	* linux-thread-db.c (thread_db_wait): Don't bother continuing if

	the wait result indicates the program terminated with a signal.

	* linux-nat.c (linux_nat_wait): For SIGILL and SIGTRAP, don't

	throw away the event if the user has specified nostop noprint.

gdb/testsuite:

	* gdb.arch/ia64-sigill.c: New test.
