Note, while it does not fully close the gap, I can confirm that a large portion of this the poor performance is a regression when compared to GCC 4.0.3. The 4.0.3 is about 1/3 faster than the 4.2.0 which also corresponds to a significantly reduced number of generated instructions for the inner loop. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=29543
