x86 instruction format which takes a single 64-bit immediate
...- Classifies how operands are encoded into the various fields that encode operands, i.e. modrm.reg, modrm.rm, vex.vvvv, rex.r, rex.x, rex.b, etc. See format list below. ImmT - Determines the size of the immediate, if any at the end of the instruction. OpSize - Used to inciate instructions that need a 0x66 operand size prefix to encode 16-bit operands in 32 mode or 32-bit operands in 16-bit mode. AdSize - Used to mark instructions that need to emit a 0x67 address size prefix in 32-bit mode or 16-bit mode. This is rarely used and is only needed by instructions th...

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