Detailed Description
The following node type describes state automaton. The state may be deterministic or non-deterministic. Non-deterministic state has several component states which represent alternative cpu units reservations. The state also is used for describing a deterministic reservation of automaton insn.
Field Documentation
| automaton_t state::automaton |
The following field value is automaton to which given state
belongs.
Referenced by reserv_sets_are_intersected().
| alt_state_t state::component_states |
The following field is used to transform NDFA to DFA and DFA
minimization. The field value is not NULL if the state is a
compound state. In this case the value of field `unit_sets_list'
is NULL. All states in the list are in the hash table. The list
is formed through field `next_sorted_alt_state'. We should
support only one level of nesting state.

| int state::equiv_class_num_1 |
The two following fields are used during minimization of a finite
state automaton.

| state_t state::equiv_class_state |
The following field is used during minimization of a finite state
automaton. The field value is state corresponding to equivalence
class to which given state belongs.

| arc_t state::first_out_arc |
The following field value is the first arc output from given
state.
| char state::it_was_placed_in_stack_for_DFA_forming |
The following field is used to form DFA.
| char state::it_was_placed_in_stack_for_NDFA_forming |
The following field is used to form NDFA.
| int state::min_insn_issue_delay |
The following member is used to evaluate min issue delay of insn
for a state.
| int state::new_cycle_p |
The following member value is nonzero if there is a transition by
cycle advancing.

This member is used for passing states for searching minimal
delay time.
| int state::unique_num |
The following field is unique number of given state between other
states.
