17 | /* Core file format: The core file is written in such a way that gdb | ||
18 | * can understand it and provide useful information to the user (under | ||
19 | * linux we use the 'trad-core' bfd). There are quite a number of | ||
20 | * obstacles to being able to view the contents of the floating point | ||
21 | * registers, and until these are solved you will not be able to view | ||
22 | * the contents of them. Actually, you can read in the core file and | ||
23 | * look at the contents of the user struct to find out what the | ||
24 | * floating point registers contain. | ||
25 | * | ||
26 | * The actual file contents are as follows: | ||
27 | * UPAGE: | ||
28 | * 1 page consisting of a user struct that tells gdb what is present | ||
29 | * in the file. Directly after this is a copy of the task_struct, | ||
30 | * which is currently not used by gdb, but it may come in useful at | ||
31 | * some point. All of the registers are stored as part of the | ||
32 | * upage. The upage should always be only one page. | ||
33 | * | ||
34 | * DATA: | ||
35 | * The data area is stored. We use current->end_text to | ||
36 | * current->brk to pick up all of the user variables, plus any | ||
37 | * memory that may have been malloced. No attempt is made to | ||
38 | * determine if a page is demand-zero or if a page is totally | ||
39 | * unused, we just cover the entire range. All of the addresses are | ||
40 | * rounded in such a way that an integral number of pages is | ||
41 | * written. | ||
42 | * | ||
43 | * STACK: | ||
44 | * We need the stack information in order to get a meaningful | ||
45 | * backtrace. We need to write the data from (esp) to | ||
46 | * current->start_stack, so we round each of these off in order to | ||
47 | * be able to write an integer number of pages. The minimum core | ||
48 | * file size is 3 pages, or 12288 bytes. | ||
49 | */ | ||

18 | * A: At some points, the sum (%0) was used as | ||
19 | * length-counter instead of the length counter | ||
20 | * (%1). Thanks to Roman Hodek for pointing this out. | ||
21 | * B: GCC seems to mess up if one uses too many | ||
22 | * data-registers to hold input values and one tries to | ||
23 | * specify d0 and d1 as scratch registers. Letting gcc | ||
24 | * choose these registers itself solves the problem. | ||
