|
| 22 | <p>LLDB supports a broad variety of basic debugging features such as
|
| 23 | reading DWARF, supporting step, next, finish, backtraces, etc. Some
|
| 24 | more interested bits are:</p>
|
| 25 |
|
| 26 | <ul>
|
| 27 | <li>Plug-in architecture for portability and extensibility:</li>
|
| 28 | <ul>
|
| 29 | <li>Object file parsers for executable file formats. Support currently
|
| 30 | includes Mach-O (32 and 64-bit) & ELF (32-bit).</li>
|
| 31 | <li>Object container parsers to extract object files contained within a file.
|
| 32 | Support currently includes universal Mach-O files & BSD Archives.
|
| 33 | </li>
|
| 34 | <li>Debug symbol file parsers to incrementally extract debug information from
|
| 35 | object files. Support currently includes DWARF & Mach-O symbol
|
| 36 | tables.</li>
|
| 37 | <li>Symbol vendor plug-ins collect data from a variety of different sources
|
| 38 | for an executable object.</li>
|
| 39 | <li>Disassembly plug-ins for each architecture. Support currently includes
|
| 40 | an LLVM disassembler for <a href="http://blog.llvm.org/2010/01/x86-disassembler.html">i386, x86-64</a>
|
| 41 | , & ARM/Thumb.</li>
|
| 42 | <li>Debugger plug-ins implement the host and target specific functions
|
| 43 | required to debug.</li>
|
| 44 | </ul>
|
| 45 | <li>SWIG-generated script bridging allows Python to access and control the
|
| 46 | public API of the debugger library.</li>
|
| 47 | <li>A remote protocol server, debugserver, implements Mac OS X debugging on
|
| 48 | i386 and x86-64.</li>
|
| 49 | <li>A command line debugger - the lldb executable itself.</li>
|
| 50 | <li>A framework API to the library.</li>
|
| 51 | </ul>
