resources: Fixed incorrect "make clean" command instruction.

This instruction was removing the "dist" directory, which has been
replaced with $(output). This has been fixed.

gem5 Resources

This repository contains the sources needed to compile the gem5 resources. The compiled resources are found in the gem5 resources bucket, http://dist.gem5.org/dist. Though these resources are not needed to compile or run gem5, they may be required to execute some gem5 tests or may be useful when carrying out specific simulations.

The structure of this repository is as follows:

The following sections outline our versioning policy, how to make changes to this repository, and describe each resource and how they may be built.

Versioning

We ensure that for each version of the gem5 source there is a corresponding version of the gem5-resources, with the assumption that version X of the gem5 source will be used with version X of the gem5-resources. The gem5-resources repository contains two branches, develop and master. The master branch's HEAD points towards the latest gem5 resources release, which will be the same version id as the that of the latest gem5 source. E.g., if the latest release of gem5 is v20.2.0.0, then the latest release of gem5-resources will be v20.2.0.0, with the HEAD of its master branch tagged as v20.2.0.0. Previous versions will be tagged within the master branch. Past versions gem5-resources can thereby be checked out with git checkout <VERSION>. A complete list of versions can be found with git tag. The develop branch contains code under development and will be merged into the master branch, then tagged, as part of the next release of gem5. More information on gem5 release procedures can be found here. Any release procedures related to the gem5 source can be assumed to be applicable to gem5-resources.

The compiled resources for gem5 can be found under http://dist.gem5.org/dist/{VERSION}. E.g. compiled resources for gem5 v20.2.0.0 are under http://dist.gem5.org/dist/v20-2-0-2 and are compiled from gem5-resources v20.2.0.0. http://dist.gem5.org/dist/develop is kept in sync with the develop branch, and therefore should not be depended upon for stable, regular usage.

Note: Resource files for gem5 v19.0.0.0, our legacy release, can be found under http://dist.gem5.org/dist/current.

Making Changes

Changes to this repository are made to the develop branch via our Gerrit code review system. Therefore, to make changes, first clone the repository checkout the develop branch:

git clone https://gem5.googlesource.com/public/gem5-resources
git checkout --track origin/develop

Then make changes and commit. When ready, push to Gerrit with:

git push origin HEAD:refs/for/develop

The change will then be reviewed via our Gerrit code review system. Once fully accepted and merged into the gem5-resources repository, please contact Bobby R. Bruce mailto:bbruce@ucdavis.edu to have the compiled sources uploaded to the gem5 resources bucket.
