- below; they produce unwanted output in gdb mode in gnu-emacs.
+Thu Apr 11 17:19:41 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
- * gdb.texinfo: Spelled. Also removed index references from
- command editing section; the relevance/volume ratio was too low.
- Removed all references to the function index.
+ * target.h: Add to_doc and target_preopen.
+ target.c: Add target_preopen and target_command.
+ Remove target_info.
+ (add_target): Call add_cmd and mess with targetlist->doc.
+ core.c, exec.c, remote-eb.c, remote-nindy.c, remote-vx.c,
+ remote-vx.68.c, inftarg.c, remote.c: Add doc field to target struct.
+ Call target_preopen from open routine.
- * ns32k-opcode.h, ns32k-pinsn.c: Backed out changes of June 24th;
- haven't yet received legal papers.

+ (_initialize_main): Rename "info editing" to "show commands".
- * .gdbinit: Included message telling the user what it is doing.
+ * source.c: Rename directories_info to show_directories.
+ (_initialize_values): Rename "info directories" to "show directories".
- * symmetry-dep.c: Added static decls for i386_get_frame_setup,
- i386_follow_jump.
- * values.c (unpack_double): Added a return (double)0 at the end to
- silence a compiler warning.
+ * values.c: Rename convenience_info to show_convenience.
+ (_initialize_values): Rename "info convenience" to "show convenience".
- * printcmd.c (containing_function_bounds, asdump_command): Created
- to dump the assembly code of a function (support for xgdb and a
- useful hack).
- (_initialize_printcmd): Added this to command list.
- * gdb.texinfo [Memory]: Added documentation for the asdump
- command.
- * breakpoint.c (break_command_1, delete_breakpoint,
- enable_breakpoint, disable_breakpoint): Added extra verbosity for
- xgdb conditionalized on the new external frame_full_file_name.
- * source.c (identify_source_line): Increase verbosity of fullname
- prointout to include pc value.
- * stack.c: Added a new variable; "frame_changed" to indicate when
- a frame has been changed so that gdb can print out a frame change
- message when the frame only changes implicitly.
- (print_frame_info): Check the new variable in determining when to
- print out a new message and set it to zero when done.
- (up_command): Increment it.
- (down_command): Decrement it.
+ * copying.awk (_initialize_copying): Rename "info copying" to

- * m68k-pinsn.c (print_insn_arg [lL]): Modified cases for register
- lists to reset the point to point to after the word from which the
- list is grabbed *if* that would cause point to point farther than
- it currently is.
+ * symfile.c: Rename add_syms_command to add_symbol_file_command.
+ (_initialize_symfile, add_syms_addr_command):
+ Rename add-syms to add-symbol-file.
-Thu Jul 6 14:28:11 1989 Jim Kingdon (kingdon at apple-gunkies.ai.mit.edu)
+Thu Apr 18 18:08:30 1991 John Gilmore (gnu at cygint.cygnus.com)
- * valprint.c (val_print, value_print): Add parameter to control
- prettyprinting.
- valprint.h: New file containing constants used for passing
- prettyprinting parameter to val{,ue}_print.
- expprint.c, infcmd.c, printcmd.c, valprint.c, values.c:
- Change all calls to val{,ue}_print to use new parameter.
+ * symfile.h (free_named_symtabs): Rename from free_named_symtab.
+ * symfile.c (clear_symtab_users_once, cashier_psymtab,
+ free_named_symtabs): Move these routines from symmisc.c.
+ * symmisc.c (same): same.
+ (free_symtab): Make non-static.
+ * symtab.h (free_symtab): Declare as exported void fn now.
+ * dbxread.c (end_symtab, end_psymtab): Change comments.
+ (initialize_dbxread): Call dbx_new_init() in case the first
+ command is add-symbols.
+ * target.c (dummy_target): Permit add_syms_addr_command.
+
+Sat Apr 13 14:46:07 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ Permit symbols to be superseded when new symbol files have
+ been read in, particularly for VxWorks.
+
+ * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
+ to the main file, as well as to include files. Also, put global
+ functions into the global psymtab, to make "i fun" work.
+ (end_psymtab): Free named symtabs and psymtabs for a file, once a
+ new psymtab for it has been read.
+ * coffread.c (end_psymtab): Free named symtabs and psymtabs for
+ a file, once a new symtab has been read for it.
+ * mipsread.c: FIXME. We need to do the same for MIPS, but it
+ looks harder to determine the top-level block before it's been
+ queued to the psymtab list.
+
+ * symfile.c (symbol_file_add): Use filtered printing and wrap it.
+ If we have wiped out any old symbol tables, clean up at end of
+ symbol reading.
+ (symbol_file_command): Don't reference symfile_fns if it's zero.
+
+ * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
+ defines for the blocks of a blockvector that contain global and
+ file-static symbols and the first of the smaller scope contours.
+ * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
+ decode_line_1, make_symbol_completion_list): Use the above.
+ * coffread.c (end_symtab, patch_opaque_types): Ditto.
+ * dbxread.c (end_symtab): Ditto.
+ * expread.y (block): Ditto.
+ * mipsread.c (throughout): Ditto.
+ * symmisc.c (free_named_symtabs): Ditto.
+
+ * symtab.c (list_symbols): Process the first symbol of the
+ static psymbols list.
+ (types_info): Restore this function from its untimely #if 0.
+ It's not perfect, but it is better than nothing.
+ (_initialize_symtab): Restore "info types".
+
+Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ * m68k-stub.c: Remote stub for 680x0's, created from
+ rem-m68k.shar (which is removed).
+ * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
+ Remove RCS log stuff now that we use CVS and it blows our diffs.
+
+Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ * symmisc.c (free_named_symtab): Make it work, in its current
+ kludgy fashion. Change result to indicate if we blew away bkpts.
+ * dbxread.c (end_symtab): Accumulate result from
+ free_named_symtab and print warning if we blew user's state.
+ * symfile.h: free_named_symtab now returns an int.
+
+Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
+ is the first symbol read, even if not mainline.
+ (dbx_psymtab_to_symtab): symfile might be zero, cope.
+ * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
+ (set_section_command): New command ("section xxx yyy" -- should
+ be renamed to "set section xxx yyy" FIXME) which sets the
+ base address of a section of the exec file, overriding the
+ virtual address that BFD reports.
+
+Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ * exec.c: Add add_syms_addr_command to exec_ops, so you can
+ load symbols at any address while examining an exec file.
+
+Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
+ for printing the float info is host-dependent, not
+ target-dependent. FIXME.
+ * i386-pinsn.c: Move #includes to top, remove useless ones.
+ * i386-tdep.c: Don't bother including <.../reg.h> since we
+ don't use it (and it doesn't exist on host systems).
+
+ * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
+ Convert negative numbers properly.
+ (ieee_test): Make numbers really random; fix format arg.
+
+ * infcmd.c (attach_command, detach_command): Don't repeat on CR.
+ * core.c (core_detach): Unpush core_ops, which might not be on
+ top. We used to just pop the top, which broke things. Don't
+ need dont_repeat() any more.
+ (core_file_command): Psst! Don't repeat it.
+ * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
+ * expprint.c (print_subexp): Avoid switch fallthru on
+ BINOP_ASSIGN_MODIFY, so we can print += and such.
+ * frame.h: Fix typo.
+ * inflow.c (kill_command): After killing inferior, print our
+ current frame in the core file, if we have one.
+ (generic_mourn_inferior): When inferior dies, either select
+ the current frame (in the new target, e.g. core file), or
+ set both the current and selected frames to NULL.
+
+ Changes from Peter Schauer.
+
+ * infptrace.c: Avoid <sys/ptrace.h> on USG.
+
+ * Make all file names fit in 14 characters (sigh and damn!):
+ mv hp300hpux-xdep.c hp300ux-xdep.c
+ mv symmetry-xdep.c symm-xdep.c
+ mv symmetry-tdep.c symm-tdep.c
+ mv convex-opcode.h convx-opcode.h

+ * Makefile.dist, README, config.gdb, convex-pinsn.c,
+ tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
+ xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
+ names.
+
+ * command.c (user_info_1, user_info): New command for listing
+ the user-defined commands.
+
+Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ * dbxread.c (really_free_pendings): Clear file_symbols
+ and global_symbols after freeing them; otherwise, running
+ this function twice (if it appears twice on the cleanup
+ chain), we try to free things twice.
+
+ * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
+ based on text_addr (the address of text in core), not on addr (the
+ offset between text in the .o file and in core). This change
+ is from Peter Schauer.
+
+ * main.c: Define ALL_CLEANUPS as a cast of zero.
+ (return_to_top_level): Use it.
+ (main): Do all cleanups after each command run as part
+ of the gdb startup sequence. Also do all cleanups before
+ entering the command loop, and every time we exit the command
+ loop and reenter. Before, the cleanups from the startup sequence
+ were being left undone until the first error!
+ (command_loop): Rename do_nothing cleanup to command_loop_marker
+ so we can see it easily when examining the cleanup chain.
+ (init_signals): Add another do_nothing for signal handling.
+ (quit_command): Only try to kill target if it has execution.
+ Problems in the target stack got us into a state where
+ inferior_pid was nonzero but none of the targets had execution.
+ In this state you couldn't exit gdb.
+
+ * dbxread.c: Two changes from Peter Schauer.
+ (echo_command): Fflush output after an echo command.
+ (show_history): Pass all args to cmd_show_list.
+
+ * utils.c (init_malloc): Call mtrace to turn on tracing
+ if the environment variable MALLOC_TRACE is set to a file name.
+ * mtrace.c: Add source file which provides a log of every malloc,
+ free, and realloc to a trace file.
+ * mtrace.awk: Add source file which analyzes the trace file.
+ * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
+ (VERSION): Roll to 3.94.3.
+
+ * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
+ (check_duplicates): Don't bother with watchpoints.
+ (set_raw_breakpoint): Comment about danger of this routine.
+ (watch_command): Parse and eval all args before calling
+ set_raw_breakpoint.
+
+ * solib.c (find_solib): Avoid error in referencing memory to
+ see if any more shared libraries have been added. This is
+ particularly useful if the target has terminated. Bug reported
+ by Peter Schauer.
+
+ in bringing up 3.94.2 on the Sun-3.
+
+ * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
+ * breakpoint.c (enable_breakpoint): Check for valid watchpoint
+ expression (in scope) before reenabling watchpoint.
+ * signame.c (init_sigs): Add missing declaration of i, fix
+ sys_siglist declaration.
+ * source.c (list_command): Fixed range computation to use
+ lines_to_list ().
+ * stack.c (backtrace_command): Do not allow command if target has
+ no stack, print informative error message.
+ * target.c (target_command): Do not write into command line
+ because this fails if the target command is used in a user defined
+ command. [This change was enhanced by gnu to support any-
+ unique-prefix matching on target names.]
+ * valops.c (value_struct_elt): Avoid infinite loop on an
+ erroneous attempt to print the member of function (try p main.p).
+
+Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ * expread.y (name_no_typename): Avoid reduce/reduce errors
+ caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
+ Since the GDB parser really doesn't use name_no_typename in a
+ name-only context, the parser can't tell the diff between
+ names and numbers here. Avoid allowing a name_no_typename
+ to be a NAME_OR_*INT to resolve the conflict.
+
+Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+
+ * valprint.c (val_print_fields): bitfield printing didn't handle
+ byte order. Indirect through a few more fns to cope.
+
+ * values.c (modify_field): also cope with byte order.
+
+Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ Cleanup for release 3.94.2:
+
+ * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
+ include files. Roll version to 3.94.2.
-Mon Jul 3 22:38:11 1989 Randy Smith (randy at apple-gunkies.ai.mit.edu)
-
- * dbxread.c (,process_one_symbol): Moved extern declaration for
- index out of function to beginning of file.
-
-Mon Jul 3 18:40:14 1989 Jim Kingdon (kingdon at hobbes.ai.mit.edu)
-
- * gdb.texinfo (Registers): Add "ps" to list of standard registers.
-
-Sun Jul 2 23:13:03 1989 Jim Kingdon (kingdon at apple-gunkies.ai.mit.edu)
-
- * printcmd.c (enable_display): Change d->next to d = d->next so
- that "enable display" without args works.
-
-Fri Jun 30 23:42:04 1989 Jim Kingdon (kingdon at apple-gunkies.ai.mit.edu)
-
- * source.c (list_command): Made error message given when no
- symtab is loaded clearer.
-
- * valops.c (value_assign): Make it so that when assigning to an
- internal variable, the type of the assignment exp is the type of
- the value being assigned.
-
-Fri Jun 30 12:12:43 1989 Randall Smith (randy at apple-gunkies.ai.mit.edu)
-
- * main.c (verbose_info): Created.
- (initialize_main): Put "info verbose" into command list.
-
- * utils.c (screensize_info): Created.
- (_initialize_utils): Defined "info screensize" as a normal command.
-
- * valprint.c (format_info): Added information about maximum number
- of array elements to function.
-
- * blockframe.c (find_pc_partial_function): Again.
-
- * blockframe.c (find_pc_partial_function): Replaced a "shouldn't
- happen" (which does) with a zero return.
-
- * main.c (dont_repeat): Moved ahead of first use.
-
-Thu Jun 29 19:15:08 1989 Randall Smith (randy at apple-gunkies.ai.mit.edu)
+ * coffread.c (init_stringtab): Read length into unsigned char
+ array before swapping; don't assume 32-bit longs.
+
+ * target.c (target_info): Don't bother with get_sym_file, just use
+ the symfile global variable.
+ * symtab.h, symfile.c (get_sym_file): Delete it.
+
+ * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
+ (define_symbol): Set symbol line number to 0 if not gcc-compiled.
+ (read_type): Replace one more error() with complain().
+
+ * mipsread.c (parse_partial_symbols): Replace printf with complain.
+
+ * i960-tdep.c: Fix copyright attribution.
+
+ * config.gdb: Quote all backquotes in doublequotes. You can
+ quote me on that. BSD 4.4 shell found this one.
+
+ * infptrace.c (throughout): The third argument to ptrace is an
+ int *, not an int.
+
+ * infrun.c (wait_for_inferior): When program has terminated, we
+ have to call target_terminal_ours before we pop that target off
+ the stack (e.g. before a call to target_kill or
+ target_mourn_inferior). This fixes problem where a program
+ terminates, then GDB stops for (tty output) and you have to type
+ "fg" to the shell to resume it. FIXME: This code for what to
+ do after termination really should be in normal_stop instead.
+
+ * gdbcore.h (read_memory_check): Change declaration; it changed
+ names months ago.
+
+ * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
+ 4.4 prereleases, this avoids a bug in their sgtty compatability
+ support.
+ * remote.c: Use terminal.h rather than hand-rolling the same.
+
+ * signame.c, signame.h (psignal): Arg is unsigned, not int.
+ * utils.c (strsave, strstr): Fix arg types.
+ * valprint.c (val_print): lint
+
+ MIPS symbol table support from Per Bothner:
+
+ * symfile.c (symtab_fns): Remove initializer table that needs to
+ be hacked for each new symbol file format supported.
+ (add_symtab_fns): New function, chains symbol table
+ handlers into the global list.
+ (symfile_init): Search this list.
+ * symfile.h: Add next pointer, declare add_symtab_fns.
+ * coffread.c (_initialize_coffread): Call add_symtab_fns.
+ * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
+
+ * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
+ symbol *). Thus, we no longer need the hack to trash
+ pst->filename. Good, since that hack confused code in symfile.c!
+
+ (reorder_symtabs, destroy_all_symtabs): Removed static
+ all_symtabs, which was used to qsort symtabs in reorder_symtabs.
+ Instead, the latter now uses a temporary array (stack-allocated
+ from an obstack, and then freed).
+
+ (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
+ haven't been set in the outermost stBlock of a procedure. This was
+ a problem with f77 binaries on Ultrix 4.?.
+
+ (new_symtab, new_symbol, new_type): Continue changing code to use
+ obstacks more and otherwise conform to dbxread internal style.
+ Made the free_code of symtabs be free_linetable (as in dbxread)
+ instead of free_contents. This implies memory leaks when reading
+ a new symbol table, until the conversion is finished. Did change
+ (struct symbol) and (struct type) to be allocated on the
+ symbol_obstack. Blocks and blockvectors are among the things
+ still "leaking."
+
+ * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
+ tested much, but it solved one problem (reported by Meissner), and
+ cleans up some other things. The problem happened when an
+ included file contains actual code (functions) and not just
+ definitions. The mips coff is a little inconvenient there, since
+ it may cause a procedure to be mapped to the wrong psymtab.
+
+ * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
+ * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
+ this will need work for the new core paradigm.
+
+ Opcode patches from the net:
+
+ * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
+ ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
+ missing altogether - they are added here. From Bruce Bauman.
+ * mips-opcode.h: The low mask for C0 instructions was too small.
+ From Garrett Lau. I modified the fix to check the entire 32-bit
+ opcode.
+
+ * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
+ Bauman.
+
+Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
+
+ * dbxread.c (read_type): Pointer subtraction (value_sub in
+ valarith.c) sometimes failed because the types of the
+ pointers being subtracted were not identical.
+ These differed because dbxread.c was allocating pointer types
+ using dbx_alloc_type+smash_to_pointer_type instead of
+ lookup_pointer_type. I failed to find a justification for the
+ former, so I changed it to use the latter. Similarly, I
+ replaced smash_to_function_type by lookup_function_type,
+ and smash_to_reference_type by lookup_reference_type.
- * vax-opcode.h: Made minor modifications (moved an instruction and
- removed a typo) to bring this into accord with gas' table; also
- changed copyright to reflect it being part of both gdb and gas.
-
- * m68k-opcode.h: Added whole scads and bunches of new stuff for
- the m68851 and changed the coptyrightto recognize that the file
- was shared between gdb and gas.
-
- * main.c (stop_sig): Use "dont_repeat ()" instead of *line = 0;
-
- * core.c (read_memory): Don't do anything if length is 0.
-
- * Makefile: Added readline.c to the list of files screwed by
- having the ansi ioctl.h compilation with gcc.
-
- * config.gdb: Added sun4os3 & sun4-os3 as availible options.
-
-Wed Jun 28 02:01:26 1989 Jim Kingdon (kingdon at apple-gunkies.ai.mit.edu)
-
- * command.c (lookup_cmd): Add ignore_help_classes argument.
- (lookup_cmd_1): Add ignore_help_classes argument.
- command.c, main.c: Change callers of lookup_cmd{,_1} to supply
- value for ignore_help_classes.
-
-Tue Jun 27 18:01:31 1989 Randall Smith (randy at apple-gunkies.ai.mit.edu)
-
- * utils.c (print_spaces_filtered): Made more efficient.
- * defs.h: Declaration.
- * valprint.c (val_print): Used in a couple of new places.
-
-Mon Jun 26 18:27:28 1989 Randall Smith (randy at gluteus.ai.mit.edu)
-
- * m68k-pinsn.c (print_insn_arg ['#', '^']): Combined them into one
- case which always gets the argument from the word immediately
- following the instruction.
- (print_insn_arg ["[lL]w"]): Make sure to always get the register
- mask from the word immediately following the instruction.
-
-Sun Jun 25 19:14:56 1989 Randall Smith (randy at galapas.ai.mit.edu)
-
- * Makefile: Added hp-include back in as something to distribute.
-
- * stack.c (print_block_frame_locals): Return value changed from
- void to int; return 1 if values printed. Use _filtered.
- (print_frame_local_vars): Use return value from
- print_block_frame_locals to mention if nothing printed; mention
- lack of symbol table, use _filtered.
- (print_frame_arg_vars): Tell the user if no symbol table
- or no values printed. Use fprintf_filtered instead of fprintf.
- * blockframe.c (get_prev_frame_info): Check for no inferior or
- core file before crashing.
-
- * inflow.c (inferior_died): Set current frame to zero to keep from
- looking like we're in start.
-
-Sat Jun 24 15:50:53 1989 Randall Smith (randy at gluteus.ai.mit.edu)
-
- * stack.c (frame_command): Added a check to make sure that there
- was an inferior or a core file.
+ * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
+ _initialize_mipsread): corresponding changes.
+
+ * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
+
+ * source.c (mod_path): Do tilde_expand on each component of the path,
+ rather than on the (list of) paths as a whole.
+ (print_source_lines): Set first_line_listed in addition to
+ current_source_symtab and current_source_line. If the source was
+ not findable, after a "dir" command to fix the problem,
+ a "list" would get the wrong lines.
+
+ While I was there... (gnu):
+
+ * dbxread.c (read_type): Change error to complaint.
+
+Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ First attempt at detailed understanding of symbol table memory alloc.
+
+ * dbxread.c (dbx_symfile_read): Free our string table if we
+ aren't the mainline. Free the "info" struct since we're done with
+ it.
+ (init_psymbol_list): Free any previously allocated psymbol lists.
+ (): FIXME: Should realloc-down the psymbol lists when done reading
+ the main symbol file?
+
+ * symmisc.c (free_symtab): Free fullname field too.
+
+ * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.

