You're right, this fails for me too when I configure GCC for armv7-a or higher. It looks like a latent issue in that the Arm backend isn't able to recombine separate loads/stores into LDRD/STRD - eventhough it should really do that. There is a workaround - I can add back the logical DImode expanders which split off all memory operands before the DImode split (rather than the other way around).
Cheers, Wilco
