From 171817ee8ae888d595734a1b911d77dfa235ec9e Mon Sep 17 00:00:00 2001 From: Hal Finkel Date: Wed, 7 Aug 2013 22:49:12 +0000 Subject: Add ISD::FROUND for libm round() All libm floating-point rounding functions, except for round(), had their own ISD nodes. Recent PowerPC cores have an instruction for round(), and so here I'm adding ISD::FROUND so that round() can be custom lowered as well. For the most part, this is straightforward. I've added an intrinsic and a matching ISD node just like those for nearbyint() and friends. The SelectionDAG pattern I've named frnd (because ISD::FP_ROUND has already claimed fround). This will be used by the PowerPC backend in a follow-up commit. llvm-svn: 187926 --- llvm/lib/CodeGen/SelectionDAG/SelectionDAGDumper.cpp | 1 + 1 file changed, 1 insertion(+) (limited to 'llvm/lib/CodeGen/SelectionDAG/SelectionDAGDumper.cpp') diff --git a/llvm/lib/CodeGen/SelectionDAG/SelectionDAGDumper.cpp b/llvm/lib/CodeGen/SelectionDAG/SelectionDAGDumper.cpp index d8ee221cb46..47bab32787b 100644 --- a/llvm/lib/CodeGen/SelectionDAG/SelectionDAGDumper.cpp +++ b/llvm/lib/CodeGen/SelectionDAG/SelectionDAGDumper.cpp @@ -142,6 +142,7 @@ std::string SDNode::getOperationName(const SelectionDAG *G) const { case ISD::FCEIL: return "fceil"; case ISD::FRINT: return "frint"; case ISD::FNEARBYINT: return "fnearbyint"; + case ISD::FROUND: return "fround"; case ISD::FEXP: return "fexp"; case ISD::FEXP2: return "fexp2"; case ISD::FLOG: return "flog"; -- cgit v1.2.3
