[PATCH 10/10] Use rtx_insn for various jump-handling functions and predicates

David Malcolm dmalcolm@redhat.com
Fri Sep 5 01:47:00 GMT 2014


gcc/
	* config/arc/arc.c (arc_print_operand): Use insn method of
	final_sequence for type-safety.
	* config/bfin/bfin.c (bfin_hardware_loop): Strengthen param
	"insn" from rtx to rtx_insn *.
	* config/frv/frv.c (frv_print_operand_jump_hint): Likewise.
	* config/mn10300/mn10300.c (mn10300_scan_for_setlb_lcc):
	Likewise for locals "branch", "label".
	* config/h8300/h8300.c (same_cmp_preceding_p): Likewise for
	locals "i1", "i2".  Use NULL rather than NULL_RTX in comparisons.
	(same_cmp_following_p): Likewise for locals "i2", "i3".
	* config/sh/sh.c (gen_far_branch): Likewise for local "insn".
	* config/sh/sh_optimize_sett_clrt.cc
	(sh_optimize_sett_clrt::sh_cbranch_ccreg_value): Likewise for
	param "cbranch_insn".
	* function.c (convert_jumps_to_returns): Likewis for local "jump".
	* ifcvt.c (cond_exec_get_condition): Likewise for param "jump".
	* jump.c (simplejump_p): Strengthen param "insn" from const_rtx to
	const rtx_insn *.
	(condjump_p): Likewise.
	(condjump_in_parallel_p): Likewise.
	(pc_set): Likewise.
	(any_uncondjump_p): Likewise.
	(any_condjump_p): Likewise.
	(condjump_label): Likewise.
	(returnjump_p): Strengthen param "insn" from rtx to
	const rtx_insn *.
	(onlyjump_p): Strengthen param "insn" from const_rtx to
	const rtx_insn *.
	(jump_to_label_p): Likewise.
	(invert_jump_1): Strengthen param "jump" from rtx to rtx_insn *.
	(invert_jump): Likewise.
	* reorg.c (simplejump_or_return_p): Add checked cast when calling
	simplejump_p.
	(get_jump_flags): Strengthen param "insn" from rtx to
	const rtx_insn *.
	(get_branch_condition): Likewise.
	(condition_dominates_p): Likewise.
	(make_return_insns): Move declaration of local "pat" earlier, to
	after we've handled NONJUMP_INSN_P and non-sequences, using its
	methods to simplify the code and for type-safety.
	* rtl.h (find_constant_src): Strengthen param from const_rtx to
	const rtx_insn *.
	(jump_to_label_p): Strengthen param from rtx to const rtx_insn *.
	(condjump_p): Strengthen param from const_rtx to
	const rtx_insn *.
	(any_condjump_p): Likewise.
	(any_uncondjump_p): Likewise.
	(pc_set): Likewise.
	(condjump_label): Likewise.
	(simplejump_p): Likewise.
	(returnjump_p): Likewise.
	(onlyjump_p): Likewise.
	(invert_jump_1): Strengthen param 1 from rtx to rtx_insn *.
	(invert_jump): Likewise.
	(condjump_in_parallel_p): Strengthen param from const_rtx to
	const rtx_insn *.
	* rtlanal.c (find_constant_src): Strengthen param from const_rtx
	to const rtx_insn *.
	* sel-sched-ir.c (fallthru_bb_of_jump): Strengthen param from rtx
	to const rtx_insn *.
	* sel-sched-ir.h (fallthru_bb_of_jump): Likewise.
