1 /*
2  * Generator for IPA pass related boilerplate code/data
3  *
4  * Supports gcc 4.5-6
5  *
6  * Usage:
7  *
8  * 1. before inclusion define PASS_NAME
9  * 2. before inclusion define NO_* for unimplemented callbacks
10  *    NO_GENERATE_SUMMARY
11  *    NO_READ_SUMMARY
12  *    NO_WRITE_SUMMARY
13  *    NO_READ_OPTIMIZATION_SUMMARY
14  *    NO_WRITE_OPTIMIZATION_SUMMARY
15  *    NO_STMT_FIXUP
16  *    NO_FUNCTION_TRANSFORM
17  *    NO_VARIABLE_TRANSFORM
18  *    NO_GATE
19  *    NO_EXECUTE
20  * 3. before inclusion define PROPERTIES_* and *TODO_FLAGS_* to override
21  *    the default 0 values
22  * 4. for convenience, all the above will be undefined after inclusion!
23  * 5. the only exported name is make_PASS_NAME_pass() to register with gcc
