Field Documentation
| bool ivopts_data::body_includes_call |
Whether the loop body includes any function calls.
Referenced by rewrite_use_compare().

Whether to consider just related and important candidates when replacing a
use.
Referenced by iv_ca_add_use().
| struct loop* ivopts_data::current_loop |
