It now + takes the array member name and the index as parameters. + (THREAD_SETMEM_NC): Likewise. + * pthread_getspecific.c: Use new THREAD_GETMEM_NC interface. + * pthread_setspecific.c: Use new THREAD_GETMEM_NC and THREAD_SETMEM_NC + interfaces. + + * sysdeps/i386/tls.h (THREAD_SETMEM): Use size of member element + to decide which code to use. + (THREAD_SETMEM_NC): Likewise. + * allocatestack.c (queue_stack): Don't remove stack from list here.
