             A Formal and Executable Model of the x86 ISA
          and the associated x86 Machine-Code Analysis Framework

         Shilpi Goel, Warren A. Hunt, Jr., and Matt Kaufmann

----------------------------------------------------------------------

These files contain a specification of the x86 instruction set
architecture (ISA); we characterize x86 machine instructions and model
the instruction fetch, decode, and execute process using the ACL2
theorem-proving system.  They also contain proofs of correctness of
some x86 machine-code programs.

Up-to-date documentation is available at:
