This metabug is used to track all the patches which have been written during Stage 3 of GCC 4.2 but do not qualify for that stage, and are waiting for Stage 1 of GCC 4.3 to be applied. Please, do not attacch the patches to this bug. Open a new bug report, and mark it as "blocking" this metabug (this metabug will "depend" on the new bug report).
I know there are some C inlining changes and dwarf2/3 speeds up waiting for stage1.
4.3.0 stage 3 is now on so closing as fixed, the 4.4 meta bug is PR 33702.
