1 Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
3 * Makefile.in (HFILES): Add minimon.h.
4 (VERSION): Roll version number to 4.0.95.
5 (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
6 New rules for building distributions. Normal distribution
7 is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
8 one level up from here; it calls make-proto-gdb.dir to build a
9 directory `proto-gdb' which is an image of the release. The old
10 `gdb.tar.Z' rule still works too.
11 * config.sub, configure: Roll in latest from ..
13 Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
15 * doc/gdbint.texinfo: Reorder contents; reorganize new-host,
16 new-target, and new-config chapters; fix minor typos; come closer
17 to usual GNU markup conventions for @file @samp @code @var.
19 Thu Sep 19 17:04:12 1991 Per Bothner (bothner at cygnus.com)
21 Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
22 * mipsread.c (parse_partial_symbols): Enter the name of all
23 structs/unions... into the psymtab so we can access them if the
24 symtab is not read in.
25 * mips-tdep.c: Remove some unneded (?) #includes.
26 * xconfig/dec3100: Add HAVE_STRSTR.
28 Thu Sep 19 15:14:23 1991 John Gilmore (gnu at cygnus.com)
30 * Makefile.in: Circumvent Sun Make bug on *-exp.tab.o.
31 * c-exp.y, m2-exp.y: Lint.
32 * m2-exp.y: Avoid using yytname[] which is a Bison-ism.

138 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
140 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
141 entries are enclosed herein:
143 Mon Jun 3 17:05:45 EDT 1991
145 m2-exp.y Created. Tested outside of GDB for a few days. Proper
146 operators were added, C specific operators and tokens
147 removed. yylex() revamped to some extent. Still things
148 missing from the grammar, such as sets.
149 Tested for two weeks in GDB v3.5.
151 Tue Jun 11 17:23:48 EDT 1991
153 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
154 so they are built-in. Sort of a hack.
156 Fri Jun 14 12:53:51 EDT 1991
158 m2-exp.y Added range checking for numeric constants. Any numeric
159 constant is assumed to be of builtin type INTEGER unless:
160 (1) it is octal or hexadecimal, in which case it is a
161 CARDINAL; (2) it is too big to fit into an INTEGER, in
162 which case it is a CARDINAL.
163 eval.c Added simple range checking for +, -, and * on integers.
164 Doesn't work very well for *, since 6 * 1,000,000,000 =
165 1,705,032,704, which fails the simple test of result >=
166 first_operand, no matter in what order the operands are.
168 Tue Jun 18 14:11:30 EDT 1991
170 Broke the parser into parts, one containing the C grammar and the other
171 containing code to be shared by all of the grammars.
173 The following files no longer exist:
178 The following files were added:
180 c-exp.y (The C grammar)
181 m2-exp.y (The Modula-2 grammar)
182 parser-code.c (Code that is shared by the above grammar)
186 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
187 now necessary to use the Bison compiler compiler, since it
188 will generate function/variable prefixes other than yy.
190 Tue Jun 18 16:47:49 EDT 1991
192 symtab.[ch] Added the external variable working_lang, than holds the
193 value of the current working language.
194 Added the ennumerated type language_mode, with the values
195 language_auto and language_manual, the former meaning that
196 GDB sets working_lang as needed, and the latter meaning
197 that the value of working_lang is totally under user
199 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
200 REAL, BOOLEAN and CHAR. Also added the type codes
201 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
202 utils.c Added set_language_command and show_language_command to
203 implement the GDB support commands "set language" and
205 expression.h A number of identifiers were added to the type exp_opcode
206 to facilitate Modula-2 builtin functions, integer
207 division, and array indexing.
209 Wed Jun 19 13:25:58 EDT 1991
211 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
212 if the language specified by working_lang requires the use
213 of strict typing of expressions. Eventually, even this
214 will be able to be changed by the user.
215 Added the macro RANGE_CHECK, which evaluates to non-zero
216 if the language specified by working_lang requires the
217 checking of a value against the domain of its type.
218 Eventually, even this will be able to be changed by the
220 language.[ch] Predicates involving types (simple_type, ordered_type,
221 same_type, integral_type, numeric_type, character_type,
222 boolean_type, float_type) are added. These predicates are
223 based on the current value of working_lang, and are handy
226 Wed Jun 19 15:39:34 EDT 1991
228 eval.c Added the function type_array_rank which computes the rank
230 valarith.c Added the funtion value_bool, which when given a integer
231 value.h value (ie. struct value *) as an argument, it returns a
232 boolean value (ie. struct value *) true if that integer
233 is non-zero, and a boolean value false otherwise.
234 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
235 will print out properly.
237 Wed Jun 19 16:36:34 EDT 1991
239 valops.c Added the function value_capitalize, which returns it
240 value.h argument capitalized if its argument is a lowercase
241 letter, or the argument unchanged if its argument is not a
243 valarith.c Added the function range_check_p, which returns non-zero
244 value.h if its value argument is between the integral bounds upper
246 Added the function range_check_enum_p, which makes sure
247 that its value argument is a valid member of the domain of
249 Added the function range_check_range_p, which makes sure
250 its value argument lies between the upper and lower bounds
251 of its type argument, which must be a ranged type.
252 Added the function check_array_index, which range and type
253 checks an index of an array.
254 Added the function value_multi_subscript, which computes
255 array[idx1,idx2...idxN], given a value array and an array
256 of values representing indicies.
257 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
258 unpack_long to work with TYPE_CODE_BOOL and
261 Wed Jun 19 18:04:08 EDT 1991
263 symtab.c Stored pervasive types in a structure and make
264 lookup_pervasive_type() a lookup function that was based
265 on working_lang. If lookup_pervasive_type() returned
266 non-zero, then that value was returned (a fix, since
267 before it simply wouldn't return the pervasive type.)
268 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
269 non-zero if the language specified by working_lang means
270 "conversion" when it says "cast".
271 valops.c Added the function value_real_cast(), which performs a
272 value.h *cast*, not a *conversion*, which is what value_cast()
273 does when it can. In particular,
274 value_cast(<float_type>,4) = 4.0, while
275 value_real_cast(<float_type>,4) = some mess.
276 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
277 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
278 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
279 and MIN on integral types. *NOTE*: These are currently
280 hardcoded to work only if there are 8 bits per storage
282 eval.c Made logical functions call value_bool to return a
283 properly typed boolean value, based on working_lang.
285 Thu Jun 20 11:55:27 EDT 1991
287 valprint.c Types now print out in a Modula-2 fashion. This works for
288 the cases when the type is printed out step-by-step, that
289 is, it doesn't work when the name of a structured type
290 (which includes the keyword "struct", etc.) is simply
292 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
293 since type specifications in C and Modula-2 are very
294 different. The C printing of a type is very recursive,
295 whereas in Modula-2 it is generally very simple. C has
296 type prefixes and suffixes, which have no real analogue in
297 Modula-2. Maybe type_print() should call a language
298 specific type printer. This is also advantageous if we
299 compile GDB to exclude some of the languages. We'll just
300 leave those functions out.
302 Thu Jun 20 16:57:10 EDT 1991
304 dbxread.c When reading the complete symbol table in (via
305 psymtab_to_symtab()), the number and types of function
306 arguments are added to a function type. define_symbol()
307 calls add_param_to_type() to accomplish this.
308 Assumption: when we come across a function definition
309 (N_FUN symbol with an 'f' or 'F' in the name), its
310 arguments will appear before another function definition.
311 When a function is found, a pointer to its type is placed
312 in the global in_function_type. Changes that
313 add_param_to_type() makes are to this global.
314 valprint.c The type of a function now includes (for Modula-2) the
315 types of its parameters.
316 eval.c Type checking and a check for the proper number of
317 arguments is now done for function calls. Not sure of the
318 impact this has on C++ member function yet.
320 Thu Jun 20 19:58:48 EDT 1991
322 valprint.c Rewrote the type printer. Broke it into two language
323 specific parts, adding the functions type_print_m2() and
325 An unfortunate consequence is this: if you debugging a C
326 program in Modula-2 mode (why?), info types does not work
327 well with regular expressions, since the types are printed
328 out in Modula-2 terminology, but stored in C terminology.
329 language.[ch] Added the functions new_type_last(), type_keyword(), and
330 type_sep() to aid in the printing of typedefs.
331 symtab.c Made the printing of typedefs as language independent as
332 possible through calls to new_type_last(), type_keyword(),
335 Fri Jun 21 11:50:26 EDT 1991
337 dbxread.c Check all incoming ennumerated types. If it looks like
338 Modula-2's BOOLEAN type, then change the type_code of the
339 type to TYPE_CODE_BOOL so we can process it as a boolean
341 valprint.c Replaced some of the 0x%x with calls to sprintf and
342 hexformat() in val_print().
343 language.[ch] Added the function hex_to_string(), which converts its
344 integral argument to a hexadecimal number (format is
345 language based) and returns the result as a string.
347 Mon Jun 24 12:25:07 EDT 1991
349 valprint.c Some functions call type_print_1() directly, instead of
350 value.h using type_print(), so they can specify where (column) to
351 print things. Since type_print() takes care of language
352 dependence, that needs to be called first. Added a
353 parameter depth to type_print() (so it is now like
354 type_print_1). Changed type_print to type_print_at, and
355 made type_print a macro that passes a depth argument of
357 symmisc.c Changed all calls to type_print_1 to calls to
359 Makefile.dist Made it possible to build GDB for a specific set of
360 depend languages. Do this by passing a definition for the macro
361 LANGS to make. LANGS should be a string containing a
362 space-separated list of language names (ie. LANGS="c m2").
363 The default is to build all languages. Note that grammar
364 files must follow the naming convention of <lang>-exp.y.
365 gdb.lang This holds the current value of the LANGS macro. It is
366 examined every time make is called, and is updated if
368 eval.c Added #ifdef _LANG_<lang> to these files.
369 expread.c Still need to add them to dbxread.c and coffread.c.
377 Mon Jun 24 16:33:11 EDT 1991
379 language.[ch] Added the functions hexformat_pre() and
380 hex_to_string_pre(), which take a prefix argument to
381 include in the format string. Thus, hexformat_pre("08") will
382 return "0x08x" (if the working language is language_c).
383 Made hexformat() and hex_to_string() calls to the above
384 with "" as the prefix argument.
386 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
387 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
388 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
389 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
390 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
391 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
392 valprint.c, vax-pinsn.c
394 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
395 calls to hexformat() and hex_to_string(). Format strings without
396 the leading "0x" were ignored.
398 depend Updated to take the above into account.
401 Tue Jun 25 15:27:18 EDT 1991
403 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
404 and type_check_t to keep track of the current state of
405 range and type checking.
406 main.c Added the variables range_mode, range_check, type_mode,
407 and type_check to record the current state of range and
408 type checking. Added initialization code to main().
409 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
413 Tue Jun 25 17:57:08 EDT 1991
415 dbxread.c process_one_symbol() updates the variable (enum language)
416 source_lang based on the extension of the filename
417 contained in the N_SO sybmol that started this symtab.
418 When end_symtab() is called, the value of source_lang is
419 put into the language field.
420 stack.c select_frame() sets working_lang (and possibly type_check
421 and range_check) to the language field of the symtab
422 associated with the frame that is selected if working_mode
423 is language_auto. If working_mode is language_manual, a
424 warning is printed and working_lang is not set.
425 language.c Added the function set_type_range(), which sets the value of
426 type_check and range_check (if their modes call for
427 automatic setting) based on the current value of
428 working_lang. A non-zero argument will cause the current
429 settings to be output.
432 Wed Jun 26 14:51:40 EDT 1991
434 eval.c Added range checks on assignment.
435 m2-exp.y Added the grammar for sets to the language. Currently,
436 these do not do anything except print an error message.
438 Wed Jun 26 17:01:04 EDT 1991
440 m2-exp.y Added the ability for parse_number() to parse negative
441 numbers. A global flag is set upon encountering a unary
442 minus. This was done to make, for example, 1 parse as a
443 CARDINAL, and not as an integer, per Wirth's examples in
444 Programming in Modula-2 ed.4.
445 valprint.c Added support for "set radix 2" by then setting
446 output_format to 't'.
447 eval.c Implemented range checking on subrange types. Added calls
448 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
449 Implemented MIN and MAX for ennumerated types. The
450 minimum value of an ennumerated type is defined by Wirth
451 as the first identifier, and the maximum as the last.
452 m2-exp.y Made octal numbers ending with "B" be characters and those
453 ending with "C" be numbers, per Wirth's book. (p. 34)
455 Thu Jun 27 14:11:52 EDT 1991
457 stack.c select_frame() now only sets working_lang, it does not
458 notify the user. If working_mode is language_manual, then
459 a warning is issued once.
460 main.c At the end of each call to execute_command(), working_lang
461 is checked against the local static (enum language)
462 current. If they differ and working_mode is
463 language_auto, the new settings of language, type and
464 range checking are printed out.
465 stack.c Modified frame_info() to include the language of the
466 current frame in the output of "info frame".
467 language.[ch] Added the function language_str() which returns the name
468 of the current language.
470 Fri Jun 28 15:33:14 EDT 1991
472 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
473 the language. INCL and DECL currently cause an error,
474 since sets are not implemented yet. INC and DEC are
475 implemented as PREINCREMENT/PREDECREMENT with one
476 argument, and as ASSIGN_MODIFY with two arguments.
477 eval.c Added type checking to the above cases.
478 value.h Added not_lval_constant to the lval_type ennumerated type.
479 not_lval_constant means that the value is a constant
480 value; that is 3 or 'a' or TRUE, not as in a constant
481 identifier. This is used to help coerce numbers such as 3
482 to either signed or unsigned numbers.
483 valops.c Added the function value_coerce_constants() which coerces
484 constant integers as following: if one is a constant and
485 the other is not, the constant's type is set to the type
486 of the other argument. If both are constants and one is
487 signed, the other is converted to a signed constant.
489 Sat Jun 29 17:26:29 EDT 1991
491 valarith.c Added a better range checker. It now checks range
492 (successfully) on integral operations [+-] (signed and
493 unsigned) for any C sized type. Still does not work well
495 int_in_size() returns an integer that is coerced to fit into
496 specified number of bytes.
498 Mon Jul 1 13:04:14 EDT 1991
500 language.[ch] Added the function binop_result_type(), which returns the
501 builtin (struct type *) type that would be the result of a
502 binop on the two values V1 and V2.
504 Wed Jul 3 19:22:53 EDT 1991
506 source.c Extended source_info() to include the source language in
507 the output from "info source".
509 Fri Jul 5 13:48:52 EDT 1991
511 utils.c Moved the support functions for the GDB set/show commands
512 dealing with language into language.c.
513 language.c Added the function language_info(), which displays info
514 about the current working language, type and range check
515 settings. Called via the GDB command "info language".
516 Added an initialization routine _initialize_language(),
517 that sets defaults for the language, type and range
518 variables and sets up the new GDB commands.
519 main.c Language setup moved to language.c.
522 Mon Jul 8 10:10:22 EDT 1991
524 valarith.c Debugged the range checker for arithmetic. Still does not
525 work for multiplication very well.
527 Mon Jul 8 12:40:37 EDT 1991
529 language.[ch] Added the function value_true() which returns non-zero if
530 its argument represents a boolean true value.
531 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
532 check the truth of an expression.
534 Thu Jul 11 12:51:34 EDT 1991
536 language.[ch] Added the predicate structured_type(), which returns
537 non-zero if the argument is a structured type.
538 Added the predicate pointer_type(), which returns non-zero
539 if the argument is a pointer type.
540 eval.c Added the ability to do addition and substraction on
541 pointers and integers. This case simply bypasses the
544 Thu Jul 11 14:41:42 EDT 1991
547 Added the symbol N_DEFD (0x4a) which is a definition
548 module dependency that is used by the GNU Modula-2
549 compiler and the linker. It is not important to GDB,
550 except that [dbx|coff|mips]read.c should ignore these
553 Fri Jul 12 16:07:00 EDT 1991
555 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
556 0 in val_print(). Also added statements to the else part
557 to coerce type (argument to val_print) to a pointer type
558 if it is an "array of unspecified length".
559 valops.c Added the function value_m2_string(), which returns a
560 (value) value which is a constant string, whose type is
561 (ARRAY [0..n] OF CHAR). The length field of the type
562 structure is set to zero, so it will be interpreted as an
563 "array of unspecified length".
564 stack.c Moved the language/frame mismatch check to
565 main.c:execute_command().
566 main.c The working language is recorded each time
567 execute_command() is executed. If working lang has
568 changed during its execution, then the new
569 language/type/range info is printed out for the user. If
570 the working language does not match the language of the
571 frame, a warning is issued.
573 Sat Jul 13 16:16:39 EDT 1991
575 eval.c Moved all the type-checking stuff for operators to
576 language.[ch] language.c. This is so we can keep language-specific
577 stuff (like for what type operators are defined) in
579 language.[ch] Added the function binop_type_check(), which checks to see
580 if its two (value) arguments are type-compatible with its
581 opcode argument. The opcode should represent an operation
582 involving an operator. Also added the macro function
583 unop_type_check, which calls binop_type_check with a
584 NULL second argument.
585 expprint.c Added Modula-2 operators to the op_print_tab, so info
586 expression.h break works correctly. Also added "op_string", which
587 returns the string corresponding to the (enum exp_opcode)
588 opcode that is its argument.
591 Sat Jul 13 18:26:18 EDT 1991
593 coffread.c Added code to record the type of function arguments with
594 each paricular function. Code is very similar to that
596 dbxread.c Moved add_param_to_type() to symtab.c
597 symtab.[ch] Added function add_param_to_type() from dbxread.c
599 *** NOTE: The above additions have not been tested.
601 Mon Jul 15 12:50:47 EDT 1991
603 langauge.[ch] Added the functions type_error and range_error, which work
604 like error() except if the type/range mode is set to
605 *_mode_warn, then they do not do a return_to_top_level(),
606 but merely print a warning.
607 Also changed [set|show]_[type|range]_command() to support
608 the new "warn" feature.
610 Thu Jul 18 17:50:54 EDT 1991
612 mipsread.c Added code to record the type of function arguments with
613 each particular function. Code is very similar to that
616 *** NOTE: The above additions have not been tested.
618 Fri Jul 19 11:19:10 EDT 1991
620 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
621 UMIN_OF_SIZE, which when given a size of a numeric type,
622 return the maximum and minimum value it can hold. UMAX...
623 and UMIN... return the result for unsigned types.
624 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
625 struct types. They call above macros.
626 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
627 avoid a name conlict with the above.
628 c-exp.y Added range checking on numeric constants in
629 parse_number() for completeness.
630 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
631 return 0 if working_lang is not language_c.
633 Thu Aug 8 14:17:22 EDT 1991
637 breakpoint.c Documentation strings of some commands changed to
638 eliminate the references to the C language where
641 Tue Aug 13 15:48:03 EDT 1991
643 m2-exp.y Added qualified identifiers to the grammar. The semantics
644 are slightly different from those of the GDB operator ::
646 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
647 type_exp, where type_exp is any valid type expression.
649 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
650 printcmd.c Modified ptype_command() so it actually parses the input
651 (necessary for type expressions with scope qualifiers).
652 Added the function ptype_eval() which expects an
653 expression composed of one OP_TYPE element.
654 *.[ch] Replaced all occurences of parse_c_expression with
656 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
658 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
660 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
662 Small fixes from Peter Schauer:
664 * infrun.c (child_attach): Lint.
665 * solib.c (find_solib): Handle shared libs version 2.
667 Small fixes from David Wood:
669 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
673 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
674 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
676 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
677 chars_per_line is at maximum (user typed `set width 0'). Fix
678 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
680 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
682 * coredep.c: include ptrace.h where necessary.
683 * mipsread.c(parse_lines): fix unsigned char problem that was
684 messing up line numbers on SGI's and possibly other MIPS based
686 * infrun.c (child_create_inferior): use better test to check
687 return val from setpgrp().
688 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
689 for sgi/irix support.
691 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
693 * mipsread.c (parse_symbol): Put non-static procedures
696 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
698 Patch together `text_start' and `text_end' for 29K port.
700 * exec.c (exec_command): If NEED_TEXT_START_END, define the
701 variables and set them based on the exec file.
702 * am29k-tdep.c: declare text_start.
703 * valops.c (call_function_by_hand): declare text_end.
