NAME

ESIL − Evaluable Strings Intermediate Language

DESCRIPTION

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.

SYNTAX

Each command of an ESIL expression is separated by a comma
<source0>,<source1>,<operation>
<source>,<destination>,<operation>
<source_destination>,<operation>

BASIC OPERATIONS

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

	=		sets the value of the destination to the value of the source
	+		adds the values of source0 and source1 and pushes the result on the esil stack
	-		subtracts the value of source0 from the value of source1 and pushes the result on the esil stack
	*		multiplies the values of source0 and source1 and pushes the result on the esil stack
	/		divides the value of source1 by the value of source0
