Evan Cheng 17adafc6c1 Change the definition of TargetRegisterInfo::getCrossCopyRegClass to be more ... flexible. If it returns a register class that's different from the input, then that's the register class used for cross-register class copies. If it returns a register class that's the same as the input, then no cross- register class copies are needed (normal copies would do). If it returns null, then it's not at all possible to copy registers of the specified register class. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@127368 91177308-0d34-0410-b5e6-96231b3b80d8		2011-03-09 22:47:38 +00:00
