The code size seems to be much worse than LLVM at least, unless I misread the graphs. Also my comment was in regard of the suggestion to try -Os -- -Os is not the answer for -O2 code size regressions. > Rather, we should seriously understand what caused the compilation time > jump in 4.2, and whether those are still a problem.

But, 4.2 was a disaster for compilation time. Yes that would be useful, although I admit for me personally make -j and icecream do a pretty good job at hiding that pain. -Andi -- a...@linux.intel.com -- Speaking for myself only.
