vec_orc

Purpose

Performs a bitwise OR-with-complement operation of the input vectors.

Note: This built-in function is valid when the -mcpu option is set to target POWER8 processors, or higher.

Syntax

d=vec_orc(a, b)

Result value

Each bit of the result is set to the result of the bitwise operation (a | ~b) of the corresponding bits of a and b. For 0 <= i < 128, bit i of the result is set to 1 only if the ith bit of a is 1 or the ith bit of b is 0.
