  29 /* JAVAOP (OPNAME, OPCODE, OPKIND, OPERAND_TYPE, OPERAND_VALUE), where:
  30         OPNAME is the name of the opcode.
  31         OPCODE is the 1-byte opcode value.
  32         OPKIND is the kind of operation.
  33         OPERAND_TYPE is the type operands affected.
  34         OPERAND_VALUE tells where to get the value.  (Its meaning
  35           depends on OPKIND.) */
  36
  37 /* Various macro used in OPERAND_VALUE:
  38 IMMEDIATE_s1:  An immediate signed 1-byte value in the byte-code stream.
  39 IMMEDIATE_s2:  An immediate signed 2-byte value in the byte-code stream.
  40 IMMEDIATE_u1:  An immediate unsigned 1-byte value in the byte-code stream.
  41 IMMEDIATE_u2:  An immediate unsigned 2-byte value in the byte-code stream.
  42
  43 CONST_INDEX_1:  An immediate unsigned 1-byte index into the constant pool.
  44 CONST_INDEX_2:  An immediate unsigned 2-byte index into the constant pool.
  45 */
  46
  47 /* More specifically, this is the meaning of the various OPKINDs:
  48
  49 BINOP:  binary operation
  50         OPERAND_TYPE is the argument type.
  51         OPERAND_VALUE is PLUS, MINUS, MULT, TRUNC_DIV, RDIV, REM,
  52           LSHIFT, RSHIFT, URSHIFT, BIT_AND, BIT_IOR, BIT_XOR,
  53           COMPARE, COMPARE_L, or COMPARE_G.
  54
  55 UNOP:   unary operation
  56         OPERAND_TYPE is the argument type.
  57         OPERAND_VALUE is NEG.
  58
  59 INVOKE: invoke operations
  60         OPERAND_TYPE is VIRTUAL, SPECIAL, STATIC, or INTERFACE.
  61         OPERAND_VALUE is 1 if interface, 0 otherwise.
  62
  63 OBJECT: new, checkcast, instanceof
  64         OPERAND_TYPE is PTR.
  65         OPERAND_VALUE is NEW, CHECKCAST, or INSTANCEOF.
  66
  67 BRANCH: branch operations
  68         OPERAND_TYPE is GOTO, CALL, or RETURN.
  69         OPERAND_VALUE is IMMEDIATE_s2, VAR_INDEX_1, IMMEDIATE_s4,
  70           or VAR_INDEX_2.
  71
  72 STACK:  Various stack operations.
  73
  74 PUSHC:  Push a constant onto the operand stack.
  75         OPERAND_VALUE maybe be the value to push,
  76         or IMMEDIATE_s1 or IMMEDIATE_s2 if the constant is immediate,
  77         or CONST_INDEX_1 or CONST_INDEX_2 for a constant pool index.
  78
  79 LOAD: Push a value from a local variable onto the operand stack.
  80         OPERAND_VALUE is the index of the local variable in the current
  81         Java frame.  It can be a literal, or IMMEDIATE_i2.
  82
  83 CONVERT: Convert top of stack value from one type to another.
  84         OPERAND_TYPE is the argument type.
  85         OPERAND_VALUE is the result type.
  86
  87 TEST: Compares an integer (popped from the stack) against zero.
  88         If the test (in OPERAND_VALUE) is true, goto a relative
  89         offset given by the next two bytes.
  90
  91 COND:  Compares two values (popped from the stack) againt each other.
  92         If the test (in OPERAND_VALUE) is true, goto a relative
  93         offset given by the next two bytes.
  94
  95 SWITCH:
  96         OPERAND_VALUE is either TABLE or LOOKUP.
  97
  98 ARRAY:
  99         OPERAND_VALUE is LOAD, STORE, LENGTH, or NEW.
 100
 101 FIELD: Extracts from or stores into a field.
 102         OPERAND_TYPE is 1 for a static field, 0 for a regular field.
 103         OPERAND_VALUE is 1 for a put operation, 0 for a get operation.
 104
 105 SPECIAL:
 106         Random bunch of opcodes.
