Unison is a simple, flexible, and potentially optimal software tool that performs register allocation and instruction scheduling in integration using combinatorial optimization.
Unison has the following dependencies: Haskell platform, Qt (version 4.x), Graphviz library, and Gecode (version 6.0.0). To get the first three dependencies in Debian-based distributions, just run:
apt-get install haskell-platform libqt4-dev libgraphviz-dev
The source of Gecode can be fetched with:
wget https://github.com/Gecode/gecode/archive/release-6.0.0.tar.gz
Just go to the src directory and run:
make build
Unison contains a test suite with a few functions where different targets and optimization goals are exercised. To execute the tests just run:
make test
The building process generates three binaries. The installation process consists
in copying the binaries into the appropriate system directory. To install the
binaries under the default directory usr/local just run:
make install
The installation directory is specified by the Makefile variable PREFIX. To
install the binaries under an alternative directory $DIR just run:
make install PREFIX=$DIR
Unison can be run as a standalone tool but is only really useful as a complement
to a full-fledged compiler such as LLVM. Our LLVM
fork includes a Unison driver built on top
of LLVM's llc code generator. To try it out, just clone the LLVM fork and
follow the instructions in the README.md file from any of the branches with a
-unison suffix.
