C to O-O Translation: Beyond the Easy Stuff
Can we reuse some of the huge code-base developed in C to take advantage of
modern programming language features such as type safety, object-orientation,
and contracts? This paper presents a source-to-source translation of C code
into Eiffel, a modern object-oriented programming language, and the supporting
tool C2Eif. The translation is completely automatic and supports the entire C
language (ANSI, as well as many GNU C Compiler extensions, through CIL) as used
in practice, including its usage of native system libraries and inlined
assembly code. Our experiments show that C2Eif can handle C applications and
libraries of significant size (such as vim and libgsl), as well as challenging
benchmarks such as the GCC torture tests. The produced Eiffel code is
functionally equivalent to the original C code, and takes advantage of some of
Eiffel's object-oriented features to produce safe and easy-to-debug

An Investigation Into the Generality of a Graphical Representation of Program Code for Source to Source Translation
This thesis addresses the problem of defining a source-to-source translation system for reusable software components. It describes the development of an interoperable language for writing software components, and presents a system to translate components written in the interoperable language to a set of compatible target languages. The common features in a set of popular programming languages are analyzed to inform the design of the interoperable language. An evaluation is performed by using the source-to-source translator to convert two well-known open source Java libraries to C++ and Python, and the accuracy and performance of the resulting translations are assessed
