llvm dev - May 2012 - [LLVMdev] No getSmallConstantTripCount function in current LLVM version

Hi, 

I cannot find the getSmallConstantTripCount function in the current LLVM. Can
anyone tell me whether there is still such a function to get the trip count in
LLVM?

Thank you very much.

Best,
Han

in LLVM?
 Hi Han Li,

     AU.addRequired<ScalarEvolution>();
     AU.addPreserved<ScalarEvolution>();

    ScalarEvolution *SE = &getAnalysis<ScalarEvolution>();
    SE->getSmallConstantTripCount(L, ExitingBlock);

If you only want to handle single exit loops then:
   ExitingBlock = L->getExitingBlock()
