Consider that x86 x64 bit support was done in about one year and a half by
Walter single-handedly that is without freezing the other activity on DMD, of
course. Aside from emitting different sequences of instructions most IR-based
optimizations stay the same.
Doing an ARM back end wouldn't be that hard. It's much less complex than x86.
Most of the work would be deleting about half of the x86 code generator :-)
