Subject: [Qemu-devel] [PULL 23/28] fpu/softfloat: Make is_nan et al available to softfloat-specialize.h
Date: Wed, 16 May 2018 08:52:38 -0700 [thread overview]
Message-ID: <20180516155243.16937-24-richard.henderson@linaro.org> (raw)
In-Reply-To: <20180516155243.16937-1-richard.henderson@linaro.org>
We will need these helpers within softfloat-specialize.h, so move
the definitions above the include. After specialization, they will
not always be used so mark them to avoid the Werror.
