From: Marc Zyngier <marc.zyngier@xxxxxxx> Subject: scripts/decodecode: set ARCH when running natively on arm/arm64 When running decodecode natively on arm64, ARCH is likely not to be set, and we end-up with .4byte instead of .inst when generating the disassembly. Similar effects would occur if running natively on a 32bit ARM platform, although that's even less popular. A simple workaround is to populate ARCH when it is not set and that we're running on an arm/arm64 system.
