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.
