Subject: [PATCH 3/7] alpha: Modernize lib/mpi/longlong.h
Date: Tue, 16 Jul 2013 10:04:36 -0700 [thread overview]
Message-ID: <1373994280-12047-4-git-send-email-rth@twiddle.net> (raw)
In-Reply-To: <1373994280-12047-1-git-send-email-rth@twiddle.net>
Remove the compile warning for __udiv_qrnnd not having a prototype.
Use the __builtin_alpha_umulh introduced in gcc 4.0.
