Enum rustc_ap_rustc_session::config::Lto

pub enum Lto {
    No,
    Thin,
    ThinLocal,
    Fat,
}

This is what the LtoCli values get mapped to after resolving defaults and and taking other command line options into account.

Note that linker plugin-based LTO is a different mechanism entirely.

Variants

No

Don’t do any LTO whatsoever.

Thin

Do a full-crate-graph (inter-crate) LTO with ThinLTO.

ThinLocal

Do a local ThinLTO (intra-crate, over the CodeGen Units of the local crate only). This is only relevant if multiple CGUs are used.

Fat

Do a full-crate-graph (inter-crate) LTO with “fat” LTO.
