There are a lot of cases that will trigger this assertion failure:
(`empty.cu` is a empty file)
- `-E`:
`../build/bin/clang-check empty.cu -- --offload-arch=sm_70 -E`
- multi-arch device-only
`../build/bin/clang-check empty.cu -- --cuda-device-only --offload-arch=sm_70 --offload-arch=sm_80`
- `-M`:
`../build/bin/clang-check empty.cu -- --offload-arch=sm_70 -M`
- `-fsyntax-only`:
`../build/bin/clang-check empty.cu -- --offload-arch=sm_70 -fsyntax-only`
Logs are basically the same:
