126 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
128 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
129 entries are enclosed herein:
131 Mon Jun 3 17:05:45 EDT 1991
133 m2-exp.y Created. Tested outside of GDB for a few days. Proper
134 operators were added, C specific operators and tokens
135 removed. yylex() revamped to some extent. Still things
136 missing from the grammar, such as sets.
137 Tested for two weeks in GDB v3.5.
139 Tue Jun 11 17:23:48 EDT 1991
141 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
142 so they are built-in. Sort of a hack.
144 Fri Jun 14 12:53:51 EDT 1991
146 m2-exp.y Added range checking for numeric constants. Any numeric
147 constant is assumed to be of builtin type INTEGER unless:
148 (1) it is octal or hexadecimal, in which case it is a
149 CARDINAL; (2) it is too big to fit into an INTEGER, in
150 which case it is a CARDINAL.
151 eval.c Added simple range checking for +, -, and * on integers.
152 Doesn't work very well for *, since 6 * 1,000,000,000 =
153 1,705,032,704, which fails the simple test of result >=
154 first_operand, no matter in what order the operands are.
156 Tue Jun 18 14:11:30 EDT 1991
158 Broke the parser into parts, one containing the C grammar and the other
159 containing code to be shared by all of the grammars.
161 The following files no longer exist:
166 The following files were added:
168 c-exp.y (The C grammar)
169 m2-exp.y (The Modula-2 grammar)
170 parser-code.c (Code that is shared by the above grammar)
174 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
175 now necessary to use the Bison compiler compiler, since it
176 will generate function/variable prefixes other than yy.
178 Tue Jun 18 16:47:49 EDT 1991
180 symtab.[ch] Added the external variable working_lang, than holds the
181 value of the current working language.
182 Added the ennumerated type language_mode, with the values
183 language_auto and language_manual, the former meaning that
184 GDB sets working_lang as needed, and the latter meaning
185 that the value of working_lang is totally under user
187 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
188 REAL, BOOLEAN and CHAR. Also added the type codes
189 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
190 utils.c Added set_language_command and show_language_command to
191 implement the GDB support commands "set language" and
193 expression.h A number of identifiers were added to the type exp_opcode
194 to facilitate Modula-2 builtin functions, integer
195 division, and array indexing.
197 Wed Jun 19 13:25:58 EDT 1991
199 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
200 if the language specified by working_lang requires the use
201 of strict typing of expressions. Eventually, even this
202 will be able to be changed by the user.
203 Added the macro RANGE_CHECK, which evaluates to non-zero
204 if the language specified by working_lang requires the
205 checking of a value against the domain of its type.
206 Eventually, even this will be able to be changed by the
208 language.[ch] Predicates involving types (simple_type, ordered_type,
209 same_type, integral_type, numeric_type, character_type,
210 boolean_type, float_type) are added. These predicates are
211 based on the current value of working_lang, and are handy
214 Wed Jun 19 15:39:34 EDT 1991
216 eval.c Added the function type_array_rank which computes the rank
218 valarith.c Added the funtion value_bool, which when given a integer
219 value.h value (ie. struct value *) as an argument, it returns a
220 boolean value (ie. struct value *) true if that integer
221 is non-zero, and a boolean value false otherwise.
222 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
223 will print out properly.
225 Wed Jun 19 16:36:34 EDT 1991
227 valops.c Added the function value_capitalize, which returns it
228 value.h argument capitalized if its argument is a lowercase
229 letter, or the argument unchanged if its argument is not a
231 valarith.c Added the function range_check_p, which returns non-zero
232 value.h if its value argument is between the integral bounds upper
234 Added the function range_check_enum_p, which makes sure
235 that its value argument is a valid member of the domain of
237 Added the function range_check_range_p, which makes sure
238 its value argument lies between the upper and lower bounds
239 of its type argument, which must be a ranged type.
240 Added the function check_array_index, which range and type
241 checks an index of an array.
242 Added the function value_multi_subscript, which computes
243 array[idx1,idx2...idxN], given a value array and an array
244 of values representing indicies.
245 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
246 unpack_long to work with TYPE_CODE_BOOL and
249 Wed Jun 19 18:04:08 EDT 1991
251 symtab.c Stored pervasive types in a structure and make
252 lookup_pervasive_type() a lookup function that was based
253 on working_lang. If lookup_pervasive_type() returned
254 non-zero, then that value was returned (a fix, since
255 before it simply wouldn't return the pervasive type.)
256 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
257 non-zero if the language specified by working_lang means
258 "conversion" when it says "cast".
259 valops.c Added the function value_real_cast(), which performs a
260 value.h *cast*, not a *conversion*, which is what value_cast()
261 does when it can. In particular,
262 value_cast(<float_type>,4) = 4.0, while
263 value_real_cast(<float_type>,4) = some mess.
264 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
265 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
266 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
267 and MIN on integral types. *NOTE*: These are currently
268 hardcoded to work only if there are 8 bits per storage
270 eval.c Made logical functions call value_bool to return a
271 properly typed boolean value, based on working_lang.
273 Thu Jun 20 11:55:27 EDT 1991
275 valprint.c Types now print out in a Modula-2 fashion. This works for
276 the cases when the type is printed out step-by-step, that
277 is, it doesn't work when the name of a structured type
278 (which includes the keyword "struct", etc.) is simply
280 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
281 since type specifications in C and Modula-2 are very
282 different. The C printing of a type is very recursive,
283 whereas in Modula-2 it is generally very simple. C has
284 type prefixes and suffixes, which have no real analogue in
285 Modula-2. Maybe type_print() should call a language
286 specific type printer. This is also advantageous if we
287 compile GDB to exclude some of the languages. We'll just
288 leave those functions out.
290 Thu Jun 20 16:57:10 EDT 1991
292 dbxread.c When reading the complete symbol table in (via
293 psymtab_to_symtab()), the number and types of function
294 arguments are added to a function type. define_symbol()
295 calls add_param_to_type() to accomplish this.
296 Assumption: when we come across a function definition
297 (N_FUN symbol with an 'f' or 'F' in the name), its
298 arguments will appear before another function definition.
299 When a function is found, a pointer to its type is placed
300 in the global in_function_type. Changes that
301 add_param_to_type() makes are to this global.
302 valprint.c The type of a function now includes (for Modula-2) the
303 types of its parameters.
304 eval.c Type checking and a check for the proper number of
305 arguments is now done for function calls. Not sure of the
306 impact this has on C++ member function yet.
308 Thu Jun 20 19:58:48 EDT 1991
310 valprint.c Rewrote the type printer. Broke it into two language
311 specific parts, adding the functions type_print_m2() and
313 An unfortunate consequence is this: if you debugging a C
314 program in Modula-2 mode (why?), info types does not work
315 well with regular expressions, since the types are printed
316 out in Modula-2 terminology, but stored in C terminology.
317 language.[ch] Added the functions new_type_last(), type_keyword(), and
318 type_sep() to aid in the printing of typedefs.
319 symtab.c Made the printing of typedefs as language independent as
320 possible through calls to new_type_last(), type_keyword(),
323 Fri Jun 21 11:50:26 EDT 1991
325 dbxread.c Check all incoming ennumerated types. If it looks like
326 Modula-2's BOOLEAN type, then change the type_code of the
327 type to TYPE_CODE_BOOL so we can process it as a boolean
329 valprint.c Replaced some of the 0x%x with calls to sprintf and
330 hexformat() in val_print().
331 language.[ch] Added the function hex_to_string(), which converts its
332 integral argument to a hexadecimal number (format is
333 language based) and returns the result as a string.
335 Mon Jun 24 12:25:07 EDT 1991
337 valprint.c Some functions call type_print_1() directly, instead of
338 value.h using type_print(), so they can specify where (column) to
339 print things. Since type_print() takes care of language
340 dependence, that needs to be called first. Added a
341 parameter depth to type_print() (so it is now like
342 type_print_1). Changed type_print to type_print_at, and
343 made type_print a macro that passes a depth argument of
345 symmisc.c Changed all calls to type_print_1 to calls to
347 Makefile.dist Made it possible to build GDB for a specific set of
348 depend languages. Do this by passing a definition for the macro
349 LANGS to make. LANGS should be a string containing a
350 space-separated list of language names (ie. LANGS="c m2").
351 The default is to build all languages. Note that grammar
352 files must follow the naming convention of <lang>-exp.y.
353 gdb.lang This holds the current value of the LANGS macro. It is
354 examined every time make is called, and is updated if
356 eval.c Added #ifdef _LANG_<lang> to these files.
357 expread.c Still need to add them to dbxread.c and coffread.c.
365 Mon Jun 24 16:33:11 EDT 1991
367 language.[ch] Added the functions hexformat_pre() and
368 hex_to_string_pre(), which take a prefix argument to
369 include in the format string. Thus, hexformat_pre("08") will
370 return "0x08x" (if the working language is language_c).
371 Made hexformat() and hex_to_string() calls to the above
372 with "" as the prefix argument.
374 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
375 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
376 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
377 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
378 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
379 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
380 valprint.c, vax-pinsn.c
382 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
383 calls to hexformat() and hex_to_string(). Format strings without
384 the leading "0x" were ignored.
386 depend Updated to take the above into account.
389 Tue Jun 25 15:27:18 EDT 1991
391 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
392 and type_check_t to keep track of the current state of
393 range and type checking.
394 main.c Added the variables range_mode, range_check, type_mode,
395 and type_check to record the current state of range and
396 type checking. Added initialization code to main().
397 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
401 Tue Jun 25 17:57:08 EDT 1991
403 dbxread.c process_one_symbol() updates the variable (enum language)
404 source_lang based on the extension of the filename
405 contained in the N_SO sybmol that started this symtab.
406 When end_symtab() is called, the value of source_lang is
407 put into the language field.
408 stack.c select_frame() sets working_lang (and possibly type_check
409 and range_check) to the language field of the symtab
410 associated with the frame that is selected if working_mode
411 is language_auto. If working_mode is language_manual, a
412 warning is printed and working_lang is not set.
413 language.c Added the function set_type_range(), which sets the value of
414 type_check and range_check (if their modes call for
415 automatic setting) based on the current value of
416 working_lang. A non-zero argument will cause the current
417 settings to be output.
420 Wed Jun 26 14:51:40 EDT 1991
422 eval.c Added range checks on assignment.
423 m2-exp.y Added the grammar for sets to the language. Currently,
424 these do not do anything except print an error message.
426 Wed Jun 26 17:01:04 EDT 1991
428 m2-exp.y Added the ability for parse_number() to parse negative
429 numbers. A global flag is set upon encountering a unary
430 minus. This was done to make, for example, 1 parse as a
431 CARDINAL, and not as an integer, per Wirth's examples in
432 Programming in Modula-2 ed.4.
433 valprint.c Added support for "set radix 2" by then setting
434 output_format to 't'.
435 eval.c Implemented range checking on subrange types. Added calls
436 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
437 Implemented MIN and MAX for ennumerated types. The
438 minimum value of an ennumerated type is defined by Wirth
439 as the first identifier, and the maximum as the last.
440 m2-exp.y Made octal numbers ending with "B" be characters and those
441 ending with "C" be numbers, per Wirth's book. (p. 34)
443 Thu Jun 27 14:11:52 EDT 1991
445 stack.c select_frame() now only sets working_lang, it does not
446 notify the user. If working_mode is language_manual, then
447 a warning is issued once.
448 main.c At the end of each call to execute_command(), working_lang
449 is checked against the local static (enum language)
450 current. If they differ and working_mode is
451 language_auto, the new settings of language, type and
452 range checking are printed out.
453 stack.c Modified frame_info() to include the language of the
454 current frame in the output of "info frame".
455 language.[ch] Added the function language_str() which returns the name
456 of the current language.
458 Fri Jun 28 15:33:14 EDT 1991
460 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
461 the language. INCL and DECL currently cause an error,
462 since sets are not implemented yet. INC and DEC are
463 implemented as PREINCREMENT/PREDECREMENT with one
464 argument, and as ASSIGN_MODIFY with two arguments.
465 eval.c Added type checking to the above cases.
466 value.h Added not_lval_constant to the lval_type ennumerated type.
467 not_lval_constant means that the value is a constant
468 value; that is 3 or 'a' or TRUE, not as in a constant
469 identifier. This is used to help coerce numbers such as 3
470 to either signed or unsigned numbers.
471 valops.c Added the function value_coerce_constants() which coerces
472 constant integers as following: if one is a constant and
473 the other is not, the constant's type is set to the type
474 of the other argument. If both are constants and one is
475 signed, the other is converted to a signed constant.
477 Sat Jun 29 17:26:29 EDT 1991
479 valarith.c Added a better range checker. It now checks range
480 (successfully) on integral operations [+-] (signed and
481 unsigned) for any C sized type. Still does not work well
483 int_in_size() returns an integer that is coerced to fit into
484 specified number of bytes.
486 Mon Jul 1 13:04:14 EDT 1991
488 language.[ch] Added the function binop_result_type(), which returns the
489 builtin (struct type *) type that would be the result of a
490 binop on the two values V1 and V2.
492 Wed Jul 3 19:22:53 EDT 1991
494 source.c Extended source_info() to include the source language in
495 the output from "info source".
497 Fri Jul 5 13:48:52 EDT 1991
499 utils.c Moved the support functions for the GDB set/show commands
500 dealing with language into language.c.
501 language.c Added the function language_info(), which displays info
502 about the current working language, type and range check
503 settings. Called via the GDB command "info language".
504 Added an initialization routine _initialize_language(),
505 that sets defaults for the language, type and range
506 variables and sets up the new GDB commands.
507 main.c Language setup moved to language.c.
510 Mon Jul 8 10:10:22 EDT 1991
512 valarith.c Debugged the range checker for arithmetic. Still does not
513 work for multiplication very well.
515 Mon Jul 8 12:40:37 EDT 1991
517 language.[ch] Added the function value_true() which returns non-zero if
518 its argument represents a boolean true value.
519 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
520 check the truth of an expression.
522 Thu Jul 11 12:51:34 EDT 1991
524 language.[ch] Added the predicate structured_type(), which returns
525 non-zero if the argument is a structured type.
526 Added the predicate pointer_type(), which returns non-zero
527 if the argument is a pointer type.
528 eval.c Added the ability to do addition and substraction on
529 pointers and integers. This case simply bypasses the
532 Thu Jul 11 14:41:42 EDT 1991
535 Added the symbol N_DEFD (0x4a) which is a definition
536 module dependency that is used by the GNU Modula-2
537 compiler and the linker. It is not important to GDB,
538 except that [dbx|coff|mips]read.c should ignore these
541 Fri Jul 12 16:07:00 EDT 1991
543 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
544 0 in val_print(). Also added statements to the else part
545 to coerce type (argument to val_print) to a pointer type
546 if it is an "array of unspecified length".
547 valops.c Added the function value_m2_string(), which returns a
548 (value) value which is a constant string, whose type is
549 (ARRAY [0..n] OF CHAR). The length field of the type
550 structure is set to zero, so it will be interpreted as an
551 "array of unspecified length".
552 stack.c Moved the language/frame mismatch check to
553 main.c:execute_command().
554 main.c The working language is recorded each time
555 execute_command() is executed. If working lang has
556 changed during its execution, then the new
557 language/type/range info is printed out for the user. If
558 the working language does not match the language of the
559 frame, a warning is issued.
561 Sat Jul 13 16:16:39 EDT 1991
563 eval.c Moved all the type-checking stuff for operators to
564 language.[ch] language.c. This is so we can keep language-specific
565 stuff (like for what type operators are defined) in
567 language.[ch] Added the function binop_type_check(), which checks to see
568 if its two (value) arguments are type-compatible with its
569 opcode argument. The opcode should represent an operation
570 involving an operator. Also added the macro function
571 unop_type_check, which calls binop_type_check with a
572 NULL second argument.
573 expprint.c Added Modula-2 operators to the op_print_tab, so info
574 expression.h break works correctly. Also added "op_string", which
575 returns the string corresponding to the (enum exp_opcode)
576 opcode that is its argument.
579 Sat Jul 13 18:26:18 EDT 1991
581 coffread.c Added code to record the type of function arguments with
582 each paricular function. Code is very similar to that
584 dbxread.c Moved add_param_to_type() to symtab.c
585 symtab.[ch] Added function add_param_to_type() from dbxread.c
587 *** NOTE: The above additions have not been tested.
589 Mon Jul 15 12:50:47 EDT 1991
591 langauge.[ch] Added the functions type_error and range_error, which work
592 like error() except if the type/range mode is set to
593 *_mode_warn, then they do not do a return_to_top_level(),
594 but merely print a warning.
595 Also changed [set|show]_[type|range]_command() to support
596 the new "warn" feature.
598 Thu Jul 18 17:50:54 EDT 1991
600 mipsread.c Added code to record the type of function arguments with
601 each particular function. Code is very similar to that
604 *** NOTE: The above additions have not been tested.
606 Fri Jul 19 11:19:10 EDT 1991
608 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
609 UMIN_OF_SIZE, which when given a size of a numeric type,
610 return the maximum and minimum value it can hold. UMAX...
611 and UMIN... return the result for unsigned types.
612 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
613 struct types. They call above macros.
614 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
615 avoid a name conlict with the above.
616 c-exp.y Added range checking on numeric constants in
617 parse_number() for completeness.
618 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
619 return 0 if working_lang is not language_c.
621 Thu Aug 8 14:17:22 EDT 1991
625 breakpoint.c Documentation strings of some commands changed to
626 eliminate the references to the C language where
629 Tue Aug 13 15:48:03 EDT 1991
631 m2-exp.y Added qualified identifiers to the grammar. The semantics
632 are slightly different from those of the GDB operator ::
634 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
635 type_exp, where type_exp is any valid type expression.
637 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
638 printcmd.c Modified ptype_command() so it actually parses the input
639 (necessary for type expressions with scope qualifiers).
640 Added the function ptype_eval() which expects an
641 expression composed of one OP_TYPE element.
642 *.[ch] Replaced all occurences of parse_c_expression with
644 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
646 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
648 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
650 Small fixes from Peter Schauer:
652 * infrun.c (child_attach): Lint.
653 * solib.c (find_solib): Handle shared libs version 2.
655 Small fixes from David Wood:
657 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
661 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
662 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
664 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
665 chars_per_line is at maximum (user typed `set width 0'). Fix
666 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
668 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
670 * coredep.c: include ptrace.h where necessary.
671 * mipsread.c(parse_lines): fix unsigned char problem that was
672 messing up line numbers on SGI's and possibly other MIPS based
674 * infrun.c (child_create_inferior): use better test to check
675 return val from setpgrp().
676 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
677 for sgi/irix support.
679 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
681 * mipsread.c (parse_symbol): Put non-static procedures
684 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
686 Patch together `text_start' and `text_end' for 29K port.
688 * exec.c (exec_command): If NEED_TEXT_START_END, define the
689 variables and set them based on the exec file.
690 * am29k-tdep.c: declare text_start.
691 * valops.c (call_function_by_hand): declare text_end.
693 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
694 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
695 because machines that do this will also have to know to
696 set NEED_TEXT_START_END. Besides, it was a redundant way to
698 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
699 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
702 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
704 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
706 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
707 Pass MUNCH_DEFINE to munch whenever we run it.
708 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
709 format string; use 0x%x instead.
710 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
711 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
712 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
713 * inflow.c: Handle `short' process group IDs.
714 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
715 and check for ptrace errors.
716 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
717 (coff_symfile_init): Initialize text_bfd_scnum.
718 (read_coff_symtab): Use it to find the text [and absolute?] sections.
719 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
720 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
721 Merge target arm case with other "easy" cases. Add target
722 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
723 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
725 * minimon.h, remote-adapt.c, remote-mm.c: Add.
726 * munch: Cope with RT/PC putting fns in data segment.
727 Restore ability to override `nm' by specifying MUNCH_NM.
728 * xconfig/rtbsd, xconfig/ultra3: New host systems.
729 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
730 and remote-adapt. Remove encapsulated coff #define's (the
731 support should go in BFD, and gdb shouldn't know or care).
732 * tconfig/a29k-kern: Same, but for remote kernel debugging.
733 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
734 * tm-29k.h: Update BADMAG (though it should go away).
735 Allow the register definitions to be overridden in another
736 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
737 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
738 DUMMY_SAVE_GR96, for handling kernel calling conventions
739 that use GR64+ rather than GR96+.
