Update 28 June 2015: XXICC has been updated to XXICC (21st Century Co-design) release 0.0q
Here is the release 0.0p of XXICC. There is no rev 0.0o since the letter O looks too much like the digit 0. 0.0p adds a Flavia implementation for the Gadget Factory Papilio DUO board, which has a Xilinx Spartan-6 LX9 FPGA and an Arduino-compatible Atmel ATmega32U4. Flavia 0.0p also adds pinout tables to map top-level ports and signal names to FPGA pins. You can also specify pull-up, pull-down, and keeper circuits for FPGA I/Os.
0.0p is a “partial” release specifically intended to support the author’s element14 ’blog Raspberry Pi 2 meets Papilio DUO. To get this ’blog published in a timely fashion, we chose to defer some features to next release: see the release notes.
XXICC (21st Century Co-design) is a not-for-profit research project which attempts to bring digital hardware/software co-design into the 21st Century using an improved programming language and a Reduced Software Complexity philosophy. Its goal is to make it easier and more enjoyable to write and maintain digital hardware and software. XXICC is pronounced "Chicken Coop", so-called because it has so many layers.
For an overview of XXICC, see the xxicc.org home page and wiki. For details on the GalaxC programming language, XXICC Object Editor, and GalaxC extensions for Hardware Design (GCHD), here are the latest documents and source code.

I've tested XXICC 0.0p on GNU/Linux (Ubuntu on x86 PC, Raspberry Pi Debian "Wheezy", and ODROID-C1 Ubuntu). My main machine is Ubuntu, so the others are more likely to have anomalies. Constructive comments and suggestions are most welcome. I'd especially like to find out how to reproduce some of the bugs that have been eluding me.
