++Non-@code{NULL} value indicates it is owned by an objfile (specifically by its

++or reloaded. For such types with an associated objfile no reference counting

++User convenience variables, et cetera, have associated types. Normally these
++types live in the associated objfile. However, when the objfile is unloaded,
++those types are deep copied to global memory, so that the values of the user
++variables and history items are not lost. During the copy they will get their
++@code{TYPE_OBJFILE} set to @code{NULL} and become so-called @dfn{reclaimable}
++types.
++
++Types with null @code{TYPE_OBJFILE} can be either permanent types
++(@pxref{Builtin Types}) or reclaimable types which will be deallocated at the
++first idle @value{GDBN} moment if the last object referencing them is removed.
++Permanent types are allocated by the function @code{alloc_type} (and its
++derivations like @code{init_type}) specifying objfile as @code{NULL}. The
++reclaimable types are created the same way but moreover they need to have
++@code{type_init_group} called to start their tracking as being possibly
++deallocatable.
++
++@findex free_all_types
++When @value{GDBN} gets idle it always calls the @code{free_all_types} function
++which deallocates any unused types. All types currently not owned by an
++objfile must be marked as used on each @code{free_all_types} call as they would
++get deallocated as unused otherwise.
++
++@code{free_all_types} automatically checks for any cross-type references such
++as through @code{TYPE_TARGET_TYPE}, @code{TYPE_POINTER_TYPE} etc.@: and
++prevents early deallocation for any such existing references. Reclaimable
++types may reference any other reclaimable types or even permanent types. But
++permanent types must not reference reclaimable types (nor an objfile associated
++type).

-- Now, many of these operations are specific to a particular
-- host/target character set pair. If GDB supports N character sets,
-- there are N^2 possible pairs. This means that, the larger GDB's
-- repertoire of character sets gets, the more expensive it gets to add
-- new character sets.
--
-- To make sure that GDB can do the right thing for every possible
-- pairing of host and target character set, while still allowing
-- GDB's repertoire to scale, we use a two-tiered approach:
--
-- - We maintain a global table of "translations" --- groups of
-- functions specific to a particular pair of character sets.
--
-- - However, a translation can be incomplete: some functions can be
-- omitted. Where there is not a translation to specify exactly
-- what function to use, we provide reasonable defaults. The
-- default behaviors try to use the "iconv" library functions, which
-- support a wide range of character sets. However, even if iconv
-- is not available, there are fallbacks to support trivial
-- translations: when the host and target character sets are the

-+@subsubsection Auto-loading
-+
-+When a new object file (@pxref{Objfiles In Python}) is read (for
-+example, due to the @code{file} command, or because the inferior has
-+loaded a shared library), @value{GDBN} will look for a file named by
-+adding @samp{-gdb.py} to the object file's real name (the name formed
-+after following all symlinks and resolving @code{.} and @code{..}
-+components). If this file exists and is readable, @value{GDBN} will
-+evaluate it as a Python script.
-+
-+If this file does not exist, and if the parameter
-+@code{debug-file-directory} is set, then @value{GDBN} will append the
-+object file's real name to the value of this parameter, and try again.
-+
-+Finally, if this file does not exist, then @value{GDBN} will look in
-+subdirectory of @code{gdb_datadir} (whose value is available from
-+@code{maint show gdb_datadir}). Specifically, @value{GDBN} will take
-+the value of @code{gdb_datadir}, append @samp{python/auto-load}, and
-+then append the object file's real name.
-+
-+Also, if a separate debug file is used, @value{GDBN} will look for the
-+@samp{-gdb.py} file both in the directory associated with the
-+application and the directory associated with the separate debug file.
-+
-+When reading a @samp{-gdb.py} file, @value{GDBN} sets the ``current
-+objfile''. This is available via the @code{gdb.current_objfile}
-+function. This can be useful for registering objfile-specific
-+pretty-printers.
-+
-+This feature is useful for supplying application-specific debugging
-+commands and scripts. It can be disabled using @code{maint set python
-+auto-load}.
-+
-+@value{GDBN} does not track which files it has already auto-loaded.
-+So, your @samp{-gdb.py} file should take care to ensure that it may be
-+evaluated multiple times without error.

