WebSouffle employs a Datalog-like language as a domain specific language for static program analysis. Its finite domain semantics lends to efficient execution on parallel hardware using various levels of program specialisations. A specialization hierarchy is applied to a Datalog program. As a result, highly specialized and optimised C++ code is ...
