Method Details

evaluateBinary

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

Description copied from class: BinaryOpBehavior

Evaluate the binary (2 input args) operation using long data

Specified by:

evaluateBinary in class BinaryOpBehavior

Parameters:

sizeout - intended output size (bytes)

sizein - in1 size (bytes)

in1 - unsigned input 1

in2 - unsigned input 2

Returns:

operation result. 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.
