--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> --- So we think the splitting is useful because on one path it exposes that under_curve is unchanged which might expose a jump threading opportunity. Not in this case so the possible jump threading opportunity needs to be further verified by some heuristics (a use in a conditional maybe?).
