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