Working on some benchmarking. Posted some problems in the discord channel, but working through it now, and benchmarking with the CodeChecker tool using only clangsa. Is there an already established set of benchmarks y'all use somewhere? IIRC, there was some github repo with some benchmarks that I saw linked earlier.
