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