I was going to say much the same thing. I don’t want to add that to the C++14 mix. I don’t even
know for sure that it’s a desirable change. I’ve worked on projects that got better (measured)
performance from -Os than from other global alternatives. One would need to do a bunch of
performance testing and might need to go more deeply into the options to really optimize things.
