-+@tindex Parameter
-+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 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. */
