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.
