From: Josh Poimboeuf Date: Thu, 27 Jul 2017 20:56:56 +0000 (-0500) Subject: objtool: Disable GCC '-Wpacked' warnings X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=21ec3bf6aeb4033210747837421e63286ba32646;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git objtool: Disable GCC '-Wpacked' warnings Objtool is failing to build with GCC 4.4.7 due to the following warnings: cc1: warnings being treated as errors In file included from orc.h:21, from orc_gen.c:21: orc_types.h:86: error: packed attribute is unnecessary for ‘sp_offset’ orc_types.h:87: error: packed attribute is unnecessary for ‘bp_offset’ orc_types.h:88: error: packed attribute is unnecessary for ‘sp_reg’ I suspect those warnings are a GCC bug. But -Wpacked isn't very useful anyway, so just disable it.
