sl@0: // Description:
sl@0: // toplevel initialization/destruction routines for 'user side' code compiled 
sl@0: // with the ARMCC EABI compiler. intended for static linking
sl@0: // The code supports 2.2 both bpabi and non-bpabi. The values in .init_array are
sl@0: // pointers in both environments, so the library is common to both.
sl@0: //

sl@0: // This calls each of the compiler constructed functions referenced from pi_ctorvec.
sl@0: // These functions arrange to 'call' the appropriate constructor for the 'static' instance
sl@0: // (in fact the call may be inlined). If the class of the instance has a destructor then 
sl@0: // compiler records that this object needs 'destructing' at 'exit' time. It does this by 
sl@0: // calling the function __cxa_atexit. We provide our own definition of this.
