Since the release 2.48.5 we get a lowering error in arm.rb regarding the addq instruction. As a workaround we added a case for addq into arm.rb. Here is the compilation error on arm-v7a: cd /data/bsp/platform-board1/build-target/wpewebkit-2.48.5-build/JavaScriptCore/DerivedSources && /data/bsp/platform-board1/sysroot-host/usr/bin/cmake -E env
