-/* Core file format: The core file is written in such a way that gdb
-   can understand it and provide useful information to the user (under
-   linux we use the 'trad-core' bfd).  There are quite a number of
-   obstacles to being able to view the contents of the floating point
-   registers, and until these are solved you will not be able to view the
-   contents of them.  Actually, you can read in the core file and look at
-   the contents of the user struct to find out what the floating point
-   registers contain.
-   The actual file contents are as follows:
-   UPAGE: 1 page consisting of a user struct that tells gdb what is present
-   in the file.  Directly after this is a copy of the task_struct, which
-   is currently not used by gdb, but it may come in useful at some point.
-   All of the registers are stored as part of the upage.  The upage should
-   always be only one page.
-   DATA: The data area is stored.  We use current->end_text to
-   current->brk to pick up all of the user variables, plus any memory
-   that may have been malloced.  No attempt is made to determine if a page
-   is demand-zero or if a page is totally unused, we just cover the entire
-   range.  All of the addresses are rounded in such a way that an integral
-   number of pages is written.
-   STACK: We need the stack information in order to get a meaningful
-   backtrace.  We need to write the data from (esp) to
-   current->start_stack, so we round each of these off in order to be able
-   to write an integer number of pages.
-   The minimum core file size is 3 pages, or 12288 bytes.
