1 Fri Oct 11 23:27:06 1991 John Gilmore (gnu at cygnus.com)
3 * copying.awk: Filter formfeeds out of copying & warrantee.
4 Make them available as `show copying' and `show warrantee' also.
6 Thu Oct 10 17:25:47 1991 John Gilmore (gnu at cygnus.com)
8 * mach386-xdep.c: Even when cross-compiling, leave in the
9 core-file reading code.
10 * core.c (get_core_registers): Avoid coredump if no .reg section.
12 Wed Oct 9 17:03:34 1991 John Gilmore (gnu at cygnus.com)
14 * mipsread.c, coffread.c: initialise TYPE_VPTR_FIELDNO to -1.
15 This avoids coredumps under `set print object on' in value_headof
16 (called erroneously by value_from_vtable_info) for `p &struct'
17 or `p *struct'. From Peter Schauer.
19 Mon Oct 7 00:06:52 1991 John Gilmore (gnu at cygnus.com)
21 * Makefile.in: Roll version to 4.1.2.
22 * dbxread.c: Use aout64.h, not a.out.gnu.h. Get external symbol entry
23 size from BFD (but, FIXME, we don't yet read external nlists's and
24 convert them to internal nlists's before handling them -- we still
25 assume they have the same size and alignment.) Use SET_NAMESTRING
27 * exec.c (exec_file_command): Move dead coff-encapsulation code
29 * m88k-tdep.c, m88k-xdep.c: Remove encap test and #inc <a.out.h>.
31 Fri Oct 4 22:30:06 1991 John Gilmore (gnu at cygnus.com)
33 * configure.in, tm-i386v.h, xm-i386v.h: Intel 386 Mach host port.
34 * xm-i386mach.h, mach386-xdep.c, xconfig/i386mach: New files.
36 Fri Oct 4 17:04:31 1991 Per Bothner (bothner at cygnus.com)
38 More patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
39 * mips-xdep.c (store_inferior_registers): Don't try to
40 write the (pseudo) FP.
41 * mipsread.c (parse_partial_symbols): Improved algorithm for
42 setting pst->texthigh.
44 Fri Oct 4 16:47:32 1991 Roland H. Pesch (pesch at cygnus.com)
46 * doc/Makefile: make TEXINPUTS include . everywhere
48 Fri Oct 4 00:35:56 1991 John Gilmore (gnu at cygnus.com)
50 * coffread.c, dbxread.c, symfile.c, symmisc.c, symtab.h: Remove
51 vestiges of typevectors, which were for symsegs and are no longer
52 used. (From a question by Eliot Dresselhaus
53 <dresselh@RFT30.nas.nasa.gov>).
55 Thu Oct 3 09:33:26 1991 John Gilmore (gnu at cygnus.com)
57 * dbxread.c, coffread.c: static-ize functions that were
58 gratuitiously external. (From Fred Fish.)
60 * c-exp.y: sym->class to SYMBOL_CLASS (sym).
62 * dbxread.c (dbx_lookup_type): Keep doubling size of typevector
63 until it is large enough.
65 * dbxread.c (read_type): Handle error case slightly better.
66 Make complaint message not C++-specific.
68 Wed Oct 2 17:21:07 1991 Stu Grossman (grossman at cygnus.com)
70 * infrun.c (wait_for_inferior): Fix step/next so that you only
71 stop at the beginning of a new line. This fixes various problems
72 with for loops, nested if-else's and switch statements.
74 Tue Oct 1 06:33:55 1991 John Gilmore (gnu at cygnus.com)
76 * symtab.c (lookup_symtab_1, lookup_symbol): "fatal" errors
77 between symtabs and psymtabs become ordinary error()s.
79 * dbxread.c (read_dbx_symtab): Relocate end_of_text_addr
80 properly, making "end pc" correct in shared lib psymtabs.
81 (From Guy Harris <guy@auspex.com>.)
83 Mon Sep 30 13:15:31 1991 John Gilmore (gnu at cygnus.com)
85 * dbxread.c: Enable, but soften, const_vol_complaint.
86 (read_dbx_symtab): N_STSYM and N_LCSYM define static vars.
87 Ditto Gould N_NBSTS and N_NBLCS. Also, all types in the psymtab
88 should be file-scope, not global.
89 (read_struct_type): Remove ancient multiple-inheritance warning.
90 (read_range_type): Check base type, complain & patch if undefined.
91 * stack.c (frame_info): Demangle the function name in `info stack'.
94 Sat Sep 28 10:02:33 1991 John Gilmore (gnu at cygnus.com)
96 * eval.c (evaluate_subexp_for_address): Don't use
97 TYPE_POINTER_TYPE directly (it might be zero if this type has
98 never had a pointer created before); use lookup_pointer_type.
99 * symtab.c (lookup_method_type): Arguments were swapped in all
100 callers, so fix it here. I'm amazed this worked at all!
102 Fri Sep 27 18:09:31 1991 John Gilmore (gnu at cygnus.com)
104 * c-exp.y, m2-exp.y: Define more yysymbols that happen to be
105 "bss" rather than "data" symbols, but which still conflict.
108 * coffread.c (coff_symfile_read): Use xmalloc, not malloc.
109 * core.c (core_files_info): Shorten output.
110 * exec.c (exec_files_info): Ditto.
111 (build_section_table): Ignore zero-length sections.
112 * language.c, printcmd.c: Lint.
113 * language.h (get_frame_language): Declare.
114 * saber.suppress: update.
115 * stack.c (find_relative_frame): Remove complex code that was
116 #if 0'd, stick with simple code. Lint.
117 * saber.suppress: Update a bit.
118 * symfile.c (add_symbol_file_command): Add "?" to question.
119 * utils.c (parse_escape): Avoid \a due to bdead compilers.
120 * value.h: Declare typedef_print.
122 * valprint.c (val_print, type_print_base): TYPE_CODE_RANGE less
125 * nindy-tdep.c (nindy_frame_chain_valid): Use lookup_misc_func.
126 (Reported by Mark Peek <mark@imagen.com>.)
128 * solib.c (solib_map_sections): Relocate all sections, even
129 though only the text section's size is tracked. Mark ld_text
130 for eventual elimination as we generalize to N sections.
132 * infrun.c (wait_for_inferior): Don't check if the PC is in a
133 call_dummy if we were stopped by a random signal that is being
134 passed to the program. This produced wierd results when calling
135 functions in the inferior and signals (e.g. SIGALRM) were in use.
137 Tue Sep 24 18:05:30 1991 John Gilmore (gnu at cygnus.com)
139 * infrun.c (IN_SIGTRAMP): Not parenthesized properly.
140 Bugfix from Paul Eggert <eggert@twinsun.com>.
141 * tm-ultra3.h (IN_SIGTRAMP): Ditto.
142 * valprint.c (print_floating): Print 9 digits for IEEE floats.
145 Mon Sep 23 15:50:07 1991 John Gilmore (gnu at cygnus.com)

151 Fri Sep 20 16:10:52 1991 John Gilmore (gnu at cygnus.com)
155 * Makefile.in (VERSION): Set to 4.1.
156 * language.c (set_language_command): Print useful help message,
157 and restore the language string after giving help.
158 * valprint.c (typedef_print): Print typedef in C or M2.
159 * symtab.c (list_symbols): Use it.
160 * main.c (main): Avoid any output before (gdb) prompt when -q.
161 * language.c (set_language_command): Handle errors by restoring
162 the language string to its current state (fix from A. Beers).
163 * doc/gdbint.texinfo: Roll in information from README. Rearrange
164 "how to install" and "how to print the doc" stuff so it drops
166 * configure.in: Rename rtpc CPU to romp to match config.sub.
167 * README, WHATS.NEW, TODO: Update for gdb-4.1.
169 Fri Sep 20 17:39:14 1991 Roland H. Pesch (pesch at cygnus.com)
171 * doc/gdb.texinfo: Updates from ChangeLog. set/show write,
172 autoloading shared libs, copyright etc on GDB startup, clean up $_
173 and $__ index refs, set/show listsize and related updates to list
174 cmd. New host/target configs.
176 Fri Sep 20 15:46:00 1991 Roland H. Pesch (pesch at cygnus.com)
178 * doc/Makefile: generate aux version-no file doc/gdbVN.m4
179 from main Makefile.in version definition
180 doc/gdb.texinfo: use version recorded in doc/gdbVN.m4 for current
182 Makefile.in (setup-to-dist): generate doc/gdbVN.m4
184 * doc/gdb.texinfo: merge new language-switching and lang-specific
187 Fri Sep 20 15:00:57 1991 Per Bothner (bothner at cygnus.com)
189 * mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
190 compilers (which may lack stddef.h).
192 Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com)
194 * dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and
195 N_WARNING are the same except for the N_EXT bit, so just use their
196 values alone, rather than OR-ing them with N_EXT.
198 Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com)
200 * mipsread.c (parse_lines): Deal with negative extended line
203 * c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid
204 global symbol conflicts.
206 Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
208 * .gdbinit: Move 'set complaints' to top, so it runs even in
209 case we aren't debugging GDB.
210 * language.c (_initialize_language): Fix type check and range
211 check documentation strings.
212 * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
213 language.c can use it. (Though language.c should really not be
214 handling warnings/errors the way it does, FIXME.)
215 * symtab.c (lookup_primitive_type): const lint.
217 Bugfix from Peter Schauer:
218 * source.c (lines_to_list): Make signed, to avoid comparison
219 going unsigned and complaining that -3 is too high for 21 lines.
220 * stack.c (lines_to_list): Ditto.
222 Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
224 * Makefile.in (HFILES): Add minimon.h.
225 (VERSION): Roll version number to 4.0.95.
226 (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
227 New rules for building distributions. Normal distribution
228 is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
229 one level up from here; it calls make-proto-gdb.dir to build a
230 directory `proto-gdb' which is an image of the release. The old
231 `gdb.tar.Z' rule still works too.
232 * config.sub, configure: Roll in latest from ..
234 Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
236 * doc/gdbint.texinfo: Reorder contents; reorganize new-host,
237 new-target, and new-config chapters; fix minor typos; come closer
238 to usual GNU markup conventions for @file @samp @code @var.
240 Thu Sep 19 17:04:12 1991 Per Bothner (bothner at cygnus.com)
242 Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
243 * mipsread.c (parse_partial_symbols): Enter the name of all
244 structs/unions... into the psymtab so we can access them if the
245 symtab is not read in.
246 * mips-tdep.c: Remove some unneeded #includes.
247 * xconfig/dec3100: Add HAVE_STRSTR.
249 Thu Sep 19 15:14:23 1991 John Gilmore (gnu at cygnus.com)
251 * Makefile.in: Circumvent Sun Make bug on *-exp.tab.o.
252 * c-exp.y, m2-exp.y: Lint.
253 * m2-exp.y: Avoid using yytname[] which is a Bison-ism.
254 * valprint.c (val_print_fields): Check for stub type.
255 * mipsread.c (_initialize_mipsread): Avoid using
256 builtin_type_void at initialize time.
257 (mipscoff_symfile_read): use it now.
259 Wed Sep 18 15:55:51 1991 John Gilmore (gnu at cygnus.com)
261 Merge multiple-language support, and partial Modula-2 support,
262 from Andrew Beers <beers@cs.buffalo.edu>.
264 * i387-tdep.c: New file, consolidates most 80387 support,
265 and eliminates host dependency on double<->extended conversions.
266 * i386-xdep.c, symm-xdep.c: Remove most 387 support.
267 * xconfig/i386{sco,v,v-g,v32,v32-g}: Now need i387-tdep.o.

277 code for saving types of parameters with each function definition.
278 * dbxread.c (define_symbol, function and parameter cases): Ditto.
279 (read_dbx_symtab, case N_DEFD): Ignore.
280 (read_enum_type): Recognize FALSE/TRUE enum as Modula-2 BOOLEAN.
281 (read_range_type): Rename MAX_OF_TYPE to MAX_OF_C_TYPE, etc.
282 #if 0 out its uses, though, since they set a dead value.
283 * coffread.c (end_symtab): Use allocate_symtab.
284 (process_coff_symbol): #if 0'd for functions and params as above.
285 (read_enum_type): Recognize Modula-2 BOOLEAN.
286 * symtab.c (add_param_to_type): #if 0'd function to add a
287 parameter type to a function type's field list.

290 * i386-xdep.c, pyr-tdep.c, pyr-xdep.c, remote-vx.c, solib.c,
291 source.c, symfile.c, dbxread.c, breakpoint.c, core.c, exec.c,

293 hex with local_hex_string for Modula-2 support.
295 * breakpoint.c (breakpoint_cond_eval): Use new value_true to test
296 breakpoint condition language-independently.
298 * parse.c: New file with the common code remains of expread.y.
299 * parser-defs.h: New file with common declarations from expread.y.
300 * c-exp.y: New file with the C parser from expread.y, and other
301 language-specific information.
302 * m2-exp.y: New file with the Modula-2 parser and etc.
303 * expread.y, expread.tab.c: Remove.

