WebClightgen invokes the standard macro-preprocessor (to handle defineand include), parses, type-checks, and produces ASTs. Although your C programs may have side effects inside subexpressions, and memory dereferences inside subexpressions or if-tests, the program logic does not permit this. http://flint.cs.yale.edu/certikos/publications/device-journal.pdf
