+ 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!):

+ xconfig/hp300hpux, xconfig/symmetry: Change names to shorter

+
+ * 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.
+
+ * 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!
- * main.c (echo_command): Don't die if not given any arg.
- * main.c (cd_command): Echo new cwd if interactive.
+ (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.?.
-Thu Feb 12 11:22:56 1987 Richard M. Stallman (rms at prep)
+ (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."
- * stack.c (initialize): "bt" now appears in help aliases.
+ * 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.
- * Version 2.0 released.
+ * 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.
+
+ * 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.
+ (REGISTER_ADDR): Make result type unsigned int.
+
+ * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
+ define REGEX must also define REGEX1 (its dependency).
+
+Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ * tconfig/i960: No longer works, points you at vxworks960 or
+ nindy960.
+
+ * xgdb.c, XGDB-README: Remove file. Users can get the much
+ better xxgdb.
+ * Makefile.dist: Remove all trace of xgdb.
+
+ * breakpoint.c (breakpoint_1): Pass demangle arg to
+ print_address_symbolic.
+ (clear_breakpoints): Remove unused function.
+ (breakpoint_re_set_one): Guts of breakpoint_re_set.
+ (breakpoint_re_set): Use catch_errors to do them all anyway.
+
+ * gdb-int.texinfo (Host versus Target): Add section on what is
+ a "host" feature versus what is a "target" feature.
+
+ * infcmd.c (path_command, path_info): Handle the PATH variable
+ (object search path) as conveniently as the source search path.
+ * environ.c (set_in_environ): Set some vars in GDB's environment,
+ in addition to the child's. PATH, G960BASE, G960BIN for starters.
+ * source.c (mod_path): New function, from guts of
+ directory_command, modifies a path. Used by path_command.
+ (directory_command): Call it.
+ * defs.h (strsave): Declare.
+
+ * utils.c (sevenbit_strings): Add new printing option.
+ (printchar): Use it.
+ (strsave): Provide this handy helper routine.
+ (set_width_command): Rename set_screen_width_command.
+ (_initialize_utils): "set screen-width" => "set width";
+ "set screen-height" => "set height"; add sevenbit-strings.
+
+ * infcmd.c (do_registers_info): Print floating point registers
+ in raw hex as well as float format, regardless of whether it is
+ a "virtual" convertible register.
+ * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
+ regs as a double, just in case it's being used that way.
+ * values.c (unpack_long): Comment on array/function coercion.
+ (unpack_double): Argument is in target byte order now. For
+ integer arguments, just call unpack_long and float the result.
+ * m68k-tdep.c: include defs.h for "const" handling.
+ * remote-nindy.c: Use ieee-float stuff.
+ (nindy_fetch_registers): Unpack double regs to host double, then
+ to extended.
+ (nindy_store_registers): Pack extendeds to host double, flip
+ around by misusing unpack_double, send as target double.
+
+ * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
+ zero, as when stopped at the first instruction of a process.
+
+ * blockframe.c: Fix filename in comment (param.h => tm.h).
+ * sparc-tdep.c (skip_prologue): More explicit nudging comments.
+ * tm-68k.h: Fix typos.
+
+Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ Changes from a bringup on the DEC Vax under Ultrix 4.0.
+
+ * coredep.c (fetch_core_registers): Pass end-address of register
+ section to register_addr as expected. Don't call supply_register
+ if we'd just pass it garbage.
+
+ * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
+
+ * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
+
+ * target.c (push_target, target_info): Cast enums to int for < or
+ > comparison.
+
+ * stack.c (print_frame_info): Identify source file & line
+ even if we can't print it.
+
+ * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
+
+Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ Clean up IEEE floating point support.
+
+ * ieee-float.h: New file.
+ * ieee-float.c: Write real routines to convert between host
+ doubles and various target IEEE extendeds.
+ * m68k-xdep.c: Eliminate assembler code for extended floats.
+ * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
+ sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
+ * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
+ REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
+ double_to_ieee_extended.
+ * i960-tdep.c: Define ext_format_i960.
+ * m68k-tdep.c: Define ext_format_68881.
+ * sparc-tdep.c: Define ext_format_sparc, though unused.
+ * Makefile.dist (HFILES): Add ieee-float.h.
+ * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
+ macros.
+
+ Obsolete the "coffstrip" program in favor of using BFD's strip.
+
+ * nindy-share/coffstrip.c: Remove file.
+ * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
+ * Makefile.dist: Remove references to nindy-share/coffstrip.c.
+ * tconfig/nindy960: Remove reference to coffstrip.o.
+
+ * Makefile.dist: Roll version number to 3.94.1 (not yet final).
+
+Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ * symfile.h: Add symfile_bfd, common between dbxread and coffread.
+ * dbxread.c: Remove static symfile_bfd.
+ * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
+ it is not used yet.
+ * inftarg.c (child_detach): Pop the child_ops vector if the
+ detach is successful.
+ * remote-nindy.c (nindy_create_inferior): Don't push a new
+ nindy_ops since nindy uses the same one for execution and memory
+ examination anyway.
+ * core.c (core_ops): Use child_attach and child_create_inferior
+ rather than default attach and create_inferior functions.
+
+ Handle floating point registers in core files.
+
+ * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
+ * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
+ This version untested since BFD doesn't yet support sun3 core
+ files.
+ * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
+ conventions. Fix comments and style. This version has not
+ been compiled yet, since we have no HP inhouse.
+ * core.c (get_core_registers): Look for two sections, ".reg"
+ and ".reg2", and pass both to fetch_core_registers sequentially.
+
+ Revise directory path yet again.
+
+ * source.c (forget_cached_source_info): Not static any more.
+ (init_source_path): New default source path is "$cdir:$cwd".
+ (dir_command): Handle variable arguments ($cdir, $cwd).
+ (source_info): Print "Compilation directory" rather than
+ "Originally compiled in" to remind people of $cdir.
+ (openp): If the path contains $cwd, use current directory.
+ (open_source_file): If compilation directory is known, replace
+ first $cdir in path with the compilation directory.
+ (print_source_lines): Even if we can't print the lines, set the
+ current symtab and line for future commands like "info source" or
+ "breakpoint". Also, error message now contains the file name,
+ line number, and file access error message.
+ (_initialize_source): Fix help text to describe changes.
+ * main.c (cd_command): Forget cached source info when we chdir.
+ * utils.c (strstr): Add simple implementation.
+
+Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
+
+ * coffread.c (read_one_sym, init_linetable, init_stringtab):
+ Byte-swap COFF symbol tables if necessary when reading them in.
+ Use complain() to replace error message in one spot. Needs
+ corresponding change in bfd/coff-code.h to make some symbol
+ swapping routines non-static.
+
+Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ Merge changes from Eirik Fuller, for UTek.
+
+ * defs.h (errno): Add declaration.
+ * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
+ hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
+ i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
+ remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
+ symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
+ declarations of errno.
+
+ * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
+
+ * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
+ <rpc/rpc.h> and <rpc/types.h>.
+
+Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ * 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.
+
+Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
+
+ Cleanup for gdb-3.94 release final:
+
+ * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
+ the .c files from vx-share and nindy-share, from the various
+ macros, since they are not found via ALLDEPFILES.
+ (SFILES): Add tm-i960.h.
+ (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
+ ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
+ in the SUBDIR list.
+ (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
