I'm not sure what you are referring to but the way the %gs register handling will be implemented on Linux/x86 is to have the kernel allocate a GDT entry and initialize the %gs register for it. Using the auxiliary vector size and address of the memory region will be communicated to the program. There is no memory allocated, though. -- ---------------. ,-. 1325 Chesapeake Terrace Ulrich Drepper \ ,-------------------' \ Sunnyvale, CA 94089 USA Red Hat `--' drepper at redhat.com `------------------------
