Chris Lattner d5d0f9bd20 Eliminate the RegSDNode class, which 3 nodes (CopyFromReg/CopyToReg/ImplicitDef) ... used to tack a register number onto the node. Instead of doing this, make a new node, RegisterSDNode, which is a leaf containing a register number. These three operations just become normal DAG nodes now, instead of requiring special handling. Note that with this change, it is no longer correct to make illegal CopyFromReg/CopyToReg nodes. The legalizer will not touch them, and this is bad, so don't do it. :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22806 91177308-0d34-0410-b5e6-96231b3b80d8		2005-08-16 21:55:35 +00:00
