Does gas really relax from 16-bit addresses to 32-bit address as necessary?
I played around briefly and it looks like gas will only emit 16-bit
addresses in 16-bit mode unless addr32 is prefixed. Even for an external
symbol it only emitted a 16-bit relocation type until I added addr32.
I wonder if

FWIW I could reproduce the 'movl foo,

And if not, please open a bug :-)
There are a few other missing cases that cause MC to produce code that
is more "relaxed" than it needs to be.
