call it instead of doing normal loop. * infcmd.c (attach_command): Don't call wait_for_inferior if running Mach 3. * infrun.c (proceed) [PREPARE_TO_PROCEED]: If defined, call hook that can decide whether to step over the next breakpoint. * utils.c (wrap_here): Abort if wrap_buffer not allocated. (request_quit) [REQUEST_QUIT]: If defined, call it instead of doing normal quit. * Makefile.in (stop-gdb): New target. * stop-gdb.c: New file, utility to get attention of waiting GDBs in Mach 3.

A simple client to make GDB (versions 4.4 and later) on Mach 3 return
|
|
to the command level when it is waiting for the inferior to stop.
|
|
|
|
Actions: Lookup the send right to the GDB message port from the
|
|
NetMsgServer.
|
|
|
|
Send an asynchronous message with msgh_id
|
|
GDB_MESSAGE_ID_STOP to that port.
