3672 + * Core file format: The core file is written in such a way that gdb
3673 + * can understand it and provide useful information to the user (under
3674 + * linux we use the `trad-core' bfd, NOT the osf-core).  The file contents
3675 + * are as follows:
3676 + *
3677 + *  upage: 1 page consisting of a user struct that tells gdb
3678 + *     what is present in the file.  Directly after this is a
3679 + *     copy of the task_struct, which is currently not used by gdb,
3680 + *     but it may come in handy at some point.  All of the registers
3681 + *     are stored as part of the upage.  The upage should always be
3682 + *     only one page long.
3683 + *  data: The data segment follows next.  We use current->end_text to
3684 + *     current->brk to pick up all of the user variables, plus any memory
3685 + *     that may have been sbrk'ed.  No attempt is made to determine if a
3686 + *     page is demand-zero or if a page is totally unused, we just cover
3687 + *     the entire range.  All of the addresses are rounded in such a way
3688 + *     that an integral number of pages is written.
3689 + *  stack: We need the stack information in order to get a meaningful
3690 + *     backtrace.  We need to write the data from usp to
3691 + *     current->start_stack, so we round each of these in order to be able
3692 + *     to write an integer number of pages.
