Now here's an interesting target for D - this little beast could sell in 
millions, and could be the way that many youngsters start out as

Presumably LDC would be the quickest thing to get on there?

GDC on ARM has been working reasonably well for a while now (although
I get an ICE when building the latest trunk - still trying to come up
with enough information for a bug report). There's one major bug that
requires the section-anchors optimization to be disabled.

Last I tried LDC on ARM, it built and segfaulted when building the
standard library. GCC code generation for ARM is apparently
significantly better than LLVM, so I haven't looked much farther into
LDC.

I'm going to get my son in England to see if he can get one in January, 
then I'll see if I can get GDC to work on it.

LLVM can't be that bad since it's good enough for Apple and they're 
abandoning GCC in favor of Clang and LLVM.

I'm looking into it again, apparently it's improved dramatically on
ARM in the last few years. The compiler itself builds, but Druntime
needs some ARM-specific assembly. Working on that.

Yeah, both LLVM and Clang are progressed rapidly.

You may want to have a peek at GDC's druntime, as it is (mostly) 
ARM-ready. Could probably lift some code from there.

If I wanted that, I'd have to dig into GCC's platform specific source
(not GDC). Where pushing a thread's state onto the stack in GCC
consists of:
__builtin_unwind_init();

LLVM and DMD have to write some platform specific assembly.
Still, I could probably find GCC's assembly definitions for ARM.