705 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
706 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
707 because machines that do this will also have to know to
708 set NEED_TEXT_START_END. Besides, it was a redundant way to
710 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
711 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
714 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
716 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
718 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
719 Pass MUNCH_DEFINE to munch whenever we run it.
720 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
721 format string; use 0x%x instead.
722 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
723 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
724 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
725 * inflow.c: Handle `short' process group IDs.
726 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
727 and check for ptrace errors.
728 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
729 (coff_symfile_init): Initialize text_bfd_scnum.
730 (read_coff_symtab): Use it to find the text [and absolute?] sections.
731 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
732 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
733 Merge target arm case with other "easy" cases. Add target
734 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
735 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
737 * minimon.h, remote-adapt.c, remote-mm.c: Add.
738 * munch: Cope with RT/PC putting fns in data segment.
739 Restore ability to override `nm' by specifying MUNCH_NM.
740 * xconfig/rtbsd, xconfig/ultra3: New host systems.
741 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
742 and remote-adapt. Remove encapsulated coff #define's (the
743 support should go in BFD, and gdb shouldn't know or care).
744 * tconfig/a29k-kern: Same, but for remote kernel debugging.
745 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
746 * tm-29k.h: Update BADMAG (though it should go away).
747 Allow the register definitions to be overridden in another
748 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
749 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
750 DUMMY_SAVE_GR96, for handling kernel calling conventions
751 that use GR64+ rather than GR96+.
752 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
753 remote debugging of Ultra3 kernel. Includes tm-29k.h and
754 overrides various things.
756 * remote-mm.c (mm_attach, mm_wait): Handle attach like
757 child_attach does, making a clean stop in the newly attached
761 * coffread.c: Make coffread independent of any particular
762 variant of COFF. Avoid #include-ing any particular one except
763 internalcoff.h. BFD now passes key values for symbol reading
764 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
765 and the symbol masks and shifts); use them.
766 Remove obsolete end_of_text_addr.
768 * exec.c: Remove unused include files.
770 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
772 * Makefile.in (documentation targets): Pass $(M4).
773 Bugfix from eggert@twinsun.com (Paul Eggert).
775 * stack.c (down_silently_command): Check for stack existence.
777 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
779 * Makefile.in (VERSION): Update to 4.0.3.
781 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
783 * core.c (core_file_command): Print frame at coredump with
784 its level number, by calling print_stack_frame.
785 * frame.h: Add selected_frame_level, print_stack_frame.
786 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
787 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
788 Change print_sel_frame and print_selected_frame callers to
791 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
792 * symfile.c (free_named_symtabs): Ditto.
793 * main.c (main): wrap_here needs an arg.
794 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
795 (solib_add): Avoid noise.
796 (solib_create_inferior_hook): Lint.
797 (sharedlibrary_command): Move dont_repeat to here.
798 * utils.c (error): Call wrap_here to force buffered output.
800 Small patches from Peter Schauer:
802 * coffread.c (start_symtab): Free any existing line_vector before
804 (read_coff_symtab): Ditto for type_vector.
806 * source.c (lines_to_list): New variable, replacing function.
807 (all uses): Use as variable.
808 (_initialize_source): Add 'set listsize' and 'show listsize'.
809 * utils.c (lines_to_list): Remove function.
810 * stack.c (print_frame_info): Use as variable.
811 * defs.h (lines_to_list): Remove declaration.
813 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
815 * breakpoint.c (insert_breakpoints): Restore warning about
816 the program might be running in another process, but only for
817 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
818 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
820 * utils.c (error): if error_pre_print is set, print the string
822 * main.c (main, print_gnu_advertisement, print_gdb_version):
823 Reformat legalese so it always prints, but acts as an "I'm here"
824 message while symbols are being read. If any errors occur,
825 print a few newlines to set off the message and start it at the
826 left margin. Remove mention of "help" command, and don't yak
827 about symbol reading.
828 (catch_errors): Error string is now printed first in case of
830 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
831 suggest the "help" command.
833 * Makefile.in (VERSION): Set to 4.0.2.
835 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
837 * .gdbinit: Remove useless "rr" command. Set complaints
838 to 1 for people debugging gdb.
840 * breakpoint.c, remote-vx.c: Reword strings printed by
841 catch_errors callers.
843 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
845 * WHATS.NEW: "history write -> history save". Doc "write on/off".
846 (Fix from kenc@viewlogic.com.)
848 Fix some infrastructure to be able to cope with host and target
849 machines with different sized basic types (ints, ptrs, etc).
850 (Idea from pierre@la.tce.com (Pierre Willard).)
852 * values.c (value_from_longest): Rename from value_from_long.
853 Handle pointer types as well as integers, so that targets with
854 different pointer sizes from the host can be accomodated.
855 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
856 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
857 uses of value_from_long to value_from_longest.
858 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
859 the correct pointer type to value_from_long{est}.
861 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
863 * remote-vx.c: Remove obsolete code for calling functions via
864 vxworks kludge interface (it referenced value_from_long).
866 * valops.c (value_string): Find malloc with lookup_misc_func, not
869 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
871 Make writing to files work properly. (Fixes to BFD are also needed.)
873 * core.c (core_open): Open file ourselves, read or r/w, depending on
874 write_files. Use bfd_fdopenr.
875 * gdbcore.h (write_files): New variable.
876 * exec.c (write_files): Define variable, add set&show for it.
877 (exec_file_command): Use write_files to open for read or r/write.
879 Make shared library reading happen automatically. These changes
880 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
882 * inferior.h (stop_soon_quietly): Add to exported variables.
883 * infrun.c (child_create_inferior): call solib hook, if defined.
884 (child_attach): call solib hook, if defined.
885 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
886 (find_solib): Use lookup_misc_func rather than hand-rolled.
887 (symbol_add_stub): New stub for catch_errors.
888 (solib_add): Avoid output if !from_tty. Catch errors rather
889 than just calling symbol_file_add and bombing.
890 (solib_create_inferior_hook): Interface with the target process
891 to let it read and alloc shared libs, then figure out what it did.
893 * core.c (validate_files): Fix typo, soften warning.
894 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
896 * utils.c (fputs_demangled): Avoid duplicate printing if
897 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
899 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
900 (Fix from pierre@la.tce.com (Pierre Willard).)
902 * main.c (catch_errors): Change argument to a char * from an int,
903 since a char * can point to a struct full of glop, but an int
904 is not guaranteed to be able to hold a pointer.
905 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
906 breakpoint_re_set_one, breakpoint_re_set): Adapt.
907 * core.c (core_open, solib_add_stub): Adapt.
908 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
910 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
912 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
913 by adding .NOEXPORT target.
915 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
919 * Makefile.in (VERSION): Roll to 4.0.
920 (gdb.tar.Z): Make refcard.ps as well, for shipment.
922 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
924 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
927 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
930 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
932 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
933 reflect above name change
935 * WHATS.NEW: correct pointer to refcard.
937 * doc/gdb.texinfo: update New Features, Installing
939 * doc/gdbint.texinfo: add short description of configure +template
941 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
943 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
945 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
947 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
948 tar file, add dependencies for referenced doc files.
950 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
952 * coffread.c, symfile.c, stack.c: saberized.
954 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
956 * doc/refcard.tex: permuted Essential Commands sec
958 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
960 set/show symbol-reloading
961 default set complaints 0
963 RET-repeat disabled after prompted long displays
964 processID (attach) interpretation of 2nd GDB cmdline arg
966 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
968 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
969 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
970 breakpoint.c, main.c: lint.
972 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
974 Install new configuration scheme for GDB and friends.
976 * config.sub: Translate ordinary names to three-part names.
977 * configure: Use three-part names internally.
978 * configure.in: Translate three-part names to filenames.
980 * README, WHATS.NEW: Update for gdb-4.0.
981 * Makefile.in: Roll VERSION to 3.99.
983 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
985 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
986 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
987 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
988 to single structures rather than arrays; when passing
989 their address, use &. This avoids trouble with bdead compilers.
990 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
991 instead. This avoids portability headaches.
992 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
994 * source.c (open_source_file): Avoid ANSI const bdeath by
995 skipping declaration and then casting result value.
996 * tm-hp300bsd.h: Clarify comment.
997 * utils.c (strstr): Result is const char *; ANSI bdeath.
998 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
999 since system include file defines it differently from "defs.h",
1000 though the two are equivalent for our purposes.
1001 * tconfig/hp300bsd: Add m68k-tdep.o.
1003 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1005 * tconfig/sun*4: Remove warnings about system assembler.
1007 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1009 * mcheck.c: Avoid warning about undeclared abort fn.
1010 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
1011 it causes recursive calls to error() when used in cleanups.
1012 To do so requires that we make it a function, so we do.
1013 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
1014 * utils.c (do_cleanups): Remove the current cleanup from the
1015 chain *before* calling it, in case error() is called from it.
1016 The result won't be pretty, but won't be an infinite loop either.
1018 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
1020 * dbxread.c (read_struct_type): Grok anon structs for C++.
1021 (vb_name, vptr_name): Null terminate these strings.
1023 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1025 Minor bug fixes from BSD Net2 gdb:
1027 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
1028 returns 0, there is no previous frame.
1029 * breakpoint.c (commands_command): If !from_tty, don't call
1030 input_from_terminal_p().
1031 * dbxread.c (record_misc_function): Speed up slightly.
1032 (compare_psymbols): Ditto.
1033 * infcmd.c (do_registers_info): Take a second argument to
1034 determine whether to print float registers. "info registers"
1035 does not do so anymore. "info all-registers" does, now.
1036 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
1038 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
1039 * inflow.c (initialize_inflow): Set tflags_ours correctly.
1043 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
1044 executing_breakpoint_commands if we are interrupted by error.
1045 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
1046 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
1047 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
1048 catch_errors() so we can setup the frame regardless of whether
1049 the shared libs work.
1050 * ieee-float.c (double_to_ieee_extended): Get exponent from
1051 right place in little-endian systems. From John Carey.
1053 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1055 * main.c: Remove unused terminating_signals and catch_termination().
1056 (long_options): Terminate with a zero element.
1057 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
1058 (gdb_readline): Make call-compatible with readline.
1059 (init_signals): Improve comments re vfork vs. signal.
1061 * utils.c (prompt_for_continue): Use new gdb_readline().
1062 If we prompt for continuation, we don't let CR repeat the previous
1063 command, once we get back to a prompt. It's too easy to keep
1064 hitting CR, expecting "--more--" prompts, and have some long
1065 command start repeating on you.
1067 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1069 * blockframe.c (frameless_look_for_prologue): Speed up by
1070 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
1071 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
1072 Define two variants, one faster.
1073 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
1074 and return zero, rather than giving an error.
1075 (setup_arbitrary_frame): Initialize the PC in the new frame.
1076 (skip_prologue): Add a second arg saying whether we're just
1077 checking for a frameless function or not.
1079 * core.c (core_open, core_close, core_xfer_memory): Move
1080 section table pointers and bfd* into the target_ops.
1081 (core_open): Allow errors in shared lib reading, etc.
1082 (core_files_info): Describe shared library sections.
1084 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
1085 exec_files_info, set_section_command): Move section table
1086 pointers and bfd* into the target_ops.
1087 (add_to_section_table): Add BFD to section table.
1089 * target.c (target_xfer_memory, target_info): Pass target to
1090 xfer_memory and target_info functions.
1093 * gdbcore.h: Move struct section_table.
1094 * target.h: New home of struct section_table.
1096 * solib.c (solib_add): New argument is the target_ops whose
1097 section list is to be added to, if any. Reallocate the
1098 sections in that target to add any that come from shared libs.
1099 (throughout) so_sections renamed to sections.
1100 (solib_xfer_memory): Deleted.
1101 * tm-sunos.h (SOLIB_ADD): Add target argument.
1102 (SOLIB_XFER_MEMORY): Delete.
1104 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1105 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
1106 from target_ops. It's the same on all targets. Add two section
1107 pointers to target_ops.
1109 * stack.c (find_relative_frame): Dump ancient algorithm for
1110 "down", just use handy "next" pointers.
1111 (frame_command): Don't error if there is no stack; let user
1114 * inflow.c (new_tty_prefork, new_tty): New prefork routine
1115 modifies static state in the parent process; new_tty itself
1116 runs in the child and modifies the child's file descriptors
1117 to match the saved static state.
1118 * infrun.c (child_create_inferior): Call new_tty_prefork,
1121 * infptrace.c (child_xfer_memory): Add ignored target arg.
1122 * remote-eb.c (eb_xfer_inferior_memory): ''
1123 * remote-nindy.c (nindy_xfer_inferior_memory): ''
1124 * remote-vx.c (vx_xfer_memory): ''
1125 * remote.c (remote_xfer_memory): ''. Rename from
1126 remote_xfer_inferior_memory.
1128 * main.c (main): Only try to attach "corefile" argument if
1129 it starts with a digit.
1131 * symfile.c (symbol_reloading): New "set/show" variable.
1132 (symbol_file_add): Shorten message about symbol reading.
1133 (add_symbol_file_command): Merge with add_syms_addr_command,
1134 since this should work on all targets now.
1135 (stop_whining): Default to zero, to shut up complaints
1136 about bad symbol tables on many systems.
1137 (free_named_symtabs): Just exit unless symbol_reloading.
1139 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
1140 and add comment explaining shared library screw.
1142 * source.c: #if defined => #ifdef.
1144 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1146 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
1148 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1150 * doc/rdl-apps.texinfo: provide default readline-appendix finder
1151 (doc/Makefile knows how to make one for local config)
1153 * Makefile.in: use doc/Makefile for doc targets
1155 * doc/Makefile: GDB documentation now has its own Makefile
1156 doc/refcard.tex: renamed from "gdbrc.tex"
1157 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
1158 doc/gdbint.texinfo: add markup in "Cleanups" chapter
1161 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1163 * values.c (baseclass_addr): When reading target memory, use the
1164 length of the basetype, not the upper type. We've only malloc'd
1165 enough space for the basetype, leading to errors in free().
1167 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
1168 ends up as a function specially, since we know the actual type of
1169 the pointed-to address. This (somewhat) fixes display of
1170 expressions that include misc_function_vector names. Try `cond 1
1171 !strcmp("a","b")' then `i b'.
1173 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
1174 The child can be proceeded from inside wait_for_inferior in
1175 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
1176 getting skipped in that case.
1178 * expprint.c (print_subexp): Use filtered output, since the
1179 subroutines we call use it, otherwise the output is horribly
1180 mangled, since output of wrappable stuff comes out late.
1182 * Makefile.in: Bump VERSION to 3.98.1
1184 * infrun.c (child_create_process): Use execlp to find the
1185 shell to exec our target program. This requires some fiddling
1186 with `environ' since there is no execlpe().
1188 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1190 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
1191 Minor rearrangement of refcard permits two new make targets--
1192 gdbrc.dvi DVI output for refcard, using CM fonts
1193 gdbrc.ps PostScript refcard, using PS fonts
1195 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1199 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
1200 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
1202 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1204 * doc/gdb.texinfo: last changes for release.
1205 Minor typo and formatting fixes; incorporated most fixes remaining from
1206 filed mail commenting on earlier drafts.
1208 Added warnings: pipes don't work in run command;
1209 conditions are converse of assertions;
1210 step over fn without debug info goes to next fn;
1211 vars may have "wrong" values near fn entrance, exit
1213 Added example from Kingston on printing repeated nonadjacent values
1215 Added explicit mention that in Emacs gdb mode C-c and C-z are like
1216 shell mode for signals
1218 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
1219 doesn't sound so much like its parent "Stopping and Continuing"; also
1220 moved entries on continue to top of section, so they don't get lost.
1222 Improved installation directions in appendix, added manual formatting
1225 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1227 * configure.in: Remove xm.h and tm.h even if we aren't linking
1228 new ones, so "./configure sun4; ./configure none" does the right
1229 thing. Assume that alldeps.mak and depend are already built in
1230 srcdir, and avoid running "make" (particularly "make depend",
1231 which involves "gcc") from inside configure. Build Makefile
1232 directly rather than building Makefile.conf first.
1233 * configure: Regenerate with above changes.
1234 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
1235 to 3.98. Revise gdb.tar.Z procedure to produce a file
1236 called gdb-$(VERSION).tar.Z but which unpacks into a
1237 directory called "gdb". Move non-source files out of
1238 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
1239 (depend): Don't try to do "gcc expread.y".
1240 (expread.o): Update dependencies by hand.
1242 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1245 Fixed a variety of small typos that prevented info from formatting
1246 cleanly; altered too-long heading for GPL Appendix, as discussed
1247 w/RMS; Changed date on cover to July 91.
1249 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1252 (1) Applied some fixes due to comments from Larry Breed (easier ones
1253 through chapsec 5.2)
1254 (2) Eliminated use of @footnote---had my doubts about it anyways, and
1255 it's broken in latest texinfo
1256 (3) Introduced *some* use of [] for optional arguments, where
1257 explanation is not simpler by listing cmd w arg and cmd w/out arg
1258 separately. Still not using @deffn.
1259 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
1260 couple of headings are too long. Need patches to texinfo or revision
1263 * Partial update to README (which still needs work for this
1264 release!): (1) use of configure corrected for new script,
1265 (2) "make gdb.dvi" and "make gdb.info" mentioned.
1267 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
1269 * symtab.c (lookup_symbol): Don't complain right off about
1270 no debug symbols; use the misc function vector first.
1271 (list_symbols): Use misc function vector to find symbols
1272 that don't have debug info, and print them.
1273 (find_pc_symtab): Temporarily avoid fatal() when psymtab
1274 PC range doesn't match symtab PC range, as it does on the
1275 MIPS because our symtab reading isn't perfect.
1277 * dbxread.c (dbx_symfile_read): Make warning about
1278 "no debug symbols" slightly nicer.
1280 * source.c (select_source_symtab): If "main" symbol exists,
1281 but decode_line_spec can't find line info, don't just return
1282 a zero; try other source symtabs or give an error.
1284 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
1285 their low addresses first, then rip through fixing high addrs.
1287 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
1288 <runene@ifi.uio.no>.
1289 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
1291 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1293 * Minor, mostly mechanical, cleanup of doc subdir for clean
1294 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
1295 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
1297 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
1299 Mostly MIPS and general symbol-reading fixups.
1301 * doc/gdbint.texinfo: Add documentation on symbol-reading
1304 * mipsread.c: Remove kludges around #include "ecoff.h".
1305 Remove redefinitions of a_magic, etc, no longer used.
1306 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
1307 Fix global overview comments to match symfile.c protocol.
1308 (mipscoff_new_init): Eliminate cur_hdr if we have one.
1309 (mipscoff_symfile_read): Eliminate unused code. Avoid
1310 sorting all the symtabs, when all we have read here is psymtabs.
1311 The symtabs are sorted as they are created anyway. Tell
1312 condense_misc_bunches whether we're mainline.
1313 (psymtab_to_symtab_1): Pass filename when recursing, to make
1314 stack trace more informative.
1315 (parse_partial_symbols): Assume cur_hdr as argument.
1316 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
1317 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
1318 the TYPE_NAME of char *, since that's done in symfile.c.
1319 (free_numargs, parse_symbol, add_symbol, add_block,
1320 shrink_linetable): Declare these fns void.
1321 (upgrade_type): Convert tree of if's to switch. Clean up
1322 bogus "off == 0" handling with a complaint. Avoid setting
1323 field bitpos and bitsize of array with lower and upper bounds.
1324 Check specified bitsize of elements against their actual type's
1325 bitsize, and complain if different. Complain about unknown
1327 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
1328 (psymtab_to_symtab_1): Print names of subsidiary files that
1329 are being read in. FIXME, we read far too many files. This code
1330 is not the problem, the problem is in parse_fdr where the psymtabs
1332 (cross_ref): Result should indicate that we used one aux entry
1333 normally, or two if we encountered a "next" entry. This used
1334 to leave the caller pointing at the wrong aux entry.
1335 (add_symbol): If overflowed cur_block, reallocate it larger,
1336 chase all pointers to it, and complain(), rather than clobber memory.
1337 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
1338 (new_field): Only allocate one field initially, not two.
1339 Pull ++ out of macro argument. Simplify.
1340 (_initialize_mipsread): Avoid initialization of importd
1341 global_psymbols and static_psymbols.
1343 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
1344 to properly set pst->symtab; avoid searching for it.
1345 (symfile_fns): Improve comments, add a FIXME.
1346 * dbxread.c: Update comments to reflect symfile protocol.
1347 (read_ofile_symtab, end_symtab): Return the symtab.
