Subject: [Buildroot] [PATCH 3/5] aarch64: ilp32: add ilp32 compiler and linker flags
Date: Mon, 16 Mar 2015 18:00:11 +0800	[thread overview]
Message-ID: <1426500013-1276-4-git-send-email-bamvor.zhangjian@huawei.com> (raw)
In-Reply-To: <1426500013-1276-1-git-send-email-bamvor.zhangjian@huawei.com>

In aarch64, lp64 is the default ABI. Need pass the special flags if
the user want to compile and link ilp32 application.
