depends on the system) if the library lacks it (controlled by
LACK_VPRINTF_DEFINE in makefile). Unpleasant, but necessary to

machine/vmparam.h (as per John Gilmore's suggestion).
* blockframe.c (get_prev_frame_info): Changed this function back

necessary.
* Makefile: Added comment about compiling on isi under 4.3.

cannot execute code on the stack segment.
* valprint.c (val_print): Make sure that array element size isn't
zero before printing. Set address of default array to address of

* expread.y: Added precedence rules for arglists, ?:, and sizeof
to eliminate some shift-reduce conflicts.
* Makefile: Modified "Expect" message to conform to new results.
Thu Apr 13 12:29:26 1989 Randall Smith (randy at plantaris.ai.mit.edu)

deal with coprocessor branches, and improved comment.
(single_step): Changed to trap at npc + 4 instead of pc +8 on
annulled branches. Changed name in call to isabranch as above.

os 4.0.
Sat Apr 8 17:04:07 1989 Randall Smith (randy at apple-gunkies.ai.mit.edu)
* dbxread.c (process_one_symbol): In the case N_FUN or N_FNAME the
value being refered to is sometimes just a text segment variable.
Catch this case.
* infrun.c (wait_for_inferior), breakpoint.c
(breakpoint_stop_status): Move the selection of the frame to
inside breakpoint_stop_status so that the frame only gets selected
(and the symbols potentially read in) if the symbols are needed.
* symtab.c (find_pc_psymbol): Fixed minor misthough (pc >=
fucntion start, not >).
* breakpoint.c (_initialize_breakpoint): Change "delete" internal
help entry to simply refer to it being a prefix command (since the
list of subcommands is right there on a "help delete").
Fri Apr 7 15:22:18 1989 Randall Smith (randy at apple-gunkies.ai.mit.edu)
* blockframe.c (find_pc_partial_function): Created; figures out
what function pc is in (name and address) without reading in any
new symbols.
* symtab.h: Added decl for above.
* infrun.c (wait_for_inferior): Used instead of
find_pc_function_start.
* stack.c (print_frame_info): Used instead of hand coding for same
thing.
* dbxread.c (psymtab_to_symtab): No longer patch readin pst's out
of the partial_symtab_list; need them there for some checks.
* blockframe.c (block_for_pc), source.c (select_source_symtab),
symtab.c (lookup_symbol, find_pc_symtab, list_symbols): Made extra
sure not to call psymtab_to_symtab with ->readin == 1, since these
psymtab now stay on the list.
* symtab.c (sources_info): Now distinguishes between psymtabs with
readin set and those with it not set.
* symtab.c (lookup_symtab): Added check through partial symtabs
for name with .c appended.
* source.c (select_source_symtab): Changed semantics a little so
that the argument means something.
* source.c (list_command), symtab.c (decode_line_1): Changed call
to select_source_symtab to match new conventions.
* dbxread.c (add_file_command): This command no longer selects a
symbol table to list from.
* infrun.c (wait_for_inferior): Only call find_pc_function (to
find out if we have debugging symbols for a function and hence if
we should step over or into it) if we are doing a "step".
Thu Apr 6 12:42:28 1989 Randall Smith (randy at apple-gunkies.ai.mit.edu)
* main.c (command_line_input): Added a local buffer and only
copied information into the global main.c buffer when it is
appropriate for it to be saved (and repeated).
(dont_repeat): Only nail line when we are reading from stdin
(otherwise null lines won't repeat and what's in line needs to be
saved).
(read_command_lines): Fixed typo; you don't what to repeat when
reading command lines from the input stream unless it's standard
input.
John Gilmore's (gnu@toad.com) mods for USG gdb:
* inflow.c: Removed inclusion of sys/user.h; no longer necessary.
(, terminal_init_inferior, terminal_inferior, terminal_ours_1,
term_status_command, _initialize_inflow) Seperated out declaration
and usage of terminal mode structures based on the existence of
the individual ioctls.
* utils.c (request_quit): Restore signal handler under USG. If
running under USG initialize sys_siglist at run time (too much
variation between systems).
Wed Apr 5 13:47:24 1989 Randall Smith (randy at apple-gunkies.ai.mit.edu)
John Gilmore's (gnu@toad.com) mods for USG gdb:
* default-dep.c: Moved include of sys/user.h to after include of
a.out.h.
(store_inferior_registers): Fixed error message.
(core_file_command): Improved error messages from reading in of
u area in core file. Changed calculation of offset of registers
to account for some machines putting it in as an offset rather
than an absolute address. Changed error messages for reading of
registers from core file.
* coffread.c (read_file_hdr): Added final check for BADMAG macro
to use if couldn't recognize magic number.
* Makefile: Added explicit directions for alloca addition.
Included alloca.c in list of possible library files. Cleaned up
possible library usage. Included additional information on gcc
and include files.
* source.c, remote.c, inflow.c, dbxread.c, core.c, coffread.c:
Changed include of sys/fcntl.h to an include of fcntl.h (as per
posix; presumably this will break fewer machines. I hopw).
* README: Added a pointer to comments at top of Makefile.
* Makefile: Added a comment about machines which need fcntl.h in
sys.
Tue Apr 4 11:29:04 1989 Randall Smith (randy at apple-gunkies.ai.mit.edu)
* valprint.c (set_prettyprint_command, set_unionprint_command,
format_info): Created.
(_initialize_valprint): Added to lists of commands.
* gdb.texinfo [Backtrace]: Added a section describing the format
if symbols have not yet been read in.
* valprint.c (val_print): Added code to prettyprint structures if
"prettyprint" is set and only to print unions below the top level
if "unionprint" is set.
* infcmd.c (registers_info), valprint.c (value_print, val_print):
Added argument to call to val_print indicating deptch of recursion.
* symtab.[ch] (find_pc_psymbol): Created; finds static function
psymbol with value nearest to but under value passed.
* stack.c (print_frame_info): Used above to make sure I have best
fit to pc value.
* symseg.h (struct partial_symbol): Added value field.
* dbxread.c (read_dbx_symtab): Set value field for partial symbols
saved (so that we can lookup static symbols).
* symtab.[ch] (find_pc_symtab): Changed to external.
* stack.c (select_frame): Call above to make sure that symbols for
a selected frame is readin.
Mon Apr 3 12:48:16 1989 Randall Smith (randy at plantaris.ai.mit.edu)
* stack.c (print_frame_info): Modified to only print out full
stack frame info on symbols whose tables have been read in.
* symtab.c, symtab.h (find_pc_psymtab): Made function external;
above needed it.
* main.c (,set_verbose_command, initialize_main): Created a
variable "info_verbose" which says to talk it up in various and
sundry places. Added command to set this variable.
* gdb.texinfo (GDB Output): Added documentation on "set verbose"
and changed the name of the "Screen Output" section to "GDB
Output".
* dbxread.c (psymtab_to_symtab): Added information message about
symbol readin. Conditionalized on above.
* dbxread.c (define_symbol): Made an "i" constant be of class
LOC_CONST and an "r" constant be of class LOC_CONST_BYTES.
* README: Made a note about modifications which may be necessary
to the manual for this version of gdb.
* blockframe.c (get_prev_frame_info): Now we get saved address and
check for validity before we check for leafism. This means that
we will catch the fact that we are in start, but we will miss any
fns that start calls without an fp. This should be fine.
* m-*.h (FRAME_CHAIN): Modified to return 0 if we are in start.
This is usually a test for within the first object file.
* m-sparc.h (FRAME_CHAIN): The test here is simply if the fp saved
off the the start sp is 0.
* blockframe.c (get_prev_frame_info): Removed check to see if we
were in start. Screws up sparc.
* m-sparc.h (FRAME_FIND_SAVED_REGISTERS): Changed test for dummy
frame to not need frame to be innermost.
* gdb.texinfo: Added section on frameless invocations of functions
and when gdb can and can't deal with this.
* stack.c (frame_info): Disallowed call if no inferior or core
file; fails gracefully if truely bad stack specfication has been
given (ie. parse_frame_specification returns 0).
Fri Mar 31 13:59:33 1989 Randall Smith (randy at apple-gunkies.ai.mit.edu)
* infrun.c (normal_stop): Changed references to "unset-env" to
"delete env".
* infcmd.c (_initialize_infcmd): Change reference to set-args in
help run to "set args".
* remote.c (getpkt): Allow immediate quit when reading from
device; it could be hung.
* coffread.c (process_coff_symbol): Modify handling of REG
parameter symbols.
Thu Mar 30 15:27:23 1989 Randall Smith (randy at apple-gunkies.ai.mit.edu)
* dbxread.c (symbol_file_command): Use malloc to allocate the
space for the string table in symbol_file_command (and setup a
cleanup for this). This allows a more graceful error failure if
there isn't any memory availible (and probably allows more memory
to be avail, depending on the machine).
Additional mods for handling GNU C++ (from Tiemann):
* dbxread.c (read_type): Added case for '#' type (method type, I
believe).
(read_struct_type): If type code is undefined, make the main
variant for the type be itself. Allow recognition of bad format
in reading of structure fields.
* eval.c (evaluate_subexp): Modify evaluation of a member of a
structure and pointer to same to make sure that the syntax is
being used correctly and that the member is being accessed correctly.
* symseg.h: Added TYPE_CODE_METHOD to enum type_code. Add a
pointer to an array of argument types to the type structure.
* symtab.c (lookout_method_type, smash_to_method_type): Created.
* symtab.h (TYPE_ARG_TYPES): Created.
* valops.c (call_function): Modified handling of methods to be the
same as handling of functions; no longer check for members.
* valprint.c (val_print, type_print_varspec_{prefix,suffix},
type_print_base): Added code to print method args correctly.
* values.c (value_virtual_fn_field): Modify access to virtual
function table.
Wed Mar 29 13:19:34 1989 Randall Smith (randy at apple-gunkies.ai.mit.edu)
* findvar.c: Special cases for REGISTER_WINDOWS: 1) Return 0 if we
are the innermost frame, and 2) return the next frame in's value
if the SP is being looked for.
* blockframe.c (get_next_frame): Created; returns the next (inner)
frame of the called frame.
* frame.h: Extern delcaration for above.
* main.c (command_line_input): Stick null at end before doing
history expansion.

* symtab.c (make_symbol_completion_list): Completely rewrote to
never call psymtab_to_symtab, to do a correct search (no
duplicates) through the visible symbols, and to include structure
and union fields in the things that it can match.
Thu Mar 23 15:27:44 1989 Randall Smith (randy at apple-gunkies.ai.mit.edu)
* dbxread.c (dbx_create_type): Created; allocates and inits space

contents.
* blockframe.c (get_prev_frame_info): Added to fatal error message
to indicate that it should never happen.
* stack.c (frame_info): Printed out value of "saved" sp seperately
to call attention to the fact that it isn't stored in memory
anywhere; the actual previous frames address is printed.
* m-sparc.h (FRAME_FIND_SAVED_REGS): Set address of sp saved in
frame to value of fp (rather than value of sp in current frame).
* expread.y: Allow "unsigned" as a type itself, as well as a type
modifier.

