--- Comment #4 from Richard Biener <rguenth at gcc dot gnu.org> ---
Looks like a target issue to me, possibly caused by

2015-10-01  Kyrylo Tkachov  <kyrylo.tkachov@arm.com>

        Backport from mainline
        2015-06-09  Shiva Chen  <shiva0217@gmail.com>

        * sync.md (atomic_load<mode>): Add conditional code for lda/ldr
        (atomic_store<mode>): Likewise.

testcase needs reduction, working on trunk needs to be verified and the
regression bisected (in case it's not obvious).
