            Bug ID: 65099
           Summary: nvptx offloading: hard-coded 64-bit assumptions
           Product: gcc
           Version: 5.0
            Status: UNCONFIRMED
          Keywords: openacc
          Severity: normal
          Priority: P3
         Component: libgomp
          Assignee: unassigned at gcc dot gnu.org

Primarily (only?) in libgomp, there are a few hard-coded 64-bit assumptions for
nvptx offloading, so 32-bit x86 (-m32) nvptx offloading doesn't currently work.

Also, the nvptx offloading compiler (that is, the compiler support libraries)
will then have to be built for both 32-bit and 64-bit multilibs.
