Subject: [dpdk-dev] [PATCH 15/15] eal: allow empty set of compile time cpuflags
Date: Mon, 8 Dec 2014 16:59:38 +0800 [thread overview]
Message-ID: <1418029178-25162-16-git-send-email-zlu@ezchip.com> (raw)
In-Reply-To: <1418029178-25162-1-git-send-email-zlu@ezchip.com>
On architectures that do not rely on RTE_COMPILE_TIME_CPUFLAGS, the
compile_time_flags[] array can end up being zero sized. This results in a
compiler complaint in the subsequent loop. Pulling out the array size
computation silences this complaint.