358 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
360 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
361 entries are enclosed herein. Not all of these changes
362 have been merged into the master GDB sources -- check the
363 ChangeLog above here for the merge log.
365 Mon Jun 3 17:05:45 EDT 1991
367 m2-exp.y Created. Tested outside of GDB for a few days. Proper
368 operators were added, C specific operators and tokens
369 removed. yylex() revamped to some extent. Still things
370 missing from the grammar, such as sets.
371 Tested for two weeks in GDB v3.5.
373 Tue Jun 11 17:23:48 EDT 1991
375 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
376 so they are built-in. Sort of a hack.
378 Fri Jun 14 12:53:51 EDT 1991
380 m2-exp.y Added range checking for numeric constants. Any numeric
381 constant is assumed to be of builtin type INTEGER unless:
382 (1) it is octal or hexadecimal, in which case it is a
383 CARDINAL; (2) it is too big to fit into an INTEGER, in
384 which case it is a CARDINAL.
385 eval.c Added simple range checking for +, -, and * on integers.
386 Doesn't work very well for *, since 6 * 1,000,000,000 =
387 1,705,032,704, which fails the simple test of result >=
388 first_operand, no matter in what order the operands are.
390 Tue Jun 18 14:11:30 EDT 1991
392 Broke the parser into parts, one containing the C grammar and the other
393 containing code to be shared by all of the grammars.
395 The following files no longer exist:
400 The following files were added:
402 c-exp.y (The C grammar)
403 m2-exp.y (The Modula-2 grammar)
404 parser-code.c (Code that is shared by the above grammar)
408 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
409 now necessary to use the Bison compiler compiler, since it
410 will generate function/variable prefixes other than yy.
412 Tue Jun 18 16:47:49 EDT 1991
414 symtab.[ch] Added the external variable working_lang, than holds the
415 value of the current working language.
416 Added the ennumerated type language_mode, with the values
417 language_auto and language_manual, the former meaning that
418 GDB sets working_lang as needed, and the latter meaning
419 that the value of working_lang is totally under user
421 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
422 REAL, BOOLEAN and CHAR. Also added the type codes
423 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
424 utils.c Added set_language_command and show_language_command to
425 implement the GDB support commands "set language" and
427 expression.h A number of identifiers were added to the type exp_opcode
428 to facilitate Modula-2 builtin functions, integer
429 division, and array indexing.
431 Wed Jun 19 13:25:58 EDT 1991
433 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
434 if the language specified by working_lang requires the use
435 of strict typing of expressions. Eventually, even this
436 will be able to be changed by the user.
437 Added the macro RANGE_CHECK, which evaluates to non-zero
438 if the language specified by working_lang requires the
439 checking of a value against the domain of its type.
440 Eventually, even this will be able to be changed by the
442 language.[ch] Predicates involving types (simple_type, ordered_type,
443 same_type, integral_type, numeric_type, character_type,
444 boolean_type, float_type) are added. These predicates are
445 based on the current value of working_lang, and are handy
448 Wed Jun 19 15:39:34 EDT 1991
450 eval.c Added the function type_array_rank which computes the rank
452 valarith.c Added the funtion value_bool, which when given a integer
453 value.h value (ie. struct value *) as an argument, it returns a
454 boolean value (ie. struct value *) true if that integer
455 is non-zero, and a boolean value false otherwise.
456 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
457 will print out properly.
459 Wed Jun 19 16:36:34 EDT 1991
461 valops.c Added the function value_capitalize, which returns it
462 value.h argument capitalized if its argument is a lowercase
463 letter, or the argument unchanged if its argument is not a
465 valarith.c Added the function range_check_p, which returns non-zero
466 value.h if its value argument is between the integral bounds upper
468 Added the function range_check_enum_p, which makes sure
469 that its value argument is a valid member of the domain of
471 Added the function range_check_range_p, which makes sure
472 its value argument lies between the upper and lower bounds
473 of its type argument, which must be a ranged type.
474 Added the function check_array_index, which range and type
475 checks an index of an array.
476 Added the function value_multi_subscript, which computes
477 array[idx1,idx2...idxN], given a value array and an array
478 of values representing indicies.
479 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
480 unpack_long to work with TYPE_CODE_BOOL and
483 Wed Jun 19 18:04:08 EDT 1991
485 symtab.c Stored pervasive types in a structure and make
486 lookup_pervasive_type() a lookup function that was based
487 on working_lang. If lookup_pervasive_type() returned
488 non-zero, then that value was returned (a fix, since
489 before it simply wouldn't return the pervasive type.)
490 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
491 non-zero if the language specified by working_lang means
492 "conversion" when it says "cast".
493 valops.c Added the function value_real_cast(), which performs a
494 value.h *cast*, not a *conversion*, which is what value_cast()
495 does when it can. In particular,
496 value_cast(<float_type>,4) = 4.0, while
497 value_real_cast(<float_type>,4) = some mess.
498 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
499 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
500 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
501 and MIN on integral types. *NOTE*: These are currently
502 hardcoded to work only if there are 8 bits per storage
504 eval.c Made logical functions call value_bool to return a
505 properly typed boolean value, based on working_lang.
507 Thu Jun 20 11:55:27 EDT 1991
509 valprint.c Types now print out in a Modula-2 fashion. This works for
510 the cases when the type is printed out step-by-step, that
511 is, it doesn't work when the name of a structured type
512 (which includes the keyword "struct", etc.) is simply
514 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
515 since type specifications in C and Modula-2 are very
516 different. The C printing of a type is very recursive,
517 whereas in Modula-2 it is generally very simple. C has
518 type prefixes and suffixes, which have no real analogue in
519 Modula-2. Maybe type_print() should call a language
520 specific type printer. This is also advantageous if we
521 compile GDB to exclude some of the languages. We'll just
522 leave those functions out.
524 Thu Jun 20 16:57:10 EDT 1991
526 dbxread.c When reading the complete symbol table in (via
527 psymtab_to_symtab()), the number and types of function
528 arguments are added to a function type. define_symbol()
529 calls add_param_to_type() to accomplish this.
530 Assumption: when we come across a function definition
531 (N_FUN symbol with an 'f' or 'F' in the name), its
532 arguments will appear before another function definition.
533 When a function is found, a pointer to its type is placed
534 in the global in_function_type. Changes that
535 add_param_to_type() makes are to this global.
536 valprint.c The type of a function now includes (for Modula-2) the
537 types of its parameters.
538 eval.c Type checking and a check for the proper number of
539 arguments is now done for function calls. Not sure of the
540 impact this has on C++ member function yet.
542 Thu Jun 20 19:58:48 EDT 1991
544 valprint.c Rewrote the type printer. Broke it into two language
545 specific parts, adding the functions type_print_m2() and
547 An unfortunate consequence is this: if you debugging a C
548 program in Modula-2 mode (why?), info types does not work
549 well with regular expressions, since the types are printed
550 out in Modula-2 terminology, but stored in C terminology.
551 language.[ch] Added the functions new_type_last(), type_keyword(), and
552 type_sep() to aid in the printing of typedefs.
553 symtab.c Made the printing of typedefs as language independent as
554 possible through calls to new_type_last(), type_keyword(),
557 Fri Jun 21 11:50:26 EDT 1991
559 dbxread.c Check all incoming ennumerated types. If it looks like
560 Modula-2's BOOLEAN type, then change the type_code of the
561 type to TYPE_CODE_BOOL so we can process it as a boolean
563 valprint.c Replaced some of the 0x%x with calls to sprintf and
564 hexformat() in val_print().
565 language.[ch] Added the function hex_to_string(), which converts its
566 integral argument to a hexadecimal number (format is
567 language based) and returns the result as a string.
569 Mon Jun 24 12:25:07 EDT 1991
571 valprint.c Some functions call type_print_1() directly, instead of
572 value.h using type_print(), so they can specify where (column) to
573 print things. Since type_print() takes care of language
574 dependence, that needs to be called first. Added a
575 parameter depth to type_print() (so it is now like
576 type_print_1). Changed type_print to type_print_at, and
577 made type_print a macro that passes a depth argument of
579 symmisc.c Changed all calls to type_print_1 to calls to
581 Makefile.dist Made it possible to build GDB for a specific set of
582 depend languages. Do this by passing a definition for the macro
583 LANGS to make. LANGS should be a string containing a
584 space-separated list of language names (ie. LANGS="c m2").
585 The default is to build all languages. Note that grammar
586 files must follow the naming convention of <lang>-exp.y.
587 gdb.lang This holds the current value of the LANGS macro. It is
588 examined every time make is called, and is updated if
590 eval.c Added #ifdef _LANG_<lang> to these files.
591 expread.c Still need to add them to dbxread.c and coffread.c.
599 Mon Jun 24 16:33:11 EDT 1991
601 language.[ch] Added the functions hexformat_pre() and
602 hex_to_string_pre(), which take a prefix argument to
603 include in the format string. Thus, hexformat_pre("08") will
604 return "0x08x" (if the working language is language_c).
605 Made hexformat() and hex_to_string() calls to the above
606 with "" as the prefix argument.
608 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
609 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
610 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
611 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
612 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
613 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
614 valprint.c, vax-pinsn.c
616 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
617 calls to hexformat() and hex_to_string(). Format strings without
618 the leading "0x" were ignored.
620 depend Updated to take the above into account.
623 Tue Jun 25 15:27:18 EDT 1991
625 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
626 and type_check_t to keep track of the current state of
627 range and type checking.
628 main.c Added the variables range_mode, range_check, type_mode,
629 and type_check to record the current state of range and
630 type checking. Added initialization code to main().
631 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
635 Tue Jun 25 17:57:08 EDT 1991
637 dbxread.c process_one_symbol() updates the variable (enum language)
638 source_lang based on the extension of the filename
639 contained in the N_SO sybmol that started this symtab.
640 When end_symtab() is called, the value of source_lang is
641 put into the language field.
642 stack.c select_frame() sets working_lang (and possibly type_check
643 and range_check) to the language field of the symtab
644 associated with the frame that is selected if working_mode
645 is language_auto. If working_mode is language_manual, a
646 warning is printed and working_lang is not set.
647 language.c Added the function set_type_range(), which sets the value of
648 type_check and range_check (if their modes call for
649 automatic setting) based on the current value of
650 working_lang. A non-zero argument will cause the current
651 settings to be output.
654 Wed Jun 26 14:51:40 EDT 1991
656 eval.c Added range checks on assignment.
657 m2-exp.y Added the grammar for sets to the language. Currently,
658 these do not do anything except print an error message.
660 Wed Jun 26 17:01:04 EDT 1991
662 m2-exp.y Added the ability for parse_number() to parse negative
663 numbers. A global flag is set upon encountering a unary
664 minus. This was done to make, for example, 1 parse as a
665 CARDINAL, and not as an integer, per Wirth's examples in
666 Programming in Modula-2 ed.4.
667 valprint.c Added support for "set radix 2" by then setting
668 output_format to 't'.
669 eval.c Implemented range checking on subrange types. Added calls
670 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
671 Implemented MIN and MAX for ennumerated types. The
672 minimum value of an ennumerated type is defined by Wirth
673 as the first identifier, and the maximum as the last.
674 m2-exp.y Made octal numbers ending with "B" be characters and those
675 ending with "C" be numbers, per Wirth's book. (p. 34)
677 Thu Jun 27 14:11:52 EDT 1991
679 stack.c select_frame() now only sets working_lang, it does not
680 notify the user. If working_mode is language_manual, then
681 a warning is issued once.
682 main.c At the end of each call to execute_command(), working_lang
683 is checked against the local static (enum language)
684 current. If they differ and working_mode is
685 language_auto, the new settings of language, type and
686 range checking are printed out.
687 stack.c Modified frame_info() to include the language of the
688 current frame in the output of "info frame".
689 language.[ch] Added the function language_str() which returns the name
690 of the current language.
692 Fri Jun 28 15:33:14 EDT 1991
694 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
695 the language. INCL and DECL currently cause an error,
696 since sets are not implemented yet. INC and DEC are
697 implemented as PREINCREMENT/PREDECREMENT with one
698 argument, and as ASSIGN_MODIFY with two arguments.
699 eval.c Added type checking to the above cases.
700 value.h Added not_lval_constant to the lval_type ennumerated type.
701 not_lval_constant means that the value is a constant
702 value; that is 3 or 'a' or TRUE, not as in a constant
703 identifier. This is used to help coerce numbers such as 3
704 to either signed or unsigned numbers.
705 valops.c Added the function value_coerce_constants() which coerces
706 constant integers as following: if one is a constant and
707 the other is not, the constant's type is set to the type
708 of the other argument. If both are constants and one is
709 signed, the other is converted to a signed constant.
711 Sat Jun 29 17:26:29 EDT 1991
713 valarith.c Added a better range checker. It now checks range
714 (successfully) on integral operations [+-] (signed and
715 unsigned) for any C sized type. Still does not work well
717 int_in_size() returns an integer that is coerced to fit into
718 specified number of bytes.
720 Mon Jul 1 13:04:14 EDT 1991
722 language.[ch] Added the function binop_result_type(), which returns the
723 builtin (struct type *) type that would be the result of a
724 binop on the two values V1 and V2.
726 Wed Jul 3 19:22:53 EDT 1991
728 source.c Extended source_info() to include the source language in
729 the output from "info source".
731 Fri Jul 5 13:48:52 EDT 1991
733 utils.c Moved the support functions for the GDB set/show commands
734 dealing with language into language.c.
735 language.c Added the function language_info(), which displays info
736 about the current working language, type and range check
737 settings. Called via the GDB command "info language".
738 Added an initialization routine _initialize_language(),
739 that sets defaults for the language, type and range
740 variables and sets up the new GDB commands.
741 main.c Language setup moved to language.c.
744 Mon Jul 8 10:10:22 EDT 1991
746 valarith.c Debugged the range checker for arithmetic. Still does not
747 work for multiplication very well.
749 Mon Jul 8 12:40:37 EDT 1991
751 language.[ch] Added the function value_true() which returns non-zero if
752 its argument represents a boolean true value.
753 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
754 check the truth of an expression.
756 Thu Jul 11 12:51:34 EDT 1991
758 language.[ch] Added the predicate structured_type(), which returns
759 non-zero if the argument is a structured type.
760 Added the predicate pointer_type(), which returns non-zero
761 if the argument is a pointer type.
762 eval.c Added the ability to do addition and substraction on
763 pointers and integers. This case simply bypasses the
766 Thu Jul 11 14:41:42 EDT 1991
769 Added the symbol N_DEFD (0x4a) which is a definition
770 module dependency that is used by the GNU Modula-2
771 compiler and the linker. It is not important to GDB,
772 except that [dbx|coff|mips]read.c should ignore these
775 Fri Jul 12 16:07:00 EDT 1991
777 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
778 0 in val_print(). Also added statements to the else part
779 to coerce type (argument to val_print) to a pointer type
780 if it is an "array of unspecified length".
781 valops.c Added the function value_m2_string(), which returns a
782 (value) value which is a constant string, whose type is
783 (ARRAY [0..n] OF CHAR). The length field of the type
784 structure is set to zero, so it will be interpreted as an
785 "array of unspecified length".
786 stack.c Moved the language/frame mismatch check to
787 main.c:execute_command().
788 main.c The working language is recorded each time
789 execute_command() is executed. If working lang has
790 changed during its execution, then the new
791 language/type/range info is printed out for the user. If
792 the working language does not match the language of the
793 frame, a warning is issued.
795 Sat Jul 13 16:16:39 EDT 1991
797 eval.c Moved all the type-checking stuff for operators to
798 language.[ch] language.c. This is so we can keep language-specific
799 stuff (like for what type operators are defined) in
801 language.[ch] Added the function binop_type_check(), which checks to see
802 if its two (value) arguments are type-compatible with its
803 opcode argument. The opcode should represent an operation
804 involving an operator. Also added the macro function
805 unop_type_check, which calls binop_type_check with a
806 NULL second argument.
807 expprint.c Added Modula-2 operators to the op_print_tab, so info
808 expression.h break works correctly. Also added "op_string", which
809 returns the string corresponding to the (enum exp_opcode)
810 opcode that is its argument.
813 Sat Jul 13 18:26:18 EDT 1991
815 coffread.c Added code to record the type of function arguments with
816 each paricular function. Code is very similar to that
818 dbxread.c Moved add_param_to_type() to symtab.c
819 symtab.[ch] Added function add_param_to_type() from dbxread.c
821 *** NOTE: The above additions have not been tested.
823 Mon Jul 15 12:50:47 EDT 1991
825 langauge.[ch] Added the functions type_error and range_error, which work
826 like error() except if the type/range mode is set to
827 *_mode_warn, then they do not do a return_to_top_level(),
828 but merely print a warning.
829 Also changed [set|show]_[type|range]_command() to support
830 the new "warn" feature.
832 Thu Jul 18 17:50:54 EDT 1991
834 mipsread.c Added code to record the type of function arguments with
835 each particular function. Code is very similar to that
838 *** NOTE: The above additions have not been tested.
840 Fri Jul 19 11:19:10 EDT 1991
842 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
843 UMIN_OF_SIZE, which when given a size of a numeric type,
844 return the maximum and minimum value it can hold. UMAX...
845 and UMIN... return the result for unsigned types.
846 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
847 struct types. They call above macros.
848 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
849 avoid a name conlict with the above.
850 c-exp.y Added range checking on numeric constants in
851 parse_number() for completeness.
852 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
853 return 0 if working_lang is not language_c.
855 Thu Aug 8 14:17:22 EDT 1991
859 breakpoint.c Documentation strings of some commands changed to
860 eliminate the references to the C language where
863 Tue Aug 13 15:48:03 EDT 1991
865 m2-exp.y Added qualified identifiers to the grammar. The semantics
866 are slightly different from those of the GDB operator ::
868 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
869 type_exp, where type_exp is any valid type expression.
871 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
872 printcmd.c Modified ptype_command() so it actually parses the input
873 (necessary for type expressions with scope qualifiers).
874 Added the function ptype_eval() which expects an
875 expression composed of one OP_TYPE element.
876 *.[ch] Replaced all occurences of parse_c_expression with
878 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
880 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
882 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)

886 * infrun.c (child_attach): Lint.
887 * solib.c (find_solib): Handle shared libs version 2.
889 Small fixes from David Wood:
891 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
895 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
896 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
898 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
899 chars_per_line is at maximum (user typed `set width 0'). Fix
900 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
902 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
904 * coredep.c: include ptrace.h where necessary.
905 * mipsread.c(parse_lines): fix unsigned char problem that was
906 messing up line numbers on SGI's and possibly other MIPS based
908 * infrun.c (child_create_inferior): use better test to check
909 return val from setpgrp().
910 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
911 for sgi/irix support.
913 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
915 * mipsread.c (parse_symbol): Put non-static procedures
918 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
920 Patch together `text_start' and `text_end' for 29K port.
922 * exec.c (exec_command): If NEED_TEXT_START_END, define the
923 variables and set them based on the exec file.
924 * am29k-tdep.c: declare text_start.
925 * valops.c (call_function_by_hand): declare text_end.
927 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
928 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
929 because machines that do this will also have to know to
930 set NEED_TEXT_START_END. Besides, it was a redundant way to
932 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
933 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
936 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
938 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
940 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
941 Pass MUNCH_DEFINE to munch whenever we run it.
942 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
943 format string; use 0x%x instead.
944 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
945 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
946 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
947 * inflow.c: Handle `short' process group IDs.
948 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
949 and check for ptrace errors.

