Link time optimizations are an optimization that helps with a single digit percent number optimizing both for smaller size, and better speed. These optimizations are available for some time now in GCC. Link time optimizations are also at least turned on in other distros like Fedora, OpenSuse

Debian bullseye will be based on a gcc-10 package taken from the gcc-10 upstream branch, and binutils based on a binutils package taken from the 2.35 branch. I'm planning to make gcc-10 the default after gcc-10 (10.2.0) is available (upstream targets mid July). binutils will be updated before
