Ok.  We need to put this into "mips.h".  Thanks!

It should, if you define UNITS_PER_SIMD_WORD.

Thanks for writing this up. Would you please prepare also a patch to
http://gcc.gnu.org/gcc-4.0/changes.html mentioning this change? Moreover,
if
Gerald agrees, I think we could mention the PS/3D support in the front page
too
(http://gcc.gnu.org/news.html).

Does MIPS PS/3D work also with the autovectorizer?
