with a zero PC as frameless to improve backtraces from core dumps
caused by dereferencing a NULL function pointer.
(frameless_function_invocation, frame_saved_pc, rs6000_frame_chain):
Handle frameless functions interrupted by a signal.
* sparc-tdep.c (sparc_init_extra_frame_info, sparc_frame_saved_pc):

pi->prrun.pr_trace.
(unconditionally_kill_inferior): If PR_DEAD is defined,
rerun inferior after killing it.
floatformat_ieee_double_littlebyte_bigword for little endian
target byte order.
* utils.c (floatformat_to_doublest): Create local preswapped
copy of input for floatformat_littlebyte_bigword formats.
(get_field, put_field): Treat floatformat_littlebyte_bigword
the same as floatformat_little.

to CORE_ADDR.
* xcoffread.c (secnum_to_bfd_section): New routine to get
BFD section from CS section number.
(scan_xcoff_symtab): Make toc_offset section relative.

baseclass type is still undefined.
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.
o Provide poll_quit callback to simulators
so that they can poll for SIGINT on
clueless OS's.
o Add sim_stop to simulators so that clients
can request a halt (eg gdbtk's STOP button)
Works for PPC!
o Re-arange remote-sim.c so that the
hard work is moved from gdbsim_resume()
to gdbsim_wait() (where it should be).
