| * Usage: | |

| * 1. before inclusion define PASS_NAME | |
| * 2. before inclusion define NO_* for unimplemented callbacks | |

| * NO_STMT_FIXUP | |
| * NO_FUNCTION_TRANSFORM | |
| * NO_VARIABLE_TRANSFORM | |
| * NO_GATE | |
| * NO_EXECUTE | |
| * 3. before inclusion define PROPERTIES_* and *TODO_FLAGS_* to override | |
| * the default 0 values | |
| * 4. for convenience, all the above will be undefined after inclusion! | |
| * 5. the only exported name is make_PASS_NAME_pass() to register with gcc | |
