576 Permit symbols to be superseded when new symbol files have
577 been read in, particularly for VxWorks.
579 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
580 to the main file, as well as to include files. Also, put global
581 functions into the global psymtab, to make "i fun" work.
582 (end_psymtab): Free named symtabs and psymtabs for a file, once a
583 new psymtab for it has been read.
584 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
585 a file, once a new symtab has been read for it.
586 * mipsread.c: FIXME. We need to do the same for MIPS, but it
587 looks harder to determine the top-level block before it's been
588 queued to the psymtab list.
590 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
591 If we have wiped out any old symbol tables, clean up at end of
593 (symbol_file_command): Don't reference symfile_fns if it's zero.
595 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
596 defines for the blocks of a blockvector that contain global and
597 file-static symbols and the first of the smaller scope contours.
598 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
599 decode_line_1, make_symbol_completion_list): Use the above.
600 * coffread.c (end_symtab, patch_opaque_types): Ditto.

606 * symtab.c (list_symbols): Process the first symbol of the
607 static psymbols list.
608 (types_info): Restore this function from its untimely #if 0.
609 It's not perfect, but it is better than nothing.
610 (_initialize_symtab): Restore "info types".
612 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
614 * m68k-stub.c: Remote stub for 680x0's, created from
615 rem-m68k.shar (which is removed).
616 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
617 Remove RCS log stuff now that we use CVS and it blows our diffs.
619 Thu Apr 18 18:08:30 1991 John Gilmore (gnu at cygint.cygnus.com)
621 * symfile.h (free_named_symtabs): Rename from free_named_symtab.

632 Sat Apr 13 14:46:07 1991 John Gilmore (gnu at cygint.cygnus.com)
634 Permit symbols to be superseded when new symbol files have
635 been read in, particularly for VxWorks.
637 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
638 to the main file, as well as to include files. Also, put global
639 functions into the global psymtab, to make "i fun" work.
640 (end_psymtab): Free named symtabs and psymtabs for a file, once a
641 new psymtab for it has been read.
642 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
643 a file, once a new symtab has been read for it.
644 * mipsread.c: FIXME. We need to do the same for MIPS, but it
645 looks harder to determine the top-level block before it's been
646 queued to the psymtab list.
648 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
649 If we have wiped out any old symbol tables, clean up at end of
651 (symbol_file_command): Don't reference symfile_fns if it's zero.
653 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
654 defines for the blocks of a blockvector that contain global and
655 file-static symbols and the first of the smaller scope contours.
656 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
657 decode_line_1, make_symbol_completion_list): Use the above.

670 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
672 * m68k-stub.c: Remote stub for 680x0's, created from
673 rem-m68k.shar (which is removed).
674 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
675 Remove RCS log stuff now that we use CVS and it blows our diffs.
677 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
679 * symmisc.c (free_named_symtab): Make it work, in its current
680 kludgy fashion. Change result to indicate if we blew away bkpts.
681 * dbxread.c (end_symtab): Accumulate result from
682 free_named_symtab and print warning if we blew user's state.
683 * symfile.h: free_named_symtab now returns an int.
685 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
687 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
688 is the first symbol read, even if not mainline.
689 (dbx_psymtab_to_symtab): symfile might be zero, cope.
690 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
691 (set_section_command): New command ("section xxx yyy" -- should
692 be renamed to "set section xxx yyy" FIXME) which sets the
693 base address of a section of the exec file, overriding the
694 virtual address that BFD reports.
696 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
698 * exec.c: Add add_syms_addr_command to exec_ops, so you can
699 load symbols at any address while examining an exec file.
701 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
703 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
704 for printing the float info is host-dependent, not
705 target-dependent. FIXME.
706 * i386-pinsn.c: Move #includes to top, remove useless ones.
707 * i386-tdep.c: Don't bother including <.../reg.h> since we
708 don't use it (and it doesn't exist on host systems).
710 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
711 Convert negative numbers properly.
712 (ieee_test): Make numbers really random; fix format arg.
714 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
715 * core.c (core_detach): Unpush core_ops, which might not be on
716 top. We used to just pop the top, which broke things. Don't
717 need dont_repeat() any more.
718 (core_file_command): Psst! Don't repeat it.
719 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
720 * expprint.c (print_subexp): Avoid switch fallthru on
721 BINOP_ASSIGN_MODIFY, so we can print += and such.
723 * inflow.c (kill_command): After killing inferior, print our
724 current frame in the core file, if we have one.
725 (generic_mourn_inferior): When inferior dies, either select
726 the current frame (in the new target, e.g. core file), or
727 set both the current and selected frames to NULL.
729 Changes from Peter Schauer.
731 * infptrace.c: Avoid <sys/ptrace.h> on USG.
733 * Make all file names fit in 14 characters (sigh and damn!):
734 mv hp300hpux-xdep.c hp300ux-xdep.c
735 mv symmetry-xdep.c symm-xdep.c
736 mv symmetry-tdep.c symm-tdep.c
737 mv convex-opcode.h convx-opcode.h
738 mv tm-vxworks960.h tm-vx960.h
739 mv tm-vxworks68.h tm-vx68.h
740 mv Makefile.srcdir Makefile.sdir
741 mv gdb-int.texinfo gdbint.texinfo
742 mv remote-sa.m68k.shar rem-m68k.shar
743 mv remote-multi.shar rem-multi.shar
744 * Makefile.dist, README, config.gdb, convex-pinsn.c,
745 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
746 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
749 * command.c (user_info_1, user_info): New command for listing
750 the user-defined commands.
752 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
754 * dbxread.c (really_free_pendings): Clear file_symbols
755 and global_symbols after freeing them; otherwise, running
756 this function twice (if it appears twice on the cleanup
757 chain), we try to free things twice.
759 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
760 based on text_addr (the address of text in core), not on addr (the
761 offset between text in the .o file and in core). This change
762 is from Peter Schauer.
764 * main.c: Define ALL_CLEANUPS as a cast of zero.
765 (return_to_top_level): Use it.
766 (main): Do all cleanups after each command run as part
767 of the gdb startup sequence. Also do all cleanups before
768 entering the command loop, and every time we exit the command
769 loop and reenter. Before, the cleanups from the startup sequence
770 were being left undone until the first error!
771 (command_loop): Rename do_nothing cleanup to command_loop_marker
772 so we can see it easily when examining the cleanup chain.
773 (init_signals): Add another do_nothing for signal handling.
774 (quit_command): Only try to kill target if it has execution.
775 Problems in the target stack got us into a state where
776 inferior_pid was nonzero but none of the targets had execution.
777 In this state you couldn't exit gdb.
779 * dbxread.c: Two changes from Peter Schauer.
780 (echo_command): Fflush output after an echo command.
781 (show_history): Pass all args to cmd_show_list.
783 * utils.c (init_malloc): Call mtrace to turn on tracing
784 if the environment variable MALLOC_TRACE is set to a file name.
785 * mtrace.c: Add source file which provides a log of every malloc,
786 free, and realloc to a trace file.
787 * mtrace.awk: Add source file which analyzes the trace file.
788 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
789 (VERSION): Roll to 3.94.3.
791 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
792 (check_duplicates): Don't bother with watchpoints.
793 (set_raw_breakpoint): Comment about danger of this routine.
794 (watch_command): Parse and eval all args before calling
797 * solib.c (find_solib): Avoid error in referencing memory to
798 see if any more shared libraries have been added. This is
799 particularly useful if the target has terminated. Bug reported
802 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
803 in bringing up 3.94.2 on the Sun-3.
805 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
806 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
807 expression (in scope) before reenabling watchpoint.
808 * signame.c (init_sigs): Add missing declaration of i, fix
809 sys_siglist declaration.
810 * source.c (list_command): Fixed range computation to use
812 * stack.c (backtrace_command): Do not allow command if target has
813 no stack, print informative error message.
814 * target.c (target_command): Do not write into command line
815 because this fails if the target command is used in a user defined
816 command. [This change was enhanced by gnu to support any-
817 unique-prefix matching on target names.]
818 * valops.c (value_struct_elt): Avoid infinite loop on an
819 erroneous attempt to print the member of function (try p main.p).
821 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
823 * expread.y (name_no_typename): Avoid reduce/reduce errors
824 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
825 Since the GDB parser really doesn't use name_no_typename in a
826 name-only context, the parser can't tell the diff between
827 names and numbers here. Avoid allowing a name_no_typename
828 to be a NAME_OR_*INT to resolve the conflict.
830 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
832 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
834 * valprint.c (val_print_fields): bitfield printing didn't handle
835 byte order. Indirect through a few more fns to cope.
837 * values.c (modify_field): also cope with byte order.
839 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
841 Cleanup for release 3.94.2:
843 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
844 include files. Roll version to 3.94.2.
846 * coffread.c (init_stringtab): Read length into unsigned char
847 array before swapping; don't assume 32-bit longs.
849 * target.c (target_info): Don't bother with get_sym_file, just use
850 the symfile global variable.
851 * symtab.h, symfile.c (get_sym_file): Delete it.
853 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
854 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
855 (read_type): Replace one more error() with complain().
857 * mipsread.c (parse_partial_symbols): Replace printf with complain.
859 * i960-tdep.c: Fix copyright attribution.
861 * config.gdb: Quote all backquotes in doublequotes. You can
862 quote me on that. BSD 4.4 shell found this one.
864 * infptrace.c (throughout): The third argument to ptrace is an
867 * infrun.c (wait_for_inferior): When program has terminated, we
868 have to call target_terminal_ours before we pop that target off
869 the stack (e.g. before a call to target_kill or
870 target_mourn_inferior). This fixes problem where a program
871 terminates, then GDB stops for (tty output) and you have to type
872 "fg" to the shell to resume it. FIXME: This code for what to
873 do after termination really should be in normal_stop instead.
875 * gdbcore.h (read_memory_check): Change declaration; it changed
878 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
879 4.4 prereleases, this avoids a bug in their sgtty compatability
881 * remote.c: Use terminal.h rather than hand-rolling the same.
883 * signame.c, signame.h (psignal): Arg is unsigned, not int.
884 * utils.c (strsave, strstr): Fix arg types.
885 * valprint.c (val_print): lint
887 MIPS symbol table support from Per Bothner:
889 * symfile.c (symtab_fns): Remove initializer table that needs to
890 be hacked for each new symbol file format supported.
891 (add_symtab_fns): New function, chains symbol table
892 handlers into the global list.
893 (symfile_init): Search this list.
894 * symfile.h: Add next pointer, declare add_symtab_fns.
895 * coffread.c (_initialize_coffread): Call add_symtab_fns.
896 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
898 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
899 symbol *). Thus, we no longer need the hack to trash
900 pst->filename. Good, since that hack confused code in symfile.c!
902 (reorder_symtabs, destroy_all_symtabs): Removed static
903 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
904 Instead, the latter now uses a temporary array (stack-allocated
905 from an obstack, and then freed).
907 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
908 haven't been set in the outermost stBlock of a procedure. This was
909 a problem with f77 binaries on Ultrix 4.?.
911 (new_symtab, new_symbol, new_type): Continue changing code to use
912 obstacks more and otherwise conform to dbxread internal style.
913 Made the free_code of symtabs be free_linetable (as in dbxread)
914 instead of free_contents. This implies memory leaks when reading
915 a new symbol table, until the conversion is finished. Did change
916 (struct symbol) and (struct type) to be allocated on the
917 symbol_obstack. Blocks and blockvectors are among the things
920 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
921 tested much, but it solved one problem (reported by Meissner), and
922 cleans up some other things. The problem happened when an
923 included file contains actual code (functions) and not just
924 definitions. The mips coff is a little inconvenient there, since
925 it may cause a procedure to be mapped to the wrong psymtab.
927 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
928 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
929 this will need work for the new core paradigm.
931 Opcode patches from the net:
933 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
934 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
935 missing altogether - they are added here. From Bruce Bauman.
936 * mips-opcode.h: The low mask for C0 instructions was too small.
937 From Garrett Lau. I modified the fix to check the entire 32-bit
940 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
943 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
945 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
947 * dbxread.c (read_type): Pointer subtraction (value_sub in
948 valarith.c) sometimes failed because the types of the
949 pointers being subtracted were not identical.
950 These differed because dbxread.c was allocating pointer types
951 using dbx_alloc_type+smash_to_pointer_type instead of
952 lookup_pointer_type. I failed to find a justification for the
953 former, so I changed it to use the latter. Similarly, I
954 replaced smash_to_function_type by lookup_function_type,
955 and smash_to_reference_type by lookup_reference_type.
957 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
958 _initialize_mipsread): corresponding changes.
960 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
962 * source.c (mod_path): Do tilde_expand on each component of the path,
963 rather than on the (list of) paths as a whole.
964 (print_source_lines): Set first_line_listed in addition to
965 current_source_symtab and current_source_line. If the source was
966 not findable, after a "dir" command to fix the problem,
967 a "list" would get the wrong lines.
969 While I was there... (gnu):
971 * dbxread.c (read_type): Change error to complaint.
973 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
975 First attempt at detailed understanding of symbol table memory alloc.
977 * dbxread.c (dbx_symfile_read): Free our string table if we
978 aren't the mainline. Free the "info" struct since we're done with
980 (init_psymbol_list): Free any previously allocated psymbol lists.
981 (): FIXME: Should realloc-down the psymbol lists when done reading

987 (REGISTER_ADDR): Make result type unsigned int.
989 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
990 define REGEX must also define REGEX1 (its dependency).

