GPU kernels in the [examples](examples) folder are written in SYCL C++ and compiled to SPIR-V for embedding into Go programs, which is a little bit hacky. You can also use `ocloc`, which is a common practice and you can search for the build doc elsewhere. The build pipeline uses `go generate` directives:

The `cmd/func2kernel` tool handles the LLVM IR transformation (`spir_func` → `spir_kernel`, address space 4 → 1) required by the SPIR-V backend.
