Function tracing::stdlib::arch::x86_64::_mm_maskz_rcp14_ss

pub unsafe fn _mm_maskz_rcp14_ss(k: u8, a: __m128, b: __m128) -> __m128

🔬This is a nightly-only experimental API. (stdarch_x86_avx512 #111137)

Available on x86-64 only.

Compute the approximate reciprocal of the lower single-precision (32-bit) floating-point element in b, store the result in the lower element of dst using zeromask k (the element is zeroed out when mask bit 0 is not set), and copy the upper 3 packed elements from a to the upper elements of dst. The maximum relative error for this approximation is less than 2^-14.
