--- Comment #1 from Alex Coplan <acoplan at gcc dot gnu.org> ---
Execution test for the testsuite:

#include <arm_mve.h>

__attribute((noinline,noipa))
unsigned foo(int8x16_t v, int8x16_t w)
{
    return vcmpeqq (v, w);
}

int main(void)
{
    if (foo (vdupq_n_s8(0), vdupq_n_s8(0)) != 0xffffU)
        __builtin_abort ();
}
