    pub unsafe fn _mm_load_ps(p: *const f32) -> __m128

Available on (x86 or x86-64) and target feature `sse` and x86 only.
Expand description

Loads four `f32` values from aligned memory into a `__m128`. If the pointer is not aligned to a 128-bit boundary (16 bytes) a general protection fault will be triggered (fatal program crash).

Use `_mm_loadu_ps` for potentially unaligned memory.

This corresponds to instructions `VMOVAPS` / `MOVAPS`.