952 (read_coff_symtab): Use it to find the text [and absolute?] sections.
953 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
954 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
955 Merge target arm case with other "easy" cases. Add target
956 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
957 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
959 * minimon.h, remote-adapt.c, remote-mm.c: Add.
960 * munch: Cope with RT/PC putting fns in data segment.
961 Restore ability to override `nm' by specifying MUNCH_NM.
962 * xconfig/rtbsd, xconfig/ultra3: New host systems.
963 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
964 and remote-adapt. Remove encapsulated coff #define's (the
965 support should go in BFD, and gdb shouldn't know or care).
966 * tconfig/a29k-kern: Same, but for remote kernel debugging.
967 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
968 * tm-29k.h: Update BADMAG (though it should go away).
969 Allow the register definitions to be overridden in another
970 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
971 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
972 DUMMY_SAVE_GR96, for handling kernel calling conventions
973 that use GR64+ rather than GR96+.
974 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
975 remote debugging of Ultra3 kernel. Includes tm-29k.h and
976 overrides various things.
978 * remote-mm.c (mm_attach, mm_wait): Handle attach like
979 child_attach does, making a clean stop in the newly attached
983 * coffread.c: Make coffread independent of any particular
984 variant of COFF. Avoid #include-ing any particular one except
985 internalcoff.h. BFD now passes key values for symbol reading
986 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
987 and the symbol masks and shifts); use them.
988 Remove obsolete end_of_text_addr.
990 * exec.c: Remove unused include files.
992 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
994 * Makefile.in (documentation targets): Pass $(M4).
995 Bugfix from eggert@twinsun.com (Paul Eggert).
997 * stack.c (down_silently_command): Check for stack existence.
999 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1001 * Makefile.in (VERSION): Update to 4.0.3.
1003 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1005 * core.c (core_file_command): Print frame at coredump with
1006 its level number, by calling print_stack_frame.
1007 * frame.h: Add selected_frame_level, print_stack_frame.
1008 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
1009 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
1010 Change print_sel_frame and print_selected_frame callers to
1013 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
1014 * symfile.c (free_named_symtabs): Ditto.
1015 * main.c (main): wrap_here needs an arg.
1016 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
1017 (solib_add): Avoid noise.
1018 (solib_create_inferior_hook): Lint.
1019 (sharedlibrary_command): Move dont_repeat to here.
1020 * utils.c (error): Call wrap_here to force buffered output.
1022 Small patches from Peter Schauer:
1024 * coffread.c (start_symtab): Free any existing line_vector before
1026 (read_coff_symtab): Ditto for type_vector.
1028 * source.c (lines_to_list): New variable, replacing function.
1029 (all uses): Use as variable.
1030 (_initialize_source): Add 'set listsize' and 'show listsize'.
1031 * utils.c (lines_to_list): Remove function.
1032 * stack.c (print_frame_info): Use as variable.
1033 * defs.h (lines_to_list): Remove declaration.
1035 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1037 * breakpoint.c (insert_breakpoints): Restore warning about
1038 the program might be running in another process, but only for
1039 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
1040 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
1042 * utils.c (error): if error_pre_print is set, print the string
1044 * main.c (main, print_gnu_advertisement, print_gdb_version):
1045 Reformat legalese so it always prints, but acts as an "I'm here"
1046 message while symbols are being read. If any errors occur,
1047 print a few newlines to set off the message and start it at the
1048 left margin. Remove mention of "help" command, and don't yak
1049 about symbol reading.
1050 (catch_errors): Error string is now printed first in case of
1052 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
1053 suggest the "help" command.
1055 * Makefile.in (VERSION): Set to 4.0.2.
1057 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
1059 * .gdbinit: Remove useless "rr" command. Set complaints
1060 to 1 for people debugging gdb.
1062 * breakpoint.c, remote-vx.c: Reword strings printed by
1063 catch_errors callers.
1065 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
1067 * WHATS.NEW: "history write -> history save". Doc "write on/off".
1068 (Fix from kenc@viewlogic.com.)
1070 Fix some infrastructure to be able to cope with host and target
1071 machines with different sized basic types (ints, ptrs, etc).
1072 (Idea from pierre@la.tce.com (Pierre Willard).)
1074 * values.c (value_from_longest): Rename from value_from_long.
1075 Handle pointer types as well as integers, so that targets with
1076 different pointer sizes from the host can be accomodated.
1077 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
1078 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
1079 uses of value_from_long to value_from_longest.
1080 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
1081 the correct pointer type to value_from_long{est}.
1083 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
1085 * remote-vx.c: Remove obsolete code for calling functions via
1086 vxworks kludge interface (it referenced value_from_long).
1088 * valops.c (value_string): Find malloc with lookup_misc_func, not
1091 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1093 Make writing to files work properly. (Fixes to BFD are also needed.)
1095 * core.c (core_open): Open file ourselves, read or r/w, depending on
1096 write_files. Use bfd_fdopenr.
1097 * gdbcore.h (write_files): New variable.
1098 * exec.c (write_files): Define variable, add set&show for it.
1099 (exec_file_command): Use write_files to open for read or r/write.
1101 Make shared library reading happen automatically. These changes
1102 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
1104 * inferior.h (stop_soon_quietly): Add to exported variables.
1105 * infrun.c (child_create_inferior): call solib hook, if defined.
1106 (child_attach): call solib hook, if defined.
1107 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
1108 (find_solib): Use lookup_misc_func rather than hand-rolled.
1109 (symbol_add_stub): New stub for catch_errors.
1110 (solib_add): Avoid output if !from_tty. Catch errors rather
1111 than just calling symbol_file_add and bombing.
1112 (solib_create_inferior_hook): Interface with the target process
1113 to let it read and alloc shared libs, then figure out what it did.
1115 * core.c (validate_files): Fix typo, soften warning.
1116 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
1118 * utils.c (fputs_demangled): Avoid duplicate printing if
1119 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
1121 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
1122 (Fix from pierre@la.tce.com (Pierre Willard).)
1124 * main.c (catch_errors): Change argument to a char * from an int,
1125 since a char * can point to a struct full of glop, but an int
1126 is not guaranteed to be able to hold a pointer.
1127 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
1128 breakpoint_re_set_one, breakpoint_re_set): Adapt.
1129 * core.c (core_open, solib_add_stub): Adapt.
1130 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
1132 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1134 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
1135 by adding .NOEXPORT target.
1137 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1141 * Makefile.in (VERSION): Roll to 4.0.
1142 (gdb.tar.Z): Make refcard.ps as well, for shipment.
1144 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1146 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
1149 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
1152 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
1154 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
1155 reflect above name change
1157 * WHATS.NEW: correct pointer to refcard.
1159 * doc/gdb.texinfo: update New Features, Installing
1161 * doc/gdbint.texinfo: add short description of configure +template
1163 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1165 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
1167 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
1169 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
1170 tar file, add dependencies for referenced doc files.
1172 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
1174 * coffread.c, symfile.c, stack.c: saberized.
1176 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1178 * doc/refcard.tex: permuted Essential Commands sec
1180 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
1182 set/show symbol-reloading
1183 default set complaints 0
1185 RET-repeat disabled after prompted long displays
1186 processID (attach) interpretation of 2nd GDB cmdline arg
1188 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
1190 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
1191 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
1192 breakpoint.c, main.c: lint.
1194 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1196 Install new configuration scheme for GDB and friends.
1198 * config.sub: Translate ordinary names to three-part names.
1199 * configure: Use three-part names internally.
1200 * configure.in: Translate three-part names to filenames.
1202 * README, WHATS.NEW: Update for gdb-4.0.
1203 * Makefile.in: Roll VERSION to 3.99.
1205 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
1207 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
1208 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
1209 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
1210 to single structures rather than arrays; when passing
1211 their address, use &. This avoids trouble with bdead compilers.
1212 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
1213 instead. This avoids portability headaches.
1214 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
1216 * source.c (open_source_file): Avoid ANSI const bdeath by
1217 skipping declaration and then casting result value.
1218 * tm-hp300bsd.h: Clarify comment.
1219 * utils.c (strstr): Result is const char *; ANSI bdeath.
1220 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
1221 since system include file defines it differently from "defs.h",
1222 though the two are equivalent for our purposes.
1223 * tconfig/hp300bsd: Add m68k-tdep.o.
1225 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1227 * tconfig/sun*4: Remove warnings about system assembler.
1229 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1231 * mcheck.c: Avoid warning about undeclared abort fn.
1232 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
1233 it causes recursive calls to error() when used in cleanups.
1234 To do so requires that we make it a function, so we do.
1235 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
1236 * utils.c (do_cleanups): Remove the current cleanup from the
1237 chain *before* calling it, in case error() is called from it.
1238 The result won't be pretty, but won't be an infinite loop either.
1240 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
1242 * dbxread.c (read_struct_type): Grok anon structs for C++.
1243 (vb_name, vptr_name): Null terminate these strings.
1245 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1247 Minor bug fixes from BSD Net2 gdb:
1249 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
1250 returns 0, there is no previous frame.
1251 * breakpoint.c (commands_command): If !from_tty, don't call
1252 input_from_terminal_p().
1253 * dbxread.c (record_misc_function): Speed up slightly.
1254 (compare_psymbols): Ditto.
1255 * infcmd.c (do_registers_info): Take a second argument to
1256 determine whether to print float registers. "info registers"
1257 does not do so anymore. "info all-registers" does, now.
1258 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
1260 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
1261 * inflow.c (initialize_inflow): Set tflags_ours correctly.
1265 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
1266 executing_breakpoint_commands if we are interrupted by error.
1267 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
1268 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
1269 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
1270 catch_errors() so we can setup the frame regardless of whether
1271 the shared libs work.
1272 * ieee-float.c (double_to_ieee_extended): Get exponent from
1273 right place in little-endian systems. From John Carey.
1275 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1277 * main.c: Remove unused terminating_signals and catch_termination().
1278 (long_options): Terminate with a zero element.
1279 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
1280 (gdb_readline): Make call-compatible with readline.
1281 (init_signals): Improve comments re vfork vs. signal.
1283 * utils.c (prompt_for_continue): Use new gdb_readline().
1284 If we prompt for continuation, we don't let CR repeat the previous
1285 command, once we get back to a prompt. It's too easy to keep
1286 hitting CR, expecting "--more--" prompts, and have some long
1287 command start repeating on you.
1289 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1291 * blockframe.c (frameless_look_for_prologue): Speed up by
1292 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
1293 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
1294 Define two variants, one faster.
1295 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
1296 and return zero, rather than giving an error.
1297 (setup_arbitrary_frame): Initialize the PC in the new frame.
1298 (skip_prologue): Add a second arg saying whether we're just
1299 checking for a frameless function or not.
1301 * core.c (core_open, core_close, core_xfer_memory): Move
1302 section table pointers and bfd* into the target_ops.
1303 (core_open): Allow errors in shared lib reading, etc.
1304 (core_files_info): Describe shared library sections.
1306 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
1307 exec_files_info, set_section_command): Move section table
1308 pointers and bfd* into the target_ops.
1309 (add_to_section_table): Add BFD to section table.
1311 * target.c (target_xfer_memory, target_info): Pass target to
1312 xfer_memory and target_info functions.
1315 * gdbcore.h: Move struct section_table.
1316 * target.h: New home of struct section_table.
1318 * solib.c (solib_add): New argument is the target_ops whose
1319 section list is to be added to, if any. Reallocate the
1320 sections in that target to add any that come from shared libs.
1321 (throughout) so_sections renamed to sections.
1322 (solib_xfer_memory): Deleted.
1323 * tm-sunos.h (SOLIB_ADD): Add target argument.
1324 (SOLIB_XFER_MEMORY): Delete.
1326 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1327 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
1328 from target_ops. It's the same on all targets. Add two section
1329 pointers to target_ops.
1331 * stack.c (find_relative_frame): Dump ancient algorithm for
1332 "down", just use handy "next" pointers.
1333 (frame_command): Don't error if there is no stack; let user
1336 * inflow.c (new_tty_prefork, new_tty): New prefork routine
1337 modifies static state in the parent process; new_tty itself
1338 runs in the child and modifies the child's file descriptors
1339 to match the saved static state.
1340 * infrun.c (child_create_inferior): Call new_tty_prefork,
1343 * infptrace.c (child_xfer_memory): Add ignored target arg.
1344 * remote-eb.c (eb_xfer_inferior_memory): ''
1345 * remote-nindy.c (nindy_xfer_inferior_memory): ''
1346 * remote-vx.c (vx_xfer_memory): ''
1347 * remote.c (remote_xfer_memory): ''. Rename from
1348 remote_xfer_inferior_memory.
1350 * main.c (main): Only try to attach "corefile" argument if
1351 it starts with a digit.
1353 * symfile.c (symbol_reloading): New "set/show" variable.
1354 (symbol_file_add): Shorten message about symbol reading.
1355 (add_symbol_file_command): Merge with add_syms_addr_command,
1356 since this should work on all targets now.
1357 (stop_whining): Default to zero, to shut up complaints
1358 about bad symbol tables on many systems.
1359 (free_named_symtabs): Just exit unless symbol_reloading.
1361 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
1362 and add comment explaining shared library screw.
1364 * source.c: #if defined => #ifdef.
1366 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1368 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
1370 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1372 * doc/rdl-apps.texinfo: provide default readline-appendix finder
1373 (doc/Makefile knows how to make one for local config)
1375 * Makefile.in: use doc/Makefile for doc targets
1377 * doc/Makefile: GDB documentation now has its own Makefile
1378 doc/refcard.tex: renamed from "gdbrc.tex"
1379 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
1380 doc/gdbint.texinfo: add markup in "Cleanups" chapter
1383 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1385 * values.c (baseclass_addr): When reading target memory, use the
1386 length of the basetype, not the upper type. We've only malloc'd
1387 enough space for the basetype, leading to errors in free().
1389 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
1390 ends up as a function specially, since we know the actual type of
1391 the pointed-to address. This (somewhat) fixes display of
1392 expressions that include misc_function_vector names. Try `cond 1
1393 !strcmp("a","b")' then `i b'.
1395 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
1396 The child can be proceeded from inside wait_for_inferior in
1397 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
1398 getting skipped in that case.
1400 * expprint.c (print_subexp): Use filtered output, since the
1401 subroutines we call use it, otherwise the output is horribly
1402 mangled, since output of wrappable stuff comes out late.
1404 * Makefile.in: Bump VERSION to 3.98.1
1406 * infrun.c (child_create_process): Use execlp to find the
1407 shell to exec our target program. This requires some fiddling
1408 with `environ' since there is no execlpe().
1410 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1412 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
1413 Minor rearrangement of refcard permits two new make targets--
1414 gdbrc.dvi DVI output for refcard, using CM fonts
1415 gdbrc.ps PostScript refcard, using PS fonts
1417 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1421 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
1422 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
1424 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1426 * doc/gdb.texinfo: last changes for release.
1427 Minor typo and formatting fixes; incorporated most fixes remaining from
1428 filed mail commenting on earlier drafts.
1430 Added warnings: pipes don't work in run command;
1431 conditions are converse of assertions;
1432 step over fn without debug info goes to next fn;
1433 vars may have "wrong" values near fn entrance, exit
1435 Added example from Kingston on printing repeated nonadjacent values
1437 Added explicit mention that in Emacs gdb mode C-c and C-z are like
1438 shell mode for signals
1440 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
1441 doesn't sound so much like its parent "Stopping and Continuing"; also
1442 moved entries on continue to top of section, so they don't get lost.
1444 Improved installation directions in appendix, added manual formatting
1447 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1449 * configure.in: Remove xm.h and tm.h even if we aren't linking
1450 new ones, so "./configure sun4; ./configure none" does the right
1451 thing. Assume that alldeps.mak and depend are already built in
1452 srcdir, and avoid running "make" (particularly "make depend",
1453 which involves "gcc") from inside configure. Build Makefile
1454 directly rather than building Makefile.conf first.
1455 * configure: Regenerate with above changes.
1456 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
1457 to 3.98. Revise gdb.tar.Z procedure to produce a file
1458 called gdb-$(VERSION).tar.Z but which unpacks into a
1459 directory called "gdb". Move non-source files out of
1460 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
1461 (depend): Don't try to do "gcc expread.y".
1462 (expread.o): Update dependencies by hand.
1464 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1467 Fixed a variety of small typos that prevented info from formatting
1468 cleanly; altered too-long heading for GPL Appendix, as discussed
1469 w/RMS; Changed date on cover to July 91.
1471 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1474 (1) Applied some fixes due to comments from Larry Breed (easier ones
1475 through chapsec 5.2)
1476 (2) Eliminated use of @footnote---had my doubts about it anyways, and
1477 it's broken in latest texinfo
1478 (3) Introduced *some* use of [] for optional arguments, where
1479 explanation is not simpler by listing cmd w arg and cmd w/out arg
1480 separately. Still not using @deffn.
1481 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
1482 couple of headings are too long. Need patches to texinfo or revision
1485 * Partial update to README (which still needs work for this
1486 release!): (1) use of configure corrected for new script,
1487 (2) "make gdb.dvi" and "make gdb.info" mentioned.
1489 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
1491 * symtab.c (lookup_symbol): Don't complain right off about
1492 no debug symbols; use the misc function vector first.
1493 (list_symbols): Use misc function vector to find symbols
1494 that don't have debug info, and print them.
1495 (find_pc_symtab): Temporarily avoid fatal() when psymtab
1496 PC range doesn't match symtab PC range, as it does on the
1497 MIPS because our symtab reading isn't perfect.
1499 * dbxread.c (dbx_symfile_read): Make warning about
1500 "no debug symbols" slightly nicer.
1502 * source.c (select_source_symtab): If "main" symbol exists,
1503 but decode_line_spec can't find line info, don't just return
1504 a zero; try other source symtabs or give an error.
1506 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
1507 their low addresses first, then rip through fixing high addrs.
1509 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
1510 <runene@ifi.uio.no>.
1511 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
1513 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1515 * Minor, mostly mechanical, cleanup of doc subdir for clean
1516 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
1517 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
1519 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
1521 Mostly MIPS and general symbol-reading fixups.
1523 * doc/gdbint.texinfo: Add documentation on symbol-reading
1526 * mipsread.c: Remove kludges around #include "ecoff.h".
1527 Remove redefinitions of a_magic, etc, no longer used.
1528 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
1529 Fix global overview comments to match symfile.c protocol.
1530 (mipscoff_new_init): Eliminate cur_hdr if we have one.
1531 (mipscoff_symfile_read): Eliminate unused code. Avoid
1532 sorting all the symtabs, when all we have read here is psymtabs.
1533 The symtabs are sorted as they are created anyway. Tell
1534 condense_misc_bunches whether we're mainline.
1535 (psymtab_to_symtab_1): Pass filename when recursing, to make
1536 stack trace more informative.
1537 (parse_partial_symbols): Assume cur_hdr as argument.
1538 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
1539 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
1540 the TYPE_NAME of char *, since that's done in symfile.c.
1541 (free_numargs, parse_symbol, add_symbol, add_block,
1542 shrink_linetable): Declare these fns void.
1543 (upgrade_type): Convert tree of if's to switch. Clean up
1544 bogus "off == 0" handling with a complaint. Avoid setting
1545 field bitpos and bitsize of array with lower and upper bounds.
1546 Check specified bitsize of elements against their actual type's
1547 bitsize, and complain if different. Complain about unknown
1549 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
1550 (psymtab_to_symtab_1): Print names of subsidiary files that
1551 are being read in. FIXME, we read far too many files. This code
1552 is not the problem, the problem is in parse_fdr where the psymtabs
1554 (cross_ref): Result should indicate that we used one aux entry
1555 normally, or two if we encountered a "next" entry. This used
1556 to leave the caller pointing at the wrong aux entry.
1557 (add_symbol): If overflowed cur_block, reallocate it larger,
1558 chase all pointers to it, and complain(), rather than clobber memory.
1559 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
1560 (new_field): Only allocate one field initially, not two.
1561 Pull ++ out of macro argument. Simplify.
1562 (_initialize_mipsread): Avoid initialization of importd
1563 global_psymbols and static_psymbols.
1565 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
1566 to properly set pst->symtab; avoid searching for it.
1567 (symfile_fns): Improve comments, add a FIXME.
1568 * dbxread.c: Update comments to reflect symfile protocol.
1569 (read_ofile_symtab, end_symtab): Return the symtab.
1570 (psymtab_to_symtab_1): Set pst->symtab.
1572 * coffread.c (coff_symfile_read): tell condense_misc_bunches
1573 whether we're mainline.
1575 * symfile.h (sym_fns): Remove unused sym_discard member.
1576 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
1578 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
1579 the environment variable is not.
1580 * infcmd.c (finish_command): Use filtered printfs.
1581 * cplus-dem.c: Add struct tags to a few unnamed structs.
1582 * valops.c (value_coerce_array): Improve comments.
1583 * valprint.c (type_print_varspec_suffix): Print array size only
1584 if greater than zero.
1585 * m88k-tdep.c: Shift some lines left by one space, that had
1586 apparently been trashed at some point.
1587 * TODO: More things to do, a few got done.
1589 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1591 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
1592 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
1594 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
1595 * expread.y, findvar.c, symmisc.c: Ditto.
1596 * printcmd.c (address_info): Update printed forms of LOC_
1597 symbols. Elim LOC_EXTERNAL.
1598 (print_frame_args): Keep track of param stack offsets before
1599 re-looking up to find the local register param is kept in.
1601 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
1602 Further integration of mipsread into gdb. Eliminate unused
1603 routines, duplicate declarations. Handle static symbols in
1604 psymtabs as well as external symbols. When reading symtabs,
1605 insert symbols into the correct block (global, static, or a local
1607 (read_mips_symtab, parse_partial_symbols): Don't pass useless
1609 (mipscoff_symfile_read): Don't call select_source_symtab.
1610 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
1611 rather than SYMBOL_VALUE.
1612 (parse_external): Comment clobbering of top_stack.
1613 (parse_partial_symbols): Update comments. Allocate and parse
1614 static symbols as well as external symbols. FIXME, enum values
1615 are not handled in this pass, but should be. Inline new_psymbol.
1616 Use SYMBOL_VALUE_ADDRESS.
1617 (psymtab_to_symtab_1): Read symbols into global static block
1618 by default (until enter some function's local block context).
1619 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
1620 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
1622 * source.c (select_source_symtab): Select a source symtab
1623 from either the symtabs or, failing that, the psymtabs.
1624 (list_command): Update error message.
1625 (forward_search_command, reverse_search_command): Use getc, not
1626 fgetc, for speed. FIXME, add comment about buffers that die if
1627 overrun by long line.
1629 * values.c (unpack_field_as_long, modify_field): Avoid shifting
1630 by an entire word, which is not portable, if we have a 32-bit
1631 field. (Code in dbxread.c already turns such bitfields, if
1632 aligned, into ordinary ints, but fixing this will help for other
1633 symbol formats and for future changes.)
1634 * core.c (core_open): Handle ANSI const brain death.
1635 * utils.c (vprintf): Fix varargs typo.
1637 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1639 * findvar.c (find_var_value): Handle &function better.
1640 * TODO: Document work needed on &fn and &array.
1641 * printcmd.c (print_address_symbolic): New arg is the prefix
1642 to print if a name is printed.
1643 (print_address_demangle): Honor "set print address" now.
1644 Use new arg above to improve spacing of output.
1645 * valprint.c (val_print): When printing function pointers,
1646 print symbolic form too.
1647 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
1649 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1651 * core.c (memory_error): Reword error msg to mislead less.
1653 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
1655 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
1656 parse_partial_symbols): Use newer BFD internals (external_filehdr
1657 and external_aouthdr), byte-swap the fields that we care about
1658 before using them, and make the file header data local to
1659 read_the_mips_symtab rather than global.
1661 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
1663 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
1664 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
1666 * main.c (command_line_input): Flush stdout and stderr
1667 before every call to readline. This reportedly fixes a bug
1668 that comes up in Sys V running emacs-gdb and/or xxgdb,
1669 when stdin/out are pipes or sockets.
1671 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1673 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
1674 Avoid declaring Makefile dependencies, because GNU Make stupidly
1675 tries to update it if we do.
1677 * coffread.c: Revise for minor changes to bfd internal coff
1680 * configure: If -template= is given a relative path, make it
1681 absolute before recurring in subdirectories.
1683 * configure, configure.in, Makefile.in: Install "configure" script
1684 as replacement for config.gdb.
1685 * config.gdb, Makefile.dist, Makefile.sdir: Remove
1686 * README: Update for configure, mostly. FIXME.
1688 * Add dec3100 as equivalent to littlemips. Indicate in all host &
1689 target config files that they are for the host. When the lines
1690 get copied into the Makefile, this makes it more obvious what's
1693 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1695 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
1696 tabs, which end up in the disassembler output inadvertently.
1698 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1700 Make it compile cleanly in an ANSI GCC2 environment.
1702 * blockframe.c: <stdio.h>
1703 * cplus-dem.c: free takes a void *, ifdef __STDC__
1704 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
1706 * defs.h (alloca): Avoid doing anything if alloca already def'd.
1707 * stddef.h, stdlib.h: Remove these files.
1708 * symtab.c: Avoid declaring qsort, close.
1709 * symfile.c: Avoid declaring close.
1710 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
1711 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
1713 Assorted other changes.
1714 * dbxread.c: include "libaout.h", not "liba.out.h".
1715 * printcmd.c (print_frame_args): Set recurse properly for
1716 indentation of struct and array parameters.
1717 * valops.c (value_cast): Allow cast to void.
1718 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
1719 single_step() in a target-independent fashion.
1720 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
1721 set up to be ready to continue. This makes us target independent.
1722 * infptrace.c (child_resume): Remove call to single_step; now
1723 can single step a SPARC target of any kind.
1725 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1727 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
1728 docn into separate sections---basically chapters, plus two loose
1729 pieces that can be configured to go in different places. This
1730 allows GNU m4 to preprocess the manual without coredumping.
1732 * Makefile.dist: tell TeX where to find texinfo.
1734 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1736 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
1737 the new target "rdl-apps.texinfo" which captures the Makefile
1738 variable that records where to find the Readline libraries.
1740 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
1742 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
1743 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
1744 * defs.h (const, volatile): Only define if not already defined.
1745 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
1747 * README: Update for release 3.95.
1748 * config.gdb: Don't create readline dir in subdir builds.
1749 * main.c: Include with "..." form for non-system include files,
1750 so "gcc -MM" for "make depend" works.
1751 Include readline files with "...h" rather than <readline/...h>.
1752 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
1754 * coffread.c: Undo minor damage done by Rich Pixley. Use
1755 different internal and external representations of COFF
1756 data structures. Use new BFD routines for swapping them in and
1758 * symfile.c (free_named_symtabs): Avoid freeing file names that
1759 are null or empty. Old i960 tools seem to produce files that
1760 claim to have empty names, causing each successive file read
1761 to blow away the previous one.
1762 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
1763 Move deferred_stores to top of file, but don't separate its
1764 #define's from its variable. Add commentary.
1765 * Makefile.dist: Fix Rich damage; undo "configure" changes in
1766 favor of keeping the (working) config.gdb. Move readline
1769 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
1771 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
1773 * infptrace.c (fetch_registers): no result, since now void.
1774 * tconfig/news: target depends on m68k-tdep too.
1776 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1778 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
1781 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
1782 applied various small fixes due to or inspired by RMS comments
1784 * doc/gdb.texinfo: finished using all RMS comments, save those for
1785 appendices on readline and cmd history (which are in other source
1788 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1790 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
1791 chapter 9; (2) documented 'break' command's menu mode for
1792 overloaded names, in response to hgs problem report C++ p-31
1794 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1796 * doc/gdb.texinfo: (1) better introductory example; (2) more
1797 consistent use of @code, @samp, @file, @kbd throughout; small
1798 cleanups to first three nodes; (3) new "Contributors" node;
1799 (4) Appendix, Renamed Commands; (5) divert specialized startup
1800 instructions to "Targets" chapter for generic manuals, while
1801 leaving them up front for manuals specific to specialized
1802 environments; (6) apply fixes from RMS comments through chapter 4.
1804 * pretex.m4: modify explanatory text slightly (and redefine
1805 "regexp") to keep GNU m4 from complaining. (It still crashes
1806 later, but one step at a time...)
1808 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
1810 * readline/readline.c (update_line): Avoid dereferencing a pointer
1811 before comparing it to its bounds. Saber caught this.
1812 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
1813 and only set PC if tgetstr returned non-null. Saber caught this.
1815 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1817 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
1818 stuff for config manual) here where it counts; updated
1819 to use new subdir structure (gdb/doc/).
1821 * Makefile: generated from above via
1825 * gdbint.texinfo: added instructions on generating gdb.info* files
1826 locally for release. These are ordinary info
1827 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
1828 Makefile)---but due to use of texinfo 2, can't count on makeinfo
1829 to generate these, so we distribute them already formatted.
1831 * gdb.texinfo: included full Info node and menu crud (as generated
1832 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
1834 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
1835 put in comments-for-future gdb.info target (one day makeinfo will
1838 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1840 * gdb.texinfo: Updated to include new or old undocumented
1841 commands, at least the following (perhaps some others I forgot to
1842 record): info f, info float, info path, info program, info s, info
1843 set, info source, info terminal, info types, info user, set/show
1845 Also covered all recent GDB command renames for v4.
1847 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1849 * mipsread.c: Rather than keeping count of how many symtabs
1850 and psymtabs we have, for sorting purposes, count them when
1851 we need to sort. This fixes bug in rereading of symbol tables.
1853 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1855 * infcmd.c: renamed "info path" to "show paths"
1856 * gdbrc.tex: documented above.
1858 Wed May 8 04:51:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1860 * remote.c: Fix comments.
1861 * utils.c (error): Force out any pending wrap output.
1863 Sat May 4 11:11:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1865 * Makefile.dist: Roll VERSION to 3.95.
1866 Fix up "saber_gdb" to work again.
1867 * saber.suppress: Update.
1869 * coffread.c, exec.c, infptrace.c, inftarg.c, remote.c, solib.c,
1870 symtab.h, target.c, target.h: Lint.
1871 * core.c: setup and select frame after reading shared libs,
1872 else reading shared libs will clobber them. Lint.
1873 * utils.c (error): Force out any buffered wrap text.
1875 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1877 * remote.c: Remove decls of memory_insert_breakpoint
1878 and memory_remove_breakpoint, no longer used. (Suggestion of
1881 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
1882 to make it easier to interface to "configure"'d libraries.
1884 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
1886 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
1887 aliases for set/show print.
1889 Thu May 2 11:22:02 1991 Jim Kingdon (kingdon at cygint.cygnus.com)

1929 * {x,t}config/m88k ({X,T}DEPFILES): Add missing files.
1931 * mtrace.c: Don't typedef things like size_t, just #define them.
1933 * coffread.c [TDESC]: #if 0 out references to coffsyn.
1935 * symtab.h (struct symtab): Include EXTRA_SYMTAB_INFO.
1936 tm-88k.h: Define EXTRA_SYMTAB_INFO.
1938 * coffread.c [TDESC]: Include "tdesc.h" and make tdesc_handle
1939 dc_dcontext_t not int.
1941 * coffread.c [TDESC]: Use system include files not <intel-coff.h>.
1943 * coffread.c [TDESC]: Move setting of debug_info from
1944 coff_symfile_read to find_linenos and make it work with BFD.
1946 * cplus-dem.c [__STDC__]: Make x{m,re}alloc return void*.
1948 * signame.c: Cast const char* to char* when assigning to sys_siglist.
1950 * utils.c (strsave): Make arg const char* not char*.
1952 * infrun.c (wait_for_inferior) [SHIFT_INSN_REGS]: Use
1953 bpstat_explains_signal (stop_bpstat) not stop_breakpoint.
1955 * tm-88k.h (START_INFERIOR_HOOK): Make tdesc_handle a dc_handle_t.

