            Bug ID: 31083
           Summary: Improve compatibility with objects without DT_NEEDED
                    dependencies
           Product: glibc
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: dynamic-link
          Assignee: unassigned at sourceware dot org
          Reporter: fweimer at redhat dot com
  Target Milestone: ---

The changes in bug 17645 for dependency sorting may place objects without
dependencies differently. As a result, underlinked objects with implicit
dependencies on libc.so.6 may be relocated before libc.so.6, resulting in
relocation failures or crashes when IFUNC resolvers in libc.so.6 are invoke=
d.

It should be possible to relocate libc.so.6 earlier, so that it is already
relocated when those IFUNC resolvers are invoked.
