Flow insensitivity and imprecision

Flow insensitivity and imprecision. If you ignore flow, then you lose precision. main() { x := &y; ... x := &z; }. Flow insensitive analysis tells us that x may point to z here!. But, insensitivity may alleviate two bottlenecks: (1) space : mem exhausted by large programs
