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