NAME

rz-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

=

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

BASIC OPERATIONS EXAMPLES (x86)

jmp eax -> eax,eip,=
