2002-07-11* Nodes now keep track of any global variables in themChris Lattner
* Only dead-node-eliminate nodes with no flags * Don't merge scalars, only merge what they point to. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2878 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2275 91177308-0d34-0410-b5e6-96231b3b80d8
2002-04-17Make data structure acurately get ALL edges, even loads of null fields ofChris Lattner
nodes that are not shadow nodes This fixes em3d to be _correct_ if not optimial git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2274 91177308-0d34-0410-b5e6-96231b3b80d8
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
2002-04-09Move FunctionArgument out of iOther.h into Argument.h and rename class toChris Lattner

2002-04-01Support resolving function arguments/return values to pointers that indexChris Lattner
into other objects. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2094 91177308-0d34-0410-b5e6-96231b3b80d8
2002-04-01Avoid incorrectly adding null values to the scalar map!Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2085 91177308-0d34-0410-b5e6-96231b3b80d8
2002-04-01Critical shadow nodes no do not know their parent explictly.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2084 91177308-0d34-0410-b5e6-96231b3b80d8
2002-04-01Minor cleanups (use dyn_cast instead of testing manually)Chris Lattner
Shadow nodes now don't explicitly know their parent. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2083 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
2002-04-01Increase limit for perimeterChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2081 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 the isEquivalentTo implementations here. They can probably be putChris Lattner
someplace nicer in the file though. * Add new dump method for debugging git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2064 91177308-0d34-0410-b5e6-96231b3b80d8
2002-03-31Print out the instruction instead of just the address!Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2063 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
2002-03-31* Convert CallMap to be a vector, because the keys can change, and the mapChris Lattner
doesn't resort! * Be more generous with the cached matches that we allow now. * Recursive calls should all work now! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2061 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* Add critical node supportChris Lattner

2002-03-27* Destroy alloca nodes when a graph gets inlinedChris Lattner
* Add links to all subtrees when a shadow node gets resolved * Add critical node handling git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2001 91177308-0d34-0410-b5e6-96231b3b80d8
2002-03-27* Optimizers return true on changeChris Lattner

2002-03-27* Because of optimization, the shadow nodes between arguments might getChris Lattner
removed. Check to see if they are there. * Repeat optimizations while changing git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@1997 91177308-0d34-0410-b5e6-96231b3b80d8
