--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Partition 0: size 4 align 8
        in      buf

That is wrong, it should have been two seperate ones.
Confirmed with:
gcc version 9.0.1 20190310 (experimental) [master revision
449a19898aa:0239598e3c8:8fe074cf790f632b22e59c24f102e528407bb04e] (GCC)

On aarch64-linux-gnu, I don't see any changes to the expand sources after that
point.

I could not reproduce it with Ubuntu's 7.3.0 but can with a non modified
version of GCC 7.3.0 on mips64-linux-gnu:
Partition 0: size 4 align 8
        in      buf
