179 without symbols. The other is the incorrect passing of char
180 arguments during expression evaluation (ie: p foo('a','b') would

196 * testsuite/gdb.t16/gdbme.c, testsuite/gdb.t17/gdbme.c: Add calls
197 to malloc() so that we can test GDB eval of dynamically created
198 arrays (like char strings in `print "foo"').

1230 * xm-vaxult2.h: New file.
1231
1232 * c-exp.y (parse_number): Change high_bit to unsigned.
1233 * demangle.c: Change all references to cfront to ARM, since the
1234 actual algorithm is the one specified in the Annotated Reference
1235 Manual. This was confusing users into thinking that full cfront
1236 support was implemented.
1237 * dwarfread.c (CFRONT_PRODUCER): Remove, was never really used.
1238 * eval.c (evaluate_subexp): For STRUCTOP_PTR pass the arg type
1239 directly to lookup_struct_elt_type, which will do the
1240 dereferencing itself.
1241 * gdbtypes.c (lookup_struct_elt_type): Expand comments. Fix
1242 NULL dereferencing bug for unnamed structs, comment out
1243 questionable code.

1246
1247 * coffread.c (process_coff_symbol): Change PCC argument correction
1248 so that it only happens on big-endian targets; so that it only
1249 happens if the short or char argument is aligned on an int
1250 boundary; and so that it changes the location, rather than the
1251 type, of the argument. These changes tend to parallel similar
1252 (old) changes in stabsread.c.
1253
1254 * coffread.c (coff_read_enum_type): Use the specified size for
1255 enums, don't assume that they are int-sized.
1256
1257 * c-valprint.c (c_val_print): Don't assume enums are the same as
1258 ints.
1259
1260 * coredep.c: Handle NO_PTRACE_H in coredep.c. Fix by Michael
1261 Rendell, <michael@mercury.cs.mun.ca>.

1286
1287 * symtab.h (SYMBOL_INIT_DEMANGLED_NAME): Initialize contents
1288 of demangled name fields to NULL if no demangling exists for
1289 a symbol. SYMBOL_INIT_LANGUAGE_SPECIFIC does this for new
1290 symbols if their language is known at the time they are created,
1291 but sometimes the language is not known until later.
1292
1293 * ch-typeprint.c (chill_print_type_base): Name changed to
1294 chill_type_print_base to match pattern for C and C++ names.
1295 * ch-typeprint.c (chill_print_type): Change "char" to "CHAR"
1296 to be consistent with other usages.
1297 * ch-typeprint.c (chill_type_print_base): Add support for

1332 floating point coprocessor.
1333 (mips_push_dummy_frame): If not mips_fpu, don't save floating
1334 point registers.
1335 (mips_pop_frame): If not mips_fpu, don't restore floating point
1336 registers.
1337 (_initialize_mips_tdep): New function; let the user reset mips_fpu
1338 variable.
1339 * tm-mips.h (EXTRACT_RETURN_VALUE, STORE_RETURN_VALUE): If not
1340 mips_fpu, don't use fp0 as floating point return register.
1341 (FIX_CALL_DUMMY): If not mips_fpu, don't save floating point
1342 registers.
1343
1344 Mon Feb 22 07:54:03 1993 Mike Werner (mtw@poseidon.cygnus.com)
1345
1346 * gdb/testsuite: made modifications to testcases, etc., to allow
1347 them to work properly given the reorganization of deja-gnu and the
1348 relocation of the testcases from deja-gnu to a "tool" subdirectory.
1349
1350 Sun Feb 21 10:55:55 1993 Mike Werner (mtw@poseidon.cygnus.com)
1351
1352 * gdb/testsuite: Initial creation of gdb/testsuite.
1353 Migrated dejagnu testcases and support files for testing nm to
1354 gdb/testsuite from deja-gnu. These files were moved "as is"
1355 with no modifications. This migration is part of a major overhaul
1356 of dejagnu. The modifications to these testcases, etc., which
1357 will allow them to work with the new version of dejagnu will be
1358 made in a future update.

1387 * main.c (print_gdb_version): Update copyright year to 1993.
1388 * nm-hp300bsd.h: Decide whether this is BSD 4.3 or 4.4,
1389 conditionalize this file on it. FIXME, right way is to split
1390 these into two config files.
1391 (ATTACH_DETACH): Define for BSD 4.4
1392 (PTRACE_ARG_TYPE): caddr_t for BSD 4.4, unset for 4.3.

1570
1571 * coffread.c (getfilename): Eliminate COFF_NO_LONG_FILE_NAMES
1572 test, which is apparently left over from when we used native

2403 stop_func_start will reflect the proper address of the target
2404 routine, not of the stub that we may be traversing to get there.
2405 * tm-hppa.h: define SKIP_TRAMPOLINE_CODE and IN_SOLIB_TRAMPOLINE
2406 to deal with the stubs that PA compilers sometimes stick between
2407 callers and callees. Also, define FLAGS_REGNUM for access to the
2408 `flags' pseudo-reg.

2410 memcpy, not bcopy.
2411 * (CANNOT_STORE_REGISTER): New from Utah. Says that we can't

2684 Make most functions static.
2685 * hppah-nat.c: General cleanups, remove BSD specific code (since
2686 that all lives in hppab-nat.c).
2687 * hppah-tdep.c (frame_chain_valid), tm-hppa.h (FRAME_CHAIN):
2688 Change sense of test against inside_entry_file(). This fix is
2689 from U. of Utah.
2690 * tm-hppa.h (PUSH_DUMMY_FRAME, POP_FRAME): Use char * for 2nd arg
2691 to read/write_register_bytes().
2692 * gdbtypes.h: Remove const from decl for cplus_struct_default to
2693 work around PA-GAS assembler bug. Also, add trailing */ to some

2696 Same reason as above.
2697
2698 Wed Dec 9 19:53:25 1992 John Gilmore (gnu@cygnus.com)
2699
2700 * mipsread.c (parse_symbol): When checking whether a structured
2701 type is an enum, check qualifiers of its first member, as well as

2817
2818 * tm-sun4sol2.h: Add CPLUS_MARKER. Solaris 2.0 requires '.'

2844 a single blank as the name of nameless enumerations. Recognize
2845 this special case and set nameless flag.

2861 contants as a leading explicit length, followed by the string data,
2862 followed by a trailing explicit length.
2863 * eval.c (evaluate_subexp), expprint.c (print_subexp),
2864 parse.c (length_of_subexp), parse.c (prefixify_subexp):
2865 Use recorded explicit length of strings in expression elements,
2866 rather than strlen. Adjust code to skip over strings stored in
2867 expression elements, and code to access strings, to account for
2868 new leading explicit size expression element.
2869 * parse.c (length_of_subexp): Test for minimum endpos of 1, not
2870 0, to avoid negative expression element indices.
2871 * valops.c (search_struct_method): Minor whitespace change.
2872

2874
2875 * c-exp.y (yylex): Add tempbuf, tempbufindex, and tempbufsize,
2876 which together maintain a dynamically expandable static buffer
2877 for the lexer to use when translating C strings to their internal
2878 form (other future uses possible). Fix parsing of C style strings
2879 to do the normal C style input conversions of escaped character
2880 sequences.
2881 * valops.c (value_string): Remove translation of escaped
2882 character sequences, now done in C expression parser.
2883 * language.h (PRINT_LITERAL_FORM): New macro that takes character
2884 and decides if it should be printed in literal form or some other
2885 form, based on it's ASCII value and setting of sevenbit_strings.
2886 * {c-exp.y, m2-exp.y} (emit_char): Use new PRINT_LITERAL_FORM
2887 macro, change indentation style.
2888 * ch-exp.y (chill_printchar): Use new PRINT_LITERAL_FORM macro.
2889 * ch-exp.y (chill_printstr): First cut at real function instead
2890 of error stub.

2959 * remote-udi.c (udi_open): Reset vars so that user can re-run
2960 programs without leaving GDB.
2961 * (many routines): Slightly improve error handling.

3009 instructions as function_frame_info does. Expand special case of
3010 st r31,-4(r1) to be st r31,NUM(r1), since gcc can generate offsets
3011 other than -4.
3012 (pop_frame): Add 4 rather than sizeof (int) to avoid host
3013 dependence.
3014 (function_frame_info): Set frameless if the function has no frame,
3015 and set nosavedpc if the PC was not saved. Handle gcc generated
3016 stfd 31,-4(31); st 31, -12(31) correctly.
3017 (frameless_function_invocation): New second argument pcsaved; if 0
3018 return whether the function has a frame, if 1 return whether the
3019 function saved PC.

3024
3025 * infrun.c (wait_for_inferior (just before step_over_function
3026 label)): Change test for stepping into subroutine to check for the
3027 presence of line number info. This makes stuff compiled with -g1
3028 cause GDB to not lose control when stepping.
3029
3030 * symtab.c (find_pc_line): Improve code per gnu's suggestions.
3031 Improve comments as well.

3117
3118 * xcoffexec.c (vmap_symtab): fixed a bug where if a object has no
3119 member, and the stat pointer passed to vmap_symtab was NULL, the
3120 wrong vmap entries would be modified. Fixes behavior where
3121 attempting to load symbols for a module with no member would mess
3122 up already read in symbols.
3123

3132 requirement for useless 'program' argument. Clean up
3133 udi_create_inferior, and udi_load to call common download()
3134 routine. Create download routine to load remote hosts directly
3135 (with the help of BFD) so that we don't need yank.c and
3136 mini2udi.c.
3137 Fix udi_detach to call UDIDisconnect with
3138 the right arguments. Clean up udi_resume, don't assign tip_error
3139 twice. Clean up udi_wait, straighten out status codes. Make
3140 udi_kill really work.
3141

3168
3169 * m68k-stub.c: Remove ansidecl.h and the few uses of it.

3572 vaxbsd.mh, vaxult.mh (XDEPFILES): Add corelow.o whenever coredep.o
3573 appears. FIXME, these should be moved to NATDEPFILES for native
3574 use only.
3575
3576 Thu Oct 15 21:53:53 1992 K. Richard Pixley (rich@sendai.cygnus.com)
3577

3596
3597 * Makefile.in (VERSION): Roll to 4.6.8.
3598 (OBS): Put version.o first, so Makefile rebuild happens early.
3599
3600 * command.h: Publicize prototype for not_just_help_class_command.
3601 * command.c: Remove proto.
3602 * maint.c: Mark "mt" as an abbrev, to avoid duplicated help
3603 output. Move "maint info" from class info to class maintenance,
3604 and improve text.
3605 * infrun.c: Move "stop" to class_obscure, and give it a
3606 function so it will not be seen as a global help topic. FIXME,
3607 it should be possible to set these attributes independently.
3608
3609 * core.c (core_command): Make nicer error message for no core support.
3610
3611 Lint around file_ptr's (bfd's off_t's) and bfd_seek.
3612
3613 * dbxread.c (read_dbx_symtab): Use L_SET as bfd_seek arg.
3614 (elfstab_build_psymtabs): staboffset and stabstroffset args are
3615 file_ptr's.
3616 * dwarfread.c (struct dwfinfo): Convert dbfoff, lnfoff to file_ptr.
3617 (scan_compilation_units): Punt unused filename arg. dbfoff,
3618 lnoffset, and curlnoffset are file_ptr's now.
3619 (dwarf_build_psymtabs): Drop desc and filename args; use
3620 objfile. dbfoff and lnoffset are file_ptr's now.
3621 (read_ofile_symtab): foffset is now file_ptr. Use L_SET in bfd_seek.
3622 * elfread.c (struct elfinfo): dboffset and lnoffset are file_ptr's.
3623 (elf_symfile_read): Skip desc and filename args to
3624 dwarf_build_psymtabs. Pass file_ptr's to elfstab_build_psymtabs.
3625 * gdb-stabs.h: Use file_ptr rather than off_t.
3626 * mipsread.c (fixup_symtab): f_ptr is a file_ptr. Re-enable
3627 compile-time debug check that someone turned off as "unused".
3628 (read_the_mips_symtab): st_filptr is a file_ptr. Fix bfd_seek call.
3629 * symfile.h: Update dwarf_build_psymtabs and
3630 elfstab_build_psymtabs prototypes.
3631 * xcoffread.c (init_stringtab, init_lineno, xcoff_symfile_read):
3632 Use file_ptr offsets. bfd_seeks use L_SET.
3633
3634 Thu Oct 15 01:27:32 1992 Stu Grossman (grossman at cygnus.com)
3635
3636 * mips-tdep.c, mipsread.c, tm-mips.h: Get rid of ".gdbinfo."
3637 symbol. #define MIPS_EFI_SYMBOL_NAME instead. Use different
3638 value so that demangler won't be invoked. This greatly speeds up
3639 stepping.
3640 * mips-tdep.c (mips_pop_frame): Rewrite handling of
3641 linked_proc_info so that it properly deallocates the appropriate
3642 item after it is done with it instead of before.
3643 * Don't pass bogus frame pointer to create_new_frame(). Just
3644 leave it as zero so that lower level code will figure out the
3645 correct value.
3646

