            Bug ID: 63972
           Summary: shrink_wrap_symbol_ref_1.c fail with -mabi=ilp32 on
                    aarch64
           Product: gcc
           Version: 5.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: middle-end
          Assignee: unassigned at gcc dot gnu.org
          Reporter: pinskia at gcc dot gnu.org
            Target: aarch64

shrink_wrap_symbol_ref_1.c fails due to lo_sum not being able to remove.  It
was decided that we should special case lo_sum in the shrink wrapping code.

I have a patch to fix this which I will be submitting this weekend.
