Expand description

Load a single-precision (32-bit) floating-point element from memory into the lower element of dst using writemask k (the element is copied from src when mask bit 0 is not set), and set the upper 3 packed elements of dst to zero. mem_addr must be aligned on a 16-byte boundary or a general-protection exception may be generated.
