If CONFIG_CONSTUCTORS is enabled on a statically linked (CONFIG_STATIC_LINK=y) build of UML, the build fails due to the .eh_frame section being both used and discarded: ERROR:root:`.eh_frame' referenced in section `.text' of /usr/lib/gcc/x86_64-linux-gnu/11/crtbeginT.o: defined in discarded section `.eh_frame' of /usr/lib/gcc/x86_64-linux-gnu/11/crtbeginT.o `.eh_frame' referenced in section `.text' of /usr/lib/gcc/x86_64-linux-gnu/11/crtbeginT.o: defined in discarded section `.eh_frame' of /usr/lib/gcc/x86_64-linux-gnu/11/crtbeginT.o Instead, keep the .eh_frame section, as we do in dyn.lds.S for dynamically linked UML. This can be reproduced with: ./tools/testing/kunit/kunit.py run --kconfig_add CONFIG_STATIC_LINK=y --kconfig_add CONFIG_GCOV_KERNEL=y --kconfig_add CONFIG_DEBUG_FS=y Signed-off-by: David Gow <davidgow@google.com> Signed-off-by: Richard Weinberger <richard@nod.at>
