| // pound_assert tests is that the "limit exceeded" here diagnostic can vary |
| // depending on the codegen since we are using an arbitrary limit of 512. If the |
| // codegen changes, the line where we stop evaluating can change meaning that |
| // the note moves around lines. With FileCheck we have more flexibility to just |
| // match what we actually want. |
