tree-sra.c (create_access_replacement): Only rename the replacement if we can rewrite it into SSA form.
2012-03-12 Richard Guenther <rguenther@suse.de>
* tree-sra.c (create_access_replacement): Only rename the
replacement if we can rewrite it into SSA form. Properly
mark register typed replacements that we cannot rewrite
with TREE_ADDRESSABLE.
* tree-cfg.c (verify_expr): Fix BIT_FIELD_REF verification
for aggregate or BLKmode results.
