such as a MIPS16 function, mark minimal symbol as special too.
* mips-tdep.c (pc_is_mips16): New function to check whether
a function is MIPS16 by looking at the minimal symbol. Use

instructions used by PMON and IDT monitor.
* config/mips/tm-embed.h: Enable hardware breakpoints on embedded
MIPS targets.
* config/mips/tm-mips.h: Define breakpoint instructions for
PMON and IDT monitor. Move MIPS16-related macros here from
mips-tdep.c.
* procfs.c: Substantial (but incomplete) changes to support
sysv4.2mp procfs as implemented in UnixWare 2.1. The procinfo
struct now has substructs like struct flt_ctl instead of
just a fltset_t and has a ctl_fd, status_fd, as_fd, and
map_fd instead of a single fd. Non-sysv4.2mp procfs models
still have the structs and multiple fds, but don't use the
entire struct and the four fds all point to the same thing.
We use PROCFS_USE_READ_WRITE to decide whether to talk to
procfs with reads/writes or use ioctl instead. We use
HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has
multiple fds or not. PROC_NAME_FMT is split out into
CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT,
STATUS_PROC_NAME_FMT.
(procfs_notice_signals): now a necessary wrapper around
(notice_signals): which are the new guts for noticing signals
(open_proc_file): gets a new flag arg used in sysv4.2mp to
determine whether or not to attempt to open the ctl_fd.
(procfs_read_status): new local function, reads procfs status
(procfs_write_pcwstop): new local function, writes a PCWSTOP
(procfs_write_pckill): new local function, writes a PCKILL
(unconditionally_kill_inferior): remove signo since we now
just call procfs_write_pckill().
(procfs_xfer_memory): call lseek with SEEK_SET rather than 0
(proc_iterate_over_mappings): the whole function is ifdefed
on UNIXWARE to keep things readable.
Expanded the syscall_table to include new potential sysv4.2mp
members. Note that all ifdefs of UNIXWARE should be eliminated
if possible or renamed to describe what's being selected for a
bit better. Sysv4.2mp and IRIX both have SYS_sproc so the
IRIX specific code now also checks it's not UNIXWARE.
* config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T,
HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE
* config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to
"/debug/%d" as PROC_NAME_FMT used to be
mips_skip_stub, mips_ignore_helper): New functions for dealing
with MIPS16 call/return thunks.

new code to skip over MIPS16 thunks.

to decide if certain library function calls should be ignored.
* config/mips/tm-mips.h (REGISTER_CONVERT_TO_TYPE,
REGISTER_CONVERT_FROM_TYPE): Swap words if target, not host,
is big-endian and if registers are 32 bits.
* mips-tdep.c (mips_print_register, mips_extract_return_value,
mips_store_return_value): Fix floating-point word-order problems on
little-endian targets introduced by changes of Mar 21.
* configure, configure.in: Allow gdbserver to be configured
for cross-target environments.
* gdbserver/Makefile.in: Add simulator support.
* gdbserver/configure.in: Eliminate assumption that host == target.
Simplify using gdb/configure.tgt and gdb/configure.host.
Fix other minor configuration errors.
* gdbserver/low-sparc.c: Fix compile error.
* gdbserver/remote-utils.c: Eliminate assumption that registers
and addresses are four bytes. Fix minor compile errors and warnings.

(mips_breakpoint_from_pc, mips_about_to_return): Declare.
* mem-break.c (memory_breakpoint_from_pc): New function.
(memory_insert_breakpoint, memory_remove_breakpoint): Use
memory_breakpoint_from_pc to determine breakpoint contents and size.
* target.h (memory_breakpoint_from_pc): Declare.
* monitor.c (monitor_insert_breakpoint): Use memory_breakpoint_from_pc
to determine size of breakpoint instruction.
* mips-tdep.c (mips32_decode_reg_save, mips16_decode_reg_save):
New helper functions for mips_find_saved_regs.
(mips_find_saved_regs): Recognize mips16 prologues.
(mips_addr_bits_remove): Strip off upper 32 bits of address
when target CPU is 32 bits but CORE_ADDR is 64 bits.
(mips_step_skips_delay): No branch delay slot on mips16.
(gdb_print_insn_mips): Disassemble mips16 code.
(mips_breakpoint_from_pc, mips_about_to_return): New functions.

instead of frame_saved_pc.
* config/m68k/tm-m68k.h: Define TARGET_M68K for Wingdb.
