[[bbv2.builtin.features.lto]]`lto`::
*Allowed values:* `on`.
+
Enables link time optimizations (also known as interprocedural optimizations or
whole-program optimizations). Currently supported toolsets are <<GNU {CPP}>>,
clang and <<Microsoft Visual {CPP}>>. The feature is optional.

[[bbv2.builtin.features.lto-mode]]`lto-mode`::
*Subfeature of* `lto`
+
*Allowed values:* `full`, `thin`, `fat`.
+
Specifies the type of LTO to use.
+
`full`::: Use the monolithic LTO: on linking all input is merged into a single
  module.
`thin`::: Use clang's ThinLTO: each compiled file contains a summary of the
  module, these summaries are merged into a single index. This allows to avoid
  merging all modules together, which greatly reduces linking time.
`fat`::: Produce gcc's fat LTO objects: compiled files contain both the
  intermidiate language suitable for LTO and object code suitable for regular
  linking.
