Member Function Documentation

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.

Definition at line 239 of file Analysis.h.

References llvm::SmallPtrSetImpl< PtrType >::count().

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.

Definition at line 252 of file Analysis.h.

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.
