I feel we need something like this to avoid the failure of compiling when build with ARM64_ILP32(which will select COMPAT) and ARMV8_DEPRECATED (which depends on the opcodes.o).From f8b8ffdb449491ecf8ba465238bbdb4625a74ac0 Mon Sep 17 00:00:00 2001 From: Bamvor Jian Zhang <bamvor.zhangj...@linaro.org> Date: Mon, 28 Dec 2015 12:57:46 +0800 Subject: [PATCH] arm64: compat: fix wrong dependency of ARMV8_DEPRECATED When compile with ARM64_ILP32, ARMV8_DEPRECATED will be selected due to the dependency of COMPAT.
