22 * Beware that resume now expects *next to be in d1 and the offset of

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