🔬 This is a nightly-only experimental API. (stdsimd #48556)
This is supported on x86-64 and target feature avx512f,avx512vl,avx only.
Expand description

Load contiguous active single-precision (64-bit) floating-point elements from unaligned memory at mem_addr (those with their respective bit set in mask k), and store the results in dst using writemask k (elements are copied from src when the corresponding mask bit is not set).