3776
3777 Wed Oct 7 12:24:01 1992 Ken Raeburn (raeburn@cygnus.com)

3780 program.
3781 * nindy-share/nindy.c (coffstrip): Use that pathname, instead of

3783 passed to that program.
3784
3785 * tm-nindy960.h (ADDITIONAL_OPTIONS): Use "-ser" rather than "-r",
3786 which is now used for something else. Rewrite description of
3787 associated parameters to match how gdb does it now.
3788 (ADDITIONAL_OPTION_HELP): Fix message accordingly.
3789
3790 * m68k-pinsn.c (print_insn_arg): Handle new "`" operand type.

3841 Fri Sep 4 00:34:30 1992 Per Bothner (bothner@rtl.cygnus.com)
3842
3843 A bunch of changes mostly to improve debugging of C++ programs.
3844 Specifically, the calling of inferiors methods is improved.
3845
3846 * value.h: New macros METHOD_PTR_IS_VIRTUAL,
3847 METHOD_PTR_FROM_VOFFSET, METHOD_PTR_TO_VOFFSET to partially
3848 hide the implementation details of pointer-to-method objects.
3849 How to tell if the pointer points to a virtual method is
3850 still very dependent on the particular compiler, but this
3851 should make it easier to find the places to change.
3852 * eval.c (evaluate_subexp [case OP_FUNCALL]), valprint.c
3853 (val_print [case TYPE_CODE_PTR]): Use the new METHOD_PTR_*
3854 macros, instead of a hard-wired-in code that incorrectly
3855 assumed a no-longerused representation of pointer-to-method
3856 values. And otherwise fix the relevant bit-rotted code.
3857
3858 * valprint.c (type_print_base [case TYPE_CODE_STRUCT]):
3859 If there are both fields and methods, put a space between.
3860
3861 * stabsread.c (read_struct_type): Fix bug in handling of
3862 GNU C++ anonymous type (indicated by CPLUS_MARKER followed
3863 by '_'). (It used to prematurely exit the loop reading in
3864 the fields, so it would think it should start reading
3865 methods while still in the fields. This could crash gdb
3866 given a gcc that can emit nested type information.)
3867
3868 * valops.c (search_struct_method): Pass 'this' value by
3869 reference instead of by value. This provides a more
3870 consistent interface through a recursive search where the
3871 "bottom" functions may need to adjust offsets (due to multiple
3872 inheritance).
3873 * valops.c, value.h, values.c: Pass extra parameters to
3874 value_fn_field and value_virtual_fn_field so we can
3875 correctly adjust offset for multiple inheritance.
3876 * eval.c (evaluate_subexp [case OP_FUNCALL]): Simplify
3877 virtual function calls by using value_virtual_fn_field().
3878 * values.c: New function baseclass_offset, derived from
3879 baseclass_addr (which perhaps can be made obsolete?).
3880 It returns an offset rather than an address. This is a
3881 cleaner interface since it doesn't mess around allocating
3882 new values.
3883 * valops.c (search_struct_method): Use baseclass_offset
3884 rather than baseclass_addr.
3885
3886 Mon Oct 5 16:02:04 1992 Stu Grossman (grossman at cygnus.com)
3887
3888 * Makefile.in: Re-install 29K/UDI stuff.
3889 * remote-udi.c (udi_resume): Clean up.
3890 * (udi_wait): Rewrite, leave out bugs.
3891 * Add debugging code to print out all register fetches and stores.
3892 * Straighten out target_ops.
3893 * tm-29k.h (DUMMY_FRAME_RSIZE): Pad out to doubleword.
3894
3895 Mon Oct 5 09:46:44 1992 Ian Lance Taylor (ian@cygnus.com)
3896
3897 * remote-udi.c (udi_create_inferior): run with no arguments should
3898 not pass the program name as an argument, since the UDI code
3899 already handles that.
3900 (udi_load): get the symbols from prog_name, not arg_string (the
3901 load command should really use arg_string as the program name, not
3902 prog_name, but at least the run command works now).
3903
3904 * munch: HP9000/300 nm puts an extra space between T and symbol
3905 name.
3906
3907 * config/irix4.mh: added -lsun to XM_CLIBS to get RPC functions
3908 needed for vxworks targets.
3909
3910 Fri Oct 2 22:04:42 1992 John Gilmore (gnu@cygnus.com)
3911
3912 * am29k-tdep.c (_initialize_29k): Make it possible for the
3913 user to set and query the address where function calls into the
3914 inferior write a small scratch routine. `set call_scratch_address'
3915 * inferior.h (PC_IN_CALL_DUMMY): Fix fencepost error.
3916 * remote.c (remote_prepare_to_store): Only fetch regs if they are
3917 not already cached validly.
3918
3919 Thu Oct 1 14:36:42 1992 K. Richard Pixley (rich@sendai.cygnus.com)

3951 * dwarfread.c (basicdieinfo): Use dbsize to check for oversize
3952 DIEs as well as the current check for undersize DIEs. This helps
3953 to gracefully detect and reject corrupted DIE information.

3964 (help_cmd): Tell user the command is hooked, if it is.
3965 (lookup_cmd_1): Abbreviations return the original command
3966 instead of themselves, so that hooks on the original cmd will be
3967 run.
3968 * defs.h (enum command_class): Add class_pseudo and comments.
3969 * gdbcmd.h (execute_user_command): Add prototype.

4389 Tue Sep 15 01:18:50 1992 John Gilmore (gnu@cygnus.com)
4390
4391 Preliminary cleanup for splitting host/native/target.
4392
4393 * infptrace.c (child_resume): Don't deal with NO_SINGLE_STEP
4394 here; it is dealt with at a gdb-target-independent level.
4395 * rs6000-tdep.c (single_step): Don't call ptrace, we are a
4396 high toned routine. Fix return type to void.
4397 * tm-rs6000.h (AIX_BUGGY_PTRACE_CALL): Zap, we think we fixed it.
4398 Rich and I believe the "real problem" was that both single_step
4399 and target_resume were issuing PT_CONTINUE calls. This would
4400 cause the second PT_CONTINUE to sometimes fail because the process
4401 was already running.
4402 * infptrace.c (child_resume): Remove AIX_BUGGY_PTRACE_CALL kludge.
4403
4404 Mon Sep 14 19:20:43 1992 Stu Grossman (grossman at cygnus.com)
4405
4406 * energize.c (pty_to_kernel): Must check for EAGAIN as
4407 termination condition.
4408 (full_filename): Don't prepend dirname if filename begins with /.
4409 (breakpoint_notify, kernel_dispatch): Deal with DynamicLoad
4410 messages properly!!
4411 (getpty (NCR)): Lotsa bug fixes...
4412 (kernel_dispatch (case StopRType)): Use kill() instead of
4413 killpg() so we can deal with losing systems...
4414 (wait_for_events): Work around NCR select() lossage. It doesn't
4415 zero out readfds when select() returns zero.
4416 (energize_initialize): Use I_SETSIG to get SIGIO interrupts. Use
4417 getcwd() instead of getwd() (NCR getwd() seg faults).
4418 (energize_wait): Use sigaction() for NCR. Their version of signal()
4419 is unreliable by default.
4420
4421 * procfs.c (proc_wait): Call print_sys_errmsg() if we get an
4422 error from PIOCSWSTOP.
4423
4424 * breakpoint.c, core.c, exec.c, language.c, main.c, printcmd.c,
4425 symfile.c, target.c, valprint.c: Use _filtered form of *printf.
4426 defs.h, utils.c: Make vfprintf_filtered global.
4427
4428 * energize.c (send_location): New routine to consolidate all
4429 places where we must notify kernel of where the given pc is.
4430 (cplus_demangle): Put single-quotes around demangled names.
4431 (energize_call_command): Call send_location() after doing up,
4432 down, and frame commands.
4433
4434 Fri Sep 11 18:28:28 1992 Roland H. Pesch (pesch@fowanton.cygnus.com)
4435
4436 * doc/gdb.texinfo, doc/gdbinv-m.m4.in, doc/gdbinv-s.m4.in: first
4437 pass at doc for two new remote targets---29K using UDI, and Tandem
4438 ST2000 using STDBUG.
4439
4440 * doc/all.m4, doc/none.m4: new m4 switch, _ST2000__
4441
4442 * doc/all.m4: turn on H8/300 stuff for generic manual
4443
4444 * doc/gdbinv-s.m4.in: remove text on special procedures to continue
4445 after explicit call to breakpoint() in serial stubs.
4446
4447 Fri Sep 11 01:34:25 1992 John Gilmore (gnu@sphagnum.cygnus.com)
4448
4449 * mipsread.c: Clean up some white space.
4450 (parse_symbol): Handle stEnd of stFile.
4451 (parse_partial_symbols): Remove old #if 0'd code. Handle stLocal.

4454 store_inferior_registers): Replace unexplained numbers
4455 with manifest constants from a DECstation header file.
4456 * xm-mips.h (KERNEL_U_ADDR): Get from <machine/param.h>.
4457 (REGISTER_U_ADDR): Fix up for Ultrix 4.2.
4458
4459 * tm-tahoe.h, xm-tahoe.h (KERNEL_U_ADDR): Move macro to xm-tahoe.h.
4460
4461 * stack.c (_initialize_stack): "dow" should be a valid abbreviation
4462 for "down". Suggested by Richard Stallman.
4463
4464 Thu Sep 10 15:26:07 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4465
4466 * remote-vx.c: Rename realloc for inclusion of rpc/rpc.h, to avoid
4467 redeclaration bug on SunOS 4.
4468
4469 Wed Sep 9 17:36:53 1992 John Gilmore (gnu@cygnus.com)
4470
4471 * i386-stub.c, sparc-stub.c (getpacket): Actually check checksums.

4479
4480 Removed a large number of changes inserted by Per Bothner
4481 for C++ support. These will go back in when they've been
4482 examined.
4483
4484 Tue Sep 8 21:05:18 1992 Stu Grossman (grossman at cygnus.com)
4485
4486 * serial.h: Fix prototye for serial_raw().
4487 * ser-bsd.c, ser-termios.c: Fix args for serial_open() &
4488 serial_write() to match prototypes.
4489 * remote-st2000.c (get_reg_name): Make *p be const.
4490
4491 Tue Sep 8 17:24:52 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4492
4493 * remote-nindy.c (nindy_fetch_registers): Make return type void,
4494 to agree with target structure field type.
4495 (nindy_store_registers): Ditto.
4496
4497 * Makefile (OPCODES): New var, pointing to opcodes library.
4498 (CLIBS, CDEPS): Include it.

