<h3 class="section">7.4 C Language Testsuites</h3>
|
|
|
|
<p>GCC contains the following C language testsuites, in the
|
|
<samp>gcc/testsuite</samp> directory:
|
|
</p>
|
|
<dl compact="compact">
|
|
<dt><samp>gcc.dg</samp></dt>
|
|
<dd><p>This contains tests of particular features of the C compiler, using the
|
|
more modern ‘<samp>dg</samp>’ harness. Correctness tests for various compiler
|
|
features should go here if possible.
|
|
</p>
|
|
<p>Magic comments determine whether the file
|
|
is preprocessed, compiled, linked or run. In these tests, error and warning
|
|
message texts are compared against expected texts or regular expressions
|
|
given in comments. These tests are run with the options ‘<samp>-ansi -pedantic</samp>’
|
|
unless other options are given in the test. Except as noted below they
|
|
are not run with multiple optimization options.
|
|
</p></dd>
|
|
<dt><samp>gcc.dg/compat</samp></dt>
|
|
<dd><p>This subdirectory contains tests for binary compatibility using
|
|
<samp>lib/compat.exp</samp>, which in turn uses the language-independent support
|
|
(see <a href="compat-Testing.html#compat-Testing">Support for testing binary compatibility</a>).
|
|
</p></dd>
|
|
<dt><samp>gcc.dg/cpp</samp></dt>
|
|
<dd><p>This subdirectory contains tests of the preprocessor.
|
|
</p></dd>
|
|
<dt><samp>gcc.dg/debug</samp></dt>
|
|
<dd><p>This subdirectory contains tests for debug formats. Tests in this
|
|
subdirectory are run for each debug format that the compiler supports.
|
|
</p></dd>
|
|
<dt><samp>gcc.dg/format</samp></dt>
|
|
<dd><p>This subdirectory contains tests of the <samp>-Wformat</samp> format
|
|
checking. Tests in this directory are run with and without
|
|
<samp>-DWIDE</samp>.
|
|
</p></dd>
|
|
<dt><samp>gcc.dg/noncompile</samp></dt>
|
|
<dd><p>This subdirectory contains tests of code that should not compile and
|
|
does not need any special compilation options. They are run with
|
|
multiple optimization options, since sometimes invalid code crashes
|
|
the compiler with optimization.
|

</p></dd>

<dt><samp>gcc.dg/special</samp></dt>
|

<dd><p>FIXME: describe this.
|

</p>
|

</dd>
|
|
<dt><samp>gcc.c-torture</samp></dt>
|
|
<dd><p>This contains particular code fragments which have historically broken easily.
|
|
These tests are run with multiple optimization options, so tests for features
|
|
which only break at some optimization levels belong here. This also contains
|
|
tests to check that certain optimizations occur. It might be worthwhile to
|
|
separate the correctness tests cleanly from the code quality tests, but
|
|
it hasn’t been done yet.

</p></dd>
|
|
<dt><samp>gcc.c-torture/compile</samp></dt>
|
|
<dd><p>This testsuite contains test cases that should compile, but do not
|
|
need to link or run. These test cases are compiled with several
|
|
different combinations of optimization options. All warnings are
|
|
disabled for these test cases, so this directory is not suitable if
|
|
you wish to test for the presence or absence of compiler warnings.
|
|
While special options can be set, and tests disabled on specific
|
|
platforms, by the use of <samp>.x</samp> files, mostly these test cases
|
|
should not contain platform dependencies. FIXME: discuss how defines
|
|
such as <code>STACK_SIZE</code> are used.

</p></dd>
