(Its meaning 35 depends on OPKIND.) */ 36 37/* Various macro used in OPERAND_VALUE: 38IMMEDIATE_s1: An immediate signed 1-byte value in the byte-code stream. 39IMMEDIATE_s2: An immediate signed 2-byte value in the byte-code stream. 40IMMEDIATE_u1: An immediate unsigned 1-byte value in the byte-code stream. 41IMMEDIATE_u2: An immediate unsigned 2-byte value in the byte-code stream. 42 43CONST_INDEX_1: An immediate unsigned 1-byte index into the constant pool. 44CONST_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 49BINOP: 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 55UNOP: unary operation 56 OPERAND_TYPE is the argument type. 57 OPERAND_VALUE is NEG. 58 59INVOKE: invoke operations 60 OPERAND_TYPE is VIRTUAL, SPECIAL, STATIC, or INTERFACE. 61 OPERAND_VALUE is 1 if interface, 0 otherwise. 62 63OBJECT: new, checkcast, instanceof 64 OPERAND_TYPE is PTR. 65 OPERAND_VALUE is NEW, CHECKCAST, or INSTANCEOF. 66 67BRANCH: 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 72STACK: Various stack operations. 73 74PUSHC: 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 79LOAD: 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 83CONVERT: 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 87TEST: 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 91COND: 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 95SWITCH: 96 OPERAND_VALUE is either TABLE or LOOKUP. 97 98ARRAY: 99 OPERAND_VALUE is LOAD, STORE, LENGTH, or NEW. 100 101FIELD: 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 105SPECIAL: 106 Random bunch of opcodes. 107 108*/ 109 110JAVAOP (nop, 0, STACK, POP, 0) 111JAVAOP (aconst_null, 1, PUSHC, PTR, 0) 112JAVAOP (iconst_m1, 2, PUSHC,
