--- Comment #1 from Thomas Schwinge <tschwinge at gcc dot gnu.org> ---
Yeah.
This will need resolving via nvptx-tools 'as', see
<https://github.com/SourceryTools/nvptx-tools/issues/30> "[RFC] Handle sm_*
which is no longer supported by CUDA / ptxas exec check or configure check?".
As a work-around, you should be able to change 'target_arg = "sm_50";' near the
end in nvptx-tools 'nvptx-as.cc' to whatever the lowest 'sm_N' is that your
'ptxas' supports. (Or, build GCC/nvptx without CUDA/'ptxas' available, or
'configure' GCC/nvptx with a '--with-arch=[...]' that implies a 'sm_N' that
your 'ptxas' supports; see
'gcc/config/nvptx/nvptx.cc:first_ptx_version_supporting_sm'.)
