Date: Fri, 14 Jul 2017 15:29:00 -0000 Message-Id: <1500046110-20483-1-git-send-email-mark@klomp.org> X-Mailer: git-send-email 1.8.3.1 X-IsSubscribed: yes X-SW-Source: 2017-q3/txt/msg00007.txt.bz2 Adds two new output options: --keep-section=SECTION Keep the named section. SECTION is an extended wildcard pattern. May be given more than once. --remove-section=SECTION Remove the named section. SECTION is an extended wildcard pattern. May be given more than once. Only non-allocated sections can be removed. The --remove-section was already partially implemented, but only for the .comment section. The short option -R is to be compatible with binutils. The new testcase makes sure that various combinations of kept/removed sections pull the correct dependencies into the output and/or debug files.