1027 in raw hex as well as float format, regardless of whether it is
1028 a "virtual" convertible register.

1030 regs as a double, just in case it's being used that way.
1031 * values.c (unpack_long): Comment on array/function coercion.
1032 (unpack_double): Argument is in target byte order now. For
1033 integer arguments, just call unpack_long and float the result.

1035 * remote-nindy.c: Use ieee-float stuff.
1036 (nindy_fetch_registers): Unpack double regs to host double, then

1050 Changes from a bringup on the DEC Vax under Ultrix 4.0.
1052 * coredep.c (fetch_core_registers): Pass end-address of register
1053 section to register_addr as expected. Don't call supply_register
1054 if we'd just pass it garbage.
1056 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
1058 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.

1103 * inftarg.c (child_detach): Pop the child_ops vector if the
1104 detach is successful.
1105 * remote-nindy.c (nindy_create_inferior): Don't push a new
1106 nindy_ops since nindy uses the same one for execution and memory
1108 * core.c (core_ops): Use child_attach and child_create_inferior
1109 rather than default attach and create_inferior functions.
1111 Handle floating point registers in core files.
1113 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
1114 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
1115 This version untested since BFD doesn't yet support sun3 core
1117 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
1118 conventions. Fix comments and style. This version has not
1119 been compiled yet, since we have no HP inhouse.
1120 * core.c (get_core_registers): Look for two sections, ".reg"
1121 and ".reg2", and pass both to fetch_core_registers sequentially.
1123 Revise directory path yet again.
1125 * source.c (forget_cached_source_info): Not static any more.
1126 (init_source_path): New default source path is "$cdir:$cwd".
1127 (dir_command): Handle variable arguments ($cdir, $cwd).
1128 (source_info): Print "Compilation directory" rather than
1129 "Originally compiled in" to remind people of $cdir.
1130 (openp): If the path contains $cwd, use current directory.
1131 (open_source_file): If compilation directory is known, replace
1132 first $cdir in path with the compilation directory.
1133 (print_source_lines): Even if we can't print the lines, set the
1134 current symtab and line for future commands like "info source" or
1135 "breakpoint". Also, error message now contains the file name,
1136 line number, and file access error message.
1137 (_initialize_source): Fix help text to describe changes.
1138 * main.c (cd_command): Forget cached source info when we chdir.

1143 * coffread.c (read_one_sym, init_linetable, init_stringtab):
1144 Byte-swap COFF symbol tables if necessary when reading them in.
1145 Use complain() to replace error message in one spot. Needs
1146 corresponding change in bfd/coff-code.h to make some symbol
1147 swapping routines non-static.
1149 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)

1161 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
1163 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
1164 <rpc/rpc.h> and <rpc/types.h>.
1166 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
1168 * i960-tdep.c (examine_prologue): Add new argument limit,
1169 which stops the scan at the end of the prologue, or at the PC.
1170 This fixes a problem where it walks down into the code for the
1171 user's statements if that code looks like function prologues.
1172 Mark Fox and I have been bouncing this code back and forth, making
1173 small changes to it. Callers changed to match.
1175 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
1177 Cleanup for gdb-3.94 release final:
1179 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
1180 the .c files from vx-share and nindy-share, from the various
1181 macros, since they are not found via ALLDEPFILES.
1182 (SFILES): Add tm-i960.h.
1183 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
1184 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
1186 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
1187 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.

1191 * am29k-tdep.c: Add contribution line.
1192 (examine_prologue): Cache information about function prologues in
1193 the misc-function-vector to avoid lots of references over the
1194 serial line while examining instructions.
1196 * core.c (core_close): New function made from cleanup_core.
1198 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1199 remote-vx.c, remote.c, target.c, target.h,
1200 Update target_ops vector to add attach, close, and load entries.
1201 Use add_syms_addr_command, not add_file_addr_command, for
1202 add_file. Break out close routine from existing code.
1204 * dbxread.c (really_free_pendings): Don't free pending_blocks;
1205 they are in an obstack.
1206 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
1208 (define_symbol): Add symbol type parameter; change callers;
1209 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
1210 it to influence the symbol class on the i960.
1211 (define_symbol): Swap LOC_CONST's into target byte order.
1213 * exec.c (exec_close): New function.
1214 (exec_file_command): Call it.
1216 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
1217 Fix byte order of frame pointer.
1218 (read_var_value): Result of 0 if var's value can't be found,
1219 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
1220 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
1221 (locate_var_value): Use read_var_value and use its lazy address
1222 as the location of the var's value. Lint.
1224 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
1227 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
1228 obsolete Intel versions in favor of vxgdb versions.
1229 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
1230 code dealing with byte order of values, which Intel did in host byte
1231 order rather than gdb-4's target byte order.
1232 (i960_frame_chain_valid): Move to nindy-tdep.c.
1233 (examine_prologue, skip_prologue, frame_find_saved_regs,
1234 frame_args_address, leafproc_return, saved_pc_after_call,
1235 pop_frame): Add vxgdb versions from Mark Fox.
1236 (examine_prologue, frame_struct_result_address): Add code
1237 to deal with the saved value of G13 (struct return address
1239 (frame_args_address): Modify Mark's version to prefer the
1240 saved value over the current value in the topmost frame.
1241 Cache result in the frame info to avoid performance hair in
1243 (print_fault): Add gdb960 code for printing faults.
1244 (_initialize_i960): Actually call check_host.
1246 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
1247 add stub routines. FIXME, these currently just return zero!
1249 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
1250 (attach_command): Call target_attach, not target_open, now.
1252 * infrun.c (normal_stop): Make global, not static, for vx_attach.
1253 (child_attach): Rename from child_open.
1254 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
1255 don't confuse it with a zero step_resume_break_address.
1257 * inftarg.c (child_detach): Eliminate inferior_pid test.
1258 (child_files_info): Clean up message a bit.
1259 (child_ops): Use child_attach, not child_open, to attach.
1261 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
1262 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
1263 findvar.c to here, since it depends on the contents of the
1264 shadow_contents of breakpoints, but keep if #if 0 since it is
1267 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
1270 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
1271 (ptype_command, display_command): Eliminate have_inferior_p and
1272 have_core_file_p in favor of target_has_stack or
1273 target_has_execution.
1274 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
1275 code for actually finding the values of arguments, though we still
1276 keep track of the maximum stack offset for use in printing unnamed
1277 arguments. Handle missing FRAME_ARGS_ADDRESS.
1279 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
1280 (struct nindy_regs): Define registers passed to/from nindy.
1281 (nindy_fetch_registers, nindy_store-registers): Translate between
1282 nindy and GDB formats for the registers.
1283 (dcache_init): Statically allocate the cache, since it was being
1284 allocated by a malloc that was never freed anyway.
1285 (nindy_create_inferior): Error, not core dump, if no exec file.
1286 (nindy_before_main_loop): Use target_load, not target_add_file.
1288 * remote-vx.c (net_load): Specify large timeout for load
1289 requests. Allow user to break out with INTERRUPT.
1290 (net_break): Remove useless code, clean up. Change callers.
1291 (parse-args, skip_white_space, find_white_space): Clean up arg
1292 parsing to cope with quoted strings.
1293 (net_wait, net_quit): Never call error, just return status.
1294 (vx_read_register, vx_write_register): Cleanup status checking.
1295 #ifdef the code based on which CPU we are using (960 or 68k),
1296 FIXME, this should be completely general but it isn't yet.
1297 (vx_xfer_memory, vx_resume): Cleanup status checking.
1298 (vx_run_files_info): Improve message.
1299 (vx_load_command): Renamed from vx_add_file_command. Allow load
1301 (net_ptrace): Remove unused routine.
1302 (vx_wait): Adopt code from vxgdb960 to cope with broken
1303 connections to target machine and prompt to disconnect. Remove
1304 debug printouts. Map some EVENT_'s to SIGnals.
1305 (add_symbol_stub, vx_open): Print names of object files we found,
1306 and "ok" if we read their symbols OK. Clarify output in general.
1307 (vx_attach, vx_detach, vx_kill): Add these commands.
1308 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
1309 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
1310 "info files" output, and create_inferior, since we already have
1313 * stack.c (frame_info): Replace Frame_unknown with 0.
1314 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
1315 (return_command): Pop until the PC matches as well as the FP,
1316 so it works even if the FP is shared with another function,
1317 as in "frameless" or "leaf" procedures.
1319 * symfile.c (load_command): renamed from add_file_target_command.
1320 (add_syms_addr_command): renamed from add_file_addr_command.
1321 (add_syms_command): Stub to call target_add_syms.
1322 (_initialize_symfile): Change command names and descriptions,
1323 add-file => add-syms, and load from alias to its own command.
1325 * target.c (kill_or_be_killed, maybe_kill_then_attach,
1326 maybe_kill_then_create_inferior): Default for attempts to start
1327 a process, if one is already running, is to ask about killing
1328 it and retry if yes.
1329 (upstack_create_inferior): #if-0 it, strata obsolete it.
1330 (push_target, unpush_target, pop_target): to_close() a target
1331 before unstacking it.
1332 (target_info): Renamed from target_files_info.
1333 (_initialize_targets): Rename "i files" as "i target", accessible
1336 * target.h: Improve comments about the target_ vectored routines.
1338 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.

