Lots of fun, not enought time to write diarry this week. Still I am fixing important bugs in the SSE/MMX/x86-64 support for gcc 3.1, but had some time for mainline development too. I finally have the new datastructure for dominators, so I believe everything is in the place for mainline merigng of the new loop optimizer, but I am not quite sure whether we can do it, as I am leaving in one week, but lets have fun.
