Crystal: Fast as C, Slick as Ruby

Those kinds of systems won't get compilers for something other than C/C++ or maybe Ada for a long time. Usually you're stuck with a compiler from the chip vendor that kinda-sorta supports C.

Indeed, and you'll probably also need a special-purpose RT OS stack (or have to write your own/go without).

EDIT: I'd also add that this is such a niche[1] area of programming that expecting any mainstream language to meaningfully support it is... optimisitic and that mainstream languages shouldn't try to support it. (Soft real-time may be reasonable, but I believe that can be achieved with GC as demonstrated by the Azul JVM.)

[1] Niche, but obviously important, but perhaps not lucrative enough for anything to displace C or perhaps Ada -- given that these industries tend to be extremely conservative. (I wonder if ATS is used, though. Can't claim it's pretty, but proof seems like it would be a good thing for these systems?)

Special versions of Java also get into this niche. Check the PTC Java compilers or Websphere Real Time one from IBM.

Before Aonix got bought by PTC they had a few contracts for weapons control for missiles and battle cruisers.
