Here it is, with `-O3 -march=native` and built in parallel:
{{{
All tests passed!
Total time for all tests: 4804.3 seconds
}}}
So, there is an improvement of 3% compared with my system's gcc without
optimization. That's not significant, but at least there is no slow-down.
I can say that this gcc spkg is an interesting contribution, and it works
for me. So, from my perspective, it is a positive review. However, I did
not test on a machine where the gcc spkg is really needed (OS X, for
example). Also, I am not sure if the vote on sage-devel on the inclusion
of another standard package has come to a clear conclusion.
Hence, I vote in favour of the spkg and insert my name as one reviewer,
but I do think that a second or third opinion is needed, which is why I do
not just change the ticket into a positive review.
