Re: Severe increase in compilation time with 4.3.0 20070615 on powerpc-apple-darwin7


> Btw, is this a compiler with checking enabled?  

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

Dominique
