...BasicAA and TBAA being used to build MemorySSA. MemorySSA is essentially a cache itself, and we're building it with a stateless tool. We know that while building MemorySSA, there are no changes in the program, and yet, there is info that is computed again and again. One example is this patch: D57627 <https://reviews.llvm.org/D57627>. The patch adds a cache for PointerMayBeCaptured, which is cleared after every alias() call, in order to keep BasicAA stateless. In the example given in the patch, not clearing the isCapturedCache reduces compile times by another second. In some pathological...
