%description
LVM is a robust system, particularly well suited for developing new mid-level
language-independent analyses and optimizations of all sorts, including those
that require  extensive interprocedural analysis. LLVM is also a great target
for front-end development for conventional or research programming languages,
including those which require compile-time, link-time, or run-time optimization
for effective implementation, proper tail calls or garbage collection.

%package polly
Summary:	Polyhedral optimizations for LLVM
License:	MIT
Group:		Development/Other

%description polly
Polly is a polyhedral optimizer for LLVM.

Using an abstract mathematical representation it analyzes and optimizes
the memory access pattern of a program. This includes data-locality
optimizations for cache locality as well as automatic parallelization
for thread-level and SIMD parallelism.

Our overall goal is an integrated optimizer for data-locality and
parallelism that takes advantage of multi-cores, cache hierarchies,
short vector instructions as well as dedicated accelerators.

%description -n clang
clang: noun
    1. A loud, resonant, metallic sound.
    2. The strident call of a crane or goose.
    3. C-language family front-end toolkit.

The goal of the Clang project is to create a new C, C++, Objective C
and Objective C++ front-end for the LLVM compiler. Its tools are built
as libraries and designed to be loosely-coupled and extensible.

%description -n clang-analyzer
The Clang Static Analyzer consists of both a source code analysis
framework and a standalone tool that finds bugs in C and Objective-C
programs. The standalone tool is invoked from the command-line, and is
intended to run in tandem with a build of a project or code base.
