            Bug ID: 66264
           Summary: [untaken optimization] switch & enums without
                    default-case
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: jk3064 at arcor dot de
  Target Milestone: ---

example:
https://goo.gl/UFYF6G

Even when the switch() contains all enums, it won't use a lookuptable when no
default-case is given.

Should be switch-conversion doing the job?

Yes, I think so.  I'll try to have a look in the near future.
