There are a number of benefits tied to the upstream / third-party checkasm version, including: - Improved long-term maintainability, code reuse with other projects, etc. - Vastly improved overall performance / runtime for benchmarking, due primarily to the ability to scale the runtime of each test to that test's complexity. - Much more robust statistical analysis of benchmarking results; including robust outlier rejection, an estimation of the histogram, and the ability to report the variance / stddev in addition to the (trimmed) mean. - Interactive HTML and JSON output formats in addition to CSV/TSV. - More readable and user-friendly output across the board, especially for failures and data dumps (e.g. also showing errors inside padding bytes). - Better cross-platform support, including dynamic fallback of timer implementations on ARM platforms, a better RISC-V harness, and more. There are multiple approaches to how we can solve the problem of integrating this third party checkasm into dav1d, but I think the hybrid approach of loading it as an external dependency, falling back to a meson wrap file, provides the best overall compromise. This avoids the messiness of git e.g. git submodules, while still allowing us to pin individual tags.