+ (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
+
+Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
+
+ * am29k-tdep.c: Add contribution line.
+ (examine_prologue): Cache information about function prologues in
+ the misc-function-vector to avoid lots of references over the
+ serial line while examining instructions.
+
+ * core.c (core_close): New function made from cleanup_core.
+
+ * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
+ remote-vx.c, remote.c, target.c, target.h,
+ Update target_ops vector to add attach, close, and load entries.
+ Use add_syms_addr_command, not add_file_addr_command, for
+ add_file. Break out close routine from existing code.
+
+ * 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.
+ Lint.
+ (define_symbol): Add symbol type parameter; change callers;
+ pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
+ it to influence the symbol class on the i960.
+ (define_symbol): Swap LOC_CONST's into target byte order.
+
+ * exec.c (exec_close): New function.
+ (exec_file_command): Call it.
+
+ * findvar.c (read_relative_register_raw_bytes): Doc byte order,
+ Fix byte order of frame pointer.
+ (read_var_value): Result of 0 if var's value can't be found,
+ e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
+ LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
+ (locate_var_value): Use read_var_value and use its lazy address
+ as the location of the var's value. Lint.
+
+ * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
+ instructions.
+
+ * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
+ obsolete Intel versions in favor of vxgdb versions.
+ (check_host, byteswap, byteswap_val, reorder_val): Eliminate
+ code dealing with byte order of values, which Intel did in host byte
+ order rather than gdb-4's target byte order.
+ (i960_frame_chain_valid): Move to nindy-tdep.c.
+ (examine_prologue, skip_prologue, frame_find_saved_regs,
+ frame_args_address, leafproc_return, saved_pc_after_call,
+ pop_frame): Add vxgdb versions from Mark Fox.
+ (examine_prologue, frame_struct_result_address): Add code
+ to deal with the saved value of G13 (struct return address
+ pointer).
+ (frame_args_address): Modify Mark's version to prefer the
+ saved value over the current value in the topmost frame.
+ Cache result in the frame info to avoid performance hair in
+ callers.
+ (print_fault): Add gdb960 code for printing faults.
+ (_initialize_i960): Actually call check_host.
+
+ * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
+ add stub routines. FIXME, these currently just return zero!
+
+ * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
+ (attach_command): Call target_attach, not target_open, now.
+
+ * infrun.c (normal_stop): Make global, not static, for vx_attach.
+ (child_attach): Rename from child_open.
+ (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
+ don't confuse it with a zero step_resume_break_address.
+
+ * inftarg.c (child_detach): Eliminate inferior_pid test.
+ (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
+ never called.
+
+ * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
+ from i960-tdep.c.
+
+ * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
+ (ptype_command, display_command): Eliminate have_inferior_p and
+ have_core_file_p in favor of target_has_stack or
+ target_has_execution.
+ (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
+ code for actually finding the values of arguments, though we still
+ keep track of the maximum stack offset for use in printing unnamed
+ arguments. Handle missing FRAME_ARGS_ADDRESS.
+
+ * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
+ (struct nindy_regs): Define registers passed to/from nindy.
+ (nindy_fetch_registers, nindy_store-registers): Translate between
+ nindy and GDB formats for the registers.
+ (dcache_init): Statically allocate the cache, since it was being
+ allocated by a malloc that was never freed anyway.
+ (nindy_create_inferior): Error, not core dump, if no exec file.
+ (nindy_before_main_loop): Use target_load, not target_add_file.
+
+ * remote-vx.c (net_load): Specify large timeout for load
+ requests. Allow user to break out with INTERRUPT.
+ (net_break): Remove useless code, clean up. Change callers.
+ (parse-args, skip_white_space, find_white_space): Clean up arg
+ parsing to cope with quoted strings.
+ (net_wait, net_quit): Never call error, just return status.
+ (vx_read_register, vx_write_register): Cleanup status checking.
+ #ifdef the code based on which CPU we are using (960 or 68k),
+ FIXME, this should be completely general but it isn't yet.
+ (vx_xfer_memory, vx_resume): Cleanup status checking.
+ (vx_run_files_info): Improve message.
+ (vx_load_command): Renamed from vx_add_file_command. Allow load
+ to be interrupted.
+ (net_ptrace): Remove unused routine.
+ (vx_wait): Adopt code from vxgdb960 to cope with broken
+ connections to target machine and prompt to disconnect. Remove
+ debug printouts. Map some EVENT_'s to SIGnals.
+ (add_symbol_stub, vx_open): Print names of object files we found,
+ 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.
+ (upstack_create_inferior): #if-0 it, strata obsolete it.
+ (push_target, unpush_target, pop_target): to_close() a target
+ before unstacking it.
+ (target_info): Renamed from target_files_info.
+ (_initialize_targets): Rename "i files" as "i target", accessible
+ under both names.
+
+ * target.h: Improve comments about the target_ vectored routines.
+
+ * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
+ Convert commenting style to standard GNU style.
+ (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
+ (SKIP_PROLOGUE): No longer a no-op.
+ (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
+ (*_REGNUM): Sort register numbers.
+ (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
+ 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.
+ (FRAME_ARGS_ADDRESS): Use cached result.
+ (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
+ (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
+ (PRINT_RAMDON_SIGNAL): Call print_fault.
+ (POP_FRAME): Now works.
+
+ * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
+ option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
+ BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
+ (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.
+
+ * valarith.c (value_subscripted_rvalue): Avoid handling
+ floats and doubles specially; it gave alignment errors. Lint.
+
+ * valops.c (value_of_variable, value_of_this): Error if unknown
+ value.
+
+ * valprint.c (print_floating): Bcopy rather than pointer-deref,
+ to avoid alignment problems.
+ (value_print): Handle unknown value address.
+ (cplus_val_print): Two args are ignored; remove them. Change caller.
+ (val_print): Use unpack_long rather than pointer-deref.
+
+ * values.c: Lint.
+ (unpack_long, unpack_double): Use bcopy rather than pointer-deref
+ to avoid alignment problems.
+ (value_being_returned): Error if return value unknown.
+ (set_return_value): Add bogosity warning, FIXME. *
+
+ * TODO: A woman's work is never done.
+
+ * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
+ Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
+ Add ieee-float.o to OBS.
+ * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
+ REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
+ * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
+
+ Changes to generalize the VxWorks RPC protocol slightly, to handle
+ i960 as well as 68000.
+
+ * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
+ * vx-share/reg.h: Produce i960 regs #ifdef I80960
+ * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
+ * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
+ * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
+ * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
+ for i960. Change xdr_vectors to xdr_opaques for 68k registers,
+ so they will move in target byte order rather than network
+ byte order (happens to be the same).
+
+Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
+
+Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ * am29k-pinsn.c,
+ Add contribution lines to various files, showing where they
+ came from.
+
+ * breakpoint.c (break_insn, check_break_insn_size,
+ read_memory_nobpt): Remove to mem-break.c.
+
+ * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
+ HOST_BYTE_ORDER.
+
+ * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
+ entry has bad register number. This change is not
+ tested in this release, FIXME.
+
+ * frame.h: Eliminate Frame_unknown in favor of a simple zero.
+ tm-vax.h: Ditto.
+
+ * value.h: Force value's contents field to be aligned to hold
+ at least a double or a long long (if supported). This avoids
+ doing bcopy's in and out of the contents field.
+
+ (step_1): Avoid coredump under obscure circumstances when we
