--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
So here is how I would tackle this:
Put all the needed .i/.ii files in a response file.


$CC -c @files @options
$CC -r -o file.o @fileso @options=20

Since this is only at profile generated stage it is not as hard ...
Then start by reducing the needed .o files in `fileso` .
When that is finished. Update `files` to match `fileso`.
and then run delta (or another automated reducer) over the files in `files`.
Maybe even change -flto=3Dauto etc.=
