[llvm-commits] [llvm] r108075 - /llvm/trunk/include/llvm/Target/TargetInstrInfo.h

New Revision: 108075

URL: http://llvm.org/viewvc/llvm-project?rev=108075&view=rev
Log:
Remove copyRegToReg from TargetInstrInfo so it is not longer accesible.

Use a COPY instruction instead for register copies, or TII::copyPhysReg() after
COPY instructions are lowered.

Targets should implement copyPhysReg instead of copyRegToReg.
