| <div class="postcontent"> | |
| <p>LLDB is a next generation, high-performance debugger. It is built as a set | |
| of reusable components which highly leverage existing libraries in the | |
| larger LLVM Project, such as the Clang expression parser and LLVM | |
| disassembler.</p> | |
| <p>LLDB is in early development, but is mature enough to support basic | |
| debugging scenarios on Mac OS X in C, Objective-C and C++.</p> | |
| <p>All of the code in the LLDB project is available under the standard | |
| <a href="http://llvm.org/docs/DeveloperPolicy.html#license">LLVM | |
| License</a>, an open source "BSD-style" license.</p> | |

| <h1 class ="postheader">Why a new debugger?</h1> | |
| <div class="postcontent"> | |
| <p>In order to achieve our goals we decided to start with a fresh architecture | |
| that would support modern multi-threaded programs, handle debugging symbols | |
| in an efficient manner, use compiler based code knowledge and have plug-in | |
| support for functionality and extensions. Additionally we want the debugger | |
| capabilities to be available to other analysis tools, be they scripts or | |
| compiled programs, without requiring them to be GPL.</p> | |

| <h1 class ="postheader">Platform Support</h1> | |
| <div class="postcontent"> | |
| <p>LLDB is known to work on the following platforms, but ports to new | |
| platforms are welcome:</p> | |
| <ul> | |
| <li>Mac OS X i386 and x86-64</li> | |
| </ul> | |

| <h1 class ="postheader">Get it and get involved!</h1> | |
| <div class="postcontent"> | |
| <p>To check out the code, use:</p> | |
| <ul> | |
| <li>svn co http://llvm.org/svn/llvm-project/lldb/trunk lldb</li> | |
| </ul> | |
| <p>Note that LLDB currently only builds out of the box on Mac OS X with | |
| Xcode, but patches to improve portability are definitely welcome.</p> | |
| <p>Discussions about LLDB should go to the <a href="http://lists.cs.uiuc.edu/mailman/listinfo/lldb-dev">lldb-dev</a> mailing | |
| list. Commit messages for the lldb SVN module are automatically sent to the | |
| <a href="http://lists.cs.uiuc.edu/mailman/listinfo/lldb-commits">lldb-commits</a> | |
| mailing list, and this is also the preferred mailing list for patch | |
| submissions.</p> | |
