Comment(by howarth@…):

 Keep in mind that currently graphite is of little use in gcc 4.5.x. Only
 in gcc 4.6 are we finally approaching the point where -fgraphite-identity
 doesn't actually degrade the vectorization achieved...

 http://gcc.gnu.org/ml/gcc-patches/2010-08/msg00159.html

 Also currently the higher level graphite optimizations don't achieve any
 improvements, however once the vectorization loses are eliminated for
 -fgraphite-identity that option might yield a few percent improvement.

 vs
 http://gcc.gnu.org/ml/gcc-testresults/2010-08/msg00556.html

 shows the missed vectorization on using -fgraphite-identity (which
 converts the gimple to polyhedral represemtations and then back again to
 gimple (hopefully providing a more accurate representation of the loops
 than the original gimple).
