SCLAMP
Signed clamp to minimum/maximum vector
Clamp each signed element in the destination vector to between the signed minimum value in the corresponding element of the first source vector and the signed maximum value in the corresponding element of the second source vector and destructively write the results in the corresponding elements of the destination vector. This instruction is unpredicated.