+ have no frame.
+
+ * symtab.h (misc_info): Add field to misc function vector for
+ any kind of cached information the target code desires. AMD
+ 29000 uses this to avoid repeating examine_function_prologue's.
+
+ * coffread.c: Lint. Remove static symfile, read_section_header.
+ core.c (have_core_file_p): Lint: remove.
+ expprint.c (print_subexp): Lint.
+ infptrace.c, valops.c, valprint.c: lint.
+
+ Roll in changes from vxgdb-5.0.1:
+
+ * symtab.h: Comment byte order of each address class. Add
+ LOC_LOCAL_ARG for frame-relative args (960).
+ expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
+ symtab.c, symmisc.c: ditto.
+
+ * infrun.c (init_wait_for_inferior): Clear stop_signal.
+
+ * remote.c (remote_resume): Error if resume with a signal.
+
+ * symfile.c (prim_record_misc_function): Clear misc_info.
+ (fill_in_vptr_fieldno): Check stub type of arg.
+
+ * 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...
+
+Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ Roll in changes from final AMD 29000 port (Tiemann).
+
+ 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.
+ (program_info): Print target info rather than "process number";
+ avoid gratuitous messages unless from_tty.
+ (run_stack_dummy, finish_command): Set proceed_to_finish.
+ infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
+ main.c: Lint. Lose have_inferior_p().
+ inferior.h (have_inferior_p): Remove, lint.
+ (proceed_to_finish): Add flag to ask that all regs be saved
+ by normal_stop, for the few commands that need it, speeding up
+ serial I/O. Add comments to stop_registers.
+
+ * remote-eb.c: Remove newline from breakpoint message we grep
+ for. Never time out when running the user program.
+
+
+
+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.
+ Fixes bug of truncated stack reports.
+
+ * target.h (target_lookup_symbol): Define this routine's args
+ and result, finally.
+
+ * target.c (nosymbol): Default routine for target_lookup_symbol.
+ (target_default): Default lookup_symbol and call_function too.
+ (files_info): Only print has_all_memory warning if a non-dummy
+ target follows.
+
+ * remote-vx.c (vx_read_register, vx_convert_to_virtual,
+ vx_convert_from_virtual): If target does not have floating point,
+ zero register "values", and avoid doing cross-net conversions.
+ (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-vx.c (net_load): make static; avoid sophomoric msg.
+ (vx_xfer_memory): Return correct result!
+ (vx_files_info): Indicate whether target has float or not.
+ (vx_lookup_symbol): Complain, not error, if target gone.
+ (vx_open): Print "Connected" msg before disabling immediate-quit.
+ [FIXME: lookup_symbol and vx_open changes need testing.]
+
+ target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
+ tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
+ contributor lines and update copyrights to 1991.
+
+ Changes from an attempted H-PUX host port:
+
+ * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
+ defines PT_ATTACH and PT_DETACH but not PT_KILL.
+ * 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
+ "core_file_command" routine to BFD regime. May not work yet.
+
+ Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
+
+ * xgdb.c: Replace X10 version with some VJ version.
+ (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
+ (gleaned from include files, and "nm's" of binary libraries, since
+ I had no doc available).
+ (append_selection, append_selection_word): Disable with FIXME
+ since R4 changed interface here.
+ (create_buttons): Add back the old set of buttons.
+ (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
+
+ * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
+ Roll VERSION to 3.94 (not yet final though).
+
+Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ * 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.
+
+ * coffread.c (find_linenos): Avoid desupported BFD interface
+ to line numbers. We still read them manually rather than using
+ BFD's "generic" features.
+
+ * gdbrc.tex, threecol.tex: Add GDB reference card and its
+ formatting code.
+ Makefile.dist: Add refcard to OTHERS list for creating tar files.
+
+ * Makefile.dist: Eliminate use of $< in explicit targets.
+
+ * readline/Makefile: Use $< rather than $*.c, which does not
+ include the VPATH in GNU Make.
+
+ * 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.
+
+ * tm-88k.h: Fix multiline macro that lacked \'s. Remove
+ COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
+ automaticaly.
-Wed Feb 11 17:45:45 1987 Richard M. Stallman (rms at prep)
+ * TODO: Think of more things to do.
- * m68k-opcode.h: Errors corrected in several instructions
- and reordering done for assembler's sake.
+Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
- * m-vax.h (POP_FRAME): End with call to set_current_frame.
+ 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.
-Tue Feb 10 15:06:07 1987 Richard M. Stallman (rms at prep)
+ tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
+ equivalent to sun?os4 so global config works.
- * infrun.c (wait_for_inferior): Set stop_print_frame to 1
- after checking breakpoint condition.
+Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
- * infcmd.c (run_stack_dummy): Save many flags.
+
+ * 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.
-Thu Feb 5 07:12:20 1987 Richard Mlynarik (mly at prep)
+Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
- * source.c (directory_command):
- Step over `:'
+ Further stabilization for the Intel 960.
-Mon Feb 2 23:40:32 1987 Richard M. Stallman (rms at prep)
+ * 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.
- * infcmd.c (set_environment_command): Fix stupid error
- for case where no "=" appears in the string.
+ * README: Document moving include files, improve some of
+ the other doc.
-Mon Jan 26 13:46:52 1987 Richard M. Stallman (rms at prep)
+ * 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): Round end-of-arg offset
- up rather than down to multiple of int.
+ * 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.
-Fri Jan 23 15:11:50 1987 Richard M. Stallman (rms at prep)
+ * coredep.c (register_addr): Accept this routine from core.c.
- * source.c (directory_command): If dir is not added cause already
- present, print explanation.
+ * 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.
- * infrun.c (proceed): Use read_pc (), not stop_pc,
- to get current pc to think about. stop_pc could have been
- clobbered by call_function.
+ * 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.
-Fri Jan 23 15:00:55 1987 Richard Mlynarik (mly at prep)
+ * gdb-int.texinfo: Add minor sections on configuring gdb for
+ release, and about the README file.
- * source.c (directory_command):
- If dir is already in source_path, don't append another copy of it.
+ * infcmd.c (registers_info): Fix formatting somewhat. Still
+ not as pretty as before, but it handles byte swapping.
-Thu Jan 22 00:31:03 1987 Richard M. Stallman (rms at prep)
+ * 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!
- * Version 2.0.
+ * 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.
- * blockframe.c (get_pc_function_start):
- Understand misc functions.
+ * 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.
+
+ * symtab.h: Remove file-reading things to symfile.h.
+
+ * symtab.c: Remove file-reading things to symfile.c.
+
+ * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
+ to decode i960 fault types.
+
+ * 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.
+
+Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
+
+ * main.c: Replace "stupid" with "caution"; you now "set caution
+ on or off".
+
+ * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
+
+ * 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.
+
+ * 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.
+
+ * remote.c (remote_open): If arg is null, print help rather than
+ dumping core.
+
+ * 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.
+
+ * 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.
+
+ * i960-pinsn.c (reg), i960-tdep.c: Lint.
+
+ * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
+ more parameters than it used to.
+
+ * 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.
+
+ * sparc-tdep.c, valops.c: Use write_memory rather than
+ target_write_memory, to get error checking.
+
+ * 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.
+
+ * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
+
+ * symfile.h: New file, defining the interface between the
+ generic and object-file-specific symbol reading code.
+
+ * 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.
+
+ * target.c (target_command): use target_kill.
+
+ * target.h (target_files_info): Don't declare, never called
+ from outside.
+
+ * 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.