+
+ * i960-tdep.c (examine_prologue): Add new argument limit,
+ which stops the scan at the end of the prologue, or at the PC.
+ This fixes a problem where it walks down into the code for the
+ user's statements if that code looks like function prologues.
+ Mark Fox and I have been bouncing this code back and forth, making
+ small changes to it. Callers changed to match.

+
+ * dbxread.c (really_free_pendings): Don't free pending_blocks;
+ they are in an obstack.
+ (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.

+ instructions.
+
+ * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
+ obsolete Intel versions in favor of vxgdb versions.

+ (child_files_info): Clean up message a bit.
+ (child_ops): Use child_attach, not child_open, to attach.
+
+ * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
+ set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
+ findvar.c to here, since it depends on the contents of the
+ shadow_contents of breakpoints, but keep if #if 0 since it is

+ from i960-tdep.c.
+
+ * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.

+ (nindy_fetch_registers, nindy_store-registers): Translate between

+ and "ok" if we read their symbols OK. Clarify output in general.
+ (vx_attach, vx_detach, vx_kill): Add these commands.
+ (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
+ (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
+ "info files" output, and create_inferior, since we already have
+ an inferior.
+
+ * stack.c (frame_info): Replace Frame_unknown with 0.
+ (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
+ (return_command): Pop until the PC matches as well as the FP,
+ so it works even if the FP is shared with another function,
+ as in "frameless" or "leaf" procedures.
+
+ * symfile.c (load_command): renamed from add_file_target_command.
+ (add_syms_addr_command): renamed from add_file_addr_command.
+ (add_syms_command): Stub to call target_add_syms.
+ (_initialize_symfile): Change command names and descriptions,
+ add-file => add-syms, and load from alias to its own command.
+
+ * target.c (kill_or_be_killed, maybe_kill_then_attach,
+ maybe_kill_then_create_inferior): Default for attempts to start
+ a process, if one is already running, is to ask about killing
+ it and retry if yes.

+ MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
+ REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
+ are now 10 byte extendeds, not 8 byte doubles.
+ (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
+ for nindy versus vxworks targets. FIXME, this should possibly go
+ in the target vector.
+ (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
+ frame_saved_regs and arg pointer with each frame.
+ (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.

+ (ADDITIONAL_OPTION_HANDLER): use target_load, not
+ target_add_file.
+
+ * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
+ startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.

-
- * dbxread.c (read_ofile_symtab, psymtab_to_symtab): Moved cleanup
- of undefined types to psymtab_to_symtab. That way it will be

- help reduce infinite loops).
-
- * symtab.h [misc_function_type]: Forced mf_unknown to 0.
- * dbxread.c (record_misc_function): Cast enum to unsigned char (to

- when we're done.
-
- * dbxread.c (psymtab_to_symtab, psymtab_to_symtab_1): Broke
- psymtab_to_symtab out into two routines; made sure the string
- table was only readin once and the globals were only scanned once,

-
- * main.c (symbol_completion_function): Always complete on result

-
- * symtab.c (make_symbol_completion_function): Fixed typo; strcmp
- ==> strncmp.
-
- * dbxread.c (read_dbx_symtab): Change 'G' case to mark symbols as

- before inserting breakpoints.
-
- * infrun.c (wait_for_inferior): Inserted special case to keep
- going after taking a signal we are supposed to be taking.

- actions of "directory" command (taking multiple directory names at
- the same time).
+ * valops.c (value_cast): Avoid looking up names of types whose
+ name we don't know, to prevent coredump. Sun CC produces typedef
+ rtx and the name of *rtx is zero...
- * m68k-opcode.h: Replaced the version in gdb with an up-to-date
- version from the assembler directory.
- * m68k-pinsn.c (print_insn_arg): Added cases 'l' & 'L' to switch

- not today).
-
- * expread.y (yylex): Added SIGNED, LONG, SHORT, and INT keywords.
- [typename]: Created.
- [typebase]: Added rules for LONG, LONG INT, SHORT, SHORT INT,

- standard).
-
- * Makefile: Included .c.o rule to avoid sun's make from throwing
- any curves at us.
-
- * blockframe.c: Included <obstack.h>
-
- * command.c (lookup_cmd): Clear out trailing whitespace.
-
- * command.c (lookup_cmd_1): Changed malloc to alloca.
+ tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
+ for ../include/a.out.encap.h. This might not work now that BFD
+ is separately compiled. Instead, BFD support for encap will have
+ to translate machine type 29k into the right COFF_MAGIC.
+
+ * infcmd.c: Remove references to inferior_pid that aren't used
+ in actual ptrace calls; use target_has_execution, etc.
+ (have_inferior_p): Remove function.

-
- * valops.c (value_zero): Add an argument for type of lval.

+Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ Roll in changes from vxgdb-5.0.1:
+
+ * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
+ symbol in its raw form, we are processing an unlinked ".o" file.
+ See if the target environment has assigned it an address, using
+ target_lookup_symbol (VxWorks does), and enter it into the symtab
+ that way.
+
+ * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
+ 68k versions for a simpler version that assumes zero FP at bottom.

+ (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
+ (vx_open): Rearrange code that attaches to target and reads
+ symbols for all loaded modules, to work if some of the modules
+ are not accessible. Add symbol_stub() and add_symbol_stub()
+ as callbacks from catch_errors(). Allow connect attempt to be
+ interrupted painlessly with ^C (FIXME, there are still some bugs
+ if the interrupt happens during symbol reading.). Print
+ final message with puts_filtered, since symbol messages are
+ now filtered too.
+
+ Misc cleanup:
+
+ * main.c (catch_errors): Only print errstring if non-null.
+ (command_loop): Avoid an ioctl per command to test ISATTY.

+ * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
+ * remote-vx.c: include <sys/time.h> for HPUX.
+ * hp300hpux-xdep.c (fetch_core_registers): Rewrite old

+ (FIXME: Its copyright assignment is not on record.)
+ * xgdb.c: Update include files to X11R4 (Xaw crud).
+ (xgdb_display_source, create_text_widget): fix call to
+ get_filename_and_charpos. Rewack source window stuff for X11R4

+ * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
+ obstack_int_grow, obstack_int_grow_fast): Eliminate
+ cast on left of assignment, which gives MIPS cc fits and is
+ not Standard C.
+
+ * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
+ F_ALIAS. Use printf, not fprintf, when not passing a file
+ pointer...
+ (compare_opcodes): Check that identical instructions have
+ identical opcodes, complain otherwise.
+
+ * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
+ was reported by Roland McGrath.
+ (unimp): Only match if exactly zero instruction. (Roland)
+ (branches and traps): Generate all variations of these
+ instructions with macros, based on a single call that defines
+ each condition name and its binary representation.
+ (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
+
+ * valprint.c (val_print_fields): Take, and use, format parameter.
+ This means that "p/x struct" again prints the elements in the
+ desired format. Changed callers.
+
+ * stack.c (frame_info): Use filtered output, and indicate wrap
+ points. Remove kludgy formatting designed to avoid line wrap.
+
+ * utils.c (wrap_here): If the line is already full (because
+ we had printed a long indent or long wrapped string), do an
+ immediate newline-and-indent.
+
+ * m68k-pinsn.c (print_insn_arg): Bugfix from
+ instruction is incorrectly disassembled as bkpt #8.
+
+ * dbxread.c (end_psymtab): Bugfix from Peter Schauer
+ breakpoint in a *.y file gdb will say Reading in symbols for *.y...
+ and then will dump core (sometimes). I traced it back to an
+ uninitialized symfile_name in psymtab_to_symtab.
+ (const_vol_complaint): Add quotes to message.
+ (define_symbol): Only believe line number if gcc_compiled.
+ Avoid allocating symbol if we will not return it.
+
+ Add target strata support so that newly established targets go
+ into their right place in the target stack (e.g. a new exec file
+ doesn't wipe out the ability to access the running process).
+
+ * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
+ remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
+ and initialize it properly in all the targets.
+
+ * target.h: Document strata. Change return type of push_target.
+
+ * target.c (nomemory): new function for dummy memory access.
+ (tcomplain): Rename complain, now also used in symfile.c.
+ (push_target): Push targets within strata. New return value shows
+ whether new target is on top of stack or not. Always keep dummy
+ target on stack.
+ (target_files_info): Ignore dummy target.
+
+ * core.c (core_open): Warn user, and skip accessing file, if the
+ core target is not the topmost target in the stack.
+ * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
+ already handled.
+
+ * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
+ target_ops, it doesn't belong there since we have no regs there.
+ Change name of target from machine => memory to clarify.
+
+Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
+
+ * Freeze version 3.93 for release.
+
+ * Makefile.dist: Handle vx-share and nindy-share subdirs
+ properly when building gdb.tar.Z.
+
+ * symtab.c: lint; add no_symtab_msg to consolidate the messages
+ printed in various places, so I could change just one copy.
+
+ * dbxread.c, coffread.c: Change references to bfd->iostream
+ to cast to FILE *, now that BFD avoids needing types defined
+ in other header files.
+
+Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
+ infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
+ sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
+ (actually gcc -Wall).
+
+ * dbxread.c: Remove first_global_sym, last_global_sym, since
+ they are never referenced.
+
+ * defs.h (baud_rate): Declare.
+ main.c: Define it, and add the -b option to set it.
+
+ * gdb-int.texinfo: Add text on how to define a new host or target
+ architecture, prompted by Per Bothner's questions about MIPS
+ support.
+
+ * gdb.texinfo: Document "complaints". Change doc of -q since
+ gdb no longer prints the copyright and blurb if you specify a file
+ name to be debugged (just like Emacs). Add doc for Nindy-specific
+ command line flags for specifying target serial port and such.
+ Update copyright to 1991.
+
+ * gdbcore.h: Remove a large mass of now-useless crud, since BFD
+ has taken over for us the job of ripping up executable files. The
+ crud caused Per Bothner's port to not compile.
+
+ * infrun.c (normal_stop): Avoid printing "Program exited
+ normally" if we are in batch mode. This allows a GDB which
+ executes a program on a target system, to behave like a Unix
+ command (input from stdin, output to stdout, no extraneous
+ output).
+
+ * main.c (main): Allow additional machine-dependent command line
+ options to be specified with the ADDITIONAL_OPTIONS,
+ ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
+ ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
+ processing to occur just before the main loop with
+ BEFORE_MAIN_LOOP_HOOK.
+ (main): If a "core file" argument is specified, and it is not a
+ core file, try it as a process ID to attach.
+ (symbol_completion_function): Attempt to cope with
+ "show screen-" TAB, not very successfully. This needs more work,
+ FIXME.
+ (batch_file): New function, returns whether we are reading
+ commands from an interactive tty on stdin, or from somewhere else.
+ Called by normal_stop since it doesn't get from_tty passed down
+ to it like many commands do.
+
+ * remote-nindy.c: Handle command line options for nindy
+ connection.
+ (nindy_before_main_loop): Prompt user for tty name if they
+ don't specify it before getting to the interactive command loop.
+
+ * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
+ and -r command line options. Also add hook before main loop
+ to make it easy to specify a tty.
+
+ * TODO: More things to do, one done.
+
+Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
+
+ * dbxread.c: Make complaint() calls pass pointer, not struct.
+ Add complaints about badly formatted C++ type information
+ (const/volatile indicator, and parse errors resulting in
+ error_type). Fix C++ virtual member fn comment.
+ (read_struct_type): Avoid bumping pointer if we got a parse
+ error; this prevents our walking beyond the end of a string.
+ Terminate loop on null char as well as semicolon.
+ (process_one_symbol): Fix the LBRAC fix so that it uses the
+ last previous SLINE, FUN, or SO record's PC address. C++ debug
+ symbols did not have SLINE records in a useful order compared
+ to the LBRAC records.
+ (define_symbol): Handle "catch" records.
+
+ * symtab.c (check_stub_type): Added new complain
+ `stub_noname_complain' and added a consistency check to
+ keep the debugger from crashing when finishing from an
+ exception frame. A real fix will be needed later.
+
+Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ * infcmd.c (attach_command): Make global.
+
+ * Makefile.dist (REMOTE_OBS): Make these compile by default,
+ but make them easy to comment out. Perhaps later they should
+ be enabled by what CPU you configure for? FIXME.
+ (VERSION): Roll to 3.93.
+ (pinsn.o): Remove rule for obsolete file.
+ (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
+
+ Run down a problem that manifested by printing the wrong function
+ name in stack traces of read_ofile_symtab. Turned out that the
+ problem was the SunOS 4.1.1 (and previous) C compiler outputs
+ the LBRAC symbol with an address in the *data* segment, which
+ blew our binary search through the blocks.
+
+ * dbxread.c: Use the complain() facility consistently to bitch
+ about problems in the symbol file we are reading.
+ (finish_block): Add code to check the nesting of the blocks;
+ complain and Procrust them to fit if wrong.
+ (make_blockvector): Check the order of the blocks, complain
+ [but don't cope] if wrong.
+ (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
+ symbols to be sure their PC value is greater than the last SLINE
+ (line number) symbol we've seen, complaining and adopting the
+ SLINE PC value if wrong.
+
+ * symfile.h (struct complaint, complaint_root, complain,
+ clear_complaints): Add.
+ * symfile.c (complain, complaint_root, clear_complaints): Add
+ facility to deal with non-fatal complaints and to regularize their
+ suppression.
+ (symbol_file_add): Clear complaint counters to allow new complaints.
+ (initialize_symfile): Add 'set complaints' and 'show complaints'.
+
+ * dbxread.c (dbx_symfile_read): Remember the address and size
+ of the string table for the main symbol file, so we won't read it
+ more than once.
+ (dbx_psymtab_to_symtab): Fix the check for main symbol file,
+ to avoid reading the string table yet again. Lint.
+ (throughout): Improve filtered output, including word wrap.
+ (read_range_type): Improve Bothner's fix to handle other types too.
+
+ * utils.c: Improve line wrap implementation. Handle unlimited
+ width by making chars_per_line unsigned.
+ (puts_filtered): New, easy, function.
+
+ * defs.h (puts_filtered): add.
+
+ * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
+ call the identical sort_symtab_syms() in symfile.c instead.
+
+ * expread.y: Suggest the `file' command rather than `symbol-file'.
+
+ * command.h (enum var_types): Add zinteger for seroable
+ unsigned integer.
+ * command.c (do_setshow_command): Handle var_zinteger. Restructure
+ nested if's into a switch.
+
+ * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
+ we did not stop because of a breakpoint (it must have been for
+ some other reason, like a "stepi"), so don't print anything.
+
+ * symtab.c: Include <sys/types.h> all the time. Now that BFD
+ doesn't include <sys/types.h>, old SunOS's require it for
+ <sys/stat.h>.
+
+
+ A test port of gdb-3.92.6 to the Sony NEWS.
+
+ * Makefile.dist
+ Don't normally link in remote- or vx stuff.
+ Some of it doesn't compile, and it wastes space for 99% of the users.
+ Remove reference to no-longer-used HAVE_VPRINTF.
+ Fixed BFD_DEP typo to BFD_DIR.
+ * dbxread.c
+ Fix cast in arg to bfd_h_getlong.
+ Make char *prefix be const.
+ Fix how certain range types are mapped into builtin unsigned int types.
+ * infrun.c
+ Remove 2 #includes. They cause errors (on Sony, at least),
+ and aren't needed (they wern't in earlier versions).
+ * printcmd.c
+ print_address_symbolic should never demangle labels
+ (since it prints *assembler-level* labels).
+
+ [This was superseded by the change to printcmd below.]
+
+ * utils.c
+ Add some "volatile" return types to avoid warnings.
+ If MISSING_VPRINTF add vprintf function and not just macro
+ (since vprintf is used in printcmd.c).
+ * valprint.c
+ Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
+ (The latter isn't grokked by some PCC-based compilers.)
+
+ [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
+
+ Make chunk size of dont_print_obstack 32*4 instead of default 4096.
+ * nindy-share/coffstrip.c
+ Added some forward declarations (otherwise, gcc complains
+ about implicit extern redefined as static).
+
+Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ Changes inspired by Per Bothner:
+ * printcmd.c (print_address_symbolic): Take additional parameter
+ specifying whether to demangle.
+ (print_address): Pass in asm_demangle to control demangling.
+ (print_address_demangle): New fn, takes explicit arg to control
+ demangling.
+ * utils.c: Add new vars demangle and asm_demangle, and let them
+ be set and shown.
+ (fputs_demangled): If !demangle, just print the argument.
+ (fprint_symbol): If !demangle, just print raw symbol.
+ * valprint.c (val_print): Call print_address_demangle rather than
+ print_address, to cause demangling to depend on the global
+ rather than assembler-level demangling setting.
+ * WHATS.NEW, gdb.texinfo: Document.
+
+ * main.c (show_command): Show all settings if no arg.
+ (initialize_main): Make "info set" the same as naked "show".
+ * command.c (cmd_show_list): Handle prefix commands in the
+ list, and print the name of the setting as well as its English
+ description and value.
+
+ Allow gdb functions to specify where a line should wrap if it
+ exceeds the size of a terminal line. Use it to make the output
+ prettier.
+ * utils.c (set_screen_width_command): New fn, mallocs a buffer
+ of the right size when screen width changes.
+ (set_screensize_command, screensize_info): Remove #if 0'd fns.
+ (wrap_here): New fn, indicates a point in the output where we
+ should wrap the line rather than just letting it overflow at a
+ random place.
+ (fputs_filtered): Implement wrapping.
+ (n_spaces): New fn, returns a pointer to N spaces.
+ (print_spaces_filtered): Use n_spaces.
+ * defs.h (n_spaces): Declare.
+ * stack.c (print_frame_info): Wrap with 4-space indent after
+ fn name and before filename and line number.
+ * printcmd.c (print_frame_args): Wrap with 4-space indent
+ before each argument name is printed.
+ * valprint.c (value_print): Wrap with no indentation before
+ each repetition.
+ (val_print_fields): Wrap with indentation relative to nesting
+ level before each field name.
+ (val_print): Wrap with nesting indentation before array elements.
+ * command.c (do_setshow_command): Avoid extra newlines,
+ wrap with 4-space indent around values printed, end with period.
+ * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
+
+ * breakpoint.c (breakpoint_1): Implement addressprint for
+ "info breakpoints" display. Change file name and line number
+ format to " at file:nnn" rather than " (file line nnn)".
+ * gdb.texinfo: Document.
+
+
+Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ Frozen for gdb-3.92.6 release.
+
+ README, WHATS.NEW: Update for 3.92.6 release.
+
+ tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
+ coffread.o from configs since it is now built by default.
+ tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
+ i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
+ pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
+ from configs since it is now built by default.
+
+ Makefile.dist: Update for release 3.92.6. Handle files that
+ have been moved to ../include, ../getopt, or ../bfd. Add
+ saber.suppress and tests directory. Add config.status to
+ the release (it will say "none").
+
+ coredep.c: Minor formatting fixes.
+
+ These changes were made in early December but only checked in now:
+ * nindy-share/Onindy.c, nindy-share/coffstrip.c,
+ nindy-share/nindy.c: lint
+ * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
+ register values coming back from the target; we store values
+ in target byte order everywhere.
+
+Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
+
+ * valprint.c (cplus_val_print, val_print_fields): New functions,
+ which print C++ objects. They conspire to avoid printing a
+ virtual base class more than once, following all the twists and
+ turns of C++ virtual base rules.
+ (val_print): Call the above rather than do it by hand.
+
+ * symfile.c (symbol_file_add): Only reset symfile_mtime for main
+ symbol file, not for added files like shared libs. This really
+ needs to be generalized to a timestamp per file.
+
+ * core.c (cleanup_core): Avoid coredump if no core file.
+
+ * config.gdb: Accept -host or -target in place of +host or
+ +target.
- * dbxread.c (symbol_file_command): Made use of alloca or malloc
- dependent on macro define.
+ * coffread.c (find_linenos): Avoid desupported BFD interface
+ to line numbers. We still read them manually rather than using
+ BFD's "generic" features.
-Thu May 4 15:47:04 1989 Randall Smith (randy at apple-gunkies.ai.mit.edu)
+ * gdbrc.tex, threecol.tex: Add GDB reference card and its
+ formatting code.
+ Makefile.dist: Add refcard to OTHERS list for creating tar files.
- * Makefile: Changed READLINE_FLAGS to SYSV_DEFINE and called munch
- with it also.
- * munch: Check first argument for -DSYSV and be looser about
- picking up init routines if you find it.
+ * Makefile.dist: Eliminate use of $< in explicit targets.
- * coffread.c: Made fclose be of type int.
+ * readline/Makefile: Use $< rather than $*.c, which does not
+ include the VPATH in GNU Make.
- * breakpoint.c (_initialize_breakpoint): Put "unset" into class
- alias.
+ * tconfig/i960-bout, tconfig/i960-coff: These are identical
+ copies of tconfig/i960, added for global configuration
+ compatability. All i960 versions can read both coff and b.out.
-Wed May 3 14:09:12 1989 Randall Smith (randy at apple-gunkies.ai.mit.edu)
+ * tm-88k.h: Fix multiline macro that lacked \'s. Remove
+ COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
+ automaticaly.
- * m-sparc.h [STACK_END_ADDR]: Parameterized off of
- machine/vmparam.h (as per John Gilmore's suggestion).
+ * TODO: Think of more things to do.
- * blockframe.c (get_prev_frame_info): Changed this function back
- to checking frameless invocation first before checking frame
- chain. This means that a backtrace up from start will produce the
- wrong value, but that a backtrace from a frameless function called
- in main will show up correctly.
+Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
- * breakpoint.c (_initialize_breakpoint): Added entry in help for
- delete that indicates that unset is an alias for it.
+ tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
+ of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
+ 64-bit float conversion.
- * main.c (symbol_completion_function): Modified recognition of
- being within a single command.
+ tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
+ equivalent to sun?os4 so global config works.
-Tue May 2 15:13:45 1989 Randy Smith (randy at gnu)
+Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
- * expread.y [variable]: Add some parens to get checking of the
- misc function vector right.
+
+ * main.c: Only declare linesize once; declare pagesize not at
+ all, since it is never used.
+ (main): Clear newly allocated line before it is used.
-Mon May 1 13:07:03 1989 Randall Smith (randy at apple-gunkies.ai.mit.edu)
+Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
- * default-dep.c (core_file_command): Made reg_offset unsigned.
+ Further stabilization for the Intel 960.
- * default-dep.c (core_file_command): Improved error messages for
- reading in registers.
+ * Makefile.dist: Parameterize the location of the "include"
+ and "bfd" directories, as well as "getopt". Add symfile.c.
+ Link in both dbxread and coffread. Fix up "make depend" to
+ rewack the locations of include, bfd, and getopt in its output.
- * expread.y: Allowed a BLOCKNAME to be ok for a variable name (as
- per C syntax).
+ * README: Document moving include files, improve some of
+ the other doc.
- * dbxread.c (psymtab_to_symtab): Flushed stdout after printing
- starting message about reading in symbols.
+ * coffread.c: Move common code out to symfile.c. Change
+ symbol_file_command style interface to use new *_symfile_init
+ and *_symfile_read interface under BFD. Use BFD internal
+ info to locate line table, symbols, etc.
- * printcmd.c (print_frame_args): Switched starting place for
- printing of frameless args to be sizeof int above last real arg
- printed.
+ * core.c (core_fetch_registers): Rename to get_core_registers
+ to avoid confusion with fetch_core_registers.
+ (register_addr): Move to coredep.c, which is already machine
+ dependent. This leaves core.c pretty clean of dependencies.
- * printcmd.c (print_frame_args): Modified final call to
- print_nameless_args to not use frame slots used array if none had
- been used.
+ * coredep.c (register_addr): Accept this routine from core.c.
- * infrun.c (wait_for_inferior): Take FUNCTION_START_OFFSET into
- account when dealing with comparison of pc values to function
- addresses.
+ * dbxread.c: Move common code (with coffread.c, etc) into new
+ symfile.c. Each psymtab now contains a pointer to the
+ format-dependent function that knows how to read it in. Make
+ some things static.
+ (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
+ (process_one_symbol): Add code to complain about a "compiler bug
+ we muzzle here", if we actually see it.
- * Makefile: Added note about compiling gdb on a Vax running 4.3.
+ * eval.c (evaluate_subexp): Insert missing "break" statements
+ in code that determines whether a variable is an lvalue in
+ memory, register, or whatever. I detected this via a compiler
+ bug in which it *almost* mashed out the whole switch statement.
-Sun Apr 30 12:59:46 1989 Randall Smith (randy at apple-gunkies.ai.mit.edu)
+ * gdb-int.texinfo: Add minor sections on configuring gdb for
+ release, and about the README file.
- * command.c (lookup_cmd): Got correct error message on bad
- command.
+ * infcmd.c (registers_info): Fix formatting somewhat. Still
+ not as pretty as before, but it handles byte swapping.
- * m-sun3.h [ABOUT_TO_RETURN]: Modified to allow any of the return
- instructions, including trapv and return from interupt.
+ * remote-nindy.c: If data cache routines are interrupted while
+ waiting for the remote end, be sure that any uninitialized cache
+ blocks are on the free list, not on the valid list!
- * command.c (lookup_cmd): If a command is found, use it's values
- for error reporting and determination of needed subcommands.
+ * symfile.h: Flesh out this header file with all the various
+ routines and variables that have been merged in from dbxread.c
+ coffread.c, and symtab.c to symfile.c.
- * command.c (lookup_cmd): Use null string for error if cmdtype is
- null; pass *line to error instead of **.
+ * symfile.c: New file, containing code common to dbxread.c,
+ coffread.c, and some code from symtab.c. All generic code for
+ reading symbol files should be in here now.
+ (unrecord_misc_function): Remove unused function.
- * command.c (lookup_cmd_1): End of command marked by anything but
- alpha numeric or '-'. Included ctype.h.
+ * symtab.h: Remove file-reading things to symfile.h.
-Fri Apr 28 18:30:49 1989 Randall Smith (randy at apple-gunkies.ai.mit.edu)
+ * symtab.c: Remove file-reading things to symfile.c.
- * source.c (select_source_symtab): Kept line number from ever
- being less than 1 in main decode.
+ * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
+ to decode i960 fault types.
-Wed Apr 26 13:03:20 1989 Randall Smith (randy at apple-gunkies.ai.mit.edu)
+ * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
+ target.c: Change type of the "resume" function from int to void,
+ since its result was never used.
- * default-dep.c (core_file_command): Fixed typo.
+Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
- * utils.c (fprintf_filtered): Don't use return value from
- numchars.
+ * main.c: Replace "stupid" with "caution"; you now "set caution
+ on or off".
- * main.c, command.c (complete_on_cmdlist): Moved function to
- command.c.
+ * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
- * command.c (lookup_cmd): Modified to use my new routine. Old
- version is still there, ifdef'd out.
+ * infcmd.c (do_registers_info): Call val_print to deal with the
+ byte order of the registers being printed. FIXME, this makes
+ the formatting of the output uglier.
- * command.c, command.h (lookup_cmd_1): Added a routine to do all
- of the work of lookup_cmd with no error reporting and full return
- of information garnered in search.
+ * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
+ defined, call it for signals the debugger doesn't itself use.
+ The i960 uses this for more detailed fault information.
-Tue Apr 25 12:37:54 1989 Randall Smith (randy at gluteus.ai.mit.edu)
+ * remote.c (remote_open): If arg is null, print help rather than
+ dumping core.
- * breakpoint.c (_initialize_breakpoint): Change "delete
- breakpionts" to be in class alias and not have the abbrev flag
- set.
+ * sparc-xdep.c (register_valid): Avoid declaring size, since
+ various modules will think of various sizes depending on the
+ architecture of their tm-file. FIXME, we need protection against
+ actually entering one of those modules, which would clobber
+ storage if not for the target architecture compiled into gdb.
- * main.c (symbol_completion_function): Fix to correctly complete
- things that correspond to multiword aliases.
+ * stack.c (up_command, down_command): Always print the frame
+ you arrive at.
+ (up_silently_command, down_silently_command): New commands
+ for use in scripts.
- * main.c (complete_on_cmdlist): Don't complete on something if it
- isn't a command or prefix (ie. if it's just a help topic).
+ * i960-pinsn.c (reg), i960-tdep.c: Lint.
- * main.c (symbol_completion_function): Set list index to be 0 if
- creating a list with just one element.
+ * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
+ more parameters than it used to.
- * main.c (complete_on_cmdlist): Don't allow things with
- abbrev_flag set to be completion values.
- (symbol_completion_function): Don't accept an exact match if the
- abbrev flag is set.
+ * findvar.c (registers): Increase slop to 256 bytes, which should
+ protect us against even most RISC machines with large register
+ sets.
+ (locate_var_value): Move declaration inside related ifdef.
+
+ * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
+ throughout, to avoid throwing away buffered input from the board.
+ (nindy_wait): Supply_register takes addr_of_value, not value.
+ (i960_print_fault): Renamed from i80960_fault.
+ (nindy_fetch_registers): Avoid have_regs stuff, just get them.
+ (nindy_store_registers): Avoid regs_changed stuff, just stuff
+ them.
+ (nindy_create_inferior): Don't bother to write PC_REGNUM since
+ we can set the PC in the call to proceed(). Unpush nindy_ops
+ before pushing it on top, to avoid message to user. Eliminate
+ commentary from Unix machines that just misleads here.
+ (reset_command): Fix error message to suggest target command.
+
+Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
+
+ Release 3.92.5 as frozen.
+
+ Stabilize the merged release...with help from lint, Saber C,
+ gcc -W, etc.
+
+ Everywhere: Add include files needed to declare return types
+ of functions called.
+
+ * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
+
+ * breakpoint.h: Add undeclared breakpoint functions, and some
+ functions for display handling since I couldn't think of a better
+ .h to put them in.
+
+ * breakpoint.c (insert_breakpoints): Make code for disabling
+ shared library bkpts more likely to work. It's used when we
+ rerun a program and stop before the shared library has been
+ mapped in.
+ (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
+ cast from pointer, so it squeezes through catch_errors.
+ (bpstat_stop_status): Fix logic broken some time ago. We now
+ always create a bpstat if the stop address matches a breakpoint,
+ even if we don't stop there -- just like the old code used to do
+ before I got my fingers into it (sigh).
+ (breakpoint_1): Print "ignore count" after "stop only if"
+ condition, since that's how it actually works.
+ (mention): Handle watchpoints as well as breakpoints.
+ (watch_command): use set_raw_breakpoint and mention to do most
+ of the work (and initialize all the fields!). Only pass one
+ arg to parse_c_expression, since that's all it takes.
+
+ * command.c (not_just_help_class_command): Rename arg to args
+ since we ignore "unused argument" warnings on vars named "args".
+ inflow.c (child_terminal_info): ditto.
+ infptrace.c (kill_inferior): ditto
+ main.c (catch_errors, version_info, quit_command, pwd_command,
+ source_command, dump_me_command, editing_info,
+ set_history_size_command, set_history, show_history,
+ set_verbose): ditto
+ stack.c (locals_info): ditto
+ target.c (target_files_info): ditto
+ valprint.c (set_input_radix, set_output_radix): ditto
+
+ * core.c: Remove old variables for handling core and exec file
+ sections (data_start, data_end, stack_start, stack_end,
+ reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
+ text_end, exec_data_start, exec_data_end, text_offset,
+ exec_data_offset, data_offset, stack_offset). They're
+ superseded the more general build_section_table and
+ xfer_memory.
+ (get_exec_file): Mention the `file' command.
+ (read_memory_check): Rename to memory_error, and only call it
+ in the case of an actual error.
+ (read_memory, write_memory): call memory_error.
+ (core_fetch_registers): Register section name is ".reg".
+
+ coredep.c: Remove a bunch of crud now that all this file does
+ is pull the registers out of a core file.
+ (fetch_core_registers): Rewrite to actually work, I hope.
+
+ dbxread.c: Use a.out.gnu.h, not system a.out, now.
+ Replace index() with strchr(). Remove all the pre-BFD macro
+ definitions for accessing the symbol file.
+ (struct dbx_symfile_info): Encapsulate the information that
+ dbx_symfile_init needs to pass to dbx_symfile_read in this
+ struct.
+
+ (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
+ dbx_symfile_discard): Rearrange symbol file reading to divide
+ the format-specific part from the format-independent part,
+ leaving the format-independent part such as file name expansion
+ and opening in symtab.c. This replaces
+ partial_symbol_file_open and partial_symbol_file_read.
+ Symbol_file_read, add_file, add_file_target_command,
+ add_file_addr_command move to symtab.c. Pass an explicit
+ "mainline" flag for when reading the main symbol table, rather
+ than relying on the offset address to be zero or nonzero.
+
+ (dbx_symfile_read): Don't allow void *'s to be printed as
+ typedefs.
+ (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
+ (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
+ macro" debug version really work.
+ (read_dbx_symtab): Remove unref'd parameter inclink.
+ Avoid swapping N_SLINE symbols, for speed.
+ Merge N_TEXT!N_EXT case with the other external symbol
+ definitions' case. Add comments.
+ (start_psymtab): Allocate the symfile name in the psymtab on
+ the psymbol_obstack, rather than using the caller's storage.
+ (end_psymtab): Only allocate a dependencies list if there are
+ more than zero.
+ (psymtab_to_symtab_2): Use BFD when reopening file to read
+ its symbols for real.
+ (read_struct_type): Add FIXME comments where it needs work
+ for C++ bogosity.
+ (read_huge_number): Add FIXME about overflows.
+ (read_range_type): Add FIXME about comparing a long to 1<<32.
+
+ * coffread.c: Minor changes to move things closer to the new
+ regime with symtab.c and dbxread.c Major work is still needed
+ here.
+
+ * exec.c (exec_file_command): Remove old variables (see core.c
+ above).
+ (xfer_memory): If memory transfer is right at the end of a
+ section, don't lose.
+
+ * findvar.c (get_saved_register): If value is in a real
+ register, LVAL is lval_register, not lval_memory.
+
+ frame.h: Declare print_sel_frame and record_selected_frame.
+
+ gdb-int.texinfo: New file, for GDB internals documentation.
+ Very simple, unformatted doc of cleanups is there for now.
+
+ gdbcore.h: Remove obsolete variables that described a.out
+ section addresses and offsets. (See core.c above.)
+ Declare fetch_core_registers and registers_fetched.
+
+ getopt.c: Declare char *alloca(); even on SPARC.
+
+ infcmd.c (run_command): Call target_kill rather than
+ kill_inferior.
+ (step_command, next_command, stepi_command, nexti_command):
+ Declare from_tty parameter even though we don't use it.
+ (run_stack_dummy): argument BUFFER is a char array, not
+ a pointer to REGISTER_TYPE.
+ (finish_command): using_struct_return needed a value *,
+ not a struct symbol *.
+
+ * infptrace.c (child_xfer_memory): To avoid dependency on
+ where sections are in memory, try PT_WRITE_D and if that fails,
+ try PT_WRITE_I. Most Unixes don't care which you use.
+
+ * infrun.c (step_resume_break_shadow): Change to array to
+ match other breakpoint shadow storage.
+ (clear_proceed_status): Pass address of bpstat to
+ bpstat_clear, not the bpstat itself.
+ (child_create_inferior): FIXME comment about if the child
+ exits.
+ (start_inferior): Remove old function.
+ (child_open): Use target_kill rather than kill_inferior.
+ (wait_for_inferior): Ditto.
+ (insert_step_breakpoint, remote_step_breakpoint): Use
+ new step_resume_break_shadow.
+
+ * inftarg.c (child_wait): If all child processes die,
+ pretend that the one being waited for exited with signal 42.
+
+ * main.c (command_line_input): When scanning for comments,
+ don't coredump on unclosed quotes.
+ (quit_command): Use target_kill rther than kill_inferior.
+ (_initialize_main): Rename class_user from "user" to
+ "user-defined".
+
+ * printcmd.c (print_command_1): Initialize "fmt" if no format
+ is specified by the user.
+ (print_frame_args): Only add to args_printed if we are
+ actually fetching args from the stack (avoiding undefined
+ arg_size).
+ (_initialize_printcmd): Remove bogus \{ from string.
+
+ * remote-eb.c (eb_open): Avoid coredump on no argument.
+
+ * remote-nindy.c: Bring out of Intel environment into new
+ target environment. Remove all conditional compilation on
+ I80960. Massive hacking throughout.
+ (nindy_xfer_inferior_memory): New routine stolen from
+ infptrace.c.
+ (nindy_create_inferior): New routine pieced together, probably
+ not quite working yet.
+ (nindy_ops): New target_ops struct for nindy.
+
+ * remote-vx.c: Use write_memory rather than target_write_memory
+ to get error checking.
+ (vx_add_file_command, vx_open): Use symbol_file_add rather than
+ add_file.
+ (vx_create_inferior): Use target_terminal_ours...
+
+ * signame.c (_initialize_signame): Always initialize, since
+ we need the table for things other than psignal.
+
+ * solib.c (solib_add): Use symbol_file_add, not add_file.
+ (solib_address): Return boolean result rather than struct
+ pointer which nobody else knows the type of.
- * dbxread.c (read_type): Fixed typo in comparision to check if
- type number existed.
+ * sparc-tdep.c, valops.c: Use write_memory rather than
+ target_write_memory, to get error checking.
- * dbxread.c (read_type): Made sure to only call dbx_lookup_type on
- typenums if typenums were not -1.
+ * stack.c (locals_info, catch_info, args_info,
+ get_selected_block, frame_command, up_command): Use
+ target_has_stack, rather than have_inferior_p or
+ have_core_file_p.
-Mon Apr 24 17:52:12 1989 Randall Smith (randy at apple-gunkies.ai.mit.edu)
+ * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
- * symtab.c: Added strings.h as an include file.
+ * symfile.h: New file, defining the interface between the
+ generic and object-file-specific symbol reading code.
-Fri Apr 21 15:28:38 1989 Randall Smith (randy at apple-gunkies.ai.mit.edu)
+ * symtab.c: Move generic symbol-reading interface to symtab.c,
+ from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
+ table to map BFD targets to symbol-reading modules in GDB.
+ Change index to strchr.
+ (lookup_struct_elt_type): Use error() rather than hand-made
+ simulations thereof.
+ (lookup_partial_symbol): Speedup slightly when length == 0.
+ (symbol_file_add): New function.
+ (symbol_file_command): Call it.
+ (symfile_open, symfile_init): New function.
+ (add_file_target_command, add_file_addr_command): moved from
+ dbxread.c.
- * symtab.c (lookup_partial_symtab): Changed to only return a match
- if the name match is exact (which is what I want in all cases in
- which this is currently used.
+ * target.c (target_command): use target_kill.
+
+ * target.h (target_files_info): Don't declare, never called
+ from outside.
-Thu Apr 20 11:12:34 1989 Randall Smith (randy at gluteus.ai.mit.edu)
+ * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
+ files to determine stack end address.
+
+ * valarith.c (value_x_binop, value_x_unop): Change error message
+ to be more useful. Pass proper argument to value_struct_elt.
+
+ * valops.c (value_assign): FIXME comment that long long
+ bitfields will break here.
+
+ * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
+ Update `make saber_gdb' to work better.
+
+ * TODO: A woman's work is never done.
+
+ * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
+ main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
+ remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
+ sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
+ target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
+ valops.c, valprint.c, exec.c: Lint.
+
+
+Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
+
+ Continuing Intel 960 port merge of GDB.
+
+ * Makefile.dist: Merge i960 "nindy-share" files. Rename
+ malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
+ Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
+ Wack over "make depend" so it handles files in subdirectories
+ vx-share, nindy-share, bfd, and in the current directory.
+
+ * blockframe.c (get_prev_frame_info): Remove fatal error
+ if stack not defined.
+
+ * core.c (core_open, core_detach): New functions that handle
+ the old "core-file" command as "target core" and "detach" instead.
+ (core_file_command): Call them.
+ (core_xfer_memory): Use common routine xfer_memory.
+
+ * dbxread.c: Include a.out.gnu.h, not system a.out.h.
+ dbxread now uses bfd for everything but symbol reading itself.
+ BFD internals are used to drag out the relevant file offsets.
+ (partial_symbol_file_open): Change args all around for BFD.
+
+ * symtab.c: Rename "value" to "val" everywhere, so we can
+ #include "value.h".
+ (symbol_file_command): New command, moved from dbxread.c
+ and coffread.c. It uses BFD to read the file, then vectors
+ based on its type, to dbx or coff symbol readers.
+ * symtab.h: Extern a few vars for symbol_file_command.
+
+ * target.h: Breakpoint takes a char * save area, not a char **.
+
+ * valprint.c (val_print): When unpacking bitfields, offset
+ the address in gdb of the value, if it is declared with a shorter
+ type. Remove the last "runtime kludge test" of host byte order.
+
+ * utils.c: Remove old my_bfd_read routine.
+
+ * stack.c (frame_info): Use target_has_stack. Print program counter
+ register's actual name rather than "pc", since it's called the
+ "ip" (instruction pointer) on the i960 (sigh).
+
+ * target.c (target_command): Add command for selecting a target
+ type and calling its open routine. This is used for initiating
+ communication with a particular target, in a generic way.
- * m-isi.h [REGISTER_U_ADDR]: Installed new version from net.
- * default-dep.c: Deleted inclusion of fcntl.h; apparently not
- necessary.
- * Makefile: Added comment about compiling on isi under 4.3.
+ * tm-i960.h: Update for modern gdb. Remove semicolons from
+ various macros. Handle reading struct return convention, and
+ error-out attempts to return structs with the "return" command.
+ Be sure gdb doesn't think we know how to call functions in the
+ inferior.
+
+ * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
+ to i960_xxx in lower case.
+ (arg_address): Circumvent errors due to LOC_ARG_BLOCK
+ not being defined yet.
- * breakpoint.c (break_command_1): Only give decode_line_1 the
- default_breakpoint_defaults if there's nothing better (ie. make
- the default be off of the current_source notes if at all
- possible).
+ * remote.c (remote_open): Call start_remote to initialize
+ wait_for_inferior during open.
+ (remote_xfer_inferior_memory): Return length written rather
+ than errno value.
+
+ * remote-vx.c (target_command -> vx_open): Use new generic
+ target command.
+ * remote-eb.c, inftarg.c, exec.c: ditto.
- * blockframe.c (get_prev_frame_info): Clean up comments and
- delete code ifdefed out around FRAMELESS_FUNCTION_INVOCATION test.
+ * infrun.c: Fix comments.
+ (attach_program -> child_open): Use new generic target command.
+ (wait_for_inferior): Clear saved register values before target_wait,
+ so target_wait can set some of them if convenient.
- * remote.c: Added a "?" message to protocol.
- (remote_open): Used at startup.
- (putpkt): Read whatever garbage comes over the line until we see a
- '+' (ie. don't treat garbage as a timeout).
+ * infptrace.c (fetch_inferior_registers, store_inferior_registers):
+ Return success indicator, not void.
+ (child_xfer_memory): Avoid fetching initial word if we'll
+ overwrite it anyway.
- * valops.c (call_function): Eliminated no longer appropriate
+ * infcmd.c (attach_command): Use new generic target open routine.
+ (_initialize_infcmd): Update doc on attach and detach commands.
+ (do_registers_info): Merge in a byte-order problem as a FIXME
comment.
- * infrun.c (wait_for_inferior): Changed several convex conditional
- compilations to be conditional on CANNOT_EXECUTE_STACK.
-

