Description
I'm really glad the Rust CUDA project is being rebooted. Thanks for all the work going into it!
Not sure if this is known behaviour, but just in case here are the details.
Steps to reproduce:
- Clone rust-cuda main
- Add
.release(false)to theCudaBuilder::newcall in build.rs for one of the examples (I haven't tested path_tracer), e.g:
CudaBuilder::new(manifest_dir.join("kernels"))
.release(false)
.copy_to(out_path.join("kernels.ptx"))
.build()
.unwrap();
.release(false)
.copy_to(out_path.join("kernels.ptx"))
.build()
.unwrap();
- Observe the internal compiler error:
crates/rustc_codegen_nvvm/src/ty.rs:235:18: llvm_float_width called on a non-float type.
This was using the ubuntu24-cuda12 container.
