opt_pass * opt_pass::clone ( )

virtualinherited

Create a copy of this pass.

Passes that can have multiple instances must provide their own implementation of this, to ensure that any sharing of state between this instance and the copy is "wired up" correctly.

The default implementation prints an error message and aborts.

Most passes are single-instance (within their context) and thus don't need to implement cloning, but passes that support multiple instances must provide their own implementation of the clone method.

Handle this by providing a default implemenation, but make it a fatal error to call it.

Referenced by add_pass_instance(), execute_fold_all_builtins(), and gate_copyrename().

unsigned int opt_pass::execute ( )

virtualinherited

This is the code to run. If has_execute is false, then there should be sub-passes otherwise this pass does nothing. The return value contains TODOs to execute in addition to those in TODO_flags_finish.

Referenced by execute_fold_all_builtins(), gate_check_data_deps(), gate_copyrename(), gate_tree_loop_vectorize(), gate_tree_ssa_loop_ivopts(), make_pass_graphite(), mark_operand_necessary(), replace_profitable_candidates(), rewrite_blocks(), rtl_loop_done(), rtl_loop_init(), tree_ssa_loop_bounds(), and tree_ssa_loop_done().

bool opt_pass::gate ( )

virtualinherited

If has_gate is set, this pass and all sub-passes are executed only if the function returns true. The default implementation returns true.
