Subject: [PATCH 4/7] arm64: fix -m for GNU gold
Date: Wed, 29 Nov 2017 15:44:39 -0800	[thread overview]
Message-ID: <20171129234442.655-5-samitolvanen@google.com> (raw)
In-Reply-To: <20171129234442.655-1-samitolvanen@google.com>

GNU gold supports different emulations than bfd. Use aarch64_elf64_*_vec
instead of aarch64linux.
