Hi all i took a look into LLVM benchmarks from nightly tester and ran Shootout tests on my own. Below go just few outlines. 1. results on my AMD AthlonXP and Xeon used by LLVM team are different sometime. In particular, both Shootout and Shootout-C++ show great speed up with LLVM (in comparison to GCC) on ackerman test on my AthlonXP. But here:

Hello list. I'm trying to rebuild the 2.6.9.67.0.20.EL kernel, but it fails even without modifications. How did I try it? Created a (non-root) build environment (not a mock ) Installed the kernel.scr.rpm and did a rpmbuild -ba --target=`uname -m` kernel-2.6.spec 2> prep-err.log | tee prep-out.log The build failed at the end: Processing files: kernel-xenU-devel-2.6.9-67.0.20.EL Checking
