attach and create_inferior functions.
2877 Handle floating point registers in core files.
2879 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
2880 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
2881 This version untested since BFD doesn't yet support sun3 core
2883 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
2884 conventions. Fix comments and style. This version has not
2885 been compiled yet, since we have no HP inhouse.
2886 * core.c (get_core_registers): Look for two sections, ".reg"
2887 and ".reg2", and pass both to fetch_core_registers sequentially.
2889 Revise directory path yet again.
2891 * source.c (forget_cached_source_info): Not static any more.
2892 (init_source_path): New default source path is "$cdir:$cwd".
2893 (dir_command): Handle variable arguments ($cdir, $cwd).
2894 (source_info): Print "Compilation directory" rather than
2895 "Originally compiled in" to remind people of $cdir.
2896 (openp): If the path contains $cwd, use current directory.
2897 (open_source_file): If compilation directory is known, replace
2898 first $cdir in path with the compilation directory.
2899 (print_source_lines): Even if we can't print the lines, set the
2900 current symtab and line for future commands like "info source" or
2901 "breakpoint". Also, error message now contains the file name,
2902 line number, and file access error message.
2903 (_initialize_source): Fix help text to describe changes.
2904 * main.c (cd_command): Forget cached source info when we chdir.
2905 * utils.c (strstr): Add simple implementation.
2907 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
2909 * coffread.c (read_one_sym, init_linetable, init_stringtab):
2910 Byte-swap COFF symbol tables if necessary when reading them in.
2911 Use complain() to replace error message in one spot. Needs
2912 corresponding change in bfd/coff-code.h to make some symbol
2913 swapping routines non-static.
2915 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
2917 Merge changes from Eirik Fuller, for UTek.
2919 * defs.h (errno): Add declaration.
2920 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
2921 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
2922 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
2923 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
2924 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
2925 declarations of errno.
2927 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
2929 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
2930 <rpc/rpc.h> and <rpc/types.h>.
2932 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
2934 * i960-tdep.c (examine_prologue): Add new argument limit,
2935 which stops the scan at the end of the prologue, or at the PC.
2936 This fixes a problem where it walks down into the code for the
2937 user's statements if that code looks like function prologues.
2938 Mark Fox and I have been bouncing this code back and forth, making
2939 small changes to it. Callers changed to match.
2941 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
2943 Cleanup for gdb-3.94 release final:
2945 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
2946 the .c files from vx-share and nindy-share, from the various
2947 macros, since they are not found via ALLDEPFILES.
2948 (SFILES): Add tm-i960.h.
2949 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
2950 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
2952 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
2953 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
2955 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
2957 * am29k-tdep.c: Add contribution line.
2958 (examine_prologue): Cache information about function prologues in
2959 the misc-function-vector to avoid lots of references over the
2960 serial line while examining instructions.
2962 * core.c (core_close): New function made from cleanup_core.
2964 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
2965 remote-vx.c, remote.c, target.c, target.h,
2966 Update target_ops vector to add attach, close, and load entries.
2967 Use add_syms_addr_command, not add_file_addr_command, for
2968 add_file. Break out close routine from existing code.
2970 * dbxread.c (really_free_pendings): Don't free pending_blocks;
2971 they are in an obstack.
2972 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
2974 (define_symbol): Add symbol type parameter; change callers;
2975 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
2976 it to influence the symbol class on the i960.
2977 (define_symbol): Swap LOC_CONST's into target byte order.
2979 * exec.c (exec_close): New function.
2980 (exec_file_command): Call it.
2982 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
2983 Fix byte order of frame pointer.
2984 (read_var_value): Result of 0 if var's value can't be found,
2985 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
2986 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
2987 (locate_var_value): Use read_var_value and use its lazy address
2988 as the location of the var's value. Lint.
2990 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
2993 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
2994 obsolete Intel versions in favor of vxgdb versions.
2995 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
2996 code dealing with byte order of values, which Intel did in host byte
2997 order rather than gdb-4's target byte order.
2998 (i960_frame_chain_valid): Move to nindy-tdep.c.
2999 (examine_prologue, skip_prologue, frame_find_saved_regs,
3000 frame_args_address, leafproc_return, saved_pc_after_call,
3001 pop_frame): Add vxgdb versions from Mark Fox.
3002 (examine_prologue, frame_struct_result_address): Add code
3003 to deal with the saved value of G13 (struct return address
3005 (frame_args_address): Modify Mark's version to prefer the
3006 saved value over the current value in the topmost frame.
3007 Cache result in the frame info to avoid performance hair in
3009 (print_fault): Add gdb960 code for printing faults.
3010 (_initialize_i960): Actually call check_host.
3012 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
3013 add stub routines. FIXME, these currently just return zero!
3015 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
3016 (attach_command): Call target_attach, not target_open, now.
3018 * infrun.c (normal_stop): Make global, not static, for vx_attach.
3019 (child_attach): Rename from child_open.
3020 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
3021 don't confuse it with a zero step_resume_break_address.
3023 * inftarg.c (child_detach): Eliminate inferior_pid test.
3024 (child_files_info): Clean up message a bit.
3025 (child_ops): Use child_attach, not child_open, to attach.
3027 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
3028 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
3029 findvar.c to here, since it depends on the contents of the
3030 shadow_contents of breakpoints, but keep if #if 0 since it is
3033 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
3036 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
3037 (ptype_command, display_command): Eliminate have_inferior_p and
3038 have_core_file_p in favor of target_has_stack or
3039 target_has_execution.
3040 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
3041 code for actually finding the values of arguments, though we still
3042 keep track of the maximum stack offset for use in printing unnamed
3043 arguments. Handle missing FRAME_ARGS_ADDRESS.
3045 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
3046 (struct nindy_regs): Define registers passed to/from nindy.
3047 (nindy_fetch_registers, nindy_store-registers): Translate between
3048 nindy and GDB formats for the registers.
3049 (dcache_init): Statically allocate the cache, since it was being
3050 allocated by a malloc that was never freed anyway.
3051 (nindy_create_inferior): Error, not core dump, if no exec file.
3052 (nindy_before_main_loop): Use target_load, not target_add_file.
3054 * remote-vx.c (net_load): Specify large timeout for load
3055 requests. Allow user to break out with INTERRUPT.
3056 (net_break): Remove useless code, clean up. Change callers.
3057 (parse-args, skip_white_space, find_white_space): Clean up arg
3058 parsing to cope with quoted strings.
3059 (net_wait, net_quit): Never call error, just return status.
3060 (vx_read_register, vx_write_register): Cleanup status checking.
3061 #ifdef the code based on which CPU we are using (960 or 68k),
3062 FIXME, this should be completely general but it isn't yet.
3063 (vx_xfer_memory, vx_resume): Cleanup status checking.
3064 (vx_run_files_info): Improve message.
3065 (vx_load_command): Renamed from vx_add_file_command. Allow load
3067 (net_ptrace): Remove unused routine.
3068 (vx_wait): Adopt code from vxgdb960 to cope with broken
3069 connections to target machine and prompt to disconnect. Remove
3070 debug printouts. Map some EVENT_'s to SIGnals.
3071 (add_symbol_stub, vx_open): Print names of object files we found,
3072 and "ok" if we read their symbols OK. Clarify output in general.
3073 (vx_attach, vx_detach, vx_kill): Add these commands.
3074 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
3075 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
3076 "info files" output, and create_inferior, since we already have
3079 * stack.c (frame_info): Replace Frame_unknown with 0.
3080 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
3081 (return_command): Pop until the PC matches as well as the FP,
3082 so it works even if the FP is shared with another function,
3083 as in "frameless" or "leaf" procedures.
3085 * symfile.c (load_command): renamed from add_file_target_command.
3086 (add_syms_addr_command): renamed from add_file_addr_command.
3087 (add_syms_command): Stub to call target_add_syms.
3088 (_initialize_symfile): Change command names and descriptions,
3089 add-file => add-syms, and load from alias to its own command.
3091 * target.c (kill_or_be_killed, maybe_kill_then_attach,
3092 maybe_kill_then_create_inferior): Default for attempts to start
3093 a process, if one is already running, is to ask about killing
3094 it and retry if yes.
3095 (upstack_create_inferior): #if-0 it, strata obsolete it.
3096 (push_target, unpush_target, pop_target): to_close() a target
3097 before unstacking it.
3098 (target_info): Renamed from target_files_info.
3099 (_initialize_targets): Rename "i files" as "i target", accessible
3102 * target.h: Improve comments about the target_ vectored routines.
3104 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
3105 Convert commenting style to standard GNU style.
3106 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
3107 (SKIP_PROLOGUE): No longer a no-op.
3108 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
3109 (*_REGNUM): Sort register numbers.
3110 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
3111 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
3112 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
3113 are now 10 byte extendeds, not 8 byte doubles.
3114 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
3115 for nindy versus vxworks targets. FIXME, this should possibly go
3116 in the target vector.
3117 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
3118 frame_saved_regs and arg pointer with each frame.
3119 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
3120 (FRAME_ARGS_ADDRESS): Use cached result.
3121 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
3122 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
3123 (PRINT_RAMDON_SIGNAL): Call print_fault.
3124 (POP_FRAME): Now works.
3126 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
3127 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
3128 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
3129 (ADDITIONAL_OPTION_HANDLER): use target_load, not
3132 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
3133 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
3135 * valarith.c (value_subscripted_rvalue): Avoid handling
3136 floats and doubles specially; it gave alignment errors. Lint.
3138 * valops.c (value_of_variable, value_of_this): Error if unknown
3141 * valprint.c (print_floating): Bcopy rather than pointer-deref,
3142 to avoid alignment problems.
3143 (value_print): Handle unknown value address.
3144 (cplus_val_print): Two args are ignored; remove them. Change caller.
3145 (val_print): Use unpack_long rather than pointer-deref.
3148 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
3149 to avoid alignment problems.
3150 (value_being_returned): Error if return value unknown.
3151 (set_return_value): Add bogosity warning, FIXME. *
3153 * TODO: A woman's work is never done.
3155 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
3156 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
3157 Add ieee-float.o to OBS.
3158 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
3159 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
3160 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
3162 Changes to generalize the VxWorks RPC protocol slightly, to handle
3163 i960 as well as 68000.
3165 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
3166 * vx-share/reg.h: Produce i960 regs #ifdef I80960
3167 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
3168 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
3169 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
3170 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
3171 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
3172 so they will move in target byte order rather than network
3173 byte order (happens to be the same).
3175 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
3177 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
3179 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
3182 Add contribution lines to various files, showing where they
3185 * breakpoint.c (break_insn, check_break_insn_size,
3186 read_memory_nobpt): Remove to mem-break.c.
3188 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
3191 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
3192 entry has bad register number. This change is not
3193 tested in this release, FIXME.
3195 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
3198 * value.h: Force value's contents field to be aligned to hold
3199 at least a double or a long long (if supported). This avoids
3200 doing bcopy's in and out of the contents field.
