[llvm-dev] x86 instruction format which takes a single 64-bit immediate

I am attempting to create an instruction which takes a single 64-bit
immediate. This doesn't seem like a thing that would exist already (because
who needs an instruction which just takes an immediate?) How might I
implement this easily? Perhaps I could use a format which encodes a
register, which is then unused?

Thanks for the help.