Fri Mar 3 00:31:27 1989 Randall Smith (randy at gluteus.ai.mit.edu)
* remote.c (remote_open): Cast return from signal to (void (*)) to
avoid problems on machines where the return type of signal is (int
(*)).
* Makefile: Removed deletion of version control from it (users
will need it for their changes).

even number regs.
(fetch_inferior_registers): Get the floating point regs also.
* xgdb.c (do_command): Copied command before calling execute
command (so that execute_command wouldn't write into text space).

given COPYING as input).
* Makefile: Used above to create copying.c.
* main.c: Took out info_warranty and info_copying.

License (includes necessary changes to manual).
* xgdb.c (create_text_widget): Created text_widget before I create
the source and sink.
(print_prompt): Added fflush (stdout).

the old one there incase people still had R2.
* README: Added note about -gg format.
* remote.c (getpkt): Fixed typo; && ==> &.
* Makefile: Added new variable READLINE_FLAGS so that I could
force compilation of readline.c and history.c with -DSYSV on
system V machines. Mentioned in Makefile comments at top.
Wed Mar 1 17:01:01 1989 Randall Smith (randy at gluteus.ai.mit.edu)
* hp9k320-dep.c (store_inferior_registers): Fixed typo.

fetch_inferior_registers): Added support for remote debugging.
* remote.c (remote_timer): Created.
(remote_open, readchar): Setup to timeout reads if they take
longer than "timeout". This allows one to debug how long such
things take.
(putpkt): Modified to print a debugging message (if such things
are enabled) each time it resends a packet.
(getpkt): Modified to make the variable CSUM unsigned and read it
CSUM with an & 0xff (presumably to deal with poor sign extension
on some machines). Also made c1 and c2 unsigned.
(remote_wait): Changed buffer to unsigned status.
(remote_store_registers, remote_write_bytes): Puts a null byte at
the end of the control string.
* infcmd.c (attach_command, detach_command, _initialize_infcmd):
Made attach_command and detach_command always availible, but
modified them to only allow device file attaches if ATTACH_DETACH
is not defined.

Contributed by Jay Vosburgh (jay@mentor.cc.purdue.edu)
* m-symmetry.h, symmetry-dep.c: Created.
* Makefile: Added above in appropriate lists.
* config.gdb: Added "symmetry" target.
* utils.c (prompt_for_continue): Zero'd chars_printed also.
* utils.c (fprintf_filtered): Call prompt for continue instead of
doing it yourself.
* dbxread.c (read_dbx_symtab): Added code to conditionalize what
symbol type holds to "x.o" or "-lx" symbol that indicates the
beginning of a new file.
Tue Feb 21 16:22:13 1989 Randall Smith (randy at apple-gunkies.ai.mit.edu)
* gdb.texinfo: Deleted @ignore block at end of file.
* findvar.c, stack.c: Changed comments that refered to "frame
address" to "frame id".
* findvar.c (locate_var_value): Modified so that taking the
address of an array generates an object whose type is a pointer to
the elements of the array.
Sat Feb 18 16:35:14 1989 Randall Smith (randy at apple-gunkies.ai.mit.edu)
* gdb.texinfo: Removed reference to "!" as a shell escape
character. Added a section on controling screen output
(pagination); changing "Input" section to "User Interface"
section. Changed many inappropriate subsubsection nodes into
subsections nodes (in the readline and history expansion
sections).
Fri Feb 17 11:10:54 1989 Randall Smith (randy at apple-gunkies.ai.mit.edu)
* utils.c (set_screensize_command): Created.
(_initialize_utils): Added above to setlist.
* main.c (main): Added check to see if ~/.gdbinit and .gdbinit
were the same file; only one gets read if so. Had to include
sys/stat.h for this.
* valprint.c (type_print_base): Changed calls to print_spaces to
print_spaces_filtered.
* main.c (command_line_input): Chaned test for command line
editing to check for stdin and isatty.
* main.c (command_loop): Call reinitialize_more_filter before each
command (if reading from stdin and it's a tty).
utils.c (initialize_more_filter): Changed name to
reinitialize_more_filter; killed arguments.
utils.c (_initialize_utils): Created; initialized lines_per_page
and chars_per_line here.
* utils.c (fprintf_filtered): Removed printing of "\\\n" after
printing linesize - 1 chars; assume that the screen display will
take care of that. Still watching that overflow.
* main.c: Created the global variables linesize and pagesize to
describe the number of chars per line and lines per page.
Thu Feb 16 17:27:43 1989 Randall Smith (randy at gluteus.ai.mit.edu)
* printcmd.c (do_examine, print_scalar_formatted, print_address,
whatis_command, do_one_display, ptype_command), valprint.c
(value_print, val_print, type_print_method_args, type_print_1,
type_print_derivation_info, type_print_varspec_suffix,
type_print_base), breakpoint.c (breakpoints_info, breakpoint_1),
values.c (history_info), main.c (editing_info, warranty_info,
copying_info), infcmd.c (registers_info), inflow.c
(term_status_command), infrun.c (signals_info), stack.c

with calls to [f]printf_filtered to handle more processing.
Killed local more emulations where I noticed them.
Wed Feb 15 15:27:36 1989 Randall Smith (randy at gluteus.ai.mit.edu)
* defs.h, utils.c (initialize_more_filter, fprintf_filtered,
printf_filtered): Created a printf that will also act as a more
filter, prompting the user for a <return> whenever the page length
is overflowed.
* symtab.c (list_symbols): Elminated some code inside of an #if 0.
Tue Feb 14 11:11:24 1989 Randall Smith (randy at gluteus.ai.mit.edu)
* Makefile: Turned off backup versions for this file; it changes
too often.
* command.c (lookup_cmd, _initialize_command): Changed '!' so that
it was no longer a shell escape. "sh" must be used.
* main.c (command_line_input, set_history_expansion,
initialize_main): Turned history expansion on, made it the
default, and only execute it if the first character in the line is
a '!'.
* version.c, gdb.texinfo: Moved version to 3.2 (as usual, jumping
the gun some time before release).
* gdb.texinfo: Added sections (adapted from Brian's notes) on
command line editing and history expansion.
* main.c (set_command_editing, initialize_main): Modified name to
set_editing and modified command to "set editing".
* Makefile: Put in dependencies for READLINEOBJS.
* main.c (history_info, command_info): Combined into new command
info; deleted history_info.
(initialize_main): Deleted "info history" command; it was
interfering with the value history.
* coffread.c (enter_linenos): Modified to do bit copy instead of
pointer dereference, since the clipper machine can't handle having
longs on short boundaries.
(read_file_hdr): Added code to get number of syms for clipper.
* stack.c (return_command): Fixed method for checking when all of
the necessary frames had been popped.
* dbxread.c (read_dbx_symtab (ADD_PSYMBOL_TO_LIST)): Fixed typo in
allocation length.
Mon Feb 13 10:03:27 1989 Randall Smith (randy at gluteus.ai.mit.edu)
* dbxread.c (read_dbx_symtab): Split assignment to namestring into
several different assignments (so that it wouldn't be done except
when it had to be). Shortened switches and duplicated code to
produce the lowest possible execution time. Commented (at top of
switch) which code I duplicated.
* dbxread.c (read_dbx_symtab): Modified which variables were
register and deleted several variables which weren't used. Also
eliminated 'F' choice from subswitch, broke out strcmp's, reversed
compare on line 1986, and elminated test for !namestring[0]; it is
caught by following test for null index of ':'.
Sun Feb 12 12:57:56 1989 Randall Smith (randy at plantaris.ai.mit.edu)
* main.c (gdb_completer_word_break_characters): Turned \~ into ~.
Sat Feb 11 15:39:06 1989 Randall Smith (randy at plantaris.ai.mit.edu)
* symtab.c (find_pc_psymtab): Created; checks all psymtab's till
it finds pc.
(find_pc_symtab): Used; fatal error if psymtab found is readin
(should have been caught in symtab loop).
(lookup_symbol): Added check before scan through partial symtab
list for symbol name to be on the misc function vector (only if in
VAR_NAMESPACE). Also made sure that psymtab's weren't fooled with
if they had already been read in.
(list_symbols): Checked through misc_function_vector for matching
names if we were looking for functions.
(make_symbol_completion_list): Checked through
misc_function_vector for matching names.
* dbxread.c (read_dbx_symtab): Don't bother to do processing on
global function types; this will be taken care of by the
misc_function hack.
* symtab.h: Modified comment on misc_function structure.
Fri Feb 10 18:09:33 1989 Randall Smith (randy at plantaris.ai.mit.edu)
* symseg.h, dbxread.c (read_dbx_symtab, init_psymbol_list,
start_psymtab, end_psymtab), coffread.c (_initialize_coff),
symtab.c (lookup_partial_symbol, list_symbols,
make_symbol_completion_list): Changed separate variables for
description of partial symbol allocation into a specific kind of
structure.
(read_dbx_symtab, process_symbol_for_psymtab): Moved most of
process_symbol_for_psymtab up into read_dbx_symtab, moved a couple
of symbol types down to the ingore section, streamlined (I hope)
code some, modularized access to psymbol lists.
Thu Feb 9 13:21:19 1989 Randall Smith (randy at apple-gunkies.ai.mit.edu)
* main.c (command_line_input): Made sure that it could recognize
newlines as indications to repeat the last line.
* symtab.c (_initialize_symtab): Changed size of builtin_type_void
to be 1 for compatibility with gcc.
* main.c (initialize_main): Made history_expansion the default
when gdb is compiled with HISTORY_EXPANSION.
* readline.c, readline.h, history.c, history.h, general.h,
emacs_keymap.c, vi_keymap.c, keymaps.c, funmap.c: Made all of
these links to /gp/gnu/bash/* to keep them updated.
* main.c (initialize_main): Made default be command editing on.
Wed Feb 8 13:32:04 1989 & Smith (randy at hobbes)

* main.c: Added command lists sethistlist and unsethistlist to
accesible command lists.
(parse_binary_operation): Created to parse a on/1/yes vs. off/0/no
spec.

set_history_write, set_history_size, set_history_filename,
command_info, history_info): Created to allow users to control
various aspects of command line editing.
* main.c (symbol_creation_function): Created.
(command_line_input, initialize_main): Added rest of stuff
necessary for calling bfox' command editing routines under
run-time control.
* Makefile: Included readline and history source files for command
editing; also made arrangements to make sure that the termcap
library was available.
* symtab.c (make_symbol_completion_list): Created.
Mon Feb 6 16:25:25 1989 Randall Smith (randy at apple-gunkies.ai.mit.edu)

values in initialize_main.
* infcmd.c (registers_info), infrun.c (signals_info),
* main.c (gdb_read_line): Changed name to command_line_input.
(readline): Changed name to gdb_readline; added second argument
indicating that the read value shouldn't be saved (via malloc).

