I've tried to go middle way this time and have `MultiSourceLocation` just as typedef. I modeled it after `MultiExprArg` which is `using MultiExprArg = MutableArrayRef<Expr *>;` But that approach can have different reasons and isn't necessarily applicable in this case. My problem here is that on one hand I think `MultiSourceLocation` might be a useful abstraction and in that case probably `Sema::BuildInstanceMessage` should use this type for its parameter. On the other hand I am struggling to come up with good explanation what `MultiSourceLocation` is. And that's an indication it's not a good abstraction. What do you think? ================ Comment at: clang/lib/Sema/SemaDeclAttr.cpp:6934-6938 +// Returns a number of method parameters if parsing is successful. +// In case of unsuccessful parsing SlotNames can contain invalid data. +static Optional<unsigned> +parseObjCMethodName(StringRef Name, SmallVectorImpl<StringRef> &SlotNames, + const LangOptions &LangOpts) { ---------------- erik.pilkington wrote: > Maybe tryParseReplacementObjCMethodName or something would be better? > parseObjCMethodName() is pretty vague.

But not sure about "Replacement". This function doesn't care how its output will be used so I don't think it is worth mentioning. I've updated comment for `Name` but not entirely satisfied with the wording. Will try to come up with something better and suggestions are welcome. https://reviews.llvm.org/D44589 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
