pub unsafe fn _mm_cmp_ss_mask<const IMM8: i32>(a: __m128, b: __m128) -> __mmask8

🔬 This is a nightly-only experimental API. (stdsimd #48556)

This is supported on x86-64 and target feature avx512f only.

Compare the lower single-precision (32-bit) floating-point element in a and b based on the comparison operand specified by imm8, and store the result in mask vector k.
