[llvm-dev] How to pass StringRef or std::string type to external function

[SANGEETA CHOWDHARY via llvm-dev]

Hi,

I am trying to pass name of the file to external function but I am not able
to figure out how I can do it. Below is the code -

 auto *Scope = cast<DIScope>(Loc->getScope());
 StringRef fileName  = Scope->getFilename();
 errs()<<"fileName:"<<fileName<<"\n";


 Finish = M->getOrInsertFunction("finish", VoidTy);
 IRB.CreateCall(Finish, {});

How should I pass fileName to “finish” call?

Regards,
Sangeeta
