Summary: [4.9 Regression] FAIL:
gfortran.dg/vect/fast-math-mgrid-resid.f
scan-tree-dump-times optimized "vect_[^\\n]*\\+ " 13
Product: gcc
Version: 4.9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3

The test gfortran.dg/vect/fast-math-mgrid-resid.f fails after r203979 if gcc is
configured with --with-cpu=core* (default for darwin). This is silenced if
-mtune=generic is added to the dg-options list:
