GCC 11 with commit 6fbec038f7a7ddf29f074943611b53210d17c40c Author: H.J. Lu <hjl.tools@gmail.com> Date: Mon Feb 3 11:55:43 2020 -0800 Use SHF_GNU_RETAIN to preserve symbol definitions places used symbols in SECTION_RETAIN sections if assembler supports it. Mark __libc_freeres_fn as used to avoid gconv_dl.c: In function 'free_mem': gconv_dl.c:191:1: error: 'do_release_all' without 'used' attribute and 'free_mem' with 'used' attribute are placed in a section with the same name [-Werror=attributes] 191 | do_release_all (void *nodep) | ^~~~~~~~~~~~~~ In file included from <command-line>: gconv_dl.c:202:18: note: 'free_mem' was declared here 202 | libc_freeres_fn (free_mem) | ^~~~~~~~ ./../include/libc-symbols.h:316:15: note: in definition of macro 'libc_freeres_fn' 316 | static void name (void) | ^~~~ cc1: all warnings being treated as errors
