Unfortunately, there is no proper ABI standard document for LM32. But we
(Michael, Werner and I) think that it should work with alignment = 4
everywhere.

The LM32 architecture manual simply states: "All memory accesses must be
aligned to the size of the access", and there is no hardware support whatsoever
for 64-bit numbers. I would find it surprising if parts of the ABI had
alignment requirements of more than 32-bit.