- LOC_REF_ARG.
- * valarith.c (value_subscripted_rvalue): Created.
- (value_subscript): Used above when app.
- (value_less, value_equal): Change to cast to (char *) before doing
- comparison, for machines where that casting does something.
- * valops.c (call_function): Setup to deal with machines where you
- cannot execute code on the stack segment.
- * valprint.c (val_print): Make sure that array element size isn't
- zero before printing. Set address of default array to address of
- first element. Put in a couple of int cast. Removed some convex
- specific code. Added check for endianness of machine in case of a
- packed structure. Added code for printing typeless integers and
- for LONG LONG's.
- (set_maximum_command): Change to use parse_and_eval_address to get
- argument (so can use expressions there).
- * values.c (value_of_internalvar, set_internalvar_component,
- set_internalvar, convenience_info): Add in hooks for trapped
- internal vars.
- (unpack_long): Deal with LONG_LONG.
- (value_field): Remove LONGEST cast.
- (using_struct_return): Fixed typo ENUM ==> UNION.
- * xgdb.c (_initialize_xgdb): Make sure that specify_exec_file_hook

- * m-sun4os4.h (STACK_END_ADDRESS): Changed it to 0xf8000000 under
- os 4.0.
-
-Sat Apr 8 17:04:07 1989 Randall Smith (randy at apple-gunkies.ai.mit.edu)
-
- * dbxread.c (process_one_symbol): In the case N_FUN or N_FNAME the
- value being refered to is sometimes just a text segment variable.
- Catch this case.
-
- * infrun.c (wait_for_inferior), breakpoint.c
- (breakpoint_stop_status): Move the selection of the frame to
- inside breakpoint_stop_status so that the frame only gets selected
- (and the symbols potentially read in) if the symbols are needed.
-
- * symtab.c (find_pc_psymbol): Fixed minor misthough (pc >=
- fucntion start, not >).
-
- * breakpoint.c (_initialize_breakpoint): Change "delete" internal
- help entry to simply refer to it being a prefix command (since the
- list of subcommands is right there on a "help delete").
-
-Fri Apr 7 15:22:18 1989 Randall Smith (randy at apple-gunkies.ai.mit.edu)
-
- * blockframe.c (find_pc_partial_function): Created; figures out
- what function pc is in (name and address) without reading in any
- new symbols.
- * symtab.h: Added decl for above.
- * infrun.c (wait_for_inferior): Used instead of
- find_pc_function_start.

