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.
