[BUG] MOV (A0-A3) imm len problem

MOV (A0-A3) opcode's is always 64-bit in 64-bit mod, this conclusion comes from HxD:

When it disassembles this machine code, the imm len is 8 bytes,

Hi, thanks for sharing.

How did you generate the machine code? Is that hand-written or assembled?
That's interesting anyhow. But I'm not so sure is correct, at a quick look.

Anyhow, reading the quote from Intel seems not wrong what I did: is not mentioned the qword.

Should be interesting try with LLVM, or maybe try to use the instruction disassembler from Intel.
