_mm_max_round_sh in core::arch::x86 - Rust
Description: Compare the lower half-precision (16-bit) floating-point elements in a and b, store the maximum value in the lower element of dst, and copy the upper 7 packed elements from a to the upper elements of dst. Exceptions can be suppressed by passing _MM_FROUND_NO_EXC in the sae parameter. Does not follow the IEEE Standard for Floating-Point Arithmetic (IEEE 754) maximum value when inputs are NaN or signed-zero values.
