Detailed Description
Expression information.
Field Documentation
| BOOL_BITFIELD _expr::cant_move |
True when expression can't be moved.
| vec<expr_history_def> _expr::history_of_changes |
This vector contains the history of insn's transformations.
| BOOL_BITFIELD _expr::needs_spec_check_p |
True when this expression needs a speculation check to be scheduled. This is used during find_used_regs.
| int _expr::orig_bb_index |
A basic block index this was originated from. Zero when there is more than one originator.
| int _expr::orig_sched_cycle |
Cycle on which original insn was scheduled. Zero when it has not yet been scheduled or more than one originator.
| int _expr::priority |
A priority of this expression.
| int _expr::priority_adj |
A priority adjustment of this expression.
| int _expr::sched_times |
Number of times the insn was scheduled.
| int _expr::spec |
SPEC is the degree of speculativeness. FIXME: now spec is increased when an rhs is moved through a conditional, thus showing only control speculativeness. In the future we'd like to count data spec separately to allow a better control on scheduling.
| ds_t _expr::spec_done_ds |
Instruction should be of SPEC_DONE_DS type in order to be moved to this point.
| ds_t _expr::spec_to_check_ds |
SPEC_TO_CHECK_DS hold speculation types that should be checked (used only during move_op ()).
| signed char _expr::target_available |
True (1) when original target (register or memory) of this instruction is available for scheduling, false otherwise. -1 means we're not sure; please run find_used_regs to clarify.
| int _expr::usefulness |
Degree of speculativeness measured as probability of executing instruction's original basic block given relative to the current scheduling point.
| vinsn_t _expr::vinsn |
Insn description.
| BOOL_BITFIELD _expr::was_renamed |
True when the expression was renamed.
| BOOL_BITFIELD _expr::was_substituted |
True when the expression was substituted. Used for statistical purposes.
