Expand description

Load a 32-bit element into the low bits of the vector and sets all other bits to zero.

This intrinsic is provided for completeness and is equivalent to u32x4(*m, 0, 0, 0) (which doesn’t require unsafe).

§Unsafety

This intrinsic is unsafe because it takes a raw pointer as an argument, and the pointer must be valid to load 4 bytes from. Note that there is no alignment requirement on this pointer since this intrinsic performs a 1-aligned load.
