| <h4 class="subsubsection">6.3.8.1 The Front End <samp><var>language</var></samp> Directory</h4> |
| |
| <p>A front end <samp><var>language</var></samp> directory contains the source files |
| of that front end (but not of any runtime libraries, which should be |
| outside the <samp>gcc</samp> directory). This includes documentation, and |
| possibly some subsidiary programs built alongside the front end. |
| Certain files are special and other parts of the compiler depend on |
| their names: |
| </p> |
| <dl compact="compact"> |
| <dt><samp>config-lang.in</samp></dt> |
| <dd><p>This file is required in all language subdirectories. See <a href="Front-End-Config.html#Front-End-Config">The Front End <samp>config-lang.in</samp> File</a>, for details of |
| its contents |
| </p></dd> |
| <dt><samp>Make-lang.in</samp></dt> |
| <dd><p>This file is required in all language subdirectories. See <a href="Front-End-Makefile.html#Front-End-Makefile">The Front End <samp>Make-lang.in</samp> File</a>, for details of its |
| contents. |
| </p></dd> |
| <dt><samp>lang.opt</samp></dt> |
| <dd><p>This file registers the set of switches that the front end accepts on |
| the command line, and their <samp>--help</samp> text. See <a href="Options.html#Options">Options</a>. |
| </p></dd> |
| <dt><samp>lang-specs.h</samp></dt> |
| <dd><p>This file provides entries for <code>default_compilers</code> in |
| <samp>gcc.c</samp> which override the default of giving an error that a |
| compiler for that language is not installed. |
| </p></dd> |
| <dt><samp><var>language</var>-tree.def</samp></dt> |
| <dd><p>This file, which need not exist, defines any language-specific tree |
| codes. |
