[LLVMdev] creating a vreg in eliminateFrameIndex()

[Steve King]

Hello LLVM,
The ARM target sometimes adds an instruction with a virtual register
in eliminateFrameIndex():

https://github.com/llvm-mirror/llvm/blob/master/lib/Target/ARM/ARMBaseRegisterInfo.cpp

This looks late for a virtual register to appear.  Where is this vreg made real?

Thanks,
