You could pack them like so.
float4 vec = loadUnaligned!float4(ptrToFloats);
float4 vec = loadAligned!float4(ptrToFloats);

The wrappers are only necessary because DMD/GDC/ldc have different SIMD implementations. Would be great if someone wrote a common basis library, unfortunately Manu's std.simd got stuck in progress.

D doesn't have macros and can't force inline, to inline w/o inliner you could use mixin templates, but relying on the inliner to do it's job would be cleaner.

Sounds like a feasible approach for phobos inclusion w/ prolly very little usability restrictions on the generic API wrapping those.

Yes, after talking to him this seems definitely a worthwhile pursuit. -- Andrei

Independent from Mir, a stable ABI for D which all compilers follow would be a tremendous win, especially from the perspective of shipping D stuff in Linux distributions.
So maybe this is worth attempting?
