The valid options are:

* `false`: Performs "thin local LTO" which performs "thin" LTO on the local
crate only across its [codegen units](#codegen-units). No LTO is performed
if codegen units is 1 or [opt-level](#opt-level) is 0.
* `true` or `"fat"`: Performs "fat" LTO which attempts to perform
optimizations across all crates within the dependency graph.
* `"thin"`: Performs ["thin" LTO]. This is similar to "fat", but takes
substantially less time to run while still achieving performance gains
similar to "fat".
* `false`: Performs "thin local LTO" which performs "thin" LTO on the local
crate only across its [codegen units](#codegen-units). No LTO is performed
if codegen units is 1 or [opt-level](#opt-level) is 0.
* `"off"`: Disables LTO.

See the [linker-plugin-lto chapter] if you are interested in cross-language LTO.
