rs6000.h (FUNCTION_VALUE): Only return vectors in an altivec register if TARGET_ALTIVEC.
2002-05-19 Aldy Hernandez <aldyh@redhat.com>
* config/rs6000/rs6000.h (FUNCTION_VALUE): Only return vectors in
an altivec register if TARGET_ALTIVEC.
* config/rs600/rs6000.c (rs6000_emit_move): Change VECTOR_MODE_P
to ALTIVEC_VECTOR_MODE.
(rs6000_va_arg): Only vectors of type AltiVec are 16 byte aligned.
(rs6000_va_arg): Vectors may go in registers if they are not
altivec vectors.
