Abstract
Many program optimisations and analyses, such as array-bound checking, termination analysis, etc, depend on knowing the size of a function's input and output. However, size information can be difficult to compute. Firstly, accurate size computation requires detecting
size relation
between different inputs of a function. Secondly, different optimisations and analyses may require slightly different size information, and thus slightly different computation. Literature in size computation has mainly concentrated on size checking, instead of inferencing. In this paper, we provide a generic framework on which different size variants can be expressed and computed. We also describe an effective algorithm for
inferring
, instead of checking, size information. Size information are expressed in terms of Presburger formulae, and our algorithm utilises the Omega Calculator to compute as exact a size information as possible, within the linear arithmetic capability.