3202 (step_1): Avoid coredump under obscure circumstances when we
3205 * symtab.h (misc_info): Add field to misc function vector for
3206 any kind of cached information the target code desires. AMD
3207 29000 uses this to avoid repeating examine_function_prologue's.
3209 * coffread.c: Lint. Remove static symfile, read_section_header.
3210 core.c (have_core_file_p): Lint: remove.
3211 expprint.c (print_subexp): Lint.
3212 infptrace.c, valops.c, valprint.c: lint.
3214 Roll in changes from vxgdb-5.0.1:
3216 * symtab.h: Comment byte order of each address class. Add
3217 LOC_LOCAL_ARG for frame-relative args (960).
3218 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
3219 symtab.c, symmisc.c: ditto.
3221 * infrun.c (init_wait_for_inferior): Clear stop_signal.
3223 * remote.c (remote_resume): Error if resume with a signal.
3225 * symfile.c (prim_record_misc_function): Clear misc_info.
3226 (fill_in_vptr_fieldno): Check stub type of arg.
3228 * valops.c (value_cast): Avoid looking up names of types whose
3229 name we don't know, to prevent coredump. Sun CC produces typedef
3230 rtx and the name of *rtx is zero...
3232 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3234 Roll in changes from final AMD 29000 port (Tiemann).
3236 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
3237 for ../include/a.out.encap.h. This might not work now that BFD
3238 is separately compiled. Instead, BFD support for encap will have
3239 to translate machine type 29k into the right COFF_MAGIC.
3241 * infcmd.c: Remove references to inferior_pid that aren't used
3242 in actual ptrace calls; use target_has_execution, etc.
3243 (have_inferior_p): Remove function.
3244 (program_info): Print target info rather than "process number";
3245 avoid gratuitous messages unless from_tty.
3246 (run_stack_dummy, finish_command): Set proceed_to_finish.
3247 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
3248 main.c: Lint. Lose have_inferior_p().
3249 inferior.h (have_inferior_p): Remove, lint.
3250 (proceed_to_finish): Add flag to ask that all regs be saved
3251 by normal_stop, for the few commands that need it, speeding up
3252 serial I/O. Add comments to stop_registers.
3254 * remote-eb.c: Remove newline from breakpoint message we grep
3255 for. Never time out when running the user program.
3259 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3261 Roll in changes from vxgdb-5.0.1:
3263 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
3264 symbol in its raw form, we are processing an unlinked ".o" file.
3265 See if the target environment has assigned it an address, using
3266 target_lookup_symbol (VxWorks does), and enter it into the symtab
3269 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
3270 68k versions for a simpler version that assumes zero FP at bottom.
3271 Fixes bug of truncated stack reports.
3273 * target.h (target_lookup_symbol): Define this routine's args
3274 and result, finally.
3276 * target.c (nosymbol): Default routine for target_lookup_symbol.
3277 (target_default): Default lookup_symbol and call_function too.
3278 (files_info): Only print has_all_memory warning if a non-dummy
3281 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
3282 vx_convert_from_virtual): If target does not have floating point,
3283 zero register "values", and avoid doing cross-net conversions.
3284 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
3285 (vx_open): Rearrange code that attaches to target and reads
3286 symbols for all loaded modules, to work if some of the modules
3287 are not accessible. Add symbol_stub() and add_symbol_stub()
3288 as callbacks from catch_errors(). Allow connect attempt to be
3289 interrupted painlessly with ^C (FIXME, there are still some bugs
3290 if the interrupt happens during symbol reading.). Print
3291 final message with puts_filtered, since symbol messages are
3296 * main.c (catch_errors): Only print errstring if non-null.
3297 (command_loop): Avoid an ioctl per command to test ISATTY.
3299 * remote-vx.c (net_load): make static; avoid sophomoric msg.
3300 (vx_xfer_memory): Return correct result!
3301 (vx_files_info): Indicate whether target has float or not.
3302 (vx_lookup_symbol): Complain, not error, if target gone.
3303 (vx_open): Print "Connected" msg before disabling immediate-quit.
3304 [FIXME: lookup_symbol and vx_open changes need testing.]
3306 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
3307 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
3308 contributor lines and update copyrights to 1991.
3310 Changes from an attempted H-PUX host port:
3312 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
3313 defines PT_ATTACH and PT_DETACH but not PT_KILL.
3314 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
3315 * remote-vx.c: include <sys/time.h> for HPUX.
3316 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
3317 "core_file_command" routine to BFD regime. May not work yet.
3319 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
3321 * xgdb.c: Replace X10 version with some VJ version.
3322 (FIXME: Its copyright assignment is not on record.)
3323 * xgdb.c: Update include files to X11R4 (Xaw crud).
3324 (xgdb_display_source, create_text_widget): fix call to
3325 get_filename_and_charpos. Rewack source window stuff for X11R4
3326 (gleaned from include files, and "nm's" of binary libraries, since
3327 I had no doc available).
3328 (append_selection, append_selection_word): Disable with FIXME
3329 since R4 changed interface here.
3330 (create_buttons): Add back the old set of buttons.
3331 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
3333 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
3334 Roll VERSION to 3.94 (not yet final though).
3336 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3338 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
3339 obstack_int_grow, obstack_int_grow_fast): Eliminate
3340 cast on left of assignment, which gives MIPS cc fits and is
3343 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
3344 F_ALIAS. Use printf, not fprintf, when not passing a file
3346 (compare_opcodes): Check that identical instructions have
3347 identical opcodes, complain otherwise.
3349 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
3350 was reported by Roland McGrath.
3351 (unimp): Only match if exactly zero instruction. (Roland)
3352 (branches and traps): Generate all variations of these
3353 instructions with macros, based on a single call that defines
3354 each condition name and its binary representation.
3355 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
3357 * valprint.c (val_print_fields): Take, and use, format parameter.
3358 This means that "p/x struct" again prints the elements in the
3359 desired format. Changed callers.
3361 * stack.c (frame_info): Use filtered output, and indicate wrap
3362 points. Remove kludgy formatting designed to avoid line wrap.
3364 * utils.c (wrap_here): If the line is already full (because
3365 we had printed a long indent or long wrapped string), do an
3366 immediate newline-and-indent.
3368 * m68k-pinsn.c (print_insn_arg): Bugfix from
3369 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
3370 instruction is incorrectly disassembled as bkpt #8.
3372 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
3373 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
3374 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
3375 and then will dump core (sometimes). I traced it back to an
3376 uninitialized symfile_name in psymtab_to_symtab.
3377 (const_vol_complaint): Add quotes to message.
3378 (define_symbol): Only believe line number if gcc_compiled.
3379 Avoid allocating symbol if we will not return it.
3381 Add target strata support so that newly established targets go
3382 into their right place in the target stack (e.g. a new exec file
3383 doesn't wipe out the ability to access the running process).
3385 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
3386 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
3387 and initialize it properly in all the targets.
3389 * target.h: Document strata. Change return type of push_target.
3391 * target.c (nomemory): new function for dummy memory access.
3392 (tcomplain): Rename complain, now also used in symfile.c.
3393 (push_target): Push targets within strata. New return value shows
3394 whether new target is on top of stack or not. Always keep dummy
3396 (target_files_info): Ignore dummy target.
3398 * core.c (core_open): Warn user, and skip accessing file, if the
3399 core target is not the topmost target in the stack.
3400 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
3403 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
3404 target_ops, it doesn't belong there since we have no regs there.
3405 Change name of target from machine => memory to clarify.
3407 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
3409 * Freeze version 3.93 for release.
3411 * Makefile.dist: Handle vx-share and nindy-share subdirs
3412 properly when building gdb.tar.Z.
3414 * symtab.c: lint; add no_symtab_msg to consolidate the messages
3415 printed in various places, so I could change just one copy.
3417 * dbxread.c, coffread.c: Change references to bfd->iostream
3418 to cast to FILE *, now that BFD avoids needing types defined
3419 in other header files.
3421 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3423 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
3424 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
3425 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
3426 (actually gcc -Wall).
3428 * dbxread.c: Remove first_global_sym, last_global_sym, since
3429 they are never referenced.
3431 * defs.h (baud_rate): Declare.
3432 main.c: Define it, and add the -b option to set it.
3434 * gdb-int.texinfo: Add text on how to define a new host or target
3435 architecture, prompted by Per Bothner's questions about MIPS
3438 * gdb.texinfo: Document "complaints". Change doc of -q since
3439 gdb no longer prints the copyright and blurb if you specify a file
3440 name to be debugged (just like Emacs). Add doc for Nindy-specific
3441 command line flags for specifying target serial port and such.
3442 Update copyright to 1991.
3444 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
3445 has taken over for us the job of ripping up executable files. The
3446 crud caused Per Bothner's port to not compile.
3448 * infrun.c (normal_stop): Avoid printing "Program exited
3449 normally" if we are in batch mode. This allows a GDB which
3450 executes a program on a target system, to behave like a Unix
3451 command (input from stdin, output to stdout, no extraneous
3454 * main.c (main): Allow additional machine-dependent command line
3455 options to be specified with the ADDITIONAL_OPTIONS,
3456 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
3457 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
3458 processing to occur just before the main loop with
3459 BEFORE_MAIN_LOOP_HOOK.
3460 (main): If a "core file" argument is specified, and it is not a
3461 core file, try it as a process ID to attach.
3462 (symbol_completion_function): Attempt to cope with
3463 "show screen-" TAB, not very successfully. This needs more work,
3465 (batch_file): New function, returns whether we are reading
3466 commands from an interactive tty on stdin, or from somewhere else.
3467 Called by normal_stop since it doesn't get from_tty passed down
3468 to it like many commands do.
3470 * remote-nindy.c: Handle command line options for nindy
3472 (nindy_before_main_loop): Prompt user for tty name if they
3473 don't specify it before getting to the interactive command loop.
3475 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
3476 and -r command line options. Also add hook before main loop
3477 to make it easy to specify a tty.
3479 * TODO: More things to do, one done.
3481 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
3483 * dbxread.c: Make complaint() calls pass pointer, not struct.
3484 Add complaints about badly formatted C++ type information
3485 (const/volatile indicator, and parse errors resulting in
3486 error_type). Fix C++ virtual member fn comment.
3487 (read_struct_type): Avoid bumping pointer if we got a parse
3488 error; this prevents our walking beyond the end of a string.
3489 Terminate loop on null char as well as semicolon.
3490 (process_one_symbol): Fix the LBRAC fix so that it uses the
3491 last previous SLINE, FUN, or SO record's PC address. C++ debug
3492 symbols did not have SLINE records in a useful order compared
3493 to the LBRAC records.
3494 (define_symbol): Handle "catch" records.
3496 * symtab.c (check_stub_type): Added new complain
3497 `stub_noname_complain' and added a consistency check to
3498 keep the debugger from crashing when finishing from an
3499 exception frame. A real fix will be needed later.
3501 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
3503 * infcmd.c (attach_command): Make global.
