From e545d38a2871dd4fc93802d9405373325baf1e21 Mon Sep 17 00:00:00 2001 From: Eli Friedman Date: Sat, 16 Apr 2011 23:25:34 +0000 Subject: PR9055: extend the fix to PR4050 (r70179) to apply to zext and anyext. Returning a new node makes the code try to replace the old node, which in the included testcase is killed by CSE. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@129650 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/CodeGen/SelectionDAG/DAGCombiner.cpp | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'lib/CodeGen/SelectionDAG/DAGCombiner.cpp') diff --git a/lib/CodeGen/SelectionDAG/DAGCombiner.cpp b/lib/CodeGen/SelectionDAG/DAGCombiner.cpp index 378c13b..f427511 100644 --- a/lib/CodeGen/SelectionDAG/DAGCombiner.cpp +++ b/lib/CodeGen/SelectionDAG/DAGCombiner.cpp @@ -3884,7 +3884,7 @@ SDValue DAGCombiner::visitZERO_EXTEND(SDNode *N) { // CombineTo deleted the truncate, if needed, but not what's under it.
