  11
  12         * interp.c (do_format_4): Get operands correctly and

  16
  17         * v850_sim.h: The V850 doesn't have split I&D spaces.  Change
  18         accordingly.  Remove many unused definitions.
  19         * interp.c: The V850 doesn't have split I&D spaces.  Change
  20         accordingly.
  21         (get_longlong, get_longword, get_word): Deleted.
  22         (write_longlong, write_longword, write_word): Deleted.
  23         (get_operands): Deleted.
  24         (get_byte, get_half, get_word): New functions.
  25         (put_byte, put_half, put_word): New functions.
  26         * simops.c: Remove unused functions.  Rough cut at
  27         "ld.b", "ld.h", "ld.w", "st.b", "st.h", "st.w" insns.
  28
  29         * v850_sim.h (struct _state): Remove "psw" field.  Add
  30         "sregs" field.
  31         (PSW): Remove bogus definition.
  32         * simops.c: Change condition code handling to use the psw
  33         register within the sregs array.  Handle "ldsr" and "stsr".
  34
  35         * simops.c: Handle "satadd", "satsub", "satsubi", "satsubr".
  36
  37         * interp.c (do_format_5): Get operands correctly and
  38         call the target function.
  39         (sim_resume): Don't do a PC update for format 5 instructions.
  40         * simops.c: Handle "jarl" and "jmp" instructions.
  41
  42         * simops.c: Fix minor typos.  Handle "cmp", "setf", "tst"
  43         "di", and "ei" instructions correctly.
  44
  45         * interp.c (do_format_3): Get operands correctly and call
  46         the target function.
  47         * simops.c: Handle bCC instructions.
  48
  49         * simops.c: Add condition code handling to shift insns.
  50         Fix minor typos in condition code handling for other insns.
  51
  52         * Makefile.in: Fix typo.
  53         * simops.c: Add condition code handling to "sub" "subr" and
  54         "divh" instructions.
  55
  56         * interp.c (hash): Update to be more accurate.
  57         (lookup_hash): Call hash rather than computing the hash
  58         code here.
  59         (do_format_1_2): Handle format 1 and format 2 instructions.
  60         Get operands correctly and call the target function.
  61         (do_format_6): Get operands correctly and call the target
  62         function.

  64         (sim_resume): Tweak to deal with format 1 and format 2
  65         handling in a single funtion.  Don't update the PC
  66         for format 3 insns.  Fix typos.
  67         * simops.c: Slightly reorganize.  Add condition code handling
  68         to "add", "addi", "and", "andi", "or", "ori", "xor", "xori"
  69         and "not" instructions.
  70         * v850_sim.h (reg_t): Registers are 32bits.
  71         (_state): The V850 has 32 general registers.  Add a 32bit
  72         psw and pc register too.  Add accessor macros
  73
  74         * Makefile.in, interp.c, v850_sim.h: Bring over endianness
  75         changes from the d10v simulator.
  76
  77         * simops.c: Add shift support.
  78
  79         * simops.c: Add multiply & divide support.  Abort for system
  80         instructions.
  81
  82         * simops.c: Add logicals, mov, movhi, movea, add, addi, sub
