Subject: [Qemu-devel] [PATCH for-2.11 17/23] tcg/arm: Code rearrangement
Date: Thu, 3 Aug 2017 22:44:20 -0700 [thread overview]
Message-ID: <20170804054426.10590-18-rth@twiddle.net> (raw)
In-Reply-To: <20170804054426.10590-1-rth@twiddle.net>
Move constants before all of the functions.
Move tcg_out_<format> functions before all
of the others. No functional change.