740 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
741 remote debugging of Ultra3 kernel. Includes tm-29k.h and
742 overrides various things.
744 * remote-mm.c (mm_attach, mm_wait): Handle attach like
745 child_attach does, making a clean stop in the newly attached
749 * coffread.c: Make coffread independent of any particular
750 variant of COFF. Avoid #include-ing any particular one except
751 internalcoff.h. BFD now passes key values for symbol reading
752 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
753 and the symbol masks and shifts); use them.
754 Remove obsolete end_of_text_addr.
756 * exec.c: Remove unused include files.
758 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
760 * Makefile.in (documentation targets): Pass $(M4).
761 Bugfix from eggert@twinsun.com (Paul Eggert).
763 * stack.c (down_silently_command): Check for stack existence.
765 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
767 * Makefile.in (VERSION): Update to 4.0.3.
769 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
771 * core.c (core_file_command): Print frame at coredump with
772 its level number, by calling print_stack_frame.
773 * frame.h: Add selected_frame_level, print_stack_frame.
774 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
775 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
776 Change print_sel_frame and print_selected_frame callers to
779 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
780 * symfile.c (free_named_symtabs): Ditto.
781 * main.c (main): wrap_here needs an arg.
782 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
783 (solib_add): Avoid noise.
784 (solib_create_inferior_hook): Lint.
785 (sharedlibrary_command): Move dont_repeat to here.
786 * utils.c (error): Call wrap_here to force buffered output.
788 Small patches from Peter Schauer:
790 * coffread.c (start_symtab): Free any existing line_vector before
792 (read_coff_symtab): Ditto for type_vector.
794 * source.c (lines_to_list): New variable, replacing function.
795 (all uses): Use as variable.
796 (_initialize_source): Add 'set listsize' and 'show listsize'.
797 * utils.c (lines_to_list): Remove function.
798 * stack.c (print_frame_info): Use as variable.
799 * defs.h (lines_to_list): Remove declaration.
801 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
803 * breakpoint.c (insert_breakpoints): Restore warning about
804 the program might be running in another process, but only for
805 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
806 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
808 * utils.c (error): if error_pre_print is set, print the string
810 * main.c (main, print_gnu_advertisement, print_gdb_version):
811 Reformat legalese so it always prints, but acts as an "I'm here"
812 message while symbols are being read. If any errors occur,
813 print a few newlines to set off the message and start it at the
814 left margin. Remove mention of "help" command, and don't yak
815 about symbol reading.
816 (catch_errors): Error string is now printed first in case of
818 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
819 suggest the "help" command.
821 * Makefile.in (VERSION): Set to 4.0.2.
823 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
825 * .gdbinit: Remove useless "rr" command. Set complaints
826 to 1 for people debugging gdb.
828 * breakpoint.c, remote-vx.c: Reword strings printed by
829 catch_errors callers.
831 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
833 * WHATS.NEW: "history write -> history save". Doc "write on/off".
834 (Fix from kenc@viewlogic.com.)
836 Fix some infrastructure to be able to cope with host and target
837 machines with different sized basic types (ints, ptrs, etc).
838 (Idea from pierre@la.tce.com (Pierre Willard).)
840 * values.c (value_from_longest): Rename from value_from_long.
841 Handle pointer types as well as integers, so that targets with
842 different pointer sizes from the host can be accomodated.
843 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
844 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
845 uses of value_from_long to value_from_longest.
846 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
847 the correct pointer type to value_from_long{est}.
849 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
851 * remote-vx.c: Remove obsolete code for calling functions via
852 vxworks kludge interface (it referenced value_from_long).
854 * valops.c (value_string): Find malloc with lookup_misc_func, not
857 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
859 Make writing to files work properly. (Fixes to BFD are also needed.)
861 * core.c (core_open): Open file ourselves, read or r/w, depending on
862 write_files. Use bfd_fdopenr.
863 * gdbcore.h (write_files): New variable.
864 * exec.c (write_files): Define variable, add set&show for it.
865 (exec_file_command): Use write_files to open for read or r/write.
867 Make shared library reading happen automatically. These changes
868 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
870 * inferior.h (stop_soon_quietly): Add to exported variables.
871 * infrun.c (child_create_inferior): call solib hook, if defined.
872 (child_attach): call solib hook, if defined.
873 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
874 (find_solib): Use lookup_misc_func rather than hand-rolled.
875 (symbol_add_stub): New stub for catch_errors.
876 (solib_add): Avoid output if !from_tty. Catch errors rather
877 than just calling symbol_file_add and bombing.
878 (solib_create_inferior_hook): Interface with the target process
879 to let it read and alloc shared libs, then figure out what it did.
881 * core.c (validate_files): Fix typo, soften warning.
882 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
884 * utils.c (fputs_demangled): Avoid duplicate printing if
885 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
887 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
888 (Fix from pierre@la.tce.com (Pierre Willard).)
890 * main.c (catch_errors): Change argument to a char * from an int,
891 since a char * can point to a struct full of glop, but an int
892 is not guaranteed to be able to hold a pointer.
893 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
894 breakpoint_re_set_one, breakpoint_re_set): Adapt.
895 * core.c (core_open, solib_add_stub): Adapt.
896 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
898 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
900 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
901 by adding .NOEXPORT target.
903 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
907 * Makefile.in (VERSION): Roll to 4.0.
908 (gdb.tar.Z): Make refcard.ps as well, for shipment.
910 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
912 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
915 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
918 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
920 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
921 reflect above name change
923 * WHATS.NEW: correct pointer to refcard.
925 * doc/gdb.texinfo: update New Features, Installing
927 * doc/gdbint.texinfo: add short description of configure +template
929 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
931 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
933 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
935 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
936 tar file, add dependencies for referenced doc files.
938 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
940 * coffread.c, symfile.c, stack.c: saberized.
942 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
944 * doc/refcard.tex: permuted Essential Commands sec
946 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
948 set/show symbol-reloading
949 default set complaints 0
951 RET-repeat disabled after prompted long displays
952 processID (attach) interpretation of 2nd GDB cmdline arg
954 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
956 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
957 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
958 breakpoint.c, main.c: lint.
960 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
962 Install new configuration scheme for GDB and friends.
964 * config.sub: Translate ordinary names to three-part names.
965 * configure: Use three-part names internally.
966 * configure.in: Translate three-part names to filenames.
968 * README, WHATS.NEW: Update for gdb-4.0.
969 * Makefile.in: Roll VERSION to 3.99.
971 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
973 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
974 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
975 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
976 to single structures rather than arrays; when passing
977 their address, use &. This avoids trouble with bdead compilers.
978 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
979 instead. This avoids portability headaches.
980 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
982 * source.c (open_source_file): Avoid ANSI const bdeath by
983 skipping declaration and then casting result value.
984 * tm-hp300bsd.h: Clarify comment.
985 * utils.c (strstr): Result is const char *; ANSI bdeath.
986 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
987 since system include file defines it differently from "defs.h",
988 though the two are equivalent for our purposes.
989 * tconfig/hp300bsd: Add m68k-tdep.o.
991 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
993 * tconfig/sun*4: Remove warnings about system assembler.
995 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
997 * mcheck.c: Avoid warning about undeclared abort fn.
998 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
999 it causes recursive calls to error() when used in cleanups.
1000 To do so requires that we make it a function, so we do.
1001 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
1002 * utils.c (do_cleanups): Remove the current cleanup from the
1003 chain *before* calling it, in case error() is called from it.
1004 The result won't be pretty, but won't be an infinite loop either.
1006 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
1008 * dbxread.c (read_struct_type): Grok anon structs for C++.
1009 (vb_name, vptr_name): Null terminate these strings.
1011 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1013 Minor bug fixes from BSD Net2 gdb:
1015 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
1016 returns 0, there is no previous frame.
1017 * breakpoint.c (commands_command): If !from_tty, don't call
1018 input_from_terminal_p().
1019 * dbxread.c (record_misc_function): Speed up slightly.
1020 (compare_psymbols): Ditto.
1021 * infcmd.c (do_registers_info): Take a second argument to
1022 determine whether to print float registers. "info registers"
1023 does not do so anymore. "info all-registers" does, now.
1024 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
1026 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
1027 * inflow.c (initialize_inflow): Set tflags_ours correctly.
1031 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
1032 executing_breakpoint_commands if we are interrupted by error.
1033 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
1034 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
1035 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
1036 catch_errors() so we can setup the frame regardless of whether
1037 the shared libs work.
1038 * ieee-float.c (double_to_ieee_extended): Get exponent from
1039 right place in little-endian systems. From John Carey.
1041 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1043 * main.c: Remove unused terminating_signals and catch_termination().
1044 (long_options): Terminate with a zero element.
1045 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
1046 (gdb_readline): Make call-compatible with readline.
1047 (init_signals): Improve comments re vfork vs. signal.
1049 * utils.c (prompt_for_continue): Use new gdb_readline().
1050 If we prompt for continuation, we don't let CR repeat the previous
1051 command, once we get back to a prompt. It's too easy to keep
1052 hitting CR, expecting "--more--" prompts, and have some long
1053 command start repeating on you.
1055 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1057 * blockframe.c (frameless_look_for_prologue): Speed up by
1058 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
1059 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
1060 Define two variants, one faster.
1061 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
1062 and return zero, rather than giving an error.
1063 (setup_arbitrary_frame): Initialize the PC in the new frame.
1064 (skip_prologue): Add a second arg saying whether we're just
1065 checking for a frameless function or not.
1067 * core.c (core_open, core_close, core_xfer_memory): Move
1068 section table pointers and bfd* into the target_ops.
1069 (core_open): Allow errors in shared lib reading, etc.
1070 (core_files_info): Describe shared library sections.
1072 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
1073 exec_files_info, set_section_command): Move section table
1074 pointers and bfd* into the target_ops.
1075 (add_to_section_table): Add BFD to section table.
1077 * target.c (target_xfer_memory, target_info): Pass target to
1078 xfer_memory and target_info functions.
1081 * gdbcore.h: Move struct section_table.
1082 * target.h: New home of struct section_table.
1084 * solib.c (solib_add): New argument is the target_ops whose
1085 section list is to be added to, if any. Reallocate the
1086 sections in that target to add any that come from shared libs.
1087 (throughout) so_sections renamed to sections.
1088 (solib_xfer_memory): Deleted.
1089 * tm-sunos.h (SOLIB_ADD): Add target argument.
1090 (SOLIB_XFER_MEMORY): Delete.
1092 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1093 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
1094 from target_ops. It's the same on all targets. Add two section
1095 pointers to target_ops.
1097 * stack.c (find_relative_frame): Dump ancient algorithm for
1098 "down", just use handy "next" pointers.
1099 (frame_command): Don't error if there is no stack; let user
1102 * inflow.c (new_tty_prefork, new_tty): New prefork routine
1103 modifies static state in the parent process; new_tty itself
1104 runs in the child and modifies the child's file descriptors
1105 to match the saved static state.
1106 * infrun.c (child_create_inferior): Call new_tty_prefork,
1109 * infptrace.c (child_xfer_memory): Add ignored target arg.
1110 * remote-eb.c (eb_xfer_inferior_memory): ''
1111 * remote-nindy.c (nindy_xfer_inferior_memory): ''
1112 * remote-vx.c (vx_xfer_memory): ''
1113 * remote.c (remote_xfer_memory): ''. Rename from
1114 remote_xfer_inferior_memory.
1116 * main.c (main): Only try to attach "corefile" argument if
1117 it starts with a digit.
1119 * symfile.c (symbol_reloading): New "set/show" variable.
1120 (symbol_file_add): Shorten message about symbol reading.
1121 (add_symbol_file_command): Merge with add_syms_addr_command,
1122 since this should work on all targets now.
1123 (stop_whining): Default to zero, to shut up complaints
1124 about bad symbol tables on many systems.
1125 (free_named_symtabs): Just exit unless symbol_reloading.
1127 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
1128 and add comment explaining shared library screw.
1130 * source.c: #if defined => #ifdef.
1132 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1134 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
1136 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1138 * doc/rdl-apps.texinfo: provide default readline-appendix finder
1139 (doc/Makefile knows how to make one for local config)
1141 * Makefile.in: use doc/Makefile for doc targets
1143 * doc/Makefile: GDB documentation now has its own Makefile
1144 doc/refcard.tex: renamed from "gdbrc.tex"
1145 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
1146 doc/gdbint.texinfo: add markup in "Cleanups" chapter
1149 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1151 * values.c (baseclass_addr): When reading target memory, use the
1152 length of the basetype, not the upper type. We've only malloc'd
1153 enough space for the basetype, leading to errors in free().
1155 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
1156 ends up as a function specially, since we know the actual type of
1157 the pointed-to address. This (somewhat) fixes display of
1158 expressions that include misc_function_vector names. Try `cond 1
1159 !strcmp("a","b")' then `i b'.
1161 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
1162 The child can be proceeded from inside wait_for_inferior in
1163 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
1164 getting skipped in that case.
1166 * expprint.c (print_subexp): Use filtered output, since the
1167 subroutines we call use it, otherwise the output is horribly
1168 mangled, since output of wrappable stuff comes out late.
1170 * Makefile.in: Bump VERSION to 3.98.1
1172 * infrun.c (child_create_process): Use execlp to find the
1173 shell to exec our target program. This requires some fiddling
1174 with `environ' since there is no execlpe().
1176 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1178 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
1179 Minor rearrangement of refcard permits two new make targets--
1180 gdbrc.dvi DVI output for refcard, using CM fonts
1181 gdbrc.ps PostScript refcard, using PS fonts
1183 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1187 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
1188 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
1190 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1192 * doc/gdb.texinfo: last changes for release.
1193 Minor typo and formatting fixes; incorporated most fixes remaining from
1194 filed mail commenting on earlier drafts.
1196 Added warnings: pipes don't work in run command;
1197 conditions are converse of assertions;
1198 step over fn without debug info goes to next fn;
1199 vars may have "wrong" values near fn entrance, exit
1201 Added example from Kingston on printing repeated nonadjacent values
1203 Added explicit mention that in Emacs gdb mode C-c and C-z are like
1204 shell mode for signals
1206 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
1207 doesn't sound so much like its parent "Stopping and Continuing"; also
1208 moved entries on continue to top of section, so they don't get lost.
1210 Improved installation directions in appendix, added manual formatting
1213 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1215 * configure.in: Remove xm.h and tm.h even if we aren't linking
1216 new ones, so "./configure sun4; ./configure none" does the right
1217 thing. Assume that alldeps.mak and depend are already built in
1218 srcdir, and avoid running "make" (particularly "make depend",
1219 which involves "gcc") from inside configure. Build Makefile
1220 directly rather than building Makefile.conf first.
1221 * configure: Regenerate with above changes.
1222 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
1223 to 3.98. Revise gdb.tar.Z procedure to produce a file
1224 called gdb-$(VERSION).tar.Z but which unpacks into a
1225 directory called "gdb". Move non-source files out of
1226 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
1227 (depend): Don't try to do "gcc expread.y".
1228 (expread.o): Update dependencies by hand.
1230 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1233 Fixed a variety of small typos that prevented info from formatting
1234 cleanly; altered too-long heading for GPL Appendix, as discussed
1235 w/RMS; Changed date on cover to July 91.
1237 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1240 (1) Applied some fixes due to comments from Larry Breed (easier ones
1241 through chapsec 5.2)
1242 (2) Eliminated use of @footnote---had my doubts about it anyways, and
1243 it's broken in latest texinfo
1244 (3) Introduced *some* use of [] for optional arguments, where
1245 explanation is not simpler by listing cmd w arg and cmd w/out arg
1246 separately. Still not using @deffn.
1247 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
1248 couple of headings are too long. Need patches to texinfo or revision
1251 * Partial update to README (which still needs work for this
1252 release!): (1) use of configure corrected for new script,
1253 (2) "make gdb.dvi" and "make gdb.info" mentioned.
1255 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
1257 * symtab.c (lookup_symbol): Don't complain right off about
1258 no debug symbols; use the misc function vector first.
1259 (list_symbols): Use misc function vector to find symbols
1260 that don't have debug info, and print them.
1261 (find_pc_symtab): Temporarily avoid fatal() when psymtab
1262 PC range doesn't match symtab PC range, as it does on the
1263 MIPS because our symtab reading isn't perfect.
1265 * dbxread.c (dbx_symfile_read): Make warning about
1266 "no debug symbols" slightly nicer.
1268 * source.c (select_source_symtab): If "main" symbol exists,
1269 but decode_line_spec can't find line info, don't just return
1270 a zero; try other source symtabs or give an error.
1272 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
1273 their low addresses first, then rip through fixing high addrs.
1275 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
1276 <runene@ifi.uio.no>.
1277 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
1279 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1281 * Minor, mostly mechanical, cleanup of doc subdir for clean
1282 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
1283 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
1285 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
1287 Mostly MIPS and general symbol-reading fixups.
1289 * doc/gdbint.texinfo: Add documentation on symbol-reading
1292 * mipsread.c: Remove kludges around #include "ecoff.h".
1293 Remove redefinitions of a_magic, etc, no longer used.
1294 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
1295 Fix global overview comments to match symfile.c protocol.
1296 (mipscoff_new_init): Eliminate cur_hdr if we have one.
1297 (mipscoff_symfile_read): Eliminate unused code. Avoid
1298 sorting all the symtabs, when all we have read here is psymtabs.
1299 The symtabs are sorted as they are created anyway. Tell
1300 condense_misc_bunches whether we're mainline.
1301 (psymtab_to_symtab_1): Pass filename when recursing, to make
1302 stack trace more informative.
1303 (parse_partial_symbols): Assume cur_hdr as argument.
1304 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
1305 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
1306 the TYPE_NAME of char *, since that's done in symfile.c.
1307 (free_numargs, parse_symbol, add_symbol, add_block,
1308 shrink_linetable): Declare these fns void.
1309 (upgrade_type): Convert tree of if's to switch. Clean up
1310 bogus "off == 0" handling with a complaint. Avoid setting
1311 field bitpos and bitsize of array with lower and upper bounds.
1312 Check specified bitsize of elements against their actual type's
1313 bitsize, and complain if different. Complain about unknown
1315 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
1316 (psymtab_to_symtab_1): Print names of subsidiary files that
1317 are being read in. FIXME, we read far too many files. This code
1318 is not the problem, the problem is in parse_fdr where the psymtabs
1320 (cross_ref): Result should indicate that we used one aux entry
1321 normally, or two if we encountered a "next" entry. This used
1322 to leave the caller pointing at the wrong aux entry.
1323 (add_symbol): If overflowed cur_block, reallocate it larger,
1324 chase all pointers to it, and complain(), rather than clobber memory.
1325 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
1326 (new_field): Only allocate one field initially, not two.
1327 Pull ++ out of macro argument. Simplify.
1328 (_initialize_mipsread): Avoid initialization of importd
1329 global_psymbols and static_psymbols.
1331 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
1332 to properly set pst->symtab; avoid searching for it.
1333 (symfile_fns): Improve comments, add a FIXME.
1334 * dbxread.c: Update comments to reflect symfile protocol.
1335 (read_ofile_symtab, end_symtab): Return the symtab.
1336 (psymtab_to_symtab_1): Set pst->symtab.
1338 * coffread.c (coff_symfile_read): tell condense_misc_bunches
1339 whether we're mainline.
1341 * symfile.h (sym_fns): Remove unused sym_discard member.
1342 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
1344 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
1345 the environment variable is not.
1346 * infcmd.c (finish_command): Use filtered printfs.
1347 * cplus-dem.c: Add struct tags to a few unnamed structs.
1348 * valops.c (value_coerce_array): Improve comments.
1349 * valprint.c (type_print_varspec_suffix): Print array size only
1350 if greater than zero.
1351 * m88k-tdep.c: Shift some lines left by one space, that had
1352 apparently been trashed at some point.
1353 * TODO: More things to do, a few got done.
1355 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1357 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
1358 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
1360 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
1361 * expread.y, findvar.c, symmisc.c: Ditto.
1362 * printcmd.c (address_info): Update printed forms of LOC_
1363 symbols. Elim LOC_EXTERNAL.
1364 (print_frame_args): Keep track of param stack offsets before
1365 re-looking up to find the local register param is kept in.
