Constructor & Destructor Documentation

◆ DependenceInfo()

polly::DependenceInfo::DependenceInfo ( )

inline

Construct a new DependenceInfo pass.

Definition at line 240 of file DependenceInfo.h.

Member Function Documentation

◆ abandonDependences()

void DependenceInfo::abandonDependences ( )

Invalidate the dependence information and recompute it when needed again.

May be required when the underlaying Scop was changed in a way that would add new dependencies (e.g. between new statement instances insierted into the SCoP) or intentionally breaks existing ones. It is not required when updating the schedule that conforms the existing dependencies.

Definition at line 899 of file DependenceInfo.cpp.

◆ getAnalysisUsage()

void DependenceInfo::getAnalysisUsage ( AnalysisUsage & AU ) const

override

Register all analyses and transformation required.

Definition at line 923 of file DependenceInfo.cpp.

◆ getDependences()

const Dependences & DependenceInfo::getDependences ( Dependences::AnalysisLevel Level )

Return the dependence information for the current SCoP.

Parameters

Level The granularity of dependence analysis result.

Returns: The dependence analysis result

◆ printScop()

void polly::DependenceInfo::printScop	(	raw_ostream &	OS,
		Scop &	S
	)		const

overridevirtual

Print the dependences for the given SCoP to OS.
