  26 /* These are bit masks and shift counts to use to access the various
  27    fields of an instruction.  To retrieve the X field of an
  28    instruction, use the expression
  29         (i >> OP_SH_X) & OP_MASK_X
  30    To set the same field (to j), use
  31         i = (i &~ (OP_MASK_X << OP_SH_X)) | (j << OP_SH_X)
  32
  33    Make sure you use fields that are appropriate for the instruction,
  34    of course.
  35
  36    The 'i' format uses OP, RS, RT and IMMEDIATE.
  37
  38    The 'j' format uses OP and TARGET.
  39
  40    The 'r' format uses OP, RS, RT, RD, SHAMT and FUNCT.
  41
  42    The 'b' format uses OP, RS, RT and DELTA.
  43
  44    The floating point 'i' format uses OP, RS, RT and IMMEDIATE.
  45
  46    The floating point 'r' format uses OP, FMT, FT, FS, FD and FUNCT.
  47
  48    A breakpoint instruction uses OP, CODE and SPEC (10 bits of the
  49    breakpoint instruction are not defined; Kane says the breakpoint
  50    code field in BREAK is 20 bits; yet MIPS assemblers and debuggers
  51    only use ten bits).  An optional two-operand form of break/sdbbp
  52    allows the lower ten bits to be set too, and MIPS32 and later
  53    architectures allow 20 bits to be set with a signal operand
  54    (using CODE20).
  55
  56    The syscall instruction uses CODE20.
  57
  58    The general coprocessor instructions use COPZ.  */
