--- Comment #4 from Matthias Kretz (Vir) <mkretz at gcc dot gnu.org> --- So I did a bit of digging. r13-2694-g3e8c4b925a9825 removed the following comment: "The round insn does not trap on denormals.", which matches both the roundps and roundss documentation. So either ceil/floor can be implemented with roundss *and* roundps or neither of them, no?
