>From the name it seems that it is trying to load a 8-bytes word atomically. We can't provide that on a 32-bit architecture, and I think other 32-bit architectures might have the same problem. Or maybe LLVM wrongly detects the machine as 64-bit (as it has a 64-bit kernel), and thus try to use 64-bit atomic functions. -- Aurelien Jarno GPG: 1024D/F1BCDB73 [email protected] http://www.aurel32.net -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
