pub unsafe fn _mm_cmpneq_ss(a: __m128, b: __m128) -> __m128

This is supported on x86 and target feature sse only.

Compares the lowest f32 of both inputs for inequality. The lowest 32 bits of the result will be 0xffffffff if a.extract(0) is not equal to b.extract(0), or 0 otherwise. The upper 96 bits of the result are the upper 96 bits of a.
