From mboxrd@z Thu Jan 1 00:00:00 1970 From: samitolvanen@google.com (Sami Tolvanen) Date: Fri, 3 Nov 2017 10:11:51 -0700 Subject: [PATCH 06/15] efi/libstub: disable LTO In-Reply-To: <20171103171203.107569-1-samitolvanen@google.com> References: <20171103171203.107569-1-samitolvanen@google.com> Message-ID: <20171103171203.107569-8-samitolvanen@google.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org With CONFIG_CLANG_LTO, we produce LLVM IR instead of object files. Since LTO is not really needed here and the Makefile assumes we produce an object file, disable LTO for libstub.
