Hi everyone, I wanted to share a (hopefully useful) service for LLDB that I added recently:
If you go to https://teemperor.de/lldb-bench/ you'll now see graphs that show the instruction count and memory usage of the last LLDB nightlies (one per day). If you click on a graph you'll see a flame graph that shows how much time we spent in each function when running the benchmark. The graph should make it pretty obvious where the good places for optimizations are. You can see all graphs without the slide show under https://teemperor.de/lldb-bench/static.html. The source code of every benchmark can be found here: https://github.com/Teemperor/lldb-bench If you want to add a benchmark, just make a PR to that repository and I'll merge it. See the README of the repo for instructions. I'll add more benchmarks in the future, but you are welcome to add your own. Also, if you for some reason don't appreciate my amazing GNUplot markup skills and prefer your own graphs, you can just grab the raw benchmark data from here: https://teemperor.de/lldb-bench/data/ The data format is just the time, git-commit and the instruction-count/memoryInKB value (depending if it's a `.mem.dat` or a `.inst.dat`). On a side note: Today's spike in memory is related to changes in the build setup, not a LLDB change. I don't expect too many of these spikes to happen in the future because the benchmark framework is now hopefully stable enough.