- thing.
-
- * dbxread.c (psymtab_to_symtab): No longer patch readin pst's out
- of the partial_symtab_list; need them there for some checks.
- * blockframe.c (block_for_pc), source.c (select_source_symtab),
- symtab.c (lookup_symbol, find_pc_symtab, list_symbols): Made extra
- sure not to call psymtab_to_symtab with ->readin == 1, since these
- psymtab now stay on the list.
- * symtab.c (sources_info): Now distinguishes between psymtabs with
- readin set and those with it not set.
-
- * symtab.c (lookup_symtab): Added check through partial symtabs
- for name with .c appended.

- to select_source_symtab to match new conventions.
-
- * dbxread.c (add_file_command): This command no longer selects a
- symbol table to list from.
-
- * infrun.c (wait_for_inferior): Only call find_pc_function (to
- find out if we have debugging symbols for a function and hence if
- we should step over or into it) if we are doing a "step".

-
- * main.c (command_line_input): Added a local buffer and only
- copied information into the global main.c buffer when it is
- appropriate for it to be saved (and repeated).
- (dont_repeat): Only nail line when we are reading from stdin
- (otherwise null lines won't repeat and what's in line needs to be
- saved).
- (read_command_lines): Fixed typo; you don't what to repeat when
- reading command lines from the input stream unless it's standard
- input.
-
- * inflow.c: Removed inclusion of sys/user.h; no longer necessary.
- (, terminal_init_inferior, terminal_inferior, terminal_ours_1,
- term_status_command, _initialize_inflow) Seperated out declaration
- and usage of terminal mode structures based on the existence of
- the individual ioctls.
- * utils.c (request_quit): Restore signal handler under USG. If
- running under USG initialize sys_siglist at run time (too much
- variation between systems).
-

- a.out.h.
- (store_inferior_registers): Fixed error message.
- (core_file_command): Improved error messages from reading in of
- u area in core file. Changed calculation of offset of registers
- to account for some machines putting it in as an offset rather

- registers from core file.
-
- * coffread.c (read_file_hdr): Added final check for BADMAG macro
- to use if couldn't recognize magic number.
- * Makefile: Added explicit directions for alloca addition.
- Included alloca.c in list of possible library files. Cleaned up
- possible library usage. Included additional information on gcc
- and include files.
-
- * source.c, remote.c, inflow.c, dbxread.c, core.c, coffread.c:
- Changed include of sys/fcntl.h to an include of fcntl.h (as per
- posix; presumably this will break fewer machines. I hopw).
- * README: Added a pointer to comments at top of Makefile.
- * Makefile: Added a comment about machines which need fcntl.h in
- sys.
-
-Tue Apr 4 11:29:04 1989 Randall Smith (randy at apple-gunkies.ai.mit.edu)

- above needed it.
-
- * main.c (,set_verbose_command, initialize_main): Created a
- variable "info_verbose" which says to talk it up in various and
- sundry places. Added command to set this variable.

-
- * dbxread.c (define_symbol): Made an "i" constant be of class

-
- * README: Made a note about modifications which may be necessary
- to the manual for this version of gdb.
-
- * blockframe.c (get_prev_frame_info): Now we get saved address and
- check for validity before we check for leafism. This means that
- we will catch the fact that we are in start, but we will miss any
- fns that start calls without an fp. This should be fine.
-
- * m-*.h (FRAME_CHAIN): Modified to return 0 if we are in start.
- This is usually a test for within the first object file.
- * m-sparc.h (FRAME_CHAIN): The test here is simply if the fp saved
- off the the start sp is 0.
-
- * blockframe.c (get_prev_frame_info): Removed check to see if we
- were in start. Screws up sparc.
-
- * m-sparc.h (FRAME_FIND_SAVED_REGISTERS): Changed test for dummy

-
- * gdb.texinfo: Added section on frameless invocations of functions
- and when gdb can and can't deal with this.
-
- * stack.c (frame_info): Disallowed call if no inferior or core
- file; fails gracefully if truely bad stack specfication has been
- given (ie. parse_frame_specification returns 0).
+ * findvar.c (find_saved_register): Avoid problem in current frame.
+ (read_relative_register): Ditto.
+ (write_register): Convert byte order on the way out.

+ symbol_file_command): Pass from_tty arg to hush 'em up.
- * dbxread.c (symbol_file_command): Use malloc to allocate the
- space for the string table in symbol_file_command (and setup a
- cleanup for this). This allows a more graceful error failure if
- there isn't any memory availible (and probably allows more memory
- to be avail, depending on the machine).
+ * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
+ Add magic numbers for 960 COFF format.
- Additional mods for handling GNU C++ (from Tiemann):
- * dbxread.c (read_type): Added case for '#' type (method type, I
- believe).
- (read_struct_type): If type code is undefined, make the main
- variant for the type be itself. Allow recognition of bad format
- in reading of structure fields.
- * eval.c (evaluate_subexp): Modify evaluation of a member of a
- structure and pointer to same to make sure that the syntax is
- being used correctly and that the member is being accessed correctly.
- * symseg.h: Added TYPE_CODE_METHOD to enum type_code. Add a
- pointer to an array of argument types to the type structure.
- * symtab.c (lookout_method_type, smash_to_method_type): Created.
- * symtab.h (TYPE_ARG_TYPES): Created.
- * valops.c (call_function): Modified handling of methods to be the
- same as handling of functions; no longer check for members.

- are the innermost frame, and 2) return the next frame in's value
- if the SP is being looked for.
+ CHANGE_LOG entries from their port, which was based on
+ gdb+-2.8.0:
- * blockframe.c (get_next_frame): Created; returns the next (inner)

+ After opening remote tty, wait for 1 second to go by without input
+ from it before trying to talk to NINDY (fixes problems with the
+ Heurikon HK80/V960E).
- * symtab.c (make_symbol_completion_list): Completely rewrote to
- never call psymtab_to_symtab, to do a correct search (no
- duplicates) through the visible symbols, and to include structure
- and union fields in the things that it can match.
+ Mon Apr 4 16:33:05 PDT 1990
+ Some output was not being suppressed in 'batch' mode.

- * infrun.c: Fixed up inclusion of aouthdr.h on UMAX_PTRACE.
+ Make sure to zero low-order bits in rip's because of bug in 960CA

+Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
+
+ Massive changes to wall off the remote-debugging interface
+ behind a function vector. The port to handle VxWorks targets
+ is also part of this.
+
+ All files: Replace references to renamed functions,
+ remove references to remote_debugging, remove references to
+ have_include_file, have_core_file in favor of target_has_stack,
+ target_has_memory, etc.
+
+ * Modularize the breakpoint interface.
+ breakpoint.h (BREAKPOINT_MAX): New define sets max length of
+ a breakpoint instruction.
+ breakpoint.c: struct breakpoint's shadow_contents now sized as
+ BREAKPOINT_MAX.
+ (insert_breakpoints): Vector to target to install breakpoints.
+ (remove_breakpoints): Vector to target here too.
+ Remove REMOTE_SA_SPARC kludges and other remote_debugging.
+ sparc-tdep.c (single_step): Use new breakpoint interface for
+ the single-step breakpoints.
+ mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
+ New file, contains routines to insert and remove breakpoints by
+ reading out the old contents and later replacing them. This is
+ how ptrace breakpoints work, and many remote systems as well.
+
+ * tm-vxworks68.h: New config file, overrides a few things for
+ Wind River's preferences.
+
+ * target.h: New file, for transfer vector used to talk to the
+ inferior (child, attached, core, exec, remote, etc). All accesses
+ to the thing being debugged should come through these vectors.
+ target.c: New file, routines to handle transfer vector.
+ (various files): Add transfer vectors XXX_ops for the various
+ targets and pseudo-targets (core files, etc) we support.
+
+ * breakpoint.c (bpstat_stop_status): Further explorations of
+ watchpoints and why things don't work all the time.
+ (bpstat_alloc): New fn to allocate a bpstat and chain it.
+
+ * config.gdb: Only add "source ${srcdir}/.gdbinit" to
+ the local gdbinit if it doesn't already have it.
+
+ * core.c (core_ops): add and install.
+ Allow core debugging without exec file.
+
+ * dbxread.c (free_and_init_header_files): Merge two fns.
+ (end_symtab): Free named symbol table when a new version comes in.
+ (read_dbx_symtab): Relocate all kinds of symbols with base
+ address. First step toward handling different text, data, bss
+ reloc.
+ (add_file_addr_command): Renamed add_file_command.
+ (add_file_command): Vector to remote handler.
+ Add "load" as an alias for "add-file" command.
+
+ * defs.h: Allow "volatile" to be used in non-ANSI; use it for
+ non-returning functions.
-Fri Mar 10 17:22:31 1989 Randall Smith (randy at apple-gunkies.ai.mit.edu)
+ * exec.c: Add exec_ops, and push it as a target when an exec
+ file is specified.
+
+ * infcmd.c (run_command): Pass executable file name and arg list
+ separately when starting an inferior. Permit "run" when no exec
+ file is specified, for VxWorks.
+ (detach_command): Move to child_detach in inftarg.c.
+
+ * inftarg.c: New file. Unix-child-specific routines, and the
+ child_ops structure.
+
+ * inferior.h (registers): Export "registers" as the way for
+ target dependent register handlers to find gdb's local copy of
+ the registers. Rename "stop_after_attach" to "stop_soon_quietly"
+ since it is now used by places that want wait_for_inferior to
+ handle the grunge but want to see every trap from the inferior.
+
+ * inflow.c (create_inferior): Pull out, and merge into infrun.c.
+ Eliminate remote_debugging hooks in terminal handling.
- * main.c (command_line_input): Checked for -1 return from
- readline; indicates EOF.
+ * infrun.c: Replace start_inferior with child_create_inferior.
+ Move all the hair of Unix shells and ptrace idiosyncracies into
+ child_create_inferior, so remote handlers don't have to deal.
+ Remove running_in_shell. Rename stop_after_attach to
+ stop_soon_quietly, and use it in a few other places where we want
+ to just call wait_for_inferior and get control back on the first
+ trap. trap_expected now never takes a value > 1.
+ (init_wait_for_inferior): Initialize static vars when a new
+ process is created.
+
+ main.c (gdbinit): Add new hook for .gdbinit file name, let
+ it be overridden by config files as GDBINIT_FILENAME.
+ (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
+ Both of these are used for VxWorks gdb.
+
+ mcheck.c: rename include file "gmalloc.c" to avoid problems
+ with system include file "malloc.c".
+
+ param-no-tm.h: New include file, same as param.h but does not
+ include the default "tm.h" file. This is used in files where
+ the target is known, e.g. remote-eb.c or sparc-xdep.c.
+
+ param.h: Now just a shell that includes tm.h and param-no-tm.h.
+
+ remote-vx.c: New file, VxWorks remote debugging support. Uses
+ RPC routines that are shared with the target system, in directory
+ ${srcdir}/vx-share.
+
+ remote.c: Vectorize remote interface.
+
+ source.c: Globalize source_path, and make an alias "l" for "list"
+ since we now have the "load" command.
+
+ sparc-xdep.c: Use new param-no-tm.h.
+
+ symmisc.c (free_named_symtab): Add new function from Wind River.
+ However, ifdef it out for now while we think about what it should
+ really be doing.
+
+ tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
+ PREPARE_TO_STORE to
+ the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since

-Fri Mar 3 00:31:27 1989 Randall Smith (randy at gluteus.ai.mit.edu)
+ Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
+ source and target lists. Add vx-share to default list of include
+ directories. Add new files to src and target lists: mem-break,

+ ${srcdir} versions of munch and createtags are used.
- * remote.c (remote_open): Cast return from signal to (void (*)) to
- avoid problems on machines where the return type of signal is (int
- (*)).

+ compiler fits, simplify it.
+
+ * gdb.texinfo (directory command): Doc new dir command.
+ source.c (directory_command): "dir" now puts things on the front
+ of the path, moves dups up front, and handles multiple names
+ on the command line, inserting each one in order. It also
+ blows away cached line and full_filename info.
+
+ * stack.c (backtrace_command): Skip "more stack frames follow"
+ unless interactive.
+
+ * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in

+ xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
+ The only odd one was Gould NP1, which had defined vprintf to

+ * tm-sparc.h: define DO_DEFERRED_STORES.
+
+ * sparc-xdep.c (store_inferior_registers): when storing float
+ registers, don't store stack regs too. When storing the SP,
+ however, DO store the stack regs too. This fixes a bug in which
+ the dummy frame is not recognized when a call_function finishes,
+ because its frame pointer (in the stack regs) was never
+ initialized.
+ (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
+ even though we don't know how to read them from an inferior.
+ valops.c (call_function): Comment about storing SP.
+
+ * infrun.c (save_inferior_status): Save away the original bpstat
+ chain so it can be restored later. Install the copied version for
+ use by whoever saved the status. It will be blow away by
+ restore_inferior_status, and the original chain restored. This is
+ important for people who have pointers into the original.
+
+ * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,

+ we allocate one.
+ symtab.c (B_CLRALL): define.
+
+ * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
+ using == rather than =. Huh... This fixes the dreaded problem
+ wherein builtin_type_int becomes TYPE_CODE_FLT.
+
+ * core.c (info_files): Show the inferior pid.
+
+ * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
+ already knows how to look in the source directory.

+ compilation fields.
+ stack.c (backtrace_command): Avoid pre-pass to read symbols, if
+ verbose is not set.
+ (print_frame_info): Avoid special-casing symbols that have not yet
+ been read in.
- * Makefile: Added new variable READLINE_FLAGS so that I could
- force compilation of readline.c and history.c with -DSYSV on
- system V machines. Mentioned in Makefile comments at top.
+ * source.c (open_source_file): Quick path if we have already
+ located the source file by its full name.
+
+ * symtab.c (lookup_symbol): Use find_pc_symtab rather than
+ find_pc_psymtab. When a name is found in the misc function
+ vector, search the symbol table for its mangled name, not the
+ name that the user typed.
+
+ * bfd.h: Fix missing comment terminators, make #endifs match.
+
+ * valarith.c (value_less): Handle unsigned int comparisons.
+ Add FIXME about pointer compares, which assume host and target

+ (quit_command): Avoid clobbering exec_bfd while quitting.
+
+ * Initial BFD (binary file diddling library) merger:
+ coffread.c: Change AOUTHDR to struct exe_hdr.
+ dbxread.c: ditto.
+ core.c: initialize initialized data at compile time.

