Member Function Documentation

void* llvm::LibCallAliasAnalysis::getAdjustedAnalysisPointer ( const void * PI ) [inline, override, virtual]

getAdjustedAnalysisPointer - This method is used when a pass implements an analysis interface through multiple inheritance. If needed, it should override this to adjust the this pointer as needed for the specified pass info.

Reimplemented from llvm::Pass.

Definition at line 60 of file LibCallAliasAnalysis.h.

References llvm::AliasAnalysis::ID.

void LibCallAliasAnalysis::getAnalysisUsage ( AnalysisUsage & AU ) const [override, virtual]

getAnalysisUsage - All alias analysis implementations should invoke this directly (using AliasAnalysis::getAnalysisUsage(AU)).

Reimplemented from llvm::AliasAnalysis.

Definition at line 34 of file LibCallAliasAnalysis.cpp.

References llvm::AnalysisUsage::setPreservesAll().

AliasAnalysis::ModRefResult LibCallAliasAnalysis::getModRefInfo	(	ImmutableCallSite	CS,
		const Location &	Loc
	)		`[override, virtual]`

getModRefInfo (for call sites) - Return information about whether a particular call site modifies or reads the specified memory location.

Reimplemented from llvm::AliasAnalysis.

Definition at line 120 of file LibCallAliasAnalysis.cpp.

References F(), llvm::CallSiteBase< FunTy, ValTy, UserTy, InstrTy, CallTy, InvokeTy, IterTy >::getCalledFunction(), llvm::LibCallInfo::getFunctionInfo(), LCI, llvm::AliasAnalysis::ModRef, and llvm::AliasAnalysis::NoModRef.

ModRefResult llvm::LibCallAliasAnalysis::getModRefInfo	(	ImmutableCallSite	CS1,
		ImmutableCallSite	CS2
	)		`[inline, override, virtual]`

getModRefInfo - Return information about whether two call sites may refer to the same set of memory locations. See http://llvm.org/docs/AliasAnalysis.html#ModRefInfo for details.

Reimplemented from llvm::AliasAnalysis.

Definition at line 43 of file LibCallAliasAnalysis.h.
