tree-ssa-alias.c (compute_flow_insensitive_aliasing): Make sure subvars get marked properly in tags for grouping.
2005-03-30 Daniel Berlin <dberlin@dberlin.org>
* tree-ssa-alias.c (compute_flow_insensitive_aliasing): Make sure
subvars get marked properly in tags for grouping.
(add_pointed_to_var): Mark only actual pointed to
variables/subvars in addresses needed.
(create_overlap_variables_for): Clear call clobbered on original
variable.
* tree-ssa-operands.c (get_asm_expr_operands): Don't let regular
addresable vars with subvars into list.
* tree-ssa.c (verify_ssa_name): Verify original is not used where
subvar should be.
