// 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.
|
