 ### Outputs
 
 - An `#[offload]` rustc-builtin-macro which makes a function definition known to the LLVM offloading backend.
+  - [x] Made a PR to enable LLVM's offloading runtime backend.
+  - [ ] Merge the offload macro frontend
+  - [ ] Merge the offload Middle-end
 
 - An `offload!([GPU1, GPU2, TPU1], foo(x, y,z));` macro (placeholder name) which will execute function `foo` on the specified devices.
 
 - An `#[autodiff]` rustc-builtin-macro which differentiates a given function.
+  - [x] Merge the Autodiff macro frontend
+  - [x] Merge the Autodiff Enzyme backend
+  - [ ] Merge the Autodiff Middle-end
 
 - A `#[batching]` rustc-builtin-macro which fuses N function calls into one call, enabling better vectorization.

 ### How about Safety?
 
-We want all these features to be safe by default, and are happy to not expose some features if the gain is too small for the safety risk. As an example, Enzyme can compute the derivative with respect to a global. That's probably too niche, and could be discouraged (and unsafe) for Rust.
