It is list as one of the project in project idea document as well. I have a related question. How do we test the different architecture handling without actually run sparse on different platform?

Another way to fix the test suite for now would be let testsuite specify using cgcc instead of sparse directly, for the test source that needs it. That will buy us some time. Fixing sparse properly in the long term obvious would be better.
