Richard Biener <rguenth at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|ASSIGNED |RESOLVED Target Milestone|--- |15.0 Resolution|--- |FIXED --- Comment #8 from Richard Biener <rguenth at gcc dot gnu.org> --- The RTL combiner is now topmost spot at -O3 combiner : 5.39 ( 21%) but I consider this bug fixed now. Thus, fixed for GCC 15. I don't think it's worth backporting this for artificial testcases like this.
