Available on x86-64 only.
Expand description

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.
