| # The problem on Alpha at -O3 is that when dd is inlined, we have |

| # The problem is that the multiplication was unsigned SImode, and the |
| # induction variable is DImode, and we lose the truncation that |
| # should have happened. |

| # On tree-ssa branch, the loop problem is still extant, but the |

| # to see that the comparisons are always true, and so the loop code |
