From 0a29cb045444c13160e90fe7942a9d7c720185ed Mon Sep 17 00:00:00 2001 From: Tim Northover Date: Tue, 22 Jan 2013 09:46:31 +0000 Subject: Make APFloat constructor require explicit semantics. Previously we tried to infer it from the bit width size, with an added IsIEEE argument for the PPC/IEEE 128-bit case, which had a default value. This default value allowed bugs to creep in, where it was inappropriate. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@173138 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/CodeGen/SelectionDAG/LegalizeDAG.cpp | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'lib/CodeGen/SelectionDAG/LegalizeDAG.cpp') diff --git a/lib/CodeGen/SelectionDAG/LegalizeDAG.cpp b/lib/CodeGen/SelectionDAG/LegalizeDAG.cpp index db3abafcba..d37edab66e 100644 --- a/lib/CodeGen/SelectionDAG/LegalizeDAG.cpp +++ b/lib/CodeGen/SelectionDAG/LegalizeDAG.cpp @@ -2805,7 +2805,8 @@ void SelectionDAGLegalize::ExpandNode(SDNode *Node) { SDValue True, False; EVT VT = Node->getOperand(0).getValueType(); EVT NVT = Node->getValueType(0); - APFloat apf(APInt::getNullValue(VT.getSizeInBits())); + APFloat apf(DAG.EVTToAPFloatSemantics(VT), + APInt::getNullValue(VT.getSizeInBits())); APInt x = APInt::getSignBit(NVT.getSizeInBits()); (void)apf.convertFromAPInt(x, false, APFloat::rmNearestTiesToEven); Tmp1 = DAG.getConstantFP(apf, VT); -- cgit v1.2.3
