# Function core::arch::x86_64::_mm_loadr_ps 1.27.0[−][src]

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

This is supported on x86-64 and target feature `sse` only.

Load four `f32` values from aligned memory into a `__m128` in reverse order.

If the pointer is not aligned to a 128-bit boundary (16 bytes) a general protection fault will be triggered (fatal program crash).

Functionally equivalent to the following code sequence (assuming `p` satisfies the alignment restrictions):

    let a0 = *p;
    let a1 = *p.offset(1);
    let a2 = *p.offset(2);
    let a3 = *p.offset(3);
    __m128::new(a3, a2, a1, a0)

This corresponds to instructions `VMOVAPS` / `MOVAPS` followed by some shuffling.

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)

Search multiple things at once by splitting your query with comma (e.g. `str,u8` or `String,struct:Vec,test`)
