/* This file provides the startup routine for files loaded with
the -A option of GNU ld. When a program makes a call to the
initial address of code incrementally loaded, it expects that the
first function laid out in the object files loaded will
be the function called. In GNU C++, we slip crt1.o in front of
the object files the user specifies, so that we can call any needed
global constructors, and set up calls for global destructors.
Control is then passed to the first routine that the user specified. */