1341 (SKIP_PROLOGUE): No longer a no-op.
1342 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
1343 (*_REGNUM): Sort register numbers.
1344 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
1345 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
1346 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
1347 are now 10 byte extendeds, not 8 byte doubles.
1348 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
1349 for nindy versus vxworks targets. FIXME, this should possibly go
1350 in the target vector.
1351 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
1352 frame_saved_regs and arg pointer with each frame.
1353 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
1354 (FRAME_ARGS_ADDRESS): Use cached result.
1355 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
1356 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
1357 (PRINT_RAMDON_SIGNAL): Call print_fault.
1358 (POP_FRAME): Now works.
1360 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
1361 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
1362 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
1363 (ADDITIONAL_OPTION_HANDLER): use target_load, not
1366 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
1367 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
1369 * valarith.c (value_subscripted_rvalue): Avoid handling
1370 floats and doubles specially; it gave alignment errors. Lint.
1372 * valops.c (value_of_variable, value_of_this): Error if unknown
1375 * valprint.c (print_floating): Bcopy rather than pointer-deref,
1376 to avoid alignment problems.
1377 (value_print): Handle unknown value address.
1378 (cplus_val_print): Two args are ignored; remove them. Change caller.
1379 (val_print): Use unpack_long rather than pointer-deref.
1382 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
1383 to avoid alignment problems.
1384 (value_being_returned): Error if return value unknown.
1385 (set_return_value): Add bogosity warning, FIXME. *
1387 * TODO: A woman's work is never done.
1389 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
1390 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
1391 Add ieee-float.o to OBS.
1392 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
1393 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
1394 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
1396 Changes to generalize the VxWorks RPC protocol slightly, to handle
1397 i960 as well as 68000.
1399 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
1400 * vx-share/reg.h: Produce i960 regs #ifdef I80960
1401 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
1402 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
1403 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
1404 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
1405 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
1406 so they will move in target byte order rather than network
1407 byte order (happens to be the same).
1409 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1411 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
1413 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1416 Add contribution lines to various files, showing where they
1419 * breakpoint.c (break_insn, check_break_insn_size,
1420 read_memory_nobpt): Remove to mem-break.c.
1422 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
1425 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
1426 entry has bad register number. This change is not
1427 tested in this release, FIXME.
1429 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
1432 * value.h: Force value's contents field to be aligned to hold
1433 at least a double or a long long (if supported). This avoids
1434 doing bcopy's in and out of the contents field.
1436 (step_1): Avoid coredump under obscure circumstances when we
1439 * symtab.h (misc_info): Add field to misc function vector for
1440 any kind of cached information the target code desires. AMD
1441 29000 uses this to avoid repeating examine_function_prologue's.
1443 * coffread.c: Lint. Remove static symfile, read_section_header.
1444 core.c (have_core_file_p): Lint: remove.
1445 expprint.c (print_subexp): Lint.
1446 infptrace.c, valops.c, valprint.c: lint.
1448 Roll in changes from vxgdb-5.0.1:
1450 * symtab.h: Comment byte order of each address class. Add
1451 LOC_LOCAL_ARG for frame-relative args (960).
1452 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
1453 symtab.c, symmisc.c: ditto.
1455 * infrun.c (init_wait_for_inferior): Clear stop_signal.
1457 * remote.c (remote_resume): Error if resume with a signal.
1459 * symfile.c (prim_record_misc_function): Clear misc_info.
1460 (fill_in_vptr_fieldno): Check stub type of arg.
1462 * valops.c (value_cast): Avoid looking up names of types whose
1463 name we don't know, to prevent coredump. Sun CC produces typedef
1464 rtx and the name of *rtx is zero...
1466 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1468 Roll in changes from final AMD 29000 port (Tiemann).
1470 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
1471 for ../include/a.out.encap.h. This might not work now that BFD
1472 is separately compiled. Instead, BFD support for encap will have
1473 to translate machine type 29k into the right COFF_MAGIC.
1475 * infcmd.c: Remove references to inferior_pid that aren't used
1476 in actual ptrace calls; use target_has_execution, etc.
1477 (have_inferior_p): Remove function.
1478 (program_info): Print target info rather than "process number";
1479 avoid gratuitous messages unless from_tty.
1480 (run_stack_dummy, finish_command): Set proceed_to_finish.
1481 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
1482 main.c: Lint. Lose have_inferior_p().
1483 inferior.h (have_inferior_p): Remove, lint.
1484 (proceed_to_finish): Add flag to ask that all regs be saved
1485 by normal_stop, for the few commands that need it, speeding up
1486 serial I/O. Add comments to stop_registers.
1488 * remote-eb.c: Remove newline from breakpoint message we grep
1489 for. Never time out when running the user program.
1493 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
1495 Roll in changes from vxgdb-5.0.1:
1497 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
1498 symbol in its raw form, we are processing an unlinked ".o" file.
1499 See if the target environment has assigned it an address, using
1500 target_lookup_symbol (VxWorks does), and enter it into the symtab
1503 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
1504 68k versions for a simpler version that assumes zero FP at bottom.
1505 Fixes bug of truncated stack reports.
1507 * target.h (target_lookup_symbol): Define this routine's args
1508 and result, finally.
1510 * target.c (nosymbol): Default routine for target_lookup_symbol.
1511 (target_default): Default lookup_symbol and call_function too.
1512 (files_info): Only print has_all_memory warning if a non-dummy
1515 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
1516 vx_convert_from_virtual): If target does not have floating point,
1517 zero register "values", and avoid doing cross-net conversions.
1518 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
1519 (vx_open): Rearrange code that attaches to target and reads
1520 symbols for all loaded modules, to work if some of the modules
1521 are not accessible. Add symbol_stub() and add_symbol_stub()
1522 as callbacks from catch_errors(). Allow connect attempt to be
1523 interrupted painlessly with ^C (FIXME, there are still some bugs
1524 if the interrupt happens during symbol reading.). Print
1525 final message with puts_filtered, since symbol messages are
1530 * main.c (catch_errors): Only print errstring if non-null.
1531 (command_loop): Avoid an ioctl per command to test ISATTY.
1533 * remote-vx.c (net_load): make static; avoid sophomoric msg.
1534 (vx_xfer_memory): Return correct result!
1535 (vx_files_info): Indicate whether target has float or not.
1536 (vx_lookup_symbol): Complain, not error, if target gone.
1537 (vx_open): Print "Connected" msg before disabling immediate-quit.
1538 [FIXME: lookup_symbol and vx_open changes need testing.]
1540 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
1541 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
1542 contributor lines and update copyrights to 1991.
1544 Changes from an attempted H-PUX host port:
1546 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
1547 defines PT_ATTACH and PT_DETACH but not PT_KILL.
1548 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
1549 * remote-vx.c: include <sys/time.h> for HPUX.
1550 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
1551 "core_file_command" routine to BFD regime. May not work yet.
1553 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
1555 * xgdb.c: Replace X10 version with some VJ version.
1556 (FIXME: Its copyright assignment is not on record.)
1557 * xgdb.c: Update include files to X11R4 (Xaw crud).
1558 (xgdb_display_source, create_text_widget): fix call to
1559 get_filename_and_charpos. Rewack source window stuff for X11R4
1560 (gleaned from include files, and "nm's" of binary libraries, since
1561 I had no doc available).
1562 (append_selection, append_selection_word): Disable with FIXME
1563 since R4 changed interface here.
1564 (create_buttons): Add back the old set of buttons.
1565 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
1567 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
1568 Roll VERSION to 3.94 (not yet final though).
1570 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1572 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
1573 obstack_int_grow, obstack_int_grow_fast): Eliminate
1574 cast on left of assignment, which gives MIPS cc fits and is
1577 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
1578 F_ALIAS. Use printf, not fprintf, when not passing a file
1580 (compare_opcodes): Check that identical instructions have
1581 identical opcodes, complain otherwise.
1583 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
1584 was reported by Roland McGrath.
1585 (unimp): Only match if exactly zero instruction. (Roland)
1586 (branches and traps): Generate all variations of these
1587 instructions with macros, based on a single call that defines
1588 each condition name and its binary representation.
1589 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
1591 * valprint.c (val_print_fields): Take, and use, format parameter.
1592 This means that "p/x struct" again prints the elements in the
1593 desired format. Changed callers.
1595 * stack.c (frame_info): Use filtered output, and indicate wrap
1596 points. Remove kludgy formatting designed to avoid line wrap.
1598 * utils.c (wrap_here): If the line is already full (because
1599 we had printed a long indent or long wrapped string), do an
1600 immediate newline-and-indent.
1602 * m68k-pinsn.c (print_insn_arg): Bugfix from
1603 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
1604 instruction is incorrectly disassembled as bkpt #8.
1606 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
1607 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
1608 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
1609 and then will dump core (sometimes). I traced it back to an
1610 uninitialized symfile_name in psymtab_to_symtab.
1611 (const_vol_complaint): Add quotes to message.
1612 (define_symbol): Only believe line number if gcc_compiled.
1613 Avoid allocating symbol if we will not return it.
1615 Add target strata support so that newly established targets go
1616 into their right place in the target stack (e.g. a new exec file
1617 doesn't wipe out the ability to access the running process).
1619 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
1620 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
1621 and initialize it properly in all the targets.
1623 * target.h: Document strata. Change return type of push_target.
1625 * target.c (nomemory): new function for dummy memory access.
1626 (tcomplain): Rename complain, now also used in symfile.c.
1627 (push_target): Push targets within strata. New return value shows
1628 whether new target is on top of stack or not. Always keep dummy
1630 (target_files_info): Ignore dummy target.
1632 * core.c (core_open): Warn user, and skip accessing file, if the
1633 core target is not the topmost target in the stack.
1634 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
1637 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
1638 target_ops, it doesn't belong there since we have no regs there.
1639 Change name of target from machine => memory to clarify.
1641 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
1643 * Freeze version 3.93 for release.
1645 * Makefile.dist: Handle vx-share and nindy-share subdirs
1646 properly when building gdb.tar.Z.
1648 * symtab.c: lint; add no_symtab_msg to consolidate the messages
1649 printed in various places, so I could change just one copy.
1651 * dbxread.c, coffread.c: Change references to bfd->iostream
1652 to cast to FILE *, now that BFD avoids needing types defined
1653 in other header files.
1655 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
1657 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
1658 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
1659 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
1660 (actually gcc -Wall).
1662 * dbxread.c: Remove first_global_sym, last_global_sym, since
1663 they are never referenced.
1665 * defs.h (baud_rate): Declare.
1666 main.c: Define it, and add the -b option to set it.
1668 * gdb-int.texinfo: Add text on how to define a new host or target
1669 architecture, prompted by Per Bothner's questions about MIPS
1672 * gdb.texinfo: Document "complaints". Change doc of -q since
1673 gdb no longer prints the copyright and blurb if you specify a file
1674 name to be debugged (just like Emacs). Add doc for Nindy-specific
1675 command line flags for specifying target serial port and such.
1676 Update copyright to 1991.
1678 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
1679 has taken over for us the job of ripping up executable files. The
1680 crud caused Per Bothner's port to not compile.
1682 * infrun.c (normal_stop): Avoid printing "Program exited
1683 normally" if we are in batch mode. This allows a GDB which
1684 executes a program on a target system, to behave like a Unix
1685 command (input from stdin, output to stdout, no extraneous
1688 * main.c (main): Allow additional machine-dependent command line
1689 options to be specified with the ADDITIONAL_OPTIONS,
1690 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
1691 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
1692 processing to occur just before the main loop with
1693 BEFORE_MAIN_LOOP_HOOK.
1694 (main): If a "core file" argument is specified, and it is not a
1695 core file, try it as a process ID to attach.
1696 (symbol_completion_function): Attempt to cope with
1697 "show screen-" TAB, not very successfully. This needs more work,
1699 (batch_file): New function, returns whether we are reading
1700 commands from an interactive tty on stdin, or from somewhere else.
1701 Called by normal_stop since it doesn't get from_tty passed down
1702 to it like many commands do.
1704 * remote-nindy.c: Handle command line options for nindy
1706 (nindy_before_main_loop): Prompt user for tty name if they
