[LLVMdev] scalar evolution to determine access functions in arays

[Jimborean Alexandra]

Ok, thank you, I will have a look and reply with questions if necessary. Does it take into consideration the existing phi nodes?

OK. In Polly we developed a pass called, 'independent-blocks-pass'. It basically creates basic blocks, that can easily be rescheduled without stopping the scalar evolution analysis to work. Maybe something similar can help you. Details about this pass are available in my thesis.
