<h1>LLVM/Clang Static Analyzer</h1>
|
|
|
|
<p>The LLVM/Clang static analyzer is a standalone tool that find bugs in C and
|
|
Objective-C programs. Currently the analyzer is invoked as a command-line tool.
|
|
It is intended to run in tandem with a build of a project or code base.</p>
|
|
|
|
<p>Here are some important points we ask you to consider when using the static
|
|
analyzer:</p>
|
|
|
|
<ul>
|
|
|
|
<li><b>This tool is <b>very early</b> in development.</b> There are many planned
|
|
enhancements to improve both the precision and scope of its analysis algorithms
|
|
as well as the kinds bugs it will find.</li>
|
|
|
|
<li><b>Static analysis can be much slower than compilation.</b> While the
|
|
analyzer is being designed to be as fast and light-weight as possible, please do
|
|
not expect it to be as fast as compiling a program (even with optimizations
|
|
enabled). Some of the algorithms needed to find bugs require in the worst case
|
|
exponential time. The analyzer runs in a reasonable amount of time by both
|
|
bounding the amount of checking work it will do as well as using clever
|
|
algorithms to reduce the amount of work it must do to find bugs.</li>
|
|
|
|
<li><b>False positives.</b> Static analysis is not perfect. It can falsely flag
|
|
bugs in a program where the code behaves correctly. Because some code checks
|
|
require more analysis precision than others, the frequency of false positives
|
|
can vary widely between different checks. Our eventual goal is to have the
|
|
analyzer have a low false positive rate for most code on all checks.</li>
|
|
</ul>
|
|
|
|
<h3>Please tell us about False Positives</h3>
|
|
|
|
<p>If you encounter a false positive, <b>please let us know</b> by <a
|
|
href="StaticAnalysisUsage.html#filingbugs">filing a bug report</a>. False
|
|
positives cannot be addressed unless we know about them.</p>
|
|
|
|
<h3>Want more bugs?</h3>
|
|
|
|
<p>If there are specific kinds of bugs you would like the tool to find,
|
|
please feel free to file <a href="StaticAnalysisUsage.html#filingbugs">feature
|
|
requests</a>.</p>
