There was a problem hiding this comment.
I'm not sure why I had builtin_macros_autodiff_unknown_activity not grouped together with the rest, but maybe combine them?

I've just grouped them so all autodiff-related errors are together.

@Sa4dUs It's not strictly necessary, but if you have some time, could you please remove the Remove test_ad commit and just update the previous commit to not include the binary blob? When possible it's preferable to have a cleaner history and let every commit build on it's own, since bors will just apply all of your commits unchanged (and not squash them). |

Done! Sorry for the oversight. |

Thanks! @bors r+ |

Prevent ICE in autodiff validation by emitting user-friendly errors This PR moves `valid_ret_activity` and `valid_input_activity` checks to the macro expansion phase in compiler/rustc_builtin_macros/src/autodiff.rs, replacing the following internal compiler error (ICE): ``` error: internal compiler error: compiler/rustc_codegen_ssa/src/codegen_attrs.rs:935:13: Invalid input activity Dual for Reverse mode ``` with a more user-friendly message. The issue specifically affected the test file `tests/ui/autodiff/autodiff_illegal.rs`, impacting the functions `f5` and `f6`. The ICE can be reproduced by following [Enzyme's Rustbook](https://enzymead.github.io/rustbook/installation.html) installation guide. Additionally, this PR adds tests for invalid return activity in `autodiff_illegal.rs`, which previously triggered an unnoticed ICE before these fixes. r? `@oli-obk`
