Jonathan Wakely <redi at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Target Milestone|12.5 |14.3 Status|ASSIGNED |RESOLVED Resolution|--- |FIXED --- Comment #17 from Jonathan Wakely <redi at gcc dot gnu.org> --- This can cause problems for code which isn't ready for C++20, as described at https://gcc.gnu.org/gcc-15/porting_to.html#cxx20-iterators As a result, I don't think it should be backported any further, so the performance regression won't be fixed for GCC 12 and 13.