1348 (psymtab_to_symtab_1): Set pst->symtab.
1350 * coffread.c (coff_symfile_read): tell condense_misc_bunches
1351 whether we're mainline.
1353 * symfile.h (sym_fns): Remove unused sym_discard member.
1354 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
1356 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
1357 the environment variable is not.
1358 * infcmd.c (finish_command): Use filtered printfs.
1359 * cplus-dem.c: Add struct tags to a few unnamed structs.
1360 * valops.c (value_coerce_array): Improve comments.
1361 * valprint.c (type_print_varspec_suffix): Print array size only
1362 if greater than zero.
1363 * m88k-tdep.c: Shift some lines left by one space, that had
1364 apparently been trashed at some point.
1365 * TODO: More things to do, a few got done.
1367 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1369 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
1370 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
1372 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
1373 * expread.y, findvar.c, symmisc.c: Ditto.
1374 * printcmd.c (address_info): Update printed forms of LOC_
1375 symbols. Elim LOC_EXTERNAL.
1376 (print_frame_args): Keep track of param stack offsets before
1377 re-looking up to find the local register param is kept in.
1379 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
1380 Further integration of mipsread into gdb. Eliminate unused
1381 routines, duplicate declarations. Handle static symbols in
1382 psymtabs as well as external symbols. When reading symtabs,
1383 insert symbols into the correct block (global, static, or a local
1385 (read_mips_symtab, parse_partial_symbols): Don't pass useless
1387 (mipscoff_symfile_read): Don't call select_source_symtab.
1388 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
1389 rather than SYMBOL_VALUE.
1390 (parse_external): Comment clobbering of top_stack.
1391 (parse_partial_symbols): Update comments. Allocate and parse
1392 static symbols as well as external symbols. FIXME, enum values
1393 are not handled in this pass, but should be. Inline new_psymbol.
1394 Use SYMBOL_VALUE_ADDRESS.
1395 (psymtab_to_symtab_1): Read symbols into global static block
1396 by default (until enter some function's local block context).
1397 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
1398 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
1400 * source.c (select_source_symtab): Select a source symtab
1401 from either the symtabs or, failing that, the psymtabs.
1402 (list_command): Update error message.
1403 (forward_search_command, reverse_search_command): Use getc, not
1404 fgetc, for speed. FIXME, add comment about buffers that die if
1405 overrun by long line.
1407 * values.c (unpack_field_as_long, modify_field): Avoid shifting
1408 by an entire word, which is not portable, if we have a 32-bit
1409 field. (Code in dbxread.c already turns such bitfields, if
1410 aligned, into ordinary ints, but fixing this will help for other
1411 symbol formats and for future changes.)
1412 * core.c (core_open): Handle ANSI const brain death.
1413 * utils.c (vprintf): Fix varargs typo.
1415 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1417 * findvar.c (find_var_value): Handle &function better.
1418 * TODO: Document work needed on &fn and &array.
1419 * printcmd.c (print_address_symbolic): New arg is the prefix
1420 to print if a name is printed.
1421 (print_address_demangle): Honor "set print address" now.
1422 Use new arg above to improve spacing of output.
1423 * valprint.c (val_print): When printing function pointers,
1424 print symbolic form too.
1425 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
1427 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1429 * core.c (memory_error): Reword error msg to mislead less.
1431 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
1433 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
1434 parse_partial_symbols): Use newer BFD internals (external_filehdr
1435 and external_aouthdr), byte-swap the fields that we care about
1436 before using them, and make the file header data local to
1437 read_the_mips_symtab rather than global.
1439 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
1441 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
1442 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
1444 * main.c (command_line_input): Flush stdout and stderr
1445 before every call to readline. This reportedly fixes a bug
1446 that comes up in Sys V running emacs-gdb and/or xxgdb,
1447 when stdin/out are pipes or sockets.
1449 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1451 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
1452 Avoid declaring Makefile dependencies, because GNU Make stupidly
1453 tries to update it if we do.
1455 * coffread.c: Revise for minor changes to bfd internal coff
1458 * configure: If -template= is given a relative path, make it
1459 absolute before recurring in subdirectories.
1461 * configure, configure.in, Makefile.in: Install "configure" script
1462 as replacement for config.gdb.
1463 * config.gdb, Makefile.dist, Makefile.sdir: Remove
1464 * README: Update for configure, mostly. FIXME.
1466 * Add dec3100 as equivalent to littlemips. Indicate in all host &
1467 target config files that they are for the host. When the lines
1468 get copied into the Makefile, this makes it more obvious what's
1471 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1473 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
1474 tabs, which end up in the disassembler output inadvertently.
1476 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1478 Make it compile cleanly in an ANSI GCC2 environment.
1480 * blockframe.c: <stdio.h>
1481 * cplus-dem.c: free takes a void *, ifdef __STDC__
1482 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
1484 * defs.h (alloca): Avoid doing anything if alloca already def'd.
1485 * stddef.h, stdlib.h: Remove these files.
1486 * symtab.c: Avoid declaring qsort, close.
1487 * symfile.c: Avoid declaring close.
1488 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
1489 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
1491 Assorted other changes.
1492 * dbxread.c: include "libaout.h", not "liba.out.h".
1493 * printcmd.c (print_frame_args): Set recurse properly for
1494 indentation of struct and array parameters.
1495 * valops.c (value_cast): Allow cast to void.
1496 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
1497 single_step() in a target-independent fashion.
1498 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
1499 set up to be ready to continue. This makes us target independent.
1500 * infptrace.c (child_resume): Remove call to single_step; now
1501 can single step a SPARC target of any kind.
1503 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1505 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
1506 docn into separate sections---basically chapters, plus two loose
1507 pieces that can be configured to go in different places. This
1508 allows GNU m4 to preprocess the manual without coredumping.
1510 * Makefile.dist: tell TeX where to find texinfo.
1512 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1514 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
1515 the new target "rdl-apps.texinfo" which captures the Makefile
1516 variable that records where to find the Readline libraries.
1518 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
1520 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
1521 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
1522 * defs.h (const, volatile): Only define if not already defined.
1523 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
1525 * README: Update for release 3.95.
1526 * config.gdb: Don't create readline dir in subdir builds.
1527 * main.c: Include with "..." form for non-system include files,
1528 so "gcc -MM" for "make depend" works.
1529 Include readline files with "...h" rather than <readline/...h>.
1530 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
1532 * coffread.c: Undo minor damage done by Rich Pixley. Use
1533 different internal and external representations of COFF
1534 data structures. Use new BFD routines for swapping them in and
1536 * symfile.c (free_named_symtabs): Avoid freeing file names that
1537 are null or empty. Old i960 tools seem to produce files that
1538 claim to have empty names, causing each successive file read
1539 to blow away the previous one.
1540 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
1541 Move deferred_stores to top of file, but don't separate its
1542 #define's from its variable. Add commentary.
1543 * Makefile.dist: Fix Rich damage; undo "configure" changes in
1544 favor of keeping the (working) config.gdb. Move readline
1547 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
1549 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
1551 * infptrace.c (fetch_registers): no result, since now void.
1552 * tconfig/news: target depends on m68k-tdep too.
1554 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1556 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
1559 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
1560 applied various small fixes due to or inspired by RMS comments
1562 * doc/gdb.texinfo: finished using all RMS comments, save those for
1563 appendices on readline and cmd history (which are in other source
1566 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1568 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
1569 chapter 9; (2) documented 'break' command's menu mode for
1570 overloaded names, in response to hgs problem report C++ p-31
1572 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1574 * doc/gdb.texinfo: (1) better introductory example; (2) more
1575 consistent use of @code, @samp, @file, @kbd throughout; small
1576 cleanups to first three nodes; (3) new "Contributors" node;
1577 (4) Appendix, Renamed Commands; (5) divert specialized startup
1578 instructions to "Targets" chapter for generic manuals, while
1579 leaving them up front for manuals specific to specialized
1580 environments; (6) apply fixes from RMS comments through chapter 4.
1582 * pretex.m4: modify explanatory text slightly (and redefine
1583 "regexp") to keep GNU m4 from complaining. (It still crashes
1584 later, but one step at a time...)
1586 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
1588 * readline/readline.c (update_line): Avoid dereferencing a pointer
1589 before comparing it to its bounds. Saber caught this.
1590 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
1591 and only set PC if tgetstr returned non-null. Saber caught this.
1593 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1595 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
1596 stuff for config manual) here where it counts; updated
1597 to use new subdir structure (gdb/doc/).
1599 * Makefile: generated from above via
1603 * gdbint.texinfo: added instructions on generating gdb.info* files
1604 locally for release. These are ordinary info
1605 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
1606 Makefile)---but due to use of texinfo 2, can't count on makeinfo
1607 to generate these, so we distribute them already formatted.
1609 * gdb.texinfo: included full Info node and menu crud (as generated
1610 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
1612 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
1613 put in comments-for-future gdb.info target (one day makeinfo will
1616 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1618 * gdb.texinfo: Updated to include new or old undocumented
1619 commands, at least the following (perhaps some others I forgot to
1620 record): info f, info float, info path, info program, info s, info
1621 set, info source, info terminal, info types, info user, set/show
1623 Also covered all recent GDB command renames for v4.
1625 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1627 * mipsread.c: Rather than keeping count of how many symtabs
1628 and psymtabs we have, for sorting purposes, count them when
1629 we need to sort. This fixes bug in rereading of symbol tables.
1631 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1633 * infcmd.c: renamed "info path" to "show paths"

1647 * coffread.c, exec.c, infptrace.c, inftarg.c, remote.c, solib.c,
1648 symtab.h, target.c, target.h: Lint.
1649 * core.c: setup and select frame after reading shared libs,
1650 else reading shared libs will clobber them. Lint.
1651 * utils.c (error): Force out any buffered wrap text.
1653 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1655 * remote.c: Remove decls of memory_insert_breakpoint
1656 and memory_remove_breakpoint, no longer used. (Suggestion of
1659 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
1660 to make it easier to interface to "configure"'d libraries.
1662 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
1664 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
1665 aliases for set/show print.

2177 core.c, exec.c, remote-eb.c, remote-nindy.c, remote-vx.c,
2178 remote-vx.68.c, inftarg.c, remote.c: Add doc field to target struct.

2208 command is add-symbols.
2209 * target.c (dummy_target): Permit add_syms_addr_command.
2211 Sat Apr 13 14:46:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2213 Permit symbols to be superseded when new symbol files have
2214 been read in, particularly for VxWorks.
2216 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
2217 to the main file, as well as to include files. Also, put global
2218 functions into the global psymtab, to make "i fun" work.
2219 (end_psymtab): Free named symtabs and psymtabs for a file, once a
2220 new psymtab for it has been read.
2221 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
2222 a file, once a new symtab has been read for it.
2223 * mipsread.c: FIXME. We need to do the same for MIPS, but it
2224 looks harder to determine the top-level block before it's been
2225 queued to the psymtab list.
2227 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
2228 If we have wiped out any old symbol tables, clean up at end of
2230 (symbol_file_command): Don't reference symfile_fns if it's zero.
2232 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
2233 defines for the blocks of a blockvector that contain global and
2234 file-static symbols and the first of the smaller scope contours.
2235 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
2236 decode_line_1, make_symbol_completion_list): Use the above.
2237 * coffread.c (end_symtab, patch_opaque_types): Ditto.
2238 * dbxread.c (end_symtab): Ditto.
2239 * expread.y (block): Ditto.
2240 * mipsread.c (throughout): Ditto.
2241 * symmisc.c (free_named_symtabs): Ditto.
2243 * symtab.c (list_symbols): Process the first symbol of the
2244 static psymbols list.
2245 (types_info): Restore this function from its untimely #if 0.
2246 It's not perfect, but it is better than nothing.
2247 (_initialize_symtab): Restore "info types".
2249 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2251 * m68k-stub.c: Remote stub for 680x0's, created from
2252 rem-m68k.shar (which is removed).
2253 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
2254 Remove RCS log stuff now that we use CVS and it blows our diffs.
2256 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2258 * symmisc.c (free_named_symtab): Make it work, in its current
2259 kludgy fashion. Change result to indicate if we blew away bkpts.
2260 * dbxread.c (end_symtab): Accumulate result from
2261 free_named_symtab and print warning if we blew user's state.
2262 * symfile.h: free_named_symtab now returns an int.
2264 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
2266 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
2267 is the first symbol read, even if not mainline.
2268 (dbx_psymtab_to_symtab): symfile might be zero, cope.
2269 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
2270 (set_section_command): New command ("section xxx yyy" -- should
2271 be renamed to "set section xxx yyy" FIXME) which sets the
2272 base address of a section of the exec file, overriding the
2273 virtual address that BFD reports.
2275 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2277 * exec.c: Add add_syms_addr_command to exec_ops, so you can
2278 load symbols at any address while examining an exec file.
2280 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
2282 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
2283 for printing the float info is host-dependent, not
2284 target-dependent. FIXME.
2285 * i386-pinsn.c: Move #includes to top, remove useless ones.
2286 * i386-tdep.c: Don't bother including <.../reg.h> since we
2287 don't use it (and it doesn't exist on host systems).
2289 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
2290 Convert negative numbers properly.
2291 (ieee_test): Make numbers really random; fix format arg.
2293 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
2294 * core.c (core_detach): Unpush core_ops, which might not be on
2295 top. We used to just pop the top, which broke things. Don't
2296 need dont_repeat() any more.
2297 (core_file_command): Psst! Don't repeat it.
2298 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
2299 * expprint.c (print_subexp): Avoid switch fallthru on
2300 BINOP_ASSIGN_MODIFY, so we can print += and such.
2301 * frame.h: Fix typo.
2302 * inflow.c (kill_command): After killing inferior, print our
2303 current frame in the core file, if we have one.
2304 (generic_mourn_inferior): When inferior dies, either select
2305 the current frame (in the new target, e.g. core file), or
2306 set both the current and selected frames to NULL.
2308 Changes from Peter Schauer.
2310 * infptrace.c: Avoid <sys/ptrace.h> on USG.
2312 * Make all file names fit in 14 characters (sigh and damn!):
2313 mv hp300hpux-xdep.c hp300ux-xdep.c
2314 mv symmetry-xdep.c symm-xdep.c
2315 mv symmetry-tdep.c symm-tdep.c
2316 mv convex-opcode.h convx-opcode.h
2317 mv tm-vxworks960.h tm-vx960.h
2318 mv tm-vxworks68.h tm-vx68.h
2319 mv Makefile.srcdir Makefile.sdir
2320 mv gdb-int.texinfo gdbint.texinfo
2321 mv remote-sa.m68k.shar rem-m68k.shar
2322 mv remote-multi.shar rem-multi.shar
2323 * Makefile.dist, README, config.gdb, convex-pinsn.c,
2324 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
2325 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
2328 * command.c (user_info_1, user_info): New command for listing
2329 the user-defined commands.
2331 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
2333 * dbxread.c (really_free_pendings): Clear file_symbols
2334 and global_symbols after freeing them; otherwise, running
2335 this function twice (if it appears twice on the cleanup
2336 chain), we try to free things twice.
2338 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
2339 based on text_addr (the address of text in core), not on addr (the
2340 offset between text in the .o file and in core). This change
2341 is from Peter Schauer.
2343 * main.c: Define ALL_CLEANUPS as a cast of zero.
2344 (return_to_top_level): Use it.
2345 (main): Do all cleanups after each command run as part
2346 of the gdb startup sequence. Also do all cleanups before
2347 entering the command loop, and every time we exit the command
2348 loop and reenter. Before, the cleanups from the startup sequence
2349 were being left undone until the first error!
2350 (command_loop): Rename do_nothing cleanup to command_loop_marker
2351 so we can see it easily when examining the cleanup chain.
2352 (init_signals): Add another do_nothing for signal handling.
2353 (quit_command): Only try to kill target if it has execution.
2354 Problems in the target stack got us into a state where
2355 inferior_pid was nonzero but none of the targets had execution.
2356 In this state you couldn't exit gdb.
2358 * dbxread.c: Two changes from Peter Schauer.
2359 (echo_command): Fflush output after an echo command.
2360 (show_history): Pass all args to cmd_show_list.
2362 * utils.c (init_malloc): Call mtrace to turn on tracing
2363 if the environment variable MALLOC_TRACE is set to a file name.
2364 * mtrace.c: Add source file which provides a log of every malloc,
2365 free, and realloc to a trace file.
2366 * mtrace.awk: Add source file which analyzes the trace file.
2367 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
2368 (VERSION): Roll to 3.94.3.
2370 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
2371 (check_duplicates): Don't bother with watchpoints.
2372 (set_raw_breakpoint): Comment about danger of this routine.
2373 (watch_command): Parse and eval all args before calling
2376 * solib.c (find_solib): Avoid error in referencing memory to
2377 see if any more shared libraries have been added. This is
2378 particularly useful if the target has terminated. Bug reported
2381 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
2382 in bringing up 3.94.2 on the Sun-3.
2384 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
2385 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
2386 expression (in scope) before reenabling watchpoint.
2387 * signame.c (init_sigs): Add missing declaration of i, fix
2388 sys_siglist declaration.
2389 * source.c (list_command): Fixed range computation to use
2391 * stack.c (backtrace_command): Do not allow command if target has
2392 no stack, print informative error message.
2393 * target.c (target_command): Do not write into command line
2394 because this fails if the target command is used in a user defined
2395 command. [This change was enhanced by gnu to support any-
2396 unique-prefix matching on target names.]
2397 * valops.c (value_struct_elt): Avoid infinite loop on an
2398 erroneous attempt to print the member of function (try p main.p).
2400 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
2402 * expread.y (name_no_typename): Avoid reduce/reduce errors
2403 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
2404 Since the GDB parser really doesn't use name_no_typename in a
2405 name-only context, the parser can't tell the diff between
2406 names and numbers here. Avoid allowing a name_no_typename
2407 to be a NAME_OR_*INT to resolve the conflict.
2409 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2411 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
2413 * valprint.c (val_print_fields): bitfield printing didn't handle
2414 byte order. Indirect through a few more fns to cope.
2416 * values.c (modify_field): also cope with byte order.
2418 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2420 Cleanup for release 3.94.2:
2422 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
2423 include files. Roll version to 3.94.2.
2425 * coffread.c (init_stringtab): Read length into unsigned char
2426 array before swapping; don't assume 32-bit longs.
2428 * target.c (target_info): Don't bother with get_sym_file, just use
2429 the symfile global variable.
2430 * symtab.h, symfile.c (get_sym_file): Delete it.
2432 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
2433 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
2434 (read_type): Replace one more error() with complain().
2436 * mipsread.c (parse_partial_symbols): Replace printf with complain.
2438 * i960-tdep.c: Fix copyright attribution.
2440 * config.gdb: Quote all backquotes in doublequotes. You can
2441 quote me on that. BSD 4.4 shell found this one.
2443 * infptrace.c (throughout): The third argument to ptrace is an
2446 * infrun.c (wait_for_inferior): When program has terminated, we
2447 have to call target_terminal_ours before we pop that target off
2448 the stack (e.g. before a call to target_kill or
2449 target_mourn_inferior). This fixes problem where a program
2450 terminates, then GDB stops for (tty output) and you have to type
2451 "fg" to the shell to resume it. FIXME: This code for what to
2452 do after termination really should be in normal_stop instead.
2454 * gdbcore.h (read_memory_check): Change declaration; it changed
2457 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
2458 4.4 prereleases, this avoids a bug in their sgtty compatability
2460 * remote.c: Use terminal.h rather than hand-rolling the same.
2462 * signame.c, signame.h (psignal): Arg is unsigned, not int.
2463 * utils.c (strsave, strstr): Fix arg types.
2464 * valprint.c (val_print): lint
2466 MIPS symbol table support from Per Bothner:
2468 * symfile.c (symtab_fns): Remove initializer table that needs to
2469 be hacked for each new symbol file format supported.
2470 (add_symtab_fns): New function, chains symbol table
2471 handlers into the global list.
2472 (symfile_init): Search this list.
2473 * symfile.h: Add next pointer, declare add_symtab_fns.
2474 * coffread.c (_initialize_coffread): Call add_symtab_fns.
2475 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
2477 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
2478 symbol *). Thus, we no longer need the hack to trash
2479 pst->filename. Good, since that hack confused code in symfile.c!
2481 (reorder_symtabs, destroy_all_symtabs): Removed static
2482 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
2483 Instead, the latter now uses a temporary array (stack-allocated
2484 from an obstack, and then freed).
