+/* * \page gdbtypes GDB Types
+
+ GDB represents all the different kinds of types in programming
+ languages using a common representation defined in gdbtypes.h.
+
+ The main data structure is main_type; it consists of a code (such
+ as #TYPE_CODE_ENUM for enumeration types), a number of
+ generally-useful fields such as the printable name, and finally a
+ field main_type::type_specific that is a union of info specific to
+ particular languages or other special cases (such as calling
+ convention).
+
+ The available type codes are defined in enum #type_code. The enum
+ includes codes both for types that are common across a variety
+ of languages, and for types that are language-specific.
+
+ Most accesses to type fields go through macros such as
+ #TYPE_CODE(thistype) and #TYPE_FN_FIELD_CONST(thisfn, n). These are
+ written such that they can be used as both rvalues and lvalues.
