--- Comment #14 from Kewen Lin <linkw at gcc dot gnu.org> --- > I think that DSE doesn't handle the store IFNs yet - maybe adding handling > to initialize_ao_ref_for_dse would be enough - but I think it cannot yet > handle a "conservative" start (for .MASK_STORES), but .LEN_STORE should > be possible to describe exact by giving an exact trimmed size to ao_ref > (the alias disambiguation changes could be also made more precise there). > Got it, thanks! > Can you open a separate bugreport for the DSE issue? Sure, PR106378 filed.
