From 1e759999ca2ea2213dfd3d89daedc3d6ceb92f40 Mon Sep 17 00:00:00 2001 From: Chris Lattner Date: Tue, 1 Feb 2005 19:10:48 +0000 Subject: [PATCH] Signficantly speed up printing by not emitting the same file twice with different names. Large SCC's tend to be big, so this saves a lot of time. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@19970 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Analysis/DataStructure/Printer.cpp | 12 +++++++++--- 1 file changed, 9 insertions(+), 3 deletions(-) diff --git a/lib/Analysis/DataStructure/Printer.cpp b/lib/Analysis/DataStructure/Printer.cpp index eb7319df9ce..4d5fa81425e 100644 --- a/lib/Analysis/DataStructure/Printer.cpp +++ b/lib/Analysis/DataStructure/Printer.cpp @@ -274,9 +274,15 @@ static void printCollection(const Collection &C, std::ostream &O, Gr.getAuxFunctionCalls().size() : Gr.getFunctionCalls().size(); TotalCallNodes += NumCalls; - if (I->getName() == "main" || !OnlyPrintMain) - Gr.writeGraphToFile(O, Prefix+I->getName()); - else { + if (I->getName() == "main" || !OnlyPrintMain) { + Function *SCCFn = Gr.getReturnNodes().begin()->first; + if (&*I == SCCFn) + Gr.writeGraphToFile(O, Prefix+I->getName()); + else + O << "Didn't write '" << Prefix+I->getName() + << ".dot' - Graph already emitted to '" << Prefix+SCCFn->getName() + << "\n"; + } else { O << "Skipped Writing '" << Prefix+I->getName() << ".dot'...
