Dear GRUB folks,
Jacob integrated support for LTO (Link Time Optimization) to coreboot [1],
libpayload [2], and the payload *coreinfo* [3] resulting in a noticeable
reduction in the size.
So maybe GRUB would benefit too. Has anyone looked into this already?
Just adding `-flto` to the C flags fails.
$ make CFLAGS="-flto"
