2006-12-05 Richard Guenther <rguenther@suse.de>
* config/i386/i386.c (ix86_builtin_vectorized_function): Declare.
(TARGET_VECTORIZE_BUILTIN_VECTORIZED_FUNCTION): Define.
(ix86_builtin_vectorized_function): New function to vectorize
sqrt.
* gcc.dg/vect/vect.exp: Add support for -fno-math-errno tests.
* gcc.dg/vect/vect-pow-2.c: Rename to ...
* gcc.dg/vect/no-math-errno-vect-pow-1.c: ... this. Require
vect_double, xfail for spu*-*-*.
