   3  * Generator for IPA 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_GENERATE_SUMMARY
  12  *    NO_READ_SUMMARY
  13  *    NO_WRITE_SUMMARY
  14  *    NO_READ_OPTIMIZATION_SUMMARY
  15  *    NO_WRITE_OPTIMIZATION_SUMMARY
  16  *    NO_STMT_FIXUP
  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!
  24  * 5. the only exported name is make_PASS_NAME_pass() to register with gcc
