| |
| <p>The current state of the art in open source debuggers are that |
| they work in the common cases for C applications, but don't |
| handle many "hard cases" properly. For example, C++ expression |
| parsing, handling overloading, templates, multi-threading, and |
| other non-trivial scenarios all work in some base cases, but |
| don't work reliably.</p> |
| |
| <p>The goal of LLDB is to provide an amazing debugging experience that "just |
| works". We aim to solve these long-standing problems where debuggers get |
| confused, so that you can think about debugging your problem, not |
| about deficiencies in the debugger.</p> |
| |
| <p>With a long view, there is no good reason for a debugger to |
| reinvent its own C/C++ parser, type system, know all the |
| target calling convention details, implement its own disassembler, |
| etc. By using the existing libraries vended by the LLVM |
| project, we believe that many of these problems will be defined |
| away, and the debugger can focus on important issues like |
| process control, efficient symbol reading and indexing, thread |
| management, and other debugger-specific problems.</p> |
| |
| <p>Some more specific goals include:</p> |
| |
| <ul> |
| <li>Build libraries for inclusion in IDEs, command line tools, and |
| other analysis tools</li> |
| <li>High performance and efficient memory use</li> |
| <li>Extensible: Python scriptable and use a plug-in architecture</li> |
| <li>Reuse existing compiler technology where it makes sense</li> |
| <li>Excellent multi-threaded debugging support</li> |
| <li>Great support for C, Objective-C and C++</li> |
| <li>Retargetable to support multiple platforms</li> |
| <li>Provide a base for debugger research and other innovation</li> |
| </ul> |
