* sysdeps/x86/fpu/test-math-vector-sincos.h (INIT_VEC_PTRS_LOOP):
|
|
Use a union when storing pointers.
|
|
(VECTOR_WRAPPER_fFF_2): Do not take address of integer vector and
|
|
cast result when passing to INIT_VEC_PTRS_LOOP.
|
|
(VECTOR_WRAPPER_fFF_3): Likewise.
|
|
(VECTOR_WRAPPER_fFF_4): Likewise.
