Description: API documentation for the Rust `_mm_loadl_pi` fn in crate `core`.
Keywords: rust, rustlang, rust-lang, _mm_loadl_pi

# [−][src]Function core::arch::x86::_mm_loadl_pi

    pub unsafe fn _mm_loadl_pi(a: __m128, p: *const __m64) -> __m128

🔬 This is a nightly-only experimental API. (`stdsimd` #48556)
This is supported on x86 and target feature `sse` only.

Load two floats from `p` into the lower half of a `__m128`. The upper half is copied from the upper half of `a`.

This corresponds to the `MOVLPS` / `MOVLDP` / `VMOVLDP` instructions.

    #[cfg(target_arch = "x86")]
    use std::arch::x86::*;
    #[cfg(target_arch = "x86_64")]
    use std::arch::x86_64::*;

    let a = _mm_setr_ps(1.0, 2.0, 3.0, 4.0);
    let data: [f32; 4] = [5.0, 6.0, 7.0, 8.0];
    let r = _mm_loadh_pi(a, data[..].as_ptr() as *const _);
    // assert_eq!(r, _mm_setr_ps(5.0, 6.0, 3.0, 4.0));Run

## 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`)
