From 0c9da210f703f0cc98f7e198db1b68073091ce25 Mon Sep 17 00:00:00 2001 From: Craig Topper Date: Tue, 20 Mar 2012 05:28:39 +0000 Subject: [PATCH] When combining (vextract shuffle (load ), <1,u,u,u>), 0) -> (load ), add users of the final load to the worklist too. Needed by changes I'm preparing to make to X86 backend. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@153078 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/CodeGen/SelectionDAG/DAGCombiner.cpp | 1 + 1 file changed, 1 insertion(+) diff --git a/lib/CodeGen/SelectionDAG/DAGCombiner.cpp b/lib/CodeGen/SelectionDAG/DAGCombiner.cpp index 1bd1b95ad7d..7c4db97bfea 100644 --- a/lib/CodeGen/SelectionDAG/DAGCombiner.cpp +++ b/lib/CodeGen/SelectionDAG/DAGCombiner.cpp @@ -7353,6 +7353,7 @@ SDValue DAGCombiner::visitEXTRACT_VECTOR_ELT(SDNode *N) { // Since we're explcitly calling ReplaceAllUses, add the new node to the // worklist explicitly as well.
