...32-bit immediate Imm32PCRel Imm32S - 32-bit immediate that is sign extended to 64-bits. Imm64 Opsize ------ OpSizeFixed(default) - Operand size isn't mode dependent OpSize16 - 0x66 prefix required in 32-bit mode OpSize32 - 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...

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
