Subject: [Qemu-devel] [PULL 10/22] fpu/softfloat: move the extract functions to the top of the file
Date: Wed, 21 Feb 2018 11:05:10 +0000	[thread overview]
Message-ID: <20180221110523.859-11-alex.bennee@linaro.org> (raw)
In-Reply-To: <20180221110523.859-1-alex.bennee@linaro.org>

This is pure code-motion during re-factoring as the helpers will be
needed earlier.
