_mm_maskz_rcp_sh in core::arch::x86 - Rust
Description: Compute the approximate reciprocal of the lower half-precision (16-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 7 packed elements from a to the upper elements of dst. The maximum relative error for this approximation is less than `1.5*2^-12`.
