# [−][src]Function core::arch::x86::_mm_packs_pi32

    pub unsafe fn _mm_packs_pi32(a: __m64, b: __m64) -> __m64

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

Converts packed 32-bit integers from `a` and `b` to packed 16-bit integers using signed saturation.

Positive values greater than 0x7F are saturated to 0x7F. Negative values less than 0x80 are saturated to 0x80.
