* 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
