yes, that is correct, i.e. with the 4.4 branch the gfortran -fgraphite -c -O2 -ffast-math -funroll-loops -ftree-vectorize -march=native -ftime-report tmp.f90 command (thus including -fgraphite) takes about 4s seconds, while the same command line takes about 371s with 4.5. as explained by Sebastian in PR40965, this might be due to the fact that graphite recognizes now more loop constructs. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41193
