record: signal a record goto stop to front-ends
The "record goto" command does not indicate the stop to front-ends. Instead, it prints the new location directly. Add a function to signal a normal stop to observers and have them print the new location. This function temporarily switches to the stopped thread. We use the TARGET_WAITKIND_NO_RESUMED wait status for this purpose. This should result in a stop notification without giving a stop reason. We could also invent a new wait status but this doesn't seem necessary at this point. Signed-off-by: Markus Metzger <markus.t.metzger@intel.com> gdb/ * record.h (record_signal_goto_stop): New. * record.c (record_signal_goto_stop): New.
