[Emerson-general] Rough Instruction Set List

[Alexander F. <af...@en...>]

Here's a rough list of potential opcodes for the Emerson virtual machine. What
are your thoughts?

Arithmetic:

add
subtract
multiply
divide
remainder
negate
shift
AND
OR
XOR
increment
decrement
compare

Classes, Arrays:
new class
new instance of class
new array
get object reference from array of objects
store object reference in array of objects
get value from array
store value in array
get array length
what about type conversions? float-to-integer, etc?

Execution:
goto
throw expection
set breakpoint
jump if equal
jump if not equal
jump if greater than
jump if less than
jump if greater than or equal to
jump if less than or equal to
jump if null (how are we defining "null" within the namespace, by the way? is it
just zero, or some magical voidness?)
temporarily lock object (let's say you're sorting an array; you don't want
another thread to access it)
unlock object
call static method
call instance method
branch to address?

Stack manipulation:
Push value onto stack
Pop value off stack
Swap top two values on the stack

There's a whole crapload I'm probably forgetting or neglecting.
Change whatever you like and add whatever you like!

Regards.
