| Greg Clayton | 04b78e9 | 2011-10-27 01:33:27 | [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>
|
| Greg Clayton | 491fbdf | 2010-06-10 02:48:57 | [diff] [blame] | 33 |
|
| 34 | <p>What works well:</p>
|
| 35 | <ul>
|
| 36 | <li>Process control, including external process control via debugserver
|
| 37 | (which is included as part of the lldb project)</li>
|
| 38 | <li>Breakpoints: Source-line, symbolic, C++ mangled names, module
|
| 39 | scoping</li>
|
| 40 | <li>Symbol reading and object file introspection</li>
|
| 41 | <li>Script bridging</li>
|
| 42 | <li>Thread inspection and stepping</li>

| 45 | <li>libedit powers the command line prompt and input

|
| 48 | <li>C++ support: method access, template support, dynamic types</li>
