X86 disassembler fails to handle 0x66 prefix?
Hello,
I have seen this bug for quite a while, and even in the latest code it
is still there: that is X86 disassembler does not handle 0x66 prefix
properly, if it is put behind 0xF3 prefix.
The below commands should return the same output, but not.
$ echo "0xf3 0x66 0xa5"|./build/bin/llvm-mc --disassemble
-triple=x86_64 -output-asm-variant=1
.text
rep
movsw word ptr es:[rdi], word ptr [rsi]
$ echo "0x66 0xf3 0xa6"...

...nds 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 that don't use an address en...

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.
