# [−][src]Function core::arch::x86_64::_mm_sign_pi8

    pub unsafe fn _mm_sign_pi8(a: __m64, b: __m64) -> __m64

🔬 This is a nightly-only experimental API. (`stdsimd` #48556)
This is supported on x86-64 and target feature `ssse3,mmx` only.

Negates packed 8-bit integers in `a` when the corresponding signed 8-bit integer in `b` is negative, and returns the results. Element in result are zeroed out when the corresponding element in `b` is zero.
