           Summary: odd error for -O900
           Product: clang
           Version: trunk
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: Driver
        AssignedTo: unassignedclangbugs at nondot.org
        ReportedBy: gohman at apple.com
                CC: llvmbugs at cs.uiuc.edu


A user tried to extract an extreme amount of optimization from the compiler:

clang -O900 t.c
error: invalid value '4' in '-O900'

The value should either be silently accepted, or the message should be fixed.
