gdfa: A Generic Data Flow Analyzer for GCC
The design and implementation of gdfa is motivated by the following objectives:
Instead of implementing specific analyses directly, it is useful to implement a generic driver that is based on a carefully chosen set of abstractions. The task of implementing a particular analyzer then reduces to merely specifying the analysis by instantiating these abstractions to concrete values.
A short guide to applying the patch, building GCC with gdfa, and testing gdfa can be found here.