1707 don't specify it before getting to the interactive command loop.
1709 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
1710 and -r command line options. Also add hook before main loop
1711 to make it easy to specify a tty.
1713 * TODO: More things to do, one done.
1715 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
1717 * dbxread.c: Make complaint() calls pass pointer, not struct.
1718 Add complaints about badly formatted C++ type information
1719 (const/volatile indicator, and parse errors resulting in
1720 error_type). Fix C++ virtual member fn comment.
1721 (read_struct_type): Avoid bumping pointer if we got a parse
1722 error; this prevents our walking beyond the end of a string.
1723 Terminate loop on null char as well as semicolon.
1724 (process_one_symbol): Fix the LBRAC fix so that it uses the
1725 last previous SLINE, FUN, or SO record's PC address. C++ debug
1726 symbols did not have SLINE records in a useful order compared
1727 to the LBRAC records.
1728 (define_symbol): Handle "catch" records.
1730 * symtab.c (check_stub_type): Added new complain
1731 `stub_noname_complain' and added a consistency check to
1732 keep the debugger from crashing when finishing from an
1733 exception frame. A real fix will be needed later.
1735 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1737 * infcmd.c (attach_command): Make global.
1739 * Makefile.dist (REMOTE_OBS): Make these compile by default,
1740 but make them easy to comment out. Perhaps later they should
1741 be enabled by what CPU you configure for? FIXME.
1742 (VERSION): Roll to 3.93.
1743 (pinsn.o): Remove rule for obsolete file.
1744 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
1746 Run down a problem that manifested by printing the wrong function
1747 name in stack traces of read_ofile_symtab. Turned out that the
1748 problem was the SunOS 4.1.1 (and previous) C compiler outputs
1749 the LBRAC symbol with an address in the *data* segment, which
1750 blew our binary search through the blocks.
1752 * dbxread.c: Use the complain() facility consistently to bitch
1753 about problems in the symbol file we are reading.
1754 (finish_block): Add code to check the nesting of the blocks;
1755 complain and Procrust them to fit if wrong.
1756 (make_blockvector): Check the order of the blocks, complain
1757 [but don't cope] if wrong.
1758 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
1759 symbols to be sure their PC value is greater than the last SLINE
1760 (line number) symbol we've seen, complaining and adopting the
1761 SLINE PC value if wrong.
1763 * symfile.h (struct complaint, complaint_root, complain,
1764 clear_complaints): Add.
1765 * symfile.c (complain, complaint_root, clear_complaints): Add
1766 facility to deal with non-fatal complaints and to regularize their
1768 (symbol_file_add): Clear complaint counters to allow new complaints.
1769 (initialize_symfile): Add 'set complaints' and 'show complaints'.
1771 * dbxread.c (dbx_symfile_read): Remember the address and size
1772 of the string table for the main symbol file, so we won't read it
1774 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
1775 to avoid reading the string table yet again. Lint.
1776 (throughout): Improve filtered output, including word wrap.
1777 (read_range_type): Improve Bothner's fix to handle other types too.
1779 * utils.c: Improve line wrap implementation. Handle unlimited
1780 width by making chars_per_line unsigned.
1781 (puts_filtered): New, easy, function.
1783 * defs.h (puts_filtered): add.
1785 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
1786 call the identical sort_symtab_syms() in symfile.c instead.
1788 * expread.y: Suggest the `file' command rather than `symbol-file'.
1790 * command.h (enum var_types): Add zinteger for seroable
1792 * command.c (do_setshow_command): Handle var_zinteger. Restructure
1793 nested if's into a switch.
1795 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
1796 we did not stop because of a breakpoint (it must have been for
1797 some other reason, like a "stepi"), so don't print anything.
1799 * symtab.c: Include <sys/types.h> all the time. Now that BFD
1800 doesn't include <sys/types.h>, old SunOS's require it for
1803 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
1805 A test port of gdb-3.92.6 to the Sony NEWS.
1808 Don't normally link in remote- or vx stuff.
1809 Some of it doesn't compile, and it wastes space for 99% of the users.
1810 Remove reference to no-longer-used HAVE_VPRINTF.
1811 Fixed BFD_DEP typo to BFD_DIR.
1813 Fix cast in arg to bfd_h_getlong.
1814 Make char *prefix be const.
1815 Fix how certain range types are mapped into builtin unsigned int types.
1817 Remove 2 #includes. They cause errors (on Sony, at least),
1818 and aren't needed (they wern't in earlier versions).
1820 print_address_symbolic should never demangle labels
1821 (since it prints *assembler-level* labels).
1823 [This was superseded by the change to printcmd below.]
1826 Add some "volatile" return types to avoid warnings.
1827 If MISSING_VPRINTF add vprintf function and not just macro
1828 (since vprintf is used in printcmd.c).
1830 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
1831 (The latter isn't grokked by some PCC-based compilers.)
1833 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
1835 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
1836 * nindy-share/coffstrip.c
1837 Added some forward declarations (otherwise, gcc complains
1838 about implicit extern redefined as static).
1840 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1842 Changes inspired by Per Bothner:
1843 * printcmd.c (print_address_symbolic): Take additional parameter
1844 specifying whether to demangle.
1845 (print_address): Pass in asm_demangle to control demangling.
1846 (print_address_demangle): New fn, takes explicit arg to control
1848 * utils.c: Add new vars demangle and asm_demangle, and let them
1850 (fputs_demangled): If !demangle, just print the argument.
1851 (fprint_symbol): If !demangle, just print raw symbol.
1852 * valprint.c (val_print): Call print_address_demangle rather than
1853 print_address, to cause demangling to depend on the global
1854 rather than assembler-level demangling setting.
1855 * WHATS.NEW, gdb.texinfo: Document.
1857 * main.c (show_command): Show all settings if no arg.
1858 (initialize_main): Make "info set" the same as naked "show".
1859 * command.c (cmd_show_list): Handle prefix commands in the
1860 list, and print the name of the setting as well as its English
1861 description and value.
1863 Allow gdb functions to specify where a line should wrap if it
1864 exceeds the size of a terminal line. Use it to make the output
1866 * utils.c (set_screen_width_command): New fn, mallocs a buffer
1867 of the right size when screen width changes.
1868 (set_screensize_command, screensize_info): Remove #if 0'd fns.
1869 (wrap_here): New fn, indicates a point in the output where we
1870 should wrap the line rather than just letting it overflow at a
1872 (fputs_filtered): Implement wrapping.
1873 (n_spaces): New fn, returns a pointer to N spaces.
1874 (print_spaces_filtered): Use n_spaces.
1875 * defs.h (n_spaces): Declare.
1876 * stack.c (print_frame_info): Wrap with 4-space indent after
1877 fn name and before filename and line number.
1878 * printcmd.c (print_frame_args): Wrap with 4-space indent
1879 before each argument name is printed.
1880 * valprint.c (value_print): Wrap with no indentation before
1882 (val_print_fields): Wrap with indentation relative to nesting
1883 level before each field name.
1884 (val_print): Wrap with nesting indentation before array elements.
1885 * command.c (do_setshow_command): Avoid extra newlines,
1886 wrap with 4-space indent around values printed, end with period.
1887 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
1889 * breakpoint.c (breakpoint_1): Implement addressprint for
1890 "info breakpoints" display. Change file name and line number
1891 format to " at file:nnn" rather than " (file line nnn)".
1892 * gdb.texinfo: Document.
1895 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1897 Frozen for gdb-3.92.6 release.
1899 README, WHATS.NEW: Update for 3.92.6 release.
1901 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
1902 coffread.o from configs since it is now built by default.
1903 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
1904 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
1905 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
1906 from configs since it is now built by default.
1908 Makefile.dist: Update for release 3.92.6. Handle files that
1909 have been moved to ../include, ../getopt, or ../bfd. Add
1910 saber.suppress and tests directory. Add config.status to
1911 the release (it will say "none").
1913 coredep.c: Minor formatting fixes.
1915 These changes were made in early December but only checked in now:
1916 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
1917 nindy-share/nindy.c: lint
1918 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
1919 register values coming back from the target; we store values
1920 in target byte order everywhere.
1922 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
1924 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
1926 * valprint.c (cplus_val_print, val_print_fields): New functions,
1927 which print C++ objects. They conspire to avoid printing a
1928 virtual base class more than once, following all the twists and
1929 turns of C++ virtual base rules.
1930 (val_print): Call the above rather than do it by hand.
1932 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
1933 symbol file, not for added files like shared libs. This really
1934 needs to be generalized to a timestamp per file.
1936 * core.c (cleanup_core): Avoid coredump if no core file.
1938 * config.gdb: Accept -host or -target in place of +host or
1941 * coffread.c (find_linenos): Avoid desupported BFD interface
1942 to line numbers. We still read them manually rather than using
1943 BFD's "generic" features.
1945 * gdbrc.tex, threecol.tex: Add GDB reference card and its
1947 Makefile.dist: Add refcard to OTHERS list for creating tar files.
1949 * Makefile.dist: Eliminate use of $< in explicit targets.
1951 * readline/Makefile: Use $< rather than $*.c, which does not
1952 include the VPATH in GNU Make.
1954 * tconfig/i960-bout, tconfig/i960-coff: These are identical
1955 copies of tconfig/i960, added for global configuration
1956 compatability. All i960 versions can read both coff and b.out.
1958 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
1959 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
1962 * TODO: Think of more things to do.
1964 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
1966 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
1967 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
1968 64-bit float conversion.
1970 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
1971 equivalent to sun?os4 so global config works.
1973 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
1975 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
1977 * main.c: Only declare linesize once; declare pagesize not at
1978 all, since it is never used.
1979 (main): Clear newly allocated line before it is used.
1981 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
1983 Further stabilization for the Intel 960.
1985 * Makefile.dist: Parameterize the location of the "include"
1986 and "bfd" directories, as well as "getopt". Add symfile.c.
1987 Link in both dbxread and coffread. Fix up "make depend" to
1988 rewack the locations of include, bfd, and getopt in its output.
1990 * README: Document moving include files, improve some of
1993 * coffread.c: Move common code out to symfile.c. Change
1994 symbol_file_command style interface to use new *_symfile_init
1995 and *_symfile_read interface under BFD. Use BFD internal
1996 info to locate line table, symbols, etc.
1998 * core.c (core_fetch_registers): Rename to get_core_registers
1999 to avoid confusion with fetch_core_registers.
2000 (register_addr): Move to coredep.c, which is already machine
2001 dependent. This leaves core.c pretty clean of dependencies.
2003 * coredep.c (register_addr): Accept this routine from core.c.
2005 * dbxread.c: Move common code (with coffread.c, etc) into new
2006 symfile.c. Each psymtab now contains a pointer to the
2007 format-dependent function that knows how to read it in. Make
2009 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
2010 (process_one_symbol): Add code to complain about a "compiler bug
2011 we muzzle here", if we actually see it.
2013 * eval.c (evaluate_subexp): Insert missing "break" statements
2014 in code that determines whether a variable is an lvalue in
2015 memory, register, or whatever. I detected this via a compiler
2016 bug in which it *almost* mashed out the whole switch statement.
2018 * gdb-int.texinfo: Add minor sections on configuring gdb for
2019 release, and about the README file.
2021 * infcmd.c (registers_info): Fix formatting somewhat. Still
2022 not as pretty as before, but it handles byte swapping.
2024 * remote-nindy.c: If data cache routines are interrupted while
2025 waiting for the remote end, be sure that any uninitialized cache
2026 blocks are on the free list, not on the valid list!
2028 * symfile.h: Flesh out this header file with all the various
2029 routines and variables that have been merged in from dbxread.c
2030 coffread.c, and symtab.c to symfile.c.
2032 * symfile.c: New file, containing code common to dbxread.c,
2033 coffread.c, and some code from symtab.c. All generic code for
2034 reading symbol files should be in here now.
2035 (unrecord_misc_function): Remove unused function.
2037 * symtab.h: Remove file-reading things to symfile.h.
2039 * symtab.c: Remove file-reading things to symfile.c.
2041 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
2042 to decode i960 fault types.
2044 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
2045 target.c: Change type of the "resume" function from int to void,
2046 since its result was never used.
2048 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
2050 * main.c: Replace "stupid" with "caution"; you now "set caution
2053 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
2055 * infcmd.c (do_registers_info): Call val_print to deal with the
2056 byte order of the registers being printed. FIXME, this makes
2057 the formatting of the output uglier.
2059 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
2060 defined, call it for signals the debugger doesn't itself use.
2061 The i960 uses this for more detailed fault information.
2063 * remote.c (remote_open): If arg is null, print help rather than
2066 * sparc-xdep.c (register_valid): Avoid declaring size, since
2067 various modules will think of various sizes depending on the
2068 architecture of their tm-file. FIXME, we need protection against
2069 actually entering one of those modules, which would clobber
2070 storage if not for the target architecture compiled into gdb.
2072 * stack.c (up_command, down_command): Always print the frame
2074 (up_silently_command, down_silently_command): New commands
2077 * i960-pinsn.c (reg), i960-tdep.c: Lint.
2079 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
2080 more parameters than it used to.
2082 * findvar.c (registers): Increase slop to 256 bytes, which should
2083 protect us against even most RISC machines with large register
2085 (locate_var_value): Move declaration inside related ifdef.
2087 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
2088 throughout, to avoid throwing away buffered input from the board.
2089 (nindy_wait): Supply_register takes addr_of_value, not value.
2090 (i960_print_fault): Renamed from i80960_fault.
2091 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
2092 (nindy_store_registers): Avoid regs_changed stuff, just stuff
2094 (nindy_create_inferior): Don't bother to write PC_REGNUM since
2095 we can set the PC in the call to proceed(). Unpush nindy_ops
2096 before pushing it on top, to avoid message to user. Eliminate
2097 commentary from Unix machines that just misleads here.
2098 (reset_command): Fix error message to suggest target command.
2100 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
2102 Release 3.92.5 as frozen.
2104 Stabilize the merged release...with help from lint, Saber C,
2107 Everywhere: Add include files needed to declare return types
2108 of functions called.
2110 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
2112 * breakpoint.h: Add undeclared breakpoint functions, and some
2113 functions for display handling since I couldn't think of a better
2116 * breakpoint.c (insert_breakpoints): Make code for disabling
2117 shared library bkpts more likely to work. It's used when we
2118 rerun a program and stop before the shared library has been
2120 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
2121 cast from pointer, so it squeezes through catch_errors.
2122 (bpstat_stop_status): Fix logic broken some time ago. We now
2123 always create a bpstat if the stop address matches a breakpoint,
2124 even if we don't stop there -- just like the old code used to do
2125 before I got my fingers into it (sigh).
2126 (breakpoint_1): Print "ignore count" after "stop only if"
2127 condition, since that's how it actually works.
2128 (mention): Handle watchpoints as well as breakpoints.
2129 (watch_command): use set_raw_breakpoint and mention to do most
2130 of the work (and initialize all the fields!). Only pass one
2131 arg to parse_c_expression, since that's all it takes.
2133 * command.c (not_just_help_class_command): Rename arg to args
2134 since we ignore "unused argument" warnings on vars named "args".
2135 inflow.c (child_terminal_info): ditto.
2136 infptrace.c (kill_inferior): ditto
2137 main.c (catch_errors, version_info, quit_command, pwd_command,
2138 source_command, dump_me_command, editing_info,
2139 set_history_size_command, set_history, show_history,
2141 stack.c (locals_info): ditto
2142 target.c (target_files_info): ditto
2143 valprint.c (set_input_radix, set_output_radix): ditto
2145 * core.c: Remove old variables for handling core and exec file
2146 sections (data_start, data_end, stack_start, stack_end,
2147 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
2148 text_end, exec_data_start, exec_data_end, text_offset,
2149 exec_data_offset, data_offset, stack_offset). They're
2150 superseded the more general build_section_table and
2152 (get_exec_file): Mention the `file' command.
2153 (read_memory_check): Rename to memory_error, and only call it
2154 in the case of an actual error.
2155 (read_memory, write_memory): call memory_error.
2156 (core_fetch_registers): Register section name is ".reg".
2158 coredep.c: Remove a bunch of crud now that all this file does
2159 is pull the registers out of a core file.
2160 (fetch_core_registers): Rewrite to actually work, I hope.
2162 dbxread.c: Use a.out.gnu.h, not system a.out, now.
2163 Replace index() with strchr(). Remove all the pre-BFD macro
2164 definitions for accessing the symbol file.
2165 (struct dbx_symfile_info): Encapsulate the information that
2166 dbx_symfile_init needs to pass to dbx_symfile_read in this
2169 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
2170 dbx_symfile_discard): Rearrange symbol file reading to divide
2171 the format-specific part from the format-independent part,
2172 leaving the format-independent part such as file name expansion
2173 and opening in symtab.c. This replaces
2174 partial_symbol_file_open and partial_symbol_file_read.
2175 Symbol_file_read, add_file, add_file_target_command,
2176 add_file_addr_command move to symtab.c. Pass an explicit
2177 "mainline" flag for when reading the main symbol table, rather
2178 than relying on the offset address to be zero or nonzero.
2180 (dbx_symfile_read): Don't allow void *'s to be printed as
2182 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
2183 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
2184 macro" debug version really work.
2185 (read_dbx_symtab): Remove unref'd parameter inclink.
2186 Avoid swapping N_SLINE symbols, for speed.
2187 Merge N_TEXT!N_EXT case with the other external symbol
2188 definitions' case. Add comments.
2189 (start_psymtab): Allocate the symfile name in the psymtab on
2190 the psymbol_obstack, rather than using the caller's storage.
2191 (end_psymtab): Only allocate a dependencies list if there are
2193 (psymtab_to_symtab_2): Use BFD when reopening file to read
2194 its symbols for real.
2195 (read_struct_type): Add FIXME comments where it needs work
2197 (read_huge_number): Add FIXME about overflows.
2198 (read_range_type): Add FIXME about comparing a long to 1<<32.
2200 * coffread.c: Minor changes to move things closer to the new
2201 regime with symtab.c and dbxread.c Major work is still needed
2204 * exec.c (exec_file_command): Remove old variables (see core.c
2206 (xfer_memory): If memory transfer is right at the end of a
2207 section, don't lose.
2209 * findvar.c (get_saved_register): If value is in a real
2210 register, LVAL is lval_register, not lval_memory.
2212 frame.h: Declare print_sel_frame and record_selected_frame.
2214 gdb-int.texinfo: New file, for GDB internals documentation.
2215 Very simple, unformatted doc of cleanups is there for now.
2217 gdbcore.h: Remove obsolete variables that described a.out
2218 section addresses and offsets. (See core.c above.)
2219 Declare fetch_core_registers and registers_fetched.
2221 getopt.c: Declare char *alloca(); even on SPARC.
2223 infcmd.c (run_command): Call target_kill rather than
2225 (step_command, next_command, stepi_command, nexti_command):
2226 Declare from_tty parameter even though we don't use it.
2227 (run_stack_dummy): argument BUFFER is a char array, not
2228 a pointer to REGISTER_TYPE.
2229 (finish_command): using_struct_return needed a value *,
2230 not a struct symbol *.
2232 * infptrace.c (child_xfer_memory): To avoid dependency on
2233 where sections are in memory, try PT_WRITE_D and if that fails,
2234 try PT_WRITE_I. Most Unixes don't care which you use.
2236 * infrun.c (step_resume_break_shadow): Change to array to
2237 match other breakpoint shadow storage.
2238 (clear_proceed_status): Pass address of bpstat to
2239 bpstat_clear, not the bpstat itself.
2240 (child_create_inferior): FIXME comment about if the child
2242 (start_inferior): Remove old function.
2243 (child_open): Use target_kill rather than kill_inferior.
2244 (wait_for_inferior): Ditto.
2245 (insert_step_breakpoint, remote_step_breakpoint): Use
2246 new step_resume_break_shadow.
2248 * inftarg.c (child_wait): If all child processes die,
2249 pretend that the one being waited for exited with signal 42.
2251 * main.c (command_line_input): When scanning for comments,
2252 don't coredump on unclosed quotes.
2253 (quit_command): Use target_kill rther than kill_inferior.
2254 (_initialize_main): Rename class_user from "user" to
2257 * printcmd.c (print_command_1): Initialize "fmt" if no format
2258 is specified by the user.
2259 (print_frame_args): Only add to args_printed if we are
2260 actually fetching args from the stack (avoiding undefined
2262 (_initialize_printcmd): Remove bogus \{ from string.
2264 * remote-eb.c (eb_open): Avoid coredump on no argument.
2266 * remote-nindy.c: Bring out of Intel environment into new
2267 target environment. Remove all conditional compilation on
2268 I80960. Massive hacking throughout.
2269 (nindy_xfer_inferior_memory): New routine stolen from
2271 (nindy_create_inferior): New routine pieced together, probably
2272 not quite working yet.
2273 (nindy_ops): New target_ops struct for nindy.
2275 * remote-vx.c: Use write_memory rather than target_write_memory
2276 to get error checking.
2277 (vx_add_file_command, vx_open): Use symbol_file_add rather than
2279 (vx_create_inferior): Use target_terminal_ours...
2281 * signame.c (_initialize_signame): Always initialize, since
2282 we need the table for things other than psignal.
2284 * solib.c (solib_add): Use symbol_file_add, not add_file.
2285 (solib_address): Return boolean result rather than struct
2286 pointer which nobody else knows the type of.
2288 * sparc-tdep.c, valops.c: Use write_memory rather than
2289 target_write_memory, to get error checking.
2291 * stack.c (locals_info, catch_info, args_info,
2292 get_selected_block, frame_command, up_command): Use
2293 target_has_stack, rather than have_inferior_p or
2296 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
2298 * symfile.h: New file, defining the interface between the
2299 generic and object-file-specific symbol reading code.
2301 * symtab.c: Move generic symbol-reading interface to symtab.c,
2302 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
2303 table to map BFD targets to symbol-reading modules in GDB.
2304 Change index to strchr.
2305 (lookup_struct_elt_type): Use error() rather than hand-made
2306 simulations thereof.
2307 (lookup_partial_symbol): Speedup slightly when length == 0.
2308 (symbol_file_add): New function.
2309 (symbol_file_command): Call it.
2310 (symfile_open, symfile_init): New function.
2311 (add_file_target_command, add_file_addr_command): moved from
2314 * target.c (target_command): use target_kill.
2316 * target.h (target_files_info): Don't declare, never called
2319 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
2320 files to determine stack end address.
2322 * valarith.c (value_x_binop, value_x_unop): Change error message
2323 to be more useful. Pass proper argument to value_struct_elt.
2325 * valops.c (value_assign): FIXME comment that long long
2326 bitfields will break here.
2328 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
2329 Update `make saber_gdb' to work better.
2331 * TODO: A woman's work is never done.
2333 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
2334 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
2335 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
2336 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
2337 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
2338 valops.c, valprint.c, exec.c: Lint.
2341 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
2343 Continuing Intel 960 port merge of GDB.
2345 * Makefile.dist: Merge i960 "nindy-share" files. Rename
2346 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
2347 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
2348 Wack over "make depend" so it handles files in subdirectories
2349 vx-share, nindy-share, bfd, and in the current directory.
2351 * blockframe.c (get_prev_frame_info): Remove fatal error
2352 if stack not defined.
2354 * core.c (core_open, core_detach): New functions that handle
2355 the old "core-file" command as "target core" and "detach" instead.
2356 (core_file_command): Call them.
2357 (core_xfer_memory): Use common routine xfer_memory.
2359 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
2360 dbxread now uses bfd for everything but symbol reading itself.
2361 BFD internals are used to drag out the relevant file offsets.
2362 (partial_symbol_file_open): Change args all around for BFD.
2364 * symtab.c: Rename "value" to "val" everywhere, so we can
2366 (symbol_file_command): New command, moved from dbxread.c
2367 and coffread.c. It uses BFD to read the file, then vectors
2368 based on its type, to dbx or coff symbol readers.
2369 * symtab.h: Extern a few vars for symbol_file_command.
2371 * target.h: Breakpoint takes a char * save area, not a char **.
2373 * valprint.c (val_print): When unpacking bitfields, offset
2374 the address in gdb of the value, if it is declared with a shorter
2375 type. Remove the last "runtime kludge test" of host byte order.
2377 * utils.c: Remove old my_bfd_read routine.
2379 * stack.c (frame_info): Use target_has_stack. Print program counter
2380 register's actual name rather than "pc", since it's called the
2381 "ip" (instruction pointer) on the i960 (sigh).
2383 * target.c (target_command): Add command for selecting a target
2384 type and calling its open routine. This is used for initiating
2385 communication with a particular target, in a generic way.
2387 * tm-i960.h: Update for modern gdb. Remove semicolons from
2388 various macros. Handle reading struct return convention, and
2389 error-out attempts to return structs with the "return" command.
2390 Be sure gdb doesn't think we know how to call functions in the
2393 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
2394 to i960_xxx in lower case.
2395 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
2396 not being defined yet.
2398 * remote.c (remote_open): Call start_remote to initialize
2399 wait_for_inferior during open.
2400 (remote_xfer_inferior_memory): Return length written rather
2403 * remote-vx.c (target_command -> vx_open): Use new generic
2405 * remote-eb.c, inftarg.c, exec.c: ditto.
2407 * infrun.c: Fix comments.
2408 (attach_program -> child_open): Use new generic target command.
2409 (wait_for_inferior): Clear saved register values before target_wait,
2410 so target_wait can set some of them if convenient.
2412 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
2413 Return success indicator, not void.
2414 (child_xfer_memory): Avoid fetching initial word if we'll
2415 overwrite it anyway.
2417 * infcmd.c (attach_command): Use new generic target open routine.
2418 (_initialize_infcmd): Update doc on attach and detach commands.
2419 (do_registers_info): Merge in a byte-order problem as a FIXME
2422 * findvar.c (find_saved_register): Avoid problem in current frame.
2423 (read_relative_register): Ditto.
2424 (write_register): Convert byte order on the way out.
2426 * exec.c (file_command): Add.
2427 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
2428 (xfer_memory): Common function between core_xfer_memory and
2430 (exec_xfer_memory): Use it.
2432 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
2434 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
2435 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
2436 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
2438 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
2440 Merge Intel 960 port of gdb, continuing...
2442 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
2443 symbol_file_command): Pass from_tty arg to hush 'em up.
2445 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
2446 Add magic numbers for 960 COFF format.
2448 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
2450 Merge Intel 960 port of gdb, from Intel "1.2" release.
2452 CHANGE_LOG entries from their port, which was based on

