Another really good example of cross compilation is x86 -> arm.  I don't have actual statistics to back it other than my own where essentially ALL of my arm development for the last 2ish years has been like that.  Cross-compilation between platforms is increasingly the norm.  x86 to x86 is about the only place it isn't done.

That's a misjudgement, go get's a lot out of having full and simple
cross-compilation support built-in. Makes packaging/releasing a swift
and is one of the reasons it's getting a lot of traction.

Their support is also simpler than using different cross-compilers for
each target, not sure if that's possible w/ GDC/LDC's multilibs.

Biggest hurdle seems to be cross-OS linking, not sure how to best
address this. The go people typically use static linking to avoid that
problem.