3505 * Makefile.dist (REMOTE_OBS): Make these compile by default,
3506 but make them easy to comment out. Perhaps later they should
3507 be enabled by what CPU you configure for? FIXME.
3508 (VERSION): Roll to 3.93.
3509 (pinsn.o): Remove rule for obsolete file.
3510 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
3512 Run down a problem that manifested by printing the wrong function
3513 name in stack traces of read_ofile_symtab. Turned out that the
3514 problem was the SunOS 4.1.1 (and previous) C compiler outputs
3515 the LBRAC symbol with an address in the *data* segment, which
3516 blew our binary search through the blocks.
3518 * dbxread.c: Use the complain() facility consistently to bitch
3519 about problems in the symbol file we are reading.
3520 (finish_block): Add code to check the nesting of the blocks;
3521 complain and Procrust them to fit if wrong.
3522 (make_blockvector): Check the order of the blocks, complain
3523 [but don't cope] if wrong.
3524 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
3525 symbols to be sure their PC value is greater than the last SLINE
3526 (line number) symbol we've seen, complaining and adopting the
3527 SLINE PC value if wrong.
3529 * symfile.h (struct complaint, complaint_root, complain,
3530 clear_complaints): Add.
3531 * symfile.c (complain, complaint_root, clear_complaints): Add
3532 facility to deal with non-fatal complaints and to regularize their
3534 (symbol_file_add): Clear complaint counters to allow new complaints.
3535 (initialize_symfile): Add 'set complaints' and 'show complaints'.
3537 * dbxread.c (dbx_symfile_read): Remember the address and size
3538 of the string table for the main symbol file, so we won't read it
3540 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
3541 to avoid reading the string table yet again. Lint.
3542 (throughout): Improve filtered output, including word wrap.
3543 (read_range_type): Improve Bothner's fix to handle other types too.
3545 * utils.c: Improve line wrap implementation. Handle unlimited
3546 width by making chars_per_line unsigned.
3547 (puts_filtered): New, easy, function.
3549 * defs.h (puts_filtered): add.
3551 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
3552 call the identical sort_symtab_syms() in symfile.c instead.
3554 * expread.y: Suggest the `file' command rather than `symbol-file'.
3556 * command.h (enum var_types): Add zinteger for seroable
3558 * command.c (do_setshow_command): Handle var_zinteger. Restructure
3559 nested if's into a switch.
3561 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
3562 we did not stop because of a breakpoint (it must have been for
3563 some other reason, like a "stepi"), so don't print anything.
3565 * symtab.c: Include <sys/types.h> all the time. Now that BFD
3566 doesn't include <sys/types.h>, old SunOS's require it for
3569 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
3571 A test port of gdb-3.92.6 to the Sony NEWS.
3574 Don't normally link in remote- or vx stuff.
3575 Some of it doesn't compile, and it wastes space for 99% of the users.
3576 Remove reference to no-longer-used HAVE_VPRINTF.
3577 Fixed BFD_DEP typo to BFD_DIR.
3579 Fix cast in arg to bfd_h_getlong.
3580 Make char *prefix be const.
3581 Fix how certain range types are mapped into builtin unsigned int types.
3583 Remove 2 #includes. They cause errors (on Sony, at least),
3584 and aren't needed (they wern't in earlier versions).
3586 print_address_symbolic should never demangle labels
3587 (since it prints *assembler-level* labels).
3589 [This was superseded by the change to printcmd below.]
3592 Add some "volatile" return types to avoid warnings.
3593 If MISSING_VPRINTF add vprintf function and not just macro
3594 (since vprintf is used in printcmd.c).
3596 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
3597 (The latter isn't grokked by some PCC-based compilers.)
3599 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
3601 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
3602 * nindy-share/coffstrip.c
3603 Added some forward declarations (otherwise, gcc complains
3604 about implicit extern redefined as static).
3606 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
3608 Changes inspired by Per Bothner:
3609 * printcmd.c (print_address_symbolic): Take additional parameter
3610 specifying whether to demangle.
3611 (print_address): Pass in asm_demangle to control demangling.
3612 (print_address_demangle): New fn, takes explicit arg to control
3614 * utils.c: Add new vars demangle and asm_demangle, and let them
3616 (fputs_demangled): If !demangle, just print the argument.
3617 (fprint_symbol): If !demangle, just print raw symbol.
3618 * valprint.c (val_print): Call print_address_demangle rather than
3619 print_address, to cause demangling to depend on the global
3620 rather than assembler-level demangling setting.
3621 * WHATS.NEW, gdb.texinfo: Document.
3623 * main.c (show_command): Show all settings if no arg.
3624 (initialize_main): Make "info set" the same as naked "show".
3625 * command.c (cmd_show_list): Handle prefix commands in the
3626 list, and print the name of the setting as well as its English
3627 description and value.
3629 Allow gdb functions to specify where a line should wrap if it
3630 exceeds the size of a terminal line. Use it to make the output
3632 * utils.c (set_screen_width_command): New fn, mallocs a buffer
3633 of the right size when screen width changes.
3634 (set_screensize_command, screensize_info): Remove #if 0'd fns.
3635 (wrap_here): New fn, indicates a point in the output where we
3636 should wrap the line rather than just letting it overflow at a
3638 (fputs_filtered): Implement wrapping.
3639 (n_spaces): New fn, returns a pointer to N spaces.
3640 (print_spaces_filtered): Use n_spaces.
3641 * defs.h (n_spaces): Declare.
3642 * stack.c (print_frame_info): Wrap with 4-space indent after
3643 fn name and before filename and line number.
3644 * printcmd.c (print_frame_args): Wrap with 4-space indent
3645 before each argument name is printed.
3646 * valprint.c (value_print): Wrap with no indentation before
3648 (val_print_fields): Wrap with indentation relative to nesting
3649 level before each field name.
3650 (val_print): Wrap with nesting indentation before array elements.
3651 * command.c (do_setshow_command): Avoid extra newlines,
3652 wrap with 4-space indent around values printed, end with period.
3653 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
3655 * breakpoint.c (breakpoint_1): Implement addressprint for
3656 "info breakpoints" display. Change file name and line number
3657 format to " at file:nnn" rather than " (file line nnn)".
3658 * gdb.texinfo: Document.
3661 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3663 Frozen for gdb-3.92.6 release.
3665 README, WHATS.NEW: Update for 3.92.6 release.
3667 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
3668 coffread.o from configs since it is now built by default.
3669 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
3670 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
3671 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
3672 from configs since it is now built by default.
3674 Makefile.dist: Update for release 3.92.6. Handle files that
3675 have been moved to ../include, ../getopt, or ../bfd. Add
3676 saber.suppress and tests directory. Add config.status to
3677 the release (it will say "none").
3679 coredep.c: Minor formatting fixes.
3681 These changes were made in early December but only checked in now:
3682 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
3683 nindy-share/nindy.c: lint
3684 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
3685 register values coming back from the target; we store values
3686 in target byte order everywhere.
3688 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
3690 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
3692 * valprint.c (cplus_val_print, val_print_fields): New functions,
3693 which print C++ objects. They conspire to avoid printing a
3694 virtual base class more than once, following all the twists and
3695 turns of C++ virtual base rules.
3696 (val_print): Call the above rather than do it by hand.
3698 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
3699 symbol file, not for added files like shared libs. This really
3700 needs to be generalized to a timestamp per file.
3702 * core.c (cleanup_core): Avoid coredump if no core file.
3704 * config.gdb: Accept -host or -target in place of +host or
3707 * coffread.c (find_linenos): Avoid desupported BFD interface
3708 to line numbers. We still read them manually rather than using
3709 BFD's "generic" features.
3711 * gdbrc.tex, threecol.tex: Add GDB reference card and its
3713 Makefile.dist: Add refcard to OTHERS list for creating tar files.
3715 * Makefile.dist: Eliminate use of $< in explicit targets.
3717 * readline/Makefile: Use $< rather than $*.c, which does not
3718 include the VPATH in GNU Make.
3720 * tconfig/i960-bout, tconfig/i960-coff: These are identical
3721 copies of tconfig/i960, added for global configuration
3722 compatability. All i960 versions can read both coff and b.out.
3724 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
3725 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
3728 * TODO: Think of more things to do.
3730 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
3732 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
3733 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
3734 64-bit float conversion.
3736 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
3737 equivalent to sun?os4 so global config works.
3739 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
3741 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
3743 * main.c: Only declare linesize once; declare pagesize not at
3744 all, since it is never used.
3745 (main): Clear newly allocated line before it is used.
3747 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
3749 Further stabilization for the Intel 960.
3751 * Makefile.dist: Parameterize the location of the "include"
3752 and "bfd" directories, as well as "getopt". Add symfile.c.
3753 Link in both dbxread and coffread. Fix up "make depend" to
3754 rewack the locations of include, bfd, and getopt in its output.
3756 * README: Document moving include files, improve some of
3759 * coffread.c: Move common code out to symfile.c. Change
3760 symbol_file_command style interface to use new *_symfile_init
3761 and *_symfile_read interface under BFD. Use BFD internal
3762 info to locate line table, symbols, etc.
3764 * core.c (core_fetch_registers): Rename to get_core_registers
3765 to avoid confusion with fetch_core_registers.
3766 (register_addr): Move to coredep.c, which is already machine
3767 dependent. This leaves core.c pretty clean of dependencies.
3769 * coredep.c (register_addr): Accept this routine from core.c.
3771 * dbxread.c: Move common code (with coffread.c, etc) into new
3772 symfile.c. Each psymtab now contains a pointer to the
3773 format-dependent function that knows how to read it in. Make
3775 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
3776 (process_one_symbol): Add code to complain about a "compiler bug
3777 we muzzle here", if we actually see it.
3779 * eval.c (evaluate_subexp): Insert missing "break" statements
3780 in code that determines whether a variable is an lvalue in
3781 memory, register, or whatever. I detected this via a compiler
3782 bug in which it *almost* mashed out the whole switch statement.
3784 * gdb-int.texinfo: Add minor sections on configuring gdb for
3785 release, and about the README file.
3787 * infcmd.c (registers_info): Fix formatting somewhat. Still
3788 not as pretty as before, but it handles byte swapping.
3790 * remote-nindy.c: If data cache routines are interrupted while
3791 waiting for the remote end, be sure that any uninitialized cache
3792 blocks are on the free list, not on the valid list!
3794 * symfile.h: Flesh out this header file with all the various
3795 routines and variables that have been merged in from dbxread.c
3796 coffread.c, and symtab.c to symfile.c.
3798 * symfile.c: New file, containing code common to dbxread.c,
3799 coffread.c, and some code from symtab.c. All generic code for
3800 reading symbol files should be in here now.
3801 (unrecord_misc_function): Remove unused function.
3803 * symtab.h: Remove file-reading things to symfile.h.
3805 * symtab.c: Remove file-reading things to symfile.c.
3807 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
3808 to decode i960 fault types.
