@sunfish I haven't tried the transformation shown in this paper combined with LTO (which does cross-module inlining), but it seems best to just hide the accesses behind calls anyway.

@sunfish *especially* as you end up needing a volatile kind of memcpy for some kinds of MMIO buffer accesses, which is very easy for C compilers to mess with in unforseen ways.
