[PATCH] D155387: [Clang] Fix member lookup so that we don't ignore ambiguous lookups in some cases

[Shafik Yaghmour via Phabricator via cfe-commits]

shafik added inline comments.


================
Comment at: clang/lib/Sema/SemaOverload.cpp:15191
   OverloadCandidateSet::iterator Best;
   switch (CandidateSet.BestViableFunction(*this, OpLoc, Best)) {
   case OR_Success:
----------------
@rsmith if `R.isAmbiguous()` should we even check the overload candidates? 

Right now in `clang/test/SemaCXX/arrow-operator.cpp` we are getting both an 
ambiguous name lookup and overload diagnostic.
