LLVM's use of a very rich (and hence not as memory efficient) IR is deeply rooted. Phases assume that given any value, you can trace your way to its uses, users, and owners. The LLVM code I've played with assumes this all over the place, so removing the use lists and owner links as B3 does would be super hard. B3 can do it because we started off that way. |
