llvm dev - Mar 2017 - get function parameters (not arguments)

Hi Everyone,

Does anyone know to get function parameters? For example, I want to get e
and f in the call to function foo in the following code:

foo(inr a , int b){
    ....
}

main() {
    int e,f;
    e=10;
    f=22;
    *foo(e,f);*
}

I use the following code:

for (auto& A : (cast<CallInst>(BI))->arg_operands ()) errs()
<< A.dump();

but I get a and b instead.

Thank you and best

This sounds really weird. If you're analyzing a CallInst in main, %a
and %b shouldn't even be available. Can you show us your actual IR and
output?

Cheers.

Sorry i'm using the following code:

F = (cast<CallInst>(BI))->getCalledFunction();
for (auto& A : F->getArgumentList()) {
                    errs() << "------- " << A.getName()
<< " " << "11" <<
"\n";
           }

But how can I get the parameters (as e and f in the example)?

Thank you and best,
Mo
