vec_sral: Vector Shift Right Arithmetic
d = vec_sral(a, b)Performs an algebraic right shift for a vector by a given number of bits. Each element of the
result is obtained by shifting the corresponding element of
a right by the number
of bits specified by the last 3 bits of every byte of b. The bits that are shifted
out are replaced by copies of the most significant bit of the element of
a.Note: For z14 or below, the low-order 3 bits of all byte
elements in
b must be the same, otherwise the result is undefined.| d | a | b | MIN ARCH |
