--- Comment #9 from Matthijs van Duin <matthijsvanduin at gmail dot com> ---
I can still reproduce the same test case with:  arm-linux-gnueabihf-gcc-8
(Debian 8-20180207-2) 8.0.1 20180207 (experimental) [trunk revision 257435]


-mfloat-abi=hard is implicit for arm-linux-gnueabihf, although overriding that
to -mfloat-abi=softfp produces exactly the same result for me.

(-mfloat-abi=soft completely disables all use of VFP/Neon hence obviously
suppresses this problem.)
