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.

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

specs
(wiggler_mourn): unpush_target with current_ops, not &wiggler_ops
(flash_xfer_memory): delete
(noop_store_registers): new placeholder replacement for
target_store_registers() which prevents generic_load from trying to
set up the PC.
(bdm_update_flash_command): add store_registers_tmp variable,
make handling of wiggler_ops more generic -- define wiggler_ops
in a target-specific file instead (such as ppc-bdm.c in the case
of the ppc), use current_target to deal with registers again
making this file less target-specific.
(bdm_read_register_command): new
(_initialize_remote_wiggler): stop doing add_target (&wiggler_ops),
comment out add_cmd ("read-register", ...)
* ocd.h: new, contains common wiggler prototypes, command definitions

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.
ChangeLog sh-tdep.c config/sh/tm-sh.h
* config/sh/tm-sh.h: add define for FPSCR_REGNUM
* sh-tdep.c (sh_show_regs): print out all registers for
the current processor
that directory.
* defs.h utils.c (error warning): Make message be const.
* main.c (fputs_unfiltered): Only send gdb_stdout and gdb_stderr
to hook. Otherwise send it to fputs.
* monitor.c monitor.h (monitor_get_dev_name): New function. Does
the obvious.
* remote-e7000.c: Remove debugify stuff. Change printf, fprintf
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
command names. They show up when doing completion and confuse
things horribly.
* ser-e7kpc.c: Remove the last seven months of brain damage. Get
rid of the DLL's since we can access the device directly from Win32s
and Win95. Get rid of debugify crud.
* serial.c: Remove debugify cruft.
* (serial_logchar serial_log_command serial_write serial_readchar
serial_send_break serial_close): Merge common functionality into
serial_logchar. Clean up rest of routines.
* sparclet-rom.c: Disembowel. Leave only download routine.
Download routine now switches to remote target automatically.
* top.c (disconnect): Only define if SIGHUP is defined. Cleans
up MSVC/Win32 problem.
* utils.c (gdb_flush): Don't call hook unless it's for gdb_stdout
or gdb_stderr.
* config/sh/tm-sh.h: Define TARGET_SH for WinGDB.
* config/sparc/tm-sparclet.h: Remove override for prompt.
* 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().

IRIX specific code now also checks it's not UNIXWARE.
