</div>

<div class="doc_text">

<p>This section lists changes to the LLVM development infrastructure. This

mostly impacts users who actively work on LLVM or follow development on

mainline, but may also impact users who leverage the LLVM build infrastructure

or are interested in LLVM qualification.</p>

<ul>

  <li>The default for <tt>make check</tt> is now to use

  the <a href="http://llvm.org/cmds/lit.html">lit</a> testing tool, which is

  part of LLVM itself. You can use <tt>lit</tt> directly as well, or use

  the <tt>llvm-lit</tt> tool which is created as part of a Makefile or CMake

  build (and knows how to find the appropriate tools). See the <tt>lit</tt>

  documentation and the <a href="http://blog.llvm.org/2009/12/lit-it.html">blog

  post</a>, and <a href="http://llvm.org/bugs/show_bug.cgi?id=5217">PR5217</a>

  for more information.</li>

  <li>The LLVM <tt>test-suite</tt> infrastructure has a new "simple" test format

  (<tt>make TEST=simple</tt>). The new format is intended to require only a

  compiler and not a full set of LLVM tools. This makes it useful for testing

  released compilers, for running the test suite with other compilers (for

  performance comparisons), and makes sure that we are testing the compiler as

  users would see it. The new format is also designed to work using reference

  outputs instead of comparison to a baseline compiler, which makes it run much

  faster and makes it less system dependent.</li>

  <li>Significant progress has been made on a new interface to running the

  LLVM <tt>test-suite</tt> (aka the LLVM "nightly tests") using

  the <a href="http://llvm.org/docs/lnt">LNT</a> infrastructure. The LNT

  interface to the <tt>test-suite</tt> brings significantly improved reporting

  capabilities for monitoring the correctness and generated code quality

  produced by LLVM over time.</li>

</ul>
