From 262d248833d8fa467970ad83f04ab1c523cb35b2 Mon Sep 17 00:00:00 2001 From: Mikhail Glushenkov Date: Wed, 12 Nov 2008 00:05:17 +0000 Subject: [PATCH] Add a bit of lazy evaluation to PopulateCompilationGraph(). Only the tools that are mentioned in the compilation graph definition are now inserted by PopulateCompilationGraph(). This should cut down plugin loading time a little. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59097 91177308-0d34-0410-b5e6-96231b3b80d8 --- utils/TableGen/LLVMCConfigurationEmitter.cpp | 29 ++++++++++++-------- 1 file changed, 18 insertions(+), 11 deletions(-) diff --git a/utils/TableGen/LLVMCConfigurationEmitter.cpp b/utils/TableGen/LLVMCConfigurationEmitter.cpp index 7836172a44c..33b0e3d8cb2 100644 --- a/utils/TableGen/LLVMCConfigurationEmitter.cpp +++ b/utils/TableGen/LLVMCConfigurationEmitter.cpp @@ -1595,26 +1595,33 @@ void EmitPopulateCompilationGraph (Record* CompilationGraph, { ListInit* edges = CompilationGraph->getValueAsListInit("edges"); - // Generate code O << "namespace {\n\n"; O << "void PopulateCompilationGraphLocal(CompilationGraph& G) {\n"; - // Insert vertices + // Insert vertices. + // Only tools mentioned in the graph definition are inserted. - RecordVector Tools = Records.getAllDerivedDefinitions("Tool"); - if (Tools.empty()) - throw std::string("No tool definitions found!"); + llvm::StringSet<> ToolsInGraph; - for (RecordVector::iterator B = Tools.begin(), E = Tools.end(); B != E; ++B) { - const std::string& Name = (*B)->getName(); - if (Name != "root") - O << Indent1 << "G.insertNode(new " - << Name << "());\n"; + for (unsigned i = 0; i < edges->size(); ++i) { + Record* Edge = edges->getElementAsRecord(i); + Record* A = Edge->getValueAsDef("a"); + Record* B = Edge->getValueAsDef("b"); + + if (A->getName() != "root") + ToolsInGraph.insert(A->getName()); + if (B->getName() != "root") + ToolsInGraph.insert(B->getName()); } + for (llvm::StringSet<>::iterator B = ToolsInGraph.begin(), + E = ToolsInGraph.end(); B != E; ++B) + O << Indent1 << "G.insertNode(new " << B->first() << "());\n"; + O << '\n'; - // Insert edges + // Insert edges. + for (unsigned i = 0; i < edges->size(); ++i) { Record* Edge = edges->getElementAsRecord(i); Record* A = Edge->getValueAsDef("a"); -- 2.34.1
