Thanks.

A thought: Since I have an x86-64 box, could I cross-compile D 
programs for AArch64 output?  (This might sound a bit mad, but my 
aim is to look at the quality of the code generated by GDC vs 
LDC, and also to learn a AArch64 asm.) And I am a true D convert.

I would need the appropriate magic runes / switches for that kind 
of cross-code generation. Could someone perhaps help me with 
that? It would save me a lot of struggle.
