I vaguely recall someone mentioned problems with atomic ops in the past, or was it 128-bit ints, caused implications for the codebase ?
TCG_OVERSIZED_GUEST, where 32-bit host running 64-bit guest cannot run the guest except in round-robin mode. It's not *that* much of a support burden, since we're not going to eliminate round-robin mode. But I do question whether we need to support 64-bit guests on 32-bit hosts at all. Retaining 32-bit on 32-bit allows arm32 to emulate i686, which I suspect, but have no proof, is the limit of what users actually want. r~