3810 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
3811 target.c: Change type of the "resume" function from int to void,
3812 since its result was never used.
3814 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
3816 * main.c: Replace "stupid" with "caution"; you now "set caution
3819 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
3821 * infcmd.c (do_registers_info): Call val_print to deal with the
3822 byte order of the registers being printed. FIXME, this makes
3823 the formatting of the output uglier.
3825 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
3826 defined, call it for signals the debugger doesn't itself use.
3827 The i960 uses this for more detailed fault information.
3829 * remote.c (remote_open): If arg is null, print help rather than
3832 * sparc-xdep.c (register_valid): Avoid declaring size, since
3833 various modules will think of various sizes depending on the
3834 architecture of their tm-file. FIXME, we need protection against
3835 actually entering one of those modules, which would clobber
3836 storage if not for the target architecture compiled into gdb.
3838 * stack.c (up_command, down_command): Always print the frame
3840 (up_silently_command, down_silently_command): New commands
3843 * i960-pinsn.c (reg), i960-tdep.c: Lint.
3845 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
3846 more parameters than it used to.
3848 * findvar.c (registers): Increase slop to 256 bytes, which should
3849 protect us against even most RISC machines with large register
3851 (locate_var_value): Move declaration inside related ifdef.
3853 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
3854 throughout, to avoid throwing away buffered input from the board.
3855 (nindy_wait): Supply_register takes addr_of_value, not value.
3856 (i960_print_fault): Renamed from i80960_fault.
3857 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
3858 (nindy_store_registers): Avoid regs_changed stuff, just stuff
3860 (nindy_create_inferior): Don't bother to write PC_REGNUM since
3861 we can set the PC in the call to proceed(). Unpush nindy_ops
3862 before pushing it on top, to avoid message to user. Eliminate
3863 commentary from Unix machines that just misleads here.
3864 (reset_command): Fix error message to suggest target command.
3866 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
3868 Release 3.92.5 as frozen.
3870 Stabilize the merged release...with help from lint, Saber C,
3873 Everywhere: Add include files needed to declare return types
3874 of functions called.
3876 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
3878 * breakpoint.h: Add undeclared breakpoint functions, and some
3879 functions for display handling since I couldn't think of a better
3882 * breakpoint.c (insert_breakpoints): Make code for disabling
3883 shared library bkpts more likely to work. It's used when we
3884 rerun a program and stop before the shared library has been
3886 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
3887 cast from pointer, so it squeezes through catch_errors.
3888 (bpstat_stop_status): Fix logic broken some time ago. We now
3889 always create a bpstat if the stop address matches a breakpoint,
3890 even if we don't stop there -- just like the old code used to do
3891 before I got my fingers into it (sigh).
3892 (breakpoint_1): Print "ignore count" after "stop only if"
3893 condition, since that's how it actually works.
3894 (mention): Handle watchpoints as well as breakpoints.
3895 (watch_command): use set_raw_breakpoint and mention to do most
3896 of the work (and initialize all the fields!). Only pass one
3897 arg to parse_c_expression, since that's all it takes.
3899 * command.c (not_just_help_class_command): Rename arg to args
3900 since we ignore "unused argument" warnings on vars named "args".
3901 inflow.c (child_terminal_info): ditto.
3902 infptrace.c (kill_inferior): ditto
3903 main.c (catch_errors, version_info, quit_command, pwd_command,
3904 source_command, dump_me_command, editing_info,
3905 set_history_size_command, set_history, show_history,
3907 stack.c (locals_info): ditto
3908 target.c (target_files_info): ditto
3909 valprint.c (set_input_radix, set_output_radix): ditto
3911 * core.c: Remove old variables for handling core and exec file
3912 sections (data_start, data_end, stack_start, stack_end,
3913 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
3914 text_end, exec_data_start, exec_data_end, text_offset,
3915 exec_data_offset, data_offset, stack_offset). They're
3916 superseded the more general build_section_table and
3918 (get_exec_file): Mention the `file' command.
3919 (read_memory_check): Rename to memory_error, and only call it
3920 in the case of an actual error.
3921 (read_memory, write_memory): call memory_error.
3922 (core_fetch_registers): Register section name is ".reg".
3924 coredep.c: Remove a bunch of crud now that all this file does
3925 is pull the registers out of a core file.
3926 (fetch_core_registers): Rewrite to actually work, I hope.
3928 dbxread.c: Use a.out.gnu.h, not system a.out, now.
3929 Replace index() with strchr(). Remove all the pre-BFD macro
3930 definitions for accessing the symbol file.
3931 (struct dbx_symfile_info): Encapsulate the information that
3932 dbx_symfile_init needs to pass to dbx_symfile_read in this
3935 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
3936 dbx_symfile_discard): Rearrange symbol file reading to divide
3937 the format-specific part from the format-independent part,
3938 leaving the format-independent part such as file name expansion
3939 and opening in symtab.c. This replaces
3940 partial_symbol_file_open and partial_symbol_file_read.
3941 Symbol_file_read, add_file, add_file_target_command,
3942 add_file_addr_command move to symtab.c. Pass an explicit
3943 "mainline" flag for when reading the main symbol table, rather
3944 than relying on the offset address to be zero or nonzero.
3946 (dbx_symfile_read): Don't allow void *'s to be printed as
3948 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
3949 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
3950 macro" debug version really work.
3951 (read_dbx_symtab): Remove unref'd parameter inclink.
3952 Avoid swapping N_SLINE symbols, for speed.
3953 Merge N_TEXT!N_EXT case with the other external symbol
3954 definitions' case. Add comments.
3955 (start_psymtab): Allocate the symfile name in the psymtab on
3956 the psymbol_obstack, rather than using the caller's storage.
3957 (end_psymtab): Only allocate a dependencies list if there are
3959 (psymtab_to_symtab_2): Use BFD when reopening file to read
3960 its symbols for real.
3961 (read_struct_type): Add FIXME comments where it needs work
3963 (read_huge_number): Add FIXME about overflows.
3964 (read_range_type): Add FIXME about comparing a long to 1<<32.
3966 * coffread.c: Minor changes to move things closer to the new
3967 regime with symtab.c and dbxread.c Major work is still needed
3970 * exec.c (exec_file_command): Remove old variables (see core.c
3972 (xfer_memory): If memory transfer is right at the end of a
3973 section, don't lose.
3975 * findvar.c (get_saved_register): If value is in a real
3976 register, LVAL is lval_register, not lval_memory.
3978 frame.h: Declare print_sel_frame and record_selected_frame.
3980 gdb-int.texinfo: New file, for GDB internals documentation.
3981 Very simple, unformatted doc of cleanups is there for now.
3983 gdbcore.h: Remove obsolete variables that described a.out
3984 section addresses and offsets. (See core.c above.)
3985 Declare fetch_core_registers and registers_fetched.
3987 getopt.c: Declare char *alloca(); even on SPARC.
3989 infcmd.c (run_command): Call target_kill rather than
3991 (step_command, next_command, stepi_command, nexti_command):
3992 Declare from_tty parameter even though we don't use it.
3993 (run_stack_dummy): argument BUFFER is a char array, not
3994 a pointer to REGISTER_TYPE.
3995 (finish_command): using_struct_return needed a value *,
3996 not a struct symbol *.
3998 * infptrace.c (child_xfer_memory): To avoid dependency on
3999 where sections are in memory, try PT_WRITE_D and if that fails,
4000 try PT_WRITE_I. Most Unixes don't care which you use.
4002 * infrun.c (step_resume_break_shadow): Change to array to
4003 match other breakpoint shadow storage.
4004 (clear_proceed_status): Pass address of bpstat to
4005 bpstat_clear, not the bpstat itself.
4006 (child_create_inferior): FIXME comment about if the child
4008 (start_inferior): Remove old function.
4009 (child_open): Use target_kill rather than kill_inferior.
4010 (wait_for_inferior): Ditto.
4011 (insert_step_breakpoint, remote_step_breakpoint): Use
4012 new step_resume_break_shadow.
4014 * inftarg.c (child_wait): If all child processes die,
4015 pretend that the one being waited for exited with signal 42.
4017 * main.c (command_line_input): When scanning for comments,
4018 don't coredump on unclosed quotes.
4019 (quit_command): Use target_kill rther than kill_inferior.
4020 (_initialize_main): Rename class_user from "user" to
4023 * printcmd.c (print_command_1): Initialize "fmt" if no format
4024 is specified by the user.
4025 (print_frame_args): Only add to args_printed if we are
4026 actually fetching args from the stack (avoiding undefined
4028 (_initialize_printcmd): Remove bogus \{ from string.
4030 * remote-eb.c (eb_open): Avoid coredump on no argument.
4032 * remote-nindy.c: Bring out of Intel environment into new
4033 target environment. Remove all conditional compilation on
4034 I80960. Massive hacking throughout.
4035 (nindy_xfer_inferior_memory): New routine stolen from
4037 (nindy_create_inferior): New routine pieced together, probably
4038 not quite working yet.
4039 (nindy_ops): New target_ops struct for nindy.
4041 * remote-vx.c: Use write_memory rather than target_write_memory
4042 to get error checking.
4043 (vx_add_file_command, vx_open): Use symbol_file_add rather than
4045 (vx_create_inferior): Use target_terminal_ours...
4047 * signame.c (_initialize_signame): Always initialize, since
4048 we need the table for things other than psignal.
4050 * solib.c (solib_add): Use symbol_file_add, not add_file.
4051 (solib_address): Return boolean result rather than struct
4052 pointer which nobody else knows the type of.
4054 * sparc-tdep.c, valops.c: Use write_memory rather than
4055 target_write_memory, to get error checking.
4057 * stack.c (locals_info, catch_info, args_info,
4058 get_selected_block, frame_command, up_command): Use
4059 target_has_stack, rather than have_inferior_p or
4062 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
4064 * symfile.h: New file, defining the interface between the
4065 generic and object-file-specific symbol reading code.
4067 * symtab.c: Move generic symbol-reading interface to symtab.c,
4068 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
4069 table to map BFD targets to symbol-reading modules in GDB.
4070 Change index to strchr.
4071 (lookup_struct_elt_type): Use error() rather than hand-made
4072 simulations thereof.
4073 (lookup_partial_symbol): Speedup slightly when length == 0.
4074 (symbol_file_add): New function.
4075 (symbol_file_command): Call it.
4076 (symfile_open, symfile_init): New function.
4077 (add_file_target_command, add_file_addr_command): moved from
4080 * target.c (target_command): use target_kill.
4082 * target.h (target_files_info): Don't declare, never called
4085 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
4086 files to determine stack end address.
4088 * valarith.c (value_x_binop, value_x_unop): Change error message
4089 to be more useful. Pass proper argument to value_struct_elt.
4091 * valops.c (value_assign): FIXME comment that long long
4092 bitfields will break here.
4094 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
4095 Update `make saber_gdb' to work better.
4097 * TODO: A woman's work is never done.
4099 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
4100 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
4101 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
4102 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
4103 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
4104 valops.c, valprint.c, exec.c: Lint.
