search for: getcallee

Hi everyone: The code I am analyzing is : int main() { int i = 0; printf("hello world!"); printf( "%d" , i ); } I want to get each place where printf is called, and the argument used during that call. so I write llvm pass code like: void Myfunction( Function & F){ for( Function::iterator b = F.begin() , be = F.end() ;

There's a worked example at http://wiki.llvm.org/HowTo:_Find_all_call_sites_of_a_function . With the CallInst/InvokeInst you can query getArgOperand() to get the arguments or getCallee() which return a Function -- or it might not. If the call is an indirect call (ie., function pointer) then you don't know what it's calling. Ignoring indirect calls, you can call getName() on a function to get its name. Personally, I rely heavily on the doxygen to find my way around the...

Hi Eli, Thanks for the link! I'm able to compile a standalone pass outside of the source tree, and I'm obviously ably to compile analysis groups inside the source tree. However, the problem comes when I try to do what the tutorial suggests to create an analysis group outside of the source tree. My understanding is that building out of tree requires different methods to register the
