It's a hybrid between ia64 and sparc64. I think you can use the ia64 datastructures, but I think the thread-pointer points to the TCB, not the TLS block as for ia64. How exactly depends on what the compiler emits. Our in-tree gcc does not emit TLS access sequences, so I wouldn't worry too much about it. I think the gcc port has been updated, so we can check if that one has TLS support on alpha. -- Marcel Moolenaar USPA: A-39004 marcel@xcllnt.net