-+@node Pretty Printing
-+@subsubsection Pretty Printing
-+
-+@value{GDBN} provides a mechanism to allow pretty-printing of values
-+using Python code. This mechanism works for both MI and the CLI.
-+
-+A pretty-printer is an object that implements a specific interface.
-+There is no predefined base class for pretty-printers.
-+
-+@defop Operation {pretty printer} __init__ (self, val)
-+When printing a value, @value{GDBN} constructs an instance of the
-+pretty-printer. @var{val} is the value to be printed, an instance of
-+@code{gdb.Value}.
-+@end defop
-+
-+@defop Operation {pretty printer} children (self)
-+When printing a value, @value{GDBN} will call this method to compute
-+the children of the value passed to the object's constructor.
-+
-+This method must return an object conforming to the Python iterator
-+protocol. Each element returned by the iterator must be a tuple
-+holding two elements. The first element is the ``name'' of the child;
-+the second element is the child's value. The value can be any Python
-+object which is convertible to a @value{GDBN} value.
-+
-+This method is optional. If it does not exist, @value{GDBN} will act
-+as though the value has no children.
-+@end defop
-+
-+@defop Operation {pretty printer} display_hint (self)
-+This method must return a string. The CLI may use this to change the
-+formatting of children of a value. The result will also be supplied
-+to an MI consumer as a @samp{displayhint} attribute of the variable
-+being printed.
-+
-+Some display hints are predefined by @value{GDBN}:
-+
-+@table @samp
-+@item array
-+Indicate that the object being printed is ``array-like''. The CLI
-+uses this to respect parameters such as @code{set print elements} and
-+@code{set print array}.
-+
-+@item map
-+Indicate that the object being printed is ``map-like'', and that the
-+children of this value can be assumed to alternate between keys and
-+values.
-+
-+@item string
-+Indicate that the object being printed is ``string-like''. If the
-+printer's @code{to_string} method returns a Python string of some
-+kind, then @value{GDBN} will call its internal language-specific
-+string-printing function to format the string. For the CLI this means
-+adding quotation marks, possibly escaping some characters, respecting
-+@code{set print elements}, and the like.
-+@end table
-+@end defop
-+
-+@defop Operation {pretty printer} to_string (self)
-+@value{GDBN} will call this method to display the string
-+representation of the value passed to the object's constructor.
-+
-+When printing from the CLI, if the @code{to_string} method exists,
-+then @value{GDBN} will prepend its result to the values returned by
-+@code{children}.
-+
-+If this method returns a string, it is printed verbatim. Otherwise,
-+the result is converted to a @code{gdb.Value}, following the usual
-+algorithm. Then @value{GDBN} prints this value; this may possibly
-+result in a call to another pretty-printer. If the result is not
-+convertible to @code{gdb.Value}, an exception is raised.
-+@end defop
-+
-+@subsubsection Selecting Pretty-Printers
-+
-+The Python list @code{gdb.pretty_printers} contains an array of
-+functions that have been registered via addition as a pretty-printer.
-+Each function will be called with a @code{gdb.Value} to be
-+pretty-printed. Each @code{gdb.Objfile} also contains a
-+@code{pretty_printers} attribute. A function on one of these lists
-+takes a single @code{gdb.Value} argument and returns a pretty-printer
-+object conforming to the interface definition above. If this function
-+cannot create a pretty-printer for the value, it should return
-+@code{None}.
-+
-+@value{GDBN} first checks the @code{pretty_printers} attribute of each
-+@code{gdb.Objfile} and iteratively calls each function in the list for
-+that @code{gdb.Objfile} until it receives a pretty-printer object.
-+After these @code{gdb.Objfile} have been exhausted, it tries the
-+global @code{gdb.pretty-printers} list, again calling each function
-+until an object is returned.
-+
-+The order in which the objfiles are searched is not specified.
-+Functions are always invoked from the head of the
-+@code{gdb.pretty-printers} list, and iterated over sequentially until
-+the end of the list, or a printer object is returned.
-+
-+Here is an example showing how a @code{std::string} printer might be
-+written:
+ /* For Ada types, make sure that the gnat-specific data is always
+ initialized (if not already set). There are a few types where
+ we should not be doing so, because the type-specific area is

