i386 decoder shows operands of BT instruction in wrong order
|Assignee:||J. Templ||% Done:|
For the undocumented system-level function SYSTEM.BIT, where offset is not a constant, the decoder shows the operands in the wrong order.
In addition, the bit offset should be treated as an unsigned number when specified as an immediate operand.
