| /* JAVAOP (OPNAME, OPCODE, OPKIND, OPERAND_TYPE, OPERAND_VALUE), where: |
| OPNAME is the name of the opcode. |
| OPCODE is the 1-byte opcode value. |
| OPKIND is the kind of operation. |
| OPERAND_TYPE is the type operands affected. |
| OPERAND_VALUE tells where to get the value. (Its meaning |
| depends on OPKIND.) */ |
| |
| /* Various macro used in OPERAND_VALUE: |
| IMMEDIATE_s1: An immediate signed 1-byte value in the byte-code stream. |
| IMMEDIATE_s2: An immediate signed 2-byte value in the byte-code stream. |
| IMMEDIATE_u1: An immediate unsigned 1-byte value in the byte-code stream. |
| IMMEDIATE_u2: An immediate unsigned 2-byte value in the byte-code stream. |
| |
| CONST_INDEX_1: An immediate unsigned 1-byte index into the constant pool. |
| CONST_INDEX_2: An immediate unsigned 2-byte index into the constant pool. |
| */ |
| |
| /* More specifically, this is the meaning of the various OPKINDs: |
| |
| BINOP: binary operation |
| OPERAND_TYPE is the argument type. |
| OPERAND_VALUE is PLUS, MINUS, MULT, TRUNC_DIV, RDIV, REM, |
| LSHIFT, RSHIFT, URSHIFT, BIT_AND, BIT_IOR, BIT_XOR, |
| COMPARE, COMPARE_L, or COMPARE_G. |
| |
| UNOP: unary operation |
| OPERAND_TYPE is the argument type. |
| OPERAND_VALUE is NEG. |
| |
| INVOKE: invoke operations |
| OPERAND_TYPE is VIRTUAL, SPECIAL, STATIC, or INTERFACE. |
| OPERAND_VALUE is 1 if interface, 0 otherwise. |
| |
| OBJECT: new, checkcast, instanceof |
| OPERAND_TYPE is PTR. |
| OPERAND_VALUE is NEW, CHECKCAST, or INSTANCEOF. |
| |
| BRANCH: branch operations |
| OPERAND_TYPE is GOTO, CALL, or RETURN. |
| OPERAND_VALUE is IMMEDIATE_s2, VAR_INDEX_1, IMMEDIATE_s4, |
| or VAR_INDEX_2. |
| |
| STACK: Various stack operations. |
| |
| PUSHC: Push a constant onto the operand stack. |
| OPERAND_VALUE maybe be the value to push, |
| or IMMEDIATE_s1 or IMMEDIATE_s2 if the constant is immediate, |
| or CONST_INDEX_1 or CONST_INDEX_2 for a constant pool index. |
| |
| LOAD: Push a value from a local variable onto the operand stack. |
| OPERAND_VALUE is the index of the local variable in the current |
| Java frame. It can be a literal, or IMMEDIATE_i2. |
| |
| CONVERT: Convert top of stack value from one type to another. |
| OPERAND_TYPE is the argument type. |
| OPERAND_VALUE is the result type. |
| |
| TEST: Compares an integer (popped from the stack) against zero. |
| If the test (in OPERAND_VALUE) is true, goto a relative |
| offset given by the next two bytes. |
| |
| COND: Compares two values (popped from the stack) againt each other. |
| If the test (in OPERAND_VALUE) is true, goto a relative |
| offset given by the next two bytes. |
| |
| SWITCH: |
| OPERAND_VALUE is either TABLE or LOOKUP. |
| |
| ARRAY: |
| OPERAND_VALUE is LOAD, STORE, LENGTH, or NEW. |
| |
| FIELD: Extracts from or stores into a field. |
| OPERAND_TYPE is 1 for a static field, 0 for a regular field. |
| OPERAND_VALUE is 1 for a put operation, 0 for a get operation. |
| |
| SPECIAL: |
| Random bunch of opcodes. |
