Dan Gohman 4fbd796a12 Change ConstantSDNode and ConstantFPSDNode to use ConstantInt* and ... ConstantFP* instead of APInt and APFloat directly. This reduces the amount of time to create ConstantSDNode and ConstantFPSDNode nodes when ConstantInt* and ConstantFP* respectively are already available, as is the case in SelectionDAGBuild.cpp. Also, it reduces the amount of time to legalize constants into constant pools, and the amount of time to add ConstantFP operands to MachineInstrs, due to eliminating ConstantInt::get and ConstantFP::get calls. It increases the amount of work needed to create new constants in cases where the client doesn't already have a ConstantInt* or ConstantFP*, such as legalize expanding 64-bit integer constants to 32-bit constants. And it adds a layer of indirection for the accessor methods. But these appear to be outweight by the benefits in most cases. It will also make it easier to make ConstantSDNode and ConstantFPNode more consistent with ConstantInt and ConstantFP. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@56162 91177308-0d34-0410-b5e6-96231b3b80d8		2008-09-12 18:08:03 +00:00
