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.
