Come on guys, what are you doing?
Code size at -Os has regressed by a whopping 5% over the last 2 days:

Os&data
view=Timeline&finish_button=Finish
But looking at todays results it looks like back to normal, I think
this is not
really a gcc bug but a linker one. The only thing which went in
yesterday which
could have even caused this was a patch which broke adding hidden
symbols into
libgcc but I fixed that today. So if tomorrow's results will show that
we
regressed again but this would mean the linker is not doing its job.
So in conclusion, this is not a gcc regression at all.
