Summary: Dependence Analysis performs static checks to confirm validity of delinearization. These checks often fail for 64-bit targets due to type conversions and integer wrapping that prevent simplification of the SCEV expressions. These checks would also fail at compile-time if the lower bound of the loops are compile-time unknown.