2486 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
2487 haven't been set in the outermost stBlock of a procedure. This was
2488 a problem with f77 binaries on Ultrix 4.?.
2490 (new_symtab, new_symbol, new_type): Continue changing code to use
2491 obstacks more and otherwise conform to dbxread internal style.
2492 Made the free_code of symtabs be free_linetable (as in dbxread)
2493 instead of free_contents. This implies memory leaks when reading
2494 a new symbol table, until the conversion is finished. Did change
2495 (struct symbol) and (struct type) to be allocated on the
2496 symbol_obstack. Blocks and blockvectors are among the things
2499 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
2500 tested much, but it solved one problem (reported by Meissner), and
2501 cleans up some other things. The problem happened when an
2502 included file contains actual code (functions) and not just
2503 definitions. The mips coff is a little inconvenient there, since
2504 it may cause a procedure to be mapped to the wrong psymtab.
2506 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
2507 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
2508 this will need work for the new core paradigm.
2510 Opcode patches from the net:
2512 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
2513 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
2514 missing altogether - they are added here. From Bruce Bauman.
2515 * mips-opcode.h: The low mask for C0 instructions was too small.
2516 From Garrett Lau. I modified the fix to check the entire 32-bit
2519 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
2522 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2524 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
2526 * dbxread.c (read_type): Pointer subtraction (value_sub in
2527 valarith.c) sometimes failed because the types of the
2528 pointers being subtracted were not identical.
2529 These differed because dbxread.c was allocating pointer types
2530 using dbx_alloc_type+smash_to_pointer_type instead of
2531 lookup_pointer_type. I failed to find a justification for the
2532 former, so I changed it to use the latter. Similarly, I
2533 replaced smash_to_function_type by lookup_function_type,
2534 and smash_to_reference_type by lookup_reference_type.
2536 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
2537 _initialize_mipsread): corresponding changes.
2539 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
2541 * source.c (mod_path): Do tilde_expand on each component of the path,
2542 rather than on the (list of) paths as a whole.
2543 (print_source_lines): Set first_line_listed in addition to
2544 current_source_symtab and current_source_line. If the source was
2545 not findable, after a "dir" command to fix the problem,
2546 a "list" would get the wrong lines.
2548 While I was there... (gnu):
2550 * dbxread.c (read_type): Change error to complaint.
2552 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2554 First attempt at detailed understanding of symbol table memory alloc.
2556 * dbxread.c (dbx_symfile_read): Free our string table if we
2557 aren't the mainline. Free the "info" struct since we're done with
2559 (init_psymbol_list): Free any previously allocated psymbol lists.
2560 (): FIXME: Should realloc-down the psymbol lists when done reading
2561 the main symbol file?
2563 * symmisc.c (free_symtab): Free fullname field too.
2565 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
2566 (REGISTER_ADDR): Make result type unsigned int.
2568 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
2569 define REGEX must also define REGEX1 (its dependency).
2571 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
2573 * tconfig/i960: No longer works, points you at vxworks960 or
2576 * xgdb.c, XGDB-README: Remove file. Users can get the much
2578 * Makefile.dist: Remove all trace of xgdb.
2580 * breakpoint.c (breakpoint_1): Pass demangle arg to
2581 print_address_symbolic.
2582 (clear_breakpoints): Remove unused function.
2583 (breakpoint_re_set_one): Guts of breakpoint_re_set.
2584 (breakpoint_re_set): Use catch_errors to do them all anyway.
2586 * gdb-int.texinfo (Host versus Target): Add section on what is
2587 a "host" feature versus what is a "target" feature.
2589 * infcmd.c (path_command, path_info): Handle the PATH variable
2590 (object search path) as conveniently as the source search path.
2591 * environ.c (set_in_environ): Set some vars in GDB's environment,
2592 in addition to the child's. PATH, G960BASE, G960BIN for starters.
2593 * source.c (mod_path): New function, from guts of
2594 directory_command, modifies a path. Used by path_command.
2595 (directory_command): Call it.
2596 * defs.h (strsave): Declare.
2598 * utils.c (sevenbit_strings): Add new printing option.
2599 (printchar): Use it.
2600 (strsave): Provide this handy helper routine.
2601 (set_width_command): Rename set_screen_width_command.
2602 (_initialize_utils): "set screen-width" => "set width";
2603 "set screen-height" => "set height"; add sevenbit-strings.
2605 * infcmd.c (do_registers_info): Print floating point registers
2606 in raw hex as well as float format, regardless of whether it is
2607 a "virtual" convertible register.
2608 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
2609 regs as a double, just in case it's being used that way.
2610 * values.c (unpack_long): Comment on array/function coercion.
2611 (unpack_double): Argument is in target byte order now. For
2612 integer arguments, just call unpack_long and float the result.
2613 * m68k-tdep.c: include defs.h for "const" handling.
2614 * remote-nindy.c: Use ieee-float stuff.
2615 (nindy_fetch_registers): Unpack double regs to host double, then
2617 (nindy_store_registers): Pack extendeds to host double, flip
2618 around by misusing unpack_double, send as target double.
2620 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
2621 zero, as when stopped at the first instruction of a process.
2623 * blockframe.c: Fix filename in comment (param.h => tm.h).
2624 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
2625 * tm-68k.h: Fix typos.
2627 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
2629 Changes from a bringup on the DEC Vax under Ultrix 4.0.
2631 * coredep.c (fetch_core_registers): Pass end-address of register
2632 section to register_addr as expected. Don't call supply_register
2633 if we'd just pass it garbage.
2635 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
2637 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
2639 * target.c (push_target, target_info): Cast enums to int for < or
2642 * stack.c (print_frame_info): Identify source file & line
2643 even if we can't print it.
2645 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
2647 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
2649 Clean up IEEE floating point support.
2651 * ieee-float.h: New file.
2652 * ieee-float.c: Write real routines to convert between host
2653 doubles and various target IEEE extendeds.
2654 * m68k-xdep.c: Eliminate assembler code for extended floats.
2655 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
2656 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
2657 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
2658 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
2659 double_to_ieee_extended.
2660 * i960-tdep.c: Define ext_format_i960.
2661 * m68k-tdep.c: Define ext_format_68881.
2662 * sparc-tdep.c: Define ext_format_sparc, though unused.
2663 * Makefile.dist (HFILES): Add ieee-float.h.
2664 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
2667 Obsolete the "coffstrip" program in favor of using BFD's strip.
2669 * nindy-share/coffstrip.c: Remove file.
2670 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
2671 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
2672 * tconfig/nindy960: Remove reference to coffstrip.o.
2674 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
2676 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
2678 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
2679 * dbxread.c: Remove static symfile_bfd.
2680 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
2682 * inftarg.c (child_detach): Pop the child_ops vector if the
2683 detach is successful.
2684 * remote-nindy.c (nindy_create_inferior): Don't push a new
2685 nindy_ops since nindy uses the same one for execution and memory
2687 * core.c (core_ops): Use child_attach and child_create_inferior
2688 rather than default attach and create_inferior functions.
2690 Handle floating point registers in core files.
2692 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
2693 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
2694 This version untested since BFD doesn't yet support sun3 core
2696 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
2697 conventions. Fix comments and style. This version has not
2698 been compiled yet, since we have no HP inhouse.
2699 * core.c (get_core_registers): Look for two sections, ".reg"
2700 and ".reg2", and pass both to fetch_core_registers sequentially.
2702 Revise directory path yet again.
2704 * source.c (forget_cached_source_info): Not static any more.
2705 (init_source_path): New default source path is "$cdir:$cwd".
2706 (dir_command): Handle variable arguments ($cdir, $cwd).
2707 (source_info): Print "Compilation directory" rather than
2708 "Originally compiled in" to remind people of $cdir.
2709 (openp): If the path contains $cwd, use current directory.
2710 (open_source_file): If compilation directory is known, replace
2711 first $cdir in path with the compilation directory.
2712 (print_source_lines): Even if we can't print the lines, set the
2713 current symtab and line for future commands like "info source" or
2714 "breakpoint". Also, error message now contains the file name,
2715 line number, and file access error message.
2716 (_initialize_source): Fix help text to describe changes.
2717 * main.c (cd_command): Forget cached source info when we chdir.
2718 * utils.c (strstr): Add simple implementation.
2720 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
2722 * coffread.c (read_one_sym, init_linetable, init_stringtab):
2723 Byte-swap COFF symbol tables if necessary when reading them in.
2724 Use complain() to replace error message in one spot. Needs
2725 corresponding change in bfd/coff-code.h to make some symbol
2726 swapping routines non-static.
2728 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
2730 Merge changes from Eirik Fuller, for UTek.
2732 * defs.h (errno): Add declaration.
2733 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
2734 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
2735 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
2736 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
2737 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
2738 declarations of errno.
2740 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
2742 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
2743 <rpc/rpc.h> and <rpc/types.h>.
2745 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
2747 * i960-tdep.c (examine_prologue): Add new argument limit,
2748 which stops the scan at the end of the prologue, or at the PC.
2749 This fixes a problem where it walks down into the code for the
2750 user's statements if that code looks like function prologues.
2751 Mark Fox and I have been bouncing this code back and forth, making
2752 small changes to it. Callers changed to match.
2754 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
2756 Cleanup for gdb-3.94 release final:
2758 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
2759 the .c files from vx-share and nindy-share, from the various
2760 macros, since they are not found via ALLDEPFILES.
2761 (SFILES): Add tm-i960.h.
2762 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
2763 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
2765 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
2766 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
2768 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
2770 * am29k-tdep.c: Add contribution line.
2771 (examine_prologue): Cache information about function prologues in
2772 the misc-function-vector to avoid lots of references over the
2773 serial line while examining instructions.
2775 * core.c (core_close): New function made from cleanup_core.
2777 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
2778 remote-vx.c, remote.c, target.c, target.h,
2779 Update target_ops vector to add attach, close, and load entries.
2780 Use add_syms_addr_command, not add_file_addr_command, for
2781 add_file. Break out close routine from existing code.
2783 * dbxread.c (really_free_pendings): Don't free pending_blocks;
2784 they are in an obstack.
2785 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
2787 (define_symbol): Add symbol type parameter; change callers;
2788 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
2789 it to influence the symbol class on the i960.
2790 (define_symbol): Swap LOC_CONST's into target byte order.
2792 * exec.c (exec_close): New function.
2793 (exec_file_command): Call it.
2795 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
2796 Fix byte order of frame pointer.
2797 (read_var_value): Result of 0 if var's value can't be found,
2798 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
2799 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
2800 (locate_var_value): Use read_var_value and use its lazy address
2801 as the location of the var's value. Lint.
2803 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
2806 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
2807 obsolete Intel versions in favor of vxgdb versions.
2808 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
2809 code dealing with byte order of values, which Intel did in host byte
2810 order rather than gdb-4's target byte order.
2811 (i960_frame_chain_valid): Move to nindy-tdep.c.
2812 (examine_prologue, skip_prologue, frame_find_saved_regs,
2813 frame_args_address, leafproc_return, saved_pc_after_call,
2814 pop_frame): Add vxgdb versions from Mark Fox.
2815 (examine_prologue, frame_struct_result_address): Add code
2816 to deal with the saved value of G13 (struct return address
2818 (frame_args_address): Modify Mark's version to prefer the
2819 saved value over the current value in the topmost frame.
2820 Cache result in the frame info to avoid performance hair in
2822 (print_fault): Add gdb960 code for printing faults.
2823 (_initialize_i960): Actually call check_host.
2825 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
2826 add stub routines. FIXME, these currently just return zero!
2828 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
2829 (attach_command): Call target_attach, not target_open, now.
2831 * infrun.c (normal_stop): Make global, not static, for vx_attach.
2832 (child_attach): Rename from child_open.
2833 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
2834 don't confuse it with a zero step_resume_break_address.
2836 * inftarg.c (child_detach): Eliminate inferior_pid test.
2837 (child_files_info): Clean up message a bit.
2838 (child_ops): Use child_attach, not child_open, to attach.
2840 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
2841 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
2842 findvar.c to here, since it depends on the contents of the
2843 shadow_contents of breakpoints, but keep if #if 0 since it is
2846 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
2849 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
2850 (ptype_command, display_command): Eliminate have_inferior_p and
2851 have_core_file_p in favor of target_has_stack or
2852 target_has_execution.
2853 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
2854 code for actually finding the values of arguments, though we still
2855 keep track of the maximum stack offset for use in printing unnamed
2856 arguments. Handle missing FRAME_ARGS_ADDRESS.
2858 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
2859 (struct nindy_regs): Define registers passed to/from nindy.
2860 (nindy_fetch_registers, nindy_store-registers): Translate between
2861 nindy and GDB formats for the registers.
2862 (dcache_init): Statically allocate the cache, since it was being
2863 allocated by a malloc that was never freed anyway.
2864 (nindy_create_inferior): Error, not core dump, if no exec file.
2865 (nindy_before_main_loop): Use target_load, not target_add_file.
2867 * remote-vx.c (net_load): Specify large timeout for load
2868 requests. Allow user to break out with INTERRUPT.
2869 (net_break): Remove useless code, clean up. Change callers.
2870 (parse-args, skip_white_space, find_white_space): Clean up arg
2871 parsing to cope with quoted strings.
2872 (net_wait, net_quit): Never call error, just return status.
2873 (vx_read_register, vx_write_register): Cleanup status checking.
2874 #ifdef the code based on which CPU we are using (960 or 68k),
2875 FIXME, this should be completely general but it isn't yet.
2876 (vx_xfer_memory, vx_resume): Cleanup status checking.
2877 (vx_run_files_info): Improve message.
2878 (vx_load_command): Renamed from vx_add_file_command. Allow load
2880 (net_ptrace): Remove unused routine.
2881 (vx_wait): Adopt code from vxgdb960 to cope with broken
2882 connections to target machine and prompt to disconnect. Remove
2883 debug printouts. Map some EVENT_'s to SIGnals.
2884 (add_symbol_stub, vx_open): Print names of object files we found,
2885 and "ok" if we read their symbols OK. Clarify output in general.
2886 (vx_attach, vx_detach, vx_kill): Add these commands.
2887 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
2888 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
2889 "info files" output, and create_inferior, since we already have
2892 * stack.c (frame_info): Replace Frame_unknown with 0.
2893 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
2894 (return_command): Pop until the PC matches as well as the FP,
2895 so it works even if the FP is shared with another function,
2896 as in "frameless" or "leaf" procedures.
2898 * symfile.c (load_command): renamed from add_file_target_command.
2899 (add_syms_addr_command): renamed from add_file_addr_command.
2900 (add_syms_command): Stub to call target_add_syms.
2901 (_initialize_symfile): Change command names and descriptions,
2902 add-file => add-syms, and load from alias to its own command.
2904 * target.c (kill_or_be_killed, maybe_kill_then_attach,
2905 maybe_kill_then_create_inferior): Default for attempts to start
2906 a process, if one is already running, is to ask about killing
2907 it and retry if yes.
2908 (upstack_create_inferior): #if-0 it, strata obsolete it.
2909 (push_target, unpush_target, pop_target): to_close() a target
2910 before unstacking it.
2911 (target_info): Renamed from target_files_info.
2912 (_initialize_targets): Rename "i files" as "i target", accessible
2915 * target.h: Improve comments about the target_ vectored routines.
2917 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
2918 Convert commenting style to standard GNU style.
2919 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
2920 (SKIP_PROLOGUE): No longer a no-op.
2921 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
2922 (*_REGNUM): Sort register numbers.
2923 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
2924 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
2925 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
2926 are now 10 byte extendeds, not 8 byte doubles.
2927 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
2928 for nindy versus vxworks targets. FIXME, this should possibly go
2929 in the target vector.
2930 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
2931 frame_saved_regs and arg pointer with each frame.
2932 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
2933 (FRAME_ARGS_ADDRESS): Use cached result.
2934 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
2935 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
2936 (PRINT_RAMDON_SIGNAL): Call print_fault.
2937 (POP_FRAME): Now works.
2939 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
2940 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
2941 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
2942 (ADDITIONAL_OPTION_HANDLER): use target_load, not
2945 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
2946 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
2948 * valarith.c (value_subscripted_rvalue): Avoid handling
2949 floats and doubles specially; it gave alignment errors. Lint.
2951 * valops.c (value_of_variable, value_of_this): Error if unknown
2954 * valprint.c (print_floating): Bcopy rather than pointer-deref,
2955 to avoid alignment problems.
2956 (value_print): Handle unknown value address.
2957 (cplus_val_print): Two args are ignored; remove them. Change caller.
2958 (val_print): Use unpack_long rather than pointer-deref.
2961 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
2962 to avoid alignment problems.
2963 (value_being_returned): Error if return value unknown.
2964 (set_return_value): Add bogosity warning, FIXME. *
2966 * TODO: A woman's work is never done.
2968 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
2969 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
2970 Add ieee-float.o to OBS.
2971 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
2972 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
2973 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
2975 Changes to generalize the VxWorks RPC protocol slightly, to handle
2976 i960 as well as 68000.
2978 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
2979 * vx-share/reg.h: Produce i960 regs #ifdef I80960
2980 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
2981 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
2982 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
2983 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
2984 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
2985 so they will move in target byte order rather than network
2986 byte order (happens to be the same).
2988 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
2990 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
2992 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
2995 Add contribution lines to various files, showing where they
2998 * breakpoint.c (break_insn, check_break_insn_size,
2999 read_memory_nobpt): Remove to mem-break.c.
3001 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
3004 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
3005 entry has bad register number. This change is not
3006 tested in this release, FIXME.
3008 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
3011 * value.h: Force value's contents field to be aligned to hold
3012 at least a double or a long long (if supported). This avoids
3013 doing bcopy's in and out of the contents field.
3015 (step_1): Avoid coredump under obscure circumstances when we
3018 * symtab.h (misc_info): Add field to misc function vector for
3019 any kind of cached information the target code desires. AMD
3020 29000 uses this to avoid repeating examine_function_prologue's.
3022 * coffread.c: Lint. Remove static symfile, read_section_header.
3023 core.c (have_core_file_p): Lint: remove.
3024 expprint.c (print_subexp): Lint.
3025 infptrace.c, valops.c, valprint.c: lint.
3027 Roll in changes from vxgdb-5.0.1:
3029 * symtab.h: Comment byte order of each address class. Add
3030 LOC_LOCAL_ARG for frame-relative args (960).
3031 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
3032 symtab.c, symmisc.c: ditto.
3034 * infrun.c (init_wait_for_inferior): Clear stop_signal.
3036 * remote.c (remote_resume): Error if resume with a signal.
3038 * symfile.c (prim_record_misc_function): Clear misc_info.
3039 (fill_in_vptr_fieldno): Check stub type of arg.
3041 * valops.c (value_cast): Avoid looking up names of types whose
3042 name we don't know, to prevent coredump. Sun CC produces typedef
3043 rtx and the name of *rtx is zero...
3045 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3047 Roll in changes from final AMD 29000 port (Tiemann).
3049 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
3050 for ../include/a.out.encap.h. This might not work now that BFD
3051 is separately compiled. Instead, BFD support for encap will have
3052 to translate machine type 29k into the right COFF_MAGIC.
3054 * infcmd.c: Remove references to inferior_pid that aren't used
3055 in actual ptrace calls; use target_has_execution, etc.
3056 (have_inferior_p): Remove function.
3057 (program_info): Print target info rather than "process number";
3058 avoid gratuitous messages unless from_tty.
3059 (run_stack_dummy, finish_command): Set proceed_to_finish.
3060 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
3061 main.c: Lint. Lose have_inferior_p().
3062 inferior.h (have_inferior_p): Remove, lint.
3063 (proceed_to_finish): Add flag to ask that all regs be saved
3064 by normal_stop, for the few commands that need it, speeding up
3065 serial I/O. Add comments to stop_registers.
3067 * remote-eb.c: Remove newline from breakpoint message we grep
3068 for. Never time out when running the user program.
3072 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3074 Roll in changes from vxgdb-5.0.1:
3076 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
3077 symbol in its raw form, we are processing an unlinked ".o" file.
3078 See if the target environment has assigned it an address, using
3079 target_lookup_symbol (VxWorks does), and enter it into the symtab
3082 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
3083 68k versions for a simpler version that assumes zero FP at bottom.
3084 Fixes bug of truncated stack reports.
3086 * target.h (target_lookup_symbol): Define this routine's args
3087 and result, finally.