(copying_info), symtab.c (output_source_filename, MORE,
list_symbols): Converted to use gdb_readline in place of
gdb_read_line.
Sun Feb 5 17:34:38 1989 Randall Smith (randy at apple-gunkies.ai.mit.edu)
* blockframe.c (get_frame_saved_regs): Removed macro expansion
that had accidentally been left in the code.
Sat Feb 4 17:54:14 1989 Randall Smith (randy at apple-gunkies.ai.mit.edu)
* main.c (gdb_read_line, readline): Added function readline and
converted gdb_read_line to use it. This was a conversion to the
line at a time style of input, in preparation for full command
editing.
Fri Feb 3 12:39:03 1989 Randall Smith (randy at apple-gunkies.ai.mit.edu)
* dbxread.c (read_dbx_symtab): Call end_psymtab at the end of
read_dbx_symtab if any psymtab still needs to be completed.
* config.gdb, sun3-dep.c: Brought these into accord with the
actual sun2 status (no floating point period; sun3-dep.c unless
has os > 3.0).
* m-sun2os2.h: Deleted; not needed.
* config.gdb: Added a couple of aliases for machines in the
script.
* infrun.c: Added inclusion of aouthdr.h inside of #ifdef UMAX
because ptrace needs to know about the a.out header.

Thu Feb 2 16:27:06 1989 Randall Smith (randy at apple-gunkies.ai.mit.edu)
* *-dep.c: Deleted definition of COFF_FORMAT if AOUTHDR was
defined since 1) We *may* (recent mail message) want to define
AOUTHDR under a basically BSD system, and 2) AOUTHDR is sometimes
a typedef in coff encapsulation setups. Also removed #define's of
AOUTHDR if AOUTHDR is already defined (inside of coff format).
* core.c, dbxread.c: Removed #define's of AOUTHDR if AOUTHDR is
already defined (inside of coff format).
Tue Jan 31 12:56:01 1989 Randall Smith (randy at apple-gunkies.ai.mit.edu)
* GDB 3.1 released.
* values.c (modify_field): Changed test for endianness to assign
to integer and reference character (so that all bits would be
defined).
Mon Jan 30 11:41:21 1989 Randall Smith (randy at apple-gunkies.ai.mit.edu)
* news-dep.c: Deleted inclusion of fcntl.h; just duplicates stuff
found in sys/file.h.

COFF_FORMAT.
* config.gdb: Added checks for several different operating
systems.
* coffread.c (read_struct_type): Put in a flag variable so that
one could tell when you got to the end of a structure.

to ifdef based on FPU.
* infrun.c (restore_inferior_status): Changed error message to

message reporting a bad symbol type. (scan_file_globals,
read_ofile_symtab, read_addl_syms): Data type of "type" changed to
unsigned char (which is what it is).
* i386-dep.c: Removed define of COFF_FORMAT if AOUTHDR is defined.
Removed define of a_magic to magic (taken care of by N_MAGIC).
(core_file_command): Zero'd core_aouthdr instead of setting magic
to zero.
* i386-pinsn.c: Changed jcxz == jCcxz in jump table.
(putop): Added a case for 'C'.
(OP_J): Added code to handle possible masking of PC value on
certain kinds of data.

symbol number on which error occured to error output.
Fri Jan 27 11:55:04 1989 Randall Smith (randy at apple-gunkies.ai.mit.edu)

SYMBOL_TABLE_SIZE.
* gld-pinsn.c (findframe): Added declaration of framechain() as
FRAME_ADDR.
* coffread.c (read_coff_symtab): Avoided treating typedefs as
external symbol definitions.
Wed Jan 25 14:45:43 1989 Randall Smith (randy at apple-gunkies.ai.mit.edu)
* Makefile: Removed reference to alloca.c. If they need it, they
can pull alloca.o from the gnu-emacs directory.
* version.c, gdb.texinfo: Updated version to 3.1 (jumping the gun
a bit so that I won't forget when I release).
* m-sun2.h, m-sun2os2.h, m-sun3os4.h, config.gdb: Modified code so
that default includes new sun core, ptrace, and attach-detach.
Added defaults for sun 2 os 2.
Modifications to reset stack limit back to what it used to be just
before exec. All mods inside of #ifdef SET_STACK_LIMIT_HUGE.
* main.c: Added global variable original_stack_limit.
(main): Set original_stack_limit to original stack limit.
* inflow.c: Added inclusion of necessary files and external
reference to original_stack_limit.
(create_inferior): Reset stack limit to original_stack_limit.
* dbxread.c (read_dbx_symtab): Killed PROFILE_SYMBOLS ifdef.

the executables.
Mon Jan 23 15:08:51 1989 Randall Smith (randy at plantaris.ai.mit.edu)
* gdb.texinfo: Added paragraph to summary describing languages
with which gdb can be run. Also added descriptions of the
"info-methods" and "add-file" commands.
* symseg.h: Commented a range type as having TYPE_TARGET_TYPE
pointing at the containing type for the range (often int).
* dbxread.c (read_range_type): Added code to do actual range types
if they are defined. Assumed that the length of a range type is
the length of the target type; this is a lie, but will do until
somebody gets back to me as to what these silly dbx symbols mean.
* dbxread.c (read_range_type): Added code to be more picky about
recognizing builtins as range types, to treat types defined as
subranges of themselves to be subranges of int, and to recognize
the char type idiom from dbx as a special case.
Sun Jan 22 01:00:13 1989 Randall Smith (randy at apple-gunkies.ai.mit.edu)
* m-vax.h: Removed definition of FUNCTION_HAS_FRAME_POINTER.
* blockframe.c (get_prev_frame_info): Removed default definition
and use of above. Instead conditionalized checking for leaf nodes
on FUNCTION_START_OFFSET (see comment in code).

* dbxread.c (read_range_type): Fixed assumption that integer was
always type 1.
* gdb.texinfo: Fixed spelling mistake and added a note in the
running section making it clear that users may invoke subroutines
directly from gdb.
* blockframe.c: Setup a default definition for the macro
FUNCTION_HAS_FRAME_POINTER.
(get_prev_frame_info): Used this macro instead of checking
SKIP_PROLOGUE directly.
* m-vax.h: Overroad definition; all functions on the vax have
frame pointers.
Fri Jan 20 12:25:35 1989 Randall Smith (randy at apple-gunkies.ai.mit.edu)
* core.c: Added default definition of N_MAGIC for COFF_FORMAT.
* xgdb.c: Installed a fix to keep the thing from dying when there
isn't any frame selected.
* core.c: Made a change for the UMAX system; needs a different
file included if using that core format.
* Makefile: Deleted duplicate obstack.h in dbxread.c dependency.
* munch: Modified (much simpler) to cover (I hope) all cases.
* utils.c (save_cleanups, restore_cleanups): Added functions to
allow you to push and pop the chain of cleanups to be done.
* defs.h: Declared the new functions.
* main.c (catch_errors): Made sure that the only cleanups which
would be done were the ones put on the chain *after* the current
location.
* m-*.h (FRAME_CHAIN_VALID): Removed check on pc in the current
frame being valid.
* blockframe.c (get_prev_frame_info): Made the assumption that if
a frame's pc value was within the first object file (presumed to
be /lib/crt0.o), that we shouldn't go any higher.
* infrun.c (wait_for_inferior): Do *not* execute check for stop pc
at step_resume_break if we are proceeding over a breakpoint (ie.
if trap_expected != 0).
* Makefile: Added -g to LDFLAGS.
* m-news.h (POP_FRAME) Fixed typo.
* printcmd.c (print_frame_args): Modified to print out register
params in order by .stabs entry, not by register number.
* sparc-opcode.h: Changed declaration of (struct
arith_imm_fmt).simm to be signed (as per architecture manual).
* sparc-pinsn.c (fprint_addr1, print_insn): Forced a cast to an
int, so that we really would get signed behaivior (default for sun
cc is unsigned).
* i386-dep.c (i386_get_frame_setup): Replace function with new
function provided by pace to fix bug in recognizing prologue.
Thu Jan 19 11:01:22 1989 Randall Smith (randy at plantaris.ai.mit.edu)
* infcmd.c (run_command): Changed error message to "Program not
restarted."
* value.h: Changed "frame" field in value structure to be a
FRAME_ADDR (actually CORE_ADDR) so that it could survive across
calls.
* m-sun.h (FRAME_FIND_SAVED_REGS): Fixed a typo.
* value.h: Added lval: "lval_reg_frame_relative" to indicate a
register that must be interpeted relative to a frame. Added
single entry to value structure: "frame", used to indicate which
frame a relative regnum is relative to.
* findvar.c (value_from_register): Modified to correctly setup
these fields when needed. Deleted section to fiddle with last
register copied on little endian machine; multi register
structures will always occupy an integral number of registers.
(find_saved_register): Made extern.
* values.c (allocate_value, allocate_repeat_value): Zero frame
field on creation.
* valops.c (value_assign): Added case for lval_reg_frame_relative;
copy value out, modify it, and copy it back. Desclared
find_saved_register as being external.

* value.h: Added lval_reg_partsaved to enum lval_type and
commented enum lval_type. Commented value structure.
Added "struct partial_register_saved" to value struct; added
macros to deal with structure to value.h.
* values.c (free_value): Created; special cases lval_reg_partsaved
(which has a pointer to an array which also needs to be free).
(free_all_values, clear_value_history, set_internalvar,
clear_internalvars): Modified to use free_values.

these files; they aren't needed.
* README: Added comment about bug reporting and comment about
xgdb.
* Makefile: Added note to HPUX dependent section warning about
problems if compiled with gcc and mentioning the need to add
-Ihp-include to CFLAGS if you compile on those systems. Added a
note about needing the GNU nm with compilers *of gdb* that use the
coff encapsulate feature also. * hp-include: Made symbolic link
over to /gp/gnu/binutils.

to delete in "make clean". Also changed "squeakyclean" target as
"realclean".
* findvar.c (value_from_register): Added assignment of VALUE_LVAL
to be lval_memory when that is appropriate (original code didn't
bother because it assumed that it was working with a pre lval
memoried value).
* expread.y (yylex): Changed to only return type THIS if the
symbol "$this" is defined in some block superior or equal to the
current expression context block.
Mon Jan 16 13:56:44 1989 Randall Smith (randy at apple-gunkies.ai.mit.edu)
* m-*.h (FRAME_CHAIN_VALID): On machines which check the relation
of FRAME_SAVED_PC (thisframe) to first_object_file_end (all except
gould), make sure that the pc of the current frame also passes (in
case someone stops in _start).
* findvar.c (value_of_register): Changed error message in case of
no inferior or core file.

