--- Comment #11 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Or is it because of the new pseudo that is created for the temporary? Seems when the combiner is splitting the insns itself using find_split_point, it tries to reuse i2dest if possible for the middle temporary, but I guess the splitters in the md files can't do that, they don't have that information.
