 Hyperstone cpu emulator
 written by Pierpaolo Prazzoli

 All the types are compatible, but they have different IRAM size and cycles

 Hyperstone models:

 16 bits
 - E1-16T
 - E1-16XT
 - E1-16XS
 - E1-16XSR

 32bits
 - E1-32N   or  E1-32T
 - E1-32XN  or  E1-32XT
 - E1-32XS
 - E1-32XSR

 Hynix models:

 16 bits
 - GMS30C2116
 - GMS30C2216

 32bits
 - GMS30C2132
 - GMS30C2232

 TODO:
 - some wrong cycle counts
 - support more than 1 cpu when it'll be needed

 CHANGELOG:

 Pierpaolo Prazzoli
 - Fixed LDxx.N/P/S opcodes not to increment the destination register when
   it's the same as the source or "next source" one.

 Pierpaolo Prazzoli
 - Removed nested delays
 - Added better delay branch support
 - Fixed PC seen by a delay instruction, because a delay instruction
   should use the delayed PC (thus allowing the execution of software
   opcodes too)

 MooglyGuy 29/03/2004
    - Changed MOVI to use unsigned values instead of signed, correcting
      an ugly glitch when loading 32-bit immediates.
 Pierpaolo Prazzoli
    - Same fix in get_const

 MooglyGuy - 02/27/04
    - Fixed delayed branching
    - const_val for CALL should always have bit 0 clear

 Pierpaolo Prazzoli - 02/25/04
    - Fixed some wrong addresses to address local registers instead of memory
    - Fixed FRAME and RET instruction
    - Added preliminary I/O space
    - Fixed some load / store instructions

 Pierpaolo Prazzoli - 02/20/04
    - Added execute_exception function
    - Added FL == 0 always interpreted as 16

 Pierpaolo Prazzoli - 02/19/04
    - Changed the reset to use the execute_trap(reset) which should be right to set
      the initiale state of the cpu
    - Added Trace exception
    - Set of T flag in RET instruction
    - Set I flag in interrupts entries and resetted by a RET instruction
    - Added correct set instruction for SR

 Pierpaolo Prazzoli - 10/26/03
    - Changed get_lrconst to get_const and changed it to use the removed GET_CONST_RR
      macro.
    - Removed the High flag used in some opcodes, it should be used only in
      MOV and MOVI instruction.
    - Fixed MOV and MOVI instruction.
    - Set to 1 FP is SR register at reset.
      (From the doc: A Call, Trap or Software instruction increments the FP and sets FL
      to 6, thus creating a new stack frame with the length of 6 registers).

 MooglyGuy - 10/25/03
    - Fixed CALL enough that it at least jumps to the right address, no word
      yet as to whether or not it's working enough to return.
    - Added get_lrconst() to get the const value for the CALL operand, since
      apparently using immediate_value() was wrong. The code is ugly, but it
      works properly. Vampire 1/2 now gets far enough to try to test its RAM.
    - Just from looking at it, CALL apparently doesn't frame properly. I'm not
      sure about FRAME, but perhaps it doesn't work properly - I'm not entirely
      positive. The return address when vamphalf's memory check routine is
      called at FFFFFD7E is stored in register L8, and then the RET instruction
      at the end of the routine uses L1 as the return address, so that might
      provide some clues as to how it works.
    - I'd almost be willing to bet money that there's no framing at all since
      the values in L0 - L15 as displayed by the debugger would change during a
      CALL or FRAME operation. I'll look when I'm in the mood.
    - The mood struck me, and I took a look at SET_L_REG and GET_L_REG.
      Apparently no matter what the current frame pointer is they'll always use
      local_regs[0] through local_regs[15].

 MooglyGuy - 08/20/03
    - Added H flag support for MOV and MOVI
    - Changed init routine to set S flag on boot. Apparently the CPU defaults to
      supervisor mode as opposed to user mode when it powers on, as shown by the
      vamphalf power-on routines. Makes sense, too, since if the machine booted
      in user mode, it would be impossible to get into supervisor mode.

 Pierpaolo Prazzoli - 08/19/03
    - Added check for D_BIT and S_BIT where PC or SR must or must not be denoted.
      (movd, divu, divs, ldxx1, ldxx2, stxx1, stxx2, mulu, muls, set, mul
      call, chk)

 MooglyGuy - 08/17/03
    - Working on support for H flag, nothing quite done yet
    - Added trap Range Error for CHK PC, PC
    - Fixed relative jumps, they have to be taken from the opcode following the
      jump minstead of the jump opcode itself.

 Pierpaolo Prazzoli - 08/17/03
    - Fixed get_pcrel() when OP & 0x80 is set.
    - Decremented PC by 2 also in MOV, ADD, ADDI, SUM, SUB and added the check if
      D_BIT is not set. (when pc is changed they are implicit branch)

 MooglyGuy - 08/17/03
    - Implemented a crude hack to set FL in the SR to 6, since according to the docs
      that's supposed to happen each time a trap occurs, apparently including when
      the processor starts up. The 3rd opcode executed in vamphalf checks to see if
      the FL flag in SR 6, so it's apparently the "correct" behaviour despite the
      docs not saying anything on it. If FL is not 6, the branch falls through and
      encounters a CHK PC, L2, which at that point will always throw a range trap.
      The range trap vector contains 00000000 (CHK PC, PC), which according to the
      docs will always throw a range trap (which would effectively lock the system).
      This revealed a bug: CHK PC, PC apparently does not throw a range trap, which
      needs to be fixed. Now that the "correct" behaviour is hacked in with the FL
      flags, it reveals yet another bug in that the branch is interpreted as being
      +0x8700. This means that the PC then wraps around to 000082B0, give or take
      a few bytes. While it does indeed branch to valid code, I highly doubt that
      this is the desired effect. Check for signed/unsigned relative branch, maybe?

 MooglyGuy - 08/16/03
    - Fixed the debugger at least somewhat so that it displays hex instead of decimal,
      and so that it disassembles opcodes properly.
    - Fixed hyperstone_execute() to increment PC *after* executing the opcode instead of
      before. This is probably why vamphalf was booting to fffffff8, but executing at
      fffffffa instead.
    - Changed execute_trap to decrement PC by 2 so that the next opcode isn't skipped
      after a trap
    - Changed execute_br to decrement PC by 2 so that the next opcode isn't skipped
      after a branch
    - Changed hyperstone_movi to decrement PC by 2 when G0 (PC) is modified so that the
      next opcode isn't skipped after a branch
    - Changed hyperstone_movi to default to a UINT32 being moved into the register
      as opposed to a UINT8. This is wrong, the bit width is quite likely to be
      dependent on the n field in the Rimm instruction type. However, vamphalf uses
      MOVI G0,[FFFF]FBAC (n=$13) since there's apparently no absolute branch opcode.
      What kind of CPU is this that it doesn't have an absolute jump in its branch
      instructions and you have to use an immediate MOV to do an abs. jump!?
    - Replaced usage of logerror() with smf's verboselog()
