Pranav Bhandarkar 399d97fb12 Enable the reuse of values computed in a previous loop iteration.
This patch adds a pass that removes the computation of provably redundant
expressions that have been computed earlier in a previous iteration. It
relies on the use of PHIs to identify loop carried dependences.

This is scalar replacement for vector types.

Low Level Virtual Machine (LLVM)
================================

This directory and its subdirectories contain source code for LLVM,
a toolkit for the construction of highly optimized compilers,
optimizers, and runtime environments.

LLVM is open source software. You may freely distribute it under the terms of
the license agreement found in LICENSE.txt.

Please see the documentation provided in docs/ for further
assistance with LLVM, and in particular docs/GettingStarted.rst for getting
started with LLVM and docs/README.txt for an overview of LLVM's
documentation setup.

If you are writing a package for LLVM, see docs/Packaging.rst for our
suggestions.
