Any usable SIMD implementation?

[Martin Nowak via Digitalmars-d]

I'm currently working on a templated arrayop implementation (using RPN
to encode ASTs).
So far things worked out great, but now I got stuck b/c apparently none
of the D compilers has a working SIMD implementation (maybe GDC has but
it's very difficult to work w/ the 2.066 frontend).

https://github.com/MartinNowak/dmd/blob/arrayOps/src/arrayop.d

I don't want to do anything fancy, just unaligned loads, stores, and
integral mul/div. Is this really the current state of SIMD or am I
missing sth.?