1976 * infptrace.c (PT_WRITE_D, PT_READ_D): Use correct values.
1977 (This still doesn't seem to make MIPS bkpts work.)
1978 * mipsread.c: Remove dup "Reading symbol data..." msg.
1979 (symbol_file_command, add_file_command): Remove, obsol.
1980 * printcmd.c (ptype_command): Say "an enum" rather than "a enum".
1981 Wrap output appropriately.
1982 * stack.c (locals_info, catch_info, args_info): Check
1983 selected_frame rather than target_has_stack or coredumping.
1984 * valprint.c (type_print_varspec_suffix): Wrap "ptype" output of
1985 enums appropriately.

2452 (symbol_file_command): Don't reference symfile_fns if it's zero.
2454 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
2455 defines for the blocks of a blockvector that contain global and
2456 file-static symbols and the first of the smaller scope contours.
2457 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
2458 decode_line_1, make_symbol_completion_list): Use the above.
2459 * coffread.c (end_symtab, patch_opaque_types): Ditto.
2460 * dbxread.c (end_symtab): Ditto.
2461 * expread.y (block): Ditto.
2462 * mipsread.c (throughout): Ditto.
2463 * symmisc.c (free_named_symtabs): Ditto.
2465 * symtab.c (list_symbols): Process the first symbol of the
2466 static psymbols list.
2467 (types_info): Restore this function from its untimely #if 0.
2468 It's not perfect, but it is better than nothing.
2469 (_initialize_symtab): Restore "info types".
2471 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2473 * m68k-stub.c: Remote stub for 680x0's, created from
2474 rem-m68k.shar (which is removed).
2475 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
2476 Remove RCS log stuff now that we use CVS and it blows our diffs.
2478 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2480 * symmisc.c (free_named_symtab): Make it work, in its current
2481 kludgy fashion. Change result to indicate if we blew away bkpts.
2482 * dbxread.c (end_symtab): Accumulate result from
2483 free_named_symtab and print warning if we blew user's state.
2484 * symfile.h: free_named_symtab now returns an int.
2486 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
2488 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
2489 is the first symbol read, even if not mainline.
2490 (dbx_psymtab_to_symtab): symfile might be zero, cope.
2491 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
2492 (set_section_command): New command ("section xxx yyy" -- should
2493 be renamed to "set section xxx yyy" FIXME) which sets the
2494 base address of a section of the exec file, overriding the
2495 virtual address that BFD reports.
2497 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2499 * exec.c: Add add_syms_addr_command to exec_ops, so you can
2500 load symbols at any address while examining an exec file.
2502 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
2504 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
2505 for printing the float info is host-dependent, not
2506 target-dependent. FIXME.
2507 * i386-pinsn.c: Move #includes to top, remove useless ones.
2508 * i386-tdep.c: Don't bother including <.../reg.h> since we
2509 don't use it (and it doesn't exist on host systems).
2511 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
2512 Convert negative numbers properly.
2513 (ieee_test): Make numbers really random; fix format arg.
2515 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
2516 * core.c (core_detach): Unpush core_ops, which might not be on
2517 top. We used to just pop the top, which broke things. Don't
2518 need dont_repeat() any more.
2519 (core_file_command): Psst! Don't repeat it.
2520 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
2521 * expprint.c (print_subexp): Avoid switch fallthru on
2522 BINOP_ASSIGN_MODIFY, so we can print += and such.
2523 * frame.h: Fix typo.
2524 * inflow.c (kill_command): After killing inferior, print our
2525 current frame in the core file, if we have one.
2526 (generic_mourn_inferior): When inferior dies, either select
2527 the current frame (in the new target, e.g. core file), or
2528 set both the current and selected frames to NULL.
2530 Changes from Peter Schauer.
2532 * infptrace.c: Avoid <sys/ptrace.h> on USG.
2534 * Make all file names fit in 14 characters (sigh and damn!):
2535 mv hp300hpux-xdep.c hp300ux-xdep.c
2536 mv symmetry-xdep.c symm-xdep.c
2537 mv symmetry-tdep.c symm-tdep.c
2538 mv convex-opcode.h convx-opcode.h
2539 mv tm-vxworks960.h tm-vx960.h
2540 mv tm-vxworks68.h tm-vx68.h
2541 mv Makefile.srcdir Makefile.sdir
2542 mv gdb-int.texinfo gdbint.texinfo
2543 mv remote-sa.m68k.shar rem-m68k.shar
2544 mv remote-multi.shar rem-multi.shar
2545 * Makefile.dist, README, config.gdb, convex-pinsn.c,
2546 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
2547 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
2550 * command.c (user_info_1, user_info): New command for listing
2551 the user-defined commands.
2553 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
2555 * dbxread.c (really_free_pendings): Clear file_symbols
2556 and global_symbols after freeing them; otherwise, running
2557 this function twice (if it appears twice on the cleanup
2558 chain), we try to free things twice.
2560 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
2561 based on text_addr (the address of text in core), not on addr (the
2562 offset between text in the .o file and in core). This change
2563 is from Peter Schauer.
2565 * main.c: Define ALL_CLEANUPS as a cast of zero.
2566 (return_to_top_level): Use it.
2567 (main): Do all cleanups after each command run as part
2568 of the gdb startup sequence. Also do all cleanups before
2569 entering the command loop, and every time we exit the command
2570 loop and reenter. Before, the cleanups from the startup sequence
2571 were being left undone until the first error!
2572 (command_loop): Rename do_nothing cleanup to command_loop_marker
2573 so we can see it easily when examining the cleanup chain.
2574 (init_signals): Add another do_nothing for signal handling.
2575 (quit_command): Only try to kill target if it has execution.
2576 Problems in the target stack got us into a state where
2577 inferior_pid was nonzero but none of the targets had execution.
2578 In this state you couldn't exit gdb.
2580 * dbxread.c: Two changes from Peter Schauer.
2581 (echo_command): Fflush output after an echo command.
2582 (show_history): Pass all args to cmd_show_list.
2584 * utils.c (init_malloc): Call mtrace to turn on tracing
2585 if the environment variable MALLOC_TRACE is set to a file name.
2586 * mtrace.c: Add source file which provides a log of every malloc,
2587 free, and realloc to a trace file.
2588 * mtrace.awk: Add source file which analyzes the trace file.
2589 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
2590 (VERSION): Roll to 3.94.3.
2592 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
2593 (check_duplicates): Don't bother with watchpoints.
2594 (set_raw_breakpoint): Comment about danger of this routine.
2595 (watch_command): Parse and eval all args before calling
2598 * solib.c (find_solib): Avoid error in referencing memory to
2599 see if any more shared libraries have been added. This is
2600 particularly useful if the target has terminated. Bug reported
2603 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
2604 in bringing up 3.94.2 on the Sun-3.
2606 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
2607 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
2608 expression (in scope) before reenabling watchpoint.
2609 * signame.c (init_sigs): Add missing declaration of i, fix
2610 sys_siglist declaration.
2611 * source.c (list_command): Fixed range computation to use
2613 * stack.c (backtrace_command): Do not allow command if target has
2614 no stack, print informative error message.
2615 * target.c (target_command): Do not write into command line
2616 because this fails if the target command is used in a user defined
2617 command. [This change was enhanced by gnu to support any-
2618 unique-prefix matching on target names.]
2619 * valops.c (value_struct_elt): Avoid infinite loop on an
2620 erroneous attempt to print the member of function (try p main.p).
2622 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
2624 * expread.y (name_no_typename): Avoid reduce/reduce errors
2625 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
2626 Since the GDB parser really doesn't use name_no_typename in a
2627 name-only context, the parser can't tell the diff between
2628 names and numbers here. Avoid allowing a name_no_typename
2629 to be a NAME_OR_*INT to resolve the conflict.
2631 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2633 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
2635 * valprint.c (val_print_fields): bitfield printing didn't handle
2636 byte order. Indirect through a few more fns to cope.
2638 * values.c (modify_field): also cope with byte order.
2640 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2642 Cleanup for release 3.94.2:
2644 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
2645 include files. Roll version to 3.94.2.
2647 * coffread.c (init_stringtab): Read length into unsigned char
2648 array before swapping; don't assume 32-bit longs.
2650 * target.c (target_info): Don't bother with get_sym_file, just use
2651 the symfile global variable.
2652 * symtab.h, symfile.c (get_sym_file): Delete it.
2654 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
2655 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
2656 (read_type): Replace one more error() with complain().
2658 * mipsread.c (parse_partial_symbols): Replace printf with complain.
2660 * i960-tdep.c: Fix copyright attribution.
2662 * config.gdb: Quote all backquotes in doublequotes. You can
2663 quote me on that. BSD 4.4 shell found this one.
2665 * infptrace.c (throughout): The third argument to ptrace is an
2668 * infrun.c (wait_for_inferior): When program has terminated, we
2669 have to call target_terminal_ours before we pop that target off
2670 the stack (e.g. before a call to target_kill or
2671 target_mourn_inferior). This fixes problem where a program
2672 terminates, then GDB stops for (tty output) and you have to type
2673 "fg" to the shell to resume it. FIXME: This code for what to
2674 do after termination really should be in normal_stop instead.
2676 * gdbcore.h (read_memory_check): Change declaration; it changed
2679 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
2680 4.4 prereleases, this avoids a bug in their sgtty compatability
2682 * remote.c: Use terminal.h rather than hand-rolling the same.
2684 * signame.c, signame.h (psignal): Arg is unsigned, not int.
2685 * utils.c (strsave, strstr): Fix arg types.
2686 * valprint.c (val_print): lint
2688 MIPS symbol table support from Per Bothner:
2690 * symfile.c (symtab_fns): Remove initializer table that needs to
2691 be hacked for each new symbol file format supported.
2692 (add_symtab_fns): New function, chains symbol table
2693 handlers into the global list.
2694 (symfile_init): Search this list.
2695 * symfile.h: Add next pointer, declare add_symtab_fns.
2696 * coffread.c (_initialize_coffread): Call add_symtab_fns.
2697 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
2699 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
2700 symbol *). Thus, we no longer need the hack to trash
2701 pst->filename. Good, since that hack confused code in symfile.c!
2703 (reorder_symtabs, destroy_all_symtabs): Removed static
2704 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
2705 Instead, the latter now uses a temporary array (stack-allocated
2706 from an obstack, and then freed).
2708 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
2709 haven't been set in the outermost stBlock of a procedure. This was
2710 a problem with f77 binaries on Ultrix 4.?.
2712 (new_symtab, new_symbol, new_type): Continue changing code to use
2713 obstacks more and otherwise conform to dbxread internal style.
2714 Made the free_code of symtabs be free_linetable (as in dbxread)
2715 instead of free_contents. This implies memory leaks when reading
2716 a new symbol table, until the conversion is finished. Did change
2717 (struct symbol) and (struct type) to be allocated on the
2718 symbol_obstack. Blocks and blockvectors are among the things
2721 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
2722 tested much, but it solved one problem (reported by Meissner), and
2723 cleans up some other things. The problem happened when an
2724 included file contains actual code (functions) and not just
2725 definitions. The mips coff is a little inconvenient there, since
2726 it may cause a procedure to be mapped to the wrong psymtab.
2728 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
2729 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
2730 this will need work for the new core paradigm.
2732 Opcode patches from the net:
2734 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
2735 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
2736 missing altogether - they are added here. From Bruce Bauman.
2737 * mips-opcode.h: The low mask for C0 instructions was too small.
2738 From Garrett Lau. I modified the fix to check the entire 32-bit
2741 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
2744 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2746 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
2748 * dbxread.c (read_type): Pointer subtraction (value_sub in
2749 valarith.c) sometimes failed because the types of the
2750 pointers being subtracted were not identical.
2751 These differed because dbxread.c was allocating pointer types
2752 using dbx_alloc_type+smash_to_pointer_type instead of
2753 lookup_pointer_type. I failed to find a justification for the
2754 former, so I changed it to use the latter. Similarly, I
2755 replaced smash_to_function_type by lookup_function_type,
2756 and smash_to_reference_type by lookup_reference_type.
2758 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
2759 _initialize_mipsread): corresponding changes.
2761 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
2763 * source.c (mod_path): Do tilde_expand on each component of the path,
2764 rather than on the (list of) paths as a whole.
2765 (print_source_lines): Set first_line_listed in addition to
2766 current_source_symtab and current_source_line. If the source was
2767 not findable, after a "dir" command to fix the problem,
2768 a "list" would get the wrong lines.
2770 While I was there... (gnu):
2772 * dbxread.c (read_type): Change error to complaint.
2774 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2776 First attempt at detailed understanding of symbol table memory alloc.
2778 * dbxread.c (dbx_symfile_read): Free our string table if we
2779 aren't the mainline. Free the "info" struct since we're done with
2781 (init_psymbol_list): Free any previously allocated psymbol lists.
2782 (): FIXME: Should realloc-down the psymbol lists when done reading
2783 the main symbol file?
2785 * symmisc.c (free_symtab): Free fullname field too.
2787 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
2788 (REGISTER_ADDR): Make result type unsigned int.
2790 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
2791 define REGEX must also define REGEX1 (its dependency).
2793 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
2795 * tconfig/i960: No longer works, points you at vxworks960 or
2798 * xgdb.c, XGDB-README: Remove file. Users can get the much
2800 * Makefile.dist: Remove all trace of xgdb.
2802 * breakpoint.c (breakpoint_1): Pass demangle arg to
2803 print_address_symbolic.
2804 (clear_breakpoints): Remove unused function.
2805 (breakpoint_re_set_one): Guts of breakpoint_re_set.
2806 (breakpoint_re_set): Use catch_errors to do them all anyway.
2808 * gdb-int.texinfo (Host versus Target): Add section on what is
2809 a "host" feature versus what is a "target" feature.
2811 * infcmd.c (path_command, path_info): Handle the PATH variable
2812 (object search path) as conveniently as the source search path.
2813 * environ.c (set_in_environ): Set some vars in GDB's environment,
2814 in addition to the child's. PATH, G960BASE, G960BIN for starters.
2815 * source.c (mod_path): New function, from guts of
2816 directory_command, modifies a path. Used by path_command.
2817 (directory_command): Call it.
2818 * defs.h (strsave): Declare.
2820 * utils.c (sevenbit_strings): Add new printing option.
2821 (printchar): Use it.
2822 (strsave): Provide this handy helper routine.
2823 (set_width_command): Rename set_screen_width_command.
2824 (_initialize_utils): "set screen-width" => "set width";
2825 "set screen-height" => "set height"; add sevenbit-strings.
2827 * infcmd.c (do_registers_info): Print floating point registers
2828 in raw hex as well as float format, regardless of whether it is
2829 a "virtual" convertible register.
2830 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
2831 regs as a double, just in case it's being used that way.
2832 * values.c (unpack_long): Comment on array/function coercion.
2833 (unpack_double): Argument is in target byte order now. For
2834 integer arguments, just call unpack_long and float the result.
2835 * m68k-tdep.c: include defs.h for "const" handling.
2836 * remote-nindy.c: Use ieee-float stuff.
2837 (nindy_fetch_registers): Unpack double regs to host double, then
2839 (nindy_store_registers): Pack extendeds to host double, flip
2840 around by misusing unpack_double, send as target double.
2842 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
2843 zero, as when stopped at the first instruction of a process.
2845 * blockframe.c: Fix filename in comment (param.h => tm.h).
2846 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
2847 * tm-68k.h: Fix typos.
2849 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
2851 Changes from a bringup on the DEC Vax under Ultrix 4.0.
2853 * coredep.c (fetch_core_registers): Pass end-address of register
2854 section to register_addr as expected. Don't call supply_register
2855 if we'd just pass it garbage.
2857 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
2859 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
2861 * target.c (push_target, target_info): Cast enums to int for < or
2864 * stack.c (print_frame_info): Identify source file & line
2865 even if we can't print it.
2867 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
2869 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
2871 Clean up IEEE floating point support.
2873 * ieee-float.h: New file.
2874 * ieee-float.c: Write real routines to convert between host
2875 doubles and various target IEEE extendeds.
2876 * m68k-xdep.c: Eliminate assembler code for extended floats.
2877 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
2878 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
2879 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
2880 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
2881 double_to_ieee_extended.
2882 * i960-tdep.c: Define ext_format_i960.
2883 * m68k-tdep.c: Define ext_format_68881.
2884 * sparc-tdep.c: Define ext_format_sparc, though unused.
2885 * Makefile.dist (HFILES): Add ieee-float.h.
2886 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
2889 Obsolete the "coffstrip" program in favor of using BFD's strip.
2891 * nindy-share/coffstrip.c: Remove file.
2892 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
2893 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
2894 * tconfig/nindy960: Remove reference to coffstrip.o.
2896 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
2898 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
2900 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
2901 * dbxread.c: Remove static symfile_bfd.
2902 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
2904 * inftarg.c (child_detach): Pop the child_ops vector if the
2905 detach is successful.
2906 * remote-nindy.c (nindy_create_inferior): Don't push a new
2907 nindy_ops since nindy uses the same one for execution and memory
2909 * core.c (core_ops): Use child_attach and child_create_inferior
2910 rather than default attach and create_inferior functions.
2912 Handle floating point registers in core files.
2914 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
2915 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
2916 This version untested since BFD doesn't yet support sun3 core
2918 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
2919 conventions. Fix comments and style. This version has not
2920 been compiled yet, since we have no HP inhouse.
2921 * core.c (get_core_registers): Look for two sections, ".reg"
2922 and ".reg2", and pass both to fetch_core_registers sequentially.
2924 Revise directory path yet again.
2926 * source.c (forget_cached_source_info): Not static any more.
2927 (init_source_path): New default source path is "$cdir:$cwd".
2928 (dir_command): Handle variable arguments ($cdir, $cwd).
2929 (source_info): Print "Compilation directory" rather than
2930 "Originally compiled in" to remind people of $cdir.
2931 (openp): If the path contains $cwd, use current directory.
2932 (open_source_file): If compilation directory is known, replace
2933 first $cdir in path with the compilation directory.
2934 (print_source_lines): Even if we can't print the lines, set the
2935 current symtab and line for future commands like "info source" or
2936 "breakpoint". Also, error message now contains the file name,
2937 line number, and file access error message.
2938 (_initialize_source): Fix help text to describe changes.
2939 * main.c (cd_command): Forget cached source info when we chdir.
2940 * utils.c (strstr): Add simple implementation.
2942 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
2944 * coffread.c (read_one_sym, init_linetable, init_stringtab):
2945 Byte-swap COFF symbol tables if necessary when reading them in.
2946 Use complain() to replace error message in one spot. Needs
2947 corresponding change in bfd/coff-code.h to make some symbol
2948 swapping routines non-static.
2950 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
2952 Merge changes from Eirik Fuller, for UTek.
2954 * defs.h (errno): Add declaration.
2955 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
2956 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
2957 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
2958 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
2959 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
2960 declarations of errno.
2962 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
2964 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
2965 <rpc/rpc.h> and <rpc/types.h>.
2967 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
2969 * i960-tdep.c (examine_prologue): Add new argument limit,
2970 which stops the scan at the end of the prologue, or at the PC.
2971 This fixes a problem where it walks down into the code for the
2972 user's statements if that code looks like function prologues.
2973 Mark Fox and I have been bouncing this code back and forth, making
2974 small changes to it. Callers changed to match.
2976 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
2978 Cleanup for gdb-3.94 release final:
2980 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
2981 the .c files from vx-share and nindy-share, from the various
2982 macros, since they are not found via ALLDEPFILES.
2983 (SFILES): Add tm-i960.h.
2984 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
2985 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
2987 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
2988 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
2990 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
2992 * am29k-tdep.c: Add contribution line.
2993 (examine_prologue): Cache information about function prologues in
2994 the misc-function-vector to avoid lots of references over the
2995 serial line while examining instructions.
2997 * core.c (core_close): New function made from cleanup_core.
2999 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
3000 remote-vx.c, remote.c, target.c, target.h,
3001 Update target_ops vector to add attach, close, and load entries.
3002 Use add_syms_addr_command, not add_file_addr_command, for
3003 add_file. Break out close routine from existing code.
3005 * dbxread.c (really_free_pendings): Don't free pending_blocks;
3006 they are in an obstack.
3007 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
3009 (define_symbol): Add symbol type parameter; change callers;
3010 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
3011 it to influence the symbol class on the i960.
3012 (define_symbol): Swap LOC_CONST's into target byte order.
3014 * exec.c (exec_close): New function.
3015 (exec_file_command): Call it.
3017 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
3018 Fix byte order of frame pointer.
3019 (read_var_value): Result of 0 if var's value can't be found,
3020 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
3021 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
3022 (locate_var_value): Use read_var_value and use its lazy address
3023 as the location of the var's value. Lint.
3025 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
3028 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
3029 obsolete Intel versions in favor of vxgdb versions.
3030 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
3031 code dealing with byte order of values, which Intel did in host byte
3032 order rather than gdb-4's target byte order.
3033 (i960_frame_chain_valid): Move to nindy-tdep.c.
3034 (examine_prologue, skip_prologue, frame_find_saved_regs,
3035 frame_args_address, leafproc_return, saved_pc_after_call,
3036 pop_frame): Add vxgdb versions from Mark Fox.
3037 (examine_prologue, frame_struct_result_address): Add code
3038 to deal with the saved value of G13 (struct return address
3040 (frame_args_address): Modify Mark's version to prefer the
3041 saved value over the current value in the topmost frame.
3042 Cache result in the frame info to avoid performance hair in
3044 (print_fault): Add gdb960 code for printing faults.
3045 (_initialize_i960): Actually call check_host.
3047 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
3048 add stub routines. FIXME, these currently just return zero!
3050 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
3051 (attach_command): Call target_attach, not target_open, now.