* gdb.texinfo: Added the fact that the return value for a function
is printed if you use return.
* infrun.c (wait_for_inferior): Removed test in "Have we hit
step_resume_breakpoint" for sp values in proper orientation. Was
in there for recursive calls in functions without frame pointers
and it was screwing up calls to alloca.

a.out.encap.h.
(symbol_file_command): Do HEADER_SEEK_FD when defined.

precision of printing float value; now 6 for a float and 16 for a
double.

equal to 0 or greater or equal to NSIG or a signal number is not
provided.
* command.c (lookup_cmd): Modified to not convert command section
of command line to lower case in place (in case it isn't a
subcommand, but an argument to a command).
Fri Jan 6 17:57:34 1989 Randall Smith (randy at apple-gunkies.ai.mit.edu)
* dbxread.c: Changed "text area" to "data area" in comments on
N_SETV.

of a.out.h and stab.h.
Mon Jan 2 20:38:31 1989 Randall Smith (randy at apple-gunkies.ai.mit.edu)
* eval.c (evaluate_subexp): Binary logical operations needed to
know type to determine whether second value should be evaluated.
Modified to discover type before binup_user_defined_p branch.

lexical contexts.
(read_coff_symtab): error if context stack 0 in ".ef" else case.

%esp" case.
Sun Jan 1 14:24:35 1989 Randall Smith (randy at apple-gunkies.ai.mit.edu)
* valprint.c (val_print): Rewrote routine to print string pointed
to by char pointer; was producing incorrect results when print_max
was 0.
Fri Dec 30 12:13:35 1988 Randall Smith (randy at apple-gunkies.ai.mit.edu)
* dbxread.c (read_dbx_symtab, process_symbol_for_psymtab): Put

distribution.
Thu Dec 29 10:06:41 1988 Randall Smith (randy at apple-gunkies.ai.mit.edu)
* stack.c (set_backtrace_limit_command, backtrace_limit_info,
bactrace_command, _initialize_stack): Removed modifications for
limit on backtrace. Piping the backtrace through an interuptable
"more" emulation is a better way to do it.

* breakpoint.c (commands_command): Altered so that "commands" with
no argument would refer to the last breakpoint set.
(_initialize_breakpoint): Modified help documentation.
* infrun.c (wait_for_inferior): Removed ifdef on Sun4; now you can
single step through compiler generated sub calls and will die if
you next off of the end of a function.
* sparc-dep.c (single_step): Fixed typo; "break_insn" ==> "sizeof
break_insn".
* m-sparc.h (INIT_EXTRA_FRAME_INFO): Set the bottom of a stack
frame to be the bottom of the stack frame inner from this, if that
inner one is a leaf node.
* dbxread.c (read_dbx_symtab): Check to make sure we don't add a
psymtab to it's own dependency list.
* dbxread.c (read_dbx_symtab): Modified check for duplicate
dependencies to catch them correctly.

macros FRAME_CHAIN, FRAME_CHAIN_VALID, and FRAME_CHAIN_COMBINE to
use frame info pointers as arguments instead of frame addresses.
* m-vax.h, m-umax.h, m-sun3.h, m-sun3.h, m-sparc.h, m-pn.h,
m-npl.h, m-news.h, m-merlin.h, m-isi.h, m-hp9k320.h, m-i386.h:
Modified definitions of the above macros to suit.
* m-pn.h, m-npl.h, gould-dep.c (findframe): Modified findframe to
use a frame info argument; also fixed internals (wouldn't work
before).
* m-sparc.h: Cosmetic changes; reordered some macros and made sure
that nothing went over 80 lines.
Thu Dec 22 11:49:15 1988 Randall Smith (randy at apple-gunkies.ai.mit.edu)
* Version 3.0 released.

Tue Dec 20 18:00:45 1988 Randall Smith (randy at apple-gunkies.ai.mit.edu)
* infcmd.c (step_1): Changed behavior of "step" or "next" in a
function witout line number information. It now sets the step
range around the function (to single step out of it) using the
misc function vector, warns the user, and continues.
* symtab.c (find_pc_line): Zero "end" subsection of returned
symtab_and_line if no symtab found.
Mon Dec 19 17:44:35 1988 Randall Smith (randy at apple-gunkies.ai.mit.edu)

function prologue.
(i386_frame_find_saved_regs, i386_skip_prologue): Changed to use
i386_get_frame_setup.
Sun Dec 18 11:15:03 1988 Randall Smith (randy at apple-gunkies.ai.mit.edu)
* m-sparc.h: Deleted definition of SUN4_COMPILER_BUG; was designed
to avoid something that I consider a bug in our code, not theirs,
and which I fixed earlier. Also deleted definition of
CANNOT_USE_ARBITRARY_FRAME; no longer used anywhere.
FRAME_SPECIFICATION_DYADIC used instead.
* infrun.c (wait_for_inferior): On the sun 4, if a function
doesn't have a prologue, a next over it single steps into it.
This gets around the problem of a "call .stret4" at the end of
functions returning structures.
* m-sparc.h: Defined SUN4_COMPILER_FEATURE.
* main.c (copying_info): Seperated the last printf into two
printfs. The 386 compiler will now handle it.
* i386-pinsn.c, i386-dep.c: Moved print_387_control_word,
print_387_status_word, print_387_status, and i386_float_info to
dep.c Also included reg.h in dep.c.
Sat Dec 17 15:31:38 1988 Randall Smith (randy at gluteus.ai.mit.edu)
* main.c (source_command): Don't close instream if it's null
(indicating execution of a user-defined command).
(execute_command): Set instream to null before executing
commands and setup clean stuff to put it back on error.
* inflow.c (terminal_inferior): Went back to not checking the
ioctl returns; there are some systems when this will simply fail.
It seems that, on most of these systems, nothing bad will happen
by that failure.
* values.c (value_static_field): Fixed dereferencing of null
pointer.
* i386-dep.c (i386_follow_jump): Modified to deal with
unconditional byte offsets also.
* dbxread.c (read_type): Fixed typo in function type case of switch.

* gdb.texinfo: Added a third option under the "Cannot Insert
Breakpoints" workarounds.
* printcmd.c (display_command): Don't do the display unless there
is an active inferior; only set it.
* findvar.c (value_of_register): Added an error check for calling
this when the inferior isn't active and a core file isn't being
read.
* config.gdb: Added reminder about modifying REGEX in the
makefile for the 386.

* README: Added a couple of notes about compiling gdb with itself.
* breakpoint.c (set_momentary_breakpoint): Only takes FRAME_FP of
frame if frame is non-zero.
* printcmd.c (print_scalar_formatted): Implemented /g size for
hexadecimal format on machines without an 8 byte integer type. It
seems to be non-trivial to implement /g for other formats.
(decode_format): Allowed hexadecimal format to make it through /g
fileter.
Wed Dec 14 13:27:04 1988 Randall Smith (randy at gluteus.ai.mit.edu)
* expread.y: Converted all calls to write_exp_elt from the parser
to calls to one of write_exp_elt_{opcode, sym, longcst, dblcst,
char, type, intern}. Created all of these routines. This gets
around possible problems in passing one of these things in one ear
and getting something different out the other. Eliminated
SUN4_COMPILER_BUG ifdef's; they are now superfluous.
* symmisc.c (free_all_psymtabs): Reinited partial_symtab_list to 0.
(_initialize_symmisc): Initialized both symtab_list and
partial_symtab_list.
* dbxread.c (start_psymtab): Didn't allocate anything on

(start_psymtab, end_psymtab,
process_symbol_for_psymtab): Changed most allocation
of partial symbol stuff to be off of psymbol_obstack.
* symmisc.c (free_psymtab, free_all_psymtabs): Deleted
free_psymtab subroutine.
* symtab.h: Removed num_includes and includes from partial_symtab
structure; no longer needed now that all include files have their
own psymtab.
* dbxread.c (start_psymtab): Eliminated initialization of above.
(end_psymtab): Eliminated finalization of above; get
includes from seperate list.
(read_dbx_symtab): Moved includes from psymtab list to
their own list; included in call to end_psymtab.
* symmisc.c (free_psymtab): Don't free includes.

unions from pinsn.c to opcode.h.
* sparc-pinsn.c, sparc-dep.c (isabranch, skip_prologue): Moved
this function from pinsn.c to dep.c.
* Makefile: Put in warnings about compiling with gcc (non-ansi
include files) and compiling with shared libs on Sunos 4.0 (can't
debug something that's been compiled that way).
* sparc-pinsn.c: Put in a completely new file (provided by
Tiemann) to handle floating point disassembly, load and store
instructions, and etc. better. Made the modifications this file
(ChangeLog) list for sparc-pinsn.c again.
* symtab.c (output_source_filename): Included "more" emulation hack.
* symtab.c (output_source_filename): Initialized COLUMN to 0.
(sources_info): Modified to not print out a line for
all of the include files within a partial symtab (since
they have pst's of their own now). Also modified to
make a distinction between those pst's read in and
those not.
* infrun.c: Included void declaration of single_step() if it's
going to be used.
* sparc-dep.c (single_step): Moved function previous to use of it.
* Makefile: Took removal of expread.tab.c out of make clean entry
and put it into a new "squeakyclean" entry.

TIOCSPGRP ioctl call. Just notifies if bad.
* dbxread.c (symbol_file_command): Close was getting called twice;
once directly and once through cleanup. Killed the direct call.
Sun Dec 11 19:40:40 1988 & Smith (randy at hobbes.ai.mit.edu)

TYPE_CODE_REF case.
Sat Dec 10 16:41:07 1988 Randall Smith (randy at gluteus.ai.mit.edu)
* dbxread.c: Changed allocation of psymbols from using malloc and
realloc to using obstacks. This means they aren't realloc'd out
from under the pointers to them.
Fri Dec 9 10:33:24 1988 Randall Smith (randy at apple-gunkies.ai.mit.edu)
* sparc-dep.c inflow.c core.c expread.y command.c infrun.c
infcmd.c dbxread.c symmisc.c symtab.c printcmd.c valprint.c
values.c source.c stack.c findvar.c breakpoint.c blockframe.c

for implicit declarations).
* Makefile: Cleaned up some more.
* valops.c, m-*.h (FIX_CALL_DUMMY): Modified to take 5 arguments
as per what sparc needs (programming for a superset of needed
args).
* dbxread.c (process_symbol_for_psymtab): Modified to be slightly
more picky about what it puts on the list of things *not* to be
put on the misc function list. When/if I shift everything over to
being placed on the misc_function_list, this will go away.
* inferior.h, infrun.c: Added fields to save in inferior_status
structure.
* maketarfile: Deleted; functionality is in Makefile now.
* infrun.c (wait_for_inferior): Modified algorithm for determining
whether or not a single-step was through a subroutine call. See
comments at top of file.

