================
Comment at: llvm/trunk/test/Transforms/LICM/promote-tls.ll:67
+ %old = load i32, i32* %addr, align 4
+ ; deliberate impossible to analyze branch
+ %guard = load atomic i8*, i8** @p monotonic, align 8
----------------
Any particular reason why this can not be br i1 undef, label %a, label %b ? Understandably, this can be simplified by SimplifyCFG or SCCP. but we are only running LICM here ?
