ipa-reference.c (mark_load): Use get_base_address.
2010-04-07 Richard Guenther <rguenther@suse.de> * ipa-reference.c (mark_load): Use get_base_address. (mark_store): Likewise. * tree-ssa-ccp.c (gimplify_and_update_call_from_tree): Avoid inserting GIMPLE_NOPs into the IL. * tree-ssa-structalias.c (get_constraint_for_component_ref): Explicitly strip handled components and indirect references. * fold-const.c (fold_unary_loc): Do not strip qualifiers when folding address expressions. * gimple.c (gimple_ior_addresses_taken_1): Use get_base_address. * tree-ssa-alias.c (decl_refs_may_alias_p): Do not use operand_equal_p to compare decls. (ptr_deref_may_alias_decl_p): Likewise. * tree-ssa-operands.c (get_asm_expr_operands): Simplify * tree-ssa-forwprop.c (forward_propagate_into_gimple_cond): Handle reversed comparison ops. * tree-sra.c (asm_visit_addr): Use get_base_address. * ipa-prop.c (visit_store_addr_for_mod_analysis): Use get_base_address. * ipa-reference.c (mark_address): Use get_base_address.
