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>

36 <p> LLDB is improving on Linux. While the debugserver is not ported
Ashok Thirumurthi9bca2cf2013-05-24 19:25:33 +0000[diff] [blame]37 (to enable remote debugging) and debugging of multi-threaded programs is in its infancy, most
38 of the functionality, including the Python API and the command line tool,
39 is working on the x86_64 architecture, and partially working with i386.
40 FreeBSD is untested. ARM architectures on Linux are untested.
