WebFor 32-bit implementations, an n-bit right-rotation can be performed by a left-rotation of 32-n. The fixed-point shift instructions logically perform left and right shifts. The result of a shift instruction is placed in the target register under the control of a generated mask. Some POWER® family shift instructions involve the MQ register.
