It sounds like alias analysis can help: https://llvm.org/docs/AliasAnalysis.html

Hi LLVM community,

I am trying to differentiate access to different array elements, for example: for (int i = 1; i < 10; i++) { a[i] = a[i] + 10; b[i] = a[i - 1] * 2; } If it is possible to tell it loads/stores 3 different array elements: a[i], b[i] and a[i - 1] at IR level?

Thanks for your time in advance! Best, Michael
