    1.17 +// toplevel initialization/destruction routines for 'user side' code compiled 
    1.18 +// with the ARMCC EABI compiler. intended for static linking
    1.19 +// 
    1.20 +//

    1.23 +
    1.24 +// This calls each of the compiler constructed functions referenced from pi_ctorvec.
    1.25 +// These functions arrange to 'call' the appropriate constructor for the 'static' instance
    1.26 +// (in fact the call may be inlined). If the class of the instance has a destructor then 
    1.27 +// compiler records that this object needs 'destructing' at 'exit' time. It does this by 
    1.28 +// calling the function __cxa_atexit. We provide our own definition of this.
    1.29 +// 
    1.30 +// This is the EABI compliant version - it uses .init_array rather than C$$pi_ctorvec
    1.31 +// which means we need to do via assembler :-(
