Function core::arch::x86::_mm_mask_fixupimm_ss

pub unsafe fn _mm_mask_fixupimm_ss<const IMM8: i32>(
    a: __m128, 
    k: __mmask8, 
    b: __m128, 
    c: __m128i
) -> __m128

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

This is supported on x86 and target feature avx512f 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.
