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()

void InjectPayloadGhidra::inject ( InjectContext &  context, PcodeEmit &  emit  ) const

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()

virtual void InjectPayloadGhidra::restoreXml ( const Element *  el )

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.
