Function core::arch::x86_64::_m_pmovmskb

pub unsafe fn _m_pmovmskb(a: __m64) -> i32

🔬 This is a nightly-only experimental API. (stdsimd #48556)

This is supported on x86-64 and target feature sse,mmx only.

Takes the most significant bit from each 8-bit element in a 64-bit integer vector to create a 16-bit mask value. Zero-extends the value to 32-bit integer and writes it to the destination.
