Detailed Description

This class represents the main alias analysis interface in MLIR.

It functions as an aggregate of various different alias analysis implementations. This aggregation allows for utilizing the strengths of different alias analysis implementations that either target or have access to different aliasing information. This is especially important for MLIR given the scope of different types of memory models and aliasing behaviors. For users of this analysis that want to perform aliasing queries, see the Alias Queries section below for the available methods. For users of this analysis that want to add a new alias analysis implementation to the aggregate, see the Alias Implementations section below.

Member Function Documentation

◆ addAnalysisImplementation()

template<typename AnalysisT >
void mlir::AliasAnalysis::addAnalysisImplementation ( AnalysisT &&  analysis)
inline

Add a new alias analysis implementation AnalysisT to this analysis aggregate.

This allows for users to access this implementation when performing alias queries. Implementations added here must provide the following:

◆ alias()

AliasResult AliasAnalysis::alias ( Value  lhs,
Value  rhs 
)

Given two values, return their aliasing behavior.

◆ getModRef()

ModRefResult AliasAnalysis::getModRef ( Operation op,
Value  location 
)

Return the modify-reference behavior of op on location.
