+
+ * 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.
+
Fri Apr 18 13:38:19 1997 Doug Evans <dje@canuck.cygnus.com>
