From 247d1f2190c5530fd18fe92a145d0a1985fca4e4 Mon Sep 17 00:00:00 2001 From: Richard Henderson Date: Fri, 11 May 2018 10:36:25 -0700 Subject: [PATCH] fpu/softfloat: Make is_nan et al available to softfloat-specialize.h MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit 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.
