Detailed Description
A generic unary operator: one input and one output.
All unary op-codes have data-type for the input value and a data-type for the output value
Member Function Documentation
◆ getInputLocal()
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.
References TypeFactory::getBase(), PcodeOp::getIn(), Varnode::getSize(), metain, and TypeOp::tlst.
◆ getOutputLocal()
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.
References TypeFactory::getBase(), PcodeOp::getOut(), Varnode::getSize(), metaout, and TypeOp::tlst.
◆ printRaw()
|
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.
