I'll answer your and Jacks question together. > I don't think this is the best time to do that.

Note that Stage 3 isn't that strict as it may sound. Maintainers have quite amount of flexibility deciding what is considered a bug and thus a bugfix during Stage 3 (note that Stage3 is _not_ only for regression fixes). This includes obviously Graphite and LTO as well as target specific changes. What you won't see in Stage 3 is rewrites of infrastructure or adding of new optimization passes. Note that we have been in Stage 1 for about six month now which is IMHO enough (and unsurprisinlgy matches the length of Stage 1 of GCC 4.4). Richard.