3053 * infrun.c (normal_stop): Make global, not static, for vx_attach.
3054 (child_attach): Rename from child_open.
3055 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
3056 don't confuse it with a zero step_resume_break_address.
3058 * inftarg.c (child_detach): Eliminate inferior_pid test.
3059 (child_files_info): Clean up message a bit.
3060 (child_ops): Use child_attach, not child_open, to attach.
3062 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
3063 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
3064 findvar.c to here, since it depends on the contents of the
3065 shadow_contents of breakpoints, but keep if #if 0 since it is
3068 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
3071 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
3072 (ptype_command, display_command): Eliminate have_inferior_p and
3073 have_core_file_p in favor of target_has_stack or
3074 target_has_execution.
3075 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
3076 code for actually finding the values of arguments, though we still
3077 keep track of the maximum stack offset for use in printing unnamed
3078 arguments. Handle missing FRAME_ARGS_ADDRESS.
3080 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
3081 (struct nindy_regs): Define registers passed to/from nindy.
3082 (nindy_fetch_registers, nindy_store-registers): Translate between
3083 nindy and GDB formats for the registers.
3084 (dcache_init): Statically allocate the cache, since it was being
3085 allocated by a malloc that was never freed anyway.
3086 (nindy_create_inferior): Error, not core dump, if no exec file.
3087 (nindy_before_main_loop): Use target_load, not target_add_file.
3089 * remote-vx.c (net_load): Specify large timeout for load
3090 requests. Allow user to break out with INTERRUPT.
3091 (net_break): Remove useless code, clean up. Change callers.
3092 (parse-args, skip_white_space, find_white_space): Clean up arg
3093 parsing to cope with quoted strings.
3094 (net_wait, net_quit): Never call error, just return status.
3095 (vx_read_register, vx_write_register): Cleanup status checking.
3096 #ifdef the code based on which CPU we are using (960 or 68k),
3097 FIXME, this should be completely general but it isn't yet.
3098 (vx_xfer_memory, vx_resume): Cleanup status checking.
3099 (vx_run_files_info): Improve message.
3100 (vx_load_command): Renamed from vx_add_file_command. Allow load
3102 (net_ptrace): Remove unused routine.
3103 (vx_wait): Adopt code from vxgdb960 to cope with broken
3104 connections to target machine and prompt to disconnect. Remove
3105 debug printouts. Map some EVENT_'s to SIGnals.
3106 (add_symbol_stub, vx_open): Print names of object files we found,
3107 and "ok" if we read their symbols OK. Clarify output in general.
3108 (vx_attach, vx_detach, vx_kill): Add these commands.
3109 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
3110 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
3111 "info files" output, and create_inferior, since we already have
3114 * stack.c (frame_info): Replace Frame_unknown with 0.
3115 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
3116 (return_command): Pop until the PC matches as well as the FP,
3117 so it works even if the FP is shared with another function,
3118 as in "frameless" or "leaf" procedures.
3120 * symfile.c (load_command): renamed from add_file_target_command.
3121 (add_syms_addr_command): renamed from add_file_addr_command.
3122 (add_syms_command): Stub to call target_add_syms.
3123 (_initialize_symfile): Change command names and descriptions,
3124 add-file => add-syms, and load from alias to its own command.
3126 * target.c (kill_or_be_killed, maybe_kill_then_attach,
3127 maybe_kill_then_create_inferior): Default for attempts to start
3128 a process, if one is already running, is to ask about killing
3129 it and retry if yes.
3130 (upstack_create_inferior): #if-0 it, strata obsolete it.
3131 (push_target, unpush_target, pop_target): to_close() a target
3132 before unstacking it.
3133 (target_info): Renamed from target_files_info.
3134 (_initialize_targets): Rename "i files" as "i target", accessible
3137 * target.h: Improve comments about the target_ vectored routines.
3139 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
3140 Convert commenting style to standard GNU style.
3141 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
3142 (SKIP_PROLOGUE): No longer a no-op.
3143 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
3144 (*_REGNUM): Sort register numbers.
3145 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
3146 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
3147 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
3148 are now 10 byte extendeds, not 8 byte doubles.
3149 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
3150 for nindy versus vxworks targets. FIXME, this should possibly go
3151 in the target vector.
3152 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
3153 frame_saved_regs and arg pointer with each frame.
3154 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
3155 (FRAME_ARGS_ADDRESS): Use cached result.
3156 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
3157 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
3158 (PRINT_RAMDON_SIGNAL): Call print_fault.
3159 (POP_FRAME): Now works.
3161 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
3162 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
3163 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
3164 (ADDITIONAL_OPTION_HANDLER): use target_load, not
3167 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
3168 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
3170 * valarith.c (value_subscripted_rvalue): Avoid handling
3171 floats and doubles specially; it gave alignment errors. Lint.
3173 * valops.c (value_of_variable, value_of_this): Error if unknown
3176 * valprint.c (print_floating): Bcopy rather than pointer-deref,
3177 to avoid alignment problems.
3178 (value_print): Handle unknown value address.
3179 (cplus_val_print): Two args are ignored; remove them. Change caller.
3180 (val_print): Use unpack_long rather than pointer-deref.
3183 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
3184 to avoid alignment problems.
3185 (value_being_returned): Error if return value unknown.
3186 (set_return_value): Add bogosity warning, FIXME. *
3188 * TODO: A woman's work is never done.
3190 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
3191 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
3192 Add ieee-float.o to OBS.
3193 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
3194 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
3195 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
3197 Changes to generalize the VxWorks RPC protocol slightly, to handle
3198 i960 as well as 68000.
3200 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
3201 * vx-share/reg.h: Produce i960 regs #ifdef I80960
3202 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
3203 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
3204 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
3205 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
3206 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
3207 so they will move in target byte order rather than network
3208 byte order (happens to be the same).
3210 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
3212 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
3214 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
3217 Add contribution lines to various files, showing where they
3220 * breakpoint.c (break_insn, check_break_insn_size,
3221 read_memory_nobpt): Remove to mem-break.c.
3223 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
3226 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
3227 entry has bad register number. This change is not
3228 tested in this release, FIXME.
3230 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
3233 * value.h: Force value's contents field to be aligned to hold
3234 at least a double or a long long (if supported). This avoids
3235 doing bcopy's in and out of the contents field.
3237 (step_1): Avoid coredump under obscure circumstances when we
3240 * symtab.h (misc_info): Add field to misc function vector for
3241 any kind of cached information the target code desires. AMD
3242 29000 uses this to avoid repeating examine_function_prologue's.
3244 * coffread.c: Lint. Remove static symfile, read_section_header.
3245 core.c (have_core_file_p): Lint: remove.
3246 expprint.c (print_subexp): Lint.
3247 infptrace.c, valops.c, valprint.c: lint.
3249 Roll in changes from vxgdb-5.0.1:
3251 * symtab.h: Comment byte order of each address class. Add
3252 LOC_LOCAL_ARG for frame-relative args (960).
3253 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
3254 symtab.c, symmisc.c: ditto.
3256 * infrun.c (init_wait_for_inferior): Clear stop_signal.
3258 * remote.c (remote_resume): Error if resume with a signal.
3260 * symfile.c (prim_record_misc_function): Clear misc_info.
3261 (fill_in_vptr_fieldno): Check stub type of arg.
3263 * valops.c (value_cast): Avoid looking up names of types whose
3264 name we don't know, to prevent coredump. Sun CC produces typedef
3265 rtx and the name of *rtx is zero...
3267 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3269 Roll in changes from final AMD 29000 port (Tiemann).
3271 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
3272 for ../include/a.out.encap.h. This might not work now that BFD
3273 is separately compiled. Instead, BFD support for encap will have
3274 to translate machine type 29k into the right COFF_MAGIC.
3276 * infcmd.c: Remove references to inferior_pid that aren't used
3277 in actual ptrace calls; use target_has_execution, etc.
3278 (have_inferior_p): Remove function.
3279 (program_info): Print target info rather than "process number";
3280 avoid gratuitous messages unless from_tty.
3281 (run_stack_dummy, finish_command): Set proceed_to_finish.
3282 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
3283 main.c: Lint. Lose have_inferior_p().
3284 inferior.h (have_inferior_p): Remove, lint.
3285 (proceed_to_finish): Add flag to ask that all regs be saved
3286 by normal_stop, for the few commands that need it, speeding up
3287 serial I/O. Add comments to stop_registers.
3289 * remote-eb.c: Remove newline from breakpoint message we grep
3290 for. Never time out when running the user program.
3294 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3296 Roll in changes from vxgdb-5.0.1:
3298 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
3299 symbol in its raw form, we are processing an unlinked ".o" file.
3300 See if the target environment has assigned it an address, using
3301 target_lookup_symbol (VxWorks does), and enter it into the symtab
3304 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
3305 68k versions for a simpler version that assumes zero FP at bottom.
3306 Fixes bug of truncated stack reports.
3308 * target.h (target_lookup_symbol): Define this routine's args
3309 and result, finally.
3311 * target.c (nosymbol): Default routine for target_lookup_symbol.
3312 (target_default): Default lookup_symbol and call_function too.
3313 (files_info): Only print has_all_memory warning if a non-dummy
3316 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
3317 vx_convert_from_virtual): If target does not have floating point,
3318 zero register "values", and avoid doing cross-net conversions.
3319 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
3320 (vx_open): Rearrange code that attaches to target and reads
3321 symbols for all loaded modules, to work if some of the modules
3322 are not accessible. Add symbol_stub() and add_symbol_stub()
3323 as callbacks from catch_errors(). Allow connect attempt to be
3324 interrupted painlessly with ^C (FIXME, there are still some bugs
3325 if the interrupt happens during symbol reading.). Print
3326 final message with puts_filtered, since symbol messages are
3331 * main.c (catch_errors): Only print errstring if non-null.
3332 (command_loop): Avoid an ioctl per command to test ISATTY.
3334 * remote-vx.c (net_load): make static; avoid sophomoric msg.
3335 (vx_xfer_memory): Return correct result!
3336 (vx_files_info): Indicate whether target has float or not.
3337 (vx_lookup_symbol): Complain, not error, if target gone.
3338 (vx_open): Print "Connected" msg before disabling immediate-quit.
3339 [FIXME: lookup_symbol and vx_open changes need testing.]
3341 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
3342 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
3343 contributor lines and update copyrights to 1991.
3345 Changes from an attempted H-PUX host port:
3347 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
3348 defines PT_ATTACH and PT_DETACH but not PT_KILL.
3349 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
3350 * remote-vx.c: include <sys/time.h> for HPUX.
3351 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
3352 "core_file_command" routine to BFD regime. May not work yet.
3354 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
3356 * xgdb.c: Replace X10 version with some VJ version.
3357 (FIXME: Its copyright assignment is not on record.)
3358 * xgdb.c: Update include files to X11R4 (Xaw crud).
3359 (xgdb_display_source, create_text_widget): fix call to
3360 get_filename_and_charpos. Rewack source window stuff for X11R4
3361 (gleaned from include files, and "nm's" of binary libraries, since
3362 I had no doc available).
3363 (append_selection, append_selection_word): Disable with FIXME
3364 since R4 changed interface here.
3365 (create_buttons): Add back the old set of buttons.
3366 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
3368 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
3369 Roll VERSION to 3.94 (not yet final though).
3371 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3373 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
3374 obstack_int_grow, obstack_int_grow_fast): Eliminate
3375 cast on left of assignment, which gives MIPS cc fits and is
3378 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
3379 F_ALIAS. Use printf, not fprintf, when not passing a file
3381 (compare_opcodes): Check that identical instructions have
3382 identical opcodes, complain otherwise.
3384 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
3385 was reported by Roland McGrath.
3386 (unimp): Only match if exactly zero instruction. (Roland)
3387 (branches and traps): Generate all variations of these
3388 instructions with macros, based on a single call that defines
3389 each condition name and its binary representation.
3390 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
3392 * valprint.c (val_print_fields): Take, and use, format parameter.
3393 This means that "p/x struct" again prints the elements in the
3394 desired format. Changed callers.
3396 * stack.c (frame_info): Use filtered output, and indicate wrap
3397 points. Remove kludgy formatting designed to avoid line wrap.
3399 * utils.c (wrap_here): If the line is already full (because
3400 we had printed a long indent or long wrapped string), do an
3401 immediate newline-and-indent.
3403 * m68k-pinsn.c (print_insn_arg): Bugfix from
3404 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
3405 instruction is incorrectly disassembled as bkpt #8.
3407 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
3408 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
3409 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
3410 and then will dump core (sometimes). I traced it back to an
3411 uninitialized symfile_name in psymtab_to_symtab.
3412 (const_vol_complaint): Add quotes to message.
3413 (define_symbol): Only believe line number if gcc_compiled.
3414 Avoid allocating symbol if we will not return it.
3416 Add target strata support so that newly established targets go
3417 into their right place in the target stack (e.g. a new exec file
3418 doesn't wipe out the ability to access the running process).
3420 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
3421 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
3422 and initialize it properly in all the targets.
3424 * target.h: Document strata. Change return type of push_target.
3426 * target.c (nomemory): new function for dummy memory access.
3427 (tcomplain): Rename complain, now also used in symfile.c.
3428 (push_target): Push targets within strata. New return value shows
3429 whether new target is on top of stack or not. Always keep dummy
3431 (target_files_info): Ignore dummy target.
3433 * core.c (core_open): Warn user, and skip accessing file, if the
3434 core target is not the topmost target in the stack.
3435 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
3438 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
3439 target_ops, it doesn't belong there since we have no regs there.
3440 Change name of target from machine => memory to clarify.
3442 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
3444 * Freeze version 3.93 for release.
3446 * Makefile.dist: Handle vx-share and nindy-share subdirs
3447 properly when building gdb.tar.Z.
3449 * symtab.c: lint; add no_symtab_msg to consolidate the messages
3450 printed in various places, so I could change just one copy.
3452 * dbxread.c, coffread.c: Change references to bfd->iostream
3453 to cast to FILE *, now that BFD avoids needing types defined
3454 in other header files.
3456 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3458 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
3459 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
3460 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
3461 (actually gcc -Wall).
3463 * dbxread.c: Remove first_global_sym, last_global_sym, since
3464 they are never referenced.
3466 * defs.h (baud_rate): Declare.
3467 main.c: Define it, and add the -b option to set it.
3469 * gdb-int.texinfo: Add text on how to define a new host or target
3470 architecture, prompted by Per Bothner's questions about MIPS
3473 * gdb.texinfo: Document "complaints". Change doc of -q since
3474 gdb no longer prints the copyright and blurb if you specify a file
3475 name to be debugged (just like Emacs). Add doc for Nindy-specific
3476 command line flags for specifying target serial port and such.
3477 Update copyright to 1991.
3479 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
3480 has taken over for us the job of ripping up executable files. The
3481 crud caused Per Bothner's port to not compile.
3483 * infrun.c (normal_stop): Avoid printing "Program exited
3484 normally" if we are in batch mode. This allows a GDB which
3485 executes a program on a target system, to behave like a Unix
3486 command (input from stdin, output to stdout, no extraneous
3489 * main.c (main): Allow additional machine-dependent command line
3490 options to be specified with the ADDITIONAL_OPTIONS,
3491 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
3492 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
3493 processing to occur just before the main loop with
3494 BEFORE_MAIN_LOOP_HOOK.
3495 (main): If a "core file" argument is specified, and it is not a
3496 core file, try it as a process ID to attach.
3497 (symbol_completion_function): Attempt to cope with
3498 "show screen-" TAB, not very successfully. This needs more work,
3500 (batch_file): New function, returns whether we are reading
3501 commands from an interactive tty on stdin, or from somewhere else.
3502 Called by normal_stop since it doesn't get from_tty passed down
3503 to it like many commands do.
3505 * remote-nindy.c: Handle command line options for nindy
3507 (nindy_before_main_loop): Prompt user for tty name if they
3508 don't specify it before getting to the interactive command loop.
3510 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
3511 and -r command line options. Also add hook before main loop
3512 to make it easy to specify a tty.
3514 * TODO: More things to do, one done.
3516 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
3518 * dbxread.c: Make complaint() calls pass pointer, not struct.
3519 Add complaints about badly formatted C++ type information
3520 (const/volatile indicator, and parse errors resulting in
3521 error_type). Fix C++ virtual member fn comment.
3522 (read_struct_type): Avoid bumping pointer if we got a parse
3523 error; this prevents our walking beyond the end of a string.
3524 Terminate loop on null char as well as semicolon.
3525 (process_one_symbol): Fix the LBRAC fix so that it uses the
3526 last previous SLINE, FUN, or SO record's PC address. C++ debug
3527 symbols did not have SLINE records in a useful order compared
3528 to the LBRAC records.
3529 (define_symbol): Handle "catch" records.
3531 * symtab.c (check_stub_type): Added new complain
3532 `stub_noname_complain' and added a consistency check to
3533 keep the debugger from crashing when finishing from an
3534 exception frame. A real fix will be needed later.
3536 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
3538 * infcmd.c (attach_command): Make global.
3540 * Makefile.dist (REMOTE_OBS): Make these compile by default,
3541 but make them easy to comment out. Perhaps later they should
3542 be enabled by what CPU you configure for? FIXME.
3543 (VERSION): Roll to 3.93.
3544 (pinsn.o): Remove rule for obsolete file.
3545 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
3547 Run down a problem that manifested by printing the wrong function
3548 name in stack traces of read_ofile_symtab. Turned out that the
3549 problem was the SunOS 4.1.1 (and previous) C compiler outputs
3550 the LBRAC symbol with an address in the *data* segment, which
3551 blew our binary search through the blocks.
3553 * dbxread.c: Use the complain() facility consistently to bitch
3554 about problems in the symbol file we are reading.
3555 (finish_block): Add code to check the nesting of the blocks;
3556 complain and Procrust them to fit if wrong.
3557 (make_blockvector): Check the order of the blocks, complain
3558 [but don't cope] if wrong.
3559 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
3560 symbols to be sure their PC value is greater than the last SLINE
3561 (line number) symbol we've seen, complaining and adopting the
3562 SLINE PC value if wrong.
3564 * symfile.h (struct complaint, complaint_root, complain,
3565 clear_complaints): Add.
3566 * symfile.c (complain, complaint_root, clear_complaints): Add
3567 facility to deal with non-fatal complaints and to regularize their
3569 (symbol_file_add): Clear complaint counters to allow new complaints.
3570 (initialize_symfile): Add 'set complaints' and 'show complaints'.
3572 * dbxread.c (dbx_symfile_read): Remember the address and size
3573 of the string table for the main symbol file, so we won't read it
3575 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
3576 to avoid reading the string table yet again. Lint.
3577 (throughout): Improve filtered output, including word wrap.
3578 (read_range_type): Improve Bothner's fix to handle other types too.
3580 * utils.c: Improve line wrap implementation. Handle unlimited
3581 width by making chars_per_line unsigned.
3582 (puts_filtered): New, easy, function.
3584 * defs.h (puts_filtered): add.
3586 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
3587 call the identical sort_symtab_syms() in symfile.c instead.
3589 * expread.y: Suggest the `file' command rather than `symbol-file'.
3591 * command.h (enum var_types): Add zinteger for seroable
3593 * command.c (do_setshow_command): Handle var_zinteger. Restructure
3594 nested if's into a switch.
3596 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
3597 we did not stop because of a breakpoint (it must have been for
3598 some other reason, like a "stepi"), so don't print anything.
3600 * symtab.c: Include <sys/types.h> all the time. Now that BFD
3601 doesn't include <sys/types.h>, old SunOS's require it for
3604 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
3606 A test port of gdb-3.92.6 to the Sony NEWS.
3609 Don't normally link in remote- or vx stuff.
3610 Some of it doesn't compile, and it wastes space for 99% of the users.
3611 Remove reference to no-longer-used HAVE_VPRINTF.
3612 Fixed BFD_DEP typo to BFD_DIR.
3614 Fix cast in arg to bfd_h_getlong.
3615 Make char *prefix be const.
3616 Fix how certain range types are mapped into builtin unsigned int types.
3618 Remove 2 #includes. They cause errors (on Sony, at least),
3619 and aren't needed (they wern't in earlier versions).
3621 print_address_symbolic should never demangle labels
3622 (since it prints *assembler-level* labels).
3624 [This was superseded by the change to printcmd below.]
3627 Add some "volatile" return types to avoid warnings.
3628 If MISSING_VPRINTF add vprintf function and not just macro
3629 (since vprintf is used in printcmd.c).
3631 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
3632 (The latter isn't grokked by some PCC-based compilers.)
3634 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
3636 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
3637 * nindy-share/coffstrip.c
3638 Added some forward declarations (otherwise, gcc complains
3639 about implicit extern redefined as static).
3641 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
3643 Changes inspired by Per Bothner:
3644 * printcmd.c (print_address_symbolic): Take additional parameter
3645 specifying whether to demangle.
3646 (print_address): Pass in asm_demangle to control demangling.
3647 (print_address_demangle): New fn, takes explicit arg to control
3649 * utils.c: Add new vars demangle and asm_demangle, and let them
3651 (fputs_demangled): If !demangle, just print the argument.
3652 (fprint_symbol): If !demangle, just print raw symbol.
3653 * valprint.c (val_print): Call print_address_demangle rather than
3654 print_address, to cause demangling to depend on the global
3655 rather than assembler-level demangling setting.
3656 * WHATS.NEW, gdb.texinfo: Document.
3658 * main.c (show_command): Show all settings if no arg.
3659 (initialize_main): Make "info set" the same as naked "show".
3660 * command.c (cmd_show_list): Handle prefix commands in the
3661 list, and print the name of the setting as well as its English
3662 description and value.
3664 Allow gdb functions to specify where a line should wrap if it
3665 exceeds the size of a terminal line. Use it to make the output
3667 * utils.c (set_screen_width_command): New fn, mallocs a buffer
3668 of the right size when screen width changes.
