Subject: [PATCH v2 5/7] arm64: fix -m for GNU gold
Date: Thu, 30 Nov 2017 15:39:03 -0800 [thread overview]
Message-ID: <20171130233905.130602-6-samitolvanen@google.com> (raw)
In-Reply-To: <20171130233905.130602-1-samitolvanen@google.com>
GNU gold supports different emulations than bfd. Use aarch64_elf64_*_vec
instead of aarch64linux.
