Support for CUDA 12.0 (libnvvm 2.0)

[n4o847]

Hello.

I just upgraded to CUDA 12.0 and I am getting the following error in cuda_builder:

error: rustc_codegen_nvvm requires at least libnvvm 1.6 (CUDA 11.2)

This seems to be because CUDA 12.0 uses libnvvm 2.0, which is incompatible with version 1 ^1, and the version check fails.

Is there any plan to support CUDA 12.0? Thanks in advance!

Environment

• Ubuntu 22.04
• Rust nightly-2021-12-04 (the same version as this repository)
• CUDA 12.0
• LLVM 7.1.0