4501 Tue Sep 8 15:22:06 1992 Stu Grossman (grossman at cygnus.com)
4502
4503 * a68v-xdep.c (store_inferior_registers): declare as void.
4504 * infptrace.c: HP/Apollos have ptrace.h in the wrong place.
4505 * remote-st2000.c: Massive changes to use new serial package.
4506 Also added 'connect' command to transparantly connect to serial
4507 port.
4508 * ser-termios.c: Big cleanup, use nicer coding conventions.
4509 * ser-bsd.c: New module, serial stuff for BSD systems.
4510 * serial.h: Define struct ttystate properly using HAVE_TERMIO.
4511 * xm-apollo68b.h: #define PTRACE_IN_WRONG_PLACE...
4512
4513 Fri Sep 4 18:53:57 1992 Roland H. Pesch (pesch@fowanton.cygnus.com)
4514
4515 * doc/gdb.texinfo: fix shameful error of agreement reported by
4516 jimb@occs.cs.oberlin.edu (Jim Blandy)
4517 * doc/gdb.texinfo: remove old partial discussion of remote serial
4518 protocol (via serial debug stubs)
4519 * doc/gdbinv-m.m4.in, doc/gdbinv-s.m4.in: new section discussing
4520 use of serial debug stubs
4521
4522 Fri Sep 4 00:34:30 1992 Per Bothner (bothner@rtl.cygnus.com)
4523
4524 * symfile.h: Declaration of set_demangling_style() moved
4525 here from demangle.h (which is now in ../include).
4526 * i386-xdep.c: Update comment.
4527
4528 Thu Sep 3 13:44:46 1992 K. Richard Pixley (rich@sendai.cygnus.com)
4529
4530 * symtab.c (completion_list_add_symbol): restructured to optimize
4531 for time. First clip names that cannot match. Then clip any
4532 names we've already considered. Drop a redundant strncpy. Drop
4533 a redundant malloc and associated free for demangled names.
4534
4535 Thu Sep 3 09:17:05 1992 Stu Grossman (grossman at cygnus.com)
4536

4538 * configure.in: Add host m68k-apollo*-bsd*.
4539 * demangle.c (struct demanglers): Use enum instead of constant
4540 value to keep braindamaged HP/Apollo compiler happy.
4541
4542 Wed Sep 2 20:45:31 1992 Per Bothner (bothner@rtl.cygnus.com)
4543
4544 * utils.c (strcmp_iw): Add a hack to allow "FOO(ARGS)" to
4545 match "FOO". This allows 'break Foo' to work when Foo is
4546 a mangled C++ function. (See comment before function.)
4547

4556
4557 * tm-vx68.h, tm-es1800.h: Use tm-68k.h rather than tm-sun3.h.

4580 * config/sun4.{mh,mt}: Remove (use identical sun4os4.*).
4581
4582 Wed Sep 2 00:10:43 1992 John Gilmore (gnu@cygnus.com)
4583
4584 * configure.in (*-*-sunos*): Use trailing * to match all
4585 sub-variants of SunOS, e.g. sunos4* to match sunos4.1.1.
4586 (sparc-*-sunos3): Remove host & target. Sunos3 never shipped
4587 in production on Sun-4.
4588 ({a29k,i[34]86,i960}-*-elf): Add targets, equivalent to coff.
4589 (m68k-*-{aout,coff,elf}): Add targets, w/new config and tm files.

4593 config/sparc-noun.mt: New target configs for embedded.
4594 * config/sun4os3.{mh,mt}: Remove, never existed in production.
4595

4597 target definitions for embedded with and without underlines on
4598 identifiers.
4599
4600 * tm-sparc.h, tm-sun2.h, tm-sun3.h: Delete NAMES_HAVE_UNDERSCORE:
4601 not a parameter of the CPU, but of the development environment.
4602 * tm-es1800.h, tm-sunos.h, tm-vx68.h: Add NAMES_HAVE_UNDERSCORE.
4603
4604 Tue Sep 1 17:31:45 1992 John Gilmore (gnu@cygnus.com)
4605
4606 * breakpoint.c (breakpoint_re_set): Avoid setting source symtab
4607 (which involves reading in main's symtab) if we have no breakpoints.
4608
4609 Mon Aug 31 13:47:45 1992 Fred Fish (fnf@cygnus.com)
4610

4616 synthesize a typedef for C++ classes, structs, unions, and
4617 enumerations.
4618 * dwarfread.c (read_structure_scope): Synthesize typedefs
4619 for C++ classes, structs and unions.

4621 C++ enumerations.
4622 * dwarfread.c (read_file_scope): Call set_cu_language to
4623 record language for current compilation unit. After symtab

4626 scan_partial_symbols, new_symbol): Recognize TAG_class_type.
4627 * dwarfread.c (add_partial_symbol): Synthesize partial symbol
4628 typedefs for C++ classes, structs, unions, and enumerations.
4629 * dwarfread.c (scan_compilation_units): Call set_cu_language
4630 to record language for current compilation unit.
4631 * dwarfread.c (scan_partial_symbols): Call add_enum_psymbol here
4632 for TAG_enumeration_types, rather than in add_partial_symbol.
4633 * dwarfread.c (add_partial_symbol): Combine TAG_enumeration_type
4634 case with class, struct, and union type cases, now that they are
4635 the same. Remove tests for non-NULL name attributes, now done
4636 by callers.
4637 * gdbtypes.h (TYPE_CODE_CLASS): Add type for C++ classes, but
4638 treat as alias for TYPE_CODE_STRUCT for now.
4639

4648 (supply_gregset, fill_gregset, supply_fpregset, fill_fpregset):
4649 Use "regi" for local indexing through register numbers, reserving
4650 "regno" for the name of a specific register passed as an input
4651 parameter. Fix bug propagated through all versions that sometimes
4652 used regno as an index when it should have been regi, thus using
4653 -1 as an index in some cases.
4654
4655 Sun Aug 30 18:15:17 1992 Per Bothner (bothner@rtl.cygnus.com)
4656

4689 add_text_to_loadinfo, find_toc_address): Move from xdep file.
4690 Use CORE_ADDRs. Change identifiers to lowercase.
4691
4692 * rs6000-xdep.c: Make whole file conditional on native RS/6000,
4693 supplying dummy routines if non-native. Add prototype for
4694 static exec_one_dummy_insn. Move a mess of functions to

4703
4704 * vx-share/README, nindy-share/README: New files describing

4716 * config/nindy960.mt: Remove useless MT_CFLAGS setting.
4717 * config/i386aout.mt: Use tm-i386v.h, not tm-i386v-g.h.
4718

4730
4731 * cplus-dem.c: Reorder args to most local functions to make them
4732 follow the consistent pattern of struct work_stuff pointer first,
4733 followed by pointer into string being demangled, followed by
4734 pointer to the string where the result is being stored, followed
4735 by other args. Also generally replace most variables of name
4736 "type" with "mangled" for consistency. They all pointed to the
4737 same string but half were one name and half the other.
4738 * cplus-dem.c (LONGERNAMES): Remove #ifndef's.
4739 * cplus-dem.c (demangle_qualified): Rewrite to clean up and allow
4740 use whenever a qualified name is being demangled.
4741 * cplus-dem.c (do_type): Qualified names are treated similarly
4742 to fundamental types, not as modifiers of fundamental types.

4752
4753 * infrun.c (handle_command): Rewrite to allow multiple signal
4754 numbers, signal number ranges, and to recognize "all" to mean all
4755 signals except those used by the debugger.
4756 * infrun.c (SET_SIGS, UNSET_SIGS): Macros used in handle_command
4757 to set or reset actions for specific signals.
4758

4771 allocate space for the type structure itself.
4772 * coffread.c (patch_type, coff_read_struct_type,
4773 coff_read_enum_type): Use TYPE_ALLOC.
4774 * dwarfread.c (struct_type): Use TYPE_ALLOC.

4789 * eval.c (evaluate_subexp): Report error when attempting to
4790 evaluate subscript for types without a target type, rather
4791 than dumping core by using the NULL pointer.

4793 and current_source_line when discarding symbol table.
4794
4795 Sat Aug 22 22:33:20 1992 John Gilmore (gnu@cygnus.com)

4803
4804 * remote.c (remote_open): Fix baud rate setting to make -b flag
4805 work. (remote_wait): Change 'T' message parser to deal with new
4806 improved format which allows stub to send an arbitrary bunch of
4807 registers.
4808 * sparc-stub.c: General cleanups. (trap_low, handle_exception):
4809 make all this re-entrant by storing all state on the stack. Clean

4898 * am29k-tdep.c: Lint from DECstation compiler.
4899 * mem-break.c: Restore test of BREAKPOINT size that Fred removed.
4900 As the man page says, "Sometimes you just can't get lint to shut

4902 shut up about.
4903 * mips-xdep.c: Revise stubbing-out of code until Rich cleans
4904 it up over the next few weeks. Make mips x 29k build.

4906 (FIX_CALL_DUMMY): Comment in the patching of the breakpoint,
4907 but leave it as a comment because the breakpoint instruction
4908 is not easily accessible at this moment (it's static, and if
4909 we define one here, it goes into every file compiled).
4910
4911 Mon Aug 10 22:27:19 1992 Fred Fish (fnf@cygnus.com)
4912
4913 * Makefile.in (VERSION): Bump to 4.6.3.

4927 * dwarfread.c (completedieinfo): Set has_at_byte_size when
4928 an AT_byte_size attribute is seen.

4942 * source.c (find_source_lines): if LSEEK_NOT_LINEAR is defined
4943 then work out the lseek positions of newlines by running through
4944 the file and `tell'ing. This makes source file listing work on
4945 OS's where the relationship between physical position in file and
4946 canonical position is indeterminate, eg VMS and DOS.

5185 producers. Set demangling style based on producer string if
5186 current style is auto. (Note: this feature currently disabled.)
5187 * config/ncr3000.mt (DEMANGLE_OPTS): Remove.
5188
5189 Sat Jul 11 18:23:58 1992 John Gilmore (gnu at cygnus.com)
5190
5191 * config/sun4sol2.mh: Remove -xs flag, default INSTALL to cp.
5192
5193 Fri Jul 10 13:58:34 1992 Per Bothner (bothner@rtl.cygnus.com)
5194
5195 * gdbtypes.c, gdbtypes.h: New function lookup_signed_typename.
5196 * c-exp.y: Call lookup_signed_typename() after seeing
5197 "signed". This handles "signed char" correctly.
5198 * c-exp.y: Recognize (but ignore) 'const' and 'volatile'
5199 keywords before a type specifier.
5200
5201 Fri Jul 10 10:19:52 1992 Fred Fish (fnf@cygnus.com)
5202
5203 * command.c (lookup_cmd_1): Clarify descriptive comments.
5204 * gdbcmd.h (maintenanceprintlist): Add declaration.
5205 * main.c (maintenanceprintlist): Add definition.
5206 * main.c (gdb_completer_command_word_break_characters): Add.
5207 * main.c (symbol_completion_function): Switch completer word
5208 break character sets dynamically, based on whether completion is
5209 being done on commands or on something else.
5210 * main.c (initialize_cmd_lists): Init maintenanceprintlist.
5211 * maint.c: Include demangle.h.
5212 * maint.c (maintenance_demangle): New function.
5213 * maint.c (maintenance_print_command): New function.
5214 * maint.c (_initialize_maint_cmds): Reorganize some commands
5215 under new maintenance print subcommand.
5216
5217 Thu Jul 9 19:05:27 1992 Per Bothner (bothner@rtl.cygnus.com)
5218
5219 * gdbtypes.c (lookup_struct_elt_type): If the input type is
5220 TYPE_CODE_PTR or TYPE_CODE_REF, dereference it to get the
5221 target type. Otherwise, 'whatis this.field' wouldn't work,
5222 which would be inconsistent, since 'print this.field' works.
5223 * buildsym.c (read_struct_type, read_enum_type): Clear
5224 TYPE_FLAG_STUB flag.
5225 * buildsym.c (cleanup_undefined_types): Don't rely on a
5226 flawed "Reasonable test to see if" a type has been defined
5227 since it was referred to; now we can just see if the
5228 TYPE_FLAG_STUB flag has been cleared.
5229 * valprint.c (print_type_base): Emit public/protected/private
5230 labels for methods as well as fields. Also, indent these labels
5231 2 spaces instead of 4, for a more conventional "look".
5232 * symtab.c (gdb_mangle_name): Undo Fred's change, unless
5233 GCC_MANGLE_BUG is defined. Also, handle destructors specially.
5234 * gcc.patch: New file. Contains patch for gcc (so people
5235 with gdb-2.2.x won't have to wait for a new gcc release).
5236
5237 Thu Jul 9 18:44:26 1992 Ken Raeburn (raeburn@cygnus.com)
5238
5239 * i960-pinsn.c (mem): Variables reg[123] should point to CONST.
5240 (print_addr): Call print_address to show symbolic version as well.
5241
5242 * remote-vx.c (vx_kill): Don't look for arguments; they aren't
5243 being passed.
5244 (vx_read_register): Declare inferior_fp_regs. Delete code for
5245 copying "inferior_registers" around; the values are already in var
5246 "registers". Use correct size for register set.
5247
5248 * remote-vx.c (vx_write_register): Don't try writing FP regs; the
5249 target doesn't support it.
5250 (vx_read_register): Don't try reading them either.
5251
5252 * tm-i960.h (IP_REGNUM): Move to end of non-FP list, since the
5253 VxWorks back end reads them in one contiguous set except for this
5254 one.
5255 (register_names): Change "pc" to "pcw" to avoid confusion printing
5256 "$pc".
5257 * tm-vx960.h (PC_REGNUM): Use RIP_REGNUM, since that's where we
5258 find the PC under VxWorks.
5259
5260 Wed Jul 8 21:34:30 1992 Fred Fish (fnf@cygnus.com)
5261
5262 * dwarfread.c (alloc_utype, decode_subscr_data): Call alloc_type
5263 to create new blank types, instead of handcrafting them.
5264 * defs.h (printfi_filtered): Add prototype.
5265 * utils.c (printfi_filtered): New function.
5266 * gdbtypes.c (recursive_dump_type): Use printfi_filtered to
5267 to simplify the code. Other cleanups.
5268 * gdbtypes.c (check_stub_method): Demangle using DMGL_ANSI.
5269 * gdbtypes.h (struct cplus_struct_type): Add comments describing
5270 use of various fields.
5271 * gdbtypes.c (print_bit_vector, print_cplus_stuff): New functions.
5272 * c-exp.y (%token): Add CLASS as a token for C++, add grammar
5273 production that currently treats it exactly the same as STRUCT.
5274 * c-exp.y (yylex): Recognize "class" as token CLASS.
5275 * symtab.c (gdb_mangle_name): Rewrite to match current g++ stabs.
5276 * symtab.c (decode_line_1): Fix to pass quoted args on down to
5277 general symbol handling code. Call cplus_mangle_opname with
5278 DMGL_ANSI.
5279 * symtab.c (decode_line_2): Print demangled function names in
5280 breakpoint menus, instead of just file and line number.
5281 * symtab.c (name_match): Call cplus_demangle with DMGL_ANSI.
5282 * valprint.c (type_print_base): Print "class" for C++ classes,
5283 rather than "struct". Print section labels for public, protected
5284 and private members of C++ classes.
5285 * values.c: Include demangle.h.
5286 * values.c (value_headof): Call cplus_demangle with DMGL_ANSI.
5287
5288 Wed Jul 8 17:23:07 1992 Stu Grossman (grossman at cygnus.com)
5289
5290 * Makefile.in (VERSION): Update to 4.5.8.
5291
5292 Wed Jul 8 00:11:02 1992 Stu Grossman (grossman at cygnus.com)
5293
5294 * dbxread.c (dbx_symfile_init): Init stab_section_info to NULL to
5295 prevent crashes when examining cross-targets.
5296 * dbxread.c (process_one_symbol): Include directory name when
5297 calling start_subfile for SOL & BINCL symbols. This allows gdb to
5298 find include files, and yacc/lex sources when the cwd doesn't match
5299 that in which the object was compiled.
5300 * objfiles.h (ALL_MSYMBOLS): Don't seg fault when there are no
5301 msymbols.
5302 * symtab.c (lookup_symtab_1): Rewrite. It now handles include
5303 files.
5304
5305 Tue Jul 7 09:00:42 1992 Fred Fish (fnf@cygnus.com)
5306
5307 * maint.c (maintenance_command, maintenance_info_command):
5308 Install with allow_unknown as 0 and call help_list to show
5309 list of possibilities when no subcommand is specified.
5310
5311 Tue Jul 7 00:20:29 1992 Fred Fish (fnf@cygnus.com)
5312
5313 * configure.in: Add m68k-ericsson-*.
5314 * remote-es1800.c, tm-es1800.h, config/es1800.mt: New files.
5315
5316 Sun Jul 5 17:17:16 1992 Fred Fish (fnf@cygnus.com)
5317
5318 * maint.c: New file.
5319 * Makefile.in (SFILES_MAINDIR): Add new file maint.c.
5320 * Makefile.in (OBS): Add new file maint.o.
5321 * defs.h (command_class): Add class_maintenance.
5322 * defs.h (MAINTENANCE_CMDS): Default to including maintenance
5323 commands. Allow for them (and other nonessential parts of gdb)
5324 to be selectively left out under special circumstances.
5325 * gdbtypes.c (recursive_dump_type): New function; supports
5326 maintenance print-type command.
5327 * gdbtypes.h (recursive_dump_type, maintenance_print_type):
5328 Add prototypes.
5329 * main.c (maintenancelist, maintenanceinfolist): Add maintenance
5330 command lists.

5333 setchecklist, showchecklist, maintenancelist, and maintenanceinfolist.
5334 * printcmd.c (maintenance_print_type): New maintenance cmd.
5335 * valprint.c (setprintlist, showprintlist): Move to main.c, as
5336 implied by comment that all cmd lists are owned by main.c.
5337 * infcmd.c (unsetlist): Move to main.c, as implied by comment
5338 that all cmd lists are owned by main.c.
5339 * language.c (setchecklist, showchecklist): Move to main.c, as
5340 implied by comment that all cmd lists are owned by main.c
5341 * breakpoint.c (enablelist, enablebreaklist, disablelist, cmdlist,
5342 deletelist): Remove redundant declarations (also in gdbcmd.h).
5343 * symmisc.c (printsyms_command): Now maintenance_print_symbols.
5344 * symmisc.c (printmsyms_command): Now maintenance_print_msymbols.
5345 * symmisc.c (printpsyms_command): Now maintenance_print_psymbols.
5346 * symmisc.c (printobjfiles_command): Now maintenance_print_objfiles.
5347 * symtab.h (maintenance_print_symbols, maintenance_print_psymbols,
5348 maintenance_print_msymbols, maintenance_print_objfiles):
5349 Add prototypes.
5350 * symmisc.c (printsyms_command, printpsyms_command,
5351 printmsyms_command, printobjfiles_command): Removed from
5352 _initialize_symmisc.
5353 * main.c (dump_me_command): Moved to maint.c and renamed to
5354 maintenance_dump_me.
5355 * breakpoint.c (all_breakpoints_info): Rename to
5356 maintenance_info_breakpoints.
5357 * breakpoint.c (_initialize_breakpoint): Convert add_info of
5358 all_breakpoints_info to add maintenance_info_breakpoints to the
5359 maintenanceinfolist instead.
5360 main.c (initialize_main): Set up maintenance class commands.
5361
5362 Sun Jul 5 11:03:53 1992 Stu Grossman (grossman at cygnus.com)
5363
5364 * energize-patches: Fix minor problems with building energize lib.
5365
5366 * energize-patches: Change names of all cadillac procedure calls
5367 to be energize procedure calls. Simplify many hooks by moving
5368 tests energize.c. Configure energize, and build it automatically now.
5369
5370 Sun Jul 5 09:43:28 1992 Fred Fish (fnf@cygnus.com)
5371
5372 * Makefile.in (VERSION): Bump to 4.5.7.
5373 * cplus-dem.c (demangle_args): Validate index for previously
5374 seen type to guard against bogus values from malformed manglings.
5375 * valops.c (value_struct_elt_for_reference): Guard against
5376 blindly using NULL return value from lookup_symbol.
5377
5378 Sun Jul 5 09:46:43 1992 Stu Grossman (grossman at cygnus.com)
5379
5380 * cadillac.c, cadillac-patches: Rename to energize.c and
5381 energize-patches. Change all routines and variables named
5382 'cadillac*' to 'energize*'. Create new file called energize.h to
5383 hold all interface declarations.
5384
5385 * deblib/connection/*: Move all of this stuff into energize/, but
5386 delete unneeded files.
5387
5388 Sun Jul 5 03:06:39 1992 John Gilmore (gnu at cygnus.com)
5389
5390 * tm-sysv4.h (NAMES_HAVE_UNDERSCORE): SVR4 systems don't.
5391
5392 * buildsym.c (finish_block): Fix thinko `inner block' complaints.
5393 * dbxread.c (process_one_symbol): Parse N_OPT "gcc2_compiled.".
5394 * procfs.c (proc_set_exec_trap): Set run-on-last-close flag on
5395 child processes, to avoid dead ones "hanging around" after GDB exits.
5396 (attach): Always stop the process if it needs it. Set RLC flag
5397 when attaching running processes, so it will continue if we detach
5398 it, quit, or are killed.
5399 (detach): Clear faults and set RLC flag to make process run
5400 when we close it.
5401 (open_proc_file): New `mode' argument for O_RDONLY or O_RDWR.
5402 Callers changed.
5403 (info_proc): Open process O_RDONLY, so we can see any process,
5404 even those controlled by debuggers.
5405 * tm-sun4sol2.h (SUN_FIXED_LBRAC_BUG): They did (in Sol 2).
5406
5407 Sat Jul 4 03:43:38 1992 John Gilmore (gnu at cygnus.com)
5408
5409 Relocate symbols using an array of section_offsets, rather than a
5410 single `addr' or `offset'. This makes Solaris-2 support work, and
5411 permits better VxWorks (and maybe xcoff) support later.
5412
5413 * symtab.h (struct section_offsets): New structure for keeping
5414 a set of offsets, rather than a single one.
5415 (struct objfile): Replace addr with section_offsets member.
5416 * symfile.h: Add sym_offsets to struct sym_fns. Conforming changes.
5417 * gdb-stabs.h: New include file with `symbol type specific'
5418 parameters for psymtabs and objfiles.
5419 * Makefile.in (HFILES): Add gdb-stabs.h.
5420 * buildsym.h (start_psymtab, process_one_symbol): Fix prototypes.
5421 * coffread.c: Conforming changes. Fake offset array always 0.
5422 * dbxread.c: Conforming changes.
5423 (struct dbx_symfile_info): Move to gdb-stabs.h.
5424 (start_psymtab): Call elfstab_offset_sections to calculate good
5425 offsets for this source file, based on the ELF symbol table info.
5426 (read_ofile_symtab): Yank N_CATCH, which is dead.
5427 (process_one_symbol, N_CATCH): Yank.
5428 (", N_FUN, N_FNAME, N_FN, N_FN_SEQ, N_SO, N_SOL, N_ENTRY):
5429 Relocate with SECT_OFF_TEXT.
5430 (", N_STSYM, N_LCSYM, N_ROSYM): Grope around in the stab string
5431 to distinguish relocatable from absolute symbols. Then, if not
5432 absolute, do:
5433 (", N_STSYM, N_DSLINE): SECT_OFF_DATA.
5434 (", N_LCSYM, N_BSLINE): SECT_OFF_BSS.
5435 (", N_ROSYM): SECT_OFF_RODATA.
5436 (elfstab_build_psymtabs): Caller has allocated dbx_symfile_info.
5437 (dbx_symfile_offsets): Add to translate addr to offset.
5438 * dwarfread.c: Conforming changes. Single offset currently used.
5439 * elfread.c: Add various complaints about elf/stab stuff.
5440 #include gdb-stabs.h. Conforming changes, using a single offset.
5441 (elf_symtab_read): Record info from BSF_FILE symbols, and local
5442 variables called "Bbss.bss", "Ddata.data", and "Drodata.rodata",
5443 for later use in building psymtabs.
5444 (elf_symfile_read): Allocate dbx_symfile_info here, to keep
5445 the info collected in elf_symtab_read. Cleanup calls free_elfinfo.
5446 (free_elfinfo): New fn, frees all chained stab_section_infos
5447 in an objfile, and zaps the start-of-chain pointer.
5448 (elfstab_offset_sections): New fn, looks in stab_section_info
5449 chain to determine section bases to relocate a psymtab's worth
5450 of symbols, as they are being read.
5451 * mipsread.c: Conforming changes. Stabs-reading will relocate
5452 using one offset. MIPS-reading will not relocate at all.
5453 * partial-stab.h: Relocate different symbol types using different
5454 offsets from section_offsets.
5455 * symfile.c: Conforming changes.
5456 (find_lowest_section): Unused function to use later
5457 to free us from the Tyranny of the Text Section.
5458 (syms_from_objfile): Translate absolute arg ADDR to offsets used
5459 in all lower layers of symbol reading. Call format-specific
5460 sym_offsets function to initialize offsets for high speed symbol
5461 reading.
5462 (symbol_file_add): Call reinit_frame_cache so callers don't have to.
5463 (symbol_file_command, add_symbol_file_command): Callers changed.
5464 * symmisc.c (dump_psymtab): Print new relocation parameters.
5465 * xcoffread.c: Corresponding changes.
5466
5467 * buildsym.c: Tidy innerblock_complaint and blockvector_complaint.
5468 * main.c (main): Read the $HOME/.gdbinit file before processing
5469 the argv arguments (e.g. reading symbol files or core
5470 files). This allows global parameters to be set, which will apply
5471 during the symbol reading. The ./.gdbinit is still read after
5472 argv processing.
5473 * symtab.c (list_symbols): `i variables' shouldn't show enum values.
5474 * xcoffexec.c: Clean up quote inside comment.
5475
5476 Fri Jul 3 20:18:26 1992 Fred Fish (fnf@cygnus.com)
5477
5478 * breakpoint.c, buildsym.c, c-exp.y, coffread.c, command.c,
5479 core.c, cplus-dem.c, dbxread.c, dwarfread.c, elfread.c, environ.c,
5480 eval.c, findvar.c, gdbtypes.c, hppabsd-tdep.c, hppahpux-tdep.c,

