------- Comment #12 from sje at cup dot hp dot com 2010-03-22 20:48 ------- Since the proposed patch to meant to address non-optimimal code generation I decided to try the patch with SPEC2006 and see if it helped the performance. On SPECint, I got a 3% slowdown, mostly due to 429.mcf slowing down a lot (20%). 471.omnetap also slowed down (7%) and nothing else changed much. With SPECfp, we got a 0.36% speedup, with 434.zeusmp (4.4%) and 459.GemsFTDT (3.39%) speeding up the most and no significant slowdowns. I will try to see what happened with 429.mcf and see why that slowed down so much.
