gcc/ChangeLog:
2014-09-09  David Malcolm  <dmalcolm@redhat.com>

	* rtl.h (single_set_2): Strengthen first param from const_rtx to
	const rtx_insn *, and move prototype to above...
	(single_set): ...this.  Convert this from a macro to an inline
	function, enforcing the requirement that the param is a const
	rtx_insn *.
	(find_args_size_adjust): Strengthen param from rtx to rtx_insn *.

	* config/arm/aarch-common-protos.h (aarch_crypto_can_dual_issue):
	Strengthen both params from rtx to rtx_insn *.
	* config/arm/aarch-common.c (aarch_crypto_can_dual_issue):
	Likewise; introduce locals "producer_set", "consumer_set", using
	them in place of "producer" and "consumer" when dealing with SET
	rather than insn.
	* config/avr/avr.c (avr_out_plus): Add checked cast to rtx_insn *
	when invoking single_set in region guarded by INSN_P.
	(avr_out_bitop): Likewise.
	(_reg_unused_after): Introduce local rtx_sequence * "seq" in
	region guarded by GET_CODE check, using methods to strengthen
	local "this_insn" from rtx to rtx_insn *, and for clarity.
	* config/avr/avr.md (define_insn_and_split "xload8<mode>_A"):
	Strengthen local "insn" from rtx to rtx_insn *.
	(define_insn_and_split "xload<mode>_A"): Likewise.
	* config/bfin/bfin.c (trapping_loads_p): Likewise for param
	"insn".
	(find_load): Likewise for return type.
	(workaround_speculation): Likewise for both locals named
	"load_insn".
	* config/cris/cris.c (cris_cc0_user_requires_cmp): Likewise for
	local "cc0_user".
	* config/cris/cris.md (define_peephole2 ; moversideqi): Likewise
	for local "prev".
	* config/h8300/h8300-protos.h (notice_update_cc): Likewise for
	param 2.
	* config/h8300/h8300.c (notice_update_cc): Likewise.
	* config/i386/i386.c (ix86_flags_dependent): Likewise for params
	"insn" and "dep_insn".
	(exact_store_load_dependency): Likewise for both params.
	(ix86_macro_fusion_pair_p): Eliminate local named "single_set"
	since this now clashes with inline function.  Instead, delay
	calling single_set until the point where its needed, and then
	assign the result to "compare_set" and rework the conditional that
	follows.
	* config/ia64/ia64.md (define_expand "tablejump"): Strengthen
	local "last" from rtx to rtx_insn *.
	* config/mips/mips-protos.h (mips_load_store_insns): Likewise for
	second param.
	(mips_store_data_bypass_p): Likewise for both params.
	* config/mips/mips.c (mips_load_store_insns): Likewise for second
	param.
	(mips_store_data_bypass_p): Likewise for both params.
	(mips_orphaned_high_part_p): Likewise for param "insn".
	* config/mn10300/mn10300.c (extract_bundle): Likewise.
	(mn10300_bundle_liw): Likewise for locals "r", "insn1", "insn2".
	Introduce local rtx "insn2_pat".
	* config/rl78/rl78.c (move_elim_pass): Likewise for locals "insn",
	"ninsn".
	(rl78_remove_unused_sets): Likewise for locals "insn", "ninsn".
	Introduce local rtx "set", using it in place of "insn" for the
	result of single_set.  This appears to fix a bug, since the call
	to find_regno_note on a SET does nothing.
	* config/rs6000/rs6000.c (set_to_load_agen): Strengthen both
	params from rtx to rtx_insn *.
	(set_to_load_agen): Likewise.
	* config/s390/s390.c (s390_label_align): Likewise for local
	"prev_insn".  Introduce new rtx locals "set" and "src", using
	them in place of "prev_insn" for the results of single_set
	and SET_SRC respectively.
	(s390_swap_cmp): Strengthen local "jump" from rtx to rtx_insn *.
	Introduce new rtx local "set" using in place of "jump" for the
	result of single_set.  Use SET_SRC (set) rather than plain
	XEXP (set, 1).
	* config/sh/sh.c (noncall_uses_reg): Strengthen param 2from
	rtx to rtx_insn *.
	(noncall_uses_reg): Likewise.
	(reg_unused_after): Introduce local rtx_sequence * "seq" in region
	guarded by GET_CODE check, using its methods for clarity, and to
	enable strengthening local "this_insn" from rtx to rtx_insn *.
	* config/sh/sh.md (define_expand "mulhisi3"): Strengthen local
	"insn" from rtx to rtx_insn *.
	(define_expand "umulhisi3"): Likewise.
	(define_expand "smulsi3_highpart"): Likewise.
	(define_expand "umulsi3_highpart"): Likewise.
	* config/sparc/sparc.c (sparc_do_work_around_errata): Likewise for
	local "after".  Replace GET_CODE check with a dyn_cast,
	introducing new local rtx_sequence * "seq", using insn method for
	typesafety.

	* dwarf2cfi.c (dwarf2out_frame_debug): Strengthen param "insn"
	from rtx to rtx_insn *.  Introduce local rtx "pat", using it in
	place of "insn" once we're dealing with patterns rather than the
	input insn.
	(scan_insn_after): Strengthen param "insn" from rtx to rtx_insn *.
	(scan_trace): Likewise for local "elt", updating lookups within
	sequence to use insn method rather than element method.
	* expr.c (find_args_size_adjust): Strengthen param "insn" from rtx
	to rtx_insn *.
	* gcse.c (gcse_emit_move_after): Likewise for local "new_rtx".
	* ifcvt.c (noce_try_abs): Likewise for local "insn".
	* ira.c (fix_reg_equiv_init): Add checked cast to rtx_insn * when
	invoking single_set.
	* lra-constraints.c (insn_rhs_dead_pseudo_p): Strengthen param
	"insn" from rtx to rtx_insn *.
	(skip_usage_debug_insns): Likewise for return type, adding a
	checked cast.
	(check_secondary_memory_needed_p): Likewise for local "insn".
	(inherit_reload_reg): Likewise.
	* modulo-sched.c (sms_schedule): Likewise for local "count_init".
	* recog.c (peep2_attempt): Likewise for local "old_insn", adding
	checked casts.
	(store_data_bypass_p): Likewise for both params.
	(if_test_bypass_p): Likewise.
	* recog.h (store_data_bypass_p): Likewise for both params.
	(if_test_bypass_p): Likewise.
	* reload.c (find_equiv_reg): Likewise for local "where".
	* reorg.c (delete_jump): Likewise for param "insn".
	* rtlanal.c (single_set_2): Strenghen param "insn" from const_rtx
	to const rtx_insn *.
	* store-motion.c (replace_store_insn): Likewise for param "del".
	(delete_store): Strengthen local "i" from rtx to rtx_insn_list *,
	and use its methods for clarity, and to strengthen local "del"
	from rtx to rtx_insn *.
	(build_store_vectors): Use insn method of "st" when calling
	replace_store_insn for typesafety and clarity.
