            Bug ID: 25322
           Summary: Allow explicitly suppressing
                    -fsanitize=unsigned-integer-overflow per expression
           Product: clang
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: Frontend
          Assignee: unassignedclangbugs at nondot.org

    Classification: Unclassified

-fsanitize=unsigned-integer-overflow has found _tons_ of bugs in my
applications.

There were, however, some false positive (where unsigned integer overflow is
explicitly used correctly). 

It would be nice to add a way to explicitly indicate this on a per expression
basis, so that the false positives can be removed from the reports of
-fsanitize=unsigned-integer-overflow.