+
+
+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.
- * core.c (core_file_command):
- Copy all register contents into the array `registers'
- Save a.out header of executable file in core_aouthdr.
- Print name of executable file that was running, if we know
- where to find it.
+ * 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.
- * core.c (exec_file_command):
- Save a.out header in exec_aouthdr and file's mtime
- in exec_mtime.
+ * 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.
- * core.c (validate_files): Check that core file's a.out hdr
- matches exec file's.
+ * target.h: Breakpoint takes a char * save area, not a char **.
- * New handling of registers:
- Now all registers are fetched once when the program stops or
- when a core file is selected. Their contents are kept in
- `registers', an array of bytes. This is done by
- `fetch_inferior_registers'. `read_register', etc., just look
- there. Writing a register works through
- `store_inferior_registers' which writes one or all registers
- from `registers' back to the inferior.
+ * 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.
- A register now can have a "raw" data format and a "virtual"
- data format, which may require conversion or even be different sizes.
- The conversion can be different for different registers.
- For example, the 68000 cpu registers need no conversion
- and both raw and virtual size is 4, but the 68881 floating point
- registers have raw size 12 (for extended fmt) and virtual size 8
- (for double). Macros in the m- file such as REGISTER_BYTES,
- REGISTER_BYTE, REGISTER_{RAW,VIRTUAL}_SIZE, and
- REGISTER_CONVERT_TO_{RAW,VIRTUAL} control these things.
+ * utils.c: Remove old my_bfd_read routine.
- `read_register' and `write_register' are usable only on registers
- which hold an int and need no conversion (raw fmt = virtual fmt).
- For other registers, `read_register_bytes' is used, or
- `read_relative_register_raw_bytes'.
+ * 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).
- * m-sun3.h: Define the 68881 fp registers.
- Know how to recognize insns that save them.
- Make dummy frames save them.
+ * 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.
- * core.c (read_register, write_registers): Functions deleted.
- * findvar.c (read_register, write_registers): New functions,
- not the same as the old ones of the same name.
+ * 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.
- * findvar.c (supply_register): Function used by
- fetch_inferior_registers, etc., to install the register
- values fetched from 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.
- * findvar.c (read_register_bytes, write_register_bytes):
- Read spec'd number of bytes from the byte-array `registers'.
+ * 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.
- * findvar.c (read_relative_register_raw_bytes):
- Replaces old function `read_relative_register'; accepts
- address of where to store the contents; # bytes stored is size
- of the specified register in raw format.
+ * remote-vx.c (target_command -> vx_open): Use new generic
+ target command.
+ * remote-eb.c, inftarg.c, exec.c: ditto.
- * findvar.c (value_of_register, read_var_value):
- Convert register values and values of register variables
- from raw format to virtual format.
+ * 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.
- * findvar.c (locate_var_value): Like `read_var_value' but
- returns value for variable's address.
+ * 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.
- * value.h: Add new field VALUE_REGNO to each value. It holds
- register number to control virtual-to-raw conversion
- for assignments to the value.
+ * 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.
- * valops.c (value_assign): Convert data from virtual to raw format
- if value came from a register variable.
- Use read_register_bytes and write_register_bytes.
+ * findvar.c (find_saved_register): Avoid problem in current frame.
+ (read_relative_register): Ditto.
+ (write_register): Convert byte order on the way out.
+ * exec.c (file_command): Add.
+ (add_to_section_table, exec_command): Use new bfd_map_over_sections.
+ (xfer_memory): Common function between core_xfer_memory and
+ exec_xfer_memory.
+ (exec_xfer_memory): Use it.
- * infcmd.c (continue_command): Subtract 1 from arg
- before setting breakpoint's ignore-count.
+ * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
- * infcmd.c (jump_command): Query if spec'd line is outside
- of the current function.
+ * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
+ valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
+ infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
- * infcmd.c (finish_command): Now finish the selected frame,
- and no arg required.
+Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
- * infcmd.c (set_environment_command): Allow space to separate
- varname and value.
+ Merge Intel 960 port of gdb, continuing...
- * infcmd.c (registers_info): Print both raw and virtual data
- format if they differ. Allow register name as arg.
- Ask for a Newline each 16 registers.
+ * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
+ symbol_file_command): Pass from_tty arg to hush 'em up.
- * inflow.c (kill_inferior): call mark_breakpoints_out.
- * inflow.c ({fetch,store}_inferior_registers for Sun):
- Get the fp registers and store them in right places in
- `registers'.
- * inflow.c ({read,write}_inferior_register): Deleted.
+ * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
+ Add magic numbers for 960 COFF format.
- * infrun.c (wait_for_inferior): Single-stepping is not considered
- to have hit a breakpoint unless the pc before the step matches the
- address of the breakpoint. Necessary on machines where
- breakpoints leave the pc incremented.
+Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
- If shell gets SIGSEGV, pass the signal silently to it.
+ Merge Intel 960 port of gdb, from Intel "1.2" release.
- * m68k-pinsn.c, m68k-opcode.h:
- Add the 68881 instructions. New operand codes `F', `I', `s'
- and `k' are needed for them. New place codes `78tcik'.
- NEXTBYTE now skips a word but fetches just a byte.
- Explicit sign-extension removed from NEXTBYTE and NEXTWORD.
