[patch/in] Add some more vector types

[patch/in] Add some more vector types

[Andrew Cagney]

[-- 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.

How about some docs?

I don't think these specific builtin types need to be documented.

However, yes, we do need more generic documentation explaining how types 
and vectors hang together.
