This is supported on x86-64 and target feature
avx512f
only.Expand description
Multiplies elements in packed 64-bit integer vectors a and b together, storing the lower 64 bits of the result in dst using writemask k (elements are copied from src when the corresponding mask bit is not set).
This intrinsic generates a sequence of instructions, which may perform worse than a native instruction. Consider the performance impact of this intrinsic.
