[John McCall via Phabricator via cfe-commits]

rjmccall added inline comments.


================
Comment at: lib/CodeGen/CGObjCMac.cpp:7457-7460
 CGObjCNonFragileABIMac::GetEHType(QualType T) {
   // There's a particular fixed type info for 'id'.
   if (T->isObjCIdType() || T->isObjCQualifiedIdType()) {
+    if (CGM.getTriple().isWindowsMSVCEnvironment())
----------------

> @rjmccall how should this be organized in the long run? At this point, the naming seems totally wrong. Is the non-fragile ABI sort of the canonical way forward for Obj-C, i.e. it's what a new platform would want to use to best stay in sync with the future of obj-c?
For Darwin, yes, absolutely.

I think this method should probably just completely delegate to the `CGCXXABI` using a new `getAddrOfObjCRTTIDescriptor` method.
