I am doing some finial stage testing and reviewing the const expr patch. I have find out that, my server actually do get affect by the CPU temperature. So I turn off the Intel Turbo Stepping. Allow some rest between test. Then I have finish write a script to do the testing per each commit. I include the log in the email. I can't narrow to one commit cause a big jump. No a reason to against the patch. I am just interested to see that the measurement can catch such change in numbers. Chris BTW, for testing purpose, I rebase against master. That is *not* how I am going to merge it. exp~0 17c0bae constexpr: flag __builtin_bswap() as constexpr real 1m24.786s user 20m18.346s sys 7m24.193s real 1m18.803s user 20m55.562s sys 7m36.994s real
