bitmap.c (bitmap_elem_to_freelist): Set indx to -1.
2016-10-07 Richard Biener <rguenther@suse.de>
* bitmap.c (bitmap_elem_to_freelist): Set indx to -1.
* bitmap.h (bmp_iter_set): When advancing to the next element
check that we didn't remove the current one.
(bmp_iter_and): Likewise.
(bmp_iter_and_compl): Likewise.
* tree-ssa.c (release_defs_bitset): Do not remove worklist bit
we currently iterate on but keep a one-level queue.
* sched-deps.c (remove_from_deps): Do not clear current bit
but keep a one-level queue.
