The failure above was observed with r200057. Here the cc1 output:

            Bug ID: 57604
           Summary: LRA related bootstrap comparison failure on s390x
                    --with-arch=zEC12
           Product: gcc
           Version: 4.9.0
            Status: UNCONFIRMED
          Severity: major
          Priority: P3
         Component: bootstrap
          Assignee: unassigned at gcc dot gnu.org
          Reporter: krebbel at gcc dot gnu.org

Comparing stages 2 and 3
warning: gcc/cc1-checksum.o differs
warning: gcc/cc1plus-checksum.o differs
Bootstrap comparison failure!
gcc/tree-ssa-loop-im.o differs

stage2:

    .align    2
    .type    _ZZN19ref_always_accessedclEP11mem_ref_locE12__FUNCTION__, @object
    .size    _ZZN19ref_always_accessedclEP11mem_ref_locE12__FUNCTION__, 11
_ZZN19ref_always_accessedclEP11mem_ref_locE12__FUNCTION__:
    .string    "operator()"

stage3:

    .align    2
    .type    _ZZN19ref_always_accessedclEP11mem_ref_locE12__FUNCTION__, @object
    .size    _ZZN19ref_always_accessedclEP11mem_ref_locE12__FUNCTION__, 12
_ZZN19ref_always_accessedclEP11mem_ref_locE12__FUNCTION__:
    .string    "operator ()"


Be aware of the additional blank in the string. This does not happen when
disabling LRA for bootstrap.
