I executed git pull --rebase origin main to see if build steps in autodiff job finish successfully after enzyme submodule update

No problem found

@bors try jobs=x86_64-gnu-autodiff

Rerunning to test potential cache effects.
Once this is done, we should ping Jakub and jieyouxu to discuss where to put it (and probably create an infra thread to discuss). I also don't think they'll accept autodiff as a culprit of measurably longer PR CI, so we'll probably need to move it, if the cache isn't helping enough.

Rebuilding a second time, since I'm not sure if artifacts are shared between PR Ci and try runs.
@bors try jobs=x86_64-gnu-autodiff

But so far, even just building LLVM+rustc+std+enzyme takes 95 minutes, 10 minutes more than miri, the next slowest job. Total time will always be a bit more than that, and autodiff will always have less users than something general like Miri, so that's hard to defend.

If the try results come back unchanged, can you move it to auto and mark it as allowed to fail? I don't think it needs to be blocking yet.

@ZuseZ4
CI succeeded. Can we land this? The job will remain optional for now.

ZuseZ4 commented Jul 23, 2026

I was just waiting for LLVM 23 to land, which hopefully is tomorrow. But since it's optional and you tested building under LLVM 23, I guess it doesn't really matter.
