This time we ICE in rtx_addr_can_trap_p_1 because it assumes that all memory but BLKmode has known size. The patch just treats VOIDmode MEMs like BLKmode in that regard. And, the STRICT_ALIGNMENT change is needed because VOIDmode has GET_MODE_SIZE of 0 and we don't want to check if something is a multiple of 0. 2021-04-10 Jakub Jelinek <jakub@redhat.com> PR rtl-optimization/98601 * rtlanal.c (rtx_addr_can_trap_p_1): Allow in assert unknown size not just for BLKmode, but also for VOIDmode. For STRICT_ALIGNMENT unaligned_mems handle VOIDmode like BLKmode. * gcc.dg/torture/pr98601.c: New test. (cherry picked from commit 7a493fcd27d6a1af896c4f5ef4ab1e0afe8a839d)
