...uction in a .bc file,which prints the opcode of every instruction before the instruction executed. While passing the opcode to the printf fucntion ,I used such way to convert the string to i8* (the same as http://lists.cs.uiuc.edu/pipermail/llvmdev/2012-September/053206.html does): StringRef s = ins_temp->getOpcodeName(); //ins_temp is an Instruction* type Constant *to_be_print = ConstantDataArray::getString(ctx, s); GlobalVariable *g_print = new GlobalVariable(M, to_be_print->getType(), true, GlobalValue::InternalLinkage, to_be_print, "print_str"); Constant *zero = Constant::getN...

Hi Jin, It's difficult to say just from looking at a pass, but one thing looked odd: > CallInst *call_print = CallInst::Create(call_print,paramArrayRef,"",ins_temp); This looks very dodgy. The "call_print" being used as an argument is the (uninitialised) one that's just been declared. This could be the source of the assertion failure (though a segfault is just as likely). Other than that I'd suggest hooking up a debugger and going up the c...
