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

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.

Ty

)

const

Determine if this type could be losslessly bitcast to Ty.

canLosslesslyBitCastTo - Return true if this type could be converted with a lossless BitCast to type 'Ty'. For example, i8* to i32*. BitCasts are valid for types of the same size only where no re-interpretation of the bits is done.

getPrimitiveSizeInBits - 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.

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.

Type* const* llvm::Type::ContainedTys

protected

ContainedTys - A pointer to the array of Types contained by this Type. 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).