5485 tm-i386v.h, tm-sparc.h, utils.c, valarith.c, valops.c, valprint.c,
5486 values.c, xcoffread.c:
5487 Remove "(void)" casts from function calls where the return value
5488 is ignored, in accordance with GNU coding standards.
5489
5490 Fri Jul 3 00:00:49 1992 John Gilmore (gnu at cygnus.com)
5491
5492 * dbxread.c (process_one_symbol): Ignore N_MAIN, N_ENDM for Solaris.
5493 * partial-stab.h: Ignore N_ENDM.
5494 * elfread.c (elf_symtab_read): Ignore symbols that don't have a
5495 CODE or DATA section attachment. This eliminates a lot of random
5496 values from shared libraries, which screw up the ordinary symbols
5497 in the address ranges they happen to overlap.
5498 * buildsym.c (define_symbol): Eliminate special tests
5499 for function types; move into "function" cases in switch statement.
5500 (define_symbol: 'f', 'F', 'P'): Process all parameter types
5501 in case they define new type numbers. But ignore them (FIXME).
5502 ('k', 'B'): Ignore const and volatile if we see them (FIXME).
5503 (read_sun_builtin_type): Add commentary.
5504
5505 Wed Jul 1 00:47:02 1992 david d `zoo' zuhn (zoo at cirdan.cygnus.com)

5511 * tm-mips.h (GDB_TARGET_IS_MIPS): Define for mips-xdep.c.
5512 (READ_MIPS_FORMAT, COFF_FORMAT): Remove, unused now.
5513 * mips-xdep.c: Remove most include files (unused, caused errs).
5514 (fetch_core_registers): Use right parameters in dummy fn.
5515
5516 Mon Jun 29 18:30:57 1992 John Gilmore (gnu at cygnus.com)
5517
5518 * buildsym.c (scan_file_globals): Beware the null file.
5519 Fix from Jim Williams.
5520
5521 * stack.c (return_command): Evaluate expression *before* popping
5522 off the stack frames! Fix inspired by Jim Williams.
5523 (up_silently_command, down_silently_command): No sel frame is error.
5524
5525 * defs.h (memcpy, memset): Conditionalize decls on
5526 #ifndef MEM_FNS_DECLARED, since DECstation differs.
5527 (alloca): Break out the STDC and non-STDC alloca cases, to make
5528 it work on old preprocessors as well as "picky ANSI" ones.
5529 * xm-mips.h (memcpy, memset): Declare, and set MEM_FNS_DECLARED.
5530
5531 * mips-tdep.c (heuristic_proc_start): Zero arg produces zero.
5532 * utils.c (fputs_demangled): Rename SLOP since DECstation system
5533 header files define it!
5534
5535 * tm-29k.h (BREAKPOINT): Allow it to be overridden with -D.
5536
5537 Mon Jun 29 16:30:25 1992 Fred Fish (fnf@cygnus.com)
5538
5539 * dbxread.c, i386-pinsn.c, i386-tdep.c, regex.c, solib.c, symmisc.c,
5540 symtab.h, tm-i386v4.h, valprint.c, values.c: Lint.
5541 * breakpoint.c, c-exp.y, coffread.c, command.c, environ.c, eval.c,
5542 findvar.c, infcmd.c, infptrace.c, infrun.c, m2-exp.y, parse.c,

5544 utils.c, valarith.c, valops.c, valprint.c, values.c:
5545 Replace bcopy() use with memcpy(), which is more standard and can
5546 take advantage of gcc's builtin functions for increased performance.
5547 * breakpoint.c, buildsym.c, coffread.c, dbxread.c, i386-tdep.c,
5548 ieee-float.c, infcmd.c, sparc-tdep.c, stack.c, symtab.c, symtab.h,
5549 target.c, values.c:
5550 Replace bzero() use with memset(), which is more standard and can
5551 take advantage of gcc's builtin functions for increased performance.
5552 * i386-tdep.c, main.c, valprint.c:
5553 Replace bcmp() use with memcmp(), which is more standard and can
5554 take advantage of gcc's builtin functions for increased performance.
5555
5556 Sun Jun 28 13:30:22 1992 Fred Fish (fnf@cygnus.com)
5557
5558 * remote.c (remote_wait): Fix cast on signal() call.
5559 * defs.h (alloca): More diddling with alloca. Have to ensure
5560 that it has a prototype, so that if alloca is defined as a macro
5561 that takes an arg, the definition is seen as a use of a macro
5562 that takes an arg, to satisfy picky ANSI preprocessors.
5563
5564 Sat Jun 27 12:12:20 1992 Fred Fish (fnf@cygnus.com)
5565
5566 * sparc-pinsn.c: Use <string.h> rather than "string.h", for

5757 C++ syms as demangled, not just functions.

5857
5858 * dbxread.c (end_psymtab): Only reset texthigh if it's not already
5859 set. Don't reset our own texthigh, or dependency-only pst's, in

6184 * valprint.c (type_print_1): Demangle using ansi option.
6185 * config/ncr3000.mt (DEMANGLE_OPTS): Remove -Dnounderscore.
6186
6187 Sat May 9 14:47:28 1992 Stu Grossman (grossman at cygnus.com)

6255 to cplus_demangle() or fputs_demangled() to use individual
6256 demangling options.
6257 * valprint.c (type_print_1): Change options to cplus_demangle
6258 to print demangled function args. Still broken, but now less so.
6259 * cplus-dem.c: Include demangle.h, reorganize and update some

6297 the make_*_type functions with a null storage alloc parameter.
6298 * gdbtypes.h (make_{reference,pointer,function}_type): Declare.

6308 (read_enum_type): Force enum values to file scope, due to bug in
6309 Sun compiler output. FIXME, fix later.
6310
6311 Remove unused header_file_prev_index mechanism. It was already
6312 obsolete in gdb-3.5. These comments appeared in 3.5:

6329 (Q2_3Foo3Bar as well as Q23Foo3Bar).
6330 Make cplus_demangle re-entrant by removing use of global
6331 variables. Instead, place all shared variables in a
6332 stack-allocated structure, and pass around its address.

6752 * procfs.c (attach, detach): Preserve and restore process flags
6753 using saved_* fields in procinfo struct.
6754 * procfs.c (attach): Call proc_signal_handling_change.
6755 * procfs.c (info_proc): Major rework to expand "info proc" cmd.

6769 * solib.c (solib_map_sections): Initialize pointer to ".text"
6770 section in so_list struct.
6771 * solib.c (symbol_add_stub): Pass base address of ".text"
6772 section to symbol_file_add, rather than the load address of
6773 the shared library. On SunOS they are the same. On SVR4 they
6774 are not.
6775
6776 Tue Mar 31 17:48:15 1992 Stu Grossman (grossman at cygnus.com)
6777
6778 * mipsread.c (parse_procedure): PDR.isym should get pointer to

6784
6785 Tue Mar 31 11:01:06 1992 Stu Grossman (grossman at cygnus.com)
6786
6787 * Makefile.in (VERSION): 4.4.8
6788
6789 * procfs.c (open_proc_file): Disable inherit-on-fork flag so that
6790 commands in .cshrc/.profile won't get traced.
6791
6792 Tue Mar 31 08:11:58 1992 John Gilmore (gnu at cygnus.com)

6799 Mon Mar 30 16:50:43 1992 Stu Grossman (grossman at cygnus.com)
6800
6801 * Makefile.in (alldeps.mak): Config files are now *.m[ht] as
6802 opposed to m[ht]-*!
6803
6804 * config/irix4.mh: Don't use coredep.o. It doesn't work with procfs.
6805
6806 * mipsread.c (parse_symbol, parse_procedure): Re-do the way that
6807 .gdbinfo. symbols are created. Move creation from parse_procedure
6808 to parse_symbol, where it is fairly easy to grow the symtab. This
6809 also fixes a symtab trashing bug on all mips-based systems.
6810 * (got_numargs, lookup_numargs, free_numargs): Delete. Not
6811 needed anymore.
6812 * tm-mips.h, tm-iris3.h, mips-tdep.c, mipsread.c: Re-do struct
6813 mips_extra_func_info, and all the PROC_xxx macros that look at it.