+ * expread.y: lint
+ * valarith.c: lint
+
+ * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
+
+ * sparc-tdep.c (isannulled): Take instruction as parameter, don't
+ read it from memory. This will allow us to save ptrace calls
+ eventually. Changed caller single_step too.
- * utils.c (fprintf_filtered): Removed printing of "\\\n" after
- printing linesize - 1 chars; assume that the screen display will
- take care of that. Still watching that overflow.
+ * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
+ that we aren't going to use, saving many ptrace calls, especially
+ when watchpointing or single stepping. Use some #define's for
+ constants.
+ (store_inferior_registers): Ditto.
+ (core_file_command): Use some #define's for constants.
- * main.c: Created the global variables linesize and pagesize to
- describe the number of chars per line and lines per page.
+ * tm-sparc.h: Add #define's for some register numbers, so we
+ can eliminate the use of random constants in sparc-xdep.c.
-Thu Feb 16 17:27:43 1989 Randall Smith (randy at gluteus.ai.mit.edu)
+ * stack.c (frame_command, print_frame_info, up_command,
+ down_command) Remove frame_changed, since it
+ causes a bug and doesn't seem to do anything useful. In some
+ places it was used as a flag, in others as a stack level (?).
- * printcmd.c (do_examine, print_scalar_formatted, print_address,
- whatis_command, do_one_display, ptype_command), valprint.c
- (value_print, val_print, type_print_method_args, type_print_1,

- (backtrace_command, print_frame_info), symtab.c (list_symbols,
- output_source_filename), command.c (help_cmd, help_list,
- help_command_list): Replaced calls to printf, fprintf, and putc
- with calls to [f]printf_filtered to handle more processing.
- Killed local more emulations where I noticed them.
+ * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
+ default is to use the portable (vprintf) version rather than the
+ kludge version.
+ * xm-news.h (MISSING_VPRINTF): Add.
-Wed Feb 15 15:27:36 1989 Randall Smith (randy at gluteus.ai.mit.edu)
+ * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
- * defs.h, utils.c (initialize_more_filter, fprintf_filtered,
- printf_filtered): Created a printf that will also act as a more
- filter, prompting the user for a <return> whenever the page length
- is overflowed.
+Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
- * symtab.c (list_symbols): Elminated some code inside of an #if 0.
+ * Remove stuff that forces -Bstatic linking of gdb, and warnings
+ about linking debugged programs -Bstatic in the sun?os4 config
+ files in tconfig and xconfig subdirectories.
-Tue Feb 14 11:11:24 1989 Randall Smith (randy at gluteus.ai.mit.edu)
+ * main.c (main): Remove unreached exit(0) now that we exit
+ via quit_command().
- * Makefile: Turned off backup versions for this file; it changes
- too often.
+ * Create TODO file for online bug list. There are too many
+ "little" bugs to keep track of on paper.
- * command.c (lookup_cmd, _initialize_command): Changed '!' so that
- it was no longer a shell escape. "sh" must be used.
+ rather than kingdon@ai.
- * main.c (command_line_input, set_history_expansion,
- initialize_main): Turned history expansion on, made it the
- default, and only execute it if the first character in the line is
- a '!'.
+Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
- * version.c, gdb.texinfo: Moved version to 3.2 (as usual, jumping
- the gun some time before release).
+ * Makefile.dist (VERSION): 3.91.4 now.
- * gdb.texinfo: Added sections (adapted from Brian's notes) on
- command line editing and history expansion.
+ * symtab.c (init_misc_bunches): Rename from init_misc_functions.
+ (condense_misc_bunches): Add sanity check that misc_count is
+ the same as the number of symbols in the bunch.
+
+ * coffread.c: rename init_misc_bunches. Pass an argument
+ to condense_misc_bunches (a zero).
+
+ * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
+ every time we are called; don't rely on our caller to do it.
+ (add_file): Remove call to init_misc_bunches.
+
+ * mipsread.c: Only warn, don't error, if unknown symbol types.
+ This keeps an old gdb from falling on its face if it sees newly
+ extended symbol info. Rename init_misc_bunches.
+
+Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
+
+ * Merge in changes from Per Bothner for DECstations and other
+ MIPS stuff. The rest is Bothner speaking:
+
+ The next message is a merger of Alessando Forin's mips port with
+ mine. I've tried to use my good if biased judgment to get
+ the best of both. It *does* need testing.
+
+ Some of the changes are general, *not* mips-specific.
+
+ param.h:
+ Didn't believe in little-endian bit order.
+ There are still inconsistencies about whether flags
+ like BITS_BIG_ENDIAN are integer (#if ...) or
+ boolean (#ifdef ...). I tried to paper over them.
+
+ dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
+ Moved some misc_function code that was common to
+ {dbx,coff,mips}read.c to symtab.c.
+ In the process, I think I cleaned things up a bit.
+ At the same time, moved obsavestring and obconcat to symtab.c.
+
+ dbxread.c:
+ Removed obsolete condense_addl_misc_bunches (use
+ condense_misc_bunches(1) instead).
+
+ exec.c:
+ Needed to include <sys/dir>, at least on DECstations.
+
+ valops.c, mips-tdep.c, tm-mips.h:
+ Added PUSH_ARGUMENTS macro to support funny argument-pushing
+ conventions (when STACK_ALIGN is insufficient).
+ Needed on mips, where doubles need 8-byte alignment,
+ but ints only need 4.
+
+ mips-opcode.h:
+ Removed cruft that was not being used.
+
+ mips-pinsn.c:
+ Print $ before register-names (I think that makes things a little
+ more consistent).
+ Never print two instructions, even if one delays.
+ Removed hex-disassemble set_cmd. (This is not mips-specific,
+ so I think the argument is whether it is generally worthwhile or not.
+ I'm inclined to think not, given how easy it is to
+ convert between radixes in gdb.)
+
+ mipsread.c:
+ This is basically Alessando's code.
+ It doesn't use obstacks; I changed it to use obstacks
+ in a few minor places where using malloc causes a
+ memory leak. (Probably, more places could/should be changed.)
+ I added record_misc_function where it was missing.
+ In symbol_file_command and add_file_command, I tried
+ to make the code consistent with more recent versions.
+ Minor sylistic changes in parse_procedure.
+ Make a .gdbinfo. psuedo-symbol point back to the real
+ procedure symbol (using the isym field).
+
+ mips-tdep.c:
+ This is basically from my port, but with a lot of details
+ and a number of routines merged in from Alessando's version.
+ I basically used my code "raw" backtrace (use heuristics
+ from the actual code, rather than symbol table info) - though
+ the idea is Alessandro's. I feel my code is a little cleaner
+ here, particularly in being a little more flexible, such as being
+ able to handle gcc-produced code (which it now can).
+ It also doesn't do frame caching (which is not useful
+ more recent gdb versions).
+ I also used my code for push_/pop_dummy, more or less.
+ I tried to incorporate AF's code for testing sigtramp
+ while backtracing; I probably got it wrong.
+ Added mips_print_register, which tries to scrunch as much
+ information as possible on a screen...
+ Removed the skip-prologue set_cmd. As with hex-disassemble (see
+ under mips-pinsn.c), I don't see anything mips-specific here,
+ and I don't see it being all that useful anyway.
+
+ tm-mips.h:
+ Added a $fp psuedo-reg distinct from $fp (nice for gcc).
+ Use more register names (rather than hard-cases numbers).
+
+Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
- * main.c (set_command_editing, initialize_main): Modified name to
- set_editing and modified command to "set editing".
+ * Hack up 3.90.11 changes:
- * Makefile: Put in dependencies for READLINEOBJS.
+ * Makefile.dist (depend): parameterize $(GCC).
+ Add solib.c and solib.o.
+ (readline): Fix vpath for both absolute or relative SRCDIR.
- * main.c (history_info, command_info): Combined into new command
- info; deleted history_info.
- (initialize_main): Deleted "info history" command; it was
- interfering with the value history.
+ Also, let the part I didn't understand at least compile so
+ I can test the rest. FIXME.
- * coffread.c (enter_linenos): Modified to do bit copy instead of
- pointer dereference, since the clipper machine can't handle having
- longs on short boundaries.
- (read_file_hdr): Added code to get number of syms for clipper.
-
- * stack.c (return_command): Fixed method for checking when all of
- the necessary frames had been popped.
+ * dbxread.c: Fix thinko using strcmp.
+ (init_psymbol_list): declare static.
+ (partial_symbol_file_open): Comment cleanups better, avoid
+ cleaning up the string table since the caller will do that.
+ Move the stat for mod time into symbol_file_command, temporarily.
+ (There should be a mod time for each symbol file, eventually,
+ to control its rereading. FIXME.)
- * dbxread.c (read_dbx_symtab (ADD_PSYMBOL_TO_LIST)): Fixed typo in
- allocation length.
-
-Mon Feb 13 10:03:27 1989 Randall Smith (randy at gluteus.ai.mit.edu)
+ * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
+ SunOS, which gives error for shared libs otherwise. (From
+ Schaefer, probably FIXME needs work for portability.)
- * dbxread.c (read_dbx_symtab): Split assignment to namestring into
- several different assignments (so that it wouldn't be done except
- when it had to be). Shortened switches and duplicated code to
- produce the lowest possible execution time. Commented (at top of
- switch) which code I duplicated.
-
- * dbxread.c (read_dbx_symtab): Modified which variables were
- register and deleted several variables which weren't used. Also
- eliminated 'F' choice from subswitch, broke out strcmp's, reversed
- compare on line 1986, and elminated test for !namestring[0]; it is
- caught by following test for null index of ':'.
+ * solib.c: Move #include "param.h" to work.
+ Lowercase all the Uppercase Letters In the Messages.
+ (find_solib): Clean up inferior_so_name for debug printouts.
+ Allow no argument, to mean all shared libraries.
-Sun Feb 12 12:57:56 1989 Randall Smith (randy at plantaris.ai.mit.edu)
-
- * main.c (gdb_completer_word_break_characters): Turned \~ into ~.
+ * symmisc.c: include param.h to get CLEAR_SOLIB.
-Sat Feb 11 15:39:06 1989 Randall Smith (randy at plantaris.ai.mit.edu)
+Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
- * symtab.c (find_pc_psymtab): Created; checks all psymtab's till
- it finds pc.
- (find_pc_symtab): Used; fatal error if psymtab found is readin
- (should have been caught in symtab loop).
- (lookup_symbol): Added check before scan through partial symtab
- list for symbol name to be on the misc function vector (only if in
- VAR_NAMESPACE). Also made sure that psymtab's weren't fooled with
- if they had already been read in.
- (list_symbols): Checked through misc_function_vector for matching
- names if we were looking for functions.
- (make_symbol_completion_list): Checked through
- misc_function_vector for matching names.
- * dbxread.c (read_dbx_symtab): Don't bother to do processing on
- global function types; this will be taken care of by the
- misc_function hack.
+ * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
+ to 3.90.11. ChangeLog entries below are from this.
- * symtab.h: Modified comment on misc_function structure.
+Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
-Fri Feb 10 18:09:33 1989 Randall Smith (randy at plantaris.ai.mit.edu)
+ * Version 3.90.11.
- * symseg.h, dbxread.c (read_dbx_symtab, init_psymbol_list,
- start_psymtab, end_psymtab), coffread.c (_initialize_coff),
- symtab.c (lookup_partial_symbol, list_symbols,
- make_symbol_completion_list): Changed separate variables for
- description of partial symbol allocation into a specific kind of
- structure.
+ * Makefile.dist (HFILES): Add tm-sunos.h.
- (read_dbx_symtab, process_symbol_for_psymtab): Moved most of
- process_symbol_for_psymtab up into read_dbx_symtab, moved a couple
- of symbol types down to the ingore section, streamlined (I hope)
- code some, modularized access to psymbol lists.
+Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
-Thu Feb 9 13:21:19 1989 Randall Smith (randy at apple-gunkies.ai.mit.edu)
+ * Version 3.90.10.
- * main.c (command_line_input): Made sure that it could recognize
- newlines as indications to repeat the last line.
+ * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
- * symtab.c (_initialize_symtab): Changed size of builtin_type_void
- to be 1 for compatibility with gcc.
- * main.c (initialize_main): Made history_expansion the default
- when gdb is compiled with HISTORY_EXPANSION.
+ * sparc-opcode.h Added single-operand version of rett.
- * readline.c, readline.h, history.c, history.h, general.h,
- emacs_keymap.c, vi_keymap.c, keymaps.c, funmap.c: Made all of
- these links to /gp/gnu/bash/* to keep them updated.
- * main.c (initialize_main): Made default be command editing on.
+Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
-Wed Feb 8 13:32:04 1989 & Smith (randy at hobbes)
+ * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
+ Put parens around gcc_p in expansion.
- * dbxread.c (read_dbx_symtab): Ignore N_BSLINE on first
- readthrough.
+Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
- * Makefile: Removed convex-dep.c from list of distribution files.
+ * utils.c (lines_to_list): Return 10 if lines_per_page == 0.

+Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
- * main.c: Added command lists sethistlist and unsethistlist to
- accesible command lists.
- (parse_binary_operation): Created to parse a on/1/yes vs. off/0/no
- spec.
- (set_command_edit, set_history, set_history_expansion,
- set_history_write, set_history_size, set_history_filename,
- command_info, history_info): Created to allow users to control
- various aspects of command line editing.
+ * Changes for Sun shared libraries:
+ blockframe.c (find_pc_partial_function): If a non-text symbol
+ is found, set *address = pc - FUNCTION_START_OFFSET.
+ breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
+ Disable breakpoints instead of giving an error.
+ source.c (select_source_symtab): Initialize cs_pst.
+ symmisc.c: Call CLEAR_SOLIB if defined.
+ symtab.h: Make text{low,high} CORE_ADDR not int.

+ solib.c: New file.
+ dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
+ (record_misc_function): Give correct type for N_DATA symbols.
+ (condense_misc_bunches): do "misc_function_count = j" regardless
+ of inclink.
+ Take code which is shared between symbol_file_command and
+ add_file_command and put it into partial_symbol_file_{open,read}.
+ Split add_file_command into add_file_command and add_file.
+ Make psymtab_to_symtab read in the string table if the file
+ is not symfile.
+ Two new parameters to read_dbx_symtab and start_psymtab.
+ tm-sunos.h: New file.
- * main.c (symbol_creation_function): Created.
- (command_line_input, initialize_main): Added rest of stuff
- necessary for calling bfox' command editing routines under

+ * infcmd.c: Change cont_command to continue_command and "cont"
+ to "continue".
- * main.c: Invented variables to control command editing.
- command_editing_p, history_expansion_p, history_size,
- write_history_p, history_filename. Initialized them to default
- values in initialize_main.
+Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
- * infcmd.c (registers_info), infrun.c (signals_info),
- * main.c (gdb_read_line): Changed name to command_line_input.
- (readline): Changed name to gdb_readline; added second argument
- indicating that the read value shouldn't be saved (via malloc).
- * infcmd.c (registers_info), infrun.c (signals_info), main.c
- (copying_info), symtab.c (output_source_filename, MORE,
- list_symbols): Converted to use gdb_readline in place of
- gdb_read_line.
+ * breakpoint.c (enable_breakpoint): Get value of watchpoint.
+ * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
-Sun Feb 5 17:34:38 1989 Randall Smith (randy at apple-gunkies.ai.mit.edu)
+ * values.c (USE_STRUCT_CONVENTION): Check for structures of
+ size 1,2,4,8 rather than size < 8.
- * blockframe.c (get_frame_saved_regs): Removed macro expansion
- that had accidentally been left in the code.
+ * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
+ as necessary, not just once.
-Sat Feb 4 17:54:14 1989 Randall Smith (randy at apple-gunkies.ai.mit.edu)
+ * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
- * main.c (gdb_read_line, readline): Added function readline and
- converted gdb_read_line to use it. This was a conversion to the
- line at a time style of input, in preparation for full command

+Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
-Fri Feb 3 12:39:03 1989 Randall Smith (randy at apple-gunkies.ai.mit.edu)
+ * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
- * dbxread.c (read_dbx_symtab): Call end_psymtab at the end of
- read_dbx_symtab if any psymtab still needs to be completed.
+ * tm-news.h: Add CALL_DUMMY_*.
- * config.gdb, sun3-dep.c: Brought these into accord with the
- actual sun2 status (no floating point period; sun3-dep.c unless
- has os > 3.0).
- * m-sun2os2.h: Deleted; not needed.
+ * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
- * config.gdb: Added a couple of aliases for machines in the
- script.
+ * config.gdb: In list_host, list_target, use ${i}, not $i.
- * infrun.c: Added inclusion of aouthdr.h inside of #ifdef UMAX
- because ptrace needs to know about the a.out header.
+Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
- * Makefile: Made dep.o depend on dep.c and config.status only.
+ * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
- * expread.y: Added declarations of all of the new write_exp_elt
- functions at the include section in the top.
+ * sparc-opcode.h: Change all store floating-point state register
+ instructions to have the right match & lose fields.
- * Makefile: Added a YACC definition so that people can use bison
- if they wish.
+Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
- * Makefile: Added rms' XGDB-README to the distribution.
+ * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
+ VPATH to readline.
+ config.gdb: If srcdir != ., create readline directory and
+ copy a makefile into it.
- * Makefile: Added removal of init.o on a "make clean".
+ * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
+ consistency with POSIX.
-Thu Feb 2 16:27:06 1989 Randall Smith (randy at apple-gunkies.ai.mit.edu)
+ * breakpoint.c (bpstat_stop_status): Disable watchpoint
+ when we exit its exp_valid_block.
- * *-dep.c: Deleted definition of COFF_FORMAT if AOUTHDR was
- defined since 1) We *may* (recent mail message) want to define
- AOUTHDR under a basically BSD system, and 2) AOUTHDR is sometimes
- a typedef in coff encapsulation setups. Also removed #define's of
- AOUTHDR if AOUTHDR is already defined (inside of coff format).
- * core.c, dbxread.c: Removed #define's of AOUTHDR if AOUTHDR is
- already defined (inside of coff format).

