Hi, I'd like to give a talk about GDB Performance Testing. I talked about it in July on GNU Cauldron, but it should be OK to talk again on hellogcc. Title: Performance Testing for GDB Abstract: GDB development process has no standard mechanism to show the performance of GDB snapshot or release is improved or worsened. Performance regressions do show up periodically. We recently add a new performance testing framework in GDB. In this session, we introduce this performance testing framework and show how do we use it to track GDB performance during development. Then, we show writing performance test cases on top of this framework and performance problems exposed by these cases. Finally, we discuss about adding more test cases and fixing other performance problems in the future.
