1) That no longer works with LLVM git master (the movq is no longer there, just a retq); 2) When I did similar tests IIRC I could get it to store the value (like you show in your example) but it still would not re-read the value so it would use the stale null pointer (despite the memory barrier), so unless your test also showed re-reading the pointer then the result would still be inconclusive. _______________________________________________ busybox mailing list busybox@busybox.net http://lists.busybox.net/mailman/listinfo/busybox
