This page describes the approach to use link time optimizations for package builds, starting with the bookworm development cycle.

Summary

Link time optimization (LTO) is a way to run optimizations across multiple translation units, enabling more opportunities for optimizations at link time. Each source file is translated to an intermediate representation, which is then used at link to build an executable or a shared object/library. The optimizations allow for faster code and smaller files.

Compiler flags for LTO are injected in dpkg-buildflags, and can be overridden in the package build. LTO is not enabled by default.

Implementation

Starting with dpkg 1.21.x, dpkg-buildflags will introduce a new optimization area, which adds the necessary flags to enable LTO. To enable LTO in the rules file, set

It can be explicitly disabled by

Disabling might be necessary, if the upstream project also provides an option to build with LTO.

Enabling LTO adds the flags -flto=auto -ffat-lto-objects to CFLAGS, CXXFLAGS, OBJCFLAGS ... and the flag -flto=auto to LDFLAGS. -ffat-lto-objects is used to generate both the intermediate representation and the object code in the object files, the latter needed to ship .o and .a files in packages. All intermediate code is stripped out by dh_strip.

Building with -ffat-lto-objects slows down the build a bit, however we have around 2000 packages shipping .o and .a files. If a package doesn't ship these object files, then a package can remove the -ffat-lto-objects option.

dpkg 1.21.x is not yet in the Debian archives. To test a LTO build, the flags have to be manually added, or you can use a dpkg test build found at

for your testing. Note that this build turns on LTO by default, as used for the archive test rebuild below.

Testing

An archive test rebuild was done to watch for regressions introduced by adding the LTO flags.

The LTO page on the Ubuntu wiki has test rebuilds for other architectures as well.

Regressions are build failures failing in the LTO build, but not in the reference build.

Known issues

Link time optimizations are already enabled in other Linux distributions, such as:
