[PATCH] D31630: [tsan] Detect races on modifying accesses in Swift code

[Dmitry Vyukov via Phabricator via llvm-commits]

dvyukov added a comment.

> We have 3 potential users for the external API (Go, Java, races on fd, potentially more in future).

Also add races on vptr to the list.



================
Comment at: lib/tsan/rtl/tsan_rtl.h:651
+  kExternalTagSwiftModifyingAccess = 1,
+  kExternalTagFirstUserAvailable = 128,
+  kExternalTagMax = 1024,
----------------
Why is it 128? It seems it should be 2.
