Alive: Automatic LLVM's Instcombine Verifier

============================================

Alive is a tool that can prove the correctness of InstCombine optimizations

specified in a high-level language.

NOTE: Alive is in maintenance mode; no new features are planned. Please try

[Alive2](https://github.com/AliveToolkit/alive2) instead.

Requirements

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

Alive requires Python 2.7.x and Z3 4.3.2 (or later), which can be obtained

from https://github.com/Z3Prover/z3  (use the unstable branch)

Usage

-----

  ./alive.py file.opt

The 'tests' directory has multiple examples of optimizations.

More Information

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

Please see this paper for more details about Alive:

  http://www.cs.utah.edu/~regehr/papers/pldi15.pdf

Online Version

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

Alive is also available online at: http://rise4fun.com/Alive

Generating Benchmarks

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

Alive will automatically generate benchmarks in SMT-LIB 2 format when the

'bench' directory exists and when python is run in non-optimized mode (the

default).

These benchmarks are over the bit-vector theory and may or may not have

quantifiers.
