Worked on stabilizing the MooreToCore testing workflow within the llvm/circt repository, focusing on improving test reliability for compiler development tasks. Addressed a recurring issue by updating the test invocation path to use a file argument format, ensuring that circt-opt consistently receives the correct input file during MooreToCore conversion tests. This targeted bug fix aligned the test harness with the expected input pipeline, reducing intermittent failures in errors.mlir-based test runs. Leveraged skills in compiler development and testing, with a focus on MLIR, to enhance the robustness of the testing process and support more predictable and maintainable test outcomes.
