  The size-change abstraction (SCA) is an important program abstraction for
termination analysis, which has been successfully implemented in many tools for
functional and logic programs. In this paper, we demonstrate that SCA is also a
highly effective abstract domain for the bound analysis of imperative programs.
  We have implemented a bound analysis tool based on SCA for imperative
programs. We abstract programs in a pathwise and context dependent manner,
which enables our tool to analyze real-world programs effectively. Our work
shows that SCA captures many of the essential ideas of previous termination and
bound analysis and goes beyond in a conceptually simpler framework.
