[PATCH] D77962: PR38490: Support reading values out of __uuidof(X) expressions during constant evaluation.

[Arthur Eubanks via Phabricator via cfe-commits]

aeubanks added inline comments.


================
Comment at: clang/lib/AST/ExprConstant.cpp:3949
+      // Special-case reading from __uuidof expressions so we don't have to
+      // construct an APValue for the whole uuid.
+      if (LVal.Designator.isOnePastTheEnd()) {
----------------
