|
|
<p>The <samp><span class="file">config.build</span></samp> file contains specific rules for particular systems
|
||
|
|
which GCC is built on. This should be used as rarely as possible, as the
|
||
|
|
behavior of the build system can always be detected by autoconf.
|
||
|
|
|
||
|
|
<p>The <samp><span class="file">config.host</span></samp> file contains specific rules for particular systems
|
||
|
|
which GCC will run on. This is rarely needed.
|
||
|
|
|
||
|
|
<p>The <samp><span class="file">config.gcc</span></samp> file contains specific rules for particular systems
|
||
|
|
which GCC will generate code for. This is usually needed.
|
||
|
|
|
||
|
|
<p>Each file has a list of the shell variables it sets, with descriptions, at the
|
||
|
|
top of the file.
|
||
|
|
|
||
|
|
<p>FIXME: document the contents of these files, and what variables should
|
||
|
|
be set to control build, host and target configuration.
