The latest updates to the CoreGen IR Spec and the StoneCutter Language spec have been released. The latest update permits users to define registers in the CoreGen IR that are designated as program counters (PC). The StoneCutter language also allows users to add this “PC” attribute to registers. The downstream affect of these changes permits the code generation mechanisms to accurately generate signals to automatically update the appropriate signals.
You can find the latest updates to the specs on the respective release pages.
