autodiff

The tracking issue for this feature is: #124509.

This feature allows you to differentiate functions using automatic differentiation. Set the -Zautodiff=<options> compiler flag to adjust the behaviour of the autodiff feature. Multiple options can be separated with a comma. Valid options are:

PrintTA - print Type Analysis Information PrintAA - print Activity Analysis Information PrintPerf - print Performance Warnings from Enzyme Print - prints all intermediate transformations PrintModBefore - print the whole module, before running opts PrintModAfterOpts - print the whole module just before we pass it to Enzyme PrintModAfterEnzyme - print the module after Enzyme differentiated everything LooseTypes - Enzyme's loose type debug helper (can cause incorrect gradients) Inline - runs Enzyme specific Inlining NoModOptAfter - do not optimize the module after Enzyme is done EnableFncOpt - tell Enzyme to run LLVM Opts on each function it generated NoVecUnroll - do not unroll vectorized loops RuntimeActivity - allow specifying activity at runtime
