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
