  5. * Core file format: The core file is written in such a way that gdb
  6. * can understand it and provide useful information to the user (under
  7. * linux we use the `trad-core' bfd). The file contents are as
  8. * follows:
  9. *
  10. * upage: 1 page consisting of a user struct that tells gdb
  11. * what is present in the file. Directly after this is a
  12. * copy of the task_struct, which is currently not used by gdb,
  13. * but it may come in handy at some point. All of the registers
  14. * are stored as part of the upage. The upage should always be
  15. * only one page long.
  16. * data: The data segment follows next. We use current->end_text to
  17. * current->brk to pick up all of the user variables, plus any memory
  18. * that may have been sbrk'ed. No attempt is made to determine if a
  19. * page is demand-zero or if a page is totally unused, we just cover
  20. * the entire range. All of the addresses are rounded in such a way
  21. * that an integral number of pages is written.
  22. * stack: We need the stack information in order to get a meaningful
  23. * backtrace. We need to write the data from usp to
  24. * current->start_stack, so we round each of these in order to be able
  25. * to write an integer number of pages.
