[-- Attachment #1: Type: text/plain, Size: 157 bytes --]

This adds two more builtin vector types:
vec64
vec64i (integer only)
It also sets the missing vector bit on the existing 128 bit types.

committed,
Andrew

* gdbtypes.c (build_builtin_type_vec128): Set the vector bit.
(build_builtin_type_vec128i): Set the vector bit.
* gdbtypes.h (builtin_type_vec64, builtin_type_vec64i): Declare.
* gdbtypes.c (builtin_type_vec64, builtin_type_vec64i): Define.
(build_builtin_type_vec64): New function.
(build_builtin_type_vec64i): New function.
(build_gdbtypes): Initialize builtin_type_vec64 and
builtin_type_vec64i.
