--- Comment #2 from Martin Liška <marxin at gcc dot gnu.org> ---
Even setting -mno-sse2 does not cause error. However this works as expected:

$ cat ~/Programming/testcases/pr80742.c && ./xgcc -B.
~/Programming/testcases/pr80742.c

typedef float __m128 __attribute__ ((vector_size (16)));

__attribute__((target("no-sse"))) __m128 func (__m128 x, __m128 y)
{
    __m128 xmm0 = x, xmm1 = y, xmm2;
    xmm0 = __builtin_ia32_xorps (xmm1, xmm1);
    return xmm0;
}
/home/marxin/Programming/testcases/pr80742.c: In function ‘func’:
/home/marxin/Programming/testcases/pr80742.c:5:1: error: SSE register return
with SSE disabled
 {
 ^

Negative meaning of option is definitely supported. That said, may I close the
PR?
