Yeah, gcc's backend has much more advanced optimizations that dmd.  I've
actually looked at the assembly code output for different D snippets,
and often find that gdc's output has just several instructions where dmd
would output half a page of instructions (or an entire function together
with the entire call/return sequence).

Plus the gcc backend automatically gives you access to a whole slew of
target architectures that dmd would never have the manpower to support.
