through the target vector.
* inferior.h (kill_inferior_fast): remove declaration.

* m68k-pinsn (print_insn_arg, fetch_arg): added support for
operands to memory management instructions, from WRS.
Replace with simple default to C before processing any init

be consistent in setting a default language if none has been
previously set.

(FRAME_SPECIFICATION_DYADIC): Ask for two args in frame command.
Briefly explain MIPS stacks in GDB.
Rich and I believe the "real problem" was that both single_step
and target_resume were issuing PT_CONTINUE calls. This would
cause the second PT_CONTINUE to sometimes fail because the process
was already running.
* infptrace.c (child_resume): Remove AIX_BUGGY_PTRACE_CALL kludge.
* infptrace.c (child_resume): Don't deal with NO_SINGLE_STEP

messages properly!!
(getpty (NCR)): Lotsa bug fixes...
(kernel_dispatch (case StopRType)): Use kill() instead of
killpg() so we can deal with losing systems...

zero out readfds when select() returns zero.
(energize_initialize): Use I_SETSIG to get SIGIO interrupts. Use
getcwd() instead of getwd() (NCR getwd() seg faults).
(energize_wait): Use sigaction() for NCR. Their version of signal()
is unreliable by default.
places where we must notify kernel of where the given pc is.

* config/sun4.{mh,mt}: Remove (use identical sun4os4.*).
sub-variants of SunOS, e.g. sunos4* to match sunos4.1.1.

followed by pointer into string being demangled, followed by
pointer to the string where the result is being stored, followed
by other args. Also generally replace most variables of name

* symtab.c (lookup_symbol, lookup_demangled_block_symbol,
lookup_demangled_partial_symbol,): Ask demangle_and_match to

and use it to decide when to print the actual type name rather than
trying to invent the name of a fundamental type. This clears up the
confusion between int/long when they are the same sizes, removes one
obstacle to multi-language support (previously valprint.c thought
everything was a C type), and allows gdb to support distinctions between
explicitly and implicitly signed types when the compiler supports such
distinction in the debug output (as does every ANSI compiler I tested
except for gcc).