-+You can implement new @value{GDBN} parameters using Python. A new
-+parameter is implemented as an instance of the @code{gdb.Parameter}
-+class. Parameters are exposed to the user via the @code{set} and
-+@code{show} commands.
-+
-+@defmethod Parameter __init__ name @var{command-class} @var{parameter-class} @r{[}@var{enum-sequence}@r{]}
-+The object initializer for @code{Parameter} registers the new
-+parameter with @value{GDBN}. This initializer is normally invoked
-+from the subclass' own @code{__init__} method.
-+
-+@var{name} is the name of the new parameter. If @var{name} consists
-+of multiple words, then the initial words are looked for as prefix
-+commands. In this case, if one of the prefix commands does not exist,
-+an exception is raised.
-+
-+@var{command-class} should be one of the @samp{COMMAND_} constants
-+(@pxref{Commands In Python}). This argument tells @value{GDBN} how to
-+categorize the new parameter in the help system.
-+
-+@var{parameter-class} should be one of the @samp{PARAM_} constants
-+defined below. This argument tells @value{GDBN} the type of the new
-+parameter; this information is used for input validation and
-+completion.
-+
-+If @var{parameter-class} is @code{PARAM_ENUM}, then
-+@var{enum-sequence} must be a sequence of strings. These strings
-+represent the possible values for the parameter.
-+
-+If @var{parameter-class} is not @code{PARAM_ENUM}, then the presence
-+of a fourth argument will cause an exception to be thrown.
-+
-+The help text for the new parameter is taken from the Python

-+
-+@findex PARAM_UINTEGER

-+You can implement new convenience functions (@pxref{Convenience Vars})
-+in Python. A convenience function is an instance of a subclass of the
-+class @code{gdb.Function}.
-+
-+@defmethod Function __init__ name
-+The initializer for @code{Function} registers the new function with
-+@value{GDBN}. The argument @var{name} is the name of the function,
-+a string. The function will be visible to the user as a convenience
-+variable of type @code{internal function}, whose name is the same as
-+the given @var{name}.
-+
-+The documentation for the new function is taken from the documentation
-+string for the new class.
-+@end defmethod
-+
-+@defmethod Function invoke @var{*args}
-+When a convenience function is evaluated, its arguments are converted
-+to instances of @code{gdb.Value}, and then the function's
-+@code{invoke} method is called. Note that @value{GDBN} does not
-+predetermine the arity of convenience functions. Instead, all
-+available arguments are passed to @code{invoke}, following the
-+standard Python calling convention. In particular, a convenience
-+function can have default values for parameters without ill effect.

-+The return value of this method is used as its value in the enclosing
-+expression. If an ordinary Python value is returned, it is converted

++/* The mapped index file format is designed to be directly mmap()able
++ on any architecture. In most cases, a datum is represented using a
++ little-endian 32-bit integer value, called an offset_type. Big
++ endian machines must byte-swap the values before using them.
++ Exceptions to this rule are noted. The data is laid out such that
++ alignment is always respected.
++
++ A mapped index consists of several sections.
++
++ 1. The file header. This is a sequence of values, of offset_type
++ unless otherwise noted:
++ [0] The version number. Currently 1.
++ [1] The offset, from the start of the file, of the CU list.
++ [2] The offset, from the start of the file, of the address section.
++ [3] The offset, from the start of the file, of the symbol table.
++ [4] The offset, from the start of the file, of the constant pool.
++
++ 2. The CU list. This is a sequence of pairs of 64-bit
++ little-endian values. The first element in each pair is the offset
++ of a CU in the .debug_info section. The second element in each
++ pair is the length of that CU. References to a CU elsewhere in the
++ map are done using a CU index, which is just the 0-based index into
++ this table.
++
++ 3. The address section. The address section consists of a sequence
++ of address entries. Each address entry has three elements.
++ [0] The low address. This is a 64-bit little-endian value.
++ [1] The high address. This is a 64-bit little-endian value.
++ [2] The CU index. This is an offset_type value.
++
++ 4. The symbol table. This is a hash table. The size of the hash
++ table is always a power of 2. The initial hash and the step are
++ currently defined by the `find_slot' function.
++
++ Each slot in the hash table consists of a pair of offset_type
++ values. The first value is the offset of the symbol's name in the
++ constant pool. The second value is the offset of the CU vector in
++ the constant pool.
++
++ If both values are 0, then this slot in the hash table is empty.
++ This is ok because while 0 is a valid constant pool index, it
++ cannot be a valid index for both a string and a CU vector.
++
++ A string in the constant pool is stored as a \0-terminated string,
++ as you'd expect.
++
++ A CU vector in the constant pool is a sequence of offset_type
++ values. The first value is the number of CU indices in the vector.
++ Each subsequent value is the index of a CU in the CU list. This
++ element in the hash table is used to indicate which CUs define the
++ symbol.
++
++ 5. The constant pool. This is simply a bunch of bytes. It is
++ organized so that alignment is correct: CU vectors are stored
++ first, followed by strings. */