3089 * target.c (nosymbol): Default routine for target_lookup_symbol.
3090 (target_default): Default lookup_symbol and call_function too.
3091 (files_info): Only print has_all_memory warning if a non-dummy
3094 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
3095 vx_convert_from_virtual): If target does not have floating point,
3096 zero register "values", and avoid doing cross-net conversions.
3097 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
3098 (vx_open): Rearrange code that attaches to target and reads
3099 symbols for all loaded modules, to work if some of the modules
3100 are not accessible. Add symbol_stub() and add_symbol_stub()
3101 as callbacks from catch_errors(). Allow connect attempt to be
3102 interrupted painlessly with ^C (FIXME, there are still some bugs
3103 if the interrupt happens during symbol reading.). Print
3104 final message with puts_filtered, since symbol messages are
3109 * main.c (catch_errors): Only print errstring if non-null.
3110 (command_loop): Avoid an ioctl per command to test ISATTY.
3112 * remote-vx.c (net_load): make static; avoid sophomoric msg.
3113 (vx_xfer_memory): Return correct result!
3114 (vx_files_info): Indicate whether target has float or not.
3115 (vx_lookup_symbol): Complain, not error, if target gone.
3116 (vx_open): Print "Connected" msg before disabling immediate-quit.
3117 [FIXME: lookup_symbol and vx_open changes need testing.]
3119 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
3120 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
3121 contributor lines and update copyrights to 1991.
3123 Changes from an attempted H-PUX host port:
3125 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
3126 defines PT_ATTACH and PT_DETACH but not PT_KILL.
3127 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
3128 * remote-vx.c: include <sys/time.h> for HPUX.
3129 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
3130 "core_file_command" routine to BFD regime. May not work yet.
3132 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
3134 * xgdb.c: Replace X10 version with some VJ version.
3135 (FIXME: Its copyright assignment is not on record.)
3136 * xgdb.c: Update include files to X11R4 (Xaw crud).
3137 (xgdb_display_source, create_text_widget): fix call to
3138 get_filename_and_charpos. Rewack source window stuff for X11R4
3139 (gleaned from include files, and "nm's" of binary libraries, since
3140 I had no doc available).
3141 (append_selection, append_selection_word): Disable with FIXME
3142 since R4 changed interface here.
3143 (create_buttons): Add back the old set of buttons.
3144 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
3146 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
3147 Roll VERSION to 3.94 (not yet final though).
3149 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3151 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
3152 obstack_int_grow, obstack_int_grow_fast): Eliminate
3153 cast on left of assignment, which gives MIPS cc fits and is
3156 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
3157 F_ALIAS. Use printf, not fprintf, when not passing a file
3159 (compare_opcodes): Check that identical instructions have
3160 identical opcodes, complain otherwise.
3162 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
3163 was reported by Roland McGrath.
3164 (unimp): Only match if exactly zero instruction. (Roland)
3165 (branches and traps): Generate all variations of these
3166 instructions with macros, based on a single call that defines
3167 each condition name and its binary representation.
3168 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
3170 * valprint.c (val_print_fields): Take, and use, format parameter.
3171 This means that "p/x struct" again prints the elements in the
3172 desired format. Changed callers.
3174 * stack.c (frame_info): Use filtered output, and indicate wrap
3175 points. Remove kludgy formatting designed to avoid line wrap.
3177 * utils.c (wrap_here): If the line is already full (because
3178 we had printed a long indent or long wrapped string), do an
3179 immediate newline-and-indent.
3181 * m68k-pinsn.c (print_insn_arg): Bugfix from
3182 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
3183 instruction is incorrectly disassembled as bkpt #8.
3185 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
3186 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
3187 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
3188 and then will dump core (sometimes). I traced it back to an
3189 uninitialized symfile_name in psymtab_to_symtab.
3190 (const_vol_complaint): Add quotes to message.
3191 (define_symbol): Only believe line number if gcc_compiled.
3192 Avoid allocating symbol if we will not return it.
3194 Add target strata support so that newly established targets go
3195 into their right place in the target stack (e.g. a new exec file
3196 doesn't wipe out the ability to access the running process).
3198 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
3199 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
3200 and initialize it properly in all the targets.
3202 * target.h: Document strata. Change return type of push_target.
3204 * target.c (nomemory): new function for dummy memory access.
3205 (tcomplain): Rename complain, now also used in symfile.c.
3206 (push_target): Push targets within strata. New return value shows
3207 whether new target is on top of stack or not. Always keep dummy
3209 (target_files_info): Ignore dummy target.
3211 * core.c (core_open): Warn user, and skip accessing file, if the
3212 core target is not the topmost target in the stack.
3213 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
3216 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
3217 target_ops, it doesn't belong there since we have no regs there.
3218 Change name of target from machine => memory to clarify.
3220 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
3222 * Freeze version 3.93 for release.
3224 * Makefile.dist: Handle vx-share and nindy-share subdirs
3225 properly when building gdb.tar.Z.
3227 * symtab.c: lint; add no_symtab_msg to consolidate the messages
3228 printed in various places, so I could change just one copy.
3230 * dbxread.c, coffread.c: Change references to bfd->iostream
3231 to cast to FILE *, now that BFD avoids needing types defined
3232 in other header files.
3234 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3236 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
3237 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
3238 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
3239 (actually gcc -Wall).
3241 * dbxread.c: Remove first_global_sym, last_global_sym, since
3242 they are never referenced.
3244 * defs.h (baud_rate): Declare.
3245 main.c: Define it, and add the -b option to set it.
3247 * gdb-int.texinfo: Add text on how to define a new host or target
3248 architecture, prompted by Per Bothner's questions about MIPS
3251 * gdb.texinfo: Document "complaints". Change doc of -q since
3252 gdb no longer prints the copyright and blurb if you specify a file
3253 name to be debugged (just like Emacs). Add doc for Nindy-specific
3254 command line flags for specifying target serial port and such.
3255 Update copyright to 1991.
3257 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
3258 has taken over for us the job of ripping up executable files. The
3259 crud caused Per Bothner's port to not compile.
3261 * infrun.c (normal_stop): Avoid printing "Program exited
3262 normally" if we are in batch mode. This allows a GDB which
3263 executes a program on a target system, to behave like a Unix
3264 command (input from stdin, output to stdout, no extraneous
3267 * main.c (main): Allow additional machine-dependent command line
3268 options to be specified with the ADDITIONAL_OPTIONS,
3269 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
3270 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
3271 processing to occur just before the main loop with
3272 BEFORE_MAIN_LOOP_HOOK.
3273 (main): If a "core file" argument is specified, and it is not a
3274 core file, try it as a process ID to attach.
3275 (symbol_completion_function): Attempt to cope with
3276 "show screen-" TAB, not very successfully. This needs more work,
3278 (batch_file): New function, returns whether we are reading
3279 commands from an interactive tty on stdin, or from somewhere else.
3280 Called by normal_stop since it doesn't get from_tty passed down
3281 to it like many commands do.
3283 * remote-nindy.c: Handle command line options for nindy
3285 (nindy_before_main_loop): Prompt user for tty name if they
3286 don't specify it before getting to the interactive command loop.
3288 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
3289 and -r command line options. Also add hook before main loop
3290 to make it easy to specify a tty.
3292 * TODO: More things to do, one done.
3294 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
3296 * dbxread.c: Make complaint() calls pass pointer, not struct.
3297 Add complaints about badly formatted C++ type information
3298 (const/volatile indicator, and parse errors resulting in
3299 error_type). Fix C++ virtual member fn comment.
3300 (read_struct_type): Avoid bumping pointer if we got a parse
3301 error; this prevents our walking beyond the end of a string.
3302 Terminate loop on null char as well as semicolon.
3303 (process_one_symbol): Fix the LBRAC fix so that it uses the
3304 last previous SLINE, FUN, or SO record's PC address. C++ debug
3305 symbols did not have SLINE records in a useful order compared
3306 to the LBRAC records.
3307 (define_symbol): Handle "catch" records.
3309 * symtab.c (check_stub_type): Added new complain
3310 `stub_noname_complain' and added a consistency check to
3311 keep the debugger from crashing when finishing from an
3312 exception frame. A real fix will be needed later.
3314 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
3316 * infcmd.c (attach_command): Make global.
3318 * Makefile.dist (REMOTE_OBS): Make these compile by default,
3319 but make them easy to comment out. Perhaps later they should
3320 be enabled by what CPU you configure for? FIXME.
3321 (VERSION): Roll to 3.93.
3322 (pinsn.o): Remove rule for obsolete file.
3323 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
3325 Run down a problem that manifested by printing the wrong function
3326 name in stack traces of read_ofile_symtab. Turned out that the
3327 problem was the SunOS 4.1.1 (and previous) C compiler outputs
3328 the LBRAC symbol with an address in the *data* segment, which
3329 blew our binary search through the blocks.
3331 * dbxread.c: Use the complain() facility consistently to bitch
3332 about problems in the symbol file we are reading.
3333 (finish_block): Add code to check the nesting of the blocks;
3334 complain and Procrust them to fit if wrong.
3335 (make_blockvector): Check the order of the blocks, complain
3336 [but don't cope] if wrong.
3337 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
3338 symbols to be sure their PC value is greater than the last SLINE
3339 (line number) symbol we've seen, complaining and adopting the
3340 SLINE PC value if wrong.
3342 * symfile.h (struct complaint, complaint_root, complain,
3343 clear_complaints): Add.
3344 * symfile.c (complain, complaint_root, clear_complaints): Add
3345 facility to deal with non-fatal complaints and to regularize their
3347 (symbol_file_add): Clear complaint counters to allow new complaints.
3348 (initialize_symfile): Add 'set complaints' and 'show complaints'.
3350 * dbxread.c (dbx_symfile_read): Remember the address and size
3351 of the string table for the main symbol file, so we won't read it
3353 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
3354 to avoid reading the string table yet again. Lint.
3355 (throughout): Improve filtered output, including word wrap.
3356 (read_range_type): Improve Bothner's fix to handle other types too.
3358 * utils.c: Improve line wrap implementation. Handle unlimited
3359 width by making chars_per_line unsigned.
3360 (puts_filtered): New, easy, function.
3362 * defs.h (puts_filtered): add.
3364 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
3365 call the identical sort_symtab_syms() in symfile.c instead.
3367 * expread.y: Suggest the `file' command rather than `symbol-file'.
3369 * command.h (enum var_types): Add zinteger for seroable
3371 * command.c (do_setshow_command): Handle var_zinteger. Restructure
3372 nested if's into a switch.
3374 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
3375 we did not stop because of a breakpoint (it must have been for
3376 some other reason, like a "stepi"), so don't print anything.
3378 * symtab.c: Include <sys/types.h> all the time. Now that BFD
3379 doesn't include <sys/types.h>, old SunOS's require it for
3382 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
3384 A test port of gdb-3.92.6 to the Sony NEWS.
3387 Don't normally link in remote- or vx stuff.
3388 Some of it doesn't compile, and it wastes space for 99% of the users.
3389 Remove reference to no-longer-used HAVE_VPRINTF.
3390 Fixed BFD_DEP typo to BFD_DIR.
3392 Fix cast in arg to bfd_h_getlong.
3393 Make char *prefix be const.
3394 Fix how certain range types are mapped into builtin unsigned int types.
3396 Remove 2 #includes. They cause errors (on Sony, at least),
3397 and aren't needed (they wern't in earlier versions).
3399 print_address_symbolic should never demangle labels
3400 (since it prints *assembler-level* labels).
3402 [This was superseded by the change to printcmd below.]
3405 Add some "volatile" return types to avoid warnings.
3406 If MISSING_VPRINTF add vprintf function and not just macro
3407 (since vprintf is used in printcmd.c).
3409 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
3410 (The latter isn't grokked by some PCC-based compilers.)
3412 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
3414 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
3415 * nindy-share/coffstrip.c
3416 Added some forward declarations (otherwise, gcc complains
3417 about implicit extern redefined as static).
3419 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
3421 Changes inspired by Per Bothner:
3422 * printcmd.c (print_address_symbolic): Take additional parameter
3423 specifying whether to demangle.
3424 (print_address): Pass in asm_demangle to control demangling.
3425 (print_address_demangle): New fn, takes explicit arg to control
3427 * utils.c: Add new vars demangle and asm_demangle, and let them
3429 (fputs_demangled): If !demangle, just print the argument.
3430 (fprint_symbol): If !demangle, just print raw symbol.
3431 * valprint.c (val_print): Call print_address_demangle rather than
3432 print_address, to cause demangling to depend on the global
3433 rather than assembler-level demangling setting.
3434 * WHATS.NEW, gdb.texinfo: Document.
3436 * main.c (show_command): Show all settings if no arg.
3437 (initialize_main): Make "info set" the same as naked "show".
3438 * command.c (cmd_show_list): Handle prefix commands in the
3439 list, and print the name of the setting as well as its English
3440 description and value.
3442 Allow gdb functions to specify where a line should wrap if it
3443 exceeds the size of a terminal line. Use it to make the output
3445 * utils.c (set_screen_width_command): New fn, mallocs a buffer
3446 of the right size when screen width changes.
3447 (set_screensize_command, screensize_info): Remove #if 0'd fns.
3448 (wrap_here): New fn, indicates a point in the output where we
3449 should wrap the line rather than just letting it overflow at a
3451 (fputs_filtered): Implement wrapping.
3452 (n_spaces): New fn, returns a pointer to N spaces.
3453 (print_spaces_filtered): Use n_spaces.
3454 * defs.h (n_spaces): Declare.
3455 * stack.c (print_frame_info): Wrap with 4-space indent after
3456 fn name and before filename and line number.
3457 * printcmd.c (print_frame_args): Wrap with 4-space indent
3458 before each argument name is printed.
3459 * valprint.c (value_print): Wrap with no indentation before
3461 (val_print_fields): Wrap with indentation relative to nesting
3462 level before each field name.
3463 (val_print): Wrap with nesting indentation before array elements.
3464 * command.c (do_setshow_command): Avoid extra newlines,
3465 wrap with 4-space indent around values printed, end with period.
3466 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
3468 * breakpoint.c (breakpoint_1): Implement addressprint for
3469 "info breakpoints" display. Change file name and line number
3470 format to " at file:nnn" rather than " (file line nnn)".
3471 * gdb.texinfo: Document.
3474 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3476 Frozen for gdb-3.92.6 release.
3478 README, WHATS.NEW: Update for 3.92.6 release.
3480 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
3481 coffread.o from configs since it is now built by default.
3482 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
3483 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
3484 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
3485 from configs since it is now built by default.
3487 Makefile.dist: Update for release 3.92.6. Handle files that
3488 have been moved to ../include, ../getopt, or ../bfd. Add
3489 saber.suppress and tests directory. Add config.status to
3490 the release (it will say "none").
3492 coredep.c: Minor formatting fixes.
3494 These changes were made in early December but only checked in now:
3495 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
3496 nindy-share/nindy.c: lint
3497 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
3498 register values coming back from the target; we store values
3499 in target byte order everywhere.
3501 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
3503 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
3505 * valprint.c (cplus_val_print, val_print_fields): New functions,
3506 which print C++ objects. They conspire to avoid printing a
3507 virtual base class more than once, following all the twists and
3508 turns of C++ virtual base rules.
3509 (val_print): Call the above rather than do it by hand.
3511 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
3512 symbol file, not for added files like shared libs. This really
3513 needs to be generalized to a timestamp per file.
3515 * core.c (cleanup_core): Avoid coredump if no core file.
3517 * config.gdb: Accept -host or -target in place of +host or
3520 * coffread.c (find_linenos): Avoid desupported BFD interface
3521 to line numbers. We still read them manually rather than using
3522 BFD's "generic" features.
3524 * gdbrc.tex, threecol.tex: Add GDB reference card and its
3526 Makefile.dist: Add refcard to OTHERS list for creating tar files.
3528 * Makefile.dist: Eliminate use of $< in explicit targets.
3530 * readline/Makefile: Use $< rather than $*.c, which does not
3531 include the VPATH in GNU Make.
3533 * tconfig/i960-bout, tconfig/i960-coff: These are identical
3534 copies of tconfig/i960, added for global configuration
3535 compatability. All i960 versions can read both coff and b.out.
3537 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
3538 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
3541 * TODO: Think of more things to do.
3543 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
3545 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
3546 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
3547 64-bit float conversion.
3549 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
3550 equivalent to sun?os4 so global config works.
3552 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
3554 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
3556 * main.c: Only declare linesize once; declare pagesize not at
3557 all, since it is never used.
3558 (main): Clear newly allocated line before it is used.
3560 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
3562 Further stabilization for the Intel 960.
3564 * Makefile.dist: Parameterize the location of the "include"
3565 and "bfd" directories, as well as "getopt". Add symfile.c.
3566 Link in both dbxread and coffread. Fix up "make depend" to
3567 rewack the locations of include, bfd, and getopt in its output.
3569 * README: Document moving include files, improve some of
3572 * coffread.c: Move common code out to symfile.c. Change
3573 symbol_file_command style interface to use new *_symfile_init
3574 and *_symfile_read interface under BFD. Use BFD internal
3575 info to locate line table, symbols, etc.
3577 * core.c (core_fetch_registers): Rename to get_core_registers
3578 to avoid confusion with fetch_core_registers.
3579 (register_addr): Move to coredep.c, which is already machine
3580 dependent. This leaves core.c pretty clean of dependencies.
3582 * coredep.c (register_addr): Accept this routine from core.c.
3584 * dbxread.c: Move common code (with coffread.c, etc) into new
3585 symfile.c. Each psymtab now contains a pointer to the
3586 format-dependent function that knows how to read it in. Make
3588 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
3589 (process_one_symbol): Add code to complain about a "compiler bug
3590 we muzzle here", if we actually see it.
3592 * eval.c (evaluate_subexp): Insert missing "break" statements
3593 in code that determines whether a variable is an lvalue in
3594 memory, register, or whatever. I detected this via a compiler
3595 bug in which it *almost* mashed out the whole switch statement.
3597 * gdb-int.texinfo: Add minor sections on configuring gdb for
3598 release, and about the README file.
3600 * infcmd.c (registers_info): Fix formatting somewhat. Still
3601 not as pretty as before, but it handles byte swapping.
3603 * remote-nindy.c: If data cache routines are interrupted while
3604 waiting for the remote end, be sure that any uninitialized cache
3605 blocks are on the free list, not on the valid list!
3607 * symfile.h: Flesh out this header file with all the various
3608 routines and variables that have been merged in from dbxread.c
3609 coffread.c, and symtab.c to symfile.c.
3611 * symfile.c: New file, containing code common to dbxread.c,
3612 coffread.c, and some code from symtab.c. All generic code for
3613 reading symbol files should be in here now.
3614 (unrecord_misc_function): Remove unused function.
3616 * symtab.h: Remove file-reading things to symfile.h.
3618 * symtab.c: Remove file-reading things to symfile.c.
3620 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
3621 to decode i960 fault types.
3623 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
3624 target.c: Change type of the "resume" function from int to void,
3625 since its result was never used.
3627 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
3629 * main.c: Replace "stupid" with "caution"; you now "set caution
3632 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
3634 * infcmd.c (do_registers_info): Call val_print to deal with the
3635 byte order of the registers being printed. FIXME, this makes
3636 the formatting of the output uglier.
3638 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
3639 defined, call it for signals the debugger doesn't itself use.
3640 The i960 uses this for more detailed fault information.
3642 * remote.c (remote_open): If arg is null, print help rather than
3645 * sparc-xdep.c (register_valid): Avoid declaring size, since
3646 various modules will think of various sizes depending on the
3647 architecture of their tm-file. FIXME, we need protection against
3648 actually entering one of those modules, which would clobber
3649 storage if not for the target architecture compiled into gdb.
3651 * stack.c (up_command, down_command): Always print the frame
3653 (up_silently_command, down_silently_command): New commands
3656 * i960-pinsn.c (reg), i960-tdep.c: Lint.
3658 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
3659 more parameters than it used to.
3661 * findvar.c (registers): Increase slop to 256 bytes, which should
3662 protect us against even most RISC machines with large register
3664 (locate_var_value): Move declaration inside related ifdef.
3666 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
3667 throughout, to avoid throwing away buffered input from the board.
3668 (nindy_wait): Supply_register takes addr_of_value, not value.
3669 (i960_print_fault): Renamed from i80960_fault.
