Thanks for your last reply. Could I understand the way to adding a pass (built into the llvm rather than dynamic loadable) includes: 1. Declaring a creator function for this pass 2. Implementing the creator function for this pass 3. Instantiating this pass and get a object of it 3. Register this pass into the PassRegistry Then, for a built-into bytecode pass, task 1(declaration of the

...mon need, LLVM provides the Statistic<> template class that can be used to keep track of this kind of information. You can find various examples of statistic users, but this basics of using it are as follows: Define your statistic like this: static Statistic<> Foo("mypassname\t- The # of times I did stuff"); Whenever you make a transformation, bump the counter: ++Foo; That's all you have to do. To get 'opt' to print out the statistics gathered, use the '-stats' option: $ opt -stats -mypassname < program.bc > /dev/null...

Thank you very much for your suggestions. That's very helpful. However, since I'm trying to compile several somewhat large projects, I assume generating bitcode for each single file and linking them together might be painful (I don't want to modify too much the project makefiles). So I hope my pass can be used just with simple compilation command like "llvm-gcc