2471 Fri Apr 20 13:47:15 PDT 1990
2474 Thu Apr 19 09:54:28 PDT 1990
2475 Add 'reset' command.
2477 Wed Apr 18 09:48:07 PDT 1990
2478 After opening remote tty, wait for 1 second to go by without input
2479 from it before trying to talk to NINDY (fixes problems with the
2480 Heurikon HK80/V960E).
2482 Mon Apr 4 16:33:05 PDT 1990
2483 Some output was not being suppressed in 'batch' mode.
2485 Thu Mar 22 15:31:11 PST 1990
2486 Ask user if old symbol table should be deleted when new file is
2489 Allow user to run a program downloaded before gdb960 was brought up.
2491 Correct "exec-file" help message for i80960 context.
2493 Correct bug in calculating user space address: could occasionally
2494 corrupt user program.
2496 Make sure to zero low-order bits in rip's because of bug in 960CA
2497 A-step part: could cause operation faults when "next"ing across
2500 Correct bug that made it impossible to get source line numbers for
2501 code loaded at addresses higher than 0x7fffffff.
2503 Wed Jan 10 12:43:22 PST 1990
2504 Open remote tty for exclusive use.
2506 Fri Jan 5 12:14:42 PST 1990
2507 Correct disassembly (CA manual was right after all):
2508 opcode for sysctl is 0x659
2510 Mon Oct 23 12:03:04 PDT 1989
2511 Use G960BASE and G960BIN environment variables to find 'sx' utility.
2513 Mon Oct 16 14:15:09 PDT 1989
2514 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
2516 Mon Oct 2 15:56:31 PDT 1989
2518 Added 960CA disassembly support.
2520 To simplify maintenance:
2521 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
2523 - eliminated opcode.h: incorporates tables into i960-pinsn.c
2524 - moved 960-specific routines from i960-pinsn.c to i960-md.c
2525 - made disassembly interface identical to that in gdmp960.
2529 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
2531 * target.h: Allow targets to stack. Add target_has_memory,
2532 _registers, etc. Restructure memory access and "info files"
2533 to walk the target stack.
2534 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
2535 target.c: Change tables to match target.h.
2536 * inflow.c (child_mourn_inferior): pop child_ops.
2537 (generic_mourn_inferior): Use new has_stack flag.
2538 * infptrace.c (child_xfer_memory): New memory regime.
2539 * inftarg.c (child_files_info): New "info files" regime.
2540 * remote-eb.c: New memory regime, new info files.
2541 * remote-vx.c: New memory regime, new info files. Now use
2542 separate targets for VxWorks attachment to machine, and
2543 actually running a process under VxWorks, since one has
2544 stack & execution & regs and the other doesn't.
2545 * remote.c: New memory regime, new info files.
2546 * sparc-xdep.c (fetch_core-registers): New memory regime.
2547 * target.c: New routines and support for stacked targets,
2548 new memory regime, new info files regime.
2551 Generalize section handling for an arbitrary number of sections,
2552 including use of the new BFD (binary file) library.
2553 * gdbcore.h: Add struct section_table.
2554 * exec.c (build_section_table): Iterate all sections and
2555 record what gdb needs to know about them.
2556 (exec_command): Use it.
2557 (exec_xfer_memory): Use the table.
2558 (exec_files_info): Print the table.
2559 * core.c (core_file_command, core_xfer_memory, core_files_info):
2561 * source.c (find_source_lines): Use bfd_get_mtime.
2562 * dbxread.c: Quick changes to make it compile with new BFD.
2563 * utils.c (error): Avoid using bfd_error in generic routines.
2565 * core.c (core_fetch_registers): Get from the ".regs" section of
2567 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
2569 * inferior.h (attach_flag): Export.
2570 * infcmd.c (run_command): use new target_create_inferior.
2571 * infrun.c (child_create_inferior): Don't return result.
2572 * Makefile.dist (VERSION): 3.91.4.
2574 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
2576 * breakpoint.c (bpstat_num): Handle breakpoints which have
2577 since been deleted, such as temporary breakpoints.
2578 infcmd.c (program_info): ditto.
2580 * core.c (core_file_command): Display the frame where the core
2585 * remote-vx.c (target_command): Merge in target command from
2586 targ-vx.c. A few other cleanups.
2588 * TODO, Projects: Lots more stuff to do...
2590 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
2592 Massive changes to wall off the remote-debugging interface
2593 behind a function vector. The port to handle VxWorks targets
2594 is also part of this.
2596 All files: Replace references to renamed functions,
2597 remove references to remote_debugging, remove references to
2598 have_include_file, have_core_file in favor of target_has_stack,
2599 target_has_memory, etc.
2601 * Modularize the breakpoint interface.
2602 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
2603 a breakpoint instruction.
2604 breakpoint.c: struct breakpoint's shadow_contents now sized as
2606 (insert_breakpoints): Vector to target to install breakpoints.
2607 (remove_breakpoints): Vector to target here too.
2608 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
2609 sparc-tdep.c (single_step): Use new breakpoint interface for
2610 the single-step breakpoints.
2611 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
2612 New file, contains routines to insert and remove breakpoints by
2613 reading out the old contents and later replacing them. This is
2614 how ptrace breakpoints work, and many remote systems as well.
2616 * tm-vxworks68.h: New config file, overrides a few things for
2617 Wind River's preferences.
2619 * target.h: New file, for transfer vector used to talk to the
2620 inferior (child, attached, core, exec, remote, etc). All accesses
2621 to the thing being debugged should come through these vectors.
2622 target.c: New file, routines to handle transfer vector.
2623 (various files): Add transfer vectors XXX_ops for the various
2624 targets and pseudo-targets (core files, etc) we support.
2626 * breakpoint.c (bpstat_stop_status): Further explorations of
2627 watchpoints and why things don't work all the time.
2628 (bpstat_alloc): New fn to allocate a bpstat and chain it.
2630 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
2631 the local gdbinit if it doesn't already have it.
2633 * core.c (core_ops): add and install.
2634 Allow core debugging without exec file.
2636 * dbxread.c (free_and_init_header_files): Merge two fns.
2637 (end_symtab): Free named symbol table when a new version comes in.
2638 (read_dbx_symtab): Relocate all kinds of symbols with base
2639 address. First step toward handling different text, data, bss
2641 (add_file_addr_command): Renamed add_file_command.
2642 (add_file_command): Vector to remote handler.
2643 Add "load" as an alias for "add-file" command.
2645 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
2646 non-returning functions.
2648 * exec.c: Add exec_ops, and push it as a target when an exec
2651 * infcmd.c (run_command): Pass executable file name and arg list
2652 separately when starting an inferior. Permit "run" when no exec
2653 file is specified, for VxWorks.
2654 (detach_command): Move to child_detach in inftarg.c.
2656 * inftarg.c: New file. Unix-child-specific routines, and the
2657 child_ops structure.
2659 * inferior.h (registers): Export "registers" as the way for
2660 target dependent register handlers to find gdb's local copy of
2661 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
2662 since it is now used by places that want wait_for_inferior to
2663 handle the grunge but want to see every trap from the inferior.
2665 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
2666 Eliminate remote_debugging hooks in terminal handling.
2668 * infrun.c: Replace start_inferior with child_create_inferior.
2669 Move all the hair of Unix shells and ptrace idiosyncracies into
2670 child_create_inferior, so remote handlers don't have to deal.
2671 Remove running_in_shell. Rename stop_after_attach to
2672 stop_soon_quietly, and use it in a few other places where we want
2673 to just call wait_for_inferior and get control back on the first
2674 trap. trap_expected now never takes a value > 1.
2675 (init_wait_for_inferior): Initialize static vars when a new
2678 main.c (gdbinit): Add new hook for .gdbinit file name, let
2679 it be overridden by config files as GDBINIT_FILENAME.
2680 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
2681 Both of these are used for VxWorks gdb.
2683 mcheck.c: rename include file "gmalloc.c" to avoid problems
2684 with system include file "malloc.c".
2686 param-no-tm.h: New include file, same as param.h but does not
2687 include the default "tm.h" file. This is used in files where
2688 the target is known, e.g. remote-eb.c or sparc-xdep.c.
2690 param.h: Now just a shell that includes tm.h and param-no-tm.h.
2692 remote-vx.c: New file, VxWorks remote debugging support. Uses
2693 RPC routines that are shared with the target system, in directory
2696 remote.c: Vectorize remote interface.
2698 source.c: Globalize source_path, and make an alias "l" for "list"
2699 since we now have the "load" command.
2701 sparc-xdep.c: Use new param-no-tm.h.
2703 symmisc.c (free_named_symtab): Add new function from Wind River.
2704 However, ifdef it out for now while we think about what it should
2707 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
2709 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
2710 non-Unix-children handle this with their own code in the target
2713 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
2714 source and target lists. Add vx-share to default list of include
2715 directories. Add new files to src and target lists: mem-break,
2716 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
2717 ${srcdir} versions of munch and createtags are used.
2719 * valops.c (find_function_addr): Split out of call_function.
2720 (call_function_by_hand): Rename call_function; this function
2721 calls functions in the target by laboriously patching the target
2722 word-by-word with the right stack, args, regs, etc.
2725 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
2727 Handle AMD 29000 a bit better.
2729 * remote-eb.c (readchar): Mask received char log to make it readable.
2730 (remote_start): Pass arguments down to executing program.
2731 Make startaddr unsigned.
2732 infrun.c (start_inferior): Accept args, pass them to
2734 infcmd.c (run_command): Pass args down to start_inferior.
2736 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
2737 the target object file format.
2738 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
2740 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
2741 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
2743 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
2745 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
2746 * TODO: We did a few things, we have more to do though.
2748 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
2749 * inflow.c (inferior_died): Clear deferred stores.
2751 * Debug problems with dummy frames and calls to the inferior.
2752 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
2753 * sparc-tdep.c (do_restore_insn): Simplify.
2754 (sparc_frame_find_saved_regs): Simplify and fix what we find.
2755 (sparc_push_dummy_frame): Simplify and fix what we push.
2756 (sparc_pop_frame): Slightly more hair here, deciding whether
2757 we are restoring a saved PC or returning to a return address in %i7.
2758 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
2760 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
2761 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
2762 * obstack.h (chunkfun): ditto.
2763 * defs.h (xmalloc, xrealloc): ditto
2765 * utils.c (quit): Grab the terminal from the child if necessary.
2767 * inflow.c (term_status_command): Rename to term_info, change
2770 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
2771 (is_delayed_branch): Speed up.
2772 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
2773 Still missing some float ops, and needs testing.
2775 * Support for input and output radixes other than base 10
2776 * defs.h (input_radix, output_radix): Declare.
2777 * expread.y (yyparse, parse_number): Handle changes of input
2778 radix, and ambiguous names-or-numbers in radixes >10.
2779 * printcmd.c (print_scalar_formatted): Print formatted hex
2780 numbers in varying column widths.
2781 * valprint.c (val_print): Use output_format to print scalar ints.
2782 (set_input_radix, set_output_radix, set_radix): Create.
2783 (set_output_radix): Set output_format from output_radix.
2784 (_initialize_valprint): add `set radix' but leave the others off.
2786 * main.c (execute_command): Let stupid questions be turned off.
2787 (_initialize_main): Handle "set stupidity", etc.
2789 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
2790 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
2792 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
2794 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
2795 bfd stuff is still screwed up, but with some manual work, it
2798 * breakpoint.c (bpstat_do_actions): Start over if a command
2799 proceeds the inferior, since the inferior will have stopped and
2800 will need to have its new stop-actions taken care of.
2802 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
2803 compiler fits, simplify it.
2805 * gdb.texinfo (directory command): Doc new dir command.
2806 source.c (directory_command): "dir" now puts things on the front
2807 of the path, moves dups up front, and handles multiple names
2808 on the command line, inserting each one in order. It also
2809 blows away cached line and full_filename info.
2811 * stack.c (backtrace_command): Skip "more stack frames follow"
2814 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
2815 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
2816 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
2817 The only odd one was Gould NP1, which had defined vprintf to
2820 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
2821 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
2822 variable, inspect_it.
2823 valprint.c (print_string, val_print): Use the global inspect_it
2824 to indicate whether to print in Epoch style or normal style.
2826 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
2828 * printcmd.c (call_command): add an alias for the "print" command
2829 which runs expressions and doesn't print the result if void.
2830 (print_command_1): implement it.
2832 * command.c: Remove #if 0'd code. Initialize all the fields
2833 in add_cmd (). Rename do_nothing_command to
2834 not_just_help_class_command, and make it externally visible.
2835 command.h: add user_commands to struct.
2836 * main.c (define_command): Don't overload c->function with a char
2837 string as well as a function pointer.
2839 * eval.c (evaluate_subexp): Reinstall tiemann changes to
2840 calling convention of value_struct_elt () that got dropped in
2843 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
2844 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
2846 * tm-sparc.h (POP_FRAME): replace some constants with defines.
2848 * sparc-xdep.c (store_inferior_registers): defer stores to regs
2849 until a good time (e.g. when we are about to run the child),
2850 saving ptrace calls.
2851 * infrun.c (proceed): handle DO_DEFERRED_STORES.
2852 * tm-sparc.h: define DO_DEFERRED_STORES.
2854 * sparc-xdep.c (store_inferior_registers): when storing float
2855 registers, don't store stack regs too. When storing the SP,
2856 however, DO store the stack regs too. This fixes a bug in which
2857 the dummy frame is not recognized when a call_function finishes,
2858 because its frame pointer (in the stack regs) was never
2860 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
2861 even though we don't know how to read them from an inferior.
2862 valops.c (call_function): Comment about storing SP.
2864 * infrun.c (save_inferior_status): Save away the original bpstat
2865 chain so it can be restored later. Install the copied version for
2866 use by whoever saved the status. It will be blow away by
2867 restore_inferior_status, and the original chain restored. This is
2868 important for people who have pointers into the original.
2870 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
2871 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
2872 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
2875 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
2877 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
2878 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
2879 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
2881 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
2883 * Merge Mike Tiemann's multiple inheritance changes from Sun.
2884 Store the baseclasses in a type struct starting from array element
2885 0 rather than from the unusual array element 1.
2887 dbxread.c: the above.
2888 (virtual_context): Add
2889 Read new debug information about which virtual function table
2890 a virtual function is from, and store it in fn_field.fcontext.
2892 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