6893 * buildsym.c (read_range_type): Avoid int overflow by using unsigned.
6894 * dbxread.c (dbx_symfile_init): Remove bogus `lvalue cast'.
6895 * language.h (enum exp_opcode): Avoid forward enum def.
6896 * main.c (define_command, user_defined_command): Lint.

6908
6909 * objfiles.h (OBJF_SYMS): Define flag bit for objfile flags.
6910 * symfile.c (symbol_file_add): Use OBJF_SYMS to decide whether
6911 or not to try reading symbols from a mapped objfile. Plugs memory
6912 leak due to shared libraries generating no psymtabs or symtabs.
6913
6914 Fri Mar 27 15:44:55 1992 John Gilmore (gnu at cygnus.com)
6915
6916 * buildsym.c (MAX_OF_C_TYPE, MIN_OF_C_TYPE): Unused, remove.

6939 read_dbx_symtab): Remove the stringtab and stringtab_size params
6940 from the function prototypes, the function definition, and the
6941 function calls. These are now available via DBX_STRINGTAB and
6942 DBX_STRINGTAB_SIZE using the objfile pointer.
6943 * dbxread.c (dbx_symfile_read): Relocate addr before using as
6944 an arg to read_dbx_symtab.
6945 * dbxread.c (dbx_symfile_read): Remove code that free'd the
6946 stringtab and the dbx specific per-objfile private info.
6947 * dbxread.c (init_psymbol_list): Remove symbol count from passed
6948 args in prototype, function definition, and function calls. It is
6949 now available via the DBX_SYMCOUNT macro using the objfile
6950 pointer.
6951 * dbxread.c (dbx_symfile_read, dbx_symfile_init): Remove the
6952 local instance of struct dbx_symfile_info and replace with DBX_*
6953 macros.
6954 * dbxread.c (dbx_symfile_read): Remove init's of now deleted
6955 symfile_string_table and symfile_string_table_size.
6956 * dbxread.c (dbx_symfile_finish): Remove now obsolete free of
6957 symfile_string_table.
6958 * dbxread.c (init_psymbol_list): Use DBX_SYMCOUNT.
6959 * dbxread.c (dbx_psymtab_to_symtab): Remove local stringtab and

6961 the stringtab.
6962 * objfiles.c (allocate_objfile): Move calls to init_malloc()
6963 to prior to any calls to mmalloc for the objfile specific heap.
6964 * utils.c (init_malloc): Document the requirement that for each
6965 heap for which corruption checking is desired, that init_mmalloc
6966 must be called prior to any mmalloc calls on the heap.
6967
6968 Thu Mar 26 13:20:06 1992 Per Bothner (bothner@cygnus.com)
6969
6970 * rs6000-pinsn.c: Make dis-assembly output more like
6971 other targets: Don't print instruction in hex before
6972 the assembly; use print_address to print out jump
6973 destinations.
6974
6975 Wed Mar 25 16:52:35 1992 Per Bothner (bothner@cygnus.com)
6976
6977 * c-exp.y, gdbtypes.h: Add builtin_type_signed_char.

6979
6980 Wed Mar 25 15:21:44 1992 Stu Grossman (grossman at cygnus.com)
6981
6982 * configure.in: fix iris/iris3.
6983
6984 Wed Mar 25 14:55:48 1992 Per Bothner (bothner@cygnus.com)
6985
6986 * command.c, main.c (various places): Use ctype.h macros
6987 (such as isupper(x)), instead of hard-wiring in ASCII-isms
6988 (such as (x >= 'A' && x <= 'Z')).
6989 (There are still more of these in other files.)
6990 * main.c (defined_command): Lower-case the user's
6991 new command before entering it. Needed because
6992 command lookup is case-insensitive (and also lower-cases).
6993 (Based on Metin's earlier patch.)
6994
6995 Tue Mar 24 23:27:01 1992 K. Richard Pixley (rich@cygnus.com)
6996
6997 * config/irix4.mh: new file.

7006 * mipsread.c (fixup_sigtramp): Make sure that current_objfile is setup
7007 when calling new_symbol.
7008 * mips-tdep.c (mips_frame_chain): Use symfile_objfile instead of
7009 current_objfile.
7010
7011 Tue Mar 24 13:26:25 1992 Per Bothner (bothner@rtl.cygnus.com)

7016 as well as after, to work for AIX.
7017 * gdbtypes.h: Minor clarifiction.
7018
7019 Tue Mar 24 07:26:19 1992 Michael Tiemann (tiemann@cygnus.com)

7027 compilation errors.
7028
7029 Mon Mar 23 15:49:14 1992 Per Bothner (bothner@cygnus.com)
7030
7031 * valops.c (value_struct_elt_for_reference): Added 'offset'
7032 parameter to handle multiple inheritance.
7033 * eval.c, value.h: Update accordingly.
7034
7035 Fri Mar 20 17:43:27 1992 Fred Fish (fnf@cygnus.com)

7057 symfile.c, mips-tdep.c (startup_file_start, startup_file_end):
7058 Remove extern decls.

7098
7099 Thu Mar 19 18:49:45 1992 Per Bothner (bothner@cygnus.com)
7100
7101 More C++ improvements (pointers to members, qualified names).
7102 * c-exp.y: Support exp.type::name and exp->type::name
7103 syntaxes. (Unfortunately, doesn't work for static members.)
7104 * c-exp.y, eval.c: Make type::~type work better.
7105 * eval.c (evaluate_subexp: OP_SCOPE): Replace use of
7106 value_static_field by value_struct_elt_for_reference.
7107 * eval.c (evaluate_subexp): Merge code for STRUCTOP_MEMBER
7108 and STRUCTOP_MPTR; cast arg1 to domain-type of arg2.
7109 * eval.c (evaluate_subexp): Remove special case for UNOP_ADDR
7110 for OP_SCOPE operand; no point in it now that we use lazy
7111 reading of values, and use "reference to member" objects.
7112 * gdbtypes.h: Clarify comment.
7113 * valops.c: Change value_struct_elt_for_address to return
7114 a reference (or variable), rather than a pointer. Change
7115 the name to value_struct_elt_for_reference to reflect this.
7116 Returning a reference instead of a address provides a
7117 generalization, since we can use the routine for both
7118 class::name as well as &class::name.
7119 Also, recurse to handle multiple inheritance properly.
7120 * valprint.c: Moved code to print pointer-to-members
7121 to new function point_class_member. This allows a
7122 "reference-to-member" to be printed using the same code.
7123 * valprint.c (type_print_varspec_prefix): Avoid printing
7124 "struct " for domains of class-member types.
7125 * valops.c (search_struct_field): Inline code for simplified
7126 version of value_static_field (which can then be deleted).

7323
7324 Thu Mar 12 11:56:46 1992 Per Bothner (bothner@cygnus.com)
7325

7327 Ozisik) (dated Fri, 6 Mar 92 17:51) for the rs6000.
7328 * minsyms.c, symfile.c: Changes that may be generally
7329 applicable, but are #ifdef IBM6000 for now.
7330 * rs6000-xdep.c: Fixed typo in comment.
7331 * rs6000-tdep.c: Non-substatial changes.

7352 Fri Mar 6 21:59:34 1992 K. Richard Pixley (rich@cygnus.com)
7353
7354 * Makefile.in: added check target.
7355
7356 Thu Mar 5 23:56:01 1992 John Gilmore (gnu at cygnus.com)

7360 * remote.c (): Add newline to initial +.
7361 (remote_resume): Mention how to cope with signals.
7362 (remote_interrupt): Add debug msg.

7384
7385 Wed Mar 4 11:56:42 1992 Fred Fish (fnf@cygnus.com)
7386
7387 * defs.h, utils.c: xrealloc takes PTR as first arg.

7389 * defs.h: Some minor whitespace changes.
7390 * infrun.c (wait_for_inferior): Compare int tmp to int 0,

7400
7401 Tue Mar 3 15:11:52 1992 Michael Tiemann (tiemann@cygnus.com)
7402

7405
7406 Mon Mar 2 23:00:12 1992 Steve Chamberlain (sac@thepub.cygnus.com)
7407
7408 * gdbtypes.c (lookup_pointer_type): initialize the TYPE_LENGTH of
7409 a ptype to reflect the setting of TARGET_PTR_BIT. Set the
7410 TYPE_FLAGS of a ptype to TYPE_FLAG_UNSIGNED.
7411 * tm-h8300.h, h8300-tdep.c, remote-hms.c: personal checkpoint
7412 * printcmd.c (print_address): if ADDR_BITS_REMOVE is defined, use
7413 it before printing out the hex shape of an address.
7414
7415 Sun Mar 1 17:41:09 1992 Per Bothner (bothner@cygnus.com)
7416
7417 * rs6000-xdep.c (frame_initial_stack_address): Move
7418 code to set frame->cache_fsr into new separate function
7419 frame_get_cacahe_fsr. This allows fixing a fatal error.
7420 * xcoffexec.c: Turn previously suppressed error
7421 message back on, after cleaning up BFD.
7422
7423 * breakpoint.c (breakpoint_re_set): Removed (at least for now)
7424 printing of blank line, since it cases printing of an
7425 extra blank line. Is this intended? It does mess up
7426 gdb test suite.
7427 * defs.h: Put back declarations of malloc and realloc,
7428 but protected by #ifndef MALLOC_INCOMPATIBLE.
7429 * objfiles.c: Undo previous change: Use malloc/realloc

7433 Sat Feb 29 14:43:02 1992 Per Bothner (bothner@cygnus.com)
7434
7435 Changes from metin@ibmpa.awdpa.ibm.com (Metin G. Ozisik)
7436 [Mail dated Fri, 21 Feb 92 13:14:54 -0800]
7437 * buildsym.c: Use smash_to_pointer_type() to handle forward type
7438 references.
7439 * xcoffread.c: Modifications to C_DECL storage class handling, and
7440 introduction of an old smash_to_pointer_type() routine.
7441
7442 Changes from metin@ibmpa.awdpa.ibm.com (Metin G. Ozisik)
7443 [Mail dated Thu, 20 Feb 92 13:57:16 -0800]
7444 * rs6000-xdep.c, rs6000-tdep.c, tm-rs6000.h: function_frame_info()
7445 parameters have been modified.
7446
7447 Changes from metin@ibmpa.awdpa.ibm.com (Metin G. Ozisik)
7448 [Mail dated Thu, 20 Feb 92 10:10:05 -0800]
7449 * rs6000-tdep.c: Before Feb 5 92, register_valid[] array was not used,
7450 and fetch_inferior_registers() always fetched all the registers
7451 resulting valid register values at hand all the time. Pushing a dummy
7452 frame did not require validating all register values first. After
7453 putting the above mechanism into action, we didn't have valid registers
7454 values always ready. Thus, all registers need to be fetched before
7455 pushing a dummy frame now.
7456
7457 Changes from metin@ibmpa.awdpa.ibm.com (Metin G. Ozisik)
7458 [Mail dated Thu, 13 Feb 92 16:22:44 -0800]
7459 * rs6000-xdep.c: frame_initial_stack_address() function to calculate
7460 the starting address (actual frame address) of a frame.
7461 * rs6000-tdep.c: modifications to function_frame_info() to see if
7462 function reserves a frame pointer register (alloca register)
7463 * tm-rs6000.h: EXTRA_FRAME_INFO, FRAME_ARGS_ADDRESS and
7464 FRAME_LOCALS_ADDRESS has been updated to support debugging of
7465 functions with alloca() calls.
7466
7467 Sun Mar 1 13:13:39 1992 Fred Fish (fnf@cygnus.com)
7468
7469 * xm-sysv4.h: Provide definitions/prototypes for host environment
7470 functions for which no definitions or prototypes are provided in
7471 any currently included gdb or host environment header files.
7472 For SVR4, this currently includes malloc and realloc, which cannot
7473 be portably prototyped in any gdb include file.
7474
7475 Sat Feb 29 14:43:02 1992 Per Bothner (bothner@cygnus.com)
7476
7477 * buildsym.h: Remove obsolete variable file_stabs.
7478
7479 * Makefile.in: Move place where configure merges in host-
7480 and target-dependent fragments later, so the latter
7481 can override (say) GNU_MALLOC.
7482 * config/mh-rs6000: Use system malloc. Otherwise, I
7483 ended up with *two* incompatible versions of malloc
7484 (functions in libc would call the malloc in libc).
7485 I assume this is a shared library problem.
7486
7487 * remote.c: Fix (presumed) typo.
7488 * objfiles.c: Use xmalloc/xrealloc instead of
7489 malloc/realloc (since the latter are no longer declared).
7490
7491 Changes from metin@ibmpa.awdpa.ibm.com (Metin G. Ozisik)
7492 [Mail dated Thu, 6 Feb 1992 10:22:02 -0800]
7493 * rs6000-xdep.c: Improvements to fetch_inferior_registers() to
7494 handle individual registers.
7495 * tm-rs6000.h: Fix SAVED_PC_AFTER_CALL macro to handle pc value
7496 correctly in case it wasn't cached yet. (A problem showed up
7497 after fetching individual registers.)
7498 * buildsym.c: Disable type_synonym_name's type name overwriting
7499 in cases it is unnecesary. rs6000 portation doesn't use
7500 type_synonym_name, and it used to nullify type names
7501 * xcoffread.c: to handle g++'s typename abbreviation, fill in a
7502 type's name as soon as space for that type is allocated.
7503 * xcoffread.c: ignore a section's lineno information if it is
7504 not `.text'. (In rs6000 bfd portation integration, skipping over
7505 `.pad' sections are ignored since it was in machine independent
7506 part of the code. Thus, a problem of fake sections with invalid
7507 lineno information arised.)

