--- Comment #10 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-13 branch has been updated by Jakub Jelinek <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:35ac28b9c26debcc8ec8b247d75d4d271de72189 commit r13-8791-g35ac28b9c26debcc8ec8b247d75d4d271de72189 Author: Jakub Jelinek <ja...@redhat.com> Date: Wed May 22 09:12:28 2024 +0200 ubsan: Use right address space for MEM_REF created for bool/enum sanitization [PR115172] The following testcase is miscompiled, because -fsanitize=bool,enum creates a MEM_REF without propagating there address space qualifiers, so what should be normally loaded using say %gs:/%fs: segment prefix isn't. Together with asan it then causes that load to be sanitized. 2024-05-22 Jakub Jelinek <ja...@redhat.com> PR sanitizer/115172 * ubsan.cc (instrument_bool_enum_load): If rhs is not in generic address space, use qualified version of utype with the right address space. Formatting fix. * gcc.dg/asan/pr115172.c: New test. (cherry picked from commit d3c506eff54fcbac389a529c2e98da108a410b7f)
