Tachyon Common Lisp: an efficient and portable implementation of CLtL2

Tachyon Common Lisp is an efficient and portable implementation of Common Lisp 2nd Edition. The design objective of Tachyon is to apply both advanced optimization technology developed for RISC processors and Lisp optimization techniques. The compiler generates very fast codes comparable to, and sometimes faster than the code generated by UNIX C compiler. Comparing with the most widely used commercial Common Lisp, Tachyon Common Lisp compiled code is 2 times faster and the interpreter is 6 times faster than the Lisp in Gabriel benchmark suit. Tachyon Common Lisp is the fastest among the Lisp systems known to the authors.
