Subject: fpu/softfloat: Make is_nan et al available to softfloat-specialize.h
X-Git-Tag: qemu-xen-4.12.0-rc1~226^2~5
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=247d1f2190c5530fd18fe92a145d0a1985fca4e4;p=qemu-xen.git

fpu/softfloat: Make is_nan et al available to softfloat-specialize.h

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.
