Thank you for your thoughtful response and for sharing your approach to complex division optimization. We encountered similar performance issues while analyzing SPEC2017 workloads, particularly in the handling of complex arithmetic, and were motivated to propose a solution grounded in the current design conventions of LLVM Flang. While our implementation aligns closely with existing patterns in the Flang complex runtime, we’ve found that your formulation provides a more principled and generalizable abstraction. It is both elegant and insightful, and indeed offers a more flexible foundation for future extensions in this area. In our benchmarks, we observed that the performance gains achieved by your approach are comparable to those of our implementation. We have carefully studied your proposal and found it to be genuinely inspiring. Your contribution exemplifies the clarity and depth characteristic of the LLVM community — something we hold in high regard. We look forward to learning more from your work and to further engaging with the community on this topic. Enjoy the rest of your day!
