// Generated by decuda.
// Host-side runtime calls are translated to the `cust` crate. Kernels
// are emitted as `TODO(decuda)` blocks: rust-gpu translation requires
// the kernel to be authored as a Rust fn. See `examples/` for a
// scaffolded SPIR-V kernel module you can flesh out.
//
// Add to your Cargo.toml:
// [dependencies]
// cust = "0.3"
// Minimal fixture: no CUDA constructs at all. The parser must produce an
// empty IR and every backend must emit only its banner + the verbatim source.
