Since Richard looked at the machine description part of the port, I looked at the other pieces. I'm happy with those pieces with the following minor changes:
http://gcc.gnu.org/ml/gcc-patches/2013-09/msg00520.html (libgcc): remove the .file directive from crtzero.S. See <http://gcc.gnu.org/ml/gcc-patches/2008-07/msg00123.html> for why such directives are best avoided. http://gcc.gnu.org/ml/gcc-patches/2013-09/msg00522.html (documentation): use @deftypefn rather than @table @code when documenting built-in functions. In install.texi, say @samp{newlib} and @samp{mculib} instead of using '' quotes. -- Joseph S. Myers jos...@codesourcery.com
