From d0ed240e3091607048490f174988976a44b11d30 Mon Sep 17 00:00:00 2001 From: Owen Anderson Date: Mon, 5 Jan 2009 18:32:26 +0000 Subject: [PATCH] Get rid of sentinel insertion in interval reconstruction. It just masked the problem, rather than fixing it. The problem has now been fixed the right way. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61723 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/CodeGen/PreAllocSplitting.cpp | 5 ----- 1 file changed, 5 deletions(-) diff --git a/lib/CodeGen/PreAllocSplitting.cpp b/lib/CodeGen/PreAllocSplitting.cpp index 576e9267f2e..d8e54e90f08 100644 --- a/lib/CodeGen/PreAllocSplitting.cpp +++ b/lib/CodeGen/PreAllocSplitting.cpp @@ -605,11 +605,6 @@ VNInfo* PreAllocSplitting::PerformPHIConstruction( else if (!intrablock && LiveOut.count(MBB)) return LiveOut[MBB]; - // Insert a sentinel into the map (which also acts as the DFS stack) so that - // we won't get stuck in infinite recursion when processing a loop. - if (!intrablock) - LiveOut[MBB] = 0; - typedef DenseMap > RegMap; // Check if our block contains any uses or defs. -- 2.34.1
