            Bug ID: 63837
           Summary: [5 Regression] r217391 causes kernel build errors with
                    GCC_COMPARE_DEBUG=1
           Product: gcc
           Version: 5.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: driver
          Assignee: unassigned at gcc dot gnu.org
          Reporter: trippels at gcc dot gnu.org

cc1: all warnings being treated as errors
make[1]: *** [arch/powerpc/kernel/asm-offsets.s] Error 1

Without GCC_COMPARE_DEBUG=1 the kernel builds fine.
Started with r217391.
