Depending on the ++ * processor core, the only instructions that might need to be emulated ++ * are div, divu, mul, muli, mulxss, mulxsu, and mulxuu. ++ * ++ * The emulations match the instructions, except for the following ++ * limitations: ++ * ++ * 1) The emulation routines do not emulate the use of the exception ++ * temporary register (et) as a source operand because the exception ++ * handler already has modified it. ++ * ++ * 2) The routines do not emulate the use of the stack pointer (sp) or the ++ * exception return address register (ea) as a destination because ++ * modifying these registers crashes the exception handler or the ++ * interrupted routine. ++ * ++ * Detailed Design ++ * --------------- ++ * ++ * The emulation routines expect the contents of integer registers r0-r31 ++ * to be on the stack at addresses sp, 4(sp), 8(sp), ... 124(sp). The ++ * routines retrieve source operands from the stack and modify the ++ * destination register's value on the stack prior to the end of the ++ * exception handler. Then all registers except the destination register ++ * are restored to their previous values. ++ * ++ * The instruction that causes the exception is found at address -4(ea). ++ * The instruction's OP and OPX fields identify the operation to be ++ * performed. ++ * ++ * One instruction, muli, is an I-type instruction that is identified by ++ * an OP field of 0x24. ++ * ++ * muli AAAAA,BBBBB,IIIIIIIIIIIIIIII,-0x24- ++ * 27 22 6 0 <-- LSB of field ++ * ++ * The remaining emulated instructions are R-type and have an OP field ++ * of 0x3a.

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_m68kfp_struct { ++ unsigned long fpregs[8*3]; /* fp0-fp7 registers */ ++ unsigned long fpcntl[3]; /* fp control regs */ ++}; ++ ++/* This is needs more work, probably should look like gdb useage */ ++struct user_regs_struct { ++ long r1,r2,r3,r4,r5,r6,r7,r8; ++ long r9,r10,r11,r12,r13,r14,r15; ++ long r16,r17,r18,r19,r20,r21,r22,r23; ++ long gp; ++ long sp; ++ long ra; ++ long fp; ++ long orig_r2; ++ long estatus; ++ long status_extension; ++ long ea; ++}; ++ ++ ++/* 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.
