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->arg_end();
Globals->setName("globals");

========================================================== 150 Globals->setName("globals"); (gdb)
