--- Comment #3 from Jim Wilson <wilson at gcc dot gnu.org> ---
I was able to reproduce this with an armhf cross compiler, compiling the
testcase with -O -mfpu=neon-vfpv4. It is not broken in gcc-4.9.2. It was
fixed by this patch
https://gcc.gnu.org/ml/gcc-patches/2014-02/msg01595.html
which has this ChangeLog entry
2014-03-03 Ramana Radhakrishnan <ramana.radhakrishnan@arm.com>
* config/arm/neon.md (*movmisalign<mode>): Legitimize addresses
not handled by recognizers.
I don't know offhand if this is worth backporting to gcc-4.8.x.
