Subject: [Qemu-devel] [PATCH v2 25/27] fpu/softfloat: Make is_nan et al available to softfloat-specialize.h
Date: Fri, 11 May 2018 17:43:09 -0700 [thread overview]
Message-ID: <20180512004311.9299-26-richard.henderson@linaro.org> (raw)
In-Reply-To: <20180512004311.9299-1-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.
