Ashok Thirumurthi5c8dbc42013-06-12 14:26:58 +0000[diff] [blame]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>

Ashok Thirumurthi2f27f402013-06-07 19:21:45 +0000[diff] [blame]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.
Ed Maste9ec50222013-07-24 13:51:45 +0000[diff] [blame]39 ARM architectures on Linux are untested.
