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.
