symbol_add_stub): Ditto.
* gdb/gdb_string.h (strdup): Declare only if not defined as a
macro.
Mark glibc development versions are defining strdup as a macro and the
prototype hosees it. Either way, this patch shouldn't cause problems.
* procfs.c: Added replacement macros for LWP stuff. Fixed support
for UnixWare / SVR4.2MP targets and any targets which use
multi-file /proc entries. Fixed support for hardware watchpoints.
* solib.c: SCO needs some of the same code as SunOS. Change

as new threads.
* procfs.c (wait_fd): Note if LWP has exited.
(procfs_wait): use GETPID to get process ID.
NOTE: I didn't commit Kean's changes to configure.host/configure.tgt
yet because they are kind of bogus and I'm punting back to him to let
him figure out what he's trying to do. So configuring for UnixWare
may not work just yet.

(sparc_push_arguments): New function.
(gdb_print_insn_sparc): New function.
(_initialize_sparc_tdep): Make gdb_print_insn_sparc the default
disassembler, so that SPARClite-specific instructions will
be recognized.
* sparcl-tdep.c (readchar): Print debugging information.
(debug_serial_write): New function, a replacement for SERIAL_WRITE
that prints debugging information.
* config/sparc/tm-sparc.h (PUSH_ARGUMENTS): Define.
(sparc_push_arguments): Declare.
* configure.tgt: Switch over to use tm-4320.h. Since I switched to
MIPS EABI the fixes are no longer backward compatible with 4300.
* tm-vr4320.h: Added
* vr4320.mt: Added
* utils.c: (warning) added call to warning_hook

of source vs. executable time stamp mismatch. Simplified object
file check. Initialized mtime to 0.

* top.c: added warning_hook prototype.
* gdbtk.c: (perror_with_name_wrapper) new function to call
perror_with_name safely.

Add prototypes.
* infrun.c (wait_for_inferior): Handle breakpoint hit in
signal handler without intervening stop in sigtramp.
* procfs.c (procfs_lwp_creation_handler): Use PROCFS_GET_CARRY
instead of direct access to the status register.
(procfs_get_pid_fd): New function, returns procfs fd for a given pid.
* sol-thread.c (ps_lgetLDT): New function, returns LDT for a given
lwpid.
(sol_find_new_threads): Handle failed libthread_db initialization
gracefully.
* stabsread.c (define_symbol): Use IS_STATIC_TRANSFORM_NAME
to check for a SunPro transformed symbol name.
* mips-tdep.c (unpack_mips16): Fixed instruction decoding, lots of
bit pattern interpretations. mips_fetch_instruction does not work
for 16 bit instructions. Some confusion remains about sign
extension in backward branches.
(mips32_relative_offset): Sign extension
(mips32_next_pc): Major debugging, bit pattern interpretation
(print_unpack): debugging printf
(fetch_mips_16): new funtion, key on PC low bit, not symbol table
(mips16_next_16): Initial major debugging of this function. Lots
of bit pattern mistakes.
(mips_next_pc): key on low bit of PC, not symbol table.
* symfile.c(generic_load) : Added a download verification which
reads back the loade code. Download chunk size is now a defined
macro. Fixed a bug in which downloading slips into loading one
byte at a time. Lower level functions in monitor.c can load long
sequences of bytes and make use of these fixups. Referencing
bfd-start_address directly was incorrectly getting zero for start.
section in an ELF file, override a symbol's ECOFF section with its
ELF section. Also, fix stabs continuation where a stabs string
continues for more than one continuation.
* ns32k-tdep.c (flip_bytes, ns32k_localcount,
ns32k_get_enter_addr, sign_extend): Restore functions mysteriously
deleted.

automake/autoconf.
* rdi-share/dbg_hif.h, etherdrv.c, hostchan.c: Use autoconf tests
to check environment.
automake/autoconfiscate rdi-share. We don't use the checks that autoconf
provides too much for now, but it'll be easier to use them if any problems
crop up in the future. (rdi-share/ is foreign code and it probably isn't
worth spending any more time than necessary messing with it.)

