+/* An architecture-specific version of this file has to defined a
+   number of symbols:
+
+     TLS_TCB_AT_TP  or  TLS_DTV_AT_TP
+
+     The presence of one of these symbols signals which variant of
+     the TLS ABI is used.  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).
+
+
+     THREAD_GSCOPE_IN_TCB
+
+     This should be set to 1 if the global scope flag is stored within the TCB.
+     When set to 0, GL(_dl_thread_gscope_count) will be defined to store it.

-#include <lowlevellock-futex.h>
-
-/* Low-level locks use a combination of atomic operations (to acquire and
-   release lock ownership) and futex operations (to block until the state
-   of a lock changes).  A lock can be in one of three states:
-   0:  not acquired,
-   1:  acquired with no waiters; no other threads are blocked or about to block
-       for changes to the lock state,
-   >1: acquired, possibly with waiters; there may be other threads blocked or
-       about to block for changes to the lock state.
-
-   We expect that the common case is an uncontended lock, so we just need
-   to transition the lock between states 0 and 1; releasing the lock does
-   not need to wake any other blocked threads.  If the lock is contended
-   and a thread decides to block using a futex operation, then this thread
-   needs to first change the state to >1; if this state is observed during
-   lock release, the releasing thread will wake one of the potentially
-   blocked threads.
-
-   Much of this code takes a 'private' parameter.  This may be:
-   LLL_PRIVATE: lock only shared within a process
-   LLL_SHARED:  lock may be shared across processes.
-
-   Condition variables contain an optimization for broadcasts that requeues
-   waiting threads on a lock's futex.  Therefore, there is a special
-   variant of the locks (whose name contains "cond") that makes sure to
-   always set the lock state to >1 and not just 1.
-
-   Robust locks set the lock to the id of the owner.  This allows detection
-   of the case where the owner exits without releasing the lock.  Flags are
-   OR'd with the owner id to record additional information about lock state.
-   Therefore the states of robust locks are:
-    0: not acquired
-   id: acquired (by user identified by id & FUTEX_TID_MASK)
-
-   The following flags may be set in the robust lock value:
-   FUTEX_WAITERS     - possibly has waiters
-   FUTEX_OWNER_DIED  - owning user has exited without releasing the futex.  */

+
+   The following code tries hard to be optimal.  A general assumption
+   (which is true according to the data books I have) is that
+
+	2 * xchg	is more expensive than	pushl + movl + popl
+
+   Beside this a neat trick is used.  The calling conventions for Linux
+   tell that among the registers used for parameters %ecx and %edx need
+   not be saved.  Beside this we may clobber this registers even when
+   they are not used for parameter passing.
+
+   As a result one can see below that we save the content of the %ebx
+   register in the %edx register when we have less than 3 arguments
+   (2 * movl is less expensive than pushl + popl).
+
+   Second unlike for the other registers we don't save the content of
+   %ecx and %edx when we have more than 1 and 2 registers resp.
+
+   The code below might look a bit long but we have to take care for
+   the pipelined processors (i586).  Here the `pushl' and `popl'
+   instructions are marked as NP (not pairable) but the exception is
+   two consecutive of these instruction.  This gives no penalty on
+   other processors though.  */
