    • try_split returns an rtx_insn · 53f04688 
      2014-08-21  David Malcolm  <dmalcolm@redhat.com>

	* rtl.h (try_split): Strengthen return type from rtx to rtx_insn *.

	* emit-rtl.c (try_split): Likewise, also for locals "before" and
	"after".  For now, don't strengthen param "trial", which requires
	adding checked casts when returning it.

    • Debug hooks: use rtx_insn and rtx_code_label · f630fc6a

	* debug.h (struct gcc_debug_hooks): Strengthen param 1 of hook
	"label" from rtx to rtx_code_label *.  Strengthen param 1 of
	"var_location" hook from rtx to rtx_insn *.
	(debug_nothing_rtx): Delete in favor of...
	(debug_nothing_rtx_code_label): New prototype.
	(debug_nothing_rtx_rtx): Delete unused prototype.
	(debug_nothing_rtx_insn): New prototype.

	* final.c (final_scan_insn): Add checked cast to rtx_insn * when
	invoking debug_hooks->var_location (in two places, one in a NOTE
	case of a switch statement, the other guarded by a CALL_P
	conditional.  Add checked cast to rtx_code_label * when invoking
	debug_hooks->label (within CODE_LABEL case of switch statement).

	* dbxout.c (dbx_debug_hooks): Update "label" hook from
	debug_nothing_rtx to debug_nothing_rtx_code_label.  Update
	"var_location" from debug_nothing_rtx to debug_nothing_rtx_insn.

    • Use rtx_insn internally within generated functions · 95770ca3 
      2014-08-21  David Malcolm  <dmalcolm@redhat.com>

	* recog.h (insn_output_fn): Update this function typedef to match
	the changes below to the generated output functions, strengthening
	the 2nd param from rtx to rtx_insn *.

	* final.c (get_insn_template): Add a checked cast to rtx_insn * on
	insn when invoking an output function, to match the new signature
	of insn_output_fn with a stronger second param.

	* genconditions.c (write_header): In the generated code for
	gencondmd.c, strengthen the global "insn" from rtx to rtx_insn *
	to match the other changes in this patch.

	* genemit.c (gen_split): Strengthen the 1st param "curr_insn" of
	the generated "gen_" functions from rtx to rtx_insn * within their
	implementations.

	* genrecog.c (write_subroutine): Strengthen the 2nd param "insn" of
	the subfunctions within the generated "recog_", "split", "peephole2"
	function trees from rtx to rtx_insn *.  For now, the top-level
	generated functions ("recog", "split", "peephole2") continue to
	take a plain rtx for "insn", to avoid introducing dependencies on
	other patches.  Rename this 2nd param from "insn" to
	"uncast_insn", and reintroduce "insn" as a local variable of type
	rtx_insn *, initialized at the top of the generated function with
	a checked cast on "uncast_insn".
	(make_insn_sequence): Strengthen the 1st param "curr_insn" of
	the generated "gen_" functions from rtx to rtx_insn * within their
	prototypes.

	* genoutput.c (process_template): Strengthen the 2nd param within
	the generated "output_" functions "insn" from rtx to rtx_insn *.
