Detailed Description
The data stored for each invariant.
Field Documentation
| bool invariant::always_executed |
Whether it is always executed.
Referenced by get_inv_cost(), and may_assign_reg_p().
| bool invariant::cheap_address |
Whether the invariant is cheap when used as an address.
Referenced by find_defs().
| unsigned invariant::cost |
Cost of the invariant.
Referenced by find_defs().
| struct def* invariant::def |
The definition of the invariant.
Referenced by find_invariant_insn(), get_inv_cost(), and may_assign_reg_p().
| bitmap invariant::depends_on |
The invariants it depends on.
Referenced by find_invariants_to_move().
| unsigned invariant::eqto |
The number of the invariant with the same value.
Referenced by find_invariants_to_move(), gain_for_invariant(), and invariant_for_use().
| rtx invariant::insn |
The insn in that it is defined.
Referenced by find_invariants_to_move(), and get_inv_cost().
| unsigned invariant::invno |
The number of the invariant.
Referenced by find_invariants_to_move(), and gain_for_invariant().
| bool invariant::move |
Whether to move the invariant.
Referenced by find_invariants_to_move(), and gain_for_invariant().
| int invariant::orig_regno |
If we moved the invariant out of the loop, the original regno
that contained its value.
| rtx invariant::reg |
If we moved the invariant out of the loop, the register that contains its
value.
Referenced by find_invariants_to_move().
| unsigned invariant::stamp |
Used for detecting already visited invariants during determining
costs of movements.
