Member Function Documentation

◆ evaluateUnary()

uintb OpBehaviorIntSext::evaluateUnary ( int4  sizeout,
int4  sizein,
uintb  in1 
) const
virtual

Emulate the unary op-code on an input value.

Parameters
sizeoutis the size of the output in bytes
sizeinis the size of the input in bytes
in1is the input value
Returns
the output value

Reimplemented from OpBehavior.

◆ recoverInputUnary()

uintb OpBehaviorIntSext::recoverInputUnary ( int4  sizeout,
uintb  out,
int4  sizein 
) const
virtual

Reverse the unary op-code operation, recovering the input value.

If the output value is known, recover the input value.

Parameters
sizeoutis the size of the output in bytes
outis the output value
sizeinis the size of the input in bytes
Returns
the input value

Reimplemented from OpBehavior.
