subtrees of the test suite directory tree are as follows:</p>
<ul>
<li><tt>llvm/test/Features</tt>
<p>This directory contains sample codes that test various features of the
LLVM language. These pieces of sample code are run through various
assembler, disassembler, and optimizer passes.</p>
</li>
<li><tt>llvm/test/Regression</tt>
<p>This directory contains regression tests for LLVM. When a bug is found
in LLVM, a regression test containing just enough code to reproduce the
problem should be written and placed somewhere underneath this directory.
In most cases, this will be a small piece of LLVM assembly language code,
often distilled from an actual application or benchmark.</p>
</li>
<li><tt>llvm/test</tt>
<p>This directory contains a large array of small tests
that exercise various features of LLVM and to ensure that regressions do not
occur. The directory is broken into several sub-directories, each focused on
a particular area of LLVM. A few of the important ones are:<ul>
<li><tt>Analysis</tt>: checks Analysis passes.</li>
<li><tt>Archive</tt>: checks the Archive library.</li>
<li><tt>Assembler</tt>: checks Assembly reader/writer functionality.</li>
<li><tt>Bytecode</tt>: checks Bytecode reader/writer functionality.</li>
<li><tt>CodeGen</tt>: checks code generation and each target.</li>
<li><tt>Features</tt>: checks various features of the LLVM language.</li>
<li><tt>Linker</tt>: tests bytecode linking.</li>
<li><tt>Transforms</tt>: tests each of the scalar, IPO, and utility
transforms to ensure they make the right transformations.</li>
<li><tt>Verifier</tt>: tests the IR verifier.</li>
</ul></p>
