Autodifferentiation with FFT, with Enzyme?

As I mentioned just now in the Autodifferentiation with FFT and Enzyme? · Issue #597 · SciML/NonlinearSolve.jl · GitHub this actually works well in Julia 1.10, and I am happily using Enzyme with FFTW and it is efficient. Thanks again @danielwe The issues appears to be on Julia 1.11 (I tested this a few weeks back, so that might have changed). Having a general set of rules for Enzyme and FFTW somewhere would be nice though to make this a bit easier, and the above seems to work. For reference, I…

work fine on Julia 1.10. So far I cannot get them to work on 1.11 or 1.12. I also haven’t tested on GPU.
