Thanks @UkeraGan for your interest at Blacksmith.

Indeed, Blacksmith is not compatible to ARM. For the ARM results we report in the paper, we only exported the Blacksmith patterns as row indices and another code (non-published as dependent on the platform from our collaborator from Qualcomm) used these indices to hammer the patterns.

However, feel free to port Blacksmith to ARM and send a pull request. We would be happy to integrate it properly into the codebase.
