I agree that it has caused a huge number of compiler headaches. I
suppose I'd be okay with disabling it by default, but like I said to
Siarhei I would like to keep it working on x86 because that's a much
easier way to test and prototype code than using slow iwMMXt/loongson
systems. Though, I do fear that if we disable it by default it'll just
get close to zero testing.
