(AC_FUNC_SETPGRP): Add.
* aclocal.m4, configure, config.in: Regenerated.
* inflow.c (gdb_setpgid): Get rid of NEED_POSIX_SETPGID and
SETPGRP_ARGS. Always use setpgid if it is available, fall back on
setpgrp if it isn't. Use SETPGRP_VOID (defined by autoconf) to
distinguish between the two setpgrp flavours.

From 2000-03-17 Jakub Jelinek <jakub@redhat.com>:
* config/sparc/tm-sp64linux.h: New file.
Submitted by Paul Hilfinger (hilfingr@gnat.com)
and Andrei Petrov (and@genesyslab.com).
* findvar.c: Buffers of size MAX_REGISTER_RAW_SIZE or REGISTER_BYTES
must be allocated dynamically, since these are no longer constants.
* infcmd.c: Ditto.
* regcache.c: Ditto.
* remote.c: Ditto.
* sol-thread.c: Ditto.
* valops.c: Ditto.
* config/sparc/sun4sol2.mh (MH_CFLAGS): Add -I/usr/include/v9, as a
work-around for a missing Sun header file in solaris for sparc64.
* config/ns32k/tm-umax.h (FRAME_FIND_SAVED_REGS): Restore. It
appears to have been inadvertantly removed sometime in May 1999.
* Revert 2000-11-09 changes where shared library objects were
moved from NATDEPFILES to TDEPFILES on NetBSD targets. While
we'd like to be able to debug dynamically linked executables,
this makes it impossible to build a cross debugger on a many
hosts.
* config/i386/nbsd.mt: Remove solib.o, solib-svr4.o from TDEPFILES.
* config/i386/nbsdelf.mt: Likewise.
* config/m68k/nbsd.mt: Likewise.

* config/i386/nbsdelf.mh: Likewise.
* config/m68k/nbsd.mh: Likewise.
* config/ns32k/nbsd.mh: Likewise.
* config/powerpc/nbsd.mh: Likewise.
* config/sparc/nbsd.mh: Likewise.
Make Sparc a Multi-Arch target. Discard PARAMS macro (require ANSI).

supply_register. Provide 4-byte offset to compensate for diff
between size of the prgreg_t elements on a 64-bit host and size
of the registers for a 32-bit target. Fill all inaccessible regs
with zero so they won't keep being requested again and again.

definitions. Add enums for register names, to help debugging gdb.
This header file must work for non-multi-arch and for multi-arch.

AT_ENTRY_POINT definitions for CALL_DUMMY, for non-multi-arch case.
Define GDB_MULTI_ARCH.

config/frv/tm-frv.h (IEEE_FLOAT): For all ports that #define
IEEE_FLOAT, make sure they give it the value (1).
Change to rely on PIDGET etc.
* config/i386/nm-i386sol2.h (TARGET_HAS_WATCHPOINTS,
TARGET_CAN_USE_HARDWARE_WATCHPOINT, HAVE_CONTINUABLE_WATCHPOINT,

if they're larger than 32 bytes.
(REG_STRUCT_HAS_ADDR): Ditto.
* sparc-tdep.c (sparc_init_extra_frame_info): Use read_sp()

to hook. Otherwise send it to fputs.
* monitor.c monitor.h (monitor_get_dev_name): New function. Does
the obvious.

to _filtered forms to make output appear in GUIs. Replace all
uses of SERIAL_READCHAR with readchar, which has better error
checking.
* (e7000_parse_device): Add prototype.
* (readchar): Improve doc. Handle random serial errors.
* (expect): Disable notice_quit code. It's busted. Remove
serial error handling (it's now handled in readchar). Remove
remote_debug echoing. That's handled in readchar as well.
* (e7000_parse_device): Remove serial_flag arg. It's not
necessary.
* (e7000_open): Split into two pieces. Second part is
e7000_start_remote, and is error protected. Now, when we connect
to the target, we setup the initial frame and registers so that
the user gets an immediate indication of where the target is.
* (gch): Remove debug output. That's handled by readchar.
* (e7000_read_inferior_memory): Handle errors better.
* (_initialize_remote_e7000): Get rid of `<xxx>' things from

