--- Comment #1 from Segher Boessenkool <segher at gcc dot gnu.org> ---
Interesting! I tried it out, and indeed xxlor is 2 cycles while fmr is 6,
on p8 and p7, it's not just a documentation artefact. Apparently fmr goes
through the FP pipeline (while it doesn't have to, of course -- well it
may be easier to implement "fmr." this way, even that isn't needed).
It does not normally matter very much, but still. Confirmed.