gdb/config/mh-irix4 texinfo/configure.in: Port to SGI Irix-4.x.
Actually, just pick up a couple of files that I forgot.
* defs.h: Reword confusing comment about ANSI prototypes.
* defs.h: Some minor whitespace changes.
* infrun.c (wait_for_inferior): Compare int tmp to int 0,
not NULL, which can be (void *).
* tm-amix.h, tm-i386v4.h: Add defines for setjmp/longjmp handling.
* tm-i386v.h (SP_ARG0): Define
* xm-sysv4.h: Back out of change for missing prototypes.
* i386-tdep.c (get_longjmp_target): Add function.
* All GDB files that #include defs.h: Removed stdio.h.
(defs.h): #include stdio.h.
This has been tested by building GDBs for all targets hosted on Sun4.
None of the build problems were related to stdio.h inclusion. (n.b.
many configurations don't build for other reasons.)
a ptype to reflect the setting of TARGET_PTR_BIT. Set the
TYPE_FLAGS of a ptype to TYPE_FLAG_UNSIGNED.
* tm-h8300.h, h8300-tdep.c, remote-hms.c: personal checkpoint
* printcmd.c (print_address): if ADDR_BITS_REMOVE is defined, use
it before printing out the hex shape of an address.
functions for which no definitions or prototypes are provided in
any currently included gdb or host environment header files.
For SVR4, this currently includes malloc and realloc, which cannot
be portably prototyped in any gdb include file.
size, and use throughout. Round buffer size up if too many regs.
Support baud rate setting and try for an 8-bit path. If
interrupted while waiting for target, send a ^C down the wire.
Avoid single-byte reads.
* tm-mips.h: Add more embedded-system registers to REGISTER_NAMES
and NUM_REGS.
* mips-xdep.h: Avoid the embedded regs when on Unix.
all-breakpoints' command.
* (get_number): Allow users to enter negative breakpoint numbers.
* (breakpoint_1): Reformat display of 'info break' to show new
fields.
* (create_longjmp_breakpoint, breakpoint_re_set,
breakpoint_re_set_one, enable/disable_longjmp_breakpoint),
symfile.c (syms_from_objfile): Re-do
insertion of longjmp breakpoints. Move all code into
breakpoint_re_set, and call that instead of
create_longjmp_breakpoint in symfile.c.
* breakpoint.c (breakpoint_re_set): Use ALL_BREAKPOINTS_SAFE.
* symtab.c (find_pc_symtab): Handle having no objfiles.
* infcmd.c: Fix comment.
* objfiles.c (free_all_objfiles): Add.
* symfile.h (ALL_OBJFILES, ALL_OBJFILES_SAFE): Add.
* symfile.c (symbol_file_command): free all objfiles when
specifying a new symbol file.
(reread_symbols): Stat the file name, don't fstat the descriptor.
* breakpoint.h: Move prototypes to follow enum definition they need.
* breakpoint.c, infrun.c: Lint.
* printcmd.c: Use `enum enable' rather than `enum
display_status'.
* mipsread.c: First pass at making it compile with the new
objfile changes. Probably seriously broken still, but it
compiles. FIXME.
breakpoint.h, tm-sun4os4.h, tm-sparc.h, sparc-tdep.c, tm-mips.h,
mips-tdep.h, tm-sun3.h, tm-68k.h, m68k-tdep.h: Add support for
stepping (and nexting) through longjmp(). Also, cleanup
breakpoint handling quite a bit by creating explicit breakpoint
types instead of using magic breakpoint numbers.
Makefile.in: Update version to 4.4.3
* minsyms.c (install_minimal_symbols): Add bunches to any
existing minsyms in the objfile. Avoid extra mallocation
by working directly in the obstack. Remove ignored `mainline' parm.
* coffread.c, dbxread.c, elfread.c, mipsread.c, solib.c, symtab.h,
xcoffread.c: Change all callers.
* FIXME: We should be able to eliminate MAINLINE from all the
symbol readers now, with a small bit of work.
* valops.c, value.h: Lint.
* remote-vx.c: Add missing break; statement. Bugfix by
Michael Sclafani, <sclafani@src.dec.com>.
to make prototypes for all functions declared here.
* cplus-dem.c: Avoid declaring xmalloc and xrealloc.
* c-exp.y: Rename SIGNED, OR, and AND to avoid conflict.
* environ.c: Include <stdio.h> before defs.h. Minor cleanup.
* ieee-float.h: Use PARAMS for prototypes; make some params const.
* ieee-float.c, valarith.c: Include <stdio.h>. Lint. b*=>mem*.
* m2-exp.y: Remove unused CONST; Rename OR and AND.
* utils.c: Avoid declaring malloc and realloc. Lint.
(request_quit): Accept signal-number parameter.
symbol table and add symbol information to the misc function vector.
This allows minimum functionality with non -g compiled code, and is
vital for use with shared libraries (non of which are currently
compiled with -g).
Note to anyone doing any SVR4/gdb work. This bug was introduced into
gdb just prior to the gdb 4.4 release, thus any versions currently
in the field will have broken shared library support since no symbol
information at all will be available for the shared library. This
fix, along with one about to go into bfd's elf.c should fix that
problem.
between partial symbol tables (when not doing stabs-in-ecoff).
(This used to be handled by parse_fdr, but parse_fdr was
incompatible with handling stabs-in-ecoff, so the code
was re-written to not use parse_fdr. Unfortunately,
the logic to handle dependencies was overlooked.)
describing enum.
* defs.h: added new #define for TARGET_PTR_BIT, defaults to size
of target int.
* h8300-tdep.c, remote-hms.c, tm-h8300.h: too many changes to count
* symtab.c (lookup_reference_type, lookup_ptr_type): use
TARGET_PTR_BIT to determine size of a pointer
* values.c (unpack_long): when unpacking a REF or a PTR don't
assume the size of the type.
* dbxread.c (read_ofile_symtab): Fix up N_CATCH better. Pass
offset to process_one_symbol.
(process_one_symbol): Take new offset parameter. Add it into
appropriate symbol types to relocate symbols to loaded addresses.
Handle all possible symbol types, and complain() about types that
we don't expect to see.
* mipsread.c (psymtab_to_symtab_1): Pass offset of zero to
process_one_symbol (FIXME, should pass real offset).
Misc bugfixes:
* breakpoint.c (resolve_sal_pc): Split out code to resolve a
sal's PC value.
(set_breakpoint, break_command_1, until_break_command,
catch_command_1, breakpoint_re_set_one): Use it.
(breakpoint_re_set_one): Disable bkpts that don't re-set cleanly.
(breakpoint_re_set): Mention breakpoint number in error messages.
* symtab.h (resolve_sal_pc): Declare.
* infcmd.c (jump_command): Use resolve_sal_pc.
* source.c (find_source_lines): Avoid "Source file is more
recent than executable" when bfd_get_mtime gives 0.
(list_command): Shorten "FILE, line N" to "FILE:N".
* putenv.c (putenv): Avoid unportably casting pointers to unsigneds.
* target.c (target_read_string): Create this routine to read null
terminated strings from the target. It deals with running off the
end of memory elegantly as well. solib.c (find_solib): Use
target_read_string() to avoid problems with running off the end of
memory.
to xm-sysv4.h. Split OPCODE_DIR into OPCODE_DIR1 and OPCODE_DIR2
to reflect actual locations of opcode files, so TAGS target will
be buildable.
i386-tdep.c: Change an erroneous 'm68k' reference to 'i386'.
i386-tdep.c (supply_fpregset, fill_fpregset): Remove m68k code.
m68k-tdep.c (supply_fpregset, fill_fpregset): Fix array
dereferencing to access the correct elements.
valops.c (value_addr): Declare return type of external func value_copy().
xcoffread.c: Undefine next_symbol_text before redefining it.
command that prints /proc specific information, changes to solib.c to
allow more flexible handling of finding the dynamic linker structures,
changes to utils.c and defs.h to add a new null_cleanup() function to
serve as an anchor point for cleanup chains with no obvious "first
cleanup".
Made some more progress in removing duplicate assembly opcode files.
More improvements to how mipsread and to a lesser extent dbxread work.
See the ChangeLog for details.
