// Name: __aeabi_atexit
//
// Description:
// Registers static object destructors. Normally atexit(f) should call
// __aeabi_atexit (NULL, f, NULL). But in the usage model here, static
// constructors are initialized at power up and are never destroyed
// because they have global scope and must persist for as long as the
// embedded device is powered on.
//
