Any solution to do alias analysis for intrinsic which contains offset

I am writing a backend for our DSP, and want to do alias analysis for the load/store intrinsic. But the intrinsic contains an offset, and also updates the base address, like:

MyStoreIntrin data, base, offset ; [base + offset] ← data, base ← base + offset

I investigated the alias analysis code and found it only analysis the BasePtr and the DataSize, but not the offset. Is there any solution for me do alias analysis for my intrinsic?
