BAP ASLi Lifter Plugin

This project contains the ASLi lifter plugin. The file with most of the heavy lifting is a64_lifter.ml. The lifter is able to generate semantics for the armv8 instruction set, using the ASL-interpreter to automatically generate an OCaml representation of the semantics, which are then translated into BIR through this program. In the lifter, if you need to implement a new operation, this page is useful for finding what you have available to you through BAP.

Installation

To build and run this plugin, you'll need:

BAP, likely a version greater than 2.5.0

             --asli-specs=$ASLI_PATH/tests/override.asl

Various scripts are provided in scripts to pass the appropriate options to bap given the ASLI_PATH environment variable is set.
