  1. Open Debug Server Proposal(presented July 20, 2005)

  2. GDB Advantages GDB Drawbacks Proposal Going Forward Eclipse Debug I/F • GPL • Proprietary source code must be maintained separately. • Forces GDB and Target Server to be separate processes causing performance degradation. • C – code non object oriented, harder to maintain. • Modularity • Synchronous API (especially for run) • Prevents memory reads and writes while target is running. • Already open source • Robust implementation • 1000’s of test cases written • Plenty of customer feedback • Feature rich • E.g., support for many different object file formats. • Collaborate on creating reusable debug components. • Open Source. • Using eclipse plug-in framework. • Can be combined to create a debug server • Eclipse Debug I/F • CDT I/F • Compiled Language I/F? • Seek additional supporters willing to contribute components • Which eclipse project? • Device Debugging. • CDT. • Create a new project. Compiled Language Support Program Loader Breakpoint Manager Call Stack Walker Dis-Assembler Symbol Table Expression Evaluation MI I/F CDT CDI I/F • Debug Server • Symbol table • expression evaluation, • c-stepping • breakpoint management • etc… Debug Server Source Stepping GDB • CDT changes? • More extensibility • i.e., GDB is extensible, CDT is not. Symbol File Reader Target Server
