As fas as I can tell, yes.
> If so try comparing numbers with --enable-checking=release.
I am more interested to compare times rather than get the lowest possible
number.
The following update of the timings shows that the compile time is
worsening without positive impact on the execution time:

I have done the following comparison of the compile time for induct.f90
with -ftime-report.
Half of the ~15s is coming from 'loop analysis' (7s) and 'expand' account for
1s.
Assuming that the lines starting by 'df' were introduced by the
'dataflow' patch, it can explain directly at most a few seconds.
Does anybody understand why 'loop analysis' takes so much time on Darwin7?
TIA
