Field Documentation
| ds_t _haifa_insn_data::check_spec |
What speculations are checked by this instruction.
| short _haifa_insn_data::cost |
| ds_t _haifa_insn_data::done_spec |
What speculations were already applied.
| int _haifa_insn_data::exact_tick |
For insns that are scheduled at a fixed difference from another,
this records the tick in which they must be ready.
| unsigned int _haifa_insn_data::fed_by_spec_load |
Set if there's DEF-USE dependence between some speculatively
moved load insn and this one.
| unsigned int _haifa_insn_data::feeds_backtrack_insn |
Nonzero if this insn has negative-cost forward dependencies against
an already scheduled insn.
| int _haifa_insn_data::inter_tick |
INTER_TICK is used to adjust INSN_TICKs of instructions from the
subsequent blocks in a region.
| unsigned int _haifa_insn_data::is_load_insn |
| int _haifa_insn_data::luid |
We can't place 'struct _deps_list' into h_i_d instead of deps_list_t
because when h_i_d extends, addresses of the deps_list->first
change without updating deps_list->first->next->prev_nextp. Logical uid gives the original ordering of the insns.
| int* _haifa_insn_data::max_reg_pressure |
The following array contains maximal reg pressure between last
scheduled insn and given insn. There is an element for each
pressure class of pseudos referenced in insns. This info updated
after scheduling each insn for each insn between the two
mentioned insns.
| int _haifa_insn_data::model_index |
| unsigned int _haifa_insn_data::must_recompute_spec |
Used internally in unschedule_insns_until to mark insns that must have
their TODO_SPEC recomputed.
| rtx _haifa_insn_data::orig_pat |
Original pattern of the instruction.
| rtx _haifa_insn_data::predicated_pat |
For insns with DEP_CONTROL dependencies, the predicated pattern if it
was ever successfully constructed.
| int _haifa_insn_data::priority |
A priority for each insn.
| signed char _haifa_insn_data::priority_status |
'> 0' if priority is valid,
'== 0' if priority was not yet computed,
'< 0' if priority in invalid and should be recomputed.
| int _haifa_insn_data::queue_index |
See comment on QUEUE_INDEX macro in haifa-sched.c.
Recovery block for speculation checks.
The following array contains info how the insn increases register
pressure. There is an element for each cover class of pseudos
referenced in insns.
| int _haifa_insn_data::reg_pressure_excess_cost_change |
Info about how scheduling the insn changes cost of register
pressure excess (between source and target).
The following list contains info about set pseudos and hard
registers available for allocation.
The following list contains info about used pseudos and hard
registers available for allocation.
| unsigned int _haifa_insn_data::shadow_p |
Nonzero if this insn is a shadow of another, scheduled after a fixed
delay. We only emit shadows at the end of a cycle, with no other
real insns following them.
| int _haifa_insn_data::tick |
The minimum clock tick at which the insn becomes ready. This is
used to note timing constraints for the insns in the pending list.
| int _haifa_insn_data::tick_estimate |
Used temporarily to estimate an INSN_TICK value for an insn given
current knowledge.
| ds_t _haifa_insn_data::todo_spec |
What speculations are necessary to apply to schedule the instruction.
