--- Comment #19 from Christophe Lyon <clyon at gcc dot gnu.org> --- (In reply to nsz from comment #18) > it's not a bug in the sense that the arm architecture > allows trap support (it's just not required), but it's > buggy that it would not report the support correctly > (e.g. enabling traps always succeed under qemu but > traps don't happen if the underlying hw has no support) OK, that was my suspicion. So, it seems hard to report a bug against qemu, then.
