One important thing this patch does, it splits isBaseOf with and without distance to avoid runtime selection. As for the caching, I believe it doesn't matter much, as on my test (lib/Sema/SemaOverload.cpp) most of the calls were asking one of a small number of table cells. Here's some data: * total calls: ~39M * total number of pairs asked: 1646 * 103 mostly asked cells cover 80% of all calls * 219 mostly asked cells cover 90% of all calls * 50 mostly asked rows (< 6kB) cover 97% of all calls if they're spread out you might still hit 50 different pages... The other solutions you've proposed are also interesting (especially #4 which is the most elegant, but requires some care in arranging the primes), but this one is the most straightforward, IMO. http://reviews.llvm.org/D5577
