Function core::arch::x86_64::_mm_max_round_ss

pub unsafe fn _mm_max_round_ss(a: __m128, b: __m128, const SAE: i32) -> __m128

🔬 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 elements in a and b, store the maximum value in the lower element of dst, and copy the upper 3 packed elements from a to the upper elements of dst.
Exceptions can be suppressed by passing _MM_FROUND_NO_EXC in the sae parameter.
