Description

Implementation of fixed size array delinearization. Try to delinearize access function for a fixed size multi-dimensional array, by deriving subscripts from GEP instructions. Returns true upon success and false otherwise. \p Inst is the load/store instruction whose pointer operand is the one we want to delinearize. \p AccessFn is its corresponding SCEV expression w.r.t. the surrounding loop.
