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