Hal Finkel 41418d17cc 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187926 91177308-0d34-0410-b5e6-96231b3b80d8		2013-08-07 22:49:12 +00:00
