I'm not an expert, so I don't know. Maybe someone else could chime
in. One issue that I'd be interested in is to know whether GCC uses
this hint at some low optimization level, because I frequently need to
use -O1 or -O0 to get a binary I can debug without getting older by
the hour.

FWIW, the ones I put in some code I wrote long ago were not naive at
all. And I don't think those we have in Emacs are naive, either. But
if these hints are not used, it doesn't really matter.
