tree-ssa-operands.c (get_expr_operands): Do not handle INDIRECT_REFs in the handled-component case.
2009-05-29 Richard Guenther <rguenther@suse.de>
* tree-ssa-operands.c (get_expr_operands): Do not handle
INDIRECT_REFs in the handled-component case. Remove
unused get_ref_base_and_extent case.
* tree-dfa.c (get_ref_base_and_extent): Avoid calling
tree_low_cst and host_integerp where possible.
* tree-ssa-structalias.c (equiv_class_label_eq): Check hash
codes for equivalence.
* dce.c (find_call_stack_args): Avoid redundant bitmap queries.
