Now that milestone2 is almost done, we get into the next round and we decided (basically during coffee break) to try something and change the compile flags for our i586 distribution (which is still the major one for openSUSE). If there aren’t major problems coming up with it, the next milestone will be compiled with -fomit-frame-pointer -mtune=generic instead of the old -march=i586 -mtune=i586.

It will feel around 20% faster, I’m sure 🙂

On unrelated news: I’m away for a very long Pentecost weekend. If there are issues with Factory, I won’t be able to fix them. See you in June!

  1. Doesn’t -fomit-frame-pointer break backtraces?

      Using dwarf debuginfo can follow the stackframes even without frame pointer.

      Ciao, Marcus

    So, when are we getting the Core2+ optimized desktop kernel with RT+PREEMPT? 🙂
