OpenBench (C) 200x - 2018 Rene Rebe, ExactCODE
License: GPL

This is a set of scripts and descriptions in order to create a _open_
SPEC equivalent.

This is in the current state a proof of concept implementation for a
Linux Magazine articles I write, and by no means complete.

But I plan to keep on working on this even after plushing the results
in the article - third parties are invited to comment and contribute.

Ah - and please excuse the sub-optimal download / extracting procedure!
E.g. in the T2 SDE (http://www.t2-project.org) we have far more suprerior
technology - but I needed to rush this together. Complete refactoring
of this is on the TODO.

The scripts and such groupped in this OpenBench are released under the
terms of the GPL v2. - The downloaded source code might have other
licenses.

How-to bench:

If you want to build multiple GCC, automatically:
 - ./download.sh
 - ./build-gccs.sh

Prepare for benchmarking:
 - cd tests

To run all benchmarks for all built compiliers:
 - ./multi-bench.sh -cflags "-Ox -march=whatever" -suffix "Ox" $b $c

To run a set of variants for all built compilers and tests:
 - ./run.sh

To generate pretty plots of the resulting data-points with ploticu:
 - ./stat2.sh
