[LLVMdev] rol/ror llvm instruction set
...l algorithms which are becoming ever more important rotation is a major operation. Thus including such instruction could reduce 3 instructions {shl, shr, or} into {rol | ror} which could gain considerable performance. However, the increased performance is not confined within crypto algorithms. -- Kasra
