Also, for testing we really want to be able to run both sets of tests in sandbox, so the parser needs to be run-time selectable. Regards, Simon

To be sure, you would like to have a global variable named, for example, parser which value could be: * parser = "old", for old hush parser * parser = "2021", for "new" hush parser Is my understanding correct? > Regards, > Simon

Yes although an int would be better than a string, perhaps controlled by a flag in global_data and a 'cli' subcommand to change the setting. Regards, Simon

If I understand correctly, that would mean to compile both the old and new parser? Hence, I think I will need to rename some functions in the new parser to avoid problems at this level. > Regards, > Simon

This commit modifies the expected result for hush 2021. Indeed, there were bugs in actual U-Boot hush which were fixed in upstream Busybox. As hush 2021 is based on upstream Busybox, these bugs no longer exist.
