* tree-ssa-threadedge.c (record_temporary_equivalence): Handle
NULL for RHS, which we used to invalidate equivalences.
(record_temporary_equivalences_from_phis): New bitmap arguments
and a boolean indicating if we have passed a backedge. If we
have passed a backedge, then set the appropriate bit in the
bitmaps for the SRC & DEST of PHIs creating equivalences.
(invalidate_equivalences, dummy_simplify): New functions.
(cond_arg_set_in_b): Remove.
(record_temporary_equivalences_from_stmts_at_dest): New bitmap
arguments and a boolean indicating if we have passed a backedge.
If we have passed a backedge, then perform invalidations as
needed.
(thread_around_empty_blocks): If we have seen a backedge, then
use the dummy simplify routine.
(thread_through_normal_block): Likewise. Pass bitmaps and
backedge status to children. Do not pessimize so much when
traversing backedges in the CFG.
(thread_across_edge): Manage the SRC_MAP/DST_MAP bitmaps.
If we have seen a backedge, then use the dummy simplify routine.
Do not pessimize so much when traversing backedges.
