--- Comment #9 from Dominique d'Humieres <dominiq at lps dot ens.fr> 2011-01-26 10:23:12 UTC --- This pr is not fixed at revision 169261 (gfc). AFAIU -ftree-loop-linear is now implemented through graphite. This leads to a sort of regression with respect to revision 169227(gfc6): [macbook] lin/test% gfc -Ofast -ftree-loop-linear induct.f90 [macbook] lin/test% time a.out > /dev/null 22.380u 0.023s 0:22.40 100.0% 0+0k 0+0io 0pf+0w [macbook] lin/test% gfc6 -Ofast -ftree-loop-linear induct.f90 [macbook] lin/test% time a.out > /dev/null 13.978u 0.019s 0:13.99 99.9% 0+0k 0+0io 0pf+0w