3670 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
3671 (nindy_store_registers): Avoid regs_changed stuff, just stuff
3673 (nindy_create_inferior): Don't bother to write PC_REGNUM since
3674 we can set the PC in the call to proceed(). Unpush nindy_ops
3675 before pushing it on top, to avoid message to user. Eliminate
3676 commentary from Unix machines that just misleads here.
3677 (reset_command): Fix error message to suggest target command.
3679 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
3681 Release 3.92.5 as frozen.
3683 Stabilize the merged release...with help from lint, Saber C,
3686 Everywhere: Add include files needed to declare return types
3687 of functions called.
3689 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
3691 * breakpoint.h: Add undeclared breakpoint functions, and some
3692 functions for display handling since I couldn't think of a better
3695 * breakpoint.c (insert_breakpoints): Make code for disabling
3696 shared library bkpts more likely to work. It's used when we
3697 rerun a program and stop before the shared library has been
3699 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
3700 cast from pointer, so it squeezes through catch_errors.
3701 (bpstat_stop_status): Fix logic broken some time ago. We now
3702 always create a bpstat if the stop address matches a breakpoint,
3703 even if we don't stop there -- just like the old code used to do
3704 before I got my fingers into it (sigh).
3705 (breakpoint_1): Print "ignore count" after "stop only if"
3706 condition, since that's how it actually works.
3707 (mention): Handle watchpoints as well as breakpoints.
3708 (watch_command): use set_raw_breakpoint and mention to do most
3709 of the work (and initialize all the fields!). Only pass one
3710 arg to parse_c_expression, since that's all it takes.
3712 * command.c (not_just_help_class_command): Rename arg to args
3713 since we ignore "unused argument" warnings on vars named "args".
3714 inflow.c (child_terminal_info): ditto.
3715 infptrace.c (kill_inferior): ditto
3716 main.c (catch_errors, version_info, quit_command, pwd_command,
3717 source_command, dump_me_command, editing_info,
3718 set_history_size_command, set_history, show_history,
3720 stack.c (locals_info): ditto
3721 target.c (target_files_info): ditto
3722 valprint.c (set_input_radix, set_output_radix): ditto
3724 * core.c: Remove old variables for handling core and exec file
3725 sections (data_start, data_end, stack_start, stack_end,
3726 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
3727 text_end, exec_data_start, exec_data_end, text_offset,
3728 exec_data_offset, data_offset, stack_offset). They're
3729 superseded the more general build_section_table and
3731 (get_exec_file): Mention the `file' command.
3732 (read_memory_check): Rename to memory_error, and only call it
3733 in the case of an actual error.
3734 (read_memory, write_memory): call memory_error.
3735 (core_fetch_registers): Register section name is ".reg".
3737 coredep.c: Remove a bunch of crud now that all this file does
3738 is pull the registers out of a core file.
3739 (fetch_core_registers): Rewrite to actually work, I hope.
3741 dbxread.c: Use a.out.gnu.h, not system a.out, now.
3742 Replace index() with strchr(). Remove all the pre-BFD macro
3743 definitions for accessing the symbol file.
3744 (struct dbx_symfile_info): Encapsulate the information that
3745 dbx_symfile_init needs to pass to dbx_symfile_read in this
3748 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
3749 dbx_symfile_discard): Rearrange symbol file reading to divide
3750 the format-specific part from the format-independent part,
3751 leaving the format-independent part such as file name expansion
3752 and opening in symtab.c. This replaces
3753 partial_symbol_file_open and partial_symbol_file_read.
3754 Symbol_file_read, add_file, add_file_target_command,
3755 add_file_addr_command move to symtab.c. Pass an explicit
3756 "mainline" flag for when reading the main symbol table, rather
3757 than relying on the offset address to be zero or nonzero.
3759 (dbx_symfile_read): Don't allow void *'s to be printed as
3761 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
3762 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
3763 macro" debug version really work.
3764 (read_dbx_symtab): Remove unref'd parameter inclink.
3765 Avoid swapping N_SLINE symbols, for speed.
3766 Merge N_TEXT!N_EXT case with the other external symbol
3767 definitions' case. Add comments.
3768 (start_psymtab): Allocate the symfile name in the psymtab on
3769 the psymbol_obstack, rather than using the caller's storage.
3770 (end_psymtab): Only allocate a dependencies list if there are
3772 (psymtab_to_symtab_2): Use BFD when reopening file to read
3773 its symbols for real.
3774 (read_struct_type): Add FIXME comments where it needs work
3776 (read_huge_number): Add FIXME about overflows.
3777 (read_range_type): Add FIXME about comparing a long to 1<<32.
3779 * coffread.c: Minor changes to move things closer to the new
3780 regime with symtab.c and dbxread.c Major work is still needed
3783 * exec.c (exec_file_command): Remove old variables (see core.c
3785 (xfer_memory): If memory transfer is right at the end of a
3786 section, don't lose.
3788 * findvar.c (get_saved_register): If value is in a real
3789 register, LVAL is lval_register, not lval_memory.
3791 frame.h: Declare print_sel_frame and record_selected_frame.
3793 gdb-int.texinfo: New file, for GDB internals documentation.
3794 Very simple, unformatted doc of cleanups is there for now.
3796 gdbcore.h: Remove obsolete variables that described a.out
3797 section addresses and offsets. (See core.c above.)
3798 Declare fetch_core_registers and registers_fetched.
3800 getopt.c: Declare char *alloca(); even on SPARC.
3802 infcmd.c (run_command): Call target_kill rather than
3804 (step_command, next_command, stepi_command, nexti_command):
3805 Declare from_tty parameter even though we don't use it.
3806 (run_stack_dummy): argument BUFFER is a char array, not
3807 a pointer to REGISTER_TYPE.
3808 (finish_command): using_struct_return needed a value *,
3809 not a struct symbol *.
3811 * infptrace.c (child_xfer_memory): To avoid dependency on
3812 where sections are in memory, try PT_WRITE_D and if that fails,
3813 try PT_WRITE_I. Most Unixes don't care which you use.
3815 * infrun.c (step_resume_break_shadow): Change to array to
3816 match other breakpoint shadow storage.
3817 (clear_proceed_status): Pass address of bpstat to
3818 bpstat_clear, not the bpstat itself.
3819 (child_create_inferior): FIXME comment about if the child
3821 (start_inferior): Remove old function.
3822 (child_open): Use target_kill rather than kill_inferior.
3823 (wait_for_inferior): Ditto.
3824 (insert_step_breakpoint, remote_step_breakpoint): Use
3825 new step_resume_break_shadow.
3827 * inftarg.c (child_wait): If all child processes die,
3828 pretend that the one being waited for exited with signal 42.
3830 * main.c (command_line_input): When scanning for comments,
3831 don't coredump on unclosed quotes.
3832 (quit_command): Use target_kill rther than kill_inferior.
3833 (_initialize_main): Rename class_user from "user" to
3836 * printcmd.c (print_command_1): Initialize "fmt" if no format
3837 is specified by the user.
3838 (print_frame_args): Only add to args_printed if we are
3839 actually fetching args from the stack (avoiding undefined
3841 (_initialize_printcmd): Remove bogus \{ from string.
3843 * remote-eb.c (eb_open): Avoid coredump on no argument.
3845 * remote-nindy.c: Bring out of Intel environment into new
3846 target environment. Remove all conditional compilation on
3847 I80960. Massive hacking throughout.
3848 (nindy_xfer_inferior_memory): New routine stolen from
3850 (nindy_create_inferior): New routine pieced together, probably
3851 not quite working yet.
3852 (nindy_ops): New target_ops struct for nindy.
3854 * remote-vx.c: Use write_memory rather than target_write_memory
3855 to get error checking.
3856 (vx_add_file_command, vx_open): Use symbol_file_add rather than
3858 (vx_create_inferior): Use target_terminal_ours...
3860 * signame.c (_initialize_signame): Always initialize, since
3861 we need the table for things other than psignal.
3863 * solib.c (solib_add): Use symbol_file_add, not add_file.
3864 (solib_address): Return boolean result rather than struct
3865 pointer which nobody else knows the type of.
3867 * sparc-tdep.c, valops.c: Use write_memory rather than
3868 target_write_memory, to get error checking.
3870 * stack.c (locals_info, catch_info, args_info,
3871 get_selected_block, frame_command, up_command): Use
3872 target_has_stack, rather than have_inferior_p or
3875 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
3877 * symfile.h: New file, defining the interface between the
3878 generic and object-file-specific symbol reading code.
3880 * symtab.c: Move generic symbol-reading interface to symtab.c,
3881 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
3882 table to map BFD targets to symbol-reading modules in GDB.
3883 Change index to strchr.
3884 (lookup_struct_elt_type): Use error() rather than hand-made
3885 simulations thereof.
3886 (lookup_partial_symbol): Speedup slightly when length == 0.
3887 (symbol_file_add): New function.
3888 (symbol_file_command): Call it.
3889 (symfile_open, symfile_init): New function.
3890 (add_file_target_command, add_file_addr_command): moved from
3893 * target.c (target_command): use target_kill.
3895 * target.h (target_files_info): Don't declare, never called
3898 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
3899 files to determine stack end address.
3901 * valarith.c (value_x_binop, value_x_unop): Change error message
3902 to be more useful. Pass proper argument to value_struct_elt.
3904 * valops.c (value_assign): FIXME comment that long long
3905 bitfields will break here.
3907 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
3908 Update `make saber_gdb' to work better.
3910 * TODO: A woman's work is never done.
3912 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
3913 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
3914 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,

3916 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
3917 valops.c, valprint.c, exec.c: Lint.
3920 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
3922 Continuing Intel 960 port merge of GDB.
3924 * Makefile.dist: Merge i960 "nindy-share" files. Rename
3925 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
3926 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
3927 Wack over "make depend" so it handles files in subdirectories
3928 vx-share, nindy-share, bfd, and in the current directory.
3930 * blockframe.c (get_prev_frame_info): Remove fatal error
3931 if stack not defined.
3933 * core.c (core_open, core_detach): New functions that handle
3934 the old "core-file" command as "target core" and "detach" instead.
3935 (core_file_command): Call them.
3936 (core_xfer_memory): Use common routine xfer_memory.
3938 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
3939 dbxread now uses bfd for everything but symbol reading itself.
3940 BFD internals are used to drag out the relevant file offsets.
3941 (partial_symbol_file_open): Change args all around for BFD.
3943 * symtab.c: Rename "value" to "val" everywhere, so we can
3945 (symbol_file_command): New command, moved from dbxread.c
3946 and coffread.c. It uses BFD to read the file, then vectors
3947 based on its type, to dbx or coff symbol readers.
3948 * symtab.h: Extern a few vars for symbol_file_command.
3950 * target.h: Breakpoint takes a char * save area, not a char **.
3952 * valprint.c (val_print): When unpacking bitfields, offset
3953 the address in gdb of the value, if it is declared with a shorter
3954 type. Remove the last "runtime kludge test" of host byte order.
3956 * utils.c: Remove old my_bfd_read routine.
3958 * stack.c (frame_info): Use target_has_stack. Print program counter
3959 register's actual name rather than "pc", since it's called the
3960 "ip" (instruction pointer) on the i960 (sigh).
3962 * target.c (target_command): Add command for selecting a target
3963 type and calling its open routine. This is used for initiating
3964 communication with a particular target, in a generic way.
3966 * tm-i960.h: Update for modern gdb. Remove semicolons from
3967 various macros. Handle reading struct return convention, and
3968 error-out attempts to return structs with the "return" command.
3969 Be sure gdb doesn't think we know how to call functions in the
3972 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
3973 to i960_xxx in lower case.
3974 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
3975 not being defined yet.
3977 * remote.c (remote_open): Call start_remote to initialize
3978 wait_for_inferior during open.
3979 (remote_xfer_inferior_memory): Return length written rather
3982 * remote-vx.c (target_command -> vx_open): Use new generic
3984 * remote-eb.c, inftarg.c, exec.c: ditto.
3986 * infrun.c: Fix comments.
3987 (attach_program -> child_open): Use new generic target command.
3988 (wait_for_inferior): Clear saved register values before target_wait,
3989 so target_wait can set some of them if convenient.
3991 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
3992 Return success indicator, not void.
3993 (child_xfer_memory): Avoid fetching initial word if we'll
3994 overwrite it anyway.
3996 * infcmd.c (attach_command): Use new generic target open routine.
3997 (_initialize_infcmd): Update doc on attach and detach commands.
3998 (do_registers_info): Merge in a byte-order problem as a FIXME
4001 * findvar.c (find_saved_register): Avoid problem in current frame.
4002 (read_relative_register): Ditto.
4003 (write_register): Convert byte order on the way out.
4005 * exec.c (file_command): Add.
4006 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
4007 (xfer_memory): Common function between core_xfer_memory and
4009 (exec_xfer_memory): Use it.
4011 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
4013 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
4014 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
4015 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
4017 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
4019 Merge Intel 960 port of gdb, continuing...
4021 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
4022 symbol_file_command): Pass from_tty arg to hush 'em up.
4024 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
4025 Add magic numbers for 960 COFF format.
4027 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
4029 Merge Intel 960 port of gdb, from Intel "1.2" release.
4031 CHANGE_LOG entries from their port, which was based on
4034 Thu Sep 6 11:02:22 PDT 1990
4035 Remove temp file if download is interrupted.
4037 Wed Aug 1 09:08:33 PDT 1990
4038 Now uses binary protocol to talk to NINDY.
4039 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
4040 Times out after 5 seconds when trying to talk to NINDY.
4042 Tue May 29 12:54:49 PDT 1990
4043 Added variable baud rate (-b switch).
4044 Source code reorganization.
4046 Thu Apr 26 11:09:55 PDT 1990
4047 More cleanup of batch mode; specifically, execute "-s", "-e", and
4048 "-se" switches as soon as they are encountered on the invocation line.
4050 Fri Apr 20 13:47:15 PDT 1990
4053 Thu Apr 19 09:54:28 PDT 1990
4054 Add 'reset' command.
4056 Wed Apr 18 09:48:07 PDT 1990
4057 After opening remote tty, wait for 1 second to go by without input
4058 from it before trying to talk to NINDY (fixes problems with the
4059 Heurikon HK80/V960E).
4061 Mon Apr 4 16:33:05 PDT 1990
4062 Some output was not being suppressed in 'batch' mode.
4064 Thu Mar 22 15:31:11 PST 1990
4065 Ask user if old symbol table should be deleted when new file is
4068 Allow user to run a program downloaded before gdb960 was brought up.
4070 Correct "exec-file" help message for i80960 context.
4072 Correct bug in calculating user space address: could occasionally
4073 corrupt user program.
4075 Make sure to zero low-order bits in rip's because of bug in 960CA
4076 A-step part: could cause operation faults when "next"ing across
4079 Correct bug that made it impossible to get source line numbers for
4080 code loaded at addresses higher than 0x7fffffff.
4082 Wed Jan 10 12:43:22 PST 1990
4083 Open remote tty for exclusive use.
4085 Fri Jan 5 12:14:42 PST 1990
4086 Correct disassembly (CA manual was right after all):
4087 opcode for sysctl is 0x659
4089 Mon Oct 23 12:03:04 PDT 1989
4090 Use G960BASE and G960BIN environment variables to find 'sx' utility.
4092 Mon Oct 16 14:15:09 PDT 1989
4093 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
4095 Mon Oct 2 15:56:31 PDT 1989
4097 Added 960CA disassembly support.
4099 To simplify maintenance:
4100 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
4102 - eliminated opcode.h: incorporates tables into i960-pinsn.c
4103 - moved 960-specific routines from i960-pinsn.c to i960-md.c
4104 - made disassembly interface identical to that in gdmp960.
4108 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
4110 * target.h: Allow targets to stack. Add target_has_memory,
4111 _registers, etc. Restructure memory access and "info files"
4112 to walk the target stack.
4113 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
4114 target.c: Change tables to match target.h.
4115 * inflow.c (child_mourn_inferior): pop child_ops.
4116 (generic_mourn_inferior): Use new has_stack flag.
4117 * infptrace.c (child_xfer_memory): New memory regime.
4118 * inftarg.c (child_files_info): New "info files" regime.
4119 * remote-eb.c: New memory regime, new info files.
4120 * remote-vx.c: New memory regime, new info files. Now use
4121 separate targets for VxWorks attachment to machine, and
4122 actually running a process under VxWorks, since one has
4123 stack & execution & regs and the other doesn't.
4124 * remote.c: New memory regime, new info files.
4125 * sparc-xdep.c (fetch_core-registers): New memory regime.
4126 * target.c: New routines and support for stacked targets,
4127 new memory regime, new info files regime.
4130 Generalize section handling for an arbitrary number of sections,
4131 including use of the new BFD (binary file) library.
4132 * gdbcore.h: Add struct section_table.
4133 * exec.c (build_section_table): Iterate all sections and
4134 record what gdb needs to know about them.
4135 (exec_command): Use it.
4136 (exec_xfer_memory): Use the table.
4137 (exec_files_info): Print the table.
4138 * core.c (core_file_command, core_xfer_memory, core_files_info):
4140 * source.c (find_source_lines): Use bfd_get_mtime.
4141 * dbxread.c: Quick changes to make it compile with new BFD.
4142 * utils.c (error): Avoid using bfd_error in generic routines.
4144 * core.c (core_fetch_registers): Get from the ".regs" section of
4146 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
4148 * inferior.h (attach_flag): Export.
4149 * infcmd.c (run_command): use new target_create_inferior.
4150 * infrun.c (child_create_inferior): Don't return result.
4151 * Makefile.dist (VERSION): 3.91.4.
4153 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
4155 * breakpoint.c (bpstat_num): Handle breakpoints which have
4156 since been deleted, such as temporary breakpoints.
4157 infcmd.c (program_info): ditto.
4159 * core.c (core_file_command): Display the frame where the core
4164 * remote-vx.c (target_command): Merge in target command from
4165 targ-vx.c. A few other cleanups.
4167 * TODO, Projects: Lots more stuff to do...
4169 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
4171 Massive changes to wall off the remote-debugging interface
4172 behind a function vector. The port to handle VxWorks targets
4173 is also part of this.
4175 All files: Replace references to renamed functions,
4176 remove references to remote_debugging, remove references to
4177 have_include_file, have_core_file in favor of target_has_stack,
4178 target_has_memory, etc.
4180 * Modularize the breakpoint interface.
4181 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
4182 a breakpoint instruction.
4183 breakpoint.c: struct breakpoint's shadow_contents now sized as
4185 (insert_breakpoints): Vector to target to install breakpoints.
4186 (remove_breakpoints): Vector to target here too.
4187 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
4188 sparc-tdep.c (single_step): Use new breakpoint interface for
4189 the single-step breakpoints.
4190 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
4191 New file, contains routines to insert and remove breakpoints by
4192 reading out the old contents and later replacing them. This is
4193 how ptrace breakpoints work, and many remote systems as well.
4195 * tm-vxworks68.h: New config file, overrides a few things for
4196 Wind River's preferences.
4198 * target.h: New file, for transfer vector used to talk to the
4199 inferior (child, attached, core, exec, remote, etc). All accesses
4200 to the thing being debugged should come through these vectors.
4201 target.c: New file, routines to handle transfer vector.
4202 (various files): Add transfer vectors XXX_ops for the various
4203 targets and pseudo-targets (core files, etc) we support.
4205 * breakpoint.c (bpstat_stop_status): Further explorations of
4206 watchpoints and why things don't work all the time.
4207 (bpstat_alloc): New fn to allocate a bpstat and chain it.
4209 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
4210 the local gdbinit if it doesn't already have it.
4212 * core.c (core_ops): add and install.
4213 Allow core debugging without exec file.
4215 * dbxread.c (free_and_init_header_files): Merge two fns.
4216 (end_symtab): Free named symbol table when a new version comes in.
4217 (read_dbx_symtab): Relocate all kinds of symbols with base
4218 address. First step toward handling different text, data, bss
4220 (add_file_addr_command): Renamed add_file_command.
4221 (add_file_command): Vector to remote handler.
4222 Add "load" as an alias for "add-file" command.
4224 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
4225 non-returning functions.
4227 * exec.c: Add exec_ops, and push it as a target when an exec
4230 * infcmd.c (run_command): Pass executable file name and arg list
4231 separately when starting an inferior. Permit "run" when no exec
4232 file is specified, for VxWorks.
4233 (detach_command): Move to child_detach in inftarg.c.
