<div class="postcontent">
<p>The current state of the art in open source debuggers are that
they work in the common cases for C applications, but don't
handle many "hard cases" properly. For example, C++ expression
parsing, handling overloading, templates, multi-threading, and
other non-trivial scenarios all work in some base cases, but
don't work reliably.</p>
<p>The goal of LLDB is to provide an amazing debugging experience that "just
works". We aim to solve these long-standing problems where debuggers get
confused, so that you can think about debugging your problem, not
about deficiencies in the debugger.</p>
<p>With a long view, there is no good reason for a debugger to
reinvent its own C/C++ parser, type system, know all the
target calling convention details, implement its own disassembler,
etc. By using the existing libraries vended by the LLVM
project, we believe that many of these problems will be defined
away, and the debugger can focus on important issues like
process control, efficient symbol reading and indexing, thread
management, and other debugger-specific problems.</p>
<p>Some more specific goals include:</p>
<li>Build libraries for inclusion in IDEs, command line tools, and
other analysis tools</li>
<li>High performance and efficient memory use</li>
<li>Extensible: Python scriptable and use a plug-in architecture</li>
<li>Reuse existing compiler technology where it makes sense</li>
<li>Excellent multi-threaded debugging support</li>
<li>Great support for C, Objective-C and C++</li>
<li>Retargetable to support multiple platforms</li>
<li>Provide a base for debugger research and other innovation</li>