1367 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
1368 Further integration of mipsread into gdb. Eliminate unused
1369 routines, duplicate declarations. Handle static symbols in
1370 psymtabs as well as external symbols. When reading symtabs,
1371 insert symbols into the correct block (global, static, or a local
1373 (read_mips_symtab, parse_partial_symbols): Don't pass useless
1375 (mipscoff_symfile_read): Don't call select_source_symtab.
1376 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
1377 rather than SYMBOL_VALUE.
1378 (parse_external): Comment clobbering of top_stack.
1379 (parse_partial_symbols): Update comments. Allocate and parse
1380 static symbols as well as external symbols. FIXME, enum values
1381 are not handled in this pass, but should be. Inline new_psymbol.
1382 Use SYMBOL_VALUE_ADDRESS.
1383 (psymtab_to_symtab_1): Read symbols into global static block
1384 by default (until enter some function's local block context).
1385 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
1386 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
1388 * source.c (select_source_symtab): Select a source symtab
1389 from either the symtabs or, failing that, the psymtabs.
1390 (list_command): Update error message.
1391 (forward_search_command, reverse_search_command): Use getc, not
1392 fgetc, for speed. FIXME, add comment about buffers that die if
1393 overrun by long line.
1395 * values.c (unpack_field_as_long, modify_field): Avoid shifting
1396 by an entire word, which is not portable, if we have a 32-bit
1397 field. (Code in dbxread.c already turns such bitfields, if
1398 aligned, into ordinary ints, but fixing this will help for other
1399 symbol formats and for future changes.)
1400 * core.c (core_open): Handle ANSI const brain death.
1401 * utils.c (vprintf): Fix varargs typo.
1403 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1405 * findvar.c (find_var_value): Handle &function better.
1406 * TODO: Document work needed on &fn and &array.
1407 * printcmd.c (print_address_symbolic): New arg is the prefix
1408 to print if a name is printed.
1409 (print_address_demangle): Honor "set print address" now.
1410 Use new arg above to improve spacing of output.
1411 * valprint.c (val_print): When printing function pointers,
1412 print symbolic form too.
1413 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
1415 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1417 * core.c (memory_error): Reword error msg to mislead less.
1419 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
1421 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
1422 parse_partial_symbols): Use newer BFD internals (external_filehdr
1423 and external_aouthdr), byte-swap the fields that we care about
1424 before using them, and make the file header data local to
1425 read_the_mips_symtab rather than global.
1427 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
1429 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
1430 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
1432 * main.c (command_line_input): Flush stdout and stderr
1433 before every call to readline. This reportedly fixes a bug
1434 that comes up in Sys V running emacs-gdb and/or xxgdb,
1435 when stdin/out are pipes or sockets.
1437 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1439 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
1440 Avoid declaring Makefile dependencies, because GNU Make stupidly
1441 tries to update it if we do.
1443 * coffread.c: Revise for minor changes to bfd internal coff
1446 * configure: If -template= is given a relative path, make it
1447 absolute before recurring in subdirectories.
1449 * configure, configure.in, Makefile.in: Install "configure" script
1450 as replacement for config.gdb.
1451 * config.gdb, Makefile.dist, Makefile.sdir: Remove
1452 * README: Update for configure, mostly. FIXME.
1454 * Add dec3100 as equivalent to littlemips. Indicate in all host &
1455 target config files that they are for the host. When the lines
1456 get copied into the Makefile, this makes it more obvious what's
1459 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1461 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
1462 tabs, which end up in the disassembler output inadvertently.
1464 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1466 Make it compile cleanly in an ANSI GCC2 environment.
1468 * blockframe.c: <stdio.h>
1469 * cplus-dem.c: free takes a void *, ifdef __STDC__
1470 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
1472 * defs.h (alloca): Avoid doing anything if alloca already def'd.
1473 * stddef.h, stdlib.h: Remove these files.
1474 * symtab.c: Avoid declaring qsort, close.
1475 * symfile.c: Avoid declaring close.
1476 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
1477 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
1479 Assorted other changes.
1480 * dbxread.c: include "libaout.h", not "liba.out.h".
1481 * printcmd.c (print_frame_args): Set recurse properly for
1482 indentation of struct and array parameters.
1483 * valops.c (value_cast): Allow cast to void.
1484 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
1485 single_step() in a target-independent fashion.
1486 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
1487 set up to be ready to continue. This makes us target independent.
1488 * infptrace.c (child_resume): Remove call to single_step; now
1489 can single step a SPARC target of any kind.
1491 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1493 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
1494 docn into separate sections---basically chapters, plus two loose
1495 pieces that can be configured to go in different places. This
1496 allows GNU m4 to preprocess the manual without coredumping.
1498 * Makefile.dist: tell TeX where to find texinfo.
1500 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1502 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
1503 the new target "rdl-apps.texinfo" which captures the Makefile
1504 variable that records where to find the Readline libraries.
1506 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
1508 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
1509 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
1510 * defs.h (const, volatile): Only define if not already defined.
1511 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
1513 * README: Update for release 3.95.
1514 * config.gdb: Don't create readline dir in subdir builds.
1515 * main.c: Include with "..." form for non-system include files,
1516 so "gcc -MM" for "make depend" works.
1517 Include readline files with "...h" rather than <readline/...h>.
1518 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
1520 * coffread.c: Undo minor damage done by Rich Pixley. Use
1521 different internal and external representations of COFF
1522 data structures. Use new BFD routines for swapping them in and
1524 * symfile.c (free_named_symtabs): Avoid freeing file names that
1525 are null or empty. Old i960 tools seem to produce files that
1526 claim to have empty names, causing each successive file read
1527 to blow away the previous one.
1528 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
1529 Move deferred_stores to top of file, but don't separate its
1530 #define's from its variable. Add commentary.
1531 * Makefile.dist: Fix Rich damage; undo "configure" changes in
1532 favor of keeping the (working) config.gdb. Move readline
1535 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
1537 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
1539 * infptrace.c (fetch_registers): no result, since now void.
1540 * tconfig/news: target depends on m68k-tdep too.
1542 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1544 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
1547 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
1548 applied various small fixes due to or inspired by RMS comments
1550 * doc/gdb.texinfo: finished using all RMS comments, save those for
1551 appendices on readline and cmd history (which are in other source
1554 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1556 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
1557 chapter 9; (2) documented 'break' command's menu mode for
1558 overloaded names, in response to hgs problem report C++ p-31
1560 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1562 * doc/gdb.texinfo: (1) better introductory example; (2) more
1563 consistent use of @code, @samp, @file, @kbd throughout; small
1564 cleanups to first three nodes; (3) new "Contributors" node;
1565 (4) Appendix, Renamed Commands; (5) divert specialized startup
1566 instructions to "Targets" chapter for generic manuals, while
1567 leaving them up front for manuals specific to specialized
1568 environments; (6) apply fixes from RMS comments through chapter 4.
1570 * pretex.m4: modify explanatory text slightly (and redefine
1571 "regexp") to keep GNU m4 from complaining. (It still crashes
1572 later, but one step at a time...)
1574 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
1576 * readline/readline.c (update_line): Avoid dereferencing a pointer
1577 before comparing it to its bounds. Saber caught this.
1578 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
1579 and only set PC if tgetstr returned non-null. Saber caught this.
1581 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1583 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
1584 stuff for config manual) here where it counts; updated
1585 to use new subdir structure (gdb/doc/).
1587 * Makefile: generated from above via
1591 * gdbint.texinfo: added instructions on generating gdb.info* files
1592 locally for release. These are ordinary info
1593 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
1594 Makefile)---but due to use of texinfo 2, can't count on makeinfo
1595 to generate these, so we distribute them already formatted.
1597 * gdb.texinfo: included full Info node and menu crud (as generated
1598 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
1600 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
1601 put in comments-for-future gdb.info target (one day makeinfo will
1604 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1606 * gdb.texinfo: Updated to include new or old undocumented
1607 commands, at least the following (perhaps some others I forgot to
1608 record): info f, info float, info path, info program, info s, info
1609 set, info source, info terminal, info types, info user, set/show
1611 Also covered all recent GDB command renames for v4.
1613 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1615 * mipsread.c: Rather than keeping count of how many symtabs
1616 and psymtabs we have, for sorting purposes, count them when
1617 we need to sort. This fixes bug in rereading of symbol tables.
1619 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1621 * infcmd.c: renamed "info path" to "show paths"

1636 symtab.h, target.c, target.h: Lint.
1637 * core.c: setup and select frame after reading shared libs,
1638 else reading shared libs will clobber them. Lint.
1639 * utils.c (error): Force out any buffered wrap text.
1641 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1643 * remote.c: Remove decls of memory_insert_breakpoint
1644 and memory_remove_breakpoint, no longer used. (Suggestion of
1647 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
1648 to make it easier to interface to "configure"'d libraries.
1650 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
1652 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
1653 aliases for set/show print.

2157 New function to give correct error message.
2159 Thu Apr 11 17:19:41 1991 Jim Kingdon (kingdon at cygint.cygnus.com)

2162 target.c: Add target_preopen and target_command.
2164 (add_target): Call add_cmd and mess with targetlist->doc.
2165 core.c, exec.c, remote-eb.c, remote-nindy.c, remote-vx.c,
2166 remote-vx.68.c, inftarg.c, remote.c: Add doc field to target struct.
2167 Call target_preopen from open routine.
2169 * main.c: Rename editing_info to show_commands.

2191 * symmisc.c (same): same.
2192 (free_symtab): Make non-static.
2193 * symtab.h (free_symtab): Declare as exported void fn now.
2194 * dbxread.c (end_symtab, end_psymtab): Change comments.
2195 (initialize_dbxread): Call dbx_new_init() in case the first
2196 command is add-symbols.
2197 * target.c (dummy_target): Permit add_syms_addr_command.
2199 Sat Apr 13 14:46:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2201 Permit symbols to be superseded when new symbol files have
2202 been read in, particularly for VxWorks.
2204 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
2205 to the main file, as well as to include files. Also, put global
2206 functions into the global psymtab, to make "i fun" work.
2207 (end_psymtab): Free named symtabs and psymtabs for a file, once a
2208 new psymtab for it has been read.
2209 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
2210 a file, once a new symtab has been read for it.
2211 * mipsread.c: FIXME. We need to do the same for MIPS, but it
2212 looks harder to determine the top-level block before it's been
2213 queued to the psymtab list.
2215 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
2216 If we have wiped out any old symbol tables, clean up at end of
2218 (symbol_file_command): Don't reference symfile_fns if it's zero.
2220 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
2221 defines for the blocks of a blockvector that contain global and
2222 file-static symbols and the first of the smaller scope contours.
2223 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
2224 decode_line_1, make_symbol_completion_list): Use the above.
2225 * coffread.c (end_symtab, patch_opaque_types): Ditto.
2226 * dbxread.c (end_symtab): Ditto.
2227 * expread.y (block): Ditto.
2228 * mipsread.c (throughout): Ditto.
2229 * symmisc.c (free_named_symtabs): Ditto.
2231 * symtab.c (list_symbols): Process the first symbol of the
2232 static psymbols list.
2233 (types_info): Restore this function from its untimely #if 0.
2234 It's not perfect, but it is better than nothing.
2235 (_initialize_symtab): Restore "info types".
2237 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2239 * m68k-stub.c: Remote stub for 680x0's, created from
2240 rem-m68k.shar (which is removed).
2241 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
2242 Remove RCS log stuff now that we use CVS and it blows our diffs.
2244 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2246 * symmisc.c (free_named_symtab): Make it work, in its current
2247 kludgy fashion. Change result to indicate if we blew away bkpts.
2248 * dbxread.c (end_symtab): Accumulate result from
2249 free_named_symtab and print warning if we blew user's state.
2250 * symfile.h: free_named_symtab now returns an int.
2252 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
2254 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
2255 is the first symbol read, even if not mainline.
2256 (dbx_psymtab_to_symtab): symfile might be zero, cope.
2257 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
2258 (set_section_command): New command ("section xxx yyy" -- should
2259 be renamed to "set section xxx yyy" FIXME) which sets the
2260 base address of a section of the exec file, overriding the
2261 virtual address that BFD reports.
2263 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2265 * exec.c: Add add_syms_addr_command to exec_ops, so you can
2266 load symbols at any address while examining an exec file.
2268 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
2270 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
2271 for printing the float info is host-dependent, not
2272 target-dependent. FIXME.
2273 * i386-pinsn.c: Move #includes to top, remove useless ones.
2274 * i386-tdep.c: Don't bother including <.../reg.h> since we
2275 don't use it (and it doesn't exist on host systems).
2277 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
2278 Convert negative numbers properly.
2279 (ieee_test): Make numbers really random; fix format arg.
2281 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
2282 * core.c (core_detach): Unpush core_ops, which might not be on
2283 top. We used to just pop the top, which broke things. Don't
2284 need dont_repeat() any more.
2285 (core_file_command): Psst! Don't repeat it.
2286 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
2287 * expprint.c (print_subexp): Avoid switch fallthru on
2288 BINOP_ASSIGN_MODIFY, so we can print += and such.
2289 * frame.h: Fix typo.
2290 * inflow.c (kill_command): After killing inferior, print our
2291 current frame in the core file, if we have one.
2292 (generic_mourn_inferior): When inferior dies, either select
2293 the current frame (in the new target, e.g. core file), or
2294 set both the current and selected frames to NULL.
2296 Changes from Peter Schauer.
2298 * infptrace.c: Avoid <sys/ptrace.h> on USG.
2300 * Make all file names fit in 14 characters (sigh and damn!):
2301 mv hp300hpux-xdep.c hp300ux-xdep.c
2302 mv symmetry-xdep.c symm-xdep.c
2303 mv symmetry-tdep.c symm-tdep.c
2304 mv convex-opcode.h convx-opcode.h
2305 mv tm-vxworks960.h tm-vx960.h
2306 mv tm-vxworks68.h tm-vx68.h
2307 mv Makefile.srcdir Makefile.sdir
2308 mv gdb-int.texinfo gdbint.texinfo
2309 mv remote-sa.m68k.shar rem-m68k.shar
2310 mv remote-multi.shar rem-multi.shar
2311 * Makefile.dist, README, config.gdb, convex-pinsn.c,
2312 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
2313 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
2316 * command.c (user_info_1, user_info): New command for listing
2317 the user-defined commands.
2319 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
2321 * dbxread.c (really_free_pendings): Clear file_symbols
2322 and global_symbols after freeing them; otherwise, running
2323 this function twice (if it appears twice on the cleanup
2324 chain), we try to free things twice.
2326 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
2327 based on text_addr (the address of text in core), not on addr (the
2328 offset between text in the .o file and in core). This change
2329 is from Peter Schauer.
2331 * main.c: Define ALL_CLEANUPS as a cast of zero.
2332 (return_to_top_level): Use it.
2333 (main): Do all cleanups after each command run as part
2334 of the gdb startup sequence. Also do all cleanups before
2335 entering the command loop, and every time we exit the command
2336 loop and reenter. Before, the cleanups from the startup sequence
2337 were being left undone until the first error!
2338 (command_loop): Rename do_nothing cleanup to command_loop_marker
2339 so we can see it easily when examining the cleanup chain.
2340 (init_signals): Add another do_nothing for signal handling.
2341 (quit_command): Only try to kill target if it has execution.
2342 Problems in the target stack got us into a state where
2343 inferior_pid was nonzero but none of the targets had execution.
2344 In this state you couldn't exit gdb.
2346 * dbxread.c: Two changes from Peter Schauer.
2347 (echo_command): Fflush output after an echo command.
2348 (show_history): Pass all args to cmd_show_list.
2350 * utils.c (init_malloc): Call mtrace to turn on tracing
2351 if the environment variable MALLOC_TRACE is set to a file name.
2352 * mtrace.c: Add source file which provides a log of every malloc,
2353 free, and realloc to a trace file.
2354 * mtrace.awk: Add source file which analyzes the trace file.
2355 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
2356 (VERSION): Roll to 3.94.3.
2358 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
2359 (check_duplicates): Don't bother with watchpoints.
2360 (set_raw_breakpoint): Comment about danger of this routine.
2361 (watch_command): Parse and eval all args before calling
2364 * solib.c (find_solib): Avoid error in referencing memory to
2365 see if any more shared libraries have been added. This is
2366 particularly useful if the target has terminated. Bug reported
2369 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
2370 in bringing up 3.94.2 on the Sun-3.
2372 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
2373 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
2374 expression (in scope) before reenabling watchpoint.
2375 * signame.c (init_sigs): Add missing declaration of i, fix
2376 sys_siglist declaration.
2377 * source.c (list_command): Fixed range computation to use
2379 * stack.c (backtrace_command): Do not allow command if target has
2380 no stack, print informative error message.
2381 * target.c (target_command): Do not write into command line
2382 because this fails if the target command is used in a user defined
2383 command. [This change was enhanced by gnu to support any-
2384 unique-prefix matching on target names.]
2385 * valops.c (value_struct_elt): Avoid infinite loop on an
2386 erroneous attempt to print the member of function (try p main.p).
2388 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
2390 * expread.y (name_no_typename): Avoid reduce/reduce errors
2391 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
2392 Since the GDB parser really doesn't use name_no_typename in a
2393 name-only context, the parser can't tell the diff between
2394 names and numbers here. Avoid allowing a name_no_typename
2395 to be a NAME_OR_*INT to resolve the conflict.
2397 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2399 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
2401 * valprint.c (val_print_fields): bitfield printing didn't handle
2402 byte order. Indirect through a few more fns to cope.
2404 * values.c (modify_field): also cope with byte order.
2406 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2408 Cleanup for release 3.94.2:
2410 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
2411 include files. Roll version to 3.94.2.
2413 * coffread.c (init_stringtab): Read length into unsigned char
2414 array before swapping; don't assume 32-bit longs.
2416 * target.c (target_info): Don't bother with get_sym_file, just use
2417 the symfile global variable.
2418 * symtab.h, symfile.c (get_sym_file): Delete it.
2420 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
2421 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
2422 (read_type): Replace one more error() with complain().
2424 * mipsread.c (parse_partial_symbols): Replace printf with complain.
2426 * i960-tdep.c: Fix copyright attribution.
2428 * config.gdb: Quote all backquotes in doublequotes. You can
2429 quote me on that. BSD 4.4 shell found this one.
2431 * infptrace.c (throughout): The third argument to ptrace is an
2434 * infrun.c (wait_for_inferior): When program has terminated, we
2435 have to call target_terminal_ours before we pop that target off
2436 the stack (e.g. before a call to target_kill or
2437 target_mourn_inferior). This fixes problem where a program
2438 terminates, then GDB stops for (tty output) and you have to type
2439 "fg" to the shell to resume it. FIXME: This code for what to
2440 do after termination really should be in normal_stop instead.
2442 * gdbcore.h (read_memory_check): Change declaration; it changed
2445 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
2446 4.4 prereleases, this avoids a bug in their sgtty compatability
2448 * remote.c: Use terminal.h rather than hand-rolling the same.
2450 * signame.c, signame.h (psignal): Arg is unsigned, not int.
2451 * utils.c (strsave, strstr): Fix arg types.
2452 * valprint.c (val_print): lint
2454 MIPS symbol table support from Per Bothner:
2456 * symfile.c (symtab_fns): Remove initializer table that needs to
2457 be hacked for each new symbol file format supported.
2458 (add_symtab_fns): New function, chains symbol table
2459 handlers into the global list.
2460 (symfile_init): Search this list.
2461 * symfile.h: Add next pointer, declare add_symtab_fns.
2462 * coffread.c (_initialize_coffread): Call add_symtab_fns.
2463 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
2465 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
2466 symbol *). Thus, we no longer need the hack to trash
2467 pst->filename. Good, since that hack confused code in symfile.c!
2469 (reorder_symtabs, destroy_all_symtabs): Removed static
2470 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
2471 Instead, the latter now uses a temporary array (stack-allocated
2472 from an obstack, and then freed).
2474 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
2475 haven't been set in the outermost stBlock of a procedure. This was
2476 a problem with f77 binaries on Ultrix 4.?.
2478 (new_symtab, new_symbol, new_type): Continue changing code to use
2479 obstacks more and otherwise conform to dbxread internal style.
