Detailed Description
Data references (or phi nodes that carry data reference values across loop iterations).
Field Documentation
| unsigned dref_d::always_accessed |
True if the memory reference is always accessed when the loop is entered.
Referenced by get_chain_root(), and order_drefs().
| unsigned dref_d::distance |
Distance of the reference from the root of the chain (in number of iterations of the loop).
Referenced by remove_name_from_operation(), and single_nonlooparound_use().
| tree dref_d::name_defined_by_phi |
In case that STMT is a phi node, this field is set to the SSA name defined by it in replace_phis_by_defined_names (in order to avoid pointing to phi node that got reallocated in the meantime).
Referenced by execute_pred_commoning_chain().
| double_int dref_d::offset |
Number of iterations offset from the first reference in the component.
| unsigned dref_d::pos |
Number of the reference in a component, in dominance ordering.
| struct data_reference* dref_d::ref |
The reference itself.
Referenced by get_chain_root(), and predcom_tmp_var().
| gimple dref_d::stmt |
The statement in that the reference appears.
Referenced by execute_pred_commoning_chain(), and single_nonlooparound_use().