4107 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
4109 Continuing Intel 960 port merge of GDB.
4111 * Makefile.dist: Merge i960 "nindy-share" files. Rename
4112 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
4113 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
4114 Wack over "make depend" so it handles files in subdirectories
4115 vx-share, nindy-share, bfd, and in the current directory.
4117 * blockframe.c (get_prev_frame_info): Remove fatal error
4118 if stack not defined.
4120 * core.c (core_open, core_detach): New functions that handle
4121 the old "core-file" command as "target core" and "detach" instead.
4122 (core_file_command): Call them.
4123 (core_xfer_memory): Use common routine xfer_memory.
4125 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
4126 dbxread now uses bfd for everything but symbol reading itself.
4127 BFD internals are used to drag out the relevant file offsets.
4128 (partial_symbol_file_open): Change args all around for BFD.
4130 * symtab.c: Rename "value" to "val" everywhere, so we can
4132 (symbol_file_command): New command, moved from dbxread.c
4133 and coffread.c. It uses BFD to read the file, then vectors
4134 based on its type, to dbx or coff symbol readers.
4135 * symtab.h: Extern a few vars for symbol_file_command.
4137 * target.h: Breakpoint takes a char * save area, not a char **.
4139 * valprint.c (val_print): When unpacking bitfields, offset
4140 the address in gdb of the value, if it is declared with a shorter
4141 type. Remove the last "runtime kludge test" of host byte order.
4143 * utils.c: Remove old my_bfd_read routine.
4145 * stack.c (frame_info): Use target_has_stack. Print program counter
4146 register's actual name rather than "pc", since it's called the
4147 "ip" (instruction pointer) on the i960 (sigh).
4149 * target.c (target_command): Add command for selecting a target
4150 type and calling its open routine. This is used for initiating
4151 communication with a particular target, in a generic way.
4153 * tm-i960.h: Update for modern gdb. Remove semicolons from
4154 various macros. Handle reading struct return convention, and
4155 error-out attempts to return structs with the "return" command.
4156 Be sure gdb doesn't think we know how to call functions in the
4159 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
4160 to i960_xxx in lower case.
4161 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
4162 not being defined yet.
4164 * remote.c (remote_open): Call start_remote to initialize
4165 wait_for_inferior during open.
4166 (remote_xfer_inferior_memory): Return length written rather
4169 * remote-vx.c (target_command -> vx_open): Use new generic
4171 * remote-eb.c, inftarg.c, exec.c: ditto.
4173 * infrun.c: Fix comments.
4174 (attach_program -> child_open): Use new generic target command.
4175 (wait_for_inferior): Clear saved register values before target_wait,
4176 so target_wait can set some of them if convenient.
4178 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
4179 Return success indicator, not void.
4180 (child_xfer_memory): Avoid fetching initial word if we'll
4181 overwrite it anyway.
4183 * infcmd.c (attach_command): Use new generic target open routine.
4184 (_initialize_infcmd): Update doc on attach and detach commands.
4185 (do_registers_info): Merge in a byte-order problem as a FIXME
4188 * findvar.c (find_saved_register): Avoid problem in current frame.
4189 (read_relative_register): Ditto.
4190 (write_register): Convert byte order on the way out.
4192 * exec.c (file_command): Add.
4193 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
4194 (xfer_memory): Common function between core_xfer_memory and
4196 (exec_xfer_memory): Use it.
4198 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
4200 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
4201 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
4202 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
4204 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
4206 Merge Intel 960 port of gdb, continuing...
4208 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
4209 symbol_file_command): Pass from_tty arg to hush 'em up.
4211 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
4212 Add magic numbers for 960 COFF format.
4214 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
4216 Merge Intel 960 port of gdb, from Intel "1.2" release.
4218 CHANGE_LOG entries from their port, which was based on
4221 Thu Sep 6 11:02:22 PDT 1990
4222 Remove temp file if download is interrupted.
4224 Wed Aug 1 09:08:33 PDT 1990
4225 Now uses binary protocol to talk to NINDY.

4227 Times out after 5 seconds when trying to talk to NINDY.
4229 Tue May 29 12:54:49 PDT 1990
4230 Added variable baud rate (-b switch).
4231 Source code reorganization.
4233 Thu Apr 26 11:09:55 PDT 1990
4234 More cleanup of batch mode; specifically, execute "-s", "-e", and
4235 "-se" switches as soon as they are encountered on the invocation line.
4237 Fri Apr 20 13:47:15 PDT 1990
4240 Thu Apr 19 09:54:28 PDT 1990
4241 Add 'reset' command.
4243 Wed Apr 18 09:48:07 PDT 1990
4244 After opening remote tty, wait for 1 second to go by without input
4245 from it before trying to talk to NINDY (fixes problems with the
4246 Heurikon HK80/V960E).
4248 Mon Apr 4 16:33:05 PDT 1990
4249 Some output was not being suppressed in 'batch' mode.
4251 Thu Mar 22 15:31:11 PST 1990
4252 Ask user if old symbol table should be deleted when new file is
4255 Allow user to run a program downloaded before gdb960 was brought up.
4257 Correct "exec-file" help message for i80960 context.
4259 Correct bug in calculating user space address: could occasionally
4260 corrupt user program.
4262 Make sure to zero low-order bits in rip's because of bug in 960CA
4263 A-step part: could cause operation faults when "next"ing across
4266 Correct bug that made it impossible to get source line numbers for
4267 code loaded at addresses higher than 0x7fffffff.
4269 Wed Jan 10 12:43:22 PST 1990
4270 Open remote tty for exclusive use.
4272 Fri Jan 5 12:14:42 PST 1990
4273 Correct disassembly (CA manual was right after all):
4274 opcode for sysctl is 0x659
4276 Mon Oct 23 12:03:04 PDT 1989
4277 Use G960BASE and G960BIN environment variables to find 'sx' utility.
4279 Mon Oct 16 14:15:09 PDT 1989
4280 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
4282 Mon Oct 2 15:56:31 PDT 1989
4284 Added 960CA disassembly support.
4286 To simplify maintenance:
4287 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
4289 - eliminated opcode.h: incorporates tables into i960-pinsn.c
4290 - moved 960-specific routines from i960-pinsn.c to i960-md.c
4291 - made disassembly interface identical to that in gdmp960.
4295 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
4297 * target.h: Allow targets to stack. Add target_has_memory,
4298 _registers, etc. Restructure memory access and "info files"
4299 to walk the target stack.
4300 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
4301 target.c: Change tables to match target.h.

4307 * remote-vx.c: New memory regime, new info files. Now use
4308 separate targets for VxWorks attachment to machine, and
4309 actually running a process under VxWorks, since one has
4310 stack & execution & regs and the other doesn't.
4311 * remote.c: New memory regime, new info files.
4312 * sparc-xdep.c (fetch_core-registers): New memory regime.
4313 * target.c: New routines and support for stacked targets,

4356 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
4358 Massive changes to wall off the remote-debugging interface
4359 behind a function vector. The port to handle VxWorks targets
4360 is also part of this.
4362 All files: Replace references to renamed functions,
4363 remove references to remote_debugging, remove references to
4364 have_include_file, have_core_file in favor of target_has_stack,
4365 target_has_memory, etc.
4367 * Modularize the breakpoint interface.
4368 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
4369 a breakpoint instruction.
4370 breakpoint.c: struct breakpoint's shadow_contents now sized as
4372 (insert_breakpoints): Vector to target to install breakpoints.
4373 (remove_breakpoints): Vector to target here too.
4374 Remove REMOTE_SA_SPARC kludges and other remote_debugging.

4376 the single-step breakpoints.
4377 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
4378 New file, contains routines to insert and remove breakpoints by
4379 reading out the old contents and later replacing them. This is
4380 how ptrace breakpoints work, and many remote systems as well.
4382 * tm-vxworks68.h: New config file, overrides a few things for
4383 Wind River's preferences.
4385 * target.h: New file, for transfer vector used to talk to the
4386 inferior (child, attached, core, exec, remote, etc). All accesses
4387 to the thing being debugged should come through these vectors.
4388 target.c: New file, routines to handle transfer vector.
4389 (various files): Add transfer vectors XXX_ops for the various
4390 targets and pseudo-targets (core files, etc) we support.
4392 * breakpoint.c (bpstat_stop_status): Further explorations of
4393 watchpoints and why things don't work all the time.
4394 (bpstat_alloc): New fn to allocate a bpstat and chain it.
4396 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
4397 the local gdbinit if it doesn't already have it.

4400 Allow core debugging without exec file.
4402 * dbxread.c (free_and_init_header_files): Merge two fns.
4403 (end_symtab): Free named symbol table when a new version comes in.
4404 (read_dbx_symtab): Relocate all kinds of symbols with base
4405 address. First step toward handling different text, data, bss
4407 (add_file_addr_command): Renamed add_file_command.
4408 (add_file_command): Vector to remote handler.
4409 Add "load" as an alias for "add-file" command.
4411 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
4412 non-returning functions.
4414 * exec.c: Add exec_ops, and push it as a target when an exec
4417 * infcmd.c (run_command): Pass executable file name and arg list
4418 separately when starting an inferior. Permit "run" when no exec
4419 file is specified, for VxWorks.
4420 (detach_command): Move to child_detach in inftarg.c.
4422 * inftarg.c: New file. Unix-child-specific routines, and the
4423 child_ops structure.
4425 * inferior.h (registers): Export "registers" as the way for
4426 target dependent register handlers to find gdb's local copy of
4427 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
4428 since it is now used by places that want wait_for_inferior to
4429 handle the grunge but want to see every trap from the inferior.
4431 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
4432 Eliminate remote_debugging hooks in terminal handling.
4434 * infrun.c: Replace start_inferior with child_create_inferior.
4435 Move all the hair of Unix shells and ptrace idiosyncracies into
4436 child_create_inferior, so remote handlers don't have to deal.
4437 Remove running_in_shell. Rename stop_after_attach to
4438 stop_soon_quietly, and use it in a few other places where we want
4439 to just call wait_for_inferior and get control back on the first
4440 trap. trap_expected now never takes a value > 1.
4441 (init_wait_for_inferior): Initialize static vars when a new
4444 main.c (gdbinit): Add new hook for .gdbinit file name, let
4445 it be overridden by config files as GDBINIT_FILENAME.
4446 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
4447 Both of these are used for VxWorks gdb.
4449 mcheck.c: rename include file "gmalloc.c" to avoid problems
4450 with system include file "malloc.c".
4452 param-no-tm.h: New include file, same as param.h but does not
4453 include the default "tm.h" file. This is used in files where
4454 the target is known, e.g. remote-eb.c or sparc-xdep.c.
4456 param.h: Now just a shell that includes tm.h and param-no-tm.h.
4458 remote-vx.c: New file, VxWorks remote debugging support. Uses
4459 RPC routines that are shared with the target system, in directory
4462 remote.c: Vectorize remote interface.
