@chapter @sc{gnu} C++ Conformance to @sc{ansi} C++
|
||||
|
||||
These changes in the @sc{gnu} C++ compiler were made to comply more
|
||||
closely with the @sc{ansi} base document, @cite{The Annotated C++
|
||||
Reference Manual} (the @sc{arm}). Further reducing the divergences from
|
||||
@sc{ansi} C++ is a continued goal of the @sc{gnu} C++ Renovation
|
||||
Project.
|
||||
|
||||
@b{Section 3.4}, @i{Start and Termination}. It is now invalid to take
|
||||
the address of the function @samp{main()}.
|
||||
|
||||
@b{Section 4.8}, @i{Pointers to Members}. The compiler produces
|
||||
an error for trying to convert between a pointer to a member and the type
|
||||
@samp{void *}.
|
||||
|
||||
@b{Section 5.2.5}, @i{Increment and Decrement}. It is an error to use
|
||||
the increment and decrement operators on an enumerated type.
|
||||
|
||||
@b{Section 5.3.2}, @i{Sizeof}. Doing @code{sizeof} on a function is now
|
||||
an error.
|
||||
|
||||
@b{Section 5.3.4}, @i{Delete}. The syntax of a @i{cast-expression} is
|
||||
now more strictly controlled.
|
||||
|
||||
@b{Section 7.1.1}, @i{Storage Class Specifiers}. Using the
|
||||
@code{static} and @code{extern} specifiers can now only be applied to
|
||||
names of objects, functions, and anonymous unions.
|
||||
|
||||
@b{Section 7.1.1}, @i{Storage Class Specifiers}. The compiler no longer complains
|
||||
about taking the address of a variable which has been declared to have @code{register}
|
||||
storage.
|
||||
|
||||
@b{Section 7.1.2}, @i{Function Specifiers}. The compiler produces an
|
||||
error when the @code{inline} or @code{virtual} specifiers are
|
||||
used on anything other than a function.
|
||||
|
||||
@b{Section 8.3}, @i{Function Definitions}. It is now an error to shadow
|
||||
a parameter name with a local variable; in the past, the compiler only
|
||||
gave a warning in such a situation.
|
||||
|
||||
@b{Section 8.4.1}, @i{Aggregates}. The rules concerning declaration of
|
||||
an aggregate are now all checked in the @sc{gnu} C++ compiler; they
|
||||
include having no private or protected members and no base classes.
|
||||
|
||||
@b{Section 8.4.3}, @i{References}. Declaring an array of references is
|
||||
now forbidden. Initializing a reference with an initializer list is
|
||||
also considered an error.
|
||||
|
||||
@b{Section 9.5}, @i{Unions}. Global anonymous unions must be declared
|
||||
@code{static}.
|
||||
|
||||
@b{Section 11.4}, @i{Friends}. Declaring a member to be a friend of a
|
||||
type that has not yet been defined is an error.
|
||||
|
||||
@b{Section 12.1}, @i{Constructors}. The compiler generates a
|
||||
default copy constructor for a class if no constructor has been declared.
|
||||
|
||||
@ignore
|
||||
@b{Section 12.4}, @i{Destructors}. In accordance with the @sc{ansi} C++
|
||||
draft standard working paper, a pure virtual destructor must now be
|
||||
defined.
|
||||
@end ignore
|
||||
|
||||
@b{Section 12.6.2}, @i{Special Member Functions}. When using a
|
||||
@i{mem-initializer} list, the compiler will now initialize class members
|
||||
in declaration order, not in the order in which you specify them.
|
||||
Also, the compiler enforces the rule that non-static @code{const}
|
||||
and reference members must be initialized with a @i{mem-initializer}
|
||||
list when their class does not have a constructor.
|
||||
|
||||
@b{Section 12.8}, @i{Copying Class Objects}. The compiler generates
|
||||
default copy constructors correctly, and supplies default assignment
|
||||
operators compatible with user-defined ones.
|
||||
|
||||
@b{Section 13.4}, @i{Overloaded Operators}. An overloaded operator may
|
||||
no longer have default arguments.
|
||||
|
||||
@b{Section 13.4.4}, @i{Function Call}. An overloaded @samp{operator ()}
|
||||
must be a non-static member function.
|
||||
|
||||
@b{Section 13.4.5}, @i{Subscripting}. An overloaded @samp{operator []}
|
||||
must be a non-static member function.
|
||||
|
||||
@b{Section 13.4.6}, @i{Class Member Access}. An overloaded @samp{operator ->}
|
||||
must be a non-static member function.
|
||||
|
||||
@b{Section 13.4.7}, @i{Increment and Decrement}. The compiler will now
|
||||
make sure a postfix @samp{@w{operator ++}} or @samp{@w{operator --}} has an
|
||||
@code{int} as its second argument.

