Classes
struct	llvm::DevirtCallSite
	A call site that could be devirtualized. More...

Namespaces
namespace	llvm
	This is an optimization pass for GlobalISel generic memory operations.

Enumerations
enum	llvm::CfiFunctionLinkage { llvm::CFL_Definition = 0 , llvm::CFL_Declaration = 1 , llvm::CFL_WeakDeclaration = 2 }
	The type of CFI jumptable needed for a function. More...

Functions
void	llvm::findDevirtualizableCallsForTypeTest (SmallVectorImpl< DevirtCallSite > &DevirtCalls, SmallVectorImpl< CallInst * > &Assumes, const CallInst *CI, DominatorTree &DT)
	Given a call to the intrinsic @llvm.type.test, find all devirtualizable call sites based on the call and return them in DevirtCalls.
void	llvm::findDevirtualizableCallsForTypeCheckedLoad (SmallVectorImpl< DevirtCallSite > &DevirtCalls, SmallVectorImpl< Instruction * > &LoadedPtrs, SmallVectorImpl< Instruction * > &Preds, bool &HasNonCallUses, const CallInst *CI, DominatorTree &DT)
	Given a call to the intrinsic @llvm.type.checked.load, find all devirtualizable call sites based on the call and return them in DevirtCalls.
Constant *	llvm::getPointerAtOffset (Constant *I, uint64_t Offset, Module &M, Constant *TopLevelGlobal=nullptr)
	Processes a Constant recursively looking into elements of arrays, structs and expressions to find a trivial pointer element that is located at the given offset (relative to the beginning of the whole outer Constant).
void	llvm::replaceRelativePointerUsersWithZero (Function *F)
	Finds the same "relative pointer" pattern as described above, where the target is F, and replaces the entire pattern with a constant zero.