4464 source.c: Globalize source_path, and make an alias "l" for "list"
4465 since we now have the "load" command.
4467 sparc-xdep.c: Use new param-no-tm.h.
4469 symmisc.c (free_named_symtab): Add new function from Wind River.
4470 However, ifdef it out for now while we think about what it should
4473 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
4475 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
4476 non-Unix-children handle this with their own code in the target
4479 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
4480 source and target lists. Add vx-share to default list of include
4481 directories. Add new files to src and target lists: mem-break,
4482 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
4483 ${srcdir} versions of munch and createtags are used.
4485 * valops.c (find_function_addr): Split out of call_function.
4486 (call_function_by_hand): Rename call_function; this function
4487 calls functions in the target by laboriously patching the target
4488 word-by-word with the right stack, args, regs, etc.
4491 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
4493 Handle AMD 29000 a bit better.
4495 * remote-eb.c (readchar): Mask received char log to make it readable.
4496 (remote_start): Pass arguments down to executing program.
4497 Make startaddr unsigned.
4498 infrun.c (start_inferior): Accept args, pass them to
4500 infcmd.c (run_command): Pass args down to start_inferior.
4502 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
4503 the target object file format.
4504 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
4506 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
4507 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
4509 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
4511 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
4512 * TODO: We did a few things, we have more to do though.
4514 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
4515 * inflow.c (inferior_died): Clear deferred stores.
4517 * Debug problems with dummy frames and calls to the inferior.
4518 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
4519 * sparc-tdep.c (do_restore_insn): Simplify.
4520 (sparc_frame_find_saved_regs): Simplify and fix what we find.
4521 (sparc_push_dummy_frame): Simplify and fix what we push.
4522 (sparc_pop_frame): Slightly more hair here, deciding whether
4523 we are restoring a saved PC or returning to a return address in %i7.
4524 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
4526 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
4527 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
4528 * obstack.h (chunkfun): ditto.
4529 * defs.h (xmalloc, xrealloc): ditto
4531 * utils.c (quit): Grab the terminal from the child if necessary.
4533 * inflow.c (term_status_command): Rename to term_info, change
4536 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
4537 (is_delayed_branch): Speed up.
4538 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
4539 Still missing some float ops, and needs testing.
4541 * Support for input and output radixes other than base 10
4542 * defs.h (input_radix, output_radix): Declare.
4543 * expread.y (yyparse, parse_number): Handle changes of input
4544 radix, and ambiguous names-or-numbers in radixes >10.
4545 * printcmd.c (print_scalar_formatted): Print formatted hex
4546 numbers in varying column widths.
4547 * valprint.c (val_print): Use output_format to print scalar ints.
4548 (set_input_radix, set_output_radix, set_radix): Create.
4549 (set_output_radix): Set output_format from output_radix.
4550 (_initialize_valprint): add `set radix' but leave the others off.
4552 * main.c (execute_command): Let stupid questions be turned off.
4553 (_initialize_main): Handle "set stupidity", etc.
4555 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
4556 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
4558 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
4560 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
4561 bfd stuff is still screwed up, but with some manual work, it
4564 * breakpoint.c (bpstat_do_actions): Start over if a command
4565 proceeds the inferior, since the inferior will have stopped and
4566 will need to have its new stop-actions taken care of.
4568 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
4569 compiler fits, simplify it.
4571 * gdb.texinfo (directory command): Doc new dir command.
4572 source.c (directory_command): "dir" now puts things on the front
4573 of the path, moves dups up front, and handles multiple names
4574 on the command line, inserting each one in order. It also
4575 blows away cached line and full_filename info.
4577 * stack.c (backtrace_command): Skip "more stack frames follow"
4580 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
4581 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
4582 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
4583 The only odd one was Gould NP1, which had defined vprintf to
4586 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
4587 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
4588 variable, inspect_it.
4589 valprint.c (print_string, val_print): Use the global inspect_it
4590 to indicate whether to print in Epoch style or normal style.
4592 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
4594 * printcmd.c (call_command): add an alias for the "print" command
4595 which runs expressions and doesn't print the result if void.
4596 (print_command_1): implement it.
4598 * command.c: Remove #if 0'd code. Initialize all the fields
4599 in add_cmd (). Rename do_nothing_command to
4600 not_just_help_class_command, and make it externally visible.
4601 command.h: add user_commands to struct.
4602 * main.c (define_command): Don't overload c->function with a char
4603 string as well as a function pointer.
4605 * eval.c (evaluate_subexp): Reinstall tiemann changes to
4606 calling convention of value_struct_elt () that got dropped in
4609 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
4610 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
4612 * tm-sparc.h (POP_FRAME): replace some constants with defines.
4614 * sparc-xdep.c (store_inferior_registers): defer stores to regs
4615 until a good time (e.g. when we are about to run the child),
4616 saving ptrace calls.
4617 * infrun.c (proceed): handle DO_DEFERRED_STORES.
4618 * tm-sparc.h: define DO_DEFERRED_STORES.
4620 * sparc-xdep.c (store_inferior_registers): when storing float
4621 registers, don't store stack regs too. When storing the SP,
4622 however, DO store the stack regs too. This fixes a bug in which
4623 the dummy frame is not recognized when a call_function finishes,
4624 because its frame pointer (in the stack regs) was never
4626 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
4627 even though we don't know how to read them from an inferior.
4628 valops.c (call_function): Comment about storing SP.
4630 * infrun.c (save_inferior_status): Save away the original bpstat
4631 chain so it can be restored later. Install the copied version for
4632 use by whoever saved the status. It will be blow away by
4633 restore_inferior_status, and the original chain restored. This is
4634 important for people who have pointers into the original.
4636 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
4637 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
4638 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
4641 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
4643 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
4644 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
4645 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
4647 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
4649 * Merge Mike Tiemann's multiple inheritance changes from Sun.
4650 Store the baseclasses in a type struct starting from array element
4651 0 rather than from the unusual array element 1.
4653 dbxread.c: the above.
4654 (virtual_context): Add
4655 Read new debug information about which virtual function table
4656 a virtual function is from, and store it in fn_field.fcontext.
4658 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
4659 TYPE_FN_FIELD_STATIC_P.
4661 symtab.c: the above.
4662 valops.c: the above. Handle pointer casts of object *'s.
4663 (search_struct_method): Add.
4664 (value_struct_elt): First arg is now a pointer to a value, and is
4667 valprint.c: the above.
4668 values.c (value_virtual_fn_field): Add type arg. Handle
4669 offsetting to the proper object when calling virtual fns.
4671 (baseclass_addr): Add valuep arg.
4673 * README: Document the current state of BFD config (missing).
4674 * TODO, ChangeLog, Makefile.dist: Roll version.
4675 * WHATS.NEW: Add summary of changes since 3.5.
4677 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
4679 * dbxread.c (read_struct_type): Clear bit vectors whenever
4681 symtab.c (B_CLRALL): define.
4683 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
4684 using == rather than =. Huh... This fixes the dreaded problem
4685 wherein builtin_type_int becomes TYPE_CODE_FLT.
4687 * core.c (info_files): Show the inferior pid.
4689 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
4690 already knows how to look in the source directory.
4692 * Remove psymtab hair from many places. Remove duplicated code
4693 for searching symbol tables. Hide psymtabs from most places.
4694 Make it fast to get from a psymtab to its symtab.
4696 blockframe.c (blockvector_for_pc): Remove psymtab hair.
4697 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4698 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4699 dbxread.c: export psymtab_to_symtab, make it work if called N times.
4700 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
4701 new symtab completely. New psymtabs get symtab pointer
4702 initialized to zero. Remove MI warning printf.
4703 symtab.h: Comments. Add psymtab to symtab pointer.
4704 (PSYMTAB_TO_SYMTAB): New macro.
4705 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
4706 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
4708 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
4710 (print_frame_info): Avoid special-casing symbols that have not yet
4713 * source.c (open_source_file): Quick path if we have already
4714 located the source file by its full name.
4716 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
4717 find_pc_psymtab. When a name is found in the misc function
4718 vector, search the symbol table for its mangled name, not the
4719 name that the user typed.
4721 * bfd.h: Fix missing comment terminators, make #endifs match.
4723 * valarith.c (value_less): Handle unsigned int comparisons.
4724 Add FIXME about pointer compares, which assume host and target
4725 pointers are the same.
4727 * command.c (do_nothing_command): lint
4728 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
4729 fix comments on debug symbol format for visibility. Actually set
4730 visibility of symbols.
4731 main.c (echo_command): lint; use <readline/history.h>.
4732 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
4733 obstack.h (_obstack_blank): Rearrange pointer math to avoid
4734 pointing past end of allocated memory; saber complains.
4735 obstack.h: Declare the external functions that we use.
4736 valarith.h: use <string.h>
4737 solib.c (solib_add): lint.
4739 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
4741 * main.c (initialize_main): Default info_verbose to off, now that
4742 symbol reading is fast.
4743 (quit_command): Avoid clobbering exec_bfd while quitting.
4745 * Initial BFD (binary file diddling library) merger:
4746 coffread.c: Change AOUTHDR to struct exe_hdr.
4748 core.c: initialize initialized data at compile time.
4749 (core_file_command): Move from coredep.c, convert to bfd.
4750 (xfer_core_file): Convert to bfd.
4751 exec.c (exec_file_command): use bfd routines.
4753 mips-tdep.c: Remove exec_file_command and friends.
4756 * coredep.c: (fetch_core_registers) Convert core_file_command to
4757 fetch_core_registers.
4758 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
4760 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
4761 (my_bfd_read): More bogosity, which I don't think we call.
4762 (program_name): Remove this atrocity asap!
4764 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
4767 values.c: allocate_repeat_value was not clearing the
4768 optimized_out field.
4769 (value_static_field): minor stylistic fix (wrong macro was used).
4770 valops.c (value_struct_elt_for_address): didn't work for C++
4773 * signame.c (_initialize_signame): Initialize signal names once.
4775 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
4776 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
4777 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
4779 * remote-eb.c: Support user-settable baud rates on the serial port.
4781 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
4783 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
4785 * tconfig/sun3os4: Remove warning about native assembler,
4786 since it also occurs in the xconfig file.
4788 * findvar.c (registers): Allocate some slop after `registers'
4789 to prevent stray accesses from trashing the next variable.
4791 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
4792 on the sun-3, by changing the #ifdef from `sun3' (which is not
4793 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
4794 vars, which happened to follow `registers' in the executable.
4796 * readline/history.c (history_search): Heed gcc-2's advice
4797 and parenthesize && inside ||).
4799 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
4800 tm-29k.c: Insert FSF copyright headers.
4802 * remote-eb.c: Better comments.
4804 * Makefile.dist: Update to 3.91.6.
4805 * TODO: note PREPARE_TO_STORE problem.
4807 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
4809 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
4811 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
4813 * infrun.c (wait_for_inferior, at end): Don't set up
4814 prev_* if the inferior no longer exists.
