Hmm, this looks like a branch cost problem or related to that.
I think you can get all the speed back by supplying -mbranch-cost=1 but I could
be wrong.
Hmm, I wonder if 3.2.x was compiled for i486 (or i386) instead of i686 which
means this might not be
a regression.
Can you give the output of "gcc -v" for both GCC's?
