2002-12-06Fix several related bugs in DSNode::mergeWith() caused by theVikram S. Adve
fact that the incoming nodes may be merged away at intermediate steps. Use an extra level of indirection via DSNodeHandles to track the nodes being merged. All this now happens in a static helper function MergeNodes(). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@4947 91177308-0d34-0410-b5e6-96231b3b80d8

been missed if node *this got merged away due to recursive merging! Also, links were not moved correctly if a node is collapsed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@4933 91177308-0d34-0410-b5e6-96231b3b80d8
2002-11-27Fix logical error in TD pass: we should clear Mod/Ref bits of each callerVikram S. Adve

2002-11-12Fix two bugs:Chris Lattner
* The globals vector was getting broken and unsorted, this caused vortex to get badly pessimized * Node offset handling was being handled really poorly, and in particular we were not merging types with offsets right. This causes several graphs to be non-merged. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@4699 91177308-0d34-0410-b5e6-96231b3b80d8

2002-11-10* Dramatically rework liveness evaluation.Chris Lattner
* Implement the first step of the Globals graph: Deleting nodes from function graphs. In practice, these nodes need to be moved to the globals graph, but this will be taken care of later. Note that the graphs computed right now are not strictly correct! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@4681 91177308-0d34-0410-b5e6-96231b3b80d8
