Very likely, I suspect.

And the version of the euclid algo in that patch is better than most
references that I've seen.  (q=a/b;r=a%b; is common, probably because
the texts use the same algo for computing the continued fraction.)

In any case, I do not have the hardware to do any statistically
significant testing; the closest I could do would be a speed test
on hera, which I expect would be discouraged.
