| ## Ensure that per-page compact encodings (indexes 127 and greater) |

| ## TODO(gkm): The input is a binary object file constructed from a |
| ## large generated assembler file. For sake of expediency and |
| ## test-time performance, I am following the unfortunate precedent |
| ## that MachO test inputs are binary. |
| ## |
| ## Non-MachO tests largely use YAML inputs. As I understand it, the |
| ## rationale is that these MachO tests were written prior to |
| ## availability of sufficiently-expressive YAML processors. |
| ## |
| ## I consider YAML a submoptimal input format. Better would be |
| ## assembler language inputs convertable to binary via llvm-mc. In |
| ## the case of this test however, the input is very large and the |
| ## overhead of llvm-mc is terrible (~10s) on a debug build. Overhead |
| ## for a release build of llvm-mc is acceptable at ~1s. It would be |
| ## good if there were a way to prefer an installed version of llvm-mc |
| ## to process tests in debug build trees when not testing llvm-mc |
| ## itself. |
