Relatedly, don't mess with the inferior's parentage. How would having a kernel based solution be better over your user space simulation? BTW there's the new signalfd() system call that might do it (haven't checked if it works for SIGCHLD) > * Support "displaced stepping" in the kernel; I think this would improve > performance when debugging in non-stop mode. Not sure what "displaced stepping" is exactly, but it sounds like the branch tracing extensions that got added a few releases ago? On modern Intel chips they give you a branch buffer in memory. -Andi -- ak@xxxxxxxxxxxxxxx -- Speaking for myself only. -- To unsubscribe from this list: send the line "unsubscribe linux-next" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