(gdbtk_init) added command "gdb_is_tracing".
(tracepoint_notify) added passcount information.
* tracepoint.c (trace_status_command): Recognize a boolean return
value from the stub to indicate whether trace experiment is
running. Export this value as a global state variable

* tracepoint.h export trace_running_p
* breakpoint.c (breakpoint_re_set_one): Treat bp_shlib_events
like bp_breakpoints.

if the alleged start address doesn't agree with the PC.
* gdbserver/Makefile.in: add dependency on XM_CLIBS.
* gdbserver/low-sim.c (registers) force into alignment.
(create_inferior): Fix typo on new_argv; add abfd arg to
sim_open, sim_create_inferior. Add reg_size arg to
sim_fetch_register, sim_store_register. Make simulator
take a single-step to get into a known running state.
* gdbserver/gdbreplay.c: include fcntl.h for def'n of F_SETFL.
* gdbserver/server.c: Add remote_debug variable to control
debug output.
* gdbserver/server.h: Add prototypes for enable/disable_async_io.
* gdbserver/remote-utils.c: add verbose debugging output controlled
by "remote_debug" variable. Add call to "disable_async_io()"
to avoid being killed by async SIGIO signals.
* config/m32r/m32r.mt: define GDBSERVER_(LIBS and DEPFILES),
so that gdbserver can be built with the m32r simulator.
unsigned types.
Specify size of r5900 FSR using 32 bit unsigned type.
Correctly format mips registers when some are not 64 bits in size
Check that REGISTER_{RAW,VIRTUAL}_SIZE are consistent when the target
specifies that no conversion is needed when moving from one to the
other.
* minsyms.c (compare_minimal_symbols): If addresses are identical,
then compare on names. Sorted list should have symbols with
identical addresses AND names adjacent, so dups can be discarded.
* config/m68k/xm-sun3os4.h: Remove malloc declarations, they
are handled via autoconf now.
* remote.c (remote_ops, extended_remote_ops): Replace static
forward declaration by moving the static definition to the top of
the file, for old K&R compilers.
* tracepoint.c (collect_symbol, trace_start_command):
Replace ANSI string concatenation with K&R compatible simple string.

* ser-unix.c (hardwire_drain_output): New function and prototype.
* ser-unix.c (hardwire_ops): Add entry for drain_output function.
* ser-tcp.c (tcp_ops): Ditto.
* ser-ocd.c (ocd_ops): Ditto.
* ser-mac.c (mac_ops): Ditto.
* ser-go32.c (dos_ops): Ditto.
* ser-e7kpc.c (e7000pc_ops): Ditto.
* serial.c (_initialize_serial): Add a description of
"set remotelogbase".
* command.c (do_setshow_command): If no arguments are supplied,
don't dump core, instead print out an error message.
* alpha-nat.c (fetch_osf_core_registers): Renamed from
fetch_aout_core_registers.
(alpha_osf_core_fns): Renamed from alpha_aout_core_fns, change
flavour to bfd_target_unknown_flavour for OSF core files.

a type which has TYPE_FLAG_TARGET_STUB set, if the target type has
set TYPE_FLAG_TARGET_STUB as well.
Patches from Peter.
so that targets can define their own register name aliases.
infcmd.c (registers_info): call target_map_name_to_register so that
"print $reg" and "info reg $reg" share the same register alias set.

is set properly.
(gdb_actions_command): Use free_actions () from tracepoint.c/h.
* m68k/tm-delta68.h (EXTRACT_RETURN_VALUE): Type argument for
`REGISTER_CONVERT_TO_VIRTUAL is `TYPE', not

D10V_CONVERT_DADDR_TO_RAW): Define.
* d10v-tdep.c (d10v_push_arguments): Re-write. Pass arguments in
registers, regardless of their size, when they fit.
o Fix code assuming that host/target were both bigendian.
o Replace d10v push dummy frame code with version using new common
generic generic version.
o Find/fix more cases where a value needs to be translated to/from
instruction (IMAP) or data (DMAP) spaces.
* tracepoint.c (tracepoint_operation): call free_actions instead
of free. (free_actions): eliminate some memory leaks for actions.
(validate_actionline): pass string arg by reference, so we can
change the pointer. Change all memrange collection arguments to
canonical form (literal address and size), to enforce early
evaluation. Accept UNOP_MEMVAL (assembly variables) for
trace collection. (parse_and_eval_memrange): accept expressions
for the address and size fields of a memrange (and evaluate
them immediately). (several places): use -1 instead of zero
