By comparing CVS today with and without AREG4-AREG11 we can see that theI believe this need to be tested further. On the version I use (a CVS somewhat later that 0.6.0), and the regular gcc 3.3 on OSX 10.3.5 (TiBook G4/400), I get more or less a consistent 8% speed increase with -mcpu=7400 using Sandra on Win98 guest. Unless the flag interferes with AREG4-AREG11, it should get better./* XXX: suppress this hack */-change that Fabrice implemented gave us: Integer performance is +20%, Floating-point performance is -2%. --------------------------------------------------------------- Please take this with a grain of salt, I did only one test and cron might have kicked in during the tests... And yes, adding cpu-specific flags to gcc seems pointless.
Lga.
