------- Comment #6 from bonzini at gnu dot org  2007-11-30 10:59 -------
Looking at
http://physik.fu-berlin.de/~tburnus/gcc-trunk/benchmark/gfortran-run.dat and
http://physik.fu-berlin.de/~tburnus/gcc-trunk/benchmark/gfortranVecCost-run.dat
I think we should turn on cost model by default, at least for i386.

Uros?
