[LLVMdev] Any solution to do alias analysis for intrinsic which contains offset

hi,
 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?

 Thanks,
 Yaorong
