- <li><p><em>Re-configure</em> <tt>llvm</tt> from the top level of
- each build tree (LLVM object directory tree) in which you want
- to run the test suite, just as you do before building LLVM.</p>
- <p>During the <em>re-configuration</em>, you must either: (1)
- have <tt>llvm-gcc</tt> you just built in your path, or (2)
- specify the directory where your just-built <tt>llvm-gcc</tt> is
- installed using <tt>--with-llvmgccdir=$LLVM_GCC_DIR</tt>.</p>
- <p>You must also tell the configure machinery that the test suite
- is available so it can be configured for your build tree:</p>
-<div class="doc_code">
-<pre>
-% cd $LLVM_OBJ_ROOT ; $LLVM_SRC_ROOT/configure [--with-llvmgccdir=$LLVM_GCC_DIR]
-</pre>
-</div>
- <p>[Remember that <tt>$LLVM_GCC_DIR</tt> is the directory where you
- <em>installed</em> llvm-gcc, not its src or obj directory.]</p>
- </li>
-
- <li><p>You can now run the test suite from your build tree as follows:</p>
-<div class="doc_code">
-<pre>
-% cd $LLVM_OBJ_ROOT/projects/test-suite
-% make
-</pre>
-</div>
- </li>
-</ol>
-<p>Note that the second and third steps only need to be done once. After you
-have the suite checked out and configured, you don't need to do it again (unless
-the test code or configure script changes).</p>

-<div>
-<p>In order to run the External tests in the <tt>test-suite</tt>
- module, you must specify <i>--with-externals</i>. This
- must be done during the <em>re-configuration</em> step (see above),
- and the <tt>llvm</tt> re-configuration must recognize the
- previously-built <tt>llvm-gcc</tt>. If any of these is missing or
- neglected, the External tests won't work.</p>
-<dl>
-<dt><i>--with-externals</i></dt>
-<dt><i>--with-externals=<<tt>directory</tt>></i></dt>
-</dl>
- This tells LLVM where to find any external tests. They are expected to be
- in specifically named subdirectories of <<tt>directory</tt>>.
- If <tt>directory</tt> is left unspecified,
- <tt>configure</tt> uses the default value
- <tt>/home/vadve/shared/benchmarks/speccpu2000/benchspec</tt>.
- Subdirectory names known to LLVM include:
- <dl>
- <dt>spec95</dt>
- <dt>speccpu2000</dt>
- <dt>speccpu2006</dt>
- <dt>povray31</dt>
- </dl>
- Others are added from time to time, and can be determined from
- <tt>configure</tt>.

-<!-- _______________________________________________________________________ -->
-<div>
-<p>In addition to the regular "whole program" tests, the <tt>test-suite</tt>
-module also provides a mechanism for compiling the programs in different ways.
-If the variable TEST is defined on the <tt>gmake</tt> command line, the test system will
-include a Makefile named <tt>TEST.<value of TEST variable>.Makefile</tt>.
-This Makefile can modify build rules to yield different results.</p>
-
-<p>For example, the LLVM nightly tester uses <tt>TEST.nightly.Makefile</tt> to
-create the nightly test reports. To run the nightly tests, run <tt>gmake
-TEST=nightly</tt>.</p>
-
-<p>There are several TEST Makefiles available in the tree. Some of them are
-designed for internal LLVM research and will not work outside of the LLVM
-research group. They may still be valuable, however, as a guide to writing your
-own TEST Makefile for any optimization or analysis passes that you develop with
-LLVM.</p>
