Enables the use of a linker plugin during link time optimization. This
option relies on plugin support in the linker, which is available in gold
or in GNU ld 2.21 or newer.
This option enables the extraction of object files with GIMPLE bytecode out of
library archives. This improves the quality of optimization by exposing more
code the link time optimizer. This information specify what symbols
can be accessed externally (by non-LTO object or during dynamic linking).
Resulting code quality improvements on binaries (and shared libraries that do
use hidden visibility) is similar to @code{-fwhole-program}. See
@option{-flto} for a description on the effect of this flag and how to use it.

Enabled by default when LTO support in GCC is enabled and GCC was compiled
with a linker supporting plugins (GNU ld 2.21 or newer or gold).