7509 Changes from metin@ibmpa.awdpa.ibm.com (Metin G. Ozisik)
7510 [Mail dated Thu, 6 Feb 1992 13:26:22 -0800]
7511 * rs6000-tdep.c: make function_frame_info() work whether or not
7512 reading from a core file.
7513 * tm-rs6000.h: Implementation of FRAME_FIND_SAVED_REGS macro.
7514
7515 * infrun.c. main.c, printcmd.c. symtab.c:
7516 More changes from IBM for rs6000.
7517
7518
7519 Thu Feb 27 22:57:19 1992 Per Bothner (bothner@cygnus.com)
7520
7521 * rs6k-opcode.h, tm-rs6000.h, xm-rs6000.h, rs6000-tdep.c,
7522 rs6000-xdep.c, xcoffexec.c, xcoffread.c:
7523 Merge in changes (mostly from IBM) for RS6000.
7524 * breakpoint.c, buildsym.c, infptrace.c, stack.c, symtab.c:
7525 More changes from IBM for RS6000. These are in machine-
7526 independent code, and probably could do with some cleaning
7527 up. The most questionable of these are #ifdef IBM6000.
7528 * infrun.c, sparc-tdep.c: Pass a parameter (signal number)
7529 to single_step() (for consistency with rs6000 and i860).
7530 * utils.c: Allow the 1st arg to xrealloc to be NULL
7531 (in which case do malloc). This removes the need for
7532 some tests in xcoff code (and perhaps other places?).
7533 * coffread.c: Removed variables last_source_file,
7534 type_vector, and type_vector_length as these are now
7535 defined by buildsym.[ch].
7536 * defs.h: Remove prototypes for malloc and realloc, since
7537 these should only be used to implement xmalloc and xrealloc,
7538 and they conflict with <stdlib.h> in AIX - where they
7539 return void* even when __STDC__ isn't defined. Sigh.
7540 * munch: Recognize *initialize* in data as well as text
7541 (AIX uses data). Also, incorporate a patch from Garrett
7542 Wollman <wollman@uvm-gen.uvm.edu> to make the sed script
7543 much more sensible, by only trying to match the name of
7544 the initialize_foo function, and not the junk before it.
7545
7546 Thu Feb 27 20:07:43 1992 Stu Grossman (grossman at cygnus.com)
7547
7548 * breakpoint.c (breakpoint_re_set_one): Don't reset breakpoint

7551 Thu Feb 27 11:48:47 1992 John Gilmore (gnu at cygnus.com)
7552
7553 * remote.c: Make it work for embedded MIPS. Increase buffer
7554 size, and use throughout. Round buffer size up if too many regs.
7555 Support baud rate setting and try for an 8-bit path. If
7556 interrupted while waiting for target, send a ^C down the wire.
7557 Avoid single-byte reads.
7558 * tm-mips.h: Add more embedded-system registers to REGISTER_NAMES
7559 and NUM_REGS.

7564 of the four possible byte orders.

7578 symfile.c (syms_from_objfile): Re-do
7579 insertion of longjmp breakpoints. Move all code into
7580 breakpoint_re_set, and call that instead of

8013 target.c, target.h, valarith.c, valops.c, value.h, xcoffexec.c:
8014 Remove to_call_function and target_call_function, since it
8015 always calls the same thing (call_function_by_hand).
8016 * core.c, exec.c, solib.c: Rename target_ops sections =>
8017 to_sections, etc.
8018 * infcmd.c, inflow.c, infptrace.c, infrun.c, main.c, target.c,
8019 target.h: target_kill takes no args.
8020 * language.c (language_info): Scaffolding to allow briefer
8021 messages when the current language changes. FIXME.

8026 Thu Feb 20 09:04:18 1992 Fred Fish (fnf at cygnus.com)
8027
8028 * defs.h: Include ansidecl.h and PARAMS macro. Use PARAMS
8029 to make prototypes for all functions declared here.
8030 * cplus-dem.c: Avoid declaring xmalloc and xrealloc.
8031 * c-exp.y: Rename SIGNED, OR, and AND to avoid conflict.

8035 * m2-exp.y: Remove unused CONST; Rename OR and AND.
8036 * utils.c: Avoid declaring malloc and realloc. Lint.

8038
8039 Mon Feb 17 07:13:27 1992 Fred Fish (fnf at cygnus.com)
8040
8041 * dwarfread.c (process_dies): Add case to handle TAG_pointer_type
8042 DIE's. Add new function read_tag_pointer_type() to read them.
8043
8044 * dwarfread.c (dwarf_read_array_type, read_subroutine_type):
8045 When creating a new user defined type, check to see if a partial
8046 type already exists, and if so, bash it to fit.
8047
8048 Fri Feb 14 19:00:17 1992 John Gilmore (gnu at cygnus.com)
8049
8050 * coffread.c (decode_base_type): Pass long, not union.

8065
8066 Fri Feb 7 11:51:12 1992 Per Bothner (bothner at cygnus.com)
8067
8068 * mips-tdep.c (mips_print_registers): Print correct register
8069 number for double pseudo-registers.
8070
8071 Fri Feb 7 07:56:05 1992 John Gilmore (gnu at cygnus.com)
8072
8073 * buildsym.c (read_struct_type): Avoid double-bump of parse ptr
8074 in the op$::OPERATOR. case. From Steven McCanne,
8075 <mccanne@horse.ee.lbl.gov>.
8076
8077 * exec.c (set_section_name): Pass arg to exec_files_info;
8078 only call it if interactive. From Francis Kauth <fk@tv.tv.tek.com>.
8079
8080 Thu Feb 6 17:41:32 1992 John Gilmore (gnu at cygnus.com)
8081
8082 * main.c (print_gdb_version): Copyright msg: only this year.

