I’m using Enzyme to perform automatic differentiation. I thought that as the primal code is type stable and non allocating, the enzyme autodiff function would also be. However for me the minimized example below gives the output: Autodiff time 0.000005 seconds (4 allocations: 192 bytes) It seems…

Also you can use Enzyme.API.printall!(true) to see the LLVM input code Enzyme sees as well as the derivative code generated. Simiarly Enzyme.API.printperf!(true) will print warnings of where there is a situation where it may need to cache (as it couldn’t prove or otherwise optimize it such that it c…

Ah! I think I’ve found what your mean: Base.Experimental.Const!
