core.simd woes

I see. So the __builtin_ia32_***() functions in gcc.builtins are 
architecture agnostic? I couldn't find much documentation about 
them on the web. Do you have any references you could pass on?

I guess it makes sense to just make std.simd the lib everyone 
uses for a "base-line" support of SIMD and let DMD do what it 
wants with it's core.simd lib. It sounds like gcc.builtins is 
just a layer above core.simd anyways. Although now it seems that 
DMD's std.simd will need a bunch of 'static if (architectureX) { 
... }' for every GDC builtin... wounder if later that shouldn't 
be moved to (and standerized) a 'core.builtins' module or 
something.

Thanks for the explanation.
