--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> --- throughputs put aside - how's port allocation and latency figures? That said, GCC usually sides on the smaller insn encoding variant when latency isn't different - we're usually not looking at throughput since throughput figures are quite useless if you look at single insns (and our decision is per individual instruction). Somehow modeling alternatives during scheduling might make more sense but that's not implemented.