-Tue Jan 31 12:56:01 1989 Randall Smith (randy at apple-gunkies.ai.mit.edu)
+ * Makefile.dist: Bump version to 3.91.3.
- * GDB 3.1 released.
+ * Clean up handling of breakpoint commands (somewhat).
+ Prompted by Tiemann bug report "cont 10" doesn't work any more.
- * values.c (modify_field): Changed test for endianness to assign
- to integer and reference character (so that all bits would be
- defined).
+ inferior.h: Add breakpoint_proceeded to inferior status struct
+ and globals; save it and restore it.
+ (clear_breakpoint_commands): Cleanup, remove old #define.
-Mon Jan 30 11:41:21 1989 Randall Smith (randy at apple-gunkies.ai.mit.edu)
+ infrun.c (clear_proceed_status): Set breakpoint_proceeded.
+ (save_inferior_status, restore_inferior_status): handle it also.
+ (proceed): Remove earlier code that set breakpoint_proceeded.
+ It is now set only in clear_proceed_status.
+ (clear_proceed_status): Cleanup, use bpstat_clear rather
+ than clear_breakpoint_commands. No callers need the stop_bpstat
+ between clear_proceed_status and proceed.
- * news-dep.c: Deleted inclusion of fcntl.h; just duplicates stuff
- found in sys/file.h.
+ infcmd.c: Add breakpoint_proceeded definition and comment.
+ (cont_command, jump_command, signal_command): Move call to
+ clear_proceed_status right next to call to proceed.
+
+ breakpoint.c (bpstat_do_actions): Avoid clobbering our
+ caller's argument while running down the chain of breakpoints.
+ Use new variable "breakpoint_proceeded" to determine when
+ a command that it executes moves the inferior past the
+ breakpoint.
+ (bpstat_clear): Handle NULL argument.
+ (bpstat_clear_actions): Avoid useless call to
+ breakpoint_auto_delete.
+ (delete_breakpoint): Clean up bpstat's that are pointing to
+ the deleted breakpoint from the stop_bpstat chain.
+ (breakpoint_auto_delete): Simplify.
+
+ * Clean up handling of EOF, error on stdin, etc. This was
+ prompted by a network problem that caused gdb to go into an
+ infinite loop filling up its malloc'd memory.
+
+ main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
+ not clear_breakpoints_commands, which is now gone.
+ (main): If command_loop returns (e.g. from EOF on stdin), do
+ a quit_command (looping back to command_loop if quit_command
+ doesn't really quit).
+ (command_loop): check result from command_line_input and
+ exit if it returns NULL, rather than passing the NULL to
+ execute_command.
+ (gdb_readline): Free malloc'd result space before returning
+ NULL for EOF.
+
+ * utils.c (query): Handle C-d to mean "yes", just as if the
+ input was not a terminal. Also avoid infinite loop if EOF
+ occurs in mid-input-line before newline. This allows
+ query to be used at EOF on stdin with reasonable results.
+
+ * infrun.c (proceed): Set breakpoint_proceeded.
+
+ * values.c (value_as_long): Avoid infinite recursion for enums.
+ (_initialize_values): Fix typo in help msg (kingdon).
+
+ * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
+ RL_LIB for linking. This allows -lreadline for linking
+ and nothing for dependencies, once readline is a real library.
+
+ * config.gdb: Jim Kingdon: give useful error message if the
+ host or target type is not recognized.
+
+ * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
+ it just defines it. Dumb, but deal with it.
+
+ * Jim Kingdon suggests:

+ * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
+ * printcmd.c: Avoid kludging a global variable (addressprint)
+ to avoid printing the address of a string twice. Instead,

+ to avoid this problem.
+ (print_formatted): Pass format arg to value_print.
+ (restore_addressprint): Remove function.
+ (do_examine): Avoid hacking addressprint, cleanups and such.
+ (print_frame_args): Add a comment to a Bothner change.

+ to wipe out the values cached in blockframe.c.
+ * symtab.c (find_method): Add comment saying how big you must
+ allocate to be "big enough". Per being terse again.
+ * valprint.c (val_print): Handle format letter "s" to print
+ strings without addresses. Add comment to vtbl printing code
+ which casts with wild abandon. Rearrange reference-printing
+ code so it prints:
+ @0xaddr: value (print w/addressprint)
+ value (print w/~addressprint)
+ @0xaddr (parameter lists w/addressprint)

+
+ * Merge more changes from Per Bothner:
+
+Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
+annoying) that I tried to improve it. Here are my suggestions.
+
+ These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
+
+ findvar.c:
+ Do automatic de-reference when taking the address of a reference.
+ printcmd.c:
+ Don't deref_ref when printing parameter lists.
+ valops.c:
+ More attempts at treating refernences properly.
+ valprint.c:
+ In val_print, if deref_ref==0, don't print dangling " = ".
+ value.h:
+ Add COERCE_REF macro, which de-references an REF.
+
+ * Merge changes from Per Bothner:
+
+* Fixed (Sony news)-specific configuration problems.
+* Fixed other problems with using vanilla pcc and libc (enum problems;
+assumption that vsprintf exists).
+* Some major speed-ups (finc_pc_partial_function now caches a match;
+parsing avoids duplicate symbol_lookup calls).
+* Changed handling of baseclasses (no longer use baseclasses field
+of struct type, use the first n_baseclasses fields instead).
+* Various minor changes/fixes, most C++-related.
+
+blockframe.c:
+Cache the most previous match from find_pc_partial_function.
+(Save both low and high ends of matching function's pc range.)
+This speeds up the loop of infrun.c:wait_for_inferior quite
+a bit, and makes step/next commands much zippier.
+command.c:
+Added an enum->int cast (otherwise, some compilers barf).
+dbxread.c:
+No longer set baseclass offset to 0, since multiple
+inheritance now mostly works.
+Added a number of casts, to shut up compiler warnings
+(after stabs where made enums, not ints).
+When discarding a symbol table (in symbol_file_command),
+must clear the cache introduced in blockframe.c.
+Don't convert $vtbl_ptr_type to vtbl any more.
+Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
+Mask off sign bit emitted by g++ for virtual table offset.
+Set voffset to -1 (not 1) for static member functions.
+expread.y:
+Changed parsing/lexing of names to avoid doing symbol lookup twice
+(once when lexing to determine symbol class, once for real).
+Now only call symbol_lookup once. Fields of 'this' win especially big.
+printcmd.c:
+Subpress printing addr twice in the case of 'x/s addr'.
+symtab.c:
+lookup_basetype_type is no longer used.
+Add find_methods as recursive helper function to decode_line_1.
+This allows multiple inheritance to work.
+Also, once one or more matches has been found, do not look in
+base-classes. (Baseclass methods would be overridden, anyway.)
+symtab.h:
+Removed baseclasses array in struct type.
+Instead of using baseclasses[i], use fields[i-1].
+Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
+Changed sign convention of voffset (previous was inconsistent).
+tm-news.h:
+Some macros (CALL_DUMMY and relatives) were missing. Put them back.
+utils.c:
+Used to assume existence of vsprintf. Re-written to not need it
+if HAVE_VPRINTF is undefined.
+valops.c:
+typecmp was too pessimistic. Made it less so.
+valprint.c:
+Don't print space after address.
+If vtable points to a misc symbol (with 0 offset), print it,
+since that indicates the actual class of the object.
+Changed ype_print_derivation_info to use new inheritance
+scheme (without baseclasses vector).
+values.c:
+In value_primitive_field, fixed some bugs left over from previous set of fixes.
+Also, changes needed because TYPE_BASECLASSES were removed.
+xm-news.h:
+REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
+
+Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
+
+ * source.c:
+ If there is no path set, and the symbols don't indicate what directory
+ a file was compiled in, look in the current directory. But either
+ a path or a known compilation directory will prevent this.
+
+ * dbxread.c:
+ Three independent bug fixes:
+ * Remove the #if 0 block that breaks some stuff.
+ * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
+ adapt gdb to either SunOS 4.0.* or 4.1.
+ * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
+
+ * symtab.c:
+ Instantiate the class T when looking for methods in it. (Tiemann@sun)
+
+ * valprint.c:
+ (type_print) Demangle the name being printed.
+ (type_print_base) Handle botched demangling without coredump (tiemann).
+
+ * values.c:
+ (check_stub_method): Document routine.
+ (tiemann) fix bug for no-arg functions
+ Avoid clobbering beyond end of malloc'd storage.
+ Terminate the argument list properly.
+
+
+ * Changes merged by John Gilmore:
+
+breakpoint.c:
+ In breakpoint_1, use new print_address_symbolic instead
+ of find_pc_partial_function. (This forces use of assembler-level
+ addresses, and avoids misleading non-mangled source-level names.)
+cplus-dem.c:
+ Generalize ansi argument such that -1 means skip arglist totally.
+ Removed global variable print_ansi_qualifiers (which made
+ code non-reentrant), in favor of extra explicit arguments
+ to internal routines.
+printcmd.c:
+ Add new helper function print_address_symbolic.
+ Use find_pc_misc_function instead of find_pc_partial_function
+ (since we want assembler-level symbols here).
+stack.c:
+ Print unknown function as just "f (...)", not "f (...) (...)".
+ Use new fputs_demangled explicitly.
+symtab.c:
+ Fixed a typing violation (problem: value.h cannot be imported
+ without renaming many variable in this file).
+ lookup_symbol: If no matching misc_func, look for a C++-mangled name.
+ decode_line_1: Moved forward some never-reached code.
+ Made decode_line_2 skip function prologues correctly.
+utils.c:
+ fputs_filtered should not demangle by default.
+ Add new fputs_demangled to demangle on demand..
+valops.c:
+ Change value_struct_elt to use value_primitive_field (using recursive
+ utility function search_struct_field). This allows foo.bar to work
+ for multiple inheritance (so far only for data fields).
+ Change check_field in the same way (recursive helper function
+ to support multiple inheritance).
+ (Note: there are more of these problems that I haven't fixed.
+ Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
+ value_of_this: 'this' symbol name is now just "this", note "$this".
+valprint.c:
+ Don't print static members.
+ Avoid printing "members of <type>" if there are none.
+ Simplified type_print_derivation_info by merging duplicate code.
+ Remove useless blank lines in type_print_base (ptype command).
+value.h:
+ Added declaration of new routine value_primitive_field.
+values.c:
+ Added value_primitive_field which is generalized version of
+ value_field that can handle multiple inheritance (non-zero offsets etc).
+ Re-implemented value_field to call value_primitive_field.
+
+Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
+
+ * infcmd.c -- insert else to avoid 'delete env' coredump when you
+ delete the whole environment. Karl Berry reported the bug.
+ * source.c - fix openp to avoid //'s in filenames, which
+ trigger an Emacs bug causing it to not be able to find files
+ when running gdb in a window.
+ * dbxread.c - zap the #if 0 that botches the add-file code.
+ It seems to work a lot better without all the code commented out.
+
+Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
+
+ * Merge Tiemann's and Ted Goldstein's changes, detailed below,
+ into gdb-3.90.9.
+
+Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
+
+ * Makefile - added a ${CFLAGS} to a couple of entries,
+ added remote-sa.sparc.c
+ * added remote.sa-sparc.c, a modification of remote.c
+ which conducts a dialog directly with the SparcStation prom.
+ * breakpoint.c, infrun.c, sparcdep.c added
+ remote_insert_breakpoint(), and remote_remove_breakpoint()
+ to breakpoint.c instead of directly writing breakpoint instructions.
+ * sparcdep.c on remote_debugging,there is no need
+ to remove signle step breakpoint instructions.
+ * main.c added "-epoch" flag and "int epoch_interface" to main.c
+ global variable
+ * printcmd.c - epoch interface sends lisp expressions to open up
+ epoch windows on inspection.
+ * valprint.c - added arrayprint, and addressprint and made adding
+ format controls easier
+ * wait.h added a couple of undef's because we were getting
+ complaints about WSTOPSIG and WTERMSIG begin redefined.
+
+
+Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
+

+
+ * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we

-Wed Jan 25 14:45:43 1989 Randall Smith (randy at apple-gunkies.ai.mit.edu)
+ * values.c (baseclass_addr): New function. Casts derived pointers

+ Insert breakpoints and continue (not step) if
+ step_resume_break_address != NULL, even if another_trap.
+ If trap_expected and we enter sigtramp, then set up a
+ step_resume_break.
+ If trap_expected is set when we hit the step_resume_break,
+ set another_trap.
+ When calling resume and trap_expected says tell resume to step
+ (2 places), also check step_resume_break_address.
- * sparc-dep.c (isabranch): Multiplied offset by 4 before adding it
- to addr to get target.
+ * infrun.c (wait_for_inferior): Don't set
+ prev_{pc,sp,func_{start,name}} before calling wait ().

-
- * dbxread.c (read_range_type): Added code to be more picky about
- recognizing builtins as range types, to treat types defined as
- subranges of themselves to be subranges of int, and to recognize
- the char type idiom from dbx as a special case.
+ * param.h, tm-88k.h: Define ADDR_BITS_*.
+ infcmd.c (jump_command, read_pc), infrun.c (wait_for_inferior),

- isn't any frame selected.
+ * breakpoint.c (bpstat_do_actions): If *BSP is set to NULL by
+ execute_command, exit both loops.
- * core.c: Made a change for the UMAX system; needs a different
- file included if using that core format.
+ * Makefile.dist: Don't set TARGET_ARCH. Add .c.o rule.
- * Makefile: Deleted duplicate obstack.h in dbxread.c dependency.
+Tue May 1 17:07:23 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
- * munch: Modified (much simpler) to cover (I hope) all cases.
+ * Makefile.dist (RAPP_OBS, rapp),
+ rgdb.c, rserial.c, rudp.c, serial.c, udp.c, xdep.h,
+ remote.h: Added.
+ m68k-xdep.c, coredep.c: Wrap in #if !defined (RDB).
- * utils.c (save_cleanups, restore_cleanups): Added functions to
- allow you to push and pop the chain of cleanups to be done.
- * defs.h: Declared the new functions.
- * main.c (catch_errors): Made sure that the only cleanups which
- would be done were the ones put on the chain *after* the current
- location.
-
- * m-*.h (FRAME_CHAIN_VALID): Removed check on pc in the current
- frame being valid.
- * blockframe.c (get_prev_frame_info): Made the assumption that if
- a frame's pc value was within the first object file (presumed to
- be /lib/crt0.o), that we shouldn't go any higher.
-
- * infrun.c (wait_for_inferior): Do *not* execute check for stop pc
- at step_resume_break if we are proceeding over a breakpoint (ie.
- if trap_expected != 0).
-
- * Makefile: Added -g to LDFLAGS.
-
- * m-news.h (POP_FRAME) Fixed typo.

