Can you give some sumary of changes you made? It would make it a lot easier to review if it was broken up int the generic changes (with rationaly why they are needed) and i386 backend changes that I could review then. >From first pass through the patch I don't quite see the need for i.e. adding new move patterns when we can output all kinds of SSE moves already. Will look more into the patch to see if I can come up with useful comments. Honza