- NEXTSINGLE, NEXTDOUBLE, NEXTEXTEND and NEXTPACKED defined.
- Various changes to implement the new operand and place codes.
- print_index changed because displacement-size codes for
- word and long displacement were interchanged.
+ CHANGE_LOG entries from their port, which was based on
+ gdb+-2.8.0:
- * m68k-pinsn.c (convert_{from,to}_68881): Functions added
- to support REGISTER_CONVERT_TO_{RAW,VIRTUAL} on 68000.
+ Thu Sep 6 11:02:22 PDT 1990
+ Remove temp file if download is interrupted.
- * main.c (main): Move around calls to setjmp.
- * main.c (define_command, document_command):
- Accept a from_tty argument instead of calling input_from_terminal_p.
+ Wed Aug 1 09:08:33 PDT 1990
+ Now uses binary protocol to talk to NINDY.
+ Old hex protocol (NINDY 2.13 and older) supported with -O switch.
+ Times out after 5 seconds when trying to talk to NINDY.
- * printcmd.c (address_info): Print info on class and address
- of a specified symbol. For register symbols, gives name of register.
+ Tue May 29 12:54:49 PDT 1990
+ Added variable baud rate (-b switch).
+ Source code reorganization.
+
+ Thu Apr 26 11:09:55 PDT 1990
+ More cleanup of batch mode; specifically, execute "-s", "-e", and
+ "-se" switches as soon as they are encountered on the invocation line.
- * printcmd.c (print_command): Remember explicitly whether
- `make_cleanup' was called.
+ Fri Apr 20 13:47:15 PDT 1990
+ Add -brk switch.
+
+ Thu Apr 19 09:54:28 PDT 1990
+ Add 'reset' command.
- * printcmd.c (print_frame_args): Know how arg-addresses vary with
- data type on big-endian machines.
+ Wed Apr 18 09:48:07 PDT 1990
+ 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).
+
+ Mon Apr 4 16:33:05 PDT 1990
+ Some output was not being suppressed in 'batch' mode.
- * source.c (directory_command): Detect `:' in arg and reject it.
- Free the old directory-path. Simplify things like `/.' in
- dirname.
+ Thu Mar 22 15:31:11 PST 1990
+ Ask user if old symbol table should be deleted when new file is
+ downloaded.
- * source.c (openp): Simplify `./' in specified name.
+ Allow user to run a program downloaded before gdb960 was brought up.
- * source.c (find_source_lines): Compare source mtime against
- `exec_mtime' and warn if source is newer.
+ Correct "exec-file" help message for i80960 context.
- * source.c (line_info): No arg means use last line listed
- or line following last one this command was used on.
- If from tty, clear out argument so Return is like `i li' without
- arg.
+ Correct bug in calculating user space address: could occasionally
+ corrupt user program.
- * stack.c (frame_info): Print addresses registers are saved at.
+ Make sure to zero low-order bits in rip's because of bug in 960CA
+ A-step part: could cause operation faults when "next"ing across
+ a function call.
- * stack.c (return_command): When asking for confirmation, give
- name of function that will be made to return.
+ Correct bug that made it impossible to get source line numbers for
+ code loaded at addresses higher than 0x7fffffff.
- * valops.c (call_function): If function type is
- pointer-to-function, dereference it to compute return type.
- If pointer-to-object, assume function returns int.
- If char, assume that the value's address is the function address
- (because it's a misc functon). If int, the value itself is the
- function address.
+ Wed Jan 10 12:43:22 PST 1990
+ Open remote tty for exclusive use.
- * dbxread.c (compare_symbols): Sort register symbols
- before all others.
+ Fri Jan 5 12:14:42 PST 1990
+ Correct disassembly (CA manual was right after all):
+ opcode for sysctl is 0x659
- * eval.c (evaluate_subexp_for_address): New function like
- `evaluate_subexp' but returns a value for the address where
- the subexpression's value would be located.
+ Mon Oct 23 12:03:04 PDT 1989
+ Use G960BASE and G960BIN environment variables to find 'sx' utility.
+
+ Mon Oct 16 14:15:09 PDT 1989
+ "sfr0"-"sfr31" should have been named "sf0"-"sf31"
- * eval.c (evaluate_subexp_for_sizeof): New function like
- `evaluate_subexp' but returns a value for the size of the subexp.
+ Mon Oct 2 15:56:31 PDT 1989
+
+ Added 960CA disassembly support.
- * eval.c (evaluate_subexp_with_coercion): Like `evaluate_subexp'
- but coerces arrays to pointers (without taking the time to
- read the array contents).
+ To simplify maintenance:
+ - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
+ directly instead.
+ - eliminated opcode.h: incorporates tables into i960-pinsn.c
+ - moved 960-specific routines from i960-pinsn.c to i960-md.c
+ - made disassembly interface identical to that in gdmp960.
+
+
+
+Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
- * eval.c (evaluate_subexp): Use the three new functions above
- when appropriate instead of calling self recursively.
+ * target.h: Allow targets to stack. Add target_has_memory,
+ _registers, etc. Restructure memory access and "info files"
+ to walk the target stack.
+ * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
+ target.c: Change tables to match target.h.
+ * inflow.c (child_mourn_inferior): pop child_ops.
+ (generic_mourn_inferior): Use new has_stack flag.
+ * infptrace.c (child_xfer_memory): New memory regime.
+ * inftarg.c (child_files_info): New "info files" regime.
+ * remote-eb.c: New memory regime, new info files.
+ * remote-vx.c: New memory regime, new info files. Now use
+ separate targets for VxWorks attachment to machine, and
+ actually running a process under VxWorks, since one has
+ stack & execution & regs and the other doesn't.
+ * remote.c: New memory regime, new info files.
+ * sparc-xdep.c (fetch_core-registers): New memory regime.
+ * target.c: New routines and support for stacked targets,
+ new memory regime, new info files regime.
+
+
+ Generalize section handling for an arbitrary number of sections,
+ including use of the new BFD (binary file) library.
+ * gdbcore.h: Add struct section_table.
+ * exec.c (build_section_table): Iterate all sections and
+ record what gdb needs to know about them.
+ (exec_command): Use it.
+ (exec_xfer_memory): Use the table.
+ (exec_files_info): Print the table.
+ * core.c (core_file_command, core_xfer_memory, core_files_info):
+ Likewise.
+ * source.c (find_source_lines): Use bfd_get_mtime.

