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 |
