From what I've understood of this - it's transpiling the x86 code to ARM on the fly. I honestly would have thought it wasn't possible but hearing that they're doing it - it will be a monumental effort, but very feasible. The best part is that once they've gotten CRT and cdecl instructions working - actual application support won't be far behind. The biggest challenge will likely be inserting memory barriers correctly - a spinlock implemented in x86 assembly is highly unlikely to work correctly without a lot of effort to recognize and transpile that specific structure as a whole.
