Looking at the polyhedron benchmark data from
http://physik.fu-berlin.de/~tburnus/gcc-trunk/benchmark/, there appears to be a
big jump in performance in the induct runtime with -ffast-math and -O3 between
2008-04-24 and 2008-05-01. Unfortunately, there is a gap in the data between
those dates with the later showing the increase.
