External Open Source Projects Using LLVM 3.3
============================================
An exciting aspect of LLVM is that it is used as an enabling technology for
a lot of other language and tools projects. This section lists some of the
projects that have already been updated to work with LLVM 3.3.
Portable Computing Language (pocl)
----------------------------------
In addition to producing an easily portable open source OpenCL
implementation, another major goal of `pocl <http://pocl.sourceforge.net/>`_
is improving performance portability of OpenCL programs with
compiler optimizations, reducing the need for target-dependent manual
optimizations. An important part of pocl is a set of LLVM passes used to
statically parallelize multiple work-items with the kernel compiler, even in
the presence of work-group barriers. This enables static parallelization of
the fine-grained static concurrency in the work groups in multiple ways.
TTA-based Co-design Environment (TCE)
-------------------------------------
`TCE <http://tce.cs.tut.fi/>`_ is a toolset for designing new
processors based on the Transport triggered architecture (TTA).
The toolset provides a complete co-design flow from C/C++
programs down to synthesizable VHDL/Verilog and parallel program binaries.
Processor customization points include the register files, function units,
supported operations, and the interconnection network.
TCE uses Clang and LLVM for C/C++/OpenCL C language support, target independent
optimizations and also for parts of code generation. It generates new
LLVM-based code generators "on the fly" for the designed TTA processors and
loads them in to the compiler backend as runtime libraries to avoid
per-target recompilation of larger parts of the compiler chain.
