--- Comment #19 from Andrew Pinski <pinskia at gcc dot gnu.org> --- (In reply to Jakub Jelinek from comment #10) > __builtin_memcpy (&D.35539.D.25336._M_local_buf, "abc", 3); > MEM[(char_type &)&D.35539 + 11] = 0; > change to > __builtin_memcpy (&D.35539.D.25336._M_local_buf, "abc", 4); > seems like something that the strlen pass could do. Actually it is closely related to what simplify_builtin_memcpy_memset (r0-103686-gf46842422035db) does. Maybe I will look into next month.