3669 (set_screensize_command, screensize_info): Remove #if 0'd fns.
3670 (wrap_here): New fn, indicates a point in the output where we
3671 should wrap the line rather than just letting it overflow at a
3673 (fputs_filtered): Implement wrapping.
3674 (n_spaces): New fn, returns a pointer to N spaces.
3675 (print_spaces_filtered): Use n_spaces.
3676 * defs.h (n_spaces): Declare.
3677 * stack.c (print_frame_info): Wrap with 4-space indent after
3678 fn name and before filename and line number.
3679 * printcmd.c (print_frame_args): Wrap with 4-space indent
3680 before each argument name is printed.
3681 * valprint.c (value_print): Wrap with no indentation before
3683 (val_print_fields): Wrap with indentation relative to nesting
3684 level before each field name.
3685 (val_print): Wrap with nesting indentation before array elements.
3686 * command.c (do_setshow_command): Avoid extra newlines,
3687 wrap with 4-space indent around values printed, end with period.
3688 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
3690 * breakpoint.c (breakpoint_1): Implement addressprint for
3691 "info breakpoints" display. Change file name and line number
3692 format to " at file:nnn" rather than " (file line nnn)".
3693 * gdb.texinfo: Document.
3696 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3698 Frozen for gdb-3.92.6 release.
3700 README, WHATS.NEW: Update for 3.92.6 release.
3702 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
3703 coffread.o from configs since it is now built by default.
3704 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
3705 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
3706 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
3707 from configs since it is now built by default.
3709 Makefile.dist: Update for release 3.92.6. Handle files that
3710 have been moved to ../include, ../getopt, or ../bfd. Add
3711 saber.suppress and tests directory. Add config.status to
3712 the release (it will say "none").
3714 coredep.c: Minor formatting fixes.
3716 These changes were made in early December but only checked in now:
3717 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
3718 nindy-share/nindy.c: lint
3719 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
3720 register values coming back from the target; we store values
3721 in target byte order everywhere.
3723 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
3725 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
3727 * valprint.c (cplus_val_print, val_print_fields): New functions,
3728 which print C++ objects. They conspire to avoid printing a
3729 virtual base class more than once, following all the twists and
3730 turns of C++ virtual base rules.
3731 (val_print): Call the above rather than do it by hand.
3733 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
3734 symbol file, not for added files like shared libs. This really
3735 needs to be generalized to a timestamp per file.
3737 * core.c (cleanup_core): Avoid coredump if no core file.
3739 * config.gdb: Accept -host or -target in place of +host or
3742 * coffread.c (find_linenos): Avoid desupported BFD interface
3743 to line numbers. We still read them manually rather than using
3744 BFD's "generic" features.
3746 * gdbrc.tex, threecol.tex: Add GDB reference card and its
3748 Makefile.dist: Add refcard to OTHERS list for creating tar files.
3750 * Makefile.dist: Eliminate use of $< in explicit targets.
3752 * readline/Makefile: Use $< rather than $*.c, which does not
3753 include the VPATH in GNU Make.
3755 * tconfig/i960-bout, tconfig/i960-coff: These are identical
3756 copies of tconfig/i960, added for global configuration
3757 compatability. All i960 versions can read both coff and b.out.
3759 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
3760 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
3763 * TODO: Think of more things to do.
3765 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
3767 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
3768 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
3769 64-bit float conversion.
3771 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
3772 equivalent to sun?os4 so global config works.
3774 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
3776 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
3778 * main.c: Only declare linesize once; declare pagesize not at
3779 all, since it is never used.
3780 (main): Clear newly allocated line before it is used.
3782 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
3784 Further stabilization for the Intel 960.
3786 * Makefile.dist: Parameterize the location of the "include"
3787 and "bfd" directories, as well as "getopt". Add symfile.c.
3788 Link in both dbxread and coffread. Fix up "make depend" to
3789 rewack the locations of include, bfd, and getopt in its output.
3791 * README: Document moving include files, improve some of
3794 * coffread.c: Move common code out to symfile.c. Change
3795 symbol_file_command style interface to use new *_symfile_init
3796 and *_symfile_read interface under BFD. Use BFD internal
3797 info to locate line table, symbols, etc.
3799 * core.c (core_fetch_registers): Rename to get_core_registers
3800 to avoid confusion with fetch_core_registers.
3801 (register_addr): Move to coredep.c, which is already machine
3802 dependent. This leaves core.c pretty clean of dependencies.
3804 * coredep.c (register_addr): Accept this routine from core.c.
3806 * dbxread.c: Move common code (with coffread.c, etc) into new
3807 symfile.c. Each psymtab now contains a pointer to the
3808 format-dependent function that knows how to read it in. Make
3810 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
3811 (process_one_symbol): Add code to complain about a "compiler bug
3812 we muzzle here", if we actually see it.
3814 * eval.c (evaluate_subexp): Insert missing "break" statements
3815 in code that determines whether a variable is an lvalue in
3816 memory, register, or whatever. I detected this via a compiler
3817 bug in which it *almost* mashed out the whole switch statement.
3819 * gdb-int.texinfo: Add minor sections on configuring gdb for
3820 release, and about the README file.
3822 * infcmd.c (registers_info): Fix formatting somewhat. Still
3823 not as pretty as before, but it handles byte swapping.
3825 * remote-nindy.c: If data cache routines are interrupted while
3826 waiting for the remote end, be sure that any uninitialized cache
3827 blocks are on the free list, not on the valid list!
3829 * symfile.h: Flesh out this header file with all the various
3830 routines and variables that have been merged in from dbxread.c
3831 coffread.c, and symtab.c to symfile.c.
3833 * symfile.c: New file, containing code common to dbxread.c,
3834 coffread.c, and some code from symtab.c. All generic code for
3835 reading symbol files should be in here now.
3836 (unrecord_misc_function): Remove unused function.
3838 * symtab.h: Remove file-reading things to symfile.h.
3840 * symtab.c: Remove file-reading things to symfile.c.
3842 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
3843 to decode i960 fault types.
3845 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
3846 target.c: Change type of the "resume" function from int to void,
3847 since its result was never used.
3849 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
3851 * main.c: Replace "stupid" with "caution"; you now "set caution
3854 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
3856 * infcmd.c (do_registers_info): Call val_print to deal with the
3857 byte order of the registers being printed. FIXME, this makes
3858 the formatting of the output uglier.
3860 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
3861 defined, call it for signals the debugger doesn't itself use.
3862 The i960 uses this for more detailed fault information.
3864 * remote.c (remote_open): If arg is null, print help rather than
3867 * sparc-xdep.c (register_valid): Avoid declaring size, since
3868 various modules will think of various sizes depending on the
3869 architecture of their tm-file. FIXME, we need protection against
3870 actually entering one of those modules, which would clobber
3871 storage if not for the target architecture compiled into gdb.
3873 * stack.c (up_command, down_command): Always print the frame
3875 (up_silently_command, down_silently_command): New commands
3878 * i960-pinsn.c (reg), i960-tdep.c: Lint.
3880 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
3881 more parameters than it used to.
3883 * findvar.c (registers): Increase slop to 256 bytes, which should
3884 protect us against even most RISC machines with large register
3886 (locate_var_value): Move declaration inside related ifdef.
3888 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
3889 throughout, to avoid throwing away buffered input from the board.
3890 (nindy_wait): Supply_register takes addr_of_value, not value.
3891 (i960_print_fault): Renamed from i80960_fault.
3892 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
3893 (nindy_store_registers): Avoid regs_changed stuff, just stuff
3895 (nindy_create_inferior): Don't bother to write PC_REGNUM since
3896 we can set the PC in the call to proceed(). Unpush nindy_ops
3897 before pushing it on top, to avoid message to user. Eliminate
3898 commentary from Unix machines that just misleads here.
3899 (reset_command): Fix error message to suggest target command.
3901 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
3903 Release 3.92.5 as frozen.
3905 Stabilize the merged release...with help from lint, Saber C,
3908 Everywhere: Add include files needed to declare return types
3909 of functions called.
3911 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
3913 * breakpoint.h: Add undeclared breakpoint functions, and some
3914 functions for display handling since I couldn't think of a better
3917 * breakpoint.c (insert_breakpoints): Make code for disabling
3918 shared library bkpts more likely to work. It's used when we
3919 rerun a program and stop before the shared library has been
3921 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
3922 cast from pointer, so it squeezes through catch_errors.
3923 (bpstat_stop_status): Fix logic broken some time ago. We now
3924 always create a bpstat if the stop address matches a breakpoint,
3925 even if we don't stop there -- just like the old code used to do
3926 before I got my fingers into it (sigh).
3927 (breakpoint_1): Print "ignore count" after "stop only if"
3928 condition, since that's how it actually works.
3929 (mention): Handle watchpoints as well as breakpoints.
3930 (watch_command): use set_raw_breakpoint and mention to do most
3931 of the work (and initialize all the fields!). Only pass one
3932 arg to parse_c_expression, since that's all it takes.
3934 * command.c (not_just_help_class_command): Rename arg to args
3935 since we ignore "unused argument" warnings on vars named "args".
3936 inflow.c (child_terminal_info): ditto.
3937 infptrace.c (kill_inferior): ditto
3938 main.c (catch_errors, version_info, quit_command, pwd_command,
3939 source_command, dump_me_command, editing_info,
3940 set_history_size_command, set_history, show_history,
3942 stack.c (locals_info): ditto
3943 target.c (target_files_info): ditto
3944 valprint.c (set_input_radix, set_output_radix): ditto
3946 * core.c: Remove old variables for handling core and exec file
3947 sections (data_start, data_end, stack_start, stack_end,
3948 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
3949 text_end, exec_data_start, exec_data_end, text_offset,
3950 exec_data_offset, data_offset, stack_offset). They're
3951 superseded the more general build_section_table and
3953 (get_exec_file): Mention the `file' command.
3954 (read_memory_check): Rename to memory_error, and only call it
3955 in the case of an actual error.
3956 (read_memory, write_memory): call memory_error.
3957 (core_fetch_registers): Register section name is ".reg".
3959 coredep.c: Remove a bunch of crud now that all this file does
3960 is pull the registers out of a core file.
3961 (fetch_core_registers): Rewrite to actually work, I hope.
3963 dbxread.c: Use a.out.gnu.h, not system a.out, now.
3964 Replace index() with strchr(). Remove all the pre-BFD macro
3965 definitions for accessing the symbol file.
3966 (struct dbx_symfile_info): Encapsulate the information that
3967 dbx_symfile_init needs to pass to dbx_symfile_read in this
3970 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
3971 dbx_symfile_discard): Rearrange symbol file reading to divide
3972 the format-specific part from the format-independent part,
3973 leaving the format-independent part such as file name expansion
3974 and opening in symtab.c. This replaces
3975 partial_symbol_file_open and partial_symbol_file_read.
3976 Symbol_file_read, add_file, add_file_target_command,
3977 add_file_addr_command move to symtab.c. Pass an explicit
3978 "mainline" flag for when reading the main symbol table, rather
3979 than relying on the offset address to be zero or nonzero.
3981 (dbx_symfile_read): Don't allow void *'s to be printed as
3983 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
3984 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
3985 macro" debug version really work.
3986 (read_dbx_symtab): Remove unref'd parameter inclink.
3987 Avoid swapping N_SLINE symbols, for speed.
3988 Merge N_TEXT!N_EXT case with the other external symbol
3989 definitions' case. Add comments.
3990 (start_psymtab): Allocate the symfile name in the psymtab on
3991 the psymbol_obstack, rather than using the caller's storage.
3992 (end_psymtab): Only allocate a dependencies list if there are
3994 (psymtab_to_symtab_2): Use BFD when reopening file to read
3995 its symbols for real.
3996 (read_struct_type): Add FIXME comments where it needs work
3998 (read_huge_number): Add FIXME about overflows.
3999 (read_range_type): Add FIXME about comparing a long to 1<<32.
4001 * coffread.c: Minor changes to move things closer to the new
4002 regime with symtab.c and dbxread.c Major work is still needed
4005 * exec.c (exec_file_command): Remove old variables (see core.c
4007 (xfer_memory): If memory transfer is right at the end of a
4008 section, don't lose.
4010 * findvar.c (get_saved_register): If value is in a real
4011 register, LVAL is lval_register, not lval_memory.
4013 frame.h: Declare print_sel_frame and record_selected_frame.
4015 gdb-int.texinfo: New file, for GDB internals documentation.
4016 Very simple, unformatted doc of cleanups is there for now.
4018 gdbcore.h: Remove obsolete variables that described a.out
4019 section addresses and offsets. (See core.c above.)
4020 Declare fetch_core_registers and registers_fetched.
4022 getopt.c: Declare char *alloca(); even on SPARC.
4024 infcmd.c (run_command): Call target_kill rather than
4026 (step_command, next_command, stepi_command, nexti_command):
4027 Declare from_tty parameter even though we don't use it.
4028 (run_stack_dummy): argument BUFFER is a char array, not
4029 a pointer to REGISTER_TYPE.
4030 (finish_command): using_struct_return needed a value *,
4031 not a struct symbol *.
4033 * infptrace.c (child_xfer_memory): To avoid dependency on
4034 where sections are in memory, try PT_WRITE_D and if that fails,
4035 try PT_WRITE_I. Most Unixes don't care which you use.
4037 * infrun.c (step_resume_break_shadow): Change to array to
4038 match other breakpoint shadow storage.
4039 (clear_proceed_status): Pass address of bpstat to
4040 bpstat_clear, not the bpstat itself.
4041 (child_create_inferior): FIXME comment about if the child
4043 (start_inferior): Remove old function.
4044 (child_open): Use target_kill rather than kill_inferior.
4045 (wait_for_inferior): Ditto.
4046 (insert_step_breakpoint, remote_step_breakpoint): Use
4047 new step_resume_break_shadow.
4049 * inftarg.c (child_wait): If all child processes die,
4050 pretend that the one being waited for exited with signal 42.
4052 * main.c (command_line_input): When scanning for comments,
4053 don't coredump on unclosed quotes.
4054 (quit_command): Use target_kill rther than kill_inferior.
4055 (_initialize_main): Rename class_user from "user" to
4058 * printcmd.c (print_command_1): Initialize "fmt" if no format
4059 is specified by the user.
4060 (print_frame_args): Only add to args_printed if we are
4061 actually fetching args from the stack (avoiding undefined
4063 (_initialize_printcmd): Remove bogus \{ from string.
4065 * remote-eb.c (eb_open): Avoid coredump on no argument.
4067 * remote-nindy.c: Bring out of Intel environment into new
4068 target environment. Remove all conditional compilation on
4069 I80960. Massive hacking throughout.
4070 (nindy_xfer_inferior_memory): New routine stolen from
4072 (nindy_create_inferior): New routine pieced together, probably
4073 not quite working yet.
4074 (nindy_ops): New target_ops struct for nindy.
4076 * remote-vx.c: Use write_memory rather than target_write_memory
4077 to get error checking.
4078 (vx_add_file_command, vx_open): Use symbol_file_add rather than
4080 (vx_create_inferior): Use target_terminal_ours...
4082 * signame.c (_initialize_signame): Always initialize, since
4083 we need the table for things other than psignal.
4085 * solib.c (solib_add): Use symbol_file_add, not add_file.
4086 (solib_address): Return boolean result rather than struct
4087 pointer which nobody else knows the type of.
4089 * sparc-tdep.c, valops.c: Use write_memory rather than
4090 target_write_memory, to get error checking.
4092 * stack.c (locals_info, catch_info, args_info,
4093 get_selected_block, frame_command, up_command): Use
4094 target_has_stack, rather than have_inferior_p or
4097 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
4099 * symfile.h: New file, defining the interface between the
4100 generic and object-file-specific symbol reading code.
4102 * symtab.c: Move generic symbol-reading interface to symtab.c,
4103 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
4104 table to map BFD targets to symbol-reading modules in GDB.
4105 Change index to strchr.
4106 (lookup_struct_elt_type): Use error() rather than hand-made
4107 simulations thereof.
4108 (lookup_partial_symbol): Speedup slightly when length == 0.
4109 (symbol_file_add): New function.
4110 (symbol_file_command): Call it.
4111 (symfile_open, symfile_init): New function.
4112 (add_file_target_command, add_file_addr_command): moved from
4115 * target.c (target_command): use target_kill.
4117 * target.h (target_files_info): Don't declare, never called
4120 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
4121 files to determine stack end address.
4123 * valarith.c (value_x_binop, value_x_unop): Change error message
4124 to be more useful. Pass proper argument to value_struct_elt.
4126 * valops.c (value_assign): FIXME comment that long long
4127 bitfields will break here.
4129 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
4130 Update `make saber_gdb' to work better.
4132 * TODO: A woman's work is never done.
4134 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
4135 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
4136 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
4137 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
4138 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
4139 valops.c, valprint.c, exec.c: Lint.
4142 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
4144 Continuing Intel 960 port merge of GDB.
4146 * Makefile.dist: Merge i960 "nindy-share" files. Rename
4147 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
4148 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
4149 Wack over "make depend" so it handles files in subdirectories
4150 vx-share, nindy-share, bfd, and in the current directory.
4152 * blockframe.c (get_prev_frame_info): Remove fatal error
4153 if stack not defined.
4155 * core.c (core_open, core_detach): New functions that handle
4156 the old "core-file" command as "target core" and "detach" instead.
4157 (core_file_command): Call them.
4158 (core_xfer_memory): Use common routine xfer_memory.
4160 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
4161 dbxread now uses bfd for everything but symbol reading itself.
4162 BFD internals are used to drag out the relevant file offsets.
4163 (partial_symbol_file_open): Change args all around for BFD.
4165 * symtab.c: Rename "value" to "val" everywhere, so we can
4167 (symbol_file_command): New command, moved from dbxread.c
4168 and coffread.c. It uses BFD to read the file, then vectors
4169 based on its type, to dbx or coff symbol readers.
4170 * symtab.h: Extern a few vars for symbol_file_command.
4172 * target.h: Breakpoint takes a char * save area, not a char **.
4174 * valprint.c (val_print): When unpacking bitfields, offset
4175 the address in gdb of the value, if it is declared with a shorter
4176 type. Remove the last "runtime kludge test" of host byte order.
4178 * utils.c: Remove old my_bfd_read routine.
4180 * stack.c (frame_info): Use target_has_stack. Print program counter
4181 register's actual name rather than "pc", since it's called the
4182 "ip" (instruction pointer) on the i960 (sigh).
4184 * target.c (target_command): Add command for selecting a target
4185 type and calling its open routine. This is used for initiating
4186 communication with a particular target, in a generic way.
4188 * tm-i960.h: Update for modern gdb. Remove semicolons from
4189 various macros. Handle reading struct return convention, and
4190 error-out attempts to return structs with the "return" command.
4191 Be sure gdb doesn't think we know how to call functions in the
4194 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
4195 to i960_xxx in lower case.
4196 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
4197 not being defined yet.
4199 * remote.c (remote_open): Call start_remote to initialize
4200 wait_for_inferior during open.
4201 (remote_xfer_inferior_memory): Return length written rather
4204 * remote-vx.c (target_command -> vx_open): Use new generic
4206 * remote-eb.c, inftarg.c, exec.c: ditto.
4208 * infrun.c: Fix comments.
4209 (attach_program -> child_open): Use new generic target command.
4210 (wait_for_inferior): Clear saved register values before target_wait,
4211 so target_wait can set some of them if convenient.
4213 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
4214 Return success indicator, not void.
4215 (child_xfer_memory): Avoid fetching initial word if we'll
4216 overwrite it anyway.
4218 * infcmd.c (attach_command): Use new generic target open routine.
4219 (_initialize_infcmd): Update doc on attach and detach commands.
4220 (do_registers_info): Merge in a byte-order problem as a FIXME
4223 * findvar.c (find_saved_register): Avoid problem in current frame.
4224 (read_relative_register): Ditto.
4225 (write_register): Convert byte order on the way out.
4227 * exec.c (file_command): Add.
4228 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
4229 (xfer_memory): Common function between core_xfer_memory and
4231 (exec_xfer_memory): Use it.
4233 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
4235 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
4236 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
4237 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
4239 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
4241 Merge Intel 960 port of gdb, continuing...
4243 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
4244 symbol_file_command): Pass from_tty arg to hush 'em up.
4246 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
4247 Add magic numbers for 960 COFF format.
4249 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
4251 Merge Intel 960 port of gdb, from Intel "1.2" release.
4253 CHANGE_LOG entries from their port, which was based on
4256 Thu Sep 6 11:02:22 PDT 1990
4257 Remove temp file if download is interrupted.
4259 Wed Aug 1 09:08:33 PDT 1990
4260 Now uses binary protocol to talk to NINDY.
4261 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
4262 Times out after 5 seconds when trying to talk to NINDY.
4264 Tue May 29 12:54:49 PDT 1990
4265 Added variable baud rate (-b switch).
4266 Source code reorganization.
4268 Thu Apr 26 11:09:55 PDT 1990
4269 More cleanup of batch mode; specifically, execute "-s", "-e", and
4270 "-se" switches as soon as they are encountered on the invocation line.
4272 Fri Apr 20 13:47:15 PDT 1990
4275 Thu Apr 19 09:54:28 PDT 1990
4276 Add 'reset' command.
4278 Wed Apr 18 09:48:07 PDT 1990
4279 After opening remote tty, wait for 1 second to go by without input
4280 from it before trying to talk to NINDY (fixes problems with the
4281 Heurikon HK80/V960E).
4283 Mon Apr 4 16:33:05 PDT 1990
4284 Some output was not being suppressed in 'batch' mode.
4286 Thu Mar 22 15:31:11 PST 1990
4287 Ask user if old symbol table should be deleted when new file is
4290 Allow user to run a program downloaded before gdb960 was brought up.
4292 Correct "exec-file" help message for i80960 context.
4294 Correct bug in calculating user space address: could occasionally
4295 corrupt user program.
4297 Make sure to zero low-order bits in rip's because of bug in 960CA
4298 A-step part: could cause operation faults when "next"ing across
4301 Correct bug that made it impossible to get source line numbers for
4302 code loaded at addresses higher than 0x7fffffff.
4304 Wed Jan 10 12:43:22 PST 1990
4305 Open remote tty for exclusive use.
4307 Fri Jan 5 12:14:42 PST 1990
4308 Correct disassembly (CA manual was right after all):
4309 opcode for sysctl is 0x659
4311 Mon Oct 23 12:03:04 PDT 1989
4312 Use G960BASE and G960BIN environment variables to find 'sx' utility.
4314 Mon Oct 16 14:15:09 PDT 1989
4315 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
4317 Mon Oct 2 15:56:31 PDT 1989
4319 Added 960CA disassembly support.
4321 To simplify maintenance:
4322 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
4324 - eliminated opcode.h: incorporates tables into i960-pinsn.c
4325 - moved 960-specific routines from i960-pinsn.c to i960-md.c
4326 - made disassembly interface identical to that in gdmp960.
4330 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
4332 * target.h: Allow targets to stack. Add target_has_memory,
4333 _registers, etc. Restructure memory access and "info files"
4334 to walk the target stack.
4335 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
4336 target.c: Change tables to match target.h.

