 # UBSan blacklist.
-# Please think twice before you add or remove these rules.

-# This is a stripped down copy of Chromium's blacklist.txt, to enable
-# adding WebRTC-specific blacklist entries.

+# This is a WebRTC-specific replacement of Chromium's blacklist.txt.
+# Only exceptions for third party libraries go here. WebRTC's code should use
+# the RTC_NO_SANITIZE macro. Please think twice before adding new exceptions.
