             Bug #: 51860
           Summary: [4.7 regression] s390 esa mode bootstrap comparison
                    failure since transactional memory branch
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: critical
          Priority: P3
         Component: bootstrap
        AssignedTo: unassig...@gcc.gnu.org
        ReportedBy: kreb...@gcc.gnu.org


Since revision r181154 the ESA mode bootstrap fails on s390 with a bootstrap
comparison failure (the daily built builds with --with-mode=zarch).

The c_common_nodes_and_builtins function does seem to have a different size
comparing the two stages.

stage2: 83336 c_common_nodes_and_builtins()
stage3: 83528 c_common_nodes_and_builtins()

I have a closer look next week.
