store-motion.c: Use rtx_insn
gcc/
2014-08-23 David Malcolm <dmalcolm@redhat.com>
* store-motion.c (store_killed_in_insn): Strengthen param "insn"
from const_rtx to const rtx_insn *.
(store_killed_after): Likewise. Strengthen locals "last", "act"
from rtx to rtx_insn *.
(store_killed_before): Strengthen param "insn" from const_rtx to
const rtx_insn *. Strengthen local "first" from rtx to rtx_insn *.
(find_moveable_store): Strengthen param "insn" from rtx to
rtx_insn *.
(compute_store_table): Likewise for local "insn".
(insert_insn_start_basic_block): Likewise for param "insn" and
locals "prev", "before", "insn".
(insert_store): For now, add a checked cast to rtx_insn * on the
result of gen_move_insn.
(remove_reachable_equiv_notes): Strengthen local "insn" from rtx
to rtx_insn *.
(replace_store_insn): Likewise. For now, add a checked cast to
rtx_insn * on the result of gen_move_insn.
