[LLVMdev] Getting the Stack Pointer
...hancing Fernando's register allocator
debugger and would like to add support for stack pointer semantics.
TargetRegisterInfo has a getFrameRegister method but that returns
(on x86) either ESP/RSP or EBP/RBP depending on whether frame
pointer elimination has been done.
Would it be ok to add a getStackPointerRegister method to TargetRegisterInfo?

Why do you need to do this in a register allocator? Typically you want to
refer to abstract frame indices. Wouldn't fernando's debugger use a
similar representation?

I don't need it in the allocator. I need it in Fernando...
