◆ getInputCast()

Datatype * TypeOpIntSless::getInputCast ( const PcodeOp op,
int4  slot,
const CastStrategy castStrategy 
) const
virtual

Find the data-type of the input to a specific PcodeOp.

Calculate the actual data-type of the input to the specific PcodeOp. A null result indicates the input data-type is the same as or otherwise doesn't need a cast from the data-type of the actual input Varnode

Parameters
opis the specific PcodeOp
slotis the input to consider
castStrategyis the current casting strategy
Returns
the data-type

Reimplemented from TypeOp.

◆ push()

virtual void TypeOpIntSless::push ( PrintLanguage lng,
const PcodeOp op,
const PcodeOp readOp 
) const
inlinevirtual

Push the specific PcodeOp to the emitter's RPN stack.

Given a specific language and PcodeOp, emit the expression rooted at the operation.

Parameters
lngis the PrintLanguage to emit
opis the specific PcodeOp
readOpis the PcodeOp consuming the output (or null)

Implements TypeOp.