2480 Made the free_code of symtabs be free_linetable (as in dbxread)
2481 instead of free_contents. This implies memory leaks when reading
2482 a new symbol table, until the conversion is finished. Did change
2483 (struct symbol) and (struct type) to be allocated on the
2484 symbol_obstack. Blocks and blockvectors are among the things
2487 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
2488 tested much, but it solved one problem (reported by Meissner), and
2489 cleans up some other things. The problem happened when an
2490 included file contains actual code (functions) and not just
2491 definitions. The mips coff is a little inconvenient there, since
2492 it may cause a procedure to be mapped to the wrong psymtab.
2494 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
2495 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
2496 this will need work for the new core paradigm.
2498 Opcode patches from the net:
2500 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
2501 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
2502 missing altogether - they are added here. From Bruce Bauman.
2503 * mips-opcode.h: The low mask for C0 instructions was too small.
2504 From Garrett Lau. I modified the fix to check the entire 32-bit
2507 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
2510 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2512 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
2514 * dbxread.c (read_type): Pointer subtraction (value_sub in
2515 valarith.c) sometimes failed because the types of the
2516 pointers being subtracted were not identical.
2517 These differed because dbxread.c was allocating pointer types
2518 using dbx_alloc_type+smash_to_pointer_type instead of
2519 lookup_pointer_type. I failed to find a justification for the
2520 former, so I changed it to use the latter. Similarly, I
2521 replaced smash_to_function_type by lookup_function_type,
2522 and smash_to_reference_type by lookup_reference_type.
2524 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
2525 _initialize_mipsread): corresponding changes.
2527 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
2529 * source.c (mod_path): Do tilde_expand on each component of the path,
2530 rather than on the (list of) paths as a whole.
2531 (print_source_lines): Set first_line_listed in addition to
2532 current_source_symtab and current_source_line. If the source was
2533 not findable, after a "dir" command to fix the problem,
2534 a "list" would get the wrong lines.
2536 While I was there... (gnu):
2538 * dbxread.c (read_type): Change error to complaint.
2540 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2542 First attempt at detailed understanding of symbol table memory alloc.
2544 * dbxread.c (dbx_symfile_read): Free our string table if we
2545 aren't the mainline. Free the "info" struct since we're done with
2547 (init_psymbol_list): Free any previously allocated psymbol lists.
2548 (): FIXME: Should realloc-down the psymbol lists when done reading
2549 the main symbol file?
2551 * symmisc.c (free_symtab): Free fullname field too.
2553 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
2554 (REGISTER_ADDR): Make result type unsigned int.
2556 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
2557 define REGEX must also define REGEX1 (its dependency).
2559 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
2561 * tconfig/i960: No longer works, points you at vxworks960 or
2564 * xgdb.c, XGDB-README: Remove file. Users can get the much
2566 * Makefile.dist: Remove all trace of xgdb.
2568 * breakpoint.c (breakpoint_1): Pass demangle arg to
2569 print_address_symbolic.
2570 (clear_breakpoints): Remove unused function.
2571 (breakpoint_re_set_one): Guts of breakpoint_re_set.
2572 (breakpoint_re_set): Use catch_errors to do them all anyway.
2574 * gdb-int.texinfo (Host versus Target): Add section on what is
2575 a "host" feature versus what is a "target" feature.
2577 * infcmd.c (path_command, path_info): Handle the PATH variable
2578 (object search path) as conveniently as the source search path.
2579 * environ.c (set_in_environ): Set some vars in GDB's environment,
2580 in addition to the child's. PATH, G960BASE, G960BIN for starters.
2581 * source.c (mod_path): New function, from guts of
2582 directory_command, modifies a path. Used by path_command.
2583 (directory_command): Call it.
2584 * defs.h (strsave): Declare.
2586 * utils.c (sevenbit_strings): Add new printing option.
2587 (printchar): Use it.
2588 (strsave): Provide this handy helper routine.
2589 (set_width_command): Rename set_screen_width_command.
2590 (_initialize_utils): "set screen-width" => "set width";
2591 "set screen-height" => "set height"; add sevenbit-strings.
2593 * infcmd.c (do_registers_info): Print floating point registers
2594 in raw hex as well as float format, regardless of whether it is
2595 a "virtual" convertible register.
2596 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
2597 regs as a double, just in case it's being used that way.
2598 * values.c (unpack_long): Comment on array/function coercion.
2599 (unpack_double): Argument is in target byte order now. For
2600 integer arguments, just call unpack_long and float the result.
2601 * m68k-tdep.c: include defs.h for "const" handling.
2602 * remote-nindy.c: Use ieee-float stuff.
2603 (nindy_fetch_registers): Unpack double regs to host double, then
2605 (nindy_store_registers): Pack extendeds to host double, flip
2606 around by misusing unpack_double, send as target double.
2608 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
2609 zero, as when stopped at the first instruction of a process.
2611 * blockframe.c: Fix filename in comment (param.h => tm.h).
2612 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
2613 * tm-68k.h: Fix typos.
2615 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
2617 Changes from a bringup on the DEC Vax under Ultrix 4.0.
2619 * coredep.c (fetch_core_registers): Pass end-address of register
2620 section to register_addr as expected. Don't call supply_register
2621 if we'd just pass it garbage.
2623 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
2625 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
2627 * target.c (push_target, target_info): Cast enums to int for < or
2630 * stack.c (print_frame_info): Identify source file & line
2631 even if we can't print it.
2633 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
2635 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
2637 Clean up IEEE floating point support.
2639 * ieee-float.h: New file.
2640 * ieee-float.c: Write real routines to convert between host
2641 doubles and various target IEEE extendeds.
2642 * m68k-xdep.c: Eliminate assembler code for extended floats.
2643 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
2644 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
2645 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
2646 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
2647 double_to_ieee_extended.
2648 * i960-tdep.c: Define ext_format_i960.
2649 * m68k-tdep.c: Define ext_format_68881.
2650 * sparc-tdep.c: Define ext_format_sparc, though unused.
2651 * Makefile.dist (HFILES): Add ieee-float.h.
2652 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
2655 Obsolete the "coffstrip" program in favor of using BFD's strip.
2657 * nindy-share/coffstrip.c: Remove file.
2658 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
2659 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
2660 * tconfig/nindy960: Remove reference to coffstrip.o.
2662 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
2664 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
2666 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
2667 * dbxread.c: Remove static symfile_bfd.
2668 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
2670 * inftarg.c (child_detach): Pop the child_ops vector if the
2671 detach is successful.
2672 * remote-nindy.c (nindy_create_inferior): Don't push a new
2673 nindy_ops since nindy uses the same one for execution and memory
2675 * core.c (core_ops): Use child_attach and child_create_inferior
2676 rather than default attach and create_inferior functions.
2678 Handle floating point registers in core files.
2680 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
2681 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
2682 This version untested since BFD doesn't yet support sun3 core
2684 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
2685 conventions. Fix comments and style. This version has not
2686 been compiled yet, since we have no HP inhouse.
2687 * core.c (get_core_registers): Look for two sections, ".reg"
2688 and ".reg2", and pass both to fetch_core_registers sequentially.
2690 Revise directory path yet again.
2692 * source.c (forget_cached_source_info): Not static any more.
2693 (init_source_path): New default source path is "$cdir:$cwd".
2694 (dir_command): Handle variable arguments ($cdir, $cwd).
2695 (source_info): Print "Compilation directory" rather than
2696 "Originally compiled in" to remind people of $cdir.
2697 (openp): If the path contains $cwd, use current directory.
2698 (open_source_file): If compilation directory is known, replace
2699 first $cdir in path with the compilation directory.
2700 (print_source_lines): Even if we can't print the lines, set the
2701 current symtab and line for future commands like "info source" or
2702 "breakpoint". Also, error message now contains the file name,
2703 line number, and file access error message.
2704 (_initialize_source): Fix help text to describe changes.
2705 * main.c (cd_command): Forget cached source info when we chdir.
2706 * utils.c (strstr): Add simple implementation.
2708 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
2710 * coffread.c (read_one_sym, init_linetable, init_stringtab):
2711 Byte-swap COFF symbol tables if necessary when reading them in.
2712 Use complain() to replace error message in one spot. Needs
2713 corresponding change in bfd/coff-code.h to make some symbol
2714 swapping routines non-static.
2716 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
2718 Merge changes from Eirik Fuller, for UTek.

2721 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
2722 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
2723 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
2724 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
2725 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
2726 declarations of errno.
2728 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
2730 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
2731 <rpc/rpc.h> and <rpc/types.h>.
2733 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
2735 * i960-tdep.c (examine_prologue): Add new argument limit,
2736 which stops the scan at the end of the prologue, or at the PC.
2737 This fixes a problem where it walks down into the code for the
2738 user's statements if that code looks like function prologues.
2739 Mark Fox and I have been bouncing this code back and forth, making
2740 small changes to it. Callers changed to match.
2742 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
2744 Cleanup for gdb-3.94 release final:
2746 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
2747 the .c files from vx-share and nindy-share, from the various
2748 macros, since they are not found via ALLDEPFILES.
2749 (SFILES): Add tm-i960.h.
2750 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
2751 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
2753 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
2754 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.

2758 * am29k-tdep.c: Add contribution line.
2759 (examine_prologue): Cache information about function prologues in
2760 the misc-function-vector to avoid lots of references over the
2761 serial line while examining instructions.
2763 * core.c (core_close): New function made from cleanup_core.
2765 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
2766 remote-vx.c, remote.c, target.c, target.h,
2767 Update target_ops vector to add attach, close, and load entries.
2768 Use add_syms_addr_command, not add_file_addr_command, for
2769 add_file. Break out close routine from existing code.
2771 * dbxread.c (really_free_pendings): Don't free pending_blocks;
2772 they are in an obstack.
2773 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
2775 (define_symbol): Add symbol type parameter; change callers;
2776 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
2777 it to influence the symbol class on the i960.
2778 (define_symbol): Swap LOC_CONST's into target byte order.
2780 * exec.c (exec_close): New function.
2781 (exec_file_command): Call it.
2783 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
2784 Fix byte order of frame pointer.
2785 (read_var_value): Result of 0 if var's value can't be found,
2786 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
2787 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
2788 (locate_var_value): Use read_var_value and use its lazy address
2789 as the location of the var's value. Lint.
2791 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
2794 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
2795 obsolete Intel versions in favor of vxgdb versions.
2796 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
2797 code dealing with byte order of values, which Intel did in host byte
2798 order rather than gdb-4's target byte order.
2799 (i960_frame_chain_valid): Move to nindy-tdep.c.
2800 (examine_prologue, skip_prologue, frame_find_saved_regs,
2801 frame_args_address, leafproc_return, saved_pc_after_call,
2802 pop_frame): Add vxgdb versions from Mark Fox.
2803 (examine_prologue, frame_struct_result_address): Add code
2804 to deal with the saved value of G13 (struct return address
2806 (frame_args_address): Modify Mark's version to prefer the
2807 saved value over the current value in the topmost frame.
2808 Cache result in the frame info to avoid performance hair in
2810 (print_fault): Add gdb960 code for printing faults.
2811 (_initialize_i960): Actually call check_host.
2813 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
2814 add stub routines. FIXME, these currently just return zero!
2816 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
2817 (attach_command): Call target_attach, not target_open, now.
2819 * infrun.c (normal_stop): Make global, not static, for vx_attach.
2820 (child_attach): Rename from child_open.
2821 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
2822 don't confuse it with a zero step_resume_break_address.
2824 * inftarg.c (child_detach): Eliminate inferior_pid test.
2825 (child_files_info): Clean up message a bit.
2826 (child_ops): Use child_attach, not child_open, to attach.
2828 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
2829 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
2830 findvar.c to here, since it depends on the contents of the
2831 shadow_contents of breakpoints, but keep if #if 0 since it is
2834 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
2837 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
2838 (ptype_command, display_command): Eliminate have_inferior_p and
2839 have_core_file_p in favor of target_has_stack or
2840 target_has_execution.
2841 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
2842 code for actually finding the values of arguments, though we still
2843 keep track of the maximum stack offset for use in printing unnamed
2844 arguments. Handle missing FRAME_ARGS_ADDRESS.
2846 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
2847 (struct nindy_regs): Define registers passed to/from nindy.
2848 (nindy_fetch_registers, nindy_store-registers): Translate between
2849 nindy and GDB formats for the registers.
2850 (dcache_init): Statically allocate the cache, since it was being
2851 allocated by a malloc that was never freed anyway.
2852 (nindy_create_inferior): Error, not core dump, if no exec file.
2853 (nindy_before_main_loop): Use target_load, not target_add_file.
2855 * remote-vx.c (net_load): Specify large timeout for load
2856 requests. Allow user to break out with INTERRUPT.
2857 (net_break): Remove useless code, clean up. Change callers.
2858 (parse-args, skip_white_space, find_white_space): Clean up arg
2859 parsing to cope with quoted strings.
2860 (net_wait, net_quit): Never call error, just return status.
2861 (vx_read_register, vx_write_register): Cleanup status checking.
2862 #ifdef the code based on which CPU we are using (960 or 68k),
2863 FIXME, this should be completely general but it isn't yet.
2864 (vx_xfer_memory, vx_resume): Cleanup status checking.
2865 (vx_run_files_info): Improve message.
2866 (vx_load_command): Renamed from vx_add_file_command. Allow load
2868 (net_ptrace): Remove unused routine.
2869 (vx_wait): Adopt code from vxgdb960 to cope with broken
2870 connections to target machine and prompt to disconnect. Remove
2871 debug printouts. Map some EVENT_'s to SIGnals.
2872 (add_symbol_stub, vx_open): Print names of object files we found,
2873 and "ok" if we read their symbols OK. Clarify output in general.
2874 (vx_attach, vx_detach, vx_kill): Add these commands.
2875 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
2876 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
2877 "info files" output, and create_inferior, since we already have
2880 * stack.c (frame_info): Replace Frame_unknown with 0.
2881 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
2882 (return_command): Pop until the PC matches as well as the FP,
2883 so it works even if the FP is shared with another function,
2884 as in "frameless" or "leaf" procedures.
2886 * symfile.c (load_command): renamed from add_file_target_command.
2887 (add_syms_addr_command): renamed from add_file_addr_command.
2888 (add_syms_command): Stub to call target_add_syms.
2889 (_initialize_symfile): Change command names and descriptions,
2890 add-file => add-syms, and load from alias to its own command.
2892 * target.c (kill_or_be_killed, maybe_kill_then_attach,
2893 maybe_kill_then_create_inferior): Default for attempts to start
2894 a process, if one is already running, is to ask about killing
2895 it and retry if yes.
2896 (upstack_create_inferior): #if-0 it, strata obsolete it.
2897 (push_target, unpush_target, pop_target): to_close() a target
2898 before unstacking it.
2899 (target_info): Renamed from target_files_info.
2900 (_initialize_targets): Rename "i files" as "i target", accessible
2903 * target.h: Improve comments about the target_ vectored routines.
2905 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
2906 Convert commenting style to standard GNU style.
2907 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
2908 (SKIP_PROLOGUE): No longer a no-op.
2909 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
2910 (*_REGNUM): Sort register numbers.
2911 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
2912 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
2913 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
2914 are now 10 byte extendeds, not 8 byte doubles.
2915 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
2916 for nindy versus vxworks targets. FIXME, this should possibly go
2917 in the target vector.
2918 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
2919 frame_saved_regs and arg pointer with each frame.
2920 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
2921 (FRAME_ARGS_ADDRESS): Use cached result.
2922 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
2923 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
2924 (PRINT_RAMDON_SIGNAL): Call print_fault.
2925 (POP_FRAME): Now works.
2927 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
2928 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
2929 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
2930 (ADDITIONAL_OPTION_HANDLER): use target_load, not
2933 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
2934 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
2936 * valarith.c (value_subscripted_rvalue): Avoid handling
2937 floats and doubles specially; it gave alignment errors. Lint.
2939 * valops.c (value_of_variable, value_of_this): Error if unknown
2942 * valprint.c (print_floating): Bcopy rather than pointer-deref,
2943 to avoid alignment problems.
2944 (value_print): Handle unknown value address.
2945 (cplus_val_print): Two args are ignored; remove them. Change caller.
2946 (val_print): Use unpack_long rather than pointer-deref.
2949 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
2950 to avoid alignment problems.
2951 (value_being_returned): Error if return value unknown.
2952 (set_return_value): Add bogosity warning, FIXME. *
2954 * TODO: A woman's work is never done.
2956 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
2957 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
2958 Add ieee-float.o to OBS.
2959 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
2960 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
2961 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
2963 Changes to generalize the VxWorks RPC protocol slightly, to handle
2964 i960 as well as 68000.
2966 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
2967 * vx-share/reg.h: Produce i960 regs #ifdef I80960
2968 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
2969 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
2970 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
2971 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
2972 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
2973 so they will move in target byte order rather than network
2974 byte order (happens to be the same).
2976 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
2978 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
2980 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
2983 Add contribution lines to various files, showing where they
2986 * breakpoint.c (break_insn, check_break_insn_size,
2987 read_memory_nobpt): Remove to mem-break.c.
2989 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
2992 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
2993 entry has bad register number. This change is not
2994 tested in this release, FIXME.
2996 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
2999 * value.h: Force value's contents field to be aligned to hold
3000 at least a double or a long long (if supported). This avoids
3001 doing bcopy's in and out of the contents field.
3003 (step_1): Avoid coredump under obscure circumstances when we
3006 * symtab.h (misc_info): Add field to misc function vector for
3007 any kind of cached information the target code desires. AMD
3008 29000 uses this to avoid repeating examine_function_prologue's.
3010 * coffread.c: Lint. Remove static symfile, read_section_header.
3011 core.c (have_core_file_p): Lint: remove.
3012 expprint.c (print_subexp): Lint.
3013 infptrace.c, valops.c, valprint.c: lint.
3015 Roll in changes from vxgdb-5.0.1:
3017 * symtab.h: Comment byte order of each address class. Add
3018 LOC_LOCAL_ARG for frame-relative args (960).
3019 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
3020 symtab.c, symmisc.c: ditto.
3022 * infrun.c (init_wait_for_inferior): Clear stop_signal.
3024 * remote.c (remote_resume): Error if resume with a signal.
3026 * symfile.c (prim_record_misc_function): Clear misc_info.
3027 (fill_in_vptr_fieldno): Check stub type of arg.
3029 * valops.c (value_cast): Avoid looking up names of types whose
3030 name we don't know, to prevent coredump. Sun CC produces typedef
3031 rtx and the name of *rtx is zero...
3033 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3035 Roll in changes from final AMD 29000 port (Tiemann).
3037 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
3038 for ../include/a.out.encap.h. This might not work now that BFD
3039 is separately compiled. Instead, BFD support for encap will have
3040 to translate machine type 29k into the right COFF_MAGIC.
3042 * infcmd.c: Remove references to inferior_pid that aren't used
3043 in actual ptrace calls; use target_has_execution, etc.
3044 (have_inferior_p): Remove function.
3045 (program_info): Print target info rather than "process number";
3046 avoid gratuitous messages unless from_tty.
3047 (run_stack_dummy, finish_command): Set proceed_to_finish.
3048 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
3049 main.c: Lint. Lose have_inferior_p().
3050 inferior.h (have_inferior_p): Remove, lint.
3051 (proceed_to_finish): Add flag to ask that all regs be saved
3052 by normal_stop, for the few commands that need it, speeding up
3053 serial I/O. Add comments to stop_registers.
3055 * remote-eb.c: Remove newline from breakpoint message we grep
3056 for. Never time out when running the user program.
3060 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3062 Roll in changes from vxgdb-5.0.1:
3064 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
3065 symbol in its raw form, we are processing an unlinked ".o" file.
3066 See if the target environment has assigned it an address, using
3067 target_lookup_symbol (VxWorks does), and enter it into the symtab
3070 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
3071 68k versions for a simpler version that assumes zero FP at bottom.
3072 Fixes bug of truncated stack reports.
3074 * target.h (target_lookup_symbol): Define this routine's args
3075 and result, finally.
3077 * target.c (nosymbol): Default routine for target_lookup_symbol.
3078 (target_default): Default lookup_symbol and call_function too.
3079 (files_info): Only print has_all_memory warning if a non-dummy
3082 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
3083 vx_convert_from_virtual): If target does not have floating point,
3084 zero register "values", and avoid doing cross-net conversions.
