            Bug ID: 28415
           Summary: optimizer loop removal should issue diagnostics in
                    presence of "#pragma clang loop vectorize"
           Product: new-bugs
           Version: trunk
          Hardware: Macintosh
                OS: MacOS X
            Status: NEW
          Severity: normal
          Priority: P
         Component: new bugs
          Assignee: unassignedbugs at nondot.org

    Classification: Unclassified

If the optimizer decides to remove a loop that's tagged with "#pragma clang
loop vectorize(enable)", then some kind of diagnostic should be issued, instead
of silence as the case currently.

If/since the pragma is explicitly there, the programmer is obviously
expecting/requiring vectorization, so if that's not performed, she should be
warned.

This is related to PR28374.
