[PATCH] D100567: BPF: emit debuginfo for Function of DeclRefExpr if requested

[Yonghong Song via Phabricator via cfe-commits]

yonghong-song added a comment.

To answer one of your questions above, if there is a function definition before, dyn_cast<llvm::Function>(...) will return nullptr. I tried starting from "Value" class and found dyn_cast to llvm::ConstantExpr will result in a non-null object, but I did not trace down further with subclasses of llvm::ConstantExpr.
