Re: C -> C Compiler

The DMS Reengineering Toolkit
(http://www.semdesigns.com/Products/DMS/DMSToolkit.html) can be used
for this purpose. You can write many transforms directly in the
surface syntax of "C", that are applied to a parse tree; the result is
prettyprinted. For a very simple example, to fold nested if
statements together, you can write a rule (untested) as follows:


default base domain Cpp. // says we are working in the C++ domain


rule fold_nested_if(c1:condition,c2:condition,s:statement)
selection_statement -> selection_statement
        = "if (\c1) if{\c2) \s;" rewrites to "if (\c1 && \c2) \s;"
