[cfe-dev] Function Lookup in SemaExpr

[Aaron W.Hsu]

Dear Nikola:


Thanks for the introduction to LookupName() and LookupResult. I think this is exactly what I want, especially LookupSingleName(). However, I seem to require a DeclarationName, which I don’t have yet. I’m not sure how to get one. I just have a string which is the name of the function I wish to lookup (this is in C), and I don’t know how to get from there to a DeclarationName and the other information I need.

Create LookupResult and call LookupName on it passing appropriate DeclarationContext into which you're performing the lookup (can be a scope or record decl).

Dear Clang Developers:




Inside of SemaExpr.cpp when handling BinOps, I want to lookup the (Expr *) and (NamedDecl) of a function by its name. How can I do this?





Yours truly,
