/* 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) against 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.
