pub unsafe fn v128_load32_splat(m: *const u32) -> v128
Available on target_family="wasm" and target feature simd128 and WebAssembly only.
Expand description

Load a single element and splat to all lanes of a v128 vector.

While this intrinsic is provided for completeness it can also be replaced with u32x4_splat(*m) and it should generate equivalent code (and also not 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.
