Subject: [PATCH v3] strip: keep .ctf section in stripped file
Date: Thu, 23 Feb 2023 12:42:37 -0600	[thread overview]
Message-ID: <20230223184237.240615-1-guillermo.e.martinez@oracle.com> (raw)
In-Reply-To: <20220601155527.2192182-1-guillermo.e.martinez@oracle.com>

Hello,

This is the third version of the patch to avoid remove the CTF section in
stripped files. Changes from v2:

  - Rebased from master.

Please let me know your thoughts.

Kind regards,
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.
