No. gcc internals assume that memory can be addressed in units of size BITS_PER_UNIT. The default for BITS_PER_UNIT is 8. I have written backends for machines for which that is not true. It is unusual, and there is only one official target with BITS_PER_UNIT != 8 (c4x), so there is often some minor breakage. Ian
