cases, this takes care of the problem. To do this, just type <tt>make
clean</tt> and then <tt>make</tt> in the directory that fails to build.
<p>
<dt><b>I've built LLVM and am testing it, but the tests freeze.</b>
<dd>
This is most likely occurring because you built a profile or release
(optimized) build of LLVM and have not specified the same information on
the <tt>gmake</tt> command line.
<p>
For example, if you built LLVM with the command:
<p>
<tt>gmake ENABLE_PROFILING=1</tt>
<p>
...then you must run the tests with the following commands:
<p>
<tt>cd llvm/test<br>gmake ENABLE_PROFILING=1</tt>
<p>
<dt><b>Why do test results differ when I perform different types of
builds?</b>
<dd>
The LLVM test suite is dependent upon several features of the LLVM tools
and libraries.
<p>
First, the debugging assertions in code are not enabled in optimized or
profiling builds. Hence, tests that used to fail may pass.
<p>
Second, some tests may rely upon debugging options or behavior that is
only available in the debug build. These tests will fail in an optimized
or profile build.
