@coolbean @fiore @halva doesn't rust only support static linking or at least default to it? Not doing either lto or dynamic linking is kinda whack

@snacks @fiore @coolbean rustc has lto support but it fails when it fails when proc-macro crates are present

@snacks @fiore @coolbean it’s a nightly feature atm and evidently arch’es makepkg doesn’t like rust’s toolchain management very much

@fiore @snacks @coolbean it’s more complex than just dead code elimination

it’s more like compiler going over all translation units as if they were one and then applying optimization all across them
