            Bug ID: 30241
           Summary: RFE add APIs to elfutis libdw
           Product: elfutils
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: general
          Assignee: unassigned at sourceware dot org
          Reporter: woodard at redhat dot com
                CC: elfutils-devel at sourceware dot org
  Target Milestone: ---

Please add new APIs to write DWARF. Some of the users could be dwz and dyninst.
One example would be:
https://github.com/dyninst/dyninst/issues/1401#issuecomment-1473826160 where
the problem is you relocate a function to instrument it but then the DWARF
backtraces are then wrong.

--- Comment #1 from Frank Ch. Eigler <fche at redhat dot com> ---
This depends largely on what sort of editing API a client envisions.
Writing brand new content from scratch is more like an assembler task.
Making micro edits in situ (changing individual DIEs, insert/delete, like a
text editor) is likely to be entirely different and much more complicated.

So ISTM this needs to be drive not by elfutils in the abstract but the specific
needs of the editing/synthesis tools.
