loop-init.c (loop_optimizer_init): Clear loop state when re-initializing preserved loops.
2013-02-13 Richard Biener <rguenther@suse.de>
* loop-init.c (loop_optimizer_init): Clear loop state when
re-initializing preserved loops.
* loop-unswitch.c (unswitch_single_loop): Return whether
we unswitched the loop. Do not verify loop state here.
(unswitch_loops): When we unswitched a loop discover new
loops.
