* The manual lists immediate far destinations as Ap (technically an implicit

|
||||||
|

|

|
*
|
||||||
|
* For memory-only operands, if the emitter functions wants to rely on
|
||||||
|
* generic load and writeback, the decoder needs to know the type of the
|
||||||
|
* operand. Therefore, M is often replaced by the more specific EM and WM
|
||||||
|
* (respectively selecting an ALU operand, like the operand type E, or a
|
||||||
|
* vector operand like the operand type W).
|
||||||
|
*
|
||||||
|
* Immediates are almost always signed or masked away in helpers. Two
|
||||||
|
* common exceptions are IN/OUT and absolute jumps. For these, there is
|
||||||
|
* an additional custom operand type "I_unsigned". Alternatively, the
|
||||||
|
* mask could be applied (and the original sign-extended value would be
|
||||||
|
* optimized away by TCG) in the emitter function.
