There is some slight improvement since 2015-09-08:
before:
#> a
17.848000000000003 10.239999999999871
#> grep "number of SCoPs" a.f90.124t.graphite
number of SCoPs: 0
number of SCoPs: 2
after:
#> a
15.847999999999999 10.239999999999871
#> grep "number of SCoPs" a.f90.121t.graphite
number of SCoPs: 0
number of SCoPs: 1
which also gives a testsuite warning on my box:
XPASS: gfortran.dg/graphite/pr14741.f90 -O scan-tree-dump-times graphite
"number of SCoPs: 1" 1