4235 * inftarg.c: New file. Unix-child-specific routines, and the
4236 child_ops structure.
4238 * inferior.h (registers): Export "registers" as the way for
4239 target dependent register handlers to find gdb's local copy of
4240 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
4241 since it is now used by places that want wait_for_inferior to
4242 handle the grunge but want to see every trap from the inferior.
4244 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
4245 Eliminate remote_debugging hooks in terminal handling.
4247 * infrun.c: Replace start_inferior with child_create_inferior.
4248 Move all the hair of Unix shells and ptrace idiosyncracies into
4249 child_create_inferior, so remote handlers don't have to deal.
4250 Remove running_in_shell. Rename stop_after_attach to
4251 stop_soon_quietly, and use it in a few other places where we want
4252 to just call wait_for_inferior and get control back on the first
4253 trap. trap_expected now never takes a value > 1.
4254 (init_wait_for_inferior): Initialize static vars when a new
4257 main.c (gdbinit): Add new hook for .gdbinit file name, let
4258 it be overridden by config files as GDBINIT_FILENAME.
4259 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
4260 Both of these are used for VxWorks gdb.
4262 mcheck.c: rename include file "gmalloc.c" to avoid problems
4263 with system include file "malloc.c".
4265 param-no-tm.h: New include file, same as param.h but does not
4266 include the default "tm.h" file. This is used in files where
4267 the target is known, e.g. remote-eb.c or sparc-xdep.c.
4269 param.h: Now just a shell that includes tm.h and param-no-tm.h.
4271 remote-vx.c: New file, VxWorks remote debugging support. Uses
4272 RPC routines that are shared with the target system, in directory
4275 remote.c: Vectorize remote interface.
4277 source.c: Globalize source_path, and make an alias "l" for "list"
4278 since we now have the "load" command.
4280 sparc-xdep.c: Use new param-no-tm.h.
4282 symmisc.c (free_named_symtab): Add new function from Wind River.
4283 However, ifdef it out for now while we think about what it should
4286 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
4288 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
4289 non-Unix-children handle this with their own code in the target
4292 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
4293 source and target lists. Add vx-share to default list of include
4294 directories. Add new files to src and target lists: mem-break,
4295 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
4296 ${srcdir} versions of munch and createtags are used.
4298 * valops.c (find_function_addr): Split out of call_function.
4299 (call_function_by_hand): Rename call_function; this function
4300 calls functions in the target by laboriously patching the target
4301 word-by-word with the right stack, args, regs, etc.
4304 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
4306 Handle AMD 29000 a bit better.
4308 * remote-eb.c (readchar): Mask received char log to make it readable.
4309 (remote_start): Pass arguments down to executing program.
4310 Make startaddr unsigned.
4311 infrun.c (start_inferior): Accept args, pass them to
4313 infcmd.c (run_command): Pass args down to start_inferior.
4315 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
4316 the target object file format.
4317 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
4319 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
4320 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
4322 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
4324 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
4325 * TODO: We did a few things, we have more to do though.
4327 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
4328 * inflow.c (inferior_died): Clear deferred stores.
4330 * Debug problems with dummy frames and calls to the inferior.
4331 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
4332 * sparc-tdep.c (do_restore_insn): Simplify.
4333 (sparc_frame_find_saved_regs): Simplify and fix what we find.
4334 (sparc_push_dummy_frame): Simplify and fix what we push.
4335 (sparc_pop_frame): Slightly more hair here, deciding whether
4336 we are restoring a saved PC or returning to a return address in %i7.
4337 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
4339 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
4340 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
4341 * obstack.h (chunkfun): ditto.
4342 * defs.h (xmalloc, xrealloc): ditto
4344 * utils.c (quit): Grab the terminal from the child if necessary.
4346 * inflow.c (term_status_command): Rename to term_info, change
4349 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
4350 (is_delayed_branch): Speed up.
4351 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
4352 Still missing some float ops, and needs testing.
4354 * Support for input and output radixes other than base 10
4355 * defs.h (input_radix, output_radix): Declare.
4356 * expread.y (yyparse, parse_number): Handle changes of input
4357 radix, and ambiguous names-or-numbers in radixes >10.
4358 * printcmd.c (print_scalar_formatted): Print formatted hex
4359 numbers in varying column widths.
4360 * valprint.c (val_print): Use output_format to print scalar ints.
4361 (set_input_radix, set_output_radix, set_radix): Create.
4362 (set_output_radix): Set output_format from output_radix.
4363 (_initialize_valprint): add `set radix' but leave the others off.
4365 * main.c (execute_command): Let stupid questions be turned off.
4366 (_initialize_main): Handle "set stupidity", etc.
4368 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
4369 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
4371 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
4373 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
4374 bfd stuff is still screwed up, but with some manual work, it
4377 * breakpoint.c (bpstat_do_actions): Start over if a command
4378 proceeds the inferior, since the inferior will have stopped and
4379 will need to have its new stop-actions taken care of.
4381 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
4382 compiler fits, simplify it.
4384 * gdb.texinfo (directory command): Doc new dir command.
4385 source.c (directory_command): "dir" now puts things on the front
4386 of the path, moves dups up front, and handles multiple names
4387 on the command line, inserting each one in order. It also
4388 blows away cached line and full_filename info.
4390 * stack.c (backtrace_command): Skip "more stack frames follow"
4393 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
4394 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
4395 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
4396 The only odd one was Gould NP1, which had defined vprintf to
4399 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
4400 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
4401 variable, inspect_it.
4402 valprint.c (print_string, val_print): Use the global inspect_it
4403 to indicate whether to print in Epoch style or normal style.
4405 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
4407 * printcmd.c (call_command): add an alias for the "print" command
4408 which runs expressions and doesn't print the result if void.
4409 (print_command_1): implement it.
4411 * command.c: Remove #if 0'd code. Initialize all the fields
4412 in add_cmd (). Rename do_nothing_command to
4413 not_just_help_class_command, and make it externally visible.
4414 command.h: add user_commands to struct.
4415 * main.c (define_command): Don't overload c->function with a char
4416 string as well as a function pointer.
4418 * eval.c (evaluate_subexp): Reinstall tiemann changes to
4419 calling convention of value_struct_elt () that got dropped in
4422 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
4423 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
4425 * tm-sparc.h (POP_FRAME): replace some constants with defines.
4427 * sparc-xdep.c (store_inferior_registers): defer stores to regs
4428 until a good time (e.g. when we are about to run the child),
4429 saving ptrace calls.
4430 * infrun.c (proceed): handle DO_DEFERRED_STORES.
4431 * tm-sparc.h: define DO_DEFERRED_STORES.
4433 * sparc-xdep.c (store_inferior_registers): when storing float
4434 registers, don't store stack regs too. When storing the SP,
4435 however, DO store the stack regs too. This fixes a bug in which
4436 the dummy frame is not recognized when a call_function finishes,
4437 because its frame pointer (in the stack regs) was never
4439 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
4440 even though we don't know how to read them from an inferior.
4441 valops.c (call_function): Comment about storing SP.
4443 * infrun.c (save_inferior_status): Save away the original bpstat
4444 chain so it can be restored later. Install the copied version for
4445 use by whoever saved the status. It will be blow away by
4446 restore_inferior_status, and the original chain restored. This is
4447 important for people who have pointers into the original.
4449 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
4450 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
4451 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
4454 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
4456 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
4457 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
4458 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
4460 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
4462 * Merge Mike Tiemann's multiple inheritance changes from Sun.
4463 Store the baseclasses in a type struct starting from array element
4464 0 rather than from the unusual array element 1.
4466 dbxread.c: the above.
4467 (virtual_context): Add
4468 Read new debug information about which virtual function table
4469 a virtual function is from, and store it in fn_field.fcontext.
4471 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
4472 TYPE_FN_FIELD_STATIC_P.
4474 symtab.c: the above.
4475 valops.c: the above. Handle pointer casts of object *'s.
4476 (search_struct_method): Add.
4477 (value_struct_elt): First arg is now a pointer to a value, and is
4480 valprint.c: the above.
4481 values.c (value_virtual_fn_field): Add type arg. Handle
4482 offsetting to the proper object when calling virtual fns.
4484 (baseclass_addr): Add valuep arg.
4486 * README: Document the current state of BFD config (missing).
4487 * TODO, ChangeLog, Makefile.dist: Roll version.
4488 * WHATS.NEW: Add summary of changes since 3.5.
4490 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
4492 * dbxread.c (read_struct_type): Clear bit vectors whenever
4494 symtab.c (B_CLRALL): define.
4496 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
4497 using == rather than =. Huh... This fixes the dreaded problem
4498 wherein builtin_type_int becomes TYPE_CODE_FLT.
4500 * core.c (info_files): Show the inferior pid.
4502 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
4503 already knows how to look in the source directory.
4505 * Remove psymtab hair from many places. Remove duplicated code
4506 for searching symbol tables. Hide psymtabs from most places.
4507 Make it fast to get from a psymtab to its symtab.
4509 blockframe.c (blockvector_for_pc): Remove psymtab hair.
4510 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4511 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4512 dbxread.c: export psymtab_to_symtab, make it work if called N times.
4513 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
4514 new symtab completely. New psymtabs get symtab pointer
4515 initialized to zero. Remove MI warning printf.
4516 symtab.h: Comments. Add psymtab to symtab pointer.
4517 (PSYMTAB_TO_SYMTAB): New macro.
4518 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
4519 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
4521 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
4523 (print_frame_info): Avoid special-casing symbols that have not yet
4526 * source.c (open_source_file): Quick path if we have already
4527 located the source file by its full name.
4529 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
4530 find_pc_psymtab. When a name is found in the misc function
4531 vector, search the symbol table for its mangled name, not the
4532 name that the user typed.
4534 * bfd.h: Fix missing comment terminators, make #endifs match.
4536 * valarith.c (value_less): Handle unsigned int comparisons.
4537 Add FIXME about pointer compares, which assume host and target
4538 pointers are the same.
4540 * command.c (do_nothing_command): lint
4541 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
4542 fix comments on debug symbol format for visibility. Actually set
4543 visibility of symbols.
4544 main.c (echo_command): lint; use <readline/history.h>.
4545 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
4546 obstack.h (_obstack_blank): Rearrange pointer math to avoid
4547 pointing past end of allocated memory; saber complains.
4548 obstack.h: Declare the external functions that we use.
4549 valarith.h: use <string.h>
4550 solib.c (solib_add): lint.
4552 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
4554 * main.c (initialize_main): Default info_verbose to off, now that
4555 symbol reading is fast.
4556 (quit_command): Avoid clobbering exec_bfd while quitting.
4558 * Initial BFD (binary file diddling library) merger:
4559 coffread.c: Change AOUTHDR to struct exe_hdr.
4561 core.c: initialize initialized data at compile time.
4562 (core_file_command): Move from coredep.c, convert to bfd.
4563 (xfer_core_file): Convert to bfd.
4564 exec.c (exec_file_command): use bfd routines.
4566 mips-tdep.c: Remove exec_file_command and friends.
4569 * coredep.c: (fetch_core_registers) Convert core_file_command to
4570 fetch_core_registers.
4571 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
4573 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
4574 (my_bfd_read): More bogosity, which I don't think we call.
4575 (program_name): Remove this atrocity asap!
4577 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
4580 values.c: allocate_repeat_value was not clearing the
4581 optimized_out field.
4582 (value_static_field): minor stylistic fix (wrong macro was used).
4583 valops.c (value_struct_elt_for_address): didn't work for C++
4586 * signame.c (_initialize_signame): Initialize signal names once.
4588 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
4589 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
4590 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
4592 * remote-eb.c: Support user-settable baud rates on the serial port.
4594 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
4596 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
4598 * tconfig/sun3os4: Remove warning about native assembler,
4599 since it also occurs in the xconfig file.
4601 * findvar.c (registers): Allocate some slop after `registers'
4602 to prevent stray accesses from trashing the next variable.
4604 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
4605 on the sun-3, by changing the #ifdef from `sun3' (which is not
4606 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
4607 vars, which happened to follow `registers' in the executable.
4609 * readline/history.c (history_search): Heed gcc-2's advice
4610 and parenthesize && inside ||).
4612 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
4613 tm-29k.c: Insert FSF copyright headers.
4615 * remote-eb.c: Better comments.
4617 * Makefile.dist: Update to 3.91.6.
4618 * TODO: note PREPARE_TO_STORE problem.
4620 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
4622 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
4624 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
4626 * infrun.c (wait_for_inferior, at end): Don't set up
4627 prev_* if the inferior no longer exists.
4629 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
4630 CANNOT_EXECUTE_STACK.
4631 valops.c (call_function): Use it.
4633 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
4635 * inferior.h (PC_IN_CALL_DUMMY): New macro.
4636 infrun.c (wait_for_inferior, 2 places): Use it.
4638 * values.c (value_being_returned): Only use
4639 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
4641 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
4642 right thing for remote-eb.c.
4644 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
4645 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
4647 * blockframe.c: Put get_frame_saved_regs inside #if !defined
4648 (FRAME_FIND_SAVED_REGS).
4650 * findvar.c ({fetch,store}_registers): Check for
4651 REMOTE_{FETCH_STORE}_REGISTER macro.
4653 * findvar.c (get_saved_register): Add argument lval and
4654 change meaning of argument addr.
4655 findvar.c: Change calls to get_saved_register to reflect
4656 new calling convention.
4657 valops.c (value_assign): Use get_saved_register instead of
4658 find_saved_register.
4660 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
4662 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
4663 an (uninitialized) pointer to one. Use "&" when passing it
4666 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
4668 * coffread.c (getfilename): Use DGUX x_offset and x_name if
4671 * coffread.c (symbol_file_command): Put semicolon after
4673 Put safe_to_init_tdesc_context in #if defined (TDESC).
4674 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
4675 coffread.c: #include <sys/stat.h>.
4676 (read_coff_symtab): Typo: in_source_files -> in_source_file.
4677 Add missing ')' in check for "lc%" and friends. Remove
4679 Declare read_one_sym() at top of file.
4680 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
4681 MC68WRMAGIC can have the same value without causing a duplicate
4684 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
4686 * Allow a Makefile to be built without building the
4687 tm and xm file links that screw up builds in subdirectories.
4688 This is done with `config.gdb none', then you can do things
4689 like `make gdb.tar.Z'.
4690 * tconfig/none: Config file for no target system
4691 * xconfig/none: Config file for no host system
4692 * config.gdb: If no TM or XM files are called out by the
4693 host or target file, don't make links for them.
4695 * cplus-dem.c: Add documentation.
4697 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
4698 simple error, so the user's gdb doesn't crash due to some object
4699 file problem (e.g. somebody is rebuilding the file out from under
4702 * printcmd.c (print_address_symbolic): demangle the symbol.
4704 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
4705 Motorola copyrights in it. Make "make gdb.tar.Z" work.
4706 (alldeps.mak): sort and uniq all results from this; duplicates
4707 hose gdb.tar.Z link building. Remove RCS files from
4708 tconfig and xconfig. Add config files for sun386. Add
4709 a few odd files to OTHERS and HFILES.
4711 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
4713 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
4714 Roll version number to 3.91.5. Make lint work in bindir.
4716 * README: Document cross-debugging and new file structure.
4718 * blockframe.c: Lint. Include "value.h" to declare read_register.
4719 (find_pc_partial_function): remove duplicate line.
4721 * command.h: Lint. Declare error_no_arg and dont_repeat.
4723 * tm-news.h: Remove inadvertently duplicated stuff.
4725 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
4726 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
4728 * config.gdb: Allow `config.gdb host target' form. Clean
4729 up previous change that printed bogus messages when you just said
4732 * core.c: #include "command.h" for lint.
4735 * main.c: Remove some casts of enums. Lint.
4742 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
4744 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
4745 read it from memory. This will allow us to save ptrace calls
4746 eventually. Changed caller single_step too.
4748 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
4749 that we aren't going to use, saving many ptrace calls, especially
4750 when watchpointing or single stepping. Use some #define's for
4752 (store_inferior_registers): Ditto.
4753 (core_file_command): Use some #define's for constants.
4755 * tm-sparc.h: Add #define's for some register numbers, so we
4756 can eliminate the use of random constants in sparc-xdep.c.
4758 * stack.c (frame_command, print_frame_info, up_command,
4759 down_command) Remove frame_changed, since it
4760 causes a bug and doesn't seem to do anything useful. In some
4761 places it was used as a flag, in others as a stack level (?).
4763 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
4764 default is to use the portable (vprintf) version rather than the
4766 * xm-news.h (MISSING_VPRINTF): Add.
4768 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
4770 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
4772 * Remove stuff that forces -Bstatic linking of gdb, and warnings
4773 about linking debugged programs -Bstatic in the sun?os4 config
4774 files in tconfig and xconfig subdirectories.
4776 * main.c (main): Remove unreached exit(0) now that we exit
4779 * Create TODO file for online bug list. There are too many
4780 "little" bugs to keep track of on paper.
4782 * Change Projects file to refer to bug-gdb@cygnus.com
4783 rather than kingdon@ai.
4785 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
4787 * Makefile.dist (VERSION): 3.91.4 now.
4789 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
4790 (condense_misc_bunches): Add sanity check that misc_count is
4791 the same as the number of symbols in the bunch.
4793 * coffread.c: rename init_misc_bunches. Pass an argument
4794 to condense_misc_bunches (a zero).
4796 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
4797 every time we are called; don't rely on our caller to do it.
4798 (add_file): Remove call to init_misc_bunches.
4800 * mipsread.c: Only warn, don't error, if unknown symbol types.
4801 This keeps an old gdb from falling on its face if it sees newly
4802 extended symbol info. Rename init_misc_bunches.
4804 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
4806 * Merge in changes from Per Bothner for DECstations and other
4807 MIPS stuff. The rest is Bothner speaking:
4809 The next message is a merger of Alessando Forin's mips port with
4810 mine. I've tried to use my good if biased judgment to get
4811 the best of both. It *does* need testing.
4813 Some of the changes are general, *not* mips-specific.
4816 Didn't believe in little-endian bit order.
4817 There are still inconsistencies about whether flags
4818 like BITS_BIG_ENDIAN are integer (#if ...) or
4819 boolean (#ifdef ...). I tried to paper over them.
4821 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
4822 Moved some misc_function code that was common to
4823 {dbx,coff,mips}read.c to symtab.c.
4824 In the process, I think I cleaned things up a bit.
4825 At the same time, moved obsavestring and obconcat to symtab.c.
4828 Removed obsolete condense_addl_misc_bunches (use
4829 condense_misc_bunches(1) instead).
4832 Needed to include <sys/dir>, at least on DECstations.
4834 valops.c, mips-tdep.c, tm-mips.h:
4835 Added PUSH_ARGUMENTS macro to support funny argument-pushing
4836 conventions (when STACK_ALIGN is insufficient).
4837 Needed on mips, where doubles need 8-byte alignment,
4838 but ints only need 4.
4841 Removed cruft that was not being used.
4842 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
4845 Print $ before register-names (I think that makes things a little
4847 Never print two instructions, even if one delays.
4848 Removed hex-disassemble set_cmd. (This is not mips-specific,
4849 so I think the argument is whether it is generally worthwhile or not.
4850 I'm inclined to think not, given how easy it is to
4851 convert between radixes in gdb.)
4854 This is basically Alessando's code.
4855 It doesn't use obstacks; I changed it to use obstacks
4856 in a few minor places where using malloc causes a
4857 memory leak. (Probably, more places could/should be changed.)
4858 I added record_misc_function where it was missing.
4859 In symbol_file_command and add_file_command, I tried
4860 to make the code consistent with more recent versions.
4861 Minor sylistic changes in parse_procedure.
4862 Make a .gdbinfo. psuedo-symbol point back to the real
4863 procedure symbol (using the isym field).
4866 This is basically from my port, but with a lot of details
4867 and a number of routines merged in from Alessando's version.
4868 I basically used my code "raw" backtrace (use heuristics
4869 from the actual code, rather than symbol table info) - though
4870 the idea is Alessandro's. I feel my code is a little cleaner
4871 here, particularly in being a little more flexible, such as being
4872 able to handle gcc-produced code (which it now can).
4873 It also doesn't do frame caching (which is not useful
4874 more recent gdb versions).
4875 I also used my code for push_/pop_dummy, more or less.
4876 I tried to incorporate AF's code for testing sigtramp
4877 while backtracing; I probably got it wrong.
4878 Added mips_print_register, which tries to scrunch as much
4879 information as possible on a screen...
