x86 instruction format which takes a single 64-bit immediate
Copy Ii32 in X86InstrFormats.td rename to Ii64 and change Imm32 to Imm64.
Instantiate your instruction inheriting from Ii64. Pass RawFrm to the form
parameter.
Initial documentation for the encoding system is attached.

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.
