Parameter map
So this is a debated idea. Would love comments...
Basically, have a parameter map that defines the parameters on the stack and ends with a known signature. Possibly "AWOS" in ASCII or something. Just any signature that denotes the map is ending and the actual parameters are coming. My thoughts on this are --
Pros:
- Makes the parameters known instead of guessed by the function's signature.
- Enables optional parameters and varargs (something FreeBSD doesn't even have).
Cons:
- Would cost A LOT OF TIME
- Would put a lot of pressure/stress on the user-mode side
- Would be VERY SLOW
- Wouldn't be fast
