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

    pub unsafe fn _mm_cmp_sd(a: __m128d, b: __m128d, imm8: i32) -> __m128d

This is supported on x86-64 and target feature `avx,sse2` only.

Compares the lower double-precision (64-bit) floating-point element in `a` and `b` based on the comparison operand specified by `imm8`, store the result in the lower element of returned vector, and copies the upper element from `a` to the upper element of returned vector.