3085 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
3086 (vx_open): Rearrange code that attaches to target and reads
3087 symbols for all loaded modules, to work if some of the modules
3088 are not accessible. Add symbol_stub() and add_symbol_stub()
3089 as callbacks from catch_errors(). Allow connect attempt to be
3090 interrupted painlessly with ^C (FIXME, there are still some bugs
3091 if the interrupt happens during symbol reading.). Print
3092 final message with puts_filtered, since symbol messages are
3097 * main.c (catch_errors): Only print errstring if non-null.
3098 (command_loop): Avoid an ioctl per command to test ISATTY.
3100 * remote-vx.c (net_load): make static; avoid sophomoric msg.
3101 (vx_xfer_memory): Return correct result!
3102 (vx_files_info): Indicate whether target has float or not.
3103 (vx_lookup_symbol): Complain, not error, if target gone.
3104 (vx_open): Print "Connected" msg before disabling immediate-quit.
3105 [FIXME: lookup_symbol and vx_open changes need testing.]
3107 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
3108 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
3109 contributor lines and update copyrights to 1991.
3111 Changes from an attempted H-PUX host port:
3113 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
3114 defines PT_ATTACH and PT_DETACH but not PT_KILL.
3115 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
3116 * remote-vx.c: include <sys/time.h> for HPUX.
3117 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
3118 "core_file_command" routine to BFD regime. May not work yet.
3120 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
3122 * xgdb.c: Replace X10 version with some VJ version.
3123 (FIXME: Its copyright assignment is not on record.)
3124 * xgdb.c: Update include files to X11R4 (Xaw crud).
3125 (xgdb_display_source, create_text_widget): fix call to
3126 get_filename_and_charpos. Rewack source window stuff for X11R4
3127 (gleaned from include files, and "nm's" of binary libraries, since
3128 I had no doc available).
3129 (append_selection, append_selection_word): Disable with FIXME
3130 since R4 changed interface here.
3131 (create_buttons): Add back the old set of buttons.
3132 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
3134 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
3135 Roll VERSION to 3.94 (not yet final though).
3137 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3139 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
3140 obstack_int_grow, obstack_int_grow_fast): Eliminate
3141 cast on left of assignment, which gives MIPS cc fits and is
3144 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
3145 F_ALIAS. Use printf, not fprintf, when not passing a file
3147 (compare_opcodes): Check that identical instructions have
3148 identical opcodes, complain otherwise.
3150 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
3151 was reported by Roland McGrath.
3152 (unimp): Only match if exactly zero instruction. (Roland)
3153 (branches and traps): Generate all variations of these
3154 instructions with macros, based on a single call that defines
3155 each condition name and its binary representation.
3156 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
3158 * valprint.c (val_print_fields): Take, and use, format parameter.
3159 This means that "p/x struct" again prints the elements in the
3160 desired format. Changed callers.
3162 * stack.c (frame_info): Use filtered output, and indicate wrap
3163 points. Remove kludgy formatting designed to avoid line wrap.
3165 * utils.c (wrap_here): If the line is already full (because
3166 we had printed a long indent or long wrapped string), do an
3167 immediate newline-and-indent.
3169 * m68k-pinsn.c (print_insn_arg): Bugfix from
3170 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
3171 instruction is incorrectly disassembled as bkpt #8.
3173 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
3174 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
3175 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
3176 and then will dump core (sometimes). I traced it back to an
3177 uninitialized symfile_name in psymtab_to_symtab.
3178 (const_vol_complaint): Add quotes to message.
3179 (define_symbol): Only believe line number if gcc_compiled.
3180 Avoid allocating symbol if we will not return it.
3182 Add target strata support so that newly established targets go
3183 into their right place in the target stack (e.g. a new exec file
3184 doesn't wipe out the ability to access the running process).
3186 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
3187 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
3188 and initialize it properly in all the targets.
3190 * target.h: Document strata. Change return type of push_target.
3192 * target.c (nomemory): new function for dummy memory access.
3193 (tcomplain): Rename complain, now also used in symfile.c.
3194 (push_target): Push targets within strata. New return value shows
3195 whether new target is on top of stack or not. Always keep dummy
3197 (target_files_info): Ignore dummy target.
3199 * core.c (core_open): Warn user, and skip accessing file, if the
3200 core target is not the topmost target in the stack.
3201 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
3204 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
3205 target_ops, it doesn't belong there since we have no regs there.
3206 Change name of target from machine => memory to clarify.
3208 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
3210 * Freeze version 3.93 for release.
3212 * Makefile.dist: Handle vx-share and nindy-share subdirs
3213 properly when building gdb.tar.Z.
3215 * symtab.c: lint; add no_symtab_msg to consolidate the messages
3216 printed in various places, so I could change just one copy.
3218 * dbxread.c, coffread.c: Change references to bfd->iostream
3219 to cast to FILE *, now that BFD avoids needing types defined
3220 in other header files.
3222 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3224 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
3225 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
3226 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
3227 (actually gcc -Wall).
3229 * dbxread.c: Remove first_global_sym, last_global_sym, since
3230 they are never referenced.
3232 * defs.h (baud_rate): Declare.
3233 main.c: Define it, and add the -b option to set it.
3235 * gdb-int.texinfo: Add text on how to define a new host or target
3236 architecture, prompted by Per Bothner's questions about MIPS
3239 * gdb.texinfo: Document "complaints". Change doc of -q since
3240 gdb no longer prints the copyright and blurb if you specify a file
3241 name to be debugged (just like Emacs). Add doc for Nindy-specific
3242 command line flags for specifying target serial port and such.
3243 Update copyright to 1991.
3245 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
3246 has taken over for us the job of ripping up executable files. The
3247 crud caused Per Bothner's port to not compile.
3249 * infrun.c (normal_stop): Avoid printing "Program exited
3250 normally" if we are in batch mode. This allows a GDB which
3251 executes a program on a target system, to behave like a Unix
3252 command (input from stdin, output to stdout, no extraneous
3255 * main.c (main): Allow additional machine-dependent command line
3256 options to be specified with the ADDITIONAL_OPTIONS,
3257 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
3258 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
3259 processing to occur just before the main loop with
3260 BEFORE_MAIN_LOOP_HOOK.
3261 (main): If a "core file" argument is specified, and it is not a
3262 core file, try it as a process ID to attach.
3263 (symbol_completion_function): Attempt to cope with
3264 "show screen-" TAB, not very successfully. This needs more work,
3266 (batch_file): New function, returns whether we are reading
3267 commands from an interactive tty on stdin, or from somewhere else.
3268 Called by normal_stop since it doesn't get from_tty passed down
3269 to it like many commands do.
3271 * remote-nindy.c: Handle command line options for nindy
3273 (nindy_before_main_loop): Prompt user for tty name if they
3274 don't specify it before getting to the interactive command loop.
3276 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
3277 and -r command line options. Also add hook before main loop
3278 to make it easy to specify a tty.
3280 * TODO: More things to do, one done.
3282 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
3284 * dbxread.c: Make complaint() calls pass pointer, not struct.
3285 Add complaints about badly formatted C++ type information
3286 (const/volatile indicator, and parse errors resulting in
3287 error_type). Fix C++ virtual member fn comment.
3288 (read_struct_type): Avoid bumping pointer if we got a parse
3289 error; this prevents our walking beyond the end of a string.
3290 Terminate loop on null char as well as semicolon.
3291 (process_one_symbol): Fix the LBRAC fix so that it uses the
3292 last previous SLINE, FUN, or SO record's PC address. C++ debug
3293 symbols did not have SLINE records in a useful order compared
3294 to the LBRAC records.
3295 (define_symbol): Handle "catch" records.
3297 * symtab.c (check_stub_type): Added new complain
3298 `stub_noname_complain' and added a consistency check to
3299 keep the debugger from crashing when finishing from an
3300 exception frame. A real fix will be needed later.
3302 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
3304 * infcmd.c (attach_command): Make global.
3306 * Makefile.dist (REMOTE_OBS): Make these compile by default,
3307 but make them easy to comment out. Perhaps later they should
3308 be enabled by what CPU you configure for? FIXME.
3309 (VERSION): Roll to 3.93.
3310 (pinsn.o): Remove rule for obsolete file.
3311 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
3313 Run down a problem that manifested by printing the wrong function
3314 name in stack traces of read_ofile_symtab. Turned out that the
3315 problem was the SunOS 4.1.1 (and previous) C compiler outputs
3316 the LBRAC symbol with an address in the *data* segment, which
3317 blew our binary search through the blocks.
3319 * dbxread.c: Use the complain() facility consistently to bitch
3320 about problems in the symbol file we are reading.
3321 (finish_block): Add code to check the nesting of the blocks;
3322 complain and Procrust them to fit if wrong.
3323 (make_blockvector): Check the order of the blocks, complain
3324 [but don't cope] if wrong.
3325 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
3326 symbols to be sure their PC value is greater than the last SLINE
3327 (line number) symbol we've seen, complaining and adopting the
3328 SLINE PC value if wrong.
3330 * symfile.h (struct complaint, complaint_root, complain,
3331 clear_complaints): Add.
3332 * symfile.c (complain, complaint_root, clear_complaints): Add
3333 facility to deal with non-fatal complaints and to regularize their
3335 (symbol_file_add): Clear complaint counters to allow new complaints.
3336 (initialize_symfile): Add 'set complaints' and 'show complaints'.
3338 * dbxread.c (dbx_symfile_read): Remember the address and size
3339 of the string table for the main symbol file, so we won't read it
3341 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
3342 to avoid reading the string table yet again. Lint.
3343 (throughout): Improve filtered output, including word wrap.
3344 (read_range_type): Improve Bothner's fix to handle other types too.
3346 * utils.c: Improve line wrap implementation. Handle unlimited
3347 width by making chars_per_line unsigned.
3348 (puts_filtered): New, easy, function.
3350 * defs.h (puts_filtered): add.
3352 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
3353 call the identical sort_symtab_syms() in symfile.c instead.
3355 * expread.y: Suggest the `file' command rather than `symbol-file'.
3357 * command.h (enum var_types): Add zinteger for seroable
3359 * command.c (do_setshow_command): Handle var_zinteger. Restructure
3360 nested if's into a switch.
3362 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
3363 we did not stop because of a breakpoint (it must have been for
3364 some other reason, like a "stepi"), so don't print anything.
3366 * symtab.c: Include <sys/types.h> all the time. Now that BFD
3367 doesn't include <sys/types.h>, old SunOS's require it for
3370 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
3372 A test port of gdb-3.92.6 to the Sony NEWS.
3375 Don't normally link in remote- or vx stuff.
3376 Some of it doesn't compile, and it wastes space for 99% of the users.
3377 Remove reference to no-longer-used HAVE_VPRINTF.
3378 Fixed BFD_DEP typo to BFD_DIR.
3380 Fix cast in arg to bfd_h_getlong.
3381 Make char *prefix be const.
3382 Fix how certain range types are mapped into builtin unsigned int types.
3384 Remove 2 #includes. They cause errors (on Sony, at least),
3385 and aren't needed (they wern't in earlier versions).
3387 print_address_symbolic should never demangle labels
3388 (since it prints *assembler-level* labels).
3390 [This was superseded by the change to printcmd below.]
3393 Add some "volatile" return types to avoid warnings.
3394 If MISSING_VPRINTF add vprintf function and not just macro
3395 (since vprintf is used in printcmd.c).
3397 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
3398 (The latter isn't grokked by some PCC-based compilers.)
3400 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
3402 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
3403 * nindy-share/coffstrip.c
3404 Added some forward declarations (otherwise, gcc complains
3405 about implicit extern redefined as static).
3407 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
3409 Changes inspired by Per Bothner:
3410 * printcmd.c (print_address_symbolic): Take additional parameter
3411 specifying whether to demangle.
3412 (print_address): Pass in asm_demangle to control demangling.
3413 (print_address_demangle): New fn, takes explicit arg to control
3415 * utils.c: Add new vars demangle and asm_demangle, and let them
3417 (fputs_demangled): If !demangle, just print the argument.
3418 (fprint_symbol): If !demangle, just print raw symbol.
3419 * valprint.c (val_print): Call print_address_demangle rather than
3420 print_address, to cause demangling to depend on the global
3421 rather than assembler-level demangling setting.
3422 * WHATS.NEW, gdb.texinfo: Document.
3424 * main.c (show_command): Show all settings if no arg.
3425 (initialize_main): Make "info set" the same as naked "show".
3426 * command.c (cmd_show_list): Handle prefix commands in the
3427 list, and print the name of the setting as well as its English
3428 description and value.
3430 Allow gdb functions to specify where a line should wrap if it
3431 exceeds the size of a terminal line. Use it to make the output
3433 * utils.c (set_screen_width_command): New fn, mallocs a buffer
3434 of the right size when screen width changes.
3435 (set_screensize_command, screensize_info): Remove #if 0'd fns.
3436 (wrap_here): New fn, indicates a point in the output where we
3437 should wrap the line rather than just letting it overflow at a
3439 (fputs_filtered): Implement wrapping.
3440 (n_spaces): New fn, returns a pointer to N spaces.
3441 (print_spaces_filtered): Use n_spaces.
3442 * defs.h (n_spaces): Declare.
3443 * stack.c (print_frame_info): Wrap with 4-space indent after
3444 fn name and before filename and line number.
3445 * printcmd.c (print_frame_args): Wrap with 4-space indent
3446 before each argument name is printed.
3447 * valprint.c (value_print): Wrap with no indentation before
3449 (val_print_fields): Wrap with indentation relative to nesting
3450 level before each field name.
3451 (val_print): Wrap with nesting indentation before array elements.
3452 * command.c (do_setshow_command): Avoid extra newlines,
3453 wrap with 4-space indent around values printed, end with period.
3454 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
3456 * breakpoint.c (breakpoint_1): Implement addressprint for
3457 "info breakpoints" display. Change file name and line number
3458 format to " at file:nnn" rather than " (file line nnn)".
3459 * gdb.texinfo: Document.
3462 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3464 Frozen for gdb-3.92.6 release.
3466 README, WHATS.NEW: Update for 3.92.6 release.
3468 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
3469 coffread.o from configs since it is now built by default.
3470 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
3471 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
3472 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
3473 from configs since it is now built by default.
3475 Makefile.dist: Update for release 3.92.6. Handle files that
3476 have been moved to ../include, ../getopt, or ../bfd. Add
3477 saber.suppress and tests directory. Add config.status to
3478 the release (it will say "none").
3480 coredep.c: Minor formatting fixes.
3482 These changes were made in early December but only checked in now:
3483 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
3484 nindy-share/nindy.c: lint
3485 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
3486 register values coming back from the target; we store values
3487 in target byte order everywhere.
3489 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
3491 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
3493 * valprint.c (cplus_val_print, val_print_fields): New functions,
3494 which print C++ objects. They conspire to avoid printing a
3495 virtual base class more than once, following all the twists and
3496 turns of C++ virtual base rules.
3497 (val_print): Call the above rather than do it by hand.
3499 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
3500 symbol file, not for added files like shared libs. This really
3501 needs to be generalized to a timestamp per file.
3503 * core.c (cleanup_core): Avoid coredump if no core file.
3505 * config.gdb: Accept -host or -target in place of +host or
3508 * coffread.c (find_linenos): Avoid desupported BFD interface
3509 to line numbers. We still read them manually rather than using
3510 BFD's "generic" features.
3512 * gdbrc.tex, threecol.tex: Add GDB reference card and its
3514 Makefile.dist: Add refcard to OTHERS list for creating tar files.
3516 * Makefile.dist: Eliminate use of $< in explicit targets.
3518 * readline/Makefile: Use $< rather than $*.c, which does not
3519 include the VPATH in GNU Make.
3521 * tconfig/i960-bout, tconfig/i960-coff: These are identical
3522 copies of tconfig/i960, added for global configuration
3523 compatability. All i960 versions can read both coff and b.out.
3525 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
3526 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
3529 * TODO: Think of more things to do.
3531 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
3533 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
3534 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
3535 64-bit float conversion.
3537 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
3538 equivalent to sun?os4 so global config works.
3540 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
3542 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
3544 * main.c: Only declare linesize once; declare pagesize not at
3545 all, since it is never used.
3546 (main): Clear newly allocated line before it is used.
3548 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
3550 Further stabilization for the Intel 960.
3552 * Makefile.dist: Parameterize the location of the "include"
3553 and "bfd" directories, as well as "getopt". Add symfile.c.
3554 Link in both dbxread and coffread. Fix up "make depend" to
3555 rewack the locations of include, bfd, and getopt in its output.
3557 * README: Document moving include files, improve some of
3560 * coffread.c: Move common code out to symfile.c. Change
3561 symbol_file_command style interface to use new *_symfile_init
3562 and *_symfile_read interface under BFD. Use BFD internal
3563 info to locate line table, symbols, etc.
3565 * core.c (core_fetch_registers): Rename to get_core_registers
3566 to avoid confusion with fetch_core_registers.
3567 (register_addr): Move to coredep.c, which is already machine
3568 dependent. This leaves core.c pretty clean of dependencies.
3570 * coredep.c (register_addr): Accept this routine from core.c.
3572 * dbxread.c: Move common code (with coffread.c, etc) into new
3573 symfile.c. Each psymtab now contains a pointer to the
3574 format-dependent function that knows how to read it in. Make
3576 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
3577 (process_one_symbol): Add code to complain about a "compiler bug
3578 we muzzle here", if we actually see it.
3580 * eval.c (evaluate_subexp): Insert missing "break" statements
3581 in code that determines whether a variable is an lvalue in
3582 memory, register, or whatever. I detected this via a compiler
3583 bug in which it *almost* mashed out the whole switch statement.
3585 * gdb-int.texinfo: Add minor sections on configuring gdb for
3586 release, and about the README file.
3588 * infcmd.c (registers_info): Fix formatting somewhat. Still
3589 not as pretty as before, but it handles byte swapping.
3591 * remote-nindy.c: If data cache routines are interrupted while
3592 waiting for the remote end, be sure that any uninitialized cache
3593 blocks are on the free list, not on the valid list!
3595 * symfile.h: Flesh out this header file with all the various
3596 routines and variables that have been merged in from dbxread.c
3597 coffread.c, and symtab.c to symfile.c.
3599 * symfile.c: New file, containing code common to dbxread.c,
3600 coffread.c, and some code from symtab.c. All generic code for
3601 reading symbol files should be in here now.
3602 (unrecord_misc_function): Remove unused function.
3604 * symtab.h: Remove file-reading things to symfile.h.
3606 * symtab.c: Remove file-reading things to symfile.c.
3608 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
3609 to decode i960 fault types.
3611 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
3612 target.c: Change type of the "resume" function from int to void,
3613 since its result was never used.
3615 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
3617 * main.c: Replace "stupid" with "caution"; you now "set caution
3620 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
3622 * infcmd.c (do_registers_info): Call val_print to deal with the
3623 byte order of the registers being printed. FIXME, this makes
3624 the formatting of the output uglier.
3626 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
3627 defined, call it for signals the debugger doesn't itself use.
3628 The i960 uses this for more detailed fault information.
3630 * remote.c (remote_open): If arg is null, print help rather than
3633 * sparc-xdep.c (register_valid): Avoid declaring size, since
3634 various modules will think of various sizes depending on the
3635 architecture of their tm-file. FIXME, we need protection against
3636 actually entering one of those modules, which would clobber
3637 storage if not for the target architecture compiled into gdb.
3639 * stack.c (up_command, down_command): Always print the frame
3641 (up_silently_command, down_silently_command): New commands
3644 * i960-pinsn.c (reg), i960-tdep.c: Lint.
3646 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
3647 more parameters than it used to.
3649 * findvar.c (registers): Increase slop to 256 bytes, which should
3650 protect us against even most RISC machines with large register
3652 (locate_var_value): Move declaration inside related ifdef.
3654 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
3655 throughout, to avoid throwing away buffered input from the board.
3656 (nindy_wait): Supply_register takes addr_of_value, not value.
3657 (i960_print_fault): Renamed from i80960_fault.
3658 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
3659 (nindy_store_registers): Avoid regs_changed stuff, just stuff
3661 (nindy_create_inferior): Don't bother to write PC_REGNUM since
3662 we can set the PC in the call to proceed(). Unpush nindy_ops
3663 before pushing it on top, to avoid message to user. Eliminate
3664 commentary from Unix machines that just misleads here.
3665 (reset_command): Fix error message to suggest target command.
