            Bug ID: 32692
           Summary: Add new add-minidebug binary
           Product: debugedit
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: debugedit
          Assignee: unassigned at sourceware dot org
          Reporter: mark at klomp dot org
                CC: debugedit at sourceware dot org
  Target Milestone: ---

Currently find-debuginfo has an add_minidebug function that uses readelf, awk,
nm (twice), sort, comm, xz and objcopy (twice) to extract and readd (some)
symbols as a compressed ELF image in a separate (.gnu_debugdata) section.

This is fragile and depending on how binutils was compiled prevents cross-arch
symbol manipulation.

It would be better and more efficient to implement this as a simple executable
based on elfutils libelf which is arch agnostic by default.
