2002-07-10Reimplement data structure analysisChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2868 91177308-0d34-0410-b5e6-96231b3b80d8
2002-06-30Fix anand's last checkinChris Lattner

2002-06-25changes to make it compatible with 64bit gccAnand Shukla

2002-04-27Add support for tracking array allocationsChris Lattner

2002-04-16* Remove the concept of a critical shadow nodeChris Lattner
* Make the function pointer argument explicit for a call nodes * Eliminate unreachable global values * Merge call nodes that are identical git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2266 91177308-0d34-0410-b5e6-96231b3b80d8
2002-04-16* Eliminate ArgDSNode's completely, now rely on scalar mapChris Lattner
* Fold call nodes that are indistinguishable for each other. This is a big win for external functions like sqrt, which would multiply dramatically before. * Global nodes with no edges to or from them are now eliminated from the graph. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2257 91177308-0d34-0410-b5e6-96231b3b80d8
2002-04-01Allow merging of identical call nodes. Make the shadow node pointed toChris Lattner
by the call node noncritical before the call is destroyed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2082 91177308-0d34-0410-b5e6-96231b3b80d8
2002-03-31Unify the destruction code used for node pairs vs normal nodes. This wasChris Lattner
causing a problem before because global values with incoming edges didn't copy the incoming edges to the node they were being merged from, causing the poolalloc pass to die. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2079 91177308-0d34-0410-b5e6-96231b3b80d8
2002-03-31* Move isEquivalentTo implementations to NodeImplChris Lattner
* Implement a new form of node folding to catch cases missed in Addtree * Add removeIndistinguishableNodePairs to merge calls (todo) and globals git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2062 91177308-0d34-0410-b5e6-96231b3b80d8
2002-03-28Implement getEscapingAllocations & getNonEscapingAllocationsChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2021 91177308-0d34-0410-b5e6-96231b3b80d8
2002-03-28* Rename UnlinkUndistinguishableShadowNodes & RemoveUnreachableShadowNodesChris Lattner
to reflect that they can eliminate arbitrary nodes. * Rename the ShadowNodeEliminate.cpp file to EliminateNodes.cpp for the same reason git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2020 91177308-0d34-0410-b5e6-96231b3b80d8
2002-03-28Ooops, I did such a great job pruning nodes, that I accidentally deletedChris Lattner
ALL allocation nodes... hrm... bad. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2018 91177308-0d34-0410-b5e6-96231b3b80d8
2002-03-28Many changesChris Lattner
* Simplify a lot of the inlining stuff. There are still problems, but not many * Break up the Function representation to have a vector for every different node type so it is fast to find nodes of a particular flavor. * Do more intelligent merging of call values * Allow elimination of unreachable shadow and allocation nodes * Generalize indistinguishability testing to allow merging of identical calls. * Increase shadow node merging power git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2010 91177308-0d34-0410-b5e6-96231b3b80d8
2002-03-27* Add #define to enabled debug messagesChris Lattner
* Move removeEdgesTo to be a member of DSNode * Implement (but #ifdef out) the new, spiffier, method of determining shadow node equivalence. This cannot be enabled until more is implemented. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2004 91177308-0d34-0410-b5e6-96231b3b80d8
2002-03-27* Optimizers return true on changeChris Lattner
* Implement indistinguishable shadow node elimination git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@1999 91177308-0d34-0410-b5e6-96231b3b80d8
2002-03-26Initial checkin of Datastructure analysis.Chris Lattner
Has bugs, but shouldn't crash in theory. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@1994 91177308-0d34-0410-b5e6-96231b3b80d8
