Craig, thanks for the quick response. That helps a lot. I had no clue they were buried in there, though I guess I should have looked harder -- the hex should have given me a clue, perhaps! For the sake of my own edification (and not taking up too much of your time) I will try to generate it myself. I've found the definition of the "I" class at line 358 of

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. Gus -------------- next part -------------- An HTML
