Hello everyone! I am wondering if there is any tooling within the ecosystem that would enable me to investigate why exactly compilation is taking as long as it is. clang has something like -ftime-report which gives me hints into which translation units are taking as long as they are and I am curious to find similar tooling for zig.

Relatively new to the language so would love guidance. Thanks!

-ftime-report (on zig build iirc)
