Given that Stefano is proposing to make the ISS a (per-hypervisor) constant we could consider just defining the Thumb and non-Thumb constants instead of doing all the construction with the __HVC_IMM stuff -- that would remove a big bit of the macroization.
It's not quite as simple as that -- emitting instructions using data directives is not endianness safe, and even in the cases where .long gives the right result for ARM, it gives the wrong result for 32-bit Thumb instructions if the opcode is given in human-readable order.
I was trying to solve the same problem for the kvm guys with some global macros -- I'm aiming to get a patch posted soon, so I'll make sure you're on CC.
That would be great, thanks!
