## Detailed Description

A checker object that makes it easy to query for whether an analysis or some set covering it is preserved.

Definition at line 266 of file PassManager.h.

## ◆ preserved()

 bool llvm::PreservedAnalyses::PreservedAnalysisChecker::preserved ( )
inline

Returns true if the checker's analysis was not abandoned and either.

• the analysis is explicitly preserved or
• all analyses are preserved.

## ◆ preservedSet()

template<typename AnalysisSetT >
 bool llvm::PreservedAnalyses::PreservedAnalysisChecker::preservedSet ( )
inline

Returns true if the checker's analysis was not abandoned and either.

• AnalysisSetT is explicitly preserved or
• all analyses are preserved.

## ◆ preservedWhenStateless()

 bool llvm::PreservedAnalyses::PreservedAnalysisChecker::preservedWhenStateless ( )
inline

Return true if the checker's analysis was not abandoned, i.e.

it was not explicitly invalidated. Even if the analysis is not explicitly preserved, if the analysis is known stateless, then it is preserved.
