ipa-devirt.c (odr_subtypes_equivalent_p): Compare TYPE_NAME only for aggregate types.
* ipa-devirt.c (odr_subtypes_equivalent_p): Compare TYPE_NAME only
for aggregate types.
(register_odr_type): Be ready for MAIN_VARIANT of ODR type
type to be non_ODR.
* tree.c (need_assembler_name_p): Compute mangled name for
non-fundamental types and integer types.