2893 TYPE_FN_FIELD_STATIC_P.
2895 symtab.c: the above.
2896 valops.c: the above. Handle pointer casts of object *'s.
2897 (search_struct_method): Add.
2898 (value_struct_elt): First arg is now a pointer to a value, and is
2901 valprint.c: the above.
2902 values.c (value_virtual_fn_field): Add type arg. Handle
2903 offsetting to the proper object when calling virtual fns.
2905 (baseclass_addr): Add valuep arg.
2907 * README: Document the current state of BFD config (missing).
2908 * TODO, ChangeLog, Makefile.dist: Roll version.
2909 * WHATS.NEW: Add summary of changes since 3.5.
2911 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
2913 * dbxread.c (read_struct_type): Clear bit vectors whenever
2915 symtab.c (B_CLRALL): define.
2917 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
2918 using == rather than =. Huh... This fixes the dreaded problem
2919 wherein builtin_type_int becomes TYPE_CODE_FLT.
2921 * core.c (info_files): Show the inferior pid.
2923 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
2924 already knows how to look in the source directory.
2926 * Remove psymtab hair from many places. Remove duplicated code
2927 for searching symbol tables. Hide psymtabs from most places.
2928 Make it fast to get from a psymtab to its symtab.
2930 blockframe.c (blockvector_for_pc): Remove psymtab hair.
2931 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
2932 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
2933 dbxread.c: export psymtab_to_symtab, make it work if called N times.
2934 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
2935 new symtab completely. New psymtabs get symtab pointer
2936 initialized to zero. Remove MI warning printf.
2937 symtab.h: Comments. Add psymtab to symtab pointer.
2938 (PSYMTAB_TO_SYMTAB): New macro.
2939 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
2940 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
2942 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
2944 (print_frame_info): Avoid special-casing symbols that have not yet
2947 * source.c (open_source_file): Quick path if we have already
2948 located the source file by its full name.
2950 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
2951 find_pc_psymtab. When a name is found in the misc function
2952 vector, search the symbol table for its mangled name, not the
2953 name that the user typed.
2955 * bfd.h: Fix missing comment terminators, make #endifs match.
2957 * valarith.c (value_less): Handle unsigned int comparisons.
2958 Add FIXME about pointer compares, which assume host and target
2959 pointers are the same.
2961 * command.c (do_nothing_command): lint
2962 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
2963 fix comments on debug symbol format for visibility. Actually set
2964 visibility of symbols.
2965 main.c (echo_command): lint; use <readline/history.h>.
2966 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
2967 obstack.h (_obstack_blank): Rearrange pointer math to avoid
2968 pointing past end of allocated memory; saber complains.
2969 obstack.h: Declare the external functions that we use.
2970 valarith.h: use <string.h>
2971 solib.c (solib_add): lint.
2973 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
2975 * main.c (initialize_main): Default info_verbose to off, now that
2976 symbol reading is fast.
2977 (quit_command): Avoid clobbering exec_bfd while quitting.
2979 * Initial BFD (binary file diddling library) merger:
2980 coffread.c: Change AOUTHDR to struct exe_hdr.
2982 core.c: initialize initialized data at compile time.
2983 (core_file_command): Move from coredep.c, convert to bfd.
2984 (xfer_core_file): Convert to bfd.
2985 exec.c (exec_file_command): use bfd routines.
2987 mips-tdep.c: Remove exec_file_command and friends.
2990 * coredep.c: (fetch_core_registers) Convert core_file_command to
2991 fetch_core_registers.
2992 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
2994 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
2995 (my_bfd_read): More bogosity, which I don't think we call.
2996 (program_name): Remove this atrocity asap!
2998 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
3001 values.c: allocate_repeat_value was not clearing the
3002 optimized_out field.
3003 (value_static_field): minor stylistic fix (wrong macro was used).
3004 valops.c (value_struct_elt_for_address): didn't work for C++
3007 * signame.c (_initialize_signame): Initialize signal names once.
3009 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
3010 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
3011 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
3013 * remote-eb.c: Support user-settable baud rates on the serial port.
3015 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
3017 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
3019 * tconfig/sun3os4: Remove warning about native assembler,
3020 since it also occurs in the xconfig file.
3022 * findvar.c (registers): Allocate some slop after `registers'
3023 to prevent stray accesses from trashing the next variable.
3025 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
3026 on the sun-3, by changing the #ifdef from `sun3' (which is not
3027 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
3028 vars, which happened to follow `registers' in the executable.
3030 * readline/history.c (history_search): Heed gcc-2's advice
3031 and parenthesize && inside ||).
3033 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
3034 tm-29k.c: Insert FSF copyright headers.
3036 * remote-eb.c: Better comments.
3038 * Makefile.dist: Update to 3.91.6.
3039 * TODO: note PREPARE_TO_STORE problem.
3041 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
3043 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
3045 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
3047 * infrun.c (wait_for_inferior, at end): Don't set up
3048 prev_* if the inferior no longer exists.
3050 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
3051 CANNOT_EXECUTE_STACK.
3052 valops.c (call_function): Use it.
3054 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
3056 * inferior.h (PC_IN_CALL_DUMMY): New macro.
3057 infrun.c (wait_for_inferior, 2 places): Use it.
3059 * values.c (value_being_returned): Only use
3060 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
3062 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
3063 right thing for remote-eb.c.
3065 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
3066 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
3068 * blockframe.c: Put get_frame_saved_regs inside #if !defined
3069 (FRAME_FIND_SAVED_REGS).
3071 * findvar.c ({fetch,store}_registers): Check for
3072 REMOTE_{FETCH_STORE}_REGISTER macro.
3074 * findvar.c (get_saved_register): Add argument lval and
3075 change meaning of argument addr.
3076 findvar.c: Change calls to get_saved_register to reflect
3077 new calling convention.
3078 valops.c (value_assign): Use get_saved_register instead of
3079 find_saved_register.
3081 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
3083 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
3084 an (uninitialized) pointer to one. Use "&" when passing it
3087 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
3089 * coffread.c (getfilename): Use DGUX x_offset and x_name if
3092 * coffread.c (symbol_file_command): Put semicolon after
3094 Put safe_to_init_tdesc_context in #if defined (TDESC).
3095 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
3096 coffread.c: #include <sys/stat.h>.
3097 (read_coff_symtab): Typo: in_source_files -> in_source_file.
3098 Add missing ')' in check for "lc%" and friends. Remove
3100 Declare read_one_sym() at top of file.
3101 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
3102 MC68WRMAGIC can have the same value without causing a duplicate
3105 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
3107 * Allow a Makefile to be built without building the
3108 tm and xm file links that screw up builds in subdirectories.
3109 This is done with `config.gdb none', then you can do things
3110 like `make gdb.tar.Z'.
3111 * tconfig/none: Config file for no target system
3112 * xconfig/none: Config file for no host system
3113 * config.gdb: If no TM or XM files are called out by the
3114 host or target file, don't make links for them.
3116 * cplus-dem.c: Add documentation.
3118 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
3119 simple error, so the user's gdb doesn't crash due to some object
3120 file problem (e.g. somebody is rebuilding the file out from under
3123 * printcmd.c (print_address_symbolic): demangle the symbol.
3125 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
3126 Motorola copyrights in it. Make "make gdb.tar.Z" work.
3127 (alldeps.mak): sort and uniq all results from this; duplicates
3128 hose gdb.tar.Z link building. Remove RCS files from
3129 tconfig and xconfig. Add config files for sun386. Add
3130 a few odd files to OTHERS and HFILES.
3132 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
3134 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
3135 Roll version number to 3.91.5. Make lint work in bindir.
3137 * README: Document cross-debugging and new file structure.
3139 * blockframe.c: Lint. Include "value.h" to declare read_register.
3140 (find_pc_partial_function): remove duplicate line.
3142 * command.h: Lint. Declare error_no_arg and dont_repeat.
3144 * tm-news.h: Remove inadvertently duplicated stuff.
3146 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
3147 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
3149 * config.gdb: Allow `config.gdb host target' form. Clean
3150 up previous change that printed bogus messages when you just said
3153 * core.c: #include "command.h" for lint.
3156 * main.c: Remove some casts of enums. Lint.
3163 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
3165 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
3166 read it from memory. This will allow us to save ptrace calls
3167 eventually. Changed caller single_step too.
3169 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
3170 that we aren't going to use, saving many ptrace calls, especially
3171 when watchpointing or single stepping. Use some #define's for
3173 (store_inferior_registers): Ditto.
3174 (core_file_command): Use some #define's for constants.
3176 * tm-sparc.h: Add #define's for some register numbers, so we
3177 can eliminate the use of random constants in sparc-xdep.c.
3179 * stack.c (frame_command, print_frame_info, up_command,
3180 down_command) Remove frame_changed, since it
3181 causes a bug and doesn't seem to do anything useful. In some
3182 places it was used as a flag, in others as a stack level (?).
3184 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
3185 default is to use the portable (vprintf) version rather than the
3187 * xm-news.h (MISSING_VPRINTF): Add.
3189 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
3191 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
3193 * Remove stuff that forces -Bstatic linking of gdb, and warnings
3194 about linking debugged programs -Bstatic in the sun?os4 config
3195 files in tconfig and xconfig subdirectories.
3197 * main.c (main): Remove unreached exit(0) now that we exit
3200 * Create TODO file for online bug list. There are too many
3201 "little" bugs to keep track of on paper.
3203 * Change Projects file to refer to bug-gdb@cygnus.com
3204 rather than kingdon@ai.
3206 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
3208 * Makefile.dist (VERSION): 3.91.4 now.
3210 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
3211 (condense_misc_bunches): Add sanity check that misc_count is
3212 the same as the number of symbols in the bunch.
3214 * coffread.c: rename init_misc_bunches. Pass an argument
3215 to condense_misc_bunches (a zero).
3217 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
3218 every time we are called; don't rely on our caller to do it.
3219 (add_file): Remove call to init_misc_bunches.
3221 * mipsread.c: Only warn, don't error, if unknown symbol types.
3222 This keeps an old gdb from falling on its face if it sees newly
3223 extended symbol info. Rename init_misc_bunches.
3225 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
3227 * Merge in changes from Per Bothner for DECstations and other
3228 MIPS stuff. The rest is Bothner speaking:
3230 The next message is a merger of Alessando Forin's mips port with
3231 mine. I've tried to use my good if biased judgment to get
3232 the best of both. It *does* need testing.
3234 Some of the changes are general, *not* mips-specific.
3237 Didn't believe in little-endian bit order.
3238 There are still inconsistencies about whether flags
3239 like BITS_BIG_ENDIAN are integer (#if ...) or
3240 boolean (#ifdef ...). I tried to paper over them.
3242 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
3243 Moved some misc_function code that was common to
3244 {dbx,coff,mips}read.c to symtab.c.
3245 In the process, I think I cleaned things up a bit.
3246 At the same time, moved obsavestring and obconcat to symtab.c.
3249 Removed obsolete condense_addl_misc_bunches (use
3250 condense_misc_bunches(1) instead).
3253 Needed to include <sys/dir>, at least on DECstations.
3255 valops.c, mips-tdep.c, tm-mips.h:
3256 Added PUSH_ARGUMENTS macro to support funny argument-pushing
3257 conventions (when STACK_ALIGN is insufficient).
3258 Needed on mips, where doubles need 8-byte alignment,
3259 but ints only need 4.
3262 Removed cruft that was not being used.
3263 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
3266 Print $ before register-names (I think that makes things a little
3268 Never print two instructions, even if one delays.
3269 Removed hex-disassemble set_cmd. (This is not mips-specific,
3270 so I think the argument is whether it is generally worthwhile or not.
3271 I'm inclined to think not, given how easy it is to
3272 convert between radixes in gdb.)
3275 This is basically Alessando's code.
3276 It doesn't use obstacks; I changed it to use obstacks
3277 in a few minor places where using malloc causes a
3278 memory leak. (Probably, more places could/should be changed.)
3279 I added record_misc_function where it was missing.
3280 In symbol_file_command and add_file_command, I tried
3281 to make the code consistent with more recent versions.
3282 Minor sylistic changes in parse_procedure.
3283 Make a .gdbinfo. psuedo-symbol point back to the real
3284 procedure symbol (using the isym field).
3287 This is basically from my port, but with a lot of details
3288 and a number of routines merged in from Alessando's version.
3289 I basically used my code "raw" backtrace (use heuristics
3290 from the actual code, rather than symbol table info) - though
3291 the idea is Alessandro's. I feel my code is a little cleaner
3292 here, particularly in being a little more flexible, such as being
3293 able to handle gcc-produced code (which it now can).
3294 It also doesn't do frame caching (which is not useful
3295 more recent gdb versions).
3296 I also used my code for push_/pop_dummy, more or less.
3297 I tried to incorporate AF's code for testing sigtramp
3298 while backtracing; I probably got it wrong.
3299 Added mips_print_register, which tries to scrunch as much
3300 information as possible on a screen...
3301 Removed the skip-prologue set_cmd. As with hex-disassemble (see
3302 under mips-pinsn.c), I don't see anything mips-specific here,
3303 and I don't see it being all that useful anyway.
3306 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
3307 Use more register names (rather than hard-cases numbers).
3309 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
3311 * Hack up 3.90.11 changes:
3313 * Makefile.dist (depend): parameterize $(GCC).
3314 Add solib.c and solib.o.
3315 (readline): Fix vpath for both absolute or relative SRCDIR.
3317 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
3318 Also, let the part I didn't understand at least compile so
3319 I can test the rest. FIXME.
3321 * dbxread.c: Fix thinko using strcmp.
3322 (init_psymbol_list): declare static.
3323 (partial_symbol_file_open): Comment cleanups better, avoid
3324 cleaning up the string table since the caller will do that.
3325 Move the stat for mod time into symbol_file_command, temporarily.
3326 (There should be a mod time for each symbol file, eventually,
3327 to control its rereading. FIXME.)
3329 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
3330 SunOS, which gives error for shared libs otherwise. (From
3331 Schaefer, probably FIXME needs work for portability.)
3333 * solib.c: Move #include "param.h" to work.
3334 Lowercase all the Uppercase Letters In the Messages.
3335 (find_solib): Clean up inferior_so_name for debug printouts.
3336 Allow no argument, to mean all shared libraries.
3338 * symmisc.c: include param.h to get CLEAR_SOLIB.
3340 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
3342 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
3343 to 3.90.11. ChangeLog entries below are from this.
3345 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
