The GCC back-end is now integrated with GCC 3.0 and now passes all of the
appropriate tests in the Mercury test suite. So it's basically ready for an
official release. Here's an update for the web page.
----------
Estimated hours taken: 2
Branches: main
w3/download/include/gcc-backend.inc:
Update to reflect recent changes:
- Tabling and nested modules now supported
- Mercury 0.10 and 0.10.1 released
- GCC 3.0 released, and now supported by Mercury's GCC back-end
Mention that the sources can be obtained via CVS.
w3/information/developers/remote_cvs.html:
Mention the "gcc/mercury" module.
