[PATCH 0/19][GCC-8] aarch64: Backport outline atomics

[Pop, Sebastian]

Thanks Andre for the back-port to gcc-8.  Overall the patches look good to me.

Could you please move the patch "[PATCH 13/19][GCC-8] Aarch64: Fix shrinkwrapping interactions with atomics (PR92692)"
just after "[PATCH 8/19][GCC-8] aarch64: Implement TImode compare-and-swap"
such that the change that breaks TSAN builds gets fixed right away instead of waiting to get the fix after 4 more patches?

I would like to test the patches on Graviton2.
Could you please send me the git format-patch version?
It is hard to extract the patches from the mailing list without the patches getting scrambled.

Thanks,
Sebastian

    Hi,
    
    This series backports all the patches and fixes regarding outline
    atomics to the gcc-8 branch.
    
    Bootstrapped the series for aarch64-linux-gnu and regression tested.
    Is this OK for gcc-8?
