cfgloop.c (mark_loop_for_removal): Record former header when ENABLE_CHECKING.
2014-09-05 Richard Biener <rguenther@suse.de>
* cfgloop.c (mark_loop_for_removal): Record former header
when ENABLE_CHECKING.
* cfgloop.h (strut loop): Add former_header member when
ENABLE_CHECKING.
* loop-init.c (fix_loop_structure): Sanity check loops
marked for removal if they re-appeared.
