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.
