The Type 3 opcodes are a subset of Type 2 opcodes that return an Integer value and can be used in
an expression that evaluates to a constant. These opcodes may be evaluated at ASL compile-time. To
ensure that these opcodes will evaluate to a constant, the following rules apply: The term cannot
have a destination (target) operand, and must have either a Type3Opcode, Type4Opcode, Type5Opcode,
ConstExprTerm, Integer, BufferTerm, Package, or String for all arguments.

The Type 4 opcodes are a subset of Type 2 opcodes that return a String value and can be used in an
expression that evaluates to a constant. These opcodes may be evaluated at ASL compile-time. To
ensure that these opcodes will evaluate to a constant, the following rules apply: The term cannot
have a destination (target) operand, and must have either a Type3Opcode, Type4Opcode, Type5Opcode,
ConstExprTerm, Integer, BufferTerm, Package, or String for all arguments.

The Type 5 opcodes are a subset of Type 2 opcodes that return a Buffer value and can be used in an
expression that evaluates to a constant. These opcodes may be evaluated at ASL compile-time. To
ensure that these opcodes will evaluate to a constant, the following rules apply: The term cannot
