> Are you actually running a 2.6 kernel? Actually we are running it on 2.4 kernel. > Also, how did you run the tests? The tests are being run using DEJAGNU and the standard crosstool regression test framework. We also verified running individual tests using runtest. -Kunjan -----Original Message----- From: Daniel Kegel [mailto:dank@kegel.com] Sent: Thursday, June 17, 2004 12:26 PM To: Kunjan Naik Cc: 'crossgcc@sources.redhat.com' Subject: Re: floating point operations in gcc 3.3.3, glibc 2.3.2 Kunjan Naik wrote: > We were able to successfully build a toolchain using Dan's > crosstool-0.28-rc19 for x86 to ppc-750 and x86 to ppc405 architecture. > GCC 3.3.3, GLIBC 2.3.2 and 2.6 kernel headers were used to build the > toolchain.

Last time I ran a similar test (on the same hardware, probably) was gcc-3.3.1, and it did pretty well: http://www.kegel.com/crosstool/current/summaries/powerpc-750-linux-gnu-gcc-3 .3.1-glibc-2.3.2.gcc.sum That was running a 2.4 kernel, though. Are you actually running a 2.6 kernel? Also, how did you run the tests? - Dan ------ Want more information? See the CrossGCC FAQ, http://www.objsw.com/CrossGCC/ Want to unsubscribe?
