Detailed Description
CPUI_INT_SUB behavior.
Member Function Documentation
◆ evaluateBinary()
|
virtual |
Emulate the binary op-code on input values.
- Parameters
-
sizeout is the size of the output in bytes sizein is the size of the inputs in bytes in1 is the first input value in2 is the second input value
- Returns
- the output value
Reimplemented from OpBehavior.
◆ recoverInputBinary()
|
virtual |
Reverse the binary op-code operation, recovering an input value.
If the output value and one of the input values is known, recover the value of the other input.
- Parameters
-
slot is the input slot to recover sizeout is the size of the output in bytes out is the output value sizein is the size of the inputs in bytes in is the known input value
- Returns
- the input value corresponding to the slot
Reimplemented from OpBehavior.
The documentation for this class was generated from the following files:
