From c5cfb62f2bdf51c71ab4b8b33271beab34096c71 Mon Sep 17 00:00:00 2001 From: Marc Zyngier Date: Fri, 28 Dec 2018 00:31:21 -0800 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.
