When I analyzed this for the first time and finally found the root cause
my immediate reaction was "huh? we still have -fforce-addr?" . So, I also
wanted to get rid of it. But Richard had some reservations at that time
suspecting that it still has some performance implications sometimes.
But, I mean, nobody ever uses -fforce-addr consciously anymore. It's in
libtheoras Makefile just because some ancient version of gcc produced better
code with it, sometimes, perhaps.
So if we can agree to dump -fforce-addr: yes, please.