+ * core.c (core_fetch_registers): Get from the ".regs" section of
+ the BFD core file.
+ * sparc-xdep.c (fetch_core_registers): Use the .regs info.
+

+ * infcmd.c (run_command): use new target_create_inferior.
+ * infrun.c (child_create_inferior): Don't return result.
+ * Makefile.dist (VERSION): 3.91.4.
+
+Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
+
+ * breakpoint.c (bpstat_num): Handle breakpoints which have
+ since been deleted, such as temporary breakpoints.
+ infcmd.c (program_info): ditto.
+
+ * core.c (core_file_command): Display the frame where the core
+ dump occurred.
+
+ * main.c: lint.
+
+ * remote-vx.c (target_command): Merge in target command from
+ targ-vx.c. A few other cleanups.
+
+ * TODO, Projects: Lots more stuff to do...
+
+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.
+
+ * 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.
+
+ * 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
+ non-Unix-children handle this with their own code in the target
+ transfer vector.
+
+ 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,
+ target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
+ ${srcdir} versions of munch and createtags are used.
+
+ * valops.c (find_function_addr): Split out of call_function.
+ (call_function_by_hand): Rename call_function; this function
+ calls functions in the target by laboriously patching the target
+ word-by-word with the right stack, args, regs, etc.
+
+
+Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
+
+ Handle AMD 29000 a bit better.
+
+ * remote-eb.c (readchar): Mask received char log to make it readable.
+ (remote_start): Pass arguments down to executing program.
+ Make startaddr unsigned.
+ infrun.c (start_inferior): Accept args, pass them to
+ remote_start.
+ infcmd.c (run_command): Pass args down to start_inferior.
+
+ * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
+ the target object file format.
+ tm-29k.h: Pay heed to COFF_ENCAPSULATE.
+
+ * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
+ am29k-tdep.c (examine_prologue): Better checking of function prefixes.
+
+Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)

+ * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.

+Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
+
+ * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
+ bfd stuff is still screwed up, but with some manual work, it
+ compiles.
+
+ * breakpoint.c (bpstat_do_actions): Start over if a command
+ proceeds the inferior, since the inferior will have stopped and
+ will need to have its new stop-actions taken care of.
+
+ * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
+ 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-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
+ 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
+ "printf"!!!
+
+ printcmd.c (print_command_1): Pass 'inspect' flag down as a global
+ variable, inspect_it.
+ valprint.c (print_string, val_print): Use the global inspect_it
+ to indicate whether to print in Epoch style or normal style.
+
+Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
+
+ * printcmd.c (call_command): add an alias for the "print" command
+ which runs expressions and doesn't print the result if void.
+ (print_command_1): implement it.
+
+ * command.c: Remove #if 0'd code. Initialize all the fields
+ in add_cmd (). Rename do_nothing_command to
+ not_just_help_class_command, and make it externally visible.

+ * main.c (define_command): Don't overload c->function with a char
+ string as well as a function pointer.

+ calling convention of value_struct_elt () that got dropped in
+ merge.

+
+ * sparc-xdep.c (store_inferior_registers): defer stores to regs
+ until a good time (e.g. when we are about to run the child),
+ saving ptrace calls.
+ * infrun.c (proceed): handle DO_DEFERRED_STORES.
+ * 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.

+
+Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
+
+ * Merge Mike Tiemann's multiple inheritance changes from Sun.
+ Store the baseclasses in a type struct starting from array element
+ 0 rather than from the unusual array element 1.

+ dbxread.c: the above.
+ (virtual_context): Add
+ Read new debug information about which virtual function table
+ a virtual function is from, and store it in fn_field.fcontext.
+
+ symtab.h: Add fcontextt. Fix baseclass indices. Typo in
+ TYPE_FN_FIELD_STATIC_P.
+
+ symtab.c: the above.

+ offsetting to the proper object when calling virtual fns.

+Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
+
+ * dbxread.c (read_struct_type): Clear bit vectors whenever
+ 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.
+
+ * Remove psymtab hair from many places. Remove duplicated code
+ for searching symbol tables. Hide psymtabs from most places.
+ Make it fast to get from a psymtab to its symtab.
+
+ blockframe.c (blockvector_for_pc): Remove psymtab hair.
+ coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
+ mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
+ dbxread.c: export psymtab_to_symtab, make it work if called N times.
+ (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
+ new symtab completely. New psymtabs get symtab pointer
+ initialized to zero. Remove MI warning printf.
+ symtab.h: Comments. Add psymtab to symtab pointer.
+ (PSYMTAB_TO_SYMTAB): New macro.
+ symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
+ source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
+ 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.
+
+ * 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
+ pointers are the same.
+
+ * command.c (do_nothing_command): lint
+ dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
+ fix comments on debug symbol format for visibility. Actually set
+ visibility of symbols.

+ pointing past end of allocated memory; saber complains.
+ obstack.h: Declare the external functions that we use.
+ valarith.h: use <string.h>
+ solib.c (solib_add): lint.

- select the frame that we get to.
+ * tm-news.h: Remove inadvertently duplicated stuff.

