class BTFTagAttributedType

Declaration

class BTFTagAttributedType : public Type, public Node { /* full declaration omitted */ };

Description

The base class of the type hierarchy. A central concept with types is that each type always has a canonical type. A canonical type is the type with any typedef names stripped out of it or the types it references. For example, consider: typedef int foo; typedef foo* bar; 'int *' 'foo *' 'bar' There will be a Type object created for 'int'. Since int is canonical, its CanonicalType pointer points to itself. There is also a Type for 'foo' (a TypedefType). Its CanonicalType pointer points to the 'int' Type. Next there is a PointerType that represents 'int*', which, like 'int', is canonical. Finally, there is a PointerType type for 'foo*' whose canonical type is 'int*', and there is a TypedefType for 'bar', whose canonical type is also 'int*'. Non-canonical types are useful for emitting diagnostics, without losing information about typedefs being used. Canonical types are useful for type comparisons (they allow by-pointer equality tests) and useful for reasoning about whether something has a particular form (e.g. is a function type), because they implicitly, recursively, strip all typedefs out of a type. Types, once created, are immutable.
