[LLVMdev] dependence analysis

[aparna kotha]

I am looking at analyzing llvm IR and discovering some data dependence
between values. I presently have code that looks like


i32 %5 = ..........
i32 %6 = sub i32 %5 , 1


Is there a method in llvm that I can query to find out that these differ by
1 always ? or do i need to write such a method myself for this
functionality.



Thanks a lot for your help