+
+ * 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.)
- * breakpoint.c (condition_command): If no condition spec'd,
- print "breakpoint N now unconditional".
+ 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)
+
+ * Hack up 3.90.11 changes:
+
+ * Makefile.dist (depend): parameterize $(GCC).
+ Add solib.c and solib.o.
+ (readline): Fix vpath for both absolute or relative SRCDIR.
+
+ Also, let the part I didn't understand at least compile so
+ I can test the rest. FIXME.
- * breakpoint.c (commands_command): Give different error messages
- for cases of args not containing a breakpoint number
- and args containing anything after the breakpoint number.
+ * 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.)
- * commands.c (lookup_command): Don't store a zero in *p
- if have an undefined subcommand that is not an error.
+ * 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.)
- * commands.c (lookup_command): For recursive call,
- pass subcommand list properly. Was passing the address
- of the word containing the list.
+ * 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.
- * core.c ({core,exec}_file_name): If no arg, tell user
- what the effect is.
+ * symmisc.c: include param.h to get CLEAR_SOLIB.
- * dbxread.c (define_symbol): Accept class code 'v'
- for static variable within a function.
+Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
- * dbxread.c (read_type): Now allow any plain number or
- pair of numbers in parens, with no code letter. This means
- define new type same as type with specified number, or define
- it as void if specified number's type is not yet mentioned.
+ * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
+ to 3.90.11. ChangeLog entries below are from this.
- * m68k-pinsn.c (print_insn_arg): Case of general operand
- in byte insn that happened to be immediate used wrong arg-size.
+Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
- * printcmd.c (set_next_address): Set next_address from arg
- and also set value of `$_' from it.
+ * Version 3.90.11.
- * printcmd.c (do_examine): Save address in last_examine_address
- and value fetched to examine in last_examine_value.
+ * Makefile.dist (HFILES): Add tm-sunos.h.
- * printcmd.c (x_command): Copy last_examine_{address,value}
- into values of `$_' and `$__'. Change `x' documentation string.
+Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
- * source.c (directory_command): Query when no args now says
- what new value it wants use for the path.
+ * Version 3.90.10.
- * source.c (list_command): Don't die in cases like `list ,+30'.
+ * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
- * source.c (line_info): Call `set_next_address' to make `x'
- display the text of the line. Change `info list' doc string.
-Sat Nov 29 07:59:29 1986 Richard M. Stallman (rms at prep)
+ * sparc-opcode.h Added single-operand version of rett.
- * printcmd.c (undisplay_command): If get no arg,
- rather than crashing, query and then delete undisplay everything.
+Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
-Fri Nov 28 15:43:52 1986 Richard M. Stallman (rms at prep)
+ * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
+ Put parens around gcc_p in expansion.
- * dbxread.c (process_one_symbol): If N_LBRAC sym
- has a greater value that N_RBRAC, ignore the
- N_LBRAC value and give the block zero length.
+Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
-Tue Nov 25 03:10:12 1986 Richard M. Stallman (rms at prep)
+ * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
- * dbxread.c (process_one_symbol): Ignore N_NSYMS symbols
- that appear in Ultrix.
+Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
-Sat Nov 22 22:49:06 1986 Richard M. Stallman (rms at prep)
+ * 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.
+ (psymtab): New field addr.
+ 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.
- * version.c: version 1.10.
+Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
- * valprint.c (type_print*):
- SHOW < 0 now means abbreviate struct/union members
- or enum values with `...'. SHOW now decremented on
- each recursion in type_print_base. Several places
- that used to check !show now check show <= 0.
+ * infcmd.c: Change cont_command to continue_command and "cont"
+ to "continue".
- * valprint.c (val_print): Pass -1 for SHOW to type_print
- when printing typename inside parens or braces.
+Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
- * printcmd.c (print_command): If no value specified to print,
- print the value of $.
+ * breakpoint.c (enable_breakpoint): Get value of watchpoint.
- * expression.h, expread.y, eval.c, expprint.c:
- OP_MEMVAL renamed UNOP_MEMVAL
- and now allows any expression, not just an integer address.
- It now has same format as UNOP_CAST and works almost like it.
- Each place that referred to it has been rewritten
- starting with a copy of the code that handles UNOP_CAST.
- Doc for `print' command changed for this.
+ * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
- * source.c (init_source_path):
- Free and zero out any line_charpos's saved in source symtabs.
+ * values.c (USE_STRUCT_CONVENTION): Check for structures of
+ size 1,2,4,8 rather than size < 8.
- * breakpoint.c (condition_command):
- Parse the condition in the environment of the code where the
- breakpoint is set. This requires finding the breakpoint
- before parsing, so code is rearranged.
+ * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
+ as necessary, not just once.
- * dbxread.c (dbx_alloc_type):
- New function given typenums returns the type for those typenums
- or allocates a new, empty type for those typenums and returns it.
+ * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
- * symtab.c (smash_type_to_{pointer,function}):
- New functions modify an already-allocated type object
- to be a pointer to or function returning some given type.
+Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
- * dbxread.c (read_type): Uses dbx_alloc_type in many cases.
- Reading a pointer or function type now works by doing that,
- then reading the value type or type pointed to, then smashing
- it into the type already allocated. This makes some fwd refs win.
- Likewise for structs and unions.
+ * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
- * dbxread.c (read_struct_type): Now receives the type object
- as args. Used to get typenums as args and look up the type
- itself.
+ * tm-news.h: Add CALL_DUMMY_*.
- * dbxread.c (symbol_file_command):
- At very end, clear out any type name that `char *' has received.
+ * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
-Thu Nov 20 16:43:53 1986 Richard M. Stallman (rms at prep)
+ * config.gdb: In list_host, list_target, use ${i}, not $i.
- * m-sun2.h, m-sun3.h (FIND_FRAME_SAVED_REGS):
- Was incrementing address even for regs not saved.
+Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
-Sun Nov 16 14:59:07 1986 Richard M. Stallman (rms at prep)
+ * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
- * values.c (value_field): Was adding in byte offset
- before calling unpack_field_as_long, which itself
- adds in the offset. Now pass addr of start of structure.
+ * sparc-opcode.h: Change all store floating-point state register
+ instructions to have the right match & lose fields.
- * infrun.c (normal_stop): Clean up inferior_pid conditionals:
- just return early if no inferior.
+Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
-Thu Nov 13 15:45:50 1986 Richard M. Stallman (rms at prep)
+ * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
+ VPATH to readline.
+ config.gdb: If srcdir != ., create readline directory and
+ copy a makefile into it.
- * dbxread.c (struct header_file): add new field .instance
- to distinguish the various entries for one header file.
+ * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
+ consistency with POSIX.
- * dbxread.c (process_one_symbol): Use the `value' of
- a N_BINCL or N_EXCL as the instance code for the header file.
+ * breakpoint.c (bpstat_stop_status): Disable watchpoint
+ when we exit its exp_valid_block.
- * dbxread.c (add_{new,old}_header_file):
- Accept an instance code as arg and treat it as if it were
- part of the file name for distinguishing and finding entries.
+Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
- * dbxread.c (add_new_header_file, read_type):
- Turn off the header_file_prev_index feature with #if 0.
+ * Makefile.dist: Bump version to 3.91.3.
- * values.c (unpack_field_as_long, modify_field):
- Run-time test to distinguish big and little endian machines
- and do shifting accordingly.
+ * Clean up handling of breakpoint commands (somewhat).
+ Prompted by Tiemann bug report "cont 10" doesn't work any more.
-Tue Nov 11 00:31:18 1986 Richard M. Stallman (rms at prep)
+ inferior.h: Add breakpoint_proceeded to inferior status struct
+ and globals; save it and restore it.
+ (clear_breakpoint_commands): Cleanup, remove old #define.
- * version.c: version 1.9.
+ 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.
- * breakpoint.c (delete_command):
- Don't query if 2nd arg is zero.
+ 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:
+ in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
+
+Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
+
+ * Makefile.dist (VERSION): Bump version # to 3.91.2.
+
+ * Clean up Bothner's changes.
+
+ * blockframe.c (clear_pc_function_cache): New function.
+ * blockframe.c: remake cache_pc_function_* static.
+ * dbxread.c (symbol_file_command): remove references to
+ cache_pc_function_* variables.
+ * 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,
+ pass the format letter 's' down low enough that it can be seen
+ 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.
+ * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
+ * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
+ 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)
+ or nothing (parameter lists w/o addressprint)
+
+Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
+
+ * 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.)
