Nit: The above new @smallexample section and its associated description should
be
placed after this @findex vec_srdb (otherwise it breaks the connection between
the
index and the content of vec_srdb), but personally I preferred it to be placed
at
the end of this node, that is: after
"int vec_any_le (vector unsigned __int128, vector unsigned __int128);
@end smallexample
" as what's in your previous version, since most of these beginning entries have
their headings but this @smallexample section doesn't have a heading, it looks a
bit weird.

As Peter pointed out in another thread, you need int128 effective target check
as well,
otherwise it will fail with power10 -m32.
Another nit: power10_hw should already guarantee power10_ok, so power10_ok
is only required for dg-do link.
