I am testing patch fixing the Atom issues and other problems.
The gfortran.fortran-torture/execute/arrayarg.f90 testcase is however
different: the new inline code enables loop unrolling that in turn makes sched2
to produce wrong code. The testcase passes with -fno-unroll-loop (or a hack
disabling only RTL unroller) as well as with -fno-schedule-insns2 added.
After hours looking into the code produced I am quite convinced that the memset
expansion involved is correct. Can someone with better Fortran-fu than me
verify that the testcase is well defined WRT aliasing?
