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. -*/ -struct user_bfinfp_struct { -}; - -/* 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 r0, r1, r2, r3, r4, r5, r6, r7; - long p0, p1, p2, p3, p4, p5, usp, fp; - long i0, i1, i2, i3; - long l0, l1, l2, l3; - long b0, b1, b2, b3; - long m0, m1, m2, m3; - long a0w, a1w; - long a0x, a1x; - unsigned long rets; - unsigned long astat; - unsigned long pc; - unsigned long orig_p0; -}; - -/* 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 */ - -/* The rest of this junk is to help gdb figure out what goes where */ - unsigned long int u_tsize; /* Text segment size (pages). */ - unsigned long int u_dsize; /* Data segment size (pages). */ - unsigned long int u_ssize; /* Stack segment size (pages). */ - unsigned long start_code; /* Starting virtual address of text. */ - unsigned long start_stack; /* Starting virtual address of stack area. - This is actually the bottom of the stack, - the top of the stack is always found in the - esp register. */ - long int signal; /* Signal that caused the core dump. */ - int reserved; /* No longer used */ - unsigned long u_ar0; - /* Used by gdb to help find the values for */ - /* the registers. */ - unsigned long magic; /* To uniquely identify a core file */ - char u_comm[32]; /* User command that was responsible */ -}; -#define NBPG PAGE_SIZE -#define UPAGES 1 -#define HOST_TEXT_START_ADDR (u.start_code) -#define HOST_STACK_END_ADDR (u.start_stack + u.u_ssize * NBPG) - -#endif |