4880 Removed the skip-prologue set_cmd. As with hex-disassemble (see
4881 under mips-pinsn.c), I don't see anything mips-specific here,
4882 and I don't see it being all that useful anyway.
4885 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
4886 Use more register names (rather than hard-cases numbers).
4888 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
4890 * Hack up 3.90.11 changes:
4892 * Makefile.dist (depend): parameterize $(GCC).
4893 Add solib.c and solib.o.
4894 (readline): Fix vpath for both absolute or relative SRCDIR.
4896 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
4897 Also, let the part I didn't understand at least compile so
4898 I can test the rest. FIXME.
4900 * dbxread.c: Fix thinko using strcmp.
4901 (init_psymbol_list): declare static.
4902 (partial_symbol_file_open): Comment cleanups better, avoid
4903 cleaning up the string table since the caller will do that.
4904 Move the stat for mod time into symbol_file_command, temporarily.
4905 (There should be a mod time for each symbol file, eventually,
4906 to control its rereading. FIXME.)
4908 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
4909 SunOS, which gives error for shared libs otherwise. (From
4910 Schaefer, probably FIXME needs work for portability.)
4912 * solib.c: Move #include "param.h" to work.
4913 Lowercase all the Uppercase Letters In the Messages.
4914 (find_solib): Clean up inferior_so_name for debug printouts.
4915 Allow no argument, to mean all shared libraries.
4917 * symmisc.c: include param.h to get CLEAR_SOLIB.
4919 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
4921 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
4922 to 3.90.11. ChangeLog entries below are from this.
4924 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)

4930 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4934 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
4936 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
4938 * sparc-opcode.h Added single-operand version of rett.
4940 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4942 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
4943 Put parens around gcc_p in expansion.
4945 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
4947 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
4949 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4951 * Changes for Sun shared libraries:
4952 blockframe.c (find_pc_partial_function): If a non-text symbol
4953 is found, set *address = pc - FUNCTION_START_OFFSET.
4954 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
4955 Disable breakpoints instead of giving an error.
4956 source.c (select_source_symtab): Initialize cs_pst.
4957 symmisc.c: Call CLEAR_SOLIB if defined.
4958 symtab.h: Make text{low,high} CORE_ADDR not int.
4959 (psymtab): New field addr.
4961 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
4962 (record_misc_function): Give correct type for N_DATA symbols.
4963 (condense_misc_bunches): do "misc_function_count = j" regardless
4965 Take code which is shared between symbol_file_command and
4966 add_file_command and put it into partial_symbol_file_{open,read}.
4967 Split add_file_command into add_file_command and add_file.
4968 Make psymtab_to_symtab read in the string table if the file
4970 Two new parameters to read_dbx_symtab and start_psymtab.
4971 tm-sunos.h: New file.
4973 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4975 * infcmd.c: Change cont_command to continue_command and "cont"
4978 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4980 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
4982 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
4984 * values.c (USE_STRUCT_CONVENTION): Check for structures of
4985 size 1,2,4,8 rather than size < 8.
4987 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
4988 as necessary, not just once.
4990 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
4992 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4994 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
4996 * tm-news.h: Add CALL_DUMMY_*.
4998 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
5000 * config.gdb: In list_host, list_target, use ${i}, not $i.
5002 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5004 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
5006 * sparc-opcode.h: Change all store floating-point state register
5007 instructions to have the right match & lose fields.
5009 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5011 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
5013 config.gdb: If srcdir != ., create readline directory and
5014 copy a makefile into it.
5016 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
5017 consistency with POSIX.
5019 * breakpoint.c (bpstat_stop_status): Disable watchpoint
5020 when we exit its exp_valid_block.
5022 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
5024 * Makefile.dist: Bump version to 3.91.3.
5026 * Clean up handling of breakpoint commands (somewhat).
5027 Prompted by Tiemann bug report "cont 10" doesn't work any more.
5029 inferior.h: Add breakpoint_proceeded to inferior status struct
5030 and globals; save it and restore it.
5031 (clear_breakpoint_commands): Cleanup, remove old #define.
5033 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
5034 (save_inferior_status, restore_inferior_status): handle it also.
5035 (proceed): Remove earlier code that set breakpoint_proceeded.
5036 It is now set only in clear_proceed_status.
5037 (clear_proceed_status): Cleanup, use bpstat_clear rather
5038 than clear_breakpoint_commands. No callers need the stop_bpstat
5039 between clear_proceed_status and proceed.
5041 infcmd.c: Add breakpoint_proceeded definition and comment.
5042 (cont_command, jump_command, signal_command): Move call to
5043 clear_proceed_status right next to call to proceed.
5045 breakpoint.c (bpstat_do_actions): Avoid clobbering our
5046 caller's argument while running down the chain of breakpoints.
5047 Use new variable "breakpoint_proceeded" to determine when
5048 a command that it executes moves the inferior past the
5050 (bpstat_clear): Handle NULL argument.
5051 (bpstat_clear_actions): Avoid useless call to
5052 breakpoint_auto_delete.
5053 (delete_breakpoint): Clean up bpstat's that are pointing to
5054 the deleted breakpoint from the stop_bpstat chain.
5055 (breakpoint_auto_delete): Simplify.
5057 * Clean up handling of EOF, error on stdin, etc. This was
5058 prompted by a network problem that caused gdb to go into an
5059 infinite loop filling up its malloc'd memory.
5061 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
5062 not clear_breakpoints_commands, which is now gone.
5063 (main): If command_loop returns (e.g. from EOF on stdin), do
5064 a quit_command (looping back to command_loop if quit_command
5065 doesn't really quit).
5066 (command_loop): check result from command_line_input and
5067 exit if it returns NULL, rather than passing the NULL to
5069 (gdb_readline): Free malloc'd result space before returning
5072 * utils.c (query): Handle C-d to mean "yes", just as if the
5073 input was not a terminal. Also avoid infinite loop if EOF
5074 occurs in mid-input-line before newline. This allows
5075 query to be used at EOF on stdin with reasonable results.
5077 * infrun.c (proceed): Set breakpoint_proceeded.
5079 * values.c (value_as_long): Avoid infinite recursion for enums.
5080 (_initialize_values): Fix typo in help msg (kingdon).
5082 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
5083 RL_LIB for linking. This allows -lreadline for linking
5084 and nothing for dependencies, once readline is a real library.
5086 * config.gdb: Jim Kingdon: give useful error message if the
5087 host or target type is not recognized.
5089 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
5090 it just defines it. Dumb, but deal with it.
5092 * Jim Kingdon suggests:
5093 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
5095 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
5097 * Makefile.dist (VERSION): Bump version # to 3.91.2.
5099 * Clean up Bothner's changes.
5101 * blockframe.c (clear_pc_function_cache): New function.
5102 * blockframe.c: remake cache_pc_function_* static.
5103 * dbxread.c (symbol_file_command): remove references to
5104 cache_pc_function_* variables.
5105 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
5106 * printcmd.c: Avoid kludging a global variable (addressprint)
5107 to avoid printing the address of a string twice. Instead,
5108 pass the format letter 's' down low enough that it can be seen
5109 to avoid this problem.
5110 (print_formatted): Pass format arg to value_print.
5111 (restore_addressprint): Remove function.
5112 (do_examine): Avoid hacking addressprint, cleanups and such.
5113 (print_frame_args): Add a comment to a Bothner change.
5114 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
5115 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
5116 to wipe out the values cached in blockframe.c.
5117 * symtab.c (find_method): Add comment saying how big you must
5118 allocate to be "big enough". Per being terse again.
5119 * valprint.c (val_print): Handle format letter "s" to print
5120 strings without addresses. Add comment to vtbl printing code
5121 which casts with wild abandon. Rearrange reference-printing
5123 @0xaddr: value (print w/addressprint)
5124 value (print w/~addressprint)
5125 @0xaddr (parameter lists w/addressprint)
5126 or nothing (parameter lists w/o addressprint)
5128 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
5130 * Merge more changes from Per Bothner:
5132 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
5133 annoying) that I tried to improve it. Here are my suggestions.
5135 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
5138 Do automatic de-reference when taking the address of a reference.
5140 Don't deref_ref when printing parameter lists.
5142 More attempts at treating refernences properly.
5144 In val_print, if deref_ref==0, don't print dangling " = ".
5146 Add COERCE_REF macro, which de-references an REF.
5148 * Merge changes from Per Bothner:
5150 * Fixed (Sony news)-specific configuration problems.
5151 * Fixed other problems with using vanilla pcc and libc (enum problems;
5152 assumption that vsprintf exists).
5153 * Some major speed-ups (finc_pc_partial_function now caches a match;
5154 parsing avoids duplicate symbol_lookup calls).
5155 * Changed handling of baseclasses (no longer use baseclasses field
5156 of struct type, use the first n_baseclasses fields instead).
5157 * Various minor changes/fixes, most C++-related.
5160 Cache the most previous match from find_pc_partial_function.
5161 (Save both low and high ends of matching function's pc range.)
5162 This speeds up the loop of infrun.c:wait_for_inferior quite
5163 a bit, and makes step/next commands much zippier.
5165 Added an enum->int cast (otherwise, some compilers barf).
5167 No longer set baseclass offset to 0, since multiple
5168 inheritance now mostly works.
5169 Added a number of casts, to shut up compiler warnings
5170 (after stabs where made enums, not ints).
5171 When discarding a symbol table (in symbol_file_command),
5172 must clear the cache introduced in blockframe.c.
5173 Don't convert $vtbl_ptr_type to vtbl any more.
5174 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
5175 Mask off sign bit emitted by g++ for virtual table offset.
5176 Set voffset to -1 (not 1) for static member functions.
5178 Changed parsing/lexing of names to avoid doing symbol lookup twice
5179 (once when lexing to determine symbol class, once for real).
5180 Now only call symbol_lookup once. Fields of 'this' win especially big.
5182 Subpress printing addr twice in the case of 'x/s addr'.
5184 lookup_basetype_type is no longer used.
5185 Add find_methods as recursive helper function to decode_line_1.
5186 This allows multiple inheritance to work.
5187 Also, once one or more matches has been found, do not look in
5188 base-classes. (Baseclass methods would be overridden, anyway.)
5190 Removed baseclasses array in struct type.
5191 Instead of using baseclasses[i], use fields[i-1].
5192 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
5193 Changed sign convention of voffset (previous was inconsistent).
5195 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
5197 Used to assume existence of vsprintf. Re-written to not need it
5198 if HAVE_VPRINTF is undefined.
5200 typecmp was too pessimistic. Made it less so.
5202 Don't print space after address.
5203 If vtable points to a misc symbol (with 0 offset), print it,
5204 since that indicates the actual class of the object.
5205 Changed ype_print_derivation_info to use new inheritance
5206 scheme (without baseclasses vector).
5208 In value_primitive_field, fixed some bugs left over from previous set of fixes.
5209 Also, changes needed because TYPE_BASECLASSES were removed.
5211 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
5213 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
5216 If there is no path set, and the symbols don't indicate what directory
5217 a file was compiled in, look in the current directory. But either
5218 a path or a known compilation directory will prevent this.
5221 Three independent bug fixes:
5222 * Remove the #if 0 block that breaks some stuff.
5223 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
5224 adapt gdb to either SunOS 4.0.* or 4.1.
5225 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
5228 Instantiate the class T when looking for methods in it. (Tiemann@sun)
5231 (type_print) Demangle the name being printed.
5232 (type_print_base) Handle botched demangling without coredump (tiemann).
5235 (check_stub_method): Document routine.
5236 (tiemann) fix bug for no-arg functions
5237 Avoid clobbering beyond end of malloc'd storage.
5238 Terminate the argument list properly.
5240 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
5242 * Changes merged by John Gilmore:
5245 In breakpoint_1, use new print_address_symbolic instead
5246 of find_pc_partial_function. (This forces use of assembler-level
5247 addresses, and avoids misleading non-mangled source-level names.)
5249 Generalize ansi argument such that -1 means skip arglist totally.
5250 Removed global variable print_ansi_qualifiers (which made
5251 code non-reentrant), in favor of extra explicit arguments
5252 to internal routines.
5254 Add new helper function print_address_symbolic.
5255 Use find_pc_misc_function instead of find_pc_partial_function
5256 (since we want assembler-level symbols here).
5258 Print unknown function as just "f (...)", not "f (...) (...)".
5259 Use new fputs_demangled explicitly.
5261 Fixed a typing violation (problem: value.h cannot be imported
5262 without renaming many variable in this file).
5263 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
5264 decode_line_1: Moved forward some never-reached code.
5265 Made decode_line_2 skip function prologues correctly.
5267 fputs_filtered should not demangle by default.
5268 Add new fputs_demangled to demangle on demand..
5270 Change value_struct_elt to use value_primitive_field (using recursive
5271 utility function search_struct_field). This allows foo.bar to work
5272 for multiple inheritance (so far only for data fields).
5273 Change check_field in the same way (recursive helper function
5274 to support multiple inheritance).
5275 (Note: there are more of these problems that I haven't fixed.
5276 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
5277 value_of_this: 'this' symbol name is now just "this", note "$this".
5279 Don't print static members.
5280 Avoid printing "members of <type>" if there are none.
5281 Simplified type_print_derivation_info by merging duplicate code.
5282 Remove useless blank lines in type_print_base (ptype command).
5284 Added declaration of new routine value_primitive_field.
5286 Added value_primitive_field which is generalized version of
5287 value_field that can handle multiple inheritance (non-zero offsets etc).
5288 Re-implemented value_field to call value_primitive_field.
5290 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
5292 * infcmd.c -- insert else to avoid 'delete env' coredump when you
5293 delete the whole environment. Karl Berry reported the bug.
5294 * source.c - fix openp to avoid //'s in filenames, which
5295 trigger an Emacs bug causing it to not be able to find files
5296 when running gdb in a window.
5297 * dbxread.c - zap the #if 0 that botches the add-file code.
5298 It seems to work a lot better without all the code commented out.
5300 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
5302 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
5305 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
5307 * Makefile - added a ${CFLAGS} to a couple of entries,
5308 added remote-sa.sparc.c
5309 * added remote.sa-sparc.c, a modification of remote.c
5310 which conducts a dialog directly with the SparcStation prom.
5311 * breakpoint.c, infrun.c, sparcdep.c added
5312 remote_insert_breakpoint(), and remote_remove_breakpoint()
5313 to breakpoint.c instead of directly writing breakpoint instructions.
5314 * sparcdep.c on remote_debugging,there is no need
5315 to remove signle step breakpoint instructions.
5316 * main.c added "-epoch" flag and "int epoch_interface" to main.c
5318 * printcmd.c - epoch interface sends lisp expressions to open up
5319 epoch windows on inspection.
5320 * valprint.c - added arrayprint, and addressprint and made adding
5321 format controls easier
5322 * wait.h added a couple of undef's because we were getting
5323 complaints about WSTOPSIG and WTERMSIG begin redefined.
5326 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
5328 * symtab.c (decode_line_1): Add support for handling method stubs
5329 in the type information.
5331 Tue Jul 3 09:39:18 1990 Michael Tiemann (tiemann at masham)
5333 * values.c (baseclass_addr): Run loop from INDEX+1 to
5334 N_BASECLASSES; otherwise, we can still get into a loop.
5335 @@ This should be restructured to use a cleaner search strategy.
5337 Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
5339 * dbxread.c (define_symbol,read_type): Grok GNU C++'s new
5340 abbreviation "Tt" for tags which have the same name as their
5343 Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham)
5345 * symtab.c (list_symbols): add ability to set breakpoints on all
5346 the functions which match a particular regular expression.
5348 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
5350 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
5351 should print ANSI qualifiers (such as `const' and `volatile').
5352 All callers changed to call with ANSI == 1, except from
5353 `check_method_stub', which uses old-style syntax.
5355 * symseg.h (struct fn_field): Remove unneccessary `args' field.
5356 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
5358 * values.c (check_stub_method): New function.
5360 * cplus-dem.c (do_type): Handle "long long" (encoded as 'x').
5362 * dbxread.c (read_type): Handle new GNU C++ method type stubs.
5363 * valprint (type_print_base): Ditto.
5365 * symtab.c (gdb_mangle_typename): New function.
5367 Tue Jun 5 00:18:43 1990 Michael Tiemann (tiemann at gzilla)
5369 * breakpoint.c (catch_command): New function. Provides a
5370 mechanism to set breakpoints based on catch clauses.
5371 (disable_catch): Similar, but disables breakpoints on catch
5373 (delete_catch): Similar, but deleted breakpoints on catch clauses.
5375 Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla)
5377 * blockframe.c (blockvector_for_pc): New function.
5378 * blockframe.c (block_for_pc): Changed to call
5379 `blockvector_for_pc' and get the block itself.
5381 * stack.c (catch_info): New function. Prints info about
5382 exceptions which can be caught in the current frame.
5383 * stack.c (print_frame_label_vars): New function. Similar to
5384 `print_frame_local_vars'.
5385 * stack.c (print_block_frame_labels): Prints out labels that are
5386 defined in this frame. These labels are exceptions that can be
5389 * dbxread.c: Updated to handle N_CATCH symtab types.
5391 Thu May 3 22:10:00 1990 Michael Tiemann (tiemann at teacake)
5393 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
5394 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
5395 when printing the type.
5397 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)
5399 * valprint.c (val_print): Use `baseclass_addr' to access the
5400 baseclasses pointed to via the derived class object at VALADDR.
5402 * values.c (baseclass_addr): New function. Casts derived pointers
5403 to baseclass pointers taking virtual baseclasses and multiple
5404 inheritance into account.
5406 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5410 Fri May 4 12:12:55 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5412 * breakpoint.c (watch_command, bpstat_stop_status): Deal with
5413 exp_valid_block field correctly.
5415 * infrun.c (wait_for_inferior): When checking "don't even think
5416 about breakpoints" if stop_signal == SIGTRAP && trap_expected,
5417 also check step_resume_breakpoint.
5418 Insert breakpoints and continue (not step) if
5419 step_resume_break_address != NULL, even if another_trap.
5420 If trap_expected and we enter sigtramp, then set up a
5422 If trap_expected is set when we hit the step_resume_break,
5424 When calling resume and trap_expected says tell resume to step
5425 (2 places), also check step_resume_break_address.
5427 * infrun.c (wait_for_inferior): Don't set
5428 prev_{pc,sp,func_{start,name}} before calling wait ().
5429 Do set them after exiting loop.
5430 Move their declarations outside functions.
5431 (start_inferior): Initialize them.
5433 Thu May 3 00:15:11 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5435 * infrun.c (wait_for_inferior, after check for trap_expected > 1):
5436 Restore old code which distinguishes between trap_expected and
5437 running_in_shell, just make the latter take any non-TRAP signal,
5440 * values.c (allocate_value): Zero VALUE_OPTIMIZED_OUT flag.
5442 * Makefile.dist (pinsn.o): Use PINSN_CC to compile.
5443 xconfig/3b1 (CC,PINSN_CC): Define.
5445 * xconfig/altos, altos-dep.c: Rename altos-dep.c to altos-xdep.c.
5449 * breakpoint.c (bpstat_stop_status),
5450 infrun.c (wait_for_inferior) [SHIFT_INST_REGS]: New code.
5452 * param.h, tm-88k.h: Define ADDR_BITS_*.
5453 infcmd.c (jump_command, read_pc), infrun.c (wait_for_inferior),
5454 printcmd.c (do_one_display): Use them.
5456 * utils.c: Split #ifdef USG into a USG_UTILS and a QUEUE_MISSING.
5457 xm-88k.h: Define USG_UTILS.
5459 Wed May 2 00:05:33 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5461 * printcmd.c (printf_command) [__INT_VARARGS_H]: New code.
5462 (printf_command): Add from_tty parameter.
5464 * valprint.c (value_print): Check VALUE_OPTIMIZED_OUT flag.
5466 * value.h: Add optimized_out field and change lazy field to
5467 char. Add macro VALUE_OPTIMIZED_OUT.
5469 * i386-pinsn.c: Change from Eirik Fuller to write to stream directly
5470 instead of stuffing things in buffers (oappend, etc).
5472 * breakpoint.c (bpstat_do_actions): If *BSP is set to NULL by
5473 execute_command, exit both loops.
5475 * Makefile.dist: Don't set TARGET_ARCH. Add .c.o rule.
5477 Tue May 1 17:07:23 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5479 * Makefile.dist (RAPP_OBS, rapp),