macro would be checked during initial readin.
* dbxread.c (read_ofile_symtab): Added macro GCC_COMPILED_FLAG_SYMBOL
into dbxread.c to indicate what string in a local text symbol will
indicate a file compiled with gcc. Defaults to "gcc_compiled.".
Thu Dec 8 11:46:22 1988 Randall Smith (randy at apple-gunkies.ai.mit.edu)
* m-sparc.h (FRAME_FIND_SAVED_REGS): Cleaned up a little to take
advantage of the new frame cache system.
* inferior.h, infrun.c, valops.c, valops.c, infcmd.c: Changed
mechanism to save inferior status over calls to inferior (eg.
call_function); implemented save_inferior_info and
restore_inferior_info.
* blockframe.c (get_prev_frame): Simplified this by a direct call
to get_prev_frame_info.
* frame.h, stack.c, printcmd.c, m-sparc.h, sparc-dep.c: Removed
all uses of frame_id_from_addr. There are short routines like it
still in frame_saved_pc (m-sparc.h) and parse_frame_spec
(stack.c). Eventually the one in frame_saved_pc will go away.
* infcmd.c, sparc-dep.c: Implemented a new mechanism for
re-selecting the selected frame on return from a call.
* blockframe.c, stack.c, findvar.c, printcmd.c, m-*.h: Changed
all routines and macros that took a "struct frame_info" as an
argument to take a "struct frame_info *". Routines: findarg,
framechain, print_frame_args, FRAME_ARGS_ADDRESS,
FRAME_STRUCT_ARGS_ADDRESS, FRAME_LOCALS_ADDRESS, FRAME_NUM_ARGS,
FRAME_FIND_SAVED_REGS.
* frame.h, stack.c, printcmd.c, infcmd.c, findvar.c, breakpoint.c,
blockframe.c, xgdb.c, i386-pinsn.c, gld-pinsn.c, m-umax.h,
m-sun2.h, m-sun3.h, m-sparc.h, m-pn.h, m-npl.h, m-news.h,
m-merlin.h, m-isi.h, m-i386.h, m-hp9k320.h: Changed routines to
use "struct frame_info *" internally.
Wed Dec 7 12:07:54 1988 Randall Smith (randy at apple-gunkies.ai.mit.edu)
* frame.h, blockframe.c, m-sparc.h, sparc-dep.c: Changed all calls
to get_[prev_]frame_cache_item to get_[prev_]frame_info.
* blockframe.c: Elminated get_frame_cache_item and
get_prev_frame_cache_item; functionality now taken care of by
get_frame_info and get_prev_frame_info.
* blockframe.c: Put allocation on an obstack and eliminated fancy
reallocation routines, several variables, and various nasty
things.
* frame.h, stack.c, infrun.c, blockframe.c, sparc-dep.c: Changed
type FRAME to be a typedef to "struct frame_info *". Had to also
change routines that returned frame id's to return the pointer
instead of the cache index.
* infcmd.c (finish_command): Used proper method of getting from
function symbol to start of function. Was treating a symbol as a
value.
* blockframe.c, breakpoint.c, findvar.c, infcmd.c, stack.c,
xgdb.c, i386-pinsn.c, frame.h, m-hp9k320.h, m-i386.h, m-isi.h,
m-merlin.h, m-news.h, m-npl.h, m-pn.h, m-sparc.h, m-sun2.h,
m-sun3.h, m-umax.h: Changed get_frame_info and get_prev_frame_info
to return pointers instead of structures.
* blockframe.c (get_pc_function_start): Modified to go to misc
function table instead of bombing if pc was in a block without a
containing function.
* coffread.c: Dup'd descriptor passed to read_coff_symtab and
fdopen'd it so that there wouldn't be multiple closes on the same
fd. Also put (fclose, stream) on the cleanup list.
* printcmd.c, stack.c: Changed print_frame_args to take a
frame_info struct as argument instead of the address of the args
to the frame.
* m-i386.h (STORE_STRUCT_RETURN): Decremented sp by sizeof object
to store (an address) rather than 1.
* dbxread.c (read_dbx_symtab): Set first_object_file_end in
read_dbx_symtab (oops).
* coffread.c (fill_in_vptr_fieldno): Rewrote TYPE_BASECLASS as
necessary.
Tue Dec 6 13:03:43 1988 Randall Smith (randy at apple-gunkies.ai.mit.edu)
* coffread.c: Added fake support for partial_symtabs to allow
compilation and execution without there use.
* inflow.c: Added a couple of minor USG mods.
* munch: Put in appropriate conditionals so that it would work on
USG systems.
* Makefile: Made regex.* handled same as obstack.*; made sure tar
file included everything I wanted it to include (including
malloc.c).
* dbxread.c (end_psymtab): Create an entry in the
partial_symtab_list for each subfile of the .o file just read in.
This allows a "list expread.y:10" to work when we haven't read in
expread.o's symbol stuff yet.
* symtab.h, dbxread.c (psymtab_to_symtab): Recognize pst->ldsymlen
== 0 as indicating a dummy psymtab, only in existence to cause the
dependency list to be read in.
* dbxread.c (sort_symtab_syms): Elminated reversal of symbols to
make sure that register debug symbol decls always come before
parameter symbols. After mod below, this is not needed.
* symtab.c (lookup_block_symbol): Take parameter type symbols
(LOC_ARG or LOC_REGPARM) after any other symbols which match.
* dbxread.c (read_type): When defining a type in terms of some
other type and the other type is supposed to have a pointer back
to this specific kind of type (pointer, reference, or function),
check to see if *that* type has been created yet. If it has, use
it and fill in the appropriate slot with a pointer to it.
Mon Dec 5 11:25:04 1988 Randall Smith (randy at apple-gunkies.ai.mit.edu)
* symmisc.c: Eliminated existence of free_inclink_symtabs and
init_free_inclink_symtabs; they aren't called from anywhere, and
if they were they could disrupt gdb's data structure badly
(elimination of struct type's which values that stick around past
elimination of inclink symtabs).
* dbxread.c (symbol_file_command): Fixed a return pathway out of
the routine to do_cleanups before it left.
* infcmd.c (set_environment_command), gdb.texinfo: Added
capability to set environmental variable values to null.
* gdb.texinfo: Modified doc on "break" without args slightly.
Sun Dec 4 17:03:16 1988 Randall Smith (randy at gluteus.ai.mit.edu)
* dbxread.c (symbol_file_command): Added check; if there weren't
any debugging symbols in the file just read, the user is warned.
* infcmd.c: Commented set_environment_command (a little).
* createtags: Cleaned up and commented.
* Makefile: Updated dependency list and cleaned it up somewhat
(used macros, didn't make .o files depend on .c files, etc.)
Fri Dec 2 11:44:46 1988 Randall Smith (randy at apple-gunkies.ai.mit.edu)
* value.h, values.c, infcmd.c, valops.c, m-i386.h, m-sparc.h,
m-merlin.h, m-npl.h, m-pn.h, m-umax.h, m-vax.h, m-hp9k320.h,
m-isi.h, m-news.h, m-sun2.h, m-sun3.h: Cleaned up dealings with
functions returning structures. Specifically: Added a function
called using_struct_return which indicates whether the function
being called is using the structure returning conventions or it is
using the value returning conventions on that machine. Added a
macro, STORE_STRUCT_RETURN to store the address of the structure
to be copied into wherever it's supposed to go, and changed
call_function to handle all of this correctly.
* symseg.h, symtab.h, dbxread.c: Added hooks to recognize an
N_TEXT symbol with name "*gcc-compiled*" as being a flag
indicating that a file had been compiled with gcc and setting a
flag in all blocks produced during processing of that file.
Thu Dec 1 13:54:29 1988 Randall Smith (randy at apple-gunkies.ai.mit.edu)
* m-sparc.h (PUSH_DUMMY_FRAME): Saved 8 less than the current pc,
as POP_FRAME and sparc return convention restore the pc to 8 more
than the value saved.
* valops.c, printcmd.c, findvar.c, value.h: Added the routine
value_from_register, to access a specific register of a specific
frame as containing a specific type, and used it in read_var_value
and print_frame_args.
Wed Nov 30 17:39:50 1988 Randall Smith (randy at apple-gunkies.ai.mit.edu)
* dbxread.c (read_number): Will accept either the argument passed
as an ending character, or a null byte as an ending character.
* Makefile, createtags: Added entry to create tags for gdb
distribution which will make sure currently configured machine
dependent files come first in the list.
Wed Nov 23 13:27:34 1988 Randall Smith (randy at gluteus.ai.mit.edu)
* stack.c, infcmd.c, sparc-dep.c: Modified record_selected_frame
to work off of frame address.
* blockframe.c (create_new_frame, get_prev_frame_cache_item):
Added code to reset pointers within frame cache if it must be
realloc'd.
* dbxread.c (read_dbx_symtab): Added in optimization comparing
last couple of characters instead of first couple to avoid
strcmp's in read_dbx_symtab (recording extern syms in misc
functions or not). 1 call to strlen is balanced out by many fewer
calls to strcmp.
Tue Nov 22 16:40:14 1988 Randall Smith (randy at cream-of-wheat.ai.mit.edu)
* dbxread.c (read_dbx_symtab): Took out optimization for ignoring
LSYM's; was disallowing typedefs. Silly me.
* Checkpointed distribution (mostly for sending to Tiemann).
* expression.h: Added BINOP_MIN and BINOP_MAX operators for C++.
* symseg.h: Included flags for types having destructors and
constructors, and flags being defined via public and via
virtual paths. Added fields NEXT_VARIANT, N_BASECLASSES,
and BASECLASSES to this type (tr: Changed types from
having to be derived from a single baseclass to a multiple
base class).
* symtab.h: Added macros to access new fields defined in symseg.h.
Added decl for lookup_basetype_type.
* dbxread.c
(condense_addl_misc_bunches): Function added to condense the misc
function bunches added by reading in a new .o file.
(read_addl_syms): Function added to read in symbols
from a new .o file (incremental linking).
(add_file_command): Command interface function to indicate
incrmental linking of a new .o file; this now calls
read_addl_syms and condense_addl_misc_bunches.
(define_symbol): Modified code to handle types defined from base
types which were not known when the derived class was
output.
(read_struct_type): Modified to better handle description of
struct types as derived types. Possibly derived from
several different base classes. Also added new code to
mark definitions via virtual paths or via public paths.
Killed seperate code to handle classes with destructors
but without constructors and improved marking of classes
as having destructors and constructors.
* infcmd.c: Modified call to val_print (one more argument).
* symtab.c (lookup_member_type): Modified to deal with new
