When presented with a C or C++ +source program, GCC parses the program, performs semantic analysis +(including the generation of error messages), and then produces the +internal representation described here. This representation contains a +complete representation for the entire translation unit provided as +input to the front end. This representation is then typically processed +by a code-generator in order to produce machine code, but could also be +used in the creation of source browsers, intelligent editors, automatic +documentation generators, interpreters, and any other programs needing +the ability to process C or C++ code. +</p> +<p>This section explains the internal representation. In particular, it +documents the internal representation for C and C++ source +constructs, and the macros, functions, and variables that can be used to +access these constructs. The C++ representation is largely a superset +of the representation used in the C front end. There is only one +construct used in C that does not appear in the C++ front end and that +is the GNU “nested function” extension. Many of the macros documented +here do not apply in C because the corresponding language constructs do +not appear in C. +</p> +<p>The C and C++ front ends generate a mix of GENERIC trees and ones +specific to C and C++. These language-specific trees are higher-level +constructs than the ones in GENERIC to make the parser’s job easier. +This section describes those trees that aren’t part of GENERIC as well +as aspects of GENERIC trees that are treated in a language-specific +manner. +</p> +<p>If you are developing a “back end”, be it is a code-generator or some +other tool, that uses this representation, you may occasionally find +that you need to ask questions not easily answered by the functions and +macros available here. If that situation occurs, it is quite likely +that GCC already supports the functionality you desire, but that the +interface is simply not documented here. In that case, you should ask +the GCC maintainers (via mail to <a href="mailto:gcc@gcc.gnu.org">gcc@gcc.gnu.org</a>) about +documenting the functionality you require. Similarly, if you find +yourself writing functions that do not deal directly with your back end, +but instead might be useful to other people using the GCC front end, you +should submit your patches for inclusion in GCC. +</p> +<table class="menu" border="0" cellspacing="0"> +<tr><td align="left" valign="top">• <a href="Types-for-C_002b_002b.html#Types-for-C_002b_002b" accesskey="1">Types for C++</a>:</td><td> </td><td align="left" valign="top">Fundamental and aggregate types. +</td></tr> +<tr><td align="left" valign="top">• <a href="Namespaces.html#Namespaces" accesskey="2">Namespaces</a>:</td><td> </td><td align="left" valign="top">Namespaces. +</td></tr> +<tr><td align="left" valign="top">• <a href="Classes.html#Classes" accesskey="3">Classes</a>:</td><td> </td><td align="left" valign="top">Classes. +</td></tr> +<tr><td align="left" valign="top">• <a href="Functions-for-C_002b_002b.html#Functions-for-C_002b_002b" accesskey="4">Functions for C++</a>:</td><td> </td><td align="left" valign="top">Overloading and accessors for C++. +</td></tr> +<tr><td align="left" valign="top">• <a href="Statements-for-C-and-C_002b_002b.html#Statements-for-C-and-C_002b_002b" accesskey="5">Statements for C and C++</a>:</td><td> </td><td align="left" valign="top">Statements specific to C and C++. +</td></tr> +<tr><td align="left" valign="top">• <a href="C_002b_002b-Expressions.html#C_002b_002b-Expressions" accesskey="6">C++ Expressions</a>:</td><td> </td><td align="left" valign="top">From <code>typeid</code> to <code>throw</code>. +</td></tr> +</table> + +<hr> +<div class="header"> +<p> +Previous: <a href="Language_002ddependent-trees.html#Language_002ddependent-trees" accesskey="p" rel="previous">Language-dependent trees</a>, Up: <a href="GENERIC.html#GENERIC" accesskey="u" rel="up">GENERIC</a> [<a href="index.html#SEC_Contents" title="Table of contents" rel="contents">Contents</a>][<a href="Option-Index.html#Option-Index" title="Index" rel="index">Index</a>]</p> +</div> + + + +</body> +</html> |
