Function tracing::stdlib::arch::x86_64::_mm_mask_rsqrt_ph

pub unsafe fn _mm_mask_rsqrt_ph(src: __m128h, k: u8, a: __m128h) -> __m128h

🔬This is a nightly-only experimental API. (stdarch_x86_avx512_f16 #127213)

Available on x86-64 only.

Compute the approximate reciprocal square root of packed half-precision (16-bit) floating-point elements in a, and store the results in dst using writemask k (elements are copied from src when the corresponding mask bit is not set). The maximum relative error for this approximation is less than 1.5*2^-12.
