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). There are quite a number of | ||
8 | obstacles to being able to view the contents of the floating point | ||
9 | registers, and until these are solved you will not be able to view the | ||
10 | contents of them. Actually, you can read in the core file and look at | ||
11 | the contents of the user struct to find out what the floating point | ||
12 | registers contain. | ||
13 | The actual file contents are as follows: | ||
14 | UPAGE: 1 page consisting of a user struct that tells gdb what is present | ||
15 | in the file. Directly after this is a copy of the task_struct, which | ||
16 | is currently not used by gdb, but it may come in useful at some point. | ||
17 | All of the registers are stored as part of the upage. The upage should | ||
18 | always be only one page. | ||
19 | DATA: The data area is stored. We use current->end_text to | ||
20 | current->brk to pick up all of the user variables, plus any memory | ||
21 | that may have been malloced. No attempt is made to determine if a page | ||
22 | is demand-zero or if a page is totally unused, we just cover the entire | ||
23 | range. All of the addresses are rounded in such a way that an integral | ||
24 | number of pages is written. | ||
25 | STACK: We need the stack information in order to get a meaningful | ||
26 | backtrace. We need to write the data from (esp) to | ||
27 | current->start_stack, so we round each of these off in order to be able | ||
28 | to write an integer number of pages. | ||
29 | The minimum core file size is 3 pages, or 12288 bytes. | ||
