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

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

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