@chapter Name Encoding in @sc{gnu} C++
|
||||
|
||||
@c FIXME!! rewrite name encoding section
|
||||
@c ...to give complete rules rather than diffs from ARM.
|
||||
@c To avoid plagiarism, invent some different way of structuring the
|
||||
@c description of the rules than what ARM uses.
|
||||
|
||||
@cindex mangling
|
||||
@cindex name encoding
|
||||
@cindex encoding information in names
|
||||
In order to support its strong typing rules and the ability to provide
|
||||
function overloading, the C++ programming language @dfn{encodes}
|
||||
information about functions and objects, so that conflicts across object
|
||||
files can be detected during linking. @footnote{This encoding is also
|
||||
sometimes called, whimsically enough, @dfn{mangling}; the corresponding
|
||||
decoding is sometimes called @dfn{demangling}.} These rules tend to be
|
||||
unique to each individual implementation of C++.
|
||||
|
||||
The scheme detailed in the commentary for 7.2.1 of @cite{The Annotated
|
||||
Reference Manual} offers a description of a possible implementation
|
||||
which happens to closely resemble the @code{cfront} compiler. The
|
||||
design used in @sc{gnu} C++ differs from this model in a number of ways:
|
||||
|
||||
@itemize @bullet
|
||||
@item
|
||||
In addition to the basic types @code{void}, @code{char}, @code{short},
|
||||
@code{int}, @code{long}, @code{float}, @code{double}, and @code{long
|
||||
double}, @sc{gnu} C++ supports two additional types: @code{wchar_t}, the wide
|
||||
character type, and @code{long long} (if the host supports it). The
|
||||
encodings for these are @samp{w} and @samp{x} respectively.
|
||||
|
||||
@item
|
||||
According to the @sc{arm}, qualified names (e.g., @samp{foo::bar::baz}) are
|
||||
encoded with a leading @samp{Q}. Followed by the number of
|
||||
qualifications (in this case, three) and the respective names, this
|
||||
might be encoded as @samp{Q33foo3bar3baz}. @sc{gnu} C++ adds a leading
|
||||
underscore to the list, producing @samp{_Q33foo3bar3baz}.
|
||||
|
||||
@item
|
||||
The operator @samp{*=} is encoded as @samp{__aml}, not @samp{__amu}, to
|
||||
match the normal @samp{*} operator, which is encoded as @samp{__ml}.
|
||||
|
||||
@c XXX left out ->(), __wr
|
||||
@item
|
||||
In addition to the normal operators, @sc{gnu} C++ also offers the minimum and
|
||||
maximum operators @samp{>?} and @samp{<?}, encoded as @samp{__mx} and
|
||||
@samp{__mn}, and the conditional operator @samp{?:}, encoded as @samp{__cn}.
|
||||
|
||||
@cindex destructors, encoding of
|
||||
@cindex constructors, encoding of
|
||||
@item
|
||||
Constructors are encoded as simply @samp{__@var{name}}, where @var{name}
|
||||
is the encoded name (e.g., @code{3foo} for the @code{foo} class
|
||||
constructor). Destructors are encoded as two leading underscores
|
||||
separated by either a period or a dollar sign, depending on the
|
||||
capabilities of the local host, followed by the encoded name. For
|
||||
example, the destructor @samp{foo::~foo} is encoded as @samp{_$_3foo}.
|
||||
|
||||
@item
|
||||
Virtual tables are encoded with a prefix of @samp{_vt}, rather than
|
||||
@samp{__vtbl}. The names of their classes are separated by dollar signs
|
||||
(or periods), and not encoded as normal: the virtual table for
|
||||
@code{foo} is @samp{__vt$foo}, and the table for @code{foo::bar} is
|
||||
named @samp{__vt$foo$bar}.
|
||||
|
||||
@item
|
||||
Static members are encoded as a leading underscore, followed by the
|
||||
encoded name of the class in which they appear, a separating dollar sign
|
||||
or period, and finally the unencoded name of the variable. For example,
|
||||
if the class @code{foo} contains a static member @samp{bar}, its
|
||||
encoding would be @samp{_3foo$bar}.
|
||||
|
||||
@item
|
||||
@sc{gnu} C++ is not as aggressive as other compilers when it comes to always
|
||||
generating @samp{Fv} for functions with no arguments. In particular,
|
||||
the compiler does not add the sequence to conversion operators. The
|
||||
function @samp{foo::bar()} is encoded as @samp{bar__3foo}, not
|
||||
@samp{bar__3fooFv}.
|
||||
|
||||
@item
|
||||
The argument list for methods is not prefixed by a leading @samp{F}; it
|
||||
is considered implied.
|
||||
|
||||
@item
|
||||
@sc{gnu} C++ approaches the task of saving space in encodings
|
||||
differently from that noted in the @sc{arm}. It does use the
|
||||
@samp{T@var{n}} and @samp{N@var{x}@var{y}} codes to signify copying the
|
||||
@var{n}th argument's type, and making the next @var{x} arguments be the
|
||||
type of the @var{y}th argument, respectively. However, the values for
|
||||
@var{n} and @var{y} begin at zero with @sc{gnu} C++, whereas the
|
||||
@sc{arm} describes them as starting at one. For the function @samp{foo
|
||||
(bartype, bartype)}, @sc{gnu} C++ uses @samp{foo__7bartypeT0}, while
|
||||
compilers following the @sc{arm} example generate @samp{foo__7bartypeT1}.
|
||||
|
||||
@c Note it loses on `foo (int, int, int, int, int)'.
|
||||
@item
|
||||
@sc{gnu} C++ does not bother using the space-saving methods for types whose
|
||||
encoding is a single character (like an integer, encoded as @samp{i}).
|
||||
This is useful in the most common cases (two @code{int}s would result in
|
||||
using three letters, instead of just @samp{ii}).

