* monitor.h (monitor_dump_reg_block): Remove ATTR_FORMAT. * cli/cli-script.c (define_command): Call query directly, instead of passing it a buffer. * ocd.c (ocd_error): Pass error a constant format string. * remote-mips.c (mips_error): Use fputs_filtered.

/* 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. */
