An "integrated compilation and performance monitoring infrastructure", facilitating compiler-optimization research and involves a collaborative effort by Hewlett Packard, University of Illinois and New York University.

Generalized compiler technology for custom parsing, analyzing, transforming, and prettyprinting computer languages, including C, C++, COBOL, Ada, Java, C#, SQL. Tasks range from metrics to migrations. [Commercial]

Rule-based structural transformation is utilized as a paradigm for rapid generation of complex programs.

The Wiki for the Tom programming language, developped at Loria by the Protheo team.

A Pattern matching transformation system.

CMI is an optimizing frontend for gcc which allows gcc to inline across module boundaries without requiring you to put inline functions in header files or even mark inline functions for inlining.

Providing a full range of information on program transformation, the site includes an online survey of the field and is updateable by visitors as featured by the concept of WikiWikiWeb.

A modular language for the specificat ion of fully automatic program transformation systems based on the paradigm of rewriting strategies. Free software.

CCured is a source-to-source translator for C. It analyzes the C program to determine the smallest number of run-time checks that must be inserted in the program to prevent all memory safety violations. The resulting program is memory safe, meaning that it will stop rather than overrun a buffer or scribble over memory that it shouldn't touch.

Multi-language software workshop for modeling, analyzing. Reads several languages, and outputs. Designed for object-oriented modeling (definition of classes and relations) and for migrating (to help convert) old code in older languages. Meets 2 needs: have a simplified software modeling workshop for small projects; make easier rewritings, ports, encapsulating non-OO code.
