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> 33 </div> 34 <h1 class ="postheader">Linux Status</h1> 35 <div class="postcontent"> 36 <p> LLDB is improving on Linux. While the debugserver has not been ported 37 (to enable remote debugging) Linux is nearing feature completeness with Darwin 38 to debug x86_64 programs, and is partially working with i386 programs. 39 ARM architectures on Linux are untested. 40 For more details, see the Features by OS section below. 41 </div> 42 <h1 class ="postheader">FreeBSD Status</h1> 43 <div class="postcontent"> 44 <p> LLDB on FreeBSD lags behind the Linux implementation but is improving rapidly. 45 For more details, see the Features by OS section below. 46 </div> 47 <h1 class ="postheader">Features by OS</h1> 48 <div class="postcontent"> 49 <p> The table below shows a summary of the features that are available 50 on several platforms.
