|
||
|
|
|
||
|
|
<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><span class="file">gcc</span></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:
