I have done several VLIW compiler backends in GCC, so it is certainly
possible to use that as well. I generally did the initial port first,
not worrying about the VLIW-edness of the machine (other than things
like exposed pipelines that you have to get right by filling in NOPs
without doing the heavy scheduling), and then spent the second part of
the project getting the compiler and assembler tuned for the machine.
It depends on what type of constraints you have in the machine whether
the port is easy or hard.
