RIP-relative addressing with labels about xbyak

[herumi]

Thank you for your code. I'll check it.

Thank you for your excellent code.
I merged and modifed your code a little.

You can write as the following code.
Is this your desired specification?

Label label1, label2;
jmp("@f");
L(label1);
  db(a0, 4);
  db(a1, 4);
L("@@");
  mov(eax, ptr [rip + label1]);       // a0
  add(eax, ptr [rip + label1+4]);     // a1
  add(eax, ptr [rip + label2-8+2+6]); // b0
  add(eax, ptr [rip + 16+label2-12]); // b1
  ret();
L(label2);
  db(b0, 4);
  db(b1, 4);

Thank you very much for merging and improving my changes, this is indeed the specification I was hoping for.

Testing it on my project, I found a bug with the modified changes, though:

The following code:
pshufb (xmm2, ptr[rip+myLabel]);
Generates the following instruction:
pshufb xmm0,
(The bug is that xmm2 became xmm0)

This happens because the new code always outputs 0x05 for rip-relative addresses with a label, even if updateRegField was called on the address.

I'm sorry. I fixed it. c81d6d8
Could you try it again?

Thanks, herumi!
I've tested the updated branch and it works great with my project.
