+/* This file is compiled into assembly code which is then munged by a sed
+   script into two files: crti.s and crtn.s.
+
+   * crti.s puts a function prologue at the beginning of the .init and .fini
+   sections and defines global symbols for those addresses, so they can be
+   called as functions.
+
+   * crtn.s puts the corresponding function epilogues in the .init and .fini
+   sections.
+
+   This differs from what would be generated by the generic code in that
+   we save and restore the GP within the function.  In order for linker
+   relaxation to work, the value in the GP register on exit from a function
+   must be valid for the function entry point.  Normally, a function is
+   contained within one object file and this is not an issue, provided
+   that the function reloads the gp after making any function calls.
+   However, _init and _fini are constructed from pieces of many object
+   files, all of which may have different GP values.  So we must reload
+   the GP value from crti.o in crtn.o.  */

-#undef USE_TLS
-
-
-/* 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, firstcall)
-
-     This macro must initialize the thread pointer to enable normal TLS
-     operation.  The first parameter is a pointer to the thread control
-     block.  The second parameter specifies whether this is the first
-     call for the TCB.  ld.so calls this macro more than once.
-
-
-     THREAD_DTV()
-
-     This macro returns the address of the DTV of the current thread.
-     This normally is done using the the thread register which points
-     to the dtv or the TCB (from which the DTV can found).
