Worked on the EnzymeAD/Enzyme-JAX repository to deliver a targeted correctness fix for the BroadcastIotaSimplify function, addressing an issue where the iota dimension was incorrectly mapped to the replicated axis instead of the data axis. Applied expertise in algorithm optimization and compiler design to ensure the function now uses the output dimension mapping, preventing broadcasting errors when handling 2D outputs. Expanded test coverage to include edge cases, reducing the risk of future regressions and improving code reliability. Collaborated on both the fix and the associated tests, with all changes clearly documented in the commit history. Utilized C++ and MLIR throughout.
