INSTRUCTION SET REFERENCE
6.2.55
rotate
Mnemonic:
rotate
Format:
rotate
Description:
Copies src2 to dst and rotates the bits in the resulting dst operand to the left
(toward higher significance). Bits shifted off left end of word are inserted at
right end of word. The len operand specifies number of bits that the dst
operand is rotated.
This instruction can also be used to rotate bits to the right. The number of bits
the word is to be rotated right should be subtracted from 32 and the result
used as the len operand.
Action:
src2 is rotated by len mod 32. This value is stored in dst.