4816 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
4817 CANNOT_EXECUTE_STACK.
4818 valops.c (call_function): Use it.
4820 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
4822 * inferior.h (PC_IN_CALL_DUMMY): New macro.
4823 infrun.c (wait_for_inferior, 2 places): Use it.
4825 * values.c (value_being_returned): Only use
4826 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
4828 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
4829 right thing for remote-eb.c.
4831 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
4832 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
4834 * blockframe.c: Put get_frame_saved_regs inside #if !defined
4835 (FRAME_FIND_SAVED_REGS).
4837 * findvar.c ({fetch,store}_registers): Check for
4838 REMOTE_{FETCH_STORE}_REGISTER macro.
4840 * findvar.c (get_saved_register): Add argument lval and
4841 change meaning of argument addr.
4842 findvar.c: Change calls to get_saved_register to reflect
4843 new calling convention.
4844 valops.c (value_assign): Use get_saved_register instead of
4845 find_saved_register.
4847 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
4849 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
4850 an (uninitialized) pointer to one. Use "&" when passing it
4853 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
4855 * coffread.c (getfilename): Use DGUX x_offset and x_name if
4858 * coffread.c (symbol_file_command): Put semicolon after
4860 Put safe_to_init_tdesc_context in #if defined (TDESC).
4861 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
4862 coffread.c: #include <sys/stat.h>.
4863 (read_coff_symtab): Typo: in_source_files -> in_source_file.
4864 Add missing ')' in check for "lc%" and friends. Remove
4866 Declare read_one_sym() at top of file.
4867 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
4868 MC68WRMAGIC can have the same value without causing a duplicate
4871 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
4873 * Allow a Makefile to be built without building the
4874 tm and xm file links that screw up builds in subdirectories.
4875 This is done with `config.gdb none', then you can do things
4876 like `make gdb.tar.Z'.
4877 * tconfig/none: Config file for no target system
4878 * xconfig/none: Config file for no host system
4879 * config.gdb: If no TM or XM files are called out by the
4880 host or target file, don't make links for them.
4882 * cplus-dem.c: Add documentation.
4884 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
4885 simple error, so the user's gdb doesn't crash due to some object
4886 file problem (e.g. somebody is rebuilding the file out from under
4889 * printcmd.c (print_address_symbolic): demangle the symbol.
4891 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
4892 Motorola copyrights in it. Make "make gdb.tar.Z" work.
4893 (alldeps.mak): sort and uniq all results from this; duplicates
4894 hose gdb.tar.Z link building. Remove RCS files from
4895 tconfig and xconfig. Add config files for sun386. Add
4896 a few odd files to OTHERS and HFILES.
4898 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
4900 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
4901 Roll version number to 3.91.5. Make lint work in bindir.
4903 * README: Document cross-debugging and new file structure.
4905 * blockframe.c: Lint. Include "value.h" to declare read_register.
4906 (find_pc_partial_function): remove duplicate line.
4908 * command.h: Lint. Declare error_no_arg and dont_repeat.
4910 * tm-news.h: Remove inadvertently duplicated stuff.
4912 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
4913 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
4915 * config.gdb: Allow `config.gdb host target' form. Clean
4916 up previous change that printed bogus messages when you just said
4919 * core.c: #include "command.h" for lint.
4922 * main.c: Remove some casts of enums. Lint.
4929 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
4931 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
4932 read it from memory. This will allow us to save ptrace calls
4933 eventually. Changed caller single_step too.
4935 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
4936 that we aren't going to use, saving many ptrace calls, especially
4937 when watchpointing or single stepping. Use some #define's for
4939 (store_inferior_registers): Ditto.
4940 (core_file_command): Use some #define's for constants.
4942 * tm-sparc.h: Add #define's for some register numbers, so we
4943 can eliminate the use of random constants in sparc-xdep.c.
4945 * stack.c (frame_command, print_frame_info, up_command,
4946 down_command) Remove frame_changed, since it
4947 causes a bug and doesn't seem to do anything useful. In some
4948 places it was used as a flag, in others as a stack level (?).
4950 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
4951 default is to use the portable (vprintf) version rather than the
4953 * xm-news.h (MISSING_VPRINTF): Add.
4955 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
4957 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
4959 * Remove stuff that forces -Bstatic linking of gdb, and warnings
4960 about linking debugged programs -Bstatic in the sun?os4 config
4961 files in tconfig and xconfig subdirectories.
4963 * main.c (main): Remove unreached exit(0) now that we exit
4966 * Create TODO file for online bug list. There are too many
4967 "little" bugs to keep track of on paper.
4969 * Change Projects file to refer to bug-gdb@cygnus.com
4970 rather than kingdon@ai.
4972 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
4974 * Makefile.dist (VERSION): 3.91.4 now.
4976 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
4977 (condense_misc_bunches): Add sanity check that misc_count is
4978 the same as the number of symbols in the bunch.
4980 * coffread.c: rename init_misc_bunches. Pass an argument
4981 to condense_misc_bunches (a zero).
4983 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
4984 every time we are called; don't rely on our caller to do it.
4985 (add_file): Remove call to init_misc_bunches.
4987 * mipsread.c: Only warn, don't error, if unknown symbol types.
4988 This keeps an old gdb from falling on its face if it sees newly
4989 extended symbol info. Rename init_misc_bunches.
4991 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
4993 * Merge in changes from Per Bothner for DECstations and other
4994 MIPS stuff. The rest is Bothner speaking:
4996 The next message is a merger of Alessando Forin's mips port with
4997 mine. I've tried to use my good if biased judgment to get
4998 the best of both. It *does* need testing.
5000 Some of the changes are general, *not* mips-specific.
5003 Didn't believe in little-endian bit order.
5004 There are still inconsistencies about whether flags
5005 like BITS_BIG_ENDIAN are integer (#if ...) or
5006 boolean (#ifdef ...). I tried to paper over them.
5008 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
5009 Moved some misc_function code that was common to
5010 {dbx,coff,mips}read.c to symtab.c.
5011 In the process, I think I cleaned things up a bit.
5012 At the same time, moved obsavestring and obconcat to symtab.c.
5015 Removed obsolete condense_addl_misc_bunches (use
5016 condense_misc_bunches(1) instead).
5019 Needed to include <sys/dir>, at least on DECstations.
5021 valops.c, mips-tdep.c, tm-mips.h:
5022 Added PUSH_ARGUMENTS macro to support funny argument-pushing
5023 conventions (when STACK_ALIGN is insufficient).
5024 Needed on mips, where doubles need 8-byte alignment,
5025 but ints only need 4.
5028 Removed cruft that was not being used.
5029 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
5032 Print $ before register-names (I think that makes things a little
5034 Never print two instructions, even if one delays.
5035 Removed hex-disassemble set_cmd. (This is not mips-specific,
5036 so I think the argument is whether it is generally worthwhile or not.
5037 I'm inclined to think not, given how easy it is to
5038 convert between radixes in gdb.)
5041 This is basically Alessando's code.
5042 It doesn't use obstacks; I changed it to use obstacks
5043 in a few minor places where using malloc causes a
5044 memory leak. (Probably, more places could/should be changed.)
5045 I added record_misc_function where it was missing.
5046 In symbol_file_command and add_file_command, I tried
5047 to make the code consistent with more recent versions.
5048 Minor sylistic changes in parse_procedure.
5049 Make a .gdbinfo. psuedo-symbol point back to the real
5050 procedure symbol (using the isym field).
5053 This is basically from my port, but with a lot of details
5054 and a number of routines merged in from Alessando's version.
5055 I basically used my code "raw" backtrace (use heuristics
5056 from the actual code, rather than symbol table info) - though
5057 the idea is Alessandro's. I feel my code is a little cleaner
5058 here, particularly in being a little more flexible, such as being
5059 able to handle gcc-produced code (which it now can).
5060 It also doesn't do frame caching (which is not useful
5061 more recent gdb versions).
5062 I also used my code for push_/pop_dummy, more or less.
5063 I tried to incorporate AF's code for testing sigtramp
5064 while backtracing; I probably got it wrong.
5065 Added mips_print_register, which tries to scrunch as much
5066 information as possible on a screen...
5067 Removed the skip-prologue set_cmd. As with hex-disassemble (see
5068 under mips-pinsn.c), I don't see anything mips-specific here,
5069 and I don't see it being all that useful anyway.
5072 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
5073 Use more register names (rather than hard-cases numbers).
5075 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
5077 * Hack up 3.90.11 changes:
5079 * Makefile.dist (depend): parameterize $(GCC).
5080 Add solib.c and solib.o.
5081 (readline): Fix vpath for both absolute or relative SRCDIR.
5083 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
5084 Also, let the part I didn't understand at least compile so
5085 I can test the rest. FIXME.
5087 * dbxread.c: Fix thinko using strcmp.
5088 (init_psymbol_list): declare static.
5089 (partial_symbol_file_open): Comment cleanups better, avoid
5090 cleaning up the string table since the caller will do that.
5091 Move the stat for mod time into symbol_file_command, temporarily.
5092 (There should be a mod time for each symbol file, eventually,
5093 to control its rereading. FIXME.)
5095 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
5096 SunOS, which gives error for shared libs otherwise. (From
5097 Schaefer, probably FIXME needs work for portability.)
5099 * solib.c: Move #include "param.h" to work.
5100 Lowercase all the Uppercase Letters In the Messages.
5101 (find_solib): Clean up inferior_so_name for debug printouts.
5102 Allow no argument, to mean all shared libraries.
5104 * symmisc.c: include param.h to get CLEAR_SOLIB.
5106 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
5108 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
5109 to 3.90.11. ChangeLog entries below are from this.
5111 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5115 * Makefile.dist (HFILES): Add tm-sunos.h.
5117 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5121 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
5123 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
5125 * sparc-opcode.h Added single-operand version of rett.
5127 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5129 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
5130 Put parens around gcc_p in expansion.
5132 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5134 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
5136 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5138 * Changes for Sun shared libraries:
5139 blockframe.c (find_pc_partial_function): If a non-text symbol
5140 is found, set *address = pc - FUNCTION_START_OFFSET.
5141 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
5142 Disable breakpoints instead of giving an error.
5143 source.c (select_source_symtab): Initialize cs_pst.
5144 symmisc.c: Call CLEAR_SOLIB if defined.
5145 symtab.h: Make text{low,high} CORE_ADDR not int.
5146 (psymtab): New field addr.
5148 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
5149 (record_misc_function): Give correct type for N_DATA symbols.
5150 (condense_misc_bunches): do "misc_function_count = j" regardless
5152 Take code which is shared between symbol_file_command and
5153 add_file_command and put it into partial_symbol_file_{open,read}.
5154 Split add_file_command into add_file_command and add_file.
5155 Make psymtab_to_symtab read in the string table if the file
5157 Two new parameters to read_dbx_symtab and start_psymtab.
5158 tm-sunos.h: New file.
