It is very interesting and I hope someone can apply this to EDK2. I failed.
I created gcc-4.9.2 for linux-gnu target with --enable-plugin. And binutils
with --enable-plugins. Success.
But option -flto brakes building.
This advice
---------
2) Use gcc to launch the ld instead of invoking ld directly
-----------
failed because of build options for ld
-----
x86_64-linux-gnu-gcc: error: unrecognized command line option '-Map'
x86_64-linux-gnu-gcc: error: unrecognized command line option '-melf_x86_64'
x86_64-linux-gnu-gcc: error: unrecognized command line option
'--oformat=elf64-x86-64'
x86_64-linux-gnu-gcc: error: unrecognized command line option '-('
-----
and so on.
Using ld I got another problems like error adding symbols: Bad value
As well as losing _ModuleEntryPoint or .text section at all.
I pass waiting for a good news.
