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.

Compiler architecture dynamically optimizes stand-alone programs via staged compiling. Uses run-time values and invariants to improve code as it executes, yielding performance superior to statically optimal code.

A Pattern matching transformation system.

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

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

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]

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 th...

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:...

Spoon is a Java program processor that fully supports Java 5. It provides a complete and fine-grained Java metamodel where any program element (classes, methods, fields, statements, expressions...) can be accessed both for reading and modification.

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.
