Add
if (i.operands != 3)
abort ();
+ for (x = 0; x < 2; x++)
+ {
^^^ Remove it.
+ if (register_number (i.op[x].regs) != x)
Use
goto bad_register_operand;

+ as_bad (_("can't use register '%s%s' as operand %d in '%s'."),
+ register_prefix, i.op[x].regs->reg_name, x + 1,
+ i.tm.name);
+ }
+ }
+
+ /* Check for third operand for mwaitx/monitorx insn*/
+ if ( register_number (i.op[2].regs) != 2 +
(i.tm.extension_opcode == 0xfb))
^ Remove extra space.
This line is too lone. Please break it into 2 lines:
if (register_number (i.op[x].regs)
!= x + (i.tm.extension_opcode == 0xfb))
+ {
Add a label here
bad_register_operand:
+ as_bad (_("can't use register '%s%s' as operand %d in '%s'."),
+ register_prefix, i.op[x].regs->reg_name, 3,
^^^ Change it to x + 1.
+ i.tm.name);
+ }
+
+ i.operands = 0;
+ }
