Richard Biener <rguenth at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |NEW Last reconfirmed| |2019-06-12 CC| |rguenth at gcc dot gnu.org Ever confirmed|0 |1 --- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> --- popcount detection is done in niter analysis and I'd put this in there, too (number_of_iterations_popcount). It might be possible to generalize the detection routine rather than creating another one or at least factoring out common bits.
