[LLVMdev] Regarding llvm

I am trying to run a profiling pass for each Machine Basic Block so that I
can get execution count for them, but I am getting assertion error when I
run it through clang. I have used MachineProfileInfo and Profile estimator
as dependent passes over my pass. I am sending you the code for my pass.
the error says:
void llvm::PMTopLevelManager::schedulePass(llvm::Pass*): Assertion `PI &&
"Expected required passes to be initialized"' failed.

I am attaching the code. Can you help me out? also can you suggest better
ways for getting execution count of loops corresponding to each machine
basic block?

Thanks and Regards,
