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

Add the lower single-precision (32-bit) floating-point element in a and b, store the result in the lower element of dst using zeromask k (the element is zeroed out when mask bit 0 is not set), and copy the upper 3 packed elements from a to the upper elements of dst.
