no aliasing is possible. In case the user knows no aliasing can happen in the
code the <b>-polly-ignore-aliasing</b> can be used to disable the check for
possible aliasing.
<h3>Importing and exporting JScop files</h3>
The flags <b>-polly-run-import-jscop</b> and <b>-polly-run-export-jscop</b>
allow the export and reimport of the polyhedral representation that Polly
generates for the Scops.
