+ *
+ *    THEORY OF OPERATION
+ *
+ *    This version of thestartup code is intended for linker relocated
+ *    executables.  The startup code will assign the stack pointer to
+ *    __SP_INIT, assign the address of the data relative base address
+ *    to a5, initialize the .bss/.sbss sections to zero, call any
+ *    static C++ initializers and then call main.  Upon returning from
+ *    main it will call C++ destructors and call exit to terminate.
