[PATCH] D77491: [Sema] Introduce BuiltinAttr, per-declaration builtin-ness

[John McCall via Phabricator via cfe-commits]

rjmccall added inline comments.


================
Comment at: clang/lib/Serialization/ASTWriter.cpp:3387
     Bits = (Bits << 1) | unsigned(II->isPoisoned());
-    Bits = (Bits << 1) | unsigned(II->hasRevertedBuiltin());
+    Bits <<= 1; // Previously used to indicate reverted builtin.
     Bits = (Bits << 1) | unsigned(II->hasRevertedTokenIDToIdentifier());
----------------
Clang bitcode isn't really a stable format, it's fine to just drop this bit.
