But I thought it I have done some testing on the rc5 vs rc4 in the kernel compile test. ========rc5======= 1145.45user 514.38system 2:36.93elapsed 1057%CPU (0avgtext+0avgdata 235540maxresident)k 0inputs+12736outputs (0major+127283813minor)pagefaults 0swaps ================= ========rc4======= 1125.58user 523.66system 2:38.09elapsed 1043%CPU (0avgtext+0avgdata 235604maxresident)k 0inputs+12744outputs (0major+126738411minor)pagefaults 0swaps ================= I don't see the big different there. The second one shows a bit slower is likely due to I haven't warm up my machine to run the first round. It is likely that your test C file has a much bigger function than the average kernel function file. In for your case, even revert does not help you much right? Because you want the result IR has more correct SSA.
