ghidra.program.model.correlate.DisambiguateByParentWithOrder

All Implemented Interfaces:

DisambiguateStrategy

public class DisambiguateByParentWithOrder
extends Object
implements DisambiguateStrategy

Attempt to disambiguate similar n-grams by looking at the parents, AND siblings, of blocks containing the n-grams. This addresses switch constructions in particular, where code for individual cases look very similar but can be distinguished by the ordering of the cases.

Description copied from interface: DisambiguateStrategy

Generate (possibly multiple) hashes that can be used to disambiguate an n-gram and its block from other blocks with similar instructions. Hashes are attached to the block's disambigHash list.

Specified by:

calcHashes in interface DisambiguateStrategy

Parameters:

instHash - the instruction hash

matchSize - the number of instructions to match

store - is the HashStore used to store the disambiguating hashes

Returns:

the list of disambiguating hashes

Throws:

CancelledException
