[LLVMdev] data dependency and fully loop unrolling
...alysis that can 'undo' the
effects of loop unrolling, or do you want dependency analysis that can
run on the loop prior to unrolling?
For dependency analysis on loops (prior to unrolling) Preston and
Sanjoy have been working on this, see:

[LLVMdev] data dependency and fully loop unrolling
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,
