/* This file just make a stack frame for the contents of the .fini and
.init sections.  Users may put any desired instructions in those
sections.

While technically any code can be put in the init and fini sections
most stuff will not work other than stuff which obeys the call frame
and ABI. All the call-preserved registers are saved, the call clobbered
registers should have been saved by the code calling init and fini.

See crtstuff.c for an example of code that inserts itself in the 
init and fini sections. 

See crt0.s for the code that calls init and fini.
