I suppose all (too lazy to check ALL instructions) floating point instructi= ons are supported in 64-bit code. GNAT's RTL do all necessary software prep= rocessing to obtain good precision. OS do all necessary context store/resto= re operations on task/process switching. You need just to instantiate Ada.N= umerics.Generic_Elementary_Functions and use it. ;)
