sbitmap.h (sbitmap_intersection_of_succs): Add prototype.
Wed Aug 25 13:55:47 EDT 1999 Andrew MacLeod <amacleod@cygnus.com>
* sbitmap.h (sbitmap_intersection_of_succs): Add prototype.
(sbitmap_intersection_of_preds, sbitmap_union_of_succs,
sbitmap_union_of_preds): Add prototypes.
* sbitmap.c (sbitmap_intersection_of_succs): New function to compute
the intersection of successors with the new flow graph structures.
(sbitmap_intersection_of_preds): New function to compute the
intersection of predecessors with the new flow graph structures.
(sbitmap_union_of_succs): New function to compute the union of
successors with the new flow graph structures.
(sbitmap_union_of_preds): New function to compute the union of
predecessors with the new flow graph structures.
* gcse.c (compute_rdm, compute_available): Use new sbitmap routines.
(expr_reaches_here_p): Use edge and basic_block structures instead
of s_preds and s_succs.
(compute_cprop_avinout): Use new sbitmap routines.
(pre_expr_reaches_here_p): Use edge and basic_block structures instead
of s_preds and s_succs.
* flow.c (compute_flow_dominators): Compute dominators using
edges and basic blocks instead of s_preds and s_succs.
