Oddly enough, I find myself rather disinclined to debug gdb...

I've noticed.

I should add that my application works absolutely fine on amd64 on Linux
and OS X; I'm not trying to *develop* on ARM, merely get an existing app
working. I'm reasonably confident that the logic is correct.

When developing an LLVM backend, I've used tracing to find out what the
compiler was doing while generating code; is the tracing logic built in
to the JIT? Can it be enabled? That should at least tell me *why* it's
picking the registers it is.