3667 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
3669 Release 3.92.5 as frozen.
3671 Stabilize the merged release...with help from lint, Saber C,
3674 Everywhere: Add include files needed to declare return types
3675 of functions called.
3677 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
3679 * breakpoint.h: Add undeclared breakpoint functions, and some
3680 functions for display handling since I couldn't think of a better
3683 * breakpoint.c (insert_breakpoints): Make code for disabling
3684 shared library bkpts more likely to work. It's used when we
3685 rerun a program and stop before the shared library has been
3687 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
3688 cast from pointer, so it squeezes through catch_errors.
3689 (bpstat_stop_status): Fix logic broken some time ago. We now
3690 always create a bpstat if the stop address matches a breakpoint,
3691 even if we don't stop there -- just like the old code used to do
3692 before I got my fingers into it (sigh).
3693 (breakpoint_1): Print "ignore count" after "stop only if"
3694 condition, since that's how it actually works.
3695 (mention): Handle watchpoints as well as breakpoints.
3696 (watch_command): use set_raw_breakpoint and mention to do most
3697 of the work (and initialize all the fields!). Only pass one
3698 arg to parse_c_expression, since that's all it takes.
3700 * command.c (not_just_help_class_command): Rename arg to args
3701 since we ignore "unused argument" warnings on vars named "args".
3702 inflow.c (child_terminal_info): ditto.
3703 infptrace.c (kill_inferior): ditto
3704 main.c (catch_errors, version_info, quit_command, pwd_command,
3705 source_command, dump_me_command, editing_info,
3706 set_history_size_command, set_history, show_history,
3708 stack.c (locals_info): ditto
3709 target.c (target_files_info): ditto
3710 valprint.c (set_input_radix, set_output_radix): ditto
3712 * core.c: Remove old variables for handling core and exec file
3713 sections (data_start, data_end, stack_start, stack_end,
3714 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
3715 text_end, exec_data_start, exec_data_end, text_offset,
3716 exec_data_offset, data_offset, stack_offset). They're
3717 superseded the more general build_section_table and
3719 (get_exec_file): Mention the `file' command.
3720 (read_memory_check): Rename to memory_error, and only call it
3721 in the case of an actual error.
3722 (read_memory, write_memory): call memory_error.
3723 (core_fetch_registers): Register section name is ".reg".
3725 coredep.c: Remove a bunch of crud now that all this file does
3726 is pull the registers out of a core file.
3727 (fetch_core_registers): Rewrite to actually work, I hope.
3729 dbxread.c: Use a.out.gnu.h, not system a.out, now.
3730 Replace index() with strchr(). Remove all the pre-BFD macro
3731 definitions for accessing the symbol file.
3732 (struct dbx_symfile_info): Encapsulate the information that
3733 dbx_symfile_init needs to pass to dbx_symfile_read in this
3736 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
3737 dbx_symfile_discard): Rearrange symbol file reading to divide
3738 the format-specific part from the format-independent part,
3739 leaving the format-independent part such as file name expansion
3740 and opening in symtab.c. This replaces
3741 partial_symbol_file_open and partial_symbol_file_read.
3742 Symbol_file_read, add_file, add_file_target_command,
3743 add_file_addr_command move to symtab.c. Pass an explicit
3744 "mainline" flag for when reading the main symbol table, rather
3745 than relying on the offset address to be zero or nonzero.
3747 (dbx_symfile_read): Don't allow void *'s to be printed as
3749 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
3750 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
3751 macro" debug version really work.
3752 (read_dbx_symtab): Remove unref'd parameter inclink.
3753 Avoid swapping N_SLINE symbols, for speed.
3754 Merge N_TEXT!N_EXT case with the other external symbol
3755 definitions' case. Add comments.
3756 (start_psymtab): Allocate the symfile name in the psymtab on
3757 the psymbol_obstack, rather than using the caller's storage.
3758 (end_psymtab): Only allocate a dependencies list if there are
3760 (psymtab_to_symtab_2): Use BFD when reopening file to read
3761 its symbols for real.
3762 (read_struct_type): Add FIXME comments where it needs work
3764 (read_huge_number): Add FIXME about overflows.
3765 (read_range_type): Add FIXME about comparing a long to 1<<32.
3767 * coffread.c: Minor changes to move things closer to the new
3768 regime with symtab.c and dbxread.c Major work is still needed
3771 * exec.c (exec_file_command): Remove old variables (see core.c
3773 (xfer_memory): If memory transfer is right at the end of a
3774 section, don't lose.
3776 * findvar.c (get_saved_register): If value is in a real
3777 register, LVAL is lval_register, not lval_memory.
3779 frame.h: Declare print_sel_frame and record_selected_frame.
3781 gdb-int.texinfo: New file, for GDB internals documentation.
3782 Very simple, unformatted doc of cleanups is there for now.
3784 gdbcore.h: Remove obsolete variables that described a.out
3785 section addresses and offsets. (See core.c above.)
3786 Declare fetch_core_registers and registers_fetched.
3788 getopt.c: Declare char *alloca(); even on SPARC.
3790 infcmd.c (run_command): Call target_kill rather than
3792 (step_command, next_command, stepi_command, nexti_command):
3793 Declare from_tty parameter even though we don't use it.
3794 (run_stack_dummy): argument BUFFER is a char array, not
3795 a pointer to REGISTER_TYPE.
3796 (finish_command): using_struct_return needed a value *,
3797 not a struct symbol *.
3799 * infptrace.c (child_xfer_memory): To avoid dependency on
3800 where sections are in memory, try PT_WRITE_D and if that fails,
3801 try PT_WRITE_I. Most Unixes don't care which you use.
3803 * infrun.c (step_resume_break_shadow): Change to array to
3804 match other breakpoint shadow storage.
3805 (clear_proceed_status): Pass address of bpstat to
3806 bpstat_clear, not the bpstat itself.
3807 (child_create_inferior): FIXME comment about if the child
3809 (start_inferior): Remove old function.
3810 (child_open): Use target_kill rather than kill_inferior.
3811 (wait_for_inferior): Ditto.
3812 (insert_step_breakpoint, remote_step_breakpoint): Use
3813 new step_resume_break_shadow.
3815 * inftarg.c (child_wait): If all child processes die,
3816 pretend that the one being waited for exited with signal 42.
3818 * main.c (command_line_input): When scanning for comments,
3819 don't coredump on unclosed quotes.
3820 (quit_command): Use target_kill rther than kill_inferior.
3821 (_initialize_main): Rename class_user from "user" to
3824 * printcmd.c (print_command_1): Initialize "fmt" if no format
3825 is specified by the user.
3826 (print_frame_args): Only add to args_printed if we are
3827 actually fetching args from the stack (avoiding undefined
3829 (_initialize_printcmd): Remove bogus \{ from string.
3831 * remote-eb.c (eb_open): Avoid coredump on no argument.
3833 * remote-nindy.c: Bring out of Intel environment into new
3834 target environment. Remove all conditional compilation on
3835 I80960. Massive hacking throughout.
3836 (nindy_xfer_inferior_memory): New routine stolen from
3838 (nindy_create_inferior): New routine pieced together, probably
3839 not quite working yet.
3840 (nindy_ops): New target_ops struct for nindy.
3842 * remote-vx.c: Use write_memory rather than target_write_memory
3843 to get error checking.
3844 (vx_add_file_command, vx_open): Use symbol_file_add rather than
3846 (vx_create_inferior): Use target_terminal_ours...
3848 * signame.c (_initialize_signame): Always initialize, since
3849 we need the table for things other than psignal.
3851 * solib.c (solib_add): Use symbol_file_add, not add_file.
3852 (solib_address): Return boolean result rather than struct
3853 pointer which nobody else knows the type of.
3855 * sparc-tdep.c, valops.c: Use write_memory rather than
3856 target_write_memory, to get error checking.
3858 * stack.c (locals_info, catch_info, args_info,
3859 get_selected_block, frame_command, up_command): Use
3860 target_has_stack, rather than have_inferior_p or
3863 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
3865 * symfile.h: New file, defining the interface between the
3866 generic and object-file-specific symbol reading code.
3868 * symtab.c: Move generic symbol-reading interface to symtab.c,
3869 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
3870 table to map BFD targets to symbol-reading modules in GDB.
3871 Change index to strchr.
3872 (lookup_struct_elt_type): Use error() rather than hand-made
3873 simulations thereof.
3874 (lookup_partial_symbol): Speedup slightly when length == 0.
3875 (symbol_file_add): New function.
3876 (symbol_file_command): Call it.
3877 (symfile_open, symfile_init): New function.
3878 (add_file_target_command, add_file_addr_command): moved from
3881 * target.c (target_command): use target_kill.
3883 * target.h (target_files_info): Don't declare, never called
3886 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
3887 files to determine stack end address.
3889 * valarith.c (value_x_binop, value_x_unop): Change error message
3890 to be more useful. Pass proper argument to value_struct_elt.
3892 * valops.c (value_assign): FIXME comment that long long
3893 bitfields will break here.
3895 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
3896 Update `make saber_gdb' to work better.
3898 * TODO: A woman's work is never done.
3900 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
3901 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
3902 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
3903 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
3904 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
3905 valops.c, valprint.c, exec.c: Lint.
3908 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
3910 Continuing Intel 960 port merge of GDB.
3912 * Makefile.dist: Merge i960 "nindy-share" files. Rename
3913 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
3914 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
3915 Wack over "make depend" so it handles files in subdirectories
3916 vx-share, nindy-share, bfd, and in the current directory.
3918 * blockframe.c (get_prev_frame_info): Remove fatal error
3919 if stack not defined.
3921 * core.c (core_open, core_detach): New functions that handle
3922 the old "core-file" command as "target core" and "detach" instead.
3923 (core_file_command): Call them.
3924 (core_xfer_memory): Use common routine xfer_memory.
3926 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
3927 dbxread now uses bfd for everything but symbol reading itself.
3928 BFD internals are used to drag out the relevant file offsets.
3929 (partial_symbol_file_open): Change args all around for BFD.
3931 * symtab.c: Rename "value" to "val" everywhere, so we can
3933 (symbol_file_command): New command, moved from dbxread.c
3934 and coffread.c. It uses BFD to read the file, then vectors
3935 based on its type, to dbx or coff symbol readers.
3936 * symtab.h: Extern a few vars for symbol_file_command.
3938 * target.h: Breakpoint takes a char * save area, not a char **.
3940 * valprint.c (val_print): When unpacking bitfields, offset
3941 the address in gdb of the value, if it is declared with a shorter
3942 type. Remove the last "runtime kludge test" of host byte order.
3944 * utils.c: Remove old my_bfd_read routine.
3946 * stack.c (frame_info): Use target_has_stack. Print program counter
3947 register's actual name rather than "pc", since it's called the
3948 "ip" (instruction pointer) on the i960 (sigh).
3950 * target.c (target_command): Add command for selecting a target
3951 type and calling its open routine. This is used for initiating
3952 communication with a particular target, in a generic way.
3954 * tm-i960.h: Update for modern gdb. Remove semicolons from
3955 various macros. Handle reading struct return convention, and
3956 error-out attempts to return structs with the "return" command.
3957 Be sure gdb doesn't think we know how to call functions in the
3960 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
3961 to i960_xxx in lower case.
3962 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
3963 not being defined yet.
3965 * remote.c (remote_open): Call start_remote to initialize
3966 wait_for_inferior during open.
3967 (remote_xfer_inferior_memory): Return length written rather
3970 * remote-vx.c (target_command -> vx_open): Use new generic
3972 * remote-eb.c, inftarg.c, exec.c: ditto.
3974 * infrun.c: Fix comments.
3975 (attach_program -> child_open): Use new generic target command.
3976 (wait_for_inferior): Clear saved register values before target_wait,
3977 so target_wait can set some of them if convenient.
3979 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
3980 Return success indicator, not void.
3981 (child_xfer_memory): Avoid fetching initial word if we'll
3982 overwrite it anyway.
3984 * infcmd.c (attach_command): Use new generic target open routine.
3985 (_initialize_infcmd): Update doc on attach and detach commands.
3986 (do_registers_info): Merge in a byte-order problem as a FIXME
3989 * findvar.c (find_saved_register): Avoid problem in current frame.
3990 (read_relative_register): Ditto.
3991 (write_register): Convert byte order on the way out.
3993 * exec.c (file_command): Add.
3994 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
3995 (xfer_memory): Common function between core_xfer_memory and
3997 (exec_xfer_memory): Use it.
3999 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
4001 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
4002 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
4003 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
4005 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
4007 Merge Intel 960 port of gdb, continuing...
4009 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
4010 symbol_file_command): Pass from_tty arg to hush 'em up.
4012 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
4013 Add magic numbers for 960 COFF format.
4015 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
4017 Merge Intel 960 port of gdb, from Intel "1.2" release.

4030 Tue May 29 12:54:49 PDT 1990
4031 Added variable baud rate (-b switch).
4032 Source code reorganization.
4034 Thu Apr 26 11:09:55 PDT 1990
4035 More cleanup of batch mode; specifically, execute "-s", "-e", and
4036 "-se" switches as soon as they are encountered on the invocation line.
4038 Fri Apr 20 13:47:15 PDT 1990
4041 Thu Apr 19 09:54:28 PDT 1990
4042 Add 'reset' command.
4044 Wed Apr 18 09:48:07 PDT 1990
4045 After opening remote tty, wait for 1 second to go by without input
4046 from it before trying to talk to NINDY (fixes problems with the
4047 Heurikon HK80/V960E).
4049 Mon Apr 4 16:33:05 PDT 1990
4050 Some output was not being suppressed in 'batch' mode.
4052 Thu Mar 22 15:31:11 PST 1990
4053 Ask user if old symbol table should be deleted when new file is
4056 Allow user to run a program downloaded before gdb960 was brought up.
4058 Correct "exec-file" help message for i80960 context.
4060 Correct bug in calculating user space address: could occasionally
4061 corrupt user program.
4063 Make sure to zero low-order bits in rip's because of bug in 960CA
4064 A-step part: could cause operation faults when "next"ing across
4067 Correct bug that made it impossible to get source line numbers for
4068 code loaded at addresses higher than 0x7fffffff.
4070 Wed Jan 10 12:43:22 PST 1990
4071 Open remote tty for exclusive use.
4073 Fri Jan 5 12:14:42 PST 1990
4074 Correct disassembly (CA manual was right after all):
4075 opcode for sysctl is 0x659
4077 Mon Oct 23 12:03:04 PDT 1989
4078 Use G960BASE and G960BIN environment variables to find 'sx' utility.
4080 Mon Oct 16 14:15:09 PDT 1989
4081 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
4083 Mon Oct 2 15:56:31 PDT 1989
4085 Added 960CA disassembly support.
4087 To simplify maintenance:
4088 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
4090 - eliminated opcode.h: incorporates tables into i960-pinsn.c
4091 - moved 960-specific routines from i960-pinsn.c to i960-md.c
4092 - made disassembly interface identical to that in gdmp960.
4096 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
4098 * target.h: Allow targets to stack. Add target_has_memory,
4099 _registers, etc. Restructure memory access and "info files"
4100 to walk the target stack.
4101 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
4102 target.c: Change tables to match target.h.
4103 * inflow.c (child_mourn_inferior): pop child_ops.
4104 (generic_mourn_inferior): Use new has_stack flag.
4105 * infptrace.c (child_xfer_memory): New memory regime.
4106 * inftarg.c (child_files_info): New "info files" regime.
4107 * remote-eb.c: New memory regime, new info files.
4108 * remote-vx.c: New memory regime, new info files. Now use
4109 separate targets for VxWorks attachment to machine, and
4110 actually running a process under VxWorks, since one has
4111 stack & execution & regs and the other doesn't.
4112 * remote.c: New memory regime, new info files.
4113 * sparc-xdep.c (fetch_core-registers): New memory regime.
4114 * target.c: New routines and support for stacked targets,
4115 new memory regime, new info files regime.
4118 Generalize section handling for an arbitrary number of sections,
4119 including use of the new BFD (binary file) library.
4120 * gdbcore.h: Add struct section_table.
4121 * exec.c (build_section_table): Iterate all sections and
4122 record what gdb needs to know about them.
4123 (exec_command): Use it.
4124 (exec_xfer_memory): Use the table.
4125 (exec_files_info): Print the table.
4126 * core.c (core_file_command, core_xfer_memory, core_files_info):
4128 * source.c (find_source_lines): Use bfd_get_mtime.
4129 * dbxread.c: Quick changes to make it compile with new BFD.
4130 * utils.c (error): Avoid using bfd_error in generic routines.
4132 * core.c (core_fetch_registers): Get from the ".regs" section of
4134 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
4136 * inferior.h (attach_flag): Export.
4137 * infcmd.c (run_command): use new target_create_inferior.
4138 * infrun.c (child_create_inferior): Don't return result.
4139 * Makefile.dist (VERSION): 3.91.4.
4141 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
4143 * breakpoint.c (bpstat_num): Handle breakpoints which have
4144 since been deleted, such as temporary breakpoints.
4145 infcmd.c (program_info): ditto.
4147 * core.c (core_file_command): Display the frame where the core
4152 * remote-vx.c (target_command): Merge in target command from
4153 targ-vx.c. A few other cleanups.
4155 * TODO, Projects: Lots more stuff to do...
4157 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
4159 Massive changes to wall off the remote-debugging interface
4160 behind a function vector. The port to handle VxWorks targets
4161 is also part of this.
4163 All files: Replace references to renamed functions,
4164 remove references to remote_debugging, remove references to
4165 have_include_file, have_core_file in favor of target_has_stack,
4166 target_has_memory, etc.
4168 * Modularize the breakpoint interface.
4169 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
4170 a breakpoint instruction.
4171 breakpoint.c: struct breakpoint's shadow_contents now sized as
4173 (insert_breakpoints): Vector to target to install breakpoints.
4174 (remove_breakpoints): Vector to target here too.
4175 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
4176 sparc-tdep.c (single_step): Use new breakpoint interface for
4177 the single-step breakpoints.
4178 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
4179 New file, contains routines to insert and remove breakpoints by
4180 reading out the old contents and later replacing them. This is
4181 how ptrace breakpoints work, and many remote systems as well.
4183 * tm-vxworks68.h: New config file, overrides a few things for
4184 Wind River's preferences.
4186 * target.h: New file, for transfer vector used to talk to the
4187 inferior (child, attached, core, exec, remote, etc). All accesses
4188 to the thing being debugged should come through these vectors.
4189 target.c: New file, routines to handle transfer vector.
4190 (various files): Add transfer vectors XXX_ops for the various
4191 targets and pseudo-targets (core files, etc) we support.
4193 * breakpoint.c (bpstat_stop_status): Further explorations of
4194 watchpoints and why things don't work all the time.
4195 (bpstat_alloc): New fn to allocate a bpstat and chain it.
4197 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
4198 the local gdbinit if it doesn't already have it.
4200 * core.c (core_ops): add and install.
4201 Allow core debugging without exec file.
4203 * dbxread.c (free_and_init_header_files): Merge two fns.
4204 (end_symtab): Free named symbol table when a new version comes in.
4205 (read_dbx_symtab): Relocate all kinds of symbols with base
4206 address. First step toward handling different text, data, bss
4208 (add_file_addr_command): Renamed add_file_command.
4209 (add_file_command): Vector to remote handler.
4210 Add "load" as an alias for "add-file" command.
4212 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
4213 non-returning functions.
4215 * exec.c: Add exec_ops, and push it as a target when an exec
4218 * infcmd.c (run_command): Pass executable file name and arg list
4219 separately when starting an inferior. Permit "run" when no exec
4220 file is specified, for VxWorks.
4221 (detach_command): Move to child_detach in inftarg.c.
4223 * inftarg.c: New file. Unix-child-specific routines, and the
4224 child_ops structure.
4226 * inferior.h (registers): Export "registers" as the way for
4227 target dependent register handlers to find gdb's local copy of
4228 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
4229 since it is now used by places that want wait_for_inferior to
4230 handle the grunge but want to see every trap from the inferior.
4232 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
4233 Eliminate remote_debugging hooks in terminal handling.
4235 * infrun.c: Replace start_inferior with child_create_inferior.
4236 Move all the hair of Unix shells and ptrace idiosyncracies into
4237 child_create_inferior, so remote handlers don't have to deal.
4238 Remove running_in_shell. Rename stop_after_attach to
4239 stop_soon_quietly, and use it in a few other places where we want
4240 to just call wait_for_inferior and get control back on the first
4241 trap. trap_expected now never takes a value > 1.
