...Size32 - 0x66 prefix required in 16-bit mode OpSizeIgnored - 0x66 prefix should be ignored if present. Adsize ------ AdSizeX(default) - Address size prefix determined from memory operand registers encoded in modrm byte AdSize16 - Need a 0x67 prefix in 32-bit mode AdSize32 - Need a 0x67 prefix in 16-bit mode or 64-bit mode AdSize64 - Marks the 64-bit version of AdSize16/32 instructions. OpPrefix -------- NoPrfx(default) PS - Doesn't encode with a prefix, but 0x66/0xf2/0xf3 prefix are different instructions to the disassemble...

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
