------- Comment #8 from dje at gcc dot gnu dot org 2010-05-20 14:25 ------- Has anyone tested if generating an instruction sequence that uses the carry bit actually improves performance on modern POWER processors? It reduces the number of instructions, which is good when optimizing for size, but that may not necessarily translate to performance.
