Hi all! This might've been covered beforehand/be redundant, but a talk at last week's Strangeloop (https://www.youtube.com/watch?v=r-TLSBdHe1A) covered coz-profiler (https://www.youtube.com/watch?v=r-TLSBdHe1A that's kinda magical—it finds and predicts what sort of optimizations would be useful, and how much of a throughput/latency increase it would provide. it could provide some useful measurements on rustc (but I suspect y'all might already have that data!)
it will likely need to be bindgen'd to work with Rust, but the author/presenter said that it should work with Rust with suprisingly little effort
Wow, that's interesting! It seems very related to this open issue we have: https://github.com/rust-lang/measureme/issues/39
I think coz fits the bill for this, then!
