| 3 | * Generator for RTL pass related boilerplate code/data | |
| 4 | * | |
| 5 | * Supports gcc 4.5-6 | |
| 6 | * | |
| 7 | * Usage: | |
| 8 | * | |
| 9 | * 1. before inclusion define PASS_NAME | |
| 10 | * 2. before inclusion define NO_* for unimplemented callbacks | |
| 11 | * NO_GATE | |
| 12 | * NO_EXECUTE | |
| 13 | * 3. before inclusion define PROPERTIES_* and TODO_FLAGS_* to override | |
| 14 | * the default 0 values | |
| 15 | * 4. for convenience, all the above will be undefined after inclusion! | |
| 16 | * 5. the only exported name is make_PASS_NAME_pass() to register with gcc | |
