I'm not sure if this one falls in scope, but it would be lovely to get the kinds of results you get from https://github.com/iai-callgrind/iai-callgrind (a maintained fork of the original iai), but with divans nice interface / register-anywhere system!

Using these main! macros and listing all of the test function names there really feels primitive after being spoiled by divan!

Pretty good context as to why time vs cpu instruction count measurements matter: https://youtu.be/qfknfCsICUM?t=1229 😊
