Hello, Trying the 3.4.1 branch, I get following tests failing: LLVM :: CodeGen/X86/2009-06-05-VZextByteShort.ll LLVM :: CodeGen/X86/fma4-intrinsics-x86_64.ll LLVM :: CodeGen/X86/fp-fast.ll LLVM :: CodeGen/X86/vec_shift4.ll LLVM :: CodeGen/X86/vshift-4.ll I am testing on a Debian testing 64b. Does it ring a bell? Sylvestre
