This is a quick tool that I've been using to build benchmarking builds for Deno. Usage: Build a benchmark `HEAD~1` and `origin/main` executable: ```sh deno run tools/build_bench.ts HEAD~1 origin/main ``` Build debug benchmark executables of the last three commits: ```sh deno run tools/build_bench.ts --profile debug HEAD HEAD~1 HEAD~2 ``` |
