--- Comment #15 from Matthias Andree <mandree@FreeBSD.org> ---
That would certainly fit MY bill. The thing with LTO is that in essence the
code generation moves into the "linker" stage which in fact, with LTO, is also
the final cross-module optimizing compiler stage... Earlier LTO implementations
were single-threaded and thus crap slow. (Tried that with graphics/rawtherapee
or g.../darktable, the latter of which has different LTO issues though)