(they're not useful, you can't change, write or even read them)
* sparclet-rom.c: Remove includes of Unix system files.
Add function "sparclet_supply_register" so that parse_register_dump
will not seg-fault by calling a null function pointer.
Remove XMODEM support (unfinished work?).
Remove flag "MO_HANDLE_NL", so monitor's output can be read by humans.
Add fill command.
Remove colon from getreg.resp_delim so PSR register will work.
Remove pointer to sparclet_load (downloading SREC's doesn't work).
Null out local register names for %g0, all %cc and all %asr regs,
since the monitor can't report them. Will return zero instead.
* sparclet-stub.c: New -- remote protocol support for sparclet CPU.
* config/sparc/tm-sparclet.h: Re-arrange REGISTER_NAMES:
Add back %g0 and %psr, add %cc coprocessor regs, add %asr regs.
Adjust NUM_REGS and REGISTER_BYTES accordingly

disassembly.

select sparc/sparclite.
* config/sparc/{tm-sparc.h tm-sparclite.h}: Get rid of
TM_PRINT_INSN. Set TM_PRINT_INSN_MACH to
bfd_mach_sparc/bfd_mach_sparc_sparclite.
and MMALLOC_CHECK macros, and add comment indicating how host dependent
makefile fragment should modify MMALLOC_CFLAGS to not use mmalloc, or
to use it but to not do heap corruption checking.
* gdbserver/Makefile.in: Ditto.
* utils.c (init_malloc): Replace warning() use with direct call of
fprintf_unfiltered, since current_target has not yet been set and thus
we cannot use warning(). If we try to use mmcheck and it fails,
suggest that this configuration needs NO_MMCHECK or MMCHECK_FORCE
defined. Other small mmalloc related cleanups.

setmem command), MO_RUN_FIRST_TIME (if command to start process
running on target is different from one to continue execution),
MO_HEX_PREFIX (if addresses from monitor have a "0x" prefix).
* monitor.c,parse.c,sparc-tdep.c:
Don't require strings in the registers array. This is to allow
NULLs to be place holders in the tm-*.h file so that only minor
changes are needed when a new processor is introduced (eg, one
without floating point).
* sparc-tdep.c: Conditionally remove dependancies on floating point.
* sparclet-rom.c,config/sparc/sparclet.mt,config/sparc/tm-sparclet.h:

and pthread support, since pre-2.5 systems don't come with
libthread_db.so.1.
* procfs.c (info_proc): Use int instead of id_t. Old versions of
Irix don't see to define this.
returns a possibly modified pid.
* inftarg.c (ptrace_him): Now returns pid;
* m3-nat.c (m3_trace_him): Now returns pid;
* infcmd.c (run_command): Minor cleanup.
* infrun.c (wait_for_inferior): Add another check for one_stepped
near where we read the pc to avoid erroneously setting
random_signal for multi-threaded support.
* procfs.c: Add support for Solaris LWPs. Remove def of
LOSING_POLL. Many cleanups... Several workarounds for Solaris
lossage. System call entry and exit are now handled by
dynamically registered handlers.

number.
* (info_proc_syscalls): Ditto.
* sol-thread.c: New file. Implements Solaris thread support.

notify target-dependent code about new symbol tables.

target_pid_to_str.
* config/sparc/nm-nbsd.h (CHILD_PREPARE_TO_STORE): Move to here
from config/sparc/xm-nbsd.h.
* config/sparc/nm-sun4os4 (CHILD_PREPARE_TO_STORE): Ditto, from
config/sparc/xm-sparc.h.
* config/sparc/nm-sun4sol2.h: New file, renamed from nm-sysv4.h.
