In particular, after this patch, the first param passed to the
FINAL_PRESCAN_INSN macro is strengthened from rtx to rtx_insn *.
gcc/
* output.h (final_scan_insn): Strengthen return type from rtx to
rtx_insn *.
(final_forward_branch_p): Likewise for param.
(current_output_insn): Likewise for this global.
* final.c (rtx debug_insn): Likewise for this variable.
(current_output_insn): Likewise.
(get_attr_length_1): Rename param "insn" to "uncast_insn",
adding "insn" back in as an rtx_insn * with a checked cast, so
that macro ADJUST_INSN_LENGTH can be passed an rtx_insn * as the
first param.
(compute_alignments): Strengthen local "label" from rtx to
rtx_insn *.
(shorten_branches): Rename param from "first" to "uncast_first",
introducing a new local rtx_insn * "first" using a checked cast to
effectively strengthen "first" from rtx to rtx_insn * without
affecting the type signature. Strengthen locals "insn", "seq",
"next", "label" from rtx to rtx_insn *.
(change_scope): Strengthen param "orig_insn" and local "insn" from
rtx to rtx_insn *.
(final_start_function): Rename param from "first" to "uncast_first",
introducing a new local rtx_insn * "first" using a checked cast to
effectively strengthen "first" from rtx to rtx_insn * without
affecting the type signature. Strengthen local "insn" from rtx to
rtx_insn *.
(dump_basic_block_info): Strengthen param "insn" from rtx to
rtx_insn *.
(final): Rename param from "first" to "uncast_first",
introducing a new local rtx_insn * "first" using a checked cast to
effectively strengthen "first" from rtx to rtx_insn * without
affecting the type signature. Strengthen locals "insn", "next"
from rtx to rtx_insn *.
(output_alternate_entry_point): Strengthen param "insn" from rtx to
rtx_insn *.
(call_from_call_insn): Strengthen param "insn" from rtx to
rtx_call_insn *.
(final_scan_insn): Rename param from "insn" to "uncast_insn",
introducing a new local rtx_insn * "insn" using a checked cast to
effectively strengthen "insn" from rtx to rtx_insn * without
affecting the type signature. Strengthen return type and locals
"next", "note", "prev", "new_rtx" from rtx to rtx_insn *. Remove
now-redundant checked cast to rtx_insn * from both invocations of
debug_hooks->var_location. Convert CALL_P into a dyn_cast,
introducing a local "call_insn" for use when invoking
call_from_call_insn.
(notice_source_line): Strengthen param "insn" from rtx to
rtx_insn *.
(leaf_function_p): Likewise for local "insn".
(final_forward_branch_p): Likewise.
(leaf_renumber_regs): Likewise for param "first".
(rest_of_clean_state): Likewise for locals "insn" and "next".
(collect_fn_hard_reg_usage): Likewise for local "insn".
(get_call_fndecl): Likewise for param "insn".
(get_call_cgraph_rtl_info): Likewise.
(get_call_reg_set_usage): Rename param from "insn" to "uncast_insn",
introducing a new local rtx_insn * "insn" using a checked cast to
effectively strengthen "insn" from rtx to rtx_insn * without
affecting the type signature.
* config/arc/arc.c (arc_final_prescan_insn): For now, add checked
cast when assigning from param "insn" to current_output_insn.
(arc_pad_return): Strengthen local "insn" from rtx to rtx_insn *
so that we can assign it back to current_output_insn.
