Quite possibly (it'll be more efficient and it's intended for such use
cases) but as I said in my other reply that then has the issue that it
implicitly gives default values to all the registers so I'd expect we
still need to handle the cache initialisation explicitly (or
alternatively the hardware sync with the cache on startup).

Why does REGCACHE_FLAT assume that all registers have a default value of 0? Shouldn't it have the same behavior w.r.t. cache values as REGCACHE_RBTREE?
