| * | Make SCEVUnknown a CallbackVH, so that it can be notified directly | Dan Gohman | 2010-08-02 |
| | | | | | | | | | | | | | of Value deletions and RAUWs, instead of relying on ScalarEvolution's Scalars map being notified, as that's complicated at best, and insufficient in general. This means SCEVUnknown needs a non-trivial destructor, so introduce a mechanism to allow ScalarEvolution to locate all the SCEVUnknowns. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@110086 91177308-0d34-0410-b5e6-96231b3b80d8 | ||

| * | Factor out some of the code for updating old SCEVUnknown values, and | Dan Gohman | 2010-07-29 |
| extend it to handle the case where multiple RAUWs affect a single SCEVUnknown. Add a ScalarEvolution unittest to test for this situation. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@109705 91177308-0d34-0410-b5e6-96231b3b80d8 | |||
