...oticed something about ADCE: it keeps an Alive set that requires a lot of upkeep time-wise, but if each instruction had a /single bit/ of side data (to represent liveness, solely within the pass), the set wouldn’t be needed. I tested this out and observed a ~1/3 reduction in time in ADCE: 1454ms to 982ms according to a profile over our test suite (for a total of 0.6% compile time savings in our pipeline). Are there any other passes that could benefit from having a single bit (or similarly small amount) of per-Instruction metadata local to the pass, i.e. to avoid having to keep a side-Set of instru...
