            Bug ID: 77458
           Summary: nvptx offloading ICEs after "Implement C _FloatN,
                    _FloatNx types"
           Product: gcc
           Version: 7.0
            Status: UNCONFIRMED
          Keywords: openacc
          Severity: normal
          Priority: P3
         Component: lto
          Assignee: tschwinge at gcc dot gnu.org

  Target Milestone: ---

As of the PR32187 commit r239625 "Implement C _FloatN, _FloatNx types", nvptx
offloading is broken, ICEs in LTO stream-in.  Probably some kind of data-type
mismatch that is not visible with Intel MIC offloading (using the same data
types) but explodes with nvptx.  I'm having a look.
