            Bug ID: 64780
           Summary: toplevel configure should reject jit as a language if
                    --enable-host-shared is not supplied
           Product: gcc
           Version: 5.0
            Status: UNCONFIRMED
          Keywords: build
          Severity: normal
          Priority: P3
         Component: jit
          Assignee: dmalcolm at gcc dot gnu.org
          Reporter: pinskia at gcc dot gnu.org

When I was going to test the JIT front-end but since I did not read the
documentation, I did not know I need to configure with --enable-host-shared.

I think it would be a good idea to either default to --enable-host-shared when
jit is a language or have the toplevel configure reject jit as language if
--enable-host-shared is not supplied.
