--- Comment #7 from Mark Wielaard <mark at gcc dot gnu.org> --- Author: mark Date: Wed May 21 15:44:59 2014 New Revision: 210717 URL: http://gcc.gnu.org/viewcvs?rev=210717&root=gcc&view=rev Log: PR debug/16063. Add DW_AT_type to DW_TAG_enumeration. Add a new lang-hook that provides the underlying base type of an ENUMERAL_TYPE. The default implementation will just use type_for_size. The implementation for C++ will use the ENUM_UNDERLYING_TYPE if it exists. Use this enum_underlying_base_type lang-hook in dwarf2out.c to add a DW_AT_type base type reference to a DW_TAG_enumeration. gcc/ * dwarf2out.c (gen_enumeration_type_die): Add DW_AT_type if DWARF version >= 3 or not strict DWARF. * langhooks.h (struct lang_hooks_for_types): Add enum_underlying_base_type. * langhooks.c (lhd_enum_underlying_base_type): New function. * gcc/langhooks.h (struct lang_hooks_for_types): Add enum_underlying_base_type. * langhooks-def.h (lhd_enum_underlying_base_type): New declaration. (LANG_HOOKS_ENUM_UNDERLYING_BASE_TYPE): New define. (LANG_HOOKS_FOR_TYPES_INITIALIZER): Add new lang hook. gcc/cp/ * cp-lang.c (cxx_enum_underlying_base_type): New function. (LANG_HOOKS_ENUM_UNDERLYING_BASE_TYPE): Define.