5160 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5162 * infcmd.c: Change cont_command to continue_command and "cont"
5165 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5167 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
5169 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
5171 * values.c (USE_STRUCT_CONVENTION): Check for structures of
5172 size 1,2,4,8 rather than size < 8.
5174 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
5175 as necessary, not just once.
5177 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
5179 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5181 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
5183 * tm-news.h: Add CALL_DUMMY_*.
5185 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
5187 * config.gdb: In list_host, list_target, use ${i}, not $i.
5189 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5191 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
5193 * sparc-opcode.h: Change all store floating-point state register
5194 instructions to have the right match & lose fields.
5196 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5198 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
5200 config.gdb: If srcdir != ., create readline directory and
5201 copy a makefile into it.
5203 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
5204 consistency with POSIX.
5206 * breakpoint.c (bpstat_stop_status): Disable watchpoint
5207 when we exit its exp_valid_block.
5209 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
5211 * Makefile.dist: Bump version to 3.91.3.
5213 * Clean up handling of breakpoint commands (somewhat).
5214 Prompted by Tiemann bug report "cont 10" doesn't work any more.
5216 inferior.h: Add breakpoint_proceeded to inferior status struct
5217 and globals; save it and restore it.
5218 (clear_breakpoint_commands): Cleanup, remove old #define.
5220 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
5221 (save_inferior_status, restore_inferior_status): handle it also.
5222 (proceed): Remove earlier code that set breakpoint_proceeded.
5223 It is now set only in clear_proceed_status.
5224 (clear_proceed_status): Cleanup, use bpstat_clear rather
5225 than clear_breakpoint_commands. No callers need the stop_bpstat
5226 between clear_proceed_status and proceed.
5228 infcmd.c: Add breakpoint_proceeded definition and comment.
5229 (cont_command, jump_command, signal_command): Move call to
5230 clear_proceed_status right next to call to proceed.
5232 breakpoint.c (bpstat_do_actions): Avoid clobbering our
5233 caller's argument while running down the chain of breakpoints.
5234 Use new variable "breakpoint_proceeded" to determine when
5235 a command that it executes moves the inferior past the
5237 (bpstat_clear): Handle NULL argument.
5238 (bpstat_clear_actions): Avoid useless call to
5239 breakpoint_auto_delete.
5240 (delete_breakpoint): Clean up bpstat's that are pointing to
5241 the deleted breakpoint from the stop_bpstat chain.
5242 (breakpoint_auto_delete): Simplify.
5244 * Clean up handling of EOF, error on stdin, etc. This was
5245 prompted by a network problem that caused gdb to go into an
5246 infinite loop filling up its malloc'd memory.
5248 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
5249 not clear_breakpoints_commands, which is now gone.
5250 (main): If command_loop returns (e.g. from EOF on stdin), do
5251 a quit_command (looping back to command_loop if quit_command
5252 doesn't really quit).
5253 (command_loop): check result from command_line_input and
5254 exit if it returns NULL, rather than passing the NULL to
5256 (gdb_readline): Free malloc'd result space before returning
5259 * utils.c (query): Handle C-d to mean "yes", just as if the
5260 input was not a terminal. Also avoid infinite loop if EOF
5261 occurs in mid-input-line before newline. This allows
5262 query to be used at EOF on stdin with reasonable results.
5264 * infrun.c (proceed): Set breakpoint_proceeded.
5266 * values.c (value_as_long): Avoid infinite recursion for enums.
5267 (_initialize_values): Fix typo in help msg (kingdon).
5269 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
5270 RL_LIB for linking. This allows -lreadline for linking
5271 and nothing for dependencies, once readline is a real library.
5273 * config.gdb: Jim Kingdon: give useful error message if the
5274 host or target type is not recognized.
5276 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
5277 it just defines it. Dumb, but deal with it.
5279 * Jim Kingdon suggests:
5280 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
5282 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
5284 * Makefile.dist (VERSION): Bump version # to 3.91.2.
5286 * Clean up Bothner's changes.
5288 * blockframe.c (clear_pc_function_cache): New function.
5289 * blockframe.c: remake cache_pc_function_* static.
5290 * dbxread.c (symbol_file_command): remove references to
5291 cache_pc_function_* variables.
5292 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
5293 * printcmd.c: Avoid kludging a global variable (addressprint)
5294 to avoid printing the address of a string twice. Instead,
5295 pass the format letter 's' down low enough that it can be seen
5296 to avoid this problem.
5297 (print_formatted): Pass format arg to value_print.
5298 (restore_addressprint): Remove function.
5299 (do_examine): Avoid hacking addressprint, cleanups and such.
5300 (print_frame_args): Add a comment to a Bothner change.
5301 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
5302 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
5303 to wipe out the values cached in blockframe.c.
5304 * symtab.c (find_method): Add comment saying how big you must
5305 allocate to be "big enough". Per being terse again.
5306 * valprint.c (val_print): Handle format letter "s" to print
5307 strings without addresses. Add comment to vtbl printing code
5308 which casts with wild abandon. Rearrange reference-printing
5310 @0xaddr: value (print w/addressprint)
5311 value (print w/~addressprint)
5312 @0xaddr (parameter lists w/addressprint)
5313 or nothing (parameter lists w/o addressprint)
5315 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
5317 * Merge more changes from Per Bothner:
5319 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
5320 annoying) that I tried to improve it. Here are my suggestions.
5322 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
5325 Do automatic de-reference when taking the address of a reference.
5327 Don't deref_ref when printing parameter lists.
5329 More attempts at treating refernences properly.
5331 In val_print, if deref_ref==0, don't print dangling " = ".
5333 Add COERCE_REF macro, which de-references an REF.
5335 * Merge changes from Per Bothner:
5337 * Fixed (Sony news)-specific configuration problems.
5338 * Fixed other problems with using vanilla pcc and libc (enum problems;
5339 assumption that vsprintf exists).
5340 * Some major speed-ups (finc_pc_partial_function now caches a match;
5341 parsing avoids duplicate symbol_lookup calls).
5342 * Changed handling of baseclasses (no longer use baseclasses field
5343 of struct type, use the first n_baseclasses fields instead).
5344 * Various minor changes/fixes, most C++-related.
5347 Cache the most previous match from find_pc_partial_function.
5348 (Save both low and high ends of matching function's pc range.)
5349 This speeds up the loop of infrun.c:wait_for_inferior quite
5350 a bit, and makes step/next commands much zippier.
5352 Added an enum->int cast (otherwise, some compilers barf).
5354 No longer set baseclass offset to 0, since multiple
5355 inheritance now mostly works.
5356 Added a number of casts, to shut up compiler warnings
5357 (after stabs where made enums, not ints).
5358 When discarding a symbol table (in symbol_file_command),
5359 must clear the cache introduced in blockframe.c.
5360 Don't convert $vtbl_ptr_type to vtbl any more.
5361 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
5362 Mask off sign bit emitted by g++ for virtual table offset.
5363 Set voffset to -1 (not 1) for static member functions.
5365 Changed parsing/lexing of names to avoid doing symbol lookup twice
5366 (once when lexing to determine symbol class, once for real).
5367 Now only call symbol_lookup once. Fields of 'this' win especially big.
5369 Subpress printing addr twice in the case of 'x/s addr'.
5371 lookup_basetype_type is no longer used.
5372 Add find_methods as recursive helper function to decode_line_1.
5373 This allows multiple inheritance to work.
5374 Also, once one or more matches has been found, do not look in
5375 base-classes. (Baseclass methods would be overridden, anyway.)
5377 Removed baseclasses array in struct type.
5378 Instead of using baseclasses[i], use fields[i-1].
5379 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
5380 Changed sign convention of voffset (previous was inconsistent).
5382 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
5384 Used to assume existence of vsprintf. Re-written to not need it
5385 if HAVE_VPRINTF is undefined.
5387 typecmp was too pessimistic. Made it less so.
5389 Don't print space after address.
5390 If vtable points to a misc symbol (with 0 offset), print it,
5391 since that indicates the actual class of the object.
5392 Changed ype_print_derivation_info to use new inheritance
5393 scheme (without baseclasses vector).
5395 In value_primitive_field, fixed some bugs left over from previous set of fixes.
5396 Also, changes needed because TYPE_BASECLASSES were removed.
5398 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
5400 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
5403 If there is no path set, and the symbols don't indicate what directory
5404 a file was compiled in, look in the current directory. But either
5405 a path or a known compilation directory will prevent this.
5408 Three independent bug fixes:
5409 * Remove the #if 0 block that breaks some stuff.
5410 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
5411 adapt gdb to either SunOS 4.0.* or 4.1.
5412 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
5415 Instantiate the class T when looking for methods in it. (Tiemann@sun)
5418 (type_print) Demangle the name being printed.
5419 (type_print_base) Handle botched demangling without coredump (tiemann).
5422 (check_stub_method): Document routine.
5423 (tiemann) fix bug for no-arg functions
5424 Avoid clobbering beyond end of malloc'd storage.
5425 Terminate the argument list properly.
5427 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
5429 * Changes merged by John Gilmore:
5432 In breakpoint_1, use new print_address_symbolic instead
5433 of find_pc_partial_function. (This forces use of assembler-level
5434 addresses, and avoids misleading non-mangled source-level names.)
5436 Generalize ansi argument such that -1 means skip arglist totally.
5437 Removed global variable print_ansi_qualifiers (which made
5438 code non-reentrant), in favor of extra explicit arguments
5439 to internal routines.
5441 Add new helper function print_address_symbolic.
5442 Use find_pc_misc_function instead of find_pc_partial_function
5443 (since we want assembler-level symbols here).
5445 Print unknown function as just "f (...)", not "f (...) (...)".
5446 Use new fputs_demangled explicitly.
5448 Fixed a typing violation (problem: value.h cannot be imported
5449 without renaming many variable in this file).
5450 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
5451 decode_line_1: Moved forward some never-reached code.
5452 Made decode_line_2 skip function prologues correctly.
5454 fputs_filtered should not demangle by default.
5455 Add new fputs_demangled to demangle on demand..
5457 Change value_struct_elt to use value_primitive_field (using recursive
5458 utility function search_struct_field). This allows foo.bar to work
5459 for multiple inheritance (so far only for data fields).
5460 Change check_field in the same way (recursive helper function
5461 to support multiple inheritance).
5462 (Note: there are more of these problems that I haven't fixed.
5463 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
5464 value_of_this: 'this' symbol name is now just "this", note "$this".
5466 Don't print static members.
5467 Avoid printing "members of <type>" if there are none.
5468 Simplified type_print_derivation_info by merging duplicate code.
5469 Remove useless blank lines in type_print_base (ptype command).
5471 Added declaration of new routine value_primitive_field.
5473 Added value_primitive_field which is generalized version of

5479 * infcmd.c -- insert else to avoid 'delete env' coredump when you
5480 delete the whole environment. Karl Berry reported the bug.

5482 trigger an Emacs bug causing it to not be able to find files
5483 when running gdb in a window.
