Re: Higher-level intermediate representation

The DMS Software Reengineeering Toolkit is designed to exactly this.


It parses C (and many other languages), automatically builds ASTs,
recording source file position, lexical shape information, comments,
and preprocessor directives. It can carry out source-to-source
transformations specified in the target language syntax (in this case, C),
as well as procedural source-to-source transforms. Finally,
it can prettyprint the resulting trees, reproducing the comments,
preprocessor directives, and lexical information that is unchanged
exactly. DMS also handles scale: it can process tens of thousands
of files in a single session, allowing you to perform transformations
that cross file boundaries.
