> This is much more expensive than when I tested this the last time on August 2nd, 2021: https://llvm-compile-time-tracker.com/compare.php?from=380b8a603c6e8997819726b15a76b8f6c94aa21a&to=abb759c879725b7bc09a466e92c9b9eca7f8f483&stat=instructions:u At that time, the pass was pretty cheap, and as such a reasonable tradeoff. Now this doesn't seem to be the case anymore.

Taking the geomean of compile time change in the above table shows 0.23% increase in compile time. That is not acceptable?