structure in symseg.h.
(lookup_basetype_type): Function added to find or construct a type
?derived? from the given type.
(decode_line_1): Modified to deal with new type data structures.
Modified to deal with new number of args for
decode_line_2.
(decode_line_2): Changed number of args (?why?).
(init_type): Added inits for new C++ fields from
symseg.h.
*valarith.c
(value_x_binop, value_binop): Added cases for BINOP_MIN &
BINOP_MAX.
* valops.c
(value_struct_elt, check_field, value_struct_elt_for_address):
Changed to deal with multiple possible baseclasses.
(value_of_this): Made SELECTED_FRAME an extern variable.
* valprint.c
(val_print): Added an argument DEREF_REF to dereference references
automatically, instead of printing them like pointers.
Changed number of arguments in recursive calls to itself.
Changed to deal with varibale numbers of base classes.
(value_print): Changed number of arguments to val_print. Print
type of value also if value is a reference.
(type_print_derivation_info): Added function to print out
derivation info a a type.
(type_print_base): Modified to use type_print_derivation_info and
to handle multiple baseclasses.
Mon Nov 21 10:32:07 1988 Randall Smith (randy at apple-gunkies.ai.mit.edu)
* inflow.c (term_status_command): Add trailing newline to output.
* sparc-dep.c (do_save_insn, do_restore_insn): Saved
"stop_registers" over the call for the sake of normal_stop and
run_stack_dummy.
* m-sparc.h (EXTRACT_RETURN_VALUE): Put in parenthesis to force
addition of 8 to the int pointer, not the char pointer.
* sparc-pinsn.c (print_addr1): Believe that I have gotten the
syntax right for loads and stores as adb does it.
* symtab.c (list_symbols): Turned search for match on rexegp into
a single loop.
* dbxread.c (psymtab_to_symtab): Don't read it in if it's already
been read in.
* dbxread.c (psymtab_to_symtab): Changed error to fatal in
psymtab_to_symtab.
* expread.y (parse_number): Fixed bug which treated 'l' at end of
number as '0'.
Fri Nov 18 13:57:33 1988 Randall Smith (randy at gluteus.ai.mit.edu)
* dbxread.c (read_dbx_symtab, process_symbol_for_psymtab): Was
being foolish and using pointers into an array I could realloc.
Converted these pointers into integers.
Wed Nov 16 11:43:10 1988 Randall Smith (randy at apple-gunkies.ai.mit.edu)
* m-sparc.h (POP_FRAME): Made the new frame be PC_ADJUST of the
old frame.
* i386-pinsn.c, m-hp9k320.h, m-isi.h, m-merlin.h, m-news.h,
m-npl.h, m-pn.h, m-sparc.h, m-sun2.h, m-sun3.h, m-umax.h, m-vax.h:
Modified POP_FRAME to use the current frame instead of
read_register (FP_REGNUM) and to flush_cached_frames before
setting the current frame. Also added a call to set the current
frame in those POP_FRAMEs that didn't have it.
* infrun.c (wait_for_inferior): Moved call to set_current_frame up
to guarrantee that the current frame will always be set when a
POP_FRAME is done.
* infrun.c (normal_stop): Added something to reset the pc of the
current frame (was incorrect because of DECR_PC_AFTER_BREAK).
* valprint.c (val_print): Changed to check to see if a string was
out of bounds when being printed and to indicate this if so.
* convex-dep.c (read_inferior_memory): Changed to return the value
of errno if the call failed (which will be 0 if the call
suceeded).
Tue Nov 15 10:17:15 1988 Randall Smith (randy at apple-gunkies.ai.mit.edu)
* infrun.c (wait_for_inferior): Two changes: 1) Added code to
not trigger the step breakpoint on recursive calls to functions
without frame info, and 2) Added calls to distinguish recursive
calls within a function without a frame (which next/nexti might
wish to step over) from jumps to the beginning of a function
(which it generally doesn't).
* m-sparc.h (INIT_EXTRA_FRAME_INFO): Bottom set correctly for leaf
parents.
* blockframe.c (get_prev_frame_cache_item): Put in mod to check
for a leaf node (by presence or lack of function prologue). If
there is a leaf node, it is assumed that SAVED_PC_AFTER_CALL is
valid. Otherwise, FRAME_SAVED_PC or read_pc is used.
* blockframe.c, frame.h: Did final deletion of unused routines and
commented problems with getting a pointer into the frame cache in
the frame_info structure comment.
* blockframe.c, frame.h, stack.c: Killed use of
frame_id_from_frame_info; used frame_id_from_addr instead.
* blockframe.c, frame.h, stack.c, others (oops): Combined stack
cache and frame info structures.
* blockframe.c, sparc-dep.c, stack.c: Created the function
create_new_frame and used it in place of bad calls to
frame_id_from_addr.
* blockframe.c, inflow.c, infrun.c, i386-pinsn.c, m-hp9k320.h,
m-npl.h, m-pn.h, m-sparc.h, m-sun3.h, m-vax.h, default-dep.c,
convex-dep.c, gould-dep.c, hp9k320-dep.c, news-dep.c, sparc-dep.c,
sun3-dep.c, umax-dep.c: Killed use of
set_current_Frame_by_address. Used set_current_frame
(create_new_frame...) instead.
* frame.h: Killed use of FRAME_FP_ID.
* infrun.c, blockframe.c: Killed select_frame_by_address. Used
select_frame (get_current_frame (), 0) (which was correct in all
cases that we need to worry about.
Mon Nov 14 14:19:32 1988 Randall Smith (randy at apple-gunkies.ai.mit.edu)
* frame.h, blockframe.c, stack.c, m-sparc.h, sparc-dep.c: Added
mechanisms to deal with possible specification of frames
dyadically.
Sun Nov 13 16:03:32 1988 Richard Stallman (rms at sugar-bombs.ai.mit.edu)
* ns32k-opcode.h: Add insns acbw, acbd.
Sun Nov 13 15:09:58 1988 Randall Smith (randy at apple-gunkies.ai.mit.edu)
* breakpoint.c: Changed breakpoint structure to use the address of
a given frame (constant across inferior runs) as the criteria for
stopping instead of the frame ident (which varies across inferior
calls).
Fri Nov 11 13:00:22 1988 Randall Smith (randy at apple-gunkies.ai.mit.edu)
* gld-pinsn.c (findframe): Modified to work with the new frame
id's. Actually, it looks as if this routine should be called with
an address anyway.
* findvar.c (find_saved_register): Altered bactrace loop to work
off of frames and not frame infos.
* frame.h, blockframe.c, stack.c, sparc-dep.c, m-sparc.h: Changed
FRAME from being the address of the frame to being a simple ident
which is an index into the frame_cache_item list.
* convex-dep.c, default-dep.c, gould-dep.c, hp9k320-dep.c,
i386-pinsn.c, inflow.c, infrun.c, news-dep.c, sparc-dep.c,
sun3-dep.c, umax-dep.c, m-hp9k320.h, m-npl.h, m-pn.h, m-sparc.h,
m-sun3.h, m-vax.h: Changed calls of the form set_current_frame
(read_register (FP_REGNUM)) to set_current_frame_by_address (...).
Thu Nov 10 16:57:57 1988 Randall Smith (randy at gluteus.ai.mit.edu)
* frame.h, blockframe.c, gld-pinsn.c, sparc-dep.c, stack.c,
infrun.c, findvar.c, m-sparc.h: Changed the FRAME type to be
purely an identifier, using FRAME_FP and FRAME_FP_ID to convert
back and forth between the two. The identifier is *currently*
still the frame pointer value for that frame.
Wed Nov 9 17:28:14 1988 Chris Hanson (cph at kleph)
* m-hp9k320.h (FP_REGISTER_ADDR): Redefine this to return
difference between address of given FP register, and beginning of
`struct user' that it occurs in.
* hp9k320-dep.c (core_file_command): Fix sign error in size
argument to myread. Change buffer argument to pointer; was
copying entire structure.
(fetch_inferior_registers, store_inferior_registers): Replace
occurrences of `FP_REGISTER_ADDR_DIFF' with `FP_REGISTER_ADDR'.
Flush former definition.
Wed Nov 9 12:11:37 1988 Randall Smith (randy at apple-gunkies.ai.mit.edu)
* xgdb.c: Killed include of initialize.h.
* Pulled in xgdb.c from the net.
* Checkpointed distribution (to provide to 3b2 guy).
* coffread.c, dbxread.c, symmisc.c, symtab.c, symseg.h: Changed
format of table of line number--pc mapping information. Can
handle negative pc's now.
* command.c: Deleted local copy of savestring; code in utils.c is
identical.
Tue Nov 8 11:12:16 1988 Randall Smith (randy at plantaris.ai.mit.edu)
* gdb.texinfo: Added documentation for shell escape.
Mon Nov 7 12:27:16 1988 Randall Smith (randy at sugar-bombs.ai.mit.edu)
* command.c: Added commands for shell escape.
* core.c, dbxread.c: Added ROBOTUSSIN mods.
* Checkpointed distribution.
* printcmd.c (x_command): Yanked error if there is no memory to
examine (could be looking at executable straight).
* sparc-pinsn.c (print_insn): Amount to leftshift sethi imm by is
now 10 (matches adb in output).
* printcmd.c (x_command): Don't attempt to set $_ & $__ if there
is no last_examine_value (can happen if you did an x/0).
Fri Nov 4 13:44:49 1988 Randall Smith (randy at gluteus.ai.mit.edu)
* printcmd.c (x_command): Error if there is no memory to examine.
* gdb.texinfo: Added "cont" to the command index.
* sparc-dep.c (do_save_insn): Fixed typo in shift amount.
* m68k-opcode.h: Fixed opcodes for 68881.
* breakpoint.c, infcmd.c, source.c: Changed defaults in several
places for decode_line_1 to work off of the default_breakpoint_*
values instead of current_source_* values (the current_source_*
values are off by 5 or so because of listing defaults).
* stack.c (frame_info): ifdef'd out FRAME_SPECIFCATION_DYADIC in
the stack.c module. If I can't do this right, I don't want to do
it at all. Read the comment there for more info.
Mon Oct 31 16:23:06 1988 Randall Smith (randy at gluteus.ai.mit.edu)
* gdb.texinfo: Added documentation on the "until" command.
Sat Oct 29 17:47:10 1988 Randall Smith (randy at apple-gunkies.ai.mit.edu)
* breakpoint.c, infcmd.c: Added UNTIL_COMMAND and subroutines of
it.
* breakpoint.c, infcmd.c, infrun.c: Added new field to breakpoint
structure (silent, indicating a silent breakpoint), and modified
breakpoint_stop_status and things that read it's return value to
understand it.
Fri Oct 28 17:45:33 1988 Randall Smith (randy at gluteus.ai.mit.edu)
* dbxread.c, symmisc.c: Assorted speedups for readin, including
special casing most common symbols, and doing buffering instead of
calling malloc.
Thu Oct 27 11:11:15 1988 Randall Smith (randy at gluteus.ai.mit.edu)
* stack.c, sparc-dep.c, m-sparc.h: Modified to allow "info frame"
to take two arguments on the sparc and do the right thing with
them.
* dbxread.c (read_dbx_symtab, process_symbol_for_psymtab): Put
stuff to put only symbols that didn't have debugging info on the
