Detailed Description
An injection payload that uses a Ghidra client to generate the p-code ops.
This acts as a placeholder for the actual details of the payload. When the inject() method is invoked, the context is wrapped as XML and sent to the Ghidra client, which returns the actual p-code to inject.
Member Function Documentation
◆ inject()
|
virtual |
Perform the injection of this payload into data-flow.
P-code operations representing this payload are copied into the controlling analysis context. The provided PcodeEmit object dictates exactly where the PcodeOp and Varnode objects are inserted and to what container. An InjectContext object specifies how placeholder elements become concrete Varnodes in the appropriate context.
- Parameters
-
context is the provided InjectConject object emit is the provovided PcodeEmit object
Implements InjectPayload.
◆ restoreXml()
|
inlinevirtual |
Restore this payload from an XML stream.
The base class version of this method restores from a <pcode> tag. Derived classes may restore from a parent tag and then invoke the base class method.
- Parameters
-
el is the XML element
Reimplemented from InjectPayload.
Reimplemented in InjectCallotherGhidra, and InjectCallfixupGhidra.
