Hello,
This is the second version patch to avoid remove the CTF section in
stripped files. Changes from v1:
- Add description in tests/run-strip-remove-keep-ctf.sh
mentioning how to regenerate test input file (testfile-ctf)
Please let me know your thoughts.
Kind regard,
guillermo
CTF debug format was designed to be present in stripped files, so
this section should not be removed, so a new --remove-ctf option
is added to indicate explicitly that .ctf section will be stripped
out from binary file.
