Member Function Documentation

getInputLocal()

Datatype * TypeOpCallother::getInputLocal ( const PcodeOp *  op, int4  slot  ) const

virtual

Find the minimal (or suggested) data-type of an input to this op-code.

The result should depend only on the op-code itself (and the size of the input)

Parameters

op	is the PcodeOp being considered
slot	is the input being considered

Returns

the data-type

Reimplemented from TypeOp.

getOperatorName()

string TypeOpCallother::getOperatorName ( const PcodeOp *  op ) const

virtual

Get the name of the op-code as it should be displayed in context.

Depending on the context, the same op-code may get displayed in different ways.

Parameters

op	is the PcodeOp context

Returns

the display token

Reimplemented from TypeOp.

getOutputLocal()

Datatype * TypeOpCallother::getOutputLocal ( const PcodeOp *  op ) const

virtual

Find the minimal (or suggested) data-type of an output to this op-code.

The result should depend only on the op-code itself (and the size of the output)

Parameters

op	is the PcodeOp being considered

Returns

the data-type

Reimplemented from TypeOp.

printRaw()

void TypeOpCallother::printRaw ( ostream &  s, const PcodeOp *  op  )

virtual

Print (for debugging purposes) this specific PcodeOp to the stream.

Parameters

s	is the output stream
op	is the specific PcodeOp to print

Implements TypeOp.

push()

virtual void TypeOpCallother::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

lng	is the PrintLanguage to emit
op	is the specific PcodeOp
readOp	is the PcodeOp consuming the output (or null)

Implements TypeOp.
