<p>Previously announced in the 2.4, 2.5, and 2.6 LLVM releases, the Clang project also
includes an early stage static source code analysis tool for <a

in C and Objective-C programs. The tool performs checks to find

<p>The <a href="http://clang-analyzer.llvm.org/">Clang Static Analyzer</a>
project is an effort to use static source code analysis techniques to
automatically find bugs in C and Objective-C programs (and hopefully <a
href="http://clang-analyzer.llvm.org/dev_cxx.html">C++ in the
future</a>!). The tool is very good at finding bugs that occur on specific
paths through code, such as on error conditions.</p>

<p>In the LLVM 2.7 time-frame, the analyzer core has made several major and
minor improvements, including better support for tracking the fields of
structures, initial support (not enabled by default yet) for doing
interprocedural (cross-function) analysis, and new checks have been added.

The LLVM Machine Code (MC) Toolkit project is ...
The LLVM Machine Code (aka MC) sub-project of LLVM was created to solve a number
of problems in the realm of assembly, disassembly, object file format handling,
and a number of other related areas that CPU instruction-set level tools work
in. It is a sub-project of LLVM which provides it with a number of advantages
over other compilers that do not have tightly integrated assembly-level tools.

MC Disassembler (with blog post), MCInstPrinter. Many X86 backend and AsmPrinter simplifications
Can transcode from GAS to intel syntax with "llvm-mc foo.s -output-asm-variant=1"
<p>2.7 includes major parts of the work required by the new MC Project. A few
targets have been refactored to support it, and work is underway to support a
native assembler in LLVM. This work is not complete in LLVM 2.7, but you has
made substantially more progress on LLVM mainline.</p>
<p>One minor example of what MC can do is to transcode an AT&amp;T syntax
X86 .s file into intel syntax. You can do this with something like:</p>
<pre>
llvm-mc foo.s -output-asm-variant=1 -o foo-intel.s
</pre>