4242 (init_wait_for_inferior): Initialize static vars when a new
4245 main.c (gdbinit): Add new hook for .gdbinit file name, let
4246 it be overridden by config files as GDBINIT_FILENAME.
4247 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
4248 Both of these are used for VxWorks gdb.
4250 mcheck.c: rename include file "gmalloc.c" to avoid problems
4251 with system include file "malloc.c".
4253 param-no-tm.h: New include file, same as param.h but does not
4254 include the default "tm.h" file. This is used in files where
4255 the target is known, e.g. remote-eb.c or sparc-xdep.c.
4257 param.h: Now just a shell that includes tm.h and param-no-tm.h.
4259 remote-vx.c: New file, VxWorks remote debugging support. Uses
4260 RPC routines that are shared with the target system, in directory
4263 remote.c: Vectorize remote interface.
4265 source.c: Globalize source_path, and make an alias "l" for "list"
4266 since we now have the "load" command.
4268 sparc-xdep.c: Use new param-no-tm.h.
4270 symmisc.c (free_named_symtab): Add new function from Wind River.
4271 However, ifdef it out for now while we think about what it should
4274 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
4276 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
4277 non-Unix-children handle this with their own code in the target
4280 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
4281 source and target lists. Add vx-share to default list of include
4282 directories. Add new files to src and target lists: mem-break,
4283 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
4284 ${srcdir} versions of munch and createtags are used.
4286 * valops.c (find_function_addr): Split out of call_function.
4287 (call_function_by_hand): Rename call_function; this function
4288 calls functions in the target by laboriously patching the target
4289 word-by-word with the right stack, args, regs, etc.
4292 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
4294 Handle AMD 29000 a bit better.
4296 * remote-eb.c (readchar): Mask received char log to make it readable.
4297 (remote_start): Pass arguments down to executing program.
4298 Make startaddr unsigned.
4299 infrun.c (start_inferior): Accept args, pass them to
4301 infcmd.c (run_command): Pass args down to start_inferior.
4303 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
4304 the target object file format.
4305 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
4307 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
4308 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
4310 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
4312 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
4313 * TODO: We did a few things, we have more to do though.
4315 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
4316 * inflow.c (inferior_died): Clear deferred stores.
4318 * Debug problems with dummy frames and calls to the inferior.

4320 * sparc-tdep.c (do_restore_insn): Simplify.
4321 (sparc_frame_find_saved_regs): Simplify and fix what we find.
4322 (sparc_push_dummy_frame): Simplify and fix what we push.
4323 (sparc_pop_frame): Slightly more hair here, deciding whether
4324 we are restoring a saved PC or returning to a return address in %i7.
4325 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
4327 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
4328 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
4329 * obstack.h (chunkfun): ditto.
4330 * defs.h (xmalloc, xrealloc): ditto
4332 * utils.c (quit): Grab the terminal from the child if necessary.
4334 * inflow.c (term_status_command): Rename to term_info, change
4337 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
4338 (is_delayed_branch): Speed up.
4339 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
4340 Still missing some float ops, and needs testing.
4342 * Support for input and output radixes other than base 10
4343 * defs.h (input_radix, output_radix): Declare.
4344 * expread.y (yyparse, parse_number): Handle changes of input
4345 radix, and ambiguous names-or-numbers in radixes >10.
4346 * printcmd.c (print_scalar_formatted): Print formatted hex
4347 numbers in varying column widths.
4348 * valprint.c (val_print): Use output_format to print scalar ints.
4349 (set_input_radix, set_output_radix, set_radix): Create.
4350 (set_output_radix): Set output_format from output_radix.
4351 (_initialize_valprint): add `set radix' but leave the others off.
4353 * main.c (execute_command): Let stupid questions be turned off.
4354 (_initialize_main): Handle "set stupidity", etc.
4356 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
4357 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
4359 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
4361 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
4362 bfd stuff is still screwed up, but with some manual work, it
4365 * breakpoint.c (bpstat_do_actions): Start over if a command
4366 proceeds the inferior, since the inferior will have stopped and
4367 will need to have its new stop-actions taken care of.
4369 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
4370 compiler fits, simplify it.
4372 * gdb.texinfo (directory command): Doc new dir command.
4373 source.c (directory_command): "dir" now puts things on the front
4374 of the path, moves dups up front, and handles multiple names
4375 on the command line, inserting each one in order. It also
4376 blows away cached line and full_filename info.
4378 * stack.c (backtrace_command): Skip "more stack frames follow"
4381 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
4382 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
4383 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
4384 The only odd one was Gould NP1, which had defined vprintf to
4387 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
4388 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
4389 variable, inspect_it.
4390 valprint.c (print_string, val_print): Use the global inspect_it
4391 to indicate whether to print in Epoch style or normal style.
4393 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
4395 * printcmd.c (call_command): add an alias for the "print" command
4396 which runs expressions and doesn't print the result if void.
4397 (print_command_1): implement it.
4399 * command.c: Remove #if 0'd code. Initialize all the fields
4400 in add_cmd (). Rename do_nothing_command to
4401 not_just_help_class_command, and make it externally visible.
4402 command.h: add user_commands to struct.
4403 * main.c (define_command): Don't overload c->function with a char
4404 string as well as a function pointer.
4406 * eval.c (evaluate_subexp): Reinstall tiemann changes to
4407 calling convention of value_struct_elt () that got dropped in
4410 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
4411 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
4413 * tm-sparc.h (POP_FRAME): replace some constants with defines.
4415 * sparc-xdep.c (store_inferior_registers): defer stores to regs
4416 until a good time (e.g. when we are about to run the child),
4417 saving ptrace calls.
4418 * infrun.c (proceed): handle DO_DEFERRED_STORES.
4419 * tm-sparc.h: define DO_DEFERRED_STORES.
4421 * sparc-xdep.c (store_inferior_registers): when storing float
4422 registers, don't store stack regs too. When storing the SP,
4423 however, DO store the stack regs too. This fixes a bug in which
4424 the dummy frame is not recognized when a call_function finishes,
4425 because its frame pointer (in the stack regs) was never
4427 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
4428 even though we don't know how to read them from an inferior.
4429 valops.c (call_function): Comment about storing SP.
4431 * infrun.c (save_inferior_status): Save away the original bpstat
4432 chain so it can be restored later. Install the copied version for
4433 use by whoever saved the status. It will be blow away by
4434 restore_inferior_status, and the original chain restored. This is
4435 important for people who have pointers into the original.
4437 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
4438 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
4439 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
4442 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
4444 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
4445 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
4446 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
4448 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
4450 * Merge Mike Tiemann's multiple inheritance changes from Sun.
4451 Store the baseclasses in a type struct starting from array element
4452 0 rather than from the unusual array element 1.
4454 dbxread.c: the above.
4455 (virtual_context): Add
4456 Read new debug information about which virtual function table
4457 a virtual function is from, and store it in fn_field.fcontext.
4459 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
4460 TYPE_FN_FIELD_STATIC_P.
4462 symtab.c: the above.
4463 valops.c: the above. Handle pointer casts of object *'s.
4464 (search_struct_method): Add.
4465 (value_struct_elt): First arg is now a pointer to a value, and is
4468 valprint.c: the above.
4469 values.c (value_virtual_fn_field): Add type arg. Handle
4470 offsetting to the proper object when calling virtual fns.
4472 (baseclass_addr): Add valuep arg.
4474 * README: Document the current state of BFD config (missing).
4475 * TODO, ChangeLog, Makefile.dist: Roll version.
4476 * WHATS.NEW: Add summary of changes since 3.5.
4478 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
4480 * dbxread.c (read_struct_type): Clear bit vectors whenever
4482 symtab.c (B_CLRALL): define.
4484 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
4485 using == rather than =. Huh... This fixes the dreaded problem
4486 wherein builtin_type_int becomes TYPE_CODE_FLT.
4488 * core.c (info_files): Show the inferior pid.
4490 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
4491 already knows how to look in the source directory.
4493 * Remove psymtab hair from many places. Remove duplicated code
4494 for searching symbol tables. Hide psymtabs from most places.
4495 Make it fast to get from a psymtab to its symtab.
4497 blockframe.c (blockvector_for_pc): Remove psymtab hair.
4498 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4499 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4500 dbxread.c: export psymtab_to_symtab, make it work if called N times.
4501 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
4502 new symtab completely. New psymtabs get symtab pointer
4503 initialized to zero. Remove MI warning printf.
4504 symtab.h: Comments. Add psymtab to symtab pointer.
4505 (PSYMTAB_TO_SYMTAB): New macro.
4506 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
4507 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
4509 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
4511 (print_frame_info): Avoid special-casing symbols that have not yet
4514 * source.c (open_source_file): Quick path if we have already
4515 located the source file by its full name.
4517 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
4518 find_pc_psymtab. When a name is found in the misc function
4519 vector, search the symbol table for its mangled name, not the
4520 name that the user typed.
4522 * bfd.h: Fix missing comment terminators, make #endifs match.
4524 * valarith.c (value_less): Handle unsigned int comparisons.
4525 Add FIXME about pointer compares, which assume host and target
4526 pointers are the same.
4528 * command.c (do_nothing_command): lint
4529 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
4530 fix comments on debug symbol format for visibility. Actually set
4531 visibility of symbols.
4532 main.c (echo_command): lint; use <readline/history.h>.
4533 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
4534 obstack.h (_obstack_blank): Rearrange pointer math to avoid
4535 pointing past end of allocated memory; saber complains.
4536 obstack.h: Declare the external functions that we use.
4537 valarith.h: use <string.h>
4538 solib.c (solib_add): lint.
4540 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
4542 * main.c (initialize_main): Default info_verbose to off, now that
4543 symbol reading is fast.
4544 (quit_command): Avoid clobbering exec_bfd while quitting.
4546 * Initial BFD (binary file diddling library) merger:
4547 coffread.c: Change AOUTHDR to struct exe_hdr.
4549 core.c: initialize initialized data at compile time.
4550 (core_file_command): Move from coredep.c, convert to bfd.
4551 (xfer_core_file): Convert to bfd.
4552 exec.c (exec_file_command): use bfd routines.
4554 mips-tdep.c: Remove exec_file_command and friends.
4557 * coredep.c: (fetch_core_registers) Convert core_file_command to
4558 fetch_core_registers.
4559 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
4561 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
4562 (my_bfd_read): More bogosity, which I don't think we call.
4563 (program_name): Remove this atrocity asap!
4565 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
4568 values.c: allocate_repeat_value was not clearing the
4569 optimized_out field.
4570 (value_static_field): minor stylistic fix (wrong macro was used).
4571 valops.c (value_struct_elt_for_address): didn't work for C++
4574 * signame.c (_initialize_signame): Initialize signal names once.
4576 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
4577 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
4578 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
4580 * remote-eb.c: Support user-settable baud rates on the serial port.
4582 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
4584 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
4586 * tconfig/sun3os4: Remove warning about native assembler,
4587 since it also occurs in the xconfig file.
4589 * findvar.c (registers): Allocate some slop after `registers'
4590 to prevent stray accesses from trashing the next variable.
4592 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
4593 on the sun-3, by changing the #ifdef from `sun3' (which is not
4594 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
4595 vars, which happened to follow `registers' in the executable.
4597 * readline/history.c (history_search): Heed gcc-2's advice
4598 and parenthesize && inside ||).
4600 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
4601 tm-29k.c: Insert FSF copyright headers.
4603 * remote-eb.c: Better comments.
4605 * Makefile.dist: Update to 3.91.6.
4606 * TODO: note PREPARE_TO_STORE problem.
4608 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
4610 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
4612 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
4614 * infrun.c (wait_for_inferior, at end): Don't set up
4615 prev_* if the inferior no longer exists.
4617 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
4618 CANNOT_EXECUTE_STACK.
4619 valops.c (call_function): Use it.
4621 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
4623 * inferior.h (PC_IN_CALL_DUMMY): New macro.
4624 infrun.c (wait_for_inferior, 2 places): Use it.
4626 * values.c (value_being_returned): Only use
4627 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
4629 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
4630 right thing for remote-eb.c.
4632 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
4633 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
4635 * blockframe.c: Put get_frame_saved_regs inside #if !defined
4636 (FRAME_FIND_SAVED_REGS).
4638 * findvar.c ({fetch,store}_registers): Check for
4639 REMOTE_{FETCH_STORE}_REGISTER macro.
4641 * findvar.c (get_saved_register): Add argument lval and
4642 change meaning of argument addr.
4643 findvar.c: Change calls to get_saved_register to reflect
4644 new calling convention.
4645 valops.c (value_assign): Use get_saved_register instead of
4646 find_saved_register.
4648 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
4650 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
4651 an (uninitialized) pointer to one. Use "&" when passing it
4654 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
4656 * coffread.c (getfilename): Use DGUX x_offset and x_name if
4659 * coffread.c (symbol_file_command): Put semicolon after
4661 Put safe_to_init_tdesc_context in #if defined (TDESC).
4662 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
4663 coffread.c: #include <sys/stat.h>.
4664 (read_coff_symtab): Typo: in_source_files -> in_source_file.
4665 Add missing ')' in check for "lc%" and friends. Remove
4667 Declare read_one_sym() at top of file.
4668 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
4669 MC68WRMAGIC can have the same value without causing a duplicate
4672 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
4674 * Allow a Makefile to be built without building the
4675 tm and xm file links that screw up builds in subdirectories.
4676 This is done with `config.gdb none', then you can do things
4677 like `make gdb.tar.Z'.
4678 * tconfig/none: Config file for no target system
4679 * xconfig/none: Config file for no host system
4680 * config.gdb: If no TM or XM files are called out by the
4681 host or target file, don't make links for them.
4683 * cplus-dem.c: Add documentation.
4685 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
4686 simple error, so the user's gdb doesn't crash due to some object
4687 file problem (e.g. somebody is rebuilding the file out from under
4690 * printcmd.c (print_address_symbolic): demangle the symbol.
4692 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
4693 Motorola copyrights in it. Make "make gdb.tar.Z" work.
4694 (alldeps.mak): sort and uniq all results from this; duplicates
4695 hose gdb.tar.Z link building. Remove RCS files from
4696 tconfig and xconfig. Add config files for sun386. Add
4697 a few odd files to OTHERS and HFILES.
4699 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
4701 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
4702 Roll version number to 3.91.5. Make lint work in bindir.
4704 * README: Document cross-debugging and new file structure.
4706 * blockframe.c: Lint. Include "value.h" to declare read_register.
4707 (find_pc_partial_function): remove duplicate line.
4709 * command.h: Lint. Declare error_no_arg and dont_repeat.
4711 * tm-news.h: Remove inadvertently duplicated stuff.
4713 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
4714 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
4716 * config.gdb: Allow `config.gdb host target' form. Clean
4717 up previous change that printed bogus messages when you just said
4720 * core.c: #include "command.h" for lint.
4723 * main.c: Remove some casts of enums. Lint.
4730 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
4732 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
4733 read it from memory. This will allow us to save ptrace calls
4734 eventually. Changed caller single_step too.
4736 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
4737 that we aren't going to use, saving many ptrace calls, especially
4738 when watchpointing or single stepping. Use some #define's for
4740 (store_inferior_registers): Ditto.
4741 (core_file_command): Use some #define's for constants.
4743 * tm-sparc.h: Add #define's for some register numbers, so we
4744 can eliminate the use of random constants in sparc-xdep.c.
4746 * stack.c (frame_command, print_frame_info, up_command,
4747 down_command) Remove frame_changed, since it
4748 causes a bug and doesn't seem to do anything useful. In some
4749 places it was used as a flag, in others as a stack level (?).
4751 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
4752 default is to use the portable (vprintf) version rather than the
4754 * xm-news.h (MISSING_VPRINTF): Add.
4756 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
4758 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
4760 * Remove stuff that forces -Bstatic linking of gdb, and warnings
4761 about linking debugged programs -Bstatic in the sun?os4 config
4762 files in tconfig and xconfig subdirectories.
4764 * main.c (main): Remove unreached exit(0) now that we exit
4767 * Create TODO file for online bug list. There are too many
4768 "little" bugs to keep track of on paper.
4770 * Change Projects file to refer to bug-gdb@cygnus.com
4771 rather than kingdon@ai.
4773 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
4775 * Makefile.dist (VERSION): 3.91.4 now.
4777 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
4778 (condense_misc_bunches): Add sanity check that misc_count is
4779 the same as the number of symbols in the bunch.
4781 * coffread.c: rename init_misc_bunches. Pass an argument
4782 to condense_misc_bunches (a zero).
4784 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
4785 every time we are called; don't rely on our caller to do it.
4786 (add_file): Remove call to init_misc_bunches.
4788 * mipsread.c: Only warn, don't error, if unknown symbol types.
4789 This keeps an old gdb from falling on its face if it sees newly
4790 extended symbol info. Rename init_misc_bunches.
4792 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
4794 * Merge in changes from Per Bothner for DECstations and other
4795 MIPS stuff. The rest is Bothner speaking:
4797 The next message is a merger of Alessando Forin's mips port with
4798 mine. I've tried to use my good if biased judgment to get
4799 the best of both. It *does* need testing.
4801 Some of the changes are general, *not* mips-specific.
4804 Didn't believe in little-endian bit order.
4805 There are still inconsistencies about whether flags
4806 like BITS_BIG_ENDIAN are integer (#if ...) or
4807 boolean (#ifdef ...). I tried to paper over them.
4809 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
4810 Moved some misc_function code that was common to
4811 {dbx,coff,mips}read.c to symtab.c.
4812 In the process, I think I cleaned things up a bit.
4813 At the same time, moved obsavestring and obconcat to symtab.c.
4816 Removed obsolete condense_addl_misc_bunches (use
4817 condense_misc_bunches(1) instead).
4820 Needed to include <sys/dir>, at least on DECstations.
4822 valops.c, mips-tdep.c, tm-mips.h:
4823 Added PUSH_ARGUMENTS macro to support funny argument-pushing
4824 conventions (when STACK_ALIGN is insufficient).
4825 Needed on mips, where doubles need 8-byte alignment,
4826 but ints only need 4.
4829 Removed cruft that was not being used.
4830 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
4833 Print $ before register-names (I think that makes things a little
4835 Never print two instructions, even if one delays.
4836 Removed hex-disassemble set_cmd. (This is not mips-specific,
4837 so I think the argument is whether it is generally worthwhile or not.
4838 I'm inclined to think not, given how easy it is to
4839 convert between radixes in gdb.)
4842 This is basically Alessando's code.
4843 It doesn't use obstacks; I changed it to use obstacks
4844 in a few minor places where using malloc causes a
4845 memory leak. (Probably, more places could/should be changed.)
4846 I added record_misc_function where it was missing.
4847 In symbol_file_command and add_file_command, I tried
4848 to make the code consistent with more recent versions.
4849 Minor sylistic changes in parse_procedure.
4850 Make a .gdbinfo. psuedo-symbol point back to the real
4851 procedure symbol (using the isym field).
4854 This is basically from my port, but with a lot of details
4855 and a number of routines merged in from Alessando's version.
4856 I basically used my code "raw" backtrace (use heuristics
4857 from the actual code, rather than symbol table info) - though
4858 the idea is Alessandro's. I feel my code is a little cleaner
4859 here, particularly in being a little more flexible, such as being
4860 able to handle gcc-produced code (which it now can).
4861 It also doesn't do frame caching (which is not useful
4862 more recent gdb versions).
4863 I also used my code for push_/pop_dummy, more or less.
4864 I tried to incorporate AF's code for testing sigtramp
4865 while backtracing; I probably got it wrong.
4866 Added mips_print_register, which tries to scrunch as much
4867 information as possible on a screen...
4868 Removed the skip-prologue set_cmd. As with hex-disassemble (see
4869 under mips-pinsn.c), I don't see anything mips-specific here,
4870 and I don't see it being all that useful anyway.
4873 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
4874 Use more register names (rather than hard-cases numbers).
4876 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
4878 * Hack up 3.90.11 changes:
4880 * Makefile.dist (depend): parameterize $(GCC).
4881 Add solib.c and solib.o.
4882 (readline): Fix vpath for both absolute or relative SRCDIR.
4884 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
4885 Also, let the part I didn't understand at least compile so
4886 I can test the rest. FIXME.
4888 * dbxread.c: Fix thinko using strcmp.