- params in order by .stabs entry, not by register number.
-
- * sparc-opcode.h: Changed declaration of (struct
- arith_imm_fmt).simm to be signed (as per architecture manual).
- * sparc-pinsn.c (fprint_addr1, print_insn): Forced a cast to an
- int, so that we really would get signed behaivior (default for sun
- cc is unsigned).
-
- * i386-dep.c (i386_get_frame_setup): Replace function with new
- function provided by pace to fix bug in recognizing prologue.
+Tue Apr 24 10:25:10 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)

-
- * infcmd.c (run_command): Changed error message to "Program not
- restarted."
-
- * value.h: Changed "frame" field in value structure to be a
- FRAME_ADDR (actually CORE_ADDR) so that it could survive across
- calls.
-
- * m-sun.h (FRAME_FIND_SAVED_REGS): Fixed a typo.
-
- * value.h: Added lval: "lval_reg_frame_relative" to indicate a
- register that must be interpeted relative to a frame. Added
- single entry to value structure: "frame", used to indicate which
- frame a relative regnum is relative to.
- * findvar.c (value_from_register): Modified to correctly setup
- these fields when needed. Deleted section to fiddle with last
- register copied on little endian machine; multi register
- structures will always occupy an integral number of registers.
- (find_saved_register): Made extern.

+ * Makefile.dist (m-sun4os4.h): Depend on m-sparc.h
- * valprint.c (type_print_varspec_suffix): Added check for
- TYPE_LENGTH(TYPE_TARGET_TYPE(type)) > 0 to prevent divide by 0.
+ * Makefile.dist (version.c): Depend on Makefile.dist, not Makefile.
- * printcmd.c (print_formatted): Added check for VALUE_REPEATED;
- value_print needs to be called for that.

+Thu Feb 22 12:01:36 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
- * m-sparc.h, findvar.c: Ditched REGISTER_SAVED_UNIQUELY and based
- code on REGISTER_IN_WINDOW_P and HAVE_REGISTER_WINDOWS. This will
- break when we find a register window machine which saves the
- window registers within the context of an inferior frame.
+ * expread.y: Inlcude value.h and don't cast return value from
+ lookup_internalvar.
- * sparc-dep.c (frame_saved_pc): Put PC_ADJUST return back in for
- frame_saved_pc. Seems correct.
+ * infrun.c: Remove code in #ifdef UMAX_PTRACE.
- * findvar.c, m-sparc.h: Created the macro REGISTER_SAVED_UNIQUELY
- to handle register window issues (ie. that find_saved_register
- wasn't checking the selected frame itself for shit).
+ * values.c (convenience_info): Print in form "$foo = 5".
+ Don't print "Debugger convenience variables:" before first one.
- * sparc-dep.c (core_file_command): Offset target of o & g register
- bcopy by 1 to hit correct registers.
+ * Makefile.dist: Remove ADD_FILES from CLIBS.
+ (gdb, kdb, xgdb): Put in ADD_FILES as well as CLIBS.
- * m-sparc.h: Changed STACK_END_ADDR.
+ * m-pyr.h: #if 0 out call dummy stuff.
+ Put in POP_FRAME which just calls error().
+ valops.c: If CALL_DUMMY is not defined, put in dummy call_function
+ which just prints an error message.

+Tue Feb 20 22:11:40 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
- * sparc-dep.c (core_file_command): Added in code to get the i & l
- registers from the stack in the corefile, and blew away some wrong
- code to get i & l from inferior.
+ * breakpoint.c (commands_command): Add arg from_tty.
-Fri Oct 21 15:09:19 1988 Randall Smith (randy at apple-gunkies.ai.mit.edu)
+ * main.c (main): Put if (!setjmp (to_top_level)) around calls
+ to *_command made in response to command line arguments.
- * m-sparc.h (PUSH_DUMMY_FRAME): Saved the value of the RP register
- in the location reserved for i7 (in the created frame); this way
- the rp value won't get lost. The pc (what we put into the rp in
- this routine) gets saved seperately, so we loose no information.
+Mon Feb 19 13:58:28 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
- * sparc-dep.c (do_save_insn & do_restore_insn): Added a wrapper to
- preserve the proceed status state variables around each call to
- proceed (the current frame was getting munged because this wasn't
- being done).
+ * main.c (main): Use getopt_long_only. Move one-character options
+ to long_options. Remove entries which are just unambiguous
+ abbreviations of other options.
- * m-sparc.h (FRAME_FIND_SAVED_REGS): Fix bug: saved registers
- addresses were being computed using absolute registers number,
- rather than numbers relative to each group of regs.
+ * command.h: Add types cmd_types and var_types.
+ Add fields type, var_type, and var to struct cmd_list_element.
+ command.c (add_set_cmd, add_set_from_show): New functions.
+ (add_cmd): Set c->var_type.
+ (add_abbrev_cmd): Call add_cmd instead of duplicating code.
+ main.c: Add showlist.
+ Move parse_binary_operation from main.c to command.c.
+ command.c (do_setshow_command): New function.
+ gdbcmd.h: New file.
+ Makefile.dist: Add gdbcmd.h.
+ many files: Include gdbcmd.h, use add_set_cmd and add_show_from_set.
+ Replace info * with show * where appropriate.
+ utils.c (fputs_filtered): Use UINT_MAX in lines_per_page to mean
+ no paging.
+ defs.h: Define UINT_MAX.
+ infcmd.c (run_command): Use execute_command, not set_args_command.
+ main.c (execute_command): Call do_setshow_command if necessary.
+ main.c (show_command, show_history): New functions.
+ main.c (initialize_main): Call add_prefix_cmd
+ for show and show history.
- * m-sparc.h (POP_FRAME): Fixed a bug (I hope) in the context
- within which saved reg numbers were being interpetted. The
- values to be restored were being gotten in the inferior frame, and
- the restoring was done in the superior frame. This means that i
- registers must be restored into o registers.
+ * coffread.c (enter_linenos): Print error if
+ file_offset < linetab_offset.
- * sparc-dep.c (do_restore_insn): Modified to take a pc as an
- argument, instead of a raw_buffer. This matches (at least it
- appears to match) usage from POP_FRAME, which is the only place
- from which do_restore_insn is called.
+Sun Feb 18 15:37:05 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
- * sparc-dep.c (do_save_insn and do_restore_insn): Added comments.
+ * convex-dep.c (comm_registers_info): Fix typo. ("argc"->"arg").
- * m-sparc.h (FRAME_FIND_SAVED_REGS): Modified my code to find the
- save addresses of out registers to use the in regs off the stack
- pointer when the current frame is 1 from the innermost.

-Thu Oct 20 13:56:15 1988 & Smith (randy at hobbes.ai.mit.edu)
+ * config.gdb: Create Makefile with make.
- * blockframe.c, m-sparc.h: Removed code associated with
- GET_PREV_FRAME_FROM_CACHE_ITEM. This code was not needed for the
- sparc; you can always find the previous frames fp from the fp of
- the current frame (which is the sp of the previous). It's getting
- the information associated with a given frame (ie. saved
- registers) that's a bitch, because that stuff is saved relative to
- the stack pointer rather than the frame pointer.
+ * Makefile.dist, config.gdb: Move "srcdir=" line from Makefile.dist
+ to new file Makefile.srcdir.
- * m-sparc.h (GET_PREV_FRAME_FROM_CACHE_ITEM): Modified to return
- the frame pointer of the previous frame instead of the stack
- pointer of same.
+ * valprint.c: Include <errno.h>.
- * blockframe.c (flush_cached_frames): Modified call to
- obstack_free to free back to frame_cache instead of back to zero.
- This leaves the obstack control structure in finite state (and
- still frees the entry allocated at frame_cache).
+ * value.h: Declare value_coerce_function.
-Sat Oct 15 16:30:47 1988 & Smith (randy at tartarus.uchicago.edu)
+ * findvar.c: Add missing " after #include "gdbcore.h
- * valops.c (call_function): Suicide material here. Fixed a typo;
- CALL_DUMMY_STACK_ADJUST was spelled CAll_DUMMY_STACK_ADJUST on
- line 530 of the file. This cost me three days. I'm giving up
- typing for lent.
+ * main.c (main): Re-write command parsing to use getopt.
+ On "gdb +help" print options with '+' not '-'.
+ Makefile.dist: Add getopt.
-Fri Oct 14 15:10:43 1988 & Smith (randy at tartarus.uchicago.edu)
+Tue Feb 13 00:08:27 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
- * m-sparc.h: Corrected a minor mistake in the dummy frame code
- that was getting the 5th argument and the first argument from the
- same place.
+ * Makefile.dist: Add "srcdir=."
+ config.gdb: Edit srcdir= rather than adding it to the beginning.
-Tue Oct 11 11:49:33 1988 & Smith (randy at tartarus.uchicago.edu)
+ * pyr-dep.c: Make global_reg_offset, last_frame_offset not static.
+ Move definition of reg_stack_offset to core.c [REG_STACK_SEGMENT].
- * infrun.c: Made stop_after_trap and stop_after_attach extern
- instead of static so that code which used proceed from machine
- dependent files could fiddle with them.
+ * config/pyramid: Print message about alloca.
- * blockframe.c, frame.h, sparc-dep.c, m-sparc.h: Changed sense of
- ->prev and ->next in struct frame_cache_item to fit usage in rest
- of gdb (oops).
+ * breakpoint.c (clear_command): When printing "no breakpoint"
+ error, only use arg if non-NULL.
-Mon Oct 10 15:32:42 1988 Randy Smith (randy at gargoyle.uchicago.edu)
+ * core.c (read_memory): Rename to read_memory_noerr.
+ (read_memory): New function which calls read_memory and checks for err.
+ gdbcore.h: Declare all extern core.c functions.
+ move myread from core.c to utils.c.
+ declare it in defs.h.
+ (read_memory_integer): move from infcmd.c to core.c.
+ gdbcore.h: Declare it.
+ Many places: Remove error checking on read_memory, or call
+ read_memory_noerr instead. Include "gdbcore.h" if calling either.
- * m-sparc.h, sparc-dep.c, blockframe.c, frame.h: Wrote
- get_frame_cache_item. Modified FRAME_SAVED_PC and frame_saved_pc
- to take only one argument and do the correct thing with it. Added
- the two macros I recently defined in blockframe.c to m-sparc.h.
- Have yet to compile this thing on a sparc, but I've now merged in
- everything that I received from tiemann, either exactly, or simply
- effectively.
+ * value.h (COERCE_ARRAY): Coerce functions to function pointers.
+ valops.c (value_coerce_function): New function.
- * source.c: Added code to allocated space to sals.sals in the case
- where no line was specified.

+ * Makefile.dist, config.gdb: Put in srcdir stuff.
- * config.gdb: Added sparc.

+Fri Feb 9 08:59:37 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
- * inferior.h, infcmd.c, infrun.c: Changed the variable
- stop_random_signal to stopped_by_random signal to fit in better
- with name conventions (variable is not a direction to the
- proceed/resume set; it is information from it).
+ * config/hp300hpux: Print message telling people to use gcc.
-Thu Sep 29 13:30:46 1988 Randall Smith (randy at cream-of-wheat.ai.mit.edu)

+ config/{pn,npl}: Change name of gld-pinsn.c
- * dbxread.c (read_dbx_symtab, process_symbol_for_psymtab):
- Put *all* global symbols into misc_functions. This is what was

+Tue Feb 6 00:25:36 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)

+ m-hp300hpux.h: Define ATTACH_DETACH.

+ * main.c (initialize_main): Change alias class to aliases.

- * symtab.h, dbxread.c, symtab.c, symmisc.c: Modified to avoid

- deal with them.

-Wed Sep 14 12:02:05 1988 Randall Smith (randy at sugar-smacks.ai.mit.edu)
+ * defs.h (enum command_class): Remove comma after last element.
- * breakpoint.c, gdb.texinfo: Added enable breakpoints, disable

- to i386
+ * Move code from infptrace [USE_PTRACE_GETREGS] to sun3-dep.c.
+ m-sun{2,3}.h, m-sparc.h: Define FETCH_INFERIOR_REGISTERS.
- * printcmd.c, breakpoint.c: New commands to enable/disable
- auto-displays. Also `delete display displaynumber' works like

-Tue Jul 19 02:17:18 1988 Peter TerMaat (pete at corn-chex.ai.mit.edu)
+ * m-hp300hpux.h: Define FETCH_INFERIOR_REGISTERS.
+ infptrace.c: Put {fetch,store}_inferior_registers inside
+ #if !defined FETCH_INFERIOR_REGISTERS.
- * coffread.c: (coff_lookup_type) Wrong portion of type_vector was
- being bzero'd after type_vector was reallocated.

-Sun Jul 17 22:27:32 1988 Peter TerMaat (pete at corn-chex.ai.mit.edu)
+ * m-hp300bsd.h: Remove KERNEL_U_ADDR.
- * printcmd.c, symtab.c, valops.c, expread.y: When an expression is
- read, the innermost block required to evaluate the expression is
- saved in the global variable `innermost_block'. This information
- is saved in the `block' field of an auto-display so that
- expressions with inactive variables can be skipped. `info display'
- tells the user which displays are active and which are not. New
- fn `contained_in' returns nonzero if one block is contained within
- another.
+ * infptrace.c [!KERNEL_U_ADDR]: Get address of kernel u area
+ at runtime.

- * coffread.c, infrun.c: minor changes for the i386. May be able
- to eliminate them with more general code.
+ * kill_inferior{,_fast}: Declare as returning void.
- * default-infdep.c: #ifdef SYSTEMV, include header file types.h.
- Also switched the order of signal.h and user.h, since System 5
- requires signal.h to come first.
+ * m-sun3.h (USE_PTRACE_GETREGS): Define.
- * core.c main.c, remote,c, source.c, inflow.c: #ifdef SYSTEMV,
- include various header files. Usually types.h and fcntl.h.
+ * execcore.c: Add IS_OBJECT_FILE & related stuff.

+ * Makefile.dist (gdb1): add "rm -f gdb1".
- * Makefile, *.c, munch, config.gdb, README: New initialization
- scheme uses nm to find functions whose names begin with
- `_initialize_'. Files `initialize.h', `firstfile.c',
- `lastfile.c', `m-*init.h' no longer needed.
+ * printcmd.c (print_scalar_formatted): If size is 0, use 'b'
+ 'h', 'w', or 'g' depending on the type.
- * eval.c, symtab.c, valarith.c, valops.c, value.h, values.c: Bug
- fixes from gdb+ 2.5.4. evaluate_subexp takes a new arg, type
- expected. New fn value_virtual_fn_field.
+ * stack.c (backtrace_command): Read in symbols for frames we'll
+ print before printing them.
-Mon Jul 11 00:48:49 1988 Peter TerMaat (pete at corn-chex.ai.mit.edu)

+ ptrace. Don't print "out of bounds" for any ptrace error
+ except EIO.
- * core.c (read_memory): xfer_core_file was being called with an
- extra argument (0) by read_memory.
+ * valprint.c (type_print_base, case TYPE_CODE_ENUM):
+ Print "FOO = 5" not "FOO : 5".
- * core.c (read_memory), *-infdep.c (read_inferior_memory),
- valops.c (value_at): read_memory and read_inferior_memory now work
- like write_memory and write_inferior_memory in that errno is
- checked after each ptrace and returned to the caller. Used in
- value_at to detect references to addresses which are out of
- bounds. Also core.c (xfer_core_file): return 1 if invalid
- address, 0 otherwise.
+ * symtab.{c,h}: Make lookup_misc_func extern.
- * inflow.c, <machine>-infdep.c: removed all calls to ptrace from
- inflow.c and put them in machine-dependent files *-infdep.c.

+ cut down on calls to lookup_symbol.
+ symtab.{c,h} (lookup_primitive_typename): New function.

- format 1 can no longer be used.
+ * symtab.{c,h} (check_stub_type): New function.
+ valprint.c (type_print_base, val_print, type_print_derivation_info),
+ values.c (allocate_value): Call it.

- rather than parsing `if' as a function name and returning an
- error.

+ infrun.c (sig_print_{header,info}): Consolidate duplicated
+ code from handle_command, signals_info.

+ _initialize_utils: Call init_sig for each signal.
+ defs.h: Declare them.
- * C++: symtab.c, breakpoint.c, source.c: Merged code to deal with

- function names, so that `list classname::overloadedfuncname'
- refers to several different lines, possibly in different files.
+ * default-dep.c (read_inferior_memory): Check quit_flag in
+ fetch loop.
-Fri Jul 1 02:44:20 1988 Peter TerMaat (pete at corn-chex.ai.mit.edu)
