| /** |
| * Test for static rewrites + IPA second chance compilation. |
| * |
| * The DML scripts contain more information, but essentially |
| * without a second chance of static rewrites + IPA after the initial |
| * pass of IPA, there are many situations in which sizes will remain |
| * unknown even after recompilation, thus leading to distributed ops. |
| * With the second chance enabled, sizes in these situations can be |
| * determined. For example, the alternation of constant folding |
| * (static rewrite) and scalar replacement (IPA) can allow for size |
| * propagation without dynamic rewrites or recompilation due to |
| * replacement of scalars with literals during IPA, which enables |
| * constant folding of sub-DAGs of literals during static rewrites, |
| * which in turn allows for scalar propagation during IPA. |
