* emit-rtl.h (copy_delay_slot_insn): Strengthen return type and
param from rtx to rtx_insn *.
* emit-rtl.c (copy_delay_slot_insn): Likewise.
* reorg.c (skip_consecutive_labels): Strengthen return type, param
and local "insn" from rtx to rtx_insn *.
(unfilled_slots_base): Strengthen type from rtx * to rtx_insn **.
(unfilled_slots_next): Likewise.
(function_return_label): Strengthen from rtx to rtx_code_label *.
(function_simple_return_label): Likewise.
(first_active_target_insn): Strengthen return type and param from
rtx to rtx_insn *.
(find_end_label): Strengthen return type from rtx to
rtx_code_label *; strengthen locals as appropriate.
(emit_delay_sequence): Strengthen return type, param "insn" and
local "seq_insn" from rtx to rtx_insn *. Strengthen param "list"
and local "li" from rtx to rtx_insn_list *, using methods of
rtx_insn_list for clarity and typesafety.
(add_to_delay_list): Strengthen return type and param "insn" from
rtx to rtx_insn *. Strengthen param "delay_list" from rtx to
rtx_insn_list * and use methods of rtx_insn_list.
(delete_from_delay_slot): Strengthen return type, param "insn",
locals "trial", "seq_insn", "prev" from rtx to rtx_insn *.
Strengthen local "seq" from rtx to rtx_sequence *, and local
"delay_list" from rtx to rtx_insn_list *, using methods of
rtx_sequence for clarity and type-safety.
(delete_scheduled_jump): Add checked cast when invoking
delete_from_delay_slot. Strengthen local "trial" from rtx to
rtx_insn *.
(optimize_skip): Strengthen return type and local "delay_list"
from rtx to rtx_insn_list *. Strengthen local "trial" from rtx to
rtx_insn *.
(steal_delay_list_from_target): Strengthen return type, param
"delay_list" and local "new_delay_list" from rtx to
rtx_insn_list *. Strengthen param "seq" from rtx to
rtx_sequence *. Strengthen param "pnew_thread" from rtx * to
rtx_insn **.
Split out local "temp" into multiple more-tightly scoped locals:
sometimes an rtx_insn_list *, and once a rtx_insn *. Use methods
of rtx_insn_list and rtx_sequence for clarity and typesafety.
Strengthen locals named "trial" from rtx to rtx_insn *.
(steal_delay_list_from_fallthrough): Strengthen return type and
param "delay_list" from rtx to rtx_insn_list *. Strengthen param
"seq" from rtx to rtx_sequence *. Use methods of rtx_sequence.
Strengthen local "trial" from rtx to rtx_insn *.
(try_merge_delay_insns): Strength local "merged_insns" from rtx
to rtx_insn_list * and use its methods. Strengthen local "pat"
from rtx to rtx_sequence * and use its methods. Strengthen locals
"dtrial" and "new_rtx" from rtx to rtx_insn *.
(get_label_before): Strengthen return type and local "label" from
rtx to rtx_insn *.
(fill_simple_delay_slots): Likewise for locals "insn", "trial",
"next_trial", "next", prev". Strengthen local "delay_list" from
rtx to rtx_insn_list * Strengthen local "tmp" from rtx * to
rtx_insn **.
(follow_jumps): Strengthen return type, param "label" and locals
"insn", "next", "value", "this_label" from rtx to rtx_insn *.
(fill_slots_from_thread): Strengthen return type, param
"delay_list" from rtx to rtx_insn_list *. Strengthen params
"insn", "thread", "opposite_thread" and locals "new_thread",
"trial", "temp", "ninsn" from rtx to rtx_insn *. Introduce local
"sequence" from a checked cast to rtx_sequence so that we can call
steal_delay_list_from_target and steal_delay_list_from_fallthrough
with an rtx_sequence *.
(fill_eager_delay_slots): Strengthen locals "insn", "target_label",
"insn_at_target", "fallthrough_insn" from rtx to rtx_insn *.
Strengthen local "delay_list" from rtx to rtx_insn_list *.
(relax_delay_slots): Strengthen param "first" and locals "insn",
"next", "trial", "delay_insn", "target_label" from rtx to
rtx_insn *. Strengthen local "pat" from rtx to rtx_sequence *.
Introduce a local "trial_seq" for PATTERN (trial) of type
rtx_sequence *, in both cases using methods of rtx_sequence.
(dbr_schedule): Strengthen param "first" and locals "insn",
"next", "epilogue_insn" from rtx to rtx_insn *.
