This change is incorrect. Floating point is not an adjective here.
It is probably best to just rewrite this text, of course. Maybe
"%qs requires quad-precision floating-point arithmetic" or something
like that (that it was first introduced in Power ISA 3.0 is dated
already, for example).

This change is trivial and obviously correct. Please just commit such
changes, *not* mixed in with anything else though. (And if you aren't
sure something is trivial or obviously correct, it is not!)

Your patch is malformed. Please fix your mailer.

The instances of the warning where floating point is at the end
of a message aren't correct. The warning should be relaxed to
allow unhyphenated floating point as a noun (as discussed briefly
last March:
https://gcc.gnu.org/pipermail/gcc-patches/2021-March/566881.html)
Wouldn't it be fair to say that “floating point” in the message above is
really an adjective modifying an implicit noun? The floating (decimal)
point doesn't itself have 128 bits.
Like you say in the linked message, we could add an explicit noun too.
But the change seems OK as-is to me.
I agree you could say that too. I didn't mean what I said as
an objection to the change but more as an observation that it
shouldn't be necessary (and an acknowledgment that I haven't
yet done what I said I'd do).
Martin
Thanks,
Richard
