- compute size & offset at the same time. The side-effects of this are that we now support negative GEPs. It's now approaching a phase that it can be reused by other passes (e.g., lowering of the objectsize intrinsic) - use APInt throughout to handle wrap-arounds - add support for PHI instrumentation - add a cache (required for recursive PHIs anyway) - remove hoisting support for now, since it was wrong in a few cases sorry for the churn here.. tests will follow soon. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157775 91177308-0d34-0410-b5e6-96231b3b80d8
