            Bug ID: 20391
           Summary: remarks should be controlled by -R flags, not -W flags
           Product: clang
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: release blocker
          Priority: P
         Component: -New Bugs
          Assignee: unassignedclangbugs at nondot.org
          Reporter: richard-llvm at metafoo.co.uk

    Classification: Unclassified

We should sort this out before 3.5 is released.

Per the original design, remarks should be governed by -R flags, not -W flags.
-Weverything should not affect remarks, and -Rerror= should not be possible.
Right now, we have an inconsistent state where diagnostics list [-Rblah] in the
message but the command line interface accepts -Wblah.
