A quick review of src/runtime/arm-arch.c suggests that the only linux-specific piece is the pseudo-atomic-interrupted flag being a syscall number. The trap handlers should be fairly generic as-is, at least the ones that aren't #if 0'd out.

If you're porting to another OS, you'll need to re-evaluate the implementation of pseudo-atomic anyway, as it uses a conditional EABI Linux syscall to generate the pending-interrupt trap... Unless someone has changed that since I wrote it?

I think it would look cleaner if the trap handlers and the
pseudo_atomic_interrupted stuff was moved to arm-linux-os.c.
