++/* 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.