misc functions list back in.
Wed Oct 26 10:10:32 1988 Randall Smith (randy at gluteus.ai.mit.edu)
* valprint.c (type_print_varspec_suffix): Added check for
TYPE_LENGTH(TYPE_TARGET_TYPE(type)) > 0 to prevent divide by 0.
* printcmd.c (print_formatted): Added check for VALUE_REPEATED;
value_print needs to be called for that.
* infrun.c (wait_for_inferior): Added break when you decide to
stop on a null function prologue rather than continue stepping.
* m-sun3.h: Added explanatory comment to REGISTER_RAW_SIZE.
* expread.y (parse_c_1): Initialized paren_depth for each parse.
Tue Oct 25 14:19:38 1988 Randall Smith (randy at gluteus.ai.mit.edu)
* valprint.c, coffread.c, dbxread.c: Enum constant values in enum
type now accessed through TYPE_FIELD_BITPOS.
* dbxread.c (process_symbol_for_psymtab): Added code to deal with
possible lack of a ":" in a debugging symbol (do nothing).
* symtab.c (decode_line_1): Added check in case of all numbers for
complete lack of symbols.
* source.c (select_source_symtab): Made sure that this wouldn't
bomb on complete lack of symbols.
Mon Oct 24 12:28:29 1988 Randall Smith (randy at apple-gunkies.ai.mit.edu)
* m-sparc.h, findvar.c: Ditched REGISTER_SAVED_UNIQUELY and based
code on REGISTER_IN_WINDOW_P and HAVE_REGISTER_WINDOWS. This will
break when we find a register window machine which saves the
window registers within the context of an inferior frame.
* sparc-dep.c (frame_saved_pc): Put PC_ADJUST return back in for
frame_saved_pc. Seems correct.
* findvar.c, m-sparc.h: Created the macro REGISTER_SAVED_UNIQUELY
to handle register window issues (ie. that find_saved_register
wasn't checking the selected frame itself for shit).
* sparc-dep.c (core_file_command): Offset target of o & g register
bcopy by 1 to hit correct registers.
* m-sparc.h: Changed STACK_END_ADDR.
Sun Oct 23 19:41:51 1988 Randall Smith (randy at apple-gunkies.ai.mit.edu)
* sparc-dep.c (core_file_command): Added in code to get the i & l
registers from the stack in the corefile, and blew away some wrong
code to get i & l from inferior.
Fri Oct 21 15:09:19 1988 Randall Smith (randy at apple-gunkies.ai.mit.edu)
* m-sparc.h (PUSH_DUMMY_FRAME): Saved the value of the RP register
in the location reserved for i7 (in the created frame); this way
the rp value won't get lost. The pc (what we put into the rp in
this routine) gets saved seperately, so we loose no information.
* sparc-dep.c (do_save_insn & do_restore_insn): Added a wrapper to
preserve the proceed status state variables around each call to
proceed (the current frame was getting munged because this wasn't
being done).
* m-sparc.h (FRAME_FIND_SAVED_REGS): Fix bug: saved registers
addresses were being computed using absolute registers number,
rather than numbers relative to each group of regs.
* m-sparc.h (POP_FRAME): Fixed a bug (I hope) in the context
within which saved reg numbers were being interpetted. The
values to be restored were being gotten in the inferior frame, and
the restoring was done in the superior frame. This means that i
registers must be restored into o registers.
* sparc-dep.c (do_restore_insn): Modified to take a pc as an
argument, instead of a raw_buffer. This matches (at least it
appears to match) usage from POP_FRAME, which is the only place
from which do_restore_insn is called.
* sparc-dep.c (do_save_insn and do_restore_insn): Added comments.
* m-sparc.h (FRAME_FIND_SAVED_REGS): Modified my code to find the
save addresses of out registers to use the in regs off the stack
pointer when the current frame is 1 from the innermost.
Thu Oct 20 13:56:15 1988 & Smith (randy at hobbes.ai.mit.edu)
* blockframe.c, m-sparc.h: Removed code associated with
GET_PREV_FRAME_FROM_CACHE_ITEM. This code was not needed for the
sparc; you can always find the previous frames fp from the fp of
the current frame (which is the sp of the previous). It's getting
the information associated with a given frame (ie. saved
registers) that's a bitch, because that stuff is saved relative to
the stack pointer rather than the frame pointer.
* m-sparc.h (GET_PREV_FRAME_FROM_CACHE_ITEM): Modified to return
the frame pointer of the previous frame instead of the stack
pointer of same.
* blockframe.c (flush_cached_frames): Modified call to
obstack_free to free back to frame_cache instead of back to zero.
This leaves the obstack control structure in finite state (and
still frees the entry allocated at frame_cache).
Sat Oct 15 16:30:47 1988 & Smith (randy at tartarus.uchicago.edu)
* valops.c (call_function): Suicide material here. Fixed a typo;
CALL_DUMMY_STACK_ADJUST was spelled CAll_DUMMY_STACK_ADJUST on
line 530 of the file. This cost me three days. I'm giving up
typing for lent.
Fri Oct 14 15:10:43 1988 & Smith (randy at tartarus.uchicago.edu)
* m-sparc.h: Corrected a minor mistake in the dummy frame code
that was getting the 5th argument and the first argument from the
same place.
Tue Oct 11 11:49:33 1988 & Smith (randy at tartarus.uchicago.edu)
* infrun.c: Made stop_after_trap and stop_after_attach extern
instead of static so that code which used proceed from machine
dependent files could fiddle with them.
* blockframe.c, frame.h, sparc-dep.c, m-sparc.h: Changed sense of
->prev and ->next in struct frame_cache_item to fit usage in rest
of gdb (oops).
Mon Oct 10 15:32:42 1988 Randy Smith (randy at gargoyle.uchicago.edu)
* m-sparc.h, sparc-dep.c, blockframe.c, frame.h: Wrote
get_frame_cache_item. Modified FRAME_SAVED_PC and frame_saved_pc
to take only one argument and do the correct thing with it. Added
the two macros I recently defined in blockframe.c to m-sparc.h.
Have yet to compile this thing on a sparc, but I've now merged in
everything that I received from tiemann, either exactly, or simply
effectively.
* source.c: Added code to allocated space to sals.sals in the case
where no line was specified.
* blockframe.c, infrun.c: Modified to cache stack frames requested
to minimize accesses to subprocess.
Tue Oct 4 15:10:39 1988 Randall Smith (randy at cream-of-wheat.ai.mit.edu)
* config.gdb: Added sparc.
Mon Oct 3 23:01:22 1988 Randall Smith (randy at cream-of-wheat.ai.mit.edu)
* Makefile, blockframe.c, command.c, core.c, dbxread.c, defs.h,
expread.y, findvar.c, infcmd.c, inflow.c, infrun.c, sparc-pinsn.c,
m-sparc.h, sparc-def.c, printcmd.c, stack.c, symmisc.c, symseg.h,
valops.c, values.c: Did initial merge of sparc port. This will
not compile; have to do stack frame caching and finish port.
* inflow.c, gdb.texinfo: `tty' now resets the controling terminal.
Fri Sep 30 11:31:16 1988 Randall Smith (randy at gluteus.ai.mit.edu)
* inferior.h, infcmd.c, infrun.c: Changed the variable
stop_random_signal to stopped_by_random signal to fit in better
with name conventions (variable is not a direction to the
proceed/resume set; it is information from it).
Thu Sep 29 13:30:46 1988 Randall Smith (randy at cream-of-wheat.ai.mit.edu)
* infcmd.c (finish_command): Value type of return value is now
whatever the function returns, not the type of the function (fixed
a bug in printing said value).
* dbxread.c (read_dbx_symtab, process_symbol_for_psymtab):
Put *all* global symbols into misc_functions. This is what was
happening anyway, and we need it for find_pc_misc_function.
** This was eventually taken out, but I didn't mark it in the
ChangeLog. Oops.
* dbxread.c (process_symbol_for_psymtab): Put every debugger
symbol which survives the top case except for constants on the
symchain. This means that all of these *won't* show up in misc
functions (this will be fixed once I make sure it's broken the way
it's supposed to be).
* dbxread.c: Modified placement of debugger globals onto the hash
list; now we exclude the stuff after the colon and don't skip the
first character (debugger symbols don't have underscores).
* dbxread.c: Killed debuginfo stuff with ifdef's.
Wed Sep 28 14:31:51 1988 Randall Smith (randy at cream-of-wheat.ai.mit.edu)
* symtab.h, dbxread.c: Modified to deal with BINCL, EINCL, and
EXCL symbols produced by the sun loader by adding a list of
pre-requisite partial_symtabs that each partial symtab needs.
* symtab.h, dbxread.c, symtab.c, symmisc.c: Modified to avoid
doing a qsort on the local (static) psymbols for each file to
speed startup. This feature is not completely debugged, but it's
inclusion has forced the inclusion of another feature (dealing
with EINCL's, BINCL's and EXCL's) and so I'm going to go in and
deal with them.
* dbxread.c (process_symbol_for_psymtab): Made sure that the class
of the symbol made it into the partial_symbol entry.
Tue Sep 27 15:10:26 1988 Randall Smith (randy at gluteus.ai.mit.edu)
* dbxread.c: Fixed bug; init_psymbol_list was not being called
with the right number of arguments (1).
* dbxread.c: Put ifdef's around N_MAIN, N_M2C, and N_SCOPE to
allow compilation on a microvax.
* config.gdb: Modified so that "config.gdb vax" would work.
* dbxread.c, symtab.h, symmisc.h, symtab.c, source.c: Put in many
and varied hacks to speed up gdb startup including: A complete
rewrite of read_dbx_symtab, a modification of the partial_symtab
data type, deletion of select_source_symtab from
symbol_file_command, and optimiztion of the call to strcmp in
compare_psymbols.
Thu Sep 22 11:08:54 1988 Randall Smith (randy at gluteus.ai.mit.edu)
* dbxread.c (psymtab_to_symtab): Removed call to
init_misc_functions.
* dbxread.c: Fixed enumeration type clash (used enum instead of
integer constant).
* breakpoint.c: Fixed typo; lack of \ at end of line in middle of
string constant.
* symseg.h: Fixed typo; lack of semicolon after structure
definition.
* command.c, breakpoint.c, printcmd.c: Added cmdlist editing
functions to add commands with the abbrev flag set. Changed
help_cmd_list to recognize this flag and modified unset,
undisplay, and enable, disable, and delete breakpoints to have
this flag set.
Wed Sep 21 13:34:19 1988 Randall Smith (randy at plantaris.ai.mit.edu)
* breakpoint.c, infcmd.c, gdb.texinfo: Created "unset" as an alias
for delete, and changed "unset-environment" to be the
"environment" subcommand of "delete".
