Evan Cheng e57187cbe3 CreateVirtualRegisters does trivial copy coalescing. If a node def is used by a single CopyToReg, it reuses the virtual register assigned to the CopyToReg. This won't work for SDNode that is a clone or is itself cloned. Disable this optimization for those nodes or it can end up with non-SSA machine instructions. ... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@62356 91177308-0d34-0410-b5e6-96231b3b80d8		2009-01-16 20:57:18 +00:00
