--- Comment #13 from Richard Biener <rguenth at gcc dot gnu.org> --- Also look at gcc.opensuse.org/ in the c++bench "random" part. At -O2 it shows df live&initialized regs: 12.12 (31%) usr backwards jump threading: 6.44 (17%) usr the backwards jump threading thing is new. Jeff? At -O3 it runs OOM on vangelis, czerny reports 3.9GB memory use and besides the above: load CSE after reload : 120.58 (70%) usr I try to add most "interesting" compile-time/memory-use testcases to the C++ tester "random" part so we can track time-report / memory usage issues there. I think I've seen the load CSE after reload issue elsewhere, too.
