dwarf2out.c (gen_array_type_die): Output DW_TAG_subrange_type for VECTOR_TYPEs using TYPE_VECTOR_SUBPARTS.
2010-09-10 Richard Guenther <rguenther@suse.de>
* dwarf2out.c (gen_array_type_die): Output DW_TAG_subrange_type
for VECTOR_TYPEs using TYPE_VECTOR_SUBPARTS.
* dbxout.c (dbxout_type): Manually deal with VECTOR_TYPE
using TYPE_VECTOR_SUBPARTS, not TYPE_DEBUG_REPRESENTATION_TYPE.
