--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Can you: s390*-*-linux*) - if test x$ac_cv_sizeof_void_p = x4; then - UNSUPPORTED=1 - fi in libsanitizer/configure.tgt and retry? As I said on the mailing list, I don't have any longer a way (at least not easy) to test 31-bit s390, which is why I haven't enabled it because I couldn't test it. If it works, then those 3 lines should be dropped. If it doesn't work, we'll need to figure out something (such as extending the asan_shadow_offset hook so that target can signal to toplev.c the lack of asan support even in a different way than having the hook NULL. Either through a magic value, or extra argument).
