Function _mm_mask_fixupimm_round_ss

pub unsafe fn _mm_mask_fixupimm_round_ss<const IMM8: i32, const SAE: i32>(
    a: __m128,
    k: u8,
    b: __m128,
    c: __m128i,
) -> __m128

🔬This is a nightly-only experimental API. (stdarch_x86_avx512)

Available on x86-64 only.

Fix up the lower single-precision (32-bit) floating-point elements in a and b using the lower 32-bit integer in c, store the result in the lower element of dst using writemask k (the element is copied from a when mask bit 0 is not set), and copy the upper 3 packed elements from a to the upper elements of dst. imm8 is used to set the required flags reporting.
Exceptions can be suppressed by passing _MM_FROUND_NO_EXC in the sae parameter.
