Detailed Description
A generic binary operator: two inputs and one output.
All binary op-codes have a single data-type for input values 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.
Reimplemented in TypeOpIntSright, TypeOpIntRight, and TypeOpIntLeft.
◆ getOutputLocal()
◆ 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.
Reimplemented in TypeOpIntSright.
