Expand description

Bitwise OR-Combine, byte granule

Combines the bits within every byte through a reciprocal bitwise logical OR. This sets the bits of each byte in the result rd to all zeros if no bit within the respective byte of rs is set, or to all ones if any bit within the respective byte of rs is set.