* gdb.texinfo, valprint.c: Added documentation in the manual for
breaking the set-* commands into subcommands of set. Changed "set
maximum" to "set array-max".
* main.c, printcmd.c, breakpoint.c: Moved the declaration of
command lists into main and setup a function in main initializing
them to guarrantee that they would be initialized before calling
any of the individual files initialize routines.
* command.c (lookup_cmd): A null string subcommand is treated as
an unknown subcommand rather than an ambiguous one (eg. "set $x =
1" will now work).
* infrun.c (wait_for_inferior): Put in ifdef for Sony News in
check for trap by INNER_THAN macro.
* eval.c (evaluate_subexp): Put in catch to keep the user from
attempting to call a non function as a function.
Tue Sep 20 10:35:53 1988 Randall Smith (randy at oatmeal.ai.mit.edu)
* dbxread.c (read_dbx_symtab): Installed code to keep track of
which global symbols did not have debugger symbols refering to
them, and recording these via record_misc_function.
* dbxread.c: Killed code to check for extra global symbols in the
debugger symbol table.
* printcmd.c, breakpoint.c: Modified help entries for several
commands to make sure that abbreviations were clearly marked and
that the right commands showed up in the help listings.
* main.c, command.c, breakpoint.c, infcmd.c, printcmd.c,
valprint.c, defs.h: Modified help system to allow help on a class
name to show subcommands as well as commands and help on a command
to show *all* subcommands of that command.
Fri Sep 16 16:51:19 1988 Randall Smith (randy at gluteus.ai.mit.edu)
* breakpoint.c (_initialize_breakpoint): Made "breakpoints"
subcommands of enable, disable, and delete use class 0 (ie. they
show up when you do a help xxx now).
* infcmd.c,printcmd,c,main.c,valprint.c: Changed the set-*
commands into subcommands of set. Created "set variable" for use
with variables whose names might conflict with other subcommands.
* blockframe.c, dbxread.c, coffread.c, expread.y, source.c:
Fixed mostly minor (and one major one in block_for_pc) bugs
involving checking the partial_symtab_list when a scan through the
symtab_list fails.
Wed Sep 14 12:02:05 1988 Randall Smith (randy at sugar-smacks.ai.mit.edu)
* breakpoint.c, gdb.texinfo: Added enable breakpoints, disable
breakpoints and delete breakpoints as synonyms for enable,
disable, and delete. This seemed reasonable because of the
immeninent arrival of watchpoints & etc.
* gdb.texinfo: Added enable display, disable display, and delete
display to manual.
Tue Sep 13 16:53:56 1988 Randall Smith (randy at sugar-smacks.ai.mit.edu)
* inferior.h, infrun.c, infcmd.c: Added variable
stop_random_signal to indicate when a proceed had been stopped by
an unexpected signal. Used this to determine (in normal_stop)
whether the current display point should be deleted.
* valops.c: Fix to value_ind to check for reference before doing a
COERCE_ARRAY.
Sun Jul 31 11:42:36 1988 Richard Stallman (rms at frosted-flakes.ai.mit.edu)
* breakpoint.c (_initialize_breakpoint): Clean up doc for commands
that can now apply also to auto-displays.
* coffread.c (record_line): Corrected a spazz in editing.
Also removed the two lines that assume line-numbers appear
only in increasing order.
Tue Jul 26 22:19:06 1988 Peter TerMaat (pete at corn-chex.ai.mit.edu)
* expression.h, eval.c, expprint.c, printcmd.c, valarith.c,
valops.c, valprint.c, values.c, m-*.h: Changes for evaluating and
displaying 64-bit `long long' integers. Each machine must define
a LONGEST type, and a BUILTIN_TYPE_LONGEST.
* symmisc.c: (print_symtab) check the status of the fopen and call
perror_with_name if needed.
Thu Jul 21 00:56:11 1988 Peter TerMaat (pete at corn-chex.ai.mit.edu)
* Convex: core.c: changes required by Convex's SOFF format were
isolated in convex-dep.c.
Wed Jul 20 21:26:10 1988 Peter TerMaat (pete at corn-chex.ai.mit.edu)
* coffread.c, core.c, expread.y, i386-pinsn.c, infcmd.c, inflow.c,
infrun.c, m-i386.h, main.c, remote.c, source.c, valops.c:
Improvements for the handling of the i386 and other machines
running USG. (Several of these files just needed extra header files
such as types.h.) utils.c: added bcopy, bcmp, bzero, getwd, list
of signals, and queue routines for USG systems. Added vfork macro
to i386
* printcmd.c, breakpoint.c: New commands to enable/disable
auto-displays. Also `delete display displaynumber' works like
`undisplay displaynumber'.
Tue Jul 19 02:17:18 1988 Peter TerMaat (pete at corn-chex.ai.mit.edu)
* coffread.c: (coff_lookup_type) Wrong portion of type_vector was
being bzero'd after type_vector was reallocated.
* printcmd.c: (delete_display) Check for a display chain before
attempting to delete a display.
* core.c, *-dep.c (*-infdep moved to *-dep): machine-dependent
parts of core.c (core_file_command, exec_file_command) moved to
*-dep.c.
Mon Jul 18 19:45:51 1988 Peter TerMaat (pete at corn-chex.ai.mit.edu)
* dbxread.c: typo in read_struct_type (missing '=') was causing a
C struct to be parsed as a C++ struct, resulting in a `invalid
character' message.
Sun Jul 17 22:27:32 1988 Peter TerMaat (pete at corn-chex.ai.mit.edu)
* printcmd.c, symtab.c, valops.c, expread.y: When an expression is
read, the innermost block required to evaluate the expression is
saved in the global variable `innermost_block'. This information
is saved in the `block' field of an auto-display so that
expressions with inactive variables can be skipped. `info display'
tells the user which displays are active and which are not. New
fn `contained_in' returns nonzero if one block is contained within
another.
Fri Jul 15 01:53:14 1988 Peter TerMaat (pete at corn-chex.ai.mit.edu)
* infrun.c, m-i386.h: Use macro TRAPS_EXPECTED to set number of
traps to skip when sh execs the program. Default is 2, m-i386.h
overrides this and sets to 4.
* coffread.c, infrun.c: minor changes for the i386. May be able
to eliminate them with more general code.
* default-infdep.c: #ifdef SYSTEMV, include header file types.h.
Also switched the order of signal.h and user.h, since System 5
requires signal.h to come first.
* core.c main.c, remote,c, source.c, inflow.c: #ifdef SYSTEMV,
include various header files. Usually types.h and fcntl.h.
* utils.c: added queue routines needed by the i386 (and other sys
5 machines).
* sys5.c, regex.c, regex.h: new files for sys 5 systems. (The
regex files are simply links to /gp/gnu/lib.)
Thu Jul 14 01:47:14 1988 Peter TerMaat (pete at corn-chex.ai.mit.edu)
* config.gdb, README: Provide a list of known machines when user
enters an invalid machine. New second arg is operating system,
currently only used with `sunos4' or `os4'. Entry for i386 added.
* news-infdep.c: new file.
* m-news.h: new version which deals with new bugs in news800's OS.
Tue Jul 12 19:52:16 1988 Peter TerMaat (pete at corn-chex.ai.mit.edu)
* Makefile, *.c, munch, config.gdb, README: New initialization
scheme uses nm to find functions whose names begin with
`_initialize_'. Files `initialize.h', `firstfile.c',
`lastfile.c', `m-*init.h' no longer needed.
* eval.c, symtab.c, valarith.c, valops.c, value.h, values.c: Bug
fixes from gdb+ 2.5.4. evaluate_subexp takes a new arg, type
expected. New fn value_virtual_fn_field.
Mon Jul 11 00:48:49 1988 Peter TerMaat (pete at corn-chex.ai.mit.edu)
* core.c (read_memory): xfer_core_file was being called with an
extra argument (0) by read_memory.
* core.c (read_memory), *-infdep.c (read_inferior_memory),
valops.c (value_at): read_memory and read_inferior_memory now work
like write_memory and write_inferior_memory in that errno is
checked after each ptrace and returned to the caller. Used in
value_at to detect references to addresses which are out of
bounds. Also core.c (xfer_core_file): return 1 if invalid
address, 0 otherwise.
* inflow.c, <machine>-infdep.c: removed all calls to ptrace from
inflow.c and put them in machine-dependent files *-infdep.c.
Sun Jul 10 19:19:36 1988 Peter TerMaat (pete at corn-chex.ai.mit.edu)
* symmisc.c: (read_symsegs) Accept only format number 2. Since
the size of the type structure changed when C++ support was added,
format 1 can no longer be used.
* core.c, m-sunos4.h: (core_file_command) support for SunOS 4.0.
Slight change in the core structure. #ifdef SUNOS4. New file
m-sunos4.h. May want to change config.gdb also.
Fri Jul 8 19:59:49 1988 Peter TerMaat (pete at corn-chex.ai.mit.edu)
* breakpoint.c: (break_command_1) Allow `break if condition'
rather than parsing `if' as a function name and returning an
error.
Thu Jul 7 22:22:47 1988 Peter TerMaat (pete at corn-chex.ai.mit.edu)
* C++: valops.c, valprint.c, value.h, values.c: merged code to deal
with C++ expressions.
Wed Jul 6 03:28:18 1988 Peter TerMaat (pete at corn-chex.ai.mit.edu)
* C++: dbxread.c: (read_dbx_symtab, condense_misc_bunches,
add_file_command) Merged code to read symbol information from
an incrementally linked file. symmisc.c:
(init_free_inclink_symtabs, free_inclink_symtabs) Cleanup
routines.
Tue Jul 5 02:50:41 1988 Peter TerMaat (pete at corn-chex.ai.mit.edu)
* C++: symtab.c, breakpoint.c, source.c: Merged code to deal with
ambiguous line specifications. In C++ one can have overloaded
function names, so that `list classname::overloadedfuncname'
refers to several different lines, possibly in different files.
Fri Jul 1 02:44:20 1988 Peter TerMaat (pete at corn-chex.ai.mit.edu)
* C++: symtab.c: replaced lookup_symtab_1 and lookup_symtab_2 with
a modified lookup_symbol which checks for fields of the current
implied argument `this'. printcmd.c, source.c, symtab.c,
valops.c: Need to change callers once callers are
installed.
Wed Jun 29 01:26:56 1988 Peter TerMaat (pete at frosted-flakes.ai.mit.edu)
* C++: eval.c, expprint.c, expread.y, expression.h, valarith.c,
Merged code to deal with evaluation of user-defined operators,
member functions, and virtual functions.
binop_must_be_user_defined tests for user-defined binops,
value_x_binop calls the appropriate operator function.
Tue Jun 28 02:56:42 1988 Peter TerMaat (pete at frosted-flakes.ai.mit.edu)
* C++: Makefile: changed the echo: expect 101 shift/reduce conflicts
and 1 reduce/reduce conflict.
