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