| 23 | <p>LLDB has matured a lot in the last year and can be used for |
| 24 | C, C++ and Objective C development for x86_64, i386 and ARM debugging. |
| 25 | The entire public API is exposed though a framework on Mac OS X which |
| 26 | is used by Xcode, the lldb command line tool, and can also be used by |
| 27 | Python. The entire public API is exposed through script bridging which |
| 28 | allows LLDB to use an embedded Python script interpreter, as well as |
| 29 | having a Python module named "lldb" which can be used from Python |
| 30 | on the command line. This allows debug sessions to be scripted. It also |
| 31 | allows powerful debugging actions to be created and attached to a variety |
| 32 | of debugging workflows.</p> |

| 34 | <h1 class ="postheader">Linux Status</h1> |
| 35 | <div class="postcontent"> |
| 36 | <p> LLDB is improving on Linux. While the debugserver is not ported |
| 37 | (to enable remote debugging) and there are some stability issues, most |
| 38 | of the basic functionality, including the Python API and the commandline tool, |
| 39 | are working on i386/x86_64 architectures. ARM architectures on Linux are untested. |
| 40 | For more details, see the Features by OS section below. |

| 44 | <p> The table below shows a summary of the features that are available |
| 45 | on several platforms. In addition to Linux and Mac OS X, LLDB is also |
| 46 | known to work on FreeBSD. Windows support is under development. |
