Hi, The problem appears in revision 200945 in version 4.9. I attached a one-line patch that fixes it. I also reported this problem at http://gcc.gnu.org/bugzilla/show_bug.cgi?id=57805. In method "write_roots()" in gcc/gengtype.c, the loop on line 4682 should break immediately after "skip_p" is set to "1". All the iterations after "skip_p" set to "1" do not perform any useful work, at best they just set "skip_p" again to "1". Suggested patch: Index: gcc/gengtype.c =================================================================== --- gcc/gengtype.c (revision 200945) +++ gcc/gengtype.c (working copy) @@ -4682,7 +4682,10 @@ for (o = v->opt; o; o = o->next) if (strcmp (o->name, "deletable") == 0 || strcmp (o->name, "if_marked") == 0) - skip_p = 1; + { + skip_p = 1; + break; + } if (skip_p) continue; -Chang
