mgeisler, My teammake Chris published a blog post describing how the #Android #Rust toolchain on Android has become 24% faster thanks to use of a single codegen unit, link-time optimization (#LTO), profile-guided optimization (#PGO), and the #BOLT tool. See https://android-developers.googleblog.com/2023/12/faster-rust-toolchains-for-android.html.
The
rustc
you get viarustup
is optimized similarly, Chris writes that the main difference is the compilation targets supported by the Android Rust toolchain.
