Support and enable LTO by default #1978
Comments

Try just adding the following to Cargo.toml: [profile.release]
lto = trueThat's how you generally add lto to a cargo project, I think. |

Forgot about this one. I n the meantime I elarned that you can also set the environment variable "CARGO_PROFILE_RELEASE_LTO" to "on" and that also enables LTO. Doing it with RUSTFLAGS as I did above is probably not a good idea. |

In order to reduce size and maybe increase performance, link-time-optimization could be enabled.
I tried these commands:
set RUSTFLAGS=-Clto
cargo install rustpython
I got this error:
error: cannot prefer dynamic linking when performing LTO
note: only 'staticlib', 'bin', and 'cdylib' outputs are supported with LTO
error: aborting due to previous error
