> Here is the current results for 3.3.2 vs the mainline:
>                     -O0      -O1       -O2      -O3
> 3.3.2          28.93      42.81   61.13    58.140
> mainline     11.06      43.18   54.86    58.35

And more current results for the mainline on powerpc-darwin:
                      11.09      30.55    39.09   38.74

So it looks like this is fixed really and we are 40 % faster than 3.3.2 at -O1 on this testcase.
56% faster at -O2 and 50% at -O3. (which means we have caught back up to and past 3.0.4's number if 
the numbers in comment #0 scales the same on powerpc).

Someone should really do timings on x86 to make sure that they give about the same as powerpc.
