--- Comment #18 from Ard Biesheuvel <ard.biesheuvel at linaro dot org> ---
I have given this a spin with building the OVMF firmware (EDK2/Tianocore)

http://www.tianocore.org/edk2/

In my case, I need to pass -fno-asynchrounous-unwind-tables to actually get
some noticeable improvement, since the unwind info seems to hold some live
references to code that is otherwise unused. But with that added, it works
beautifully.

(using GCC 4.9.3 + binutils-gdb 7.10 branch)
