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

Load packed double-precision (64-bit) floating-point elements from memory into dst using writemask k (elements are copied from src when the corresponding mask bit is not set). mem_addr must be aligned on a 16-byte boundary or a general-protection exception may be generated.
