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

17 * NO_FUNCTION_TRANSFORM
18 * NO_VARIABLE_TRANSFORM
19 * NO_GATE
20 * NO_EXECUTE
21 * 3. before inclusion define PROPERTIES_* and *TODO_FLAGS_* to override
22 * the default 0 values
23 * 4. for convenience, all the above will be undefined after inclusion!