4342 * remote-vx.c: New memory regime, new info files. Now use
4343 separate targets for VxWorks attachment to machine, and
4344 actually running a process under VxWorks, since one has
4345 stack & execution & regs and the other doesn't.
4346 * remote.c: New memory regime, new info files.
4347 * sparc-xdep.c (fetch_core-registers): New memory regime.
4348 * target.c: New routines and support for stacked targets,
4349 new memory regime, new info files regime.

4355 * exec.c (build_section_table): Iterate all sections and
4356 record what gdb needs to know about them.

4378 since been deleted, such as temporary breakpoints.
4379 infcmd.c (program_info): ditto.
4381 * core.c (core_file_command): Display the frame where the core
4386 * remote-vx.c (target_command): Merge in target command from

4389 * TODO, Projects: Lots more stuff to do...
4391 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
4393 Massive changes to wall off the remote-debugging interface
4394 behind a function vector. The port to handle VxWorks targets
4395 is also part of this.
4397 All files: Replace references to renamed functions,
4398 remove references to remote_debugging, remove references to
4399 have_include_file, have_core_file in favor of target_has_stack,
4400 target_has_memory, etc.
4402 * Modularize the breakpoint interface.
4403 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
4404 a breakpoint instruction.
4405 breakpoint.c: struct breakpoint's shadow_contents now sized as
4407 (insert_breakpoints): Vector to target to install breakpoints.
4408 (remove_breakpoints): Vector to target here too.
4409 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
4410 sparc-tdep.c (single_step): Use new breakpoint interface for
4411 the single-step breakpoints.
4412 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
4413 New file, contains routines to insert and remove breakpoints by
4414 reading out the old contents and later replacing them. This is
4415 how ptrace breakpoints work, and many remote systems as well.
4417 * tm-vxworks68.h: New config file, overrides a few things for
4418 Wind River's preferences.
4420 * target.h: New file, for transfer vector used to talk to the
4421 inferior (child, attached, core, exec, remote, etc). All accesses
4422 to the thing being debugged should come through these vectors.
4423 target.c: New file, routines to handle transfer vector.
4424 (various files): Add transfer vectors XXX_ops for the various
4425 targets and pseudo-targets (core files, etc) we support.
4427 * breakpoint.c (bpstat_stop_status): Further explorations of
4428 watchpoints and why things don't work all the time.
4429 (bpstat_alloc): New fn to allocate a bpstat and chain it.
4431 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
4432 the local gdbinit if it doesn't already have it.
4434 * core.c (core_ops): add and install.
4435 Allow core debugging without exec file.
4437 * dbxread.c (free_and_init_header_files): Merge two fns.
4438 (end_symtab): Free named symbol table when a new version comes in.
4439 (read_dbx_symtab): Relocate all kinds of symbols with base
4440 address. First step toward handling different text, data, bss
4442 (add_file_addr_command): Renamed add_file_command.
4443 (add_file_command): Vector to remote handler.
4444 Add "load" as an alias for "add-file" command.
4446 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
4447 non-returning functions.
4449 * exec.c: Add exec_ops, and push it as a target when an exec
4452 * infcmd.c (run_command): Pass executable file name and arg list
4453 separately when starting an inferior. Permit "run" when no exec
4454 file is specified, for VxWorks.
4455 (detach_command): Move to child_detach in inftarg.c.
4457 * inftarg.c: New file. Unix-child-specific routines, and the
4458 child_ops structure.
4460 * inferior.h (registers): Export "registers" as the way for
4461 target dependent register handlers to find gdb's local copy of
4462 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
4463 since it is now used by places that want wait_for_inferior to
4464 handle the grunge but want to see every trap from the inferior.
4466 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
4467 Eliminate remote_debugging hooks in terminal handling.
4469 * infrun.c: Replace start_inferior with child_create_inferior.
4470 Move all the hair of Unix shells and ptrace idiosyncracies into
4471 child_create_inferior, so remote handlers don't have to deal.
4472 Remove running_in_shell. Rename stop_after_attach to
4473 stop_soon_quietly, and use it in a few other places where we want
4474 to just call wait_for_inferior and get control back on the first
4475 trap. trap_expected now never takes a value > 1.
4476 (init_wait_for_inferior): Initialize static vars when a new
4479 main.c (gdbinit): Add new hook for .gdbinit file name, let
4480 it be overridden by config files as GDBINIT_FILENAME.
4481 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
4482 Both of these are used for VxWorks gdb.
4484 mcheck.c: rename include file "gmalloc.c" to avoid problems
4485 with system include file "malloc.c".
4487 param-no-tm.h: New include file, same as param.h but does not
4488 include the default "tm.h" file. This is used in files where
4489 the target is known, e.g. remote-eb.c or sparc-xdep.c.
4491 param.h: Now just a shell that includes tm.h and param-no-tm.h.
4493 remote-vx.c: New file, VxWorks remote debugging support. Uses
4494 RPC routines that are shared with the target system, in directory
4497 remote.c: Vectorize remote interface.
4499 source.c: Globalize source_path, and make an alias "l" for "list"
4500 since we now have the "load" command.
4502 sparc-xdep.c: Use new param-no-tm.h.
4504 symmisc.c (free_named_symtab): Add new function from Wind River.
4505 However, ifdef it out for now while we think about what it should
4508 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
4510 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
4511 non-Unix-children handle this with their own code in the target
4514 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
4515 source and target lists. Add vx-share to default list of include
4516 directories. Add new files to src and target lists: mem-break,
4517 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
4518 ${srcdir} versions of munch and createtags are used.
4520 * valops.c (find_function_addr): Split out of call_function.
4521 (call_function_by_hand): Rename call_function; this function
4522 calls functions in the target by laboriously patching the target
4523 word-by-word with the right stack, args, regs, etc.
4526 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
4528 Handle AMD 29000 a bit better.
4530 * remote-eb.c (readchar): Mask received char log to make it readable.
4531 (remote_start): Pass arguments down to executing program.
4532 Make startaddr unsigned.
4533 infrun.c (start_inferior): Accept args, pass them to
4535 infcmd.c (run_command): Pass args down to start_inferior.
4537 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
4538 the target object file format.
4539 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
4541 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
4542 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
4544 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
4546 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
4547 * TODO: We did a few things, we have more to do though.

