2001-03-30* thread-db.c (check_event): Don't report an error if we encounterMark Kettenis1-4/+5
a thread creation event for a thread that's already in the thread list, since that may legitemately happen. Instead only call attach_thread if it's not already in the thread list.
2001-03-01Create new file regcache.h. Update all uses.Andrew Cagney1-1/+2
2001-01-24* lin-lwp.c (lin_lwp_xfer_memory): Add attrib argument.J.T. Conklin1-1/+2
