Detailed Description

Determine active parameters to sub-functions.

This is the final stage of the parameter recovery process, when a prototype for a sub-function is not explicitly known. Putative input Varnode parameters are collected by the Heritage process. This class determines which of these Varnodes are being used as parameters. This needs to be called after ActionHeritage and after ActionDirectWrite but before any simplification or copy propagation has been performed.

Member Function Documentation

◆ apply()

int4 ghidra::ActionActiveParam::apply ( Funcdata data)
virtual

◆ clone()

virtual Action* ghidra::ActionActiveParam::clone ( const ActionGroupList grouplist) const
inlinevirtual

Clone the Action.

If this Action is a member of one of the groups in the grouplist, this returns a clone of the Action, otherwise NULL is returned.

Parameters
grouplistis the list of groups being cloned
Returns
the cloned Action or NULL

Implements ghidra::Action.
