[LLVMdev] data dependency and fully loop unrolling

[Cheng Liu]

Hi, all

When I have a loop unrolled, in the loop body, the same element of the 
array may be accessed multiple times.
I see there are then load and store instructions and I can no longer 
trace the data dependency directly by comparing
the operands. So I am writing to see if anyone has done this or any 
methods in llvm that may help?

Best regards,
