Detailed Description

LLVM Value Representation.

This is a very important LLVM class. It is the base class of all values computed by a program that may be used as operands to other values. Value is the super class of other important classes such as Instruction and Function. All Values have a Type. Type is not a subclass of Value. Some values can have a name and they belong to some Module. Setting the name on the Value automatically updates the module's symbol table.

Every value has a "use list" that keeps track of which other Values are using this Value. A Value can also have an arbitrary number of ValueHandle objects that watch it and listen to RAUW and Destroy events. See llvm/IR/ValueHandle.h for details.

Member Enumeration Documentation

anonymous enum

anonymous enum : unsigned

protected

The number of operands in the subclass.

This member is defined by this class, but not used for anything. Subclasses can use it to store their number of operands, if they have any.

This is stored here to save space in User on 64-bit hosts. Since most instances of Value have operands, 32-bit hosts aren't significantly affected.

Note, this should NOT be used directly by any class other than User. User uses this value to find the Use list.

Enumerator
NumUserOperandsBits

Definition at line 107 of file Value.h.

ValueTy

enum llvm::Value::ValueTy

Concrete subclass of this.

An enumeration for keeping track of the concrete subclass of Value that is actually instantiated. Values of this enumeration are kept in the Value classes SubclassID field. They are used for concrete type identification.

~Value()

Value::~Value ( )

protected

Value's destructor should be virtual by design, but that would require that Value and all of its subclasses have a vtable that effectively duplicates the information in the value ID.

As a size optimization, the destructor has been protected, and the caller should manually call deleteValue.

This method computes the number of uses of this Value.

This is a linear time operation. Use hasOneUse, hasNUses, or hasNUsesOrMore to check for specific values.

getPointerAlignment()

Align Value::getPointerAlignment

Returns an alignment of the pointer value.

Returns an alignment which is either specified explicitly, e.g. via align attribute of a function argument, or guaranteed by DataLayout.

getPointerDereferenceableBytes()

uint64_t Value::getPointerDereferenceableBytes	(	const DataLayout &	DL,
		bool &	CanBeNull,
		bool &	CanBeFreed
	)		const

Returns the number of bytes known to be dereferenceable for the pointer value.

If CanBeNull is set by this function the pointer can either be null or be dereferenceable up to the returned number of bytes.

IF CanBeFreed is true, the pointer is known to be dereferenceable at point of definition only. Caller must prove that allocation is not deallocated between point of definition and use.

getValueID()

unsigned llvm::Value::getValueID ( ) const

inline

Return an ID for the concrete type of this object.

This is used to implement the classof checks. This should not be used for any other purpose, as the values may change as LLVM evolves. Also, note that for instructions, the Instruction's opcode is added to InstructionVal. So this means three things:

there is no value with code InstructionVal (no opcode==0).

there are more possible values for the value type than in ValueTy enum.

the InstructionVal enumerator must be the highest valued enumerator in

the ValueTy enum.

hasOneUser()

bool Value::hasOneUser

const

Return true if there is exactly one user of this value.

Note that this is not the same as "has one use". If a value has one use, then there certainly is a single user. But if value has several uses, it is possible that all uses are in a single user, or not.

This check is potentially costly, since it requires traversing, in the worst case, the whole use list of a value.

void llvm::Value::mutateType ( Type *  Ty )

Mutate the type of this Value to be of the specified type.

Note that this is an extremely dangerous operation which can create completely invalid IR very easily. It is strongly recommended that you recreate IR objects with the right types instead of mutating them in place.

stripAndAccumulateConstantOffsets() [2/2]

		APInt &	Offset,
		bool	AllowNonInbounds,
		bool	AllowInvariantGroup = false,
		function_ref< bool(Value &Value, APInt &Offset)>	ExternalAnalysis = nullptr
	)		const

Accumulate the constant offset this value has compared to a base pointer.

Only 'getelementptr' instructions (GEPs) are accumulated but other instructions, e.g., casts, are stripped away as well. The accumulated constant offset is added to Offset and the base pointer is returned.

The APInt Offset has to have a bit-width equal to the IntPtr type for the address space of 'this' pointer value, e.g., use DataLayout::getIndexTypeSizeInBits(Ty).

If AllowNonInbounds is true, offsets in GEPs are stripped and accumulated even if the GEP is not "inbounds".

If AllowInvariantGroup is true then this method also looks through strip.invariant.group and launder.invariant.group intrinsics.

If ExternalAnalysis is provided it will be used to calculate a offset when a operand of GEP is not constant. For example, for a value ExternalAnalysis might try to calculate a lower bound. If ExternalAnalysis is successful, it should return true.

If this is called on a non-pointer value, it returns 'this' and the Offset is not modified.

Note that this function will never return a nullptr. It will also never manipulate the Offset in a way that would not match the difference between the underlying value and the returned one. Thus, if no constant offset was found, the returned value is the underlying one and Offset is unchanged.

SubclassOptionalData

unsigned char llvm::Value::SubclassOptionalData
