* breakpoint.c (breakpoint_re_set): #ifdef GET_LONGJMP_TARGET
around calls to create_longjmp_breakpoint. Why install the
breakpoints if we can't find the longjmp target?
* infrun.c (wait_for_inferior): Cleanup comments near call test.
* remote-mips.c: Fixed a bunch of prototypes to avoid char/int
complaint from picky compilers. Add comment to mips_expect.
Replace all instances of sr_get_debug with remote_debug.
* (mips_readchar): Don't jam init string to monitor.
mips_initialize() handles that.
* (mips_receive_header): Print better message when we get too
much garbage.
* (mips_request): Allow caller to pass in buff to allow them to
analyze the returned message.
* (mips_initialize): Re-do initialization to try sending a BREAK,
a ^C, and then a download escape sequence. Cleanup protocol
startup. Eliminate sleeps. Clear breakpoints (if using monitor
breakpoints). Re-init frame.
* (mips_detach): Close down target.
start-sanitize-gm
* (mips_resume): Pass signal down to target.
* (mips_create_inferior): Start target with TARGET_SIGNAL_PWR.
end-sanitize-gm
* (mips_wait): Handle return status with registers, or breakpoint stuff.
* (mips_kill): Add ^C handling.
* (mips_insert_breakpoint mips_remove_breakpoint): Call new
breakpoint stuff if enabled.
* (calculate_mask remote_mips_set_watchpoint
remote_mips_remove_watchpoint remote_mips_stopped_by_watchpoint):
Hardware watchpoint/breakpoint stuff.
* (common_breakpoint): Common code for new monitor breakpoint commands.
* (mips_load): Don't use `prompt'. It's a global variable.
* top.c (dont_repeat_command): New command for use in
user-defined commands to suppress auto-repeat (by hittin return key).
start-sanitize-gm
* utils.c (request_quit): Call target_kill here. Good idea.
Needs a better implementation.
end-sanitize-gm
* valops.c: Add start of auto function-call abandonment capability.
start-sanitize-gm
* c-exp.y: Add code (currently disabled) to handle GM dynamic
structures (it conflicts with @!).
* eval.c (evaluate_subexp_standard): ditto.
* expprint.c (print_subexp dump_expression): ditto.
* expression.h (enum exp_opcode): ditto.
* parse.c (length_of_subexp): ditto.
* configure, configure.in: Add mip*-*-magic* target.
* magic.c magic.h: Special routines to handle GM stuff (like
stepping through dispatcher).
