| 3 | * Generator for GIMPLE 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_GATE
|
| 12 | * NO_EXECUTE
|
| 13 | * 3. before inclusion define PROPERTIES_* and TODO_FLAGS_* to override
|
| 14 | * the default 0 values
|
| 15 | * 4. for convenience, all the above will be undefined after inclusion!
|
| 16 | * 5. the only exported name is make_PASS_NAME_pass() to register with gcc
