--- Comment #4 from ktkachov at gcc dot gnu.org ---
I'm still bisecting, but I suspect two recent commits to lra-constraints:

r206938

    2014-01-22  Vladimir Makarov  <vmakarov@redhat.com>

        PR rtl-optimization/59477
        * lra-constraints.c (inherit_in_ebb): Process call for living hard
        regs.  Update reloads_num and potential_reload_hard_regs for all
        insns.


and
r206908

    2014-01-21  Vladimir Makarov  <vmakarov@redhat.com>

        PR rtl-optimization/59896
        * lra-constraints.c (process_alt_operands): Check unused note for
        matched operands of insn with no output reloads.
