(In reply to Richard Biener from comment #10)
> This should be fixed now.

I applied the commit r15-815-g5b9b3bae33cae to r15-518 and built
arith-rand-ll.c with -O2 -fno-delayed-branch -fno-ivopts -march=3Dv10 (like
above, to avoid ivopts and delayed-branch issues and the simulation numbers=
 are
even better than with r15-517:

Basic clock cycles, total @: 13653025
Memory source stall cycles: 78259

So, verified.

Thanks!
ps. I removed the testsuite-fail keyword as that belongs to PR115182.=
