Detailed Description

The instances of the Type class are immutable: once they are created, they are never changed.

Also note that only one instance of a particular type is ever created. Thus seeing if two types are equal is a matter of doing a trivial pointer comparison. To enforce that no two equal instances are created, Type instances can only be created via static factory methods in class Type and in derived classes. Once allocated, Types are never free'd.

Member Enumeration Documentation

◆ TypeID

enum llvm::Type::TypeID

Definitions of all of the base types for the Type system.

Based on this value, you can cast to a class defined in DerivedTypes.h. Note: If you add an element to this, you need to add an element to the Type::getPrimitiveType function, or else things will break! Also update LLVMTypeKind and LLVMGetTypeKind () in the C binding.

◆ getPrimitiveSizeInBits()

TypeSize llvm::Type::getPrimitiveSizeInBits ( ) const

Return the basic size of this type if it is a primitive type.

These are fixed by LLVM and are not target-dependent. This will return zero if the type does not have a size or is not a primitive type.

If this is a scalable vector type, the scalable property will be set and the runtime size will be a positive integer multiple of the base size.

Note that this may not reflect the size of memory allocated for an instance of the type or the number of bytes that are written when an instance of the type is stored to memory. The DataLayout class provides additional query functions to provide this information.

◆ ContainedTys

Type* const* llvm::Type::ContainedTys = nullptr

protected

For example, this includes the arguments of a function type, the elements of a structure, the pointee of a pointer, the element type of an array, etc. This pointer may be 0 for types that don't contain other types (Integer, Double, Float).
