Detailed Description
A user defined p-code op that has a dynamically defined procedure.
The behavior of this op on constant inputs can be dynamically defined. This class defines a unify() method that picks out the input varnodes to the operation, given the root PcodeOp. The input varnodes would generally just be the input varnodes to the raw CALLOTHER after the constant id, but skipping, reordering, or other tree traversal is possible.
This class also defines an execute() method that computes the output given constant inputs (matching the format determined by unify()).
Member Function Documentation
◆ execute()
|
pure virtual |
Compute the output value of this operation, given constant inputs.
- Parameters
-
input is the ordered list of constant inputs
- Returns
- the resulting value as a constant
Implemented in ghidra::SegmentOp.
◆ unify()
|
pure virtual |
Gather the formal input Varnode objects given the root PcodeOp.
- Parameters
-
data is the function being analyzed op is the root operation bindlist will hold the ordered list of input Varnodes
- Returns
- true if the requisite inputs were found
Implemented in ghidra::SegmentOp.
