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
