Subject: [PATCH v2 2/4] RISC-V: Select GENERIC_UCMPDI2 on RV32I
Date: Mon, 25 Jun 2018 16:49:38 +0800 [thread overview]
Message-ID: <e83cbb33e4b72fdef56bfe396131474040a194b7.1529915117.git.zong@andestech.com> (raw)
In-Reply-To: <cover.1529915117.git.zong@andestech.com>
On 32-bit, it need to use __ucmpdi2, otherwise, it can't find the __ucmpdi2
symbol.
