* Create Generic DOTGraphTraits Printer/ViewerTobias Grosser2010-01-161-0/+83
| | | | | | | | Move the DOTGraphTraits dotty printer/viewer templates, that were developed for the dominance tree into their own header file. This will allow reuse in future passes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@93632 91177308-0d34-0410-b5e6-96231b3b80d8

This patch also cleans up code that expects there to be a bitcast in the first argument and testcases that call llvm.dbg.declare. It also strips old llvm.dbg.declare intrinsics that did not pass metadata as the first argument. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@93531 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | Remove a FIXME and unify code that was necessary to work around broken updateDFSNumbers(). Before updateDFSNumbers() did not work correctly for post dominators. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@92968 91177308-0d34-0410-b5e6-96231b3b80d8
* Fix DFS number calculation for postdominatorsTobias Grosser2010-01-071-23/+29
| | | | | | | | | | The DFS number calculation for postdominators was broken. In the case of multiple exits that form the post dominator root nodes, do not iterate over all exits, but start from the virtual root node. Otherwise bbs, that are not post dominated by any exit but by the virtual root node, will never be assigned a DFS number. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@92967 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | | | | | | | phi translation of complex expressions like &A[i+1]. This has the following benefits: 1. The phi translation logic is all contained in its own class with a strong interface and verification that it is self consistent. 2. The logic is more correct than before. Previously, if intermediate expressions got PHI translated, we'd miss the update and scan for the wrong pointers in predecessor blocks. @phi_trans2 is a testcase for this. 3. We have a lot less code in memdep. We can handle phi translation across blocks of things like @phi_trans3, which is pretty insane :).