8084
8085 Thu Feb 6 15:14:01 1992 Per Bothner (bothner at cygnus.com)
8086
8087 * mipsread.c (parse_partial_symbols): Handle dependencies
8088 between partial symbol tables (when not doing stabs-in-ecoff).
8089 (This used to be handled by parse_fdr, but parse_fdr was
8090 incompatible with handling stabs-in-ecoff, so the code
8091 was re-written to not use parse_fdr. Unfortunately,
8092 the logic to handle dependencies was overlooked.)
8093
8094 Thu Feb 6 11:51:39 1992 Steve Chamberlain (sac at rtl.cygnus.com)
8095
8096 * coffread.c (read_enum_type): Use the size of a target int when
8097 describing enum.
8098 * defs.h: added new #define for TARGET_PTR_BIT, defaults to size
8099 of target int.
8100 * h8300-tdep.c, remote-hms.c, tm-h8300.h: too many changes to count
8101 * symtab.c (lookup_reference_type, lookup_ptr_type): use
8102 TARGET_PTR_BIT to determine size of a pointer
8103 * values.c (unpack_long): when unpacking a REF or a PTR don't
8104 assume the size of the type.
8105
8106 Wed Feb 5 22:29:59 1992 John Gilmore (gnu at cygnus.com)
8107
8108 * mipsread.c (parse_symbol): Avoid clobbering enum pointer when
8109 looking at its members. Improve guess between struct and union,
8110 only assuming union if multiple members have offsets of zero.
8111
8112 Tue Feb 4 18:05:44 1992 Per Bothner (bothner at cygnus.com)
8113
8114 * mipsread.c: Use (FP0_REGNUM-32) instead of magic number 6.
8115 (This is just for clarity - and one day permitting us to
8116 change FP0_REGNUM from 38 to 32, which would make more sense.)
8117 * tm-mips.h: Added STAB_REG_TO_REGNUM macro, so that
8118 register numbers in stabs-in-ecoff get handled correctly.
8119
8120 Sat Feb 1 04:45:10 1992 Stu Grossman (grossman at cygnus.com)
8121
8122 * xm-vax.h, xm-vaxult.h, xm-vaxbsd.h, config/mh-vaxult,
8123 config/mh-vaxbsd, configure.in: Split up config stuff for Vaxen
8124 into BSD and Ultrix.
8125
8126 Sat Feb 1 04:39:41 1992 John Gilmore (gnu at cygnus.com)
8127
8128 * dbxread.c (dbx_symfile_init): Call malloc, not xmalloc.
8129
8130 Sat Feb 1 04:15:41 1992 Stu Grossman (grossman at cygnus.com)
8131
8132 * Makefile.in: Increment version to 4.4.1.
8133 * main.c (print_gdb_version): Update copyright notice.
8134
8135 Sat Feb 1 01:43:11 1992 Per Bothner (bothner at cygnus.com)
8136
8137 * mipsread.c: Prepend "struct " to the names of structure
8138 types, and similarly for enums and unions. (This used
8139 to be done, but got lost in the re-write to "guess" the
8140 difference between enum/struct/union.)
8141 Also, guess that a tag is an enum if the first member
8142 has type btNil.
8143
8144 Fri Jan 31 21:45:51 1992 Stu Grossman (grossman at cygnus.com)
8145
8146 * xm-vax.h: #ifndef ultrix around #include of endian.h and
8147 limits.h (sigh).
8148
8149 Fri Jan 31 00:05:01 1992 John Gilmore (gnu at cygnus.com)
8150
8151 * Projects: Patching executables is done.
8152 * Makefile.in (VERSION): Roll to gdb-4.4.
8153 * README, WHATS.NEW: Update for gdb-4.4.
8154
8155 * symfile.c (reread_symbols): Whenever we reread one object
8156 file's symbols, we must restart the scan, because the object_files
8157 chain has been permuted.
8158
8159 * exec.c (exec_files_info): Split out into print_section_info.
8160 Print BFD filename of each section if it's not the default one.
8161 * core.c (core_files_info): Call print_section_info.
8162
8163 * xm-vax.h: Include a few system header files whose definitions
8164 must precede defs.h.
8165 * language.c, language.h: Make some things const.
8166 * expression.h, main.c: const spreads like ooze.
8167
8168 * mem-break.c (break_insn, break_insn_size): Use unsigned chars,
8169 since BREAKPOINT values can be >0x80.
8170
8171 Thu Jan 30 17:21:14 1992 Stu Grossman (grossman at cygnus.com)
8172
8173 * infrun.c, xm-i386sco.h: SCO needs to use setpgid().
8174
8175 Thu Jan 30 01:04:23 1992 John Gilmore (gnu at cygnus.com)
8176
8177 * sparc-pinsn.c: Remove kludge for preferring architectures.
8178 Remove #ifdef's for SORT_NEEDED. We need to sort the table, now
8179 and forever. Add `add' instruction to the set that get checked
8180 for a preceding `sethi' in order to print an absolute address.
8181 Corresponding changes in ../include/opcode/sparc.h needed
8182 to eliminate garbage instructions.
8183
8184 Wed Jan 29 19:24:34 1992 Per Bothner (bothner at cygnus.com)
8185
8186 * mipsread.c (parse_partial_symbols): Make sure partial
8187 symbols are created for external symbols (as used to be
8188 the case). This is a bit of a pain with the mips-coff.
8189 It uses a table which points to all of the external
8190 symbols belonging to a particular FDR or psymtab.
8191 Once we've generated this table, we might as well save
8192 it, and then use it in psymtab_to_symtab_1 to find
8193 the symbols to pass to parse_external().
8194 * symfile.c, symfile.c: New function start_psymtab_common
8195 to share the common parts of allocating a new psymtab
8196 for dbxread, mipsread (and later dwarfread). Its code
8197 was pulled out from start_psymtab in dbxread.c.
8198 * dbxread.c (start_psymtab): Use start_psymtab_common().
8199
8200 * valprint.c (val_print): If there is an error when trying
8201 to print a string, check to see if there really is a problem
8202 by reading just one character. If that works, assume
8203 things are ok.
8204
8205 Wed Jan 29 18:58:43 1992 Stu Grossman (grossman at cygnus.com)
8206
8207 * sparc-pinsn.c (compare_opcodes): Make it prefer v6, v7,
8208 cypress, v8 mnemonics in that order.
8209
8210 Tue Jan 28 17:32:13 1992 Per Bothner (bothner at cygnus.com)
8211
8212 * sparc-pinsn.c: Put the qsort() back in.
8213
8214 Mon Jan 27 18:51:03 1992 John Gilmore (gnu at cygnus.com)
8215
8216 * findvar.c (read_register, write_register): Handle machines
8217 where REGISTER_TYPE is not the same size as "int".
8218
8219 Handle debug symbols in dynamically loaded (relocated) code:
8220
8221 * dbxread.c (read_ofile_symtab): Fix up N_CATCH better. Pass
8222 offset to process_one_symbol.
8223 (process_one_symbol): Take new offset parameter. Add it into
8224 appropriate symbol types to relocate symbols to loaded addresses.
8225 Handle all possible symbol types, and complain() about types that
8226 we don't expect to see.
8227 * mipsread.c (psymtab_to_symtab_1): Pass offset of zero to
8228 process_one_symbol (FIXME, should pass real offset).
8229
8230 Misc bugfixes:
8231
8232 * breakpoint.c (resolve_sal_pc): Split out code to resolve a
8233 sal's PC value.
8234 (set_breakpoint, break_command_1, until_break_command,
8235 catch_command_1, breakpoint_re_set_one): Use it.
8236 * symtab.h (resolve_sal_pc): Declare.
8237 * infcmd.c (jump_command): Use resolve_sal_pc.
8238
8239 * source.c (list_command): Shorten "FILE, line N" to "FILE:N".
8240
8241 * putenv.c (putenv): Avoid unportably casting pointers to unsigneds.
8242
8243 * c-exp.y (yylex): `this' and `template' are only tokens in C++.
8244
8245 * xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
8246 xm-np1.h, xm-pn.h, xm-pyr.h, xm-rtbsd.h, xm-symmetry.h, xm-umax.h:
8247 Remove MISSING_VPRINTF declaration, and superfluous "kgdb" defines.
8248
8249 Mon Jan 27 15:46:21 1992 Stu Grossman (grossman at cygnus.com)
8250
8251 * dbxread.c (process_one_symbol): Make a first cut at handling
8252 symbol tables generated by Sun's acc. (#ifdef'd out, FIXME.)
8253
8254 * symtab.c (find_pc_line): Fix stepping into and out of #included
8255 files.
8256
8257 Mon Jan 27 13:00:55 1992 Stu Grossman (grossman at cygnus.com)
8258
8259 * Makefile.in (OPCODES): Remove OPCODES defs and refs. There is
8260 no longer any need to copy ../include/opcode/* into gdb.
8261
8262 Mon Jan 27 12:30:38 1992 John Gilmore (gnu at cygnus.com)

8267
8268 * valprint.c (type_print_base, type_print_method_args):
8269 Print C++ constructor methods without bogus "return type."
8270
8271 Sat Jan 25 15:57:59 1992 Fred Fish (fnf at cygnus.com)
8272
8273 * infptrace.c (child_xfer_memory): Parameter "target" should
8274 be a pointer to a structure, not the entire structure.
8275
8276 Fri Jan 24 01:30:27 1992 Fred Fish (fnf at cygnus.com)
8277
8278 * depend: Convert the couple of references to ansidecl.h that
8279 used the local gdb version to use the ../include version.
8280
8281 Thu Jan 23 22:24:43 1992 Fred Fish (fnf at cygnus.com)
8282
8283 * procfs.c
8284 (child_xfer_memory): Takes pointer to a struct, not entire struct.
8285 (inferior_proc_init): Fix non-ANSI version of args.
8286 (attach): Call print_sys_errmsg with correct number of args.
8287 (mappingflags): Make static, does not need to be global.
8288
8289 * i386-tdep.c (i386_frame_num_args): Takes a pointer to a struct
8290 not the entire struct itself.
8291
8292 * valops.c (value_assign): Cast some args to modify_field() and
8293 {read,write}_register_bytes() correctly.
8294
8295 * ansidecl.h: Removed, is duplicate of ../include/ansidecl.h
8296
8297 * Makefile.in (MALLOCSRC): Removed reference to removed local
8298 copy of ansidecl.h.
8299
8300 * dwarfread.c (list_in_scope): Needs an initial value, use file
8301 scope.
8302
8303 Mon Jan 20 19:06:28 1992 Stu Grossman (grossman at cygnus.com)
8304
8305 * main.c (main): Make option_index local to keep new getopt happy.

8309
8310 * cplus-dem.c (cplus_demangle): Correctly demangle destructors.

8313
8314 * Makefile.in (HFILES): Add partial-stab.h.
8315
8316 Sat Jan 18 16:45:01 1992 Fred Fish (fnf at cygnus.com)
8317
8318 * config/mh-stratus, config/mt-stratus, tm-stratus.h, xm-stratus.h:
8319 New files for stratus. Not complete enough to actually build
8320 on the Stratus machine; that awaits copyright assignment for
8321 i860 changes.
8322
8323 * Makefile.in (USER_CFLAGS): Add macro specifically reserved
8324 for getting custom flags into CFLAGS when doing makes.
8325

8327
8328 Thu Jan 16 00:51:46 1992 Fred Fish (fnf at cygnus.com)
8329
8330 * dbxread.c (process_one_symbol): Pass address of structure
8331 to complain(), rather than the whole structure.
8332
8333 Wed Jan 15 09:56:16 1992 Fred Fish (fnf at cygnus.com)
8334
8335 * solib.c (solib_add_common_symbols): Only compile in when not
8336 using SVR4 style shared libraries.
8337
8338 Tue Jan 14 22:34:00 1992 Fred Fish (fnf at cygnus.com)
8339
8340 * dwarfread.c (locval): Add offreg flag to indicate location
8341 values that are computed off a base register.
8342
8343 * dwarfread.c (new_symbol): Rework TAG_global_variable and
8344 TAG_local_variable cases to account for static variables
8345 within function scopes.
8346
8347 Tue Jan 14 12:28:52 1992 Stu Grossman (grossman at cygnus.com)
8348
8349 * inflow.c: remove #include <sys/dir.h>. Not necessary, and
8350 doesn't exist on some systems.
8351
8352 * infrun.c (wait_for_inferior!!!!): Prevent gdb from hanging when
8353 nexting over recursive function calls.
8354
8355 * target.c (target_read_string): Create this routine to read null
8356 terminated strings from the target. It deals with running off the
8357 end of memory elegantly as well. solib.c (find_solib): Use
8358 target_read_string() to avoid problems with running off the end of
8359 memory.
8360
8361 * inflow.c (child_terminal_info): #ifdef TIOCPGRP around lines
8362 that reference pgrp_inferior.
8363
8364 Mon Jan 13 14:57:11 1992 Per Bothner (bothner at cygnus.com)
8365
8366 * tm-mips.h: Removed BLOCK_ADDRESS_ABSOLUTE, now that
8367 mips-tfile has been hacked to act more "traditionally."
8368 * dbxread.c: Fixed typo in comment.
8369
8370 Sun Jan 12 13:08:36 1992 Per Bothner (bothner at cygnus.com)
8371
8372 * mips-tdep.c (mips_skip_prologue): Add some number of
8373 'sw' instructions before 'addiu' adjusts the stack.
8374
8375 Fri Jan 10 13:47:06 1992 Fred Fish (fnf at cygnus.com)
8376
8377 * dwarfread.c (start_symtab, end_symtab, scopecount, openscope,
8378 freescope, buildblock closescope, record_line, add_symbol_to_list,
8379 gatherblocks, make_blockvector): Extensive changes to switch
8380 to generic symbol table building code in buildsym.c. Remove
8381 scope tree structures and functions, symbol table building
8382 functions, and lots of other small changes.
8383
8384 * dwarfread.c: Add new macros GCC_PRODUCER and STREQN. Remove
8385 GCC_COMPILED_FLAG_SYMBOL and GCC2_COMPILED_FLAG_SYMBOL.
8386
8387 Tue Jan 7 13:09:57 1992 Stu Grossman (grossman at cygnus.com)
8388
8389 * buildsym.c (cleanup_undefined_types): Add support for enums.
8390 This fixes the 'GDB internal error. cleanup_undefined_types with
8391 bad type' problem.
8392
8393 Sun Jan 5 09:47:50 1992 Stu Grossman (grossman at cygnus.com)
8394
8395 * dbxread.c: detect gcc2 compilations.
8396
8397 Thu Jan 2 15:07:41 1992 John Gilmore (gnu at cygnus.com)
8398
8399 * sparc-pinsn.c: Rename bitfields that overlap with macro names
8400 in ../include/opcode/sparc.h.
8401
8402 Wed Jan 1 04:29:00 1992 Fred Fish (fnf at cygnus.com)
8403
8404 * Makefile.in: Change tm-svr4.h to tm-sysv4.h. Change xm-svr4.h
8405 to xm-sysv4.h. Split OPCODE_DIR into OPCODE_DIR1 and OPCODE_DIR2
8406 to reflect actual locations of opcode files, so TAGS target will
8407 be buildable.
8408
8409 * i386-tdep.c: Change an erroneous 'm68k' reference to 'i386'.
8410
8411 * i386-tdep.c (supply_fpregset, fill_fpregset): Remove m68k
8412 code.
8413
8414 * m68k-tdep.c (supply_fpregset, fill_fpregset): Fix array
8415 dereferencing to access the correct elements.
8416
8417 * valops.c (value_addr): Declare return type of external func
8418 value_copy().
8419
8420 * xcoffread.c: Undefine next_symbol_text before redefining it.
