+ <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.
