Classes
struct	llvm::ObjectSizeOpts
	Various options to control the behavior of getObjectSize. More...
class	llvm::ObjectSizeOffsetVisitor
	Evaluate the size and offset of an object pointed to by a Value* statically. More...
class	llvm::ObjectSizeOffsetEvaluator
	Evaluate the size and offset of an object pointed to by a Value*. More...

Namespaces

using	llvm::SizeOffsetEvalType = std::pair< Value *, Value * >

Functions
bool	llvm::isAllocationFn (const Value *V, const TargetLibraryInfo *TLI, bool LookThroughBitCast=false)
	Tests if a value is a call or invoke to a library function that allocates or reallocates memory (either malloc, calloc, realloc, or strdup like). More...
bool	llvm::isNoAliasFn (const Value *V, const TargetLibraryInfo *TLI, bool LookThroughBitCast=false)
	Tests if a value is a call or invoke to a function that returns a NoAlias pointer (including malloc/calloc/realloc/strdup-like functions). More...
bool	llvm::isMallocLikeFn (const Value *V, const TargetLibraryInfo *TLI, bool LookThroughBitCast=false)
	Tests if a value is a call or invoke to a library function that allocates uninitialized memory (such as malloc). More...
bool	llvm::isCallocLikeFn (const Value *V, const TargetLibraryInfo *TLI, bool LookThroughBitCast=false)
	Tests if a value is a call or invoke to a library function that allocates zero-filled memory (such as calloc). More...
bool	llvm::isMallocOrCallocLikeFn (const Value *V, const TargetLibraryInfo *TLI, bool LookThroughBitCast=false)
	Tests if a value is a call or invoke to a library function that allocates memory similar to malloc or calloc. More...
bool	llvm::isAllocLikeFn (const Value *V, const TargetLibraryInfo *TLI, bool LookThroughBitCast=false)
	Tests if a value is a call or invoke to a library function that allocates memory (either malloc, calloc, or strdup like). More...
const CallInst *	llvm::extractMallocCall (const Value *I, const TargetLibraryInfo *TLI)
	extractMallocCall - Returns the corresponding CallInst if the instruction is a malloc call. More...
CallInst *	llvm::extractMallocCall (Value *I, const TargetLibraryInfo *TLI)
PointerType *	llvm::getMallocType (const CallInst *CI, const TargetLibraryInfo *TLI)
	getMallocType - Returns the PointerType resulting from the malloc call. More...
Type *	llvm::getMallocAllocatedType (const CallInst *CI, const TargetLibraryInfo *TLI)
	getMallocAllocatedType - Returns the Type allocated by malloc call. More...
Value *	llvm::getMallocArraySize (CallInst *CI, const DataLayout &DL, const TargetLibraryInfo *TLI, bool LookThroughSExt=false)
	getMallocArraySize - Returns the array size of a malloc call. More...
const CallInst *	llvm::extractCallocCall (const Value *I, const TargetLibraryInfo *TLI)
	extractCallocCall - Returns the corresponding CallInst if the instruction is a calloc call. More...
CallInst *	llvm::extractCallocCall (Value *I, const TargetLibraryInfo *TLI)
const CallInst *	llvm::isFreeCall (const Value *I, const TargetLibraryInfo *TLI)
	isFreeCall - Returns non-null if the value is a call to the builtin free() More...
CallInst *	llvm::isFreeCall (Value *I, const TargetLibraryInfo *TLI)
bool	llvm::getObjectSize (const Value *Ptr, uint64_t &Size, const DataLayout &DL, const TargetLibraryInfo *TLI, ObjectSizeOpts Opts={})
	Compute the size of the object pointed by Ptr. More...
ConstantInt *	llvm::lowerObjectSizeCall (IntrinsicInst *ObjectSize, const DataLayout &DL, const TargetLibraryInfo *TLI, bool MustSucceed)
	Try to turn a call to @llvm.objectsize into an integer value of the given Type. More...
