You need to at least add entries to the relevant sections in extend.texi 
for the new target-specific intrinsic and attributes.  The documentation 
there doesn't need to be terribly detailed (one sentence and a link to 
the external document is probably all you need), but it's important that 
these things be listed in GCC's supported extensions so that users know 
they can use them and so that people who see them in code written by 
other people can find out what they mean.
