[PATCH] D50927: [Sema] Remove location from implicit capture init expr

[Vedant Kumar via Phabricator via cfe-commits]

vsk added inline comments.


================
Comment at: clang/lib/Sema/SemaLambda.cpp:1422-1424
   auto Entity = InitializedEntity::InitializeLambdaCapture(
       Var->getIdentifier(), Field->getType(), Loc);
   InitializationKind InitKind = InitializationKind::CreateDirect(Loc, Loc, Loc);
----------------

I've revised the patch to use one location consistently here. The tradeoff is that a few diagnostics now point to CaptureDefaultLoc instead of within the lambda body, but I'm happy to defer to more experienced Sema hands.


================
Comment at: clang/lib/Sema/SemaLambda.cpp:1612
+        auto InitResult = performLambdaVarCaptureInitialization(
+            *this, From, *CurField, IntroducerRange.getBegin(), IsImplicit);
         if (InitResult.isInvalid())
----------------

Sure. This does seem better for diagnostic reporting purposes. I'll just note that it may make the line table look awkward in the (admittedly unlikely) event that 'IntroducerRange.getBegin()' and 'CaptureDefaultLoc' are on different lines.
