    Description

      During the code review for:

          8014326 [OSX] All libjvm symbols are exported
         JDK-8014326

      David Holmes request that I file an RFE for HotSpot to switch from
      mapfile based symbol exports to explicit visibility attributes and
      compiler flags.

      https://mail.openjdk.org/pipermail/hotspot-runtime-dev/2013-June/007803.html

      Of course, this will require investigation as to whether all of the
      compilers we support include support for explicit visibility attributes.
