Detailed Description

A generic functional operator.

The operator takes one or more inputs (with the same data-type by default) and produces one output with specific data-type

Member Function Documentation

◆ getInputLocal()

Datatype * TypeOpFunc::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
opis the PcodeOp being considered
slotis the input being considered
Returns
the data-type

Reimplemented from TypeOp.

Reimplemented in TypeOpExtract, and TypeOpInsert.

◆ getOutputLocal()

Datatype * TypeOpFunc::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
opis the PcodeOp being considered
Returns
the data-type

Reimplemented from TypeOp.

◆ printRaw()

void TypeOpFunc::printRaw ( ostream &  s,
const PcodeOp op 
)
virtual

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

Parameters
sis the output stream
opis the specific PcodeOp to print

Implements TypeOp.
