GCC backend for Zilog Z8000 processor
This is a backend for GCC targeting the Zilog Z8000 microprocessor.
This code was written by Cygnus Solutions, and dates from approximately 1995-1998. It can still be downloaded from sourceware.org, packaged together with contemporaneous versions of GCC and other GNU tools.

A lightly modified version of the same backend can be found here, packaged together with the same ancient version (2.9) of GCC. This version of GCC will not compile with modern GNU tools.
