Comment Comment by meinersbur My first contribution to a Rust codebase was <https://github.com/mozilla/sccache/commit/da2934fcc2ed2a4ae2...>. It is adding the -fminimize-whitespace flag to the preprocessor command when available (New in Clang 14, <https://releases.llvm.org/14.0.0/tools/clang/docs/ReleaseNot...>). The equivalent ccache patch is still pending <https://github.com/ccache/ccache/pull/815>.When using the disk cache, ccache is still faster on cache hits due to also checking the hash of all input files (called a manifest) before even executing the preprocessor. It also can just clone/hardlink the file in the cache instead of copying it. parent meinersbur 4 years ago
