gcc : ChangeLog.tree-ssa tree-ssa-dom.c
Log message:
* tree-ssa-dom.c (optimize_stmt): Accept and pass down dominator
walker structure instead of individual varrays. Callers updated.
(eliminate_redundant_computations): Likewise.
(simplify_rhs_and_lookup_avail_expr): Likewise. Cache and update
a dummy COND_EXPR when querying the hash tables when transforming
DIV/MOD into RSHIFT/BIT_AND or ABS_EXPR into NEG_EXPR.
(dom_opt_walk_stmts): Don't reload the block data pointer each
iteration of the loop. Load it once outside the loop.
