OP_INT_SUB

public static final OpBehaviorIntSub OP_INT_SUB

Method Details

values

public static OpBehaviorIntSub[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

an array containing the constants of this enum class, in the order they are declared

valueOf

public static OpBehaviorIntSub valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum class has no constant with the specified name

NullPointerException - if the argument is null

opcode

public int opcode()

Description copied from interface: OpBehavior

Returns the opcode implemented.

Specified by:

opcode in interface OpBehavior

Returns:

the opcode implemented

evaluateBinary

public long evaluateBinary(int sizeout,
 int sizein,
 long in1,
 long in2)

Description copied from interface: BinaryOpBehavior

Evaluate the binary operation using long data

NOTE: if the operation overflows bits may be set beyond the specified sizeout. Even though results should be treated as unsigned it may be returned as a signed long value. It is expected that the returned result always be properly truncated by the caller since the evaluation may not - this is done to conserve emulation cycles.

Specified by:

evaluateBinary in interface BinaryOpBehavior

Parameters:

sizeout - intended output size (bytes)

sizein - in1 size (bytes)

in1 - unsigned input 1

in2 - unsigned input 2

Returns:

operation result.

• Utils.bytesToLong(byte[], int, boolean)

evaluateBinary

public BigInteger evaluateBinary(int sizeout,
 int sizein,
 BigInteger in1,
 BigInteger in2)

Description copied from interface: BinaryOpBehavior

Evaluate the binary operation using BigInteger data

NOTE: if the operation overflows bits may be set beyond the specified sizeout. Even though results should be treated as unsigned it may be returned as a signed value. It is expected that the returned result always be properly truncated by the caller since the evaluation may not - this is done to conserve emulation cycles.

Specified by:

evaluateBinary in interface BinaryOpBehavior

Parameters:

sizeout - intended output size (bytes)

sizein - in1 size (bytes)

in1 - unsigned input 1

in2 - unsigned input 2

Returns:

operation result.
