Hmm, on the 4.6 branch this seems fixed, trunk it is no longer tree-reassoc
that makes us slow, but instead with tree-reassoc things are faster ...
4.5 -O3 -ffast-math 1583.48
4.5 -O3 -ffast-math -fno-tree-reassoc 2307.55
4.6 -O3 -ffast-math 2287.99
4.6 -O3 -ffast-math -fno-tree-reassoc 2268.77
4.7 -O3 -ffast-math 1529.65
4.7 -O3 -ffast-math -fno-tree-reassoc 1144.00
4.7 -O3 -ffast-math -fno-tree-reassoc -fno-tree-vectorize 1992.50
Huh.
On the 4.6 branch we somehow avoided scheduling everything down by
tree reassoc, but on the 4.7 branch we are back to doing so.
It would be interesting to bisect what fixed it for 4.6 and what broke
it again for 4.7, even without reassociation.
With -fschedule-insns -fsched-pressure we get back to 2212.98 for 4.7.
With -fno-tree-reassoc we now vectorize the loop(!):

Would be interesting to look at it again in 4.8 with Richard's new
pressure-aware scheduling. I think there was some other patch that could be
used to enable -fschedule-insns on register-starved machines, so it would be
worthwhile doing a round of SPEC benchmarking with different options, on both
x86-32 and x86-64...

It'd be interesting to get some new timings, with the new register-pressure
aware scheduling and with LRA. Oh, and maybe with the patch to restrain the
reassoc pass a bit (http://gcc.gnu.org/ml/gcc-patches/2012-10/msg02122.html).

Bug 50557 looks like the same issue or at least a related one and it is
mentioned that LRA fixes the register allocation issue. So yes it would be
good to get new numbers for the trunk.

Is there any improvement if you use -fschedule-insns1 -fsched-pressure?
