David, I got some more work on the Livermore Loops and I found out that the issue is the difference in the parameters between a single step and a multi step compilation. When you compile "clang kernel06.c" it works fine, but when you get all steps (clang -emit-llvm + llvm-as + opt + llc etc), the defaults options of each and how they interact is showing a bug in the code generated.
