-// This file defines the AST type info database. Each type node is
-// enumerated by providing its name (e.g., "Builtin" or "Enum") and
-// base class (e.g., "Type" or "TagType"). Depending on where in the
-// abstract syntax tree the type will show up, the enumeration uses
-// one of five different macros:
-//
-// TYPE(Class, Base) - A type that can show up anywhere in the AST,
-// and might be dependent, canonical, or non-canonical. All clients
-// will need to understand these types.
-//
-// ABSTRACT_TYPE(Class, Base) - An abstract class that shows up in
-// the type hierarchy but has no concrete instances.
-//
-// NON_CANONICAL_TYPE(Class, Base) - A type that can show up
-// anywhere in the AST but will never be a part of a canonical
-// type. Clients that only need to deal with canonical types
-// (ignoring, e.g., typedefs and other type aliases used for
-// pretty-printing) can ignore these types.
-//
-// DEPENDENT_TYPE(Class, Base) - A type that will only show up
-// within a C++ template that has not been instantiated, e.g., a
-// type that is always dependent. Clients that do not need to deal
-// with uninstantiated C++ templates can ignore these types.
-//
-// NON_CANONICAL_UNLESS_DEPENDENT_TYPE(Class, Base) - A type that
-// is non-canonical unless it is dependent. Defaults to TYPE because
-// it is neither reliably dependent nor reliably non-canonical.
-//
-// There is a sixth macro, independent of the others. Most clients
-// will not need to use it.
-//
-// LEAF_TYPE(Class) - A type that never has inner types. Clients
-// which can operate on such types more efficiently may wish to do so.

+This attribute can be used on a function or variable to specify its symbol name.
+
+On some targets, all C symbols are prefixed by default with a single character, typically ``_``. This was done historically to distinguish them from symbols used by other languages. (This prefix is also added to the standard Itanium C++ ABI prefix on "mangled" symbol names, so that e.g. on such targets the true symbol name for a C++ variable declared as ``int cppvar;`` would be ``__Z6cppvar``; note the two underscores.) This prefix is *not* added to the symbol names specified by the ``asm`` attribute; programmers wishing to match a C symbol name must compensate for this.
+
+For example, consider the following C code:
+
+.. code-block:: c
+
+ int var1 asm("altvar") = 1; // "altvar" in symbol table.
+ int var2 = 1; // "_var2" in symbol table.
+
+ void func1(void) asm("altfunc");
+ void func1(void) {} // "altfunc" in symbol table.
+ void func2(void) {} // "_func2" in symbol table.
+
+Clang's implementation of this attribute is compatible with GCC's, `documented here <https://gcc.gnu.org/onlinedocs/gcc/Asm-Labels.html>`_.
+
+While it is possible to use this attribute to name a special symbol used internally by the compiler, such as an LLVM intrinsic, this is neither recommended nor supported and may cause the compiler to crash or miscompile. Users who wish to gain access to intrinsic behavior are strongly encouraged to request new builtin functions.

+/// based on how a type is spelled and which therefore are not consistent
+/// with immediately stipping away type sugar. More critically, attributes on
+/// typedefs can have semantic impacts in ways that are only reflected in our
