I hope we judge optimizations based on whether they seem to improve (or not make worse) important benchmarks on important targets rather than the impossible standard of not making *any* code worse. (And cleanups likewise on not making a range of benchmarks worse.) A particular case made worse may still be a regression, but it could quite reasonably be a P4 or P5 regression depending on how much code is affected. -- Joseph S. Myers jos...@codesourcery.com
