old-cross-binutils/gdb/sparclet-rom.c
Stu Grossman 4ce7ba5188 * Makefile.in (SUBDIRS): Add mswin so that make cleanup cleans up
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.
