Xoc is described in the paper
“Xoc, an extension-oriented compiler,”
ASPLOS 2008.
Austin Clements's master's thesis, “A Comparison of Designs
for Extensible and Extension-Oriented Compilers,” provides a more
detailed comparison of related work than the ASPLOS paper.
Xoc is implemented in a custom scripting language called zeta.
The ASPLOS paper describes and gives the rationale for zeta.
The xoc prototype is available for download.
This version of zeta differs in small ways from the software
described in the paper. The most obvious one is that the zeta
interpreter is now implemented in C++ instead of C.
It is known to build and run successfully on Ubuntu Linux 7.10.
