From: Iago Toral Quiroga Date: Fri, 20 May 2016 07:38:20 +0000 (+0200) Subject: nir: handle double-precision in fsign, fsat, fnot and frcp X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=38b719d6244e831effe93a5d10e932aad2100984;p=mesa.git nir: handle double-precision in fsign, fsat, fnot and frcp I think these are not strictly necessary since the floats in them should be automatically promoted to doubles when operated with double sources, but it makes things more explicit at least.
