[LLVMdev] SimplifyCFG

[Andre Tavares]

Hello,

in the description of SimplifyCFG, it says that it can "Eliminates PHI 
nodes for basic blocks with a single predecessor."

I tested this pass with a program that has phi nodes with a single 
predecessor and it did not remove it. I also looked in the code and 
found nothing to remove it. I'm I missing something, or it does not 
remove phis with a single predecessor?

My sample is attached.
