[coreboot] Thoughts or conclusions on coreboot and link time optimization (LTO)?

[Paul Menzel]

Dear coreboot folks,

in #coreboot on <irc.freenode.net> Stefan mentioned that link time
optimization (LTO) [1] might yield some speed improvements for coreboot
as the resulting firmware image might be smaller and therefore it takes
less time to read it from flash.

As LTO has been greatly improved in GCC 4.9.0 and is all over the news,
has somebody already experimented with LTO or created patches or tools
for testing?

Is somebody able to share conclusions already? That’d be very
interesting.

Thanks,

Paul