4889 (init_psymbol_list): declare static.
4890 (partial_symbol_file_open): Comment cleanups better, avoid
4891 cleaning up the string table since the caller will do that.
4892 Move the stat for mod time into symbol_file_command, temporarily.
4893 (There should be a mod time for each symbol file, eventually,
4894 to control its rereading. FIXME.)
4896 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
4897 SunOS, which gives error for shared libs otherwise. (From
4898 Schaefer, probably FIXME needs work for portability.)
4900 * solib.c: Move #include "param.h" to work.
4901 Lowercase all the Uppercase Letters In the Messages.
4902 (find_solib): Clean up inferior_so_name for debug printouts.
4903 Allow no argument, to mean all shared libraries.
4905 * symmisc.c: include param.h to get CLEAR_SOLIB.
4907 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
4909 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
4910 to 3.90.11. ChangeLog entries below are from this.
4912 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)

4924 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
4926 * sparc-opcode.h Added single-operand version of rett.
4928 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4930 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
4931 Put parens around gcc_p in expansion.
4933 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
4935 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
4937 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4939 * Changes for Sun shared libraries:
4940 blockframe.c (find_pc_partial_function): If a non-text symbol
4941 is found, set *address = pc - FUNCTION_START_OFFSET.
4942 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
4943 Disable breakpoints instead of giving an error.
4944 source.c (select_source_symtab): Initialize cs_pst.
4945 symmisc.c: Call CLEAR_SOLIB if defined.
4946 symtab.h: Make text{low,high} CORE_ADDR not int.
4947 (psymtab): New field addr.
4949 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
4950 (record_misc_function): Give correct type for N_DATA symbols.
4951 (condense_misc_bunches): do "misc_function_count = j" regardless
4953 Take code which is shared between symbol_file_command and
4954 add_file_command and put it into partial_symbol_file_{open,read}.
4955 Split add_file_command into add_file_command and add_file.
4956 Make psymtab_to_symtab read in the string table if the file
4958 Two new parameters to read_dbx_symtab and start_psymtab.
4959 tm-sunos.h: New file.
4961 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4963 * infcmd.c: Change cont_command to continue_command and "cont"
4966 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4968 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
4970 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
4972 * values.c (USE_STRUCT_CONVENTION): Check for structures of
4973 size 1,2,4,8 rather than size < 8.
4975 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
4976 as necessary, not just once.
4978 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
4980 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4982 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
4984 * tm-news.h: Add CALL_DUMMY_*.
4986 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
4988 * config.gdb: In list_host, list_target, use ${i}, not $i.
4990 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4992 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
4994 * sparc-opcode.h: Change all store floating-point state register
4995 instructions to have the right match & lose fields.
4997 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4999 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
5001 config.gdb: If srcdir != ., create readline directory and
5002 copy a makefile into it.
5004 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
5005 consistency with POSIX.
5007 * breakpoint.c (bpstat_stop_status): Disable watchpoint
5008 when we exit its exp_valid_block.
5010 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
5012 * Makefile.dist: Bump version to 3.91.3.
5014 * Clean up handling of breakpoint commands (somewhat).
5015 Prompted by Tiemann bug report "cont 10" doesn't work any more.
5017 inferior.h: Add breakpoint_proceeded to inferior status struct
5018 and globals; save it and restore it.
5019 (clear_breakpoint_commands): Cleanup, remove old #define.
5021 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
5022 (save_inferior_status, restore_inferior_status): handle it also.
5023 (proceed): Remove earlier code that set breakpoint_proceeded.
5024 It is now set only in clear_proceed_status.
5025 (clear_proceed_status): Cleanup, use bpstat_clear rather
5026 than clear_breakpoint_commands. No callers need the stop_bpstat
5027 between clear_proceed_status and proceed.
5029 infcmd.c: Add breakpoint_proceeded definition and comment.
5030 (cont_command, jump_command, signal_command): Move call to
5031 clear_proceed_status right next to call to proceed.
5033 breakpoint.c (bpstat_do_actions): Avoid clobbering our
5034 caller's argument while running down the chain of breakpoints.
5035 Use new variable "breakpoint_proceeded" to determine when
5036 a command that it executes moves the inferior past the
5038 (bpstat_clear): Handle NULL argument.
5039 (bpstat_clear_actions): Avoid useless call to
5040 breakpoint_auto_delete.
5041 (delete_breakpoint): Clean up bpstat's that are pointing to
5042 the deleted breakpoint from the stop_bpstat chain.
5043 (breakpoint_auto_delete): Simplify.
5045 * Clean up handling of EOF, error on stdin, etc. This was
5046 prompted by a network problem that caused gdb to go into an
5047 infinite loop filling up its malloc'd memory.
5049 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
5050 not clear_breakpoints_commands, which is now gone.
5051 (main): If command_loop returns (e.g. from EOF on stdin), do
5052 a quit_command (looping back to command_loop if quit_command
5053 doesn't really quit).
5054 (command_loop): check result from command_line_input and
5055 exit if it returns NULL, rather than passing the NULL to
5057 (gdb_readline): Free malloc'd result space before returning
5060 * utils.c (query): Handle C-d to mean "yes", just as if the
5061 input was not a terminal. Also avoid infinite loop if EOF
5062 occurs in mid-input-line before newline. This allows
5063 query to be used at EOF on stdin with reasonable results.
5065 * infrun.c (proceed): Set breakpoint_proceeded.
5067 * values.c (value_as_long): Avoid infinite recursion for enums.
5068 (_initialize_values): Fix typo in help msg (kingdon).
5070 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
5071 RL_LIB for linking. This allows -lreadline for linking
5072 and nothing for dependencies, once readline is a real library.
5074 * config.gdb: Jim Kingdon: give useful error message if the
5075 host or target type is not recognized.
5077 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
5078 it just defines it. Dumb, but deal with it.
5080 * Jim Kingdon suggests:
5081 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
5083 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
5085 * Makefile.dist (VERSION): Bump version # to 3.91.2.
5087 * Clean up Bothner's changes.
5089 * blockframe.c (clear_pc_function_cache): New function.
5090 * blockframe.c: remake cache_pc_function_* static.
5091 * dbxread.c (symbol_file_command): remove references to
5092 cache_pc_function_* variables.
5093 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
5094 * printcmd.c: Avoid kludging a global variable (addressprint)
5095 to avoid printing the address of a string twice. Instead,
5096 pass the format letter 's' down low enough that it can be seen
5097 to avoid this problem.
5098 (print_formatted): Pass format arg to value_print.
5099 (restore_addressprint): Remove function.
5100 (do_examine): Avoid hacking addressprint, cleanups and such.
5101 (print_frame_args): Add a comment to a Bothner change.
5102 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
5103 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
5104 to wipe out the values cached in blockframe.c.
5105 * symtab.c (find_method): Add comment saying how big you must
5106 allocate to be "big enough". Per being terse again.
5107 * valprint.c (val_print): Handle format letter "s" to print
5108 strings without addresses. Add comment to vtbl printing code
5109 which casts with wild abandon. Rearrange reference-printing
5111 @0xaddr: value (print w/addressprint)
5112 value (print w/~addressprint)
5113 @0xaddr (parameter lists w/addressprint)
5114 or nothing (parameter lists w/o addressprint)
5116 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
5118 * Merge more changes from Per Bothner:
5120 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
5121 annoying) that I tried to improve it. Here are my suggestions.
5123 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
5126 Do automatic de-reference when taking the address of a reference.
5128 Don't deref_ref when printing parameter lists.
5130 More attempts at treating refernences properly.
5132 In val_print, if deref_ref==0, don't print dangling " = ".
5134 Add COERCE_REF macro, which de-references an REF.
5136 * Merge changes from Per Bothner:
5138 * Fixed (Sony news)-specific configuration problems.
5139 * Fixed other problems with using vanilla pcc and libc (enum problems;
5140 assumption that vsprintf exists).
5141 * Some major speed-ups (finc_pc_partial_function now caches a match;
5142 parsing avoids duplicate symbol_lookup calls).
5143 * Changed handling of baseclasses (no longer use baseclasses field
5144 of struct type, use the first n_baseclasses fields instead).
5145 * Various minor changes/fixes, most C++-related.
5148 Cache the most previous match from find_pc_partial_function.
5149 (Save both low and high ends of matching function's pc range.)
5150 This speeds up the loop of infrun.c:wait_for_inferior quite
5151 a bit, and makes step/next commands much zippier.
5153 Added an enum->int cast (otherwise, some compilers barf).
5155 No longer set baseclass offset to 0, since multiple
5156 inheritance now mostly works.
5157 Added a number of casts, to shut up compiler warnings
5158 (after stabs where made enums, not ints).
5159 When discarding a symbol table (in symbol_file_command),
5160 must clear the cache introduced in blockframe.c.
5161 Don't convert $vtbl_ptr_type to vtbl any more.
5162 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
5163 Mask off sign bit emitted by g++ for virtual table offset.
5164 Set voffset to -1 (not 1) for static member functions.
5166 Changed parsing/lexing of names to avoid doing symbol lookup twice
5167 (once when lexing to determine symbol class, once for real).
5168 Now only call symbol_lookup once. Fields of 'this' win especially big.
5170 Subpress printing addr twice in the case of 'x/s addr'.
5172 lookup_basetype_type is no longer used.
5173 Add find_methods as recursive helper function to decode_line_1.
5174 This allows multiple inheritance to work.
5175 Also, once one or more matches has been found, do not look in
5176 base-classes. (Baseclass methods would be overridden, anyway.)
5178 Removed baseclasses array in struct type.
5179 Instead of using baseclasses[i], use fields[i-1].
5180 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
5181 Changed sign convention of voffset (previous was inconsistent).
5183 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
5185 Used to assume existence of vsprintf. Re-written to not need it
5186 if HAVE_VPRINTF is undefined.
5188 typecmp was too pessimistic. Made it less so.
5190 Don't print space after address.
5191 If vtable points to a misc symbol (with 0 offset), print it,
5192 since that indicates the actual class of the object.
5193 Changed ype_print_derivation_info to use new inheritance
5194 scheme (without baseclasses vector).
5196 In value_primitive_field, fixed some bugs left over from previous set of fixes.
5197 Also, changes needed because TYPE_BASECLASSES were removed.
5199 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
5201 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
5204 If there is no path set, and the symbols don't indicate what directory
5205 a file was compiled in, look in the current directory. But either
5206 a path or a known compilation directory will prevent this.
5209 Three independent bug fixes:
5210 * Remove the #if 0 block that breaks some stuff.
5211 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
5212 adapt gdb to either SunOS 4.0.* or 4.1.
5213 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
5216 Instantiate the class T when looking for methods in it. (Tiemann@sun)
5219 (type_print) Demangle the name being printed.
5220 (type_print_base) Handle botched demangling without coredump (tiemann).
5223 (check_stub_method): Document routine.
5224 (tiemann) fix bug for no-arg functions
5225 Avoid clobbering beyond end of malloc'd storage.
5226 Terminate the argument list properly.
5228 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
5230 * Changes merged by John Gilmore:
5233 In breakpoint_1, use new print_address_symbolic instead
5234 of find_pc_partial_function. (This forces use of assembler-level
5235 addresses, and avoids misleading non-mangled source-level names.)
5237 Generalize ansi argument such that -1 means skip arglist totally.
5238 Removed global variable print_ansi_qualifiers (which made
5239 code non-reentrant), in favor of extra explicit arguments
5240 to internal routines.
5242 Add new helper function print_address_symbolic.
5243 Use find_pc_misc_function instead of find_pc_partial_function
5244 (since we want assembler-level symbols here).
5246 Print unknown function as just "f (...)", not "f (...) (...)".
5247 Use new fputs_demangled explicitly.
5249 Fixed a typing violation (problem: value.h cannot be imported
5250 without renaming many variable in this file).
5251 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
5252 decode_line_1: Moved forward some never-reached code.
5253 Made decode_line_2 skip function prologues correctly.
5255 fputs_filtered should not demangle by default.
5256 Add new fputs_demangled to demangle on demand..
5258 Change value_struct_elt to use value_primitive_field (using recursive
5259 utility function search_struct_field). This allows foo.bar to work
5260 for multiple inheritance (so far only for data fields).
5261 Change check_field in the same way (recursive helper function
5262 to support multiple inheritance).
5263 (Note: there are more of these problems that I haven't fixed.
5264 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
5265 value_of_this: 'this' symbol name is now just "this", note "$this".
5267 Don't print static members.
5268 Avoid printing "members of <type>" if there are none.
5269 Simplified type_print_derivation_info by merging duplicate code.
5270 Remove useless blank lines in type_print_base (ptype command).
5272 Added declaration of new routine value_primitive_field.
5274 Added value_primitive_field which is generalized version of
5275 value_field that can handle multiple inheritance (non-zero offsets etc).
5276 Re-implemented value_field to call value_primitive_field.
5278 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
5280 * infcmd.c -- insert else to avoid 'delete env' coredump when you
5281 delete the whole environment. Karl Berry reported the bug.
5282 * source.c - fix openp to avoid //'s in filenames, which
5283 trigger an Emacs bug causing it to not be able to find files
5284 when running gdb in a window.
5285 * dbxread.c - zap the #if 0 that botches the add-file code.
5286 It seems to work a lot better without all the code commented out.
5288 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
5290 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
5293 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
5295 * Makefile - added a ${CFLAGS} to a couple of entries,
5296 added remote-sa.sparc.c
5297 * added remote.sa-sparc.c, a modification of remote.c
5298 which conducts a dialog directly with the SparcStation prom.
5299 * breakpoint.c, infrun.c, sparcdep.c added
5300 remote_insert_breakpoint(), and remote_remove_breakpoint()
5301 to breakpoint.c instead of directly writing breakpoint instructions.
5302 * sparcdep.c on remote_debugging,there is no need
5303 to remove signle step breakpoint instructions.
5304 * main.c added "-epoch" flag and "int epoch_interface" to main.c
5306 * printcmd.c - epoch interface sends lisp expressions to open up
5307 epoch windows on inspection.
5308 * valprint.c - added arrayprint, and addressprint and made adding
5309 format controls easier
5310 * wait.h added a couple of undef's because we were getting
5311 complaints about WSTOPSIG and WTERMSIG begin redefined.
5314 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
5316 * symtab.c (decode_line_1): Add support for handling method stubs
5317 in the type information.
5319 Tue Jul 3 09:39:18 1990 Michael Tiemann (tiemann at masham)
5321 * values.c (baseclass_addr): Run loop from INDEX+1 to
5322 N_BASECLASSES; otherwise, we can still get into a loop.
5323 @@ This should be restructured to use a cleaner search strategy.
5325 Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
5327 * dbxread.c (define_symbol,read_type): Grok GNU C++'s new
5328 abbreviation "Tt" for tags which have the same name as their
5331 Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham)
5333 * symtab.c (list_symbols): add ability to set breakpoints on all
5334 the functions which match a particular regular expression.
5336 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
5338 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
5339 should print ANSI qualifiers (such as `const' and `volatile').
5340 All callers changed to call with ANSI == 1, except from
5341 `check_method_stub', which uses old-style syntax.
5343 * symseg.h (struct fn_field): Remove unneccessary `args' field.
5344 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
5346 * values.c (check_stub_method): New function.
5348 * cplus-dem.c (do_type): Handle "long long" (encoded as 'x').
5350 * dbxread.c (read_type): Handle new GNU C++ method type stubs.
5351 * valprint (type_print_base): Ditto.
5353 * symtab.c (gdb_mangle_typename): New function.
5355 Tue Jun 5 00:18:43 1990 Michael Tiemann (tiemann at gzilla)
5357 * breakpoint.c (catch_command): New function. Provides a
5358 mechanism to set breakpoints based on catch clauses.
5359 (disable_catch): Similar, but disables breakpoints on catch
5361 (delete_catch): Similar, but deleted breakpoints on catch clauses.
5363 Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla)
5365 * blockframe.c (blockvector_for_pc): New function.
5366 * blockframe.c (block_for_pc): Changed to call
5367 `blockvector_for_pc' and get the block itself.
5369 * stack.c (catch_info): New function. Prints info about
5370 exceptions which can be caught in the current frame.
5371 * stack.c (print_frame_label_vars): New function. Similar to
5372 `print_frame_local_vars'.
5373 * stack.c (print_block_frame_labels): Prints out labels that are
5374 defined in this frame. These labels are exceptions that can be
5377 * dbxread.c: Updated to handle N_CATCH symtab types.
5379 Thu May 3 22:10:00 1990 Michael Tiemann (tiemann at teacake)
5381 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
5382 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
5383 when printing the type.
5385 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)
5387 * valprint.c (val_print): Use `baseclass_addr' to access the
5388 baseclasses pointed to via the derived class object at VALADDR.
5390 * values.c (baseclass_addr): New function. Casts derived pointers
5391 to baseclass pointers taking virtual baseclasses and multiple
5392 inheritance into account.
5394 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5398 Fri May 4 12:12:55 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5400 * breakpoint.c (watch_command, bpstat_stop_status): Deal with
5401 exp_valid_block field correctly.
5403 * infrun.c (wait_for_inferior): When checking "don't even think
5404 about breakpoints" if stop_signal == SIGTRAP && trap_expected,
5405 also check step_resume_breakpoint.
5406 Insert breakpoints and continue (not step) if
5407 step_resume_break_address != NULL, even if another_trap.
5408 If trap_expected and we enter sigtramp, then set up a
5410 If trap_expected is set when we hit the step_resume_break,
5412 When calling resume and trap_expected says tell resume to step
5413 (2 places), also check step_resume_break_address.
5415 * infrun.c (wait_for_inferior): Don't set
5416 prev_{pc,sp,func_{start,name}} before calling wait ().
5417 Do set them after exiting loop.
5418 Move their declarations outside functions.
5419 (start_inferior): Initialize them.
5421 Thu May 3 00:15:11 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5423 * infrun.c (wait_for_inferior, after check for trap_expected > 1):
5424 Restore old code which distinguishes between trap_expected and
5425 running_in_shell, just make the latter take any non-TRAP signal,
5428 * values.c (allocate_value): Zero VALUE_OPTIMIZED_OUT flag.
5430 * Makefile.dist (pinsn.o): Use PINSN_CC to compile.
5431 xconfig/3b1 (CC,PINSN_CC): Define.
5433 * xconfig/altos, altos-dep.c: Rename altos-dep.c to altos-xdep.c.

5438 infrun.c (wait_for_inferior) [SHIFT_INST_REGS]: New code.
5440 * param.h, tm-88k.h: Define ADDR_BITS_*.
5441 infcmd.c (jump_command, read_pc), infrun.c (wait_for_inferior),
5442 printcmd.c (do_one_display): Use them.
5444 * utils.c: Split #ifdef USG into a USG_UTILS and a QUEUE_MISSING.
5445 xm-88k.h: Define USG_UTILS.
5447 Wed May 2 00:05:33 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5449 * printcmd.c (printf_command) [__INT_VARARGS_H]: New code.
5450 (printf_command): Add from_tty parameter.
5452 * valprint.c (value_print): Check VALUE_OPTIMIZED_OUT flag.
5454 * value.h: Add optimized_out field and change lazy field to
5455 char. Add macro VALUE_OPTIMIZED_OUT.
5457 * i386-pinsn.c: Change from Eirik Fuller to write to stream directly
5458 instead of stuffing things in buffers (oappend, etc).
5460 * breakpoint.c (bpstat_do_actions): If *BSP is set to NULL by
5461 execute_command, exit both loops.
5463 * Makefile.dist: Don't set TARGET_ARCH. Add .c.o rule.
5465 Tue May 1 17:07:23 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5467 * Makefile.dist (RAPP_OBS, rapp),
5468 rgdb.c, rserial.c, rudp.c, serial.c, udp.c, xdep.h,
5470 m68k-xdep.c, coredep.c: Wrap in #if !defined (RDB).
5472 * valops.c (value_struct_elt), values.c (value_static_field):
5473 Change error messages to remove references to `info methods'.
5475 Tue Apr 24 10:25:10 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5478 infrun.c (start_inferior): Add START_INFERIOR_HOOK.
5479 infcmd.c [SHIFT_INST_REGS]: New code.
5480 findvar.c (read_relative_register_raw_bytes): Return a value.
5481 infcmd.c (do_registers_info): Check value from
