Clang-11.0.0 Miscompiled SQLite
Question for any low-level optimizing compiler engineers here: I obviously realize these are all important, but in your judgment, how much of making an error-free compiler would you say is about having a comprehensive test suite, vs. having very careful software engineers, vs. having extremely thorough code reviews, vs. something else? Put another way, if you were to lose one of these, which ones do you think would have the most/least negative impact (or be the easiest/hardest to make up for with other things) in terms of the correctness of the final product?