4550 * inflow.c (inferior_died): Clear deferred stores.
4552 * Debug problems with dummy frames and calls to the inferior.
4553 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
4554 * sparc-tdep.c (do_restore_insn): Simplify.
4555 (sparc_frame_find_saved_regs): Simplify and fix what we find.
4556 (sparc_push_dummy_frame): Simplify and fix what we push.
4557 (sparc_pop_frame): Slightly more hair here, deciding whether
4558 we are restoring a saved PC or returning to a return address in %i7.
4559 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
4561 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
4562 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
4563 * obstack.h (chunkfun): ditto.
4564 * defs.h (xmalloc, xrealloc): ditto
4566 * utils.c (quit): Grab the terminal from the child if necessary.
4568 * inflow.c (term_status_command): Rename to term_info, change
4571 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
4572 (is_delayed_branch): Speed up.
4573 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
4574 Still missing some float ops, and needs testing.
4576 * Support for input and output radixes other than base 10
4577 * defs.h (input_radix, output_radix): Declare.
4578 * expread.y (yyparse, parse_number): Handle changes of input
4579 radix, and ambiguous names-or-numbers in radixes >10.
4580 * printcmd.c (print_scalar_formatted): Print formatted hex
4581 numbers in varying column widths.
4582 * valprint.c (val_print): Use output_format to print scalar ints.
4583 (set_input_radix, set_output_radix, set_radix): Create.
4584 (set_output_radix): Set output_format from output_radix.
4585 (_initialize_valprint): add `set radix' but leave the others off.
4587 * main.c (execute_command): Let stupid questions be turned off.
4588 (_initialize_main): Handle "set stupidity", etc.
4590 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
4591 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
4593 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
4595 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
4596 bfd stuff is still screwed up, but with some manual work, it
4599 * breakpoint.c (bpstat_do_actions): Start over if a command
4600 proceeds the inferior, since the inferior will have stopped and
4601 will need to have its new stop-actions taken care of.
4603 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
4604 compiler fits, simplify it.
4606 * gdb.texinfo (directory command): Doc new dir command.
4607 source.c (directory_command): "dir" now puts things on the front
4608 of the path, moves dups up front, and handles multiple names
4609 on the command line, inserting each one in order. It also
4610 blows away cached line and full_filename info.
4612 * stack.c (backtrace_command): Skip "more stack frames follow"
4615 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
4616 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
4617 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
4618 The only odd one was Gould NP1, which had defined vprintf to
4621 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
4622 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
4623 variable, inspect_it.
4624 valprint.c (print_string, val_print): Use the global inspect_it
4625 to indicate whether to print in Epoch style or normal style.
4627 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
4629 * printcmd.c (call_command): add an alias for the "print" command
4630 which runs expressions and doesn't print the result if void.
4631 (print_command_1): implement it.
4633 * command.c: Remove #if 0'd code. Initialize all the fields
4634 in add_cmd (). Rename do_nothing_command to
4635 not_just_help_class_command, and make it externally visible.
4636 command.h: add user_commands to struct.
4637 * main.c (define_command): Don't overload c->function with a char
4638 string as well as a function pointer.
4640 * eval.c (evaluate_subexp): Reinstall tiemann changes to
4641 calling convention of value_struct_elt () that got dropped in
4644 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
4645 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
4647 * tm-sparc.h (POP_FRAME): replace some constants with defines.
4649 * sparc-xdep.c (store_inferior_registers): defer stores to regs
4650 until a good time (e.g. when we are about to run the child),
4651 saving ptrace calls.
4652 * infrun.c (proceed): handle DO_DEFERRED_STORES.
4653 * tm-sparc.h: define DO_DEFERRED_STORES.
4655 * sparc-xdep.c (store_inferior_registers): when storing float
4656 registers, don't store stack regs too. When storing the SP,
4657 however, DO store the stack regs too. This fixes a bug in which
4658 the dummy frame is not recognized when a call_function finishes,
4659 because its frame pointer (in the stack regs) was never
4661 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
4662 even though we don't know how to read them from an inferior.
4663 valops.c (call_function): Comment about storing SP.
4665 * infrun.c (save_inferior_status): Save away the original bpstat
4666 chain so it can be restored later. Install the copied version for
4667 use by whoever saved the status. It will be blow away by
4668 restore_inferior_status, and the original chain restored. This is
4669 important for people who have pointers into the original.
4671 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
4672 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
4673 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
4676 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
4678 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
4679 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
4680 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
4682 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
4684 * Merge Mike Tiemann's multiple inheritance changes from Sun.
4685 Store the baseclasses in a type struct starting from array element
4686 0 rather than from the unusual array element 1.
4688 dbxread.c: the above.
4689 (virtual_context): Add
4690 Read new debug information about which virtual function table
4691 a virtual function is from, and store it in fn_field.fcontext.
4693 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
4694 TYPE_FN_FIELD_STATIC_P.
4696 symtab.c: the above.
4697 valops.c: the above. Handle pointer casts of object *'s.
4698 (search_struct_method): Add.
4699 (value_struct_elt): First arg is now a pointer to a value, and is
4702 valprint.c: the above.
4703 values.c (value_virtual_fn_field): Add type arg. Handle
4704 offsetting to the proper object when calling virtual fns.
4706 (baseclass_addr): Add valuep arg.
4708 * README: Document the current state of BFD config (missing).
4709 * TODO, ChangeLog, Makefile.dist: Roll version.
4710 * WHATS.NEW: Add summary of changes since 3.5.
4712 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
4714 * dbxread.c (read_struct_type): Clear bit vectors whenever
4716 symtab.c (B_CLRALL): define.
4718 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
4719 using == rather than =. Huh... This fixes the dreaded problem
4720 wherein builtin_type_int becomes TYPE_CODE_FLT.
4722 * core.c (info_files): Show the inferior pid.
4724 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
4725 already knows how to look in the source directory.
4727 * Remove psymtab hair from many places. Remove duplicated code
4728 for searching symbol tables. Hide psymtabs from most places.
4729 Make it fast to get from a psymtab to its symtab.
4731 blockframe.c (blockvector_for_pc): Remove psymtab hair.
4732 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4733 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4734 dbxread.c: export psymtab_to_symtab, make it work if called N times.
4735 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
4736 new symtab completely. New psymtabs get symtab pointer
4737 initialized to zero. Remove MI warning printf.
4738 symtab.h: Comments. Add psymtab to symtab pointer.
4739 (PSYMTAB_TO_SYMTAB): New macro.
4740 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
4741 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
4743 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
4745 (print_frame_info): Avoid special-casing symbols that have not yet
4748 * source.c (open_source_file): Quick path if we have already
4749 located the source file by its full name.
4751 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
4752 find_pc_psymtab. When a name is found in the misc function
4753 vector, search the symbol table for its mangled name, not the
4754 name that the user typed.
4756 * bfd.h: Fix missing comment terminators, make #endifs match.
4758 * valarith.c (value_less): Handle unsigned int comparisons.
4759 Add FIXME about pointer compares, which assume host and target
4760 pointers are the same.
4762 * command.c (do_nothing_command): lint
4763 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
4764 fix comments on debug symbol format for visibility. Actually set
4765 visibility of symbols.
4766 main.c (echo_command): lint; use <readline/history.h>.
4767 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
4768 obstack.h (_obstack_blank): Rearrange pointer math to avoid
4769 pointing past end of allocated memory; saber complains.
4770 obstack.h: Declare the external functions that we use.
4771 valarith.h: use <string.h>
4772 solib.c (solib_add): lint.
4774 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
4776 * main.c (initialize_main): Default info_verbose to off, now that
4777 symbol reading is fast.
4778 (quit_command): Avoid clobbering exec_bfd while quitting.
4780 * Initial BFD (binary file diddling library) merger:
4781 coffread.c: Change AOUTHDR to struct exe_hdr.
4783 core.c: initialize initialized data at compile time.
4784 (core_file_command): Move from coredep.c, convert to bfd.
4785 (xfer_core_file): Convert to bfd.
4786 exec.c (exec_file_command): use bfd routines.
4788 mips-tdep.c: Remove exec_file_command and friends.
4791 * coredep.c: (fetch_core_registers) Convert core_file_command to
4792 fetch_core_registers.
4793 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
4795 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
4796 (my_bfd_read): More bogosity, which I don't think we call.
4797 (program_name): Remove this atrocity asap!
4799 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
4802 values.c: allocate_repeat_value was not clearing the
4803 optimized_out field.
4804 (value_static_field): minor stylistic fix (wrong macro was used).
4805 valops.c (value_struct_elt_for_address): didn't work for C++
4808 * signame.c (_initialize_signame): Initialize signal names once.
4810 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
4811 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
4812 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
4814 * remote-eb.c: Support user-settable baud rates on the serial port.
4816 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
4818 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
4820 * tconfig/sun3os4: Remove warning about native assembler,
4821 since it also occurs in the xconfig file.
4823 * findvar.c (registers): Allocate some slop after `registers'
4824 to prevent stray accesses from trashing the next variable.
4826 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
4827 on the sun-3, by changing the #ifdef from `sun3' (which is not
4828 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
4829 vars, which happened to follow `registers' in the executable.
4831 * readline/history.c (history_search): Heed gcc-2's advice
4832 and parenthesize && inside ||).
4834 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
4835 tm-29k.c: Insert FSF copyright headers.
4837 * remote-eb.c: Better comments.
4839 * Makefile.dist: Update to 3.91.6.
4840 * TODO: note PREPARE_TO_STORE problem.
4842 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
4844 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
4846 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
4848 * infrun.c (wait_for_inferior, at end): Don't set up
4849 prev_* if the inferior no longer exists.
4851 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
4852 CANNOT_EXECUTE_STACK.
4853 valops.c (call_function): Use it.
4855 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
4857 * inferior.h (PC_IN_CALL_DUMMY): New macro.
4858 infrun.c (wait_for_inferior, 2 places): Use it.
4860 * values.c (value_being_returned): Only use
4861 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
4863 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
4864 right thing for remote-eb.c.
4866 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
4867 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
4869 * blockframe.c: Put get_frame_saved_regs inside #if !defined
4870 (FRAME_FIND_SAVED_REGS).
4872 * findvar.c ({fetch,store}_registers): Check for
4873 REMOTE_{FETCH_STORE}_REGISTER macro.
4875 * findvar.c (get_saved_register): Add argument lval and
4876 change meaning of argument addr.
4877 findvar.c: Change calls to get_saved_register to reflect
4878 new calling convention.
4879 valops.c (value_assign): Use get_saved_register instead of
4880 find_saved_register.
4882 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
4884 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
4885 an (uninitialized) pointer to one. Use "&" when passing it
4888 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
4890 * coffread.c (getfilename): Use DGUX x_offset and x_name if
4893 * coffread.c (symbol_file_command): Put semicolon after
4895 Put safe_to_init_tdesc_context in #if defined (TDESC).
4896 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
4897 coffread.c: #include <sys/stat.h>.
4898 (read_coff_symtab): Typo: in_source_files -> in_source_file.
4899 Add missing ')' in check for "lc%" and friends. Remove
4901 Declare read_one_sym() at top of file.
4902 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
4903 MC68WRMAGIC can have the same value without causing a duplicate
4906 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
4908 * Allow a Makefile to be built without building the
4909 tm and xm file links that screw up builds in subdirectories.
4910 This is done with `config.gdb none', then you can do things
4911 like `make gdb.tar.Z'.
4912 * tconfig/none: Config file for no target system
4913 * xconfig/none: Config file for no host system
4914 * config.gdb: If no TM or XM files are called out by the
4915 host or target file, don't make links for them.
4917 * cplus-dem.c: Add documentation.
4919 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
4920 simple error, so the user's gdb doesn't crash due to some object
4921 file problem (e.g. somebody is rebuilding the file out from under
4924 * printcmd.c (print_address_symbolic): demangle the symbol.
4926 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
4927 Motorola copyrights in it. Make "make gdb.tar.Z" work.
4928 (alldeps.mak): sort and uniq all results from this; duplicates
4929 hose gdb.tar.Z link building. Remove RCS files from
4930 tconfig and xconfig. Add config files for sun386. Add
4931 a few odd files to OTHERS and HFILES.
4933 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
4935 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
4936 Roll version number to 3.91.5. Make lint work in bindir.
4938 * README: Document cross-debugging and new file structure.
4940 * blockframe.c: Lint. Include "value.h" to declare read_register.
4941 (find_pc_partial_function): remove duplicate line.
4943 * command.h: Lint. Declare error_no_arg and dont_repeat.
4945 * tm-news.h: Remove inadvertently duplicated stuff.
4947 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
4948 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
4950 * config.gdb: Allow `config.gdb host target' form. Clean
4951 up previous change that printed bogus messages when you just said
4954 * core.c: #include "command.h" for lint.
4957 * main.c: Remove some casts of enums. Lint.
4964 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
4966 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
4967 read it from memory. This will allow us to save ptrace calls
4968 eventually. Changed caller single_step too.
4970 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
4971 that we aren't going to use, saving many ptrace calls, especially
4972 when watchpointing or single stepping. Use some #define's for
4974 (store_inferior_registers): Ditto.
4975 (core_file_command): Use some #define's for constants.
4977 * tm-sparc.h: Add #define's for some register numbers, so we
4978 can eliminate the use of random constants in sparc-xdep.c.
4980 * stack.c (frame_command, print_frame_info, up_command,
4981 down_command) Remove frame_changed, since it
4982 causes a bug and doesn't seem to do anything useful. In some
4983 places it was used as a flag, in others as a stack level (?).
4985 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
4986 default is to use the portable (vprintf) version rather than the
4988 * xm-news.h (MISSING_VPRINTF): Add.
4990 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
4992 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
4994 * Remove stuff that forces -Bstatic linking of gdb, and warnings
4995 about linking debugged programs -Bstatic in the sun?os4 config
4996 files in tconfig and xconfig subdirectories.
4998 * main.c (main): Remove unreached exit(0) now that we exit
5001 * Create TODO file for online bug list. There are too many
5002 "little" bugs to keep track of on paper.
5004 * Change Projects file to refer to bug-gdb@cygnus.com
5005 rather than kingdon@ai.
5007 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
5009 * Makefile.dist (VERSION): 3.91.4 now.
5011 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
5012 (condense_misc_bunches): Add sanity check that misc_count is
5013 the same as the number of symbols in the bunch.
5015 * coffread.c: rename init_misc_bunches. Pass an argument
5016 to condense_misc_bunches (a zero).
5018 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
5019 every time we are called; don't rely on our caller to do it.
5020 (add_file): Remove call to init_misc_bunches.
5022 * mipsread.c: Only warn, don't error, if unknown symbol types.
5023 This keeps an old gdb from falling on its face if it sees newly
5024 extended symbol info. Rename init_misc_bunches.
5026 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
5028 * Merge in changes from Per Bothner for DECstations and other
5029 MIPS stuff. The rest is Bothner speaking:
5031 The next message is a merger of Alessando Forin's mips port with
5032 mine. I've tried to use my good if biased judgment to get
5033 the best of both. It *does* need testing.
5035 Some of the changes are general, *not* mips-specific.
5038 Didn't believe in little-endian bit order.
5039 There are still inconsistencies about whether flags
5040 like BITS_BIG_ENDIAN are integer (#if ...) or
5041 boolean (#ifdef ...). I tried to paper over them.
5043 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
5044 Moved some misc_function code that was common to
5045 {dbx,coff,mips}read.c to symtab.c.
5046 In the process, I think I cleaned things up a bit.
5047 At the same time, moved obsavestring and obconcat to symtab.c.
5050 Removed obsolete condense_addl_misc_bunches (use
5051 condense_misc_bunches(1) instead).
5054 Needed to include <sys/dir>, at least on DECstations.
5056 valops.c, mips-tdep.c, tm-mips.h:
5057 Added PUSH_ARGUMENTS macro to support funny argument-pushing
5058 conventions (when STACK_ALIGN is insufficient).
5059 Needed on mips, where doubles need 8-byte alignment,
5060 but ints only need 4.
5063 Removed cruft that was not being used.
5064 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
5067 Print $ before register-names (I think that makes things a little
5069 Never print two instructions, even if one delays.
5070 Removed hex-disassemble set_cmd. (This is not mips-specific,
5071 so I think the argument is whether it is generally worthwhile or not.
5072 I'm inclined to think not, given how easy it is to
5073 convert between radixes in gdb.)
5076 This is basically Alessando's code.
5077 It doesn't use obstacks; I changed it to use obstacks
5078 in a few minor places where using malloc causes a
5079 memory leak. (Probably, more places could/should be changed.)
5080 I added record_misc_function where it was missing.
5081 In symbol_file_command and add_file_command, I tried
5082 to make the code consistent with more recent versions.
5083 Minor sylistic changes in parse_procedure.
5084 Make a .gdbinfo. psuedo-symbol point back to the real
5085 procedure symbol (using the isym field).
5088 This is basically from my port, but with a lot of details
5089 and a number of routines merged in from Alessando's version.
5090 I basically used my code "raw" backtrace (use heuristics
5091 from the actual code, rather than symbol table info) - though
5092 the idea is Alessandro's. I feel my code is a little cleaner
5093 here, particularly in being a little more flexible, such as being
5094 able to handle gcc-produced code (which it now can).
5095 It also doesn't do frame caching (which is not useful
5096 more recent gdb versions).
5097 I also used my code for push_/pop_dummy, more or less.
5098 I tried to incorporate AF's code for testing sigtramp
5099 while backtracing; I probably got it wrong.
5100 Added mips_print_register, which tries to scrunch as much
5101 information as possible on a screen...
5102 Removed the skip-prologue set_cmd. As with hex-disassemble (see
5103 under mips-pinsn.c), I don't see anything mips-specific here,
5104 and I don't see it being all that useful anyway.
5107 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
5108 Use more register names (rather than hard-cases numbers).
5110 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
5112 * Hack up 3.90.11 changes:
5114 * Makefile.dist (depend): parameterize $(GCC).
5115 Add solib.c and solib.o.
5116 (readline): Fix vpath for both absolute or relative SRCDIR.
5118 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
5119 Also, let the part I didn't understand at least compile so
5120 I can test the rest. FIXME.
5122 * dbxread.c: Fix thinko using strcmp.
5123 (init_psymbol_list): declare static.
5124 (partial_symbol_file_open): Comment cleanups better, avoid
5125 cleaning up the string table since the caller will do that.
5126 Move the stat for mod time into symbol_file_command, temporarily.
5127 (There should be a mod time for each symbol file, eventually,
5128 to control its rereading. FIXME.)
5130 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
5131 SunOS, which gives error for shared libs otherwise. (From
5132 Schaefer, probably FIXME needs work for portability.)
5134 * solib.c: Move #include "param.h" to work.
5135 Lowercase all the Uppercase Letters In the Messages.
5136 (find_solib): Clean up inferior_so_name for debug printouts.
5137 Allow no argument, to mean all shared libraries.
5139 * symmisc.c: include param.h to get CLEAR_SOLIB.
5141 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
5143 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
5144 to 3.90.11. ChangeLog entries below are from this.
5146 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5150 * Makefile.dist (HFILES): Add tm-sunos.h.
5152 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5156 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
5158 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
5160 * sparc-opcode.h Added single-operand version of rett.
5162 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5164 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
5165 Put parens around gcc_p in expansion.
5167 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5169 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
5171 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5173 * Changes for Sun shared libraries:
5174 blockframe.c (find_pc_partial_function): If a non-text symbol
5175 is found, set *address = pc - FUNCTION_START_OFFSET.
5176 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
5177 Disable breakpoints instead of giving an error.
5178 source.c (select_source_symtab): Initialize cs_pst.
5179 symmisc.c: Call CLEAR_SOLIB if defined.
5180 symtab.h: Make text{low,high} CORE_ADDR not int.
5181 (psymtab): New field addr.
5183 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
5184 (record_misc_function): Give correct type for N_DATA symbols.
5185 (condense_misc_bunches): do "misc_function_count = j" regardless
5187 Take code which is shared between symbol_file_command and
5188 add_file_command and put it into partial_symbol_file_{open,read}.
5189 Split add_file_command into add_file_command and add_file.
5190 Make psymtab_to_symtab read in the string table if the file
5192 Two new parameters to read_dbx_symtab and start_psymtab.
5193 tm-sunos.h: New file.
5195 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5197 * infcmd.c: Change cont_command to continue_command and "cont"
5200 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5202 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
5204 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
5206 * values.c (USE_STRUCT_CONVENTION): Check for structures of
5207 size 1,2,4,8 rather than size < 8.
5209 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
5210 as necessary, not just once.
5212 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
5214 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5216 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
5218 * tm-news.h: Add CALL_DUMMY_*.
5220 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
5222 * config.gdb: In list_host, list_target, use ${i}, not $i.
5224 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5226 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
5228 * sparc-opcode.h: Change all store floating-point state register
5229 instructions to have the right match & lose fields.
5231 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5233 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
5235 config.gdb: If srcdir != ., create readline directory and
5236 copy a makefile into it.
5238 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
5239 consistency with POSIX.
5241 * breakpoint.c (bpstat_stop_status): Disable watchpoint
5242 when we exit its exp_valid_block.
5244 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
5246 * Makefile.dist: Bump version to 3.91.3.
5248 * Clean up handling of breakpoint commands (somewhat).
5249 Prompted by Tiemann bug report "cont 10" doesn't work any more.
5251 inferior.h: Add breakpoint_proceeded to inferior status struct
5252 and globals; save it and restore it.
5253 (clear_breakpoint_commands): Cleanup, remove old #define.
5255 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
5256 (save_inferior_status, restore_inferior_status): handle it also.
5257 (proceed): Remove earlier code that set breakpoint_proceeded.
5258 It is now set only in clear_proceed_status.
5259 (clear_proceed_status): Cleanup, use bpstat_clear rather
5260 than clear_breakpoint_commands. No callers need the stop_bpstat
5261 between clear_proceed_status and proceed.
5263 infcmd.c: Add breakpoint_proceeded definition and comment.
5264 (cont_command, jump_command, signal_command): Move call to
5265 clear_proceed_status right next to call to proceed.
5267 breakpoint.c (bpstat_do_actions): Avoid clobbering our
5268 caller's argument while running down the chain of breakpoints.
5269 Use new variable "breakpoint_proceeded" to determine when
5270 a command that it executes moves the inferior past the
5272 (bpstat_clear): Handle NULL argument.
5273 (bpstat_clear_actions): Avoid useless call to
5274 breakpoint_auto_delete.
5275 (delete_breakpoint): Clean up bpstat's that are pointing to
5276 the deleted breakpoint from the stop_bpstat chain.
5277 (breakpoint_auto_delete): Simplify.
5279 * Clean up handling of EOF, error on stdin, etc. This was
5280 prompted by a network problem that caused gdb to go into an
5281 infinite loop filling up its malloc'd memory.
5283 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
5284 not clear_breakpoints_commands, which is now gone.
5285 (main): If command_loop returns (e.g. from EOF on stdin), do
5286 a quit_command (looping back to command_loop if quit_command
5287 doesn't really quit).
5288 (command_loop): check result from command_line_input and
5289 exit if it returns NULL, rather than passing the NULL to
5291 (gdb_readline): Free malloc'd result space before returning
5294 * utils.c (query): Handle C-d to mean "yes", just as if the
5295 input was not a terminal. Also avoid infinite loop if EOF
5296 occurs in mid-input-line before newline. This allows
5297 query to be used at EOF on stdin with reasonable results.
5299 * infrun.c (proceed): Set breakpoint_proceeded.
5301 * values.c (value_as_long): Avoid infinite recursion for enums.
5302 (_initialize_values): Fix typo in help msg (kingdon).
5304 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
5305 RL_LIB for linking. This allows -lreadline for linking
5306 and nothing for dependencies, once readline is a real library.
5308 * config.gdb: Jim Kingdon: give useful error message if the
5309 host or target type is not recognized.
5311 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
5312 it just defines it. Dumb, but deal with it.
5314 * Jim Kingdon suggests:
5315 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
5317 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
5319 * Makefile.dist (VERSION): Bump version # to 3.91.2.
5321 * Clean up Bothner's changes.
5323 * blockframe.c (clear_pc_function_cache): New function.
5324 * blockframe.c: remake cache_pc_function_* static.
5325 * dbxread.c (symbol_file_command): remove references to
5326 cache_pc_function_* variables.
5327 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
5328 * printcmd.c: Avoid kludging a global variable (addressprint)
5329 to avoid printing the address of a string twice. Instead,
5330 pass the format letter 's' down low enough that it can be seen
5331 to avoid this problem.
5332 (print_formatted): Pass format arg to value_print.
5333 (restore_addressprint): Remove function.
5334 (do_examine): Avoid hacking addressprint, cleanups and such.
5335 (print_frame_args): Add a comment to a Bothner change.
5336 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
5337 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
5338 to wipe out the values cached in blockframe.c.
5339 * symtab.c (find_method): Add comment saying how big you must
5340 allocate to be "big enough". Per being terse again.
5341 * valprint.c (val_print): Handle format letter "s" to print
5342 strings without addresses. Add comment to vtbl printing code
5343 which casts with wild abandon. Rearrange reference-printing
5345 @0xaddr: value (print w/addressprint)
5346 value (print w/~addressprint)
5347 @0xaddr (parameter lists w/addressprint)
5348 or nothing (parameter lists w/o addressprint)
5350 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
5352 * Merge more changes from Per Bothner:
5354 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
5355 annoying) that I tried to improve it. Here are my suggestions.
5357 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
5360 Do automatic de-reference when taking the address of a reference.
5362 Don't deref_ref when printing parameter lists.
5364 More attempts at treating refernences properly.
5366 In val_print, if deref_ref==0, don't print dangling " = ".
5368 Add COERCE_REF macro, which de-references an REF.
5370 * Merge changes from Per Bothner:
5372 * Fixed (Sony news)-specific configuration problems.
5373 * Fixed other problems with using vanilla pcc and libc (enum problems;
5374 assumption that vsprintf exists).
5375 * Some major speed-ups (finc_pc_partial_function now caches a match;
5376 parsing avoids duplicate symbol_lookup calls).
5377 * Changed handling of baseclasses (no longer use baseclasses field
5378 of struct type, use the first n_baseclasses fields instead).
5379 * Various minor changes/fixes, most C++-related.
5382 Cache the most previous match from find_pc_partial_function.
5383 (Save both low and high ends of matching function's pc range.)
5384 This speeds up the loop of infrun.c:wait_for_inferior quite
5385 a bit, and makes step/next commands much zippier.
5387 Added an enum->int cast (otherwise, some compilers barf).
5389 No longer set baseclass offset to 0, since multiple
5390 inheritance now mostly works.
5391 Added a number of casts, to shut up compiler warnings
5392 (after stabs where made enums, not ints).
5393 When discarding a symbol table (in symbol_file_command),
5394 must clear the cache introduced in blockframe.c.
5395 Don't convert $vtbl_ptr_type to vtbl any more.
5396 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
5397 Mask off sign bit emitted by g++ for virtual table offset.
5398 Set voffset to -1 (not 1) for static member functions.
5400 Changed parsing/lexing of names to avoid doing symbol lookup twice
5401 (once when lexing to determine symbol class, once for real).
5402 Now only call symbol_lookup once. Fields of 'this' win especially big.
5404 Subpress printing addr twice in the case of 'x/s addr'.
5406 lookup_basetype_type is no longer used.
5407 Add find_methods as recursive helper function to decode_line_1.
5408 This allows multiple inheritance to work.
5409 Also, once one or more matches has been found, do not look in
5410 base-classes. (Baseclass methods would be overridden, anyway.)
5412 Removed baseclasses array in struct type.
5413 Instead of using baseclasses[i], use fields[i-1].
5414 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
5415 Changed sign convention of voffset (previous was inconsistent).
5417 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
5419 Used to assume existence of vsprintf. Re-written to not need it
5420 if HAVE_VPRINTF is undefined.
5422 typecmp was too pessimistic. Made it less so.
5424 Don't print space after address.
5425 If vtable points to a misc symbol (with 0 offset), print it,
5426 since that indicates the actual class of the object.
5427 Changed ype_print_derivation_info to use new inheritance
5428 scheme (without baseclasses vector).
5430 In value_primitive_field, fixed some bugs left over from previous set of fixes.
5431 Also, changes needed because TYPE_BASECLASSES were removed.
5433 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
5435 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
5438 If there is no path set, and the symbols don't indicate what directory
5439 a file was compiled in, look in the current directory. But either
5440 a path or a known compilation directory will prevent this.
5443 Three independent bug fixes:
5444 * Remove the #if 0 block that breaks some stuff.
5445 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
5446 adapt gdb to either SunOS 4.0.* or 4.1.
5447 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
5450 Instantiate the class T when looking for methods in it. (Tiemann@sun)
5453 (type_print) Demangle the name being printed.
5454 (type_print_base) Handle botched demangling without coredump (tiemann).
5457 (check_stub_method): Document routine.
5458 (tiemann) fix bug for no-arg functions
5459 Avoid clobbering beyond end of malloc'd storage.
5460 Terminate the argument list properly.
5462 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
5464 * Changes merged by John Gilmore:
5467 In breakpoint_1, use new print_address_symbolic instead
5468 of find_pc_partial_function. (This forces use of assembler-level
5469 addresses, and avoids misleading non-mangled source-level names.)
5471 Generalize ansi argument such that -1 means skip arglist totally.
5472 Removed global variable print_ansi_qualifiers (which made
5473 code non-reentrant), in favor of extra explicit arguments
5474 to internal routines.
5476 Add new helper function print_address_symbolic.
5477 Use find_pc_misc_function instead of find_pc_partial_function
5478 (since we want assembler-level symbols here).
5480 Print unknown function as just "f (...)", not "f (...) (...)".
5481 Use new fputs_demangled explicitly.
5483 Fixed a typing violation (problem: value.h cannot be imported
5484 without renaming many variable in this file).
5485 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
5486 decode_line_1: Moved forward some never-reached code.
5487 Made decode_line_2 skip function prologues correctly.
5489 fputs_filtered should not demangle by default.
5490 Add new fputs_demangled to demangle on demand..
5492 Change value_struct_elt to use value_primitive_field (using recursive
5493 utility function search_struct_field). This allows foo.bar to work
5494 for multiple inheritance (so far only for data fields).
5495 Change check_field in the same way (recursive helper function
5496 to support multiple inheritance).
5497 (Note: there are more of these problems that I haven't fixed.
5498 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
5499 value_of_this: 'this' symbol name is now just "this", note "$this".
5501 Don't print static members.
5502 Avoid printing "members of <type>" if there are none.
5503 Simplified type_print_derivation_info by merging duplicate code.
5504 Remove useless blank lines in type_print_base (ptype command).
5506 Added declaration of new routine value_primitive_field.
5508 Added value_primitive_field which is generalized version of
5509 value_field that can handle multiple inheritance (non-zero offsets etc).
5510 Re-implemented value_field to call value_primitive_field.
5512 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
5514 * infcmd.c -- insert else to avoid 'delete env' coredump when you
5515 delete the whole environment. Karl Berry reported the bug.
5516 * source.c - fix openp to avoid //'s in filenames, which
5517 trigger an Emacs bug causing it to not be able to find files
5518 when running gdb in a window.
5519 * dbxread.c - zap the #if 0 that botches the add-file code.
5520 It seems to work a lot better without all the code commented out.

5524 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
5527 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
5529 * Makefile - added a ${CFLAGS} to a couple of entries,
5530 added remote-sa.sparc.c
5531 * added remote.sa-sparc.c, a modification of remote.c
5532 which conducts a dialog directly with the SparcStation prom.
5533 * breakpoint.c, infrun.c, sparcdep.c added
5534 remote_insert_breakpoint(), and remote_remove_breakpoint()
5535 to breakpoint.c instead of directly writing breakpoint instructions.
5536 * sparcdep.c on remote_debugging,there is no need
5537 to remove signle step breakpoint instructions.
5538 * main.c added "-epoch" flag and "int epoch_interface" to main.c
5540 * printcmd.c - epoch interface sends lisp expressions to open up
5541 epoch windows on inspection.
5542 * valprint.c - added arrayprint, and addressprint and made adding
5543 format controls easier
5544 * wait.h added a couple of undef's because we were getting
5545 complaints about WSTOPSIG and WTERMSIG begin redefined.
