> Here is the current results for 3.3.2 vs the mainline:

> 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.
