Axe-lifters

Axe tools to lift code into logic.

The Axe toolkit provides several tools for lifting code into logic. Currently, Axe can lift JVM bytecode, x86 binaries, and rank-1 constraint systems.

For lifting JVM bytecode, four lifters are available. For code that is unrollable, use unroll-java-code (or try the more experimental unroll-java-code2, for compositional lifting). When loops cannot be unrolled and so must be lifted into recursive functions, use lift-java-code (or try the more experimental lift-java-code2, for compositional lifting).

For lifting x86 binaries, two lifters are available. For code that is unrollable, use x::def-unrolled (still experimental). When loops cannot be unrolled and so must be lifted into recursive functions, try x::lift-subroutine (very experimental).

For lifting rank-1 constraint systems, use r1cs::lift-r1cs or one of its variants.
