Requesting help for updating Rust-CUDA to newer rustc version. #95

Closed apriori closed 1 year ago

apriori commented 1 year ago

Hello everyone. It has been quite a while till the rust-toolchain has been updated. I've been trying to to get something up, but am kind of stuck due to lack of knowledge about the rustc codegen API. Can someone maybe take a look at my fork at https://github.com/apriori/Rust-CUDA/tree/update-to-latest-nightly and assist in its completion?

Definitely a great idea to get the toolchain updated!

The port compiles, however. Codegen does not seem to be working yet. Maybe someone of you can give it a try and also investigate. Make sure to get rid of register_attr in your gpu code as the feature has been dropped from rustc and is replaced with a scoped replacement register_tool that also requires a trampoline macro as shown in rust-gpu:c3a9b. My fork injects the no_std and register_tool via rustc flags incudabuilder, however, one still requires a use cuda_std::nvmm_internal.

I opened https://github.com/Rust-GPU/Rust-CUDA/pull/98. add_gpu is working in that state now. Further discussion should continue there.
