can you replace cpuid.c in the main directory , and run config.guess for us
it should output model,family,etc dont try and configure mpir with this though thanks Jason penryn/core2 differences are very minor at the moment , just lshift,gmp-mparam On Thursday 16 April 2009 12:30:42 Jeff Gilchrist wrote: > On Thu, Apr 16, 2009 at 6:51 AM, Jason Moxham <ja...@njkfrudils.plus.com> wrote: > > Could you run config.guess from gmp-4.3.0 > > It is reporting: > core2-unknown-linux-gnu > > So when I force config to use --build=core2-pc-linux-gnu I get much > better results (as expected): > > Intel Xeon E5405 @ 2.0GHz (Family 6, Model 23, Stepping 6) > Linux 64bit, gcc version 4.1.2 > 83338 bits (25088 digits) > Library Time1 Time2 > ---------- --------- --------- > GMP 4.3.0 2m34.857s 2m34.835s > MPIR 1.1.0 2m58.627s 2m58.706s (--build=core2) > MPIR 1.0.0 3m00.482s 3m00.461s (--build=core2) > MPIR 1.0.0 3m17.198s 3m17.288s (default) > GMP 4.2.4 5m38.156s 5m38.173s > MPIR 1.1.0 5m45.308s 5m45.236s (default) > > Would using penryn-unknown-linux-gnu as Jason suggested actually make > a difference in the code selection compared to core2? > > Jeff. > > --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "mpir-devel" group.
