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.

/* This structure describes the strings necessary to give small command
|
|
sequences to the monitor, and parse the response.
|
|
|
|
CMD is the actual command typed at the monitor. Usually this has
|
|
embedded sequences ala printf, which are substituted with the
|
|
arguments appropriate to that type of command. Ie: to examine a
|
|
register, we substitute the register name for the first arg. To
|
|
modify memory, we substitute the memory location and the new
|
|
contents for the first and second args, etc...
|
|
|
|
RESP_DELIM used to home in on the response string, and is used to
|
|
disambiguate the answer within the pile of text returned by the
|
|
monitor. This should be a unique string that immediately precedes
|
|
the answer. Ie: if your monitor prints out `PC: 00000001= ' in
|
|
response to asking for the PC, you should use `: ' as the
|
|
RESP_DELIM. RESP_DELIM may be NULL if the res- ponse is going to
|
|
be ignored, or has no particular leading text.
|
|
|
|
TERM is the string that the monitor outputs to indicate that it is
|
|
idle, and waiting for input. This is usually a prompt of some
|
|
sort. In the previous example, it would be `= '. It is important
|
|
that TERM really means that the monitor is idle, otherwise GDB may
|
|
try to type at it when it isn't ready for input. This is a problem
|
|
because many monitors cannot deal with type-ahead. TERM may be
|
|
NULL if the normal prompt is output.
|
|
|
|
TERM_CMD is used to quit out of the subcommand mode and get back to
|
|
the main prompt. TERM_CMD may be NULL if it isn't necessary. It
|
|
will also be ignored if TERM is NULL. */
