From ba3b1d10fd9bc3034a5947da7cc6e32a70ce23d4 Mon Sep 17 00:00:00 2001 From: Duncan Sands Date: Tue, 30 Oct 2007 12:40:58 +0000 Subject: [PATCH] If a call to getTruncStore is for a normal store, offload to getStore rather than trying to handle both cases at once (the assertions for example assume the store really is truncating). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@43498 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/CodeGen/SelectionDAG/SelectionDAG.cpp | 8 +++++--- 1 file changed, 5 insertions(+), 3 deletions(-) diff --git a/lib/CodeGen/SelectionDAG/SelectionDAG.cpp b/lib/CodeGen/SelectionDAG/SelectionDAG.cpp index 5b7f1b6e3b8..d92bb9cbd28 100644 --- a/lib/CodeGen/SelectionDAG/SelectionDAG.cpp +++ b/lib/CodeGen/SelectionDAG/SelectionDAG.cpp @@ -2460,7 +2460,9 @@ SDOperand SelectionDAG::getTruncStore(SDOperand Chain, SDOperand Val, int SVOffset, MVT::ValueType SVT, bool isVolatile, unsigned Alignment) { MVT::ValueType VT = Val.getValueType(); - bool isTrunc = VT != SVT; + + if (VT == SVT) + return getStore(Chain, Val, Ptr, SV, SVOffset, isVolatile, Alignment); assert(MVT::getSizeInBits(VT) > MVT::getSizeInBits(SVT) && "Not a truncation?"); @@ -2485,7 +2487,7 @@ SDOperand SelectionDAG::getTruncStore(SDOperand Chain, SDOperand Val, FoldingSetNodeID ID; AddNodeIDNode(ID, ISD::STORE, VTs, Ops, 4); ID.AddInteger(ISD::UNINDEXED); - ID.AddInteger(isTrunc); + ID.AddInteger(1); ID.AddInteger((unsigned int)SVT); ID.AddPointer(SV); ID.AddInteger(SVOffset); @@ -2494,7 +2496,7 @@ SDOperand SelectionDAG::getTruncStore(SDOperand Chain, SDOperand Val, void *IP = 0; if (SDNode *E = CSEMap.FindNodeOrInsertPos(ID, IP)) return SDOperand(E, 0); - SDNode *N = new StoreSDNode(Ops, VTs, ISD::UNINDEXED, isTrunc, + SDNode *N = new StoreSDNode(Ops, VTs, ISD::UNINDEXED, true, SVT, SV, SVOffset, Alignment, isVolatile); CSEMap.InsertNode(N, IP); AllNodes.push_back(N);
