gcc/ChangeLog:
2014-09-09 David Malcolm <dmalcolm@redhat.com>
* ira.c (ira_update_equiv_info_by_shuffle_insn): Use NULL rather
than NULL_RTX.
(no_equiv): Likewise.
(update_equiv_regs): Likewise.
(setup_reg_equiv): Likewise. Strengthen locals "elem",
"prev_elem", "next_elem" from rtx to rtx_insn_list *, and "insn"
from rtx to rtx_insn *. Use methods of "elem" for typesafety and
clarity.
* ira.h (struct ira_reg_equiv_s): Strengthen field "init_insns"
from rtx to rtx_insn_list *.
* lra-assigns.c (spill_for): Strengthen local "x" from rtx to
rtx_insn_list * and use methods for clarity and typesafety.
* lra-constraints.c (contains_deleted_insn_p): Likewise for param
"list".
(init_insn_rhs_dead_pseudo_p): Likewise for local "insns". Remove
redundant check on INSN_P (insns): this cannot hold, as "insns" is
an INSN_LIST, not an insn.
(reverse_equiv_p): Strengthen local "insns" from rtx to
rtx_insn_list * and use methods for clarity and typesafety.
(contains_reloaded_insn_p): Likewise for local "list".
