From 706e7ab8710c8b4646a343472370dc6d79f30738 Mon Sep 17 00:00:00 2001 From: Chris Lattner Date: Sat, 1 Feb 2003 06:51:17 +0000 Subject: [PATCH] Fix a bug where we would incorrectly delete globals which had edges to alive nodes in a graph in the t-d pass. This slows down the TD pass by quite a bit (1/3), but is needed for correctness. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@5464 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Analysis/DataStructure/DataStructure.cpp | 3 --- 1 file changed, 3 deletions(-) diff --git a/lib/Analysis/DataStructure/DataStructure.cpp b/lib/Analysis/DataStructure/DataStructure.cpp index f1b6e420bb9..2c9a75c9a85 100644 --- a/lib/Analysis/DataStructure/DataStructure.cpp +++ b/lib/Analysis/DataStructure/DataStructure.cpp @@ -973,9 +973,6 @@ static bool CanReachAliveNodes(DSNode *N, hash_set &Alive, if (Visited.count(N)) return false; // Found a cycle Visited.insert(N); // No recursion, insert into Visited... - if (N->NodeType & DSNode::GlobalNode) - return false; // Global nodes will be marked on their own - for (unsigned i = 0, e = N->getSize(); i < e; i += DS::PointerSize) if (CanReachAliveNodes(N->getLink(i).getNode(), Alive, Visited)) { N->markReachableNodes(Alive); -- 2.34.1