3349 * Makefile.dist (HFILES): Add tm-sunos.h.
3351 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3355 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
3357 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
3359 * sparc-opcode.h Added single-operand version of rett.
3361 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3363 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
3364 Put parens around gcc_p in expansion.
3366 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
3368 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
3370 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3372 * Changes for Sun shared libraries:
3373 blockframe.c (find_pc_partial_function): If a non-text symbol
3374 is found, set *address = pc - FUNCTION_START_OFFSET.
3375 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
3376 Disable breakpoints instead of giving an error.
3377 source.c (select_source_symtab): Initialize cs_pst.
3378 symmisc.c: Call CLEAR_SOLIB if defined.
3379 symtab.h: Make text{low,high} CORE_ADDR not int.
3380 (psymtab): New field addr.
3382 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
3383 (record_misc_function): Give correct type for N_DATA symbols.
3384 (condense_misc_bunches): do "misc_function_count = j" regardless
3386 Take code which is shared between symbol_file_command and
3387 add_file_command and put it into partial_symbol_file_{open,read}.
3388 Split add_file_command into add_file_command and add_file.
3389 Make psymtab_to_symtab read in the string table if the file
3391 Two new parameters to read_dbx_symtab and start_psymtab.
3392 tm-sunos.h: New file.
3394 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3396 * infcmd.c: Change cont_command to continue_command and "cont"
3399 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3401 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
3403 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
3405 * values.c (USE_STRUCT_CONVENTION): Check for structures of
3406 size 1,2,4,8 rather than size < 8.
3408 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
3409 as necessary, not just once.
3411 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
3413 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3415 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
3417 * tm-news.h: Add CALL_DUMMY_*.
3419 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
3421 * config.gdb: In list_host, list_target, use ${i}, not $i.
3423 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3425 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
3427 * sparc-opcode.h: Change all store floating-point state register
3428 instructions to have the right match & lose fields.
3430 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3432 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
3434 config.gdb: If srcdir != ., create readline directory and
3435 copy a makefile into it.
3437 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
3438 consistency with POSIX.
3440 * breakpoint.c (bpstat_stop_status): Disable watchpoint
3441 when we exit its exp_valid_block.
3443 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
3445 * Makefile.dist: Bump version to 3.91.3.
3447 * Clean up handling of breakpoint commands (somewhat).
3448 Prompted by Tiemann bug report "cont 10" doesn't work any more.
3450 inferior.h: Add breakpoint_proceeded to inferior status struct
3451 and globals; save it and restore it.
3452 (clear_breakpoint_commands): Cleanup, remove old #define.
3454 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
3455 (save_inferior_status, restore_inferior_status): handle it also.
3456 (proceed): Remove earlier code that set breakpoint_proceeded.
3457 It is now set only in clear_proceed_status.
3458 (clear_proceed_status): Cleanup, use bpstat_clear rather
3459 than clear_breakpoint_commands. No callers need the stop_bpstat
3460 between clear_proceed_status and proceed.
3462 infcmd.c: Add breakpoint_proceeded definition and comment.
3463 (cont_command, jump_command, signal_command): Move call to
3464 clear_proceed_status right next to call to proceed.
3466 breakpoint.c (bpstat_do_actions): Avoid clobbering our
3467 caller's argument while running down the chain of breakpoints.
3468 Use new variable "breakpoint_proceeded" to determine when
3469 a command that it executes moves the inferior past the
3471 (bpstat_clear): Handle NULL argument.
3472 (bpstat_clear_actions): Avoid useless call to
3473 breakpoint_auto_delete.
3474 (delete_breakpoint): Clean up bpstat's that are pointing to
3475 the deleted breakpoint from the stop_bpstat chain.
3476 (breakpoint_auto_delete): Simplify.
3478 * Clean up handling of EOF, error on stdin, etc. This was
3479 prompted by a network problem that caused gdb to go into an
3480 infinite loop filling up its malloc'd memory.
3482 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
3483 not clear_breakpoints_commands, which is now gone.
3484 (main): If command_loop returns (e.g. from EOF on stdin), do
3485 a quit_command (looping back to command_loop if quit_command
3486 doesn't really quit).
3487 (command_loop): check result from command_line_input and
3488 exit if it returns NULL, rather than passing the NULL to
3490 (gdb_readline): Free malloc'd result space before returning
3493 * utils.c (query): Handle C-d to mean "yes", just as if the
3494 input was not a terminal. Also avoid infinite loop if EOF
3495 occurs in mid-input-line before newline. This allows
3496 query to be used at EOF on stdin with reasonable results.
3498 * infrun.c (proceed): Set breakpoint_proceeded.
3500 * values.c (value_as_long): Avoid infinite recursion for enums.
3501 (_initialize_values): Fix typo in help msg (kingdon).
3503 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
3504 RL_LIB for linking. This allows -lreadline for linking
3505 and nothing for dependencies, once readline is a real library.
3507 * config.gdb: Jim Kingdon: give useful error message if the
3508 host or target type is not recognized.
3510 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
3511 it just defines it. Dumb, but deal with it.
3513 * Jim Kingdon suggests:
3514 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
3516 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
3518 * Makefile.dist (VERSION): Bump version # to 3.91.2.
3520 * Clean up Bothner's changes.
3522 * blockframe.c (clear_pc_function_cache): New function.
3523 * blockframe.c: remake cache_pc_function_* static.
3524 * dbxread.c (symbol_file_command): remove references to
3525 cache_pc_function_* variables.
3526 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
3527 * printcmd.c: Avoid kludging a global variable (addressprint)
3528 to avoid printing the address of a string twice. Instead,
3529 pass the format letter 's' down low enough that it can be seen
3530 to avoid this problem.
3531 (print_formatted): Pass format arg to value_print.
3532 (restore_addressprint): Remove function.
3533 (do_examine): Avoid hacking addressprint, cleanups and such.
3534 (print_frame_args): Add a comment to a Bothner change.
3535 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
3536 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
3537 to wipe out the values cached in blockframe.c.
3538 * symtab.c (find_method): Add comment saying how big you must
3539 allocate to be "big enough". Per being terse again.
3540 * valprint.c (val_print): Handle format letter "s" to print
3541 strings without addresses. Add comment to vtbl printing code
3542 which casts with wild abandon. Rearrange reference-printing
3544 @0xaddr: value (print w/addressprint)
3545 value (print w/~addressprint)
3546 @0xaddr (parameter lists w/addressprint)
3547 or nothing (parameter lists w/o addressprint)
3549 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
3551 * Merge more changes from Per Bothner:
3553 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
3554 annoying) that I tried to improve it. Here are my suggestions.
3556 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
3559 Do automatic de-reference when taking the address of a reference.
3561 Don't deref_ref when printing parameter lists.
3563 More attempts at treating refernences properly.
3565 In val_print, if deref_ref==0, don't print dangling " = ".
3567 Add COERCE_REF macro, which de-references an REF.
3569 * Merge changes from Per Bothner:
3571 * Fixed (Sony news)-specific configuration problems.
3572 * Fixed other problems with using vanilla pcc and libc (enum problems;
3573 assumption that vsprintf exists).
3574 * Some major speed-ups (finc_pc_partial_function now caches a match;
3575 parsing avoids duplicate symbol_lookup calls).
3576 * Changed handling of baseclasses (no longer use baseclasses field
3577 of struct type, use the first n_baseclasses fields instead).
3578 * Various minor changes/fixes, most C++-related.
3581 Cache the most previous match from find_pc_partial_function.
3582 (Save both low and high ends of matching function's pc range.)
3583 This speeds up the loop of infrun.c:wait_for_inferior quite
3584 a bit, and makes step/next commands much zippier.
3586 Added an enum->int cast (otherwise, some compilers barf).
3588 No longer set baseclass offset to 0, since multiple
3589 inheritance now mostly works.
3590 Added a number of casts, to shut up compiler warnings
3591 (after stabs where made enums, not ints).
3592 When discarding a symbol table (in symbol_file_command),
3593 must clear the cache introduced in blockframe.c.
3594 Don't convert $vtbl_ptr_type to vtbl any more.
3595 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
3596 Mask off sign bit emitted by g++ for virtual table offset.
3597 Set voffset to -1 (not 1) for static member functions.
3599 Changed parsing/lexing of names to avoid doing symbol lookup twice
3600 (once when lexing to determine symbol class, once for real).
3601 Now only call symbol_lookup once. Fields of 'this' win especially big.
3603 Subpress printing addr twice in the case of 'x/s addr'.
3605 lookup_basetype_type is no longer used.
3606 Add find_methods as recursive helper function to decode_line_1.
3607 This allows multiple inheritance to work.
3608 Also, once one or more matches has been found, do not look in
3609 base-classes. (Baseclass methods would be overridden, anyway.)
3611 Removed baseclasses array in struct type.
3612 Instead of using baseclasses[i], use fields[i-1].
3613 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
3614 Changed sign convention of voffset (previous was inconsistent).
3616 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
3618 Used to assume existence of vsprintf. Re-written to not need it
3619 if HAVE_VPRINTF is undefined.
3621 typecmp was too pessimistic. Made it less so.
3623 Don't print space after address.
3624 If vtable points to a misc symbol (with 0 offset), print it,
3625 since that indicates the actual class of the object.
3626 Changed ype_print_derivation_info to use new inheritance
3627 scheme (without baseclasses vector).
3629 In value_primitive_field, fixed some bugs left over from previous set of fixes.
3630 Also, changes needed because TYPE_BASECLASSES were removed.
3632 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
3634 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
3637 If there is no path set, and the symbols don't indicate what directory
3638 a file was compiled in, look in the current directory. But either
3639 a path or a known compilation directory will prevent this.
3642 Three independent bug fixes:
3643 * Remove the #if 0 block that breaks some stuff.
3644 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
3645 adapt gdb to either SunOS 4.0.* or 4.1.
3646 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
3649 Instantiate the class T when looking for methods in it. (Tiemann@sun)
3652 (type_print) Demangle the name being printed.
3653 (type_print_base) Handle botched demangling without coredump (tiemann).
3656 (check_stub_method): Document routine.
3657 (tiemann) fix bug for no-arg functions
3658 Avoid clobbering beyond end of malloc'd storage.
3659 Terminate the argument list properly.
3661 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
3663 * Changes merged by John Gilmore:
3666 In breakpoint_1, use new print_address_symbolic instead
3667 of find_pc_partial_function. (This forces use of assembler-level
3668 addresses, and avoids misleading non-mangled source-level names.)
3670 Generalize ansi argument such that -1 means skip arglist totally.
3671 Removed global variable print_ansi_qualifiers (which made
3672 code non-reentrant), in favor of extra explicit arguments
3673 to internal routines.
3675 Add new helper function print_address_symbolic.
3676 Use find_pc_misc_function instead of find_pc_partial_function
3677 (since we want assembler-level symbols here).
3679 Print unknown function as just "f (...)", not "f (...) (...)".
3680 Use new fputs_demangled explicitly.
3682 Fixed a typing violation (problem: value.h cannot be imported
3683 without renaming many variable in this file).
3684 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
3685 decode_line_1: Moved forward some never-reached code.
3686 Made decode_line_2 skip function prologues correctly.
3688 fputs_filtered should not demangle by default.
3689 Add new fputs_demangled to demangle on demand..
3691 Change value_struct_elt to use value_primitive_field (using recursive
3692 utility function search_struct_field). This allows foo.bar to work
3693 for multiple inheritance (so far only for data fields).
3694 Change check_field in the same way (recursive helper function
3695 to support multiple inheritance).
3696 (Note: there are more of these problems that I haven't fixed.
3697 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
3698 value_of_this: 'this' symbol name is now just "this", note "$this".
3700 Don't print static members.
3701 Avoid printing "members of <type>" if there are none.
3702 Simplified type_print_derivation_info by merging duplicate code.
3703 Remove useless blank lines in type_print_base (ptype command).
3705 Added declaration of new routine value_primitive_field.
3707 Added value_primitive_field which is generalized version of
3708 value_field that can handle multiple inheritance (non-zero offsets etc).
3709 Re-implemented value_field to call value_primitive_field.
3711 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
3713 * infcmd.c -- insert else to avoid 'delete env' coredump when you
3714 delete the whole environment. Karl Berry reported the bug.
3715 * source.c - fix openp to avoid //'s in filenames, which
3716 trigger an Emacs bug causing it to not be able to find files
3717 when running gdb in a window.
3718 * dbxread.c - zap the #if 0 that botches the add-file code.
3719 It seems to work a lot better without all the code commented out.
3721 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
3723 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
3726 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
3728 * Makefile - added a ${CFLAGS} to a couple of entries,
3729 added remote-sa.sparc.c
3730 * added remote.sa-sparc.c, a modification of remote.c
3731 which conducts a dialog directly with the SparcStation prom.
3732 * breakpoint.c, infrun.c, sparcdep.c added
3733 remote_insert_breakpoint(), and remote_remove_breakpoint()
3734 to breakpoint.c instead of directly writing breakpoint instructions.
3735 * sparcdep.c on remote_debugging,there is no need
3736 to remove signle step breakpoint instructions.
3737 * main.c added "-epoch" flag and "int epoch_interface" to main.c
3739 * printcmd.c - epoch interface sends lisp expressions to open up
3740 epoch windows on inspection.
3741 * valprint.c - added arrayprint, and addressprint and made adding
3742 format controls easier
3743 * wait.h added a couple of undef's because we were getting
3744 complaints about WSTOPSIG and WTERMSIG begin redefined.

3771 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
3772 should print ANSI qualifiers (such as `const' and `volatile').
3773 All callers changed to call with ANSI == 1, except from
3774 `check_method_stub', which uses old-style syntax.
3776 * symseg.h (struct fn_field): Remove unneccessary `args' field.
3777 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
3779 * values.c (check_stub_method): New function.

3814 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
3815 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
3816 when printing the type.
3818 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)

3833 * breakpoint.c (watch_command, bpstat_stop_status): Deal with
3834 exp_valid_block field correctly.
3836 * infrun.c (wait_for_inferior): When checking "don't even think
3837 about breakpoints" if stop_signal == SIGTRAP && trap_expected,
3838 also check step_resume_breakpoint.
3839 Insert breakpoints and continue (not step) if
3840 step_resume_break_address != NULL, even if another_trap.
3841 If trap_expected and we enter sigtramp, then set up a
3843 If trap_expected is set when we hit the step_resume_break,
