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