This includes -<a href="http://www.gnu.org/software/dejagnu/">DejaGnu</a>, Tcl, and Expect; -the DejaGnu site has links to these. - - <p>If the directories where <samp><span class="command">runtest</span></samp> and <samp><span class="command">expect</span></samp> were -installed are not in the <samp><span class="env">PATH</span></samp>, you may need to set the following -environment variables appropriately, as in the following example (which -assumes that DejaGnu has been installed under <samp><span class="file">/usr/local</span></samp>): - -<pre class="smallexample"> TCL_LIBRARY = /usr/local/share/tcl8.0 - DEJAGNULIBS = /usr/local/share/dejagnu -</pre> - <p>(On systems such as Cygwin, these paths are required to be actual -paths, not mounts or links; presumably this is due to some lack of -portability in the DejaGnu code.) - - <p>Finally, you can run the testsuite (which may take a long time): -<pre class="smallexample"> cd <var>objdir</var>; make -k check -</pre> - <p>This will test various components of GCC, such as compiler -front ends and runtime libraries. While running the testsuite, DejaGnu -might emit some harmless messages resembling -‘<samp><span class="samp">WARNING: Couldn't find the global config file.</span></samp>’ or -‘<samp><span class="samp">WARNING: Couldn't find tool init file</span></samp>’ that can be ignored. - - <p>If you are testing a cross-compiler, you may want to run the testsuite -on a simulator as described at <a href="http://gcc.gnu.org/simtest-howto.html">http://gcc.gnu.org/simtest-howto.html</a>. - -<h3 class="section"><a name="TOC0"></a>How can you run the testsuite on selected tests?</h3> - -<p>In order to run sets of tests selectively, there are targets -‘<samp><span class="samp">make check-gcc</span></samp>’ and language specific ‘<samp><span class="samp">make check-c</span></samp>’, -‘<samp><span class="samp">make check-c++</span></samp>’, ‘<samp><span class="samp">make check-fortran</span></samp>’, ‘<samp><span class="samp">make check-java</span></samp>’, -‘<samp><span class="samp">make check-ada</span></samp>’, ‘<samp><span class="samp">make check-objc</span></samp>’, ‘<samp><span class="samp">make check-obj-c++</span></samp>’, -‘<samp><span class="samp">make check-lto</span></samp>’ -in the <samp><span class="file">gcc</span></samp> subdirectory of the object directory. You can also -just run ‘<samp><span class="samp">make check</span></samp>’ in a subdirectory of the object directory. - - <p>A more selective way to just run all <samp><span class="command">gcc</span></samp> execute tests in the -testsuite is to use - -<pre class="smallexample"> make check-gcc RUNTESTFLAGS="execute.exp <var>other-options</var>" -</pre> - <p>Likewise, in order to run only the <samp><span class="command">g++</span></samp> “old-deja” tests in -the testsuite with filenames matching ‘<samp><span class="samp">9805*</span></samp>’, you would use - -<pre class="smallexample"> make check-g++ RUNTESTFLAGS="old-deja.exp=9805* <var>other-options</var>" -</pre> - <p>The <samp><span class="file">*.exp</span></samp> files are located in the testsuite directories of the GCC -source, the most important ones being <samp><span class="file">compile.exp</span></samp>, -<samp><span class="file">execute.exp</span></samp>, <samp><span class="file">dg.exp</span></samp> and <samp><span class="file">old-deja.exp</span></samp>. -To get a list of the possible <samp><span class="file">*.exp</span></samp> files, pipe the -output of ‘<samp><span class="samp">make check</span></samp>’ into a file and look at the -‘<samp><span class="samp">Running ... .exp</span></samp>’ lines. - -<h3 class="section"><a name="TOC1"></a>Passing options and running multiple testsuites</h3> - -<p>You can pass multiple options to the testsuite using the -‘<samp><span class="samp">--target_board</span></samp>’ option of DejaGNU, either passed as part of -‘<samp><span class="samp">RUNTESTFLAGS</span></samp>’, or directly to <samp><span class="command">runtest</span></samp> if you prefer to -work outside the makefiles. For example, - -<pre class="smallexample"> make check-g++ RUNTESTFLAGS="--target_board=unix/-O3/-fmerge-constants" -</pre> - <p>will run the standard <samp><span class="command">g++</span></samp> testsuites (“unix” is the target name -for a standard native testsuite situation), passing -‘<samp><span class="samp">-O3 -fmerge-constants</span></samp>’ to the compiler on every test, i.e., -slashes separate options. - - <p>You can run the testsuites multiple times using combinations of options -with a syntax similar to the brace expansion of popular shells: - -<pre class="smallexample"> ..."--target_board=arm-sim\{-mhard-float,-msoft-float\}\{-O1,-O2,-O3,\}" -</pre> - <p>(Note the empty option caused by the trailing comma in the final group.) -The following will run each testsuite eight times using the ‘<samp><span class="samp">arm-sim</span></samp>’ -target, as if you had specified all possible combinations yourself: - -<pre class="smallexample"> --target_board='arm-sim/-mhard-float/-O1 \ - arm-sim/-mhard-float/-O2 \ - arm-sim/-mhard-float/-O3 \ - arm-sim/-mhard-float \ - arm-sim/-msoft-float/-O1 \ - arm-sim/-msoft-float/-O2 \ - arm-sim/-msoft-float/-O3 \ - arm-sim/-msoft-float' -</pre> - <p>They can be combined as many times as you wish, in arbitrary ways. This -list: - -<pre class="smallexample"> ..."--target_board=unix/-Wextra\{-O3,-fno-strength\}\{-fomit-frame,\}" -</pre> - <p>will generate four combinations, all involving ‘<samp><span class="samp">-Wextra</span></samp>’. - - <p>The disadvantage to this method is that the testsuites are run in serial, -which is a waste on multiprocessor systems. For users with GNU Make and -a shell which performs brace expansion, you can run the testsuites in -parallel by having the shell perform the combinations and <samp><span class="command">make</span></samp> -do the parallel runs. Instead of using ‘<samp><span class="samp">--target_board</span></samp>’, use a -special makefile target: - -<pre class="smallexample"> make -j<var>N</var> check-<var>testsuite</var>//<var>test-target</var>/<var>option1</var>/<var>option2</var>/... -</pre> - <p>For example, - -<pre class="smallexample"> make -j3 check-gcc//sh-hms-sim/{-m1,-m2,-m3,-m3e,-m4}/{,-nofpu} -</pre> - <p>will run three concurrent “make-gcc” testsuites, eventually testing all -ten combinations as described above. Note that this is currently only -supported in the <samp><span class="file">gcc</span></samp> subdirectory. (To see how this works, try -typing <samp><span class="command">echo</span></samp> before the example given here.) - -<h3 class="section"><a name="TOC2"></a>Additional testing for Java Class Libraries</h3> - -<p>The Java runtime tests can be executed via ‘<samp><span class="samp">make check</span></samp>’ -in the <samp><var>target</var><span class="file">/libjava/testsuite</span></samp> directory in -the build tree. - - <p>The <a href="http://sourceware.org/mauve/">Mauve Project</a> provides -a suite of tests for the Java Class Libraries.
