Hi, all
I am trying to write a function pass to replace a old function to a new function like: int haha(int a) { } ==> int haha(int a, char *IO) { } The below is a part of my code and generate segmentation fault. Can you help me to fix it? Thanks, Shawn // Since we have now created the new function, splice the body of the old // function right into the new function, leaving the old rotting hulk of the // function empty. NF->getBasicBlockList().splice(NF->begin(), F.getBasicBlockList()); Value *Globals = NF->argend(); Globals->setName("globals");
You can't dereference arg_end... you might want to read up a bit on C++ iterators.
