ESIL - Evaluable Strings Intermediate Language

ESIL aims to describe a Forth-like representation for every target CPU opcode semantics. ESIL representations can be evaluated (interpreted) in order to emulate individual instructions.

Each command of an ESIL expression is separated by a comma

<source0>,<source1>,<operation>
<source>,<destination>,<operation>
<source_destination>,<operation>

These operations should be enough to emulate most instructions of any architecture

=
Set the value of the destination to the value of the source
+
Add the values of source0 and source1 and push the result on the esil stack
-
Subtract the value of source0 from the value of source1 and push the result on the esil stack
*
Multiply the values of source0 and source1 and push the result on the esil stack
/
Divide the value of source1 by the value of source0
