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. -*/ - -/* This is the old layout of "struct pt_regs" as of Linux 1.x, and - is still the layout used by user (the new pt_regs doesn't have - all registers). */ -struct user_regs_struct { - long er1, er2, er3, er4, er5, er6; - long er0; - long usp; - long orig_er0; - long ccr; - long pc; -}; - -/* When the kernel dumps core, it starts by dumping the user struct - - this will be used by gdb to figure out where the data and stack segments - are within the file, and what virtual addresses to use. */ -struct user { -/* We start with the registers, to mimic the way that "memory" is returned - from the ptrace(3,...) function. */ - struct user_regs_struct regs; /* Where the registers are actually stored */ -/* ptrace does not yet supply these.
