Errors I met when running this code.

I happen to be doing the same research，and found this awesome job.
This code runs very well, but I still met some errors about some test cases, for example, the 'susan' in Mibench.
Now I just make some null check, and dropped the error data, but I don't know if it will affect the analysis result.
The errors I met is as follows:

1. In file $Trident-master/llvm-2.9/lib/Transforms/CmpProfileValue/Hello.cpp,line 123 and 124:
   // // Convert float to double FPExtInst* convertInst1 = new FPExtInst(cmpInst->getOperand(0), Type::getDoubleTy(appModule->getContext()), "convt1", instPos); FPExtInst* convertInst2 = new FPExtInst(cmpInst->getOperand(1), Type::getDoubleTy(appModule->getContext()), "convt2", instPos);
   fails the assertion " assert(castIsValid(getOpcode(), S, Ty) && "Illegal FPExt");"at some time.

2. In file $Trident-master/llvm-2.9/lib/Transforms/StaticInstModeling/Hello.cpp, line 143:
   printf("%ld call %s: %.6f, %.6f, %.6f\n", curInstIndex, dyn_cast<CallInst>(curInst)->getCalledFunction()->getName(), curNode->accumPR, curNode->accumMR, curNode->accumCR);
   will report error some times.

Hi. Thanks for reporting the issue. Can you please provide us more details (i.e., IR code of your test case and steps to reproduce the bug etc) ?

Thanks very much for your quickly reply.
In this issue, I reported two errors I met.
The first one is about LLVMCPV.so.
The details is as follows, with the IR code file
basicmath_small_O0-llfi_index.zip

/home/xiaofengwo/Trident-master/llvm-2.9_my_build/bin/opt -S -load /home/xiaofengwo/Trident-master/llvm-2.9_my_build/lib/LLVMCPV.so -bishe_insert basicmath_small_O0-llfi_index.ll -o basicmath_small_profile_LLVMCPV.ll

The errors are:

opt: /home/xiaofengwo/Trident-master/llvm-2.9/lib/VMCore/Instructions.cpp:2555: llvm::FPExtInst::FPExtInst(llvm::Value*, const llvm::Type*, const llvm::Twine&, llvm::Instruction*): Assertion `castIsValid(getOpcode(), S, Ty) && "Illegal FPExt"' failed.

1. Running pass 'test function exist' on module 'basicmath_small_O0-llfi_index.ll'.

The second one is about SIM.so.
The details is as follows, with the IR code file
susan_code_mod_pass-llfi_index.zip
and 'select_stuples_file'
simplified_inst_tuples.zip

The errors are:
