--- Comment #4 from Tobias Burnus <burnus at gcc dot gnu.org> ---
Indeed, the following seems to also help with an older CUDA / JIT compiler.
Motivated by Thomas' work.

If we are sure that CUDA 11.0 fixes it, we could generate that code only fo=
r:

  if (version2[0] < 7 || sm_ver2[0] < 8)

given that sm_80 is only supported since CUDA 11.0 and, likewise, CUDA 11.0
introduces PTX ISA version 7.0.
