The Ada front end of GCC has been updated to recognize and perform basic legality checks for the new SPARK attribute At. While full expansion and backend support for GNATprove are not yet implemented, this change enables the attribute to be parsed correctly and ensures its basic usage conforms to SPARK rules. This allows for initial integration with SPARK’s formal verification tools.
