The default in the nvptx port for -misa=sm_xx is sm_30, but the ptxas of the latest cuda release (11.1) no longer supports sm_30.
Interestingly, at https://docs.nvidia.com/cuda/parallel-thread-execution/index.html#release-notes__ptx-release-history they still claim to support everything down to sm_10. (They talk about supported targets, but still.)
Fix this by setting -misa=sm_35 by default.
Can you update the release notes? The other question is whether and, if so, how we want to add support for newer PTX ISA versions than 3.1 = CUDA 5.0. In terms of PTX ISA itself, moving to 6.3 would be a great step forward but requires at least CUDA 10. Hence, it could either a bump of the minimal CUDA version or to have some way to specify the PTX version. Thoughty?
