Function core::arch::x86_64::_mm_mask_permutex2var_ps

pub unsafe fn _mm_mask_permutex2var_ps(
    a: __m128,
    k: __mmask8,
    idx: __m128i,
    b: __m128

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

Available on (x86 or x86-64) and target feature avx512f,avx512vl and x86-64 only.

Shuffle single-precision (32-bit) floating-point elements in a and b across lanes using the corresponding selector and index in idx, and store the results in dst using writemask k (elements are copied from a when the corresponding mask bit is not set).
