There are in the moment two variants - available: - - * the thread pointer points to a thread control block - - * the thread pointer points to the dynamic thread vector - - - TLS_TCB_SIZE - - This is the size of the thread control block structure. How - this is actually defined depends on the ABI. The thread control - block could be internal descriptor of the thread library or - just a data structure which allows finding the DTV. - - TLS_INIT_TCB_SIZE - - Similarly, but this value is only used at startup and in the - dynamic linker itself. There are no threads in use at that time. - - - TLS_TCB_ALIGN - - Alignment requirements for the TCB structure. - - TLS_INIT_TCB_ALIGN - - Similarly, but for the structure used at startup time. - - - INSTALL_DTV(tcb, init_dtv) - - This macro must install the given initial DTV into the thread control - block TCB. The normal runtime functionality must then be able to - use the value. - - - TLS_INIT_TP(tcb) - - This macro must initialize the thread pointer to enable normal TLS - operation. The parameter is a pointer to the thread control block. - ld.so calls this macro once. - - - THREAD_DTV() - - This macro returns the address of the DTV of the current thread. - This normally is done using the thread register which points - to the dtv or the TCB (from which the DTV can found). - */ |
