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.
