+/*
+ * Generator for IPA pass related boilerplate code/data
+ *
+ * Supports gcc 4.5-6
+ *
+ * Usage:
+ *
+ * 1. before inclusion define PASS_NAME
+ * 2. before inclusion define NO_* for unimplemented callbacks
+ * NO_GENERATE_SUMMARY
+ * NO_READ_SUMMARY
+ * NO_WRITE_SUMMARY
+ * NO_READ_OPTIMIZATION_SUMMARY
+ * NO_WRITE_OPTIMIZATION_SUMMARY
+ * 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
