48 + * Core file format: The core file is written in such a way that gdb
49 + * can understand it and provide useful information to the user (under
50 + * linux we use the `trad-core' bfd). The file contents are as follows:
51 + *
52 + * upage: 1 page consisting of a user struct that tells gdb
53 + * what is present in the file. Directly after this is a
54 + * copy of the task_struct, which is currently not used by gdb,
55 + * but it may come in handy at some point. All of the registers
56 + * are stored as part of the upage. The upage should always be
57 + * only one page long.
58 + * data: The data segment follows next. We use current->end_text to
59 + * current->brk to pick up all of the user variables, plus any memory
60 + * that may have been sbrk'ed. No attempt is made to determine if a
61 + * page is demand-zero or if a page is totally unused, we just cover
62 + * the entire range. All of the addresses are rounded in such a way
63 + * that an integral number of pages is written.
64 + * stack: We need the stack information in order to get a meaningful
65 + * backtrace. We need to write the data from usp to
66 + * current->start_stack, so we round each of these in order to be able
67 + * to write an integer number of pages.
