2003-07-16Rematerialize nodes from the globals graph into the current graphVikram S. Adve
after all callees are inlined into the current graph. NOTE: There's also a major bug fix for the BU pass in DataStructure.cpp, which ensures that resolvable indirect calls are not moved out to the globals graph, so that they are eventually inlined (if possible). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7189 91177308-0d34-0410-b5e6-96231b3b80d8
2003-07-16(1) Rematerialize nodes from the globals graph into the current graphVikram S. Adve
after all callers are inlined into the current graph. (2) Optimize the way a graph is inlined into its callees in the TD phase: (a) Use DSGraph::cloneReachableSubgraph to clone only a subgraph at each call site, for faster inlining. (b) Clone separately for the same callee at different call sites, since only the reachable subgraph is being cloned, not the entire caller graph. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7188 91177308-0d34-0410-b5e6-96231b3b80d8
2003-07-16Implement 2 important changes: (1) rematerialization from the globals graph,Vikram S. Adve
and (2) faster inlining by cloning only reachable nodes. In particular: (1) Added DSGraph::cloneReachableSubgraph and DSGraph::cloneReachableNodes to clone the subgraph reachable from a set of root nodes, into the current graph, merging the global nodes into thos in the current graph. The TD pass now uses this for faster inlining, and so does the next function. (2) Added DSGraph::updateFromGlobalGraph() to rematerialize nodes from the globals graph into the current graph in both BU and TD passes. (3) `I' flags are removed from all nodes in the globals graph, because they are difficult to maintain correctly and are not needed anyway. (4) Aux. function calls are only removed to the globals graph if they will never be resovled. (This is what fixed gap.) The immediate reason is that if we took these out of a function (and moved them to the globals graph) we would need to rematerialize these nodes into the function graph for every function in the BU pass. The longer term problem is that we would need to find a way to remove them from the globals graph iff they have been resolved on all paths through the call graph. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7187 91177308-0d34-0410-b5e6-96231b3b80d8