@c GNU C++:

@c * supports expanding inline functions in many situations,
|

@c including those which have static objects, use `for' statements,
|

@c and other situations. Part of this versatility is due to is
|

@c ability to not always generate temporaries for assignments.
|

@c * deliberately allows divide by 0 and mod 0, since [according
|
||||
@c to Wilson] there are actually situations where you'd like to allow
|
||||
@c such things. Note on most systems it will cause some sort of trap
|
||||
@c or bus error. Cfront considers it an error.
|
||||
@c * does [appear to] support nested classes within templates.
|
||||
@c * conversion functions among baseclasses are all usable by
|
||||
@c a class that's derived from all of those bases.
|
||||
@c * sizeof works even when the class is defined within its ()'s
|
||||
@c * conditional expressions work with member fns and pointers to
|

@c members.

<P>
|

Both C++ and Jave provide overloaded function and methods,
|
||||
which are methods with the same types but different parameter lists.
|
||||
Selecting the correct version is done at compile time.
|
||||
Though the overloaded functions have the same name in the source code,
|
||||
they need to be translated into different assembler-level names,
|
||||
since typical assemblers and linkers cannot handle overloading.
|
||||
This process of encoding the parameter types with the method name
|
||||
into a unique name is called <EM>name mangling</EM>. The inverse
|
||||
process is called <EM>demangling</EM>.
|
||||
|
||||
</P>
|
||||
<P>
|
||||
It is convenient that C++ and Java use compatible mangling schemes,
|
||||
since the makes life easier for tools such as gdb, and it eases
|
||||
integration between C++ and Java.
|
||||
|
||||
</P>
|
||||
<P>
|
||||
Note there is also a standard "Jave Native Interface" (JNI) which
|
||||
implements a different calling convention, and uses a different
|
||||
mangling scheme. The JNI is a rather abstract ABI so Java can call methods
|
||||
written in C or C++;
|
||||
we are concerned here about a lower-level interface primarily
|
||||
intended for methods written in Java, but that can also be used for C++
|
||||
(and less easily C).

That is followed by the number of parts in the qualified name.
|

If that number is 9 or less, it is emitted with no delimiters.

Otherwise, an underscore is written before and after the count.

Then follows each part of the qualified name, as described above.

A class template instantiation is encoded as the letter <SAMP>`t'</SAMP>,
|
||||
followed by the encoding of the template name, followed
|
||||
the number of template parameters, followed by encoding of the template
|
||||
parameters. If a template parameter is a type, it is written
|

as a <SAMP>`Z'</SAMP> followed by the encoding of the type.
|

</P>
|

<P>
|

A function template specialization (either an instantiation or an
|
||||
explicit specialization) is encoded by an <SAMP>`H'</SAMP> followed by the
|
||||
encoding of the template parameters, as described above, followed by
|
||||
an <SAMP>`_'</SAMP>, the encoding of the argument types template function (not the
|
||||
specialization), another <SAMP>`_'</SAMP>, and the return type. (Like the
|
||||
argument types, the return type is the return type of the function
|
||||
template, not the specialization.) Template parameters in the argument
|
||||
and return types are encoded by an <SAMP>`X'</SAMP> for type parameters, or a
|
||||
<SAMP>`Y'</SAMP> for constant parameters, and an index indicating their position
|
||||
in the template parameter list declaration.

<P>

C++ array types are mangled by emitting <SAMP>`A'</SAMP>, followed by
|
||||
the length of the array, followed by an <SAMP>`_'</SAMP>, followed by
|

the mangling of the element type. Of course, normally
|

array parameter types decay into a pointer types, so you
|

don't see this.

</P>

<P>
|

Java arrays are objects. A Java type <CODE>T[]</CODE> is mangled
|

as if it were the C++ type <CODE>JArray<T></CODE>.

For example <CODE>java.lang.String[]</CODE> is encoded as

<SAMP>`Pt6JArray1ZPQ34java4lang6String'</SAMP>.
