--- Comment #4 from Aldy Hernandez <aldyh at gcc dot gnu.org> --- BTW, another reason I had to drop the prange work was because IPA was doing their own thing with ranges outside of the irange API, so it was harder to separate things out. So really, all this stuff was related to legacy, which is mostly gone, and my upcoming work on IPA later this cycle should clean up the rest of IPA.
