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.
