/* 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.
