[LLVMdev] dependence analyzer for machine code?

It is sparc independent and could be factored out. However, it operates on 
LLVM instructions (not machine instructions). There is no alias analysis 
or scalar evolution on machine instructions available (which is what my 
dependent analysis uses).

However, given a mapping of LLVM to machine instructions.. you can do it 
(as gross as that is). The stuff Chris is working on now is the better way 
of doing this.
