    1.20 ++ * Core file format: The core file is written in such a way that gdb
    1.21 ++ * can understand it and provide useful information to the user (under
    1.22 ++ * linux we use the `trad-core' bfd).  The file contents are as follows:
    1.23 ++ *
    1.24 ++ *  upage: 1 page consisting of a user struct that tells gdb
    1.25 ++ *	what is present in the file.  Directly after this is a
    1.26 ++ *	copy of the task_struct, which is currently not used by gdb,
    1.27 ++ *	but it may come in handy at some point.  All of the registers
    1.28 ++ *	are stored as part of the upage.  The upage should always be
    1.29 ++ *	only one page long.
    1.30 ++ *  data: The data segment follows next.  We use current->end_text to
    1.31 ++ *	current->brk to pick up all of the user variables, plus any memory
    1.32 ++ *	that may have been sbrk'ed.  No attempt is made to determine if a
    1.33 ++ *	page is demand-zero or if a page is totally unused, we just cover
    1.34 ++ *	the entire range.  All of the addresses are rounded in such a way
    1.35 ++ *	that an integral number of pages is written.
    1.36 ++ *  stack: We need the stack information in order to get a meaningful
    1.37 ++ *	backtrace.  We need to write the data from usp to
    1.38 ++ *	current->start_stack, so we round each of these in order to be able
    1.39 ++ *	to write an integer number of pages.
