Make tablejump_p accept a rtx_jump_table_data **

2014-08-19  David Malcolm  <dmalcolm@redhat.com>

	* rtl.h (tablejump_p): Strengthen third param from rtx * to
	rtx_jump_table_data **.

	* cfgbuild.c (make_edges): Introduce local "table", using it in
	place of "tmp" for jump table data.
	(find_bb_boundaries): Strengthen local "table" from rtx to
	rtx_jump_table_data *.
	* cfgcleanup.c (merge_blocks_move_successor_nojumps): Likewise.
	(outgoing_edges_match): Likewise for locals "table1" and "table2".
	(try_crossjump_to_edge): Likewise.
	* cfgrtl.c (try_redirect_by_replacing_jump): Likewise for local
	"table".
	(patch_jump_insn): Introduce local "table", using it in place of
	"tmp" for jump table data.
	(force_nonfallthru_and_redirect): Introduce local "table", so that
	call to tablejump_p can receive an rtx_jump_table_data **.  Update
	logic around the call to overwrite "note" appropriately if
	tablejump_p returns non-zero.
	(get_last_bb_insn): Introduce local "table", using it in place of
	"tmp" for jump table data.
	* dwarf2cfi.c (create_trace_edges): Likewise.

	* config/arm/arm.c (get_jump_table_size): Strengthen param "insn"
	from rtx to rtx_jump_table_data *.
	(create_fix_barrier): Strengthen local "tmp" from rtx to
	rtx_jump_table_data *.
	(arm_reorg): Likewise for local "table".

	* config/s390/s390.c (s390_chunkify_start): Likewise.

	* config/spu/spu.c (spu_emit_branch_hint): Likewise.

	* jump.c (delete_related_insns): Strengthen local "lab_next" from
	rtx to rtx_jump_table_data *.

	* rtlanal.c (tablejump_p): Strengthen param "tablep" from rtx * to
	rtx_jump_table_data **.  Add a checked cast when writing through
	the pointer: we know there that local "table" is non-NULL and that
	JUMP_TABLE_DATA_P (table) holds.
	(label_is_jump_target_p): Introduce local "table", using it in
	place of "tmp" for jump table data.
